Please see the following pages for the details of the business improvement order.
At Mizuho Financial Group and Mizuho Bank, in light of the recent series of IT system failures, we are exercising great care in our implementation of system upgrades and updates. This has entailed examination of the need to upgrade or update individual components, as well as evaluation of the potential impacts on customers and settlement operations in the event of a failure and our measures to prevent such impacts.
We are treating the business improvement order with the utmost seriousness.
Accordingly, we will reassess the need for the scheduled system upgrades and updates, make necessary revisions, and establish and maintain an effective management framework. Our top priority is the stable operation of our IT system,
and we will do all in our power to ensure upgrades and updates proceed steadily and securely. All of our employees will continue to work together towards this goal.
We would like to again sincerely apologize for the significant inconvenience and concern we have caused our customers and other stakeholders as a result of the system failures which have occurred since February 28 this year.
We are now moving forward on investigating the specific causes of the latest system failures, which began with a hardware failure on August 20, and on making improvements. In addition, taking into account the system failures which began on August 20, we will strive to analyze the situation comprehensively through additional angles of investigation and strengthening the overall measures to prevent further incidents which we released on June 15. By doing so, we hope that our customers will be able to continue relying on us with peace of mind.
