Fund Summary

Fund:
Fidelity Flex® Mid Cap Index Fund

Investment Objective

The fund seeks to provide investment results that correspond to the total return of stocks of mid-capitalization United States companies.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund. In addition to the fees and expenses described below, your broker may also require you to pay brokerage commissions on purchases and sales 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   None
Distribution and/or Service (12b-1) fees   None
Other expenses   0.00%
Total annual operating expenses(a)   0.00%


(a)The 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.

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 your shareholder 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:

1 year $0
3 years $0
5 years $0
10 years $0


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 13% of the average value of its portfolio.

Principal Investment Strategies

  • Normally investing at least 80% of assets in securities included in the Russell Midcap® Index, which is a market capitalization-weighted index of medium-capitalization U.S. company stocks.
  • Lending securities to earn income for the fund.

Principal Investment Risks

  • Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.
  • 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. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction) can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's value or result in delays in recovering securities and/or capital from a counterparty.
  • Correlation to Index. The performance of the fund and its underlying index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, sample selection, regulatory restrictions, and timing differences associated with additions to and deletions from the index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on the fund and its shareholders.
  • Passive Management Risk. The fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the fund’s index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the fund’s performance could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers.
  • Mid Cap Investing. The value of securities of medium size, less well-known issuers can perform differently from the market as a whole and other types of stocks and can be more volatile than that of larger issuers.
  • Securities Lending Risk. Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral.

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.

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. The index description appears 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.

Fund Basics

Investment Details

Investment Objective

Fidelity Flex® Mid Cap Index Fund seeks to provide investment results that correspond to the total return of stocks of mid-capitalization United States companies.

Principal Investment Strategies

Geode normally invests at least 80% of the fund's assets in securities included in the Russell Midcap® Index. The Russell Midcap® Index is a market capitalization-weighted index of medium-capitalization U.S. company stocks.

The fund may not always hold all of the same securities as the Russell Midcap® Index. Geode may use statistical sampling techniques to attempt to replicate the returns of the Russell Midcap® Index. Statistical sampling techniques attempt to match the investment characteristics of the index and the fund by taking into account such factors as capitalization, industry exposures, dividend yield, price/earnings (P/E) ratio, price/book (P/B) ratio, and earnings growth.

The fund may not track the index because differences between the index and the fund's portfolio can cause differences in performance. In addition, expenses and transaction costs, the size and frequency of cash flows into and out of the fund, and differences between how and when the fund and the index are valued can cause differences in performance.

The fund may lend securities to broker-dealers or other institutions to earn income.

If Geode's strategies do not work as intended, the fund may not achieve its objective.

Description of Principal Security Types

Equity securities represent an ownership interest, or the right to acquire an ownership interest, in an issuer. Different types of equity securities provide different voting and dividend rights and priority in the event of the bankruptcy of the issuer. Equity securities include common stocks, preferred stocks, convertible securities, and warrants.

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 changes 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 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. 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:

Stock Market Volatility. The value of equity securities fluctuates in response to issuer, political, market, and economic developments. Fluctuations, especially in foreign markets, can be dramatic over the short as well as long term, and different parts of the market, including different market sectors, and different types of equity securities can react differently to these developments. For example, stocks of companies in one sector can react differently from those in another, large cap stocks can react differently from small cap stocks, and "growth" stocks can react differently from "value" stocks. Issuer, political, or economic developments can affect a single issuer, issuers within an industry or economic sector or geographic region, or the market as a whole. Changes in the financial condition of a single issuer can impact the market as a whole. Terrorism and related geo-political risks have led, and may in the future lead, to increased short-term market volatility and may have adverse long-term effects on world economies and markets generally.

Issuer-Specific Changes. Changes in the financial condition of an issuer or counterparty (e.g., broker-dealer or other borrower in a securities lending transaction), 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 value or result in delays in recovering securities and/or capital from a counterparty.

Correlation to Index. The performance of the fund and its index may vary somewhat due to factors such as fees and expenses of the fund, transaction costs, imperfect correlation between the fund's securities and those in its index, timing differences associated with additions to and deletions from its index, and changes in the shares outstanding of the component securities. In addition, the fund may not be able to invest in certain securities in its index or invest in them in the exact proportions in which they are represented in the index due to regulatory restrictions. The fund may not be fully invested at times, either as a result of cash flows into the fund or as a result of reserves of cash held by the fund to meet redemptions. The use of sampling techniques or futures or other derivative positions, as well as portfolio transactions carried out to minimize the distribution of capital gains to shareholders, may affect the fund's ability to achieve close correlation with its index. Errors in the construction or calculation of the index may occur from time to time and may not be identified and corrected for some period of time, which may have an adverse impact on the fund and its shareholders.

Passive Management Risk. An index fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the fund’s index or of the actual securities included in the index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, an index fund's performance could be lower than actively managed funds that may shift their portfolio assets to take advantage of market opportunities or lessen the impact of a market decline or a decline in the value of one or more issuers. The structure and composition of an index fund’s index will affect the performance, volatility, and risk of the index and, consequently, the performance, volatility, and risk of the fund.

Mid Cap Investing. The value of securities of medium size, less well-known issuers can be more volatile than that of relatively larger issuers and can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks.

Small Cap Investing. The value of securities of smaller, less well-known issuers can be more volatile than that of larger issuers and can react differently to issuer, political, market, and economic developments than the market as a whole and other types of stocks. Smaller issuers can have more limited product lines, markets, and financial resources.

Securities Lending Risk. Securities lending involves the risk that the borrower may fail to return the securities loaned in a timely manner or at all. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. These delays and costs could be greater for foreign securities. If a fund is not able to recover the securities loaned, the fund may sell the collateral and purchase a replacement investment in the market. The value of the collateral could decrease below the value of the replacement investment by the time the replacement investment is purchased.

Other Investment Strategies

In addition to the principal investment strategies discussed above, Geode may use various techniques, such as buying and selling futures contracts, swaps, and exchange traded funds, to increase or decrease a fund's exposure to changing security prices or other factors that affect security values. Geode may also engage in portfolio transactions carried out to minimize the distribution of capital gains to shareholders.

Shareholder Notice

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

Fidelity Flex® Mid Cap Index Fund normally invests at least 80% of its assets in securities included in the Russell Midcap® Index.

Fidelity Flex® Small Cap Index Fund normally invests at least 80% of its assets in securities included in the Russell 2000® Index.

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 as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. Each fund's assets normally are valued as of this time for the purpose of computing NAV.

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. 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.

Policies regarding excessive trading may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.

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

Frequent Purchases and Redemptions

A 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 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.

Each 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.

Excessive Trading Policy

The Board of Trustees has adopted policies designed to discourage excessive trading of fund shares. Excessive trading activity in a fund is measured by the number of roundtrip transactions in a shareholder's account and each class of a multiple class fund is treated separately. A roundtrip transaction occurs when a shareholder sells fund shares (including exchanges) within 30 days of the purchase date.

Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity® funds within any rolling 12-month period will be blocked for at least 85 days from additional purchases or exchange purchases across all Fidelity® funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block. Repeat offenders may be subject to long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's control at any time. In addition to enforcing these roundtrip limitations, the fund may in its discretion restrict, reject, or cancel any purchases or exchanges that, in the Adviser's opinion, may be disruptive to the management of the fund or otherwise not be in the fund's interests.

Exceptions

The following transactions are exempt from the fund's excessive trading policy described above: (i) systematic withdrawal and/or contribution programs, (ii) mandatory retirement distributions, (iii) transactions initiated by a plan sponsor or sponsors of certain employee benefit plans or other related accounts, (iv) transactions within a qualified advisory program, and (v) transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund of fund(s), or other strategy funds.

A qualified advisory program is one that demonstrates to Fidelity that the program has investment strategies and trading policies designed to protect the interests of long-term investors and meets specific criteria outlined by Fidelity.

A qualified fund of fund(s) is a mutual fund, qualified tuition program, or other strategy fund consisting of qualified plan assets that either applies the fund's excessive trading policies to shareholders at the fund of fund(s) level, or demonstrates that the fund of fund(s) has an investment strategy coupled with policies designed to control frequent trading that are reasonably likely to be effective as determined by the fund's Treasurer.

Fidelity may choose not to monitor transactions below certain dollar value thresholds.

Omnibus Accounts

Omnibus accounts, in which shares are held in the name of an intermediary on behalf of multiple investors, are a common form of holding shares among retirement plans and financial intermediaries such as brokers, advisers, and third-party administrators. Individual trades in omnibus accounts are often not disclosed to the fund, making it difficult to determine whether a particular shareholder is engaging in excessive trading. Excessive trading in omnibus accounts is likely to go undetected by the fund and may increase costs to the fund and disrupt its portfolio management.

Under policies adopted by the Board of Trustees, intermediaries will be permitted to apply the fund's excessive trading policy (described above), or their own excessive trading policy if approved by the Adviser. In these cases, the fund will typically not request or receive individual account data but will rely on the intermediary to monitor trading activity in good faith in accordance with its or the fund's policies. Reliance on intermediaries increases the risk that excessive trading may go undetected. For other intermediaries, the fund will generally monitor trading activity at the omnibus account level to attempt to identify disruptive trades. The fund may request transaction information, as frequently as daily, from any intermediary at any time, and may apply the fund's policy to transactions that exceed thresholds established by the Board of Trustees. The fund may prohibit purchases of fund shares by an intermediary or by some or all of any intermediary's clients. There is no assurance that the Adviser will request data with sufficient frequency to detect or deter excessive trading in omnibus accounts effectively.

If you purchase or sell fund shares through a financial intermediary, you may wish to contact the intermediary to determine the policies applicable to your account.

Retirement Plans

For employer-sponsored retirement plans, only participant directed exchanges count toward the roundtrip limits. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund.

Other Information about the Excessive Trading Policy

The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency. The fund reserves the right to modify its policies at any time without prior notice.

The fund does not knowingly accommodate frequent purchases and redemptions of fund shares by investors, except to the extent permitted by the policies described above.

As described in "Valuing Shares," the fund also uses fair value pricing to help reduce arbitrage opportunities available to short-term traders. There is no assurance that the fund's excessive trading policy will be effective, or will successfully detect or deter excessive or disruptive trading.

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.

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.

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.

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 a 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 each 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 funds may terminate or modify exchange privileges in the future.

Rollover IRAs (for Retirement Plans Only)

Shares of the funds 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 also 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, each 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 funds 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

Each fund earns dividends, interest, 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 pays dividends and capital gain distributions in June and December.

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. If you are not investing through a tax-advantaged retirement account, you should consider these tax consequences.

Taxes on Distributions

Distributions by each 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).

For accounts other than tax-advantaged retirement plan accounts, 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 of each fund's distributions, including dividends and distributions of short-term capital gains, are taxable to you as ordinary income, while certain of each fund's distributions, including distributions of long-term capital gains, are taxable to you generally as capital gains. A percentage of certain distributions of dividends may qualify for taxation at long-term capital gains rates (provided certain holding period requirements are met).

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 taxable distribution.

Any taxable distributions you receive from a fund will normally be taxable to you when you receive them.

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 a 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.

Fund Services

Fund Management

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

Adviser

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

As of December 31, 2021, the Adviser had approximately $3.6 trillion in discretionary assets under management, and approximately $4.5 trillion when combined with all of its affiliates' assets under management.

As the manager, the Adviser is responsible for handling each fund's business affairs.

Sub-Adviser(s)

Geode, at 100 Summer Street, 12th Floor, Boston, Massachusetts 02110, serves as a sub-adviser for each fund. Geode chooses each fund's investments and places orders to buy and sell each fund's investments.

As of December 31, 2021, Geode had approximately $945.4 billion in discretionary assets under management.

Portfolio Manager(s)

Louis Bottari is senior portfolio manager of each fund, which he has managed since March 2017. He also manages other funds. Since joining Geode in 2008, Mr. Bottari has worked as an assistant portfolio manager, portfolio manager, and senior portfolio manager.

Peter Matthew is senior portfolio manager of each fund, which he has managed since March 2017. He also manages other funds.

The statement of additional information (SAI) provides additional information about the compensation of, any other accounts managed by, and any fund shares held by the portfolio manager(s).

Advisory Fee(s)

Each fund does not pay a management fee to the Adviser. Each fund is available through certain fee-based accounts and advisory programs offered by the Adviser's affiliates. The Adviser is compensated for its services out of such fees.

The Adviser receives no fee from each fund for handling the business affairs of each fund and pays the expenses of each fund with limited exceptions.

The Adviser pays Geode for providing investment management services.

The basis for the Board of Trustees approving the management contract and sub-advisory agreement for each fund is available in each fund's semi-annual report for the fiscal period ended October 31, 2021.

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.

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)

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 not authorized such payments for shares of each fund.

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.

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.

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.
