Shareholder Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds 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 (April 1, 2007 to September 30, 2007).

Actual Expenses

The first line of the accompanying table for each class of each fund 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 for a class of the fund 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, each 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 for each class of each fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' 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, each 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.

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.

For the period ended September 30, 2007 (Unaudited)

(Amounts in thousands except ratios)

1. Organization.

Treasury Only Portfolio, Treasury Portfolio, Government Portfolio, Prime Money Market Portfolio, Money Market Portfolio and Tax-Exempt Portfolio (the Funds) are funds of Fidelity Colchester Street Trust (the trust). Each Fund 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.

Each Fund offers Class I, Class II, and Class III and Select Class shares, each of which has equal rights as to assets and voting privileges. On September 20, 2007, the Board of Trustees approved the creation of additional classes of shares for Treasury Only Portfolio, Treasury Portfolio, Prime Money Market Portfolio and Money Market Portfolio. Money Market Portfolio and Prime Money Market Portfolio are expected to commence sale of shares of Institutional Class on or about December 12, 2007. In addition, Prime Money Market Portfolio, Treasury Portfolio and Treasury Only Portfolio are expected to commence sale of shares of Class IV on or about December 12, 2007. After commencement of the Institutional Class shares, Prime Money Market Portfolio and Money Market Portfolio will begin offering conversion privileges between classes within each fund to eligible shareholders of the existing classes of shares. Each class has exclusive voting rights with respect to matters that affect that class. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of each Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class.

2. Investments in Fidelity Central Funds.

The Funds may invest in Fidelity Central Funds, which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Funds' Schedules of Investments list each of the Fidelity Central Funds as an investment of each Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Funds indirectly bear their 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 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 Funds:

Security Valuation. As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates value. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day.

Investment Transactions and Income. Security transactions, including the Funds' investment activity in the Fidelity Central Funds, are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and income and capital gain 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.

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.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan) for Government Portfolio and Money Market Portfolio, Independent Trustees must defer receipt of a portion of, and may elect to defer receipt of an additional portion of, their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees are included in the accompanying Statement of Assets and Liabilities.

Income Tax Information and Distributions to Shareholders.Each Fund intends to qualify as a regulated investment company by 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. Each Fund adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainties in Income Taxes (FIN 48), on June 29, 2007. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. Each of the tax years in the three year period ended June 29, 2007 remains subject to examination by the Internal Revenue Service.

Semiannual Report

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders - continued

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, certain Funds claimed 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 deferred trustees compensation, capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

The Tax-Exempt Portfolio purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows for each Fund:

	Cost for Federal Income Tax Purposes	Unrealized Appreciation	Unrealized Depreciation	Net Unrealized Appreciation/ (Depreciation)
Treasury Only Portfolio	$ 2,457,058	$ -	$ -	$ -
Treasury Portfolio	19,568,255	-	-	-
Government Portfolio	10,641,541	-	-	-
Prime Money Market Portfolio	14,659,532	-	-	-
Money Market Portfolio	35,791,627	-	-	-
Tax-Exempt Portfolio	11,527,809	-	-	-

New Accounting Pronouncement. 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 Funds' financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits certain Funds and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. Certain Funds 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. Each applicable 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.

Delayed Delivery Transactions and When-Issued Securities. Certain Funds may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in each applicable Fund's Schedule of Investments. Certain Funds may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, each applicable Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. Certain Funds may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of each applicable Fund's Schedule of Investments.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Funds with investment management related services for which the Funds pay a monthly management fee that is based on an annual rate of .20% of average net assets.

On November 15, 2007, the Board of Trustees approved an amendment to the Funds' management contract. Under the amended management contract, effective December 1, 2007, the management fee rate will be lowered from .20% to .14% of average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Funds have adopted separate Distribution and Service Plans for Class II, Class III and Select Class shares. Class II, Class III and Select Class of each Fund pays Fidelity Distributors Corporation (FDC), an affiliate of FMR, a Service fee based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Funds and providing shareholder support services. For the period, the Service fee rates were as follows:

Interfund Lending Program. Pursuant to an Exemptive Order issued by the SEC, the Funds, along with other registered investment companies having management contracts with FMR, may participate in an interfund lending program.

7. Other.

The Funds' 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 Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

FIMM Funds: Treasury Only Portfolio / Treasury Portfolio / Government Portfolio / Prime Money Market Portfolio / Money Market Portfolio / Tax-Exempt Portfolio

Each year, typically in June, 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 each 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 each fund's Advisory Contracts, including the services and support provided to each 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 Fixed-Income 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.

At its June 2007 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the Advisory Contracts for each 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 each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness of the management fee and total expenses of each 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 each fund; (iv) the extent to which economies of scale would be realized as each 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 each 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 each 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 contracts 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 each 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 each 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 that 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 backgrounds of the funds' portfolio managers and the funds' investment objectives and disciplines. 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.

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. In addition, the Board considered the trading resources that are an integrated part of the fixed-income portfolio management investment process.

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 and pricing and bookkeeping services for each 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, each fund's compliance policies and procedures.

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 a 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 June 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. The Board considered whether each fund has operated within its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed each fund's absolute investment performance for each class, as well as each fund's relative investment performance for each class measured against a peer group of mutual funds deemed appropriate by the Board over multiple periods. For each fund, the following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2006, the cumulative total returns of Class I and Class III of the fund, and a range of cumulative total returns of a peer group of mutual funds identified by Lipper Inc. as having an investment objective similar to that of the fund. The returns of Class I and Class III show the performance of the highest and lowest performing classes, respectively (based on three-year performance). 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 numbers noted below each chart correspond to the percentile box and represent the percentage of funds in the peer group whose performance was equal to or lower than that of the class indicated.

Treasury Only Portfolio

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of Class I of the fund was in the second quartile for the one-year period and the first quartile for the three- and five-year periods. The Board considered that the variations in performance among the fund's classes reflect the variations in class expenses, which result in lower performance for higher expense classes.

Semiannual Report

Treasury Portfolio

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of Class I of the fund was in the first quartile for all the periods shown. The Board considered that the variations in performance among the fund's classes reflect the variations in class expenses, which result in lower performance for higher expense classes.

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of Class I of the fund was in the first quartile for all the periods shown. The Board considered that the variations in performance among each fund's classes reflect the variations in class expenses, which result in lower performance for higher expense classes.

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 each fund will benefit each fund's shareholders, particularly in light of the Board's view that each 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 each 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 considered two proprietary management fee comparisons for the 12-month periods shown in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group" and, for the reasons explained above, is broader than the Lipper peer group used by the Board for performance comparisons. 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 a fund's. For example, a TMG % of 24% means that 76% of the funds in the Total Mapped Group had higher management fees than a 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 a fund's management fee ranked, is also included in the charts and considered by the Board.

The Board noted that each 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 each fund's management fee was fair and reasonable in light of the services that the fund receives and the other factors considered.

In its review of the total expenses of each class of each fund, the Board considered the fund's management fee as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, fund-paid 12b-1 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 each class of each fund compared to competitive fund median expenses. Each class of each 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 total expenses of Class I, Class II, and Select Class of each fund ranked below its competitive median for 2006, and the total expenses of Class III of each fund ranked above its competitive median for 2006. The Board noted that each fund offers multiple classes, each of which has a different 12b-1 fee structure, and that the multiple structures are intended to offer a range of pricing options for the intermediary market. The Board also noted that the total expenses of the classes vary primarily by the level of their 12b-1 fees.

Semiannual Report

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 total expenses of each class of each fund were reasonable, although in some cases above the median of the universe presented for comparison, 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 each 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 each 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.

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 funds' business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of each fund and determined that the amount of profit is a fair entrepreneurial profit for the management of each 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 each 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 each fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board 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) Fidelity's fund profitability methodology, profitability by investment discipline, and profitability trends within certain funds; (ii) Fidelity's compensation structure relative to competitors and its effect on profitability; (iii) funds and accounts managed by Fidelity other than the Fidelity funds, including fee arrangements; (iv) the total expenses of certain funds and classes relative to competitors; (v) fund performance trends; (vi) fall-out benefits received by certain Fidelity affiliates; and (vii) Fidelity's fee structures.

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 each fund's Advisory Contracts should be renewed.
