Receivables [Abstract] |
Financing Receivables | MORTGAGE LOANS HELD FOR INVESTMENT, NET AND RELATED NON-RECOURSE COLLATERALIZED FINANCINGThe Company's mortgage loans held for investment, net are single-family mortgage loans which were originated or purchased by the Company prior to 2000. As of January 1, 2020, management chose to elect the fair value option in accounting for its mortgage loans held for investment pursuant to the provisions of ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326) Targeted Transition Relief, which was issued in May of 2019. Management chose to elect the fair value option in order to be consistent with the Company’s other investments which are measured at fair value. The election of the fair value option resulted in a cumulative adjustment of $(548) to retained earnings on its consolidated balance sheet as of January 1, 2020. Subsequent changes in fair value are recorded in “gain (loss) on investments, net” on the Company’s consolidated statements of comprehensive income. The amortized cost of the Company’s mortgage loans declined to $6,613 as of December 31, 2020 from $9,501 as of December 31, 2019 due primarily to principal payments. As of December 31, 2020, $2,331 of the principal balance of the Company’s mortgage loans held for investment was pledged as collateral for the one remaining class of the Company's single-family securitization financing bond, which is recorded on the Company's balance sheet as "non-recourse collateralized financing" and had a remaining principal balance of $118. As of December 31, 2019, $3,452 of the principal balance of the Company's mortgage loans held for investment was pledged as collateral for the remaining principal balance of the outstanding bonds of $2,764.
