Dear Mr. Kirkpatrick:

Pursuant to Commodity Futures Trading Commission (“CFTC” or “Commission”) Regulation 40.6(a), NEX 

SEF Limited (“NEX SEF”) certifies to the Commission amendments to certain exhibits of its Form SEF to 

reflect changes to composition of the NEX SEF’s Board of Directors as more specifically described below 

(collectively, the Rule Amendments”) effective on December 30, 2020.

The following exhibits to the NEX SEF Form SEF shall be amended:

1. Exhibit B1 – SEF Officers, Directors and Committee Members;

2. Exhibit C – Fitness Standards; and

3. Exhibit G3 – Governance Policy.

NEX SEF reviewed the swap execution facility core principles (“Core Principles”) as set forth in the 

Commodity Exchange Act (“CEA” or Act”) and identified that the following Core Principles may be impacted 

by the Rule Amendments:

• SEF Core Principle 2 – Compliance with Rules: As a result of the changes to the composition to 

the NEX SEF Board of Directors, the Rule Amendments are being implemented to remain in 

satisfaction of this Core Principle.

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

Amendments comply with the Act and the Commission’s regulations thereunder. There were no substantive 

opposing views to this proposal.
