Divesting without an audit is like selling a house without a valuation — the buyer “chips” the price and the seller has nothing to argue with. When a Chinese investor divests, independent audit protects value for both sides: establishing real value, cleaning tax duties, and reassuring banks on remittance. This article covers the needed audit types and how to organise them.
1. Three purposes of divestment audits
- Value establishment: audited financials ground the valuation — buyers struggle to “chip” prices when figures are independently confirmed;
- Tax clean-up: tax audits uncover underpaid taxes and filing errors — fix before finalisation, avoiding later back-taxes;
- Liquidation support: on dissolution, the audit report grounds asset distribution and is required in many procedures;
- Bank confidence: banks releasing funds offshore feel “safer” with a clean audit report.
2. Financial-statement audit: mandatory or voluntary
Under Vietnam’s Law on Independent Audit 2011/QH13, foreign-invested enterprises must have annual financial statements audited. On divestment:
- Annual audit: for mid-year exits, audit statements to the exit date (interim audit) — don’t wait for year-end;
- Transaction-purpose audit: the parties agree to engage auditors for valuation — costs usually borne by the seller or split;
- Dissolution audit: the final-period audit report forms part of the dissolution dossier;
- Choose a licensed Vietnamese audit firm — unlicensed reports have no legal standing.
3. Tax audit (tax due diligence): the most important one
- Review 3–5 years: check VAT, CIT, PIT and contractor-tax filings for unfinalised years;
- Spot risks: non-deductible expenses, misapplied incentives, undeclared related-party transactions;
- Estimate top-up taxes: feed into price negotiation (buyer deducts from price) or fix upfront;
- Tax audit ≠ financial audit: financial audits opine on “true and fair” — tax audits drill into each risk item. Do both.
4. Independence: who engages the auditor
- No sharing: the buyer’s auditor cannot “objectively” audit for the seller — each side engages its own where interests conflict;
- Auditors must be independent of both sides per professional ethics — no financial ties, no conflicting advisory services;
- Agreed scope: both sides agree the audit scope (period, content) before engaging — avoiding post-audit rejection;
- Information access: the buyer’s auditor gets data-room access — with NDAs for confidential information.
5. Asset audit: when value sits in assets
- For manufacturers (plant, machinery): combine audit with fixed-asset valuation;
- Physical inventory: reconcile books to existing assets — catching “ghost” assets or disposed-but-unrecorded ones;
- Inventory: count and assess recoverability (slow-moving, obsolete stock needs provisions);
- Receivables/payables: reconcile — uncovering bad debts and “ghost” debts.
6. Audit timing: don’t be late
- Ideal: audit done before price negotiation — the seller leads with clean figures;
- Acceptable: audit parallel to negotiation — results as a contract condition;
- Late: audit after signing — issues found too late; only price chips or indemnities remain;
- Duration: a full audit takes 4–8 weeks — build into the exit timeline.
7. Audit costs: who pays
- Annual financial audit: the company pays (its legal duty);
- Transaction-purpose audit (vendor DD): usually the seller — serving the seller’s interest (proving value);
- Buyer’s audit (buyer DD): the buyer pays;
- Tax audit: negotiated — often split or seller-paid to “clean house” before sale;
- Fees depend on scale and complexity — quote from 2–3 firms.
8. Handling findings: what when issues surface
- Price adjustment: each dong of top-up tax, each bad debt found = deducted from price — a post-audit price adjustment mechanism belongs in the contract;
- Seller self-remediation: pay top-up taxes, book provisions — “clean then sell” fetches better prices;
- Warranties and escrow: for unresolved items (tax under inspection), hold back consideration + seller warranties;
- Don’t hide results: concealing a problematic report, discovered later = lost trust + indemnity grounds.
9. Audit and transfer pricing: the hot spot for Chinese investors
- Companies transacting with Chinese parents/affiliates (raw materials, management fees, loans) face transfer-pricing review;
- Tax audits must include a transfer-pricing file review: is documentation complete, are prices market-based;
- Risk: price reassessment → CIT back-taxes + penalties — potentially huge;
- Fix: complete transfer-pricing documentation before divesting — small cost vs back-taxes.
10. Archiving audit files
- Audit reports, management letters, working papers — keep at least 10 years;
- Both seller (Chinese investor) and buyer keep a set — for later tax finalisation and ODI closure;
- The auditor’s management letter often holds more important findings than the formal report — don’t skip it;
- Electronic + paper — stored in two places.
11. Choosing the audit firm: criteria
- Valid practising licence in Vietnam;
- Experience auditing FDI enterprises, especially in the company’s sector (manufacturing, energy…);
- Experience with Chinese investors — understanding related-party models with Chinese parents;
- Independence from both deal sides;
- Chinese/English capacity — bilingual reports serving both sides and banks.
12. Forensic audit: when fraud is suspected
Sometimes diligence smells wrong — missing documents, round-number transactions, managers who “can’t find” records. A forensic audit goes beyond the standard audit:
- Scope: targeted at suspected fraud areas — procurement kickbacks, phantom employees, related-party siphoning, cash skimming;
- Techniques: data analytics (Benford’s law, duplicate detection), lifestyle checks on key personnel, supplier verification visits;
- Privilege: engage the forensic team through external counsel so findings are protected by legal privilege — critical if the matter ends in litigation;
- Cost and time: 2–3× a standard audit; 6–12 weeks — but uncovering a fraud before closing is worth multiples of the fee;
- Outcome options: price reduction, seller indemnity, walking away — or reporting to authorities in serious cases.
13. Agreed-upon procedures: the lighter alternative
When a full audit is overkill — small deal, clean history, time pressure — agreed-upon procedures (AUP) offer a middle path:
- The parties agree specific checks (e.g. “verify the 20 largest receivables”, “reconcile tax filings for 2 years”) — the auditor reports findings only, no opinion;
- Cheaper and faster: typically 30–50% of a full audit’s cost, 2–3 weeks;
- Limitations: AUP doesn’t catch what wasn’t asked to check — the scope must be designed by someone who knows where bodies are buried;
- Best for: confirming specific seller representations (e.g. “no overdue tax exceeds X”) rather than open-ended assurance.
AUP plus targeted warranties often gives 80% of a full audit’s protection at half the cost — a pragmatic choice for mid-size exits.
Pre-divestment audit scope
Commission a sell-side audit before the Chinese investor’s exit — it pays for itself in price protection:
- Tax health check: the audit should stress-test transfer pricing, VAT refunds, and incentives actually used;
- Contingent liabilities: quantify unrecorded exposures — labour disputes, pending assessments, warranty claims;
- Related-party balances: reconcile every intercompany balance — buyers discount what they can’t verify;
- Asset verification: physically verify key assets — book values and reality diverge over time;
- Report format: ask for a findings-and-impact format the buyer’s team can diligence against.
Dealing with audit adjustments
Audits find things. How you handle adjustments affects both price and timetable:
- Triage: sort findings into price adjustments, warranties, and walk-away issues;
- Voluntary correction: fix clear tax errors before closing — disclosed corrections cost less than discovered ones;
- Escrow sizing: link the escrow amount to the quantified adjustments, not to a round number;
- Management responses: get written management representations on each material finding;
- Re-audit: for large adjustments, run a follow-up review confirming the fix before funds flow.
