Japan-based NTT DoCoMo has entered discussions to acquire up to 20 per cent of VoiceStream Wireless, the flagship of Hutchison Whampoa's mobile-telephone business in the United States.
The deal is worth about US$47 billion, according to Japanese newspaper Nihon Keizai.
Bankers familiar with negotiations said VoiceStream could sell a stake to NTT DoCoMo by issuing new shares.
Hutchison owns about 23 per cent of VoiceStream.
However, this stake would be diluted to about 20 per cent after a new share issue of that size.
The Nihon Keizai yesterday reported NTT DoCoMo would underwrite a private issue of shares in an attempt to acquire a 15 to 20 per cent holding in VoiceStream worth an estimated of 400 billion yen (about HK$29.08 billion) to 500 billion yen.
