Description of Principal Security Types

Money market securities are high-quality, short-term securities that pay a fixed, variable, or floating interest rate. Securities are often specifically structured so that they are eligible investments for a money market fund. For example, in order to satisfy the maturity restrictions for a money market fund, some money market securities have demand or put features, which have the effect of shortening the security's maturity. Money market securities include bank certificates of deposit, bankers' acceptances, bank time deposits, notes, commercial paper, and U.S. Government securities.

U.S. Government securities are high-quality securities issued or guaranteed by the U.S. Treasury or by an agency or instrumentality of the U.S. Government. U.S. Government securities may be backed by the full faith and credit of the U.S. Treasury, the right to borrow from the U.S. Treasury, or the agency or instrumentality issuing or guaranteeing the security.

A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price.

Principal Investment Risks

Many factors affect each fund's performance. A fund's yield will change daily based on changes in interest rates and other market conditions. Although each fund is managed to maintain a stable $1.00 share price, there is no guarantee that the fund will be able to do so. For example, a major increase in interest rates or a decrease in the credit quality of the issuer of one of a fund's investments could cause the fund's share price to decrease. While the funds will be charged premiums by a mutual insurance company for coverage of specified types of losses related to default or bankruptcy on certain securities, a fund may incur losses regardless of the insurance. It is important to note that neither the funds' share prices nor their yields are guaranteed by the U.S. Government.

The following factors can significantly affect a fund's performance:

Interest Rate Changes. Money market securities have varying levels of sensitivity to changes in interest rates. In general, the price of a money market security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities and the securities of issuers in the financial services sector can be more sensitive to interest rate changes. Short-term securities tend to react to changes in short-term interest rates.

Foreign Exposure. Issuers located in foreign countries and entities located in foreign countries that provide credit support or a maturity-shortening structure can involve increased risks. Extensive public information about the issuer or provider may not be available and unfavorable political, economic, or governmental developments could affect the value of the security.

Financial Services Exposure. Financial services companies are highly dependent on the supply of short-term financing. The value of securities of issuers in the financial services sector can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad.

Issuer-Specific Changes. Changes in the financial condition of an issuer, changes in specific economic or political conditions that affect a particular type of issuer, and changes in general economic or political conditions can affect the credit quality or value of an issuer's securities. Entities providing credit support or a maturity-shortening structure also can be affected by these types of changes. If the structure of a security fails to function as intended, the security could decline in value.

Fundamental Investment Policies

The policies discussed below are fundamental, that is, subject to change only by shareholder approval.

U.S. Government Reserves seeks as high a level of current income as is consistent with the security of principal and liquidity.

Cash Reserves seeks as high a level of current income as is consistent with preservation of capital and liquidity by investing in money market instruments.

Valuing Shares

Each fund is open for business each day the New York Stock Exchange (NYSE) is open.

Each fund's net asset value per share (NAV) is the value of a single share. Fidelity normally calculates each fund's NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. However, NAV may be calculated earlier if trading on the NYSE is restricted or as permitted by the Securities and Exchange Commission (SEC). Each fund's assets are valued as of this time for the purpose of computing the fund's NAV.

To the extent that each fund's assets are traded in other markets on days when the NYSE is closed, the value of the fund's assets may be affected on days when the fund is not open for business. In addition, trading in some of a fund's assets may not occur on days when the fund is open for business.

Each fund's assets are valued on the basis of amortized cost.

Short-term or excessive trading into and out of a fund may harm performance by disrupting portfolio management strategies and by increasing expenses. Accordingly, a fund may reject any purchase orders, including exchanges, particularly from market timers or investors who, in FMR's opinion, have a pattern of short-term or excessive trading or whose trading has been or may be disruptive to that fund. For these purposes, FMR may consider an investor's trading history in that fund or other Fidelity funds, and accounts under common ownership or control.

Selling Shares

The price to sell one share of each fund is the fund's NAV.

Your shares will be sold at the next NAV calculated after your order is received in proper form.

Certain requests must include a signature guarantee. It is designed to protect you and Fidelity from fraud. Your request must be made in writing and include a signature guarantee if any of the following situations apply:

You wish to sell more than $100,000 worth of shares;
Your account registration has changed within the last 15 or 30 days, depending on your account;
The check is being mailed to a different address than the one on your account (record address);
The check is being made payable to someone other than the account owner; or
The redemption proceeds are being transferred to a Fidelity account with a different registration.

You should be able to obtain a signature guarantee from a bank, broker (including Fidelity Investor Centers), dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.

When you place an order to sell shares, note the following:

If you are selling some but not all of your shares, leave at least $2,000 worth of shares in the account to keep it open ($500 for retirement accounts), except accounts not subject to account minimums.
Normally, Fidelity will process redemptions by the next business day, but Fidelity may take up to seven days to process redemptions if making immediate payment would adversely affect a fund.
Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected. This can take up to seven business days after a purchase.
Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.
Redemption proceeds may be paid in securities or other property rather than in cash if FMR determines it is in the best interests of a fund.

Policies

The following policies apply to you as a shareholder.

Statements and reports that Fidelity sends to you include the following:

Confirmation statements (after transactions affecting your account balance except reinvestment of distributions in the fund or another fund and certain transactions through automatic investment or withdrawal programs).
Monthly or quarterly account statements (detailing account balances and all transactions completed during the prior month or quarter).
Financial reports (every six months).

To reduce expenses, only one copy of most financial reports and prospectuses may be mailed to households, even if more than one person in the household holds shares of a fund. Call Fidelity at 1-800-544-8544 if you need additional copies of financial reports or prospectuses. If you do not want the mailing of these documents to be combined with those for other members of your household, contact Fidelity in writing at P.O. Box 5000, Cincinnati, Ohio 45273-8692.

Electronic copies of most financial reports and prospectuses are available at Fidelity's web site. To participate in Fidelity's electronic delivery program, call Fidelity or visit Fidelity's web site for more information.

You may initiate many transactions by telephone or electronically. Fidelity will not be responsible for any losses resulting from unauthorized transactions if it follows reasonable security procedures designed to verify the identity of the investor. Fidelity will request personalized security codes or other information, and may also record calls. For transactions conducted through the Internet, Fidelity recommends the use of an Internet browser with 128-bit encryption. You should verify the accuracy of your confirmation statements immediately after you receive them. If you do not want the ability to sell and exchange by telephone, call Fidelity for instructions.

When you sign your account application, you will be asked to certify that your social security or taxpayer identification number is correct and that you are not subject to 31% backup withholding for failing to report income to the IRS. If you violate IRS regulations, the IRS can require a fund to withhold 31% of your taxable distributions and redemptions.

Shareholder Information - continued

Fidelity may deduct an annual maintenance fee of $12.00 from accounts with a value of less <R>than $2,000.</R> It is expected that accounts will be valued on the second Friday in November of each year. Accounts opened after September 30 will not be subject to the fee for that year. The fee, which is payable to Fidelity, is designed to offset in part the relatively higher costs of servicing smaller accounts. This fee will not be deducted from accounts <R>opened</R> <R>after January 1, 2001</R> using regular investment plans.

If your account balance falls below $2,000 (except accounts not subject to account minimums), you will be given 30 days' notice to reestablish the minimum balance. If you do not increase your balance, Fidelity may close your account and send the proceeds to you. Your shares will be sold at the NAV on the day your account is closed.

Fidelity may charge a fee for certain services, such as providing historical account documents.

Dividends and Capital Gain Distributions

Each fund earns interest, dividends, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. Each fund may also realize capital gains from its investments, and distributes these gains (less losses), if any, to shareholders as capital gain distributions.

Distributions you receive from each fund consist primarily of dividends. Each fund normally declares dividends daily and pays them monthly.

Earning Dividends

Shares begin to earn dividends on the first business day following the day of purchase.

Shares earn dividends until, but not including, the next business day following the day of redemption.

Distribution Options

When you open an account, specify on your application how you want to receive your distributions. The following options may be available for each fund's distributions:

1. Reinvestment Option. Your dividends and capital gain distributions, if any, will be automatically reinvested in additional shares of the fund. If you do not indicate a choice on your application, you will be assigned this option.

2. Cash Option. Your dividends and capital gain distributions, if any, will be paid in cash.

3. Directed Dividends^® Option. Your dividends will be automatically invested in shares of another identically registered Fidelity fund. Your capital gain distributions, if any, will be automatically invested in shares of another identically registered Fidelity fund, automatically reinvested in additional shares of the fund, or paid in cash.

Not all distribution options are available for every account. If the option you prefer is not listed on your account application, or if you want to change your current option, call Fidelity.

If you elect to receive distributions paid in cash by check and the U.S. Postal Service does not deliver your checks, your distribution option may be converted to the Reinvestment Option. You will not receive interest on amounts represented by uncashed distribution checks.

Tax Consequences

As with any investment, your investment in a fund could have tax consequences for you. If you are not investing through a tax-advantaged retirement account, you should consider these tax consequences.

Distributions you receive from each fund are subject to federal income tax, and may also be subject to state or local taxes.

For federal tax purposes, each fund's dividends and distributions of short-term capital gains are taxable to you as ordinary income, while each fund's distributions of long-term capital gains, if any, are taxable to you generally as capital gains.

Any taxable distributions you receive from a fund will normally be taxable to you when you receive them, regardless of your distribution option. If you elect to receive distributions in cash or to invest distributions automatically in shares of another Fidelity fund, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Fund Management

Each fund is a mutual fund, an investment that pools shareholders' money and invests it toward a specified goal.

FMR is each fund's manager.

As of <R>March 31, 2000</R>, FMR had approximately $<R>639.1</R> billion in discretionary assets under management.

As the manager, FMR is responsible for choosing each fund's investments and handling its business affairs.

Fidelity Investments Money Management, Inc. (FIMM), in Merrimack, New Hampshire, serves as a sub-adviser for each fund. FIMM is primarily responsible for choosing investments for each fund.

FIMM is an affiliate of FMR. As of <R>March 31, 2000</R>, FIMM had approximately $<R>206.8 billion</R> in discretionary assets under management.

From time to time a manager, analyst, or other Fidelity employee may express views regarding a particular company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed and do not necessarily represent the views of Fidelity or any other person in the Fidelity organization. Any such views are subject to change at any time based upon market or other conditions and Fidelity disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Fidelity fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any Fidelity fund.

Each fund pays a management fee to FMR. The management fee is calculated and paid to FMR every month.

The monthly management fee for each fund is calculated by adding a group fee to an income-related fee.

The income-related fee varies <R>depending on the level of the fund's monthly gross income</R> from an annualized rate of 0.05% (at a fund annualized gross yield of 0%) to 0.27% (at a fund annualized gross yield of 15%) of the fund's average net assets throughout the month.

The group fee rate is based on the average net assets of all the mutual funds advised by FMR. This rate cannot rise above 0.37%, and it drops as total assets under management increase. The group fee rate is divided by twelve and multiplied by the fund's average net assets throughout the month.

For November 2000, the group fee rate was <R>0.1263</R>%.

The total management fee for the fiscal year ended November 30, 2000, was <R>0.23</R>% of the fund's average net assets for U.S. Government Reserves and <R>0.24</R>% of the fund's average net assets for Cash Reserves. For the fiscal year ended November 30, 2000, each fund paid FMR a management fee composed of a group fee, an individual fund fee of 0.03% of the fund's average net assets, and an income-based fee of 6% of the fund's monthly gross income in excess of an annualized 5% yield.

FMR pays FIMM for providing sub-advisory services.

FMR may, from time to time, agree to reimburse the funds for management fees and other expenses above a specified limit. FMR retains the ability to be repaid by a fund if expenses fall below the specified limit prior to the end of the fiscal year. Reimbursement arrangements, which may be discontinued by FMR at any time, can decrease a fund's expenses and boost its performance.

Fund Distribution

Fidelity Distributors Corporation (FDC) distributes each fund's shares.

Each fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 that recognizes that FMR may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of fund shares and/or shareholder support services. FMR, directly or through FDC, may pay significant amounts to intermediaries, such as banks, broker-dealers, and other service-providers, that provide those services. Currently, the Board of Trustees of each fund has authorized such payments.

If payments made by FMR to FDC or to intermediaries under a Distribution and Service Plan were considered to be paid out of a fund's assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.

To receive payments made pursuant to a Distribution and Service Plan, intermediaries must sign the appropriate agreement with FDC in advance.

From time to time, FDC may offer special promotional programs to investors who purchase shares of Fidelity funds. For example, FDC may offer merchandise, discounts, vouchers, or similar items to investors who purchase shares of certain Fidelity funds during certain periods. To determine if you qualify for any such programs, contact Fidelity or visit our web site at www.fidelity.com.

FMR may allocate brokerage transactions in a manner that takes into account the sale of shares of a fund, provided that the fund receives brokerage services and commission rates comparable to those of other broker-dealers.

No dealer, sales representative, or any other person has been authorized to give any information or to make any representations, other than those contained in this prospectus and in the related statement of additional information (SAI), in connection with the offer contained in this prospectus. If given or made, such other information or representations must not be relied upon as having been authorized by the funds or FDC. This prospectus and the related SAI do not constitute an offer by the funds or by FDC to sell shares of the funds to or to buy shares of the funds from any person to whom it is unlawful to make such offer.
