17 CFR 38.253: Additional requirements for cash-settled contracts.

(a) For cash-settled contracts, the designated contract market must demonstrate that it:

(1) Monitors the pricing of the index to which the contract will be settled; and

(2) Monitors the continued appropriateness of the methodology for deriving the index and makes a good-faith effort to resolve conditions, including amending contract terms where necessary, where there is a threat of market manipulation, disruptions, or distortions.

(b) If a contract listed on a designated contract market is settled by reference to the price of a contract or commodity traded in another venue, including a price or index derived from prices on another designated contract market, the designated contract market must have rules or agreements that allow the designated contract market access to information on the activities of its traders in the reference market.
