We deposit bonds with insurance regulatory authorities to meet statutory requirements. The adjusted cost of bonds on deposit with insurance regulatory authorities was $21.4 million and $27.1 million as of December 31, 2022 and March 31, 2022, respectively.

The gross realized gains on these sales totaled $ 1.1 million during the first nine months of fiscal 2023 and $ 9.5 million for the full year of fiscal 2022. The gross realized losses on these sales totaled $ 0.5 million during the first nine months of fiscal 2023 and $ 1.4 million for the full year of fiscal 2022. For available-for-sale debt securities in an unrealized loss position, we first assess whether the security is below investment grade. For securities that are below investment grade, we evaluate whether the decline in fair value has resulted from credit losses or other factors such as the interest rate environment. Declines in value due to credit quality are recognized as an allowance. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse market conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, cumulative default rates based on ratings are used to determine the potential cost of default, by year. The present value of these potential costs is then compared to the amortized cost of the security to determine the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through accumulated other comprehensive income, net of applicable taxes. If we intend to sell a security, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis, the security is written down to its fair value and the write down is charged against the allowance for credit losses, with any incremental impairment reported in earnings. Reversals of the allowance for credit losses are permitted and should not exceed the allowance amount initially recognized. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. There was a $ 2.2 million net impairment charge recorded in the first nine months ended December 31, 2022. The adjusted cost and estimated market value of available-for-sale investments by contractual maturity were as follows: December 31, 2022 March 31, 2022 Cost Amortized Market Value Estimated Cost Amortized Market Value Estimated (Unaudited) (In thousands) Due in one year or less $ 333,984 $ 333,803 $ 97,969 $ 99,432 Due after one year through five years 602,861 575,794 541,840 570,135 Due after five years through ten years 756,691 674,055 704,295 765,073 Due after ten years 919,765 746,989 995,904 1,056,295 2,613,301 2,330,641 2,340,008 2,490,935 Mortgage-backed securities 375,819 332,887 324,029 330,157 $ 2,989,120 $ 2,663,528 $ 2,664,037 $ 2,821,092 As of December 31, 2022 and March 31, 2022, our common stock and non-redeemable preferred stock that are included in Investments, fixed maturities and marketable equities on our balance sheet are stated in the table below.
