Table 3 reports the share for the larger tax havens listed in Table 1 for which data are available,
plus the Netherlands. In general, U.S. source profits as a percentage of GDP are considerably
larger than those in Table 2. In the case of Luxembourg, these profits were 18% of output in 2004
and 127% in 2010. Shares are also very large in Ireland and the Netherlands (42% and 17%,
respectively), where they have both grown substantially. Shares in Switzerland and Cyprus have
also grown. In most cases, the shares are well in excess of those in Table 2.
