Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments, Policy [Policy Text Block]

“Level 1” measurements use as inputs unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. These include commodity futures contracts that are traded on an exchange. These also include common stock warrants (Note 10) which are traded on the New York Stock Exchange.

“Level 2” measurements use as inputs market observable and corroborated prices for similar commodity derivative contracts. Assets and liabilities classified as Level 2 include over-the-counter (“OTC”) traded forward contracts and swaps.

“Level 3” measurements use as inputs information from a pricing service and internal valuation models incorporating observable and unobservable market data. These may include commodity derivatives, such as forwards and swaps for which there is not a highly liquid market, and therefore are not included in Level 2.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the measurement requires judgment and may affect the valuation of assets and liabilities and their placement within the fair value levels. At September 30, 2013, all of our physical fixed price forward purchases and sales contracts were being accounted for as normal purchases and normal sales.
