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.

 

Warrants – The Company’s warrants were valued using a Monte Carlo Binomial Lattice-Based valuation methodology, adjusted for marketability restrictions. The Company recorded its warrants issued in 2012 at fair value and designated them as Level 3 on their issuance dates.

 

Significant assumptions used and related fair values for the warrants as of March 31, 2017 were as follows:

 

Original
Issuance
Exercise
Price
Volatility Risk Free
Interest
Rate
Term
(years)
Market
Discount
Warrants
Outstanding
Fair Value
07/3/2012 $6.09 38.2% 0.76% 0.26 7.6% 211,000 $196,000

 

Significant assumptions used and related fair values for the warrants as of December 31, 2016 were as follows:

 

Original
Issuance
Exercise
Price
Volatility Risk Free
Interest

07/3/2012 $6.09 40.9% 0.62% 0.50 11.3% 211,000 $651,000

 

The estimated fair values of the warrants are affected by the above underlying inputs. Observable inputs include the values of exercise price, stock price, term and risk-free interest rate. As separate inputs, an increase (decrease) in either the term or risk free interest rate will result in an increase (decrease) in the estimated fair value of the warrants.

 

Unobservable inputs include volatility and market discount. An increase (decrease) in volatility will result in an increase (decrease) in the estimated fair value of the warrants and an increase (decrease) in the market discount will result in a decrease (increase) in the estimated fair value of the warrants.

 

The volatility utilized was a blended average of the Company’s historical volatility and implied volatilities derived from a selected peer group. The implied volatility component has remained relatively constant over time given that implied volatility is a forward-looking assumption based on observable trades in public option markets. Should the Company’s historical volatility increase (decrease) on a go-forward basis, the resulting fair value of the warrants would increase (decrease).

 

The market discount, or a discount for lack of marketability, is quantified using a Black-Scholes option pricing model, with a primary model input of assumed holding period restriction. As the assumed holding period increases (decreases), the market discount increases (decreases), conversely impacting the fair value of the warrants.

 

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