New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In August 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the required disclosures related to an entity’s ability to continue as a going concern. The guidance requires management to evaluate, at each interim and annual reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued, and provide related disclosures. This guidance is effective for annual periods ending after December 15, 2016, and for each annual and interim period thereafter with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on the condensed consolidated financial statements. In June 2014, the FASB issued new guidance on certain share-based payment awards, which clarifies the treatment of performance targets that can be met after the requisite service period of a share-based payment award. Under the new guidance, an entity should treat these performance targets as conditions that affect vesting. This guidance is effective for interim and annual periods beginning after December 15, 2015 with early adoption permitted. The Company does not believe the adoption of this guidance will have a material impact on the condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers," which eliminates the transaction-and industry-specific revenue recognition guidance under current GAAP and replaces it with a principle-based approach for determining revenue recognition. The accounting standard update requires revenue recognition when control of the goods or services transfers to the customer, replacing the existing guidance which requires revenue recognition when the risks and rewards transfer to the customer. Under the new guidance, companies should recognize revenues in amounts that reflect the payment to which a company expects to be entitled in exchange for those goods or services. The guidance is effective for fiscal and interim periods beginning after December 15, 2016. The Company is currently evaluating the impact of this update on its consolidated financial statements. In April 2014, the FASB issued ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity", which includes amendments that change the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization’s operations and financial results. Additionally, ASU 2014-08 requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, expenses and cash flows of discontinued operations. The guidance is effective for fiscal and interim periods beginning after December 15, 2014. The adoption of this update will not have a material impact on the financial statements of the Company.
