Nadex Closes Certain FTSE 100 and Germany 30 Daily and Intarday Contracts and Cancels Certain Open Positions

Pursuant to Section 5c(c)(1) of the Commodity Exchange Act, and Commission Regulation §40.6(a), Nadex submitted to the Commission notice of an emergency action to close certain daily and intraday markets in its FTSE 100® and Germany 30 Binary Contracts and Spread Contracts. This action was deemed necessary because the market maker for the FTSE 100 and Germany 30 Daily and Intraday Binary and Spread Contracts was unable to make a continuous bid-offer in those markets due to a lack of activity in the relevant underlying markets. As part of this emergency action, Nadex has cancelled the trades comprising the open interest in the affected contracts at the time of the action.

Nadex expects this action to continue through trade date December 20, 2012 and plans to resume its regular listing schedule for these contracts on December 21, 2012.
