Non adjusment event

"Not material" - by the definition of material - means it does not provide relevant information to primary users so it is NOT disclosed and has NO implications for the audit opinion or auditor's reporting. Can you please tell me which mock practice exam you are referring to? I can only think that the matter must be material if the answer suggests that it requires disclosure.

Such a contradictory answer cannot be correct - either it's material - so disclose - or it's not - so don't(!) If it is material AND it's adequately disclosed, the auditor could draw attention to the note disclosing the non-adjusting event after the reporting date in an EoM. If it's material and NOT adequately disclosed, the audit opinion should be qualified "except for".
