Weights are 40% debt 60% equity. Now regarding the PV of the debt…
The answer above is incorrect because it mixes redemption and interest payments. This is actually pretty straight forward:
The redemption is discounted for 5 periods at 13.65%. The interest payments are discounted for 10 years at a discount rate of 6.825% (13.65/2). This gives me a PV of 8.1M .
I would argue that this is wrong, because the redemption is not paid semi-annually. Therefore the effective semi-annual interest rate is not just (i/yr)/2, but (i/yr)^0.5. In other words, you will have different results if you take the redemption of $10M and discount it with 13.65% over 5 years vs. 6.825% over 10 years.
