​ At December 31, 2022, the Company’s investments include asset-backed securities totaling $160.8 million that are backed by student loans originated under the Federal Family Education Loan program (“FFEL”). Under the FFEL, private lenders made federally guaranteed student loans to parents and students. While the program was modified several times before elimination in 2010, FFEL securities are generally guaranteed by the U.S. Department of Education (“DOE”) at not less than 97% of the principal amount of the loans. The guarantee will reduce to 85% if the DOE receives reimbursement requests in excess of 5% of insured loans; reimbursement will drop to 75% if reimbursement requests exceed 9% of insured loans. As of December 31, 2022, the likelihood of the decrease in the government guarantee was minimal as the average rate of reimbursement for 2022 was less than 1.0%. ​ As of December 31, 2022, the Company has no securities issued from one originator, other than the U.S. Government and its agencies, that individually amounted to over 10% of the Company’s stockholders equity. ​ Securities with unrealized losses with no corresponding allowance for credit losses at December 31, 2022 and 2021, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, were as follows (in thousands except for number of securities): ​

​ Available-for-sale debt securities in unrealized loss positions are evaluated for allowance related to credit losses at least quarterly. T he analysis consists of screening all securities to determine if the bonds have market value loss exceeding 5% of book value and if that loss exceeds $200,000. Two other aspects of each security are assessed. The first is whether a security carries a government guarantee. If the security is backed by a 100% U.S. Government or U.S. Agency guarantee, then no allowance for credit loss would be considered necessary, since ultimately principal and interest of the investment would be paid. For securities that carried a U.S. Government guarantee of less than 100%, an allowance for credit loss analysis is performed. In the case of a partial government guarantee, the loss amount is assumed to be the percentage not guaranteed multiplied by the gain or loss on the position. In addition, a calculation is performed to estimate the amount of value change attributable to movements in interest rates. If the devaluation of a security is largely due to rate changes, then no allowance would be considered necessary. However, if a payment collected on a particular bond is less than the expected amount, individual credit analysis is conducted on that position. Furthermore, for positions whose market valuations are not directly attributable to movements in interest rates, even if all scheduled payments have been received, credit analysis is performed on each position. ​ The following table presents net realized gains (losses) on securities available-for-sale for the years ended: ​
