Profits Interest
  
Who isn't interested in profits? We're interested in profits...do you have any profits for us to be interested in?
You're the head salesperson for a company that makes koala-skin coats. The company, Dundee & Son Down Under Coats, is organized as a partnership. You are neither Dundee nor his son, but you are the best sales person they've ever had.
They want to keep you. To do so, they will give you something special for your years of service and the contribution you've made. They offer you a profits interest. It's a share of the company's profit, even though you never put in any capital. You don't become a partner in the business (Dundee says that's only for him and his son). But you will get a share of any profits the partnership generates.
