Fair Value Disclosures [Abstract] |
12. 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 2011 through 2013 and its conversion features associated with its convertible notes at fair value and designated them as Level 3 on their issuance date. 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, due to no anti-dilution protection features, were valued using the Black-Scholes Valuation Model. Significant assumptions used and related fair values for the warrants as of December 31, 2013 were as follows:

Convertible Notes – The conversion feature imbedded in the convertible notes was valued using a Monte Carlo Binomial Lattice-Based valuation methodology, adjusted for marketability restrictions. The Company estimated the fair value of the conversion feature until the retirement of the convertible notes in December 2013. 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. The following table summarizes fair value measurements by level at December 31, 2013 (in thousands):
