Cash transfer to corporations

I have noticed that several months in a row my corporation are transferring money. I do not see where, no report.
I have no corporation that is running on minus or debt, so where are the money going and why?

Which way is the money going, the title and post conflict.

If a corp reaches a low level of cash, say by buying a load of supplies in one go, then the country/ent will send it money. Low level seems about 15 - 20B. Looking at the graph of cash will show you the cash boost. Also the country finance page will say a minus figure next to automatic transfers.

If the corps has loads of cash it will every now and then pay some off to the country/share holders as a dividend. You will see this again from the graphs and the country/ent finance page showing a positive number for automatic cash transfers. High level for state or regular private corps is about 60B. Publics are far higher and work differently. No transfering cash to them.

You need to wait a game month to see the transactions in the graphs.

It is with minus, and i play ceo without a country.
The funny thing is that i have checked to see if any on my private corps need money. It seems they don't. So now i get loans to pay something hidden.

But what is the actual level of their cash before this transfer takes place?

As Crafty says, it is done automatically if cash reaches something below 20.

You and I would not consider it 'necessary' yet, but the game does.

Oh, btw.: automatic upgrading has this sideeffect. It wouldn't by any chance be corps that have been set to automatic upgrade, but hasn't fully upgraded yet?

Now it has stopped, not sure where the money goes, probably as you said on corps with low budget.
In this period i do not have set the automatic upgrade.
Probably it was split between corps with low level of cash (i have found a spike in a graph from one month to other of 15B).
Thank you for help!
