Fund Summary
Fund:
Fidelity® SAI Low Duration Income Fund
Investment Objective
Fidelity® SAI Low Duration Income Fund seeks to obtain a high level of current income consistent with preservation of capital.
Fee Table
The following table describes the fees and expenses that may be incurred when you buy, hold, and sell shares of the fund.
 
Shareholder fees
(fees paid directly from your investment)
None
Annual Operating Expenses
(expenses that you pay each year as a % of the value of your investment)
Management fee

0.01%   B
Total annual operating expenses after fee waiver and/or expense reimbursement

AAdjusted to reflect current fees.
BFidelity Management & Research Company LLC (FMR) has contractually agreed to reimburse the fund to the extent that total operating expenses (excluding interest, certain taxes, fees and expenses of the Independent Trustees, proxy and shareholder meeting expenses, extraordinary expenses, and acquired fund fees and expenses (including fees and expenses associated with a wholly owned subsidiary), if any, as well as non-operating expenses such as brokerage commissions and fees and expenses associated with the fund's securities lending program, if applicable), as a percentage of its average net assets, exceed 0.20% (the Expense Cap). If at any time during the current fiscal year expenses for the fund fall below the Expense Cap, FMR reserves the right to recoup through the end of the fiscal year any expenses that were reimbursed during the current fiscal year up to, but not in excess of, the Expense Cap. This arrangement will remain in effect through December 31, 2024. 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. 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 46% of the average value of its portfolio.
Principal Investment Strategies
  • Normally investing at least 80% of assets in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities.
  • Normally maintaining a duration of 1 year or less.
  • Managing the fund to have similar overall interest rate risk to the Bloomberg US Treasury Bill: 6-9 Months Index.
  • Normally maintaining a dollar-weighted average maturity of two years or less.
  • Allocating assets across different market sectors and maturities.
  • Investing more than 25% of total assets in the financial services industries.
  • Investing in domestic and foreign issuers.
  • Analyzing the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.
  • Engaging in transactions that have a leveraging effect on the fund, including investments in derivatives - such as swaps (interest rate, total return, and credit default), options, and futures contracts - and forward-settling securities, to adjust the fund's risk exposure.
Principal Investment Risks
  • Interest Rate Changes.
Interest rate increases can cause the price of a debt security to decrease.
  • Foreign Exposure.
Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
  • Financial Services Concentration.
Changes in government regulation and interest rates and economic downturns can have a significant negative effect on issuers in the financial services sector, including the price of their securities or their ability to meet their payment obligations.
  • Prepayment.
The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.
  • 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.
  • Leverage Risk.
Leverage can increase market exposure, magnify investment risks, and cause losses to be realized more quickly.
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 over various periods of time.

Investment Details
 
Investment Objective

Principal Investment Strategies
The Adviser normally invests at least 80% of the fund's assets in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities.
The fund normally maintains a duration of 1 year or less. Duration is a measure of a bond's price sensitivity to a change in interest rates. For example, if a bond has a 1-year duration and interest rates rise 1%, the bond's value is likely to fall about 1%. Similarly, if a bond fund has a 1-year duration and interest rates rise 1%, the fund's value is likely to fall about 1%.
The Adviser uses the Bloomberg US Treasury Bill: 6-9 Months Index 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 two years or less. As of August 31, 2023, the fund's dollar-weighted average maturity was approximately 0.8 years and the index's dollar-weighted average maturity was approximately 0.6 years. In determining a security's maturity for purposes of calculating the fund's average maturity, an estimate of the average time for its principal to be paid may be used. This can be substantially shorter than its stated maturity.
The Adviser allocates the fund's assets among different market sectors (for example, corporate, asset-backed, or government securities) and different maturities based on its view of the relative value of each sector or maturity.
The Adviser will invest more than 25% of the fund's total assets in the financial services industries.
The Adviser may invest the fund's assets in securities of foreign issuers in addition to securities of domestic issuers.
The Adviser may 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 Adviser may invest a significant portion of the fund's assets in these types of investments. If the fund invests a significant portion of its assets in derivatives, its investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own. The fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, options (including options on futures and swaps), and futures contracts (both long and short positions) on securities, other instruments, 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.
If the Adviser's strategies do not work as intended, the fund may not achieve its objective.

In determining a security's maturity for purposes of calculating the fund's average maturity, an estimate of the average time for its principal to be paid may be used. This can be substantially shorter than its stated maturity.
The Adviser allocates the fund's assets among different market sectors (for example, corporate, asset-backed, or government securities) and different maturities based on its view of the relative value of each sector or maturity.
To earn additional income for the fund, the Adviser may use a trading strategy that involves selling (or buying) mortgage securities and simultaneously agreeing to purchase (or sell) mortgage securities on a later date at a set price. This trading strategy may increase interest rate exposure and result in an increased portfolio turnover rate which increases transaction costs and may increase taxable gains.
The Adviser may invest the fund's assets in securities of foreign issuers in addition to securities of domestic issuers.
The Adviser may 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 Adviser may invest a significant portion of the fund's assets in these types of investments. If the fund invests a significant portion of its assets in derivatives, its investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own. The fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, options (including options on futures and swaps), and futures contracts (both long and short positions) on securities, other instruments, 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.
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. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities (including collateralized loan obligations), loans and loan participations, and other securities believed to have debt-like characteristics, including hybrids and synthetic securities.
A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price. 
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. When a fund does not already own or have the right to obtain securities equivalent in kind and amount, a commitment to sell securities is equivalent to a short sale. Payment and delivery take place after the customary settlement period.
Principal Investment Risks
Many factors affect each 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. A 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. A 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 a 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 a fund.
The following factors can significantly affect a fund's performance:
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 and certain types of securities, such as mortgage securities and the securities of issuers in the financial services sector, 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. Securities whose payment at maturity is based on the movement of all or part of an index and inflation-protected debt securities may react differently from other types of debt securities. 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.
Foreign Exposure. Foreign securities and securities issued by U.S. entities with substantial foreign operations can involve additional risks relating to political, economic, or regulatory conditions in foreign countries. These risks include fluctuations in foreign exchange rates; withholding or other taxes; trading, settlement, custodial, and other operational risks; and the less stringent investor protection and disclosure standards of some foreign markets. All of these factors can make foreign investments more volatile and potentially less liquid than U.S. investments. In addition, foreign markets can perform differently from the U.S. market.
Global economies and financial markets are becoming increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers or providers in, or foreign exchange rates with, a different country or region.
Financial Services Concentration. Financial services companies are highly dependent on the supply of short-term financing and can be sensitive to changes in government regulation and interest rates and to economic downturns in the United States and abroad. These events can significantly affect the price of issuers' securities as well as their ability to make payments of principal or interest or otherwise meet obligations on securities or instruments for which they serve as guarantors or counterparties.
Prepayment. Many types of debt securities, including mortgage securities, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security's maturity. Securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. In addition, the potential impact of prepayment features on the price of a debt security can be difficult to predict and result in greater volatility.
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. Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) tend to be more sensitive to these changes than higher-quality debt securities.
Leverage Risk. Derivatives, forward-settling securities, and short sale transactions 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 and short sale transactions also involve the risk that a security will not be issued, delivered, available for purchase, or paid for when anticipated. An increase in the market price of securities sold short will result in a loss. 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 may not achieve its investment objective.
Other Investment Strategies
In addition to the principal investment strategies discussed above, the Adviser may invest in collateralized loan obligations.

Shareholder Notice
The following is subject to change only upon 60 days' prior notice to shareholders:
Fidelity® SAI Low Duration Income Fund normally invests at least 80% of its assets in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities.
Fidelity® SAI Short-Term Bond Fund normally invests at least 80% of its assets in investment-grade debt securities (those of medium and high quality) of all types and repurchase agreements for those securities.
Valuing Shares
 
Each fund is open for business each day the NYSE is open.
The NAV is the value of a single share. Fidelity normally calculates NAV each business day as of the times noted in the table below. Each fund's assets normally are valued as of this time for the purpose of computing NAV.
Fund
NAV Calculation Times
(Eastern Time)
Fidelity® SAI Low Duration Income Fund
4:00 p.m.
Fidelity® SAI Short-Term Bond Fund
4:00 p.m.
NAV is not calculated and a 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 a 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 a 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 a 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
 
NOT AVAILABLE FOR SALE TO THE GENERAL PUBLIC.
As used in this prospectus, the term "shares" generally refers to the shares offered through this prospectus.
Shares are offered exclusively to certain clients of the Adviser or its affiliates. If you are not currently a client in a discretionary investment program offered by the Adviser or its affiliates, please call 1-800-544-3455 (9:00 a.m. - 6:00 p.m. Eastern time, Monday through Friday) for more information. Additional fees apply for discretionary investment programs. For more information on these fees, please refer to the "Buying and Selling Information" section of the Statement of Additional Information (SAI). 
A fund may reject for any reason, or cancel as permitted or required by law, any purchase orders.
Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to a 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.
Because investments in each fund can only be made by the Adviser or an affiliate on behalf of its clients, the potential for excessive or short-term disruptive purchases and sales is reduced. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive trading of fund shares and each fund accommodates frequent trading.  
Each fund does not place a limit on purchases or sales of fund shares by the Adviser or its affiliates. Each fund reserves the right, but does not have the obligation, to reject any purchase transaction at any time. In addition, each fund reserves the right to impose restrictions on disruptive, excessive, or short-term trading. 
Each fund has no exchange privilege with any other fund.
There is no minimum balance or purchase minimum for fund shares.
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.
Shares are generally available only to investors residing in the United States.
Each 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.
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 a fund.
See "Policies Concerning the Redemption of Fund Shares" below for additional redemption information.
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 a fund.
When you terminate your relationship with the Adviser, or one of its affiliates, your shares may be sold at the NAV next calculated, in which case proceeds from such redemption would be sent to you.
Under applicable anti-money laundering rules and other regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.
If applicable, orders by funds of funds for which the Adviser or its affiliates serve as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.
Policies Concerning the Redemption of Fund Shares
If your account is held directly with a fund, the length of time that a fund typically expects to pay redemption proceeds depends on the method you have elected to receive such proceeds. A fund typically expects to make payment of redemption proceeds by wire, automated clearing house (ACH) or by issuing a check by 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.
If your account is held through an intermediary, the length of time that a fund typically expects to pay redemption proceeds depends, in part, on the terms of the agreement in place between the intermediary and a fund. For redemption proceeds that are paid either directly to you from a fund or to your intermediary for transmittal to you, a fund typically expects to make payments by wire, by ACH or by issuing a check on the next business day following receipt of a redemption order in proper form from the intermediary by a fund. Redemption orders that are processed through investment professionals that utilize the National Securities Clearing Corporation will generally settle one to three business days 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. 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.
Dividends and Capital Gain Distributions
 
Each fund earns interest, dividends, and other income from its investments, and distributes this income (less expenses) to shareholders as dividends. Each fund also realizes capital gains from its investments, and distributes these gains (less any losses) to shareholders as capital gain distributions.
Each fund normally declares dividends and pays capital gain distributions per the tables below:
Fund Name
 
Dividends Paid
Fidelity® SAI Low Duration Income Fund
 
Declares daily and pays monthly
Fidelity® SAI Short-Term Bond Fund
 
Declares daily and pays monthly
Fund Name
 
Capital Gains Paid
Fidelity® SAI Low Duration Income Fund
 
October, December
Fidelity® SAI Short-Term Bond Fund
 
October, December
Earning Dividends 
A fund processes purchase and redemption requests only on days it is open for business. 
Shares generally begin to earn dividends on the first business day following the day of purchase. 
Shares generally earn dividends until, but not including, the next business day following the day of redemption. 
Distribution Options 
Any dividends and capital gain distributions may be reinvested in additional shares or paid in cash. 
Tax Consequences
 
As with any investment, your investment in a fund could have tax consequences for you (for non-retirement accounts).
Taxes on Distributions
Distributions you receive from each fund are subject to federal income tax, and may also be subject to state or local taxes.
For federal tax purposes, 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, are taxable to you generally as capital gains. Because a fund's income is primarily derived from interest, dividends from a fund generally will not qualify for the long-term capital gains tax rates available to individuals. 
If the Adviser buys shares on your behalf 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 taxable distribution.
Any taxable distributions you receive from a fund will normally be taxable to you when you receive them, regardless of your distribution option.
For each fund, 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. A capital gain or loss on your investment in a fund generally is the difference between the cost of your shares and the price you receive when you sell them.

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 fund pays a management fee to the Adviser.
The management fee is calculated and paid to the Adviser every month.
For Fidelity® SAI Low Duration Income Fund, the total management fee for the fiscal year ended August 31, 2023, was 0.25% of the fund's average net assets. On April 1, 2023, Fidelity® SAI Low Duration Income Fund's annual management fee rate has been reduced to 0.20% of its average net assets.
For Fidelity® SAI Short-Term Bond Fund, the total management fee for the fiscal year ended August 31, 2023, was 0.25% of the fund's average net assets. On April 1, 2023, the Adviser replaced Fidelity® SAI Short-Term Bond Fund's management fee, which consisted of a group fee rate component plus an individual fee rate, with a flat rate. Effective April 1, 2023, Fidelity® SAI Short-Term Bond Fund's annual management fee rate has been reduced to 0.20% of its average net assets.
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 each fund is available in each fund's semi-annual report for the fiscal period ended February 28, 2023 and in each fund's annual report for the fiscal period ended August 31, 2023.
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
 
FDC distributes each fund's shares.
Distribution and Service Plan(s)
Each 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 each 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 each fund has authorized such payments for shares of each fund.
Affiliates of the Adviser may receive service fees or distribution fees or both with respect to underlying funds that participate in Fidelity's FundsNetwork®.
If payments made by the Adviser to FDC or to intermediaries under a Distribution and Service Plan were considered to be paid out of a fund's assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.
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 funds or FDC. This prospectus and the related SAI do not constitute an offer by the funds or by FDC to sell shares of the funds to, or to buy shares of the funds from, any person to whom it is unlawful to make such offer.

IMPORTANT INFORMATION ABOUT OPENING A NEW ACCOUNT
To help the government fight the funding of terrorism and money laundering activities, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT ACT), requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account.
For individual investors opening an account: When you open an account, you will be asked for your name, address, date of birth, and other information that will allow Fidelity to identify you. You may also be asked to provide documents that may help to establish your identity, such as your driver's license.
For investors other than individuals: When you open an account, you will be asked for the name of the entity, its principal place of business and taxpayer identification number (TIN). You will be asked to provide information about the entity's control person and beneficial owners, and person(s) with authority over the account, including name, address, date of birth and social security number. You may also be asked to provide documents, such as drivers' licenses, articles of incorporation, trust instruments or partnership agreements and other information that will help Fidelity identify the entity.
You can obtain additional information about the funds. A description of each fund's policies and procedures for disclosing its holdings is available in its Statement of Additional Information (SAI) and on Fidelity's web sites. The SAI also includes more detailed information about each fund and its investments. The SAI is incorporated herein by reference (legally forms a part of the prospectus). Each fund's annual and semi-annual reports also include additional information. Each fund's annual report includes a discussion of the fund's holdings and recent market conditions and the fund's investment strategies that affected performance.
