Gain/(loss) on disposal of operations		$ 100

[1] In 2024, the amount 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 $0.3bn 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.

[2] Includes the recycling of a $0.2bn foreign currency translation reserves loss as a result of the dilution of our shareholding in BoCom.
