Business, Basis of Financial Statement Presentation and Principles of Consolidation

Note 1 – Business, Basis of Financial Statement Presentation and Principles of Consolidation

Trustmark Corporation (Trustmark) is a multi-bank holding company headquartered in Jackson, Mississippi. Through its subsidiaries, Trustmark operates as a financial services organization providing banking and financial solutions to corporate institutions and individual customers through approximately 220 offices in Alabama, Florida, Mississippi, Tennessee and Texas.

The consolidated financial statements in this quarterly report on Form 10-Q include the accounts of Trustmark and all other entities in which Trustmark has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements, and notes thereto, included in Trustmark's 2012 annual report on Form 10-K.

Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. In the opinion of Management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of these consolidated financial statements have been included. The preparation of financial statements in conformity with these accounting principles requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and income and expense during the reporting period and the related disclosures. Although Management's estimates contemplate current conditions and how they are expected to change in the future, it is reasonably possible that in 2013 actual conditions could vary from those anticipated, which could affect our results of operations and financial condition. The allowance for loan losses, the amount and timing of expected cash flows from acquired loans and the Federal Deposit Insurance Corporation (FDIC) indemnification asset, the valuation of other real estate, the fair value of mortgage servicing rights, the valuation of goodwill and other identifiable intangibles, the status of contingencies and the fair values of financial instruments are particularly subject to change. Actual results could differ from those estimates.
