Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements [Text Block]	Recent Accounting Pronouncements Accounting Guidance Adopted In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"). The objective of ASU 2013-02 is to improve reporting of reclassifications out of accumulated other comprehensive income ("AOCI") by presenting information about such reclassifications and their corresponding effect on net income primarily in one place either on the face of the financial statements or in the notes. ASU 2013-02 requires an entity to disclose information by component for significant amounts reclassified out of AOCI if the amounts reclassified are required to be reclassified under GAAP to net income in their entirety in the same reporting period. For amounts not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. For public companies, this guidance was effective on a prospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2012. ASU 2013-02 did not change the calculation of or amounts reported as net income and comprehensive income but did change the presentation of the components of AOCI reported in the Company's condensed consolidated financial statements. Accounting Pronouncements Not Yet Effective In February 2013, the FASB issued ASU 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date ("ASU 2013-04"). ASU 2013-04 addresses the diversity in practice related to the recognition, measurement and disclosure of certain obligations which are not addressed within existing GAAP guidance. Such obligations under the scope of ASU 2013-04 include debt arrangements, other contractual obligations, settled litigation and judicial rulings. The guidance requires an entity to measure these joint and several obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors as well as any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 also requires an entity to disclose information about the nature and amount of these obligations. For public companies, ASU 2013-04 is effective on a retrospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company may elect to use hindsight for the comparative periods (if the Company changes its accounting as a result of the adoption of this guidance). Early adoption is permitted. The Company is evaluating the impact that this update may have on its consolidated financial statements.
