Organization and Basis of Presentation [Abstract]
Use of Estimates, Policy [Policy Text Block]	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In February 2013, the Financial Accounting Standards Board ("FASB") issued guidance requiring companies to report, in one place, either on the face of the financial statements or in the notes, information about reclassifications out of accumulated other comprehensive income ("AOCI"). The guidance also requires companies to present current-period reclassifications out of AOCI and other amounts of current-period other comprehensive income ("OCI") separately for each component of OCI on the face of the financial statements or in the notes, whereas companies were previously required to present total changes in AOCI by component on the face of the financial statements or in the notes. For each significant reclassification to net income in its entirety during their reporting period, companies must identify the line item(s) affected in the statement where net income is presented. For any significant reclassifications that are not reclassified directly to net income in their entirety during the reporting period, cross-references to the note where additional details about the effects of the reclassification are disclosed are required. Companies can choose to present this information before tax or after tax, provided that they comply with the existing tax disclosure requirements in Statement of Accounting Standards Codification ("ASC") 220, Comprehensive Income. The guidance is effective for interim and annual reporting periods beginning after December 15, 2012, or the first quarter of 2013 for calendar-year companies and should be applied prospectively. The adoption of this guidance did not affect our business, financial position or results of operations, but may result in additional disclosures. We did not reclassify amounts out of AOCI during the three and nine months ended September 30, 2013. In July 2012, the FASB issued guidance regarding testing indefinite-lived intangible assets for impairment that gives companies the option to perform a qualitative assessment before calculating the fair value of the indefinite-lived intangible asset. Under the guidance, if this option is selected, a company is not required to calculate the fair value of the indefinite-lived intangible unless the entity determines it is more likely than not that its fair value is less than its carrying amount. In October 2012, the FASB issued guidance regarding the application of the qualitative assessment permitted under the Accounting Standards Update 2012-02, issued in July. The guidance requires companies to focus on the significant inputs used to determine the fair value of indefinite-lived intangible assets when companies opt to perform the qualitative assessment. Companies must then evaluate the impact of certain events and circumstances that could have affected those inputs and weigh the identified factors prior to concluding whether the asset is impaired. As significant judgment is applied to conclude that an indefinite-lived intangible asset is not impaired based on a qualitative assessment, the analyses performed by the Company should be supported by clear documentation of the factors considered, including any necessary quantitative calculations. The guidance is effective for interim and annual reporting periods beginning January 1, 2013. The adoption of this guidance did not affect our business, financial position or results of operations. In December 2011, the FASB issued guidance requiring the disclosure of information about offsetting and related arrangements to enable users of financial statements to understand the effect of these arrangements on financial position. The guidance requires the disclosure of both gross information and net information about both instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. In January 2013, the FASB issued an update limiting the scope of the offsetting disclosure requirements established by the original guidance, to certain derivatives (including bifurcated embedded derivatives), repurchase agreements and reverse repurchase agreements, and securities lending and securities borrowing transactions that are eligible for offset on the balance sheet or are subject to an agreement similar to a master netting arrangement, irrespective of whether they are offset on the balance sheet. This update amends the guidance that required companies to apply the requirements to all recognized financial instruments. The original and updated guidance is effective for interim and annual reporting periods beginning January 1, 2013 and retrospectively for all periods presented on the balance sheet. The adoption of this guidance did not affect our business, financial position or results of operations, but may result in additional disclosures (see Note 11).
