Based on current facts and circumstances, the Company believes the unrealized losses presented in the June 30, 2023 securities in a gross unrealized loss position tables above are not indicative of the ultimate collectability of the current amortized cost of the securities, but rather are primarily attributable to changes in risk-free interest rates and a general market widening of credit spreads. In reaching this determination, the Company considered the continued volatility in risk-free rates and credit spreads as well as the fact that its unrealized losses are concentrated in investment grade issuers. Additionally, the Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional impairment losses to be recorded as of June 30, 2023.

The following tables present the activity related to the allowance on available-for-sale securities with credit impairments and purchased credit-deteriorated (PCD) assets. Accrued interest receivable on available-for-sale fixed maturity securities totaled $413 million, $394 million, and $374 million as of June 30, 2023, December 31, 2022, and June 30, 2022 and is excluded from the estimate of expected credit losses and the amortized cost basis in the table included within this Note.

Actual maturities may differ from contractual maturities because certain securities may be called or prepaid. Securities not due at a single date are allocated based on weighted average life.

As part of its overall investment strategy, the Company invests in various assets which require future purchase, sale or funding commitments. These investments are recorded once funded, and the related commitments may include future capital calls from various third-party limited partnerships, signed and accepted mortgage loan applications, and obligations related to private placement securities. As of June 30, 2023, the Company had commitments to purchase or fund approximately $1,480 million and sell approximately $60 million under the terms of these investments.

The following table presents the amortized cost basis of mortgage loans for each credit quality indicator by year of origination. The primary credit quality indicators utilized are debt service coverage ratios (DSCR) and loan-to-value ratios (LTV).

(1) The values in the table above reflect DSCR on a standardized amortization period and LTV based on the most recent appraised values trended forward using changes in a commercial real estate price index.

(2) The amortized cost basis of Mortgage loans as presented in the table above differs from the amount reported in the Condensed Consolidated Balance Sheets because Mortgage loans with a term to maturity of less than one year at the time of origination are classified as Short term investments.

As of June 30, 2023, accrued interest receivable on mortgage loans totaled $4 million and is excluded from the amortized cost basis disclosed in the table above and the estimate of expected credit losses.
