NEW YORK (Standard&Poor's) June 18, 2002--Standard&Poor's said today that UnitedHealth Group Inc.'s plan to acquire AmeriChoice Corp. will have no effect on the ratings at this time. Valued at $560 million, the acquisition will be a 100% stock transaction, is subject to regulatory approval, and is expected to close in the fourth quarter of 2002.
