Summary of Amortized Costs and Fair Values of Securities Available-for-sale, by Contractual Maturity

The amortized costs and fair values of available-for-sale securities, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. In addition, expected maturities will differ from contractual maturities for mortgage-backed securities and asset-backed securities, as the expected repayment terms may be less than the underlying mortgage pool contractual maturities. Therefore, these securities are not included in the maturity categories in the maturity summary below.
