Segment Reporting [Abstract] |
Segment Reporting | Segment Reporting The Company reports its business segments using the “management approach” model for segment reporting. This means that we determine our reportable business segments based on the way the chief operating decision-maker (“CODM”) analyzes business segments within the Company for making operating decisions and assessing financial performance. We report our financial results in the following three segments: (i) Networking, (ii) Materials, and (iii) Lasers. Our CODM receives and reviews financial information based on these three segments. During the first quarter of fiscal 2025 as a result of a new CEO joining the Company in the fourth quarter of fiscal 2024, our CODM implemented changes in the measure he uses to allocate resources and assess performance. Our CODM now evaluates each segment’s performance and allocates resources based on segment revenue and segment profit, instead of operating income, as our CODM believes segment profit is a more comprehensive profitability measure for each operating segment. Segment profit includes operating expenses directly managed by operating segments, including research and development, direct sales, marketing and administrative expenses. Segment profit does not include share-based compensation, acquisition or integration related costs, amortization and impairment of acquisition-related intangible assets, restructuring charges, and certain other charges. Additionally, effective the first quarter of fiscal 2025, we no longer allocate Corporate strategic research and development, strategic marketing and sales expenses and shared general and administrative expenses, as these expenses are not directly attributable to our operating segments. The segments are managed separately due to the market, production requirements and facilities unique to each segment. The accounting policies are consistent across each segment. Effective the first quarter of fiscal 2025, we no longer allocate corporate assets to the segments. Comparative prior period segment information has been recast to conform to the new segment profitability measure. The change in our operating segment measure had no impact on our previously reported consolidated results of operations, financial condition, or cash flows. The following table summarizes selected financial information of our operations by segment and reconciles segment profit to consolidated earnings (loss) before income taxes for the periods presented ($000):
