The standard changes more than layout. It defines operating profit for the first time, reshapes the cash flow statement and puts management’s own performance measures under audit-grade scrutiny. For a board, that touches earnings presentations, loan covenants and shareholder disclosures. This article explains each pressure point and gives CFOs a seven-step framework for automating how income and expenses are classified.
Quick answer: IFRS 18 replaces IAS 1. It requires every income and expense item to sit in one of five categories (operating, investing, financing, income taxes, discontinued operations), adds two mandatory subtotals (operating profit and profit before financing and income taxes) and requires disclosure of management-defined performance measures. It is effective from 1 January 2027, with earlier application permitted.
What actually changes in the income statement
The practical differences look like this.
Area | Under IAS 1 | Under IFRS 18 |
|---|---|---|
Operating profit | No standard definition. Companies chose their own. | Mandatory, defined subtotal. |
Categories | None required in profit or loss. | Five: operating, investing, financing, income taxes, discontinued operations. |
Company-defined measures such as adjusted EBITDA | Mostly outside the financial statements. | Qualifying measures disclosed in a note, reconciled to an IFRS subtotal. |
Indirect cash flow starting point | Varied: profit, profit before tax, or operating profit. | Operating profit. |
Interest and dividend cash flows | Accounting policy choice. | Choice removed for most entities. |
Why this reaches the boardroom: three pressure points
1. Earnings presentations
2. Debt covenants
- How the key terms are defined. Look at “Operating Profit”, “EBITDA”, “Consolidated Net Income” and “Accounting Principles”.
- Whether accounting standards are fixed at signing. Some agreements freeze them at the signing date. Others follow the standards as they change.
- What the amendment and notification clauses require. Some facilities oblige the borrower to tell the lender when accounting changes affect the covenant calculation.
3. Shareholder disclosures and the tax trail
A seven-step framework to automate IFRS 18 categorisation
Step 1: Build an inventory of every published performance measure
Step 2: Confirm whether any specified main business activity applies
Step 3: Write the classification rulebook
- Operating: the default for everything not captured elsewhere.
- Investing: returns from assets that generate income largely independently of the entity’s other resources, such as associates, joint ventures, investment property and cash and cash equivalents.
- Financing: income and expenses from liabilities that raise finance, plus interest on other liabilities.
- Income taxes and discontinued operations: as defined in the relevant standards.
Step 4: Add an IFRS 18 tag to the chart of accounts
Do not renumber accounts. Add a category attribute or dimension to each general ledger account and cost centre in your ERP. That one field drives everything downstream and lets you produce both the old and new formats from the same ledger.
Step 5: Automate the rules and route exceptions to people
Step 6: Build the bridge for every performance measure
Step 7: Run a shadow close through 2026, then test the controls
Timing | Milestone |
|---|---|
Now to December 2026 | Inventory measures, write the rulebook, tag the chart of accounts, review covenants |
Quarterly through 2026 | Shadow close in both formats, report differences to the audit committee |
Early 2027 | Agree comparative restatement and disclosure drafts with the auditor |
First 2027 interim period | First external reporting under IFRS 18 |
A worked illustration: same ledger, different operating profit
AED ‘000 | Category | Amount |
|---|---|---|
Revenue | Operating | 100,000 |
Cost of sales | Operating | (58,000) |
Selling, admin and other expenses | Operating | (27,000) |
Operating profit | Mandatory subtotal | 15,000 |
Share of profit of associate | Investing | 2,000 |
Interest income on bank deposits | Investing | 1,000 |
Profit before financing and income taxes | Mandatory subtotal | 18,000 |
Interest expense on bank borrowings | Financing | (4,000) |
Profit before income tax | Additional subtotal | 14,000 |
Income tax expense | Income taxes | (1,500) |
Profit for the year | 12,500 |
Mistakes to avoid
- Treating it as a relabelling exercise. Classification needs judgement and documentation.
- Ignoring the cash flow statement. The starting point and the interest and dividend rules both change.
- Leaving covenants untouched. Check the definitions now, not at the first compliance date.
- Running two versions of operating profit. If the board pack, the deck and the audited accounts disagree, expect questions from every direction.
- Starting in 2027. The comparatives, the interim reports and the lender conversations all begin earlier.
