New Accounting Pronouncement or Change in Accounting Principle, Current Period Disclosures [Abstract]
Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently Issued Accounting Standards Accounting Standards Adopted in 2011: On January 1, 2011, the Company adopted authoritative guidance issued by the Financial Accounting Standards Board ("FASB") on multiple-deliverable revenue arrangements. The guidance amends the criteria for separating consideration in multiple-deliverable arrangements. This guidance establishes a selling price hierarchy for determining the selling price of a deliverable, which is based on: (a) vendor-specific objective evidence; (b) third-party evidence; or (c) estimates. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. In addition, this guidance significantly expands required disclosures related to a vendor's multiple-deliverable revenue arrangements. The adoption of the guidance did not have a material effect on the Company's financial position, results of operations, cash flows or related disclosures. Accounting Standards Not Yet Adopted: In May 2011, the FASB issued authoritative guidance on fair value measurement, which is effective for the Company on January 1, 2012. The guidance resulted in a consistent definition of fair value and common requirements for measurement of and disclosure about fair value between U.S. generally accepted accounting principles and International Financial Reporting Standards. The Company does not expect the adoption of the guidance to have a material effect on its financial position, results of operations, cash flows or related disclosures. In June 2011, the FASB issued authoritative guidance on the presentation of comprehensive income, which is effective for the Company on January 1, 2012. The guidance provides an entity with the option to present 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. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income and a total amount for comprehensive income. The guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in equity. The Company does not expect the adoption of the guidance to have a material effect on its financial position, results of operations, cash flows or related disclosures. Reclassifications: Certain amounts in the prior periods' unaudited condensed consolidated financial statements have been reclassified to conform to the current period's presentation.
