Accounting Policies [Abstract]
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. The Company’s critical accounting policies are those that affect its more significant judgments used in the preparation of its consolidated financial statements. A description of the Company’s critical accounting policies and estimates is contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Other than those noted in the “Accounting Guidance Adopted in 2017” section below, there were no material changes to the Company’s critical accounting policies and use of estimates during the first nine months of 2017. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited (“TTGT HK”), TechTarget (Beijing) Information Technology Consulting Co. Ltd. (“TTGT Consulting”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH. TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. 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 TTGT Consulting, 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”). TechTarget (Australia) Pty Ltd. and TechTarget (Singapore) Pte Ltd. are the entities through which the Company does business in Australia and Singapore, respectively; LeMagIT and TechTarget Germany GmbH, 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 its 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. TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise, TTGT Consulting. TTGT Consulting 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”) 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through TTGT Consulting, 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 TTGT Consulting. 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 (Generally Accepted Accounting Principles or “ ” “U.S.” Reclassifications The adoption of a recent accounting pronouncement, described in more detail in the Accounting Guidance Adopted in 2017 section below, resulted in an in immaterial adjustment to the Accumulated Deficit in the Consolidated Balance Sheet as of December 31, 2016 and in an immaterial reclassification between Operating Activities and Financing Activities in the Consolidated Statement of Cash Flows for the nine months ended September 30, 2016. There was no effect on the Consolidated Statements of Operations and Comprehensive Income. There were no reclassifications out of accumulated other comprehensive income in the periods ended September 30, 2017 or 2016. Use of Estimates The preparation of consolidated 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 consolidated 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 revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. 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. Recent Accounting Pronouncements Accounting Guidance Adopted in 2017 In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The updated guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the Consolidated Statement of Cash Flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted the provisions of the new standard on January 1, 2017. Implementing the new pronouncement resulted in the Company recognizing tax benefits and tax deficiencies related to stock compensation deductions as a component of the provision for income tax expense in the reporting period in which they occur. Additionally, the Company has applied the modified retrospective adoption approach, which resulted in the Company recording deferred tax assets of approximately $0.2 million with an offsetting entry to retained earnings. ASU 2016-09 also requires the presentation of excess tax benefit from stock options as an operating activity on the Consolidated Statement of Cash Flows instead of as a financing activity, which resulted in an immaterial reclassification in the Consolidated Statement of Cash Flows for the first nine months of 2016. Accounting Guidance Not Yet Adopted In May 2014, the FASB issued ASU 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. In July 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”). The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. As a result, this guidance is now effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017 (January 1, 2018 for the Company) and early adoption is permitted only as of annual reporting periods (including interim reporting periods within those reporting periods) beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08, , which further clarifies the implementation guidance on principal versus agent considerations contained in ASU 2014-09. In April and May 2016, the FASB issued ASU 2016-10, , and ASU 2016-12, Narrow-Scope Improvements and Practical Expedients, respectively, each of which provide further implementation guidance for ASU 2014-09. The standard may be applied retrospectively to each prior period presented, or using the modified retrospective approach, with the cumulative effect recognized as of the date of initial application. The Company anticipates adopting the standard effective January 1, 2018, using the modified retrospective approach. The Company is continuing to identify any necessary changes to its systems, processes, and internal controls to meet the standard’s reporting and disclosure requirements. Based upon evaluations to date, the Company does not anticipate any significant system, process, or internal control changes. The Company continues to progress in its evaluation of the impact of the adoption of the standard on other areas of its consolidated financial statements and disclosures, and anticipates additional required disclosures but does not anticipate a material effect on its reported revenue, its net income, or its accounting for deferred commissions balances. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Operations and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures. However, the Company anticipates that this standard will have a material impact on its financial position, primarily due to office space operating leases, for which the Company will be required to recognize lease assets and lease liabilities on its Consolidated Balance Sheets. The Company will continue to assess the potential impacts of this standard, including the impact the adoption of this guidance will have on its results of operations or cash flows, if any. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures.

Fair Value Disclosures [Abstract]
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-term 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: Fair Value Measurements at Reporting Date Using September 30, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Money market funds (1) $ 3,452 $ 3,452 $ — $ — Short-term investments(2) 8,764 — 8,764 — Long-term investments(2) 3,042 — 3,042 — Total assets $ 15,258 $ 3,452 $ 11,806 $ — Fair Value Measurements at Reporting Date Using December 31, 2016 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets: Money market funds(1) $ 4,301 $ 4,301 $ — $ — Short-term investments(2) 10,988 — 10,988 — Long-term investments(2) 7,801 — 7,801 — Total assets $ 23,090 $ 4,301 $ 18,789 $ — (1) Included in cash and cash equivalents on the accompanying Consolidated Balance Sheets; valued at quoted market prices in active markets.

Amortization expense is recorded within operating expenses as the intangible assets consist of customer-related assets which generate website traffic that the Company considers to be in support of selling and marketing activities. The Company did not write off any fully amortized intangible assets in the first nine months of 2017. The The Company expects amortization expense of intangible assets to be as follows: Years Ending December 31: Amortization Expense 2017 (October 1 – December 31) $ 43 2018 109 2019 92 2020 78 2021 94 Thereafter 126 Total $ 542 Goodwill and indefinite-lived intangible assets are not amortized but are reviewed annually for impairment or more frequently if impairment indicators arise. The Company did not have any intangible assets other than goodwill with indefinite lives as of September 30, 2017 or December 31, 2016. There were no indications of impairment as of September 30, 2017, and the Company believes that, as of the balance sheet dates presented, none of the Company’s goodwill or intangible assets was impaired.

Commitments and Contingencies and Subsequent Events	8. Commitments and Contingencies and Subsequent Events Operating Leases The Company conducts its operations in leased office facilities under various noncancelable operating lease agreements that, as amended in October 2017, expire through December 2029. On October 26, 2017, the Company and Hines Global REIT Riverside Center, LLC (“Hines”) entered into a Third Amendment (the “Third Amendment”) to the lease agreement for office space in Newton, Massachusetts, dated as of August 4, 2009, by and between the Company and MA-Riverside Project, L.L.C. (predecessor-in-interest to Hines) as amended (the “Newton Lease”). The Third Amendment extends the lease term to December 31, 2029 and preserves the Company’s option to extend the term for an additional five (5) year period subject to certain terms and conditions set forth in the Newton Lease. The Third Amendment reduces the rentable space from approximately 110,000 square feet to approximately 74,000 square feet effective January 1, 2018 and provides the Company with a one-time cash allowance of up to $3.3 million, which may be used by the Company for any purpose. Beginning on January 1, 2018, base monthly rent under the Third Amendment will be $0.3 million. The base rent will increase biennially at a rate averaging approximately 1% per year, beginning on January 1, 2020. The Company remains responsible for certain other costs under the Third Amendment, including operating expenses and taxes. The Newton Lease contains rent concessions, which the Company is receiving over the life of the Newton 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 each lease, taking into account the lease incentives and escalating lease payments. Total rent expense under the Company’s leases was approximately $3.4 million and approximately $3.3 million for the nine months ended September 30, 2017 and 2016, respectively.

Stock-Based Compensation	9. Stock-Based Compensation Stock Option and Incentive Plans In September 1999, the Company approved a stock option plan (the “1999 Plan”) that provided for the issuance of shares of common stock incentives. The 1999 Plan provided for the granting of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), and stock grants. These incentives were offered to the Company’s employees, officers, directors, consultants, and advisors. Each option is exercisable at such times and subject to such terms as determined by the Company’s Board of Directors (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 allowed the Company to grant ISOs, NSOs, stock appreciation rights, deferred stock awards, restricted stock units and other awards. Under the 2007 Plan, stock options could not be granted at less than fair market value on the date of grant, and grants generally vested over a three to four year period. Stock options granted under the 2007 Plan expire no later than ten years after the grant date. Additionally, beginning with awards made in August 2015, the Company had the option to direct a net issuance of shares for satisfaction of tax liability with respect to vesting of awards and delivery of shares. Prior to August 2015, this choice of settlement method was solely at the discretion of the award recipient. At the inception of the plan, t he Company reserved for issuance an aggregate of 2,911,667 shares of common stock under the 2007 Plan, which expired in May 2017. The 2007 Plan was subject to an automatic annual increase of shares 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 compensation committee of the Board. The number of shares available for issuance under the 2007 Plan was subject to adjustment in the event of a stock split, stock dividend or other change in capitalization. Additionally, shares that were subject to stock options returned to the 1999 Plan as a result of their expiration, cancellation, or termination were automatically made available for issuance under the 2007 Plan. Approximately 8,224,334 shares were added to the 2007 Plan in accordance with the automatic annual increase and 1999 Plan return provisions. No new awards may be granted under the 2007 Plan; however, the shares of common stock remaining in the 2007 Plan are available for issuance in connection with previously awarded grants under the 2007 Plan. In March 2017, the Board approved the 2017 Stock Option and Incentive Plan (the “2017 Plan”), which was approved by the stockholders of the Company at the 2017 Annual Meeting and became effective June 16, 2017. The 2017 Plan replaces the Company’s 2007 Plan. On that date, approximately 3,000,000 shares of Common Stock were reserved for issuance under the 2017 Plan and, generally, shares that are forfeited or canceled from awards under the 2017 Plan also will be available for future awards. Under the 2017 Plan, the Company may grant restricted stock and restricted stock units, non-qualified stock options, stock appreciation rights, performance awards, and other stock-based and cash-based awards. Shares of stock issued pursuant to restricted stock awards are restricted in that they are not transferable until they vest. Stock underlying awards of restricted stock units are not issued until the units vest. Non-qualified stock options cannot be exercised until they vest. Under the 2017 Plan, all stock options and stock appreciation rights must be granted with an exercise price that is at least equal to the fair market value of the stock on the date of grant. The 2017 Plan broadly prohibits the repricing of options and stock appreciation rights without stockholder approval and requires that no dividends or dividend equivalents be paid with respect to options or stock appreciation rights. The 2017 Plan further provides that, in the event any dividends or dividend equivalents are declared with respect to restricted stock, restricted stock units, other stock-based awards and performance awards (referred to as “full-value awards”), they would be subject to the same vesting and forfeiture provisions as the underlying award. There are a total of 635,000 shares of common stock that remain subject to outstanding stock grants under the 2017 Plan as of September 30, 2017. Accounting for Stock-Based Compensation The Company uses the Black-Scholes option pricing model to calculate the grant date fair value of an award. 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 U.S. 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. The Company applied an estimated annual forfeiture rate in determining the expense recorded in each period. A summary of the stock option activity under the Company’s plans for the nine months ended September 30, 2017 is presented below: Year-to-Date Activity Options Outstanding Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term in Years Aggregate Intrinsic Value Options outstanding at December 31, 2016 861,380 $ 9.42 Granted 20,000 10.33 Exercised (103,673 ) 5.44 $ 437 Forfeited — — Cancelled (104,087 ) 13.47 Options outstanding at September 30, 2017 673,620 $ 9.43 1.98 $ 2,310 Options exercisable at September 30, 2017 653,620 $ 9.41 1.74 $ 2,277 Options vested or expected to vest at September 30, 2017 671,652 $ 9.43 1.96 $ 2,306 During the nine months ended September 30, 2017, 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 $0.4 million. During the nine months ended September 30, 2016, the total intrinsic value of options exercised was $1.8 million. The total amount of cash received from exercise of these options was approximately $0.6 million and $4.0 million during the nine months ended September 30, 2017 and 2016, respectively. Restricted Stock Units Restricted stock units are valued at the market price of a share of the Company’s common stock on the date of the grant. A summary of the restricted stock unit activity under the Company’s plans for the nine months ended September 30, 2017 is presented below: Year-to-Date Activity Shares Weighted- Average Grant Date Fair Value Per Share Aggregate Intrinsic Value Nonvested outstanding at December 31, 2016 1,640,790 $ 8.54 Granted 618,826 9.57 Vested (759,866 ) 8.20 Forfeited (35,500 ) 9.93 Nonvested outstanding at September 30, 2017 1,464,250 $ 9.12 $ 17,483 The total grant date fair value of restricted stock units that vested during each of the nine months ended September 30, 2017 and 2016 was $6.2 million.

Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, TechTarget Securities Corporation (“TSC”), TechTarget Limited, TechTarget (HK) Limited (“TTGT HK”), TechTarget (Beijing) Information Technology Consulting Co. Ltd. (“TTGT Consulting”), TechTarget (Australia) Pty Ltd., TechTarget (Singapore) Pte Ltd., E-Magine Médias SAS (“LeMagIT”) and TechTarget Germany GmbH. TSC is a Massachusetts corporation. TechTarget Limited is a subsidiary doing business principally in the United Kingdom. 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 TTGT Consulting, 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”). TechTarget (Australia) Pty Ltd. and TechTarget (Singapore) Pte Ltd. are the entities through which the Company does business in Australia and Singapore, respectively; LeMagIT and TechTarget Germany GmbH, 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 its 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. TTGT HK assigned all of its rights and obligations to the newly formed wholly foreign-owned enterprise, TTGT Consulting. TTGT Consulting 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”) 810-10, Consolidation: Overall, because the Company holds all the variable interests of KWIT through TTGT Consulting, 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 TTGT Consulting. 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 (Generally Accepted Accounting Principles or “ ” “U.S.”
Reclassifications	Reclassifications The adoption of a recent accounting pronouncement, described in more detail in the Accounting Guidance Adopted in 2017 section below, resulted in an in immaterial adjustment to the Accumulated Deficit in the Consolidated Balance Sheet as of December 31, 2016 and in an immaterial reclassification between Operating Activities and Financing Activities in the Consolidated Statement of Cash Flows for the nine months ended September 30, 2016. There was no effect on the Consolidated Statements of Operations and Comprehensive Income. There were no reclassifications out of accumulated other comprehensive income in the periods ended September 30, 2017 or 2016.
Use of Estimates	Use of Estimates The preparation of consolidated 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 consolidated 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 revenues, long-lived assets, goodwill, the allowance for doubtful accounts, stock-based compensation, earnouts, self-insurance accruals, and income taxes. The Company reduces its accounts receivable for an allowance for doubtful accounts based on its best estimate of the amount of probable credit losses. 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Guidance Adopted in 2017 In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The updated guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the Consolidated Statement of Cash Flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted the provisions of the new standard on January 1, 2017. Implementing the new pronouncement resulted in the Company recognizing tax benefits and tax deficiencies related to stock compensation deductions as a component of the provision for income tax expense in the reporting period in which they occur. Additionally, the Company has applied the modified retrospective adoption approach, which resulted in the Company recording deferred tax assets of approximately $0.2 million with an offsetting entry to retained earnings. ASU 2016-09 also requires the presentation of excess tax benefit from stock options as an operating activity on the Consolidated Statement of Cash Flows instead of as a financing activity, which resulted in an immaterial reclassification in the Consolidated Statement of Cash Flows for the first nine months of 2016. Accounting Guidance Not Yet Adopted In May 2014, the FASB issued ASU 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. In July 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”). The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. As a result, this guidance is now effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2017 (January 1, 2018 for the Company) and early adoption is permitted only as of annual reporting periods (including interim reporting periods within those reporting periods) beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08, , which further clarifies the implementation guidance on principal versus agent considerations contained in ASU 2014-09. In April and May 2016, the FASB issued ASU 2016-10, , and ASU 2016-12, Narrow-Scope Improvements and Practical Expedients, respectively, each of which provide further implementation guidance for ASU 2014-09. The standard may be applied retrospectively to each prior period presented, or using the modified retrospective approach, with the cumulative effect recognized as of the date of initial application. The Company anticipates adopting the standard effective January 1, 2018, using the modified retrospective approach. The Company is continuing to identify any necessary changes to its systems, processes, and internal controls to meet the standard’s reporting and disclosure requirements. Based upon evaluations to date, the Company does not anticipate any significant system, process, or internal control changes. The Company continues to progress in its evaluation of the impact of the adoption of the standard on other areas of its consolidated financial statements and disclosures, and anticipates additional required disclosures but does not anticipate a material effect on its reported revenue, its net income, or its accounting for deferred commissions balances. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Operations and Comprehensive Income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures. However, the Company anticipates that this standard will have a material impact on its financial position, primarily due to office space operating leases, for which the Company will be required to recognize lease assets and lease liabilities on its Consolidated Balance Sheets. The Company will continue to assess the potential impacts of this standard, including the impact the adoption of this guidance will have on its results of operations or cash flows, if any. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment ("ASU 2017-04"). ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (step 2 of the goodwill impairment test) and instead requires only a one-step quantitative impairment test, performed by comparing the fair value of goodwill with its carrying amount. ASU 2017-04 is effective on a prospective basis effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and disclosures.
