Conflict Minerals Report
IPG Photonics Corporation (the "Company") manufactures certain products, described more fully below, that contain "Conflict Minerals" within the meaning of Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Act"). For purposes of the Act, "Conflict Minerals" are currently defined as cassiterite, columbite-tantalite, gold, wolframite and their derivatives, which are limited to tin, tantalum, tungsten and gold. Recognizing that some Conflict Minerals that are sourced from the Democratic Republic of the Congo or its adjoining countries (the "DRC Region") are used to support the conflict and humanitarian crisis in the DRC Region, and in compliance with the Act's requirements, the Company sought to determine the origins of its Conflict Minerals.
| |
| 2. | Scope of the Company's Conflict Minerals Report |
The information contained in this report includes the activities of the Company's consolidated subsidiaries. Because the Company was unable to determine the source of all of its Conflict Minerals, and pursuant to the guidance issued by Securities and Exchange Commission ("SEC"), this report is not subject to an independent private sector audit.
The Company manufactures high-performance optical fiber-based lasers and amplifiers, packaged diodes, direct diode lasers, laser systems, communications systems and materials processing laser systems that utilize its optical-based products. The Company manufactures diode-pumped fiber lasers and fiber amplifiers for a variety of materials processing, micromachining, telecommunications, medical and other advanced applications. Such products contain parts or components that contain Conflict Minerals that are necessary for the functionality or production of these products. Therefore, the Company's products are subject to the reporting obligations of Rule 13p-1 under the Securities Exchange Act, as amended (the "1934 Act").
| |
| 4. | Reasonable Country of Origin Inquiry |
The Company does not have direct relationships with smelters or refiners ("SORs") but became familiar with the Conflict Free Smelter Initiative (the "CFSI"), an initiative which supports the validation and certification of smelters as "conflict free." As recognized by the CFSI in its white paper "Reasonable Practices to Identify Sources of Conflict Minerals: Practical Guidance for Downstream Companies," the Company, as a "downstream" company, possesses no independent means of determining the source and origin of conflict minerals ores processed by smelters or refiners. The Company does not purchase raw ore or unrefined Conflict Minerals and has no direct suppliers in the DRC Region. The Company purchases materials used in its products from a large network of suppliers, and some of those materials contain Conflict Minerals. The Company relies on its suppliers to assist in its efforts to determine the origins of the Conflict Minerals contained in the materials they supply to the Company.
In preparation for conducting its Reasonable Country of Origin Inquiry ("RCOI"), an inquiry regarding the origin of conflict minerals designed to determine the origination of minerals used by the Company's suppliers or if such minerals are from recycled or scrap sources, the Company identified the vendors that supply the Company with materials that are incorporated into the Company's products. The Company then conducted a RCOI of its vendors concerning the origins of its Conflict Minerals. Through mail and email communications to these vendors, the Company asked its vendors to complete an online survey based on the questions contained in the Electronic Industry Citizenship Coalition® and The Global e-Sustainability Initiative ("EICC-GeSI") template. This template is a standard reporting template for companies to use to facilitate disclosure and communication of information regarding suppliers that provide materials to a company's supply chain. The Company's online survey provided its vendors with the ability to elaborate on their answers to questions, as well as the ability to attach documents such as the EICC-GeSI reporting template or conflict minerals statements or policies.
In response to the Company's RCOI, many suppliers responded that they were in the process of surveying their own suppliers or were uncertain about the origins of their Conflict Minerals. Accordingly, the Company was unable to determine the source of all of its Conflict Minerals and proceeded with further due diligence measures about the origins of its Conflict Minerals. There is significant overlap between the Company's RCOI efforts and its due diligence measures described below.
5. Design of the Company's Due Diligence and Description of Due Diligence Process
The Company's Conflict Minerals compliance framework and due diligence were based on the Organisation for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Second Edition, and related Supplements on Tin, Tantalum and Tungsten and on Gold (together, the "Guidance"), with a particular focus on the recommendations issued for downstream companies. Companies must exercise due diligence on the source and chain of custody of the conflict minerals contained in their products. Such due diligence measures must conform to a nationally or internationally recognized due diligence framework, such as the Guidance. As recognized by the CFSI in "Reasonable Practices to identify Sources of Conflict Minerals: Practical Guidance for Downstream Companies", downstream companies with no direct relationships with an SOR, like the Company, possess no independent means of determining the source and origin of conflict minerals ores processed by the SORs. However, to meet its obligations under Rule 13p-1 under the 1934 Act, the Company implemented a due diligence program to identify and trace the Conflict Minerals in its supply chain based upon the Guidance. As discussed further below, the Company implemented the following as its diligence procedures:
| |
| 1. | Adopted a Conflict Minerals Policy; |
| |
| 2. | Established a cross-departmental team to execute and monitor the Conflict Minerals Policy; |
| |
| 3. | Established a process to solicit information regarding Conflict Minerals from the Company’s suppliers; |
| |
| 4. | Reviewed information received from suppliers or followed up with suppliers who did not respond to requests for information; and |
| |
| 5. | Strengthened its engagement with its suppliers through contract language and direct communications. |
5.1 Due Diligence Measures Consistent With Step 1 of The Guidance
The Company established a management system to support the Company's compliance obligations. The Company's management system included the adoption of the IPG Photonics Corporation Conflict Minerals Policy (the "Policy"), which is published on the Company’s publicly available website at http://www.ipgphotonics.com/conflict_minerals.htm. The Company also adopted a Conflict Minerals Compliance Procedure (the "Procedure"), which established cross-departmental teams consisting of the purchasing, finance, legal, information technology and product/manufacturing departments, to execute and monitor the effectiveness of the Policy and the Procedure. The Procedure provides a process to request information from the Company's first-tier suppliers concerning the origins of their materials and the identity of the SORs in their own supply chains. The Company also strengthened its engagement with its suppliers by including a new provision in IPG Photonics' Terms and Conditions of Purchase, which is intended to govern the terms of a substantial portion of the Company's relationships with its suppliers. This provision requires the Company's first-tier suppliers to be in compliance with the Act and to provide disclosure to the Company concerning the sources of their Conflict Minerals. The Procedure also implements a new IPG Photonics Vendor Sourcing Information Form for Conflict Minerals and Component Vendors, which requests new suppliers of the Company to provide information concerning the sourcing of its Conflict Minerals.
5.2 Due Diligence Measures Consistent With Step 2 of the Guidance
Because of the Company's size, the variety and complexity of its products, and the changing nature of its extensive supply chain, the Company was unable to identify with certainty the upstream suppliers in its direct suppliers' supply chains. The Company has relied on the responses it has received from its direct suppliers concerning the origin of the Conflict Minerals contained in the parts and components supplied to the Company, including the information provided from upstream suppliers of its direct suppliers. The Company conducted the survey of its vendors to attempt to identify the SORs in its supply chain. The Company issued follow-up requests for information to direct suppliers who did not respond to the survey. The Company also reviewed information collected from vendors and contacted direct suppliers that it identified whose responses to its survey were incomplete or potentially inaccurate to seek additional clarifying information. The Company documented and reviewed the country of origin information for the SORs identified by its vendors in response to the survey.
5.3 Due Diligence Measures Consistent With Step 3 of the Guidance
As recognized by the CFSI, the Company, as a downstream company with no direct relationship to SORs, can only "mitigate risk through working with their direct suppliers individually or collectively to identify SORs." Accordingly, the Company sought to increase its visibility into its supply chain by contacting some of its larger suppliers who had not yet identified the SORs in their supply chain and requested that they provide this information. The Company reviewed the geographical locations of the SORs identified by its suppliers to determine if these SORs appeared to be
in "red flag" locations, such as the DRC Region. The Company's review of the SORs identified by its suppliers did not reveal any SORs in the DRC Region.
5.4 Due Diligence Measures Consistent With Step 4 of the Guidance
The Company supported the CFSI by adopting the questions used in the EICC-GeSI template as a basis for its survey and requesting its direct suppliers to provide responses to the questions in the survey.
5.5 Due Diligence Measures Consistent With Step 5 of the Guidance
The Company posted the Policy on its publicly available website at http://www.ipgphotonics.com/conflict_minerals.htm and prepared this Conflict Minerals Report as its annual report on the Company's Conflict Minerals Due Diligence.
| |
| 6. | Future Due Diligence Measures |
During the reporting period for the calendar year ending December 31, 2014 the Company plans to take the following actions to increase our visibility into the origins of its Conflict Minerals:
| |
| 1. | Adopt the EICC-GeSI template to better facilitate the assimilation of the information the Company receives from its direct suppliers and to help facilitate the collection of information from upstream suppliers of its direct suppliers; |
| |
| 2. | Seek to increase the response rate from its direct suppliers; and |
| |
| 3. | Evaluate the services of third-party vendors to assist the Company in the collection and assimilation of the sourcing information received from its direct suppliers. |
| |
| 7. | SORs and Countries of Origin of the Company's Conflict Minerals |
Based on the information provided by the Company’s suppliers and the Company's own due diligence to identify known SORs, the Company believes that the facilities used to process the Conflict Minerals in the Company's products include the SORs listed below. Because many of the Company's direct suppliers reported their information to it on a "company" level rather than "product" level, the Company cannot know with certainty whether any of the Company's products contained any Conflict Minerals from any particular country or SOR identified to it. Also, because the Company did not receive responses from all of its suppliers of Conflict Minerals, the Company does not know the origins of all of the Conflict Minerals in its products. Because the Company does not know the origins of all its Conflict Minerals, it cannot conclude that its products do not contain Conflict Minerals originating from the DRC Region.
