How it works

Trade Management

All transactions that are submitted to LCH.Clearnet SA are registered in its system CLEARING 21® in the name of the clearing member. Upon registration novation occurs. As a result of novation, LCH.Clearnet SA becomes counterparty to the clearing member and becomes therefore subject to the rights and subject to the obligations arising from the transaction registered in the name of such clearing member.

Position management

LCH.Clearnet SA aggregates trade legs with respect to payment of cash or delivery of securities, into open positions. The trade legs and open positions are managed within positions accounts. The clearing members can modify the posting into the positions accounts, when needed, using corrections, give-ups, transfers.

Settlement management

LCH.Clearnet SA together with Euroclear Group have designed a settlement solution, Euronext Stock Exchange Settlement (ESES). This
solution offers clearing members the possibility to settle their exchange trades against LCH.Clearnet SA on a Delivery-Versus-Payment - DVP – basis via the settlement platform of their choice (Euroclear Bank or the domestic Central Securities Depository) i.e. :

• Euroclear France or Euroclear Bank for Clearing Members working on Euronext Paris
• Euroclear Belgium  or Euroclear Bank for Clearing Members active on Euronext Brussels,
• Euroclear Netherlands or Euroclear Bank for Clearing Members active on Euronext Amsterdam and LSE DTS,
• Interbolsa  for Clearing Members active on Euronext Lisbon.

Risk Management

For transactions registered in CLEARING 21®, margins are required to cover:

• the liquidation risk,  the open positions value variation in case of unfavourable market evolution;
• the negotiation risk, which covers the open positions past
  variations ("marked to market").

LCH.Clearnet SA informs clearing members of the amount relative to the margins required on the morning of their eligibility. The calculations are made using SPAN ®.

Furthermore, a Clearing Member is obliged to contribute to the clearing fund. Once a month LCH.Clearnet SA shall determine the size of the clearing fund and the level of each individual clearing member's contribution. The total amount that may initially be called must, at a minimum, cover the price risk run by the clearing member in respect of its largest uncovered risk.

Default Management

In case a clearing member does not fulfil its payment or delivery obligations LCH.Clearnet initiates sell-out or buy-in procedures. If LCH.Clearnet SA is unable to deliver a given financial instrument, pursuant to the market conditions, LCH.Clearnet SA will pay a cash amount in lieu of delivery to the clearing member suffering from the default. Those procedures are at the defaulting clearing members expense. In case of real global default others measures can be taken.
