Principal Investment Strategies

The Fund seeks to attain this objective by investing in municipal obligations of Hawaiian issuers to the extent that obligations of the desired quality, maturity and interest rate are available; otherwise by investing in similar obligations of non-Hawaii issuers. These obligations must have remaining maturities not exceeding 397 days, must be of high quality and must present minimal credit risks. At least 80% of the Tax-Free Fund’s assets must be invested in Municipal Obligations (as defined below).

Under the current management policies, the Fund invests only in the following types of obligations:

Municipal Obligations

The term “Municipal Obligations” is used to mean obligations with maturities of 397 days or less paying interest which, in the opinion of bond counsel or other appropriate counsel, is exempt from regular Federal income taxes. “Hawaiian Obligations” are Municipal Obligations, including those of Guam, the Northern Mariana Islands, Puerto Rico and the Virgin Islands, paying interest which, in the opinion of bond counsel or other appropriate counsel, is also exempt from Hawaii state income taxes.

Since it is not possible to predict the extent to which suitable Hawaiian Obligations will be available for investment, the Tax-Free Fund has no investment restriction limiting the proportion of its portfolio which it may invest in other Municipal Obligations.

           Municipal Obligations are debt obligations issued by or on behalf of states, cities, municipalities and other public authorities. Such obligations include:

Municipal Bonds

Municipal bonds generally have a maturity at the time of issuance of up to 30 years. The Fund can purchase only those with a remaining maturity of 13 months or less.

Municipal Notes

Municipal notes generally have maturities at the time of issuance of three years or less. These notes are generally issued in anticipation of the receipt of tax funds, of the proceeds of bond placements or of other revenues. The ability of an issuer to make payments is therefore dependent on these tax receipts, proceeds from bond sales or other revenues, as the case may be.

Municipal Commercial Paper

Municipal commercial paper is a debt obligation with a stated maturity of 397 days or less that is issued to finance seasonal working capital needs or as short-term financing in anticipation of longer-term debt.

Tender Option Bonds

Tender option bonds are floating or variable rate demand instruments paying interest at the prevailing short-term tax-exempt rate, synthetically created in the secondary market by their sponsors by coupling, in each case, a municipal bond with an option to tender the bond at par.

The Fund seeks to maintain a net asset value of $1.00 per share. Under applicable regulations, it is subject to related maturity, quality, diversification and liquidity requirements.

Principal Risks

The Fund’s assets, being primarily Hawaiian issues, are subject to economic and other conditions affecting Hawaii. Adverse local events, such as a downturn in the Hawaiian economy, could affect the value of the Fund’s portfolio.

An investment in the Fund is not a deposit in, nor endorsed or guaranteed by, any bank, and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the Fund.

The Fund’s right to obtain payment at par on a demand instrument could be affected by events occurring between the date the Fund elects to demand payment and the date payment is due that may affect the ability of the issuer of the instrument to make payment when due, except when such demand instrument permits same day settlement. To facilitate settlement, these same day demand instruments may be held in book entry form at a bank other than the Fund’s custodian subject to a sub-custodial agreement approved by the Fund between that bank and the Fund’s custodian. Such obligations are also subject to credit risk.

Repurchase agreements involve some risk to the Fund if the other party does not fulfill its obligations under the agreement.

Tender option bonds are subject to credit risk and to the risk that circumstances may arise in which the tender option terminates.

The value of money-market instruments tends to fall if prevailing interest rates rise.

The taxable market is a broader and more liquid market with a greater number of investors, issuers and market makers than the market for Municipal Obligations. The more limited marketability of Municipal Obligations may make it difficult in certain circumstances to dispose of large investments advantageously. In general, Municipal Obligations are also subject to credit risks such as the loss of credit ratings or possible default. In addition, certain Municipal Obligations might lose tax-exempt status in the event of a change in the tax laws.
