Corporate governance

Despite increased regulation and disclosure, serious doubts remain about how effective corporate governance rules are in achieving their basic objectives of ensuring that directors manage– and are seen to manage– their companies in accordance with the shareholders’ interests. Huge efforts have been made to ensure that directors’ remuneration is aligned to the long-term health of the company rather than to the attainment of shortterm goals. But academic and other studies continue to show that the link between long-term corporate performance and directors’ pay is still far from perfect.

Weaknesses in risk management may be either technical, due to poorly designed risk management processes, or operational in that they relate to a failure in implementing otherwise sound procedures. Both technical and operational weaknesses were features of the financial crisis. In particular, the research found the defects listed in the next slide.

Regulation

Structural reforms such as the enforced separation of retail and investment banking activities, or the breaking up of large institutions, have been at the centre of the debate around fixing the financial crisis. Measure to control excessive bonuses and remuneration packages that reward excessive risk taking are to be curtailed.
