Answer:
To determine which projects Ziege Systems should accept, we need to compare the projects' rates of return with the adjusted WACC based on their risk levels.
For high-risk projects, the adjusted WACC is 12.75% (10.75% + 2%), and for low-risk projects, the adjusted WACC is 8.75% (10.75% - 2%).
For projects A, B, E, and F, which are high-risk projects, we can calculate their adjusted net present values (NPVs) using the adjusted WACC of 12.75%:
- - Project A: NPV = -$4 million + ($4 million / (1 + 0.1275)^1) = -$3,518,519.58
- - Project B: NPV = -$5 million + ($5 million / (1 + 0.1475)^1) = -$4,319,651.17
- - Project E: NPV = -$6 million + ($6 million / (1 + 0.1325)^1) = -$5,266,343.57
- - Project F: NPV = -$5 million + ($5 million / (1 + 0.1325)^1) = -$4,578,004.12
For projects C, D, G, and H, which are low or average-risk projects, we can calculate their adjusted NPVs using the adjusted WACC of 8.75%:
- - Project C: NPV = -$3 million + ($3 million / (1 + 0.1025)^1) = $211,039.03
- - Project D: NPV = -$2 million + ($2 million / (1 + 0.1025)^1) = $851,739.13
- - Project G: NPV = -$6 million + ($6 million / (1 + 0.0825)^1) = $1,395,348.84
- - Project H: NPV = -$3 million + ($3 million / (1 + 0.1275)^1) = -$2,631,578.95
Based on these calculations, Ziege Systems should accept projects C, D, G, and H because they have positive adjusted NPVs. Projects A, B, E, and F should be rejected because they have negative adjusted NPVs.
If Ziege Systems can only invest a total of $13 million, it should select projects C, D, and H, which have a total required investment of $8 million and a total adjusted NPV of $431,200.16 ($211,039.03 + $851,739.13 - $2,631,578.95). Project G has a higher adjusted NPV, but it is more expensive than project H and would push the total investment over the budget constraint.
Therefore, the dollar size of Ziege Systems' capital budget would be $13 million.
