GPI has been funding Moxie Patriot LLC (“Moxie Patriot”) in the development of this power-plant project and has advanced approximately $3.7 million in working capital funding to the project as of April 30, 2013. The Company also disclosed that Moxie had entered into an agreement with a third party investor for the purchase of Moxie’s membership interest. The investor, who is the same investor as the one under contract to purchase Moxie Liberty, agreed to provide advances for certain preconstruction costs. The consummation of the purchase of Moxie Patriot is contingent upon the third party investor securing permanent financing for the project. Although a complete analysis has not been conducted, these events may form the basis for a determination in a future reporting period that Moxie Patriot should be deconsolidated.
