New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In June 2014, the FASB issued ASU 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period". The new guidance requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The guidance also clarifies that the performance target should not be reflected in estimating the grant-date fair value of the award. This guidance is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. The adoption of this update did not have a material impact on the financial statements of the Company. 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 new guidance 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. In April 2015, the FASB proposed a one-year deferral of the effective date of the new revenue standard. Under the proposal, the standard would be effective for fiscal and interim periods beginning after December 15, 2017, with early adoption permitted. 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 did not have a material impact on the financial statements of the Company.
