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 $1.7 million and $1.8 million for the three months ended June 30, 2017 and 2016, respectively, and $3.5 million and $4.5 million for the six months ended June 30, 2017 and 2016, 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 $0.7 million and $0.5 million of net charter expense for the three months ended June 30, 2017 and 2016, respectively, and $0.6 million and $0.5 million of net charter expense for six months ended June 30, 2017 and 2016, respectively. During the first quarter of 2017, we committed to a formal plan to sell two aircraft and determined those assets met the criteria to be classified as held for sale in our unaudited condensed consolidated balance sheet. Tax Receivable Agreement Mosing Holdings and its permitted transferees converted all of their Preferred Stock into shares of our common stock on a one-for-one basis on August 26, 2016, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications and other similar transactions, by delivery of an equivalent portion of their interests in FICV to us (the “Conversion”). FICV will make an election under Section 754 of the Internal Revenue Code. Pursuant to the Section 754 election, the Conversion will result in an adjustment to the tax basis of the tangible and intangible assets of FICV with respect to the portion of FICV now held by FINV. These adjustments will be allocated to FINV. The adjustments to the tax basis of the tangible and intangible assets of FICV described above would not have been available absent this Conversion. The 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 Mosing Holdings in connection with our initial public offering ("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 Conversion 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. The payments under the TRA will not be conditioned upon a holder of rights under the TRA having a continued ownership interest in either FICV or FINV. We will retain the remaining 15% of cash savings, if any. As of both June 30, 2017 and December 31, 2016, our estimated TRA liability was $124.6 million. This represents 85% of the future cash savings expected from the utilization of the original basis adjustments plus subsequent basis adjustments that will result from payments under the TRA agreement. The estimation of the TRA liability is by its nature imprecise and subject to significant assumptions regarding the amount and timing of taxable income in the future and the tax rates then applicable. The time period over which the cash savings is expected to be realized is estimated to be over 20 years. Based on FINV’s estimated tax position, we expect to make a TRA payment in 2017 of approximately $2.1 million for the tax year ending December 31, 2016. 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 FINV elects to exercise its sole right to terminate the TRA early. If FINV elects to terminate the TRA early, which it may do so in its sole discretion, 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 Mosing Holdings 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, 2017, the estimated termination payment would be approximately $100.8 million (calculated using a discount rate of 5.61%). 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 or 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.
