The Company has significant operations in the United States and Canada and to a lesser extent in various other international jurisdictions. Tax years that remain subject to examination by major tax jurisdictions vary by legal entity but are generally open in the U.S. for the tax years ending after 2015 and outside the U.S. for the tax years ending after 2013.
