While there has been certain media coverage in Japan with respect to a potential stock split of Nippon Telegraph and Telephone Corporation (“NTT”) common stock, NTT has not yet made a determination regarding this matter.

NTT believes that lowering its minimum investment unit is one potentially effective method of encouraging more investors to participate in the market and is currently reviewing this option while considering its recent stock price levels and other factors.

Going forward, NTT will make further public announcements with respect to any relevant disclosures concerning this subject matter as and when required.
