Note Q: Revenues and Gross Profit
The following tables, which are reconciled to consolidated amounts, provide total revenues and gross profit by line of business:
Building Materials (further divided by product line) and Magnesia Specialties. Interproduct revenues represent sales from the
aggregates product line to the ready mixed concrete and asphalt and paving product lines and sales from the cement product
line to the ready mixed concrete product line. The Company’s two cold mix asphalt plants have been reclassified from the
asphalt and paving product line to the aggregates product line. These operations did not represent a material amount of
product revenues and gross profit. Prior year information has been reclassified to conform to the presentation of the
Company’s current reportable product lines.
