The following table presents FM's WACC using market values (where possible):

Difficulty: 2 Medium

The IRR of the investment is 15/100 = 15%. FM's WACC of 11.27% is shown in the table below. The NPV of the investment at the WACC = -100 + 15/.1127 = $33.1 million.

Difficulty: 1 Easy

R_e = 0.028 + 1.34 (0.112 - 0.028) = 0.14056; R_p = (0.07 ´ $100)/$53 = 0.13208
Market values of: debt = 80,000*$1,000 = $80.00M; preferred = 750,000*$53 = $39.75M; and common = 2.5M * $42 = $105.00M. These sum to $224.75M. Thus, the WACC = ($105M/$224.75M) (0.14056) + ($39.75M/$224.75M) (0.13208) + ($80M/$224.75M) (0.0675) (1 - 0.38) = 10.39 percent.

26. Explain the difference between systematic and unsystematic risk, and why one of these types of risks is rewarded with a risk premium while the other type is not.

Unsystematic, or diversifiable, risk affects a limited number of securities and can be eliminated by investing in securities from various industries and geographic regions. Unsystematic risk is not rewarded because it can be eliminated by investors. Systematic risk is risk that affects most, or all, securities and cannot be diversified away. Since systematic risk cannot be eliminated by investors it is rewarded with a risk premium. Systematic risk is measured by beta.

Difficulty: 2 Medium

If the investment is above the company's average risk, the company's cost of capital is not an appropriate benchmark. Equivalently, you might argue that the high risk of the investment places it below the security market line. Such investments destroy value because they promise returns that, while greater than the company's WACC, are still below those available on similar-risk investments available. Other possible arguments include: the investment is not consistent with the strategic plan; and, the cash flow estimates are too optimistic.

Difficulty: 2 Medium

The equation for beta in chapter 8 shows that the nondiversifiable risk of an asset is the product of its standard deviation of returns and the correlation of those returns with those on a well-diversified portfolio. Wildcat Oil Drilling may have a high standard deviation of returns, but if those returns are poorly correlated with those on a well-diversified portfolio, as is likely the case, nondiversifiable risk may be low.

Difficulty: 2 Medium

These investments have the same expected outcome but different dispersions of possible outcomes. Risk-averse investors will prefer investment B because it has the same return as A but at lower risk.

Difficulty: 2 Medium

30. What is the present value of a cash flow stream of $10,000 per year annually for 11 years that then grows at 2 percent per year forever? Assume the appropriate discount rate is 12 percent.

Divide the cash flows into two periods: An 11-year annuity of $10,000, and a growing perpetuity beginning in the 11^th year. The value of the 11-year annuity is
$59,376.99. The value of the growing perpetuity (using the formula provided in the chapter for a growing dividend into perpetuity) at time 11 is $10,000(1 + .02)/(.12-.02) = $102,000. Its value at time zero is $102,000/(1.12)¹¹ = $29,322.56. Adding these present values, $29,322.56 + $59,376.99 = $88,699.55.
