Such CEOs underperforming compared to their prior performance as well as the performance of their peers

The compensation of such CEOs rose significantly on attainment of the superstar status but their performance declined

Such CEOs spent a disproportionate amount of time doing other activities such as attending public and private events as well as writing books

All the above
