QUESTION 1 Which of the following statements is FALSE? Using market values rather than book values is preferable when computing a weighted-average cost of capital (WACC). O O A WACC is found by taking the weighted-average of the cost of debt capital and the cost of equity capital. The WACC will be higher when the company has a greater systematic risk. The WACC will always be higher than the cost of equity capital since it may involve debt which is riskier than equity.
