As of December 31, 2023, Synovus had 12 investment securities in a loss position for less than twelve months and 343 investment securities in a loss position for twelve months or longer. As of December 31, 2023, Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" of this Report for Synovus' policy for evaluating impairment on its investment securities available for sale portfolio. During the fourth quarter of 2023, as part of an overall strategic repositioning of the investment securities portfolio, Synovus sold at amortized cost $1.30 billion of U.S. Treasury securities, U.S. Government agency securities, MBS issued by U.S. Government agencies, MBS issued by U.S. Government sponsored enterprises, and Commercial MBS issued by U.S. Government agencies or sponsored enterprises, which resulted in realized net losses of $77.7 million. Additionally, Synovus purchased $1.28 billion in principal of U.S. Treasury securities, U.S. Government agency securities, MBS issued by U.S. Government agencies, MBS issued by U.S. Government sponsored enterprises, and Commercial MBS issued by U.S. Government agencies or sponsored enterprises. At December 31, 2023, no ACL was established for investment securities. Substantially all of the unrealized losses on the securities portfolio were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. U.S. Treasury and agency securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government, an agency of the United States government, or a government sponsored enterprise. The amortized cost and fair value by contractual maturity of investment securities available for sale at December 31, 2023 are shown below. The expected life of MBSs or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, MBSs and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.
