FHN has reviewed investment securities that were in unrealized loss positions in accordance with its accounting policy for OTTI and does not consider them other-than-temporarily impaired. For 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. The decline in value is primarily attributable to changes in interest rates and not credit losses. For equity securities, FHN has both the ability and intent to hold these securities for the time necessary to recover the amortized cost.
