Revenue from Contracts with Customers [Abstract]

Revenue from Contracts with Customers

Note 2.  Revenue from Contracts with Customers

On a regular basis, the Company reviews its segments and the approach used by the chief operating decision maker to assess performance and allocate resources. Accordingly, in the first quarter of 2021, the Company reorganized the management structure for its Energy Services and Performance Materials operating segments to support MTI's key growth initiatives, more closely align complementary technologies, processes and capabilities, and better reflect the way performance is evaluated and resources are allocated.  As a result, Energy Services, was combined into the Environmental Products product line within the Performance Materials operating segment.  Restated financial results, by product line, of this operating segment for each quarter of 2020 to conform to the current management structure are presented in Note 15.

The following table disaggregates our revenue by major source (product line) for the three and nine-month periods ended October 3, 2021 and September 27, 2020:
