Fair Value Measurements [Abstract]

Fair Value Measurements

Note 2 – Fair Value Measurements

The FASB authoritative guidance regarding fair value measurements establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted prices in active markets for assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The following table sets forth, by level within the fair value hierarchy, the Company’s financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of December 31, 2011 and September 30, 2011. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Derivative Financial Instruments

At December 31, 2011 and September 30, 2011, the derivative financial instruments reported in Level 1 consist of natural gas NYMEX futures contracts used in the Company’s Energy Marketing segment. Hedging collateral deposits of $4.5 million (at December 31, 2011) and $5.5 million (at September 30, 2011), which are associated with these futures contracts have been reported in Level 1 as well. The derivative financial instruments reported in Level 2 at December 31, 2011 and September 30, 2011 consist of natural gas price swap agreements used in the Company’s Exploration and Production and Energy Marketing segments. The fair value of the Level 2 price swap agreements is based on an internal, discounted cash flow model that uses observable inputs (i.e. LIBOR based discount rates and basis differential information, if applicable, at active natural gas and crude oil trading markets). The derivative financial instruments reported in Level 3 consist of all of the Company’s Exploration and Production segment’s crude oil price swap agreements at December 31, 2011 and September 30, 2011.Hedging collateral deposits of $20.6 million and $14.2 million associated with these crude oil price swap agreements have been reported in Level 1 at December 31, 2011 and September 30, 2011, respectively. The fair value of the Level 3 crude oil price swap agreements is based on an internal, discounted cash flow model that uses both observable (i.e. LIBOR based discount rates) and unobservable inputs (i.e. basis differential information of crude oil trading markets with low trading volume). Based on an assessment of the counterparties’ credit risk, the fair market value of the price swap agreements reported as Level 2 assets has been reduced by $2.2 million at December 31, 2011 and the fair market value of the price swap agreements reported as Level 2 and Level 3 assets has been reduced by $2.0 million at September 30, 2011. Based on an assessment of the Company’s credit risk, the fair market value of the price swap agreements reported as Level 2 and Level 3 liabilities at December 31, 2011 has been reduced by $0.1 million and the fair market value of the price swap agreements reported as Level 3 liabilities has not been reduced at September 30, 2011. These credit reserves were determined by applying default probabilities to the anticipated cash flows that the Company is either expecting from its counterparties or expecting to pay to its counterparties.

The tables listed below provide reconciliations of the beginning and ending net balances for assets and liabilities measured at fair value and classified as Level 3 for the quarters ended December 31, 2011 and 2010, respectively.For the quarters ended December 31, 2011 and December 31, 2010, no transfers in or out of Level 1 or Level 2 occurred. There were no purchases or sales of derivative financial instruments during the periods presented in the tables below.All settlements of the derivative financial instruments are reflected in the Gains/Losses Realized and Included in Earnings column of the tables below.
