Business Combinations [Abstract] |
Business Combinations | Note 2 – Business Combinations Somerville Bank & Trust Company Immediately following the close of business on December 31, 2013, Trustmark National Bank (TNB), a subsidiary of Trustmark, completed its merger with Somerville Bank & Trust Company (Somerville), also a subsidiary of Trustmark, with TNB as the surviving entity in the merger. Somerville, headquartered in Somerville, Tennessee, provided banking services in the eastern Memphis metropolitan statistical area through five offices. At December 31, 2013, Somerville had total assets of $219.6 million. TNB and Somerville were both wholly owned subsidiaries of Trustmark; as such, the merger represented a business reorganization between affiliates under common control. Oxford, Mississippi Branches On July 26, 2013, TNB completed its acquisition of two branches of SOUTHBank, F.S.B. (SOUTHBank), located in Oxford, Mississippi. As a result of this acquisition, TNB assumed deposit accounts of approximately $11.7 million in addition to purchasing the two physical branch offices. The transaction was not material to Trustmark’s consolidated financial statements and was not considered a business combination in accordance with FASB ASC Topic 805. BancTrust Financial Group, Inc. On February 15, 2013, Trustmark completed its merger with BancTrust Financial Group, Inc. (BancTrust), a 26-year-old bank holding company headquartered in Mobile, Alabama. In accordance with the terms of the definitive agreement, the holders of BancTrust common stock received 0.125 of a share of Trustmark common stock for each share of BancTrust common stock in a tax-free exchange. Trustmark issued approximately 2.24 million shares of its common stock for all issued and outstanding shares of BancTrust common stock. The total value of the 2.24 million shares of Trustmark common stock issued to the BancTrust shareholders on the merger date was approximately $53.5 million, based on a closing stock price of $23.83 per share of Trustmark common stock on February 15, 2013. At closing, Trustmark repurchased the $50.0 million of BancTrust preferred stock and associated warrant issued to the U.S. Department of Treasury under the Capital Purchase Program for approximately $52.6 million. The merger with BancTrust was consistent with Trustmark’s strategic plan to selectively expand the Trustmark franchise. The merger provided Trustmark entry into more than 15 markets in Alabama and enhanced the Trustmark franchise in the Florida Panhandle. This merger was accounted for under the acquisition method in accordance with FASB ASC Topic 805. Accordingly, the assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the merger date. Trustmark recorded fair value adjustments based on the estimated fair value of certain acquired loans, premises and equipment, net and other real estate. During 2013, these measurement period adjustments resulted in a decrease in acquired noncovered loans of $6.8 million, a decrease in premises and equipment, net of $627 thousand, a decrease in other real estate of $2.6 million, an increase in the deferred tax asset of $3.4 million and an increase in goodwill of $6.3 million. Trustmark also recorded an adjustment to transfer $1.6 million of acquired property from premises and equipment, net to other real estate during 2013. During the first quarter of 2014, Trustmark recorded an additional measurement period adjustment that resulted in a $7.4 million decrease in goodwill with a corresponding increase in the deferred tax asset. These measurement period adjustments were presented on a retrospective basis, consistent with applicable accounting guidance. The purchase price allocation was finalized during the first quarter of 2014. The statement of assets purchased and liabilities assumed in the BancTrust merger is presented below at their adjusted estimated fair values as of the merger date of February 15, 2013 ($ in thousands):
Assets: |  |  |

Loans held for sale |  |  | 1,050 |
Acquired noncovered loans |  |  | 944,235 |
Premises and equipment, net |  |  | 54,952 |
Identifiable intangible assets |  |  | 33,498 |
Other real estate |  |  | 40,103 |
Other assets |  |  | 109,423 |
Total Assets |  |  | 1,852,893 |
Liabilities: |  |  |  |

Net identified assets acquired at fair value |  |  | 31,827 |
Goodwill |  |  | 74,247 |
Net assets acquired at fair value |  | $ | 106,074 |
The excess of the consideration paid over the estimated fair value of the net assets acquired was $74.2 million, which was recorded as goodwill under FASB ASC Topic 805. The identifiable intangible assets acquired represent the core deposit intangible at fair value at the acquisition date. The core deposit intangible is being amortized on an accelerated basis over the estimated useful life, currently expected to be approximately 10 years. Loans, excluding LHFS, acquired from BancTrust were evaluated under a fair value process involving various degrees of deterioration in credit quality since origination, and also for those loans for which it was probable at acquisition that Trustmark would not be able to collect all contractually required payments. These loans, with the exception of revolving credit agreements and leases, are referred to as acquired impaired loans and are accounted for in accordance with FASB ASC Topic 310-30. Refer to Note 6 – Acquired Loans for further information on acquired loans. The operations of BancTrust are included in Trustmark’s operating results from February 15, 2013. Trustmark’s noninterest expense during the first quarter of 2013 included non-routine BancTrust transaction expenses totaling approximately $9.4 million (change in control and severance expense of $1.4 million included in salaries and benefits; professional fees, contract termination and other expenses of $7.9 million included in other expense). Bay Bank & Trust Company On March 16, 2012, Trustmark completed its merger with Bay Bank & Trust Co. (Bay Bank), a 76-year old financial institution headquartered in Panama City, Florida. Trustmark acquired all outstanding common stock of Bay Bank for approximately $22 million in cash and stock, comprised of $10 million in cash and the issuance of approximately 510 thousand shares of Trustmark common stock valued at $12 million. This merger was accounted for under the acquisition method in accordance with FASB ASC Topic 805. Accordingly, the assets and liabilities, both tangible and intangible, are recorded at their estimated fair values as of the merger date. The purchase price allocation was finalized in the second quarter of 2012. The statement of assets purchased and liabilities assumed in the Bay Bank merger is presented below at their estimated fair values as of the merger date of March 16, 2012 ($ in thousands):
Assets: |  |  |
Cash and due from banks |  | $ | 88,154 |
Securities available for sale |  |  | 26,369 |
Acquired noncovered loans |  |  | 97,914 |

Bargain purchase gain |  |  | 3,635 |
Income taxes |  |  | - |
Bargain purchase gain, net of taxes |  | $ | 3,635 |
The bargain purchase gain represents the excess of the net of the estimated fair value of the assets acquired and liabilities assumed over the consideration paid to Bay Bank. Initially, Trustmark recognized a bargain purchase gain of $2.8 million during the first quarter of 2012 and subsequently increased the bargain purchase gain by $881 thousand during the second quarter of 2012 as the fair values associated with the Bay Bank acquisition were finalized. The gain of $3.6 million recognized by Trustmark was considered a gain from a bargain purchase under FASB ASC Topic 805 and was included in other noninterest income for 2012. Included in noninterest expense for 2012 are non-routine Bay Bank transaction expenses totaling approximately $2.6 million (change in control and severance expense of $672 thousand included in salaries and benefits; contract termination and other expenses of $1.9 million included in other expense). The identifiable intangible assets represent the core deposit intangible at fair value at the acquisition date. The core deposit intangible is being amortized on an accelerated basis over the estimated useful life, currently expected to be approximately 10 years. Loans acquired from Bay Bank were evaluated under a fair value process involving various degrees of deterioration in credit quality since origination, and also for those loans for which it was probable at acquisition that Trustmark would not be able to collect all contractually required payments. These loans, with the exception of revolving credit agreements, are referred to as acquired impaired loans and are accounted for in accordance with FASB ASC Topic 310-30. Fair Value of Acquired Financial Instruments For financial instruments measured at fair value, Trustmark utilized Level 2 inputs to determine the fair value of securities available for sale, time deposits (included in deposits above) and FHLB advances (shown as other borrowings above). Level 3 inputs were used to determine the fair value of acquired loans, identifiable intangible assets and other real estate. The methodology and significant assumptions used in estimating the fair values of these financial assets and liabilities are as follows: Securities Available for Sale Estimated fair values for securities available for sale are based on quoted market prices where available. If quoted market prices are not available, estimated fair values are based on quoted market prices of comparable instruments. Acquired Loans Fair value of acquired loans is determined using a discounted cash flow model based on assumptions regarding the amount and timing of principal and interest payments, estimated prepayments, estimated default rates, estimated loss severity in the event of defaults and current market rates. Identifiable Intangible Assets The fair value assigned to the identifiable intangible assets, in this case core deposit intangibles, represent the future economic benefit of the potential cost savings from acquiring core deposits in the acquisition compared to the cost of obtaining alternative funding from market sources. Other Real Estate Other real estate was initially recorded at its estimated fair value on the acquisition date based on similar market comparable valuations less estimated selling costs. Time Deposits Time deposits were valued by projecting expected cash flows into the future based on each account’s contracted rate and then determining the present value of those expected cash flows using current rates for deposits with similar maturities. FHLB Advances FHLB advances were valued by projecting expected cash flows into the future based on each advance’s contracted rate and then determining the present value of those expected cash flows using current rates for advances with similar maturities. Please refer to Note 19 – Fair Value for more information on Trustmark’s classification of financial instruments based on valuation inputs within the fair value hierarchy.
