Totals presented in this annual report may not add correctly due to rounding of numbers.
 
For the years 2012, 2013 and 2014, approximately 36%, 52%, and 52%, respectively, of our reserves were evaluated by our internal reserve evaluation staff, and the remaining were based upon estimates prepared by independent petroleum engineering consulting companies and reviewed by us. Our reserve data for 2012, 2013 and 2014 were prepared in accordance with the SEC’s final rules on “Modernization of Oil and Gas Reporting”, which became effective for accounting periods ended on or after December 31, 2009. Except as otherwise stated, all amounts of reserve and production in this report include our interests in equity method investees.
 
In calculating barrels-of-oil equivalent amounts, we have assumed that 6,000 cubic feet of natural gas equals one BOE, with the exception of natural gas from South America, Oceania, and Indonesia in Asia and Yacheng 13-1/13-4 gas field in the Western South China Sea, where we have used energy equivalence for such conversion purpose.
 
Glossary of Technical Terms
 
Unless otherwise indicated in the context, references to:
 
 
 
·
“API gravity” means the American Petroleum Institute’s scale for specific gravity for liquid hydrocarbons, measured in degrees.
 
 
 
·
“appraisal well” means an exploratory well drilled after a successful wildcat well to gain more information on a newly discovered oil or gas reserve.
 
 
 
·
“developed oil and gas reserves” are reserves of any category that can be expected to be recovered:
 
(i) through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and
 
(ii) through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving any well.
 
 
 
·
“exploratory well” means a well drilled to find either a new field or a new reservoir in a field previously found to be productive of oil or gas in another reservoir. Generally, an exploratory well is any well that is not a development well, an extension well, a service well, or a stratigraphic test well.
 
 
 
·
“LNG” means liquefied natural gas.
 
 
 
·
“net wells” means a party’s working interests in wells.
 
 
5

 
 
 
 
·
“proved oil and gas reserves” means those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations— prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.
 
(i) The area of the reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geosciences and engineering data.
 
(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geosciences, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.
 
(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geosciences, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.
 
(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.
 
(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.
 
 
 
·
“PSC” means production sharing contract. For more information about PSC, see “Item 4—Information on the Company—Business Overview—Regulatory Framework in the PRC.”
 
 
 
·
“share oil” means the portion of production that must be allocated to the relevant government entity under our PSCs in the PRC.
 
 
 
·
“undeveloped oil and gas reserves” means reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.
 
(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.
 
 
6

 
 
(ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.
 
(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.
 
For further definitions relating to reserves:
 
 
 
·
“reserve replacement ratio” means, for a given year, total additions to proved reserves, which consist of additions from purchases, discoveries and extensions and revisions of prior reserve estimates, divided by production during the year. Reserve additions used in this calculation are proved developed and proved undeveloped reserves; unproved reserve additions are not used. Data used in the calculation of reserve replacement ratio is derived directly from the reserve quantity reconciliation prepared in accordance with U.S. Accounting Standards Codification 932-235-50, which reconciliation is included in “Supplementary Information on Oil and Gas Producing Activities” beginning on page F-79 of this annual report.
 
Our reserve replacement ratio reflects our ability to replace proved reserves. A rate higher than 100% indicates that more reserves were added than produced in the period. However, this measure has limitations, including its predictive and comparative value. Reserve replacement ratio measures past performance only and fluctuates from year to year due to differences in the extent and timing of new discoveries and acquisitions. It is also not an indicator of profitability because it does not reflect the cost or timing of future production of reserve additions. It does not distinguish between reserve additions that are developed and those that will require additional time and funding to develop. As such, reserve replacement ratio is only one of the indices used by our management in formulating its acquisition, exploration and development plans.
 
 
 
·
“reserve life” means the ratio of proved reserves to annual production of crude oil or, with respect to natural gas, to wellhead production excluding flared gas, also known as reserve-to-production ratio.
 
 
 
·
“seismic data” means data recorded in either two-dimensional (2D) or three-dimensional (3D) form from sound wave reflections off of subsurface geology.
 
 
 
·
“success” means a discovery of oil or gas by an exploratory well. Such an exploratory well is a successful well and is also known as a discovery. A successful well is commercial, which means there are enough hydrocarbon deposits discovered for economical recovery.
 
 
 
·
“wildcat well” means an exploratory well drilled on any rock formation for the purpose of searching for petroleum accumulations in an area or rock formation that has no known reserves or previous discoveries.
References to:
 
 
 
·
bbls means barrels, which is equivalent to approximately 0.134 tons of oil (33 degrees API);
 
 
 
·
mmbbls means million barrels;
 
 
 
·
BOE means barrels-of-oil equivalent;
 
 
 
·
mcf means thousand cubic feet;
 
 
 
·
mmcf means million cubic feet;
 
 
7

 
 
 
 
·
bcf means billion cubic feet, which is equivalent to approximately 28.32 million cubic meters; and
 
 
 
·
BTU means British Thermal Unit, a universal measurement of energy.

FORWARD-LOOKING STATEMENTS
 
This annual report includes “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995, including statements regarding expected future events, business prospects or financial results. The words “expect”, “anticipate”, “continue”, “estimate”, “objective”, “ongoing”, “may”, “will”, “project”, “should”, “believe”, “plans”, “intends” and similar expressions are intended to identify such forward-looking statements.
 
These forward-looking statements address, among others, such issues as:
 
 
· 
the amount and nature of future exploration, development and other capital expenditures,
 
 
·  
wells to be drilled or reworked,
 
 
·  
development projects,
 
 
·  
exploration prospects,
 
 
·  
estimates of proved oil and gas reserves,
 
 
·  
development and drilling potential,
 
 
·  
expansion and other development trends of the oil and gas industry,
 
 
·  
business strategy,
 
 
·  
production of oil and gas,
 
 
·  
development of undeveloped reserves,
 
 
·  
expansion and growth of our business and operations,
 
 
·  
oil and gas prices and demand,
 
 
·  
future earnings and cash flow, and
 
 
·  
our estimated financial information.
 
These statements are based on assumptions and analysis made by us in light of our experience and our perception of historical trends, current conditions and expected future developments, as well as other factors we believe are appropriate under the circumstances. However, whether actual results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual results, performance and financial condition to differ materially from our expectations, including but not limited to those associated with fluctuations in crude oil and natural gas prices, our exploration or development activities, our capital expenditure requirements, our business strategy, whether the transactions entered into by us can complete on schedule pursuant to their terms and timetable or at all, the highly competitive nature of the oil and natural gas industry, our foreign operations, environmental liabilities and compliance requirements, and economic and political conditions in the PRC and overseas. For a description of these and other risks and uncertainties, see “Item 3—Key Information—Risk Factors.”
 
Consequently, all of the forward-looking statements made in this annual report are qualified by these cautionary statements. We cannot assure that the results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected effect on us, our business or our operations.

RISK FACTORS
 
We urge you to consider carefully the risks described below. Although we have established the Enterprise Risk Management system to identify, evaluate and manage risks, our business activities are subject to the following risks, each of which could have a material adverse effect on our operations and financial condition.
 
Risks Relating to Our Operations
 
Our business, revenues and profits fluctuate with changes in oil and gas prices
 
Prices for crude oil may fluctuate widely in response to relatively minor changes in the supply and demand for oil, market uncertainty and various other factors that are beyond our control, including, but not limited to overall economic conditions, consumer demand for oil, political developments, world-wide geopolitical events, armed conflict and acts of terrorism, the ability of petroleum producing nations to set and maintain production levels and prices, the price and availability of other energy sources, domestic and foreign government regulations, and weather conditions.
 
In addition, our typical contracts with gas buyers include provisions for periodic resets and adjustment formulas that depend on a basket of crude oil prices and inflation as well as various other factors. These resets and adjustment formulas can result in natural gas price fluctuations.
 
Even relatively modest declines in crude oil and/or natural gas prices may adversely affect our business, revenues and profits. Lower oil and gas prices may result in the write-off of higher cost reserves and other assets and may lower our earnings or cause losses. Lower oil and gas prices may also reduce the amount of oil and natural gas we can produce economically and render existing contracts that we have entered into uneconomical.
 
The oil and gas reserve estimates in this annual report may require substantial revision as a result of future drilling, testing, production and oil and gas price changes
 
The reliability of reserve estimates depends on a number of factors, including the quality and quantity of technical and economic data, the prevailing oil and gas prices for our production, the production performance of reservoirs, extensive engineering judgments, and the fiscal regime in the PRC and overseas countries where we have operations or assets.

Many of the factors, assumptions and variables involved in estimating reserves are beyond our control and may prove to be incorrect over time. In addition, many of the factors involved in estimating reserves over which we do have control, such as the recovery factor estimates and the projected production decline rates, may also prove to be incorrect over time. Consequently, the results of drilling, testing and production and oil and gas price changes may require substantial upward or downward revisions in our initial reserve data.
 
Any failure to replace reserves and develop our proved undeveloped reserves could adversely affect our business and our financial position
 
Exploring for, developing and acquiring reserves is highly risky and capital intensive. Our exploration and development activities involve inherent risks, including the risk that we will not encounter commercially productive oil or gas reservoirs and the wells we drill may not be productive or not sufficiently productive to recover a portion or all of our investment. In addition, approximately 56.6% of our proved reserves were undeveloped as of December 31, 2014. Our future success will depend on our ability to develop these reserves in a timely and cost-effective manner. There are various risks in developing reserves, mainly including construction, operational, geophysical, geological and regulatory risks.
 
Our future prospects largely depend on our capital expenditures, which are subject to various risks
 
Our ability to maintain and increase our revenues, profit and cash flows depends upon continuous capital spending, which is subject to a number of contingencies, some of which are beyond our control. These variables include: cash flows from operations, the availability and terms of external financing, our ability to execute our project plans and commence production on time, weather conditions, the availability of services and facilities, approvals required from the PRC and foreign governments for certain capital expenditures and investments, and economic, political and other conditions in the PRC and overseas where we have operations or assets.
 
Therefore, our actual capital expenditures and investments in the future may differ significantly from our current planned amounts. If we are unable to obtain sufficient funding for our operations or development plans, our business, revenues, profit and cash flows could be adversely affected.
 
Any failure to implement our natural gas business strategy may adversely affect our business and financial position
 
As part of our business strategy and to meet increasing market demand in China, we continue to expand our natural gas business. In addition to the risks that affect our business generally, this strategy involves certain risks and uncertainties, including our limited market share compared to PetroChina Company Limited, or PetroChina, and China Petroleum & Chemical Corporation, or Sinopec, and the underdeveloped natural gas transportation and supply infrastructure and market in China. We expect that the gap between the market demand and supply for natural gas will continue to narrow down in the next few years and the supply may exceed the demand in certain regions, which may cause challenges to our natural gas business. We are evaluating the options to invest in CNOOC’s LNG projects in China. However, we have not decided whether to exercise these options. The options are subject to various conditions including certain governmental approvals, the prospects of such projects and, if applicable, independent shareholders’ approval.
 
Mergers and acquisitions may expose us to additional risks and uncertainties, and we may not be able to realize the anticipated benefits from mergers and acquisitions
 
In the past few years, we expanded our operations into Argentina, the U.S., Canada, Uganda, United Kingdom, Brazil and certain other countries through mergers and acquisitions. For example, we completed our significant acquisition of Nexen Inc. (“Nexen”), a Canada-based energy company previously listed on the TSX and the NYSE, in February 2013. We may continue to pursue opportunities for mergers and acquisitions to expand our business in the future.

In light of political instability, unexpected changes to fiscal regime and various other factors, there may be uncertainties with respect to the operations of those merged and acquired overseas assets. In particular, we may face increasing exploration and environmental risks arising from Nexen’s unconventional resources development, including oil sands and shale gas. The relatively high production cost of Nexen’s oil sands operations may negatively affect our overall profitability. In addition, acquisitions may result in the incurrence and inheritance of debts and other liabilities, assumption of potential legal liabilities in respect of the acquired businesses, and incurrence of impairment charges related to goodwill and other intangible assets, any of which could harm our results of operations and financial condition. In particular, if any of the acquired businesses fails to perform as we expect, we may be required to recognize a significant impairment charge, which may materially and adversely affect our results of operations. Further, we may face other risks and uncertainties as we become subject to additional regulatory requirements as a result of the acquisition of Nexen. Therefore, we may not be able to achieve the anticipated economic return. Also, the increase in the scale of our operations may increase our operational risks.
 
Achieving the advantages of the Nexen acquisition will depend partly on the efficient combination of the activities of the Company and Nexen, two companies that functioned independently and were incorporated in different countries, with geographically dispersed operations and with different business cultures.
 
The integration process involves inherent costs and uncertainties. We expect the acquisition of Nexen will expand our existing business and assets and create sustainable growth opportunities, synergies and other benefits. However, our anticipated benefits may not develop. In addition, implementation of the acquisition and the successful integration of Nexen will also require management time and attention, as well as those employees with the appropriate skill sets for the tasks associated with such integration. The integration process may also adversely affect our profitability because we will incur additional costs, such as depreciation and employee costs, during this process. Any failures, material delays or unexpected costs of the integration process could therefore have a material adverse effect on our business, results of operations and financial condition.
 
CNOOC largely controls us and we regularly enter into related party transactions with CNOOC and its affiliates

CNOOC indirectly owned or controlled 64.44% of our shares as of March 31, 2015. As a result, CNOOC is able to control the composition of the board of directors of our company, or our Board, determine the timing and amount of our dividend payments and otherwise control us. If CNOOC takes actions that favor its interests over ours, our results of operations and financial position may be adversely affected.
 
In addition, we regularly enter into transactions with CNOOC and its affiliates. Some of our transactions with CNOOC and its affiliates constitute connected transactions under The Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited, or the Hong Kong Stock Exchange Listing Rules. Furthermore, these connected transactions are subject to the review by the Hong Kong Stock Exchange and may also be subject to the prior approval of our independent shareholders. For example, we obtained the independent shareholders’ approval in respect of certain continuing connected transactions under a comprehensive framework agreement with CNOOC and its affiliates on November 27, 2013. If we do not obtain these approvals, we will not be allowed to effect these transactions and our business operations and then the financial condition could be adversely affected.
 
Under current PRC law, CNOOC has the exclusive right to enter into PSCs with foreign enterprises for the petroleum resources exploitation in offshore China. Although CNOOC has undertaken to us that it will transfer all of its rights and obligations under any new PSCs to us, except those relating to its administrative functions, the interests of CNOOC in entering into PSCs with foreign enterprises may differ from our interests, especially with respect to the criteria for determining whether, and on what terms, to enter into PSCs. Our future business development may be adversely affected if CNOOC does not enter into new PSCs on terms that are acceptable to us.
 
 
16

 
 
Our business performance relies heavily on our sales to large domestic customers and a substantial drop in such sales could have a material adverse effect on our results of operations
 
We sell a significant proportion of our production to Sinopec, PetroChina and CNOOC-affiliated companies. However, we currently do not have long-term crude oil sales contracts with these customers. Our business, results of operations and financial condition could be adversely affected if any of them significantly reduced their crude oil purchases from us.
 
We may have limited control over our investments in joint ventures and our operations with partners
 
Quite a few of our operations are conducted with partners or in joint ventures in which we may have limited ability to influence or control their operation or future development. Our limited ability to influence or control the operation or future development of such joint ventures could materially and adversely affect the realization of our target returns on capital and lead to unexpected future costs.
 
Blowout or other incidents may result in platform explosions, fire accidents and oil spills
 
Our operations are mainly conducted in challenging or environmentally sensitive locations, in which the consequences of a blowout, spill, explosion, fire or other incidents could be more severe than in other locations. Although we have adopted standard workflow procedures and various measures to control the risks of blowout or other incidents, we cannot ensure that we could avoid the potential losses caused by blowout or other incidents. If one or more blowout or other incidents occur, platform explosions and fire accidents caused by such incidents may result in casualties, property losses and environmental damages, which may have a material adverse effect on our business, financial condition and results of operation.
 
We maintain various insurance policies for our operations against certain types of potential losses. For detailed information on our insurance coverage, see “Item 4—Information on the Company—Business Overview—Operating Hazards and Uninsured Risks.” However, our ability to insure against our risks is limited by the availability of relevant insurance products in the market. In addition, we cannot assure you that our insurance coverage is sufficient to cover any losses that we may incur, or that we will be able to successfully claim our losses under our existing insurance policies timely or at all. If any of our losses is not covered by our insurance policies, or if the insurance compensation is less than our losses or not paid timely, our business, financial condition and results of operations could be materially and adversely affected.
 
We conduct exploration and development in deepwater areas in both offshore China and overseas by cooperating with our partners and by ourselves. Operations in deepwater may require a significant amount of time between the discovery and the initial production, thus increasing the risks involved in these operations. Also, operations in deepwater are more difficult, risky and costly than those in shallower water and are subject to certain risks including well control and other catastrophic events. The consequences of blowouts and other catastrophic events occurring in deepwater operations can be more difficult, uncertain and time-consuming to remedy.
 
Extreme weather conditions may have a material adverse impact on us and could result in losses that are not covered by insurance
 
Our exploration, development and production activities can be adversely affected by extreme weather conditions, which could result in loss of hydrocarbons, environmental pollution, damage to our properties, cessation of activities, delay of project plans, shareholders lawsuits, government penalty, and increases in costs of drilling, completing and operating wells.
 
We maintain insurance coverage against some, but not all, potential losses. We do not maintain business interruption insurance for all of our oil and gas fields. We may suffer material losses resulting from uninsurable or uninsured risks or insufficient insurance coverage.

The current or future activities of our controlling shareholder, CNOOC, or its affiliates in certain countries that are the subject of U.S. sanctions could result in negative media and investor attention to us and possible imposition of sanctions on CNOOC, which could materially and adversely affect our shareholders
 
We cannot predict the interpretation or implementation of government policy at the U.S. federal, state or local levels with respect to any current or future activities by CNOOC or its affiliates in countries or with individuals or entities that are the subject of U.S. sanctions. Similarly, we cannot predict whether U.S. sanctions will be further tightened, or the impact that such actions may have on CNOOC. It is possible that the U.S. could subject CNOOC to sanctions due to these activities. Certain U.S. state and local governments and colleges have restrictions on the investment of public funds or endowment funds, respectively, in companies that are members of corporate groups with activities in certain countries that are the subject of U.S. sanctions, such as Iran and Sudan. It is possible that the activities of CNOOC or its affiliates may affect the investment in our shares by such U.S. state and local governments and colleges.
 
It is possible that, as a result of activities by CNOOC or its affiliates in countries that are the subject of U.S. sanctions, we may be subject to negative media or investor attention, which may distract management, consume internal resources and affect investors’ perception of our company.
 
In recent years, the U.S. Government has implemented a number of sanctions targeting non-U.S. companies that engage in certain Iran-related transactions. A number of U.S. statutes, Executive Orders and regulations authorize the imposition of sanctions on companies that engage in, among other things, certain activities related to Iran’s energy, petrochemical, shipping or shipbuilding sectors, and in certain instances, on their parent companies. It is possible that the U.S. Government could determine that CNOOC or its affiliates engage in activities targeted by U.S. sanctions. If the U.S. President determined that CNOOC or one of its affiliates engaged in targeted activities, CNOOC and/or its affiliate could be subject to U.S. sanctions, which range from restrictions on U.S. exports or bank financing to outright blocking of CNOOC or its affiliate’s property within U.S. jurisdiction. If the most extreme sanction, blocking, were applied to CNOOC’s property, including controlled subsidiaries, we could be prohibited from engaging in business activities in the U.S. or with U.S. individuals or entities, and U.S. transactions in our securities and distributions to U.S. individuals and entities with respect to our securities could also be prohibited.
 
As required by the Iran Threat Reduction and Syria Human Rights Act of 2012, which added a disclosure requirement to the Securities Exchange Act of 1934, we are providing certain information regarding our non-controlled affiliates’ activities. To our knowledge, in 2014, China Oilfield Services Limited (COSL), one of our non-controlled affiliates, continued to provide certain drilling and other related services in Iran in relation to renewed subcontracting agreements entered into in 2009, as it did in 2013. We cannot predict at this time whether U.S. sanctions will be imposed on any of our affiliates.
 
Our business and financial condition may be adversely affected by a severe and prolonged global economic downturn and adverse economic conditions
 
The global economy has recovered moderately from the recession following the 2008 financial market disruptions and the European sovereign debt crisis. However, concerns about the systemic impact of a prolonged recession and adverse economic conditions, energy costs, geopolitical issues and the availability and cost of credit have contributed to increased market volatility and diminished expectations for economic growth around the world. The complex economic outlook has negatively affected business and consumer confidence and contributed to volatility levels. We cannot predict the short- and long-term impacts of these events on our business and financial condition, which could be materially and adversely affected.
 
Our unconventional oil and gas operations carry additional risks and uncertainties
 
Oil sands, shale oil and gas and coalbed methane (“CBM”) are unconventional oil and gas resources produced through the application of relatively new and expensive technologies. As a result, our unconventional oil and gas operations are subject to the challenges of immature technology and also expose us to higher environmental compliance standards and requirements. In the event of any failure to comply with such standards and requirements, such failure may lead to public concerns on our unconventional oil and gas operations, which may also harm our corporate reputation and profitability.
 
 
18

 
 
 
Our projects may not be completed on time or within budget
 
We are involved with a variety of projects at any given time, including exploration and development projects, and the construction and expansion of projects facilities. Project delays may adversely affect expected revenues and cost overruns may adversely affect project economics. Our ability to complete projects on time and within budget depends on many factors beyond our control, including the need for government and regulatory approvals, especially the approvals from environmental agencies, the availability of equipment and personnel, weather, accidents, equipment breakdown, unexpected or uncontrollable increases in the costs of materials or labor and processing capacity.
 
Oil and gas transportation may expose us to the risk of financial loss and damaged reputation
 
Oil and gas transportation involves certain risks, which may expose us to the risk of financial loss and damaged reputation. Our oil and gas transportation involves marine, land and pipeline transportation, which are subject to hazards such as capsizing, collision, acts of piracy and damage or loss from severe weather conditions, explosion, and oil and gas spills and leakages. These hazards could result in serious personal injury or loss of human life, significant damage to property and equipment, environmental pollution, impairment of operations, risk of financial loss and damaged reputation. We may not be insured against all of these risks and uninsured losses and liabilities arising from these hazards could reduce the funds available to us for capital, exploration and investment spending, which could have a material adverse effect on our business, financial condition and results of operations.
 
Pipeline and export infrastructure in North America is limited
 
An increase in the supply of crude oil and natural gas from unconventional sources in North America has reduced commodity prices in North America relative to many other markets. The increased supply in North America is expected to fill existing North American pipeline infrastructure. Without new transportation and export infrastructure, the current transportation network in North America may not be able to accommodate the increased volumes of crude oil and natural gas expected from the development of unconventional oil and gas, including oil and gas produced from our oil sands and shale gas properties in western Canada. This, in turn, could delay the development of our oil and gas reserves in western Canada. In addition, North America has limited export infrastructure and without new export infrastructure, we may be required to sell our production into the North American markets at lower prices than are available in other markets, which could materially and adversely affect our financial performance.
 
Our lands in western Canada could be subject to aboriginal claims
 
Aboriginal peoples in Canada have claimed aboriginal title and rights to a substantial portion of western Canada, including the lands on which our shale gas and oil sands interests, and those of most other oil sands and shale gas operators in Alberta and British Columbia of Canada, are located. As a result, aboriginal consultation on surface activities is required and may result in timing uncertainties or delays of future development activities. Such claims, if successful, could have a significant adverse effect on our oil sands and shale gas developments in Canada.
 
The energy marketing operations of Nexen expose us to the risk of trading losses
 
Nexen has an energy marketing business, which primarily markets Nexen’s proprietary crude oil and natural gas production and also engages in market optimization activities including the purchase and sale of third-party production. The energy marketing operations of Nexen expose us to the risk of financial losses from various sources, which may have a material adverse effect on our financial performance. Nexen’s energy marketing team maintains a portfolio comprised of long and short physical and financial positions, which may be significant in size or number at any time. This portfolio of positions is managed based on a trading thesis for expected future pricing levels and trends in forward or regional markets. Unanticipated volatility in commodity price levels and trends upon which those positions are based may cause a position to decrease in value. The transportation and storage assets and contracts undertaken by Nexen’s energy marketing business may decrease in value due to changes in temporal and regional commodity pricing.

Risks Relating to the Petroleum Industry
 
The oil and natural gas industries are very competitive
 
We compete in the PRC and international markets with national oil companies, major integrated oil and gas companies and various other independent oil and gas companies for oil and gas properties or leases, customers, capital financing and business opportunities, including desirable oil and gas prospects. We also compete for the equipment and personnel required to explore, develop and operate oil and gas properties. Competition may result in shortage of these resources, customers or opportunities, and also an over-supply of oil and gas, which could negatively impact our business, financial condition and results of operations.
 
Political and security risks and changes in laws and regulations could have an adverse effect on our overseas operation
 
We currently have operations and assets in various foreign countries and regions, including Indonesia, Brazil, Iraq, Australia, Nigeria, Uganda, Argentina, the United States, Canada, United Kingdom and certain other countries, and may expand our operations into other countries to further enhance our reserve base and diversify our geographic risk profile.
 
Some of the countries in which we have operations may be considered politically and economically unstable. A portion of our revenue is derived from operations in these countries. As a result, our financial condition and operating results could be significantly affected by risks associated with international activities, including, civil unrest and general strikes, political instability, risk of war and acts of terrorism, changes in governmental policies or social instability or other political, economic or diplomatic developments in or affecting these foreign nations which are not within our control, including, among other things, a change in crude oil or natural gas pricing policy, expropriation, nationalization, renegotiation or nullification of existing concessions and contracts, cost recovery, taxation policies, foreign exchange and repatriation restrictions, changing political conditions and currency controls.
 
In addition, the operations and assets that we currently have or in the future may have in foreign countries and regions may be materially and adversely affected by trade or economic sanctions that may be imposed by other countries due to their deteriorated relations with each other.
 
Tax and fiscal policies change may have an adverse effect on our financial performance
 
Our financial performance is subject to the tax and fiscal regime in host countries in which we operate. Any changes on the tax and fiscal regime in host countries in which we operate may increase our tax burden and have an adverse effect on our financial performance. For example, in September 2014, OECD launched the “Base Erosion and Profit Shifting Project” to enhance multilateral cooperation, pursuant to which countries worldwide will amend their tax laws and tax treaties and strengthen their supervision on the corporate tax planning and transfer pricing activities, which may cause risks to the Company on transfer pricing activities.
 
War and acts of terrorism could materially and adversely affect us
 
We have operations and assets in various countries and regions, including Indonesia, Brazil, Iraq, Australia, Nigeria, Uganda, Argentina, the United States, Canada, United Kingdom and certain other countries, some of which are deemed to be with a high degree of political risk. We face the risks of kidnapping, damage to property and business interruption caused by terrorism activities and strikes. Acts of terrorism and strikes could materially and adversely affect our business, financial condition and results of operations.
 
 
20

 
 
 
We are required to obtain government or other regulatory approvals in order to operate
 
Our oil and gas operations require approvals from domestic or various international, federal, state, provincial, territorial and local governmental authorities in order to meet the requirement of laws and regulations designed to govern the activities of oil and gas in the process through exploration, development and production. These laws and regulations may impose significant liabilities on a failure to comply with their requirements including the possibility of administrative, civil and criminal penalties, cancellation or suspension of permits or authorizations, investigations or other proceedings. If we are unable to obtain any necessary approvals, our business, financial condition, reputation and results of operations could be materially and adversely affected.
 
We may be penalized if we fail to comply with existing or future environmental laws and regulations
 
Our business is subject to environmental protection laws and regulations in the PRC, as well as other jurisdictions where we operate. The environmental laws and regulations to which we are subject may become increasingly strict and have an increasing impact on our operations. Our compliance with such laws or regulations may require us to incur significant capital expenditures or other obligations or liabilities, which could create a substantial financial burden on us. Furthermore, these jurisdictions may impose fees and fines for the discharge of waste substances or serious environmental pollution, and authorize a government, at its discretion, to close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage.
 
We have established an enterprise risk management system to identify, evaluate and manage the risks that we face. In addition, to help address various health, safety, security, environmental and operational risks, we have established a comprehensive management system to improve our employees’ awareness of our health, safety and environmental policies in our business operations and strengthen their skills of risk identification and risk management. We also continuously focus on workplace safety and prevention of oil spills or other adverse environmental events. However, there can be no assurance that our management systems and controls will function as intended at all times. Substantial liabilities and other adverse impacts could result if our management systems and controls cannot adequately identify all process safety, personal safety and environmental risks or provide effective mitigations, or that our operations will not be able to conform with our management systems and controls at all times.
 
Risks Relating to the PRC
 
Changes in PRC laws and regulations could have an adverse effect on our operation
 
We are the largest producer of offshore crude oil and natural gas in the PRC. The PRC government exercises control over the PRC petroleum industry, including licensing, exploring, producing, distributing, pricing, taxing, importing, exporting and allocating of various resources. We have benefited from various favorable PRC government policies, laws and regulations that have been enacted to encourage the development of the offshore petroleum industry. We cannot guarantee that the legal and fiscal regimes affecting our businesses will remain substantially unchanged or that we will continue to benefit from favorable PRC government policies.

In addition, existing PRC regulations require us to obtain various PRC government licenses and other approvals, including in some cases approvals for amendments and extensions of existing licenses and approvals to conduct exploration and development activities off the shores of China. If we are unable to obtain any necessary approvals, our reserves and production would be adversely affected.
 
Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition
 
 
21

 
 
A portion of our Renminbi revenue may need to be converted into other currencies by our wholly owned subsidiary in the PRC, CNOOC China Limited, to meet our substantial requirements for foreign currencies, including: debt service on foreign currency denominated debt, overseas acquisitions of oil and gas properties, purchases of imported equipment, and payment of dividends declared in respect of shares held by international investors.
 
Foreign exchange transactions under the capital account, including principal payments with respect to foreign currency denominated obligations, are subject to the approval requirements of the State Administration for Foreign Exchange.
 
The value of Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions. The depreciation of Renminbi against the U.S. dollar may cause an increase in cost for imported equipment and materials. In addition, the depreciation of Renminbi against the U.S. dollar may cause an increase in our debt repayment burden, since all of our debt is denominated in U.S. dollars.
 
Certain legal restrictions on dividend distribution may have a material adverse effect on our cash flows
 
We are a holding company. Our businesses are owned and conducted through various wholly owned subsidiaries, including CNOOC China Limited, our wholly owned subsidiary in the PRC. Accordingly, our future cash flows will consist principally of dividends and other distributions from our subsidiaries. Our PRC subsidiary’s ability to pay dividends and other distributions to us is subject to PRC laws and regulations. For example, legal restrictions in the PRC permit payment of dividends only out of profits determined in accordance with PRC accounting standards and regulations. Substantially all our dividend payments result from dividends paid to us as a holding company by CNOOC China Limited. CNOOC China Limited must follow the laws and regulations of the PRC and its articles of association in determining its dividends. As a wholly foreign owned enterprise in China, CNOOC China Limited should provide for a reserve fund and staff and workers’ bonus and welfare fund, each of which is appropriated from net profit after taxation but before dividend distributions according to the prevailing accounting rules and regulations in the PRC. Therefore, there is a risk that we may not be able to maintain sufficient cash flows due to these restrictions on dividend distribution.
 
If the settlement recently reached between the SEC and the Big Four PRC-based accounting firms (including the Chinese affiliate of our independent registered public accounting firm), concerning the manner in which the SEC may seek access to audit working papers from audits in China of US-listed companies, is not or cannot be performed in a manner acceptable to authorities in China and the US, we could be unable to timely file future financial statements in compliance with the requirements of the Securities Exchange Act of 1934.
 
Starting in 2011 all Mainland Chinese audit firms practising before the SEC (including the mainland Chinese affiliate of our independent registered public accounting firm and those of the other "Big Four" networks) were affected by a conflict between US and Chinese laws. Specifically, the SEC and the PCAOB sought to obtain from the Chinese accounting firms access to their audit work papers and related documents from audits in mainland China of the operations of certain US-listed companies.  The Chinese accounting firms were, however, advised and directed that under China law they could not respond directly to the US regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channelled through the China Securities Regulatory Commission ("CSRC").
 
In late 2012 this impasse led the SEC to commence administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the mainland Chinese affiliates of the "Big Four" accounting firms (including the mainland Chinese affiliate of our independent registered public accounting firm). On February 6, 2015, before a review by the Commissioner had taken place, the Chinese accounting firms reached a settlement with the SEC whereby the proceedings were stayed. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC.  The Chinese accounting firms will receive requests matching those under Section 106 of the Sarbanes-Oxley Act of 2002., and are required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the Chinese accounting firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or in extreme cases the resumption of the recently-stayed proceeding against all four firms.  The SEC also reserves the right to resume those proceedings in circumstances where, notwithstanding the accounting firms' compliance with the procedures in the settlement agreement, the SEC does not receive a production of documents which it considers satisfactory (for example because of action or inaction by the Chinese authorities).
 
 
 
In the event that the SEC restarts the administrative proceedings, depending upon the final outcome listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC whose work could contribute to SEC filings, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these accounting firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs may be adversely affected.
 
If the Chinese affiliate of our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act of 1934, as amended. Such a determination could ultimately lead to the delisting of our ordinary shares from the NYSE or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.
 
ITEM 4. INFORMATION ON THE COMPANY
 
HISTORY AND DEVELOPMENT
 
We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Companies Ordinance (Chapter 32 of the Laws of Hong Kong, the predecessor to Chapter 622 of the Laws of Hong Kong, or the Hong Kong Companies Ordinance, which came into effect on March 3, 2014). Our company registration number in Hong Kong is 685974. Under the Hong Kong Companies Ordinance, we have the capacity, rights, powers and privileges of a natural person of full age and may do anything which we are permitted or required to do by our articles of association or any enactment or rule of law. Our registered office is located at 65th Floor, Bank of China Tower, One Garden Road, Central, Hong Kong, and our telephone number is 852-2213-2500.
 
The PRC government established CNOOC, our controlling shareholder, as a state-owned offshore petroleum company in 1982 under the Regulation of the PRC on the Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises. CNOOC assumed certain responsibility for the administration and development of PRC offshore petroleum operations with foreign oil and gas companies.
 
Prior to CNOOC’s reorganization in 1999, CNOOC and its various subsidiaries performed both commercial and administrative functions relating to oil and natural gas exploration and development in offshore China.
 
In 1999, CNOOC transferred all of its then current operational and commercial interests in its offshore petroleum business, including the related assets and liabilities, to us. As a result, we and our subsidiaries are the only vehicles through which CNOOC engages in oil and gas exploration, development, production and sales activities both in and outside the PRC.
 
CNOOC retained its commercial interests in operations and projects not related to oil and gas exploration and production, as well as all of the administrative functions it performed prior to the reorganization.
 
CNOOC has undertaken to us that:
 
 
23

 
 
 
·  
we will enjoy the exclusive right to exercise all of CNOOC’s commercial and operational rights under PRC laws and regulations relating to the exploration, development, production and sales of oil and natural gas in offshore China;
 
 
·  
it will transfer to us all of its rights and obligations under any new PSCs and geophysical exploration operations, except those relating to its administrative functions;
 
 
·  
it will not engage or be interested, directly or indirectly, in oil and natural gas exploration, development, production and sales in or outside the PRC;
 
 
·  
we will be able to participate jointly with CNOOC in negotiating new PSCs and to set out our views to CNOOC on the proposed terms of new PSCs;
 
 
·  
we will have unlimited and unrestricted access to all data, records, samples and other original data owned by CNOOC relating to oil and natural gas resources;
 
 
·  
we will have an option to invest in LNG projects in which CNOOC invested or proposed to invest, and CNOOC will at its own expense help us to procure all necessary government approvals needed for our participation in these projects; and
 
 
·  
we will have an option to participate in other businesses related to natural gas in which CNOOC invested or proposed to invest, and CNOOC will procure all necessary government approvals needed for our participation in such business.
 
The undertakings from CNOOC will cease to have any effect:
 
 
·  
if we become a wholly owned subsidiary of CNOOC;
 
 
·  
if our securities cease to be listed on any stock exchange or automated trading system; or
 
 
·  
12 months after CNOOC or any other PRC government-controlled entity ceases to be our controlling shareholder.
 
For information on our capital expenditures, see “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources—Cash Used in Investing Activities.”
 
BUSINESS OVERVIEW
 
Overview
 
We are an upstream company specializing in the exploration, development and production of oil and natural gas. We are the dominant oil and natural gas producer in offshore China and, in terms of reserves and production, we are also one of the largest independent oil and natural gas exploration and production companies in the world. At the end of 2014, we had net proved reserves of approximately 4.48 billion BOE (including approximately 0.29 billion BOE under our equity method investees). In 2014, we had a total net oil and gas production of 1,184,977 BOE per day (including net oil and gas production of approximately 47,640 BOE per day under our equity method investees).
 
Competitive Strengths
 
We believe that our historical success and future prospects are directly related to a combination of our strengths, including the following:
 
 
·  
large and diversified asset base with significant exploitation opportunities;
 
 
·
sizable operating areas in offshore China with demonstrated exploration potential;
 
 
24

 
 
 
·

Large and diversified asset base with significant exploitation opportunities
 
We have a large net proved reserve base spread across offshore China and globally. As of December 31, 2014, we had approximately 4.48 billion BOE of net proved reserves. Our core operating area, offshore China, contributed to approximately 55.6% of our net proved reserves, while overseas contributed to the balance of 44.4%.
 
In addition to offshore China, we have a diversified global portfolio which provides us with further exploration and exploitation potential. We have a strong track record of successfully acquiring and operating many quality overseas upstream assets worldwide. Currently, we have assets in resource rich countries such as Indonesia, Australia, Nigeria, Uganda, the United States, Canada, the United Kingdom and Brazil.
 
As of December 31, 2014, approximately 56.6% of our net proved reserves were classified as net proved undeveloped. Our large proved reserve base gives us the opportunity to achieve substantial production growth.
 
Sizable operating areas in offshore China with demonstrated exploration potential
 
We are the dominant oil and gas producer in offshore China, a region that we believe has substantial exploration upside. As of December 31, 2014, our total major exploration areas acreage in offshore China was approximately 257,292 thousand km2. We believe that offshore China is relatively underexplored, compared to other prolific offshore exploration areas such as the shallow water of the U.S. Gulf of Mexico, providing us with substantial exploration upside.
 
We have maintained an active drilling exploration program, which continues to demonstrate the exploration potential of offshore China. During 2014, we and our foreign partners have together drilled a total of 117 exploratory wells in offshore China, of which 53 were wildcat wells. During the same year, we and our foreign partners made 15 new discoveries in offshore China.
 
Successful independent exploration and development track record
 
We have a strong record of growing our reserves base for oil and natural gas, both independently and with our foreign partners through PSCs. In recent years, we have been adding reserves and production mainly through independent exploration and development. As of the end of 2014, in offshore China, approximately 84% of our net proved reserves were independent and approximately 74% of our production came from independent projects.
 
In 2014, in offshore China, our independent exploration resulted in 15 new discoveries. We also successfully appraised 17 oil and gas structures. On the development front, in 2014, our major new development projects progressed smoothly with over 10 new projects on stream in offshore China.
 
Access to capital and technology and reduced risks through PSCs in offshore China
 
CNOOC holds exclusive right from the PRC government to enter into PSCs with foreign enterprises relating to the petroleum resources exploitation in offshore China. CNOOC assigned us all of its rights and obligations under then-existing PSCs in 1999 and has undertaken to assign to us its future PSCs except for those relating to its administrative functions. PSCs help us minimize our offshore China finding costs, exploration risks and capital requirements because our foreign partners are responsible for all costs associated with exploration under the usual case. Our foreign partners recover their exploration costs only when a commercially viable discovery is made and production begins.

For more information about PSC, see “Item 4—Information on the Company—Business Overview—Regulatory Framework in the PRC.”
 
Experienced management team and a high level of corporate governance standard
 
Our senior management team has extensive experience in the oil and gas industry. Most of our executives have been with CNOOC, our controlling shareholder, since its inception in 1982. Many of our management team and staff members have worked closely with international partners both within and outside China through numerous joint operations.
 
We have a proven track record of complying with a high level of corporate governance standard, which was recognized by the industry. For example, we were awarded the “ICON on Corporate Governance” by Corporate Governance Asia Magazine and the “2014 Excellence in Management and Corporate Governance Awards-Platinum” by The Asset in 2014.
 
Business Strategy
 
We intend to continue expanding our oil and gas exploration and production activities. The principal components of our strategy are as follows:
 
 
·
focus on reserve and production growth;
 
 
·
develop natural gas business; and
 
 
·
maintain prudent financial policy.
 
Focus on reserve and production growth
 
As an upstream company specializing in the exploration, development, production and sales of oil and natural gas, we consider reserve and production growth as top priority. We plan to increase our reserves and production through drill bits and value-driven acquisitions. We will continue to concentrate independent exploration efforts on major operating areas, especially in offshore China. In the meantime, we will continue to enter into PSCs with foreign partners to lower capital requirements and exploration risks. In 2014, we achieved a reserve replacement ratio of 112%.
 
We increase production primarily through the development of proved undeveloped reserves. As of December 31, 2014, approximately 56.6% of our proved reserves were classified as proved undeveloped, which gives us the opportunity to achieve future production growth, as long as these proved undeveloped reserves are developed faster than the depletion rate of our currently producing reserves.
 
Develop natural gas business
 
We plan to capitalize on the growth potential of the PRC natural gas market, and continue to explore and develop natural gas fields. To the extent we invest in businesses and geographic areas where we have limited experience and expertise, we plan to structure our investments as alliances or partnerships with partners possessing the relevant experience and expertise.
 
In 2014, the large-size gas field Liwan 3-1 in deepwater South China Sea commenced production and our natural gas production would continue to increase accordingly. 
 
Maintain prudent financial policy
 
We will continue to maintain our prudent financial policy. As an essential part of our corporate culture, we continue to promote the cost consciousness among both our management team and other employees. Also, in our performance evaluation system, cost control is always one of the most important key performance indicators.
 
 
26

 
 
 
Aiming to control production cost, we plan to actively promote the regional development of oil and gas field groups and to apply up-to-date offshore engineering, drilling and production technologies to our operations.
 
Currently, we have a strong financial profile. We intend to maintain our financial strength by managing key measures such as capital expenditures, cash flows and costs per BOE. We also intend to actively manage our accounts receivable and inventories to enhance liquidity and improve profitability. We will continue to monitor our foreign currency denominated assets and debts and to manage exposure to foreign exchange rate fluctuations.

The Company books proved reserves for which development is scheduled to commence after more than five years only if these proved reserves satisfy the SEC’s standards for attribution of proved status and the Company’s management has reasonable certainty that these proved reserves will be produced.
 
Qualifications of Reserve Technical Oversight Group and Internal Controls over Proved Reserves
 
Reserve data contained in this disclosure is based on the definitions and disclosure guidelines contained in the SEC Title 17: “Code of Federal Regulations–Modernization of Oil and Gas Reporting–Final Rule” in the Federal Register (SEC regulations), released on January 14, 2009 and related accounting standards. Our proved reserves estimates were prepared using standard geological and engineering methods generally accepted by the petroleum industry, and the definitions and standards of reserves required by the SEC. Generally accepted methods for estimating reserves include volumetric calculations, material balance techniques, production decline curves, pressure transient analysis, analogy with similar reservoirs, and reservoir simulation. The method or combination of methods used is based on professional judgment and experience.
 
For 2012, 2013 and 2014, approximately 36%, 52%, and 52%, respectively, of our reserves were evaluated by our internal reserves evaluation staff, and the remaining were based upon estimates prepared by independent petroleum engineering consulting companies and reviewed by us. Except as otherwise stated, all amounts of reserves in this report include our interests in equity method investees.
 
In 2014, we engaged Ryder Scott Company, L.P. and Gaffney, Cline & Associates (Consultants) Pte Ltd. as independent third party consulting firms to perform annual estimates for our net proved oil and gas reserves under our consolidated subsidiaries. For each independent third party consulting firm, a report of third party letter has been prepared which summarizes the work undertaken, the assumptions, data, methods and procedures they used and provides their reserves estimate. These reports have been included as appendices to this document. Of the total net proved oil and gas reserves evaluated by our internal reserve evaluation staff, we engaged independent third party consulting firms Ryder Scott Company, L.P., McDaniel & Associates Consultants Ltd. and DeGolyer and MacNaughton to perform annual audits for over 86% of the internally evaluated reserves to provide validation of our processes and estimates. For each independent third party consulting firm, a report of third party letter has been prepared which summarizes the work undertaken, the assumptions, data, methods and procedures they used and concludes with their opinion concerning the reasonableness of the estimated reserves quantities or reserves processes. These reports have been included as appendices to this document.
 
Based on the extent and expertise of our internal reserves evaluation resources, our staff’s familiarity with our properties and the controls applied to the evaluation process, we believe that the reliability of our internally generated estimates of reserves and future net revenue is not materially less than that of reserves estimates conducted by an independent qualified reserves evaluator.
 
Besides engaging third parties to provide annual estimates and audits of our reserves, we also implement rigorous internal control systems that monitor the entire reserves estimation procedures and certain key metrics in order to ensure that the process and results of reserves estimates fully comply with the relevant SEC rules. As part of our efforts to improve the evaluation and oversight of our reserves, we established the Reserve Management Committee, or RMC, which is led by one of our Executive Vice Presidents and comprises the general managers of the relevant departments.
 
The RMC’s main responsibilities are to:
 
 
·  
review our reserve policies;
 
 
·  
review our proved reserves and other categories of reserves; and
 
 
32

 
 
 
·  
select our reserve estimators and auditors.
 
The RMC follows certain procedures to appoint our internal reserve estimators and reserve auditors, who are required to have undergraduate degrees and at least five years and ten years of experience related to reserves estimation, respectively.
 
The reserves estimators and auditors are required to be members of a professional society such as China Petroleum Society (CPS), and are required to take the professional training and examinations as required by the professional society and us.
 
The RMC delegates its daily operation to our Reserves Office, which is led by our Chief Reserves Supervisor. The Reserves Office is mainly responsible for supervising reserves estimates and auditing. It reports to the RMC periodically and is independent from operating divisions such as the exploration, development and production departments. Our Chief Reserve Supervisor has over 30 years’ experience in the oil and gas industry.

Engineering Construction, Development and Production
 
In 2014, the Company, by carefully allocating its operational resources, made successful progress in engineering construction and achieved impressive results in engineering construction, development and production operations.

In 2014, the Company’s net oil and gas production reached 432.5 million BOE, representing a year-on-year increase of 5.1%, achieving the production target of 422-435 million BOE set at the beginning of the year. Currently, the new projects planned to commence production in 2014, including Kenli 3-2 oilfields, Wenchang 13-6, Panyu 10-2/5/8, Panyu 34-1/35-1/35-2 and Enping 24-2, all came on stream. The Golden Eagle regional development project in the UK North Sea also started production. Most projects came on stream ahead of schedule. In addition, new projects planned in 2015 including Huizhou 25-8/Xijiang 24-3 oilfield Xijiang 24-1 district joint development project, Liuhua 34-2 gas field and K1A oil sands project in Canada came on stream ahead of schedule in 2014.

In 2014, the Company’s development and production operations were subject to various pressures, including restrained production capacity of Eastern South China Sea gas fields due to weak downstream market demand, uncertainty of a few new projects in meeting the production target, typhoons and significant increases in operating costs of mature oilfields. To address these challenges, the Company implemented the following measures and achieved its annual development and production targets:

First, ensuring the integrity of our production facilities and equipment in oil and gas fields and the safe and stable production, which included: strengthening risk identification systems to achieve record-low number of equipment accidents; optimizing maintenance plans to reduce the impacts on production; and standardizing engineering design to solidify the foundation for reliable set up of equipment and facilities at the design and construction stage.

Through our efforts, new oil and gas fields including the Suizhong 36-1 Phase II Adjustment project, Wenchang 8-3 East and Weizhou 6-12 came on stream during the year, contributing to the Company’s production growth. Through scientific planning and proactive promotion, the workload and production volume contribution of oil, gas and water wells achieved our expectation. Through replacing large pumps, acidifying, workovers and a number of other measures, the decline rate was effectively lowered, thereby maintaining the basic production volume.

Third, actively tracking progress to ensure more infill drilling wells were put into production. In 2014, the number of domestic infill drilling wells put into production and their overall initial production volume exceeded expectations.
 
 
35

 
 
Fourth, promoting the integration of exploration and development, as well as speeding up the construction and production of oil and gas fields. Through collaborative efforts, most development projects commenced production one to two months ahead of schedule.

Fifth, refining the study of reservoirs and improving the development of oilfields to promote stable production. The Company strengthened refined studies on geological reservoirs to ensure the production measures were based on the reservoirs. The increase in infill drilling wells in oilfields such as Bozhong 28-2 South and Bozhong 29-4 contributed to the production growth.

Sixth, strengthening the management of specialized cost items and enhancing efficiency to reduce costs from the roots. In accordance with the requirements of “the Year of Quality and Efficiency”, the Company implemented specialized cost control measures targeting the major subjects of development investment and operating costs, which included: ODP design optimization to control cost from the roots; specialized management of the operating costs of oil wells to improve efficiency and control costs; and specialized management on maintenance costs to fully realize cost control potential.

In 2015, the Company will utilize its full capacity in onshore construction and offshore installation. A total of seven new projects are expected to commence production, including Jinzhou 9-3 oilfield comprehensive adjustment, Bozhong 28/34 oilfields comprehensive adjustment and Kenli 10-1 oilfield. Other oil and gas fields are expected to commence production in the coming years and will inject new impetus into the Company’s production growth in the medium-to-long term.

In 2015, the Company’s development and production is expected to face a relatively harsh external environment, including low oil prices and a weak demand in the natural gas market. The Company will implement its various tasks with emphasis on the following areas:

First, the Company will focus on meeting its annual production target. The Company has set its net production target at 475-495 million BOE in 2015. To achieve this target, we will carefully coordinate our resources to facilitate the timely commencement of production of new projects; control production decline rate and maintain baseline production at existing oil and gas fields; develop natural gas downstream market to release production capacity; optimize planned maintenance of projects; enhance the deployment of measures such as infill drilling wells to increase production; improve the effectiveness of standard measures.

Second, the Company will continue to focus on cost control and efficiency. In 2015, the Company will continue to implement various measures for “the Year of Quality and Efficiency”. The focus of our cost-saving measures with respect to development and production will be directed to the following aspects: adjusting the management model according to better governance; tightening the management of operating costs; optimizing production capital expenditure investment; and introducing innovative management mechanisms to control costs effectively.

Third, the Company will plan in advance the realization of production output in 2016 and 2017. We will strengthen the preliminary research on new projects and review of reservoir plans, accelerate the development of China's natural gas market, and promote the construction of new projects in order to fulfill our medium-to-long term production growth target.

With the above initiatives, the Company will strive to achieve its annual production growth target and lay a solid foundation for its long-term sustainable growth.

The U.S.

The Company currently holds 33.3% interest in two shale oil and gas projects in the U.S., namely the Eagle Ford and Niobrara shale oil and gas projects.

In 2014, along with the increasing number of wells drilled in the Eagle Ford project, we gained a clearer understanding of the underground resources. The Company has worked closely with the operator, and divided the Eagle Ford project into primary production area, secondary production area and potential area according to single-well economics and implemented different operating strategies. By accelerating the development of high-quality assets, production has grown for three consecutive years and its net production reached approximately 53,000 BOE/day. At the same time, the identification of the core region of the Powder River Basin for the Niobrara project began to make contribution to the Company.

Development of shale oil and gas resources has become an important area in upstream oil and gas development, and will support the sustainable growth of the Company.

In addition, the Company owns a number of exploration blocks in the U.S. Gulf of Mexico through its wholly-owned subsidiary, Nexen. In 2014, Nexen made the new discovery of Rydberg in the Gulf of Mexico. The Company also owns interests in several exploration blocks offshore Alaska.

Canada

Canada is one of the world’s major regions with rich oil sands resources. As oil sands are one of the new growth areas of oil and gas exploration and development in the future, participation in oil sands development will be favorable to the sustainable growth of the Company.

In 2013, the Company completed the acquisition of the entire interest of Nexen in Canada. The assets of Nexen are mainly distributed in Canada, the UK North Sea, offshore Nigeria and the U.S. Gulf of Mexico. In Canada, the Company owns the entire working interest in the oil sands project located at Long Lake as well as three other oil sands projects in the Athabasca region in northeastern Alberta.

In 2014, the Company continued the development of the Long Lake project and improved its performance. Its net production increased to approximately 31,000 BOE/day. For the oil sands project in Canada, the Company will leverage its overall advantages, improve cost efficiency and control the pace of investment to provide a solid resource safeguard for its long-term development.

In addition, the Company holds 12.39% of the shares of MEG Energy Corporation in Canada, which is listed on the Toronto Stock Exchange. The Company also owns a 60% interest in Northern Cross (Yukon) Limited, which owns oil and gas exploration blocks in the Yukon area in Canada.

Other Regions in North America

The Company owns a 12.5% interest in the 2C block and a 12.75% interest in the 3A block in Trinidad and Tobago, of which the 2C block is in production. In 2014, with the region's crude oil entering the post development stage, the Company reduced accidental shutdowns and increased the production efficiency by optimizing gas injection, facilities and equipment integration management, maintenance and other measures, resulting in production volume that exceeded the Company’s expectation.

South America

In South America, the Company mainly holds a 50% interest in Bridas Corporation (“Bridas”) in Argentina and a 10% interest in the PSC of the Libra oilfield in Brazil, among which, the Company’s 50% interest in Bridas is accounted for by the equity method. At the end of 2014, the Company’s reserves and daily production volume derived from South America reached 293.5 million BOE and 46,963 BOE/day, respectively, representing approximately 6.6% and 4.0%, respectively, of the Company’s total reserves and daily production.

Argentina

The Company and Bridas Energy Holding each hold 50% shareholding interest in Bridas and make joint management decisions. Bridas holds 40% interest in Pan American Energy (“PAE”) in Argentina. Bridas is engaged in oil and gas exploration and production activities in Argentina mainly through its affiliates (including the interest in PAE).

In 2014, the Company strove to maintain normal operations and production in the operating areas, and endeavored to overcome the bottleneck of operational resources, coordinate resources and improve operational efficiency. The production of Bridas increased slightly to approximately 46,000 BOE/day.
 
 
Brazil

The Company holds a 10% interest in the Libra PSC, a deepwater pre-salt project in Brazil. The oilfield is located in the Santos Basin, with a block area of about 1,550 km2 and a water depth of about 2,000 meters.

In 2014, the exploration and appraisal work on the Libra project progressed smoothly. The drilling of the NW1 well further reinforced the confidence for exploration and appraisal in the block.

Brazil is one of the world’s most important deepwater oil and gas development regions. The Company will fully leverage the development opportunities in Libra, Brazil to establish a new production growth point.

Other Regions in South America

In South America, the Company also holds interests in several exploration and production blocks in Colombia.

Europe

The Company holds interests in several oil and gas fields such as Buzzard and Golden Eagle in the UK North Sea. At the end of 2014, the Company’s reserves and daily production volume derived from Europe reached 152.5 million BOE and 96,370 BOE/day, respectively, representing approximately 3.4% and 8.1%, respectively, of the Company’s total reserves and daily production.

United Kingdom

The Company’s asset portfolio in the North Sea consists of projects under production, development and exploration, mainly including: a 43.2% interest in the Buzzard oilfield, one of the largest oilfields in the North Sea, making the Company one of the largest crude oil producers in the North Sea, and a 36.5% interest in the Golden Eagle block which commenced production in 2014.

In 2014, the Company made two new discoveries in the North Sea, namely, Blackjack and Ravel.

The United Kingdom is one of the Company’s key overseas development areas as several key projects such as Buzzard and Golden Eagle contributed considerably to the Company’s production. In 2014, the net production of Buzzard oilfields reached approximately 68,000 barrels per day. In the future, we will continue to intensify our efforts on the oil and gas development in the UK, and actively look for potential exploration and development blocks in order to achieve a stable and sustainable development in the region.

Delivery Commitment
 
We have certain delivery commitments under the take-or-pay contracts for sales of natural gas. In 2014, the annual sales from our largest gas contract contributed to only approximately 0.3% of our total oil and gas sales and the total revenues from gas sales accounted for approximately 6.3% of our total revenues in 2014. Moreover, the total gas quantities that are subject to delivery commitments under existing contracts or agreements are not significant to the Company. Therefore, we believe that we did not have any material delivery commitment as of the end of 2014.
 
Sales and Marketing
 
Sales of Crude Oil
 
The Company sells its crude oil produced offshore China to the PRC market mainly through CNOOC China Limited, its wholly-owned subsidiary. The Company sells its crude oil produced overseas to international and domestic markets mainly through another wholly-owned subsidiary, China Offshore Oil (Singapore) International Pte Ltd. Nexen Energy ULC, a wholly-owned subsidiary of the Company, located in Canada, sells its crude oil and synthetic oil to international markets separately.

The Company’s crude oil sales prices are mainly determined by the prices of international benchmark crude oil of similar quality, with certain premiums or discounts subject to prevailing market conditions. Although the prices are quoted in U.S. dollars, customers in China usually pay Renminbi. The Company currently sells three types of crude oil in China, namely, heavy crude, medium crude and light crude, which are benchmarked by Duri, Daqing, and Tapis, respectively, all of which are the benchmarking crude oil prices in the Far East. The Company’s major customers in China are Sinopec Petrochina and CNOOC. The crude oil produced overseas and sold in the international markets is benchmarked at the Brent and WTI oil prices.

In 2014, the world economy has lost its growth momentum, and global oil supply became relatively sufficient. Affected by the U.S. shale gas production, geopolitical and market factors, the international oil prices began to fall sharply from the second half of the year. The overall fuel oil market in Asia was negatively affected by its weak supply and demand ratio and the movement of international crude oil futures, resulting in a relatively weak growth trend.

Due to the sharp decline in international oil prices as well as the weaker economic fundamentals and demand for oil products in the Asia-Pacific region as compared to the previous year, there was a relatively high pressure on the selling price of the Company’s crude oil. In 2014, the Company’s average realized oil price was US$96.04/barrel, representing a decrease of 8.2% from the previous year.
 
The table below sets forth the sales and marketing volumes in offshore China for each of these types of crude oil for the periods indicated.

Sales of Natural Gas

The Company’s natural gas sales prices are mainly determined by the Company’s negotiations with its customers. The Company’s natural gas sales agreements are generally long-term contracts, which normally provide a periodic price adjustment mechanism. The Company’s natural gas customers are primarily located in the Southeastern coast of China and mainly include Hong Kong Castle Peak Power Company Limited, CNOOC Gas and Power Group, China BlueChemical Ltd, etc.

The LNG sourced by the Company from the North West Shelf LNG Project in Australia and the Tangguh LNG Project in Indonesia is mainly based on long-term supply contracts and is sold to various customers in the Asia-Pacific region, including LNG Terminals in Dapeng, Guangdong and Putian Fujian, China.

In 2014, the natural gas sales of the Company were under pressure due to the weak demand of coastal Southern China. The Company’s average realized natural gas price was US$6.44/mcf, representing a 11.4% increase over the previous year, primarily due to: on the one hand, benefiting from the Chinese government’s gradual onshore natural gas price reform, the Company adjusted its sales price to major natural gas customers through negotiation; on the other hand, the production from new gas fields recorded higher prices; there was also an increase in the sales price of natural gas in certain regions overseas.

To cope with the current shortage of natural gas demand by downstream users, the Company will coordinate related designs, approvals and gas price negotiations with downstream customers, with an aim to promote a stable production of oil and gas fields in production and the development of oil and gas fields under construction.

Apart from the above sales activities, Nexen, a wholly-owned subsidiary of the Company, is engaged in the purchase and sales of oil and gas products from third parties, as well as trading derivatives to mitigate risks arising from oil and gas price fluctuations.
 
The table below sets forth the average realized prices for our crude oil and natural gas for the periods indicated.

Procurement of Services
 
We usually outsource work in connection with the acquisition and processing of seismic data, well drilling, well logging and perforating services and well control and completion service to independent third parties, or CNOOC and its affiliates.
 
Besides building floating production storage and offloading, or FPSO, with our partners, we employ independent third parties or CNOOC and/or its affiliates for FPSO services and other services.
 
We conduct a bidding process to determine who we employ to construct platforms, terminals and pipelines, to drill production wells and to install offshore production facilities. Both independent third parties and CNOOC affiliates participate in the bidding process. We are closely involved in the design and management of services by contractors and exercise extensive control over their performance, including their costs, schedule, quality and health, safety, and environment measures.
 
Research and Development
 
In 2014, the Company continued to implement its “Technology-driven Strategy” through further reform in science and technology systems as well as improving its technological innovation system. The Company set up scientific research platform construction projects, such as the “National Engineering Laboratory Phase I Project for Offshore Oil Exploration”, to improve the capability of its proprietary innovation. The Company increased reserves and production and enhanced cost efficiency through technological innovation, with certain research findings being applied to operations and generating positive results. “The Development and Application of Ultradeepwater Semi-submersible Drilling Platform” and “The Critical Technology and Industrial Application of Offshore Drilling Riserpipe” were honored with the Special National Technological Progress Award of China and Second prize of National Technological Invention Award ,respectively, in 2014.
 
Major Scientific Project Development
 
In 2014, with a view to strengthen key technologies and to provide support for sustainable development, the Company focused on major directions and technologies which included: exploration and development technology for deepwater oil and gas fields, offshore heavy oil fields and fields with low porosity and permeability, production enhancement at producing fields, offshore oil and gas fields regional development and marginal fields development, and development of high-temperature/ ultra-pressure and high-temperature/ low-pressure gas fields in South China Sea.

In addition, the Company undertook a number of national science and technology projects such as “Development of Large-scale Oil and Gas Fields and Coalbed Methane” and obtained various achievements such as geological understanding of and exploration breakthrough in offshore large-scale oil and gas fields, establishing a demonstration base for efficient development technology of offshore heavy oilfields, and completing the development of the Liwan 3-1 deepwater gas field in South China Sea.
 
Innovative Development of Key Technologies
 
In 2014, major technological innovations and developments achieved by the Company included:

First, relying on the national research and internal research, Lingshui 17-2-1 was tested to flow the highest daily rate in the independent gas fields offshore China and the first major natural gas discovery was made in the independent deepwater exploration for the Company.

Second, the efficient development of offshore heavy oilfield achieved remarkable results, representing research, production and service capabilities of full range of sands control and well completion tools, and the representative thermal recovery test sites at Nanbao 35-2 and Luda 27-2 were built.

Third, the Company successfully developed a high-temperature low-free water drilling fluid system and ancillary chemical products, with their successful application at a high temperature of 164℃. The Company also successfully developed China's first submerged umbilical production system. Both of the above developments filled the technology gap in China.

In addition, the Company also made breakthroughs in key technologies including the large-scale long-distance flexible HVDC for offshore oilfields, and completed an integrated intelligent monitoring system along with project demonstration.

 
Health, Safety and Environmental Protection, or HSE
 
As an offshore exploration and production company, we face considerable operational safety and environmental protection risks. Therefore, the Company has been placing a great deal of emphasis on health, safety and environmental protection (HSE) issues. Promoting a philosophy and culture of HSE among its employees, the Company strives to establish a comprehensive management system to improve employees’ awareness of HSE during operations and to strengthen their ability to identify potential risks as well as their risk management skills.

In 2014, along with the rapid growth of the Company’s business, the scope of management in health, safety and environmental protection also expanded accordingly and the Company faced greater challenges. For these reasons, the Company continued to improve its management system, promoted intrinsic safety management and strengthened supervision, inspection and training in these areas. As a result, the Company achieved stable performance in the areas of health, safety and environmental protection and met the respective yearly targets. No oil spill accidents above a small size were recorded throughout the year. In production activities, the operation of the health, safety and environmental protection system was effective.

Offshore China, the Company carried out special inspections of offshore oil and gas projects and implemented measures to prevent potential accidents. Considering the work allocation for the year’s key tasks and the actual operations of the relevant organizations, the Company’s headquarter organized an inspection team, which consisted of relevant experts from various functional departments, their affiliated units and intermediary institutions in charge of safety technologies, to conduct random inspections of four branches according to the inspection list. Based on the issues discovered, we were able to make solid progress in detecting and managing potential risks.

In addition, the Company further strengthened its management of pollutant discharge to promote energy savings and emission reductions.

For overseas projects, in accordance with the characteristics of different countries, regions, cultures, cooperation models, local legal environments as well as project durations and nature of operations, the Company enhanced its study on the countries and regions of operation and conducted dynamic evaluations on potential risks. The Company has been closely tracking and making scientific judgments on the safety situations of such countries and regions, which increased its risk identification ability and facilitated the formulation of targeted HSE management plans for overseas projects. In 2014, the Company completed HSE management plans for three overseas subsidiaries and conducted one senior audit. During the year, the Occupational Safety and Health Administration (“OSHA”) statistics of Nexen reached the best standard on record.

To obtain health, safety and environmental protection information, the Company utilized an environmental management information system to realize immediate pollutants tracking in offshore China, and adopted categorized management on operational risks with the risk identification system.

In 2014, there were no accidents causing critical casualties. The Company’s OSHA statistics were maintained at a good level, and the Company’s performance continued to improve.

Operating Hazards and Uninsured Risks
 
Our operations are subject to hazards and risks inherent in the drilling, production and transportation of crude oil and natural gas, including pipeline ruptures and spills, fires, explosions, encountering formations with abnormal pressures, blowouts, cratering and natural disasters, any of which can result in loss of hydrocarbons, environmental pollution and other damage to our properties and the properties of operators under PSCs. In addition, certain of our crude oil and natural gas operations are located in areas that are subject to tropical weather disturbances such as typhoons, some of which can be severe enough to cause substantial damage to facilities and interrupt production.
 
As part of the protection against operating hazards, we maintain insurance coverage against some, but not all, potential losses, including the loss of wells, blowouts, pipeline leakage or other damage, certain costs of pollution control and physical damages on certain assets. Our insurance coverage includes offshore oil and gas field properties all risks insurance and construction insurance, protection and indemnity insurance, operator extra expenses insurance, marine cargo insurance and third party liabilities and comprehensive general liability insurance. The operators of the projects in which we participate overseas are required by local law to purchase insurance policies customarily taken out by international oil and gas companies.
 
We also carry third-party liability insurance policies to cover (i) claims made against us by or on behalf of individuals who are not our employees in the event of personal injury or death and (ii) legal liabilities for environmental damages resulting from our onshore and offshore activities, including oil spills. In addition, we impose contractual requirements upon our contractors to purchase insurance policies that cover their liabilities for the personal injuries of their own employees. Our contractors are obligated to indemnify us against such claims.
 
As of December 31, 2014, we have purchased a number of insurance policies with varying policy coverage and limits to meet our risk management requirements and cover our potential liabilities arising from accidents at any of our offshore and onshore locations. We maintain insurance for costs relating to property damage to our facilities, control of well including drilling relief wells, removal of wreck, pollution clean-up, liability for bodily injury and property damage to third parties. The policy limits and other terms and conditions of these insurance policies comply with all applicable laws and regulations in the PRC and other relevant jurisdictions. However, we may not have sufficient coverage for some of the risks we face, either because insurance is not available or because of high premium costs. See “Item 3—Key Information—Risk Factors—Risks Relating to Our Operations—Extreme weather conditions may have a material adverse impact on us and could result in losses that are not covered by insurance.”
 
Excluding Nexen’s operation and Nexen’s assets, we have maintained varied insurance policies for our assets and operational insurance policies and construction insurance policies, with different policy limits and deductibles. We also purchase operator’s extra-expense up to US$ 100 million and third-party liabilities insurance up to US$200 million for our working interests. As for deep-water wells, we are insured for our working interest up to US$250 million for costs related to control of the well. The deductible for each insurance policy mainly ranges from US$2 million to US$5 million for different types of insurance policies. For Nexen, we are insured for amounts up to the replacement cost value of our assets for property damage and up to US$425 million for operators extra expense. Additionally, we purchase insurance covering liability for bodily injury and property damage to third parties with limits of up to US$900 million. This cover protects against liability that arises from sudden and accidental pollution or from other causes. For declared deep-water wells, we are insured for our working interest share of up to US$750 million for costs related to control of the well.
 
For all of our offshore operations, we have conducted comprehensive environmental impact evaluations and adopted emergency plans to deal with potential oil spills. Pursuant to the requirements of the PRC government, the evaluations and plans for our offshore operations in the PRC have been reviewed and approved by the industry experts and have been filed with the PRC government. The evaluations and plans for our offshore operations overseas have complied with the legal and regulatory requirements of the relevant local jurisdictions.

In addition, we currently have seven oil spill emergency response bases, to which we have contributed land and funds for construction, separately located in eight cities in the PRC, namely Suizhong, Tanggu, Longkou, Huizhou, Shenzhen, Zhuhai, Weizhou and Gaolan. All the oil spill emergency response bases are close to our workplaces of operations, and in the event of any oil spill, explosion or other similar events, they would react promptly and assist us in coping with such accidents effectively. We have developed and established a “four-in-one” emergency management system to support our worldwide business, which includes a crisis management plan, an emergency commanding system, an emergency information system and an emergency rescue team. Through constant trainings and exercises, we have comprehensively enhanced our ability to defend risks, minimize the impact of emergency events and maintain our sustainable development.
 
Competition
 
Domestic Competition
 
The oil and gas industry is very competitive. We compete in the PRC and in international markets for customers as well as capital to finance our exploration, development and production activities. Our principal competitors in the PRC are PetroChina and Sinopec.
 
We price our crude oil on the basis of comparable crude oil prices in the international market. The majority of our customers for crude oil are refineries affiliated with CNOOC, Sinopec and PetroChina to which we have been selling crude oil, from time to time. Based on our past experiences with these refineries, we believe that we have established stable business relationships with them.
 
We are the dominant player in the oil and gas industry in offshore China and, through CNOOC, are the only company permitted to engage in oil and gas exploration and production in offshore China with foreign parties under PSCs. We may face increasing competition in the future from other oil and gas companies in obtaining new PRC offshore oil and gas properties, or, as a result of changes in current PRC laws or regulations permitting an expansion of existing companies’ activities or new entrants into the industry.
 
As part of our business strategy, we intend to expand our natural gas business to meet rapidly increasing domestic demand. Our principal competitors in the PRC natural gas market are PetroChina and Sinopec.
 
Foreign Competition
 
Imports of crude oil are subject to import licenses, handling fees and other restrictions. The PRC government also restricts the availability of foreign exchange with which the imports must be purchased. The combination of licenses and restrictions on foreign exchange has, to some extent, limited the competition from imported crude oil.
 
As a result of China joining the World Trade Organization as a full member on December 11, 2001, it is required to further reduce its import tariffs and other trade barriers over time, including with respect to certain categories of petroleum and crude oil. At present, CNOOC, Sinopec, PetroChina and several other domestic state-owned enterprises have received permission to import crude oil on their own. Foreign owned or foreign invested entities and other non-state-owned enterprises are subject to certain import quotas.

We are mainly engaged in the exploration, development, production and sales of crude oil and natural gas primarily in offshore China. For the year ended December 31, 2014, approximately 65.1% of our total revenue was sourced in the PRC. Our overseas activities are mainly conducted in Canada, the United States of America, United Kingdom, Nigeria, Argentina, Indonesia, Uganda and Australia, etc.
 
Regulatory Framework in the PRC
 
Government Control
 
All of China’s petroleum resources are owned by the PRC state. The PRC government exercises regulatory control over oil exploration and production activities in China. We are required to obtain various governmental approvals, including those from the Ministry of Land and Resources, the State Oceanic Administration, the National Development and Reform Commission and the State Administration of Work Safety before we are permitted to conduct production activities. Our sales are coordinated by the National Development and Reform Commission. For independent operations and joint exploration and production with foreign enterprises, we are required to obtain various governmental approvals, through CNOOC, including permits for exploration blocks, approval of a reserve report, environmental impact reports submitted through CNOOC, extraction permits and work safety permits. Moreover, for joint exploration and production, we are required, through CNOOC, to obtain approval of overall development plan from the National Development and Reform Commission, and to report the circumstances and situation of the PSCs or other cooperation contracts between CNOOC and the foreign enterprises to the Ministry of Commerce.
 
We explore and develop our offshore China reserves under exploration and production licenses granted by the PRC government. Exploration licenses, which are generally granted for individual blocks, require holders to make an annual minimum exploration investment and pay an annual exploration license fee. The annual minimum investment and license fees are based on the area under license and increase over the life of the exploration license. Production licenses, which are generally granted for individual fields, require holders to pay an annual production right usage fee based on the area under license. All of our proved reserves in offshore China are under production licenses granted by the PRC government.
 
Since the early 1980s, the PRC government has adopted policies and measures to encourage the development of the offshore petroleum industry. These policies and measures, which were applicable to CNOOC’s operations prior to the reorganization, became applicable to our operations in accordance with an undertaking agreement between us and CNOOC. As approved by the PRC government, these policies and measures have provided us with benefits mainly including the exclusive right to explore for, develop and produce petroleum in designated areas in offshore China in cooperation with foreign enterprises and to sell petroleum in China, and the flexibility to set our prices in accordance with international market prices and determine where to sell our crude oil.
 
Although we historically have benefited from the foregoing special policies, we cannot assure that such policies will continue in the future.

Fiscal Regimes for Independent Operations
 
Taxation
 
We are subject to income taxes on an entity basis on income arising in or derived from the tax jurisdictions in which we and each of our subsidiaries are domiciled and operate. Our profits arising in or derived from Hong Kong are subject to tax at a rate of 16.5%.
 
We received a formal approval from the State Administration of Taxation of the PRC on October 19, 2010, confirming that we are regarded as a Chinese Resident Enterprise, or CRE. According to the formal approval, we are subject to the PRC corporate income tax at a rate of 25% starting from January 1, 2008. The corporate income tax we pay in Hong Kong can be credited against our PRC corporate income tax liability.
 
We are required to withhold 10% corporate income tax when we make dividend distributions to our non-Chinese resident enterprise shareholders.
 
Our PRC subsidiary, CNOOC China Limited, as a wholly foreign-owned enterprise, is subject to an enterprise income tax rate of 25% under the prevailing tax rules and regulations.
 
The PRC corporate income tax is levied based on taxable income, including income from both operations and other components of earnings, as determined in accordance with the generally accepted accounting principles in the PRC, or PRC GAAP.
 
Besides income taxes, our PRC subsidiary also pays certain other taxes, including:
 
·  
production taxes at the rate of 5% on independent production and production under PSCs;
 
·  
resource taxes at the rate of 5% (reduced tax rates may apply to specific products and fields) on the oil and gas sales revenue (excluding production taxes) derived from oil and gas fields under production sharing contracts signed after November 1, 2011 and independent offshore oil and gas fields starting from November 1, 2011, which replaced the royalties for oil and gas fields except for those under production sharing contracts signed before November 1, 2011. The resource tax rate has been changed from 5% to 6% since December 1,2014;
 
·  
mineral resource compensation at the temporary rate of 1%  (reduced tax rates may apply) on the oil and gas sales revenue derived by oil and gas fields under production sharing contracts signed after November 1, 2011 starting from November 1, 2011. The rate decreased to zero since December 1, 2014;
 
·  
export tariffs at the rate of 5% on the export value of petroleum oil;
 
·  
business tax at the rates of 3% to 5% or value-added tax at the rate of 6% on other income;
 
·  
city construction tax at the rates of 1% or 7% on the actual paid production taxes, business tax and value-added tax;
 
·  
educational surcharge at the rate of 3% on the actual paid production taxes, business tax and value-added tax; and
 
·  
local educational surcharge at the rate of 2% on the actual paid production taxes, business tax and value-added tax.
 
We calculate our deferred tax to account for the temporary differences between our tax base, which is used for income tax reporting and prepared in accordance with applicable tax guidelines, and our accounting base, which is prepared in accordance with applicable financial reporting requirements. The temporary differences include accelerated amortization allowances for oil and gas properties, which are partially offset by provisions for dismantlement and for impairment of property, plant and equipment and write-off of unsuccessful exploratory drilling. As of December 31, 2012, 2013 and 2014, we had Rmb 3,363 million, Rmb 22,633 million and Rmb 14,312 million (US$ 2,307 million) respectively, in net deferred tax liabilities. See note 12 to our consolidated financial statements included elsewhere in this annual report.
 
 
54

 
 
 
Royalty
 
Royalties paid to the PRC government are based on our gross production from both independent operations and oil and gas fields under PSCs. The amount of the royalties varies up to 12.5% based on the annual production of the relevant property. The PRC government has provided us, among other companies, with a royalty exemption in each field for up to one million tons, or approximately seven million BOE, per year for our crude oil production and for up to 2 billion cubic meters (approximately 70.6 billion cubic feet or 11.8 million BOE) per year for our natural gas production. The limits in these exemptions apply to our total production from both independent properties and properties under PSCs.
 
In 2011, the State Council of the PRC amended the Provisional Regulation of PRC Resource Tax. As a result, since November 1, 2011, the royalties payable to the PRC government have been replaced by resource tax, currently at 6% (5% before December 1, 2014) of the sales revenues from crude oil and natural gas. The PSCs that were signed before November 1, 2011 are not affected by the amendment of the Provisional Regulation of PRC Resource Tax and we continue to pay royalties to the PRC government for these PSCs.
 
Special Oil Gain Levy
 
In March 2006, the PRC government imposed a special oil gain levy at progressive rates from 20% to 40% on any income derived from sales of locally produced crude oil by an oil exploration and production company at a price that exceeds US$40 per barrel. In December 2011, the PRC government increased the threshold of the special oil gain levy from US$40 per barrel to US$55 per barrel, with effect from November 1, 2011. The special oil gain levy is collected on a quarterly basis. For the years ended December 31, 2012, 2013 and 2014 we incurred approximately Rmb 26.3 billion, Rmb 23.4 billion and Rmb 19.1 billion (US$3.1 billion) for the Special Oil Gain Levy.
 
The current rates of the special oil gain levy are shown in the table below:
 
Realized Oil Price (US$/bbl)

In December 2014, the PRC government has decided to increase the threshold of the special oil gain levy from US$55 per barrel to US$65 per barrel, with effect from January 1, 2015. As international oil prices, the exchange rate of Renminbi and our crude oil production fluctuate, we cannot ascertain the full impact of the Special Oil Gain Levy going forward.
 
Fiscal Regimes for PSC Operations
 
The PRC government encourages foreign participation in offshore oil and gas exploitation. Currently, foreign enterprises can only undertake offshore oil and gas exploitation activities in China after they have entered into a PSC with CNOOC.
 
Under our PSCs, production of crude oil and gas is allocated among us, the foreign partners and the PRC government according to a formula contained in the contracts. Under this formula, a percentage of production under our PSCs is allocated to the PRC government as its share oil.
 
 
55

 
 
When exploitation operations in offshore China are conducted through a PSC, the operator of the oil or gas fields must submit a detailed evaluation report and an overall development program to a joint  management committee established under the PSC upon the discovery of commercially viable oil or gas reserves. The program must be subsequently confirmed by CNOOC and approved by the PRC regulatory authorities before the parties to the PSC begin the commercial development of the oil and gas fields.
 
Under PRC law, only a state-owned company, such as CNOOC, may negotiate a PSC with foreign enterprises. CNOOC assigned to us all of its rights and obligations under then-existing PSCs in 1999 and has undertaken to assign to us its future PSCs except for those relating to CNOOC’s administrative functions as a state-owned oil company.
 
Bidding Process
 
CNOOC and foreign enterprises enter into new PSCs primarily through bidding process organized by CNOOC and direct negotiation. During a typical bidding process, CNOOC determines which blocks are open for bidding and invites foreign enterprises to bid. Potential bidders are required to provide information, including minimum work commitments, exploration expenditures and percentages of share oil payable to the PRC government; and CNOOC evaluates each bid and negotiates a PSC with the successful bidder. CNOOC has agreed to allow us to participate in all negotiations for new PSCs.
 
Terms of PSCs
 
Term of Length. PSCs typically last for 30 years: (1) the exploration period is generally divided into three phases, with three years, two years and two years, respectively. During the exploration period, exploratory and appraisal work is conducted in order to discover petroleum and to enable the parties to determine the commercial viability of any petroleum discovery; (2) the development period begins when the relevant PRC regulatory authorities have approved the overall development program and ends when the design, construction, installation, drilling and related research work for the realization of petroleum production as planned have been completed; and (3) the production period begins when commercial production commences and usually lasts for 15 years for oil and 20 years for natural gas.
 
Minimum Work Commitment. The foreign partners must complete a minimum amount of work during the exploration period, generally including: drilling a minimum number of wildcat(s); acquiring a fixed amount of seismic data; and incurring a minimum amount of exploration expenditures. Foreign partners may be required to pay all exploration costs, which can be recovered according to the production sharing formula after commercial discoveries are made and production begins. Foreign partners are required to relinquish 25% of the contract area, excluding the development and production areas, to CNOOC at the end of each phase of the exploration period and to relinquish all areas, excluding the development areas, production areas and areas under evaluation, to CNOOC at the end of the exploration period.
 
Participating Interests. We have the right to take participating interests up to 51% in any oil or gas field discovered in the contract area and may exercise this right after the foreign partners have made commercially viable discoveries. The foreign partners retain the remaining participating interests.
 
Production Sharing Formula. A chart illustrating the production sharing formula under our PSCs is shown below.

Production tax payable to the PRC government(1)
     
62.5%
 
For the payment of resource tax or recovery:
 
   
1. Resource tax(2) payable to the PRC government
 
   
2. Cost recovery oil(3) allocated according to the following priority:
(1). recovery of current year operating costs by us and foreign partner(s);
 
 
56

 
 
 
   
(2). recovery of current year abandonment costs accrued by us and foreign partner(s) ;
(3). recovery of earlier exploration costs by us and foreign partner(s);
(4). recovery of development costs and deemed interest by us and foreign partner(s) based on participating interests; and
(5). any excess, allocated to the remainder oil.
     
32.5%(4)
 
Remainder oil allocated according to the following formula:
1. (1-X) multiplied by 32.5% represents share oil payable to the PRC government; and
2. X multiplied by 32.5% represents remainder oil distributed according to each partner’s participating interest.

(1)
In this annual report and in our consolidated financial statements included elsewhere in this annual report, references to production tax on oil and gas produced offshore China are the value-added tax set out in our PSCs offshore China.
(2)
For PSCs that came into effect prior to November 1, 2011, instead of resource tax, royalties ( with the rate ranging from 0.0%-12.5% of the annual gross production, depending on the annual gross production of the oilfield) shall be paid to the PRC government.
(3)
The amount of crude oil equivalent to 62.5% of annual gross production minus the amount of crude oil for payment of resource tax shall be cost recovery oil.
(4)
The ratio “X” is agreed in each PSC based on commercial considerations and ranges from 8% to 100%.

 
We calculate and pay oil and gas production tax and royalty (or resource tax) to the PRC government on a monthly basis and make adjustments for any overpayment or underpayment at the end of the year. The foreign partners have the right to either take possession of their allocable remainder oil for sale in the international market, or sell such crude oil to us in the PRC market.
 
Management and Operator. A party will be designated as the operator to undertake the execution of the petroleum operations which includes preparing work programs and budgets, procuring equipment and materials relating to operations, establishing insurance programs, and issuing cash-call notices to the parties to the PSC to raise funds.
 
A joint management committee will be set up to perform supervisory functions. Each of us and the foreign partners has the right to appoint an equal number of representatives to form the joint management committee. We designate the chairman of the committee and the foreign partners as a group designate the vice chairman. The joint management committee has the authority to make decisions on matters including reviewing and approving operational and budgetary plans, determining the commercial viability of each petroleum discovery, reviewing and adopting the overall development program; and approving significant procurements and expenditures as well as insurance coverage.
 
After the foreign partner has fully recovered its exploration and development costs under PSCs in which the foreign partner is the operator, we have the right to take over the operation of the particular oil or gas field. With the consent of the foreign partner, we may also take over the operation before the foreign partner has fully recovered its exploration and development costs.
 
Ownership of Data and Assets. All data, records, samples, vouchers and other original information obtained by foreign partners in the process of exploring, developing and producing offshore petroleum become the property of CNOOC as a state-owned oil company under PRC law. Through CNOOC, we have unlimited and unrestricted access to such information.
 
We and our foreign partners have joint ownership in all of the assets purchased, installed or constructed under the PSCs until either the foreign partners have fully recovered their development costs, or upon the expiration of the production period under the PSCs. After that, CNOOC will assume ownership of all of the assets under the PSCs, and our foreign partners and we retain the exclusive right to use the assets during the production period.
 
Abandonment Costs. Any party to our PSCs shall monthly pay the abandonment cost to the designated bank accounts managed by the operator and jointly owned by the parties in proportion to their participating interests in the development of such oil field and/or gas field in accordance with relevant laws, decrees, and other rules and regulations then existing with respect to the abandonment of offshore facilities of the PRC.

Regulatory Framework Overseas
 
We are subject to other fiscal regimes in the foreign countries and regions where we conduct operations, including Indonesia, Iraq, Australia, Nigeria, Uganda, Argentina, the United States, Canada, United Kingdom and certain other countries. See “Item 4—Information on the Company—Business Overview—Overseas.”
 
In countries including Indonesia, Nigeria, Trinidad and Tobago and certain other countries, we conduct our operations through PSCs. For example, the OML130 block in Nigeria involves a production sharing arrangement. We and the other partners to overseas PSCs are required to bear all exploration, development and operating costs according to our respective participating interests. Exploration, development and operating costs which qualify for recovery can be recovered according to the production sharing formula after commercial discoveries are made and production begins.
 
Our net interest in the PSCs overseas consists of our participating interest in the properties covered under the relevant PSCs, less oil and gas distributed to the local government and/or the domestic market obligation, as applicable.
 
In Australia, the U.S., Canada, United Kingdom, Argentina and certain other countries, we conduct our operations through exploration and production permits, licenses or leases. We, as one of the title owners under these permits, licenses or leases, are required to bear all exploration, development and operating costs together with other co-owners. Once production occurs, a certain percentage of the annual production or revenue will first be distributed to the landowner, in most of cases in the form of royalty, severance tax and other payments, and the rest of the annual production or revenue will be allocated among the co-owners. Exploration, development and operating costs are deductible for the purpose of income tax calculation in accordance with local tax regulations.
 
In Iraq, we operate our project under a technical service contract. We provide technology of developing oil & gas and invest capital to assist the host country to achieve the production goals. According to the technical service contract, we have the rights to recover all the investments and receive remuneration fee as defined in the contract as a return from the incremental production.
 
Taxation
 
Taxes paid and payable by our non-PRC subsidiaries and jointly controlled entities include royalties, duties and export tariffs, as well as taxes levied on petroleum related income, profits and budgeted operating and capital expenditures.
 
Our subsidiaries domiciled outside of the PRC are subject to income tax rates ranging from 10% to 62%.
 
Environmental Regulation
 
Our operations are required to comply with various applicable environmental laws and regulations, including PRC laws and regulations administered by the State Oceanic Administration and national and local environmental protection bureaus for our operations in China. We are also subject to the environmental rules introduced by governments in whose jurisdictions our logistical support facilities are located.
 
Government agencies set national or local environmental protection standards. The relevant State Oceanic Administration and/or environmental protection bureau must approve or review each stage of a project. We must file an environmental impact statement or, in some cases, an environmental impact assessment outline before an approval can be issued. The filing must demonstrate that the project conforms to applicable environmental standards. The State Oceanic Administration and/or relevant environmental protection bureau generally issues approvals and permits for projects using modern pollution control measurement technology.
 
 
58

 
 
The PRC national and local environmental laws and regulations impose fees for the discharge of waste substances above prescribed levels, require the payment of fines for serious violations and provide that the PRC national and local governments, State Oceanic Administration or national and local environmental protection bureaus may at their own discretion close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage.
 
The PRC and overseas environmental laws require offshore petroleum investors to pay abandonment costs. Our financial statements include provisions for costs associated with the dismantlement of oil and gas fields as of December 31, 2012, 2013 and 2014 of approximately Rmb 29,406 million, Rmb 42,351 million and Rmb 52,889 million (US$8,524 million), respectively.

According to the Notice of the National Development and Reform Commission, National Energy Administration, Ministry of Finance, State Administration of Taxation, and State Oceanic Administration on Issuing the Interim Provisions on Administration over the Abandonment and Disposal of Offshore Oil and Gas Production Facilities, investors of the offshore oil and gas fields shall take responsibility for abandonment of the offshore oil and gas production facilities and perform the obligation in relation to environmental protection and ecological restoration, and shall provide and allocate special fund for the aforesaid purpose in accordance with the relevant laws and regulations. The investors include us and the foreign parties to our PSCs.
 
Environmental protection and prevention costs and expenses in connection with the operation of offshore petroleum exploitation are covered either under PSCs, or by us for independent operations. Each platform has its own environmental protection and safety staff responsible for monitoring and operating the environmental protection equipment. However, no assurance can be given that the PRC government will not impose new or stricter regulations which would require additional environmental protection expenditures.
 
We believe that our environmental protection systems and facilities comply with applicable national and local environmental protection regulations.
 
Patents and Trademarks
 
We have licenses to use trademarks which are of value in the conduct of our business. CNOOC is the owner of relevant trademarks. Under the non-exclusive license agreements between CNOOC and us, we have obtained the right to use the trademarks for a nominal consideration.
 
Employees and Employee Benefits
 
During the years ended December 31, 2012, 2013 and 2014, we employed 10,063 persons, 17,553 persons and 21,046 persons, respectively. Of the 21,046 employees we employed as of December 31, 2014, approximately 76.2% were involved in oil exploration, development and production activities, approximately 3.8% were involved in accounting and finance work and the remainder were senior management and others. Part of the workers for the operation of the oil and gas fields, maintenance and ancillary service are hired on a contract basis.
 
We have a union that protects employees’ rights, organizes educational programs, assists in the fulfillment of economic objectives, encourages employee participation in management decisions, and assists in mediating disputes between us and individual employees.
 
We have not been subject to any strikes or other labor disturbances and believe that relations with our employees are good.
 
The total remuneration of employees includes salary, bonuses and allowances. Bonus for any given period is based primarily on individual and our performance. Employees also receive health benefits and other miscellaneous subsidies.
 
We have implemented an occupational health and safety program similar to that employed by other international oil and gas companies. Under this program, we closely monitor and record health and safety incidents and promptly report them to government agencies and organizations. We believe this program is broadly in line with the United States government’s Occupational Safety & Health Administration guidelines.
 
 
59

 
 
 
All full-time employees in the PRC are covered by a government-regulated pension and are entitled to an annual pension at their retirement dates. The PRC government is responsible for the pension liabilities to these retired employees under this government pension plan. The actual pension payable to each retiree is subject to a formula based on the status of the individual pension account, general salary and inflation movements. We are required to make monthly contributions to the government pension plan at rates ranging from 11% to 22% of our employees’ salaries, with each employee contributing 8% of his or her salary for retirement. The contributions vary from region to region.
 
We are required to make contributions to a mandatory provident fund at a rate of 5% of the base salaries for full-time employees in Hong Kong.
 
For further details regarding retirement benefits, see note 31 to our consolidated financial statements included elsewhere in this annual report.
 
As an oil and gas exploration and production company operating in highly competitive markets, we depend in large part on our employees for effective and efficient operations. We devote significant resources to train our employees. During 2014, we held approximately 20,600 training workshops, which were attended by approximately 273,000 person-times of participants. To ensure smooth implementation of our overseas strategy, we have established an international human resources system to attract and retain talent in the international market. In order to enhance the planning and budget control of our labor costs, we have installed target benchmarks in performance appraisals to guide various business units to cut their labor costs and to increase the accuracy of their budgets.
 
ORGANIZATIONAL STRUCTURE
 
CNOOC indirectly owned or controlled an aggregate of approximately 64.44% of our shares as of March 31, 2015. Accordingly, CNOOC continues to be able to exercise all the rights of a controlling shareholder, including electing our directors and voting to amend our articles of association. Although CNOOC has retained a controlling interest in us, the management of our business will be our directors’ responsibility.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS
 
OPERATING RESULTS
 
You should read the following discussion and analysis in conjunction with our consolidated financial statements, selected historical consolidated financial data and operating and reserves data, in each case together with the accompanying notes, contained in this annual report. Certain statements set forth below constitute “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995. See “Forward-Looking Statements.”
 
Overview
 
Our revenues and profitability are largely determined by our production volume and the prices we realize on our crude oil and natural gas, as well as the costs of our exploration and development activities. Although crude oil prices depend on various market factors and have been volatile historically, our total net production volume has increased over the past few years.
 
Factors Affecting Our Results of Operations
 
There are many factors that affect our results of operations and financial condition, mainly including the following:
 
Oil and Gas Prices
 
Substantially all of our revenues are from the sales of oil and natural gas. Therefore, one of the primary factors affecting our revenues is the prices for crude oil and natural gas. Crude oil prices are subject to fluctuations due to market uncertainty and various other factors that are beyond our control, including, but not limited to overall economic conditions, supply and demand dynamics for crude oil and natural gas, political developments, the ability of petroleum producing nations to set and maintain production levels and prices, the price and availability of other energy sources and weather conditions.
 
In addition, our typical contracts with natural gas buyers include provisions for periodic resets and adjustment formulas which may result in selling price fluctuations.
 
In addition to directly affecting our revenues and earnings, declines in crude oil and/or natural gas prices may also result in the write-off of higher cost reserves and other assets. Furthermore, lower crude oil and natural gas prices may reduce the amount of crude oil and natural gas we can produce economically and render existing contracts that we have entered into uneconomical.
 
The following table sets forth our average net realized prices for crude oil and natural gas for the periods indicated:
 
         
Year ended December 31,
 
       
2013
   
2014
 
Average net realized prices:
                 
Crude oil (US$ per bbl)
    110.48       104.60       96.04  
Natural gas (US$ per mcf)
    5.77       5.78       6.44  

Production and Sales Volumes
 
Our revenues are also greatly affected by our production and sales volume as well as our product mix. Our crude oil and natural gas production volumes depend primarily on our ability to keep a high reserve replacement ratio and to develop currently undeveloped reserves in a timely and cost-effective manner.
 
We produce and sell different mixes of crude oil and natural gas, each having different market prices. Therefore, in any given period, our product mix is subject to change, which will also affect our results of operations.

Critical Accounting Policies
 
We prepare our consolidated financial statements in accordance with IFRS issued by the IASB and HKFRS issued by the HKICPA. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of our assets and liabilities, the disclosure of our contingent assets and liabilities as of the date of our financial statements, if any, and the reported amounts of our revenues and expenses during the periods reported. Management makes these estimates and judgments based on historical experience and other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We believe that the following significant accounting policies may involve a higher degree of judgment in the preparation of our consolidated financial statements. For additional discussion of our significant accounting policies, see note 3 to our consolidated financial statements included elsewhere in this annual report.
 
Oil and Gas Properties
 
For oil and gas exploration, we have adopted the successful efforts method of accounting. As a result, we capitalize initial acquisition costs of oil and gas properties. Impairment of initial acquisition costs is recognized as exploration expenses based on exploratory experience and management judgment which includes, but is not limited to, that any dry hole has been drilled on the property; that the carrying amount of the exploration and evaluation asset is unlikely to be recovered in full from successful development or by sale; and that the period during which we have the right to explore in the specific area has expired or will expire in the near future and is not expected to be renewed. Upon discovery of commercial reserves, we transfer acquisition costs to proved properties and capitalize the costs of drilling and equipping successful exploratory wells, all development expenditure on construction, installation or completion of infrastructure facilities such as platforms, pipelines, processing plants and the drilling of development wells, and the building of enhanced recovery facilities, including those renewals and betterments that extend the economic lives of the assets, and the related borrowing costs.
 
The costs incurred in installing enhanced recovery facilities are capitalized together with the development costs of the relevant oil and gas properties. We treat the costs of unsuccessful exploratory wells and all other exploration costs as expenses when incurred. Productive oil and gas properties and other tangible and intangible costs of producing properties are depreciated using the unit-of-production method on a property-by-property basis under which the ratio of produced oil and gas to the estimated remaining proved developed reserves is used to determine the provision of depreciation, depletion and amortization. Common facilities that are built specifically to service production directly attributed to designated oil and gas properties are amortized based on the proved developed reserves of the respective oil and gas properties on a pro-rata basis. Common facilities that are not built specifically to service identified oil and gas properties are depreciated using the straight-line method over their estimated useful lives. Costs associated with significant development projects are not depreciated until commercial production commences and the reserves related to those costs are excluded from the calculation of depreciation. We amortize capitalized acquisition costs of proved properties by the unit-of-production method on a property-by-property basis based on the total estimated proved reserves.
 
 
63

 
 
We recognized the amount of the estimated cost of dismantlement discounted to its present value using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Changes in the estimated timing of dismantlement or dismantlement cost estimates are dealt with prospectively by recording an adjustment to the provision, and a corresponding adjustment to property, plant and equipment. We included the unwinding of the discount on the dismantlement provision as a finance cost.
 
Reserves Estimation
 
Oil and gas properties are depreciated on a unit-of-production basis at a rate calculated by reference to proved reserves. Commercial reserves are determined using estimates of oil in place, recovery factors and future oil prices, the latter having an impact on the proportion of the gross reserves which are attributable to the host government under the terms of the production sharing contracts. The level of estimated commercial reserves is also a key determinant in assessing whether the carrying value of any of the Company’s oil and gas properties has been impaired.
 
Pursuant to the oil and gas reserve estimation requirements under US SEC rules, the Company uses the average, first-day-of-the-month oil price during the 12-month period before the ending date of the period covered by the consolidated financial statements to estimate its proved oil and gas reserves.
 
Impairment of Non-Financial Assets other than Goodwill
 
We make an assessment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, or when there is any indication that an impairment loss previously recognized for an asset in prior years may no longer exist or may have decreased. In any event, we would make an estimate of the asset’s recoverable amount, which is calculated as the higher of the asset’s value in use or its fair value less costs to sell. We recognize an impairment loss only if the carrying amount of an asset exceeds its recoverable amount. We charge an impairment loss to the consolidated statement of profit or loss and other comprehensive income in the period in which it arises. A reversal of an impairment loss is credited to the consolidated statement of profit or loss and other comprehensive income in the period in which it arises.
 
The calculations of recoverable amount of assets require the use of estimates and assumptions. It is reasonably possible that the oil price assumption may change, which may then impact the estimated life of the field and may then require a material adjustment to the carrying value of tangible assets. The Company monitors internal and external indicators of impairment relating to its tangible and intangible assets.
 
Business Combinations and Goodwill

Business combinations are accounted for using the acquisition method. The consideration transferred is measured at acquisition date fair value which is the sum of the acquisition date fair values of assets transferred by the Company, liabilities assumed by the Company to the former owners of the acquiree and the equity interests issued by the Company in exchange for control of the acquiree. For each business combination, the Company elects whether it measures the non-controlling interests in the acquiree either at fair value or at the proportionate share of the acquiree’s identifiable net assets. All other components of non-controlling interests are measured at fair value. Acquisition costs incurred are expensed and included in administrative expenses.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred, the amount recognised for non-controlling interests and any fair value of the Company’s previously held equity interests in the acquiree over the identifiable net assets acquired and liabilities assumed. If the sum of this consideration and other items is lower than the fair value of the net assets of the subsidiary acquired, the difference is recognised in profit or loss as a gain on bargain purchase.
 
 
64

 
 
Joint Arrangements
 
Certain of the Company’s activities are conducted through joint arrangements. Joint arrangements are classified as either a joint operation or joint venture, based on the rights and obligations arising from the contractual obligations between the parties to the arrangement.
 
Joint Operations
 
Some arrangements have been assessed by the Company as joint operations as both parties to the contract are responsible for the assets and obligations in proportion to their respective interest, whether or not the arrangement is structured through a separate vehicle. This evaluation applies to both the Company’s interests in production sharing arrangements and certain jointly-controlled entities.
 
Joint Venture
 
A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement.
 
The Company’s investments in joint ventures are stated in the consolidated statement of financial position at the Company’s share of net assets under the equity method of accounting, less any impairment losses.
 
Fair Value
 
The fair value of financial instruments that are traded in active markets at each reporting date is determined by reference to quoted market prices or dealer price quotations, without any deduction for transaction costs.
 
For financial instruments not traded in an active market, the fair value is determined using appropriate valuation techniques. Such techniques may include using recent arm’s length market transactions; reference to the current fair value of another instrument that is substantially the same; a discounted cash flow analysis or other valuation models.
 
Provisions
 
We recognize a provision when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation provided that a reliable estimate can be made of the amount of the obligation. When the effect of discounting is material, the amount recognized for a provision is the present value at the reporting date of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in finance costs in the consolidated statement of profit or loss and other comprehensive income.
 
We make provisions for dismantlement based on the present value of our future costs expected to be incurred, on a property-by-property basis, in respect of our expected dismantlement and abandonment costs at the end of the related oil exploration and recovery activities.
 
The ultimate dismantlement costs are uncertain and cost estimates can vary in response to many factors including changes to relevant legal requirements, the emergence of new restoration techniques or experience at other production sites. The expected timing and amount of expenditure can also change, for example, in response to changes in reserves or changes in laws and regulations or their interpretation. As a result, there could be significant adjustments to the provisions established which would affect future financial results.
 
 
65

 
 
Deferred Tax
 
Deferred tax is provided, using the liability method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.
 
Deferred tax liabilities are recognized for all taxable temporary differences, except:
 
·  
when the deferred tax liability arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting profit or loss nor taxable profit or loss; and
 
·  
in respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in a joint venture, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.
 
A typical example of transactions that are not business combinations and, at the time of the transaction, affect neither accounting profit or loss nor taxable profit or loss is the acquisition of an asset, such as an exploration license or concession, where no previous activity has taken place, whereby the consideration paid is higher than its tax base.
 
Recognition of Revenue from Oil and Gas Sales and Marketing
 
We recognize revenue when it is probable that the economic benefits will flow to us and when the revenue can be measured reliably. For oil and gas sales, our revenues represent the invoiced value of sales of oil and gas attributable to our interests, net of royalties and obligations to governments and other mineral interest owners. We have adopted a net basis of reporting for royalties and government share oil when we have no legal rights to the underlying reserves. As such, we act as an agent for the relevant governments or royalty holders when we sell the portion of oil and gas on their behalves. Sales are recognized when the significant risks and rewards of ownership of oil and gas have been transferred to customers. Oil and gas lifted and sold by us above or below our participating interests in any PSC result in overlifts and underlifts. We record these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year-end oil prices. Settlement will be in kind or in cash when the liftings are equalized or in cash when production ceases. We enter into gas sales contracts with customers which often contain take-or-pay clauses. Under these contracts, we make a long term supply commitment in return for a commitment from the buyer to pay for minimum quantities, whether or not it takes delivery. These commitments contain protective provisions, such as force majeure provision, and adjustment provisions. If a buyer has a right to get a “make up” delivery at a later date, revenue recognition is deferred. If no such option exists according to the contract terms, revenue is recognized when the take-or-pay penalty is triggered.
 
Our marketing revenues principally represent sales of oil and gas purchased from the foreign partners under our PSCs and revenues from the trading of oil and gas through our subsidiaries. The cost of the oil and gas sold is included in crude oil and product purchases. In addition, our trading activities in North America involves entering into contracts to purchase and sell crude oil, natural gas and other energy commodities, and use derivative contracts, including futures, forwards, swaps and options for hedging and trading purposes (collectively “derivative contracts). Any change in the fair value is also included in marketing revenue.

Calculation of Revenues
 
China
 
We report total revenues, which consist of oil and gas sales, marketing revenues and other income, in our consolidated financial statements included elsewhere in this annual report. With respect to revenues derived from our offshore China operations, oil and gas sales represent gross oil and gas sales less royalties and share oil payable to the PRC government.
 
The gross oil and gas sales consist of our percentage interest in total oil and gas sales, comprised of (i) a 100% interest in our independent oil and gas properties and (ii) our participating interest in the properties covered under our PSCs, less an adjustment for production allocable to foreign partners under our PSCs as reimbursement for exploration costs attributable to our participating interest.
 
Marketing revenues represent our sales of our foreign partners’ oil and gas produced under our PSCs and purchased by us from our foreign partners under such contracts as well as from international oil and gas companies through our wholly owned subsidiary in Singapore. Net marketing revenues represent the marketing revenues net of the cost of purchasing oil and gas from foreign partners and from international oil and gas companies. Our foreign partners have the right to either take possession of their oil and gas for sale in the international market or to sell their oil and gas to us for resale in the PRC market.
 
Other income mainly represents project management fees charged to our foreign partners and handling fees charged to end customers—both fees are recognized when the services are rendered. Reimbursement of insurance claims is recognized when the compensation becomes receivable.
 
Indonesia
 
The oil and gas sales from our subsidiaries in Indonesia consist of our participating interest in the properties covered under the relevant PSCs, less adjustments for oil and gas distributable to the Indonesian government under our Indonesian PSCs and for a domestic market obligation under which the contractor must sell a specified percentage of its crude oil to the local Indonesian market at a reduced price.
 
Iraq
 
The oil sales from Iraq consist of our participating interest in the Missan project.
 
Australia
 
The oil and gas sales from our subsidiaries in Australia consist of our participating interest in the North West Shelf project.
 
Nigeria
 
The oil and gas sales from our subsidiaries in Nigeria consist of our participating interest in the properties covered under the relevant PSCs. We record revenue from oil sales in accordance with the entitlement method. The revenue is calculated based on our participating interest less the rental concession, royalty, and oil and gas distributable to the host country. The royalty rates applicable to deepwater properties are zero.
 
Trinidad and Tobago
 
The oil and gas sales from our subsidiaries in Trinidad and Tobago consist of our participating interest in the properties covered under the relevant PSCs.
 
The U.S. and Canada
 
 
68

 
 
The oil and gas sales from the U.S. consist of our participating interest in the properties of the Eagle Ford project, Niobrara project and properties in the Gulf of Mexico.
 
In respect of oil and gas products derived from Canada, our share of sales is primarily recognized when the ownership of products is transferred at the delivery point of the pipeline. The revenue is calculated net of royalties.
 
United Kingdom
 
The oil and gas sales from the United Kingdom consist of our participating interests in the Buzzard, Scott/Telford/Rochelle and Ettrick/Blackbird properties.
 
Unconsolidated Investees
 
Our share of the oil and gas sales of unconsolidated investees is not included in our revenues, but our share of the profits or losses of these investees is included as part of our share of profits or losses of associates and a joint venture as shown in our consolidated statements of profit or loss and other comprehensive income.
 
2014 versus 2013
 
Consolidated net profit

Our consolidated net profit increased 6.6% to RMB60,199 million (US$9,702.3 million) in 2014 from RMB56,461 million in 2013, primarily as a result of the more strengthened cost control under the recent decreased oil price environment.

In 2014, our net production was 432.5 million BOE (including our interest in equity-accounted investees), representing an increase of 5.1% from 411.7 million BOE in 2013, benefitting from the additional production from the Nexen acquisition in the end of February 2013 and the commencement of production on oil and gas fields in offshore China. The overseas production volume accounted for 37.8% of our total net production volume in 2014, compared with 36.2% in 2013.The decrease of crude and liquids sales was primarily due to the lower realised oil prices in 2014. The increase of gas sales primarily came from the higher prices for sales in domestic China and in East Asian LNG market.

Operating expenses
 
Our operating expenses increased 3.9% to RMB31,180 million (US$5,025.4 million) in 2014 from RMB30,014 million in 2013, and the operating expenses per BOE decreased 1.1% to RMB 75.1 (US$12.11) per BOE in 2014 from RMB75.9 (US$12.55) per BOE in 2013, attributable from effective cost control and steady increase in production. Operating expenses per BOE offshore China decreased 0.8% to RMB60.4 (US$9.73) per BOE in 2014 from RMB60.9 (US$10.06) per BOE in 2013. Overseas operating expenses per BOE decreased 3.2% to RMB102.1 (US$16.46) per BOE in 2014 from RMB105.5 (US$17.43) per BOE in 2013.
 
Taxes other than income tax
 
Our taxes other than income tax decreased 25.7% to RMB 11,842 million (US$ 1,908.6 million) in 2014 from RMB15,937 million in 2013. The decrease was mainly due to the cancellation of accrued mineral resource compensation payment pursuant to the announcement made by Chinese government agencies that did not require separately imposing such fee in offshore China anymore.
 
Exploration expenses
 
Our exploration expenses decreased 32.7% to RMB 11,525 million (US$ 1,857.5 million) in 2014 from RMB17,120 million in 2013, among which dry hole expenses decreased 39.9% to RMB5,686million (US$916.4 million) in 2014 from RMB9,453 million in 2013, due to less uncertain wells which were previously capitalised but written off according to subsequent reserve evaluation. Meanwhile, due to the unfavourable exploration results and overdue leases, some unproved properties of shale gas and oil projects located in the U.S. were written off in 2013. There was no such event in 2014.
 
Depreciation, depletion and amortization
 
Our depreciation, depletion and amortization increased 3.2% to RMB 58,286 million (US$ 9,394.0 million) in 2014 from RMB56,456 million in 2013, primarily as a result of the increased production. Our average depreciation, depletion and amortization per BOE, excluding the dismantlement-related part, increased 0.5% to RMB130.9 (US$ 21.10) per BOE in 2014 from RMB130.3 (US$ 21.53) per BOE in 2013.

The dismantlement-related depreciation, depletion and amortization costs decreased 20.3% to RMB 3,951 million (US$ 636.7 million) in 2014 from RMB4,954 million in 2013, Our average dismantling costs per BOE decreased 24.1% to RMB 9.52 (US$ 1.53) per BOE in 2014 from RMB12.53 (US$2.07) per BOE in 2013,primarily as a result of the decrease in dismantlement asset balance which came from the effect of discounting factor on the present value of asset retirement obligations of producing oil and gas fields.
 
Special Oil Gain Levy
 
Our Special Oil Gain Levy decreased 18.6% to RMB 19,072 million (US$ 3,073.8 million) in 2014 from RMB23,421 million in 2013, primarily as a result of our decreased oil sales in offshore China.
 
Impairment and provision
 
Our impairment and provision was RMB4,120 million(US$664.0 million) in 2014, while in 2013 was credit to impairment of RMB 45 million. In 2014, certain oil and gas properties located in North America and UK North Sea were impaired, which reflected the impact of near term lower price environment. Please refer to Note 15 to the Consolidated Financial Statement of this annual report.
 
Selling and administrative expenses
 
Our selling and administrative expenses decreased 15.9% to RMB 6,613 million (US$ 1,065.8 million) in 2014 from RMB7,859 million in 2013. Such decreases were primarily due to lower commission and consulting payments connected with acquisition and sound effect from enhancing operating efficiency with cost deduction in this year. Our selling and administrative expenses per BOE decreased 20.0% to RMB 15.93 (US$ 2.57) per BOE in 2014 from RMB19.89 (US$3.28) per BOE in 2013.

Finance costs/Interest income
 
Our finance costs increased 38.1% to RMB 4,774 million (US$769.4 million) in 2014 from RMB3,457 million in 2013, primarily due to new issuance of corporate notes which was mainly used to replace short-term loans and the increase in unwinding of discount on provision for dismantlement due to increase in discount rate and obligations contributed from newly developed oil and gas fields in 2014. Our interest income decreased 1.7% to RMB1,073 million (US$ 172.9 million) in 2014 from RMB1,092 million in 2013.
 
Exchange gains, net
 
Our net exchange gains increased 20.2% to RMB1,049 million (US$169.1 million) in 2014 from RMB873 million in 2013, primarily as a result of GBP depreciating against US dollar.
 
Investment income
 
Our investment income increased 2.8% to RMB 2,684 million (US$ 432.6 million) in 2014 from RMB2,611 million in 2013, primarily attributable to the increase in return on corporate wealth management products and  money market funds held by the company.
 
Share of profits of associates/a joint venture
 
Our share of profits of associates/a joint venture increased 12.4% to RMB1,006 million (US$162.1 million) in 2014 from RMB895 million in 2013, primarily attributable to the increase in profitability of associates.
 
Income tax expense
 
Our income tax expense decreased 8.5% to RMB 22,314million (US$ 3,596.4 million) in 2014 from RMB24,390 million in 2013, and the effective tax rate decreased to 27.0% in 2014 from 30.2% in 2013. The decrease in effective tax rate was mainly attributable to further recognized deferred tax assets for oil sands project in Canada.

 
2013 versus 2012
 
Consolidated net profit

Our consolidated net profit decreased 11.4% to Rmb56,461 million in 2013 from Rmb63,691 million in 2012, primarily as a result of the comprehensive impact of the decreased oil price and the increased costs.

The increase of our oil and gas sales was primarily due to the significant increase of production attributable from the Nexen acquisition.

In 2013, our net production was 411.7 million BOE (including our interest in equity-accounted investees), representing an increase of 20.2% from 342.4 million BOE in 2012, benefitting from the addition from the Nexen acquisition and the increased production of shale oil and gas in North America and technical service contract in Iraq. The overseas production volume accounted for 36.2% of our total net production volume in 2013, compared with 22.0% in 2012.

Operating expenses
 
Our operating expenses increased 40.0% to Rmb30,014 million in 2013 from Rmb21,445 million in 2012, and the operating expenses per BOE increased 15.2% to Rmb75.9 per BOE in 2013 from Rmb65.9 per BOE in 2012, primarily as a result of the addition from the Nexen acquisition. Operating expenses per BOE offshore China increased 5.4% to Rmb60.9 per BOE in 2013 from Rmb57.8 per BOE in 2012. Overseas operating expenses per BOE increased 2.9% to Rmb105.5 per BOE in 2013 from Rmb102.5 per BOE in 2012.
 
Taxes other than income tax
 
Our taxes other than income tax increased 2.0% to Rmb15,937 million in 2013 from Rmb15,632 million in 2012, primarily as a result of the comprehensive impact of changes in oil and gas sales in offshore China and overseas.
 
Exploration expenses
 
Our exploration expenses increased 89.3% to Rmb17,120 million in 2013 from Rmb9,043 million in 2012, primarily as a result of the addition from the Nexen acquisition, and our continuous enhancement of exploratory activities in offshore China, especially in deepwater. Meanwhile, due to the unfavourable exploration appraisal results and some overdue land leasehold contracts, some of the unproved properties of shale oil and gas project located in North America were written off in 2013. Nexen focuses on opportunities in the deepwater of U.S. Gulf of Mexico and U.K. North Sea, which are deepwater areas with good exploration prospect. Meanwhile, in the recent two years, our continuing efforts in exploration in offshore China has led to a series of important reserves discoveries and upgrades, but also resulted in continuing increased exploration expenses. Dry hole expenses increased 78.5% to Rmb7,140 million in 2013 from Rmb3,999 million in 2012, including costs of some uncertain wells that were capitalized previously and written off according to appraisal result.
 
Depreciation, depletion and amortization
 
Our depreciation, depletion and amortization increased 71.6% to Rmb56,456 million in 2013 from Rmb32,903 million in 2012, primarily as a result of the addition from the Nexen acquisition, the increased production of shale oil and gas in North America and technical service contract in Iraq and the commencement of production on new oil and gas fields in offshore China. Our average depreciation, depletion and amortization per BOE, excluding the dismantlement-related depreciation, depletion and amortization, increased 41.5% to Rmb130.3 per BOE in 2013 from Rmb92.1 per BOE in 2012. These increases were mainly attributable to the increased production proportion from oil sands, shale oil and gas and technical service contract overseas, which have higher depreciation, depletion and amortization rate. In addition, the increased proportion of production on new oil and gas fields in offshore China in recent year, which were developed under the environment of increasing prices of raw materials and services over the past few years, also contributed to the increase of depreciation, depletion and amortization per BOE.
 
 
72

 
 
The dismantlement-related depreciation, depletion and amortization costs increased 68.2% to Rmb4,954 million in 2013 from Rmb2,946 million in 2012, primarily as a result of the addition from the Nexen acquisition. Our average dismantling costs per BOE increased 38.4% to Rmb12.53 per BOE in 2013 from Rmb9.06 per BOE in 2012.
 
Special Oil Gain Levy
 
Our Special Oil Gain Levy decreased 10.9% to Rmb23,421 million in 2013 from Rmb26,293 million in 2012, primarily as a result of our decreased oil sales in offshore China.
 
Selling and administrative expenses
 
Our selling and administrative expenses increased 132.7% to Rmb7,859 million in 2013 from Rmb3,377 million in 2012. Such increases were primarily due to the addition from the Nexen acquisition and the related commissions and consulting expenses. Our selling and administrative expenses per BOE increased 91.6% to Rmb19.89 per BOE in 2013 from Rmb10.38 per BOE in 2012.
 
Finance costs/Interest income
 
Our finance costs increased 115.7% to Rmb3,457 million in 2013 from Rmb1,603 million in 2012, primarily due to the addition from the Nexen acquisition and capital demand increase from expansion in overseas investment as well as the increase in unwinding of discount on provision for dismantlement due to commencement of production on new oil and gas fields. Our interest income increased 9.0% to Rmb1,092 million in 2013 from Rmb1,002 million in 2012, primarily due to the increased effective rate of return from increased time deposits.
 
Exchange gains, net
 
Our net exchange gains increased 143.2% to Rmb873 million in 2013 from Rmb359 million in 2012, primarily as a result of the further appreciation of Renminbi/US dollars and Renminbi/HK dollars.
 
Investment income
 
Our investment income increased 9.2% to Rmb2,611 million in 2013 from Rmb2,392 million in 2012, primarily attributable to the increase in aggregate corporate wealth management products under the condition that the products and portfolios are of good liquidity and low risk.
 
Share of profits of associates/a joint venture
 
Our share of profits of associates/a joint venture was Rmb895 million in 2013, while in 2012 we shared losses of Rmb27 million, primarily attributable to the increased profitability of overall assets contributed by the downstream refinery which was acquired by Bridas in the second half of 2012.
 
Income tax expense
 
Our income tax expense decreased 7.9% to Rmb24,390 million in 2013 from Rmb26,481 million in 2012, and the effective tax rate increased to 30.2% in 2013 from 29.4% in 2012. The increase in effective tax rate was mainly attributable to the Nexen acquisition, partially offset by the increased tax credits arising from certain qualified capital expenditure in Nigeria along with the development of Egina oilfield of OML130 project.

In 2014, our capital expenditure (excluding acquisition) increased 20.0% to RMB95,673 million (US$15,419.7 million) from 2013, primarily as a result of the increase in exploration activities and the development of projects under construction. Our development expenditures in 2014 were primarily related to the capital expenditures of Nexen, the development of the OML130 project, as well as the expenses incurred for improving recovery factors of the oilfields in production. The Company has no significant acquisition during the year.

In addition, our cash used in investing activities was also attributable to purchase of available-for-sale financial assets of RMB105,718 million (US$17,038.6 million). Our cash generated from investing activities was mainly from the proceeds from the sales of available-for-sale financial assets in the amount of RMB102,587 million (US$16,534.0 million). Our time deposits with maturity of more than three months decreased by RMB3,383 million (US$545.2 million) in 2014.

Cash Used in / Generated from Financing Activities
 
In 2014, the cash inflow from financing activities was mainly due to the proceeds of bank borrowings of RMB12,789 million (US$2,061.2 million) and RMB24,578 million (US$3,961.3 million) from the issuance of guaranteed notes, partially offset by the cash outflow of the distribution of dividends of RMB20,216 million (US$3,258.2 million) and the repayment of bank loans of RMB32,523 million (US$5,241.8 million).

At the end of 2014, our total interest-bearing outstanding debt was RMB136,563 million (US$22,010.0 million), compared to RMB131,852 million at the end of 2013. The increase in debt in 2014 was primarily attributable to the issuance of guaranteed notes of US$4 billion and the decrease of short-term bank loans. Our gearing ratio, which is defined as interest-bearing debts divided by the sum of interest-bearing debts plus equity, was 26.5%, lower than that of 27.8% in 2013.

We have debt service obligations consisting of principal and interest payments on our outstanding indebtedness. The following table summarizes the maturities of our long-term debt (including the current portion) outstanding as of December 31, 2014.

In April 2014, we, through CNOOC Nexen Finance (2014) ULC, our wholly owned subsidiary, issued US$1,250 million 1.625% guaranteed notes due 2017, US$2,250 million 4.250% guaranteed notes due 2024, and US$500 million 4.875% guaranteed notes due 2044. The obligation of CNOOC Nexen Finance (2014) ULC in respect of the notes are unconditionally and irrevocably guaranteed by us. The net proceeds of this notes offering were used to in part to repay all or part of the outstanding borrowings of our wholly-owned subsidiary Nexen Energy ULC under the US$2.0 billion facility agreement dated February 15, 2014. The remaining proceeds were used for general corporate purposes.

As of December 31, 2014, we had total foreign currency debt of US$21,367 million, all of which is in U.S. dollars. As of March 31, 2015, we had total foreign currency debt of US$22,441 million, all of which is in U.S. dollars.
 
As of December 31, 2014, we had unutilized banking facilities amounting to approximately Rmb 63,623 million (US$10,254 million) as compared to Rmb 56,440 million as of December 31, 2013.
 
In 2012, 2013 and 2014, we paid dividends totaling Rmb 15,635.1 million, Rmb 20,226 million and Rmb 20,216 million (US$3,258 million) (before PRC withholding tax deducted), respectively. The payment and the amount of any dividends in the future will depend on our results of operations, cash flows, financial condition, the payment by our subsidiaries of cash dividends to us, future prospects and other factors which our directors may consider relevant. The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future.
 
We believe our future cash flows from operations, borrowing capacity and funds raised from our debt offerings will be sufficient to fund planned capital expenditures and investments, debt maturities and working capital requirements through at least 2015. However, our ability to obtain adequate financing to satisfy our capital expenditures and debt service requirements may be limited by our financial condition and results of operations and the liquidity of international and domestic financial markets. See “Item 3—Key Information—Risk Factors—Risks Relating to Our Operations—Our future prospects largely depend on our capital expenditures, which are subject to various risks.”
 
Capital Expenditures
 
For 2015, we have budgeted approximately Rmb 70.4 billion for capital expenditures for exploration and development. The following table sets forth actual or budgeted capital expenditures on an accrual basis for the periods indicated.

In addition to the budgeted development and exploration expenditures relating to the oil and gas properties described above, we may make additional capital expenditures and investments consistent with our business strategy. See “Item 4—Information on the Company—Business Overview—Business Strategy.” We expect to fund our capital expenditures with our cash flows from operations and external financing.

Our ability to maintain and grow our revenues, profit and cash flows depends upon continued capital spending. Generally, we adjust our capital expenditure and investment budget on an annual basis. Our capital expenditure plans are subject to a number of risks, contingencies and other factors, some of which are beyond our control. Therefore, our actual future capital expenditures and investments will likely be different from our current planned amounts, and such differences may be significant. See “Item 3—Key Information—Risk Factors—Risks Relating to Our Operations—Our future prospects largely depend on our capital expenditures, which are subject to various risks.”

Holding Company Structure
 
We are a holding company. Our entire oil and gas exploration, development, production and sales business in the PRC is owned and conducted by CNOOC China Limited, our wholly owned subsidiary in the PRC. Our entire oil and gas exploration, development and production business outside the PRC is owned and conducted by CNOOC International Limited, our wholly owned subsidiary incorporated in the British Virgin Islands, or directly owned by our company itself. International sales of crude oil and natural gas are conducted by China Offshore Oil (Singapore) International Pte Ltd, our wholly owned subsidiary incorporated in Singapore. Nexen Energy ULC, a wholly-owned subsidiary of the Company, located in Canada, sells its crude oil and synthetic oil to international markets separately. Accordingly, our future cash flows will consist principally of dividends from our subsidiaries. The subsidiaries’ ability to pay dividends to us is subject to various restrictions, including legal restrictions in their jurisdictions of incorporation. For example, legal restrictions in the PRC permit payment of dividends only out of profit determined in accordance with PRC accounting standards and regulations. In addition, under PRC law, CNOOC China Limited should set aside a portion of its profit each year to fund certain reserve funds. These reserves are not distributable as cash dividends.
 
Inflation/Deflation
 
According to the China Statistical Bureau, as represented by the general consumer price index, China experienced an overall inflation rate of 2.6%, 2.6% and 2.0% in 2012, 2013 and 2014, respectively. Neither deflation nor inflation has had a significant impact on our results of operations in the respective years.
 
Impact of Recently Issued Accounting Standards
 
IFRS and HKFRS
 
We have adopted the IFRS as issued by the IASB since January 1, 2008. Therefore, our consolidated financial statements for 2014 have been prepared in due compliance with both IFRS and HKFRS. The accounting policies adopted are consisted with those of the year ended 31 December 2013, except for the first time adoption of the amendments to IFRS/HKFRS and the new interpretation effective for the Group's financial year beginning on 1 January 2014. The adoption of those amendments and interpretation upon their effective dates has had no material impact on the accounting policies, the disclosures or the amounts recognized in the consolidated financial statements of the Group.

TREND INFORMATION
 
In 2015, the outlook for the global economy will continue to face relatively high uncertainty. International oil prices are expected to continue at low levels for a period of time, and the Company’s operations will be faced with significant challenges. As a result, the Company will further promote all measures for realizing the “Year of Efficiency and Quality” and make all efforts to reduce costs and raise efficiency, in order to meet all targets for production and operation.

Prices for crude oil may fluctuate widely in response to relatively minor changes in the supply and demand for oil, market uncertainty and various other factors that are beyond our control.

We plan to increase our reserves and production through drill bits and value-driven acquisitions. We will continue to concentrate independent exploration efforts on major operating areas, especially in offshore China. In the meantime, we will continue to enter into PSCs with foreign partners to lower capital requirements and exploration risks.

We plan to capitalize on the growth potential of the PRC natural gas market, and continue to explore and develop natural gas fields. In the event that we invest in businesses and geographic areas where we have limited experience and expertise, we plan to structure our investments in the form of alliances or partnerships with partners possessing the relevant experience and expertise.

In 2014, the large-sized deepwater gas field Liwan 3-1 in deepwater South China Sea has commenced production and our natural gas production continued to increase.

We will continue to maintain our prudent financial policy. As an essential part of our corporate culture, we continue to promote the cost consciousness among both our management team and other employees. Aiming to control production cost, we plan to actively promote the regional development of oil and gas field groups and to apply up-to-date offshore engineering, drilling and production technologies to our operations. We intend to maintain our financial strength by managing key measures such as capital expenditures, cash flows and costs per BOE. We also intend to actively manage our account receivables and inventories to enhance liquidity and improve profitability. We will continue to monitor our foreign currency denominated assets and debts and to manage exposure to foreign exchange rate fluctuations.
 
For 2015, we have budgeted Rmb 70 billion to 80 billion for capital expenditures for exploration and development.

Other than as disclosed in the paragraphs above under Item 5.D, we are not aware of any trends that are reasonably likely to have a material effect on our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information not necessarily to be indicative of future operating results or financial conditions. You are urged to read the forward-looking statements contained elsewhere in this annual report, the cautionary statement on page 9 and the Risk factors on pages 14, which describe the risks and uncertainties that may cause actual results and developments to differ materially from those expressed or implied by these forward-looking statements. The Company provides no commitment to update the forward-looking statements or to publish financial projections for forward-looking statements in the future.

Summary of Significant Differences in Corporate Governance Practices for Purposes of Section 303A.11 of the New York Stock Exchange Listed Company Manual
 
We are incorporated under the laws of Hong Kong. The principal trading market for our shares is the Hong Kong Stock Exchange. In addition, because our shares are registered with the United States Securities and Exchange Commission and are listed on the New York Stock Exchange, or the NYSE, we are subject to certain corporate governance requirements. However, many of the corporate governance rules in the NYSE Listed Company Manual, or the NYSE Standards, do not apply to us as a “foreign private issuer” and we are permitted to follow the corporate governance practices in Hong Kong in lieu of most corporate governance standards contained in the NYSE Standards. Section 303A.11 of the NYSE Standards requires NYSE-listed foreign private issuers to describe the significant differences between their corporate governance practices and the corporate governance standards applicable to U.S. domestic companies listed on the NYSE, or U.S. domestic issuers. We set forth below a brief summary of such significant differences.
 
1. Board and Committee Independence
 
While NYSE Standards require U.S. domestic issuers to have a majority of independent directors, we are not subject to this requirement. Four of our ten directors are independent non-executive directors.
 
NYSE Standards require U.S. domestic issuers to schedule regular executive sessions of non-management directors, or regular executive sessions of independent directors only. NYSE Standards also require that, if a U.S. domestic issuer chooses to hold regular meetings of all non-management directors, it should hold an executive session at least once a year to be attended by only independent directors. We are not subject to such requirements and our independent directors attend all board meetings where possible. We also schedule meetings between our chairman and our independent non-executive directors.
 
NYSE Standards require U.S. domestic issuers to disclose a method for interested parties to communicate directly with the presiding director of the executive sessions, or with the non-management or independent directors as a group. We are not subject to such requirement and we have not adopted such a method yet.
 
2. Audit Committee
 
If an audit committee member simultaneously serves on the audit committees of more than three public companies, and the listed company does not limit the number of audit committees on which its audit committee members serve to three or less, then in each case, the board of directors of the U.S. domestic issuer is required to determine that such simultaneous service would not impair the ability of such member to effectively serve on its audit committee and disclose such determination on or through the U.S. domestic issuer’s website or in its annual proxy statement or annual report. We are not subject to such requirement and we have not addressed this in our audit committee charter.
 
NYSE Standards require audit committees of U.S. domestic issuers to discuss guidelines and policies that govern the process by which risk assessment and risk management are handled and include such responsibilities in their audit committee charters. We are not subject to such requirement and our audit committee charter does not have such provision. Our audit committee charter only provides that our audit committee shall review with our external auditors and the general managers of internal audit and risk management departments the scope, adequacy and effectiveness of our corporate accounting and financial controls, internal control and risk management systems, and any related significant findings regarding risks or exposures and consider recommendations for improvement of such controls.
 
NYSE Standards require audit committees of U.S. domestic issuers to produce an audit committee report annually and include such report in their annual proxy statements. We are not subject to such requirement and we have not addressed this in our audit committee charter.
 
 
88

 
 
3. Remuneration Committee
 
NYSE Standards require U.S. domestic issuers to have a compensation committee composed entirely of independent directors. We are not subject to such requirement and have a remuneration committee that consists of two independent non-executive directors and one non-executive director. NYSE Standards also require the board of directors of U.S. domestic issuers to consider additional factors in evaluating the independence of compensation committee members, including the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by the issuer to such director and whether such director is affiliated with the issuer, a subsidiary of the issuer or an affiliate of a subsidiary of the issuer. We are not subject to such requirement and we have not considered such additional factors in evaluating the independence of compensation committee members.
 
NYSE Standards require U.S. domestic issuers to address in their compensation committee charters matters regarding committee member removal and committee structure and operations (including authority to delegate to subcommittees). We are not subject to such requirement and we have not addressed this in our remuneration committee charter.
 
NYSE Standards require compensation committees of U.S. domestic issuers to produce a compensation committee report annually and include such report in their annual proxy statements or annual reports on Form 10-K. We are not subject to such requirement and we have not addressed this in our remuneration committee charter. We disclose the amounts of compensation of our directors on a named basis, senior management by band and the five highest paid employees in our annual reports according to the requirements of the Hong Kong Stock Exchange Listing Rules.
 
NYSE Standards require compensation committees of U.S. domestic issuers may, in its sole discretion, retain or obtain the advice of compensation consultants or other advisers, only after taking into consideration all factors relevant to such advisers’ independence from management, including the various factors as specified in the NYSE Standards, and issuers must provide funding for the retention of such advisers. Also, compensation committees shall be directly responsible for the appointment, compensation and oversight of the advisers they retain. We are not subject to these requirements and we have not applied such requirements and addressed them in our remuneration committee charter.
 
4. Nomination Committee
 
While NYSE Standards require U.S. domestic issuers to have only independent directors on their nomination committee, we are not subject to such requirement and our nomination committee consists of two independent non-executive directors and one non-executive director.
 
NYSE Standards require U.S. domestic issuers to address in their nomination committee charters matters regarding committee member removal and committee structure and operations (including authority to delegate to subcommittees). We are not subject to such requirement and we have not addressed this in our nomination committee charter.
 
5. Corporate Governance Guidelines
 
NYSE Standards require U.S. domestic issuers to adopt and disclose corporate governance guidelines.

Overview

Since CNOOC indirectly owns an aggregate of approximately 64.44% of our outstanding shares, some of these transactions constitute connected transactions under the Hong Kong Stock Exchange Listing Rules, and are regulated by the Hong Kong Stock Exchange.

·
Sales and purchase of goods and services;
 
·
Purchases of assets, goods and services;

Leases of assets; and

These transactions are conducted in the ordinary course of business.
 
Categories of Continuing Connected Transactions

As we are controlled by CNOOC, transactions with CNOOC, its subsidiaries and associates are deemed to be related party transactions. We entered into a comprehensive framework agreement with CNOOC on November 6, 2013 for the provision (1) by us and/or our associates and (2) by CNOOC and/or its associates to us, of a range of products and services which may be required and requested from time to time by either party and/or its associates in respect of the continuing connected transactions. The comprehensive framework agreement is substantially on the same terms as the terms contained in the comprehensive framework agreements entered into by us on November 1, 2010. The term of the comprehensive framework agreement is for a period of three years from January 1, 2014. The continuing connected transactions and relevant annual caps were approved by our independent shareholders on November 27, 2013. The approved continuing connected transactions are as follows:

Pricing principles

The continuing connected transactions are based on negotiations with CNOOC and/or its associates on normal commercial terms, or on terms no less favorable than those available to us from independent third parties, under prevailing local market conditions, including considerations such as volume of sales, length of contracts, package of services, overall customer relationship and other market factors.

For continuing connected transactions referred to in paragraphs 1(a) to 1(d) above provided by CNOOC and/or its associates to us and paragraph 2 above provided by us to CNOOC and/or its associates, based on the above pricing principles, such services must be charged in accordance with the following pricing mechanism and in the following sequential order:

 
(i)
state-prescribed prices; or
 
(ii)
where there is no state-prescribed price, market prices, including the local, national or international market prices; or
 
(iii)
when neither (i) nor (ii) is applicable, the cost of CNOOC and/or its associates or us and /or our associates for providing the relevant service (including the cost of sourcing or purchasing from third parties) plus a margin of not more than 10%, before any applicable taxes.

Based on the above pricing principles, the continuing connected transactions referred to in paragraph 1(e) above provided by CNOOC and/or its associates to us are at market prices on normal commercial terms which are calculated on a daily basis.

Based on the above pricing principles, the continuing connected transactions referred to in paragraphs 3(a) above provided by us to CNOOC and/or its associates are at state-prescribed prices or local, national or international market prices and on normal commercial terms.

Based on the above pricing principles, the continuing connected transactions referred to in paragraphs 3(b) above provided by us to CNOOC and/or its associates are at state-prescribed prices or local, national or international market prices and on normal commercial terms, which are subject to adjustment in accordance with movements in international oil prices as well as other factors such as the term of the sales agreement and the length of the relevant pipeline.
 
Disclosure and/or Independent Shareholders’ Approval Requirements
 
Under the Hong Kong Stock Exchange Listing Rules, the following categories of continuing connected transactions are exempted from the independent shareholders’ approval requirement but are subject to the announcement, annual report and annual review requirements set out in the Hong Kong Stock Exchange Listing Rules, because each of the percentage ratios for these categories under the Hong Kong Stock Exchange Listing Rules (other than the profits ratio) , where applicable, is expected to be less than 5% on an annual basis:

We confirmed that the annual amount of each category of the non-exempt continuing connected transactions for the year ended December 31, 2014 did not exceed the applicable annual caps; and we have complied with other relevant provisions of the Hong Kong Stock Exchange Listing Rules in relation to each category of the non-exempt continuing connected transactions.
 
Transactions with CNOOC Finance Corporation Limited
 
On October 14, 2008, we entered into a financial services framework agreement with CNOOC Finance Corporation Limited, our 31.8% owned associate and a subsidiary of CNOOC, pursuant to which CNOOC Finance Corporation Limited provides us with settlement, depository, discounting, loans and entrustment loans services. On August 20, 2010, we entered into a renewal agreement with CNOOC Finance Corporation Limited to renew the financial services framework agreement.
 
As the financial services framework agreement (as renewed on August 20, 2010) entered into by us and CNOOC Finance Corporation Limited expired on December 31, 2013, we entered into a new renewal agreement with CNOOC Finance Corporation Limited on November 27, 2013 to further renew the financial services framework agreement for another three years from January 1, 2014 to December 31, 2016. According to the renewal agreement dated November 27, 2013, the maximum daily outstanding balance of deposits (including accrued interests)(excluding funds placed for the purpose of extending entrustment loans pursuant to the entrustment loan services) should not exceed Rmb 22 billion for the period from January 1, 2014 to December 31, 2016. The depository services were exempted from independent shareholders’ approval requirements and the settlement, discounting, loans and entrustment loans services were exempted from all the connected transaction requirements under the Hong Kong Stock Exchange Listing Rules.
 
We confirmed that the maximum daily outstanding balance of deposits (including accrued interests but excluding funds placed for the purpose of extending entrustment loans pursuant to the entrustment loan services) we placed with CNOOC Finance Corporation Limited did not exceed Rmb 22 billion from January 1, 2014 to December 31, 2014.

Coalbed Methane Resources Exploration and Development Cooperation Agreement with China United Coalbed Methane Corporation Limited
 
On August 3, 2012, CNOOC China Limited, our wholly-owned subsidiary, entered into the Coalbed Methane Resources Exploration and Development Cooperation Agreement (“Cooperation Agreement”) with China United Coalbed Methane Corporation Limited (“CUCBM”) in connection with the exploration, development, production and sale of Coalbed Methane (“CBM”) and CBM products within the contract areas (as defined in the Cooperation Agreement). The term of the Cooperation Agreement commences on the effective date and expires on the later of (i) 30 years from the effective date of the Cooperation Agreement, and (ii) the end of the production period of the last CBM field (as defined in the Cooperation Agreement) in the contract areas, unless otherwise agreed by CNOOC China Limited and CUCBM. The Cooperation Agreement and the transactions contemplated thereunder were approved by our independent shareholders on August 21, 2012. As at the date of the Cooperation Agreement, CNOOC China Limited expected to incur total expenses of Rmb 9,933.3 million (being (1) Rmb 9,713.3 million for the initial three years of the five years exploration period, plus (2) the minimum exploration costs of Rmb 220 million as required under the applicable PRC laws and regulations for the remaining two years of the exploration period). CUCBM is a connected person of us, hence the Cooperation Agreement constitutes a connected transaction of us under the Hong Kong Stock Exchange Listing Rules.
 
As CUCBM is unable to fulfill its obligations under the Cooperation Agreement in respect of four CBM blocks (the “Relevant Blocks”) which formed part of the contract areas (as defined in the Cooperation Agreement), CNOOC China Limited and CUCBM entered into a supplemental agreement on October 10, 2013, pursuant to which (i) the Relevant Blocks were excluded from the contract areas; and (ii) CUCBM would indemnify in full CNOOC China Limited against any related loss, the amount of which would be determined by a third party appraising firm appointed by both parties. CNOOC China Limited and CUCBM have reached an agreement on the compensation for the losses of CNOOC China Limited related to such Relevant Blocks.As the Relevant Blocks were still at preliminary exploration stage, no revenue was generated and it is expected that the exclusion of the Relevant Blocks from the contract areas will not materially affect the expected profit in relation to the Cooperation Agreement.
 
Borrowings from CNOOC
 
In September 2014, CNOOC provided CNOOC International Limited, a wholly-owned subsidiary of us a five-year uncommitted revolving loan facility for general purposes, with the principal amount of US$135 million of 0.95% per annum. As at March 31, 2015, the withdrawal amount of the loan was US$130 million; In December 2014, CNOOC provided us a five-year uncommitted revolving loan facility for general purposes, with the principal amount of US$600 million of 0.95% per annum. As at March 31, 2015, the withdrawal amount of the loan was US$564 million. All the loans above are unsecured.

Dividend Distribution Policy
 
The payment of any future dividends will be determined by our Board, subject to shareholders’ approval for all dividends other than interim dividends, based upon, among other things, our future earnings, capital requirements, financial conditions, future prospects and other factors which our Board may consider relevant. Our ability to pay dividends will also depend on the cash flows determined by the dividends, if any, received by us from our subsidiaries and associates. Holders of our shares will be entitled to receive such dividends declared by our Board pro rata according to the amounts paid up or credited as paid up on the shares. Subject to the factors described above, we currently intend to pursue a dividend policy consistent with other international oil and gas exploration and production companies.
 
Dividends may be paid only out of our distributable profits as permitted under Hong Kong law, which does not restrict the payment of dividends to nonresident holders of our securities. To the extent profits are distributed as dividends, such portion of profits will not be available to be reinvested in our operations.
 
Holders of our ADSs will be entitled to receive dividends, subject to the terms of the deposit agreement, to the same extent as holders of our shares, less the fees and expenses payable under the deposit agreement and withholding taxes of 10%. Cash dividends will be paid to the depositary in Hong Kong dollars and will be converted by the depositary into U.S. dollars and paid to holders of ADSs. Stock dividends, if any, will be distributed to the depositary and will be distributed by the depositary, in the form of additional ADSs, to holders of the ADSs.
 
In 2012, we declared and paid dividends totaling Rmb 15,635 million. In 2013, we declared and paid dividends totaling Rmb 20,226 million. In 2014, we declared and paid dividends totaling Rmb 20,216 million (US$3,258 million). The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future.
 
Substantially all our dividend payments result from dividends paid to us by CNOOC China Limited. CNOOC China Limited must follow the laws and regulations of the PRC and its articles of association in determining its dividends. As a wholly foreign owned enterprise in China, CNOOC China Limited has to provide for a reserve fund and staff and workers’ bonus and welfare fund, each of which is appropriated from net profit after taxation but before dividend distribution according to the prevailing accounting rules and regulations in the PRC. CNOOC China Limited is required to allocate at least 10% of its net profit to the reserve fund until the balance of this fund has reached 50% of its registered capital, which amount was reached in 2009. Appropriations to the staff and workers’ bonus and welfare fund, which are determined at the discretion of the directors of CNOOC China Limited, are charged to expense as incurred in our consolidated financial statements, which were prepared under IFRS. In accordance with the “Temporary Regulation for Safety Expense Financial Management of High Risk Industry” and the implementation guidance issued by the Ministry of Finance of the PRC, a safety fund has been accrued for our oil and gas exploration and production activities within the PRC. The accrued safety fund will be utilized for improving the safety conditions of our production. Included in other reserves was a provision for safety fund under the PRC regulation amounting to Rmb 691.7 million (US$111.5 million) in 2014, which was Rmb 645.0 million in 2013. None of the contributions of CNOOC China Limited to these statutory funds may be used for dividend purposes.
 
For the years ended December 31, 2012, 2013 and 2014, CNOOC China Limited made the following appropriations to the statutory reserves:

Contingencies
 
(a)
With respect to Penglai 19-3 Oilfield Oil Spill Accidents (please refer to the Annual Reports and/or Interim Reports of the Company issued in or after 2012 for the background information), the Company is of the view that the Company’s obligations, if any, arising from the above mentioned accidents shall be determined in accordance with relevant laws and regulations, the production sharing contract ( the "PSC") and related agreements, among others. Based on evaluations performed as of the date of the consolidated financial statements authorized for issuance, the Company believes that it is not possible to determine provisions, if any, for the Company’s obligation determined in the future arising from the above mentioned accidents in the consolidated financial statements. The financial impact of such oil spill accidents on the Company is still uncertain, and the Company has not made any provision for the accidents in the consolidated financial statements.

(b)
On 11 October 2012, the Company was served with a purported class action complaint filed by Sam Sinay, individually and on behalf of all others similarly situated (the “Plaintiff”) in the Unites States District Court for the Southern District of New York (the “Trial Court”) (the foregoing legal action is therein below referred as the “Complaint”). The Complaint was lodged against the Company and certain of its officers, which alleged that during the period between 27 January 2011 and 16 September 2011, the Company made materially false and misleading statements regarding its business and financial results and the oil spill accidents occurred at the Penglai 19-3 oilfield.

On 21 December 2012, the Company filed a motion to dismiss the Complaint in the Trial Court.

On 4 April 2013, the judge of the Trial Court approved the Plaintiff’s voluntarily dismissal, without prejudice, to its claims against the officers of the Company.

On 6 May 2013, the judge of the Trial Court granted the Company’s motion to dismiss in the entirety with prejudice. On 5 June 2013, the Plaintiff (i.e. the Appellant) appealed to the United States Court of Appeals for the Second Circuit (the “Court of Appeals”). On 3 February 2014, the Court of Appeals issued a summary order which found the Appellant’s argument without merit and affirmed the Trail Court’s judgment. After the issuance of the summary order, the Appellant was able to appeal to the Supreme Court of the United States within 90 days (namely, on or before 5 May 2014, New York time) (the “Appeal Period”). The Appellant did not appeal within the Appeal Period. In accordance with the laws of the United States, all the claims brought by the Appellant at the Trial Court and the Court of Appeals are dismissed in their entirety.

(c)
As a Chinese Resident Enterprise, the Company may be liable to pay taxes on the deemed interest income for the funding provided to its overseas subsidiaries starting from 1 January 2008. The Company has prepared contemporaneous documentation in accordance with applicable PRC tax laws and regulations and is currently awaiting confirmation from its in-charge tax authority.
 
We are subject to tax in numerous jurisdictions around the world. There are audits in progress and items under review. Difference in positions taken by taxation authorities over the interpretation and application of tax laws and regulations may increase our tax liability. Management has assessed the possible future outcome of matters that are currently under dispute. The Company believes that an adequate provision for future tax liability has been included in interim condensed consolidated financial statements based on available information.
 
In addition to the matters mentioned above, we are dealing with a number of other lawsuits and arbitrations that arise in the ordinary course of business.

ITEM 9. THE OFFER AND LISTING
 
Not applicable, except for Item 9.A.4 and Item 9.C.
 
We listed our shares on the Hong Kong Stock Exchange and our ADSs on the New York Stock Exchange in February 2001. Our shares are listed on the Hong Kong Stock Exchange under the stock code “00883” and our ADSs are listed on the New York Stock Exchange under the symbol “CEO.” Pursuant to certain undertakings in connection with our acquisition of Nexen, we listed our ADSs on the Toronto Stock Exchange in September 2013 under the symbol “CNU”. The listing of our ADSs on the Toronto Stock Exchange is not a new issuance of equity securities and does not generate additional funds for us. The following table sets forth, for the periods indicated, the high and low closing prices per share, as reported on the Hong Kong Stock Exchange and adjusted retroactively to reflect the stock split, and per ADS, as reported on the New York Stock Exchange and the Toronto Stock Exchange.

ITEM 10. ADDITIONAL INFORMATION
 
SHARE CAPITAL
 
Not applicable.
 
 
We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Companies Ordinance (Chapter 32 of the Laws of Hong Kong, the predecessor to the Hong Kong Companies Ordinance). Our company registration number in Hong Kong is 685974. Under the Hong Kong Companies Ordinance, we have the capacity, rights, powers and privileges of a natural person of
 
 
98

 
 
full age and may do anything which we are permitted or required to do by our articles of association or any enactment or rule of law.
 
The following are summaries of provisions of our articles of association and the Hong Kong Companies Ordinance. By operation of this Ordinance, provisions that were previously contained in our memorandum of association are deemed to be incorporated into our articles of association except for those provisions which conflict with the Hong Kong Companies Ordinance. For further details, you should read our memorandum of association, which was filed as an exhibit to our registration statement on Form F-1 (Registration No.333-10862) and our articles of association, as amended, which was filed as an exhibit to our annual report on Form 20-F for the fiscal year of 2010. We are required by the Hong Kong Stock Exchange Listing Rules to upload, among other things, our memorandum and articles of association on our website and on the website of the Hong Kong Stock Exchange. We have complied with such requirement and as such, our memorandum and articles of association were further filed as an exhibit to the Form 6-K filed with the SEC on March 30, 2012 (File Number: 1-14966).
 
Issue of Shares
 
Under the Hong Kong Companies Ordinance our directors may, without obtaining the prior approval of our shareholders, offer to allot new shares in our company to existing shareholders on a pro rata basis. Our directors may not allot new shares of our company or grant rights to subscribe for, or to convert any security into, shares of our company in any other manner without the prior approval of our shareholders at a general meeting. Any approval given at a general meeting granting our directors power to allot shares or securities convertible into shares or to grant rights to subscribe for shares generally shall continue in force from the date of the passing of the resolution until the earlier of:

·  
the conclusion of the next annual general meeting following the passing of the resolution; and

·  
the date on which the authority given under the resolution is revoked or varied by an ordinary resolution of our shareholders in a general meeting.

If such an approval for a general mandate to issue shares is given, our Board shall have the discretion to issue such number of shares as are approved pursuant to such general mandate, and our directors may offer, allot, grant options or other rights of subscription or conversion over, or otherwise issue, such number of shares to persons at such times and for such consideration and upon such terms and conditions as our directors may determine, subject to the restrictions under the Hong Kong Stock Exchange Listing Rules.

In accordance with Hong Kong Stock Exchange Listing Rules, any such approval of the shareholders must be limited to shares not exceeding 20% of our total number of shares in issue as of the date of granting such approval plus the number of shares repurchased by us since the granting of such approval.

Dividends
 
Subject to the Hong Kong Companies Ordinance, the shareholders at a general meeting may declare dividends to be paid to shareholders. However, under our articles of association, dividends cannot be declared in excess of the amount recommended by our Board. Further, all dividends unclaimed for one year after having become payable may be invested or otherwise made use of by the directors for the benefit of our company until claimed, and all dividends unclaimed for six years after having become payable may be forfeited by the directors and shall revert to our company.

In addition to dividends declared at a general meeting, our Board may declare and pay to the shareholders interim dividends as our Board deems justified by our financial position. Our Board may also pay any fixed dividend on any shares of our company semi-annually or at other suitable intervals, whenever our financial position, in their opinion, justifies such payment.
 
 
99

 
 
Winding Up
 
If we are wound up, the surplus assets remaining after payment to all creditors are to be divided among our shareholders in proportion to the amount paid on the shares held by them respectively, and if such surplus assets are insufficient to repay the whole of the paid-up share capital, they are to be distributed so that the losses are borne by our shareholders in proportion to the amount paid up on the shares held by them respectively. The liquidator may, with the sanction of a special resolution, divide among our shareholders in specie or in kind the whole or any part of our assets or vest any part of our assets in trustees upon such trusts for the benefit of our shareholders or any of them as the resolution shall provide.

Voting Rights
 
Under the Hong Kong Companies Ordinance, any action to be taken by the shareholders at a general meeting requires the affirmative vote of either an ordinary or a special resolution passed at such meeting.

·  
An ordinary resolution is a resolution passed by a majority of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting;

·  
A special resolution is a resolution passed by not less than 75% of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting.

Generally, resolutions of shareholders are passed by ordinary resolution. However, the Hong Kong Companies Ordinance provides that certain specified matters may only approved by shareholders by way of special resolutions. These matters include, for example:

·  
alteration of the articles;

·  
change of a company’s name;

·  
reduction of share capital; and

·  
voluntary winding up.

The Hong Kong Stock Exchange Listing Rules require that voting at any general meeting must be taken by way of poll, except where the chairman, in good faith, decides to allow a resolution which relates purely a procedural or administrative matter to be voted on by a show of hands. On a poll, every shareholder who is present in person or by proxy has one vote for every share held or represented by him or her.

Any action to be taken by the shareholders requires the affirmative vote of the requisite majority of the shares at a general meeting. There are no cumulative voting rights. Accordingly, the holders of a majority of the shares voting for the election of directors can elect all the directors if they choose to do so.

Under Hong Kong law and our articles of association, shareholders who are not residents of Hong Kong may hold, vote and transfer their shares in our company in the same manner as our shareholders who are Hong Kong residents.
 
General Meetings
 
We are required to hold an annual general meeting each year within six months from the end of our financial year. We may also hold extraordinary general meetings from time to time. Our Board may convene an extraordinary general meeting at will, and shall on requisition in accordance with the Hong Kong Companies Ordinance, proceed to convene an extraordinary general meeting. Our annual general meeting and a meeting called for the purpose of passing a special resolution require at least twenty-one days’ prior notice, and any other general meeting requires at least fourteen days’ prior notice. The notice must specify the place, day and time of the meeting and, in the case of special business, the general nature of that business. The quorum for a general meeting is two shareholders present in person or by proxy. If within thirty minutes from the time appointed for the meeting a quorum is not present, the meeting, if convened upon requisition in accordance with the Hong Kong Companies Ordinance, shall be dissolved; but in any other case it shall stand adjourned to the same day in the next week at the same time and place, or to such other day, time and place as the chairman of the meeting may determine. If at such adjourned meeting a quorum is not present within thirty minutes from the time appointed for the meeting, the member or members present in person or by proxy shall be a quorum and may transact the business for which the meeting is called.
 
 
100

 
 
 
At each annual general meeting one third of our directors are to retire from office by rotation, save any director holding office as chairman or chief executive officer. The directors to retire every year are to be those who have been longest in office since their last election and the retiring directors will be eligible for re-election.
 
Modification of Rights
 
Subject to the Hong Kong Companies Ordinance, any of the rights attaching to any class of shares, unless otherwise provided for by the terms of issue of the shares of that class, may be varied or abrogated with the written consent of the holders of not less than 75% of the issued shares of that class or with the sanction of a special resolution passed at a separate general meeting of the holders of shares of that class.
 
Borrowing Powers
 
Our Board may exercise all the powers of our company to borrow money and to mortgage or charge all or any part of our undertaking, property and assets, whether present or future, and uncalled capital. Our Board may issue debentures, debenture stock, bonds or other securities of our company, whether outright or as collateral security for any debt, liability or obligation of our company or of any third party. These borrowing powers are subject to variation by a special resolution of our company.
 
Interested Transactions
 
Subject to the exceptions described below, none of our directors may vote on any contract, arrangement or proposal in which the director or any of his or her associates is materially interested. Subject to provision of the Hong Kong Companies Ordinance, our directors may vote at a board meeting or by way of written resolution of directors on the following matters:
 
·  
any contract or arrangement to give security or indemnity to the director or his or her associates for money lent or obligations incurred or undertaken by such director or his or her associates at the request of or for the benefit of our company or subsidiaries;
 
·  
any contract or arrangement for the giving by us of any security or indemnity to a third party for our debts or obligations or debts or obligations of our subsidiaries for which such director or his or her associates assumed responsibility , or guaranteed or secured in whole or in part whether alone or jointly;
 
·  
any contract or arrangement concerning offering of securities by us (or any company which we may promote or be interested in purchasing) for which the director or his or her associates is/are or is/are to be interested as a participant in the underwriting or sub-underwriting;
 
·  
any contract or arrangement in which the director or his or her associates are interested in the same manner as other holders of our securities by virtue only of their interest in our securities;
 
·  
any proposal or arrangement concerning employee benefits that do not provide privileges to our directors or their associates not generally accorded to the class of persons to whom such scheme or fund relates, including pension fund or retirement, death or disability benefits schemes; and
 
 
101

 
 
·  
any proposal or arrangement concerning the adoption, modification or operation of any employees’ share scheme involving the issue or grant of options over shares or other securities by us to, or for the benefit of, our employees or employees of our subsidiaries under which the director or his or her associates may benefit.
 
 
We have not entered into any material contracts in the last two years other than in the ordinary course of business, those described in “Item 7―Major Shareholders and Related Party Transactions  Related Party Transactions”.
 
EXCHANGE CONTROLS
 
For information on foreign exchange controls in the PRC, foreign exchange rates, hedging activities and related foreign exchange risks, see “Item 3—Key Information—Selected Financial Data,” “Item 3—Key Information—Risk Factors—Risks Relating to the PRC—Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition” and “Item 11—Qualitative and Quantitative Disclosure about Market Risk.”
 
TAXATION
 
The taxation of income and capital gains of holders of our shares or ADSs is subject to the laws and practices of the PRC, Hong Kong and the jurisdictions in which holders of our shares or ADSs are resident or otherwise subject to tax. The following is a summary of taxation provisions that are anticipated to be material based on current law and practice. This summary is subject to change and does not constitute legal or tax advice. The discussion does not deal with all possible tax consequences relating to an investment in our shares or ADSs. In particular, the discussion does not address the tax consequences under state, local or other laws, such as non-PRC, non-Hong Kong or non-U.S. laws. Accordingly, we urge you to consult your tax adviser regarding the tax consequences of owning our shares and ADSs. The discussion is based upon laws and relevant interpretations in effect as of the date of this annual report, all of which are subject to change. There is no reciprocal tax treaty in effect between Hong Kong and the United States.
 
The PRC

On April 22, 2009, the State Administration of Taxation of the PRC (the “SAT”) issued the “Notice regarding Matters on Determination of Tax Residence Status of Chinese-controlled Offshore Incorporated Enterprises under Rules of Effective Management” (the “Notice”).
 
Pursuant to the “Enterprise Income Tax Law of the PRC” (the “New EIT Law”) and the Notice, enterprises established outside of China whose “de facto management bodies” are located in China are considered Chinese Resident Enterprises, or CREs.
 
We are considered a PRC resident enterprise for purposes of the Notice. In Accordance with the Notice and the PRC income tax law as well as the formal approval from the SAT in October 2010, we are regarded as a CRE pursuant to the provisions of the New EIT Law and the Notice. Accordingly, we are required to withhold 10% corporate income tax when we make dividend distributions to the ADS depositary and to our non-Chinese resident enterprise shareholders, whose names appear on our register of members, as of the record date for such dividend, and who are not individuals. The 10% dividend withholding tax rate will not be reduced under the 1984 Agreement between the United States and the People’s Republic of China for the Avoidance of Double Taxation, or the PRC Treaty. In the past, we did not withhold any tax in respect of Dividends payable to any natural person shareholders whose names appeared on our register of members on the relevant record dates.
 
Currently, gains realized by foreign individual investors upon the sale of overseas-listed shares or American depositary shares are not subject to tax on capital gains. In accordance with the New EIT Law, capital gains realized by foreign enterprises which are non-resident enterprises in China upon the sale of overseas-listed shares or American depositary shares are generally subject to a PRC enterprise income tax levied at a rate of 10%, unless exempted or reduced pursuant to an applicable double-taxation treaty or other exemption.
 
 
 
102

 
 
 
Hong Kong
 
Tax on Dividends
 
Under the current practices of the Hong Kong Inland Revenue Department, no tax is payable in Hong Kong on dividends paid by us.
 
Profits Tax
 
No tax is imposed in Hong Kong in respect of capital gains from the sale of property, such as the shares and ADSs. Trading gains from the sale of property by persons carrying on a trade, profession or business in Hong Kong where such gains are derived from or arise in Hong Kong from such trade, profession or business will be subject to Hong Kong profits tax which is currently imposed at a rate of 16.5% on corporations and at a standard rate of 15% on individuals. Gains from sales of shares effected on the Hong Kong Stock Exchange will be considered to be derived from or arise in Hong Kong. Liability for Hong Kong profits tax will therefore arise in respect of trading gains from sales of shares realized by persons carrying on a business of trading or dealing in securities in Hong Kong.
 
Stamp Duty
 
Hong Kong stamp duty, currently charged at the rate of HK$1.00 per HK$1,000 or part thereof on the higher of the consideration for, or the value of, the shares, will be payable by the purchaser on every purchase and by the seller on every sale of shares. A total of HK$2.00 per HK$1,000 or part thereof is currently payable on a typical sale and purchase transaction involving shares. In addition, a fixed duty of HK$5.00 is currently payable on any instrument of transfer of shares. The withdrawal of shares upon the surrender of ADSs, and the issuance of ADSs upon the deposit of shares, will also attract stamp duty at the rate described above for sale and purchase transactions unless the withdrawal or deposit does not result in a change in the beneficial ownership of the shares under Hong Kong law. The issuance of the ADSs upon the deposit of shares issued directly to the depositary or for the account of the depositary does not incur stamp duty if it does not involve a change of beneficial ownership in the shares. No Hong Kong stamp duty is payable upon the transfer of ADSs outside Hong Kong.
 
U.S. Federal Income Tax Considerations
 
The following is a discussion of material U.S. federal income tax consequences of owning and disposing of ADSs or shares by the U.S. Holders described below, but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to a particular person’s decision to own such ADSs or shares. This discussion does not address the potential application of the Medicare contribution tax to “net investment income” of non-corporate U.S. Holders. In addition, this discussion does not address U.S. state, local and non-U.S. tax consequences. The discussion applies only to U.S. Holders who hold ADSs or shares as capital assets for U.S. federal income tax purposes and does not address all of the U.S. federal income tax consequences that may be relevant to U.S. Holders that are subject to special rules, such as:

·  
certain financial institutions;
·  
dealers or traders in securities who use a mark-to-market method of tax accounting;
·  
persons holding ADSs or shares as part of a straddle, conversion transaction, integrated transaction or similar transaction;
·  
persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;
·  
partnerships or other entities classified as partnerships for U.S. federal income tax purposes;
·  
persons liable for the alternative minimum tax;
·  
tax-exempt entities, including “individual retirement accounts” or “Roth IRAs”;
·  
persons that own or are deemed to own 10% or more of our voting stock;
 
 
103

 
 
·  
persons who acquired our ADSs or shares pursuant to the exercise of an employee stock option or otherwise as compensation; or
·  
persons holding shares in connection with a trade or business conducted outside of the United States.

If an entity that is classified as a partnership for U.S. federal income tax purposes owns ADSs or shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships owning ADSs or shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the ADSs or shares.
 
This discussion is based on the Internal Revenue Code of 1986, as amended (the Code), administrative pronouncements, judicial decisions, final, temporary and proposed U.S. Treasury regulations and the PRC Treaty, all as of the date hereof. These laws are subject to change, possibly on a retroactive basis. It is also based, in part, on representations by the Depositary and assumes that each obligation under the Deposit Agreement and any related agreement will be performed in accordance with its terms. U.S. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of ADSs or shares in their particular circumstances.
 
As used herein, a “U.S. Holder” is a person that for U.S. federal income tax purposes is a beneficial owner of ADSs or shares and is: (i) a citizen or individual resident of the United States; (ii) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; or (iii) an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.
 
In general, a U.S. Holder who owns ADSs should be treated as the owner of the underlying shares represented by those ADSs for U.S. federal income tax purposes. Accordingly, no gain or loss should be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those ADSs.
 
The U.S. Treasury has expressed concerns that parties to whom American depositary shares are released before delivery of shares to the depositary (a pre-release), or intermediaries in the chain of ownership between holders and the issuer of the securities underlying the American depository shares, may be taking actions that are inconsistent with the claiming of foreign tax credits by holders of American depositary shares. Such actions would also be inconsistent with the claiming of the favorable tax rates, described below, applicable to dividends received by certain non-corporate holders. Accordingly, the creditability of foreign taxes and the availability of the favorable tax rates for dividends received by certain non-corporate holders, described below, could be affected by actions taken by such parties or intermediaries.
 
This discussion assumes that we were not a passive foreign investment company, or PFIC, for the taxable year ended December 31, 2014, as described below, and that we will not become a PFIC.
 
Taxation of Distributions
 
Distributions received by a U.S. Holder on ADSs or shares, other than certain pro rata distributions of common shares to all shareholders, will constitute foreign-source dividend income to the extent paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends. Dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s or, in the case of ADSs, the Depositary’s receipt of the dividend. The amount of the dividend will equal the U.S. dollar value of the Hong Kong dollar distribution, calculated by reference to the exchange rate in effect on the date of receipt, regardless of whether the payment is converted into U.S. dollars on the date of receipt. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder should not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt. Corporate U.S. Holders will not be entitled to claim a dividends-received deduction with respect to dividends paid by us.
 
 
104

 
 
 
Subject to applicable limitations and the discussion above regarding concerns expressed by the U.S. Treasury, dividends paid by “qualified foreign corporations” to certain non-corporate U.S. shareholders are taxable at rates applicable to long-term capital gains. A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid on stock that is readily tradable on an established securities market in the United States, such as the New York Stock Exchange where our ADSs are traded. A foreign corporation may also be treated as a qualified foreign corporation if it is eligible for benefits of a comprehensive income tax treaty with the United States determined by the U.S. Treasury to be satisfactory for these purposes and that includes an exchange of information program. Non-corporate U.S. Holders should consult their tax advisers to determine whether these favorable rates may apply to dividends they receive from us and whether they are subject to any special rules that limit their ability to be taxed at these favorable rates.
 
As described in “—Taxation—The PRC,” we are regarded as a CRE pursuant to the provisions of the New EIT Law and the Notice. Accordingly, dividends paid with respect to our ordinary shares or ADSs may be subject to PRC withholding taxes. For U.S. federal income tax purposes, the amount of a dividend would include any amounts withheld by us in respect of PRC taxes. Subject to applicable limitations, any PRC income taxes withheld from dividends on ADSs or shares (in the case of a U.S. Holder that is eligible for the benefits of the PRC Treaty, at a rate not exceeding the rate provided by the PRC Treaty) may be creditable against the U.S. Holder’s U.S. federal income tax liability. Where a U.S. Holder is eligible for the benefits of the PRC Treaty, PRC taxes withheld in excess of the rate applicable under the PRC Treaty will not be eligible for credit against the U.S. Holder’s U.S. federal income tax liability. The rules governing foreign tax credits are complex, and U.S. Holders should consult their tax advisers regarding the creditability of foreign taxes in their particular circumstances. Instead of claiming a credit, a U.S. Holder may, at the U.S. Holder’s election, deduct such PRC taxes in computing taxable income, subject to applicable limitations. An election to deduct foreign taxes instead of claiming foreign tax credits must apply to all foreign taxes paid or accrued in the taxable year.

Sale or Other Disposition of ADSs or Shares
 
A U.S. Holder will generally recognize capital gain or loss on the sale or other disposition of ADSs or shares, which will be long-term capital gain or loss if the U.S. Holder has held such ADSs or shares for more than one year. The amount of the U.S. Holder’s gain or loss will be equal to the difference between the amount realized on the sale or other disposition and the U.S. Holder’s tax basis in the ADSs or shares (each determined in U.S. dollars). Any gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes.
 
As described in “—Taxation —The PRC,” gains from dispositions of our ADSs or shares may be subject to PRC tax. A U.S. Holder’s amount realized would include the gross amount of the disposition proceeds before any withholding or deduction of PRC tax. Although under the Code any such gain of a U.S. Holder would generally be characterized as U.S.-source income, a U.S. Holder that is eligible for the benefits of the PRC Treaty may be able to elect to treat the gain as foreign-source gain for foreign tax credit purposes. The rules governing foreign tax credits are complex and the creditability of foreign taxes is subject to limitations. U.S. Holders should consult their tax advisers regarding their eligibility for benefits under the PRC Treaty and the creditability of any PRC tax paid with respect to dispositions in their particular circumstances.
 
Passive Foreign Investment Company Considerations
 
We believe that we were not a PFIC for U.S. federal income tax purposes for our taxable year ended December 31, 2014. In general, a non-U.S. company will be considered a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. As PFIC status depends upon the composition of our income and assets and the market value of our assets from time to time, and since there are uncertainties in the manner of application of the PFIC rules, there can be no assurance that we will not be considered a PFIC for any taxable year.

If we were to be treated as a PFIC for any taxable year during which a U.S. Holder held ADSs or shares, certain adverse U.S. federal income tax rules would apply on a disposition (including certain pledges) of ADSs or shares by the U.S. Holder. In general, under those rules, gain recognized by the U.S. Holder on a sale or other disposition of ADSs or shares would be allocated ratably over the U.S. Holder’s holding period for the ADSs or shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for such taxable year, and an interest charge would be imposed on the resulting tax liability for each such taxable year. Any distribution in respect of ADSs or shares in excess of 125% of the average of the annual distributions on ADSs or shares received by the U.S. Holder during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, would be subject to taxation in the same manner. Certain elections (such as a mark-to-market election) may be available to U.S. Holders and may result in alternative tax treatment.
 
In addition, if we were to be treated as a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the favorable rates discussed above with respect to dividends received by certain non-corporate U.S. Holders would not apply.
 
If we are a PFIC for any taxable year during which a U.S. Holder owned our ADSs or shares, the U.S. Holder will generally be required to file annual reports on IRS Form 8621.

Information Reporting and Backup Withholding
 
Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries may be subject to information reporting and backup withholding, unless the U.S. Holder is an exempt recipient or, in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle such U.S. Holder to a refund, provided that the required information is timely furnished to the Internal Revenue Service.

ITEM 11. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK
 
Our market risk exposures primarily consist of fluctuations in oil and gas prices, exchange rates and interest rates.
 
Commodity Price Risks

We are exposed to fluctuations in prices of crude oil. International oil prices are volatile and this volatility has a significant effect on our net sales and profit. We do not hedge market risk resulting from fluctuations in oil prices. See “Item 4—Information on the Company—Business Overview—Overview” and “Item 3—Key Information—Risk Factors—Risks Relating to Our Operations—Our business, revenues and profits fluctuate with changes in oil and gas prices.”
 
Currency Risk

Our foreign exchange exposure gives rise to market risk associated with exchange rate movements.
 
Substantially all of our oil and gas sales are denominated in Renminbi and U.S. dollars. On July 21, 2005, China reformed its exchange rate regime by adopting a managed floating exchange rate approach based on market supply and demand and with reference to a basket of currencies. Renminbi was no longer pegged to U.S. dollars. From January 1, 2014 to March 31, 2015, Renminbi depreciated approximately 0.7% against U.S. dollar.
 
Our management has assessed our exposure to foreign currency risk by using a sensitivity analysis on the change in foreign exchange rate of the US dollars, to which we are mainly exposed to as at December 31, 2014. Based on our management's assessment, a 5% change in the foreign exchange rate of the US dollars at December 31, 2014 would have impacted our profit for the year by 0.06%. This analysis has been determined assuming that the change in foreign exchange rates had occurred at the end of the reporting period and had been applied to the foreign currency balances to which we have significant exposure with all other variables held constant.
 
The depreciation of Renminbi against U.S. dollar may have the following impact on us:
 
·  
Our oil and gas sales may increase, because the benchmark oil and gas prices are usually in U.S. dollars;
 
·  
Our cost for imported equipment and materials will increase, because most of these costs are denominated in U.S. dollars; and
 
·  
Our debt repayment burden will increase, since all of our debt is denominated in U.S. dollars.
 
For further information on our currency risk, see “Item 3—Key Information—Risk Factors—Risks Relating to the PRC—Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition.”
 
Interest Rate Risk

We are exposed to interest rate risk arising from our debts. An upward fluctuation in interest rates increases the cost of new debt and the cost of servicing our floating rate debt. We may use interest rate swap transactions, from time to time, to hedge our interest rate exposure when considered appropriate, based on existing and anticipated market conditions.
 
As of December 31, 2014, the interest rates for 79.2% of our outstanding debts were fixed. The term of the weighted average balance was approximately 9.5 years. A fixed interest rate can reduce the volatility of finance costs in uncertain markets. We do not currently engage in any interest rate hedging activities.

As of December 31, 2014, the interest rates for 99.0% of our total outstanding long-term debts were fixed. The following table sets forth additional information about the expected maturity dates of our outstanding long-term debt (including the current portion) as of December 31, 2014.

An evaluation was carried out under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness, as of December 31, 2014, of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act).
 
Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2014, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported as and when required by the SEC’s rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
(b)           Management’s annual report on internal control over financial reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2014 using the criteria set forth in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management has concluded that our internal control over financial reporting as of December 31, 2014 was effective.

ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT
 
On March 22, 2013, our Board resolved, as recommended by our audit committee, to propose change in our independent registered public accounting firm, Ernst & Young, after the completion of the audit of the consolidated financial statements for the year ended December 31, 2012, with effect from the conclusion of our 2012 annual general meeting held on May 24, 2013, due to the requirements of the Ministry of Finance of the PRC and the State-owned Assets Supervision and Administration Commission of the State Council of the PRC in respect of the term of office of the auditors. As a result, Ernst & Young did not offer themselves for re-appointment at our 2012 annual general meeting on May 24, 2013.

The report of Ernst & Young on our consolidated financial statements for the fiscal year ended December 31, 2012 did not contain any adverse opinion or a disclaimer of opinion, nor was such report qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal year ended December 31, 2012 and through May 24, 2013, there were no disagreements with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Ernst & Young, would have caused it to make reference to the subject matter of the disagreements in their report on the consolidated financial statements for such years.

During the fiscal year ended December 31, 2012 and through May 24, 2013, there were no “reportable events” (hereinafter defined) requiring disclosure pursuant to Item 16F(a)(1)(v) of Form 20-F. As used herein, the term “reportable event” means any of the items listed in paragraphs (a)(1)(v)(A)-(D) of Item 16F of Form 20-F.
 
 
112

 
 
 
We provided a copy of this disclosure to Ernst & Young and requested that Ernst & Young furnish a letter addressed to the SEC stating whether it agrees with the above statements, and if not, stating the respects in which they do not agree. A copy of the letter from Ernst & Young addressed to the SEC, dated April 17, 2014, was filed as Exhibit 15.7 to the Form 20-F for the year ended December 31, 2013 which we filed with the SEC on April 17, 2014.
 
On March 22, 2013, our Board resolved, as recommended by our audit committee, to propose to appoint Deloitte Touche Tohmatsu, or Deloitte, as our independent registered public accounting firm, which was approved by our shareholders at our 2012 annual general meeting held on May 24, 2013. As a result, Deloitte Touche Tohmatsu was appointed as our independent registered public accounting firm as of May 24, 2013. During the two most recent fiscal years and through May 24, 2013, neither we nor anyone on our behalf consulted Deloitte regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us that Deloitte concluded was an important factor considered by us in reaching a decision as to the accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a “disagreement”, as defined in Item 16F(a)(1)(iv) of Form 20-F and related instructions to Item 16-F of Form 20-F, with Deloitte or a “reportable event” as described in Item 16F(a)(1)(v) of Form 20-F.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CNOOC Limited

We have audited the accompanying consolidated statements of financial position of CNOOC Limited (the "Company") and its subsidiaries (collectively referred to as the "Group") as of December 31, 2014 and 2013, and the related consolidated statements of profit or loss and other comprehensive income, consolidated statements of changes in equity, and consolidated statements of cash flows for each of the two years in the period ended December 31, 2014. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Group as of December 31, 2014 and 2013, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2014 in conformity with International Financial Reporting Standards issued by the International Accounting Standards Board, and Hong Kong Financial Reporting Standards issued by the Hong Kong Institute of Certified Public Accountants.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Group's internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 27, 2015 expressed an unqualified opinion on the Group's internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Shareholders of CNOOC Limited

We have audited the internal control over financial reporting of CNOOC Limited (the "Company") and its subsidiaries (collectively referred to as the "Group") as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying "Management’s annual report on internal control over financial reporting". Our responsibility is to express an opinion on the Group's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2014 of the Group and our report dated March 27, 2015 expressed an unqualified opinion on those financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Shareholders of CNOOC Limited
(Incorporated in Hong Kong with limited liability)

We have audited the accompanying consolidated statement of profit or loss and other comprehensive income, statement of changes in equity and statement of cash flows of CNOOC Limited and its subsidiaries (the “Group”)  for the year ended December 31, 2012.

Management’s responsibility for the consolidated financial statements
Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial Reporting Standards issued by the International Accounting Standards Board, and Hong Kong Financial Reporting Standards issued by the Hong Kong Institute of Certified Public Accountants, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ responsibility
Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and Hong Kong Standards on Auditing issued by the Hong Kong Institute of Certified Public Accountants. Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entity's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion
In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated results of operations and cash flows of the Group for the year ended December 31, 2012, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and Hong Kong Financial Reporting Standards as issued by the Hong Kong Institute of Certified Public Accountants.

CHANGES IN ACCOUNTING POLICY AND DISCLOSURES

The IASB has issued a number of new and revised IFRSs that are first effective for the current accounting year commencing January 1, 2014 or later but available for early adoption. The equivalent new and revised HKFRSs consequently issued by the HKICPA have the same effective dates as those issued by the IASB and are in all material aspects identical to the pronouncements issued by the IASB.

The accounting policies adopted are consistent with those of the year ended December 31, 2013, except for the first time adoption of the amendments to IFRSs/HKFRSs and the new interpretation effective for the Group’s financial year beginning on January 1, 2014. The adoption of those amendments and the interpretation upon their effective dates has had no material impact on the accounting policies, the disclosures or the amounts recognised in the consolidated financial statements of the Group.

The Group has not applied the following new and revised IFRSs/HKFRSs, which may be relevant to the Group and have been issued but are not yet effective, in these consolidated financial statements:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of preparation

These consolidated financial statements have been prepared under the historical cost convention, except for as detailed in the accounting policies notes hereafter. These consolidated financial statements are presented in Renminbi ("RMB") and all values are rounded to the nearest million except when otherwise indicated.

Basis of consolidation

The consolidated financial statements include the financial statements of the Company and its subsidiaries for the year ended December 31, 2014.

The results of subsidiaries are consolidated from the date of acquisition, being the date on which the Group obtains control, and continue to be consolidated until the date that such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies.

The results of subsidiaries are included in the Company's statement of profit or loss and other comprehensive income to the extent of dividends received and receivable. The Company's interests in subsidiaries are stated at cost less any impairment losses.

All intra-group balances, income and expenses and unrealised gains and losses and dividends resulting from intra-group transactions are eliminated in full.

Business combinations and goodwill

Business combinations are accounted for using the acquisition method. The consideration transferred is measured at acquisition date fair value which is the sum of the acquisition date fair values of assets transferred by the Group, liabilities assumed by the Group to the former owners of the acquiree and the equity interests issued by the Group in exchange for control of the acquiree.  For each business combination, the Group elects whether it measures the non-controlling interests in the acquiree either at fair value or at the proportionate share of the acquiree's identifiable net assets. All other components of non-controlling interests are measured at fair value. Acquisition related costs incurred are expensed and included in administrative expenses.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree.

If the business combination is achieved in stages, the acquirer's previously held equity interest in the acquiree is remeasured to fair value at the acquisition date through profit or loss.

Any contingent consideration to be transferred by the acquirer is recognised at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IAS 39/HKAS 39 is measured at fair value with subsequent changes in fair value recognised in profit or loss. If the contingent consideration is not within the scope of IAS 39/HKAS 39, it is measured in accordance with the appropriate IFRS/HKFRS.  Contingent consideration that is classified as equity is not remeasured and subsequent settlement is accounted for within equity.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred, the amount recognised for non-controlling interests and any fair value of the Group's previously held equity interests in the acquiree over the identifiable net assets acquired and liabilities assumed. If the sum of this consideration and other items is lower than the fair value of the net assets of the subsidiary acquired, the difference is recognised in profit or loss as a gain on bargain purchase.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Business combinations and goodwill (continued)

After initial recognition, goodwill is measured at cost less any accumulated impairment losses.  Goodwill is tested for impairment annually or more frequently if events or changes in circumstances indicate that the carrying value may be impaired. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group's cash-generating units, or groups of cash-generating units, that are expected to benefit from the synergies of the combination, irrespective of whether other assets or liabilities of the Group are assigned to those units or groups of units.

Impairment is determined by assessing the recoverable amount of the cash-generating unit (group of cash-generating units) to which the goodwill relates. Where the recoverable amount of the cash-generating unit (group of cash-generating units) is less than the carrying amount, an impairment loss on goodwill is recognised. An impairment loss recognised for goodwill is not reversed in a subsequent period.

Where goodwill has been allocated to a cash-generating unit (or group of cash-generating units) and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on the disposal. Goodwill disposed of in these circumstances is measured based on the relative value of the operation disposed of and the portion of the cash-generating unit retained.

Subsidiaries

Subsidiaries are all those entities over which the Group has power over the investee such that the Group is able to direct the relevant activities, has exposure or rights to variable returns from its involvement with the investee and has the ability to use its power over the investee to affect the amount of the investor's returns.

Associates

Based on the Group's ownership percentage (considering its direct ownership as well as potentially exercisable or convertible shares) and other contractual rights, the Group has significant influence over its associates, rather than the power to control.

The Group's investments in associates are stated in the consolidated statement of financial position at the Group's share of net assets under the equity method of accounting, less any impairment losses. Adjustments are made to bring into line any dissimilar accounting policies that may exist.  The Group's share of the post-acquisition results and reserves of associates is included in the consolidated statement of profit or loss and other comprehensive income and consolidated reserves, respectively. Unrealised gains and losses resulting from transactions between the Group and its associates are eliminated to the extent of the Group's investments in the associates, except where unrealised losses provide evidence of an impairment of the asset transferred. Goodwill arising from the acquisition of associates is included as part of the Group's investments in associates and is not individually tested for impairment.

The results of associates are included in the Company's statement of profit or loss and other comprehensive income to the extent of dividends received and receivable. The Company's investments in associates are treated as non-current assets and are stated at cost less any impairment losses. Non-current asset (or disposal group) classified as held for sale are measured at the lower of its carrying amount and fair value less costs to sell.

Joint arrangements

Certain of the Group's activities are conducted through joint arrangements. Joint arrangements are classified as either a joint operation or joint venture, based on the rights and obligations arising from the contractual obligations between the parties to the arrangement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Joint arrangements (continued)

Joint control

Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control.

Joint operations

Some arrangements have been assessed by the Group as joint operations as both parties to the contract are responsible for the assets and obligations in proportion to their respective interest, whether or not the arrangement is structured through a separate vehicle. This evaluation applies to both the Group's interests in production sharing arrangements and certain joint operation.

The Group entered into numerous production sharing arrangements or similar agreements in China and overseas countries. The Group's participating interest may vary in each arrangement. The Group, as one of the title owners under certain exploration and/or production licenses or permits, is required to bear exploration (with some exceptions in China), development and operating costs together with other co-owners based on each owner's participating interest. Once production occurs, a certain percentage of the annual production or revenue is first distributed to the local government, which, in most cases, with the nature of royalty and other taxes or expenses, and the rest of the annual production or revenue is allocated among the co-owners.

The Group accounts for the assets, liabilities, revenues and expenses relating to its interest in a joint operation in accordance with the IFRSs/HKFRSs applicable to the particular assets, liabilities, revenues and expenses.

Joint venture

A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement.

The Group's investments in joint ventures are stated in the consolidated statement of financial position at the Group's share of net assets under the equity method of accounting, less any impairment losses. Adjustments are made to bring into line any dissimilar accounting policies that may exist. The Group's share of the post-acquisition results and reserves of joint ventures is included in the consolidated statement of profit or loss and other comprehensive income and consolidated reserves, respectively. Where the profit sharing ratios is different to the Group's equity interest, the share of post-acquisition results of the joint ventures is determined based on the agreed profit sharing ratio. Unrealised gains and losses resulting from transactions between the Group and its joint ventures are eliminated to the extent of the Groups investments in the joint ventures, except where unrealised losses provide evidence of an impairment of the asset transferred. Goodwill arising from the acquisition of joint ventures is included as part of the Group's investments in joint ventures and is not individually tested for impairment.

The results of joint ventures are included in the Company's statement of profit or loss and other comprehensive income to the extent of dividend received and receivable. The Company's investments in joint ventures are treated as non-current assets and are stated at cost less any impairment losses. Non-current asset (or disposal group) classified as held for sale is measured at the lower of its carrying amount and fair value less costs to sell.

the entity is controlled or jointly controlled by a person identified in (a); and
 
(vii)  
a person identified in (a)(i) has significant influence over the entity or is a member of the key management personnel of the entity (or of a parent of the entity).

Impairment of non-financial assets other than goodwill

Where an indication of impairment exists, or when annual impairment testing for an asset is required (other than inventories, deferred tax assets, financial assets and goodwill), the asset's recoverable amount is estimated. An asset's recoverable amount is the higher of the asset's or cash-generating unit's value in use and its fair value less costs of disposal, and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets, in which case the recoverable amount is determined for the cash-generating unit to which the asset belongs.

An impairment loss is recognised only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to profit or loss in the period in which it arises in those expense categories consistent with the function of the impaired asset.

An assessment is made at the end of each reporting period as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such an indication exists, the recoverable amount is estimated. A previously recognised impairment loss of an asset other than goodwill is reversed only if there has been a change in the estimates used to determine the recoverable amount of that asset, but not to an amount higher than the carrying amount that would have been determined (net of any depreciation/amortisation) had no impairment loss been recognised for the asset in prior years. A reversal of such an impairment loss is credited to profit or loss in the period in which it arises.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Property, plant and equipment

Property, plant and equipment comprise oil and gas properties, and vehicles and office equipment and others.

(a)  
Oil and gas properties

For oil and gas properties, the successful efforts method of accounting is adopted. The Group capitalises the initial acquisition costs of oil and gas properties. Impairment of initial acquisition costs is recognised based on exploratory experience and management judgement and charged to profit and loss as exploration expenses. Upon discovery of commercial reserves, acquisition costs are transferred to proved properties. The costs of drilling and equipping successful exploratory wells, all development expenditures on construction, installation or completion of infrastructure facilities such as platforms, pipelines, processing plants and the drilling of development wells and the building of enhanced recovery facilities, including those renewals and betterments that extend the economic lives of the assets, and the related borrowing costs are capitalised. The costs of unsuccessful exploratory wells and all other exploration costs are expensed as incurred.

The Group carries exploratory well costs as an asset when the well has found a sufficient quantity of reserves to justify its completion as a producing well and where the Group is making sufficient progress assessing the reserves and the economic and operating viability of the project. Exploratory well costs not meeting these criteria are charged to expenses. Exploratory wells that discover potentially economic reserves in areas where major capital expenditure will be required before production would begin and when the major capital expenditure depends upon the successful completion of further exploratory work remain capitalised and are reviewed periodically for impairment.

Producing oil and gas properties are depreciated on a unit-of-production basis over the proved developed reserves. Common facilities that are built specifically to service production directly attributed to designated oil and gas properties are depreciated based on the proved developed reserves of the respective oil and gas properties on a pro-rata basis. Common facilities that are not built specifically to service identified oil and gas properties are depreciated using the straight-line method over their estimated useful lives. Costs associated with significant development projects are not depreciated until commercial production commences and the reserves related to those costs are excluded from the calculation of depreciation.

Capitalised acquisition costs of proved properties are depreciated on a unit-of-production method over the total proved reserves of the relevant oil and gas properties.

(b)  
Vehicles, office equipment and others

Vehicles, office equipment and others are stated at cost less accumulated depreciation and impairment losses. The straight-line method is adopted to depreciate the cost less any estimated residual value of these assets over their expected useful lives. The useful lives of vehicles, office equipment and other assets are in line with their beneficial periods.

Where parts of an item of property, plant and equipment have different useful lives, the cost of that item is allocated on a recoverable basis among the parts and each part is depreciated separately.

Residual values, useful lives and the depreciation method are reviewed and, adjusted if appropriate, at each reporting date.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Property, plant and equipment (continued)

Any gains and losses on disposals of property, plant and equipment (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) are recognised in profit or loss.

Intangible assets (other than goodwill)

The intangible assets of the Group comprise software, gas processing rights of the NWS Project, marketing transportation and storage contracts, drilling rig contracts and seismic data usage rights. Intangible assets with finite lives are carried at cost, less accumulated amortisation and accumulated impairment losses. The cost of intangible assets acquired in a business combination is the fair value as at the date of acquisition. Intangible assets with finite lives except for gas processing rights, are amortised on the straight-line basis over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortisation period and the amortisation method for an intangible asset with a finite useful life are reviewed at least at each financial year end.

The intangible assets regarding software have been amortised on the straight-line basis over their respective useful lives. The intangible asset regarding the gas processing rights has been amortised upon the commercial production of the liquefied natural gas on a unit-of-production basis over the total proved reserves of the relevant asset. The intangible assets regarding the marketing transportation and storage contracts and drilling rig contracts are amortised over the life of the contracts on the straight-line basis. The intangible assets related to the seismic data usage rights are amortised over the estimated useful life of the seismic data.

Major maintenance and repairs

Expenditure on major maintenance refits or repairs comprises the cost of replacement assets or parts of assets and overhaul costs. Where an asset or part of an asset that was separately depreciated and is replaced, and it is probable that future economic benefits associated with the item will flow to the Group, the replacement expenditure is capitalised. Where part of the asset was not separately considered as a component, the replacement value is used to estimate the carrying amount of the replaced assets which is immediately written off. All other maintenance costs are expensed as incurred.

Research and development costs

All research costs are expensed as incurred.

Expenditure (other than that relating to oil and gas properties discussed above) incurred on projects to develop new products is capitalised and deferred only when the Group can demonstrate the technical feasibility of completing the intangible asset so that it will be available for use or sale, its intention to complete and its ability to use or sell the asset, how the asset will generate future economic benefits, the availability of resources to complete the project and the ability to measure reliably the expenditure during the development. Product development expenditure which does not meet these criteria is expensed when incurred.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Financial assets

Initial recognition and measurement

Financial assets within the scope of IAS 39/HKAS 39 are classified as financial assets at fair value through profit or loss, loans and receivables, held-to-maturity investments, and available-for-sale financial assets, as appropriate. The Group determines the classification of its financial assets at initial recognition. When financial assets are recognised initially, they are measured at fair value plus transaction costs, except in the case of financial assets recorded at fair value through profit or loss.

Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way purchases or sales) are recognised on the trade date, that is, the date that the Group commits to purchase or sell the asset.

The Group's financial assets include cash and bank balances, trade and other receivables, equity and debt investments, and derivative financial instruments.

Subsequent measurement

The subsequent measurement of financial assets depends on their classifications as follows:

 
(a)  
Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets designated upon initial recognition at fair value through profit or loss and financial assets classified as held-for-trading. Financial assets at fair value through profit and loss are carried in the statement of financial position at fair value with net changes in fair value recognised in profit or loss in the period. These net fair value changes do not include any dividends or interest earned on these financial assets, which are recognised in accordance with the policies set out for "Revenue recognition" below.

 
(b)  
Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. After initial measurement, such assets are subsequently carried at amortised cost using the effective interest method less any allowance for impairment. Amortised cost is calculated by taking into account any discount or premium on acquisition and includes fees or costs that are an integral part of the effective interest rate. Gains and losses are recognised in profit or loss when the loans and receivables are derecognised or impaired, as well as through the amortisation process.

 
(c)  
Held-to-maturity investments

Non-derivative financial assets with fixed or determinable payments and fixed maturity are classified as held to maturity when the Group has the positive intention and ability to hold them to maturity. Held-to-maturity investments are subsequently measured at amortised cost using the effective interest rate method less any allowance for impairment. Amortised cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. Gains and losses are recognised in profit or loss when the investments are derecognised or impaired, as well as through the amortisation process.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Financial assets (continued)

Subsequent measurement (continued)

 
(d)  
Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial assets in listed and unlisted equity investments and debt securities. Equity investments classified as available for sale are those which are neither classified as held for trading nor designated at fair value through profit or loss. Debt securities in this category are those which are intended to be held for a long period of time and which may be sold in response to needs for liquidity or in response to changes in market conditions.

After initial recognition, available-for-sale financial assets are measured at fair value, with unrealised gains or losses recognised as other comprehensive income in the available-for-sale investment revaluation reserve until the investment is derecognised, at which time the cumulative gain or loss is recognised in profit or loss, or until the investment is determined to be impaired, at which time the cumulative loss is reclassified from the available-for-sale investment revaluation reserve to profit or loss. Interest and dividends earned whilst holding the available-for-sale financial investments are reported as interest income and dividend income, respectively and are recognised in profit or loss in accordance with the policies set out for "Revenue recognition" below.

When the fair value of unlisted equity investments cannot be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant for that investment or (b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such investments are stated at cost less any impairment losses.

Fair value

The fair value of financial instruments that are traded in active markets at each reporting date is determined by reference to quoted market prices or dealer price quotations, without any deduction for transaction costs.

For financial instruments not traded in an active market, the fair value is determined using appropriate valuation techniques. Such techniques may include using recent arm's length market transactions; reference to the current fair value of another instrument that is substantially the same; a discounted cash flow analysis or other valuation models.

An analysis of fair values of financial instruments and further details as to how they are measured are provided in note 34.

Impairment of financial assets

The Group assesses at each reporting date whether there is any objective evidence that a financial asset or a group of financial assets may be impaired.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Impairment of financial assets (continued)

 
(a)  
Assets carried at amortised cost

If there is objective evidence that an impairment loss on loans and receivables or held-to-maturity investments carried at amortised cost has been incurred, the amount of the loss is measured as the difference between the asset's carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset's original effective interest rate (the effective interest rate computed at initial recognition). The carrying amount of the asset is reduced either directly or through the use of an allowance account. The amount of the impairment loss is recognised in profit or loss.

If, in a subsequent year, the amount of the estimated impairment loss increases or decreases and the decrease can be related objectively to an event occurring after the impairment was recognised, the previously recognised impairment loss is increased or reduced either directly or by adjusting the allowance account. Any subsequent reversal of an impairment loss is recognised in profit or loss, to the extent that the carrying value of the asset does not exceed amortised cost at the reversal date.

In relation to trade and other receivables, a provision for impairment is made when there is objective evidence (such as the probability of insolvency or significant financial difficulties of the debtor and significant changes in the technological, market, economic or legal environment that have an adverse effect on the debtor) that the Group will not be able to collect all of the amounts due under the original terms of an invoice.

 
(b)  
Assets carried at cost

If there is objective evidence that an impairment loss has incurred on an unquoted equity instrument that is not carried at fair value because its fair value cannot be reliably measured, the amount of the loss is measured as the difference between the asset's carrying amount and the present value of estimated future cash flows discounted at the current market rate of return for a similar financial asset. Impairment losses on these assets are not reversed.

 
(c)  
Available-for-sale financial assets

If an available-for-sale asset is impaired, an amount comprising the difference between its cost (net of any principal payment and amortisation) and its current fair value, less any impairment loss previously recognised in profit or loss, is removed from other comprehensive income and recognised in profit or loss.

Equity investments are impaired if there is a significant or prolonged decline in fair value of the investment below its cost or where other objective evidence of impairment exists. Impairment of debt instruments is assessed based on the same criteria as assets carried at amortised cost. Impairment losses on equity instruments are not reversed through profit or loss; increases in their fair value after impairments are recognised directly in equity. Impairment losses on debt instruments are reversed through profit or loss, if the increase in fair value of the instruments can be objectively related to an event occurring after the impairment loss was recognised in profit or loss.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Derecognition of financial assets

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is derecognised when:

 
(i)  
The contractual rights to receive cash flows from the asset have expired; or
 
(ii)  
the Group has transferred its rights to receive cash flows from the asset, or the Group retains the contractual rights to receive the cash flows from the asset, but has assumed an obligation to pay the received cash flows in full without material delay to a third party under a "pass-through" arrangement; and either (a) has transferred substantially all the risks and rewards of the asset, or (b) has neither transferred nor retained substantially all the risks and rewards of the asset, but has no control of the asset.

When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent it has retained the risk and rewards of ownership of the asset. When it has neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the Group continues to recognise the transferred asset to the extent of the Group's continuing involvement. In that case, the Group also recognises an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.

Financial liabilities at amortised cost (including interest-bearing loans and borrowings)

Financial liabilities including trade and other payables and interest-bearing loans and borrowings are initially stated at fair value less directly attributable transaction costs and are subsequently measured at amortised cost, using the effective interest method. The related interest expense is recognised within "Finance costs" in profit or loss.

Gains and losses are recognised in profit or loss when the liabilities are derecognised as well as through the amortisation process.

Financial guarantee contracts

A financial guarantee contract is recognised initially at its fair value including transaction costs that are directly attributable to the issue of the guarantee. Subsequent to initial recognition, the liability is measured at the higher of the best estimate of the expenditure required to settle the present obligation at the reporting date and the amount recognised less cumulative amortisation.

Derecognition of financial liabilities

A financial liability is derecognised when the obligation under the liability is discharged, cancelled, or expires.

When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference between the respective carrying amounts is recognised in profit or loss.

Offsetting of financial instruments

Financial assets and liabilities are offset and the net amount reported in the consolidated statement of financial position, if and only if, there is a currently enforceable legal right to offset the recognised amounts and there is an intention to settle on a net basis, or to realise the assets and settle the liabilities simultaneously.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Inventories and supplies

Inventories primarily consist of oil and supplies, including items for repairs and maintenance of oil and gas properties. Inventories are stated at the lower of cost and net realisable value. Costs of inventories and supplies represent purchase or production cost of goods and are determined on a weighted average basis.

Cash and cash equivalents

Cash and cash equivalents comprise cash at banks and on hand and short term deposits with an original maturity of three months or less.

Provisions

 
(a)  
General

A provision is recognised when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation. When the effect of discounting is material, the amount recognised for a provision is the present value at the reporting date of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in "Finance costs" in profit or loss.

 
(b)  
Dismantlement liability

Dismantlement liability is recognised when the Group has a present legal or constructive obligation as a result of the past events, and it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the amount of the obligation can be made. A corresponding amount equivalent to the provision is also recognised as part of the cost of the related property, plant and equipment. The amount recognised is the estimated cost of dismantlement, discounted to its present value using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Changes in the estimated timing of dismantlement or dismantlement cost estimates are dealt with prospectively by recording an adjustment to the provision, and a corresponding adjustment to property, plant and equipment. The unwinding of the discount on the dismantlement provision is included as a finance cost.

Income tax

Income tax comprises current and deferred tax. Income tax is recognised in the consolidated statement of profit or loss and other comprehensive income, either as an expense as it relates to operating activities or as a component of the applicable categories of other comprehensive income or loss.

Current tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantially enacted, by the reporting date, in the countries where the Group operates and generates taxable income.

Deferred tax is provided, using the balance sheet liability method, on all temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Income tax (continued)

Deferred tax liabilities are recognised for all taxable temporary differences, except:

 
·  
when the deferred tax liability arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and
 
·  
in respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

As at December 31, 2014, deferred tax liabilities related to undistributed earnings of certain of the Company's subsidiaries have not been recognised, since the timing of the reversal of the taxable temporary difference can be controlled by the Company and it is probable that the temporary difference would not reverse in the foreseeable future.

Deferred tax assets are recognised for all deductible temporary differences, the carryforward of unused tax credits and any unused tax losses. Deferred tax assets are recognised to the extent that it is probable that taxable profit and taxable temporary differences will be available against which the deductible temporary differences, the carryforward of unused tax credits and unused tax losses can be utilised, except:

 
·  
when the deferred tax assets relating to the deductible temporary differences arise from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and
 
·  
in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are only recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Unrecognised deferred tax assets are reassessed at each reporting date and are recognised to the extent that it is probable that sufficient taxable profit and taxable temporary differences will be available to allow all or part of the deferred tax asset to be utilised.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Revenue recognition

Revenue is recognised when it is probable that the economic benefits will flow to the Group and when the revenue can be measured reliably, on the following bases:

 
(a)  
Oil and gas sales

Oil and gas sales represent the invoiced value of sales of oil and gas attributable to the interests of the Group, net of royalties, obligations to governments and other mineral interest owners. Revenue from the sale of oil and gas is recognised when the significant risks and rewards of ownership have been transferred, which is when title passes to the customer. Revenue from the production of oil and gas in which the Group has a joint interest with other producers is recognised based on the Group’s working interest and the terms of the relevant production sharing contracts. Differences between production sold and the Group’s share of production are not significant.

Oil and gas lifted and sold by the Group above or below the Group's participating interests in the production sharing contracts results in overlifts and underlifts. The Group records these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year-end oil prices. Settlement will be in kind or in cash when the liftings are equalised or in cash when production ceases.

The Group has entered into gas sale contracts with customers, which contain take-or-pay clauses. Under these contracts, the Group makes a long term supply commitment in return for a commitment from the buyer to pay for minimum quantities, whether or not it takes delivery. These commitments contain protective (force majeure) and adjustment provisions. If a buyer has a right to get a "make up" delivery at a later date, revenue recognition is deferred. If no such option exists according to the contract terms, revenue is recognised when the take-or-pay penalty is triggered.

 
(b)  
Marketing revenues

Marketing revenues principally represent the sales of oil and gas purchased from the foreign partners under the production sharing contracts and revenues from the trading of oil and gas through the Company’s subsidiaries. The cost of the oil and gas sold is included in “Crude oil and product purchases” in the consolidated statement of profit or loss and other comprehensive income. In addition, the Group’s marketing activities in North America involves entering into contracts to purchase and sell crude oil, natural gas and other energy commodities, and use derivative contracts, including futures, forwards, swaps and options for hedging and trading purposes (collectively derivative contracts). Any change in the fair value is also included in marketing revenue.

 
(c)  
Other income

Other income mainly represents project management fees charged to foreign partners, handling fees charged to customers and gains from disposal of oil and gas properties and is recognised when the services have been rendered or the properties have been disposed of. Reimbursement of insurance claims is recognised when the compensation becomes receivable.

 
(d)  
Dividend income

Dividend income is recognised when the Group's right to receive payment is established.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Revenue recognition (continued)

 
(e)  
Interest income

Interest income is recognised as it accrues using the effective interest method.

The Group presents taxes collected from customers in the consolidated statement of profit or loss and other comprehensive income on a net basis.

Share-based payment transactions

Employees (including directors) of the Group receive remuneration in the form of share-based payment transactions, whereby employees render services as consideration for equity instruments ("equity-settled transactions").

The cost of equity-settled transactions with employees is measured by reference to the fair value at the date at which they are granted. The fair value is determined by using the Black-Scholes option pricing model, further details of which are given in note 28.

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which the performance and/or service conditions are fulfilled. The cumulative expense recognised for equity-settled transactions at the end of the each reporting period until the vesting date reflects the extent to which the vesting period has expired and the Group's best estimate of the number of equity instruments that will ultimately vest. The charge or credit to profit or loss for a period represents the movement in the cumulative expense recognised as at the beginning and end of that period.

No expense is recognised for awards that do not ultimately vest for the Group.

No equity-settled award was cancelled or modified during the years ended December 31, 2014 and 2013.

The dilutive effect of outstanding options is reflected as additional share dilution in the computation of earnings per share.

Retirement and termination benefits

The Group participates in defined contribution plans in accordance with local laws and regulations for full-time employees in the PRC and other countries in which it operates. The Group's contributions to these defined contribution plans are charged to profit or loss in the year to which they relate.

Borrowing costs

Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds. Borrowing costs directly relating to the acquisition, construction or production of a qualifying asset that necessarily takes a substantial period of time to get ready for its intended use or sale are capitalised as part of the cost of the respective assets. All other borrowing costs are expensed in the period in which they are incurred.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Foreign currencies

These consolidated financial statements are presented in Renminbi ("RMB"). Each entity in the Group maintains its books and records in its own functional currency. Foreign currency transactions recorded by the entities of the Group are initially recorded using their respective exchange rates ruling at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated at the exchange rates ruling at the end of the reporting period. All differences arising on settlement or translation of monetary items are taken to profit or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. The gain or loss arising on retranslation of a non-monetary item is treated consistently with the recognition of the gain or loss on change in fair value of the item.

The functional currencies of certain entities within the Group are currencies other than RMB. As at the end of the reporting period, the assets and liabilities of these entities are translated into the presentation currency of the Group at the exchange rates ruling at the reporting date, and their statement of profit or loss and other comprehensive income are translated into RMB at the weighted average exchange rates for the year. The resulting exchange differences are included in the cumulative translation reserve. On disposal of a foreign operation, the deferred cumulative amount recognised in equity relating to that particular foreign operation is recognised in profit or loss.

Operating leases

Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Where the Group is the lessee, rentals payable under operating leases are charged to profit or loss on the straight-line basis over the lease terms.

Prepaid land lease payments under operating leases in China are initially stated at cost and subsequently amortised on the straight-line basis over the lease terms.

Contingencies

A contingent liability is disclosed when the existence of an obligation will only be confirmed by future events or when the amount of the obligation cannot be measured reliably.

A contingent asset is not recognised in the financial statements, but is disclosed when an inflow of economic benefits is probable.

Significant accounting judgements, estimates and assumptions

The preparation of the consolidated financial statements in conformity with IFRSs and HKFRSs requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates and judgements are continuously evaluated and are based on management's experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates.

In the process of applying the Group's accounting policies, the Directors have made the following judgements, estimates and assumptions, which have the most significant effect on the amounts recognised in the consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Significant accounting judgements, estimates and assumptions (continued)

 
(a)  
Reserve base

Oil and gas properties are depreciated on a unit-of-production basis at a rate calculated by reference to proved reserves. Commercial reserves are determined using estimates of oil in place, recovery factors and future oil prices, the latter having an impact on the proportion of the gross reserves which are attributable to the host government under the terms of the production sharing contracts. The level of estimated commercial reserves is also a key determinant in assessing whether the carrying value of any of the Group's oil and gas properties has been impaired.

Pursuant to the oil and gas reserve estimation requirements under US Securities and Exchange Commission's rules, the Group uses the average, first-day-of-the-month oil price during the 12-month period before the ending date of the period covered by the consolidated financial statements to estimate its proved oil and gas reserves.

 
(b)  
Carrying value of oil and gas properties

The calculation of the unit-of-production rate for oil and gas properties amortisation could be impacted to the extent that actual production in the future is different from current forecast production based on proved reserves. This would generally result from significant changes in any of the factors or assumptions used in estimating reserves. These factors could include changes in proved reserves, the effect on proved reserves of differences between actual commodity prices and commodity price assumptions and unforeseen operational issues.

 
(c)  
Impairment indicators

The recoverable amounts of cash-generating units and individual assets have been determined based on the higher of value in use and fair value less costs of disposal. These calculations require the use of estimates and assumptions. It is reasonably possible that the oil price assumption may change which may then impact the estimated life of the field and may then require a material adjustment to the carrying value of tangible and intangible assets. The Group monitors internal and external indicators of impairment relating to its tangible and intangible assets.

 
(d)  
Dismantlement costs

Dismantlement costs will be incurred by the Group at the end of the operating life of certain of the Group's facilities and properties. The ultimate dismantlement costs are uncertain and cost estimates can vary in response to many factors including changes to relevant legal requirements, the emergence of new restoration techniques or experience at other production sites. The expected timing and amount of expenditure can also change, for example, in response to changes in reserves or changes in laws and regulations or their interpretation. As a result, there could be significant adjustments to the provisions established which would affect future financial results.

Significant accounting judgements, estimates and assumptions (continued)

 
(e)  
Taxes

Uncertainties exist with respect to the interpretation of complex tax regulations (including those applicable to tax credits) and the amount and timing of future taxable income. Given the wide range of international business relationships and the long term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could necessitate future adjustments to tax income and expense already recorded. The Group establishes provisions, based on best estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as the Group's experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective group company's domicile.

ACQUISITIONS AND OTHER ARRANGEMENTS

2014

        The Group has no significant acquisition during the year.

2013

 
(i)
On July 23, 2012, the Company, CNOOC Canada Holding Ltd. and Nexen Inc. entered into an arrangement agreement in relation to the Company’s proposed acquisition (through its wholly-owned subsidiary, CNOOC Canada Holding Ltd.) of all the Nexen Inc. common shares and preferred shares, pursuant to a plan of arrangement under the Canada Business Corporations Act.

The acquisition of Nexen Inc. was completed on February 26, 2013 (Beijing time). The consideration of the acquisition was approximately US$14.8 billion (approximately RMB92.8 billion), and was paid in cash. The consideration is related to acquisition of common shares and preferred shares. As a result of the acquisition, an additional amount of approximately US$275 million was paid by Nexen Inc. to settle its long-term incentive plans. The indebtedness of Nexen Inc. at the acquisition date remains outstanding except for the US$460 million of subordinated debt that was repaid subsequently in 2013.

The MOF has decided to increase the threshold of the SOG Levy to US$55 with effect from November 1, 2011 and to further increase the threshold of the SOG Levy to US$65 with effect from January 1, 2015. Notwithstanding this adjustment, the SOG Levy continues to have five levels and is calculated and charged according to the progressive and valorem rates on the excess amounts.  The SOG Levy paid can be claimed as a deductible expense for corporate income tax purposes and is calculated based on the actual volume of the crude oil entitled.

TAX
 
 
(i)
Income tax
 
The Company and its subsidiaries are subject, on an entity basis, to income taxes on profits arising in or derived from the tax jurisdictions in which the entities of the Group are domiciled and operate. The Company is subject to profits tax at a rate of 16.5 % (2013: 16.5%, 2012: 16.5%) on profits arising in or derived from Hong Kong.

The Company is regarded as a Chinese Resident Enterprise (as defined in the "Enterprise Income Tax Law of the People's Republic of China") by the State Administration of Taxation of the PRC. As a result, the Company is subject to the PRC corporate income tax at the rate of 25% starting from January 1, 2008. The corporate income tax which is subjected in Hong Kong is qualified as a foreign tax credit to offset the PRC corporate income tax starting from January 1, 2008.

The Company's subsidiary in Mainland China, CNOOC China Limited, is a wholly-owned foreign enterprise. It is subject to corporate income tax at the rate of 25% under the prevailing tax rules and regulations.

Subsidiaries of the Group domiciled outside the PRC are subject to income tax at rates ranging from 10% to 62%.

As of December 31, 2014, deferred tax liabilities related to undistributed earnings of the Company's overseas subsidiaries have not been provided since the timing of the reversal of the taxable temporary differences can be controlled by the Company and it is probable that the temporary differences would not reverse in the foreseeable future.
 
An analysis of the tax expense in the Group's consolidated statement of profit or loss and other comprehensive income is as follows:

As at December 31, 2014, the Group had approximately RMB45,484 million (December 31, 2013: RMB34,422 million) of carry-forward tax losses, predominantly in North America, that would be available to offset against future taxable profits of the subsidiaries in which the tax losses arose. Most of the US and Canadian tax losses will expire in 10 to 20 years. The Uganda tax losses have no fixed expiry date.
 
Deferred tax assets in respect of tax losses are recognised only to the extent of the anticipated future taxable profits arising from the reversal of existing taxable temporary differences.

Pursuant to the Enterprise Income Tax Law of the People's Republic of China and related laws and regulations, the Company is regarded as a Chinese Resident Enterprise, and thus is required to withhold corporate income tax at the rate of 10% when it distributes dividends to its non-resident enterprise (as defined in the "Enterprise Income Tax Law of the People's Republic of China") shareholders, with effect from the distribution of the 2008 final dividend. In respect of all shareholders whose names appear on the Company's register of members and who are not individuals (including HKSCC Nominees Limited, corporate nominees or trustees such as securities companies and banks, and other entities or organizations, which are all considered as non-resident enterprise shareholders), the Company will distribute the dividend after deducting corporate income tax of 10%. The Company is in the process of discussing with relevant PRC authorities regarding the arrangement (if any) relating to the withholding tax in respect of dividend to be paid by the Company to the investors who invest in the shares in the Company listed on the Main Board of The Stock Exchange of Hong Kong Limited through the Shanghai Stock Exchange.

In addition, a letter of credit agreement was signed between the Company and Talisman with execution of the aforesaid agreement. Accordingly, Talisman has delivered valid and unexpired standby letters of credit with the amount of US$120 million to the Company (as the beneficiary) as a counter-guarantee to offset the exposure of the Company’s guarantee for the aforesaid interest of 3.05691% in respect of the Tangguh LNG Project financing. With the prepayment of portion of bank loans on January 31, 2014, the amount of the standby letters of credit decreased to US$30 million.

Share option schemes

The Company has adopted the share option schemes for the grant of options to the Company's directors, senior management and other eligible grantees.

 
(1)
Pre-Global Offering Share Option Scheme (expired in 2011);

 
(2)
2001 Share Option Scheme (expired in 2011);

 
(3)
2002 Share Option Scheme (as defined below); and

 
(4)
2005 Share Option Scheme (as defined below).

Under these share option schemes, the Remuneration Committee of the Board will from time to time propose for the Board's approval the grant of share options and the number of share options to be granted to the relevant grantees. The maximum aggregate number of shares (including those that could be subscribed for under the Pre-Global Offering Share Option Scheme, the 2001 Share Option Scheme, the 2002 Share Option Scheme and the 2005 Share Option Scheme) which may be issued upon exercise of all options granted shall not exceed 10% of the total issued share capital of the Company as at December 31, 2005, being the date on which the shareholders of the Company approved the 2005 Share Option Scheme, excluding shares under options which have lapsed.

2002 Share Option Scheme
In June 2002, the Company adopted a share option scheme (the "2002 Share Option Scheme") for the purpose of recognising the contribution that certain individuals had made to the Company and for attracting and retaining the best available personnel to the Company.

Share option schemes (continued)

2002 Share Option Scheme (continued)

Under the 2002 Share Option Scheme, the Board may, at its discretion, offer to grant to the directors and employees of the Company or any of its subsidiaries options to subscribe for shares of the Company. The maximum number of shares in respect of which options may be granted under the 2002 Share Option Scheme to any individual in any 12-month period up to the date of the latest grant shall not exceed 1% of the total issued share capital of the Company from time to time.

According to the 2002 Share Option Scheme, the consideration payable by a grantee for the grant of options will be HK$1.00. The exercise price for such options will be determined by the Board at its discretion at the date of grant, except that such price shall be not less than the higher of:

 
(1)
the nominal value of a share of the Company on the date of grant;

 
(2)
the average closing price of the shares as stated in the quotation sheets of the Stock Exchange of Hong Kong Limited (the "HKSE") for the five trading days immediately preceding the date of grant; and

 
(3)
the closing price of the shares as stated in the HKSE's quotation sheet on the date of grant.

The exercise periods for the options granted under the 2002 Share Option Scheme shall end not later than 10 years from the date of grant.

On December 31, 2005, the Company terminated the 2002 Share Option Scheme. Upon termination of the 2002 Share Option Scheme, no further options may be granted under the 2002 Share Option Scheme, but in all other respects the provisions of the 2002 Share Option Scheme shall remain in force. The outstanding options under the 2002 Share Option Scheme shall continue to be subject to the provisions of the 2002 Share Option Scheme.

2005 Share Option Scheme
On December 31, 2005, the Company adopted a new share option scheme (the "2005 Share Option Scheme"). Under the 2005 Share Option Scheme, the Board has the authority to grant options to subscribe for shares to the directors, officers and employees of the Company and its subsidiaries, and any other persons who in the sole discretion of the Board, have contributed or will contribute to the Group. Unless approved by the shareholders, the total number of shares issued and to be issued upon exercise of the options granted to each individual (including exercised and unexercised options) under the 2005 Share Option Scheme or any other share option scheme adopted by the Company, in any 12-month period, must not exceed 1% of the shares in issue of the Company.

According to the 2005 Share Option Scheme, the consideration payable by a grantee for the grant of options will be HK$1.00. The exercise price for such options will be determined by the Board at its discretion at the date of grant, except that such price shall be at least the higher of:

 
(1)
the nominal value of a share of the Company on the date of grant;

 
(2)
the average closing price of the shares as stated in the HKSE's daily quotation sheets for the five trading days immediately preceding the date of grant; and

 
(3)
the closing price of the shares as stated in the HKSE's daily quotation sheet on the date of grant.

Share option schemes (continued)

2005 Share Option Scheme (continued)

The period within which the options must be exercised, as well as any minimum holding period or performance targets which apply to the options, will be specified by the Board of the Company at the time of grant. The exercise periods for options granted under the 2005 Share Option Scheme shall end not later than 10 years from the date of grant. No options may be granted under the 2005 Share Option Scheme after the date of the 10th anniversary of the adoption of the 2005 Share Option Scheme.

No new share option was granted during the year (2013 and 2012: nil) and the Group recognised an equity-settled share option expense of nil (2013: RMB11 million, 2012: RMB50 million) during the year.

The fair value of equity-settled share options granted was estimated as at the date of grant if any, using the Black-Scholes option pricing model, taking into account the terms and conditions upon which the options were granted.

No share options had been cancelled or modified during the years ended December 31, 2012, 2013 and 2014.

At the date of approval of these consolidated financial statements, the share options outstanding under these share option schemes represented approximately 0.70% of the Company's shares in issue as at that date (2013: 0.86%, 2012: 0.92%). The weighted average remaining contractual life of share options outstanding at the end of the year was 3.50 years (2013: 4.23 years, 2012: 5.06 years). The exercise in full of the outstanding share options would, under the present capital structure of the Company, result in the issue of 311,184,000 additional ordinary shares of the Company and additional share capital of RMB2,497,193,648.

RESERVES

According to the laws and regulations of the PRC and the articles of association of CNOOC China Limited, CNOOC China Limited is required to provide for certain statutory funds, namely, the general reserve fund and the staff and workers' bonus and welfare fund, which are appropriated from net profit (after making up for losses from previous years), but before dividend distribution.

CNOOC China Limited is required to allocate at least 10% of its net profit as reported in accordance with the generally accepted accounting principles in the PRC ("PRC GAAP") to the general reserve fund until the balance of such fund reaches 50% of its registered capital. The general reserve fund can only be used, upon approval by the relevant authority, to offset against accumulated losses or to increase capital.

Appropriation to the staff and workers' bonus and welfare fund, which is determined at the discretion of the board of directors of CNOOC China Limited, is expensed as incurred under IFRSs/HKFRSs. The staff and workers' bonus and welfare fund can only be used for special bonuses or collective welfare of employees.

As at December 31, 2014, the general reserve fund amounted to RMB10,000 million (December 31, 2013: RMB10,000 million), representing 50% (2013: 50%) of the total registered capital of CNOOC China Limited.

In accordance with the "Temporary Regulation for Safety Expense Financial Management of Higher Risk Industry" and the implementation guidance issued by the MOF of the PRC, the Group is required to accrue a safety fund for its oil and gas exploration and production activities within the PRC by appropriating a portion of its net profit to other reserves based on its annual production from offshore China. Such reserve is reduced for expenses incurred to improve the safety conditions of oil and gas production. When the safety fund is fully utilised, additional expenses incurred for safety production purposes are charged directly to the profit or loss for the year. As of December 31, 2014, the Group's safety fund reserve under the PRC regulations amounted to nil (December 31, 2013: nil).

Coalbed Methane Resources Exploration and Development Cooperation Agreement with China United Coalbed Methane Corporation Limited
 
On August 3, 2012, CNOOC China Limited, a wholly-owned subsidiary of the Company, entered into the Coalbed Methane Resources Exploration and Development Cooperation Agreement (the "Cooperation Agreement") with China United Coalbed Methane Corporation Limited ("CUCBM") in connection with the exploration, development, production and sale of Coalbed Methane ("CBM") and CBM products within the contract areas (as defined in the Cooperation Agreement). The term of the Cooperation Agreement commences on the effective date and expires on the later of (i) 30 years from the effective date of the Cooperation Agreement, and (ii) the end of the production period of the last CBM field (as defined in the Cooperation Agreement) in the contract areas, unless otherwise agreed by CNOOC China Limited and CUCBM. The Cooperation Agreement and the transactions contemplated thereunder were approved by independent shareholders of the Company on August 21, 2012. As at the date of the Cooperation Agreement, CNOOC China Limited expected to incur total expenses of RMB9,933.3 million (being (1) RMB9,713.3 million for the initial three years of the five years' exploration period, plus (2) the minimum exploration costs of RMB220 million as required under the applicable PRC laws and regulations for the remaining two years of the exploration period).
 
As CUCBM is unable to fulfill its obligations under the Cooperation Agreement in respect of four CBM blocks (the "Relevant Blocks") which form part of the contract areas, CNOOC China Limited and CUCBM entered into a supplemental agreement on October 10, 2013, pursuant to which (i) the Relevant Blocks will be excluded from the contract areas; and (ii) CUCBM will indemnify in full CNOOC China Limited against any related loss, the amount of which will be determined by a third party appraising firm appointed by both parties. CNOOC China Limited and CUCBM have reached an agreement on the compensation for the losses of CNOOC China Limited related to such Relevant Blocks. As the Relevant Blocks were still at preliminary exploration stage, no revenue was generated and it is expected that the exclusion of the Relevant Blocks from the contract areas will not materially affect the expected profit in relation to the Cooperation Agreement.
 
CUCBM is a connected person of the Company, hence the Cooperation Agreement constitutes a connected transaction of the Company under the Listing Rules. As of December 31, 2014, the accumulated investment incurred by CNOOC China Limited was RMB896 million (December 31, 2013: RMB493 million).
 
The amount due to the parent company and amounts due from/to related parties are unsecured, interest-free and are repayable on demand, unless otherwise disclosed.

Contingencies

 
a.
With respect to Penglai 19-3 Oilfield Oil Spill Accidents (please refer to the Annual Reports and/or Interim Reports of the Company issued in or after 2012 for the background information), the Company is of the view that the Company’s obligations, if any, arising from the above mentioned accidents shall be determined in accordance with relevant laws and regulations, the production sharing contract ( the "PSC") and related agreements, among others. Based on evaluations performed as of the date of the consolidated financial statements authorized for issuance, the Company believes that it is not possible to determine provisions, if any, for the Company's obligation determined in the future arising from the above mentioned accidents in the consolidated financial statements. The financial impact of such oil spill accidents on the Company is still uncertain, and the Company has not made any provision for the accidents in the consolidated financial statements.

 
b.
On October 11, 2012, the Company was served with a purported class action complaint filed by Sam Sinay, individually and on behalf of all others similarly situated (the "Plaintiff") in the Unites States District Court for the Southern District of New York (the "Trial Court") (the foregoing legal action is therein below referred as the "Complaint"). The Complaint was lodged against the Company and certain of its officers, which alleged that during the period between January 27, 2011 and September 16, 2011, the Company made materially false and misleading statements regarding its business and financial results and the oil spill accidents occurred at the Penglai 19-3 oilfield.

 
On December 21, 2012, the Company filed a motion to dismiss the Complaint in the Trial Court.

 
On April 4, 2013, the judge of the Trial Court approved the Plaintiff’s voluntarily dismissal, without prejudice, to its claims against the officers of the Company.

 
On May 6, 2013, the judge of the Trial Court granted the Company’s motion to dismiss in the entirety with prejudice. On June 5, 2013, the Plaintiff (i.e. the Appellant) appealed to the United States Court of Appeals for the Second Circuit (the “Court of Appeals”). On February 3, 2014, the Court of Appeals issued a summary order which found the Appellant’s argument without merit and affirmed the Trial Court’s judgment. After the issuance of the summary order, the Appellant was able to appeal to the Supreme Court of the United States within 90 days (namely, on or before May 5, 2014, New York time) (the "Appeal Period"). The Appellant did not appeal within the Appeal Period. In accordance with the laws of the United States, all the claims brought by the Appellant at the Trial Court and the Court of Appeals are dismissed in their entirety.

 
c.
As a Chinese Resident Enterprise, the Company may be liable to pay taxes on the deemed interest income for the funding provided to its overseas subsidiaries starting from January 1, 2008. The Company has prepared contemporaneous documentation in accordance with applicable PRC tax laws and regulations and is currently awaiting confirmation from its in-charge tax authority.

COMMITMENTS AND CONTINGENCIES (continued)

 
(iii)
Contingencies (continued)

 
The Group is subject to tax in numerous jurisdictions around the world. There are audits in progress and items under review. Difference in positions taken by taxation authorities over the interpretation and application of tax laws and regulations may increase our tax liability. Management has assessed the possible future outcome of matters that are currently under dispute. The Company believes that an adequate provision for future tax liability has been included in the consolidated financial statements based on available information.

 
In addition to the matters mentioned above, the Group is dealing with a number of other lawsuits and arbitrations that arise in the ordinary course of business. While the results of these legal proceedings cannot be ascertained at this stage, the Company believes these proceedings are not expected to have a material effect on the consolidated financial statements.

FINANCIAL INSTRUMENTS

   Fair value of financial instruments

The Group enters into contracts to purchase and sell crude oil, natural gas and other energy commodities, and use derivative contracts, including futures, forwards, swaps and options for hedging and trading purposes (collectively derivative contracts). The Group also use derivatives to manage foreign currency risk for non-trading purposes. The total gains or losses in profit or loss for the year attributable to the realised and unrealised gains or losses relating to total derivative financial assets and liabilities that are included in "marketing revenues" is RMB1,030 million (2013: RMB1,667 million, 2012: nil).

For purposes of estimating the fair value of the derivative contracts, wherever possible, the Group utilises quoted market price and, if not available, estimates from third-party brokers. These brokers’ estimates are corroborated with multiple sources and/or other observable market data utilising assumptions that market participants would use when pricing the assets or liabilities, including assumptions about risk and market liquidity.

The carrying values of the Group’s cash and cash equivalents, time deposits, trade receivables, other current assets, trade and accrued payables, short-term loans, other payables and accrued liabilities approximated to their fair values at the reporting date due to the short maturity of these instruments.

The fair value of the Group's long term bank loans with floating interest rates approximated to the carrying amount as at December 31, 2014.

The estimated fair value of the Group's long term guaranteed notes based on current market interest rates was approximately RMB108,106 million as at December 31, 2014 (2013: RMB76,674 million), which was determined by reference to the market price as at December 31, 2014.

FINANCIAL INSTRUMENTS (continued)

Fair value hierarchy

The Group uses the following hierarchy that reflects the significance of the inputs used in making the fair value measurement:

Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities. Active markets are those in which transaction occur in sufficient frequency and volume to provide pricing information on an on-going basis.

Level 2: fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Instruments in this category include non-exchange traded derivatives such as over-the-counter physical forwards and options, including those that have prices similar to quoted market prices, private equity funds and corporate wealth management products. The Group obtains information from sources of independent price publications, over-the-counter broker quotes and the fund management’s quotations as at the reporting date.

Level 3: fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs), or where the observable data does not support the majority of the instruments fair value.

As at December 31, 2014 and December 31, 2013, the Group held the following financial instruments measured at fair value for each hierarchy respectively:

For financial assets and liabilities arising from derivative contracts, inputs may be readily observable, market-corroborated or generally unobservable. The Group utilises valuation techniques that seek to maximise the use of observable inputs and minimise the use of unobservable inputs. To value longer term transactions and transactions in less active markets for which pricing information is not generally available, unobservable inputs may be used. In these instances, internally developed methodologies are used to determine fair value, which primarily includes extrapolation of observable future prices to similar locations, similar instruments or later time periods. Key inputs are forward price of the underlying commodity, which may be observable or unobservable, discount rate and foreign exchange rates. The derivatives are classified according to the above fair value hierarchy based on the amount of observable inputs used to value the instruments. For derivatives categorised within level 3 of the fair value hierarchy, the significant unobservable inputs used in the fair value measurement includes the extrapolation of future price of commodity.

No amounts have been transferred between the different levels of the fair value hierarchy for the year.

A reconciliation of changes in the fair value of the derivatives classified as Level 3 for the year ended December 31, 2014 and 2013 is provided below:

    (5 )     -

Items classified in Level 3 are generally economically hedged such that gains or losses on positions classified in Level 3 are often offset by gains or losses on positions classified in Level 1 or Level 2. The Group performed a sensitivity analysis of inputs used to calculate the fair value of Level 3 instruments. Using reasonably possible alternative assumptions, the fair value of Level 3 instruments at December 31, 2014 would have no material change.

FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES

The Group's principal financial instruments comprise bank loans, long term guaranteed notes, available-for-sale financial assets, cash and short term deposits. The Group has various other financial assets and liabilities such as trade receivables, trade and accrued payables, which arise directly from its operations.

The Group is exposed to credit risk, oil and gas price risk, currency risk, interest rate risk and liquidity risk.

The Group's senior management oversees the management of these risks. The Group's senior management is supported by various departments that advise on financial risks and the appropriate financial risks governance framework for the Group. Those departments provide assurance to the Group's senior management that the Group's financial risk-taking activities are governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with group policies and group risk appetite.

 
(i)
Credit risk

The carrying amounts of the Group's cash and cash equivalents, time deposits, liquidity funds investments and corporate wealth management products, trade receivables and other receivables, and other current assets except for prepayments represent the Group's maximum exposure to credit risk in relation to its financial assets.

The significant portion of the Group's trade receivables is related to the sale of oil and natural gas to third party customers. The Group performs ongoing credit evaluations of the customers' financial condition and collateral may be required from customers. The Group made an impairment allowance on doubtful receivables and actual losses have been within management's expectation.

Concentrations of credit risk are managed by customer/counterparty and by geographical region. At December 31, 2014, the Group has certain concentrations of credit risk as 11% (2013: 9%) and 15% (2013: 14%) of the Group's trade receivables were due from the Group's largest third-party customer and the five largest third-party customers, respectively.

No other financial assets carry a significant exposure to credit risk.

FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES (continued)

 
(ii)
Oil and gas price risk

Since the Group makes reference to international oil prices to determine its realised oil price, fluctuations in international oil price would have a significant impact on the Group's sales revenue and profit. In addition, certain of the Group's natural gas sales contracts contain price adjustment provisions. Any changes in international oil prices, inflation rate and domestic natural gas price policies may result in changes in natural gas prices, which will affect the Group's profitability. In North America, the majority of the Group's oil and gas production is sold under short-term contracts, exposing the Group to the risk of price movements. Other energy contracts the Group enters into also expose the Group to commodity price risk between the time the Group purchases and sells contracted volumes.

 
(iii)
Currency risk

Substantially all of the Group's oil and gas sales are denominated in Renminbi and United States dollars ("US dollars"). Starting from July 21, 2005, China reformed the exchange rate regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. Renminbi would no longer be pegged to the US dollars. From January 1, 2014 to December 31, 2014 (the last working day in 2014), Renminbi has depreciated by approximately 0.36% against the US dollars. At December 31, 2014, approximately 79% (December 31, 2013: 79%, December 31, 2012: 92%) of the Group's cash and cash equivalents and time deposits with maturity over three months were denominated in Renminbi, and the remaining amounts were substantially denominated in US dollars and Hong Kong dollars. We also have exposures to currencies other than the US dollars, such as Canadian dollar and British Pounds as such exposures are considered insignificant.

Management has assessed the Group's exposure to foreign currency risk by using a sensitivity analysis on the change in foreign exchange rate of the US dollars, to which the Group is mainly exposed to as at December 31, 2013 and 2014. Based on management's assessment, a 5% change in the foreign exchange rate of the US dollars at December 31, 2014 would have impacted the profit for the year of the Group by 0.06% (December 31, 2013: 0.35%) and the equity of the Group by 0.50% (December 31, 2013: 0.07%). This analysis has been determined assuming that the change in foreign exchange rates had occurred at the end of the reporting period and had been applied to the foreign currency balances to which the Group has significant exposure with all other variables held constant.  The analysis is performed on the same basis for 2013.

Senior management are closely monitoring the Group's net exposure to foreign currency risk. The depreciation of Renminbi against the US dollars may have the following impact on the Group. On one hand, since the benchmark oil and gas prices are usually in US dollars against Renminbi, the Group's oil and gas sales may increase due to the appreciation of the US dollars against Renminbi. On the other hand, the appreciation of the US dollars against Renminbi will also increase the Group's costs for imported equipment and materials, most of which are denominated in the US dollars. In addition, the debt repayment by the Group will increase since all of the Group's debts are also denominated in the US dollars.

 
(iv)
Interest rate risk

The interest rate risk is closely monitored by the Group's senior management. As at the end of 2014, the interest rates for 79.2% of the Group's debts were fixed. Apart from borrowing for Tangguh LNG Project, all of the Group's long term debts are fixed rate. The weighted average term of the Group's debt balance outstanding was approximately 9.5 years. The fixed interest rates can reduce the volatility of finance costs under uncertain environments and the Group's exposure to changes in interest rates is not expected to be material.

FINANCIAL RISK MANAGEMENT OBJECTIVES AND POLICIES (continued)

 
(v)
Liquidity risk

The Group manages its liquidity risk by regularly monitoring its liquidity requirements and its compliance with debt covenants to ensure that it maintains sufficient cash and cash equivalents, and readily realisable available-for-sale financial assets, and adequate time deposits to meet its liquidity requirements in the short and long term. In addition, bank facilities have been put in place for contingency purposes.

The Group's trade and accrued payables, other payables and accrued liabilities are all due for settlement within six months after the reporting date.

 
(vi)
Capital management

The primary objectives of the Group's capital management are to safeguard the Group's ability to continue as a going concern and to maintain healthy capital ratios in order to support its business and maximise shareholders' value.

The Group manages its capital structure and makes adjustments to it in light of changes in economic conditions. To maintain or adjust the capital structure, the Group may return capital to shareholders, raise new debt or issue new shares. No changes were made in the objectives, policies or processes for managing capital during the years end December 31, 2012, 2013 and 2014.

The Group monitors capital on the basis of the debt to capital ratio, which is calculated as interest-bearing debts divided by total capital (equity attributable to owners of the parent plus interest-bearing debts).

(All amounts expressed in millions of Renminbi unless otherwise stated)
 
The following disclosures are included in accordance with the FASB Accounting Standard Codification 932 “Extractive Activities-Oil and Gas (the “ASC 932”).
 
The regional analysis presented below is on a continent basis, with separate disclosure for countries that contain 15% or more of the total proved reserve, in accordance with SEC and FASB requirements.
 
(a) 
Reserve quantity information
 
 
Crude oil and natural gas reserve estimates are determined through analysis of geological and engineering data which appear, with reasonable certainty, to be economically producible in the future from known oil and natural gas reservoirs under existing economic and operating conditions. The reserve data that we disclosed were all based on the definitions and disclosure guidelines contained in the US Securities and Exchange Commission’s final rules on “Modernization of oil and Gas Reporting” (the “SEC Final Rule”).
 
 
For the years 2014, 2013 and 2012, approximately 52%, 52% and 36%, respectively, of our total proved reserves were evaluated by us, and the remaining were evaluated by independent third parties.
 
 
We implemented rigorous internal control system that monitors the entire reserves estimation process and certain key metrics in order to ensure that the process and results of reserves estimates fully comply with the relevant SEC rules.
 
 
We established the Reserve Management Committee, or RMC, which is led by one of our Executive Vice Presidents and comprises the general managers of the relevant departments.
 
 
 
 
·
review our reserves policies;
 
 
·
review our proved reserves and other categories of reserves; and
 
 
·
select our reserves estimators and auditors.

SUPPLEMENTARY INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES
(UNAUDITED)
(All amounts expressed in millions of Renminbi unless otherwise stated)
 
(a) 
Reserve quantity information (continued)

The RMC follows certain procedures to appoint our internal reserves estimators and reserves auditors, who are required to have undergraduate degrees and at least five years and ten years of experience related to reserves estimation, respectively.

The reserves estimators and auditors are required to be members of a professional society, such as China Petroleum Society (CPS), and are required to take the professional trainings and examinations as required by the professional society and us.

The RMC delegates its daily operation to our Reserves Office, which is led by our Chief Reserve Supervisor. The Reserves Office is mainly responsible for supervising reserves estimates and auditing. It reports to the RMC periodically and is independent from operating divisions such as the exploration, development and production departments. Our Chief Reserve Supervisor has more than 30 years’ experience in oil and gas industry.

The Group’s net proved reserves consist of its interest in reserves, comprised of a 100% interest in its independent oil and gas properties and its participating interest in the properties covered under the production sharing contracts in the PRC, less (i) an adjustment for the Group’s share of royalties payable by the Group to the PRC government and the Group’s participating interest in share oil payable to the PRC government under the production sharing contracts, and less (ii) an adjustment for production allocable to foreign partners under the PRC production sharing contracts as reimbursement for exploration expenses attributable to the Group’s participating interest, and plus the participating interest in the properties covered under the production sharing contracts in oversea countries, less adjustments, if any, of share oil attributable to the host government and the domestic market obligation.

Pursuant to SEC Final Rule, the Group uses the average, first-day-of-the-month oil price during the 12-month period before the ending date of the period covered by the consolidated financial statements to estimate its proved oil and gas reserves.

The Company determines its net entitlement oil and gas reserves under production sharing contracts using the economic interest method.

(e) 
Standardised measure of discounted future net cash flows and changes therein

Pursuant to FASB Topic 932, the average of first-day-of-the-month oil price during the 12-month period before the year end, were used to estimate annual future production fromm proved reserves to determine future cash inflows.

Future development costs are estimated based upon constant price assumptions and the assumption of the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying the year-end statutory rate to estimate future pre-tax cash flows after provision for the tax cost of the oil and natural gas properties based upon existing laws and regulations. The discount was computed by the application of a 10% discount factor to the estimated future net cash flows.

Management believes that this information does not represent the fair market value of the oil and natural gas reserves or the present value of estimated cash flows since no economic value is attributed to potential reserves, the use of a 10% discount rate is arbitrary, and prices change constantly.

Present value of estimated future net cash flows:
