Warranties and indemnities are the risk allocation heart of a private M&A transaction in Hong Kong. Warranties are the seller’s contractual statements about the target. Indemnities are the seller’s promises to pay for specific identified risks. Together with caps, baskets, survival periods, knowledge qualifiers, the disclosure letter, and increasingly W&I insurance, they decide who bears the loss when reality diverges from what the buyer was told at signing.
This guide sets out how warranty packages actually work in a Hong Kong SPA: the difference between warranties and indemnities, the numbers behind caps and baskets, the time limits that survive closing, how the Misrepresentation Ordinance (Cap. 284) shapes non-reliance drafting, and what the W&I insurance market in Hong Kong currently looks like. For the full SPA structure see the Share Purchase Agreement guide. For the wider deal framework see the M&A in Hong Kong guide and the Acquisitions practice. For pre-signing risk review, see legal and tax due diligence.

Why warranties and indemnities matter in Hong Kong M&A
In a Hong Kong private M&A, the buyer buys a company (or a business) on the basis of what the seller tells it during the process. Financial statements, DD responses, management representations, data room contents. Warranties and indemnities turn those statements into legally enforceable allocations of risk. If reality diverges from what the buyer was told at signing, the warranty and indemnity regime decides how much the buyer can recover, from whom, within what time frame, and subject to what qualifications.
The regime sits alongside the legal and tax due diligence workstream. What DD surfaces before signing shapes the warranty package (specific warranties, indemnities, price adjustments, escrow, or W&I insurance retention areas). What DD misses is what the buyer will rely on the warranty regime to recover.
Warranties versus indemnities: the two remedies
Warranties and indemnities coexist in the same SPA and often overlap on the facts. But they are structurally different remedies with different tests, different measures of loss, and different practical uses.
Nature. Contractual statements of fact about the target at signing (and often at closing).
Remedy. Damages for breach of contract. Buyer must prove loss caused by the breach, subject to remoteness and mitigation rules.
Measure. Puts buyer in the position it would have been in had the warranty been true (diminution in value).
Qualifiers. Subject to the disclosure letter, knowledge qualifiers, materiality thresholds, caps, baskets and survival periods.
Nature. Contractual promise to pay for a defined loss on a HK$ for HK$ basis.
Remedy. Direct payment. No requirement to prove diminution in value. No mitigation or remoteness constraints unless the SPA imports them.
Measure. The actual loss, cost, liability or Third-party claim covered by the indemnity wording.
Uses. Known DD issues, tax (via a tax deed or tax covenant), pending litigation, environmental exposure, IP claims, specific regulatory risks.
Business warranties, tax warranties, fundamental warranties
Warranty packages in Hong Kong SPAs commonly split into three categories:
- Business warranties. Trading, accounts, contracts, employment, IP, litigation, real property, regulatory. The bulk of the warranty schedule.
- Tax warranties and tax deed. Historical tax filings, contingent tax liabilities, transfer pricing, section 45 stamp duty relief claims (see the stamp duty guide), FSIE compliance, treaty positions. Backed by an indemnity-style tax deed on identified pre-completion exposure.
- Fundamental warranties. Seller’s title to the shares, capacity, authority, no consents required. Non-negotiable core warranties, typically at 100% cap.
When to use an indemnity rather than a warranty
Indemnities are the buyer’s tool where DD has surfaced a specific, identified issue: an open IRD assessment, a pending litigation claim, a licence non-compliance, an environmental exposure. The buyer wants a HK$ for HK$ recovery mechanism, not a warranty that may be defeated by disclosure or diluted by qualifiers. Tax deeds are the archetypal indemnity: they provide direct recovery for pre-completion tax liabilities without engaging the warranty caps.
Drafting a buy-side warranty package or reviewing a seller’s disclosure schedules? A 30-minute confidential call is enough to identify the top negotiating points on caps, baskets, and knowledge qualifiers.
Caps, baskets and de minimis: the numbers
The commercial contours of the warranty package are set by three quantitative levers. All three are negotiated line by line and vary with deal size, target sector, seller identity (PE fund vs founder), and DD findings.
Commonly 20% to 100% of price
Business warranties typically capped at 20 to 30% of consideration on strategic deals, higher on PE exits with limited seller recourse. Fundamental warranties (title to shares, authority, capacity) commonly at 100%.
Category-specific limits
Sub-caps often applied to tax indemnity (matching estimated tax exposure), IP warranties, or a specific known risk carved out of the general cap.
Tipping vs excess
Aggregate claims must exceed a threshold (commonly 0.5 to 1% of consideration) before recovery. Tipping basket = full aggregate recoverable. Excess basket = only amount above threshold.
Individual claim floor
Individual claims below a threshold (commonly 0.05 to 0.1% of consideration) do not count towards the basket. Prevents nuisance claims and administrative burden.
These ranges are market observations from Hong Kong private M&A practice. Exact positions depend on the transaction, and W&I insurance availability can shift them materially, particularly on PE-backed exits where the seller often walks away with a nominal 1 dollar cap and the buyer relies on insurance for warranty recovery.
Survival periods: how long claims can be brought
Warranty survival periods define the window within which the buyer must serve a claim notice. Once the period expires, the warranty is unenforceable regardless of the underlying breach.
18 to 24 months
Business warranties typically survive one to two audit cycles post-closing. Longer periods increase seller exposure and price accordingly.
6 or 10 years
Matched to the section 60 IRO assessment window: 6 years generally, 10 years for fraud or wilful evasion. Enables the buyer to recover if IRD reopens a prior year.
Indefinite or long-tail
Title to shares, capacity, authority, and existence commonly survive indefinitely or for the applicable limitation period under the Limitation Ordinance (Cap. 347).
Claim within survival + notice window
Buyer must serve a claim notice before the survival period expires. Standstill or notice-and-cure periods commonly follow before proceedings can be issued.
Knowledge qualifiers, materiality and fair disclosure
Sellers negotiate to scope warranties with knowledge qualifiers (“to the seller’s knowledge”, “so far as the seller is aware”) and materiality thresholds. The buyer’s push-back is to name whose knowledge counts (usually named senior executives), to require reasonable enquiry, and to remove materiality qualifiers from warranties that are later re-subject to caps and baskets.
The buyer’s other lever is fair disclosure. The SPA should provide that only matters fairly disclosed in the disclosure letter carve out the warranties, meaning the disclosure must be sufficient to inform a reasonable buyer of the nature and impact of the disclosed matter. Wide “everything in the data room” disclosures are the seller’s opening position; the buyer negotiates towards specific numbered disclosures against individual warranties.
The disclosure letter
The disclosure letter is the seller’s document. It typically contains two layers:
- General disclosures. Matters of public record (Companies Registry, Land Registry, Court filings, IPD searches) and matters in the data room, framed as disclosed against all warranties. Buyers push to narrow the general disclosures to specific matters.
- Specific disclosures. Numbered disclosures cross-referenced to specific warranties. The buyer accepts these on the fair disclosure standard.
Negotiating the disclosure letter is where DD findings translate into risk allocation. What the seller discloses, the buyer accepts as excluded from warranty recovery. What is not disclosed remains a warranty claim if it later materialises. This is why the buyer’s counsel must review disclosure schedules against the DD report line by line.
Sandbagging clauses shape the position further. A pro-sandbagging clause allows the buyer to claim on a warranty even where DD showed the buyer knew the warranty was untrue at signing. An anti-sandbagging clause bars such claims. Absent express drafting, Hong Kong courts follow common law and the outcome is contested.
Negotiating the disclosure letter is where value is lost or preserved. Slotine drafts and defends disclosure schedules on both buy-side and sell-side mandates, coordinating with the DD workstream.
Misrepresentation Ordinance (Cap. 284) and non-reliance drafting
Hong Kong contract drafting includes a non-reliance clause and an entire agreement clause. Together they push all pre-contractual representations, DD responses, and management statements out of any misrepresentation cause of action and back into the negotiated contractual warranty regime.
The Misrepresentation Ordinance (Cap. 284) governs damages for pre-contract misrepresentation. Section 3(1) reads verbatim: where a person has entered into a contract after a misrepresentation made to him by another party and as a result has suffered loss, the person making the misrepresentation is liable to damages as if the misrepresentation had been made fraudulently, unless he proves he had reasonable grounds to believe and did believe up to the time the contract was made that the facts represented were true.
The buyer’s incentive is therefore strong to litigate under Cap. 284 s. 3 for misrepresentation damages rather than under the SPA warranty regime, because misrepresentation damages bypass the caps, baskets, and survival limits. The seller’s counter is the non-reliance clause, subject to the Cap. 284 s. 4 constraint below.
The buyer confirms it has not relied on any statement, representation, or information other than those expressly set out in the SPA as warranties. The seller correspondingly limits its exposure to the contractual warranty regime with all its qualifiers (disclosure, caps, baskets, survival).
Without the non-reliance clause, the buyer could sue on the same underlying facts under Cap. 284 s. 3 for misrepresentation damages, bypassing the negotiated warranty limits.
A contract term that excludes or restricts liability for pre-contract misrepresentation is of no effect except to the extent it satisfies the reasonableness test in section 3(1) of the Control of Exemption Clauses Ordinance (Cap. 71).
The Hong Kong drafting solution is a carefully worded non-reliance clause supported by an entire agreement clause. Poorly drafted or one-sided exclusions can be struck down as unreasonable.
W&I insurance in the Hong Kong market
Warranty and indemnity insurance covers the buyer for unknown breaches of the warranty package. It has become a standard tool on PE-backed transactions, where the seller wants a clean exit with minimal residual liability, and increasingly on strategic deals where valuation gaps are bridged by an insurance-backed warranty package.
Take-up in Hong Kong is lower than in the United Kingdom, the United States, or continental Europe, but the market has grown steadily. Major international brokers place W&I on Hong Kong deals: Marsh, Aon, WTW, Lockton, Howden. Underwriting capacity is sourced primarily from London and Singapore markets, with local underwriters in some cases.
What W&I insurance typically covers
- Breaches of business warranties (with specific carve-outs for known DD issues, transfer pricing, secondary tax exposure, and prospective tax risks).
- Tax deed exposure (via a separate tax policy or an extension of the W&I policy).
- Specific indemnities in some cases (a specific contingency insurance policy).
Retention and premium
Policies carry a retention (an amount the buyer bears before insurance responds) typically expressed as a percentage of enterprise value. Premium is usually a low single-digit percentage of the insured limit, with rates varying by deal profile, sector, and DD quality. These numbers are negotiated with the broker and underwriter deal by deal.
Buy-side vs sell-side policies
Buy-side policies are the market standard: taken out by the buyer, they pay the buyer directly for covered warranty breaches. The seller’s SPA warranty liability can then be capped at a nominal amount (often HK$1 or 1 US dollar), which is what makes W&I insurance attractive on PE exits. Sell-side policies, taken out by the seller, are rarer and reimburse the seller for amounts paid out under SPA warranty claims.
Five common W&I mistakes in Hong Kong M&A
Buyer accepts a sweeping “everything in the data room is disclosed” wording, losing the ability to challenge unfairly disclosed matters. Insist on the fair disclosure standard and specific disclosure schedules.
“To the seller’s knowledge” without defining whose knowledge and whether it includes constructive knowledge produces uncertainty. Name the relevant individuals and specify actual or actual-plus-reasonable-enquiry knowledge.
Setting tax warranty survival at 3 years leaves the buyer exposed to IRD assessment years 4 to 6 (or 7 for wilful evasion). Match tax deed survival to section 60 IRO.
One-sided or blanket exclusions can fail the Cap. 71 reasonableness test that Cap. 284 s. 4 imports. A carefully worded non-reliance and entire agreement combination is essential.
Approaching brokers only late in negotiation limits the buyer’s ability to push seller liability towards insurance. Engage brokers alongside DD to shape the warranty package.

How Slotine advises on warranties and indemnities
Slotine advises buy-side, sell-side and PE clients on the full warranty and indemnity workstream on Hong Kong and cross-border M&A:
- Pre-signing: calibrate the warranty package to DD findings, target sector, and risk appetite. Model caps, baskets, de minimis and survival positions.
- Drafting: draft business and tax warranty schedules, tax deed, specific indemnities, non-reliance and entire agreement clauses tuned to Cap. 284 constraints.
- Disclosure: draft or defend the disclosure letter, translate DD findings into fair specific disclosures, negotiate general disclosure scope.
- W&I insurance: coordinate with brokers (Marsh, Aon, WTW, Lockton, Howden), review underwriter mark-ups, negotiate carve-outs and retention.
- Post-completion: monitor warranty survival windows, prepare and defend warranty claim notices, coordinate with W&I policy claims teams.
- Cross-border: coordinate with international counsel via Legalmondo and Ursusnetwork where the seller or buyer is domiciled in France, Belgium, Switzerland, Luxembourg, the United Kingdom, the United States, or Portuguese-speaking jurisdictions.
