New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Schedule Of New Accounting Pronouncements And Changes In Accounting Principles Text Block	In June 2009, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance that amends the consolidation guidance applicable to variable interest entities and requires additional disclosures concerning an enterprise's continuing involvement with variable interest entities. The guidance is effective for our fiscal year beginning October 1, 2010. We have adopted this guidance and it did not have a material impact on our consolidated financial statements. In May 2011, the FASB issued guidance to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between generally accepted accounting principles in the United States and International Financial Reporting Standards. The guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. The guidance is effective for our fiscal year beginning October 1, 2012. We do not believe that the adoption of this guidance will have a material impact on our consolidated financial statements. In June 2011, the FASB issued guidance on the presentation of comprehensive income in an entity's financial statements. The guidance requires that comprehensive income be presented either in one continuous statement or in two separate but consecutive statements presenting the components of net income and its total, the components of other comprehensive income and its total, and total comprehensive income. The guidance also requires that reclassification adjustments from other comprehensive income to net income be presented in both the components of net income and the components of other comprehensive income. The guidance is effective for our fiscal year beginning October 1, 2012. We do not believe that the adoption of this guidance will have a material impact on our consolidated financial statements.
