  Telecom Italia SpA said Wednesday that it has reached an agreement with Ardian Inc. over an investment in Infrastrutture Wireless Italiane SpA. 


  The Italian telecommunication company said a consortium led by Ardian would invest in a newly-formed holding company for the transfer of a 30.2% Inwit stake, currently held by Telecom Italia. 


  The consortium will have a 49% stake in the holding company upon closing of the transaction, Telecom Italia said. 


  Telecom Italia said it has also reached an agreement with a vehicle managed and advised by Canson Capital Partners Ltd. to buy a direct Inwit stake of up to 3% of its share capital. 


  Telecom Italia expects to receive implied proceeds of 1.6 billion euros ($1.81 billion), based on an Inwit share price of EUR9.47, excluding dividend. 


  Completion is subject to conditions being met by Sept. 30, Telecom Italia said.
