We are a public accounting firm registered with the Public CompanyAccounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan inaccordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and ExchangeCommission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan andperformthe audits 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, an auditof its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internalcontrol over financial reporting, but not for purposes of expressing an opinion on the effectiveness of the Plan’s internalcontrol 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 as evaluatingthe overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
