Segments and Related Information

Segment Discussion

MasTec presents its continuing operations under five reportable segments: (1) Communications; (2) Oil and Gas; (3) Electrical Transmission; (4) Power Generation and Industrial and (5) Other. This structure is generally focused on broad end-user markets for MasTec's labor-based construction services. All five reportable segments derive their revenues from the engineering, installation and maintenance of infrastructure, primarily in North America.

The Communications segment performs engineering, construction and maintenance of communications infrastructure primarily related to wireless and wireline communications and install to the home, and to a lesser extent, infrastructure for electrical utilities. MasTec performs engineering, construction and maintenance services on oil and natural gas pipelines and processing facilities for the energy and utilities industries through its Oil and Gas segment. The Electrical Transmission segment primarily serves the energy and utility industries through the engineering, construction and maintenance of electrical transmission lines and substations. The Power Generation and Industrial segment primarily serves the energy and utility end markets and other end markets through the installation and construction of conventional and renewable power plants, related electrical transmission infrastructure, ethanol facilities and various types of industrial infrastructure. The Other segment primarily includes small business units that perform construction services for a variety of end markets in Mexico and elsewhere internationally.

The accounting policies of the reportable segments are the same as those described in Note 1 - Business, Basis of Presentation and Significant Accounting Policies. Intercompany revenues and costs among the reportable segments are de minimus and accounted for as if the sales were to third parties because these items are based on negotiated fees between the segments involved. All intercompany transactions and balances are eliminated in consolidation. Intercompany revenues and costs between entities within a reportable segment are eliminated to arrive at segment totals. Eliminations between segments are separately presented. Corporate results include amounts related to Corporate functions such as administrative costs, professional fees, and acquisition costs. Segment results include certain allocations of centralized costs such as general liability, medical and workers' compensation insurance and certain information technology costs. Income tax expense is managed by Corporate on a consolidated basis and is not allocated to the reportable segments.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is the measure of profitability used by management to manage its segments and, accordingly, in its segment reporting. As appropriate, the Company supplements the reporting of consolidated financial information determined in accordance with U.S. GAAP with certain non-U.S. GAAP financial measures, including EBITDA. The Company believes these non-U.S. GAAP measures provide meaningful information that helps investors understand the Company's financial results and assess its prospects for future performance. The Company uses EBITDA to evaluate its performance, both internally and versus that of its peers, because it excludes certain items that may not be indicative of the Company's reportable segment results, as well as items that can vary widely across different industries or among companies within the same industry. Segment EBITDA is calculated in a manner consistent with consolidated EBITDA. Corporate EBITDA in 2011 includes a $29 million gain from remeasurement of our equity interests in EC Source upon the Company's acquisition of the remaining equity interests in EC Source.
