(4)	Reason for not counting a portion of the voting rights of the shareholders present at the ordinary general meeting of shareholders

Since the adoption or rejection of the proposal was conclusively decided by the exercise of the voting rights prior to the date of this general meeting and the number of voting rights of shareholders in attendance at this general meeting, whose approval or disapproval Mizuho Financial Group was able to confirm, the number of voting rights for approval, disapproval and abstention shown in the above table does not include a portion of those of the shareholders present at the general meeting.

-End-
