The Corporation had unpledged Available for Sale securities with a fair value of $ 6.4 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 in 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. The following table presents the aggregate amortized cost and fair value of debt securities available-for-sale at December 31, 2023 by contractual maturity. (In thousands) Amortized cost Fair value Within 1 year $ 7,105,166 $ 7,046,274 After 1 to 5 years 3,699,918 3,525,430 After 5 to 10 years 1,120,446 1,037,788 After 10 years 6,175,633 5,119,552 Total debt securities available-for-sale $ 18,101,163 $ 16,729,044 At December 31, 2023, 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 available-for-sale sold during the years ended December 31, 2023 and December 31, 2022. During the year ended December 31, 2021, the Corporation sold U.S Treasury Notes. The proceeds from these sales were $ 236 million. Gross realized gains and losses on the sale of debt securities available-for-sale for the years ended December 31, 2023, 2022 and 2021 were as follows: (In thousands) 2023 2022 2021 Gross realized gains $ - $ - $ 695 Gross realized losses - - (672) Net realized gains (losses) on sale of debt securities available -for-sale $ - $ - $ 23 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 December 31, 2023 and 2022.

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 FNMA, FHMLC and GNMA. As discussed in Note 2 to the Consolidated Financial Statements, 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 and no ACL for these securities has been established. In October 2022, the Corporation transferred U.S. Treasury securities with a fair value of $ 6.5 billion (par value of $ 7.4 billion) from its available-for-sale portfolio to its held-to-maturity portfolio. Management changed its intent, given its ability to hold these securities to maturity due to the Corporation’s liquidity position and its intention to reduce the impact on accumulated other comprehensive income (loss) (“AOCI”) and tangible capital of further increases in interest rates. The securities were reclassified at fair value at the time of the transfer. At the date of the transfer, these securities had pre-tax unrealized losses of $ 873 million recorded in AOCI. This fair value discount is being accreted to interest income and the unrealized loss remaining in AOCI is being amortized, offsetting each other through the remaining life of the securities. There were no realized gains or losses recorded as a result of this transfer.
