Investment Securities Available for Sale, at Fair Value

5. Investment Securities Available For Sale, at Fair Value

The Company accounts for certain of its investment securities available for sale using the fair value election pursuant to ASC 825, Financial Instruments ("ASC 825"), where changes in fair value are recorded in unrealized gains (losses), net on the Company's condensed consolidated statements of operations. The Company also has investment securities available for sale where the fair value option has not been elected, which we refer to as CECL Securities. CECL Securities are reported at fair value with unrealized gains and losses recorded in other comprehensive income (loss) on the Company's condensed consolidated statements of comprehensive income (loss). The Company's investment securities available for sale consisted of the following as of March 31, 2023 and December 31, 2022, respectively (dollar amounts in thousands):

Weighted Average Life

Actual maturities of our investment securities available for sale are generally shorter than stated contractual maturities (with contractual maturities up to 36 years), as they are affected by periodic payments and prepayments of principal on the underlying mortgages. As of March 31, 2023 and December 31, 2022, based on management’s estimates, the weighted average life of the Company’s investment securities available for sale portfolio was approximately 8.6 years and 7.6 years, respectively.

The following table sets forth the weighted average lives of our investment securities available for sale as of March 31, 2023 and December 31, 2022, respectively (dollar amounts in thousands):

Unrealized Losses in Other Comprehensive Income (Loss)

The Company evaluated its CECL Securities that were in an unrealized loss position as of March 31, 2023 and December 31, 2022, respectively, and determined that no allowance for credit losses was necessary. The Company did not recognize credit losses for its CECL Securities through earnings for the three months ended March 31, 2023 and 2022.

The following table presents the Company's CECL Securities in an unrealized loss position with no credit losses reported, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of March 31, 2023 and December 31, 2022, respectively (dollar amounts in thousands):

Total	$	23,609	$	(1,966)	$	36	$	(5)	$	23,645	$	(1,971)

At March 31, 2023, 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.
