Recent Accounting Pronouncements [Text Block]	2. Recent Accounting Pronouncements In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”), which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, ASU 2013-02 requires an entity to present, either on the face of the income statement or in the notes to financial statements, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The amendments in ASU 2013-02 do not change the current requirements for reporting net income or other comprehensive income in financial statements. For public entities, the amendments in ASU 2013-02 are effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this guidance concerns disclosure only and our adoption of this new provision of ASU 2013-02 on January 1, 2013 did not have an impact on our condensed consolidated financial statements.
