The London Stock Exchange Group Monday agreed to pay €15 per share for a 60% stake in clearing house LCH.Clearnet as the companies extend negotiations and inch towards an agreement that has been delayed by new European regulations.

The change in terms, from an original offer of €20-per share back in March, comes after weeks of new negotiations between the LSE and LCH over the price, triggered by ongoing regulatory changes surrounding the capital of clearing houses in Europe.
