In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2020 and 2019, and the changes in net assets available for benefits for the years ended December 31, 2020 and 2019, in conformity with accounting principles generally accepted in the United States of America.</font></div><div style="margin-top:12pt;text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Basis for Opinion</font></div><div style="margin-top:12pt;text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">These financial statements are the responsibility of the Plan&#8217;s management. Our responsibility is to express an opinion on the Plan&#8217;s financial statements based on our audits.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan&#8217;s internal control over financial reporting. Accordingly, we express no such opinion.</font></div><div style="margin-top:12pt;text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">Our audits included performing procedures to assess the risk of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by the Plan&#8217;s management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.</font></div><div style="margin-top:12pt;text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Supplemental Information</font></div><div style="margin-top:12pt;text-align:justify"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2020 has been subjected to audit procedures performed in conjunction with the audit of the Plan&#8217;s financial statements. The supplemental information is presented for the purpose of additional analysis and is not a required part of the financial statements but included supplemental information required by the Department of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental information is the responsibility of the Plan&#8217;s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor&#8217;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.

of WESCO common stock and a short-term cash component that provided liquidity for daily trading. WESCO common stock was valued at the quoted closing market price from a national securities exchange and the short-term cash investment was valued at cost, which approximated fair value. As of December&#160;31, 2019, the WESCO International Pooled Stock Fund was classified as a Level 2 investment due to the pooling of WESCO common stock and the short-term cash component. In connection with the transition of the Plan's trustee and recordkeeper, as described in Note 1, investments in the WESCO International Pooled Stock Fund converted to the WESCO Stock Fund. This investment is valued primarily using the quoted closing market price from a national securities exchange of WESCO International, Inc's common stock and is therefore classified as Level 1 in the fair value hierarchy as of December&#160;31, 2020.</font></div><div style="margin-bottom:9pt;margin-top:9pt;padding-left:27pt;text-align:justify;text-indent:-18pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:5.85pt;font-weight:400;line-height:120%;position:relative;top:-3.15pt;vertical-align:baseline">(2)&#160;&#160;&#160;&#160;</font><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The Wells Fargo&#47;BlackRock S&#38;P 500 Index CIT (N20) fund is a common&#47;collective trust fund, which is measured using the NAV per share practical expedient based on the underlying equity securities of companies that compose the Standard &#38; Poor's 500 Index (the &#34;Index&#34;), and therefore was not classified in the fair value hierarchy as of December&#160;31, 2019.
