ICAEW ACA FAR common mistakes
ICAEW ACA FAR · Understand the traps and how to avoid them.
In a consolidated statement of financial position, adding the subsidiary's share capital and retained earnings line-by-line to the parent's instead of eliminating the subsidiary's pre-acquisition equity against the cost of investment, leaving share capital overstated by the subsidiary's nominal amount.
Candidates learn 'line-by-line addition' as the core consolidation mechanic and apply it mechanically to every line, forgetting that share capital and pre-acquisition reserves are the investment the parent already paid for and must cancel out. The elimination entry is invisible in the individual statements, so there is nothing to remind them.
What to do instead
Before writing any numbers, draft the elimination in a working: Dr share capital (sub), Dr pre-acquisition retained earnings (sub), Dr goodwill, Cr cost of investment, Cr NCI. Then check that consolidated share capital equals the parent's share capital only, and that consolidated retained earnings equals parent's plus group share of post-acquisition reserves only. Build this reconciliation as a standing check every time.
Calculating non-controlling interest at the reporting date as simply the NCI percentage multiplied by the subsidiary's closing net assets, without adjusting for fair value uplifts at acquisition (e.g. an upward land revaluation) or for unrealised profit on intragroup trading.
The shorthand 'NCI % x net assets' works in the simplest textbook cases and candidates memorise it as a formula rather than a logic. Under full or partial goodwill methods the closing net assets must be the group's measure, not the subsidiary's own book figure.
What to do instead
Compute NCI from a structured schedule: subsidiary's book net assets at reporting date, plus acquisition-date fair value adjustments still outstanding (and their depreciation), less unrealised intragroup profit (PUP), then multiply by the NCI share. Reconcile opening NCI to closing NCI by adding NCI share of profit and deducting NCI share of dividends, and use that reconciliation as the cross-check.
Computing goodwill as consideration paid minus the subsidiary's book net assets, omitting the fair value uplift on identifiable net assets at acquisition, the fair value of previously held interests in a step acquisition, and contingent consideration measured at acquisition-date fair value.
The formula 'cost less net assets' is short, memorable, and correct only when book value equals fair value and the parent buys in one go for cash. Exam questions embed fair value adjustments and step acquisitions precisely to test whether candidates rebuild the full IFRS 3 measurement.
What to do instead
Use a four-line goodwill proforma every time: (1) consideration transferred at fair value, (2) plus fair value of any previously held interest, (3) less the group's share of fair-valued identifiable net assets, (4) with NCI measured either at fair value or proportionate share and stated explicitly. Annotate each line with the standard reference so omissions are visible.
Failing to eliminate intragroup sales and balances in full before applying the ownership percentage, and then applying the PUP adjustment to the whole group rather than only to the seller's profit element.
Candidates conflate two different eliminations: intragroup revenue, receivables and payables are eliminated 100% because the group cannot trade with itself, whereas unrealised profit is eliminated 100% from group profit but then shared between parent and NCI. Mixing the two produces a PUP adjustment scaled by the parent's holding, which is wrong.
What to do instead
Separate the two workings physically on the page. Working A: eliminate 100% of intragroup sales, purchases, receivables and payables. Working B: unrealised profit = intragroup selling price x margin x proportion still held in inventory, eliminated in full from consolidated profit, then allocate the NCI share of that adjustment in the NCI schedule. State the selling entity so the direction of the adjustment is unambiguous.
Preparing the consolidated statement of cash flows by adding parent and subsidiary cash flows and then treating the acquisition of the subsidiary as a single 'investment' outflow, without adjusting for the cash actually acquired and without eliminating intragroup dividends and loans.
The consolidation adjustments that make the income statement and balance sheet work are invisible in the cash flow statement, so candidates default to simple addition. The acquisition adjustment in particular requires knowing cash paid less cash acquired, which is a separate computation from the goodwill calculation.
What to do instead
Work through a checklist: eliminate intragroup dividends (they are internal transfers), eliminate intragroup loans and the related interest, remove the subsidiary's post-acquisition profit from operating cash flow only via the group workings rather than double counting, and show the acquisition as consideration paid in cash less cash and cash equivalents acquired, disclosed separately. Reconcile the movement in consolidated cash to the opening and closing group balance sheet figures.
Applying a new or revised accounting standard prospectively when it requires retrospective application (or vice versa), and failing to present the third balance sheet where a retrospective restatement materially affects the opening position.
Candidates memorise the substance of standards but skim the transitional provisions, which sit at the end of the standard and are rarely the focus of study notes. IAS 8's distinction between changes in accounting policy (retrospective) and changes in estimate (prospective) is often blurred under exam pressure.
What to do instead
For every standards question, write one line at the top: 'Transitional provision: retrospective or prospective?' and cite it. Then apply the IAS 8 mechanics: retrospective changes adjust opening retained earnings, restate comparatives, and require a third statement of financial position when the restatement materially affects the opening position. Changes in estimate affect only current and future periods.
Recognising revenue at the point of invoicing for a contract with distinct performance obligations, instead of allocating the transaction price to each obligation and recognising revenue as each is satisfied, including over-time recognition where control transfers continuously.
The five-step IFRS 15 model is easy to recite and hard to apply. Candidates default to the invoice date because it is the date on the document, and they under-recognise the need to identify separate performance obligations in bundled contracts and to adjust for variable consideration and significant financing components.
What to do instead
Force every revenue scenario through the five steps in writing: identify the contract, identify performance obligations, determine and allocate the transaction price (including variable consideration constrained to the amount highly probable not to reverse), recognise when each obligation is satisfied, and check contract asset versus receivable presentation. For construction and service contracts, compute percentage complete on a cost or input basis and show the contract asset or liability separately from trade receivables.
Treating a lease as a simple operating expense, or calculating the lease liability as the sum of undiscounted future payments, rather than discounting at the rate implicit in the lease (or the lessee's incremental borrowing rate) and separating the interest and depreciation charges.
Candidates carry over the old operating lease intuition and underweight the arithmetic of discounting. The liability is a present value, and the subsequent measurement requires splitting each payment between interest and capital, which is a schedule most candidates try to shortcut.
What to do instead
Build the lease liability as the present value of payments over the lease term including extension options reasonably certain to be exercised, using the implicit rate or incremental borrowing rate. Then prepare a full amortisation schedule: opening liability, interest at the discount rate, payment, closing liability. Separately depreciate the right-of-use asset over the shorter of useful life and lease term. Present the current and non-current portions of the liability separately.
In ratio analysis questions, computing ratios correctly but interpreting them without a comparator, and drawing conclusions from a single year's movement without decomposing it (e.g. calling a falling gross margin a pricing problem when it is a product mix or inventory write-down effect).
Candidates treat ratio questions as arithmetic tests and stop once the number is calculated. Interpretation requires a benchmark, a trend, and a decomposition into drivers, none of which are prompted explicitly by the question stem.
What to do instead
For every ratio, state the formula, the figure, the comparator (prior year, competitor, industry, or covenant) and then the driver decomposition. Use the DuPont breakdown for return on capital employed (margin x asset turnover), decompose margin changes into price, volume, mix and cost, and always close with a limitation of the analysis (e.g. accounting policy differences, one-off items, seasonal balance sheet dates).
Presenting an asset or liability at the wrong measurement basis because the classification test was skipped - for example, classifying a investment in a subsidiary as fair value through profit or loss in the parent's separate statements, or measuring a financial asset at amortised cost when it fails the solely-payments-of-principal-and-interest test.
Candidates jump to the measurement number because that is what the question seems to ask for, and the classification decision (business model plus cash flow characteristics, or control versus significant influence versus joint control) is treated as background reading rather than the step that determines every subsequent number.
What to do instead
Write the classification test explicitly before any measurement: for financial assets, state the business model and whether the contractual cash flows are solely payments of principal and interest, then derive the category; for investments in other entities, apply the control, joint control, significant influence sequence and state the resulting treatment in the separate and consolidated statements. Only then compute the carrying amount, and cross-check that the measurement basis is consistent with the classification you wrote.
