TABLE OF CONTENTS
PART I
ITEM 1. BUSINESS
Macquarie Infrastructure Holdings, LLC ("MIH") is a Delaware limited liability company formed on February 5, 2021 and the registrant since September 22, 2021. MIH is the successor to Macquarie Infrastructure Corporation ("MIC"), a Delaware corporation formed on May 21, 2015. MIC’s predecessor, Macquarie Infrastructure Company LLC, was formed on April 13, 2004. Except as otherwise specified, all references in this Form 10-K to “MIH”, “we”, “us”, “our” and "Company" refer to Macquarie Infrastructure Holdings, LLC and its subsidiaries, or as necessary when referring to previous reporting periods or the period prior to September 22, 2021, MIC and its subsidiaries. The terms "unit", "equity interest", "stock", "security", or "shares" refers to shares of MIC prior to the Reorganization on September 22, 2021, and "units" in MIH thereafter.
Strategic Alternatives
In October 2019, along with actively managing our existing portfolio of businesses, our Board resolved to pursue strategic alternatives including the potential sale of our Company or its then three operating businesses as a means of unlocking additional value for equity holders. In December 2020, we completed the sale of IMTT ("IMTT Transaction").
On June 7, 2021, we entered into an agreement for the sale of our Atlantic Aviation business to KKR Apple Bidco, LLC, a Delaware limited liability company controlled by funds affiliated with Kohlberg Kravis Roberts & Co. L.P. (“KKR”), for $4.475 billion including cash and the assumption of debt and other transaction and reorganization related obligations (the "AA Transaction").
On June 14, 2021, we entered into a Merger Agreement with AMF Hawaii Holdings, LLC ("AMF Parent"), a Delaware limited liability company affiliated with Argo Infrastructure Partners, LP ("Argo"), and AMF Hawaii Merger Sub, LLC ("AMF Merger Sub"), a recently formed Delaware limited liability company and wholly-owned direct subsidiary of AMF Parent (the "Merger"). Upon completion of the Merger, each of the MIH common units (excluding common units held by AMF Parent or AMF Merger Sub or common units held by MIH in treasury and common units held by any subsidiary of MIH or AMF Parent (other than AMF Merger Sub)), will be converted into the right to receive $3.83 in cash, without interest; or, if the Merger is consummated after July 1, 2022, then each such unit will be converted into the right to receive $4.11 in cash, without interest.
Under the terms of the Merger Agreement, at closing, AMF Parent will pay the merger consideration to unitholders and fund transaction costs and a disposition payment to our Manager of $81.7 million if the Merger closes on or before July 1, 2022 or $56.7 million if the Merger closes after this date.
On September 21, 2021, we conducted a Special Meeting of Shareholders during which shareholders voted on and approved the AA Transaction and the Merger. As a result of the approval, we classified our Atlantic Aviation business as a discontinued operation.
On September 22, 2021, shareholders of Macquarie Infrastructure Corporation became unitholders of Macquarie Infrastructure Holdings, LLC, a limited liability company treated as a partnership for tax purposes, on a one-for-one basis without an exchange of certificates. Commencing September 23, 2021, units of Macquarie Infrastructure Holdings, LLC traded on the New York Stock Exchange ("NYSE") under the same symbol (NYSE: MIC) and with the same CUSIP number (55608B105) as previously associated with shares of Macquarie Infrastructure Corporation.
As part of the reorganization, the entity holding the businesses comprising our MIC Hawaii segment was distributed to and became a direct subsidiary of Macquarie Infrastructure Holdings, LLC. For tax purposes, the distribution was deemed to be a sale and unitholders were deemed to have received a distribution of the fair market value of the equity of MIC Hawaii.
On September 23, 2021, we completed the AA Transaction, and received $3.525 billion. Our Board elected to return certain proceeds from the AA Transaction to unitholders, declaring a one-time distribution of $37.386817 per common unit, paid on October 7, 2021 to unitholders of record as of the close of trading on October 4, 2021. The Company's common units traded with due-bills attached from October 1, 2021 through October 7, 2021 pursuant to relevant NYSE rules. In addition, MIH made a disposition payment to the Manager of $228.6 million.
The Merger is expected to be completed in the first half of 2022 subject to approval by the Hawaii Public Utilities Commission ("HPUC") and the satisfaction of customary closing conditions for this type of transaction. Upon the consummation of the Merger, our Company will no longer be a publicly traded entity.
Our Strategy
Our strategy is to realize value for our unitholders by completing the Merger, or an alternate transaction to the extent that the Merger is not ultimately successful.
From an operational perspective, our strategy centers on ensuring that we continue to provide quality products to our customers in a safe and reliable manner that over the long term is consistent with Hawaii’s goals of carbon neutrality by 2045.

TABLE OF CONTENTS
General
We provide products to corporations, government agencies, and individual customers in Hawaii. Our business comprises: (i) Hawaii Gas, Hawaii’s only government-franchised gas utility and an unregulated LPG distribution business providing gas and related services to industrial, commercial, residential, and governmental customers; (ii) controlling interests in two solar facilities on Oahu; and (iii) smaller projects collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii.
During the quarter ended September 30, 2021, Atlantic Aviation was classified as a discontinued operation and eliminated as a reportable segment. All prior periods reported herein reflect this change. In September 2021, we completed the AA Transaction.
During the quarter ended September 30, 2020, IMTT was classified as a discontinued operation and eliminated as a reportable segment. All periods reported herein reflect this change. In December 2020, we completed the IMTT Transaction.
Effective October 1, 2018, the Bayonne Energy Center (BEC) and substantially all of our portfolio of solar and wind power generation businesses were classified as discontinued operations and our Contracted Power segment was eliminated. All periods reported herein reflect this change. In September 2019, we completed the last of the sales of our solar and wind power generation businesses including our majority interest in a renewable power development business. A relationship with a third-party developer of renewable power facilities was reported as a component of Corporate and Other through the expiration of the relationship in July 2019.
Our Manager
Macquarie Infrastructure Management (USA) Inc. (our "Manager") serves as the external manager of our Company. Together we are parties to a Management Services Agreement (see Exhibit 10.1 of this Form 10-K) pursuant to which our Manager provides corporate headquarters functions and services to the Company. Our Manager is a member of the Macquarie Group, a diversified international provider of financial, advisory, and investment services. The Macquarie Group is headquartered in Sydney, Australia and is a global leader in the management of infrastructure investment vehicles on behalf of third-party investors and an advisor on the acquisition, disposition, and financing of infrastructure assets.
We pay our Manager a monthly base management fee of 1/12th of 1% of our equity market capitalization less any cash balances at the holding company. For this, in accordance with the Management Services Agreement, our Manager provides normal ongoing corporate headquarters functions such as executive management, facilities, technology, employee benefits and access to services including human resources, legal, finance, tax and accounting, among others. Our Manager is responsible for and oversees the management of our business, subject to the oversight and supervision of our Board. Our Manager compensates and has assigned, or seconded, to us our chief executive officer and chief financial officer on a full-time basis. It also compensates and seconds, or makes available, other personnel as required. MIH has no employees at the holding company level.
Our Manager may also earn a performance fee if our quarterly total return (capital appreciation plus distributions) is positive and exceeds the quarterly total return of a U.S. utilities index benchmark both in the quarter and cumulatively. If payable, the performance fee is equal to 20% of the difference between the benchmark return and the total return for our stockholders during the quarter. Per the terms of the Management Services Agreement, our Manager currently reinvests any base management or performance fees in new primary common units of our Company. Our Manager may elect to receive either base management or performance fees, if any, in cash but may only change its election during a 20-trading day window following our earnings release. Any change would apply to fees to which it was entitled thereafter.
To facilitate our pursuit of strategic alternatives, on October 31, 2019, we announced that we entered into a Disposition Agreement ("Disposition Agreement") with our Manager (see Exhibit 10.3 of this Form 10-K). Outside of this agreement, we have limited ability to terminate the Management Services Agreement. With this agreement, our Management Services Agreement with our Manager will terminate as to any businesses, or substantial portions thereof, that are sold and, in connection therewith, we will make payments to our Manager calculated in accordance with the Disposition Agreement. The Disposition Agreement will terminate on the earlier to occur of (i) the termination of the Management Services Agreement and (ii) the sixth anniversary of the Disposition Agreement, subject to extension under certain circumstances if a sale transaction is pending. In connection with the execution of the Merger Agreement, on June 14, 2021, the Company and the Manager entered into an amendment to the Disposition Agreement providing for the calculation of the disposition payment payable to the Manager with respect to the Merger, and providing that the Management Services Agreement will terminate concurrent with the closing of the Merger and payment of all amounts payable to the Manager under the Disposition Agreement.

TABLE OF CONTENTS
Our Business
Industry Overview
According to the Energy Information Administration, energy consumption in Hawaii is split approximately equally between the transportation market and the industrial/commercial/residential markets. Gas has an approximately 2% share of the Hawaii energy market and is used primarily by the industrial/commercial/residential markets with applications including water heating, commercial laundry service, cooking, emergency power generation, and other select uses.
Beginning with the Hawaii Clean Energy Initiative in 2008, the State of Hawaii embarked on a program to be a leader in the development and deployment of clean energy solutions. We have invested in a number of clean energy projects including a renewable natural gas facility that captures and purifies wastewater biogas for injection into the Hawaii Gas utility pipeline on Oahu. We are pursuing additional growth opportunities in support of Hawaii’s clean energy goals.
Business Overview
Our business comprises Hawaii Gas and smaller operations collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii. Founded in 1904, Hawaii Gas is a combination of Hawaii’s only government-franchised gas utility and an unregulated liquefied petroleum gas ("LPG") distribution business. Hawaii Gas serves the State’s approximately 1.4 million residents and approximately 6.8 million and 2.7 million visitors in 2021 and 2020, respectively, across Oahu, Hawaii, Maui, Kauai, Molokai, and Lanai (the main islands). Visitor arrivals for 2021 and 2020 were substantially lower than in prior years due to the outbreak of COVID-19. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Results of Operations” for further discussions.
Hawaii Gas’ utility business includes the processing, distribution, and sale of synthetic natural gas ("SNG") and renewable natural gas ("RNG") and the distribution and sale of regasified liquefied natural gas ("LNG") on the island of Oahu, as well as the distribution and sale of LPG via pipeline on all of the main islands. Hawaii Gas’ unregulated business distributes LPG by truck to individual tanks located on customer sites or distributes LPG in cylinders filled at central locations to customers on all the main islands. Customers include a wide variety of industrial, commercial, residential, hospitality, military, public sector, and wholesale users.
Hawaii Gas’ primary products consist of:
Synthetic Natural Gas: The business converts a light hydrocarbon feedstock (naphtha) into SNG, predominantly comprised of methane and hydrogen, having a similar heating value to natural gas. Hawaii Gas operates the only SNG processing capability in Hawaii at its plant located on the island of Oahu. SNG is delivered by underground pipelines to utility customers throughout Oahu.
Liquefied Natural Gas: LNG is transported to Hawaii in conventional intermodal cryogenic containers from the U.S. mainland. Hawaii Gas is authorized to substitute up to 30% of its SNG production with LNG to supply customers of the regulated utility on Oahu.
Liquefied Petroleum Gas: LPG is a generic name for a mixture of hydrocarbon gases, typically propane and butane. LPG liquefies at a relatively low pressure under normal temperature conditions and can be efficiently transported in various quantities. LPG is typically stored in cylinders or tanks and Hawaii Gas maintains the largest network of LPG storage in Hawaii. Industrial/commercial/residential applications of LPG are similar to those of natural gas and SNG.
Renewable Natural Gas: Hawaii Gas collects, purifies, and injects biogas from the Honouliuli Wastewater Treatment Plant into the utility pipeline distribution system on Oahu. The business is evaluating a range of additional renewable natural gas sources including other wastewater treatment plants, landfills, and locally produced biomass.
Customers
Our business provides services to industrial, commercial, residential, hospitality, military, public sector, wholesale and governmental customers and do not depend on any single customer, the loss of which would have a material adverse effect on the business.
Regulation
Our utility operations are regulated by the HPUC. The HPUC exercises broad regulatory oversight and investigative authority over all public utilities in Hawaii.
Rate Regulation. The HPUC establishes the rates that Hawaii Gas can charge its utility customers via cost of service regulation. Although the HPUC sets the base rate for the gas sold by Hawaii Gas’ utility business, Hawaii Gas is permitted to pass through changes in its fuel (feedstock) costs by means of a monthly fuel adjustment charge.
5

TABLE OF CONTENTS

Our utility rates are established by the HPUC in periodic rate cases typically initiated by Hawaii Gas. We initiate a rate case by submitting a request to the HPUC for an increase in rates based upon, for example, increased costs related to providing services. Following initiation of the rate increase request and submissions by other intervening parties of their positions on the rate request, and potentially an evidentiary hearing, the HPUC issues a decision establishing the revenue requirements and the resulting rates that our utility will be allowed to charge.
Other Regulations. In addition to regulating utility rates, the HPUC acts on requests for the acquisition, the sale, disposition, or other exchange of utility properties, including mergers and consolidations, acts on requests for financings and approves material supply contracts.
Our operations are also regulated by agencies including the Pipeline and Hazardous Materials Safety Administration, Department of Transportation, Environmental Protection Agency, Hawaii Department of Health, and state and local environmental agencies.
Competition
Depending upon the end-use, Hawaii Gas competes with electricity producers and distributors as well as other gas providers, diesel, and other alternative energy sources. Electricity in Hawaii is generated by four electric utilities, various independent power producers, and commercial and residential solar installations.
Utility Operations. Hawaii Gas holds the only government franchise for utility gas services in Hawaii. This enables Hawaii Gas to utilize public easements for its pipeline distribution systems. This franchise also provides for the exclusive use of extensive below-ground distribution infrastructure that Hawaii Gas owns and maintains. Hawaii Gas competes based on price, reliability, and the energy preferences of its customers.
Non-Utility Operations. Hawaii Gas sells LPG in an unregulated market on the main islands of Hawaii. There are several other wholesale and smaller retail distributors that compete in the LPG market. Hawaii Gas believes it has a competitive advantage because of its established customer base, substantial storage facilities, distribution network, and reputation for reliable service.
Fuel Supply, SNG Plant, and Distribution System
Fuel Supply
Hawaii Gas sources naphtha feedstock for its SNG plant from Par Hawaii Refining, LLC pursuant to a contract that expires in December 2023. The majority of Hawaii Gas’ LPG is purchased from an off-island supplier pursuant to a contract that expires in December 2024. Hawaii Gas sources LNG from a U.S. mainland supplier pursuant to a contract that expired in July 2021, for which an extension is currently being negotiated. RNG feedstock is purchased from the City and County of Honolulu under a fixed rate contract that expires in December 2024.
SNG Plant and Distribution System (Utility)
Hawaii Gas processes and distributes SNG from a plant located on the west side of Oahu. A 22-mile transmission pipeline links the SNG plant to a distribution system consisting of approximately 900 miles of distribution and service pipelines transports gas to customers. On islands other than Oahu, LPG is distributed by direct deliveries from an off-island shipper and by barge from Oahu to holding facilities or baseyards on those islands. It is then distributed via pipelines to utility customers. Approximately 90% of the Hawaii Gas pipeline system is on Oahu.
Distribution System (Non-Utility)
The non-utility operation of Hawaii Gas provides LPG to customers that are not connected to Hawaii Gas’ utility pipeline system on each of the main islands. The majority of Hawaii Gas’ non-utility customers are on islands other than Oahu. LPG is transported to these islands by direct deliveries from an off-island shipper and by barge from Oahu. Hawaii Gas also owns the infrastructure by which it distributes LPG to its customers, including harbor pipelines, trucks, several holding facilities, and storage baseyards on Kauai, Maui, and Hawaii.
Environmental Permits
We require environmental operating permits, the most significant of which are air and wastewater permits required for the Hawaii Gas SNG plant.
Human Capital Management
As of December 31, 2021, we employed 354 employees, of which 215 employees, or 61%, were subject to collective bargaining agreements. We believe relations with both union and non-union employees are generally good, that these employees drive the success of our business and that supporting our employees is a foundational value of the Company.

TABLE OF CONTENTS

Our ultimate parent company has no employees as our Manager employs and seconds those individuals who serve as our chief executive officer and chief financial officer on a full-time basis and makes other personnel available as required.
Business ethics. Our continued success relies on the preservation of our good reputation. Our Code of Business Conduct sets forth our commitment to safe, ethical, and legally compliant business practices, and outlines the values by which all employees are expected to be guided.
Health and safety. We promote a “zero harm” culture. The workplace health and safety performance of our business is reported regularly to our board of directors. Our business has implemented comprehensive safety training programs for employees and regularly review and enhance safety protocols. In 2020, in response to the COVID-19 pandemic, our business implemented pandemic response plans including remote working where possible and deployment of personal protective equipment and provided continuous communication to employees regarding steps they could take to protect themselves. To the extent permitted/possible, we are facilitating the vaccination of our employees against COVID-19.
Compensation and benefits. Our business offers market competitive compensation programs in order to attract and retain superior talent, including bonus opportunities, health and welfare benefits, wellness initiatives, time-off, employee assistance programs, and opportunities to give back to our communities through donations of time and money.
Culture and inclusion. We are an equal opportunity employer, and we are committed to fostering a diverse, inclusive, and empowered workforce. We have established a Diversity, Equity, and Inclusion committee and a women's network committee. These committees have been responsible for, among other things, conducting surveys of various employee groups on issues of diversity, equity, and inclusion and educating employees at all levels about the importance of having an employee and management team that reflect the composition of the communities they serve.

TABLE OF CONTENTS
ITEM 1A. RISK FACTORS
An investment in our units involves risks. The occurrence of any of these risks could have a significant or material adverse effect on our results of operations, cash flows, or financial condition and could cause a corresponding decline in the market price of our units.
Strategic and Economic Risks
If the pending Merger of the Company is not completed, our strategy as an ongoing business will require growth capital expenditures and a failure to make such capital expenditures could have a material adverse effect on our business, financial condition, operating results, and prospects.
If the pending Merger of the Company is not successful, and an alternate transaction is not pursued and completed, our growth will continue to depend on the prudent deployment of capital. Our ability to deploy capital depends on a number of variables including: (i) commodity prices; (ii) customer demand; (iii) competitive and economic conditions; (iv) availability of suitable land on which to operate; (v) ability to obtain required regulatory approvals; and (vi) availability of capital. Our sources of growth capital include retained capital, debt or equity issuances, and/or proceeds from the sales of assets. We may not generate sufficient cash or be able to arrange additional financing to fund our future growth needs on terms acceptable to us or at all. Our ability to arrange financing, if needed, will depend on, among other factors, our credit ratings, leverage, financial and operating performance, general economic, financial, and regulatory conditions, and prevailing capital market conditions. Many of these factors are beyond our control. If we incur significant additional indebtedness, our borrowing costs and our ability to raise capital may be impacted by our then credit rating which could be adversely affected if we do not continue to generate sufficient cash from our operations. If we fail to deploy growth capital as planned, we may be unable to, among other things, expand to meet competitive challenges; take advantage of strategic growth opportunities; upgrade our facilities and systems; and create equity holder value. Any or all of these could have a material adverse effect on our financial condition, operating results, tax positions, and prospects.
The pending Merger is contingent on a number of conditions and may not be completed timely or at all.
The consummation of the Merger is subject to various conditions, including, among others, receipt of regulatory approvals. If the Merger is not completed for any reason, the price of our common units may decline and our business, financial condition and results of operations may be impacted, including: to the extent that the market price of our common units reflects assumptions that the Merger will be completed; based on the significant expenses, such as legal and financial advisory services, which generally must be paid regardless of whether the Merger is completed; and due to the risk that we may be unable to enter into an alternative transaction for the sale of our business on terms as favorable as the Merger or at all. We may receive a termination fee under certain circumstances, but such fee may not adequately compensate us for our losses if the Merger is not completed. In addition, we may be required to pay a termination fee to the purchaser if the Merger Agreement is terminated under certain circumstances.
While the Merger is pending, the Company will be subject to risks and uncertainties and contractual restrictions that could disrupt our business or negatively impact our common unit price.
The announcement and pendency of the Merger could cause disruptions and create uncertainty surrounding our business and affect relationships with customers, suppliers and business partners. These uncertainties could cause customers, suppliers and others that deal with us to seek to change existing business relationships. In addition, employee retention could be negatively impacted during the pendency of the Merger. Pending completion of the Merger, the attention of our management may be focused on the Merger and related matters, and diverted from other opportunities that might benefit us. In addition, pursuant to the Merger Agreement, prior to closing we have agreed to conduct our business in the ordinary course and not to undertake certain actions without the written consent of the purchaser. These restrictions could prevent us from pursuing certain beneficial business opportunities. All of these uncertainties could adversely affect our business, financial condition and results of operations, and could negatively impact the market price of our common units.
As a result of prior sales of operating businesses we have fewer assets and the size of our Company may be sub-scale and more susceptible to adverse events.
Since the completion of the AA Transaction, the size of our Company may be sub-scale for a public company owner of a part regulated gas utility/part liquefied petroleum gas distribution business, and we may have limited access to financing through the capital markets due to our size. We are subject to concentration of risks. We have substantially fewer assets and may experience significant decreases in earnings and cash flow and increases in operating costs or other expenses. We continue to be a public company with ongoing costs associated with public company operations, which are a greater percentage of our revenues, and we are unlikely to recover all of those expenses from rate payers of our regulated utility, Hawaii Gas. The market price of our common units has significantly decreased, and our common units may be more susceptible to market fluctuations.
9

TABLE OF CONTENTS
Non-U.S. holders of common units may be subject to U.S. federal income tax and U.S. withholding tax upon their participation in the Merger.
In general, under the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA") provisions of the United States Internal Revenue Code of 1986, as amended, non-U.S. persons are subject to U.S. federal income tax in the same manner as U.S. persons on any gain realized on the disposition of an interest, other than an interest solely as a creditor, in U.S. real property. An interest in U.S. real property includes stock in a U.S. corporation (except for certain stock of publicly traded U.S. corporations) if, with respect to a non-U.S. holder, interests in U.S. real property constituted 50% or more by value of the sum of the corporation’s assets used in a trade or business, its U.S. real property interests and its interests in real property located outside the United States at any point in time during the shorter of the period during which such non-U.S. holder held such stock or the 5-year period ending on the date of the disposition of such interest (a "USRPHC").
It is unclear if the Company's subsidiary holding our operations in Hawaii will be treated as a USRPHC for U.S. federal income tax purposes as of the date of the Merger. If such subsidiary were treated as a USRPHC as of such date, the Merger could have certain negative tax consequences for non-U.S. holders of common units, including causing such non-U.S. holders to be subject to U.S. federal income tax and related withholding under the FIRPTA provisions of the Code on any gain realized by such holder on the Merger.
If you are a non-U.S. holder, you are urged to consult your own tax advisors with regard to the U.S. federal income tax consequences to you (as well as the effects of state, local and non-U.S. tax laws) resulting from participation in the Merger.
COVID-19 could have a material adverse effect on our results of operations, financial condition, liquidity, capital expenditures, and the trading value of our securities.
COVID-19 has negatively affected the global economy, disrupted financial markets, disrupted supply chains, significantly reduced travel, and interrupted business activity. Federal, state, and local governments have implemented mitigation measures including travel restrictions, stay-at-home orders, border closings, restrictions on public gatherings, social distancing, shelter-in-place restrictions, and various limitations on business operations. Although our business is considered an essential service, these government actions have adversely affected the ability of our employees, customers, suppliers, and other business partners to conduct business activities, and could do so for an extended period of time. This could have a material adverse impact on our results of operations, financial condition, liquidity, capital expenditures, and the trading value of our securities. Risks include:
Impact on demand for our services and supply chain disruption. Tourism in Hawaii has declined, resulting in the full or partial closure of hotels and restaurants, which has reduced the consumption of gas. We cannot predict whether the pandemic will permanently change our customers' behavior or whether such changes could materially impact our businesses. Hawaii Gas’ SNG plant is subject to minimum operating thresholds, and if demand declines such that the SNG plant is not producing the requisite daily volume of SNG to operate safely, the plant will be shut down until minimum production thresholds can again be met. While Hawaii Gas has developed and tested alternatives for the delivery of gas to its utility customers in the event production at the SNG plant is stopped, there can be no assurances that these alternatives would operate as designed or be as effective and efficient from an operating or financial performance perspective as operating the SNG plant. Additionally, the reliability and pricing of the feedstock supply for the SNG plant could be adversely impacted by COVID-19, potentially resulting in higher cost of gas which would be passed through to customers. In addition, disruptions in the supply chain driven by the pandemic could result in a delay or an inability to obtain products, supplies, and services needed in our operations.
Impact on employees and on cybersecurity. Many of our personnel are working remotely, and many employees at our facilities are abiding by social distancing procedures. In addition, our operations may be negatively affected by employee illness and/or quarantines. Further, our management teams have been required to devote large amounts of time and resources to mitigate the impact of the pandemic, thereby diverting attention from other priorities. In addition, the large scale remote working environment increases the risks posed by information technology systems breaches.
Impact on liquidity and financial metrics. The ongoing effect of the pandemic on our business could affect our liquidity position, our cost of and ability to access funds from financial institutions and the capital markets and could cause a deterioration in our financial metrics or the business environment that could make it more difficult to meet the financial covenants in our credit facilities.
Impact on capital expenditures and costs. We have deferred and may defer certain non-essential capital expenditures, including certain growth capital expenditures. If we are unable to deploy growth capital as planned, our long-term development prospects and ability to meet competitive challenges could be compromised. We are also incurring additional costs associated with the Company’s pandemic response measures.

Impact on our customers' ability to pay. The pandemic's impact on the financial condition and operating results of our customers may result in delayed payments and uncollectible accounts receivable, and could also result in the bankruptcy, insolvency, or cessation of the business of certain of our customers.
Impact on trading and asset value. COVID-19 has resulted in volatile equity markets and meaningfully lower stock prices for many companies, including ours, and may do so in the future.
The effects of COVID-19 may continue for an extended period, and the ultimate impact of the pandemic will depend on future developments which are highly uncertain and cannot be predicted including, without limitation, the duration and severity of the pandemic, the duration of governmental mitigation measures, the effectiveness of the actions taken to contain and treat the disease, and the length of time it takes for normal economic and operating conditions to resume. The situation surrounding COVID-19 remains fluid and the potential for material effects on our operating results, financial condition, and liquidity increases the longer the pandemic impacts activity levels in the U.S. and globally.
Fluctuations in economic, equity, and credit market conditions may have a material adverse effect on our results of operations, our liquidity, or our ability to obtain credit on acceptable terms.
Should economic, equity, and credit market conditions, collectively or individually, become disrupted, our ability to raise equity or obtain capital, to repay or refinance credit facilities at maturity, make significant capital expenditures, to pay, maintain or increase a dividend or fund growth may be costly and/or impaired. Our access to debt financing in particular will depend on a variety of factors such as market conditions, the general availability of credit, the overall availability of credit to our industry, our credit history and credit capacity, as well as the historical performance of our business and lender perceptions of financial prospects. If we are unable to obtain debt financing, particularly as significant credit facilities mature, our internal sources of liquidity may not be sufficient.
Economic conditions may also increase our counterparty risk, and should conditions deteriorate, we would expect to see increases in counterparty defaults and/or bankruptcies, which could result in an increase in bad debt expense and may cause our operating results to decline.
Volatility in the financial markets may make projections regarding future obligations under pension plans difficult. We maintain defined benefit retirement plans. Future funding obligations under those plans depend in large part on the future performance of plan assets and the mix of investment. These defined benefit plans hold a significant amount of equity and fixed income securities. If the market values of these securities decline or if returns decline, our pension expense and cash funding requirements would increase and, as a result, could materially adversely affect the results and liquidity of the business and our Company.
A tight labor market could increase the cost of operating or make it more difficult to recruit and retain those with appropriate skillsets. In a tight labor market, it may take longer to identify and hire additional employees and such delays could, in turn, increase fees paid to recruiting firms or the amount of overtime paid to existing employees. A tight labor market may also drive the cost of retaining employees with appropriate skillsets higher to the extent we face increased competition from employers willing or able to pay higher wages.
The documents governing our debt impose significant operating and financial restrictions, which may prevent us from pursuing certain business opportunities and taking certain actions.
Our debt agreements may impose operational and financial restrictions on us. These restrictions could limit or prohibit, among other things, our ability to:
incur additional indebtedness;
cause operating companies to make distributions to the holding company, redeem subordinated debt or make other restricted payments;
make certain investments or acquisitions;
grant or permit certain liens on our assets;
enter into certain transactions with affiliates;
merge, consolidate, or transfer substantially all of our assets; and
transfer or sell assets, including capital stock of our subsidiaries.
These covenants could adversely affect our ability to finance our future operations or capital needs, withstand a future downturn in our business or the economy in general, engage in business activities, including future opportunities that may be in our interest, and plan for or react to market conditions or otherwise execute our business strategies. If a default occurs, the relevant lenders or holders of such indebtedness could elect to declare the indebtedness, together with accrued interest and other
11

TABLE OF CONTENTS
fees, to be immediately due and payable and proceed against any collateral securing that indebtedness. There is no guarantee that we would be able to satisfy our obligations if any of our indebtedness is accelerated.
If borrowing costs increase or if debt terms become more restrictive, the cost of refinancing and servicing our debt will increase, reducing our profitability, and ability to freely deploy capital. We and any of our existing or future subsidiaries may incur substantially more indebtedness. This could further exacerbate the risks to our business as described herein.
Most of our indebtedness matures within two years. Refinancing this debt may result in substantially higher interest rates or credit margins or substantially more restrictive covenants. Any of these could limit our operational and financial flexibility, limit or reduce our ability to pay dividends, and/or reduce distributions to our holding company. We cannot provide assurance that we will be willing or able to repay the debt if required.
If we are unsuccessful in concluding the pending Merger, or an alternate transaction, and continue to invest in and grow our business, we may incur substantial additional indebtedness. If new debt is added to our or any of our subsidiaries’ current debt levels, the related risks that we now face could be exacerbated.
The interest rates under our credit facilities may be adjusted for the phase-out of LIBOR.
LIBOR, the London Interbank Offered Rate, is the basic rate of interest used in lending between banks on the London interbank market and is widely used as a reference for setting the interest rates on loans globally. We generally use LIBOR as a reference rate to calculate interest rates under our credit facilities. In 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase out LIBOR, and in early 2021 announced USD LIBOR will be phased out by June 30, 2023. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, is considering replacing U.S. dollar LIBOR with a new index, the Secured Overnight Financing Rate ("SOFR"), calculated using short-term repurchase agreements backed by Treasury securities. SOFR may be more volatile than LIBOR. If LIBOR ceases to exist, we may need to renegotiate our credit agreements to replace LIBOR, and the interest rates under certain of our credit agreements may change. The new rates may not be as favorable to us as those currently in effect. We may also find it desirable to engage in more frequent interest rate hedging transactions.
Risks Related to Our Business Operations
The operations of our business are subject to a variety of competitive pressures and the actions of competitors could have a material adverse effect on operating results.
Energy resources including diesel, solar, geo-thermal, and wind, may be substituted for gas in certain end-use applications, particularly if the price of gas increases relative to these resources, whether due to higher costs or otherwise. Customers could elect to meet their energy needs through any or all of these alternate resources as a result of higher gas prices, lower costs of alternative generation resources, or convenience. This could have an adverse effect on our results of operations, cash flows, and financial condition.
Our business relies on its SNG plant, including its transmission pipeline, for a significant portion of its sales. Disruptions at that facility could adversely affect our ability to serve customers.
Disruptions at the SNG plant resulting from mechanical or operational issues or power failures could affect our ability to produce SNG. Most of the utility sales on Oahu are of SNG and all SNG is produced at the Oahu plant. We have a back-up system in place, however, disruptions to both the primary and the back-up systems could have a significant adverse effect on our results of operations, cash flows, and financial condition.
Our business obtains its feedstock for its SNG plant from a refinery located on Oahu and sources its LPG supply from an off-island distributor. Supply disruptions may have an adverse effect on the operations of the business.
The extended unavailability of the refinery that supplies SNG feedstock, or the inability to purchase LPG from off-island sources, could adversely affect operations. Our business has a limited ability to store LPG, and any disruption in supply may cause a depletion of LPG stocks. Disruptions in the supply of SNG or LPG, if occurring for an extended period, could materially adversely impact the business’ results of operations, cash flows, and financial condition.
Our business is subject to risks associated with volatility in the Hawaii economy.
Hawaii’s economy and demand for our business’ products are heavily influenced by economic conditions in the U.S. and Asia and their impact on tourism, including the impact of post COVID-19 demand for travel, as well as by government spending. If the decline in the tourism industry in Hawaii is sustained, or there are changes in travel behavior post COVID-19, or the local economy deteriorates, the amount of gas we sell could be negatively affected by business closures or reduced consumption, which could adversely impact the business’ financial performance. Additionally, slow, or no economic growth in Hawaii could adversely impact the amount of gas we sell to new and existing customers and reduce the level of new
12

TABLE OF CONTENTS
commercial and residential construction. A reduction in visitors to Hawaii or government activity in Hawaii, particularly military activity could also have a negative impact on our business.
Reductions in U.S. military spending could result in a reduction in demand for gas in Hawaii.
The U.S. military has a significant presence in Hawaii and is a substantial contributor to its economy. To the extent that federal spending cuts, including voluntary or mandatory cuts in U.S. military spending result in a reduced military presence in Hawaii, such reductions could reduce the demand for gas and new construction in Hawaii.
Because of its geographic location, Hawaii, and in turn our business, are subject to earthquakes, volcanos, and certain weather risks that could materially disrupt operations.
Hawaii is subject to earthquakes, volcanic activity, and certain weather risks, such as hurricanes, floods, heavy and sustained rains, and tidal waves that could materially disrupt operations. Because our properties, such as our SNG plant, SNG transmission line and several storage facilities, are close to the ocean, weather-related disruptions to operations are possible. In addition, earthquakes and volcanic activity may cause disruptions. These events could damage our assets or could result in wide-spread damage to our customers, thereby reducing the amount of gas sold and, to the extent such damages are not covered by insurance, adversely impact our results of operations, cash flows, and financial condition.
Fluctuations in commodity prices could adversely impact revenue, cost of services/goods sold, and gross margin of our business.
Our revenue is generated primarily from the re-sale of a commodity. LPG, LNG, and feedstock for the SNG plant are commodities and changes in global supply of and demand for these products can have a significant impact on costs. We have no control over commodity prices and, to the extent that these prices cannot be hedged or passed on to customers, our results of operations, cash flows, and financial condition could be adversely affected.
Depending on the terms of our contracts with suppliers, as well as the extent and success of our use of financial instruments to reduce our exposure related to volatility in the cost of LPG, changes in the market price of fuel supplies could create payment obligations that expose our business to increased liquidity risk.
We enter into commodity hedge contracts to hedge against financial risks of commodity price fluctuations of LPG purchases. Depending on the terms of the commodity hedge contracts, as well as our ability to forecast sales volumes, changes in the expected volumes sold and changes in the market price of the commodity hedge contracts could create payment obligations that adversely effect our results of operations, cash flows, and financial conditions.
Our business experiences a measure of seasonality and such seasonality may cause fluctuations in our results of operations.
Our business may generate incrementally more cash during the peak tourism periods in Hawaii between mid-December and the end of March and from mid-June through mid-September. Annualization of peak period performance could result in an overly optimistic estimate of the value of our common units.
We seek to increase our use of renewable feedstocks and to increase the percentage of RNG distributed to our customers. This initiative exposes us to new technology, supply, counterparty, and regulatory risks that could impact the performance of our business.
We are pursuing a range of renewable resources that may provide pipeline quality gas in scalable quantities. These initiatives include the current contract for recovery of biogas from the Honouliuli wastewater treatment plant and ongoing discussions with operators of additional wastewater treatment plants and landfills, and with biomass producers. Blending of RNG with existing fuels and integrating RNG into the pipeline network may present technical challenges resulting in project delays, cost overruns or pipeline disruptions. Use of RNG may also expose us to the risk of supply fluctuations due to the variability in performance of processes such as anaerobic digestion. These technical and supply risks may impact the financial performance of our business.
Energy efficiency and technology advances, as well as conservation efforts and changes in the sources and types of energy produced in the U.S. may result in reduced demand for our products and services.
Conservation and technological advances including installation of improved insulation, the development of more efficient heating and cooling devices and advances in energy generation technology, may reduce demand for certain of our products and services. During periods of high energy commodity costs, the prices of certain of our products and services generally increase, which may also lead to increased conservation. In addition, federal and/or state regulation may require mandatory conservation measures, which could also reduce demand.
The discovery and development of new and unconventional energy sources in the U.S. may drive changes in related energy product logistics chains. The location and exploitation of these new energy sources could result in the dislocation of certain portions of our business. Changes in energy supply chain logistics or trends toward increased conservation could reduce demand for our products and services and could adversely affect our results of operations, cash flows, and financial condition.

TABLE OF CONTENTS
Our business is subject to environmental risks that may impact our future profitability.
Our business is subject to numerous statutes, rules and regulations relating to environmental protection and are exposed to various environmental risk and hazards, including those associated with the refining, storage, and handling of combustible products.
Materialization of these risks could result in substantial losses including personal injury, loss of life, damage or destruction of property and equipment and environmental damage. Any losses we face could be greater than insurance levels and could have an adverse effect on our financial results. We also could be subject to fines and penalties for violation of applicable environmental regulations, which could be substantial. In addition, disruptions to physical assets could reduce our ability to serve customers and adversely affect future sales and cash flows.
Failure to comply with regulations or other claims may interrupt operations and result in civil or criminal penalties, significant unexpected compliance costs and liabilities that could adversely affect the profitability of our business. These rules and regulations are subject to change and compliance with any changes could result in a restriction of the activities, significant capital expenditures, and/or increased ongoing operating costs.
We own or lease properties that have been subject to environmental contamination in the past and could require remediation for which we are or may be liable. The remediation could cost more than anticipated or could be incurred earlier than anticipated, or both. In addition, the business may discover additional environmental contamination that may require remediation at significant cost. Further, the past contamination of the properties, including by former owners or operators of such properties, could result in remediation obligations, personal injury, property damage, environmental damage, or similar claims by third parties.
We may also be required to address other prior or future environmental contamination, including soil and groundwater contamination that results from the spillage of fuel, hazardous materials, or other pollutants. Under various federal, state, and local environmental statutes, rules and regulations, a current or previous owner or operator of real property may be liable for noncompliance with applicable environmental and health and safety requirements and for the costs of investigation, monitoring, removal or remediation of hazardous materials. These laws often impose liability, whether the current owner or operator knew of, or was responsible for, the presence of hazardous materials. Persons who arrange for the disposal or treatment of hazardous materials may also be liable for the costs of removal or remediation of those materials at the disposal or treatment facility, whether or not that facility is or ever was owned or operated by that person and whether or not the original disposal or treatment activity accorded with all regulatory requirements. The presence of hazardous materials on a property could result in personal injury, loss of life, damage or destruction of property and equipment, environmental damage and/or claims by third parties that could have a material adverse effect on our results of operations, cash flows, and financial condition.
Unfavorable publicity or public perception of the industry in which we operate could adversely impact our operating results and our reputation.
Negative publicity, public, or investor perception of the energy-related industry in which we operate, including through media coverage of environmental contamination and climate change concerns, could reduce demand for our services and harm our reputation. Any reduction in demand for the services we provide or damage to our reputation could have a material adverse effect on our unit price, results of operations, cash flows, financial condition, and business prospects.
We are dependent on certain key personnel, and the loss of key personnel, or the inability to retain or replace qualified employees, could have an adverse effect on our business, results of operations, cash flows, and financial condition.
We rely on an existing management team for day-to-day operations. Consequently, our operational success, as well as the completion of our pending Merger, will depend on the continued efforts of the management team, who have extensive experience in the day-to-day operations of our business. The loss of key personnel, or the inability to retain or replace qualified employees, could have an adverse effect on our business, results of operations, cash flows, and financial condition.
Because of its geographic location and the unique economy of Hawaii, our business is subject to challenges in hiring and maintaining staff with specialized skill sets.
The changing nature of the Hawaii energy complex has had an impact on the business' staffing requirements. Volatility in feedstock prices, together with the impact of the State of Hawaii’s goals to reduce dependency on imported petroleum, requires staff with specialized knowledge of the energy sector. Because the resident labor pool in Hawaii is both small and oriented mainly to Hawaii’s basic industries, it is difficult to find individuals with these specialized skill sets. Unemployment rates in Hawaii are traditionally lower than those in the U.S. Mainland. Moreover, relocation to Hawaii is costly and often requires employees to make cultural and family adjustments not normally required in a relocation. The inability to source and retain staff with appropriate skill sets could adversely impact the performance of our business. In addition, dependence on skilled labor trades could result in constraints on growth and profitability related to competition for a limited labor pool.

TABLE OF CONTENTS
Prolonged work stoppages by employees who are subject to a collective bargaining agreement could adversely affect our financial position.
As of December 31, 2021, approximately 61% of our employees were covered by collective bargaining agreements. Although we believe our employee relations to be generally good, a prolonged work stoppage, strike or other slowdown at any facility with organized labor could significantly disrupt our operations and could have a material adverse effect on our business, results of operations, cash flows, or financial condition. In addition, we cannot ensure that upon the expiration of existing collective bargaining agreements, new agreements will be reached without union action or that any such new agreements will be on terms satisfactory to us. Any renegotiation of labor agreements could significantly increase our costs for wages, healthcare, and other benefits.
Our operations on the islands of Hawaii, Maui and Kauai rely on LPG that is transported from Oahu to those islands by Jones Act qualified barges and by non-Jones Act vessels from off-island ports. Disruptions to service by those vessels could adversely affect the financial performance of our business.
The Jones Act requires that all goods transported by water between U.S. ports be carried in U.S.-flag ships and that they meet certain other requirements. We have time charter agreements for the only two Jones Act qualified barges available in Hawaii capable of carrying large amounts of LPG. If the barges are unable to transport LPG from Oahu and the business is not able to secure off-island sources of LPG or obtain an exemption to the Jones Act that would permit importation of a sufficient quantity of LPG from the U.S. mainland, we could be adversely affected. If the barges require refurbishment or repair at a greater frequency than forecast, cash outflows for capital costs could adversely impact our results of operations, cash flows, and financial condition.
Generation underperformance at individual projects within our business could lead to financial penalties or contract terminations under existing off-take agreements.
Certain distributed generation projects have minimum production terms included in their respective power purchase agreements. These minimum production levels are specified in each respective contract. Failure to meet these minimum production levels, could result in liquidated damages, other financial penalties, or contract termination which could negatively impact our results of operations, cash flows, and financial condition.
Certain projects depend on electric interconnection and transmission facilities that we do not own or control and that are potentially subject to transmission constraints. If these facilities fail to provide adequate transmission capacity, the projects may be restricted in their ability to deliver electricity to customers.
Our electricity generation facilities depend on grid interconnection and transmission facilities owned and operated by others to deliver the power they produce. Certain off-taker contracts include limited provisions allowing for occasional curtailment of electricity generation due to the limitations of the electricity transmission system. Any constraints on, or the failure of, interconnections or transmission facilities could prevent us from selling power and could adversely affect our results of operations, cash flows, and financial condition.
Our business depends on counterparties, including operation and maintenance ("O&M") providers and power purchasers, performing in accordance with their agreements. If they fail to so perform, our business could incur losses of revenue or additional expenses and business disruptions.
Counterparties to long-term agreements with our business may not meet their obligations in accordance with such agreements. Should they fail to perform for any reason, we may be required to seek replacement service providers and customers. The failure of any of the parties to perform in accordance with these agreements could adversely affect our results of operations, cash flows, and financial condition.
Development and investment in our business involves various construction, operational, and regulatory risks that could materially adversely affect our financial results.
The development, construction, operation, and maintenance of our business involve various risks including, mechanical and structural failure, accidents, labor issues, or the failure of technology to perform as anticipated. Events outside our control, such as economic developments, changes in the prices of inputs, or governmental policy changes, could materially reduce the revenues generated or increase the expenses of constructing, operating or maintaining our business. Degradation of the performance of our infrastructure installations may reduce our revenues. Unanticipated capital expenditures associated with maintaining, upgrading, or repairing our infrastructure installations may reduce our profitability. We may also choose or be required to decommission a project or other asset. The decommissioning process could be protracted and result in significant financial and/or regulatory obligations or other uncertainties.
Our business may also face construction risks, including, without limitation:
labor disputes, work stoppages, or shortages of skilled labor;
15

TABLE OF CONTENTS
shortages of fuels or materials;
slower than projected construction progress and the unavailability or late delivery of necessary equipment;
delays caused by or in obtaining the necessary regulatory approvals or permits;
adverse weather conditions and unexpected construction conditions;
accidents or the breakdown or failure of construction equipment or processes;
difficulties in obtaining suitable or adequate financing; and
catastrophic or force majeure events such as explosions, fires and terrorist activities, and other similar events beyond our control.
Such developments could result in substantial unanticipated delays or expenses and, under certain circumstances, could prevent completion of construction activities once undertaken. Construction costs may exceed estimates for various reasons, including inaccurate engineering and planning, higher than anticipated labor and building material costs, and unanticipated problems with project start-up. Such unexpected increases may result in increased debt service costs and/or funds being insufficient to complete construction. New infrastructure installations under development may generate little or no cash flow through the date of completion of development and may experience operating deficits after the date of completion. In addition, market conditions may change during construction and make such development less attractive than at the time it was commenced. Any events of this nature could severely delay or prevent the completion of, or significantly increase the cost of, the construction. In addition, there are risks inherent in the construction work which may give rise to claims or demands against us from time to time. Delays in the completion of any project may result in lost revenues or increased expenses.
Warranties provided by our suppliers and contractors may be limited or insufficient to compensate our losses or may not cover the nature of our losses incurred.
We expect to benefit from various warranties, including product quality and performance warranties, provided by our suppliers and contractors. These suppliers and contractors, however, may file for bankruptcy, cease operations, or otherwise become unable or unwilling to fulfill their warranty obligations. Even if a supplier fulfills its warranty obligations, the warranty may not be enough to compensate us for our losses. In addition, the warranty period generally expires several years after the date that the equipment is delivered or commissioned and is subject to liability limits. Where damages are caused by defective products provided by our suppliers or construction services delivered by our contractors, our suppliers or contractors may be unable or unwilling to perform their warranty obligations as a result of their financial condition or otherwise, or if the warranty period has expired or a liability limit has been reached, there may be a reduction or loss of warranty protection for the affected projects, which could have a material adverse effect on our business’ results of operations, cash flows, and financial condition.
Security breaches or interruptions in our information technology systems, the loss or misappropriation of confidential information, or cyber-attacks on our facilities or those of third parties on which we rely, could materially adversely affect our business.
We rely on information technology networks and systems to process, transmit, and store electronic information used to operate our business, make operational decisions, and manage inventory. The information technology we use, as well as the information technology systems used by our Manager and third-party providers, could be vulnerable to security breach, damage or interruption from computer viruses, cyber-attacks, cyber terrorism, natural disasters, or telecommunications failures. If our technology systems, or those of our Manager or third-party providers, were to fail or be breached and we were unable to restore them in a timely manner, we may be unable to maintain critical business functions and/or confidential data could be compromised, we may incur substantial repair or replacement costs and/or our reputation could be damaged. The occurrence of any of these could have a material adverse effect on our business, results of operations, cash flows, and financial condition.
We transmit confidential credit card information by way of secure private retail networks and rely on encryption and authentication technology licensed from third parties to provide the security and authentication necessary to effect secure transmission and storage of confidential information, such as customer credit card information. Any material failure by us to achieve or maintain compliance with the Payment Card Industry security requirements or to rectify a security issue may result in fines and the imposition of restrictions on our ability to accept credit cards as a form of payment. Any loss, disclosure or misappropriation of, or access to, customers’, employees’ or business partners’ information or other breach of our information security can result in legal claims or legal proceedings, including regulatory investigations and actions, may have a negative impact on our reputation, could result in loss of customers, could lead to regulatory enforcement actions against us, and could materially adversely affect our business, results of operations, cash flows, and financial condition.
If our information technology systems, or the information technology systems of third parties on which we rely, cease to function properly or our cybersecurity is breached, we could suffer disruptions to our normal operations including: (i) unauthorized access to our facilities or a cyber-attack on our automated systems, or the power grids or communications
16

TABLE OF CONTENTS
networks we use, that could cause operational disruption and potential environmental hazards; (ii) a cyber-attack on third-party transportation systems that could result in supply chain disruptions, or prevent our business from transporting product to our customers; and (iii) a cyber-attack on power generation facilities or refineries that could significantly impact prices and demand in the commodities markets. Any of these events could materially adversely affect our operating results. Additionally, certain cyber incidents may remain undetected for an extended period. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities.
Regulatory and Governmental Risks
Our utility operations are subject to regulation by the HPUC and actions by the HPUC or changes to the regulatory environment may constrain the operation or profitability of the business.
The HPUC regulates all public service companies operating in Hawaii. The HPUC prescribes rates, tariffs, charges and fees; determines the allowable rate of return on equity; issues guidelines concerning the general management of utility businesses and acts on requests for the acquisition, sale, disposition or other exchange of utility properties, including mergers and consolidations.
Any adverse decision by the HPUC concerning the level or method of determining utility rates, the items and amounts that may be included in the rate base, the returns on equity or rate base, the potential consequences of exceeding or not meeting such returns, or any prolonged delay in rendering a decision in a rate or other proceeding, could have an adverse effect on our business.
On November 25, 2020, the HPUC initiated further proceedings consistent with the Hawaii Supreme Court’s order remanding the rate case for consideration, among other things, of greenhouse gas emission occurring outside the state's borders. We cannot predict the timing or outcome of this proceeding, or the effects of that outcome on our business.
Natural gas has increasingly been the subject of political and public scrutiny, including a desire by some to further limit or eliminate reliance on natural gas as an energy source. The enactment of state legislation in 2018 requiring Hawaii to be carbon neutral by 2045 or a potential Renewable Portfolio Standard ("RPS") for utility gas usage or supply, similar to the one implemented for electric utility generation, could result in supply disruptions, increased energy costs to ratepayers or a negative impact on the future financial performance of our business.
The Hawaii legislature or municipal governments could impose a gas RPS, enact other restrictive legislation or impose changes to building codes, which may result in increased energy costs to the business and its customers (i.e. the cost of finding new renewable fuel supplies or developing new technologies could be prohibitive), in supply disruptions and/or in restriction of existing and future business. Similar impacts could result from the enactment of the carbon neutrality legislation in 2018.
Our income may be adversely affected if additional compliance costs are required as a result of new safety, health, and/or environmental regulation.
Our business is subject to federal, state, and local safety, health, and environmental laws and regulations. These laws and regulations affect many aspects of their operations and are modified frequently. There is a risk that our business may not be able to comply with some aspect of these laws and regulations, resulting in fines or penalties. Additionally, if new laws and regulations are adopted or if interpretations of existing laws and regulations change, we could be required to increase capital spending and/or incur increased operating expenses to comply. Because the regulatory environment changes frequently, we cannot predict when or how we may be affected by such changes. Emissions and other compliance testing technologies continue to improve, which may result in more stringent, targeted environmental regulations, and compliance obligations in the future, the costs of which could be material and adversely affect our results of operations, cash flows, and financial condition.
Our business is dependent on our contractual and regulatory relationships with government entities that may have significant leverage over us. Government entities may be influenced by political considerations to take actions adverse to us.
Our business generally is, and will continue to be, subject to substantial regulation by governmental agencies. In addition, our business relies on obtaining and maintaining government permits, licenses, concessions, leases, or contracts. Government entities, due to the wide-ranging scope of their authority, have significant leverage over us in their contractual and regulatory relationships with us that they may exercise in a manner that causes delays in the operation of our business or pursuit of our strategy, or increased administrative expense. Furthermore, government operating requirements, permits, licenses, concessions, leases, and contracts are generally very complex, and may result in periods of non-compliance, or disputes over interpretation or enforceability. If we fail to comply with these regulations or contractual obligations, we could be subject to financial penalties or we may lose our rights to operate the affected business, or both. Where our ability to operate is subject to a concession or lease from government entities, the concession or lease may restrict our ability to operate in a way that maximizes cash flows and profitability. Further, our ability to grow may require consent of numerous government regulators. Increased regulation restricting the ownership or management of U.S. assets by non-U.S. persons, given the non-U.S. ultimate ownership
17

TABLE OF CONTENTS
of our Manager, may limit our ability to pursue acquisitions. Any such regulation may also limit our Manager’s ability to continue to manage our operations, which could cause disruption to our business and a decline in our performance. In addition, any required government consents may be costly to seek and we may not be able to obtain them. Failure to obtain any required consents could limit our ability to grow.
Our contracts with government entities may also contain clauses more favorable to the government counterparty than a typical commercial contract. For instance, a lease, concession, or general service contract may enable the government to terminate the agreement without adequate compensation. In addition, government counterparties also may have the discretion to change or increase regulation of our operations, or implement laws or regulations affecting our operations, separate from any contractual rights they may have. Governments have considerable discretion in implementing regulations that could impact these businesses. Governments may be influenced by political considerations to take actions that may hinder the efficient and profitable operation of our business.
Many of our contracts, especially those with government entities or quasi-governmental entities are long-term contracts. These long-term contracts may be difficult to replace if terminated. In addition, buy-out or other early termination provisions could adversely affect our results of operations, cash flows, and financial condition if exercised before the end of the contract.
Government agencies may determine the prices we charge and may be able to restrict our ability to operate our businesses to maximize profitability.
We are subject to rate regulation in respect of our regulated utility in Hawaii. We may also face fees or other charges over which we have no control that increase our costs. We may be subject to increases in fees or unfavorable price determinations that may be final with no right of appeal or that, despite a right of appeal, could result in our profits being negatively affected. In addition, we may have very little negotiating leverage in establishing contracts with government entities, which may decrease the prices that we otherwise might be able to charge or the terms upon which we provide products or services. Businesses we may acquire in the future may also be subject to rate regulation or similar negotiating limitations.
Failure to comply with government regulations could result in loss of franchise contract terminations or we may be unable to enter into future government contracts.
Our regulated utility business is the only gas distribution franchise in Hawaii and is subject to significant regulation. The HPUC prescribes rates, tariffs, charges and fees; determines the allowable rate of return on equity; issues guidelines concerning the general management of utility businesses and acts on requests for the acquisition, sale, disposition or other exchange of utility properties, including mergers and consolidations. If we fail to comply with any of these regulations, requirements, or statutes we could lose the franchise.
From time to time, we sign government contracts that are subject to various uncertainties, restrictions, and regulations which could result in withholding or delay of payments. In addition, government contracts are subject to specific regulations as well as various statutes related to employment practices, environmental protection, recordkeeping, and accounting. These regulations and laws impact how we transact business with governmental clients and, in some instances, impose significant costs on business operations. If we fail to comply with any of these regulations, requirements or statutes, our existing government contracts could be terminated, and we could be temporarily or permanently barred from government contracting or subcontracting. If one or more of our government contracts are terminated or if we are barred from government contract work, or if reimbursement of our cost is disallowed, we could suffer a significant reduction in expected revenue and profits.
Delays in the government budget process or a government shutdown may adversely affect our operating results.
We provide services to government customers, often under long-term contracts. Any delay in the federal or state government budget process or a federal or state government shutdown may result in our incurring substantial costs without reimbursement under service contracts that we may have with government customers for extended periods. In addition, our business relies on obtaining and maintaining government permits, licenses, concessions, and leases. Governmental budget delays or government shutdowns could also negatively impact our ability to timely obtain approvals and consents needed to operate and grow our business. Any of these consequences could have an adverse impact on our operating results.
Climate change, climate change regulations, and greenhouse effects may adversely impact our operations and markets.
Climate change and the outcome of federal and state actions to address global climate change could result in significant new regulations, additional changes to fund energy efficiency activities, or other regulatory actions. These actions could increase the cost of operating our business, reduce the demand for our products and services, and impact the prices we charge our customers, any or all of which could adversely affect our results of operations. In addition, climate change could make severe weather events more frequent and increase the likelihood of capital expenditures to replace damaged physical property at our business.

Restrictions on emissions of methane or carbon dioxide that may be imposed could adversely impact the demand for, price of, and value of our products. As our operations also emit greenhouse gases directly, current and future laws or regulations limiting such emissions could increase our own costs. Future laws or regulations addressing greenhouse gas emissions could adversely impact our business.
Risks Related to Having an External Manager
We are subject to the terms and conditions of the Management Services Agreement and Disposition Agreement between us and our Manager, which limit our ability to take certain actions and may make strategic transactions more costly.
We cannot unilaterally amend the Management Services Agreement between us and our Manager. Changes in the compensation of our Manager, certain rights held by our Manager or other components of the Management Services Agreement require the approval of our Manager and limit our ability to make changes that could be beneficial to equity holders generally without the consent of our Manager.
On October 30, 2019, we signed a Disposition Agreement with our Manager to facilitate our pursuit of strategic alternatives (see Exhibit 10.3 of this Form 10-K). Outside of this agreement, we do not have the ability to terminate the Management Services Agreement other than in limited circumstances. The Disposition Agreement will terminate on the earlier to occur of (i) the termination of the Management Services Agreement and (ii) the sixth anniversary of the Disposition Agreement, subject to extension under certain circumstances if a transaction is pending.
Our Manager owns a significant portion of our outstanding common units. A sale of all or a portion of the common units owned by our Manager could be interpreted by the equity markets as a lack of confidence in our prospects.
Our Manager, in its sole discretion, determines whether to reinvest base management and performance fees, if any, in common units and whether to hold or sell those securities. Reinvestment of base management and performance fees, if any, in additional common units would increase our Manager’s ownership stake in our Company. On December 31, 2021, our Manager owned 16.66% of our outstanding common units. Our Manager has sold and could from time to time sell the common units that it acquires via reinvestment of fees. If our Manager decides to sell any of its common units in our Company, such sales may be interpreted by some market participants as a lack of confidence in our Company and put downward pressure on the market price of our common units. Sales of common units by our Manager would increase the supply and could decrease the price if demand is insufficient to absorb such sales.
Outside of the construct created by our pursuit of strategic alternatives, and the execution of the Disposition Agreement, certain provisions of our Management Services Agreement, articles of organization, and operating agreement would otherwise make it difficult for third parties to acquire control of our Company and could deprive investors of the opportunity to obtain a takeover premium for their shares of common units.
Subject to terms of the Disposition Agreement, there are limited circumstances in which our Manager can be terminated under our Management Services Agreement. The Management Services Agreement provides that in circumstances where our common units ceases to be listed on a recognized U.S. exchange as a result of the acquisition of our common units by third parties in an amount that results in our common units ceasing to meet the distribution and trading criteria on such exchange or market, our Manager has the option to either propose an alternate fee structure and remain as our Manager or resign, terminate the Management Services Agreement upon 30 days’ written notice and be paid a substantial termination fee. The termination fee payable on our Manager’s exercise of its right to resign as our Manager subsequent to a delisting of our common units could delay or prevent a change in control that may favor our equity holders. Furthermore, in the event of such a delisting, any proceeds from the sale, lease, or exchange of a significant amount of assets must be reinvested in new assets of our Company, subject to debt repayment obligations. We would also be prohibited from incurring any new indebtedness or engaging in any transactions with equity holders or our affiliates without the prior written approval of our Manager. These provisions could deprive equity holders of opportunities to realize a premium on the common units owned by them. The Disposition Agreement provides that the Management Services Agreement will terminate as to any businesses, or substantial portions thereof, that are sold, and certain payments will be made to our Manager in connection therewith.
Our operating agreement contains provisions that could have the effect of making it more difficult for a third-party to acquire, or discouraging a third-party from acquiring, control of our Company. These provisions include:
restrictions on our ability to enter into certain transactions with our major equity holders, with the exception of our Manager;
allowing only our Board to fill vacancies, including newly created directorships, and requiring that directors may be removed with or without cause by a common unit holder vote of 66 2/3%;
requiring that only the chairman or Board may call a special meeting of our common unit holders;
prohibiting common unit holders from taking any action by written consent;
19

TABLE OF CONTENTS
establishing advance notice requirements for nominations of candidates for election to our Board or for proposing matters that can be acted upon by our equity holders at an common unit holders’ meeting; and
having a substantial number of additional common units authorized but unissued.
Our Manager’s decision to reinvest its monthly base management fees and quarterly performance fees, if any, in common units or retain the cash will affect equity holders differently.
Our Manager is paid a base management fee based on our market capitalization and potentially performance fees based on the total return generated relative to a U.S. utilities index benchmark. Our Manager, in its sole discretion, may elect to retain base management fees and performance fees, if any, paid in cash or to reinvest such payments in additional common units. In the event our Manager chooses not to reinvest the fees to which it is entitled in additional common units, the amount paid will reduce the cash that may otherwise be distributed as a dividend to all equity holders or used in our Company’s operations. In the event our Manager chooses to reinvest the fees to which it is entitled in additional common units, effectively returning the cash to us, such reinvestment and the issuance of new common units will dilute existing equity holders by the increase in the percentage of common units owned by our Manager. Either option may adversely impact the market for our common units.
In addition, our Manager has typically elected to invest its fees in common units, and, unless otherwise agreed with us, can only change this election during a 20-trading day window following our earnings release. Any change would apply to fees incurred thereafter. Accordingly, equity holders would generally have notice of our Manager’s intent to receive fees in cash rather than reinvest before the change was effective.
Our Manager is not required to offer all acquisition opportunities to us and may offer such opportunities to other entities. Our management may waive investment opportunities presented by our Manager.
Pursuant to our Management Services Agreement, we have first priority ahead of all current and future funds, investment vehicles, separate accounts, and other entities managed by our Manager or by members of the Macquarie Group with respect to four specific types of acquisition opportunities within the United States. These include FBOs, airport parking, district energy, and “user pays”, contracted, and regulated assets that represent an investment of greater than AUD $40 million. Other than these types of opportunities, our Manager does not have an obligation to offer to us any particular acquisition opportunities, even if they meet our investment objectives, and our Manager and its affiliates can offer any or all other acquisition opportunities on a priority basis or otherwise to current and future funds, investment vehicles, and accounts sponsored by our Manager or its affiliates. We may compete with these entities for investment opportunities, and there can be no assurance that we will prevail with respect to such investments.
In addition, our management may determine not to pursue investment opportunities presented to us by our Manager, including those presented on a priority basis. If our management waives any such opportunity, our Manager and its affiliates may offer such opportunity to any other entity, including any entities sponsored or advised by members of the Macquarie Group. As such, not every acquisition opportunity presented to us by our Manager may be pursued by us and may ultimately be presented to entities with whom we compete for investments.
Our Manager can resign with 90 days’ notice, and our CEO or CFO could be removed by our Manager, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations, which could adversely affect our financial results and negatively impact the market price of our common units.
Our Manager has the right, under the Management Services Agreement, to resign at any time with 90 days’ notice, whether we have found a replacement manager or not. In addition, our Manager could re-assign or remove our CEO and/or our CFO from their positions and responsibilities at our Company without our Board's approval and with little or no notice. If our Manager resigns or our CEO and/or CFO are removed, we may not be able to find a new external manager or hire internal management with similar expertise within 90 days to provide the same or equivalent services on acceptable terms, or at all. If we are unable to do so, our operations are likely to experience a disruption, our financial results could be adversely affected, perhaps materially, and the market price of our common units may decline substantially. In addition, the coordination of our internal management, acquisition activities, and supervision of our businesses is likely to suffer if we were unable to identify and reach an agreement with a single institution or group of executives having the expertise possessed by our Manager and its affiliates.
Furthermore, if our Manager resigns, we and our subsidiaries will be required to cease use of the Macquarie brand and change their names to remove any reference to “Macquarie”. This may cause the value of our Company and the market price of our common units to decline.
Our externally managed model may not be viewed favorably by investors.
We are externally managed by a member of the Macquarie Group. Our Manager receives a fee for the corporate headquarters functions it provides including the compensation of our management team and those who provide services to us on
20

TABLE OF CONTENTS
a shared basis, health and welfare benefits, the provision of facilities, technology, and insurance (other than directors and officers). The fee is based on our equity market capitalization and thus increases as we grow. The size of the fee may bear no direct correlation with the actual cost of providing the agreed upon services and may be higher than the cost of managing our Company internally. Per the terms of the Management Services Agreement with our Manager, the current default election for satisfying any base management or performance fees, if any, to which our Manager may be entitled is the issuance of additional common units. To the extent fees continue to be reinvested in our common units, all equity holders will be diluted.
Our Manager’s affiliation with Macquarie Group Limited and the Macquarie Group may result in conflicts of interest or a decline in the market price of our common units.
Our Manager is an affiliate of Macquarie Group Limited and a member of the Macquarie Group. From time to time, we have entered into, and in the future, we may enter into, transactions and relationships involving Macquarie Group Limited, its affiliates, or other members of the Macquarie Group. Such transactions have included and may include, among other things, the entry into debt facilities and derivative instruments with members of the Macquarie Group serving as lender or counterparty, and financial advisory or equity and debt underwriting services provided to us by the Macquarie Group.
Although our Audit Committee, all of the members of which are independent directors, is required to review and approve in advance of any related party transactions, including those involving members of the Macquarie Group or its affiliates, the relationship of our Manager to the Macquarie Group may result in conflicts of interest.
In addition, as a result of our Manager’s being a member of the Macquarie Group, negative market perceptions of Macquarie Group Limited generally or of Macquarie’s infrastructure management model, or Macquarie Group statements or actions with respect to other managed vehicles, may affect market perceptions of us and cause a decline in the price of our common units unrelated to our financial performance and prospects.
In the event of the underperformance of our Manager, we may be unable to remove our Manager, which could limit our ability to improve our performance and could adversely affect the market price of our common units.
Under the terms of the Management Services Agreement, our Manager must significantly underperform for the Management Services Agreement to be terminated. Our Board cannot remove our Manager unless:
our common units underperforms a weighted average of two benchmark indices by more than 30% in relative terms and more than 2.5% in absolute terms in 16 out of 20 consecutive quarters prior to and including the most recent full quarter, and the holders of a minimum of 66.67% of our common units (excluding any common units owned by our Manager or any affiliate of our Manager) vote to remove our Manager;
our Manager materially breaches the terms of the Management Services Agreement and such breach has been unremedied within 60 days after notice;
our Manager acts with gross negligence, willful misconduct, bad faith or reckless disregard of its duties in carrying out its obligations under the Management Services Agreement, or engages in fraudulent or dishonest acts; or
our Manager experiences certain bankruptcy events.
Our Board cannot remove our Manager unless the market performance of our common units also significantly underperforms the benchmark index. If we were unable to remove our Manager in circumstances where the absolute market performance of our common units does not meet expectations, the market price of our common units could be negatively affected.
Risks Related to Ownership of Our Common Units
The market price and marketability of our common units may from time to time be significantly affected by numerous factors beyond our control, which may adversely affect our ability to raise capital through future equity financings.
The market price of our common units may fluctuate significantly. Many factors that are beyond our control may significantly affect the market price and marketability of our common units and may adversely affect our ability to raise capital through equity financings should we need or want to do so. These factors include, but are not limited to:
any developments impacting our ability to consummate the Merger;
significant volatility in the market price and trading volume of securities of Macquarie Group Limited and/or vehicles managed by the Macquarie Group or branded under the Macquarie name or logo;
significant volatility in the market price and trading volume of securities of registered investment companies, business development companies, or companies in our sector;
changes in our earnings or variations in operating results;
21

TABLE OF CONTENTS
publications by ratings agencies;
any shortfall in EBITDA excluding non-cash items or Free Cash Flow from levels expected by us or by securities analysts;
changes in regulatory policies or tax law;
operating performance of companies comparable to us;
loss of funding sources; and
substantial sales of our common units by our Manager or other significant equity holders.
Actions of activist equity holders could have an adverse impact on the value of our securities.
We value constructive input from our equity holders and the investment community. However, there is no assurance that the actions taken by our Board and management in seeking to maintain constructive engagement with our equity holders will be successful. Certain of our equity holders may express views with respect to the operation of our business, our business strategy, corporate governance considerations or other matters that are contrary to ours. Responding to these, or to actions that may be taken by activist equity holders can be costly and time-consuming, disruptive to our operations, and divert the attention of management and our employees. The perceived uncertainties as to our strategy as a result of the actions of activist equity holders could affect the market price of our securities, result in the loss of potential business opportunities, and make it more difficult to attract and retain qualified personnel, board members, and business partners.
The price of our common units may be vulnerable to actions of market participants whose strategies may not involve buying and holding our securities in pursuit of an attractive return.
Our common units have been the subject of short selling efforts by certain market participants. Short sales are transactions in which a market participant borrows, then sells a security that it does not own. The market participant is obligated to replace the security borrowed by purchasing the security at or before the time the security is recalled. If the price at the time of replacement/recall is lower than the price at which the security was originally sold by the market participant, then the market participant will realize a gain on the transaction. Thus, it is in the market participant’s interest for the price of the security to decline during the period up to the time of replacement/recall.
Previous short selling efforts have had an impact on, and may in the future impact, the value of our common units in an extreme and volatile manner to our detriment and the detriment of our equity holders. In addition, market participants have published, and may in the future publish, negative, inaccurate, or misleading information regarding our Company and our management team. We believe that the publication of such information has led, and may in the future lead to, significant downward pressure on the price of our common units to our detriment and the further detriment of our equity holders. These and other efforts by certain market participants to unduly influence the price of our common units for financial gain may cause value of our equity holders’ investments to decline, may make it more difficult for us to raise equity capital when or if needed without significantly diluting existing equity holders, and may reduce demand from new investors to purchase our common units.
We previously identified a material weakness in our internal control over financial reporting, and the failure to maintain an effective system of internal controls in the future could result in loss of investor confidence and adversely impact our common unit price.
Effective internal controls are necessary for us to provide reliable and accurate financial statements. If we are unable to maintain effective internal control over financial reporting or disclosure controls and procedures, our ability to record, process, and report financial information accurately, and to prepare financial statements within required time periods, could be adversely affected, which could cause investors to lose confidence in our reported financial information and have a negative effect on the price of our common units and our access to capital. In addition, implementing any appropriate changes to internal controls will result in additional expenses.
Our reported Income per Unit, as defined under GAAP, does not reflect the cash generated by our business and may result in unfavorable comparisons with other businesses.
We own and invest in high-value, long-lived assets that generate substantial amounts of depreciation and amortization. Depreciation and amortization are non-cash expenses that serve to reduce reported income per unit. We pay our Manager base management fees and may pay performance fees both of which may be reinvested in additional common units thereby rendering them a non-cash expense. Whether the fees are settled in cash or reinvested in additional common units, they have the effect of reducing income per unit. As a result, our financial performance may appear to be substantially worse compared with other businesses. To the extent that our results appear to be worse, we may have relatively greater difficulty attracting investors in our common units.
22

TABLE OF CONTENTS
Our total assets include a substantial amount of goodwill and other intangible assets. The write-off of a significant portion of intangible assets would negatively affect our reported earnings.
Our total assets reflect a substantial amount of goodwill and other intangible assets. On December 31, 2021, goodwill and other intangible assets, net, represented approximately 23% of our total assets. Goodwill and other intangible assets were generated primarily through the acquisition of Hawaii Gas. Other intangible assets consist of trade names. On at least an annual basis, we assess whether there has been any impairment in the value of goodwill and other intangible assets or when there are triggering events or circumstances. If the carrying value of the tested asset exceeds its estimated fair value, impairment is deemed to have occurred. In that event, the intangible is written down to fair value. Under current accounting rules, this would result in a charge to reported earnings. Impairments requiring the write-off of a significant portion of goodwill or other intangible assets would negatively affect our reported earnings and total capitalization and could be material. In addition, the ongoing impact of the pandemic on our business could cause an impairment to goodwill or long-lived assets of the Company.
Our total assets include a substantial amount of intangible assets and fixed assets. The depreciation and amortization of these assets may negatively impact our reported earnings.
The high level of intangible and physical assets written up to fair value upon acquisition generates substantial amounts of depreciation and amortization. These non-cash items serve to lower net income as reported in our consolidated statement of operations as well as our taxable income. The generation of net losses or relatively small net income may contribute to a net operating loss ("NOL") carryforward that can be used to offset current taxable income in future periods. However, the continued reporting of little or negative net income may adversely affect the attractiveness of our Company to some potential investors and may reduce the market for our common units.
Risks Related to Taxation
The current treatment of qualified dividend income and long-term capital gains under U.S. federal income tax law may be changed in the future.
Under current law, qualified dividend income and long-term capital gains are taxed to non-corporate investors at a maximum U.S. federal income tax rate of 20%. In addition, certain holders that are individuals, estates, or trusts are subject to 3.8% surtax on all or a portion of their “net investment income,” which may include all or a portion of their dividend income and net gains from the disposition of our common units. This tax treatment may be adversely affected, changed or repealed in the future and may affect market perceptions of our Company and the market price of our common units could be negatively affected.
The treatment of depreciation and other tax deductions under current U.S. federal income tax law may be adversely affected, changed, or repealed in the future.
Under current law, certain capital expenditures are eligible for accelerated depreciation, including 100% bonus depreciation for qualifying assets purchased and placed in service after September 27, 2017 and prior to January 1, 2023, for U.S. federal income tax purposes. In addition, certain other expenses are eligible to be deducted for U.S. federal income tax purposes. This tax treatment may be adversely affected, changed, or repealed by future changes in tax laws at any time, which may affect market perceptions of our Company and the market price of our common units could be negatively affected.
Our Company could be adversely affected by changes in tax laws and/or changes in the interpretation of existing tax laws.
We are subject to various taxing regimes, including federal, state, local and foreign taxes such as income, excise, sales/use, payroll, franchise, property, gross receipts, withholding, and ad valorem taxes. New tax laws and regulations and changes in existing tax laws and regulations or the interpretation thereof are continuously being enacted or proposed and could result in increased expenditures for tax in the future and could have a material adverse effect on our Company’s results of operations, cash flows, and financial condition.
Our property taxes could increase due to reassessment or property tax rate changes.
We are required to pay real property taxes in respect of our properties and such taxes may increase as our properties are reassessed by taxing authorities or as property tax rates change. An increase in the assessed value of our properties or our property tax rates may not be passed along to our customers and could adversely impact our results of operations, cash flows, and financial condition.
Our Company is subject to examinations and challenges by taxing authorities.
Periodic examinations or audits by taxing authorities could increase our tax liabilities and result in the imposition of interest and penalties. If challenges arising from such examinations and audits are not resolved in our Company’s favor, they could have a material adverse effect on our Company’s results of operations, cash flows, and financial condition.

(2)The 2014 Plan provides for the grant of director stock units. During the quarter ended June 30, 2021, the number of units available under the 2014 Plan was increased by 70,668 in accordance with the terms of the Plan as a result of the special dividend paid in connection with the IMTT Transaction. The maximum number of units available for issuance under the 2014 plan is 370,668. Only our Company’s independent directors are eligible under the 2014 Plan. Each director stock unit is an unsecured promise to transfer one unit on the settlement date, subject to satisfaction of the applicable terms and conditions. The units vest on the day prior to the following year’s annual meeting.  
(3)The 2016 Plan provides for the grant of equity awards covering up to 1,500,000 common units. The employees, consultants, and others who provide service for our Company are eligible under the 2016 Plan. Types of awards include stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights, cash-based awards, and other stock-based awards. Equity awards under the 2016 Plan generally vest no earlier than the first anniversary of the date of grant.
Subsequent to December 31, 2021, the number of units available increased to 2,481,999 and 19,259,340 under the 2014 Plan and 2016 Plan, respectively, in accordance with the terms of the Plans. The increase to the 2014 Plan is a result of the one-time distribution in connection with the AA Transaction. The increase to the 2016 Plan is a result of the special dividend paid in connection with the IMTT Transaction and the one-time distribution in connection with the AA Transaction.
Distribution Policy
Historically, we have used most of the distributable cash flow to support the payment of quarterly dividends. On April 2, 2020, in response to the effects of COVID-19 on the performance and prospects of our businesses, we suspended our quarterly cash dividend. On December 23, 2020, following the successful completion of the IMTT Transaction, our Board authorized the payment of a special dividend of $11.00 per unit in cash comprising the proceeds from the IMTT Transaction after paying or reserving for capital gains taxes, transaction costs, a Disposition Payment, and the retirement holding company level debt. On September 23, 2021, following the successful completion of the AA Transaction, our Board authorized the payment of a one-time distribution of $37.386817 per unit in cash paid out of the proceeds of the AA Transaction.
As a result of the completion of and distribution of certain proceeds from the AA Transaction in September 2021 and the signing of the Merger in June 2021, we do not expect to pay further distributions.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion of the financial condition and results of operations of Macquarie Infrastructure Holdings, LLC should be read in conjunction with the consolidated financial statements and the notes to those statements included elsewhere herein.
Recent Developments
HPUC Integrated Resource Plan Order
As anticipated, in January 2022, the HPUC issued an order requiring us to develop an Integrated Resource Plan ("IRP") in accordance with the HPUC’s Framework for Integrated Resource Planning and to file an IRP Report and Action Plan in the first quarter of 2023. The IRP will set out how we intend to meet near- and long-term energy objectives and satisfy customer needs consistent with the State’s energy policies and our goals of doing so in a safe, reliable, and cost-effective manner. We are currently reviewing the order. Under the Framework, we are entitled to recover all appropriate and reasonable integrated resource planning and implementation costs, as approved by the HPUC.
Results of Operations
Our business includes Hawaii Gas and smaller operations collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii. We generate revenue primarily from the provision of gas to commercial, residential, and governmental customers and the generation of power.
Our financial performance is a function of the number of customers served, their consumption of energy and the prices achieved on sales by each of Hawaii Gas’s utility and non-utility operations and under power purchase agreements. The amount of gas consumed is positively correlated with visitor arrivals and general economic activity over the long term. Consumption trends and prices are a function of, among other factors, energy efficiency, weather, the range of competitive energy sources, and commodity input costs.
We continue to closely monitor the effects of COVID-19 and are actively managing our response by placing a priority on the health and safety of our employees and their families, contractors, customers, and the broader communities in which we operate. Our business' operations are classified as providers of essential services, are fully operational, and are adhering to pandemic response plans and are following guidance from the Centers for Disease Control and Prevention ("CDC") as well as federal, state, and local governments with respect to conducting operations safely.
In addition to standard operating procedures designed to maintain safe operations, we have implemented additional measures including: (i) work from home and related travel policies; (ii) enhanced cleaning and disinfecting of facilities; (iii) limited interactions between employees and customers through social distancing; (iv) mandated use of personal protective equipment by employees; and (v) education of customers on alternative payment and customer care options as a means of limiting interactions with employees. Management is engaged in ongoing communications with employees, customers, vendors, lenders, and other stakeholders apprising them of the business' response to the pandemic. We believe our staff and customers of our business can access our facilities safely and in compliance with relevant directives.
Visitor arrivals to Hawaii, the primary driver of increases in demand for gas in Hawaii, improved sequentially in the fourth quarter of 2021 as increased visitor confidence levels due to the availability of COVID-19 vaccines and a relatively low level of infections in the islands combined to create an attractive environment for visitors from the U.S. mainland. The rate of recovery in the number of visitors to Hawaii in the future remains uncertain. COVID-19 continues to negatively affect the performance of the Hawaii businesses, although the effects have diminished relative to this time last year. The easing of travel restrictions has resulted in an increase in economic activity and the number of primarily domestic visitors to Hawaii, but not to pre-COVID-19 levels. A significant surge in COVID-19 rates could negatively impact the number of visitors to Hawaii, which would adversely impact our operating results.
Trends in the number of visitors to Hawaii and demand for gas were positive in the fourth quarter of 2021, although our financial performance continues to be adversely affected relative to pre-COVID-19 periods. The number of visitors to Hawaii increased to 1.9 million and 6.8 million for the quarter and year ended December 31, 2021, respectively, from 497,000 and 2.7 million for the quarter and year ended December 31, 2020, respectively. The resulting improvement in hotel occupancy, restaurants patronage, and use of commercial laundry services contributed to an increase in gas consumption of 29% and 21% during the quarter and year ended December 31, 2021, respectively, versus the comparable periods in 2020. The number of visitors to Hawaii was lower by 25% and 35% in the quarter and year ended December 31, 2021, respectively, and overall gas consumption was lower by 6% and 11% versus the comparable periods in 2019. The rate of recovery in the number of visitors to Hawaii in the future remains uncertain and a significant surge in COVID-19 cases could negatively impact Hawaii tourism.

The wholesale cost of LPG increased by approximately 60% between December 2020 and December 2021. We enter into commodity hedges to mitigate the medium to longer term impact of rising costs. The percentage of our expected LPG purchases that is hedged varies over time based on our assessment of the potential volatility in LPG costs and the duration and cost of the hedges. We pass some of our increased LPG cost through to customers in our regulated business through the fuel adjustment clause mechanism. In addition, as has been the case from time to time historically, we may pass some or all of the increased cost of LPG through to our customers in our unregulated business subject to competitive dynamics in Hawaii's energy market.
Results of Operations: 2020 vs. 2019
During the quarter ended September 30, 2021, Atlantic Aviation was classified as a discontinued operation and eliminated as a reportable segment. All periods reported herein reflect this change. For additional information, see Note 4, “Discontinued Operations and Dispositions”, in our consolidated financial statements in "Financial Statements and Supplementary Data" in Part II, Item 8, of this Form 10-K.

Revenue
We generate most of our revenue from the sale of gas. Accordingly, revenue can fluctuate based on the wholesale cost of gas and/or feedstock and may not reflect our ability to effectively manage the amount of gas sold and the margins achieved on those sales. For example, an increase in revenue may be attributable to an increase in the wholesale cost of gas and not an increase in the amount of gas sold or margin achieved. Conversely, a decline in revenue may be attributable to a decrease in the wholesale cost of gas and not a reduction in the amount of gas sold or margin achieved.
Revenue increased for 2021 compared with 2020 primarily as a result of an increase in the amount of gas sold. The increase in the amount of gas sold reflects increased consumption by commercial and industrial customers driven by an increase in the number of visitors to Hawaii and increased commercial activity as Hawaii recovers from the impact of COVID-19.
Cost of Services and Product Sales
Cost of product sales increased for 2021 compared with 2020 primarily as a result of increases in the cost of gas sold. The increase in cost of product sales was partially offset by favorable mark-to-market adjustments of the value of commodity hedge contracts for wholesale LPG.
We recorded favorable adjustments of $437,000 and $7.3 million in the mark-to-market adjustment of the value of the commodity hedge contracts for 2021 and 2020, respectively. The change in the mark-to-market adjustment of the value of the commodity hedges during 2021 primarily reflects higher forecast wholesale cost of LPG relative to the hedged cost.
As noted above, we use commodity hedges to reduce the financial risks of commodity price fluctuations associated with wholesale LPG purchases. We have entered into hedges with varying maturities through May 2024 and with respect to a varying percentage of our expected LPG purchases over that time.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased for 2021 compared with 2020 primarily as a result of (i) a disposition payment of $228.6 million paid to our Manager in connection with the AA Transaction, (ii) higher transaction costs; (iii) increases in salaries and benefits; and (iv) higher insurance costs.
Fees to Manager
Our Manager is entitled to a monthly base management fee based on our market capitalization and potentially a quarterly performance fee based on our total return relative to a U.S. utilities index. For 2021 and 2020, we incurred base management fees of $21.9 million and $21.1 million, respectively. The increase in base management fees reflects an increase in our average market capitalization and the decrease in our average holding company cash balance during 2021. No performance fees were incurred in either the current or prior comparable periods. The unpaid portion of base management fees and performance fees, if any, at the end of each reporting period is included in the line item Due to Manager-related party in our consolidated balance sheets.
In accordance with the Management Services Agreement, our Manager elected to reinvest any fees to which it was entitled in new primary units in all of the periods shown below and has currently elected to reinvest future base management fees and performance fees, if any, in new primary units.

Interest Expense, net, and Gains (Losses) on Derivative Instruments
Interest expense includes non-cash gains on derivative instruments of $333,000 in 2021 and non-cash losses of $912,000 for 2020, and the amortization of debt financing costs and debt discounts. Gains (losses) on derivatives recorded in interest expense are attributable to the change in fair value of interest rate hedges. For 2021, interest expense also includes non-cash write-offs of debt financing costs of $4.8 million related to the repurchase of our 2.00% Convertible Senior Notes, the cancellation of our holding company revolving credit facility, and the full repayment of $100.0 million of senior secured notes at Hawaii Gas.
Excluding the non-cash adjustments and write-offs, cash interest expense totaled $10.0 million and $14.5 million in 2021 and 2020, respectively. The decrease in cash interest expense primarily reflects a lower weighted average debt balance, partially offset by a $4.7 million 'make-whole' payment related to the full repayment of $100.0 million of senior secured notes at Hawaii Gas in April 2021.
Discontinued Operations
For 2021 and 2020, discontinued operations reflects the operating results of the businesses sold as part of the AA Transaction. The AA Transaction closed on September 23, 2021. For 2020, discontinued operations also reflects the operating results of IMTT. The IMTT Transaction closed on December 23, 2020.
Income Taxes
MIH is a limited liability company classified as a partnership for tax purposes. Taxable income or losses reported by MIH will be passed-through to the unitholders and reported on a Schedule K-1. MIH does not pay federal or state income tax. As a partnership, MIH itself will not pay income tax on the gain from the AA Transaction.
As part of the reorganization, the entity holding the businesses comprising MIC's MIC Hawaii segment was distributed to and became a direct subsidiary of Macquarie Infrastructure Holdings, LLC. For tax purposes, the distribution was deemed to be a sale of MIC Hawaii by MIC and unitholders were deemed to have received a distribution of the fair market value of the equity of that segment.
Our intermediate holding company is organized as a limited liability company and classified as a corporation for tax purposes. The intermediate holding company will file a consolidated federal income tax return for periods after the reorganization. The intermediate holding company will continue to file a combined Hawaii state income tax return.

Earnings Before Interest, Taxes, Depreciation, and Amortization ("EBITDA") excluding non-cash items and Free Cash Flow
In addition to our results under U.S. GAAP, we use the non-GAAP measures EBITDA excluding non-cash items and Free Cash Flow to assess the performance and prospects of our business.
We measure EBITDA excluding non-cash items as it reflects our businesses’ ability to effectively manage the amount of products sold or services provided, the operating margin earned on those transactions, and the management of operating expenses independent of our capitalization and tax position.
We believe investors use EBITDA excluding non-cash items primarily as a measure of our operating performance and to make comparisons with the operating performance of other businesses whose depreciation and amortization expense may vary from ours, particularly where acquisitions and other non-operating factors are involved. We define EBITDA excluding non-cash items as net income (loss) or earnings — the most comparable GAAP measure — before interest, taxes, depreciation and amortization, and non-cash items including impairments, unrealized derivative gains and losses, adjustments for other non-cash items, and pension expense reflected in the statements of operations. Other non-cash items, net, excludes the adjustment to bad debt expense related to the specific reserve component, net of recoveries. EBITDA excluding non-cash items also excludes base management fees and performance fees, if any, whether paid in cash or units.
We define Free Cash Flow as cash from operating activities — the most comparable GAAP measure — less maintenance capital expenditures and adjusted for changes in working capital.
We use Free Cash Flow as a measure of our ability to fund acquisitions, invest in growth projects, reduce or repay indebtedness, and/or return capital to unitholders. GAAP metrics such as net income (loss) do not provide us with the same level of visibility into our performance and prospects as a result of: (i) the capital intensive nature of our businesses and the generation of non-cash depreciation and amortization; (ii) units issued to our Manager under the Management Services Agreement; (iii) the ability of our subsidiaries to defer all or a portion of current federal income taxes; (iv) non-cash mark-to-market adjustment of the value of derivative instruments; (v) gains (losses) related to the write-off or disposal of assets or liabilities; (vi) non-cash compensation expense incurred in relation to the incentive plans for senior management of our operating businesses; and (vii) pension expenses. Pension expenses primarily consist of interest expense, expected return on plan assets, and amortization of actuarial and performance gains and losses. Any cash contributions to pension plans are reflected as a reduction to Free Cash Flow and are not included in pension expense. We believe that external consumers of our financial statements, including investors and research analysts, could use Free Cash Flow to assess our Company's ability to fund acquisitions, invest in growth projects, reduce or repay indebtedness, and/or return capital to unitholders.
We believe that both EBITDA excluding non-cash items and Free Cash Flow support a more complete and accurate understanding of the financial and operating performance of our Company than would otherwise be achieved using GAAP results alone.
Free Cash Flow does not take into consideration required payments on indebtedness and other fixed obligations or other cash items that are excluded from our definition of Free Cash Flow. We note that Free Cash Flow may be calculated differently by other companies thereby limiting its usefulness as a comparative measure. Free Cash Flow should be used as a supplemental measure to help understand our financial performance and not in lieu of our financial results reported under GAAP.
Classification of Maintenance Capital Expenditures and Growth Capital Expenditures
We categorize capital expenditures as either maintenance capital expenditures or growth capital expenditures. As neither maintenance capital expenditure nor growth capital expenditure is a GAAP term, we have adopted a framework to categorize specific capital expenditures. In broad terms, maintenance capital expenditures primarily maintain our business at current levels of operations, capability, profitability or cash flow, while growth capital expenditures primarily provide new or enhanced levels of operations, capability, profitability or cash flow. We consider various factors in determining whether a specific capital expenditure will be classified as maintenance or growth.
We do not bifurcate specific capital expenditures into maintenance and growth components. Each discrete capital expenditure is considered within the above framework and the entire capital expenditure is classified as either maintenance or growth.

Liquidity and Capital Resources
General
Cash requirements of our business includes primarily normal operating expenses, debt service, debt principal payments, and capital expenditures.
We may from time to time seek to purchase or retire our outstanding debt in open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on market conditions, our liquidity needs, and other factors.
2.00% Convertible Senior Notes
On February 17, 2021, we initiated a tender offer for any and all of our 2.00% Convertible Senior Notes outstanding. On March 16, 2021, we repurchased $358.6 million in aggregate principal amount of the Notes in the tender offer. During the second quarter of 2021, we repurchased an additional $9.9 million of Notes in the open market and reduced the outstanding balance to $34.0 million. On September 23, 2021, we initiated an offer to repurchase any and all Notes outstanding and on October 22, 2021, we repurchased $26.9 million in aggregate principal amount of the Notes outstanding. On December 31, 2021, we had $6.8 million of 2.00% Convertible Senior Notes outstanding.
Hawaii Gas Senior Secured Notes
On April 19, 2021, Hawaii Gas fully repaid all of its $100.0 million senior secured notes outstanding and incurred a $4.7 million 'make-whole' payment.
Ongoing Operations
We currently expect to service and/or repay our debts, make required tax payments, fund maintenance capital expenditures, and deploy growth capital during 2022 using cash generated from operations and cash on hand.
Debt
On December 31 2021 our consolidated debt outstanding totaled $99.5 million. We had access to an undrawn revolving credit facility of $60.0 million. The ratio of net debt/EBITDA excluding non-cash items for our continuing operations was 1.33x on December 31, 2021.

Historical Cash Flows: 2020 vs. 2019
During the quarter ended September 30, 2021, Atlantic Aviation was classified as a discontinued operation and eliminated as a reportable segment. All periods reported herein reflect this change. For additional information, see Note 4, “Discontinued Operations and Dispositions”, in our consolidated financial statements in "Financial Statements and Supplementary Data" in Part II, Item 8, of this Form 10-K.
For a comparison and discussion of our consolidated liquidity and capital resources and our cash flow activities for 2020 compared with 2019, see "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7, in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the U.S. Securities and Exchange Commission on February 17, 2021.
Operating Activities from Continuing Operations
Cash provided by (used in) operating activities is generally comprised of EBITDA excluding non-cash items (as defined by us), less cash interest, cash taxes, and pension payments, and changes in working capital. See “Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations” for discussions around the components of EBITDA excluding non-cash items on a consolidated basis.
The increase in consolidated cash used in operating activities in 2021 compared with 2020 was primarily due to:
a decrease in EBITDA excluding non-cash items, primarily due to the disposition payment and transaction costs incurred and paid during 2021;
an unfavorable change to accounts receivable and inventory and favorable change to accounts payable resulting from the decline in business activity and cost of gas from the impact of COVID-19 during 2020; partially offset by
an increase in benefit for current taxes;
a decrease in cash interest expense.
We believe our operating activities overall provide a source of sustainable and stable cash flows over the long-term as a result of:
consistent customer demand driven by the basic nature of the products sold;
our strong competitive position due to factors including:
high initial development and construction costs;
difficulty in obtaining suitable land on which to operate;
government franchise, leases, or customer contracts;
required government approvals, which may be difficult or time-consuming to obtain;
lack of immediate cost-effective alternatives for the products sold; and

product pricing that we expect will keep pace with cost increases as a result of the basic nature of the products sold.
Investing Activities from Continuing Operations
Cash provided by investing activities include proceeds from divestitures of businesses and disposal of fixed assets. Cash used in investing activities include acquisitions of businesses in new and existing segments and capital expenditures.
The decrease in cash used in investing activities for 2021 compared with 2020 is primarily attributable to lower capital expenditures.
Financing Activities from Continuing Operations
Cash provided by financing activities includes new equity and debt issuances. Cash used in financing activities includes distributions paid to our equityholders and the repayment of debt principal.
The increase in cash used in financing activities for 2021 compared with 2020 is primarily attributable to a special dividend of $11.00 per unit declared and paid out of the proceeds from the IMTT Transaction in January 2021, a one-time distribution of $37.386817 per unit declared and paid out of the proceeds from the AA Transaction in October 2021, repurchase of a portion of our 2.00% Convertible Senior Notes outstanding, and the full repayment of $100.0 million senior secured notes at Hawaii Gas.

TABLE OF CONTENTS
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The preparation of our financial statements requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from these estimates under different assumptions and judgments and uncertainties, and potentially could result in materially different results under different conditions. Our critical accounting policies and estimates are discussed below. These estimates and policies are consistent with the estimates and accounting policies followed by the businesses we own and operate.
Business Combinations
Our acquisitions of businesses that we control are accounted for under the purchase method of accounting. The amounts assigned to the identifiable assets acquired and liabilities assumed in connection with acquisitions are based on estimated fair values as of the date of the acquisition, with the remainder, if any, recorded as goodwill. The fair values are determined by our management, taking into consideration information supplied by the management of acquired entities and other relevant information. Such information includes valuations supplied by independent appraisal experts for significant business combinations. The valuations are generally based upon future cash flow projections for the acquired assets, discounted to a present value. The determination of fair values requires significant judgment both by management and outside experts engaged to assist in this process.
Goodwill, Intangible Assets and Property, Plant and Equipment
Significant assets acquired in connection with our acquisition of businesses include contractual arrangements, customer relationships, non-compete agreements, trademarks, property and equipment, and goodwill.
Goodwill and Trademarks
Trademarks are generally considered to be indefinite life intangibles. Trademarks and goodwill are not amortized in most circumstances although it may be appropriate to amortize some trademarks. We are required to perform annual impairment reviews (or more frequently in certain circumstances) for unamortized intangible assets.
ASU No. 2011-08, Intangibles — Goodwill and Other (Topic 350): Testing Goodwill for Impairment, permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test, as discussed below. If an entity concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it need not perform the two-step impairment test.
ASU No. 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, simplifies the measurement of goodwill and no longer requires an entity to perform a hypothetical purchase price allocation when computing the estimated fair value to measure goodwill impairment. Instead, impairment will be assessed by quantifying the difference between the fair value of a reporting unit and its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, on condition that the charge doesn’t exceed the total amount of goodwill allocated to that reporting unit.
If an entity concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if there is a triggering event that indicates impairment, the entity needs to perform a quantitative impairment test. This requires management to make judgments in determining what assumptions to use in the calculation. The first step is to determine the estimated fair value of each reporting unit with goodwill.
The Company estimates the fair value by estimating the present value of the future discounted cash flows or value expected to be realized in a third-party sale. If the recorded net assets are less than the estimated fair value, then no impairment is indicated. If the recorded amount of goodwill exceeds the estimated fair value, an impairment charge is recorded for the excess.
The impairment test for trademarks, which are not amortized, requires the determination of the fair value of such assets. If the fair value of the trademarks is less than their carrying value, an impairment loss is recognized in an amount equal to the difference. We cannot predict the occurrence of certain future events that might adversely affect the reported value of goodwill and/or intangible assets. Such events include, but are not limited to, the potential failure to complete the Merger, strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on our customer base, or a material negative change in relationship with significant customers.
We test for goodwill impairment on October 1 of each year and between annual tests if a triggering event indicates the possibility of an impairment. We monitor changing business conditions as well as industry and economic factors, among others, for events which could trigger the need for an interim impairment analysis. With the signing of the Merger, the Company will evaluate goodwill for impairment having regard to the Merger transaction value. On December 31, 2021, there were no new triggering events that indicated impairment.

TABLE OF CONTENTS
Property, Plant and Equipment and Intangible Assets
Property and equipment is initially stated at cost. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the property and equipment after consideration of historical results and anticipated results based on our current plans. Our estimated useful lives represent the period the asset remains in service assuming normal routine maintenance. We review the estimated useful lives assigned to property and equipment when our business experience suggests that they do not properly reflect the consumption of economic benefits embodied in the property and equipment nor result in the appropriate matching of cost against revenue. Factors that lead to such a conclusion may include physical observation of asset usage, examination of realized gains and losses on asset disposals, and consideration of market trends such as technological obsolescence or change in market demand.
Significant intangibles, including contractual arrangements, customer relationships, non-compete agreements, and technology are amortized using the straight-line method over the estimated useful lives of the intangible asset after consideration of historical results and anticipated results based on our current plans.
We perform impairment reviews of property and equipment and intangibles subject to amortization when events or circumstances indicate that fair value of the assets are less than their carrying amount and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. In this circumstance, the impairment charge is determined based upon the amount by which the net book value of the assets exceeds their fair market value. Any impairment is measured by comparing the fair value of the asset to its carrying value.
The estimated fair value of property and equipment and intangible assets is determined by our management and is generally based upon future cash flow projections for the acquired assets, discounted to present value. We use outside valuation experts when management considers that it is appropriate to do so.
We test for goodwill and indefinite-lived intangible assets annually as of October 1 or when there is an indicator of impairment. See Note 7, “Property, Equipment, Land and Leasehold Improvements”, and Note 8, “Intangible Assets and Goodwill”, in our consolidated financial statements in “Financial Statements and Supplementary Data” in Part II, Item 8, of this Form 10-K for financial information and further discussion.

Accounting Policies, Accounting Changes, and Future Application of Accounting Standards
See Note 2, “Summary of Significant Accounting Policies”, in our consolidated financial statements in “Financial Statements and Supplementary Data” in Part II, Item 8, of this Form 10-K for financial information and further discussion and for a summary of the Company’s significant accounting policies, including a discussion of recently adopted and issued accounting pronouncements.
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The discussion that follows describes our exposure to market risks and the use of derivatives to address those risks. See Note 10, “Derivative Instruments and Hedging Activities”, in Part II, Item 8, of this Form 10-K for further discussions.
Interest Rate Risk
We are exposed to interest rate risk in relation to the borrowings of our business. We may enter into derivative financial instruments to fix variable-rate interest payments covering a portion of the interest rate risk associated with the borrowings of our business, subject to the requirements of our lenders.
Changes in interest rates impact our interest expense on both the hedged and unhedged portion of our debt. Interest expense on the unhedged portion of our debt changes with the variation in interest rates applied to the outstanding balance of the debt. This has a corresponding impact on the amount of cash interest we pay and our effective cash interest rate. Interest expense on the hedged portion of our debt changes by the variation in the fair value of the underlying interest rate contracts. This has no impact on the amount of cash interest we pay or our effective cash interest rate.
As of December 31, 2021, our Company had $99.5 million of current and long-term debt outstanding, of which $12.7 million was economically hedged with interest rate contracts, $6.8 million was fixed rate debt, and $80.0 million was unhedged. The interest rate on Hawaii Gas' $80.0 million term loan facility floats at LIBOR plus 1.25%. A 10% decrease in interest rates would result in an $8,000 decrease in interest expense per year and a corresponding 10% increase would result in a $8,000 increase in interest expense per year.
The interest rate on the solar power generation facilities' $12.7 million term loan facility floats at LIBOR plus 2.00% and is fixed at 3.38% using an interest rate swap contract through June 2026. A 10% decrease in interest rates would result in a $52,000 decrease in the fair market value of the interest rate swaps and an corresponding 10% increase would result in a $86,000 increase in the fair market value.
The LIBOR reference rate reform transition deadline is June 30, 2023 for our derivative securities and debt facilities that are marked to the one-month LIBOR rate. Management is currently evaluating the options and is not expecting the transition to have a material impact on its contracts.
Commodity Price Risk
The risk associated with fluctuations in the prices that Hawaii Gas pays for LPG is principally a result of market forces reflecting changes in supply and demand for LPG. Hawaii Gas’ gross margin is sensitive to changes in LPG supply costs and Hawaii Gas may not always be able to pass through product cost increases fully or on a timely basis, particularly when product costs rise rapidly. To reduce the volatility of the business’ LPG market price risk, Hawaii Gas has used and expects to continue to use over-the-counter commodity derivative instruments including price swaps. Hawaii Gas does not use commodity derivative instruments for speculative or trading purposes. Over-the-counter derivative commodity instruments utilized by Hawaii Gas to hedge forecasted purchases of LPG are generally settled at expiration of the contract. The fair value of unsettled commodity price risk sensitive instruments on December 31, 2021 was an asset of approximately $1.4 million. A 10% increase in the market price of LPG would result in an increase in such fair value of approximately $5.6 million. A 10% decrease in the market price of LPG would result in a decrease in such fair value of approximately $5.6 million.

Report of Independent Registered Public Accounting Firm

To the Unitholders and Board of Directors
Macquarie Infrastructure Holdings, LLC:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Macquarie Infrastructure Holdings, LLC and subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), unitholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 22, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Change in Accounting Principle
As discussed in Notes 2 and 9 to the consolidated financial statements, the Company has changed its method of accounting for convertible instruments as of January 1, 2021 due to the adoption of Accounting Standards Update (ASU) No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40).
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Evaluation of the sufficiency of audit evidence obtained over revenue
As discussed in Note 12 to the consolidated financial statements, and disclosed in the consolidated statements of operations, the Company recorded $236 million of product revenue from continuing operations for the year ended December 31, 2021. As discussed in Note 4 to the consolidated financial statements, the Company recorded $678 million of service revenue from discontinued operations. We identified the evaluation of the sufficiency of audit evidence obtained over revenue as a critical audit matter. A higher degree of auditor judgment was required to determine the revenue streams over which procedures would be performed and to evaluate the nature and extent of audit evidence obtained over each revenue stream due to the multiple revenue streams and the use of multiple processes to record revenue. The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the
44

TABLE OF CONTENTS
nature and extent of procedures to be performed over revenue, including the determination of the revenue streams over which those procedures were performed. For each revenue stream where procedures were performed, we evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process to record revenue. For certain revenue streams, we assessed the recorded revenue by:
selecting a sample of transactions and comparing the revenue recorded for consistency with underlying documentation.
comparing recorded revenue to an expectation of revenue developed using volumes and regulatory rates, including evaluating the relevance and reliability of the inputs to the expectation.
comparing the total cash received during the year to the revenue recorded, including evaluating the relevance and reliability of total cash received.
In addition, we evaluated the sufficiency of audit evidence obtained over revenue by assessing the results of procedures performed, including the appropriateness of the nature and extent of such evidence.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1.  i Organization and Description of Business
Macquarie Infrastructure Holdings, LLC ("MIH") is a Delaware limited liability company formed on February 5, 2021 and the registrant since September 22, 2021. MIH is the successor to Macquarie Infrastructure Corporation ("MIC"), a Delaware corporation formed on May 21, 2015. MIC’s predecessor, Macquarie Infrastructure Company LLC, was formed on April 13, 2004. Except as otherwise specified, all references in this Form 10-K to "MIH" or the "Company" refers to Macquarie Infrastructure Holdings, LLC and its subsidiaries, or as necessary when referring to previous reporting periods or the period prior to September 22, 2021, MIC and its subsidiaries.
MIH is externally managed by Macquarie Infrastructure Management (USA) Inc. (the "Manager"), pursuant to the terms of a Management Services Agreement, subject to the oversight and supervision of the Board. Six of the eight members of the Board, and all members of each of the Company's Audit, Compensation, and Nominating and Governance Committees, are independent and have no affiliation with Macquarie. The Manager is a member of the Macquarie Group of companies comprising Macquarie Group Limited and its subsidiaries and affiliates worldwide. Macquarie Group Limited is headquartered in Australia and is listed on the Australian Securities Exchange.
The Company owns and operates businesses that provide products to corporations, government agencies, and individual customers in Hawaii. The Company's operations consist of businesses comprising an energy company that processes and distributes gas and provides related services, Hawaii Gas, and several smaller operations collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii.
In October 2019, along with actively managing its existing portfolio of businesses, the Board resolved to pursue strategic alternatives including potentially a sale of the Company or its then  i three operating businesses as a means of unlocking additional value for equity holders.
During the quarter ended September 30, 2020, the Company's International-Matex Tank Terminals ("IMTT") business was classified as a discontinued operation and eliminated as a reportable segment. All periods reported herein reflect this change. In December 2020, the Company completed the sale of IMTT (the "IMTT Transaction"). For additional information, see Note 4, “Discontinued Operations and Dispositions”.
On June 7, 2021, the Company entered into an agreement for the sale of its Atlantic Aviation business to KKR Apple Bidco, LLC, a Delaware limited liability company controlled by funds affiliated with Kohlberg Kravis Roberts & Co. L.P. (“KKR”), for $ i 4.475 billion including cash and the assumption of debt and other transaction and reorganization related obligations (the "AA Transaction").
On June 14, 2021, the Company entered into a merger agreement (the "Merger Agreement") with AMF Hawaii Holdings, LLC ("AMF Parent"), a Delaware limited liability company affiliated with Argo Infrastructure Partners, LP ("Argo"), and AMF Hawaii Merger Sub, LLC ("AMF Merger Sub"), a recently formed Delaware limited liability company and wholly-owned direct subsidiary of AMF Parent (the "Merger"). Upon the completion of the Merger, each of the MIH common units (excluding common units held by AMF Parent or AMF Merger Sub or common units held by MIH in treasury and common units held by any subsidiary of MIH or AMF Parent (other than AMF Merger Sub)), will be converted into the right to receive $ i 3.83 in cash, without interest; or, if the Merger is consummated after July 1, 2022, then each such unit will be converted into the right to receive $ i 4.11 in cash, without interest.
Under the terms of the Merger Agreement, at closing, AMF Parent will pay the merger consideration to unitholders, and fund transaction costs and fund a disposition payment to MIH’s Manager of $ i 81.7 million if the Merger closes on or before July 1, 2022 or $ i 56.7 million if the Merger closes after this date.
On September 21, 2021, the Company conducted a Special Meeting of Shareholders during which shareholders voted on and approved the AA Transaction and the Merger. As a result, MIH classified its Atlantic Aviation business as a discontinued operation.
On September 22, 2021, shareholders of Macquarie Infrastructure Corporation became unitholders of Macquarie Infrastructure Holdings, LLC, a limited liability company treated as a partnership for tax purposes, on a  i one-for-one basis without an exchange of certificates. Commencing September 23, 2021, units of Macquarie Infrastructure Holdings, LLC traded on the New York Stock Exchange ("NYSE") under the same symbol (NYSE: MIC) and with the same CUSIP number (55608B105) as previously associated with shares of Macquarie Infrastructure Corporation.
As part of the reorganization, the entity holding the businesses comprising MIC's MIC Hawaii segment was distributed to and became a direct subsidiary of Macquarie Infrastructure Holdings, LLC. For tax purposes, the distribution was deemed to be

a sale of MIC Hawaii by MIC and unitholders were deemed to have received a distribution of the fair market value of the equity of that segment.
On September 23, 2021, MIH completed the AA Transaction, and received $ i 3.525 billion at the closing. The MIH Board elected to return certain proceeds from the AA Transaction to unitholders, declaring a one-time distribution of $ i 37.386817 per common unit of the Company, paid on October 7, 2021 to unitholders of record as of the close of trading on October 4, 2021. The Company's common units traded with due-bills attached from October 1, 2021 through October 7, 2021 pursuant to relevant NYSE rules. In addition, MIH made a disposition payment to the Manager of $ i 228.6 million. See Note 4, “Discontinued Operations and Dispositions” for further information.
The Merger is expected to be completed in the first half of 2022 subject to the approval by the Hawaii Public Utilities Commission ("HPUC") and the satisfaction of customary closing conditions for this type of transaction. Upon the closing of the Merger, the Company will no longer be a publicly traded entity.
2.  i Summary of Significant Accounting Policies
 i 
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company consolidates investments where it has a controlling financial interest. The general condition for a controlling financial interest is ownership of a majority of the voting interest and, therefore, as a general rule, ownership, directly or indirectly, of over 50% of the outstanding voting shares is a condition for consolidation. In addition, if the Company demonstrates that it has the ability to direct policies and management, this may be also an indication for consolidation. For investments in variable interest entities, the Company consolidates when it is determined to be the primary beneficiary of the variable interest entity. The Company is the primary beneficiary in the solar facilities in Hawaii and consolidated these projects accordingly.
 i 
Use of Estimates
The preparation of the consolidated financial statements, which are in conformity with generally accepted accounting principles ("GAAP"), requires the Company to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. The Company evaluates these estimates and judgments on an ongoing basis and the estimates are based on experience, current and expected future conditions, third-party evaluations, and various other assumptions that the Company believes are reasonable under the circumstances. Significant items subject to such estimates and assumptions include the carrying amount of property, equipment, land, and leasehold improvements, intangibles, and goodwill; assets and obligations related to employee benefits; and valuation of derivative instruments. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from the estimates and assumptions used in the financial statements and related notes.
 i 
Business Combinations
Acquisitions of businesses that the Company controls are accounted for under the purchase method of accounting. The amounts assigned to the identifiable assets acquired and liabilities assumed in connection with acquisitions are based on estimated fair values as of the date of the acquisition, with the remainder, if any, recorded as goodwill. The fair values are determined by the Company’s management, taking into consideration information supplied by the management of acquired entities and other relevant information. Such information includes valuations supplied by independent appraisal experts for significant business combinations. The valuations are generally based upon future cash flow projections for the acquired assets, discounted to a present value. The determination of fair value requires significant judgment both by management and outside experts engaged to assist in this process.
 i 
Cash and Cash Equivalents
The Company considers all highly liquid investments, including commercial paper issued by counterparties with Standard & Poor's rating of A1+ or higher, with maturity of three months or less when purchased to be cash and cash equivalents. The Company did  i  i no / t have any investments in commercial paper on December 31, 2021 and 2020.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
2. Summary of Significant Accounting Policies  – (continued)
 i Restricted Cash
On December 31, 2021 and 2020, restricted cash consists primarily of deposits held by banks to fund certain obligations under its agreements in place at the solar facilities in Hawaii.
 i 
Allowance for Doubtful Accounts
The Company uses estimates to determine the amount of allowance for doubtful accounts necessary to reduce accounts receivable to its net realizable value. The Company estimates the required allowance by reviewing the status of past-due receivables and analyzing historical bad debt trends. Actual collection experience has not varied significantly from estimates primarily due to credit policies and a lack of concentration of accounts receivable. The Company writes-off receivables deemed to be uncollectible to the allowance for doubtful accounts.
 i 
Inventory
Inventory consists principally of gas purchased from various third-party vendors and materials and supplies. Gas inventory is stated at the lower of cost or market and materials and supplies inventory are valued at the lower of average cost or market. Inventory sold is recorded using an average cost method at the businesses in Hawaii. Cash flows related to the sale of inventory are classified in net cash provided by operating activities in the consolidated statements of cash flows.
The Company’s inventory balance on December 31, 2021 comprised $ i 4.6 million of inventory for sale and $ i 7.1 million of materials and supplies compared with $ i 2.3 million of inventory for sale and $ i 7.3 million of materials and supplies on December 31, 2020.
 i 
Property, Equipment, Land, and Leasehold Improvements
Property, equipment, land, and leasehold improvements are initially recorded at cost. Major renewals and improvements are capitalized while repair and maintenance expenditures are expensed when incurred. Interest expense relating to construction in progress is capitalized as an additional cost of the asset. The Company depreciates property, equipment, and leasehold improvements over their estimated useful lives on a straight-line basis. The estimated economic useful lives range is up to  i  i  i  i 68 /  /  /  years for buildings, leasehold and land improvements, machinery and equipment, and furniture and fixtures.
 / 
 i 
Goodwill and Intangible Assets
Goodwill consists of costs in excess of the aggregate purchase price over the fair value of tangible and identifiable intangible net assets acquired in business combinations. The cost of intangible assets with determinable useful lives is amortized over their estimated useful lives of  i 20 years.
 / 
 i 
Impairment of Long-lived Assets, Excluding Goodwill
Long-lived assets, including amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group of assets may not be fully recoverable. These events or changes in circumstances may include a significant deterioration of operating results, changes in business plans, or changes in anticipated future cash flows. If an impairment indicator is present, the Company evaluates recoverability by comparing the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the fair value of the assets. Fair value is generally determined by estimates of discounted cash flows or value expected to be realized in a third-party sale. The discount rate used in any estimate of discounted cash flows would be the rate required for a similar investment of like risk.
 i 
Impairment of Goodwill
Goodwill is tested for impairment at least annually on October 1 or when there is a triggering event that indicates the possibility of an impairment. For the annual impairment test, an entity can make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before performing a quantitative goodwill impairment test, as discussed below. If an entity concludes it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, it need not perform the quantitative impairment test.
If an entity concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if there is a triggering event that indicates impairment, the entity needs to perform a quantitative impairment test. This requires management to make judgments in determining what assumptions to use in the calculation.

MACQUARIE INFRASTRUCTURE HOLDINGS, LLC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
2. Summary of Significant Accounting Policies  – (continued)
The Company estimates the fair value by estimating the present value of the future discounted cash flows or value expected to be realized in a third-party sale. If the recorded net assets are less than the estimated fair value, then no impairment is indicated. If the recorded amount of goodwill exceeds the estimated fair value, an impairment charge is recorded for the excess. See Note 8, “Intangible Assets and Goodwill”, for further discussions on goodwill impairment testing.
 i Leases
The Company accounts for leases in accordance with ASC 842, Leases, which requires a lessee to recognize on its balance sheet the right-of-use ("ROU") assets and lease liabilities with lease terms of more than 12 months. The substantial population of the Company’s ROU assets and lease liabilities related to Atlantic Aviation’s operating leases of land, buildings, and certain equipment, which are included in assets and liabilities held for sale as of December 31, 2020. ROU assets represent the Company’s right to use an underlying asset for the lease term and the lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. The Company has made an accounting policy election to keep leases with an initial term of 12 months or less off the balance sheet and has elected the practical expedient whereby the Company will not separate a qualifying contract into its lease and non-lease components. See Note 5, "Leases", for further disclosure on operating leases.
 i 
Impairment of Indefinite-lived Intangibles, Excluding Goodwill
Indefinite-lived intangibles, which consist of trademarks, are considered impaired when the carrying amount of the asset exceeds its estimated fair value. The Company estimates the fair value of each trademark using the relief from royalty method that discounts the estimated net cash flows the Company would have to pay to license the trademark under an arm’s length licensing agreement. If the recorded indefinite-lived intangible is less than its estimated fair value, then no impairment is indicated. Alternatively, if the recorded intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
 i 
Debt Financing Costs
The Company capitalizes all direct costs incurred in connection with the issuance of debt as debt financing costs. On December 31, 2021, these costs are amortized over the contractual term of the debt instrument which ranges from  i 4 to  i 10 years with a weighted average remaining life of  i 2.9 years.
 / 
 i 
Derivative Instruments
From time to time the Company enters into interest rate derivative agreements to minimize potential variations in cash flows resulting from fluctuations in interest rates and their impact on its variable-rate debt. Hawaii Gas enters into commodity cost hedges to mitigate the impact of fluctuations in liquefied petroleum gas ("LPG") prices on its cash flows.
The Company accounts for derivatives and hedging activities in accordance with Accounting Standard Codification ("ASC") 815, Derivatives and Hedging, which requires that all derivative instruments be recorded on the balance sheet at their respective fair values. All movements in the fair value of derivative contracts are recorded directly through earnings. See Note 10, “Derivative Instruments and Hedging Activities”, for further discussions.
 i 
Financial Instruments
The Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and variable-rate senior debt, are carried at cost, which approximates their fair value because of either the short-term maturity, or competitive interest rates assigned to these financial instruments. The fair values of the Company’s other debt instruments fall within level 1 or level 2 of the fair value hierarchy.
 i 
Concentrations of Credit Risk
Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company places its cash and cash equivalents with financial institutions and its balances may exceed federally insured limits. The Company’s accounts receivable balances are mainly derived from gas sales rendered under contract terms with commercial and private customers located in the United States. On December 31, 2021 and 2020, there were no outstanding accounts receivable due from a single customer that accounted for more than 10% of the total accounts receivable. Additionally, no single customer accounted for more than 10% of the Company’s revenue in 2021, 2020, and 2019.

The assets and liabilities of IMTT’s Newfoundland and Quebec locations were translated from their local currency (Canadian dollars) to U.S. dollars at exchange rates in effect at the end of the reporting period and consolidated statement of operations accounts are translated at average exchange rates for the reporting period. Translation gains or losses as a result of changes in the exchange rate were recorded as a component of other comprehensive income (loss) through the date of sale.
 i Accrued Expenses
Accrued expenses of $ i 18.4 million and $ i 17.8 million on December 31, 2021 and 2020, respectively, primarily consisted of payroll and related liabilities, interest, non-income related taxes, insurance, purchase of property and equipment, and other individually insignificant balances.
 i 
Income per Unit
The Company calculates income per unit using the weighted average number of common units outstanding during the period. Diluted income per unit is computed using the weighted average number of dilutive common equivalent units outstanding during the period. Common equivalent units may consist of (i) units issuable upon conversion of the Company’s convertible senior notes (using the if-converted method); (ii) director share units granted to the Company’s independent directors under the 2014 Independent Directors Equity Plan; (iii) stock units granted to certain employees of the Company's operating businesses under the 2016 Omnibus Employee Incentive Plan; and (iv) fees payable to the Manager that will be reinvested in common units by the Manager in a future period, if any. Common equivalent units are excluded from the calculation if their effect is anti-dilutive.
 i 
Comprehensive Income (Loss)
The Company follows the requirements of ASC 220, Comprehensive Income, for the reporting and presentation of comprehensive income (loss) and its components, net of taxes. For the Company, the guidance requires unrealized gains or losses on foreign currency translation adjustments and minimum pension liability adjustments to be included in other comprehensive income (loss), net of taxes.
 i 
Regulatory Assets and Liabilities
The utility operations of Hawaii Gas are subject to regulation with respect to rates, service, maintenance of accounting records, and various other matters by the HPUC. The established accounting policies recognize the financial effects of the rate-making and accounting practices and policies of the HPUC. Regulated utility operations are subject to the provisions of ASC 980, Regulated Operations. This guidance requires regulated entities to disclose in their financial statements the authorized recovery of costs associated with regulatory decisions. Accordingly, certain costs that otherwise would normally be charged to expense may, in certain instances, be recorded as an asset in a regulatory entity’s balance sheet. The Hawaii Gas business records regulatory assets as costs that have been deferred for which future recovery through customer rates may be approved by the HPUC in a future proceeding. Regulatory liabilities represent amounts included in rates and collected from customers for costs expected to be incurred in the future.
ASC 980 may, at some future date, be deemed inapplicable because of changes in the regulatory and competitive environments or other factors. If the Company were to discontinue the application of this guidance, the Company would be required to write-off its regulatory assets and regulatory liabilities and would be required to adjust the carrying amount of any other assets, including property, plant, and equipment, that would be deemed not recoverable related to these affected operations. The Company believes its regulated operations in the Hawaii Gas business continue to meet the criteria of ASC 980 and that the carrying value of its regulated property, plant, and equipment is recoverable in accordance with established HPUC rate-making practices.
 i 
Income Taxes
MIH is a limited liability company treated as a partnership for tax purposes. Taxable income/losses reported by MIH will be passed-through to the unitholders and reported on a Schedule K-1. MIH does not pay a state or federal income tax. As a partnership, MIH itself will not pay income tax on the gain from the AA Transaction.
As part of the reorganization, the entity holding the businesses comprising MIC's MIC Hawaii segment was distributed to and became directly owned by MIH. For tax purposes, the distribution was deemed to be a sale and unitholders were deemed to have received a distribution of the fair market value of the equity of MIC's MIC Hawaii segment.

2. Summary of Significant Accounting Policies  – (continued)
Following the reorganization, the subsidiaries of the Company are owned by an intermediate holding company organized as a limited liability company and classified as a corporation for tax purposes. The intermediate holding company files a combined Hawaii state income tax return and will file a consolidated federal income tax return for the periods after the reorganization.
The intermediate holding company accounts for income taxes using the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The intermediate holding company and its more than  i 80% owned subsidiaries will file a consolidated U.S. federal income tax return.
In assessing the need for a valuation allowance, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.
 i 
Reclassifications
Certain reclassifications were made to the consolidated financial statements for the prior periods to conform to current year presentation.
 i 
Recently Issued Accounting Standards
In August 2020, the FASB issued ASU No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). The amendments in this ASU impact the accounting for convertible instruments by reducing the number of accounting models used to account for these instruments and amending diluted earnings per share calculations. It also simplifies the requirements for contracts indexed to and potentially settled in an entity's own equity. The amendments in this update are effective for fiscal years ending after December 15, 2021. Early adoption is permitted. The Company adopted this ASU on January 1, 2021 using the modified retrospective method and made an adjustment to the beginning balance to Retained Earnings. The impact of this ASU has been reflected in the consolidated financial statements and disclosures related to the Company's convertible debt instruments. See Note 9, "Long-Term Debt", for further discussions.
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting, which provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London interbank offered rate ("LIBOR") or another reference rate expected to be discontinued as a result of reference rate reform. In January 2021, the FASB also issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. These amendments are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. ASU No. 2020-04 and ASU No. 2021-01 are effective as of March 12, 2020 and through December 31, 2022, and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company is currently evaluating the impact of adoption on its financial statements and related disclosures.
3.  i Impact of COVID-19
Visitor arrivals to Hawaii, the primary driver of increases in demand for gas in Hawaii, improved sequentially in the fourth quarter of 2021 as increased visitor confidence levels due to the availability of COVID-19 vaccines and a relatively low level of infections in the islands combined to create an attractive environment for visitors from the U.S. mainland. The rate of recovery in the number of visitors to Hawaii in the future remains uncertain. COVID-19 continues to negatively affect the performance of the Hawaii businesses, although the effects have diminished relative to this time last year. The easing of travel restrictions has resulted in an increase in economic activity and the number of primarily domestic visitors to Hawaii, but not to pre-COVID-19 levels. A significant surge in COVID-19 rates could negatively impact the number of visitors to Hawaii, which would adversely impact our operating results.

3. Impact of COVID-19  – (continued)
Trends in the number of visitors to Hawaii and demand for gas were positive in the fourth quarter of 2021, although the financial performance of the Company continues to be adversely affected relative to pre-COVID-19 periods. The number of visitors to Hawaii increased to  i 1.9 million and  i 6.8 million for the quarter and year ended December 31, 2021, respectively, from  i 497,000 and  i 2.7 million for the quarter and year ended December 31, 2020, respectively. The resulting improvement in hotel occupancy, restaurants patronage, and use of commercial laundry services contributed to an increase in gas consumption of  i 29% and  i 21% during the quarter and year ended December 31, 2021, respectively, versus the comparable periods in 2020. The number of visitors to Hawaii was lower by  i 25% and  i 35% in the quarter and year ended December 31, 2021, respectively, and overall gas consumption was lower by  i 6% and  i 11% versus the comparable periods in 2019.
4.  i Discontinued Operations and Dispositions
The Company accounts for disposals that represent a strategic shift that should have or will have a major effect on operations as discontinued operations in the consolidated statements of operations commencing in the period in which the business or group of businesses meets the criteria of a discontinued operation. These results include any gain or loss recognized on disposal or adjustment of the carrying amount to fair value less cost to sell.
AA Transaction
On September 23, 2021, MIH completed the AA Transaction for $ i 4.475 billion including cash and the assumption of debt and other transaction and reorganization related obligations. The Company received $ i 3.525 billion from KKR at the closing of the AA Transaction.
The MIH Board elected to return certain proceeds from the AA Transaction to unitholders in a one-time distribution, after a disposition payment by MIH to the Manager of $ i 228.6 million. The Board declared a one-time distribution of $ i 37.386817 per common unit of the Company, paid on October 7, 2021 to unitholders of record as of the close of trading on October 4, 2021.
The sale of Atlantic Aviation was part of the Company's efforts to unlock value for its unitholders. On September 21, 2021, the shareholders of MIC approved the AA Transaction at the Special Meeting and therefore the Company determined that each of the criteria to be classified as held for sale under ASC 205-20, Presentation of Financial Statements — Discontinued Operations, had been met as it relates to Atlantic Aviation. It was additionally determined that the sale of Atlantic Aviation is considered a strategic shift for the Company that will have a major effect on operations. Accordingly, Atlantic Aviation was classified as a discontinued operation and the Atlantic Aviation segment was eliminated. All prior periods have been restated to reflect these changes.
The Company recognized a book gain on sale of approximately $ i 2.95 billion as a result of the AA Transaction. The Company incurred $ i 50.2 million in transaction costs and a disposition payment of $ i 228.6 million to its Manager, both of which are included in Selling, general and administrative expenses in the consolidated statement of operations.
 i A summary of assets and liabilities held for sale included in the Company's consolidated balance sheet related to the Atlantic Aviation business ("AA Business") as of December 31, 2020 are as follows ($ in thousands):

IMTT Transaction
On December 23, 2020, the Company completed the sale of IMTT to an affiliate of Riverstone Holdings, LLC for $ i 2.67 billion, net of closing adjustments, and including assumed debt including accrued interest of approximately $ i 1.11 billion. The net proceeds of $ i 1.55 billion were used to: (i) pay a special dividend of $ i 11.00 per unit on January 8, 2021; (ii) pay capital gains taxes in April 2021; (iii) pay transaction costs; (iv) pay a disposition payment under the Disposition Agreement, dated October 30, 2019, to its Manager; and (v) repurchase a portion of its  i 2.00% Convertible Senior Notes.
During the quarter ended September 30, 2020, the Company determined that each of the criteria to be classified as held for sale under ASC 205-20, Presentation of Financial Statements — Discontinued Operations, had been met as it related to IMTT. It was additionally determined that the sale of IMTT was considered a strategic shift for the Company that had a major effect on operations. Accordingly, IMTT was classified as a discontinued operation and the IMTT segment was eliminated. All prior periods were restated to reflect these changes.
Upon completion of the IMTT Transaction on December 23, 2020, the Company recognized a book loss on sale of approximately $ i 25.0 million. The Company incurred $ i 28.5 million in transaction costs and a Disposition Payment of $ i 28.2 million to its Manager, which were included in Selling, general and administrative expenses in the consolidated statement of operations. As part of classifying IMTT as held for sale, the Company recognized an impairment of the IMTT disposal group of $ i 750.0 million, which includes a goodwill impairment of $ i 725.0 million, reported in discontinued operations for the quarter ended September 30, 2020.
During the quarter ended September 30, 2020, the Company increased its deferred tax liability by $ i 158.0 million as it became probable that IMTT would be sold in a taxable transaction. The increase represented the deferred tax expense on the difference between the Company's book and tax basis in its investment in IMTT. Subsequent to the close of the IMTT Transaction in December 2020, the Company reclassified the liability to current and reduced the tax to $ i 126.2 million. The reduction primarily reflected the tax benefit of the Disposition Payment and the final determination of the tax basis of its investment in IMTT, which increased due to higher than forecasted taxable income generated prior to completion of the IMTT Transaction, as fewer assets were placed in service for tax purposes resulting in lower bonus tax depreciation during the Company’s ownership period.

Renewable Businesses Sale
During the fourth quarter of 2018, the Company commenced a sale process involving its portfolios of  i 142 megawatts ("MW") (gross) of solar generation assets and  i 203 MW (gross) of wind generation assets. In July 2019, the Company completed the sales of its wind power generating portfolio and all but one of the assets in its solar power generating portfolio. The sale of the remaining solar facility closed during September 2019. Upon closing of the transactions involving the portfolios of operating solar and wind assets, the Company deconsolidated $ i 295.1 million of long-term debt. In July 2019, the Company also completed the sale of its majority interest in a renewable power development business. The Company may be entitled to a deferred purchase price from the sale of its interest in the renewable power development business based on the sale of certain projects by the purchaser in the future.
The aggregate gross proceeds to the Company from the above sales were $ i 275.2 million, or $ i 223.8 million net of taxes and transaction related expenses. Upon closing of the transactions, the Company recorded a pre-tax gain of $ i 81.7 million excluding any transaction costs. The Company incurred $ i 9.7 million in professional fees in relation to these transactions, which is included in Selling, general and administrative expenses in the consolidated statement of operations. In 2019, the Company recorded approximately $ i 41.7 million in current tax expense primarily related to the gain on sale.
The combination of the disposal of Bayonne Energy Center in 2018 and the commencement of the sale process of substantially all of its portfolio of solar and wind facilities represented a strategic shift for the Company which will have a major effect on operations. Accordingly, beginning in the fourth quarter of 2018, these businesses were classified as discontinued operations and the Contracted Power segment was eliminated. There was no write-down of the carrying amount of the solar and wind facility assets as a result of this change in classification. The assets and liabilities of the solar and wind facilities have been classified as held for sale in the consolidated balance sheets up until the date those assets were disposed.
During the first quarter of 2019, the Company also commenced the sale of its majority interest in its renewable power development business that was reported as part of the Company’s Corporate and Other segment in the fourth quarter of 2018. Accordingly, beginning in the first quarter of 2019, the results of this business were classified as discontinued operations and the assets and liabilities of this business were classified as held for sale in the consolidated balance sheets through the date of sale. The Company did not restate the prior period related to the commencement of the sale process involving its majority interest in a renewable power development business as the disposition was insignificant. A remaining relationship with a third-party developer of renewable power facilities had been reported as a component of Corporate and Other through the expiration of the relationship in July 2019.

 i 2.00% Convertible Senior Notes due October 2023 ( i 2.00% Convertible Senior Notes)
In October 2016, the Company completed an underwritten public offering of a  i seven year, $ i 402.5 million aggregate principal amount of  i 2.00% Convertible Senior Notes. The Notes are convertible, at the holder’s option, only upon satisfaction of one or more conditions set forth in the indenture governing the Notes. Upon conversion, the Company will pay or deliver, as the case may be, cash, common units of the Company, or a combination thereof, at the Company’s election.
The $ i 402.5 million of  i 2.00% Convertible Senior Notes had an initial value of the principal amount recorded as a liability of $ i 375.8 million, using an effective interest rate of  i 3.1%. The remaining $ i 26.7 million of principal amount was allocated to the conversion feature and recorded in Common Units Paid in Capital. This amount represents a discount to the debt to be amortized through interest expense using the effective interest method through maturity. The Company also recorded $ i 11.2 million in debt financing costs from the issuance of the  i 2.00% Convertible Senior Notes, of which $ i 744,000 was recorded as equity issuance costs as a component of Unitholders’ Equity. On December 31, 2020, the outstanding balance of the liability component of the  i 2.00% Convertible Senior Notes was $ i 391.3 million with a fair value of approximately $ i 390.0 million.
On January 1, 2021, the Company adopted ASU 2020-06 under the modified retrospective method. ASU 2020-06 removes the accounting for cash conversion feature of the Notes such that the Notes would only be classified as a liability. The

During 2021, the Company repurchased $ i 395.7 million in aggregate principal amount of the  i 2.00% Convertible Senior Notes, of which $ i 358.6 million and $ i 26.9 million were repurchased in tender offers on March 16, 2021 and October 22, 2021, respectively. In connection with the repurchases, the Company incurred $ i 1.2 million of transaction costs and wrote-off $ i 3.7 million of debt financing costs recorded in Selling, general and administrative expenses and Interest Expense, respectively, in the consolidated statements of operations.
On December 31, 2021, the outstanding balance of the liability component of the  i 2.00% Convertible Senior Notes was $ i 6.8 million which approximated its fair value. The conversion rate was 162.9223 common units per $1,000 principal amount on December 31, 2021.

Hawaii Gas
On February 10, 2016, Hawaii Gas completed the refinancing of its existing $ i 80.0 million term loan and $ i 60.0 million revolving credit facility. The $ i 80.0 million term loan bears interest at a variable rate of LIBOR plus an applicable margin between  i 1.00% and  i 1.75%. The variable rate component of the debt was fixed at  i 0.99% using an interest rate swap contract, that expired upon maturity in February 2020. The revolving credit facility bears interest at a variable rate of LIBOR plus an applicable margin between  i 1.00% and  i 1.75% and is unhedged. In February 2018, Hawaii Gas exercised the second of  i two  i one-year extensions related to its $ i 80.0 million secured term loan facility and its $ i 60.0 million revolving credit facility extending their respective maturities to February 2023. During the quarter ended June 30, 2021, Hawaii Gas extended the maturity on its term loan and revolving credit facility from February 2023 to February 2024. The $ i  i 60.0 /  million revolving credit facility was undrawn on December 31, 2021 and 2020.
On December 31, 2020, Hawaii Gas also had $ i 100.0 million of fixed rate senior notes outstanding that had a fair value of approximately $ i 105.0 million. On April 19, 2021, Hawaii Gas fully repaid all of its $ i 100.0 million senior secured notes outstanding and incurred a $ i 4.7 million 'make-whole' payment and wrote-off $ i 154,000 of debt financing costs both recorded in Interest Expense in the consolidated statement of operations.

Solar Facilities
In July 2016, the solar facilities in Hawaii entered into a  i ten year, $ i 18.0 million amortizing term loan facility. The interest rate on this term loan facility floats at LIBOR plus  i 2.00%. The interest rate was fixed at  i 3.38% using an interest rate swap contract through June 30, 2026. On December 31, 2021 and 2020, the outstanding balance on the term loan was $ i 12.7 million and $ i 13.8 million, respectively.
10.  i Derivative Instruments and Hedging Activities
From time to time, the Company enters into interest rate agreements to minimize potential variations in cash flows resulting from fluctuations in interest rates and their impact on its variable-rate debt. The Company does not enter into derivative instruments for any purpose other than economic interest rate hedging. That is, the Company does not speculate using derivative instruments. In addition, Hawaii Gas enters into commodity hedge contracts to mitigate the impact of fluctuations in LPG prices on its cash flows.
By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. Conversely, when the fair value of a derivative contract is negative, the Company owes the counterparty and, therefore, it does not pose a credit risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with creditworthy counterparties.
Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates. The market risk associated with interest rates is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

10. Derivative Instruments and Hedging Activities  – (continued)
Interest Rate Contracts
The Company has in place variable-rate debt. Interest rate swaps change the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps currently in place, the Company receives variable interest rate payments and makes fixed rate interest payments, thereby creating the equivalent of fixed-rate debt for the portion of the debt that is swapped.
The Company does not use hedge accounting. All movements in the fair value of the interest rate derivatives are recorded directly through earnings.
Hawaii Gas had an $ i 80.0 million interest rate swap that fully hedged its term loan. The interest rate swap expired in February 2020. To finance its solar facilities, the Company entered into a  i ten year, amortizing term loan facility that floats at LIBOR plus  i 2.00%. This term loan facility is fully hedged with an amortizing interest rate swap contract that is scheduled to amortize concurrently with the term loan and fixes the interest rate at  i 3.38%.
Commodity Price Hedges
The risks associated with fluctuations in the prices that Hawaii Gas pays for LPG is principally a result of market forces reflecting changes in supply and demand. Hawaii Gas’ gross margin (revenue less cost of product sales excluding depreciation and amortization) is sensitive to changes in LPG supply costs and Hawaii Gas may not always be able to pass through cost increases fully or on a timely basis, particularly when product costs rise rapidly. To reduce its exposure to the volatility of the business’ LPG wholesale market price, Hawaii Gas has used and expects to continue to use over-the-counter commodity derivative instruments. Hawaii Gas does not use commodity derivative instruments for speculative or trading purposes. Over-the-counter derivative instruments used by Hawaii Gas to hedge a portion of forecasted purchases of LPG are generally settled at expiration of the contract. On December 31, 2021, Hawaii Gas had  i 60.7 million gallons of LPG hedged through May 2024.
Financial Statement Location Disclosure for Derivative Instruments
The Company measures derivative instruments at fair value using the income approach which discounts the future net cash settlements expected under the derivative contracts to a present value. These valuations use primarily observable (level 2) inputs, including contractual terms, interest rates, and yield curves observable at commonly quoted intervals.

12.  i Revenue Recognition
The Company's business comprises: (i) Hawaii Gas, Hawaii’s only government-franchised gas utility and an unregulated LPG distribution business providing gas and related services to industrial, commercial, residential, and governmental customers; (ii) controlling interests in  i two solar facilities on Oahu, and (iii) smaller projects collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii.
Revenue from Hawaii Gas is generated from the distribution and sales of synthetic natural gas ("SNG"), LPG, liquefied natural gas ("LNG"), and renewable natural gas ("RNG"). Revenue is primarily a function of the amount of product consumed by customers and the price per British Thermal Unit or gallon charged to customers. Revenue levels, without organic growth, will generally track global commodity prices, namely petroleum and natural gas, as its products are derived from these commodities.
Revenue from Hawaii Gas is recorded in product revenue. Hawaii Gas recognizes revenue when products are delivered. Sales of gas to customers are billed on a monthly-cycle basis. Earned but unbilled revenue is accrued and included in accounts receivable and revenue. This is based on the amount of gas that has been delivered but not billed to customers from the latest meter reading or billed delivery date to the end of an accounting period. The related costs are charged to expense.
The renewables projects in Hawaii sell substantially all of the electricity generated at a fixed price to primarily electric utility customers pursuant to long-term power purchase agreements ("PPAs") of  i 20 years. The PPAs are accounted for as operating leases and have no minimum lease payments. Lease income is recorded within product revenue when the electricity is delivered.

Under the MSA, subject to the oversight and supervision of the Company’s Board, the Manager is responsible for and oversees the management of the Company’s business. In addition, the Manager has the right to appoint the Chairman of the Board, subject to minimum equity ownership, and to assign, or second, to the Company, two of its employees to serve as chief executive officer and chief financial officer of the Company and seconds or makes other personnel available as required.
In accordance with the MSA, the Manager is entitled to a monthly base management fee based primarily on the Company’s market capitalization, and potentially a quarterly performance fee based on total unitholder returns relative to a U.S. utilities index. Currently, the Manager has elected to reinvest future base management fees and performance fees, if any, in additional units. In 2021, 2020, and 2019, the Company incurred base management fees of $ i 21.9 million, $ i 21.1 million, and $ i 32.1 million, respectively. The Company did  i  i  i no /  / t incur any performance fees in 2021, 2020, and 2019.
Effective November 1, 2018, the Manager waived two portions of the base management fee to which it was entitled under the terms of the MSA. In effect, the waivers cap the base management fee at  i 1% of the Company’s equity market capitalization less any cash balances at the holding company. The waiver applies only to the calculation of the base management fees and not to the remainder of the MSA. The Manager reserves the right to revoke the waivers and revert to the prior terms of the MSA, subject to providing the Company with not less than a  i one year notice. A revocation of the waiver would not trigger a recapture of previously waived fees. As part of the Disposition Agreement entered into between the Company and its Manager, discussed below, the Manager has agreed not to revoke the waiver during the term of the Disposition Agreement. The amendment to the Disposition Agreement, described below, provides for the payment of the waived fees upon the consummation of the Merger.
Disposition Agreement
To facilitate the Company’s pursuit of strategic alternatives, the Company announced that it has entered into a Disposition Agreement with its Manager on October 30, 2019 (see Exhibit 10.3 of this Form 10-K). Outside of the Disposition Agreement, the Company has limited ability to terminate the Management Services Agreement. The Disposition Agreement provides for the termination of the Company’s external management relationship with its Manager as to any businesses, or substantial portions thereof, that are sold (including if the Company itself is sold). In connection therewith, the Company will make a payment to its Manager of approximately  i 2.9% to  i 6.1% of the net proceeds generated in the event of such sales, subject to a minimum amount of payments for all sales in the aggregate in the event of a Qualifying Termination Event ("QTE") of (i) $ i 50.0 million plus (ii)  i 1.5% multiplied by proceeds in excess of $ i 500.0 million in the aggregate. A ‘‘QTE’’ means (i) the sale of the Company or (ii) a transaction or series of transactions resulting in a third party or parties acquiring all the assets of the Company. The Disposition Agreement provides that the Management Services Agreement will terminate upon the occurrence of a QTE or upon mutual agreement of the parties. If the Management Services Agreement has not been terminated prior to the sixth anniversary of the Disposition Agreement, its Manager and its independent directors will engage in reasonable, good faith discussions regarding a potential internalization or other framework for a termination of the MSA.

The Disposition Agreement provides that if a QTE occurs on or prior to January 1, 2022 (subject to extension under certain circumstances for up to  i six months thereafter), then the Company will pay its Manager an additional payment of $ i 25.0 million. The Disposition Agreement further provides that its Manager will receive a make-whole payment following a QTE, to the extent that the aggregate management fees paid to its Manager through the date of the QTE were less than (i) $ i 20.0 million per year for the  i two years following the date of the Disposition Agreement and (ii) $ i 10.0 million per year for any period thereafter. In addition, following a QTE, the Manager will be paid in cash all accrued and unpaid management fees, including fees of $ i 8.5 million waived in accordance with the Limited Waiver, which waived fees would have been payable through October 31, 2019. The Manager has agreed not to exercise its right to retract the Limited Waiver for periods after October 31, 2019 and prior to the termination of the Disposition Agreement. The Disposition Agreement will terminate on the earlier to occur of (i) the termination of the Management Services Agreement and (ii) the sixth anniversary of the Disposition Agreement, subject to extension under certain circumstances if a transaction is pending.
In connection with the IMTT Transaction and pursuant to the Disposition Agreement, as amended by the Amendment noted above, the Company deposited a disposition payment of $ i 28.2 million to its Manager in an escrow account in December 2020 and subsequently released the payment from escrow in March 2021.
In connection with the execution of the Merger, and in order to provide AMF Parent with the fixed amount of the Disposition Payment (as defined in the Disposition Agreement) payable to the Manager with respect to the Merger, on June 14, 2021, the Company and the Manager entered into an amendment (the "Amendment") to the Disposition Agreement. The Amendment provides that the Disposition Payment payable to the Manager with respect to the Merger will be $ i 56.7 million (which amount includes the waived fees pursuant to the Manager's limited waiver described above). These amounts were calculated in accordance with the Disposition Agreement dated as of October 30, 2019 (assuming a March 31, 2022 closing date), do not include the $ i 25.0 million additional payment to the Manager if the final sale of the Company occurs on or prior to July 1, 2022. The Amendment also provides that the Disposition Payments with respect to the Merger will be paid concurrently with the relevant transaction closing, and that the Company’s MSA with the Manager will terminate concurrent with the closing of the Merger and payment of all amounts payable to the Manager under the Disposition Agreement.
In connection with the AA Transaction and pursuant to the Disposition Agreement, the Company paid the Manager $ i 228.6 million in September 2021 concurrent with the closing of the transaction.

In assessing the need for a valuation allowance, the Company considers whether it is more likely than not that some portion of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. In 2021, there was  i no valuation allowance.
On December 31, 2021, the Company had $ i 38.5 million in noncurrent deferred tax liabilities from continuing operations. A significant portion of the Company’s deferred tax liabilities relates to tax basis temporary differences of both intangible assets and property and equipment. The Company records the acquisitions of consolidated businesses under the purchase method of accounting and accordingly recognizes a significant increase to the value of the property and equipment and to intangible assets. For tax purposes, the Company may assume the existing tax basis of the acquired businesses, in which case the Company records a deferred tax liability to reflect the increase in the purchase accounting basis of the assets acquired over the carryover income tax basis. This liability will reduce in future periods as these temporary differences reverse.
In 2021 and 2019, the Company recorded a total tax benefit of $ i 7.8 million and $ i 11.6 million, respectively, from continuing operations. In 2020, the Company recorded a total tax provision of $ i 4.2 million from continuing operations.  i These amounts are different from the amounts computed by applying the U.S. federal income tax rate for the period to pre-tax income as a result of the following ($ in thousands):

15.  i Employee Benefit Plans
401(k) Savings Plan
Hawaii Gas, IMTT and Atlantic Aviation each have a defined contribution plan under Section 401(k) of the Internal Revenue Code, allowing eligible employees to contribute a percentage of their annual compensation up to an annual amount as set by the IRS.
The employer contribution of eligible compensation to these plans ranges from  i 0% to  i 6% for Hawaii Gas and  i 0% to  i 7% for discontinued operations. Employer contributions for Hawaii Gas were $ i 927,000, $ i 907,000 and $ i 910,000 in 2021, 2020 and 2019, respectively. Employer contributions for discontinued operations were $ i 1.7 million, $ i 4.7 million, and $ i 4.5 million in 2021, 2020, and 2019, respectively. For additional information, see Note 4, "Discontinued Operations and Dispositions", for further discussions.
Hawaii Gas Union Pension Plan
Hawaii Gas has a defined benefit pension plan for Classified Employees of GASCO, Inc. ("HG DB Plan") that accrues benefits pursuant to the terms of a collective-bargaining agreement. The plan was frozen to new participants in 2008 in connection with an agreement to increase participant benefits over a  i three year period after which there will be no further increases to the flat rate as described herein. The HG DB Plan is non-contributory and covers all bargaining unit employees who have met certain service and age requirements. The benefits are based on a flat rate per year of service through the date of employment termination or retirement. Future contributions will be made to meet ERISA funding requirements. The HG DB Plan’s trustee handles the plan assets and, as an investment manager, invests them in a diversified portfolio of primarily equity and fixed-income securities.
IMTT DB Plan
Except for a plan covering certain employees covered by a collective-bargaining agreement at IMTT-Illinois (see below), substantially all employees of IMTT are eligible to participate in a defined benefit pension plan ("IMTT DB Plan"). Benefits under the IMTT DB Plan are based on years of service and the employees’ highest average compensation for a consecutive  i five year period. IMTT’s contributions to the plan are based on the recommendations of its consulting actuary.
On January 1, 2017, the IMTT DB Plan was frozen to new participants, except for the union employees of Bayonne, for whom it was subsequently frozen on January 1, 2018. On December 23, 2020, the IMTT DB Plan was sold in connection with the IMTT Transaction and was assumed by the buyer. See Note 4, "Discontinued Operations and Dispositions”, for further discussions.
Other Plan Benefits
Hawaii Gas, IMTT and Atlantic Aviation have other insignificant plans that are comprised of the following. These plans are shown below collectively as “Other Plan Benefits”.
Hawaii Gas
Hawaii Gas has a postretirement plan. The GASCO, Inc. Hourly Postretirement Medical and Life Insurance Plan (the "PMLI Plan") covers all bargaining unit participants who were employed by Hawaii Gas on April 30, 1999 and who retire after the attainment of age  i 62 with  i 15 years of service. Under the provisions of the PMLI Plan, Hawaii Gas pays for medical premiums of the retirees and spouses through the age of  i 64. After age  i 64, Hawaii Gas pays for medical premiums up to a maximum of $ i 150 per month. The retirees are also provided $ i 1,000 of life insurance benefits.
Hawaii Gas also has a retiree life insurance program for certain nonunion retirees. This plan is closed to future participants.

15. Employee Benefit Plans  – (continued)
IMTT
IMTT is the sponsor of a defined benefit plan covering union employees at IMTT-Illinois ("IMTT-Illinois Union Plan"). Monthly benefits under this plan are computed based on a benefit rate in effect at the date of the participant’s termination multiplied by the number of years of service. IMTT’s contributions to the plan are based on the recommendations of its consulting actuary. On January 1, 2018, the IMTT-Illinois Union Plan was frozen to new participants.
IMTT provides post-retirement life insurance (coverage equal to  i 25% of final year compensation not to exceed $ i 25,000) and health benefits (coverage for early retirees at least  i 62 years old on early retirement to age  i 65, reimbursement of Medicare premiums for the Bayonne terminal employees and some smaller health benefits no longer offered) to retired employees.
On December 23, 2020, the IMTT-Illinois Union Plan and the post-retirement life insurance plan was sold in connection with the IMTT Transaction and was assumed by the buyer. See Note 4, "Discontinued Operations and Dispositions”, for further discussions.
Atlantic Aviation
Atlantic Aviation sponsors a retiree medical and life insurance plan available to certain employees. Currently, the plan is funded as required to pay benefits and the plan has no assets. The Company accounts for postretirement healthcare and life insurance benefits in accordance with ASC 715, Compensation — Retirement Benefits, which requires the accrual of the cost of providing postretirement benefits during the active service period of the employee.
On September 23, 2021, the Atlantic Aviation retiree medical and life insurance plan was sold in connection with the AA Transaction and was assumed by the buyer. See Note 4, "Discontinued Operations and Dispositions", for further discussions.

For the HG DB Plan, both accumulated and projected benefit obligations were $ i  i 56.6 /  million and were in excess of the fair value of plan assets of $ i  i 55.0 /  million on December 31, 2021. This compares with aggregate accumulated and projected benefit obligations of $ i  i 58.7 /  million, which were also in excess of the aggregate fair value of plan assets of $ i  i 56.0 /  million on December 31, 2020. The remaining postretirement plans resulted in accumulated postretirement benefit obligations of $ i 2.8 million on December 31, 2021 and $ i 3.2 million on December 31, 2020. Fair value of plan assets on these plans were  i  i zero /  for both periods.
Actuarial gains in the changes in benefit obligations for 2021 resulted primarily due to increase in discount rate. For 2020 actuarial losses resulted primarily due to decrease in discount rate (see assumptions used in table below).
In 2021 and 2020, there were  i  i no /  contributions made to the HG DB Plan. As of December 31, 2021, Hawaii Gas is not expected to make any cash contribution to the HG DB Plan through 2031.

ITEM 9A. CONTROLS AND PROCEDURES
(a) Management’s Evaluation of Disclosure Controls and Procedures
Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Form 10-K, have concluded that, based on such evaluation, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
(b) Management’s Annual Report on Internal Control over Financial Reporting
Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2021. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers 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 U.S. generally accepted accounting principles.
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 the preparation of financial statements in accordance with U.S. GAAP, 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.
All internal control systems, no matter how well designed, have inherent limitations. Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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 the degree of compliance with the policies, or procedures may deteriorate. Accordingly, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
Management used the framework set forth in the report entitled ‘‘Internal Control-Integrated Framework (2013)’’ published by the Committee of Sponsoring Organizations of the Treadway Commission (referred to as COSO) to evaluate the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. As a result of its evaluation, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2021 based on those criteria.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 has been audited by KPMG LLP, the Company’s independent registered public accounting firm, as stated in their report appearing on page 93, which expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021.

Macquarie Infrastructure Holdings, LLC:
Opinion on Internal Control Over Financial Reporting
We have audited Macquarie Infrastructure Holdings, LLC and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income (loss), unitholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2021, and the related notes (collectively, the consolidated financial statements), and our report dated February 22, 2022 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
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 Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. 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 of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed 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 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 Code of Business Conduct applies to all of our directors, officers, and employees as well as all directors, officers, and employees of our Manager involved in the management of the Company and its businesses. Our Code of Business Conduct is posted on the Governance page of our website, www.macquarie.com/mic. We will post any amendment to the Code of Business Conduct, and any waivers that are required to be disclosed by the rules of either the SEC or the NYSE, on our website.
BOARD LEADERSHIP STRUCTURE
Our current board leadership structure is composed of a chairman, who is not a member of management but is elected by our Manager, and a lead independent director in accordance with our corporate governance guidelines. Currently, Norman H. Brown, Jr. serves as the lead independent director. Our lead independent director presides at, and determines frequency and timing of, executive sessions of our independent directors, which occur at least quarterly and more often as our independent directors deem appropriate. Our lead independent director also consults with our chairman on agendas and meeting schedules, serves as liaison between our chairman and our independent directors, serves as liaison for shareholders who request direct communication with our board, and performs such other duties as may be assigned by our board. Each of our board committees, except the Executive Committee, are chaired by and are wholly composed of independent directors. We believe that this leadership structure is appropriate at this time given our externally-managed corporate structure and the benefits that this structure provides to our shareholders by combining our Manager’s knowledge of infrastructure businesses with independent oversight of our Manager’s activities.
Our board’s chairman is elected by our Manager as the sole holder of our special units. The chairman presides over meetings of our board and meetings of shareholders, prepares the agenda for meetings of our board in consultation with our lead independent director and with input from our other directors, coordinates communication among directors and performs
96

TABLE OF CONTENTS
such other duties as may be assigned by our board. Because our chairman is elected by our Manager, but is not a member of our management team, he is able to draw upon their extensive knowledge of infrastructure businesses and provide a strategic perspective on our business activities. The following biography highlights the qualifications and experience of Mr. Stanley, our chairman.
OUR BOARD’S ROLE IN RISK OVERSIGHT
Our board is responsible for overseeing our Company’s management of various risks. It discharges this responsibility directly and through its committees.
Our board and its committees regularly review material enterprise, strategic, operational, legal, safety and compliance risks with senior management of the Company and our Manager. Our board is responsible for endorsing the Company’s risk management framework, including key policies and procedures, and approving of any changes to the framework or any key risk policies and procedures, monitoring compliance with the risk management framework and delegating authority to management, where appropriate. On a regular basis, our board is presented with safety reports and assessments and risk and compliance reports from management and compliance personnel directly responsible for the identification, evaluation and monitoring of risks within the business.
As part of the monitoring process, our board or the appropriate committee is provided with the following information at scheduled board meetings: any proposed changes to the risk management framework; key policies and procedures or reporting arrangement for its approval; reports on exposures, non-compliance with key policies and general effectiveness of risk management system, as appropriate; results of independent reviews or audits of the control environment; and the relevant management information. While our board oversees risk management, the Company’s management is responsible for managing risk.
Our board has delegated responsibility for oversight of certain specific risks to our audit committee. Our audit committee is responsible for an annual review of our Company’s policies with respect to risk assessment and risk management. Our audit committee has primary responsibility for overseeing risk policies and processes relating to the financial statements and financial reporting, as well as overseeing the Company’s major financial risk exposures, management of our legal, regulatory and cybersecurity risks and our compliance with applicable laws and regulations. Our audit committee is primarily responsible for assessing the adequacy of our internal control framework, including accounting and operational risk management controls based on information provided or obtained from management. Our audit committee is also responsible for reviewing and monitoring our Code of Business Conduct to guard against significant conflicts of interest and dishonest, unethical or illegal activities. Our audit committee periodically reviews the performance of the Company’s accounting and financial personnel and reviews material litigation and regulatory proceedings and other matters relating to potentially significant corporate liability with the Company’s general counsel.
BOARD COMPOSITION AND INDEPENDENCE
Our board consists of eight directors, seven of whom were elected by shareholders of the Company at the last Annual Meeting. The remaining director, our chairman, currently Mr. Stanley, is elected by our Manager as the sole holder of our special unit. Except for Mr. Stanley, all directors’ terms expire at the Annual Meeting.
The majority of our board comprises independent directors. In accordance with the listing standards of the NYSE, to be considered independent, our board must affirmatively determine that a director has no material relationship with the Company, either directly or as a partner, unitholder or officer of an organization that has a relationship with the Company, and that the director meets other NYSE independence standards. Ms. Sananikone was previously chairperson of Smarte Carte and a non-executive director of Icon Parking, Moto Hospitality Services and Air-Serv Holdings, which are companies that are or were owned by investor consortiums but managed by affiliates of our Manager. In each case, Ms. Sananikone was the appointee of non-Macquarie investors of the consortium investment vehicle. Our board has determined that this relationship is immaterial to a determination of independence.
Accordingly, our board has determined that Mmes. Brock, Jelescu-Dreyfus and Sananikone and Messrs. Brown, Kirk and Lentz are independent under NYSE standards and Mr. Stanley and Mr. Frost are not independent under the NYSE standards.
BOARD MEETINGS AND COMMITTEES; ANNUAL MEETING ATTENDANCE
Our board met 20 times in total in 2021. All directors attended approximately 92% of the combined board and committee meetings on which they served in 2021. In addition, it is the policy of our board that our directors are expected to use reasonable efforts to attend the Annual Meeting of Shareholders. All directors then in office participated in our 2021 Annual Meeting of Shareholders.

Mr. O’Neil served as MAM's Head of Real Estate in the U.S. (2016 – 2018), Head of Brazil (2015 – 2016) and Head of Mexico (2010 – 2014).

Before joining Macquarie, Mr. O’Neil was employed by KPMG Australia where he advised clients on all aspects of corporate tax.
Jay Davis, 62, joined the Company in May 2005 and has primary responsibility for investor relations on behalf of the Company. In addition to his investor relations responsibilities, Mr. Davis is a Division Director at Macquarie.
Prior to joining Macquarie, Mr. Davis spent 22 years with the MONY Group, a provider of insurance and investment products and services, where he last served as senior vice president, investor relations.

He has over 30 years of experience as a corporate lawyer for public and private companies and fund sponsors, advising on matters including fund formation and management, M&A transactions, securities law compliance, and corporate governance.

ITEM 11. EXECUTIVE COMPENSATION
We have a Management Services Agreement with our Manager pursuant to which they are responsible for and oversee the management of our business in exchange for certain fees. Our ultimate parent company does not have any employees. The Macquarie employees who serve as our seconded executive officers have been assigned, or seconded, to us by our Manager on a full-time basis.
We do not pay any compensation to our seconded executive officers and therefore are not providing a description of executive officer compensation, Compensation Discussion and Analysis or the pay ratio between employees and our principal executive officer. Our Manager is responsible for the expenses related to all services performed for the Company, including all the compensation of our seconded executive officers. Our Company pays management fees to our Manager in accordance with the Management Services Agreement. Base management fees earned by our Manager are based on the market capitalization of our Company less cash on hand at the holding company. Performance fees, if any, are based on ongoing out-performance of the Company over a utilities benchmark. These fees are set forth below under “Certain Relationships and Related Party Transactions”.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
Mmes. Brock, Jelescu-Dreyfus and Sananikone and Messrs. Brown, Kirk and Lentz are members of our compensation committee. None of the members of our compensation committee is, or has been, an employee of the Company. During 2021, no member of our compensation committee had any relationship with the Company requiring disclosure under Item 404 of Regulation S-K. None of the Company’s executive officers or members of our Company’s board has served as a member of a compensation committee (or if no committee performs that function, our board of directors) of any other entity that has an executive officer serving as a member of our Company’s board or compensation committee.

COMPENSATION ASSESSMENT
The compensation committee believes that our Manager’s compensation policies and practices with respect to the Company’s executives do not encourage excessive risk-taking and are not reasonably likely to have a material adverse effect on the Company. In reaching this conclusion, our compensation committee considered its role in establishing and monitoring performance targets, that the elements of compensation are balanced among current cash payments, deferred cash and equity awards, the time vesting requirements of Macquarie’s profit share program which provide alignment between the executives’ interests and those of shareholders, the fact that compensation is based on financial performance and other measures including leadership and upholding Macquarie’s values, and the oversight by our board of the executives’ actions. Our compensation committee also oversees the setting of performance objectives for and the award of restricted stock units and/or performance
101

TABLE OF CONTENTS
stock units to certain senior employees of our operating companies. Our compensation committee believes that the Company’s policies and practices with respect to setting performance targets for the senior employees of the operating companies, such as time and performance based vesting requirements, do not encourage excessive risk-taking and provide alignment between the interests of these individuals with those of unitholders.
DIRECTOR FEES
Our independent directors each receive annual cash retainers, payable in equal quarterly installments, of $65,000 for service on our board, for service as committee chairman and for service as the lead independent director, as well as cash compensation for attendance at committee meetings. Directors (including non-independent directors and the chairman elected by our Manager) are reimbursed for reasonable out-of-pocket expenses incurred in attending meetings of our board or committees and for any expenses reasonably incurred in their capacity as directors. The Company also reimburses directors for all reasonable and authorized business expenses in accordance with the policies of the Company as in effect from time to time.
Each member of the Company’s various standing committees also receives the following compensation related to service on these committees:
• for attending a committee meeting in person (if any): $3,000 for each meeting of the audit committee; $1,500 for each meeting of the nominating and governance committee; and $1,500 for each meeting of the compensation committee; and,
• for attending a telephonic committee meeting (if any): $1,500 for each meeting of the audit committee; $1,000 for each meeting of the nominating and governance committee; and $1,000 for each meeting of the compensation committee.
The lead independent director receives an annual cash retainer of $10,000 and the chairperson of each of the audit committee, nominating and governance committee and compensation committee also receive an annual cash retainer of $15,000, $2,000 and $2,000, respectively, payable in equal quarterly installments.
2014 INDEPENDENT DIRECTORS' EQUITY PLAN ("2014 PLAN")
The only type of award that may be granted under the 2014 Plan is an award of director share units. A director share unit is an unsecured promise to transfer one common unit of the Company in the future on the settlement date, subject to satisfaction of the terms and conditions under the 2014 Plan and the applicable award agreement.
Under the 2014 Plan, there is no formula to determine the size of awards and the compensation committee has the authority to determine the size of all awards and terms and conditions thereof, subject to the provisions of the 2014 Plan, including the limits on the number of director share units that may be granted annually and in the aggregate. Generally, director share units granted at each annual meeting of shareholders will vest (assuming continued service of the director) on the day immediately preceding the next annual meeting of shareholders held following the date of grant. The number of director share units available for issuance under the 2014 Plan is 2,481,999 units as of February 18, 2022. The aggregate grant date fair value of awards granted to an independent director during any single fiscal year (excluding awards made at the election of the independent director in lieu of all or a portion of annual and committee cash retainers) may not exceed $350,000.
If a director’s service on our board terminates by reason of death or disability or in the event of a business combination of the Company during the director’s service, the director share units will vest immediately.
We credit director share units to a bookkeeping account. No interest or dividends accrue or are credited to any director share units or the director’s account. As soon as practical following vesting, we will settle director share units by delivering to the director the equivalent whole number of shares. Director share units cannot be settled in cash or any other kind of consideration. Prior to settlement, directors do not have the rights of a shareholder in any share corresponding to the director share units.
DIRECTOR COMPENSATION FISCAL YEAR 2021
The following table sets forth the compensation payable by us to our independent directors for service during the fiscal year ended December 31, 2021. We do not compensate our chairman or chief executive officer for their service on our board. The table reflects the equity grants by the Company to directors that fully vested on September 23, 2021 as a result of the AA Transaction, which constituted a change in control as defined in the 2014 Plan.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS
SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth information regarding the beneficial ownership of common stock by each person who is known to us to be the beneficial owner of more than five percent of the outstanding units on December 31, 2021, and each of our directors and seconded executive officers and our directors and executive officers as a group as of December 31, 2021, based on 88,343,762 common units issued and outstanding. All holders of common units are entitled to one vote per unit on all matters submitted to a vote of holders of common units. The voting rights attached to units held by our directors, executive officers or major shareholders do not differ from those that attach to units held by any other holder. Under Rule 13d-3 of the Exchange Act, “beneficial ownership” includes units for which the individual, directly or indirectly, has voting power, meaning the power to control voting decisions, or investment power, meaning the power to cause the sale of the units, whether or not the units are held for the individual’s benefit.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS AND DIRECTOR INDEPENDENCE
CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
RELATED PARTY TRANSACTIONS POLICIES
Our board recognizes that related party transactions present a heightened risk of conflicts of interest and therefore has adopted internal policies to be followed in connection with related party transactions.
Our audit committee is required to approve all related party transactions, including transactions in which the Company is a participant, the amount involved exceeds $120,000 in any fiscal year in which a related party has a material interest. Related
104

TABLE OF CONTENTS
parties include directors, executive officers, holders of 5% of the Company’s voting units and Macquarie or its subsidiaries (or any immediate family members of the foregoing).
In considering any related party transaction, our audit committee considers all relevant factors including, among others, the benefits to the Company, the related party’s interest in the transaction, whether the terms are at arm’s length, any potential impact on director independence and the opportunity costs of other sources for comparable products or services.
Our board has also adopted a written policy pursuant to which it has pre-approved certain types of transactions with related parties assuming certain conditions are met. The pre-approval policy permits foreign exchange, depository and similar transactions (such as the establishment of bank, brokerage and custodial accounts) for which the terms provided by the related party are equal or more favorable to us than those quoted by unaffiliated counterparties. All pre-approved transactions are included as a standing item in reports to our board and audit committee at regular meetings.
OUR RELATIONSHIP WITH MACQUARIE
Macquarie Infrastructure Management (USA) Inc., our Manager, is a part of Macquarie. From time to time, we have entered into, and in the future we may enter into, transactions and relationships involving Macquarie, its affiliates, or vehicles managed by Macquarie. As discussed above, our audit committee is required to approve all related party transactions, including those involving Macquarie, except for those pre-approved by our board. Our chairman and chief executive officer also served as directors without compensation for affiliates of our Manager within Macquarie.
CONTRACTUAL ARRANGEMENTS WITH OUR MANAGER
Our Manager’s Investment in the Company and Registration Rights
As of February 18, 2021, our Manager held 14,791,746 units of our Company. Pursuant to the terms of the Fourth Amended and Restated Management Services Agreement ("Management Services Agreement"), our Manager may sell these units at any time. Under the Management Services Agreement, our Manager, at its option, may reinvest base management fees and performance fees, if any, in units of our Company. Our Manager’s holdings on February 18, 2021 represented 16.73% of our outstanding common units.
We entered into a registration rights agreement with our Manager under which we agreed to file a shelf registration statement under the Securities Act relating to the resale of units owned by our Manager. In addition, our Manager may also require us to include its units in future registered offerings that we conduct, subject to cutback at the option of the underwriters of any such offering.
Since January 1, 2021, we paid the Manager cash dividends and/or distributions on units held for the following periods:

Management Services Agreement
Management and Fees. We are a party to a Management Services Agreement subject to the oversight and supervision of our board. Our Manager is responsible for and oversees the management of our operating businesses. In addition, our Manager has the right to elect the chairman of our board of our Company, subject to minimum equity ownership, and to assign, or second, to our Company, two of its employees to serve as chief executive officer and chief financial officer of the Company and seconds or makes other personnel available as required. The board member elected by our Manager does not receive any compensation (other than out-of-pocket expenses) and does not have any special voting rights.
In accordance with the Management Services Agreement, our Manager is entitled to a monthly base management fee based primarily on our Company’s market capitalization less cash balances at our holding company, and potentially a quarterly performance fee based on the total shareholder return relative to a U.S. utilities index. Currently, our Manager has elected to reinvest the base management fees and performance fees, if any, in additional units. For the year ended December 31, 2021, we incurred base management fees of $21.9 million. We did not incur a performance fee for the year ended December 31, 2021.
105

TABLE OF CONTENTS
Effective November 1, 2018, our Manager waived two portions of the base management fee to which it was entitled under the terms of the Management Services Agreement (the “Limited Waiver”). In effect, the waivers cap the base management fee at 1% of our equity market capitalization less any cash balances at our holding company. The waiver applies only to the calculation of the base management fees and not to the remainder of the Management Services Agreement. Our Manager reserves the right to revoke the waivers and revert to the prior terms of the Management Services Agreement, subject to providing the Company with not less than a one-year notice. A revocation of the waiver would not trigger a recapture of previously waived fees.
Disposition Agreement
To facilitate our Company’s pursuit of strategic alternatives, our Company announced that it entered into a Disposition Agreement (“Disposition Agreement”) with our Manager on October 30, 2019 (see Exhibit 10.3 of this Form 10-K). Outside of the Disposition Agreement, our Company has limited ability to terminate the Management Services Agreement. The Disposition Agreement provides for the termination of our Company’s external management relationship with our Manager as to any businesses, or substantial portions thereof, that are sold (including if the Company itself is sold). In connection therewith, we will make a payment to our Manager of approximately 2.9% to 6.1% of the net proceeds generated in the event of such sales, subject to a minimum amount of payments for all sales in the aggregate in the event of a Qualifying Termination Event (“QTE”) of (i) $50.0 million plus (ii) 1.5% multiplied by proceeds in excess of $500.0 million in the aggregate. A “QTE” means (i) the sale of the Company or (ii) a transaction or series of transactions resulting in a third party or parties acquiring all the assets of the Company. The Disposition Agreement provides that the Management Services Agreement will terminate upon the occurrence of a QTE or upon mutual agreement of the parties. If the Management Services Agreement has not been terminated prior to the sixth anniversary of the Disposition Agreement, our Manager and our independent directors will engage in reasonable, good faith discussions regarding a potential internalization or other framework for a termination of the Management Services Agreement.
The Disposition Agreement provides that if a QTE occurs on or prior to January 1, 2022 (subject to extension under certain circumstances for up to six months thereafter), then we will pay our Manager an additional payment of $25.0 million. The Disposition Agreement further provides that our Manager will receive a make-whole payment following a QTE, to the extent that the aggregate management fees paid to our Manager through the date of the QTE were less than (i) $20.0 million per year for the two years following the date of the Disposition Agreement and (ii) $10.0 million per year for any period thereafter. In addition, following a QTE, our Manager will be paid in cash all accrued and unpaid management fees, including fees of $8.5 million waived in accordance with the Limited Waiver, which waived fees would have been payable through October 31, 2019. Our Manager has agreed not to exercise its right to retract the Limited Waiver for periods after October 31, 2019 and prior to the termination of the Disposition Agreement. The Disposition Agreement will terminate on the earlier to occur of (i) the termination of the Management Services Agreement and (ii) the sixth anniversary of the Disposition Agreement, subject to extension under certain circumstances if a transaction is pending.
In connection with the IMTT Transaction and pursuant to the Disposition Agreement, the Company deposited a disposition payment of $28.2 million to its Manager in an escrow account in December 2020 and subsequently released the payment from escrow in March 2021.
In connection with the execution of the Merger, and in order to provide AMF Parent with the fixed amount of the Disposition Payment (as defined in the Disposition Agreement) payable to the Manager with respect to the Merger, on June 14, 2021, the Company and the Manager entered into an amendment (the "Amendment") to the Disposition Agreement. The Amendment provides that the Disposition Payment payable to the Manager with respect to the Merger will be $56.7 million (which amount includes the waived fees pursuant to the Manager's limited waiver described above). These amounts were calculated in accordance with the Disposition Agreement dated as of October 30, 2019 (assuming a March 31, 2022 closing date), do not include the $25.0 million additional payment to the Manager if the final sale of the Company occurs on or prior to July 1, 2022. The Amendment also provides that the Disposition Payments with respect to the Merger will be paid concurrently with the relevant transaction closing, and that the Company’s MSA with the Manager will terminate concurrent with the closing of the Merger and payment of all amounts payable to the Manager under the Disposition Agreement.
In connection with the AA Transaction and pursuant to the Disposition Agreement, the Company paid the Manager $228.6 million in September 2021 concurrent with the closing of the transaction.
The unpaid portion of the base management fees and performance fees, if any, at the end of each reporting period is included in Due to Manager-related party in the consolidated balance sheets. The following table shows the Manager’s reinvestment of its base management fees and performance fees, if any, in units:

Second quarter 20217,551 — 214,040 
First quarter 20215,552 — 176,296 
(1)The Manager elected to reinvest all of the monthly base management fees for the quarter ended December 31, 2021 in new primary units. The Company issued 217,273 units for the quarter ended December 31, 2021, including 72,323 units that were issued in January 2022 for the December 2021 monthly base management fee.
Our Manager is not entitled to any other compensation and all costs incurred by the Manager, including compensation of seconded staff, are paid by the Manager out of its base management fee. However, our Company is responsible for other direct costs including, but not limited to, expenses incurred in the administration or management of our Company and its subsidiaries, income taxes, audit and legal fees, acquisitions and dispositions, and its compliance with applicable laws and regulations. Our Manager charged the Company $5,000 in 2021 for reimbursement of out-of-pocket expenses. In 2021, our Company paid $38,000 in legal fees incurred by our Manager related to certain MIC shareholder litigation. The payment reflects a credit of $30,000 of legal fees incurred by our Manager in 2020.
Investment Priority. Under the terms of the Management Services Agreement, our Manager has exclusive responsibility for reviewing and making recommendations to our board with respect to acquisition opportunities and dispositions. If an opportunity is not originated by our Manager, our board must seek a recommendation from our Manager prior to making a decision concerning any acquisition or disposition. Our Manager and its affiliates refer to our board any acquisition opportunities in accordance with the U.S. acquisition priorities below that are made available to MAM division of Macquarie unless our chief executive officer determines that such opportunity does not meet our acquisition criteria adopted by our board. To the extent Macquarie entities outside MAM division develop or become aware of acquisition opportunities, they are not obligated to offer us these opportunities.
Pursuant to our Management Services Agreement, we have priority ahead of all current and future entities managed by our Manager or by members of Macquarie within the MAM division in each of the following acquisition opportunities that are within the U.S.:
airport fixed base operations;
airport parking;
district energy; and,
"user pays", contracted and regulated assets (as defined below) that represent an investment of greater than AUD $40 million.
“User pays” assets mean businesses that are transportation- related and derive a majority of their revenues from a per use fee or charge.
Contracted assets mean businesses that derive a majority of their revenues from long-term contracts with other businesses or governments.
Regulated assets mean businesses that are the sole or predominant providers of at least one essential service in their service areas and where the level of revenue generated or charges imposed are regulated by government entities.
We have priority ahead of all current and future entities managed by our Manager or any Manager affiliate in all investment opportunities originated by a party other than our Manager or any Manager affiliate where such party offers the opportunity exclusively to us and not to any other entity managed by our Manager or any Manager affiliate within MAM division. Other than these four specific types of opportunities, our Manager does not have an obligation to offer to us any particular acquisition opportunities, even if they meet our investment objectives, and our Manager and its affiliates can offer any or all other acquisition opportunities on a priority basis or otherwise to current and future funds, investment vehicles and accounts sponsored by our Manager or its affiliates. We may compete with these entities for investment opportunities, and there can be no assurance that we will prevail with respect to such investments.
In addition, our management may determine not to pursue investment opportunities presented to us by our Manager, including those presented on a priority basis. If our management waives any such opportunity, our Manager and its affiliates
107

TABLE OF CONTENTS
may offer such opportunity to any other entity, including any entities sponsored or advised by members of MAM division of Macquarie. As such, every acquisition opportunity presented to us by our Manager may not be pursued by us and may ultimately be presented to entities with whom we compete for investments.
Financial Advisor
Affiliates of Macquarie, including Macquarie Capital (USA) Inc., or MCUSA, have preferred provider status in respect of any financial advisory services to be contracted for by us. If we contract with MCUSA for such services, such contracts will be based on market terms and subject to approval by our audit committee. Any fees payable to MCUSA for such financial advisory services are in addition to fees paid under the Management Services Agreement. The use of MCUSA does not preclude our use of similar services provided by any third-party vendors, and we have used other advisors from time to time.
OTHER TRANSACTIONS WITH MACQUARIE

Advisory Services
The Macquarie Group, and wholly-owned subsidiaries within the Macquarie Group, including Macquarie Bank Limited and Macquarie Capital (USA) Inc., have provided various advisory and other services and incurred expenses in connection with the Company’s equity raising activities, acquisitions, and debt structuring for the Company and its businesses. Underwriting fees are recorded in unitholders’ equity as a direct cost of equity offerings. Advisory fees and out-of-pocket expenses relating to acquisitions are expensed as incurred. Debt arranging fees are deferred and amortized over the term of the credit facility.
Long-Term Debt
The Company had a $600 million senior secured revolving credit facility at the holding company level to which Macquarie Capital Funding LLC had a $40 million commitment. On January 19, 2021, the commitments on the senior secured revolving credit facility were terminated in accordance with the terms of that agreement.
