  1. Notes. The independent variable of columns (1) and (2) is operating income for firm i at fiscal year-end. Column (2) shows the results with the inclusion of control variables on the basis of column (1). The independent variable of columns (3) and (4) is net income for firm i at fiscal year-end. Column (4) shows the results with the inclusion of control variables on the basis of column (3). Numbers in parentheses are t-statistics based on standard errors clustered by firm when we control for year and industry effects
  2. a, b, and c denote statistical significance at the 1%, 5%, and 10% levels, respectively
