RE:In Three Months... According to this, the standstill is already over in 2 months not 3:
"The Transaction effective date is April 1, 2017 and the closing of the Transaction is expected to occur on or before July 31, 2017."
"Upon closing of the Transaction, subject to certain conditions set out in an investor rights and governance agreement (the "Investor Rights and Governance Agreement"), Glencore will have certain board nomination rights (described below), the right to participate in any future equity offerings by the Company in order to maintain its pro rata ownership in Trevali and consent rights on any future material asset sales. Pursuant to the Investor Rights and Governance Agreement, Glencore has agreed to a 36 month standstill (the "Standstill") and to hold the Share Consideration for a period of at least 24 months following the closing of the Transaction. The Standstill prohibits Glencore from taking certain specified actions without Trevali’s approval, including, among other things, launching a takeover bid or increasing its ownership in Trevali."
