Guide pratique

Change country

In many situations of an M&A deal, the purchaser and the seller can have conflicting interests as regards whether to structure the transaction as a sale of shares of the targeted business or as a sale of the business itself. Generally, purchasers prefer asset deals whereas sellers prefer share deals. However, each M&A transaction is unique, and the choice of the structure is always agreed to on a case by case basis.

This online guide highlights the main differences between the two structures in various countries around the globe. Our legal experts provide an overview of the main features of share deal or asset deal structures, a summary of the processes to either transfer shares or assets, and the principal transfer taxes relating thereto. This online guide, which is organised in a Q&A format, is thus designed to help international companies or investors who are looking to sell or purchase businesses in foreign countries and who need a brief overview of the local specificities as regards share deals versus asset deals.

What are the main features of a share transfer agreement in Hong Kong?

The share purchase agreement is a bespoke document, tailored to align with the agreed deal parameters. However, the main features of a share purchase agreement documenting the terms and conditions of the transfer of shares of a Hong Kong private company limited by shares are set out below.

  • Corporate authorisations - The transfer is subject to approval by the board of directors of the target company whose shares are being transferred. In case the parties are corporate entities, appropriate internal authorisations (board resolutions or powers of attorney) must be obtained to approve the transaction and the execution of the share purchase agreement.
  • Continuity of contracts – Existing contracts entered into between the target entity and third parties do not need to be assigned or novated. If such contracts contain change of control provisions, relevant notification and/or authorisations requirements must be complied with before closing.
  • Signing and completion – The share transfer transaction may be structured either with simultaneous signing and completion, or with split signing and completion (for instance in the case of earn out mechanism or where regulatory approvals are required).
  • Ancillary changes – The share purchase agreement addresses any other changes that must take place simultaneously to the completion of the share transfer, such as changes of directors, company secretary, registered office, signatories authorised to operate the company’s bank accounts, etc.
  • Warranties and indemnities – It is customary for the share purchase agreement to contain warranties and indemnities, which are usually limited in an intragroup restructure scenario, and extensive and more heavily negotiated where the parties are unrelated.
  • Restrictive covenants – In case the parties negotiate restrictive covenants placed on the seller, such covenants must be carefully drafted and narrowly tailored to maximise enforceability.
  • Disclosure letter – It is market practice for the seller to deliver a letter disclosing any limitation, qualifications or exceptions to the warranties given under the share purchase agreement to the seller at closing, thus limiting the seller’s liability.
  • Stamp duty – It is customary for the stamp duty on the share transfer to be borne in equal proportions by each of the buyer and the seller, but the share purchase agreement should include a clause specifying the apportionment mechanism.
  • Signing formality – If the share transfer is not supported by consideration, the share purchase agreement must be executed as a deed.

What are the main features of an asset transfer agreement in Hong Kong?

An asset transfer agreement allows the buyer to selectively acquire specific assets and liabilities. Although the agreement is tailored to align with the deal parameters, its key features are set out below.

  • Precise asset and liabilities identification – The agreement clearly identifies and lists the assets subject to the transfer and any specific liabilities being transferred.
  • Corporate authorisations – The articles of association and other internal organisational documents of the parties should be reviewed to confirm whether authorisations must be obtained from their respective board of directors and shareholders.
  • Warranties and indemnities – The asset transfer agreement can contain specific warranties and indemnities, which are tailored to the type of assets transferred. There are typically no or limited warranties and indemnities in an intragroup restructure scenario, whereas their scope is usually wider where the parties are unrelated.
  • Disclosure letter – It is market practice for the seller to deliver a letter disclosing any limitation, qualifications or exceptions to the warranties given under the asset transfer agreement to the seller at closing, thus limiting the seller’s liability.
  • Documents deliverable – The asset transfer agreement typically contains a list of documents deliverable by the parties at completion, in particular to effect the transfer of specific types of assets (application to register transfer of intellectual property rights, delivery of title deeds for real estate assets, etc.).
  • Signing formality – If the asset transfer is not supported by consideration, the asset transfer agreement must be executed as a deed.

In case the parties are corporate entities, appropriate internal authorisations (board resolutions or powers of attorney) must be obtained to approve the transaction and execution of the share purchase agreement.
