	RETIREMENT PLANS

Defined benefit pension plans — We sponsor a qualified defined benefit pension plan covering substantially all full-time employees hired prior to January 1, 2011. Participants will no longer accrue benefits under this plan effective December 31, 2015. We also sponsor an unfunded supplemental executive retirement plan, which provides certain employees additional pension benefits and was closed to new participants effective January 1, 2007. Benefits under both plans are based on the employees’ years of service and compensation over defined periods of employment.

Postretirement healthcare plans — We also sponsor healthcare plans that provide postretirement medical benefits to certain employees who meet minimum age and service requirements. The plans are contributory, with retiree contributions adjusted annually, and contain other cost-sharing features such as deductibles and coinsurance.

Future cash flows — Our policy is to fund our plans at or above the minimum required by law. As of the date of our last actuarial funding valuation, there was no minimum contribution funding requirement. Details regarding fiscal 2013 contributions are as follows (in thousands):

We will continue to evaluate contributions to our funded defined benefit pension plan based on changes in pension assets as a result of asset performance in the current market and economic environment.
