Revenues And Gross Profit [Abstract] |
Total Revenues and Gross Profit (Loss) by Product Line | The following tables, which are reconciled to consolidated amounts, provide revenues and gross profit (loss) 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 cement and ready mixed concrete and asphalt and paving product lines. Effective January 1, 2024, the Company combined the cement and ready mixed concrete product lines. This change was driven by the reduced significance of each of these product lines relative to the Building Materials business and consolidated operating results from recent divestitures. Additionally, there is a significant relationship between these product lines, as the ready mixed concrete product line is a significant customer of the cement product line. Revenues and gross profit (loss) reflect continuing operations only.
