CONSERVATIVE ACCOUNTING PRINCIPLES, EQUITY VALUATION AND THE IMPORTANCE OF VOLUNTARY DISCLOSURES

Previous theoretical research on voluntary disclosures has commonly viewed accounting information as a simple signalling device, for example indicating «good news» or «bad news». In this paper, voluntary disclosures are considered to provide complementary information in fundamental valuation analysis, as broadly outlined in Ohlson (1989), Brief & Lawson (1992) and Bernard (1993). The research questions are concerned with the importance of voluntary disclosures in a valuation framework of this kind and the expected content and context of such disclosures. The results imply that voluntary disclosures for typical operating companies are expected to be concerned with the prediction of net income for the next period, the long-run future development of the book return on owners» equity, and the accounting cost matching bias of owners» equity. The cost matching bias is caused by conservative valuation principles, and a specific linkage between the book return and the cost matching bias of owners» equity is recognized in the analysis.
