2. Reasons for the Differences

The differences between the earnings results for Fiscal 2006 and Fiscal 2005 were due mainly to a decrease in Operating Revenues, which was caused by a decrease in Commission Income and Trading Profits, and an increase in Operating Expenses. As a result, Operating Profits, Ordinary Profits and Net Income decreased.
