Basis for Opinion These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinionon the Plan’s financial statements based on our audits. We are a public accounting firm registered with the PublicCompany Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect tothe Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securitiesand Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan andperform the audit to obtain reasonable assurance about whether the financial statements are free of materialmisstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, anaudit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding ofinternal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of thePlan’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements,whether due to error or fraud, and performing procedures that respond to those risks. Such procedures includedexamining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits alsoincluded evaluating the accounting principles used and significant estimates made by management, as well asevaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis forour opinion.

Ouraudit procedures included determining whether the information reconciles to the financial statements or the underlyingaccounting and other records, as applicable, and performing procedures to test the completeness and accuracy of theinformation presented in the supplemental schedule. In forming our opinion on the information, we evaluated whethersuch information, including its form and content, is presented in conformity with the Department of Labor’s Rules andRegulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.
