Investment Objective

The fund seeks a combination of a high level of income and the potential for capital gains.

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 certain share classes of the fund.

You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the fund or certain other Fidelity ® funds. More information about these and other discounts is available from your investment professional and in the "Fund Distribution" section beginning on page 29 of the prospectus. Different intermediaries may provide additional waivers or reductions of the sales charge. Please see “Sales Charge Waiver Policies Applied by Certain Intermediaries” in the “Appendix” section of the prospectus.

Shareholder fees

(a)   Based on estimated amounts for the current fiscal year.

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. 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 and if you hold your shares:

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 45% of the average value of its portfolio.

Principal Investment Strategies

Principal Investment Risks

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.

Visit institutional.fidelity.com for more recent performance information.

Performance history will be available for Class Z after Class Z has been in operation for one calendar year.

Year-by-Year Returns

The returns in the bar chart do not reflect any applicable sales charges; if sales charges were reflected, returns would be lower than those shown.

Tax Information

Distributions you receive from the fund are subject to federal income tax and generally will be taxed as ordinary income or capital gains, and may also be subject to state or local taxes, unless you are investing through a tax-advantaged retirement account (in which case you may be taxed later, upon withdrawal of your investment from such account).

Payments to Broker-Dealers and Other Financial Intermediaries

The fund, the Adviser, Fidelity Distributors Corporation (FDC), and/or their affiliates may pay intermediaries, which may include banks, broker-dealers, retirement plan sponsors, administrators, or service-providers (who may be affiliated with the Adviser or FDC), for the sale of fund shares and related services. These payments may create a conflict of interest by influencing your intermediary and your investment professional to recommend the fund over another investment. Ask your investment professional or visit your intermediary's web site for more information.

Fund Basics

Investment Details

Investment Objective

Fidelity Advisor ® High Income Advantage Fund seeks a combination of a high level of income and the potential for capital gains.

Principal Investment Strategies

The Adviser normally invests the fund's assets primarily in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds). Many lower-quality debt securities are subject to legal or contractual restrictions limiting the Adviser's ability to resell the securities to the general public. The Adviser may also invest the fund's assets in non-income producing securities, including defaulted securities and common stocks. The Adviser currently intends to limit common stocks to 20% of the fund's total assets. The Adviser may invest in companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings.

The Adviser may invest the fund's assets in securities of foreign issuers in addition to securities of domestic issuers.

In buying and selling securities for the fund, the Adviser relies on fundamental analysis of each issuer and its potential for success in light of its current financial condition, its industry position, and economic and market conditions. Factors considered include a security's structural features and current price compared to its long-term value, and the earnings potential, credit standing, and management of the security's issuer.

If the Adviser'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.

Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Some debt securities, such as zero coupon bonds, do not pay current interest but are sold at a discount from their face values. Debt securities include corporate bonds, government securities (including Treasury securities), repurchase agreements, money market securities, mortgage and other asset-backed securities, loans and loan participations, and other securities believed to have debt-like characteristics, including hybrids and synthetic securities.

Principal Investment Risks

Many factors affect the fund's performance. The fund's share price and yield change daily based on changes in market conditions and interest rates and in response to other economic, political, or financial developments. The fund's reaction to these developments will be affected by the types and maturities of securities in which the fund invests, the financial condition, industry and economic sector, and geographic location of an issuer, and the fund's level of investment in the securities of that issuer. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.

The following factors can significantly affect the fund's performance:

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.

Interest Rate Changes. Debt securities, including money market securities, have varying levels of sensitivity to changes in interest rates. In general, the price of a debt security can fall when interest rates rise and can rise when interest rates fall. Securities with longer maturities and certain types of securities, such as mortgage securities and the securities of issuers in the financial services sector, can be more sensitive to interest rate changes, meaning the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. Short-term and long-term interest rates do not necessarily move in the same amount or the same direction. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Securities with floating interest rates can be less sensitive to interest rate changes, but may decline in value if their interest rates do not rise as much as interest rates in general. Securities whose payment at maturity is based on the movement of all or part of an index and inflation-protected debt securities may react differently from other types of debt securities.

Foreign Exposure . 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.

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.

Issuer-Specific Changes . Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value. The value of securities of smaller, less well-known issuers can be more volatile than that of larger issuers. Lower-quality debt securities (those of less than investment-grade quality, also referred to as high yield debt securities or junk bonds) and certain types of other securities tend to be particularly sensitive to these changes.

Lower-quality debt securities and certain types of other securities involve greater risk of default or price changes due to changes in the credit quality of the issuer. The value of lower-quality debt securities and certain types of other securities often fluctuates in response to company, political, or economic developments and can decline significantly over short as well as long periods of time or during periods of general or regional economic difficulty. Lower-quality debt securities can be thinly traded or have restrictions on resale, making them difficult to sell at an acceptable price, and often are considered to be speculative. The default rate for lower-quality debt securities is likely to be higher during economic recessions or periods of high interest rates.

In response to market, economic, political, or other conditions, a fund may temporarily use a different investment strategy for defensive purposes. If the fund does so, different factors could affect its performance and the fund may not achieve its investment objective.

Other Investment Strategies

In addition to the principal investment strategies discussed above, the Adviser may use various techniques, such as buying and selling futures contracts and exchange traded funds, to increase or decrease the fund's exposure to changing security prices, interest rates, or other factors that affect security values. The Adviser may invest the fund's assets in investment-grade debt securities by investing in other funds.

Fundamental Investment Policies

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

Fidelity Advisor ® High Income Advantage Fund seeks a combination of a high level of income and the potential for capital gains.

Valuing Shares

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

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

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

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

NAV is calculated using the values of other open-end funds, if any, in which the fund invests (referred to as underlying funds). Shares of underlying funds are valued at their respective NAVs. Other assets are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in the Adviser's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. For example, if, in the Adviser's opinion, a security's value has been materially affected by events occurring before a fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by the Adviser in accordance with applicable fair value pricing policies. Fair value pricing will be used for high yield debt securities when available pricing information is determined to be stale or for other reasons not to accurately reflect fair value.

Arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before a fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets 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.

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

You may buy or sell shares through a retirement account or an investment professional. When you invest through a retirement account or an investment professional, the procedures for buying, selling, and exchanging shares and the account features, policies, and fees may differ. Additional fees may apply to your investment in shares, including a transaction fee if you buy or sell shares through a broker or other investment professional. Your broker may also require you to pay brokerage commissions on purchases and sales of certain share classes of the fund.

Information on Placing Orders

You should include the following information with any order:

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

Frequent Purchases and Redemptions

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

Excessive trading of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to the fund (such as brokerage commissions or spreads paid to dealers who sell money market instruments), disrupting portfolio management strategies, and diluting the value of the shares in cases in which fluctuations in markets are not fully priced into the fund's NAV.

The fund 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) 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.

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.

Qualified Wrap Programs

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).

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.

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.

Each class of the fund has different expenses and features, as described in the applicable prospectus. Investors eligible to purchase one class of shares may also be eligible to purchase other classes of shares of the fund. Your investment professional, as applicable, can help you choose the class of shares that best suits your investment needs. However, plan participants may purchase only the classes of shares that are eligible for sale and available through their plan. Certain classes may have higher expenses than those offered by the plan.

Additional Information Regarding Class Z Eligibility

Class Z shares are offered to:

1. Employee benefit plans investing through an intermediary and employee benefit plans not recordkept by Fidelity. For this purpose, employee benefit plans generally include profit sharing, 401(k), and 403(b) plans, but do not include: IRAs; SIMPLE, SEP, or SARSEP plans; plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans); health savings accounts; or plans investing through the Fidelity Advisor® 403(b) program; and

An investor transacting in such programs may be required to pay a commission and/or other forms of compensation to the broker.

Investors may be able to purchase Class Z in other circumstances. Please contact Fidelity or your investment professional for more information about Class Z shares.

There is no minimum balance or purchase minimum for Class A, Class M, Class C, Class I or Class Z shares.

Price to Buy

The price to buy one share of Class A or Class M is its offering price or its NAV, depending on whether you pay a front-end sales charge.

The price to buy one share of Class C, Class I, or Class Z is its NAV. Class C shares are sold without a front-end sales charge, but may be subject to a CDSC upon redemption. Class I and Class Z shares are sold without a sales charge.

If you pay a front-end sales charge, your price will be Class A's or Class M's offering price. When you buy Class A or Class M shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class M shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A's or Class M's NAV.

The offering price of Class A or Class M is its NAV plus the sales charge. The offering price is calculated by dividing Class A's or Class M's NAV by the difference between one and the applicable front-end sales charge percentage and rounding to the nearest cent.

The dollar amount of the sales charge for Class A or Class M is the difference between the offering price of the shares purchased and the NAV of those shares. Since the offering price per share is calculated to the nearest cent using standard rounding criteria, the percentage sales charge you actually pay may be higher or lower than the sales charge percentages shown in this prospectus due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Shares will be bought at the offering price or NAV, as applicable, next calculated after an order is received in proper form.

It is the responsibility of your investment professional to transmit your order to buy shares to Fidelity before the close of business on the day you place your order.

The 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 offering price or NAV, as applicable, 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.

The fund may stop offering shares completely or may offer shares only on a limited basis, for a period of time or permanently.

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

Shares can be bought or sold through investment professionals using an automated order placement and settlement system that guarantees payment for orders on a specified date.

Certain financial institutions that meet creditworthiness criteria established by Fidelity Distributors Corporation (FDC) may enter confirmed purchase orders on behalf of customers by phone, with payment to follow no later than close of business on the next business day. If payment is not received by that time, the order will be canceled and the financial institution will be liable for any losses.

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 of Class A, Class M, or Class C is its NAV, minus any applicable CDSC. The price to sell one share of Class I or Class Z is its NAV.

Shares will be sold at the NAV next calculated after an order is received in proper form, minus any applicable CDSC. Normally, redemptions will be processed by the next business day, but it may take up to seven days to pay the redemption proceeds if making immediate payment would adversely affect the fund.

It is the responsibility of your investment professional to transmit your order to sell shares to Fidelity before the close of business on the day you place your order.

The 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, minus any applicable CDSC. 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.

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-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:

Class Z:

When your relationship with your managed account provider 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.

Policies Concerning the Redemption of Fund Shares

If your account is held directly with a fund , the length of time that a fund typically expects to pay redemption proceeds depends on the method you have elected to receive such proceeds. A fund typically expects to make payment of redemption proceeds by wire, automated clearing house (ACH) or by issuing a check by the next business day following receipt of a redemption order in proper form. Proceeds from the periodic and automatic sale of shares of a Fidelity ® money market fund that are used to buy shares of another Fidelity ® fund are settled simultaneously.

If your account is held through an intermediary , the length of time that a fund typically expects to pay redemption proceeds depends, in part, on the terms of the agreement in place between the intermediary and a fund. For redemption proceeds that are paid either directly to you from a fund or to your intermediary for transmittal to you, a fund typically expects to make payments by wire, by ACH or by issuing a check on the next business day following receipt of a redemption order in proper form from the intermediary by a fund. Redemption orders that are processed through investment professionals that utilize the National Securities Clearing Corporation will generally settle one to three business days following receipt of a redemption order in proper form.

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

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

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

Converting Shares

The fund will automatically convert your class of shares of the fund to Class Z shares, if Class Z of the fund is available under your plan.

The fund may convert your Class Z shares to another class of shares of the fund, including classes of shares not offered in this prospectus that are available under your plan, if your plan is no longer eligible to offer Class Z. Information on the other classes of shares of the fund can be found in that class’s prospectus. Investors will be notified in writing before any such conversion to another class.

A conversion will be based on the respective NAVs of the two classes, without the imposition of any fees, on the trade date of the conversion. A conversion between share classes of the same fund is a non-taxable event.

Conversion Feature. After a maximum of 10 years from the initial date of purchase, Class C shares convert automatically to Class A shares of a fund. Conversion to Class A shares will be made at NAV. At the time of conversion, a portion of the Class C shares bought through the reinvestment of dividends or capital gains (Dividend Shares) will also convert to Class A shares. The portion of Dividend Shares that will convert is determined by the ratio of your converting Class C non-Dividend Shares to your total Class C non-Dividend Shares. A fund may convert shares sooner in certain circumstances. A shorter holding period may also apply depending on your intermediary. Please see "Sales Charge Waiver Policies Applied by Certain Intermediaries" in the "Appendix" section of this prospectus. The policy will be effective March 1, 2019, however, prior to this date, or such other date as may be determined by the Adviser, a fund will permit an intermediary to transition Class C shares to Class A shares of the same fund, regardless of holding period, if the intermediary is unable to administer this conversion policy. Such transitions to Class A shares will be made at NAV minus any applicable CDSC.

Exchanging Shares

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

As a Class A shareholder, you have the privilege of exchanging Class A shares for the same class of shares of other Fidelity ® funds that offer Advisor classes of shares at NAV or for Daily Money Class shares of Fidelity ® funds that offer Daily Money Class shares.

As a Class M shareholder, you have the privilege of exchanging Class M shares for the same class of shares of other Fidelity ® funds that offer Advisor classes of shares at NAV or for Advisor M Class shares of Fidelity ® Government Money Market Fund. If you purchased your Class M shares through certain investment professionals that have signed an agreement with FDC, you also have the privilege of exchanging your Class M shares for shares of Fidelity ® Capital Appreciation Fund.

As a Class C shareholder, you have the privilege of exchanging Class C shares for the same class of shares of other Fidelity ® funds that offer Advisor classes of shares or for Advisor C Class shares of Fidelity ® Treasury Money Market Fund.

As a Class I shareholder, you have the privilege of exchanging Class I shares for the same class of shares of other Fidelity ® funds that offer Advisor classes of shares or for shares of Fidelity ® funds.

As a Class Z shareholder, you have the privilege of exchanging Class Z shares for the same class of shares of other Fidelity ® funds that offer Advisor classes of shares or Class Z shares of other Fidelity ® funds available through your employee benefit plan, or if the Fidelity ® fund does not offer Class Z shares, then other classes of the Fidelity ® fund that are available through your plan.

Through your investment professional, you may also move between certain share classes of the same fund. For more information, see the statement of additional information (SAI) or consult your investment professional.

However, you should note the following policies and restrictions governing exchanges:

The fund may terminate or modify exchange privileges in the future.

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.

Rollover IRAs

Class Z shares generally are not available to IRA rollover accounts. Assets from retirement plans may be invested in other classes of shares of the fund through an IRA rollover, including classes of shares not offered in this prospectus. Each class of the fund has different expenses and features, and may have higher expenses than Class Z shares. Information on the other classes of shares of the fund, including any minimum purchase or balance requirements applicable to IRA rollover accounts and class expenses and features, can be found in the applicable class’s prospectus. Please contact your investment professional for more information.

Account Features and Policies

Features

The following features may be available to buy and sell shares of the fund. Visit institutional.fidelity.com or contact your investment professional for more information.

Electronic Funds Transfer (Fidelity Advisor Money Line ® ): electronic money movement through the Automated Clearing House

Wire: electronic money movement through the Federal Reserve wire system

Policies

The following apply to you as a shareholder.

Statements that Fidelity sends to you, if applicable, include the following:

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 1-877-208-0098. We will begin sending individual copies to you within 30 days of receiving your call.

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, the fund reserves the right to involuntarily redeem an account in the case of: (i) actual or suspected threatening conduct or actual or suspected fraudulent, illegal or suspicious activity by the account owner or any other individual associated with the account; or (ii) the failure of the account owner to provide information to the fund related to opening the accounts. Your shares will be sold at the NAV, minus any applicable shareholder fees, calculated on the day Fidelity closes your fund position.

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

Dividends and Capital Gain Distributions

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

The fund normally declares dividends daily and pays them monthly. The fund normally pays capital gain distributions in December.

Earning Dividends

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

When you buy shares, your method of payment will determine when dividends begin to accrue. For example, shares purchased through an investment professional using the National Securities Clearing Corporation generally begin to earn dividends on the day the fund receives payment for those shares. Shares purchased through an investment professional by any other method generally begin to earn dividends on the first business day following the day the fund receives payment. If you purchase your shares directly from the fund by check or wire, those shares generally begin to earn dividends on the first business day following the day you placed your purchase order.

Shares sold through an investment professional using the National Securities Clearing Corporation generally earn dividends until, but not including, the day redemption proceeds are processed. Shares sold through an investment professional by any other method generally earn dividends until, but not including, the first business day following the day redemption proceeds are processed. Shares sold other than through an investment professional generally earn dividends until, but not including, the first business day following the day of redemption.

Exchange requests will be processed only when both funds are open for business.

Distribution Options

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

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

2. Income-Earned Option.  Any capital gain distributions will be automatically reinvested in additional shares. Any dividends will be paid in cash.

3. Cash Option.  Any dividends and capital gain distributions will be paid in cash.

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

Not all distribution options may be available for every account and certain restrictions may apply. If the option you prefer is not listed on your account application, or if you want to change your current option, contact your investment professional directly or call Fidelity.

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.

Any dividends and capital gain distributions paid to retirement plan participants will be automatically reinvested.

Tax Consequences

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

Distributions you receive from the fund are subject to federal income tax, and may also be subject to state or local taxes.

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 the fund will normally be taxable to you when you receive them, regardless of your distribution option. If you elect to receive distributions in cash or to invest distributions automatically in the same class of shares of another Fidelity ® fund that offers Advisor classes of shares or shares of Fidelity ® funds, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Distributions by the fund to tax-advantaged retirement plan accounts are not taxable currently (but you may be taxed later, upon withdrawal of your investment from such account).

Taxes on Transactions

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 the fund generally is the difference between the cost of your shares and the price you receive when you sell them.

Exchanges within a tax-advantaged retirement plan account will not result in a capital gain or loss for federal tax purposes. Please consult your tax advisor regarding the tax treatment of distributions from a tax-advantaged retirement plan account.

Portfolio Manager(s)

Harley Lank is portfolio manager of the fund, which he has managed since September 2009. He also manages other funds. Since joining Fidelity Investments in 1996, Mr. Lank has worked as a research analyst and portfolio manager.

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

From time to time a manager, analyst, or other Fidelity employee may express views regarding a particular company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed and do not necessarily represent the views of Fidelity or any other person in the Fidelity organization. Any such views are subject to change at any time based upon market or other conditions and Fidelity disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Fidelity ® fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any Fidelity ® fund.

Advisory Fee(s)

The fund pays a management fee to the Adviser. The management fee is calculated and paid to the Adviser every month. The fee is calculated by adding a group fee rate to an individual fund fee rate, dividing by twelve, and multiplying the result by the fund's average net assets throughout the month.

The group fee rate is based on the average net assets of all the mutual funds advised by FMR. For this purpose, the average net assets of any mutual funds previously advised by FMR that currently are advised by Fidelity SelectCo, LLC are included. This rate cannot rise above 0.37%, and it drops as total assets under management increase.

For October 2018, the group fee rate was 0.11%. The individual fund fee rate is 0.45%.

The total management fee for the fiscal year ended October 31, 2018, was 0.56% of the fund's average net assets. Because the fund's management fee rate may fluctuate, the fund's management fee may be higher or lower in the future.

The Adviser pays FMRC, FMR UK, FMR H.K., and FMR Japan for providing sub-advisory services.

The basis for the Board of Trustees approving the management contract and sub-advisory agreements for the fund is available in the fund's annual report for the fiscal period ended October 31, 2018.

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

Reimbursement or waiver arrangements can decrease expenses and boost performance.

Fund Distribution

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

FDC distributes each class's shares.

Intermediaries may receive from the Adviser, FDC, and/or their affiliates compensation for their services intended to result in the sale of class shares, including compensation for providing recordkeeping and administrative services, as well as other retirement plan expenses for Class Z shares. This compensation may take the form of (as applicable):

These payments are described in more detail in this section and in the SAI. Please speak with your investment professional to learn more about any payments his or her firm may receive from the Adviser, FDC, and/or their affiliates, as well as fees and/or commissions the investment professional charges. You should also consult disclosures made by your investment professional at the time of purchase.

You may pay a sales charge when you buy or sell your Class A, Class M, and Class C shares.

FDC collects the sales charge.

As described in detail in this section, you may be entitled to a waiver of your sales charge, or to pay a reduced sales charge, when you buy or sell Class A, Class M, and Class C shares. In the event of changes in sales charges, sales charges, if any, in effect at the time of purchase generally will apply.

The availability of certain sales charge waivers and discounts may depend on whether you purchase your shares directly from a fund or through an intermediary. Intermediaries may have different policies and procedures regarding the availability of front-end sales load waivers or CDSC (back-end) waivers. Please see “Sales Charge Waiver Policies Applied by Certain Intermediaries” in the “Appendix” section of the prospectus. In all instances, it is the purchaser’s responsibility to notify a fund or the purchaser’s intermediary at the time of purchase of any relationship or other facts qualifying the purchaser for sales charge waivers or discounts. For waivers and discounts not available through a particular intermediary, shareholders will have to purchase fund shares directly from a fund or through another intermediary to receive these waivers or discounts.

The front-end sales charge will be reduced for purchases of Class A and Class M shares according to the sales charge schedules below.

When exchanging Class M shares of one fund for Class M shares of another Fidelity ® fund that offers Advisor classes of shares or Advisor M Class shares of Fidelity ® Government Money Market Fund, your Class M shares retain the CDSC schedule in effect when they were originally bought.

Class A or Class M shares purchased by an individual or company through the Combined Purchase, Rights of Accumulation, or Letter of Intent program may receive a reduced front-end sales charge according to the sales charge schedules above. To qualify for a Class A or Class M front-end sales charge reduction under one of these programs, you must notify Fidelity in advance of your purchase.

Combined Purchase, Rights of Accumulation, and Letter of Intent Programs. The following qualify as an "individual" or "company" for the purposes of determining eligibility for the Combined Purchase and Rights of Accumulation program: an individual, spouse, and their children under age 21 purchasing for his/her or their own account; a trustee, administrator, or other fiduciary purchasing for a single trust estate or a single fiduciary account or for a single or parent-subsidiary group of "employee benefit plans" (except SEP and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)) and 403(b) programs; and tax-exempt organizations (as defined in Section 501(c)(3) of the Internal Revenue Code).

File your Letter with Fidelity no later than the date of the initial purchase toward completing your Letter. Each Class A or Class M purchase you make toward completing your Letter will be entitled to the reduced front-end sales charge applicable to the total investment indicated in the Letter. Purchases of the following may be aggregated for the purpose of completing your Letter: (i) Class A and Class M shares of any Fidelity ® fund that offers Advisor classes of shares (except those acquired by exchange from Daily Money Class shares of a fund that offers Daily Money Class shares that had been previously exchanged from a Fidelity ® fund that offers Advisor classes of shares), (ii) Class C shares of any Fidelity ® fund that offers Advisor classes of shares, (iii) Advisor C Class shares of Fidelity ® Treasury Money Market Fund, and (iv) Class A Units (New and Old), Class C Units, Class D Units, and Class P Units of the Fidelity Advisor ® 529 Plan. Reinvested income and capital gain distributions will not be considered purchases for the purpose of completing your Letter. Purchases may be aggregated across multiple intermediaries for the purpose of qualifying for the Letter of Intent program. Your initial purchase toward completing your Letter must be at least 5% of the total investment specified in your Letter. Fidelity will register Class A or Class M shares equal to 5% of the total investment specified in your Letter in your name and will hold those shares in escrow. You will earn income, dividends and capital gain distributions on escrowed Class A and Class M shares. The escrow will be released when you complete your Letter. You are not obligated to complete your Letter. If you do not complete your Letter, you must pay the increased front-end sales charges due in accordance with the sales charge schedule in effect when your shares were originally bought. Fidelity may redeem sufficient escrowed Class A or Class M shares to pay any applicable front-end sales charges. If you purchase more than the amount specified in your Letter and qualify for additional Class A or Class M front-end sales charge reductions, the front-end sales charge will be adjusted to reflect your total purchase at the end of 13 months and the surplus amount will be applied to your purchase of additional Class A or Class M shares at the then-current offering price applicable to the total investment.

Detailed information about these programs also is available on institutional.fidelity.com. In order to obtain the benefit of a front-end sales charge reduction for which you may be eligible, you may need to inform your investment professional of other accounts you, your spouse, or your children maintain with your investment professional or other investment professionals from the same intermediary.

Class C shares may, upon redemption less than one year after purchase, for any reason, be assessed a CDSC of 1.00%. The actual CDSC you pay may be higher or lower than that calculated using this percentage due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investment professionals will receive as compensation from FDC, at the time of the sale, a concession equal to 1.00% of your purchase of Class C shares. A concession will not apply to Class C shares acquired through reinvestment of dividends or capital gain distributions.

The CDSC for Class A, Class M, and Class C shares will be calculated based on the lesser of the cost of each class's shares, as applicable, at the initial date of purchase or the value of those shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class A, Class M, and Class C shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC. In determining the applicability and rate of any CDSC at redemption, shares representing reinvested dividends and capital gains will be redeemed first, followed by those shares that have been held for the longest period of time.

A front-end sales charge will not apply to the following Class A or Class M shares:

  1. Purchased for an employee benefit plan other than a plan investing through the Fidelity Advisor ® 403(b) program. For this purpose, employee benefit plans generally include 401(a), 401(k), 403(b), and 457(b) governmental plans, but do not include: IRAs, SIMPLE, SEP, or SARSEP plans; or health savings accounts.
  2. Purchased for an insurance company separate account.

  4. Purchased with the proceeds of a redemption of Fidelity ® or Fidelity Advisor ® fund shares held in (i) an insurance company separate account, or (ii) an employee benefit plan (as described in waiver number 1 above, including the Fidelity Advisor ® 403(b) program), the proceeds of which must be reinvested directly into Fidelity Advisor ® fund shares held in an account for which Fidelity Management Trust Company or an affiliate serves as custodian.
  5.

If the Fidelity Advisor® account is no longer directly held at Fidelity, your intermediary may be able to apply the waiver, assuming the stated conditions are met. Please contact your investment professional for more information.
  10. Purchased for a mutual fund only brokerage platform that charges a platform entrance fee and where the distributor has agreed with the broker to participate in such platform.

Pursuant to Rule 22d-1 under the Investment Company Act of 1940 (1940 Act), FDC exercises its right to waive Class A's and Class M's front-end sales charge on shares acquired through reinvestment of dividends and capital gain distributions or in connection with a fund's merger with or acquisition of any investment company or trust. FDC also exercises its right to waive Class A's and Class M's front-end sales charge on purchases of $10.00 or less.

The CDSC may be waived on the redemption of shares (applies to Class A, Class M, and Class C, unless otherwise noted):

  1. For disability or death.
  2. From employer-sponsored retirement plans (except SIMPLE IRAs, SEPs, and SARSEPs) starting the year in which age 70½ is attained.
  3. For minimum required distributions from Traditional IRAs, Rollover IRAs, SIMPLE IRAs, SEPs, and SARSEPs (excludes Roth accounts) starting the year in which age 70½ is attained.
  4. Through the Fidelity Advisor ® Systematic Withdrawal Program, if the amount does not exceed 12% of the account balance in a rolling 12-month period.
  5. (Applicable to Class A and Class M only) Held by insurance company separate accounts.

To qualify for a Class A or Class M front-end sales charge reduction or waiver, you must notify Fidelity in advance of your purchase.

You may be required to notify Fidelity in advance of your redemption to qualify for a Class A, Class M, or Class C CDSC waiver.

Information on sales charge reductions and waivers is available free of charge on institutional.fidelity.com.

Finder's Fees. Finder's fees may be paid to investment professionals who sell Class A and Class M shares in purchase amounts of $1 million or more. For Class A share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 1.00% of the purchase amount for purchases of $1 million up to $4 million, 0.50% of the purchase amount for purchases of $4 million up to $25 million, and 0.25% of the purchase amount for purchases of $25 million or more. For Class M share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.25% of the purchase amount.

Investment professionals may be eligible for a finder's fee on the following purchases of Class A and Class M shares made through broker-dealers and banks: a trade that brings the value of the accumulated account(s) of an investor, including a 403(b) program or an employee benefit plan (except a SEP or SARSEP plan or a plan covering self-employed individuals and their employees (formerly a Keogh/H.R. 10 plan)), over $1 million; a trade for an investor with an accumulated account value of $1 million or more; and an incremental trade toward an investor's $1 million Letter. Accumulated account value for purposes of finder's fees eligibility is determined the same as it is for Rights of Accumulation. Daily Money Class shares of a fund that offers Daily Money Class shares are not counted for this purpose unless acquired by exchange from any Fidelity ® fund that offers Advisor classes of shares. For information, see "Combined Purchase, Rights of Accumulation, and Letter of Intent Programs" above.

Finder's fees are not paid in connection with purchases of Class A or Class M shares by insurance company separate accounts or managed account programs that charge an asset-based fee, or purchases of Class A or Class M shares made with the proceeds from the redemption of shares of any Fidelity ® fund or any retirement plan recordkept at Fidelity.

Investment professionals should contact Fidelity in advance to determine if they qualify to receive a finder's fee. Finder's fees will be paid in connection with shares recordkept in a Fidelity Advisor ® 401(k) Retirement Plan only at the time of the initial conversion of assets. Investment professionals should contact Fidelity for more information.

Reinstatement Privilege. If you have sold all or part of your Class A, Class M, or Class C shares of the fund, you may reinvest an amount equal to all or a portion of the redemption proceeds in the same class of the fund or another Fidelity ® fund that offers Advisor classes of shares, at the NAV next determined after receipt in proper form of your investment order, provided that such reinvestment is made within 90 days of redemption. Under these circumstances, the dollar amount of the CDSC you paid, if any, on shares will be reimbursed to you by reinvesting that amount in Class A, Class M, or Class C shares, as applicable.

You must reinstate your shares into an account with the same registration. This privilege may be exercised only once by a shareholder with respect to the fund and certain restrictions may apply. For purposes of the CDSC schedule, the holding period will continue as if the Class A, Class M, or Class C shares had not been redeemed. To qualify for the reinstatement privilege, you must notify Fidelity in writing in advance of your reinvestment.

Distribution and Service Plan(s)

Class A has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 (1940 Act). Under the plan, Class A is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class A shares. Class A may pay this 12b-1 (distribution) fee at an annual rate of 0.15% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Currently, the Trustees have not approved such payments. The Trustees may approve 12b-1 (distribution) fee payments at an annual rate of up to 0.15% of Class A's average net assets when the Trustees believe that it is in the best interests of Class A shareholders to do so.

In addition, pursuant to the Class A plan, Class A pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class A's average net assets throughout the month for providing shareholder support services.

Except as provided below, FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services. For purchases of Class A shares on which a finder's fee was paid to intermediaries, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Class M has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class M is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class M shares. Class M may pay this 12b-1 (distribution) fee at an annual rate of 0.15% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Currently, the Trustees have not approved such payments. The Trustees may approve 12b-1 (distribution) fee payments at an annual rate of up to 0.15% of Class M's average net assets when the Trustees believe that it is in the best interests of Class M shareholders to do so.

In addition, pursuant to the Class M plan, Class M pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class M's average net assets throughout the month for providing shareholder support services.

FDC may reallow up to the full amount of this 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

Class C has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. Under the plan, Class C is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class C shares. Class C currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of 0.75% of its average net assets throughout the month.

In addition, pursuant to the Class C plan, Class C pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class C's average net assets throughout the month for providing shareholder support services.

Normally, after the first year of investment, FDC may reallow up to the full amount of the 12b-1 (distribution) fees to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of the 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class C shares made through reinvestment of dividends or capital gain distributions, during the first year of investment and thereafter, FDC may reallow up to the full amount of this 12b-1 (distribution) fee paid by such shares to intermediaries, including its affiliates, for providing services intended to result in the sale of Class C shares and may reallow up to the full amount of this 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

Any fees paid out of Class A's, Class M's, and Class C's assets on an ongoing basis pursuant to a Distribution and Service Plan will increase the cost of your investment and may cost you more than paying other types of sales charges.

In addition to the above payments, each Class A, Class M, and Class C plan specifically recognizes that the Adviser may make payments from its management fee revenue, past profits, or other resources to FDC for expenses incurred in connection with providing services intended to result in the sale of Class A, Class M, and Class C shares and/or shareholder support services. The Adviser, directly or through FDC or one or more affiliates, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class A, Class M, and Class C.

Each of Class I and Class Z has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act that recognizes that the Adviser may use its management fee revenues, as well as its past profits or its resources from any other source, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of Class I and Class Z shares and/or shareholder support services. The Adviser, directly or through FDC, may pay significant amounts to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class I and Class Z.

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