NYMEX Rule 9.26, All Month/Any One Month Position Accountability

(A) Any person, as defined in Rule 1.26, who owns or controls positions in excess of the levels cited in Sections (C) and (D) of this Rule shall be subject to the following provisions pursuant to position accountability levels:

(1) promptly supply to the Exchange such information as the Exchange may request pertaining to the nature and size of the position, the trading strategy employed with respect to the position, and the position owner's or controller's hedging requirements, provided, however, that if the position owner or controller fails to supply such information as and when requested, the President or his designee may order the reduction of such position;

(2) agree, upon request by the President or his designee, not to increase the position owned or controlled as of the time the request was received; and

(3) agree to comply with any prospective limit prescribed by the President or his designee which exceeds the size of the position owned or controlled.

(B) For the purposes of this Rule 9.26, the futures-equivalent of an option contract and spread option contract is the previous day's NYMEX Risk Factor for that option. Further, long calls, short puts and long futures are on the same side of the market; short calls, long puts and short futures are on the same side of the market.

With respect to crack spread option contracts, a call option is the equivalent of a long product futures contract and a short crude oil futures contract; a put option is the equivalent of a short product futures contract and a long crude oil futures contract. Therefore, long crack spread option calls and short crack spread option puts are on the same side of the market; short crack spread option calls and long crack spread option puts are on the same side of the market.

With respect to calendar spread option contracts, a call option is the equivalent of a long futures contract in the first underlying futures in the spread and a short futures contract in the second underlying futures in the spread; a put option is the equivalent of a short futures contract in the first underlying futures in the spread and a long futures contract in the second underlying futures in the spread.

(C) For purposes of this rule, a Crude Oil e-miNY(sm) contract shall be deemed equivalent to .50 of a Crude Oil light Sweet future cited in (i)(a) below. A NYMEX Natural Gas miNY™ Futures Contract e-miNY(sm) shall be deemed equivalent to .50 .25 of a Natural Gas future cited in (x) below.

(D) Except as provided in Rule 9.27, the any one month/all month position accountability levels for each futures contract traded on the Exchange are:

(Remainder of Rule 9.26 is unchanged.)

(B) The expiration position limits for energy contracts set forth below are effective on the open of trading of the last three trading days of the futures contract.

A NYMEX Natural Gas miNY™ Futures Contract e-miNY(sm) shall be deemed equivalent to .50 .25 of a Natural Gas future cited in (x) below.
