Sorry for the late response, just got your message.
PLEASE CORRECT ME IF I'M WRONG, THIS IS WHAT I'VE OBSERVED:
That's an odd assumption on corp values.
If they retain money, have a good, healthy stock, and lots of upgrades and a history of profit, they get high corp values.
>IPO'ing is kind'a dangerous as there are numerous dodged taxes. It happens in real life, and is kinda painful. However, if you sell 5% (check the portfolio targets as to make it 95%) then you recieve more money. How? It pays property taxes. State corps will not pay full profit, and just buy more stuff with it.
>IPO'ing can be dangerous, but if you retain a minimum 20% and it becomes enterprise, it can do a substantial amount more upgrades.
>By selling on the local market, this happens; qua 170 supplies>qua 200 upgraded corp>qua 273 supplies.
Then, you make them sell to eachother and thus qua 273
24% is the max, I try to get the country its in 23%, my second enterprize 23%, and the controlling enterprize 24%, reduces the chance of someone screwing it up...
