ASU 2014-09 Revenue from Contracts with Customers [Member]
Interim Statement Presentation [Line Items]
New Accounting Pronouncements, Policy [Policy Text Block]	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In April 2015, the FASB issued an exposure draft to propose a delay of the effective date for one year, which would make the effective date for the Company the first quarter of 2018. The standard permits the use of either the retrospective or cumulative effect transition method. At this time we have not selected a transition method. We are currently evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures.

Interim Statement Presentation [Line Items]
New Accounting Pronouncements, Policy [Policy Text Block]	In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying value of the debt liability. ASU 2015-03 is effective for the Company in the first quarter of 2016, with early adoption permitted, and retrospective application required. The Company has chosen to adopt the standard early, effective in the first quarter of 2015. The adoption of ASU 2015-03 did not have a material impact on our condensed consolidated financial statements. Refer to Note (9) for further information regarding debt issuance costs.
