The Unpriced Accepted Bids Volume is defined as the sum of the volumes of all Bids accepted for the period which are not De Minimis Acceptance volumes and not Arbitrage Accepted Bids which have been Classified as Second Stage Flagged (i.e. which are eligible to be re-priced).

It should be noted that a consequence of this definition is that adding together the Priced and Unpriced Accepted Bids Volumes, PABV and UABV, does not necessarily give the total volume of Bids accepted for the Period, because any De Minimis or Arbitrage Accepted Bid volumes will not be included.
