RECENT ACCOUNTING PRONOUNCEMENTS [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	12. RECENT ACCOUNTING PRONOUNCEMENTS In May 2011, the FASB issued ASU 2011-04 relating to fair value measurement (FASB ASC Topic 820), which amends current guidance to achieve common fair value measurement and disclosure requirements in U.S. GAAP and International Financial Reporting Standards. The amendments generally represent clarification of FASB ASC 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 pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements. In June 2011, the FASB issued ASU 2011-05 which provides new guidance on the presentation of comprehensive income (FASB ASC Topic 220) in financial statements. Entities are required to present total comprehensive income either in a single, continuous statement of comprehensive income or in two separate, but consecutive, statements. Under the single-statement approach, entities must include the components of net income, a total for net income, the components of other comprehensive income and a total for comprehensive income. Under the two-statement approach, entities must report an income statement and, immediately following, a statement of other comprehensive income. Under either method, entities must display adjustments for items reclassified from other comprehensive income to net income in both net income and other comprehensive income. The provisions for this pronouncement are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements. In September 2011, the FASB issued ASU 2011-08 relating to testing goodwill for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test goodwill for impairment. The amendments permit 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. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements. In December 2011, the FASB issued ASU 2011-12, which defers changes in Update 2011-05 that relate to the presentation of reclassification of adjustments for entities that report items of other comprehensive income. This pronouncement is effective at the same time as ASU 2011-05 for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning January 1, 2012. The adoption of this pronouncement did not have a material effect on our consolidated financial statements. In July 2012, the FASB issued ASU 012-02, relating to testing intangible assets and long-lived assets for impairment (FASB ASC Topic 350), which amends current guidance to simplify how entities test indefinite-lived intangible assets for impairment. The amendments permit 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 impairment test described in Topic 350. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. This pronouncement is effective for annual and interim impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this pronouncement for our fiscal year beginning September 15, 2012. The adoption of this pronouncement will not have a material effect on our consolidated financial statements.
