For periods subsequent to 2019, 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 because the primary cause of the decline in value was attributable to changes in interest rates. Total AIR not included in the fair value or amortized cost basis of AFS debt securities was $21.8 million as of September 30, 2020. 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 period. 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 period.

For periods prior to 2020, FHN reviewed debt investment securities that were in unrealized loss positions in accordance with its accounting policy for OTTI and did not consider them other-than-temporarily impaired.

For debt securities with unrealized losses, FHN did not intend to sell them and it is more-likely-than-not that FHN would not be required to sell them prior to recovery. The decline in value was primarily attributable to changes in interest rates and not credit losses.

The carrying amount of equity investments without a readily determinable fair value was $55.2 million and $25.6 million at September 30, 2020 and December 31, 2019, respectively. The year-to-date 2020 and 2019 gross amounts of upward and downward valuation adjustments were not significant.

Unrealized gains of $1.2 million and $0.4 million were recognized in the three months ended September 30, 2020 and 2019, respectively, and unrealized losses of $3.6 million and unrealized gains of $4.9 million were recognized in the nine months ended September 30, 2020 and 2019, respectively, for equity investments with readily determinable fair values.
