Payments to Broker-Dealers and Other Financial Intermediaries

Fund Basics

Investment Details

Investment Objective

Fidelity® Treasury Only Money Market Fund seeks as high a level of current income as is consistent with the security of principal and liquidity.

Principal Investment Strategies

The Adviser normally invests at least 99.5% of the fund's total assets in cash and U.S. Treasury securities. The Adviser normally invests the fund's assets in securities whose interest is specifically exempt from state and local income taxes under federal law; such interest is not exempt from federal income tax.

In buying and selling securities for the fund, the Adviser complies with industry-standard regulatory requirements for money market funds regarding the quality, maturity, liquidity, and diversification of the fund's investments. The Adviser stresses maintaining a stable $1.00 share price, liquidity, and income.

In addition, the Adviser normally invests at least 80% of the fund's assets in U.S. Treasury securities.

Description of Principal Security Types

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.

Certain issuers of U.S. Government securities, including Fannie Mae, Freddie Mac, and the Federal Home Loan Banks, are sponsored or chartered by Congress but their securities are neither issued nor guaranteed by the U.S. Treasury.

Principal Investment Risks

Many factors affect the fund's performance. Developments that disrupt global economies and financial markets, such as pandemics and epidemics, may magnify factors that affect a fund's performance. The fund's yield will change daily based on changes in interest rates and other market conditions. Although the 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 the fund's investments could cause the fund's share price to decrease. It is important to note that neither share price nor yield is guaranteed by the U.S. Government.

The following factors can significantly affect the 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 certain types of securities, such as 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. In market environments where interest rates are rising, issuers may be less willing or able to make principal and/or interest payments on securities when due. Certain investments held by a fund may have relied on the London Interbank Offered Rate (LIBOR) (an indicative measure of the average interest rate at which major global banks could borrow from one another). As a result of benchmark reforms, publication of all LIBOR settings has ceased. Although the transition process away from certain benchmark rates, including LIBOR, for more instruments has been completed, any potential effects of the transition away from LIBOR and other benchmark rates on financial markets, a fund or the financial instruments in which a fund invests can be difficult to ascertain and may adversely impact a fund's performance.

Income Risk. The fund's income, or yield, is based on short-term interest rates, which can fluctuate significantly over short periods. A low or negative interest rate environment can adversely affect the fund's yield and, depending on its duration and severity, could prevent the fund from providing a positive yield and/or maintaining a stable $1.00 share price. In addition, the fund's yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates. From time to time, the Adviser may reimburse expenses or waive fees for a class of a fund in order to avoid a negative yield, but there is no guarantee that the class or fund will be able to avoid a negative yield.

Issuer-Specific Changes.Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value.

In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy (including leaving a significant portion of the fund's assets uninvested) for defensive purposes. Uninvested assets do not earn income for a fund, which may have a significant negative impact on the fund's yield and may prevent the fund from achieving its investment objective.

Fundamental Investment Policies

The following is fundamental, that is, subject to change only by shareholder approval:

Fidelity® Treasury Only Money Market Fund seeks as high a level of current income as is consistent with the security of principal and liquidity.

Shareholder Notice

The following is subject to change only upon 60 days' prior notice to shareholders:

Fidelity® Treasury Only Money Market Fund normally invests at least 99.5% of its total assets in cash and U.S. Treasury securities and at least 80% of its assets in U.S. Treasury securities.

Valuing Shares

The fund is open for business each day the NYSE is open.

Even if the NYSE is closed, a money market fund will be open for business on those days on which the New York Fed is open, the primary trading markets for the money market fund's portfolio instruments are open, and the money market fund's management believes there is an adequate market to meet purchase and redemption requests.

The NAV is the value of a single share. Fidelity normally calculates NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. The fund's assets normally are valued as of this time for the purpose of computing NAV. Fidelity calculates NAV separately for each class of shares of a multiple class fund.

NAV is not calculated and the fund will not process purchase and redemption requests submitted on days when the fund is not open for business. The time at which shares are priced and until which purchase and redemption orders are accepted may be changed as permitted by the Securities and Exchange Commission (SEC).

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

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

Shareholder Information

Additional Information about the Purchase and Sale of Shares

As used in this prospectus, the term "shares" generally refers to the shares offered through this prospectus.

General Information

Certain methods of contacting Fidelity may be unavailable or delayed (for example, during periods of unusual market activity). In addition, the level and type of service available may be restricted. 

Frequent Purchases and Redemptions

The fund may reject for any reason, or cancel as permitted or required by law, any purchase orders, including transactions deemed to represent excessive trading, at any time. 

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to the fund (such as spreads paid to dealers who sell money market instruments to a fund) and disrupting portfolio management strategies. 

The Adviser anticipates that shares of Fidelity® Treasury Only Money Market Fund will be purchased and sold frequently because a money market fund is designed to offer a liquid cash option. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive trading of fund shares and Fidelity® Treasury Only Money Market Fund accommodates frequent trading.  

Fidelity® Treasury Only Money Market Fund has no limit on purchase transactions but may in its discretion restrict, reject, or cancel any purchases that, in the Adviser's opinion, may be disruptive to the management of the fund or otherwise not be in the fund's interests. 

The fund reserves the right at any time to restrict purchases or impose conditions that are more restrictive on excessive trading than those stated in this prospectus.  

Shares of the fund offered through this prospectus have no exchange privilege with any other fund.

Buying Shares

Eligibility

Shares are offered only to certain Stock Plan Services accounts.

There is no minimum balance or purchase minimum for fund shares offered through this prospectus.

Price to Buy

The price to buy one share is its NAV. Shares are sold without a sales charge.

Shares will be bought at the NAV next calculated after an order is received in proper form.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently, including, if applicable, periods when redemptions are suspended.

Under applicable anti-money laundering rules and other regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Selling Shares

The price to sell one share is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form.

Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect the fund.

See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.

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

• Redemption proceeds may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.

• 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 the Adviser determines it is in the best interests of the fund.

• Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.
• The Board of Trustees may determine that it would not be in a fund's best interests to continue operating under circumstances listed in Rule 22e-3 under the Investment Company Act of 1940, at which point the fund may permanently suspend redemptions and liquidate.

Policies Concerning the Redemption of Fund Shares

A fund typically expects to pay redemption proceeds on the next business day (or earlier to the extent a fund offers a same day settlement feature) following receipt of a redemption order in proper form.

As noted elsewhere, payment of redemption proceeds may take longer than the time a fund typically expects and may take up to seven days from the date of receipt of the redemption order as permitted by applicable law.

Redemption Methods Available. Generally a fund expects to pay redemption proceeds in cash. To do so, a fund typically expects to satisfy redemption requests either by using available cash (or cash equivalents) or by selling portfolio securities. On a less regular basis, a fund may also satisfy redemption requests by utilizing one or more of the following sources, if permitted: borrowing from another Fidelity® fund; drawing on an available line or lines of credit from a bank or banks; or using reverse repurchase agreements (if authorized). These methods may be used during both normal and stressed market conditions.

In addition to paying redemption proceeds in cash, a fund reserves the right to pay part or all of your redemption proceeds in readily marketable securities instead of cash (redemption in-kind). Redemption in-kind proceeds will typically be made by delivering the selected securities to the redeeming shareholder within seven days after the receipt of the redemption order in proper form by a fund.

Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations. In addition, the fund reserves the right to involuntarily redeem an account in the case of: (i) actual or suspected threatening conduct or actual or suspected fraudulent, illegal or suspicious activity by the account owner or any other individual associated with the account; or (ii) the failure of the account owner to provide information to the fund related to opening the accounts. Your shares will be sold at the NAV, minus any applicable shareholder fees, calculated on the day Fidelity closes your fund position.

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

Dividends and Capital Gain Distributions

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

Distributions from a money market fund consist primarily of dividends. A money market fund normally declares dividends daily and pays them monthly.

Earning Dividends 

The fund processes purchase and redemption requests only on days it is open for business. 

Shares purchased by a wire order prior to 2:00 p.m. Eastern time, with receipt of the wire in proper form before the close of the Federal Reserve Wire System on that day, generally begin to earn dividends on the day of purchase.

Shares purchased by all other orders generally begin to earn dividends on the first business day following the day of purchase. 

Shares redeemed by a wire order prior to 2:00 p.m. Eastern time generally earn dividends through the day prior to the day of redemption.

Shares redeemed by all other orders generally earn dividends until, but not including, the next business day following the day of redemption. 

Money market funds that allow wire purchases reserve the right to change the time of day by which wire purchase and redemption orders for shares must be placed for purposes of earning dividends. 

Distribution Options

When you open an account, specify how you want to receive your distributions. The following distribution options are available: 

• 1. Reinvestment Option. 

Any dividends and capital gain distributions will be automatically reinvested in additional shares.

Tax Consequences

As with any investment, your investment in the fund could have tax consequences for you (for non-retirement accounts).

Distributions you receive from the fund are subject to federal income tax, and may also be subject to state or local taxes. A portion of the fund's dividends may be exempt from state and local taxation to the extent that they are derived from certain U.S. Government securities and meet certain requirements.

For federal tax purposes, certain distributions, including dividends and distributions of short-term capital gains, are taxable to you as ordinary income, while certain distributions, including distributions of long-term capital gains, if any, are taxable to you generally as capital gains. Because the fund's income is primarily derived from interest, dividends from the fund generally will not qualify for the long-term capital gains tax rates available to individuals. 

Any taxable distributions you receive from the fund will normally be taxable to you when you receive them, regardless of your distribution option.

If you are a non-U.S. shareholder, fund distributions allocable from U.S.-source interest income or from capital gains will generally be free from U.S. federal withholding tax, but dividends from other sources may be subject to U.S. withholding tax under applicable rules.

Fund Services

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

Adviser

FMR. The Adviser is the fund's manager. The address of the Adviser is 245 Summer Street, Boston, Massachusetts 02210.

As of December 31, 2023, the Adviser had approximately $3.9 trillion in discretionary assets under management, and approximately $4.9 trillion when combined with all of its affiliates' assets under management.

As the manager, the Adviser has overall responsibility for directing the fund's investments and handling its business affairs.

FMR Japan may provide investment research and advice on issuers based outside the United States and may also provide investment advisory services for the fund.

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 fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any fund. 

Advisory Fee(s)

Each class of the fund pays an all-inclusive management fee to the Adviser.

A different all-inclusive management fee rate is applicable to each class of the fund. The difference between classes is the result of separate arrangements for class level services and/or waivers of certain expenses. It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class.

The all-inclusive management fee is calculated and paid to the Adviser each month. Out of each class's all-inclusive management fee, the Adviser or an affiliate pays all expenses of managing and operating the fund, with limited exceptions.

The annual management fee rate, as a percentage of the class's average net assets, is shown in the following table:

Fund	Class OUS
Fidelity® Treasury Only Money Market Fund	0.37%

The Adviser pays FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited for providing sub-advisory services.

The basis for the Board of Trustees approving the management contract and sub-advisory agreements for the fund is available in the fund's Form N-CSRS report for the fiscal period ended October 31, 2024.

From time to time, the Adviser or its affiliates may agree to reimburse or waive certain fund expenses while retaining the ability to be repaid if expenses fall below the specified limit prior to the end of the fiscal year.

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

The fund is composed of multiple classes of shares. All classes of the fund have a common investment objective and investment portfolio.

FDC distributes Class OUS shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses, and compensation for services intended to result in the sale of Class OUS shares.

These payments are described in more detail in this section and in the Statement of Additional Information (SAI).

Distribution and Service Plan(s)

Class OUS of the fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act) that recognizes that the Adviser 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 Class OUS shares and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class OUS.

If payments made by the Adviser to FDC or to intermediaries under the Distribution and Service Plan were considered to be paid out of the class'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.

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 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 fund or FDC. This prospectus and the related SAI do not constitute an offer by the fund or by FDC to sell shares of the fund to, or to buy shares of the fund from, any person to whom it is unlawful to make such offer.

Appendix

Financial Highlights

Financial Highlights are intended to help you understand the financial history of fund shares for the past 5 years (or, if shorter, the period of operations). Certain information reflects financial results for a single share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in shares (assuming reinvestment of all dividends and distributions). Because Class OUS shares have not commenced operations as of the end of the fund's fiscal year, financial highlights are not available. The annual information has been audited by [_____], independent registered public accounting firm, whose report, along with fund financial statements, is included in the annual report.

TABLE OF CONTENTS

INVESTMENT POLICIES AND LIMITATIONS 

The following policies and limitations supplement those set forth in the prospectus. Unless otherwise noted, whenever an investment policy or limitation states a maximum percentage of the fund's assets that may be invested in any security or other asset, or sets forth a policy regarding quality standards, such standard or percentage limitation will be determined immediately after and as a result of the fund's acquisition of such security or other asset. Accordingly, any subsequent change in values, net assets, or other circumstances will not be considered when determining whether the investment complies with the fund's investment policies and limitations.

The fund's fundamental investment policies and limitations cannot be changed without approval by a "majority of the outstanding voting securities" (as defined in the Investment Company Act of 1940 (1940 Act)) of the fund. However, except for the fundamental investment limitations listed below, the investment policies and limitations described in this Statement of Additional Information (SAI) are not fundamental and may be changed without shareholder approval.

The following are the fund's fundamental investment limitations set forth in their entirety.

Diversification

The fund may not purchase the securities of any issuer, if, as a result, the fund would not comply with any applicable diversification requirements for a money market fund under the Investment Company Act of 1940 and the rules thereunder, as such may be amended from time to time.

Senior Securities

The fund may not issue senior securities, except in connection with the insurance program established by the fund pursuant to an exemptive order issued by the Securities and Exchange Commission or as otherwise permitted under the Investment Company Act of 1940.

Short Sales

The fund may not sell securities short, unless it owns, or by virtue of ownership of other securities has the right to obtain, securities equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts are not deemed to constitute short sales.

Margin Purchases

The fund may not purchase securities on margin, except that the fund may obtain such short-term credits as are necessary for the clearance of transactions, and provided that the fund may make initial and variation margin payments in connection with transactions in futures contracts and options on futures contracts.

Borrowing

The fund may not borrow money, except that the fund may (i) borrow money for temporary or emergency purposes (not for leveraging or investment) and (ii) engage in reverse repurchase agreements for any purpose; provided that (i) and (ii) in combination do not exceed 33 1/3% of the fund's total assets (including the amount borrowed) less liabilities (other than borrowings). Any borrowings that come to exceed this amount will be reduced within three days (not including Sundays and holidays) to the extent necessary to comply with the 33 1/3% limitation.

Underwriting

The fund may not underwrite securities issued by others, except to the extent that the fund may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of restricted securities or in connection with investments in other investment companies.

Concentration

The fund may not purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities) if, as a result, more than 25% of the fund's total assets would be invested in the securities of companies whose principal business activities are in the same industry.

For purposes of the fund's concentration limitation discussed above, FMR may analyze the characteristics of a particular issuer and security and assign an industry or sector classification consistent with those characteristics in the event that the third-party classification provider used by FMR does not assign a classification.

Real Estate

The fund may not purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the fund from investing in securities or other instruments backed by real estate or securities of companies engaged in the real estate business).

Commodities

The fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities (but this shall not prevent the fund from purchasing and selling futures contracts).

Loans

The fund may not lend any security or make any other loan if, as a result, more than 33 1/3% of its total assets would be lent to other parties, but this limitation does not apply to purchases of debt securities or to repurchase agreements, or to acquisitions of loans, loan participations or other forms of debt instruments.

Pooled Funds

The fund may, notwithstanding any other fundamental investment policy or limitation, invest all of its assets in the securities of a single open-end management investment company managed by Fidelity Management & Research Company LLC (FMR) or an affiliate or successor with substantially the same fundamental investment objective, policies, and limitations as the fund.

The following investment limitations are not fundamental and may be changed without shareholder approval.

Diversification

The fund does not currently intend to purchase a security (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities, or securities of other money market funds) if, as a result, more than 5% of its total assets would be invested in securities of a single issuer; provided that the fund may invest up to 25% of its total assets in the first tier securities of a single issuer for up to three business days.

For purposes of the fund's diversification limitation discussed above, certain securities subject to guarantees (including insurance, letters of credit and demand features) are not considered securities of their issuer, but are subject to separate diversification requirements, in accordance with industry standard requirements for money market funds.

Borrowing

The fund may borrow money only (a) from a bank or from a registered investment company or portfolio for which FMR or an affiliate serves as investment adviser or (b) by engaging in reverse repurchase agreements with any party.

For purposes of the fund's borrowing policy as applicable to reverse repurchase agreements, the fund will only engage in reverse repurchase agreements with a bank.

Illiquid Securities

The fund does not currently intend to purchase any security if, as a result, more than 5% of its total assets would be invested in securities that are deemed to be illiquid because they are subject to legal or contractual restrictions on resale or because they cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to it by the fund.

For purposes of the fund's illiquid securities limitation discussed above, if through a change in values, net assets, or other circumstances, the fund were in a position where more than 5% of its total assets were invested in illiquid securities, it would consider appropriate steps to protect liquidity.

Loans

The fund does not currently intend to make loans, but this limitation does not apply to purchases of debt securities or to repurchase agreements.

Pooled Funds

The fund does not currently intend to invest all of its assets in the securities of a single open-end management investment company managed by FMR or an affiliate or successor with substantially the same fundamental investment objective, policies, and limitations as the fund.

In addition to the fund's fundamental and non-fundamental investment limitations discussed above:

In order to qualify as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986, as amended, the fund currently intends to comply with certain diversification limits imposed by Subchapter M.

The following pages contain more detailed information about types of instruments in which the fund may invest, techniques the fund's adviser (or a sub-adviser) may employ in pursuit of the fund's investment objective, and a summary of related risks. The fund's adviser (or a sub-adviser) may not buy all of these instruments or use all of these techniques unless it believes that doing so will help the fund achieve its goal. However, the fund's adviser (or a sub-adviser) is not required to buy any particular instrument or use any particular technique even if to do so might benefit the fund.

On the following pages in this section titled "Investment Policies and Limitations," and except as otherwise indicated, references to "an adviser" or "the adviser" may relate to the fund's adviser or a sub-adviser, as applicable.

Affiliated Bank Transactions. A Fidelity® fund may engage in transactions with financial institutions that are, or may be considered to be, "affiliated persons" of the fund under the 1940 Act. These transactions may involve repurchase agreements with custodian banks; short-term obligations of, and repurchase agreements with, the 50 largest U.S. banks (measured by deposits); municipal securities; U.S. Government securities with affiliated financial institutions that are primary dealers in these securities; short-term currency transactions; and short-term borrowings. In accordance with exemptive orders issued by the Securities and Exchange Commission (SEC), the Board of Trustees has established and periodically reviews procedures applicable to transactions involving affiliated financial institutions.

Borrowing. Fidelity® Treasury Only Money Market Fund may make additional investments while borrowings are outstanding.

Cash Management. A fund may hold uninvested cash.

Central Funds are special types of investment vehicles created by Fidelity for use by the Fidelity® funds and other advisory clients. Central funds are used to invest in particular security types or investment disciplines, or for cash management. Central funds incur certain costs related to their investment activity (such as custodial fees and expenses), but generally do not pay management fees. The investment results of the portions of a Fidelity® fund's assets invested in the Central funds will be based upon the investment results of those funds.

Commodity Futures Trading Commission (CFTC) Notice of Exclusion. The Adviser, on behalf of the Fidelity® fund to which this SAI relates, has filed with the National Futures Association a notice claiming an exclusion from the definition of the term "commodity pool operator" (CPO) under the Commodity Exchange Act, as amended, and the rules of the CFTC promulgated thereunder, with respect to the fund's operation. Accordingly, neither a fund nor its adviser is subject to registration or regulation as a commodity pool or a CPO. As of the date of this SAI, the adviser does not expect to register as a CPO of the fund. However, there is no certainty that a fund or its adviser will be able to rely on an exclusion in the future as the fund's investments change over time. A fund may determine not to use investment strategies that trigger additional CFTC regulation or may determine to operate subject to CFTC regulation, if applicable. If a fund or its adviser operates subject to CFTC regulation, it may incur additional expenses.

Disruption to Financial Markets and Related Government Intervention. Economic downturns can trigger various economic, legal, budgetary, tax, and regulatory reforms across the globe. Instability in the financial markets in the wake of events such as the 2008 economic downturn led the U.S. Government and other governments to take a number of then-unprecedented actions designed to support certain financial institutions and segments of the financial markets that experienced extreme volatility, and in some cases, a lack of liquidity. Federal, state, local, foreign, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the regulation of the instruments in which a fund invests, or the issuers of such instruments, in ways that are unforeseeable. Reforms may also change the way in which a fund is regulated and could limit or preclude a fund's ability to achieve its investment objective or engage in certain strategies. Also, while reforms generally are intended to strengthen markets, systems, and public finances, they could affect fund expenses and the value of fund investments in unpredictable ways.

Similarly, widespread disease including pandemics and epidemics, and natural or environmental disasters, such as earthquakes, droughts, fires, floods, hurricanes, tsunamis and climate-related phenomena generally, have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of a fund's investments. Economies and financial markets throughout the world have become increasingly interconnected, which increases the likelihood that events or conditions in one region or country will adversely affect markets or issuers in other regions or countries, including the United States. Additionally, market disruptions may result in increased market volatility; regulatory trading halts; closure of domestic or foreign exchanges, markets, or governments; or market participants operating pursuant to business continuity plans for indeterminate periods of time. Further, market disruptions can (i) prevent a fund from executing advantageous investment decisions in a timely manner, (ii) negatively impact a fund's ability to achieve its investment objective, and (iii) may exacerbate the risks discussed elsewhere in a fund's registration statement, including political, social, and economic risks.

The value of a fund's portfolio is also generally subject to the risk of future local, national, or global economic or natural disturbances based on unknown weaknesses in the markets in which a fund invests. In the event of such a disturbance, the issuers of securities held by a fund may experience significant declines in the value of their assets and even cease operations, or may receive government assistance accompanied by increased restrictions on their business operations or other government intervention. In addition, it remains uncertain that the U.S. Government or foreign governments will intervene in response to current or future market disturbances and the effect of any such future intervention cannot be predicted.

Funds of Funds and Other Large Shareholders. Certain Fidelity® funds and accounts (including funds of funds) invest in other funds ("underlying funds") and, as a result, may at times have substantial investments in one or more underlying funds.

An underlying fund may experience large redemptions or investments due to transactions in its shares by funds of funds, other large shareholders, or similarly managed accounts. While it is impossible to predict the overall effect of these transactions over time, there could be an adverse impact on an underlying fund's performance. In the event of such redemptions or investments, an underlying fund could be required to sell securities or to invest cash at a time when it may not otherwise desire to do so. Such transactions may increase an underlying fund's brokerage and/or other transaction costs and affect the liquidity of a fund's portfolio. In addition, when funds of funds or other investors own a substantial portion of an underlying fund's shares, a large redemption by such an investor could cause actual expenses to increase, or could result in the underlying fund's current expenses being allocated over a smaller asset base, leading to an increase in the underlying fund's expense ratio. Redemptions of underlying fund shares could also accelerate the realization of taxable capital gains in the fund if sales of securities result in capital gains. The impact of these transactions is likely to be greater when a fund of funds or other significant investor purchases, redeems, or owns a substantial portion of the underlying fund's shares.

When possible, Fidelity will consider how to minimize these potential adverse effects, and may take such actions as it deems appropriate to address potential adverse effects, including redemption of shares in-kind rather than in cash or carrying out the transactions over a period of time, although there can be no assurance that such actions will be successful. A high volume of redemption requests can impact an underlying fund the same way as the transactions of a single shareholder with substantial investments. As an additional safeguard, Fidelity® fund of funds may manage the placement of their redemption requests in a manner designed to minimize the impact of such requests on the day-to-day operations of the underlying funds in which they invest. This may involve, for example, redeeming its shares of an underlying fund gradually over time.

Illiquid Investments means any investment that cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Difficulty in selling or disposing of illiquid investments may result in a loss or may be costly to a fund. Illiquid securities may include (1) repurchase agreements maturing in more than seven days without demand/redemption features, (2) over-the-counter (OTC) options and certain other derivatives, (3) private placements, (4) securities traded on markets and exchanges with structural constraints, and (5) loan participations.

Under the supervision of the Board of Trustees, a Fidelity® fund's adviser classifies the liquidity of a fund's investments and monitors the extent of a fund's illiquid investments.

Various market, trading and investment-specific factors may be considered in determining the liquidity of a fund's investments including, but not limited to (1) the existence of an active trading market, (2) the nature of the security and the market in which it trades, (3) the number, diversity, and quality of dealers and prospective purchasers in the marketplace, (4) the frequency, volume, and volatility of trade and price quotations, (5) bid-ask spreads, (6) dates of issuance and maturity, (7) demand, put or tender features, and (8) restrictions on trading or transferring the investment.

Fidelity classifies certain investments as illiquid based upon these criteria. Fidelity also monitors for certain market, trading and investment-specific events that may cause Fidelity to re-evaluate an investment's liquidity status and may lead to an investment being classified as illiquid. In addition, Fidelity uses a third-party to assist with the liquidity classifications of the fund's investments, which includes calculating the time to sell and settle a specified size position in a particular investment without the sale significantly changing the market value of the investment.

Increasing Government Debt. The total public debt of the United States and other countries around the globe as a percent of gross domestic product has, at times, grown rapidly. Although high debt levels do not necessarily indicate or cause economic problems, they may create certain systemic risks if sound debt management practices are not implemented.

A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and cause a country to sell additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that a government will not be able to make principal or interest payments when they are due. In the worst case, unsustainable debt levels can decline the valuation of currencies, and can prevent a government from implementing effective counter-cyclical fiscal policy in economic downturns.

Rating services have, in the past, lowered their long-term sovereign credit rating on the United States. The market prices and yields of securities supported by the full faith and credit of the U.S. Government may be adversely affected by rating services' decisions to downgrade the long-term sovereign credit rating of the United States.

Insolvency of Issuers, Counterparties, and Intermediaries. Issuers of fund portfolio securities or counterparties to fund transactions that become insolvent or declare bankruptcy can pose special investment risks. In each circumstance, risk of loss, valuation uncertainty, increased illiquidity, and other unpredictable occurrences may negatively impact an investment. Each of these risks may be amplified in foreign markets, where security trading, settlement, and custodial practices can be less developed than those in the U.S. markets, and bankruptcy laws differ from those of the U.S.

As a general matter, if the issuer of a fund portfolio security is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock have priority over the claims of common stock owners. These events can negatively impact the value of the issuer's securities and the results of related proceedings can be unpredictable.

If a counterparty to a fund transaction becomes insolvent, the fund may be limited in its ability to exercise rights to obtain the return of related fund assets or in exercising other rights against the counterparty. In addition, insolvency and liquidation proceedings take time to resolve, which can limit or preclude a fund's ability to terminate a transaction or obtain related assets or collateral in a timely fashion. Uncertainty may also arise upon the insolvency of an intermediary with which a fund has pending transactions. If an intermediary becomes insolvent, while securities positions and other holdings may be protected by U.S. or foreign laws, it is sometimes difficult to determine whether these protections are available to specific trades based on the circumstances. Receiving the benefit of these protections can also take time to resolve, which may result in illiquid positions.

Interfund Borrowing and Lending Program. Pursuant to an exemptive order issued by the SEC, a Fidelity® fund may lend money to, and borrow money from, other funds advised by FMR or its affiliates. Fidelity® Treasury Only Money Market Fund currently intends to participate in this program only as a borrower. A Fidelity® fund will borrow through the program only when the costs are equal to or lower than the costs of bank loans. A Fidelity® fund will lend through the program only when the returns are higher than those available from an investment in repurchase agreements. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. Loans may be called on one day's notice. A Fidelity® fund may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs.

Low or Negative Yielding Securities. During periods of very low or negative interest rates, a fund may be unable to maintain positive returns. Interest rates in the U.S. and many parts of the world, including Japan and some European countries, have recently been at or near historically low levels. Japan and those European countries have, from time to time, experienced negative interest rates on certain fixed income instruments. Very low or negative interest rates may magnify interest rate risk for the markets as a whole and for the funds. Changing interest rates, including rates that fall below zero, may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance to the extent a fund is exposed to such interest rates.

Put Features entitle the holder to sell a security back to the issuer at any time or at specified intervals. In exchange for this benefit, a fund may accept a lower interest rate. Securities with put features are subject to the risk that the put provider is unable to honor the put feature (purchase the security).

Repurchase Agreements involve an agreement to purchase a security and to sell that security back to the original seller at an agreed-upon price. The resale price reflects the purchase price plus an agreed-upon incremental amount which is unrelated to the coupon rate or maturity of the purchased security. As protection against the risk that the original seller will not fulfill its obligation, the securities are held in a separate account at a bank, marked-to-market daily, and maintained at a value at least equal to the sale price plus the accrued incremental amount. The value of the security purchased may be more or less than the price at which the counterparty has agreed to purchase the security. In addition, delays or losses could result if the other party to the agreement defaults or becomes insolvent. A fund may be limited in its ability to exercise its right to liquidate assets related to a repurchase agreement with an insolvent counterparty. A Fidelity® fund may engage in repurchase agreement transactions with parties whose creditworthiness has been reviewed and found satisfactory by the fund's adviser.

Restricted Securities (including Private Placements) are subject to legal restrictions on their sale. Difficulty in selling securities may result in a loss or be costly to a fund. Restricted securities, including private placements of private and public companies, generally can be sold in privately negotiated transactions, pursuant to an exemption from registration under the Securities Act of 1933 (1933 Act), or in a registered public offering. Where registration is required, the holder of a registered security may be obligated to pay all or part of the registration expense and a considerable period may elapse between the time it decides to seek registration and the time it may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the holder might obtain a less favorable price than prevailed when it decided to seek registration of the security.

Reverse Repurchase Agreements. In a reverse repurchase agreement, a fund sells a security to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase that security at an agreed-upon price and time. A Fidelity® fund may enter into reverse repurchase agreements with parties whose creditworthiness has been reviewed and found satisfactory by the fund's adviser. Such transactions may increase fluctuations in the market value of a fund's assets and, if applicable, a fund's yield, and may be viewed as a form of leverage. A money market fund may enter into reverse repurchase agreements with banks and needs to aggregate the amount of indebtedness associated with its reverse repurchase agreements with the aggregate amount of any other senior securities representing indebtedness (e.g., borrowings, if applicable) when calculating the fund's asset coverage ratio. 

SEC Rule 18f-4.In October 2020, the SEC adopted a final rule related to the use of derivatives, reverse repurchase agreements and certain other transactions by registered investment companies. A money market fund cannot rely on the rule to use such instruments, with a limited exception for certain investments in when-issued, forward-settling and non-standard settlement cycle securities transactions. Under Rule 18f-4, a money market fund will only be permitted to invest in a security on a when-issued or forward-settling basis, or with a non-standard settlement cycle, and the transaction will be deemed not to involve a senior security (as defined under Section 18(g) of the 1940 Act), provided that (i) the fund intends to physically settle the transaction and (ii) the transaction will settle within 35 days of its trade date. 

Securities of Other Investment Companies, including shares of closed-end investment companies (which include business development companies (BDCs)), unit investment trusts, and open-end investment companies such as mutual funds and ETFs, represent interests in professionally managed portfolios that may invest in any type of instrument. Investing in other investment companies (including investment companies managed by the Adviser and its affiliates) involves substantially the same risks as investing directly in the underlying instruments, but may involve additional expenses at the underlying investment company-level, such as portfolio management fees and operating expenses, unless such fees have been waived by the Adviser. Fees and expenses incurred indirectly by a fund as a result of its investment in shares of one or more other investment companies generally are referred to as "acquired fund fees and expenses" and may appear as a separate line item in a fund's prospectus fee table. For certain investment companies, such as BDCs, these expenses may be significant. Certain types of investment companies, such as closed-end investment companies, issue a fixed number of shares that trade on a stock exchange or over-the-counter at a premium or a discount to their net asset value per share (NAV). Others are continuously offered at NAV, but may also be traded in the secondary market. Similarly, ETFs trade on a securities exchange and may trade at a premium or a discount to their NAV.

A fund's ability to invest in securities of other investment companies may be limited by federal securities laws. To the extent a fund acquires securities issued by unaffiliated investment companies, the Adviser's access to information regarding such underlying fund's portfolio may be limited and subject to such fund's policies regarding disclosure of fund holdings.

Stripped Securities are the separate income or principal components of a debt security. The risks associated with stripped securities are similar to those of other money market securities, although stripped securities may be more volatile. U.S. Treasury securities that have been stripped by a Federal Reserve Bank are obligations issued by the U.S. Treasury. 

Temporary Defensive Policies. Fidelity® Treasury Only Money Market Fund reserves the right to hold a substantial amount of uninvested cash for temporary, defensive purposes.

Transfer Agent Bank Accounts. Proceeds from shareholder purchases of a Fidelity® fund may pass through a series of demand deposit bank accounts before being held at the fund's custodian. Redemption proceeds may pass from the custodian to the shareholder through a similar series of bank accounts.

If a bank account is registered to the transfer agent or an affiliate, who acts as an agent for the fund when opening, closing, and conducting business in the bank account, the transfer agent or an affiliate may invest overnight balances in the account in repurchase agreements or money market funds. Any balances that are not invested in repurchase agreements or money market funds remain in the bank account overnight. Any risks associated with such an account are investment risks of the fund. The fund faces the risk of loss of these balances if the bank becomes insolvent.

Variable and Floating Rate Securities provide for periodic adjustments in the interest rate paid on the security. Variable rate securities provide for a specified periodic adjustment in the interest rate, while floating rate securities have interest rates that change whenever there is a change in a designated benchmark rate or the issuer's credit quality, sometimes subject to a cap or floor on such rate. Some variable or floating rate securities are structured with put features that permit holders to demand payment of the unpaid principal balance plus accrued interest from the issuers or certain financial intermediaries.

In addition to other interbank offered rates (IBORs), the London Interbank Offered Rate (LIBOR), which was calculated based on the rate of interest offered on short-term interbank deposits, had historically been the most common benchmark rate for floating rate securities. After the global financial crisis, regulators globally determined that existing interest rate benchmarks should be reformed based on concerns that LIBOR and other IBORs were susceptible to manipulation. Replacement rates that have been identified include the Secured Overnight Financing Rate (SOFR, which is intended to replace U.S. dollar LIBOR and measures the cost of U.S. dollar overnight borrowings collateralized by treasuries) and the Sterling Overnight Index Average rate (SONIA, which is intended to replace pound sterling LIBOR and measures the overnight interest rate paid by banks in the sterling market). Markets are slowly developing in response to these new rates. As a result of the benchmark reforms, publication of all LIBOR settings has ceased. Although the transition process away from IBORs for most instruments has been completed, any potential effects of a transition away from the IBORs on a fund and the financial instruments in which it invests can be difficult to ascertain, and may depend on factors that include, but are not limited to: (i) existing fallback or termination provisions in individual contracts; (ii) the effect of new legislation relating to the discontinuation of LIBOR and the use of replacement rates, and (iii) whether, how, and when industry participants develop and adopt new reference rates and fallbacks for both legacy and new products and instruments. Moreover, certain aspects of the transition from IBORs will rely on the actions of third-party market participants, such as clearing houses, trustees, administrative agents, asset servicers and certain service providers; the Adviser cannot guarantee the performance of such market participants and any failure on the part of such market participants to manage their part of the IBOR transition could impact a fund. Such transition may result in a reduction in the value of IBOR-based (or formerly IBOR-based) instruments held by a fund, a reduction in the effectiveness of certain hedging transactions and increased illiquidity and volatility in markets that currently rely or previously relied on an IBOR to determine interest rates, any of which could adversely impact the fund's performance.

When-Issued and Forward Purchase or Sale Transactions involve a commitment to purchase or sell specific securities at a predetermined price or yield in which payment and delivery take place after the customary settlement period for that type of security. Typically, no interest accrues to the purchaser until the security is delivered.

When purchasing securities pursuant to one of these transactions, the purchaser assumes the rights and risks of ownership, including the risks of price and yield fluctuations and the risk that the security will not be issued as anticipated. Because payment for the securities is not required until the delivery date, these risks are in addition to the risks associated with a fund's investments. If a fund remains substantially fully invested at a time when a purchase is outstanding, the purchases may result in a form of leverage. When a fund has sold a security pursuant to one of these transactions, the fund does not participate in further gains or losses with respect to the security. If the other party to a delayed-delivery transaction fails to deliver or pay for the securities, a fund could miss a favorable price or yield opportunity or suffer a loss.

A fund may renegotiate a when-issued or forward transaction and may sell the underlying securities before delivery, which may result in capital gains or losses for the fund.

In addition to the investment policies and limitations discussed above, a fund is subject to the additional operational risk discussed below.

Considerations Regarding Cybersecurity. With the increased use of technologies such as the Internet to conduct business, a fund's service providers are susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events and may arise from external or internal sources. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through "hacking" or malicious software coding) for purposes of misappropriating assets or sensitive information; corrupting data, equipment or systems; or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber incidents affecting a fund's manager, any sub-adviser and other service providers (including, but not limited to, fund accountants, custodians, transfer agents and financial intermediaries) have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with a fund's ability to calculate its NAV, impediments to trading, the inability of fund shareholders to transact business, destruction to equipment and systems, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. Similar adverse consequences could result from cyber incidents affecting issuers of securities in which a fund invests, counterparties with which a fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions (including financial intermediaries and service providers for fund shareholders) and other parties. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future.

While a fund's service providers have established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, a fund cannot control the cyber security plans and systems put in place by its service providers or any other third parties whose operations may affect a fund or its shareholders. A fund and its shareholders could be negatively impacted as a result.

PORTFOLIO TRANSACTIONS

Orders for the purchase or sale of portfolio securities are placed on behalf of the fund by Fidelity Management & Research Company LLC (FMR or the Adviser) pursuant to authority contained in the management contract.  

To the extent that the Adviser grants investment management authority to a sub-adviser (see the section entitled "Management Contract"), that sub-adviser is authorized to provide the services described in the respective sub-advisory agreement, and in accordance with the policies described in this section. Furthermore, the sub-adviser's trading and associated policies, which may differ from the Adviser's policies, may apply to that fund, subject to applicable law.

The Adviser or a sub-adviser may be responsible for the placement of portfolio securities transactions for other investment companies and investment accounts for which it has or its affiliates have investment discretion.

The fund will not incur any commissions or sales charges when it invests in shares of certain pooled investment vehicles (including any underlying Central funds), but it may incur such costs when it invests directly in other types of securities.

Purchases and sales of equity securities on a securities exchange or OTC are effected through brokers who receive compensation for their services. Generally, compensation relating to securities traded on foreign exchanges will be higher than compensation relating to securities traded on U.S. exchanges and may not be subject to negotiation. Compensation may also be paid in connection with principal transactions (in both OTC securities and securities listed on an exchange) and agency OTC transactions executed with an electronic communications network (ECN) or an alternative trading system. Equity securities may be purchased from underwriters at prices that include underwriting fees.

Purchases and sales of fixed-income securities are generally made with an issuer or a primary market-maker acting as principal. Although there is no stated brokerage commission paid by the fund for any fixed-income security, the price paid by the fund to an underwriter includes the disclosed underwriting fee and prices in secondary trades usually include an undisclosed dealer commission or markup reflecting the spread between the bid and ask prices of the fixed-income security. New issues of equity and fixed-income securities may also be purchased in underwritten fixed price offerings. 

The Trustees of the fund periodically review the Adviser's performance of its responsibilities in connection with the placement of portfolio securities transactions on behalf of the fund. The Trustees also review the compensation paid by the fund over representative periods of time to determine if it was reasonable in relation to the benefits to the fund.

The Selection of Securities Brokers and Dealers

The Adviser or its affiliates generally have authority to select brokers (whether acting as a broker or a dealer) to place or execute the fund's portfolio securities transactions. In selecting brokers, including affiliates of the Adviser, to execute the fund's portfolio securities transactions, the Adviser or its affiliates consider the factors they deem relevant in the context of a particular trade and in regard to the Adviser's or its affiliates' overall responsibilities with respect to the fund and other investment accounts, including any instructions from the fund's portfolio manager, which may emphasize, for example, speed of execution over other factors. Based on the factors considered, the Adviser or its affiliates may choose to execute an order using ECNs, including broker-sponsored algorithms, internal crossing, or by verbally working an order with one or more brokers. Other possibly relevant factors include, but are not limited to, the following: price; costs; the size, nature and type of the order; the speed of execution; financial condition and reputation of the broker; broker specific considerations (e.g., not all brokers are able to execute all types of trades); broker willingness to commit capital; the nature and characteristics of the markets in which the security is traded; the trader's assessment of whether and how closely the broker likely will follow the trader's instructions to the broker; confidentiality and the potential for information leakage; the nature or existence of post-trade clearing, settlement, custody and currency convertibility mechanisms; and the provision of additional brokerage and research products and services, if applicable and where allowed by law.

In seeking best execution for portfolio securities transactions, the Adviser or its affiliates may from time to time select a broker that uses a trading method, including algorithmic trading, for which the broker charges a higher commission than its lowest available commission rate. The Adviser or its affiliates also may select a broker that charges more than the lowest commission rate available from another broker. Occasionally the Adviser or its affiliates execute an entire securities transaction with a broker and allocate all or a portion of the transaction and/or related commissions to a second broker where a client does not permit trading with an affiliate of the Adviser or in other limited situations. In those situations, the commission rate paid to the second broker may be higher than the commission rate paid to the executing broker. For futures transactions, the selection of a futures commission merchant is generally based on the overall quality of execution and other services provided by the futures commission merchant. The Adviser or its affiliates execute futures transactions verbally and electronically.

The Acquisition of Brokerage and Research Products and Services

Brokers (who are not affiliates of the Adviser) that execute transactions for a fund managed outside of the European Union or the United Kingdom may receive higher compensation from the fund than other brokers might have charged the fund, in recognition of the value of the brokerage or research products and services they provide to the Adviser or its affiliates.

Research Products and Services. These products and services may include, when permissible under applicable law, but are not limited to: economic, industry, company, municipal, sovereign (U.S. and non-U.S.), legal, or political research reports; market color; company meeting facilitation; compilation of securities prices, earnings, dividends and similar data; quotation services, data, information and other services; analytical computer software and services; and investment recommendations. In addition to receiving brokerage and research products and services via written reports and computer-delivered services, such reports may also be provided by telephone and in video and in-person meetings with securities analysts, corporate and industry spokespersons, economists, academicians and government representatives and others with relevant professional expertise. The Adviser or its affiliates may request that a broker provide a specific proprietary or third-party product or service. Some of these brokerage and research products and services supplement the Adviser's or its affiliates' own research activities in providing investment advice to the fund.

Execution Services. In addition, when permissible under applicable law, brokerage and research products and services include those that assist in the execution, clearing, and settlement of securities transactions, as well as other incidental functions (including, but not limited to, communication services related to trade execution, order routing and algorithmic trading, post-trade matching, exchange of messages among brokers or dealers, custodians and institutions, and the use of electronic confirmation and affirmation of institutional trades).

Mixed-Use Products and Services. Although the Adviser or its affiliates do not use fund commissions to pay for products or services that do not qualify as brokerage and research products and services or eligible external research under MiFID II and FCA regulations (as defined below), where allowed by applicable law, they, at times, will use commission dollars to obtain certain products or services that are not used exclusively in the Adviser's or its affiliates' investment decision-making process (mixed-use products or services). In those circumstances, the Adviser or its affiliates will make a good faith judgment to evaluate the various benefits and uses to which they intend to put the mixed-use product or service, and will pay for that portion of the mixed-use product or service that does not qualify as brokerage and research products and services or eligible external research with their own resources (referred to as "hard dollars").

Benefit to the Adviser. The Adviser's or its affiliates' expenses likely would be increased if they attempted to generate these additional brokerage and research products and services through their own efforts, or if they paid for these brokerage and research products or services with their own resources. Therefore, an economic incentive exists for the Adviser and/or its affiliates to select or recommend a broker-dealer based on its interest in receiving the brokerage and research products and services, rather than on the Adviser's or its affiliates' funds interest in receiving most favorable execution. The Adviser and its affiliates manage the receipt of brokerage and research products and services and the potential for conflicts through its Commission Uses Program. The Commission Uses Program effectively "unbundles" commissions paid to brokers who provide brokerage and research products and services, i.e., commissions consist of an execution commission, which covers the execution of the trade (including clearance and settlement), and a research charge, which is used to cover brokerage and research products and services. Those brokers have client commission arrangements (each a CCA) in place with the Adviser and its affiliates (each of those brokers referred to as CCA brokers). In selecting brokers for executing transactions on behalf of the fund, the trading desks through which the Adviser or its affiliates may execute trades are instructed to execute portfolio transactions on behalf of the fund based on the quality of execution without any consideration of brokerage and research products and services the CCA broker provides. Commissions paid to a CCA broker include both an execution commission and a research charge, and while the CCA broker receives the entire commission, it retains the execution commission and either credits or transmits the research portion (also known as "soft dollars") to a CCA pool maintained by each CCA broker. Soft dollar credits (credits) accumulated in CCA pools are used to pay research expenses. In some cases, the Adviser or its affiliates may request that a broker that is not a party to any particular transaction provide a specific proprietary or third-party product or service, which would be paid with credits from the CCA pool. The administration of brokerage and research products and services is managed separately from the trading desks, and traders have no responsibility for administering the research program, including the payment for research. The Adviser and/or its affiliates, at times, use a third-party aggregator to facilitate payments to research providers. Where an aggregator is involved, the aggregator would maintain credits in an account that is segregated from the aggregator's proprietary assets and the assets of its other clients and uses those credits to pay research providers as instructed by the Adviser or its affiliates. Furthermore, where permissible under applicable law, certain of the brokerage and research products and services that the Adviser or its affiliates receive are furnished by brokers on their own initiative, either in connection with a particular transaction or as part of their overall services. Some of these brokerage and research products or services may be provided at no additional cost to the Adviser or its affiliates or have no explicit cost associated with them. In addition, the Adviser or its affiliates may request that a broker provide a specific proprietary or third-party product or service, certain of which third-party products or services may be provided by a broker that is not a party to a particular transaction and is not connected with the transacting broker's overall services.

The Adviser's Decision-Making Process. In connection with the allocation of fund brokerage, the Adviser and/or its affiliates make a good faith determination that the compensation paid to brokers and dealers is reasonable in relation to the value of the brokerage and/or research products and services provided to the Adviser and/or its affiliates, viewed in terms of the particular transaction for the fund or the Adviser's or its affiliates' overall responsibilities to that fund or other investment companies and investment accounts for which the Adviser or its affiliates have investment discretion; however, each brokerage and research product or service received in connection with the fund's brokerage does not benefit all funds and certain funds will receive the benefit of the brokerage and research product or services obtained with other funds' commissions. As required under applicable laws or fund policy, commissions generated by certain funds may only be used to obtain certain brokerage and research products and services. As a result, certain funds will pay more proportionately for certain types of brokerage and research products and services than others, while the overall amount of brokerage and research products and services paid by each fund continues to be allocated equitably. While the Adviser and its affiliates take into account the brokerage and/or research products and services provided by a broker or dealer in determining whether compensation paid is reasonable, neither the Adviser, its affiliates, nor the fund incur an obligation to any broker, dealer, or third party to pay for any brokerage and research product or service (or portion thereof) by generating a specific amount of compensation or otherwise. Typically, for funds managed by the Adviser or its affiliates outside of the European Union or the United Kingdom, these brokerage and research products and services assist the Adviser or its affiliates in terms of their overall investment responsibilities to the fund or any other investment companies and investment accounts for which the Adviser or its affiliates may have investment discretion. Certain funds or investment accounts may use brokerage commissions to acquire brokerage and research products and services that also benefit other funds or accounts managed by the Adviser or its affiliates, and not every fund or investment account uses the brokerage and research products and services that may have been acquired through that fund's commissions.

Research Contracts. The Adviser and/or its affiliates have arrangements with certain third-party research providers and brokers through whom the Adviser and/or its affiliates effect fund trades, whereby the Adviser and/or its affiliates may pay with fund commissions or hard dollars for all or a portion of the cost of research products and services purchased from such research providers or brokers. If hard dollar payments are used, the Adviser and/or its affiliates, at times, will cause the fund to pay more for execution than the lowest commission rate available from the broker providing research products and services to the Adviser and/or its affiliates, or that may be available from another broker. The Adviser's and/or its affiliates' determination to pay for research products and services separately is wholly voluntary on the Adviser's or its affiliates' part and may be extended to additional brokers or discontinued with any broker participating in this arrangement.

Funds Managed within the European Union or the United Kingdom. The Adviser and its affiliates have established policies and procedures relating to brokerage commission uses in compliance with the revised Markets in Financial Instruments Directive in the European Union, commonly referred to as "MiFID II", as implemented in the United Kingdom through the Conduct of Business Sourcebook Rules of the UK Financial Conduct Authority (the FCA), where applicable.

Funds, or portions thereof, that are managed within the United Kingdom by FMR Investment Management (UK) Limited (FMR UK) use research payment accounts (RPAs) to cover costs associated with equity and high income external research that is consumed by those funds or investment accounts in accordance with MiFID II and FCA regulations. With RPAs, funds pay for external research through a separate research charge that is generally assessed and collected alongside the execution commission. For funds that use an RPA, FMR UK establishes a research budget. The budget is set by first grouping funds or investment accounts by strategy (e.g., asset allocation, blend, growth, etc.), and then determining what external research is consumed to support the strategies and portfolio management services provided within the European Union or the United Kingdom. In this regard, research budgets are set by research needs and are not otherwise linked to the volume or value of transactions executed on behalf of the fund or investment account. For funds where portions are managed both within and outside of the United Kingdom, external research may be paid using both a CCA and an RPA. Determinations of what is eligible research and how costs are allocated are made in accordance with the Adviser's and its affiliates' policies and procedures. Costs for research consumed by funds that use an RPA will be allocated among the funds or investment accounts within defined strategies pro rata based on the assets under management for each fund or investment account. While the research charge paid on behalf of any one fund that uses an RPA varies over time, the overall research charge determined at the fund level on an annual basis will not be exceeded.

FMR UK is responsible for managing the RPA and may delegate its administration to a third-party administrator for the facilitation of the purchase of external research and payments to research providers. RPA assets will be maintained in accounts at a third-party depository institution, held in the name of FMR UK. FMR UK provides on request, a summary of: (i) the providers paid from the RPA; (ii) the total amount they were paid over a defined period; (iii) the benefits and services received by FMR UK; and (iv) how the total amount spent from the RPA compares to the research budget set for that period, noting any rebate or carryover if residual funds remain in the RPA.

Impacted funds, like those funds that participate in CCA pools, at times, will make payments to a broker that include both an execution commission and a research charge, but unlike CCAs (for which research charges may be retained by the CCA broker and credited to the CCA, as described above), the broker will receive separate payments for the execution commission and the research charge and will promptly remit the research charge to the RPA. Assets in the RPA are used to satisfy external research costs consumed by the funds.

If the costs of paying for external research exceed the amount initially agreed in relation to funds in a given strategy, the Adviser or its affiliates may continue to charge those funds or investment accounts beyond the initially agreed amount in accordance with MiFID II, continue to acquire external research for the funds or investment accounts using its own resources, or cease to purchase external research for those funds or investment accounts until the next annual research budget. If assets for specific funds remain in the RPA at the end of a period, they may be rolled over to the next period to offset next year's research charges for those funds or rebated to those funds.

Funds managed by FMR UK that trade only fixed income securities will not participate in RPAs because fixed income securities trade based on spreads rather than commissions, and thus unbundling the execution commission and research charge is impractical. Therefore, FMR UK and its affiliates have established policies and procedures to ensure that external research that is paid for through RPAs is not made available to FMR UK portfolio managers that manage fixed income funds or investment accounts in any manner inconsistent with MiFID II and FCA regulations.

Commission Recapture

From time to time, the Adviser or its affiliates engages in brokerage transactions with brokers (who are not affiliates of the Adviser) who have entered into arrangements with the Adviser or its affiliates under which the broker will, at times, rebate a portion of the compensation paid by a fund (commission recapture). Not all brokers with whom the fund trades have been asked to participate in brokerage commission recapture.

Affiliated Transactions

The Adviser or its affiliates place trades with certain brokers, including National Financial Services LLC (NFS), through its Fidelity Capital Markets (FCM) division, and Kezar Trading LLC (formerly Luminex Trading & Analytics LLC) (Kezar Trading), with whom they are under common control or otherwise affiliated, provided the Adviser or its affiliates determine that these affiliates' trade-execution abilities and costs are comparable to those of non-affiliated, qualified brokerage firms, and that such transactions be executed in accordance with applicable rules under the 1940 Act and procedures adopted by the Board of Trustees of the fund and subject to other applicable law. In addition, from time to time, the Adviser or its affiliates place trades with brokers that use NFS or Fidelity Clearing Canada ULC (FCC) as a clearing agent and/or use Level ATS, an alternative trading system that is deemed to be affiliated with the Adviser, for execution services.

In certain circumstances, trades are executed through alternative trading systems or national securities exchanges in which the Adviser or its affiliates have an interest. Any decision to execute a trade through an alternative trading system or exchange in which the Adviser or its affiliates have an interest would be made in accordance with applicable law, including best execution obligations. For trades placed on such a system or exchange, not limited to ones in which the Adviser or its affiliates have an ownership interest, the Adviser or its affiliates derive benefit in the form of increased valuation(s) of its equity interest, where it has an ownership interest, or other remuneration, including rebates.

The Trustees of the fund have approved procedures whereby a fund is permitted to purchase securities that are offered in underwritings in which an affiliate of the adviser or certain other affiliates participate. In addition, for underwritings where such an affiliate participates as a principal underwriter, certain restrictions may apply that could, among other things, limit the amount of securities that the fund could purchase in the underwritings.

Non-U.S. Securities Transactions

To facilitate trade settlement and related activities in non-U.S. securities transactions, the Adviser or its affiliates effect spot foreign currency transactions with foreign currency dealers. In certain circumstances, due to local law and regulation, logistical or operational challenges, or the process for settling securities transactions in certain markets (e.g., short settlement periods), spot currency transactions are effected on behalf of funds by parties other than the Adviser or its affiliates, including funds' custodian banks (working through sub-custodians or agents in the relevant non-U.S. jurisdiction) or broker-dealers that executed the related securities transaction.

Trade Allocation

Although the Trustees and officers of the fund are substantially the same as those of certain other Fidelity® funds, investment decisions for the fund are made independently from those of other Fidelity® funds or investment accounts (including proprietary accounts). The same security is often held in the portfolio of more than one of these funds or investment accounts. Simultaneous transactions are inevitable when several funds and investment accounts are managed by the same investment adviser, or an affiliate thereof, particularly when the same security is suitable for the investment objective of more than one fund or investment account.

When two or more funds or investment accounts are simultaneously engaged in the purchase or sale of the same security or instrument, the prices and amounts are allocated in accordance with procedures believed by the Adviser to be appropriate and equitable to each fund or investment account. In some cases this could have a detrimental effect on the price or value of the security or instrument as far as the fund is concerned. In other cases, however, the ability of the fund to participate in volume transactions will produce better executions and prices for the fund.

Commissions Paid

A fund may pay compensation including both commissions and spreads in connection with the placement of portfolio transactions. The amount of brokerage commissions paid by a fund may change from year to year because of, among other things, changing asset levels, shareholder activity, and/or portfolio turnover.

For the fiscal year(s) ended April 30, 2024, 2023, and 2022, Fidelity® Treasury Only Money Market Fund paid no brokerage commissions.

During the fiscal year ended April 30, 2024, Fidelity® Treasury Only Money Market Fund paid no brokerage commissions to firms for providing research or brokerage services.

During the twelve-month period ended March 31, 2024, Fidelity® Treasury Only Money Market Fund did not allocate brokerage commissions to firms for providing research or brokerage services.

VALUATION

The NAV is the value of a single share. NAV is computed by adding a class's pro rata share of the value of a fund's investments, cash, and other assets, subtracting the class's pro rata share of the fund's liabilities, subtracting the liabilities allocated to the class, and dividing the result by the number of shares of that class that are outstanding.

The Board of Trustees has designated the fund's investment adviser as the valuation designee responsible for the fair valuation function and performing fair value determinations as needed. The adviser has established a Fair Value Committee (the Committee) to carry out the day-to-day fair valuation responsibilities and has adopted policies and procedures to govern the fair valuation process and the activities of the Committee.

A fund's adviser through the Committee engages in oversight activities with respect to the fund's pricing services, which includes, among other things, testing the prices provided by pricing services prior to calculation of a fund's NAV, conducting periodic due diligence meetings, and periodically reviewing the methodologies and inputs used by these services.

Shares of open-end investment companies (including any underlying money market Central funds) held by a fund are valued at their respective NAVs.

Other portfolio securities and assets held by a fund are valued on the basis of amortized cost. This technique involves initially valuing an instrument at its cost as adjusted for amortization of premium or accretion of discount rather than its current market value. The amortized cost value of an instrument may be higher or lower than the price the fund would receive if it sold the instrument.

At such intervals as they deem appropriate, the Trustees consider the extent to which NAV calculated using market valuations would deviate from the $1.00 per share calculated using amortized cost valuation. If the Trustees believe that a deviation from the fund's amortized cost per share may result in material dilution or other unfair results to shareholders, the Trustees have agreed to take such corrective action, if any, as they deem appropriate to eliminate or reduce, to the extent reasonably practicable, the dilution or unfair results. Such corrective action could include selling portfolio instruments prior to maturity to realize capital gains or losses or to shorten average portfolio maturity; withholding dividends; redeeming shares in kind; establishing NAV by using available market quotations; and such other measures as the Trustees may deem appropriate.

In determining the fair value of a private placement security for which market quotations are not available, the Committee generally applies one or more valuation methods including the market approach, income approach and cost approach. The market approach considers factors including the price of recent investments in the same or a similar security or financial metrics of comparable securities. The income approach considers factors including expected future cash flows, security specific risks and corresponding discount rates. The cost approach considers factors including the value of the security's underlying assets and liabilities.

The fund's adviser reports to the Board information regarding the fair valuation process and related material matters.

BUYING AND SELLING INFORMATION

Shares are offered only to certain Stock Plan Services accounts.

The fund may make redemption payments in whole or in part in readily marketable securities or other property pursuant to procedures approved by the Trustees if Fidelity Management & Research Company LLC determines it is in the best interests of the fund. Such securities or other property will be valued for this purpose as they are valued in computing the NAV of a fund or class, as applicable. Shareholders that receive securities or other property will realize, upon receipt, a gain or loss for tax purposes, and will incur additional costs and be exposed to market risk prior to and upon the sale of such securities or other property.

DISTRIBUTIONS AND TAXES

Dividends. Because the fund's income is primarily derived from interest, dividends from the fund generally will not qualify for the dividends-received deduction available to corporate shareholders or the long-term capital gains tax rates available to individuals. Short-term capital gains are taxable at ordinary income tax rates. Distributions by the fund to tax-advantaged retirement plan accounts are not taxable currently (but you may be taxed later, upon withdrawal of your investment from such account).

Capital Gain Distributions. The fund may distribute any net realized capital gains once a year or more often (as legally permissible), as necessary.

The following table shows the fund's aggregate capital loss carryforward as of April 30, 2024, which is available to offset future capital gains. A fund's ability to utilize its capital loss carryforwards in a given year or in total may be limited.

State and Local Tax Issues. For mutual funds organized as business trusts, state law provides for a pass-through of the state and local income tax exemption afforded to direct owners of U.S. Government securities. Some states limit this pass-through to mutual funds that invest a certain amount in U.S. Government securities, and some types of securities, such as repurchase agreements and some agency-backed securities, may not qualify for this benefit. The tax treatment of your dividends from a fund will be the same as if you directly owned a proportionate share of the U.S. Government securities. Because the income earned on certain U.S. Government securities is exempt from state and local personal income taxes, the portion of dividends from a fund attributable to these securities will also be free from state and local personal income taxes. The exemption from state and local personal income taxation does not preclude states from assessing other taxes on the ownership of U.S. Government securities.

Tax Status of the Fund. The fund intends to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code so that it will not be liable for federal tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company, and avoid being subject to federal income or excise taxes at the fund level, the fund intends to distribute substantially all of its net investment income and net realized capital gains within each calendar year as well as on a fiscal year basis (if the fiscal year is other than the calendar year), and intends to comply with other tax rules applicable to regulated investment companies.

Other Tax Information. The information above is only a summary of some of the tax consequences generally affecting the fund and its shareholders, and no attempt has been made to discuss individual tax consequences. It is up to you or your tax preparer to determine whether the sale of shares of the fund resulted in a capital gain or loss or other tax consequence to you. In addition to federal income taxes, shareholders may be subject to foreign, state and local taxes on fund distributions, and shares may be subject to state and local personal property taxes. Investors should consult their tax advisers to determine whether the fund is suitable to their particular tax situation.

Non-U.S. Shareholders. Fund distributions to non-US shareholders allocable from U.S.-source interest income or from capital gains will generally be properly reported as such and therefore eligible to be free from U.S. federal withholding tax.  Distributions (if any) to non-U.S. shareholders other than dividends the fund properly reports as capital gain dividends or dividends from U.S. source interest income (or from short-term capital gains) generally are subject to withholding on U.S. federal income tax at the rate of 30% (or an applicable lower treaty rate). Any capital gain realized by a non-U.S. shareholder upon a sale or redemption of fund shares will generally not be subject to U.S. federal income or withholding tax unless the gain is effectively connected with the shareholder's trade or business in the U.S or, in the case of a nonresident alien individual, such individual's presence in the United States exceeds certain threshold and certain other conditions are met. Non-U.S. shareholders may be subject to estate tax with respect to their fund shares. Withholding of U.S. federal income tax at a 30% rate is required with respect to payments of taxable dividends made to certain non-U.S. entities that fail to comply (or to be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. Shareholders may be requested to provide additional information to enable the applicable withholding agent to determine whether withholding is required.

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance. As of September 30, 2024, except for Lester Owens, each of the Trustees oversees 318 funds. As of October 1, 2024, the date of his appointment as Trustee, Mr. Owens oversees 318 funds.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee. Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees. Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years.

Experience, Skills, Attributes, and Qualifications of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Michael E. Kenneally serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's alternative investment, high income and other equity funds. The asset allocation funds may invest in Fidelity® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity® funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks. The Board, acting through its committees, has charged FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above. Because the day-to-day operations and activities of the fund are carried out by or through FMR, its affiliates, and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees. While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees. In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board. The Operations Committee also worked and continues to work with FMR to enhance the stress tests required under SEC regulations for money market funds. Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity® funds. The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Standing Committees of the Trustees. The Board of Trustees has established various committees to support the Independent Trustees in acting independently in pursuing the best interests of the funds and their shareholders. Currently, the Board of Trustees has four standing committees. The members of each committee are Independent Trustees.

The Operations Committee is composed of all of the Independent Trustees, with Mr. Gartland currently serving as Chair. The committee normally meets at least six times a year, or more frequently as called by the Chair, and serves as a forum for consideration of issues of importance to, or calling for particular determinations by, the Independent Trustees. The committee considers matters involving potential conflicts of interest between the funds and FMR and its affiliates, including matters involving potential claims of one or more funds (e.g., for reimbursements of expenses or losses) against FMR, and reviews proposed contracts and the proposed continuation of contracts between the funds and FMR and its affiliates, and annually reviews and makes recommendations regarding contracts with third parties unaffiliated with FMR, including insurance coverage and custody agreements. The committee has oversight of compliance issues not specifically within the scope of any other committee. These matters include, but are not limited to, significant non-conformance with contract requirements and other significant regulatory matters and recommending to the Board of Trustees the designation of a person to serve as the funds' CCO. The committee (i) serves as a primary point of contact (generally after the Independent Trustee who serves as a liaison for the CCO) for the CCO with regard to Board-related functions; (ii) oversees the annual performance review of the CCO; (iii) makes recommendations concerning the CCO's compensation; and (iv) makes recommendations as needed in respect of the removal of the CCO.

The Audit Committee is composed of all of the Independent Trustees, with Ms. Bishop currently serving as Chair. At least one committee member will be an "audit committee financial expert" as defined by the SEC. The committee normally meets four times a year, or more frequently as called by the Chair or a majority of committee members. The committee meets separately, at least annually, with the funds' Treasurer, with the funds' Chief Financial Officer, with personnel responsible for the internal audit function of FMR LLC, with the funds' outside auditors, and with the funds' CCO. The committee has direct responsibility for the appointment, compensation, and oversight of the work of the outside auditors employed by the funds. The committee assists the Trustees in overseeing and monitoring: (i) the systems of internal accounting and financial controls of the funds and the funds' service providers (to the extent such controls impact the funds' financial statements); (ii) the funds' auditors and the annual audits of the funds' financial statements; (iii) the financial reporting processes of the funds; (iv) whistleblower reports; and (v) the accounting policies and disclosures of the funds. The committee considers and acts upon (i) the provision by any outside auditor of any non-audit services for any fund, and (ii) the provision by any outside auditor of certain non-audit services to fund service providers and their affiliates to the extent that such approval (in the case of this clause (ii)) is required under applicable regulations of the SEC. It is responsible for approving all audit engagement fees and terms for the funds and for resolving disagreements between a fund and any outside auditor regarding any fund's financial reporting. Auditors of the funds report directly to the committee. The committee will obtain assurance of independence and objectivity from the outside auditors, including a formal written statement delineating all relationships between the auditor and the funds and any service providers consistent with the rules of the Public Company Accounting Oversight Board. It oversees and receives reports on the funds' service providers' internal controls and reviews the adequacy and effectiveness of the service providers' accounting and financial controls, including: (i) any significant deficiencies or material weaknesses in the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect the funds' ability to record, process, summarize, and report financial data; (ii) any change in the fund's internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the fund's internal control over financial reporting; and (iii) any fraud, whether material or not, that involves management or other employees who have a significant role in the funds' or service providers internal controls over financial reporting. The committee will also review any correspondence with regulators or governmental agencies or published reports that raise material issues regarding the funds' financial statements or accounting policies. These matters may also be reviewed by the Operations Committee. The committee reviews at least annually a report from each outside auditor describing any material issues raised by the most recent internal quality control, peer review, or Public Company Accounting Oversight Board examination of the auditing firm and any material issues raised by any inquiry or investigation by governmental or professional authorities of the auditing firm and in each case any steps taken to deal with such issues. The committee will oversee and receive reports on the funds' financial reporting process from the funds' Treasurer and outside auditors and will oversee the resolution of any disagreements concerning financial reporting among applicable parties. The committee will discuss with FMR, the funds' Treasurer, outside auditors and, if appropriate, internal audit personnel of FMR LLC their qualitative judgments about the appropriateness and acceptability of accounting principles and financial disclosure practices used or proposed for adoption by the funds. The committee will review with FMR, the funds' outside auditor, internal audit personnel of FMR LLC and legal counsel, as appropriate, matters related to the audits of the funds' financial statements. The committee will discuss regularly and oversee the review of the internal controls of the funds and their service providers with respect to accounting, financial matters and risk management programs related to the funds. The committee will review periodically the funds' major internal controls exposures and the steps that have been taken to monitor and control such exposures.

The Fair Valuation Committee is composed of all of the Independent Trustees, with Mr. Murray currently serving as Chair. The Committee normally meets quarterly, or more frequently as called by the Chair. The Fair Valuation Committee oversees the valuation of securities held by the funds, including the fair valuation of securities by the funds' valuation designee. The Committee receives and reviews related reports and information consistent with its oversight obligations.

The Governance and Nominating Committee is composed of Messrs. Gartland (Chair) and Murray, and Ms. Acton (Vice Chair). The committee meets as called by the Chair. With respect to fund governance and board administration matters, the committee periodically reviews procedures of the Board of Trustees and its committees (including committee charters) and periodically reviews compensation of Independent Trustees. The committee monitors corporate governance matters and makes recommendations to the Board of Trustees on the frequency and structure of the Board of Trustee meetings and on any other aspect of Board procedures. It acts as the administrative committee under the retirement plan for Independent Trustees who retired prior to December 30, 1996 and under the fee deferral plan for Independent Trustees. It monitors the performance of legal counsel employed by both the funds and the Independent Trustees. The committee will engage and oversee any counsel utilized by the Independent Trustees as may be necessary or appropriate under applicable regulations or otherwise. The committee also approves Board administrative matters applicable to Independent Trustees, such as expense reimbursement policies and compensation for attendance at meetings, conferences and other events. The committee oversees compliance with the provisions of the code of ethics and any supplemental policies regarding personal securities transactions applicable to the Independent Trustees. The committee reviews the functioning of each Board committee and makes recommendations for any changes, including the creation or elimination of standing or ad hoc Board committees. The committee monitors regulatory and other developments to determine whether to recommend modifications to the committee's responsibilities or other Trustee policies and procedures in light of rule changes, reports concerning "recommended practices" in corporate governance and other developments in mutual fund governance. The committee meets with Independent Trustees at least once a year to discuss matters relating to fund governance. The committee recommends that the Board establish such special or ad hoc Board committees as may be desirable or necessary from time to time in order to address ethical, legal, or other matters that may arise. The committee also oversees the annual self-evaluation of the Board of Trustees and establishes procedures to allow it to exercise this oversight function. In conducting this oversight, the committee shall address all matters that it considers relevant to the performance of the Board of Trustees and shall report the results of its evaluation to the Board of Trustees, including any recommended amendments to the principles of governance, and any recommended changes to the funds' or the Board of Trustees' policies, procedures, and structures. The committee reviews periodically the size and composition of the Board of Trustees as a whole and recommends, if necessary, measures to be taken so that the Board of Trustees reflects the appropriate balance of knowledge, experience, skills, expertise, and diversity required for the Board as a whole and contains at least the minimum number of Independent Trustees required by law. The committee makes nominations for the election or appointment of Independent Trustees and non-management Members of any Advisory Board, and for membership on committees. The committee has the authority to retain and terminate any third-party advisers, including authority to approve fees and other retention terms. Such advisers may include search firms to identify Independent Trustee candidates and board compensation consultants. The committee may conduct or authorize investigations into or studies of matters within the committee's scope of responsibilities, and may retain, at the funds' expense, such independent counsel or other advisers as it deems necessary. The committee will consider nominees to the Board of Trustees recommended by shareholders based upon the criteria applied to candidates presented to the committee by a search firm or other source. Recommendations, along with appropriate background material concerning the candidate that demonstrates his or her ability to serve as an Independent Trustee of the funds, should be submitted to the Chair of the committee at the address maintained for communications with Independent Trustees. If the committee retains a search firm, the Chair will generally forward all such submissions to the search firm for evaluation. With respect to the criteria for selecting Independent Trustees, it is expected that all candidates will possess the following minimum qualifications: (i) unquestioned personal integrity; (ii) not an interested person of the funds within the meaning of the 1940 Act; (iii) does not have a material relationship (e.g., commercial, banking, consulting, legal, or accounting) with the adviser, any sub-adviser or their affiliates that could create an appearance of lack of independence in respect of the funds; (iv) has the disposition to act independently in respect of FMR and its affiliates and others in order to protect the interests of the funds and all shareholders; (v) ability to attend regularly scheduled Board meetings during the year; (vi) demonstrates sound business judgment gained through broad experience in significant positions where the candidate has dealt with management, technical, financial, or regulatory issues; (vii) sufficient financial or accounting knowledge to add value in the complex financial environment of the funds; (viii) experience on corporate or other institutional oversight bodies having similar responsibilities, but which board memberships or other relationships could not result in business or regulatory conflicts with the funds; and (ix) capacity for the hard work and attention to detail that is required to be an effective Independent Trustee in light of the funds' complex regulatory, operational, and marketing setting. The Governance and Nominating Committee may determine that a candidate who does not have the type of previous experience or knowledge referred to above should nevertheless be considered as a nominee if the Governance and Nominating Committee finds that the candidate has additional qualifications such that his or her qualifications, taken as a whole, demonstrate the same level of fitness to serve as an Independent Trustee.

CONTROL OF INVESTMENT ADVISERS

FMR LLC, as successor by merger to FMR Corp., is the ultimate parent company of FMR, FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited. The voting common shares of FMR LLC are divided into two series. Series B is held predominantly by members of the Johnson family, including Abigail P. Johnson, directly or through trusts, and is entitled to 49% of the vote on any matter acted upon by the voting common shares. Series A is held predominantly by non-Johnson family member employees of FMR LLC and its affiliates and is entitled to 51% of the vote on any such matter. The Johnson family group and all other Series B shareholders have entered into a shareholders' voting agreement under which all Series B shares will be voted in accordance with the majority vote of Series B shares. Under the 1940 Act, control of a company is presumed where one individual or group of individuals owns more than 25% of the voting securities of that company. Therefore, through their ownership of voting common shares and the execution of the shareholders' voting agreement, members of the Johnson family may be deemed, under the 1940 Act, to form a controlling group with respect to FMR LLC.

At present, the primary business activities of FMR LLC and its subsidiaries are: (i) the provision of investment advisory, management, shareholder, investment information and assistance and certain fiduciary services for individual and institutional investors; (ii) the provision of securities brokerage services; (iii) the management and development of real estate; and (iv) the investment in and operation of a number of emerging businesses.

FMR, FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, Fidelity Management & Research (Japan) Limited, Fidelity Distributors Company LLC (FDC), and the fund have adopted a code of ethics under Rule 17j-1 of the 1940 Act that sets forth employees' fiduciary responsibilities regarding the fund, establishes procedures for personal investing, and restricts certain transactions. Employees subject to the code of ethics, including Fidelity investment personnel, may invest in securities for their own investment accounts, including securities that may be purchased or held by the fund.

MANAGEMENT CONTRACT

The fund has entered into a management contract with FMR, pursuant to which FMR furnishes investment advisory and other services.

Management Services. Under the terms of its management contract with the fund, FMR acts as investment adviser and, subject to the supervision of the Board of Trustees, has overall responsibility for directing the investments of the fund in accordance with its investment objective, policies and limitations. FMR also provides the fund with all necessary office facilities and personnel for servicing the fund's investments, compensates all officers of the fund and all Trustees who are interested persons of the trust or of FMR, and compensates all personnel of the fund or FMR performing services relating to research, statistical and investment activities.

In addition, FMR or its affiliates, subject to the supervision of the Board of Trustees, provide the management and administrative services necessary for the operation of the fund. These services include providing facilities for maintaining the fund's organization; supervising relations with custodians, transfer and pricing agents, accountants, underwriters and other persons dealing with the fund; preparing all general shareholder communications and conducting shareholder relations; maintaining the fund's records and the registration of the fund's shares under federal securities laws and making necessary filings under state securities laws; developing management and shareholder services for the fund; and furnishing reports, evaluations and analyses on a variety of subjects to the Trustees.

Management-Related Expenses. Under the terms of the fund's management contract, FMR, either itself or through an affiliate, is responsible for payment of all operating expenses of the fund or each class thereof, as applicable, with limited exceptions. Specific expenses payable by FMR include expenses for typesetting, printing, and mailing proxy materials to shareholders, legal expenses, fees of the custodian, auditor, and interested Trustees, a fund's proportionate share of insurance premiums and Investment Company Institute dues, and the costs of registering shares under federal securities laws and making necessary filings under state securities laws. FMR also pays all fees associated with transfer agency services and pricing and bookkeeping services agreements.

FMR pays all other expenses of the fund with the following exceptions: fees and expenses of the Independent Trustees, interest, taxes, money market insurance premiums (beginning January 1, 2004), if any, and such non-recurring expenses as may arise, including costs of any litigation to which the fund may be a party, and any obligation it may have to indemnify its officers and Trustees with respect to litigation. The fund shall pay its non-operating expenses, including brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable.

Management Fee.

Class OUS pays FMR a monthly all-inclusive management fee at an annual rate of 0.37% of its average daily net assets throughout the month. A different all-inclusive management fee rate is applicable to each class of the fund. The difference between classes is the result of separate arrangements for class level services and/or waivers of certain expenses (if any). It is not the result of any difference in advisory or custodial fees or other expenses related to the management of the fund's assets, which do not vary by class. Different fees and expenses will affect performance.

The management fee paid to FMR by the fund is reduced by an amount equal to the fees and expenses paid by the fund to the Independent Trustees.

The following table shows the amount of management fees paid by the fund for the fiscal year(s) ended April 30, 2024, 2023, and 2022 to its current manager and prior affiliated manager(s), if any, and the amount of credits reducing management fees.

Fund(s)	Fiscal Years Ended		Amount of Credits Reducing Management Fees		Management Fees Paid to Investment Adviser
Fidelity® Treasury Only Money Market Fund	2024	$	0	$	18,579,246
	2023	$	0	$	13,631,831
	2022	$	510	$	15,146,081

FMR may, from time to time, voluntarily reimburse all or a portion of a fund's or, in the case of a multiple class fund, a class's operating expenses. FMR retains the ability to be repaid for these expense reimbursements in the amount that expenses fall below the limit prior to the end of the fiscal year.

Expense reimbursements will increase returns and yield, and repayment of the reimbursement will decrease returns and yield.

Sub-Advisers - FMR Investment Management (UK) Limited, Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Limited. 

On behalf of the fund, FMR has entered into sub-advisory agreements with Fidelity Management & Research (Hong Kong) Limited (FMR H.K.) and Fidelity Management & Research (Japan) Limited (FMR Japan).

On behalf of the fund, FMR has entered into a sub-advisory agreement with FMR UK.

Pursuant to the sub-advisory agreements, FMR may receive from the sub-advisers investment research and advice on issuers outside the United States (non-discretionary services) and FMR may grant the sub-advisers investment management authority and the authority to buy and sell securities if FMR believes it would be beneficial to the fund (discretionary services). 

FMR, and not the fund, pays the sub-advisers. 

PROXY VOTING GUIDELINES

Fidelity Proxy Voting Guidelines

I. Introduction

These guidelines are intended to help Fidelity's customers and the companies in which Fidelity invests understand how Fidelity votes proxies to further the values that have sustained Fidelity for over 75 years. Our core principles sit at the heart of our voting philosophy; putting our customers' and fund shareholders' long-term interests first and investing in companies that share our approach to creating value over the long-term guides everything we do. Fidelity generally adheres to these guidelines in voting proxies and our Stewardship Principles serve as the foundation for these guidelines. Our evaluation of proxies reflects information from many sources, including management or shareholders of a company presenting a proposal and proxy voting advisory firms. Fidelity maintains the flexibility to vote individual proxies based on our assessment of each situation.

In evaluating proxies, Fidelity considers factors that are financially material to individual companies and investing funds' investment objectives and strategies in support of maximizing long-term shareholder value. This includes considering the company's approach to financial and operational, human, and natural capital and the impact of that approach on the potential future value of the business.

Fidelity will vote on proposals not specifically addressed by these guidelines based on an evaluation of a proposal's likelihood to enhance the long-term economic returns or profitability of the company or to maximize long-term shareholder value. Fidelity will not be influenced by business relationships or outside perspectives that may conflict with the interests of the funds and their shareholders.

II. Board of Directors and Corporate Governance

Directors of public companies play a critical role in ensuring that a company and its management team serve the interests of its shareholders. Fidelity believes that through proxy voting, it can help ensure accountability of management teams and boards of directors, align management and shareholder interests, and monitor and assess the degree of transparency and disclosure with respect to executive compensation and board actions affecting shareholders' rights. The following general guidelines are intended to reflect these proxy voting principles.

A. Election of Directors

Fidelity will generally support director nominees in elections where all directors are unopposed (uncontested elections), except where board composition raises concerns, and/or where a director clearly appears to have failed to exercise reasonable judgment or otherwise failed to sufficiently protect the interests of shareholders.

Fidelity will evaluate board composition and generally will oppose the election of certain or all directors if, by way of example:

1. The board is not composed of a majority of independent directors.

2. The board's audit, compensation, and nominating/governance committees or their equivalents are not sufficiently independent.

3. There is no gender diversity on the board, or if a board of ten or more members has fewer than two gender diverse directors.

4. There are no racially or ethnically diverse directors on the board.

5. The director is a public company CEO who sits on more than two unaffiliated public company boards.

6. The director, other than a CEO, sits on more than five unaffiliated public company boards.

7. The director attended fewer than 75% of the total number of meetings of the board and its committees on which the director served during the company's prior fiscal year, absent extenuating circumstances.

While Fidelity generally considers the requirements of the relevant listing standards in determining director, board, and committee independence, we may apply more stringent independence criteria and adapt such criteria for certain foreign markets, taking into consideration listing requirements as well as differing laws, regulation, and/or practices in the relevant market. For example, Fidelity generally will find non-independent

1. Former CEOs.

2. Company founders.

3. Directors or director family members that were employed as senior executives by the company within the past five years.

Fidelity also may evaluate financial relationships, equity ownership, and voting rights in assessing the independence of director nominees.

In addition, Fidelity will evaluate board actions and generally will oppose the election of certain or all directors if, by way of example:

1. The company made a commitment to modify a proposal or practice to conform to these guidelines, and failed to act on that commitment.

2. For reasons described below under the sections entitled Compensation and Anti-Takeover Provisions and Director Elections.

B. Contested Director Elections

On occasion, directors are forced to compete for election against outside director nominees (contested elections). Fidelity believes that strong management creates long-term shareholder value. As a result, Fidelity generally will vote in support of management of companies in which the funds' assets are invested. Fidelity will vote its proxy on a case-by-case basis in a contested election, taking into consideration a number of factors, amongst others:

1. Management's track record and strategic plan for enhancing shareholder value;

2. The long-term performance of the company compared to its industry peers; and

3. The qualifications of the shareholder's and management's nominees.

Fidelity will vote for the outcome it believes has the best prospects for maximizing shareholder value over the long-term.

C. Cumulative Voting Rights

Under cumulative voting, each shareholder may exercise the number of votes equal to the number of shares owned multiplied by the number of directors up for election. Shareholders may cast all of their votes for a single nominee (or multiple nominees in varying amounts). With regular (non-cumulative) voting, by contrast, shareholders cannot allocate more than one vote per share to any one director nominee. Fidelity believes that cumulative voting can be detrimental to the overall strength of a board. Generally, therefore, Fidelity will oppose the introduction of, and support the elimination of, cumulative voting rights.

D. Classified Boards

A classified board is one that elects only a percentage of its members each year (usually one-third of directors are elected to serve a three-year term). This means that at each annual meeting only a subset of directors is up for re-election. Fidelity believes that, in general, classified boards are not as accountable to shareholders as declassified boards. For this and other reasons, Fidelity generally will oppose a board's adoption of a classified board structure and support declassification of existing boards.

E. Independent Chairperson

In general, Fidelity believes that boards should have a process and criteria for selecting the board chair, and will oppose shareholder proposals calling for, or recommending the appointment of, a non-executive or independent chairperson. If, however, based on particular facts and circumstances, Fidelity believes that appointment of a non-executive or independent chairperson appears likely to further the interests of shareholders and promote effective oversight of management by the board of directors, Fidelity will consider voting to support a proposal for an independent chairperson under such circumstances.

F. Majority Voting in Director Elections

In general, Fidelity supports proposals calling for directors to be elected by a majority of votes cast if the proposal permits election by a plurality in the case of contested elections (where, for example, there are more nominees than board seats). Fidelity may oppose a majority voting shareholder proposal where a company's board has adopted a policy requiring the resignation of an incumbent director who fails to receive the support of a majority of the votes cast in an uncontested election.

G. Proxy Access

Proxy access proposals generally require a company to amend its by-laws to allow a qualifying shareholder or group of shareholders to nominate directors on a company's proxy ballot. Fidelity believes that certain safeguards as to ownership threshold and duration of ownership are important to assure that proxy access is not misused by those without a significant economic interest in the company or those driven by short term goals. Fidelity will evaluate proxy access proposals on a case-by-case basis, but generally will support proposals that include ownership of at least 3% (5% in the case of small-cap companies) of the company's shares outstanding for at least three years; limit the number of directors that eligible shareholders may nominate to 20% of the board; and limit to 20 the number of shareholders that may form a nominating group.

H. Indemnification of Directors and Officers

In many instances there are sound reasons to indemnify officers and directors, so that they may perform their duties without the distraction of unwarranted litigation or other legal process. Fidelity generally supports charter and by-law amendments expanding the indemnification of officers or directors, or limiting their liability for breaches of care unless Fidelity is dissatisfied with their performance or the proposal is accompanied by anti-takeover provisions (see Anti-Takeover Provisions and Shareholders Rights Plans below).

III. Compensation

Incentive compensation plans can be complicated and many factors are considered when evaluating such plans. Fidelity evaluates such plans based on protecting shareholder interests and our historical knowledge of the company and its management.

A. Equity Compensation Plans

Fidelity encourages the use of reasonably designed equity compensation plans that align the interest of management with those of shareholders by providing officers and employees with incentives to increase long-term shareholder value. Fidelity considers whether such plans are too dilutive to existing shareholders because dilution reduces the voting power or economic interest of existing shareholders as a result of an increase in shares available for distribution to employees in lieu of cash compensation. Fidelity will generally oppose equity compensation plans or amendments to authorize additional shares under such plans if:

1. The company grants stock options and equity awards in a given year at a rate higher than a benchmark rate ("burn rate") considered appropriate by Fidelity and there were no circumstances specific to the company or the compensation plans that leads Fidelity to conclude that the rate of awards is otherwise acceptable.

2. The plan includes an evergreen provision, which is a feature that provides for an automatic increase in the shares available for grant under an equity compensation plan on a regular basis.

3. The plan provides for the acceleration of vesting of equity compensation even though an actual change in control may not occur.

As to stock option plans, considerations include the following:

1. Pricing: We believe that options should be priced at 100% of fair market value on the date they are granted. We generally oppose options priced at a discount to the market, although the price may be as low as 85% of fair market value if the discount is expressly granted in lieu of salary or cash bonus.

2. Re-pricing: An "out-of-the-money" (or underwater) option has an exercise price that is higher than the current price of the stock. We generally oppose the re-pricing of underwater options because it is not consistent with a policy of offering options as a form of long-term compensation. Fidelity also generally opposes a stock option plan if the board or compensation committee has re-priced options outstanding in the past two years without shareholder approval.

Fidelity generally will support a management proposal to exchange, re-price or tender for cash, outstanding options if the proposed exchange, re-pricing, or tender offer is consistent with the interests of shareholders, taking into account a variety of factors such as:

1. Whether the proposal excludes senior management and directors;

2. Whether the exchange or re-pricing proposal is value neutral to shareholders based upon an acceptable pricing model;

3. The company's relative performance compared to other companies within the relevant industry or industries;

4. Economic and other conditions affecting the relevant industry or industries in which the company competes; and

5. Any other facts or circumstances relevant to determining whether an exchange or re-pricing proposal is consistent with the interests of shareholders.

B. Employee Stock Purchase Plans

These plans are designed to allow employees to purchase company stock at a discounted price and receive favorable tax treatment when the stock is sold. Fidelity generally will support employee stock purchase plans if the minimum stock purchase price is equal to or greater than 85% (or at least 75% in the case of non-U.S. companies where a lower minimum stock purchase price is equal to the prevailing "best practices" in that market) of the stock's fair market value and the plan constitutes a reasonable effort to encourage broad based participation in the company's stock.

IV. Advisory Vote on Executive Compensation (Say on Pay) and Frequency of Say on Pay Vote

Current law requires companies to allow shareholders to cast non-binding votes on the compensation for named executive officers, as well as the frequency of such votes. Fidelity generally will support proposals to ratify executive compensation unless the compensation appears misaligned with shareholder interests or is otherwise problematic, taking into account:

- The actions taken by the board or compensation committee in the previous year, including whether the company re-priced or exchanged outstanding stock options without shareholder approval; adopted or extended a golden parachute without shareholder approval; or adequately addressed concerns communicated by Fidelity in the process of discussing executive compensation;

- The alignment of executive compensation and company performance relative to peers; and

- The structure of the compensation program, including factors such as whether incentive plan metrics are appropriate, rigorous and transparent; whether the long-term element of the compensation program is evaluated over at least a three-year period; the sensitivity of pay to below median performance; the amount and nature of non-performance-based compensation; the justification and rationale behind paying discretionary bonuses; the use of stock ownership guidelines and amount of executive stock ownership; and how well elements of compensation are disclosed.

When presented with a frequency of Say on Pay vote, Fidelity generally will support holding an annual advisory vote on Say on Pay.

A. Compensation Committee

Directors serving on the compensation committee of the Board have a special responsibility to ensure that management is appropriately compensated and that compensation, among other things, fairly reflects the performance of the company. Fidelity believes that compensation should align with company performance as measured by key business metrics. Compensation policies should align the interests of executives with those of shareholders. Further, the compensation program should be disclosed in a transparent and timely manner.

Fidelity will oppose the election of directors on the compensation committee if:

1.The compensation appears misaligned with shareholder interests or is otherwise problematic and results in concerns with:

a)The alignment of executive compensation and company performance relative to peers; and

b)The structure of the compensation program, including factors outlined above under the section entitled Advisory Vote on Executive Compensation (Say on Pay) and Frequency of Say on Pay Vote.

2. The company has not adequately addressed concerns communicated by Fidelity in the process of discussing executive compensation.

3. Within the last year, and without shareholder approval, a company's board of directors or compensation committee has either:

a) Re-priced outstanding options, exchanged outstanding options for equity, or tendered cash for outstanding options; or

b) Adopted or extended a golden parachute.

B. Executive Severance Agreements

Executive severance compensation and benefit arrangements resulting from a termination following a change in control are known as "golden parachutes." Fidelity generally will oppose proposals to ratify golden parachutes where the arrangement includes an excise tax gross-up provision; single trigger for cash incentives; or may result in a lump sum payment of cash and acceleration of equity that may total more than three times annual compensation (salary and bonus) in the event of a termination following a change in control.

V. Natural and Human Capital Issues

As part of our efforts to maximize long-term shareholder value, we incorporate consideration of human and natural capital issues into our evaluation of a company if our research has demonstrated an issue is financially material to that company and the investing funds' investment objectives and strategies.

Fidelity generally considers management's recommendation and current practice when voting on shareholder proposals concerning human and natural capital issues because it generally believes that management and the board are in the best position to determine how to address these matters. Fidelity, however, also believes that transparency is critical to sound corporate governance. Fidelity evaluates shareholder proposals concerning natural and human capital topics. To engage and vote more effectively on the growing number of submitted proposals on these topics, we developed a four-point decision-making framework. In general, Fidelity will more likely support proposals that:

•Address a topic that our research has identified as financially material;

•Provide disclosure of new or additional information to investors without being overly prescriptive;

•Provide valuable information to the business or investors by improving the landscape of investment-decision relevant information or contributing to our understanding of a company's processes and governance of the topic in question; and

•Are realistic or practical for the company to comply with.

VI. Anti-Takeover Provisions and Shareholders Rights Plans

Fidelity generally will oppose a proposal to adopt an anti-takeover provision.

Anti-takeover provisions include:

- classified boards;

- "blank check" preferred stock (whose terms and conditions may be expressly determined by the company's board, for example, with differential voting rights);

- golden parachutes;

- supermajority provisions (that require a large majority (generally between 67-90%) of shareholders to approve corporate changes as compared to a majority provision that simply requires more than 50% of shareholders to approve those changes);

- poison pills;

- provisions restricting the right to call special meetings;

- provisions restricting the right of shareholders to set board size; and

- any other provision that eliminates or limits shareholder rights.

A. Shareholders Rights Plans ("poison pills")

Poison pills allow shareholders opposed to a takeover offer to purchase stock at discounted prices under certain circumstances and effectively give boards veto power over any takeover offer. While there are advantages and disadvantages to poison pills, they can be detrimental to the creation of shareholder value and can help entrench management by deterring acquisition offers not favored by the board, but that may, in fact, be beneficial to shareholders.

Fidelity generally will support a proposal to adopt or extend a poison pill if the proposal:

1. Includes a condition in the charter or plan that specifies an expiration date (sunset provision) of no greater than five years;

2. Is integral to a business strategy that is expected to result in greater value for the shareholders;

3. Requires shareholder approval to be reinstated upon expiration or if amended;

4. Contains a mechanism to allow shareholders to consider a bona fide takeover offer for all outstanding shares without triggering the poison pill; and

5. Allows the Fidelity funds to hold an aggregate position of up to 20% of a company's total voting securities, where permissible.

Fidelity generally also will support a proposal that is crafted only for the purpose of protecting a specific tax benefit if it also believes the proposal is likely to enhance long-term economic returns or maximize long-term shareholder value.

B. Shareholder Ability to Call a Special Meeting

Fidelity generally will support shareholder proposals regarding shareholders' right to call special meetings if the threshold required to call the special meeting is no less than 25% of the outstanding stock.

C. Shareholder Ability to Act by Written Consent

Fidelity generally will support proposals regarding shareholders' right to act by written consent if the proposals include appropriate mechanisms for implementation. This means that proposals must include record date requests from at least 25% of the outstanding stockholders and consents must be solicited from all shareholders.

D. Supermajority Shareholder Vote Requirement

Fidelity generally will support proposals regarding supermajority provisions if Fidelity believes that the provisions protect minority shareholder interests in companies where there is a substantial or dominant shareholder.

VII. Anti-Takeover Provisions and Director Elections

Fidelity will oppose the election of all directors or directors on responsible committees if the board adopted or extended an anti-takeover provision without shareholder approval.

Fidelity will consider supporting the election of directors with respect to poison pills if:

- All of the poison pill's features outlined under the Anti-Takeover Provisions and Shareholders Rights section above are met when a poison pill is adopted or extended.

- A board is willing to consider seeking shareholder ratification of, or adding the features outlined under the Anti-Takeover Provisions and Shareholders Rights Plans section above to, an existing poison pill. If, however, the company does not take appropriate action prior to the next annual shareholder meeting, Fidelity will oppose the election of all directors at that meeting.

- It determines that the poison pill was narrowly tailored to protect a specific tax benefit, and subject to an evaluation of its likelihood to enhance long-term economic returns or maximize long-term shareholder value.

VIII. Capital Structure and Incorporation

These guidelines are designed to protect shareholders' value in the companies in which the Fidelity funds invest. To the extent a company's management is committed and incentivized to maximize shareholder value, Fidelity generally votes in favor of management proposals; Fidelity may vote contrary to management where a proposal is overly dilutive to shareholders and/or compromises shareholder value or other interests. The guidelines that follow are meant to protect shareholders in these respects.

A. Increases in Common Stock

Fidelity may support reasonable increases in authorized shares for a specific purpose (a stock split or re-capitalization, for example). Fidelity generally will oppose a provision to increase a company's authorized common stock if such increase will result in a total number of authorized shares greater than three times the current number of outstanding and scheduled to be issued shares, including stock options.

In the case of real estate investment trusts (REITs), however, Fidelity will oppose a provision to increase the REIT's authorized common stock if the increase will result in a total number of authorized shares greater than five times the current number of outstanding and scheduled to be issued shares.

B. Multi-Class Share Structures

Fidelity generally will support proposals to recapitalize multi-class share structures into structures that provide equal voting rights for all shareholders, and generally will oppose proposals to introduce or increase classes of stock with differential voting rights. However, Fidelity will evaluate all such proposals in the context of their likelihood to enhance long-term economic returns or maximize long-term shareholder value.

C. Incorporation or Reincorporation in another State or Country

Fidelity generally will support management proposals calling for, or recommending that, a company reincorporate in another state or country if, on balance, the economic and corporate governance factors in the proposed jurisdiction appear reasonably likely to be better aligned with shareholder interests, taking into account the corporate laws of the current and proposed jurisdictions and any changes to the company's current and proposed governing documents. Fidelity will consider supporting these shareholder proposals in limited cases if, based upon particular facts and circumstances, remaining incorporated in the current jurisdiction appears misaligned with shareholder interests.

IX. Shares of Fidelity Funds or other non-Fidelity Funds

When a Fidelity fund invests in an underlying Fidelity fund with public shareholders or a non-Fidelity investment company or business development company, Fidelity will generally vote in the same proportion as all other voting shareholders of the underlying fund (this is known as "echo voting"). Fidelity may not vote if "echo voting" is not operationally practical or not permitted under applicable laws and regulations. For Fidelity fund investments in a Fidelity Series Fund, Fidelity generally will vote in a manner consistent with the recommendation of the Fidelity Series Fund's Board of Trustees on all proposals, except where not permitted under applicable laws and regulations.

X. Foreign Markets

Many Fidelity funds invest in voting securities issued by companies that are domiciled outside the United States and are not listed on a U.S. securities exchange. Corporate governance standards, legal or regulatory requirements and disclosure practices in foreign countries can differ from those in the United States. When voting proxies relating to non-U.S. securities, Fidelity generally will evaluate proposals under these guidelines and where applicable and feasible, take into consideration differing laws, regulations and practices in the relevant foreign market in determining how to vote shares.

In certain non-U.S. jurisdictions, shareholders voting shares of a company may be restricted from trading the shares for a period of time around the shareholder meeting date. Because these trading restrictions can hinder portfolio management and could result in a loss of liquidity for a fund, Fidelity generally will not vote proxies in circumstances where such restrictions apply. In addition, certain non-U.S. jurisdictions require voting shareholders to disclose current share ownership on a fund-by-fund basis. When such disclosure requirements apply, Fidelity generally will not vote proxies in order to safeguard fund holdings information.

XI. Securities on Loan

Securities on loan as of a record date cannot be voted. In certain circumstances, Fidelity may recall a security on loan before record date (for example, in a particular contested director election or a noteworthy merger or acquisition). Generally, however, securities out on loan remain on loan and are not voted because, for example, the income a fund derives from the loan outweighs the benefit the fund receives from voting the security. In addition, Fidelity may not be able to recall and vote loaned securities if Fidelity is unaware of relevant information before record date, or is otherwise unable to timely recall securities on loan.

XII. Compliance with Legal Obligations and Avoiding Conflicts of Interest

Voting of shares is conducted in a manner consistent with Fidelity's fiduciary obligations to the funds and all applicable laws and regulations. In other words, Fidelity votes in a manner consistent with these guidelines and in the best interests of the funds and their shareholders, and without regard to any other Fidelity companies' business relationships.

Fidelity takes its responsibility to vote shares in the best interests of the funds seriously and has implemented policies and procedures to address actual and potential conflicts of interest.

XIII. Conclusion

Since its founding more than 75 years ago, Fidelity has been driven by two fundamental values: 1) putting the long-term interests of our customers and fund shareholders first; and 2) investing in companies that share our approach to creating value over the long-term. With these fundamental principles as guideposts, the funds are managed to provide the greatest possible return to shareholders consistent with governing laws and the investment guidelines and objectives of each fund.

Fidelity believes that there is a strong correlation between sound corporate governance and enhancing shareholder value. Fidelity, through the implementation of these guidelines, puts this belief into action through consistent engagement with portfolio companies on matters contained in these guidelines, and, ultimately, through the exercise of voting rights by the funds.

DISTRIBUTION SERVICES

For purposes of the following "Distribution Services" discussion, the term "shares" (as it relates to the fund) means the one class of shares of the fund offered through the prospectus to which this SAI relates.

The fund has entered into a distribution agreement with Fidelity Distributors Company LLC (FDC), an affiliate of FMR. The principal business address of FDC is 900 Salem Street, Smithfield, Rhode Island 02917. FDC is a broker-dealer registered under the Securities Exchange Act of 1934 and a member of the Financial Industry Regulatory Authority, Inc.

The fund's distribution agreement calls for FDC to use all reasonable efforts, consistent with its other business, to secure purchasers for shares of the fund, which are continuously offered.

Promotional and administrative expenses in connection with the offer and sale of shares are paid by FMR.

The Trustees have approved a Distribution and Service Plan on behalf of Class OUS of the fund (the Plan) pursuant to Rule 12b-1 under the 1940 Act (the Rule).

The Rule provides in substance that a fund may not engage directly or indirectly in financing any activity that is primarily intended to result in the sale of shares of the fund except pursuant to a plan approved on behalf of the fund under the Rule.

The Plan, as approved by the Trustees, allows shares of the fund and/or FMR to incur certain expenses that might be considered to constitute indirect payment by the fund of distribution expenses.

The Plan adopted for the fund or class, as applicable, is described in the prospectus.

Under the Plan, if the payment of management fees by the fund to FMR is deemed to be indirect financing by the fund of the distribution of its shares, such payment is authorized by the Plan.

The Plan specifically recognizes that FMR may use its management fee revenue, as well as its past profits or its other resources, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of shares of the fund and/or shareholder support services. In addition, the Plan provides that FMR, directly or through FDC, may pay significant amounts to intermediaries that provide those services.

Currently, the Board of Trustees has authorized such payments for shares of the fund.

Prior to approving the Plan, the Trustees carefully considered all pertinent factors relating to the implementation of the Plan, and determined that there is a reasonable likelihood that the Plan will benefit the fund or class, as applicable, and its shareholders.

In particular, the Trustees noted that the Plan does not authorize payments by shares of the fund other than those made to FMR under its management contract with the fund.

To the extent that the Plan gives FMR and FDC greater flexibility in connection with the distribution of shares, additional sales of shares or stabilization of cash flows may result.

Furthermore, certain shareholder support services may be provided more effectively under the Plan by local entities with whom shareholders have other relationships.

FDC or an affiliate may compensate, or upon direction make payments for certain retirement plan expenses to intermediaries. A number of factors are considered in determining whether to pay these additional amounts. Such factors may include, without limitation, the level or type of services provided by the intermediary, the level or expected level of assets or sales of shares, and other factors. In addition to such payments, FDC or an affiliate may offer other incentives such as sponsorship of educational or client seminars relating to current products and issues, payments or reimbursements for travel and related expenses associated with due diligence trips that an intermediary may undertake in order to explore possible business relationships with affiliates of FDC, and/or payments of costs and expenses associated with attendance at seminars, including travel, lodging, entertainment, and meals. Certain of the payments described above may be significant to an intermediary. As permitted by SEC and Financial Industry Regulatory Authority rules and other applicable laws and regulations, FDC or an affiliate may pay or allow other incentives or payments to intermediaries.

The fund's transfer agent or an affiliate may also make payments and reimbursements from its own resources to certain intermediaries (who may be affiliated with the transfer agent) for providing recordkeeping and administrative services to plan participants or for providing other services to retirement plans. Please see "Transfer and Service Agent Services" in this SAI for more information.

FDC or an affiliate may also make payments to banks, broker-dealers and other service-providers (who may be affiliated with FDC) for distribution-related activities and/or shareholder services. If you have purchased shares of the fund through an investment professional, please speak with your investment professional to learn more about any payments his or her firm may receive from FMR, FDC, and/or their affiliates, as well as fees and/or commissions the investment professional charges. You should also consult disclosures made by your investment professional at the time of purchase.

Any of the payments described in this section may represent a premium over payments made by other fund families. Investment professionals may have an added incentive to sell or recommend a fund over others offered by competing fund families, or retirement plan sponsors may take these payments into account when deciding whether to include a fund as a plan investment option.

TRANSFER AND SERVICE AGENT SERVICES

For purposes of the following "Transfer and Service Agent Services" discussion, the term "shares" (as it relates to the fund) means the one class of shares of the fund offered through the prospectus to which this SAI relates.

The fund has entered into a transfer agent agreement with Fidelity Investments Institutional Operations Company LLC (FIIOC), an affiliate of FMR, which is located at 245 Summer Street, Boston, Massachusetts 02210. Under the terms of the agreement, FIIOC (or an agent, including an affiliate) performs transfer agency services.

For providing transfer agency services, FIIOC receives no fees from the fund.

FIIOC may collect fees charged in connection with providing certain types of services such as exchanges, closing out fund balances, checkwriting, wire transactions, and providing historical account research, as applicable.

In addition, FIIOC receives the pro rata portion of the transfer agency fees applicable to shareholder accounts in a qualified tuition program (QTP), as defined under the Small Business Job Protection Act of 1996, managed by FMR or an affiliate and in certain funds of funds managed by FMR, according to the percentage of the QTP's, or a fund of funds' assets that is invested in the fund.

FIIOC bears the expense of typesetting, printing, and mailing prospectuses, statements of additional information, and all other reports, notices, and statements to existing shareholders, with the exception of proxy statements.

Fund shares may be owned by intermediaries for the benefit of their customers. In those instances, a fund may not maintain an account for shareholders, and some or all of the recordkeeping services for these accounts may be performed by third parties. FIIOC or an affiliate may make payments to intermediaries (including affiliates of FIIOC) for recordkeeping and other services.

Retirement plans may also hold fund shares in the name of the plan or its trustee, rather than the plan participant. In situations where FIIOC or an affiliate does not provide recordkeeping services, plan recordkeepers, who may have affiliated financial intermediaries who sell shares of the fund, may, upon direction, be paid for providing recordkeeping services to plan participants. Payments may also be made, upon direction, for other plan expenses. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

In certain situations where FIIOC or an affiliate provides recordkeeping services to a retirement plan, payments may be made to pay for plan expenses. The amount of such payments may be based on investments in particular Fidelity® funds, or may be fixed for a given period of time. Upon direction, payments may be made to plan sponsors, or at the direction of plan sponsors, third parties, for expenses incurred in connection with the plan. FIIOC may also pay an affiliate for providing services that otherwise would have been performed by FIIOC.

The fund has entered into a service agent agreement with Fidelity Service Company, Inc. (FSC), an affiliate of FMR (or an agent, including an affiliate). Under the terms of the agreement, FSC calculates the NAV and dividends for shares, maintains the fund's portfolio and general accounting records, and administers the fund's securities lending program, if applicable.

For providing pricing and bookkeeping services, FSC receives no fee from the fund.

FMR bears the cost of transfer agency services and pricing and bookkeeping services under the terms of its management contract with the fund.

DESCRIPTION OF THE TRUST

Trust Organization.

Fidelity® Treasury Only Money Market Fund is a fund of Fidelity Hereford Street Trust, an open-end management investment company created under an initial trust instrument dated November 18, 1993.

The Trustees are permitted to create additional funds in the trust and to create additional classes of a fund.

The assets of the trust received for the issue or sale of shares of each fund and all income, earnings, profits, and proceeds thereof, subject to the rights of creditors, are allocated to such fund, and constitute the underlying assets of such fund. The underlying assets of each fund in the trust shall be charged with the liabilities and expenses attributable to such fund, except that liabilities and expenses may be allocated to a particular class. Any general expenses of the trust shall be allocated between or among any one or more of the funds or classes.

Shareholder Liability. The trust is a statutory trust organized under Delaware law. Delaware law provides that, except to the extent otherwise provided in the Trust Instrument, shareholders shall be entitled to the same limitations of personal liability extended to stockholders of private corporations for profit organized under the general corporation law of Delaware. The courts of some states, however, may decline to apply Delaware law on this point. The Trust Instrument contains an express disclaimer of shareholder liability for the debts, liabilities, obligations, and expenses of the trust. The Trust Instrument provides that the trust shall not have any claim against shareholders except for the payment of the purchase price of shares and requires that each agreement, obligation, or instrument entered into or executed by the trust or the Trustees relating to the trust or to a fund shall include a provision limiting the obligations created thereby to the trust or to one or more funds and its or their assets. The Trust Instrument further provides that shareholders of a fund shall not have a claim on or right to any assets belonging to any other fund.

The Trust Instrument provides for indemnification out of a fund's property of any shareholder or former shareholder held personally liable for the obligations of the fund solely by reason of his or her being or having been a shareholder and not because of his or her acts or omissions or for some other reason. The Trust Instrument also provides that a fund shall, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the fund and satisfy any judgment thereon. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which Delaware law does not apply, no contractual limitation of liability was in effect, and a fund is unable to meet its obligations. Fidelity Management & Research Company LLC believes that, in view of the above, the risk of personal liability to shareholders is extremely remote.

Claims asserted against one class of shares may subject holders of another class of shares to certain liabilities.

Voting Rights. The fund's capital consists of shares of beneficial interest. Shareholders are entitled to one vote for each dollar of net asset value they own. The voting rights of shareholders can be changed only by a shareholder vote. Shares may be voted in the aggregate, by fund, and by class.

The shares have no preemptive or conversion rights. Shares are fully paid and nonassessable, except as set forth under the heading "Shareholder Liability" above.

The trust or a fund or a class may be terminated upon the sale of its assets to, or merger with, another open-end management investment company, series, or class thereof, or upon liquidation and distribution of its assets. The Trustees may reorganize, terminate, merge, or sell all or a portion of the assets of a trust or a fund or a class without prior shareholder approval. In the event of the dissolution or liquidation of a trust, shareholders of each of its funds are entitled to receive the underlying assets of such fund available for distribution. In the event of the dissolution or liquidation of a fund or a class, shareholders of that fund or that class are entitled to receive the underlying assets of the fund or class available for distribution.

Custodian(s).

Citibank, N.A., 388 Greenwich Street, New York, New York, is custodian of the assets of the fund.

The custodian is responsible for the safekeeping of the fund's assets and the appointment of any subcustodian banks and clearing agencies.

From time to time, subject to approval by a fund's Treasurer, a Fidelity® fund may enter into escrow arrangements with other banks if necessary to participate in certain investment offerings.

FMR, its officers and directors, its affiliated companies, Members of the Advisory Board (if any), and Members of the Board of Trustees may, from time to time, conduct transactions with various banks, including banks serving as custodians for certain funds advised by FMR or an affiliate. Transactions that have occurred to date include mortgages and personal and general business loans. In the judgment of the fund's adviser, the terms and conditions of those transactions were not influenced by existing or potential custodial or other fund relationships.

Independent Registered Public Accounting Firm.

[_____________________], independent registered public accounting firm, audits financial statements for the fund and provides other audit, tax, and related services.

FUND HOLDINGS INFORMATION

The fund views holdings information as sensitive and limits its dissemination. The Board authorized FMR to establish and administer guidelines for the dissemination of fund holdings information, which may be amended at any time without prior notice. FMR's Executive Holdings Policy Committee (comprising executive officers of FMR) evaluates disclosure policy with the goal of serving the fund's best interests by striking an appropriate balance between providing information about the fund's portfolio and protecting the fund from potentially harmful disclosure. The Board reviews the administration and modification of these guidelines and receives reports from the fund's chief compliance officer periodically.

The fund will provide a full list of holdings as of the last day of the previous month on www.fidelity.com. This information will be provided monthly by no later than the fifth business day of each month. The information will be available on the web site for a period of not less than six months.

A full list of holdings may be obtained from the fund more frequently, including daily, upon request. A full list of the fund's holdings (as of the previous business day) may also be obtained on a continuous basis by submitting a standing request to the fund. The fund may also from time to time provide or make available to third parties upon request specific fund level performance attribution information and statistics, or holdings information with respect to a specific security or company. Third parties may include fund shareholders or prospective fund shareholders, members of the press, consultants, and ratings and ranking organizations. FMR reserves the right to refuse to fulfill any request for portfolio holdings information if it believes that providing such information may adversely affect the fund or its shareholders. Nonexclusive examples of performance attribution information and statistics may include (i) the allocation of the fund's portfolio holdings and other investment positions among various asset classes, sectors, industries, and countries, (ii) the characteristics of the stock and bond components of the fund's portfolio holdings and other investment positions, (iii) the attribution of fund returns by asset class, sector, industry, and country and (iv) the volatility characteristics of the fund.

FMR's Executive Holdings Policy Committee may approve a request for fund level performance attribution and statistics as long as (i) such disclosure does not enable the receiving party to recreate the complete or partial portfolio holdings of any Fidelity® fund prior to such fund's public disclosure of its portfolio holdings and (ii) Fidelity has made a good faith determination that the requested information is not material given the particular facts and circumstances. Fidelity may deny any request for performance attribution information and other statistical information about a fund made by any person, and may do so for any reason or for no reason.

Disclosure of non-public portfolio holdings information for a Fidelity® fund's portfolio may only be provided pursuant to the guidelines below.

The Use of Holdings In Connection With Fund Operations. Material non-public holdings information may be provided as part of the activities associated with managing Fidelity® funds to: entities which, by explicit agreement or by virtue of their respective duties to the fund, are required to maintain the confidentiality of the information disclosed; other parties if legally required; or persons FMR believes will not misuse the disclosed information. These entities, parties, and persons include, but are not limited to: the fund's trustees; the fund's manager, its sub-advisers, if any, and their affiliates whose access persons are subject to a code of ethics (including portfolio managers of affiliated funds of funds); contractors who are subject to a confidentiality agreement; the fund's auditors; the fund's custodians; proxy voting service providers; financial printers; pricing service vendors; broker-dealers in connection with the purchase or sale of securities or requests for price quotations or bids on one or more securities; securities lending agents; counsel to the fund or its Independent Trustees; regulatory authorities; stock exchanges and other listing organizations; parties to litigation; third parties in connection with a bankruptcy proceeding relating to a fund holding; and third parties who have submitted a standing request to a money market fund for daily holdings information. Non-public holdings information may also be provided to an issuer regarding the number or percentage of its shares that are owned by the fund and in connection with redemptions in kind.

Other Uses Of Holdings Information. In addition, the fund may provide material non-public holdings information to (i) third parties that calculate information derived from holdings for use by FMR, a sub-adviser, or their affiliates, (ii) ratings and rankings organizations, and (iii) an investment adviser, trustee, or their agents to whom holdings are disclosed for due diligence purposes or in anticipation of a merger involving the fund. Each individual request is reviewed by the Executive Holdings Policy Committee which must find, in its sole discretion that, based on the specific facts and circumstances, the disclosure appears unlikely to be harmful to the fund. Entities receiving this information must have in place control mechanisms to reasonably ensure or otherwise agree that, (a) the holdings information will be kept confidential, (b) no employee shall use the information to effect trading or for their personal benefit, and (c) the nature and type of information that they, in turn, may disclose to third parties is limited. FMR relies primarily on the existence of non-disclosure agreements and/or control mechanisms when determining that disclosure is not likely to be harmful to the fund.

At this time, the entities receiving information described in the preceding paragraph are: Factset Research Systems Inc. (full or partial fund holdings daily, on the next business day); Standard & Poor's Ratings Services (full holdings weekly (generally as of the previous Friday), generally 5 business days thereafter); MSCI Inc. and certain affiliates (full or partial fund holdings daily, on the next business day); and Bloomberg, L.P. (full holdings daily, on the next business day).

FMR, its affiliates, or the fund will not enter into any arrangements with third parties from which they derive consideration for the disclosure of material non-public holdings information. If, in the future, such an arrangement is desired, prior Board approval would be sought and any such arrangements would be disclosed in the fund's SAI.

There can be no assurance that the fund's policies and procedures with respect to disclosure of fund portfolio holdings will prevent the misuse of such information by individuals and firms that receive such information.

FINANCIAL STATEMENTS 

The fund's financial statements and financial highlights for the fiscal year ended April 30, 2024, and report of the independent registered public accounting firm, are included in the fund's Form N-CSR and are incorporated herein by reference. 

Financial highlights for Class OUS of the fund will be included in the fund's Form N-CSR when the class has completed its first annual period.

Total annual operating expenses as shown in the prospectus fee table may differ from the ratios of expenses to average net assets in the financial highlights because total annual operating expenses as shown in the prospectus fee table include any acquired fund fees and expenses, whereas the ratios of expenses in the financial highlights do not, except to the extent any acquired fund fees and expenses relate to an entity, such as a wholly-owned subsidiary, with which a fund's financial statements are consolidated. Acquired funds include other investment companies (such as Central funds or other underlying funds) in which the fund has invested, if and to the extent it is permitted to do so.

Total annual operating expenses in the prospectus fee table and the financial highlights do not include any expenses associated with investments in certain structured or synthetic products that may rely on the exception from the definition of "investment company" provided by section 3(c)(1) or 3(c)(7) of the 1940 Act.

Item 29.

Persons Controlled by or under Common Control with the Trust

The Board of Trustees of the Trust is the same as the board of other Fidelity funds, each of which has Fidelity Management & Research Company LLC, or an affiliate, or Geode Capital Management LLC, as its investment adviser. In addition, the officers of the Trust are substantially identical to those of the other Fidelity funds. Nonetheless, the Trust takes the position that it is not under common control with other Fidelity funds because the power residing in the respective boards and officers arises as the result of an official position with the respective trusts.

Item 30.

Indemnification

Pursuant to Del. Code Ann. title 12 § 3817, a Delaware statutory trust may provide in its governing instrument for the indemnification of its officers and trustees from and against any and all claims and demands whatsoever. Article X, Section 10.02 of the Trust Instrument sets forth the reasonable and fair means for determining whether

indemnification shall be provided to any past or present Trustee or officer. It states that the Trust shall indemnify any present or past trustee or officer to the fullest extent permitted by law against liability, and all expenses reasonably incurred by him or her in connection with any claim, action, suit or proceeding in which he or she is involved by virtue of his or her service as a trustee or officer and against any amount incurred in settlement thereof. Indemnification will not be provided to a person adjudged by a court or other adjudicatory body to be liable to the Trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties (collectively, “disabling conduct”), or not to have acted in good faith in the reasonable belief that his or her action was in the best interest of the Trust. In the event of a settlement, no indemnification may be provided unless there has been a determination, as specified in the Trust Instrument, that the officer or trustee did not engage in disabling conduct.

Pursuant to Section 11 of the Distribution Agreement, the Trust agrees to indemnify and hold harmless the Distributor and each of its directors and officers and each person, if any, who controls the Distributor within the meaning of Section 15 of the 1933 Act against any loss, liability, claim, damages or expense (including the reasonable cost of investigating or defending any alleged loss, liability, claim, damages, or expense and reasonable counsel fees incurred in connection therewith) arising by reason of any person acquiring any shares, based upon the ground that the registration statement, Prospectus, Statement of Additional Information, shareholder reports or other information filed or made public by the Trust (as from time to time amended) included an untrue statement of a material fact or omitted to state a material fact required to be stated or necessary in order to make the statements not misleading under the 1933 Act, or any other statute or the common law. However, the Trust does not agree to indemnify the Distributor or hold it harmless to the extent that the statement or omission was made in reliance upon, and in conformity with, information furnished to the Trust by or on behalf of the Distributor. In no case is the indemnity of the Trust in favor of the Distributor or any person indemnified to be deemed to protect the Distributor or any person against any liability to the Issuer or its security holders to which the Distributor or such person would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

Pursuant to the agreement by which Fidelity Investments Institutional Operations Company LLC (“FIIOC”) is appointed transfer agent, the Registrant agrees to indemnify and hold FIIOC harmless against any losses, claims, damages, liabilities or expenses (including reasonable counsel fees and expenses) resulting from:

(1)

any claim, demand, action or suit brought by any person other than the Registrant, including by a shareholder, which names FIIOC and/or the Registrant as a party and is not based on and does not result from FIIOC’s willful misfeasance, bad faith or negligence or reckless disregard of duties, and arises out of or in connection with FIIOC’s performance under the Transfer Agency Agreement; or

(2)

any claim, demand, action or suit (except to the extent contributed to by FIIOC’s willful misfeasance, bad faith or negligence or reckless disregard of duties) which results from the negligence of the Registrant, or from FIIOC’s acting upon any instruction(s) reasonably believed by it to have been executed or communicated by any person

duly authorized by the Registrant, or as a result of FIIOC’s acting in reliance upon advice reasonably believed by FIIOC to have been given by counsel for the Registrant, or as a result of FIIOC’s acting in reliance upon any instrument or stock certificate reasonably believed by it to have been genuine and signed, countersigned or executed by the proper person.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant, the Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.
