Currently LSEG and Pearson both own 50 per cent shares in the firm - but the publisher has agreed to sell its share to the exchange as part of a deal which is expected to close by the end of the first quarter of 2012.
David Lester, director of information services at the LSE and chairman of FTSE International, said: âIt is an excellent fit for our growing derivatives operations and will help us develop new tradeable products.â
Marjorie Scardino, Pearsonâs chief executive, said: âFor Pearson, the transaction further strengthens our financial position at a time of significant macroeconomic turbulence.â
The sale of Pearsonâs share in the FTSE follows its previous sale of a stake in Interactive Data for $2 billion.
According to Pearson, the sale will enable it to expand in other business areas such as digital and subscription models.
Pearson is owned by the FT Group which is also responsible for managing Penguin books.
