New Accounting Pronouncements [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	New Accounting Pronouncements In February 2013, the FASB issued ASU No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" that requires entities to disclose either on the face of or in the notes to the financial statements the effects of reclassifications out of AOCI. For items reclassified out of AOCI and into net income in their entirety, entities must disclose the effect of the reclassification on each affected net income item. For items that are not reclassified in their entirety into net income, entities must provide a cross reference to other required U.S. GAAP disclosures. This ASU does not change the items currently reported in other comprehensive income and is effective for annual reporting periods beginning after December 15, 2012 and interim periods within those years. The adoption of these provisions did not have a material impact on the consolidated financial statements of the Company.
