As disclosed in our 2016 Annual Report on Form 10-K, the Company has frozen its participation and benefit accruals for the pension plan and its contributions for individual benefit payments in the postretirement benefit plan.
During the third quarter of 2017, the Company revised its pension plan to offer certain participants a temporary opportunity to make an election to receive an immediate distribution from the pension plan. The window for this opportunity is between August 1, 2017 and November 24, 2017.
