|Derivative Instruments and Hedging Activities Disclosure [Abstract]
The Company issued warrants in 2013 for the purchase of 301,778 shares of common stock, which had provisions that included anti-dilution protection, cashless exercise provisions and, under certain conditions, granted holders the right to request the Company repurchase the warrant. Accordingly, these warrants were considered derivative instruments and as of December 31, 2013, the fair values of $19,932 were recorded respectively as a derivative warrant liability. On June 30, 2014, these warrant agreements were modified to eliminate the anti-dilution protection and accordingly these warrants were no longer considered a derivative liability and the fair value of $48,380 shares was reclassified and charged as an addition to Additional-Paid in Capital.
To value the derivative warrant liability, the Company used the Black-Scholes option pricing model and assumptions that considered, among other factors, the fair value of the underlying stock, risk-free interest rate, volatility, expected life and dividend rates in estimating fair value for the warrants considered to be derivative instruments. The increase in the fair value of the derivative warrant liability at June 30, 2014 from December 31, 2013 was $28,448 and was recognized in the Consolidated Statement of Operations as a change in the fair value of a warrant liability.
