We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan andperformthe audit to obtain reasonable assurance about whether the financial statements are free of materialmisstatement, whether due to error or fraud. As part of our audit, we are required to obtain an understanding of internalcontrol over financial reporting, but not for the purposes of expressing an opinion on the effectiveness of the Plan’sinternal control over financial reporting.
