Goodwill and Intangible Assets Disclosure [Abstract]

The changes in the carrying amount of goodwill are as follows (in thousands):



	Goodwill
Balance as of September 30, 2011	$	663,041
Goodwill recognized through business combinations (Note 3)	133,958
Goodwill adjustments	3,514
Goodwill as of September 28, 2012	$	800,513

The increase in goodwill for the fiscal year ended September 28, 2012 resulted primarily from the acquisition of AATI as discussed in Note 3, Business Combinations in these Notes to the Consolidated Financial Statements. In addition, the Company recorded the final measurement period adjustment related to the acquisition of SiGe which resulted in an increase to goodwill.

The Company tests its goodwill and non-amortizing trademarks for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if certain events occur indicating the carrying value of goodwill or non-amortizing trademarks may be impaired. There were no indicators of impairment noted during the fiscal year ended September 28, 2012. However, based on the results of our annual testing, the Company determined that one of its non-amortizing trademarks did in fact have a finite life and accordingly the asset was reclassified and will be amortized over its estimated useful life as of September 28, 2012.

Intangible assets consist of the following (in thousands):
