N2EX re-calculated the Auction Market price for Sunday 11 November 2012, due to an error in the block order acceptance process leading to a large number of paradoxically accepted block orders in the market.
The decision to re-calculate the Auction price was taken according to the N2EX rulebook Appendix 2b, Auction Market Regulations paragraph 6.1.5.
The recalculated prices were published to the market at 10:52 GMT.
Subsequently, the auction with delivery for Monday the 12th was delayed.
We apologize for any inconvenience this has caused to members.
