The combined value of non-UK companies listed on London's Alternative Investment Market and incorporated on the Isle of Man now exceeds that for any other jurisdiction, according to research commissioned by law firm Cains. Examining the top 100 non-UK companies listed currently on AIM, the report reveals that Isle of Man incorporated companies in this group have a combined market capitalisation of £6,240 million ($12,620 million), propelling the Isle of Man into first place, ahead of Canada. The latest figure is an increase of 16 per cent on April 2007's total of £5,222 million and also exceeds the combined value of companies listed in Canada (£2,268 million), the British Virgin Islands (£1,926 million) and Australia (£1,671 million), which rank second, third and fourth respectively. Cains currently ranks as the Isle’s top law firm based on the market capitalisation of AIM clients, advising companies valued at an aggregate of £4,734 million. The firm also sits fourth in the overall UK rankings. Meanwhile, the Isle of Man continues to lead the way in terms of the number of AIM 100 listed companies incorporated within its boundaries, its total of 15 keeping it in first place ahead of Bermuda (6) and more than Channel Islands Guernsey (5) and Jersey (4) combined. The research also shows that, when looking at AIM as a whole, the Isle of Man has now joined Guernsey as the jurisdiction most preferred by non-UK companies. Both islands now have 57 companies listed.
