Financial Statement Presentation	Financial Statement Presentation
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts and results of operations of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements.
	Interim Financial Presentation
	The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”) as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification for interim financial information and Article 10 of Regulation S-X issued by the United States Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the financial position, results of operations, comprehensive income, changes in stockholders’ equity and cash flows. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015 or any other period. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 25, 2015.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from these estimates.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued a new accounting standard related to revenue recognition. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The standard is effective for annual periods beginning after December 15, 2016 including interim periods within that reporting period, and early adoption is not permitted. The standard can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the impact of adopting this new standard on its financial statements.

Fair Value Disclosures [Abstract]
Investments and Fair Value Disclosures	Investments and Fair Value Disclosures
	Investments in Marketable Securities
	Marketable securities that the Company does not intend to hold to maturity are classified as available-for-sale, are carried at fair value and are included on the Company’s balance sheet as either short-term or long-term investments depending on their maturity. Investments with original maturities greater than three months that mature less than one year from the consolidated balance sheet date are classified as short-term investments. Investments with maturities greater than one year from the consolidated balance sheet date are classified as long-term investments. Available-for-sale investments are marked-to-market at the end of each reporting period, with unrealized holding gains or losses, which represent temporary changes in the fair value of the investment, reflected in accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company’s primary objective when investing excess cash is preservation of principal. The following table summarizes the Company’s investments:

	The carrying amounts of the Company’s other financial instruments, accounts receivable, accounts payable and accrued expenses, approximate their respective fair values due to their short-term nature. (See Note 7 Borrowings for additional information on the fair value of debt.)
	The Company uses a three-tier fair value measurement hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The three tiers are defined as follows:
	•	Level 1. Observable inputs based on unadjusted quoted prices in active markets for identical instruments and include the Company’s investments in money market funds and certificates of deposit;
	•	Level 2. Inputs valued using quoted market prices for similar instruments, nonbinding market prices that are corroborated by observable market data and include the Company’s investments and marketable securities in U.S. agency notes, commercial paper and corporate bonds; and
	•	Level 3. Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions.
	Assets Measured at Fair Value on a Recurring Basis
	The Company evaluates its financial assets subject to fair value measurements on a recurring basis to determine the appropriate level of classification for each reporting period. This determination requires significant judgments to be made. There were no transfers between classification levels during the periods. The following tables summarize the values (in thousands):
		March 31, 2015				Level 1		Level 2			Level 3

	Assets Measured at Fair Value on a Nonrecurring Basis
	The Company measures certain assets, including property and equipment, goodwill and intangible assets, at fair value on a nonrecurring basis. These assets are recognized at fair value when they are deemed to be impaired. During the three months ended March 31, 2015 and 2014, there were no fair value measurements of assets or liabilities measured at fair value on a nonrecurring basis subsequent to their initial recognition.

Software Licenses	Software Licenses
	In 2011, the Company entered into an agreement that provides the Company the right to distribute certain third-party software on an unlimited basis through May 2016 at a total cost of $10.2 million. To the extent billed license revenue over the four-year period exceeds $460 million, the Company would be required to pay additional fees. The $10.2 million is being amortized to cost of revenue over the four-year period beginning in June 2012 (the date when the previous agreement with the same vendor to distribute the software expired), based on the straight line method.
	Amortization expense related to this agreement was approximately $0.6 million for each of the three months ended March 31, 2015 and 2014.

	Convertible Senior Notes
	In June 2011, the Company issued $120.0 million aggregate principal amount of 1.50% convertible senior notes due in 2018 (the “Notes”). The Notes are senior unsecured obligations of the Company, with interest payable semi-annually in cash at a rate of 1.50% per annum, and will mature on July 1, 2018, unless earlier repurchased, redeemed or converted.
	The Notes may be converted by the holders of Notes at their option on any day prior to the close of business on the scheduled trading day immediately preceding April 1, 2018 only under the following circumstances: (a) during the five business-day period after any ten consecutive trading-day period (the “measurement period”) in which the trading price per Note for each day of that measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the applicable conversion rate on each such day; (b) during any calendar quarter (and only during such quarter) after the calendar quarter ended June 30, 2012, if the last reported sale price of the common stock for 20 or more trading days in a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter exceeds 130% of the applicable conversion price in effect on the last trading day of the immediately preceding calendar quarter; (c) upon the occurrence of specified corporate events; or (d) if the Company calls the Notes for redemption. The Notes will be convertible, regardless of the foregoing circumstances, at any time from, and including, April 1, 2018 through the second scheduled trading day immediately preceding the maturity date.
	The initial conversion rate for the Notes is 23.8126 shares of the Company’s common stock per $1,000 principal amount of Notes, equivalent to a conversion price of approximately $41.99 per share of common stock. The conversion price will be subject to adjustment in some events, but will not be adjusted for accrued interest. In addition, if a make-whole fundamental change, as defined in the indenture governing the Notes (the “Indenture”), occurs prior to the maturity date, the Company will in some cases increase the conversion rate for a holder that elects to convert its Notes in connection with such make-whole fundamental change. Upon conversion, the Company will pay cash up to the aggregate principal amount of the Notes to be converted and deliver shares of the common stock in respect of the remainder, if any, of the conversion obligation in excess of the aggregate principal amount of the Notes being converted. While the Notes were not convertible as of March 31, 2015, if the Notes were convertible, no shares would have been distributed upon conversion because the conversion price was above the stock price as of such date.
	Holders of the Notes may require the Company to repurchase some or all of the Notes for cash, subject to certain exceptions, upon a fundamental change, as defined in the Indenture, at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus any accrued and unpaid interest up to but excluding the relevant repurchase date.
	The Company may not redeem the Notes prior to July 1, 2015. Beginning July 1, 2015, the Company may redeem for cash all or part of the Notes (except for the Notes that the Company is required to repurchase as described above) if the last reported sale price of the common stock exceeds 140% of the applicable conversion price for 20 or more trading days in a period of 30 consecutive trading days ending on the trading day immediately prior to the date of the redemption notice. The redemption price will equal the sum of 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, plus a “make-whole premium” payment. The Company must make the make-whole premium payments on all Notes called for redemption prior to the maturity date, including Notes converted after the date the Company delivered the notice of redemption.
	The Company has separately accounted for the liability and equity components of the convertible debt instrument by allocating the gross proceeds from the issuance of the Notes between the liability component and the embedded conversion option, or equity component. This allocation was done by first estimating an interest rate at the time of issuance for similar notes that do not include the embedded conversion option. This interest rate, estimated at 8%, was used to compute the initial fair value of the liability component of $79.4 million. The excess of the gross proceeds received from the issuance of the Notes over the initial amount allocated to the liability component, of $40.6 million, was allocated to the embedded conversion option, or equity component. This excess is reported as a debt discount and subsequently amortized as interest expense, using the interest method, through July 2018, the maturity date of the Notes. Offering costs, consisting of the initial purchasers’ discount and offering expenses payable by the Company, were $4.3 million. These offering costs were allocated to the liability component and the equity component based on the relative valuations of such components. As a result, $2.9 million of the offering costs were classified as debt issuance costs and recorded on the balance sheet in other assets. The remaining $1.4 million of offering costs were allocated to the equity component.
	The fair value of the Notes as of March 31, 2015 and December 31, 2014 was $126.2 million and $125.1 million, respectively. The carrying amount of the equity component of the Notes was $21.5 million at March 31, 2015. The unamortized offering costs at March 31, 2015 were $1.3 million which is being amortized as interest expense through the July 2018 maturity date of the Notes.
	The following table shows the amounts recorded within the Company’s financial statements with respect to the Notes (in thousands):
		March 31, 2015			December 31, 2014
	Convertible debt principal	$	120,000		$	120,000

	Fair Value of Borrowings
	Fair value for the Company’s borrowings is estimated using quoted market prices of the Notes at March 31, 2015, quoted market prices for similar instruments and by observable market data. The Company believes its creditworthiness and the financial market in which it operates has not materially changed since entering into the arrangements. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy.

Stock-based Compensation	Stock-based Compensation
	Equity Incentive Plans
	In 1999, the Company adopted the 1999 Stock Incentive Plan (the “1999 Plan”). The 1999 Plan terminated in June 2009 whereby no new options or awards are permitted to be granted. In April 2009, the Company adopted the 2009 Equity Incentive Plan. This plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units (“RSUs”) and stock appreciation rights. In June 2010, in connection with the Company’s initial public offering (“IPO”), the 2009 Equity Incentive Plan was amended and restated to provide for, among other things, annual increases in the share reserve (as amended and restated, the “2009 Plan”).
	The term of stock-based grants is up to ten years, except that certain stock-based grants during fiscal years 2006 through 2009 have a term of five years. The requisite vesting period for grants made under the 2009 Plan is typically three or four years. On each of January 1, 2014 and 2015, 1,250,000 shares were added to the 2009 Plan. At March 31, 2015, the Company had 2,412,826 shares of common stock available for issuance under the 2009 Plan.
	Stock-based compensation expense recognized by the Company was as follows (in thousands):

	Vested and Exercisable at March 31, 2015	950,023		$	24.99		6.23	$10,498
	During the three months ended March 31, 2015 and 2014, the Company granted stock options with a weighted-average grant date fair value of $13.56 and $15.35, respectively. For three months ended March 31, 2015 and 2014, the intrinsic value of stock options exercised was $0.7 million and $0.4 million, respectively, and cash received from stock options exercised was $0.8 million and $0.1 million, respectively.
	At March 31, 2015, unrecognized stock-based compensation expense, net of estimated forfeitures, related to unvested stock options was $5.4 million, which is scheduled to be recognized over a weighted average period of 1.24 years. To the extent the actual forfeiture rate is different than what the Company has anticipated at March 31, 2015, stock-based compensation expense will be different from expectations.
	Restricted Stock Units
	The following table presents a summary of activity for RSUs (excluding RSUs that are subject to performance-based vesting conditions (“PSUs”)):
		Number of RSUs		Weighted Average Grant Date Fair Value
	Balance, December 31, 2014	1,029,787		$	32.06
	Granted	175,512		28.42

	Forfeited	(6,870	)	31.36
	Balance, March 31, 2015	1,073,230		$	31.29
	The RSUs generally vest over three or four years from the vesting commencement date and on vesting the holder receives one share of common stock for each RSU.
	At March 31, 2015, unrecognized stock-based compensation expense related to unvested RSUs was $11.2 million, which is scheduled to be recognized over a weighted average period of 1.09 years. To the extent the actual forfeiture rate is different than what the Company has anticipated at March 31, 2015, stock-based compensation expense will be different from expectations.
	Performance Stock Units
	The following table presents a summary of activity for PSUs:

	Granted	—		—
	Vested	—		—
	Forfeited	—		—
	Balance, March 31, 2015	557,588		$	26.88
	The PSUs generally vest over three or four years from the vesting commencement date, subject to the satisfaction of certain performance conditions, and on vesting the holder receives one share of common stock for each PSU.
	At March 31, 2015, unrecognized stock-based compensation expense related to unvested PSUs was $3.3 million, which is scheduled to be recognized over a weighted average period of 1.23 years. To the extent the actual forfeiture rate is different than what the Company has anticipated at March 31, 2015, stock-based compensation expense will be different from expectations.
	Tax Benefits
	Upon adoption of the FASB’s guidance on stock-based compensation, the Company elected the alternative transition method (short cut method) provided for calculating the tax effects of stock-based compensation. The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (“APIC pool”) related to the tax effects of employee stock-based compensation, and to determine the subsequent impact on the APIC pool and consolidated statements of cash flows related to the tax effect of employee stock-based compensation awards that are outstanding upon adoption. As of March 31, 2015, the Company’s APIC pool balance was $18.9 million.
	The Company applies a with-and-without approach in determining its intra-period allocation of tax expense or benefit attributable to stock-based compensation deductions. Tax deductions in excess of previously recorded benefits (windfalls) included in net operating loss carryforwards but not reflected in deferred tax assets were $25.9 million and $49.9 million at March 31, 2015 and December 31, 2014, respectively.

	In the normal course of business, the Company enters into contracts and agreements that may contain representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made in the future, but have not yet been made. The Company has not paid any material claims related to indemnification obligations to date.
	In accordance with its bylaws and certain agreements, the Company has indemnification obligations to its officers and directors for certain events or occurrences, subject to certain limits, while they are serving at the Company’s request in such capacity. There have been no claims to date under these indemnification obligations.
	In addition, the Company is involved in litigation incidental to the conduct of its business. The Company is not a party to any lawsuit or proceeding that, in the opinion of management, is reasonably possible to have a material adverse effect on its financial position, results of operations or cash flows.

Income Tax Disclosure [Abstract]
Taxes	Taxes
	The Company’s provision for income taxes is determined using an estimate of its annual effective tax rate for each of its legal entities in accordance with the accounting guidance for income taxes. Where the Company has entities with losses and does not expect to realize the tax benefits in the foreseeable future, those entities are excluded from the effective tax calculation. Non-recurring and discrete items that impact tax expense are recorded in the period incurred.
	The effective tax rate was 40.4% and 32.5% for the three months ended March 31, 2015 and 2014, respectively. Our provision for income taxes is greater than the computed U.S. statutory rate due primarily to state taxes, valuation allowances in certain foreign jurisdictions and certain non-deductible share-based and other compensation items. For the three months ended March 31, 2015 and 2014, the Company had a benefit from income taxes of $1.4 million and $3.6 million, respectively.
	The Company has not recorded a deferred tax liability for undistributed earnings of $6.8 million of certain foreign subsidiaries, since such earnings are considered to be reinvested indefinitely. If the earnings were distributed, the Company would be subject to federal income and foreign withholding taxes. Determination of an unrecognized deferred income tax liability with respect to such earnings is not practicable.

Earnings Per Share [Abstract]
Income per share data	Income per share data
	Basic income per common share is computed based on the weighted average number of outstanding shares of common stock. Diluted income per common share adjusts the basic weighted average common shares outstanding for the potential dilution that could occur if stock options, RSUs and convertible securities were exercised or converted into common stock.
	The following table presents a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation. In the table below, net loss represents the numerator and weighted average common shares outstanding represent the denominator:
		Three Months Ended March 31,
		2015			2014
		(In thousands, except per share data)
	Net loss	$	(2,006	)	$	(7,452	)
	Weighted average common shares outstanding, basic and diluted	28,991			28,419
	Net loss per share, basic and diluted	$	(0.07	)	$	(0.26	)
	Due to the cash settlement feature of the principal amount of the Notes, we only include the impact of the premium feature in our diluted earnings per common share calculation when the average stock price exceeds the conversion price of the Notes, which did not occur for the three months ended March 31, 2015 and 2014.
	The weighted average number of shares outstanding used in the computation of diluted loss per share does not include the effect of stock-based awards convertible into 1,090,556 and 1,328,579 shares for the three months ended March 31, 2015 and 2014, respectively, as the effect would have been anti-dilutive given the Company’s losses for these periods.
	The weighted average number of shares outstanding used in the computation of diluted loss per share also does not include the effect of certain additional stock-based awards convertible into 1,031,210 and 1,227,744 shares for the three months ended March 31, 2015 and 2014, respectively, as their effect would have been anti-dilutive because their exercise prices exceeded the average market price of the Company's common stock during these periods.

Segment and Geographic Information	Segment and Geographic Information
	Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its chief executive officer (the “CEO”). The CEO reviews financial information presented on a consolidated basis, along with information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. Discrete information on a geographic basis, except for revenue, is not provided below the consolidated level to the CEO. The Company has concluded that it operates in one segment and has provided the required enterprise-wide disclosures.

Principles of Consolidation	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts and results of operations of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in the accompanying unaudited condensed consolidated financial statements.
Interim Financial Presentation	Interim Financial Presentation
	The accompanying unaudited condensed consolidated financial statements and footnotes have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”) as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification for interim financial information and Article 10 of Regulation S-X issued by the United States Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the financial position, results of operations, comprehensive income, changes in stockholders’ equity and cash flows. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of results that may be expected for the year ending December 31, 2015 or any other period. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on February 25, 2015.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from these estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the FASB issued a new accounting standard related to revenue recognition. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The standard is effective for annual periods beginning after December 15, 2016 including interim periods within that reporting period, and early adoption is not permitted. The standard can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the impact of adopting this new standard on its financial statements.
Investments in Marketable Securities	Investments in Marketable Securities
	Marketable securities that the Company does not intend to hold to maturity are classified as available-for-sale, are carried at fair value and are included on the Company’s balance sheet as either short-term or long-term investments depending on their maturity. Investments with original maturities greater than three months that mature less than one year from the consolidated balance sheet date are classified as short-term investments. Investments with maturities greater than one year from the consolidated balance sheet date are classified as long-term investments. Available-for-sale investments are marked-to-market at the end of each reporting period, with unrealized holding gains or losses, which represent temporary changes in the fair value of the investment, reflected in accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company’s primary objective when investing excess cash is preservation of principal.
Fair Value Measurements	The carrying amounts of the Company’s other financial instruments, accounts receivable, accounts payable and accrued expenses, approximate their respective fair values due to their short-term nature. (See Note 7 Borrowings for additional information on the fair value of debt.)
	The Company uses a three-tier fair value measurement hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The three tiers are defined as follows:
	•	Level 1. Observable inputs based on unadjusted quoted prices in active markets for identical instruments and include the Company’s investments in money market funds and certificates of deposit;
	•	Level 2. Inputs valued using quoted market prices for similar instruments, nonbinding market prices that are corroborated by observable market data and include the Company’s investments and marketable securities in U.S. agency notes, commercial paper and corporate bonds; and
	•	Level 3. Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions.
	Assets Measured at Fair Value on a Recurring Basis
	The Company evaluates its financial assets subject to fair value measurements on a recurring basis to determine the appropriate level of classification for each reporting period. This determination requires significant judgments to be made. There were no transfers between classification levels during the periods.
Revenue Recognition	Deferred revenue represents amounts billed to or collected from customers for which the related revenue has not been recognized because one or more of the revenue recognition criteria have not been met.
