Derivatives and Risk Management

(5)  DERIVATIVES AND RISK MANAGEMENT

The Company is exposed to volatility in market prices and basis differentials for natural gas and crude oil which impacts the predictability of its cash flows related to the sale of natural gas and oil. These risks are managed by the Company's use of certain derivative financial instruments. At December 31, 2011 and 2010, the Company's derivative financial instruments consisted of price swaps, costless-collars and basis swaps. A description of the Company's derivative financial instruments is provided below:

Fixed price swaps               The Company receives a fixed price for the contract and pays a floating market price to the counterparty.

Floating price swaps          The Company receives a floating market price from the counterparty and pays a fixed price.

Costless-collars                   Arrangements that contain a fixed floor price (put) and a fixed ceiling price (call). If the market price exceeds the call strike price or falls below the put strike price, the Company receives the fixed price and pays the market price. If the market price is between the call and the put strike price, no payments are due from either party.

Basis swaps                          Arrangements that guarantee a price differential for natural gas from a specified delivery point. The Company receives a payment from the counterparty if the price differential is greater than the stated terms of the contract and pays the counterparty if the price differential is less than the stated terms of the contract.  

GAAP requires that all derivatives be recognized in the balance sheet as either an asset or liability and be measured at fair value. Under GAAP, certain criteria must be satisfied in order for derivative financial instruments to be classified and accounted for as either a cash flow or a fair value hedge. Accounting for qualifying hedges requires a derivative's gains and losses to be recorded either in earnings or as a component of other comprehensive income. Gains and losses on derivatives that are not elected for hedge accounting treatment or that do not meet hedge accounting requirements are recorded in earnings.

The Company utilizes counterparties for its derivative instruments that it believes are credit-worthy at the time the transactions are entered into and the Company closely monitors the credit ratings of these counterparties. Additionally, the Company performs both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. However, the events in the financial markets in recent years demonstrate there can be no assurance that a counterparty will be able to meet its obligations to the Company.

The balance sheet classification of the derivative financial instruments are summarized below at December 31, 2011 and 2010:

Cash Flow Hedges

The reporting of gains and losses on cash flow derivative hedging instruments depends on whether the gains or losses are effective at offsetting changes in the cash flows of the hedged item. The effective portion of the gains and losses on the derivative hedging instruments are recorded in other comprehensive income until recognized in earnings during the period that the hedged transaction takes place. The ineffective portion of the gains and losses from the derivative hedging instrument recognized in earnings immediately.

As of December 31, 2011, the Company had cash flow hedges on the following volumes of natural gas production and gas-in-underground storage (in Bcf):

Year:	Fixed price swaps	Costless-collars
2012	185.9	80.5
2013	185.2	0

As of December 31, 2011, the Company recorded a gain in accumulated other comprehensive income related to its hedging activities of $424.9 million net of a deferred income tax liability of $276.2 million. The amount recorded in accumulated other comprehensive income will be relieved over time and recognized in the statement of operations as the physical transactions being hedged occur. Assuming the market prices of natural gas futures as of December 31, 2011 remain unchanged, the Company would expect to transfer an aggregate after-tax net gain of approximately $303.2 million from accumulated other comprehensive income to earnings during the next 12 months. Gains or losses from derivative instruments designated as cash flow hedges are reflected as adjustments to natural gas sales in the consolidated statements of operations. Natural gas sales included a realized gain from settled contracts of $320.1 million for the year ended December 31, 2011 compared to a realized gain of $301.5 million for the year ended December 31, 2010. Volatility in  net income, comprehensive income and accumulated other comprehensive income may occur in the future as a result of the Company's derivative activities.

The following tables summarize the before tax effect of all cash flow hedges on the consolidated financial statements for the years ended December 31, 2011 and 2010.

Fair Value Hedges

For fair value hedges, the gain or loss on the derivative instrument as well as the offsetting gain or loss on the hedged item are recognized in earnings immediately. As of December 31, 2011 and December 31, 2010, the Company had no material fair value hedges.

 Other Derivative Contracts

Although the Company's basis swaps meet the objective of managing commodity price exposure, these trades are typically not entered into concurrent with the Company's derivative instruments that qualify as cash flow hedges and therefore do not generally qualify for hedge accounting. Basis swap derivative instruments that do not qualify as cash flow hedges are recorded on the balance sheet at their fair values under hedging assets, other assets and hedging liabilities, as applicable, and all realized and unrealized gains and losses related to these contracts are recognized immediately in the consolidated statements of operations as a component of natural gas sales.

As of December 31, 2011, the Company had basis swaps on natural gas production that did not qualify for hedge accounting treatment of 36.6 Bcf, 30.1 Bcf and 9.1 Bcf for 2012, 2013, and 2014, respectively.

The following tables summarize the before tax effect of basis swaps that did not qualify for hedge accounting on the uncondensed consolidated statements of operations for the years ended December 31, 2011 and 2010.
