boards, managers, shareholders and other stakeholders and spells out the rules and procedures and also decision making assistance on corporate affairs By doing this, it also provides the structure through which the company objectives are set and the means of obtaining those objectives and examining the value and the performance of the firms The relative effectiveness of corporate governance has a profound effect on how well a business performs Performance, which shows if the resources of the firm are used efficiently to fulfill the goals of the firm, is crucial in evaluating the overall success of the firm For performance evaluation firms employ both financial and nonfinancial performance criteria Financial performance measures are the starting point for most organizations’ performance measures systems; such as ROA (Return on Assets) and ROE (Return on Equity) are financial performance measures that are most frequently used at academic research 50 The main purpose of the corporate governance mechanism is to provide reassurance to shareholders that managers will achieve results which are in the best interest of the shareholders (Shleifer & Vishny 1997) One way in which this can be achieved is through an effectively structured board that ensures the interests of the managers are in line with those of the shareholders Firm performance indicators based on ROA and ROE reported above show that firm performance in Viet Nam has increased even under the adverse conditions The findings of this study provide evidence that the literature report that good corporate governance is an important factor in determining firm performance Many business failures are due to the board’s inability to address the overall company performance in an effective and consistent manner The reason for this lies in the structure of the board, particularly in relation to the structure of the decision making process which needs to be reformed to enable companies to focus on sustaining high performance in the face of a rapidly changing environment This study reported significant relationships between corporate governance practices of separate leadership structure, a majority of non-executive directors and size of board, and firm performance The growth in the economy, despite the adverse conditions, is partly due to good governance practices adopted by firms in Viet Nam The results about the significance of the relationship between separate leadership structure (CEO duality) and firm performance in Viet Nam based on ROE are supported by agency theory Separation of leadership positions of chairman and CEO is associated with agency theory, applies to this study, because separation of the roles lead to effective monitoring and management, resulting in higher profitability In an environment such as Viet Nam the separation of the two positions is not an important as other countries, because CEO duality has negative effect on financial performance In order to mitigate the risk and increase profitability of firms in Viet Nam, the chairman is not half the CEO Furthermore, as the result of this study, the proportion independent 51 director is as few as possible to firm performance with environment in Viet Nam Thus, the number of members on board does not affect to firm performance From the foregoing analysis, it is evident that corporate governance has an influence on a firm’s performance Indeed, while some of our findings are revealing, clear policy implications should not be lost For enhanced performance of corporate entities, it is important to separate positions of CEO and also firms should be encouraged to maintain proportion independent directors of 40 – 82 percents We would however like to indicate that, in trying to examine the link between corporate governance and firm performance, it would have been appropriate to use a broader spectrum of variables 52 REFERENCES Adams, R., Almeida, H., & Ferreira, D (2005) Powerful CEOs and their impact on corporate performance Review of Financial Studies, 18(4), 1403-1432 Allan Chang Aik Leng (2004) The impact of corporate governance practices on firms‟ financial performance– evidence from Malaysian companies ABI/INFORM Global, 308 Adams, R B and Ferreira, D (2007) A theory of friendly boards, Journal of Finance, 62, 217-250 Abdullah, SN 2004, 'Board Composition, CEO Duality and Performance among Malaysian Listed Companies, ' Corporate Governance, 4(4), 47-61 Benz, M., & Frey, B S (2007) Corporate governance: What can we learn from public governance?
