Sevcon, Inc.

Conflict Minerals Report


For the reporting period from January 1, 2016 to December 31, 2016




This Conflict Minerals Report of Sevcon, Inc. has been prepared pursuant to SEC Rule 13p-1 and Form SD (the “Rule”) for the reporting period January 1, 2016 to December 31, 2016.


The Rule requires disclosure of certain information when a company manufactures or contracts to manufacture products for which the minerals specified in the Rule are necessary to the functionality or production of those products. The specified minerals, which are collectively referred to in this Report as the “subject minerals,” are gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives, which are limited to tantalum, tin and tungsten. The “Covered Countries” for the purposes of the Rule and this Report are the Democratic Republic of the Congo, the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola. As described in this Report, the Company manufactures, or contracts to manufacture, products for which those subject minerals are necessary to the functionality or production.


As a producer of electronic equipment, Sevcon uses a supply base consisting mostly of electronic component manufacturers, distributors and assemblers. Therefore, the facilities used to process the necessary subject minerals in those products, and the country of origin of those subject minerals in those products are several steps down the global electronics supply chain.


The term “conflict-free” is used in this report to denote products, parts or materials where the subject minerals and their deritivite metals are from smelters or refiners verified as complying with the Conflict-Free Sourcing Initiative’s Conflict-Free Smelter Program (the “CFSP”) or an equivalent third-party audit program.




The products manufactured or contracted to be manufactured by Sevcon in calendar year 2016 were –


1.Motor controllers for electric and hybrid vehicles
2.Static and on-board battery chargers for electric and hybrid vehicles
3.DC/DC convertors for electric and hybrid vehicles
4.Other drivetrain system components for electric and hybrid vehicles
5.Industrial/rail/aerospace/automotive Capacitors


Sevcon Conflict Minerals Program and Due Diligence


Sevcon has:


1. Established strong company management systems, by having:
  a. Established a policy to work towards eliminating conflict minerals from its supply chain, and has informed all suppliers of the objectives and reporting requirements. The policy is publicly available at www.sevcon.com/about/quality-environment.
  b. Allocated internal management resource and responsibility for supplier chain due diligence.
  c. Established a system of controls and transparency over the mineral supply chain. The details of this are described below.
  d. Strengthened company engagement with suppliers:


·All components specified by Sevcon and consumed during calendar year 2016 have been identified and traced to the manufacturer.
·All manufacturers have been contacted, in order to trace subject mineral sources.
·Data has been requested using the CFSI template, to ensure compliant smelters are identified.


·The responses have been analyzed, to confirm whether compliance has been achieved (i.e. all smelters declared, and included on the CFSI compliant smelters lists).
·Where new supplier contracts are drafted, conflict minerals objectives and reporting requirements are being included.


  e. Made available the company Environmental Corrective and Preventive Action Procedure available for investigation of any risks relating to Conflict Minerals, with input to the EICC® GeSI program where appropriate.


2. Identified risk in the supply chain, and assessed the adverse impact of those risks.
3. Designed and implemented a strategy to respond to identified risks:


·Working with the suppliers to help them fully understand Sevcon’s requirements.
·Advising on the EICC GeSI Initiative, and the reporting requirements.
·Contacting component manufacturers directly to improve the reporting process.
·Advising of Sevcon’s intention to move away from non-reporting or non-compliant suppliers.
·As a final step, terminating our relationship with non-reporting and non-compliant suppliers.


4. Utilized the EICC GeSI reporting program to analyse the responses of its manufacturers and suppliers.
5. Reported the results of our supply chain due diligence publicly in Form SD as well as internally to senior management.


We conducted a survey of our manufacturing partners and their component suppliers using the template developed jointly by the companies of Electronic Industry Citizenship Coalition (EICC) and The Global e-Sustainability Initiative (GeSI), known as the CFSI Reporting Template (the “Template”). The Template was developed to facilitate disclosure and communication of information regarding smelters that provide material to a company’s supply chain. It includes questions regarding a company’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters the company and its suppliers use. In addition, the template contains questions about the origin of conflict minerals included in their products, as well as supplier due diligence.


Of the manufacturers within the scope of our RCOI, 52% confirmed as not supplying parts containing the subject minerals or using those minerals in their production process. Of the remaining manufacturers/suppliers, 81% responded, and 74% submitted responses in the appropriate EICC GeSI format. Of the responding suppliers, 65% were able to confirm that all of their supplying conflict minerals smelters were listed as compliant on the CFSI lists.


The due diligence methodology applied by Sevcon is based in all material aspects on the OECD “Five-Step Framework for Risk-Based Due Diligence in the Mineral Supply Chain,” including the relevant mineral specific supplements.


Our efforts to determine the mine or location of origin of the necessary conflict minerals in our products with the greatest possible specificity consisted of the due diligence measures described in this conflict minerals report. In particular, because independent third party audit programs validate whether sufficient evidence exists regarding country, mine and/or location of origin of the subject minerals that the audited smelter or refiner facilities have processed, we relied on the information made available by such programs for the smelters and refiners in our supply chain.




We were unable to ascertain the country of origin and/or chain of custody of all necessary subject minerals processed by the facilities that contributed to our products because, for this reporting period, (1) certain smelter and refiner facilities had not yet received a “conflict free” designation from an independent third party audit program, and (2) some manufacturers and their materials suppliers did not respond to our requests for country of origin or chain of custody information.


With respect to the products on which Sevcon exercised due diligence, Annex I lists the facilities which, to the extent known, processed the necessary subject minerals in our products. Annex II summarises the countries for those facilities. Annex III shows the number of smelters which are conflict free as determined by the Conflict-Free Smelter Program (CFSP), and those which are in their audit program with the aim of achieving compliance.




Our investigations have found two smelters in our supply chain from the covered countries –

1.Phoenix Metal Ltd. of Kigali, Rwanda, supplying tin.
2.Universal Precious Metals Refining of Lusaka, Zambia, supplying gold.

Both companies have registered to the CFSI program, but are not in the current compliant or active list. Sevcon is working with the relevant suppliers to ensure that these smelters progress towards certification. If they do not make satisfactory progress, we currently expect they will be removed from the supply chain.


Continuous Improvement Strategy


In order to improve from the above initial results and to mitigate the risk that our necessary conflict minerals will benefit armed groups, Sevcon is taking the following actions:


  a. Working with the suppliers, sub-suppliers and manufacturers to engage with the smelter to enroll in the EICC GeSI Conflict Free Smelters program;
  b. Failing action a, working with the supplier and sub-supplier to select an alternative conflict minerals supplier with supplying smelters participating in the EICC GeSI Conflict Free Smelters program;
  c. Failing action b, selecting an alternative supplier or sub-supplier who can offer conflict-free materials with supplying smelters participating in the EICC GeSI Conflict Free Smelters program.
  d. Monitoring progress towards conflict-free status, by reporting trends publicly and within Sevcon and its supplier base.


Continuous Improvement Results


The table below demonstrates the improvement in reporting and compliance achieved from 2013 to 2016 (reporting periods).


Reporting period 2013 2014 2015 2016 Improvement From 2015
Response level 44% 74% 81% 81% 0%
EICC GeSI format 54% 67% 76% 74% -2%
Compliant response 0% 45% 47% 65% +18%


Progress has been maintained, even with the acquisition of Bassi SRL and inclusion of its suppliers for the first time.
