Curtailment of employee benefit plan

During the three and six months ended March 31, 2012, the Company incurred curtailments and settlement losses (gains) in the U.S. and foreign employee benefit plans as a result of the sale of the Supermetals business and the freezing of two defined benefit plans in foreign affiliates. The net impact of these items was a $1 million loss during both the three and six months ended March 31, 2012. During the first six months of fiscal 2011, the Company incurred a curtailment in one of its foreign employee benefit plans as a result of the action taken in the 2009 Global Restructuring Plan. Associated with this curtailment, the Company recognized a $1 million benefit in the first six months of fiscal 2011.
