Re: CFTC Regulation 40.6(a) Certification. Migration of Open Interest from the Options 

on E-mini S&P 500 Index Futures – Quarterly PM (European-Style) Contract to the 

Weekly Options on E-mini S&P 500 Index Futures – Week 3 (European-Style) 

Contract.

CME Submission No. 22-536 (2 of 2)

Dear Mr. Kirkpatrick:

Chicago Mercantile Exchange Inc. (“CME” or “Exchange”), a registered designated contract market 

(“DCM”) and derivatives clearing organization (“DCO”) under the Commodity Exchange Act, as amended 

(“CEA” or “Act”), is certifying to the Commodity Futures Trading Commission (“CFTC” or “Commission”) 

rule amendments to facilitate the conversion of unexpired open positions in the Options on E-mini S&P 500 

Index Futures – Quarterly PM (European-Style) contract (the “Quarterly Contract”) at the close of business 

on Friday, February 10, 2023 into notionally equivalent positions in the Weekly Options on E-mini S&P 500 

Index Futures – Week 3 (European-Style) contract (the “Weekly Contract”). Following completion of the 

conversion process on February 12, 2023, there will be zero (0) open interest in the Quarterly Contract and 

it will be immediately delisted. 

In order to facilitate the conversion process and delisting of the Quarterly Contract, CME will:

1. Expand the listing schedule for the Weekly Contract from 9 non-consecutive week 3 contracts 

(excluding quarterly months) to 13 consecutive week 3 contracts (including quarterly months);

2. Terminate trading and trade submissions in the Quarterly Contract at close of business on trade 

date February 10, 2023; 

3. Implement the conversion process as further described below and in Exhibit A (Form of Advisory 

Notice); 

4. Delist the Quarterly Contract and make all necessary revisions to the CME Rulebook and website 

as further described below and in Exhibit B (effective immediately upon completion of the 

conversion process); and

5. Amend the Position Limit, Position Accountability and Reportable Level Table in Chapter 5 of the 

CME Rulebook as further described below and in Exhibit C (collectively, the “Rule Amendments”).

Background

In June 2021, CME listed the Quarterly Contract as a solution for option box traders in the aftermath of the 

S&P 500 Options open outcry, trading floor closure. The Quarterly Contract provides option box traders 

with access to a European-style option expiry on the 3rd Friday of quarterly months (March, June,

September, December), a key date for liquidity provision in the futures and options markets. 

Previously the Exchange implemented amendments to the daily settlement of all options on E-mini and 

Micro S&P 500 Index futures contracts. As a result of those amendments, the Weekly Contract was 

essentially equalized with the Quarterly Contract. See CME Submission No. 22-329 dated November 1, 

2022.

The planned conversion of the Quarterly Contract will have zero (0) economic value change. 

Upon the effective date of this Submission, the existing option box strategies will continue to be available 

utilizing the Weekly Contract. 

Engagement with Market Participants

In connection with the Rule Amendments, market participants expressed support for the proposal to convert 

existing open interest in the Quarterly Contract to the notionally equivalent Weekly Contract.

Substantive Opposing Views

There were no substantive opposing views raised with respect to the conversion process reflected in the 

text of the Advisory Notice. Clearing Members and market participants have been generally supportive of 

the proposed conversion and delisting.

Analysis under DCM and DCO Core Principles

The Exchange reviewed the designated contract market core principles (“Core Principles”) as set forth in 

the Commodity Exchange Act (“CEA” or “Act”) and identified that the Rule Amendments may have some 

bearing on the following Core Principles:

DCM Core Principles

Compliance with Rules: CME Globex trading and trade submissions in the Quarterly Contract will 

terminate at the normal close of business time on February 10, 2023. All Quarterly Contract

positions that are unexpired at that time will be converted into notionally equivalent Weekly Contract

positions during the conversion period. Neither voluntary offset or closure of Quarterly Contract

3

positions prior to the conversion period nor mandatory conversion during the conversion period will 

impact the Exchange’s ability to monitor or enforce compliance with its Rules.

Contracts Not Readily Subject to Manipulation: The Quarterly Contract and the Weekly Contract 

counterparts settle to the same index. 

Prevention of Market Disruption: The conversion process supports CME’s ability to prevent 

market disruption or price distortion, which could otherwise occur where liquidity in the Quarterly 

Contract gradually diminishes as they expire and roll off, or where they are listed for trading on

CME Globex to trade side-by-side with the Weekly Contract, which would unnecessarily bifurcate 

liquidity across two screen-based products that serve the same risk management needs. Further, 

at the time of delisting there will be no open interest in the Quarterly Contract and therefore there 

will be no market disruption related to their delisting.

Position Limitations or Accountability: Position limits for the Weekly Contract resulting from the 

conversion will be maintained at current levels, which are equivalent to those for the Quarterly 

Contract after adjusting for the notional size basis between the respective contracts.

Execution of Transactions: The Exchange will continue its current practice of providing a 

competitive, open, and efficient market mechanism for executing transactions in the Weekly

Contract, including the expansion of the listing schedule of the Weekly Contract.

Trade Information: The Clearing House will convert the Quarterly Contract positions into notionally 

equivalent Weekly Contract positions. The mechanism for conversion supports electronic 

confirmations to Clearing Members, regulatory reporting and accurate audit trail data. Positions 

resulting from the conversion will be reflected on Clearing Member trade registers and CME 

Group’s Daily Bulletin, which shows volume and open interest for all products.

Recordkeeping: Records pertaining to the conversion process will remain subject to 

recordkeeping requirements established in accordance with this Core Principle.

Antitrust Considerations: Termination of trading in the Quarterly Contract and conversion of open 

interest will enhance price discovery by transitioning to a deeper pool of liquidity and efficient 

execution on CME Globex. 

Availability of General Information: The Advisory Notice will be published on the CME Group 

website along with a related SER regarding the Rule Amendments. The SER will also be posted 

on the CME Group website. 

Daily Publication of Trading Information: The Exchange will continue to publish daily trading 

volumes, open interest levels, and price information for the Weekly Contract on the CME Group 

website and through quote vendors

DCO Core Principles

Risk Management: The conversion will not impact the Clearing House’s ability to manage risk. On 

a notionally adjusted basis the performance bond requirements for the Quarterly Contract and 

the Weekly Contract are the same.

Settlement Procedures: The conversion will not impact the Clearing House’s ability to effect 

settlement with its Clearing Members. All Quarterly Contracts will go through the EOD settlement 

cycle for February 10, with contracts expiring that day following the normal process for final 

settlement. All positions resulting from the conversion will be subject to daily and final settlement 

processes for the Weekly Contract.

Reporting: Positions subject to or resulting from the conversion process will be reflected on reports 

to the Commission in accordance with this Core Principle.

Recordkeeping: Records pertaining to the conversion process will remain subject to 

recordkeeping requirements established in accordance with this Core Principle.

Public Information: The Advisory Notice will be published on the CME Group website. CME will 

remove all references to the Quarterly Contract in the product rule chapters and from the CME 

Rulebook and website.

The text of the Advisory Notice is provided in Exhibit A.

The Advisory Notice is intended to be effective as of February 10, 2023, pending all relevant CFTC 

regulatory review periods. 

Pursuant to Section 5c(c) of the Act and CFTC Regulation 40.6(a), the Exchange hereby certifies that the 

Rule Amendments comply with the Act, including regulations under the Act. There were no substantive 

opposing views to the proposal. 

The Exchange certifies that this submission has been concurrently posted on the CME Group website at 

http://www.cmegroup.com/market-regulation/rule-filings.html.

Given the importance of EYC contract for risk management purposes, CME will expand the listing schedule 

of the existing Weekly Contract, specifically the week 3 contract (contract code EW3). The existing EW3 

contract has the same economic characteristics as the EYC contract and the listing expansion of EW3 will 

enable customers to trade contract expiries that previously only existed under the EYC contract. The 

expanded listing schedule of EW3 will be available for trading on CME Globex electronic trading platform 

(“CME Globex”) and for submission for clearing via CME ClearPort at 5:00 p.m. CT Sunday, February 12, 

2023, for trade date Monday, February 13, 2023.

Please note the behavior for the EYC contract is quarterly contracts (Mar, Jun, Sep, Dec) listed for 4 

consecutive quarters, with trading terminating on the 3rd Friday of the contract month. Currently EW3 

contract expiries are listed as 9 weekly contracts (excluding quarterly months) and trading terminates at 

3:00 p.m. CT on Friday of the contract week. With the listing expansion, this will change to 13 consecutive 

weekly contracts (including quarterly months) and trading will terminate at 3:00 p.m. CT on Friday of the 

contract week.

In order to support Clearing Members with open interest in EYC contracts after trading ceases at 4.00 p.m. 

CT on Friday February 10, 2023, CME Clearing will convert those positions into an equivalent strike and 

expiry in the EW3 contract. CME Clearing will be in touch will Clearing Members prior to the conversion 

weekend, however the conversion process will look as follows:

1. On Friday February 10, 2023, trading in the EYC contract will terminate at 4:00 p.m. CT. For Friday’s end 

of day clearing cycle, it is important that Clearing Members complete all their allocation activity in the EYC 

contract and ensure an accurate PCS is submitted given that Friday’s EOD positions will be used in the 

conversion process to establish the EW3 positions.

2. On Sunday February 12, 2023, prior to the trading open at 5:00 p.m. CT, CME Clearing will convert 

individual trading positions in outstanding EYC positions through establishing offsetting transfers in the 

Clearing Members’ account opposite the CME 995 account to establish notionally equivalent positions 

from EOD Friday into EW3 positions. For each 1 contract position a Clearing Member holds in the EYC 

contract, CME Clearing will process 2 transfers: 1 transfer offsetting the EYC position and 1 transfer 

onsetting an EW3 position. These transfers will be processed at a trade price of 0 and Clearing Members

will receive clearing confirmation messages for these transfers. CME Clearing will provide a file to clearing 

Members showing the transfers booked in the conversion process. At 5:00 p.m. on Sunday, the expanded 

listing schedule of the EW3 contract will be available for trading and clearing for trade date Monday

February 13, 2023.

3. On Monday February 13, 2023, should Clearing Members need to make any morning Position Change 

Submission (“PCS”) adjustments in the EYC contract as a result of an inaccurate PCS value from Friday, 

the open interest adjustments should be performed on the converted EW3 positions prior to the normal 

8:15 a.m. CT deadline. For the end of day clearing cycle on Monday, Clearing Members should submit a 

PCS value of 0 for their EYC positions or refrain from submitting a value for EYC positions altogether.

Should Clearing Members have any questions please call 312-207-2525 or email ccs@cmegroup.com.

358A01.J. [Reserved]

358A02. EXERCISE AND ASSIGNMENT

In addition to the applicable procedures and requirements of Chapter 7, the following shall apply to the

exercise of options.

358A02.A. Exercise

1. Quarterly Options

Any Quarterly option (Rule 358A01.D.1.) may be exercised by the buyer on any Business Day prior to

and including such option’s Expiration Date. To exercise such option, the clearing member

representing the option buyer shall present an exercise notice to the Clearing House by 5:30 p.m., or 

bysuch other time as the Exchange may designate, on the day of exercise.

Any unexercised option shall expire at 5:30 p.m. on the day scheduled for determination of the Final

Settlement Price (Rule 35803.A.) of such option’s Underlying Futures Contract. Any option that is in 

themoney, and that has not been liquidated or exercised prior to its termination of trading, shall be

exercised automatically upon expiration, in the absence of contrary instructions. Such contrary

instructions must be delivered to the Clearing House, by the clearing member representing the buyer 

of such option, no later than 5:30 p.m., or at such other time on such option’s Expiration Date as may 

be designated by the Exchange.

An expiring call option shall be in the money if the Final Settlement Price of such option’s Underlying
12

Futures Contract (Rule 358A01.D.) on such option’s Expiration Date is strictly above such option’s

exercise price, and shall be out of the money if such settlement price is at or below such option’s

exercise price.

An expiring put option shall be in the money if the Final Settlement Price of such option’s Underlying

Futures Contract on such option’s Expiration Date is strictly below such option’s exercise price,

and

shall be out of the money if such Final Settlement Price is at or above such option’s exercise price.

2. All Options Excluding Quarterly Options

Any European Style Weekly (Rule 358A01.D.2.), European Style Monday Weekly (Rule 

358A01.D.3.), European Style Tuesday Weekly (Rule 358A01.D.4.), Wednesday Weekly (Rule 

358A01.D.5.), Thursday Weekly (Rule 358A01.D.6.), or European Style End-of-Month (Rule 

358A01.D.7.), or European Style Quarterly PM (Rule 3538A01.D.8.) option may be exercised only at, 

and not before, the expiration of such option. Following termination of trading in expiring options, any 

such option that is in the money shall be automatically exercised by the Clearing House, and any such 

option that is out of the money shall be abandoned by the Clearing House. For the avoidance of doubt, 

no such option that expires in the money may be abandoned, and no such option that expires out of

the money may be exercised.

Whether an option expires in the money or out of the money shall be determined by the Exchange, in 

itssole discretion, by reference to the Fixing Price of such option’s Underlying Futures Contract (Rule

358A01.D.). The Exchange, in its sole discretion, shall set such Fixing Price on the last day of trading

in such option, as follows:

Tier 1

Such Fixing Price shall be based on the volume-weighted average price of transactions in such futures

on the CME Globex electronic trading platform during the interval (i) between 2:59:30 p.m. and 3:00:00

p.m., or (ii) in the case of an early scheduled close of the Primary Listing Exchange, between 11:59:30

a.m. and noon, or (iii) in the event of an unscheduled early close of the Primary Listing Exchange, the

final thirty (30) seconds of the Primary Listing Exchange trading day (“Reference Interval”).

Tier 2

If no such transaction occurs during the Reference Interval, then such Fixing Price shall be based

onthe average of midpoints of bid/ask spreads for such futures quoted on CME Globex during the

Reference Interval, provided that the Fixing Price calculation shall exclude the midpoint value for any

such bid/ask spread that is wider than 0.50 Index points (equal to two (2) minimum price increments).

Tier 3

If such Fixing Price cannot be determined pursuant to Tier 1 or Tier 2, then the Exchange, in its sole 

discretion, shall set such Fixing Price by alternative means which may include, but are not limited to, 

derivation by reference to the basis relationship between such futures contract’s price and the Index,

or application of Tier 1 or Tier 2, calculations to successive time intervals of increasing length, in integer

multiples of thirty (30) seconds, until suitable price data are obtained.

The resultant Fixing Price value shall be rounded to the nearest integer multiple of 0.01 Index points.

Such Fixing Price, so rounded, shall be used to determine whether an option expires in the money or

out of the money.

If, at the time such Fixing Price is scheduled to be calculated in respect of expiring options, the Primary

Listing Exchange (Rule 358A00.A.) is subject to a Regulatory Halt (Rule 358A00.B.), and the Primary

Futures Contract Month is limit offered at the maximum price limit permissible during such Regulatory

Halt pursuant to Rule 35802.I., then (a) such option shall expire at 8:31 a.m. on the next following

Business Day on which a Regulatory Halt is not in effect, and (b) the Fixing Price in respect of such

option shall be calculated in accordance with the corresponding provisions of this Rule, on the basis

ofa reference interval beginning at 8:30:30 a.m. and concluding at 8:31:00 a.m. If, during any portion 

of the 30-second period from 8:30:30 a.m. – 8:31:00 a.m. CT, there is a Level 1 or Level 2 Regulatory 

Haltin effect, the Fixing Price shall be calculated using trades consummated during the 30-second 

period commencing with the lifting of such Regulatory Halt. If a subsequent Regulatory Halt is declared 

during this 30-second period, the calculation of the Fixing Price shall be based strictly on those trades

consummated prior to such subsequent Regulatory Halt.

For the avoidance of doubt, in the event there is a Level 1 or Level 2 Regulatory Halt during the time

period of 8:30:30 – 8:31:00 am CT, no trades during that time period (8:30:30 – 8:31:00 am CT) will be

used in the calculation of the Fixing Price.

In the case that the underlying futures contract for a given European style option expires without any 

trading activity that would permit the calculation of the Fixing Price, then such Fixing Price will be equal 
13

to the Final Settlement Price of such option’s Underlying Futures Contract (Rule 358A01.D.) (For 

example, if there exists such a Regulatory Halt (Rule 358A00.B.) on the Thursday prior to the 3rd Friday 

in the March quarterly cycle, there may be no trading activity in the expiring futures upon which to 

predicate the Fixing Price).

An expiring call option shall be in the money if the corresponding Fixing Price is at or above such

option’s exercise price, and shall be out of the money if the corresponding Fixing Price is strictly below

such option’s exercise price.

An expiring put option shall be in the money if the corresponding Fixing Price is strictly below such

option’s exercise price, and shall be out of the money if the corresponding Fixing Price is at or above

such option’s exercise price.

358A02.B. Assignment

For a given option contract, an exercise notice accepted by the Clearing House in accordance with

Rules 358A02.A. shall be assigned by the Clearing House through a process of random selection to

clearing members carrying open short positions in such option contract. A clearing member to whom

such exercise notice has been assigned shall be notified thereof as soon as practicable following such

assignment.

The clearing member to whom such exercise notice has been assigned shall be assigned a short

position in such option’s Underlying Futures Contract (Rules 358A01.D.) if such option is a call, or a

long position in such option’s Underlying Futures Contract if such option is a put. The clearing member

representing the option buyer making exercise shall be assigned a long position in such option’s

Underlying Futures Contract if such option is a call, or a short position in such option’s Underlying

Futures Contract if such option is a put.

All such futures positions shall be assigned at a price equal to the exercise price of such option

contract, and shall be marked to market (in accordance with Rule 814) on the Business Day on which

the Clearing House accepts such exercise notice.
