(1)The amortization expense for the LIHTC and FHTC investments is included in our income tax expense. Prior to the adoption of ASU 2023-02 on January 1, 2024, FHTC amortization expense was included in noninterest expense. NMTC amortization is recognized in noninterest expense in correlation to the recognition of tax credits on our tax return. Amortization expense for the Renewable Energy tax credits is included in noninterest expense. (2)All of the tax benefits recognized are included in our income tax expense. The tax benefit recognized for the NMTC and Renewable Energy investments primarily reflects the tax credits generated from the investments and excludes the net tax expense (benefit) and deferred tax liability of the investments’ income (loss).
