What is the presentation and disclosure assertion?
Disclosure deficiencies are now the fastest-growing category of inspection findings across regulators. The AFM, FRC, PCAOB, and NBA have all flagged year-on-year increases since 2021. Most of these findings don't come from missing notes. They come from notes that are present but wrong or misleading in what they actually say.
ISA 315 .A190(c) breaks presentation and disclosure into four sub-assertions: occurrence and rights and obligations (disclosed events actually happened and pertain to the entity), completeness (all required disclosures are included), classification and understandability (information is described and classified so that it's clear), and accuracy and valuation (amounts and other data in disclosures are correct).
ISA 700.13 (b) ties these assertions directly to the auditor's opinion. The auditor concludes whether the FS are "presented fairly, in all material respects," which covers not just the face of the statements but every note and accounting policy disclosure. A clean opinion implicitly signs off on all four sub-assertions for every mat disclosure.
In practice, most teams test disclosures with a checklist that confirms whether each required note is present. That addresses completeness but leaves the other sub-assertions untested. A note can be present (completeness satisfied) but contain the wrong amount (accuracy fails), describe a transaction in misleading terms (understandability fails), or refer to an event that didn't actually occur (occurrence fails).
Key Points
- Covers the notes, accounting policies, the face of the statements, and supplementary disclosures. Every piece of information in the FS falls under this assertion category.
- Most files under-test disclosures relative to balances. Teams throw most of their hours at balance sheet and P&L line items and treat disclosures as a completion-phase tick box exercise.
- A disclosure that technically exists but buries the substance of the transaction doesn't satisfy classification and understandability.
- Regulators keep flagging this. AFM, FRC, PCAOB, and NBA reports all show year-on-year increases in disclosure-related deficiencies since 2021.
Why it matters in practice
The AFM has specifically called out the tick-box approach to disclosure testing as insufficient. Teams complete a disclosure checklist during the final review phase and treat it as evidence that P&D assertions have been addressed. ISA 330.6 requires the auditor to design further audit procedures whose nature, timing, and extent are responsive to assessed risks at the assertion level, including disclosure assertions. A checklist thrown together after the audit is basically done can't be responsive to risks identified during planning.
We've seen this on about half the engagements we review: teams also fail to test the accuracy of amounts within disclosure notes. A related party transactions note might list the correct parties (occurrence) and include all required transactions (completeness), but if the monetary amounts are transposed or aggregated wrong, the disclosure is materially misstated. You need to trace amounts in notes back to the underlying ledger entries and supporting docs with the same rigour you'd apply to balance sheet testing. Nobody would accept a PIOOMA number on a balance sheet line item, but that standard quietly drops when it comes to note disclosures. IAS 1.10 requires a complete set of FS including notes, and the opinion covers the notes as much as the primary statements.

Frequently asked questions
What are the four sub-assertions within presentation and disclosure?
ISA 315.A190(c) breaks them into occurrence and rights and obligations (disclosed events happened and pertain to the entity), completeness (all required disclosures are included), classification and understandability (information is described and classified appropriately), and accuracy and valuation (amounts and descriptions are correct).
Why are disclosure findings increasing?
Inspection findings on disclosure testing have increased year-on-year across AFM, FRC, PCAOB, and NBA reports since 2021. The main driver is that teams treat disclosures as a completion-phase tick box exercise rather than designing assertion-level procedures during planning, as ISA 330.6 requires.
Is a disclosure checklist sufficient for testing?
A checklist catches missing disclosures (completeness) but doesn't test whether present disclosures are understandable (classification) or whether amounts within notes are correct (accuracy). You need separate procedures for each sub-assertion. A note can be present but contain a transposition error that makes a figure materially wrong.
