EXPLANATION AND ANALYSIS OF THE CONTRACT’S COMPLIANCE WITH APPLICABLE CORE

PRINCIPLES AND COMMISSION REGULATIONS

As required by Commission Regulation § 40.2(a), the following analysis demonstrates that the 

Contract is consistent with the requirements of the Act and the Commission regulations and 

policies thereunder (in particular, Appendix B to Part 37 and Appendix C to Part 38, 

respectively). 

Appendix B to Part 37—Demonstration of Compliance That a Contract Is Not Readily

Susceptible to Manipulation

Core Principle 3 of Section 5h of the Act—Swaps Not Readily Susceptible to Manipulation. 

The swap execution facility shall permit trading only in swaps that are not readily susceptible 

to manipulation.

(a) Guidance.

(1) In general, a swap contract is an agreement to exchange a series of cash flows over a

period of time based on some reference price, which could be a single price, such as an

absolute level or a differential, or a price index calculated based on multiple observations.

Moreover, such a reference price may be reported by the swap execution facility itself or by

an independent third party. When listing a swap for trading, a swap execution facility shall

ensure a swap’s compliance with Core Principle 3, paying special attention to the reference

price used to determine the cash flow exchanges. Specifically, Core Principle 3 requires that

the reference price used by a swap not be readily susceptible to manipulation. As a result,

when identifying a reference price, a swap execution facility should either: Calculate its own

reference price using suitable and well-established acceptable methods or carefully select a

reliable third-party index.

(2) The importance of the reference price’s suitability for a given swap is similar to that of the 

final settlement price for a cash-settled futures contract. If the final settlement price is 

manipulated, then the futures contract does not serve its intended price discovery and risk 

management functions. Similarly, inappropriate reference prices cause the cash flows 

between the buyer and seller to differ from the proper amounts, thus benefitting one party 

and disadvantaging the other. Thus, careful consideration should be given to the potential for 

manipulation or distortion of the reference price.

Reference Index: North American High Yield CDX (BB) Index

The reference index used to determine the exchange of payments for the Contract is a subindex

of Markit’s North America High Yield CDX Index, or the CDX.NA.HY Index. This index, Markit’s 

North American High Yield CDX (BB) Index (the “Index”), was initially composed of 41 entities 

with a BB credit rating that are constituents of Markit’s North American High Yield CDX Index.

The Index is owned, managed, compiled and published by IHS Markit (the “Administrator”). IHS 

Markit Benchmark Administration Ltd. (“IMBA UK”) is authorised by the UK FCA as Benchmark 

Administrator in July 2018 and complies with the UK Benchmarks Regulation. IMBA UK is listed 

as authorised Benchmark Administrator on the FCA Benchmarks register. The composition of 

the Index is determined by the Administrator in accordance with the rules and methodologies 

set forth in the Index Rules.1If the Administrator determines that an event has had a material 

impact on the integrity of one or more Index-related transactions, including but not limited to 

trading interruptions, market instability and/or force majeure events, the Administrator, acting 

in an independent and reasonable manner, may determine that it is appropriate to depart from 

the methodologies, timelines and/or procedures set forth in the Rules to obtain a result that 

preserves the economic intent of such Index. As this Index is based on clear, widely-available, 

comprehensive and transparent rules, it is not readily susceptible to manipulation.

(3) For swaps that are settled by physical delivery or by cash settlement refer to the guidance 

in appendix C to part 38 of this chapter—Demonstration of Compliance That a Contract is not 

Readily Susceptible to Manipulation, section b(2) and section c(4), respectively. 

Appendix C to Part 38 - Demonstration of Compliance That a Contract Is Not Readily 

Susceptible to Manipulation

(c) Futures Contracts Settled by Cash Settlement. (1) Cash settlement is a method of settling 

certain futures or option contracts whereby, at contract expiration, the contract is settled by 

cash payment in lieu of physical delivery of the commodity or instrument underlying the 

contract. An acceptable specification of the cash settlement price for commodity futures and

option contracts would include rules that fully describe the essential economic characteristics 

of the underlying commodity (e.g., grade, quality, weight, class, growth, issuer, maturity, 

source, rating, description of the underlying index and index’s calculation methodology, etc.), 

as well as how the final settlement price is calculated. In addition, the rules should clearly 

specify the trading months and hours of trading, the last trading day, contract size, minimum 

price change (tick size) and any limitations on price movements (e.g., price limits or trading 

halts).

Terms of the Contract

The terms and conditions of the Contract are in Attachment A. As described in Attachment A, 

some terms of the Contract are fixed (i.e., currency and index), while other terms are flexible 

and determined by the counterparties (i.e., effective date and maturity date). This combination 

of standard and flexible terms allows the Contract to have a basic consistent form, while 

allowing counterparties to tailor some aspects of the Contract to their economic needs. This 

structure follows industry convention; the terms of the Contract match the terms of credit 

default swaps that are commonly offered in the market.

Calculation of Cash Settlement Price

The contract is financially settled. The settlement process for the Contract includes the 

following payments:

• Contingent payment: Payments related to credit event settlement will be determined 

pursuant to the 2009 ISDA Credit Derivatives Determination Committees and Auction 

Settlement Supplement (i.e., the Big Bang Protocol).

• Fixed Quarterly cash payments: Reflected in basis points and paid by the protection 

buyer to the protection seller.

• Upfront fee payment: The upfront fee is a portion of the payments, expressed in 

percentage points of the notional, which is present valued and paid immediately to the 

seller.

This settlement method for credit default swaps is often used for credit default swaps, and thus 

widely accepted by market participants.

2) Cash settled contracts may be susceptible to manipulation or price distortion. In evaluating 

the susceptibility of a cash-settled contract to manipulation, a designated contract market 

should consider the size and liquidity of the cash market that underlies the listed contract in a 

manner that follows the determination of deliverable supply as noted above in (b)(1). In

particular, situations susceptible to manipulation include those in which the volume of cash 

market transactions and/or the number of participants contacted in determining the cashsettlement price are very low. Cash-settled contracts may create an incentive to manipulate 

or artificially influence the data from which the cash-settlement price is derived or to exert 

undue influence on the cash-settlement price’s computation in order to profit on a futures 

position in that commodity. 
4

#600792265v5

The utility of a cash-settled contract for risk management and price discovery would be 

significantly impaired if the cash settlement price is not a reliable or robust indicator of the 

value of the underlying commodity or instrument. Accordingly, careful consideration should 

be given to the potential for manipulation or distortion of the cash settlement price, as well 

as the reliability of that price as an indicator of cash market values. Appropriate 

consideration also should be given to the commercial acceptability, public availability, and 

timeliness of the price series that is used to calculate the cash settlement price. 

Documentation demonstrating that the settlement price index is a reliable indicator of 

market values and conditions and is commonly used as a reference index by industry/market 

agents should be provided. Such documentation may take on various forms, including 

carefully documented interview results with knowledgeable agents.

The Contract is not readily susceptible to manipulation for a number of reasons. First, the 

underlying asset for the Contract is an excluded commodity as defined in section 1a(19) of the 

Commodity Exchange Act, making manipulation very difficult to achieve. Second, the 

management and calculation of the reference price is based on clear and comprehensive rules. 

Third, as noted above, the method for calculating the cash settlement price – involving upfront 

fee payments, fixed quarterly cash payments, and (in the case of a credit event) a contingent 

payment – is widely used and generally accepted by market participants. And last, BSEF has a 

market surveillance program that is designed to surveil this market, detect uncommon activity, 

and investigate any such activity for signs of manipulation. 

(3) Where an independent, private-sector third party calculates the cash settlement price 

series, a designated contract market should consider the need for a licensing agreement that 

will ensure the designated contract market’s rights to the use of the price series to settle the 

listed contract.

(i) Where an independent, private-sector third party calculates the cash settlement price 

series, the designated contract market should verify that the third party utilizes business 

practices that minimize the opportunity or incentive to manipulate the cash-settlement price 

series. Such safeguards may include lock-downs, prohibitions against derivatives trading by 

employees, or public dissemination of the names of sources and the price quotes they 

provide. Because a cash-settled contract may create an incentive to manipulate or artificially 

influence the underlying market from which the cash-settlement price is derived or to exert 

undue influence on the cash-settlement computation in order to profit on a futures position 

in that commodity, a designated contract market should, whenever practicable, enter into an 

information-sharing agreement with the third-party provider which would enable the 

designated contract market to better detect and prevent manipulative behavior.

Please see above regarding the calculation of the settlement price. 

(ii) Where a designated contract market itself generates the cash settlement price series, the 

designated contract market should establish calculation procedures that safeguard against 
5

#600792265v5

potential attempts to artificially influence the price. For example, if the cash settlement price 

is derived by the designated contract market based on a survey of cash market sources, the 

designated contract market should maintain a list of such entities which all should be 

reputable sources with knowledge of the cash market. In addition, the sample of sources 

polled should be representative of the cash market, and the poll should be conducted at a 

time when trading in the cash market is active.

Please see above regarding the calculation of the settlement price. 

(iii) The cash-settlement calculation should involve computational procedures that eliminate 

or reduce the impact of potentially unrepresentative data.

(iv) The cash settlement price should be an accurate and reliable indicator of prices in the 

underlying cash market. The cash settlement price also should be acceptable to commercial 

users of the commodity contract. The registered entity should fully document that the 

settlement price is accurate, reliable, highly regarded by industry/market agents, and fully 

reflects the economic and commercial conditions of the relevant designated contract market.

Please see above regarding the availability, reliability and widespread acceptance of the 

method used to generate the settlement price.

(v) To the extent possible, the cash settlement price should be based on cash price series that 

are publicly available and available on a timely basis for purposes of calculating the cash 

settlement price at the expiration of a commodity contract. A designated contract market 

should make the final cash settlement price and any other supporting information that is 

appropriate for release to the public, available to the public when cash settlement is 

accomplished by the derivatives clearing organization. If the cash settlement price is based on 

cash prices that are obtained from non-public sources (e.g., cash market surveys conducted 

by the designated contract market or by third parties on behalf of the designated contract 

market), a designated contract market should make available to the public as soon as 

possible after a contract month’s expiration the final cash settlement price as well as any 

other supporting information that is appropriate or feasible to make available to the public.

Information on the Index is available on markit.com. 

(4) Contract terms and conditions requirements for futures contracts settled by cash 

settlement.

(i) An acceptable specification of the terms and conditions of a cash-settled commodity 

contract will also set forth the trading months, last trading day, contract size, minimum price 

change (tick size) and daily price limits, if any.

Also as noted in the attached, the counterparties will begin calculating accrued obligations from 

the effective date to the maturity date (i.e., “last trading day”) of each contract – dates which 
6

#600792265v5

are set by the counterparties. The minimum size is determined by the counterparties, as is 

customary for contracts of this type.

(A) Commodity Characteristics: The terms and conditions of a commodity contract should 

describe the commodity underlying the contract.

The terms and conditions of the Contract note that the Contract is based on a basket of high 

yield North American entities with a BB credit rating. 

(B) Contract Size and Trading Unit: An acceptable specification of the trading unit would be a 

contract size that is consistent with customary transactions in the cash market. A designated 

contract market may opt to set the contract size smaller than that of standard cash market 

transactions.

The size of the Contract, which is determined by the counterparties, is consistent with 

customary transactions in the market.

(C) Cash Settlement Procedure: The cash settlement price should be reliable, acceptable, 

publicly available, and reported in a timely manner as described in paragraphs (c)(3)(iv) and 

(c)(3)(v) of this appendix C.

The settlement procedure and an explanation of how it is reliable, acceptable, publicly 

available, and reported in a timely manner appears above.

(D) Pricing Basis and Minimum Price Fluctuation (Minimum Tick): The minimum price 

increment (tick) should be set a level that is equal to, or less than, the minimum price 

increment commonly observed in cash market transactions for the underlying commodity. 

Specifying a futures’ minimum tick that is greater than the minimum price increment in the 

cash market can undermine the risk management utility of the futures contract by preventing 

hedgers from efficiently establishing and liquidating futures positions that are used to hedge 

anticipated cash market transactions or cash market positions.

The quoting convention of the Contract and minimum increment are based on the industry 

standard, as there is no cash market for the Index.

(E) Maximum Price Fluctuation Limits: Designated contract markets may adopt price limits to: 

(1) Reduce or constrain price movements in a trading day that may not be reflective of true 

market conditions but might be caused by traders overreacting to news; (2) Allow additional 

time for the collection of margins in times of large price movements; and (3) Provide a 

“cooling-off” period for futures market participants to respond to bona fide changes in 

market supply and demand fundamentals that would lead to large cash and futures price 

changes. If price-limit provisions are adopted, the limits should be set at levels that are not 

overly restrictive in relation to price movements in the cash market for the commodity 

underlying the futures contract. For broad-based stock index futures contracts, rules should 
7

#600792265v5

be adopted that coordinate with New York Stock Exchange (“NYSE”) declared Circuit Breaker 

Trading Halts (or other market coordinated Circuit Breaker mechanism) and would 

recommence trading in the futures contract only after trading in the majority of the stocks 

underlying the index has recommenced.

See BSEF Rule 535.

(F) Last Trading Day: Specification of the last trading day for expiring contracts should be 

established such that it occurs before publication of the underlying third-party price index or 

determination of the final settlement price. If the designated contract market chooses to 

allow trading to occur through the determination of the final settlement price, then the 

designated contract market should show that futures trading would not distort the final 

settlement price calculation.

The last trading day is the maturity date of the contract, which is set by the counterparties. 

(G) Trading Months: Trading months should be established based on the risk management 

needs of commercial entities as well as the availability of price and other data needed to 

calculate the cash settlement price in the specified months. Specification of the last trading 

day should take into consideration whether the volume of transactions underlying the cash 

settlement price would be unduly limited by occurrence of holidays or traditional holiday 

periods in the cash market. Moreover, a contract should not be listed past the date for which 

the designated contract market has access to use a proprietary price index for cash 

settlement.

If there is no credit event, the protection buyer will pay the protection seller fixed quarterly 

cash payments. 

(H) Speculative Limits: Specific rules and policies for speculative position limits are set forth in 

part 150 and/or part 151, as applicable, of the Commission’s regulations.

BSEF will comply with Parts 150 and 151 of the Commission’s regulations.

(I) Reportable Levels: Refer to § 15.03 of the Commission’s regulations.

BSEF will adhere to the applicable reporting levels set forth in § 15.03 of the Commission’s 

regulations.

(J) Trading Hours: Should be set by the designated contract market to delineate each trading 

day. 

The Contract is traded twenty-four hours a day (00:01 – 24:00) (EST), Sunday to Friday.
