PORTFOLIO LOANS COVERED BY LOSS SHARE ("Covered loans")

Purchased loans acquired in a business combination, including loans purchased in our FDIC-assisted transactions, are recorded at estimated fair value on their purchase date without a carryover of the related allowance for loan losses. Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include factors such as past due and non-accrual status. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the non-accretable yield. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges or a reclassification of the difference from non-accretable to accretable with a positive impact on interest income, prospectively. Further, any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. Acquired loans that have common risk characteristics are aggregated into pools. The Company updates its cash flow projections for credit-impaired acquired loans, including loans acquired from the FDIC, on a quarterly basis. Assumptions utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration analysis. The loan migration analysis is a matrix of probability that specifies the probability of a loan pool transitioning into a particular delinquency or liquidation state given its current state at the remeasurement date. Loss severity factors are based upon industry data.

Covered loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not always a clear indicator of the Company's losses on acquired loans as a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.

The accretable yield is accreted into interest income over the estimated life of the acquired loans using the effective

yield method.

Changes in the accretable yield for purchased loans were as follows for the three months ended March 31, 2013, and 2012:



(in thousands)	March 31, 2013			March 31, 2012

Other changes in the accretable yield include the impact of cash flow timing estimates, changes in variable interest rates, and other non-credit related adjustments. For the three months ended March 31, 2013 and 2012, the Company received payments of $1.7 million and $11.6 million, respectively, for loss share claims under the terms of the FDIC shared-loss agreements.

Due to continued favorable projections in the expected cash flows of its Covered loans, the Company continues to anticipate that it will be required to pay the FDIC at the end of one of the loss share agreements. Accordingly, a liability of $879,000 has been recorded at March 31, 2013. As part of the remeasurement process, the Company recorded a $304,000 adjustment to increase the liability through Other noninterest expense during the quarter ended March 31, 2013. The liability will continue to be adjusted as part of the quarterly remeasurement process through the end of the loss share agreement.
