Subscribing to IPO

What are the requirements for a company to qualify to purchase shares in an IPO?

A capital of AS$ 20 Mio.

Ok, thanks a lot.

Quick question on this subject, can you buy your own shares? Like Airline A was put up for IPO. After 2-3 months can Airline A buy airline A's shares ? 

No, you cannot buy your own shares. But the holding for example can.

If I have Parent company A  - makes 2 subsideries (Sub A and B for example). Could Sub A buy Sub B shares? 

Yes
