Notes to Consolidated Financial Statements

(Unaudited)

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 170 offices in 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 2011 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 2012 actual conditions could vary from those anticipated, which could affect our results of operations and financial condition. The allowance for loan losses, 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.

Note 2 – Business Combinations

Bay Bank & Trust Company

On March 16, 2012, Trustmark National Bank (TNB) 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 acquisition was accounted for under the acquisition method in accordance with FASB ASC Topic 805, “Business Combinations.” Accordingly, the assets and liabilities, both tangible and intangible, are recorded at their estimated fair values as of the acquisition date. The purchase price allocation is deemed preliminary as of March 31, 2012 and is expected to be finalized in the second quarter of 2012.

The statement of assets purchased and liabilities assumed in the Bay Bank acquisition is presented below at their estimated fair values as of the acquisition date of March 16, 2012 ($ in thousands):

Assets
Cash and due from banks	$	88,154
Securities available for sale		26,369
LHFI, excluding covered loans		98,053
Premises and equipment, net		9,466
Identifiable intangible assets		5,454
Other real estate		2,569
Other assets		4,014
Total Assets		234,079

Liabilities
Deposits		208,796
Other liabilities		526
Total Liabilities		209,322

Net assets acquired at fair value		24,757
Consideration paid to Bay Bank		22,003

Bargain purchase gain		2,754
Income taxes		-
Bargain purchase gain, net of taxes	$	2,754

The preliminary 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. The gain of $2.8 million recognized by Trustmark is considered a gain from a bargain purchase under FASB ASC Topic 805. The gain was recognized as other noninterest income in Trustmark’s consolidated statements of income for the three months ended March 31, 2012. Included in noninterest expense 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 TNB 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, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” Refer to Note 5 – Acquired Loans for further information on acquired loans.

The operations of Bay Bank are included in TNB’s operating results from March 16, 2012 and did not have a material impact on TNB’s results of operations. Therefore, pro forma information is not presented.

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, 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 “noncovered” or “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 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):

Assets
Cash and due from banks	$	50,447
Federal funds sold		1,000
Securities available for sale		6,389
LHFI, excluding covered loans		9,644
Covered loans		97,770
Premises and equipment, net		55
Identifiable intangible assets		902
Covered other real estate		7,485
FDIC indemnification asset		33,333
Other assets		218
Total Assets		207,243

Liabilities
Deposits		204,349
Short-term borrowings		23,157
Other liabilities		730
Total Liabilities		228,236

Net assets acquired at fair value		(20,993	)
Cash received on acquisition		28,449

Bargain purchase gain		7,456
Income taxes		2,852
Bargain purchase gain, net of taxes	$	4,604

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. The gain was recognized as other noninterest income in Trustmark’s consolidated statements of income for the year ended December 31, 2011. For the three months ended March 31, 2012, the operations of Heritage added revenue of $3.1 million and net income available to common shareholders of $1.7 million.

Fair Value of Acquired Financial Instruments

For financial instruments measured at fair value, TNB 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.

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, Including Covered Other Real Estate

Other real estate, including 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 16 – Fair Value for more information on Trustmark’s classification of financial instruments based on valuation inputs within the fair value hierarchy.

Note 3 – Securities Available for Sale and Held to Maturity

The following table is a summary of the amortized cost and estimated fair value of securities available for sale and held to maturity ($ in thousands):

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. In estimating other-than-temporary impairment losses, Management considers, among other things, the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer and the intent and ability of Trustmark to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. The unrealized losses shown above are primarily due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality. Because Trustmark does not intend to sell these securities and it is more likely than not that Trustmark will not be required to sell the investments before recovery of their amortized cost bases, which may be maturity, Trustmark does not consider these investments to be other-than-temporarily impaired at March 31, 2012. There were no other-than-temporary impairments for the three months ended March 31, 2012 and 2011.

Loan Concentrations

Trustmark does not have any loan concentrations other than those reflected in the preceding table, which exceed 10% of total loans. At March 31, 2012, Trustmark's geographic loan distribution was concentrated primarily in its Florida, Mississippi, Tennessee and Texas markets. A substantial portion of construction, land development and other land loans are secured by real estate in markets in which Trustmark is located. Accordingly, the ultimate collectability of a substantial portion of these loans and the recovery of a substantial portion of the carrying amount of other real estate owned, are susceptible to changes in market conditions in these areas.

Nonaccrual/Impaired Loans

At March 31, 2012 and December 31, 2011, the carrying amounts of nonaccrual LHFI which are considered for impairment analysis, were $105.8 million and $110.5 million, respectively. For collateral dependent loans, when a loan is deemed impaired, the full difference between the carrying amount of the loan and the most likely estimate of the asset’s fair value less cost to sell, is charged-off. All of Trustmark’s specifically evaluated impaired LHFI are collateral dependent loans. At March 31, 2012 and December 31, 2011, specifically evaluated impaired LHFI totaled $60.9 million and $68.9 million, respectively. In addition, these specifically evaluated impaired LHFI had a related allowance of $9.6 million and $8.8 million at the end of the respective periods. Specific charge-offs related to impaired LHFI totaled $1.4 million and $5.3 million. A recovery of $864 thousand was recorded to net income for these loans for the first three months of 2012, while provisions of $1.0 million were charged to net income for these loans for the first three months of 2011.

All commercial nonaccrual LHFI over $500 thousand are individually assessed for impairment. Impaired LHFI have been determined to be collateral dependent and assessed using a fair value approach. Fair value estimates begin with appraised values based on the current market value/as-is value of the property being appraised, normally from recently received and reviewed appraisals. If a current appraisal, or one with an inspection date within the past 12 months, using the necessary assumptions is not in the file, a new appraisal is ordered. Appraisals are obtained from State-certified Appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. The Appraisal Review Department has the authority to make adjustments to appraisals based on sales contracts, comparable sales and other pertinent information if an appraisal does not incorporate the effect of these assumptions. Appraised values are adjusted down for costs associated with asset disposal. Once the current appraisal is received and the estimated net realizable value determined, the value used in the impairment assessment is updated and adjustments are made to reflect further impairments. At the time a LHFI is deemed to be impaired, the full difference between book value and the most likely estimate of the asset’s net realizable value is charged off. However, as subsequent events dictate and estimated net realizable values decline, required reserves are established.

At March 31, 2012 and December 31, 2011, nonaccrual LHFI not specifically reviewed for impairment and written down to fair value less cost to sell, totaled $44.9 million and $41.6 million, respectively. In addition, these nonaccrual LHFI had allocated allowance for loan losses of $5.3 million and $3.9 million at the end of the respective periods. No material interest income was recognized in the income statement on impaired or nonaccrual loans for each of the periods ended March 31, 2012 and 2011.

The following table details LHFI individually and collectively evaluated for impairment at March 31, 2012 and December 31, 2011 ($ in thousands):

At March 31, 2012 and December 31, 2011, LHFI classified as troubled debt restructurings (TDRs) totaled $37.1 million and $34.2 million, respectively. For TDRs, Trustmark had a related loan loss allowance of $7.7 million and $4.5 million at the end of each respective period. Specific charge-offs related to TDRs totaled $563 thousand and $631 thousand for the three months ended March 31, 2012 and 2011, respectively. LHFI that are TDRs are charged down to the most likely fair value estimate less an estimated cost to sell for collateral dependent loans, which would approximate net realizable value.

The following table illustrates the impact of modifications classified as TDRs for the three months ended March 31, 2012 as well as those TDRs modified within the last 12 months for which there was a payment default during the period ($ in thousands):

	Three Months Ended March 31, 2012
Troubled Debt Restructurings	Number of Contracts		Pre-Modification Outstanding Recorded Investment		Post-Modification Outstanding Recorded Investment
Construction, land development and other land loans		8	$	3,611	$	3,611
Secured by 1-4 family residential properties		2		1,009		1,009
Secured by nonfarm, nonresidential properties		2		1,210		1,210

Construction, land development and other land loans		1	$	299
Secured by 1-4 family residential properties		3		1,382
Total		4	$	1,681

Trustmark’s TDRs have resulted primarily from allowing the borrower to pay interest only for an extended period of time rather than from forgiveness. Accordingly, as shown above, these TDRs have a similar recorded investment for both the pre-modification and post-modification disclosure. Trustmark has utilized loans 90 days or more past due to define payment default in determining TDRs that have subsequently defaulted.

Credit Quality Indicators

Trustmark’s loan portfolio credit quality indicators focus on six key quality ratios that are compared against bank tolerances. The loan indicators are total classified outstanding, total criticized outstanding, nonperforming loans, nonperforming assets, delinquencies and net loan losses. Due to the homogenous nature of consumer loans, Trustmark does not assign a formal internal risk rating to each credit and therefore the criticized and classified measures are unique to commercial loans.

In addition to monitoring portfolio credit quality indictors, Trustmark also measures how effectively the lending process is being managed and risks are being identified. As part of an ongoing monitoring process, Trustmark grades the commercial portfolio as it relates to financial statement exceptions, total policy exceptions, collateral exceptions and violations of law as shown below:

Financial Statement Exceptions – focuses on the officers’ ongoing efforts to obtain, evaluate and/or document sufficient information to determine the quality and status of the credits. This area includes the quality and condition of the files in terms of content, completeness and organization. Included is an evaluation of the systems/procedures used to insure compliance with policy such as financial statements, review memos and loan agreement covenants.

Underwriting/Policy – evaluates whether credits are adequately analyzed, appropriately structured and properly approved within requirements of bank loan policy. A properly approved credit is approved by adequate authority in a timely manner with all conditions of approval fulfilled. Total policy exceptions measure the level of exceptions to loan policy within a loan portfolio.

Collateral Documentation – focuses on the adequacy of documentation to support the obligation, perfect Trustmark’s collateral position and protect collateral value. There are two parts to this measure:

Collateral exceptions where certain collateral documentation is either not present, is not considered current or has expired.

90 days and over collateral exceptions are where certain collateral documentation is either not present, is not considered current or has expired and the exception has been identified in excess of 90 days.

Compliance with Law – focuses on underwriting, documentation, approval and reporting in compliance with banking laws and regulations. Primary emphasis is directed to Financial Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA) and Regulation O requirements.

Commercial Credits

Trustmark has established a Loan Grading System that consists of ten individual Credit Risk Grades (Risk Ratings) that encompass a range from loans where the expectation of loss is negligible to loans where loss has been established. The model is based on the risk of default for an individual credit and establishes certain criteria to delineate the level of risk across the ten unique Credit Risk Grades. Credit risk grade definitions are as follows:

Risk Rate (RR) 1 through RR 6 – Grades one through six represent groups of loans that are not subject to adverse criticism as defined in regulatory guidance. Loans in these groups exhibit characteristics that represent low to moderate risk measured by using a variety of credit risk criteria such as cash flow coverage, debt service coverage, balance sheet leverage, liquidity, management experience, industry position, prevailing economic conditions, support from secondary sources of repayment and other credit factors that may be relevant to a specific loan. In general, these loans are supported by properly margined collateral and guarantees of principal parties.

Other Assets Especially Mentioned (OAEM) (RR 7) – a loan that has a potential weakness that if not corrected will lead to a more severe rating. This rating is for credits that are currently protected but potentially weak because of an adverse feature or condition that if not corrected will lead to a further downgrade.

Substandard (RR 8) – a loan that has at least one identified weakness that is well defined. This rating is for credits where the primary sources of repayment are not viable at this time or where either the capital or collateral is not adequate to support the loan and the secondary means of repayment do not provide a sufficient level of support to offset the identified weakness but are sufficient to prevent a loss at this time. While these credits do not demonstrate any level of loss at this time, further deterioration would lead to a further downgrade.

Doubtful (RR 9) – a loan with an identified weakness that does not have a valid secondary source of repayment. Generally these credits have an impaired primary source of repayment and secondary sources are not sufficient to prevent a loss in the credit.

Loss (RR 10) – a loan or a portion of a loan that is deemed to be uncollectible.

By definition, credit risk grades OAEM (RR 7), substandard (RR 8), doubtful (RR 9) and loss (RR 10) are criticized loans while substandard (RR 8), doubtful (RR 9) and loss (RR 10) are classified loans. These definitions are standardized by all bank regulatory agencies and are generally equally applied to each individual lending institution. The remaining credit risk grades are considered pass credits and are solely defined by Trustmark.

The credit risk grades represent the probability of default (PD) for an individual credit and as such is not a direct indication of loss given default (LGD). The LGD aspect of the subject risk ratings is neither uniform across the nine primary commercial loan groups or constant between the geographic areas. To account for the variance in the LGD aspects of the risk rate system, the loss expectations for each risk rating is integrated into the allowance for loan loss methodology where the calculated LGD is allotted for each individual risk rating with respect to the individual loan group and unique geographic area. The LGD aspect of the reserve methodology is calculated each quarter as a component of the overall reserve factor for each risk grade by loan group and geographic area.

To enhance this process, loans of a certain size that are rated in one of the criticized categories are routinely reviewed to establish an expectation of loss, if any, and if such examination indicates that the level of reserve is not adequate to cover the expectation of loss, a special reserve or impairment is generally applied.

The distribution of the losses is accomplished by means of a loss distribution model that assigns a loss factor to each risk rating (1 to 9) in each commercial loan pool. A factor is not applied to risk rate 10 (Loss) as loans classified as Losses are not carried on the bank’s books over quarter ends as they are charged off within the period that the loss is determined.

The expected loss distribution is spread across the various risk ratings by the perceived level of risk for loss. The nine grade scale above ranges from a negligible risk of loss to an identified loss across its breadth. The loss distribution factors are graduated through the scale on a basis proportional to the degree of risk that appears manifest in each individual rating and assumes that migration through the loan grading system will occur.

Each loan officer assesses the appropriateness of the internal risk rating assigned to their credits on an ongoing basis. Trustmark’s Asset Review area conducts independent credit quality reviews of the majority of the bank’s commercial loan portfolio concentrations both on the underlying credit quality of each individual loan portfolio as well as the adherence to bank loan policy and the loan administration process. In general, Asset Review conducts reviews of each lending area within a six to eighteen month window depending on the overall credit quality results of the individual area.

In addition to the ongoing internal risk rate monitoring described above, Trustmark conducts monthly credit quality reviews (CQR) as well as semi-annual analysis and stress testing on all residential real estate development credits and non-owner occupied commercial real estate (CRE) credits of $1.0 million or more as described below:

Trustmark’s Credit Quality Review Committee meets monthly and performs the following functions: detailed review and evaluation of all loans of $100 thousand or more that are either delinquent thirty days or more or on nonaccrual, including determination of appropriate risk ratings, accrual status, and appropriate servicing officer; review of risk rate changes for relationships of $100 thousand or more; quarterly review of all nonaccruals less than $100 thousand to determine whether the credit should be charged off, returned to accrual, or remain in nonaccrual status; monthly/quarterly review of continuous action plans for all credits rated seven or worse for relationships of $100 thousand or more; monthly review of all commercial charge-offs of $25 thousand or more for the preceding month.

Residential real estate developments - a development project analysis is performed on all projects regardless of size. Performance of the development is assessed through an evaluation of the number of lots remaining, the payout ratios, and the loan-to-value ratios. Results are stress tested as to absorption and price of lots. This information is reviewed by each senior credit officer for that market to determine the need for any risk rate or accrual status changes.

Non-owner occupied commercial real estate – a cash flow analysis is performed on all projects with an outstanding balance of $1.0 million or more. In addition, credits are stress tested for vacancies and rate sensitivity. Confirmation is obtained that guarantor’s financial statements are current, taxes have been paid, and that there are no other issues that need to be addressed. This information is reviewed by each senior credit officer for that market to determine the need for any risk rate or accrual status changes.

Consumer Credits

Loans that do not meet a minimum custom credit score are reviewed quarterly by Management. The Retail Credit Review Committee reviews the volume and percentage of approvals that did not meet the minimum passing custom score by region, individual location, and officer. To assure that Trustmark continues to originate quality loans, this process allows Management to make necessary changes such as changes to underwriting procedures, credit policies, or changes in loan authority to Trustmark personnel.

Trustmark monitors the levels and severity of past due consumer loans on a daily basis through its collection activities. A detailed assessment of consumer loan delinquencies is performed monthly at both a product and market level by delivery channel, which incorporates the perceived level of risk at time of underwriting. Trustmark also monitors its consumer loan delinquency trends by comparing them to quarterly industry averages.

The allowance calculation methodology delineates the consumer loan portfolio into homogeneous pools of loans that contain similar structure, repayment, collateral and risk profile, which include residential mortgage, direct consumer loans, auto finance, credit cards, and overdrafts. For these pools, the historical loss experience is determined by calculating a 20-quarter rolling average and that loss factor is applied to each homogeneous pool to establish the quantitative aspect of the methodology. Where the loss experience does not fully cover the anticipated loss for a pool, an estimate is also applied to each homogeneous pool to establish the qualitative aspect of the methodology. The qualitative portion is the allocation of perceived risks across the loan portfolio to derive the potential losses that exist at the current point in time. This methodology utilizes five separate factors where each factor is made up of unique components that when weighted and combined produce an estimated level of reserve for each of the loan pools. The five factors include economic indicators, performance trends, management experience, lending policy measures, and credit concentrations.

The risk measure for each factor is converted to a scale ranging from 0 (No risk) to 100 (High Risk) to ensure that the combination of such factors is proportional. The determination of the risk measurement for each qualitative factor is done for all four markets combined. The resulting estimated reserve factor is then applied to each pool.

The resulting ratings from the individual factors are weighted and summed to establish the weighted average qualitative factor of a specific loan portfolio. This weighted average qualitative factor is then applied over the five loan pools.

Past Due LHFI

LHFI past due 90 days or more totaled $41.0 million and $43.6 million at March 31, 2012 and December 31, 2011, respectively. Included in these amounts are $39.5 million and $39.4 million, respectively, of serviced loans eligible for repurchase, which are fully guaranteed by GNMA. GNMA optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer's option and without GNMA's prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. This buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as loans held for sale, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as held for sale with the offsetting liability being reported as short-term borrowings. Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during the first three months of 2012 or 2011.

Allowance for Loan Losses, LHFI

Trustmark’s allowance for loan loss methodology for commercial loans is based upon regulatory guidance from its primary regulator and GAAP. The methodology delineates the commercial purpose and commercial construction loan portfolios into nine separate loan types (or pools), which had similar characteristics, such as, repayment, collateral and risk profiles. The nine basic loan pools are further segregated into Trustmark’s four key market regions, Florida, Mississippi, Tennessee and Texas, to take into consideration the uniqueness of each market. A 10-point risk rating system is utilized for each separate loan pool to apply a reserve factor consisting of quantitative and qualitative components to determine the needed allowance by each loan type. As a result, there are 360 risk rate factors for commercial loan types. The nine separate pools are segmented below:

Commercial Purpose Loans

Real Estate – Owner Occupied

Real Estate – Non-Owner Occupied

Working Capital

Non-Working Capital

Land

Lots and Development

Political Subdivisions

Commercial Construction Loans

1 to 4 Family

Non-1 to 4 Family

During the third quarter of 2011, Trustmark altered the quantitative factors of the allowance for loan loss methodology to reflect a twelve-quarter rolling average. The quantitative factors utilized in determining the required reserve are intended to reflect a twelve-quarter rolling average, one quarter in arrears, by loan type within each key market region, unless subsequent market factors suggests that a different method is called for. This alteration to Trustmark’s methodology allows for a greater sensitivity to current trends, such as economic changes as well as current loss profiles, which creates a more accurate depiction of historical losses. Prior to converting to a twelve-quarter rolling average, the quantitative factors reflected a three-year rolling average for Trustmark’s commercial loan book of business.

The qualitative factors are determined through the utilization of eight separate factors made up of unique characteristics that, when weighted and combined, produce an estimated level of reserve for each loan type. The qualitative factors considered are the following:

National and regional economic trends and conditions

Impact of recent performance trends

Experience, ability and effectiveness of management

Adherence to Trustmark’s loan policies, procedures and internal controls

Collateral, financial and underwriting exception trends

Credit concentrations

Acquisitions

Catastrophe

The measure for each qualitative factor is converted to a scale ranging from 0 (No risk) to 100 (High Risk), other than the last two factors, which are applied on a dollar-for-dollar basis, to ensure that the combination of such factors is proportional. The resulting ratings from the individual factors are weighted and summed to establish the weighted average qualitative factor of a specific loan portfolio within each key market region. This weighted-average qualitative factor is then distributed over the nine primary loan pools within each key market region based on the ranking by risk of each.

(1)	Acquired noncovered loans were included in LHFI at December 31, 2011.

The acquired loans were accounted for under the acquisition method of accounting.The acquired loans were recorded at their estimated fair value at the time of acquisition. 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. Estimated credit losses are included in the determination of fair value; therefore, an allowance for loan losses is not recorded on the acquisition date.

Loans acquired in an FDIC-assisted transaction and covered under loss-share agreements, such as those acquired from Heritage, are referred to as “covered loans” and are reported separately in Trustmark’s consolidated financial statements. The covered loans were recorded at their estimated fair value at the time of acquisition exclusive of the expected reimbursement cash flows from the FDIC.

TNB accounts for acquired impaired loans under FASB ASC Topic 310-30. An acquired loan is considered impaired when there is evidence of credit deterioration since origination and it is probable at the date of acquisition that TNB would be unable to collect all contractually required payments. Revolving credit agreements such as home equity lines are excluded from acquired impaired loan accounting requirements. TNB acquired $5.7 million and $3.8 million of revolving credit agreements, at fair value, in the Bay Bank and Heritage acquisitions, respectively, consisting mainly of home equity loans and commercial asset-based lines of credit, where the borrower had revolving privileges on the acquisition date. As such, TNB has accounted for such revolving loans in accordance with accounting requirements for acquired nonimpaired loans.

For acquired impaired loans, TNB (a) calculated the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (b) estimated the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). Under acquired impaired loan accounting, the difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the acquired impaired loan portfolio and such amount is subject to change over time based on the performance of such loans.

The excess of expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the “accretable yield” and is recorded as interest income over the estimated life of the loans using the effective yield method if the timing and amount of the future cash flows is reasonably estimable. Improvements in expected cash flows over those originally estimated increase the accretable yield and are recognized as interest income prospectively. Decreases in the amount and changes in the timing of expected cash flows compared to those originally estimated decrease the accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses. The carrying value of acquired impaired loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income.

TNB aggregates certain acquired loans into pools of loans with common credit risk characteristics such as loan type and risk rating. To establish accounting pools of acquired loans, loans are first categorized by similar purpose, similar collateral, similar geographic region, and by their operational servicing center. Within each category, loans are further segmented by ranges of risk determinants observed at the time of acquisition. For commercial loans, the primary risk determinant is the risk rating as assigned by TNB's internal credit officers. For consumer loans, the risk determinants include delinquency, FICO and loan to value. Statistical comparison of the pools reflect that each pool is comprised of loans generally of statistically similar characteristics, including loan type, loan risk and weighted average life. Each pool is then reviewed for statistical similarity of the pool constituents, including standard deviation of purchase price, weighted average life and concentration of the largest loans. Loan pools are initially booked at the aggregate fair value of the loan pool constituents, based on the present value of TNB's expected cash flows from the loans. An acquired loan will be removed from a pool of loans only if the loan is sold, foreclosed, or payment is received in full satisfaction of the loan. The acquired loan will be removed from the pool at its carrying value. If an individual acquired loan is removed from a pool of loans, the difference between its relative carrying amount and its cash, fair value of the collateral, or other assets received will be recognized as a gain or loss immediately in interest income on loans and would not affect the effective yield used to recognize the accretable yield on the remaining pool. Certain acquired loans are not pooled and are accounted for individually. Such loans consist of loans subject to accounting for acquired nonimpaired loans and loans that require more specific estimates of actual timing and amounts of cash flows due to the significant impairment of the borrower's ability to pay.

As required by FASB ASC Topic 310-30, TNB periodically re-estimates the expected cash flows to be collected over the life of the acquired impaired loans. If, based on current information and events, it is probable that TNB will be unable to collect all cash flows expected at acquisition plus additional cash flows expected to be collected arising from changes in estimate after acquisition, the acquired loans are considered impaired. The decrease in the expected cash flows reduces the carrying value of the acquired impaired loans as well as the accretable yield and results in a charge to income through the provision for loans losses and the establishment of an allowance for loan losses. If, based on current information and events, it is probable that there is a significant increase in the cash flows previously expected to be collected or if actual cash flows are significantly greater than cash flows previously expected, TNB will reduce any remaining allowance for loan losses established on the acquired impaired loans for the increase in the present value of cash flows expected to be collected. The increase in the expected cash flows for the acquired impaired loans over those originally estimated at acquisition increases the carrying value of the acquired impaired loans as well as the accretable yield. The increase in the accretable yield is recognized as interest income over the remaining average life of the acquired impaired loans.

On March 16, 2012, TNB completed its merger with Bay Bank. Loans acquired in the Bay Bank acquisition were evaluated for evidence of credit deterioration since origination and collectability of contractually required payments. TNB elected to account for all loans acquired in the Bay Bank acquisition as acquired impaired loans under FASB ASC Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality,” except for $5.7 million of acquired loans with revolving privileges, which are outside the scope of the guidance.

The following table presents the fair value of loans acquired as of the date of the Bay Bank acquisition ($ in thousands):

At acquisition date:	March 16, 2012
Contractually required principal and interest	$	134,961
Nonaccretable difference		19,852
Cash flows expected to be collected		115,109
Accretable yield		17,056
Fair value of loans at acquisition	$	98,053

On April 15, 2011, TNB entered into a purchase and assumption agreement with the FDIC in which TNB agreed to assume all of the deposits and essentially all of the assets of Heritage. Loans comprised the majority of the assets acquired and $97.8 million, or 91% of total loans acquired, are subject to the loss-share agreement with the FDIC whereby TNB is indemnified against a portion of the losses on covered loans and covered other real estate.

No allowance for loan losses was brought forward on any of the acquired loans as any credit deterioration evident in the loans was included in the determination of the fair value of the loans at the acquisition date. Updates to expected cash flows for acquired impaired loans accounted for under FASB ASC Topic 310-30 may result in a provision for loan losses and the establishment of an allowance for loan losses to the extent the amount and timing of expected cash flows decrease compared to those originally estimated at acquisition. TNB established an allowance for loan losses associated with covered acquired impaired loans during the fourth quarter of 2011 as a result of valuation procedures performed during the period.

The following table presents the components of the allowance for loan losses on acquired impaired loans for the three months ended March 31, 2012 ($ in thousands):

As discussed in Note 4 - Loans Held for Investment (LHFI) and Allowance for Loan Losses, LHFI TNB has established a Loan Grading System that consists of ten individual Credit Risk Grades (Risk Ratings) that encompass a range from loans where the expectation of loss is negligible to loans where loss has been established. The model is based on the risk of default for an individual credit and establishes certain criteria to delineate the level of risk across the ten unique Credit Risk Grades. These credit quality measures are unique to commercial loans. Credit quality for consumer loans is based on individual credit scores, aging status of the loan, and payment activity.

The tables below illustrate the carrying amount of acquired loans by credit quality indicator at March 31, 2012 and December 31, 2011 ($ in thousands):

(2) Acquired noncovered loans were included in LHFI at December 31, 2011.

Under FASB ASC Topic 310-30, acquired loans are generally considered accruing and performing loans as the loans accrete interest income over the estimated life of the loan when expected cash flows are reasonably estimable. Accordingly, acquired impaired loans that are contractually past due are still considered to be accruing and performing loans as long as the estimated cash flows are received as expected. If the timing and amount of cash flows is not reasonably estimable, the loans may be classified as nonaccrual loans and interest income may be recognized on a cash basis or as a reduction of the principal amount outstanding. At March 31, 2012, there were no acquired impaired loans accounted for under FASB ASC Topic 310-30 classified as nonaccrual loans. At March 31, 2012, approximately $561 thousand of acquired loans not accounted for under FASB ASC Topic 310-30 were classified as nonaccrual loans, compared to approximately $491 thousand of acquired loans at December 31, 2011.

Note 6 – Mortgage Banking

Trustmark recognizes as assets the rights to service mortgage loans based on the estimated fair value of the mortgage servicing rights (MSR) when loans are sold and the associated servicing rights are retained. Trustmark also incorporates a hedging strategy, which utilizes a portfolio of derivative instruments to achieve a return that would substantially offset the changes in fair value of MSR attributable to interest rates. Changes in the fair value of these derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by changes in the fair value of MSR.

The fair value of MSR is determined using discounted cash flow techniques benchmarked against third-party valuations. Estimates of fair value involve several assumptions, including the key valuation assumptions about market expectations of future prepayment rates, interest rates and discount rates which are provided by a third party firm. By way of example, an increase in either the prepayment speed or discount rate assumption will result in a decrease in the fair value of the MSR, while a decrease in either assumption will result in an increase in the fair value of the MSR. In recent years, there have been significant market-driven fluctuations in loan prepayment speeds and discount rates. These fluctuations can be rapid and may continue to be significant. Therefore, estimating prepayment speed and/or discount rates within ranges that market participants would use in determining the fair value of MSR requires significant management judgment.

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that offsets the changes in fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. Changes in the fair value of these exchange-traded derivative instruments, including administrative costs, are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of the MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative ineffectiveness of $1.0 million and a net positive ineffectiveness of $263 thousand for the three months ended March 31, 2012 and 2011, respectively.

See the section captioned “Noninterest Income” in Management’s Discussion and Analysis for further analysis of mortgage banking revenues, which includes the table for net hedge ineffectiveness.

The activity in MSR is detailed in the table below ($ in thousands):

	Three Months Ended March 31,
	2012			2011
Balance at beginning of period	$	43,274		$	51,151

Due to market changes		248			257
Due to runoff		(2,106	)		(1,290	)
Balance at end of period	$	45,893		$	53,598

Trustmark is subject to losses in its loan servicing portfolio due to loan foreclosures. For loans sold without recourse, Trustmark has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loans sold were in violation of representations or warranties made by Trustmark at the time of the sale, herein referred to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation and/or loans obtained through fraud by borrowers or other third parties such as appraisers. The total mortgage loan servicing putback expenses incurred by Trustmark during the first three months of 2012 and 2011 were $1.9 million and $643 thousand, respectively. At March 31, 2012 and December 31, 2011, accrued mortgage loan servicing putback expenses were $4.8 million and $4.3 million, respectively. There is inherent uncertainty in reasonably estimating the requirement for reserves against future mortgage loan servicing putback expenses. Future putback expenses are dependent on many subjective factors, including the review procedures of the purchasers and the potential refinance activity on loans sold with servicing released and the subsequent consequences under the representations and warranties.

Note 7 – Other Real Estate and Covered Other Real Estate

Other Real Estate, excluding Covered Other Real Estate

Other real estate owned, excluding covered other real estate, (noncovered other real estate owned) is recorded at the lower of cost or estimated fair value less the estimated cost of disposition. Fair value is based on independent appraisals and other relevant factors. Valuation adjustments required at foreclosure are charged to the allowance for loan losses. At March 31, 2012, Trustmark's geographic loan distribution was concentrated primarily in its Florida, Mississippi, Tennessee and Texas markets. The ultimate recovery of a substantial portion of the carrying amount of noncovered other real estate owned is susceptible to changes in market conditions in these areas.

For the periods presented, changes and gains (losses), net on noncovered other real estate were as follows ($ in thousands):

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. Any subsequent valuation adjustments due to declines in fair value are charged to noninterest expense, and are mostly offset by noninterest income representing the corresponding increase to the FDIC indemnification asset for the offsetting loss reimbursement amount. Any recoveries of previous valuation adjustments will be credited to noninterest expense with a corresponding charge to noninterest income for the portion of the recovery that is due to the FDIC.

As of the date of the Heritage acquisition, TNB acquired $7.5 million in covered other real estate. For the three months ended March 31, 2012, changes and gains, net on covered other real estate were as follows ($ in thousands):

Note 8 – 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. The difference between the present value at acquisition date and the undiscounted cash flows TNB expects to collect from the FDIC is accreted into noninterest income over the life of the FDIC indemnification asset. The FDIC indemnification asset is presented net of any true-up provision, pursuant to the provisions of the loss-share agreement, due to the FDIC at the termination of the loss-share agreement.

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. 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. TNB’s FDIC true-up provision totaled $661 thousand and $601 thousand at March 31, 2012 and December 31, 2011, respectively.

The FDIC indemnification asset is reduced as expected losses on covered loans and covered other real estate decline or as loss-share claims are submitted to the FDIC. The FDIC indemnification asset is revalued concurrent with the loan re-estimation and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of covered loans and covered other real estate. These adjustments are measured on the same basis as the related covered loans and covered other real estate. Any increases in cash flow of the covered loans and covered other real estate over those expected reduce the FDIC indemnification asset, and any decreases in cash flow of the covered loans and covered other real estate under those expected increase the FDIC indemnification asset. Increases and decreases to the FDIC indemnification asset are recorded as adjustments to noninterest income.

The following table presents changes in the FDIC indemnification asset for the periods presented ($ in thousands):

Note 10 – Defined Benefit and Other Postretirement Benefits

Capital Accumulation Plan

Trustmark maintains a noncontributory defined benefit pension plan (Trustmark Capital Accumulation Plan), which covers substantially all associates employed prior to January 1, 2007. The plan provides retirement benefits that are based on the length of credited service and final average compensation, as defined in the plan and vest upon three years of service. In an effort to control expenses, the Board voted to freeze plan benefits effective during 2009, with the exception of certain associates covered through plans obtained by acquisitions. Individuals will not earn additional benefits, except for interest as required by the IRS regulations, after the effective date. Associates will retain their previously earned pension benefits.

The following table presents information regarding the plan's net periodic benefit cost for the periods presented ($ in thousands):

	Three Months Ended March 31,
	2012			2011
Net periodic benefit cost
Service cost	$	140		$	137
Interest cost		945			1,115
Expected return on plan assets		(1,400	)		(1,471	)
Recognized net actuarial loss		1,309			1,037
Net periodic benefit cost	$	994		$	818

The acceptable range of contributions to the plan is determined each year by the plan's actuary. Trustmark's policy is to fund amounts allowable for federal income tax purposes. The actual amount of the contribution is determined based on the plan's funded status and return on plan assets as of the measurement date, which is December 31. For 2012, Trustmark’s minimum required contribution is expected to be $3.0 million. During 2011, Trustmark made a contribution of $1.0 million for the 2011 plan year.

Supplemental Retirement Plan

Trustmark maintains a nonqualified supplemental retirement plan covering directors who elected to defer fees, key executive officers and senior officers. The plan provides for defined death benefits and/or retirement benefits based on a participant's covered salary. Trustmark has acquired life insurance contracts on the participants covered under the plan, which may be used to fund future payments under the plan. The measurement date for the plan is December 31. The following table presents information regarding the plan's net periodic benefit cost for the periods presented ($ in thousands):

Note 11 – Stock and Incentive Compensation Plans

Trustmark has granted, and currently has outstanding, stock and incentive compensation awards subject to the provisions of the 1997 Long Term Incentive Plan (the 1997 Plan) and the 2005 Stock and Incentive Compensation Plan (the 2005 Plan). New awards have not been issued under the 1997 Plan since it was replaced by the 2005 Plan. The 2005 Plan is designed to provide flexibility to Trustmark regarding its ability to motivate, attract and retain the services of key associates and directors. The 2005 Plan allows Trustmark to make grants of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units and performance units to key associates and directors.

Stock Option Grants

Stock option awards under the 2005 Plan have been granted with an exercise price equal to the market price of Trustmark’s stock on the date of grant. Stock options granted under the 2005 Plan vest 20% per year and have a contractual term of seven years. Stock option awards, which were granted under the 1997 Plan, had an exercise price equal to the market price of Trustmark’s stock on the date of grant, vested equally over four years with a contractual ten-year term. During the second quarter of 2011, compensation expense related to stock options had been fully recognized. Compensation expense for stock options granted under these plans was estimated using the fair value of each option granted using the Black-Scholes option-pricing model and is recognized on the straight-line method over the requisite service period. No stock options have been granted since 2006, when Trustmark began granting restricted stock awards exclusively.

Restricted Stock Grants

Performance Awards

Trustmark’s performance awards are granted to Trustmark’s executive and senior management team. Performance awards granted vest based on performance goals of return on average tangible equity (ROATE) or return on average equity (ROAE) and total shareholder return (TSR) compared to a defined peer group. Awards based on TSR are valued utilizing a Monte Carlo simulation to estimate fair value of the awards at the grant date, while ROATE and ROAE awards are valued utilizing the fair value of Trustmark’s stock at the grant date based on the estimated number of shares expected to vest. The restriction period for performance awards covers a three-year vesting period. These awards are recognized on the straight-line method over the requisite service period. These awards provide for excess shares, if performance measures exceed 100%. Any excess shares granted are restricted for an additional three-year vesting period. The restricted share agreement provides for voting rights and dividend privileges.

Time-Vested Awards

Trustmark’s time-vested awards are granted to Trustmark’s executive and senior management team in both employee recruitment and retention. These awards are also granted to Trustmark’s Board of Directors and are restricted for thirty-six months from the award dates. Time-vested awards are valued utilizing the fair value of Trustmark’s stock at the grant date. These awards are recognized on the straight-line method over the requisite service period.

Performance-Based Restricted Stock Unit Award

During 2009, Trustmark’s previous Chairman and CEO was granted a cash-settled performance-based restricted stock unit award (the RSU award) with each unit having the value of one share of Trustmark’s common stock. The performance period covered a two-year period. This award was granted in connection with an employment agreement dated November 20, 2008, that provides for in lieu of receiving an equity compensation award in 2010 or 2011, the 2009 equity compensation award to be twice the amount of a normal award, with one-half of the award being performance-based and one-half service-based. The RSU award was granted outside of the 2005 Plan in lieu of granting shares of performance-based restricted stock that would exceed the annual limit permitted to be granted under the 2005 Plan, in order to satisfy the equity compensation provisions of the employment agreement. This award provided for excess shares, if performance goals of ROATE and TSR exceeded 100%. Both the performance awards and excess shares vested during the second quarter of 2011. Compensation expense for the RSU award was based on the approximate fair value of Trustmark’s stock at the end of each of the reporting periods and was finalized on the vesting date at a share price of $23.65.

The following tables summarize the stock and incentive plan activity for the period presented:

Note 12 – Contingencies

Lending Related

Letters of credit are conditional commitments issued by Trustmark to insure the performance of a customer to a third party. Trustmark issues financial and performance standby letters of credit in the normal course of business in order to fulfill the financing needs of its customers. A financial standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to repay an outstanding loan or debt instrument. A performance standby letter of credit irrevocably obligates Trustmark to pay a third-party beneficiary when a customer fails to perform some contractual, nonfinancial obligation. When issuing letters of credit, Trustmark uses essentially the same policies regarding credit risk and collateral, which are followed in the lending process. At March 31, 2012 and 2011, Trustmark’s maximum exposure to credit loss in the event of nonperformance by the other party for letters of credit was $161.7 million and $178.2 million, respectively. These amounts consist primarily of commitments with maturities of less than three years, which have an immaterial carrying value. Trustmark holds collateral to support standby letters of credit when deemed necessary. As of March 31, 2012, the fair value of collateral held was $52.0 million.

Legal Proceedings

Trustmark’s wholly-owned subsidiary, TNB, has been named as a defendant in two lawsuits related to the collapse of the Stanford Financial Group. The first is a purported class action complaint that was filed on August 23, 2009 in the District Court of Harris County, Texas, by Peggy Roif Rotstain, Guthrie Abbott, Catherine Burnell, Steven Queyrouze, Jaime Alexis Arroyo Bornstein and Juan C. Olano, on behalf of themselves and all others similarly situated, naming TNB and four other financial institutions unaffiliated with the Company as defendants. The complaint seeks to recover (i) alleged fraudulent transfers from each of the defendants in the amount of fees and other monies received by each defendant from entities controlled by R. Allen Stanford (collectively, the “Stanford Financial Group”) and (ii) damages allegedly attributable to alleged conspiracies by one or more of the defendants with the Stanford Financial Group to commit fraud and/or aid and abet fraud on the asserted grounds that defendants knew or should have known the Stanford Financial Group was conducting an illegal and fraudulent scheme. Plaintiffs have demanded a jury trial. Plaintiffs did not quantify damages. In November 2009, the lawsuit was removed to federal court by certain defendants and then transferred by the United States Panel on Multidistrict Litigation to federal court in the Northern District of Texas (Dallas) where multiple Stanford related matters are being consolidated for pre-trial proceedings. In May 2010, all defendants (including TNB) filed motions to dismiss the lawsuit, and the motions to dismiss have been fully briefed by all parties. The court has not yet ruled on the defendants’ motions to dismiss. In August 2010, the court authorized and approved the formation of an Official Stanford Investors Committee to represent the interests of Stanford investors and, under certain circumstances, to file legal actions for the benefit of Stanford investors. In December 2011, the Official Stanford Investors Committee filed a motion to intervene in this action. In January 2012, Plaintiffs filed a motion to join the Official Stanford Investors Committee as an additional plaintiff in this action. Trustmark opposed these two motions. The court has not yet ruled on the intervention and joinder motions.

The second Stanford-related lawsuit was filed on December 14, 2009 in the District Court of Ascension Parish, Louisiana, individually by Harold Jackson, Paul Blaine, Carolyn Bass Smith, Christine Nichols, and Ronald and Ramona Hebert naming TNB (misnamed as Trust National Bank) and other individuals and entities not affiliated with the Company as defendants. The complaint seeks to recover the money lost by these individual plaintiffs as a result of the collapse of the Stanford Financial Group (in addition to other damages) under various theories and causes of action, including negligence, breach of contract, breach of fiduciary duty, negligent misrepresentation, detrimental reliance, conspiracy, and violation of Louisiana’s uniform fiduciary, securities, and racketeering laws. The complaint does not quantify the amount of money the plaintiffs seek to recover. In January 2010, the lawsuit was removed to federal court by certain defendants and then transferred by the United States Panel on Multidistrict Litigation to federal court in the Northern District of Texas (Dallas) where multiple Stanford related matters are being consolidated for pre-trial proceedings. On March 29, 2010, the court stayed the case. TNB filed a motion to lift the stay, which was denied on February 28, 2012.

TNB’s relationship with the Stanford Financial Group began as a result of Trustmark’s acquisition of a Houston-based bank in August 2006, and consisted of correspondent banking and other traditional banking services in the ordinary course of business. Both Stanford-related lawsuits are in their preliminary stages and have been previously reported in the press and disclosed by Trustmark.

On December 2, 2011, TNB was sued in a putative class action lawsuit filed by plaintiff Kathy D. White, on behalf of herself and purportedly on behalf of all similarly situated customers of TNB, in the United States District Court for the Northern District of Mississippi, Greenville Division. The case was transferred to the United States District Court for the Southern District of Mississippi, Jackson Division, at the request of TNB; the pleadings are a matter of public record in that court's files, civil action 3:12 cv 00082 TSL MTP. The complaint challenged TNB’s practices regarding "overdraft" or "non-sufficient funds" fees charged by TNB in connection with customer use of debit cards, including TNB’s order of processing transactions, notices of charges, and calculations of fees. The complaint asserted claims of breach of contract, breach of a duty of good faith and fair dealing, unconscionability, conversion, and unjust enrichment. The plaintiff sought monetary damages, restitution, and injunctive and declaratory relief from TNB. Among other relief, plaintiff’s complaint demanded reimbursement of fees collected by TNB and seeks a prohibition against various means of calculating and collecting such fees in the future. On April 11, 2012, TNB filed a motion to dismiss the action, asserting the federal court lacked subject-matter jurisdiction. Plaintiff agreed to dismiss the case, and on April 27, 2012, the parties filed a Stipulation of Dismissal, ending the lawsuit. The case was dismissed "without prejudice" and without resolving the claims and defenses on their merits. Therefore, a similar action could be filed in the future.

Trustmark and its subsidiaries are also parties to other lawsuits and other claims that arise in the ordinary course of business. Some of the lawsuits assert claims related to the lending, collection, servicing, investment, trust and other business activities, and some of the lawsuits allege substantial claims for damages.

All pending legal proceedings described above are being vigorously contested. In the regular course of business, Management evaluates estimated losses or costs related to litigation, and provision is made for anticipated losses whenever Management believes that such losses are probable and can be reasonably estimated. At the present time, Management believes, based on the advice of legal counsel and Management’s evaluation, that (i) the final resolution of pending legal proceedings described above will not, individually or in the aggregate, have a material impact on Trustmark’s consolidated financial position or results of operations and (ii) a material adverse outcome in any such case is not reasonably possible.

Note 13 – Earnings Per Share

Basic earnings per share (EPS) is computed by dividing net income by the weighted-average shares of common stock outstanding. Diluted EPS is computed by dividing net income by the weighted-average shares of common stock outstanding, adjusted for the effect of potentially dilutive stock awards outstanding during the period. The following table reflects weighted-average shares used to calculate basic and diluted EPS for the periods presented (in thousands):

	Three Months Ended March 31,

Note 15 – Shareholders' Equity

Trustmark and TNB are subject to minimum capital requirements, which are administered by various federal regulatory agencies. These capital requirements, as defined by federal guidelines, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional, discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements of Trustmark and TNB. As of March 31, 2012, Trustmark and TNB have exceeded all of the minimum capital standards for the parent company and its primary banking subsidiary as established by regulatory requirements. In addition, TNB has met applicable regulatory guidelines to be considered well-capitalized at March 31, 2012. To be categorized in this manner, TNB must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the accompanying table. There are no significant conditions or events that have occurred since March 31, 2012, which Management believes have affected TNB's present classification.

Trustmark's and TNB's actual regulatory capital amounts and ratios are presented in the table below ($ in thousands):

Note 16 – Fair Value

Fair Value Measurements

FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and requires certain disclosures about fair value measurements. The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. Depending on the nature of the asset or liability, Trustmark uses various valuation techniques and assumptions when estimating fair value. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

Level 1 Inputs – Valuation is based upon quoted prices (unadjusted) in active markets for identical assets or liabilities that Trustmark has the ability to access at the measurement date.

Level 2 Inputs – Valuation is based upon quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability such as interest rates, yield curves, volatilities and default rates and inputs that are derived principally from or corroborated by observable market data.

Level 3 Inputs – Unobservable inputs reflecting the reporting entity’s own determination about the assumptions that market participants would use in pricing the asset or liability based on the best information available.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety is classified is based on the lowest level input that is significant to the fair value measurement in its entirety. Trustmark’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Financial Instruments Measured at Fair Value

The methodologies Trustmark uses in determining the fair values are based primarily on the use of independent, market-based data to reflect a value that would be reasonably expected upon exchange of the position in an orderly transaction between market participants at the measurement date. The large majority of assets that are stated at fair value are of a nature that can be valued using prices or inputs that are readily observable through a variety of independent data providers. The providers selected by Trustmark for fair valuation data are widely recognized and accepted vendors whose evaluations support the pricing functions of financial institutions, investment and mutual funds, and portfolio managers. Trustmark has documented and evaluated the pricing methodologies used by the vendors and maintains internal processes that regularly test valuations for anomalies.

Trustmark utilizes an independent pricing service to advise it on the carrying value of the securities available for sale portfolio. As part of Trustmark’s procedures, the price provided from the service is evaluated for reasonableness given market changes. When a questionable price exists, Trustmark investigates further to determine if the price is valid. If needed, other market participants may be utilized to determine the correct fair value. Trustmark has also reviewed and confirmed its determinations in thorough discussions with the pricing source regarding their methods of price discovery.

Mortgage loan commitments are valued based on the securities prices of similar collateral, term, rate and delivery for which the loan is eligible to deliver in place of the particular security. Trustmark acquires a broad array of mortgage security prices that are supplied by a market data vendor, which in turn accumulates prices from a broad list of securities dealers. Prices are processed through a mortgage pipeline management system that accumulates and segregates all loan commitment and forward-sale transactions according to the similarity of various characteristics (maturity, term, rate, and collateral). Prices are matched to those positions that are deemed to be an eligible substitute or offset (i.e., “deliverable”) for a corresponding security observed in the market place.

Trustmark estimates fair value of MSR through the use of prevailing market participant assumptions and market participant valuation processes. This valuation is periodically tested and validated against other third-party firm valuations.

Trustmark obtains the fair value of interest rate swaps from a third-party pricing service that uses an industry standard discounted cash flow methodology. In addition, credit valuation adjustments are incorporated in the fair values to account for potential nonperformance risk. In adjusting the fair value of its interest rate swap contracts for the effect of nonperformance risk, Trustmark has considered any applicable credit enhancements such as collateral postings, thresholds, mutual puts, and guarantees.

Trustmark has determined that the majority of the inputs used to value its interest rate swaps offered to qualified commercial borrowers fall within Level 2 of the fair value hierarchy, while the credit valuation adjustments associated with these derivatives utilize Level 3 inputs, such as estimates of current credit spreads. Trustmark has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of these derivative positions and has determined that the credit valuation adjustment is not significant to the overall valuation of these derivatives. As a result, Trustmark classifies its interest rate swap valuations in Level 2 of the fair value hierarchy.

Trustmark also utilizes derivative instruments such as Treasury note futures contracts and option contracts to achieve a fair value return that offsets the changes in fair value of MSR attributable to interest rates. These derivative instruments are exchange-traded and provide inputs, which allow them to be classified within Level 1 of the fair value hierarchy. In addition, Trustmark utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area which lack observable inputs for valuation purposes resulting in their inclusion in Level 3 of the fair value hierarchy.

At this time, Trustmark presents no fair values that are derived through internal modeling. Should positions requiring fair valuation arise that are not relevant to existing methodologies, Trustmark will make every reasonable effort to obtain market participant assumptions, or independent evaluation.

Financial Assets and Liabilities

Trustmark may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with U.S. GAAP. Assets at March 31, 2012, which have been measured at fair value on a nonrecurring basis, include impaired LHFI, excluding acquired loans. Loans for which it is probable Trustmark will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement are considered impaired. Impaired LHFI have been determined to be collateral dependent and assessed using a fair value approach. Specific allowances for impaired LHFI are based on comparisons of the recorded carrying values of the loans to the present value of the estimated cash flows of these loans at each loan’s original effective interest rate, the fair value of the collateral or the observable market prices of the loans. Fair value estimates begin with appraised values based on the current market value/as-is value of the property being appraised, normally from recently received and reviewed appraisals. Appraisals are obtained from State-certified Appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. The Appraisal Review Department has the authority to make adjustments to appraisals based on sales contracts, comparable sales and other pertinent information if an appraisal does not incorporate the effect of these assumptions. Appraised values are adjusted down for costs associated with asset disposal. At March 31, 2012, Trustmark had outstanding balances of $60.9 million in impaired LHFI that were specifically identified for evaluation and written down to fair value of the underlying collateral less cost to sell based on the fair value of the collateral or other unobservable input compared with $68.9 million at December 31, 2011. These impaired loans are classified as Level 3 in the fair value hierarchy. Impaired loans are periodically reviewed and evaluated for additional impairment and adjusted accordingly based on the same factors identified above.

Nonfinancial Assets and Liabilities

Certain nonfinancial assets measured at fair value on a nonrecurring basis include foreclosed assets (upon initial recognition or subsequent impairment), nonfinancial assets and nonfinancial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other nonfinancial long-lived assets measured at fair value for impairment assessment.

Other real estate owned, excluding covered other real estate, (noncovered other real estate owned) includes assets that have been acquired in satisfaction of debt through foreclosure and is recorded at the lower of cost or estimated fair value less the estimated cost of disposition. Fair value is based on independent appraisals and other relevant factors. In the determination of fair value subsequent to foreclosure, Management also considers other factors or recent developments, such as changes in market conditions from the time of valuation and anticipated sales values considering plans for disposition, which could result in an adjustment to lower the collateral value estimates indicated in the appraisals. At March 31, 2012, Trustmark's geographic loan distribution was concentrated primarily in its Florida, Mississippi, Tennessee and Texas markets. The ultimate recovery of a substantial portion of the carrying amount of noncovered other real estate owned is susceptible to changes in market conditions in these areas. Periodic revaluations are classified as Level 3 in the fair value hierarchy since assumptions are used that may not be observable in the market.

Certain foreclosed assets, upon initial recognition, are remeasured and reported at fair value through a charge-off to the allowance for loan losses based upon the fair value of the foreclosed asset. The fair value of a foreclosed asset, upon initial recognition, is estimated using Level 3 inputs based on adjusted observable market data. Foreclosed assets measured at fair value upon initial recognition totaled $8.9 million (utilizing Level 3 valuation inputs) during the three months ended March 31, 2012, compared with $19.6 million for the same period in 2011. In connection with the measurement and initial recognition of the foregoing foreclosed assets, Trustmark recognized charge-offs of the allowance for loan losses totaling $392 thousand and $1.8 million for the first three months of 2012 and 2011, respectively. Other than foreclosed assets measured at fair value upon initial recognition, $13.2 million of foreclosed assets were remeasured during the first three months of 2012, requiring write-downs of $2.4 million to reach their current fair values compared to $8.7 million of foreclosed assets that were remeasured during the first three months of 2011, requiring write-downs of $2.0 million.

Fair Value of Financial Instruments

FASB ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. A detailed description of the valuation methodologies used in estimating the fair value of financial instruments can be found in Note 18 included in Item 8 of Trustmark’s Form 10-K Annual Report for the year ended December 31, 2011.

The carrying amounts and estimated fair values of financial instruments at March 31, 2012 and December 31, 2011, are as follows ($ in thousands):

	March 31, 2012				December 31, 2011
	Carrying		Estimated		Carrying		Estimated
	Value		Fair Value		Value		Fair Value
Financial Assets:
Level 2 Inputs:
Cash and short-term investments	$	219,801	$	219,801	$	211,883	$	211,883

Junior subordinated debt securities		61,856		37,114		61,856		35,876

In cases where quoted market prices are not available, fair values are generally based on estimates using present value techniques. Trustmark’s premise in present value techniques is to represent the fair values on a basis of replacement value of the existing instrument given observed market rates on the measurement date. These techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates for those assets or liabilities cannot be necessarily substantiated by comparison to independent markets and, in many cases, may not be realizable in immediate settlement of the instruments. The estimated fair value of financial instruments with immediate and shorter-term maturities (generally 90 days or less) is assumed to be the same as the recorded book value. All nonfinancial instruments, by definition, have been excluded from these disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of Trustmark.

The fair values of net loans are estimated for portfolios of loans with similar financial characteristics. For variable rate loans that reprice frequently with no significant change in credit risk, fair values are based on carrying values. The fair values of certain mortgage loans, such as 1-4 family residential properties, are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. The fair values of other types of loans are estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The processes for estimating the fair value of net loans described above does not represent an exit price under FASB ASC Topic 820 and such an exit price could potentially produce a significantly different fair value estimate at March 31, 2012 and December 31, 2011.

Note 17 – Derivative Financial Instruments

Trustmark maintains an overall interest rate risk management strategy that incorporates the use of derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. Trustmark’s interest rate risk management strategy involves modifying the repricing characteristics of certain assets and liabilities so that changes in interest rates do not adversely affect the net interest margin and cash flows. Under the guidelines of FASB ASC Topic 815, “Derivatives and Hedging,” all derivative instruments are required to be recognized as either assets or liabilities and be carried at fair value on the balance sheet. The fair value of derivative positions outstanding is included in other assets and/or other liabilities in the accompanying consolidated balance sheets and in the net change in these financial statement line items in the accompanying consolidated statements of cash flows as well as included in noninterest income in the accompanying consolidated statements of income.

Derivatives Designated as Hedging Instruments

As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. These derivative instruments are designated as fair value hedges under FASB ASC Topic 815. The ineffective portion of changes in the fair value of the forward contracts and changes in the fair value of the loans designated as loans held for sale are recorded in noninterest income in mortgage banking, net. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $272.0 million at March 31, 2012, with a positive valuation adjustment of $176 thousand, compared to $199.5 million, with a negative valuation adjustment of $2.2 million as of December 31, 2011.

Derivatives not Designated as Hedging Instruments

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that offsets the changes in fair value of MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. Changes in the fair value of these exchange-traded derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by changes in the fair value of MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative ineffectiveness of $1.0 million and a net positive ineffectiveness of $263 thousand for the three months ended March 31, 2012 and 2011, respectively.

Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $169.7 million at March 31, 2012, with a positive valuation adjustment of $502 thousand, compared to $117.5 million, with a positive valuation adjustment of $702 thousand as of December 31, 2011.

Trustmark offers certain derivatives products such as interest rate swaps directly to qualified commercial borrowers seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial borrowers by entering into offsetting interest rate swap transactions with third parties. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded in noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, the changes in fair value substantially offset. In conjunction with the FASB’s fair value measurement guidance, Trustmark made an accounting policy election to measure the credit risk of these derivative financial instruments, which are subject to master netting agreements, on a net basis by counterparty portfolio. As of March 31, 2012, Trustmark had interest rate swaps with an aggregate notional amount of $94.4 million related to this program, compared to $71.2 million as of December 31, 2011. The fair value of these derivatives was immaterial at March 31, 2012 and December 31, 2011.

Trustmark has agreements with each of its interest rate swap counterparties that contain a provision where if Trustmark defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Trustmark could also be declared in default on its derivative obligations.

As of March 31, 2012, the termination value of interest rate swaps in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $1.7 million compared to $1.8 million as of December 31, 2011. As of March 31, 2012, Trustmark has not posted collateral against its obligations because of negotiated thresholds and minimum transfer amounts under these agreements. If Trustmark had breached any of these triggering provisions at March 31, 2012, it could have been required to settle its obligations under the agreements at the termination value.

Note 18 – Segment Information

Trustmark’s management reporting structure includes three segments: General Banking, Wealth Management and Insurance. General Banking is primarily responsible for all traditional banking products and services, including loans and deposits. General Banking also consists of internal operations such as Human Resources, Executive Administration, Treasury, Funds Management, Public Affairs and Corporate Finance. Wealth Management provides customized solutions for affluent customers by integrating financial services with traditional banking products and services such as private banking, money management, full-service brokerage, financial planning, personal and institutional trust and retirement services. Through Fisher Brown Bottrell Insurance, Inc. (FBBI), a wholly owned subsidiary of TNB, Trustmark’s Insurance Division provides a full range of retail insurance products including commercial risk management products, bonding, group benefits and personal lines coverage.

The accounting policies of each reportable segment are the same as those of Trustmark except for its internal allocations. Noninterest expenses for back-office operations support are allocated to segments based on estimated uses of those services. Trustmark measures the net interest income of its business segments with a process that assigns cost of funds or earnings credit on a matched-term basis. This process, called "funds transfer pricing," charges an appropriate cost of funds to assets held by a business unit, or credits the business unit for potential earnings for carrying liabilities. The net of these charges and credits flows through to the General Banking segment, which contains the management team responsible for determining the bank's funding and interest rate risk strategies.

The following table discloses financial information by reportable segment for the periods presented ($ in thousands).

Accounting Policies Recently Adopted and Pending Accounting Pronouncements

ASU 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-12 defers the effective date of the requirement of ASU 2011-05 to present separate line items on the income statement for reclassification adjustments of items out of accumulated other comprehensive income into net income. ASU 2011-12 was issued to allow the FASB time to redeliberate whether to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. Entities are still required to present reclassification adjustments within other comprehensive income either on the face of the statement that reports other comprehensive income or in the notes to the financial statements. All other requirements of ASU 2011-05 are not affected by ASU 2011-12. The requirements of ASU 2011-05, as amended by ASU 2011-12, became effective for Trustmark’s financial statements beginning January 1, 2012. For Trustmark, the impact of the ASU is a change in presentation only and did not have a significant impact on Trustmark’s consolidated financial statements.

ASU 2011-08, “Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment.” Issued in September 2011, ASU 2011-08 amends the guidance in ASC 350-202 on testing goodwill for impairment. Under the revised guidance, entities testing goodwill for impairment have the option of performing a qualitative assessment before calculating the fair value of the reporting unit (i.e., step 1 of the goodwill impairment test). If entities determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. The ASU does not change how goodwill is calculated or assigned to reporting units, nor does it revise the requirement to test goodwill annually for impairment. In addition, the ASU does not amend the requirement to test goodwill for impairment between annual tests if events or circumstances warrant; however, it does revise the examples of events and circumstances that an entity should consider. The amendments became effective for Trustmark’s annual goodwill impairment tests beginning January 1, 2012. The adoption of ASU 2011-08 did not have an impact on Trustmark’s consolidated financial statements.

ASU 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income.” ASU 2011-05 amends the FASB Accounting Standards Codification (Codification) to allow an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments to the Codification in the ASU do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 should be applied retrospectively. Early adoption is permitted. The ASU became effective for Trustmark’s financial statements beginning January 1, 2012. For Trustmark, the impact of the ASU is a change in presentation only and did not have a significant impact on Trustmark’s consolidated financial statements.

ASU 2011-04, “Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” The ASU is the result of joint efforts by the FASB and IASB to develop a single, converged fair value framework on how to measure fair value and on what disclosures to provide about fair value measurements. While the ASU is largely consistent with existing fair value measurement principles in U.S. GAAP, it expands existing disclosure requirements for fair value measurements and makes other amendments. Many of these amendments were made to eliminate unnecessary wording differences between U.S. GAAP and IFRSs. However, some could change how fair value measurement guidance is applied. The ASU became effective for Trustmark’s financial statements beginning January 1, 2012, and did not have a significant impact on Trustmark’s consolidated financial statements. The required disclosures are reported in Note 16 – Fair Value.

ASU 2011-03, “Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements.” The ASU eliminates from U.S. GAAP the requirement for entities to consider whether a transferor has the ability to repurchase the financial assets in a repurchase agreement. This requirement was one of the criteria that entities used to determine whether the transferor maintained effective control. Although entities must consider all the effective-control criteria under ASC 860, the elimination of this requirement may lead to more conclusions that a repurchase arrangement should be accounted for as a secured borrowing rather than as a sale. The guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. The ASU became effective for Trustmark’s financial statements beginning January 1, 2012, and did not have a significant impact on Trustmark’s consolidated financial statements.

Somerville Bank & Trust Company (Somerville), headquartered in Somerville, Tennessee, provides banking services in the eastern Memphis metropolitan statistical area (MSA) through five offices. At March 31, 2012, Somerville had total assets of $197.9 million.

Capital Trusts

Trustmark Preferred Capital Trust I (Trustmark Trust) is a Delaware trust affiliate formed in 2006 to facilitate a private placement of $60.0 million in trust preferred securities. As defined in applicable accounting standards, Trustmark Trust is considered a variable interest entity for which Trustmark is not the primary beneficiary. Accordingly, the accounts of the trust are not included in Trustmark’s consolidated financial statements.

Executive Overview

While the economy has shown moderate signs of improvement, the outlook remains uncertain. Recent indicators of spending, production and job market activity have shown positive trends; however, unemployment remains elevated, the housing sector continues to be depressed and global markets continue to pose a downside risk. Consumer confidence posted a sizable improvement during the latter part of the first quarter of 2012 after a decline in January as consumers’ assessment of current business and labor markets turned more optimistic. Doubts surrounding the sustainability of these signs of improvement are expected to persist for some time, especially as the magnitude of economic distress facing local markets place continued pressure on asset growth, asset quality and earnings, with the potential for undermining the stability of the banking organizations that serve these markets.

The European financial crisis has created risks and uncertainties affecting the global economy. As global markets react to potential resolutions of the European financial crisis and potential economic policy changes in Europe, assets, liabilities and cash flows with no direct connection to the European Union could be influenced. The potential impact on markets within the United States and on the economy of the United States is difficult to predict. Trustmark has no direct or indirect exposure to any debt of European sovereign and non-sovereign issuers, nor is it dependent upon any funding sources in the Eurozone for any short- or long-term liquidity.

Management has continued to carefully monitor the impact of illiquidity in the financial markets, values of securities and other assets, loan performance, default rates and other financial and macro economic indicators, in order to navigate the challenging economic environment. To reduce exposure to certain loan categories, Management has continued to reduce certain loan classifications, including construction, land development and other land loans and indirect auto loans.

TNB did not make significant changes to its loan underwriting standards during the first three months of 2012. TNB’s willingness to make loans to qualified applicants that meet its traditional, prudent lending standards has not changed. TNB adheres to interagency guidelines regarding concentration limits of commercial real estate loans. As a result of the economic downturn, TNB remains cautious in granting credit involving certain categories of real estate as well as making exceptions to its loan policy.

Management has continued its practice of maintaining excess funding capacity to provide Trustmark with adequate liquidity for its ongoing operations. In this regard, Trustmark benefits from its strong deposit base, its highly liquid investment portfolio and its access to funding from a variety of external funding sources such as upstream Federal funds lines, FHLB advances and brokered deposits.

Critical Accounting Policies

Trustmark’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP) and follow general practices within the financial services industry. Application of these accounting principles requires Management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the consolidated financial statements; accordingly, as this information changes, actual financial results could differ from those estimates.

Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. There have been no significant changes in Trustmark’s critical accounting estimates during the first three months of 2012.

Recent Legislative Developments

On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act) into law. The Dodd-Frank Act represents very broad and complex legislation that enacts sweeping changes to the financial services industry. As the Dodd-Frank Act continues to turn into specific regulatory requirements, there will be further business impacts across a myriad of industries, not just banking. Some of those impacts are readily anticipated such as the change to interchange fees, which can be found in the Bank Card and Other Fees section of Noninterest Income included elsewhere in this document. However, other impacts are subtle and do not stem directly from language in the new law. Many of these more subtle impacts will likely only emerge after months and perhaps years of further analysis and evaluation. In addition, certain provisions that affect deposit insurance assessments, payment of interest on demand deposits and interchange fees could increase the costs associated with deposits as well as place limitations on certain revenues those deposits may generate. Finally, implementation of certain significant provisions of the Dodd-Frank Act will continue to occur over a multi-year period. Because many aspects of the Dodd-Frank Act are subject to further rulemaking and will take effect over several years, it is difficult to anticipate the potential impact on Trustmark and its customers. It is clear, however, that the implementation of the Dodd-Frank Act will require Management to invest significant time and resources to evaluate the potential impact of this Act. Management will continue to evaluate this impact as more details regarding the implementation of these provisions become available.

In addition, Trustmark’s regulatory capital and liquidity requirements may be increased due to planned revisions to the existing Basel Accords (Basel III). These revisions, once finalized, will need to be implemented by U.S. bank regulators before they become binding upon Trustmark, and there is no certainty when this will occur or what form the final revisions will take. It is likely, however, that once implemented, all banking organizations subject to Basel III, including Trustmark, will be required to hold a greater amount of capital and a greater amount of common equity, than they are currently required to hold.

Financial Highlights

Trustmark reported net income available to common shareholders of $30.3 million, or basic and diluted earnings per common share of $0.47 in the first quarter of 2012, compared to $24.0 million, or basic and diluted earnings per common share of $0.38 and $0.37, respectively, in the first quarter of 2011. Trustmark’s performance during the quarter ended March 31, 2012, produced a return on average tangible common equity of 13.41% and a return on average assets of 1.25% compared to a return on average tangible common equity of 11.65% and a return on average assets of 1.02% during the quarter ended March 31, 2011. Trustmark’s Board of Directors declared a quarterly cash dividend of $0.23 per common share. The dividend is payable June 15, 2012, to shareholders of record on June 1, 2012.

At March 31, 2012, nonperforming assets totaled $181.5 million, a decrease of $8.0 million, or 4.2%, compared to December 31, 2011, and total nonaccrual loans held for investment (LHFI) were $105.8 million, representing a decrease of $4.7 million relative to December 31, 2011. Total net charge-offs for the three months ended March 31, 2012 were $1.9 million compared to total net charge-offs of $7.6 million for the same time period in 2011.

On March 16, 2012, TNB completed its merger with Bay Bank & Trust Company (Bay Bank). Trustmark paid consideration of approximately $22 million in cash and stock for all outstanding shares of Bay Bank common stock. At March 31, 2012, the carrying value of loans and deposits acquired from Bay Bank was $97.8 million and $210.7 million, respectively. Earnings for the quarter ended March 31, 2012, reflected a nonrecurring bargain purchase gain of $2.8 million which was partially offset by nonrecurring merger expenses of $1.6 million, net of taxes. Collectively, the net impact of these two items increased net income in the first quarter by approximately $1.2 million, or approximately $0.02 per share. The bargain purchase gain of $2.8 million was recognized as other noninterest income for the three months ended March 31, 2012. Included in noninterest expense 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 employee benefits, and contract termination and other expenses of $1.9 million included in other expense).

An acceleration or significantly extended deterioration in loan performance and default levels, a significant increase in foreclosure activity, a material decline in the value of Trustmark’s assets (including loans and investment securities), or any combination of more than one of these trends could have a material adverse effect on Trustmark’s financial condition or results of operations.

Non-GAAP Financial Measures

In addition to capital ratios defined by GAAP and banking regulators, Trustmark utilizes various tangible common equity measures when evaluating capital utilization and adequacy. Tangible common equity, as defined by Trustmark, represents common equity less goodwill and identifiable intangible assets.

Trustmark believes these measures are important because they reflect the level of capital available to withstand unexpected market conditions. Additionally, presentation of these measures allows readers to compare certain aspects of Trustmark’s capitalization to other organizations. These ratios differ from capital measures defined by banking regulators principally in that the numerator excludes shareholders’ equity associated with preferred securities, the nature and extent of which varies across organizations

These calculations are intended to complement the capital ratios defined by GAAP and banking regulators. Because GAAP does not include these capital ratio measures, Trustmark believes there are no comparable GAAP financial measures to these tangible common equity ratios. Despite the importance of these measures to Trustmark, there are no standardized definitions for them and, as a result, Trustmark’s calculations may not be comparable with other organizations. Also there may be limits in the usefulness of these measures to investors. As a result, Trustmark encourages readers to consider its consolidated financial statements and the notes related thereto in their entirety and not to rely on any single financial measure. The following table reconciles Trustmark’s calculation of these measures to amounts reported under GAAP.

Results of Operations

Net Interest Income

Net interest income is the principal component of Trustmark’s income stream and represents the difference, or spread, between interest and fee income generated from earning assets and the interest expense paid on deposits and borrowed funds. Fluctuations in interest rates, as well as volume and mix changes in earning assets and interest-bearing liabilities, can materially impact net interest income. The net interest margin (NIM) is computed by dividing fully taxable equivalent net interest income by average interest-earning assets and measures how effectively Trustmark utilizes its interest-earning assets in relationship to the interest cost of funding them. The accompanying Yield/Rate Analysis Table shows the average balances for all assets and liabilities of Trustmark and the interest income or expense associated with earning assets and interest-bearing liabilities. The yields and rates have been computed based upon interest income and expense adjusted to a fully taxable equivalent (FTE) basis using a 35% federal marginal tax rate for all periods shown. Loans on nonaccrual have been included in the average loan balances, and interest collected prior to these loans having been placed on nonaccrual has been included in interest income. Loan fees included in interest associated with the average loan balances are immaterial.

As previously discussed, Trustmark (through TNB) acquired Bay Bank on March 16, 2012. This acquisition resulted in additional net interest income of $247 thousand for the three months ended March 31, 2012, and year to date growth in both average interest-earning assets and average interest-bearing liabilities of $20.5 million and $24.7 million, respectively, which are included in the current period balances shown in the following three paragraphs.

Net interest income-FTE for the three months ended March 31, 2012 increased $636 thousand when compared with the same time period in 2011. The net interest margin decreased 11 basis points to 4.19% for the first three months of 2012, compared with the same time period in 2011. The decrease in net interest margin is primarily a result of a downward repricing of fixed rate assets as well as changes to Trustmark’s asset mix due to growth in lower yielding investment securities. The impact of this was partially offset by a modest decline in deposit costs and higher yields on acquired covered loans.

Average interest-earning assets for the first three months of 2012 were $8.697 billion, compared with $8.483 billion for the same time period in 2011, an increase of $213.2 million. The growth in average earning assets was primarily due to an increase in average total securities of $223.1 million, or 9.6%, during the first three months of 2012. The increase in securities was offset by a decrease in average other earning assets of $13.7 million, or 28.7%, during the first three months of 2012. The decrease in average other earning assets is due to a decrease in FHLB and FRB stock of $8.5 million, or 23.5%, and a decrease in exchange-traded derivative instruments of $5.2 million, or 54.1%, during the first three months of 2012. During the first three months of 2012, interest on securities-taxable decreased $1.6 million, or 8.0%, as the yield on taxable securities decreased 64 basis points when compared with the same time period in 2011 due to the run-off of higher yielding securities replaced at lower yields. During the first three months of 2012, interest and fees on loans-FTE decreased $398 thousand, or 0.5%, due to lower average loan balances while the yield on loans fell slightly to 5.18% compared to 5.25% during the same time period in 2011. As a result of these factors, interest income-FTE decreased $2.0 million, or 2.0%, when the first three months of 2012 is compared with the same time period in 2011. The impact of these changes is also illustrated by the decline in the yield on total earning assets, which fell from 4.86% for the first three months of 2011 to 4.60% for the same time period in 2012, a decrease of 26 basis points.

Average interest-bearing liabilities for the first three months of 2012 totaled $6.534 billion compared with $6.612 billion for the same time period in 2011, a decrease of $78.4 million, or 1.2%. During the first three months of 2012, average interest-bearing deposits increased $301.9 million, or 5.4%, while the combination of federal funds purchased, securities sold under repurchase agreements and other borrowings decreased by $380.2 million, or 37.5%. The overall yield on interest-bearing liabilities declined 16 basis points during the first three months of 2012 when compared with the same time period in 2011, primarily due to a reduction in the costs of certificates of deposit and high yield money market accounts. As a result of these factors, total interest expense for the first three months of 2012 decreased $2.7 million, or 23.0%, when compared with the same time period in 2011.

Provision for Loan Losses, LHFI

The provision for loan losses, LHFI is determined by Management as the amount necessary to adjust the allowance for loan losses to a level, which, in Management’s best estimate, is necessary to absorb probable losses within the existing loan portfolio. The provision for loan losses reflects loan quality trends, including the levels of and trends related to nonaccrual loans, past due loans, potential problem loans, criticized loans, net charge-offs or recoveries and growth in the loan portfolio among other factors. Accordingly, the amount of the provision reflects both the necessary increases in the allowance for loan losses related to newly identified criticized loans, as well as the actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools. As shown in the table below, the provision for loan losses, excluding acquired loans, for the first three months of 2012 totaled $3.3 million, or 0.22% of average loans, compared with $7.5 million, or 0.50% of average loans, for the same time period in 2011. Reduced loan provisioning during the first three months of 2012 was a result of decreased levels of criticized loans, lower net charge-offs, adequate reserves established in prior years for both new and existing impaired loans and a smaller overall loan portfolio.

Trustmark continues to devote significant resources to managing credit risks resulting from the slowdown in commercial developments of residential real estate. Management believes that the construction and land development portfolio is appropriately risk rated and adequately reserved based on current conditions.

See the section captioned “LHFI and Allowance for Loan Losses, LHFI” elsewhere in this discussion for further analysis of the provision for loan losses, which includes the table of nonperforming assets.

Noninterest Income

Trustmark’s noninterest income continues to play an important role in improving net income and total shareholder value and represents 33.0% and 29.6% of total revenue, before securities gains, net for the first three months of 2012 and 2011, respectively. Total noninterest income before securities gains, net for the first three months of 2012 increased $6.4 million compared to the same time period in 2011. The comparative components of noninterest income for the periods ended March 31, 2012 and 2011 are shown in the accompanying table:

Service Charges on Deposit Accounts

Service charges on deposit accounts during the first three months of 2012 totaled $12.2 million, an increase of $304 thousand from the same time period in 2011. This slight increase was principally due to the monthly service charge fee on a personal account product Trustmark began offering during the fourth quarter of 2011. As previously reported, Trustmark continues to review selected components of its overdraft programs, specifically its processing sequences. A modification presently under review may reduce service charges included in noninterest income by approximately $2.5 million on an annual basis in future periods.

Bank Card and Other Fees

Bank card and other fees totaled $7.4 million during the first three months of 2012 compared with $6.5 million for the same time period in 2011. Bank card and other fees consist primarily of fees earned on bank card products as well as fees on various bank products and services and safe deposit box fees. The increase was primarily the result of growth in fees earned on bank card products due to increased consumer utilization.

The Dodd-Frank Act amended the Electronic Fund Transfer Act to authorize the Federal Reserve Board (FRB) to issue regulations regarding any interchange fee that an issuer may receive or charge for an electronic debit card transaction. On June 29, 2011, the FRB issued a final rule (Regulation II - Debit Card Interchange Fees and Routing) establishing standards for debit card interchange fees. Under the final rule, the maximum permissible interchange fee that an issuer may receive for an electronic debit transaction will be the sum of 21 cents per transaction and five basis points multiplied by the value of the transaction. This provision regarding debit card interchange fees was effective as of October 1, 2011. In addition, the FRB also approved an interim rule that allows for an upward adjustment of no more than one cent to an issuer's debit card interchange fee if the issuer develops and implements policies and procedures reasonably designed to achieve the fraud-prevention standards set out in the interim rule. The fraud-prevention adjustment was effective as of October 1, 2011, concurrent with the debit card interchange fee limits.

In accordance with the statute, issuers that, together with their affiliates, have assets of less than $10.0 billion on the annual measurement date (December 31) are exempt from the debit card interchange fee standards. At December 31, 2011, the annual measurement date, Trustmark had assets of less than $10.0 billion, therefore, no impact of the FRB final rule (Regulation II - Debit Card Interchange Fees and Routing) to noninterest income is expected during 2012. However, if and when Trustmark has assets of greater than $10.0 billion, the effect of the FRB final rule could reduce noninterest income by $6.0 million to $8.0 million on an annual basis. Management is continuing to evaluate Trustmark’s product structure and services to offset any potential impact of the FRB final rule, if and when Trustmark's assets exceed the $10.0 billion threshold.

Mortgage Banking, Net

Net revenues from mortgage banking were $7.3 million during the first three months of 2012 compared with $4.7 million for the same time period in 2011. As shown in the accompanying table, net mortgage servicing income increased to $3.9 million for the first three months of 2012 compared to $3.6 million for the same time period in 2011. Loans serviced for others totaled $4.6 billion at March 31, 2012 compared with $4.4 billion at March 31, 2011.

The following table illustrates the components of mortgage banking revenues included in noninterest income in the accompanying income statements:

Mortgage Banking Income

n/m - percentage changes greater than +/- 100% are not considered meaningful

As part of Trustmark’s risk management strategy, exchange-traded derivative instruments are utilized to offset changes in the fair value of MSR attributable to changes in interest rates. Changes in the fair value of these exchange-traded derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative ineffectiveness of $1.0 million and net positive ineffectiveness of $263 thousand for the three months ended March 31, 2012 and 2011, respectively.

Representing a significant component of mortgage banking income are gains on the sales of loans, which equaled $6.5 million during the first three months of 2012 compared with $3.1 million for the same time period in 2011. The growth in the gain on sales of loans during the first three months of 2012 resulted from an increase in loan sales from secondary marketing activities as well as higher profit margins. Loan sales totaled $371.8 million during the first three months of 2012, an increase of $132.1 million when compared with the same time period in 2011.

Insurance Commissions

Insurance commissions were $6.6 million during the first three months of 2012 compared with $6.5 million for the same time period in 2011. The increase in insurance commissions experienced during the first three months of 2012 was led by commission volume on commercial property and casualty policies and by a small improvement in personal coverage. Improvements in these business lines compensated for a small decline in construction bonding due to a weak contractors’ market and lower life insurance sales. Downward rate pressures on insurable risks have begun to subside, with some lines experiencing price increases. General business activity outside of construction has slightly improved which resulted in a small increase in the demand for coverage on inventories, property, equipment, general liability and workers’ compensation.

Wealth Management

Wealth management income totaled $5.5 million for the first three months of 2012 compared with $6.0 million for the same time period in 2011. Wealth management consists of income related to investment management, trust and brokerage services. Brokerage services experienced slight declines when compared to the same period last year, however, has shown an improved trend over late 2011. The remaining revenue declines are explained by below-trend fee revenues on investment advisory and retirement plan services. These fees tend to lag the performance of the financial markets and are expected to improve in response to recent positive market performance. At March 31, 2012 and 2011, Trustmark held assets under management and administration of $7.5 billion and $7.6 billion, respectively, and brokerage assets of $1.3 billion.

Other Income, Net

The following table illustrates the components of other income, net included in noninterest income for the periods presented:

Other Income, Net

($ in thousands)
	Three Months Ended March 31,
	2012			2011			$ Change			% Change
Partnership amortization for tax credit purposes	$	(1,422	)	$	(1,122	)	$	(300	)		26.7	%
Bargain purchase gain on acquisition		2,754			-			2,754			n/m
Decrease in FDIC indemnification asset		(81	)		-			(81	)		n/m
Other miscellaneous income		2,507			1,884			623			33.1	%
Total other, net	$	3,758		$	762		$	2,996			n/m

n/m - percentage changes greater than +/- 100% are not considered meaningful

Other income, net for the first three months of 2012 was $3.8 million compared with $762 thousand for the same time period in 2011. The increase of $3.0 million during the first three months of 2012 reflects a nonrecurring bargain purchase gain of $2.8 million resulting from TNB’s acquisition of Bay Bank during the first quarter of 2012. The increase in other miscellaneous income for the first three months of 2012 was primarily due to the receipt of a $780 thousand non-refundable arranger fee as lead syndicator for a large syndicated loan.

Security Gains, Net

From time to time, Trustmark manages the risk and return profile of the securities portfolio through sales of available for sale securities prior to their maturity. During the first three months of 2012, Trustmark sold approximately $35.2 million in securities generating a gain of $1.1 million. Trustmark did not sell any securities during the first three months of 2011.

Noninterest Expense

Trustmark’s noninterest expense for the first three months of 2012 increased $5.8 million, or 7.2%, when compared with the same time period in 2011. Excluding business combinations, noninterest expense for the first three months of 2012 increased $2.6 million, or 3.2%, when compared with the same time period in 2011. The increase during the first three months of 2012 was primarily attributable to growth in salaries and benefits, loan expenses, and a one time transaction expense relating to the Bay Bank acquisition. Management considers disciplined expense management a key area of focus in the support of improving shareholder value. The comparative components of noninterest expense for the periods ended March 31, 2012 and 2011 are shown in the accompanying table:

Noninterest Expense

($ in thousands)
	Three Months Ended March 31,
	2012		2011		$ Change			% Change
Salaries and employee benefits	$	46,432	$	44,036	$	2,396			5.4	%
Services and fees		10,747		10,270		477			4.6	%
Net occupancy-premises		4,938		5,073		(135	)		-2.7	%

FDIC assessment expense		1,775		2,750		(975	)		-35.5	%
Other expense		13,068		9,532		3,536			37.1	%
Total noninterest expense	$	85,774	$	80,018	$	5,756			7.2	%

n/m - percentage changes greater than +/- 100% are not considered meaningful

Salaries and Employee Benefits

Salaries and employee benefits, the largest category of noninterest expense, were $46.4 million for the first three months of 2012 compared with $44.0 million for the same time period in 2011. This increase primarily reflects modest general merit increases, higher general incentive costs resulting from improved corporate performance and higher costs for employee retirement programs as well as $1.1 million in additional salaries and employee benefits resulting from the Heritage and Bay Bank acquisitions. Salaries and employee benefits expense for Bay Bank included a non-routine transaction expense of $672 thousand for change in control and severance expense.

FDIC Assessment Expense

During the first three months of 2012, FDIC insurance expense decreased $975 thousand, or 35.5% when compared with the same time period in 2011, resulting from the implementation of the FDIC’s revised deposit insurance assessment methodology during the second quarter of 2011. As required by the Dodd-Frank Act, on April 1, 2011, the FDIC revised the deposit insurance assessment system to base assessments on the average total consolidated assets of insured depository institutions less the average tangible equity during the assessment period. In addition, the Dodd-Frank Act increased the minimum reserve ratio for the Deposit Insurance Fund from 1.15% to 1.35% of estimated insurable deposits, or the comparable percentage of the assessment base by September 30, 2020. The FDIC must offset the effect of the increase in the minimum reserve ratio on insured depository institutions with total consolidated assets of less than $10.0 billion. With total assets slightly below $10.0 billion at March 31, 2012, Trustmark benefitted from the change in the assessment methodology. Should Trustmark qualify as a large institution, generally one with at least $10.0 billion in assets, Management estimates the change in the assessment methodology would have an immaterial impact on Trustmark’s results of operations.

Other Expense

Other noninterest expense consisted of the following for the periods presented:

Other Expense

($ in thousands)
	Three Months Ended March 31,
	2012		2011		$ Change			% Change
Loan expense	$	5,525	$	3,670	$	1,855			50.5	%
Non-routine transaction expenses on acquisition		1,917		-		1,917			n/m
Amortization of intangibles		710		775		(65	)		-8.4	%
Other miscellaneous expense		4,916		5,087		(171	)		-3.4	%
Total other expense	$	13,068	$	9,532	$	3,536			37.1	%

n/m - percentage changes greater than +/- 100% are not considered meaningful

During the first three months of 2012, other expenses increased $3.5 million, or 37.1%, compared to the same time period in 2011. The growth in other expenses during the first three months of 2012 was primarily due to an increase in loan expenses that resulted from higher mortgage foreclosure expenses and a non-routine transaction expense for contract termination and other expenses of $1.9 million resulting from the Bay Bank acquisition.

During the normal course of business, Trustmark's mortgage banking operations originates and sells certain loans to investors in the secondary market. Trustmark has continued to experience a manageable level of investor repurchase demands. Trustmark is subject to losses in its loan servicing portfolio due to loan foreclosures. For loans sold without recourse, Trustmark has obligations to either repurchase the outstanding principal balance of a loan or make the purchaser whole for the economic benefits of a loan if it is determined that the loan sold was in violation of representations or warranties made by Trustmark at the time of the sale, herein referred to as mortgage loan servicing putback expenses. Such representations and warranties typically include those made regarding loans that had missing or insufficient file documentation and/or loans obtained through fraud by borrowers or other third parties such as appraisers. The total mortgage loan servicing putback expenses incurred by Trustmark during the first three months of 2012 were $1.9 million, compared to $643 thousand for the same time period in 2011. Trustmark operates a conservative, full service mortgage banking business and is confident in its mortgage foreclosure processes. Trustmark has not engaged in "robo-signing" and has not participated in private label securitizations, both of which have been a cause of concern in the mortgage industry. Trustmark works diligently to keep borrowers in their homes, resorting to foreclosure only as a last option.

Segment Information

Results of Segment Operations

Trustmark’s operations are managed along three operating segments: General Banking, Wealth Management and Insurance. General Banking is primarily responsible for all traditional banking products and services, including loans and deposits. For financial information by reportable segment, please see Note 18 – Segment Information in the accompanying notes to the consolidated financial statements included elsewhere in this report. The following discusses changes in the financial results of each reportable segment for the three months ended March 31, 2012 and 2011.

General Banking

The General Banking Division is responsible for all traditional banking products and services including a full range of commercial and consumer banking services such as checking accounts, savings programs, overdraft facilities, commercial, installment and real estate loans, home equity loans and lines of credit, drive-in and night deposit services and safe deposit facilities offered through approximately 170 offices in Florida, Mississippi, Tennessee and Texas. The General Banking Division also consists of internal operations that include Human Resources, Executive Administration, Treasury (Funds Management), Public Affairs and Corporate Finance. Included in these operational units are expenses related to mergers, mark-to-market adjustments on loans and deposits, general incentives, stock options, supplemental retirement and amortization of core deposits. Other than Treasury, these business units are support-based in nature and are largely responsible for general overhead expenditures that are not allocated.

TNB’s acquisition of Bay Bank contributed approximately $247 thousand to net interest income, $2.8 million to noninterest income (primarily from bargain purchase gain of $2.8 million) and $2.9 million to noninterest expense of the General Banking Division during the three months ended March 31, 2012, which are also included in the current period balances shown in the following three paragraphs.

Net interest income for the three months ended March 31, 2012 increased $525 thousand when compared with the same time period in 2011, due to a decline in interest expense partially offset by lower interest income. The improvement in interest expense is primarily attributable to lower deposit costs as well as growth in average noninterest-bearing deposits, while the decline in interest income is due to the downward repricing of fixed rate assets, partially offset by an increase in average investment portfolio securities. The provision for loan losses for the three months ended March 31, 2012 totaled $3.1 million compared to $7.5 million for the same period in 2011, a decrease of $4.4 million, or 58.9%. For more information on this change, please see the analysis of the Provision for Loan Losses, excluding Acquired Loans, located elsewhere in this document.

Noninterest income for the General Banking Division increased by approximately $7.8 million during the first three months of 2012 compared to the same time period in 2011. Noninterest income for the General Banking Division represents 26.9% of total revenues for the first three months of 2012 as opposed to 21.8% for the same time period in 2011, and includes service charges on deposit accounts, bank card and other fees, mortgage banking, net, other, net and securities gains, net. For more information on these noninterest income items, please see the analysis of Noninterest Income located elsewhere in this document.

Noninterest expense for the General Banking Division increased $6.3 million during the first three months of 2012 when compared with the same time period in 2011. For more information on these noninterest expense items, please see the analysis of Noninterest Expense located elsewhere in this document.

Wealth Management

The Wealth Management Division has been strategically organized to serve Trustmark’s customers as a financial partner providing reliable guidance and sound, practical advice for accumulating, preserving, and transferring wealth. The Investment Services group and the Trust group are the primary service providers in this segment. TIA, a wholly owned subsidiary of TNB that is included in the Wealth Management Division, is a registered investment adviser that provides investment management services to individual and institutional accounts as well as The Performance Fund Family of Mutual Funds.

During the first three months of 2012, net income for the Wealth Management Division decreased $89 thousand, or 9.8%, when compared to the same time period in 2011. Noninterest income decreased $483 thousand when the first three months of 2012 are compared to the same time period in 2011. The decrease in noninterest income was due to slight declines in brokerage services and below-trend fee revenues on investment advisory and retirement plan services. For more information on the change in wealth management revenue, please see the analysis included in Noninterest Income located elsewhere in this document.

Insurance

Trustmark’s Insurance Division provides a full range of retail insurance products, including commercial risk management products, bonding, group benefits and personal lines coverage through FBBI, a Mississippi corporation and subsidiary of TNB.

During the first three months of 2012, net income for the Insurance Division increased $253 thousand, or 35.3%, when compared to the same time period in 2011. Noninterest income increased $141 thousand when the first three months of 2012 are compared to the same time period in 2011. The increase in noninterest income was primarily due to higher commission volume on commercial property and casualty policies. For more information on the change in insurance commissions, please see the analysis included in Noninterest Income located elsewhere in this document.

Income Taxes

For the three months ended March 31, 2012, Trustmark’s combined effective tax rate was 27.6% compared to 31.8% for the same time period in 2011. Trustmark invests in partnerships that provide income tax credits on a Federal and/or State basis (i.e., new market tax credits, low income housing tax credits or historical tax credits). These investments are recorded based on the equity method of accounting, which requires the equity in partnerships losses to be recognized when incurred and are recorded as a reduction in other income. The income tax credits related to these partnerships are utilized as specifically allowed by income tax law and are recorded as a reduction in income tax expense. The decrease in Trustmark's effective tax rate is mainly due to increased investment in these partnerships along with the appropriate tax credits and immaterial changes in permanent items as a percentage of pretax income.

Earning Assets

Earning assets serve as the primary revenue streams for Trustmark and are comprised of securities, loans, federal funds sold and securities purchased under reverse repurchase agreements. Average earning assets totaled $8.697 billion, or 89.2% of total assets, at March 31, 2012, compared with $8.534 billion, or 89.1% of total assets, at December 31, 2011, an increase of $162.6 million, or 1.9%.

Securities

When compared with December 31, 2011, total investment securities increased by $121.0 million during the first three months of 2012. This increase resulted primarily from purchases of U.S. Government-sponsored agency (GSE) guaranteed securities, offset by maturities and paydowns. $26.3 million of the increase in securities can be attributed to the Bay Bank acquisition. During the first three months of 2012, Trustmark sold approximately $35.2 million in securities, generating a gain of $1.1 million. Trustmark did not sell any securities during the first three months of 2011.

The securities portfolio is utilized by Management to manage interest rate risk, generate interest income, provide liquidity and use as collateral for public deposits and wholesale funding. Risk and return can be adjusted by altering duration, composition and/or balance of portfolio. The weighted-average life of the portfolio is unchanged at 3.6 years at March 31, 2012, compared to December 31, 2011.

Available for sale (AFS) securities are carried at their estimated fair value with unrealized gains or losses recognized, net of taxes, in accumulated other comprehensive income (loss), a separate component of shareholders’ equity. At March 31, 2012, AFS securities totaled $2.596 billion, which represented 98.0% of the securities portfolio, compared to $2.469 billion, or 97.7%, at December 31, 2011. At March 31, 2012, unrealized gains, net on AFS securities totaled $69.6 million compared with unrealized gains, net of $73.7 million at December 31, 2011. At March 31, 2012, AFS securities consisted of obligations of states and political subdivisions, GSE guaranteed mortgage-related securities, direct obligations of U.S. Government sponsored agencies, asset-backed securities, and corporate debt securities.

Held to maturity (HTM) securities are carried at amortized cost and represent those securities that Trustmark both intends and has the ability to hold to maturity. At March 31, 2012, HTM securities totaled $52.0 million and represented 2.0% of the total securities portfolio, compared with $57.7 million, or 2.3%, at December 31, 2011.

Management continues to focus on asset quality as one of the strategic goals of the securities portfolio, which is evidenced by the investment of approximately 90% of the portfolio in U.S. Government agency-backed obligations and other AAA rated securities. None of the securities owned by Trustmark are collateralized by assets which are considered sub-prime. Furthermore, outside of membership in the Federal Home Loan Bank of Dallas, Federal Home Loan Bank of Atlanta, Independent Bankers Bank of Florida, and Federal Reserve Bank, Trustmark does not hold any equity investment in government sponsored entities.

As of March 31, 2012, Trustmark did not hold securities of any one issuer with a carrying value exceeding ten percent of total shareholders’ equity, other than certain U.S. government-sponsored agencies which are exempt from inclusion. Management continues to closely monitor the credit quality as well as the ratings of the debt and mortgage-backed securities issued by the U.S. Government sponsored entities and held in Trustmark’s securities portfolio in light of issues currently facing these entities.

The following tables present Trustmark’s securities portfolio by amortized cost and estimated fair value and by credit rating at March 31, 2012:

Securities Portfolio by Credit Rating (1)

The table presenting the credit rating of Trustmark’s securities is formatted to show the securities according to the credit rating category, and not by category of the underlying security. At March 31, 2012, approximately 91.4% of the available for sale securities are rated AAA and the same is true with respect to 22.3% of held to maturity securities, which are carried at amortized cost.

Loans Held for Sale

At March 31, 2012, loans held for sale totaled $227.4 million, consisting of $174.3 million of residential real estate mortgage loans in the process of being sold to third parties and $53.2 million of Government National Mortgage Association (GNMA) optional repurchase loans. At December 31, 2011, loans held for sale totaled $216.6 million, consisting of $157.7 million in residential real estate mortgage loans in the process of being sold to third parties and $58.8 million in GNMA optional repurchase loans. Please refer to the nonperforming assets table that follows for information on GNMA loans eligible for repurchase which are past due 90 days or more.

GNMA optional repurchase programs allow financial institutions to buy back individual delinquent mortgage loans that meet certain criteria from the securitized loan pool for which the institution provides servicing. At the servicer's option and without GNMA's prior authorization, the servicer may repurchase such a delinquent loan for an amount equal to 100 percent of the remaining principal balance of the loan. This buy-back option is considered a conditional option until the delinquency criteria are met, at which time the option becomes unconditional. When Trustmark is deemed to have regained effective control over these loans under the unconditional buy-back option, the loans can no longer be reported as sold and must be brought back onto the balance sheet as loans held for sale, regardless of whether Trustmark intends to exercise the buy-back option. These loans are reported as held for sale with the offsetting liability being reported as short-term borrowings. Trustmark did not exercise its buy-back option on any delinquent loans serviced for GNMA during the first three months of 2012 or 2011.

LHFI and Allowance for Loan Losses, LHFI

LHFI

LHFI at March 31, 2012 totaled $5.775 billion compared to $5.857 billion at December 31, 2011, a decrease of $82.7 million. These declines are directly attributable to paydowns in 1-4 family mortgage loans as well as a strategic focus to reduce certain loan classifications, specifically construction, land development and other land loans, and the decision in prior years to discontinue indirect consumer auto loan financing. The 1-4 family mortgage loan portfolio decline $38.6 million was due to paydowns in the portfolio since December 31, 2011. The $8.6 million decline in construction, land development and other land loans was primarily attributable to reductions in Trustmark’s Florida and Mississippi markets of approximately $8.0 million since December 31, 2011. The consumer loan portfolio decrease of $33.0 million primarily represents a decrease in the indirect consumer auto portfolio. The indirect consumer auto portfolio balance at March 31, 2012 was $64.8 million compared with $85.1 million at December 31, 2011. The declines in these classifications reflect implementation of Management’s determination to reduce overall exposure to these types of assets.

The table below shows the carrying value of the LHFI portfolio for each of the periods presented:

LHFI by Type

($ in thousands)
	March 31,		December 31,
	2012		2011
Loans secured by real estate:
Construction, land development and other land loans	$	465,486	$	474,082
Secured by 1- 4 family residential properties		1,722,357		1,760,930
Secured by nonfarm, nonresidential properties		1,419,902		1,425,774
Other		199,400		204,849
Commercial and industrial loans		1,142,813		1,139,365
Consumer loans		210,713		243,756
Other loans		614,082		608,728
LHFI		5,774,753		5,857,484
Less allowance for loan losses, LHFI		90,879		89,518
Net LHFI	$	5,683,874	$	5,767,966

In the following tables, LHFI reported by region (along with related nonperforming assets and net charge-offs) are associated with location of origination except for loans secured by 1-4 family residential properties (representing traditional mortgages), credit cards and indirect consumer auto loans. These loans are included in the Mississippi Region because they are centrally decisioned and approved as part of a specific line of business located at Trustmark’s headquarters in Jackson, Mississippi.

The LHFI composition by region at March 31, 2012 is illustrated in the following tables and reflects a diversified mix of loans by region.

(1) Excludes Acquired Loans.

Trustmark makes loans in the normal course of business to certain directors, their immediate families and companies in which they are principal owners. Such loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons and do not involve more than the normal risk of collectibility at the time of the transaction.

There is no industry standard definition of “subprime loans.” Trustmark categorizes certain loans as subprime for its purposes using a set of factors, which Management believes are consistent with industry practice. TNB has not originated or purchased subprime mortgages. At March 31, 2012, Trustmark held “alt A” mortgages with an aggregate principal balance of $3.5 million (0.09% of total loans secured by real estate at that date). These “alt A” loans have been originated by Trustmark as an accommodation to certain Trustmark customers for whom Trustmark determined that such loans were suitable under the purposes of the Fannie Mae “alt A” program and under Trustmark’s loan origination standards. Trustmark does not have any no-interest loans, other than a small number of loans made to customers that are charitable organizations, the aggregate amount of which is not material to Trustmark’s financial condition or results of operations.

Allowance for Loan Losses, LHFI

The allowance for loan losses is established through provisions for estimated loan losses charged against net income. The allowance reflects Management’s best estimate of the probable loan losses related to specifically identified loans as well as probable incurred loan losses in the remaining loan portfolio and requires considerable judgment. The allowance is based upon Management’s current judgments and the credit quality of the loan portfolio, including all internal and external factors that impact loan collectibility. Accordingly, the allowance is based upon both past events and current economic conditions.

Trustmark’s allowance has been developed using different factors to estimate losses based upon specific evaluation of identified individual LHFI, excluding acquired loans, considered impaired, estimated identified losses on various pools of loans and/or groups of risk rated LHFI with common risk characteristics and other external and internal factors of estimated probable losses based on other facts and circumstances.

Trustmark’s allowance for loan loss methodology is based on guidance provided in SAB No. 102 as well as other regulatory guidance. The level of Trustmark’s allowance reflects Management’s continuing evaluation of specific credit risks, loan loss experience, current loan portfolio growth, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. This evaluation takes into account other qualitative factors including recent acquisitions; national, regional and local economic trends and conditions; changes in industry and credit concentration; changes in levels and trends of delinquencies and nonperforming loans; changes in levels and trends of net charge-offs; and changes in interest rates and collateral, financial and underwriting exceptions.

Trustmark’s allowance for loan loss methodology delineates the commercial purpose and commercial construction loan portfolios into nine separate loan types (or pools), which had similar characteristics, such as, repayment, collateral and risk profiles. The nine basic loan pools are further segregated into Trustmark’s four key market regions, Florida, Mississippi, Tennessee and Texas, to take into consideration the uniqueness of each market. A 10-point risk rating system is utilized for each separate loan pool to apply a reserve factor consisting of quantitative and qualitative components to determine the needed allowance by each loan type. As a result, there are 360 risk rate factors for commercial loan types. The nine separate pools are segmented below:

Commercial Purpose Loans

Real Estate – Owner Occupied

Real Estate – Non-Owner Occupied

Non-Working Capital

Land

Catastrophe

At March 31, 2012, the allowance for loan losses, LHFI, was $90.9 million, an increase of $1.4 million when compared with December 31, 2011. Total allowance coverage of nonperforming LHFI, excluding impaired LHFI, at March 31, 2012, was 181.1%, compared to 194.2% at December 31, 2011. Allocation of Trustmark’s $90.9 million allowance for loan losses, LHFI, represented 1.97% of commercial loans and 0.75% of consumer and home mortgage loans, resulting in an allowance to total LHFI of 1.57% as of March 31, 2012. This compares with an allowance to total LHFI of 1.53% at December 31, 2011, which was allocated to commercial loans at 1.91% and to consumer and mortgage loans at 0.76%.

Net charge-offs for the first three months of 2012 totaled $1.9 million, or 0.13% of average LHFI, compared to $7.6 million, or 0.51% of average LHFI, during the same time period in 2011. This decrease can be primarily attributed to a slowing in the decline of property values in commercial developments of residential real estate along with a substantial reduction in auto finance charge-offs. The net charge-offs exceeded the provisions for Florida, Tennessee and Texas for the first three months of 2012 because a large portion of charge-offs had been fully reserved in prior periods. Management continues to monitor the impact of real estate values on borrowers and is proactively managing these situations.

(2) - Mississippi includes Central and Southern Mississippi Regions

(3) - Tennessee includes Memphis, Tennessee and Northern Mississippi Regions

Trustmark’s loan policy dictates the guidelines to be followed in determining when a loan is charged-off. Commercial purpose loans are charged-off when a determination is made that the loan is uncollectible and continuance as a bankable asset is not warranted. Consumer loans secured by 1-4 family residential real estate are generally charged-off or written down when the credit becomes severely delinquent, and the balance exceeds the fair value of the property less costs to sell. Non-real estate consumer purpose loans, including both secured and unsecured, are generally charged-off in full during the month in which the loan becomes 120 days past due. Credit card loans are generally charged-off in full when the loan becomes 180 days past due.

Nonperforming Assets, excluding Acquired Loans and Covered Other Real Estate

Nonperforming assets totaled $181.5 million at March 31, 2012, a decrease of $8.0 million relative to December 31, 2011. Collectively, total nonperforming assets to total LHFI and noncovered other real estate at March 31, 2012 was 2.99% compared to 3.08% at December 31, 2011. During the first three months of 2012, nonperforming loans decreased $4.7 million, or 4.2%, relative to December 31, 2011 to total $105.8 million, or 1.76% of total LHFI, marking eight consecutive quarters of improvement. Foreclosed real estate, excluding covered other real estate, decreased $3.3 million from the prior quarter to total $75.7 million.

(1) Acquired noncovered loans were included in LHFI at December 31, 2011.

On April 15, 2011, TNB entered into a purchase and assumption agreement with the FDIC in which TNB agreed to assume all of the deposits and essentially all of the assets of Heritage. Loans comprise the majority of the assets acquired and $97.8 million, or 91% of total loans acquired, are subject to the loss-share agreement with the FDIC whereby TNB is indemnified against a portion of the losses on covered loans and covered other real estate. The loans acquired from Heritage that are covered by loss-share agreement are presented as covered loans in the accompanying consolidated financial statements.

TNB accounts for acquired impaired loans under FASB ASC Topic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” An acquired loan is considered impaired when there is evidence of credit deterioration since the origination and it is probable at the date of acquisition that TNB would be unable to collect all contractually required payments. Revolving credit agreements such as home equity lines are excluded from acquired impaired loan accounting requirements. TNB acquired $5.7 million and $3.8 million of revolving credit agreements, at fair value, in the Bay Bank and Heritage acquisitions, respectively, consisting mainly of home equity loans and commercial asset-based lines of credit, where the borrower had revolving privileges on the acquisition date. As such, TNB has accounted for such revolving covered loans in accordance with accounting requirements for acquired nonimpaired loans.

The following table illustrates changes in the carrying value of the acquired loans for the periods presented:

(1)	Acquired noncovered loans were included in LHFI at December 31, 2011.

(2)	Acquired nonimpaired loans consist of revolving credit agreements that are not in scope for FASB ASC Topic 310-30.

(3)	Includes $4.3 million for loan recoveries and an adjustment to payments recorded for covered acquired impaired loans,which was reported as "Changes in expected cash flows" at December 31, 2011.

(4)	Fair value of loans acquired from Bay Bank on March 16, 2012.

(5)	Accretion to interest income for Bay Bank since acquisition at March 16, 2012 is considered immaterial.

Covered Other Real Estate

All other real estate acquired in a FDIC-assisted acquisition, such as Heritage, that is subject to a FDIC loss-share agreement is referred to as covered other real estate and reported separately in Trustmark’s consolidated balance sheets. Covered other real estate is reported exclusive of expected reimbursement cash flows from the FDIC. Foreclosed covered loan collateral is transferred into covered other real estate at the collateral’s net realizable value, less selling costs.

Covered other real estate by type of property consisted of the following for the periods presented:

FDIC Indemnification Asset

TNB has elected to account for amounts receivable under the loss-share agreement as an indemnification asset in accordance with FASB ASC Topic 805, “Business Combinations.” 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. The difference between the present value and the undiscounted cash flows TNB expects to collect from the FDIC is accreted into noninterest income over the life of the FDIC indemnification asset. The FDIC indemnification asset is presented net of any true-up provision, pursuant to the provisions of the loss-share agreement, due to the FDIC at the termination of the loss-share agreement.

The following table illustrates changes in the FDIC indemnification asset for the periods presented:

FDIC Indemnification Asset

($ in thousands)

Balance at January 1, 2011	$	-
Additions from acquisition		33,333

Transfers to FDIC claims receivable		-
Change in expected cash flows		(93	)
Change in FDIC true-up provision		(60	)
Balance at March 31, 2012	$	28,260

(1) The decrease was due to loan pay-offs, improved cash flow projections, and lower loss expectations for covered loans.

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. 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. TNB’s FDIC true-up provision totaled $661 thousand and $601 thousand at March 31, 2012 and December 31, 2011, respectively.

Other Earning Assets

Federal funds sold and securities purchased under reverse repurchase agreements were $6.3 million at March 31, 2012, a decrease of $3.0 million when compared with December 31, 2011. Trustmark utilizes these products as offerings for its correspondent banking customers as well as a short-term investment alternative whenever it has excess liquidity.

Deposits and Other Interest-Bearing Liabilities

Trustmark’s deposit base is its primary source of funding and consists of core deposits from the communities Trustmark serves. Deposits include interest-bearing and noninterest-bearing demand accounts, savings, money market, certificates of deposit and individual retirement accounts. Total deposits were $8.091 billion at March 31, 2012, compared with $7.566 billion at December 31, 2011, an increase of $524.4 million, or 6.9%. The growth in deposits is comprised of an increase in interest-bearing deposits of $533.5 million and a decrease in noninterest-bearing deposits of $9.2 million. The increase in interest-bearing deposits resulted primarily from seasonal growth in public deposits of $422.7 million as well as $149.7 million in deposits from the Bay Bank acquisition. Partially offsetting the increase in interest-bearing deposits was a decrease in certificate of deposit account balances, excluding Bay Bank, of $25.7 million as Trustmark continued its efforts to reduce high-cost deposit balances. Excluding Bay Bank, Trustmark experienced noninterest-bearing deposit growth among all categories of $30.2 million.

Trustmark uses short-term borrowings to fund growth of earning assets in excess of deposit growth. Short-term borrowings consist primarily of federal funds purchased, securities sold under repurchase agreements and short-term FHLB advances. Short-term borrowings totaled $336.9 million at March 31, 2012, a decrease of $355.2 million when compared with $692.1 million at December 31, 2011. Of these amounts, $215.9 million and $239.4 million, respectively, were customer related transactions, such as commercial sweep repo balances. The decrease in short-term borrowings resulted primarily from declines of $349.6 million in federal funds purchased and securities sold under repurchase agreements as funding pressures lessened due to strong deposit growth.

Legal Environment

Off-Balance Sheet Arrangements

Trustmark makes commitments to extend credit and issues standby and commercial letters of credit in the normal course of business in order to fulfill the financing needs of its customers. These loan commitments and letters of credit are off-balance sheet arrangements.

Commitments to extend credit are agreements to lend money to customers pursuant to certain specified conditions. Commitments generally have fixed expiration dates or other termination clauses. Since many of these commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Trustmark applies the same credit policies and standards as it does in the lending process when making these commitments. The collateral obtained is based upon the assessed creditworthiness of the borrower. At March 31, 2012 and 2011, Trustmark had commitments to extend credit of $1.7 billion and $1.6 billion, respectively.

Standby and commercial letters of credit are conditional commitments issued by Trustmark to ensure the performance of a customer to a third party. When issuing letters of credit, Trustmark uses essentially the same policies regarding credit risk and collateral that are followed in the lending process. At March 31, 2012 and 2011, Trustmark’s maximum exposure to credit loss in the event of nonperformance by the other party for letters of credit was $161.7 million and $178.2 million, respectively. These amounts consist primarily of commitments with maturities of less than three years. Trustmark holds collateral to support certain letters of credit when deemed necessary.

Contractual Obligations

Payments due from Trustmark under specified long-term and certain other binding contractual obligations were scheduled in our Annual Report on Form 10-K for the year ended December 31, 2011. The most significant obligations, other than obligations under deposit contracts and short-term borrowings, were for operating leases for banking facilities. There have been no material changes since year-end.

At March 31, 2012, Trustmark’s total shareholders’ equity was $1.242 billion, an increase of $26.5 million from its level at December 31, 2011. During the first three months of 2012, shareholders’ equity increased primarily as a result of net income of $30.3 million and the $12.0 million of common stock issued in the Bay Bank acquisition, and was offset by common stock dividends of $14.9 million. Trustmark utilizes a capital model in order to provide Management with a monthly tool for analyzing changes in its strategic capital ratios. This allows Management to hold sufficient capital to provide for growth opportunities, protect the balance sheet against sudden adverse market conditions while maintaining an attractive return on equity to shareholders.

Regulatory Capital

Trustmark and TNB are subject to minimum capital requirements, which are administered by various federal regulatory agencies. These capital requirements, as defined by federal guidelines, involve quantitative and qualitative measures of assets, liabilities and certain off-balance sheet instruments. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional, discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements of Trustmark and TNB. Trustmark aims to exceed the well-capitalized guidelines for regulatory capital. As of March 31, 2012, Trustmark and TNB have exceeded all of the minimum capital standards for the parent company and its primary banking subsidiary as established by regulatory requirements. In addition, TNB has met applicable regulatory guidelines to be considered well-capitalized at March 31, 2012. To be categorized in this manner, TNB must maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios as set forth in the accompanying table. There are no significant conditions or events that have occurred since March 31, 2012, which Management believes have affected TNB's present classification.

In addition, during 2006, Trustmark enhanced its capital structure with the issuance of trust preferred securities and Subordinated Notes. For regulatory capital purposes, the trust preferred securities currently qualify as Tier 1 capital while the Subordinated Notes qualify as Tier 2 capital. The addition of these capital instruments provided Trustmark a cost effective manner in which to manage shareholders’ equity and enhance financial flexibility.

Dividends on Common Stock

Dividends per common share for the three months ended March 31, 2012 and 2011 were $0.23. Trustmark’s indicated dividend for 2012 is $0.92 per common share, which is the same as dividends per common share in 2011.

Liquidity

Liquidity is the ability to meet asset funding requirements and operational cash outflows in a timely manner, in sufficient amount and without excess cost. Consistent cash flows from operations and adequate capital provide internally generated liquidity. Furthermore, Management maintains funding capacity from a variety of external sources to meet daily funding needs, such as those required to meet deposit withdrawals, loan disbursements and security settlements. Liquidity strategy also includes the use of wholesale funding sources to provide for the seasonal fluctuations of deposit and loan demand and the cyclical fluctuations of the economy that impact the availability of funds. Management keeps excess funding capacity available to meet potential demands associated with adverse circumstances.

The asset side of the balance sheet provides liquidity primarily through maturities and cash flows from loans and securities, as well as the ability to sell certain loans and securities while the liability portion of the balance sheet provides liquidity primarily through noninterest and interest-bearing deposits. Trustmark utilizes federal funds purchased, brokered deposits, FHLB advances, securities sold under agreements to repurchase as well as the Federal Reserve Discount Window (Discount Window) to provide additional liquidity. Access to these additional sources represents Trustmark’s incremental borrowing capacity.

Deposit accounts represent Trustmark’s largest funding source. Average deposits totaled to $7.770 billion for the first three months of 2012 and represented approximately 79.7% of average liabilities and shareholders’ equity when compared to average deposits of $7.219 billion, which represented 75.9% of average liabilities and shareholders’ equity for the same time period in 2011.

Trustmark utilizes a limited amount of brokered deposits to supplement other wholesale funding sources. At March 31, 2012, brokered sweep Money Market Deposit Account (MMDA) deposits totaled $42.2 million compared to $42.1 million at December 31, 2011. At March 31, 2012, Trustmark had $49.8 million in term fixed-rate brokered CDs outstanding, compared with $49.7 million outstanding brokered CDs at December 31, 2011. The addition of brokered CDs during 2011 was part of an interest rate risk management strategy and represented the lowest cost alternative for term fixed-rate funding.

At March 31, 2012, Trustmark had $40.0 million of upstream federal funds purchased, compared to $365.0 million at December 31, 2011. Trustmark maintains adequate federal funds lines in excess of the amount utilized to provide sufficient short-term liquidity. Trustmark also maintains a relationship with the FHLB, which provided $2.3 million in advances at March 31, 2012, compared with $2.5 million in advances at December 31, 2011. Under the existing borrowing agreement, Trustmark had sufficient qualifying collateral to increase FHLB advances by $1.948 billion at March 31, 2012.

Additionally, Trustmark has the ability to enter into wholesale funding repurchase agreements as a source of borrowing by utilizing its unencumbered investment securities as collateral. At March 31, 2012, Trustmark had approximately $382.0 million available in repurchase agreement capacity compared to $603.0 million at December 31, 2011.

Another borrowing source is the Discount Window. At March 31, 2012, Trustmark had approximately $850.9 million available in collateral capacity at the Discount Window from pledges of loans and securities, compared with $777.4 million at December 31, 2011.

TNB has outstanding $50.0 million in aggregate principal amount of Subordinated Notes (the Notes) due December 15, 2016. At March 31, 2012, the carrying amount of the Notes was $49.8 million. The Notes were sold pursuant to the terms of regulations issued by the OCC and in reliance upon an exemption provided by the Securities Act of 1933, as amended. The Notes are unsecured and subordinate and junior in right of payment to TNB’s obligations to its depositors, its obligations under bankers’ acceptances and letters of credit, its obligations to any Federal Reserve Bank or the FDIC and its obligations to its other creditors, and to any rights acquired by the FDIC as a result of loans made by the FDIC to TNB.

During 2006, Trustmark completed a private placement of $60.0 million of trust preferred securities through a newly formed Delaware trust affiliate, Trustmark Preferred Capital Trust I, (the Trust). The trust preferred securities mature September 30, 2036 and are redeemable at Trustmark’s option beginning after five years. The proceeds from the sale of the trust preferred securities were used by the Trust to purchase $61.856 million in aggregate principal amount of Trustmark’s junior subordinated debentures. The net proceeds to Trustmark from the sale of the related junior subordinated debentures to the Trust were used to assist in financing Trustmark’s merger with Republic.

Another funding mechanism set into place in 2006 was Trustmark’s grant of a Class B banking license from the Cayman Islands Monetary Authority. Subsequently, Trustmark established a branch in the Cayman Islands through an agent bank. The branch was established as a mechanism to attract dollar denominated foreign deposits (i.e., Eurodollars) as an additional source of funding. At March 31, 2012, Trustmark had $81.9 million in Eurodollar deposits outstanding.

The Board of Directors currently has the authority to issue up to 20.0 million preferred shares with no par value. The ability to issue preferred shares in the future will provide Trustmark with additional financial and management flexibility for general corporate and acquisition purposes. At March 31, 2012, Trustmark has no shares of preferred stock issued.

Liquidity position and strategy are reviewed regularly by the Asset/Liability Committee and continuously adjusted in relationship to Trustmark’s overall strategy. Management believes that Trustmark has sufficient liquidity and capital resources to meet presently known cash flow requirements arising from ongoing business transactions.

Asset/Liability Management

Overview

Market risk reflects the potential risk of loss arising from adverse changes in interest rates and market prices. Trustmark has risk management policies to monitor and limit exposure to market risk. Trustmark’s primary market risk is interest rate risk created by core banking activities. Interest rate risk is the potential variability of the income generated by Trustmark’s financial products or services, which results from changes in various market interest rates. Market rate changes may take the form of absolute shifts, variances in the relationships between different rates and changes in the shape or slope of the interest rate term structure.

Management continually develops and applies cost-effective strategies to manage these risks. The Asset/Liability Committee sets the day-to-day operating guidelines, approves strategies affecting net interest income and coordinates activities within policy limits established by the Board of Directors. A key objective of the asset/liability management program is to quantify, monitor and manage interest rate risk and to assist Management in maintaining stability in the net interest margin under varying interest rate environments.

Derivatives

Trustmark uses financial derivatives for management of interest rate risk. The Asset/Liability Committee, in its oversight role for the management of interest rate risk, approves the use of derivatives in balance sheet hedging strategies. The most common derivatives employed by Trustmark are interest rate lock commitments, forward contracts, both futures contracts and options on futures contracts, interest rate swaps, interest rate caps and interest rate floors. In addition, Trustmark has entered into derivative contracts as counterparty to one or more customers in connection with loans extended to those customers. These transactions are designed to hedge exposures of the customers and are not entered into by Trustmark for speculative purposes. Increased federal regulation of the over-the-counter derivative markets may increase the cost to Trustmark to administer derivative programs.

As part of Trustmark’s risk management strategy in the mortgage banking area, various derivative instruments such as interest rate lock commitments and forward sales contracts are utilized. Rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified period of time. Trustmark’s obligations under forward contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. These derivative instruments are designated as fair value hedges under FASB ASC Topic 815, “Derivatives and Hedging.” The gross, notional amount of Trustmark’s off-balance sheet obligations under these derivative instruments totaled $441.7 million at March 31, 2012, with a positive valuation adjustment of $678 thousand, compared to $317.0 million, with a negative valuation adjustment of $1.5 million as of December 31, 2011.

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that offsets the changes in fair value of MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. Changes in the fair value of these exchange-traded derivative instruments are recorded in noninterest income in mortgage banking, net and are offset by the changes in the fair value of MSR. The MSR fair value represents the present value of future cash flows, which among other things includes decay and the effect of changes in interest rates. Ineffectiveness of hedging the MSR fair value is measured by comparing the change in value of hedge instruments to the change in the fair value of the MSR asset attributable to changes in interest rates and other market driven changes in valuation inputs and assumptions. The impact of this strategy resulted in a net negative ineffectiveness of $1.0 million and a net positive ineffectiveness of $263 thousand for the three months ended March 31, 2012 and 2011, respectively.

Trustmark offers certain derivatives products such as interest rate swaps directly to qualified commercial borrowers seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial borrowers by entering into offsetting interest rate swap transactions with third parties. Derivative transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded in noninterest income in bank card and other fees. Because the derivatives have mirror-image contractual terms, the changes in fair value substantially offset. In conjunction with the FASB’s fair value measurement guidance, Trustmark made an accounting policy election to measure the credit risk of these derivative financial instruments, which are subject to master netting agreements, on a net basis by counterparty portfolio. As of March 31, 2012, Trustmark had interest rate swaps with an aggregate notional amount of $94.4 million related to this program, compared to $71.2 million as of December 31, 2011. The fair value of these derivatives was immaterial at March 31, 2012 and December 31, 2011.

Market/Interest Rate Risk Management

The primary purpose in managing interest rate risk is to invest capital effectively and preserve the value created by the core banking business. This is accomplished through the development and implementation of lending, funding, pricing and hedging strategies designed to maximize net interest income performance under varying interest rate environments subject to specific liquidity and interest rate risk guidelines.

Financial simulation models are the primary tools used by Trustmark’s Asset/Liability Committee to measure interest rate exposure. Using a wide range of scenarios, Management is provided with extensive information on the potential impact to net interest income caused by changes in interest rates. Models are structured to simulate cash flows and accrual characteristics of Trustmark’s balance sheet. Assumptions are made about the direction and volatility of interest rates, the slope of the yield curve and the changing composition of Trustmark’s balance sheet, resulting from both strategic plans and customer behavior. In addition, the model incorporates Management’s assumptions and expectations regarding such factors as loan and deposit growth, pricing, prepayment speeds and spreads between interest rates.

Based on the results of the simulation models using static balances, it is estimated that net interest income may decrease 1.7% and 2.7% in a one-year, shocked, up 200 basis point rate shift scenario, compared to a base case, flat rate scenario at March 31, 2012 and 2011, respectively. In the event of a 100 basis point decrease in interest rates using static balances at March 31, 2012, it is estimated that net interest income may decrease by 4.8% compared to a 3.1% decrease at March 31, 2011. At March 31, 2012 and 2011, the impact of a 200 basis point drop scenario was not calculated due to the historically low interest rate environment.

The table below summarizes the effect various rate shift scenarios would have on net interest income at March 31, 2012 and 2011:

Interest Rate Exposure Analysis	Estimated Annual % Change
	in Net Interest Income
	2012			2011
Change in Interest Rates
+200 basis points		-1.7	%		-2.7	%
+100 basis points		-0.8	%		-1.7	%
-100 basis points		-4.8	%		-3.1	%

As shown in the table above, the interest rate shocks illustrate the negative contribution to net interest income in both rising and falling interest rate environments. While there are several factors that contribute to the decline in net interest income, the primary factor in a one-year, shocked, down 100 basis point rate shift scenario is an increased speed of prepayment of mortgage-related assets reinvested at lower interest rates, which is partially offset by lower deposit costs. In the one-year, shocked, up 200 basis point rate shift scenario, the principal factor for declining net interest income is an increased cost of deposits and other short-term liabilities. Although an increase in the rate on floating rate loans partially offsets the increased interest expense, the upward repricing is limited as many of these loans contain interest rate floors. Management cannot provide any assurance about the actual effect of changes in interest rates on net interest income. The estimates provided do not include the effects of possible strategic changes in the balances of various assets and liabilities throughout 2013 or additional actions Trustmark could undertake in response to changes in interest rates. Management will continue to prudently manage the balance sheet in an effort to control interest rate risk and maintain profitability over the long term.

Another component of interest rate risk management is measuring the economic value-at-risk for a given change in market interest rates. The economic value-at-risk may indicate risks associated with longer-term balance sheet items that may not affect net interest income at risk over shorter time periods. Trustmark also uses computer-modeling techniques to determine the present value of all asset and liability cash flows (both on- and off-balance sheet), adjusted for prepayment expectations, using a market discount rate. The economic value of equity (EVE), also known as net portfolio value, is defined as the difference between the present value of asset cash flows and the present value of liability cash flows. The resulting change in EVE in different market rate environments, from the base case scenario, is the amount of EVE at risk from those rate environments. As of March 31, 2012, the economic value of equity at risk for an instantaneous up 200 basis point shift in rates produced an increase in net portfolio value of 3.1%, compared to a net portfolio value decrease of 1.7% in March 31, 2011. An instantaneous 100 basis point decrease in interest rates produced a decline in net portfolio value of 6.5%, compared to a net portfolio value decrease of 4.3% at March 31, 2011. The following table summarizes the effect that various rate shifts would have on net portfolio value at March 31, 2012 and 2011:

Economic Value - at - Risk	Estimated % Change
	in Net Portfolio Value
	2012			2011
Change in Interest Rates
+200 basis points		3.1	%		-1.7	%
+100 basis points		3.3	%		0.2	%
-100 basis points		-6.5	%		-4.3	%
