18.1Contingent liabilities

A number of legal proceedings and claims against the Zurich Airport Group in the context of its normal business activities are still pending. The company does not expect the amounts required to settle these lawsuits and claims to have a significantly negative impact on the consolidated financial statements and cash flow of the Zurich Airport Group.

Depending on future legal judgements, amongst others with respect to the southern approaches at Zurich Airport, noise-related liabilities may in future be subject to substantial adjustments, which would also require adjustments to the balance sheet. It is not yet possible to make a definitive estimate at the present time.

Zurich Airport Ltd. and Swiss Life AG are jointly and severally liable to third parties for the liabilities of the co-ownership structure the Circle and the ordinary partnership the Circle.
