ICAB PL Financial Management · Understand the traps and how to avoid them.

Mistake 1

Computing a project's NPV using accounting profit figures (earnings after depreciation and tax) instead of incremental free cash flows, so depreciation is deducted as if it were a cash outflow.

Candidates carry over the profit-and-loss mindset from earlier accounting papers and treat the income statement as the source of cash; depreciation is the only non-cash item most recall, so it gets subtracted rather than added back as a tax shield.

What to do instead

Build every appraisal from a cash-flow table: initial outlay, incremental operating cash flow = (revenue − cash costs)(1 − t) + depreciation × t, working-capital changes, and terminal salvage net of tax. Reconcile once to accounting profit to prove the difference is only depreciation and non-cash items, then never use profit again.

Mistake 2

Discounting a project's cash flows at the company's post-tax weighted average cost of capital regardless of the project's risk, or using the WACC when the project's gearing differs materially from the firm's target.

The WACC is the single discount rate taught and memorised, and candidates conflate 'cost of capital' with 'the firm's cost of capital'; they also forget that a subsidised or project-specific financing package changes the relevant rate.

What to do instead

Before discounting, state the project's risk class and financing assumption. Use a risk-adjusted rate for diversifying projects, an adjusted WACC for a different capital structure, and APV (base-case NPV plus financing side effects) when subsidised loans or issue costs are present. Show the rate choice explicitly in the answer.

Mistake 3

Mixing book values and market values in the WACC - for example weighting equity at balance-sheet net assets and debt at face value - and using the coupon rate as the cost of debt.

Published accounts are the most familiar data source, and candidates assume the interest rate printed on a loan or bond is its cost; they also forget that interest is tax-deductible.

What to do instead

Weight by market values (or target weights if given), take the cost of equity from CAPM or the dividend growth model, and take the cost of debt as the redemption yield (or coupon × (1 − t) only when debt is irredeemable or trading near par). State the tax rate and the ex-interest price used.

Mistake 4

Valuing a business or share by applying a P/E multiple to the wrong earnings figure - using historical earnings when a maintainable or forecast figure is required, or applying an unadjusted sector multiple to a company with different growth, gearing or accounting policies.

The P/E method looks arithmetically trivial, so candidates rush the numerator and ignore that the multiple embeds growth and risk assumptions that must be justified.

What to do instead

State which earnings basis is used and why (maintainable, adjusted for non-recurring items, after tax and after preference dividends), justify the multiple by reference to comparables' growth and risk, and cross-check with a DCF or dividend valuation. If the question gives both, present a range and explain the difference.

Mistake 5

Calculating the cost of equity with the dividend growth model but estimating growth by averaging historic dividend increases over an arbitrary period, or ignoring that retained earnings must earn the shareholders' required return.

The growth rate is the least mechanical input, so candidates grab the simplest historic average without checking whether it is sustainable or consistent with the retention ratio.

What to do instead

Use g = b × r (retention ratio × return on reinvested funds) as the primary estimate, cross-check against historic growth, and sanity-check against nominal GDP growth. Where growth exceeds the long-run rate, switch to a two-stage or H-model calculation rather than forcing a perpetual constant rate.

Mistake 6

Ignoring working capital in cash-flow forecasts and in the evaluation of credit or discount policy - treating sales growth as cash-neutral and comparing discount schemes on profit margin rather than on the change in financing cost and bad debts.

Working capital sits between the income statement and the cash flow statement, and candidates default to the profit effect because it is easier to compute; the time value of the receivables balance is then omitted entirely.

What to do instead

For every policy change, compute the incremental contribution from extra sales, the incremental investment in receivables (using the contribution margin, not the selling price, for the cost of carrying debtors), the change in bad debts and administration cost, and the financing cost at the opportunity cost of funds. Present the net annual benefit and, where relevant, its present value.

Mistake 7

Producing a capital investment appraisal with no discussion of qualitative factors, sensitivity, or the treatment of risk - answering a 25-mark question with a single NPV number and no recommendation.

Candidates treat the calculation as the whole answer and run out of time; they also lack a template for structuring discussion, so they repeat the numbers in prose instead of interpreting them.

What to do instead

Reserve roughly a quarter of the marks' worth of time for interpretation. Quantify sensitivity (the percentage change in a key variable that makes NPV zero), state the assumptions behind the forecast, list non-financial factors (strategic fit, regulation, staff capability), and finish with a clear accept/reject/investigate recommendation tied to the numbers.

Mistake 8

Confusing the objective of financial management with profit or revenue maximisation, and then failing to apply shareholder wealth maximisation consistently in dividend, financing and investment decisions.

Profit is the metric candidates have been rewarded for computing throughout their studies, and the exam's discussion questions reward a stated objective that is then contradicted by the recommendation given.

What to do instead

Open every discursive answer by stating the objective (maximising present value of shareholders' future returns, subject to risk and stakeholder constraints). Then test each option against it - for example, a dividend cut is justified only if the retained funds earn above the cost of equity.

Mistake 9

Applying Modigliani–Miller conclusions without stating the assumptions - claiming debt always lowers WACC in a world with taxes but ignoring financial distress, agency and signalling costs, and mis-stating the geared and ungeared beta formulae.

The MM propositions are memorised as slogans rather than derived, so the tax shield is applied mechanically and the relevering formula is recalled with the tax term in the wrong place.

What to do instead

Write the assumption list first (perfect capital markets, no distress costs, fixed perpetuity cash flows, debt risk-free in the basic case), then derive the result. For betas, use the standard relevering relationship with the tax term applied to the debt-equity ratio, and always add a paragraph on the trade-off between tax shield and distress costs for the realistic conclusion.

Mistake 10

Presenting calculations with no workings, unlabelled units, and rounded intermediate figures - so a single arithmetic slip loses all the method marks, and the marker cannot award follow-through credit.

Time pressure encourages candidates to jump to the final figure, and spreadsheet habits of carrying full precision are abandoned under exam conditions without a compensating discipline.

What to do instead

Adopt a fixed layout: state the formula, substitute the inputs with units, carry four significant figures through the workings, and round only the final answer. Label every column and state the currency and whether figures are in thousands. Where a result feeds a later part, box it so follow-through marks are visible.
