1. Introduction
1.1. This Practice Note illustrates the apportionment and application of Clearing Fund Contributions when one or more auctions are held in respect of a Contract Class. For the purposes of this Practice Note, the Contract Class specified in Rule 7A.01A.5.a, which comprises of (i) contracts that are listed for trading on the Exchange or Relevant Market and (ii) Non-Relevant Market Contracts, will be referred to as the "ETD and NMC Contract Class", the contracts collectively as "ETD and NMC Contracts", the Contract Class and an auction held in respect of this Contract Class as an "ETD and NMC Auction".
1.2 This Practice Note describes:
i. the apportionment of the Clearing House First Loss Contribution, Clearing House Intermediate Contribution, and the Clearing Fund Deposit of each Clearing Member, where one or more ETD and NMC Auctions are held pursuant to Rules 7A.01A.2C.2, 7A.01A.2D.2, and 7A.01A.2E.2; and
ii. the use of Required Participants' Clearing Fund Deposits based on their bidding behaviour in an ETD and NMC Auction, pursuant to Rule 7A.01.2D.2.
2. Apportionment of Clearing House First Loss Contribution and Clearing House Intermediate Contribution to auctions held in respect of the ETD and NMC Contract Class
2.1 For each ETD and NMC Auction, the Clearing House First Loss Contribution and Clearing House Intermediate Contribution shall be apportioned to that auction, based on the proportion of the notional value of the Auction Portfolio vis-à-vis the aggregate notional value of the defaulted Clearing Member's contracts in the ETD and NMC Contract Class.
3. Apportionment of a Required Participant's Clearing Fund Deposit to an ETD and NMC Auction
3.1 For each ETD and NMC auction, the Clearing Fund Deposit of each Required Participant shall be further apportioned to that auction based on the proportion of the notional value of the Required Participant's contracts that are the same as those in the Auction Portfolio vis-à-vis the aggregate notional value of all of that Required Participant's contracts in the ETD and NMC Contract Class.

a. first, the apportioned Clearing Fund Deposits of Required Participants who did not participate in the auction;
