The company applies a payment rating assessment to each customer individually, which categorises customers into 13 payment categories. This assessment is integral to the calculation of doubtful debts. The 13 payment categories has been summarised into four main groupings of customers.

An analysis of the debtors book based on the payment ratings is set out below:
