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.
