Commenting on performance in Q3, Xavier Rolet, Chief Executive, said:

'The Group continues to perform very well, with good revenue growth in our main businesses and a strong period of successful development and delivery. The completion of the acquisition of Citi Fixed Income Indices and The Yield Book is already contributing to the further growth in FTSE Russell while LCH continues to perform strongly and has launched innovative new services. I am also delighted that we are increasing our stake in the LCH Group.

'The Group's excellent financial performance is reflective of our continued innovation and execution of our growth strategy, enabling us to deliver against our three year financial targets. Together with our proven Customer Partnership and Open Access approach, this positions us strongly to benefit from the introduction of MiFID II in less than three months time.'

Organic growth is calculated in respect of businesses owned for at least 3 months in either period and so excludes The Yield Book and Citi Fixed Income Indices, ISPS, Mergent and SwapMatch. The Group's principal foreign exchange exposure arises from translating our European based Euro and US based USD reporting businesses into Sterling.

Investment in growth opportunities and new developments continued across the business:

• LSEG will increase its stake in LCH Group to 64.4% (on completion of regulatory processes before the end of 2017), acquiring an additional 6.63% following a sale by certain minority shareholders

• The Government Pension Investment Fund (GPIF) of Japan selected new FTSE Blossom Japan Index as a core ESG benchmark through its flagship fund
• Good flow of new issues on our UK and Italian markets, with a near doubling in the number of new issues year on year - in early October Borsa Italiana welcomed Pirelli to its market, the largest continental European IPO so far in 2017; together with Allied Irish Bank in the summer, the two largest European IPOs have been on Group markets
• Turquoise Lit Auctions, a pre-trade transparent and MiFID II compliant trading mechanism, received regulatory approval for Q4 2017 launch; and Turquoise Plato Block Discovery delivered record value traded in September (8 times the level of Q3 last year)
• CurveGlobal marked its first year in operation - the platform is building a firm foundation, with 1.5 million lots traded since launch (of which 40%of the volume traded was in the last three months)

Financial Position

Refinancing to extend Group debt maturities was successfully completed in September. The Group issued €500 million 0.875% 2024 bonds and €500 million 1.75% 2029 bonds, of which an aggregate €700 million was immediately swapped into USD to appropriately match Group currency of debt to currency of earnings. The resulting effective blended rate of interest on the bonds is fixed at c2.8% per annum until the first maturity date.

The Group's financial position remains strong, with good cash generation from operations offset by normal course interim dividend and bond coupon payments, and the conclusion of the £200 million share buyback programme. We also continue to invest in projects to support growth initiatives. During the period the Group completed the acquisition of the Citi Fixed Income Indices and The Yield Book, paying US$685 million. At 30 September 2017, the Group's committed facility headroom was c£700 million, available for general corporate purposes.

The euro and US dollar both strengthened by 8% against sterling compared with the same period last year. To illustrate our exposure to movements in exchange rates, a €0.05 change in the average euro:sterling rate would have resulted in a change to continuing operations total income of c£6.9 million for Q3, while a US$0.05 move would have resulted in a c£4.8 million change.

Current trading

The Group continues to execute on its successful growth strategy to deliver attractive shareholder returns. All main parts of the Group continue to perform well and investment remains ongoing on a number of initiatives. We are well positioned for the introduction of MiFID II and a broader changing regulatory environment.

The Group released a separate statement this morning regarding succession planning.
