Retirement Benefit Plans

Effective at the beginning of fiscal 2018, the Company retrospectively adopted ASU No. 2017-07. See Recently Adopted Accounting Pronouncements in Note 1 for further discussion. As a result, only the service cost component of net periodic benefit cost is included in operating income. All other components are included in other expense, net in the accompanying condensed consolidated statement of income. The components of net periodic benefit cost are as follows:



	Three Months Ended March 31, 2018									Three Months Ended April 1, 2017
(In thousands, except percentages)	U.S. Pension			Non-U.S. Pension			Other Post-Retirement			U.S. Pension			Non-U.S. Pension			Other Post-Retirement
Service Cost	$	175		$	36		$	53		$	196		$	32		$	35
Interest Cost	298			30			43			314			24			39
Expected Return on Plan Assets	(322		)	(11		)	(1		)	(335		)	(8		)	—
Recognized Net Actuarial Loss	135			16			34			113			9			13
Amortization of Prior Service Cost	—			2			22			13			1			21
	$	286		$	73		$	151		$	301		$	58		$	108

The weighted average assumptions used to determine net periodic benefit cost are as follows:

Discount Rate	3.51		%	3.80		%	3.65		%	4.03		%	3.39		%	4.13		%
Expected Long-Term Return on Plan Assets	4.50		%	7.43		%	7.43		%	5.00		%	7.72		%	7.72		%
Rate of Compensation Increase	3.00		%	3.69		%	3.07		%	3.00		%	3.40		%	3.08		%

The Company does not plan to make any material cash contributions to its pension and post-retirement benefit plans other than to fund current benefit payments in 2018.
