Participating Interests in HMBS Participating interests in HMBS consist of the Company’s reverse mortgage interests in HECM loans which have been transferred to GNMA and subsequently securitized through the issuance of HMBS. The Company does not own these loans, but due to HMBS program buyout requirements, such interests are consolidated in the Company’s consolidated balance sheets. The Company does not originate reverse mortgages, but during the year ended December 31, 2019 and five months ended December 31, 2018, a total of $265 and $107 in UPB associated with new draws on existing loans were transferred to GNMA and securitized by the Company, respectively. During the seven months ended July 31, 2018 a total of $198 in UPB was transferred to GNMA and securitized by the Predecessor. In March 2019, the Company entered into an agreement with Fannie Mae for the transfer of reverse mortgage loans. As a result, $61 was transferred from Fannie Mae and securitized into GNMA HMBS during the year ended December 31, 2019. Other Interests Securitized Other interests securitized consist of reverse mortgage interests that no longer meet HMBS program eligibility criteria primarily because they have reached 98% of their MCA, which is established at origination and in accordance with HMBS program guidelines, requiring a repurchase of loans from the respective HMBS trust. These reverse mortgage interests have subsequently been transferred to private securitization trusts and are accounted for as a secured borrowing. During the year ended December 31, 2019, the Company securitized a total of $751 UPB through Trust 2019-1 and Trust 2019-2 and a total of $476 UPB from Trust 2017-2 and Trust 2018-1 was called and the related debt was extinguished. The Company sold $20 UPB of Trust 2018-3 retained bonds during the year ended December 31, 2019. During the five months ended December 31, 2018, the Company securitized a total of $364 UPB through Trust 2018-3 and a total of $188 UPB from Trust 2017-1 was called and the related debt was extinguished. During the seven months ended July 31, 2018, the Predecessor securitized a total of $760 UPB through Trust 2018-1 and Trust 2018-2 and a total of $284 UPB from Trust 2016-2 and Trust 2016-3 was called and the related debt was extinguished.

(1) | HECM related receivables consist primarily of receivables from FNMA for corporate advances and service fees and claims receivables from the U.S. Department of Housing and Urban Development on reverse mortgage interests.
Unsecuritized interests include repurchased HECM loans for which the Company is required to repurchase from the HMBS pool when the outstanding principal balance of the HECM loan is equal to or greater than 98% of the MCA established at origination in accordance with HMBS program guidelines. These unsecuritized interests are primarily financed through available warehouse lines. The Company repurchased a total of $2,333 and $1,429 of HECM loans out of GNMA HMBS securitizations during the year ended December 31, 2019 and five months ended December 31, 2018, respectively, of which $616 and $328 were subsequently assigned to a third party in accordance with applicable servicing agreements, respectively. The Predecessor repurchased a total of $2,439 of HECM loans out of GNMA HMBS securitizations during the seven months ended July 31, 2018, of which, $512 was subsequently assigned to a third party in accordance with applicable servicing agreements. To the extent a loan is not subject to applicable servicing agreements and assigned to a third party, the loan is either subject to assignment to HUD, per contractual obligations with GNMA, liquidated via a payoff from the borrower or liquidated via a foreclosure according to the terms of the underlying mortgage. The Company assigned a total of $1,819 and $1,493 of HECM loans to HUD during the year ended December 31, 2019 and five months ended December 31, 2018, respectively.
