NOTES TO SCHEDULE OF INVESTMENTS

(a)      Non-income producing

(b)      Certificates of Deposit and Commercial Paper that are traded through
         Bills Finance Corporations must be guaranteed by either a bank, a trust
         company or a Bills Finance Corporation. Since there is no recognized
         credit rating system in the Republic of China, the guarantee may not be
         comparable to a guarantee issued by a U.S. institution.

(c)      All securities, including those traded over-the-counter for which
         market quotations are readily available, are valued at the last sales
         price prior to the time of determination of the Fund's net asset value
         per share or, if there were no sales on such date, at the closing price
         quoted for such securities (but if bid and asked quotations are
         available, at the mean between the last current bid and asked prices,
         rather than such quoted closing price). In certain instances where the
         price determined above may not represent fair market value, the value
         is determined in such manner as the Board of Directors may prescribe.
         Short-term investments, having a maturity of 60 days or less, are
         valued at amortized cost, which approximates market value, with accrued
         interest or discount earned included in interest receivable.

(d)      In connection with transactions in repurchase agreements, it is the
         Fund's policy that its custodian take possession of the underlying
         collateral securities, the fair value of which exceeds the principal
         amount of the repurchase transaction, including accrued interest, at
         all times. If the seller defaults, and the fair value of the collateral
         declines, realization of the collateral by the Fund may be delayed or
         limited by legal proceedings.


*        At May 31, 2005, aggregate gross unrealized appreciation for all
         securities for which there was an excess of value over financial
