New Trading Tariffs

Posting of New Trading Tariffs



17 January 2007



The London Stock Exchange ('the Exchange') has today, in line with normal
practice, written to customers to advise them of its new trading tariffs for the
financial year beginning 1 April 2007.



In formulating these changes the Exchange has taken account of its overarching
principles of encouraging and rewarding liquidity provision, facilitating new
customer trading strategies and enhancing market efficiency. Lower fees
stimulate volume growth and increase liquidity, which, in turn, reduce overall
transaction costs.



Details of the tariff changes can be found on the Exchange's website*. The
changes will be phased in between April and November, and show:

•        A decrease in the SETS Exchange charge for aggressive trades.

•        The equivalent passive tariff remains free.

•        A deeper volume discount scheme, which will enable firms to benefit
         sooner from lower charges.

•        The introduction of 'SETS Internaliser', a lower tariff for self
         executions, which will incentivise firms to move internalised trades 
         onto the order book.

•        A new discounted trade reporting tariff to support the introduction of
         our MiFID European Trade Reporting service.

2007 will be an important year for the Exchange with the launch of TradElect,
its new trading platform, in the second quarter. A review of trading tariffs in
December 2007 will take into account, amongst other factors, the volume growth
resulting from this particular development.



In terms of quantifying these fee reductions, if the new tariffs had been
applied from the beginning of the current financial year, SETS order book yield
for the period 1 April to 31 December 2006 would have moved from £1.36 to £1.23
per trade, (based on an average 324,000 daily SETS trades for the nine months);
UK off-book yield would have reduced from £0.89 to c£0.20 per trade (based on
41,000 average daily trades for the nine months). IEM revenue totalling £3m for
the nine months year to date will fall away, to be replaced by the new European
Trade Reporting service.



The Board believes that the above tariff reductions, together with the
introduction of TradElect will stimulate new and additional trading activity and
is confident that Broker Services will continue to deliver strong revenue
growth.



The Exchange will provide its expectation of volume growth for the next
financial year in our next shareholder circular to be released by 20 January
2007.
