Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES We recorded tax (provisions) benefits of $2.4 million and $2.9 million for the three months ended September 30, 2011 and 2010, respectively, and $(0.5) million and $6.4 million for the nine months ended September 30, 2011 and 2010, respectively, due to changes in the valuation allowance on deferred tax assets. The valuation allowance was adjusted due to increases or decreases in offsetting deferred tax liabilities, primarily as a result of unrealized gains or losses on derivative instruments that qualify for hedge accounting. In determining the carrying value of a deferred tax asset, accounting standards provide for the weighing of evidence in estimating whether and how much of a deferred tax asset may be recoverable. As the Company has incurred net operating losses in prior years, relevant accounting guidance suggests that cumulative losses in recent years constitute significant negative evidence, and that future expectations about income are insufficient to overcome a history of such losses. In 2008, the Company reduced the carrying value of its net deferred tax asset to zero and maintained that position as of September 30, 2011 and December 31, 2010. The valuation allowance has no impact on our net operating loss (“NOL”) position for tax purposes, and if the Company generates taxable income in future periods, the Company will be able to use its NOLs to offset taxes due at that time. The Company will continue to assess the valuation allowance against deferred tax assets considering all available evidence obtained in future reporting periods.
