The group reports a 4.2 per cent revenue rise for the nine months to 30 September 2011.
The company also said business remains on track to deliver full-year expectations despite the tough economic conditions.
The events and training division posted revenue growth of 5.2 per cent and events are proving “a resilient market and we are looking to expand more into developing markets such as Brazil and the Middle East", according Head of Investor relations James Gareh.
"We have seen the group make further positive developments this year with value, creating strategic acquisitions in both high growth emerging markets and key industry verticals,” said Chief Executive Peter Rigby. “At the same time, we have enhanced the business with an increase in the number of highly resilient events as well as further growth in subscription revenues.”
