FHN has evaluated all AFS debt securities that were in unrealized loss positions in accordance with its accounting policy for recognition of credit losses. No AFS debt securities were determined to have credit losses. Total AIR not included in the fair value or amortized cost basis of
AFS debt securities was $32 million and $23 million as of December 31, 2022 and 2021, respectively. Consistent with FHN's review of the related securities, there were no credit-related write downs of AIR for AFS debt securities during the reporting periods. Additionally, for AFS debt
securities with unrealized losses, FHN does not intend to sell them and it is more-likely-than-not that FHN will not be required to sell them prior to recovery. Therefore, no write downs of these investments to fair value occurred during the reporting periods.
For HTM securities, an allowance for credit losses is required to absorb estimated lifetime credit losses. Total AIR not included in the fair value or amortized cost basis of HTM debt securities was $3 million and $1 million as of December 31, 2022 and 2021, respectively. FHN has assessed the risk of credit loss and has determined that no allowance for credit losses for HTM securities was necessary as of December 31, 2022 and 2021. The evaluation of credit risk includes consideration of third-party and government guarantees (both explicit and implicit), senior or subordinated status, credit ratings of
the issuer, the effects of interest rate changes since purchase and observable market information such as issuer-specific credit spreads.
The carrying amount of equity investments without a readily determinable fair value was $79 million and $70 million at December 31, 2022 and 2021, respectively. The year-to-date 2022 and 2021 gross amounts of upward and downward valuation adjustments were not significant.
Unrealized losses of $11 million and unrealized gains of $3 million and $7 million were recognized during 2022, 2021 and 2020, respectively, for equity investments with readily determinable fair values.
