Fund Summary

Investment Summary

Investment Objective

Advisor High Yield Fund seeks a combination of a high level of income and the potential for capital gains.

Principal Investment Strategies

Fidelity Management & Research Company (FMR)'s principal investment strategies include:

  • Normally investing at least 65% of total assets in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities.
  • Potentially investing in non-income producing securities, including defaulted securities and common stocks.
  • Investing up to 35% of total assets in common stocks.
  • Investing in companies in troubled or uncertain financial condition.
  • Investing in domestic and foreign issuers.
  • Using fundamental analysis of each issuer's financial condition and industry position and market and economic conditions to select investments.

Principal Investment Risks

The fund is subject to the following principal investment risks:

  • Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market can react differently to these developments.
  • Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.
  • Foreign Exposure. Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
  • Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. Lower-quality debt securities (those of less than investment-grade quality) 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 can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

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.

When you sell your shares of the fund, they could be worth more or less than what you paid for them.

A portion of the brokerage commissions that the fund pays is used to reduce the fund's expenses. In addition, through arrangements with the fund's custodian, credits realized as a result of uninvested cash balances are used to reduce custodian expenses. Including these reductions, the total Class A, Class T, Class B, and Class C operating expenses are shown in the table below.

Investment Objective

Advisor High Yield Fund seeks a combination of a high level of income and the potential for capital gains.

Principal Investment Strategies

FMR normally invests at least 65% of the fund's total assets in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities. Many lower-quality debt securities are subject to legal or contractual restrictions limiting FMR's ability to resell the securities to the general public. FMR may also invest the fund's assets in non-income producing securities, including defaulted securities and common stocks. FMR currently intends to limit common stocks to 35% of the fund's total assets. FMR may invest in companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings.

FMR 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, FMR 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.

FMR 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. FMR may invest the fund's assets in investment-grade debt securities by investing in other funds. If FMR'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 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, mortgage and other asset-backed securities, and loans and loan participations.

Principal Investment Risks

Many factors affect the fund's performance. The fund's yield and share price change daily based on changes in interest rates and market conditions 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 of the fund, they could be worth more or less than what you paid for them.

Prospectus

Fund Basics - continued

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. In the short term, equity prices can fluctuate dramatically in response to these developments. Different parts of the market and different types of equity securities can react differently to these developments. For example, 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.

Interest Rate Changes. Debt 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 mortgage securities can be more sensitive to interest rate changes. In other words, the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. In addition, 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.

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 currencies; 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.

Issuer-Specific Changes. Changes in the financial condition of an issuer, 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 affect the credit quality or value of an issuer's securities. 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) and certain types of other securities tend to be particularly sensitive to these changes.

Prospectus

Fund Basics - continued

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 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. 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, FMR may temporarily use a different investment strategy for defensive purposes. If FMR does so, different factors could affect the fund's performance and the fund may not achieve its investment objective.

Fundamental Investment Policies

The policy discussed below is fundamental, that is, subject to change only by shareholder approval.

Advisor High Yield 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 New York Stock Exchange (NYSE) is open.

A class's net asset value per share (NAV) is the value of a single share. Fidelity normally calculates each class's NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. However, NAV may be calculated earlier if trading on the NYSE is restricted or as permitted by the Securities and Exchange Commission (SEC). The fund's assets are valued as of this time for the purpose of computing each class's NAV.

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.

The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value.

Buying Shares

The price to buy one share of Class A or Class T is the class's offering price or the class's NAV, depending on whether you pay a front-end sales charge.

For Class B or Class C, the price to buy one share is the class's NAV. Class B and Class C shares are sold without a front-end sales charge, but may be subject to a CDSC upon redemption.

If you pay a front-end sales charge, your price will be Class A's or Class T's offering price. When you buy Class A or Class T shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class T shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A's or Class T's NAV.

The offering price of Class A or Class T is its NAV divided by the difference between one and the applicable front-end sales charge percentage. Class A has a maximum front-end sales charge of 4.75% of the offering price. Class T has a maximum front-end sales charge of 3.50% of the offering price.

Your shares will be bought at the next offering price or NAV, as applicable, calculated after your 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.

Short-term or excessive trading into and out of the fund may harm performance by disrupting portfolio management strategies and by increasing expenses. Accordingly, the fund may reject any purchase orders, including exchanges, particularly from market timers or investors who, in FMR's opinion, have a pattern of short-term or excessive trading or whose trading has been or may be disruptive to the fund. For these purposes, FMR may consider an investor's trading history in the fund or other Fidelity funds, and accounts under common ownership or control.

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

When you place an order to buy shares, note the following:

  • All of your purchases must be made in U.S. dollars and checks must be drawn on U.S. banks.
  • Fidelity does not accept cash.
  • When making a purchase with more than one check, each check must have a value of at least $50.
  • Fidelity reserves the right to limit the number of checks processed at one time.
  • Fidelity must receive payment within three business days after an order for shares is placed; otherwise your purchase order may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.
  • If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Shareholder Information - continued

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.

If payment is not received by that time, the order will be canceled and the financial institution will be liable for any losses.

Selling Shares

The price to sell one share of Class A, Class T, Class B, or Class C is the class's NAV, minus any applicable CDSC.

If appropriate to protect shareholders, the fund may impose a redemption fee (trading fee) on redemptions from the fund.

Any applicable CDSC is calculated based on your original redemption amount.

Prospectus

Shareholder Information - continued

Your shares will be sold at the next NAV calculated after your order is received in proper form, minus any applicable CDSC.

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.

Certain requests must include a signature guarantee. It is designed to protect you and Fidelity from fraud. Your request must be made in writing and include a signature guarantee if any of the following situations apply:

  • You wish to sell more than $100,000 worth of shares;
  • The address on your account (record address) has changed within the last 15 or 30 days, depending on your account, and you wish to sell $10,000 or more of shares;
  • You are requesting that a check be mailed to a different address than the record address;
  • You are requesting that redemption proceeds be paid to someone other than the account owner; or
  • The redemption proceeds are being transferred to a Fidelity account with a different registration.

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:

  • If you are selling some but not all of your shares, leave at least $1,000 worth of shares in the account to keep it open, except accounts not subject to account minimums.
  • Normally, redemptions will be processed by the next business day, but may take up to seven days to be processed if making immediate payment would adversely affect the fund.
  • Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected. This can take up to seven business days after a purchase.
  • Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.
  • Redemption proceeds may be paid in securities or other property rather than in cash if FMR determines it is in the best interests of the fund.
  • You will not receive interest on amounts represented by uncashed redemption checks.
  • Unless otherwise instructed, Fidelity will send a check to the record address.

To sell shares issued with certificates, call Fidelity for instructions. The fund no longer issues share certificates.

Features

The following features are available to buy and sell shares of the fund.

Automatic Investment and Withdrawal Programs. Fidelity offers convenient services that let you automatically transfer money into your account, between accounts, or out of your account.

Automatic withdrawal or exchange programs can be a convenient way to provide a consistent income flow or to move money between your investments.

  • Monthly or quarterly account statements (detailing account balances and all transactions completed during the prior month or quarter).

You may initiate many transactions by telephone or electronically. Fidelity will not be responsible for any losses 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 immediately after you receive them. 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.

Shareholder Information - continued

When you sign your account application, you will be asked to certify that your social security or taxpayer identification number is correct and that you are not subject to 31% backup withholding for failing to report income to the IRS. If you violate IRS regulations, the IRS can require the fund to withhold 31% of your taxable distributions and redemptions.

If your account balance falls below $1,000 for any reason, including solely due to declines in a class's NAV, you will be given 30 days' notice to reestablish the minimum balance. If you do not increase your balance, Fidelity may close your account and send the proceeds to you. Your shares will be sold at the NAV, minus any applicable CDSC, on the day your account is closed. Accounts not subject to account minimums will not be closed for failure to maintain a minimum balance.

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

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 Security Clearing Corporation begin to earn dividends on the day the fund receives payment for those shares. Shares purchased through an investment professional by any other method 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 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 Security Clearing Corporation earn dividends until, but not including, the day the redemption proceeds are processed. Shares sold through an investment professional by any other method earn dividends until, but not including, the first business day following the day redemptions proceeds are processed. Shares sold other than through an investment professional earn dividends until, but not including, the first business day following the day of redemption.

Distribution Options

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

Prospectus

Shareholder Information - continued

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

2. Income-Earned Option. Your capital gain distributions will be automatically reinvested in additional shares of the same class of the fund. Your dividends will be paid in cash.

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

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

Not all distribution options are available for every account. 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.

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

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.

If a fund's distributions exceed its income and capital gains realized in any year, which is sometimes the result of currency-related losses, all or a portion of those distributions may be treated as a return of capital to shareholders for tax purposes. A return of capital generally will not be taxable to you but will reduce the cost basis of your shares and result in a higher reported capital gain or a lower reported capital loss when you sell your shares.

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.

Prospectus

Shareholder Information - continued

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 Advisor fund or shares of certain Fidelity funds, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Taxes on transactions. Your redemptions, 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.

Fund Management

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

FMR is the fund's manager.

As of January 31, 2001, FMR and its affiliate, FMR Co., Inc. (FMRC), had approximately $612 billion in discretionary assets under management.

As the manager, FMR is responsible for choosing the fund's investments and handling its business affairs.

Affiliates assist FMR with foreign investments:

  • Fidelity Management & Research (U.K.) Inc. (FMR U.K.), in London, England, serves as a sub-adviser for the fund. FMR U.K. was organized in 1986 to provide investment research and advice to FMR. FMR U.K. may provide investment research and advice on issuers based outside the United States and may also provide investment advisory services for the fund.
  • Fidelity Management & Research (Far East) Inc. (FMR Far East) serves as a sub-adviser for the fund. FMR Far East was organized in 1986 to provide investment research and advice to FMR. FMR Far East may provide investment research and advice on issuers based outside the United States and may also provide investment advisory services for the fund.
  • Fidelity Investments Japan Limited (FIJ), in Tokyo, Japan, serves as a sub-adviser for the fund. As of June 30, 2001, FIJ had approximately $21.9 billion in discretionary assets under management. FIJ may provide investment research and advice on issuers based outside the United States and may also provide investment advisory and order execution services for the fund from time to time.

FMRC serves as a sub-adviser for the fund. FMRC is primarily responsible for choosing investments for the fund.

Tom Soviero is vice president and manager of Advisor High Yield, which he has managed since June 2000. He also manages institutional high-yield accounts for Fidelity. Since joining Fidelity in 1989, Mr. Soviero has worked as a research analyst, manager and director of high-yield research.

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.

The fund pays a management fee to FMR. The management fee is calculated and paid to FMR 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.

Prospectus

Fund Services - continued

The group fee rate is based on the average net assets of all the mutual funds advised by FMR. This rate cannot rise above 0.37%, and it drops as total assets under management increase.

For October 2001, the group fee rate was 0.13%. The individual fund fee rate is 0.45%.

The total management fee for the fiscal year ended October 31, 2001, was 0.58% of the fund's average net assets.

FMR pays FMRC, FMR U.K., and FMR Far East for providing sub-advisory services. FMR Far East in turn pays FIJ for providing sub-advisory services.

FMR may, from time to time, agree to reimburse a class for management fees and other expenses above a specified limit. FMR retains the ability to be repaid by a class if expenses fall below the specified limit prior to the end of the fiscal year. Reimbursement arrangements, which may be discontinued by FMR at any time, can decrease a class's expenses and boost its 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.

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

FDC collects the sales charge.

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

Class A or Class T 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 T front-end sales charge reduction under one of these programs, you must notify Fidelity in advance of your purchase. More detailed information about these programs is contained in the statement of additional information (SAI).

Combined Purchase. To receive a Class A or Class T front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class T shares with purchases of: (i) Class A, Class T, Class B, and Class C shares of any Fidelity Advisor fund and (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund.

Rights of Accumulation. To receive a Class A or Class T front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class T shares the current value of your holdings in: (i) Class A, Class T, Class B, and Class C shares of any Fidelity Advisor fund, (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund, and (iii) Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund acquired by exchange from any Fidelity Advisor fund.

Letter of Intent. You may receive a Class A or Class T front-end sales charge reduction on your purchases of Class A and Class T shares made during a 13-month period by signing a Letter of Intent (Letter). Each Class A or Class T purchase you make after you sign the 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 T shares of any Fidelity Advisor fund (except those acquired by exchange from Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund that had been previously exchanged from a Fidelity Advisor fund), (ii) Class B and Class C shares of any Fidelity Advisor fund, and (iii) Advisor B Class shares and Advisor C Class shares of Treasury Fund.

When exchanging Class B shares of one fund for Class B shares of another Fidelity Advisor fund or Advisor B Class shares of Treasury Fund, your Class B shares retain the CDSC schedule in effect when they were originally bought.

Except as provided below, investment professionals receive as compensation from FDC, at the time of sale, a concession equal to 4.00% of your purchase of Class B shares. For purchases of Class B shares through reinvested dividends or capital gain distributions, investment professionals do not receive a concession at the time of sale.

Class C shares may, upon redemption within one year of purchase, for any reason, including failure to maintain the account minimum, be assessed a CDSC of 1.00%.

Except as provided below, 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. For purchases of Class C shares made for an employee benefit plan, 403(b) program or plan covering a sole-proprietor (formerly Keogh/H.R. 10 plan) or through reinvested dividends or capital gain distributions, investment professionals do not receive a concession at the time of sale.

The CDSC for Class B and Class C shares will be calculated based on the lesser of the cost of the Class B or Class C shares, as applicable, at the initial date of purchase or the value of those Class B or Class C shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class B 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, Class B or Class C shares representing reinvested dividends and capital gains will be redeemed first, followed by those Class B or Class C shares that have been held for the longest period of time.

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

1. Purchased for an employee benefit plan (except a SIMPLE IRA, SEP, or SARSEP plan or a plan covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)) or a 403(b) program other than a Fidelity Advisor 403(b) program for which Fidelity or an affiliate serves as custodian, with at least $25 million or more in plan assets;

Special Purchase Shares. Certain Class A and Class T shares may be subject to a CDSC of 0.25% of the lesser of the cost of the shares at the date of purchase or the value of the shares at the time of redemption. These shares, referred to in this prospectus as "Special Purchase Shares," are Class A and Class T shares sold by investment professionals who receive a finder's fee from FDC equal to 0.25% of their purchase amount. Finder's fees are paid only in connection with purchases of: (i) Class A shares in amounts of $1 million or more that qualify for a Class A load waiver; (ii) Class A shares in amounts of $25 million or more; and (iii) Class T shares in amounts of $1 million or more. Finder's fees are not paid in connection with purchases of Class A or Class T shares by insurance company separate accounts.

Fund Services - continued

The CDSC will be assessed on Special Purchase Shares if they do not remain in Class A or Class T shares of the Fidelity Advisor funds, or Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund, for a period of at least one uninterrupted year. Shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC.

To determine the applicability of the CDSC, Class A, Class T, or Daily Money Class shares representing reinvested dividends and capital gains will be redeemed first, followed by Special Purchase Shares that have been held for the longest period of time. Special Purchase Shares held for less than one year will be redeemed last.

To qualify to receive a finder's fee, an investment professional must notify Fidelity in advance of the eligible purchase.

The CDSC on Special Purchase Shares will not apply to the redemption of shares:

1. Held by insurance company separate accounts;

2. For plan loans or distributions or exchanges to non-Advisor fund investment options from employee benefit plans (except shares of SIMPLE IRA, SEP, and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans) purchased on or after February 11, 1999) and 403(b) programs other than Fidelity Advisor 403(b) programs for which Fidelity or an affiliate serves as custodian; or

3. For disability, payment of death benefits, or minimum required distributions starting at age 70 1/2 from Traditional IRAs, Roth IRAs, SIMPLE IRAs, SEPs, SARSEPs, and plans covering a sole-proprietor or self-employed individuals and their employees (formerly Keogh/H.R. 10 plans).

To qualify for a Special Purchase Share CDSC waiver, you must notify Fidelity in advance of your redemption.

Reinstatement Privilege. If you have sold all or part of your Class A, Class T, Class B, 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 Advisor fund, 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 T, Class B, or Class C shares, as applicable. You must reinstate your Class A, Class T, Class B, or Class C 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 T, Class B, 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.

Conversion Feature. After a maximum of seven years from the initial date of purchase, Class B shares and any capital appreciation associated with those shares convert automatically to Class A shares of the fund. Conversion to Class A shares will be made at NAV. At the time of conversion, a portion of the Class B 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 B non-Dividend Shares to your total Class B non-Dividend Shares.

Class A has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. 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 FDC a 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 is authorized to pay FDC a monthly 12b-1 (service) fee as compensation for providing shareholder support services. Class A may pay FDC a 12b-1 (service) fee at an annual rate of 0.25% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Class A currently pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.15% of its average net assets throughout the month. Class A's 12b-1 (service) fee rate may be increased only when the Trustees believe it is in the best interests of Class A shareholders to do so.

FDC may reallow up to the full amount of the Class A 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class T has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plan, Class T is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class T shares. Class T may pay FDC a 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 T's average net assets when the Trustees believe that it is in the best interests of Class T shareholders to do so.

In addition, pursuant to the Class T plan, Class T pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class T's average net assets throughout the month for providing shareholder support services.

FDC may reallow up to the full amount of the Class T 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class B has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plan, Class B is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class B shares. Class B may pay FDC a 12b-1 (distribution) fee at an annual rate of 0.75% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Class B currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of 0.65% of its average net assets throughout the month. Class B's 12b-1 (distribution) fee rate may be increased only when the Trustees believe that it is in the best interests of Class B shareholders to do so.

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

FDC may reallow up to the full amount of the Class B 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class C has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. 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 Class C 12b-1 (distribution) fees to intermediaries (such as banks, broker-dealers, and other service-providers), 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 Class C 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class C shares made for an employee benefit plan, 403(b) program or plan covering a sole-proprietor (formerly Keogh/H.R. 10 plan) or 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 the Class C 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 the Class C 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

In addition, each plan specifically recognizes that FMR 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 the applicable class's shares and/or shareholder support services, including payments of significant amounts made to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class A, Class T, Class B, and Class C.

Because 12b-1 fees are paid out of each class's assets on an ongoing basis, they will increase the cost of your investment and may cost you more than paying other types of sales charges.

To receive sales concessions, finder's fees, and payments made pursuant to a Distribution and Service Plan, intermediaries must sign the appropriate agreement with FDC in advance.

FMR may allocate brokerage transactions in a manner that takes into account the sale of shares of the Fidelity Advisor funds, provided that the fund receives brokerage services and commission rates comparable to those of other broker-dealers.

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 fund or FDC. This prospectus and the related SAI do not constitute an offer by the fund or by FDC to sell shares of the fund to or to buy shares of the fund from any person to whom it is unlawful to make such offer.

Fund Summary

Investment Summary

Investment Objective

Advisor High Yield Fund seeks a combination of a high level of income and the potential for capital gains.

Principal Investment Strategies

Fidelity Management & Research Company (FMR)'s principal investment strategies include:

  • Normally investing at least 65% of total assets in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities.
  • Potentially investing in non-income producing securities, including defaulted securities and common stocks.
  • Investing up to 35% of total assets in common stocks.
  • Investing in companies in troubled or uncertain financial condition.
  • Investing in domestic and foreign issuers.
  • Using fundamental analysis of each issuer's financial condition and industry position and market and economic conditions to select investments.

Principal Investment Risks

The fund is subject to the following principal investment risks:

  • Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market can react differently to these developments.
  • Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.
  • Foreign Exposure. Foreign markets, particularly emerging markets, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
  • Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. Lower-quality debt securities (those of less than investment-grade quality) 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 can be more volatile due to increased sensitivity to adverse issuer, political, regulatory, market, or economic developments and can be difficult to resell.

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.

When you sell your shares of the fund, they could be worth more or less than what you paid for them.

A portion of the brokerage commissions that the fund pays is used to reduce the fund's expenses. In addition, through arrangements with the fund's custodian, credits realized as a result of uninvested cash balances are used to reduce custodian expenses. Including these reductions, the total Class A, Class T, Class B, and Class C operating expenses are shown in the table below.

Investment Objective

Advisor High Yield Fund seeks a combination of a high level of income and the potential for capital gains.

Principal Investment Strategies

FMR normally invests at least 65% of the fund's total assets in income-producing debt securities, preferred stocks, and convertible securities, with an emphasis on lower-quality debt securities. Many lower-quality debt securities are subject to legal or contractual restrictions limiting FMR's ability to resell the securities to the general public. FMR may also invest the fund's assets in non-income producing securities, including defaulted securities and common stocks. FMR currently intends to limit common stocks to 35% of the fund's total assets. FMR may invest in companies whose financial condition is troubled or uncertain and that may be involved in bankruptcy proceedings, reorganizations, or financial restructurings.

FMR 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, FMR 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.

FMR 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. FMR may invest the fund's assets in investment-grade debt securities by investing in other funds. If FMR'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 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, mortgage and other asset-backed securities, and loans and loan participations.

Principal Investment Risks

Many factors affect the fund's performance. The fund's yield and share price change daily based on changes in interest rates and market conditions 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 of the fund, they could be worth more or less than what you paid for them.

Prospectus

Fund Basics - continued

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. In the short term, equity prices can fluctuate dramatically in response to these developments. Different parts of the market and different types of equity securities can react differently to these developments. For example, 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.

Interest Rate Changes. Debt 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 mortgage securities can be more sensitive to interest rate changes. In other words, the longer the maturity of a security, the greater the impact a change in interest rates could have on the security's price. In addition, 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.

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 currencies; 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.

Issuer-Specific Changes. Changes in the financial condition of an issuer, 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 affect the credit quality or value of an issuer's securities. 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) and certain types of other securities tend to be particularly sensitive to these changes.

Prospectus

Fund Basics - continued

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 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. 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, FMR may temporarily use a different investment strategy for defensive purposes. If FMR does so, different factors could affect the fund's performance and the fund may not achieve its investment objective.

Fundamental Investment Policies

The policy discussed below is fundamental, that is, subject to change only by shareholder approval.

Advisor High Yield 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 New York Stock Exchange (NYSE) is open.

A class's net asset value per share (NAV) is the value of a single share. Fidelity normally calculates each class's NAV as of the close of business of the NYSE, normally 4:00 p.m. Eastern time. However, NAV may be calculated earlier if trading on the NYSE is restricted or as permitted by the Securities and Exchange Commission (SEC). The fund's assets are valued as of this time for the purpose of computing each class's NAV.

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.

The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value.

Buying Shares

The price to buy one share of Class A or Class T is the class's offering price or the class's NAV, depending on whether you pay a front-end sales charge.

For Class B or Class C, the price to buy one share is the class's NAV. Class B and Class C shares are sold without a front-end sales charge, but may be subject to a CDSC upon redemption.

If you pay a front-end sales charge, your price will be Class A's or Class T's offering price. When you buy Class A or Class T shares at the offering price, Fidelity deducts the appropriate sales charge and invests the rest in Class A or Class T shares of the fund. If you qualify for a front-end sales charge waiver, your price will be Class A's or Class T's NAV.

The offering price of Class A or Class T is its NAV divided by the difference between one and the applicable front-end sales charge percentage. Class A has a maximum front-end sales charge of 4.75% of the offering price. Class T has a maximum front-end sales charge of 3.50% of the offering price.

Your shares will be bought at the next offering price or NAV, as applicable, calculated after your 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.

Short-term or excessive trading into and out of the fund may harm performance by disrupting portfolio management strategies and by increasing expenses. Accordingly, the fund may reject any purchase orders, including exchanges, particularly from market timers or investors who, in FMR's opinion, have a pattern of short-term or excessive trading or whose trading has been or may be disruptive to the fund. For these purposes, FMR may consider an investor's trading history in the fund or other Fidelity funds, and accounts under common ownership or control.

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

When you place an order to buy shares, note the following:

  • All of your purchases must be made in U.S. dollars and checks must be drawn on U.S. banks.
  • Fidelity does not accept cash.
  • When making a purchase with more than one check, each check must have a value of at least $50.
  • Fidelity reserves the right to limit the number of checks processed at one time.
  • Fidelity must receive payment within three business days after an order for shares is placed; otherwise your purchase order may be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.
  • If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees the fund or Fidelity has incurred.

Shareholder Information - continued

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.

Selling Shares

The price to sell one share of Class A, Class T, Class B, or Class C is the class's NAV, minus any applicable CDSC.

If appropriate to protect shareholders, the fund may impose a redemption fee (trading fee) on redemptions from the fund.

Any applicable CDSC is calculated based on your original redemption amount.

Prospectus

Shareholder Information - continued

Your shares will be sold at the next NAV calculated after your order is received in proper form, minus any applicable CDSC.

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.

Certain requests must include a signature guarantee. It is designed to protect you and Fidelity from fraud. Your request must be made in writing and include a signature guarantee if any of the following situations apply:

  • You wish to sell more than $100,000 worth of shares;
  • The address on your account (record address) has changed within the last 15 or 30 days, depending on your account, and you wish to sell $10,000 or more of shares;
  • You are requesting that a check be mailed to a different address than the record address;
  • You are requesting that redemption proceeds be paid to someone other than the account owner; or
  • The redemption proceeds are being transferred to a Fidelity account with a different registration.

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:

  • If you are selling some but not all of your shares, leave at least $1,000 worth of shares in the account to keep it open, except accounts not subject to account minimums.
  • Normally, redemptions will be processed by the next business day, but may take up to seven days to be processed if making immediate payment would adversely affect the fund.
  • Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected. This can take up to seven business days after a purchase.
  • Redemptions may be suspended or payment dates postponed when the NYSE is closed (other than weekends or holidays), when trading on the NYSE is restricted, or as permitted by the SEC.
  • Redemption proceeds may be paid in securities or other property rather than in cash if FMR determines it is in the best interests of the fund.
  • You will not receive interest on amounts represented by uncashed redemption checks.
  • Unless otherwise instructed, Fidelity will send a check to the record address.

To sell shares issued with certificates, call Fidelity for instructions. The fund no longer issues share certificates.

  • Any exchanges of Class A, Class T, Class B, and Class C shares are not subject to a CDSC.
  • Before exchanging into a fund or class, read its prospectus.
  • The fund or class you are exchanging into must be available for sale in your state.

Account Features and Policies

Features

The following features are available to buy and sell shares of the fund.

Automatic Investment and Withdrawal Programs. Fidelity offers convenient services that let you automatically transfer money into your account, between accounts, or out of your account.

Automatic withdrawal or exchange programs can be a convenient way to provide a consistent income flow or to move money between your investments.

You may initiate many transactions by telephone or electronically. Fidelity will not be responsible for any losses 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 immediately after you receive them. 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.

When you sign your account application, you will be asked to certify that your social security or taxpayer identification number is correct and that you are not subject to 31% backup withholding for failing to report income to the IRS. If you violate IRS regulations, the IRS can require the fund to withhold 31% of your taxable distributions and redemptions.

If your account balance falls below $1,000 for any reason, including solely due to declines in a class's NAV, you will be given 30 days' notice to reestablish the minimum balance. If you do not increase your balance, Fidelity may close your account and send the proceeds to you. Your shares will be sold at the NAV, minus any applicable CDSC, on the day your account is closed. Accounts not subject to account minimums will not be closed for failure to maintain a minimum balance.

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

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 Security Clearing Corporation begin to earn dividends on the day the fund receives payment for those shares. Shares purchased through an investment professional by any other method 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 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 Security Clearing Corporation earn dividends until, but not including, the day the redemption proceeds are processed. Shares sold through an investment professional by any other method earn dividends until, but not including, the first business day following the day redemptions proceeds are processed. Shares sold other than through an investment professional earn dividends until, but not including, the first business day following the day of redemption.

Distribution Options

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

Prospectus

Shareholder Information - continued

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

2. Income-Earned Option. Your capital gain distributions will be automatically reinvested in additional shares of the same class of the fund. Your dividends will be paid in cash.

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

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

Not all distribution options are available for every account. 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.

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

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.

If a fund's distributions exceed its income and capital gains realized in any year, which is sometimes the result of currency-related losses, all or a portion of those distributions may be treated as a return of capital to shareholders for tax purposes. A return of capital generally will not be taxable to you but will reduce the cost basis of your shares and result in a higher reported capital gain or a lower reported capital loss when you sell your shares.

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.

Prospectus

Shareholder Information - continued

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 Advisor fund or shares of certain Fidelity funds, you will receive certain December distributions in January, but those distributions will be taxable as if you received them on December 31.

Taxes on transactions. Your redemptions, 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.

Fund Management

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

FMR is the fund's manager.

As of January 31, 2001, FMR and its affiliate, FMR Co., Inc. (FMRC), had approximately $612 billion in discretionary assets under management.

As the manager, FMR is responsible for choosing the fund's investments and handling its business affairs.

Affiliates assist FMR with foreign investments:

  • Fidelity Management & Research (U.K.) Inc. (FMR U.K.), in London, England, serves as a sub-adviser for the fund. FMR U.K. was organized in 1986 to provide investment research and advice to FMR. FMR U.K. may provide investment research and advice on issuers based outside the United States and may also provide investment advisory services for the fund.
  • Fidelity Management & Research (Far East) Inc. (FMR Far East) serves as a sub-adviser for the fund. FMR Far East was organized in 1986 to provide investment research and advice to FMR. FMR Far East may provide investment research and advice on issuers based outside the United States and may also provide investment advisory services for the fund.
  • Fidelity Investments Japan Limited (FIJ), in Tokyo, Japan, serves as a sub-adviser for the fund. As of June 30, 2001, FIJ had approximately $21.9 billion in discretionary assets under management. FIJ may provide investment research and advice on issuers based outside the United States and may also provide investment advisory and order execution services for the fund from time to time.

FMRC serves as a sub-adviser for the fund. FMRC is primarily responsible for choosing investments for the fund.

Tom Soviero is vice president and manager of Advisor High Yield, which he has managed since June 2000. He also manages institutional high-yield accounts for Fidelity. Since joining Fidelity in 1989, Mr. Soviero has worked as a research analyst, manager and director of high-yield research.

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.

The fund pays a management fee to FMR. The management fee is calculated and paid to FMR 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.

Prospectus

Fund Services - continued

The group fee rate is based on the average net assets of all the mutual funds advised by FMR. This rate cannot rise above 0.37%, and it drops as total assets under management increase.

For October 2001, the group fee rate was 0.13%. The individual fund fee rate is 0.45%.

The total management fee for the fiscal year ended October 31, 2001, was 0.58% of the fund's average net assets.

FMR pays FMRC, FMR U.K., and FMR Far East for providing sub-advisory services. FMR Far East in turn pays FIJ for providing sub-advisory services.

FMR may, from time to time, agree to reimburse a class for management fees and other expenses above a specified limit. FMR retains the ability to be repaid by a class if expenses fall below the specified limit prior to the end of the fiscal year. Reimbursement arrangements, which may be discontinued by FMR at any time, can decrease a class's expenses and boost its 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.

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

FDC collects the sales charge.

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

Class A or Class T 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 T front-end sales charge reduction under one of these programs, you must notify Fidelity in advance of your purchase. More detailed information about these programs is contained in the statement of additional information (SAI).

Combined Purchase. To receive a Class A or Class T front-end sales charge reduction, if you are a new shareholder, you may combine your purchase of Class A or Class T shares with purchases of: (i) Class A, Class T, Class B, and Class C shares of any Fidelity Advisor fund and (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund.

Rights of Accumulation. To receive a Class A or Class T front-end sales charge reduction, if you are an existing shareholder, you may add to your purchase of Class A or Class T shares the current value of your holdings in: (i) Class A, Class T, Class B, and Class C shares of any Fidelity Advisor fund, (ii) Advisor B Class shares and Advisor C Class shares of Treasury Fund, and (iii) Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund acquired by exchange from any Fidelity Advisor fund.

Letter of Intent. You may receive a Class A or Class T front-end sales charge reduction on your purchases of Class A and Class T shares made during a 13-month period by signing a Letter of Intent (Letter). Each Class A or Class T purchase you make after you sign the 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 T shares of any Fidelity Advisor fund (except those acquired by exchange from Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund that had been previously exchanged from a Fidelity Advisor fund), (ii) Class B and Class C shares of any Fidelity Advisor fund, and (iii) Advisor B Class shares and Advisor C Class shares of Treasury Fund.

When exchanging Class B shares of one fund for Class B shares of another Fidelity Advisor fund or Advisor B Class shares of Treasury Fund, your Class B shares retain the CDSC schedule in effect when they were originally bought.

Except as provided below, investment professionals receive as compensation from FDC, at the time of sale, a concession equal to 4.00% of your purchase of Class B shares. For purchases of Class B shares through reinvested dividends or capital gain distributions, investment professionals do not receive a concession at the time of sale.

Class C shares may, upon redemption within one year of purchase, for any reason, including failure to maintain the account minimum, be assessed a CDSC of 1.00%.

Except as provided below, 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. For purchases of Class C shares made for an employee benefit plan, 403(b) program or plan covering a sole-proprietor (formerly Keogh/H.R. 10 plan) or through reinvested dividends or capital gain distributions, investment professionals do not receive a concession at the time of sale.

The CDSC for Class B and Class C shares will be calculated based on the lesser of the cost of the Class B or Class C shares, as applicable, at the initial date of purchase or the value of those Class B or Class C shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class B 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, Class B or Class C shares representing reinvested dividends and capital gains will be redeemed first, followed by those Class B or Class C shares that have been held for the longest period of time.

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

1. Purchased for an employee benefit plan (except a SIMPLE IRA, SEP, or SARSEP plan or a plan covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans)) or a 403(b) program other than a Fidelity Advisor 403(b) program for which Fidelity or an affiliate serves as custodian, with at least $25 million or more in plan assets;

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

To qualify for a Class B or Class C CDSC waiver, you must notify Fidelity in advance of your redemption.

Special Purchase Shares. Certain Class A and Class T shares may be subject to a CDSC of 0.25% of the lesser of the cost of the shares at the date of purchase or the value of the shares at the time of redemption. These shares, referred to in this prospectus as "Special Purchase Shares," are Class A and Class T shares sold by investment professionals who receive a finder's fee from FDC equal to 0.25% of their purchase amount. Finder's fees are paid only in connection with purchases of: (i) Class A shares in amounts of $1 million or more that qualify for a Class A load waiver; (ii) Class A shares in amounts of $25 million or more; and (iii) Class T shares in amounts of $1 million or more. Finder's fees are not paid in connection with purchases of Class A or Class T shares by insurance company separate accounts.

Fund Services - continued

The CDSC will be assessed on Special Purchase Shares if they do not remain in Class A or Class T shares of the Fidelity Advisor funds, or Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund, for a period of at least one uninterrupted year. Shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC.

To determine the applicability of the CDSC, Class A, Class T, or Daily Money Class shares representing reinvested dividends and capital gains will be redeemed first, followed by Special Purchase Shares that have been held for the longest period of time. Special Purchase Shares held for less than one year will be redeemed last.

To qualify to receive a finder's fee, an investment professional must notify Fidelity in advance of the eligible purchase.

The CDSC on Special Purchase Shares will not apply to the redemption of shares:

1. Held by insurance company separate accounts;

2. For plan loans or distributions or exchanges to non-Advisor fund investment options from employee benefit plans (except shares of SIMPLE IRA, SEP, and SARSEP plans and plans covering self-employed individuals and their employees (formerly Keogh/H.R. 10 plans) purchased on or after February 11, 1999) and 403(b) programs other than Fidelity Advisor 403(b) programs for which Fidelity or an affiliate serves as custodian; or

3. For disability, payment of death benefits, or minimum required distributions starting at age 70 1/2 from Traditional IRAs, Roth IRAs, SIMPLE IRAs, SEPs, SARSEPs, and plans covering a sole-proprietor or self-employed individuals and their employees (formerly Keogh/H.R. 10 plans).

To qualify for a Special Purchase Share CDSC waiver, you must notify Fidelity in advance of your redemption.

Reinstatement Privilege. If you have sold all or part of your Class A, Class T, Class B, 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 Advisor fund, 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 T, Class B, or Class C shares, as applicable. You must reinstate your Class A, Class T, Class B, or Class C 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 T, Class B, 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.

Conversion Feature. After a maximum of seven years from the initial date of purchase, Class B shares and any capital appreciation associated with those shares convert automatically to Class A shares of the fund. Conversion to Class A shares will be made at NAV. At the time of conversion, a portion of the Class B 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 B non-Dividend Shares to your total Class B non-Dividend Shares.

Class A has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. 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 FDC a 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 is authorized to pay FDC a monthly 12b-1 (service) fee as compensation for providing shareholder support services. Class A may pay FDC a 12b-1 (service) fee at an annual rate of 0.25% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Class A currently pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.15% of its average net assets throughout the month. Class A's 12b-1 (service) fee rate may be increased only when the Trustees believe it is in the best interests of Class A shareholders to do so.

FDC may reallow up to the full amount of the Class A 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class T has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plan, Class T is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class T shares. Class T may pay FDC a 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 T's average net assets when the Trustees believe that it is in the best interests of Class T shareholders to do so.

In addition, pursuant to the Class T plan, Class T pays FDC a monthly 12b-1 (service) fee at an annual rate of 0.25% of Class T's average net assets throughout the month for providing shareholder support services.

FDC may reallow up to the full amount of the Class T 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class B has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plan, Class B is authorized to pay FDC a monthly 12b-1 (distribution) fee as compensation for providing services intended to result in the sale of Class B shares. Class B may pay FDC a 12b-1 (distribution) fee at an annual rate of 0.75% of its average net assets, or such lesser amount as the Trustees may determine from time to time. Class B currently pays FDC a monthly 12b-1 (distribution) fee at an annual rate of 0.65% of its average net assets throughout the month. Class B's 12b-1 (distribution) fee rate may be increased only when the Trustees believe that it is in the best interests of Class B shareholders to do so.

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

FDC may reallow up to the full amount of the Class B 12b-1 (service) fee to intermediaries (such as banks, broker-dealers, and other service-providers), including its affiliates, for providing shareholder support services.

Class C has adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. 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 Class C 12b-1 (distribution) fees to intermediaries (such as banks, broker-dealers, and other service-providers), 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 Class C 12b-1 (service) fee to intermediaries, including its affiliates, for providing shareholder support services.

For purchases of Class C shares made for an employee benefit plan, 403(b) program or plan covering a sole-proprietor (formerly Keogh/H.R. 10 plan) or 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 the Class C 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 the Class C 12b-1 (service) fee paid by such shares to intermediaries, including its affiliates, for providing shareholder support services.

In addition, each plan specifically recognizes that FMR 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 the applicable class's shares and/or shareholder support services, including payments of significant amounts made to intermediaries that provide those services. Currently, the Board of Trustees of the fund has authorized such payments for Class A, Class T, Class B, and Class C.

Because 12b-1 fees are paid out of each class's assets on an ongoing basis, they will increase the cost of your investment and may cost you more than paying other types of sales charges.

To receive sales concessions, finder's fees, and payments made pursuant to a Distribution and Service Plan, intermediaries must sign the appropriate agreement with FDC in advance.

FMR may allocate brokerage transactions in a manner that takes into account the sale of shares of the Fidelity Advisor funds, provided that the fund receives brokerage services and commission rates comparable to those of other broker-dealers.

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 fund or FDC. This prospectus and the related SAI do not constitute an offer by the fund or by FDC to sell shares of the fund to or to buy shares of the fund from any person to whom it is unlawful to make such offer.
