Common Stock Sales The Company may sell common stock on the open market from time to time. The proceeds of these sales may be used for general corporate purposes or to pay obligations related to the Company's outstanding Series 1 and Series B preferred shares. During the six months ended April 30, 2015, the Company sold 11,523,647 shares of the Company's common stock at prevailing market prices through periodic trades on the open market and raised approximately $16.7 million, net of fees. Outstanding Warrants On September 4, 2013, the Company entered into a co-marketing agreement with NRG for the marketing and sales of the Company's power plants. The terms of the agreement included the issuance of warrants to NRG that permit NRG to purchase up to 5.0 million shares of the Company's common stock at predetermined prices based on attaining minimum sales goals. The first tranche of 1.25 million warrants expired unvested on March 1, 2014 and the second tranche of 1.5 million warrants expired unvested on December 31, 2014. There is one tranche of 2.25 million warrants remaining with a strike price of $1.98 and a qualifying order vesting date through September 2015 and an expiration date of August 2018. Any costs associated with the warrants will be recorded as a reduction of potential future revenue recorded under the arrangement. No warrants were vested and no expense was recorded as of April 30, 2015. On July 30, 2014, the Company also issued a warrant to NRG in conjunction with entry into a Securities Purchase Agreement for the sale of common stock. Pursuant to the warrant agreement, NRG has the right to purchase up to 2.0 million shares of the Company's common stock at an exercise price of $3.35 per share. The warrant has a term of three years from the Closing Date. The warrants qualified for permanent equity accounting treatment.
