Accounting Changes And Error Corrections [Abstract]

Schedule of Accounting Changes

Effective January 1, 2015, FHN retroactively adopted the requirements of ASU 2014-01 with an election to use the proportional amortization method for all qualifying investments. FHN believes the proportional amortization method better represents the economics of its qualified affordable housing investments and provides users with a better understanding of the returns from such investments when compared to the equity method. FHN will continue to use the equity method for non-qualifying affordable housing investments and its other tax credit investments. The cumulative effects of the retrospective application of the change in amortization method are summarized in the tables below.
