Profit transfers seem to inspire some peculiar myths.
A profitable corp distributes some cash if the profit transfer is >0%, and if it has more cash than loans. The corp doesn't have to wait until it has 200b cash to distribute some cash.
A profitable corp that has 50b in net cash will distribute some cash automatically, regardless of the profit transfer setting.
From the documentation on Managing Corporations:
"19. Profit payments
Corporations with large amounts of cash are forced to transfer some of the cash to their owners. These transfers begin at net cash levels of around 50 B and amount to 2 B per game month and they are increased if net cash is at 100B and 300B levels."
However, I have not seen profitable corps with a net cash of 50b make regular monthly payments of 2b. But they periodically pay something, usually less than 2b.
I have not seen profitable corps with a net cash of 250b automatically pay 50b.
