Notes to Financial Statements
Income Tax Disclosure [Text Block]	*Note 10:* Income Taxes** As of August 31, 2019, we had a liability of $8,998 recorded for gross unrecognized tax benefits (excluding interest) compared to $8,420 as of December 1, 2018. As of August 31, 2019, we had accrued $874 of gross interest relating to unrecognized tax benefits. For the nine months ended August 31, 2019, our recorded liability for gross unrecognized tax benefits increased by $578. On September 28, 2018, the Swiss Parliament approved the Federal Act on Tax Reform and AHV Financing (TRAF). On May 19, 2019, a public referendum was held in Switzerland that approved the federal reform proposals and subsequently announced the TRAF will become effective on January 1, 2020. As TRAF was not enacted as of August 31, 2019, we have not reflected the financial impacts in our Consolidated Financial Statements during the nine months ended August 31, 2019. The Canton of Zurich, where we operate, voted and passed their legislation on September 1, 2019. Accordingly, we will record the combined financial impact of both the federal and cantonal components of Swiss Tax Reform during the fourth quarter of 2019.
