We do not consider the unrealized losses to be credit-related, as these unrealized losses primarily relate to changes in interest rates and market spreads subsequent to purchase. We do not have plans to sell any of the available-for-sale debt securities with unrealized losses as of March 31, 2026, and we believe it is more likely than not that we would not be required to sell such available-for-sale debt securities before recovery of their amortized cost. We continue to monitor unrealized loss positions for potential credit impairments. During the three months ended March 31, 2026 and 2025, there were no credit impairments related to our investment securities. The amortized cost and fair value of our debt securities by contractual maturity as of March 31, 2026 are summarized in the following table. Maturities are based on the final contractual payment dates and do not reflect the impact of prepayments or earlier redemptions that may occur. | | | | | | | | | | | | | Amortized
