Many subsidaries?

Okay, so I opened 2 Subsidaries from my holding company in fornebu. However, I noticed a few companies have up to 6 or 7 subsidiaries from there main holding company. How is this so if they only start off with 10 million dollars and it costs 3 million to start a new subsidiary?

You can transfer money through "Asset Management" to your holding and your holding is able to make profit by dividendes of stocks.

Or their holding is an airline itself;)
