Schedule of Assumptions Used

Weighted-average assumptions used in accounting for the U.S. defined benefit pension plans and postretirement benefit plans are as follows:

	Pension Benefit						Postretirement Benefit
	2013		2012		2011		2013		2012		2011
Discount rate for obligations	5.01	%	4.24	%	4.78	%	4.48	%	3.69	%	4.54	%
Discount rate for benefit costs	4.24	%	4.78	%	5.50	%	3.69	%	4.54	%	4.66	%
Rate of increase in compensation levels	N/A		N/A		N/A		N/A		N/A		N/A
Expected long-term rate of return on plan assets	7.50	%	7.75	%	7.75	%	N/A		N/A		N/A

The Company utilizes a high-quality (Aa) corporate bond yield curve as the basis for its domestic discount rate for its pension and postretirement benefit plans. Management believes this yield curve removes the impact of including additional required corporate bond yields (potentially considered in the above-median curve) resulting from the uncertain economic climate that does not necessarily reflect the general trend in high-quality interest rates.

Actuarial valuations of the Company's non-U.S. defined benefit pension plans were prepared as of December 31, 2013, 2012 and 2011. Weighted-average assumptions used in accounting for the non-U.S. defined benefit pension plans are as follows:

	Pension Benefit
	2013		2012		2011
Discount rate for obligations	4.50	%	4.50	%	4.80	%
Discount rate for benefit costs	4.50	%	4.80	%	5.50	%
Rate of increase in compensation levels	4.10	%	3.70	%	4.00	%
Expected long-term rate of return on plan assets	5.40	%	5.50	%	7.00	%
