Segment Information

3.** Segment Information

Chief Operating Decision Maker

The Company’s chief operating decision maker ("CODM") is the Chief Executive Officer.

Reportable Segments

We report our results of operations consistent with the manner in which the CODM reviews the business to assess performance and allocate resources. As such, we report our results in a single reporting segment: Electronic Components.

The Electronic Components segment derives revenues from sales to customers of wide range of precision frequency control and spectrum control solutions, including, butnot limited to, the following:

•filters;
•oscillators;
•crystal resonators; and
•integrated microwave assemblies.

Measure of Segment Profit or Loss and Segment Assets

The accounting policies of the Electronic Components segment are the same as those described in Note2 – Summary of Significant Accounting Policies.

The CODM assesses the performance of and decides how to allocate resources to the Electronic Components segment based on Segment gross profit (loss) as well as Net income, which is also reported on the Consolidated Statements of Operations as consolidated Net income. The CODM uses Segment gross profit to evaluate to evaluate the manufacturing costs of the Electronic Components segment’s products and to ensure those products are priced appropriately. The CODM uses Segment net income to evaluate income generated from segment assets in deciding whether to reinvest profits into the Electronic Components segment or into other parts of the entity, such as for capital expenditures or acquisitions. Additionally, the CODM uses net income to monitor budget versus actual results as well as in competitive analysis to Mtron's peers. The budget versus actuals and competitive analysis are used in assessing the performance of the Electronic Components segment.

The measure of segment assets is reported on the Consolidated Balance Sheets as consolidated Total assets.
