At the open of RTH, there shall be Price Limits corresponding to a 10.0%, 20.0% and 30% decline below the Reference RTH Price.

The Price Limits shall be calculated at the beginning of each calendar quarter, based upon the average closing price of the Nasdaq 100 Index futures contract whose expiration date matches that of the current primary E–Mini futures contract, during the month prior to the beginning of the quarter (P) and rounded, as follows:

5.0% Price Limit equals One half of the 10% Price Limit rounded down to nearest integral multiple of 1 index point

10.0% Price Limit equals 10% of P rounded down to nearest integral multiple of 10 index points

20.0% Price Limit equals 2 times the 10.0% Price Limit

30.0% Price Limit equals 3 times the 10.0% Price Limit

When the primary futures contract is limit offered at the 10.0% Price Limit, a 10-minute period shall commence. If the primary futures contract is limit offered at the end of the 10-minute period, trading shall terminate for a period of two minutes, after which time the market shall reopen. The next applicable price Limit shall apply to such reopening.

When the primary futures contract is limit offered at the 20.0% Price Limit, a 10-minute period shall commence. If the primary futures contract is limit offered at the end of the 10-minute period, trading shall terminate for a period of two minutes, after which time the market shall reopen. The 30% Price Limit shall apply to such reopening and shall represent the Total Daily Price Limit.

If an NYSE Rule 80B trading halt becomes inapplicable, the corresponding Price Limit shall likewise become inapplicable. E.g., if an NYSE Rule 80B trading halt, triggered by a 10% or a 20% decline in the Dow Jones Industrial Average, has been declared in the primary securities market, and trading in the primary securities market has recommenced, then the 10.0% or 20.0% Price Limits shall become inapplicable, respectively. E.g., when the NYSE Rule 80B 10.0% price limit provisions are suspended after 2:30 p.m. Eastern time, then the 10.0% Price Limit shall become inapplicable. Trading on the E-Mini Nasdaq 100 Index futures contract shall continue and the next applicable Price Limit shall apply.

The Final Settlement Price shall be a Special Opening Quotation of the Nasdaq 100 Index to be determined by the Nasdaq Stock Market Inc. (“Nasdaq”). If the Nasdaq does not open on the day scheduled for the determination of the Final Settlement Price, then the Final Settlement Price shall be the Special Opening Quotation of the first subsequent day on which Nasdaq does open.

The Special Opening Quotation of the Nasdaq 100 Index shall be based on the Nasdaq Official Opening Price (NOOP) of Nasdaq 100 Index stocks.

If a component stock in the index does not trade after 8:30 a.m. and before 3:00 p.m. on the day scheduled for determination of the Final Settlement Price while Nasdaq is open for trading, the price of that stock shall be determined, for the purposes of calculating the Final Settlement Price, based on the closing price of that stock on the preceding trading day. However, if the President of the Exchange or his delegate determines that there is a reasonable likelihood that trading in the stock shall occur shortly, the President or his delegate may instruct that the price of stock shall be based, for the purposes of calculating the Final Settlement Price, on the NOOP of the stock on the next day that it is traded on its primary market. Factors to be considered in determining whether trading in the stock is likely to occur shortly shall include the nature of the event and recent liquidity levels in the affected stock.
