i dont remember what the thread was called but there was a really good one a few weeks ago asking a similar question and a few pros responded as to how their (and most) sponsorships work. if someone can find it that will prob answer your question pretty well.
wtf do you care? are you applying for this profession? would it sway your opinions on certain skiers? will you go to university if the amount isnt within your expectaions? are you an accountant workin for the IRS??
No i was not and i was just curious to see because its not something that i think alot of people know. However if you did go into the industry im sure you would want all your dedication and fun to pay off kinda even though the main thing is to be having fun
