"The group has seen increased client acquisition for retail spread betting and CFDs in the second half of the year with 30% of applications now being received from international jurisdictions as the group pursues its strategy of overseas expansion."
It says that UK financial spread betting achieved record daily trade volumes with average trades per day increasing to 33,042 (2010: 29,832) and net revenue per active client increasing 7% to Â£1,370 (2010: Â£1,279) for the year.
