Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 14. Recent Accounting Pronouncements In September 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that amends the accounting guidance on goodwill impairment testing. The amendments in this accounting standard update are intended to reduce complexity and costs by allowing an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it should calculate the fair value of a reporting unit. The amendments also improve previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendments in this accounting standard update are effective for interim and annual goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The adoption of this accounting standard update will not have an impact on our consolidated financial position, results of operations, or cash flows, as it is intended to simplify the assessment for goodwill impairment.
