one traced to cash receipts,one to a vendor's credit memo for part of the amount and cash receipts for the rest,and one to a vendor's credit memo.
Two of the amounts confirmed differed from the amount on the list, but the auditors did not seek an explanation for the differences because the amounts were not material.
The rest of the credits were tested by selecting 30 items (several from each page of the list). Fourteen of the items were supported by examining the vendors for the promotional allowances.
