Which of the following would be a violation of management's fiduciary responsibility to its shareholders? a. Management undertakes a project that turns out to be a loser, even though they had concluded it was a positive-NPV project before they undertook it. b. In its efforts to expand internationally, which it believes will enable it to increase its profitability, a cable company lays cables throughout a third world country, only to have its underground assets expropriated by the government of that country. c. Management agrees to acquire a small firm that is owned by one of its board members and that manufactures a product that is similar to its own product line, basing its decision on that member's NPV analysis of his business. d. All of the above will erode shareholders wealth and are, therefore, violations of management's fiduciary responsibility to its shareholders.
