Exhibit 99.3

Explanation of Non-GAAP Financial Measures

The measures entitled tangible common equity to tangible assets ratio, tangible common equity to risk-weighted assets ratio, core deposits, core deposits excluding time deposits, net interest margin excluding the negative impact of non-performing assets, pre-tax, pre-credit costs income, non-interest expense excluding credit costs and other non-recurring items, and fundamental 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 the ratio of total shareholders’ equity to total assets, total deposits, net interest margin, loss before income taxes, and total non-interest expense, respectively.

Management uses these non-GAAP measures to assess the performance of Synovus’ core business and its capital position. Synovus believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist 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 the ratio of total shareholders’ equity to total assets, total deposits, net interest margin, loss before income taxes, or total non-interest expense determined in accordance with GAAP and may not be comparable to other similarly titled measures at other companies. Total risk-weighted assets is a required measure used by banks and financial institutions in reporting regulatory capital and regulatory capital ratios to Federal and state regulatory agencies. The tangible common equity to tangible assets ratio and the tangible common equity to risk-weighted assets ratio are used by management and investment analysts to assess the strength of Synovus’ capital position. Core deposits and core deposits excluding time deposits are measures used by management to evaluate organic growth of deposits and the quality of deposits as a funding source. Net interest margin excluding the negative impact of non-performing assets is a measure used by management to measure net interest margin exclusive of the impact of non-performing assets and associated net interest charge-offs. Pre-tax, pre-credit costs income is a measure used by management to evaluate core operating results exclusive of credit costs as well as certain non-core expenses such as goodwill impairment charges, severance charges, net litigation contingency expense (recovery), and the gain on sale of Visa shares. Non-interest expense excluding credit costs and other non-recurring items is a measure used by management to evaluate core non-interest expense exclusive of other credit costs, severance charges, net litigation (expense) recovery, and goodwill impairment charges (i.e., excluding components of non-interest expense which are also excluded in the computation of pre-tax, pre-credit costs income). Fundamental non-interest expense is a measure used by management to evaluate core non-interest expense exclusive of other credit costs, severance charges, net litigation (expense) recovery, goodwill impairment charges, and FDIC insurance expense.

The computations of the tangible common equity to tangible assets ratio, the tangible common equity to risk-weighted assets ratio, core deposits, core deposits excluding time deposits, net interest margin excluding the negative impact of non-performing assets, pre-tax, pre-credit costs income, non-interest expense excluding credit costs and other non-recurring items, and fundamental non-interest expense, and the reconciliation of these measures to the ratio of total shareholders’ equity to total assets, total deposits, net interest margin, loss before income taxes, and total non-interest expense are set forth in the tables below:
