| Income Taxes [Text Block] | Note 10: Income Taxes The U.S. examination of tax years 2010-2012 commenced during the fourth quarter of 2013. While it is reasonably possible that the examination of 2010-2012 could conclude within the next 12 months, resolution of certain matters is dependent upon a number of factors, including the potential for formal administrative and legal proceedings. As a result, it is not possible to estimate the range of the reasonably possible changes in unrecognized tax benefits that could occur within the next 12 months related to these years, nor is it possible to reliably estimate the total future cash flows related to these unrecognized tax benefits. |
