Depreciation and amortization of premises and equipment totaled $34 million for both 2019 and 2018, and totaled $32 million in 2017.

During 2019, the Corporation acquired properties as a result of the Huntington branch acquisition which resulted in an increase in the net book value of buildings and improvements from 2018.On January 1, 2019, the Corporation adopted ASU 2016-02 using a modified retrospective approach which required operating leases to be capitalized on the consolidated balance sheets. This resulted in a right-of-use asset of $45 million at December 31, 2019 compared to zero at December 31, 2018. See Note 7 for additional information on operating leases.
