(1) Due to the approval of a plan to close a U.S. facility, pension assumptions were reevaluated on June 7, 2011 for the remeasurement of a U.S. Wage Plan covering certain union employees. See Note 3, “Business Segment Information”. The facility closure resulted in a curtailment loss of $1.4 million and a contractual termination benefit charge of $4 million.
