Use of Non-GAAP Financial Measures

The measures entitled average core deposits; average core deposits excluding average state, county, and municipal deposits; low-cost core deposits excluding the impact from the sale of deposits of the Memphis, Tennessee branches in January 2014; Tier 1 common equity ratio; tangible common equity to tangible assets ratio; adjusted earnings per diluted share; adjusted pre-tax, pre-credit costs income; and adjusted non-interest expense are not measures recognized under U.S. generally accepted accounting principles (GAAP) and therefore are considered non-GAAP financial measures. The most comparable GAAP measures are total average deposits; total deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense, respectively.

Synovus believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus’ capital strength and the performance of its core business. These non-GAAP financial measures should not be considered as substitutes for total average deposits; total deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense determined in accordance with GAAP and may not be comparable to other similarly titled measures at other companies.

The computations of average core deposits; average core deposits excluding average state, county, and municipal deposits; low-cost core deposits excluding the impact from the sale of deposits of the Memphis, Tennessee branches in January 2014; Tier 1 common equity ratio; tangible common equity to tangible assets ratio; adjusted earnings per diluted share; adjusted pre-tax, pre-credit costs income; and adjusted non-interest expense; and the reconciliation of these measures to total average deposits; total deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense are set forth in the tables below.
