the old asset. The operating cash inflows are the difference between the operating
cash inflows from the new asset and those from the old asset. The terminal cash
flow is the difference between the after-tax cash flows expected upon termination
of the new and the old assets. These relationships are shown in Figure 8.4.
Actually, all capital budgeting decisions can be viewed as replacement deci-
sions. Expansion decisions are merely replacement decisions in which all cash
flows from the old asset are zero. In light of this fact, this chapter focuses primar-
ily on replacement decisions.
Sunk Costs and Opportunity Costs
When estimating the relevant cash flows associated with a proposed capital
expenditure, the firm must recognize any sunk costsand opportunity costs.These
costs are easy to mishandle or ignore, particularly when determining a project’s
incremental cash flows. Sunk costsare cash outlays that have already been made
(past outlays) and therefore have no effect on the cash flows relevant to the cur-
rent decision. As a result, sunk costs should not be included in a project’s incre-
mental cash flows.
Opportunity costsare cash flows that could be realized from the best alterna-
tive use of an owned asset. They therefore represent cash flows that will not be
realizedas a result of employing that asset in the proposed project. Because of
this, any opportunity costs should be included as cash outflows when one is
determining a project’s incremental cash flows.
EXAMPLE Jankow Equipment is considering renewing its drill press X12, which it purchased
3 years earlier for $237,000, by retrofitting it with the computerized control sys-
tem from an obsolete piece of equipment it owns. The obsolete equipment could
be sold today for a high bid of $42,000, but without its computerized control sys-
tem, it would be worth nothing. Jankow is in the process of estimating the labor
