Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block] | 15. RECENT ACCOUNTING PRONOUNCEMENTS In December 2010, FASB issued ASU 2010-28 “Intangibles - Goodwill and Other (Topic 350)” (ASU 2010-28). Topic 350 is amended to clarify the requirement to test for impairment of goodwill. Topic 350 has required that goodwill be tested for impairment if the carrying amount of a reporting unit exceeds its fair value. Under ASU 2010-28, when the carrying amount of a reporting unit is zero or negative an entity must assume that it is more likely than not that a goodwill impairment exists, perform an additional test to determine whether goodwill has been impaired and calculate the amount of that impairment. The modifications to ASC Topic 350 resulting from the issuance of ASU 2010-28 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2010. The adoption of the standard did not have a material impact on our consolidated results of operations and financial condition. In December 2010, FASB issued ASU 2010-29 “Business Combinations (Topic 805) - Disclosure of Supplementary Pro Forma Information for Business Combinations” (ASU 2010-29). This standard update clarifies that, when presenting comparative financial statements, SEC registrants should disclose revenue and earnings of the combined entity as though the current period business combinations had occurred as of the beginning of the comparable prior annual reporting period only. The update also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. ASU 2010-29 is effective prospectively for material (either on an individual or aggregate basis) business combinations entered into in fiscal years beginning on or after December 15, 2010. The adoption of the standard did not have a material impact on our consolidated financial statements. In June 2011, FASB issued ASU 2011-05, “Comprehensive Income (Topic 220) – Presentation of Comprehensive Income” (ASU 2011-05). This standard update requires an entity 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. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of stockholders’ equity. ASU 2011-05 is effective for the interim and annual periods beginning after December 15, 2011. The adoption of the standard did not have a material impact on our consolidated financial statements. In September 2011, FASB issued ASU 2011-08, “Intangibles-Goodwill and Other (Topic 350) – Testing Goodwill for Impairment”. ASU 2011-08 provides companies with a new option to determine whether or not it is necessary to apply the traditional two-step quantitative goodwill impairment test in ASC 350, Intangibles – Goodwill and Other. Under ASU 2011-08 companies are no longer required to calculate the fair value of a reporting unit unless it determines, on the basis of qualitative information, that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. ASU 2011-08 is effective for periods ending after December 15, 2011; however, early adoption is permitted for periods ending after September 15, 2011. The adoption of the standard did not have a material impact on our consolidated financial statements. In February 2013, FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”. The objective of this ASU is to improve reporting by requiring entities to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in the statement of operations. The amendments in this ASU are required to be applied retrospectively and are effective for reporting periods beginning after December 15, 2012. We do not anticipate the adoption to have any impact on our consolidated financial statements other than revising the presentation relating to items reclassified from accumulated other comprehensive income to the statement of income and comprehensive income (loss).
