For fiscal years ended March 31, 2015, 2014 and 2013 amortization related to intangibles was $2.1 million, $2.1 million and $2.3 million, respectively. The weighted-average useful life of amortized intangibles was 16 years in the fiscal years ended March 31, 2015 and 2014. The weighted-average period prior to the next renewal for patents was 2.5 years and 3.5 years in the fiscal years ended March 31, 2015 and 2014, respectively. No other intangible classes have renewal or extension periods. Estimated amortization of intangible assets for the each of the next five fiscal years is $2.1 million and, thereafter, amortization will total $15.6 million.

For fiscal year 2015, the Company completed its impairment test on goodwill and intangible assets with indefinite useful lives as of January 1, 2015 and concluded that goodwill and indefinite-lived assets were not impaired.

In fiscal year 2013, the Company's annual goodwill and other indefinite-lived intangible asset impairment test resulted in a $1.1 million goodwill impairment charge, which represented all of the goodwill related to the KEMET Foil Manufacturing, LLC ("KEMET Foil") reporting unit due to reduced earnings and cash flows caused by macro-economic factors and excess capacity in our industry.
