IFRS 18 Explained Key Changes from IAS 1 for Businesses

IFRS 18: A New Era of Financial Statement Presentation

Financial reporting is entering a significant new phase with the introduction of IFRS 18 – Presentation and Disclosure in Financial Statements. Effective for annual reporting periods beginning on or after 1 January 2027, IFRS 18 replaces IAS 1 and introduces a more structured approach to presenting financial performance.

While IFRS 18 does not change how companies measure income, expenses, assets, or liabilities, it fundamentally changes how financial performance is presented and disclosed. The objective is to improve transparency, consistency, and comparability across industries, enabling investors and other stakeholders to make more informed decisions.

Organizations should begin assessing the impact well before the mandatory adoption date, as implementation extends beyond financial reporting and affects accounting systems, internal controls, reporting processes, and governance. Hallmark Auditors supports businesses with Outsourced Accounting Services in Dubai and IFRS-compliant financial reporting to simplify this transition.

The New Structure of the Income Statement

One of the most significant changes introduced by IFRS 18 is the standardized structure of the Statement of Profit or Loss. Income and expenses are classified into defined categories, creating greater consistency across financial statements while improving users’ ability to compare operating performance.

The statement generally includes:

  • Operating Category
  • Investing Category
  • Financing Category
  • Income Taxes
  • Discontinued Operations

The following mandatory subtotals must now be presented:

  • Operating Profit
  • Profit Before Financing and Income Taxes
  • Profit Before Tax
  • Profit for the Year

This structured presentation provides users with a clearer understanding of operational performance before financing and taxation effects are considered.

Greater Focus on Operating Performance

Operating profit becomes one of the most important mandatory subtotals under IFRS 18. Previously, companies had considerable flexibility in defining operating results, resulting in inconsistent reporting practices across industries.

The new requirements establish a more comparable measure of operating performance by clearly separating:

  • Core operating activities
  • Investing activities
  • Financing activities

This provides investors with a more consistent basis for evaluating business performance and forecasting future cash flows.

Management Performance Measures (MPMs)

Many organizations communicate alternative performance measures such as:

  • EBITDA
  • Adjusted Operating Profit
  • Adjusted Earnings

Under IAS 1, these measures were not subject to specific disclosure requirements.

Where an entity presents MPMs in public communications, it must disclose:

• The purpose of each measure

• How the measure is calculated

• Reconciliation to the nearest IFRS subtotal

• Tax and non-controlling interest effects where applicable

• Changes in methodology from previous reporting periods

These requirements enhance transparency while reducing inconsistency in the presentation of non-GAAP performance measures.

Improved Aggregation and Disaggregation

IFRS 18 introduces clearer guidance on how information should be grouped within financial statements. Entities are expected to:

  • Aggregate items with similar characteristics.
  • Disaggregate items with different characteristics.
  • Avoid obscuring material information.
  • Present information at an appropriate level of detail.

The objective is to ensure financial statements communicate information clearly without excessive summarization or unnecessary complexity.

Enhanced Expense Disclosures

Entities may continue presenting operating expenses:

• By nature

• By function

• Using an appropriate combination of both

However, IFRS 18 requires additional disclosures for key expense categories, including:

  • Depreciation
  • Amortisation
  • Employee benefits
  • Impairment losses and reversals
  • Inventory write-downs and reversals

These disclosures provide users with greater insight into cost structures and profitability drivers.

Practical Implementation Challenges

Although IFRS 18 does not change accounting recognition or measurement, implementation will require significant operational changes across organizations. Key challenges include:

1. Chart of Accounts and ERP Systems

Existing chart of accounts and ERP systems may require redesign to capture the new presentation categories and reporting requirements.

2. Comparative Financial Information

Entities must restate comparative information when adopting IFRS 18, making historical data mapping an important implementation exercise.

3. Governance of Management Performance Measures

Organizations should establish formal governance over MPMs to ensure consistency, documentation, approval processes, and compliance with disclosure requirements.

4. Consolidation and Group Reporting

Group reporting packages and consolidation systems may require updates to accommodate the revised presentation requirements.

5. Internal Controls and Audit Readiness

Internal controls over financial reporting should be reviewed to ensure accurate classification, disclosure, and reporting under the new standard.

6. Materiality and Disclosure Processes

Finance teams will need to reassess disclosure frameworks, aggregation policies, and presentation methodologies.

7. Budgeting and Management Reporting

Internal management reports should align with the new reporting structure to maintain consistency between internal and external reporting.

8. Board and Stakeholder Communication

Boards, investors, lenders, and other stakeholders should be informed of the presentation changes to avoid misinterpretation of financial performance trends.

9. Treasury Considerations

The revised classification of financing activities may affect treasury reporting, financing metrics, and financial analysis.

If your organization cannot confidently answer these questions, now is the ideal time to conduct an IFRS 18 readiness assessment with experienced accounting and audit company before the mandatory implementation deadline.

Questions CFOs Should Be Asking Today

Preparing early will help organizations achieve a smoother transition. Management should consider the following questions:

  • Have we completed an IFRS 18 impact assessment?
  • Have we identified all Management Performance Measures?
  • Is our ERP system capable of supporting the new reporting requirements?
  • Can we generate comparative financial information?
  • Have our accounting policies been updated?
  • Are external auditors aligned with our implementation approach?
  • Have finance teams received appropriate training?
  • Have general ledger accounts been mapped to the new reporting categories?
  • Can we clearly identify Operating Profit under IFRS 18?
  • Has the Board been informed about the reporting changes?

Conclusion

IFRS 18 represents one of the most significant changes to financial statement presentation in recent years. Although it does not alter the recognition or measurement principles of IFRS Accounting Standards, it introduces a more consistent framework for presenting financial performance, enhancing transparency, comparability, and decision-usefulness.

Successful implementation will require more than updating financial statement formats. Organizations should evaluate accounting policies, reporting systems, ERP configurations, internal controls, governance frameworks, and stakeholder communications well in advance of the effective date.

Companies that begin preparing early will be better positioned to manage the transition efficiently while delivering higher-quality financial reporting that meets the expectations of investors, regulators, and other stakeholders.
