2010 was a year with a mixed performance across the business, says Richard Last, Chairman, of Patsystems. We saw some notable sales successes, such as the new customers for our exchange system offering, tempered against deferred sales opportunities for our risk product and marginal growth within our trading systems business.

The Group continues to demonstrate continued cash generation and profit resilience and we expect this to continue in 2011 and beyond. The continued payment and growth in the level of the dividend is an important statement by the Board of our continued confidence in the growth prospects for the business. Patsystems commences 2011 with an encouraging sales pipeline that will provide opportunity to expand our geographical presence and grow the revenues for each of our product offerings.
