The more money companies spend on items not essential to their own success, the more risks they are taking. If the theme park business were to take a major plunge, AB would lose money by operating their theme parks. Now, theme parks have nothing to do with the manufacturing of beer, so it is nonessential. Why spend money in areas that you don't necessarily need to boost your company? AB doesn't need the publicity. Nonessential assets create risks, and that is one thing that some companies do not want to deal with.
