Schedule of Assumptions Used

The weighted average actuarial assumptions utilized to calculate the net periodic benefit costs for the U.S. and significant non-U.S. defined benefit plans are as follows:

Combined U.S. and significant non-U.S. plans	Pension Benefits				Post-retirement Benefits
June 30,	2017		2016		2017		2016
Weighted average assumptions:
Expected return on plan assets	6.64	%	7.07	%	—		—
Discount rate	3.40	%	4.11	%	3.64	%	4.12	%
Rate of compensation increase*	1.77	%	2.44	%	—		—

*The 2017 assumption does not include a rate of compensation increase for the U.S. defined benefit plans since future benefit accruals were discontinued for those plans after December 31, 2016.
