(d) Find the value of the hedged firm that issues an optimally chosen quantity of safe debt. (10 points) Answer: Maximum debt that the firm can issue is such that its cash flow can cover debt repayments (principal plus interest) and taxes. Safe debt has a yield of 0.05. Therefore, total payments must satisfy 1.05F + 0.4 · (350 − 300 − F · 0.05) ≤ 350 implying that the highest permissible F = 320.388. Therefore, Value of firm = 1 · [350 − .4 · 50 + .4 · 0.05 · 320.388] = 320.388 1.05
In the remaining parts assume that bankruptcy costs are $20 per unit of gold. (e) If the firm issues $250 of risky debt, find the yield on the risky debt and the value of the unhedged firm. (10 points) Answer: Yield on risky debt satisfies: 250 · (1.05) = 0.5 · 180 + 0.5 · 250 · (1 + x). Therefore, x = 0.38.
