The purpose of this dissertation is to reconsider the role and significance of the balance sheet, whose position has become ambiguous in recent years, from the viewpoint of corporate value evaluation. It examined the actual changes in standards that seemed to improve the information displayed on the balance sheet and how they were positioned in terms of corporate valuation. As a result, we pointed out that the role of the current balance sheet can be expected to be useful for estimating the cost of capital by disclosing corporate risk information.
