This relation is referred as the clean surplus relationship because all changes in assets and liabilities which are unrelated to dividends must pass though the income statement. Generally, this scheme is accepted by accounting theory without connecting it to a user’s perspective on accounting data. While the underlying idea that net stocks of value settle with the creation and distribution of value produces a basic question in an equity valuation context: whether one can create a cohesive theory of a firm’s value that depends on the clean surplus relation to identify a distinct role for each of the three variables: earnings, book value and dividends. Ohlson (1995) resolves the question in a neoclassical framework.In this case, the analysis starts from the assumption that value is equal to the present value of expected dividends (Rubinstein, 1976). Then one can assume the clean surplus relation to replace dividends with earnings and book values in the formula of present value. At the same time, a multiple-date, uncertain model such that earnings and book value act as complementary value indicators is led to by assumption on the stochastic behavior of the accounting data, In a specific way, the main point of the valuation function expresses value as a weighted average of (i) capitalized earnings at present (adjusted for dividends) and (ii) book value at present. Extreme parameterizations of the model produce either capitalized earnings or book value at presents the only value indicators.
