The Exchanges are implementing the Rule Amendments to remove obsolete references in certain CME 

and CBOT option product chapters. CME Group’s long-standing policy regarding corrections to CME, 

CBOT, New York Mercantile Exchange, Inc. (“NYMEX”) and Commodity Exchange, Inc. (“COMEX”) option 

exercise instructions will also be posted on the CME Group website.

Appendix A below provides the Rule Amendments in blackline format. 

The Exchanges 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: 

Availability of General Information: The Exchanges will amend the online rulebooks accordingly 

on the effective date which is publicly available on the CME Group website.

Daily Publication of Trading Information: The Exchanges will continue to publish contract trading 

volumes, open interest levels, and price information daily on its website and through quote vendors 

for the Contracts.

Prevention of Market Disruption: Trading in the Contracts will continue to be subject to the rules 

of the Exchanges, which include prohibitions on manipulation, price distortion, and disruption to the 

cash settlement process.

Compliance with Rules: The Exchanges will continue its normal practice to establish, monitor, 

and enforce compliance with the rules of the Contracts. 

Pursuant to Section 5c(c) of the Act and Regulation 40.6(a), the Exchanges certify that the Rule 

Amendments comply with the Act, including all regulations thereunder. There were no substantive 

opposing views to this proposal.

The Exchanges certify that this submission has been concurrently posted on the Exchanges’ website at 

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

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