Person has a direct or indirect substantial financial interest in the result of the deliberation or vote.

Individuals who are required to abstain from deliberations and voting pursuant to the above may participate

Rule 406 Execution of Swaps on CMSEF

The following are the acceptable methods CMSEF provides Participants in order to execute Swaps on 

CMSEF:

(i) Anonymous Central Limit Order Book (Minimum Functionality):

a. Acceptable Orders. The following kinds of orders may be entered into the Central Limit 

Order Book (CLOB) of the CMSEF Platform.

I. Limit Orders. A “Limit Order” is an order to buy or sell a contract at a specified 

price or better.

II. Market Orders. A “Market Order” is an order to purchase or sell a contract at the

best price on the CMSEF Platform at the time the order is entered on the CMSEF 

Platform (only available via fix API connection).

III. Fill or Kill. A “Fill or Kill” Order must be filled entirely or the Order is cancelled. 

IV. Immediate or Cancel. An “Immediate or Cancel” Order must be filled instantly 

or the Order is cancelled. 

b. Good until Time. An Order may be entered such that the Order is cancelled at a specific 

time if it is not executed (note that this feature is not available if accessing the system 

through the CMSEF website).

c. Entry of Orders. An anonymous order may be submitted directly by the Participant for its 

own account or on behalf of a Customer on whose behalf such a Participant is authorized 

to act. Each order on the CLOB must contain the following information:

I. Bid/Offer Indication

II. Price

III. Notional Amount 

IV. Instrument 

d. Time Delay Requirement. All Participants that are a broker or dealer and who, in 

connection with the execution of a Required Transaction, seek to either execute against a 

Customer’s order or execute two Customers against each other through the CMSEF’s 

CLOB shall use the following procedure:
CMSEF Rulebook CMSEF Page 27

I. If a Participant seeks to execute an order against a Customer order, then such 

Participant must enter the Customer order into the CMSEF CLOB and then wait 

at least 15 seconds before entering the Participant’s order; or

II. If a Participant seeks to execute two Customer orders against each other, then such 

Participant shall enter one side of the trade into the CMSEF CLOB and wait at 

least 15 seconds before entering the second side of the trade for execution.

e. Time Delay Exception. The time delay requirement does not apply to DMA Orders where 

a broker or dealer does not engage in some form of pre-arrangement or pre-negotiation of 

such order.

f. Price-Time Priority. All prices received in the CLOB are sorted based on strict price-time 

priority protocol.

g. Trading Limits. Participants shall only enter orders for such contracts and for such amounts 

as is permitted within the scope of their trading limits.

h. Matching of Orders. Orders submitted will be matched as follows:

I. Market Orders. Matching orders will be matched against all pending bids and 

offers in accordance with a price-time priority protocol. If any portion of the 

market order is not filled, the unfilled remainder will be canceled.

II. Limit Orders. Limit orders will be matched with bids and offers that have a price 

that is at or better than the price of the limit order, in accordance with the pricetime protocol. If any portion of the limit order is not filled, the unfilled portion of 

the order will remain in the market at the price and time that the order was entered. 

i. Unfilled Orders.

I. After the close of trading each Trading Day, all unfilled bids and offers will be 

cancelled

II. Upon a Participant’s logging out from the CMSEF Platform during the Trading 

Day, all unfilled bids and offers entered by such Participant will be cancelled.

j. Matching Algorithm. The CMSEF matching engine operates as a market order/limit order 

system. Orders are handled as follows:

I. Market orders are executed at the top of the market and can be matched with 

multiple standing orders at different prices if necessary to fill the market order 

volume;

II. Limit orders will execute at the requested price or better; and

III. Any unmatched limit order (or portion of an order) becomes a standing order in 

the system.

k. Counterparty Anonymity. 

I. Except as otherwise required under the Act or the Commission’s regulations, 

CMSEF shall not directly or indirectly, including through a third-party service 

provider, disclose the identity of a counterparty to a Swap that is executed 

anonymously and intended to be cleared.

II. It is prohibited for any Participant or Authorized User, directly or indirectly, 

including through a third-party service provider, to disclose the identity of a 

counterparty to a Swap that is executed anonymously and intended to be cleared.

III. For purposes of subsections I and II above, ‘‘executed anonymously’’ shall 

include a Swap that is pre-arranged or pre-negotiated anonymously, including by 

a Participant of CMSEF.

IV. For a package transaction that includes a component transaction that is not a Swap 

intended to be cleared, disclosing the identity of a counterparty shall not violate 

subsections I and II above. For purposes of this paragraph, a ‘‘package 

transaction’’ consists of two or more component transactions executed between 

two or more counterparties where:

1. Execution of each component transaction is contingent upon the 

execution of all other component transactions; and

2. The component transactions are priced or quoted together as one 

economic transaction with simultaneous or near-simultaneous execution 

of all components.
CMSEF Rulebook CMSEF Page 28

(ii) Request for Quote (RFQ)

a. Orders Entry. Participants may submit RFQ inquiries on a name disclosed basis. Unless 

the Participant is submitting an RFQ pursuant to Rule 416, submission of RFQ inquiries 

must be sent to minimum of three counterparties; none of which shall be: 

I. affiliated of or controlled by the counterparty requesting the RFQ inquiry; or 

II. affiliates of or controlled by each other.

b. Bids and Offers. At the same time that the requester receives the first responsive bid or 

offer, CMSEF shall communicate to the requester any firm bid or offer pertaining to the 

same instrument resting on the CLOB.

c. Responses. CMSEF shall provide the requester with the ability to execute against any firm 

CLOB bids or offers along with any responsive orders to the RFQ. 

d. Execution of Orders. The requester may accept any response to the RFQ upon receipt. 

After the requester accepts an RFQ, the responding party is given a “last look” in order to 

execute the Order. 

e. Trading Protocols. CMSEF will ensure that its trading protocols provide each Participant

with equal priority in receiving RFQs and in transmitting and displaying for execution 

responses to RFQs. 

f. Submitting a Request. Each RFQ shall include the following information regarding the 

Swap that the Participant is requesting quotes:

I. Product

II. Pay/Receive Indication

XV. Day Count Fraction

XVI. Clearing FCM 

g. Response to RFQ. Each response to an RFQ must contain a price.

h. Last Look. After the RFQ requester receives a quote, the requester will be able to execute. 

If the requester executes the quote, the Participant that submitted the quote will have a “last 

look” where such Participant will confirm the quote. The last look will expire in 30 seconds 

and until the Participant confirms the quote the requester may cancel the quote. 

Customer. The Customer requesting a quote on the RFQ system must be identified by the 

Participant entering the request, regardless if the Customer is the Participant or an 

Authorized User. 

(iii) Voice Order-Entry. A Participant may enter any order on the CLOB (Rule 406(i)) or RFQ 

(Rule 406(ii)) systems through communication with a Voice Agent. In this manner, any action 

that is permissible on the CLOB or RFQ may be taken on behalf of the Participant by the Voice 

Agent at the direction of the Participant.

(iv) Priorities of Orders: For any bid or offer on the CLOB, and for any RFQ or response to an 

RFQ, each Participant shall be given equal priority in terms of when such actions shall be 

displayed to the relevant Participants on CMSEF. Each order submitted on the SEF shall 

include the following:

a. The Legal Entity Identifier of the Participant or Client placing the order;

b. A yes/no indication of whether the Participant or Client is a swap dealer with respect to the 

product with respect to which the order is placed.
CMSEF Rulebook CMSEF Page 29

c. A yes/no indication of whether the Participant or Client is a major swap participant with 

respect to the product with respect to which the order is placed.

d. A yes/no indication of whether the Participant or Client is a Financial Entity.

e. A yes/no indication of whether the Participant or Client is a U.S. Person.

f. If applicable, an indication that the Participant or Client will elect the clearing requirement 

exception in CEA section (2)(h)(7) for any swap resulting from the order.

(v) Brokered Orders: Participants may enter an Order through a Registered Broker for which the 

Participant has entered into an agreement that permits the Registered Broker to act on behalf of 

the Participant. Such Order are treated as if the Order was entered directly by the Participant, 

under the rules of CMSEF.

Rule 407A Required Transactions

Required Transactions that do not qualify as a Block Trade or a Clearing Exception shall be executed on CMSEF 

according to Rule 406.

Rule 407B Permitted Transactions

Permitted Transactions shall be executed on CMSEF according to Rule 406, with the following qualifications:

(ii) Permitted Transactions negotiated off-SEF may be entered for execution and clearing by the 

staff of the SEF directly, at the direction of a Registered Broker. 

Rule 407C Clearing Exception for Swaps 

Each Participant wishing to execute an Order under a Clearing Exception on CMSEF must submit all 

documentation required by Part 50 of the CFTC Regulations (the Clearing Exception Form) prior to placing 

an Order subject to the Clearing Exception. A Participant shall submit all required documentation supporting 

its eligibility (or the eligibility of its relevant Authorized User, as applicable) for the Clearing Exception. 

Any Order subject to the Clearing Exception shall be rejected if an applicable Clearing Exception Form is 

not on file with CMSEF. 

The Clearing Exception may only be used for Orders that are not executed on the CLOB. 

Rule 408 Cancellation of Orders by Participants

Participants may cancel any Order that has been entered on CMSEF, unless it has been executed or has 

expired. 

Rule 409 Modification or Cancellation of Orders and Trades by CMSEF

Before an Order is sent to a Clearinghouse, CMSEF may cancel any Order that, if allowed to remain, would 

have meaningful adverse effects on the integrity of the market, if the Order is entered in a price outside a 

range known as the Acceptable Price Range, or a CMSEF system malfunction. The Acceptable Price Range 

shall be determined by CMSEF based on the market data available to CMSEF. It may change from time to 

time and shall be published on the CMSEF website. 

Once a trade has been cleared by a Clearinghouse, CMSEF may adjust trade prices or cancel if there is a 

CMSEF system malfunction or with the consent of both Counterparties. Such modification or cancellation 

shall be effected by a pre-arranged trade or trades, consistent with CFTC No-Action Letter No. 15-24

(published by the CFTC on April 22, 2015; relief last extended May 30, 2017). 
CMSEF Rulebook CMSEF Page 30

At any time, CMSEF may halt or suspend trading on its platform in order to maintain a fair and orderly 

market, as required by these Rules. Any halt or suspension in trading shall be communicated to Participants 

as soon as practicable. 

If CMSEF takes action pursuant to this Rule, it will give prompt notice to affected Participant or Participants. 

Rule 410A Pre-Execution Credit Checks

CMSEF will verify prior to the execution of any Order that the Participants or Authorized User have sufficient 

credit limits with their Clearing Members so that the trade will be able to be accepted by the Clearing House 

for Clearing. CMSEF will not permit Participants or Authorized User to execute transactions if their credit 

limits are insufficient. 

All Orders will be prescreened on an order-by-order basis. A Clearing Member may reject an Order preexecution or post-execution. If an Order is rejected by the Clearing Member post-execution, such Order shall 

be void ab initio.

It is the responsibility of the Participants or Authorized User to evaluate the credit quality of their Prime 

Broker, FCM, and/or Clearinghouse, and their counterparty on uncleared swaps.

Rule 410B Confirmation of Agreements Between Counterparties

The terms of the Swap, which shall serve as a confirmation of the transaction, will be sent at the time of 

execution of the Swap. Specifically, upon the execution of a Swap, CMSEF will provide each counterparty 

to a transaction that is entered into on or pursuant to the rules of the SEF with a written record of all of the 

terms of the Swap, which shall legally supersede any previous agreement and serve as a confirmation of the 

transaction; provided, that specific Customer identifiers for accounts included in bunched orders involving 

Swaps will not be included in confirmations provided by CMSEF if the applicable requirements of CFTC 

Regulation 1.35(b)(5) are met. Confirmations of Swaps delivered to counterparties shall not include any 

information that violates Rule 406(i)(k).

Rule 411 Cleared Swaps

The following does not apply with respect to swaps subject to the clearing requirement exception in CEA 

section (2)(h)(7) for which a counterparty has elected such exception. 

Each Cleared Swap shall be cleared through the Clearing House indicated in the Swap Specification in 

accordance with the CEA and the CFTC Regulations.

For each Cleared Swap a Participant expects to enter into via the SEF Platform or subject to CMSEF Rules, 

the Participant or a Client or Customer of the Participant must establish a clearing account with the Clearing 

House or with a Clearing Member of the Clearing House, in each case, designated in the Swap Specification 

for such Cleared Swap.

Submission of executed trades to the applicable DCO shall be the responsibility of CMSEF.

of the facility, as is deemed necessary and appropriate by SEF, position limitations or position accountability 

levels for speculators.

(v) Block Trades executed off CMSEF must be reported by the Participants to CMSEF as soon as 

practicable but no later than five (5) minutes before the time such Block Trade would be reported 

by an SDR. The actual notional or principal amount of the Block Trade shall be reported to CMSEF, 

which shall report the Block Trade as set forth in CFTC Regulation 43.6 and Appendices B, D, E, 

and F to Part 43 of the CFTC Regulations. 

CMSEF reserves the right to investigate all Block Trades to ensure that they comply with all applicable 

CMSEF Rules and CFTC Regulations.

A Participant transacting a Block Trade on behalf of a Customer must receive prior written instruction or 

consent from the Customer in order to do so. Such instruction or consent may be provided in the power of 

attorney or similar document by which the customer provides the person with discretionary trading authority 

or authority to direct the trading in its account.

The parties to a publicly reportable swap transaction on CMSEF that has a notional amount at or above the 

appropriate minimum block size shall notify CMSEF of its election to have the publicly reportable swap 

transaction treated as a Block Trade. CMSEF, pursuant to these Rules, shall notify the SDR of such a Block 
CMSEF Rulebook CMSEF Page 33

Trade election when transmitting swap transaction and pricing data to such SDR in accordance with CFTC 

Regulation 43.3(b)(1).

Rule 416B Execution of Block Trades Through RFQ

Block Trades shall only be executed on CMSEF using the RFQ system, and only if the conditions of CFTC 

No-Action Letter No. 15-60 (published by the CFTC on November 2, 2015; relief expires November 15, 

2016) are met. These requirements are as follows:

(i) the Block Trade must meet the definition found in this Rulebook, and must be executed under 

the Rules of CMSEF;

(ii) a pre-trade credit check must be completed at the time the order for a block trade enters the 

Block Trade on the RFQ system; and

(iii) all Block Trades are subject to void ab initio requirements if swap is rejected on the basis of 

credit. 

Rule 417A Pre-Trade Communications

A Participant or Authorized User, acting on behalf of a Customer, must have the Customer’s consent before 

engaging in pre-arrangement communication with a counterparty. The Participant or Authorized User may 

not disclose such communications to any third party and may not use such communications to enter into 

alternative transactions other than the transaction permitted by this Rule. In any case in which a transaction 

is agreed upon as the result of pre-arrangement communication, the Participant or Participants must allow a 

15-second delay between orders entered on the SEF. There is no mechanism on the CMSEF system that 

prevents a trade from being submitted before such 15-second delay has occurred and therefore any applicable 

Order that is executed without the delay shall be a violation of these Rules and CFTC Regulations. 

Rule 417B Information Obtained in Pre-Trade Communications

All Participants or Authorized Users party to the pre-arrangement communication permitted by Rule 417A 

are prohibited from disclosing such communications to any third party and may not use such communications 

to enter into alternative transactions other than the transaction permitted by this rule.

Rule 418A Dissemination of Prices and Trading Information

CMSEF shall publish information daily on its website regarding prices, volume, and other data as required 

by the CFTC Regulations. 

CMSEF will also make available a central pricing screen on CMSEF with a real-time view of resting bids 

and offers.

CMSEF may make available to Participants an indicative, non-attributed pricing page on CMSEF for certain 

types of Swaps of the most commonly traded tenors within such type of Swap.

CMSEF shall choose, at its sole discretion, an SDR. As required by CFTC Regulation 37.901(a), CMSEF 

shall transmit swap transaction and pricing data for each Swap executed pursuant to these Rules to the 

appropriate SDR in the form and manner required. At this time, all trades on CMSEF will be reported to 

DTCC Data Repository (U.S.) LLC.

CMSEF may provide such swap transaction and pricing data to Participants and Authorized Users no earlier 

than the time it transmits such information to an SDR and in a form that does not disclose the identities, or 

otherwise facilitate identification, of the parties to the Swap.

Rule 418B Publicly Reportable Swap Transactions 
CMSEF Rulebook CMSEF Page 34

Pursuant to Part 43 and Appendix A to Part 43 of the CFTC Regulations and Part 45 and Appendix 1 to Part 

45 of the CFTC Regulations, CMSEF shall transmit swap transaction and pricing data and minimum primary 

economic terms to a registered SDR as soon as technologically practicable after the publicly reportable swap 

transaction has been executed on or pursuant to the rules of CMSEF.

CMSEF and Participants shall not submit or agree to submit a cancellation or correction for the purpose 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 in Part 43 of the 

CFTC Regulations. 

Rule 418C Reporting Counterparties 

For all swaps executed on CMSEF, each swap counterparty shall provide sufficient information to CMSEF 

to enable CMSEF to report all Required Swap Creation Data to enable CMSEF to report all Required Swap 

Creation Data. To achieve this, each Participant placing an order with respect to any Swap traded on CMSEF 

must include in the order the information required by CMSEF Rule 406(iii). 

In the event that the Reporting Counterparty cannot otherwise be determined because either (a) both 

counterparties are swap dealers, (b) both counterparties are major swap participants, (c) both counterparties 

are a financial entities as defined by Section 2(h)(7)(C) of the CEA but not a swap dealer or a major swap 

participant, or (d) both counterparties are neither a swap dealer nor a major swap participants nor a financial 

entity as defined by Section 2(h)(7)(C) of the CEA, then the reporting counterparty shall be the buyer. 

All Reporting Counterparties are required to notify CMSEF in the event the Reporting Counterparty becomes 

aware that an error or omission in reporting has occurred. 

Rule 419 Emergency Rules

In the event of an Emergency, CMSEF may implement temporary Emergency procedures and Emergency 

Rules, subject to the applicable provisions of the CEA and CFTC Regulations. Implementation of Emergency 

Rules shall be done in consultation with the CFTC. Emergency Rules may require or authorize CMSEF, the 

Board, any committee of the Board, the President, or any other Officer to take actions necessary or 

appropriate to respond to the Emergency, including the following actions: 

(i) suspending or curtailing trading or limiting trading to liquidation only (in whole or in part)

(ii) extending or shortening the last trading date for Swaps; 

(iii) ordering the fixing of a settlement price; 

(iv) ordering the liquidation or transfer of an open position in any Swap, or the 

(v) reduction of positions; 

(vi) extending, limiting or changing the Trading Hours; 

(vii) imposing or modifying intraday market restrictions; 

(viii) transferring Customer contracts and the margin in an Emergency; 

(ix) imposing special margin requirements; 

(x) extending or shortening the expiration date of a Swap; 

(xi) altering any Swap’s settlement terms and conditions; 

(xii) imposing or modifying price limits; and/or

(xiii) imposing, modifying or reducing position limits.

Before any Emergency Rule may be adopted and enforced, a required vote of the Board must approve the 

implementation of such Emergency Rule at a duly convened meeting requested by the President or any other 

Officer. Directors may attend such a meeting by teleconference. Each Director participating in such meeting 

shall be subject to CMSEF’s Conflict of Interest Rules. If the CEO or CMSEF determines that Emergency 

Rules must be implemented with respect to an Emergency before a meeting of the Board can reasonably be 
CMSEF Rulebook CMSEF Page 35

convened, then the CEO shall have the authority, without Board action, to implement any Emergency Rules 

with respect to such Emergency that he or she deems necessary or appropriate to respond to such Emergency. 

Whenever CMSEF, the Board, any committee of the Board, or the President takes actions necessary or 

appropriate to respond to an Emergency (including the actions set forth above), an Authorized Representative 

of CMSEF will post a Notice to Participants regarding such Emergency, as soon as practicable. When the 

Board, any committee of the Board or the CEO determines that the Emergency is no longer in effect, 

permitting the SEF operated by CMSEF to resume normal functioning; any such actions responding to an 

Emergency will be terminated. 

CMSEF will use reasonable efforts to notify the CFTC prior to implementing, modifying or terminating an 

Emergency Rule. If such prior notification is not possible or practicable, CMSEF will notify the CFTC as 

soon as possible or reasonably practicable, but in all circumstances within twenty-four (24) hours of the 

implementation, modification or termination of such Emergency Rule. 

Upon taking any action in response to an Emergency, CMSEF will document the decision-making process 

related to such action. Such documentation will be kept for at least five years following the date on which 

the Emergency ceases to exist or to affect the SEF operated by CMSEF, and all such documentation will be 

provided to the CFTC upon request. 

Chapter 5 Disciplinary Rules

Rule 501 General 

All Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers 

shall be subject to the CMSEF’s jurisdiction. Participants, Authorized Persons, Authorized Users, Clearing 

Members, and Participant’s Customers are subject to this Chapter 5 if they, or with respect to a Participant, 

any other Person using any of its User IDs, are alleged to have violated, or to have aided and abetted a 

violation of, or are about to violate, any Rule or any provision of applicable law for which CMSEF possesses 

disciplinary jurisdiction. 

CMSEF, through its Compliance Department and the Disciplinary Panel, will conduct Investigations, 

Disciplinary Proceedings and appeals from Disciplinary Proceedings, summary impositions of fines, 

summary suspensions or other summary actions in accordance with this Chapter. 

No CMSEF member of the Board, Officer, Employee, or Agent will interfere or attempt to interfere with any 

Investigation, disciplinary hearing, or summary imposition of a judgment or other summary action.

CMSEF shall permit Participants, Authorized Persons, Authorized Users, Clearing Members, or Participant’s 

Customers to be represented by counsel during any Investigation, disciplinary hearing, or imposition of a 

fine or summary judgment.

CMSEF may hold a Participant or Authorized User liable for, and impose sanctions against such Participant 

or Authorized User for such Person’s own acts and omissions, or those of its agents, representatives or any 

Person or API using a User ID of such Participant or Authorized User. CMSEF may additionally hold a 

Participant liable for the acts and omissions of its Authorized Users. 

CMSEF may delegate any or all of its powers or responsibilities under this Chapter 5 to the RSP, which may 

take any action on behalf CMSEF that the CMSEF is permitted to take hereunder; provided, however, that 

the CMSEF shall retain supervisory authority with respect to such powers and responsibilities and will 

document instances where its actions differ in any material respect from those recommended by the RSP. 

Rule 502 CMSEF’s Right to Inspect Books, Records and Systems
CMSEF Rulebook CMSEF Page 36

CMSEF’s Compliance Department and CMSEF’s RSP (if any) will have the right to inspect the books, 

records, systems, equipment, and software of Participants, Authorized Persons, Authorized Users, Clearing 

Members and Participant’s Customers.

CMSEF’s Compliance Department and CMSEF’s RSP (if any) will have the right to obtain position and 

trading information directly from Participants as necessary to perform CMSEF’s Oversight functions as set 

forth in this Rulebook. 

Rule 503 Investigations

CMSEF’s Compliance Department or Disciplinary Panels will investigate any matter within CMSEF’s 

disciplinary jurisdiction of which it becomes aware. The Compliance Department will determine the nature 

and scope of its Investigations within its sole discretion and will function independently of any commercial 

interests of CMSEF. An Investigation will be initiated if the Compliance Department or other CMSEF 

Departments determines that a violation of CMSEF may have occurred. The Compliance Department may 

informally contact Participants in order to obtain information. 

Notwithstanding the above, CMSEF will commence an Investigation at the request of the CFTC. 

CMSEF’s Compliance Department has the authority to: 

(i) initiate and conduct Investigations; 

(ii) prepare Investigation Reports and make recommendations concerning initiating Disciplinary 

Proceedings; 

(iii) allege violations within CMSEF’s disciplinary jurisdiction; 

(iv) prosecute alleged violations within CMSEF’s disciplinary jurisdiction; and

(v) represent CMSEF on an appeal to an Appeal Panel of any Disciplinary Proceeding, summary 

imposition of fines, summary suspension or other summary action. 

Each Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers: 

(i) is obligated to appear, testify and respond in writing to interrogatories within the time 

period required by the Compliance Department in connection with any Rule, any 

Investigation; or any preparation by and presentation during a Disciplinary Proceeding or 

appeal from a decision in a Disciplinary Proceeding, summary imposition of fines, 

summary suspension or other summary action by CMSEF; 

(ii) is obligated to produce books, records, papers, documents or other tangible evidence in his 

possession, custody or control within the time period required by the Compliance 

Department in connection with any Rule, any Investigation, any preparation by and 

presentation during a Disciplinary Proceeding or appeal from a decision in any Disciplinary 

Proceeding, summary imposition of fines, summary suspension or other summary action 

by CMSEF; and 

(iii) may not impede or delay any Investigation, Disciplinary Proceeding, appeal from a 

Disciplinary Proceeding, summary imposition of fines, summary suspension or other 

summary action. 

Rule 504 Reports of Investigations 

CMSEF’s Compliance Department will maintain a log of all Investigations and their disposition. The 

Compliance Department will prepare a written report of each Investigation (the “Investigation Report”), 

regardless of whether the evidence gathered during any Investigation forms a reasonable basis to believe that 

a violation within CMSEF’s jurisdiction has occurred or is about to occur or whether the evidence gathered 

results in closing the matter without further action or through summary action. 

Any Investigation Report will include the reasons for initiating the Investigation (including a summary of the 

complaint, if any), all relevant facts and evidence gathered and the analysis, conclusions and recommendation 

of the Compliance Department. For each potential respondent, the Compliance Department will recommend 

either: 
CMSEF Rulebook CMSEF Page 37

(i) closing the Investigation without further action; 

(ii) entering into a summary action;

(iii) resolving the Investigation through an informal disposition, including the issuance by the 

Compliance Department of a warning letter (provided that no more than one warning letter for 

the same violation may be issued to the same potential respondent during a rolling 12-month 

period);

(iv) initiating Disciplinary Proceedings; or 

(v) negotiating a settlement. 

An informal disposition (including the issuance of a warning letter by the Compliance Department) will not 

constitute a finding of a violation or a sanction. 

CMSEF’s Compliance Department shall provide the Investigation Report to the Chief Compliance Officer, 

who shall determine whether the Investigation Report is complete.

CMSEF’s Compliance Department shall complete each Investigation in a timely manner and, absent 

mitigating factors, no later than 12 months after the date that such Investigation was opened. 

Rule 505 Opportunity to Respond to Investigation Reports 

After completing the Investigation Report, if the evidence gathered during an Investigation forms a 

reasonable basis to believe that a violation within CMSEF’s jurisdiction has occurred or is about to occur,

CMSEF’s Compliance Department may, upon approval of the Chief Compliance Officer, notify each 

potential respondent that the Compliance Department has recommended formal disciplinary charges against 

each such potential respondent. 

The potential respondents shall be notified in writing and shall have fourteen days to respond, unless 

extenuating circumstances require a response sooner.

CMSEF’s Compliance Department may allow a potential respondent to propose a settlement of the matter or 

to submit a written statement explaining why either a Disciplinary Proceeding should not be instituted or one 

or more of the potential charges should not be brought. The potential respondent shall submit such written 

statement within the time limit established by the Compliance Department. 

Rule 506 Review of Investigation Reports 

CMSEF’s Compliance Department will, within 30 days, take one of the following actions: 

(i) If CMSEF’s Compliance Department determines that no reasonable basis exists to believe that a 

violation within CMSEF’s jurisdiction has occurred or is about to occur, it may direct that no 

further action be taken. Upon such determination, the Compliance Department will provide a 

written statement setting forth the facts and analysis supporting the decision. 

(ii) If CMSEF’s Compliance Department determines that Disciplinary Proceedings are unwarranted, it 

may issue a warning letter setting forth, in writing, the facts and analysis supporting the decision. 

(iii) If CMSEF’s Compliance Department determines that additional inquiries or evidence is needed to 

decide whether a reasonable basis exists to believe that a violation within CMSEF’s jurisdiction 

has occurred or is about to occur, it will continue the Investigation. 

(iv) If CMSEF’s Compliance Department determines that a reasonable basis exists to believe that a 

violation within CMSEF’s jurisdiction has occurred or is about to occur, the potential respondent 

will be served with a notice of charges and proceed in accordance with this Chapter 5. 

Rule 507 Warnings
CMSEF Rulebook CMSEF Page 38

CMSEF’s Compliance Department is authorized to issue a warning letter to an individual or entity subject 

to an Investigation. If a warning letter is issued by the CMSEF’s Compliance Department, it shall not be 

considered an indication that a violation has occurred. Only one warning letter may be issued to the same 

individual or entity per violation per year.

Rule 508 Notice of Charges 

If CMSEF’s Compliance Department authorizes Disciplinary Proceedings pursuant to these Rules, it will 

prepare, and serve in accordance with these Rules, a notice of charges. 

A notice of charges will: 

(i) state the acts, practices or conduct in which the respondent is alleged to have engaged; 

(ii) state the Rule alleged to have been violated or about to be violated; 

(iii) advise the respondent of its right to a hearing and its right to be represented by legal counsel 

or any other representative of its choosing (other than a Director, Officer or Employee of 

CMSEF, any member of the Disciplinary Panel or any Person substantially related to the 

Disciplinary Proceedings such as a material witness or other respondent) in all succeeding 

stages of the disciplinary process; 

(iv) state the period of time within which the respondent can request a hearing on the notice of 

charges, which will not be less than 20 days after service of the notice of charges; 

(v) advise the respondent that any failure to request a hearing within the period stated, except 

for good cause, will be deemed to constitute a waiver of the right to a hearing; and 

(vi) advise the respondent that any allegation in the notice of charges that is not expressly 

denied will be deemed to be admitted. 

Rule 509 Service of Notice of Charges 

CMSEF shall serve notice of charges or other documents contemplated to be served pursuant to this Chapter 

5 to a contact designated by each Participant. CMSEF may serve such notice (and service shall be deemed 

complete) to the respondent personally, or by deposit in the United States mail, postage prepaid, via registered 

or certified mail addressed to the respondent at the address as it appears in records of CMSEF. Notice of 

Charges may also be served by electronic mail to the respondent’s electronic mail address as it appears on 

the books and records of CMSEF, if followed by a hard copy of the document sent promptly thereafter by 

registered or certified mail addressed to the respondent at the respondent’s address as it appears in records of 

CMSEF. 

Rule 510 Answer to Notice of Charges 

If the respondent determines to answer a notice of charges, the respondent must file an answer within 20 days 

after being served with such notice, or within such other time period determined appropriate by the Chief 

Compliance Officer. 

To answer a notice of charges, the respondent must in writing: 

(i) for each allegation set forth in the notice of charges, admit such allegation, deny such 

allegation, or affirmatively state that the respondent does not have and is unable to obtain 

sufficient information to admit or deny such allegation, which shall have the effect of a 

denial of such allegation; 

(ii) specify any specific facts that contradict the notice of charges; 

(iv) specify any affirmative defenses to the notice of charges; 

(iv) sign and serve the answer on the Chief Compliance Officer; and 

(v) if applicable, request a hearing before a Disciplinary Panel. 

Any failure by the respondent to serve a timely answer to a notice of charges will be deemed to be an 

admission to the allegations in such notice. Any failure by the respondent to answer one or more allegations 

in a notice of charges will be deemed to be an admission of that allegation or those allegations. Any allegation 
CMSEF Rulebook CMSEF Page 39

in a notice of charges that the respondent fails to deny will be deemed to be admitted. A general denial by 

the respondent, without more, will not satisfy the requirements of the second paragraph of this Rule. 

If a respondent admits or fails to specifically deny any of the allegations in the notice of charges, the 

Disciplinary Panel shall find that the violations set forth in such allegations have been committed and shall 

impose a sanction for such violations. The Disciplinary Panel shall promptly notify the respondent in writing 

of any sanction imposed pursuant to this Rule and advise the respondent that the respondent may request a 

hearing on such sanction within 20 days of the respondent being served with such notice. Any failure by the 

respondent to do so will be deemed to be an acceptance of the sanctions in such notice and waiver of any 

right to appeal such sanctions. 

A respondent shall be granted a hearing before a Disciplinary Panel for every instance in which such 

respondent either denies an allegation and requests a hearing in accordance with this Rule; or requests a 

hearing in accordance with this Rule.

Rule 511 Right to a Hearing

All respondents who have denied a charge shall be afforded the opportunity for a hearing. The hearing 

must concern only those charges, which the respondent has denied.

Rule 512 Settlements 

A respondent or potential respondent may at any time propose in writing an offer of settlement to anticipated 

or instituted Disciplinary Proceedings. Any offer of settlement should contain proposed findings and 

sanctions and be signed by the respondent or potential respondent and submitted to the Compliance 

Department, and shall take into account, among other things, the disciplinary history of the respondent or 

potential respondent. A respondent or potential respondent may offer to settle Disciplinary Proceedings 

without admitting or denying the findings contained in the order of the Disciplinary Proceedings but must 

accept the jurisdiction of CMSEF over it and over the subject matter of the proceedings and consent to the 

entry of the findings and sanctions imposed. 

If a respondent or potential respondent submits an offer of settlement in accordance with paragraph (a) of 

this Rule, the Compliance Department will forward the offer to the Disciplinary Panel with a recommendation 

on whether to accept or reject the offer. The respondent or potential respondent may withdraw such offer of 

settlement at any time before acceptance by the Disciplinary Panel, but may not withdraw such offer at any 

time after acceptance by the Disciplinary Panel. 

The Disciplinary Panel may accept the offer of settlement, but may not alter the terms of a settlement offer 

unless the respondent or potential respondent agrees. 

If an offer of settlement is accepted by the Disciplinary Panel, it shall issue a written decision specifying: 

(i) the Rule violations it has reason to believe were committed, including the basis or reasons 

for its conclusions; 

(ii) any sanction to be imposed, which must include full Customer restitution where Customer

harm has been demonstrated; and 

(iii) if applicable, that the respondent has accepted the sanctions imposed without either 

admitting or denying the Rule violations. 

In the event that the Disciplinary Panel accepts an offer of settlement without the agreement of the 

Compliance Department, the decision must adequately support such acceptance. 

If an offer of settlement is accepted and the related order of Disciplinary Proceedings becomes final, the 

respondent’s submission of the offer will be deemed to constitute a waiver of the right to notice, opportunity 

for a hearing and review and appeal under these Rules. 
CMSEF Rulebook CMSEF Page 40

If the offer of settlement of a respondent or potential respondent is not accepted by the Disciplinary Panel, 

fails to become final or is withdrawn by the respondent or potential respondent before its acceptance by the 

Disciplinary Panel, the matter will proceed as if the offer had not been made and the offer and all documents 

relating to it will not become part of the record. Neither a respondent or potential respondent nor the 

Compliance Department may use an unaccepted offer of settlement as an admission or in any other manner 

at a hearing of, or appeal from, Disciplinary Proceedings. 

Rule 513 Disciplinary Panels 

The Disciplinary Panel shall conduct hearings in connection with any Disciplinary Proceedings (except for 

summary impositions of fines pursuant to these Rules), to make findings, render decisions, and impose 

sanctions pursuant to this Chapter 5. 

Each Disciplinary Panel shall be composed of three individuals selected by the Chief Compliance Officer. 

Except in cases limited to the timely submission of accurate records, each Disciplinary Panel shall consist of 

an individual who would not be disqualified from serving as a Public Director, who shall chair the 

Disciplinary Panel. 

No member of the Compliance Department may serve on a Disciplinary Panel. 

Except as may otherwise be provided in these Rules, the Board may at any time remove any member of a 

Disciplinary Panel for cause. 

Within 10 days of being notified of the appointment of the Disciplinary Panel, a respondent may seek to 

disqualify any individual named to the Disciplinary Panel for the reasons identified in these Rules, by serving 

written notice on the Chief Compliance Officer and providing a copy thereof to the chairman of the 

Disciplinary Panel. By not timely filing a request for disqualification, the respondent will be deemed to have 

waived any objection to the composition of a Disciplinary Panel. The Chief Compliance Officer will decide 

in his sole discretion the merits of any request for disqualification. Any such decision will be final and not 

subject to appeal. 

All information, records, materials and documents provided to the Disciplinary Panel and all deliberations, 

testimony, information, records, materials and documents related thereto shall be treated as non-public and 

confidential and shall not be disclosed, except as necessary to further an Investigation or as otherwise required 

by law. No individual shall serve on a Disciplinary Panel unless that individual has agreed in writing that he 

will not publish, divulge, or make known in any manner facts or information regarding the business of any 

Person or other information which may come to his or her attention in his official capacity as a member of 

the Disciplinary Panel, except:

a. when reporting to the Board or to a Standing Committee concerned with such 

information;

b. when reporting to the Compliance Department;

c. when requested by the CFTC or other government agency; or 

d. when compelled to testify in any judicial or administrative proceeding. 

Rule 514 Convening Hearings of Disciplinary Proceedings 

All Disciplinary Proceedings (except for summary impositions of fines pursuant to these Rules) will be 

conducted at a hearing before a Disciplinary Panel. Hearings will be conducted fairly, privately and 

confidentially. Notwithstanding the confidentiality of hearings, the Disciplinary Panel may appoint an expert 

to attend any hearing and assist in deliberations if such expert agrees to be subject to an appropriate 

confidentiality agreement. 

After reasonable notice to each respondent, the Disciplinary Panel will promptly convene a hearing to 

conduct the Disciplinary Proceedings with respect to such respondent. Parties to a Disciplinary Proceeding

include each respondent and the Compliance Department. 
CMSEF Rulebook CMSEF Page 41

The chairman of the Disciplinary Panel may continue, adjourn or otherwise conduct the hearing, as he may 

deem appropriate. The chairman of the Disciplinary Panel will determine all procedural and evidentiary 

matters, including the admissibility and relevance of any evidence proffered. In determining procedural and 

evidentiary matters, the chairman of the Disciplinary Panel will not be bound by any evidentiary or procedural 

rules of law. Once admitted during the hearing, the Disciplinary Panel may consider, and attach the weight 

it believes appropriate to, evidence or other materials. CMSEF’s Legal Department will provide guidance to 

the chairman of the Disciplinary Panel on the conduct of the hearing. 

Except for procedural and evidentiary matters decided by the chairman of the Disciplinary Panel pursuant to 

these Rules, unless each respondent otherwise consents, the entire Disciplinary Panel must be present during 

the entire hearing and any related deliberations. 

Rule 515 Respondent Review of Evidence 

Prior to the commencement of a hearing, each respondent will be given the opportunity, subject to the sections 

below, to review all books, records, documents, papers, transcripts of testimony and other tangible evidence 

in the possession or under the control of CMSEF that the Compliance Department will use to support the 

allegations and proposed sanctions in the notice of charges or which the chairman of the Disciplinary Panel 

deems relevant to the Disciplinary Proceedings. Notwithstanding the foregoing, no respondent will have the 

right to review, and CMSEF will have no obligation to disclose, any information protected by attorney-client 

privilege. All requests for such information must be made not less than 10 days prior to the scheduled hearing 

date, unless the chairman of the Disciplinary Panel agrees otherwise. 

If any books, records, documents, papers, transcripts of testimony, or other tangible evidence contain 

information that could adversely affect the competitive position of the Person providing the information or 

if such information might compromise other Investigations being conducted by the Compliance Department, 

the Compliance Department may redact, edit or code such information before furnishing it to the respondent. 

Notwithstanding anything in this Rule to the contrary, the Compliance Department: 

(i) will not redact, edit or code competitive or investigative information contained in 

documents in a manner that would materially impair the respondent’s ability to defend 

against the allegations or proposed sanctions in the notices of charges, and 

(ii) will provide the respondent with access to the information and portions of the documents 

that the Compliance Department intends to rely on to support the allegations or proposed 

sanctions in the notice of charges. 

For purposes of these Rules, information that could adversely affect competitive positions includes positions 

in Swaps currently held, trading strategies employed in establishing or liquidating positions, the identity of 

any Participant or Authorized User and the personal finances of the Person providing the information. 

The respondent shall treat as confidential all data and information provided to it pursuant to these Rules, and 

shall not disclose any such data or information, except as necessary to the respondent’s defense of notice of 

charges and any appeal of the decision of the Disciplinary Panel.

Rule 516 Conducting Hearings of Disciplinary Proceedings 

At a hearing conducted in connection with any Disciplinary Proceedings, the Compliance Department will 

present its case supporting the allegations and proposed sanctions in the notice of charges to the Disciplinary 

Panel. If a respondent has timely filed an answer to the notice of charges in accordance with these Rules, the 

respondent is entitled to attend and participate in the hearing. 

At a hearing conducted in connection with any Disciplinary Proceedings, the Compliance Department and 

each respondent may: 

(i) present evidence and facts determined relevant and admissible by the chairman of the 

Disciplinary Panel; 

(ii) call and examine witnesses; and 
CMSEF Rulebook CMSEF Page 42

(iii) cross-examine witnesses called by other parties. 

If the respondent fails to file an answer, has filed a general denial, or if any or all of the allegations in the 

notice of charges are not expressly denied in the respondent’s answer, the chairman of the Disciplinary Panel 

may limit evidence concerning any allegations not expressly denied in determining the sanctions to impose. 

If a respondent fails to file an answer but appears at the hearing, the respondent may not participate in the 

hearing (by calling or cross-examining witnesses, testifying in defense, presenting evidence concerning the 

notice of charges, or otherwise) unless the Disciplinary Panel determines that the respondent had a 

compelling reason for failing to file a timely answer. If the Disciplinary Panel determines that the respondent 

had a compelling reason for failing to file a timely answer, the Disciplinary Panel will adjourn the hearing 

and direct the respondent to promptly file the written answer in accordance with these Rules. 

Any Person entitled, or required or called upon, to attend a hearing before a Disciplinary Panel pursuant to 

this Rule will be given reasonable notice, confirmed in writing, specifying the date, time and place of the 

hearing, and the caption of the Disciplinary Proceedings. CMSEF will require all Authorized Persons and 

Authorized Users that are called as witnesses to appear at the hearing and produce evidence. CMSEF will 

make reasonable efforts to secure the presence of all other Persons called as witnesses whose testimony would 

be relevant. 

If during any Disciplinary Proceedings the Disciplinary Panel determines that a reasonable basis exists to 

believe that the respondent violated a Rule or a provision of applicable law other than the violations alleged 

in the notice of charges, the Disciplinary Panel may consider those apparent violations after providing the 

respondent with an opportunity to answer the additional allegations in accordance with these Rules. In 

connection with considering apparent violations pursuant to this Rule, the Disciplinary Panel may request 

that the Compliance Department provide the Disciplinary Panel with any additional information. 

The Disciplinary Panel may summarily impose sanctions on any Participant, Authorized Person, or 

Authorized User that impedes or delays the progress of a hearing. 

CMSEF will arrange for any hearing conducted in connection with Disciplinary Proceedings to be recorded 

hearing verbatim, or substantially verbatim, in a manner capable of accurate transcription. The record shall 

not be transcribed unless requested by CTFC staff or the respondent or the decision is appealed. If the 

respondent requests a copy of all or portions of the recording of a hearing, the chairman of the Disciplinary 

Panel may within his sole discretion order the respondent to pay the costs for transcribing the recording of 

the hearing. 

No interlocutory appeals of rulings of any Disciplinary Panel or chairman of the Disciplinary Panel are 

permitted. 

Rule 517 Decision of Disciplinary Panel 

As promptly as reasonable following a hearing, the Disciplinary Panel will issue an order rendering its 

decision based on the weight of the evidence contained in the record of the Disciplinary Proceedings. A 

decision by a majority of the Disciplinary Panel will constitute the decision of the Disciplinary Panel. 

CMSEF will serve a copy of the order of the Disciplinary Panel on the respondent and the Compliance 

Department. The order will include: 

(i) the notice of charges or summary of the allegations; 

(ii) the answer, if any, or a summary of the answer; 

(iii) a brief summary of the evidence introduced at the hearing (or, where appropriate, incorporation 

by reference of the Investigation Report); 

(iv) findings of fact and conclusions concerning each allegation, including each specific Rule that 

the respondent is found to have violated; 

(v) the imposition of sanctions, if any, the basis for the sanctions, and effective date of each 

sanction; and 

(vi) notice of the respondent’s right to appeal pursuant to these Rules. 
CMSEF Rulebook CMSEF Page 43

A Disciplinary Panel shall be dissolved automatically when it has decided the matter for which it was 

appointed and has notified the respondent and the Chief Compliance Officer in writing of its decision. 

Unless a timely notice of appeal is filed pursuant to these Rules, the order of the Disciplinary Panel will 

become final upon the expiration of 20 days after the order is served on the respondent and a copy thereof is 

provided to the Compliance Department. 

CMSEF will notify the Person subject to a Disciplinary Panel decision within thirty days of the action taken 

against such Person. 

Rule 518 Sanctions 

After notice and opportunity for hearing in accordance with these Rules, CMSEF will impose sanctions if 

any Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers, or 

other Person using any of the Participant’s User IDs is found to have violated or to have attempted to violate 

a Rule or provision of applicable law for which CMSEF possesses disciplinary jurisdiction. Any such 

sanctions shall take into account the respondent’s disciplinary history (if any). CMSEF may impose one or 

more of the following sanctions or remedies: 

(i) a warning letter, provided that no more than one warning letter may be issued to the same 

respondent found to have committed the same rule violation within a rolling 12-month period; 

(ii) censure; 

(iii) limitation, restriction or qualification of Trading Privileges or other activities, functions or 

operations; 

(iv) suspension of Trading Privileges for a period not to exceed 12 months; 

(v) fine (subject to this Rule); 

(vi) restitution or disgorgement (in the event of a Customer harm, full Customer restitution, except 

where the amount of restitution or to whom it should be provided cannot reasonably be 

determined); 

(vii) termination of Trading Privileges; 

(viii) expulsion; or 

(ix) any other sanction or remedy deemed to be appropriate. 

CMSEF will consider the severity of the violation and the deterrent effect when determining an appropriate 

sanction.

CMSEF may impose a fine of up to $100,000 for each violation. If a fine or other amount is not paid within 

30 days of the date that it becomes payable, then interest will accrue on the sum from the date that it became 

payable at the quoted prime rate plus three per cent. CMSEF has sole discretion to select the bank on whose 

quotations to base the prime rate. Each Participant will be responsible for paying any fine or other amount 

imposed on, but not paid by, any of its Authorized Persons or Authorized Users. 

Rule 519 Appeal from Disciplinary Panel Decision, Summary Impositions of Fines and Other Summary Actions 

Each respondent found by the Disciplinary Panel to have violated (or, in the case of a Participant, whose 

Authorized User, Clearing Member or other Person using its User ID was found to have violated) a Rule or 

who is subject to any summary fine imposed pursuant to these Rules or any summary action imposed pursuant 

to these Rules may appeal the decision within 20 days of receiving the order of the Disciplinary Panel or the 

notice of summary action, as the case may be, by filing a notice of appeal with the Chief Compliance Officer. 

The Compliance Department may appeal all or any part of a decision of the Disciplinary Panel, including 

any sanctions that may or may not have been imposed by the Disciplinary Panel, within 20 days of receiving 

the order of the Disciplinary Panel, by filing a notice of appeal with the Chief Compliance Officer.

While an appeal is pending, the effect of the order of the Disciplinary Panel or the summary action (including 

any sanctions, remedies or costs imposed thereby) shall be suspended. 
CMSEF Rulebook CMSEF Page 44

The notice of appeal must state in writing the grounds for appeal, including the findings of fact, conclusions 

or sanctions to which the respondent objects. An appellant may appeal the order of the Disciplinary Panel or 

any summary action on the grounds that: 

(i) the order or summary action was arbitrary, capricious, an abuse of discretion, or not in 

accordance with these Rules; 

(ii) the order or summary action exceeded the authority or jurisdiction of the Disciplinary Panel, 

the Chief Compliance Officer or CMSEF; 

(iii) the order or summary action failed to observe required procedures; 

(iv) the order or summary action was unsupported by the facts or evidence; or 

(v) the sanctions, remedies or costs, which were imposed, were inappropriate or unsupported by 

the record. 

The Chief Compliance Officer will forward copies of any notice of appeal received by it to all parties to the 

Disciplinary Proceeding or summary action, as the case may be, except the appellant. On or before the 20th 

day after filing a notice of appeal, the appellant must file with the Chief Compliance Officer and serve on the 

Compliance Department a brief supporting the notice of appeal and documents supporting the brief. On or 

before the 20th day after the date on which the appellant serves their supporting brief, the appellee must file 

and serve its brief in opposition. On or before the 10th day after the date on which the appellee serves its 

brief in opposition, the appellant must file and serve a brief in reply on the Compliance Department. 

In connection with any appeal, the Compliance Department will furnish to the Chief Compliance Officer and 

to the respondent/appellant a transcript of the hearing, any exhibits introduced at the hearing, the notice of 

appeal and briefs filed to support and oppose the appeal. 

No later than 30 days after the last submission filed pursuant to this Rule, the Chief Compliance Officer will 

appoint an Appeals Panel to consider and determine the appeal. An Appeals Panel shall be comprised of

three individuals, none of whom shall be a member of the Compliance Department or have been a member 

of any Disciplinary Panel involved in the matters on appeal. The chairman of the Appeals Panel shall be an 

individual who would not be disqualified from serving as a Public Director.

Within 10 days of being notified of the appointment of the Appeals Panel, a respondent may seek to disqualify 

any individual named to the Appeals Panel for the reasons identified in these Rules, by serving written notice 

on the Chief Compliance Officer. By not filing a timely request for disqualification, the respondent will be 

deemed to have waived any objection to the composition of the Appeals Panel. The Chief Compliance 

Officer will decide the merits of any request for disqualification within his or her sole discretion. Any such 

decision will be final and not subject to appeal. 

The Appeals Panel may hold a hearing to allow parties to present oral arguments. Any hearing will be 

conducted privately and confidentially. Notwithstanding the confidentiality of hearings, the Appeals Panel 

may appoint an expert to attend any hearing and assist in the deliberations if such individuals agree to be 

subject to appropriate confidentiality agreements. In determining procedural and evidentiary matters, the 

Appeals Panel will not be bound by evidentiary or procedural rules or law. 

The Appeals Panel will only consider on appeal the record before the Disciplinary Panel or, in the case of a 

summary action, the record considered by the Chief Compliance Officer, the notice of appeal, the briefs filed 

in support and opposition of the appeal, and any oral arguments of the parties. The Appeals Panel may only 

consider new evidence when the Appeals Panel is satisfied that good cause exists for why the evidence was 

not introduced during the Disciplinary Proceeding or when imposing the summary action. 

After completing its review, the Appeals Panel may affirm, modify or reverse any order of the Disciplinary 

Panel or summary action under appeal, in whole or in part, including increasing, decreasing or eliminating 

any sanction or remedy imposed, imposing any other sanction or remedy authorized by these Rules, or 

remanding the matter to the same or a different Disciplinary Panel for further Disciplinary Proceedings or 

for reconsideration by the Chief Compliance Officer in the case of summary action. The Appeals Panel may 

order a new hearing for good cause or if the Appeals Panel deems it appropriate. 
CMSEF Rulebook CMSEF Page 45

As promptly as reasonably possible following its review, the Appeals Panel will issue a written decision on 

appeal rendering its decision based on the weight of the evidence before the Appeals Panel. The decision of 

the Appeals Panel will include a statement of findings of fact and conclusions for each finding, sanction, 

remedy and cost reviewed on appeal, including each specific Rule and provision of applicable law that the 

respondent is found to have violated, if any, and the imposition of sanctions, remedies and costs, if any, and 

the effective date of each sanction, remedy or cost. 

The Appeals Panel’s written order on appeal (including findings of fact and conclusions and the imposition 

of sanctions, remedies and costs, and the effective date of any sanction, remedy cost) will be the final action 

of CMSEF and will not be subject to appeal within CMSEF.

Rule 520 Summary Imposition of Fines 

The Chief Compliance Officer may summarily impose a fine against a Participant (on behalf of itself or any 

of its Authorized Persons, Authorized Users, or Customers, or other Persons using any of its User IDs), 

Clearing Member, or Authorized User for failing: 

(i) to timely pay fees, cost, charges or fines to CMSEF or a DCO; 

(ii) to make timely and accurate submissions to CMSEF of notices, reports or other 

information required by these Rules; and 

(iii) to keep any books and records required by these Rules. 

The Compliance Department, acting on behalf of the Chief Compliance Officer, will give notice of any fine 

imposed pursuant to this Rule to each Participant or Authorized User subject thereto. The notice will specify:

(i) the violation of these Rules for which the fine is being imposed;

(ii) the date of the violation; and 

(iii) the amount of the fine. Within 20 days of serving the notice of fine, the Participant, or 

Authorized User, as the case may be, must either pay or cause the payment of the fine or 

file notice of an appeal pursuant to these Rules. Unless timely notice of appeal is filed 

pursuant to these Rules, the fine will become final upon the expiration of 20 days after the 

notice of fine is served on the Participant, or Authorized User, as the case may be. 

CMSEF will set the amount of any fines imposed pursuant to this Rule, with the maximum fine for each 

violation not to exceed $5,000. Summary imposition of fines pursuant to this Rule will not preclude CMSEF 

from bringing any other action against the Participant, or Authorized User, as the case may be. 

Rule 521 Summary Suspensions and Other Summary Actions 

Notwithstanding anything in these Rules to the contrary, if the Chief Compliance Officer reasonably believes 

that immediate action is necessary to protect the best interests of CMSEF or the marketplace, the Chief 

Compliance Officer may, after consultation with the Regulatory Oversight Committee summarily suspend, 

revoke, limit, condition, restrict or qualify the Trading Privileges of a Participant or Authorized User and 

take other summary action against a Participant or any of its Authorized Users in accordance with these 

Rules. 

Whenever practicable, the Compliance Department, acting on behalf of the Chief Compliance Officer, shall 

provide prior written notice to the party against whom any action in accordance with this Rule shall be taken. 

If prior notice is not practicable, CMSEF will give notice at the earliest possible opportunity to the respondent 

against whom the action is brought. The Compliance Department, acting on behalf of the Chief Compliance 

Officer, will prepare a notice of summary action (which will state the action, the reasons for the action, and 

the effective time, date and duration of the action) and serve the notice on such party and advise the recipient 

of the notice of its right to a prompt hearing before a Disciplinary Panel and its right to be represented by 

legal counsel or other representative at such hearing. A request by the recipient of the notice for such a 

hearing shall not delay the effectiveness of the summary action. 
CMSEF Rulebook CMSEF Page 46

At the request of CMSEF, a respondent against whom a summary action is brought pursuant to this Rule 

must provide books and records over which the respondent has access or control and must furnish information 

to, or appear or testify before, CMSEF or the Disciplinary Panel with the enforcement of any Rule. 

If a hearing is requested pursuant to this Rule, the Disciplinary Panel will promptly convene a hearing to be 

conducted in accordance with these Rules.

As promptly as reasonably possible after the hearing, the Disciplinary Panel will issue to the respondent a 

written order affirming, modifying, or reversing the summary action. The order will include a description of 

the summary action taken, a summary of the evidence introduced at the reinstatement hearing, a statement of 

findings of fact and conclusions, a description of any action taken or to be taken by CMSEF, and the effective 

date, time and duration thereof. 

Any decision of a Disciplinary Panel pursuant to this Rule will be the final action of CMSEF, and not subject 

to appeal within CMSEF upon serving the respondent with a copy of the decision. 

Rule 522 Reinstatement after Summary Suspension 

A respondent whose Trading Privileges are suspended, revoked, limited, conditioned, restricted or qualified 

pursuant to these Rules may apply for reinstatement by filing with the Compliance Department a written 

request stating the applicant’s reasons for seeking reinstatement. CMSEF will not consider a respondent’s 

request for reinstatement if the respondent 

(i) owes any fines, fees, charges or costs to CMSEF, 

(ii) continues to fail to appear at Disciplinary Proceedings without good cause or 

(iii) continues to impede the progress of Disciplinary Proceedings. 

Within a reasonable period after the filing of a request for reinstatement, the Appeals Panel will conduct a 

hearing to consider the request. At the hearing for reinstatement, the respondent will present its, his case 

supporting the reinstatement and the Compliance Department, acting on behalf of the Chief Compliance 

Officer may, in its discretion, present its case opposing or supporting the reinstatement and each may present 

relevant and admissible evidence and facts and call, examine and cross-examine witnesses. At the hearing 

for reinstatement, CMSEF may require Participants, Authorized Persons, Authorized Users, Clearing 

Members, or Participant’s Customers to appear as witnesses and produce evidence if the Appeals Panel 

determines that the evidence is relevant. 

As promptly as reasonably possible after a reinstatement hearing, the Appeals Panel will issue an order 

reinstating, denying the reinstatement, or placing conditions on the reinstatement of the Trading Privileges 

of the respondent. The order will include a brief summary of the evidence introduced at the reinstatement 

hearing; and, if applicable, findings of fact and conclusions not contained in the notice of summary action 

issued pursuant to these Rules. The order of the Appeals Panel may not be appealed. 

Rule 523 Rights and Responsibilities after Suspension or Termination 

When the Trading Privileges of a Participant or Authorized User are suspended for a period of 12 months or 

less, none of its rights and Trading Privileges (including the right to hold oneself out to the public as a 

Participant or Authorized User or enter Orders or RFQs into the SEF and receive Participant rates for fees, 

costs, and charges and deposit margin at Participant levels) will apply to such Participant, Authorized Person 

or Authorized User during the period of the suspension, except for the right to assert claims against others as 

provided in these Rules. Any such suspension will not affect the rights of creditors under these Rules or 

relieve the Participant or Authorized User of its obligations under these Rules to perform any Swaps entered 

into before the suspension, or for any Company fees, costs, or charges incurred during the suspension. 

CMSEF may discipline a suspended Participant, Authorized Person or Authorized User under this Chapter 5 

for any violation of a Rule or provision of applicable law committed by the Participant or Authorized User 

before, during or after the suspension.
CMSEF Rulebook CMSEF Page 47

When the Trading Privileges of a Participant or Authorized User are terminated, all of its rights and Trading 

Privileges will terminate, except for the right of the Participant, Authorized Person or Authorized User in 

question to assert claims against others, as provided in these Rules. Any such termination will not affect the 

rights of creditors under these Rules. A terminated Participant or Authorized User may only seek to reinstate 

his Trading Privileges by providing CMSEF with satisfactory evidence that he complies with these Rules. 

CMSEF will not consider the application of a terminated Participant or Authorized User if such Participant 

or Authorized User, as the case may be, fails to appear at Disciplinary Proceedings without good cause or 

impedes the progress of Disciplinary Proceedings. 

A suspended or terminated Participant or Authorized User remains subject to these Rules and the jurisdiction 

of CMSEF for any acts or omissions prior to the suspension or termination, and must cooperate in any 

Investigation, Disciplinary Proceeding, appeal from Disciplinary Proceedings, summary suspension or other 

summary action as if the suspended or terminated Participant or Authorized User still had Trading Privileges. 

Rule 524 Notice of Disciplinary Proceedings 

CMSEF will provide written notice of Disciplinary Proceedings to the parties and the RSP consistent with 

applicable CFTC Regulations. Whenever CMSEF suspends, expels, fines or otherwise disciplines, or denies 

any Person access, to CMSEF, CMSEF will make the public disclosures required by CFTC Regulations.

Rule 525 CFTC Review of CMSEF Actions

The review by the CFTC, pursuant to section 8c of the Act, as amended, of any suspension, expulsion, 

disciplinary or access denial action, or other adverse action by CMSEF, shall be governed by Part 9 of the 

CFTC’s Regulations.

separate signature from the Participant that CMSEF is collecting data or personal information for CMSEF’s

regulatory role. 

Rule 604 Publication of Trading Information

directly or indirectly, any Swap traded on CMSEF or any other SEF where such individual has access to

Rule 406 Execution of Swaps on CMSEF

The following are the acceptable methods CMSEF provides Participants in order to execute Swaps on 

CMSEF:

(i) Anonymous Central Limit Order Book (Minimum Functionality):

a. Acceptable Orders. The following kinds of orders may be entered into the Central Limit 

Order Book (CLOB) of the CMSEF Platform.

I. Limit Orders. A “Limit Order” is an order to buy or sell a contract at a specified 

price or better.

II. Market Orders. A “Market Order” is an order to purchase or sell a contract at the

best price on the CMSEF Platform at the time the order is entered on the CMSEF 

Platform (only available via fix API connection).

III. Fill or Kill. A “Fill or Kill” Order must be filled entirely or the Order is cancelled. 

IV. Immediate or Cancel. An “Immediate or Cancel” Order must be filled instantly 

or the Order is cancelled. 

b. Good until Time. An Order may be entered such that the Order is cancelled at a specific 

time if it is not executed (note that this feature is not available if accessing the system 

through the CMSEF website).

c. Entry of Orders. An anonymous order may be submitted directly by the Participant for its 

own account or on behalf of a Customer on whose behalf such a Participant is authorized 

to act. Each order on the CLOB must contain the following information:

I. Bid/Offer Indication

II. Price

III. Notional Amount 

IV. Instrument 

d. Time Delay Requirement. All Participants that are a broker or dealer and who, in 

connection with the execution of a Required Transaction, seek to either execute against a 

Customer’s order or execute two Customers against each other through the CMSEF’s 

CLOB shall use the following procedure:
CMSEF Rulebook CMSEF Page 27

I. If a Participant seeks to execute an order against a Customer order, then such 

Participant must enter the Customer order into the CMSEF CLOB and then wait 

at least 15 seconds before entering the Participant’s order; or

II. If a Participant seeks to execute two Customer orders against each other, then such 

Participant shall enter one side of the trade into the CMSEF CLOB and wait at 

least 15 seconds before entering the second side of the trade for execution.

e. Time Delay Exception. The time delay requirement does not apply to DMA Orders where 

a broker or dealer does not engage in some form of pre-arrangement or pre-negotiation of 

such order.

f. Price-Time Priority. All prices received in the CLOB are sorted based on strict price-time 

priority protocol.

g. Trading Limits. Participants shall only enter orders for such contracts and for such amounts 

as is permitted within the scope of their trading limits.

h. Matching of Orders. Orders submitted will be matched as follows:

I. Market Orders. Matching orders will be matched against all pending bids and 

offers in accordance with a price-time priority protocol. If any portion of the 

market order is not filled, the unfilled remainder will be canceled.

II. Limit Orders. Limit orders will be matched with bids and offers that have a price 

that is at or better than the price of the limit order, in accordance with the pricetime protocol. If any portion of the limit order is not filled, the unfilled portion of 

the order will remain in the market at the price and time that the order was entered. 

i. Unfilled Orders.

I. After the close of trading each Trading Day, all unfilled bids and offers will be 

cancelled

II. Upon a Participant’s logging out from the CMSEF Platform during the Trading 

Day, all unfilled bids and offers entered by such Participant will be cancelled.

j. Matching Algorithm. The CMSEF matching engine operates as a market order/limit order 

system. Orders are handled as follows:

I. Market orders are executed at the top of the market and can be matched with 

multiple standing orders at different prices if necessary to fill the market order 

volume;

II. Limit orders will execute at the requested price or better; and

III. Any unmatched limit order (or portion of an order) becomes a standing order in 

the system.

k. Counterparty Anonymity. 

I. Except as otherwise required under the Act or the Commission’s regulations, 

CMSEF shall not directly or indirectly, including through a third-party service 

provider, disclose the identity of a counterparty to a Swap that is executed 

anonymously and intended to be cleared.

II. It is prohibited for any Participant or Authorized User, directly or indirectly, 

including through a third-party service provider, to disclose the identity of a 

counterparty to a Swap that is executed anonymously and intended to be cleared.

III. For purposes of subsections I and II above, ‘‘executed anonymously’’ shall 

include a Swap that is pre-arranged or pre-negotiated anonymously, including by 

a Participant of CMSEF.

IV. For a package transaction that includes a component transaction that is not a Swap 

intended to be cleared, disclosing the identity of a counterparty shall not violate 

subsections I and II above. For purposes of this paragraph, a ‘‘package 

transaction’’ consists of two or more component transactions executed between 

two or more counterparties where:

1. Execution of each component transaction is contingent upon the 

execution of all other component transactions; and

2. The component transactions are priced or quoted together as one 

economic transaction with simultaneous or near-simultaneous execution 

of all components.
CMSEF Rulebook CMSEF Page 28

(ii) Request for Quote (RFQ)

a. Orders Entry. Participants may submit RFQ inquiries on a name disclosed basis. Unless 

the Participant is submitting an RFQ pursuant to Rule 416, submission of RFQ inquiries 

must be sent to minimum of three counterparties; none of which shall be: 

I. affiliated of or controlled by the counterparty requesting the RFQ inquiry; or 

II. affiliates of or controlled by each other.

b. Bids and Offers. At the same time that the requester receives the first responsive bid or 

offer, CMSEF shall communicate to the requester any firm bid or offer pertaining to the 

same instrument resting on the CLOB.

c. Responses. CMSEF shall provide the requester with the ability to execute against any firm 

CLOB bids or offers along with any responsive orders to the RFQ. 

d. Execution of Orders. The requester may accept any response to the RFQ upon receipt. 

After the requester accepts an RFQ, the responding party is given a “last look” in order to 

execute the Order. 

e. Trading Protocols. CMSEF will ensure that its trading protocols provide each Participant

with equal priority in receiving RFQs and in transmitting and displaying for execution 

responses to RFQs. 

f. Submitting a Request. Each RFQ shall include the following information regarding the 

Swap that the Participant is requesting quotes:

I. Product

II. Pay/Receive Indication

III. DCO

IV. Currency

V. Tenor

VI. Frequency

VII. Day Count

VIII. Instrument(s)

IX. Effective Date

X. End Date

XI. Business Day Conversion

XII. Calendar

XIII. Roll Conversion

XIV. Notional Amount

XV. Day Count Fraction

XVI. Clearing FCM 

g. Response to RFQ. Each response to an RFQ must contain a price.

h. Last Look. After the RFQ requester receives a quote, the requester will be able to execute. 

If the requester executes the quote, the Participant that submitted the quote will have a “last 

look” where such Participant will confirm the quote. The last look will expire in 30 seconds 

and until the Participant confirms the quote the requester may cancel the quote. 

Customer. The Customer requesting a quote on the RFQ system must be identified by the 

Participant entering the request, regardless if the Customer is the Participant or an 

Authorized User. 

(iii) Voice Order-Entry. A Participant may enter any order on the CLOB (Rule 406(i)) or RFQ 

(Rule 406(ii)) systems through communication with a Voice Agent. In this manner, any action 

that is permissible on the CLOB or RFQ may be taken on behalf of the Participant by the Voice 

Agent at the direction of the Participant.

(iv) Priorities of Orders: For any bid or offer on the CLOB, and for any RFQ or response to an 

RFQ, each Participant shall be given equal priority in terms of when such actions shall be 

displayed to the relevant Participants on CMSEF. Each order submitted on the SEF shall 

include the following:

a. The Legal Entity Identifier of the Participant or Client placing the order;

b. A yes/no indication of whether the Participant or Client is a swap dealer with respect to the 

product with respect to which the order is placed.
CMSEF Rulebook CMSEF Page 29

c. A yes/no indication of whether the Participant or Client is a major swap participant with 

respect to the product with respect to which the order is placed.

d. A yes/no indication of whether the Participant or Client is a Financial Entity.

e. A yes/no indication of whether the Participant or Client is a U.S. Person.

f. If applicable, an indication that the Participant or Client will elect the clearing requirement 

exception in CEA section (2)(h)(7) for any swap resulting from the order.

(v) Brokered Orders: Participants may enter an Order through a Registered Broker for which the 

Participant has entered into an agreement that permits the Registered Broker to act on behalf of 

the Participant. Such Order are treated as if the Order was entered directly by the Participant, 

under the rules of CMSEF.

Rule 407A Required Transactions

Required Transactions that do not qualify as a Block Trade or a Clearing Exception shall be executed on CMSEF 

according to Rule 406.

Rule 407B Permitted Transactions

Permitted Transactions shall be executed on CMSEF according to Rule 406, with the following qualifications:

(i) Permitted Transactions may be entered via RFQ to any number of Participants; and 

(ii) Permitted Transactions negotiated off-SEF may be entered for execution and clearing by the 

staff of the SEF directly, at the direction of a Registered Broker. 

Rule 407C Clearing Exception for Swaps 

Each Participant wishing to execute an Order under a Clearing Exception on CMSEF must submit all 

documentation required by Part 50 of the CFTC Regulations (the Clearing Exception Form) prior to placing 

an Order subject to the Clearing Exception. A Participant shall submit all required documentation supporting 

its eligibility (or the eligibility of its relevant Authorized User, as applicable) for the Clearing Exception. 

Any Order subject to the Clearing Exception shall be rejected if an applicable Clearing Exception Form is 

not on file with CMSEF. 

The Clearing Exception may only be used for Orders that are not executed on the CLOB. 

Rule 408 Cancellation of Orders by Participants

Participants may cancel any Order that has been entered on CMSEF, unless it has been executed or has 

expired. 

Rule 409 Modification or Cancellation of Orders and Trades by CMSEF

Before an Order is sent to a Clearinghouse, CMSEF may cancel any Order that, if allowed to remain, would 

have meaningful adverse effects on the integrity of the market, if the Order is entered in a price outside a 

range known as the Acceptable Price Range, or a CMSEF system malfunction. The Acceptable Price Range 

shall be determined by CMSEF based on the market data available to CMSEF. It may change from time to 

time and shall be published on the CMSEF website. 

Once a trade has been cleared by a Clearinghouse, CMSEF may adjust trade prices or cancel if there is a 

CMSEF system malfunction or with the consent of both Counterparties. Such modification or cancellation 

shall be effected by a pre-arranged trade or trades, consistent with CFTC No-Action Letter No. 15-24

(published by the CFTC on April 22, 2015; relief last extended May 30, 2017). 
CMSEF Rulebook CMSEF Page 30

At any time, CMSEF may halt or suspend trading on its platform in order to maintain a fair and orderly 

market, as required by these Rules. Any halt or suspension in trading shall be communicated to Participants 

as soon as practicable. 

If CMSEF takes action pursuant to this Rule, it will give prompt notice to affected Participant or Participants. 

Rule 410A Pre-Execution Credit Checks

CMSEF will verify prior to the execution of any Order that the Participants or Authorized User have sufficient 

credit limits with their Clearing Members so that the trade will be able to be accepted by the Clearing House 

for Clearing. CMSEF will not permit Participants or Authorized User to execute transactions if their credit 

limits are insufficient. 

All Orders will be prescreened on an order-by-order basis. A Clearing Member may reject an Order preexecution or post-execution. If an Order is rejected by the Clearing Member post-execution, such Order shall 

be void ab initio.

It is the responsibility of the Participants or Authorized User to evaluate the credit quality of their Prime 

Broker, FCM, and/or Clearinghouse, and their counterparty on uncleared swaps.

Rule 410B Confirmation of Agreements Between Counterparties

The terms of the Swap, which shall serve as a confirmation of the transaction, will be sent at the time of 

execution of the Swap. Specifically, upon the execution of a Swap, CMSEF will provide each counterparty 

to a transaction that is entered into on or pursuant to the rules of the SEF with a written record of all of the 

terms of the Swap, which shall legally supersede any previous agreement and serve as a confirmation of the 

transaction; provided, that specific Customer identifiers for accounts included in bunched orders involving 

Swaps will not be included in confirmations provided by CMSEF if the applicable requirements of CFTC 

Regulation 1.35(b)(5) are met. Confirmations of Swaps delivered to counterparties shall not include any 

information that violates Rule 406(i)(k).

Rule 411 Cleared Swaps

The following does not apply with respect to swaps subject to the clearing requirement exception in CEA 

section (2)(h)(7) for which a counterparty has elected such exception. 

Each Cleared Swap shall be cleared through the Clearing House indicated in the Swap Specification in 

accordance with the CEA and the CFTC Regulations.

For each Cleared Swap a Participant expects to enter into via the SEF Platform or subject to CMSEF Rules, 

the Participant or a Client or Customer of the Participant must establish a clearing account with the Clearing 

House or with a Clearing Member of the Clearing House, in each case, designated in the Swap Specification 

for such Cleared Swap.

Submission of executed trades to the applicable DCO shall be the responsibility of CMSEF. 

Rule 412 Position Limits and Accountability

To reduce the potential threat of market manipulation or congestion, SEF shall adopt for each of the contracts 

of the facility, as is deemed necessary and appropriate by SEF, position limitations or position accountability 

levels for speculators.

Rule 413A Position Limits
CMSEF Rulebook CMSEF Page 31

In accordance with CFTC Regulations, CMSEF may from time to time adopt position limits and grant 

exceptions from position limits as may be necessary.

CMSEF shall not set position limits in excess of CFTC limits.

CMSEF reserves the right to take any actions necessary in response to any Emergency situation that may 

arise including forcing any Participant to reduce any outstanding positions.

Rule 413B Position Accountability 

All Participants shall be bound by CMSEF’s position accountability levels for Required Transactions. 

CMSEF will set these levels in accordance with appropriate CFTC Regulations. 

In the event a Participant holds or controls aggregate positions in a Swap in excess of CMSEF position 

accountability levels, the Participant shall be subject to the following: 

(i) The Participant shall promptly provide any information requested by CMSEF concerning size 

and type of the position and any efforts to hedge the position.

(ii) The Participant shall, if directed by CMSEF, liquidate in an orderly manner, or not increase 

further the positions, which exceed CMSEF’s position accountability levels. 

(iii) The Participant shall, upon request by CMSEF, identify the beneficial owner and or any 

controlling parties for such positions.

CMSEF reserves the right to take any actions necessary in response to any Emergency situation that may 

arise, including forcing any Participant to reduce any outstanding positions.

Rule 414 Real-Time Market Monitoring and Surveillance

Real-time monitoring of trading on CMSEF for compliance purposes shall be conducted by CMSEF’s 

Compliance Department. CMSEF will monitor and surveil participants and market data on an ongoing and 

real time basis to ensure compliance with all applicable laws, rules, regulations and the CMSEF rulebook. If 

CMSEF believes a violation may be occurring or about to occur CMSEF may take actions including, but not 

limited to, halting a Participant's ability to execute trades on CMSEF.

in the failure of the market price to reflect the normal forces of supply and demand, unusual 

trading volumes, and impairments to market liquidity.

(ii) In addition, CMSEF may protect market integrity through use of the following safeguards to prevent 

the entry of orders in any of the following circumstances:

a. pre-trade quantity limits on individual orders to screen for order quantities not within 

acceptable parameters;

b. pre-trade price collars to screen for orders outside of current market conditions; and

c. pre-trade check to screen for risk based limits set by the clearing member.

Such pre trade quantity and risk limits shall be posted on CMSEF’s web site.

CMSEF shall not be held liable for any Customer Orders, which are mishandled by Participants. Participants 

will be solely responsible for all remedial actions in the event a Participant mishandles a Customer Order.

Rule 416A Block Trades 

CMSEF’s appropriate minimum block sizes shall be consistent with appropriate minimum block sizes set by 

the CFTC. CMSEF shall not permit Participants to execute Swaps as Block Trades below the appropriate 

minimum block size set by the CFTC. 

The following Block Trade Rules shall apply to Block Trades executed on CMSEF:

(i) Block Trades shall be trades that are at or in excess of the appropriate minimum block size set by 

the CFTC and may be executed on CMSEF by RFQ by requesting a price from fewer than three 

RFQ Receivers.

(ii) Block Trades must trade at prices that are fair and reasonable in the context of:

(ii) other transactions in the market at the time; and

(iii) the nature of the Participants to the Block Trade.

(iii) Block Trades shall not affect resting orders.

(iv) Participants shall not aggregate Orders for different accounts to create Block Trades unless 

permitted by CFTC Regulation 43.6(h)(6).

(v) Block Trades executed off CMSEF must be reported by the Participants to CMSEF as soon as

by an SDR. The actual notional or principal amount of the Block Trade shall be reported to CMSEF, 

which shall report the Block Trade as set forth in CFTC Regulation 43.6 and Appendices B, D, E, 

and F to Part 43 of the CFTC Regulations. 

CMSEF reserves the right to investigate all Block Trades to ensure that they comply with all applicable 

CMSEF Rules and CFTC Regulations.

A Participant transacting a Block Trade on behalf of a Customer must receive prior written instruction or 

consent from the Customer in order to do so. Such instruction or consent may be provided in the power of 

attorney or similar document by which the customer provides the person with discretionary trading authority 

or authority to direct the trading in its account.

The parties to a publicly reportable swap transaction on CMSEF that has a notional amount at or above the 

appropriate minimum block size shall notify CMSEF of its election to have the publicly reportable swap 

transaction treated as a Block Trade. CMSEF, pursuant to these Rules, shall notify the SDR of such a Block

Trade election when transmitting swap transaction and pricing data to such SDR in accordance with CFTC 

Regulation 43.3(b)(1).

Rule 416B Execution of Block Trades Through RFQ

Block Trades shall only be executed on CMSEF using the RFQ system, and only if the conditions of CFTC 

No-Action Letter No. 15-60 (published by the CFTC on November 2, 2015; relief expires November 15, 

2016) are met. These requirements are as follows:

(i) the Block Trade must meet the definition found in this Rulebook, and must be executed under 

the Rules of CMSEF;

(ii) a pre-trade credit check must be completed at the time the order for a block trade enters the 

Block Trade on the RFQ system; and

(iii) all Block Trades are subject to void ab initio requirements if swap is rejected on the basis of 

credit. 

Rule 417A Pre-Trade Communications

A Participant or Authorized User, acting on behalf of a Customer, must have the Customer’s consent before 

engaging in pre-arrangement communication with a counterparty. The Participant or Authorized User may 

not disclose such communications to any third party and may not use such communications to enter into 

alternative transactions other than the transaction permitted by this Rule. In any case in which a transaction 

is agreed upon as the result of pre-arrangement communication, the Participant or Participants must allow a 

15-second delay between orders entered on the SEF. There is no mechanism on the CMSEF system that 

prevents a trade from being submitted before such 15-second delay has occurred and therefore any applicable 

Order that is executed without the delay shall be a violation of these Rules and CFTC Regulations. 

Rule 417B Information Obtained in Pre-Trade Communications

All Participants or Authorized Users party to the pre-arrangement communication permitted by Rule 417A 

are prohibited from disclosing such communications to any third party and may not use such communications 

to enter into alternative transactions other than the transaction permitted by this rule.

Rule 418A Dissemination of Prices and Trading Information

CMSEF shall publish information daily on its website regarding prices, volume, and other data as required 

by the CFTC Regulations.

and offers.

CMSEF may make available to Participants an indicative, non-attributed pricing page on CMSEF for certain 

types of Swaps of the most commonly traded tenors within such type of Swap.

CMSEF shall choose, at its sole discretion, an SDR. As required by CFTC Regulation 37.901(a), CMSEF 

shall transmit swap transaction and pricing data for each Swap executed pursuant to these Rules to the 

appropriate SDR in the form and manner required. At this time, all trades on CMSEF will be reported to 

DTCC Data Repository (U.S.) LLC.

CMSEF may provide such swap transaction and pricing data to Participants and Authorized Users no earlier 

than the time it transmits such information to an SDR and in a form that does not disclose the identities, or 

otherwise facilitate identification, of the parties to the Swap.

Rule 418B Publicly Reportable Swap Transactions 
CMSEF Rulebook CMSEF Page 34

Pursuant to Part 43 and Appendix A to Part 43 of the CFTC Regulations and Part 45 and Appendix 1 to Part 

45 of the CFTC Regulations, CMSEF shall transmit swap transaction and pricing data and minimum primary 

economic terms to a registered SDR as soon as technologically practicable after the publicly reportable swap 

transaction has been executed on or pursuant to the rules of CMSEF.

CMSEF and Participants shall not submit or agree to submit a cancellation or correction for the purpose 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 in Part 43 of the 

CFTC Regulations. 

Rule 418C Reporting Counterparties 

For all swaps executed on CMSEF, each swap counterparty shall provide sufficient information to CMSEF 

to enable CMSEF to report all Required Swap Creation Data to enable CMSEF to report all Required Swap 

Creation Data. To achieve this, each Participant placing an order with respect to any Swap traded on CMSEF 

must include in the order the information required by CMSEF Rule 406(iii).

counterparties are swap dealers, (b) both counterparties are major swap participants, (c) both counterparties 

are a financial entities as defined by Section 2(h)(7)(C) of the CEA but not a swap dealer or a major swap 

participant, or (d) both counterparties are neither a swap dealer nor a major swap participants nor a financial 

entity as defined by Section 2(h)(7)(C) of the CEA, then the reporting counterparty shall be the buyer. 

All Reporting Counterparties are required to notify CMSEF in the event the Reporting Counterparty becomes 

aware that an error or omission in reporting has occurred. 

Rule 419 Emergency Rules

In the event of an Emergency, CMSEF may implement temporary Emergency procedures and Emergency 

Rules, subject to the applicable provisions of the CEA and CFTC Regulations. Implementation of Emergency 

Rules shall be done in consultation with the CFTC. Emergency Rules may require or authorize CMSEF, the

(xiii) imposing, modifying or reducing position limits.

Before any Emergency Rule may be adopted and enforced, a required vote of the Board must approve the 

implementation of such Emergency Rule at a duly convened meeting requested by the President or any other 

Officer. Directors may attend such a meeting by teleconference. Each Director participating in such meeting 

shall be subject to CMSEF’s Conflict of Interest Rules. If the CEO or CMSEF determines that Emergency 

Rules must be implemented with respect to an Emergency before a meeting of the Board can reasonably be 
CMSEF Rulebook CMSEF Page 35

convened, then the CEO shall have the authority, without Board action, to implement any Emergency Rules 

with respect to such Emergency that he or she deems necessary or appropriate to respond to such Emergency. 

Whenever CMSEF, the Board, any committee of the Board, or the President takes actions necessary or 

appropriate to respond to an Emergency (including the actions set forth above), an Authorized Representative 

of CMSEF will post a Notice to Participants regarding such Emergency, as soon as practicable. When the 

Board, any committee of the Board or the CEO determines that the Emergency is no longer in effect, 

permitting the SEF operated by CMSEF to resume normal functioning; any such actions responding to an 

Emergency will be terminated. 

CMSEF will use reasonable efforts to notify the CFTC prior to implementing, modifying or terminating an 

Emergency Rule. If such prior notification is not possible or practicable, CMSEF will notify the CFTC as 

soon as possible or reasonably practicable, but in all circumstances within twenty-four (24) hours of the 

implementation, modification or termination of such Emergency Rule. 

Upon taking any action in response to an Emergency, CMSEF will document the decision-making process 

related to such action. Such documentation will be kept for at least five years following the date on which 

the Emergency ceases to exist or to affect the SEF operated by CMSEF, and all such documentation will be 

provided to the CFTC upon request. 

Chapter 5 Disciplinary Rules

Rule 501 General 

All Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers 

shall be subject to the CMSEF’s jurisdiction. Participants, Authorized Persons, Authorized Users, Clearing 

Members, and Participant’s Customers are subject to this Chapter 5 if they, or with respect to a Participant, 

any other Person using any of its User IDs, are alleged to have violated, or to have aided and abetted a 

violation of, or are about to violate, any Rule or any provision of applicable law for which CMSEF possesses 

disciplinary jurisdiction. 

CMSEF, through its Compliance Department and the Disciplinary Panel, will conduct Investigations, 

Disciplinary Proceedings and appeals from Disciplinary Proceedings, summary impositions of fines,

CMSEF shall permit Participants, Authorized Persons, Authorized Users, Clearing Members, or Participant’s 

Customers to be represented by counsel during any Investigation, disciplinary hearing, or imposition of a 

fine or summary judgment.

CMSEF may hold a Participant or Authorized User liable for, and impose sanctions against such Participant 

or Authorized User for such Person’s own acts and omissions, or those of its agents, representatives or any 

Person or API using a User ID of such Participant or Authorized User. CMSEF may additionally hold a 

Participant liable for the acts and omissions of its Authorized Users. 

CMSEF may delegate any or all of its powers or responsibilities under this Chapter 5 to the RSP, which may 

take any action on behalf CMSEF that the CMSEF is permitted to take hereunder; provided, however, that 

the CMSEF shall retain supervisory authority with respect to such powers and responsibilities and will 

document instances where its actions differ in any material respect from those recommended by the RSP. 

Rule 502 CMSEF’s Right to Inspect Books, Records and Systems
CMSEF Rulebook CMSEF Page 36

CMSEF’s Compliance Department and CMSEF’s RSP (if any) will have the right to inspect the books, 

records, systems, equipment, and software of Participants, Authorized Persons, Authorized Users, Clearing 

Members and Participant’s Customers.

CMSEF’s Compliance Department and CMSEF’s RSP (if any) will have the right to obtain position and 

trading information directly from Participants as necessary to perform CMSEF’s Oversight functions as set 

forth in this Rulebook. 

Rule 503 Investigations

CMSEF’s Compliance Department or Disciplinary Panels will investigate any matter within CMSEF’s 

disciplinary jurisdiction of which it becomes aware. The Compliance Department will determine the nature 

and scope of its Investigations within its sole discretion and will function independently of any commercial 

interests of CMSEF. An Investigation will be initiated if the Compliance Department or other CMSEF 

Departments determines that a violation of CMSEF may have occurred. The Compliance Department may 

informally contact Participants in order to obtain information. 

Notwithstanding the above, CMSEF will commence an Investigation at the request of the CFTC. 

CMSEF’s Compliance Department has the authority to: 

(i) initiate and conduct Investigations; 

(ii) prepare Investigation Reports and make recommendations concerning initiating Disciplinary 

Proceedings; 

(iii) allege violations within CMSEF’s disciplinary jurisdiction; 

(iv) prosecute alleged violations within CMSEF’s disciplinary jurisdiction; and

(v) represent CMSEF on an appeal to an Appeal Panel of any Disciplinary Proceeding, summary 

imposition of fines, summary suspension or other summary action. 

Each Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers: 

(i) is obligated to appear, testify and respond in writing to interrogatories within the time 

period required by the Compliance Department in connection with any Rule, any 

Investigation; or any preparation by and presentation during a Disciplinary Proceeding or 

appeal from a decision in a Disciplinary Proceeding, summary imposition of fines, 

summary suspension or other summary action by CMSEF; 

(ii) is obligated to produce books, records, papers, documents or other tangible evidence in his 

possession, custody or control within the time period required by the Compliance 

Department in connection with any Rule, any Investigation, any preparation by and 

presentation during a Disciplinary Proceeding or appeal from a decision in any Disciplinary 

Proceeding, summary imposition of fines, summary suspension or other summary action 

by CMSEF; and 

(iii) may not impede or delay any Investigation, Disciplinary Proceeding, appeal from a 

Disciplinary Proceeding, summary imposition of fines, summary suspension or other 

summary action. 

Rule 504 Reports of Investigations 

CMSEF’s Compliance Department will maintain a log of all Investigations and their disposition. The 

Compliance Department will prepare a written report of each Investigation (the “Investigation Report”), 

regardless of whether the evidence gathered during any Investigation forms a reasonable basis to believe that 

a violation within CMSEF’s jurisdiction has occurred or is about to occur or whether the evidence gathered 

results in closing the matter without further action or through summary action. 

Any Investigation Report will include the reasons for initiating the Investigation (including a summary of the 

complaint, if any), all relevant facts and evidence gathered and the analysis, conclusions and recommendation 

of the Compliance Department. For each potential respondent, the Compliance Department will recommend 

either: 
CMSEF Rulebook CMSEF Page 37

(i) closing the Investigation without further action; 

(ii) entering into a summary action;

(iii) resolving the Investigation through an informal disposition, including the issuance by the 

Compliance Department of a warning letter (provided that no more than one warning letter for 

the same violation may be issued to the same potential respondent during a rolling 12-month 

period);

(iv) initiating Disciplinary Proceedings; or 

(v) negotiating a settlement. 

An informal disposition (including the issuance of a warning letter by the Compliance Department) will not 

constitute a finding of a violation or a sanction. 

CMSEF’s Compliance Department shall provide the Investigation Report to the Chief Compliance Officer, 

who shall determine whether the Investigation Report is complete.

CMSEF’s Compliance Department shall complete each Investigation in a timely manner and, absent 

mitigating factors, no later than 12 months after the date that such Investigation was opened. 

Rule 505 Opportunity to Respond to Investigation Reports 

After completing the Investigation Report, if the evidence gathered during an Investigation forms a 

reasonable basis to believe that a violation within CMSEF’s jurisdiction has occurred or is about to occur,

CMSEF’s Compliance Department may, upon approval of the Chief Compliance Officer, notify each 

potential respondent that the Compliance Department has recommended formal disciplinary charges against 

each such potential respondent. 

The potential respondents shall be notified in writing and shall have fourteen days to respond, unless 

extenuating circumstances require a response sooner.

CMSEF’s Compliance Department may allow a potential respondent to propose a settlement of the matter or 

to submit a written statement explaining why either a Disciplinary Proceeding should not be instituted or one 

or more of the potential charges should not be brought. The potential respondent shall submit such written 

statement within the time limit established by the Compliance Department. 

Rule 506 Review of Investigation Reports 

CMSEF’s Compliance Department will, within 30 days, take one of the following actions: 

(i) If CMSEF’s Compliance Department determines that no reasonable basis exists to believe that a 

violation within CMSEF’s jurisdiction has occurred or is about to occur, it may direct that no 

further action be taken. Upon such determination, the Compliance Department will provide a 

written statement setting forth the facts and analysis supporting the decision. 

(ii) If CMSEF’s Compliance Department determines that Disciplinary Proceedings are unwarranted, it 

may issue a warning letter setting forth, in writing, the facts and analysis supporting the decision. 

(iii) If CMSEF’s Compliance Department determines that additional inquiries or evidence is needed to 

decide whether a reasonable basis exists to believe that a violation within CMSEF’s jurisdiction 

has occurred or is about to occur, it will continue the Investigation. 

(iv) If CMSEF’s Compliance Department determines that a reasonable basis exists to believe that a 

violation within CMSEF’s jurisdiction has occurred or is about to occur, the potential respondent 

will be served with a notice of charges and proceed in accordance with this Chapter 5. 

Rule 507 Warnings
CMSEF Rulebook CMSEF Page 38

CMSEF’s Compliance Department is authorized to issue a warning letter to an individual or entity subject 

to an Investigation. If a warning letter is issued by the CMSEF’s Compliance Department, it shall not be 

considered an indication that a violation has occurred. Only one warning letter may be issued to the same 

individual or entity per violation per year.

Rule 508 Notice of Charges 

If CMSEF’s Compliance Department authorizes Disciplinary Proceedings pursuant to these Rules, it will 

prepare, and serve in accordance with these Rules, a notice of charges. 

A notice of charges will: 

(i) state the acts, practices or conduct in which the respondent is alleged to have engaged; 

(ii) state the Rule alleged to have been violated or about to be violated; 

(iii) advise the respondent of its right to a hearing and its right to be represented by legal counsel 

or any other representative of its choosing (other than a Director, Officer or Employee of 

CMSEF, any member of the Disciplinary Panel or any Person substantially related to the 

Disciplinary Proceedings such as a material witness or other respondent) in all succeeding 

stages of the disciplinary process; 

(iv) state the period of time within which the respondent can request a hearing on the notice of 

charges, which will not be less than 20 days after service of the notice of charges; 

(v) advise the respondent that any failure to request a hearing within the period stated, except 

for good cause, will be deemed to constitute a waiver of the right to a hearing; and 

(vi) advise the respondent that any allegation in the notice of charges that is not expressly 

denied will be deemed to be admitted. 

Rule 509 Service of Notice of Charges 

CMSEF shall serve notice of charges or other documents contemplated to be served pursuant to this Chapter 

5 to a contact designated by each Participant. CMSEF may serve such notice (and service shall be deemed 

complete) to the respondent personally, or by deposit in the United States mail, postage prepaid, via registered 

or certified mail addressed to the respondent at the address as it appears in records of CMSEF. Notice of 

Charges may also be served by electronic mail to the respondent’s electronic mail address as it appears on 

the books and records of CMSEF, if followed by a hard copy of the document sent promptly thereafter by 

registered or certified mail addressed to the respondent at the respondent’s address as it appears in records of 

CMSEF. 

Rule 510 Answer to Notice of Charges 

If the respondent determines to answer a notice of charges, the respondent must file an answer within 20 days 

after being served with such notice, or within such other time period determined appropriate by the Chief 

Compliance Officer. 

To answer a notice of charges, the respondent must in writing: 

(i) for each allegation set forth in the notice of charges, admit such allegation, deny such 

allegation, or affirmatively state that the respondent does not have and is unable to obtain 

sufficient information to admit or deny such allegation, which shall have the effect of a 

denial of such allegation; 

(ii) specify any specific facts that contradict the notice of charges; 

(iv) specify any affirmative defenses to the notice of charges; 

(iv) sign and serve the answer on the Chief Compliance Officer; and 

(v) if applicable, request a hearing before a Disciplinary Panel. 

Any failure by the respondent to serve a timely answer to a notice of charges will be deemed to be an 

admission to the allegations in such notice. Any failure by the respondent to answer one or more allegations 

in a notice of charges will be deemed to be an admission of that allegation or those allegations. Any allegation 
CMSEF Rulebook CMSEF Page 39

in a notice of charges that the respondent fails to deny will be deemed to be admitted. A general denial by 

the respondent, without more, will not satisfy the requirements of the second paragraph of this Rule. 

If a respondent admits or fails to specifically deny any of the allegations in the notice of charges, the 

Disciplinary Panel shall find that the violations set forth in such allegations have been committed and shall 

impose a sanction for such violations. The Disciplinary Panel shall promptly notify the respondent in writing 

of any sanction imposed pursuant to this Rule and advise the respondent that the respondent may request a 

hearing on such sanction within 20 days of the respondent being served with such notice. Any failure by the 

respondent to do so will be deemed to be an acceptance of the sanctions in such notice and waiver of any 

right to appeal such sanctions. 

A respondent shall be granted a hearing before a Disciplinary Panel for every instance in which such 

respondent either denies an allegation and requests a hearing in accordance with this Rule; or requests a 

hearing in accordance with this Rule.

Rule 511 Right to a Hearing

All respondents who have denied a charge shall be afforded the opportunity for a hearing. The hearing 

must concern only those charges, which the respondent has denied.

Rule 512 Settlements 

A respondent or potential respondent may at any time propose in writing an offer of settlement to anticipated 

or instituted Disciplinary Proceedings. Any offer of settlement should contain proposed findings and 

sanctions and be signed by the respondent or potential respondent and submitted to the Compliance 

Department, and shall take into account, among other things, the disciplinary history of the respondent or 

potential respondent. A respondent or potential respondent may offer to settle Disciplinary Proceedings 

without admitting or denying the findings contained in the order of the Disciplinary Proceedings but must 

accept the jurisdiction of CMSEF over it and over the subject matter of the proceedings and consent to the 

entry of the findings and sanctions imposed. 

If a respondent or potential respondent submits an offer of settlement in accordance with paragraph (a) of 

this Rule, the Compliance Department will forward the offer to the Disciplinary Panel with a recommendation 

on whether to accept or reject the offer. The respondent or potential respondent may withdraw such offer of 

settlement at any time before acceptance by the Disciplinary Panel, but may not withdraw such offer at any 

time after acceptance by the Disciplinary Panel. 

The Disciplinary Panel may accept the offer of settlement, but may not alter the terms of a settlement offer 

unless the respondent or potential respondent agrees. 

If an offer of settlement is accepted by the Disciplinary Panel, it shall issue a written decision specifying: 

(i) the Rule violations it has reason to believe were committed, including the basis or reasons 

for its conclusions; 

(ii) any sanction to be imposed, which must include full Customer restitution where Customer

harm has been demonstrated; and 

(iii) if applicable, that the respondent has accepted the sanctions imposed without either 

admitting or denying the Rule violations. 

In the event that the Disciplinary Panel accepts an offer of settlement without the agreement of the 

Compliance Department, the decision must adequately support such acceptance. 

If an offer of settlement is accepted and the related order of Disciplinary Proceedings becomes final, the 

respondent’s submission of the offer will be deemed to constitute a waiver of the right to notice, opportunity 

for a hearing and review and appeal under these Rules. 
CMSEF Rulebook CMSEF Page 40

If the offer of settlement of a respondent or potential respondent is not accepted by the Disciplinary Panel, 

fails to become final or is withdrawn by the respondent or potential respondent before its acceptance by the 

Disciplinary Panel, the matter will proceed as if the offer had not been made and the offer and all documents 

relating to it will not become part of the record. Neither a respondent or potential respondent nor the 

Compliance Department may use an unaccepted offer of settlement as an admission or in any other manner 

at a hearing of, or appeal from, Disciplinary Proceedings. 

Rule 513 Disciplinary Panels 

The Disciplinary Panel shall conduct hearings in connection with any Disciplinary Proceedings (except for 

summary impositions of fines pursuant to these Rules), to make findings, render decisions, and impose 

sanctions pursuant to this Chapter 5. 

Each Disciplinary Panel shall be composed of three individuals selected by the Chief Compliance Officer. 

Except in cases limited to the timely submission of accurate records, each Disciplinary Panel shall consist of 

an individual who would not be disqualified from serving as a Public Director, who shall chair the 

Disciplinary Panel. 

No member of the Compliance Department may serve on a Disciplinary Panel. 

Except as may otherwise be provided in these Rules, the Board may at any time remove any member of a 

Disciplinary Panel for cause. 

Within 10 days of being notified of the appointment of the Disciplinary Panel, a respondent may seek to 

disqualify any individual named to the Disciplinary Panel for the reasons identified in these Rules, by serving 

written notice on the Chief Compliance Officer and providing a copy thereof to the chairman of the 

Disciplinary Panel. By not timely filing a request for disqualification, the respondent will be deemed to have 

waived any objection to the composition of a Disciplinary Panel. The Chief Compliance Officer will decide 

in his sole discretion the merits of any request for disqualification. Any such decision will be final and not 

subject to appeal. 

All information, records, materials and documents provided to the Disciplinary Panel and all deliberations, 

testimony, information, records, materials and documents related thereto shall be treated as non-public and 

confidential and shall not be disclosed, except as necessary to further an Investigation or as otherwise required 

by law. No individual shall serve on a Disciplinary Panel unless that individual has agreed in writing that he 

will not publish, divulge, or make known in any manner facts or information regarding the business of any 

Person or other information which may come to his or her attention in his official capacity as a member of 

the Disciplinary Panel, except:

a. when reporting to the Board or to a Standing Committee concerned with such 

information;

b. when reporting to the Compliance Department;

c. when requested by the CFTC or other government agency; or 

d. when compelled to testify in any judicial or administrative proceeding. 

Rule 514 Convening Hearings of Disciplinary Proceedings 

All Disciplinary Proceedings (except for summary impositions of fines pursuant to these Rules) will be 

conducted at a hearing before a Disciplinary Panel. Hearings will be conducted fairly, privately and 

confidentially. Notwithstanding the confidentiality of hearings, the Disciplinary Panel may appoint an expert 

to attend any hearing and assist in deliberations if such expert agrees to be subject to an appropriate 

confidentiality agreement. 

After reasonable notice to each respondent, the Disciplinary Panel will promptly convene a hearing to 

conduct the Disciplinary Proceedings with respect to such respondent. Parties to a Disciplinary Proceeding

include each respondent and the Compliance Department. 
CMSEF Rulebook CMSEF Page 41

The chairman of the Disciplinary Panel may continue, adjourn or otherwise conduct the hearing, as he may 

deem appropriate. The chairman of the Disciplinary Panel will determine all procedural and evidentiary 

matters, including the admissibility and relevance of any evidence proffered. In determining procedural and 

evidentiary matters, the chairman of the Disciplinary Panel will not be bound by any evidentiary or procedural 

rules of law. Once admitted during the hearing, the Disciplinary Panel may consider, and attach the weight 

it believes appropriate to, evidence or other materials. CMSEF’s Legal Department will provide guidance to 

the chairman of the Disciplinary Panel on the conduct of the hearing. 

Except for procedural and evidentiary matters decided by the chairman of the Disciplinary Panel pursuant to 

these Rules, unless each respondent otherwise consents, the entire Disciplinary Panel must be present during 

the entire hearing and any related deliberations. 

Rule 515 Respondent Review of Evidence 

Prior to the commencement of a hearing, each respondent will be given the opportunity, subject to the sections 

below, to review all books, records, documents, papers, transcripts of testimony and other tangible evidence 

in the possession or under the control of CMSEF that the Compliance Department will use to support the 

allegations and proposed sanctions in the notice of charges or which the chairman of the Disciplinary Panel 

deems relevant to the Disciplinary Proceedings. Notwithstanding the foregoing, no respondent will have the 

right to review, and CMSEF will have no obligation to disclose, any information protected by attorney-client 

privilege. All requests for such information must be made not less than 10 days prior to the scheduled hearing 

date, unless the chairman of the Disciplinary Panel agrees otherwise. 

If any books, records, documents, papers, transcripts of testimony, or other tangible evidence contain 

information that could adversely affect the competitive position of the Person providing the information or 

if such information might compromise other Investigations being conducted by the Compliance Department, 

the Compliance Department may redact, edit or code such information before furnishing it to the respondent. 

Notwithstanding anything in this Rule to the contrary, the Compliance Department: 

(i) will not redact, edit or code competitive or investigative information contained in 

documents in a manner that would materially impair the respondent’s ability to defend 

against the allegations or proposed sanctions in the notices of charges, and 

(ii) will provide the respondent with access to the information and portions of the documents 

that the Compliance Department intends to rely on to support the allegations or proposed 

sanctions in the notice of charges. 

For purposes of these Rules, information that could adversely affect competitive positions includes positions 

in Swaps currently held, trading strategies employed in establishing or liquidating positions, the identity of 

any Participant or Authorized User and the personal finances of the Person providing the information. 

The respondent shall treat as confidential all data and information provided to it pursuant to these Rules, and 

shall not disclose any such data or information, except as necessary to the respondent’s defense of notice of 

charges and any appeal of the decision of the Disciplinary Panel.

Rule 516 Conducting Hearings of Disciplinary Proceedings 

At a hearing conducted in connection with any Disciplinary Proceedings, the Compliance Department will 

present its case supporting the allegations and proposed sanctions in the notice of charges to the Disciplinary 

Panel. If a respondent has timely filed an answer to the notice of charges in accordance with these Rules, the 

respondent is entitled to attend and participate in the hearing. 

At a hearing conducted in connection with any Disciplinary Proceedings, the Compliance Department and 

each respondent may: 

(i) present evidence and facts determined relevant and admissible by the chairman of the 

Disciplinary Panel; 

(ii) call and examine witnesses; and 
CMSEF Rulebook CMSEF Page 42

(iii) cross-examine witnesses called by other parties. 

If the respondent fails to file an answer, has filed a general denial, or if any or all of the allegations in the 

notice of charges are not expressly denied in the respondent’s answer, the chairman of the Disciplinary Panel 

may limit evidence concerning any allegations not expressly denied in determining the sanctions to impose. 

If a respondent fails to file an answer but appears at the hearing, the respondent may not participate in the 

hearing (by calling or cross-examining witnesses, testifying in defense, presenting evidence concerning the 

notice of charges, or otherwise) unless the Disciplinary Panel determines that the respondent had a 

compelling reason for failing to file a timely answer. If the Disciplinary Panel determines that the respondent 

had a compelling reason for failing to file a timely answer, the Disciplinary Panel will adjourn the hearing 

and direct the respondent to promptly file the written answer in accordance with these Rules. 

Any Person entitled, or required or called upon, to attend a hearing before a Disciplinary Panel pursuant to 

this Rule will be given reasonable notice, confirmed in writing, specifying the date, time and place of the 

hearing, and the caption of the Disciplinary Proceedings. CMSEF will require all Authorized Persons and 

Authorized Users that are called as witnesses to appear at the hearing and produce evidence. CMSEF will 

make reasonable efforts to secure the presence of all other Persons called as witnesses whose testimony would 

be relevant. 

If during any Disciplinary Proceedings the Disciplinary Panel determines that a reasonable basis exists to 

believe that the respondent violated a Rule or a provision of applicable law other than the violations alleged 

in the notice of charges, the Disciplinary Panel may consider those apparent violations after providing the 

respondent with an opportunity to answer the additional allegations in accordance with these Rules. In 

connection with considering apparent violations pursuant to this Rule, the Disciplinary Panel may request 

that the Compliance Department provide the Disciplinary Panel with any additional information. 

The Disciplinary Panel may summarily impose sanctions on any Participant, Authorized Person, or 

Authorized User that impedes or delays the progress of a hearing. 

CMSEF will arrange for any hearing conducted in connection with Disciplinary Proceedings to be recorded 

hearing verbatim, or substantially verbatim, in a manner capable of accurate transcription. The record shall 

not be transcribed unless requested by CTFC staff or the respondent or the decision is appealed. If the 

respondent requests a copy of all or portions of the recording of a hearing, the chairman of the Disciplinary 

Panel may within his sole discretion order the respondent to pay the costs for transcribing the recording of 

the hearing. 

No interlocutory appeals of rulings of any Disciplinary Panel or chairman of the Disciplinary Panel are 

permitted. 

Rule 517 Decision of Disciplinary Panel 

As promptly as reasonable following a hearing, the Disciplinary Panel will issue an order rendering its 

decision based on the weight of the evidence contained in the record of the Disciplinary Proceedings. A 

decision by a majority of the Disciplinary Panel will constitute the decision of the Disciplinary Panel. 

CMSEF will serve a copy of the order of the Disciplinary Panel on the respondent and the Compliance 

Department. The order will include: 

(i) the notice of charges or summary of the allegations; 

(ii) the answer, if any, or a summary of the answer; 

(iii) a brief summary of the evidence introduced at the hearing (or, where appropriate, incorporation 

by reference of the Investigation Report); 

(iv) findings of fact and conclusions concerning each allegation, including each specific Rule that 

the respondent is found to have violated; 

(v) the imposition of sanctions, if any, the basis for the sanctions, and effective date of each 

sanction; and 

(vi) notice of the respondent’s right to appeal pursuant to these Rules. 
CMSEF Rulebook CMSEF Page 43

A Disciplinary Panel shall be dissolved automatically when it has decided the matter for which it was 

appointed and has notified the respondent and the Chief Compliance Officer in writing of its decision. 

Unless a timely notice of appeal is filed pursuant to these Rules, the order of the Disciplinary Panel will 

become final upon the expiration of 20 days after the order is served on the respondent and a copy thereof is 

provided to the Compliance Department. 

CMSEF will notify the Person subject to a Disciplinary Panel decision within thirty days of the action taken 

against such Person. 

Rule 518 Sanctions 

After notice and opportunity for hearing in accordance with these Rules, CMSEF will impose sanctions if 

any Participants, Authorized Persons, Authorized Users, Clearing Members, and Participant’s Customers, or 

other Person using any of the Participant’s User IDs is found to have violated or to have attempted to violate 

a Rule or provision of applicable law for which CMSEF possesses disciplinary jurisdiction. Any such 

sanctions shall take into account the respondent’s disciplinary history (if any). CMSEF may impose one or 

more of the following sanctions or remedies: 

(i) a warning letter, provided that no more than one warning letter may be issued to the same 

respondent found to have committed the same rule violation within a rolling 12-month period; 

(ii) censure; 

(iii) limitation, restriction or qualification of Trading Privileges or other activities, functions or 

operations; 

(iv) suspension of Trading Privileges for a period not to exceed 12 months; 

(v) fine (subject to this Rule); 

(vi) restitution or disgorgement (in the event of a Customer harm, full Customer restitution, except 

where the amount of restitution or to whom it should be provided cannot reasonably be 

determined); 

(vii) termination of Trading Privileges; 

(viii) expulsion; or 

(ix) any other sanction or remedy deemed to be appropriate. 

CMSEF will consider the severity of the violation and the deterrent effect when determining an appropriate 

sanction.

CMSEF may impose a fine of up to $100,000 for each violation. If a fine or other amount is not paid within 

30 days of the date that it becomes payable, then interest will accrue on the sum from the date that it became 

payable at the quoted prime rate plus three per cent. CMSEF has sole discretion to select the bank on whose 

quotations to base the prime rate. Each Participant will be responsible for paying any fine or other amount 

imposed on, but not paid by, any of its Authorized Persons or Authorized Users. 

Rule 519 Appeal from Disciplinary Panel Decision, Summary Impositions of Fines and Other Summary Actions 

Each respondent found by the Disciplinary Panel to have violated (or, in the case of a Participant, whose 

Authorized User, Clearing Member or other Person using its User ID was found to have violated) a Rule or 

who is subject to any summary fine imposed pursuant to these Rules or any summary action imposed pursuant 

to these Rules may appeal the decision within 20 days of receiving the order of the Disciplinary Panel or the 

notice of summary action, as the case may be, by filing a notice of appeal with the Chief Compliance Officer. 

The Compliance Department may appeal all or any part of a decision of the Disciplinary Panel, including 

any sanctions that may or may not have been imposed by the Disciplinary Panel, within 20 days of receiving 

the order of the Disciplinary Panel, by filing a notice of appeal with the Chief Compliance Officer.

While an appeal is pending, the effect of the order of the Disciplinary Panel or the summary action (including 

any sanctions, remedies or costs imposed thereby) shall be suspended. 
CMSEF Rulebook CMSEF Page 44

The notice of appeal must state in writing the grounds for appeal, including the findings of fact, conclusions 

or sanctions to which the respondent objects. An appellant may appeal the order of the Disciplinary Panel or 

any summary action on the grounds that: 

(i) the order or summary action was arbitrary, capricious, an abuse of discretion, or not in 

accordance with these Rules; 

(ii) the order or summary action exceeded the authority or jurisdiction of the Disciplinary Panel, 

the Chief Compliance Officer or CMSEF; 

(iii) the order or summary action failed to observe required procedures; 

(iv) the order or summary action was unsupported by the facts or evidence; or 

(v) the sanctions, remedies or costs, which were imposed, were inappropriate or unsupported by 

the record. 

The Chief Compliance Officer will forward copies of any notice of appeal received by it to all parties to the 

Disciplinary Proceeding or summary action, as the case may be, except the appellant. On or before the 20th 

day after filing a notice of appeal, the appellant must file with the Chief Compliance Officer and serve on the 

Compliance Department a brief supporting the notice of appeal and documents supporting the brief. On or 

before the 20th day after the date on which the appellant serves their supporting brief, the appellee must file 

and serve its brief in opposition. On or before the 10th day after the date on which the appellee serves its 

brief in opposition, the appellant must file and serve a brief in reply on the Compliance Department. 

In connection with any appeal, the Compliance Department will furnish to the Chief Compliance Officer and 

to the respondent/appellant a transcript of the hearing, any exhibits introduced at the hearing, the notice of 

appeal and briefs filed to support and oppose the appeal. 

No later than 30 days after the last submission filed pursuant to this Rule, the Chief Compliance Officer will 

appoint an Appeals Panel to consider and determine the appeal. An Appeals Panel shall be comprised of

three individuals, none of whom shall be a member of the Compliance Department or have been a member 

of any Disciplinary Panel involved in the matters on appeal. The chairman of the Appeals Panel shall be an 

individual who would not be disqualified from serving as a Public Director.

Within 10 days of being notified of the appointment of the Appeals Panel, a respondent may seek to disqualify 

any individual named to the Appeals Panel for the reasons identified in these Rules, by serving written notice 

on the Chief Compliance Officer. By not filing a timely request for disqualification, the respondent will be 

deemed to have waived any objection to the composition of the Appeals Panel. The Chief Compliance 

Officer will decide the merits of any request for disqualification within his or her sole discretion. Any such 

decision will be final and not subject to appeal. 

The Appeals Panel may hold a hearing to allow parties to present oral arguments. Any hearing will be 

conducted privately and confidentially. Notwithstanding the confidentiality of hearings, the Appeals Panel 

may appoint an expert to attend any hearing and assist in the deliberations if such individuals agree to be 

subject to appropriate confidentiality agreements. In determining procedural and evidentiary matters, the 

Appeals Panel will not be bound by evidentiary or procedural rules or law. 

The Appeals Panel will only consider on appeal the record before the Disciplinary Panel or, in the case of a 

summary action, the record considered by the Chief Compliance Officer, the notice of appeal, the briefs filed 

in support and opposition of the appeal, and any oral arguments of the parties. The Appeals Panel may only 

consider new evidence when the Appeals Panel is satisfied that good cause exists for why the evidence was 

not introduced during the Disciplinary Proceeding or when imposing the summary action. 

After completing its review, the Appeals Panel may affirm, modify or reverse any order of the Disciplinary 

Panel or summary action under appeal, in whole or in part, including increasing, decreasing or eliminating 

any sanction or remedy imposed, imposing any other sanction or remedy authorized by these Rules, or 

remanding the matter to the same or a different Disciplinary Panel for further Disciplinary Proceedings or 

for reconsideration by the Chief Compliance Officer in the case of summary action. The Appeals Panel may 

order a new hearing for good cause or if the Appeals Panel deems it appropriate. 
CMSEF Rulebook CMSEF Page 45

As promptly as reasonably possible following its review, the Appeals Panel will issue a written decision on 

appeal rendering its decision based on the weight of the evidence before the Appeals Panel. The decision of 

the Appeals Panel will include a statement of findings of fact and conclusions for each finding, sanction, 

remedy and cost reviewed on appeal, including each specific Rule and provision of applicable law that the 

respondent is found to have violated, if any, and the imposition of sanctions, remedies and costs, if any, and 

the effective date of each sanction, remedy or cost. 

The Appeals Panel’s written order on appeal (including findings of fact and conclusions and the imposition 

of sanctions, remedies and costs, and the effective date of any sanction, remedy cost) will be the final action 

of CMSEF and will not be subject to appeal within CMSEF.

Rule 520 Summary Imposition of Fines 

The Chief Compliance Officer may summarily impose a fine against a Participant (on behalf of itself or any 

of its Authorized Persons, Authorized Users, or Customers, or other Persons using any of its User IDs), 

Clearing Member, or Authorized User for failing: 

(i) to timely pay fees, cost, charges or fines to CMSEF or a DCO; 

(ii) to make timely and accurate submissions to CMSEF of notices, reports or other 

information required by these Rules; and 

(iii) to keep any books and records required by these Rules. 

The Compliance Department, acting on behalf of the Chief Compliance Officer, will give notice of any fine 

imposed pursuant to this Rule to each Participant or Authorized User subject thereto. The notice will specify:

(i) the violation of these Rules for which the fine is being imposed;

(ii) the date of the violation; and 

(iii) the amount of the fine. Within 20 days of serving the notice of fine, the Participant, or 

Authorized User, as the case may be, must either pay or cause the payment of the fine or 

file notice of an appeal pursuant to these Rules. Unless timely notice of appeal is filed 

pursuant to these Rules, the fine will become final upon the expiration of 20 days after the 

notice of fine is served on the Participant, or Authorized User, as the case may be. 

CMSEF will set the amount of any fines imposed pursuant to this Rule, with the maximum fine for each 

violation not to exceed $5,000. Summary imposition of fines pursuant to this Rule will not preclude CMSEF 

from bringing any other action against the Participant, or Authorized User, as the case may be. 

Rule 521 Summary Suspensions and Other Summary Actions 

Notwithstanding anything in these Rules to the contrary, if the Chief Compliance Officer reasonably believes 

that immediate action is necessary to protect the best interests of CMSEF or the marketplace, the Chief 

Compliance Officer may, after consultation with the Regulatory Oversight Committee summarily suspend, 

revoke, limit, condition, restrict or qualify the Trading Privileges of a Participant or Authorized User and 

take other summary action against a Participant or any of its Authorized Users in accordance with these 

Rules. 

Whenever practicable, the Compliance Department, acting on behalf of the Chief Compliance Officer, shall 

provide prior written notice to the party against whom any action in accordance with this Rule shall be taken. 

If prior notice is not practicable, CMSEF will give notice at the earliest possible opportunity to the respondent 

against whom the action is brought. The Compliance Department, acting on behalf of the Chief Compliance 

Officer, will prepare a notice of summary action (which will state the action, the reasons for the action, and 

the effective time, date and duration of the action) and serve the notice on such party and advise the recipient 

of the notice of its right to a prompt hearing before a Disciplinary Panel and its right to be represented by 

legal counsel or other representative at such hearing. A request by the recipient of the notice for such a 

hearing shall not delay the effectiveness of the summary action. 
CMSEF Rulebook CMSEF Page 46

At the request of CMSEF, a respondent against whom a summary action is brought pursuant to this Rule 

must provide books and records over which the respondent has access or control and must furnish information 

to, or appear or testify before, CMSEF or the Disciplinary Panel with the enforcement of any Rule. 

If a hearing is requested pursuant to this Rule, the Disciplinary Panel will promptly convene a hearing to be 

conducted in accordance with these Rules.

As promptly as reasonably possible after the hearing, the Disciplinary Panel will issue to the respondent a 

written order affirming, modifying, or reversing the summary action. The order will include a description of 

the summary action taken, a summary of the evidence introduced at the reinstatement hearing, a statement of 

findings of fact and conclusions, a description of any action taken or to be taken by CMSEF, and the effective 

date, time and duration thereof. 

Any decision of a Disciplinary Panel pursuant to this Rule will be the final action of CMSEF, and not subject 

to appeal within CMSEF upon serving the respondent with a copy of the decision. 

Rule 522 Reinstatement after Summary Suspension 

A respondent whose Trading Privileges are suspended, revoked, limited, conditioned, restricted or qualified 

pursuant to these Rules may apply for reinstatement by filing with the Compliance Department a written 

request stating the applicant’s reasons for seeking reinstatement. CMSEF will not consider a respondent’s 

request for reinstatement if the respondent 

(i) owes any fines, fees, charges or costs to CMSEF, 

(ii) continues to fail to appear at Disciplinary Proceedings without good cause or 

(iii) continues to impede the progress of Disciplinary Proceedings. 

Within a reasonable period after the filing of a request for reinstatement, the Appeals Panel will conduct a 

hearing to consider the request. At the hearing for reinstatement, the respondent will present its, his case 

supporting the reinstatement and the Compliance Department, acting on behalf of the Chief Compliance 

Officer may, in its discretion, present its case opposing or supporting the reinstatement and each may present 

relevant and admissible evidence and facts and call, examine and cross-examine witnesses. At the hearing 

for reinstatement, CMSEF may require Participants, Authorized Persons, Authorized Users, Clearing 

Members, or Participant’s Customers to appear as witnesses and produce evidence if the Appeals Panel 

determines that the evidence is relevant. 

As promptly as reasonably possible after a reinstatement hearing, the Appeals Panel will issue an order 

reinstating, denying the reinstatement, or placing conditions on the reinstatement of the Trading Privileges 

of the respondent. The order will include a brief summary of the evidence introduced at the reinstatement 

hearing; and, if applicable, findings of fact and conclusions not contained in the notice of summary action 

issued pursuant to these Rules. The order of the Appeals Panel may not be appealed. 

Rule 523 Rights and Responsibilities after Suspension or Termination 

When the Trading Privileges of a Participant or Authorized User are suspended for a period of 12 months or 

less, none of its rights and Trading Privileges (including the right to hold oneself out to the public as a 

Participant or Authorized User or enter Orders or RFQs into the SEF and receive Participant rates for fees, 

costs, and charges and deposit margin at Participant levels) will apply to such Participant, Authorized Person 

or Authorized User during the period of the suspension, except for the right to assert claims against others as 

provided in these Rules. Any such suspension will not affect the rights of creditors under these Rules or 

relieve the Participant or Authorized User of its obligations under these Rules to perform any Swaps entered 

into before the suspension, or for any Company fees, costs, or charges incurred during the suspension. 

CMSEF may discipline a suspended Participant, Authorized Person or Authorized User under this Chapter 5 

for any violation of a Rule or provision of applicable law committed by the Participant or Authorized User 

before, during or after the suspension.
CMSEF Rulebook CMSEF Page 47

When the Trading Privileges of a Participant or Authorized User are terminated, all of its rights and Trading 

Privileges will terminate, except for the right of the Participant, Authorized Person or Authorized User in 

question to assert claims against others, as provided in these Rules. Any such termination will not affect the 

rights of creditors under these Rules. A terminated Participant or Authorized User may only seek to reinstate 

his Trading Privileges by providing CMSEF with satisfactory evidence that he complies with these Rules. 

CMSEF will not consider the application of a terminated Participant or Authorized User if such Participant 

or Authorized User, as the case may be, fails to appear at Disciplinary Proceedings without good cause or 

impedes the progress of Disciplinary Proceedings. 

A suspended or terminated Participant or Authorized User remains subject to these Rules and the jurisdiction 

of CMSEF for any acts or omissions prior to the suspension or termination, and must cooperate in any 

Investigation, Disciplinary Proceeding, appeal from Disciplinary Proceedings, summary suspension or other 

summary action as if the suspended or terminated Participant or Authorized User still had Trading Privileges. 

Rule 524 Notice of Disciplinary Proceedings 

CMSEF will provide written notice of Disciplinary Proceedings to the parties and the RSP consistent with 

applicable CFTC Regulations. Whenever CMSEF suspends, expels, fines or otherwise disciplines, or denies 

any Person access, to CMSEF, CMSEF will make the public disclosures required by CFTC Regulations.

Rule 525 CFTC Review of CMSEF Actions

The review by the CFTC, pursuant to section 8c of the Act, as amended, of any suspension, expulsion, 

disciplinary or access denial action, or other adverse action by CMSEF, shall be governed by Part 9 of the 

CFTC’s Regulations.
