Fujitsu has lowered its parent net profit forecast for the year to March 31, 1991, to $616.2m from the $663m estimated in May. The company says that while domestic demand is healthy, the outlook for the coming year is less clear, and uncertainties in the Middle East raised the possibility of higher interest rates and a stronger yen. Current income forecasts remain unchanged at $1,053, representing an increase of 6% on the previous year, and the sales forecast has been increased to $18,330m from the $18,096m that was estimated by Fujitsu in May.
