Employees who are not classified as HCE's (highly compensated employees) may contribute up to 30% of their salary; HCE's may contribute up to 6% of their salary. The Plan provides a discretionary company match which is determined annually. Currently, the Company matches 25% of the first 6% of compensation employees contribute to the plan. The employees vest in the employer contributions over a three-year period beginning on the employee's hire date. The expense incurred by the Company related to this plan was $6.0&amp;#160;million, $7.6&amp;#160;million and $8.2&amp;#160;million during the years ended December&amp;#160;31, 2010, 2011 and 2012, respectively.&lt;/font&gt;&lt;/p&gt;
