A legal, tax and financial deal structure diagram gives every transaction workstream one shared view of an acquisition. Buyers, sellers, investors and advisers can use it to test whether the proposed Vietnam M&A structure is legally executable, tax-efficient and financially fundable before drafting becomes too advanced.
The diagram should identify every entity, ownership percentage, payment route, financing source, tax step, approval and closing dependency. It should be prepared early, tested against due diligence findings and updated whenever the transaction changes.
Why a deal structure diagram is essential
Transaction documents often describe the deal from one legal perspective, while tax models and financing papers use different terminology. A visual map exposes inconsistencies immediately. It also helps decision-makers understand why a step is required and what happens if an approval, payment or restructuring action is delayed.
Start after the initial commercial terms are known but before the definitive documents are substantially negotiated. For comparison of the two principal acquisition forms, see our guide to share deals versus asset deals in Vietnam.
1. Define the diagram’s scope
State whether the document shows the current structure, the closing structure, the post-closing structure or all three. A single crowded page is less useful than a short sequence labelled “before,” “closing steps” and “after.” Add the transaction name, date, version number, preparer and assumptions so recipients know which structure was approved.
2. Identify every entity and jurisdiction
Include the ultimate investor, acquisition vehicle, intermediate holding companies, lenders, target, subsidiaries, sellers and any escrow agent. For each entity, show its full legal name, jurisdiction, entity type and ownership percentage. Use consistent colours for buyer-side, seller-side, target-group and financing entities.
If an acquisition vehicle is contemplated, align the map with the considerations described in our guide to using an SPV for a Vietnam acquisition.
3. Show current and proposed ownership
Ownership arrows should identify direct shareholdings, voting rights and any material difference between legal and economic ownership. Mark whether the buyer will acquire 51%, 65%, 75% or 100%, and flag minority protections, reserved matters or options that affect control.
4. Map the consideration flow
Use separate arrows for purchase price, shareholder-loan repayment, target debt refinancing, escrow deposits, retention amounts, fees and tax withholding. Label the payer, payee, amount or formula, currency, account type and timing. The funds flow should match the approach explained in our guide to cross-border purchase price payments into Vietnam.
5. Add the acquisition financing
Show equity contributions, acquisition debt, guarantees, security, refinancing and any permitted upstream or downstream funding. Identify which entity borrows, which provides security and where funds are applied. Confirm that the diagram does not assume financial assistance, dividend capacity or security rights that require additional analysis.
6. Overlay the tax consequences
For each material step, note potential transfer tax, capital-gains tax, withholding, value-added tax, registration charges and deductibility issues. Identify the taxpayer, filing party, payment deadline and source of cash. Where tax depends on allocation, coordinate with the purchase price allocation.
The diagram is not a substitute for a tax memorandum. It is a control document that ensures the memorandum addresses every transfer and payment shown in the legal structure.
7. Add regulatory approvals and licences
Place approvals beside the step they enable. These may include merger control, foreign investment, sector approvals, amendments to enterprise or investment registrations, land-related consents and lender approvals. Use a legend distinguishing pre-signing, pre-closing and post-closing actions.
8. Show pre-closing restructuring
If assets, employees, contracts, licences or subsidiaries must move before closing, display each transfer separately and show the resulting ownership structure. State the responsible party, required consent and tax assumption. Compare the steps with our guide to pre-closing restructuring of a Vietnamese target.
9. Convert the structure into a closing sequence
Number the steps in the order they occur: capital contribution, financing drawdown, escrow funding, share transfer, debt repayment, document release and registration. Identify conditions that must be satisfied before each step and documents that evidence completion. A separate closing flowchart can be attached when simultaneous steps are too detailed for the principal diagram.
10. Reconcile the diagram with transaction documents
Check every arrow and entity against the term sheet, SPA, disclosure letter, escrow agreement, facility documents, tax analysis and corporate approvals. Ownership percentages, defined terms, currencies and amounts should match. Any difference must be intentionally resolved rather than left to the closing team.
11. Run a multidisciplinary review
Legal counsel should confirm execution steps and approvals; tax advisers should validate liabilities and filing responsibilities; finance advisers should confirm sources, uses and accounting; bankers should validate account routes; and management should confirm operational dependencies. Record unresolved issues directly on the diagram or in an attached assumptions log.
12. Apply version control
Deal structures change frequently. Use a clear version number, date and status such as “discussion draft” or “approved structure.” Maintain one controlled copy and a change log. Circulating several unlabelled versions can cause documents to be drafted against different commercial assumptions.
Practical quality-control checklist
- Current, closing and post-closing structures are distinguishable.
- Every entity has a legal name and jurisdiction.
- Ownership and voting percentages are accurate.
- Every payment has a payer, payee, currency and purpose.
- Financing, security and debt repayment are shown.
- Tax liabilities and filing responsibilities are assigned.
- Approvals are linked to the steps they enable.
- Restructuring actions and dependencies are numbered.
- The map matches all principal deal documents.
- The version and assumptions are clearly controlled.
Common Pitfalls When Building a Deal Structure Diagram
Even experienced deal teams get their deal structure diagram wrong in predictable ways. The most common pitfall is scope creep: adding entities and jurisdictions that are not yet locked because term sheets are still open. A diagram built too early, without marking which elements are draft assumptions, can be mistaken for an agreed transaction plan. Label unresolved elements clearly and date every version, so nobody negotiates from a stale deal structure diagram.
A second pitfall is letting the diagram drift from the underlying documents. Legal and tax teams sometimes revise the SPA, escrow agreement or financing term sheet without feeding those changes back into the deal structure diagram, so the visual plan and the contracts fall out of sync. Before signing, reconcile the deal structure diagram against the latest drafts and the findings summarised in our Vietnam M&A due diligence checklist, since diligence often forces structural changes late in the process.
A third pitfall is treating the tax overlay as an afterthought. Vietnam’s withholding tax, capital assignment tax and stamp duty rules interact with the corporate steps shown on the diagram, and a late change in consideration mechanics can quietly invalidate an earlier tax position. Keep the deal structure diagram synchronised with tax advice throughout negotiation, not only at signing, and benchmark each step against current guidance such as the OECD’s overview of cross-border M&A practice.
Worked Example: Structuring a Two-Stage Vietnam Acquisition
Consider a foreign buyer acquiring 100% of a Vietnamese manufacturing company in two stages: an initial 65% tranche at signing, followed by a put/call option over the remaining 35% after two years. The first-stage deal structure diagram should show the buyer’s holding entity, the seller’s residual stake, the escrow mechanism securing warranty claims, and the M&A approval and licence-amendment steps required for the initial tranche.
As the deal progresses, the diagram must evolve. Once due diligence surfaces risks of the kind described in our review of legal red flags that can stop a Vietnam acquisition, the team may add a specific-indemnity box, adjust the escrow percentage, or introduce a holdback tied to a pending licence renewal. Updating the deal structure diagram at each milestone keeps legal, tax and finance aligned, and prevents the second-tranche documentation from being drafted against an outdated plan. A well-maintained deal structure diagram also gives the closing team, and any incoming licence and regulatory due diligence workstream, one consistent reference point through completion.
Conclusion
A strong deal structure diagram is a decision tool, not decoration. It translates legal form, tax consequences and financing mechanics into one testable transaction plan. When maintained throughout the deal, it reduces drafting inconsistencies, exposes missing approvals and gives the closing team a reliable blueprint. IVLF can assist investors and transaction teams in preparing and validating Vietnam M&A structure diagrams.
Frequently Asked Questions
What should a deal structure diagram include for a Vietnam M&A transaction?
A complete deal structure diagram should show every transacting entity and its jurisdiction, current and proposed ownership percentages, the consideration and financing flow, the tax steps triggered at each transfer, the regulatory approvals and licences required, and the sequence of closing conditions.
Who should prepare the deal structure diagram?
The diagram is normally drafted jointly by the deal’s legal, tax and financial advisers, then validated by the buyer and seller’s internal teams. A single owner should maintain version control so updates from each workstream are reflected consistently.
How often should the diagram be updated?
It should be revisited at every material milestone: after signing the term sheet, after due diligence findings are confirmed, after financing terms are finalised, and immediately before closing, so the diagram never falls behind the transaction documents.
Can a deal structure diagram reveal tax inefficiencies before signing?
Yes. Overlaying each transfer step with its tax consequence often exposes avoidable withholding tax, capital assignment tax or stamp duty exposure while the structure can still be adjusted, which is far cheaper than restructuring after signing.
Does IVLF help prepare deal structure diagrams for Vietnam transactions?
Yes. IVLF’s M&A advisory Vietnam team prepares and validates legal, tax and financial structure diagrams for buyers, sellers and investors, and coordinates the diagram with due diligence, drafting and closing workstreams.
