Sale and Purchase Agreements in Hong Kong: Key Terms and Negotiation Guide

Introduction

A sale and purchase agreement (SPA) is the definitive legal document governing the acquisition of a business, company, or assets in Hong Kong. Whether the transaction involves a private company acquisition, an asset purchase, or a cross-border deal with Hong Kong elements, the SPA is the central document that defines the deal terms, allocates risk between buyer and seller, and establishes the legal framework for completion.

Structure of a Typical SPA

A Hong Kong SPA typically covers the following key areas:

• Definitions and interpretation
• Sale and purchase of shares or assets
• Purchase price and adjustment mechanisms
• Conditions precedent to completion
• Completion obligations
• Representations and warranties
• Indemnities
• Restrictive covenants (post-completion)
• General provisions (governing law, dispute resolution, notices)

Purchase Price and Adjustment Mechanisms

The purchase price in an SPA may be expressed as a fixed amount or subject to adjustment. Common price adjustment mechanisms include:

Locked Box

Under a locked box structure, the purchase price is fixed by reference to a historical balance sheet (the "locked box date"). Between the locked box date and completion, the seller is restricted from "leaking" value out of the business. This mechanism provides certainty for the seller and eliminates post-completion disputes about valuation, but requires the buyer to accept the locked box balance sheet.

Completion Accounts

Under a completion accounts mechanism, the purchase price is adjusted after completion by reference to the actual financial position of the business at the completion date. Net asset or working capital positions are compared against an agreed target, and the purchase price is adjusted accordingly. This approach is more complex and can lead to post-completion disputes about the preparation of accounts.

Earn-Out

Earn-out provisions link part of the purchase price to the future performance of the target business. They are common in transactions where there is disagreement about current valuation, or where the seller's ongoing management is important to post-completion performance. Earn-outs require careful drafting of financial metrics and dispute resolution procedures.

Representations and Warranties

Representations and warranties are statements of fact about the business being sold. They are central to the risk allocation in any SPA. Common warranty areas include:

• The authority and capacity of the seller to enter into the transaction
• The accuracy of the financial statements
• Ownership of assets and absence of encumbrances
• Material contracts and customer relationships
• Employment matters and key persons
• Intellectual property ownership
• Litigation and regulatory matters
• Tax compliance
• Real property

Warranty disclosure is a critical process: sellers disclose facts and circumstances that qualify the warranties in a disclosure letter, which limits the seller's exposure for matters disclosed.

Warranty and Indemnity Insurance

Warranty and indemnity (W&I) insurance has become a standard feature of larger Hong Kong M&A transactions. It allows buyers to make warranty claims against an insurer rather than (or in addition to) the seller, improving deal certainty for sellers and facilitating clean exits. W&I insurance also features in private equity exits where the seller wishes to distribute sale proceeds to investors without retaining a warranty escrow.

Conditions Precedent

Large transactions typically require the satisfaction of conditions before completion can occur, such as:

• Regulatory approvals (e.g., SFC, competition authority)
• Shareholder approvals
• Third-party consents (e.g., lenders, counterparties to material contracts)
• No material adverse change

The parties' respective obligations to use "best endeavours" or "commercially reasonable endeavours" to satisfy conditions, and the consequences of conditions not being satisfied by a long-stop date, require careful negotiation.

Completion Mechanics

Completion specifies what must happen simultaneously for the transaction to be legally consummated: delivery of executed documents, payment of the purchase price, delivery of share certificates and stock transfer forms (for share purchases), board resolutions, and regulatory filings.

Governing Law and Dispute Resolution

Hong Kong-governed SPAs commonly include arbitration clauses (HKIAC being the most popular arbitral institution) or submission to the jurisdiction of the Hong Kong courts. Choice of law and dispute resolution are particularly important in cross-border transactions where the parties have different jurisdictional connections.
