Commenting on performance of the Group, Xavier Rolet, Chief Executive said:

"Our diversification strategy is delivering. Today I am pleased to be reporting a strong first half performance across the Group with a 20 per cent rise in total income and a 79% per cent increase in profit before tax.

"Key highlights include a very good performance from Post Trade, an area we highlighted in 2009 as a core focus for us and which is now making a significant contribution to both Group revenue and growth. During the period we also successfully launched Turquoise Derivatives, launched MTS Gilts and a number of other new indices, secured new MillenniumIT contracts, continued to drive momentum in our UK Order Book for Retail Bonds and agreed to acquire the FSA's trade reporting service, TRS. In addition, we also remain actively engaged in exclusive discussions with LCH.Clearnet about a potential transaction.

"Our balanced and diversified business, with a well-hedged, inversely-correlated portfolio of products and services, makes us strongly placed to take advantage of growth opportunities that the changing market and regulatory environment is presenting. Partnering with our clients to drive innovation and new services, strong cost control and our continued focus on new opportunities to grow the scale, scope and efficiency of the Group remain core. We are well placed to propel our business forward and successfully deliver on our growth strategy."
