Ideally, an analyst would use the YTM of a firm’s existing debt as the pretax cost of new debt. When a firm’s debt is not publicly traded, however, a market YTM may not be available. In this case, an analyst may use the yield curve for debt with the same rating and maturity to estimate the market YTM. If the anticipated debt has unique characteristics that affect YTM, these characteristics should be accounted for when estimating the pretax cost of debt. The cost of debt is the market interest rate (YTM) on new (marginal) debt, not the coupon rate on the firm’s existing debt. If you are provided with both coupon and YTM on the exam, you should use the YTM. |
