Adsense referrals

Ok, i put a referral ad in my site, (adsense). So if users click it and sign up and make 100$ im gonna have 100$.
The question is, do i have the ability to know if someone signed up for adsense from my ad? (even if they haven't make their first 100$).

thanks.

ps. couldnt find the answer in old threads.

 

Yes, they show you the amount of refferals in your stats. It is labeled as sign-ups.
