Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report.
Conflict Minerals Disclosure

The products named in this report were either manufactured by Kulicke and Soffa Industries, Inc. (“K&S” or the “Company”) or contracted by the Company to be manufactured. The listed products may contain conflict minerals necessary to their functionality or production.
The Company focused its due diligence process on equipment and the corresponding spares that were sold during the year ended December 31, 2017 ("Covered Products"). There are certain legacy spare parts pertaining to discontinued equipment products, that constitute an insignificant portion of the Company's total sales. These have been excluded in this report as these are discontinued products and the proportion of sale of such spares will further decline in the coming years. Products and prototypes which were manufactured but not sold during the year ended December 31, 2017 are also excluded in this report.
With regard to the conflict minerals used in the products named in this report, pursuant to Rule 13p-1 under the Securities Exchange Act ("the Rule"), the Company has conducted in good faith a reasonable country of origin inquiry ("ROCI") designed to determine whether any of the conflict minerals originated in the Democratic Republic of Congo (the “DRC”) or an adjoining country or are from recycled or scrapped sources.
The Company also undertook due diligence on the source and chain of custody of necessary conflict minerals contained in its Covered Products. Its due diligence approach was designed to conform in all material respects with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related Supplements (“OECD Guidance”).
The results of the Company’s reasonable country of origin inquiry can be found in the Company’s Conflict Minerals Report. A copy of Kulicke and Soffa Industries, Inc.’s Conflict Minerals Report is filed as Exhibit 1.01 hereto and is publicly available at We are not including the information contained on our website as a part of, or incorporating it by reference into, this filing.

Engineering team and efforts to analyze for presence of 3TG
Generally, our Engineering team analyzed each part in the Bill of Materials ("BOM") for presence of tantalum, tin, tungsten and gold (collectively, "3TG"). If the part did not contain 3TG, there was no further action taken and the Company's database was updated. The drawing and data sheet and material composition were examined. The following is a flow chart illustrating the approach taken by the Engineering team:
Each part was listed in a file as per the below example:
The file contains a listing of each item by part number, a description of the part, the material contained in the part, the finishing of the part, a column for each 3TG item, and a course of action. Under the "Action" column, it was noted "Yes" if the part contained 3TG or was undeterminable, and "No" if there was no presence of 3TG. If it was established that the item did contain 3TG or was undeterminable, the part was referred to the Supply Chain department for identification of the supplier of the part.
For certain subsidiaries, we sent the Electronics Industry Citizenship Coalition/Global e-Sustainability Initiative Conflict Minerals Reporting Template ("CMRT") to the top 90% of the suppliers in terms of total purchases.
Supply chain and efforts to determine country of origin
Generally, the Supply Chain team linked each part to the purchasing function to identify the supplier of the material, component or sub assembly. The CMRTs were forwarded to our direct suppliers ("Tier-1 suppliers") to establish the source of the 3TG for each of the items that were identified to contain 3TG. Each CMRT included questions regarding the Company’s conflict-free policy, engagement with its direct suppliers, and a listing of the smelters that the Company and its suppliers use. In addition, the template contained questions about the origin of conflict minerals included in their products, as well as the suppliers' due diligence.
The Conflict Minerals document package sent to the Company's Tier-1 suppliers contained the following:


Supplier Letter - Notification to suppliers that K&S is subject to Section 1502 of the Dodd-Frank Act, that K&S needs to comply and that their cooperation is requested.
K&S Conflict Minerals Policy
Conflict Minerals K&S Training Presentation
Standard communication documents were intended to be communicated through the Supply Chain to sub-suppliers.
Suppliers were expected to respond as follows:
Acknowledge the receipt of the request
Understand the Conflict Minerals Policy and K&S requirements
Perform due diligence on their supply chains to identify the smelter sources
Consolidate the sub-suppliers responses and integrate them into their responses
Submit the completed and signed CMRT to K&S within the requested time frame
A tracking system was implemented to monitor supplier response performance and due diligence progress. The responses received from suppliers were reviewed, and suppliers reporting 3TG items being purchased from the DRC or its adjoining countries were flagged and a risk mitigation strategy was developed for those suppliers.
The Company also holds a Supplier Day from time to time for most of its Tier-1 suppliers to, among other things, explain the requirements of the Conflict Minerals disclosure subsequent to the distribution of the standard communication documents. Presentations are made to the suppliers detailing the requirements of the Conflict Minerals rule and K&S's Conflict Minerals Policy.
We rely on our Tier-1 suppliers to provide information on the origin of the 3TG contained in components and sub-assemblies supplied to us - including the sources of 3TG that are supplied to them by their sub-suppliers. However, contracts with our suppliers are usually in force for three to five years or more and typically, we cannot unilaterally impose new contract terms and flow-down requirements, such as those required by our Conflict Minerals Policy, midway through such contracts, although we attempt and encourage our suppliers to adhere to those terms, to the extent possible.
As we enter into new contracts, or when our existing contracts come up for renewal, we are adding clauses to require our suppliers to submit their declaration per the CMRT. Because of our size, the complexity of our products, and the depth, breadth, and constant evolution of our supply chain, it is difficult to identify sub-suppliers upstream from our direct suppliers.
