Employee Benefit Plans

In the periods presented, certain employees of Con-way and its subsidiaries in the U.S. were covered under several retirement benefit plans, including defined benefit pension plans, defined contribution retirement plans and a postretirement medical plan. See Note 9, “Employee Benefit Plans,” of Item 8, “Financial Statements and Supplementary Data,” in Con-way’s 2013 Annual Report on Form 10-K for additional information concerning its employee benefit plans.

Defined Benefit Pension Plans

As a result of plan amendments in previous years, no additional benefits accrue under these plans and already-accrued benefits will not be adjusted for future increases in compensation. The following table summarizes the components of net periodic benefit expense (income) for Con-way’s domestic defined benefit pension plans:
