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.

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 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.

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.

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. This compensation may take the form of payments for additional distribution-related activities and/or shareholder services and payments for educational seminars and training, including seminars sponsored by Fidelity, or by an intermediary. These payments are described in more detail in this section and in the SAI.

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.

The basis for the Board of Trustees approving the management contract and sub-advisory agreement for each fund will be included in each fund's annual report for the fiscal period ending October 31, 2018, when available.

The fund does not pay a management fee to the Adviser. The fund is available only to individual retail investors who purchase their shares through a Fidelity Brokerage account. Fidelity compensates the Adviser for the services it provides to the funds.

Robert Regan is co-manager of each fund, which he has managed since August 2018. He also manages other funds. Since joining Geode in 2016, Mr. Regan has worked as a portfolio manager. Prior to joining Geode, Mr. Regan was senior implementation portfolio manager at State Street Global Advisors from 2008 to 2016.

Louis Bottari is lead portfolio manager of each fund, which he has managed since August 2018. 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.

Your redemptions, including exchanges, 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. Fund Services Fund Management

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

If you 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.

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).

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.

If your dividend check(s) remains uncashed for six months, your check(s) may be invested in additional shares at the NAV next calculated on the day of the investment.

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

Not all distribution options may be available for every account and certain restrictions may apply. If the distribution option you prefer is not listed on your account application, or if you want to change your current distribution option, visit Fidelity's web site at www.fidelity.com or call 1-800-544-6666 for more information.

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

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

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

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.

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.

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.

Current regulations allow Fidelity to send a single copy of shareholder documents for Fidelity ® funds, such as prospectuses, annual and semiannual reports, and proxy materials, to certain mutual fund customers whom we believe are members of the same family who share the same address. For certain types of accounts, we will not send multiple copies of these documents to you and members of your family who share the same address. Instead, we will send only a single copy of these documents. This will continue for as long as you are a shareholder, unless you notify us otherwise. If at any time you choose to receive individual copies of any documents, please call 1-800-544-8544. We will begin sending individual copies to you within 30 days of receiving your call.

The following features may be available to buy and sell shares of a fund or to move money to and from your account. Please visit Fidelity's web site at www.fidelity.com or call 1-800-544-6666 for more information.

Other funds may have different exchange restrictions and minimums, and may impose redemption fees of up to 2.00% of the amount exchanged. Check each fund's prospectus for details.

An exchange involves the redemption of all or a portion of the shares of one fund and the purchase of shares of another fund.

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.

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.

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.

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.

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.

A signature guarantee is designed to protect you and Fidelity from fraud. If you hold your shares in a Fidelity ® mutual fund account and submit your request to Fidelity by mail, Fidelity may require that your request be made in writing and include a signature guarantee in certain circumstances, such as:

Each fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves 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.

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.

Certain financial institutions that have entered into sales agreements with Fidelity Distributors Corporation (FDC) may enter confirmed purchase orders on behalf of customers by phone, with payment to follow no later than the time when fund shares are priced on the following business day. If payment is not received by that time, the order will be canceled and the financial institution could be held liable for resulting fees or losses.

If your payment is not received and collected, your purchase may be canceled and you could be liable for any losses or fees a fund or Fidelity has incurred.

Each fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the NAV next calculated after the order is received by the authorized intermediary. If applicable, orders by funds of funds for which Fidelity serves 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.

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.

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.

A qualified wrap program is: (i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, (ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and (iii) managed by an adviser who agrees to give the Adviser sufficient information to permit the Adviser to identify the individual accounts in the wrap program.

The fund will monitor aggregate trading activity of adviser transactions to attempt to identify excessive trading in qualified wrap programs, as defined below. Excessive trading by an adviser will lead to fund blocks and the wrap program will lose its qualified status. Transactions of an adviser will not be matched with client-directed transactions unless the wrap program ceases to be a qualified wrap program (but all client-directed transactions will be subject to the fund's excessive trading policy).

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.

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.

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.

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.

The following transactions are exempt from the fund's excessive trading policy described above: (i) transactions of $1,000 or less, (ii) systematic withdrawal and/or contribution programs, (iii) mandatory retirement distributions, and (iv) transactions initiated by a plan sponsor or sponsors of certain employee benefit plans or other related accounts. In addition, the fund's excessive trading policy does not apply to 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 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.

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.

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.

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 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.

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.

You may also buy or sell shares through a retirement account (such as an IRA or an account funded through salary deduction). Retirement specialists are available at 1-800-544-4774 to answer your questions about Fidelity ® retirement products. If you buy or sell shares through a retirement account the procedures for buying, selling, and exchanging shares and the account features, policies, and fees may differ from those discussed in this prospectus. Fees in addition to those discussed in this prospectus may apply.

If you do not currently have a Fidelity ® brokerage account and would like to invest in a fund, you may need to complete an application. For more information about a Fidelity ® brokerage account, please visit Fidelity's web site at www.fidelity.com, call 1-800-FIDELITY, or visit a Fidelity Investor Center (call 1-800-544-9797 for the center nearest you).

Subject to the purchase and sale requirements stated in this prospectus, you may buy or sell shares through a Fidelity ® brokerage account. If you buy or sell shares (other than by exchange) through a Fidelity ® brokerage account, your transactions generally involve your Fidelity ® brokerage core (a settlement vehicle included as part of your Fidelity ® brokerage account).

In addition to its mutual fund business, the company operates one of America's leading brokerage firms, Fidelity Brokerage Services LLC. Fidelity is also a leader in providing tax-advantaged retirement plans for individuals investing on their own or through their employer.

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.

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 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.

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.

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 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).

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.

Fidelity ZERO℠ International Index Fund normally invests at least 80% of the fund's assets in common stock included in the Fidelity Global ex U.S. Index℠ and in depository receipts representing securities included in the index.

The Fidelity U.S. Total Investable Market Index℠ is a float-adjusted market capitalization-weighted index designed to reflect the performance of the U.S. equity market, including large-, mid- and small-capitalization stocks. The index was created by FMRC using a rules-based proprietary index methodology that includes all U.S. stocks meeting certain market capitalization, liquidity and investability requirements (i.e., a float-adjusted market capitalization greater than $75 million, the ratio of free float shares to total outstanding shares must be greater than 15%, and minimum six-month volume traded of $25 million). The index, which is limited to the top 3,000 companies, included approximately 2,500 constituents as of April 30, 2018. The index is rebalanced annually, with a provision to make adjustments for certain corporate actions on a quarterly basis.

The Fidelity Global ex U.S. Index℠ is a float-adjusted market capitalization-weighted index designed to reflect the performance of non-U.S. large- and mid-cap stocks. The index was created by FMRC using a rules-based proprietary index methodology that includes all non-U.S. developed and emerging market stocks meeting certain market capitalization, liquidity and investability requirements (i.e., a float-adjusted market capitalization on a country by country basis with the top 98% of each countrys total market cap included, a float-adjusted market capitalization greater than $100 million, the ratio of free float shares to total outstanding shares must be greater than 15%, and minimum six-month volume traded of $25 million). The index, which is limited to the top 90% of stocks by market cap within each country, included approximately 2,300 constituents as of April 30, 2018. The index is rebalanced annually, with a provision to make adjustments for certain corporate actions on a quarterly basis.

In addition to the principal investment strategies discussed above, Geode may also use various techniques, such as buying and selling futures contracts, swaps,and exchange traded funds, to increase or decrease the funds exposure to changing security prices or other factors that affect security values.

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.

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.

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 may affect the fund's ability to achieve close correlation with its index.

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. The value of securities of smaller, less well-known issuers can be more volatile than that of larger issuers.

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.

Investing in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets. The extent of economic development; political stability; market depth, infrastructure, and capitalization; and regulatory oversight can be less than in more developed markets. Emerging market economies can be subject to greater social, economic, regulatory, and political uncertainties. All of these factors can make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.

Foreign and Emerging Market Risk . Foreign securities, foreign currencies, 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, especially those in emerging markets, more volatile and potentially less liquid than U.S. investments. In addition, foreign markets can perform differently from the U.S. market.

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.

Many factors affect each 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.

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.

The fund will invest more than 25% of its total assets in securities of issuers in a particular industry or group of industries to approximately the same extent that the funds index concentrates in the securities of issuers in a particular industry or group of industries.

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 not always hold all of the same securities as the Fidelity U.S. Total Investable Market Index℠. Geode may use statistical sampling techniques to attempt to replicate the returns of the Fidelity U.S. Total Investable Market Index℠ using a smaller number of securities. 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, P/E ratio, P/B ratio, and earnings growth.

Geode normally invests at least 80% of the fund's assets in common stocks included in the Fidelity U.S. Total Investable Market Index℠. The Fidelity U.S. Total Investable Market Index℠ is a float-adjusted market capitalization-weighted index designed to reflect the performance of the U.S. equity market, including large-, mid- and small-capitalization stocks.

TABLE OF CONTENTS

INVESTMENT POLICIES AND LIMITATIONS

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

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

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

Diversification

For each fund:

The fund may not with respect to 75% of the fund's total assets, purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities, or securities of other investment companies) if, as a result, (a) more than 5% of the fund's total assets would be invested in the securities of that issuer, or (b) the fund would hold more than 10% of the outstanding voting securities of that issuer.

Senior Securities

For each fund:

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

Borrowing

For each fund:

The fund may not borrow money, except that the fund may borrow money for temporary or emergency purposes (not for leveraging or investment) in an amount not exceeding 33 1/3% of its total assets (including the amount borrowed) less liabilities (other than borrowings). Any borrowings that come to exceed this amount will be reduced within three days (not including Sundays and holidays) to the extent necessary to comply with the 33 1/3% limitation.

Underwriting

For each fund:

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

Concentration

For each fund:

The fund will invest more than 25% of its total assets in securities of issuers in a particular industry or group of industries to approximately the same extent that the funds index concentrates in the securities of issuers in a particular industry or group of industries.

For purposes of each of Fidelity ZERO℠ International Index Funds and Fidelity ZERO℠ Total Market Index Funds concentration limitation discussed above, securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities are not considered to be issued by members of any industry.

For purposes of each of Fidelity ZERO℠ International Index Funds and Fidelity ZERO℠ Total Market Index Funds concentration limitation discussed above, with respect to any investment in repurchase agreements collateralized by U.S. Government securities, FMR Co., Inc. (FMRC) looks through to the U.S. Government securities.

For purposes of each of Fidelity ZERO℠ International Index Fund's and Fidelity ZERO℠ Total Market Index Fund's concentration limitation discussed above, with respect to any investment in Fidelity® Money Market Central Fund and/or any non-money market central fund, FMRC looks through to the holdings of the central fund.

Real Estate

For each fund:

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

Commodities

For each fund:

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

Loans

For each fund:

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

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

Short Sales

For each fund:

The fund does not currently intend to sell securities short, unless it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts and options are not deemed to constitute selling securities short.

Margin Purchases

For each fund:

The fund does not currently intend to purchase securities on margin, except that the fund may obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments in connection with futures contracts and options on futures contracts shall not constitute purchasing securities on margin.

Borrowing

For each fund:

The fund may borrow money only (a) from a bank or from a registered investment company or portfolio for which FMRC or an affiliate serves as investment adviser or (b) by engaging in reverse repurchase agreements with any party (reverse repurchase agreements are treated as borrowings for purposes of the fundamental borrowing investment limitation).

Illiquid Securities

For each fund:

The fund does not currently intend to purchase any security if, as a result, more than 10% of its net assets would be invested in securities that are deemed to be illiquid because they are subject to legal or contractual restrictions on resale or because they cannot be sold or disposed of in the ordinary course of business at approximately the prices at which they are valued.

For purposes of each fund's illiquid securities limitation discussed above, if through a change in values, net assets, or other circumstances, the fund were in a position where more than 10% of its net assets were invested in illiquid securities, it would consider appropriate steps to protect liquidity.

Loans

For each fund:

The fund does not currently intend to lend assets other than securities to other parties, except by (a) lending money (up to 15% of the fund's net assets) to a registered investment company or portfolio for which FMRC or an affiliate serves as investment adviser or (b) assuming any unfunded commitments in connection with the acquisition of loans, loan participations, or other forms of debt instruments. (This limitation does not apply to purchases of debt securities, to repurchase agreements, or to acquisitions of loans, loan participations or other forms of debt instruments.)

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

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

For a fund's policies and limitations on futures, options, and swap transactions, as applicable, see "Investment Policies and Limitations - Futures, Options, and Swaps."

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

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

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

Borrowing. If a fund borrows money, its share price may be subject to greater fluctuation until the borrowing is paid off. If a fund makes additional investments while borrowings are outstanding, this may be considered a form of leverage.

Cash Management. A fund may hold uninvested cash or may invest it in cash equivalents such as money market securities, repurchase agreements, or shares of short-term bond or money market funds, including (for Fidelity® funds and other advisory clients only) shares of Fidelity® central funds. Generally, these securities offer less potential for gains than other types of securities.

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

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

Common Stock represents an equity or ownership interest in an issuer. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock, although related proceedings can take time to resolve and results can be unpredictable. For purposes of a Fidelity® fund's policies related to investment in common stock Fidelity considers depositary receipts evidencing ownership of common stock to be common stock.

Convertible Securities are bonds, debentures, notes, or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by a fund is called for redemption or conversion, the fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at prices above their "conversion value," which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates. When the underlying common stocks decline in value, convertible securities will tend not to decline to the same extent because of the interest or dividend payments and the repayment of principal at maturity for certain types of convertible securities. However, securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder. When the underlying common stocks rise in value, the value of convertible securities may also be expected to increase. At the same time, however, the difference between the market value of convertible securities and their conversion value will narrow, which means that the value of convertible securities will generally not increase to the same extent as the value of the underlying common stocks. Because convertible securities may also be interest-rate sensitive, their value may increase as interest rates fall and decrease as interest rates rise. Convertible securities are also subject to credit risk, and are often lower-quality securities.

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 interest but are sold at a deep discount from their face values. Debt securities include corporate bonds, government securities, repurchase agreements, and mortgage and other asset-backed securities.

Exchange Traded Funds (ETFs) are shares of other investment companies, commodity pools, or other entities that are traded on an exchange. Typically, assets underlying the ETF shares are stocks, though they may also be commodities or other instruments. An ETF may seek to replicate the performance of a specific index or may be actively managed.

Typically, shares of an ETF that tracks an index are expected to increase in value as the value of the underlying benchmark increases. However, in the case of inverse ETFs (also called "short ETFs" or "bear ETFs"), ETF shares are expected to increase in value as the value of the underlying benchmark decreases. Inverse ETFs seek to deliver the opposite of the performance of the benchmark they track and are often marketed as a way for investors to profit from, or at least hedge their exposure to, downward moving markets. Investments in inverse ETFs are similar to holding short positions in the underlying benchmark.

ETF shares are redeemable only in large blocks (typically, 50,000 shares) often called "creation units" by persons other than a fund, and are redeemed principally in-kind at each day's next calculated net asset value per share (NAV). ETFs typically incur fees that are separate from those fees incurred directly by a fund. A fund's purchase of ETFs results in the layering of expenses, such that the fund would indirectly bear a proportionate share of any ETF's operating expenses. Further, while traditional investment companies are continuously offered at NAV, ETFs are traded in the secondary market (e.g., on a stock exchange) on an intra-day basis at prices that may be above or below the value of their underlying portfolios.

Some of the risks of investing in an ETF that tracks an index are similar to those of investing in an indexed mutual fund, including tracking error risk (the risk of errors in matching the ETF's underlying assets to the index or other benchmark); and the risk that because an ETF that tracks an index is not actively managed, it cannot sell stocks or other assets as long as they are represented in the index or other benchmark. Other ETF risks include the risk that ETFs may trade in the secondary market at a discount from their NAV and the risk that the ETFs may not be liquid. ETFs also may be leveraged. Leveraged ETFs seek to deliver multiples of the performance of the index or other benchmark they track and use derivatives in an effort to amplify the returns (or decline, in the case of inverse ETFs) of the underlying index or benchmark. While leveraged ETFs may offer the potential for greater return, the potential for loss and the speed at which losses can be realized also are greater. Most leveraged and inverse ETFs "reset" daily, meaning they are designed to achieve their stated objectives on a daily basis. Leveraged and inverse ETFs can deviate substantially from the performance of their underlying benchmark over longer periods of time, particularly in volatile periods.

Exchange Traded Notes (ETNs) are a type of senior, unsecured, unsubordinated debt security issued by financial institutions that combines aspects of both bonds and ETFs. An ETN's returns are based on the performance of a market index or other reference asset minus fees and expenses. Similar to ETFs, ETNs are listed on an exchange and traded in the secondary market. However, unlike an ETF, an ETN can be held until the ETN's maturity, at which time the issuer will pay a return linked to the performance of the market index or other reference asset to which the ETN is linked minus certain fees. Unlike regular bonds, ETNs typically do not make periodic interest payments and principal typically is not protected.

ETNs also incur certain expenses not incurred by their applicable index. The market value of an ETN is determined by supply and demand, the current performance of the index or other reference asset, and the credit rating of the ETN issuer. The market value of ETN shares may differ from their intraday indicative value. The value of an ETN may also change due to a change in the issuer's credit rating. As a result, there may be times when an ETN's share trades at a premium or discount to its NAV. Some ETNs that use leverage in an effort to amplify the returns of an underlying index or other reference asset can, at times, be relatively illiquid and, thus, they may be difficult to purchase or sell at a fair price. Leveraged ETNs may offer the potential for greater return, but the potential for loss and speed at which losses can be realized also are greater.

Exposure to Foreign and Emerging Markets. Foreign securities, foreign currencies, and securities issued by U.S. entities with substantial foreign operations may involve significant risks in addition to the risks inherent in U.S. investments.

Foreign investments involve risks relating to local political, economic, regulatory, or social instability, military action or unrest, or adverse diplomatic developments, and may be affected by actions of foreign governments adverse to the interests of U.S. investors. Such actions may include expropriation or nationalization of assets, confiscatory taxation, restrictions on U.S. investment or on the ability to repatriate assets or convert currency into U.S. dollars, or other government intervention. From time to time, a fund's adviser and/or its affiliates may determine that, as a result of regulatory requirements that may apply to the adviser and/or its affiliates due to investments in a particular country, investments in the securities of issuers domiciled or listed on trading markets in that country above certain thresholds (which may apply at the account level or in the aggregate across all accounts managed by the adviser and its affiliates) may be impractical or undesirable. In such instances, the adviser may limit or exclude investment in a particular issuer, and investment flexibility may be restricted. There is no assurance that a fund's adviser will be able to anticipate these potential events or counter their effects. In addition, the value of securities denominated in foreign currencies and of dividends and interest paid with respect to such securities will fluctuate based on the relative strength of the U.S. dollar.

It is anticipated that in most cases the best available market for foreign securities will be on an exchange or in over-the-counter (OTC) markets located outside of the United States. Foreign stock markets, while growing in volume and sophistication, are generally not as developed as those in the United States, and securities of some foreign issuers may be less liquid and more volatile than securities of comparable U.S. issuers. Foreign security trading, settlement and custodial practices (including those involving securities settlement where fund assets may be released prior to receipt of payment) are often less developed than those in U.S. markets, and may result in increased investment or valuation risk or substantial delays in the event of a failed trade or the insolvency of, or breach of duty by, a foreign broker-dealer, securities depository, or foreign subcustodian. In addition, the costs associated with foreign investments, including withholding taxes, brokerage commissions, and custodial costs, are generally higher than with U.S. investments.

Foreign markets may offer less protection to investors than U.S. markets. Foreign issuers are generally not bound by uniform accounting, auditing, and financial reporting requirements and standards of practice comparable to those applicable to U.S. issuers. Adequate public information on foreign issuers may not be available, and it may be difficult to secure dividends and information regarding corporate actions on a timely basis. In general, there is less overall governmental supervision and regulation of securities exchanges, brokers, and listed companies than in the United States. OTC markets tend to be less regulated than stock exchange markets and, in certain countries, may be totally unregulated. Regulatory enforcement may be influenced by economic or political concerns, and investors may have difficulty enforcing their legal rights in foreign countries.

Some foreign securities impose restrictions on transfer within the United States or to U.S. persons. Although securities subject to such transfer restrictions may be marketable abroad, they may be less liquid than foreign securities of the same class that are not subject to such restrictions.

American Depositary Receipts (ADRs) as well as other "hybrid" forms of ADRs, including European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs), are certificates evidencing ownership of shares of a foreign issuer. These certificates are issued by depository banks and generally trade on an established market in the United States or elsewhere. The underlying shares are held in trust by a custodian bank or similar financial institution in the issuer's home country. The depository bank may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding dividends and interest and corporate actions. ADRs are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. However, ADRs continue to be subject to many of the risks associated with investing directly in foreign securities. These risks include foreign exchange risk as well as the political and economic risks of the underlying issuer's country.

The risks of foreign investing may be magnified for investments in emerging markets. Security prices in emerging markets can be significantly more volatile than those in more developed markets, reflecting the greater uncertainties of investing in less established markets and economies. In particular, countries with emerging markets may have relatively unstable governments, may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and may have less protection of property rights than more developed countries. The economies of countries with emerging markets may be based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. Local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times.

Foreign Currency Transactions. A fund may conduct foreign currency transactions on a spot (i.e., cash) or forward basis (i.e., by entering into forward contracts to purchase or sell foreign currencies). Although foreign exchange dealers generally do not charge a fee for such conversions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency at one rate, while offering a lesser rate of exchange should the counterparty desire to resell that currency to the dealer. Forward contracts are customized transactions that require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future. Forward contracts are generally traded in an interbank market directly between currency traders (usually large commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange.

The following discussion summarizes the principal currency management strategies involving forward contracts that could be used by a fund. A fund may also use swap agreements, indexed securities, and options and futures contracts relating to foreign currencies for the same purposes. Forward contracts not calling for physical delivery of the underlying instrument will be settled through payments in U.S. dollars rather than through delivery of the underlying currency. All of these instruments and transactions are subject to the risk that the counterparty will default.

A "settlement hedge" or "transaction hedge" is designed to protect a fund against an adverse change in foreign currency values between the date a security denominated in a foreign currency is purchased or sold and the date on which payment is made or received. Entering into a forward contract for the purchase or sale of the amount of foreign currency involved in an underlying security transaction for a fixed amount of U.S. dollars "locks in" the U.S. dollar price of the security. Forward contracts to purchase or sell a foreign currency may also be used to protect a fund in anticipation of future purchases or sales of securities denominated in foreign currency, even if the specific investments have not yet been selected.

A fund may also use forward contracts to hedge against a decline in the value of existing investments denominated in a foreign currency. For example, if a fund owned securities denominated in pounds sterling, it could enter into a forward contract to sell pounds sterling in return for U.S. dollars to hedge against possible declines in the pound's value. Such a hedge, sometimes referred to as a "position hedge," would tend to offset both positive and negative currency fluctuations, but would not offset changes in security values caused by other factors. A fund could also attempt to hedge the position by selling another currency expected to perform similarly to the pound sterling. This type of hedge, sometimes referred to as a "proxy hedge," could offer advantages in terms of cost, yield, or efficiency, but generally would not hedge currency exposure as effectively as a direct hedge into U.S. dollars. Proxy hedges may result in losses if the currency used to hedge does not perform similarly to the currency in which the hedged securities are denominated.

A fund may enter into forward contracts to shift its investment exposure from one currency into another. This may include shifting exposure from U.S. dollars to a foreign currency, or from one foreign currency to another foreign currency. This type of strategy, sometimes known as a "cross-hedge," will tend to reduce or eliminate exposure to the currency that is sold, and increase exposure to the currency that is purchased, much as if a fund had sold a security denominated in one currency and purchased an equivalent security denominated in another. A fund may cross-hedge its U.S. dollar exposure in order to achieve a representative weighted mix of the major currencies in its benchmark index and/or to cover an underweight country or region exposure in its portfolio. Cross-hedges protect against losses resulting from a decline in the hedged currency, but will cause a fund to assume the risk of fluctuations in the value of the currency it purchases.

Successful use of currency management strategies will depend on an adviser's skill in analyzing currency values. Currency management strategies may substantially change a fund's investment exposure to changes in currency exchange rates and could result in losses to a fund if currencies do not perform as an adviser anticipates. For example, if a currency's value rose at a time when a fund had hedged its position by selling that currency in exchange for dollars, the fund would not participate in the currency's appreciation. If a fund hedges currency exposure through proxy hedges, the fund could realize currency losses from both the hedge and the security position if the two currencies do not move in tandem. Similarly, if a fund increases its exposure to a foreign currency and that currency's value declines, the fund will realize a loss. Foreign currency transactions involve the risk that anticipated currency movements will not be accurately predicted and that a fund's hedging strategies will be ineffective. Moreover, it is impossible to precisely forecast the market value of portfolio securities at the expiration of a foreign currency forward contract. Accordingly, a fund may be required to buy or sell additional currency on the spot market (and bear the expenses of such transaction), if an adviser's predictions regarding the movement of foreign currency or securities markets prove inaccurate.

A fund may be required to limit its hedging transactions in foreign currency forwards, futures, and options in order to maintain its classification as a "regulated investment company" under the Internal Revenue Code (Code). Hedging transactions could result in the application of the mark-to-market provisions of the Code, which may cause an increase (or decrease) in the amount of taxable dividends paid by a fund and could affect whether dividends paid by a fund are classified as capital gains or ordinary income. A fund will cover its exposure to foreign currency transactions with liquid assets in compliance with applicable requirements. There is no assurance that an adviser's use of currency management strategies will be advantageous to a fund or that it will employ currency management strategies at appropriate times.

Options and Futures Relating to Foreign Currencies. Currency futures contracts are similar to forward currency exchange contracts, except that they are traded on exchanges (and have margin requirements) and are standardized as to contract size and delivery date. Most currency futures contracts call for payment or delivery in U.S. dollars. The underlying instrument of a currency option may be a foreign currency, which generally is purchased or delivered in exchange for U.S. dollars, or may be a futures contract. The purchaser of a currency call obtains the right to purchase the underlying currency, and the purchaser of a currency put obtains the right to sell the underlying currency.

The uses and risks of currency options and futures are similar to options and futures relating to securities or indexes, as discussed below. A fund may purchase and sell currency futures and may purchase and write currency options to increase or decrease its exposure to different foreign currencies. Currency options may also be purchased or written in conjunction with each other or with currency futures or forward contracts. Currency futures and options values can be expected to correlate with exchange rates, but may not reflect other factors that affect the value of a fund's investments. A currency hedge, for example, should protect a Yen-denominated security from a decline in the Yen, but will not protect a fund against a price decline resulting from deterioration in the issuer's creditworthiness. Because the value of a fund's foreign-denominated investments changes in response to many factors other than exchange rates, it may not be possible to match the amount of currency options and futures to the value of the fund's investments exactly over time.

Currency options traded on U.S. or other exchanges may be subject to position limits which may limit the ability of the fund to reduce foreign currency risk using such options.

Foreign Repurchase Agreements. Foreign repurchase agreements involve an agreement to purchase a foreign security and to sell that security back to the original seller at an agreed-upon price in either U.S. dollars or foreign currency. Unlike typical U.S. repurchase agreements, foreign repurchase agreements may not be fully collateralized at all times. The value of a security purchased by a fund may be more or less than the price at which the counterparty has agreed to repurchase the security. In the event of default by the counterparty, a fund may suffer a loss if the value of the security purchased is less than the agreed-upon repurchase price, or if the fund is unable to successfully assert a claim to the collateral under foreign laws. As a result, foreign repurchase agreements may involve higher credit risks than repurchase agreements in U.S. markets, as well as risks associated with currency fluctuations. In addition, as with other emerging market investments, repurchase agreements with counterparties located in emerging markets or relating to emerging markets may involve issuers or counterparties with lower credit ratings than typical U.S. repurchase agreements.

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

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

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

Funds' Rights as Investors. Fidelity® funds do not intend to direct or administer the day-to-day operations of any company. A fund may, however, exercise its rights as a shareholder or lender and may communicate its views on important matters of policy to a company's management, board of directors, and shareholders, and holders of a company's other securities when such matters could have a significant effect on the value of the fund's investment in the company. The activities in which a fund may engage, either individually or in conjunction with others, may include, among others, supporting or opposing proposed changes in a company's corporate structure or business activities; seeking changes in a company's directors or management; seeking changes in a company's direction or policies; seeking the sale or reorganization of the company or a portion of its assets; supporting or opposing third-party takeover efforts; supporting the filing of a bankruptcy petition; or foreclosing on collateral securing a security. This area of corporate activity is increasingly prone to litigation and it is possible that a fund could be involved in lawsuits related to such activities. Such activities will be monitored with a view to mitigating, to the extent possible, the risk of litigation against a fund and the risk of actual liability if a fund is involved in litigation. No guarantee can be made, however, that litigation against a fund will not be undertaken or liabilities incurred. A fund's proxy voting guidelines are included in its SAI.

Futures, Options, and Swaps. The success of any strategy involving futures, options, and swaps depends on an adviser's analysis of many economic and mathematical factors and a fund's return may be higher if it never invested in such instruments. Additionally, some of the contracts discussed below are new instruments without a trading history and there can be no assurance that a market for the instruments will continue to exist. Government legislation or regulation could affect the use of such instruments and could limit a fund's ability to pursue its investment strategies. If a 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.

Each fund will not: (a) sell futures contracts, purchase put options, or write call options if, as a result, more than 25% of the fund's total assets would be hedged with futures and options under normal conditions; (b) purchase futures contracts or write put options if, as a result, the fund's total obligations upon settlement or exercise of purchased futures contracts and written put options would exceed 25% of its total assets under normal conditions; or (c) purchase call options if, as a result, the current value of option premiums for call options purchased by the fund would exceed 5% of the fund's total assets. These limitations do not apply to options attached to or acquired or traded together with their underlying securities, and do not apply to structured notes.

The policies and limitations regarding the funds' investments in futures contracts, options, and swaps may be changed as regulatory agencies permit.

The requirements for qualification as a regulated investment company may limit the extent to which a fund may enter into futures, options on futures, and forward contracts.

Futures Contracts. In purchasing a futures contract, the buyer agrees to purchase a specified underlying instrument at a specified future date. In selling a futures contract, the seller agrees to sell a specified underlying instrument at a specified date. Futures contracts are standardized, exchange-traded contracts and the price at which the purchase and sale will take place is fixed when the buyer and seller enter into the contract. Some currently available futures contracts are based on specific securities or baskets of securities, some are based on commodities or commodities indexes (for funds that seek commodities exposure), and some are based on indexes of securities prices (including foreign indexes for funds that seek foreign exposure). Futures on indexes and futures not calling for physical delivery of the underlying instrument will be settled through cash payments rather than through delivery of the underlying instrument. Futures can be held until their delivery dates, or can be closed out by offsetting purchases or sales of futures contracts before then if a liquid market is available. A fund may realize a gain or loss by closing out its futures contracts.

The value of a futures contract tends to increase and decrease in tandem with the value of its underlying instrument. Therefore, purchasing futures contracts will tend to increase a fund's exposure to positive and negative price fluctuations in the underlying instrument, much as if it had purchased the underlying instrument directly. When a fund sells a futures contract, by contrast, the value of its futures position will tend to move in a direction contrary to the market for the underlying instrument. Selling futures contracts, therefore, will tend to offset both positive and negative market price changes, much as if the underlying instrument had been sold.

The purchaser or seller of a futures contract or an option for a futures contract is not required to deliver or pay for the underlying instrument or the final cash settlement price, as applicable, unless the contract is held until the delivery date. However, both the purchaser and seller are required to deposit "initial margin" with a futures broker, known as a futures commission merchant (FCM), when the contract is entered into. If the value of either party's position declines, that party will be required to make additional "variation margin" payments to settle the change in value on a daily basis. This process of "marking to market" will be reflected in the daily calculation of open positions computed in a fund's NAV. The party that has a gain is entitled to receive all or a portion of this amount. Initial and variation marg
