In accordance with ASC Topic 350, "Intangibles—Goodwill and Other," goodwill is not subject to amortization, but is monitored at least annually for impairment, or more frequently, as necessary, if events or circumstances exist that would more likely than not reduce the fair value of the reporting unit below its carrying amount. For the Company's annual goodwill impairment analysis, the Company operates under one reporting unit. The Company completed the annual impairment test required as of fiscal 2011 and determined that there was no impairment. At the time of the annual test, the entity-wide estimated fair value exceeded the net book value by approximately 25%.

Late in the second quarter of fiscal 2012, the Company's stock price experienced a decline. In the third quarter of fiscal 2012, the Company's stock price improved but remained below the price levels experienced in fiscal 2011 and the first five months of fiscal 2012. The Company did not record any impairment losses related to goodwill or intangible assets during the fiscal year to date period ended September 29, 2012 as the stock price decline was not deemed to be more than temporary and there were no other events or circumstances that would more likely than not reduce the fair value of the reporting unit below its carrying amount. In the fourth quarter of fiscal 2012, the Company will conduct its annual impairment test of goodwill. Due to the recent decline in its stock price, the Company may be required to record an impairment of goodwill in the fourth quarter of fiscal 2012 as a result of the test. A non-cash goodwill impairment charge would have the effect of decreasing the Company's earnings in such period. If the Company is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.

The changes in the carrying amount of goodwill for the fiscal year to date period ended September 29, 2012 are as follows (in thousands):


Balance at December 31, 2011	$	140,654
Goodwill adjustments related to sale of practice		(29	)
Effect of foreign currency translation adjustments		1,758
