Defined benefit plans [Abstract]

Defined benefit plans

(6) Defined benefit plans

We maintain defined benefit pension plans for certain U.S. and non-U.S. employees.  The benefits under our domestic defined benefit plan were frozen as of December 31, 2010.  Accrued benefits were based on years of service and average final compensation.  We do not provide any post-retirement benefits outside of the U.S. except as may be required by certain foreign jurisdictions.  Depending on the investment performance of our plan assets and other contributing factors, funding in a given year may not be required.

Our net periodic pension expense (income) related to our defined benefit plans was $0.1 million and less than $(0.1) million for the six months ended June 27, 2014 and June 28, 2013, respectively.
