Newsletter 1/21: Modernisation of Swiss Company Law
After a project lasting ten years, the extensive revision to company law is (finally) being implemented. The provisions relating to gender quotas and transparency rules for commodity companies (both with a transition period) already entered into force on 1 January 2021; the main part will enter into force in 2022. Key features of the new law are the introduction of new principles on corporate governance such as those relating to gender quotas and transparency regulations for commodity companies. The revision also includes a variety of simplified procedures and clarifications, in particular more flexibility for changes to share capital, the permissibility of interim dividends and purely virtual general meetings. Read our newsletter to find out what opportunities the revised law will offer, but also what duties will require action.
