Open tax years

There have been no recent examinations by the U.S. taxing authorities. The Canadian subsidiary was examined by the Canadian taxing authority for the tax years 2009 and 2010 and such examination is now complete. This audit did not result in any material adjustments for such periods. The Company's primary U.S. state income tax jurisdictions are Illinois, Indiana, Michigan, Minnesota, Ohio and New York and its only international jurisdictions are Canada and its province of Ontario. The following table summarizes the open tax years for each major jurisdiction:
