[1] From 2022, Barclays Bank PLC has changed its presentation of transfer pricing arrangements to align with the policies being used across rest of the Barclays Group. The change impacts transfer pricing and sales credits earned or paid when affiliate entities act as recipients or payers of such transactions. Transfer pricing and sales credits will be shown within net trading income or fees and commission income depending on the nature of the transaction. Transfer pricing and sales credits previously recognised in fees and commission expense (2021:£2,072m; 2020: £2,241m) have been re-presented, resulting in a reduction in net trading income (2021:£789m; 2020: £1,296m) and fees and commission income (2021:£1,283; 2020: £945m). There is no impact on total income reported.
