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 $31 million and $32 million as of June 30, 2024 and December 31, 2023, 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. There were no transfers to or from AFS or HTM during the three and six month periods ended June 30, 2024 and 2023.

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 as of both June 30, 2024 and December 31, 2023. FHN has assessed the risk of credit loss and has determined that no allowance for credit losses for HTM securities was necessary as of June 30, 2024 and December 31, 2023. 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 $92 million and $89 million at June 30, 2024 and December 31, 2023, respectively. The year-to-date 2024 and 2023 gross amounts of upward and downward valuation adjustments were not significant.

Unrealized gains of $2 million and $7 million were recognized in the three and six months ended June 30, 2024, respectively, for equity investments with readily determinable fair values. Unrealized gains of $4 million and $6 million were recognized in the three and six months ended June 30, 2023, respectively, for equity investments with readily determinable fair values.
