Clearnet urges investors to back LSE takeover bid However, because the LSE has now committed to the rights issue, the London bourse may have to stump up an extra €180m. If the LSE chose to take up its full rights, then the total spend on LCH.Clearnet will rise to €545.4m - 18pc more than LSE would have spent under the original terms. LCH.Clearnet is owned by the banks that use its clearing services, which together hold 77.5pc. The remaining 22.5pc is held by exchanges, including LME and NYSE Euronext. Regulators are keen to force banks to channel their trades through clearing houses to help monitor risk positions. However, under new European regulations, clearing houses will be forced to hold more capital so there is a bigger financial buffer in the case of default. In September, LCH.Clearnet estimated it would need an additional €300m to €375m to meet the requirements.
