FDIC Indemnification Asset [Abstract] |
FDIC Indemnification Asset | Note 7 – FDIC Indemnification Asset On April 15, 2011, the Mississippi Department of Banking and Consumer Finance closed the Heritage Banking Group (Heritage) and appointed the FDIC as receiver. On the same date, Trustmark National Bank (TNB), Trustmark’s principal subsidiary, entered into a purchase and assumption agreement with the FDIC in which TNB agreed to assume all of the deposits and purchase essentially all of the assets of Heritage. The FDIC and TNB also entered into a loss-share agreement covering substantially all loans and all other real estate acquired. Under the loss-share agreement, the FDIC will cover 80% of covered loan and other real estate losses incurred. Pursuant to the provisions of the loss-share agreement, TNB may be required to make a true-up payment to the FDIC at the termination of the loss-share agreement should actual losses be less than certain thresholds established in the agreement. TNB calculates the projected true-up payable to the FDIC quarterly and records a FDIC true-up provision for the present value of the projected true-up payable to the FDIC at the termination of the loss-share agreement. TNB’s FDIC true-up provision totaled $2.4 million and $2.1 million at June 30, 2015 and December 31, 2014, respectively. Trustmark periodically re-estimates the expected cash flows on the acquired covered loans as required by FASB ASC Topic 310-30. For the first six months of 2015 and 2014, this analysis resulted in improvements in the estimated future cash flows of the acquired covered loans that remain outstanding as well as lower expected remaining losses on those loans, primarily due to pay-offs of acquired covered loans. The pay-offs and improvements in the estimated expected cash flows of the acquired covered loans resulted in a reduction of the expected loss-share receivable from the FDIC. Reductions of the FDIC indemnification asset resulting from improvements in expected cash flows and covered losses based on the re-estimation of acquired covered loans are amortized over the lesser of the remaining life or contractual period of the acquired covered loan as a yield adjustment consistent with the associated acquired covered loan. Other noninterest income for the first six months of 2015 and 2014 included $844 thousand and $1.1 million, respectively, of amortization of the FDIC indemnification asset. Amortization of the FDIC indemnification asset resulted from improvements in the expected cash flows and lower loss expectations. During the first six months of 2015 and 2014, other noninterest income included a reduction of the FDIC indemnification asset of $1.3 million and $561 thousand, respectively, primarily resulting from loan pay-offs partially offset by loan pools of acquired covered loans with increased loss expectations. Noninterest income also included a reduction of the FDIC indemnification asset of $621 thousand during the first six months of 2015 due to sales and valuation adjustments of covered other real estate. For the periods presented, changes in the FDIC indemnification asset were as follows ($ in thousands):
