If the auditor leaves a letter on internal control deficiencies, what should the manager and the accountant do?

The audit is over, and in addition to the report the auditor has also provided a list of deficiencies and recommendations. Does this letter affect the report and how should you respond to it? Short key points and a sample action plan.

When the auditor finishes the work, besides the auditor's report they leave one more document: the internal control deficiencies noticed during the audit and recommendations for fixing them. Many managers put it in a folder without reading it. That is a mistake.

Key points

  • This is not the report. The auditor's report is an opinion on the financial statements. The letter on deficiencies, by contrast, points to weak spots in processes.
  • The report does not change automatically. The auditor expresses an opinion depending on the materiality of misstatements in the statements. A deficiency in the letter does not by itself make the opinion qualified.
  • A deficiency missing from the letter does not mean there is "none". The auditor studies internal control to the extent needed for the audit and does not check it in full.
  • Give a written response to each item: do you agree, what action will be taken, who is responsible, by when.
  • Set priorities. Deficiencies that directly affect money, goods and payments are fixed first.
  • If a deficiency is not fixed, the next audit gets harder. If controls cannot be relied on, the auditor performs more substantive procedures: the sample gets bigger and the work takes longer.
  • Prove that it has been done. Before the next audit, prepare evidence for each item: an order, a new procedure, a signed reconciliation sheet.

Example: the "Navro'z Agro" action plan

The auditor's letter had three items. Chief accountant Feruza drew up a response table for each of them and submitted it to the director for signature.
