Reserves for Reverse Mortgage Interests

The Company records reserves related to reverse mortgage interests based on potential unrecoverable costs and loss exposures expected to be realized. Recoverability is determined based on the Company’s ability to meet HUD servicing guidelines and is viewed as two different categories of expenses: financial and operational. Financial exposures are defined as the cost of doing business related to servicing the HECM product and include potential unrecoverable costs primarily based on HUD claim guidelines related to recoverable expenses and unfavorable changes in the appraised value of the loan collateral. Operational exposures are defined as unrecoverable debenture interest curtailments imposed for missed HUD-specified servicing timelines. Reserves for reverse mortgage interests are related to both financial and operational exposures.
