As of June 30, 2013 and 2012, the fair values of the Company’s Level 1 financial instruments were $192,620 and $141,107, respectively. These financial instruments consist of cash equivalents, including money market accounts. As of June 30, 2013 and 2012, the Company held no Level 2 financial instruments.
 
 
As of June 30, 2013 and 2012, the fair values of the Company’s Level 3 financial instruments totaled $650,638 and $918,566, respectively. The Level 3 financial instruments consist of common stock warrants issued by the Company in March 2011 and March 2007, which include features requiring liability treatment of the warrants. The fair value of warrants issued in March 2011 (see Notes 12 and 13) to purchase 3.9 million shares of the Company’s common stock is based on valuations performed by an independent third party valuation firm. The fair value was determined using proprietary valuation models using the quality of the underlying securities of the warrants, restrictions on the warrants and security underlying the warrants, time restrictions and precedent sale transactions completed in the secondary market or in other private transactions. The fair value of warrants issued in March 2007 to purchase 903,955 shares of the Company’s common stock was estimated by the Company to be $0 using the Black-Scholes with the following assumptions: dividend yield of 0%, expected stock price volatility of 46.6, risk free interest rate of 0.04, and an expected life of 0.2 years. There were no transfers of assets or liabilities between level 1, level 2, or level 3 during the years ended June 30, 2013 and 2012.
