6. Derivatives

During the three months ended March 31, 2013, we have adopted the provisions of ASU 2011-11 Balance Sheet (Topic 210): Disclosures About Offsetting Assets and Liabilities and ASU 2013-01 Balance Sheet (Topic 210): Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities, which require the supplemental disclosure of any derivative amounts presented on a net basis on our consolidated balance sheets. We currently present our unrealized gains (losses) on commodity derivatives on a gross basis on our consolidated balance sheets, and thus no material impact was noted.

At March 31, 2013, we had the following commodity derivatives positions outstanding:


Commodity and Period	Contract Type	Volume Transacted	Contract Price
Crude Oil
2013	Collar	650 Bbls/d	$90.00/Bbl – $105.80/Bbl
2013	Collar	450 Bbls/d	$90.00/Bbl – $101.45/Bbl
2013 (1)	Collar	1,200 Bbls/d	$90.35/Bbl – $100.35/Bbl
2014	Collar	550 Bbls/d	$90.00/Bbl – $105.50/Bbl

Crude Oil Basis Differential (Midland/Cushing)
2013 (2)	Swap	2,300 Bbls/d	$1.10/Bbl

Natural Gas
2013	Swap	200,000 MMBtu/month	$3.54/MMBtu
2013	Swap	190,000 MMBtu/month	$3.80/MMBtu
2014	Swap	360,000 MMBtu/month	$4.18/MMBtu

(1)	February 2013 – December 2013

(2)	March 2013 – December 2013

Subsequent to March 31, 2013, we entered into a natural gas collar covering 100,000 MMBtu per month for May 2013 through December 2013 at a floor of $4.00/MMBtu and a ceiling of $4.36/MMBtu. We also entered into an oil collar covering 950 Bbls per day for 2014 at a floor of $85.05/Bbl and a ceiling of $95.05/Bbl.

The following table summarizes the fair value of our open commodity derivatives as of March 31, 2013, and December 31, 2012 (in thousands).


	Asset/Liability Derivatives
	Balance Sheet Location	Fair Value
		March 31,			December 31,
		2013			2012
Derivatives not designated as hedging instruments
Commodity derivatives	Unrealized (loss) gain on commodity derivatives	$	(1,666	)	$	2,433

The following table summarizes the change in the fair value of our commodity derivatives (in thousands).


	Income Statement Location	Three Months Ended
		March 31,
		2013		2012
Derivatives not designated as hedging instruments
Commodity derivatives	Unrealized loss on commodity derivatives	$	(4,100)	$	(2,672)
	Realized gain (loss) on commodity derivatives		307		(484)

		$	(3,793)	$	(3,156)

Unrealized gains and losses, at fair value, are included on our consolidated balance sheets as current or non-current assets or liabilities based on the anticipated timing of cash settlements under the related contracts. Changes in the fair value of our commodity derivative contracts are recorded in earnings as they occur and included in other income (expense) on our consolidated statements of operations. We estimate the fair values of swap contracts based on the present value of the difference in exchange-quoted forward price curves and contractual settlement prices multiplied by notional quantities. We internally valued the option contracts using industry-standard option pricing models and observable market inputs. We use our internal valuations to determine the fair values of the contracts that are reflected on our consolidated balance sheets. Realized gains and losses are also included in other income (expense) on our consolidated statements of operations.

We are exposed to credit losses in the event of nonperformance by the counterparties on our commodity derivatives positions and have considered the exposure in our internal valuations. However, we do not anticipate nonperformance by the counterparties over the term of the commodity derivatives positions.

To estimate the fair value of our commodity derivatives positions, we use market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the market approach for recurring fair value measurements and attempt to use the best available information. We determine the fair value based upon the hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and lowest priority to unobservable inputs (Level 3 measurement). The three levels of fair value hierarchy are as follows:

•

Level 1 – Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. At March 31, 2013, we had no Level 1 measurements.

•

Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Our derivatives, which consist primarily of commodity swaps and collars, are valued using commodity market data which is derived by combining raw inputs and quantitative models and processes to generate forward curves. Where observable inputs are available, directly or indirectly, for substantially the full term of the asset or liability, the instrument is categorized in Level 2. At March 31, 2013, all of our commodity derivatives were valued using Level 2 measurements.

•

Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. At March 31, 2013, our Level 3 measurements were limited to our asset retirement obligation.
