Commercial partners have seen sales revenues fall significantly as a result of the coronavirus crisis, especially in retail, tax & duty free and food & beverage operations. The legal assessment is that the minimum annual rent agreed is not payable by lessees affected by the closures ordered by the authorities. Accordingly, the Zurich Airport Group adopted the same procedure as in the previous year and did not recognise the minimum rental income amounting to CHF 4.7 million for the period of the closures ordered by the authorities in financial year 2021 (2020: CHF 18.9 million).

In addition, further rent concessions for the period after the closures ordered by the authorities were discussed with the commercial partners concerned in the reporting period and solutions agreed. The rent concessions (rent waivers and contractual amendments such as staggered rents or lease term extensions) of CHF 40.9 million granted in this context for financial year 2021 (2020: CHF 32.6 million) were recognised as assets in accordance with IFRS 16 and will be amortised on a straight-line basis over the term of the relevant contracts. For the financial year, the amortisation amounted to a total of CHF 11.6 million (2020: CHF 6.3 million).
