Wessal made an offer to purchase 25% at the end of the Emaar deal. Those are the only numbers Wessal knew of at the time of the offering. At the time that is insider knowledge. However, since Wessal had not bought at that time there is nothing illegal about an offering to buy stock. The PR about the Emaar deal and the PR about Wessal buying then makes everything public knowledge and allows them to begin buying.
