The Corporation had unpledged Available for Sale securities with a fair value of $ 4.3 billion that could be used to increase its borrowing facilities. The weighted average yield on debt securities available-for-sale is based on amortized cost; therefore, it does not give effect to changes in fair value. Securities not due on a single contractual maturity date, such as mortgage-backed securities and collateralized mortgage obligations, are classified based on the period of final contractual maturity. The expected maturities of collateralized mortgage obligations, mortgage-backed securities and certain other securities may differ from their contractual maturities because they may be subject to prepayments or may be called by the issuer. At June 30, 2025, the Corporation did not intend to sell or believed it was more likely than not that it would be required to sell debt securities classified as available-for-sale. There were no debt securities classified as available-for-sale sold during the six months ended June 30, 2025 and 2024. The following tables present the Corporation’s fair value and gross unrealized losses of debt securities available-for-sale, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2025 and December 31, 2024.

The portfolio of available-for-sale debt securities is comprised mainly of U.S Treasuries and obligations from the U.S. Government, its agencies or government sponsored entities, including Federal National Mortgage Association (“FNMA”), Federal Home Loan Mortgage Corporation (“FHLMC”) and Government National Mortgage Association (“GNMA”). These securities carry an explicit or implicit guarantee from the U.S. Government, are highly rated by major rating agencies, and have a long history of no credit losses. Accordingly, the Corporation applies a zero-credit loss assumption.
