|Segment Reporting [Abstract]
|Segment Information We operate in four reportable segments based on four geographic countries or regions in which we operate: (i) United States and Latin America ("US-LAM"), (ii) Canada, (iii) Europe, Middle East and Africa ("EMEA") and (iv) Asia-Pacific ("APAC"). Within our four reportable segments, our core products and services are focused on thermal solutions primarily related to the electrical heat tracing industry. Each of our reportable segments serves a similar class of customers, including engineering, procurement and construction companies, international and regional oil and gas companies, commercial sub-contractors, electrical component distributors and direct sales to existing plant or industrial applications. Profitability within our segments is measured by operating income. Profitability can vary in each of our reportable segments based on the competitive environment within the region, the level of corporate overhead, such as the salaries of our senior executives, and the level of
research and development and marketing activities in the region, as well as the mix of products and services. Since March 2015, we acquired THS, Unitemp Close Corporation ("Unitemp"), Industrial Process Insulators, Inc. ("IPI") and TPS. THS (formerly known as CCI Thermal Technologies Inc.) develops and produces advanced industrial heating and filtration solutions for industrial and hazardous area applications that closely align with Thermon's core business and serves similar end markets in North America. As such, we have elected to report THS's operations through our US-LAM and Canada reportable segments. Both Unitemp and IPI offer thermal solutions and have been included in our EMEA and US-LAM reportable segments, respectively. TPS provides temporary power products that differ from our core thermal solutions business. As we anticipate that our full year operating results from TPS will comprise less than 10% of our total sales and operating income, TPS has been aggregated in our Canada segment. For purposes of this note, revenue is attributed to individual countries or regions on the basis of the physical location and jurisdiction of organization of the subsidiary that invoices the material and services.
Total sales to external customers, inter-segment sales, depreciation expense, amortization expense, income from operations, property, plant and equipment, net and total assets for each of our four reportable segments are as follows:
Capital expenditures by geographic area were as follows:
