The accrued income as at 31 December 2020 has been fully billed in 2021. The Group applies the IFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables. To measure the expected credit losses, trade receivables and accrued income have been grouped based on shared credit risk characteristics and the days past due. The expected loss rates are based on the payment profiles of sales over a period of 36 months before the end of the period and the corresponding historical credit losses experienced within this period. The historical loss rates are adjusted to reflect current- and forward-looking information on macroeconomic factors affecting the ability of the customers to settle the receivables. On that basis, the loss allowance for trade receivables is determined as follows: Gross trade Impairment Net trade receivables provision receivables Trade receivables £000 £000 £000 Not passed due 0.20-0.25% 211,214 479 210,735 Past due one day to 30 days 0.40-0.50% 45,117 212 44,905 Past due 31 days to 60 days 0.60-1.00% 9,994 81 9,913 Past due 61 days to 90 days 0.80-2.00% 3,525 45 3,480 Past due more than 90 days 1.00-7.50% 2,966 252 2,714 Individual debtors in default up to 100% 4,251 4,251 – Balance at 31 December 2021 277,067 5,320 271,747 Gross trade Impairment Net trade receivables provision receivables Trade receivables £000 £000 £000 Not passed due 0.20–0.25% 126,323 287 126,036 Past due one day to 30 days 0.40–0.50% 25,047 120 24,927 Past due 31 days to 60 days 0.60–1.00% 3,666 32 3,634 Past due 61 days to 90 days 0.80–2.00% 1,999 30 1,969 Past due more than 90 days 1.00–7.50% 3,307 279 3,028 Individual debtors in default up to 100% 2,618 2,614 4 Balance at 31 December 2020 162,960 3,362 159,598 148 S4Capital Annual Report and Accounts 2021
