Excessive corp cash

Just a question about corporation cash levels. Once a corporation hits about $90B in available cash, I see that there are automatic transfers out of the corporation. Sometimes in the amount of $2B. Where does it go? I checked through my cash transactions of my country, line by line, as far as I could. I do not see any cash transfers back. Just the regular profit payments, tax, dividends, etc.
But those cash transfers OUT of corps seem to disappear.. my country is bleeding funds.. even though my country budget is always running a surplus. Something is VERY wrong....

Ok, I noticed some corps do exceed $90B, so those funds are probably not evaporating (I hope). I raised the profit transfer to try and reclaim those funds; they are just sitting there unused.

Almost reminds me of American wealth; just sits in accounts of the wealthy.

Mabye some people within hide the money?

I hope it is clear now.
