NON-GAAP FINANCIAL MEASURES
This investor presentation contains certain financial measures that are not measures recognized under U.S. generally accepted accounting principles
(GAAP) and, therefore, are considerednon-GAAP financial measures. Commerce Union’s and Community First’s management use thesenon-GAAP financial measures in their analysis of the performance, financial condition, and efficiency of operations of their respective entities. Management of Commerce Union believes that thesenon-GAAP financial measures provide a greater understanding of ongoing operations, enhance comparability of results with prior periods, and demonstrate the effects of significant gains and charges in the current period. Management also believes that investors find thesenon-GAAP financial measures useful as they assist investors in understanding underlying operating performance and the analysis of ongoing operating trends. However, thenon-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which thenon-GAAP financial measures discussed herein are calculated may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar to, or with names similar to, thenon-GAAP financial measures we have discussed herein when comparing suchnon-GAAP financial measures.
This presentation contains certainnon-GAAP financial measures, including, without limitation, tangible assets, tangible book value, tangible common equity, return on average tangible common equity, tangible common equity to assets, efficiency ratio, core income return on average assets, and core income return on average equity. A reconciliation of thesenon-GAAP financial measures to the most directly comparable GAAP measures are provided in
the appendix to this presentation.
