Fair Value Disclosures [Abstract]

8. FAIR VALUE MEASUREMENTS.

The fair value hierarchy prioritizes the inputs used in valuation techniques into three levels as follows:

· Level 1 – Observable inputs – unadjusted quoted prices in active markets for identical assets and liabilities;

· Level 2 – Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration with market data; and

· Level 3 – Unobservable inputs – includes amounts derived from valuation models where one or more significant inputs are unobservable. For fair value measurements using significant unobservable inputs, a description of the inputs and the information used to develop the inputs is required along with a reconciliation of Level 3 values from the prior reporting period.

The Company recorded its warrants issued from 2010 through 2013 at fair value and designated them as Level 3 on their issuance dates.

Warrants – Except for the warrants issued September 26, 2012, the warrants were valued using a Monte Carlo Binomial Lattice-Based valuation methodology, adjusted for marketability restrictions. The warrants issued September 26, 2012, did not contain any anti-dilution protection features. As a result, the warrants were valued using the Black-Scholes Valuation Model. Of the various inputs used, the volatility and the current price of the Company’s common stock most significantly impact the fair value adjustments of the warrants. As the Company’s common stock increases or decreases, the valuation of the warrants will increase or decrease, respectively. As the estimated volatility of the Company’s common stock increases or decreases, the valuation of the warrants will increase or decrease, respectively. These changes may result in significantly higher or lower fair value measurements from period to period.

Significant assumptions used and related fair values for the warrants as of June 30, 2013 were as follows:

Original Issuance	Exercise Price		Volatility			Risk-Free Interest Rate			Term (years)		Discount for marketability restrictions			Warrants Outstanding		Fair Value

Significant assumptions used and related fair values for the warrants as of December 31, 2012 were as follows:

Original Issuance	Exercise Price		Volatility			Risk-Free Interest Rate			Term (years)		Discount for marketability restrictions			Warrants Outstanding		Fair Value
09/26/2012	$	8.85		70.2	%		0.36	%		2.74		53.9	%		1,833,000	$	1,112,000

																$	4,892,000

Convertible Notes – The conversion feature imbedded in the convertible notes was valued using a combination of a Monte Carlo Binomial Lattice-Based valuation methodology, adjusted for marketability restrictions. Significant assumptions used and related fair value for the conversion feature as of June 30, 2013 were as follows:

Instrument	Initial Conversion Price		Volatility			Risk-Free Interest Rate			Term (years)		Discount for marketability restrictions			Fair Value
Series A and B Notes	$	15.00		49.1	%		0.15	%		0.8		16.8	%	$	3,710,000

Other Derivative Instruments – The Company’s other derivative instruments consist of commodity positions. The fair value of the commodity positions are based on quoted prices on the commodity exchanges and are designated as Level 1.
