Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions We have engaged in certain transactions with other companies related to us by common ownership. We have entered into various operating leases to lease office space from an affiliated company. Rent expense related to these leases was $1.8 million and $2.0 million for each of the three months ended June 30, 2016 and 2015, respectively, and $4.5 million and $4.0 million for the six months ended June 30, 2016 and 2015, respectively. We are a party to certain agreements relating to the rental of aircraft to Western Airways ("WA"), an entity owned by the Mosing family. The WA agreements reflect both dry lease and wet lease rental, whereby we are charged a flat monthly fee primarily for crew, hangar, maintenance and administration costs in addition to other variable costs for fuel and maintenance. We also earn charter income from third party usage through a revenue sharing agreement. We recorded net charter expense of $0.5 million and $0.4 million for the three months ended June 30, 2016 and 2015, respectively, and $0.5 million and $0.8 million for the six months ended June 30, 2016 and 2015, respectively. Tax Receivable Agreement MHI and its permitted transferees may convert all or a portion of its Preferred Stock into shares of our common stock on a one-for-one basis, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications and other similar transactions, by delivery of an equivalent portion of its interest in FICV to us (a “Conversion”). FICV has made an election under Section 754 of the Code. Pursuant to the Section 754 election, each future Conversion is expected to result in an adjustment to the tax basis of the tangible and intangible assets of FICV, and these adjustments will be allocated to FINV. Certain of the adjustments to the tax basis of the tangible and intangible assets of FICV described above would not have been available absent these future Conversions. The anticipated basis adjustments are expected to reduce the amount of tax that FINV would otherwise be required to pay in the future. These basis adjustments may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. The tax receivable agreement (the "TRA") that we entered into with FICV and MHI in connection with our IPO generally provides for the payment by FINV of 85% of the amount of the actual reductions, if any, in payments of U.S. federal, state and local income tax or franchise tax (which reductions we refer to as “cash savings”) in periods after our IPO as a result of (i) the tax basis increases resulting from the Conversions and (ii) imputed interest deemed to be paid by us as a result of, and additional tax basis arising from, payments under the TRA. In addition, the TRA provides for payment by us of interest earned from the due date (without extensions) of the corresponding tax return to the date of payment specified by the TRA. We will retain the remaining 15% of cash savings, if any. The payment obligations under the TRA are our obligations and are not obligations of FICV. The term of the TRA will continue until all such tax benefits have been utilized or expired, unless we exercise our right to terminate the TRA. Estimating the amount of payments that may be made under the TRA is by its nature imprecise. The actual increase in tax basis, as well as the amount and timing of any payments under the TRA, will vary depending upon a number of factors, including the timing of Conversions, the relative value of our U.S. and international assets at the time of the Conversion, the price of our common stock at the time of the Conversion, the extent to which such Conversions are taxable, the amount and timing of the taxable income FINV realizes in the future and the tax rate then applicable, FINV’s use of loss carryovers and the portion of its payments under the TRA constituting imputed interest or depreciable or amortizable basis. FINV expects that the payments that it will be required to make under the TRA will be substantial but that it will be able to fund such payments. There may be a negative impact on our liquidity if, as a result of timing discrepancies, the payments under the TRA exceed the actual benefits we realize in respect of the tax attributes subject to the TRA. The payments under the TRA will not be conditioned upon a holder of rights under a TRA having a continued ownership interest in either FICV or FINV. The TRA provides that FINV may terminate it early. If FINV elects to terminate the TRA early, it would be required to make an immediate payment equal to the present value of the anticipated future tax benefits subject to the TRA (based upon certain assumptions and deemed events set forth in the TRA, including the assumption that it has sufficient taxable income to fully utilize such benefits and that any FICV interests that MHI or its transferees own on the termination date are deemed to be exchanged on the termination date). Any early termination payment may be made significantly in advance of the actual realization, if any, of such future benefits. In addition, payments due under the TRA will be similarly accelerated following certain mergers or other changes of control. In these situations, FINV’s obligations under the TRA could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. For example, if the TRA were terminated on June 30, 2016, the estimated termination payment would be approximately $85.6 million (calculated using a discount rate of 4.86%). The foregoing number is merely an estimate and the actual payment could differ materially. Because FINV is a holding company with no operations of its own, its ability to make payments under the TRA is dependent on the ability of FICV to make distributions to it in an amount sufficient to cover FINV’s obligations under such agreements; this ability, in turn, may depend on the ability of FICV’s subsidiaries to provide payments to it. The ability of FICV and its subsidiaries to make such distributions will be subject to, among other things, the applicable provisions of Dutch law that may limit the amount of funds available for distribution and restrictions in our debt instruments. To the extent that FINV is unable to make payments under the TRA for any reason, except in the case of an acceleration of payments thereunder occurring in connection with an early termination of the TRA or certain mergers of change of control, such payments will be deferred and will accrue interest until paid, and FINV will be prohibited from paying dividends on its common stock.
