The amortization of finite-lived intangibles is computed using the straight-line method except for customer relationships which are computed using an accelerated method. Estimated lives of finite-lived intangibles range from two to ten years. Total amortization expense for the three month periods ended March 31, 2012 and April 2, 2011 was $0.8 million and $0.4 million.

In the three month period ended March 31, 2012, the Company recorded a $0.6 million reduction in the fair value of royalty payments to RTM with a corresponding decrease of $0.4 million to goodwill and $0.2 million to intangible assets. See Note 4 for a summary of the acquisition and goodwill impairment analysis.
