Certain GBP/USD Currency Contracts Settled Using Reuters Data on September 21, 2015
As stated on the Nadex website, if data from the NadexFX currency feed is unavailable, Nadex may obtain market pricing data through another data provider deemed appropriate under the circumstances. Due to the unavailability of the underlying NadexFX data for the spot GBP/USD currency pair, Expiration Values for the September 21, 2015 5 Minute GBP/USD Binary contracts expiring at 6:05pm, 6:10pm, 6:15pm, 6:20pm, 6:25pm, 6:30pm, 6:35pm, and 6:40pm ET were calculated using data obtained from Reuters.
This action was taken in accordance with Rule 7.1, which grants Nadex the authority, in its discretion, to adjust the terms of an outstanding Series to achieve fairness to holders of the affected Contracts and to delay settlement of the Series until the outcome is clear to Nadex as determined by reasonable means when underlying data is unavailable.
Additionally, 5 Minute GBP/USD Binary contracts with expirations at 6:45pm, 6:50pm, 6:15pm, 6:55pm, 7:05pm, 7:10pm, 7:15pm, and 7:20pm ET were not listed. This action was taken pursuant to the authority granted in Rule 12.31(f)(iv)(5) which states that Nadex may, in its discretion, temporarily refrain from listing any 5-Minute Binary contract due to the unavailability of the underlying market upon which the Contract is based, or any other condition Nadex determines may be detrimental to the listing of the Contract. The listing and settlement of the 5-Minute GBP/USD Binary contracts resumed as normal with the listing of the 7:25pm ET expiration contract.
