Notes to Investment Portfolio:

* Security Valuation:

Debt securities generally are valued by pricing services approved by the Trust’s Board of Trustees, based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes. Debt securities for which quotations are readily available are valued at an over-the-counter or exchange bid quotation. Certain debt securities, which tend to be more thinly traded and of lesser quality, are priced based on fundamental analysis of the financial condition of the issuer and the estimated value of any collateral. Valuations developed through pricing techniques may vary from the actual amounts realized upon sale of the securities, and the potential variation may be greater for those securities valued using fundamental analysis.

Short-term debt obligations maturing within 60 days are valued at amortized cost, which approximates market value.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

Investments for which market quotations are not readily available, or quotations which management believes are not appropriate, are valued at fair value as determined in good faith under consistently applied procedures established by and under the general supervision of the Board of Trustees.

(a) Zero coupon bond.

(b) The issuer has filed for bankruptcy protection under Chapter 11, and is in default of certain debt covenants. Income is not being accrued. As of February 28, 2005, the value of these securities amounted to $817,090, which represents 0.6% of net assets.

(d) The Trust has been informed that the issuer has placed direct obligations of the U.S. Government in an irrevocable trust, solely for the payment of principle and interest.

(e) Security exempt from registration pursuant to Rule 144A under the Securities Act of 1933. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers. At February 28, 2005, these securities amounted to $2,688,632, which represents 2.1% of net assets.

(f) The issuer has filed for bankruptcy protection under Chapter 11. Income is being accrued. As of February 28, 2005, the value of these securities amounted to $649,620, which represents 0.5% of net assets.

(g) Variable rate security. The interest rate shown reflects the rate as of February 28, 2005.

(h) A portion of the security with a market value of $887,299 is pledged as collateral for open futures contracts.

(i) Variable rate demand notes. These securities are payable upon demand and are secured by letters of credit or other credit support agreements from banks. The interest rates change periodically and the interest rates shown reflects the rate as of February 28, 2005.

(j) Cost for federal income tax purposes is $178,856,760.

(k) Unrealized appreciation and depreciation at February 28, 2005, based on cost of investments for federal income tax purposes was:
