In return, the proceeds from the transaction further strengthen our balance sheet and allow us the financial flexibility to invest in our business and return capital to shareholders.”

“Convergys’ IM business has distinguished itself with a record of successful BSS implementations and exceptional professional services for leading international communications carriers,” said Dr. Nobuhiro Endo, President of NEC. “The acquisition of the IM business will enable NEC to bring even greater value and benefits to the service provider industry.”

Convergys expects the transaction to be completed by late second quarter of 2012, subject to the expiration of regulatory waiting periods and other customary closing conditions. Centerview Partners LLC was the financial advisor and Wachtell, Lipton, Rosen & Katz was the legal advisor for Convergys Corporation.

Transaction Impact on Guidance
