Restructuring [Abstract]

Restructuring

Note 14.    Restructuring

In an effort to consolidate our operations, streamline product offerings, and align our manufacturing operations with current business conditions, we have implemented various restructuring plans from 2001 through 2006. All restructuring activity presented below is related to the Semiconductor Group.

Adjustments of prior restructuring costs relate to changes in estimated sublease income over the remaining lease term for facility exit activities recorded in prior years and include normal accretion.

As of December 31, 2011, our restructuring plans had been completed except for payments of future rent obligations which we estimate will be paid in cash through 2017.

The following table summarizes our restructuring activity:

	December 31,
	2011			2010
	(In thousands)
Balance, beginning of period	$	14,865		$	18,046
Cash payments for rent obligations		(4,423	)		(4,554	)
Adjustment of prior restructuring costs		(464	)		1,373
Balance, end of period	$	9,978		$	14,865
