Pendergast, Inc., has no debt outstanding and a total market value of $180,000. Earnings before interest and taxes, EBIT, are projected to be $23,000 if economic conditions are normal. If there is strong expansion in the economy, then EBIT will be 20 percent higher. If there is a recession, then EBIT will be 30 percent lower. Pendergast is considering a $75,000 debt issue with an interest rate of 7 percent. The proceeds will be used to repurchase shares of stock. There are currently 6,000 shares outstanding. Pendergast has a tax rate of 35 percent.
