The auditor's report: key audit matters, qualified opinions, going-concern warnings and auditor changes

What you will learn

• The four types of audit opinion and what each means.
• How to use key audit matters (KAMs) as a guide to the softest balances.
• What a going-concern paragraph and an emphasis of matter signal.
• What to check when a company changes its auditor.

Explanation

The auditor's report (German: Bestätigungsvermerk) is a short document after the notes. It is the only independent voice in the report, so read it first.

Types of opinion

• Unmodified (unqualified) opinion – the statements give a true and fair view in all material respects. This is the normal case.
• Qualified opinion – true and fair "except for" one specific matter, such as an inventory count the auditor could not attend.
• Adverse opinion – the statements are materially misstated as a whole. Very rare for listed companies.
• Disclaimer of opinion – the auditor could not obtain enough evidence to form a view (German: Versagungsvermerk).

Any opinion other than unmodified is a hard red flag.

Key audit matters

Since International Standard on Auditing (ISA) 701, auditors of listed companies must describe key audit matters (KAMs): the areas that required the most attention and judgement. In Germany they are called besonders wichtige Prüfungssachverhalte; in the US the PCAOB equivalent is critical audit matters (CAMs). Each KAM states why it was significant, how the auditor addressed it and which note it relates to. Typical KAMs: goodwill impairment, revenue on long-term contracts, litigation provisions, valuation of inventories or deferred tax assets.

KAMs are not criticisms, but they are a free list of the softest numbers. Compare them year over year: a new KAM on receivables or inventories tells you where the auditor's concern has moved; a KAM that disappears while the balance stays large is also worth a note.

Going concern

Statements assume the company continues for at least twelve months. If events cast significant doubt on that, ISA 570 requires a section headed "Material uncertainty related to going concern" (German: wesentliche Unsicherheit im Zusammenhang mit der Fortführung der Unternehmenstätigkeit). The opinion can still be unmodified, so the warning is easy to miss.

An emphasis of matter paragraph points to something properly disclosed, such as a major lawsuit or restatement. It is weaker, but still means "read this note".

Auditor changes and rotation

Since the German Finanzmarktintegritätsstärkungsgesetz (FISG) of 2021, audit firms of German public-interest entities must rotate after at most ten years, and the lead audit partner after at most five. A rotation at the ten-year mark is routine. A change before the maximum, mid-year or shortly after a disagreement, is not. In the US, an auditor change triggers a Form 8-K (Item 4.01) that must state whether there were disagreements or "reportable events" in the last two years; read it. In Germany, the supervisory board's report and the AGM agenda explain the change; a switch from a large firm to a small, unknown firm is a classic warning sign from the fraud cases in lesson 12.

Worked example

Hypothetical example: an auditor's report contains two KAMs. KAM 1: a cash-generating unit (CGU) with a carrying amount of €1,000 million and a recoverable amount of €1,050 million; a 1 percentage point higher discount rate would reduce the recoverable amount by €90 million. KAM 2, going concern: cash €30 million, a €200 million bond maturing in nine months, an undrawn credit line of €50 million. Equity is €900 million, total assets €2,500 million.

1. Headroom on the goodwill test: 1,050 − 1,000 = €50 million, or 50 ÷ 1,000 = 5% of the carrying amount. That is thin.
2. Stress: recoverable amount 1,050 − 90 = €960 million. Impairment = 1,000 − 960 = €40 million.
3. Equity after impairment: 900 − 40 = €860 million. Equity ratio moves from 900 ÷ 2,500 = 36.0% to 860 ÷ 2,500 = 34.4%.
4. Refinancing gap: 30 + 50 − 200 = −€120 million. The company must refinance at least €120 million within nine months, before any operating cash flow is counted.

Neither KAM modifies the opinion. Together they say: the headline numbers depend on a 5% cushion and on the bond market. Deferred taxes and operating cash flow are ignored.

Common mistake

Practice activity

On paper, classify each case as unmodified, unmodified with material uncertainty, qualified, or disclaimer: (A) the auditor could not verify €8 million of inventory at one subsidiary of a €3 billion group and states "except for" this matter; (B) the auditor was denied access to the records of a subsidiary that makes up 60% of revenue; (C) the opinion is clean but a section says that the renewal of a €400 million facility due in six months has not been agreed; (D) a clean opinion with a KAM on revenue recognition. Then compute the twelve-month funding gap for a company with cash €25 million, forecast operating cash flow −€10 million, debt maturing €90 million and an undrawn facility of €40 million.

Key takeaways

• Read the auditor's report first and in full; anything other than an unmodified opinion is a hard red flag.
• KAMs are a free map of the most judgemental balances; track them year over year.
• A going-concern paragraph can sit inside an unmodified opinion; look for it explicitly.
• Early or unexplained auditor changes, and moves to small unknown firms, deserve investigation.
