Significant Accounting Policies [Abstract]
Significant Accounting Policies	Business Operations The accompanying unaudited interim consolidated financial statements of Synovus include the accounts of the Parent Company and its consolidated subsidiaries. Synovus provides integrated financial services, including commercial and retail banking, financial management, insurance, and mortgage services to its customers through locally-branded divisions of its wholly-owned subsidiary bank, Synovus Bank, in offices located throughout Georgia, Alabama, South Carolina, Florida, and Tennessee. In addition to our banking operations, we also provide various other financial services to our customers through the following direct and indirect wholly-owned non-bank subsidiaries, including: Synovus Securities, Inc., headquartered in Columbus, Georgia, which specializes in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer and the provision of individual investment advice on equity and other securities; Synovus Trust Company, N.A., headquartered in Columbus, Georgia, which provides trust services; Synovus Mortgage Corp., headquartered in Birmingham, Alabama, which offers mortgage services; and GLOBALT, Inc., headquartered in Atlanta, Georgia, which provides asset management and financial planning services. Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income, and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2012 Form 10-K. There have been no significant changes to the accounting policies as disclosed in Synovus' 2012 Form 10-K. In preparing the unaudited interim consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses; the valuation of other real estate; the fair value of investment securities; the fair value of private equity investments; and the valuation of deferred tax assets. In connection with the determination of the allowance for loan losses and the valuation of certain impaired loans and other real estate, management obtains independent appraisals for significant properties and properties collateralizing impaired loans. In making this determination, management also considers other factors or recent developments, such as changes in absorption rates or market conditions at the time of valuation and anticipated sales values based on management’s plans for disposition. Cash and Cash Equivalents Cash and cash equivalents consist of cash and due from banks. At June 30, 2013 and December 31, 2012, cash and cash equivalents included $100.3 million and $68.4 million, respectively, on deposit to meet Federal Reserve Bank requirements. At June 30, 2013 and December 31, 2012, $15.4 million and $15.5 million, respectively, of the due from banks balance was restricted as to withdrawal, including $15.0 million at those dates on deposit pursuant to a payment network arrangement. Short-term Investments Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements. Interest earning deposits with banks include $12.7 million at June 30, 2013 and $14.2 million at December 31, 2012, which is pledged as collateral in connection with certain letters of credit. Federal funds sold include $84.6 million at June 30, 2013, and $110.0 million at December 31, 2012, which is pledged to collateralize certain derivative instruments. Federal funds sold and securities purchased under resale agreements, and Federal funds purchased and securities sold under repurchase agreements, generally mature in one day. Recently Adopted Accounting Standards Updates During 2013, Synovus adopted the provisions of the following ASUs: ASU 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. This ASU relates to testing intangibles other than goodwill for impairment, and was adopted on January 1, 2013. If certain conditions are met, the ASU provides for a qualitative impairment assessment instead of a quantitative assessment. For Synovus, the ASU primarily applies to core deposit intangibles, which have a current carrying value of only $3.0 million. The ASU did not have an impact on Synovus' unaudited interim consolidated financial statements. ASU 2011-11, Disclosures about Offsetting Assets and Liabilities and ASU 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 requires additional disclosures about financial instruments and derivative instruments that are offset or subject to an enforceable master netting arrangement or similar agreement. ASU 2013-01 clarifies that the disclosure requirements of ASU 2011-11 do not apply to trade receivables. The ASU also clarifies that the disclosure requirements in ASU 2011-11 apply to repurchase and reverse repurchase agreements, securities borrowing and lending agreements that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement, and derivatives accounted for in accordance with ASC 815-Derivatives and Hedging. At this time and January 1, 2013, the date of adoption, Synovus does not have any financial instruments that would be subject to the new requirements of ASU 2011-11; therefore, the ASU did not affect Synovus' unaudited interim consolidated financial statements. ASU 2013-02, Reporting of Amount Reclassified Out of Accumulated Other Comprehensive Income. The FASB issued this ASU to improve the transparency of reporting reclassifications out of accumulated other comprehensive income by requiring entities to present in one place information about significant amounts reclassified and, in some cases, to provide cross-references to related footnote disclosures. ASU 2013-02 does not amend existing requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 requires an entity to disaggregate the total change of each component of other comprehensive income and separately present reclassification adjustments and current period other comprehensive income. The provisions of ASU 2013-02 also require that entities present either in a single footnote or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line item affected by the reclassification. If a component is not required to be reclassified to net income in its entirety, entities would instead cross reference to the related footnote to the financial statements for additional information. Synovus adopted the provisions of ASU 2013-02 effective January 1, 2013. See "Note 9 - Other Comprehensive Income" to the unaudited interim consolidated financial statements for the disclosures required by ASU 2013-02. ASU 2013-10, Derivatives and Hedging (Topic 815): Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. This ASU permits the Fed Funds Effective Swap Rate (also referred to as the Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under FASB Topic 815, in addition to interest rates on direct Treasury obligations of the U.S. government and LIBOR. The amendments also remove the restriction on using different benchmark rates for similar hedges. The final guidance, issued on July 17, 2013, is effective immediately. Synovus will consider the provisions of this new guidance when developing new hedging strategies. Reclassifications Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation. Subsequent Events Synovus has evaluated for consideration, or disclosure, all transactions, events, and circumstances, subsequent to the date of the consolidated balance sheet and through the date the accompanying unaudited interim consolidated financial statements were issued, and has reflected, or disclosed, those items deemed appropriate within the unaudited interim consolidated financial statements and related footnotes, including Note 16 - Subsequent Events.
