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....

Same thing is happening in all my countries (7) and my ceo's (5).

Not to mention the slashing of product price in many many high profit companies like assets maintenance and defensive weapons maintenance, most of my corps in these areas have gone from a 1.1-1.2 billion a month profit to 100 to 200 million a month.

I sure wish people would stop messing with the things that aren't broken and use their time more efficiently, like creating insidious war rules that don't benefit anyone but the gamemaster. Oh, wait....
