New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes," which requires companies to classify deferred tax assets and liabilities as non-current on the balance sheet. This guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The ASU may be applied either prospectively or retrospectively and early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. 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 annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption of the ASU is 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 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 principles-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.
