Raising money from IPO.

Just a quick question regarding going public.

I know you can raise around 20% of your current value by doing an IPO. Now, I liquidated my subsidy a few months back and restarted with around $112 million

This is my current balance sheet at the moment:

Equity 17,719,162 AS$

Shareholders equity 112,506,868 AS$

Loan. 0 AS$

How much money can I raise from an IPO? Roughly?

Thanks

Saad
