Unrealized losses in agency mortgage-backed securities, beneficial interests in FHLMC securitizations, and other securities have not been recognized into income because the issuer bonds are of high credit quality, management does not intend to sell, it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in discount rates and assumptions regarding future interest rates. The fair value is expected to recover as the bonds approach maturity. The assessment of determining if a decline in fair value resulted from a credit loss is performed at the individual security level. Among other factors considered are: 1) the extent to which the fair value is less than the amortized cost basis; 2) the financial condition and near term prospects of the issuer, including consideration of relevant financial metrics or ratios of the issuer; 3) any adverse conditions related to an industry or geographic area of an issuer; 4) any changes to the rating of the security by a

rating agency; and 5) any past due principal or interest payments from the issuer. If an assessment of the above factors indicates that a credit loss exists, the Company records an allowance for credit losses for the excess of the amortized cost basis over the present value of cash flows expected to be collected, limited to the amount that the security's fair value is less than its amortized cost basis. Subsequent changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized in earnings. Any interest received after the security has been placed on nonaccrual status is recognized on a cash basis.

Due to higher than expected prepayments on an underlying 2016 securitization, especially during the last three quarters, the value of an interest only strip security became impaired and we were required to reduce the value of the security by $1.8 million. The impairment was included as a charge in provision for credit losses on the consolidated income statement.

The scheduled maturities of securities AFS and the related weighted average yields were as follows for the periods indicated:

Agency mortgage-backed securities and beneficial interests in FHLMC securitizations are excluded from the above table because such securities are not due at a single maturity date. The weighted average yield of the agency mortgage-backed securities and beneficial interests as of March 31, 2020 was 2.37%.
