CY2018Q1	cwco	Subscription Agreement Description SubscriptionAgreementDescription	The Agreement calls for NSC to retain a minimum of 25% of the equity in AdR. One or more affiliates of Greenfield SPV VII, S.A.P.I. de C.V. (“Greenfield”), a Mexico company managed by an affiliate of a leading U.S. asset manager, would acquire a minimum of 55% of the equity of AdR. The Agreement also provided Suez MA with the option to purchase 20% of the equity of AdR. If Suez MA did not exercise this option, NSC would retain 35% of the equity of AdR and Greenfield will acquire 65% of the equity of AdR. The Agreement became effective when the certain conditions precedent related to the Project were met. The aggregate investment to be made by the equity partners in the Project, in the form of equity and subordinated shareholder loans, is presently estimated at approximately 20% of the total cost of Phase 1 of the Project.
