Director Nomination Policy
The Company aims to bring about positive change in the world and realize a society in which sei-katsu-sha can flourish and live active lifestyles of their choosing. To accomplish these goals, we create new value for sei-katsu-sha by harnessing the creativity of employees and the integrative capabilities of teams in which individuals assert their creativity and respect that of others to further their mutual growth. This emphasis has led the Hakuhodo DY Group to become an organization boasting a level of diverse creative minds that is unprecedented on a global scale.
We take a similar approach toward the Board of Directors. With due consideration paid to the overall balance of insight, experience, and skills of directors, we seek to nominate internal directors that are highly knowledgeable about the Group’s operations along with multiple outside directors with extensive experience and wide-ranging insight. By assembling a unique and creative team on the Board of Directors, we look to ensure that the Board is able to contribute effectively to higher corporate value for the entire Group

Note: This chart is not intended to reflect all of the skills of the Company’s directors and Audit & Supervisory Board members.
*1 Sei-katsu-sha Insight is the foundation of our thinking and planning. It reminds us that consumers have heartbeats and are more than just shoppers performing an economic function. These unique, autonomous individuals that we refer to as sei-katsu-sha live in an increasingly diverse society. We believe that deeper insight into their lives is the source from which new value springs. That is why we make it our business to know sei-katsu-sha better than anyone else and to use that knowledge to make a stronger bridge between advertisers and sei-katsu-sha as well as media.
*2 Commitment to Partnership is the way we do business, the starting point for all business activities. From the standpoint of sei-katsu-sha, we pay constant, careful attention to the needs of our clients and of media companies. We believe that engaging in dialogue and acting together are the best ways to find the solutions to those needs. As our clients’ and media companies’ partner, our aim is to build strong, long-lasting relationships. By working together over the long term, we are better able to provide durable and coherent solutions to our partners.
*3 Under this policy, we regard our employees as extremely valuable stakeholders. The minds of our employees are what allow us to produce ideas. For this reason, we place importance on employee satisfaction and are making particular efforts to respect individuality, develop personal creativity, and enhance our teamwork capabilities. These efforts ultimately help us improve our level of customer satisfaction.
