1.4Changes in accounting policies

In the 2025/26 financial year the Group adopted the following new IFRS Accounting Standards, interpretations and amendments to existing ones, without having a significant impact on the Groupʼs result and financial position:

  • Lack of Exchangeability – Amendments to IAS 21

The Group has assessed the expected impacts of the new and revised standards and interpretations that will be effective for the financial year starting 1 April 2026. These standards are not expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions. The Group is also assessing other new and revised standards which are not mandatory until after 2026.

IFRS 18 “Presentation and Disclosure in Financial Statements”: The new standard on presentation and disclosure in financial statements. The key new concepts introduced in IFRS 18 relate to the structure of the statement of profit or loss, required disclosures in the financial statements for certain profit or loss performance measures that are reported outside an entityʼs financial statements and enhanced principles on aggregation and disaggregation which apply to the primary financial statements and notes in general. The Group is still in the process of assessing the impact of the new accounting standard that will become effective from 1 April 2027, particularly with respect to the structure of the Groupʼs consolidated income statement, consolidated cash flow statement and the additional disclosures required.

1.3Significant accounting judgments and estimates

Preparation of financial statements in conformity with IFRS Accounting Standards requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. This includes estimates and assumptions in the ordinary course of business as well as non-recurring events such as the outcome of pending legal disputes. The estimates and assumptions are continuously evaluated and are based on experience and other factors, including expectations of future events that are believed to be reasonable. Actual results may differ from these estimates and assumptions.

The main estimates and assumptions with a significant risk of resulting in a material adjustment within the next financial year are described in the following notes:
