Amortization expense was $16.6 million, $16.0 million, and $15.3 million, for the years ended December 31, 2015, 2014, and 2013, respectively. The Company cannot reliably determine the pattern for which it consumes the benefit of its customer relationship intangible assets. As such, the Company amortizes its customer relationship intangible assets using the straight‑line method over the estimated lives based upon the Company’s historical customer retention and recurring revenue base.

The estimated remaining amortization expense related to intangible assets with finite lives for each of the five succeeding years and thereafter is as follows at December 31, 2015:
