Our study investigates the relationship between the operating performances of Korean industrial firms and the behavior of discretionary accruals during the period 1994–1997. We hypothesize that the degree of earnings management will depend on the firm operating performances. We construct 10 “cash from operations (CFO)” portfolios to test if there are systematic differences in discretionary accruals across portfolios. Four test methods (a mean accrual test, a correlation test, a regression analysis, and a sign-change test) are used to investigate if operating performances affect discretionary accruals differently. We compare three accrual estimation approaches (two discretionary accruals and total accruals) in testing the earnings management hypotheses. The results support the hypothesis that Korean industrial firms manage earnings. When operating performance is poor, the firms tend to choose income-increasing strategies. In addition, when operating performance is extremely poor, some firms tend to take a big bath, while some of the exceptionally well-performing firms tend to select income-decreasing strategies.
