Name one company in the USA which didn't take outside funding and exited for more than 30mm usd?
National Instruments is an amazing company...I was fortunate to get to use their products on some projects as a teenager.
They IPO'd in 1995, btw.
In SAS's case they pay up to $70,000 as a bonus, in Canada anyway: http://www.eluta.ca/top-employer-sas-canada. Averages seem to range from $9000 to $32,000 (http://www.glassdoor.com/Bonuses/SAS-Institute-Bonuses-E3807...)
