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 October 1, 2011 and October 2, 2010 was $0.3 million and $0.4 million, respectively, and for the nine month periods ended October 1, 2011 and October 2, 2010 was $1.1 million and $1.2 million, respectively.

The estimated future amortization expense as of October 1, 2011 is as follows (in thousands):

2011 (remaining three months)	$	319
2012	1,264
2013	1,095
2014	752
2015	632
2016	362
