When is EAC analysis appropriate for comparing two or more projects? Why is this
method used? Are there any implicit assumptions required by this method that you find
The EAC approach is appropriate when comparing mutually exclusive projects with
different lives that will be replaced when they wear out. This type of analysis is
necessary so that the projects have a common life span over which they can be
compared; in effect, each project is assumed to exist over an infinite horizon of N-year
repeating projects. Assuming that this type of analysis is valid implies that the project
cash flows remain the same forever, thus ignoring the possible effects of, among other
things: (1) inflation, (2) changing economic conditions, (3) the increasing unreliability of
cash flow estimates that occur far into the future, and (4) the possible effects of future
technology improvement that could alter the project cash flows.
The Army has requested a bid for multiple use digitizing devices (MUDDs).

estimated that labor and materials costs will be $10,000 per unit.

The project will require $50,000 in fixed assets with
expected salvage of $10,000 at the end of the project (depreciate straight-line to salvage
value) and an initial $10,000 increase in NWC.
Your marginal tax rate = 34% and the

What is your minimum bid?
NPV = 0 = -60,000 + OCF(PVIFA
) + 20,000(PVIF
NPV = 0 = -60,000 + (NI + Dep)(2.2832) + 20,000(0.6575)
NPV = 0 = -60,000 + [(S – VC – FC - Dep)(1 – T) + Dep](2.2832) + 13,150.32
46,849.68 = [(4P – 4(10,000) – 12,000 – 13,333.33)(1 - .34) + 13,333.33](2.2832)
20,519.31 = (4P – 65,333.33)(0.66) + 13,333.33
7,185.98 = (4P – 65,333.33)(0.66)
