Abstract: | Increasing the ratio of debt capital to total capital increases leverage or sensitivity of equity earnings per share to changes in pretax earnings on composite capital. If (1) total capital needs, and (2) probabilistic pretax earnings on composite capital are held fixed while the debt ratio is increased, the result is an increased variability of after tax earnings per dollar of equity capital. With the “price” (variability) growing with still further increases in debt ratio, “nonuniform utility of money” concepts are helpful in revealing this growing variability as an “investor barrier” to still greater debt ratios. |
