Trade receivables
Trade receivables are recorded at their original amount less provision for impairment. It is the Group’s policy to provide for 100% of the previous month’s aged receivables balances which are more than 180 days past due. Adjustments to the policy may be made due to specific or exceptional circumstances. The carrying amount of the receivable is reduced through the use of a provision account and movements in the provision are recognised in the income statement within cost of sales. When a previously provided trade receivable is uncollectable, it is written off against the provision.
