On September 15, 2015, the Company entered into an agreement with the FDIC to terminate all loss share agreements which were entered into in 2010 and 2012 in conjunction with the Company’s acquisition of substantially all of the assets (“covered assets”) and assumption of substantially all of the liabilities of four failed banks in FDIC-assisted transactions. Under the early termination, all rights and obligations of the Company and the FDIC under the FDIC loss share agreements, including the clawback provisions and the settlement of loss share and expense reimbursement claims, have been resolved and terminated. Under the terms of the agreement, the FDIC made a net payment of $2,368,000 to Simmons Bank as consideration for the early termination of the loss share agreements. The early termination was recorded in the Company’s financial statements by removing the FDIC Indemnification Asset, receivable from FDIC, the FDIC True-up liability and recording a one -time, pre-tax charge of $7,476,000. As a result, the Company reclassified loans previously covered by FDIC loss share to loans acquired, not covered by FDIC loss share. Foreclosed assets previously covered by FDIC loss share were reclassified to foreclosed assets not covered by FDIC loss share. The following table reflects the carrying value of all loans acquired as of December 31, 2017 and 2016:

Loans acquired were individually evaluated and recorded at estimated fair value, including estimated credit losses, at the time of acquisition. These loans are systematically reviewed by the Company to determine the risk of losses that may exceed those identified at the time of the acquisition. Techniques used in determining risk of loss are similar to the Company’s legacy loan portfolio, with most focus being placed on those loans which include the larger loan relationships and those loans which exhibit higher risk characteristics.

In addition to the accretable yield on acquired loans not considered to be impaired, the amount of the estimated cash flows expected to be received from the purchased credit impaired loans in excess of the fair values recorded for the purchased credit impaired loans is referred to as the accretable yield. The accretable yield is recognized as interest income over the estimated lives of the loans. Each quarter, the Company estimates the cash flows expected to be collected from the acquired purchased credit impaired loans, and adjustments may or may not be required. This has resulted in an increase in interest income that is spread on a level-yield basis over the remaining expected lives of the loans. For those loans previously covered by FDIC loss share, the increases in expected cash flows also reduced the amount of expected reimbursements under the loss sharing agreements with the FDIC, which was recorded as indemnification assets. The estimated adjustments to the indemnification assets were amortized on a level-yield basis over the remainder of the loss-sharing agreements or the remaining expected lives of the loans, whichever was shorter. Because the Company’s loss share agreements with the FDIC have been terminated, there will be no further indemnification asset amortization in future quarters. The impact of these adjustments on the Company’s financial results for the years ended December 31, 2017, 2016 and 2015 is shown below:

| ( 1 ) | Negative non-interest income resulted from the amortization of the FDIC indemnification assets. Because the Company’s loss share agreements with the FDIC have been terminated, there will be no further indemnification asset amortization.
These adjustments will be recognized over the remaining lives of the purchased credit impaired loans. The accretable yield adjustments recorded in future periods will change as the Company continues to evaluate expected cash flows from the purchased credit impaired loans. Changes in the carrying amount of the accretable yield for all purchased impaired loans were as follows for the years ended December 31, 2017, 2016 and 2015.

Purchased impaired loans are evaluated on an individual borrower basis. Because some loans evaluated by the Company were determined to have experienced impairment in the estimated credit quality or cash flows, the Company recorded a provision and established an allowance for loan losses for loans acquired resulting in a total allowance on loans acquired of $418,000 at December 31, 2017 and $954,000 at December 31, 2016 and 2015. The purchase and assumption agreements for the FDIC-assisted acquisitions allowed for the FDIC to recover a portion of the funds previously paid out under the indemnification agreement in the event losses failed to reach the expected loss level under a claw back provision (“true-up provision”). The amount of the true-up provision for each acquisition was measured and recorded at Day 1 fair values. It was calculated as the difference between management’s estimated losses on covered loans and covered foreclosed assets and the loss threshold contained in each loss share agreement, multiplied by the applicable clawback provisions contained in each loss share agreement, then discounted back to net present value. Under the terms of the loss share termination agreement, the FDIC made a net payment of $2.4 million to Simmons Bank as consideration for early termination. The early termination was recorded in the Company’s financial statements by removing the FDIC indemnification asset, receivable from FDIC, the FDIC true-up provision and recording a one -time, pre-tax charge of $7.5 million. The following table presents a summary of the changes in the FDIC true-up provision for the year ended December 31, 2015 which were included in other assets on the balance sheet. Due to the termination of the FDIC agreements in September 2015 there was no amortization expense recorded for the years ended December 31, 2017 and 2016.
