What does $1 buy?

A list of a few top CEOs that are only making $1 a year in salary:  

Steve Jobs - Apple

Terry Semel - Yahoo CEO

Eric Schmidt - Google

John Mackey - Whole Foods

Edward Liddy - AIG

Considering the other 3 components of Executive Compensation, What kind of statement is really being made?  Is there a way to qualify its success? If nothing else it gets analyst talking.

The minimal salary is definitely not stating that the CEO is "taking one for the team."  I think it is more a component to instill confidence into a company. There are many reasons confidence is necessary, either to raise stock in an already profitable company such as Google, or in AIG's place to help from folding completely.

The other components of executive compensation will ALWAYS make up for the $1 salary. How does it look to the average person when they see "CEO has $1 salary" in the newspaper?  Do not be fooled, bonuses, stocks, and options are more than plenty for the CEO.  That's not even to mention the perks and benefits included in their high profile position.  I wonder if they actually even take the $1. It would make for an interesting pay stub at least.
