Developed technology is amortized on a straight line basis over 10 to 20 years, depending on the life of the product technology.  Intangible assets related to customer relationships are generally amortized over a period of up to 10 years on an accelerated basis.  In-process research and development is amortized on a straight line basis over the product’s estimated useful life upon completion of the technology.  Other intangible assets include acquired backlog, product trademarks and trade names, non-competition agreements and defensible assets.  With the exception of product trademarks and trade names, such assets are amortized on a straight line basis over a period of three months to 10 years, depending on the asset.  Trademarks and trade names associated with products are amortized on a straight line basis over the estimated remaining life of the product technology, which ranges from 10 to 20 years.  Trademarks and trade names associated with a business have indefinite lives and are not amortized.

Amortization expense related to intangible assets totaled $2.6 million for the three months ended March 30, 2013 and $5.2 million for the three months ended March 31, 2012.

Estimated aggregate amortization expense for future fiscal years is as follows:

(In thousands)	Estimated Aggregate Amortization Expense
2013 (remaining)	$	7,751
2014	8,344
2015	6,712
2016	6,337
2017	5,371
Thereafter	19,863
	$	54,378

The Company has excluded $2.0 million of amortization expense related to certain in-process research and development projects from the table above, as it was uncertain as of March 30, 2013 when the technology will be completed and when the amortization will begin.
