9. | Business Segments
The Building Material business contains two reportable segments: the East Group and the West Group. The Company also has a Magnesia Specialties segment. The Company’s evaluation of performance and allocation of resources are based primarily on earnings from operations. Consolidated earnings from operations include total revenues less cost of revenues; selling, general and administrative expenses; acquisition-related expenses; other operating income and expenses, net; and exclude interest expense; other nonoperating income and expenses, net; and income taxes. Corporate loss from operations primarily includes depreciation; expenses for corporate administrative functions; acquisition-related expenses; and other nonrecurring income and expenses excluded from the Company’s evaluation of business segment performance and resource allocation. All long-term debt and related interest expense are held at Corporate. The following table displays selected financial data for the Company’s reportable segments. Total revenues, as presented on the consolidated statements of earnings and comprehensive earnings, exclude intersegment revenues, which represent sales from one segment to another segment and are eliminated in consolidation.
