(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.

(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.

(2)	Accretable yield on loans acquired from Bay Bank on March 16, 2012.

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

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):

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.

The following table provides an aging analysis of contractually past due and nonaccrual acquired loans, by class at March 31, 2012 and December 31, 2011 ($ in thousands):
