5. Employee Benefit Plans

GII and the Company’s other U.S.-based subsidiaries sponsor a defined contribution employee retirement plan under which their employees may contribute up to 50% of their annual compensation subject to Internal Revenue Code maximum limitations and to which the subsidiaries contribute a specified percentage of each participant’s annual compensation up to certain limits as defined in the retirement plan. Additionally, GEL has a defined contribution plan under which its employees may contribute up to 7.5% of their annual compensation. In both the plans described above, the subsidiaries contribute an amount determined annually at the discretion of the Board of Directors. During the years ended December 28, 2013, December 29, 2012, and December 31, 2011, expense related to these plans of $26,839, $22,159, and $20,647, respectively, was charged to operations.

Certain of the Company’s foreign subsidiaries participate in local defined benefit pension plans. Contributions are calculated by formulas that consider final pensionable salaries. Neither obligations nor contributions for the years ended December 28, 2013, December 29, 2012, and December 31, 2011, were significant.
