All intercompany transactions and balances have been eliminated in the consolidation.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Use of Estimates</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principals ("GAAP") and the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, the reported amounts of revenue and expenses during the reporting period and the accompanying notes. Estimates are used for, but not limited to, the allocation of the value of purchase consideration for business acquisitions and other contingencies, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, the attainment of performance-based restricted stock units, stock-based compensation forfeiture rates, accrued liabilities and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and fluctuations in information technology spending by prospective customers can increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the consolidated financial statements in future periods.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Foreign Currency Translation</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company transacts business in various foreign currencies. In general, the functional currency of a foreign operation is the local country’s currency. Accordingly, the foreign currencies are translated into U.S. Dollars using exchange rates in effect at period end for assets and liabilities and average rates during each reporting period for the results of operations. Adjustments resulting from the translation of the financial statements of the foreign subsidiaries are reported as a separate component of accumulated other comprehensive income (loss) on the consolidated balance sheets. Foreign currency transaction gains and losses are included in interest income and other income (expense), net in the accompanying consolidated statements of comprehensive loss.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Derivative Financial Instruments </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">During 2017 and 2016, the Company entered into foreign currency derivative contracts with financial institutions to reduce the risk that its cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in Euros, Australian dollars, British Pound Sterling and Canadian dollars. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with cash, accounts receivable and intercompany receivables and payables. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. As of December 31, 2017 and 2016, the foreign currency derivative contracts that were not settled were recorded at fair value on the consolidated balance sheets. See Note 5, Fair Value Measurements, for a discussion regarding the valuation of the Company's derivative financial instruments.</span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other expense to offset the gains or losses resulting from the settlement or remeasurement of the underlying </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">foreign currency denominated cash, receivables and payables. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Business Combinations</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company recognizes assets acquired, liabilities assumed, and contingent consideration at their fair value on the acquisition date. The Company’s estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to </span><span style="font-family:inherit;font-size:10pt;">one year</span><span style="font-family:inherit;font-size:10pt;"> from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with a corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of comprehensive loss. See Note 2, Acquisitions, for a discussion of the Company's acquisitions during 2017 and 2016.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition, uncertainties in income tax and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company continues to gather information and evaluate these items and records any adjustments to the preliminary estimates to goodwill when the estimates are within the measurement period. Subsequent to the measurement period, changes to these income tax uncertainties and tax related valuation allowances will affect the Company's provision for income taxes in its consolidated statements of comprehensive loss. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company estimates the fair value of an indemnity holdback payable, which relates to business combinations, based on the contract value. The terms of the holdback payable include standard representations and warranties. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company estimates the fair value of the contingent consideration issued in business combinations using a probability-based income approach. The fair value of the Company's liability-classified contingent consideration is remeasured at each reporting period, with any changes in the fair value recorded as income or expense. Contingent acquisition consideration payable is included in accrued liabilities on the Company's consolidated balance sheets.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Cash and Cash Equivalents and Investments</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company considers all highly liquid instruments with an original maturity on the date of purchase of three months or less to be cash equivalents. Cash equivalents as of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;"> and 2016 consisted of money market funds. The Company determines the appropriate classification of investment securities at the time of purchase and re-evaluates such designation as of each balance sheet date. As of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;"> and 2016, all investment securities were designated as "available-for-sale." The Company considers available-for-sale securities that have an original maturity date longer than three months on the date of purchase to be short-term investments, including those investments that have a maturity date of longer than one year that are highly liquid and for which the Company does not have a positive intent to hold to maturity. These securities are carried at estimated fair value based on quoted market prices or other readily available market information, with the unrealized gains and losses included in accumulated other comprehensive income (loss) on the consolidated balance sheets. Recognized gains and losses are included in the consolidated statement of comprehensive loss. When the Company has determined that an other-than-temporary decline in fair value has occurred, the amount of the decline is recognized in earnings. Gains and losses are determined using the specific identification method.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Allowance for Doubtful Accounts</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company reduces gross trade accounts receivable with its allowance for doubtful accounts. The allowance for doubtful accounts is the Company's estimate of the amount of probable credit losses in existing accounts receivable. Management analyzes accounts receivable and historical bad debt experience, customer creditworthiness, current economic trends and changes in customer payment history when evaluating the adequacy of the allowance for doubtful accounts. Provisions to the allowance for doubtful accounts are recorded in general and administrative expenses in the Company's consolidated statements of comprehensive loss.</span></div><div

The deferred costs mainly represent commission payments to the Company's direct sales force and third parties for on-demand subscription and maintenance agreements, which the Company amortizes as sales and marketing expense over the non-cancellable term of the contract as the related revenue is recognized. The commission payments are a direct and incremental cost of the revenue arrangements.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Property and Equipment, net</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Property and equipment, net is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, generally two to eight years. Leasehold improvements are amortized over the lesser of the assets' estimated useful lives or the related lease terms. Expenditures for maintenance and repairs are expensed as incurred. Cost and accumulated depreciation of assets sold or retired are removed from the respective property accounts and any resulting gain or loss is reflected in the consolidated statements of comprehensive loss.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company capitalizes certain internal software costs. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. Capitalized costs are recorded as part of property and equipment. Maintenance and training costs are expensed as incurred. Internal use software is amortized on a straight line basis over its estimated useful life, generally </span><span style="font-family:inherit;font-size:10pt;">two</span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;">five</span><span style="font-family:inherit;font-size:10pt;"> years. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Goodwill, Intangible Assets, Long-Lived Assets and Impairment Assessments</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Goodwill represents the excess of the purchase price over the fair value of net assets acquired in connection with business combinations. Goodwill is not amortized, but instead goodwill is required to be tested for impairment annually and more frequently under certain circumstances. The Company performs such testing of goodwill in the fourth quarter of each year, and earlier if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company conducts a two-step test for impairment of goodwill. The first step of the test for goodwill impairment compares the fair value of the applicable reporting unit with its carrying value. If the fair value of a reporting unit is less than the reporting unit's carrying value, the Company will perform the second step of the test for impairment of goodwill. During the second step of the test for impairment of goodwill, the Company will compare the implied fair value of the reporting unit's goodwill with the carrying value of that goodwill. If the carrying value of the goodwill exceeds the calculated implied fair value, the excess amount will be recognized as an impairment loss. The Company has </span><span style="font-family:inherit;font-size:10pt;"><span>one</span></span><span style="font-family:inherit;font-size:10pt;"> reporting unit and evaluates goodwill for impairment at the entity level. Based upon the results of the step one testing, the Company concluded that no impairment existed as of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;">, and did not perform the second step of the goodwill impairment test.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Intangible assets with finite lives are amortized over their estimated useful lives of </span><span style="font-family:inherit;font-size:10pt;">one</span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;">twelve years</span><span style="font-family:inherit;font-size:10pt;">.

If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value. There were no material impairment charges recorded during the years ended </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;">, </span><span style="font-family:inherit;font-size:10pt;">2016</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">2015</span><span style="font-family:inherit;font-size:10pt;">.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Deferred Revenue</span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Deferred revenue consists of invoicing and payments received in advance of revenue recognition and is recognized once the revenue recognition criteria are met. The Company invoices its customers annually, quarterly, or in monthly installments. Deferred revenue that will be recognized during the succeeding twelve-month period is recorded as current deferred revenue and the remaining portion is recorded as non-current deferred revenue.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Revenue Recognition</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">     The Company generates revenue by providing software as a service ("SaaS") solutions through on-demand subscription and term licenses, related software maintenance associated with the Company's existing on-premise solution, and professional services. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Recurring Revenue. </span><span style="font-family:inherit;font-size:10pt;">Recurring revenue, which includes SaaS revenue and maintenance revenue, is recognized ratably over the stated contractual period. SaaS revenue consists of subscription fees from customers accessing the Company's cloud-based service offerings. Maintenance revenue consists of fees from customers purchasing licenses and receiving support for such on-premise solutions. The Company also recognizes SaaS and maintenance revenue associated with customers using its products in excess of contracted usage ("Overages"). Overages are primarily attributed to SaaS products and such Overages are recorded in SaaS revenue in the period incurred. Revenue related to Overages was immaterial for all years presented.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Service and License Revenue. </span><span style="font-family:inherit;font-size:10pt;">Service and license revenue primarily consists of training, integration and configuration services. Generally, the Company's professional services arrangements are billed on a time-and-materials basis. Time and material services are recognized as the services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional services arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of total estimated hours to complete the project. If the Company does not have a sufficient basis to measure progress toward completion, revenue is recognized upon completion. Service and license revenue also includes revenue from perpetual licenses, which is recognized upon delivery of the product, using the residual method, assuming all the other conditions for revenue recognition have been met. Revenue related to perpetual licenses was immaterial for all the years presented.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In a limited number of arrangements with non-standard acceptance criteria, the Company defers the revenue until the acceptance criteria are satisfied. Reimbursements, including those related to travel and out-of-pocket expenses, are included in services and license revenue, and an equivalent amount of reimbursable expenses is included in cost of services and license revenue. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In general, recurring revenue agreements are entered into for </span><span style="font-family:inherit;font-size:10pt;"><span>12</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>36</span></span><span style="font-family:inherit;font-size:10pt;"> months, and the professional services are performed within nine months of entering into a contract with the customer, depending on the size of integration.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">SaaS agreements provide specified service level commitments, excluding scheduled maintenance.

The Company determines the best estimated selling price of each deliverable in an arrangement based on a selling price hierarchy of methods contained in Finance Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2009-13, "Revenue Recognition (Accounting Standards Codification (“ASC”) Topic 605)-</span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Multiple-Deliverable Revenue Arrangements." </span><span style="font-family:inherit;font-size:10pt;">The best estimated selling price for a deliverable is based on its vendor-specific objective evidence (“VSOE”), if available, third-party evidence (“TPE”), if VSOE is not available, or estimated selling price (“ESP”), if neither VSOE nor TPE is available. Total arrangement fees are allocated to each element using the relative selling price method. The Company has currently established VSOE for most deliverables, except for fixed fee service arrangements and on-premise software licenses. </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company considered all of the following factors to establish the ESP for fixed fee service arrangements when sold with its on-demand services: the weighted average actual sales prices of professional services sold on a stand-alone basis for on-demand services; average billing rates for fixed fee service agreements when sold with on-demand services, cost plus a reasonable mark-up and other factors such as gross margin objectives, pricing practices and growth strategy. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">        </span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Multiple-deliverable arrangements with on-premise license. </span><span style="font-family:inherit;font-size:10pt;">For arrangements with multiple deliverables, including license, professional services and maintenance, the Company recognizes license revenue using the residual method of accounting pursuant to the requirements of the guidance contained in ASC 985-605, "</span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Software Revenue Recognition.</span><span style="font-family:inherit;font-size:10pt;">" Under the residual method, revenue is recognized when VSOE for fair value exists for all of the undelivered elements in the arrangement, but does not exist for one or more of the delivered elements in the arrangement. If evidence of fair value cannot be established for the undelivered elements, all of the revenue is deferred until evidence of fair value can be established, or until the items for which evidence of fair value cannot be established are delivered. For maintenance and certain professional services, the Company has established VSOE because it has a sufficient history of selling these deliverables at an established price.

Stock-based compensation expense for restricted stock units is estimated based on the closing price of the Company's common stock on the date of grant and the estimated forfeiture rate, which is based on historical forfeitures. The Company measures stock-based compensation expense for employee stock purchase plan shares using the Black-Scholes-Merton option pricing model. These </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">variables include: the expected term of the plan, taking into account projected exercises; the Company's expected stock price volatility over the expected term of the awards; the risk-free interest rate; and expected dividends. The Company estimates forfeiture rate based on an analysis of actual forfeitures and they will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience and other factors.

In 2017, the Company granted performance-based restricted stock units with vesting contingent on successful attainment of annualized SaaS revenue growth and Non-GAAP annual operating margin targets over the three-year period from January 1, 2017 through December 31, 2019. In 2016, the Company granted PSU's with vesting contingent on attainment of pre-set quota for the EMEA region over the three-year period from January 1, 2016 through December 31, 2018. The Company also granted PSUs to its CEO with vesting contingent upon the Company's relative total shareholder return over a three year period (2016-2018) compared to the Company's 2016 executive compensation peer group companies. In 2015, the Company granted PSUs with vesting contingent on its annualized SaaS revenue growth over the three-year period from July 1, 2015 to June 30, 2018. In 2014, the Company granted PSUs with vesting contingent on its annualized SaaS revenue growth over the three-year period from January 1, 2014 to December 31, 2016, and on the Company's relative total shareholder return over the same three-year period compared to an index of 17 SaaS companies. These PSUs will, to the extent the performance criteria are achieved, vest on the third anniversary of the grant date.

This process involves estimating actual current tax assets and liabilities together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the consolidated balance sheets. Net deferred tax assets are recorded to the extent the Company believes that it is more-likely-than-not to be realized. In making such determination, all available positive and negative evidence is considered, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. Except for the net deferred tax assets of some of the Company's foreign subsidiaries, the Company maintained a full valuation allowance against its net deferred tax assets at </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;"> because the Company believes that it is not more-likely-than-not that the gross deferred tax assets will be realized. While the Company has considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance, in the event the Company was able to determine that it would be able to realize the deferred tax assets in the future, an adjustment to the valuation allowance would increase net income in the period such determination was made.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company regularly reviews its tax positions and benefits to be realized. The Company recognizes tax liabilities based upon its estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company recognizes interest and penalties related to income tax matters as income tax expense. Interest or penalties associated with unrecognized tax benefits was immaterial for all the years presented.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Comprehensive Income (Loss)</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Comprehensive income (loss) is the total of net income (loss), unrealized gains and losses on investments and foreign currency translation adjustments.

The amendments require entities to record all tax effects related to stock-</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">based payments at settlement or expiration through the income statement and the windfall tax benefit to be recorded when it arises, subject to normal valuation allowance considerations. All tax-related cash flows resulting from the stock-based payments are required to be reported as operating activities in the statement of cash flows. Further, the amendments allow entities to make an accounting policy election to either estimate forfeitures or recognize forfeitures as they occur. The Company adopted this guidance on January 1, 2017 on a prospective basis. Adoption of the new standard did not have a material impact to the Company's consolidated financial statements and resulted in the recognition of excess tax benefits to the Company's income taxes rather than paid-in capital. The Company elected to continue to estimate forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period.</span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Recently Issued, But Not Yet Adopted Accounting Pronouncements</span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In May 2017, the FASB issued ASU 2017-09, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Scope of Modification Accounting</span><span style="font-family:inherit;font-size:10pt;">, which amends the scope of modification accounting for stock-based payment arrangements, provides guidance on the types of changes to the terms or conditions of stock-based payment awards to which an entity would be required to apply modification accounting under ASC 718, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Compensation- Stock Compensation</span><span style="font-family:inherit;font-size:10pt;">.

The guidance is effective for the Company's fiscal year beginning January 1, 2018. Restricted cash will be included as a component of cash, cash equivalents, and restricted cash on the Company's consolidated statement of cash flows. The inclusion of restricted cash will increase the beginning and ending balances of the consolidated statement of cash flows by </span><span style="font-family:inherit;font-size:10pt;"><span>$1.4 million</span></span><span style="font-family:inherit;font-size:10pt;">. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2016, the FASB issued ASU 2016-15,</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments</span><span style="font-family:inherit;font-size:10pt;">. The guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice for certain cash receipts and cash payments. The amendments in this guidance are effective for public business entities for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Entities are permitted to adopt the standard early in any interim or annual period, and a retrospective application is required. While the Company continues to assess the impact of this standard, it does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Leases, </span><span style="font-family:inherit;font-size:10pt;">which requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. The new standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases and amounts previously recognized in accordance with the business combinations guidance for leases. The updated standard is effective for the Company beginning in the first quarter of 2019. The Company is currently evaluating the impact of this new standard on its consolidated financial statements. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued ASU No. 2014-09, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers </span><span style="font-family:inherit;font-size:10pt;">("Topic 606").

In addition, the impact to commissions will result in a decrease to accumulated deficit, offset by an increase in prepaid and other current assets and deposits and other assets.

Estimates are used for, but not limited to, the allocation of the value of purchase consideration for business acquisitions and other contingencies, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, the attainment of performance-based restricted stock units, stock-based compensation forfeiture rates, accrued liabilities and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and fluctuations in information technology spending by prospective customers can increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the consolidated financial statements in future periods. </us-gaap:UseOfEstimates>

In general, the functional currency of a foreign operation is the local country’s currency. Accordingly, the foreign currencies are translated into U.S. Dollars using exchange rates in effect at period end for assets and liabilities and average rates during each reporting period for the results of operations. Adjustments resulting from the translation of the financial statements of the foreign subsidiaries are reported as a separate component of accumulated other comprehensive income (loss) on the consolidated balance sheets. Foreign currency transaction gains and losses are included in interest income and other income (expense), net in the accompanying consolidated statements of comprehensive loss. </us-gaap:ForeignCurrencyTransactionsAndTranslationsPolicyTextBlock>

The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in Euros, Australian dollars, British Pound Sterling and Canadian dollars. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with cash, accounts receivable and intercompany receivables and payables. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. As of December 31, 2017 and 2016, the foreign currency derivative contracts that were not settled were recorded at fair value on the consolidated balance sheets. See Note 5, Fair Value Measurements, for a discussion regarding the valuation of the Company's derivative financial instruments.</span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other expense to offset the gains or losses resulting from the settlement or remeasurement of the underlying </span></div>foreign currency denominated cash, receivables and payables. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties.

As a result, during the measurement period, which may be up to </span><span style="font-family:inherit;font-size:10pt;">one year</span><span style="font-family:inherit;font-size:10pt;"> from the acquisition date, the Company may record adjustments to the fair value of assets acquired and liabilities assumed, with a corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of comprehensive loss.

The Company continues to gather information and evaluate these items and records any adjustments to the preliminary estimates to goodwill when the estimates are within the measurement period. Subsequent to the measurement period, changes to these income tax uncertainties and tax related valuation allowances will affect the Company's provision for income taxes in its consolidated statements of comprehensive loss. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company estimates the fair value of an indemnity holdback payable, which relates to business combinations, based on the contract value. The terms of the holdback payable include standard representations and warranties. </span></div>The Company estimates the fair value of the contingent consideration issued in business combinations using a probability-based income approach. The fair value of the Company's liability-classified contingent consideration is remeasured at each reporting period, with any changes in the fair value recorded as income or expense. Contingent acquisition consideration payable is included in accrued liabilities on the Company's consolidated balance sheets.

Cash and Cash Equivalents and Investments<span style="font-family:inherit;font-size:10pt;">The Company considers all highly liquid instruments with an original maturity on the date of purchase of three months or less to be cash equivalents. Cash equivalents as of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;"> and 2016 consisted of money market funds.

As of </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span> and 2016, all investment securities were designated as "available-for-sale." The Company considers available-for-sale securities that have an original maturity date longer than three months on the date of purchase to be short-term investments, including those investments that have a maturity date of longer than one year that are highly liquid and for which the Company does not have a positive intent to hold to maturity. These securities are carried at estimated fair value based on quoted market prices or other readily available market information, with the unrealized gains and losses included in accumulated other comprehensive income (loss) on the consolidated balance sheets. Recognized gains and losses are included in the consolidated statement of comprehensive loss. When the Company has determined that an other-than-temporary decline in fair value has occurred, the amount of the decline is recognized in earnings. Gains and losses are determined using the specific identification method.

The allowance for doubtful accounts is the Company's estimate of the amount of probable credit losses in existing accounts receivable.

Goodwill is not amortized, but instead goodwill is required to be tested for impairment annually and more frequently under certain circumstances. The Company performs such testing of goodwill in the fourth quarter of each year, and earlier if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company conducts a two-step test for impairment of goodwill. The first step of the test for goodwill impairment compares the fair value of the applicable reporting unit with its carrying value. If the fair value of a reporting unit is less than the reporting unit's carrying value, the Company will perform the second step of the test for impairment of goodwill. During the second step of the test for impairment of goodwill, the Company will compare the implied fair value of the reporting unit's goodwill with the carrying value of that goodwill. If the carrying value of the goodwill exceeds the calculated implied fair value, the excess amount will be recognized as an impairment loss. The Company has </span><span style="font-family:inherit;font-size:10pt;"><span>one</span></span><span style="font-family:inherit;font-size:10pt;"> reporting unit and evaluates goodwill for impairment at the entity level.

If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value.

Revenue Recognition<div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">     The Company generates revenue by providing software as a service ("SaaS") solutions through on-demand subscription and term licenses, related software maintenance associated with the Company's existing on-premise solution, and professional services. Amounts that have been invoiced are recorded in accounts receivable and in deferred revenue or revenue, depending on whether the revenue recognition criteria have been met. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Recurring Revenue. </span><span style="font-family:inherit;font-size:10pt;">Recurring revenue, which includes SaaS revenue and maintenance revenue, is recognized ratably over the stated contractual period. SaaS revenue consists of subscription fees from customers accessing the Company's cloud-based service offerings. Maintenance revenue consists of fees from customers purchasing licenses and receiving support for such on-premise solutions. The Company also recognizes SaaS and maintenance revenue associated with customers using its products in excess of contracted usage ("Overages"). Overages are primarily attributed to SaaS products and such Overages are recorded in SaaS revenue in the period incurred. Revenue related to Overages was immaterial for all years presented.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Service and License Revenue. </span><span style="font-family:inherit;font-size:10pt;">Service and license revenue primarily consists of training, integration and configuration services. Generally, the Company's professional services arrangements are billed on a time-and-materials basis. Time and material services are recognized as the services are rendered based on inputs to the project, such as billable hours incurred. For fixed-fee professional services arrangements, the Company recognizes revenue under the proportional performance method of accounting and estimates the proportional performance on a monthly basis, utilizing hours incurred to date as a percentage of total estimated hours to complete the project. If the Company does not have a sufficient basis to measure progress toward completion, revenue is recognized upon completion. Service and license revenue also includes revenue from perpetual licenses, which is recognized upon delivery of the product, using the residual method, assuming all the other conditions for revenue recognition have been met. Revenue related to perpetual licenses was immaterial for all the years presented.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In a limited number of arrangements with non-standard acceptance criteria, the Company defers the revenue until the acceptance criteria are satisfied. Reimbursements, including those related to travel and out-of-pocket expenses, are included in services and license revenue, and an equivalent amount of reimbursable expenses is included in cost of services and license revenue. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In general, recurring revenue agreements are entered into for </span><span style="font-family:inherit;font-size:10pt;"><span>12</span></span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;"><span>36</span></span><span style="font-family:inherit;font-size:10pt;"> months, and the professional services are performed within nine months of entering into a contract with the customer, depending on the size of integration.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">SaaS agreements provide specified service level commitments, excluding scheduled maintenance.

Stock-Based Compensation<div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Stock-based compensation expense is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the requisite service period, which is generally the vesting period. Stock-based compensation expense for restricted stock units is estimated based on the closing price of the Company's common stock on the date of grant and the estimated forfeiture rate, which is based on historical forfeitures. The Company measures stock-based compensation expense for employee stock purchase plan shares using the Black-Scholes-Merton option pricing model. These </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">variables include: the expected term of the plan, taking into account projected exercises; the Company's expected stock price volatility over the expected term of the awards; the risk-free interest rate; and expected dividends. The Company estimates forfeiture rate based on an analysis of actual forfeitures and they will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience and other factors. Changes in these variables could affect stock-based compensation expense in the future.</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company granted performance-based restricted stock units ("PSUs") to select executives and other key employees. Vesting of the Company's PSUs is based on achievement of specified company or other goals. In 2017, the Company granted performance-based restricted stock units with vesting contingent on successful attainment of annualized SaaS revenue growth and Non-GAAP annual operating margin targets over the three-year period from January 1, 2017 through December 31, 2019. In 2016, the Company granted PSU's with vesting contingent on attainment of pre-set quota for the EMEA region over the three-year period from January 1, 2016 through December 31, 2018. The Company also granted PSUs to its CEO with vesting contingent upon the Company's relative total shareholder return over a three year period (2016-2018) compared to the Company's 2016 executive compensation peer group companies. In 2015, the Company granted PSUs with vesting contingent on its annualized SaaS revenue growth over the three-year period from July 1, 2015 to June 30, 2018. In 2014, the Company granted PSUs with vesting contingent on its annualized SaaS revenue growth over the three-year period from January 1, 2014 to December 31, 2016, and on the Company's relative total shareholder return over the same three-year period compared to an index of 17 SaaS companies. These PSUs will, to the extent the performance criteria are achieved, vest on the third anniversary of the grant date. PSU awards based on total shareholder return are recognized as compensation costs over the requisite service period, if rendered, even if the market condition is never satisfied. In determining the fair value of PSUs based on total shareholder return the Company considered the achievement of the market condition in the estimated fair value.</span></div>

Income Taxes<div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company is subject to income and foreign withholding taxes in both the United States and foreign jurisdictions and the Company uses estimates in determining its provision for income taxes. This process involves estimating actual current tax assets and liabilities together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the consolidated balance sheets. Net deferred tax assets are recorded to the extent the Company believes that it is more-likely-than-not to be realized. In making such determination, all available positive and negative evidence is considered, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. Except for the net deferred tax assets of some of the Company's foreign subsidiaries, the Company maintained a full valuation allowance against its net deferred tax assets at </span><span style="font-family:inherit;font-size:10pt;">December 31, 2017</span><span style="font-family:inherit;font-size:10pt;"> because the Company believes that it is not more-likely-than-not that the gross deferred tax assets will be realized. While the Company has considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance, in the event the Company was able to determine that it would be able to realize the deferred tax assets in the future, an adjustment to the valuation allowance would increase net income in the period such determination was made.</span></div>The Company regularly reviews its tax positions and benefits to be realized. The Company recognizes tax liabilities based upon its estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. The Company recognizes interest and penalties related to income tax matters as income tax expense. Interest or penalties associated with unrecognized tax benefits was immaterial for all the years presented.

The guidance is effective for the Company's fiscal year beginning January 1, 2018. Restricted cash will be included as a component of cash, cash equivalents, and restricted cash on the Company's consolidated statement of cash flows. The inclusion of restricted cash will increase the beginning and ending balances of the consolidated statement of cash flows by </span><span style="font-family:inherit;font-size:10pt;"><span>$1.4 million</span></span><span style="font-family:inherit;font-size:10pt;">. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In August 2016, the FASB issued ASU 2016-15,</span><span style="font-family:inherit;font-size:10pt;font-style:italic;"> Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments</span><span style="font-family:inherit;font-size:10pt;">. The guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice for certain cash receipts and cash payments. The amendments in this guidance are effective for public business entities for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Entities are permitted to adopt the standard early in any interim or annual period, and a retrospective application is required. While the Company continues to assess the impact of this standard, it does not expect the adoption of this ASU to have a material impact on its consolidated financial statements.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Leases, </span><span style="font-family:inherit;font-size:10pt;">which requires the recognition of assets and liabilities arising from lease transactions on the balance sheet and the disclosure of key information about leasing arrangements. Accordingly, a lessee will recognize a lease asset for its right to use the underlying asset and a lease liability for the corresponding lease obligation. Both the asset and liability will initially be measured at the present value of the future minimum lease payments over the lease term. Subsequent measurement, including the presentation of expenses and cash flows, will depend on the classification of the lease as either finance or an operating lease. Initial costs directly attributable to negotiating and arranging the lease will be included in the asset. For leases with a term of 12 months or less, a lessee can make an accounting policy election by class of underlying asset to not recognize an asset and corresponding liability. Lessees will also be required to provide additional qualitative and quantitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements and provide additional information about the nature of an organization’s leasing activities. The new standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases and amounts previously recognized in accordance with the business combinations guidance for leases. The updated standard is effective for the Company beginning in the first quarter of 2019. The Company is currently evaluating the impact of this new standard on its consolidated financial statements. </span></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued ASU No. 2014-09, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers </span><span style="font-family:inherit;font-size:10pt;">("Topic 606").

The Company has determined that the term of economic benefit of its costs to obtain customer contracts is approximately four years. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The two permitted transition methods under the new standard are the full retrospective method, under which Topic 606 would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, under which the cumulative effect of applying Topic 606 would be recognized at the date of initial application. Topic 606 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017.

In addition, the impact to commissions will result in a decrease to accumulated deficit, offset by an increase in prepaid and other current assets and deposits and other assets. The Company is currently quantifying the impact of this new standard on its consolidated financial statements.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>Except for the updated accounting standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to the Company's consolidated financial statements.

(collectively, “Versata”) filed suit against the Company in the United States District Court for the District of Delaware (“Delaware District Court”). The suit asserted that the Company infringed U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024. On May 30, 2013, the Company answered the complaint and filed a counterclaim in the Delaware District Court. The Company's counterclaim asserted that Versata infringed U.S. Patent Nos. 6,269,355, 6,850,924 and 6,473,748. On August 30, 2013, the Company filed petitions with the United States Patent and Trademark Office Patent Trial and Appeal Board (“PTAB”) for covered business method (“CBM”) patent review of U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024, which Versata filed responses to on December 12, 2013. The Company also filed a motion with the Delaware District Court on August 30, 2013 to stay the litigation pending completion of the patent review proceedings with the PTAB (“Motion to Stay”). On January 8, 2014, the Company was granted leave by the Delaware District Court to add Versata Inc. (included in the above definition of “Versata”) as a counterclaim defendant. On March 4, 2014, the PTAB instituted covered business method patent review of each of Versata’s patents, namely, U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024, finding it more likely than not that the Company would prevail in establishing that the challenged claims were not patentable. After requesting the PTAB to reconsider its decision to institute, which was denied, Versata filed a petition for writ of mandamus with the Court of Appeals for the Federal Circuit (“CAFC”) on April 11, 2014 asking that Court to deny institution of CBM patent review by the PTAB. The CAFC denied Versata’s petition for writ of mandamus on May 5, 2014. On April 17, 2014, the Company filed additional petitions with the PTAB for CBM patent review to address all of the remaining claims not previously covered in the prior petitions with respect to U.S Patent Nos. 7,908,304 and 7,958,024. On May 8, 2014, the Delaware District Court: (i) granted our Motion to Stay in part with respect to U.S. Patent No. 7,904,326, and (ii) denied the Company's Motion to Stay in part with respect to U.S. Patent Nos. 7,908,304 and 7,958,024. On May 8, 2014, the Company appealed to the CAFC the Delaware District Court’s denial of the Motion to Stay with respect to U.S. Patent Nos. 7,908,304 and 7,958,024. On October 2, 2014, the PTAB instituted covered business method patent review of the remaining claims covered in the second set of petitions for U.S Patent Nos. 7,908,304 and 7,958,024. On October 21, 2014, the Company engaged in a mediation with Versata and on November 13, 2014, entered into an agreement with Versata to settle and dismiss the pending district court litigation and patent office proceedings, to extend patent cross-licenses and covenants not to sue to one another, and the Company was appointed as an authorized reseller of certain Versata products. Under the agreement, each party covenanted not to sue the other (and its related entities) for infringement of any patents now owned (including pending patents) or later acquired by either party. In addition, each party granted to the other a fully paid-up, irrevocable, nonexclusive, worldwide license to certain patents (including the patents asserted in the pending district court litigation) for specified products of each party. The agreement also contained a release for any past infringement or claim between the parties and dismissal of the civil pending in the Delaware District Court, as well as the five covered business method patent review proceedings then-pending before the PTAB. Pursuant to the agreement, the Company agreed to pay to Versata </span><span style="font-family:inherit;font-size:10pt;"><span>$4.5 million</span></span><span style="font-family:inherit;font-size:10pt;"> in nine equal quarterly installments, commencing on January 31, 2015. The fair value of these payments was </span><span style="font-family:inherit;font-size:10pt;"><span>$4.3 million</span></span><span style="font-family:inherit;font-size:10pt;">, of which the Company recognized a charge to earnings for $</span><span style="font-family:inherit;font-size:10pt;"><span>2.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> in 2014 and capitalized $</span><span style="font-family:inherit;font-size:10pt;"><span>1.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> for the value of the patent license. The $</span><span style="font-family:inherit;font-size:10pt;"><span>1.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> will be amortized to expense over the average life span of the associated patents of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>9.5</span></span><span style="font-family:inherit;font-size:10pt;"> years. The difference between the installment payment and the fair value will be charged to interest as incurred.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;text-decoration:underline;">Callidus Software Inc.</span><span style="font-family:inherit;font-size:10pt;text-decoration:underline;"> v. </span><span style="font-family:inherit;font-size:10pt;font-style:italic;text-decoration:underline;">Xactly Corporation</span><span style="font-family:inherit;font-size:10pt;text-decoration:underline;"> - Settled</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On August 31, 2012, the Company filed suit against Xactly Corporation (“Xactly”) in the United States District Court for the Central District of California. The suit alleged that Xactly infringed U.S. Patents 8,046,387 and 7,774,378. On October 24, 2012, the Company amended its complaint to add Xactly's President and Chief Executive Officer as a defendant and to add claims for trademark infringement, false advertising, false and misleading advertising, trade libel, defamation, intentional interference with prospective economic advantage, intentional interference with contractual relations, breach of contract and unfair competition, in addition to patent infringement. On January 28, 2013, the Company further amended its complaint to allege that Xactly also infringed U.S. Patent 6,473,748 and dismissed its intentional interference with contractual relations </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">claim. On March 14, 2013, the case was transferred to the United States District Court in the Northern District of California. On May 31, 2013, the Company and Xactly entered into a stipulated dismissal of the Company's trademark infringement claim whereby Xactly agreed that it would not use the Company's trademarks-in-suit in certain of Xactly's marketing and advertising activities going forward. On November 25, 2013, Callidus, Xactly and Xactly's President and Chief Executive Officer entered into a Settlement, Release, and License Agreement that, among other things, included an agreement by Xactly to pay the Company $</span><span style="font-family:inherit;font-size:10pt;"><span>2.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> in license fee, which will be paid in four equal annual installments of $</span><span style="font-family:inherit;font-size:10pt;"><span>0.5 million</span></span><span style="font-family:inherit;font-size:10pt;"> beginning November 2013 and with the final payment in November 2016. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Other matters</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition to the above litigation matters, the Company from time to time is a party to other various litigation and customer disputes incidental to the conduct of its business. At the present time, the Company believes that none of these matters are likely to have a material adverse effect on the Company's future financial results.</span></div>The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company reviews the need for any such liability on a quarterly basis and records any necessary adjustments to reflect the effect of ongoing negotiations, contract disputes, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case in the period they become known. At December 31, 2017, the Company has not recorded any such liabilities in accordance with accounting for contingencies. However, litigation is subject to inherent uncertainties and the Company's view on these matters may change in the future.

in 2003 and amended and restated in 2013, qualifies as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code. The ESPP is designed to enable eligible employees to purchase shares of the Company's common stock at a discount on a periodic basis through payroll deductions. Each offering period under the ESPP covers </span><span style="font-family:inherit;font-size:10pt;"><span>12 months</span></span><span style="font-family:inherit;font-size:10pt;"> and consists of </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> consecutive six-month purchase periods. The purchase price for shares of common stock purchased under the ESPP is </span><span style="font-family:inherit;font-size:10pt;"><span>85%</span></span><span style="font-family:inherit;font-size:10pt;"> of the lesser of the fair market value of the Company's common stock on the first day of the applicable offering period and the fair market value of the Company's common stock on the last day of each purchase period.

for income tax was a benefit in 2017 compared to an expense in 2016 which was primarily due to the benefits obtained from the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) in which the Company's initial analysis of the impact of this Tax Act resulted in a provisional federal discrete tax benefit of </span><span style="font-family:inherit;font-size:10pt;"><span>$1.6 million</span></span><span style="font-family:inherit;font-size:10pt;"> in the period ending December 31, 2017. The tax benefit is primarily driven by the corporate rate reduction and the reassessment of the realizability of our deferred tax assets and liabilities. Since the Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, we consider the accounting of the deferred tax re-measurements, realizability of net deferred tax assets/liabilities, and transition tax to be incomplete due to the forthcoming guidance and our ongoing analysis of final year-end data and tax positions. The Company expects to complete its analysis within the measurement period in accordance with the SEC staff issued Staff Accounting Bulletin 118 (“SAB 118”). This benefit was offset by an increase in sales to foreign customers subject to withholding taxes.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">On December 22, 2017, this Tax Act was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. We are required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, re-measuring our U.S. deferred tax assets and liabilities as well as reassessing the net realizability of our deferred tax assets and liabilities.</span></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">SAB 118 provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, </span><span style="font-family:inherit;font-size:10pt;font-style:italic;">Income Taxes</span><span style="font-family:inherit;font-size:10pt;">. However, in accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span

management considers whether it is more likely than not that some portion or all of the deferred tax assets will 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. Based on the level of historical taxable income and projections for future taxable income over the period in which the temporary differences are deductible, the Company recorded a valuation allowance against the deferred tax assets for which it believes it is not more likely than not to be realized. As of December 31, 2017 and 2016, a valuation allowance has been recorded on all deferred tax assets, except the deferred tax assets related to some of its foreign subsidiaries, based on the analysis of profitability for those subsidiaries.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The net decrease in the valuation allowance for 2017 was $</span><span style="font-family:inherit;font-size:10pt;"><span>9.1 million</span></span><span style="font-family:inherit;font-size:10pt;">, mainly due to the release of the valuation allowance because of the Tax Act driven by the rate reduction and the reassessment of the realizability of the Company's deferred assets and liabilities.
