Explain the kinds of capital investment a firm makes and how it allocates capital
The idea
Capital investments fall into recognisable types: maintenance spending that keeps existing capacity running, expansion projects that add capacity, new-product investments with the widest range of outcomes, and regulatory or compliance spending that must happen regardless of return. The allocation process runs from idea generation through analysis and authorisation to post-audit, and the post-audit step is the one most often skipped. Without it, systematic optimism in forecasts is never detected, and the same biased assumptions are used on the next proposal.
A practice question
Which type of capital investment typically proceeds regardless of its calculated return?
- Expansion projectsWhy not: Discretionary by nature, and the category most rigorously tested against the cost of capital.
- Regulatory or compliance spending - correct
- New product developmentWhy not: The most uncertain category and the one most in need of scrutiny, not the one exempt from it.
Capital investment means spending on long-lasting assets such as buildings and equipment. Most projects are optional, so they are accepted only if the return beats the cost of capital. Compliance (regulatory) spending is different because the law requires it. For example, a factory that must fit emission filters to keep its operating licence will spend the money whatever the return. The only real question is which way of complying costs least. Rule: compulsory projects skip the usual go or no-go return test.
A harder one
Why is the post-audit step in capital allocation valuable even though the money is already spent?
- It allows the initial investment to be reversed if the results disappointWhy not: Most capital spending cannot be undone, which is precisely why the forecasts matter so much.
- It is required before the capital expenditure can be deducted for taxWhy not: Deductibility follows the tax rules on the asset, not an internal review.
- It reveals systematic forecasting bias so later proposals can be assessed more realistically - correct
A post-audit means comparing what a project actually delivered with what was forecast. The money is already spent and usually cannot be recovered, so the value lies in learning. If a review shows that one division's projects delivered only 70% of forecast sales three times running, later proposals from it can be adjusted down. Formula: Forecast error = (Actual - Forecast) / Forecast. People who know their forecasts will be checked also tend to make more honest ones. Rule: use past mistakes to improve future estimates.
The hardest tier
Why do new-product investments usually warrant more analytical scrutiny than maintenance spending of the same size?
- Because their cash flows are far more uncertain and the range of outcomes is wider - correct
- Because they are depreciated over a shorter life than maintenance assetsWhy not: Depreciation policy follows the asset and is not what makes the decision uncertain.
- Because maintenance spending is not treated as a capital investment at allWhy not: It very often is capitalised, and either way it is a real use of funds.
Maintenance spending keeps an existing business running, so its cash flows are already known. A new product depends on guesses about demand, pricing and how competitors will respond, so the possible outcomes are far wider. Scrutiny should follow uncertainty, not just size. For example, replacing a $10 million machine that already makes sales is far more predictable than launching a $10 million product nobody has yet bought. Rule: the more uncertain the cash flows, the more careful the analysis must be.
