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. In July 2013, the FASB issued ASU 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes ("ASU 2013-10"). ASU 2013-10 permits the Overnight Index Swap ("OIS") Rate, also referred to as the Fed Funds Effective Swap Rate, to be used as a U.S. benchmark for hedge accounting purposes, in addition to London Interbank Offered Rate ("LIBOR") and interest rates on direct U.S. Treasury obligations. The guidance also removes the restriction on using different benchmarks for similar hedges. ASU 2013-10 is effective prospectively for qualifying new or redesignated hedges entered into on or after July 17, 2013. The Company does not expect the adoption of this guidance to have a material effect on its 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. In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"). The objective of this update is to reduce the diversity in practice related to the presentation of certain unrecognized tax benefits. ASU 2013-11 provides that unrecognized tax benefits are to be presented as a reduction of a deferred tax asset for a net operating loss ("NOL") carryforward, a similar tax loss or a tax credit carryforward when settlement in this manner is available under the governing tax law. To the extent such an NOL carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position or the entity does not intend to use the deferred tax asset for this purpose, the unrecognized tax benefit is to be recorded as a liability in the financial statements and should not be netted with a deferred tax asset. ASU 2013-11 is effective for public companies for fiscal years beginning after December 15, 2013 and interim periods within those years. The guidance should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Early adoption and retrospective application are permitted. The Company is evaluating the impact that this update may have on its consolidated financial statements.
