The Company remeasures its U.S. pension plan when year-to-date aggregate lump sum settlements exceed anticipated interest costs for the year, and in each subsequent quarter of that fiscal year. Because aggregate lump sum settlements did not exceed anticipated 2017 annual interest costs during the first quarter of 2017, there was no remeasurement, and therefore no actuarial gain or loss was recognized during the three months ended March 31, 2017. Because aggregate lump sum settlements exceeded anticipated 2016 annual interest costs during the first quarter of 2016, the Company remeasured its U.S. pension plan during the first quarter of 2016 and recognized a net actuarial loss of $6.1 million during the three months ended March 31, 2016.

During the three months ended March 31, 2017, the Company contributed $0.1 million to foreign pension plans. During the three months ended March 31, 2016, the Company made no contributions to pension plans.
