In the first quarter of 2014, we made a one-time cash payment to a former employee of $0.8 million in accordance with the provisions of his retirement contract related to his participation in the Pension Restoration Plan. This payment resulted in a settlement charge of approximately $0.1 million, which was recognized in the first quarter of 2014.

In the second quarter of 2013, we made changes to our retirement plans in order to better plan and manage related expenses which have a significant and variable impact on earnings. Effective June 30, 2013, for salaried and non-union hourly employees in the U.S. and effective December 31, 2013 for union employees in the U.S., benefits under our defined benefit pension plans will no longer accrue. These decisions resulted in a curtailment charge of $1.5 million that was recognized in the second quarter of 2013 in "Restructuring and impairment charges" in our condensed consolidated statements of income (loss).
