New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Accounting Changes and Error Corrections [Text Block]	Recent Accounting Pronouncements Fair Value Accounting: In May 2011, the FASB issued ASU 2011-04, which amended Fair Value Measurements and Disclosures - Overall (ASC Topic 820-10) to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are consistent between U.S. GAAP and International Financial Reporting Standards. This update changed certain fair value measurement principles and enhanced the disclosure requirements, particularly for level 3 fair value measurements. We adopted this update prospectively effective for our fiscal year beginning January 1, 2012. This update did not have a material effect on our financial condition, results of operations or disclosures. Balance Sheet Offsetting: In December 2011, the FASB issued ASU 2011-11, Balance Sheet (Topic 210), Disclosures about Offsetting Assets and Liabilities. ASU 2011-11 requires entities to disclose both gross information and net information about both instruments and transactions eligible for offset in the Balance Sheet and instruments and transactions subject to an agreement similar to a master netting arrangement to enable users of their financial statements to understand the effects of offsetting and related arrangements on their financial position. This update is effective for our fiscal year beginning January 1, 2013 and must be applied retrospectively. The principal impact from this update will be to expand disclosures regarding our financial instruments. We currently report our derivative assets and liabilities on a gross basis in the Balance Sheet even in those instances where offsetting may be allowed under a master netting agreement.

The entire disclosure for reporting accounting changes and error corrections. It includes the conveyance of information necessary for a user of the Company's financial information to understand all aspects and required disclosure information concerning all changes and error corrections reported in the Company's financial statements for the period.
