Recent accounting pronouncements [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	12. Recent accounting pronouncements In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-08, “Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment” (“ASU 2011-08”). This ASU is intended to simplify how entities test goodwill for impairment and permits an entity to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, if an entity's financial statements for the most recent annual or interim period have not yet been issued. On October 30, 2011, the Company early adopted the provisions of ASU 2011-08 in conjunction with its annual impairment testing. Because the measurement of a potential impairment has not changed, this ASU will not have an impact on our Condensed Consolidated Financial Statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (“ASU 2011-05”). This ASU eliminates the current option to report other comprehensive income and its components in the Statement of Changes in Stockholder's Equity and provides entities with two presentation alternatives. An entity can elect to present items of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. ASU 2011-05 is effective for public entities for fiscal years, and interim periods, within those years, beginning after December 15, 2011. Other than enhanced disclosures, the adoption of ASU 2011-05 is not expected to have a material impact on our Condensed Consolidated Financial Statements. In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs”. The amendments in this ASU generally represent clarification of Topic 820, but also include instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. This update results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and International Financial Reporting Standards (“IFRS”). The amendments are effective for interim and annual periods beginning after December 15, 2011 and are to be applied prospectively. Early application is not permitted. We do not expect the adoption of ASU 2011-04 will have a material impact on our Condensed Consolidated Financial Statements.
