Response rate = received / sent (by count and by value)
Coverage = (responses + alternative procedures) / sent or / balance

The formulas

  • Response rate = received / sent (by count and by value)
  • Coverage = (responses + alternative procedures) / sent or / balance

How it works

AU-C 505 requires alternative procedures for each non-response to positive confirmation requests, and evaluation of exceptions to see whether they indicate misstatements. Uncleared non-responses and exceptions feed the misstatement evaluation for the account.

The tool tracks progress on the confirmation workpaper. It does not set a required response rate: the standard has none. SAS No. 150, External Confirmations, amends AU-C 505 for audits of periods ending on or after December 15, 2028. Audits of issuers follow PCAOB AS 2310 instead.

Common questions

What alternative procedures fit receivables?

Subsequent cash receipts matched to specific invoices, shipping documents and the customer's order.

When are alternative procedures not enough?

When a confirmation response is necessary to obtain sufficient appropriate evidence, a non-response requires the auditor to evaluate the effect on the opinion.

Are timing differences exceptions?

They are differences to investigate. Once traced to cutoff-correct items they are not misstatements.
