The UK based magazine The Economist will maintain its independence after a sale of 50% shares is completed to Exor or some other company. This is because the shares sold are "B" shares. "A" shares and trustee shares will be retained so that the independence of the magazine is not affected. The Economist has increased its circulation to 1.6 million in 2015 from about 1 million in 2006. It reaches a highly educated and upper class audience. The magazine has a unique culture in which journalists debate editorial direction and writers also do editing, with no writer's names mentioned for its short Time magazine type coverage of international topics. It also has a Intelligence and Statistical unit to provide more advanced coverage on some topics such as finance and policy.
