ACCT30002 Chap.3 Financial Performance Metrics
Financial Performance Metrics
Financial measures provide information and influence behaviour. This chapter calculates ROI, residual income and DuPont drivers, then explains why ROI can induce underinvestment when a project earns above the required return but below a division's historical ROI. It also treats EVA, denominator choices, short-termism and goal congruence as design issues rather than assuming a formula is neutral.
ROI equals operating profit divided by the investment base, while residual income subtracts a capital charge from operating profit. The contrast matters when a project earns more than the required return but less than the division's existing average ROI. The project creates value and adds residual income, yet an ROI-evaluated manager can rationally reject it to protect the reported percentage.
DuPont analysis decomposes ROI into profit margin and asset turnover so the reader can locate the operating driver behind the result. That diagnosis still needs context: margin may rise through genuine efficiency or deferred maintenance, and turnover may improve through better scheduling or by selling assets needed for resilience. Measurement definitions change behaviour as well.
Gross versus net assets, average versus closing balances, centrally controlled allocations and asset age can alter comparisons without any change in operating quality. EVA preserves the capital-charge logic while adding accounting adjustments that require judgment.
A strong response therefore calculates accurately, states whose decision rule is being applied, checks the denominator and pairs the financial signal with strategic and nonfinancial evidence.

ROI versus residual income
- 1Existing ROI is 18% and project ROI is 15%.
- 1Combined ROI is $2.1m divided by $12m, or 17.5%.
- 2Project residual income is $0.3m minus 12% of $2m, or $60,000.
- 2Accept because the project earns above the required return and raises residual income.
Key terms
- Return on investment
- Operating profit divided by the investment base.
- Residual income
- Operating profit less the required capital charge.
- Underinvestment
- Rejecting a value-creating project because it lowers an evaluated average return.
Financial Performance Metrics FAQ
Why can ROI cause underinvestment?
A manager may protect an existing high average ROI by rejecting a project with a lower project ROI, even when the project exceeds the organisation's required return. Residual income evaluates the incremental capital charge and therefore supports value-creating acceptance.
How does the DuPont formula help?
It decomposes ROI into profit margin and asset turnover. That shows whether return comes from profit per sales dollar or sales generated per asset dollar, helping management investigate operating drivers instead of treating the ratio as a verdict.
Is residual income always better?
No. It is an absolute measure that tends to be larger for larger units and depends on the chosen asset base and required return. Use consistent definitions and pair it with strategic and nonfinancial evidence.
Why do asset definitions change ROI?
ROI uses the investment base as its denominator, so gross versus net assets, average versus closing balances and treatment of leases or central assets can change the reported percentage. Asset age can also favour older units. Define the base consistently, disclose major timing effects and pair the comparison with operating and strategic evidence before judging management.
Exam move
Calculate ROI, project ROI, combined ROI and residual income on the same page. Practise explaining the conflict in one sentence. Then vary asset definitions and identify how a manager could improve the reported measure without creating value. Use a four-line routine: write the formula, substitute labelled values, compute the result and interpret the behavioural consequence. Keep percentages and dollar measures separate.
For an investment case, compare the project return with both the required return and the existing divisional ROI before recommending acceptance. Recompute residual income to show whether total value increases. For DuPont practice, create two divisions with the same ROI but different margin and turnover, then name the different operating risks each faces.
Add one measurement variation at a time, such as using closing assets, excluding a lease or changing the capital charge, and explain how the reported result moves. End with a counterfactual: what action would a rational manager take to improve this measure, and does that action support organisational value?
This final question turns arithmetic into performance-management analysis and exposes underinvestment, deferral or denominator management. Build a small error log for sign, unit and denominator mistakes. When an answer is wrong, recompute it without looking at the prior working and explain the source of the difference.
Create a comparison table showing ROI's relative comparability and residual income's alignment with the capital charge, including the size bias of an absolute measure. Rehearse a governance paragraph that defines profit, assets, averaging, allocations and the required return before evaluation begins.
In the final revision session, alternate numeric cases with short behavioural cases so formula recognition cannot substitute for choosing the correct performance issue.
