Evolution of the Swiss Audit Market

The chart depicts the evolution of active limited companies (AG, SA) and limited liability companies (GmbH, Sàrl) and shows how many of them have a statutory auditor. The decline is strongly related to the possibility of an opting-out for companies with up to ten employees which was introduced in 2008. At the same time, the number of new company registrations has increased significantly over the last years, thus reducing the audit rate for limited companies and limited liability companies from around 64% in 2005 to currently less than 20%.
