Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	1. Organization Grubhub Inc., a Delaware corporation, and its wholly-owned subsidiaries (collectively referred to as the “Company”) provide an online and mobile platform for restaurant pick-up and delivery orders. Diners enter their delivery address or use geo-location within the mobile applications and the Company displays the menus and other relevant information for restaurants in its network. Orders may be placed directly online, via mobile applications or over the phone at no cost to the diner. The Company charges the restaurant a per order commission that is largely fee based. In certain markets, the Company also provides delivery services to restaurants on its platform that do not have their own delivery operations.

Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated interim financial statements include the accounts of Grubhub Inc. and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements include all wholly-owned subsidiaries and reflect all normal and recurring adjustments, as well as any other than normal adjustments, that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 filed with the SEC on February 28, 2017 (the “2016 Form 10-K”). All significant intercompany transactions have been eliminated in consolidation. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017. Use of Estimates The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates include revenue recognition, the allowance for doubtful accounts, website and internal-use software development costs, goodwill, depreciable lives of property and equipment, recoverability of intangible assets with definite lives and other long-lived assets, stock-based compensation and income taxes. Actual results could differ from these estimates. Changes in Accounting Principle See “ Recently Issued Accounting Pronouncements ” below for a description of accounting principle changes adopted during the six months ended June 30, 2017 related to goodwill, business combinations and stock-based compensation. Recently Issued Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (the “FASB”) In January 2017, the FASB issued Accounting Standards Update No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates Step 2 from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with its carrying amount. Under the amendment, an entity should recognize an impairment charge for the amount by which the reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. The Company elected to early adopt ASU 2017-04 beginning in the first quarter of 2017 and will apply the standard prospectively. The Company performs its annual goodwill impairment test as of September 30 th In January 2017, the FASB issued Accounting Standards Update No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 provides that when substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The Company elected to adopt ASU 2017-01 early; therefore, ASU 2017-01 is effective for transactions beginning in the first quarter of 2017 on a prospective basis. There were no transactions during the six months ended June 30, 2017 that met the definition of a business combination. The adoption of ASU 2017-01 did not have, and is not expected to have, a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows with the intent of reducing diversity in practice related to eight types of cash flows including, among others, debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and separately identifiable cash flows and application of the predominance principle. In addition, in November 2016, the FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”). ASU 2016-18 requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flow . ASU 2016-15 and ASU 2016-18 are effective for the Company beginning in first quarter of 2018 and early adoption is permitted. The amendments should be applied using a retrospective transition method to each period presented. The adoption of ASU 2016-15 and ASU 2016-18 may impact the Company’s disclosures but is otherwise not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables and held-to-maturity debt securities, which will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands disclosure requirements. ASU 2016-13 is effective for the Company beginning the first quarter of 2020 and early adoption is permitted. The guidance will be applied using the modified-retrospective approach. The adoption of ASU 2016-13 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In March 2016, the . Under ASU 2016-09, excess tax benefits and tax deficiencies are recognized as income tax expense or benefit in the income statement. ASU 2016-09 also provides entities with the option to elect an accounting policy to continue to estimate forfeitures of stock-based awards over the service period (current GAAP) or account for forfeitures when they occur . Under ASU 2016-09, previously unrecognized excess tax benefits should be recognized using a modified retrospective transition. In addition, amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement, as well as changes in the computation of weighted-average diluted shares outstanding, should be applied prospectively. ASU 2016-09 is effective for and was adopted by the Company beginning in the first quarter of 2017 : • During the three and six months ended June 30, 2017, the Company recognized excess tax benefits from stock-based compensation of $1.6 million and $3.5 million, respectively, within provision for income taxes on the condensed consolidated statements of operations and within net income on the condensed consolidated statements of cash flows. Prior to adoption, the tax effect of stock-based awards would have been recognized in additional paid-in capital on the condensed consolidated balance sheets and separately stated in financing activities in the condensed consolidated statements of cash flows (adopted prospectively). • The Company has elected to continue to estimate forfeitures of stock-based awards over the service period. • The Company recorded a cumulative-effect adjustment for previously unrecognized excess tax benefits of $2.7 million to opening retained • The excess tax benefits from the assumed proceeds available to repurchase shares were excluded in the computation of diluted earnings per share for the three and six months ended June 30, 2017 (adopted prospectively). In February 2016, the FASB issued Accounting Standards Update No. In May 2014, the FASB issued Accounting Standards Update No. , industry-specific requirements. ASU 2014-09 establishes a five-step revenue recognition process in which an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”, which defers the effective date of ASU 2014-09 by one year. In April 2016, the FASB issued Accounting Standards Update No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” (“ASU 2016-10”) , which clarifies the implementation guidance on identifying performance obligations and licensing. ASU 2016-10 reduces the cost and complexity of identifying promised goods or services and improves the guidance for determining whether promises are separately identifiable. In May 2016, the FASB issued Accounting Standards Update No. 2016-12, “ (“ASU 2016-12”), ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 will be effective for the Company in the first quarter of 2018. . Based on the Company’s initial assessment, the adoption of these ASUs is expected to have an immaterial impact on the timing of recognition of certain revenues and result in the deferral of certain incremental costs of obtaining a contract. Management does not expect the impact the adoption of these ASUs to have a material impact on the

Acquisitions	3. Acquisitions 2016 Acquisition On May 5, 2016, the Company acquired all of the issued and outstanding stock of KMLee Investments Inc. and LABite.com, Inc. (collectively, “LABite”). The purchase price for LABite was $65.8 million in cash, net of cash acquired of $2.6 million. LABite provides online and mobile food ordering and delivery services for restaurants in numerous western and southwestern cities of the United States. The acquisition has expanded the Company’s restaurant, diner and delivery networks. The results of operations of LABite have been included in the Company’s financial statements since May 5, 2016. The excess of the consideration transferred in the acquisition over the net amounts assigned to the fair value of the assets acquired was recorded as goodwill, which represents the opportunity to expand restaurant delivery services and enhance the breadth and depth of the Company’s restaurant networks. Of The assets acquired and liabilities assumed of LABite were recorded at their estimated fair values as of the closing date of May 5, 2016. The following table summarizes the final purchase price allocation acquisition-date fair values of the assets and liabilities acquired in connection with the LABite acquisition: (in thousands) Cash and cash equivalents $ 2,566 Accounts receivable 2,320 Prepaid expenses and other assets 68 Customer and vendor relationships 46,513 Property and equipment 257 Developed technology 1,731 Goodwill 40,235 Trademarks 440 Accounts payable and accrued expenses (6,303 ) Net deferred tax liability (19,412 ) Total purchase price plus cash acquired 68,415 Cash acquired (2,566 ) Net cash paid $ 65,849 Additional Information The estimated fair values of the intangible assets acquired were determined based on a combination of the income, cost, and market approaches to measure the fair value of the customer (restaurant) relationships, developed technology and trademarks. The fair value of the trademarks was measured based on the relief from royalty method. The cost approach, specifically the cost to recreate method, was used to value the developed technology. The income approach, specifically the multi-period excess earnings method, was used to value the customer (restaurant) relationships. These fair value measurements were based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value hierarchy. The Company incurred certain expenses directly and indirectly related to acquisitions which were recognized in general and administrative expenses within the condensed consolidated statements of operations for the three months ended June 30, 2017 and 2016 of $1.5 Pro Forma The following unaudited pro forma information presents a summary of the operating results of the Company for the three and six months ended June 30, 2016 as if the acquisition had occurred as of January 1 of the year prior to acquisition: Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 (in thousands, except per share data) Revenues $ 122,335 $ 241,373 Net income 10,224 21,563 Net income per share attributable to common shareholders: Basic $ 0.12 $ 0.25 Diluted $ 0.12 $ 0.25 The pro forma adjustments reflect the amortization that would have been recognized for intangible assets, elimination of transaction costs incurred and pro forma tax adjustments for three and six months ended June 30, 2016 as follows: Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 (in thousands) Depreciation and amortization $ 341 $ 1,364 Transaction costs (643 ) (1,474 ) Income tax expense 129 47 The unaudited pro forma revenues and net income are not intended to represent or be indicative of the Company’s condensed consolidated results of operations or financial condition that would have been reported had the acquisition been completed as of the beginning of the

Commitments and Contingencies	7. Commitments and Contingencies Legal In August 2011, Ameranth, Inc. (“Ameranth”) filed a patent infringement action against a number of defendants, including Grubhub Holdings Inc., in the U.S. District Court for the Southern District of California (the “Court”), Case No. 3:11-cv-1810 (“’1810 action”). In March 2012, Ameranth initiated eight additional actions for infringement of a related patent, U.S. Patent No. 8,146,077 (“’077 patent”), in the same forum, including separate actions against Grubhub Holdings Inc., Case No. 3:12-cv-739 (“’739 action”), and Seamless North America, LLC, Case No. 3:12-cv-737 (“’737 action”). In August 2012, the Court severed the claims against Grubhub Holdings Inc. and Seamless North America, LLC in the ’1810 action and consolidated them with the ’739 action and the ’737 action, respectively. Later, the Court consolidated these separate cases against Grubhub Holdings Inc. and Seamless North America, LLC, along with the approximately 40 other cases Ameranth filed in the same district, with the original ’1810 action. In their answers, Grubhub Holdings Inc. and Seamless North America, LLC denied infringement and interposed various defenses, including non-infringement, invalidity, unenforceability and inequitable conduct. No trial date has been set for this case. The consolidated district court case was stayed until January 2017, when Ameranth’s motion to lift the stay and proceed on only the ‘077 patent was granted. The Company believes this case lacks merit and that it has strong defenses to all of the infringement claims. The Company intends to defend the suit vigorously. However, the Company is unable to predict the likelihood of success of Ameranth’s infringement claims and is unable to predict the likelihood of success of its counterclaims. The Company has not recorded an accrual related to this lawsuit as of June 30, 2017, In addition to the matter described above, from time to time, the Company is involved in various other legal proceedings arising from the normal course of business activities, including labor and employment claims, some of which relate to the alleged misclassification of independent contractors. The Company does not believe any of these claims will have a material impact on its consolidated financial statements. However, Indemnification In connection with the merger of Seamless North America, LLC, Seamless Holdings Corporation and Grubhub Holdings Inc. in August 2013, the Company agreed to indemnify Aramark Holdings Corporation for negative income tax consequences associated with the October 2012 spin-off of Seamless Holdings Corporation that were the result of certain actions taken by the Company through October 29, 2014, in certain instances subject to a $15.0 million limitation. Management is not aware of any actions that would impact the indemnification obligation.

Stock-Based Compensation	9. Stock-Based Compensation The Company has granted stock options, restricted stock units and restricted stock awards under its incentive plans. Stock-based Compensation Expense The total stock-based compensation expense related to all stock-based awards was $8.2 million and $5.5 million during the three months ended June 30, 2017 and 2016, respectively, and $15.4 million and $12.4 million during the six months ended June 30, 2017 and 2016. As of June 30, 2017, $97.8 million of total unrecognized stock-based compensation expense is expected to be recognized over a weighted-average period of 3.1 years. Excess tax benefits reflect the total of the individual stock option exercise transactions and vesting of restricted stock awards and restricted stock units in which the reduction to the Company’s income tax liability is greater than the deferred tax assets that were previously recorded. During the six months ended June 30, 2017, the Company recognized excess tax benefits from stock-based compensation of $3.5 million within provision for income taxes on the condensed consolidated statements of operations and within cash flows from operating activities on the condensed consolidated statements of cash flows. six months six months Significant Accounting Policies, The Company capitalized $1.2 million and $0.4 million during the three months ended June 30, 2017 and 2016, respectively, and $2.1 million and $0.8 million during the ended June 30, 2017 and 2016, respectively, of stock-based compensation expense as website and software development costs Stock Options The Company granted 618,899 and 131,816 stock options during the six months ended June 30, 2017 and 2016, respectively. The fair value of each stock option award was estimated based on the assumptions below as of the grant date using the Black-Scholes-Merton option pricing model. Expected volatilities are based on a combination of the historical and implied volatilities of comparable publicly-traded companies and the historical volatility of the Company’s own common stock due to its limited trading history as there The Company uses historical data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The risk-free rate for the period within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions used to determine the fair value of the stock options granted during the six months ended June 30, 2017 and were as follows: Six Months Ended June 30, 2017 2016 Weighted-average fair value options granted $ 15.19 $ 10.74 Average risk-free interest rate 1.65 % 1.41 % Expected stock price volatilities 48.7 % 50.3 % Dividend yield None None Expected stock option life (years) (a) 4.00 5.78 (a) During the six months ended June 30, 2017, the expected term calculation for option awards was based on the Company’s historical exercise experience and estimated future exercise behavior. During the six months ended June 30, 2016, the expected term of option awards was estimated using a simplified method due to the limited period of time stock-based awards had been exercisable. _____________________________________________________________________________________________________________ Stock option awards as of December 31, 2016 and June 30, 2017, and changes during the ended , were as follows Options Weighted-Average Exercise Price Aggregate Intrinsic Value (thousands) Weighted-Average Exercise Term (years) Outstanding at December 31, 2016 2,992,724 $ 22.43 $ 46,608 7.68 Granted 618,899 38.49 Forfeited (96,699 ) 31.43 Exercised (389,415 ) 21.34 Outstanding at June 30, 2017 3,125,509 25.46 56,724 7.71 Vested and expected to vest at June 30, 2017 2,913,011 25.46 52,525 7.71 Exercisable at June 30, 2017 1,292,745 $ 18.41 $ 32,470 6.66 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the fair value of the common stock and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options on each date.

Earnings Per Share [Abstract]
Earnings Per Share Attributable to Common Stockholders	12. Earnings Per Share Attributable to Common Stockholders Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the period without consideration for common stock equivalents. Diluted net income per share attributable to common stockholders is computed by dividing net income by the weighted-average number of common shares outstanding during the period and potentially dilutive common stock equivalents, including stock options, restricted stock units and restricted stock awards, except in cases where the effect of the common stock equivalent would be antidilutive. Potential common stock equivalents consist of common stock issuable upon exercise of stock options and vesting of restricted stock units and restricted stock awards using the treasury stock method.

Fair Value Measurement

Fair Value Measurement	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	13. Fair Value Measurement Certain assets and liabilities are required to be recorded at fair value on a recurring basis. Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance for fair value measurements prioritizes valuation methodologies based on the reliability of the inputs in the following three-tier value hierarchy: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require. The Company applied the following methods and assumptions in estimating its fair value measurements: the Company’s commercial paper, investments in corporate and U.S. government agency bonds and certain money market funds are classified as Level 2 within the fair value hierarchy because they are valued using inputs other than quoted prices in active markets that are observable directly or indirectly. Accounts receivable and accounts payable approximate fair value due to their generally short-term maturities. The following table presents the balances of assets measured at fair value on a recurring basis as of June 30, 2017 and December 31, 2016 June 30, 2017 December 31, 2016 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 (in thousands) Money market funds $ — $ 144 $ — $ — $ 1,723 $ — Commercial paper — 136,461 — — 131,937 — Corporate bonds — 19,407 — — 16,089 — U.S. government agency bonds — — — — 5,500 — Total $ — $ 156,012 $ — $ — $ 155,249 $ — In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated interim financial statements include the accounts of Grubhub Inc. and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements include all wholly-owned subsidiaries and reflect all normal and recurring adjustments, as well as any other than normal adjustments, that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 filed with the SEC on February 28, 2017 (the “2016 Form 10-K”). All significant intercompany transactions have been eliminated in consolidation. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2017.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates include revenue recognition, the allowance for doubtful accounts, website and internal-use software development costs, goodwill, depreciable lives of property and equipment, recoverability of intangible assets with definite lives and other long-lived assets, stock-based compensation and income taxes. Actual results could differ from these estimates.
Changes in Accounting Principle	Changes in Accounting Principle See “ Recently Issued Accounting Pronouncements ” below for a description of accounting principle changes adopted during the six months ended June 30, 2017 related to goodwill, business combinations and stock-based compensation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (the “FASB”) In January 2017, the FASB issued Accounting Standards Update No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates Step 2 from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with its carrying amount. Under the amendment, an entity should recognize an impairment charge for the amount by which the reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. The Company elected to early adopt ASU 2017-04 beginning in the first quarter of 2017 and will apply the standard prospectively. The Company performs its annual goodwill impairment test as of September 30 th In January 2017, the FASB issued Accounting Standards Update No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 provides that when substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The Company elected to adopt ASU 2017-01 early; therefore, ASU 2017-01 is effective for transactions beginning in the first quarter of 2017 on a prospective basis. There were no transactions during the six months ended June 30, 2017 that met the definition of a business combination. The adoption of ASU 2017-01 did not have, and is not expected to have, a material impact on the Company’s consolidated financial position, results of operations or cash flows. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows with the intent of reducing diversity in practice related to eight types of cash flows including, among others, debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and separately identifiable cash flows and application of the predominance principle. In addition, in November 2016, the FASB issued Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash” (“ASU 2016-18”). ASU 2016-18 requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flow . ASU 2016-15 and ASU 2016-18 are effective for the Company beginning in first quarter of 2018 and early adoption is permitted. The amendments should be applied using a retrospective transition method to each period presented. The adoption of ASU 2016-15 and ASU 2016-18 may impact the Company’s disclosures but is otherwise not expected to have a material impact on its consolidated financial position, results of operations or cash flows. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 introduces a new forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables and held-to-maturity debt securities, which will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. This ASU also expands disclosure requirements. ASU 2016-13 is effective for the Company beginning the first quarter of 2020 and early adoption is permitted. The guidance will be applied using the modified-retrospective approach. The adoption of ASU 2016-13 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows. In March 2016, the . Under ASU 2016-09, excess tax benefits and tax deficiencies are recognized as income tax expense or benefit in the income statement. ASU 2016-09 also provides entities with the option to elect an accounting policy to continue to estimate forfeitures of stock-based awards over the service period (current GAAP) or account for forfeitures when they occur . Under ASU 2016-09, previously unrecognized excess tax benefits should be recognized using a modified retrospective transition. In addition, amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement, as well as changes in the computation of weighted-average diluted shares outstanding, should be applied prospectively. ASU 2016-09 is effective for and was adopted by the Company beginning in the first quarter of 2017 : • During the three and six months ended June 30, 2017, the Company recognized excess tax benefits from stock-based compensation of $1.6 million and $3.5 million, respectively, within provision for income taxes on the condensed consolidated statements of operations and within net income on the condensed consolidated statements of cash flows. Prior to adoption, the tax effect of stock-based awards would have been recognized in additional paid-in capital on the condensed consolidated balance sheets and separately stated in financing activities in the condensed consolidated statements of cash flows (adopted prospectively). • The Company has elected to continue to estimate forfeitures of stock-based awards over the service period. • The Company recorded a cumulative-effect adjustment for previously unrecognized excess tax benefits of $2.7 million to opening retained • The excess tax benefits from the assumed proceeds available to repurchase shares were excluded in the computation of diluted earnings per share for the three and six months ended June 30, 2017 (adopted prospectively). In February 2016, the FASB issued Accounting Standards Update No. In May 2014, the FASB issued Accounting Standards Update No. , industry-specific requirements. ASU 2014-09 establishes a five-step revenue recognition process in which an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”, which defers the effective date of ASU 2014-09 by one year.
