Further information on leasing expenses can be found in Note 45.

The HHLA Group regards the impairment losses on financial assets listed above as immaterial and has therefore decided not to show them separately in the income statement.

The previous year’s figure included expenses for the harmonisation of existing pension schemes, see Note 37.
