30Other non-current liabilities

Connection fees and grid cost contributions consist of accrued connection fees and grid cost contributions received from customers, which are charged to profit or loss over a period of 35 years via net sales from goods and services in the Market Switzerland segment.

Advance payments on energy deliveries are recognised every year as income of CHF 745 thousand in the profit and loss item net sales from goods and services in the Market Switzerland segment. Minor divergences from the change recognised in the balance sheet result from rounding effects.

Other non-current liabilities include, among other things, negative goodwill of CHF 6,058 thousand (prior year CHF 0 thousand) from the acquisition of the remaining 50 per cent in Resol Ciminna S.r.l. The negative goodwill will be amortised over a useful life of five years (see Note 4).
