The Group leases several assets including buildings (offices, shops, technical rooms_), mobile sites (i.e. facilities to install mobile communication equipment) and fleet (management cars, utility cars & bikes). These leases generally have lease terms between 4 and 15 years. The average lease term is 9 years. The carrying amounts of right-of-use assets recognized and the movements during the period are disclosed below In 2021 the mobile site contracts continued (in general) to be extended. As a result of the digitalization process, the number of stores further decreased, while other building contracts were extended. Car contracts were generally not extended but replaced by new contracts. In 2022 we noticed the same trends. However, at the same time, two new groups of assets have emerged. bikes on the one hand and cloud infrastructure from our partnership with HCL on the other hand. The bikes (representing 1% of the Fleet figures) are optional leases for employees meeting specific criteria (like opting for an electric or hybrid company car). Partnership with HCL Technologies In 2021 Proximus entered a partnership with HCL Technologies whereby that company operates and maintains Proximus' private cloud infrastructure. The partnership foresaw a transition phase, that started in October 2021 and that was finished in February 2022. HCL and Proximus concluded an asset financing arrangement (nominal amount of EUR 65 million) for the infrastructure that remains in the Proximus data centers and under Proximus control. On 31 December 2022 the carrying amount is EUR 50 million (see Note 5. "Technical Equipment") New cloud infrastructure that was purchased by HCL (nominal amount of 18 million) and used by it in the context of the partnership. qualified as a lease. On 31 December 2022 the carrying amount of the right of use is EUR 17 million (See "Other" in the table above).
