Employee Benefits

The Company maintains closed, defined-benefit pension and postretirement medical plans. QEP's pension plans include a qualified and a nonqualified retirement plan. The Company's postretirement medical plan is unfunded and provides certain health care and life insurance benefits for certain retired employees. During the three months ended March 31, 2014, the Company made contributions of $2.7 million to its funded qualified pension plan, and $0.9 million to its unfunded nonqualified retirement plan. Contributions to funded qualified plans increase plan assets while contributions to unfunded nonqualified plans are used to fund current benefit payments. During the remainder of 2014, the Company expects to contribute approximately $5.4 million to its funded qualified pension plan, $4.0 million to its unfunded nonqualified pension plans and approximately $0.2 million for retiree health care and life insurance benefits.
