Dubai property developer Emaar Properties intends to make a voluntary cash offer to acquire up to 100 per cent of the shares in its listed unit Emaar Development that it does not already own. The biggest listed developer in the emirate is offering Dh15 ($4.08) per share to investors to take full control of its subsidiary. The proposed offer is subject to approval by Emaar Properties’ board, the company said in a filing on Wednesday to the Dubai Financial Market, where its shares are traded.
