An accounting-based valuation approach to valuing corporate governance in Taiwan

Abstract

We estimate the proportion of firm value that is related to governance mechanisms in a cointegrated system based on the Feltham and Ohlson (1995) accounting-based valuation model. Using a comprehensive set of 32 governance measures in five categories for Taiwan firms, we find that governance measures related to ownership structure and the divergence between cash flow rights and control rights capture variations in stock prices over time. Controlling for book value, net operating assets, and abnormal operating earnings which account for up to 59% of firms' equity value over time, the governance measures in addition track at least 39% of the equity value of these firms. We further identify that the shareholdings of board directors and supervisors, shareholdings of the controlling family, the critical control level of a firm, and the voting rights of the largest shareholder for ultimate control are sufficient governance measures to track changes in firm value. Our results shed some light on the extent of the equity value that can be generated by a firm's governance practices and the types of corporate governance mechanisms that are especially important for firms with similar ownership structure and controls. © 2010.
