Why are some issues excluded from the circulation certificate?
The ABC figure is the average circulation over a given period. An issue may be affected adversely, which could then distort the typical average. Publishers can exclude issues from the average due to bank holidays or where they can demonstrate that a material loss of circulation has occurred. Material means a loss of at least 10% of the UK & RoI circulation less any multiple copy sales e.g. public holidays, industrial action, computer failure, or machinery breakdown which prevents the timely distribution of the publication. Examples which are not accepted by ABC as being beyond the publisher’s control include editorial content, poor sales days, and minor delays in distribution.
