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 non-performing 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, 2017, 2016 and 2015, improvements 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, when applicable, until they were terminated or expired. This resulted in corresponding adjustments during the years ended December 31, 2017, 2016 and 2015, to the indemnification assets (which have now been reduced to $-0- due to the termination of the loss sharing agreements). The amounts of these adjustments were as follows:
