The Group makes allowance for specific trade debtors that have clearly indicated financial difficulty and the likelihood of repayment has become impaired. More than 76% (2014: 74%) of the balance relates to customers that have not been impaired and meet their obligations within the Group’s payment terms.

Impairment losses are recorded in the allowance account until the Group is satisfied that no recovery of the amount owing is possible, at which point the amount is considered irrecoverable and is written off against the financial asset directly. Impairment losses have been included in merchandise and administration in profit or loss.

The carrying value of trade and other receivables approximate their fair value due to the short-term nature of the receivables.
