Contractual Maturities, Amortized Cost, Carrying Values, and Current Yields for Available-For-Sales Securities
The following table details the contractual maturities, amortized costs, carrying values and current yields for our available-for-sale securities.  Since our MBS and CMO available-for-sale securities are backed by mortgages, actual maturities may differ from contractual maturities because borrowers may have the right to prepay obligations without prepayment penalties. As a result, as of December 31, 2021, the weighted-average life of our available-for-sale securities portfolio was approximately four years.
