Producer gross margins2.5.1. Calculating gross marginsThe calculations used in the construction of gross margin are reviewed below (as for variable andfixed costs, these data were subsequently converted into kg terms at 16 eggs per kg):Egg revenue: this was variously presented in the data obtained as revenue per dozen, perkilogram of egg or per egg. Where data was in weight terms this was adjusted to per egg termsusing national egg weights from the International Egg Commission. Estimating revenue from eggsales is not as straightforward as it might sound. In some cases the figures provided werecorrected using data derived from the source to account for the different prices achieved by firstand second quality eggs. In others this calculation was not performed because of the variabilityof prices between producers in a Member State resulting from different quality bonuses and thevariation in the proportion of second quality eggs.Spent hen revenue: whether positive or negative this figure was divided by the number of eggsproduced over the laying cycle and multiplied by 16.Total output: the sum of the above. Total variable cost: this is the sum of the variable costs outlined in Section 2.4.Gross margin: total output less total variable cost.46
