Section 1 - Conflict Minerals Disclosure

Item 1.01. Conflict Minerals Disclosure and Report

(a) Conflict minerals are necessary to the functionality or production of certain of the products manufactured by the registrant or contracted by the registrant to be manufactured and are required to be reported in the calendar year covered by this specialized disclosure report. Registrant does not purchase the conflict minerals directly from smelters or mines and as a result registrant conducted in good faith a reasonable country of origin inquiry with its suppliers and undertook due diligence measures reasonably designed to determine whether any of the conflict minerals originated in the Democratic Republic of the Congo or an adjoining country or are from recycled or scrap sources.

(b) Based on its reasonable country of origin inquiry and due diligence measures, the registrant determined that its necessary conflict minerals used in certain of the products manufactured by the registrant or contracted by the registrant to be manufactured did or may have originated in the Democratic Republic of the Congo or an adjoining country and that they may not be from recycled or scrap sources. The registrant exercised due diligence on the source and chain of custody of such conflict minerals that conforms to the nationally due diligence framework as set forth in the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. The reasonable country of origin inquiry and due diligence measures that registrant undertook included requesting all relevant first-tier suppliers to complete the CFSI Conflict Minerals Reporting Template (CMRT) which can be found at http://www.conflictfreesourcing.org, reviewing the information and smelter data provided by relevant first-tier suppliers, and comparing smelters and refiners identified by the supply chain to independently verified lists (e.g., the CFSI Conflict-Free Smelter Program (CFSP) list which can be found at http://www.conflictfreesourcing.org ). The registrant has disclosed this information on its publicly available Internet website at the following link: http:/www.ctscorp.com/resource-center/guidelines-and-policies/Conflict Minerals Policy. The registrant is also filing a Conflict Minerals Report as an exhibit to its specialized disclosure report and has provided that report on its publicly available Internet website at the following link: http:/www.ctscorp.com/resource-center/guidelines-and-policies/Conflict Minerals Form SD.
