Fair Value Of Financial Instruments [Abstract]
Fair Value Of Financial Instruments	(13) Fair Value of Financial Instruments The carrying amounts of cash, restricted cash, accounts receivable and accounts payable reflected in the balance sheets as of December 31, 2019 and 2018, approximate their fair value due to the short-term nature of these financial assets and liabilities. The carrying value of variable rate debt in the balance sheets as of December 31, 2019 and 2018 approximates fair value as the changes in their associated interest rates reflect the current market and credit risk is similar to when the loans were originally obtained. The principal balance of the Company’s fixed-rate term loans, asset-backed notes and collateralized financing obligations was $148.4 million, $898.2 million and $91.3 million as of December 31, 2019, with a fair value of approximately $151.0 million, $911.0 million and $93.0 million, respectively, based on the fair value of estimated future payments calculated using prevailing interest rates. The fair value of these financial instruments would be categorized as Level 2 in the fair value hierarchy. The principal balance of the Company’s asset-backed notes and collateralized financing obligations was $1,032.7 million and $107.2 million as of December 31, 2018, with a fair value of approximately $1,024.7 million and $108.9 million, respectively. Management believes that the balances of the Company’s senior secured notes of $52.8 million and $58.9 million and term loans held by VIE of $36.5 million and $1.5 million as of December 31, 2019 and 2018, respectively, fixed-rate term loans of $158.6 million as of December 31, 2018, and financing receivable of $34.4 million as of December 31, 2019, approximate their fair values. The fair value of these financial instruments would be categorized as Level 2 in the fair value hierarchy.
