Recently Adopted Accounting Pronouncements [Abstract]
Description Of Recent Accounting Pronouncements [Text Block]	Recently Adopted Accounting Pronouncements In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update, Testing Goodwill for Impairment (the revised standard). The revised standard is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. The revised standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted provided that the entity has not yet performed its 2011 annual impairment test or issued its financial statements. An entity has the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The Company adopted this update in the fourth quarter of fiscal year 2011, and the adoption of this update did not have an impact on its consolidated results of operations and financial condition. In December 2010, the FASB issued an update which addresses when to perform Step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts. The update modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that impairment may exist. The qualitative factors are consistent with the existing guidance, which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The adoption of this guidance did not have a material impact on the consolidated financial statements. In December 2010, the FASB issued an update which addresses the disclosure of supplementary pro forma information for business combinations. The update requires public entities to disclose pro forma information for business combinations that occurred in the current reporting period, including revenue and earnings of the combined entity for the current reporting period as though the acquisition date for all business combinations that occurred during the year had been as of the beginning of the annual reporting period. If comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business combinations that occurred during the current year had been as of the beginning of the comparable prior annual reporting period. Amendments in this update are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The adoption of this guidance did not have a material impact on the consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, which amends FASB ASC Topic 220, Comprehensive Income. This ASU is intended to increase the prominence of items reported in other comprehensive income in the financial statements by presenting 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. This ASU eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. This ASU does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. This update is effective during interim and annual periods beginning after December 15, 2011. The adoption of this ASU effective January 1, 2012 had no impact on our financial position, results of operations or cash flows. In December 2011, the FASB issued ASU No. 2011-12, which defers certain provisions contained in ASU No. 2011-05, as discussed above, with respect to the requirement to present components of reclassifications of other comprehensive income on the face of the income statement or in the notes to the financial statements. However, this deferral does not impact the other requirements contained in the new standard on comprehensive income as described above. This new guidance was effective for fiscal years and interim periods beginning after December 15, 2011, and was applied retrospectively. We adopted this new guidance on January 1, 2012.

In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update, Testing Goodwill for Impairment (the revised standard). The revised standard is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. The revised standard is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.

If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required.
