Base salary 60-80k
Bonuses, depends on the year. 3 out of 4 years will be inaccurate or bogus data so you won't make much money anyways. But on the 4th year you could possibly make what they call "to plan". They will use word like "modifier" to further confuse the math.
Bottom line, take the job for the base salary. Any "bonus" at all is just gravy. Allergan is only about paying their CEO, Presidents and Vice Presidents. Everyone else can suck eggs.
