[1] At February 29, 2012, we also performed an interim impairment test of Ibero's trademarks, which resulted in a $20 million impairment charge, based on the reduction of revenues primarily as a result of slower than anticipated Ibero capacity growth and a lower estimated royalty rate. At August 31, 2012, Ibero's remaining trademark carrying values are not significant.
