New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory", which requires that inventory within the scope of the guidance be measured at the lower of cost and net realizable value. Inventory measured using last-in, first-out (“LIFO”) is not impacted by the new standard. This guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted and the prospective transition method should be applied. The Company is currently evaluating the impact of this update on its consolidated financial statements. 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. The guidance is effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. The Company does not expect the adoption of this update to 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 standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which defers the effective date of the new revenue recognition standard by one year. Under the ASU, the new revenue recognition standard is effective for the Company beginning in fiscal 2019. The Company is currently evaluating the impact of this update on its consolidated financial statements.
