Overview of current system and reason for adoption

The Company is a company with an Audit & Supervisory Board and has implemented various measures to strengthen its corporate governance. In 2002, efforts to reform governance included the introduction of a Corporate Officer system along with a significant reduction in the number of Directors for the purpose of clearly separating management’s monitoring and execution functions. In addition, to fortify the system for boosting shareholders’ confidence, we shortened the term of office of Directors from 2 years to 1 year and actively invited the participation of Outside Directors.
In addition, the Company has established 3 committees acting as advisory organizations to the Board of Directors (the Nomination Advisory Committee, the Compensation Advisory Committee, the Corporate Governance Committee) to strengthen our management supervision functions.
Further, TDK established “TDK Basic Policy on Corporate Governance”. The policy request to elect Independent Outside Directors which account majority of the Directors and to assign an Independent Outside Director as the chair of the Board of Directors in principle. TDK complies them.

In short, the Company has always believed it can realize a system to continuously ensure sound, compliant and transparent management through the introduction of a new framework that strengthens corporate governance based on its Audit & Supervisory Board System.
