Rule 13p-1 and the Securities and Exchange Commission&#8217;s adopting release and guidance are not clear on what it means to &#8220;contract to manufacture&#8221; and &#8220;influence the manufacturing.&#8221;  While Costco continues to assess which of its products are in scope of Rule 13p-1, it believes that it has interpreted &#8220;contract to manufacture&#8221; broadly for purposes of this filing. Costco&#8217;s objective is that our sourcing practices not support armed conflict or human rights abuses in the DRC.</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">To aid in identifying suppliers to include in its RCOI, Costco provided a third-party service, Source Intelligence (SI), with descriptive information for nonfood products that Costco sold during 2020, including whether Costco may have manufactured or contracted to manufacture those products. SI reviewed the product data using automated queries and a detailed quality-control check to determine which of those products might contain 3TG. If SI had doubt regarding the use of 3TG in products, the suppliers of the products were initially included in the RCOI process.</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The products SI initially flagged as in-scope, due to potential presence of 3TG, were those that are electronic or electrical, solar powered, contained any kind of metal (e.g., metal covering including alloys or metal hardware), or had unclear material content.

This information was used to determine which of our suppliers were in-scope for RCOIs. If in-scope, SI asked the suppliers to provide additional conflict minerals information. Suppliers were then engaged to collect information regarding the presence and sourcing of 3TG used in items sold to Costco.  SI provided Costco with lists of suppliers classified as out of scope for review and suppliers were re-engaged as needed, if requested by Costco, based on additional information about the products they supply and the nature of the relationship with Costco.</font></div><div><font><br></font></div><div style="border-bottom:1pt solid black;margin-bottom:5pt;margin-top:10pt;width:150pt"></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:6.5pt;font-weight:400;line-height:120%;position:relative;top:-3.5pt;vertical-align:baseline">1</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> </font><font style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">A Tier 1 retail supplier is one that provides products directly to a retailer such as Costco. </font></div><div style="height:72pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">1</font></div><div style="text-align:center"><font><br></font></div></div></div><hr style="page-break-after:always"><div style="min-height:72pt;width:100%"><div><font><br></font></div></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Reasonable Country of Origin Inquiry (RCOI)</font></div><div><font><br></font></div><div style="margin-bottom:5pt"><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">SI engaged Costco&#8217;s suppliers to collect information about the presence and sourcing of 3TG used in the products and components supplied to Costco. The program utilized the Responsible Minerals Initiative&#8217;s (RMI)&#160;Conflict Minerals Reporting Template (CMRT). Only reports using CMRT&#8217;s version 4.0 or higher were accepted. Suppliers were offered two options to submit the required information, either by uploading the CMRT in Microsoft Excel format or by completing an online survey version of this template directly in the SI platform.</font><font style="background-color:#ffffff;color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%"> In certain cases if a supplier was unable to complete on the platform, Costco or SI uploaded the CMRT.</font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">Supplier Engagement</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Costco provided SI with methods of contact for each supplier designated as in-scope. Generally, Costco and SI used email as the method of communication and followed with phone calls where appropriate and as described below.  The RCOI began with an introduction email from Costco to suppliers describing the Conflict Minerals Compliance Program (CMCP) requirements and identifying SI as a partner. SI then sent a subsequent email to suppliers containing a registration and survey request link for the online data collection platform.</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">To increase awareness of the CMCP, the initial registration email sent to Costco&#8217;s suppliers provided them with supporting regulations and frequently asked questions concerning 3TG mineral tracing and introduced them to the SI Conflict Minerals Supplier Resource Center (</font><font style="color:#7030a0;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">https&#58;&#47;&#47;conflictmineralsresources.com</font><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">).

Suppliers who remained non-responsive were contacted by telephone and offered assistance. This assistance included, but was not limited to, further information about the CMCP, an explanation of why the information was being collected, a review of how the information would be used, and clarification regarding how the information needed could be provided.</font></div><div style="padding-left:36pt"><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">Escalation</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">If after these efforts a supplier still did not register with the system or provide the information requested, an escalation process was initiated. It consisted of direct outreach by Costco. We contacted these suppliers by email to request their participation. SI followed up with a re-invitation to the platform.</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">Information Requested</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Suppliers were given a final deadline of April 14, 2021 to provide information about the mineral processors in their supply chains. Suppliers were asked to provide information regarding the sourcing of their conflict minerals, with the ultimate goal of identifying the 3TG smelters or refiners (SORs) and the country of origin of the conflict minerals. Suppliers who had already performed a RCOI through the use of the CMRT were asked to upload this document into the SI system or to provide this information in the online survey version. Suppliers had the ability to share information at a level with which they were most comfortable, i.e., company, product or user-defined, but the scope of the declaration had to be specified. Suppliers were asked to provide an electronic signature before submitting their data to Costco to verify that all answers submitted were accurate to the best of the supplier&#8217;s knowledge.</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline">Quality Assurance</font></div><div><font><br></font></div><div><font style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Supplier responses were evaluated by SI and Costco&#8217;s Conflict Mineral Team for plausibility, consistency, and completeness.
