Nadex Amends its Fee Schedule, Adds Daily Spreads, and Clarifies/Amends Expiration Value

Pursuant to Section 5c(c)(1) of the Commodity Exchange Act, and Commission Regulation §40.6(a), Nadex amends its Rules to add daily spread contracts in the Metal, Energy, and Index Variable Payout Contracts (excluding the Japan 225 and Korea 200 Contracts). These additions are set forth in Rules 12.2, 12.4, 12.6, 12.8, 12.10, 12.48, 12.50, 12.58, 12.60, 12.62, and 12.64. Nadex also clarifies the Expiration Value language in the Commodity, Currency, and Index Contracts (Rules 12.2-12.15, 12.26-12.41, 12.48-12.51, and 12.54-12.63). Except for the Wall Street 30 Variable Payout and Binary Contracts (Rules 12.64 and 12.65), Expiration Values will now be rounded to one decimal point past the precision of the underlying market. Additionally, the terms "Treasurer" and "Authorized Trader", found in Rules 2.3 and 3.4 respectively, were replaced with "Chief Financial Officer" and "employee or associated person". Rule amendments are effective as of July 18, 2011.

Lastly, this certification amends the Nadex Fee Schedule for Direct and FCM Members. Pursuant to Nadex Rule 3.8(e), Nadex is proving 30-days' notice for the amendments to its Fee Schedule. Accordingly, Fee Schedule amendments and additions will be effective August 18, 2011. Existing members will remain on the current Fee Schedule, but may opt for the new Fee Schedule by notifying the Exchange. Existing Members will be emailed instructions for requesting the Fee Schedule change prior to the effective date of the new Fee Schedule. All new customers registering with the Exchange on or after August 18, 2011 will be subject to the new Fee Schedule.
