Fund Summary
Fund:
Fidelity Flex® Conservative Income Municipal Bond Fund
Investment Objective

AThe fund is available only to certain fee-based accounts and advisory programs offered by Fidelity. Advisory account clients, retirement plans, plan sponsors and/or plan participants typically pay an advisory fee that generally covers investment advisory and administrative services.
BFidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse the fund to the extent proxy and shareholder meeting expenses exceed 0.003% of the fund's average net assets. This arrangement will remain in effect through April 30, 2025. FMR may not terminate this arrangement before the expiration date without the approval of the Board of Trustees and may extend it in its discretion after that date.
This example helps compare the cost of investing in the fund with the cost of investing in other funds.
Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. This example does not include any fees paid at the fee-based account or plan level. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

Portfolio Turnover
The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 78% of the average value of its portfolio.
Principal Investment Strategies
  • Normally investing at least 80% of assets in U.S. dollar-denominated municipal money market securities and high quality investment-grade municipal debt securities whose interest is exempt from federal income tax.
  • Managing the fund to have similar overall interest rate risk to the supplemental index.
  • Normally maintaining a dollar-weighted average maturity of one year or less.
  • Normally investing in securities with a maximum maturity of four years.
  • Allocating assets across different market sectors and maturities.
  • Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
  • Analyzing the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
Principal Investment Risks
  • Municipal Market Volatility.
The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.
  • Interest Rate Changes.
Interest rate increases can cause the price of a debt or money market security to decrease.
  • Issuer-Specific Changes.
The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a security to decrease.
An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.
Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate.
Performance
The following information is intended to help you understand the risks of investing in the fund.
The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index and a hypothetical composite of market indexes over various periods of time. The indexes have characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.
The performance shown does not reflect the impact of any fees paid at the fee-based account or plan level.

These payments may create a conflict of interest by influencing your intermediary and your investment professional to recommend the fund over another investment. Currently, the Board of Trustees of the fund has not authorized such payments for shares of the fund. Ask your investment professional or visit your intermediary's web site for more information.
 
Fund Basics
Investment Details
Investment Objective
Fidelity Flex® Conservative Income Municipal Bond Fund seeks to provide a high level of income, exempt from federal income tax, consistent with preservation of capital.
Principal Investment Strategies
The Adviser normally invests at least 80% of the fund's assets in U.S. dollar-denominated municipal money market securities and high quality investment-grade municipal debt securities whose interest is exempt from federal income tax. The Adviser may invest all of the fund's assets in municipal securities whose interest is subject to the federal alternative minimum tax.
The Adviser uses 50% Bloomberg Municipal Bond 1 Year (1-2 Y) Index / 50% iMoneyNetSM All Tax-Free National Retail Money Market Funds Average as a guide in structuring the fund and selecting its investments. The Adviser manages the fund to have similar overall interest rate risk to the index.
The Adviser considers other factors when selecting the fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the fund's exposure to various risks, including interest rate risk, the Adviser considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, and internal views of potential future market conditions.
In addition, the fund normally maintains a dollar-weighted average maturity of one year or less. As of December 31, 2023, the fund's dollar-weighted average maturity was approximately 0.8 years and the customized municipal bond index's dollar-weighted average maturity was approximately 0.8 years.
The Adviser normally invests the fund's assets in securities with a maximum maturity of four years.
The Adviser allocates the fund's assets among different market sectors (for example, general obligation bonds of a state or bonds financing a specific project) and different maturities based on its view of the relative value of each sector or maturity.
The Adviser may invest more than 25% of the fund's total assets in municipal securities that finance similar projects, such as those relating to education, health care, transportation, and utilities.
If the Adviser's strategies do not work as intended, the fund may not achieve its objective.
Description of Principal Security Types
Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Some debt securities, such as zero coupon bonds, do not pay current interest but are sold at a discount from their face values. Municipal debt securities include general obligation bonds of municipalities, local or state governments, project or revenue-specific bonds, or pre-refunded or escrowed bonds, municipal money market securities, and other securities believed to have debt-like characteristics, including hybrids and synthetic securities. 
Money market securities are high-quality, short-term securities that pay a fixed, variable, or floating interest rate. Securities are often specifically structured so that they are eligible investments for a money market fund. For example, in order to satisfy the maturity restrictions for a money market fund, some money market securities have demand or put features, which have the effect of shortening the security's maturity. Money market securities include bank certificates of deposit, bankers' acceptances, bank time deposits, notes, commercial paper, and U.S. Government securities. 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. 
Municipal securities are issued to raise money for a variety of public and private purposes, including general financing for state and local governments, or financing for a specific project or public facility. Municipal securities may be fully or partially backed by the local government, by the credit of a private issuer, by the current or anticipated revenues from a specific project or specific assets, or by domestic or foreign entities providing credit support such as letters of credit, guarantees, or insurance.
Derivatives are investments whose values are tied to an underlying asset, instrument, currency, or index. Derivatives include futures, options, forwards, and swaps, such as interest rate swaps (exchanging a floating rate for a fixed rate), total return swaps (exchanging a floating rate for the total return of an index, security, or other instrument or investment) and credit default swaps (buying or selling credit default protection).
Forward-settling securities involve a commitment to purchase or sell specific securities when issued, or at a predetermined price or yield. Payment and delivery take place after the customary settlement period.
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 share price and yield change daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. The fund's reaction to these developments will be affected by the types and maturities of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.
The following factors can significantly affect the fund's performance:
Municipal Market Volatility. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes, or the rights of municipal security holders. Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation, and utilities, conditions in those sectors can affect the overall municipal market. Budgetary constraints of local, state, and federal governments upon which the issuers may be relying for funding may also impact municipal securities. In addition, changes in the financial condition of an individual municipal insurer can affect the overall municipal market, and market conditions may directly impact the liquidity and valuation of municipal securities.
Interest Rate Changes. Debt securities, including money market securities, have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities can be more sensitive to interest rate changes, meaning the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. Short-term and long-term interest rates do not necessarily move in the same amount or the same direction. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Securities with floating interest rates can be less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much as interest rates in general. 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. Although the transition process away from certain benchmark rates, including London Interbank Offered Rate (LIBOR) (an indicative measure of the average interest rate at which major global banks could borrow from one another), has become increasingly well-defined, 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.
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 security or 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. Entities providing credit support or a maturity-shortening structure also can be affected by these types of changes, and if the structure of a security fails to function as intended, the security could decline in value. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service (IRS) determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline significantly in value.
Generally, the fund purchases municipal securities whose interest, in the opinion of bond counsel, is free from federal income tax. Neither the Adviser nor the fund guarantees that this opinion is correct, and there is no assurance that the IRS will agree with bond counsel's opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with federal tax requirements to preserve the tax- free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued. For certain types of structured securities, the tax status of the pass- through of tax- free income may also be based on the federal tax treatment of the structure.
Leverage Risk. Derivatives and forward-settling securities involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Leverage can magnify investment risks and cause losses to be realized more quickly. A small change in the underlying asset, instrument, or index can lead to a significant loss. Forward-settling securities also involve the risk that a security will not be issued, delivered, or paid for when anticipated. Government legislation or regulation could affect the use of these transactions and could limit a fund's ability to pursue its investment strategies.
In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy for defensive purposes. If the fund does so, different factors could affect its performance, and the fund could distribute income subject to federal income tax.
Other Investment Strategies
In addition to the principal investment strategies discussed above, the Adviser may invest the fund's assets in municipal debt securities by investing in other funds.
The Adviser may invest the fund's assets in lower quality investment-grade securities.
The Adviser may also engage in transactions that have a leveraging effect on the fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, or components of the index underlying the derivative, and forward-settling securities. The fund's derivative investments may include futures contracts (both long and short positions) on securities and indexes. Depending on the Adviser's outlook and market conditions, the Adviser may engage in these transactions to increase or decrease the fund's exposure to changing security prices, interest rates, credit qualities, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, or index.
 
Fundamental Investment Policies
The following is fundamental, that is, subject to change only by shareholder approval:
Fidelity Flex® Conservative Income Municipal Bond Fund seeks to provide a high level of income, exempt from federal income tax, consistent with preservation of capital. The fund normally invests at least 80% of its assets in U.S. dollar-denominated municipal money market securities and high quality investment-grade municipal debt securities whose interest is exempt from federal income tax.
 
 
 
 
Valuing Shares
The fund is open for business each day the NYSE is open.
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.
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.
NAV is calculated using the values of other open-end funds, if any, in which the fund invests (referred to as underlying funds). Shares of underlying funds are valued at their respective NAVs. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.
Arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before a fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets, if applicable, present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas markets but prior to the close of the U.S. market. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of NAV by short-term traders.
Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.
 
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
Ways to Invest
Shares can be purchased only through certain fee-based accounts and advisory programs offered by Fidelity, including certain employer-sponsored plans and discretionary investment programs. 
Information on Placing Orders
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 or exchange, 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 brokerage commissions or spreads paid to dealers who sell money market instruments), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.
The fund generally invests in liquid money market and short-duration debt securities and the Adviser anticipates that shareholders may purchase and sell shares of the fund frequently. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive trading of fund shares and the fund accommodates frequent trading. 
The fund has no limit on purchase or exchange 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 exchanges or impose conditions that are more restrictive on excessive trading than those stated in this prospectus.  
Buying Shares
Eligibility
Shares are generally available only to investors residing in the United States.
Shares are available only to certain fee-based accounts and advisory programs offered by Fidelity.
Shares also may be available to certain broker-dealers that have entered into arrangements with Fidelity.
There is no minimum balance or purchase minimum for fund shares.
Shares of the fund are not eligible for purchase by registered investment companies or business development companies to the extent such acquisition is in reliance on Rule 12d1-4 under the Investment Company Act of 1940.
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.
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.
A signature guarantee is designed to protect you and Fidelity from fraud. Fidelity may require that your request be made in writing and include a signature guarantee in certain circumstances, such as:
You should be able to obtain a signature guarantee from a bank, broker (including Fidelity® Investor Centers), dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.
When you place an order to sell shares, note the following:
Policies Concerning the Redemption of Fund Shares
Shares of the fund are only available to certain fee-based accounts and advisory programs offered by Fidelity.
A fund typically expects to pay redemption proceeds on the next business day following receipt of a redemption order in proper form. Proceeds from the periodic and automatic sale of shares of a Fidelity® money market fund that are used to buy shares of another Fidelity® fund are settled simultaneously.
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. 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.
When your relationship with your managed account adviser or retirement plan sponsor is terminated, your shares may be sold at the NAV next calculated, in which case the redemption proceeds will remain in your account pending your instruction. Withdrawing your investment could have tax consequences for you.
Exchanging Shares (for Retirement Plans Only)
An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.
Shares may be exchanged into shares of any Fidelity Flex® fund available through your plan.
However, you should note the following policies and restrictions governing exchanges:
The fund may terminate or modify exchange privileges in the future.
Rollover IRAs (for Retirement Plans Only)
Shares of the fund are not available to IRA rollover accounts. When your relationship with your retirement plan sponsor is terminated, your shares may be sold at the NAV next calculated. Withdrawing your investment could have tax consequences for you.
Account Policies
The following apply to you as a shareholder.
Statements that Fidelity sends to you, if applicable, include the following:
You may initiate many transactions by telephone or electronically. Fidelity will not be responsible for any loss, cost, expense, or other liability resulting from unauthorized transactions if it follows reasonable security procedures designed to verify the identity of the investor. Fidelity will request personalized security codes or other information, and may also record calls. For transactions conducted through the Internet, Fidelity recommends the use of an Internet browser with 128-bit encryption. You should verify the accuracy of your confirmation statements upon receipt and notify Fidelity immediately of any discrepancies in your account activity. If you do not want the ability to sell and exchange by telephone, call Fidelity for instructions. Additional documentation may be required from corporations, associations, and certain fiduciaries.
You may be asked to provide additional information in order for Fidelity to verify your identity in accordance with requirements under anti-money laundering regulations. 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 also realizes capital gains from its investments, and distributes these gains (less any losses) to shareholders as capital gain distributions.
The fund normally declares dividends and pays capital gain distributions per the tables below:

Tax Consequences
As with any investment, your investment in the fund could have tax consequences for you (for non-retirement accounts).
Taxes on Distributions
The fund seeks to earn income and pay dividends exempt from federal income tax.
Income exempt from federal income tax may be subject to state or local tax. A portion of the dividends you receive may be subject to federal and state income taxes and may also be subject to the federal alternative minimum tax. You may also receive taxable distributions attributable to the fund's sale of municipal bonds.
For federal tax purposes, certain distributions, including distributions of short-term capital gains and gains on the sale of bonds characterized as market discount, are taxable to you as ordinary income, while certain distributions of long-term capital gains are taxable to you generally as capital gains.
If you buy shares when a fund has realized but not yet distributed income or capital gains, you will be "buying a dividend" by paying the full price for the shares and then receiving a portion of the price back in the form of a potentially taxable distribution.
Any taxable distributions you receive from the fund will normally be taxable to you when you receive them.
If you elect to receive distributions in cash, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.
Taxes on Transactions
Your redemptions may result in a capital gain or loss for federal tax purposes (for non-retirement accounts). A capital gain or loss on your investment in the fund generally is the difference between the cost of your shares and the price you receive when you sell them. Exchanges within a tax-advantaged retirement plan account will not result in a capital gain or loss for federal tax purposes. Please consult your tax advisor regarding the tax treatment of distributions from a tax-advantaged retirement plan account.

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.

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.

Fund Distribution
FDC distributes the fund's 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 fund shares.
These payments are described in more detail in this section and in the SAI.
Distribution and Service Plan(s)
The fund has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act) with respect to its shares 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 shares of the fund 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 not authorized such payments for shares of the fund.
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 fund's assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.
From time to time, FDC may offer special promotional programs to investors who purchase shares of Fidelity® funds. For example, FDC may offer merchandise, discounts, vouchers, or similar items to investors who purchase shares of certain Fidelity® funds during certain periods. To determine if you qualify for any such programs, contact Fidelity or visit our web site at www.fidelity.com.

If given or made, such other information or representations must not be relied upon as having been authorized by the fund or FDC.
