Unrealized losses on investment securities resulted from changes in market interest rates. The Corporation’s portfolio is comprised of securities issued or guaranteed by U.S. government agencies or government-sponsored enterprises. As such, it is expected that the securities would not be settled at a price less than the amortized cost of the investments. Further, the Corporation does not intend to sell the investments, and it is not more-likely-than-not that it will be required to sell the investments before recovery of amortized costs. No allowance for credit losses was recorded on securities in an unrealized loss position at June 30, 2025 or December 31, 2024.

Interest receivable on investment securities totaled $36 million at June 30, 2025 and $38 million at December 31, 2024 and was included in accrued income and other assets on the Consolidated Balance Sheets. The investment securities portfolio included floating-rate securities with a fair value of $3 million at both June 30, 2025 and December 31, 2024.

There were no sales, calls or write-downs of investment securities available-for-sale during the three- and six-month periods ended June 30, 2025 or June 30, 2024.

The following table summarizes the amortized cost and fair values of investment securities by contractual maturity. Securities with multiple maturity dates are classified in the period of final maturity. The actual cash flows of mortgage-backed securities may differ as borrowers of the underlying loans may exercise prepayment options. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
