Not sure its that much.
You could use as a formula that they are owed their base salaries and then some. But most are sales and they are highly leveraged in terms of compensation.
There are some stories I could confirm... ;-)
I even had one deal taken away from me because I was well in to my bonus and it would have meant an extra 75K in bonus on top of what i was making.
