Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Many stock and bond markets around the world have been unsettled of late; however, volatility can often lead to opportunity for patient investors. Financial markets are always unpredictable, but there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best-performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Annual Report

Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of the fund's dividend income and capital gains (the profits earned upon the sale of securities that have grown in value) and assuming a constant rate of performance each year. The $10,000 table and the fund's returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund's total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Average Annual Total Returns

Periods ended August 31, 2007	Past 1 year	Past 5 years	Past 10 years
Fidelity® Export and Multinational Fund	15.51%	15.65%	11.77%

$10,000 Over 10 Years

Let's say hypothetically that $10,000 was invested in Fidelity® Export and Multinational Fund on August 31, 1997. The chart shows how the value of your investment would have changed, and also shows how the Standard & Poor's 500^SM (S&P 500®) Index performed over the same period.

Management's Discussion of Fund Performance

Comments from Victor Thay, Portfolio Manager of Fidelity® Export and Multinational Fund

Most broad-based U.S. stock market benchmarks posted double-digit advances for the 12-month period ending August 31, 2007. Volatility was intense during that span, however, with multiple peaks and valleys. The Dow Jones Industrial Average^SM - an often-quoted measure of the overall U.S. equity market - reflected the turbulence. The Dow had nearly 30 single-day gains of more than 100 points, but also lost over 100 points on more than 20 occasions, the vast majority of which occurred in the final three months of the period. Investors who weathered the storm came out well, as the Dow gained 20.03% for the 12 months overall. The NASDAQ Composite® Index finished close behind, returning 19.80%. The strong performance of technology stocks, accounting for roughly half of the benchmark's weighting on average during the period, helped bolster its results. The Standard & Poor's 500^SM Index also did very well, rising 15.13%. The biggest thorn in the side of equity performance during the period was a burgeoning credit crunch, spurred mainly by the crisis in the subprime mortgage loan market.

The fund outpaced the benchmark S&P 500® for the year with a total return of 15.51%. Productive stock selection and significant overweightings in the energy and information technology sectors combined to provide a sizable boost to the fund's return versus the index, as did favorable currency movements from our overseas investments. Among the top contributors were energy services providers Schlumberger and National Oilwell Varco, consumer electronics giant Apple, Internet paid-search leader Google and Taiwanese electronics contract manufacturer Hon Hai Precision Industry. Good stock picking in the materials sector also helped, with genetically modified seed maker Monsanto high on the list of contributors. Conversely, the biggest detractor from relative performance was Countrywide Financial, one of the nation's largest mortgage originators, whose stock price fell by about 40% during the period due to concerns about deteriorating credit quality in the subprime mortgage market. A few weak performers in the pharmaceuticals, biotechnology and life science segment of health care, including biotech pioneer Genentech, also dragged on the fund's relative return, as did some inopportune picks in the semiconductors and semiconductor equipment space, including British chip maker CSR, which I ultimately sold.

The views expressed above reflect those of the portfolio manager(s) only through the end of the period as stated on the cover of this report 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.

Annual Report

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (March 1, 2007 to August 31, 2007).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Investments - continued

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value March 1, 2007	Ending Account Value August 31, 2007	Expenses Paid During Period* March 1, 2007 to August 31, 2007
Actual	$ 1,000.00	$ 1,072.50	$ 4.23
Hypothetical (5% return per year before expenses)	$ 1,000.00	$ 1,021.12	$ 4.13

* Expenses are equal to the Fund's annualized expense ratio of .81%; multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

For the period ended August 31, 2007

(Amounts in thousands except ratios)

1. Organization.

Fidelity Export and Multinational Fund (the Fund) is a fund of Fidelity Summer Street Trust (the trust) (formerly a fund of Fidelity Union Street Trust) and is authorized to issue an unlimited number of shares.

Effective, April 19, 2007, the Board of Trustees approved an Agreement and Plan of Reorganization whereby the Fund reorganized into Fidelity Summer Street Trust effective June 29, 2007 (Trust Reorganization). The Trust Reorganization not impact the Fund's investment strategies or Fidelity Management & Research Company's (FMR) management of the Fund. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by FMR and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete list of holdings for each Fidelity Central Fund is available upon request or at the SEC's web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the SEC's web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value (NAV) per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments.

Annual Report

Notes to Financial Statements - continued

(Amounts in thousands except ratios)

3. Significant Accounting Policies - continued

Security Valuation - continued

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. For example, when developments occur between the close of a market and the close of the NYSE that may materially affect the value of some or all of the securities, or when trading in a security is halted, those securities may be fair valued. Factors used in the determination of fair value may include monitoring news to identify significant market or security specific events such as changes in the value of U.S. securities markets, reviewing developments in foreign markets and evaluating the performance of ADRs, futures contracts and exchange-traded funds. Because the Fund's utilization of fair value pricing depends on market activity, the frequency with which fair value pricing is used cannot be predicted and may be utilized to a significant extent. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities.

Foreign Currency. The Fund uses foreign currency contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rate at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

3. Significant Accounting Policies - continued

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, the Fund will claim a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to foreign currency transactions, market discount, deferred trustees compensation and losses deferred due to wash sales and excise tax regulations.

Total	$ 9,702	$ 233,527

Short-Term Trading (Redemption) Fees. Shares held in the Fund less than 30 days are subject to a redemption fee equal to .75% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by FMR, are retained by the Fund and accounted for as an addition to paid in capital.

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management has concluded that the adoption of FIN 48 will not result in a material impact on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

Annual Report

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $2,035,117 and $2,619,956, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .30% of the Fund's average net assets and a group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annual management fee rate was .56% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FSC receives account fees and asset-based fees that vary according to account size and type of account. FSC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period the transfer agent fees were equivalent to an annual rate of .22% of average net assets.

Accounting and Security Lending Fees. FSC maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for the month.

6. Fees and Other Transactions with Affiliates - continued

Accounting and Security Lending Fees - continued

Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $8 for the period.

Interfund Lending Program. Pursuant to an Exemptive Order issued by the SEC, the Fund, along with other registered investment companies having management contracts with FMR, may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from, or lend money to, other participating affiliated funds. At period end, there were no interfund loans outstanding. The Fund's activity in this program during the period for which loans were outstanding was as follows:

Borrower or Lender	Average Daily Loan Balance	Weighted Average Interest Rate	Interest Expense
Borrower	$ 6,974	5.41%	$ 5

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $10 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Security Lending.

The Fund lends portfolio securities from time to time in order to earn additional income. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are

disclosed on the Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Net income from lending portfolio securities during the period amounted to $1,583.

9. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $193 for the period. In addition, through arrangements with the Fund's custodian and transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody and transfer agent expenses by $1 and $136, respectively.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

The United States Securities and Exchange Commission ("SEC") is conducting an investigation of FMR (covering the years 2002 to 2004) arising from gifts, gratuities and business entertainment provided by certain brokers to certain individuals who were employed on FMR's domestic equity trading desk during that period. FMR is in discussions with the SEC staff regarding the possible resolution of the matter, but as of period-end no final resolution has been reached.

In December 2006, the Independent Trustees completed their own investigation of the matter with the assistance of independent counsel. The Independent Trustees and FMR agree that, despite the absence of proof that the Fidelity mutual funds experienced diminished execution quality as a result of the improper receipt of gifts and business entertainment, the conduct at issue was serious and is worthy of redress. Accordingly, the Independent Trustees have requested and FMR has agreed to pay $42 million to Fidelity mutual funds, plus interest to be determined at the time that payment is made. A method of allocating this payment among the funds has not yet been determined. The total

payment to the Fund is not anticipated to have a material impact on the Fund's net assets. In addition, FMR reimbursed related legal expenses which are recorded in the accompanying Statement of Operations as an expense reduction.

Annual Report

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Export and Multinational Fund

On April 19, 2007, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve the management contract and subadvisory agreements (together, the Advisory Contracts) for the fund in connection with reorganizing the fund from one Trust to another. The Board reached this determination because the contractual terms of and fees payable under the fund's Advisory Contracts are identical to those in the fund's current Advisory Contracts. The Advisory Contracts involve no changes in (i) the investment process or strategies employed in the management of the fund's assets; (ii) the nature or level of services provided under the fund's Advisory Contracts; or (iii) the day-to-day management of the fund or the persons primarily responsible for such management. The Board considered that it approved the Advisory Contracts for the fund during the past year and that it will again consider renewal of the Advisory Contracts in July 2007.

Because the Board was approving Advisory Contracts with terms identical to the current Advisory Contracts, it did not consider the fund's investment performance, competitiveness of management fee and total expenses, costs of services and profitability, or economies of scale to be significant factors in its decision.

In connection with its future renewal of the fund's Advisory Contracts, the Board will consider: (i) the nature, extent, and quality of services provided to the fund, including shareholder and administrative services and investment performance; (ii) the competitiveness of the fund's management fee and total expenses; (iii) the costs of the services and profitability, including the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering, and servicing the fund and its shareholders; and (iv) whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies.

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the fund's Advisory Contracts are fair and reasonable, and that the fund's Advisory Contracts should be approved, without modification, as part of the process of reorganizing the fund from one Trust to another.

Each year, typically in July, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information throughout the year.

The Board meets regularly each month except August and takes into account throughout the year matters bearing on Advisory Contracts. The Board, acting directly and through its separate committees, considers at each of its meetings factors that are relevant to the annual renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. At the time of the renewal, the Board had 12 standing committees, each composed of Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. Each committee has adopted a written charter outlining the structure and purposes of the committee. One such committee, the Equity Contract Committee, meets periodically as needed throughout the year to consider matters specifically related to the annual renewal of Advisory Contracts. The committee requests and receives information on, and makes recommendations to the Independent Trustees concerning, the approval and annual review of the Advisory Contracts.

Annual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

At its July 2007 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the Advisory Contracts for the fund. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the management fee and total expenses of the fund; (iii) the total costs of the services to be provided by and the profits to be realized by the investment adviser and its affiliates from the relationship with the fund; (iv) the extent to which economies of scale would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders. The Board also approved amendments to the fund's agreements with foreign sub-advisers to clarify that each sub-adviser provides services as an independent contractor.

In determining whether to renew the Advisory Contracts for the fund, the Board ultimately reached a determination, with the assistance of fund counsel and Independent Trustees' counsel, that the renewal of the Advisory Contracts and the compensation to be received by Fidelity under the management contract is consistent with Fidelity's fiduciary duty under applicable law. In addition to evaluating the specific factors noted above, the Board, in reaching its determination, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by competitors to Fidelity, and that the fund's shareholders, with the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Nature, Extent, and Quality of Services Provided. The Board considered staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the background of the fund's portfolio manager and the fund's investment objective and discipline. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives.

Annual Report

Resources Dedicated to Investment Management and Support Services. The Board reviewed the size, education, and experience of the Investment Advisers' investment staff, their use of technology, and the Investment Advisers' approach to recruiting, training, and retaining portfolio managers and other research, advisory, and management personnel. The Board considered Fidelity's extensive global research capabilities that enable the Investment Advisers to aggregate data from various sources in an effort to produce positive investment results. The Board noted that Fidelity's analysts have access to a variety of technological tools that enable them to perform both fundamental and quantitative analysis and to specialize in various disciplines. The Board also considered that Fidelity's portfolio managers and analysts have access to daily portfolio attribution that allows for monitoring of a fund's portfolio, as well as an electronic communication system that provides immediate real-time access to research concerning issuers and credit enhancers.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, distribution, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the Investment Advisers' supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services. The Board also considered that Fidelity voluntarily pays for market data out of its own resources. The Board also considered the agreement reached between the Independent Trustees and Fidelity in December 2006 following an independent review of matters relating to receipt of travel, entertainment, gifts and gratuities in violation of Fidelity policies.

The Board noted that the growth of fund assets across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through phone representatives and over the Internet, and investor education materials and asset allocation tools.

Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing for a large variety of mutual fund investor services. For example, fund shareholders are offered the privilege of exchanging shares of the fund for shares of other Fidelity funds, as set forth in the fund's prospectus, without paying a sales charge. The Board noted that, since the last Advisory Contract renewals in July 2006, Fidelity has taken a number of actions that benefited particular funds, including (i) dedicating additional resources to investment research and to restructure the investment research teams; (ii) contractually agreeing to reduce the management fee on Fidelity Advisor Floating Rate High Income Fund; (iii) contractually agreeing to reduce the management fees on Fidelity's California, Massachusetts, New Jersey, and New York AMT Tax-Free Money Market Funds, launching new Institutional Classes and Service Classes of these funds, and contractually agreeing to impose expense limitations on these funds; (iv) eliminating the exchange fee on the Fidelity Select Portfolios and reducing the pricing and bookkeeping fee rates for these funds; (v) reducing the maximum transfer agency fee rates on high income funds and certain equity funds; (vi) proposing amended management contracts that, if approved by shareholders, will add a performance adjustment component to the management fees paid by 18 Fidelity Advisor equity funds; (vii) contractually agreeing to reduce fees for Ultra-Short Central Fund and the money market Central Funds; (viii) waiving the Fidelity Advisor funds' contingent deferred sales charge on certain redemptions made through systematic withdrawal programs; and (ix) amending the management contracts for equity and fixed-income funds whose management contracts incorporate a "group fee" structure by adding four new fee "breakpoints" to the group fee rate schedules.

Investment Performance and Compliance. The Board considered whether the fund has operated within its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance, as well as the fund's relative investment performance measured against (i) a broad-based securities market index, and (ii) a custom peer group of mutual funds deemed appropriate by the Board over multiple periods. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2006, the fund's cumulative total returns, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a custom peer group of mutual funds defined by FMR based on categories assigned by Morningstar, Inc. The box within each chart shows the 25th percentile return (bottom of box) and the 75th percentile return (top of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund. The fund's custom peer group, defined by FMR, is a peer group that FMR believes provides a more meaningful performance comparison than the peer group assigned by Morningstar, Inc. Morningstar, Inc. assigns mutual funds to categories based on their investment styles as measured by their underlying portfolio holdings.

Annual Report

Fidelity Export and Multinational Fund

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of the fund was in the fourth quartile for the one-year period and the first quartile for the three- and five-year periods. The Board also stated that the investment performance of the fund compared favorably to its benchmark for the three- and five-year periods, although the fund's one-year cumulative total return was lower than its benchmark.

The Board considered that FMR has taken steps to refocus and strengthen equity research, equity portfolio management, and compliance.

Based on its review, and giving particular weight to the nature and quality of the resources dedicated by the Investment Advisers to maintain and improve relative performance, the Board concluded that the nature, extent, and quality of the services provided to the fund will benefit the fund's shareholders, particularly in light of the Board's view that the fund's shareholders benefit from investing in a fund that is part of a large family of funds offering a variety of investment disciplines and services.

Competitiveness of Management Fee and Total Fund Expenses. The Board considered the fund's management fee and total expenses compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared. The Board also considered supplemental information about how the fund's management fee and total expenses ranked relative to groups based on Lipper classifications, which take into account a fund's market capitalization and style.

Annual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors, in terms of gross management fees before expense reimbursements or caps. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 10% means that 90% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked, is also included in the chart and considered by the Board.

Fidelity Export and Multinational Fund

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2006.

Based on its review, the Board concluded that the fund's management fee was fair and reasonable in light of the services that the fund receives and the other factors considered.

Annual Report

In its review of the fund's total expenses, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses. As part of its review, the Board also considered current and historical total expenses of the fund compared to competitive fund median expenses. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the fund's total expenses ranked below its competitive median for 2006.

In its review of total expenses, the Board also considered Fidelity fee structures and other information on clients that FMR and its affiliates service in other competitive markets, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients.

Based on its review, the Board concluded that the fund's total expenses were reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the audited books and records of Fidelity. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of the results of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board believes that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

Annual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

The Board has also reviewed Fidelity's non-fund businesses and any fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and determined that the amount of profit is a fair entrepreneurial profit for the management of the fund.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions, including reductions that occur through operation of the transfer agent agreement. The transfer agent fee varies in part based on the number of accounts in the fund. If the number of accounts decreases or the average account size increases, the overall transfer agent fee rate decreases.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR determines the group fee rates based on a tiered asset "breakpoint" schedule. In connection with the renewal of the fund's management contract, the Board approved amendments to the fund's management contract that added four new fee breakpoints to the group fee rate schedule for assets under FMR's management above $1,386 billion. The Board considered that the group fee rate declines under both the present and amended schedules, but that under the amended schedule, the group fee rate declines faster as assets under FMR's management exceed $1,386 billion. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will achieve a certain level of economies of scale as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board further concluded that any potential economies of scale are being shared between fund shareholders and Fidelity in an appropriate manner.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on several topics, including (i) fund performance trends and actions to be taken by FMR to improve certain funds' overall performance; (ii) Fidelity's portfolio manager compensation structure, including its effects on fund profitability and the extent to which portfolio manager compensation is linked to fund performance; (iii) Fidelity's fee structures; (iv) the funds' sub-advisory arrangements; and (v) accounts managed by Fidelity other than the Fidelity funds.

Annual Report

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.

(e) (1) Audit Committee Pre-Approval Policies and Procedures:

The trust's Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The trust's Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee's consideration of non-audit services by the audit firms that audit the Fidelity funds. The policies and procedures require that any non-audit service provided by a fund audit firm to a Fidelity Fund and any non-audit service provided by a fund auditor to a Fund Service Provider that relates directly to the operations and financial reporting of a Fidelity fund (Covered Service) are subject to approval by the Audit Committee before such service is provided. Non-audit services provided by a fund audit firm for a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund (Non-Covered Service) but that are expected to exceed $50,000 are also subject to pre-approval by the Audit Committee.

All Covered Services, as well as Non-Covered Services that are expected to exceed $50,000, must be approved in advance of provision of the service either: (i) by formal resolution of the Audit Committee, or (ii) by oral or written approval of the service by the Chair of the Audit Committee (or if the Chair is unavailable, such other member of the Audit Committee as may be designated by the Chair to act in the Chair's absence). The approval contemplated by (ii) above is permitted where the Treasurer determines that action on such an engagement is necessary before the next meeting of the Audit Committee. Neither pre-approval nor advance notice of Non-Covered Service engagements for which fees are not expected to exceed $50,000 is required; such engagements are to be reported to the Audit Committee monthly.

(e) (2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Audit-Related Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended August 31, 2007 and August 31, 2006 on behalf of the fund.

There were no amounts that were required to be approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended August 31, 2007 and August 31, 2006 on behalf of the Fund Service Providers that relate directly to the operations and financial reporting of the fund.

(h) The trust's Audit Committee has considered Non-Covered Services that were not pre-approved that were provided by PwC to Fund Service Providers to be compatible with maintaining the independence of PwC in its audit of the fund, taking into account representations from PwC, in accordance with Independence Standards Board Standard No.1, regarding its independence from the fund and its related entities.
