Explanation:

The primary goal of a corporation's board of directors and upper management is to maximize the wealth of the corporation's shareholders. And if you really want to determine how good or bad they are performing, you should compare to how other hypothetical managers or directors would act and perform. E.g. it is very difficult for a company like Google, Disney or Apple to lose money, even if their top managers aren't that brilliant, but what shareholders will seek is that their performance excel the performance of other potential managers. That is why it is really difficult to replace great CEOs like Bob Iger or Steve Jobs.
