Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Use of Estimates The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, collectability of accounts receivable, costs to complete certain contracts, valuation of acquired assets and liabilities, valuation of stock options, income tax accruals and the value of deferred tax assets and liabilities. Estimates are also used to determine the remaining economic lives and carrying value of fixed assets, goodwill and intangible assets. Actual results could differ from those estimates. Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant accounts, transactions and profits between the consolidated companies have been eliminated in consolidation. Unconsolidated investments in entities over which the Company does not have control but has the ability to exercise influence over operating and financial policies, if any, are accounted for under the equity method of accounting. Earnings and losses from such investments are recorded on a pre-tax basis, if any. Certain prior year balances have been reclassified to conform to the current year presentation. Such reclassifications did not affect total revenues, operating income or net income. Revenue Recognition The Company’s payment terms for perpetual software licenses typically require that the total fee be paid upon signing of the contract. Maintenance services and term license fees are typically due in full at the beginning of each annual period. Professional services and software-enabled services are typically due and payable monthly in arrears. Normally, the Company’s arrangements do not provide for any refund rights, and payments are not contingent on specific milestones or customer acceptance conditions. For arrangements that do contain such provisions, the Company defers revenue until the rights or conditions have expired or have been met. Unbilled accounts receivable primarily relate to professional services and software-enabled services revenue that has been earned as of month end but is not invoiced until the subsequent month, and to software license revenue that has been earned and is realizable but not invoiced to clients until future dates specified in the client contract. Deferred revenue consists of billings or payments received related to product delivery, maintenance and other services, which have been paid by customers prior to the recognition of revenue. Deferred revenue relates primarily to cash received for maintenance and term license contracts in advance of services being performed over the contractual term. Software-enabled Services Revenue The Company primarily offers software-enabled outsourcing services in which the Company utilizes its own software to offer comprehensive fund administration services for alternative investment managers, including fund manager services, transfer agency services, funds-of-funds services, tax processing and accounting. The Company also offers subscription-based on-demand software applications that are managed and hosted at the Company’s facilities. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under these arrangements, the client does not have the right to take possession of the software, rather, the Company agrees to provide access to its applications, remote use of its equipment to process transactions, access to client’s data stored on its equipment, and connectivity between its environment and the client’s computing systems. Software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments, and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. The Company recognizes software-enabled services revenues on a monthly basis as the software-enabled services are provided and when persuasive evidence of an arrangement exists, the price is fixed or determinable and collectability is reasonably assured. The Company does not recognize any revenue before services are performed. Certain contracts contain additional fees for increases in market value, pricing and trading activity. Revenues related to these additional fees are recognized in the month in which the activity occurs based upon the Company’s summarization of account information and trading volume. Maintenance and Term Licenses Revenue Maintenance agreements generally require the Company to provide technical support and software updates (on a when-and-if-available basis) to its clients. Such services are generally provided under one-year renewable contracts. Maintenance revenues are recognized ratably over the term of the maintenance agreement. The Company also sells term licenses ranging from one to seven years, many of which include bundled maintenance services. For those arrangements with bundled maintenance services, vendor-specific objective evidence (“VSOE”) does not exist for the maintenance element and therefore the total fee is recognized ratably over the contractual term of the arrangement. Perpetual Licenses Revenue The Company follows the principles of accounting standards relating to software revenue recognition, which provide guidance on applying GAAP in recognizing revenue on software transactions. Accounting standards require that revenue recognized from software transactions be allocated to each element of the transaction based on the relative fair values of the elements, such as software products, specified upgrades, enhancements, post-contract client support, installation or training. The determination of fair value is based upon VSOE. The Company recognizes perpetual licenses revenues allocated to software products and enhancements generally upon delivery of each of the related products or enhancements, assuming all other revenue recognition criteria are met. In the rare occasion that a perpetual license agreement includes the right to a specified upgrade or product, the Company defers all revenues under the arrangement until the specified upgrade or product is delivered, since typically VSOE does not exist to support the fair value of the specified upgrade or product. The Company generally recognizes revenue from sales of software or products including proprietary software upon product shipment and receipt of a signed contract, provided that collection is probable and all other revenue recognition criteria are met. The Company sells perpetual software licenses in conjunction with professional services for installation and maintenance. For these arrangements, the total contract value is attributed first to the maintenance arrangement based on its fair value, which is derived from stated renewal rates. The contract value is then attributed to professional services based on estimated fair value, which is derived from the rates charged for similar services provided on a stand-alone basis. The Company’s software license agreements generally do not require significant modification or customization of the underlying software, and, accordingly, implementation services provided by the Company are not considered essential to the functionality of the software. The remainder of the total contract value is then attributed to the software license based on the residual method. The Company occasionally enters into license agreements requiring significant customization of the Company’s software. The Company accounts for the license fees under these agreements on the percentage-of-completion basis. This method requires estimates to be made for costs to complete the agreement utilizing an estimate of development man-hours remaining. Revenue is recognized each period based on the hours incurred to date compared to the total hours expected to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs may be revised. Such revisions are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are determined on a contract-by-contract basis, and are made in the period in which such losses are first estimated or determined. Professional Services Revenue The Company provides consulting and training services to its clients. Revenues for such services are generally recognized over the period during which the services are performed. The Company typically charges for professional services on a time-and-materials basis. However, some contracts are for a fixed fee. For the fixed-fee arrangements, an estimate is made of the total hours expected to be incurred to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs may be revised. Such revisions are recognized in the period in which the revisions are determined. Revenues are recognized each period based on the hours incurred to date compared to the total hours expected to complete the project. Research and Development Research and development costs associated with computer software are charged to expense as incurred. Capitalization of internally developed computer software costs in the case of software to be sold begins upon the establishment of technological feasibility based on a working model. Capitalization of internally developed computer software costs in the case of internal use software begins when management authorizes and commits funding to a project and the preliminary design stage has been completed. Net capitalized software costs of $12.1 million and $8.8 million are included in the December 31, 2017 and 2016 Consolidated Balance Sheets, respectively, under “Intangible and other assets”. The Company’s policy is to amortize these costs upon a product’s general release to the client. Amortization of capitalized software costs is calculated by the greater of (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product, including the period being reported on, typically two to five years. It is reasonably possible that those estimates of anticipated future gross revenues, the remaining estimated economic life of the product, or both could be reduced significantly due to competitive pressures. Amortization expense related to capitalized software development costs was $5.4 million, $3.5 million, and $2.4 million for each of the years ended December 31, 2017, 2016, and 2015, respectively. Stock-based Compensation Using the fair value recognition provisions of relevant accounting literature, stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the appropriate service period. Determining the fair value of stock-based awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of the Company’s stock price. Differences between actual results and these estimates could have a material effect on the Company’s financial results. A deferred income tax asset is recorded over the vesting period as stock compensation expense is recorded for non-qualified option awards. The realizability of the deferred tax asset is ultimately based on the actual value of the stock-based award upon exercise. If the actual value is lower than the fair value determined on the date of grant, then there would be an income tax expense for the portion of the deferred tax asset that is not realizable. Income Taxes The Company accounts for income taxes in accordance with the relevant accounting literature. An asset and liability approach is used to recognize deferred tax assets and liabilities for the future tax consequences of items that are recognized in the Company’s financial statements and tax returns in different years. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. The Company accounts for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was enacted into law and the new legislation contains several significant changes to U.S. tax law that affected the Company, including a one-time mandatory transition tax on accumulated foreign earnings and a reduction of the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate effective January 1, 2018, among others. The Tax Act also adds new provisions including limitations on the deductibility of interest expense and executive compensation, a minimum tax on global intangible low-taxed income (“GILTI”) and the base erosion anti-abuse tax (“BEAT”). The Company is required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, re-measuring the Company’s U.S. deferred tax assets and liabilities as well as reassessing the net realizability of the Company’s deferred tax assets and liabilities. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. Under U.S.GAAP, the Company can make an accounting policy election to either treat taxes due on the GILTI as a current period expense, or factor such amounts into our measurement of deferred taxes. The Company has elected the deferred method and recorded a reasonable estimate of $ 6.7 million related to GILTI. Income Tax Accounting Implications of the Tax Cuts and Jobs Act items to be incomplete due to the forthcoming guidance and the Company’s ongoing analysis of final year-end data and tax positions. The Company’s initial accounting for the GILTI tax is provisional under SAB 118 and is incomplete because the Company is still refining its measurement methodology. The Company is currently assessing the impact of other certain provisions, including the base erosion anti-abuse tax (“BEAT”), which does not apply to 2017. Additionally, the Company has considered the impact of limitations on the deductibility of interest expense and executive compensation on the realizability of its deferred tax assets and made a reasonable estimate that these changes do not significantly impact tax expense. The Cash and Cash Equivalents The Company considers all highly liquid marketable securities with original maturities of three months or less at the date of acquisition to be cash equivalents. The Company did not hold any cash equivalents at December 31, 2017 and 2016. Restricted Cash Restricted cash includes monies held by a bank as security for letters of credit issued due to lease requirements for office space. The letters of credit are expected to be renewed within the next twelve months, and as such, the restricted cash is classified as a current asset on the Consolidated Balance Sheets. Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation of property, plant and equipment is calculated using a combination of straight-line and accelerated methods over the estimated useful lives of the assets as follows: Description Useful Life Land — Buildings and improvements 40 years Equipment and software 3-5 years Furniture and fixtures 7-10 years Leasehold improvements Shorter of lease term or estimated useful life Depreciation expense for the years ended December 31, 2017, 2016 and 2015 was $25.9 million, $23.7 million and $18.9 million, respectively. Maintenance and repairs are expensed as incurred. The costs of sold or retired assets are removed from the related asset and accumulated depreciation accounts and any gain or loss is included in the Statements of Comprehensive Income (Loss). Goodwill and Intangible Assets The Company tests goodwill annually for impairment as of December 31 st The following table summarizes changes in goodwill (in thousands): Balance at December 31, 2015 $ 3,549,212 2016 acquisitions 148,235 Adjustments to prior acquisitions (4,787 ) Effect of foreign currency translation (39,927 ) Balance at December 31, 2016 $ 3,652,733 2017 acquisitions 13,328 Adjustments to prior acquisitions (621 ) Effect of foreign currency translation 42,383 Balance at December 31, 2017 $ 3,707,823 Customer relationships, completed technology, trade names and other identifiable intangible assets are amortized over lives ranging from three to 17 years based on the ratio that cash flows for the intangible asset bear to the total of expected future cash flows for the intangible asset. Amortization expense associated with customer relationships, completed technology and other amortizable intangible assets was $205.9 million, $201.5 million and $129.5 million for the years ended December 31, 2017, 2016 and 2015, respectively. A summary of the components of intangible assets is as follows (in thousands): December 31, 2017 2016 Customer relationships $ 1,665,814 $ 1,645,515 Completed technology 550,921 545,273 Trade names 61,093 60,128 Other 2,782 2,709 Total intangible assets 2,280,610 2,253,625 Less: accumulated amortization (938,833 ) (720,930 ) Total intangible assets, net $ 1,341,777 $ 1,532,695 Total estimated amortization expense, related to intangible assets, for each of the next five years, as of December 31, 2017, is expected to approximate (in thousands): Year Ending December 31, 2018 $ 211,256 2019 193,281 2020 174,492 2021 134,941 2022 118,670 Thereafter 509,137 Total $ 1,341,777 Impairment of Long-Lived Assets The Company evaluates the recoverability of its long-lived assets when there is evidence that events or changes in circumstances have made recovery of the assets’ carrying value unlikely. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. The Company has identified no such impairment losses in the years ended December 31, 2017 and 2016. Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, marketable securities, and trade receivables. The Company has cash investment policies that limit investments to investment grade securities. Concentrations of credit risk, with respect to trade receivables, are limited due to the fact that the Company’s client base is highly diversified. As of December 31, 2017 and 2016, the Company had no significant concentrations of credit. International Operations and Foreign Currency The functional currency of each foreign subsidiary is generally the local currency. Accordingly, assets and liabilities of foreign subsidiaries are translated to U.S. dollars at period-end exchange rates, and capital stock accounts are translated at historical rates. Revenues and expenses are translated using the average rates during the period. The resulting translation adjustments are excluded from net earnings and accumulated as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included within other (expense) income in the Consolidated Statements of Comprehensive Income (Loss) in the periods in which they occur. Comprehensive Income (Loss) Items defined as comprehensive income (loss), such as foreign currency translation adjustments, are separately classified in the Consolidated Financial Statements. The accumulated balance of other comprehensive income (loss) is reported separately from retained earnings and additional paid-in capital in the equity section of the Consolidated Balance Sheets. Total comprehensive income (loss) consists of net income (loss) and other accumulated comprehensive income (loss) disclosed in the equity section of the Consolidated Balance Sheets. Treasury Stock Treasury stock purchases are accounted for under the cost method and are included as a deduction from equity in the Stockholders’ Equity section of the Consolidated Balance Sheets. Under the cost method, the price paid for the stock is charged to the treasury stock account. Basic and Diluted Earnings per Share Earnings per share (“EPS”) is calculated in accordance with the relevant standards. Basic EPS includes no dilution and is computed by dividing income available to the Company’s common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of stock options, stock appreciation rights (“SARs”) and restricted stock units (“RSUs”) and restricted stock awards (“RSAs”) using the treasury stock method. Common equivalent shares are excluded from the computation of diluted earnings per share if the effect of including such common equivalent shares is anti-dilutive because their total assumed proceeds exceed the average fair value of common stock for the period. The Company has two classes of common stock, each with identical participation rights to earnings and liquidation preferences, and therefore the calculation of EPS as described above is identical to the calculation under the two-class method. The following table sets forth the computation of basic and diluted EPS (in thousands, except per share amounts): Year Ended December 31, 2017 2016 2015 Net income $ 328,864 $ 130,996 $ 42,862 Shares: Weighted average common shares outstanding — used in calculation of basic EPS 204,923 200,252 182,196 Weighted average common stock equivalents — options and restricted shares 6,709 5,541 8,700 Weighted average common and common equivalent shares outstanding — used in calculation of diluted EPS 211,632 205,793 190,896 Earnings per share - Basic $ 1.60 $ 0.65 $ 0.24 Earnings per share - Diluted $ 1.55 $ 0.64 $ 0.22 Weighted average stock options, SARs, RSUs and RSAs representing 10,641,582, 14,094,402 and 7,001,656 shares were outstanding for the years ended December 31, 2017, 2016 and 2015, respectively, but were not included in the computation of diluted EPS because the effect of including them would be anti-dilutive. Recently Adopted Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern Recent Accounting Pronouncements Not Yet Effective In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Subsequent to the issuance of ASU 2014-09, the FASB has issued the following updates: ASU 2016-08, Revenue from Contracts with Customers (Topic 606) – Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and Licensing Revenue from Contracts with Customers (Topic 606) – Narrow-Scope Improvements and Practical Expedients Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), and Revenue from contracts with Customers (Topic 606) Income Statement-Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from contracts with Customers (Topic 606) The Company will adopt the new revenue standard using the modified retrospective approach when it becomes effective for the Company in the first quarter of 2018. Once adopted, the Company will recognize the license component of term license arrangements upfront and the associated maintenance component will continue to be recognized over the contract period. Under the current revenue standard, for the majority of the Company’s term license arrangements which are bundled with maintenance services, both the term license and maintenance revenues are recognized ratably over the contract period. Upon adoption, the Company will record a one-time pre-tax cumulative effect adjustment of approximately $60 million to increase retained earnings. This amount represents the license component of existing term license arrangements, both in deferred revenue and yet to be billed, which has not yet been recognized and will never be recognized in the Company’s Consolidated Statements of Comprehensive Income (Loss) as a result of adopting the standard. The Company expects revenue recognition for the Company’s other revenue streams to remain materially consistent with its historical revenue recognition practices.

Equity [Abstract]
Stockholders' Equity	Note 4—Stockholders’ Equity Two-for-one Stock Split. On May 25, 2016, the Company’s Board of Directors approved a two-for-one stock split to be effected in the form of a stock dividend. The record date for the stock split was June 7, 2016 and the payment date was June 24, 2016. All share and per share amounts (other than for the Company’s Class A non-voting common stock) have been retroactively restated for all periods presented to reflect the stock split. Conversion of Class A Common Stock. On March 30, 2016, William C. Stone converted 2,703,846 shares of Class A non-voting stock into 2,703,846 shares of the Company’s common stock, or 5,407,692 shares of common stock on a post-split basis. Each share of Class A non-voting common stock converted automatically into one share of the Company’s common stock upon the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Public offering. In June 2015, the Company completed a public offering of its common stock. The offering included 24,150,000 newly issued shares of common stock sold by the Company (including 3,150,000 shares of common stock sold pursuant to the underwriters’ option to purchase additional shares) at an offering price of $30.75 per share for which the Company received total net proceeds of approximately $717.8 million.

The Tax Act, among other things, reduces the U.S. corporate income tax rate from 35% to 21% beginning in 2018, creates a new tax on GILTI and a BEAT, eliminates certain deductions, potentially limits deductions for interest expense and executive compensation, and imposes a mandatory one-time transition tax on the deemed repatriation of cumulative foreign earnings as of December 31, 2017. In accordance with SAB 118, the Company has made reasonable estimates of the effects of the Tax Act, including any state tax impacts of the Tax Act, and has recorded provisional amounts in the Company’s consolidated financial statements as of December 31, 2017. The Company recorded a provisional tax benefit for the impact of the Tax Act of approximately $88.0 million, which is primarily comprised of an income tax benefit of $121.6 million related to the remeasurement of federal net deferred tax assets and liabilities and an income tax expense of $33.6 million related to the mandatory one-time tax on the accumulated earnings of the Company’s foreign subsidiaries, which the Company plans to pay in installments over the allowable eight years. The final impact on the Company from the Tax Act may differ from the aforementioned reasonable estimate due to the complexity of the new legislation. Such differences could be material, due to, among other things, changes in interpretations of the Tax Act, future legislative action to address questions that arise because of the Tax Act, changes in accounting standards for income taxes or related interpretations in response to the Tax Act, or any updates or changes to estimates the Company has utilized to calculate the reasonable estimates. Pursuant to SAB 118, the Company is allowed a measurement period of up to one year after the enactment date of the Tax Act to finalize the accounting of the related tax impacts. The Company will continue to calculate the impact of the Tax Act and will record any resulting tax adjustments through the provision for income taxes in the period in which the adjustments are made. The components of deferred income taxes at December 31, 2017 and 2016 are as follows (in thousands): 2017 2016 Deferred Deferred Deferred Deferred Tax Tax Tax Tax Assets Liabilities Assets Liabilities Tax credit carryforwards $ 26,271 $ — $ 21,905 $ — Net operating loss carryforwards 24,158 — 34,666 — Deferred compensation 22,457 — 26,196 — Accrued expenses 13,340 — 8,478 — Other 936 — 1,699 — Impaired investment interest 568 — 810 — Customer relationships — 220,780 — 351,448 Other intangible assets — 53,716 — 38,728 Acquired technology — 53,255 — 100,691 Unremitted foreign earnings — 7,192 — 6,111 Trade names — 6,299 — 10,404 Property and equipment — 6,268 — 2,989 Deferred revenue — 247 — 3,166 Total 87,730 347,757 93,754 513,537 Valuation allowance (21,106 ) — (31,362 ) — Total $ 66,624 $ 347,757 $ 62,392 $ 513,537 At December 31, 2017 and 2016, the Company had accrued a deferred income tax liability for foreign withholding taxes of $7.2 million and $6.1 million, respectively, on unremitted earnings of its Canadian subsidiary. The Company recorded an income tax expense of $33.6 million related to the one-time transition tax on the deemed repatriation of its cumulative foreign earnings as of December 31, 2017. While no incremental U.S. federal taxes would be imposed on the actual distribution of those earnings as a result of the Tax Act, the Company had not accrued any deferred income taxes for withholding, foreign local or U.S. state income taxes on the unremitted earnings of its other foreign subsidiaries as those earnings are permanently reinvested. At December 31, 2017, the Company had domestic state net operating loss carryforwards of $29.7 million, which will begin to expire in 2020. At December 31, 2017, the Company had foreign net operating loss carryforwards of $85.8 million, of which $85.6 million can be carried forward indefinitely. The remaining $0.2 million will begin to expire in 2018. At December 31, 2017, the Company had tax credit carryforwards of $26.3 million relating to domestic and foreign jurisdictions, of which $23.4 million relate to domestic tax credits that are expected to be utilized before they begin to expire in 2018, $1.6 million relate to domestic tax credits that are not expected to be utilized before they begin to expire in 2022 and $1.3 million relate to foreign jurisdictions, of which $1.2 The Company has recorded valuation allowances of $21.1 million at December 31, 2017 related to certain foreign net operating loss carryforwards and tax credit carryforwards and $31.4 million at December 31, 2016 related to certain foreign net operating loss carryforwards and tax credit carryforwards. Of the $21.1 million valuation allowance recorded at December 31, 2017, $19.4 million relates to foreign net operating losses that do not expire. The change in the valuation allowance from 2016 to 2017 is primarily due to the utilization of foreign net operating losses, against which valuation allowances were previously recorded, during 2017. The following table summarizes the activity related to the Company’s unrecognized tax benefits for the years ended December 31, 2017 and 2016 (in thousands): Balance at December 31, 2015 $ 55,740 Increases related to current year tax positions 7,567 Increases related to prior tax positions 4,896 Increases related to acquired tax positions 453 Lapse in statute of limitation (5,629 ) Foreign exchange translation adjustment (39 ) Balance at December 31, 2016 62,988 Increases related to current year tax positions 7,576 Decreases related to prior tax positions (4,758 ) Settlements (6,012 ) Lapse in statute of limitation (2,809 ) Foreign exchange translation adjustment 561 Balance at December 31, 2017 $ 57,546 The Company accrued potential penalties and interest on the unrecognized tax benefits of $0.5 million and $(0.3) million during 2017 and 2016, respectively, and has recorded a total liability for potential penalties and interest, including penalties and interest related to acquired unrecognized tax benefits, of $3.6 million and $3.1 million at December 31, 2017 and 2016, respectively. The Company’s unrecognized tax benefits increased from 2015 to 2016 due to increases related to current and prior tax positions, offset partially by a lapse in the statute of limitations for certain domestic tax filings. The Company’s unrecognized tax benefits decreased from 2016 to 2017 due to settlements with federal and state tax authorities, a lapse in the statute of limitations for certain domestic tax filings and decreases in prior tax positions, offset partially by increased related to current tax positions. The Company believes it is reasonably possible that the amount of unrecognized tax benefits could decrease by $6.2 million due to the closure of tax statutes within the next 12 months. The Company’s unrecognized tax benefits as of December 31, 2017 relate to domestic and foreign taxing jurisdictions and are recorded in other long-term liabilities on the Company’s Consolidated Balance Sheet at December 31, 2017. The Company is subject to examination by tax authorities throughout the world, including such major jurisdictions as the U.S., Canada, United Kingdom, India, California, Connecticut and New York. In these major jurisdictions, the Company is no longer subject to examination by tax authorities prior to tax years ending 2010, 2013, 2014, 2015, 2012, 2012 and 2011, respectively. The Company’s U.S. federal income tax returns are currently under audit for the tax periods ended December 31, 2010 through 2012 and for the tax period ending December 31, 2015. The Company’s California state income tax returns are currently under audit for the tax periods ended December 31, 2012 through 2015. The Company’s United Kingdom tax returns are currently under audit for the tax periods ending December 31, 2014 through 2015.

In addition, the Credit Agreement has a revolving credit facility with a five year term available for borrowings by SS&C with $150 million in available commitments (“Revolving Credit Facility”), of which $149.1 million was available as of December 31, 2017. The Revolving Credit Facility had $94.0 million drawn on it as of December 31, 2016. The Revolving Credit Facility also contains a $25 million letter of credit sub-facility, of which $0.9 million and $0.6 million was drawn as of December 31, 2017 and 2016, respectively. On March 2, 2017, the Company entered into an amendment (the “Amendment”) to the Company’s Credit Agreement (“Amended Senior Secured Credit Agreement”). Pursuant to the Amendment, the highest (non-default) interest rate margin applicable to Term Loan A was reduced from LIBOR plus 2.75% to LIBOR plus 1.75%, and the highest (non-default) interest rate margin applicable to Term Loan B was reduced from LIBOR plus 3.25% to LIBOR plus 2.25%. The LIBOR “floor” was also amended for the Term Loan A and the Term Loan B to be 0%. No changes were made to the financial covenants, outstanding principal amounts or the scheduled amortization. The Amendment was evaluated in accordance with FASB Accounting Standards Codification 470-50, Debt-Modifications and Extinguishments , for modification and extinguishment accounting. The Company accounted for the debt re-pricing as a debt modification with respect to amounts that remained obligations of the same lender in the syndicate with minor changes in cash flows and as a debt extinguishment with respect to amounts that were obligations of lenders that exited the syndicate or remained in the syndicate but experienced a change in cash flows of greater than 10%. The Company is required to make scheduled quarterly payments of approximately 0.25% of the remaining principal amount of the Term B-1 Loan and Term B-2 Loan, with the balance due and payable on the seventh anniversary of its incurrence. The Company is required to make scheduled quarterly payments of 1.25% of the original principal amount of the Term A-1 Loan and Term A-2 Loan until September 30, 2017 and quarterly payments of 2.50% of the original principal amount of the Term A-1 Loan and Term A-2 Loan from December 31, 2017 until June 30, 2020 with the balance due and payable on the fifth anniversary of the incurrence thereof. No amortization is required under the Revolving Credit Facility. The Company’s obligations under the Term Loans are guaranteed by (i) Holdings and each of its existing and future U.S. wholly-owned restricted subsidiaries, in the case of the Term B-1 Loan and the Revolving Credit Facility and (ii) Holdings, SS&C and each of its existing and future wholly-owned restricted subsidiaries, in the case of the Term A-1 Loan, the Term A-2 Loan and the Term B-2 Loan. The obligations of the U.S. loan parties under the Amended Senior Secured Credit Agreement are secured by substantially all of the assets of such persons (subject to customary exceptions and limitations), including a pledge of all of the capital stock of substantially all of the U.S. wholly-owned restricted subsidiaries of such persons (with customary exceptions and limitations) and 65% of the capital stock of certain foreign restricted subsidiaries of such persons (with customary exceptions and limitations). All obligations of the non-U.S. loan parties under the Amended Senior Secured Credit Agreement are secured by substantially all of Holdings’ and the other guarantors’ assets (subject to customary exceptions and limitations), including a pledge of all of the capital stock of substantially all of Holdings’ wholly-owned restricted subsidiaries (with customary exceptions and limitations). The Amended Senior Secured Credit Agreement includes negative covenants that, among other things and subject to certain thresholds and exceptions, limit the Company’s ability and the ability of its restricted subsidiaries to incur debt or liens, make investments (including in the form of loans and acquisitions), merge, liquidate or dissolve, sell property and assets, including capital stock of its subsidiaries, pay dividends on its capital stock or redeem, repurchase or retire its capital stock, alter the business the Company conducts, amend, prepay, redeem or purchase subordinated debt, or engage in transactions with its affiliates. The Amended Senior Secured Credit Agreement also contains customary representations and warranties, affirmative covenants and events of default, subject to customary thresholds and exceptions. In addition, the Amended Senior Secured Credit Agreement contains a financial covenant for the benefit of the Revolving Credit Facility as well as the Term A-1 Loan and the Term A-2 Loan, requiring the Company to maintain a consolidated net senior secured leverage ratio. In addition, under the Amended Senior Secured Credit Agreement, certain defaults under agreements governing other material indebtedness could result in an event of default under the Amended Senior Secured Credit Agreement, in which case the lenders could elect to accelerate payments under the Amended Senior Secured Credit Agreement and terminate any commitments they have to provide future borrowings. As of December 31, 2017, the Company was in compliance with the financial and non-financial covenants. Senior Notes On July 8, 2015, in connection with the acquisition of Advent, the Company issued $600.0 million aggregate principal amount of 5.875% Senior Notes due 2023 (“Senior Notes”). The Senior Notes are guaranteed by SS&C and each of the Company’s wholly-owned domestic subsidiaries that borrows or guarantees obligations under the Amended Senior Secured Credit Agreement. The guarantees are full and unconditional and joint and several. The Senior Notes are unsecured senior obligations that are equal in right of payments to all existing and future senior debt, including the Amended Senior Secured Credit Agreement. On April 20, 2016, the Company commenced an offer to exchange for the Senior Notes, new notes identical in all material respects to the Senior Notes, except that the new notes have been registered under the Securities Act of 1933. The exchange offer expired on May 18, 2016 and 100% of the Senior Notes were exchanged for the new notes. At any time after July 15, 2018, the Company may redeem some or all of the Senior Notes, in whole or in part, at the redemption prices set forth in the indenture governing the Senior Notes plus accrued and unpaid interest to the redemption date. At any time on or before July 15, 2018, the Company may redeem all or any portion of the notes at 100% of their principal amount, plus a “make whole” premium calculated pursuant to the indenture governing the Senior Notes, plus accrued and unpaid interest to, but excluding, the redemption date. In addition, prior to July 15, 2018, the Company may redeem up to 35% of the aggregate principal amount of the Senior Notes at a redemption price equal to 105.875% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net proceeds of one or more equity offerings. The indenture governing the Senior Notes contains a number of covenants that restrict, subject to certain thresholds and exceptions, the Company’s ability and the ability of its restricted subsidiaries to incur debt or liens, make certain investments, pay dividends, repurchase or redeem subordinated debt, dispose of certain assets, engage in mergers or acquisitions or engage in transactions with its affiliates. Any event of default under the Amended Senior Secured Credit Agreement that leads to an acceleration of those amounts due also results in a default under the indenture governing the Senior Notes. As of December 31, 2017, there were $600.0 million in principal amount of Senior Notes outstanding. Debt issuance costs In connection with the Amended Senior Secured Credit Agreement and the Senior Notes, the Company capitalized an aggregate of $45.8 million in financing costs. Capitalized financing costs of $8.3 million, $8.5 million and $6.4 million were amortized to interest expense in the years ended December 31, 2017, 2016 and 2015, respectively, and the Company amortized to interest expense $2.3 million, $2.2 million and $1.8 million of the original issue discount associated with the Amended Senior Secured Credit Agreement and Prior Facility for the years ended December 31, 2017, 2016 and 2015, respectively. The unamortized balance of capitalized financing costs is included in long-term debt in the Company’s Consolidated Balance Sheets. Loss on extinguishment of debt The Company recorded a $2.3 million loss on extinguishment of debt in 2017 in connection with the Amendment. The loss on early extinguishment of debt includes the write-off of a portion of the unamortized capitalized financing fees related to the Credit Agreement for amounts accounted for as a debt extinguishment, as well as new financing fees related to the Amendment for amounts accounted for as a debt modification. The Company recorded a $30.4 million loss on extinguishment of debt in 2015 in connection with the repayment and termination of its Prior Facility. The loss on early extinguishment of debt includes the write-off of a portion of the unamortized capitalized financing costs and the unamortized original issue discounts related to the Prior Facility for amounts accounted for as a debt extinguishment, as well as a portion of the financing costs related to the Credit Agreement for amounts accounted for as a debt modification. Future maturities of debt At December 31, 2017, annual maturities of long-term debt during the next five years and thereafter are as follows (in thousands): Year ending December 31, 2018 $ 37,863 2019 37,863 2020 181,613 2021 12,863 2022 and thereafter 1,821,973 Total $ 2,092,175

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7—Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The authoritative guidance relating to fair value measurements and disclosure establishes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. ● Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. ● Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, including interest rates, yield curves and credit risks, or inputs that are derived principally from or corroborated by observable market data through correlation. ● Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. As of December 31, 2017 and 2016, the Company did not have any significant nonfinancial assets and nonfinancial liabilities that are measured at fair value on a non-recurring basis. Recurring Fair Value Measurements The Company did not have any material financial assets or liabilities that were measured at fair value as of December 31, 2017 and 2016. Fair value of debt The carrying amounts and fair values of financial instruments are as follows (in thousands): December 31, 2017 December 31, 2016 Carrying Fair Carrying Fair Amount Value Amount Value Financial liabilities: Senior secured credit facilities $ 1,492,175 $ 1,500,761 $ 1,865,625 $ 1,887,043 5.875% senior notes due 2023 600,000 631,313 600,000 619,500 Senior secured credit facilities, revolving portion — — 94,000 93,883 The above fair values, which are Level 2 liabilities, were computed based on comparable quoted market prices. The fair values of cash, accounts receivable, net, short-term borrowings, and accounts payable approximate the carrying amounts due to the short-term maturities of these instruments.

The customer relationships are amortized over approximately fourteen years and the completed technology is amortized over approximately two years, in each case the estimated lives of the assets. The remainder of the purchase price was allocated to goodwill and is tax deductible. Citigroup’s Alternative Investor Services Business On March 11, 2016, the Company purchased all of the outstanding stock of Citigroup’s Alternative Investor Services business, which includes Hedge Fund Services and Private Equity Fund Services (“Citigroup AIS”), for approximately $296.4 million, plus the costs of effecting the transaction and the assumption of certain liabilities. Citigroup AIS is a leading provider of hedge fund and private equity fund administration services. The net assets and results of operations of Citigroup AIS have been included in the Company’s Consolidated Financial Statements from March 11, 2016. The fair value of the intangible assets, consisting of customer relationships and completed technology, was determined using the income approach and cost savings method. Specifically, the excess earnings method was utilized for the customer relationships and the cost savings method was utilized for the completed technology. The customer relationships are amortized each year based on the ratio that the projected cash flows for the intangible assets bear to the total of current and expected future cash flows for the intangible assets. Completed technology is amortized based on a straight-line basis. The customer relationships are amortized over approximately thirteen years and completed technology is amortized over approximately four years, in each case the estimated lives of the assets. The remainder of the purchase price was allocated to goodwill and is tax deductible. The following summarizes the preliminary allocation of the purchase price for the 2017 acquisition of CommonWealth and the final allocation of the purchase price for the 2016 acquisitions of Conifer, GFS and Citigroup AIS (in thousands): CommonWealth Conifer GFS Citigroup AIS Accounts receivable $ 871 $ 2,990 $ 6,118 $ 58,509 Fixed assets 141 2,960 356 103 Other assets 176 1,243 465 1,985 Acquired client relationships and contracts 6,660 40,500 37,700 124,600 Completed technology — — 8,700 44,600 Trade names 78 — — — Goodwill 10,677 43,772 22,437 78,691 Deferred revenue — (103 ) 43 (3,841 ) Deferred income taxes (1,822 ) (3 ) — — Other liabilities assumed (395 ) (5,450 ) (4,037 ) (8,228 ) Consideration paid, net of cash acquired $ 16,386 $ 85,909 $ 71,782 $ 296,419 Additionally, the Company acquired Modestspark in October 2017 for approximately $2.8 million and Salentica in October 2016 for approximately $2.0 million. The consideration paid, net of cash acquired for Conifer and GFS includes purchase price adjustments totaling $1.8 million, which was received during the first quarter of 2017. This amount is reflected in “Cash paid for business acquisitions, net of cash acquired” for the year ended December 31, 2017 on the Company’s Consolidated Statement of Cash Flows. The consideration paid, net of cash acquired for Citigroup AIS includes purchase price adjustments totaling $20.8 million, which was received during the third and fourth quarters of 2016. This amount is reflected in “Cash paid for business acquisitions, net of cash acquired” for the year ended December 31, 2016 on the Company’s Consolidated Statement of Cash Flows. The fair value of acquired accounts receivable balances approximates the contractual amounts due from acquired customers, except for approximately $0.4 million and $1.7 million of contractual amounts that are not expected to be collected as of the acquisition date and that were also reserved by the companies acquired – Conifer and Citigroup AIS, respectively. The goodwill associated with each of the transactions above is a result of expected synergies from combining the operations of businesses acquired with the Company and intangible assets that do not qualify for separate recognition, such as an assembled workforce. The following unaudited pro forma condensed consolidated results of operations are provided for illustrative purposes only and assume that the acquisitions of CommonWealth and Modestspark occurred on January 1, 2016 and Conifer, GFS, Salentica and Citigroup AIS occurred on January 1, 2015. This unaudited pro forma information (in thousands, except per share data) should not be relied upon as being indicative of the historical results that would have been obtained if the acquisitions had actually occurred on that date, nor of the results that may be obtained in the future.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, collectability of accounts receivable, costs to complete certain contracts, valuation of acquired assets and liabilities, valuation of stock options, income tax accruals and the value of deferred tax assets and liabilities. Estimates are also used to determine the remaining economic lives and carrying value of fixed assets, goodwill and intangible assets. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. All significant accounts, transactions and profits between the consolidated companies have been eliminated in consolidation. Unconsolidated investments in entities over which the Company does not have control but has the ability to exercise influence over operating and financial policies, if any, are accounted for under the equity method of accounting. Earnings and losses from such investments are recorded on a pre-tax basis, if any. Certain prior year balances have been reclassified to conform to the current year presentation. Such reclassifications did not affect total revenues, operating income or net income.
Revenue Recognition	Revenue Recognition The Company’s payment terms for perpetual software licenses typically require that the total fee be paid upon signing of the contract. Maintenance services and term license fees are typically due in full at the beginning of each annual period. Professional services and software-enabled services are typically due and payable monthly in arrears. Normally, the Company’s arrangements do not provide for any refund rights, and payments are not contingent on specific milestones or customer acceptance conditions. For arrangements that do contain such provisions, the Company defers revenue until the rights or conditions have expired or have been met. Unbilled accounts receivable primarily relate to professional services and software-enabled services revenue that has been earned as of month end but is not invoiced until the subsequent month, and to software license revenue that has been earned and is realizable but not invoiced to clients until future dates specified in the client contract. Deferred revenue consists of billings or payments received related to product delivery, maintenance and other services, which have been paid by customers prior to the recognition of revenue. Deferred revenue relates primarily to cash received for maintenance and term license contracts in advance of services being performed over the contractual term. Software-enabled Services Revenue The Company primarily offers software-enabled outsourcing services in which the Company utilizes its own software to offer comprehensive fund administration services for alternative investment managers, including fund manager services, transfer agency services, funds-of-funds services, tax processing and accounting. The Company also offers subscription-based on-demand software applications that are managed and hosted at the Company’s facilities. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under these arrangements, the client does not have the right to take possession of the software, rather, the Company agrees to provide access to its applications, remote use of its equipment to process transactions, access to client’s data stored on its equipment, and connectivity between its environment and the client’s computing systems. Software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments, and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. The Company recognizes software-enabled services revenues on a monthly basis as the software-enabled services are provided and when persuasive evidence of an arrangement exists, the price is fixed or determinable and collectability is reasonably assured. The Company does not recognize any revenue before services are performed. Certain contracts contain additional fees for increases in market value, pricing and trading activity. Revenues related to these additional fees are recognized in the month in which the activity occurs based upon the Company’s summarization of account information and trading volume. Maintenance and Term Licenses Revenue Maintenance agreements generally require the Company to provide technical support and software updates (on a when-and-if-available basis) to its clients. Such services are generally provided under one-year renewable contracts. Maintenance revenues are recognized ratably over the term of the maintenance agreement. The Company also sells term licenses ranging from one to seven years, many of which include bundled maintenance services. For those arrangements with bundled maintenance services, vendor-specific objective evidence (“VSOE”) does not exist for the maintenance element and therefore the total fee is recognized ratably over the contractual term of the arrangement. Perpetual Licenses Revenue The Company follows the principles of accounting standards relating to software revenue recognition, which provide guidance on applying GAAP in recognizing revenue on software transactions. Accounting standards require that revenue recognized from software transactions be allocated to each element of the transaction based on the relative fair values of the elements, such as software products, specified upgrades, enhancements, post-contract client support, installation or training. The determination of fair value is based upon VSOE. The Company recognizes perpetual licenses revenues allocated to software products and enhancements generally upon delivery of each of the related products or enhancements, assuming all other revenue recognition criteria are met. In the rare occasion that a perpetual license agreement includes the right to a specified upgrade or product, the Company defers all revenues under the arrangement until the specified upgrade or product is delivered, since typically VSOE does not exist to support the fair value of the specified upgrade or product. The Company generally recognizes revenue from sales of software or products including proprietary software upon product shipment and receipt of a signed contract, provided that collection is probable and all other revenue recognition criteria are met. The Company sells perpetual software licenses in conjunction with professional services for installation and maintenance. For these arrangements, the total contract value is attributed first to the maintenance arrangement based on its fair value, which is derived from stated renewal rates. The contract value is then attributed to professional services based on estimated fair value, which is derived from the rates charged for similar services provided on a stand-alone basis. The Company’s software license agreements generally do not require significant modification or customization of the underlying software, and, accordingly, implementation services provided by the Company are not considered essential to the functionality of the software. The remainder of the total contract value is then attributed to the software license based on the residual method. The Company occasionally enters into license agreements requiring significant customization of the Company’s software. The Company accounts for the license fees under these agreements on the percentage-of-completion basis. This method requires estimates to be made for costs to complete the agreement utilizing an estimate of development man-hours remaining. Revenue is recognized each period based on the hours incurred to date compared to the total hours expected to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs may be revised. Such revisions are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are determined on a contract-by-contract basis, and are made in the period in which such losses are first estimated or determined. Professional Services Revenue The Company provides consulting and training services to its clients. Revenues for such services are generally recognized over the period during which the services are performed. The Company typically charges for professional services on a time-and-materials basis. However, some contracts are for a fixed fee. For the fixed-fee arrangements, an estimate is made of the total hours expected to be incurred to complete the project. Due to uncertainties inherent in the estimation process, it is at least reasonably possible that completion costs may be revised. Such revisions are recognized in the period in which the revisions are determined. Revenues are recognized each period based on the hours incurred to date compared to the total hours expected to complete the project.
Research and Development	Research and Development Research and development costs associated with computer software are charged to expense as incurred. Capitalization of internally developed computer software costs in the case of software to be sold begins upon the establishment of technological feasibility based on a working model. Capitalization of internally developed computer software costs in the case of internal use software begins when management authorizes and commits funding to a project and the preliminary design stage has been completed. Net capitalized software costs of $12.1 million and $8.8 million are included in the December 31, 2017 and 2016 Consolidated Balance Sheets, respectively, under “Intangible and other assets”. The Company’s policy is to amortize these costs upon a product’s general release to the client. Amortization of capitalized software costs is calculated by the greater of (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product, including the period being reported on, typically two to five years. It is reasonably possible that those estimates of anticipated future gross revenues, the remaining estimated economic life of the product, or both could be reduced significantly due to competitive pressures. Amortization expense related to capitalized software development costs was $5.4 million, $3.5 million, and $2.4 million for each of the years ended December 31, 2017, 2016, and 2015, respectively.
Stock-based Compensation	Stock-based Compensation Using the fair value recognition provisions of relevant accounting literature, stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the appropriate service period. Determining the fair value of stock-based awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of the Company’s stock price. Differences between actual results and these estimates could have a material effect on the Company’s financial results. A deferred income tax asset is recorded over the vesting period as stock compensation expense is recorded for non-qualified option awards. The realizability of the deferred tax asset is ultimately based on the actual value of the stock-based award upon exercise. If the actual value is lower than the fair value determined on the date of grant, then there would be an income tax expense for the portion of the deferred tax asset that is not realizable.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with the relevant accounting literature. An asset and liability approach is used to recognize deferred tax assets and liabilities for the future tax consequences of items that are recognized in the Company’s financial statements and tax returns in different years. A valuation allowance is established against net deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the net deferred tax assets will not be realized. The Company accounts for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was enacted into law and the new legislation contains several significant changes to U.S. tax law that affected the Company, including a one-time mandatory transition tax on accumulated foreign earnings and a reduction of the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate effective January 1, 2018, among others. The Tax Act also adds new provisions including limitations on the deductibility of interest expense and executive compensation, a minimum tax on global intangible low-taxed income (“GILTI”) and the base erosion anti-abuse tax (“BEAT”). The Company is required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, re-measuring the Company’s U.S. deferred tax assets and liabilities as well as reassessing the net realizability of the Company’s deferred tax assets and liabilities. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. Under U.S.GAAP, the Company can make an accounting policy election to either treat taxes due on the GILTI as a current period expense, or factor such amounts into our measurement of deferred taxes. The Company has elected the deferred method and recorded a reasonable estimate of $ 6.7 million related to GILTI. Income Tax Accounting Implications of the Tax Cuts and Jobs Act items to be incomplete due to the forthcoming guidance and the Company’s ongoing analysis of final year-end data and tax positions. The Company’s initial accounting for the GILTI tax is provisional under SAB 118 and is incomplete because the Company is still refining its measurement methodology. The Company is currently assessing the impact of other certain provisions, including the base erosion anti-abuse tax (“BEAT”), which does not apply to 2017. Additionally, the Company has considered the impact of limitations on the deductibility of interest expense and executive compensation on the realizability of its deferred tax assets and made a reasonable estimate that these changes do not significantly impact tax expense. The
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid marketable securities with original maturities of three months or less at the date of acquisition to be cash equivalents. The Company did not hold any cash equivalents at December 31, 2017 and 2016.
Restricted Cash	Restricted Cash Restricted cash includes monies held by a bank as security for letters of credit issued due to lease requirements for office space. The letters of credit are expected to be renewed within the next twelve months, and as such, the restricted cash is classified as a current asset on the Consolidated Balance Sheets.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation of property, plant and equipment is calculated using a combination of straight-line and accelerated methods over the estimated useful lives of the assets as follows: Description Useful Life Land — Buildings and improvements 40 years Equipment and software 3-5 years Furniture and fixtures 7-10 years Leasehold improvements Shorter of lease term or estimated useful life Depreciation expense for the years ended December 31, 2017, 2016 and 2015 was $25.9 million, $23.7 million and $18.9 million, respectively. Maintenance and repairs are expensed as incurred. The costs of sold or retired assets are removed from the related asset and accumulated depreciation accounts and any gain or loss is included in the Statements of Comprehensive Income (Loss).
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company tests goodwill annually for impairment as of December 31 st The following table summarizes changes in goodwill (in thousands): Balance at December 31, 2015 $ 3,549,212 2016 acquisitions 148,235 Adjustments to prior acquisitions (4,787 ) Effect of foreign currency translation (39,927 ) Balance at December 31, 2016 $ 3,652,733 2017 acquisitions 13,328 Adjustments to prior acquisitions (621 ) Effect of foreign currency translation 42,383 Balance at December 31, 2017 $ 3,707,823 Customer relationships, completed technology, trade names and other identifiable intangible assets are amortized over lives ranging from three to 17 years based on the ratio that cash flows for the intangible asset bear to the total of expected future cash flows for the intangible asset. Amortization expense associated with customer relationships, completed technology and other amortizable intangible assets was $205.9 million, $201.5 million and $129.5 million for the years ended December 31, 2017, 2016 and 2015, respectively. A summary of the components of intangible assets is as follows (in thousands): December 31, 2017 2016 Customer relationships $ 1,665,814 $ 1,645,515 Completed technology 550,921 545,273 Trade names 61,093 60,128 Other 2,782 2,709 Total intangible assets 2,280,610 2,253,625 Less: accumulated amortization (938,833 ) (720,930 ) Total intangible assets, net $ 1,341,777 $ 1,532,695 Total estimated amortization expense, related to intangible assets, for each of the next five years, as of December 31, 2017, is expected to approximate (in thousands): Year Ending December 31, 2018 $ 211,256 2019 193,281 2020 174,492 2021 134,941 2022 118,670 Thereafter 509,137 Total $ 1,341,777
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company evaluates the recoverability of its long-lived assets when there is evidence that events or changes in circumstances have made recovery of the assets’ carrying value unlikely. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. The Company has identified no such impairment losses in the years ended December 31, 2017 and 2016.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, marketable securities, and trade receivables. The Company has cash investment policies that limit investments to investment grade securities. Concentrations of credit risk, with respect to trade receivables, are limited due to the fact that the Company’s client base is highly diversified. As of December 31, 2017 and 2016, the Company had no significant concentrations of credit.
International Operations and Foreign Currency	International Operations and Foreign Currency The functional currency of each foreign subsidiary is generally the local currency. Accordingly, assets and liabilities of foreign subsidiaries are translated to U.S. dollars at period-end exchange rates, and capital stock accounts are translated at historical rates. Revenues and expenses are translated using the average rates during the period. The resulting translation adjustments are excluded from net earnings and accumulated as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included within other (expense) income in the Consolidated Statements of Comprehensive Income (Loss) in the periods in which they occur.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Items defined as comprehensive income (loss), such as foreign currency translation adjustments, are separately classified in the Consolidated Financial Statements. The accumulated balance of other comprehensive income (loss) is reported separately from retained earnings and additional paid-in capital in the equity section of the Consolidated Balance Sheets. Total comprehensive income (loss) consists of net income (loss) and other accumulated comprehensive income (loss) disclosed in the equity section of the Consolidated Balance Sheets.
Treasury Stock	Treasury Stock Treasury stock purchases are accounted for under the cost method and are included as a deduction from equity in the Stockholders’ Equity section of the Consolidated Balance Sheets. Under the cost method, the price paid for the stock is charged to the treasury stock account.
Basic and Diluted Earnings per Share	Basic and Diluted Earnings per Share Earnings per share (“EPS”) is calculated in accordance with the relevant standards. Basic EPS includes no dilution and is computed by dividing income available to the Company’s common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of stock options, stock appreciation rights (“SARs”) and restricted stock units (“RSUs”) and restricted stock awards (“RSAs”) using the treasury stock method. Common equivalent shares are excluded from the computation of diluted earnings per share if the effect of including such common equivalent shares is anti-dilutive because their total assumed proceeds exceed the average fair value of common stock for the period. The Company has two classes of common stock, each with identical participation rights to earnings and liquidation preferences, and therefore the calculation of EPS as described above is identical to the calculation under the two-class method. The following table sets forth the computation of basic and diluted EPS (in thousands, except per share amounts): Year Ended December 31, 2017 2016 2015 Net income $ 328,864 $ 130,996 $ 42,862 Shares: Weighted average common shares outstanding — used in calculation of basic EPS 204,923 200,252 182,196 Weighted average common stock equivalents — options and restricted shares 6,709 5,541 8,700 Weighted average common and common equivalent shares outstanding — used in calculation of diluted EPS 211,632 205,793 190,896 Earnings per share - Basic $ 1.60 $ 0.65 $ 0.24 Earnings per share - Diluted $ 1.55 $ 0.64 $ 0.22 Weighted average stock options, SARs, RSUs and RSAs representing 10,641,582, 14,094,402 and 7,001,656 shares were outstanding for the years ended December 31, 2017, 2016 and 2015, respectively, but were not included in the computation of diluted EPS because the effect of including them would be anti-dilutive.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Subsequent to the issuance of ASU 2014-09, the FASB has issued the following updates: ASU 2016-08, Revenue from Contracts with Customers (Topic 606) – Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and Licensing Revenue from Contracts with Customers (Topic 606) – Narrow-Scope Improvements and Practical Expedients Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), and Revenue from contracts with Customers (Topic 606) Income Statement-Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from contracts with Customers (Topic 606) The Company will adopt the new revenue standard using the modified retrospective approach when it becomes effective for the Company in the first quarter of 2018. Once adopted, the Company will recognize the license component of term license arrangements upfront and the associated maintenance component will continue to be recognized over the contract period. Under the current revenue standard, for the majority of the Company’s term license arrangements which are bundled with maintenance services, both the term license and maintenance revenues are recognized ratably over the contract period. Upon adoption, the Company will record a one-time pre-tax cumulative effect adjustment of approximately $60 million to increase retained earnings. This amount represents the license component of existing term license arrangements, both in deferred revenue and yet to be billed, which has not yet been recognized and will never be recognized in the Company’s Consolidated Statements of Comprehensive Income (Loss) as a result of adopting the standard. The Company expects revenue recognition for the Company’s other revenue streams to remain materially consistent with its historical revenue recognition practices.
