Maturities

The amortized cost and fair value of held-to-maturity, available-for-sale and trading fixed maturity securities at March 31, 2019, 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.
