What is material uncertainty related to going concern?
A mid-sized retailer loses 17% of revenue in one year. Its credit line is fully drawn. Net assets have eroded from several million to almost nothing. Management presents a turnaround plan that depends on a conditional bank facility and closing four stores, but two of those stores have no lease break clause until 2027. The engagement partner has to decide: does material uncertainty exist, or doesn't it? This is not a theoretical exercise. It's the single highest-stakes judgement call most audit partners make in a given busy season.
ISA 570.17 requires the auditor to determine whether material uncertainty (MU) exists after evaluating management's assessment and any mitigating plans. The evaluation is binary: MU either exists or it does not. There is no "close call" category in the standard, though ISA 570 (Revised 2024) paragraph A73 acknowledges that significant judgement may be required in borderline cases.
When MU exists and the entity discloses it adequately, the auditor includes a "Material Uncertainty Related to Going Concern" (MURGC) section in the report under ISA 570 (Revised 2024) paragraph 30. The opinion itself remains unmodified. When the entity does not disclose it adequately, the auditor expresses a qualified or adverse opinion under paragraph 36. Under the revised standard, the auditor must also include an explicit statement confirming whether MU exists or does not exist. That explicit statement requirement didn't exist under the current standard.
Key points
- Material uncertainty (MU) is a defined threshold, not a synonym for "doubt about going concern." The auditor must determine whether the threshold is met, not just whether concerns exist.
- The auditor reports MU even when the opinion is unmodified, through a dedicated MURGC section in the auditor's report. This is not a modification to the opinion.
- Failing to identify MU when it exists is one of the highest-profile audit failures a regulator can find, because the omission directly affects users' understanding of the financial statements.
- ISA 570 (Revised 2024) requires every auditor's report to include an explicit conclusion on whether MU exists, making the auditor's assessment visible to all users.
Why it matters in practice
It's not a tick box exercise. The going concern evaluation is the one area where treating it like a checklist will reliably get your file flagged. At firms like ours, the most common mistake we see is teams accepting a bank waiver letter at face value without testing whether the waiver conditions themselves introduced new uncertainty. The waiver exists, so the box is ticked. But the waiver is conditional on covenant compliance that the entity's own forecast shows it breaching within months.
MU exists in that scenario. The outcome depends on future events (covenant compliance and bank credit committee approval) that are genuinely uncertain. If the entity discloses this adequately, the auditor adds a MURGC section and the opinion stays unmodified. If not, the opinion is modified.
The FRC's Tier 2 and Tier 3 inspection results found insufficient procedures to evaluate the impact of loan covenant breaches on the continued availability of financing. Nobody enjoys the going concern write-up on a borderline file, but skipping the hard analysis is how files get flagged. Teams also treat "close to material uncertainty" as a reason to conclude that no MU exists, but ISA 570 (Revised 2024) paragraph A73 requires the auditor to document the specific factors that tipped the conclusion one way or the other. The file should tell a story: what indicators you identified, what mitigating factors you tested, what evidence you obtained, and why the conclusion went the way it did. A file that simply states the conclusion without the reasoning will not survive inspection.

Frequently asked questions
Is material uncertainty the same as doubt about going concern?
No. Material uncertainty is a defined threshold, not a synonym for doubt. Events or conditions may cast significant doubt on the entity's future, but if management's mitigating plans are feasible and the uncertainty is not material to users' decisions, the threshold is not met. Material uncertainty exists only when the outcome depends on future events that are genuinely uncertain and would affect how users interpret the financial statements.
What happens when material uncertainty exists but the entity discloses it adequately?
The auditor adds a 'Material Uncertainty Related to Going Concern' section to the report, but the opinion itself remains unmodified. The MURGC section draws users' attention to the disclosure in the financial statements. A modified opinion (qualified or adverse) applies only when the entity has not disclosed the uncertainty adequately or when the going concern basis of accounting is inappropriate.
