Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesContrail Aviation entered into an Operating Agreement (the “Operating Agreement”) in connection with the acquisition of Contrail Aviation in 1996 providing for the governance of and the terms of membership interests in Contrail Aviation and including put and call options with the Seller of Contrail (“Put/Call Option”). The Put/Call Option permits the Seller to require Contrail Aviation to purchase all of the Seller’s equity membership interests in Contrail Aviation commencing on the fifth anniversary of the acquisition, which is on July 18, 2021. The Company has presented this redeemable non-controlling interest in Contrail Aviation between the liabilities and equity sections of the accompanying condensed consolidated balance sheets. In addition, the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying amount of the instrument to equal the redemption value at the end of each reporting period. The fair value of the redeemable non-controlling interest is $5.6 million as of December 31, 2020. The change in the redemption value compared to March 31, 2020 is a net decrease of $0.5 million. The decrease was driven by $1.9 million of net loss attributable to and distributions made to the non-controlling interest as of December 31, 2020, partially offset by a $1.4 million increase related to the net change in fair value during the nine months ended December 31, 2020, which is reflected on our condensed consolidated statements of equity. The offsetting increase is primarily attributable to the value associated with Contrail's potential investment in an aircraft asset management joint venture, as announced publicly in our 8-K dated December 23, 2020.
