Employee Benefit Plan [Abstract]

Schedule of Accumulated and Projected Benefit Obligations

The following tables provide a rollforward of the projected benefit obligation and the fair value of plan assets, set forth the defined benefit retirement plans’ funded status and provide detail of the components of net periodic pension cost calculated for the U.K. and Norway pension plans. The measurement date adopted is March 31. For the purposes of amortizing gains and losses, the 10% corridor approach has been adopted and assets are taken at fair market value. Any such gains or losses are amortized over the average remaining life expectancy of the plan members.
