Re: CFTC Regulation 40.6(d) Notification. Chicago Mercantile Exchange Inc. (“CME” or 

“Exchange”) Weekly Notification of Rule Amendments.

CME Submission No. 23-342

Dear Mr. Kirkpatrick:

Pursuant to Commodity Futures Trading Commission (“CFTC” or “Commission”) Regulation 40.6(d), the 

Exchange submits this weekly notification of the following rule amendments effective during the week of

July 31, 2023.

Effective August 3, 2023, the Exchange made an administrative correction to Exchange Rule 110.b. of 

Chapter 1 (“Membership”) to remove an obsolete reference to GFX Corporation (“GFX”). As described in 

Submission 18-165 dated April 16, 2018, GFX was decommissioned in March 2018. At that time, the 

Exchange removed all references to GFX from its Rulebook. This submission simply corrects an 

administrative error in Submission 18-165 and deletes an existing remaining reference to GFX. The 

administrative correction to Rule 110.b. is attached hereto in blackline format as Exhibit A.

Should you have any questions concerning the above, please contact the undersigned at (212) 299-2200 

or via e-mail at CMEGSubmissionInquiry@cmegroup.com.

Sincerely, 

/s/ Christopher Bowen

Managing Director and Chief Regulatory Counsel

110. CLAIMS AGAINST MEMBERSHIP, APPLICATION OF PROCEEDS

For the purposes of this rule "sale" shall include a sale made pursuant to Rule 104 or a transfer made in 

accordance with the provisions of Rule 106; "seller" shall include owners of a membership and firms that 

have membership privileges pursuant to Rules 106. F., G., H., I., J., N., R. or S.; and “claim” shall be 

limited to claims involving incidents that occurred prior to the sale of the membership and which arose in 

connection with Transactions on the Exchange or membership in the Exchange. For purposes of this 

Rule, “Transactions on the Exchange” shall include, but are not limited to, transactions receiving 

preferential clearing fees as a result of the membership, regardless of the party entitled to receipt of such 

preferential fees. Claims resulting from conduct subsequent to the sale of a membership may not be 

asserted against that membership or its proceeds. All claims against the membership or proceeds 

resulting from the sale of the membership shall be submitted in writing to the Department within 20 days 

of the posting of notice of the sale of said membership. At the conclusion of the 20-day claim filing period, 

authorized Exchange staff shall conduct an investigation of all claims properly filed against the 

membership sale or its proceeds. This investigation shall be completed within 20 days unless the 

investigation cannot be resolved within that period.

The total proceeds of the sale, or in the case of a transfer, the value at the mid-point of the bid-offer 

spread as of the date of the transfer, of the membership shall be applied to the following purposes and in 

the following order of priority:

a. Payment of all 1) debts owed to the Clearing House, if the membership transferred was assigned to 

the Clearing House pursuant to Rule 902; and 2) dues, fines, contributions, charges and other 

indebtedness owed to the Exchange or the CME Gratuity Fund;

b. Payment of any indebtedness to the clearing member who last qualified the selling member prior to 

the sale arising out of: (i) a pledge of such membership as collateral security on such indebtedness, 

or (ii) a deficit which authorized Exchange staff determines to have arisen directly out of Transactions 

on the Exchange or transactions with GFX Corporation;

c. Payment of amounts due to other clearing members on claims filed which authorized 

Exchange staff determines to have arisen directly out of Transactions on the Exchange;

d. Payment of amounts due to members and member firms on claims filed which authorized Exchange 

staff determines to have arisen directly out of Transactions on the Exchange; and

e. Payment of amounts due to public customers of the seller or public customers of any party receiving 

preferential clearing fees as a result of the membership based on claims filed by such customers or 

based on reports of the Market Regulation Department, which claims are determined by authorized 

Exchange staff to be based upon misappropriation of customer funds, improperly executed 

transactions, unpaid credit balances, or other similar matters, directly related to Transactions on the 

Exchange.

[The remainder of the Rule is unchanged]
