Employee Benefit Plans

NOTE 9 — Employee Benefit Plans

Our U.S. employees are generally eligible to participate in a retirement and savings plan that qualifies under Section 401(k) of the Internal Revenue Code. Participating employees may contribute up to 50% of their pretax salary, but not more than statutory limits. We contribute fifty cents for each dollar a participant contributes in this plan, with a maximum contribution of 3% of a participant's earnings. Our contribution vests with the employee after the employee completes two years of service. Participating employees have the option to invest in our common stock, but there is no requirement for participating employees to invest their contribution or our matching contribution in our common stock. We also have various defined contribution plans for our international employees. Our contributions to these benefit plans were $18 million, $12 million and $10 million for the years ended December 31, 2011, 2010 and 2009.
