(the &#147;Trust&#148;), as of and for the year ended August 31, 2010, in accordance with the standards of the Public Company Accounting Oversight Board (United States), we considered the Trust&#146;s internal control over financial reporting, including controls over safeguarding securities, as a basis for designing our auditing procedures for the purpose of expressing our opinion on the financial statements and to comply with the requirements of Form N-SAR, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting.&nbsp; Accordingly, we express no such opinion.</P>

hat transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of a company's assets that could have a material effect on the financial statements.</P>
