Multiemployer and Defined Benefit Pension Plans
MOPP. During the three months ended March 31, 2018, the Company received notification from the AMOPP that the Company’s withdrawal liability as of September 30, 2017 would have been $34.4 million based on an actuarial valuation performed as of that date. That liability may change in future years based on various factors, primarily employee census. As of March 31, 2018, the Company has no intention to withdraw from the AMOPP and no deficit amounts have been invoiced. Depending upon the results of the future actuarial valuations and the ten-year rehabilitation plan, it is possible that the AMOPP will experience further funding deficits, requiring the Company to recognize additional payroll related operating expenses in the periods invoices are received or contribution levels are increased.
