Yamaha Corp. said Wednesday it has revised downward its group earnings forecast for the first half and full 2001 business year due to sales declines in musical instruments and information technology-related devices.

For the first half that ended Sept. 30, Yamaha expects a net profit of 6.5 billion yen, down from the previous projection in May of 8.5 billion yen.

Pretax profit for the six-month period has been revised down to 7.5 billion yen from 10 billion yen and sales have been downgraded 250 billion yen from 270 billion yen.

For the full year through March 31, the company estimates a consolidated net profit of 13 billion yen, revised down from 15 billion yen, and a pretax profit of 15 billion yen, down from 21 billion yen, on sales of 515 billion yen, down from 550 billion yen.
