Employee Benefit Plans

Defined Contribution Plan

We have one qualified 401(k) plan covering all eligible employees. Under the plan, employees may contribute up to the statutory allowable amount for any calendar year. We make matching contributions equal to:

• $1.00 for each dollar contributed up to the first 4% of an individual’s base salary and incentive cash bonus; and

• $0.50 for each dollar contributed of the next 2% of such compensation.

For the three months ended September 30, 2012, and 2011, we recorded matching contributions of approximately $798, and $601, respectively. For the nine months endedSeptember 30, 2012, and 2011, we recorded matching contributions of approximately $2,853 and $2,206, respectively.

Defined Benefit Plans

We maintain defined benefit plans for employees in certain countries outside the United States, including retirement benefit plans required by applicable local law. The plans are valued by independent actuaries using the projected unit credit method. The liabilities correspond to the projected benefit obligations of which the discounted net present value is calculated based on years of employment, expected salary increases, and pension adjustments.

The components of net periodic benefit cost are as follows:
