Trustmark's General Banking segment delivers a full range of banking services to consumer, corporate, small and middle-market businesses through its extensive branch network.  During 2013, Trustmark recorded as goodwill $81.6 million from its merger with BancTrust and $150 thousand from its acquisition of two SOUTHBank branches.  During 2014, Trustmark recorded a measurement period adjustment that decreased goodwill $7.4 million as a result of fair value adjustments to BancTrust’s assets and liabilities.

The Insurance segment includes TNB’s wholly-owned retail insurance subsidiary that offers a diverse mix of insurance products and services.  Trustmark performed an impairment test of goodwill of reporting units in both the General Banking and Insurance segments during 2014, 2013 and 2012, which indicated that no impairment charge was required.  Based on this analysis, Trustmark concluded that no impairment charge was required.

In both 2014 and 2013, Trustmark recorded $8.8 million of amortization of identifiable intangible assets and recorded $3.8 million in 2012.  Trustmark estimates that amortization expense for identifiable intangible assets will be $7.6 million in 2015, $6.7 million in 2016, $5.7 million in 2017, $4.8 million in 2018 and $3.6 million in 2019.  Fully amortized intangibles are excluded from the table above.  Trustmark continually evaluates whether events and circumstances have occurred that indicate that identifiable intangible assets have become impaired.  Measurement of any impairment of such identifiable intangible assets is based on the fair values of those assets.  There were no impairment losses on identifiable intangible assets recorded during 2014, 2013 or 2012.
