Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Error Corrections [Text Block]	Note 2. Recently Issued Accounting Pronouncements During July 2012, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment”. The revised standard is intended to reduce the cost and complexity of testing indefinite-lived intangible assets other than goodwill for impairment by providing entities with an option to perform a "qualitative" assessment to determine whether further impairment testing is necessary. The revised standard allows an entity first to assess qualitative factors to determine whether events and circumstances indicate that it is more likely than not that an indefinite-lived intangible asset is impaired. If it is more likely than not that the asset is impaired, the entity must calculate the fair value of the asset, compare the fair value to its carrying amount, and record an impairment charge, if the carrying amount exceeds fair value. However, if an entity concludes that it is not more likely than not that the asset is impaired, no further action is required. The qualitative assessment is not an accounting policy election. An entity can choose to perform the qualitative assessment on none, some, or all of its indefinite-lived intangible assets. Moreover, an entity can bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to the quantitative impairment test, and then choose to perform the qualitative assessment in any subsequent period. The revised standard is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company does not expect the adoption of this standard to have a material impact on its financial position or results of operations. During September 2011, the FASB issued ASU No. 2011-08, “Testing Goodwill for Impairment” (“ASU 2011-08”). ASU 2011-08 is intended to simplify the testing of goodwill for impairment by permitting 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, which is currently required for all companies that report goodwill. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, although early adoption is permitted. The Company has adopted this standard, which had no impact on its financial position or results of operations.
