Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in these Notes to Consolidated Financial Statements.
	Principles of Consolidation
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, which are comprised of KnowledgeStorm, Inc., Bitpipe, Inc., TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited, TechTarget (Beijing) Information Technology Consulting Co., Ltd., TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS and TechTarget Germany GmbH. KnowledgeStorm, Inc. and Bitpipe, Inc. feature websites that provide in-depth vendor generated content targeted to corporate IT professionals. TechTarget Securities Corporation is a Massachusetts security corporation incorporated in 2004. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TechTarget (HK) Limited (“TTGT HK”) is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. Additionally, through its wholly-owned subsidiaries, TTGT HK and TechTarget (Beijing) Information Technology Consulting Co., Ltd. (“TTGT Consulting”, incorporated on December 16, 2011), the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”) on November 27, 2007. TechTarget (Australia) Pty Ltd. (incorporated on December 15, 2011) and TechTarget (Singapore) Pte Ltd. (incorporated on February 12, 2012) are the entities through which the Company does business in Australia and Singapore, respectively; E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH (incorporated on June 6, 2014), both wholly-owned subsidiaries of TechTarget Limited, are entities through which the Company does business in France and Germany, respectively.
	PRC laws and regulations prohibit or restrict foreign ownership of Internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of their residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. On December 31, 2011, TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise (“WFOE”), TTGT Consulting. The WFOE is established and existing under the laws of the PRC, and is wholly owned by TTGT HK.
	Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through the WFOE, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to the WFOE. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions between the Company, its subsidiaries, and KWIT have been eliminated in consolidation.
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (generally accepted accounting principles, or “GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. All adjustments, which, in the opinion of management, are considered necessary for a fair presentation of the results of operations for the periods shown, are of a normal recurring nature and have been reflected in the consolidated financial statements. The results of operations for the periods presented are not necessarily indicative of results to be expected for any other interim periods or for the full year. The information included in these consolidated financial statements should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report and the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	Reclassifications
	Beginning in the third quarter of 2014, the Company changed its presentation of transactional gains and losses arising from the impact of currency exchange rate fluctuations on transactions in foreign currency that is different from the local functional currency in order to better reflect the non-operating nature of these gains and losses, and is now including them in Other Income (Expense) on the Consolidated Statements of Operations and Comprehensive Income (Loss). Previously, these gains and losses were included in the Company’s operating expenses as General and Administrative expense. Amounts in the prior periods’ financial statements have been reclassified to conform to the current presentation. In the three months ended September 30, 2013, this resulted in an increase to Other Income and an increase in General and Administrative expense equal to $0.1 million and for the nine months ended September 30, 2013, this resulted in an increase to Other Expense and a decrease in General and Administrative expense amounting to $0.2 million. In the first half of 2014, the Company recorded gains of $0.1 million as reductions to General and Administrative expense that have now been reclassified as Other (Expense) Income for the nine months ended September 30, 2014.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
	Revenue Recognition
	The Company generates substantially all of its revenue from the sale of targeted advertising campaigns, which are delivered via its network of websites, and events. Revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, the service is performed and collectability of the resulting receivable is reasonably assured.
	The majority of the Company’s online media sales involve multiple product offerings, which are described in more detail below. Because neither vendor-specific objective evidence of fair value nor third party evidence of fair value exists for all elements in the Company’s bundled product offerings, the Company uses an estimated selling price which represents management’s best estimate of the stand-alone selling price for each deliverable in an arrangement. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available media inventory, pricing strategies and market conditions. The Company believes the use of the best estimate of selling price allows revenue recognition in a manner consistent with the underlying economics of the transaction. The Company uses the relative selling price method to allocate consideration at the inception of the arrangement to each deliverable in a multiple element arrangement. The relative selling price method allocates any discount in the arrangement proportionately to each deliverable on the basis of the deliverable’s best estimated selling price. Revenue is then recognized as delivery occurs.

	The Company evaluates all deliverables of an arrangement at inception and each time an item is delivered, to determine whether they represent separate units of accounting. Based on this evaluation, the arrangement consideration is measured and allocated to each of these elements.
	Online Media. Revenue for lead generation campaigns is recognized as follows:
	Lead generation campaigns all offer the Activity Intelligence™ Dashboard (the “Dashboard”). For duration-based campaigns, revenue is recognized ratably over the duration of the campaigns, which is usually less than six months. Lead generation offerings may also include an additional service, TechTarget Re-Engage (formerly called Nurture & Qualify), in which case revenue is recognized ratably over the period of the campaign as a combined unit of accounting. As part of these lead generation campaign offerings, the Company will guarantee a minimum number of qualified leads to be delivered over the course of the advertising campaign. The Company determines the content necessary to achieve performance guarantees. Scheduled end dates of advertising campaigns sometimes need to be extended, pursuant to the terms of the arrangement, to satisfy lead guarantees. The Company estimates a revenue reserve necessary to adjust revenue recognition for extended advertising campaigns. These estimates are based on the Company’s experience in managing and fulfilling these offerings. The customer has cancellation privileges which generally require advance notice by the customer and require proportional payment by the customer for the portion of the campaign period provided by the Company. Additionally, the Company offers sales incentives to certain customers, primarily in the form of volume rebates, which are classified as a reduction of revenues and are calculated based on the terms of the specific customer’s contract. The Company accrues for these sales incentives based on contractual terms and historical experience.
	The Company recognizes revenue on contracts where pricing is based on cost per lead in the period during which the leads are delivered to its customers.
	Revenue for other significant online media offerings is recognized as follows:

		•	IT Deal Alert™. This suite of products includes Qualified Sales Opportunities and Account Watch. Qualified Sales Opportunities revenue is recognized when the opportunity is delivered to the Company’s customer, and Account Watch revenue is recognized ratably over the duration of the service.

		•	Custom Content Creation. Custom content revenue is recognized when the creation is completed and delivered to the customer, with the exception of microsites which are recognized over the period during which they are live.

		•	Content Sponsorships. Content sponsorship revenue is recognized ratably over the period in which the related content asset is available on the Company’s websites.

		•	List Rentals. List rental revenue is recognized in the period in which the delivery of the list is made to the Company’s customer.

		•	Banners. Banner revenue is recognized in the period in which the banner impressions, engagements or clicks occur.

		•	Third Party Revenue Sharing Arrangements. Revenue from third party revenue sharing arrangements is recognized on a net basis in the period in which the services are performed. For certain third party agreements where the Company is the primary obligor, revenue is recognized on a gross basis in the period in which the services are performed.
	Event Sponsorships. Revenue from vendor-sponsored events, whether sponsored exclusively by a single vendor or in a multi-vendor sponsored event, is recognized upon completion of the event in the period the event occurs. The majority of the Company’s events are free to qualified attendees; however, certain events are based on a paid attendee model. The Company recognizes revenue for paid attendee events upon completion of the event.
	Amounts collected or billed prior to satisfying the above revenue recognition criteria are recorded as deferred revenue. The Company excludes from its deferred revenue and accounts receivable balances amounts for which it has billed in advance prior to the start of a campaign or the delivery of services.

	Fair Value of Financial Instruments
	Financial instruments consist of cash and cash equivalents, short and long-term investments, accounts receivable, accounts payable and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments with the exception of contingent consideration approximates their estimated fair values. The fair value of contingent consideration was estimated using a discounted cash flow method described in Note 5.
	Long-lived Assets, Goodwill and Indefinite-lived Intangible Assets
	Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired.
	Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from three to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has only one reporting segment, it has been determined that there is only one reporting unit and goodwill is tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two step process required by ASC 350, Intangibles – Goodwill and Other (“ASC 350”). The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment are present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to its carrying value to determine the amount of the impairment loss, if any. As of December 31, 2013, there were no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin.
	Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets was impaired. The Company did not have any intangible assets with indefinite lives as of September 30, 2014 or December 31, 2013.
	Allowance for Doubtful Accounts
	The Company offsets gross trade accounts receivable with an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in their existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense.
	Property and Equipment
	Property and equipment is stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over their estimated useful lives.

	Internal-Use Software and Website Development Costs
	The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The estimated useful life of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $0.8 million and $0.9 million for the three months ended September 30, 2014 and 2013, respectively, and $2.5 million and $2.9 million for the nine months ended September 30, 2014 and 2013, respectively.
	Income Taxes
	The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes.
	The Company recognizes any interest and penalties related to unrecognized tax benefits in income tax expense.
	Stock-Based Compensation
	The Company has two stock-based compensation plans which are more fully described in Note 11. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Statement of Operations and Comprehensive Income (Loss) predominantly using the straight-line method over the vesting period of the award. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option awards.
	Comprehensive Income (Loss)
	Comprehensive income (loss) includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company’s comprehensive income (loss) includes changes in the fair value of the Company’s unrealized gains (losses) on available for sale securities and foreign currency translation.
	Foreign Currency
	The functional currency for each of the Company’s subsidiaries is each country’s local currency. All assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss).
	Net Income (Loss) Per Share
	Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock awards outstanding during the period. Because the holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents, the Company does not consider these awards to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested restricted stock awards outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock awards is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense and assumed tax benefit of stock options and restricted stock awards that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock awards.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016 (January 1, 2017 for the Company); early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. The Company has not determined the potential effects on the consolidated financial statements.

Fair Value Measurements	'
	3. Fair Value Measurements
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, short- and long-term investments and contingent consideration. The fair value of these financial assets and liabilities was determined based on three levels of input as follows:

		•		Level 1. Quoted prices in active markets for identical assets and liabilities;

		•		Level 2. Observable inputs other than quoted prices in active markets; and

		•		Level 3. Unobservable inputs.
	The fair value hierarchy of the Company’s financial assets and liabilities carried at fair value and measured on a recurring basis is as follows:

	-3	Valuation techniques and Level 3 inputs used to estimate the fair value of contingent consideration payable in connection with the LeMag acquisition in December, 2012 are described in Note 5. During the nine months ended September 30, 2014 and 2013 the contingent consideration increased by approximately $253 and $221, respectively, when it was remeasured to fair value. The remainder of the change in this balance was caused by amortization of a discount on the installment payments and foreign currency fluctuations.

	4. Cash, Cash Equivalents and Investments
	Cash and cash equivalents consist of highly liquid investments with maturities of three months or less at date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Cash and cash equivalents consisted of the following:


		September 30,		December 31,
		2014		2013

	Money market funds		3,358		1,607

	Total cash and cash equivalents	$	25,752	$	15,412

	The Company’s short- and long-term investments are accounted for as available for sale securities. These investments are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity, net of tax. The unrealized gain, net of taxes, was $11 and $10 as of September 30, 2014 and December 31, 2013, respectively. Realized gains and losses on the sale of these investments are determined using the specific identification method. There were no realized gains or losses during the three or nine months ended September 30, 2014 or 2013.
	Short- and long-term investments consisted of the following:


		September 30, 2014

	The Company had three debt securities in an unrealized loss position at September 30, 2014. The unrealized loss on those securities was approximately $5 and the fair value was $4.8 million. As of September 30, 2014, the Company does not consider these investments to be other-than-temporarily impaired.
	Municipal and government-agency bonds have contractual maturity dates that range from October 2014 to July 2017. All income generated from these investments is recorded as interest income.

	5. Acquisition
	LeMagIT
	On December 17, 2012 the Company purchased all of the outstanding shares of its French partner, E-Magine Médias SAS, for approximately $2.2 million in cash plus a potential future earnout valued at $0.7 million at the time of the acquisition. Approximately $1.2 million of the cash payment was made at closing, with the remainder due in two equal installments in fiscal years 2013 and 2014. The third installment is subject to certain revenue growth targets and may be reduced based on actual results. If all targets are met, the total purchase price, including the earnout, shall not exceed $5.2 million, depending on exchange rates at the time of calculation. The installment payments have been recorded at present value using a discount rate of 10%; the discount will be amortized to interest through the payment dates. The second installment was paid in 2013. The third installment, to be paid in the fourth quarter of 2014, is included in accrued liabilities in the Company’s consolidated balance sheet; the earnout is included in non-current liabilities.
	Contingent consideration related to this acquisition consists of a potential earnout as well as the final payment, both of which are subject to future revenue targets and may differ from the amounts that are ultimately payable based on the final calculations. In valuing the contingent consideration it was determined that fair value adjustments were necessary to appropriately reflect the inherent risk and related time value of money associated with these potential payments. Accordingly, discount rates of 28% and 10% were used for the earnout and the final payment, respectively. The calculation of these fair values required the use of significant inputs that are not observable in the market and thus represent a Level 3 fair value measurement as defined in ASC 820, Fair Value Measurements and Disclosures. The significant inputs in the Level 3 measurements not supported by market activity include estimated future revenues as well as the rates used to discount them.

	Intangible assets are amortized over their estimated useful lives, which currently range from three to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use. The remaining amortization expense will be recognized over a weighted-average period of approximately 2.28 years. Amortization expense was $0.5 million for each of the three months ended September 30, 2014 and 2013, and $1.4 million and $1.8 million for the nine months ended September 30, 2014 and 2013, respectively. Amortization expense is recorded within operating expenses as the intangible assets consist of customer-related assets and website traffic that the Company considers to be in support of selling and marketing activities. The Company wrote off $5.8 million of fully amortized intangible assets in the first nine months of 2014; the Company did not write off any amortized intangible assets in the first nine months of 2013.

	The Company expects amortization expense of intangible assets to be as follows:

	The Company’s $5.0 million revolving credit facility was amended in August 2011, extending its term and adjusting certain other financial terms and covenants. Unless earlier payment is required by an event of default, all principal and unpaid interest will be due and payable on August 31, 2016. At the Company’s option, the Revolving Credit Facility (the “Credit Agreement”) bears interest at either the prime rate less 1.00% or the London Interbank Offered Rate (“LIBOR”) plus the applicable LIBOR margin. The applicable LIBOR margin is based on the ratio of total funded debt to earnings before interest, other income and expense, income taxes, depreciation, and amortization (“EBITDA”) for the preceding four fiscal quarters. As of September 30, 2014, the applicable LIBOR margin was 1.25%.

	The Company is also required to pay an unused line fee on the daily unused amount of the Credit Agreement at a per annum rate based on the ratio of total funded debt to EBITDA for the preceding four fiscal quarters. As of September 30, 2014, the per annum unused line fee rate was 0.20%.
	At September 30, 2014 and December 31, 2013 there were no amounts outstanding under the Credit Agreement. Pursuant to the Credit Agreement, there was a $1.0 million standby letter of credit (“Letter of Credit”) related to the Company’s corporate headquarters lease outstanding at September 30, 2014, bringing the Company’s available borrowings on the $5.0 million facility to $4.0 million.
	Borrowings under the Credit Agreement are collateralized by a security interest in substantially all assets of the Company. Covenants governing the Credit Agreement include the maintenance of certain financial ratios. At September 30, 2014, the Company was in compliance with all covenants under the Credit Agreement.
	In the third quarter of 2014, the Company paid $0.7 million in cash as a security deposit on its corporate headquarters lease. The Letter of Credit, which was also being held against the lease, was cancelled in October 2014.

	The Company conducts its operations in leased office facilities under various noncancelable operating lease agreements that expire through January 2020. In August 2009, the Company entered into an agreement to lease approximately 87,875 square feet of office space in Newton, Massachusetts. The lease commenced in February 2010 and has a term of ten years. The Company is receiving certain rent concessions over the life of the lease. In November 2010, the Newton lease was amended to include an additional 8,400 square feet of office space. The amended lease commenced in March 2011 and runs concurrently with the term of the original lease. The Company is receiving certain rent concessions over the life of the amended lease.
	Certain of the Company’s operating leases include lease incentives and escalating payment amounts and are renewable for varying periods. The Company is recognizing the related rent expense on a straight-line basis over the term of the lease taking into account the lease incentives and escalating lease payments.
	Future minimum lease payments under the Company’s noncancelable operating leases at September 30, 2014 are as follows:


	Years Ending December 31:	Minimum Lease
		Payments
		(Unaudited)
	2014 (October 1st – December 31st)	$	1,126

	The Company had an irrevocable standby letter of credit outstanding in the aggregate amount of $1.0 million as of September 30, 2014 that supported the lease the Company entered into in 2009 for its corporate headquarters.
	In the third quarter of 2014, the Company paid $0.7 million in cash as a security deposit on its corporate headquarters lease. The Letter of Credit, which was also being held against the lease, was cancelled in October 2014.
	Net Worth Tax Contingency
	In late March 2010, the Company received a letter from the Department of Revenue of the Commonwealth of Massachusetts (the “MA DOR”) requesting documentation demonstrating that TSC has been classified by the MA DOR as a Massachusetts security corporation. Following subsequent correspondence with the MA DOR and a settlement conference on March 22, 2011, the Company received a Notice of Assessment from the MA DOR with respect to additional excise taxes on net worth related to TSC. Based on the Company’s previous assessment that it was probable that the MA DOR would require an adjustment to correct TSC’s tax filings such that it will be treated as a Massachusetts business corporation for the applicable years, the Company has recorded a liability representing its best estimate at that time of the potential net worth tax exposure. The tax benefits available to a Massachusetts security corporation are comprised of (i) a different rate structure (1.32% on gross investment income vs. 9.5% on net income) (See Note 13) and (ii) exemption from the 0.26% excise tax on net worth. On August 17, 2011, the Company filed Applications for Abatement with the MA DOR. On January 6, 2012, the Company filed Petitions for Formal Procedure with the Massachusetts Appellate Tax Board. A trial took place on April 29, 2014; as of the date of this report no decision has been rendered. As of September 30, 2014 the Company has recorded a liability of approximately $260 to account for the tax differential in all open years, including penalties and interest.
	Litigation
	From time to time and in the ordinary course of business, the Company may be subject to various claims, charges, and litigation. At September 30, 2014 and December 31, 2013, the Company did not have any pending claims, charges, or litigation that it expects would have a material adverse effect on its consolidated financial position, results of operations, or cash flows.

	Stock Option Plans
	In September 1999, the Company approved a stock option plan (the “1999 Plan”) that provides for the issuance of up to 12,384,646 shares of common stock incentives. The 1999 Plan provides for the granting of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), and stock grants. These incentives may be offered to the Company’s employees, officers, directors, consultants, and advisors. ISOs may not be granted at less than fair market value on the date of grant, as determined by the Company’s Board of Directors (the “Board”). Each option shall be exercisable at such times and subject to such terms as determined by the Board; grants generally vest over a four year period, and expire no later than ten years after the grant date.
	In April 2007, the Board approved the 2007 Stock Option and Incentive Plan (the “2007 Plan”), which was approved by the stockholders of the Company and became effective upon the consummation of the Company’s IPO in May 2007. Effective upon the consummation of the IPO, no further awards were made pursuant to the 1999 Plan, but any outstanding awards under the 1999 Plan remain in effect and continue to be subject to the terms of the 1999 Plan. The 2007 Plan allows the Company to grant ISOs, NSOs, stock appreciation rights, deferred stock awards, restricted stock and other awards. Under the 2007 Plan, stock options may not be granted at less than fair market value on the date of grant, and grants generally vest over a four year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. The Company has reserved for issuance an aggregate of 2,911,667 shares of common stock under the 2007 Plan plus an additional annual increase to be added automatically on January 1 of each year, beginning on January 1, 2008, equal to the lesser of (a) 2% of the outstanding number of shares of common stock (on a fully-diluted basis) on the immediately preceding December 31 and (b) such lower number of shares as may be determined by the Company’s compensation committee. The number of shares available for issuance under the 2007 Plan is subject to adjustment in the event of a stock split, stock dividend or other change in capitalization. Generally, shares that are forfeited or canceled from awards under the 2007 Plan also will be available for future awards. To date, approximately 6.7 million shares have been added to the 2007 Plan in accordance with the automatic annual increase. In addition, shares subject to stock options returned to the 1999 Plan, as a result of their expiration, cancellation or termination, are automatically made available for issuance under the 2007 Plan. As of September 30, 2014 a total of 1,615,872 shares were available for grant under the 2007 Plan.
	Accounting for Stock-Based Compensation
	The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of an award.
	As there was no public market for the Company’s common stock prior to the Company’s IPO in May 2007 and, until recently, limited historical information on the volatility of its common stock since the date of the Company’s IPO, the Company has historically determined the volatility for options granted based on an analysis of the historical volatility of the Company’s stock and reported data for a peer group of companies that issued options with substantially similar terms. Beginning in 2013, the expected volatility of options granted has been determined using a weighted average of the historical volatility of the Company’s stock for a period equal to the expected life of the option. The expected life of options has been determined utilizing the “simplified” method. The risk-free interest rate is based on a zero coupon United States treasury instrument whose term is consistent with the expected life of the stock options. The Company has not paid and does not anticipate paying cash dividends on its shares of common stock; therefore, the expected dividend yield is assumed to be zero.
	A summary of the stock option activity under the Company’s stock option plan for the nine months ended September 30, 2014 is presented below:


	Year-to-Date Activity		Options			Weighted-		Weighted-		Aggregate

	During the nine months ended September 30, 2014 and 2013, the total intrinsic value of options exercised (i.e. the difference between the market price at exercise and the price paid by the employee to exercise the options) was $0.9 million and $1.2 million, respectively, and the total amount of cash received from exercise of these options was $2.2 million and $0.9 million, respectively. The total grant date fair value of stock options granted after January 1, 2006 that vested during the nine months ended September 30, 2014 and 2013 was $0.1 million and $0.5 million, respectively.
	Restricted Stock Awards
	Restricted stock awards are valued at the market price of a share of the Company’s common stock on the date of grant. A summary of the restricted stock award activity under the 2007 Plan for the nine months ended September 30, 2014 is presented below:

	Reserved Common Stock

	As of September 30, 2014, the Company has reserved 8,460,246 shares of common stock for options outstanding and restricted stock awards that have not been issued as well as those available for grant under stock option plans.

	Common Stock Repurchase Programs

	On August 5, 2014, the Company announced that, on August 4, 2014, its Board of Directors authorized a $20 million stock repurchase program (the “2014 Program”). The Company is authorized to repurchase the Company’s common stock from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased will be determined based on an evaluation of market conditions and other factors. The Company may elect to implement a Rule 10b5-1 trading plan to make such purchases, which would permit shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The 2014 Program may be suspended or discontinued at any time.

	On August 3, 2012, the Company’s Board of Directors authorized a $20 million stock repurchase program (the “2012 Program”) authorizing the Company to repurchase its common stock from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased was determined based on an evaluation of market conditions and other factors. The Company elected to implement a Rule 10b5-1 trading plan to make such purchases, which permits shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The 2012 Program was terminated immediately prior to the commencement of the tender offer on September 25, 2013 (as described below).

	During the quarter ended September 30, 2014 the Company repurchased 311,522 shares of common stock for $2.7 million pursuant to the 2014 Program. During the nine months ended September 30, 2013 the Company repurchased 2,610,279 shares of common stock for $12.4 million pursuant to the 2012 Program. Repurchased shares are recorded under the cost method and are reflected as treasury stock in the accompanying Consolidated Balance Sheets. All repurchased shares were funded with cash on hand.

	Secondary Offering

	In May 2014, the Company completed a secondary public offering of 5,750,000 shares of common stock at a price of $6.25 per share. All of the shares sold in the secondary public offering were sold by selling stockholders and the Company did not receive any proceeds from the offering. The Company incurred fees of approximately $0.5 million related to legal, accounting and other fees in connection with the secondary public offering, which are included in general and administrative expenses in the Statement of Operations and Comprehensive Income (Loss).



	Tender Offer

	On September 25, 2013, the Company commenced a tender offer to purchase up to 6.5 million shares of its common stock, representing approximately 16.79% of the shares of TechTarget’s common stock issued and outstanding at that time, at a price of $5.00 per share. On September 23, 2013, the last reported sale price of the Company’s common stock was $4.79 per share.

	The tender offer expired on October 24, 2013. In accordance with applicable SEC regulations and the terms of the tender offer, the Company exercised the right to purchase additional shares and based on the final tabulation by Computershare Trust Company, N.A., the Depositary for the tender offer, the Company accepted for purchase 7,100,565 shares of its common stock for a total cost of $35.5 million. Repurchased shares were recorded under the cost method and are reflected as treasury stock in the accompanying Consolidated Balance Sheets. The total cost of the tender offer was $35.6 million, which includes approximately $0.1 million in costs directly attributable to the purchase.

Income Taxes	'
	13. Income Taxes
	The Company’s effective income tax rate was 36.7% and 38.7% for the nine months ended September 30, 2014 and 2013, respectively. The effective income tax rate is based upon the estimated annual effective tax rate in compliance with ASC 740, Income Taxes, and other related guidance. The Company updates the estimate of its annual effective tax rate at the end of each quarterly period. The Company’s estimate takes into account estimations of annual pre-tax income, the geographic mix of pre-tax income and its interpretations of tax laws.
	The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. These amounts were not material in the nine months ended September 30, 2014.
	In March 2010, the Company received a letter from the MA DOR requesting documentation demonstrating that TSC, a wholly-owned subsidiary of the Company, has been classified by the MA DOR as a Massachusetts security corporation. Based on subsequent correspondence with the MA DOR, the Company determined that it was more likely than not that the MA DOR would require an adjustment to correct TSC’s tax filings such that it will be treated as a Massachusetts business corporation for the applicable years. The tax benefit available to a Massachusetts security corporation is a lower income tax rate. The Company recorded a tax reserve for approximately $0.4 million. The tax benefits available to a Massachusetts security corporation are comprised of (i) a different rate structure (1.32% on gross investment income vs. 9.5% on net income) and (ii) exemption from the 0.26% excise tax on net worth (see Note 9). On August 17, 2011, the Company filed Applications for Abatement with the MA DOR. On January 6, 2012, the Company filed Petitions under Formal Procedure with the Massachusetts Appellate Tax Board. A trial took place on April 29, 2014; no decision has been rendered as of the date of this report. As of September 30, 2014 the Company has recorded a liability of approximately $670 to account for the tax differential in all open years, which includes penalties and interest for the potential state income tax liability arising from the difference between the income tax rates applicable to security corporations and business corporations in Massachusetts.
	There are no income tax examinations currently in process with the exception of the matter noted above related to the MA DOR.

Principles of Consolidation	'
	Principles of Consolidation
	The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, which are comprised of KnowledgeStorm, Inc., Bitpipe, Inc., TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited, TechTarget (Beijing) Information Technology Consulting Co., Ltd., TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS and TechTarget Germany GmbH. KnowledgeStorm, Inc. and Bitpipe, Inc. feature websites that provide in-depth vendor generated content targeted to corporate IT professionals. TechTarget Securities Corporation is a Massachusetts security corporation incorporated in 2004. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. TechTarget (HK) Limited (“TTGT HK”) is a subsidiary incorporated in Hong Kong in order to facilitate the Company’s activities in the Asia-Pacific region. Additionally, through its wholly-owned subsidiaries, TTGT HK and TechTarget (Beijing) Information Technology Consulting Co., Ltd. (“TTGT Consulting”, incorporated on December 16, 2011), the Company effectively controls a variable interest entity (“VIE”), Keji Wangtuo Information Technology Co., Ltd., (“KWIT”), which was incorporated under the laws of the People’s Republic of China (“PRC”) on November 27, 2007. TechTarget (Australia) Pty Ltd. (incorporated on December 15, 2011) and TechTarget (Singapore) Pte Ltd. (incorporated on February 12, 2012) are the entities through which the Company does business in Australia and Singapore, respectively; E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH (incorporated on June 6, 2014), both wholly-owned subsidiaries of TechTarget Limited, are entities through which the Company does business in France and Germany, respectively.
	PRC laws and regulations prohibit or restrict foreign ownership of Internet-related services and advertising businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online advertising services in the PRC through KWIT. The Company entered into certain exclusive agreements with KWIT and its shareholders through TTGT HK, which obligated TTGT HK to absorb all of the risk of loss from KWIT’s activities and entitled TTGT HK to receive all of their residual returns. In addition, the Company entered into certain agreements with the authorized parties through TTGT HK, including Management and Consulting Services, Voting Proxy, Equity Pledge and Option Agreements. On December 31, 2011, TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise (“WFOE”), TTGT Consulting. The WFOE is established and existing under the laws of the PRC, and is wholly owned by TTGT HK.
	Based on these contractual arrangements, the Company consolidates the financial results of KWIT as required by Accounting Standards Codification (“ASC”) subtopic 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through the WFOE, which is the primary beneficiary of KWIT. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of KWIT assigned all of their voting rights underlying their equity interest in KWIT to the WFOE. In addition, through the other aforementioned agreements, the Company demonstrates its ability and intention to continue to exercise the ability to obtain substantially all of the profits and absorb all of the expected losses of KWIT. All significant intercompany accounts and transactions between the Company, its subsidiaries, and KWIT have been eliminated in consolidation.
Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (generally accepted accounting principles, or “GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. All adjustments, which, in the opinion of management, are considered necessary for a fair presentation of the results of operations for the periods shown, are of a normal recurring nature and have been reflected in the consolidated financial statements. The results of operations for the periods presented are not necessarily indicative of results to be expected for any other interim periods or for the full year. The information included in these consolidated financial statements should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in this report and the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
Reclassifications	'
	Reclassifications
	Beginning in the third quarter of 2014, the Company changed its presentation of transactional gains and losses arising from the impact of currency exchange rate fluctuations on transactions in foreign currency that is different from the local functional currency in order to better reflect the non-operating nature of these gains and losses, and is now including them in Other Income (Expense) on the Consolidated Statements of Operations and Comprehensive Income (Loss). Previously, these gains and losses were included in the Company’s operating expenses as General and Administrative expense. Amounts in the prior periods’ financial statements have been reclassified to conform to the current presentation. In the three months ended September 30, 2013, this resulted in an increase to Other Income and an increase in General and Administrative expense equal to $0.1 million and for the nine months ended September 30, 2013, this resulted in an increase to Other Expense and a decrease in General and Administrative expense amounting to $0.2 million. In the first half of 2014, the Company recorded gains of $0.1 million as reductions to General and Administrative expense that have now been reclassified as Other (Expense) Income for the nine months ended September 30, 2014.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including those related to revenue, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals and income taxes. Estimates of the carrying value of certain assets and liabilities are based on historical experience and on various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates.
Revenue Recognition	'
	Revenue Recognition
	The Company generates substantially all of its revenue from the sale of targeted advertising campaigns, which are delivered via its network of websites, and events. Revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, the service is performed and collectability of the resulting receivable is reasonably assured.
	The majority of the Company’s online media sales involve multiple product offerings, which are described in more detail below. Because neither vendor-specific objective evidence of fair value nor third party evidence of fair value exists for all elements in the Company’s bundled product offerings, the Company uses an estimated selling price which represents management’s best estimate of the stand-alone selling price for each deliverable in an arrangement. The Company establishes best estimates considering multiple factors including, but not limited to, class of client, size of transaction, available media inventory, pricing strategies and market conditions. The Company believes the use of the best estimate of selling price allows revenue recognition in a manner consistent with the underlying economics of the transaction. The Company uses the relative selling price method to allocate consideration at the inception of the arrangement to each deliverable in a multiple element arrangement. The relative selling price method allocates any discount in the arrangement proportionately to each deliverable on the basis of the deliverable’s best estimated selling price. Revenue is then recognized as delivery occurs.

	The Company evaluates all deliverables of an arrangement at inception and each time an item is delivered, to determine whether they represent separate units of accounting. Based on this evaluation, the arrangement consideration is measured and allocated to each of these elements.
	Online Media. Revenue for lead generation campaigns is recognized as follows:
	Lead generation campaigns all offer the Activity Intelligence™ Dashboard (the “Dashboard”). For duration-based campaigns, revenue is recognized ratably over the duration of the campaigns, which is usually less than six months. Lead generation offerings may also include an additional service, TechTarget Re-Engage (formerly called Nurture & Qualify), in which case revenue is recognized ratably over the period of the campaign as a combined unit of accounting. As part of these lead generation campaign offerings, the Company will guarantee a minimum number of qualified leads to be delivered over the course of the advertising campaign. The Company determines the content necessary to achieve performance guarantees. Scheduled end dates of advertising campaigns sometimes need to be extended, pursuant to the terms of the arrangement, to satisfy lead guarantees. The Company estimates a revenue reserve necessary to adjust revenue recognition for extended advertising campaigns. These estimates are based on the Company’s experience in managing and fulfilling these offerings. The customer has cancellation privileges which generally require advance notice by the customer and require proportional payment by the customer for the portion of the campaign period provided by the Company. Additionally, the Company offers sales incentives to certain customers, primarily in the form of volume rebates, which are classified as a reduction of revenues and are calculated based on the terms of the specific customer’s contract. The Company accrues for these sales incentives based on contractual terms and historical experience.
	The Company recognizes revenue on contracts where pricing is based on cost per lead in the period during which the leads are delivered to its customers.
	Revenue for other significant online media offerings is recognized as follows:

		•	IT Deal Alert™. This suite of products includes Qualified Sales Opportunities and Account Watch. Qualified Sales Opportunities revenue is recognized when the opportunity is delivered to the Company’s customer, and Account Watch revenue is recognized ratably over the duration of the service.

		•	Custom Content Creation. Custom content revenue is recognized when the creation is completed and delivered to the customer, with the exception of microsites which are recognized over the period during which they are live.

		•	Content Sponsorships. Content sponsorship revenue is recognized ratably over the period in which the related content asset is available on the Company’s websites.

		•	List Rentals. List rental revenue is recognized in the period in which the delivery of the list is made to the Company’s customer.

		•	Banners. Banner revenue is recognized in the period in which the banner impressions, engagements or clicks occur.

		•	Third Party Revenue Sharing Arrangements. Revenue from third party revenue sharing arrangements is recognized on a net basis in the period in which the services are performed. For certain third party agreements where the Company is the primary obligor, revenue is recognized on a gross basis in the period in which the services are performed.
	Event Sponsorships. Revenue from vendor-sponsored events, whether sponsored exclusively by a single vendor or in a multi-vendor sponsored event, is recognized upon completion of the event in the period the event occurs. The majority of the Company’s events are free to qualified attendees; however, certain events are based on a paid attendee model. The Company recognizes revenue for paid attendee events upon completion of the event.
	Amounts collected or billed prior to satisfying the above revenue recognition criteria are recorded as deferred revenue. The Company excludes from its deferred revenue and accounts receivable balances amounts for which it has billed in advance prior to the start of a campaign or the delivery of services.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Financial instruments consist of cash and cash equivalents, short and long-term investments, accounts receivable, accounts payable and contingent consideration. Due to their short-term nature and liquidity, the carrying value of these instruments with the exception of contingent consideration approximates their estimated fair values. The fair value of contingent consideration was estimated using a discounted cash flow method described in Note 5.
Long-lived Assets, Goodwill and Indefinite-lived Intangible Assets	'
	Long-lived Assets, Goodwill and Indefinite-lived Intangible Assets
	Long-lived assets consist primarily of property and equipment, capitalized software, goodwill and other intangible assets. The Company reviews long-lived assets, including property and equipment and finite intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would trigger an impairment assessment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset or an adverse action or a significant decrease in the market price. A specifically identified intangible asset must be recorded as a separate asset from goodwill if either of the following two criteria is met: (1) the intangible asset acquired arises from contractual or other legal rights; or (2) the intangible asset is separable. Accordingly, intangible assets consist of specifically identified intangible assets. Goodwill is the excess of any purchase price over the estimated fair value of net tangible and intangible assets acquired.
	Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. Separable intangible assets that are not deemed to have an indefinite life are amortized over their estimated useful lives, which range from three to ten years, using methods of amortization that are expected to reflect the estimated pattern of economic use, and are reviewed for impairment when events or changes in circumstances suggest that the assets may not be recoverable. Consistent with the Company’s determination that it has only one reporting segment, it has been determined that there is only one reporting unit and goodwill is tested for impairment at the entity level. The Company performs its annual test of impairment of goodwill as of December 31st of each year and whenever events or changes in circumstances suggest that the carrying amount may not be recoverable using the two step process required by ASC 350, Intangibles – Goodwill and Other (“ASC 350”). The first step of the impairment test is to identify potential impairment by comparing the reporting unit’s fair value with its net book value (or carrying amount), including goodwill. The fair value is estimated based on a market value approach. If the fair value of the reporting unit exceeds its carrying amount, the reporting unit’s goodwill is not considered to be impaired and the second step of the impairment test is not performed. Whenever indicators of impairment are present, the Company would perform the second step and compare the implied fair value of the reporting unit’s goodwill, as defined by ASC 350, to its carrying value to determine the amount of the impairment loss, if any. As of December 31, 2013, there were no indications of impairment based on the step one analysis, and the Company’s estimated fair value exceeded its goodwill carrying value by a significant margin.
	Based on the aforementioned evaluation, the Company believes that, as of the balance sheet date presented, none of the Company’s goodwill or other long-lived assets was impaired. The Company did not have any intangible assets with indefinite lives as of September 30, 2014 or December 31, 2013.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	The Company offsets gross trade accounts receivable with an allowance for doubtful accounts. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in their existing accounts receivable. The allowance for doubtful accounts is reviewed on a regular basis, and all past due balances are reviewed individually for collectability. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in general and administrative expense.
Property and Equipment	'
	Property and Equipment
	Property and equipment is stated at cost. Property and equipment acquired through acquisitions of businesses are initially recorded at fair value. Depreciation is calculated on the straight-line method based on the month the asset is placed in service over their estimated useful lives.
Internal-Use Software and Website Development Costs	'
	Internal-Use Software and Website Development Costs
	The Company capitalizes costs incurred during the development of its website applications and infrastructure as well as certain costs relating to internal-use software. The estimated useful life of costs capitalized is evaluated for each specific project. Capitalized internal-use software and website development costs are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized only if the carrying amount of the asset is not recoverable and exceeds its fair value. The Company capitalized internal-use software and website development costs of $0.8 million and $0.9 million for the three months ended September 30, 2014 and 2013, respectively, and $2.5 million and $2.9 million for the nine months ended September 30, 2014 and 2013, respectively.
Income Taxes	'
	Income Taxes
	The Company’s deferred tax assets and liabilities are recognized based on temporary differences between the financial reporting and income tax bases of assets and liabilities using statutory rates. A valuation allowance is established against net deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return using a “more likely than not” threshold as required by the provisions of ASC 740-10, Accounting for Uncertainty in Income Taxes.
	The Company recognizes any interest and penalties related to unrecognized tax benefits in income tax expense.
Stock-Based Compensation	'
	Stock-Based Compensation
	The Company has two stock-based compensation plans which are more fully described in Note 11. Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized in the Statement of Operations and Comprehensive Income (Loss) predominantly using the straight-line method over the vesting period of the award. The Company uses the Black-Scholes option-pricing model to determine the fair value of stock option award
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	Comprehensive income (loss) includes all changes in equity during a period, except those resulting from investments by stockholders and distributions to stockholders. The Company’s comprehensive income (loss) includes changes in the fair value of the Company’s unrealized gains (losses) on available for sale securities and foreign currency translation.
Foreign Currency	'
	Foreign Currency
	The functional currency for each of the Company’s subsidiaries is each country’s local currency. All assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date or at a historical rate. Revenues and expenses are translated at average exchange rates. Translation gains or losses are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss).
Net Income (Loss) Per Share	'
	Net Income (Loss) Per Share
	Basic earnings per share is computed based on the weighted average number of common shares and vested restricted stock awards outstanding during the period. Because the holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents, the Company does not consider these awards to be participating securities that should be included in its computation of earnings per share under the two-class method. Diluted earnings per share is computed using the weighted average number of common shares and vested restricted stock awards outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options and restricted stock awards is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense and assumed tax benefit of stock options and restricted stock awards that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options and restricted stock awards.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016 (January 1, 2017 for the Company); early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. The Company has not determined the potential effects on the consolidated financial statements.

	-1	Included in cash and cash equivalents on the accompanying consolidated balance sheets; valued at quoted market prices in active markets.
	-2	Short- and long-term investments consist of municipal bonds and government agency bonds; their fair value is calculated using an interest rate yield curve for similar instruments.
	-3	Valuation techniques and Level 3 inputs used to estimate the fair value of contingent consideration payable in connection with the LeMag acquisition in December, 2012 are described in Note 5. During the nine months ended September 30, 2014 and 2013 the contingent consideration increased by approximately $253 and $221, respectively, when it was remeasured to fair value. The remainder of the change in this balance was caused by amortization of a discount on the installment payments and foreign currency fluctuations.
