董事会
因为董事们行使控制和管理公司的权力，但是公司（至少理论上）是为股东利益服务的，故法律明确定义的董事所能履行的职责。这些职责是信托责任，类似于法律赋予信托职位的职责：代理人和受托人。

FSS acts as the executive supervisor for the FSC and principally carries out examination of financial institutions along with enforcement and other oversight activities as directed or charged by the FSC.The Financial Services Commission (FSC) is a central public administration agency falling under the jurisdiction of the Office of the Prime Minister, and is charged with the deliberation and determination of financial policies and other important matters of financial supervision – such as the supervision, examination, and sanctioning of financial institutions, and authorization and licensing of financial institutions. Pursuant to the relevant legal provisions, the FSC may direct and supervise the operations of the FSS. In addition to its inherent responsibilities of supervising and sanctioning financial institutions, the FSS supports the operations of the FSC and its adjoined Securities & Futures Commission, and executes those FSC duties which are entrusted by the FSC to the FSS. (Article 37, Act on the Establishment, etc. of Financial Services Commission)  Prior to February 2008, the law provided that the Chairman of the Financial Supervisory Commission (the predecessor to the Financial Services Commission) be concurrently appointed as the Governor of the FSS, with the FSS directly assisting the operations of the commission. The revision of the Act in February 2008 clearly distinguishes the policy-making function of the FSC and the supervisory enforcement function of FSS, and provides that different persons be assigned to head each organization to ensure more effective checks and balances (Article 29 (2) of the Act). The revision also provides that the Governor of FSS may, as an ex-officio member of the FSC, request to the FSC chairman that matters necessary within the scope of FSS operation be included in the commission’s agenda.
