Of course, it's possible that the same horse could be entered in another handicap before the team of handicappers at the British Horseracing Authority (BHA) has had the opportunity to revise its handicap rating. In that case, the horse in question will carry a penalty, say 6lb, which is denoted by '6ex' immediately to the right of its allotted weight on the racecard. In some cases, penalties may also be incurred by horses that have won a race, or races, above a certain 'penalty value' in a specified period.
A similar situation exists in Listed and Pattern Races, insofar that a horse that has won in a higher grade within a specified period, or at any time, may be penalised if it races in a lower grade. In a Group 3 race, for example, horses that have already won at that level may be penalised 3lb as a matter of course, while horses that have previously won at Group 1 or Group 2 level may be penalised 5lb.
