Richard Zannino, the chief executive of Dow Jones, prepared the way on Monday for job cuts at the company after its $5.2bn acquisition by Rupert Murdoch’s News Corp. In a letter to employees of Dow Jones, publisher of the Wall Street Journal, Mr Zannino said the main goal of News Corp’s $5bn acquisition was to “increase profits by strengthening” products and brands, “not by slashing costs”. However, he added, “there will be some changes”, and “where job cuts are unavoidable, we will communicate that as soon as practical”. The letter follows last week’s regulatory filings which begin a countdown to a shareholder vote on the merger.
