Notes to Financial Statements
Accounting Changes [Text Block]	18. Deferred Income Taxes Reclassification In November 2015, the Financial Accounting Standards Board issued Accounting Standards Update No. 2015-17, “Income Taxes” which simplifies the balance sheet presentation of deferred income taxes. We have adopted the provisions of the standard for our 2015 consolidated financial statements including retroactive reclassification of the $3.2 million current deferred income tax asset as of December 31, 2014 to a noncurrent deferred income tax liability. This reclassification does not have a significant impact on our consolidated balance sheets.
