Description of New Accounting Pronouncements Not yet Adopted [Text Block]	New Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-5, "Presentation of Comprehensive Income" ("ASU 2011-5"). ASU 2011-5 amends guidance listed under Accounting Standards Codification ("ASC") Topic 220, "Comprehensive Income," and eliminates the option to present components of other comprehensive income as part of the statement of shareholders' equity. Under the amendments to ASC Topic 220, an entity has the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. While ASU 2011-5 also includes requirements for presentation of reclassification adjustments out of accumulated other comprehensive income, this section was subsequently deferred in December 2011, with the FASB's issuance of ASU 2011-12, "Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05." ASU 2011-5 became effective retrospectively for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company has presented the total of comprehensive income, the components of net income and the components of other comprehensive income in two separate but consecutive statements as a result of the Company's adoption of ASU 2011-5 during the first quarter of 2012. In May 2011, the FASB issued ASU 2011-4, "Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs." ASU 2011-4 amends guidance listed under ASC Topic 820, "Fair Value Measurement," and represents the converged guidance of the FASB and the International Accounting Standards Board on fair value measurement. The guidance clarifies how a principal market is determined, addresses the fair value measurement of instruments with offsetting market or counterparty credit risks, addresses the concept of valuation premise and highest and best use, extends the prohibition on blockage factors to all three levels of the fair value hierarchy and requires additional disclosures. ASU 2011-4 became effective prospectively for interim and annual periods beginning after December 15, 2011. There was no significant impact to the Company's consolidated financial statements as a result of the Company's adoption of ASU 2011-4 during the first quarter of 2012.
