Management monitors debt securities that are in an unrealized loss position to determine whether a loss exists related to the credit quality of the issuer. When developing an estimate of expected credit losses, management considers all relevant information including historical experience, current conditions, and reasonable forecasts of expected future cash flows. Based on this evaluation, no allowance for credit losses on debt securities was recorded as of April 3, 2022 or December 31, 2021. There was no activity recorded in the allowance for credit losses during the three-month periods ended April 3, 2022 or April 4, 2021. The Company recorded gross realized gains and losses on the sale of debt securities totaling $118,000 and $154,000, respectively, for the three-month period ended April 3, 2022, and no gross realized gains or losses on the sale of debt securities for the three-month period ended April 4, 2021. Realized gains and losses are included in "Investment income" on the Consolidated Statements of Operations. Prior to the sale of these securities, unrealized gains and losses for these debt securities, net of tax, were recorded in shareholders’ equity as accumulated other comprehensive loss.
