Weighted average assumptions used to determine net periodic benefit cost for U.S. pension and other postretirement benefit plans were as follows (assumptions for non-U.S plans did not differ materially):

However, the discount rates for a limited number of plans were updated during 2011 and 2010 to reflect the remeasurement of these plans due to new union labor agreements, settlements, and (or) curtailments. The updated discount rates used were not significantly different from the discount rates presented.
