Heritage Banking Group

On April 15, 2011, the Mississippi Department of Banking and Consumer Finance closed the Heritage Banking Group (Heritage), a 90-year old financial institution headquartered in Carthage, Mississippi, and appointed the Federal Deposit Insurance Corporation (FDIC) as receiver.  On the same date, Trustmark National Bank (TNB) entered into a purchase and assumption agreement with the FDIC in which TNB agreed to assume all of the deposits and purchased essentially all of the assets of Heritage.  The FDIC and TNB entered into a loss-share transaction on approximately $151.9 million of Heritage assets, which covers substantially all loans and all other real estate. Under the loss-share agreement, the FDIC will cover 80% of covered loan and other real estate losses incurred.  Because of the loss protection provided by the FDIC, the risk characteristics of the Heritage loans and other real estate covered by the loss-share agreement are significantly different from those assets not covered by this agreement.  As a result, Trustmark will refer to loans and other real estate subject to the loss-share agreement as “covered” while loans and other real estate that are not subject to the loss-share agreement will be referred to as “excluding covered.”  The loss-share agreement applicable to single family residential mortgage loans and related foreclosed real estate provides for FDIC loss sharing and TNB's reimbursement to the FDIC for recoveries of covered losses for ten years from the date on which the loss-share agreement was entered. The loss-share agreement applicable to commercial loans and related foreclosed real estate provides for FDIC loss sharing for five years from the date on which the loss-share agreement was entered and TNB's reimbursement to the FDIC for recoveries of covered losses for an additional three years thereafter.

Pursuant to the provisions of the Heritage loss-share agreement, TNB may be required to make a true-up payment to the FDIC at the termination of the loss-share agreement should actual losses be less than certain thresholds established in the agreement.  To the extent that actual losses on covered loans and covered other real estate are less than estimated losses, the applicable true-up payable to the FDIC upon termination of the loss-share agreement will increase. To the extent that actual losses on covered loans and covered other real estate are more than estimated losses, the applicable true-up payable to the FDIC upon termination of the loss-share agreement will decrease.  TNB calculates the projected true-up payable to the FDIC quarterly and records a FDIC true-up provision for the present value of the projected true-up payable to the FDIC at the termination of the loss-share agreement.  The FDIC indemnification asset is presented net of the FDIC true-up provision.  Changes in the FDIC true-up provision are recorded to noninterest income.

The assets purchased and liabilities assumed for the Heritage acquisition have been accounted for under the acquisition method of accounting (formerly the purchase method). The assets and liabilities, both tangible and intangible, are recorded at their estimated fair values as of the acquisition date. The fair value amounts are subject to change for up to one year after the closing date as additional information relating to closing date fair values becomes available. The amounts are also subject to adjustments based upon final settlement with the FDIC.

The statement of assets purchased and liabilities assumed in the Heritage acquisition are presented below at their estimated fair values as of the acquisition date of April 15, 2011 ($ in thousands):

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 short-term borrowings above).  Level 3 inputs were used to determine the fair value of both LHFI and covered loans, identifiable intangible assets, covered other real estate and the FDIC indemnification asset.  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.

LHFI and Covered 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.

Covered Other Real Estate

Covered 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.

FDIC Indemnification Asset

The FDIC indemnification asset was initially recorded at fair value, based on the discounted value of expected future cash flows under the loss-share agreement.

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 account'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 18 – Fair Value for more information on Trustmark's classification of financial instruments based on valuation inputs within the fair value hierarchy.

The bargain purchase gain represents the net of the estimated fair value of the assets acquired and liabilities assumed and is influenced significantly by the FDIC-assisted transaction process.  Under the FDIC-assisted transaction process, only certain assets and liabilities are transferred to the acquirer and, depending on the nature and amount of the acquirer's bid, the FDIC may be required to make a cash payment to the acquirer.  The pretax gain of $7.5 million recognized by Trustmark is considered a bargain purchase transaction under FASB ASC Topic 805, “Business Combinations.”  The gain was recognized as other noninterest income in Trustmark's consolidated statements of income for the year ended December 31, 2011.

The operations of Heritage are included in Trustmark's operating results from April 15, 2011, and added revenue of $13.0 million and net income available to common shareholders of $6.5 million through December 31, 2011.  Such operating results are not necessarily indicative of future operating results.  Trustmark believes that given the nature of the assets and liabilities assumed, the significant amount of fair value adjustments and the FDIC loss sharing agreements now in place, historical results of Heritage are not meaningful to Trustmark's results of operations and thus no pro forma information is presented.

Bay Bank & Trust Company

On November 30, 2011, Trustmark announced the signing of a definitive agreement in which Bay Bank & Trust Co. (Bay Bank), a 76-year old financial institution headquartered in Panama City, Florida, will merge into TNB.  As of December 31, 2011, Bay Bank reported loans of $116.9 million and deposits of $206.6 million.  Under the terms of the definitive agreement, the transaction is valued at $22 million, with $10 million of the consideration to be paid in cash and $12 million to be paid in common stock of Trustmark.  The consideration represents approximately 86% of Bay Bank's tangible book value as of December 31, 2011.  The transaction, which is expected to be completed during the first quarter of 2012, is subject to approval by Bay Bank's shareholders.  On January 26, 2012, the OCC granted conditional approval, subject to customary requirements, of the merger of Bay Bank with and into TNB.
