New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted Accounting Pronouncements [Text Block]	In May 2011, the FASB issued ASU 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (IFRS)." ASU 2011-04 represents converged guidance between U.S. GAAP and IFRS resulting in common requirements for measuring fair value and for disclosing information about fair value measurements. This new guidance is effective for fiscal years beginning after December 15, 2011 and subsequent interim periods. The requirements of ASU 2011-04 did not have a material impact on the Company's condensed consolidated financial statements. The revised disclosure requirements are reflected in Note 9. In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income." ASU 2011-05 requires the Company to present components of other comprehensive income and of net income in one continuous statement of comprehensive income, or in two separate, but consecutive statements. The option to report other comprehensive income within the statement of equity has been removed. This new presentation of comprehensive income is effective for fiscal years beginning after December 15, 2011 and subsequent interim periods. The revised presentation requirements are reflected in the Condensed Consolidated Statements of Comprehensive Income. In December 2011, the FASB issued ASU 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." The revised amendments defer the presentation in the financial statements of reclassifications out of accumulated other comprehensive income for annual and interim financial statements. The deferral is effective for fiscal years beginning after December 15, 2011 and subsequent interim periods. The revised presentation requirements are reflected in the Condensed Consolidated Statements of Comprehensive Income. In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment.” This revised standard provides entities with the option to first use an assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If a conclusion is reached that reporting unit fair value is not more likely than not below carrying value, no further impairment testing is necessary. This revised guidance applies to fiscal years beginning after December 15, 2011, and the related interim and annual goodwill impairment tests. The requirements of ASU 2011-08 did not have a material impact on the Company's condensed consolidated financial statements.
