The second-biggest automaker in America is getting ready for a changing of the guard: according to Bloomberg, Ford is preparing to name its Chief Operating Officer Mark Fields as its next CEO. Under the reported plan, current CEO Alan Mulally would step down before the end of the year despite Ford claiming late last year that he would stay on as CEO through 2014. It also comes after several months of rumors and speculation that Mulally was Microsofts top choice to replace outgoing CEO Steve Ballmer. Shortly after Ford claimed that Mulally, a 25-year Ford veteran, was staying put, Microsoft announced that longtime employee Satya Nadella was taking over.
