The 2024 Switzerland Spencer Stuart Board Index is a survey of the 20 largest public companies with a premium listing on the Swiss Market Index, as of May 31 2024.
The companies in the SMI represent a significant portion of the Swiss equity market, accounting for approximately 80% of market capitalisation.
Our analysis is based on a combination of publicly available sources, such as company annual reports, websites, announcements, and articles of association, as well as proxy statements where accessible. Metrics on board size, committee structure, board and committee meetings, and director remuneration are derived from the most recently available annual reports covering the 2023 and 2024 financial years.
Board composition indicators — including female and foreign representation, independence, tenure, age, and the number of newly appointed and first-time directors — are assessed as of May 31, 2024.
Reflecting the updated composition of the 20 largest companies on the SMI for the period under review, our survey this year includes Kuehne + Nagel, which has replaced Credit Suisse Group as a constituent.
