Great in theory Ultralights, but those big American corporate collapses (e.g. enron, mci worldcom) showed that fat bonuses related to the share price don't really work as all that happens is the fat-cats lie (in the upward direction of course!) about the bottom line, share price goes up, everyone happy, fat-cats sell bonus shares before inevitable collapse, transfer assets to wife and kids and spend five years in court saying they "are just the CEO, we don't have any knowledge of accounting..." before wearing oxygen masks in the courtroom and claiming they have only "months to live"...
