NEW YORK (Standard&Poor's CreditWire) April 15, 1999--Standard&Poor's today revised its outlook on Apple Computer Inc. to positive from stable. Standard&Poor's also affirmed its single-'B'-plus senior debt and single-'B'-minus subordinated debt ratings on the company. The outlook revision reflects Apple's continuing profitability and improved debt protection measures. The ratings for Cupertino, Calif.-based Apple reflect extremely competitive personal computer (PC) industry conditions and weak market share. Apple has a good position in the education and desktop publishing markets, and has recently recovered market share in the consumer PC market. However, the company's presence in the corporate/enterprise market remains weak. Apple reported 9% year-over-year revenue growth and even stronger unit growth in the quarter ended March 27,
