The Company monitors its investment securities available for sale for credit loss impairment on an individual security basis. No securities were determined to be credit loss impaired during the year ended December 31, 2021. An ACL was recorded related to one private label commercial MBS security during the year ended December 31, 2020. At December 31, 2021, the Company did not have an intent to sell securities that were in unrealized loss positions and it was not more likely than not that the Company would be required to sell these securities before recovery of the amortized cost basis, which may be at maturity. In making this determination, the Company considered its current and projected liquidity position, its investment policy as to permissible holdings and concentration limits, regulatory requirements and other relevant factors. At December 31, 2021, 244 securities available for sale were in unrealized loss positions. The unrealized losses are primarily attributable to changes in interest rates and widening spreads, signaling market anticipation of changes in monetary policy. The amount of impairment related to 72 of these securities was considered insignificant both individually and in the aggregate, totaling approximately $0.6 million and no further analysis with respect to these securities was considered necessary. For U.S. Government, U.S. government agency and U.S. government sponsored enterprise securities, the timely payment of principal and interest is explicitly or implicitly guaranteed by the U.S. Government. As such, there is an assumption of zero credit loss and the Company expects to recover the entire amortized cost basis of these securities. For all other AFS securities in a significant unrealized loss position, the Company performed an analysis by first determining the present value of cash flows expected to be collected, based on an economic scenario calibrated to be more severe than our reasonable and supportable economic forecast. The present value was then compared to the amortized cost basis to identify possible impairment. The analysis incorporated assumptions about voluntary prepayment rates, collateral defaults, delinquencies, severity, recovery lag and other relevant factors. Our analysis also considered the structural characteristics of each security and the level of credit enhancement provided by that structure.
