1. Accounting principles
General
The financial statements for Swissgrid Ltd, Aarau, have been prepared in accordance with the Swiss Law on Accounting and Financial Reporting (Title 32 of the Swiss Code of Obligations). The valuation principles applied are described below.
Conversion of foreign currency items
The accounting records are maintained in the local currency (Swiss francs, CHF). All short-term monetary assets and liabilities recognised in foreign currencies are converted at the exchange rate as of the balance sheet date. Transactions in foreign currencies are converted at the exchange rate on the day the transaction took place. Foreign exchange gains and losses resulting from transactions in foreign currencies are recognised in the income statement and are presented in the same item as the underlying transaction.
Cash flow statement
Cash and cash equivalents form the basis for the presentation of the cash flow statement. The cash flow from operating activities is calculated using the indirect method.
Revenue recognition
Revenue is recognised in the income statement upon performance of Swissgrid’s obligations. For activities regulated under the Federal Electricity Supply Act (StromVG), the measurement of performance is based mainly on energy volumes directly metered on the transmission grid or reported from downstream grid levels. For certain revenue and procurement items, initial billing values are available six weeks after delivery at the earliest, thereby rendering accruals based on historical and statistical data, as well as on estimates necessary for the revenue recognition of these items.
Activities according to StromVG
Volume- and tariff-related timing differences (surpluses and deficits)
According to Art.14 of the Electricity Supply Act (StromVG), grid utilisation costs must be allocated to users on a user-pays basis. The tariffs for a financial year are determined based on planned costs. Due to price and volume deviations, actual expenses and income vary from the tariff calculation on both the revenue and procurement side. This results in surpluses or deficits, i.e. the tariff revenues from a financial year are higher or lower than the actual expenses incurred during the same period. These volume- and tariff-related timing differences are transferred to the balance sheet and taken into account in cost and revenue calculations for future tariff periods. The expected reduction in volume- and tariff-related timing differences within twelve months of the balance sheet date is recognised as short-term surpluses or deficits in the balance sheet.
EBIT regulated under StromVG
Earnings before interest and taxes (EBIT) from activities related to the Federal Electricity Supply Act (StromVG) are defined in Article 13 of the Electricity Supply Ordinance (StromVV) and are equivalent to the interest applied to the assets required to operate the transmission system with the weighted average cost of capital rate (WACC) for the current year under review (= WACCt+0) and the interest applied to the volume and tariff-related timing differences with the weighted average cost of capital rate of WACCt+2 plus income taxes.
Invested operating assets consist of net current assets calculated on a monthly basis as well as the property, plant and equipment and intangible assets as at the end of the financial year. The weighted average cost of capital rate (WACC) is based on the current international practice of the WACC capital cost concept with reference to the Capital Asset Pricing Model (CAPM). Besides considering the findings of financial market theory, the regulatory framework conditions in Switzerland and the current situation in the money and capital market are also taken into account. The official weighted average cost of capital rates for 2021 (WACCt+0) and 2023 (WACCt+2) based on this method of calculation are unchanged from the 3.83% used in the previous year.
ElCom has the right to verify ex post the chargeability of Swissgrid’s operating and capital costs for tariff-setting purposes. In case of an ex post cost adjustment, an appeal can be lodged with the Federal Administrative Court with the possibility of appeal to the Federal Supreme Court. A cost adjustment impacting Swissgrid’s operating result is applied whenever no appeal is lodged, or whenever an appeal’s prospects for success are judged to be less than 50% on the basis of a reappraisal, or whenever a legally binding ruling is issued.
Property, plant and equipment
Property, plant and equipment are recognised at the cost of acquisition or production less accumulated amortisation and any impairment losses. Significant spare parts which are likely to be used for a longer period and whose use only takes place in connection with a non-current asset item are recognised in non-current assets and depreciated over the remaining useful life of the relevant asset. Depreciation/amortisation is calculated using the straight-line method on the basis of the estimated useful technical and economic service life.
The service life is determined as follows:
– Lines: 15 to 60 years
– Substations: 10 to 35 years
– Buildings and expansions: 5 to 50 years
– Other property, plant and equipment: 3 to 8 years
– Construction in progress and properties: only applicable in the case of an impairment loss
Intangible assets
Intangible assets are recognised at the cost of acquisition or production less accumulated amortisation and any impairment losses. Depreciation/amortisation is calculated using the straight-line method on the basis of the estimated useful technical and economic service life.
The service life is determined as follows:
– Rights of use: contract term
– Software and technical regulations: 3 to 5 years
– Intangible assets under development: only applicable in the case of an impairment loss
The merger losses (goodwill) resulting from the mergers on 3 January 2013 and 5 January 2015 are also recognised in this item. Goodwill is depreciated on a straight-line basis over 20 years and is reviewed annually for impairments.
Impairment losses
The value of property, plant and equipment and intangible assets is reviewed annually. If there is an indication of an impairment loss, the book value is reduced to the realisable value and an impairment loss is charged to the results of the period.
Construction in progress/intangible assets under development
Construction in progress and intangible assets under development are non-current assets that are not yet completed or not yet operational. All items of property, plant and equipment and intangible assets, including self-constructed assets, are classified as non-current assets. As of each balance sheet date, a review is performed to determine whether any construction in progress or intangible assets under development have to be impaired. These are recognised as impairment losses in the year of completion. Ordinary depreciation or amortisation of these assets begins once they are completed or are ready for operation.
Financial assets
Financial assets are measured at acquisition costs less any impairment losses. Employer contribution reserves without conditional renounced use are also recognised in financial assets.
Shareholdings
Shareholdings are measured at acquisition costs less any impairment losses. These include shareholdings with a capital share of over 20%, but which do not have a significant impact on the financial statements, as well as shareholdings with a capital share of less than 20% that do have a significant impact.
Inventory
Inventory includes waste material for maintaining the grid systems. Inventory is measured at the lower of acquisition cost or market price.
Accounts receivable
Accounts receivable are reported at their nominal value less any impairment losses required for business reasons.
Cash and cash equivalents
Cash and cash equivalents include cash in hand, cash at banks and deposits at banks maturing in 90 days or less. They are recognised at their nominal value.
Bonds
Bonds issued on the capital market are recognised at their nominal value. Deviations from the nominal value in the case of below- or above-par issues are recognised as accruals and deferrals and are reversed on a straight-line basis over the term of the bond.
Liabilities
Liabilities are recognised at their nominal value.
Provisions
Provisions are recognised if there is an obligation based on an event that took place prior to the balance sheet date, the amount and/or due date of which is uncertain but capable of being estimated.
Contingent liabilities
Contingent liabilities are measured as of the balance sheet date. A provision is reported if a cash outflow without a usable countervalue is probable and assessable. Otherwise, contingent liabilities are disclosed in the notes to the financial statements.
Interest on borrowed capital
Interest on borrowed capital is recognised as an expense in the period in which it arises.
Income taxes
Current income taxes are calculated based on the taxable results on an accrual basis.
Derivative financial instruments
Swissgrid may use derivative financial instruments to hedge against currency and market price risks. If the conditions are met, Swissgrid will apply hedge accounting to hedge expected future cash flows. The instruments used for this purpose will be disclosed in the notes to the financial statements until the underlying transaction is realised.
