1 Changes in accounting principles

The consolidated interim financial statements were prepared in accordance with the accounting policies described in the 2022 consolidated financial statements and the amendments described below.

As of 1 January 2023, Swisscom adopted various amendments to the existing International Financial Reporting Standards (IFRS) and interpretations, none of which has a material impact on the results or the financial position of the Group. From 2023 Swisscom will now take into account other factors, such as market conditions and other entity-specific factors, in addition to contractually agreed prices, when determining the fair value for revenue and cost recognition of individual roaming contracts that contain minimum guarantees. The prior year’s comparatives have been restated accordingly. The change reduced revenue and direct costs for the first nine months of 2022 by CHF 46 million in each case (CHF 61 million each for the full year).
