Contingent liabilities for antitrust proceedings
With regard to the contingent liabilities reported in the 2017 consolidated financial statements in connection with antitrust proceedings, Swisscom is of the opinion that an outflow of resources is unlikely and, as before, has therefore not recognised any provisions for this in the consolidated financial statements as at 31 March 2018.
