Recent accounting pronouncements [Text Block]
ecent accounting pronouncements. In March 2013, new accounting guidance was issued which clarifies that an entity should release cumulative translation adjustments into net income when the entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity, which is consistent with the Company's prior accounting policy. The new guidance became effective for the Company on February 1, 2014 and did not have a significant impact on the Company's financial statements.

In April 2014, the FASB issued authoritative guidance to change the criteria for reporting discontinued operations. Under the new guidance, only disposals representing a strategic shift in a company's operations and financial results should be reported as discontinued operations, with expanded disclosures. In addition, disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify as a discontinued operation is required. This guidance is effective for the Company beginning February 1, 2015. The guidance applies prospectively to new disposals and new classifications of disposal groups held for sale after the effective date. The Company is currently assessing the impact, if any, the guidance will have upon adoption.
