Expertise · IFRS & Cost

IFRS tells you the number. We tell you why.

Financial accounting sets the reporting obligation. But the number you report, the cost of inventory, the segment profit, the performance measure, is only as sound as the cost allocation underneath it. We build that cost model, so applying IFRS rests on evidence rather than estimates.

Cost and Profitability Consulting · 25 years of TDABC · We are not your auditor: we are the cost model under the report

IAS 2

requires fixed overheads to be allocated to inventory on normal capacity. A wrong absorption rate distorts the balance sheet and cost of sales.

IFRS 18

effective 1 Jan 2027, brings management metrics inside the audited statements. They now have to be supported.

IFRS 8

requires a measure of profit per segment. It is only as good as the cost allocation beneath it.

01The thesis

The standard sets the obligation. The cost model sets the truth.

IFRS tells you that you must report inventory cost, segment profit and management measures consistently and comparably. It does not tell you how to attribute cost accurately. That is where most organisations fall back on inherited, rarely-questioned volume-based absorption rates.

When cost is spread by volume, complex products look cheap, demanding customers look profitable, and the number you report, while technically compliant, is wrong in substance. Time-Driven Activity-Based Costing closes that gap: it gives you a defensible cost allocation, traceable to the activity that caused it.

02The standards

Where cost allocation meets the standard.

IAS 2

Inventories and normal capacity

IAS 2 requires fixed production overheads to be allocated to inventory cost on normal capacity, with idle-capacity cost expensed. TDABC measures that capacity and attributes the cost precisely.

IFRS 18

Presentation and management measures

From 2027, Management Performance Measures enter the audited statements, reconciled to IFRS subtotals. A TDABC model makes those metrics traceable and defensible in front of the auditor.

IFRS 8

Operating segments

IFRS 8 requires a measure of profit per segment, as management sees it. TDABC shows which customers, products and channels within each segment create or destroy value.

IAS 36 / NRV

Impairment and net realisable value

Impairment tests by cash-generating unit and the net realisable value of inventory both depend on correctly attributed costs. A sound cost model supports both.

03How we help

We build the model. Your auditor signs off the report.

We do not replace your auditor or your finance team. We give them the cost foundation they need to apply the standards with confidence.

01

Model the cost with TDABC

Timed activities, cost pools and normal capacity, at product, customer and segment level. A base that stands up to scrutiny.

02

Map to the standard

We link the model output to what each standard requires: inventory cost for IAS 2, subtotals and measures for IFRS 18, segment profit for IFRS 8.

03

Hand you a model you own

Your team updates and reconciles it. Every number you report becomes traceable to the activity that drove it, and defensible in front of the board.

Scope note: Cost and Profitability Consulting is not an audit firm and does not issue IFRS compliance opinions. Our work is to build and implement the cost model that underpins the application of these standards. Responsibility for financial reporting and its audit remains with the organisation and its auditors.

04Frequently asked questions

Questions a Finance Director asks.

What does Cost and Profitability do in relation to IFRS?
We are not auditors and we do not issue compliance opinions. We build the cost model, using Time-Driven Activity-Based Costing, that makes applying standards such as IAS 2, IFRS 18 and IFRS 8 more robust and defensible. The standard sets the reporting obligation; the model explains and supports the number.
How does IAS 2 connect to activity-based costing?
IAS 2 requires fixed production overheads to be allocated to inventory cost based on normal capacity, with the cost of under-utilisation expensed in the period. TDABC gives you a defensible measure of normal capacity and a defensible cost allocation, instead of crude volume-based absorption rates that distort both inventory value and cost of sales.
Why is IFRS 18 relevant to our cost model?
IFRS 18, effective for periods beginning on or after 1 January 2027, replaces IAS 1 and brings Management Performance Measures inside the audited financial statements, reconciled to IFRS subtotals. The management metrics your leadership relies on now have to be supported. A TDABC model makes those metrics traceable to source and defensible in front of the auditor and the board.
Does IFRS 8 require us to disclose customer profitability?
Not at the individual customer level, but it does require a measure of profit or loss per operating segment, as reported to the chief operating decision maker. The quality of that measure depends entirely on the cost allocation underneath it. TDABC shows you which customers, products and channels within each segment create or destroy value, giving substance to what IFRS 8 asks you to report.
