Finance and Business Impact

What this module covers

Module 5 carries 10 questions, and it is where good candidates most often fail the exam. They revise hard on the engineering content, arrive at a module that feels foreign, and fall below 50 per cent on ten questions, which ends the attempt whatever their overall score. The material is not difficult. It is just unfamiliar, and a few ideas account for most of it.

Capital and operating expenditure

Capital expenditure creates, enhances or replaces an asset and brings benefit over more than one period. Examples are a new pumping station, an upgrade that adds capacity, or buying land. Operating expenditure keeps the asset running in its current state and is charged in the year it is incurred. A routine maintenance contract is the classic example. Renewal is normally capital; maintenance normally operating.

Depreciation, and what it is not

Depreciation spreads an asset's cost across the periods in which it is used. It is an accounting allocation, and three misunderstandings cost marks every sitting. It is not cash set aside to pay for replacement. It is not a measure of condition. And a fully depreciated asset does not have to be replaced, because many run well for years afterwards.

Appraisal methods

Know what each method measures and where it falls short:

• Payback period: the time taken to recover the initial outlay. Simple, but it ignores everything after the payback point and the timing of cash within it.
• Discounted payback: the same, using cash flows discounted to present value, so the payback point comes later.
• Net present value: the present value of inflows minus the present value of outflows. Positive means value is added at the chosen rate.
• Internal rate of return: the discount rate at which NPV would be zero. It is compared against the required return.
• Return on capital employed: operating profit as a share of the capital used to generate it.

Discounting reflects the time value of money: a pound today is worth more than a pound in ten years. It is a separate idea from inflation.

The financial statements

The balance sheet shows position at a date: what the organisation owns and owes. The profit and loss statement shows performance over a period: revenue, costs and profit. The cash flow statement shows money in and out over a period. Profit and cash are different things. A profitable organisation can still lack the cash for its renewal programme when the bills fall due.

Making the case

Whole-life cost is how options should be compared. A business case should state the problem and compare real options, including doing nothing, because that is the baseline everything else is measured against. Deferring spend moves cost rather than removing it, and it usually increases the total. Money already spent is a sunk cost and should not affect whether to continue. Optimism bias, the steady tendency to underestimate costs and overestimate benefits, is why benefits should be checked once the asset is in service.

Where marks are lost

• Believing depreciation is cash, or that full depreciation means an asset must be replaced
• Mixing up capital and operating expenditure
• Mixing up what the three financial statements show
• Confusing payback, NPV and IRR
• Letting sunk costs drive a decision about continuing
