[1] Americas Materials and Europe Materials both operate vertically integrated businesses, which are founded in resource-backed cement and aggregates assets and which support the manufacture and supply of aggregates, asphalt, cement, readymixed and precast concrete and landscaping products. Accordingly, for the purpose of disaggregation of revenue we have included certain products together, as this is how management reviews and evaluates this business line.
