[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] 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’. 

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

[7] The debt instruments, issued for funding purposes, are designated under the fair value option to reduce an accounting mismatch.

[8] The amounts recorded within profit before tax with respect to dividend income from subsidiaries and impairment/reversal of impairment of subsidiaries are not subject to tax.

[9] The tax credit in 2022 includes $2.2bn arising from the recognition of a deferred tax asset from historical tax losses in HSBC Holdings. This was a result of improved profit forecasts for the UK tax group, which accelerated the expected utilisation of these losses and reduced uncertainty regarding their recoverability.
