Derivative Instruments

5.Derivative Instruments

We utilize derivative instruments to mitigate our financial exposure to natural gas and crude oil price volatility as well as interest rates attributable to our debt instruments. We are not engaged in the trading of derivative instruments for speculative purposes. The derivative instruments, which are placed with financial institutions that we believe are acceptable credit risks, generally take the form of costless collars and swaps. Our derivative instruments are not formally designated as hedges.

Commodity Derivatives

We determine the fair values of our oil and gas derivative instruments using third-party quoted forward prices for NYMEX Henry Hub natural gas and West Texas Intermediate crude oil as of the end of the reporting period and discount rates adjusted for the credit risk of our counterparties if the derivative is in an asset position and our own credit risk if the derivative is in a liability position.

The following table sets forth our commodity derivative positions as of June 30, 2011:

Interest Rate Swaps

In December 2009, we entered into an interest rate swap agreement to establish variable rates on approximately one-third of the face amount of the outstanding obligation under the 10.375% Senior Notes due 2016 (“2016 Senior Notes”).

The following table sets forth the terms and positions of our interest rate swap assets as of the periods presented:

	Notional		Swap Interest Rates1				June 30,		December 31,
Term	Amount		Pay	Receive			2011		2010
Through June 2013	$	100,000	LIBOR + 8.175%		10.375	%	$	2,715	$	2,590

1 References to LIBOR represent the 3-month rate.

The effects of derivative gains (losses) and cash settlements of our commodity and interest rate derivatives are reported as adjustments to reconcile net income to net cash provided by operating activities from continuing operations. These items are recorded in the “Derivative contracts: Net gains” and “Derivative contracts: Cash settlements” captions on our Condensed Consolidated Statements of Cash Flows.

The following table summarizes the fair value of our derivative instruments, as well as the locations of these instruments, on our Condensed Consolidated Balance Sheets as of the periods presented:

As of June 30, 2011, we reported a commodity derivative asset of $14.3 million.  The contracts associated with this position are with four counterparties, all of which are investment grade financial institutions, and are substantially concentrated with two of those counterparties. This concentration may impact our overall credit risk, either positively or negatively, in that these counterparties may be similarly affected by changes in economic or other conditions.  We neither paid nor received collateral with respect to our derivative positions.  No significant uncertainties exist related to the collectability of amounts that may be owed to us by these counterparties.
