Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Note R - Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued new accounting guidance, Accounting Standards Update ("ASU") No. 2014-09,  Revenue from Contracts with Customers, on revenue recognition. The new standard provides for a single five-step model to be applied to all revenue contracts with customers as well as requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. There is no option for early adoption. For public entities, this ASU is effective for fiscal years and interim periods within those years beginning after December 15, 2016. We are currently evaluating the impact of the new guidance on our consolidated financial statements.
