Q9–7. Why must incremental after-tax cash flows rather than total cash flows be evaluated in pro-
ject analysis?
A9-7. Incremental cash flows matter because the project evaluator is looking at what will change
Q9–8. Differentiate between sunk costs and opportunity costs. Which of these costs should be
included in incremental cash flows, and which should be excluded?
A9-8. Sunk costs should not be included in a cash flow analysis. These are costs that have already
been paid. Accepting or rejecting the project will not impact these costs. These are not in-
Q9–9. Why is it important to consider cannibalization in situations where a company is consider-
ing adding substitute products to its product line?
A9-9. Cannibalization is the “substitution effect” that frequently occurs when a firm introduces a
new product. Typically, some of the new product’s sales will come at the expense of the
Q9-10. Before entering graduate school, a student estimated the value of earning an MBA at
$300,000. Based on that analysis, the student decided to go back to school. After complet-
ing the first year, the student ran the NPV calculations again. How would you expect the
NPV to look after the student has completed one year of the program? Specifically, what
portion of the analysis must be different than it was the year before?
Q9-11. Punxsutawney Taxidermy Inc. (PTI) operates a chain of taxidermy shops across the Mid-
west, with a handful of locations in the South. A rival firm, Heads Up Corp., has a few
Midwestern locations, but most of its shops are located in the South. PTI and Heads Up
decide to consolidate their operations by trading ownership of a few locations. PTI will ac-
quire four Heads Up locations in the Midwest, and in exchange will relinquish control of
its Southern locations. No cash changes hands up front. Does this mean that an analyst
working for either company can evaluate the merits of this deal by assuming that the pro-
ject has no initial cash outlay? Explain.
A9-11. There are two ways to approach this problem. First, each company could estimate the cash
value of the stores that it is giving up. This is the cash price that the firm might obtain from
another buyer, and therefore represents the opportunity cost of this deal. This could be
