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, 2019, and in this note to the consolidated financial statements . 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 (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. 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. . 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.” 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, 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. Revenue Recognition The Company generates its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites and data analytics solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied. Accounts Receivable We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the Consolidated Statements of Income and Comprehensive Income. We assess collectability by reviewing accounts receivable on an individual basis when we identify specific customers with known disputes, overdue amounts or collectability issues and also reserve for losses on all accounts based on historical information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. At September 30, 2020, the Company’s assessment considered business and market disruptions caused by COVID-19 and estimates of expected emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict causing variability and volatility that may have a material impact on our allowance for credit losses in future periods. Other Liabilities Other liabilities consist of the long-term portions of amounts payable related to our acquisition of substantially all of the assets of Data Science Central LLC (see Notes 4 and 14) and the amounts deferred under the Coronavirus, Aid, Relief and Economic Security Act (CARES Act) which allows employers to defer the payment of the Company’s employer share of FICA payroll taxes. The amount of the employer share of FICA payroll taxes ( 6.2% of the first $ 137,700 of employee pay ) due for the period beginning on March 27, 2020, and ending December 31, 2020, can be deferred. The deferred amounts will then be payable in equal installments at December 31, 2021 and December 31, 2022. Recent Accounting Pronouncements Recently Adopted Accounting Guidance In February 2016, the FASB issued Accounting Standard Update (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 twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income 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, 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 adopted ASU 2016-02 in the first quarter of 2019 using the modified retrospective approach, and elected the package of practical expedients permitted under the transition guidance. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842. The Company elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the Consolidated Statements of Income and Comprehensive Income on a straight-line basis over the lease term. The Company recorded operating lease assets with right-of-use of $27.5 million and $2.9 million current operating lease liability and $29.2 million non-current operating lease liability as of January 1, 2019, of which $4.9 million and $0.3 million were reclassified from deferred rent and prepaid rent, respectively (see Note 9). 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 adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires implementation costs incurred by customers in cloud computing arrangements (i.e., hosting arrangements) to be capitalized under the same premises of authoritative guidance for internal-use software, and deferred over the non-cancellable term of the cloud computing arrangements plus any optional renewal periods that are reasonably certain to be exercised by the customer or for which the exercise is controlled by the service provider. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (ASU 2016-13) which amends ASC 326 “Financial Instruments—Credit Losses” which introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward -looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The Company adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Changes to Disclosure Requirements for Fair Value Measurements” (Topic 820) (ASU 2018-13), which improved the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurements. The standard removes, modifies, and adds certain disclosure requirements. The Company adopt ed the new standard effective January 1, 2020 . T he adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Accounting Guidance Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): “Simplifying the Accounting for Income Taxes” (ASU 2019-12), which simplifies the accounting for income taxes. This guidance will be effective for us in the first quarter of 2021 on a prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements.

Revenues	3. Revenues Disaggregation of Revenue The following table depicts the disaggregation of revenue according to categories consistent with how the Company evaluates its financial performance and economic risk. International revenue consists of international geo-targeted campaigns, which are campaigns targeted at an audience of members outside of North America. For the Three Months Ended September 30, For the Nine Months Ended September 30, 2020 2019 2020 2019 North America $ 21,663 $ 22,813 $ 62,518 $ 66,444 International 14,581 10,996 39,938 31,623 Total $ 36,244 $ 33,809 $ 102,456 $ 98,067 Contract Liabilities Timing may differ between the satisfaction of performance obligations and the invoicing and collections of amounts related to the Company’s contracts with customers. Liabilities are recorded for amounts that are collected in advance of the satisfaction of performance obligations. Additionally, certain customers may receive credits, which are accounted for as a material right. The Company estimates these amounts based on the expected amount of future services to be provided to customer and allocates a portion of the transaction price to these material rights. The Company recognizes these material rights as the material rights are exercised. The resulting amounts included in the contract liabilities on the accompanying Consolidated Balance Sheets were $2.5 million and $2.4 million at September 30, 2020, and December 31, 2019, respectively. Contract Liabilities Year-to-Date Activity Balance at December 31, 2019 $ 4,335 Deferral of revenue 2,177 Recognition of previously unearned revenue (1,964 ) Balance at March 31, 2020 $ 4,548 Deferral of revenue 1,822 Recognition of previously unearned revenue (1,319 ) Balance at June 30, 2020 $ 5,051 Deferral of revenue 3,095 Recognition of previously unearned revenue (1,445 ) Balance at September 30, 2020 $ 6,701 The Company elected to apply the following practical expedients: • Existence of a Significant Financing Component in a Contract . As a practical expedient, the Company has not assessed whether a contract has a significant financing component because the Company expects at contract inception that the period between payment by the customer and the transfer of promised goods or services by the Company to the customer will be one year or less. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 90 days . In addition, the Company has determined that the payment terms that the Company provides to its customers are structured primarily for reasons other than the provision of financing to the customer. • Costs to Fulfill a Contract . The Company’s revenues are primarily generated from customer contracts that are for one year or less. Costs primarily consist of incentive compensation paid based on the achievements of sales targets in a given period for related revenue streams and are recognized in the month when the revenue is earned. As a practical expedient, for amortization periods that are determined to be one year or less, the Company expenses any incremental costs of obtaining the contract with a customer when incurred. For those customer contracts greater than one year, the Company capitalizes and amortizes the expenses over the period of benefit. • Revenues Invoiced . The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.

Debt Disclosure [Abstract]
Term Loan Agreement and Line of Credit Agreement	8. Term Loan Agreement and Line of Credit Agreement On December 24, 2018, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Western Alliance Bank (the “Bank”) as the lender. The Loan Agreement provides for a $25 million term loan facility with a maturity date of December 10, 2023 (the “Term Loan”). The Term Loan is secured by a lien on substantially all of the assets of the Company, including a pledge of the stock of certain of its wholly-owned subsidiaries (limited, in the case of the stock of certain foreign subsidiaries of the Company, to no more than 65% of the capital stock of such subsidiaries). The Term Loan must be repaid quarterly, with applicable interest paid monthly, in the following manner: 1.25% of the initial aggregate borrowings are due and payable each quarter for the first two loan years, 1.88% of the initial aggregate borrowings are due and payable each quarter for the third loan year, and 2.50% of the initial aggregate borrowings are due and payable each quarter for the fourth and fifth loan years. At maturity, all outstanding amounts, including unpaid principal and accrued and unpaid interest, under the Loan Agreement will be due and payable. The Term Loan bears interest at a floating per annum rate equal to one and three-eighths percent (1.375%) above the greater of (a) the one-month U.S. LIBOR rate reported in The Wall Street Journal or (b) two percent (2.00%). On July 2, 2020, the Company entered into a Loan and Security Modification Agreement (“Modification Agreement”) with the Bank pursuant to which the Company and the Bank agreed to amend the Loan Agreement. The Modification Agreement, among other things, added or amended certain definitions in the Loan Agreement, added a financial covenant requiring the Company to maintain an Asset Coverage Ratio (as defined in the Loan Agreement) of no less than 1.0 to 1.0 tested as of the end of each quarter, and provided the Company with a new revolving line of credit facility of $20,000,000 (“Line of Credit”). The Line of Credit allows the Company to request non-formula advances in an aggregate principal amount not to exceed the Line of Credit and to use the proceeds of such advances until the facility matures on July 2, 2022 . Advances under the Line of Credit bear interest at a floating rate equal to one-quarter percent ( 0.25% ) above the Prime Rate (as published in the Money Rates section of the Western Edition of The Wall Street Journal, or such other rate of interest publicly announced from time to time by Western Alliance Bank as its Prime Rate); provided that at no time shall the interest rate on such advances be less than three and one half percent ( 3.50% ). The Modification Agreement also establishes a process by which the Company and the Bank will determine an alternative interest rate for the Company’s existing Term Loan under the Loan Agreement in the event that the Bank determines that LIBOR ceases to exist or is no longer available. In addition, the Company will be required to pay customary fees and expenses, including an annual facility fee with respect to the Line of Credit. Together, the Loan Agreement and Line of Credit are guaranteed by the Company and secured by substantially all assets of the Company and its subsidiaries. The Company had no amounts outstanding under the Line of Credit at September 30, 2020.

Lessee Disclosure [Abstract]
Leases and Contingencies	9. Leases and Contingencies On January 1, 2019, the Company adopted Topic 842 Leases using the modified retrospective approach. The Company recorded operating lease assets (right-of-use assets) of $27.5 million and operating lease liabilities of $32.1 million. There was no impact to retained earnings upon adoption of Topic 842. The Company has various non-cancelable lease agreements for certain of its offices with original lease periods expiring between 2021 and 2029. Lease terms may include options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Leases with a renewal option allow the Company to extend the lease term typically between 1 and 5 years. When determining the lease term, renewal options reasonably certain of being exercised are included in the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that the Company would exercise such option. Renewal and termination options were generally not included in the lease term for the Company's existing operating leases. Certain of the arrangements have discounted rent periods or escalating rent payment provisions. Leases with an initial term of twelve months or less are not recorded on the Consolidated Balance Sheets. The Company recognizes rent expense on a straight-line basis over the lease term. The Company’s lease agreements do not contain any material residual value guarantee or material restrictive covenants. As of September 30, 2020, operating lease assets were $24.8 million and operating lease liabilities were $28.9 million. The maturity of the Company’s operating lease liabilities as of September 30, 2020 are as follows: Minimum Lease Years Ending December 31: Payments 2020 (October 1 – December 31) $ 731 2021 4,055 2022 3,782 2023 3,696 2024 3,725 Thereafter 17,759 Total future minimum lease payments $ 33,748 Less imputed interest 4,872 Total operating lease liabilities $ 28,876 Included in the Consolidated Balance Sheet: Current operating lease liabilities $ 2,829 Non-current operating lease liabilities 26,047 Total operating lease liabilities $ 28,876 For the three and nine months ended September 30, 2020 and 2019, the total lease cost is comprised of the following amounts: Three Months Ended Nine Months Ended September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Operating lease expense $ 988 $ 964 $ 2,881 $ 2,914 Short-term lease expense 13 22 67 64 Total lease expense $ 1,001 $ 986 $ 2,948 $ 2,978 The following summarizes additional information related to operating leases: As of September 30, 2020 Weighted-average remaining lease term — operating leases 5.1 Weighted-average discount rate — operating leases 4 % If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate as the discount rate. The Company uses its best judgment when determining the incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term to the lease payments in a similar currency. 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, 2020 and December 31, 2019, 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-Based Compensation	1 0. Stock-Based Compensation Stock Option and Incentive Plans 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. 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 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. The 2007 Plan expired in May 2017. 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. There are shares of common stock that remain subject to outstanding stock grants under the 2007 Plan as of September 30, 2020. 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, 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. Grants generally vest in equal tranches over a three-year 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 based on historical averages 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, 2020 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, 2019 140,000 $ 13.14 Granted 25,000 $ 29.64 Exercised (37,500 ) $ 12.28 $ 1,036 Forfeited (5,000 ) $ 29.64 Cancelled — $ — Options outstanding at September 30, 2020 122,500 $ 16.10 6.06 $ 3,413 Options exercisable at September 30, 2020 102,500 $ 13.45 5.35 $ 3,127 Options vested or expected to vest at September 30, 2020 121,302 $ 15.96 6.02 $ 3,396 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 $1.0 million during the nine months ended 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.

Accounting Policies [Abstract]
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 (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. 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.
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.”
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, 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.
Revenue Recognition	Revenue Recognition The Company generates its revenues from the sale of targeted marketing and advertising campaigns, which it delivers via its network of websites and data analytics solutions. Revenue is recognized when performance obligations are satisfied by transferring promised goods or services to customers, as determined by applying a five-step process consisting of: a) identifying the contract, or contracts, with a customer, b) identifying the performance obligations in the contract, c) determining the transaction price, d) allocating the transaction price to the performance obligations in the contract, and e) recognizing revenue when, or as, performance obligations are satisfied.
Accounts Receivable	Accounts Receivable We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the Consolidated Statements of Income and Comprehensive Income. We assess collectability by reviewing accounts receivable on an individual basis when we identify specific customers with known disputes, overdue amounts or collectability issues and also reserve for losses on all accounts based on historical information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. In determining the amount of the allowance for credit losses, we consider historical collectability based on past due status and make judgments about the creditworthiness of customers based on ongoing credit evaluations. At September 30, 2020, the Company’s assessment considered business and market disruptions caused by COVID-19 and estimates of expected emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict causing variability and volatility that may have a material impact on our allowance for credit losses in future periods.
Other Liabilities	Other Liabilities Other liabilities consist of the long-term portions of amounts payable related to our acquisition of substantially all of the assets of Data Science Central LLC (see Notes 4 and 14) and the amounts deferred under the Coronavirus, Aid, Relief and Economic Security Act (CARES Act) which allows employers to defer the payment of the Company’s employer share of FICA payroll taxes. The amount of the employer share of FICA payroll taxes ( 6.2% of the first $ 137,700 of employee pay ) due for the period beginning on March 27, 2020, and ending December 31, 2020, can be deferred. The deferred amounts will then be payable in equal installments at December 31, 2021 and December 31, 2022.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Guidance In February 2016, the FASB issued Accounting Standard Update (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 twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income 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, 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 adopted ASU 2016-02 in the first quarter of 2019 using the modified retrospective approach, and elected the package of practical expedients permitted under the transition guidance. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842. The Company elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the Consolidated Statements of Income and Comprehensive Income on a straight-line basis over the lease term. The Company recorded operating lease assets with right-of-use of $27.5 million and $2.9 million current operating lease liability and $29.2 million non-current operating lease liability as of January 1, 2019, of which $4.9 million and $0.3 million were reclassified from deferred rent and prepaid rent, respectively (see Note 9). 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 adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which requires implementation costs incurred by customers in cloud computing arrangements (i.e., hosting arrangements) to be capitalized under the same premises of authoritative guidance for internal-use software, and deferred over the non-cancellable term of the cloud computing arrangements plus any optional renewal periods that are reasonably certain to be exercised by the customer or for which the exercise is controlled by the service provider. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The Company adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (ASU 2016-13) which amends ASC 326 “Financial Instruments—Credit Losses” which introduces a new methodology for accounting for credit losses on financial instruments. The guidance establishes a new forward -looking "expected loss model" that requires entities to estimate current expected credit losses on accounts receivable and financial instruments by using all practical and relevant information. The Company adopted the new standard effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Changes to Disclosure Requirements for Fair Value Measurements” (Topic 820) (ASU 2018-13), which improved the effectiveness of disclosure requirements for recurring and nonrecurring fair value measurements. The standard removes, modifies, and adds certain disclosure requirements. The Company adopt ed the new standard effective January 1, 2020 . T he adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Accounting Guidance Not Yet Adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): “Simplifying the Accounting for Income Taxes” (ASU 2019-12), which simplifies the accounting for income taxes. This guidance will be effective for us in the first quarter of 2021 on a prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements.
