British philanthropist and investor Lynn Forester de Rothschild has sold her family's entire 26.9% stake in The Economist to Canadian billionaire Stephen Smith and his family holding company Axios. This is the biggest ownership shake-up for the publication in a decade. As part of the deal, Forester and her family will give up their 20% ownership of voting shares, which is the maximum cap for any single owner in the business. The financial terms were not disclosed, but the family's full stake is expected to be valued at up to £400 million or $537 million.
