The Company has established policies and procedures to manage such risks. The Company has a Risk Management Committee comprised of Company officers and management to oversee the risk management program as defined in its risk management policy. The purpose of the risk management program is to minimize adverse impacts on earnings resulting from volatility of energy prices, counterparty credit risks, and other risks related to the energy commodity business. In order to mitigate the risk of natural gas market price volatility related to firm commitments to purchase or sell natural gas, from time to time the Company and its subsidiaries have entered into fixed contracts. Such arrangements may be used to protect profit margins on future obligations to deliver gas at a fixed price, or to protect against adverse effects of potential market price declines on future obligations to purchase gas at fixed prices. The Company accounts for these contracts in accordance with ASC 815, Derivatives and Hedging. In accordance with ASC 815, such contracts are reflected in the balance sheet as assets or liabilities and valued at “fair value,” determined as of the balance sheet date. Fair value accounting treatment is also referred to as “mark-to-market” accounting. Mark-to-market accounting results in disparities between reported earnings and realized cash flow. The changes in the derivative values are reported in the income statement as an increase or (decrease) in revenues without regard to whether any cash payments have been made between the parties to the contract. ASC 815 specifies that contracts for purchase or sale at fixed prices and volumes must be valued at fair value (under mark-to-market accounting) unless the contracts qualify for treatment as a “normal purchase or normal sale.”   At June 30, 2013 and December 31, 2012, all of the Company’s fixed contracts for purchase or sale at fixed prices and volumes qualified for treatment as a “normal purchase or normal sale.” falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for derivative instruments and hedging activities including, but not limited to, risk management strategies, non-hedging
