Exhibit

WESCO is a North American-based distributor of products and provider of advanced supply chain management and logistics services used in industrial, construction, utility and commercial, institutional and government markets. WESCO’s primary distribution product categories include general electrical and industrial supplies, wire, cable and conduit, data and broadband communication, power distribution equipment, lighting and lighting control systems, control and automation, and motors. In its primary role as a distributor, WESCO is not manufacturing or contracting to manufacture, and is therefore not subject to the conflict minerals rule. However, in a very small portion of its business, WESCO is manufacturing or contracting to manufacture within the scope of the conflict minerals rule. The following represent product categories where WESCO is manufacturing or contracting to manufacture: enclosures, machined cable assemblies, grounding grids, pole line hardware, light fixtures and audio visual equipment. The direct suppliers supporting the production of these product categories were included in the due diligence process detailed within the CMR.

WESCO relied on its suppliers to provide information on the origin of the conflict minerals contained in the relevant components and materials supplied to WESCO. In its efforts to comply with the disclosure requirements and obtain the accurate data from its suppliers, WESCO contacted suppliers who manufactured or contracted to manufacture products where the nature of the product supplied to WESCO was considered to be reasonably likely to contain conflict minerals. In addition to providing WESCO the requisite data for its SEC reporting, the data collected is further analyzed by WESCO to determine the origin of conflict minerals in WESCO’s supply chain and WESCO’s path moving forward with regard to conflict-free sourcing. As WESCO enters into new contracts with suppliers, WESCO includes language requiring suppliers to provide WESCO information regarding the origin of any conflict minerals and related smelters. In addition, WESCO includes similar requirements in its standard terms and conditions of purchase. Over time, these contractual measures are intended to improve consistency and transparency in WESCO’s supply chain.

WESCO is typically many tiers downstream in the supply chain from the source of the raw minerals. Based on the responses from its suppliers, WESCO was unable to determine the origin of the conflict minerals in its manufactured or contracted to manufacture products, and, in some cases, whether they even contain conflict minerals. Therefore, WESCO cannot exclude the possibility that some may have originated in the Covered Countries. For the products that WESCO is manufacturing or contracting to manufacture and which are subject to the reporting obligations of Rule 13p-1, WESCO was unable to determine the origin of the conflict minerals they may contain and/or to determine whether they come

Therefore, for reporting year 2017, WESCO is submitting this Conflict Minerals Report (CMR) as Exhibit 1.01 to Form SD. In accordance with the OECD Guidance and the Conflict Minerals Rule, this report is available on WESCO’s website, http://wesco.investorroom.com.

WESCO has conducted due diligence to identify and trace the conflict minerals in its supply chain using the EICC-GeSI Conflict Minerals Reporting Template (CMRT), and WESCO engaged Assent Compliance to assist in WESCO’s data collection and compliance efforts. Assent Compliance requested suppliers to complete a CMRT and included training and education to guide suppliers on best practices and the use of this template. Assent Compliance monitored and tracked all communications in the Assent Compliance Manager (ACM) platform for reporting and transparency. WESCO contacted suppliers that were unresponsive to Assent Compliance’s communications during the diligence process and requested such suppliers to complete the CMRT and submit such template to Assent Compliance.

WESCO has adopted the CMRT in collecting its supplier data, and WESCO has contacted suppliers of products WESCO manufactured or contracted to manufacture via Assent Compliance. Non-responsive suppliers or suppliers who provided incomplete or invalid responses were contacted on multiple occasions in an effort to obtain accurate data collection for the reporting period. The supplier data has been uploaded into the ACM platform to allow WESCO licensed users to view, analyze, and document the overall progress of WESCO’s data collection efforts. WESCO intends to continue to add supplier information to this database as suppliers respond.

WESCO plans to continue to analyze the data provided by the suppliers of products manufactured or contracted to be manufactured to determine whether those products contain conflict minerals from the Covered Countries. WESCO is attempting to identify the smelters in its supply chain based on the information gathered through the CMRT to determine whether the smelters have been certified as conflict free. By utilizing the annual disclosure and inserting disclosure requirements into its supplier contracts, WESCO continues to facilitate supply chain compliance with the conflict minerals rule.

WESCO has established a system for conflict minerals which includes a cross-functional internal team. The internal team is responsible for identifying WESCO’s products that are subject to the rule and implementing WESCO’s conflict minerals policy. The team is led by a conflict minerals Project Manager, who serves as a central point of contact across WESCO.

WESCO’s controls include use of the ACM platform to archive WESCO’s supplier declarations, oversight and direction by the Project Manager, and conflict minerals contractual provisions included in new supplier agreements and purchase orders.

With respect to the OECD requirement to strengthen engagement with suppliers, WESCO has engaged its suppliers by communications delivered via Assent Compliance and by working with suppliers directly, and this year we emphasized supplier education and training. To accomplish this, WESCO utilized Assent Compliance’s learning management system, Assent University, and provided suppliers access to their Conflict Minerals training course. This training is tracked and evaluated based on completion.

WESCO has licensed the ACM platform application to archive its supplier declarations, providing evidence of its due diligence process. Licensed WESCO users, which are part of the internal team above, maintain access and the ability to review the CMRTs and information disclosed by the suppliers.

WESCO evaluated its business activities as they relate to the conflict minerals rule. As a result of its evaluation, WESCO identified suppliers for products WESCO is manufacturing or contracting to manufacture that may contain conflict minerals, and WESCO contacted those suppliers. A portion of the suppliers provided disclosures with information about the existence of and source of conflict minerals contained in the components or materials supplied to WESCO.

The team meets on a regular basis to discuss the strategy, any issues, and WESCO’s path moving forward. As described herein, WESCO has engaged its suppliers where WESCO reasonably believed that products it manufactured or contracted to manufacture contained conflict minerals. WESCO has been unable to determine with certainty whether ultimate sources of conflict minerals may support conflict in the Covered Countries. If WESCO were to determine with certainty that a supplier was supplying conflict minerals from a source supporting such conflict, WESCO would work to establish an alternative source of conflict minerals that does not support such conflict, as provided in the OECD guidance.

Relevant suppliers were contacted by Assent Compliance and asked to disclose the use and source of any conflict minerals using the CMRT. The WESCO internal team was involved with the communications and in the response results. WESCO further directed Assent Compliance in escalation efforts for those suppliers failing to respond or providing an incomplete or insufficient response. In addition, WESCO was able to track the response rate and content throughout the data collection process.

WESCO and/or Assent Compliance contacted relevant suppliers by email communication at least five times. Supplier training was provided within the time frame, providing the suppliers direction and guidance in completing their response. Suppliers that did not reply after three email communications

The overall response rate increased by 1% from reporting year 2016 and was approximately 57% in total. Some of the responses received provided data at a company or divisional level disclosure and were unable to specify the smelters or refiners used for components supplied to WESCO. In addition, some suppliers did not respond or refused to do so, despite repeated requests. WESCO is therefore unable to determine whether any of the conflict minerals reported by those suppliers were contained in components or parts supplied to WESCO or to validate that any of these smelters or refiners are actually in WESCO’s supply chain. In some cases, WESCO is unable to determine whether the product even contained conflict minerals.

WESCO believes it has expended reasonable efforts to determine the mine or origin of conflict minerals in products it manufactured or contracted to manufacture through its engagement of Assent Compliance and utilizing their platform to archive WESCO’s supplier declarations, in requesting its suppliers to complete the CMRT, reviewing their responses, and in implementing the OECD guidance.

Because WESCO is typically many tiers downstream from the raw material source, it relies on its suppliers to provide information on the origin of conflict minerals. Some of WESCO’s suppliers were primarily unable to represent to WESCO that conflict minerals from the processing facilities or smelters they listed had actually been included in components they supplied to WESCO. Therefore, WESCO is not able to include smelter names in this report.


a.	Identify those products manufactured or contracted to manufacture by WESCO and request conflict mineral disclosure from such suppliers.


b.	Scrutinize the data received from suppliers to identify potential risks, inconsistencies, and incomplete or incompatible data.


c.	Engage WESCO suppliers indicating they are using conflict minerals from the Covered Countries to promote conflict-free sourcing or seek alternative sources of supply.


d.	Continue to engage and train suppliers in an effort to improve compliance, increase response rate and content, and promote conflict-free sourcing.


e.	Include appropriate conflict mineral clauses in new supplier agreements and in purchase order contracts.


f.	Track the interpretation and direction of the conflict mineral rule as it relates to industry practices.
