Employee Benefit Plans

The Company has a qualified retirement plan under the provisions of Section 401(k) of the Internal Revenue Code covering substantially all employees in the U.S. Participants in this plan may defer up to the maximum annual amount allowable under IRS regulations. Company contributions to the 401(k) Plan were as follows:



	Year ended December 31,
	2011		2010		2009
401(k) Plan contributions	$	4,953	$	4,053	$	3,426

During the fourth quarter of 2004, the Company’s Board of Directors approved a non-qualified deferred compensation plan (the “Compensation Plan”). Under the Compensation Plan, employees who are eligible to participate and members of the Board of Directors, are provided with the opportunity to defer a specified percentage of their cash compensation which the Company will be obligated to deliver on a future date. At the time of deferral, the Company allocates the deferred monies to a trust account that is invested at the participants’ election. The amount of compensation to be deferred by each participating employee or board member will be based on elections by each participant and adjusted for any positive or negative investment results from investment alternatives selected by the participant under the Compensation Plan. The liability for the deferred compensation and the value of the funds allocated to the trust by the Company are included on the Company's consolidated balance sheets as follows:



	December 31, 2011		December 31, 2010
Other non-current assets, net:
Compensation plan funds	$	3,635	$	2,971
Other long-term liabilities:
Deferred compensation	$	3,635	$	2,971

The Company also has a pension obligation related to its German subsidiary, acquired as a result of the Company’s purchase of the Infineon Technologies AG, GaAs business in 2002. The pension liability becomes payable when the covered employees reach the age of 60 or 65 and the Company has elected to secure the liability through a reinsurance program paid for by the Company. The Company has included the obligation to deliver the pension obligation in the “Other long-term liabilities” line item on its consolidated balance sheets and the insurance receivables in the “Other noncurrent assets, net.” The value of the pension obligation at December 31, 2011 and 2010 was $3,217 and $2,793, respectively. The value of the insurance receivable at December 31, 2011 and 2010 was $3,277 and $3,193, respectively. Additional disclosures have not been included due to the insignificance of the plan.
