Goodwill

There were no changes in the carrying amount of goodwill during 2017 and 2016. Goodwill is reviewed annually for impairment and more frequently if potential impairment indicators exist. No impairment indicators were identified during 2017 and 2016. All of the Company's goodwill is associated with the Property and Casualty business segment (See Note 21. Segment Information for additional information on the reportable business segment).

Other intangible assets amortization expense was $5.4 million, $6.1 million, and $6.0 million for the years ended December 31, 2017, 2016, and 2015, respectively. None of the intangible assets with definite useful lives are anticipated to have a residual value.
