The reasons the company gives
The company's own explanation, not something inferred from the numbers.The main factor behind the increase in operating income was a reduction in advertising and promotional expenses following a review of spending. In the package business, development work on a large project received in the previous fiscal year expanded in the second half, while new orders and additional development orders remained sluggish. In the systems integration business, unit prices, man-hours and revenue exceeded plan, but segment profit declined because higher personnel expenses related to improved employee compensation more than offset these gains.
