Eugene Isenberg, Nabors Industries
In 2008, shares of the oil and gas drilling company plummeted 51%, although the company's stock has outperformed industry rivals over the last 12 months.
Isenberg's total compensation was driven mostly by a $58.7 million bonus, which was calculated based on a percentage of the company's cash flow. Over the years, this formula has resulted in $625 million in "aggregate bonuses" for Isenberg.
A Nabors spokesman said Isenberg recently renegotiated his contract and that his bonus formula is now based less on company cash flow.
