Segment Reporting [Abstract] |
Segments | 10. Segments The Building Materials business is comprised of four divisions that represent individual operating segments. These operating segments are consolidated into two reportable segments, the East Group and the West Group, for financial reporting purposes, as they meet the aggregation criteria. The Specialties business represents an individual operating and reportable segment. The Company’s Chief Operating Decision Maker (CODM) is the Chair, President and Chief Executive Officer. The CODM reviews results by reportable segment on a quarterly basis and allocates resources to achieve the Company’s strategic objectives based on an evaluation of each reportable segment’s performance. This evaluation is largely based on segment earnings from operations, as management believes this is the best metric of segment profitability and operating performance. Segment earnings from operations is also a measure in the determination of incentive compensation targets and awards. Segment earnings from operations includes revenues less cost of revenues; selling, general and administrative expenses; other operating income and expenses, net; and exclude interest income and expense; other nonoperating income and expenses, net; and income tax expense. The significant expense categories shown below align with the segment-level information regularly provided to the CODM. Other costs of revenues for each reportable segment mainly include repairs and maintenance, contract services, supplies and royalties. Corporate loss from operations primarily includes depreciation and amortization; expenses for corporate administrative functions; acquisition, divestiture and integration expenses; and other nonrecurring income and expenses not attributable to operations of the Company's operating segments. Earnings from operations for the West Group for the nine months ended September 30, 2024 included a $1.3 billion gain and $16 million in transaction expenses on the divestiture of the South Texas cement business and certain of its related ready mixed concrete operations (see Note 2) and a noncash asset and portfolio rationalization charge of $50 million (see Note 13). The following tables display selected financial data for the Company’s reportable segments. Revenues, as presented on the consolidated statements of earnings and comprehensive earnings, reflect the elimination of intersegment revenues, which represent sales from one segment to another segment and are immaterial. Revenues and earnings (loss) from operations reflect continuing operations only. Income tax expense is not allocated to the Company's reportable segments.
