Provisions for dismantling and restoration, disclosure of discount rate and sensitivity, policy, judgements

Swisscom Ltd – Annual report – 31 December 2021

Industry: telecoms

3.5 Provisions and contingent liabilities (extract 1)


Provisions for dismantling and restoration costs

The provisions are computed by reference to estimates of future anticipated dismantling costs and are discounted using an average interest rate of 0.91% (prior year: 0.58%). Adjustments as a result of reassessments in the amount of CHF -21 million were recognised under property, plant and equipment with no impact on the income statement in 2021. Of this amount, CHF -45 million resulted from the use of different interest rates, CHF 9 million from the adjustment of the cost index used to calculate dismantling costs and CHF 15 million from other effects. An increase of estimated costs by 10% would result in an increase of CHF 69 million in the amount of the provision. A delay of another ten years in the timing of the dismantling would lead to an increase of CHF 41 million in the provisions.

Significant judgements or estimates

The provisions for dismantling and restoration costs relate to the dismantling of telecommunications installations and transmitter stations as well as the restoration to its original state of land held by third-party owners. The level of the provisions is determined to a significant degree by the estimation of future dismantling and restoration costs, as well as the timing of dismantlement. The provisions and contingent liabilities for regulatory and antitrust proceedings relate to proceedings in connection with regulated access services provided by Swisscom and proceedings initiated by COMCO. The legal and accounting assessment of these proceedings is associated with significant uncertainties in estimation and scope for discretion with regard to the probability of occurrence and the amount of a possible cash outflow. The provisions recognised in this way constitute the best estimate of the liability. Possible liabilities whose occurrence as at the balance-sheet date cannot be assessed, or liabilities for which the level cannot be reliably estimated, are disclosed as contingent liabilities.

Accounting policies (extract)

Provisions are recognised whenever a legal or constructive obligation arises from past events, the outflow of resources to settle the liability is probable, and the amount of the liability can be estimated reliably. Provisions are discounted if the effect is material.

Provisions for dismantling and restoration costs

Swisscom is legally obligated to dismantle transmitter stations and telecommunications installations located on land belonging to third-parties following decommissioning, and to restore to its original state the property owned by third-parties in the locations where these installations are erected. The costs of dismantling are capitalised as part of the acquisition costs of the installations, and are amortised over their useful lives. The provisions are measured at the present value of the aggregate future costs, and are reported under non-current provisions. Whenever the provision is re-measured, the present value of the changes in the liability is either added to or deducted from the cost of the related capitalised item of property, plant and equipment. The amount deducted from the cost of the related asset may not exceed its carrying amount. Any excess is taken directly to income.
