Compensation and Retirement Disclosure [Abstract] |
Employee Benefit Plans | Note 7. Employee Benefit Plans Defined Contribution Plan Substantially all employees meeting certain service requirements are eligible to participate in our 401(k) employee retirement plan. Employee contributions are limited to a percentage of their compensation, as defined in the plan. We make contributions based upon the greater of a percentage of employee contributions or ten percent of net income. Company contributions for 2013, 2012 and 2011 were $20.6 million, $16.9 million and $13.9 million, respectively. Deferred Compensation Plan We maintain a nonqualified deferred compensation plan for the benefit of certain eligible employees, including those whose contributions to the 401(k) employee retirement plan are limited due to provisions of the Internal Revenue Code. Participating employees may elect to defer receipt of a percentage of their compensation, as defined in the plan, and the deferred amount is credited to each participant’s deferred compensation account. The plan is not funded and the Company does not make a matching contribution to this plan. Although the plan is not funded, participants are allowed to select investment options for which their deferrals and future earnings are deemed to be invested. Participant accounts are adjusted daily to reflect participant deferrals and the performance of their deemed investments. The amounts owed to the participants totaled $36.6 million and $30.0 million at December 31, 2013 and 2012, respectively.
