10. Reportable Segment Information
Upon the acquisition of Intersurface Dynamics in the second quarter of 2021 (see Note 2), we evaluated our organizational structure and concluded that we have two reportable segments following the acquisition. Our two reportable segments are as follows:
Semiconductor – 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.
Material and Substrate – We produce consumables and machinery for lapping (fine abrading) and polishing of materials, such as sapphire substrates, optical components, silicon wafers, numerous types of crystal materials, ceramics and metal components. Our Material and Substrate segment includes our former SiC/LED segment in addition to Intersurface Dynamics, as they sell complementary products to a similar market.
Information concerning our reportable segments is as follows, in thousands:
* Non-segment related assets include cash, property, and other assets.
Goodwill and other long-lived assets
We review our long-lived assets, including goodwill, for impairment at least annually in our fourth quarter or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Additional information on impairment testing of long-lived assets, intangible assets and goodwill can be found in Notes 1 and 10 of our Annual Report on Form 10-K for the year ended September 30, 2021.
