	2	Summary of Significant Accounting Policies
	Basis of Presentation
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and include the accounts of Vocus, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. The consolidated balance sheet at December 31, 2012 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on March 11, 2013.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, software development costs, useful lives of property, equipment and software, intangible assets and goodwill, contingent liabilities, self-insurance, revenue recognition, fair value of stock-based awards and income taxes, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities as well as the reported amounts of revenues and expenses during the period. Actual results could differ from these estimates.
	Cash and Cash Equivalents
	The Company considers all highly liquid investments with original maturity dates of three months or less at the time of purchase to be cash equivalents.
	Investments
	Management determines the appropriate classification of investments at the time of purchase and evaluates such a determination as of each balance sheet date. The Company’s investments were classified as available-for-sale securities and were stated at fair value at December 31, 2012. Realized gains and losses are included in other income (expense) based on the specific identification method. Realized gains or losses for the three and nine months ended September 30, 2012, and 2013 were not material. Net unrealized gains and losses on available-for-sale securities are reported as a component of other comprehensive income (loss), net of tax. As of December 31, 2012, the net unrealized gains or losses on available-for-sale securities were not material. The Company regularly monitors and evaluates the fair value of its investments to identify other-than-temporary declines in value.

	Fair Value Measurements
	The Company measures certain financial assets at fair value pursuant to a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels:


	Level 1		—	Inputs are quoted prices in active markets for identical assets or liabilities.

	Level 2		—	Inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

	Level 3		—	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
	Allowance for Doubtful Accounts
	Estimates are used to determine the amount of the allowance for doubtful accounts necessary to reduce accounts receivable to the estimated net realizable value. These estimates are made by analyzing the status of significant past-due receivables and by establishing provisions for estimated losses by analyzing current and historical bad debt trends. The Company charges off uncollectible amounts against the allowance for doubtful accounts in the period in which it determines they are uncollectible. Actual collection experience has not varied significantly from prior estimates.
	Long-Lived Assets
	Long-lived assets include property, equipment and software and intangible assets with finite lives. Intangible assets consist of customer relationships, trade names and purchased technology acquired in business combinations. Intangible assets are amortized using the straight-line method over their estimated useful lives ranging from two to seven years. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an impairment indicator is present, the Company evaluates recoverability by a comparison of the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the estimated fair value of the assets. Impairment charges for long-lived assets for the nine months ended September 30, 2012 were $709,000. There were no impairment charges for long-lived assets for the nine months ended September 30, 2013.
	Business Combinations
	The Company has completed acquisitions of businesses that have resulted in the recording of goodwill and identifiable definite-lived intangible assets. The Company recognizes all of the assets acquired, liabilities assumed and contingent consideration at their fair values on the acquisition date. The Company uses significant estimates and assumptions, including fair value estimates, as of the acquisition date and refines those estimates that are provisional, as necessary, during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which new information may be gathered about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Measurement period adjustments are applied retrospectively. All other adjustments are recorded to the consolidated statements of operations. Acquisition-related costs are expensed as incurred separately from the acquisition and generally are included in general and administrative expenses in the consolidated statements of operations.
	Goodwill
	Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. The Company performs its annual impairment assessment on November 1, or whenever events or circumstances indicate impairment may have occurred. The Company operates under one reporting unit, and as a result, evaluates goodwill impairment based on the fair value of the Company as a whole. The Company did not record any impairment charges for goodwill during the nine months ended September 30, 2013 and 2012.
	Foreign Currency and Operations
	The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign subsidiaries is the local currency. The financial statements of these subsidiaries are translated into U.S. dollars using exchange rates in effect at the balance sheet date for assets and liabilities and average exchange rates during the period for revenues and expenses. The resulting translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ equity. Transaction gains and losses in currencies other than the functional currency are included in other income (expense) in the consolidated statements of operations. Amounts resulting from foreign currency transactions were not material for the three and nine months ended September 30, 2012 and 2013.
	Accumulated Other Comprehensive Income (Loss)
	Comprehensive income (loss) includes the Company’s net income (loss) as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. Other comprehensive income (loss) includes foreign currency translation adjustments and net unrealized gains and losses on investments classified as available-for-sale securities. Amounts reclassified out of accumulated other comprehensive income (loss) for the three and nine months ended September 30, 2012 and 2013 were not material.

	Revenue Recognition
	The Company derives its revenues from subscription arrangements and related services permitting customers to access and utilize the Company’s cloud-based software. The Company also derives revenues from news distribution services sold separately from its subscription arrangements. The Company recognizes revenue when there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company allocates consideration to each deliverable in multiple element arrangements based on the relative selling prices and recognizes revenue as the respective services are delivered or performed.
	The Company’s separate units of accounting consist of its subscription services, news distribution services and professional services. These elements generally include access to the Company’s cloud-based software, hosting services, content and content updates and customer support. The Company’s subscription agreements typically are non-cancelable, though customers have the right to terminate their agreements for cause if the Company materially breaches its obligations under the agreement. Subscription agreements do not provide customers the right to take possession of the software at any time.
	The Company also distributes individual news releases to the Internet which are indexed by major search engines and distributed directly to various news sites, journalists and other key constituents. The Company recognizes revenue on a per-transaction basis when the press releases are made available to the public.
	The Company’s professional services primarily consist of data migration, custom development and training. The Company’s cloud-based software does not require significant modification and customization services.
	The Company established vendor-specific objective evidence (VSOE) of the fair value for the selling price for certain of its news distribution services as the selling price for a substantial majority of stand-alone sales fall within a narrow range around the median selling price. The Company determined third-party evidence (TPE) of selling price is not available for any of its services due to differences in the features and functionality compared to competitors’ products. Therefore, the Company uses its estimated selling prices (ESP) for the remaining deliverables by analyzing multiple factors such as historical pricing trends, discounting practices, gross margin objectives and other market conditions.
	Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenues.
	Deferred Revenue
	Deferred revenue consists of payments received from or billings to customers in advance of revenue recognition. Deferred revenue to be recognized in the succeeding twelve month period is included in current deferred revenue with the remaining amounts included in non-current deferred revenue.
	Sales Commissions
	Sales commissions are expensed when a subscription agreement is executed by the customer.
	Stock-Based Compensation
	The Company’s share-based arrangements include stock option awards and restricted stock awards. The Company recognizes compensation expense for its equity awards on a straight-line basis over the requisite service period of the award based on the estimated portion of the award that is expected to vest and applies estimated forfeiture rates based on analyses of historical data, including termination patterns and other factors. Stock options granted have a 10-year term and generally vest annually over a four-year period. Restricted stock awards generally vest annually over a four-year period. The Company’s outstanding equity awards include stock option awards and restricted stock awards.
	The Company uses the quoted closing market price of its common stock on the grant date to measure the fair value of restricted stock awards and the Black-Scholes option pricing model to measure the fair value of stock option awards. The Company uses the daily historical volatility of its stock price over the expected life of the options to calculate the expected volatility. The Company uses a combination of its historical exercise data with expected future exercise patterns using the average midpoint between vesting and the contractual term to determine the expected term of option awards. The risk-free interest rate is based on the rate on U.S. Treasury securities with maturities consistent with the estimated expected term of the awards. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero.

	Income Taxes
	Income taxes are determined utilizing the asset and liability method whereby deferred tax assets and liabilities are recognized for deductible temporary differences between the respective reported amounts and tax bases of assets and liabilities, as well as for operating loss and tax-credit carryforwards. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.
	As of December 31, 2012 and September 30, 2013, the Company maintained a full valuation allowance on its U.S. and certain of its foreign deferred tax assets because management determined that it was more likely than not that it will not realize the benefits of its U.S. and certain of its foreign deferred tax assets.
	The Company’s federal and state NOL carryforwards and tax credits are subject to annual limitations under Sections 382 and 383 of Internal Revenue Code. The limitations imposed under Sections 382 and 383 will not preclude the Company from realizing these NOLs and tax credits but may operate to limit their utilization of the NOLs and tax credits in any given tax year in the event that the Company’s federal and state taxable income exceeds the limitation imposed by Sections 382 and 383.
	The Company’s estimates related to liabilities for uncertain tax positions require it to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. If it determines it is more likely than not that a tax position will be sustained based on its technical merits, the Company records the impact of the position in its consolidated financial statements at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. The estimates are updated at each reporting date based on the facts, circumstances and information available. The Company is also required to assess at each reporting date whether it is reasonably possible that any significant increases or decreases to its unrecognized tax benefits will occur during the next twelve months. The Company files income tax returns in the U.S. federal jurisdictions and various state and foreign jurisdictions and is subject to U.S. federal, state, and foreign tax examinations for years ranging from 2003 to 2012.
	Earnings Per Share
	Basic net income or loss per share attributable to common stockholders is computed by dividing net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Nonvested shares of restricted stock are not included in the computation of basic net income per share until vested. The Company’s outstanding grants of restricted stock do not contain non-forfeitable dividend rights. Diluted net income per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, nonvested shares of restricted stock and shares of redeemable convertible preferred stock are considered to be common stock equivalents.
	As the Company has issued shares of Series A redeemable convertible preferred stock that participate in dividends with the common stock, the Company is required to apply the two-class method to compute the net income per share attributable to common stockholders. In periods of sufficient earnings, the two-class method assumes an allocation of undistributed earnings to both participating stock classes.
	For the three and nine months ended September 30, 2012 and 2013, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, nonvested shares of restricted stock and redeemable convertible preferred stock was not included in the calculation of diluted loss per share as the effect would be anti-dilutive. For the three and nine months ended September 30, 2012 and 2013, diluted earnings per share excluded the impact of 2,669,373 and 3,306,798 outstanding stock options, respectively, and 1,111,991 and 952,930 nonvested shares of restricted stock, respectively and 1,000,000 shares of Series A redeemable convertible preferred stock as the result would be anti-dilutive.
	Segment Data
	The Company’s chief operating decision maker manages the Company’s operations on a consolidated basis for purposes of assessing performance and making operating decisions. Accordingly, the Company reports on its business as one segment.
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board issued an update regarding the reporting of amounts reclassified out of accumulated other comprehensive income. The update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component either on the face of the financial statements or in the notes thereto. The amendments in this update are effective prospectively for reporting periods beginning after December 15, 2012. The adoption did not have a material impact on the Company’s financial statements.

	Cash equivalents and short-term investments are classified within Level 1 of the fair value hierarchy since they are valued using quoted market prices or other readily available market information.

	The Company incurred contingent consideration liabilities in connection with its acquisition of North Venture Partners, LLC (North Social) in February 2011. Contingent consideration liabilities are classified as Level 3 of the fair value hierarchy since they are valued using unobservable inputs. The contingent consideration liability represented the fair value of the additional cash consideration payable that was contingent upon the achievement of certain financial and performance milestones through respective target dates in 2012 and 2013. For the nine months ended September 30, 2012 and 2013, the additional expense of $696,000 and $3.5 million, respectively, was included in general and administrative expenses in the consolidated statements of operations. During the nine months ended September 30, 2013, the fair value of the contingent consideration was adjusted based on the final earn-out calculations which were impacted by higher revenues in the first quarter of 2013 resulting from the increase in the number of North Social subscription customers due to additional marketing efforts near the conclusion of the earn-out period. The remaining liability for contingent consideration was paid in the second quarter of 2013.

	Revolving Credit Facility
	On February 27, 2012, the Company established a $15.0 million revolving credit facility (Revolver) with a major lending institution which was originally available for use until February 27, 2013. In February 2013, the Revolver was amended to extend the availability for use until April 15, 2014. The Revolver is intended to be used for general working capital purposes and to provide increased liquidity and financial flexibility and bears interest equal to the BBA LIBOR Daily Floating Rate plus 2.25%. In addition, the Company pays a monthly fee equal to 0.4% on any unused funds under the Revolver. As collateral for extension of this credit, the Company and certain of its subsidiaries granted security interests in favor of the institution of substantially all of their assets, and the Company pledged the stock of its directly owned domestic subsidiaries and 65% of the shares of its foreign subsidiaries. As of September 30, 2013, there were no outstanding borrowings, however, the Revolver was reduced by the Company’s outstanding letters of credit of $1.3 million. As such, the Company had $13.7 million available to borrow under the Revolver.
	Term Loans
	During the nine months ended September 30, 2013, the Company entered into loan agreements with the State of Maryland and Prince George’s County totaling $600,000 with terms ending December 31, 2020 and December 31, 2016, respectively. The proceeds of the loans were used in the expansion of its corporate headquarters in Beltsville, Maryland. The borrowings bear interest at 3.0%. The conditions of the loans stipulate that principal and related accrued interest be forgiven if specified employment levels are achieved and maintained and the Company maintains the Beltsville, Maryland location as the corporate headquarters through the end of the loans. As of September 30, 2013, the Company has met the conditions of the loans, however, the conditions are required to be met throughout the term of the loan and, as such, the loan is recorded as a long-term liability. The outstanding balance of these loans is included in notes payable and capital lease obligations, net of current portion.

	Preferred Stock
	The Company’s Certificate of Incorporation authorizes 10,000,000 undesignated shares of preferred stock. The Company’s Board of Directors (Board) is authorized to establish one or more classes or series from the undesignated shares, to designate each share or class or series, and to fix the relative rights and preferences of each class or series, which rights and preferences may be superior to those of any of the common shares. In February 2012, the Board designated 1,000,000 shares of the Company’s authorized preferred stock as Series A convertible preferred stock in connection with the acquisition of iContact. On February 24, 2012, the Company issued 1,000,000 shares of Series A Redeemable Convertible Preferred Stock (Series A Preferred Stock). In May 2013, the Board designated 100,000 shares of the Company’s authorized preferred stock as Series B Junior Participating Preferred Stock (Series B Preferred Stock), however, no shares of Series B Preferred Stock are issued and outstanding.
	Series A Redeemable Convertible Preferred Stock
	In connection with the acquisition of iContact in February 2012, the Company issued 1,000,000 shares of Series A Preferred Stock with a deemed fair value at issuance of $77.5 million. The Company does not adjust the carrying value to the redemption amount of the convertible preferred stock as the carrying amount exceeds the redemption amount. There have been no changes to the recorded amount of the Series A Preferred Stock since the issuance of the shares.
	Each share of the Series A Preferred Stock has a liquidation preference equal to the greater of $77.30 (subject to appropriate adjustment in the event of any stock dividend, stock split, combination, or other similar recapitalization affected the Series A Preferred Stock) or the value of the shares of common stock that would be issued in respect thereof upon conversion of such share of Series A Preferred Stock. The Series A Preferred Stock does not provide for interest and is entitled to participate in any dividends declared on the Company’s common stock on an as-converted basis. On February 24, 2017, the Company will be required to redeem each issued and outstanding share of the Series A Preferred Stock for $77.30 per share from its legally available funds, or such lesser amount of shares as it may then redeem under Delaware law. Each share of the Series A Preferred Stock is convertible into shares of the Company’s common stock at any time at the option of the holder. For conversions occurring on or before February 24, 2017, each share of Series A Preferred Stock will be convertible into 3.0256 shares of common stock (subject to customary adjustments). On and after February 25, 2017, each share of the Series A Preferred Stock which has not been redeemed will be convertible into 3.3282 shares of common stock (subject to customary adjustments).
	The holders of Series A Preferred Stock vote on an as-converted basis with the common stock, voting together as a single class, provided that the holders of the Series A Preferred Stock are entitled to vote separately as a class on certain matters affecting the Series A Preferred Stock. If any shares of Series A Preferred Stock are outstanding on or after February 24, 2017, the holders of the Series A Preferred Stock will have the right to vote separately as a class on additional actions by the Company related to acquisitions, redemptions, dividends, capital stock, and indebtedness. In addition, for so long as the outstanding shares of Series A Preferred Stock continue to represent at least 5% of the total outstanding shares of the Company’s common stock, calculated assuming the conversion of all outstanding shares of Series A Preferred Stock into shares of common stock, the holders of the Series A Preferred Stock, voting as a separate class, will have the exclusive right to elect one director to the Company’s Board of Directors (Series A Director).
	In connection with the acquisition of iContact, the Company also entered into, on February 24, 2012, an Investor Rights Agreement (Investor Rights Agreement) whereby the holders of the Series A Preferred Stock have the right to nominate a director to the Company’s Board for as long as they hold 5% or more of the Company’s issued and outstanding capital stock (which nominee shall be the Series A Director for so long as the holders of Series A Preferred Stock have the right to elect the Series A Director pursuant to the Certificate of Designation). In addition, subject to the terms and conditions of the Investor Rights Agreement, the holders of the Series A Preferred Stock shall have demand and piggyback registration rights and the right to participate in certain repurchases of common stock by the Company.
	Stockholder Rights Plan
	On May 13, 2013, the Board authorized and declared a dividend distribution of one preferred stock purchase right (Right) for each outstanding share of the Company’s common stock and 3.0256 Rights for each outstanding share of the Company’s Series A Convertible Preferred Stock to stockholders of record at the close of business on May 13, 2013.
	Each Right entitles registered holders to purchase from the Company one one-thousandth of a share of the Company’s Series B Junior Participating Preferred Stock at a price of $46.00 per one one-thousandth of a share, subject to adjustment. The definitive terms of the Rights are set forth in a Rights Agreement, dated May 13, 2013. The Rights will be exercisable only if a person or group acquires 20% or more of the Company’s outstanding common stock (subject to certain exceptions), or if a person or group announces a tender or exchange offer, resulting in beneficial ownership of 20% or more of the outstanding common stock. The Rights also will be exercisable if a person or group that already beneficially owns or has the right to acquire on May 13, 2013, 20% or more of the Company’s outstanding common stock acquires additional shares equal to 1% or more of the Company’s then outstanding common stock (except in the case of a certain stockholder who, under limited circumstances, is permitted to beneficially own more than 20%, but less than 25%, of the Company’s outstanding common stock, subject to certain exceptions).
	The Board can redeem the Rights for $0.0001 per Right at any time prior to the earlier of the occurrence of a “trigger event” or the expiration date. Additionally, prior to an acquisition of 50% or more of the Company’s common stock, the Board may direct the mandatory exchange of the Rights (other than Rights owned by the acquiring person) at an exchange ratio of one newly issued share of common stock for each right.
	The Rights will expire on May 13, 2016 or 30 days after the Company’s 2014 annual meeting of stockholders if the continuation of the rights plan is not approved by the Company’s stockholders at its 2014 annual meeting, if not exercised or redeemed.
	Common Stock Repurchases
	The Board authorized a stock repurchase program for up to $60.0 million of the Company’s shares of common stock. The shares may be purchased from time to time in the open market. The Company did not purchase any shares of its common stock under the stock repurchase program for the nine months ended September 30, 2012 and 2013. During the nine months ended September 30, 2012 and 2013, the Company repurchased 142,191 and 34,040 shares of restricted stock that were withheld from employees to satisfy the minimum statutory tax withholding obligations of $3.1 million and $458,000, respectively, related to the taxable income recognized by these employees upon the vesting of their restricted stock awards.

	Basis of Presentation
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and include the accounts of Vocus, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. The consolidated balance sheet at December 31, 2012 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on March 11, 2013.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those related to the allowance for doubtful accounts, software development costs, useful lives of property, equipment and software, intangible assets and goodwill, contingent liabilities, self-insurance, revenue recognition, fair value of stock-based awards and income taxes, among others. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities as well as the reported amounts of revenues and expenses during the period. Actual results could differ from these estimates.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company considers all highly liquid investments with original maturity dates of three months or less at the time of purchase to be cash equivalents.
Investments	'
	Investments
	Management determines the appropriate classification of investments at the time of purchase and evaluates such a determination as of each balance sheet date. The Company’s investments were classified as available-for-sale securities and were stated at fair value at December 31, 2012. Realized gains and losses are included in other income (expense) based on the specific identification method. Realized gains or losses for the three and nine months ended September 30, 2012, and 2013 were not material. Net unrealized gains and losses on available-for-sale securities are reported as a component of other comprehensive income (loss), net of tax. As of December 31, 2012, the net unrealized gains or losses on available-for-sale securities were not material. The Company regularly monitors and evaluates the fair value of its investments to identify other-than-temporary declines in value.
Fair Value Measurements	'
	Fair Value Measurements
	The Company measures certain financial assets at fair value pursuant to a fair value hierarchy based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels:


	Level 1	—	Inputs are quoted prices in active markets for identical assets or liabilities.

	Level 2	—	Inputs are quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

	Level 3	—	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	Estimates are used to determine the amount of the allowance for doubtful accounts necessary to reduce accounts receivable to the estimated net realizable value. These estimates are made by analyzing the status of significant past-due receivables and by establishing provisions for estimated losses by analyzing current and historical bad debt trends. The Company charges off uncollectible amounts against the allowance for doubtful accounts in the period in which it determines they are uncollectible. Actual collection experience has not varied significantly from prior estimates.
Long-Lived Assets	'
	Long-Lived Assets
	Long-lived assets include property, equipment and software and intangible assets with finite lives. Intangible assets consist of customer relationships, trade names and purchased technology acquired in business combinations. Intangible assets are amortized using the straight-line method over their estimated useful lives ranging from two to seven years. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If an impairment indicator is present, the Company evaluates recoverability by a comparison of the carrying amount of the assets to future undiscounted net cash flows expected to be generated by the assets. If the assets are impaired, the impairment recognized is measured by the amount by which the carrying amount exceeds the estimated fair value of the assets. Impairment charges for long-lived assets for the nine months ended September 30, 2012 were $709,000. There were no impairment charges for long-lived assets for the nine months ended September 30, 2013.
Business Combinations	'
	Business Combinations
	The Company has completed acquisitions of businesses that have resulted in the recording of goodwill and identifiable definite-lived intangible assets. The Company recognizes all of the assets acquired, liabilities assumed and contingent consideration at their fair values on the acquisition date. The Company uses significant estimates and assumptions, including fair value estimates, as of the acquisition date and refines those estimates that are provisional, as necessary, during the measurement period. The measurement period is the period after the acquisition date, not to exceed one year, in which new information may be gathered about facts and circumstances that existed as of the acquisition date to adjust the provisional amounts recognized. Measurement period adjustments are applied retrospectively. All other adjustments are recorded to the consolidated statements of operations. Acquisition-related costs are expensed as incurred separately from the acquisition and generally are included in general and administrative expenses in the consolidated statements of operations.
Goodwill	'
	Goodwill
	Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. The Company performs its annual impairment assessment on November 1, or whenever events or circumstances indicate impairment may have occurred. The Company operates under one reporting unit, and as a result, evaluates goodwill impairment based on the fair value of the Company as a whole. The Company did not record any impairment charges for goodwill during the nine months ended September 30, 2013 and 2012.
Foreign Currency and Operations	'
	Foreign Currency and Operations
	The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign subsidiaries is the local currency. The financial statements of these subsidiaries are translated into U.S. dollars using exchange rates in effect at the balance sheet date for assets and liabilities and average exchange rates during the period for revenues and expenses. The resulting translation adjustments are included in accumulated other comprehensive income (loss), a separate component of stockholders’ equity. Transaction gains and losses in currencies other than the functional currency are included in other income (expense) in the consolidated statements of operations. Amounts resulting from foreign currency transactions were not material for the three and nine months ended September 30, 2012 and 2013.
Accumulated Other Comprehensive Income (Loss)	'
	Accumulated Other Comprehensive Income (Loss)
	Comprehensive income (loss) includes the Company’s net income (loss) as well as other changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. Other comprehensive income (loss) includes foreign currency translation adjustments and net unrealized gains and losses on investments classified as available-for-sale securities. Amounts reclassified out of accumulated other comprehensive income (loss) for the three and nine months ended September 30, 2012 and 2013 were not material.
Revenue Recognition	'
	Revenue Recognition
	The Company derives its revenues from subscription arrangements and related services permitting customers to access and utilize the Company’s cloud-based software. The Company also derives revenues from news distribution services sold separately from its subscription arrangements. The Company recognizes revenue when there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company allocates consideration to each deliverable in multiple element arrangements based on the relative selling prices and recognizes revenue as the respective services are delivered or performed.
	The Company’s separate units of accounting consist of its subscription services, news distribution services and professional services. These elements generally include access to the Company’s cloud-based software, hosting services, content and content updates and customer support. The Company’s subscription agreements typically are non-cancelable, though customers have the right to terminate their agreements for cause if the Company materially breaches its obligations under the agreement. Subscription agreements do not provide customers the right to take possession of the software at any time.
	The Company also distributes individual news releases to the Internet which are indexed by major search engines and distributed directly to various news sites, journalists and other key constituents. The Company recognizes revenue on a per-transaction basis when the press releases are made available to the public.
	The Company’s professional services primarily consist of data migration, custom development and training. The Company’s cloud-based software does not require significant modification and customization services.
	The Company established vendor-specific objective evidence (VSOE) of the fair value for the selling price for certain of its news distribution services as the selling price for a substantial majority of stand-alone sales fall within a narrow range around the median selling price. The Company determined third-party evidence (TPE) of selling price is not available for any of its services due to differences in the features and functionality compared to competitors’ products. Therefore, the Company uses its estimated selling prices (ESP) for the remaining deliverables by analyzing multiple factors such as historical pricing trends, discounting practices, gross margin objectives and other market conditions.
	Sales and other taxes collected from customers to be remitted to government authorities are excluded from revenues.
Deferred Revenue	'
	Deferred Revenue
	Deferred revenue consists of payments received from or billings to customers in advance of revenue recognition. Deferred revenue to be recognized in the succeeding twelve month period is included in current deferred revenue with the remaining amounts included in non-current deferred revenue.
Sales Commissions	'
	Sales Commissions
	Sales commissions are expensed when a subscription agreement is executed by the customer.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company’s share-based arrangements include stock option awards and restricted stock awards. The Company recognizes compensation expense for its equity awards on a straight-line basis over the requisite service period of the award based on the estimated portion of the award that is expected to vest and applies estimated forfeiture rates based on analyses of historical data, including termination patterns and other factors. Stock options granted have a 10-year term and generally vest annually over a four-year period. Restricted stock awards generally vest annually over a four-year period. The Company’s outstanding equity awards include stock option awards and restricted stock awards.
	The Company uses the quoted closing market price of its common stock on the grant date to measure the fair value of restricted stock awards and the Black-Scholes option pricing model to measure the fair value of stock option awards. The Company uses the daily historical volatility of its stock price over the expected life of the options to calculate the expected volatility. The Company uses a combination of its historical exercise data with expected future exercise patterns using the average midpoint between vesting and the contractual term to determine the expected term of option awards. The risk-free interest rate is based on the rate on U.S. Treasury securities with maturities consistent with the estimated expected term of the awards. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero.
Income Taxes	'
	Income Taxes
	Income taxes are determined utilizing the asset and liability method whereby deferred tax assets and liabilities are recognized for deductible temporary differences between the respective reported amounts and tax bases of assets and liabilities, as well as for operating loss and tax-credit carryforwards. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.
	As of December 31, 2012 and September 30, 2013, the Company maintained a full valuation allowance on its U.S. and certain of its foreign deferred tax assets because management determined that it was more likely than not that it will not realize the benefits of its U.S. and certain of its foreign deferred tax assets.
	The Company’s federal and state NOL carryforwards and tax credits are subject to annual limitations under Sections 382 and 383 of Internal Revenue Code. The limitations imposed under Sections 382 and 383 will not preclude the Company from realizing these NOLs and tax credits but may operate to limit their utilization of the NOLs and tax credits in any given tax year in the event that the Company’s federal and state taxable income exceeds the limitation imposed by Sections 382 and 383.
	The Company’s estimates related to liabilities for uncertain tax positions require it to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. If it determines it is more likely than not that a tax position will be sustained based on its technical merits, the Company records the impact of the position in its consolidated financial statements at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. The estimates are updated at each reporting date based on the facts, circumstances and information available. The Company is also required to assess at each reporting date whether it is reasonably possible that any significant increases or decreases to its unrecognized tax benefits will occur during the next twelve months. The Company files income tax returns in the U.S. federal jurisdictions and various state and foreign jurisdictions and is subject to U.S. federal, state, and foreign tax examinations for years ranging from 2003 to 2012.
Earnings Per Share	'
	Earnings Per Share
	Basic net income or loss per share attributable to common stockholders is computed by dividing net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Nonvested shares of restricted stock are not included in the computation of basic net income per share until vested. The Company’s outstanding grants of restricted stock do not contain non-forfeitable dividend rights. Diluted net income per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock, nonvested shares of restricted stock and shares of redeemable convertible preferred stock are considered to be common stock equivalents.
	As the Company has issued shares of Series A redeemable convertible preferred stock that participate in dividends with the common stock, the Company is required to apply the two-class method to compute the net income per share attributable to common stockholders. In periods of sufficient earnings, the two-class method assumes an allocation of undistributed earnings to both participating stock classes.
	For the three and nine months ended September 30, 2012 and 2013, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, nonvested shares of restricted stock and redeemable convertible preferred stock was not included in the calculation of diluted loss per share as the effect would be anti-dilutive. For the three and nine months ended September 30, 2012 and 2013, diluted earnings per share excluded the impact of 2,669,373 and 3,306,798 outstanding stock options, respectively, and 1,111,991 and 952,930 nonvested shares of restricted stock, respectively and 1,000,000 shares of Series A redeemable convertible preferred stock as the result would be anti-dilutive.
Segment Data	'

	The Company’s chief operating decision maker manages the Company’s operations on a consolidated basis for purposes of assessing performance and making operating decisions. Accordingly, the Company reports on its business as one segment.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board issued an update regarding the reporting of amounts reclassified out of accumulated other comprehensive income. The update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component either on the face of the financial statements or in the notes thereto. The amendments in this update are effective prospectively for reporting periods beginning after December 15, 2012. The adoption did not have a material impact on the Company’s financial statements.
