Description of New Accounting Pronouncements Not yet Adopted [Text Block]	12. Recent Accounting Pronouncements In July 2013, the FASB issued Accounting Standards Update No. 2013-11 (ASU 2013-11), which updated the guidance in ASC Topic 740, Income Taxes. The amendments in ASU 2013-11 generally provide guidance for the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The guidance requires an unrecognized tax benefit to be presented as a decrease in a deferred tax asset where a net operating loss, a similar tax loss, or a tax credit carryforward exists and certain criteria are met. This guidance will become effective for us as of the beginning of our 2015 fiscal year and is consistent with our present practice. 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 that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange 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.
