Is condo developer going to assess us for newly built amenities?

We own in a very large complex. It is not built out yet. The builder is one of the nation's largest. We have some very expensive pools, golf courses, walking trails etc. Yet we keep adding more and more some are in the multi-million dollar bracket. When we question things we are told that the developer gave them to our condo association. It seems impossible that the developer be that nice a corporation as to give away millions of dollars in amenities. My question is can the developer be keeping a running tab and if so can we be assesed to repay it when the complex is finished.
