I don't have all the figures in front of me, but to my knowledge the most export-intensive part is the transportation sector. If I remember correctly, about 15% of its revenues come from exports. Other segments can be lower. Financial services, if I remember correctly, are at about 8% of sales. There are some segments that are more export-intensive than others. And there are some that are not very export-intensive—for instance, the retail trade is almost entirely domestic.
