Enterprise corp. funds

In my enterprise the majority of corporations hold roughly 50Bn each, given that the minimum is 30Bn I try and reduce their cash stores accordingly. The problem being this works, I pay off my debt, but by the next login the corporations have somehow reclaimed their original funds and i'm left in debt. Any ideas why this happens?

You skimmed them too close. Try reducing their funds to no less than $40B.

41B seems to work for my enterprise. Just make sure you add to bring any losses back up to 41.

I tend to do 38 and raise to 38
