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 GAAP. The new standard is effective for the Company in the first quarter of 2018, with early adoption permitted in the first quarter of 2017. The standard permits the use of either the retrospective or cumulative effect transition method. At this time, we have not selected a transition method, nor have we determined if we will adopt early. We are currently evaluating the effect that ASU 2014-09, and its subsequent amendments discussed below, will have on our consolidated financial statements and related disclosures.
