Define the term ‘mutually exclusive projects’ and provide a simple example. Outline and justify the basic net present value rule applicable to them. How should this rule be modified when such projects have unequal lives? Two projects are said to be mutually exclusive if the selection of one project will automatically preclude the other project from being selected. This can be generalised to an n-project case. If a company owns land on which it can build either a factory or a warehouse, these two projects are said to be mutually exclusive because if a decision is made to build the factory, it is then impossible for the company to build the warehouse. The NPV rule for mutually exclusive projects with equal lives is to choose the project that gives the largest positive NPV. By choosing the project with the largest positive NPV, the company’s market value is maximised.

Compare machines over a life of 10 years. Assume zero scrap value in each case. Continue to operate old machine: Net cash flow = $10 000 – $7 000 = $3 000 per year 1  1  (1.10)10 NPV = $3 000   0.10   = $18 434 Purchase new machine now: Cost = $16 000 Disposal value of old machine = $1 000 Net cash flow = $11 000 – $5 000 = $6000 NPV
1  1  (1.10)10 = –$16 000 + $1 000 + $6 000   0.10   = $21 867      

As the NPV of purchasing the new machine exceeds the NPV of continuing to operate the old machine, the new machine should be purchased now. 2. The aim is to minimise the NPV of cash outflows.
