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 req uirements, such interests are consolidated in the Company’s consolidated balance sheets. The Company does not originate reverse mortgages, but during the years ended December 31, 2020 and 2019, a total of $173 and $265 in UPB associated with new draws on existing loans were transferred to GNMA and securitized by the Company, respectively. 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. There was no such activity during the year ended December 31, 2020. Other Interests Securitized Other interests securitized consist of reverse mortgage interests that no longer meet HMBS program eligibility criteria primarily because they are equal to or greater than 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, 2020, the Company securitized a total of $516 UPB through Trust 2020-1 and called a total of $337 UPB from Trust 2018-2 and Trust 2018-3 with the related debt being extinguished. During the year ended December 31, 2019, the Company securitized a total of $751 UPB through Trust 2019-1 and Trust 2019-2 and called a total of $476 UPB from Trust 2017-2 and Trust 2018-1 with the related debt being extinguished. The Company sold $20 UPB of Trust 2018-3 retained bonds during the year ended December 31, 2019. Refer to Other Nonrecourse Debt in Note 12, Indebtedness, for additional information. Unsecuritized Interests Unsecuritized interests in reverse mortgages consists of the following:

Repurchased HECM loans (exceeds 98% MCA) | $ | 665 |  |  | $ | 789 |

REO related receivables | 19 |  |  | 14 |
Total unsecuritized interests | $ | 964 |  |  | $ | 1,117 |
(1)HECM related receivables consist primarily of receivables from FNMA for corporate advances and service fees and claims receivables from HUD 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 guidelin es. These unsecuritized interests are primarily financed through available warehouse lines. The Company repurchased a total of $1,153 and $2,333 of HECM loans out of GNMA HMBS securitizations during the years ended December 31, 2020 and 2019, respectively, of which $306 and $616 were subsequently assigned to a third party in accordance with applicable servicing agreements, respectively. 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 $771 and $1,819 of HECM loans to HUD during the years ended December 31, 2020 and 2019, respectively. Purchase Discount, net, for Reverse Mortgage Interests In connection with the Merger, the Company recorded the acquired reverse mortgage interests at estimated fair value as of the acquisition date, which resulted in a net purchase discount of $256 associated with financial and operational losses on reverse mortgage interests associated with servicing the loans through foreclosure and collateral liquidation. The premium and discount are amortized and accreted, respectively, based on the effective yield method, whereby the Company updates its prepayment assumptions for actual prepayments on a quarterly basis. Consistent with the Company’s accounting policy, the Company calculates reserve requirements on the reverse mortgage interests portfolio each reporting period and compares such calculated reserve requirements against the remaining net purchase discount. If the calculated reserve requirements exceed the remaining net purchase discount, the Company will record an additional reserve and associated provision to general and administrative expense. No additional reserves were required to be recorded as of December 31, 2020. The following table sets forth the activities of the purchase discounts, net, for reverse mortgage interests:

Credit Loss for Reverse Mortgage Interests As described in Note 1, Nature of Business and Basis of Presentation, reverse mortgage interests are within the scope of ASU 2016-13, requiring an assessment of reserves regarding credit-related losses in accordance with the CECL framework. Upon applying ASU 2016-13, the Company determined that credit-related losses are immaterial given the government insured nature of the HECM loan product. Any expected credit-related losses are contemplated in the Company’s existing reserve methodology due to the nature of this financial ins trument. Accordingly, no cumulative effect adjustment was required upon adoption of ASU 2016-13 on January 1, 2020 and no additional CECL reserve was recorded as of December 31, 2020. The credit-risk characteristics of reverse mortgage interests do not vary with time as the financial instruments have no contractual life or financial profile as the primary counterparty is the government agency insuring the loans. Reverse Mortgage Interests Income The Company accrues interest income for its participating interest in reverse mortgages based on the stated rates underlying HECM loans and FHA guidelines. Total interest earned on the Company’s reverse mortgage interests was $200 and $307 for the years ended December 31, 2020 and 2019, respectively.
