Description of New Accounting Pronouncements Not yet Adopted [Text Block]	12. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2011-05, "Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income" ("ASU 2011-05"), which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders’ equity. Instead we must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. In December 2011, the FASB issued ASU No. 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassification of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" ("ASU 2011-12"). ASU 2011-12 defers the requirement in ASU 2011-05 to present reclassification adjustments for each component of accumulated other comprehensive income ("AOCI") in both other comprehensive income and net income on the face of the financial statements and the presentation of reclassification adjustments is not required in interim periods. We expect to continue to present amounts reclassified out of AOCI on the face of the financial statements. The effective dates of ASU 2011-12 are consistent with the effective dates of ASU 2011-05, which was effective for us on July 1, 2012. Although adopting the guidance has not had an impact on our accounting for comprehensive income (loss), it does affect our presentation of components of comprehensive income (loss) by eliminating the historical practice of showing these items within our consolidated statements of stockholders' equity
