AMOPP. During the nine months ended September 30, 2016, the Company received notification from the AMOPP that the Company’s withdrawal liability as of September 30, 2015 was $46.7 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 September 30, 2016, 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.
