For AFS securities, the Firm believes there are no securities in an unrealized loss position that have credit losses after performing the analysis described in Note 2 in the 2024 Form 10-K and the Firm expects to recover the amortized cost basis of these securities. Additionally, the Firm does not intend to sell these securities and is not likely to be required to sell these securities prior to recovery of the amortized cost basis. As of September 30, 2025 and December 31, 2024, the securities in an unrealized loss position are predominantly investment grade.

The HTM securities net carrying amounts at September 30, 2025 and December 31, 2024 reflect an ACL of $62 million and $52 million, respectively, predominantly related to Non-agency CMBS. See Note 2 in the 2024 Form 10-K for a description of the ACL methodology used for HTM Securities.

As of September 30, 2025 and December 31, 2024,97% of the Firm’s portfolio of HTM securities were investment grade U.S. agency securities, U.S. Treasury securities and Agency CMBS, which were on accrual status and for which there is an underlying assumption ofzero credit losses. Non-investment grade HTM securities primarily consisted of certain Non-agency CMBS securities, for which the expected credit losses were insignificant and were predominantly on accrual status at September 30, 2025 and December 31, 2024.

See Note 14 for additional information on securities issued by VIEs, including U.S. agency mortgage-backed securities, non-agency CMBS, and FFELP student loan ABS.
