Employee Benefit Plans |
Employee Benefit Plans | 11. Employee Benefit Plans We and certain of our subsidiaries sponsor various retirement plans for most full-time and some part-time employees. These plans primarily consist of defined contribution plans. The defined contribution plans generally provide for contributions up to 2.5% of covered employees' salaries or wages. These contributions totaled $5.2 million in 2012, $5.1 million in 2011 and $4.3 million in 2010. Of these amounts, approximately $0.1 million was payable to the plans at December 31, 2012 and 2011. Certain of our subsidiaries also participate or have participated in various multi-employer pension plans for the benefit of employees who are union members. As of December 31, 2012 and 2011, we had 5 and 7 employees, respectively, who were union members. There were no contributions made to multi-employer pension plans in 2012, 2011 or 2010. The data available from administrators of other multi-employer pension plans is not sufficient to determine the accumulated benefit obligations, nor the net assets attributable to the multi-employer plans in which our employees participate or previously participated. Certain individuals at one of our operations are entitled to receive fixed annual payments that reach a maximum amount, as specified in the related agreements, for a 15 year period following retirement or, in some cases, the attainment of 65 years of age. We recognize the unfunded status of the plan as a non-current liability in our Consolidated Balance Sheet. Benefits vest 50% after ten years of service, 75% after fifteen years of service and are fully vested after 20 years of service. We had an unfunded benefit liability of $3.0 million and $2.8 million recorded as of December 31, 2012 and 2011, respectively.
