Chairman's Message

(photo_of_Abigail_P_Johnson)

Dear Shareholder:

Following a year in which the investment environment was volatile but generally supportive of most major asset classes, 2011 has begun on a positive note. U.S. equities gained ground in January and February, reaching their highest point since June 2008, amid indications the U.S. economy had turned a corner. Still, questions remained about the longer-term outlook, most notably persistently high unemployment. Financial markets are always unpredictable, of course, but there also are several time-tested investment principles that can help put the 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 can be tax advantages and cost benefits to consider as well. 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 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 "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 by phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

(The chairman's signature appears here.)

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 distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) 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 February 28, 2011	Past 1 year	Past 5 years	Past 10 years
Fidelity® Four-in-One Index Fund	20.68%	3.59%	4.18%

$10,000 Over 10 Years

Let's say hypothetically that $10,000 was invested in Fidelity® Four-in-One Index Fund on February 28, 2001. The chart shows how the value of your investment would have changed, and also shows how the S&P 500® Index performed over the same period.

Management's Discussion of Fund Performance

Market Recap: Steady economic growth, encouraging monetary policy, improving credit-market conditions, an uptick in merger-and-acquisition activity and better-than-expected corporate earnings propelled U.S. stock markets forward during the 12-month period ending February 28, 2011. Uncertainty over the global effects of the debt crisis in Europe and China's attempt to rein in its economy plagued equities during the spring, but markets reacted positively to the Federal Reserve's second round of stimulative quantitative easing and the Congressional midterm elections in November, followed in December by the extension of Bush-era tax policies. For the full 12 months, the large-cap-oriented S&P 500® Index advanced 22.57%, while small- and mid- cap stocks, as measured by the Dow Jones U.S. Completion Total Stock Market Index^SM, gained 32.97%. International stocks, as tracked by the MSCI® EAFE® (Europe, Australasia, Far East) Index, gained 20.16%, boosted in part by a falling U.S. dollar. Elsewhere, fixed-income investments struggled to keep pace with strong-performing equities, as investors' increased appetite for riskier assets dragged on bonds' results. For the year, the Barclays Capital® U.S. Aggregate Bond Index - a proxy for investment-grade debt - gained only 4.93%.

Comments from Andrew Dierdorf and Christopher Sharpe, Co-Portfolio Managers of Fidelity® Four-in-One Index Fund: For the 12 months ending February 28, 2011, the fund gained 20.68%, compared with 20.77% for the Fidelity Four-in-One Composite Index. Representing larger-capitalization U.S.-based stocks, all but one of the 10 sectors included in the S&P 500® Index posted a double-digit return, with materials, consumer discretionary, telecommunication services and industrials sectors delivering results in excess of 30%. Health care - the least successful sector for the period - still rose nearly 6%. With investors preferring asset classes with higher risk, smaller-capitalization stocks also performed very well, as measured by the Dow Jones U.S. Completion Total Stock Market Index^SM. Energy and materials stocks, which surged more than 51% and 41%, respectively, were the leaders among the sectors included in the Dow Jones index. In the international arena, the MSCI® EAFE® also delivered a strong return. Stocks from the most economically stable countries provided the biggest boost to overall performance, with Sweden, Denmark and Germany leading the way, while debt-burdened Greece and Ireland delivered negative returns. Turning to bonds, the Barclays Capital® U.S. Aggregate Bond Index rose roughly 5%, with most of the gain coming in the first half of the period, when investors were seeking refuge from the turmoil in the equity markets.

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, 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 (September 1, 2010 to February 28, 2011).

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. An annual index fund fee of $10 that is charged once a year may apply for certain accounts with a value of less than $10,000. Various account fees may also be payable to the custodian for certain services. These fees are not included in the table below. If they were, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by these amounts. In addition, the Fund, as a shareholder in underlying Fidelity Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity 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. An annual index fund fee of $10 that is charged once a year may apply for certain accounts with a value of less than $10,000. Various account fees may also be payable to the custodian for certain services. These fees are not included in the table below. If they were, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by these amounts. In addition, the Fund, as a shareholder in underlying Fidelity Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity 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.

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.

Annual Report

Notes to Financial Statements

For the period ended February 28, 2011

1. Organization.

Fidelity Four-in-One Index Fund (the Fund) is a fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. 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 Delaware statutory trust. The Fund invests primarily in a combination of Fidelity index funds (the Underlying Funds) managed by Fidelity Management & Research Company (FMR). Geode Capital Management, LLC serves as sub-adviser for the underlying stock funds.

2. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below.

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows. Investments in the affiliated Underlying Funds are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

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 per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and 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. Income and capital gain distributions from the Underlying Funds, if any, are recorded on the ex-dividend date.

Annual Report

2. Significant Accounting Policies - continued

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expenses included in the accompanying financial statements reflect the expenses of the Fund and do not include any expenses associated with the Underlying Funds. 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, including distributing substantially all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code and filing its U.S. federal tax return. As a result, no provision for income taxes is required. As of February 28, 2011, the Fund did not have any unrecognized tax benefits in the accompanying financial statements. A fund's federal tax return is subject to examination by the Internal Revenue Service (IRS) for a period of three years.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

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 short-term gain distributions from the Underlying Funds, capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$ 349,128,625
Gross unrealized depreciation	(14,011,151)
Net unrealized appreciation (depreciation) on securities and other investments	$ 335,117,474
Tax Cost	$ 2,089,859,544

The tax-based components of distributable earnings as of period end were as follows:

Undistributed ordinary income	$ 1,085,618
Capital loss carryforward	$ (101,079,000)
Net unrealized appreciation (depreciation)	$ 335,117,474

3. Purchases and Sales of Investments.

4. Fees and Other Transactions with Affiliates.

Management Fee. Strategic Advisers, Inc. (Strategic Advisers), an affiliate of FMR, provides the Fund with investment management related services. For these services the Fund pays a monthly management fee to Strategic Advisers. The management fee is computed at an annual rate of ..10% of the Fund's average net assets. The management fee is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees.

Other Transactions. Strategic Advisers has entered into an administration agreement with FMR under which FMR provides management and administrative services (other than investment advisory services) necessary for the operation of the Fund. Pursuant to this agreement, FMR pays all expenses of the Fund, excluding the compensation of the independent Trustees and certain other expenses such as interest expense. FMR also contracts with other Fidelity companies to perform the services necessary for the operation of the Fund. For the services under the agreement, Strategic Advisers pays FMR a monthly administration fee equal to the management fee received by Strategic Advisers, minus an amount equal to an annual rate of .02% of the Fund's average net assets. The Fund does not pay any fees for these services.

5. Expense Reductions.

FMR voluntarily agreed to reimburse expenses of the Fund to the extent annual operating expenses exceeded .08% of average net assets. Some expenses, for example interest expense, are excluded from this reimbursement. During the period this reimbursement reduced the Fund's expenses by $434,232.

Annual Report

6. 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.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Oxford Street Trust and the Shareholders of Fidelity Four-in-One Index Fund:

In our opinion, the accompanying statement of assets and liabilities, including the schedule of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Fidelity Four-in-One Index Fund (a fund of Fidelity Oxford Street Trust) at February 28, 2011, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fidelity Four-in-One Index Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at February 28, 2011 by correspondence with the transfer agent, provide a reasonable basis for our opinion.

Annual Report

Trustees and Officers

The Trustees and executive officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs Fidelity Four-in-One Index Fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee Fidelity Four-in-One Index Fund's activities, review contractual arrangements with companies that provide services to Fidelity Four-in-One Index Fund, oversee management of the risks associated with such activities and contractual arrangements, and review Fidelity Four-in-One Index Fund's performance. If the interests of Fidelity Four-in-One Index Fund and an underlying Fidelity fund were to diverge, a conflict of interest could arise and affect how the Trustees fulfill their fiduciary duties to the affected funds. Strategic Advisers has structured Fidelity Four-in-One Index Fund to avoid these potential conflicts, although there may be situations where a conflict of interest is unavoidable. In such instances, Strategic Advisers and the Trustees would take reasonable steps to minimize and, if possible, eliminate the conflict. Except for James C. Curvey, each of the Trustees oversees 190 funds advised by FMR or an affiliate. Mr. Curvey oversees 409 funds advised by FMR or an affiliate.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust. Each Trustee who is not an interested person (as defined in the 1940 Act) (Independent Trustee), shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs. The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees. The executive officers hold office without limit in time, except that any officer may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years.

Experience, Skills, Attributes, and Qualifications of the Fund's Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

Annual Report

Trustees and Officers - continued

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person (as defined in the 1940 Act) and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Kenneth L. Wolfe serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, and asset allocation funds and another Board oversees Fidelity's equity and high income funds. The asset allocation funds may invest in Fidelity funds that are overseen by such other Board. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks. The Board, acting through its committees, has charged FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above. Because the day-to-day operations and activities of the fund are carried out by or through FMR, its affiliates and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees. While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees. Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate. The responsibilities of each committee, including their oversight responsibilities, are described further under "Standing Committees of the Fund's Trustees."

Annual Report

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Four-in-One Index Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and administration agreement (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 relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and considers at each of its meetings factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established three 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. The Operations Committee, of which all of the Independent Trustees are members, meets regularly throughout the year and, among other matters, considers matters specifically related to the annual consideration of the renewal of the fund's Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its September 2010 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. 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 fund's management fee and total expenses; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its 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.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation to be received by Fidelity under the management contract is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, 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 Fidelity's competitors, 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.

Annual Report

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, Strategic Advisers, Inc. (Strategic Advisers), and the administrator, FMR, including the backgrounds of the fund's investment personnel 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 to act in the best interest of the fund.

Resources Dedicated to Investment Management and Support Services. The Board reviewed the size, education, and experience of Strategic Advisers' investment staff, their use of technology, and Strategic Advisers' and FMR's approach to recruiting, training, and retaining portfolio managers and other research, advisory, and management personnel. The Board noted FMR's continued focus on strengthening the organization and discipline of equity portfolio management and research.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by FMR and its 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 FMR's 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 noted that the growth of fund assets over time 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 telephone 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 a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) dedicating additional resources to investment research and restructuring and broadening the focus of the investment research teams; (ii) bolstering the senior management team that oversees asset management; (iii) launching Class F of certain funds as a lower-fee class available to Freedom K and Freedom Index Funds; (iv) lowering the initial investment minimums and ongoing balance requirements for Real Estate High Income Fund; (v) eliminating subsequent purchase minimums for all funds and adding a waiver of the investment minimum requirement for new accounts opened with the proceeds of a systematic withdrawal plan; (vi) eliminating the withdrawal minimum and maximum limits for systematic withdrawals from Advisor funds; (vii) expanding sales load waivers on Class A shares for Destiny Planholders and expanding Institutional Class eligibility for Class O Destiny Planholders; and (viii) changing certain Class A and Class T sales charge structures to further align them with industry practices.

Investment Performance. The Board considered whether the fund has operated in accordance with 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 over multiple periods against a proprietary custom index. The Board noted that FMR does not believe that a meaningful peer group exists against which to compare the fund's performance. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2009, the fund's cumulative total returns and the cumulative total returns of a proprietary custom index ("benchmark"). The fund's proprietary custom index is an index developed by FMR that represents the performance of the indexes to which the underlying funds seek to correspond and is based on the target weightings of each underlying fund in the fund.

Fidelity Four-in-One Index Fund

Annual Report

The Board noted that the investment performance of the fund was lower than its benchmark for all the periods shown, but considered that the performance of the fund and benchmark may vary due to valuation differences or due to fees and transaction costs, which apply to the fund but not to the benchmark. The Board also reviewed the fund's performance since inception as well as performance in the current year.

Based on its review, and giving particular weight to the nature and quality of the resources dedicated by Strategic Advisers and FMR to maintain and improve relative performance and factoring in the unprecedented market events in recent years, the Board concluded that the nature, extent, and quality of investment management and support services and of shareholder and administrative 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.

Management Fee. 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 40% means that 60% 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. For a more meaningful comparison of management fees, the fund is compared on the basis of a hypothetical "net management fee," which is derived by subtracting payments made by FMR (under the administration agreement) for non-management expenses (including pricing and bookkeeping fees and fees paid to non-affiliated custodians) from the fund's all-inclusive fee. In this regard, the Board realizes that net management fees can vary from year to year because of differences in non-management expenses.

Annual Report

Management Fees - continued

Fidelity Four-in-One Index Fund

The Board noted that the fund's hypothetical net management fee ranked below the median of its Total Mapped Group and above the median of its ASPG for 2009. The Board considered that the fund provides investors access to four aggressively priced underlying index funds at a low investment minimum and that investing in these index funds separately would require a higher combined minimum.

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

Total Expenses. In its review of the fund's total expenses, the Board considered the fund's hypothetical net management fee as well as the fund's all-inclusive fee. The Board also considered other expenses, such as pricing and bookkeeping fees and custodial, legal, and audit fees paid by FMR under the administration agreement. 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 2009.

Annual Report

Fees Charged to Other Fidelity Clients. The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. In March 2010, the Board created an ad hoc joint committee with the board of other Fidelity funds (the Committee) to review and compare Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Based on its review of total expenses and fees charged to other Fidelity clients, 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, including the findings of the Committee.

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 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.

The Board has also reviewed Fidelity's non-fund businesses and 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 were satisfied that the profitability was not excessive in the circumstances.

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.

In February 2009, the Board and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, considering the findings of the Economies of Scale Committee, that any potential economies of scale are being appropriately shared between fund shareholders and Fidelity.

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 certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) Fidelity's fund profitability methodology and profitability trends for certain funds; (iii) portfolio manager changes that have occurred during the past year and the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (iv) Fidelity's compensation structure for portfolio managers, research analysts, and other key personnel, including its effects on fund profitability, the rationale for the compensation structure, and the extent to which current market conditions have affected retention and recruitment; (v) the compensation paid by FMR to fund sub-advisers on behalf of the Fidelity funds; (vi) Fidelity's fee structures and rationale for recommending different fees among different categories of funds and classes, as well as Fidelity's voluntary waiver of fees to maintain minimum yields for certain funds and classes; (vii) the rationale for any differences between fund fee structures and fee structures in place for other Fidelity clients; and (viii) explanations regarding the relative total expenses borne by certain funds and classes, total expense competitive trends, and actions that might be taken by FMR to reduce total expenses for certain funds and classes or to achieve further economies of scale.

Annual Report

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

Billed By	February 28, 2011 A	February 28, 2010 A
PwC	$4,955,000	$4,280,000

^A Amounts may reflect rounding.

The trust's Audit Committee has considered non-audit 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 Public Company Accounting Oversight Board rules, regarding its independence from the Fund and its related entities and FMR's review of the appropriateness and permissibility under applicable law of such non-audit services prior to their provision to the Fund Service Providers.

Audit Committee Pre-Approval Policies and Procedures

The trust's Audit Committee must pre-approve all audit and non-audit services provided by a fund's 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 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.

All Covered Services 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.

Non-audit services provided by a fund audit firm to a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund are reported to the Audit Committee on a periodic basis.

Non-Audit Services Approved Pursuant to Rule 2-01(c)(7)(i)(C) and (ii) of Regulation S-X ("De Minimis Exception")

There were no non-audit services approved or required to be approved by the Audit Committee pursuant to the De Minimis Exception during the Fund's last two fiscal years relating to services provided to (i) the Fund or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Fund.

EX-99.CODE ETH

EXHIBIT EX-99.CODE ETH

FIDELITY FUNDS' CODE OF ETHICS FOR

PRESIDENT, TREASURER AND PRINCIPAL ACCOUNTING OFFICER

I. Purposes of the Code/Covered Officers

This document constitutes the Code of Ethics ("the Code") adopted by the Fidelity Funds (the "Funds") pursuant to the provisions of Rule 30b2-1(a) under the Investment Company Act of 1940), which Rule implements Sections 406 of the Sarbanes-Oxley Act of 2002 with respect to registered investment companies. The Code applies to the Fidelity Funds' President and Treasurer, and Chief Financial Officer (the "Covered Officers"). Fidelity's Ethics Office, a part of Fidelity Enterprise Compliance within Risk Oversight, administers the Code.

The purposes of the Code are to deter wrongdoing and to promote, on the part of the Covered Officers:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;
• full, fair, accurate, timely and understandable disclosure in reports and documents that the Fidelity Funds submit to the Securities and Exchange Commission ("SEC"), and in other public communications by a Fidelity Fund;
• compliance with applicable laws and governmental rules and regulations;
• the prompt internal reporting to an appropriate person or persons identified in the Code of violations of the Code; and
• accountability for adherence to the Code.
• Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II. Covered Officers Should Handle Ethically

Actual and Apparent Conflicts of Interest

Overview. A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fidelity Funds. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fidelity Funds.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fidelity Funds and already are subject to conflict of interest provisions in the Investment Company Act of 1940 ("Investment Company Act") and the Investment Advisers Act of 1940 ("Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with a Fidelity Fund because of their status as "affiliated persons" of the Fund. Separate compliance programs and procedures of the Fidelity Funds, Fidelity Management & Research Company ("FMR") and the other Fidelity companies are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fidelity Funds and FMR (or another Fidelity company) of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fidelity Funds, FMR or another Fidelity company), be involved in establishing policies and implementing decisions that have different effects on the Fidelity Funds, FMR and other Fidelity companies. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fidelity Funds and FMR (or another Fidelity company), and is consistent with the performance by the Covered Officers of their duties as officers of the Fidelity Funds. Thus, if performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, such activities will be deemed to have been handled ethically. In addition, it is recognized by the Funds' Board of Trustees ("Board") that the Covered Officers also may be officers or employees of one or more other Fidelity Funds covered by this Code.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of a Fidelity Fund.

* * *

Each Covered Officer must:

• not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting by any Fidelity Fund whereby the Covered Officer would benefit personally to the detriment of any Fidelity Fund;
• not cause a Fidelity Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fidelity Fund;
• not engage in any outside business activity, including serving as a director or trustee, that prevents the Covered Officer from devoting appropriate time and attention to the Covered Officer's responsibilities with the Fidelity Funds;
• not have a consulting or employment relationship with any of the Fidelity Funds' service providers that are not affiliated with Fidelity; and
• not retaliate against any employee or Covered Officer for reports of actual or potential misconduct, which are made in good faith.

With respect to other fact patterns, if a Covered Officer is in doubt, other potential conflict of interest situations should be described immediately to the Fidelity Ethics Office for resolution. Similarly, any questions a Covered Officer has generally regarding the application or interpretation of the Code should be directed to the Fidelity Ethics Office immediately.

III. Disclosure and Compliance

• Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Fidelity Funds.
• Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about any Fidelity Fund to others, whether within or outside Fidelity, including to the Board and auditors, and to governmental regulators and self-regulatory organizations;
• Each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Fidelity Funds, FMR and the Fidelity service providers, and with the Board's Compliance Committee, with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fidelity Funds file with, or submit to, the SEC and in other public communications made by the Fidelity Funds; and
• It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV. Reporting and Accountability

Each Covered Officer must:

• upon receipt of the Code, and annually thereafter, submit to the Fidelity Ethics Office an acknowledgement stating that he or she has received, read, and understands the Code; and
• notify the Fidelity Ethics Office promptly if he or she knows of any violation of the Code. Failure to do so is itself a violation of this Code.

The Fidelity Ethics Office shall take all action it considers appropriate to investigate any actual or potential violations reported to it. Upon completion of the investigation, if necessary, the matter will be reviewed with senior management or other appropriate parties, and a determination will be made as to whether any action should be taken as detailed below. The Covered Officer will be informed of any action determined to be appropriate. The Fidelity Ethics Office will inform the Ethics Oversight Committee of all Code violations and actions taken in response. Without implied limitation, appropriate remedial, disciplinary or preventive action may include a written warning, a letter of censure, suspension, dismissal or, in the event of criminal or other serious violations of law, notification of the SEC or other appropriate law enforcement authorities. Additionally, other legal remedies may be pursued.

The policies and procedures described in the Code do not create any obligations to any person or entity other than the Fidelity Funds. The Code is intended solely for the internal use by the Fidelity Funds and does not constitute a promise, contract or an admission by or on behalf of any Fidelity Fund as to any fact, circumstance, or legal conclusion. The Fidelity Funds, the Fidelity companies and the Fidelity Ethics Officer retain the discretion to decide whether the Code applies to a specific situation, and how it should be interpreted.

V. Oversight

Material violations of this Code will be reported promptly by FMR to the Board's Compliance Committee. In addition, at least once each year, FMR will provide a written report to the Board, which describes any issues arising under the Code since the last report to the Board, including, but not limited to, information about material violations of the Code and action taken in response to the material violations.

VI. Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Fidelity Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Other Fidelity policies or procedures that cover the behavior or activities of Covered Officers are separate requirements applying to the Covered Officers (and others), and are not part of this Code.

VII. Amendments

Any material amendments or changes to this Code must be approved or ratified by a majority vote of the Board, including a majority of the Trustees who are not interested persons of the Fidelity Funds.

VIII. Records and Confidentiality

Records of any violation of the Code and of the actions taken as a result of such violations will be kept by the Fidelity Ethics Office. All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Fidelity Ethics Office, the Ethics Oversight Committee, the Board, appropriate personnel at the relevant Fidelity company or companies and the legal counsel of any or all of the foregoing.
