(1)The weighted average input values for all loan types are based on unpaid principal balance. The weighted average input values for all other assets and liabilities are based on relative fair value. (2)Values represent pricing inputs used in securitization pricing model. Credit spreads represent spreads to applicable swap rates unless specified otherwise. (3)The fair value of the loans and HEI held by consolidated entities is based on the fair value of the ABS issued by these entities and the securities and other investments we own in those entities, which we determined were more readily observable in accordance with accounting guidance for collateralized financing entities. At September 30, 2023, the fair value of securities we owned at the consolidated Sequoia, CAFL SFR, Freddie Mac SLST, Freddie Mac K-Series, and HEI securitization entities was $206 million, $316 million, $256 million, $33 million, and $15 million, respectively. (4)Represents the estimated average duration of outstanding servicer advances at a given point in time (not taking into account new advances made with respect to the pool).
