Distribution of the Company's fixed maturity portfolio by estimated expected maturity

The following table presents the distribution of the Company’s fixed maturity securities portfolio by estimated expected maturity. Estimated expected maturities differ from contractual maturities, reflecting assumptions regarding borrowers’ utilization of the right to call or prepay obligations with or without call or prepayment penalties. For structured securities, including mortgage-backed securities and other asset-backed securities, estimated expected maturities consider broker-dealer survey prepayment assumptions and are verified for consistency with the interest rate and economic environments.

		June 30,					December 31,					Fair					Amortized
