Intangible asset amortization expense totaled $50.8 million, $51.1 million and $50.9 million for the years ended March 31, 2014, 2013 and 2012, respectively. The Company expects to recognize amortization expense on the intangible assets subject to amortization of $52.0 million in fiscal years 2015 and 2016, $32.9 million in fiscal year 2017, $22.4 million in fiscal year 2018, and $22.2 million in fiscal year 2019. During the third quarter of fiscal 2014, the Company completed the testing of indefinite lived intangible assets (tradenames) and goodwill for impairment in accordance with ASC 350, Intangibles-Goodwill and Other. The fair value of the Company's indefinite lived intangible assets and reporting units were primarily estimated using an income valuation model (discounted cash flow) and market approach (guideline public company comparables), which indicated that the fair value of the Company's indefinite lived intangible assets and reporting units exceeded their carrying value; therefore, no impairment was present. Total cumulative goodwill impairment charges recorded in historical periods were $319.3 million at March 31, 2014 and March 31, 2013, all of which were incurred in fiscal 2009. |
