23. Property, plant and equipment

Additions result largely from investments in resurfacing, the procurement of handling equipment and storage capacities at the container terminals in Hamburg and the acquisition of wagons and locomotives in the Metrans Group.

Disposals in the financial year under review mainly relate to resurfacing and to the sale/scrapping of technical equipment and machinery.

Changes to the consolidated group in the financial year relate solely to the subsidiary HHLA TK Estonia AS, Tallin, Estonia, which was included in the consolidated financial statements for the first time.

The effects of changes in exchange rates mainly include the opposing exchange rate changes of the Polish and Ukrainian currencies.

Impairment losses on property, plant and equipment totalling € 2 thousand (previous year: € 0 thousand) were recognised in the reporting year.

Buildings, surfacing and movable non-current assets with a carrying amount of € 7,333 thousand (previous year: € 1,997 thousand) have been pledged as collateral in connection with loans taken up by the Group.

Regarding existing restrictions on the disposal and use of buildings in connection with the letting of the associated properties from the Free and Hanseatic City of Hamburg, see the explanatory remarks on the lease agreements in Note 45.
