UPDATE 1-LSE sees acquisition of LCH.Clearnet within Q1 -report

MILAN, Dec 17 (Reuters) - The London Stock Exchange

expects to finalise its acquisition of clearing house

LCH.Clearnet within the first quarter of next year, LSE Chief

Executive Xavier Rolet told Italian daily Il Sole 24 Ore on

Sunday.

Britain's competition watchdog on Friday gave a green light

to the London Stock Exchange Group Plc's planned purchase of

LCH.Clearnet.

But both parties are back in talks over terms to reflect

higher capital requirements being imposed on exchanges by

European regulators overhauling the financial system after the

banking crisis.

"Capital shortfall for LCH is said to be around 300-375

million euros and it could be even higher, this is why we are in

talks to change the terms of the deal," said Rolet, adding he

expected the deal would be done "into Q1". He said that still

depended on a green light from European regulators.

"We have already put aside the majority of funds we will

need," he said.

A spokesperson for the LSE welcomed the go ahead from

Britain's competition watchdog, but declined further comment.

Under the deal terms agreed in April, the LSE would buy up

to 60 percent of the clearing house for 19 euros per share.

However it would also have to pay 60 percent of the capital

increase imposed by the European Securities and Markets

Authority (ESMA) to LCH.Clearnet. The ESMA may not finalise its

demands until early next year.
