entitlement

Good afternoon good people. I would like to ask what is your opinion on the entitlement offer? I am entitled to some 15000 shares @0.55c, and inclined to take up on the offer. There is something which is worrying me a bit. AEP is the largest shareholder (correct me if I am wrong),and they had taken up all the entitlement, as announced by IBA. My worry is that AEP can decide to sell part or whole entitlement they bought at 0.55c and I am afraid of what impact that would have on IBA sp. Also I don't understand why people would be selling IBA shares now, why don't they wait for their entitlement offer??? Regards to you all IBA team.
