Actual maturities of our investment securities available for sale are generally shorter than stated contractual maturities (with contractual maturities up to 37 years), as they are affected by periodic payments and prepayments of principal on the underlying mortgages. As of December 31, 2022 and 2021, based on management’s estimates, the weighted average life of the Company’s investment securities available for sale portfolio was approximately 7.6 years and 5.8 years, respectively.

At December 31, 2022, the Company did not intend to sell any of its investment securities available for sale that were in an unrealized loss position, and it was “more likely than not” that the Company would not be required to sell these securities before recovery of their amortized cost basis, which may be at their maturity.

Credit risk associated with non-Agency RMBS is regularly assessed as new information regarding the underlying collateral becomes available and based on updated estimates of cash flows generated by the underlying collateral. In performing its assessment, the Company considers past and expected future performance of the underlying collateral, including timing of expected future cash flows, prepayment rates, default rates, loss severities, delinquency rates, current levels of subordination, volatility of the security's fair value, temporary declines in liquidity for the asset class and interest rate changes since purchase. Based upon the most recent evaluation, the Company does not believe that these unrealized losses are credit related but are rather a reflection of current market yields and/or marketplace bid-ask spreads.
