(8)The data required for the calculation of notification thresholds for net short positions relating to issued sovereign debt will not be available at the date of entry into force of this Regulation. Therefore the two criteria used to set the initial notification thresholds at the date of publication should be firstly the total amount of outstanding issued sovereign debt of the sovereign issuer and secondly the existence of a liquid futures market for that sovereign debt. Revised thresholds should be adopted when the relevant data on all the criteria is available.
