dilution

Hi
I read the announcement from BRM yesterday. Just wondering if someone can explain to me the details of this dilutionary effect of the Ferraus offer.

"
Dilutionary impact of FerrAus offer
The Board also notes Wah Nam?s announcement last week in relation to its contemporaneous takeover bid for
FerrAus Limited (?FerrAus?), in which Wah Nam stated that it would waive the 90% acceptance condition relating
to the FerrAus offer if it received acceptances giving it a relevant interest of 50% or more.
Brockman shareholders should be aware that there is the potential for dilution of Brockman shareholders?
interest in the Marillana Project if Wah Nam?s offer for FerrAus is completed. In the event of all shares in both
Brockman and FerrAus being acquired by Wah Nam under the existing offer terms, approximately 4,621,818,732
Wah Nam shares would need to be issued, of which 1,248,146,352 shares or 15% of the total number of
shares on issue within the new identity would be issued to FerrAus shareholders. This share issuance would
result in Brockman shareholders being diluted down to a 39% interest in the Marillana project through their
interest in the combined group, as highlighted in the table "
I don't quite understand the table with the 50% vs 100% headings. I'm sure it's not that complicated, but could someone please break it down for me?
Cheers
