Segment Reporting [Abstract] |
Reportable Segments | 10. Reportable Segments In the operation of the business, management, including our Chief Operating Decision Maker (“CODM”), who is also our Chief Executive Officer, reviews certain financial information, including segmented internal profit and loss statements. The primary profitability measure used by the CODM to review segment operating results is net income. The CODM uses net income to allocate resources during our annual planning process and throughout the year, as well as to assess the performance of our segments, primarily by monitoring actual results compared to prior period and expected results. Amtech has two operating segments that are structured around the types of product offerings provided to our customers. In addition, the operating segments may be further distinguished by the Company’s respective brands. These two operating segments comprise our two reportable segments discussed below. Our two reportable segments are as follows: Thermal Processing Solutions – We design, manufacture, sell and service thermal processing equipment and related controls for use by leading semiconductor manufacturers, and in electronics, automotive and other industries. Semiconductor Fabrication Solutions – We produce consumables parts and services, and equipment for producing silicon carbide, silicon and gallium nitride wafers, optical components and a variety of crystalline materials. Information concerning our reportable segments is as follows, in thousands:
