Description of New Accounting Pronouncements Not yet Adopted [Text Block]	14. Recent Accounting Pronouncements In April 2014, the FASB issued Accounting Standards Update No. 2014-08 (ASU 2014-08), which updated the guidance in ASC Topic 205, Presentation of Financial Statements, and ASC Topic 360, Property, Plant and Equipment. The amendments in ASU 2014-08 change the criteria for reporting discontinued operations for all public and nonpublic entities. The amendments also require new disclosures about discontinued operations and disposals of components of an entity that do not qualify for discontinued operations reporting. This guidance will become effective for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years, and therefore will become effective for us as of the beginning of our 2016 fiscal year. The adoption of this guidance is not expected to have a material impact upon our financial condition or results of operations. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), which creates ASC Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, ASU 2014-09 supersedes the cost guidance in Subtopic 605-35, Revenue Recognition—Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs—Contracts with Customers. In summary, the core principle of Topic 606 is to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and early application is not permitted. Therefore the amendments in ASU 2014-09 will become effective for us as of the beginning of our 2018 fiscal year. The Company is currently assessing the impact of implementing the new guidance. In January 2015, the FASB issued Accounting Standards Update No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates the concept of reporting extraordinary items, but retains current presentation and disclosure requirements for an event or transaction that is of an unusual nature or of a type that indicates infrequency of occurrence. Transactions that meet both criteria would now also follow such presentation and disclosure requirements. For all entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after 15 December 2015. Early adoption is permitted; however, adoption must occur at the beginning of an annual period. Therefore the amendments in ASU 2015-01 will become effective for us as of the beginning of our 2017 fiscal year. The adoption of this guidance is not expected to have a material impact upon our financial condition or results of operations.
