Alternative Procedures for Unconfirmed Balances: Designing Evidence That Addresses the Risk
Practical audit procedures, evidence points, and documentation considerations for Hong Kong audit teams.
Practice Overview
Last updated: 16 September 2026
An unconfirmed balance is an evidence challenge, not a routine file-completion point. Where a requested external confirmation is not returned, cannot be relied upon, or cannot be obtained, the audit team should reassess the assertions and risks that remain unaddressed and design alternative procedures that are capable of producing relevant, reliable evidence. At a high level, this reflects the HKSA 505 focus on external confirmations and the broader HKSA 500 evidence concepts: the work performed should be sufficient and appropriate in the circumstances, rather than merely different from the original confirmation request.
For Hong Kong audit practices, the quality risk often arises when generic procedures, client-prepared schedules, or management explanations are treated as substitutes for independent evidence. The file should make clear why the selected response addresses the balance, period and assertion; what evidence was obtained; how its source and reliability were assessed; and how contradictory information or exceptions were resolved. This general technical education is not engagement-specific audit, legal, tax or regulatory advice. If a firm uses audit technology, including Audit Program 4.1 (AP4.1), professional judgement, supervision and evaluation of the evidence remain the engagement team’s responsibility.
Key Audit Issues
The reason for non-confirmation may change the risk assessment
A non-response, an undeliverable request, a refusal, a late response and a response of uncertain origin do not carry the same implications. The team should understand and document the cause, consider whether it indicates a risk about the balance or confirmation process, and determine whether further work, a broader sample or escalation is warranted.
Alternative work must address the specific assertion
A balance may involve existence, rights and obligations, completeness, accuracy, valuation, cut-off or presentation considerations. Inspecting a subsequent transaction may be persuasive for one assertion but weak for another. The alternative response should be tailored to the financial-statement area, the relevant period and the assertion left unsupported.
Evidence from management requires careful corroboration
Client schedules, internal correspondence and oral explanations can help direct audit work, but their reliability depends on source, controls, consistency and the risk context. Where risk is elevated, the team should seek corroboration from appropriately independent sources and challenge information that is incomplete, unusual or inconsistent.
Timing and cut-off can limit the value of subsequent evidence
Subsequent settlement or activity may support aspects of a year-end balance, but it may not by itself establish the amount, condition or entitlement at the reporting date. The team should link subsequent evidence back to the year-end population, investigate intervening movements and consider cut-off, reversals, credits, disputes and post-year-end adjustments.
Documentation must show an evaluable chain from risk to conclusion
Under the high-level documentation concepts in HKSA 230, a reviewer should be able to understand the objective, nature, timing and extent of the work, the source records inspected, results, exceptions, significant judgements and conclusion. A generic statement that alternative procedures were performed does not demonstrate how the evidence gap was resolved.
Tailored Audit Procedures
Reframe the evidence objective before selecting alternatives
Identify the unconfirmed population or item, the relevant assertions, assessed risks, materiality considerations and the precise evidence unavailable from confirmation. Record why the original request did not yield usable evidence, then design procedures that directly respond to the remaining evidence need rather than applying a standard substitution.
Perform controlled follow-up on the original confirmation process
Where appropriate, verify contact details using an independently obtained source, maintain control over dispatch and return arrangements, follow up directly through an appropriate channel, and assess the provenance and authenticity of any response received. Investigate unusual routing, inconsistent contact information or indications that management may have influenced the process.
For cash and bank balances, reconcile reliable post-year-end evidence to year end
Where relevant, inspect bank statements or other records obtained through a reliable source, agree the reported balance to the bank reconciliation, test material reconciling items and trace significant subsequent receipts, payments and transfers. Consider whether the work addresses existence, rights and any restrictions at the reporting date, not solely later cash movement.
For receivables and contract-related balances, combine settlement and underlying transaction evidence
Test subsequent cash receipts to bank records and remittance information, then trace them to the specific year-end invoices or balances. Inspect relevant contracts, delivery or acceptance evidence, credit notes, correspondence and dispute information, and test sales cut-off where applicable. Investigate settlements that differ from the recorded amount or occur through unusual channels.
For payables, deposits and other third-party balances, test the direction of the assertion
Select procedures appropriate to the balance and assertion, such as inspecting supplier statements, invoices, goods-received records, payment evidence, agreements, custodial records or subsequent settlement. For completeness risks, consider searching post-year-end payments and unmatched receiving records; for rights or existence risks, inspect the underlying agreement and independent support.
Evaluate results cumulatively and extend work when necessary
Compare evidence obtained with the ledger, confirmation exceptions, prior-period patterns and other audit evidence. Resolve contradictions, quantify identified differences, consider implications for the risk assessment and other related balances, and expand testing, obtain consultation or communicate significant matters where the evidence remains insufficient or reliability is in doubt.
Controls and Evidence to Consider
Controlled confirmation log
Retain a complete log of the population, selection rationale, verified recipient details, request date, dispatch method, follow-up, return channel, responder identity, authenticity checks, response status and exceptions. This creates traceability over the confirmation process rather than relying on a copied request alone.
Assertion-to-procedure evidence matrix
For each material non-response or unreliable response, link the unaddressed assertion and risk to the alternative procedures, source evidence, results and conclusion. The matrix helps demonstrate why the response was tailored and highlights assertions that remain unsupported.
Source, testing and exception trail
Working papers should identify the population, items selected, selection basis, records inspected, relevant dates, preparer and reviewer, procedures performed, results and exceptions. Preserve or clearly reference source documents and explain how discrepancies, contradictory evidence and management explanations were evaluated.
Focused supervision and completion review
Require timely review of material unconfirmed balances, high-risk confirmations and significant alternative procedures. The review should challenge whether the work addresses the asserted risk, whether evidence is reliable and complete, whether exceptions have been resolved, and whether the final conclusion is consistent with the evidence on file.
