Ann: Notice of Annual General Meeting/Proxy Form, page-2

I don't understand the numbers in Section 6.5, part Q

if the milestones attaching to the Incentive Performance Rights issued to
the Related Parties are met and the Incentive Performance Rights are
converted, a total of 7,500,000 Shares would be issued. This will increase
the number of Shares on issue from 2,144,482,373 (being the total number
of Shares on issue as at the date of this Notice) to 2,141,482,373 (assuming
that no Shares are issued and no convertible securities vest or are
exercised) with the effect that the shareholding of existing Shareholders
would be diluted by an aggregate of 0.35%, comprising 0.14% by Mr
Stephen Quantrill, 0.07% by Ms Anna Neuling, 0.07% by Mr Keith Liddell
and 0.07% by Mr David Chapman

How is 2,141,482,373 an increase from 2,144,482,373?

Someone please explain it to me, as I am bemused.

Disclosure: Formally held and looking to buy again at a price target, but need to now digest the performance rights... still reading!
