Dear Ms. Warfield:
The New York Mercantile Exchange, Inc. (“NYMEX” or “Exchange”) is notifying the Commodity Futures Trading
Commission (“CFTC” or “Commission”) that it is self-certifying an amendment to the last trading day for the LLS
(Argus) financial futures contract (chapter 838, commodity code XA) currently listed for trading on the NYMEX trading
floor and for submission for clearing through CME ClearPort. The last trading day for the LLS (Argus) financial
th
futures contract shall be amended from one business day prior to the last business day that falls on or before the 25
calendar day of the contract month to the last business day of the contract month, pursuant to Rule 838.06
(“Termination of Trading”) in Appendix A. There is existing open interest of 264 contracts, and all open interest
holders have consented to the amendment. There is no impact on contract value. The amendment shall become
effective Sunday, December 16, 2012 for trade date Monday, December 17, 2012.
The amendments are reflected in Exhibit 1, with additions underscored and deletions overstruck.
NYMEX business staff responsible for the rule amendment and the Exchange legal department collectively reviewed

public daily information on settlement prices, volume, open interest, and opening and closing ranges for the
futures contract listed above.

Availability of General Information: Pursuant to the Exchange’s obligations under this core principle, the
Exchange published the amendment to the last trading day to the marketplace via Special Executive
Report 6478, dated November 30, 2012.
Pursuant to Section 5c(c) of the Act and CFTC Regulation 40.6 (a), the Exchange hereby certifies that the listing rule
amendment complies with the Act, including regulations under the Act. There were no substantive opposing views to
this proposal.
The Exchange certifies that this submission has been concurrently posted on the Exchange’s website at
