Corporate Governance and Code of Conduct

Even although it is not a listed company, CSS adheres to corporate governance guidelines and principles. These determine the system of rules regarding organisation, actions and transparency through which the company is controlled and directed. In doing so, it is guided by the “Swiss Code of Best Practice for Corporate Governance” issued by economiesuisse, the umbrella organisation for the Swiss business sector.

Code of Conduct


CSS was founded in 1899 as a self-help organisation under the name Christlich Soziale Schweiz (Christian Social Switzerland, CSS), in response to Pope Leo XIII's "Rerum Novarum" encyclical, which addressed the emergence of a proletariat from the labouring classes. At the time, CSS viewed its objectives as specifically Christian. There has been little change in its actual purpose in the intervening years: our healthcare system is still based on solidarity, one expression of which is the uniform premium. Regardless of their income, all insured persons have access to healthcare services. In today's world, the values on which CSS Insurance is built, such as the principles of solidarity and fairness, are perceived as separate from basic Christian precepts.
