In 2001, the U.S. government began imposed countervailing and anti-dumping duties ("CADD") on the export of softwood lumber products from Canada, including by the Corporation, and required that the duties be paid - or that a bond be posted equivalent to such duties, which the Corporation did. Under its agreements with its lumber suppliers, the price it paid was reduced according to the applicable CADD rate that was being imposed, but it was further agreed that if the CADD was reversed, that amount would be refunded to the suppliers.
