Transfers between stages are deemed to have taken place at the start of the reporting period, with all other movements shown in the stage in which the asset is held at 31 December, with the exception of those held within Purchased or originated credit-impaired, which are not transferrable. As assets are transferred between stages, the resulting change in expected credit loss of £493 million for drawn balances, and £8 million for undrawn balances, is presented separately as Impacts of transfers between stages, in the stage in which the expected credit loss is recognised at the end of the reporting period.


Net increase and decrease in balances comprise the movements in the expected credit loss as a result of new loans originated and repayments of outstanding balances throughout the reporting period. Loans which are written off in the period are first transferred to Stage 3 before acquiring a full allowance and subsequent write-off. Consequently, recoveries on assets previously written-off also occur in Stage 3 only.
