Description of New Accounting Pronouncements Not yet Adopted [Text Block]	12. Recent Accounting Pronouncements In February 2013, the FASB issued Accounting Standards Update No. 2013-02 (ASU 2013-02), which updates the guidance in ASC Topic 220, Comprehensive Income. The objective of ASU 2013-02 is to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments in ASU 2013-02 seek to attain that objective by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. This guidance became effective for us prospectively beginning with our second quarter for fiscal 2013. The adoption of this guidance did not have a material impact upon our financial position or results of operations. 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.
