The Company's intangible assets with definite useful lives are amortized either based on the pattern in which the economic benefits of the intangible asset are expected to be consumed or using the straight-line method over their estimated useful lives, which range from three to fifteen years. Amortization of intangible assets was $1.2 million and $1.6 million for the years ended December 31, 2015 and 2014, respectively. The estimated aggregate future amortization expense of all intangible assets is $1.2 million for 2016, $1.0 million for 2017, $1.0 million for 2018, $0.8 million for 2019 and $0.7 million for 2020.
The insurance licenses and trade name intangible assets have indefinite useful lives and are not amortized. All intangible assets with indefinite useful lives are reviewed annually by the Company for impairment. No impairment charges were taken on intangible assets in 2015 or 2014.
