As others have said, there are 40000-ish employees almost all of whom will have some sort of bonus provision in their compensation. That doesn't mean every year they get one, it doesn't mean everyone gets a big one. There will be a handfull of big swingers who get or expect tens of millions, but the vast majority of folks in an investment bank would get a bonus in the thousands or tens of thousands. It's typically anywhere from 20% of base to a couple of times base depending on how well the firm did as a whole, how much your team/division contributed to that and how good your own appraisal/performance was.
