Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of business and significant accounting policies	HealthEquity, Inc. was incorporated in the state of Delaware on September 18, 2002. The Company offers a full range of innovative solutions for managing health care accounts (Health Savings Accounts, Health Reimbursement Arrangements, and Flexible Spending Accounts) for health plans, insurance companies, and third-party administrators. In February 2006, HealthEquity, Inc. received designation by the U.S. Department of Treasury to act as a passive non-bank custodian, which allows HealthEquity, Inc. to hold custodial assets in trust for individual account holders. On July 24, 2017, HealthEquity, Inc. received designation by the U.S. Department of Treasury to act as both a passive and non-passive non-bank custodian, which allows HealthEquity, Inc. to hold custodial assets in trust for individual account holders and use discretion to direct investment of such assets held in trust. As a passive and non-passive non-bank custodian according to the Internal Revenue Code ("IRC") 1.408-2(e)(5)(ii)(B), the Company must maintain net worth (assets minus liabilities) greater than 2% of passive custodial funds held in trust at each year-end and 4% of the non-passive custodial funds held in trust at each year-end in order to take on additional custodial assets. Principles of consolidation —The condensed consolidated financial statements include the accounts of HealthEquity, Inc. and its wholly owned subsidiaries, HealthEquity Trust Company, HEQ Insurance Services, Inc., HealthEquity Advisors, LLC and HealthEquity Retirement Services, LLC (collectively referred to as, the "Company"). The Company has a 22% ownership interest in a limited partnership for investment in and the management of early stage companies in the healthcare industry, such partnership is accounted for using the equity method of accounting. The investment was approximately $206,000 as of October 31, 2017 and is included in other assets on the accompanying condensed consolidated balance sheet. The Company has a 2% ownership interest in a limited partnership that engages in the development of technology-based financial healthcare products. The Company determined there was no significant influence and therefore the investment was accounted for using the cost method of accounting. The investment was $500,000 as of October 31, 2017 and is included in other assets on the accompanying condensed consolidated balance sheet. Acquisitions of businesses are accounted for as business combinations, and accordingly, the results of operations of acquired businesses are included in the consolidated financial statements from the date of acquisition. All significant intercompany balances and transactions have been eliminated. Basis of presentation —The accompanying condensed consolidated financial statements as of October 31, 2017 and for the three and nine months ended October 31, 2017 and 2016 are unaudited and have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended January 31, 2017 . The fiscal year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Business combinations —Acquisition-related expenses incurred in conjunction with the acquisition of a business as defined by ASC 805-10 are recognized in earnings in the period in which they are incurred and are included in other expense, net on the consolidated statement of operations. During the three and nine months ended October 31, 2017 the Company incurred expense of $398,000 and $481,000 , respectively, for acquisition-related activity. Recent adopted accounting pronouncements —In March 2016, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting . This ASU requires excess tax benefits and tax deficiencies to be recognized in the statement of operations and comprehensive income, which were previously presented as a component of stockholders' equity, on a prospective basis. In addition, any excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable are to be recorded on a modified retrospective basis through a cumulative-effect adjustment to retained earnings. This ASU also requires cash flows related to excess tax benefits to be classified as an operating activity on the statement of cash flows. Finally, this ASU no longer allows tax benefits to be included in the assumed proceeds when applying the treasury stock method for computing diluted weighted-average common shares outstanding, which results in share-based awards having a more dilutive effect on net income per diluted share. The Company adopted this ASU during the three months ended April 30, 2017. As required by the standard, excess tax benefits recognized on stock-based compensation expense are reflected in our condensed consolidated statements of operations and comprehensive income as a component of the provision for income taxes rather than additional paid-in capital on a prospective basis. For the three and nine months ended October 31, 2017 , the Company recorded excess tax benefits in the amount of $2.1 million and $12.6 million , respectively, within our provision for income taxes in the condensed consolidated statements of operations and comprehensive income. In addition, any excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable are to be recorded on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption, which resulted in an increase of $8.1 million to our retained earnings as of February 1, 2017. For presentation requirements, the Company elected to prospectively apply the change in the presentation of excess tax benefits wherein excess tax benefits recognized on stock-based compensation expense are classified as operating activities on the condensed consolidated statements of cash flows for the nine months ended October 31, 2017. Prior period classification of cash flows related to excess tax benefits were not adjusted. Further, the Company elected to adopt the forfeiture provisions of this ASU, which requires the Company to account for forfeitures as they occur. The adoption of the forfeiture provisions had no material impact on the condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, which provides a more robust framework to use in determining when a set of assets and activities is a business. This ASU is effective for fiscal years beginning December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The new guidance is required to be applied on a prospective basis. The Company adopted this ASU during the three months ended July 31, 2017. The adoption had no material impact on the Company's condensed consolidated financial statements. Recent issued accounting pronouncements —On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB voted to defer the effective date to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption beginning for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the guidance in determining revenue recognition as principal versus agent. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing, which provides guidance in accounting for immaterial performance obligations and shipping and handling. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients , which provides clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for noncash consideration and completed contracts at transition. Finally, in December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606 , Revenue from Contracts with Customers, which makes minor corrections or minor improvements to the Codification that are not expected to have a significant impact. In July 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from contracts with Customers (Topic 606), Leases (Topic 840), and (Leases (Topic 842), which clarifies the transition periods related to public and private business entities. The foregoing amendments are effective for annual reporting periods beginning after December 15, 2017 and for interim reporting periods within such annual periods. The adoption of this guidance is not expected to have a material impact on the Company's revenue. The Company expects to capitalize incremental contract acquisition costs, such as sales commissions included in sales and marketing on the consolidated statement of operations, and amortize these costs over the economic life of the contractual relationship with the member. The Company's current practice is to expense sales commissions when the member is added to the Company's platform. The Company expects the adoption to have a significant impact on its consolidated financial statements. The Company will use the cumulative effect transition method and does not plan to early adopt these pronouncements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities . The amendments in this ASU revise an entity's accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. This ASU also amends certain disclosure requirements associated with the fair value of financial instruments. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted for the presentation of certain fair value changes for financial liabilities measured at fair value. The Company does not plan to early adopt and is currently evaluating the potential effect of this ASU on the consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure for both parties to a contract (i.e. lessees and lessors). ASC 842 supersedes the previous leases standard, ASC 840 leases. This ASU is effective for financial statements issued for reporting periods beginning after December 15, 2018 and requires a modified retrospective transition, and provides for certain practical expedients; early adoption is permitted. The Company does not plan to early adopt and is currently evaluating the potential effect of this ASU on the consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost be presented at the net amount expected to be collected. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company does not plan to early adopt this ASU. The Company believes the adoption of this ASU will have an immaterial impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which provides guidance on the classification of certain cash receipts and cash payments. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not plan to early adopt this ASU. The Company believes the adoption of this ASU will have an immaterial impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory , which updates the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the timing of adoption and the potential effect of this ASU on the consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which removes step two from the goodwill impairment test. As a result, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units' fair value. This ASU is effective for fiscal years beginning December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the timing of adoption; however, it does not believe this ASU will have a material impact on the Company's consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about changes to the terms or conditions of a share-based payment award. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The standard should be applied prospectively to an award modified on or after the adoption date. The Company does not expect the adoption of this ASU to have a significant impact on its condensed consolidated financial statements.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible assets and goodwill	During the three months ended July 31, 2017, the Company acquired the right to act as custodian of a portfolio of HSA Members for $6.4 million . The cost, including transaction costs, was allocated to acquired intangible member assets as of October 31, 2017 . The Company has determined the acquired intangible member assets to have a useful life of 15 years . The assets will be amortized using the straight-line amortization method, which has been determined appropriate to reflect the pattern over which the economic benefits of existing member assets are realized. To increase its product offering, during the three months ended July 31, 2017, the Company acquired the assets of BenefitGuard LLC, pursuant to a definitive asset purchase agreement, for a purchase price of $2.9 million cash. BenefitGuard LLC is a 401(k) provider that offers 3(16) plan administrator and 3(21) named fiduciary services for 401(k) employer sponsors. The Company accounted for the acquisition of assets of BenefitGuard LLC as a purchase of a business under ASC 805. The preliminary purchase price allocation resulted in customer relationships, or other intangible assets, of $2.9 million . The Company has determined the other intangible assets to have a useful life of 10 years . The asset will be amortized using the straight-line amortization method, which has been determined appropriate to reflect the pattern over which the economic benefits will be realized.

Debt Disclosure [Abstract]
Indebtedness	On September 30, 2015, the Company entered into a new credit facility (the "Credit Agreement"). The Credit Agreement provides for a secured revolving credit facility in the aggregate principal amount of $100.0 million for a term of five years . The proceeds of borrowings under the Credit Agreement may be used for general corporate purposes. No amounts have been drawn under the Credit Agreement as of October 31, 2017 . Borrowings under the Credit Agreement bear interest equal to, at the Company's option, a) an adjusted LIBOR rate or b) a customary base rate, in each case with an applicable spread to be determined based on the Company's leverage ratio as of the most recent fiscal quarter. The applicable spread for borrowing under the Credit Agreement ranges from 1.50% to 2.00% with respect to adjusted LIBOR rate borrowings and 0.50% to 1.00% with respect to customary base rate borrowings. Additionally, the Company pays a commitment fee ranging from 0.20% to 0.30% on the daily amount of the unused commitments under the Credit Agreement payable in arrears at the end of each fiscal quarter. The Company's material subsidiaries are required to guarantee the obligations of the Company under the Credit Agreement. The obligations of the Company and the guarantors under the Credit Agreement and the guarantees are secured by substantially all assets of the Company and the guarantors, subject to customary exclusions and exceptions. The Credit Agreement requires the Company to maintain a total leverage ratio of not more than 3.00 to 1.00 as of the end of each fiscal quarter and a minimum interest coverage ratio of at least 3.00 to 1.00 as of the end of each fiscal quarter.

Income Tax Disclosure [Abstract]
Income taxes	The Company follows FASB Accounting Standards Codification 740-270, Income Taxes - Interim Reporting , for the computation and presentation of its interim period tax provision. Accordingly, management estimated the effective annual tax rate and applied this rate to the year-to-date pre-tax book income to determine the interim provision for income taxes. For the three months ended October 31, 2017 , the Company recorded an income tax provision of $2.7 million and for the nine months ended October 31, 2017 an income tax provision of $4.0 million . The resulting effective income tax rate was 20.4% and 8.8% for the three and nine months ended October 31, 2017 , compared with an effective income tax rate of 31.6% and 34.6% for the three and nine months ended October 31, 2016 . For the three and nine months ended October 31, 2017 , the net impact of discrete tax items caused a 16.4 and 27.3 percentage point decrease to the effective income tax rate primarily due to the excess tax benefit on stock-based compensation expense recognized in the provision for income taxes on the condensed consolidated statements of income, pursuant to the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting . For the three and nine months ended October 31, 2016 , the net impact of discrete tax items caused a 4.6% and 1.2% decrease to the effective tax rate primarily due to the recognition of research and development tax credits. The decrease in the effective income tax rate from the same period last year is primarily due to the excess tax benefit on stock-based compensation expense recognized in the provision for income taxes on the condensed consolidated statements of income during the three and nine months ended October 31, 2017 , pursuant to the adoption of ASU 2016-09. As of October 31, 2017 and January 31, 2017 , the Company’s total gross unrecognized tax benefit was $789,000 and $674,000 , respectively. As a result of ASU No. 2013-11, certain unrecognized tax benefits have been netted against their related deferred tax assets; therefore, no unrecognized tax benefit has been recorded as of October 31, 2017 and January 31, 2017 . If recognized, $670,000 of the total gross unrecognized tax benefits would affect the Company's effective income tax rate as of October 31, 2017 . The Company files income tax returns with U.S. federal and state taxing jurisdictions and is not currently under examination with any jurisdiction. The Company remains subject to examination by federal and various state taxing jurisdictions for tax years after 2003.

Under the terms of the Incentive Plan, the Company has the ability to grant incentive and nonqualified stock options. Incentive stock options may be granted only to Company team members. Nonqualified stock options may be granted to Company team members, directors and consultants. Such options are to be exercisable at prices, as determined by the board of directors, which must be equal to no less than the fair value of the Company's common stock at the date of the grant. Stock options granted under the Incentive Plan generally expire 10 years from the date of issuance, or are forfeited 90 days after termination of employment. Shares of common stock underlying stock options that are forfeited or that expire are returned to the Incentive Plan. Stock option activity under the Company's equity incentive plans is as follows: Outstanding stock options (in thousands, except for exercise prices and term) Number of Range of Weighted- Weighted- Aggregate Outstanding as of January 31, 2017 4,716 $0.10 - 44.53 $ 18.36 7.60 $ 131,529 Granted 420 $41.28 - 51.44 $ 42.72 Exercised (1,105 ) $0.10 - 46.40 $ 11.23 Forfeited (145 ) $3.50 - 46.40 $ 32.64 Outstanding as of October 31, 2017 3,886 $0.10 - 51.44 $ 22.49 7.52 $ 107,808 Vested and expected to vest as of October 31, 2017 3,886 $ 22.49 7.52 $ 107,808 Exercisable as of October 31, 2017 1,168 $ 14.42 6.57 $ 41,797 The aggregate intrinsic value in the table above represents the difference between the estimated fair value of common stock and the exercise price of outstanding, in-the-money stock options. The key input assumptions that were utilized in the valuation of the stock options granted during the periods presented: Three months ended October 31, Nine months ended October 31, 2017 2016 2017 2016 Expected dividend yield — % — % — % — % Expected stock price volatility 37.79 % 38.15 % 37.79% - 38.01% 38.15% - 38.37% Risk-free interest rate 1.18 % 1.18% - 1.27% 1.18% - 2.07% 1.18% - 1.55% Expected life of options 4.5 years 4.50 - 6.25 years 4.50 - 6.25 years 4.50 - 6.25 years The determination of the fair value of stock options on the date of grant using an option pricing model is affected by the Company's stock price as well as assumptions regarding a number of complex and subjective variables. Expected volatility is determined using weighted average volatility of publicly traded peer companies. The Company expects that it will begin using its own historical volatility in addition to the volatility of publicly traded peer companies, as its share price history grows over time. The risk-free interest rate is determined by using published zero coupon rates on treasury notes for each grant date given the expected term on the options. The dividend yield of zero is based on the fact that the Company expects to invest cash in operations. The Company uses the "simplified" method to estimate expected term as determined under Staff Accounting Bulletin No. 110 due to the lack of sufficient option exercise history as a public company. As of October 31, 2017 , the weighted-average vesting period of non-vested awards expected to vest is approximately 1.9 years ; the amount of compensation expense the Company expects to recognize for stock options vesting in future periods is approximately $20.2 million . Restricted stock units The Company grants restricted stock units ("RSUs") to certain team members, officers, and directors under the 2014 Equity Incentive Plan. RSUs vest upon service-based criteria and performance-based criteria. Generally, service-based RSUs vest over a four -year period in equal annual installments commencing upon the first anniversary of the grant date. Performance-based RSUs ("PRSUs") vest upon the achievement of certain financial criteria and cliff vest on January 31, 2020. RSUs are valued based on the current value of the Company's closing stock price on the date of grant and stock-based compensation expense is recognized over the requisite service period. Stock-based compensation expense for PRSUs is recognized over the requisite service period based on the probable outcome of the achievement of the performance criteria. A summary of the RSU activity is as follows: (in thousands, except weight-average grant date fair value) RSUs and PRSUs Weighted-average grant date fair value Outstanding as of January 31, 2017 10 $ 26.93 Granted 435 43.78 Vested (9 ) 43.34 Forfeitures (10 ) 45.75 Outstanding as of October 31, 2017 426 $ 43.33 Stock-based compensation expense related to RSUs, including PRSUs, for the three and nine months ended October 31, 2017 was $1.4 million and $3.6 million , respectively. Total unrecorded stock-based compensation expense as of October 31, 2017 associated with RSUs was $15.0 million , which is expected to be recognized over a weighted-average period of 3.1 years .

Fair Value Disclosures [Abstract]
Fair value	Fair value measurements are made at a specific point in time, based on relevant market information. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards specify a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1—quoted prices in active markets for identical assets or liabilities; • Level 2—inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and • Level 3—unobservable inputs based on the Company’s own assumptions. Level 1 instruments are valued based on publicly available daily net asset values. Level 1 instruments consist primarily of highly liquid mutual funds. The following tables summarize the assets measured at fair value on a recurring basis and indicates the level within the fair value hierarchy reflecting the valuation techniques utilized to determine fair value: October 31, 2017 (in thousands) Level 1 Level 2 Level 3 Marketable securities: Mutual funds $ 40,711 $ — $ — January 31, 2017 (in thousands) Level 1 Level 2 Level 3 Marketable securities: Mutual funds $ 40,405 $ — $ — The carrying value of financial instruments including cash and cash equivalents and certain non-trade receivables approximate fair values as of October 31, 2017 due to the short-term nature of these instruments. The Company has classified cash and cash equivalents as Level 1 and certain non-trade receivables as Level 2 in the fair value hierarchy.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of consolidation	Principles of consolidation —The condensed consolidated financial statements include the accounts of HealthEquity, Inc. and its wholly owned subsidiaries, HealthEquity Trust Company, HEQ Insurance Services, Inc., HealthEquity Advisors, LLC and HealthEquity Retirement Services, LLC (collectively referred to as, the "Company"). The Company has a 22% ownership interest in a limited partnership for investment in and the management of early stage companies in the healthcare industry, such partnership is accounted for using the equity method of accounting. The investment was approximately $206,000 as of October 31, 2017 and is included in other assets on the accompanying condensed consolidated balance sheet. The Company has a 2% ownership interest in a limited partnership that engages in the development of technology-based financial healthcare products. The Company determined there was no significant influence and therefore the investment was accounted for using the cost method of accounting. The investment was $500,000 as of October 31, 2017 and is included in other assets on the accompanying condensed consolidated balance sheet. Acquisitions of businesses are accounted for as business combinations, and accordingly, the results of operations of acquired businesses are included in the consolidated financial statements from the date of acquisition. All significant intercompany balances and transactions have been eliminated.
Basis of presentation	Basis of presentation —The accompanying condensed consolidated financial statements as of October 31, 2017 and for the three and nine months ended October 31, 2017 and 2016 are unaudited and have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting. In the opinion of management, the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended January 31, 2017 . The fiscal year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.
Business combinations	Business combinations —Acquisition-related expenses incurred in conjunction with the acquisition of a business as defined by ASC 805-10 are recognized in earnings in the period in which they are incurred and are included in other expense, net on the consolidated statement of operations.
Recent accounting pronouncements	Recent adopted accounting pronouncements —In March 2016, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2016-09, Improvements to Employee Share-Based Payment Accounting . This ASU requires excess tax benefits and tax deficiencies to be recognized in the statement of operations and comprehensive income, which were previously presented as a component of stockholders' equity, on a prospective basis. In addition, any excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable are to be recorded on a modified retrospective basis through a cumulative-effect adjustment to retained earnings. This ASU also requires cash flows related to excess tax benefits to be classified as an operating activity on the statement of cash flows. Finally, this ASU no longer allows tax benefits to be included in the assumed proceeds when applying the treasury stock method for computing diluted weighted-average common shares outstanding, which results in share-based awards having a more dilutive effect on net income per diluted share. The Company adopted this ASU during the three months ended April 30, 2017. As required by the standard, excess tax benefits recognized on stock-based compensation expense are reflected in our condensed consolidated statements of operations and comprehensive income as a component of the provision for income taxes rather than additional paid-in capital on a prospective basis. For the three and nine months ended October 31, 2017 , the Company recorded excess tax benefits in the amount of $2.1 million and $12.6 million , respectively, within our provision for income taxes in the condensed consolidated statements of operations and comprehensive income. In addition, any excess tax benefits that were not previously recognized because the related tax deduction had not reduced current taxes payable are to be recorded on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption, which resulted in an increase of $8.1 million to our retained earnings as of February 1, 2017. For presentation requirements, the Company elected to prospectively apply the change in the presentation of excess tax benefits wherein excess tax benefits recognized on stock-based compensation expense are classified as operating activities on the condensed consolidated statements of cash flows for the nine months ended October 31, 2017. Prior period classification of cash flows related to excess tax benefits were not adjusted. Further, the Company elected to adopt the forfeiture provisions of this ASU, which requires the Company to account for forfeitures as they occur. The adoption of the forfeiture provisions had no material impact on the condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, which provides a more robust framework to use in determining when a set of assets and activities is a business. This ASU is effective for fiscal years beginning December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The new guidance is required to be applied on a prospective basis. The Company adopted this ASU during the three months ended July 31, 2017. The adoption had no material impact on the Company's condensed consolidated financial statements. Recent issued accounting pronouncements —On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB voted to defer the effective date to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption beginning for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which clarifies the guidance in determining revenue recognition as principal versus agent. In April 2016, the FASB issued ASU 2016-10, Identifying Performance Obligations and Licensing, which provides guidance in accounting for immaterial performance obligations and shipping and handling. In May 2016, the FASB issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients , which provides clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for noncash consideration and completed contracts at transition. Finally, in December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606 , Revenue from Contracts with Customers, which makes minor corrections or minor improvements to the Codification that are not expected to have a significant impact. In July 2017, the FASB issued ASU 2017-13, Revenue Recognition (Topic 605), Revenue from contracts with Customers (Topic 606), Leases (Topic 840), and (Leases (Topic 842), which clarifies the transition periods related to public and private business entities. The foregoing amendments are effective for annual reporting periods beginning after December 15, 2017 and for interim reporting periods within such annual periods. The adoption of this guidance is not expected to have a material impact on the Company's revenue. The Company expects to capitalize incremental contract acquisition costs, such as sales commissions included in sales and marketing on the consolidated statement of operations, and amortize these costs over the economic life of the contractual relationship with the member. The Company's current practice is to expense sales commissions when the member is added to the Company's platform. The Company expects the adoption to have a significant impact on its consolidated financial statements. The Company will use the cumulative effect transition method and does not plan to early adopt these pronouncements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities . The amendments in this ASU revise an entity's accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. This ASU also amends certain disclosure requirements associated with the fair value of financial instruments. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted for the presentation of certain fair value changes for financial liabilities measured at fair value. The Company does not plan to early adopt and is currently evaluating the potential effect of this ASU on the consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure for both parties to a contract (i.e. lessees and lessors). ASC 842 supersedes the previous leases standard, ASC 840 leases. This ASU is effective for financial statements issued for reporting periods beginning after December 15, 2018 and requires a modified retrospective transition, and provides for certain practical expedients; early adoption is permitted. The Company does not plan to early adopt and is currently evaluating the potential effect of this ASU on the consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires financial assets measured at amortized cost be presented at the net amount expected to be collected. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company does not plan to early adopt this ASU. The Company believes the adoption of this ASU will have an immaterial impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which provides guidance on the classification of certain cash receipts and cash payments. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company does not plan to early adopt this ASU. The Company believes the adoption of this ASU will have an immaterial impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory , which updates the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the timing of adoption and the potential effect of this ASU on the consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which removes step two from the goodwill impairment test. As a result, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting units' fair value. This ASU is effective for fiscal years beginning December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the timing of adoption; however, it does not believe this ASU will have a material impact on the Company's consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance about changes to the terms or conditions of a share-based payment award. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The standard should be applied prospectively to an award modified on or after the adoption date. The Company does not expect the adoption of this ASU to have a significant impact on its condensed consolidated financial statements.
