Publicly traded companies are required by law to reveal the specific reasons for board members' departures if they leave because of disagreements about corporate decisions or concerns about the future direction of the company. Ford said that was not the case with either of these men. Their resignations come just one week after Ford's long-serving chief financial officer, Don Leclair, resigned amid what sources characterized as 'philosophical disagreements' about Ford's financial strategy. The company's stock price also fell below $2 a share recently and remains below $2.50. Bond, who is chairman of wireless giant Vodafone Group Plc, was one of a group of British executives tapped by Prime Minister Gordon Brown to advise him on the economy. Ollila, who chairs both Nokia Oyj and Royal Dutch Shell Plc, has been appointed to a group of business leaders advising the European Union. Ford has no plans to replace either board member. It did not replace Robert Rubin when he resigned from its board in 2006. It still has 11 board members, about average for a corporation of its size. Bond was one of the most trusted and respected financial advisers to the company and its executive chairman, Bill Ford Jr. The automaker said Friday that it has terminated Bond's paid consultancy, but added that he may continue to advise Bill Ford an informal, unpaid basis.
