Further information on this is also planned. The effects are detailed in the explanations following this table. The reform of interbank offered rates (IBORs) is currently generating uncertainty regarding the timing of implementation and the precise content of the planned changes. Deutsche Telekom is affected by this uncertainty in its hedging of interest rate and currency risks in designated fair value and cash flow hedges where certain IBORs are part of the hedging relationship (EURIBOR, USD-LIBOR, GBP-LIBOR, AUD-LIBOR, CHF-LIBOR, HKD-LIBOR, and NOK-OIBOR). Group Treasury continuously analyzes the latest developments and takes any steps needed to transition to the new interest rate benchmarks. Deutsche Telekom does not expect the changes in the benchmark rates to have a material impact. For information on hedging relationships, please refer to the section “Disclosures on financial instruments.” For more information on standards, interpretations, and amendments that have been issued but not yet applied, as well as disclosures on the recognition and measurement of items in the statement of financial position and discretionary decisions and estimation uncertainties, please refer to the section “Summary of accounting policies” in the notes to the consolidated financial statements in the 2019 Annual Report. Changes in accounting policies and changes in the reporting structure Deutsche Telekom did not make any major changes to its accounting policies or reporting structure in the reporting period.
