New Accounting Pronouncement or Change in Accounting Principle, Current Period Disclosures [Abstract]
New Accounting Pronouncements [Text Block]	New Accounting Standards Accounting Standards Issued In May 2011, the Financial Accounting Standards Board (FASB) issued accounting guidance related to fair value measurement, which amends current guidance to achieve common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards. The amendments generally represent clarification of how the concepts of highest and best use and valuation premise in a fair value measurement are relevant only when measuring the fair value of nonfinancial assets and are not relevant when measuring the fair value of financial assets or of liabilities. In addition, the guidance expanded the disclosures for the unobservable inputs for Level 3 fair value measurements, requiring quantitative information to be disclosed related to (1) the valuation processes used, (2) the sensitivity of the fair value measurement to changes in unobservable inputs and the interrelationships between those unobservable inputs, and (3) use of a nonfinancial asset in a way that differs from the asset’s highest and best use. This revised guidance is effective for interim and annual periods beginning after December 15, 2011 and early application is prohibited. We do not expect this pronouncement to have a material effect on our consolidated financial statements. In June 2011, the FASB issued an accounting pronouncement that provides new guidance on the presentation of comprehensive income in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. The provisions of this pronouncement are effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. This guidance concerns disclosure only and will not have a material effect on our consolidated financial statements. Accounting Standards Adopted There have been no new accounting pronouncements or changes in accounting pronouncements adopted during the nine months ended September 30, 2011 that are of significance, or potential significance, to us.
