Aggregate Reserves in Tons
This is the total amount of aggregates the company has available for sale in the future. Aggregates include crushed stone, sand and gravel, rock asphalt, recycled concrete, and other similar materials used in construction.
Since aggregates have quite a low value-to-weight ratio (its incredibly expensive to transport such heavy products) aggregate companies establish localized reserves that store aggregates to be sold in particular local markets. Reserves are a primary factor of ongoing viability for the company, as it determines the amount of products the company has available to sell in the future. The higher the reserves, the longer the company can stay viable even if its production is halted.
