Reconciliation of Non-GAAP Disclosures 26 Operating Earnings Per Share The Company has provided supplemental performance measures on a tax-equivalent, tangible, operating, adjusted, or pre-tax pre-provision basis. These non-GAAP financial measures are supplements to GAAP, which are used to prepare the Company’s financial statements, and should not be considered in isolation or as substitutes for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance.

Reconciliation of Non-GAAP Disclosures 27 Operating Earnings Per Share Adjusted operating measures exclude the after-tax effect of merger and rebranding-related costs unrelated to the Company’s normal operations. In addition, adjusted operating measures now exclude the gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment) and gains or losses on sale of securities. The Company believes these non-GAAP adjusted measures provide investors with important information about the combined economic results of the organization’s operations Additionally, the Company believes that return on tangible common equity (ROTCE) is a meaningful supplement to GAAP financial measures and useful to investors because it measures the performance of a business consistently across time without regard to whether components of the business were acquired or developed internally.
