Process for Identifying Key Sustainability Areas

We identify key sustainability areas in response to the expectations and demands that a variety of stakeholders have for financial institutions (and/or Mizuho in particular) in regards to the sustainable development of the economy, industry, and society, and based on medium– to long–term impact on our corporate value, as well as the strategic importance and affinity of such areas with our strategies. In identifying these areas, we consider which issues we should focus on from the perspective of medium– to long–term risks and opportunities for our in–house companies, units, and groups, and, after deliberation by the Executive Management Committee, the identified areas are confirmed through resolution by the Board of Directors. The key sustainability areas will be revised each fiscal year and incorporated into our business plans based on changes in the business environment.
