Wärtsilä implements a single-tier governance model, by which management of the Wärtsilä Group is the responsibility of the General Meeting of shareholders, the Board of Directors, and the President & CEO. Their duties are for the most part defined by the Finnish Companies Act. The General Meeting of shareholders elects the Board of Directors and auditor. The Board of Directors is responsible for the strategic management of the company, and is assisted in its work by the Board Committees. The Board appoints the President & CEO. He is in charge of the operative, day-to-day management of the company, with support from the Board of Management.
