Retirement Savings Plans

11. Retirement Savings Plans

U.S. Based Employees

We have an employee savings and retirement plan (the “401(K) Plan”). The 401(K) Plan is intended to be a tax-qualified plan covering substantially all U.S.-based employees. Under the terms of the 401(K) Plan, employees may elect to contribute up to 20% of their compensation, or the statutory prescribed limit, if less. We may, at our discretion, match employee contributions up to a maximum of 4% of the employee’s compensation. Employer matching contributions totaled $1.8 million, $1.7 million and $1.3 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Non-U.S. Based Employees

We provide retirement benefits for employees located outside the U.S. commensurate with other similar companies in those respective locations. Employer contributions, in the form of cash, totaled $1.5 million, $1.2 million and $1.1 million for the years ended December 31, 2013, 2012 and 2011, respectively.
