There were $64 million of additions to goodwill and $42 million of additions to other intangible assets in the three and six months ended April 30, 2011 related to the purchase of three businesses.
 
Amortization of intangible assets was $28 million and $56 million for the three and six months ended April 30, 2011 and $9 million and $19 million for the same periods in the prior year. In addition, we recorded $3 million of impairments of other intangibles related to an exited business during the three and six months ended April 30, 2011. Future amortization expense related to existing purchased intangible assets is estimated to be $57 million for the remainder of 2011, $95 million for 2012, $78 million for 2013, $68 million for 2014, $57 million for 2015, $50 million for 2016, and $88 million thereafter.
