Japan's Toshiba Corp. said on Monday it expects a group pre-tax profit of 110 billion yen (1.1 billion dollars) in the current fiscal year ending March 31, a downward revision from an earlier forecast of 130 billion yen. The downward revision was due to poor chip business, the Japanese electric machinery manufacturer said. Toshiba has a tie-up relationship with leading European companies, including Siemens in Germany in semiconductors and Italy's Olivetti in computers. Toshiba also said its sales were revised downward to 5.86 trillion yen from earlier estimate of 5.87 trillion yen, while its group net profit was also revised to 45 billion yen from an earlier forecast of 50 billion yen.
