General disclosures
Reporting is divided into the segments Switzerland, Italy and Others. The Switzerland and Italy segments are engaged in largely identical business activities, differing only in their regional scope. Residential customers are offered telecommunications services such as mobile communication, fixed-line telephony, broadband and TV. Business customers receive IT solutions in addition to telecommunications services, covering the entire spectrum of business ICT infrastructure from individual products to end-to-end solutions. In addition, the network infrastructure is made available to other telecommunications providers as wholesale services. Each segment includes its respective national telecommunications network and IT infrastructure. Group-wide functions are reported within the Switzerland segment.
Segment expense encompasses the direct costs, personnel expense and other indirect costs. In the segment reporting, lease expenses of CHF 1,199 million (prior year: CHF 1,223 million) are allocated to direct costs (current year: CHF 641 million; prior year CHF 656 million) and other indirect costs (current year: CHF 558 million; prior year: CHF 567 million). Pension cost includes ordinary employer contributions. The difference between the ordinary employer contributions and the pension cost as provided for under IAS 19 is reported in the elimination column. The elimination column in the segment result, which totals CHF –40 million (prior year: CHF –48 million), includes expense of CHF 9 million (prior year: expense CHF 12 million) as a pension cost reconciliation item in accordance with IAS 19.

In general, IRUs are paid in full at the beginning of their use and are classified as leases under IFRS 16. From an economic point of view, IRU acquisitions will be considered as capital expenditure in the segment information.
