Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions. We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2016 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the six months ended June 30, 2017 . In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented. Recent Accounting Pronouncements Recently issued accounting pronouncements not yet adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other ("ASU 2017-04") : Simplifying the Test for Goodwill Impairment , which simplifies the existing two-step guidance for goodwill impairment testing by eliminating the second step resulting in a write-down to goodwill equal to the initial amount of impairment determined in step one. The ASU is to be applied prospectively for reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We are currently evaluating the impact of the provisions of ASU 2017-04 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. Note 2—Summary of Significant Accounting Policies (continued) In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ("ASU 2016-18"), to require that restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statement of cash flows. Consequently, transfers between cash and restricted cash will not be presented as a separate line item in the operating, investing or financing sections of the cash flow statement. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied retrospectively to each period presented. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact of ASU 2016-18 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") that requires financial assets measured at amortized cost be presented at the net amount expected to be collected. Credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited by the amount that the fair value is less than amortized cost. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02") in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for leases with a term greater than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods, using a modified retrospective approach and early adoption is permitted. We are currently in the process of evaluating the impact of ASU 2016-02 on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU 2016-01 requires the change in fair value of many equity investments to be recognized in net income. The standard is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-01 may result in a cumulative adjustment to retained earnings as of the beginning of the year of adoption. We are currently evaluating the impact of ASU 2016-01 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. ASU 2014-09, as amended by ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The FASB has also issued a number of additional technical corrections since the initial ASU, all of which follow the effective dates of the new revenue recognition guidance under Topic 606. The amendment allows companies to use either a full retrospective or a modified retrospective approach to adopt this ASU. We have formed a cross-functional project team and are currently assessing the impact of the adoption of this principle on our consolidated financial statements. We have performed a review of the requirements under the new revenue standard and are monitoring the activity of the FASB for applicable updates. We have not yet completed our assessment of our customer contracts or quantified the effect, if any, the new guidance will have on our consolidated financial statements, the related disclosures or our internal controls over financial reporting. However, based on the nature of our most significant revenue streams, our preliminary view is that our current revenue policies and accounting practices under which the amounts and timing of revenue are recorded is overall consistent with the core principles Note 2—Summary of Significant Accounting Policies (continued) of the new revenue standard. We anticipate adopting this ASU on January 1, 2018 using the modified retrospective approach, however, may opt for the full retrospective method depending on the final outcome of our evaluation. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08"). ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The effective date and transition requirements for the ASU is the same as the effective date and transition requirements of ASU 2014-09. We are currently in the process of evaluating the impact of ASU 2016-08 on our consolidated financial statements in conjunction with ASU 2014-09, as discussed above. In March 2016, the FASB issued ASU No. 2016-04, Liabilities – Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products ("ASU 2016-04") . ASU 2016-04 aligns recognition of the financial liabilities related to prepaid stored-value products (for example, gift cards) with Topic 606, Revenues from Contracts with Customers , for non-financial liabilities. In general, these liabilities may be extinguished proportionately in earnings as redemptions occur, or when redemption is remote if issuers are not entitled to the unredeemed stored value. ASU 2016-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. Based on our current accounting policy, we do not expect the adoption of ASU 2016-04 to have a material impact on our consolidated financial statements. Recently adopted accounting pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") that simplifies how companies account for certain aspects of share-based payments to employees, including the accounting for income taxes upon vesting or exercise of share-based payments, classification of awards as either equity or liabilities with respect to statutory tax withholding thresholds, accounting for forfeitures, as well as certain classifications on the statement of cash flows. We adopted the provisions of ASU 2016-09 effective January 1, 2017. Under ASU 2016-09, all excess tax benefits and tax deficiencies related to stock compensation are now recognized as income tax expense or benefit in the income statement instead of additional paid-in capital on the consolidated balance sheets. Since we did not have any previously unrecognized excess tax benefits, no cumulative-effect adjustment to retained earnings was required upon adoption pertaining to unrecognized excess tax benefits. Excess tax benefits are also now classified as operating activities in the consolidated statements of cash flows instead of in financing activities. The presentation of excess tax benefits on our consolidated statements of cash flows was adopted retrospectively, and accordingly, we reclassified $1.2 million of excess tax benefits under financing activities to operating activities for the six months ended June 30, 2016 on our consolidated statements of cash flows to conform to the current year presentation. Additionally, upon adoption of ASU 2016-09, we elected to account for forfeitures on stock-based compensation as they occur, rather than estimate future expected forfeitures. As a result of this accounting change, we recognized a net cumulative effect adjustment to reduce retained earnings as of January 1, 2017 for approximately $1.8 million . See Note 7 — Employee Stock-Based Compensation and Note 10 — Income Taxes for additional information on the impact of the adoption on our consolidated financial statements.

Business Combinations [Abstract]
Business Combination	Business Combination On February 28, 2017, we completed our acquisition of all the membership interests of UniRush, LLC ("UniRush"), an online direct-to-consumer GPR card and corporate payroll card provider. The fair value of the total consideration in connection with the acquisition was approximately $163.7 million , which included cash and contingent consideration in the form of an earn-out. We financed the transaction with $142.2 million in cash, of which $95 million was raised from a combination of our Revolving Facility, as discussed in Note 9 — Note Payable , and subordinated notes payable of $20 million to the selling shareholders of UniRush. The subordinated notes were repaid during the three months ended March 31, 2017. The transaction terms include an earn-out equal to the greater of (i) a specified percentage of the revenue generated by the online direct-to-consumer GPR card portfolio for the five-year period following the closing or (ii) $20 million , payable quarterly over the five years. Note 3—Business Combination (continued) The following table summarizes the preliminary fair value of consideration transferred: Consideration (In thousands) Cash, including proceeds from notes payable $ 142,154 Fair value of contingent consideration 21,500 Total consideration $ 163,654 The preliminary allocation of the purchase price is as follows: February 28, 2017 (In thousands) Assets: Cash and cash equivalents $ 656 Accounts receivable, net 5,745 Prepaid expenses and other assets 5,147 Property and equipment, net 4,233 Intangible assets 69,000 Goodwill 93,434 Total assets: 178,215 Liabilities: Accounts payable 10,861 Other liabilities 3,700 Total liabilities: 14,561 Net assets acquired $ 163,654 We have not yet completed our final allocation of the total purchase price to the assets acquired and liabilities assumed. We have made a preliminary allocation of the estimated purchase price to the assets acquired and liabilities assumed based on their estimated fair value at the date of purchase. During the measurement period, we may adjust the provisional allocation of the estimated purchase price for new information obtained about facts and circumstances that existed as of the acquisition date, that if known, would have affected the measurements of the amounts recognized at that date. Upon completion of our purchase accounting, we may make additional adjustments, and the valuations for the assets and liabilities may change. Goodwill of $93.4 million represents the excess of the purchase price over the preliminary estimate of the fair value of the underlying identifiable tangible and intangible assets acquired and liabilities assumed. The goodwill arises from the opportunity for synergies and economies of scale from the combined companies, and expanding our reach into the online direct-to-consumer and corporate payroll distribution channels. Although the goodwill will not be amortized for financial reporting purposes, it is anticipated that substantially all of the goodwill will be deductible for federal tax purposes over the statutory period of 15 years. Intangible assets consist primarily of customer relationships and trade name of $58.5 million and $5.5 million , respectively. The customer relationships will be amortized over its estimated useful life of 5 - 10 years and the trade name will be amortized over a period of 15 years . Our acquisition of UniRush was accounted for under the acquisition method of accounting, with the operating results of UniRush included in our consolidated statements of operations from March 1, 2017 to June 30, 2017 . Transaction costs incurred in connection with the acquisition were not material. Note 3—Business Combination (continued) Unaudited pro forma financial information The following unaudited pro forma summary financial results present the consolidated results of operations as if the acquisition of UniRush had occurred as of January 1, 2016, after the effect of certain adjustments, including interest expense on the debt used to fund the purchase, amortization of certain identifiable intangible assets, income and expense items not attributable to ongoing operations and related tax effects. The unaudited pro forma condensed consolidated statements of operations does not include any adjustments for any restructuring activities, operating efficiencies or cost savings. The pro forma results have been presented for comparative purposes only and are not indicative of what would have occurred had the UniRush acquisition been made as of January 1, 2016, or of any potential results which may occur in the future.

See Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2016 for further information on the criteria for classification as nonperforming. Credit Quality Indicators We closely monitor and assess the credit quality and credit risk of our loan portfolio on an ongoing basis. We continuously review and update loan risk classifications. We evaluate our loans using non-classified or classified as the primary credit quality indicator. Classified loans are those loans that have demonstrated credit weakness where we believe there is a heightened risk of principal loss, including all impaired loans. Classified loans are generally internally categorized as substandard, doubtful or loss, consistent with regulatory guidelines. The table below presents the carrying value, gross of the related allowance for loan losses, of our loans within the primary credit quality indicators related to our loan portfolio: June 30, 2017 December 31, 2016 Non-Classified Classified Non-Classified Classified (In thousands) Residential $ 3,342 $ 569 $ 3,036 $ 688 Commercial 250 — 366 — Installment 1,345 280 1,432 312 Other 3,355 — 502 — Total loans $ 8,292 $ 849 $ 5,336 $ 1,000 Impaired Loans and Troubled Debt Restructurings When, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to a borrower that we would not otherwise consider, the related loan is classified as a Troubled Debt Restructuring, or TDR. Our TDR modifications involve an extension of the maturity date at a stated interest rate lower than the current market rate for new debt with similar risk. The following table presents our impaired loans and loans that we modified as TDRs as of June 30, 2017 and December 31, 2016 : June 30, 2017 December 31, 2016 Unpaid Principal Balance Carrying Value Unpaid Principal Balance Carrying Value (In thousands) Residential $ 364 $ 297 $ 388 $ 316 Installment 198 88 220 98 Allowance for Loan Losses Activity in the allowance for loan losses consisted of the following: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands) Balance, beginning of period $ 281 $ 278 $ 277 $ 426 Provision (benefit) for loans 63 — 63 (151 ) Loans charged off (26 ) (22 ) (31 ) (22 ) Recoveries of loans previously charged off 1 10 10 13 Balance, end of period $ 319 $ 266 $ 319 $ 266

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Stock-Based Compensation	Employee Stock-Based Compensation We currently grant restricted equity awards to employees and directors under our 2010 Equity Incentive Plan. Additionally, through our 2010 Employee Stock Purchase Plan, employees are able to purchase shares of our Class A common stock at a discount through payroll deductions. We have reserved shares of our Class A common stock for issuance under these plans. Restricted Stock Units The following table summarizes restricted stock units with only service conditions granted under our 2010 Equity Incentive Plan: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands, except per share data) Restricted stock units granted 94 792 195 973 Weighted-average grant-date fair value $ 35.60 $ 23.10 $ 31.23 $ 22.59 Performance Based Restricted Stock Units During the three and six months ended June 30, 2017 , we also granted performance-based restricted stock units to certain employees that are subject to the attainment of minimum pre-established annual performance targets. The majority of these awards are tied to the achievement of an annual non-GAAP earnings per share target for the grant year. The actual number of shares subject to the award is determined at the end of the annual performance period and may range from zero to 150% percent of the target shares granted. These awards contain an additional service component after each annual performance period is concluded and the unvested balance of the shares determined at the end of the annual performance period will vest over the remaining requisite service period. Compensation expense related to these awards is recognized using the accelerated attribution method over the four -year vesting period based on the fair value of the closing market price of our Class A common stock on the date of the grant and the estimated performance that is expected to be achieved. In the case of our Chief Executive Officer, vesting of the award is based on the achievement of a total shareholder return ("TSR") relative to the S&P 600 index over the three -year performance period. Compensation expense related to these awards is recognized over the performance period based on the grant date fair value through the use of a Monte Carlo simulation and are not subsequently re-measured. The following table summarizes the performance-based restricted stock units granted under our 2010 Equity Incentive Plan: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands, except per share data) Performance based restricted stock units granted 329 — 616 237 Weighted-average grant-date fair value $ 36.35 $ — $ 36.01 $ 25.67 The total stock-based compensation expense recognized was $9.9 million and $7.4 million for the three months ended June 30, 2017 and 2016 , respectively, and $16.4 million and $13.1 million for the six months ended June 30, 2017 and 2016 , respectively. Total stock-based compensation expense includes amounts related to awards of stock options, restricted stock units (including performance-based restricted stock units) and purchases under our 2010 Employee Stock Purchase Plan. Effective January 1, 2017, as a result of the adoption of ASU 2016-09, we account for forfeitures on our stock-based compensation as they occur, rather than estimating expected forfeitures. As a result of this accounting change, we recognized a net cumulative effect adjustment to reduce retained earnings as of January 1, 2017 for approximately $1.8 million .

Debt Disclosure [Abstract]
Note Payable	Note Payable In October 2014, we entered into a $225.0 million secured credit agreement with Bank of America, N.A., as an administrative agent, Wells Fargo Bank, National Association, and the other lenders party thereto. The credit agreement provides for 1) a $75.0 million five year revolving facility (the "Revolving Facility") and 2) a five year $150.0 million term loan facility ("Term Facility" and, together with the Revolving Facility, the “Senior Credit Facility"). The credit agreement also includes an accordion feature that, subject to securing additional commitments from existing lenders or new lending institutions, will allow us to increase the aggregate amount of these facilities by up to an additional $50.0 million . As of June 30, 2017 and December 31, 2016 , our outstanding debt, net of deferred financing costs of $3.7 million and $4.3 million , respectively, consisted of the following: June 30, 2017 December 31, 2016 (In thousands) Term facility $ 90,064 $ 100,686 Revolving facility — — Total notes payable $ 90,064 $ 100,686 Quarterly principal payments of $5.6 million are payable on the loans under the Term Facility. During each of the six months ended June 30, 2017 and 2016 , we made scheduled quarterly principal payments totaling $11.3 million . The Senior Credit Facility matures on October 23, 2019 and any amounts then outstanding are due upon maturity. Note 9—Note Payable (continued) Interest At our election, loans made under the credit agreement bear interest at 1) a LIBOR rate (the “LIBOR Rate") or 2) a base rate determined by reference to the highest of (a) the Bank of America prime rate, (b) the United States federal funds rate plus 0.50% and (c) a daily rate equal to one-month LIBOR rate plus 1.0% (the “Base Rate"), plus in either case an applicable margin. The applicable margin for borrowings depends on our total leverage ratio and varies from 2.50% to 3.00% for LIBOR Rate loans and 1.50% to 2.00% for Base Rate loans. The effective interest rate on borrowings outstanding as of June 30, 2017 was 4.05% . Interest expense, excluding the amortization of debt issuance costs, related to our Senior Credit Facility was $1.1 million and $1.0 million for the three months ended June 30, 2017 and 2016 , respectively, and $2.3 million and $2.1 million for the six months ended June 30, 2017 and 2016 , respectively. Covenants and restrictions The Senior Credit Facility contains customary representations and warranties relating to us and our subsidiaries. Obligations under the Senior Credit Facility are secured by first priority liens on, and security interests in, substantially all of our company assets and each Guarantor, as defined in the agreement. The Senior Credit Facility also contains certain affirmative and negative covenants including negative covenants that limit or restrict, among other things, liens, indebtedness, investments and acquisitions, mergers and fundamental changes, asset sales, restricted payments, changes in the nature of the business, transactions with affiliates and other matters customarily restricted in such agreements. We must maintain a minimum fixed charge coverage ratio and a maximum consolidated leverage ratio at the end of each fiscal quarter, as set forth in the credit agreement. At June 30, 2017 , we were in compliance with all such covenants.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense for the six months ended June 30, 2017 and 2016 differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. The sources and tax effects of the differences are as follows: Six Months Ended June 30, 2017 2016 U.S. federal statutory tax rate 35.0 % 35.0 % State income taxes, net of federal tax benefit (0.4 ) 3.1 General business credits (2.1 ) (2.6 ) Employee stock-based compensation (5.1 ) 0.6 Other 0.8 1.0 Effective tax rate 28.2 % 37.1 % The effective tax rate for the six months ended June 30, 2017 and 2016 differs from the statutory federal income tax rate of 35% primarily due to state income taxes, net of federal tax benefit, general business credits and non-deductible employee stock-based compensation. The decrease in the effective tax rate for the six months ended June 30, 2017 as compared to the six months ended June 30, 2016 is primarily due to excess tax benefits related to stock compensation recognized as an income tax benefit instead of additional paid-in capital in accordance with ASU 2016-09 and the release of reserves for uncertain tax positions upon the completion of tax examinations and the expiration of the statute of limitations with certain taxing jurisdictions. See Note 2 — Summary of Significant Accounting Policies for additional information about our adoption of ASU 2016-09. We establish a valuation allowance when we consider it more-likely-than-not that some portion or all of the deferred tax assets will not be realized. As of June 30, 2017 and 2016 , we did not have a valuation allowance on any of our deferred tax assets as we believed it was more-likely-than-not that we would realize the benefits of our deferred tax assets. We are subject to examination by the Internal Revenue Service, or IRS, and various state tax authorities. We remain subject to examination of our federal income tax return for the years ended December 31, 2013 through 2015. We generally remain subject to examination of our various state income tax returns for a period of three to four years from the respective dates the returns were filed. Note 10—Income Taxes (continued) As of June 30, 2017 , we have net operating loss carryforwards of approximately $41.2 million and $32.3 million for federal and state tax purposes, respectively, which will be available to offset future income. If not used, these carryforwards will expire between 2017 and 2035. In addition, we have state business tax credits of approximately $7.7 million that can be carried forward indefinitely and other state business tax credits of approximately $1.1 million that will expire 2026. As of June 30, 2017 and December 31, 2016 , we had a liability of $6.8 million and $7.3 million , respectively, for unrecognized tax benefits related to various federal and state income tax matters excluding interest, penalties and related tax benefits. The reconciliation of the beginning unrecognized tax benefits balance to the ending balance is as follows: Six Months Ended June 30, 2017 2016 (In thousands) Beginning balance $ 7,314 $ 7,371 Increases related to positions taken during prior years 321 — Increases related to positions taken during the current year 1,039 889 Decreases related to positions settled with tax authorities (1,189 ) — Decreases as a result of a lapse of applicable statute of limitations $ (636 ) $ — Ending balance $ 6,849 $ 8,260 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate $ 6,849 $ 8,260 As of June 30, 2017 and 2016 , we recognized accrued interest and penalties related to unrecognized tax benefits of approximately $0.5 million and $0.9 million , respectively.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders' Equity Stock Repurchase Program In June 2015, our Board of Directors authorized, subject to regulatory approval, a repurchase of shares of our Class A Common Stock in an amount up to $150 million under a stock repurchase program with no expiration date. As of March 31, 2017, we have repurchased all $150 million of Class A common stock under the repurchase program, subject to final settlement of our open accelerated share repurchase discussed below. On May 25, 2017, our Board of Directors authorized, subject to regulatory approval, expansion of our stock repurchase program by an additional $150 million . We expect to seek regulatory approval for the proposed expansion of our stock repurchase program during the second half of 2017. Accelerated Share Repurchases We have entered into accelerated share repurchase arrangements (“ASRs”) with a financial institution from time to time under our stock repurchase program. The following table summarizes our ASR activity since inception of the repurchase program: Purchase Period End Date Number of Shares (In thousands) Average repurchase price per share ASR Amount (In thousands) March 2017 ASR September 2017 1,326 (1) (1) $ 50,000 April 2016 ASR October 2016 2,219 $ 22.54 $ 50,000 September 2015 ASR January 2016 2,342 $ 17.08 $ 40,000 (1 ) "Number of Shares" represents shares delivered in the beginning of the purchase period and does not represent the final number of shares to be delivered under the ASR. The total number of shares ultimately delivered, and therefore the average repurchase price paid per share, will be determined at the end of the applicable purchase period based on the volume-weighted average price of our Class A common stock during that period. We expect the March 2017 ASR purchase period will end by September 2017. In exchange for an up-front payment in March 2017, the financial institution delivered 1.3 million shares of our Class A common stock. Upon settlement, we will either receive additional shares from the financial institution or we may be required to deliver additional shares or cash to the financial institution, at our election. The final number of shares received upon settlement for the ASR is determined based on the volume-weighted average price of our common stock over the term of the agreement less an agreed upon discount and subject to adjustments pursuant to the terms and conditions of the ASR. The shares received are retired in the periods they are delivered, but remain authorized for registration and issuance in the future. The up-front payments are accounted for as a reduction to shareholders’ equity on our consolidated balance sheets in the periods the payments are made. The ASRs are accounted for in two separate transactions: 1) a treasury stock repurchase for the initial shares received and 2) a forward stock purchase contract indexed to our own stock for the unsettled portion of the ASR. The par value of the shares received are recorded as a reduction to common stock with the remainder recorded as a reduction to additional paid-in capital and retained earnings. The ASRs meet all of the applicable criteria for equity classification, and therefore are not accounted for as derivative instruments. The initial repurchase of shares result in an immediate reduction of the outstanding shares used to calculate the weighted-average common shares outstanding for basic and diluted earnings per share. Other In connection with our stock repurchase program, we entered into a repurchase plan in December 2015 under Rule 10b5-1 of the Exchange Act for $ 10 million . The timing, nature and amount of purchases depended on a variety of factors, including market conditions and the volume limit defined by Rule 10b-18. We completed all repurchases under this plan during the first quarter of 2016 and total repurchases amounted to approximately 0.6 million shares at an average price of $ 16.15 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Under applicable accounting guidance, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We determine the fair values of our financial instruments based on the fair value hierarchy established under applicable accounting guidance which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs used to measure fair value. For more information regarding the fair value hierarchy and how we measure fair value, see Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2016 . Note 13—Fair Value Measurements (continued) As of June 30, 2017 and December 31, 2016 , our assets and liabilities carried at fair value on a recurring basis were as follows: Level 1 Level 2 Level 3 Total Fair Value June 30, 2017 (In thousands) Assets Corporate bonds $ — $ 10,809 $ — $ 10,809 Commercial paper — 2,944 — 2,944 U.S. Treasury notes — 25,783 — 25,783 Mortgage-backed securities — 139,531 — 139,531 Municipal bonds — 1,226 — 1,226 Asset-backed securities — 23,403 — 23,403 Total assets $ — $ 203,696 $ — $ 203,696 Liabilities Contingent consideration $ — $ — $ 21,911 $ 21,911 December 31, 2016 Assets Corporate bonds $ — $ 21,535 $ — $ 21,535 Commercial paper — 12,430 — 12,430 U.S. Treasury notes — 21,563 — 21,563 Agency securities — 4,001 — 4,001 Mortgage-backed securities — 117,491 — 117,491 Municipal bonds — 1,430 — 1,430 Asset-backed securities — 29,976 — 29,976 Total assets $ — $ 208,426 $ — $ 208,426 Liabilities Contingent consideration $ — $ — $ 8,634 $ 8,634 We based the fair value of our fixed income securities held as of June 30, 2017 and December 31, 2016 on quoted prices in active markets for similar assets. We had no transfers between Level 1, Level 2 or Level 3 assets or liabilities during the three and six months ended June 30, 2017 or 2016 . The following table presents changes in our contingent consideration payable for the three and six months ended June 30, 2017 and 2016 , which is categorized in Level 3 of the fair value hierarchy: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (In thousands) Balance, beginning of period $ 26,442 $ 13,700 $ 8,634 $ 13,889 Issuance — — 18,000 — Payments of contingent consideration (531 ) (178 ) (723 ) (367 ) Purchase accounting adjustment 3,500 — 3,500 — Change in fair value of contingent consideration (7,500 ) (5,500 ) (7,500 ) (5,500 ) Balance, end of period $ 21,911 $ 8,022 $ 21,911 $ 8,022

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The following describes the valuation technique for determining the fair value of financial instruments, whether or not such instruments are carried at fair value on our consolidated balance sheets. Short-term Financial Instruments Our short-term financial instruments consist principally of unrestricted and restricted cash and cash equivalents, settlement assets and obligations, and obligations to customers . These financial instruments are short-term in nature, and, accordingly, we believe their carrying amounts approximate their fair values. Under the fair value hierarchy, these instruments are classified as Level 1. Investment Securities The fair values of investment securities have been derived using methodologies referenced in Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2016 . Under the fair value hierarchy, our investment securities are classified as Level 2. Loans We determined the fair values of loans by discounting both principal and interest cash flows expected to be collected using a discount rate commensurate with the risk that we believe a market participant would consider in determining fair value. Under the fair value hierarchy, our loans are classified as Level 3. Deposits The fair value of demand and interest checking deposits and savings deposits is the amount payable on demand at the reporting date. We determined the fair value of time deposits by discounting expected future cash flows using market-derived rates based on our market yields on certificates of deposit, by maturity, at the measurement date. Under the fair value hierarchy, our deposits are classified as Level 2. Contingent Consideration The fair value of contingent consideration obligations, such as the earn-outs associated with our acquisitions of TPG and UniRush, are estimated through valuation models designed to estimate the probability of such contingent payments based on various assumptions. Estimated payments are discounted using present value techniques to arrive at an estimated fair value. Our contingent consideration payable is classified as Level 3 because we use unobservable inputs to estimate fair value, including the probability of achieving certain earnings thresholds and appropriate discount rates. Changes in fair value of contingent consideration are recorded through operating expenses. Note Payable The fair value of our note payable is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our note payable approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. The fair value of the note payable is classified as a Level 2 liability in the fair value hierarchy. Fair Value of Financial Instruments The carrying values and fair values of certain financial instruments that were not carried at fair value, excluding short-term financial instruments for which the carrying value approximates fair value, at June 30, 2017 and December 31, 2016 are presented in the table below.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and Claims In the ordinary course of business, we are a party to various legal proceedings, including, from time to time, actions which are asserted to be maintainable as class action suits. We review these actions on an ongoing basis to determine whether it is probable and estimable that a loss has occurred and use that information when making accrual and disclosure decisions. We have provided reserves where necessary for all claims and, based on current knowledge and in part upon the advice of legal counsel, all matters are believed to be adequately covered by insurance, or, if not covered, we do not expect the outcome in any legal proceedings, individually or collectively, to have a material adverse impact on our financial condition or results of operations. During the three months ended June 30, 2016, we continued our planned conversion of customer files from our legacy third-party card processor to our new third-party card processor. As part of the conversion process, a small percentage of our active cardholders experienced limited disruptions in service. As a result of this limited disruption in service, two putative class action complaints were filed during the second quarter of 2016. Any settlement amount paid to resolve the consolidated class actions will be borne equally between us and the third-party card processor. We have recorded an estimated accrual of approximately $2.3 million , which represents our portion of the estimated total settlement amount, all of which our insurance carrier has agreed to reimburse us for. This amount is recorded in other accrued liabilities and accounts receivable on our consolidated balance sheet as of June 30, 2017 . During the three months ended June 30, 2017 , we accrued a $3.5 million expense in connection with the settlement of a lawsuit. This amount is less than amounts we expected to incur to litigate the matter. We recorded this settlement within other general and administrative expenses on our consolidated statement of operations. Other Matters We monitor the laws of all 50 states to identify state laws or regulations that apply (or may apply) to our products and services. We have obtained money transmitter licenses (or similar such licenses) where applicable, based on advice of counsel or when we have been requested to do so. If we were found to be in violation of any laws and regulations governing banking, money transmitters, electronic fund transfers, or money laundering in the United States or abroad, we could be subject to penalties or could be forced to change our business practices. From time to time we enter into contracts containing provisions that contingently require us to indemnify various parties against claims from third parties. These contracts primarily relate to: (i) contracts with our card issuing banks, under which we are responsible to them for any unrecovered overdrafts on cardholders’ accounts; (ii) certain real estate leases, under which we may be required to indemnify property owners for environmental and other liabilities, and other claims arising from our use of the premises; (iii) certain agreements with our officers, directors, and employees, under which we may be required to indemnify these persons for liabilities arising out of their relationship with us; and (iv) contracts under which we may be required to indemnify our retail distributors, suppliers, vendors and other parties with whom we have contracts against claims arising from certain of our actions, omissions, violations of law and/or infringement of patents, trademarks, copyrights and/or other intellectual property rights. Generally, a maximum obligation under these contracts is not explicitly stated. Because the obligated amounts associated with these types of agreements are not explicitly stated, the overall maximum amount of the obligation cannot be reasonably estimated. With the exception of overdrafts on cardholders’ accounts, historically, we have not been required to make payments under these and similar contingent obligations, and no liabilities have been recorded for these obligations in our consolidated balance sheets. For additional information regarding overdrafts on cardholders’ accounts, refer to Note 5 — Accounts Receivable . As of June 30, 2017 and December 31, 2016 , we had $0.5 million outstanding in standby letters of credit issued by a financial institution related to our corporate facility lease. We have provided cash collateral for these outstanding letters of credit as of June 30, 2017 and December 31, 2016 . As of June 30, 2017 and December 31, 2016 , we had restricted cash balances of $49.4 million and $12.1 million . The increase in restricted cash during the six months ended June 30, 2017 was associated with funds required to collateralize a prefunding obligation with a business partner. During the three months ended June 30, 2017 we recorded a $7.5 million reduction to our contingent consideration liability associated with an earn-out provision of a prior period acquisition. The third and final performance period under the earn-out provision ended on June 30, 2017. The reduction represents our belief that our tax refund processing business did not achieve its earn-out performance target for the twelve months ended June 30, 2017.

Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are comprised of two reportable segments: 1) Account Services and 2) Processing and Settlement Services. We identified our reportable segments based on factors such as how we manage our operations and how our chief operating decision maker views results. Our chief operating decision maker organizes and manages our business primarily on the basis of product and service offerings and uses operating income to assess profitability. The Account Services segment consists of revenues and expenses derived from our branded and private label deposit account programs. These programs include Green Dot-branded and affinity-branded GPR card accounts, private label GPR card accounts, checking accounts, payroll cards and open-loop gift cards. The Processing and Settlement Services segment consists principally of revenues and expenses derived from reload services through the Green Dot Network and our tax refund processing services. The Corporate and Other segment primarily consists of eliminations of intersegment revenues and expenses, unallocated corporate expenses, depreciation and amortization, and other costs that are not considered when management evaluates segment performance. We do not evaluate performance or allocate resources based on segment asset data, and therefore such information is not presented. The following tables present certain financial information for each of our reportable segments for the periods then ended: Three Months Ended June 30, 2017 Account Services Processing and Settlement Services Corporate and Other Total (In thousands) Operating revenues $ 175,114 $ 55,064 $ (7,630 ) $ 222,548 Operating expenses 141,536 38,578 22,243 202,357 Operating income $ 33,578 $ 16,486 $ (29,873 ) $ 20,191 Three Months Ended June 30, 2016 Account Services Processing and Settlement Services Corporate and Other Total (In thousands) Operating revenues $ 135,109 $ 45,257 $ (6,878 ) $ 173,488 Operating expenses 114,959 33,020 12,640 160,619 Operating income $ 20,150 $ 12,237 $ (19,518 ) $ 12,869 Note 17—Segment Information (continued) Six Months Ended June 30, 2017 Account Services Processing and Settlement Services Corporate and Other Total (In thousands) Operating revenues $ 342,807 $ 148,774 $ (16,032 ) $ 475,549 Operating expenses 268,213 83,681 42,088 393,982 Operating income $ 74,594 $ 65,093 $ (58,120 ) $ 81,567 Six Months Ended June 30, 2016 Account Services Processing and Settlement Services Corporate and Other Total (In thousands) Operating revenues $ 280,249 $ 136,627 $ (15,364 ) $ 401,512 Operating expenses 234,111 72,042 28,004 334,157 Operating income $ 46,138 $ 64,585 $ (43,368 ) $ 67,355

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions. We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2016 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the six months ended June 30, 2017 . In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently issued accounting pronouncements not yet adopted In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other ("ASU 2017-04") : Simplifying the Test for Goodwill Impairment , which simplifies the existing two-step guidance for goodwill impairment testing by eliminating the second step resulting in a write-down to goodwill equal to the initial amount of impairment determined in step one. The ASU is to be applied prospectively for reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We are currently evaluating the impact of the provisions of ASU 2017-04 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. Note 2—Summary of Significant Accounting Policies (continued) In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ("ASU 2016-18"), to require that restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statement of cash flows. Consequently, transfers between cash and restricted cash will not be presented as a separate line item in the operating, investing or financing sections of the cash flow statement. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The amendments should be applied retrospectively to each period presented. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact of ASU 2016-18 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") that requires financial assets measured at amortized cost be presented at the net amount expected to be collected. Credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited by the amount that the fair value is less than amortized cost. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02") in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for leases with a term greater than 12 months. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those periods, using a modified retrospective approach and early adoption is permitted. We are currently in the process of evaluating the impact of ASU 2016-02 on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"). ASU 2016-01 revises the classification and measurement of investments in certain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU 2016-01 requires the change in fair value of many equity investments to be recognized in net income. The standard is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The adoption of ASU 2016-01 may result in a cumulative adjustment to retained earnings as of the beginning of the year of adoption. We are currently evaluating the impact of ASU 2016-01 on our consolidated financial statements, however, we do not anticipate it will have a material impact upon adoption. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. ASU 2014-09, as amended by ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The FASB has also issued a number of additional technical corrections since the initial ASU, all of which follow the effective dates of the new revenue recognition guidance under Topic 606. The amendment allows companies to use either a full retrospective or a modified retrospective approach to adopt this ASU. We have formed a cross-functional project team and are currently assessing the impact of the adoption of this principle on our consolidated financial statements. We have performed a review of the requirements under the new revenue standard and are monitoring the activity of the FASB for applicable updates. We have not yet completed our assessment of our customer contracts or quantified the effect, if any, the new guidance will have on our consolidated financial statements, the related disclosures or our internal controls over financial reporting. However, based on the nature of our most significant revenue streams, our preliminary view is that our current revenue policies and accounting practices under which the amounts and timing of revenue are recorded is overall consistent with the core principles Note 2—Summary of Significant Accounting Policies (continued) of the new revenue standard. We anticipate adopting this ASU on January 1, 2018 using the modified retrospective approach, however, may opt for the full retrospective method depending on the final outcome of our evaluation. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08"). ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The effective date and transition requirements for the ASU is the same as the effective date and transition requirements of ASU 2014-09. We are currently in the process of evaluating the impact of ASU 2016-08 on our consolidated financial statements in conjunction with ASU 2014-09, as discussed above. In March 2016, the FASB issued ASU No. 2016-04, Liabilities – Extinguishment of Liabilities (Subtopic 405-20): Recognition of Breakage for Certain Prepaid Stored-Value Products ("ASU 2016-04") . ASU 2016-04 aligns recognition of the financial liabilities related to prepaid stored-value products (for example, gift cards) with Topic 606, Revenues from Contracts with Customers , for non-financial liabilities. In general, these liabilities may be extinguished proportionately in earnings as redemptions occur, or when redemption is remote if issuers are not entitled to the unredeemed stored value. ASU 2016-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. Based on our current accounting policy, we do not expect the adoption of ASU 2016-04 to have a material impact on our consolidated financial statements. Recently adopted accounting pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") that simplifies how companies account for certain aspects of share-based payments to employees, including the accounting for income taxes upon vesting or exercise of share-based payments, classification of awards as either equity or liabilities with respect to statutory tax withholding thresholds, accounting for forfeitures, as well as certain classifications on the statement of cash flows. We adopted the provisions of ASU 2016-09 effective January 1, 2017. Under ASU 2016-09, all excess tax benefits and tax deficiencies related to stock compensation are now recognized as income tax expense or benefit in the income statement instead of additional paid-in capital on the consolidated balance sheets. Since we did not have any previously unrecognized excess tax benefits, no cumulative-effect adjustment to retained earnings was required upon adoption pertaining to unrecognized excess tax benefits. Excess tax benefits are also now classified as operating activities in the consolidated statements of cash flows instead of in financing activities. The presentation of excess tax benefits on our consolidated statements of cash flows was adopted retrospectively, and accordingly, we reclassified $1.2 million of excess tax benefits under financing activities to operating activities for the six months ended June 30, 2016 on our consolidated statements of cash flows to conform to the current year presentation. Additionally, upon adoption of ASU 2016-09, we elected to account for forfeitures on stock-based compensation as they occur, rather than estimate future expected forfeitures. As a result of this accounting change, we recognized a net cumulative effect adjustment to reduce retained earnings as of January 1, 2017 for approximately $1.8 million . See Note 7 — Employee Stock-Based Compensation and Note 10 — Income Taxes for additional information on the impact of the adoption on our consolidated financial statements.
Fair Value of Financial Instruments	Short-term Financial Instruments Our short-term financial instruments consist principally of unrestricted and restricted cash and cash equivalents, settlement assets and obligations, and obligations to customers . These financial instruments are short-term in nature, and, accordingly, we believe their carrying amounts approximate their fair values. Under the fair value hierarchy, these instruments are classified as Level 1. Investment Securities The fair values of investment securities have been derived using methodologies referenced in Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2016 . Under the fair value hierarchy, our investment securities are classified as Level 2. Loans We determined the fair values of loans by discounting both principal and interest cash flows expected to be collected using a discount rate commensurate with the risk that we believe a market participant would consider in determining fair value. Under the fair value hierarchy, our loans are classified as Level 3. Deposits The fair value of demand and interest checking deposits and savings deposits is the amount payable on demand at the reporting date. We determined the fair value of time deposits by discounting expected future cash flows using market-derived rates based on our market yields on certificates of deposit, by maturity, at the measurement date. Under the fair value hierarchy, our deposits are classified as Level 2. Contingent Consideration The fair value of contingent consideration obligations, such as the earn-outs associated with our acquisitions of TPG and UniRush, are estimated through valuation models designed to estimate the probability of such contingent payments based on various assumptions. Estimated payments are discounted using present value techniques to arrive at an estimated fair value. Our contingent consideration payable is classified as Level 3 because we use unobservable inputs to estimate fair value, including the probability of achieving certain earnings thresholds and appropriate discount rates. Changes in fair value of contingent consideration are recorded through operating expenses. Note Payable The fair value of our note payable is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our note payable approximates fair value because the base interest rate charged varies with market conditions and the credit spread is commensurate with current market spreads for issuers of similar risk. The fair value of the note payable is classified as a Level 2 liability in the fair value hierarchy.
