ACCA AAA December 2026: Key Audit Matter vs Emphasis of Matter – Stop Mixing Them Up

A Key Audit Matter (KAM) tells users what mattered most in the audit. An Emphasis of Matter (EOM) points users to something already disclosed. Mix them up in AAA and you lose the marks – and the opinion paragraph with them.

Why students keep confusing them

Both appear in the audit report. Both sit outside the opinion. Both are about "important matters". That is where the similarity ends, and where AAA reporting questions quietly punish you.

Under ISA 701, KAMs are the matters of most significance in the audit of the current period financial statements, chosen from the matters communicated with those charged with governance. They are required for listed entities. Each one explains why it was significant and how the auditor dealt with it.

Under ISA 706, an EOM refers to a matter already appropriately presented or disclosed in the financial statements that is fundamental to users' understanding. It is the auditor's judgement call, and it never changes the opinion.

The trap: a KAM cannot be used instead of a modified opinion, and a matter that causes a qualification is not a KAM. If the financial statements are misstated, you modify the opinion. Full stop.

Wrong answer vs correct answer

Scenario: a listed client has a material uncertainty over going concern. It is properly disclosed in the notes.

Wrong: "The auditor should include an Emphasis of Matter paragraph about going concern."

Correct: "Because the uncertainty is adequately disclosed, the opinion is unmodified, but ISA 570 requires a separate section headed 'Material Uncertainty Related to Going Concern'. It is not a KAM and not an EOM. If the disclosure were inadequate, a qualified or adverse opinion would follow."

One sentence of difference, several marks of difference.

What to do

1. Build a three-column table – KAM, EOM, Other Matter – with the ISA reference, the trigger, and whether the opinion changes. Redraw it from memory until it is automatic.

2. Ask "is it disclosed?" first. Not disclosed or disclosed wrongly means modified opinion. Properly disclosed and fundamental means EOM. Significant to the audit means KAM.

3. Apply it to the scenario. Name the entity type (listed or not), the ISA and the effect on the opinion in one tight sentence. Do not recite the standard.

Bottom line

AAA is a Professional level paper where applying a rule to the scenario beats reciting it. Check ACCA's published pass rates for the paper and you will see why precision matters.

Know which paragraph does which job, and the report writes itself.
