You were selected to lead the audit of Down Low Ltd for the year ended 30 September 2021. One of the assistants has been auditing the accounts receivable which has an ending balance of $3,800,000. This balance is made up of 2100 accounts receivable ledger account transactions.

It is noted in the working papers that 90 accounts were selected for checking. The basis of the sample selection was as follows:

The 20 largest accounts were selected

Haphazard sampling of the remainder

Any balance under $5,000 were regarded as too small to be chosen

The test performed on those items selected was to ask the customers to confirm in writing what they think the balance outstanding was at year-end (accounts receivable circularization).

The results of the test show the following:

	Number of items selected	Balance in sales ledger	Balance confirmed by debtor
No errors found (includes the 20 largest accounts)	65	$405,000	405,000
No confirmation by accounts receivable	7	16,000	16,000
Difference due to goods in transit to customers	6	14,500	8,200
Errors in calculating invoice total	2	21,000	12,000
Invoices posted to incorrect debtors ledger account	6	11,300	9,800
Invoice disputes with customer	9	12,000	7,500
Total	95	479,800	458,500
