MORGAN STANLEY DEAN WITTER DISCLOSES IMPACT ON NET INCOME
NEW YORK, September 1, 1998 -- Morgan Stanley Dean Witter & Co. (NYSE:MWD)
announced today that, while the entire Firm has continued to perform extremely
well, it has been affected by the difficult conditions in global capital
markets. Certain credit sensitive trading activities, and a loss in connection
with an institutional leveraged emerging markets portfolio, will cause an
estimated reduction in consolidated net income of $110 million for the fiscal
quarter ended August 31, 1998.
Morgan Stanley Dean Witter is a global financial services firm and a market
leader in securities, asset management and credit and transaction services. The
Company has offices in New York, London, Tokyo, Hong Kong, and other principal
financial centers around the world and has 411 securities branch offices
throughout the United States.
