Industrial foundations are foundations that own companies. Typically, they combine charitable and business goals. Some global companies such as IKEA, Robert Bosch or the Tata Group are foundation-owned, but nowhere are they as numerous as in Denmark. Three of the four largest Danish companies - the pharma company Novo Nordisk, the shipping company A.P. Moller-Maersk, and the Carlsberg brewery - are all foundation-owned. Surprisingly, very little has been written about what industrial foundations are, and how they operate. The Danish Industrial Foundations provides a comprehensive overview. The book covers aspects such as theory, law, taxation, economic importance, company performance, governance and philanthropy. The book is the result of a large collaborative research project, led by the author, on industrial foundations.
