Recent accounting pronouncements [Abstract]
Recent accounting pronouncements [Text Block]	Recent accounting pronouncements. In November 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes. The ASU requires entities to classify deferred tax liabilities and assets as noncurrent in a classified statement of financial position. This ASU is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The adoption of this guidance by the Company is not expected to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued authoritative guidance to simplify the balance sheet presentation of debt issuance costs. Under the new guidance, debt issuance costs will be presented as a reduction of the carrying amount of the debt liability. The guidance is effective for the Company beginning February 1, 2016 and will be applied retrospectively for all periods presented. As of October 31, 2015, the Company had $0.2 million of deferred debt issuance costs. The Company does not expect adoption of this guidance to have a material impact on the Company's financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This new standard provides for a single comprehensive model and supersedes most current revenue recognition guidance, including industry specific guidance, and provides for enhanced disclosure requirements. The objective of the new guidance is to improve the consistency, comparability and usefulness to users of financial statements. On April 1, 2015, FASB decided to defer the effective date of the new revenue standard by one year. As a result, public entities would apply the new revenue standard for fiscal years, and interim periods within those years, beginning after December 15, 2017. ASU 2014-09 provides for two implementation methods (1) full retrospective application to each prior period or (2) modified retrospective application with the cumulative effect as of the date of adoption. The Company is evaluating the financial statement impacts of the guidance in this ASU and determining which transition method will be utilized.
