Certain items, pre-tax, for the six months ended March 31, 2012 include charges of $12 million related to global restructuring and $2 million for environmental reserves and legal settlements. For the three and six months ended March 31, 2012, the impact of tax certain items was $1 million and $2 million, respectively. Certain items, pre-tax, for the three and six months ended March 31, 2011 primarily relate to global restructuring charges as discussed in Note I.
