Description of New Accounting Pronouncements Not yet Adopted [Text Block]	11. Accounting Pronouncements On June 16, 2011 the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2011-05: Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This ASU will change the way we present comprehensive income. We currently present comprehensive income in the notes to our condensed consolidated financial statements during interim periods (see Note 6, Other Comprehensive Income, above) and as a component of the statement of changes in shareholder’s equity in our annual financial statements. This update eliminates the option of presenting other comprehensive income in the statement of changes in shareholder’s equity and requires that an entity present the components of net income and comprehensive income in either in a single continuous statement of comprehensive income or in two separate but consecutive financial statements. The provisions of ASU 2011-05 are to be applied retrospectively and are effective for fiscal years beginning after December 15, 2011, including both interim and annual periods thereafter. ASU 2011-05 is effective for us beginning with our fiscal 2013 first quarter ending April 29, 2012. This ASU will only affect our financial statement presentation; consequently, there will be no impact to our consolidated balances sheets or consolidated statements of operations other than the way in which we present comprehensive income. We are currently evaluating the presentation options allowed under this update.
