Like many Asian conglomerates, the Li Ka-shing group is structured to retain disproportionate control without incurring the cost of owning an equivalent economic interest. This separation between control and interest is accomplished through pyramid structure, dual-class equities and cross-holdings.[citation needed] While such structures are rarer in the US and UK, they do exist. For instance, Google uses a dual-class structure to give its founders and insiders 10 votes for each class-B share while the general public is offered class-A shares with 1 vote each.
