The corporate securities category had gross unrealized losses greater than twelve months of $37 million as of December 31, 2021, excluding losses of $1 million that were considered credit related. These losses are deemed temporary due to positive factors supporting the recoverability of the respective investments. Positive factors considered include credit ratings, the financial health of the issuer, the continued access of the issuer to capital markets, interest rate movement, and other pertinent information.

As of December 31, 2021, the Company had a total of 742 positions that were in an unrealized loss position, including 5 positions for which an allowance for credit losses was established. For unrealized losses for which an allowance for credit losses was not established, the Company does not consider these unrealized loss positions to be credit related. This is based on the aggregate factors discussed previously and because the Company has the ability and intent to hold these investments until the fair values recover. The Company does not intend to sell or expect to be required to sell the securities before recovering the Company’s amortized cost of the securities.
