Investment, Additional Information | | | | The agreement had a deadline of June 30, 2015, for Apogee and Midtown Partners to obtain the requisite approvals from FINRA. Apogee did not file for approval on time, and consequently pursuant to the terms of the Agreement, there are several penalties that will apply, including the cancellation of 700,000 shares of IGC stock and a penalty of $125,000 owed by Apogee to us.  We are not seeking to consummate the acquisition of the remaining interest in Midtown Partners at this time. | |
