Abstract This paper analyses ownership and control structures of Dutch listed companies. Legislation, effective since 1992, mandates all shareholders with holdings of 5% or more in Dutch companies to disclose their holdings. Our analysis shows that the average ownership stakes of the largest and the three largest shareholders are 27% and 41%, respectively. The average ownership stakes of banks, insurance companies, and other financial institutions are relatively low. We observe that voting rights are more concentrated than ownership rights; the use of a supervisory board representing interests of different stakeholders is ubiquitous; and listed companies use different forms of anti‐takeover defence measures.
