Schedule of Maturities

The amortized cost and fair value of available-for-sale fixed maturity securities at September 30, 2022, by contractual maturity, are shown in the following tables. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Asset-backed securities, mortgage-backed securities and collateralized mortgage obligations may be subject to prepayment risk and are therefore not categorized by contractual maturity.

Summary of Fixed Maturity Securities in an Unrealized Loss Position

The following tables summarize our fixed maturity securities that were in an unrealized loss position reported on a consolidated basis at September 30, 2022 and December 31, 2021. The securities are presented by the length of time they have been continuously in an unrealized loss position. Non-credit related unrealized losses are recognized as a component of other comprehensive income and represent other market movements that are not credit related, for example interest rate changes. We have no intent to sell, and it is more likely than not that we will not be required to sell, these securities until the fair value recovers to at least equal our cost basis or the securities mature.
