13)	Pension Plans

As a result of the Newport Merger, the Company has assumed all assets and liabilities of Newport’s defined benefit pension plans, which cover substantially all of its full-time employees in France, Germany, Israel and Japan. In addition, there are certain pension liabilities relating to former employees in the United Kingdom. The German plan is unfunded, as permitted under the plan and applicable laws.

For financial reporting purposes, the calculation of net periodic pension costs was based upon a number of actuarial assumptions including a discount rate for plan obligations, an assumed rate of return on pension plan assets and an assumed rate of compensation increase for employees covered by the plan. All of these assumptions were based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions would impact future expense recognition and the cash funding requirements of the Company’s pension plans.

The Company has included the net periodic benefit costs for the plans from the date of the acquisition on April 29, 2016 through September 30, 2016. The net periodic benefit costs included the following components:


	Three months ended September 30, 2016			Nine months ended September 30, 2016
Service cost	$	596		$	1,000
Interest cost on projected benefit obligation		121			201
Expected return on plan assets		(44	)		(75	)

	$	673		$	1,126
