current yield for total investment securities available for sale increased from 2.66% at    December 31, 2023 to 4.30% at December 31, 2024, while the weighted-average duration of that portfolio increased from 1.3 years to 2.6 years at each of those respective dates. The Company sold $181 million of non-agency investment securities from its available-for-sale portfolio and its remaining equity investments in Fannie Mae and Freddie Mac preferred securities in 2024. The Company routinely adjusts its holdings of capital stock of the FHLB of New York and the FRB of New York based on amounts of outstanding borrowings and available lines of credit with those entities. 

The Company regularly reviews its debt investment securities for declines in value below amortized cost that might be indicative of credit-related losses. In light of such reviews, there were no credit-related losses on debt investment securities recognized in 2024, 2023 and 2022. A further discussion of fair values of investment securities is included herein under the heading "Capital." Additional information about the investment securities portfolio is included in notes 3 and 19 of Notes to Financial Statements.

Other earning assets include interest-bearing deposits at banks and trading account assets. Those other earning assets in the aggregate averaged $27.3 billion in 2024 and $26.3 billion in 2023 and were primarily comprised of deposits held at the FRB of New York. In general, the levels of those deposits often fluctuate due to changes in deposits of retail and commercial customers, trust-related deposits, brokered deposits and additions to or maturities of investment securities or borrowings.

Average core deposits represented 77% of average earning assets in 2024, compared with 79% in 2023. The Company also includes brokered deposits as a component of its wholesale funding strategy
