[1] Interest income includes $93,388m (2023: $88,657m; 2022: $45,994m) of interest recognised on financial assets measured at amortised cost and $15,273m (2023: $12,134m; 2022: $6,293m) of interest recognised on financial assets measured at fair value through other comprehensive income. It also includes a net $237m loss related to the early redemption of legacy securities.

[2] Interest income is calculated using the effective interest method and comprises interest recognised on financial assets measured at either amortised cost or fair value through other comprehensive income.

[3] Interest expense includes $72,594m (2023: $62,095m; 2022: $20,798m) of interest on financial instruments, excluding interest on debt instruments issued by HSBC for funding purposes that are designated under the fair value option to reduce an accounting mismatch and on derivatives managed in conjunction with those debt instruments included in interest expense.

[4] Includes a $255m gain (2023: $315m loss) on the foreign exchange hedging of the proceeds from the sale of our banking business in Canada and a $114m mark-to-market gain (2023:nil) on interest rate hedging of the portfolio of retained loans post sale of our retail banking business in France.

[5] Gain recognised in respect of the acquisition of SVB UK.

[6] 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.

[7] Other operating income/(expense) includes a loss on net monetary positions of $1,187m (2023: $1,667m; 2022: $678m) as a result of applying IAS 29 ‘Financial Reporting in Hyperinflationary Economies’. 

[8] Net operating income before change in expected credit losses and other credit impairment charges also referred to as revenue.

[9] Includes depreciation of the right-of-use assets of $711m (2023: $663m; 2022: $717m).
