[1] Reclassified to conform to the current period’s presentation. Reclassifications consisted of disaggregating fee revenue previously presented in “Service charges and other fees” and certain revenue previously presented in “Other” into the presentation above. The Company made these reclassifications to provide additional information about its sources of noninterest income. There was no change to total noninterest income as previously reported as a result of these reclassifications.
