| Segment Reporting |
Segment Reporting The Company has the following reportable segments: Performance Materials, Electronic Materials, Precision Optics, and Other. The Company’s reportable segments represent components of the Company for which separate financial information is available that is utilized on a regular basis by the Chief Executive Officer, the Company's Chief Operating Decision Maker (CODM), in determining how to allocate the Company’s resources and evaluate performance. Performance Materials provides advanced engineered solutions comprised of beryllium and non-beryllium containing alloy systems and custom engineered parts in strip, bulk, rod, plate, bar, tube, and other customized shapes. Electronic Materials produces advanced chemicals, microelectric packaging, precious metal, non-precious metal, and specialty metal products, including vapor deposition targets, frame lid assemblies, clad and precious metal preforms and high temperature braze materials. Precision Optics produces thin film coatings, optical filter materials, sputter-coated, and precision-converted thin film materials. The Other reportable segment includes unallocated corporate costs and assets. The primary measures used by management to allocate resources and measure the financial performance of each segment are earnings before interest and taxes (EBIT) and earnings before interest, taxes, depreciation and amortization (EBITDA). Segment EBIT is the measure of segment profit or loss that is most consistent with the measurement principles used in measuring the corresponding amounts in the Company's consolidated financial statements. The CODM evaluates segment EBIT in assessing the profitability and operating performance of each reportable segment and uses segment EBITDA to evaluate operating performance excluding the effects of depreciation and amortization and to compare performance among periods. The Company believes the use of EBITDA assists in understanding the ongoing operating performance by presenting comparable financial results between periods and believes that by removing the impact of depreciation and amortization and amounts spent on interest and taxes that may vary from year to year, EBITDA provides a performance measure that reflects the impact to operations from trends in changes in net sales, gross margin and operating expenses, providing a perspective not immediately apparent from net income (loss) and operating income (loss). The adjustments the Company makes to derive the financial measure of EBITDA excludes items which may cause short-term fluctuations in net income (loss) and operating income (loss) and which the Company does not consider to be the fundamental attributes or primary drivers of its business. EBITDA provides disclosure on the same basis as that used by the CODM to evaluate financial performance on a reportable segment basis.
