During the three month period ended June 30, 2015, the Company approved and announced its plan to freeze the defined benefit pension plan in the Netherlands effective September 30, 2016, which resulted in the recognition of a $1 million curtailment gain. This gain was offset by the recognition of a $1 million curtailment loss for a defined benefit pension plan in Germany, which was the result of a restructuring initiative.
