This book links accounting, strategy and valuation to address the challenge of valuing a firm's intellectual capital. Accounting-based valuation models have recently regained popularity in research and practice. However, few models attempt to integrate non-financial information into their valuation functions. At the same time, strategy research has identified organizational knowledge and the intellectual capital of a firm as the prime resources for competitive advantage. The conservatism of financial accounting standards statements, however, results in financial statements that fail to capture the true value of firms' intangible assets. The author presents a measure of earnings derived from intellectual capital, that captures the missing intangible information. He further presents a model to integrate this information into a comprehensive accounting-based valuation function. The empirical tests provide evidence that suggests that the value relevance of the earnings measure of intellectual capital is higher than that of any other income measure. The proposed valuation model also shows a higher information content than alternative models. This book offers a methodology of integrating intangible information into valuation. It is useful for both professionals and students in accounting and finance.
