Business Segment Information
 
Following the Company's acquisition of BTU, an evaluation was conducted of the Company's organizational structure. Beginning with the second quarter of fiscal 2015, the Company made changes to its reportable segments. Prior period amounts have been revised to conform to the current period segment reporting structure. The Company’s three reportable segments are as follows:

Solar - In the Company’s Solar segment, we are a leading supplier of thermal processing systems, including related automation, parts and services, to the solar/photovoltaic industry and also offer PECVD (plasma-enhanced chemical vapor deposition) equipment to the global solar market.

Semiconductor - In the Company’s Semiconductor segment, 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.

Polishing - In the Company's Polishing segment, the Company produces 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.

On December 24, 2014, the Company acquired a 51% controlling interest in SoLayTec, and on January 30, 2015, the Company completed its acquisition of BTU. Beginning in the second quarter of 2015, SoLayTec’s business is included in the results for the solar segment, and BTU’s business is included in the results for the semiconductor segment. See Note 10, “Acquisitions”, for additional information with respect to the Company’s recent acquisitions.
