NOTES TO FINANCIAL STATEMENTS (Unaudited) July 31, 2007


SECURITY VALUATION

Securities listed on a domestic securities exchange are valued based on the last sale price as of the close of regular trading hours on the New York Stock Exchange or, in the absence of recorded sales, are valued at the most recent bid price. Securities for which the primary market is the National Association of Securities Dealers Automated Quotations National Market System ("NASDAQ") are valued at the NASDAQ Official Closing Price. The Funds invest in money market mutual funds, which are valued at NAV.

Securities, for which market quotations are not readily available, including investments that are subject to limitations as to their sale, are valued at fair value as determined in good faith by the Advisor in accordance with the procedures adopted by the Board of Trustees. In determining fair value, consideration is given to market conditions, relative benchmarks and other financial data.

On September 15, 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standard No. 157 Fair Value Measurement ("FAS 157") which provided enhanced guidance for using fair value to measure assets and liabilities. The standard requires companies to provide expanded information about the assets and liabilities measured at fair value and the potential effect of these fair valuations on an entity's financial performance. The standard does not expand the use of fair value in any new circumstances, but provides clarification on acceptable fair valuation methods and applications. Adoption of FAS 157 is required for fiscal years beginning after November 15, 2007. The standard is not expected to materially impact the Funds' financial statements.
