38 Lessor relationships Finance leases. Deutsche Telekom is a lessor in connection with finance leases. Essentially, these relate to the leasing of routers and other hardware, which Deutsche Telekom provides to its customers for data and telephone network solutions. Deutsche Telekom recognizes a receivable in the amount of the net investment in the lease. The lease payments made by the lessees are split into an interest component and a principal component using the effective interest method. The lease receivable is reduced by the principal received. The interest component of the payments received is recognized as finance income in the income statement. Under business models in which Deutsche Telekom is classified as a manufacturer or dealer within the meaning of IFRS 16, revenue is disclosed similar to the accounting of revenue in accordance with IFRS 15. The gain or loss on the sale of the finance lease is realized in the amount of the difference between the revenue and the carrying amount of the underlying asset less the present value of the unguaranteed residual value. The finance income (interest income) is subsequently also recognized under the lease revenue.

If Deutsche Telekom is a lessor in connection with operating leases, it continues to recognize the leased assets in its statement of financial position. The lease payments received are recognized in profit or loss. The leases mainly relate to the rental of cell sites, building and co-location space, unbundled local loop lines, and terminal equipment. The regulator requires Deutsche Telekom to make co-location space and unbundled local loop lines available to competitors. In contrast to unregulated products, the residual value risk for these assets is rather low because competitors are economically dependent on the use of these assets. In the unlikely event that co-location space and unbundled local loop lines are not leased, Deutsche Telekom will try to find new tenants for the vacant space or unleased lines. In the case of its own cell sites, Deutsche Telekom will also strive to continue leasing – where possible – all of the free space that it does not itself occupy. The aim here is to reduce the vacancy rate of unused space as far as possible by re-letting and to spread the cost. Where terminal equipment is leased in the United States operating segment, customers are entitled to receive a new device once per month during the term of the lease. On receipt of the new device or at the end of the contract, the customer either returns or purchases the equipment. The purchase price at the end of the lease is set at the commencement of the lease and is equal to the estimated residual value of the equipment. This is based on the estimated market value of the device at the end of the contract. The contracts do not contain any residual value guarantees or variable lease payments, nor do they contain any restrictions or covenants. Terminal equipment returned by customers is prepared for sale in the secondary market or for use as a replacement for defective devices. This reduces the residual value risk of the returned equipment. Operating leases exist for the following items of property, plant and equipment: (XLS:) Download millions of € Land and buildings Technical equipment and machinery Total COST AT DECEMBER 31, 2017 112 1,543 1,656 Currency translation 0 50 50 Changes in the composition of the Group 0 2 2 Additions 0 932 932 Disposals (13) (945) (958) Change from non-current assets and disposal groups held for sale 0 0 0 Reclassifications 0 16 16 AT DECEMBER 31, 2018 99 1,599 1,697 Currency translation (2) 14 11 Changes in the composition of the Group 0 0 0 Additions 0 978 978 Disposals (18) (1,027) (1,045) Change from non-current assets and disposal groups held for sale 0 0 0 Reclassifications 1 15 16 AT DECEMBER 31, 2019 80 1,578 1,657 ACCUMULATED DEPRECIATION AND IMPAIRMENT LOSSES AT DECEMBER 31, 2017 (85) (726) (811) Currency translation 0 (22) (22) Changes in the composition of the Group 0 0 0 Additions (depreciation) (2) (897) (899) Additions (impairment) 0 0 0 Disposals 12 667 679 Change from non-current assets and disposal groups held for sale 0 0 0 Reclassifications 0 (8) (7) Reversal of impairment losses 0 0 0 AT DECEMBER 31, 2018 (76) (984) (1,060) Currency translation 2 (10) (9) Changes in the composition of the Group 0 0 0 Additions (depreciation) (3) (555) (558) Additions (impairment) 0 0 0 Disposals 17 787 804 Change from non-current assets and disposal groups held for sale 0 0 0 Reclassifications 1 1 2 Reversal of impairment losses 0 0 0 AT DECEMBER 31, 2019 (59) (762) (821) NET CARRYING AMOUNTS At December 31, 2018 23 614 637 AT DECEMBER 31, 2019 21 816 837 The future minimum lease payments arising from non-cancelable operating leases are as follows: (XLS:) Download millions of € Maturity Dec. 31, 2019 Within 1 year 876 In 1 to 2 years 589 In 2 to 3 years 32 In 3 to 4 years 365 In 4 to 5 years 21 After 5 years 697 2,581 (XLS:) Download millions of € Maturity Dec. 31, 2018 Within 1 year 704 In 1 to 3 years 448 In 3 to 5 years 311 After 5 years 452 1,915 The increase in the future minimum lease payments mainly results from the higher number of cell sites and the related conclusion of new leases. Furthermore, the introduction of the IFRS 16 accounting standard also resulted in certain business models being classified as operating leases. schließen ULL - Unbundled Local Loop Competitors whose own networks do not reach into customers’ premises can rent unbundled local loop lines from Deutsche Telekom. Their networks end at the local exchanges. The ULL bridges the distance between the local exchange and the termination point on the customer’s premises or in their home, so it is also known as the “last mile.”
