Dual listings and secondary listings in Switzerland for companies listed in Asia

Read the PDF edition (2 pages)

A company whose shares are already traded on an Asian exchange may wish to reach European investors, raise its profile in Switzerland or support a local business. A secondary or dual listing on a Swiss exchange can serve these aims, yet the legal consequences differ considerably depending on how the listing is structured.

Primary, dual and secondary listing

In a secondary listing, the shares remain primarily listed on the foreign home exchange, and the Swiss exchange relies largely on the home market's rules and supervision. In a dual listing, the company accepts the full listing regime in both markets. The difference matters, because a full listing brings the complete set of Swiss reporting and disclosure obligations, whereas a secondary listing is designed to keep additional obligations limited.

Admission conditions

Both Swiss exchanges offer simplified admission for issuers with a primary listing on a recognised foreign exchange. The exchange usually requires that the home market's listing standards are equivalent and that information published at home is also made available in Switzerland. The details, including which foreign exchanges are recognised, are set out in the respective rulebooks and should be confirmed with the exchange.

Prospectus and documentation

Admission to trading generally requires a prospectus under the Financial Services Act, but exemptions and simplified procedures may apply to securities already listed abroad, and foreign prospectuses can be recognised under certain conditions. Whether a new document is needed depends on whether new shares are offered publicly in Switzerland.

Which Swiss rules apply

The Swiss rules on disclosure of shareholdings and on public takeovers apply to foreign companies only if their main listing is in Switzerland. A pure secondary listing therefore generally falls outside these regimes, although market abuse rules under the Financial Market Infrastructure Act apply to trading on the Swiss exchange in any case. If trading volume later shifts to Switzerland, the question of where the main listing lies may need to be re-examined.

What pays off in practice

Define the purpose first. Investor reach, visibility and liquidity call for different structures and budgets.
Check equivalence early. The Swiss exchange will want to know how the home market's rules compare.
Plan the information flow. Releases at home must be published in Switzerland at the same time.

Rechtsanwalt/Attorney-at-Law

I am a Swiss attorney-at-law and also admitted as a solicitor in Hong Kong and in England & Wales, with almost 25 years of experience.

Together with my multilingual team, including Chinese, Japanese, Korean, Russian, Ukrainian and French native speakers, I advise companies and their owners from around the world on the full range of banking, corporate, commercial and tax law matters in Switzerland, including international tax planning, fiduciary services, and legal family office services including immigration & relocation or real estate investments. My practice has a particular focus on clients from growth and frontier markets in Greater China, Central Asia and the Caucasus, the rest of Asia, the Middle East, Africa and Latin America, and I equally advise clients from Europe and North America. Through an affiliated Swiss trust company, we also take care of the incorporation and ongoing administration of their companies and other structures, including accounting, tax returns and corporate secretarial services, and I serve as a professional director where required. With the support of a network of first-class cooperation partners, I also implement solutions worldwide.

My approach is to act as a trusted advisor who works directly with decision-makers, on an equal footing: I start from what you want to achieve and shape every structure, contract and tax decision around your commercial goals and how it improves your after-tax return. As “lawyers who make it happen”, my team and I stay involved until your company is set up, your structure is in place and your transaction has closed, and we remain available for any follow-on work that may be required. You benefit from bespoke solutions and personal attention, and sound, friendly and practical advice. We are not the lowest-cost provider in the market, nor do we intend to be; our aim is to deliver well-founded, proper solutions and excellent value for money.
