Understanding the loan book

This question is open to anyone, but I'm guessing @Pioupiou will know the answer, so I'll shoot the question his way

There is a section called "Other commercial Receivables" (page 49) in the Credit Risk section of the annual report. In here, it shows a significant amount of debt that is Past 0-30days and Past 31-180days due...
I can only assume that this is because of the nature of the operation, being they provide finance using an invoice as security, then they receive payment from their customer's customer (i.e. the company who received the goods/services)

Further to this, there's an impairment of $2m against the Past 31-180days amount, yet in the presentation there was no impairment listed against the CRA business. Am I missing something here?
