Recently Issued Accounting Standards [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	2. Recently Issued Accounting Standards In December 2011, the FASB amended the guidance in ASC 210 related to disclosures about offsetting assets and liabilities. The amendments would require an entity to disclose information about financial instruments and derivative instruments that are either offset subject to ASC 210-20-45 or ASC 815-10-45, or subject to enforceable master netting arrangements or similar arrangements. We will be required to adopt this guidance beginning with our interim financial statements for the three months ended March 31, 2013. The adoption of this accounting standard is not expected to have a material impact on our financial statements. In September 2011, the FASB amended the guidance in ASC 350-20 on testing goodwill for impairment. Under the revised guidance, entities testing goodwill for impairment have the option of performing a qualitative assessment before calculating the fair value of the reporting unit. If entities determine, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. We will be required to adopt this guidance beginning with interim financial statements for the three months ending March 31, 2012. The adoption of this accounting standard will not have a material impact on our financial statements, rather it may change our future approach for annual goodwill testing. In June 2011, the FASB issued new guidance under ASC 220 regarding the presentation of comprehensive income in financial statements. An entity has the option to present the components of net income and other comprehensive income (loss) either in a single continuous statement or in two separate but consecutive statements. We will be required to adopt this guidance beginning with our interim financial statements for the three months ending March 31, 2012. Separately, in November 2011, the FASB amended a portion of this guidance to defer proposed changes to the presentation of reclassification adjustments. The adoption of this accounting standard will change the presentation of other comprehensive income (loss) in our financial statements. In September 2009, new accounting guidance under ASC 605 related to revenue arrangements with multiple deliverables was issued. The guidance addresses the unit of accounting for arrangements involving multiple deliverables, how arrangement consideration should be allocated to the separate units of accounting and eliminates the criterion that objective and reliable evidence of fair value of any undelivered items must exist for the delivered item to be considered a separate unit of accounting. Effective January 1, 2011, we prospectively adopted this standard for revenue arrangements entered into or materially modified after the adoption date. The adoption of this accounting standard did not have a material impact on our financial statements. In September 2009, new accounting guidance under ASC 985 was issued regarding tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. Effective January 1, 2011, we prospectively adopted this standard for revenue arrangements entered into or materially modified after the adoption date. The adoption of this accounting standard did not have a material impact on our financial statements.
