CHAPTER 11 – 5
6. We will use the tax shield approach to calculate the OCF for the best- and worst-case scenarios. For
the best-case scenario, the price and quantity increase by 10 percent, so we will multiply the base-
case numbers by 1.1, a 10 percent increase. The variable and fixed costs both decrease by 10 percent,
so we will multiply the base-case numbers by .9, a 10 percent decrease. Doing so, we get:
The best-case NPV is:
For the worst-case scenario, the price and quantity decrease by 10 percent, so we will multiply the
base-case numbers by .9, a 10 percent decrease. The variable and fixed costs both increase by 10
percent, so we will multiply the base-case numbers by 1.1, a 10 percent increase. Doing so, we get:
The worst-case NPV is:
7. The cash break-even equation is:
QC = FC/(P – v)
And the accounting break-even equation is:
QA = (FC + D)/(P – v)
Using these equations, we find the following cash and accounting break-even points:
a. QC = $8,100,000/($2,980 – 2,135) QA = ($8,100,000 + 3,100,000)/($2,980 – 2,135)
b. QC = $185,000/($46 – 41) QA = ($185,000 + 183,000)/($46 – 41)
c. QC = $2,770/($9 – 3) QA = ($2,770 + 1,050)/($9 – 3)
