Ann: Suspension from Official Quotation, page-17

I'm not 100% sure, but one way they can acquire the shares is for some shareholders to willingly sell them. There are different types of takeovers and it depends on the percentage they're buying. There may need to be a shareholder vote too, but if it's an offer where you get to decide whether you keep or sell, they need to put out a brochure and the board puts out a recommendation to say whether or not it's a good deal for you as a shareholder. Maybe someone else can elaborate.
