During the three months ended March 31, 2018, we did not make any contributions to our worldwide pension plans. Effective January 1, 2010, the U.S. plan was amended to exclude new hires and rehires from participating in the plan. In addition, we eliminated benefit accruals under the U.S. plan as of January 1, 2011, thus “freezing” the defined benefit pension plan. Under the plan freeze, no pay credits were made to a participant’s account balance after December 31, 2010. However, interest credits will continue in accordance with the annual update process. We presently anticipate contributing approximately $3.2 million to fund our worldwide pension plans in the next twelve months.
