What are Summary Financial Statements?
Summary financial statements are condensed versions of an entity's audited annual financial statements, prepared for users who need a high-level overview without the full detail of a complete set. ISA 810 governs the auditor's engagement to report on them.
ISA 810.6 establishes a non-negotiable precondition: the auditor may only accept a summary engagement if the underlying financial statements have already been audited. There is no standalone engagement for summaries. The full audit must exist first.
The opinion the auditor expresses is narrower than a standard audit opinion. ISA 810.9 requires the auditor to evaluate whether the summary financial statements are consistent, in all material respects, with the audited financial statements. This is a consistency assessment, not a true-and-fair opinion. ISA 810.14 specifies the required contents of the report, including a reference to the full audited financial statements and the auditor's report thereon.
ISA 810.3 adds a practical requirement: the full audited financial statements must be made available to the intended users of the summary. If management intends to distribute summaries without making the full set accessible, the precondition for accepting the engagement is not met.
Key Points
- ISA 810.6 precondition: the underlying financial statements must already be audited before a summary engagement can be accepted.
- The opinion addresses consistency with the audited statements (ISA 810.9), not whether the summaries give a true and fair view.
- ISA 810.14 requires distinct report wording — using full-set audit language is an error.
- Full audited statements must be available to users of the summaries (ISA 810.3).
Why it matters in practice
The most frequent error is using the same report wording as a full-set audit report. ISA 810.14 requires distinct wording that addresses consistency with the audited financial statements, not truth and fairness. Copying the standard audit opinion template into a summary engagement report creates a misleading impression of the scope of work performed.
Teams sometimes accept summary engagements without verifying that the full audited financial statements will be made available to users. ISA 810.3 is clear on this point. If the entity plans to distribute the summary to shareholders without providing access to the complete set, the engagement should not be accepted under ISA 810.
Another practical issue arises when the full-set audit opinion is modified. The auditor must consider how that modification affects the summary report. A qualified opinion on the full set cannot simply be ignored when reporting on the summaries derived from those same statements.
