Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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. 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.
	Revenue Recognition
	The Company’s payment terms for software licenses typically require that the total fee be paid upon signing of the contract. Maintenance services are typically due in full at the beginning of the maintenance 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 relates 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 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 contracts in advance of services being performed over the contractual term.
	Software-enabled Services Revenue
	The Company’s software-enabled services arrangements make its software applications available to its clients for processing of transactions. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under the 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 non-cancelable 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 pervasive 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.
	Software 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 vendor-specific objective evidence (“VSOE”). The Company recognizes software 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 software 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 also sells term licenses ranging from one to seven years, some of which include bundled maintenance services. For those arrangements with bundled maintenance services, VSOE does not exist for the maintenance element and therefore the total fee is recognized ratably over the contractual term of the arrangement. The Company classifies revenues from bundled term license arrangements as both software licenses and maintenance revenues by allocating a portion of the revenues from the arrangement to maintenance revenues and classifying the remainder in software licenses revenues. The Company uses its renewal rates for maintenance under perpetual license agreements for the purpose of determining the portion of the arrangement fee that is classified as maintenance revenues.
	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.
	Maintenance Revenue Agreements
	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.
	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 begins upon the establishment of technological feasibility based on a working model. Net capitalized software costs of $4.2 million and $3.5 million are included in the December 31, 2014 and 2013 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 $1.8 million, $1.0 million, and $0.5 million for each of the years ended December 31, 2014, 2013, and 2012, 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, expected volatility of the Company’s stock price, and the number of awards expected to be forfeited. 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 could be an income tax expense for the portion of the deferred tax asset that is not realizable.
	Other Income (Expense), Net
	Other income, net for 2014 consists primarily of foreign currency transaction gains of $2.9 million. The gains were partially offset by an increase of $0.4 million to the contingent consideration liability for the acquisition of Prime Management Limited (“Prime”). Other income, net for 2013 consists primarily of foreign currency transaction gains of $3.4 million. Other expense, net for 2012 consists primarily of foreign currency transaction losses of $12.4 million and a loss of $3.8 million recorded on foreign currency contracts associated with the acquisition of GlobeOp Financial Services, S.A. (“GlobeOp”), which is discussed further in Note 12. These losses were partially offset by a reduction of the Company’s remaining contingent consideration liability associated with the BenefitsXML, Inc. acquisition from $0.3 million to $0.
	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.
	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, 2014 and 2013.
	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 letter of credits 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 Sheet. Additionally, movements of restricted cash are included in other investing activities on the Consolidated Statement of Cash Flows.
	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, 2014, 2013 and 2012 was $14.3 million, $14.7 million and $10.7 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 other income (expense), net.
	Goodwill and Intangible Assets
	The Company tests goodwill annually for impairment as of December 31st (and in interim periods if certain events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount). The Company has completed the required impairment tests for goodwill and has determined that no impairment existed as of December 31, 2014 or 2013. The first step of the impairment analysis, which is based on our reporting unit structure, indicated that the fair value significantly exceeded the carrying value at December 31, 2014. There were no other indefinite-lived intangible assets as of December 31, 2014 or 2013.
	The following table summarizes changes in goodwill (in thousands):
	Balance at December 31, 2012		1,559,607
	2013 acquisitions		910
	Adjustments to previous acquisitions		(202	)

	2014 acquisition		66,511
	Effect of foreign currency translation		(34,670	)
	Balance at December 31, 2014	$	1,573,227
	Completed technology and other identifiable intangible assets are amortized over lives ranging from three to 17 years based on the ratio that current cash flows for the intangible asset bear to the total of current and expected future cash flows for the intangible asset. Amortization expense associated with completed technology and other amortizable intangible assets was $83.7 million, $84.1 million and $64.6 million for the years ended December 31, 2014, 2013 and 2012, respectively.

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, 2014 and 2013.
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, 2014 and 2013, the Company had no significant concentrations of credit.
International Operations and Foreign Currency
The functional currency of each foreign subsidiary is 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 income (expense) in the results of operations in the periods in which they occur.
Comprehensive Income
Items defined as comprehensive income, such as foreign currency translation adjustments, are separately classified in the financial statements. The accumulated balance of other comprehensive income is reported separately from retained earnings and additional paid-in capital in the equity section of the Consolidated Balance Sheet. Total comprehensive income consists of net income and other accumulated comprehensive income disclosed in the equity section of the Consolidated Balance Sheet.
Recent Accounting Pronouncements
In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). This ASU establishes specific guidance to an organization’s management on their responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. The provisions of ASU 2014-15 are effective for interim and annual periods beginning after December 15, 2016. This ASU is not expected to have an impact on the Company’s financial position, results of operations or cash flows.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The objective of ASU 2014-09 is to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of ASU 2014-09 are effective for interim and annual periods beginning after December 15, 2016. The Company is currently evaluating the impact of this standard on its financial position, results of operations and cash flows.
In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740) – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). The objective of ASU 2013-11 is to end some inconsistent practices with regard to the presentation on the balance sheet of unrecognized tax benefits. ASU 2013-11 is effective for financial statement periods beginning after December 15, 2013, with early adoption permitted. The adoption of this standard in the first quarter of 2014 did not have a material impact on the Company’s financial position, results of operations or cash flows.
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 and restricted stock 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 weighted average common shares used in the computation of basic and diluted EPS (in thousands):
	Year Ended December 31,
	2014			2013			2012
Weighted average common shares outstanding — used in calculation of basic EPS		83,314			81,195			78,321
Weighted average common stock equivalents — options and restricted shares		4,017			4,421			4,567
Weighted average common and common equivalent shares outstanding — used in calculation of diluted EPS		87,331			85,616			82,888
Options to purchase 1,841,840, 133,598 and 703,446 shares were outstanding for the years ended December 31, 2014, 2013 and 2012, respectively, but were not included in the computation of diluted EPS because the effect of including the options would be anti-dilutive.

	At December 31, 2014 and 2013, the Company had accrued deferred income taxes of $5.7 million on its unremitted earnings of its Canadian subsidiary. The Company had not accrued deferred income taxes on unremitted earnings of any of its other non-U.S. subsidiaries. The earnings were approximately $76.8 million as of December 31, 2014. It is not practicable to estimate the amount of tax that would be payable upon repatriation of the earnings as such earnings are expected to be permanently reinvested overseas.
	At December 31, 2014, the Company had foreign net operating loss carryforwards of $46.3 million, of which $46.1 million can be carried forward indefinitely. The remaining $0.2 million will begin to expire in 2016. The Company had domestic state net operating loss carryforwards of $0.1 million, which will begin to expire in 2031.
	At December 31, 2014, the Company had tax credit carryforwards of $4.8 million relating to domestic and foreign jurisdictions, of which $3.8 million relate to domestic tax credits that are expected to be utilized before they begin to expire in 2015 and $1.0 million relate to alternative minimum tax credit carryforwards at the Company’s India operations that are expected to be utilized before they begin to expire in 2022.
	The Company has recorded valuation allowances of $12.6 million at December 31, 2014 related to certain foreign net operating loss carryforwards and $5.0 million at December 31, 2013 related to certain foreign net operating loss and tax credit carryforwards. The change in the valuation allowance is primarily due to a valuation allowance recorded on acquired net operating loss carryforwards.
	The Company operates under tax holidays in some foreign jurisdictions, which begin to expire in 2017. The availability of the tax holidays are subject to fulfillment of certain conditions. The impact of the tax holidays decreased foreign taxes by $0.6 million, which had a benefit of $0.01 per share (diluted) for the year ended December 31, 2014.
	The following table summarizes the activity related to the Company’s unrecognized tax benefits for the years ended December 31, 2014 and 2013 (in thousands):

The Company’s unrecognized tax benefits as of December 31, 2014 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, 2014.
The Company is subject to examination by tax authorities throughout the world, including such major jurisdictions as the U.S., Canada, United Kingdom, India, Connecticut and New York. In these major jurisdictions, the Company is no longer subject to examination by tax authorities for years prior to 2009, 2010, 2011, 2011, 2009 and 2009, respectively. The Company’s U.S. federal income tax returns are currently under audit for the tax periods ended December 31, 2009 through 2013. The Company’s Connecticut and New York state income tax returns are currently under audit for the tax periods ended December 31, 2009 through 2011.

	The carrying value of the Company’s credit facilities approximate fair value given the variable rate nature of the debt, and as such, are a Level 2 liability (as discussed in Note 8).
	Capitalized financing costs of $4.4 million, $4.4 million and $2.6 million were amortized to interest expense in the years ended December 31, 2014, 2013 and 2012, respectively, and the Company amortized to interest expense $1.4 million, $1.4 million and $0.8 million of the original issue discount associated with the credit agreement (“Credit Agreement”) for the years ended December 31, 2014, 2013 and 2012, respectively. The unamortized balance of capitalized financing costs is included in intangible and other assets in the Company’s Consolidated Balance Sheet. Additionally, the Company had $4.4 million in losses on extinguishment of debt associated with the repayment of the prior senior credit facility in 2012, as shown on the Company’s Consolidated Statements of Comprehensive Income and described below.
	Credit facility. On March 14, 2012, Holdings entered into a Credit Agreement with SS&C and SS&C Technologies Holdings Europe S.A.R.L., an indirect wholly-owned subsidiary of SS&C (“SS&C Sarl”), as the borrowers. The Credit Agreement has four tranches of term loans: (i) a $0 term A-1 facility with a five and one-half year term for borrowings by SS&C, (ii) a $325 million term A-2 facility with a five and one-half year term for borrowings by SS&C Sarl, (iii) a $725 million term B-1 facility with a seven year term for borrowings by SS&C and (iv) a $75 million term B-2 facility with a seven year term for borrowings by SS&C Sarl. In addition, the Credit Agreement had a $142 million bridge loan facility, of which $31.6 million was immediately drawn, with a 364-day term available for borrowings by SS&C Sarl and has a revolving credit facility with a five and one-half year term available for borrowings by SS&C with $100 million in commitments. The revolving credit facility contains a $25 million letter of credit sub-facility and a $20 million swingline loan sub-facility. The bridge loan was repaid in July 2012 and is no longer available for borrowing.
	The term loans and the revolving credit facility bear interest, at the election of the borrowers, at the base rate (as defined in Credit Agreement) or LIBOR, plus the applicable interest rate margin for the credit facility. The term A loans and the revolving credit facility initially bore interest at either LIBOR plus 2.75% or at the base rate plus 1.75%, and then will be subject to a step-down based on SS&C’s consolidated net senior secured leverage ratio and would be equal to 2.50% in the case of the LIBOR margin, and 1.50% in the case of the base rate margin. The term B loans initially bore interest at either LIBOR plus 4.00% or at base rate plus 3.00%, with LIBOR subject to a 1.00% floor.
	In November 2014, the Company drew down on the revolving credit facility in the amount of $75.0 million to fund part of the purchase price of the acquisition of DST Global Solutions Ltd. and DST Global Solutions LLC (together “DSTGS”), subsidiaries of DST Systems, Inc. See Note 12 for further discussion of acquisitions.
	In February 2014, the Company completed a repricing of its term A-2 loans, which replaced these loans with new term A-2 loans at the same outstanding principal balance but at a different interest rate. The applicable interest rates were reduced to either LIBOR plus 2.0% or the base rate plus 1.0%. The maturity date of the new loans remains December 8, 2017, and no changes were made to the financial covenants or scheduled amortization.
	In June 2013, the Company completed a repricing of its term B-1 loans and term B-2 loans, which replaced these loans with new term B-1 loans and term B-2 loans at the same outstanding principal balance, but at a different interest rate. The applicable interest rates were reduced to either LIBOR plus 2.75% or the base rate plus 1.75%, and the LIBOR floor was reduced from 1.00% to 0.75%, subject to a step-down at any time that the consolidated net senior secured leverage ratio is less than 2.75 times, to 2.50% in the case of the LIBOR margin, and 1.50% in the case of the base rate margin. The maturity date of the new loans remains June 8, 2019, and no changes were made to the financial covenants or scheduled amortization.
	The repricing of the debt 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 repricing as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to the amounts that exited the syndicate.
	Holdings, SS&C and the material domestic subsidiaries of SS&C have pledged substantially all of their tangible and intangible assets as security to support the obligations of SS&C and SS&C Sarl under the Credit Agreement. In addition, SS&C Sarl has agreed, in certain circumstances, to cause subsidiaries in foreign jurisdictions to guarantee SS&C Sarl’s obligations and pledge substantially all of their assets to support the obligations of SS&C Sarl under the Credit Agreement. The Credit Agreement contains customary restrictive covenants and a financial covenant requiring the Company to maintain a specified consolidated net senior secured leverage ratio. As of December 31, 2014, the Company was in compliance with the financial and non-financial covenants.
	In connection with the entry into the Credit Agreement, SS&C terminated its prior senior credit facility (“Senior Credit Facility”) and used the initial proceeds of the borrowings to repay all amounts outstanding under the Senior Credit Facility, including an aggregate principal amount of outstanding borrowings of approximately $260.0 million, and to satisfy a portion of the consideration required to fund the Company’s acquisition of GlobeOp. At the time of the termination of the Senior Credit Facility, all liens and other security interests that SS&C had granted to the lenders under the Senior Credit Facility were released.
	At December 31, 2014, annual maturities of long-term debt during the next five years and thereafter are as follows (in thousands):

Derivatives and Hedging Activities	7. Derivatives and Hedging Activities
	Derivative financial instruments are recognized on the consolidated balance sheets as either assets or liabilities and are measured at fair value. Changes in the fair values of derivatives are recorded each period in earnings or accumulated other comprehensive income, depending on whether a derivative qualifies for hedge accounting and is effective as part of a hedged transaction. Gains and losses on derivative instruments reported in accumulated other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not use derivative instruments for speculative purposes. The Company had no derivative instruments as of December 31, 2014 and 2013.
	On March 14, 2012, SS&C and SS&C Sarl entered into a cooperation agreement with GlobeOp, pursuant to which SS&C Sarl issued an announcement disclosing that the Company and GlobeOp had agreed on the terms of a recommended cash offer (the “Offer”) to be made by SS&C Sarl to acquire the entire issued and to be issued share capital of GlobeOp for cash of 485 pence per share. As a result of the Offer’s foreign currency denomination, the Company was exposed to market risks relating to fluctuations in foreign currency exchange rates. In conjunction with the Offer, the Company entered into a forward currency transaction and a currency option transaction to protect against the foreign currency exchange rate risk that existed. The transactions were contingent upon the Offer meeting the acceptance conditions and were not designated as hedge transactions. During the three months ended June 30, 2012, the forward contract was utilized at an average exchange rate of $1.584 to £1.0 on a notional amount of £423.0 million, and the option contract was sold. These transactions resulted in a loss of $14.3 million recorded in other expense on the Consolidated Statements of Comprehensive Income for the year ended December 31, 2012.

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. 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, 2014 and 2013, 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 financial assets or liabilities that were measured at fair value as of December 31, 2014. The table below segregates all financial assets and liabilities that were measured at fair value on a recurring basis (at least annually) into the most appropriate level within the fair value hierarchy based on the inputs used to determine their fair value at the measurement date in 2013 (in thousands):
			Total Carrying		Level 1		Level 2		Level 3
			Value at
			December 31, 2013
	Assets		$	—	$	—	$	—	$	—
	Liabilities:
	Contingent consideration		$	500	$	—	$	—	$	500
	Total liabilities		$	500	$	—	$	—	$	500
	The Company determines the fair value of the contingent consideration liabilities associated with its acquisitions based on the potential payments of the liability associated with the unobservable input of the estimated post-acquisition financial results (the achievement of certain revenue and EBITDA targets) of the related acquisition through a certain date. As such, contingent consideration liabilities are a Level 3 liability. As of December 31, 2013, the Company’s contingent consideration liability was measured at fair value using estimated future cash flows based on the potential payments of the liability based on the unobservable input of the estimated post-acquisition financial results of Prime Management Limited (“Prime”) through September 30, 2014. The Company increased this contingent consideration liability to a fair value of $0.9 million and recorded the adjustment of $0.4 million to other expense in the second quarter of 2014. This consideration was paid out in the fourth quarter of 2014. See Note 12 for further discussion of acquisitions.
	The carrying amounts and fair values of financial instruments at December 31, 2014 and 2013 are as follows (in thousands):
			2014				2013
			Carrying		Fair		Carrying		Fair
			Amount		Value		Amount		Value
	Financial liabilities:
	Credit facility		$	645,000	$	641,141	$	774,507	$	783,606
	The above fair values were computed based on comparable quoted market prices or an estimate of the amount to be paid to terminate or settle the agreement, as applicable. 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.

Stock-based Compensation	11. Stock-based Compensation
	In February 2014, the Company’s Board of Directors adopted an equity-based incentive plan (“the 2014 Plan”), which authorizes stock options to be granted for up to 3,000,000 shares of the Company’s common stock, Under the 2014 Plan, which became effective in May 2014 upon stockholder approval, the exercise price of stock options is set on the grant date and may not be less than the fair market value per share on such date. Generally, stock options expire ten years from the date of grant. The Company has granted time-based stock options under the 2014 Plan.
	In April 2008, the Company’s Board of Directors adopted, and its stockholders approved, an equity-based incentive plan (“the 2008 Plan”), which authorizes equity awards to be granted for up to 9,498,306 shares of the Company’s common stock, which is calculated based on an initial authorization of 1,416,661 shares of the Company’s common stock and an annual increase to be added on the first day of each of the Company’s fiscal years during the term of the 2008 Plan beginning in fiscal 2009 equal to the lesser of (i) 1,416,661 shares of common stock, (ii) 2% of the outstanding shares on such date or (iii) an amount determined by the Company’s board of directors. Under the 2008 Plan, which became effective in July 2008, the exercise price of awards is set on the grant date and may not be less than the fair market value per share on such date. Generally, awards expire ten years from the date of grant. The Company has granted time-based options under the 2008 Plan.
	In August 2006, the Company’s Board of Directors adopted an equity-based incentive plan (“the 2006 Plan”), which authorizes equity awards to be granted for up to 11,173,819 shares of the Company’s common stock. Under the 2006 Plan, the exercise price of awards is set on the grant date and may not be less than the fair market value per share on such date. Generally, awards expire ten years from the date of grant. The Company has granted restricted shares of its common stock and both time-based and performance-based options under the 2006 Plan.
	The Company generally settles stock option exercises with newly issued common shares.
	Restricted shares. During the year ended December 31, 2013, the Company granted 25,000 restricted shares of its common stock under the 2006 Plan, which vested 25% on the first anniversary of the grant date and continue to vest 1/12th of the remaining balance each quarter thereafter for three years. The restricted shares vest in full upon a change in control, subject to certain conditions.
	Time-based options. Time-based options granted under the 2006 Plan, the 2008 Plan or the 2014 Plan generally vest 25% on the first anniversary of the grant date and 1/36th of the remaining balance each month thereafter for 36 months. All outstanding time-based options vest upon a change in control, subject to certain conditions. Time-based options granted during 2014, 2013 and 2012 have a weighted-average grant date fair value of $12.77, $9.86 and $5.79 per share, respectively, based on the Black-Scholes option pricing model. Compensation expense is recorded on a straight-line basis over the requisite service period. The fair value of time-based options vested during the years ended December 31, 2014, 2013 and 2012 was approximately $11.3 million, $8.2 million and $4.9 million, respectively. At December 31, 2014, there was approximately $48.2 million of unearned non-cash stock-based compensation related to time-based options that the Company expects to recognize as expense over a weighted average remaining period of approximately three years.
	For the time-based options valued using the Black-Scholes option-pricing model, the Company used the following weighted-average assumptions:
			Time-Based awards
			2014			2013			2012
	Expected term to exercise (years)			4			4			4
	Expected volatility			29.04	%		28.04	%		32.14	%
	Risk-free interest rate			1.36	%		1.16	%		0.45	%
	Expected dividend yield			0.84	%		0	%		0	%
	Expected volatility prior to March 2014 was based on a combination of the Company’s historical volatility as a public company and historical volatility of the Company’s peer group. Beginning in March 2014 on the four-year anniversary of the Company’s initial public offering, expected volatility is based on the Company’s historical volatility as a public company. Expected term to exercise is based on the Company’s historical stock option exercise experience.
	Total restricted stock and stock options. The amount of stock-based compensation expense recognized in the Company’s Consolidated Statements of Comprehensive Income for the years ended December 31, 2014, 2013 and 2012 was as follows (in thousands):

Acquisitions	12. Acquisitions
	DST Global Solutions
	On November 30, 2014, SS&C purchased the assets of DSTGS for approximately $95.0 million, plus the costs of effecting the transaction and the assumption of certain liabilities. DSTGS provides investment management software and services.
	The net assets and results of operations of DSTGS have been included in the Company’s consolidated financial statements from December 1, 2014. The purchase price was allocated to tangible and intangible assets based on their fair value at the date of acquisition. The fair value of the intangible assets, consisting of completed technology, customer relationships and trade name, was determined using the income approach. Specifically, the discounted cash flows method was utilized for customer relationships, and the relief-from-royalty method was utilized for the completed technology and trade name. The completed technology is amortized over approximately seven and eight years, customer relationships are amortized over approximately 10 to 15 years and trade names are amortized over approximately 10 years, in each case the estimated lives of the assets. The remainder of the purchase price was allocated to goodwill and is primarily not tax deductible.
	There are $7.2 million in revenues from DSTGS operations included in the Consolidated Statement of Comprehensive Income for the year ended December 31, 2014.
	Gravity
	On September 27, 2012, SS&C purchased the assets of Gravity Financial (“Gravity”) for approximately $5.7 million, plus the costs of effecting the transaction and the assumption of certain liabilities. Gravity provides full-service fund administration.
	The net assets and results of operations of Gravity have been included in the Company’s consolidated financial statements from September 28, 2012. The purchase price was allocated to tangible and intangible assets based on their fair value at the date of acquisition. The fair value of the intangible assets, consisting of trade name and customer relationships, was determined using the income approach. Specifically, the discounted cash flows method was utilized for customer relationships, and the relief-from-royalty method was utilized for the trade name. The intangible assets 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. The customer relationships and trade name are each amortized over approximately seven years, in each case the estimated lives of the assets. The remainder of the purchase price was allocated to goodwill and is tax deductible.
	GlobeOp
	On May 31, 2012, SS&C purchased the issued and to be issued share capital of GlobeOp for approximately $834.4 million using existing cash and debt financing as discussed in Note 6, plus the costs of effecting the transaction and the assumption of liabilities. GlobeOp provides independent fund services, specializing in middle- and back-office services and integrated risk-reporting to hedge funds, asset management firms and other sectors of the financial industry.
	The net assets and results of operations of GlobeOp have been included in the Company’s consolidated financial statements from June 1, 2012. The purchase price was allocated to tangible and intangible assets based on their fair value at the date of acquisition. The fair value of the intangible assets, consisting of completed technology, trade name and customer relationships, was determined using the income approach. Specifically, the relief-from-royalty method was utilized for the completed technology and trade name, and the discounted cash flows method was utilized for the customer relationships. The intangible assets 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. The completed technology is amortized over approximately eight years, customer relationships are amortized over approximately nine years and trade name is amortized over approximately 17 years, in each case the estimated lives of the assets. The remainder of the purchase price was allocated to goodwill and is not tax deductible.
	The PORTIA Business
	On May 9, 2012, SS&C purchased the assets of Thomson Reuters’ PORTIA Business (“the PORTIA Business”) for approximately $170.0 million, plus the costs of effecting the transaction and the assumption of certain liabilities. The PORTIA Business provides a broad set of middle-to-back office capabilities that allow investment managers to track and manage the day-to-day activity in their investment portfolios.
	The net assets and results of operations of the PORTIA Business have been included in the Company’s consolidated financial statements from May 10, 2012. The purchase price was allocated to tangible and intangible assets based on their fair value at the date of acquisition. The fair value of the intangible assets, consisting of non-compete agreement, completed technology, trade name and customer relationships, was determined using the income approach. Specifically, the discounted cash flows method was utilized for the non-compete agreement and customer relationships, and the relief-from-royalty method was utilized for the completed technology and trade name. The intangible assets 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. The non-compete agreement is amortized over approximately three years, completed technology is amortized over approximately seven years, customer relationships are amortized over approximately 10 years and trade name is amortized over approximately nine 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 consideration paid, net of cash acquired above for DSTGS includes an estimated working capital adjustment of approximately $8.0 million anticipated to be paid in the first quarter of 2015.
	The fair value of acquired accounts receivable balances approximates the contractual amounts due from acquired customers, except for approximately $0.5 million, $0.3 million and $1.2 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 — DSTGS, GlobeOp and the PORTIA Business, 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 acquisition of DSTGS occurred on January 1, 2013 and the acquisition of Prime occurred on January 1, 2012. 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.

	Millennium Actions
	Several actions (the “Millennium Actions”) have been filed in various jurisdictions against the Company’s subsidiary, GlobeOp, alleging claims and damages with respect to a valuation agent services agreement performed by GlobeOp for the Millennium Global Emerging Credit Fund, L.P. and Millennium Global Emerging Credit Fund Ltd. (the “Millennium Funds”). These actions include (i) a putative class action in the U.S. District Court for the Southern District of New York (the “U.S. Class Action”) on behalf of a putative class of investors in the Millennium Funds filed in May 2012 asserting claims of $844 million (the alleged aggregate value of assets under management by the Millennium Funds at the funds’ peak valuation); (ii) an arbitration proceeding in the United Kingdom (the “UK Arbitration”) on behalf of Millennium Global Investments Ltd. and Millennium Asset Management Ltd., the Millennium Funds’ investment manager and administrative manager, respectively (together, the “Millennium Managers”), which commenced with a request for arbitration in July 2011, seeking an indemnity of $26.5 million for sums paid by way of settlement to the Millennium Funds in a separate arbitration to which GlobeOp was not a party, as well as an indemnity for any losses that may be incurred by the Millennium Managers in the U.S. Class Action; and (iii) a claim in the same arbitration proceeding by the liquidators on behalf of the Millennium Global Emerging Credit Master Fund Ltd. (the “Master Fund”) against GlobeOp for damages alleged to be in excess of $160 million. These actions allege that GlobeOp breached its contractual obligations and/or negligently breached a duty of care in the performance of services for the Millennium Fund and that, inter alia, GlobeOp should have discovered and reported a fraudulent scheme perpetrated by the portfolio manager employed by the investment manager. The U.S. Class Action also asserts claims against SS&C identical to the claims against GlobeOp in that action. In the arbitration, GlobeOp has asserted counterclaims against both the Millennium Managers and the Master Fund for indemnity, including in respect of the U.S. Class Action.
	Hearings in the UK Arbitration were conducted in London in July and August 2013, September 2014 and December 2014.
	GlobeOp has secured insurance coverage that provides reimbursement of various litigation costs up to pre-determined limits. Since 2012, GlobeOp has been reimbursed for litigation costs under the applicable insurance policy.
	In January 2014, GlobeOp, SS&C, the Millennium Managers and the plaintiff in the U.S. Class Action entered into a settlement agreement resolving all disputes and claims between and among the parties (including a separate mutual release between and among GlobeOp and SS&C, on the one hand, and the Millennium Managers on the other that covers claims asserted in the UK Arbitration). The settlement agreement was approved by the United States District Court for the Southern District of New York on July 7, 2014 and consummated in August 2014. Accordingly, the U.S. Class Action matter has been dismissed with prejudice and is now concluded. GlobeOp’s insurers funded the entirety of the settlement amount contemplated to be contributed by GlobeOp. The resolution of the U.S. Class Action does not affect the claims, counterclaims and/or defenses as between GlobeOp and the Master Fund that have been asserted in the UK Arbitration.
	The Company cannot predict the outcome of the UK Arbitration. The Company believes that it has strong defenses and is vigorously contesting the UK Arbitration (as described above, the U.S. Class Action has been concluded). The amount of any potential loss, if any at all, cannot be reasonably estimated at this time.
	In addition to the foregoing legal proceedings, from time to time, the Company is subject to other legal proceedings and claims. In the opinion of the Company’s management, the Company is not involved in any other such litigation or proceedings with third parties that management believes would have a material adverse effect on the Company or its business.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
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. 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.
Revenue Recognition	Revenue Recognition
	The Company’s payment terms for software licenses typically require that the total fee be paid upon signing of the contract. Maintenance services are typically due in full at the beginning of the maintenance 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 relates 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 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 contracts in advance of services being performed over the contractual term.
Software-enabled Services Revenue	Software-enabled Services Revenue
	The Company’s software-enabled services arrangements make its software applications available to its clients for processing of transactions. The software-enabled services arrangements provide an alternative for clients who do not wish to install, run and maintain complicated financial software. Under the 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 non-cancelable 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 pervasive 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.
Software Licenses Revenue	Software 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 vendor-specific objective evidence (“VSOE”). The Company recognizes software 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 software 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 also sells term licenses ranging from one to seven years, some of which include bundled maintenance services. For those arrangements with bundled maintenance services, VSOE does not exist for the maintenance element and therefore the total fee is recognized ratably over the contractual term of the arrangement. The Company classifies revenues from bundled term license arrangements as both software licenses and maintenance revenues by allocating a portion of the revenues from the arrangement to maintenance revenues and classifying the remainder in software licenses revenues. The Company uses its renewal rates for maintenance under perpetual license agreements for the purpose of determining the portion of the arrangement fee that is classified as maintenance revenues.
	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.
Maintenance Revenue Agreements	Maintenance Revenue Agreements
	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.
Professional Services Revenue	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 begins upon the establishment of technological feasibility based on a working model. Net capitalized software costs of $4.2 million and $3.5 million are included in the December 31, 2014 and 2013 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 $1.8 million, $1.0 million, and $0.5 million for each of the years ended December 31, 2014, 2013, and 2012, 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, expected volatility of the Company’s stock price, and the number of awards expected to be forfeited. 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 could be an income tax expense for the portion of the deferred tax asset that is not realizable.
Other Income (Expense), Net	Other Income (Expense), Net
	Other income, net for 2014 consists primarily of foreign currency transaction gains of $2.9 million. The gains were partially offset by an increase of $0.4 million to the contingent consideration liability for the acquisition of Prime Management Limited (“Prime”). Other income, net for 2013 consists primarily of foreign currency transaction gains of $3.4 million. Other expense, net for 2012 consists primarily of foreign currency transaction losses of $12.4 million and a loss of $3.8 million recorded on foreign currency contracts associated with the acquisition of GlobeOp Financial Services, S.A. (“GlobeOp”), which is discussed further in Note 12. These losses were partially offset by a reduction of the Company’s remaining contingent consideration liability associated with the BenefitsXML, Inc. acquisition from $0.3 million to $0.
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.
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, 2014 and 2013.
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 letter of credits 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 Sheet. Additionally, movements of restricted cash are included in other investing activities on the Consolidated Statement of Cash Flows.
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, 2014, 2013 and 2012 was $14.3 million, $14.7 million and $10.7 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 other income (expense), net.
Goodwill and Intangible Assets	Goodwill and Intangible Assets
	The Company tests goodwill annually for impairment as of December 31st (and in interim periods if certain events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount). The Company has completed the required impairment tests for goodwill and has determined that no impairment existed as of December 31, 2014 or 2013. The first step of the impairment analysis, which is based on our reporting unit structure, indicated that the fair value significantly exceeded the carrying value at December 31, 2014. There were no other indefinite-lived intangible assets as of December 31, 2014 or 2013.
	The following table summarizes changes in goodwill (in thousands):
	Balance at December 31, 2012		1,559,607
	2013 acquisitions		910
	Adjustments to previous acquisitions		(202	)
	Income tax benefit on rollover options exercised		(3,567	)
	Effect of foreign currency translation		(15,362	)
	Balance at December 31, 2013		1,541,386
	2014 acquisition		66,511
	Effect of foreign currency translation		(34,670	)
	Balance at December 31, 2014	$	1,573,227
	Completed technology and other identifiable intangible assets are amortized over lives ranging from three to 17 years based on the ratio that current cash flows for the intangible asset bear to the total of current and expected future cash flows for the intangible asset. Amortization expense associated with completed technology and other amortizable intangible assets was $83.7 million, $84.1 million and $64.6 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	A summary of the components of intangible assets is as follows (in thousands):
		December 31,
		2014			2013
	Customer relationships	$	604,638		$	599,186
	Completed technology		154,043			122,758
	Trade names		39,876			36,072
	Other		2,774			2,887
			801,331			760,903
	Less: accumulated amortization		(412,897	)		(336,712	)
		$	388,434		$	424,191
	Total estimated amortization expense, related to intangible assets, for each of the next five years, as of December 31, 2014, is expected to approximate (in thousands):
	Year Ending December 31,
	2015	$	87,466
	2016		78,591
	2017		60,187
	2018		53,906
	2019		44,041
		$	324,191
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, 2014 and 2013.
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, 2014 and 2013, 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 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 income (expense) in the results of operations in the periods in which they occur.
Comprehensive Income	Comprehensive Income
	Items defined as comprehensive income, such as foreign currency translation adjustments, are separately classified in the financial statements. The accumulated balance of other comprehensive income is reported separately from retained earnings and additional paid-in capital in the equity section of the Consolidated Balance Sheet. Total comprehensive income consists of net income and other accumulated comprehensive income disclosed in the equity section of the Consolidated Balance Sheet.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). This ASU establishes specific guidance to an organization’s management on their responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. The provisions of ASU 2014-15 are effective for interim and annual periods beginning after December 15, 2016. This ASU is not expected to have an impact on the Company’s financial position, results of operations or cash flows.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The objective of ASU 2014-09 is to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of ASU 2014-09 are effective for interim and annual periods beginning after December 15, 2016. The Company is currently evaluating the impact of this standard on its financial position, results of operations and cash flows.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740) – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). The objective of ASU 2013-11 is to end some inconsistent practices with regard to the presentation on the balance sheet of unrecognized tax benefits. ASU 2013-11 is effective for financial statement periods beginning after December 15, 2013, with early adoption permitted. The adoption of this standard in the first quarter of 2014 did not have a material impact on the Company’s financial position, results of operations or cash flows.
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 and restricted stock 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 weighted average common shares used in the computation of basic and diluted EPS (in thousands):
		Year Ended December 31,
		2014			2013			2012
	Weighted average common shares outstanding — used in calculation of basic EPS		83,314			81,195			78,321
	Weighted average common stock equivalents — options and restricted shares		4,017			4,421			4,567
	Weighted average common and common equivalent shares outstanding — used in calculation of diluted EPS		87,331			85,616			82,888
	Options to purchase 1,841,840, 133,598 and 703,446 shares were outstanding for the years ended December 31, 2014, 2013 and 2012, respectively, but were not included in the computation of diluted EPS because the effect of including the options would be anti-dilutive.
