EMPLOYEE BENEFIT PLANS | 18. EMPLOYEE BENEFIT PLANS Retirement Savings and Profit Sharing Plan We maintain a defined contribution 401(k) retirement savings plan covering substantially all of our employees in the United States. Under the plan, an eligible employee may elect to defer receipt of a portion of the annual pay, including salary and bonus. During 2012, we contributed this amount to the plan on the employee’s behalf and also made a matching contribution equal to 100% of the first 2% and 50% of the next 4% of the percentage of annual pay that the employee elected to defer. A participant is 100% vested at all times in the amounts the employee defers from annual pay. A participant becomes 100% vested in our matching contributions after two years of credited employee service. During the years ended December 31, 2012, 2011 and 2010, we recorded expense for continuing and discontinued operations under this plan of approximately $11.9 million, $12.8 million, and $11.5 million, respectively, net of any forfeited employer matching contributions. Employee Stock Purchase Plan We maintain an employee stock purchase plan that allows substantially all full-time and part-time employees to acquire shares of our common stock through payroll deductions over three-month offering periods. The per share purchase price is equal to 95% of the fair market value of a share of our common stock on the last day of the offering period, and purchases are limited to 10% of an employee’s salary, up to a maximum of $25,000 per calendar year. We are authorized to grant up to 4.0 million shares of common stock under the employee stock purchase plan, and, as of December 31, 2012, 2.6 million shares of common stock have been issued under the plan. Share-based compensation expense recorded during the years ended December 31, 2012, 2011 and 2010, in connection with the compensatory elements of our employee stock purchase plan, was not significant.
