[1] This line item has been updated to include amounts from Other operating income relating to all sales of business operations; in the 2023 Annual Report and Accounts, this line item only reflected the disposal of our France retail banking business. The amount in 2024 includes a $1.0bn loss on disposal and a $5.2bn loss on the recycling in foreign currency translation reserve losses and other reserves arising on sale of our business in Argentina. This was partly offset by a gain of $4.6bn, inclusive of the recycling of $0.6bn in foreign currency translation reserve losses and $0.4bn of other reserves losses but excluding the $255m gain on the foreign exchange hedging (see footnote 4 above) on the sale of our banking business in Canada. The amount in 2023 primarily reflected losses due to restrictions impacting the recoverability of assets in Russia, partly offset by a gain on sale of our retail banking operations in France. The amount in 2022 included losses from classifying businesses as held for sale as part of a broader restructuring of our European business.
