NEW YORK, Jan. 22 -- AT&T Wireless and NTT DoCoMo said today that they have commenced their previously announced strategic alliance to develop mobile multimedia services on a global-standard, high-speed wireless network. NTT DoCoMo, one of Japan's leading communications companies, today acquired shares of AT&T preferred tracking stock, equivalent to 406 million shares of AT&T Wireless tracking stock (an approximate 16 percent economic interest) for about $9.8 billion. In addition, NTT DoCoMo has acquired five-year warrants to purchase the equivalent of an additional 41.7 million shares of AT&T Wireless tracking stock at $35 per share. AT&T reduced its retained interest in the AT&T Wireless Group by 178 million shares and received $20.50 per share from NTT DoCoMo. The balance of the 406 million shares came from the issuance of 228 million new primary shares of AT&T Wireless tracking stock at $27.00 per share.As a result of this transaction, excluding the warrants and prior to the spin-off of AT&T Wireless, AT&T retains a 70 percent economic interest in AT&T Wireless' operating results. About 14 percent of the economic interest in AT&T Wireless' operating results will continue to be represented by the existing AT&T Wireless tracking stock publicly traded on the New York Stock Exchange. This world-class alliance will bring an exciting new generation of mobile multimedia services to AT&T Wireless customers much more quickly than we anticipated even six months ago, said John D. Zeglis, chairman and CEO of AT&T Wireless. Millions of AT&T Wireless customers will soon have the benefit of a high-performing mobile Internet built-in to the fabric of everyday life. AT&T Wireless is creating a new, wholly owned subsidiary to develop multimedia applications for its current network and a new, high-speed wireless network built to global standards. Both companies will share technical resources and support staffing of the new unit.Polatis Announces 2 Million in BackingCAMBRIDGE, England, Jan. 22 -- Fiber optic switch developer Polatis Ltd. has announced a 2 million (Pounds) investment package from a venture capital syndicate.
