Goodwill

The table below illustrates goodwill by segment for the years ended December 31, 2016 and 2015 ($ in thousands):

	General
	Banking		Insurance		Total
Balance as of January 1, 2015	$	321,132	$	44,368	$	365,500
Goodwill from purchase of insurance book of business during 2015		—		656		656

The Insurance segment includes TNB’s wholly-owned retail insurance subsidiary that offers a diverse mix of insurance products and services. During 2015, Trustmark purchased an insurance book of business that increased goodwill $656 thousand for the Insurance segment. Trustmark performed goodwill impairment tests for the General Banking and Insurance segments during 2016, 2015 and 2014. Based on these tests, Trustmark concluded that the fair value of both the General Banking and Insurance segments substantially exceeded the book value and no impairment charge was required.

Trustmark recorded $6.9 million of amortization of identifiable intangible assets in 2016, $7.8 million in 2015 and $8.8 million in 2014. Trustmark estimates that amortization expense for identifiable intangible assets will be $5.9 million in 2017, $4.9 million in 2018, $3.8 million in 2019, $2.5 million in 2020 and $1.7 million in 2021. 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 2016, 2015 or 2014.

The following table illustrates the carrying amounts and remaining weighted-average amortization periods of identifiable intangible assets as of December 31, 2016 ($ in thousands):
