Schedule of Investment Securities Maturity Information
The following table provides the amortized cost and fair value by contractual maturity. Expected maturities will differ from contractual maturities on certain securities because borrowers and issuers may have the right to call or prepay obligations with or without prepayment penalties. Residential and commercial mortgage-backed and government agency securities are stated separately as they are not due at a single maturity date.
