others within NEX SEF, NEX SEF's Affiliates or to outside advisers thereof or other service

confidentiality obligations, and that, in each case, such disclosure is necessary for the performance 

of Facility-related duties by the individual or entity, (ii) if required by a Regulatory Agency, or (iii) if 

compelled to do so by valid legal process, provided that the individual or entity notifies NEX SEF

Rule 104 Emergency Action

(a) Definitions. As used in this section:

The term "Emergency" shall mean any occurrence or circumstance which, in the opinion of NEX SEF, 

requires immediate action and threatens or may threaten such things as the fair and orderly trading in, or 

the liquidation of, or delivery pursuant to, any Contracts on the Facility, including any manipulative or 

attempted manipulative activity; any actual, attempted, or threatened corner, squeeze, congestion, or 

undue concentration of positions; any circumstances which may materially affect the performance of 
13

Contracts traded on the Facility, including failure of the payment system or the bankruptcy or insolvency of 

any Participant; any action taken by any Competent Authority, or any other board of trade, swap execution 

facility, market or facility which may have a direct impact on trading on the Facility and any other 

circumstance which may have a severe, adverse effect upon the functioning of the Facility.

(b) Emergency action may be taken by the following:

(1) by the Board in the case of any Emergency;

(2) by any two members of the Board in the case of any Emergency where it is 

impracticable in the opinion of the Chairman of the Board or in his or her absence, any two members 

of the Board, to call a meeting of the Board to deal with the Emergency; or

(3) by any committee of NEX SEF pursuant to powers conferred on said committee 

under the Rules or by the Board. 

(c) Vote Required. The vote required of the Board or committee authorised to take any 

Emergency action hereunder shall be:

(1) in the case of action by the Board, the affirmative vote of a majority of the members 

of the Board present and voting at a meeting at which there is a quorum; or

(2) in the case of action by a committee, the affirmative vote of two or more persons 

constituting not less than a majority of the members of said committee present and voting at a 

meeting at which there is a quorum.

The consent in writing to any Emergency action of all members of the Board or of a committee, as 

applicable, shall be sufficient to take such Emergency action without a meeting. A member of the Board or 

of a committee shall be deemed present or in attendance at a meeting if such a person participates in the 

meeting by means of a conference telephone or similar communications equipment allowing all persons 

participating in the meeting to hear each other at the same time.

(d) Action which may be taken:

(1) In the event of an Emergency, NEX SEF may, subject to Part 40 of the Commission 

Regulations under the Act, place into immediate effect a Rule which may provide for, or may 

authorise NEX SEF, or any committee, to undertake actions which, in the opinion of NEX SEF are 

necessary or appropriate to meet the Emergency, including, but not limited to, such actions as:

(i) extending or shortening the expiration date for trading in Contracts;

(ii) extending the time of delivery under or expiration of Contracts;

(iii) extending, limiting or changing hours of Trading Sessions;

(iv) imposing or modifying price limits;

(v) imposing or modifying Position Limits;

(vi) imposing or modifying intraday market restrictions;

(vii) ordering the liquidation or transfer of open positions in any Contract; 

(viii) ordering the establishment of a settlement price;

(ix) suspending trading pursuant to Rule 105 or curtailing trading in any 

Contract; 
14

(x) removing any one or more Contracts from trading on the facility;

(xi) cancelling any Bid/Offer;

(xii) altering any Contract's settlement terms or conditions prior to execution 

and adjusting or cancelling any executed transaction pursuant to Rule 315;

(xiii) modifying or suspending any provision of the Rules; and

(xiv) adjusting, winding down or closing the Facility.

(2) In the event of an Emergency when a quorum of the Board is not available, all 

trading on the Facility may be suspended by an affirmative vote of a majority of the Directors 

present, or by action of one Director if only one Director is present, for such period of time as in 

their or his or her judgment is necessary. In the event of an Emergency which prevents normal 

attendance at a meeting of the Board, when no Director is present, any authorised officer of NEX 

SEF shall have authority to order suspension of trading on the Facility for such period of time as in 

his or her judgment is necessary. Any action taken under this paragraph (d) shall be subject to 

review and modification by the Board.

(3) Whenever any action is taken under this Rule pursuant to which trading is 

suspended or other changes in procedure are made, all matters relating to notices, deliveries and 

other obligations may be suspended or deferred in such manner as the Board or committee, as the 

case may be, may determine.

(4) NEX SEF may be required to take an Emergency action when directed by the FCA 

or the Commission. If a Contract is traded both on the Facility and on one or more other SEFs, 

any Emergency action to liquidate or transfer of open positions in any Contract will be made in 

consultation with the Commission or Commission staff.

(e) Physical Emergencies

(1) In the event the physical functions of the Facility or NEX SEF are, or are threatened 

to be, severely and adversely affected by a physical emergency, such as fire or other casualty, 

bomb threat, substantial inclement weather, power failure, communication or transportation 

breakdown, computer malfunction, screen-based Trading Platform break-down, malfunction of 

plumbing, heating, ventilation and air conditioning systems, or a backlog or delay in clearing or in 

the processing of data related to clearing Cleared Contracts (a "Physical Emergency"), the 

Chairman of the Board, or in his or her absence the Chief Executive Officer, or in both of their 

absences any other authorised officer may take any action which, in the opinion of such officer is 

necessary or appropriate to deal with the Physical Emergency, including, but not limited to, 

suspending trading in any one or more Contracts, delaying the opening of trading in any one or 

more Contracts, extending the Last Trading Day and/or the time of trading.

(2) In the event a designated officer has ordered suspension of trading, the Chairman 

of the Board or the Chief Executive Officer, or in their absence any other authorised officer may 

order restoration of trading on the Facility, or may remove other restrictions so imposed, if such 

officer determines that the Physical Emergency has sufficiently abated to permit the physical 

functions of NEX SEF or the Facility to continue in an orderly manner.

(f) NEX SEF will promptly submit a written report detailing any action taken hereunder to the 

Commission and the FCA and such written report shall explain the decision-making process, the reasons 

for the exercise of emergency authority and how any conflicts of interest were addressed. Any emergency 
15

Rule or Rule amendment shall be filed with the Commission in accordance with Part 40 of the Commission 

Regulations under the Act.

(g) In exercising its authority under this Rule 104, NEX SEF shall, in its reasonable discretion, 

and where appropriate, permitted by Applicable Law and not precluded by exigent circumstances, consult 

and coordinate with DCOs, other swap execution facilities, boards of trade, relevant Participants, and other 

parties in considering what actions to take hereunder.

(h) In exceptional circumstances and following a request from a Participant, NEX SEF may 

decide, in its absolute discretion, to authorise a specific order or set of orders which exceed the parameters 

of the Pre-Trade Controls. Any such request by a Participant must be in written or electronic form and must 

be sent to the Compliance department of NEX SEF. NEX SEF shall communicate its decision as to 

authorisation in written or electronic form. Any authorisation given pursuant to this sub-paragraph shall be 

temporary and shall be restricted to the order(s) specified by NEX SEF. 

Rule 105 Suspension of Trading

The Board may, in its discretion, by an affirmative vote of a majority of the Directors present at a meeting 

at which there is a quorum (which, in an Emergency other than a Physical Emergency, may be held without 

previous notice):

(a) suspend or remove any one or more of the Contracts in accordance with its business 

needs; and

(b) suspend or remove from trading any one or more Contracts which no longer complies with 

the Rules unless such suspension or removal would be likely to cause significant damage to the interests 

of Participants or Customers or the orderly functioning of the market.

Any decision made by the Board in accordance with this Rule 105 to suspend or remove from trading any 

one or more Contracts shall be made public on the Facility's website and shall be communicated to the

relevant Competent Authority.

Rule 106 Risk Controls for Trading

The Regulatory Oversight Committee may impose controls to reduce the potential risk of market disruption, 

including, but not limited to, market restrictions that pause, halt or constrain trading in specified market 

conditions.

Rule 107 Market Data

(c) Notwithstanding paragraph (b) of this Rule 107, solely (i) for use in connection with a

departments/functions) or (ii) to the extent necessary for a Trading Privilege Holder's information 

technology department to perform transaction-related support functions for such Trading Privilege Holder, 

Trading Privilege Holders that pay the required monthly fees, as described in NEX SEF's Trade Execution

as such Losses arise out of or in connection with, or are based upon any Proceeding against a NEX SEF 

Indemnified Party that arises out of or relates to any Derived Information created by or on behalf of such 

Trading Privilege Holder or any of its Related Parties. 

Rule 108 Intellectual Property

Intellectual Property Rights in the Systems are a valuable asset of NEX SEF or its affiliates or 

licensors or their respective successors. Each Participant shall protect and safeguard the

Participant generally uses to protect its own Intellectual Property Rights and business assets, but 

in any event with no less than a reasonable degree of care.

(2) Each Participant shall promptly notify NEX SEF upon becoming aware of any 

infringement or misappropriation of any Intellectual Property Rights of NEX SEF or its affiliates or

Platform, which includes but is not limited to the technology known as EBS Dealing Service and 

Brokernet), or the use thereof by the Participant Indemnified Party as authorised hereunder, 

violates any Intellectual Property Rights of any third party provided that such Losses do not result 

from (i) any Participant Indemnified Party's fraud, gross negligence or willful misconduct; 

(ii) violation of Applicable Law by the Participant Indemnified Party; or (iii) the Participant's breach 

of the Rules.

(2) Each Participant shall defend, indemnify and hold harmless NEX SEF and each 

NEX SEF Party (each a "NEX SEF Indemnified Party") from and against any Losses to which any 

NEX SEF Indemnified Party may become subject, insofar as such Losses arise out of or in 

connection with, or are based upon any Proceeding against a NEX SEF Indemnified Party that 

arises out of or relates to any access, use or misuse of the Systems by the Participant or by any 

person accessing the Systems using the Participant's ID provided that such Losses do not result 

from: (i) a NEX SEF Indemnified Party's fraud, gross negligence or wilful misconduct; (ii) violation

breach of the Rules.

Rule 108 (the "Indemnified Party"), notice shall be given to the party obligated to provide such 

indemnification (the "Indemnifying Party") as soon as reasonably practicable. The Indemnifying 

Party shall be entitled to take control of the Proceeding and any settlement of it, and the Indemnified 

Party shall give the Indemnifying Party, at the Indemnifying Party's reasonable cost, all reasonable 

assistance in relation to the Proceeding.

(4) Notwithstanding anything to the contrary contained in Rule 102 or a System 

Protocol, no limitation or exclusion of liability shall apply with respect to any direct losses or claims 

based on confidentiality, or to NEX SEF's intellectual property infringement indemnification 

obligations set forth in this Rule 108.

(g) Confidentiality 

Each Participant shall keep confidential all Confidential Information of NEX SEF or NEX SEF's affiliates or 

licensors, both during the term and after termination of the license granted by this Rule 108. Each 

Participant may disclose Confidential Information to its professional advisers but otherwise may only 

disclose Confidential Information to those of its employees and representatives who need to know such 

Confidential Information for the purposes of exercising or performing the rights and obligations of Participant

(1) General Privileges. Subject to the requirements and procedures set forth in this 

Chapter 2, Trading Privileges will be granted on an impartial basis to all applicants from time to

restrictions from time to time imposed by NEX SEF. Trading Privileges are non-transferable 

(except under certain limited circumstances which must be approved by NEX SEF), non-assignable 

and may not be sold or leased. Circumstances under which Trading Privileges may be transferred, 

subject to NEX SEF approval, include, for example, transfers due to corporate reorganisations. 

Each Trading Privilege Holder will have the right to access the Facility (including, subject to the 

applicable System Protocol, any Trading Platform) including the right to:

(i) place Bids/Offers and Pre-Arranged Crosses for itself as principal or for 

the accounts of Customers as an Intermediary pursuant to Rule 201(a)(2); 

and

(ii) appoint other persons to act on its behalf as an Authorised Trader or 

Authorised Trading Firm pursuant to Rule 202.

(2) Approved Capacities. As approved by NEX SEF and where permitted under this 

Rulebook and by Applicable Law, a Trading Privilege Holder may also act as: 

(i) a Customer, and in this capacity may appoint one or more other entities to 

act on its behalf as an Authorised Trading Firm pursuant to Rule 202;

(ii) an Intermediary, and in this capacity may place Bids/Offers and 

Pre-Arranged Crosses in the name of and on behalf of Customers; or

Holder to enter into transactions in the name of and on behalf of the Prime 

Broker pursuant to Rule 215.

(3) By virtue of obtaining Trading Privileges, a Trading Privilege Holder will not obtain 

any equity or other interest in NEX SEF or the Facility, including voting rights or rights to receive 

any dividends or other distributions, whether arising from a dissolution, merger or consolidation 

involving NEX SEF, the Facility or otherwise.

(4) In granting Trading Privileges, NEX SEF may impose such restrictions or 

limitations as it may deem necessary or appropriate, and in accordance with Applicable Law. NEX 

SEF shall apply such restrictions or limitations to applicants in an impartial, non-discriminatory 

manner, consistent with Applicable Law. NEX SEF will deny the grant of Trading Privileges where 

an applicant has failed to meet any requirements for such grant.

(b) Financial Requirements

to guarantee the adequate settlement of transactions and must meet the other financial and related 

reporting requirements set forth in this Rule 201.

participant" as defined in the Act upon initial application for Trading Privileges.

(3) Each Trading Privilege Holder shall, no less frequently than annually, provide NEX 

SEF either with (i) its annual financial report that it provides to the Commission or (ii) a written or 

electronic representation providing that such Trading Privilege Holder has been, and continues to 

be as of such date, an "eligible contract participant" as defined in the Act.

(4) Each Trading Privilege Holder must notify NEX SEF's Compliance Function 

immediately upon becoming aware that it fails to satisfy the minimum financial requirements 

applicable to it.

(5) Unless and until a Trading Privilege Holder is able to demonstrate to NEX SEF 

that it is in compliance with the minimum financial requirements applicable to it, such Trading 

Privilege Holder may not engage in any transactions subject to the Rules of the Facility, except for 

the purpose of closing open positions that were opened on the Facility.

(c) Fitness Standards

(1) NEX SEF may deny the grant of Trading Privileges, or may prevent a person from 

becoming an Intermediary or a Trading Privilege Holder, if such person:

applicable Rules of the Facility or any Regulatory Agency, Rule of any 

DCO to which the Trading Privilege Holder submits Cleared Contracts for 

clearing; Commission Regulations and SRO regulations, including those 

concerning recordkeeping, reporting, financial requirements and trading 

procedures; 

(ii) would bring NEX SEF or the Facility into disrepute; or

(iii) is otherwise not fit and proper to be a Trading Privilege Holder or 

Intermediary.

(2) NEX SEF may determine not to permit a Trading Privilege Holder or Intermediary

to keep its, his or her Trading Privileges or maintain its, his or her association with a Trading 

Privilege Holder, as the case may be, if such Trading Privilege Holder or Intermediary:

(i) fails to meet any of the qualification requirements for Trading Privileges or 

Intermediary status after such Trading Privileges or Intermediary status 

have been approved;

(ii) fails to comply with any limitation placed by NEX SEF or under Applicable 

Law on such Trading Privileges or Intermediary status; or

Rule 201(b)(i). 

(e) NEX SEF may (i) deny the grant of Trading Privileges, (ii) prevent a person from becoming 

an Intermediary, or (iii) determine not to permit a Trading Privilege Holder or any Intermediary that is not a 

Trading Privilege Holder to keep its, his or her Trading Privileges or maintain its, his or her association with 

a Trading Privilege Holder, as the case may be, if such Trading Privilege Holder or Intermediary causes or 

would cause NEX SEF to be in violation of Applicable Law.

(f) Intermediation

(1) A Trading Privilege Holder may not act as an Intermediary for any other entity or 

person, unless the Trading Privilege Holder does so in accordance with Applicable Law.

(2) A Trading Privilege Holder may not transact as an Intermediary for any Customer 

unless the Trading Privilege Holder has submitted a signed representation to NEX SEF that each 

of its Customers is an "eligible contract participant" as defined in the Act and as an Eligible 

Counterparty. 

(3) A Trading Privilege Holder may appoint an Authorised Trading Firm to act as an 

Intermediary upon the approval of NEX SEF.

Bids/Offers, submit Pre-Arranged Crosses, access a Trading Platform and effect transactions in Contracts 

on the Facility. Such authority may be granted to one or more Authorised Traders or Authorised Trading 

Firms.

(1) Authorised Traders.

(i) Each Trading Privilege Holder which is trading for its own account as a 

principal may permit one or more individuals as Authorised Traders to

made on its behalf by such Authorised Traders or to one or more 

Authorised Trading Firms.

(ii) Each Trading Privilege Holder which is an Intermediary trading for the 

accounts of Customers may permit one or more individuals as Authorised 

Traders to enter Bids/Offers and Pre-Arranged Crosses for such 

Customers. In such cases, the Trading Privilege Holder has responsibility 

for all actions and failures to act of such Authorised Traders, but the 

Customer on whose behalf each transaction is made shall be the principal 

to any transactions made on its behalf by such Authorised Traders. 

(iii) Each Trading Privilege Holder that is authorised by a Prime Broker under 

a Prime Broker Agreement to enter into transactions in the name of and 

on behalf of a Prime Broker and for which a Prime Broker Representation

with reasonable care in granting Authorised Trader status. 

(2) Authorised Trading Firms.

(i) Each Authorised Trading Firm which is an Intermediary trading for the 

accounts of Customers may permit one or more individuals as Authorised 

Traders to enter Bids/Offers and Pre-Arranged Crosses for such 

Customers. In such cases, the Authorised Trading Firm has responsibility 

for all actions and failures to act of such Authorised Traders, but the 

Customer on whose behalf each transaction is made shall be the principal 

to any transactions made on its behalf by such Authorised Traders.

(ii) Each Trading Privilege Holder which is a Customer may designate one or 

more Authorised Trading Firms to enter Bids/Offers and Pre-Arranged 

Crosses on its behalf as an Intermediary. In such cases, the Trading 

Privilege Holder has responsibility for all actions and failures to act of such 

Authorised Trading Firm and its Authorised Traders.

(iii) The Trading Privilege Holder shall be responsible to NEX SEF for acting 

with reasonable care in granting Authorised Trading Firm status. 

(iv) Each Trading Privilege Holder will obtain a signed written or electronic 

representation, prior to being granted access to the Facility, that each of 

its Authorised Trading Firms continues to qualify as an "eligible contract 

participant" as defined in the Act and provide such representation to NEX 

SEF and shall notify NEX SEF if any Authorised Trading Firm no longer 

qualifies as an "eligible contract participant".

(b) NEX SEF Approval

(1) No person may act as an Intermediary, Authorised Trader or Authorised Trading 

Firm before being approved to do so by NEX SEF, which NEX SEF will do on an impartial basis.

(2) Each prospective Intermediary, Authorised Trader and Authorised Trading Firm, 

or the Trading Privilege Holder on their behalf, will, prior to being permitted by NEX SEF to act as 

an Intermediary, Authorised Trader or Authorised Trading Firm, as the case may be, submit an 

application in the form required by NEX SEF and will satisfy such requirements as may be 

prescribed by NEX SEF from time to time. 

(3) Each prospective Authorised Trading Firm, or the Trading Privilege Holder on its 

behalf, must provide a written or electronic representation, prior to being granted access to the 

Facility, that the Authorised Trading Firm qualifies as (x) an "eligible contract participant" as defined 

in the Act, and (y) a Professional Client or an Eligible Counterparty, and that it has all registrations, 

licenses and consents required by its constituent documents and Applicable Law to transact in 

Contracts. The foregoing representation may be provided directly to NEX SEF by the Authorised 

Trading Firm in a form provided by NEX SEF or, alternatively, the Trading Privilege Holder may 

provide NEX SEF evidence satisfactory to NEX SEF that the Authorised Trading Firm has provided 

such consents, agreements and representations to the Trading Privilege Holder. 

(c) Responsibilities to NEX SEF 

(1) Each Trading Privilege Holder shall notify NEX SEF in writing if its relationship with 

an Authorised Trader or Authorised Trading Firm has been terminated, and such Trading Privilege 

Holder may at any time revoke any authorisation granted by it to any Authorised Trader or 

Authorised Trading Firm by providing written notice of such revocation to NEX SEF.
23

(2) By permitting any of its Authorised Traders and/or Authorised Trading Firm to 

access and use the Facility (including any Trading Platform) from any jurisdiction or to act as an 

Intermediary for trades on behalf of Customers located in any jurisdiction, each Trading Privilege 

Holder represents and warrants that each such access to or use of the Facility, or action as an 

Intermediary, does not violate any law applicable to the Trading Privilege Holder, the Authorised 

Trader, the Authorised Trading Firm or, to such Trading Privilege Holder's knowledge, NEX SEF.

(d) Fitness Standards

(1) NEX SEF may prevent a person from becoming an Intermediary, Authorised 

Trader or Authorised Trading Firm, if such person:

(i) is unable satisfactorily to demonstrate a capacity to adhere to all 

applicable Rules of the Facility or any Regulatory Agency, Rules of any 

DCO to which the Trading Privilege Holder submits Cleared Contracts for 

clearing, Commission Regulations and SRO regulations, including those

Intermediary, Authorised Trader or Authorised Trading Firm.

(2) NEX SEF may determine not to permit an Authorised Trader or Authorised Trading 

Firm to maintain its, his or her association with a Trading Privilege Holder or Authorised Trading 

Firm, as the case may be, if such Authorised Trader or Authorised Trading Firm:

(i) fails to meet any of the qualification requirements for Authorised Trader or 

Authorised Trading Firm status after such Authorised Trader or Authorised 

Trading Firm status has been approved;

(ii) fails to comply with any limitation placed by NEX SEF on such Authorised 

Trader or Authorised Trading Firm status; or

(iii) commits a material Violation.

(3) NEX SEF may prevent a person from becoming an Authorised Trader or 

Authorised Trading Firm, if they do not have a sufficient level of trading ability and competence or 

adequate organisational arrangements.

(4) Any decision made by NEX SEF pursuant to this Rule 202 must be consistent with 

both the provisions of this Rule and the Applicable Law.

(e) Intermediation

(1) An Authorised Trading Firm may not act as an Intermediary for any other entity or 

person, unless the Authorised Trading Firm does so in accordance with Applicable Law.

(2) An Authorised Trading Firm may not transact as an Intermediary for any Customer 

unless the relevant Trading Privilege Holder has submitted a signed representation to NEX SEF 

that each of the Authorised Trading Firm's Customers is an "eligible contract participant" as defined 

in the Act and as an Eligible Counterparty.

(f) NEX SEF may (i) prevent a person from becoming an Authorised Trader or Authorised 

Trading Firm, and (ii) determine not to permit an Authorised Trader or Authorised Trading Firm to maintain 

its, his or her association with a Trading Privilege Holder or Authorised Trading Firm, as the case may be, 
24

if such Authorised Trader or Authorised Trading Firm causes or would cause NEX SEF to be in violation of 

Applicable Law.

Rule 203 Financial Integrity

(a) Each Trading Privilege Holder, Customer and Authorised Trading Firm must be an "eligible 

contract participant" as defined in the Act and a Professional Client or an Eligible Counterparty (i) prior to 

obtaining access to the Facility, and (ii) at the time that such person enters into each transaction on the 

Facility or subject to the Rules.

(b) For Cleared Contracts:

(1) each Trading Privilege Holder or Authorised Trading Firm transacting on the 

Facility as a principal is required to demonstrate to NEX SEF, with appropriate documentary 

evidence as required by NEX SEF from time to time, that such Trading Privilege Holder or 

Authorised Trading Firm is a Clearing Firm or that it has clearing arrangements in place with a 

Clearing Firm, including having the Clearing Firm Representation required by Rule 204 (f); and

(2) each Trading Privilege Holder and Authorised Trading Firm acting as an 

Intermediary shall confirm that each of its Customers has clearing arrangements in place with a 

Clearing Firm and obtain from its Customers any documentary evidence as required by NEX SEF 

from time to time to that effect, including any Clearing Firm Representation required by Rule 204 

(f). In either case, the Trading Privilege Holder shall provide such documentary evidence to NEX 

SEF.

(c) For Contracts listed on the Facility as bilateral Contracts, each Participant that enters into 

such Contracts as a principal must undergo such credit checks and provide such credit information as the 

Facility may require from time to time.

Rule 204 Clearing

(a) All Contracts executed on the Facility that are subject to mandatory clearing under 

Section 2(h) of the Act must be cleared through a DCO by a Clearing Firm. Any other Contracts executed 

on the Facility may be cleared at the discretion of the parties to such transaction; provided that such 

Contracts are able to be cleared through a DCO by a Clearing Firm. After being submitted to and accepted 

by the relevant DCO, each Cleared Contract will be subject to the rules, policies and procedures of such 

DCO.

(b) Pre-Execution Credit Check / Risk Screening.

(1) In advance of submitting each Bid/Offer or Pre-Arranged Cross to the Facility for 

any Cleared Contract, each Trading Privilege Holder or Authorised Trading Firm shall identify the 

Clearing Firm to which any resulting transaction will be submitted for clearing at the relevant DCO 

and:

(i) if acting as principal, shall ensure that it has sufficient credit with such 

Clearing Firm for the resulting transaction and that the resulting 

transaction satisfies such Clearing Firm's Risk-Based Limits; and

(ii) if acting as an Intermediary, shall confirm that its Customer has sufficient 

credit with the Customer's Clearing Firm for the resulting transaction and 

that the resulting transaction satisfies such Clearing Firm's Risk-Based 

Limits.

In the event that there is insufficient credit or the transaction does not satisfy a Clearing Firm's Risk-Based 

Limits, the Trading Privilege Holder or Authorised Trading Firm may not submit such Bid/Offer or 

Pre-Arranged Cross to the Facility.
25

(2) Each Clearing Firm that provides a Clearing Firm Representation for a Participant 

or Customer may notify NEX SEF of the Risk-Based Limits it has established for such Participant 

or Customer, and such Risk-Based Limits shall become effective upon acknowledgment of receipt 

by NEX SEF. Any change to such Risk-Based Limits shall become effective only upon 

acknowledgment of receipt by NEX SEF.

(c) A Clearing Firm that seeks to effect transactions on the Facility for its own account or the 

account of any Customer must be a Trading Privilege Holder.

(d) NEX SEF may share information with any DCO that would assist such DCO in evaluating 

and monitoring a Clearing Firm's compliance with these criteria. A Clearing Firm agrees to cooperate with 

NEX SEF and each relevant DCO in any such monitoring.

(e) Clearing Firms shall clear Cleared Contracts in accordance with all applicable Rules and 

DCO rules.

(f) Clearing Firm Representation

(1) Each Trading Privilege Holder or Authorised Trading Firm that is not a Clearing 

Firm and is transacting in Cleared Contracts on the Facility as a principal shall obtain a 

representation from a Clearing Firm, in form and substance satisfactory to, and approved by, NEX 

SEF (a "Clearing Firm Representation"). Under such representation, the Clearing Firm must 

accept for clearing all Cleared Contracts of each Trading Privilege Holder or Authorised Trading 

Firm for which it clears Cleared Contracts, subject to any Risk-Based Limits that are in effect 

pursuant to Rule 204(b)(2). Where a Trading Privilege Holder or Authorised Trading Firm uses the 

services of multiple Clearing Firms, a Clearing Firm shall be responsible only to the extent that it 

has been designated by such Trading Privilege Holder or Authorised Trading Firm to clear a 

particular Cleared Contract.

(2) Each Trading Privilege Holder and Authorised Trading Firm acting as Intermediary 

shall obtain from the Customer a Clearing Firm Representation from a Clearing Firm pursuant to 

which the Clearing Firm accepts for clearing all transactions in Cleared Contracts entered into by 

the Customer, subject to any Risk-Based Limits that are in effect pursuant to Rule 204(b)(2). Where 

a Customer uses the services of multiple Clearing Firms, a Clearing Firm shall be responsible only 

to the extent that it has been designated by such Customer to clear a particular Cleared Contract.

(3) Every Contract that is subject to a Clearing Firm Representation and results from 

a Bid/Offer or Pre-Arranged Cross that is within any Risk-Based Limits that are in effect pursuant 

to Rule 204(b)(2) is deemed accepted for clearing by the Clearing Firm upon execution.

(4) A Clearing Firm may at any time (but on prior written notice to NEX SEF) revoke 

any Clearing Firm Representation made by it to a Trading Privilege Holder, Authorised Trading 

Firm or Customer (as applicable) in accordance with paragraph (1) and/or (2) above, by providing 

prior written notice of such revocation to NEX SEF. The Clearing Firm Representation will remain 

in effect for all Contracts for which Bids/Offers or Pre-Arranged Crosses were submitted to a 

Trading Platform prior to NEX SEF's acknowledgment of the revocation, which NEX SEF shall 

undertake to effectuate as promptly as practicable.

(5) Each Trading Privilege Holder, Authorised Trading Firm or, if applicable, Customer 

must assist its Clearing Firm and the DCO in the clearing of its Cleared Contracts.

(6) Upon notice that a Clearing Firm has revoked any authorisation granted and 

Clearing Firm Representation made by it to a Trading Privilege Holder, Authorised Trading Firm or 

Customer pursuant to this Rule 204(f), the right of such Trading Privilege Holder, Authorised 

Trading Firm or Customer (as applicable) to enter into Cleared Contracts will be automatically 

terminated, and such Trading Privilege Holder, Authorised Trading Firm or Customer must obtain 

another Clearing Firm Representation from a Clearing Firm before the Trading Privilege Holder's, 
26

Authorised Trading Firm's or Customer's right to access to trade Cleared Contracts via the Facility 

will be reinstated.

(g) A DCO may be given access to the Facility for the purpose of obtaining any information 

required by the DCO to clear contracts, including, without limitation, real-time data regarding Bids/Offers, 

Pre-Arranged Crosses and the execution of transactions. NEX SEF may impose such restrictions on a 

DCO's access that it determines, in its sole discretion, are necessary and appropriate.

(h) Failure to Clear

(1) Subject to a Clearing Firm's obligation to accept for clearing all Contracts resulting 

from Bids/Offers or Pre-Arranged Crosses that satisfy the Risk-Based Limits in effect for a 

Participant or Customer, any Cleared Contract, including one leg of a Package Transaction, that is 

rejected for clearing by a Clearing Firm or DCO for any reason, including an error by NEX SEF in 

permitting a Bid/Offer or Pre-Arranged Cross to be made that did not satisfy the Risk-Based Limits 

in effect at the time the Bid/Offer or Pre-Arranged Cross was made, shall be void ab initio and will 

be cancelled by NEX SEF. For the avoidance of doubt, any component leg of a Package 

Transaction that was accepted for clearing will not be affected by the rejection of another leg of the 

same Package Transaction.

(2) Any Contract, including any component leg of a Package Transaction, that was 

executed on the Facility without the intent to be cleared, but later determined by the parties to the 

transaction to be cleared, will not be void if rejected for clearing by a DCO to which the Contract or 

component leg of the Package Transaction was submitted.

(3) In the event a Cleared Contract, including one leg of a Package Transaction, is 

cancelled by NEX SEF pursuant to this Rule 204(h), NEX SEF will report such cancellation to the 

relevant SDR pursuant to Part 43 of the Commission Regulations.

(4) Any transaction cancelled under this Rule 204(h) (except for transactions rejected 

by a DCO for credit reasons) may be re-executed pursuant to the procedures set forth in Rule 

315(i).

(i) Submission of Cleared Contracts to DCOs

(1) NEX SEF shall route each Cleared Contract executed on the Facility and accepted 

for clearing by a Clearing Firm to the DCO identified pursuant to Rule 208(d) as soon as 

technologically practicable after execution, and in no event later than ten (10) minutes after 

execution. NEX SEF may do so either by submitting the Cleared Contract directly to the DCO or 

by routing the Cleared Contract through an Affirmation Hub.

(2) Cleared Contracts that are routed through an Affirmation Hub shall be routed in 

accordance with the following procedures:

(i) All Cleared Contracts executed as Pre-Arranged Crosses or on the Order 

Book with the assistance of a NEX SEF customer service representative, 

must be Affirmed by Participants or Customers, as applicable, as soon as 

technologically practicable after execution, and in no event later than ten 

(10) minutes after execution; and

(ii) All other Cleared Contracts shall be automatically submitted by the 

Affirmation Hub to the relevant DCO as soon as technologically practicable 

after receipt from NEX SEF, without Participants or Customers being 

provided the opportunity to Affirm.
27

(3) Failure by a Participant or Customer to Affirm a Cleared Contract routed through 

an Affirmation Hub within the ten (10) minute time frame required by this Rule 204(i) shall be a 

Violation; provided that:

(i) such failure shall be a Violation only by the Participant(s) or Customer(s), 

as applicable, that failed to Affirm the Cleared Contract in accordance with 

this Rule; and

(ii) no such failure shall be a Violation where the failure was substantially the 

result of, as determined in NEX SEF's discretion, any errors or delays 

caused by NEX SEF or any customer service representative.

(4) The Compliance Function or a designated member of the Market Regulation Staff 

shall, on a monthly basis, review the previous month's Affirmations by Participants and Customers 

for compliance with this Rule 204(i). Notwithstanding such regular monthly reviews, the 

Compliance Function or any member of the Market Regulation Staff may investigate possible 

Violations of this Rule 204(i) at any time upon becoming aware of such possible Violation. 

Investigations of possible Violations of this Rule 204(i) shall be conducted in accordance with 502, 

including that the Compliance Function may determine to impose summary fines in accordance 

with Rule 516. The Compliance Function or a designated member of the Market Regulation Staff 

shall review each possible Violation of this Rule 204(i) in light of all the facts and circumstances, 

including whether any errors or delays were caused by NEX SEF or any customer service 

representative.

(j) Breakage Agreements Prohibited. Participants and Customers are prohibited from 

requiring a Breakage Agreement from any other Participant or Customer as a condition of trading with that 

other Participant or Customer.

Rule 205 Application for and Grant of Trading Privileges; Access Denial Actions

(a) Application Requirement. Each applicant for Trading Privileges will submit an application 

to NEX SEF in a form and manner prescribed by NEX SEF. Each applicant will promptly update the 

application materials if any of the information provided therein becomes inaccurate or incomplete after the 

date of submission and prior to any approval of the application. NEX SEF will act upon, and approve or 

disapprove, any such application without unreasonable delay.

(b) Due Diligence Review. Prior to granting Trading Privileges, NEX SEF will conduct a due 

diligence process against the conditions for using the Facility as described in a MRAN available on NEX 

SEF's website. 

(c) Grant of Trading Privileges. Upon submission of an application and satisfaction of the 

requirements and procedures set forth in this Chapter 2, and approval by NEX SEF, a person applying for 

Trading Privileges will be granted Trading Privileges. If the application process is not completed by the 

applicant within six months of submission of an application and payment of any applicable fee, the 

application will be deemed to be withdrawn.

(d) Denial of Trading Privileges. If NEX SEF disapproves an application for Trading Privileges, 

NEX SEF will promptly provide notice of such rejection. Any applicant who has been denied Trading 

Privileges or Authorised Trader or Authorised Trading Firm status with a Trading Privilege Holder, and any 

Trading Privilege Holder or Authorised Trader or Authorised Trading Firm of a Trading Privilege Holder who 

is not permitted to keep its, his or her Trading Privileges or maintain his, her or its status as an Authorised 

Trader or Authorised Trading Firm may request an appeal of NEX SEF's decision pursuant to the 

procedures set forth in Rule 205(f). If no request for an appeal is made within seven days after receiving 

notice of the disapproval of the relevant application or suspension or termination of access to NEX SEF, 

the disapproval, suspension or termination shall be the final determination of NEX SEF. No determination 

of NEX SEF to discontinue a person's Trading Privileges or Authorised Trader or Authorised Trading Firm 
28

status will take effect until the review procedures hereunder have been exhausted or the time for review 

has expired.

(e) Re-application. Any applicant to become a Trading Privilege Holder who has been denied 

Trading Privileges pursuant to this Rule 204(a) will not be eligible for re-application during the six months 

immediately following such denial.

(f) Appeal of Denial of Trading Privileges or Suspension or Termination of Access

(1) If NEX SEF, pursuant to this Rule, denies an application for Trading Privileges or 

association with a Trading Privilege Holder as an Authorised Trader or Authorised Trading Firm, or 

determines not to permit a person to keep its Trading Privileges or maintain its association as an 

Authorised Trader or Authorised Trading Firm, or suspends or revokes a Participant's or 

Customer's access to the Facility pursuant to Rule 206(c) or (g), then, in any such case, the affected 

applicant, Trading Privilege Holder, Authorised Trader, Authorised Trading Firm, Participant or 

Customer, as the case may be, within seven days after receiving written notice of such decision, 

may request in writing that NEX SEF provide the reasons therefor in writing. Within 14 days of 

receiving any such written request, NEX SEF will provide the applicant, Trading Privilege Holder, 

Authorised Trader, Authorised Trading Firm, Participant or Customer, as the case may be, with 

such reasons in writing. Within 14 days of receiving NEX SEF's written response, the applicant, 

Trading Privilege Holder, Authorised Trader, Authorised Trading Firm, Participant or Customer, as 

the case may be, may request, in writing, that the Participation Committee reconsider NEX SEF's 

initial decision and may provide any written representations or other information that the applicant, 

Trading Privilege Holder, Authorised Trader, Authorised Trading Firm, Participant or Customer, as 

the case may be, believes is relevant to the reconsideration.

(2) Within 28 days of receiving either a written request for reconsideration or written 

representations or information from the applicant, Trading Privilege Holder, Authorised Trader, 

Authorised Trading Firm, Participant or Customer, as the case may be, or a statement from such 

person that no such representation or information is to be made or supplied, the Participation 

Committee will either confirm, reverse or modify the initial decision and will promptly notify the 

applicant, Trading Privilege Holder, Authorised Trader, Authorised Trading Firm, Participant or 

Customer, as the case may be, accordingly. The Participation Committee may in its discretion 

schedule a hearing or establish any other process that it believes is necessary and appropriate to 

consider the request for reconsideration. Any decision by the Participation Committee pursuant to 

this subparagraph (2) constitutes the final action of NEX SEF with respect to the matter in question 

and is not subject to appeal. 

(3) Any action that may be taken by the Participation Committee under this Rule 205(f)

or (g) may be taken by the Board if no Participation Committee has been established.

(g) Effective Date of Denial of Trading Privileges or Suspension or Termination of Access

(1) If NEX SEF makes a final determination to deny an application for Trading 

Privileges or association with a Trading Privilege Holder as an Authorised Trader or Authorised 

Trading Firm, or determines not to permit a person to keep its Trading Privileges or maintain its 

association as an Authorised Trader or Authorised Trading Firm pursuant to Rule 205(d) or (f), or 

suspends or revokes a Participant's or Customer's access to NEX SEF pursuant to Rule 206(c) or 

(g), then the Participation Committee (or Board acting in such capacity) shall provide written notice 

within thirty (30) days of its determination to the applicant, Participant or Customer, as applicable. 

The written notice must include the information required by Part 9 of the Commission Regulations. 

Unless otherwise determined by NEX SEF in accordance with Part 9 of the Commission

such capacity) reasons for the denial of Trading Privileges, suspension or

Contracts involved, if any, and a listing of any Rules the Participation 

Committee determined were Violated and whether the Violation resulted 

in any financial harm to Customers;

(or Board acting in such capacity) with respect to each Violation, or, in the 

event of a settlement, a statement specifying the alleged Violations;

access to NEX SEF;

Background Affiliation Status Information Center ("BASIC").

(3) Any decision by NEX SEF to deny Trading Privileges or to suspend or revoke 

access to NEX SEF pursuant to this Rule shall be the final decision of NEX SEF and shall become 

effective in accordance with the timeline set forth in Rule 513(b).

(4) If NEX SEF denies Trading Privileges or suspends or revokes access to the Facility

pursuant to this Rule, it must publicly publish and maintain on its website the information contained 

in the written notice provided pursuant to Rule 205(g)(1). 

Rule 206 Participant and Customer Obligations; Suspension or Termination of Access

(a) Consent to Facility Rules. Prior to obtaining access to the Facility and each time a 

Participant or Customer initiates or executes a transaction on the Facility, directly or through an 

Intermediary, each Participant or Customer shall be deemed to have expressly consented to the jurisdiction 

of the Facility and agreed to be bound by and comply with the Rules. At the time any Clearing Firm provides 

a Clearing Firm Representation, each such Clearing Firm shall expressly consent to the jurisdiction of the 

Facility and agree to be bound by and comply with the Rules.

(b) NEX SEF shall perform an annual risk-based assessment of the compliance by each 

Participant and Customer with these Rules. Where necessary, NEX SEF shall undertake additional 

assessments of compliance by a Participant or Customer. 

(c) Each Participant and Customer must comply with these Rules and the provisions of 

Applicable Law. Each Participant and Customer must also cooperate promptly and fully with NEX SEF, its 

agents, its Regulatory Services Provider, and/or a Regulatory Agency in any due diligence process, 

assessment, investigation, call for information, inquiry, audit, examination, or proceeding. Such 

cooperation shall include a duty to provide supplemental verbal or other information if the Participant or

Customer learns that a previous response is incomplete or incorrect in any material respect. Additionally, 

each Trading Privilege Holder must update its email address promptly after any change and update all 

other material information provided in its application for Trading Privileges within five days after that 

information has changed. If any Participant or Customer fails to satisfy these obligations, NEX SEF may 
30

revoke or suspend the Participant's or Customer's access to the Facility in full or in part, including by 

revoking or suspending the access to the Facility of a specific Automated Trading System.

(d) Each Participant and Customer consents to allow NEX SEF to provide all information NEX 

SEF has about the Participant or Customer, including the Participant's or Customer's trading activity, to the 

Regulatory Services Provider, the Commission or any other Regulatory Agency, law enforcement authority, 

or judicial tribunal, including (as may be required by information sharing agreements or other contractual, 

regulatory, or legal provisions) foreign regulatory or self-regulatory bodies, law enforcement authorities, 

judicial tribunals and any other service provider to NEX SEF solely in connection with the service provider's 

performance of services to NEX SEF and subject to the service provider's agreeing to maintain such 

information as confidential, including that such service provider shall not:

(1) use such information for any purpose other than in connection with providing 

services to the Facility (including that it may not otherwise use such information for its own business 

or marketing purposes), unless specifically required in order to fulfill such service provider's 

regulatory obligations; or 

(2) disclose such information to any other person, except (i) to its employees or 

Affiliates, provided that the employees or Affiliates are subject to confidentiality obligations at least 

as stringent as those applicable to the service provider, and that, in each case, such disclosure is 

necessary for the performance of services to the Facility by the service provider, or (ii) if compelled 

to do so by valid legal or regulatory process, provided that the service provider notifies NEX SEF 

in advance thereof to the extent permitted. 

(e) Each Participant is required to review the "Notices" section of the Facility's website to make 

itself aware of material changes to these Rules or other notices (including MRANs) that may affect their 

rights and obligations as a Participant.

(f) Each Trading Privilege Holder must diligently supervise all activities of the Trading Privilege 

Holder's employees and/or agents, including all Authorised Traders and Authorised Trading Firms relating 

to transactions effected on the Facility. Any Violation by any employee of a Trading Privilege Holder, 

including an Authorised Trader or Authorised Trading Firm, shall constitute a Violation by such Trading 

Privilege Holder.

(g) NEX SEF may revoke or suspend a Participant's access to the Facility in full or in part if 

the Participant acts as an Intermediary on behalf of a Customer and such Customer maintains a position in 

any Contract that, when considered in light of the other positions maintained by the Participant through 

which such Customer accesses the Facility, and any other factors that NEX SEF reasonably deems 

relevant, NEX SEF reasonably believes could jeopardise the financial safety of such Participant or any of 

such Participant's Customers. In making this determination, NEX SEF may consider any relevant factors, 

including, as applicable, (i) the positions maintained by such Participant, such Participant's Authorised 

Traders, Authorised Trading Firms and Customers, (ii) financial information provided by such Participant; 

and (iii) in consultation and coordination with the relevant DCOs, the level of margin maintained by such 

Participant at such Participant's Clearing Firm.

(h) Each Participant must undertake conformance tests within the NEX SEF testing 

environment to ensure that the basic functioning of the Participant's trading system (including any 

Automated Trading System), algorithm and strategy complies with these Rules prior to the deployment, or 

a substantial update of:

(1) the access to the Facility; or

(2) the Participant's trading system (including any Automated Trading System), 

trading algorithm or trading strategy.

The conformance testing shall verify the following: 
31

(1) the ability of the system or algorithm to interact as expected with the Facility's 

matching logic and the adequate processing of the data flows from and to the Facility; 

(2) the basic functionalities such as submission, modification or cancellation of an 

order or an indication of interest, static and market data downloads and all business data flows; 

and

each Trading Privilege Holder to become aware of and familiar with, and to implement any necessary 

preparatory measures to be taken by it with respect to, such addition or modification, prior to the effective

assessments or fees to be levied on Trading Privilege Holders, which dues, assessments or fees will be

comparable for Trading Privilege Holders receiving comparable access to, or services from, NEX SEF.

fees levied on such Trading Privilege Holder, and such payment obligation remains unsatisfied thirty

Privileges of such Trading Privilege Holder as it deems necessary or appropriate.

Rule 212 Market Maker Programs

(a) NEX SEF may from time to time adopt one or more programs under which one or more 

Trading Privilege Holders or others may be approved and designated as market makers with respect to one 
36

or more Contracts in order to provide liquidity and orderliness in the market or markets for such Contract or 

Contracts. Any such program may provide for any or all of the following:

(1) qualifications, including any minimum net capital requirements, that any such

making strategy" by way of algorithmic trading on the Facility will be deemed to have accepted the terms 

of the "Market Making Agreement between NEX SEF Limited and Market Makers on the NEX SEF" that is 

available on the Facility's website (the "MMA", which is a Market Maker Programme), where (in accordance 

with article 1(1) of the Market Making CDR), during half the Trading Days over a one month period, in 

execution of its market making strategy, they:

(1) post Firm, Simultaneous Two-Way Quotes of Comparable Size and Competitive 

Prices; and

(2) deal on their own account in at least one Instrument for at least 50% of the daily 

trading hours of continuous trading on the Facility, excluding opening and closing auctions.

(c) Capitalised terms used in Rule 212(b) that are not otherwise defined in this Rulebook have 

the meaning given to them in the MMA (and for the purposes of Rule 212(b), to the extent of any

Rule 213 Independent Software Vendors

NEX SEF shall provide impartial access to independent software vendors who enter into a development 

and maintenance agreement with NEX SEF (an "ISV Development and Maintenance Agreement"). Fees 

will be comparable for independent software vendors receiving comparable access to, or services from, 

NEX SEF. Each independent software vendor that enters into an ISV Development and Maintenance 

Agreement must satisfy the following criteria, which NEX SEF shall apply in a fair and non discriminatory 

manner:

(a) if required to be registered in any capacity under Applicable Law, it has duly registered in 

such capacity and such registration is in effect and has not lapsed or been revoked, suspended or 

withdrawn;

(b) it complies with the applicable technical access standards, system compatibility 

requirements, security protocols and technical specifications for connection to NEX SEF's electronic 

systems as may be specified by NEX SEF from time to time;
37

(c) it must ensure that each person that uses the independent software vendors to access the 

Facility is a Participant or a Customer of a Participant authorised as such in accordance with these Rules;

(d) it may provide data obtained from the Facility solely to such Participants or Customers of 

Participants in connection with their actual and proposed trading activity in Contracts and similar contracts, 

and shall not provide such data to any other SEF, security-based swap execution facility, designated 

contract market, national securities exchange or other trading facility or system without the prior written 

consent of NEX SEF;

(e) in the case of any Bid/Offer submitted to NEX SEF through an independent software 

vendor, the independent software vendor will provide sufficient detail to identify the Participant (and, in the 

case of an Intermediated Transaction, the Intermediary and Customer) as required by NEX SEF; and

(f) it satisfies such other impartial and transparent criteria as NEX SEF may specify from time 

to time, subject to Applicable Law. 

Rule 214 Withdrawal of Participant

(a) To withdraw from the Facility, a Participant must notify NEX SEF in writing, following such 

procedures as may be established by NEX SEF.

(b) NEX SEF may, in its reasonable discretion, refuse to accept a Participant's withdrawal

request or may postpone the effective date of withdrawal of a Participant if NEX SEF considers it necessary 

for the protection of the Participant's Customers, other Participants or otherwise in the interests of NEX 

SEF.

(c) Based on the information provided to, and other information gathered by, NEX SEF 

regarding a Participant's withdrawal request, NEX SEF will determine whether to: (i) accept the withdrawal 

request; (ii) postpone the effective date of the withdrawal; or (iii) impose any terms or conditions before or 

after the effective date of withdrawal.

(d) If NEX SEF refuses to accept a Participant's withdrawal request or postpones the effective 

date of withdrawal of a Participant, NEX SEF may waive the obligation to pay some or all of the fees, costs 

and charges that NEX SEF would have imposed during the period after the date on which the requested 

withdrawal would have otherwise taken effect.

(e) When NEX SEF accepts the withdrawal of a Participant, all rights and privileges of such 

Participant terminate (including the Trading Privileges and ability to access a Trading Platform). The 

accepted withdrawal of a Participant shall not affect the rights of NEX SEF under the Rules or relieve the 

former Participant of its obligations with respect to previously executed transactions (including any 

contractual obligations relating to any Contracts entered into by such Participant, or the payment of any 

fees, costs, or charges incurred prior to such withdrawal). Notwithstanding the accepted withdrawal of a 

Participant, the withdrawn Participant remains subject to the jurisdiction of the Facility for acts done and 

omissions made while a Participant, and must cooperate in any proceeding under Chapter 5 as if such 

withdrawal had not taken place.

(f) Upon delivery of a withdrawal notice:

(1) the Participant shall promptly notify its Authorised Traders and Authorised Trading 

Firms that they may no longer access the Facility on behalf of such Participant, and the Participant 

shall with reasonable diligence, to the extent practicable, terminate electronic access of its 

Authorised Traders and Authorised Trading Firms to the Facility; and

(2) NEX SEF shall suspend the Participant's access to the Facility, promptly notify its 

relevant personnel that Participant and its Authorised Trading Firms may no longer access the 

Facility on behalf of such Participant, and with reasonable diligence, to the extent practicable, 

terminate electronic access of the Participant's Authorised Traders to the Facility.

Limits shall become effective upon acknowledgment of receipt by the Facility. Any change to such 

Prime Broker Limits shall become effective only upon acknowledgment of receipt by the Facility. 

(3) Revocation of Prime Broker Representation. A Prime Broker may revoke any 

Prime Broker Representation at any time by providing prior written notice of such revocation to the

CHAPTER 3

TRADING PROCEDURES

Rule 301 Trading Sessions

Except as otherwise provided in these Rules or determined by the Board, transactions in any Contract will 

only be executed during the Trading Session for such Contract. NEX SEF may from time to time modify its 

regular Trading Session and establish Trading Sessions, in addition to the regular Trading Sessions, as it 

deems appropriate.

Rule 302 Information about, and access to, NEX SEF's Order Book

(a) User Identifications and Passwords

(1) Each Authorised Trader and each Trading Privilege Holder that is an individual will 

receive a user identification ("ID") and password. As a Trading Privilege Holder or Authorised 

Trader, such person will be able to access NEX SEF's Order Book, which functions as an electronic 

central limit order book and provides the highest priority to Bids/Offers with the best price, for trading 

in the Swap asset classes or sub-products approved for such Trading Privilege Holder or 

Authorised Trader, enter and accept Bids/Offers, and otherwise access information regarding, or 

perform functions for, such person's account using its ID and password. 

(2) Each ID shall represent an Authorized Trader that is:

(i) a natural person physically responsible for manually accessing an Order 

Book through either (A) NEX SEF’s web-based portal or (B) a NEX SEF 

work station; or

(ii) an ATS Operator of an Automated Trading System accessing an Order 

Book through an API.

(3) Each ID issued:

(i) for a natural person manually accessing an Order Book may only be used 

by that natural person and may not be used by any other natural person 

or entity and may not be used as the ID for an Automated Trading System; 

and

(ii) for an ATS Operator of an Automated Trading System may only be used 

by that ATS Operator for a single Automated Trading System and may not 

be used for any other Automated Trading System and may not be used as 

the ID for any other natural person or entity. An ATS Operator that 

operates multiple Automated Trading Systems must obtain a separate and 

unique ID for each Automated Trading System that the ATS Operator 

operates.

(4) For an ATS Operator that consists of an ATS Team, the Trading Privilege Holder 

or Authorised Trading Firm of such ATS Operator, as the case may be, shall collect and maintain 

accurate, complete and up-to-date records for the ATS Operator’s ID, including the time period that 

each natural person was monitoring the Automated Trading System.

(5) Each Trading Privilege Holder will be responsible for protecting from improper 

disclosure its ID and password, and the IDs and passwords of its Authorised Traders. In addition, 

a Trading Privilege Holder may not knowingly or negligently permit any person not authorised by 

NEX SEF and by the Trading Privilege Holder to use the ID and password to access the Order 

Book. Each Trading Privilege Holder is required to immediately notify NEX SEF if it knows, or has 
41

reason to believe, that its ID and/or password, or the ID and/or password of any Authorised Trader 

have been disclosed to any person not authorised by NEX SEF and the Trading Privilege Holder 

to use such ID and/or password. 

(6) Except as otherwise provided in Rule 102: 

(i) each Trading Privilege Holder will be liable for all costs and any losses that 

it may incur from transactions executed on the Facility by any person, 

authorised or not, using its ID and password or the ID and/or password of 

any of its Authorised Traders; and

(ii) NEX SEF will not be responsible in any way for unauthorised transactions 

for a Trading Privilege Holder's account.

(b) For account security and audit trail purposes, each Trading Privilege Holder and Authorised 

Trader agrees that NEX SEF may maintain logs of the IP address used to log on to any Order Book.

(c) Each Trading Privilege Holder is responsible for contracting with a network provider 

through which it will access the Facility and for having a backup service provider if the Trading Privilege 

Holder deems it necessary. Each Trading Privilege Holder is also responsible for maintaining a network 

connection speed adequate for its needs. NEX SEF will not be responsible in any way for any Bids/Offers 

delayed or transactions missed or not executed in a timely fashion because of failure of the Trading Privilege 

Holder's Internet service provider or slowness of its network connection speed. No communication from a 

Trading Privilege Holder will be deemed to have been received by NEX SEF until that communication is 

logged by the Order Book server.

Rule 303 Required Transactions

NEX SEF does not currently offer any Contracts that are Required Transactions. Accordingly, NEX SEF 

does not currently offer RFQ functionality. 

Rule 304 Permitted Transactions

(a) Participants may enter Bids/Offers for Permitted Transactions directly into the Facility's 

Order Book for that Contract. 

(b) Participants may submit to the Facility's pre-arranged crossing Trading Platform for 

execution Permitted Transactions negotiated and agreed to outside the Facility's Order Book, at prices 

mutually agreed, with regard to Contracts that have been designated by NEX SEF for such purpose (each 

such transaction a "Pre-Arranged Cross"). Pre-Arranged Crosses that are submitted to the Trading 

Platform for execution must be submitted by the seller, unless otherwise agreed to by the parties; however, 

in the case of an Intermediated Transaction, the Participant acting as the Intermediary shall have the 

obligation to submit the Pre-Arranged Cross to the Trading Platform. The Participant submitting the 

Pre-Arranged Cross to the Trading Platform must provide the information required by Rule 208(d).

(c) A NEX SEF customer service representative may facilitate the negotiation and execution 

of a Pre-Arranged Cross by two Participants only as follows: upon request of a Participant, the customer 

service representative may, without using any Trading Platform or Order Book, contact one or more other 

Participants to determine interest in a Pre-Arranged Cross. 

(d) Upon execution of the Permitted Transaction on the Facility, NEX SEF will report the 

transaction to the SDR as soon as technologically practicable after execution in accordance with Rule 309.

(e) Each Participant that is party to, or Intermediary in, a Pre-Arranged Cross executed 

pursuant to section (b) of this Rule 304 must record the following details of the transaction: the Contract 

(including the Delivery Month) to which such transaction relates; the number of Contracts traded; the price 

of execution or premium; the identity of the counterparty; and, if applicable, details regarding the Customer 
42

for which the transaction was executed, as well as, if applicable, the Underlying Interest and whether the 

transaction involved a put or a call and the strike price. Upon request by NEX SEF, such Participant must 

produce satisfactory evidence, including the transaction information referred to in the preceding sentence

for which each transaction is executed, including whether the Participant or Customer executed the 

transaction for its own account or the transaction was executed by an Intermediary; (iii) timing and 

sequencing data adequate to reconstruct trading; and (iv) subject to Rule 309(h), identification of each 

Participant or Customer to which fills are allocated.

(d) NEX SEF will use the electronic transaction history database to reconstruct trading and 

identify possible Violations. In furtherance of Applicable Law, NEX SEF will conduct an annual review of 

compliance by all Participants and Customers that are responsible for, or in control of, the creation of audit 

trail records with its audit trail and recordkeeping requirements and will identify Participants and Customers

that may have failed to comply with such requirements. Such Participants and Customers will be subject 

to investigation by the Market Regulation Staff for possible disciplinary action. The annual review must 

include, but is not limited to, reviews of randomly-selected samples of front end audit trail data for order 

routing systems; a review of the process by which user identifications are assigned and user identification 

records are maintained; a review of usage patterns associated with user identifications to monitor for 

violations of user identification Rules; and reviews of account numbers and Customer Type Indicator Codes 

in transaction records to test for accuracy and improper use.

(e) All such information will be maintained by NEX SEF in a manner that protects it from 

unauthorised alteration, as well as from accidental erasure or other loss.

(f) NEX SEF will publish trading information as required by:

(1) Core Principle 9, Commission Regulation § 37.901 and Part 16 of the Commission 

Regulations; and 

(2) FCA rules and MiFIR. 
43

Under certain conditions, the FCA may grant a trading venue permission not to make public current 

Bid and Offer prices for a Contract and the depth of trading interest at those prices (a "Waiver"). 

NEX SEF will notify Participants of any such Waiver obtained from the FCA.

(g) Reporting to SDRs

(1) NEX SEF will report all transactions in Contracts executed on the Facility or 

pursuant to the Rules to an SDR of NEX SEF's choice as soon as technologically practicable after 

the execution of such transaction. NEX SEF will report such transactions as set forth below:

(i) For Cleared Contracts, including all legs of a Package Transaction, in all 

asset classes: NEX SEF reports to DTCC. 

(ii) For Non-Cleared Contracts, including all legs of a Package Transaction, 

in all asset classes: NEX SEF reports to DTCC. 

(2) As soon as technologically practicable after the execution of a Contract, NEX SEF 

will report to both counterparties and to the DCO, if any, that will clear the Contract: (i) the identity 

of the SDR to which the Contract was reported; and (ii) the Contract's unique Swap identifier.

(3) All real-time data required by Part 43 of the Commission Regulations and all 

creation data, including primary economic terms and confirmation data, required by Part 45 of the 

Commission Regulations will be reported to the relevant SDR as provided for under Part 43 and 

Part 45 of the Commission Regulations. 

(4) NEX SEF will disseminate swap transaction and pricing data relating to Contracts 

to Participants no earlier than the transmittal of such information to the relevant registered SDR.

(5) After becoming aware of or being notified of any errors or omissions in the 

transaction or pricing data set forth in a Confirmation by a Participant pursuant to Rule 312(d), the 

Facility shall then promptly submit corrected data to the relevant SDR.

(6) Neither the Facility nor any Participant may submit or agree to submit a cancelation 

or correction for the purposes of re-reporting Swap transaction and pricing data in order to gain or 

extend a delay in public dissemination of accurate Swap transaction or pricing data or to otherwise 

evade the reporting requirements of Part 43 of the CFTC Regulations.

(h) Post Trade Allocations

(1) In reliance on NAL 17-54, expiring November 15, 2020, NEX SEF will not capture 

post-trade allocations in its audit trail data or conduct associated audit trail reviews of post-trade 

allocations.

(2) Each Participant and Customer shall provide NEX SEF post-trade allocation 

information to the SEF upon the request of NEX SEF.

(3) During the course of any trade practice surveillance or market surveillance 

investigation into any trading activity involving post-trade allocations, upon the request of the CFTC 

or otherwise, NEX SEF shall ascertain whether a post-trade allocation was made. Upon 

determining that such an allocation was made, NEX SEF shall request, obtain and review the 

post-trade allocation information as part of its investigation.

Rule 310 Bid/Offer Cancellation

(a) A Participant can submit instructions to either cancel or modify a Bid/Offer which that 

Participant has placed on the Facility if that Bid/Offer has not yet been accepted. Upon receipt of 

instructions to cancel a Bid/Offer that has not been executed, a Trading Platform will withdraw the Bid/Offer 
44

and confirm the cancellation of the Bid/Offer. If a Participant modifies a Bid/Offer that has not been 

executed, NEX SEF will treat the modified Bid/Offer as a new Bid/Offer.

(b) NEX SEF will attempt to cancel or modify an existing Bid/Offer after a Participant enters a 

cancellation or modification instruction. However, the Bid/Offer may be executed before NEX SEF is able 

to cancel or modify it. If a Bid/Offer has been filled in whole or in part, a Participant may modify or cancel 

only that portion of the Bid/Offer (if any) that has not been executed. Once cancelled by NEX SEF, a 

Bid/Offer will not be executed.

(c) NEX SEF shall automatically reject Bids/Offers which exceed pre-determined volume and 

price thresholds or are clearly erroneous ("Pre-Trade Controls"). Further details on the Pre-Trade Controls 

are provided by means of a MRAN available on NEX SEF's website. Any further detail on the Pre-Trade 

Controls shall be communicated to Trading Privilege Holders by means of an additional MRAN.

(d) NEX SEF may cancel unexecuted Bid/Offer in the following circumstances:

(1) upon request of a Participant where the Participant is technically unable to delete 

its own Bids/Offers or Bids/Offers it submitted on behalf of a Customer;

(2) where the Order Book contains erroneous duplicated Bids/Offers; and

(3) following a suspension of trading on the Facility initiated either by NEX SEF or by 

a Competent Authority. 

NEX SEF shall ensure that when cancelling unexecuted Bids/Offers in accordance with this Rule 310 (d), 

it acts in accordance with the Kill Functionality Policy.

(e) Each Participant shall be able to cancel immediately, as an emergency measure, any or 

all of its unexecuted Bids/Offers submitted to the Facility, including Bids/Offers it submitted on behalf of a 

Customer. 

(f) Upon suspension or revocation of a Participant's trading privileges by NEX SEF, any 

unaccepted Bid/Offer on the Facility for such Participant shall be cancelled by NEX SEF.

Rule 311 [Reserved]

Rule 312 Enforceability of Transactions

(a) Settlement

(1) Each Participant or, where a transaction is on behalf of a Customer, the relevant 

Customer, is obligated to settle all transactions executed, pursuant to the Rules in this Chapter 3.

(2) A transaction executed on the Facility or subject to the Rules shall not be void, 

voidable, subject to rescission, otherwise invalidated or rendered unenforceable as a result of:

(i) a violation by the Facility of Section 5h of the Act or Part 37 of the 

Commission Regulations;

(ii) any Commission proceeding to alter or supplement a rule, term or 

condition under Section 8a(7) of the Act or to declare an emergency under 

Section 8a(9) of the Act; or

(iii) any other proceeding the effect of which is to: (A) alter or supplement a 

specific term or condition or trading rule or procedures; or (B) require the 

Facility to adopt a specific term or condition, trading rule or procedure, or 

to take or refrain from taking a specific action.
45

(b) Issuance of Facility Confirmations for Cleared Contracts. Participants and Customers are 

obligated to submit for clearing all Contracts so required by the Act, Commission Regulations and any other 

applicable law. For Cleared Contracts, NEX SEF will provide the Trading Privilege Holder a Confirmation 

of all the terms of each transaction executed on the Facility at the time of execution; provided that where a 

Trading Privilege Holder is a Customer in an Intermediated Transaction, the confirmation will be provided 

to the Intermediary in accordance with Rule 313 (c). The Confirmation provided by NEX SEF for Cleared 

Contracts will be the final legally binding confirmation of the terms of any transaction executed on the Facility 

and will supersede any conflicting confirmation or agreement provided to, or between, as applicable, 

Participants and Customers, regardless of when such other confirmation is provided.

(c) Issuance of Facility Confirmations for Uncleared Transactions

(1) With respect to an uncleared transaction, the Facility will issue to each applicable 

Participant and/or Customer a written communication when a transaction is executed on the Facility 

which will serve as the Confirmation for the transaction. The Confirmation will contain the economic 

terms specific to the transaction agreed by each Participant on the Facility and it will incorporate 

by reference the documents and agreements (including, without limitation, ISDA master 

agreements, other master agreements, terms supplements, master confirmation agreements, and 

incorporated industry definitions) governing such transaction existing at the time of such 

commitment to which each Participant and/or Customer are party (the "Terms Incorporated by 

Reference").

(2) In satisfaction of the obligations imposed on NEX SEF under Commission 

Regulation 37.6(b), (i) each Confirmation is deemed to incorporate the Terms Incorporated by 

Reference set forth in this Rule 312(b) upon issuance of the Confirmation, (ii) each Participant and 

Customer hereby agrees that the provisions of Rule 312(c)(3) shall govern any conflicting terms, 

and (iii) the resulting Confirmation takes place at the time of execution of, and contains all the terms 

of, the transaction.

(3) In the event of any conflict between (x) the Confirmation and (y) the Terms 

Incorporated by Reference, the Confirmation shall prevail to the extent of any inconsistency and 

each Confirmation shall state the same.

(4) In accordance with NAL 17-17, expiring on the effective date of any changes in 

Commission Regulation 37.6(b), upon the request of NEX SEF, each Participant and Customer 

shall provide copies of the Terms Incorporated by Reference to NEX SEF.

(5) In accordance with NAL 17-17, expiring on the effective date of any changes in 

Commission Regulation 37.6(b), upon the request of the Commission, NEX SEF shall request the 

Terms Incorporated by Reference from the relevant Participant or Customer and shall provide such 

Terms Incorporated by Reference to the Commission as soon as possible after receipt from the 

Participant or Customer. 

(d) Review of Confirmations. Each Participant shall review the contents of each Confirmation 

issued to it pursuant to this Rule 312 and shall promptly report any errors or omissions in the transaction or 

pricing data therein to the counterparty to the Contract. Each Participant that is the reporting counterparty 

for such Contract, as determined pursuant to Rule 316, shall report all such errors or omissions to the 

Facility as soon as technologically practicable after becoming aware of the errors or omissions. 

Rule 313 Intermediated Transactions

(a) Participants who are Intermediaries shall immediately submit all Orders to the Facility to 

be immediately entered into a Trading Platform and shall immediately submit all Pre-Arranged Crosses to 

the Facility. If an Order or Pre-Arranged Cross cannot be immediately entered into a Trading Platform or 

submitted to the Facility, as applicable, an electronic record which includes the account identifier that relates 

to the account owner, time of receipt, and terms of the Order or Pre-Arranged Cross must immediately be 
46

created, and the Order or Pre-Arranged Cross must be entered into a Trading Platform or submitted to the 

Facility, as applicable, as soon as practicable.

(b) Priority of execution. Non-discretionary executable Customer Orders received by a 

Participant who is an Intermediary shall be entered into Facility in the sequence received. Non-discretionary 

Orders that cannot be immediately entered must be entered when the Orders become executable, in the 

sequence in which the Orders were received. 

(c) NEX SEF shall provide all Confirmations of Intermediated Transactions to the Intermediary 

upon execution of the transaction. Except to the extent that NEX SEF sends Confirmations of Contracts 

directly to the relevant Customer, any Participant that transacts as an Intermediary for any Customer shall 

be responsible for ensuring that such Customers receive all Confirmations of Contracts entered into on 

behalf of such Customers as soon as technologically practicable after receipt of the Confirmation from NEX 

SEF.

Rule 314 Bunched Orders

Bunched Orders must be allocated and recorded in accordance with Commission Regulation 1.35(b)(5) 

and the NFA's Interpretive Notice related to Compliance Rule 2-10. Bunched Orders may be entered using 

a designation for a group of accounts or suspense account number; provided, however that:

(1) the Bid/Offer or Pre-Arranged Cross is being placed by a Participant who is, or is 

acting on behalf of, an account manager for multiple accounts eligible for post execution allocation; 

or

(2) a written, pre-determined allocation scheme that defines the group of accounts has 

been provided to the Clearing Firm accepting or clearing the Bid/Offer prior to the time that such 

Bid/Offer is entered.

Rule 315 NEX SEF Authority over Transactions

(a) NEX SEF Authority Regarding Cancellations, Price Adjustments and Errors

NEX SEF has authority to cancel any transaction, to adjust the price of any transaction executed on the 

Facility, or to execute or require the execution of a new or offsetting transaction: (i) when NEX SEF 

determines in its sole discretion such action is necessary to mitigate system defects or market disrupting 

events, Disorderly Trading Conditions and breaches of capacity limits caused by the improper or erroneous 

use of a Trading Platform; (ii) at any time NEX SEF determines, in its sole discretion, that allowing a 

transaction to stand as executed may have a material adverse effect on the integrity of the market; or (iii) in 

accordance with Rule 315(c), (d), (h) or (i). All decisions of NEX SEF regarding NEX SEF's cancellation of 

transactions or the adjustment of transaction prices and the execution of new or offsetting transactions shall 

be final, subject to 315(d).

(b) Determination to Review a Transaction's Price

(1) NEX SEF may determine to review a transaction's price based on its independent 

analysis of market activity or upon a Participant's request. A Participant's request for review must 

be made (i) for an uncleared Pre-Arranged Cross, within one Business Day of the execution of such 

transaction, and (ii) for any other transaction executed on the Facility within 15 minutes of the 

execution of such transaction. In the absence of a timely request for review, NEX SEF may 

determine whether or not a transaction will be subject to review in its sole discretion. 

Notwithstanding the foregoing, subject to Applicable Law, NEX SEF shall amend the terms of, or 

cancel, any transaction that the parties, together with the DCO, as applicable, mutually agree to 

amend or cancel, in the event that such amendment or cancellation is not submitted to NEX SEF 

within the applicable review period specified above.
47

(2) If NEX SEF determines to review a transaction's price, it will promptly issue an 

alert to all Participants via a Trading Platform or electronic mail indicating that the transaction is 

under review.

(c) Review of a Transaction's Price

(1) In reviewing a transaction's price, NEX SEF shall determine the fair value price for 

the Swap at the time the transaction under review occurred. NEX SEF may consider any relevant 

information, including, but not limited to, the last transaction price of the Swap or a better Bid/Offer, 

a more recent price for a different maturity date, the price of the same or related Swap established 

in another venue or another market, the market conditions at the time of the transaction.

(2) If NEX SEF determines that the price of a transaction is a fair value price, NEX 

SEF will issue an alert indicating that the transaction shall stand as executed.

(3) If NEX SEF determines that the price of a transaction is not a fair value price, NEX 

SEF shall have the right, in its sole discretion, to cancel or adjust the price of such transaction. 

(d) Alternative Resolution by Agreement of Parties for Transactions Reviewed for Price

(1) With the approval of NEX SEF, parties to a transaction that is under review for 

price or that has had its price adjusted may instead, together with the DCO, as applicable, mutually 

agree to cancel or otherwise adjust the price of the transaction.

(2) With the approval of NEX SEF, parties to a transaction that is cancelled may 

instead, together with the DCO, as applicable, mutually agree to adjust the price of such transaction 

to a fair value price.

(3) Subject to sections (d)(i) and (d)(ii), parties to a transaction that is cancelled or that 

has had its price adjusted may mutually agree to a cash adjustment.

(4) Any cancellation or adjustment made pursuant to sections (d)(i), (d)(ii) or (d)(iii)

must be reported to the Facility by the parties within one (1) Business Day and the parties must 

maintain a record of such adjustment.

(e) Liability for Losses Resulting from Cancellations or Price Adjustments

(1) A party that through error or mistake enters a Bid/Offer or Pre-Arranged Cross that 

results in a cancellation or price adjustment shall be responsible for demonstrated claims of realised 

losses incurred by persons whose transaction prices were cancelled or adjusted; provided, 

however, that a claimant shall not be entitled to compensation for losses incurred as a result of the 

claimant's failure to take reasonable actions to mitigate the loss.

(2) A claim for a loss pursuant to this Rule 315 must be submitted to the Facility within 

one (1) Business Day of the event giving rise to the claim. NEX SEF will reject any claim that is 

not filed in a timely manner and such decision shall be final. Eligible claims shall be forwarded by 

NEX SEF to the party responsible for the Bid/Offer or Pre-Arranged Cross that resulted in a 

cancellation or a price adjustment of a transaction and the Participant through which the transaction 

was submitted to the Facility. Such party, or Participant on behalf of such party, shall, within ten 

(10) Business Days of receipt of the claim, admit or deny responsibility in whole or in part. Failure 

to respond to the claim within ten (10) Business Days shall be deemed a denial of liability.

(3) To the extent that liability is admitted, payment shall be made within ten 

(10) Business Days. Unless otherwise agreed upon in writing by the parties, failure to make the 

payment within ten (10) Business Days shall be deemed a denial of liability for the purposes of this 

Rule 315. A copy of any such written agreement must be provided to NEX SEF.
48

(4) To the extent that liability is denied, the party making the claim may submit the

claim for arbitration pursuant to Rule 702. Such claims must be submitted to NEX SEF within ten 

(10) Business Days of the date the party was issued notification that liability was denied.

(f) [Reserved]

(g) Reporting and Recording of Cancellations and Price Adjustments

(1) Cancelled transactions and any prices that have been adjusted shall be cancelled 

in NEX SEF's official records. 

(2) Transactions that have had their price adjusted shall be reflected in NEX SEF's 

official records at the adjusted price.

(h) Review of Transactions for Errors

(1) If a Participant, Customer or Clearing Firm believes that any transaction in one or 

more Contracts was executed, cleared or rejected from clearing as a result of an Error, as defined 

in Rule 315(h)(3), such person may request review of the transaction.

(2) Upon receipt of a request for review of a transaction, or if NEX SEF determines on 

its own initiative to conduct such a review, NEX SEF will review its records to determine if an Error 

occurred.

(3) NEX SEF may cancel or adjust the transaction, or execute or require the execution 

of a new or offsetting Cleared Contract under the procedures of Rule 315(i), as appropriate, if the 

review described in this Rule reveals that:

(i) a Trading Platform made a material mistake or that a mistake occurred as 

a result of a malfunction in a Trading Platform or by human error; or

(ii) a Bid/Offer or Pre-Arranged Cross was incorrectly displayed and/or 

executed and/or reported; or

(iii) a Trading Platform, Participant or Customer made a clerical or operating 

error or omission that caused a transaction to be rejected from clearing 

and void ab initio; or

(iv) a Clearing Firm or DCO rejected a leg of a Package Transaction for 

clearing because of the sequencing of submission for clearing of the legs 

of the applicable Package Transaction (each of the foregoing, an "Error").

(4) If the review described in this Rule reveals that no Error occurred, NEX SEF will 

inform any person who requested the review that NEX SEF has determined that the transaction 

was properly handled, the evidence supporting that determination, and that a cancelation, 

adjustment or a new or offsetting transaction under Rule 315(i) will not be made.

(5) NEX SEF will document in writing all requests for review of transactions received 

by NEX SEF, or any review on its own initiative, the time and manner in which NEX SEF reviewed 

its electronic audit trail in response to the request or review on its own initiative, the outcome of that 

review, and the action or actions taken by NEX SEF in response to that review.

(6) If a transaction is reviewable for price under Rule 315(b), the procedures of this 

Rule 315(h) shall not apply. 
49

(i) Procedures for Correcting Errors

(1) The procedures of this Rule 315(i) are in accordance with NAL 17-27, expiring on 

the effective date of revised Commission regulations governing swaps with clerical and operational 

errors executed on a swap execution facility, and are limited to:

(i) A Cleared Contract that was rejected for clearing and void ab initio

because of a clerical or operational error or omission by NEX SEF, a 

Participant or a Customer (each, a "Rejected Transaction"),

(ii) A leg of a Package Transaction that was rejected for clearing because of 

the sequencing of submission for clearing of the legs of the applicable 

Package Transaction and only for such rejected leg (each, a "Rejected 

Leg"), and

(iii) A Cleared Contract that is carried on a DCO's books as a result of a clerical 

or operational error or omission by NEX SEF, a Participant or a Customer 

that was not identified until after the Cleared Contract had been cleared 

(each, an "Erroneously Cleared Transaction"),

in each case where the Facility has affirmatively determined that the transaction or a term 

thereof resulted from an Error.

(2) For Rejected Transactions and Rejected Legs, if a Participant, Customer or 

Clearing Firm believes that a transaction qualifies as a Rejected Transaction or a Rejected Leg, 

such Participant, Customer or Clearing Firm shall request review of the transaction pursuant to 

Rule 315(h).

(i) Upon completion of the review of the transaction pursuant to Rule 315(h), 

if NEX SEF determines that an Error resulted in a Rejected Transaction or 

a Rejected Leg and:

A. If NEX SEF is able to determine how to correct the Error, NEX 

SEF shall execute a new Cleared Contract with the same terms 

as the Rejected Transaction or Rejected Leg, other than the Error, 

without obtaining consent of the Participant that submitted the 

Rejected Transaction or Rejected Leg or the Customer on whose 

behalf such transaction was submitted. The new Cleared 

Contract must be submitted by a NEX SEF customer service 

representative as a Pre-Arranged Cross, and such Pre-Arranged 

Cross shall be subject to pre-execution credit check and risk 

screening pursuant to Rule 204(b).

B. If NEX SEF is unable to determine how to correct the Error, NEX 

SEF shall consult with the Clearing Firms for the Rejected 

Transaction or Rejected Leg and the Participants and Customers 

involved in such transaction, as necessary, and the Clearing Firms 

for such transactions may, with the consent of each respective 

Customer or Participant, agree to a new Cleared Contract with the 

same terms as the Erroneously Cleared Contract, other than the 

Error. Such Customer or Participant consent may not be obtained 

in advance, and must be sought and obtained by each Clearing 

Firm on a case-by-case basis, after the Cleared Contract has 

been rejected. If there is such agreement and consent, the new 

Cleared Contract must be submitted by the Participant specified 

in Rule 304(b) as a Pre-Arranged Cross pursuant to the procedure 

in Rule 304(b), and such Pre-Arranged Cross shall be subject to 
50

pre-execution credit check and risk screening pursuant to Rule 

204(b).

(ii) Upon execution of such Pre-Arranged Cross by NEX SEF to replace a 

Rejected Transaction or Rejected Leg, NEX SEF shall submit the 

transaction to the DCO for clearing as quickly as technologically 

practicable, but in any case no later than 60 minutes from the issuance of 

the notice of rejection by the DCO to the Clearing Firms.

(iii) If the new Cleared Contract resulting from such Pre-Arranged Cross is 

rejected from clearing, it is void ab initio and no additional new Cleared 

Contract will be permitted to be submitted under the procedure in this Rule 

315(i)(2).

(iv) NEX SEF shall report Swap transaction data to the relevant SDR pursuant 

to Rule 309(f) for a new Cleared Contract that clears with the same terms 

as the Rejected Transaction or Rejected Leg, as applicable, other than the 

Error, including: a Part 43 cancellation for the original transaction, a 

Part 45 termination indicating the original transaction is void ab initio, and 

swap transaction data pursuant to Parts 43 and 45 for the new Cleared 

Contract. Such data shall reference the original cancelled trade, indicate 

that it has been reported pursuant to the procedures described in this Rule 

315(i)(2) and link the original cancelled trade to the new trade for reporting 

to the relevant SDR under Part 43 and Part 45 of the Commission 

Regulations.

(v) The procedures in this Rule 315(i)(2) are not available for Rejected Legs 

of Package Transactions that are rejected for clearing by a Clearing Firm 

or DCO because the Package Transaction as a whole failed to satisfy the 

applicable Risk-Based Limits.

(3) For Erroneously Cleared Transactions, if a Participant, Customer or Clearing Firm 

believes that a Cleared Contract is carried on the books of a DCO as a result of an Error, such 

Participant, Customer or Clearing Firm may request review of the transaction pursuant to Rule 

315(h).

(i) Upon completion of the review of the transaction pursuant to Rule 315(h), 

if NEX SEF determines that an Error resulted in an Erroneously Cleared 

Transaction and:

A. If NEX SEF is able to determine how to correct the Error, NEX 

SEF shall execute a Cleared Contract that offsets the Erroneously 

Cleared Transaction carried on the books of the relevant DCO 

through the same Clearing Firms that cleared the Erroneously 

Cleared Transaction and NEX SEF shall execute a new Cleared 

Contract with the same terms as the Erroneously Cleared 

Transaction, other than the Error, in each case without obtaining 

consent of the Participant that submitted the Erroneously Cleared 

Transaction or the Customer on whose behalf such transaction 

was submitted; provided that, where an Erroneously Cleared 

Transaction did not satisfy the Risk-Based Limits of a Participant's 

Clearing Firm, NEX SEF shall obtain the consent of the relevant 

Clearing Firm prior to executing such offsetting Cleared Contract. 

The new Cleared Contract must be submitted by a NEX SEF 

customer service representative as a Pre-Arranged Cross, and 
51

such Pre-Arranged Cross shall be subject to pre-execution credit 

check and risk screening pursuant to Rule 204(b).

B. If NEX SEF is unable to determine how to correct the Error, NEX 

SEF shall consult with the Clearing Firms for Erroneously Cleared 

Transactions and the Participants and Customers involved in such 

transaction, as necessary, and the relevant Customer or 

Participant may agree to execute a Cleared Contract that offsets 

the Erroneously Cleared Transaction carried on the books of the 

relevant DCO through the same Clearing Firms that cleared the 

Erroneously Cleared Transaction and to execute to a new Cleared 

Contract with the same terms as the rejected Cleared Contract, 

other than the Error. The new Cleared Contracts must be 

submitted by the Participant specified in Rule 304(b) as 

Pre-Arranged Crosses pursuant to the procedure in Rule 304(b), 

and such Pre-Arranged Crosses shall be subject to pre-execution 

credit check and risk screening pursuant to Rule 204(b).

(ii) Upon execution of such Pre-Arranged Crosses by NEX SEF to offset an 

Erroneously Cleared Transaction and to enter into a new Cleared 

Contract, NEX SEF shall submit the transactions to the DCO for clearing 

as quickly as technologically practicable, but in any case no later than 

three days after the Erroneously Cleared Transaction was executed.

(4) For the avoidance of doubt, the procedures of this Rule 315(i) are not applicable 

to any transaction rejected by a DCO for credit reasons.

(j) Prime Broker Transactions

(1) A Prime Broker shall have the right to have the Facility cancel any Prime Broker 

Transaction within 48 hours after the execution of such transaction if such transaction was executed 

in excess of a Prime Broker Limit established by the Prime Broker with respect to the Prime Broker 

Transaction.

(2) The Prime Broker shall communicate the cancellation request directly to the 

Facility and the counterparty and indicate which Prime Broker Limit was exceeded with respect to

the Prime Broker Transaction. 

(3) In the event a Prime Broker Transaction is canceled by the Facility pursuant to this 

Rule 315(j), the Facility will report such cancellation to the relevant SDR pursuant to Part 43 of the 

Commission Regulations. 

(4) In the event the counterparty to the canceled Prime Broker Transaction disputes 

the right of the Prime Broker to have the Facility cancel such transaction, the dispute will be 

resolved in accordance with the procedures of Chapter 7.

Rule 316 Reporting Counterparty

(a) For each Contract executed on or subject to the Rules, NEX SEF shall report all required 

data to an SDR in accordance with Rule 309(g), and shall include in such creation data the identification of 

the reporting counterparty. The reporting counterparty will be determined by NEX SEF, if possible, in 

accordance with Commission Regulation 45.8 (a) – (f) and in the event the counterparties to the Contract 

are of the same hierarchy level, the ISDA Reporting Party Rules, the relevant portion of which is attached 

to this Rulebook as Annex 1, and identify to the counterparties which is the reporting counterparty. If NEX 

SEF is unable to determine the reporting counterparty in accordance with Commission Regulation 45.8(a) 

– (f) and the ISDA Reporting Party Rules, NEX SEF will identify the buyer of the Contract as the reporting 

counterparty in the creation data. By executing the Contract on the Facility, the counterparties agree to the 
52

use of the ISDA Reporting Party Rules and where necessary, the identification of the buyer as reporting 

counterparty, and waive the opportunity to agree separately upon a reporting counterparty and to receive 

notice from NEX SEF, as provided in Commission Regulation 45.8(d) and 45.8(f).

(b) For each Contract executed on or subject to the Rules, the reporting counterparty and/or 

the relevant DCO is responsible for reporting continuation data to the SDR to which the creation data for 

the Contract was first reported in accordance with Commission Regulations 45.4 and 45.10.

Rule 317 Direct Electronic Access 

No Participant may provide Direct Electronic Access to the Facility to its underlying clients.

made not untrue or misleading, in connection with or related to any transaction on or other activity related 

to NEX SEF or the Facility.

CHAPTER 5

RULE ENFORCEMENT

Rule 501 Jurisdiction

(a) NEX SEF shall have the authority to initiate and conduct investigations, and prosecute 

Violations committed by Facility Subject Persons, and to impose sanctions for such Violations as provided 

in these Rules.

(b) Each Participant and Clearing Firm, upon becoming a Participant and Clearing Firm and 

thereafter upon any change of address shall file with NEX SEF a written notice designating an address for 

receiving service of documents. If a Participant or Clearing Firm fails to designate such an address, service 

by mail to its address on file with NEX SEF shall be good service, and delivery thereof shall be deemed to 

have occurred as of the date of such mailing.

Rule 502 Facility Market Regulation Staff Powers and Duties

(a) It shall be the duty of the Compliance Function to enforce these Rules, and shall have the 

authority to inspect the books and records of all Facility Subject Persons and the authority to require any 

Facility Subject Person to appear before it to answer questions regarding matters being investigated by the 

Market Regulation Staff. The Compliance Function may also delegate such authority to Market Regulation 

Staff who shall consist of personnel of NEX SEF, and such other Regulatory Services Providers as NEX 

SEF may hire on a contract basis. The Compliance Function shall ensure that surveillance systems are 

established to monitor trading to prevent manipulation, price distortion and any other form of market abuse, 

identify system disruptions in relation to the Contracts and Disorderly Trading Conditions and otherwise 

ensure compliance with these Rules. Such monitoring may be done by the Market Regulation Staff or a 

third party provider, and shall include real-time monitoring and the ability to conduct comprehensive and 

accurate transaction reconstructions.

(b) The Market Regulation Staff shall conduct investigations of possible Violations, prepare 

written reports respecting such investigations, furnish such reports to the Review Panel and conduct the 

prosecution of such Violations. An investigation must be commenced upon receipt of a request from any 

Regulatory Agency, its staff or receipt of information (such as data produced by automated surveillance 

systems) by NEX SEF that in the judgment of the Market Regulation Staff indicates a reasonable basis for 

finding that a Violation may have occurred or will occur. Absent mitigating factors, each investigation will 

be completed no later than 12 months after the investigation is opened. Mitigating factors include the 

complexity of the investigation, the number of firms or individuals involved as potential wrongdoers, the 

number of potential Violations to be investigated and the volume of documents and data to be examined 

and analysed by Market Regulation Staff.

(c) If, in any case, the Compliance Function or another member of the Market Regulation Staff, 

designated for this purpose by the Compliance Function, concludes that there is a reasonable basis for 

finding a Violation, he or she shall (i) present an investigation report concerning the matter to the Review 

Panel or (ii), in the case of Violations subject to summary suspension under Rule 514or summary fines 

under Rule 516 proceed in accordance with Rule 514 or Rule 516, as applicable. The investigation report 

must include the reason the investigation was initiated; a summary of the complaint, if any; the relevant 

facts; Market Regulation Staff's analysis and conclusions; and a recommendation as to whether disciplinary 

action should be pursued. The report may also include the Facility Subject Person's disciplinary history at 

the Facility, including copies of any warning letters. The Market Regulation Staff may issue a warning letter, 

including for minor transgressions. However, no more than one warning letter may be issued to the same 

person found to have committed the same Violation more than once in a rolling 12-month period.

(d) If, in any case, the Compliance Function or another member of the Market Regulation Staff, 

designated for this purpose by the Compliance Function, concludes that no reasonable basis exists for 

finding a Violation, he or she must prepare a written investigation report including the reason the 
57

investigation was initiated; a summary of the complaint, if any; the relevant facts; and Market Regulation 

Staff's analysis and conclusions. The Compliance Function or another member of the Market Regulation

Staff may issue a warning letter in any case where it is concluded that no reasonable basis exists for finding 

a Violation, without limitation on the number of warning letters issued to a person.

(e) Before presenting an investigation report to the Review Panel, the Market Regulation Staff 

may, in its sole discretion, inform the prospective Respondent that it intends to submit the matter to the 

Review Panel, and at such time the proposed Respondent may submit an offer of settlement to the Hearing 

Panel, in accordance with the procedures of Rule 509, prior to presentation of the investigation report to 

the Review Panel.

(f) NEX SEF has contracted with NFA to act as Regulatory Services Provider to provide 

certain regulatory services to NEX SEF, including reviews of the Facility's audit trail information for potential 

Violations. NEX SEF will retain ultimate decision-making authority with respect to any regulatory services 

to be provided by NFA.

(g) NEX SEF or its Regulatory Services Provider shall have the right with such prior 

reasonable advance notice as is practicable under the circumstances (unless in furtherance of regulatory 

purposes in which case without prior notice to Facility Subject Persons), in connection with determining 

whether all Rules are being, will be, or have been complied with by the Facility Subject Person, to: 

(i) inspect systems, equipment and software of any kind operated by the Facility Subject Person in 

connection with accessing, and the Facility Subject Person's transacting on, the Facility, wherever located; 

(ii) access, either physically or electronically, the systems, equipment, software, and the premises on which 

the systems, equipment, and software are located, any data stored in any of the systems or equipment, 

during the regular business hours; and/or (iii) copy or reproduce any data to which NEX SEF has access 

under this Rule. Each Facility Subject Person shall provide the Regulatory Services Provider with the same 

access to its books and records and offices as it is required to provide to NEX SEF under the Rules and 

Applicable Law.

Rule 503 The Review Panel

(a) The Review Panel shall have the power to direct that an investigation of any suspected 

Violation be conducted by the Market Regulation Staff, and shall hear any matter referred to it by the Market 

Regulation Staff regarding a suspected Violation.

(b) The Review Panel shall be appointed by the Board, and shall be comprised of five persons, 

including at least two Participants and at least two non-Participants. In the case where the subject of the 

investigation is a Clearing Firm, at least one member of the Review Panel shall be a Clearing Firm. The 

Board shall appoint as chairman (the "Review Panel Chairman") of the Review Panel a person who would 

not be disqualified from serving as a "Public Director" as defined in Commission Regulations. Three panel 

members shall constitute a quorum for any action, so long as they are in attendance at the time of the 

relevant action. The Review Panel may not include any members of the Market Regulation Staff, any 

person involved in adjudicating any other stage of the same Proceeding, or any person with a history of 

disciplinary offenses that would be disqualifying under CFTC Regulation § 1.63(c). The Review Panel shall 

include at least one member that is not a member of NEX SEF whenever the Review Panel is: (i) acting 

with respect to a disciplinary action in which the Respondent is a member of the Board, the Review Panel 

or the Hearing Panel; or (ii) when the suspected Violation involves manipulation (or attempted manipulation) 

of the price of a Contract or conduct which directly results in financial harm to a non-member of NEX SEF. 
58

The Review Panel shall include sufficient different membership interests so as to ensure fairness and to 

prevent special treatment or preference for any person.

(c) All information, records, and documents provided to the Review Panel, and all related 

records and documents shall be treated as confidential and shall not be disclosed, except as necessary to 

further a NEX SEF investigation or as required by Applicable Law.

(d) Upon receipt of an investigation report, the Review Panel shall promptly review the report 

and, within thirty (30) days of receipt, take one of the following actions:

(1) if the Review Panel determines that additional investigation or evidence is needed, 

it shall promptly direct the Market Regulation Staff to conduct further investigation;

(2) if the Review Panel determines that no reasonable basis exists for finding a 

Violation or that prosecution is otherwise unwarranted, it may direct that no further action be taken. 

Such determination must be in writing and must include a written statement setting forth the facts 

and analysis supporting the decision; or

(3) if the Review Panel determines that a reasonable basis exists for finding a Violation 

and adjudication is warranted, it must direct that the Facility Subject Person alleged to have 

committed the Violation be served with a notice of charges as set forth in Rule 504.

(e) If the Review Panel determines that there may have been a Violation but that no 

adjudication is warranted, the Review Panel may issue a warning letter to the Facility Subject Person 

informing it that there may have been a Violation and that such continued activity may result in disciplinary 

sanctions. Where a Violation is determined to have occurred, no more than one warning letter for the same 

potential Violation may be issued to the same person during a rolling 12 month period.

Rule 504 Notice of Charges

(a) If the Review Panel determines that a reasonable basis exists for finding a Violation and 

adjudication is warranted, the Compliance Function shall serve a notice of charges (a "Notice") on the 

Facility Subject Person alleged to have been responsible for the Violation (such Facility Subject Person, 

the "Respondent"). Such Notice shall state:

(1) the acts, practices or conduct with which the Respondent is charged;

(2) the Rules allegedly violated and how such acts, practices or conduct constitute a 

Violation of such Rules;

(3) that the Respondent is entitled, upon written request filed with NEX SEF, within 

thirty (30) days of service of the Notice, to a formal hearing on the charges;

(4) that the failure of the Respondent to request a hearing within thirty (30) days of 

service of the Notice, except for good cause shown, shall be deemed a waiver of its right to a 

hearing;

(5) that the failure of the Respondent to file an Answer (as defined in Rule 505) with 

the Market Regulation Staff within thirty (30) days of service of the Notice shall be deemed an 

admission of all of the acts, practices or conduct alleged in the Notice; and

(6) that the failure of the Respondent to expressly deny a particular charge contained 

in the Notice shall be deemed an admission of such acts, practices or conduct.

(7) A Respondent shall have the right to be represented by legal counsel or any other 

representative of its choosing in all succeeding stages of the disciplinary process, except by any 
59

member of the Board, Review Panel or Hearing Panel, any employee of NEX SEF or any person 

substantially related to the underlying investigation, such as a material witness or Respondent.

Rule 505 Answer; Request for Hearing; Failure to Answer or Deny Charges

(a) The Respondent shall serve on the Compliance Function a written answer (an "Answer") 

to the Notice and a written request for a hearing on the charges within thirty (30) days of the date of service 

of the Notice. The Answer must include a statement that the Respondent admits, denies, or does not have 

and is unable to obtain sufficient information to deny each allegation. A statement of lack of sufficient 

information shall have the effect of a denial of the allegation.

(b) The Respondent's failure to file an Answer within such thirty (30) day period shall be 

deemed an admission of all allegations contained in the Notice.

(c) The Respondent's failure to expressly deny a particular charge contained in the Notice 

shall be deemed an admission of such acts, practices or conduct.

(d) The Respondent's failure to request a hearing within such thirty (30) day period, absent 

good cause shown, shall be deemed a waiver of Respondent's right to a hearing.

Rule 506 Selection of Hearing Panel

(a) Formal hearings on any Notice shall be conducted by the Hearing Panel selected by the 

Board. The Hearing Panel shall include at least two Participants and at least two non-Participants. In the 

case where the subject of the investigation is a Clearing Firm, at least one member of the Hearing Panel 

shall be a Clearing Firm. The Board shall also select, as chairman of the Hearing Panel ("Hearing Panel 

Chairman"), a person who would not be disqualified from serving as a "Public Director" as defined in 

Commission Regulations. The Hearing Panel Chairman, in his or her sole discretion, shall set a date for 

the hearing (the "Hearing Date"). The Hearing Panel may not include any members of the Market 

Regulation Staff, any person involved in adjudicating any other stage of the same Proceeding, or any 

person with a history of disciplinary offenses that would be disqualifying under CFTC Regulation § 1.63(c). 

The Hearing Panel shall include at least one member that is not a member of NEX SEF whenever the 

Hearing Panel is: (i) acting with respect to a disciplinary action in which the Respondent is a member of 

the Board, the Review Panel or the Hearing Panel; or (ii) when the suspected violation involves 

manipulation (or attempted manipulation) of the price of a Contract or conduct which directly results in 

financial harm to a non-member of NEX SEF. The Hearing Panel shall include sufficient different 

membership interests so as to ensure fairness and to prevent special treatment or preference for any 

person.

(b) The Hearing Panel Chairman shall notify the Market Regulation Staff and the Respondent 

of the Hearing Date and the names of the members of the Hearing Panel at least fifteen (15) days prior to 

the Hearing Date.

(c) No member of the Hearing Panel shall hear a case in which that member has a direct 

financial, personal or other interest in the matter under consideration.

Rule 507 Challenge to Members of the Hearing Panel

Within ten (10) days after service on the Respondent of notice of the Hearing Date and names of the 

members of the Hearing Panel, the Respondent may challenge, in writing, the inclusion of any member of 

the Hearing Panel for cause, including without limitation, if the member has a direct financial, personal or 

other interest in the matter under consideration. The merits of such challenge shall be finally decided by 

the Regulatory Oversight Committee. If said written challenge is not received within such ten (10) day 

period, absent good cause shown, any such right to challenge is deemed waived.
60

Rule 508 Hearing on Sanctions in the Event of Failure to Deny Charges; Failure to Request 

Hearing Deemed Acceptance of Sanctions

In the event the Respondent fails to file an Answer or admits or fails to deny the charge of a Violation 

contained in the Notice, the Hearing Panel shall find the Respondent guilty of each such Violation and may 

impose a sanction for each such Violation subject to the limitations set forth in Rule 511(b)(7). The Hearing 

Panel shall promptly notify the Respondent of any such sanction and of the Respondent's right to a hearing 

on the sanction within the period of time which shall be stated in the notice, after the imposition of such 

sanction. Failure to request a hearing on the sanction in a timely manner, absent good cause shown, shall

be deemed to be acceptance of the sanction.

Rule 509 Settlement Prior to Commencement of Hearing

(a) Prior to the commencement of the hearing, the Hearing Panel may accept a written offer 

of settlement from the Respondent, whereby the Respondent, without either admitting or denying any 

Violations, may agree to:

(1) a cease and desist order;

(2) a fine for each Violation plus the monetary value of any benefit received as a result 

of the Violation (provided that in no case shall any fine exceed $100,000 per Violation); 

(3) restitution of any counterparty harm; and/or

(4) revocation or suspension of Trading Privileges or Customer or Clearing Firm status

of the Respondent.

(b) If the Hearing Panel accepts an offer of settlement, it must issue a written decision 

specifying each Violation it has reason to believe was committed, including the basis for the Hearing Panel's 

conclusions. The sanctions must include full counterparty restitution where counterparty harm is 

demonstrated, except where the amount of restitution or to whom it should be provided cannot be 

reasonably determined. If an offer of settlement is accepted without the support of the Market Regulation 

Staff, the decision must adequately support the Hearing Panel's acceptance of the settlement. Where 

applicable, the decision must include a statement that the Respondent has accepted the sanctions imposed 

without either admitting or denying any Violations. Any sanctions imposed pursuant to an offer of settlement 

must take into account the Respondent's disciplinary history.

(c) The Respondent may withdraw an offer of settlement at any time before final acceptance 

by the Hearing Panel. If an offer is withdrawn after submission, or is rejected by the Hearing Panel, the 

Respondent may not be deemed to have made any admissions by reason of the offer of settlement and 

may not be otherwise prejudiced by having submitted the offer of settlement.

Rule 510 Hearing Procedures

(a) In every instance where a Respondent has requested a hearing on a charge that is denied, 

or on a sanction set by the Hearing Panel pursuant to Rule 508, the Respondent will have the opportunity 

for a hearing in accordance with the procedures of this Rule.

(b) The Hearing Panel shall determine the procedures to be followed in any hearing before it, 

except that the following shall apply in every case:

(1) The hearing must be fair and must be promptly convened after reasonable notice 

to the Respondent.

(2) The prosecution shall be conducted by the Market Regulation Staff.
61

(3) The Respondent shall be allowed to appear personally at the hearing, and to be 

represented by legal counsel or any other representative of its choosing and, either personally or 

through such representative, to present witnesses and documentary evidence and to crossexamine witnesses.

(4) The Market Regulation Staff and the Respondent shall deliver to each other a 

statement listing the witnesses expected to be called and the documents expected to be introduced 

into evidence, together with copies of such documents, by ten (10) days' prior notice to the hearing 

or as the Hearing Panel may reasonably specify. Unless the Hearing Panel, in its discretion, waives 

compliance with this requirement, no witness may testify and no documentary evidence may be 

introduced into evidence unless listed in and, in the case of documents, furnished with such 

statement. On written request, the Market Regulation Staff shall provide the Respondent with 

access to all books, documents or other tangible evidence in the possession or under the control 

of NEX SEF which are to be relied upon by the Market Regulation Staff or which are relevant to the 

charges; provided, however, that protected attorney work product, attorney-client communications 

and investigative work product, including the investigation report, are neither discoverable by a 

Respondent nor subject to review by a Respondent as part of the investigation file.

(5) NEX SEF shall require that persons within its jurisdiction who are called as 

witnesses participate in the hearing and produce evidence, and will make reasonable efforts to 

secure the presence of all other persons called as witnesses whose testimony would be relevant. 

Failure by a Facility Subject Person to so participate and produce evidence when requested by 

NEX SEF shall be a Violation.

(6) No formal rules of evidence shall apply, and the Hearing Panel shall be free to 

accept or reject any and all evidence it considers proper, but the hearing may not be so informal 

as to deny a fair hearing.

(7) Neither the Market Regulation Staff, the Respondent, any witnesses testifying 

before the Hearing Panel nor any other person within the Facility's jurisdiction shall engage in 

conduct that may impede the progress of a hearing or the fair and just resolution of the subject 

matter thereof, and any such conduct may itself constitute a Violation.

(8) Ex parte contacts by any of the parties with members of the Hearing Panel shall 

not be permitted.

(9) A substantially verbatim record capable of being accurately transcribed shall be 

made of the Proceeding, provided, however, that such record need not be transcribed, unless the 

transcript is requested by the Respondent or an applicable regulator, or unless the decision is 

appealed to the Commission or reviewed by the Commission on its own motion. In all other 

instances, a summary record of the hearing is permitted.

(10) The cost of transcribing the record of the hearing must be borne by a Respondent 

who requests the transcript, or whose application for Commission review of the disciplinary action 

has been granted. In all other instances, the cost of transcribing the record will be borne by NEX 

SEF.

(11) The Notice, the Answer, any stenographic transcript of the hearing, the 

documentary evidence and any other material presented to the Hearing Panel by either party with 

notice to the other shall constitute the record of the hearing (the "Hearing Record").

(12) The burden of proof shall be on the prosecution to prove a Violation by a 

preponderance of the evidence. A finding of a Violation shall be made by majority vote based on 

the Hearing Panel's decision as to the weight of the evidence contained in the Hearing Record.

(13) All sanctions imposed by the Hearing Panel must be commensurate with the 

Violations committed and must be clearly sufficient to deter additional similar Violations by the 
62

Respondent and similar Violations by other Facility Subject Persons. All sanctions must take into 

account the Respondent's disciplinary history. In the event of demonstrated counterparty harm, 

any sanctions must include full counterparty restitution, except where the amount of restitution or 

to whom it should be provided cannot be reasonably determined.

Rule 511 Written Decision of Hearing Panel

(a) Promptly following a hearing conducted in accordance with Chapter 5 of the Rules, the 

Hearing Panel shall render a written decision based upon the weight of evidence in the Hearing Record 

and must provide a copy to the Respondent within thirty (30) days of such decision. 

(b) The written decision shall include:

(1) the name of the Respondent;

(2) the Notice or a summary of the charges alleged in the Notice;

(3) the Answer, if any, or a summary of the Answer;

(4) a summary of the evidence produced at the hearing or, where appropriate, 

incorporation by reference of the investigation report;

(5) a statement of the findings and conclusions of the Hearing Panel with respect to 

each charge, and a complete explanation of the evidentiary and other basis for such findings and 

conclusions with respect to each charge, or in the event of a settlement, a statement specifying the 

alleged Violations;

(6) an indication of the Contract involved, if any, and each specific Rule that the 

Respondent was found to have violated and whether the Violation resulted in any financial harm to 

any Participants or Customers; 

(7) an order stating any sanctions imposed, including the basis for the sanctions, any 

terms of the sanctions, the date the determination to impose sanctions was made and the effective 

date of such sanctions; the sanctions that may be imposed on the Respondent shall be one or more 

of the following:

(i) a cease and desist order;

(ii) a fine for each Violation plus the monetary value of any benefit received

as a result of the Violation (provided that in no case shall any fine exceed 

$100,000 per Violation);

(iii) restitution of counterparty harm, except where the amount of restitution or 

to whom it should be provided cannot be reasonably determined; and/or 

(iv) the issuance of a suspension or revocation of Trading Privileges or 

Customer or Clearing Firm status of the Respondent; and

(8) a statement informing the respondent that the imposition of sanctions may be 

appealed to the Commission pursuant to Part 9 of the Commission Regulations.

(c) The Hearing Panel shall take into consideration the Respondent's disciplinary history prior 

to imposing any disciplinary sanctions.

(d) NEX SEF shall also provide the written decision to the NFA through BASIC. 
63

(e) If NEX SEF suspends or revokes the Trading Privileges or Customer or Clearing Firm 

status of the Respondent, or otherwise disciplines the Respondent, it must publicly publish and maintain 

on its website the information contained in the written notice pursuant to Rule 511(b).

Rule 512 Liability for Expenses

Any Respondent that, after notice and opportunity for hearing, has been found to have committed a 

Violation may, in the discretion of the Hearing Panel appointed in the matter, be required to pay to NEX 

SEF an amount equal to any and all reasonable and documented out-of-pocket expenses incurred by NEX 

SEF in connection with the prosecution of such Violations, in addition to any fine or other monetary sanction 

which may be imposed upon such Respondent by virtue of the Violations found by the Hearing Panel.

Rule 513 Effective Date of Sanctions

(a) If a Respondent submits an offer of a settlement to the Hearing Panel, any sanction 

included as a part of such settlement shall become final and effective on the date that the Hearing Panel 

approves such settlement, or on such other date as is specified in the decision.

(b) Subject to Rule 513(c) and (d), any decision (including any sanctions) by a Hearing Panel 

pursuant to this Chapter 5 or the Participation Committee (or Board acting in such capacity) pursuant to (a)

shall be the final decision of NEX SEF and shall become effective fifteen (15) days, or such longer time as 

the Hearing Panel or Participation Committee (or Board acting in such capacity) may specify, after a copy 

of the written decision of the Hearing Panel or Participation Committee (or Board acting in such capacity)

has been served on the Respondent, applicant, Participant or Customer as applicable. 

(c) In any case where a Respondent, applicant, Participant or Customer has consented to the 

action taken and to the timing of its effectiveness, the Hearing Panel or Participation Committee (or Board 

acting in such capacity) may cause the decision involving any disciplinary action (including any sanctions) 

to become effective prior to the fifteen (15) day period.

(d) Any decision (including any sanctions) by a Hearing Panel or the Participation Committee 

(or Board acting in such capacity) may become effective prior to the time set forth in Rule 513(b) if:

(1) NEX SEF reasonably believes, and so states in its written decision, that immediate 

action is necessary pursuant to Rule 514(a); 

(2) NEX SEF determines and so states in its written decision, that the actions of a 

Facility Subject Person have impeded the progress of a disciplinary hearing; or

(3) NEX SEF determines a Facility Subject Person has violated Rules relating to timely 

submission of accurate records required for clearing or verifying each day's transactions or other 

similar activities.

(e) If a decision is to become effective earlier than the time set forth in Rule 513(b) pursuant 

to Rule 513(c) or (d), NEX SEF shall notify the Respondent, applicant, Participant or Customer in writing 

stating the reasons for the determination and shall notify the Commission in accordance with the

Products — Rule 801:

(1) Non Deliverable Forwards ("NDFs")

Product Specifications

NDFs are synthetic foreign currency forward contracts on non-convertible currencies or are traded on 

currencies with very little liquidity in the market place. These derivatives allow corporates and other 

investors to hedge or take positions to local currency movements without actually dealing in the underlying.

A (notional) principle amount, forward exchange rate and forward date are all agreed at the deal's inception. 

The difference is that there will be no physical transfer of the principle amount in the transaction. The deal 

is agreed on the basis that net settlement will be made in USD, or another fully convertible currency, to 

reflect any differential between the agreed forward rate and the actual exchange rate on the agreed forward 

date. It is a cash-settled outright forward.

The demand for NDFs arises principally out of regulatory and liquidity issues in the underlying currency, 

where overseas players are essentially barred from access to the domestic market.

When an NDF deal is contracted, a fixing methodology is agreed, which includes the following two

methodologies:

1. Outright. Under the standard outright NDF contract a fixing spot rate is determined on the fixing 

date, which is normally two working days before settlement, to reflect the spot value. 

2. Tomorrow's Fixing ("TOM"). The TOM methodology permits a currency position to be rolled 

forward one month on the day before the fixing used to price the contract. The contract is a backto-back trade with a near leg closing out the original currency position (the "Original NDF") and a 

far leg reestablishing the position the next trading day. The fixing rate applicable to the far leg is 

the current market rate for the relevant outright NDF contract at the time the contract is entered 

into. The fixing rate for the near leg is the far leg fixing rate minus a number of basis points

agreed upon by the parties (the "Near Leg Rate"). The close out of the Original NDF is then 

calculated as the difference between the fixing rate applicable to the Original NDF and the Near 

Leg Rate. 

In all cases, the fixing spot rate is based on the reference page on either Reuters or Bloomberg. Settlement 

is made in the major currency, paid to or by the client, and reflects the differential between the agreed upon 

non-deliverable forward rate and the fixing spot rate.
69

The NDF is quoted using foreign exchange forward market convention, with two way prices quoted as 

bid/offer pips, at a premium or discount to the prevailing spot market. As with a normal forward transaction, 

the market user either buys or sells the NDF, depending on the position to be hedged or according to the 

view of the underlying currency of interest rates.

NDFs are a risk management tool used to hedge the risk of forward currency convertibility, which can result 

from a number of factors, including credit risk, sovereign risk, regulatory restrictions, or lack of settlement 

procedures. NDFs are typically utilized by banks, multinational corporations, investment managers, and 

proprietary traders to hedge currency risk. NDFs are also used as a tool to facilitate locking in the enhance 

yields of emerging market currencies.

Rule 802(4) — Non Deliverable Swaps

An ND IRS trade has many trade terms. For example, notional amount, fixed interest rate, floating rate, 

reference rate, holiday convention, etc. The deal is agreed on the basis that net settlement will be made in 

USD, or another fully convertible currency, to reflect any differential between the agreed fixed rate and the 

actual floating rate on the settlement dates. ND IRS are quoted as Offer/Bid. For ND IRS the fixed leg is 

quoted, hence it is Fixed Income Swap.

ND IRS

o An agreement between two parties (known as counterparties) where one stream of future 

interest payments is exchanged for another based on a specified principal amount. Interest 

rate swaps often exchange a fixed payment for a floating payment that is linked to an interest 

rate (most often the LIBOR). The interest rate cash flows are net settled in a major currency 

on fixing date. A company will typically use interest rate swaps to limit or manage exposure 

to fluctuations in interest rates, or to obtain a marginally lower interest rate than it would have 

been able to get without the swap.

o Interest rate swaps are simply the exchange of one set of cash flows (based on interest rate 

specifications) for another. Because they trade OTC, they are really just contracts set up 

between two or more parties, and thus can be customized in any number of ways.

which generally means two business days from the trade date (T+2). It is possible to settle trades 

on dates other than the spot date, in which case the rate will be adjusted by forward points to 

compensate for the interest rate differential between the two currencies being traded. The “Value 

Date Calendar” is the calendar available within the NEX SEF Dealing Service that displays Value 

Date information by currency pair and month.

(d) DEALING ON NEX SEF DEALING SERVICE

The NEX SEF Dealing Service is designed to facilitate the matching of Bids/Offers. This 

creates a Transaction that can result in a Deal or multiple Deals.

(1) Transactions. Each Deal consists of a Maker and Taker. Deals may consist of 

two unique Counterparties or may comprise different Trader ID’s of the same Counterparty when 

intrafloor dealing is enabled. Intrafloor dealing is enabled as a default on the NEX SEF Dealing 

Service. A match between the same Trader IDs is not permitted.

(2) Bids/Offers

(i) Bids/Offers are a means for an Authorized Trader to express a limit price 

(or better) at which he or she is willing to transact. Bids/Offers are limit orders that reside in the Order Book. 

Bids/Offers that do not immediately result in a match are considered passive and enter the Order Book. 

Bids/Offers that are fully executed upon submission as a result of an Automatch are not displayed on the 

Order Book. The resulting execution is reflected in Market View Information if the Deal constitutes a new 

high or low price within the Price Distribution Interval.

(ii) There are three matching engines in the NEX SEF Dealing Service: in 

London, New York and Tokyo. Once a Bid/Offer enters the Order Book at the local matching engine, except 

for those Bids/Offers that result in an Automatch, the NEX SEF Dealing Service distributes that Bid/Offer 

or the remaining unmatched balance of the Bid/Offer to the other two matching engines. 

(iii) Bids/Offers can match:

A. Immediately:

1. with other Bids/Offers as an Automatch Taker, or

2. with a Pip/Price Discretion Bid/Offer as a Maker; or

B. subsequently:

1. with other aggressive Bids/Offers as a Maker,

2. with Hits as a Maker,

3. with a Pip/Price Discretion Bid/Offer as a Maker, or

4. with a Pip/Price Discretion Bid/Offer as a Taker.

(iv) Bids/Offers that do not result in a match will remain active in the Order 

Book until:

A. interrupted in accordance with Protocol Rule (d)(4)(i);

B. interrupted due to loss of connectivity, or an EBS Ai or Workstation 

Heartbeat disconnect;

C. interrupted due to the end of the weekly trading session;

D. interrupted due to the end of the trading session for instruments 

that have a designated open/close;

E. an auto interrupt is triggered;

F. a successive Bid/Offer replaces a prior Bid/Offer;
97

G. removed by the Facility in accordance with Protocol Rule (i); 

H. cancelled or amended in accordance with Facility Rule 310; or

I. matched in full.

(v) Hits on the NEX SEF Dealing Service can be Buys or Sells. A “Buy/Sell” 

means a Bid/Offer entered into the EBS Dealing Service which is IOC, as defined below.

(vi) Hits can be defined as “IOC” (Immediate or Cancel) for Bids/Offers that do 

not reside in the Order Book. 

(vii) A Hit will be matched if the Facility Order Book contains an active Bid/Offer 

at an equal or better price at time of the match. 

(viii) A Hit will match immediately or will be canceled if the target liquidity is 

missed or no longer available. 

(ix) If Work the Balance is set to "partial", then a Bid/Offer for the unmatched 

balance will be initiated only when some portion of the Hit has been satisfied.

(x) If Work the Balance is set to always, then a Bid/Offer for the unmatched 

balance will be initiated regardless of whether the hit was partially filled or totally missed.

(xi) Hits can match immediately:

A. with passive Bids/Offers as a Taker, or

B. with a Pip/Price Discretion Bid/Offer as a Taker.

(xii) The unmatched balance of Hits which have enabled Work the Balance will 

match as a Bid/Offer in accordance with Protocol Rule (d)(3).

(3) Matching Priority

(i) Once a Bid/Offer is submitted, including a Held Order, the NEX SEF 

Dealing Service will immediately attempt to match the request with a 

Bid/Offer of better or equal price. Each match attempt is prioritized in 

shown price, time priority. The matching engine to which a Bid/Offer is 

submitted (New York, London or Tokyo) is defined as the local one; the 

others being remote. Local Bids/Offers that do not match immediately are 

inserted into the Order Book ahead of remote Bids/Offers at the same 

price. 

(ii) When a match or multiple matches are initiated, the NEX SEF Dealing 

Service initiates processing to complete each Deal. This Deal processing, 

which is unique to the NEX SEF Dealing Service’s distributed matching 

logic, includes the following validations:

A. Verification at the Maker matching engine that the Maker Bid/Offer 

is still available; and

B. Verification that sufficient credit exists between the two 

Counterparties.

(iii) If a match does not result in a Deal, the NEX SEF Dealing Service will 

reactivate the Bid/Offer into the NEX SEF Dealing Service according to 

the rules of price, time priority. 
98

(4) Interrupt Rules

(i) A request by a Counterparty to interrupt a Bid/Offer can be submitted at 

any time during the lifetime of the Bid/Offer. Upon receipt of the interrupt 

at the matching engine, no additional matches will be initiated against the 

outstanding balance of the Bid/Offer. Matches which have been initiated 

by the matching engine prior to the receipt of the interrupt message cannot 

be interrupted. 

(ii) The Facility may cancel a Bid/Offer as provided in the Facility Rulebook. 

(e) THE MATCHING PROCESS

(1) Each Trading Privilege Holder or Authorized Trading Firm must establish a 

relationship with its Counterparties, satisfy itself of the creditworthiness of its Counterparties and 

extend credit to them as it sees fit. For a match to be made in the NEX SEF Dealing Service, 

mutual credit must exist between the two Counterparties. If credit has not been established with 

or given by another Counterparty, or when credit given by or to a Counterparty is exhausted, the 

prices submitted by a Counterparty will not be considered a Dealable Bid/Offer for the other. 

(2) Once hits and Bids/Offers have been matched, any successful Deal will depend 

on the available Credit Limits remaining for each Trading Floor. If there is insufficient mutual credit 

to complete the Deal for the full size of the Deal, the size of the Deal will be reduced to the amount 

of mutual credit available. In order for a Deal to complete the size of the Deal must not be greater 

than the amount of available credit given by the Counterparty who has the lower amount of credit 

available for the other. 

(3) Once a Deal takes place, credit is reduced for each Counterparty with the other for 

the size of the Deal. If there is no successful Deal, then the credit of the two Counterparties is 

unaffected.

(4) Advanced Order Types

(i) “Pip Discretion”: For each Bid/Offer an Authorized Trader may define a 

dealable range up to/down from the shown limit price that is displayed in 

the Order Book. The full Bid/Offer amount is visible in the Order Book at 

the limit price but the Pip Discretion range defined by the Authorized 

Trader is not visible.

(ii) “Price Discretion”: Price Discretion offers the ability via EBS Ai for an 

Authorized Trader to attach a hidden aggress price range to an active 

Bid/Offer. There is an EBS defined maximum discretionary price range per 

currency pair which is contained in the EBS Guide to Currency Pair 

Parameters.

(iii) “Iceberg Orders” consist of a shown amount and hidden amount, for 

which the minimum required and maximum permitted values differ by 

currency pair. These may be found in the EBS Guide to Currency Pair 

Parameters. Iceberg Bids/Offers are available on the EBS Workstation, 

EBS Global Access and via EBS Ai. The matching of Iceberg Bids/Offers 

is based on shown price, time priority, and size and/or time randomization 

algorithms may be applied to each order. The following items set forth a 

description of certain aspects of Iceberg Bids/Offers:

A. Size randomization is an NEX SEF Dealing Service algorithm that 

minimizes the market impact of an Iceberg Order. The shown 

amount will be replenished for a random size ranging from the 
99

minimum required shown amount for the pair, up to the original 

shown amount of the Bid/Offer.

B. Time randomization is an NEX SEF Dealing Service algorithm that 

minimizes the visibility of Bid/Offer replenishment, with a 

configurable upper limit value from 1 second to 9 seconds. 

Following the full satisfaction of the shown amount of an Iceberg 

Order, replenishment will occur after a randomized time interval 

expires (100 millisecond increments.) 

C. It is important to note that the hidden amount of an Iceberg Order 

is in the Order Book and available for matching at all times and 

the market cannot trade through the Bid/Offer level until the total 

Bid/Offer amount is fully satisfied. 

D. If no other inventory is available at the price level, the time 

randomization algorithm is superseded and replenishment will 

occur immediately.

E. Randomization algorithms may be turned on or off by Bid/Offer.

(5) Deal Status

When a Maker’s Bid/Offer matches with a Taker’s Bid/Offer on the 

NEX SEF Dealing Service, execution is deemed to occur once a 

match verification message is received by the Taker. If for any 

reason the NEX SEF Dealing Service fails to process all Deal 

messages or fails to process all Deal messages in a timely fashion 

as defined by the NEX SEF Dealing Service, that Deal shall be 

designated as being in an unverified state. In such cases the 

Facility will contact all Counterparties to the trade and notify them 

of the status of the trade as “Done” or “Not Done”.

(f) POST TRADE

(1) Deal Tickets

(i) After each Transaction a Deal Ticket is produced by the NEX SEF Dealing 

Service and sent to the Trading Privilege Holder or Authorized Trading 

Firm. 

A. The Facility may provide an automated feed, the “EBS Deal Feed 

Client”, notifying a Trading Privilege Holder or Authorized Trading 

Firm of the Deals to which the Trading Privilege Holder or 

Authorized Trading Firm is a party, if the Trading Privilege Holder 

or Authorized Trading Firm chooses. It is the Trading Privilege 

Holder’s or Authorized Trading Firm’s responsibility to ensure that 

the Trading Privilege Holder’s or Authorized Trading Firm’s 

software is able to receive the EBS Deal Feed Client and that the 

interface is properly installed, tested and working. The EBS Deal 

Feed Client is not available to Trading Privilege Holders or 

Authorized Trading Firms who connect solely through the Global 

Access interface. 
100

(2) Confirmations

(i) In accordance with Facility Rule 312, each Deal executed on the NEX SEF 

Dealing Service shall be deemed to incorporate the following wording 

which, together with the information contained within the EBS Deal Feed 

Client (to the extent that a Trading Privilege Holder or Authorized Trading 

Firm has elected to receive the EBS Deal Feed), will be deemed to be the 

Confirmation of such Deal:

ANY PREEXISTING AGREEMENTS BETWEEN THE COUNTERPARTIES THAT 

ARE NOT INCONSISTENT WITH THIS CONFIRMATION, THE INFORMATION 

CONTAINED IN THE EBS DEAL FEED CLIENT OR THE NEX SEF RULEBOOK, 

ARE HEREBY DEEMED INCORPORATED BY REFERENCE.

THE TRANSACTION SHALL BE GOVERNED BY NEW YORK LAW, EXCEPT 

THAT GOVERNING LAW FOR PREEXISTING AGREEMENTS BETWEEN THE 

COUNTERPARTIES IS AS MAY BE OTHERWISE AGREED BETWEEN THE 

PARTIES.

COUNTERPARTIES MUST INFORM THE FACILITY IMMEDIATELY OF ANY 

QUERY OR DISCREPANCY ON THE EBS CLIENT DEAL FEED. ANY REQUEST 

FOR REVIEW MUST BE MADE TO THE FACILITY WITHIN 15 MINUTES OF THE 

FACILITY’S EXECUTION OF THE TRANSACTION. 

NEX SEF AND ITS AFFILIATES PROVIDING SERVICES TO THE FACILITY 

ACCEPT NO LIABILITY FOR THE COMMERCIAL ADVISABILITY OF THIS 

TRANSACTION. THIS CONFIRMATION SUPERSEDES ANY PREVIOUS 

AGREEMENTS BETWEEN THE COUNTERPARTIES REGARDING THE TERMS 

OF THE TRANSACTION OTHER THAN AS MAY BE INCORPORATED HEREIN. 

IF A CONFIRMATION RELATING TO THE TRANSACTION SPECIFIED HEREIN 

IS DELIVERED TO YOU BOTH VIA A THIRD PARTY OR THIRD-PARTY 

SERVICE (SUCH AS MARKITWIRE, RTNS, ECONFIRM OR CONFIRMHUB) 

(EACH, A “THIRD-PARTY CONFIRMATION”) OR DIRECTLY AS A BILATERAL 

CONFIRMATION FROM YOUR COUNTERPARTY, AS WELL AS SEPARATELY 

FROM NEX SEF (WHETHER DIRECTLY OR VIA ANY TRADING PRIVILEGE 

HOLDER OR AUTHORIZED TRADING FIRM), THEN THE INFORMATION IN 

THE EBS DEAL FEED CLIENT TOGETHER WITH THE WORDING IN THIS 

PROTOCOL RULE (f)(2)(i) SHALL BE DEEMED TO BE THE LEGALLY BINDING 

CONFIRMATION OF NEX SEF RELATING TO SUCH TRANSACTION, AND NOT 

THE THIRD-PARTY CONFIRMATION. TRANSACTIONS EXECUTED AS 

CLEARED TRANSACTIONS ARE VOID AB INITIO AND WILL BE CANCELED 

BY NEX SEF IF NOT ACCEPTED FOR CLEARING IN ACCORDANCE WITH THE 

FACILITY RULEBOOK.

NEX SEF IS NOT A PRINCIPAL TO THE TRANSACTION AND IS NEITHER 

LIABLE NOR RESPONSIBLE FOR THE DUE PERFORMANCE OF ANY OF THE 

TERMS SET OUT ABOVE. IN THE EVENT OF A DISPUTE, THE 

COUNTERPARTIES SHALL HOLD NEX SEF AND ITS AFFILIATES PROVIDING 

SERVICES TO THE FACILITY HARMLESS FROM ANY LIABILITY ARISING OUT 

OF THEIR OPERATION OF THE FACILITY AND/OR PROVISION OF SERVICES 

TO THE FACILITY.

(3) Settlement

(i) The Trading Privilege Holder or Authorized Trading Firm is entirely 

responsible for all aspects of Transaction settlement, including but not 

limited to: all payments; any procedures supplemented to (but consistent 
101

with) the provisions of this System Protocol and any liability for default by 

such Trading Privilege Holder or Authorized Trading Firm.

(ii) 17:00 EST is the point at which the trade date moves to the next day. 

However, when a trade is done on a Saturday before 17:00 EST the 

effective trade date is Friday, and when the trade is done after 17:00 EST 

on a Saturday the effective trade date is the following Monday. There are 

exceptions to this general Protocol Rule, and the information regarding 

these exceptions is contained in the EBS Guide to Currency Pair 

Parameters.

(iii) The Facility uses recognized industry sources to update the Value Date 

Calendar on the Workstation and Global Access. In the event of a Value 

Date dispute, Trading Privilege Holders and Authorized Trading Firms 

shall make their own bilateral determination of the applicable Value Date 

in accordance with standard market convention. 

(g) TRADING FLOOR ADMINISTRATOR

(1) TFA General

(i) Each Trading Privilege Holder and Authorized Trading Firm must appoint 

at least one TFA for each Trading Floor. At least one TFA must be 

available to communicate with and be accessible to the Facility and 

Trading Privilege Holders or Authorized Trading Firms at all times while 

the NEX SEF Dealing Service is in use at the Trading Floor. A TFA or other 

Authorized Trader must also be present when maintenance of the NEX 

SEF Dealing Service is taking place at the Trading Floor.

(ii) The TFA is responsible for the supervision of operations of the NEX SEF 

Dealing Service on the Trading Privilege Holder’s or Authorized Trading 

Firm’s Trading Floor with a view to ensuring the smooth running of the 

NEX SEF Dealing Service. Any issues arising in relation to the NEX SEF 

Dealing Service shall be handled in accordance with the Facility Rulebook 

and relevant User Guides. These operational responsibilities include 

trading activities and system support of all hardware used at the Trading 

Floor for dealing on the NEX SEF Dealing Service. 

(iii) In the case of the NEX SEF Prime Service there will be a master 

agreement between the Prime Broker and the relevant NEX SEF Prime 

Service Trading Privilege Holder (the “Prime Master Agreement”). The 

Trading Privilege Holder must ensure that responsible persons are 

identified in respect of the minimum requirements with which it must 

comply under the Prime Master Agreement. 

(2) Security

(i) Each TFA has his or her own ID and password which allow access to 

specific TFA functions. The Facility provides the TFA with his or her initial 

password and the first time the TFA signs on he or she will be required to 

change his or her password; this does not apply in respect of Global 

Access. 

(ii) It is the responsibility of each Trading Privilege Holder and Authorized 

Trading Firm to determine and implement adequate security systems and 

procedures at its Trading Floor(s). With respect to Global Access, it is the 

responsibility of each Trading Privilege Holder and Authorized Trading 
102

Firm to follow the security requirements and procedures prescribed by the 

Facility in the EBS Global Access User Guide.

(iii) In respect of Global Access, it is the responsibility of the TFA to notify the 

Facility immediately where access to the NEX SEF Dealing Service of an 

Authorized Trader has been terminated or otherwise invalidated. 

(3) Credit and Settlement 

(i) It is the responsibility of the TFA to maintain Credit Limits with each 

Counterparty with whom the Trading Privilege Holder or Authorized 

Trading Firm wishes to deal. It is also the responsibility of the TFA to enter 

settlement instructions in respect of each currency pair the Trading 

Privilege Holder or Authorized Trading Firm wishes to transact. 

(ii) In the case of the NEX SEF Prime Service the TFA must also maintain 

Credit Limits between the Prime Broker and the relevant NEX SEF Prime 

Service Trading Privilege Holder in accordance with Facility Rule 215. An 

Authorized Trader on a Trading Floor can deal with a Counterparty if there 

is sufficient mutual credit to deal in the Minimum Deal Size in any Product. 

The “Minimum Deal Size” is defined by the NEX SEF Dealing Service for 

each Product. The “Minimum Credit Threshold” is the minimum amount 

of credit necessary for a successful Deal of the Minimum Deal Size for the 

instrument with the highest value on the NEX SEF Dealing Service. 

(iii) Where new Trading Privilege Holders or Authorized Trading Firms are 

granted access to the NEX SEF Dealing Service, it is the responsibility of 

the TFA to review the status of these prospective Counterparties for credit 

purposes and for the Trading Privilege Holder or Authorized Trading Firm 

to consider allocating Credit Limits to each such Counterparty or group of 

Counterparties. It is also the responsibility of the TFA to review from time 

to time the credit status of existing Counterparties.

(iv) The NEX SEF Dealing Service provides warning messages indicating 

when the credit used for a Counterparty or group of Counterparties has 

reached a certain percentage of the Credit Limit for that Counterparty. 

This percentage is set by the TFA. The NEX SEF Dealing Service will 

provide a message when the Credit Limit allocated to a Counterparty or 

group of Counterparties has been exhausted or is insufficient to allow a 

Deal to take place for the Minimum Deal Size.

(4) Risk Management

(i) In addition to the ability to manage risk through the operation of prescreened credit, a Trading Privilege Holder or Authorized Trading Firm 

trading NDFs will be able to manage risk in two further ways:

A. “Volatility Factor”: the TFA may assign a percentage for every 

NDF currency pair or tenor. The NEX SEF Dealing Service default 

will be 100%.

B. “Scaling Factor”: a TFA may assign a scaling factor (a rational 

number greater than zero), for each currency pair or tenor. 

Alternatively a TFA may choose to utilize the square root of time 

to maturity (in days) for all currency pairs or tenor. The default 

Scaling Factor will be set to 1.0.
103

(5) User Maintenance and Access

(i) The TFA is responsible for allocating an initial ID to each Authorized 

Trader. The NEX SEF Dealing Service will allocate the Trading Floor 

default password to the Authorized Trader. When an Authorized Trader 

first signs on using this default password, he/she is required to change the 

password immediately. For Global Access, in addition to the above, the 

Facility will complete the user authentication process on behalf of the TFA. 

(ii) An Authorized Trader shall comply with the following password 

procedures:

A. change passwords regularly;

B. never use another Authorized Trader’s ID to sign on;

C. never disclose passwords to other Authorized Traders or any 

other person;

D. always sign off at the end of a trading session;

E. never automate the sign on process (unless as part of the EBS Ai 

Client Application); and

F. never turn off the monitor while signed on.

(iii) It is the responsibility of an Authorized Trader to contact the TFA if 

problems arise in the sign on process or if a password is forgotten. If an 

Authorized Trader believes that someone else has obtained his or her 

password, he or she must change his password and notify the TFA.

(iv) An Authorized Trader must only be signed on using his or her own ID and 

password at one Workstation at any one time.

(v) An Authorized Trader is given three opportunities to enter a correct 

password prior to having his or her Trader ID disabled. In the event that 

an Authorized Trader’s ID is disabled, the Authorized Trader must contact 

his or her TFA who will reset his or her Trader ID. If the TFA is not 

available, the Authorized Trader may contact the Facility for assistance.

(vi) After the sign on procedure has been successfully completed, the 

Authorized Trader will receive the date and time of his or her last sign on. 

At this time the Authorized Trader may receive a “message of the day”. 

The Authorized Trader is responsible for contacting the TFA if the date 

and time displayed does not correspond to when he or she last signed on.

(vii) At the discretion of the Facility, any Workstation may be signed off by the 

Facility. In these instances, any outstanding Bids/Offers will be removed 

by the NEX SEF Dealing Service automatically.

(h) TRADING PRIVILEGE HOLDER OR AUTHORIZED TRADING FIRM SUPPORT

Facility Customer Support is available 24x7 to assist Trading Privilege Holders or 

Authorized Trading Firms with all issues pertaining to the NEX SEF Dealing Service.
104

(1) Counterparty Support Obligations

If a Trading Privilege Holder or Authorized Trading Firm suspects a problem with 

the NEX SEF Dealing Service which it considers may affect its use of the NEX 

SEF Dealing Service, an Authorized Trader must immediately:

(i) remove all of that Trading Privilege Holder’s or Authorized Trading Firm’s 

Bids/Offers from the NEX SEF Dealing Service and

(ii) contact Facility Customer Support.

Facility Customer Support may require, at its sole discretion that:

(i) all Bids/Offers submitted by that Trading Floor be removed; 

(ii) all Authorized Traders of that Trading Floor stop using the NEX SEF 

Dealing Service; and/or

(iii) the Trading Privilege Holder or Authorized Trading Firm provide 

information in connection with the issue to Facility Customer Support.

(2) Matching/Deal Disputes

(i) Deal Queries

A. In the event of a query as to the terms of a Deal, the Trading 

Privilege Holder or Authorized Trading Firm may contact Facility 

Customer Support which will, where possible, provide the Trading 

Privilege Holder or Authorized Trading Firm with contact details 

for the Counterparty to facilitate direct resolution between the two 

Counterparties. Except as otherwise provided for in the Facility 

Rulebook, Facility Customer Support will not amend the Deal 

status or rate details, which remains the preserve of the two 

Counterparties concerned.

(ii) NEX SEF Prime Service and EBS Ai Deal Queries

A. A Counterparty’s deal code may appear to EBS counterparties as 

a result of Deals originating from any or all of the following:

1. Workstation dealer;

2. Global Access;

3. EBS Ai; or

4. NEX SEF Prime Service Trading Privilege Holders and 

Authorized Trading Firms, in which case the deal code of 

the Prime Broker is supplied.

B. All Prime Brokers and other Counterparties using EBS Ai must 

ensure that all potential Counterparties know how to contact a 

representative of the relevant Trading Privilege Holder or 

Authorized Trading Firm (such as via conversational direct dealing 

or telephone). In the event of a disputed Deal, each Trading 

Privilege Holder or Authorized Trading Firm must ensure that its 

representative is authorized to make immediate decisions to 

resolve such trade disputes on behalf of the Trading Privilege 
105

Holder or Authorized Trading Firm, including, if appropriate (within 

the context of the ACI Model Code and other applicable dealing 

conventions), the execution of an offsetting Deal. 

C. In order to facilitate timely resolution of Deal queries, each Trading 

Privilege Holder or Authorized Trading Firm must:

1. establish an Authorized Trader naming convention which 

guarantees uniqueness across all of its Authorized 

Traders associated with the same four-letter EBS deal 

code ascribed to such Trading Privilege Holder or 

Authorized Trading Firm;

2. communicate this Authorized Trader ID naming 

convention to its Authorized Traders, and ensure that 

such Authorized Traders are aware of its internal 

escalation procedures so that queries related to this Deal 

code can be forwarded to the appropriate contacts at all 

times of the trading day; and

3. provide Facility Customer Support with primary and 

secondary 24/7 contact details for each of its relevant 

business areas using the NEX SEF Dealing Service. The 

designated contacts must be authorized to make 

immediate decisions to resolve any Deal disputes on 

behalf of the organization. The Facility must also be 

authorized to disclose such contact details to 

Counterparties on request in order to facilitate resolution 

of issues. 

(i) ADDITIONAL RULES FOR AI TRADING

(1) EBS Ai is an alternative means of accessing the NEX SEF Dealing Service. “EBS 

Ai” is defined as a message-based interface that supports a two-way message exchange between 

the NEX SEF Dealing Service and the Trading Privilege Holder’s or Authorized Trading Firm’s 

trading application. 

(2) Trading Privilege Holders or Authorized Trading Firms shall only use EBS Ai, EBS 

Ai Application and Market View Information to implement their high frequency/program trading 

models. 

(3) Bid/Offer Throughput and Outstanding Active Bids/Offers

(i) The EBS Ai Server limits the number of Bids/Offers that can be submitted 

within a rolling time window (throughput limit) defined by the NEX SEF 

Dealing Service and the maximum number of Bids/Offers which can 

remain outstanding in the Facility market at a given time. Once the 

throughput limit is reached for a given time window, additional Bids/Offers 

are rejected until at least one Bid/Offer is executed or canceled, or until 

the time window has passed. Limits are subject to change and may vary 

depending on the instruments traded through the NEX SEF Dealing 

Service and will be communicated to all Trading Privilege Holders or 

Authorized Trading Firms prior to the commencement of trading (5:00 a.m. 

Sydney local time).
106

(4) Maintenance of Orderly Markets

(i) In order to maintain an orderly market, the Facility may enforce each of 

the following protocols on selected NEX SEF NDF currency pairs upon a 

determination by the Market Regulation Staff, in its sole discretion, that 

one or more Participants may be engaging in trading in such currency 

pairs in violation of Chapter 4:

A. Quote Fill Ratio (“QFR”). The QFR is a minimum percent of 

passive Bid/Offer submissions. 

B. Hit Fill Ratio (“HFR”). The HFR is a minimum percent of 

aggressive Bid/Offer submissions.

C. Minimum Quote Life (“MQL”). The MQL represents the amount of 

time a Participant’s Bids/Offers must rest in the Order Book before 

they can be interrupted by the Participant.

D. Distributed Quote Interrupt (“DQI”). The DQI holds all Bid/Offer 

interrupt messages during periods in which the Market Regulation 

Staff determines there is a pattern of disruptive Bids/Offers 

originating from one or more regions during non-core trading 

hours for such regions. 

(ii) Any QFR and/or HFR: 

A. shall, for all Bids/Offers other than those covered by paragraph 

(B) below, be calculated by the Market Regulation Staff based on 

historical analysis of fill patterns on completed Deals - measured 

daily, weekly (5-day rolling average) and monthly; 

B. shall be based on the total notional value of Deals divided by the 

number of Bids/Offers submitted by a Participant or Trading Floor, 

as applicable;

C. may vary by timezone and/or time of day; 

D. may be calculated and applied either to each Participant or to 

each Trading Floor of each Participant, as the Market Regulation 

Staff may determine in its discretion; and 

E. may be subject to such thresholds, including minimum number of 

Bids/Offers submitted by a Participant or Trading Floor, as 

applicable, as the Market Regulation Staff may determine to 

apply. 

(iii) If the Market Regulation Staff determines to enforce a QFR and/or HFR, 

prior notice will be provided to all Participants in an MRAN indicating (i) 

the affected NEX SEF NDF currency pair(s); (ii) the relevant QFR and/or 

HFR percentage; (iii) the calculation methodology used to establish such 

percentage; (iii) any relevant thresholds applicable to the relevant QFR 

and/or HFR percentage and whether such thresholds would be 

aggregated across IDs and deal codes or on a per-Trading Floor basis; 

(iv) whether the QFR and/or HFR will be applied at the Participant level or 

at the Trading Floor level; and (v) the time and date the QFR and/or HFR 

will be put into effect. The QFR and/or HFR will apply to all Bids/Offers 
107

submitted to the Order Book (regardless of Participant access method) by 

each Participant for the relevant NEX SEF NDF currency pair. 

(iv) If a Participant fails to meet the applicable QFR and/or HFR then in effect, 

the Market Regulation Staff may deem such failure a Violation of Rule 406 

and may take any of the following actions in its sole discretion at any time:

A. impose on that particular Participant a MQL on selected NEX SEF 

NDF currency pairs. If enforced, MQL will apply to all Bids/Offers 

submitted to the Order Book by the affected Participants for the 

relevant NEX SEF NDF currency pair; 

B. impose on that particular Participant, for Bids/Offers submitted via 

EBS Ai (other than end-of-month products), a requirement to 

maintain a minimum top of book MQL of 90% > 1s;

C. prohibit the Participant from quoting or streaming passive 

Bids/Offers and the Participant will accordingly be limited to 

submitting aggressive Bids/Offers; 

D. summarily suspend the Participant in accordance with Facility 

Rule 514; and

E. submit such deemed Violation of Rule 406 to the Review Panel in 

accordance with the formal disciplinary procedures of Chapter 5. 

(v) If a Participant continues to fail to meet the QFR and/or HFR after the 

Facility has taken any of the foregoing actions, the Facility may suspend 

the Participant from EBS or the Facility in its entirety in accordance with 

Facility Rule 206 following completion of the disciplinary procedures set 

forth in Chapter 5. 

(vi) Sample MQL, QFR and HFR ranges for NEX SEF NDF pairs are included, 

for reference, in the attached Product Appendix.

(vii) The Market Regulation Staff may impose a DQI on all Participants, which 

will hold all Bid/Offer interrupt messages until one or more of the regions 

in non-core trading hours confirm that there is no Deal pending for the 

relevant Bid/Offer. If the Market Regulation Staff determines to enforce a 

DQI, a new QFR may be imposed upon any Participant that have been 

identified as submitting the disruptive Bids/Offers during the relevant 

period. The Facility shall provide notice to any affected Participant, which 

shall include: (i) the affected NEX SEF NDF currency pair(s); 

(ii) information with respect to the QFR imposed, including whether the 

QFR will be applied at the Participant level, deal code level or at the 

Trading Floor level; and (iii) the time and date the QFR will be put into 

effect.

(viii) The Facility may exempt a Participant, who is part of a Market Maker 

program, from the MQL, QFR, HFR and/or DQI parameters. Such 

exemption would only be for currency pairs covered by the Market Maker 

program, might not include all currency pairs in the market maker program, 

and would apply equally to all Participants that are part of such Market 

Maker program.
108

(ix) Self Match / Painting the Tape.

A. Self matching, if considered disruptive by the Market Regulation 

Staff, is also prohibited and may be systemically prevented.

B. “Painting the tape”, whereby apparently unrelated parties collude 

to buy and sell a particular currency pair among themselves to 

create artificial trading activity at one or more price levels, is 

prohibited trading activity.

(5) Validations

Price validation is an EBS Ai configurable item and will depend upon the values of 

the EBS Ai parameters such as PriceCheck, WideDifferenceCheck and 

LargeDifferenceCheck. Bids/Offers are screened to ensure that they are not 

inverted or quoted outside of the acceptable range for the Product. Bids/Offers 

with off-market prices are rejected by the EBS Ai server. “Off-market” transactions 

are defined according to parameters which are set out in the EBS Ai Developer’s 

Guide, which is a User Guide available to Trading Privilege Holders or Authorized 

Trading Firms upon request. 

(i) Maximum Trade Size

There is a limit on the size of a single Bid/Offer that can be accepted at 

the EBS Ai server. Bids/Offers exceeding that limit are rejected by the 

EBS Ai server. The limit is set out in the EBS Ai Developers Guide. The 

Facility will notify Trading Privilege Holders or Authorized Trading Firms 

who are using the EBS Ai product as and when limits are changed.

(6) Link Integrity/Certification

(i) The EBS Ai server requires that the EBS Ai Client Application follows the 

published protocol closely (as set out in the EBS Ai Developer’s Guide). 

Any protocol errors are interpreted as Trading Privilege Holder or 

Authorized Trading Firm system failures. Any failure of the EBS Ai Client 

Application (including a protocol error) will cause the EBS Ai server 

immediately to interrupt all active Bids/Offers and reset the connection with 

the EBS Ai Client Application in order to attempt to protect the Trading 

Privilege Holder or Authorized Trading Firm. A failure by the EBS Ai Client 

Application to maintain Heartbeats will also cause the EBS Ai server to 

immediately interrupt all active Bids/Offers and reset the connection with 

the EBS Ai Client Application.

THE FACILITY IS NOT RESPONSIBLE FOR AND ACCEPTS NO 

LIABILITY FOR ANY SUCH INTERRUPTION OR CONNECTION RESET.

(7) Market View Information

(i) EBS Ai provides a feed of market data known as “Market View 

Information”. The Market View Information is available as a creditscreened update and is published to each Trading Privilege Holder or 

Authorized Trading Firm EBS deal code at intervals determined by the 

Facility. Ai Market View Information in excess of 24 hours may not be 

stored by a Trading Privilege Holder or Authorized Trading Firm. 
109

(ii) In the case of the NEX SEF Prime Service where a NEX SEF Prime 

Service Trading Privilege Holder may be utilizing multiple Prime Brokers, 

only one Market View may be enabled.

ANNEX 1 Reporting Counterparty Rules

Relevant Portions of Reporting Counterparty Rules

(a) The ISDA Reporting Party Rules are set forth below by asset class: 

(1) Credit: 

(i) Where both parties are the same hierarchy level (e.g., Major Swap Participant vs. 

Major Swap Participant, Swap Dealer vs. Swap Dealer, or non‐Swap Dealer/Major 

Swap Participant vs. non‐Swap Dealer/Major Swap Participant), the reporting 

counterparty is the floating rate payer (a/k/a ‘seller’). For swaptions, the reporting 

counterparty is the floating rate payer of the underlying swap. 

(ii) For real time reporting of step‐in novations, the reporting counterparty should be 

determined between the transferor and transferee based on the above and the 

position of the transferee. So, if both parties are of the same classification and the 

transferee is the seller (floating rate payer) in the novated transaction, the 

transferee is the reporting counterparty. If the transferee is the buyer (fixed rate 

payer), then the transferor is the reporting counterparty.

(iii) For novated transactions, the reporting counterparty should be reassessed 

between the transferee and remaining party based on the above.

(2) Rates: 

(i) Product Attribute Determination: 

Reporting Counterparty Tiebreaker Logic - Rates

Trade Type Explanation Reporting Counterparty

Cap/ Floor When a single Fixed Rate Payer

exists

Fixed Rate Payer. Otherwise, Reverse ASCII sort, first LEI/Entity 

ID

Debt Option All Option Buyer

Exotic All Reverse ASCII sort, first LEI/Entity ID

FRA All Fixed Rate Payer

IRS Basis All Reverse ASCII sort, first LEI/Entity ID

IRS Fix-Fix All Reverse ASCII sort, first LEI/Entity ID

IRS Fix-Float All Fixed Rate Payer

IRSwap: Inflation When a single Fixed Rate Payer 

exists

Fixed Rate Payer. Otherwise, Reverse ASCII sort, first LEI/Entity 

ID

IRSwap: OIS All Fixed Rate Payer

Swaption All Option Buyer

XCCY Basis All Reverse ASCII sort, first LEI/Entity ID

XCCY Fix-Fix All Reverse ASCII sort, first LEI/Entity ID

XCCY Fix-Float All Fixed Rate Payer

(ii) Tiebreaker Logic. When the participant identifier tiebreaker is invoked the 

following processes will be used:

(A) Determining identifiers. When an entity has multiple entity identifiers 

(“IDs”), the following hierarchy will be used to determine which entity ID to 

use in the reporting counterparty determination logic: LEI/CiCi is used 

before DTCC GTR ID which is used before an AVOX ID which is used 

before any other identifier.
121

(B) Identifier Tiebreaker Logic Scenarios:

i. When both firms must have an LEI/CiCi then rank based on the 

two LEI/CiCis.

ii. When one firm has an LEI/CiCi and the other firm has a DTCC ID 

but does not have an LEI then rank based on the comparison of 

the LEI/CiCi to the DTCC ID.

iii. When one firm has an LEI/CiCi and the other firm has an AVOX 

ID but does not have an LEI then rank based on the comparison 

of the LEI/CiCi to the AVOX ID

iv. When neither firm has an LEI/CiCi and both firms have a DTCC 

ID then rank based on the two DTCC IDs.

v. When neither firm has an LEI/CiCi and one firm has a DTCC ID 

and the other firm has only an AVOX ID then rank based on the 

comparison of the DTCC ID to the AVOX ID.

vi. A firm will be the reporting counterparty when that firm has a 

DTCC ID or LEI/CiCi and the other has neither an LEI/CiCi nor a 

DTCC ID nor an AVOX ID. Please note that in all cases the 

reporting counterparty will have a DTCC ID and by extension will 

have an LEI/CiCi.

(iii) Determining sort of order of identifiers: 

i. LEI/CiCi, DTCC GTR IDs, and AVOX IDs are comprised of 

characters from the following set {0‐9, A‐Z}.

ii. For avoidance of doubt, before comparing IDs convert all IDs to 

UPPER CASE only.

iii. For comparison basis the sort order will be reverse ASCII sort 

order. For avoidance of doubt the following are sort order of 

precedence:

iv. Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, 

C, B, A, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0.

(iv) When comparing two IDs the reporting counterparty will be the firm with the first 

ID in the list when sorted in reverse ASCII sort order. 

(3) Equity: Where both parties are the same hierarchy level, the reporting counterparty will be 

the:

(i) Seller of performance on any product in the current version of the OTC Derivatives 

Products Taxonomies published by ISDA, which is attached as Attachment 2 to 

this Annex 1 (the “Taxonomy”). 

(ii) Seller of product on all other (exotic) products in the Taxonomy.

(iii) If seller cannot be identified the fall back would be for the parties to agree amongst 

themselves.

(iv) For portfolio swaps agreements (“PSA’s”) the seller will remain the seller 

regardless of the underlying’s performance.
122

(4) Commodity: 

(i) It is recognized within the commodities industry that different SDRs are currently 

proposing differing rules in determining the reporting counterparty. The 

methodology detailed below is the industry preferred and agreed way of working, 

as signed‐off by the GTRfC Commodities Industry WG.

(ii) Where both parties are of the same hierarchy level, reporting counterparty status 

may be determined by reference to the convention which is attached as 

Attachment 1 to this Annex 1. This convention requires the parties to apply a seller 

convention if the executed trade is one of the three trade types enumerated (which 

have no ambiguity concerning which party is the selling party) and designates the 

seller as reporting counterparty. If the trade to be executed is not one of the three 

specified trade types then the convention defaults to an alpha process the 

LEI/CiCi’s of the two parties should be resolved into an ASCii sorting tool with the 

LEI/Entity which comes first/top in the resulting list then designated as reporting 

counterparty.

(iii) Use of this convention can only be relied upon when both parties to the transaction 

are committed to use it. Where one side is not signed up to the convention it should 

not be used and the parties should revert to an alternative methodology to 

determine reporting counterparty in compliance with the rules.

(5) FX: 

The FX reporting counterparty rules have been defined by the GFMA Global FX Division’s 

Market Architecture Group (September 2012). The publication entitled “Determining the 

Reporting Party under Dodd‐Frank in the Foreign Exchange Market” sets out some 

suggested rules that participants may wish to consider for determining the reporting 

counterparty within a relevant hierarchy level, as well as setting out suggestions in respect 

of specific hierarchy cases not covered by the CFTC rules.
