With respect to the U.S. plans, the weighted average rate of compensation increase as of December 31, 2016 reflects only the Eco Services Hourly Pension Plan assumption of 3.00%, as both the Eco Services Pension Equity Plan and the PQ Corporation Retirement Plan were frozen to new accruals as of December 31, 2016 (and were included in the average at zero).
