11	Retirement Plans

The Company sponsors various retirement plans. The Company adopted new accounting guidance which requires that an employer disaggregate the service cost component from other components of net benefit cost. As a result of the adoption of this standard, the components of net periodic benefit cost other than the service cost component are included in other income in the consolidated statements of operations and all previous periods have been adjusted accordingly. The summary of the components of net periodic pension costs for the plans for the three months ended March 31, 2018 and April 1, 2017 is as follows (in thousands):
