FDIC Assisted Transaction Description

Also in connection with the FDIC assisted acquisition, the Bank agreed to make a true-up payment, also known as a clawback liability or clawback provision, to the FDIC on the date that is 45 days following the last day (such day, the “True-Up Measurement Date”) of the final shared-loss month, or upon the final disposition of all covered assets under the shared-loss agreements in the event losses thereunder fail to reach expected levels. Under the shared-loss agreements, the Bank will pay to the FDIC 50% of the excess, if any, of: (i) 20% of the Intrinsic Loss Estimate of $906.0 million (or $181.2 million) (as determined by the FDIC) less (ii) the sum of: (A) 25% of the asset premium (discount) of ($227.5 million) (or ($56.9 million)); plus (B) 25% of the cumulative shared-loss payments (defined as the aggregate of all of the payments made or payable to the Bank minus the aggregate of all of the payments made or payable to the FDIC); plus (C) the sum of the period servicing amounts for every consecutive twelve-month period prior to and ending on the True-Up Measurement Date in respect of each of the shared-loss agreements during which the shared-loss provisions of the applicable shared-loss agreement is in effect (defined as the product of the simple average of the principal amount of shared-loss loans and shared-loss assets at the beginning and end of such period times 1%). The true-up payment represents an estimated liability of $24.4 million and $22.0 million, net of discount, as of September 30, 2015 and December 31, 2014, respectively.
