Conflict Minerals Report
For The Year Ended December 31, 2015
This report for the year ended December 31, 2015 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934.
Our due diligence measures have been designed to conform, in all material respects, with the framework in the Organization for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD 2011) (OECD Framework) and related Supplements for gold, tantalum, tin and tungsten (conflict minerals).
Our supply chain is complex and there are multiple tiers between the company and the mines. We rely on our suppliers to provide information on the origin of the conflict minerals contained in components which are included in our products. To identify and assess risk in the supply chain, we engaged those suppliers who provide the substantial majority of our components and whose products we believe are likely to contain conflict minerals. We conducted a survey of these suppliers, which accounted for in excess of 80% of component costs incurred during 2015, to determine whether the necessary conflict minerals in components contained in our products were or were not DRC conflict free (as defined in Item 1.01 of Form SD). The survey requested suppliers to provide the country of origin of any conflict minerals and the facilities used to process these minerals. We received responses from approximately 95% of the suppliers surveyed containing the names and locations of smelters and refiners which process conflict minerals used in components provided by our suppliers. We reviewed and compared the responses with other information in our possession and, where appropriate, made further inquiries of our suppliers. The initial and subsequent responses from suppliers did not contain sufficient information to determine the country of origin of all the conflict minerals in our products.
The smelters and refiners identified by our suppliers are listed in Appendix A below.
Our products for which conflict minerals are necessary to the functionality or production include, but are not limited to, laser ablation products, laser processing system products, microfabrication products, laser component products, FPD repair & failure analysis products, LED wafer scriber products, laser fuse processing products, laser trimming products, vision products, wafer dicing products, wafer mark products, electrical tester products, inspection products, tooling products, pyroflex products and solar market application products. These products are more fully described in our Annual Report, which can be accessed at http://investors.esi.com/.
We expect to take the following steps to mitigate the risk that the necessary conflict minerals in our products do not benefit armed groups in the Democratic Republic of Congo (DRC) or any adjoining country, including:
| • | Attempting to increase the response rate of suppliers and improve the content of the responses. |
| • | Attempting to validate supplier responses using information collected via independent conflict free smelter validation programs such as the EICC/GeSI Conflict Free Smelter Program. |
Based on a “reasonable country of origin inquiry” (RCOI) ESI knows or has reason to believe that a portion of its necessary conflict minerals originated or may have originated in the Democratic Republic of the Congo or an adjoining country (collectively, the “Covered Countries”) and is unable to determine that those necessary conflict minerals did not come from recycled or scrap sources.
