BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business Vantiv, Inc., a Delaware corporation, is a holding company that conducts its operations through its majority-owned subsidiary, Vantiv Holding, LLC (“Vantiv Holding”). Vantiv, Inc. and Vantiv Holding are referred to collectively as the “Company,” “Vantiv,” “we,” “us” or “our,” unless the context requires otherwise. The Company provides electronic payment processing services to merchants and financial institutions throughout the United States of America and operates in two reportable segments, Merchant Services and Financial Institution Services. For more information about the Company’s segments, refer to Note 11 - Segment Information. The Company markets its services through diverse distribution channels, including national, regional and mid-market sales teams, third-party reseller clients and a telesales operation. The Company also has relationships with a broad range of referral partners that include merchant banks, independent software vendors (“ISVs”), value-added resellers (“VARs”), payment facilitators, independent sales organizations (“ISOs”) and trade associations, as well as arrangements with core processors. Basis of Presentation and Consolidation The accompanying consolidated financial statements include those of Vantiv, Inc. and all subsidiaries thereof, including its majority-owned subsidiary, Vantiv Holding, LLC. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and should be read in connection with the Company’s 2016 audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K. The accompanying consolidated financial statements are unaudited; however, in the opinion of management they include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented. Results of operations reported for interim periods are not necessarily indicative of results for the entire year due to seasonal fluctuations in the Company’s revenue as a result of consumer spending patterns. All intercompany balances and transactions have been eliminated. As of September 30, 2017 , Vantiv, Inc. and Fifth Third Bank (“Fifth Third”) owned interests in Vantiv Holding of 91.42% and 8.58% , respectively (see Note 6 - Controlling and Non-controlling Interests for changes in non-controlling interests). The Company accounts for non-controlling interests in accordance with Accounting Standards Codification (“ASC”) 810, Consolidation . Non-controlling interests primarily represent Fifth Third’s minority share of net income or loss of equity in Vantiv Holding. Net income attributable to non-controlling interests does not include expenses incurred directly by Vantiv, Inc., including income tax expense attributable to Vantiv, Inc. Non-controlling interests are presented as a component of equity in the accompanying consolidated statements of financial position. Share Repurchase Program In October 2016, our board of directors authorized a program to repurchase up to $250 million of our Class A common stock. The Company has approximately $243 million of share repurchase authority remaining as of September 30, 2017 under this authorization. Purchases under the programs may be made from time to time in the open market, in privately negotiated transactions, or otherwise. The manner, timing and amount of any purchases will be determined by management based on an evaluation of market conditions, stock price and other factors. The Company’s share repurchase program does not obligate it to acquire any specific number or amount of shares, there is no guarantee as to the exact number or amount of shares that may be repurchased, if any, and the Company may discontinue purchases at any time that it determines additional purchases are not warranted. Sponsorship In order to provide electronic payment processing services, Visa, Mastercard and other payment networks require sponsorship of non-financial institutions by a member clearing bank. The Company has an agreement with Fifth Third (the “Sponsoring Member”) to provide sponsorship services to the Company through December 31, 2024. The Company also has agreements with certain other banks that provide sponsorship into the card networks. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Revenue Recognition The Company has contractual agreements with its clients that set forth the general terms and conditions of the relationship including line item pricing, payment terms and contract duration. Revenues are recognized as earned (i.e., for transaction based fees, when the underlying transaction is processed) in conjunction with ASC 605, Revenue Recognition . ASC 605, Revenue Recognition , establishes guidance as to when revenue is realized or realizable and earned by using the following criteria: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price is fixed or determinable; and (4) collectibility is reasonably assured. The Company follows guidance provided in ASC 605-45, Principal Agent Considerations, which states that the determination of whether a company should recognize revenue based on the gross amount billed to a customer or the net amount retained is a matter of judgment that depends on the facts and circumstances of the arrangement and that certain factors should be considered in the evaluation. The Company recognizes processing revenues net of interchange fees, which are assessed to the Company’s merchant customers on all processed transactions. Interchange rates are not controlled by the Company, which effectively acts as a clearing house collecting and remitting interchange fee settlement on behalf of issuing banks, debit networks, credit card associations and its processing customers. All other revenue is reported on a gross basis, as the Company contracts directly with the end customer, assumes the risk of loss and has pricing flexibility. The Company generates revenue primarily by processing electronic payment transactions. Set forth below is a description of the Company’s revenue by segment. Merchant Services The Company’s Merchant Services segment revenue is primarily derived from processing credit and debit card transactions. Merchant Services revenue is primarily comprised of fees charged to businesses, net of interchange fees, for payment processing services, including authorization, capture, clearing, settlement and information reporting of electronic transactions. The fees charged consist of either a percentage of the dollar volume of the transaction or a fixed fee, or both, and are recognized at the time of the transaction. Merchant Services revenue also includes a number of revenue items that are incurred by the Company and are reimbursable as the costs are passed through to and paid by the Company’s clients. These items primarily consist of Visa, Mastercard and other payment network fees. In addition, for sales through referral partners in which the Company is the primary party to the contract with the merchant, the Company records the full amount of the fees collected from the merchant as revenue. Merchant Services segment revenue also includes revenue from ancillary services such as fraud management, equipment sales and terminal rent. Merchant Services revenue is recognized as services are performed. Financial Institution Services The Company’s Financial Institution Services segment revenues are primarily derived from debit, credit and automated teller machine (“ATM”) card transaction processing, ATM driving and support, and PIN debit processing services. Financial Institution Services revenue associated with processing transactions includes per transaction and account related fees, card production fees and fees generated from the Company’s Jeanie network. Financial Institution Services revenue related to card transaction processing is recognized when consumers use their client-issued cards to make purchases. Financial Institution Services also generates revenue through other services, including statement production, collections and inbound/outbound call centers for credit transactions and other services such as credit card portfolio analytics, program strategy and support, fraud and security management and chargeback and dispute services. Financial Institution Services revenue is recognized as services are performed. Financial Institution Services provides certain services to Fifth Third. Revenues related to these services are included in the accompanying statements of income as related party revenues. Expenses Set forth below is a brief description of the components of the Company’s expenses: • Network fees and other costs primarily consist of pass through expenses incurred by the Company in connection with providing processing services to its clients, including Visa and Mastercard network association fees, payment network fees, third party processing fees, telecommunication charges, postage and card production costs. • Sales and marketing expense primarily consists of salaries and benefits paid to sales personnel, sales management and other sales and marketing personnel, residual payments made to referral partners, and advertising and promotional costs. • Other operating costs primarily consist of salaries and benefits paid to operational and IT personnel, costs associated with operating the Company’s technology platform and data centers, information technology costs for processing transactions, product development costs, software fees and maintenance costs. • General and administrative expenses primarily consist of salaries and benefits paid to executive management and administrative employees, including finance, human resources, product development, legal and risk management, share-based compensation costs, equipment, occupancy and consulting costs. The nine months ended September 30, 2017 includes a charge related to a settlement agreement stemming from legacy litigation of an acquired company. • Non-operating income for the three and nine months ended September 30, 2017 consists of an unrealized gain relating to the change in the fair value of a deal contingent forward entered into in connection with the pending Worldpay Group plc (“Worldpay”) acquisition (see Note 12 - Pending Worldpay Transaction), partially offset by the change in fair value of a tax receivable agreement (“TRA”) entered into as part of the acquisition of Mercury Payment Systems, LLC (“Mercury”). Non-operating expenses for the three and nine months ended September 30, 2016 primarily relate to the change in fair value of a TRA entered into as part of the acquisition of Mercury. (see Note 8 - Fair Value Measurements). Share-Based Compensation The Company expenses employee share-based payments under ASC 718, Compensation—Stock Compensation , which requires compensation cost for the grant-date fair value of share-based payments to be recognized over the requisite service period. The Company estimates the grant date fair value of the share-based awards issued in the form of options using the Black-Scholes option pricing model. The fair value of shares issued under the Employee Stock Purchase Plan (“ESPP”), as restricted stock awards and performance awards is measured based on the market price of the Company’s stock on the grant date. In 2017, the Compensation Committee of the Company’s Board of Directors approved a resolution that stock options, restricted shares and restricted stock units shall vest or become exercisable in three equal annual installments beginning on the first anniversary of the grant date. In March 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-09, Compensation- Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The update simplifies several aspects of the accounting for share-based payment award transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Company adopted this ASU on January 1, 2017. Under previous guidance, excess tax benefits and deficiencies from share-based compensation arrangements were recorded in equity when the awards vested or settled. ASU 2016-09 requires prospective recognition of excess tax benefits and deficiencies in the income statement, resulting in the recognition of excess tax benefits of $1.9 million and $16.0 million in income tax expense, rather than in paid-in capital, for the three and nine months ended September 30, 2017 , respectively. Additionally, under ASU 2016-09, excess income tax benefits from share-based compensation arrangements are classified as cash flow from operations, rather than as cash flow from financing activities. The Company has elected to apply the cash flow classification guidance of ASU 2016-09 prospectively, resulting in an increase to operating cash flow of $16.0 million for the nine months ended September 30, 2017 , and the prior year period has not been adjusted. The presentation requirements for cash flows related to employee taxes paid for withheld shares have no impact to the periods presented in our consolidated cash flows statements since such cash flows have historically been presented as a financing activity. Prior to adopting ASU 2016-09 the Company estimated forfeitures as part of share-based compensation expense. Under ASU 2016-09, an entity can make an election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur. The Company has elected to account for forfeitures as they occur. The cumulative-effect of this change in election resulted in an increase to additional paid-in capital of $1.3 million , an increase to deferred tax assets of $0.5 million , and a decrease to retained earnings of $0.8 million at the beginning of 2017. ASU 2016-09 requires excess tax benefits and deficiencies to be prospectively excluded from assumed future proceeds in the calculation of diluted shares, resulting in an increase in diluted weighted average shares outstanding of approximately 364,000 shares and 412,000 shares for the three and nine months ended September 30, 2017 , respectively. For the nine months ended September 30, 2017 and 2016 total share-based compensation expense was $35.1 million and $25.9 million , respectively. Earnings Per Share Basic earnings per share is computed by dividing net income attributable to Vantiv, Inc. by the weighted average shares outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to Vantiv, Inc., adjusted as necessary for the impact of potentially dilutive securities, by the weighted-average shares outstanding during the period and the impact of securities that would have a dilutive effect on earnings per share. See Note 9 - Net Income Per Share for further discussion. Dividend Restrictions The Company does not intend to pay cash dividends on its Class A common stock in the foreseeable future. Vantiv, Inc. is a holding company that does not conduct any business operations of its own. As a result, Vantiv, Inc.’s ability to pay cash dividends on its common stock, if any, is dependent upon cash dividends and distributions and other transfers from Vantiv Holding. The amounts available to Vantiv, Inc. to pay cash dividends are subject to the covenants and distribution restrictions in its subsidiaries’ loan agreements. As a result of the restrictions on distributions from Vantiv Holding and its subsidiaries, essentially all of the Company’s consolidated net assets are held at the subsidiary level and are restricted as of September 30, 2017 . Income Taxes Vantiv, Inc. is taxed as a C corporation for U.S. income tax purposes and is therefore subject to both federal and state taxation at a corporate level. Income taxes are computed in accordance with ASC 740, Income Taxes , and reflect the net tax effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and the corresponding income tax amounts. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, such deferred tax assets will be adjusted through the Company’s provision for income taxes in the period in which this determination is made. As of September 30, 2017 and December 31, 2016 , the Company had recorded no valuation allowances against deferred tax assets. The Company’s consolidated interim effective tax rate is based upon expected annual income from operations, statutory tax rates and tax laws in the various jurisdictions in which the Company operates. Significant or unusual items, including adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. The Company’s effective tax rates were 26.7% and 31.8% respectively, for the nine months ended September 30, 2017 and 2016 . The effective tax rate for each period reflects the impact of the Company’s non-controlling interests not being taxed at the statutory corporate tax rates. The effective tax rate for the nine months ended September 30, 2017 includes a $16.0 million credit to income tax expense relating to excess tax benefits as a result of the Company’s adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting . Cash and Cash Equivalents Cash on hand and investments with original maturities of three months or less (that are readily convertible to cash) are considered to be cash equivalents. Accounts Receivable—net Accounts receivable primarily represent processing revenues earned but not collected. For a majority of its customers, the Company has the authority to debit the client’s bank accounts through the Federal Reserve’s Automated Clearing House; as such, collectibility is reasonably assured. The Company records a reserve for doubtful accounts when it is probable that the accounts receivable will not be collected. The Company reviews historical loss experience and the financial position of its customers when estimating the allowance. As of September 30, 2017 and December 31, 2016 , the allowance for doubtful accounts was not material to the Company’s statements of financial position. Customer Incentives Customer incentives represent signing bonuses paid to customers. Customer incentives are paid in connection with the acquisition or renewal of customer contracts, and are therefore deferred and amortized using the straight-line method based on the contractual agreement. Related amortization is recorded as contra-revenue. Property, Equipment and Software—net Property, equipment and software consists of the Company’s facilities, furniture and equipment, software, land and leasehold improvements. These facilities, furniture and equipment and software are depreciated on a straight-line basis over their respective useful lives, which are 15 to 40 years for the Company’s facilities and related improvements, 2 to 10 years for furniture and equipment, 3 to 8 years for software and 3 to 10 years for leasehold improvements or the lesser of the estimated useful life of the improvement or the term of the lease. Also included in property, equipment and software is work in progress consisting of costs associated with software developed for internal use which has not yet been placed in service. Accumulated depreciation as of September 30, 2017 and December 31, 2016 was $379.0 million and $309.7 million , respectively. The Company capitalizes certain costs related to computer software developed for internal use and amortizes such costs on a straight-line basis over an estimated useful life of 5 to 8 years. Research and development costs incurred prior to establishing technological feasibility are charged to operations as such costs are incurred. Once technological feasibility has been established, costs are capitalized until the software is placed in service, at which time the Company begins to amortize such costs over their estimated useful life. Goodwill and Intangible Assets In accordance with ASC 350, Intangibles—Goodwill and Other , the Company tests goodwill for impairment for each reporting unit on an annual basis, or when events occur or circumstances indicate the fair value of a reporting unit is below its carrying value. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that fair value of the goodwill within the reporting unit is less than its carrying value. The Company performed its most recent annual goodwill impairment test for all reporting units as of July 31, 2017 using market data and discounted cash flow analyses. Based on this analysis, it was determined that the fair value of all reporting units were substantially in excess of the carrying value. There have been no other events or changes in circumstances subsequent to the testing date that would indicate impairment of these reporting units as of September 30, 2017 . Intangible assets consist of acquired customer relationships, trade names, customer portfolios and related assets that are amortized over their estimated useful lives. The Company reviews finite lived intangible assets for possible impairment whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. As of September 30, 2017 , there have been no such events or circumstances that would indicate potential impairment of finite lived intangible assets. Settlement Assets and Obligations Settlement assets and obligations result from Financial Institution Services when funds are transferred from or received by the Company prior to receiving or paying funds to a different entity. This timing difference results in a settlement asset or obligation. The amounts are generally collected or paid the following business day. The settlement assets and obligations recorded by Merchant Services represent intermediary balances due to differences between the amount the Sponsoring Member receives from the card associations and the amount funded to the merchants. Such differences arise from timing differences, interchange expenses, merchant reserves and exception items. In addition, certain card associations limit the Company from accessing or controlling merchant settlement funds and, instead, require that these funds be controlled by the Sponsoring Member. The Company follows a net settlement process whereby, if the settlement received from the card associations precedes the funding obligation to the merchant, the Company temporarily records a corresponding liability. Conversely, if the funding obligation to the merchant precedes the settlement from the card associations, the amount of the net receivable position is recorded by the Company, or in some cases, the Sponsoring Member may cover the position with its own funds in which case a receivable position is not recorded by the Company. Derivatives The Company accounts for derivatives in accordance with ASC 815, Derivatives and Hedging . This guidance establishes accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. All derivatives, whether designated in hedging relationships or not, are required to be recorded on the statement of financial position at fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative will be recorded in accumulated other comprehensive income (loss) (“AOCI”) and will be recognized in the statement of income when the hedged item affects earnings. The Company does not enter into derivative financial instruments for speculative purposes. Tax Receivable Agreements As of September 30, 2017 , the Company is party to several TRAs in which the Company agrees to make payments to various parties of 85% of the federal, state, local and foreign income tax benefits realized by the Company as a result of certain tax deductions. Payments under the TRAs will be based on the tax reporting positions of the Company and, generally, are only required to the extent the Company realizes cash savings as a result of the underlying tax attributes. Under the agreement between the Company and Fifth Third dated August 7, 2017, in certain specified circumstances, the Company may be required to make payments in excess of such cash savings. The cash savings realized by the Company are computed by comparing the actual income tax liability of the Company to the amount of such taxes the Company would have been required to pay had there been no deductions related to the tax attributes discussed below. The Company will retain the benefit of the remaining 15% of the cash savings associated with the TRAs. The Company has entered into the following three TRAs: • TRAs with investors prior to the Company’s initial public offering (“IPO”) for its use of NPC Group, Inc. net operating losses (“NOLs”) and other tax attributes existing at the IPO date (the “NPC TRA”), all of which is currently held by Fifth Third. • A TRA with Fifth Third (the “Fifth Third TRA”) in which the Company realizes tax deductions as a result of the increases in tax basis from the purchase of Vantiv Holding units or from the exchange of Vantiv Holding units for cash or shares of Class A common stock, as well as the tax benefits attributable to payments made under such TRAs. • A TRA with Mercury shareholders (the “Mercury TRA”) as part of the acquisition of Mercury as a result of the increase in tax basis of the assets of Mercury resulting from the acquisition and the use of the net operating losses and other tax attributes of Mercury that were acquired as part of the acquisition. Obligations recorded pursuant to the TRAs are based on estimates of future taxable income and future tax rates. On an annual basis, the Company evaluates the assumptions underlying the TRA obligations. In connection with the Fifth Third Exchange and share purchase as discussed in Note 6 - Controlling and Non-controlling Interests, the Company recorded a liability of approximately $647.5 million during the quarter ending September 30, 2017 under the tax receivable agreements the Company entered into with Fifth Third Bank at the time of its initial public offering. This liability is based on the closing share price of the Company’s Class A common stock on August 4, 2017. In 2016, the Company entered into a purchase addendum in connection with the Company’s TRA with Fifth Third (the “Fifth Third TRA Addendum”) to terminate and settle a portion of the Company’s obligations owed to Fifth Third under the Fifth Third TRA and the NPC TRA. Under the terms of the Fifth Third TRA Addendum, the Company paid approximately $116.3 million to Fifth Third to settle approximately $330.7 million of obligations under the Fifth Third TRA, the difference of which was recorded as an addition to paid-in capital, net of deferred taxes. In addition to the 2016 Fifth Third TRA settlement discussed above, as of September 30, 2017, the Fifth Third TRA Addendum provides that the Company may be obligated to pay up to a total of approximately $123.9 million to Fifth Third to terminate and settle certain remaining obligations under the Fifth Third TRA and the NPC TRA, totaling an estimated $275.8 million , the difference of which will be recorded as an addition to paid-in capital upon the exercise of the Call Options or Put Options discussed below. In March, June and September 2017, the Company made payments of $15.1 million , $15.6 million , and $16.1 million , respectively, pursuant to the Fifth Third TRA Holders under the terms of the Fifth Third TRA Addendum. These payments resulted in a net gain recorded in equity of approximately $45.3 million after taxes. As of September 30, 2017, the following are the remaining terms of the Fifth Third TRA Addendum. Beginning December 1, 2017, March 1, 2018, June 1, 2018, September 1, 2018 and December 1, 2018, and ending December 10, 2017, March 10, 2018, June 10, 2018, September 10, 2018 and December 10, 2018, respectively, the Company is granted call options (collectively, the “Call Options”) pursuant to which certain additional obligations of the Company under the Fifth Third TRA and the NPC TRA would be terminated and settled in consideration for cash payments of $16.6 million , $25.6 million , $26.4 million , $27.2 million and $28.1 million , respectively. Under the remaining terms of the Fifth Third TRA Addendum, in the unlikely event the Company does not exercise the relevant Call Option, Fifth Third is granted put options beginning December 20, 2017, March 20, 2018, June 20, 2018, September 20, 2018 and December 20, 2018, and ending December 31, 2017, March 31, 2018, June 30, 2018, September 30, 2018 and December 31, 2018, respectively (collectively, the “Put Options”), pursuant to which certain additional obligations of the Company would be terminated and settled in consideration for cash payments with similar amounts to the Call Options. The full carrying amount of the Fifth Third callable/puttable TRA obligations for the options exercisable within 12 months of the balance sheet date have been classified as current obligations in the accompanying balance sheet ( $216.8 million .) Since Fifth Third is a significant stockholder, a special committee of the Company’s board of directors comprised of independent, disinterested directors authorized the TRA Addendum. During 2015, the Company entered into a Repurchase Addendum to the Mercury Tax Receivable Agreement (the “Mercury TRA Addendum”) with each of the pre-acquisition owners of Mercury ("Mercury TRA Holders"). The Mercury TRA Addendum contains the following provisions to acquire the remaining Mercury TRA: • As of September 30, 2017, the following are the remaining terms under the Mercury TRA Addendum. Beginning December 1 st of each of 2017 and 2018 , and ending June 30 th of 2018 and 2019 , respectively, the Company is granted call options (collectively, the "Call Options") pursuant to which certain additional obligations of the Company under the Mercury TRA would be terminated in consideration for cash payments of $38.0 million and $43.0 million , respectively. • In June 2017 and 2016, the Company exercised the December 2016 and December 2015 Call Options under the Mercury TRA Addendum and made the related $38.1 million and $41.4 million payments to the Mercury TRA Holders. • In the unlikely event the Company does not exercise the relevant Call Option, the Mercury TRA Holders are granted put options beginning July 10th and ending July 25th of each of 2018 and 2019, respectively (collectively, the "Put Options"), pursuant to which certain additional obligations of the Company would be terminated in consideration for cash payments with similar amounts to the Call Options. Except to the extent our obligations under the Mercury TRA, the Fifth Third TRA and the NPC TRA have been terminated and settled in full in accordance with the terms of the Mercury TRA and Fifth Third TRA Addendums, the Mercury TRA, Fifth Third TRA and the NPC TRA will each remain in effect, and the parties thereto will continue to have all rights and obligations thereunder. All TRA obligations are recorded based on the full and undiscounted amount of the expected future payments, except for the Mercury TRA which represents contingent consideration relating to an acquired business, and is recorded at fair value for financial reporting purposes (see Note 8 - Fair Value Measurements).
