Business Acquisition Fair Value and Expected Cash Flows Policy | Fair Value and Expected Cash Flows At the time of these acquisitions, the Company determined the fair value of the loan portfolios based on several assumptions. Factors considered in the valuations were projected cash flows for the loans, type of loan and related collateral, classification status, fixed or variable interest rate, term of loan, current discount rates and whether or not the loan was amortizing. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. Management also estimated the amount of credit losses that were expected to be realized for the loan portfolios. The discounted cash flow approach was used to value each pool of loans. For nonperforming loans, fair value was estimated by calculating the present value of the recoverable cash flows using a discount rate based on comparable corporate bond rates. This valuation of the acquired loans is a significant component leading to the valuation of the loss sharing assets recorded. The amount of the estimated cash flows expected to be received from the acquired loan pools in excess of the fair values recorded for the loan pools is referred to as the accretable yield. The accretable yield is recognized as interest income over the estimated lives of the loans. The Company continues to evaluate the fair value of the loans including cash flows expected to be collected. Increases in the Company’s cash flow expectations are recognized as increases to the accretable yield while decreases are recognized as impairments through the allowance for loan losses. During the years ended December 31, 2012 and 2011, increases in expected cash flows related to the acquired loan portfolios resulted in adjustments to the accretable yield to be spread over the estimated remaining lives of the loans on a level-yield basis. The increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements. This resulted in corresponding adjustments during the years ended December 31, 2012 and 2011, to the indemnification assets to be amortized on a level-yield basis over the remainder of the loss sharing agreements or the remaining expected lives of the loan pools, whichever is shorter. The amounts of these adjustments were as follows:
| Year Ended
| December 31, |  | December 31, |  | December 31,
| 2012 |  | 2011 |  | 2010
(In Thousands) |  |  |  |  |
Increase in accretable yield due to increased |  |  |  |  |
cash flow expectations | $42,567 |  | $27,069 |  | $58,951
Decrease in FDIC indemnification asset |  |  |  |  |
as a result of accretable yield increase | (34,054) |  | (23,821) |  | (51,888)
The adjustments, along with those made in previous years, impacted the Company’s Consolidated Statements of Income as follows:
| Year Ended

| 2012 |  | 2011 |  | 2010

Interest income | $36,186 |  | $49,208 |  | $19,452
Noninterest income | (29,864) |  | (43,835) |  | (17,134)
Net impact to pre-tax income | $6,322 |  | $5,373 |  | $2,318
Prior to January 1, 2010, the Company’s estimate of cash flows expected to be received from the acquired loan pools related to TeamBank and Vantus Bank had not materially changed, other than the adjustment of the provisional fair value measurements of the former TeamBank loan portfolio. On an on-going basis the Company estimates the cash flows expected to be collected from the acquired loan pools. For the loan pools acquired in 2012 and 2011, the cash flow estimates have increased during 2012. For the loan pools acquired in 2009, the cash flow estimates have increased, beginning with the fourth quarter of 2010, based on payment histories and reduced loss expectations of the loan pools. This resulted in increased income that was spread on a level-yield basis over the remaining expected lives of the loan pools. The loss sharing asset is measured separately from the loan portfolio because it is not contractually embedded in the loans and is not transferable with the loans should the Bank choose to dispose of them. Fair value was estimated using projected cash flows available for loss sharing based on the credit adjustments estimated for each loan pool (as discussed above) and the loss sharing percentages outlined in the Purchase and Assumption Agreement with the FDIC. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. The loss sharing asset is also separately measured from the related foreclosed real estate. The loss sharing agreement on the InterBank transaction includes a clawback provision whereby if credit loss performance is better than certain pre-established thresholds, then a portion of the monetary benefit is shared with the FDIC. The pre-established threshold for credit losses is $115.7 million for this transaction. The monetary benefit required to be paid to the FDIC under the clawback provision, if any, will occur shortly after the termination of the loss sharing agreement, which in the case of InterBank is 10 years from the acquisition date. At December 31, 2012, the Bank’s internal estimate of credit performance is expected to be better than the threshold set by the FDIC in the loss sharing agreement. Therefore, a separate clawback liability totaling $1.0 million was recorded at December 31, 2012. As changes in the fair values of the loans and foreclosed assets are determined due to changes in expected cash flows, changes in the amount of the clawback liability will occur.
