Fund Summary

Fund:
Fidelity^® Institutional Short-Intermediate Government Fund
(name change to "Fidelity^® Limited Term Government Fund" effective August 1, 2013)

Investment Objective

The fund seeks a high level of current income in a manner consistent with preserving principal.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees
(fees paid directly from your investment) None

Annual fund operating expenses
(expenses that you pay each year as a % of the value of your investment)

Management fee	0.45%
Distribution and/or Service (12b-1) fees	None
Other expenses	0.00%
Total annual fund operating expenses	0.45%

This example helps compare the cost of investing in the fund with the cost of investing in other mutual funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

1 year	$ 46
3 years	$ 144
5 years	$ 252
10 years	$ 567

Portfolio Turnover

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 138% of the average value of its portfolio.

Principal Investment Strategies

• Normally investing at least 80% of assets in U.S. Government securities and repurchase agreements for those securities.
• Investing in U.S. Government securities issued by entities that are chartered or sponsored by Congress but whose securities are neither issued nor guaranteed by the U.S. Treasury.
• Investing in instruments related to U.S. Government securities.
• Managing the fund to have similar overall interest rate risk to the Barclays^® U.S. 1-5 Year Government Bond Index.
• Normally maintaining a dollar-weighted average maturity between two and five years.
• Allocating assets across different market sectors and maturities.
• Analyzing the credit quality of the issuer, security-specific features, current and potential future valuation, and trading opportunities to select investments.

Principal Investment Risks

• Interest Rate Changes. Interest rate increases can cause the price of a debt security to decrease.
• Prepayment. The ability of an issuer of a debt security to repay principal prior to a security's maturity can cause greater price volatility if interest rates change.
• Issuer-Specific Changes. The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.

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. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. You could lose money by investing in the fund.

Performance

The following information is intended to help you understand the risks of investing in the fund. The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index over various periods of time. The index description appears in the Additional Information about the Index section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.

Fund Basics

Investment Details

Investment Objective

The fund seeks a high level of current income in a manner consistent with preserving principal.

Principal Investment Strategies

FMR normally invests the fund's assets in U.S. Government securities and instruments related to U.S. Government securities. Certain issuers of U.S. Government securities are sponsored or chartered by Congress but their securities are neither issued nor guaranteed by the U.S. Treasury. FMR normally invests at least 80% of the fund's assets in U.S. Government securities and repurchase agreements for those securities. FMR does not currently intend to invest more than 40% of the fund's assets in mortgage securities.

FMR uses the Barclays U.S. 1-5 Year Government Bond Index as a guide in structuring the fund and selecting its investments. FMR manages the fund to have similar overall interest rate risk to the index.

FMR considers other factors when selecting the fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the fund's exposure to various risks, including interest rate risk, FMR considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the fund's competitive universe and internal views of potential future market conditions.

In addition, the fund normally maintains a dollar-weighted average maturity between two and five years. As of November 30, 2012, the fund's dollar-weighted average maturity was approximately 4.1 years and the index's dollar-weighted average maturity was approximately 2.8 years. In determining a security's maturity for purposes of calculating the fund's average maturity, an estimate of the average time for its principal to be paid may be used. This can be substantially shorter than its stated maturity.

FMR allocates the fund's assets among different market sectors (for example, U.S. Treasury or U.S. Government agency securities) and different maturities based on its view of the relative value of each sector or maturity.

In addition to the principal investment strategies discussed above, FMR may engage in transactions that have a leveraging effect on the fund, including investments in derivatives, regardless of whether the fund may own the asset, instrument, or components of the index underlying the derivative, and forward-settling securities. If the fund invests a significant portion of its assets in derivatives, its investment exposure could far exceed the value of its portfolio securities and its investment performance could be primarily dependent upon securities it does not own. The fund's derivative investments may include interest rate swaps, total return swaps, credit default swaps, options (including options on futures and swaps), and futures contracts (both long and short positions) on securities, other instruments, and indexes. Depending on FMR's outlook and market conditions, FMR may engage in these transactions to increase or decrease the fund's exposure to changing security prices, interest rates, credit qualities, or other factors that affect security values, or to gain or reduce exposure to an asset, instrument, or index.

Fund Basics - continued

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

Description of Principal Security Types

Debt securities are used by issuers to borrow money. The issuer usually pays a fixed, variable, or floating rate of interest, and must repay the amount borrowed, usually at the maturity of the security. Some debt securities, such as zero coupon bonds, do not pay current interest but are sold at a discount from their face values.

U.S. Government securities are high-quality securities issued or guaranteed by the U.S. Treasury or by an agency or instrumentality of the U.S. Government. U.S. Government securities may be backed by the full faith and credit of the U.S. Treasury, the right to borrow from the U.S. Treasury, or the agency or instrumentality issuing or guaranteeing the security. Certain issuers of U.S. Government securities, including Fannie Mae, Freddie Mac, and the Federal Home Loan Banks, are sponsored or chartered by Congress but their securities are neither issued nor guaranteed by the U.S. Treasury. U.S. Government securities include mortgage and other asset-backed securities.

A repurchase agreement is an agreement to buy a security at one price and a simultaneous agreement to sell it back at an agreed-upon price.

Derivatives are investments whose values are tied to an underlying asset, instrument, currency, or index. Derivatives include futures, options, forwards, and swaps, such as interest rate swaps (exchanging a floating rate for a fixed rate), total return swaps (exchanging a floating rate for the total return of a security or index) and credit default swaps (buying or selling credit default protection).

Forward-settling securities involve a commitment to purchase or sell specific securities when issued, or at a predetermined price or yield. Payment and delivery take place after the customary settlement period.

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. It is important to note that neither the fund's share price nor its yield is guaranteed by the U.S. Government. Unlike individual debt securities, which typically pay principal at maturity, the value of an investment in the fund will fluctuate. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money by investing in the fund.

Prospectus

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

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.

Prepayment. Many types of debt securities, including mortgage securities, are subject to prepayment risk. Prepayment risk occurs when the issuer of a security can repay principal prior to the security's maturity. Securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. In addition, the potential impact of prepayment features on the price of a debt security can be difficult to predict and result in greater volatility.

Issuer-Specific Changes. Changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular type of security or issuer, and changes in general economic or political conditions can increase the risk of default by an issuer or counterparty, which can affect a security's or instrument's credit quality or value.

Leverage Risk. Derivatives and forward-settling securities involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Leverage can magnify investment risks and cause losses to be realized more quickly. A small change in the underlying asset, instrument, or index can lead to a significant loss. Assets segregated to cover these transactions may decline in value and are not available to meet redemptions. Forward-settling securities also involve the risk that a security will not be issued, delivered, or paid for when anticipated. Government legislation or regulation could affect the use of these transactions and could limit a fund's ability to pursue its investment strategies.

In response to market, economic, political, or other conditions, 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 following policy is fundamental, that is, subject to change only by shareholder approval:

The fund seeks a high level of current income in a manner consistent with preserving principal.

Shareholder Notice

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

The fund normally invests at least 80% of its assets in U.S. Government securities and repurchase agreements for those securities.

Valuing Shares

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

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

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

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

Shares of open-end funds in which the fund may invest (referred to as underlying funds) are valued at their respective NAVs. The fund's NAV is calculated using the values of any underlying funds in which it invests. Other assets (as well as assets held by an underlying Fidelity non-money market fund) are valued primarily on the basis of market quotations, official closing prices, or information furnished by a pricing service. Certain short-term securities are valued on the basis of amortized cost. If market quotations, official closing prices, or information furnished by a pricing service are not readily available or, in FMR's opinion, are deemed unreliable for a security, then that security will be fair valued in good faith by FMR in accordance with applicable fair value pricing policies. For example, if, in FMR's opinion, a security's value has been materially affected by events occurring before the fund's pricing time but after the close of the exchange or market on which the security is principally traded, then that security will be fair valued in good faith by FMR in accordance with applicable fair value pricing policies. Assets held by an underlying Fidelity money market fund are valued on the basis of amortized cost.

Arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before a fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of a fund's NAV by short-term traders.

Prospectus

Although the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.

Fair value pricing is based on subjective judgments and it is possible that the fair value of a security may differ materially from the value that would be realized if the security were sold.

Additional Information about the Purchase and Sale of Shares

General Information

Fidelity Investments was established in 1946 to manage one of America's first mutual funds. Today, Fidelity is one of the world's largest providers of financial services.

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

You may buy or sell shares of a fund through a Fidelity brokerage account or a Fidelity mutual fund account. If you buy or sell shares of a fund (other than by exchange) through a Fidelity brokerage account, your transactions generally involve your Fidelity brokerage core (a settlement vehicle included as part of your Fidelity brokerage account).

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

You may also buy or sell shares of the fund through a retirement account (such as an IRA or an account funded through salary deduction) or an investment professional. Retirement specialists are available at 1-800-544-4774 to answer your questions about Fidelity retirement products. If you buy or sell shares of a fund through a retirement account or an investment professional, the procedures for buying, selling, and exchanging shares of the fund and the account features and policies may differ from those discussed in this prospectus. Fees in addition to those discussed in this prospectus may also apply. For example, you may be charged a transaction fee if you buy or sell shares of the fund through a non-Fidelity broker or other investment professional.

You should include the following information with any order to buy, sell, or exchange shares:

• Your name;
• Your account number;
• Name of fund whose shares you want to buy or sell; and
• Dollar amount or number of shares you want to buy or sell.

Certain methods of contacting Fidelity, such as by telephone or electronically, may be unavailable or delayed (for example, during periods of unusual market activity). In addition, the level and type of service available may be restricted based on criteria established by Fidelity.

Excessive Trading Policy

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

Prospectus

Shareholder Information - continued

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

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

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

Exceptions

The following transactions are exempt from the fund's excessive trading policy described above: (i) transactions of $1,000 or less, (ii) systematic withdrawal and/or contribution programs, (iii) mandatory retirement distributions, and (iv) transactions initiated by a plan sponsor or sponsors of certain employee benefit plans or other related accounts. In addition, the fund's excessive trading policy does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund of fund(s), or other strategy funds. A qualified fund of fund(s) is a mutual fund, qualified tuition program, or other strategy fund consisting of qualified plan assets that either applies the Fidelity fund's excessive trading policies to shareholders at the fund of fund(s) level, or demonstrates that the fund of fund(s) has an investment strategy coupled with policies designed to control frequent trading that are reasonably likely to be effective as determined by the Fidelity fund's Treasurer.

Omnibus Accounts

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

Prospectus

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

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

Retirement Plans

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

Qualified Wrap Programs

The fund will monitor aggregate trading activity of adviser transactions to attempt to identify excessive trading in qualified wrap programs, as defined below. Excessive trading by an adviser will lead to fund blocks and the wrap program will lose its qualified status. Adviser transactions will not be matched with client-directed transactions unless the wrap program ceases to be a qualified wrap program (but all client-directed transactions will be subject to the fund's excessive trading policy). A qualified wrap program is: (i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, (ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and (iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.

Prospectus

Shareholder Information - continued

Other Information about the Excessive Trading Policy

The fund reserves the right at any time to restrict purchases or exchanges or impose conditions that are more restrictive on excessive or disruptive trading than those stated in this prospectus. The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency. The fund reserves the right to modify its policies at any time without prior notice.

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

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

Buying Shares

The price to buy one share of the fund is its NAV. The fund's shares are sold without a sales charge.

Your shares will be bought at the NAV next calculated after your investment is received in proper form.

The fund has authorized certain intermediaries to accept orders to buy shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be bought at the NAV next calculated after the order is received by the authorized intermediary. Orders by funds of funds for which FMR or an affiliate serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

There is no minimum balance or purchase minimum for investments through Portfolio Advisory Services, a mutual fund or a qualified tuition program for which FMR or an affiliate serves as investment manager, certain Fidelity retirement accounts funded through salary deduction, or fund positions opened with the proceeds of distributions from such retirement accounts or from a Fidelity systematic withdrawal service. In addition, the fund may waive or lower purchase minimums in other circumstances.

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

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

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

Under applicable anti-money laundering regulations and other federal regulations, purchase orders may be suspended, restricted, or canceled and the monies may be withheld.

Prospectus

Selling Shares

The price to sell one share of the fund is its NAV.

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

The fund has authorized certain intermediaries to accept orders to sell shares on its behalf. When authorized intermediaries receive an order in proper form, the order is considered as being placed with the fund, and shares will be sold at the NAV next calculated after the order is received by the authorized intermediary. Orders by funds of funds for which FMR or an affiliate serves as investment manager will be treated as received by the fund at the same time that the corresponding orders are received in proper form by the funds of funds.

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

• When you wish to sell more than $100,000 worth of shares;
• When the address on your account (record address) has changed within the last 15 days or you are requesting that a check be mailed to an address different than the record address;
• When you are requesting that redemption proceeds be paid to someone other than the account owner; or
• In certain situations when the redemption proceeds are being transferred to a Fidelity mutual fund account with a different registration.

You should be able to obtain a signature guarantee from a bank, broker (including Fidelity Investor Centers), dealer, credit union (if authorized under state law), securities exchange or association, clearing agency, or savings association. A notary public cannot provide a signature guarantee.

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

• If you are selling some but not all of your shares, keep your fund balance above the required minimum to keep your fund position open, except fund positions not subject to balance minimums.
• Redemption proceeds (other than exchanges) may be delayed until money from prior purchases sufficient to cover your redemption has been received and collected.
• 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.

Prospectus

Shareholder Information - continued

• You will not receive interest on amounts represented by uncashed redemption checks.
• If you hold your shares in a Fidelity mutual fund account and your redemption check remains uncashed for more than one year, the check may be invested in additional shares of the fund at the NAV next calculated on the day of the investment.
• Under applicable anti-money laundering regulations and other federal regulations, redemption requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

To sell shares issued with certificates, call Fidelity for instructions. The fund does not currently issue share certificates.

Exchanging Shares

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

As a shareholder, you have the privilege of exchanging shares of the fund for shares of other Fidelity funds.

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

• The exchange limit may be modified for accounts held by certain institutional retirement plans to conform to plan exchange limits and Department of Labor regulations. See your retirement plan materials for further information.
• The fund may refuse any exchange purchase for any reason. For example, the fund may refuse exchange purchases by any person or group if, in FMR's judgment, the fund would be unable to invest the money effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.
• Before exchanging into a fund, read its prospectus.
• The fund you are exchanging into must be available for sale in your state.
• Exchanges may have tax consequences for you.
• If you are exchanging between accounts that are not registered in the same name, address, and taxpayer identification number (TIN), there may be additional requirements.
• Under applicable anti-money laundering regulations and other federal regulations, exchange requests may be suspended, restricted, canceled, or processed and the proceeds may be withheld.

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

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

Electronic copies of most financial reports and prospectuses are available at Fidelity's web site. To participate in Fidelity's electronic delivery program, call Fidelity or visit Fidelity's web site for more information.

You may initiate many transactions by telephone or electronically. Fidelity will not be responsible for any loss, cost, expense, or other liability resulting from unauthorized transactions if it follows reasonable security procedures designed to verify the identity of the investor. Fidelity will request personalized security codes or other information, and may also record calls. For transactions conducted through the Internet, Fidelity recommends the use of an Internet browser with 128-bit encryption. You should verify the accuracy of your confirmation statements upon receipt and notify Fidelity immediately of any discrepancies in your account activity. If you do not want the ability to sell and exchange by telephone, call Fidelity for instructions.

You may also be asked to provide additional information in order for Fidelity to verify your identity in accordance with requirements under anti-money laundering regulations. Accounts may be restricted and/or closed, and the monies withheld, pending verification of this information or as otherwise required under these and other federal regulations.

Fidelity may deduct a small balance maintenance fee of $12.00 from a fund balance with a value of less than $2,000 in shares. It is expected that fund balances will be valued after November 1 but prior to December 31 of each calendar year. Fund positions opened after September 30 will not be subject to the fee for that calendar year. The fee, which is payable to Fidelity, is designed to offset in part the relatively higher costs of servicing smaller fund positions. This fee will not be deducted from fund positions opened after January 1 of that calendar year if those positions use certain regular investment plans.

If your fund balance falls below $2,000 worth of shares ($500 for fund balances in Fidelity Simplified Employee Pension-IRA and Keogh accounts, and Non-Fidelity Prototype Retirement accounts) for any reason, including solely due to declines in NAV, and you do not increase your balance, Fidelity may sell all of your shares and send the proceeds to you after providing you with at least 30 days' notice to reestablish the minimum balance. Your shares will be sold at the NAV on the day Fidelity closes your fund position. Certain fund positions are not subject to these balance requirements and 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 January and December.

Earning Dividends

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

Shares generally begin to earn dividends on the first business day following the day of purchase.

Shares generally earn dividends until, but not including, the next business day following the day of redemption.

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

Distribution Options

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

1. Reinvestment Option. Your dividends and capital gain distributions will be automatically reinvested in additional shares 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 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 shares of another identically registered Fidelity fund. Your capital gain distributions will be automatically invested in shares of another identically registered Fidelity fund, automatically reinvested in additional shares of the fund, or paid in cash.

If the distribution option you prefer is not listed on your account application, or if you want to change your current distribution option, visit Fidelity's web site at www.fidelity.com or call 1-800-544-6666 for more information.

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.

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

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.

Prospectus

Shareholder Information - continued

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. Because the fund's income is primarily derived from interest, dividends from the fund generally will not qualify for the long-term capital gains tax rates available to individuals.

If a fund's distributions exceed its income and capital gains realized in any year, 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.

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 shares of another Fidelity fund, 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.

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.

Fund Services - continued

If payments made by FMR to FDC or to intermediaries under the Distribution and Service Plan were considered to be paid out of the fund's assets on an ongoing basis, they might increase the cost of your investment and might cost you more than paying other types of sales charges.

For example, FDC may offer merchandise, discounts, vouchers, or similar items to investors who purchase shares of certain Fidelity funds during certain periods.
