Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind everyone where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission's forward pricing rules or were involved in so-called "market timing" activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that someone could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner - and in every other. But I underscore again that Fidelity has no so-called "agreements" that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short-term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee - which is returned to the fund and, therefore, to investors - to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over-regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors' holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,

/s/Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including redemption fees, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the 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 (February 1, 2005 to July 31, 2005).

Actual Expenses

The first line of the table below for 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 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.

Hypothetical Example for Comparison Purposes

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

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

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

A Annualized

B Total returns for periods of less than one year are not annualized.

C Total returns would have been lower had certain expenses not been reduced during the periods shown.

D Calculated based on average shares outstanding during the period.

E Expense ratios reflect operating expenses of the fund. Expenses before reductions do not reflect amounts reimbursed by the investment adviser or reductions from brokerage service arrangements or other expense offset arrangements and do not represent the amount paid by the fund during periods when reimbursements or reductions occur. Expenses net of any voluntary waivers reflect expenses after reimbursement by the investment adviser but prior to reductions from brokerage service arrangements or other expense offset arrangements. Expenses net of all reductions represent the net expenses paid by the fund.

F Effective February 1, 2001, the fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and discount on all debt securities. Per-share data and ratios for periods prior to adoption have not been restated to reflect this change.

G Amount represents less than $.001 per share.

1. Significant Accounting Policies.

Fidelity Massachusetts Municipal Income Fund (the income fund), Fidelity Massachusetts AMT Tax-Free Money Market Fund and Fidelity Massachusetts Municipal Money Market Fund (the money market funds) are funds of Fidelity Massachusetts Municipal Trust (the trust). On July 21, 2005, the Board of Trustees approved a change in the names of Spartan Massachusetts Municipal Income Fund and Spartan Massachusetts Municipal Money Market Fund to Fidelity Massachusetts Municipal Income Fund and Fidelity Massachusetts AMT Tax-Free Money Market Fund effective August 15, 2005. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The income fund is a non-diversified fund. Each fund is authorized to issue an unlimited number of shares. Each fund may be affected by economic and political developments in the state of Massachusetts. 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 income fund and the money market funds:

Security Valuation. Net asset value per share (NAV calculation) is calculated as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. For the income fund, debt securities, including restricted securities, are valued on the basis of information provided by a pricing service. Pricing services use valuation matrices that incorporate both dealer-supplied valuations and valuation models. If prices are not readily available or do not accurately reflect fair value for a security, or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value. Price movements in futures contracts and ADRs, market and trading trends, the bid/ask quotes of brokers and off-exchange institutional trading may be reviewed in the course of making a good faith determination of a security's fair value. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued on the basis of amortized cost. Investments in open-end investment companies are valued at their net asset value each business day.

As permitted under Rule 2a-7 of the 1940 Act, and certain conditions therein, securities owned by the money market funds are valued initially at cost and thereafter assume a constant amortization to maturity of any discount or premium.

Investment Transactions and Income. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Interest income is 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.

Income Tax Information and Distributions to Shareholders. Each year, each fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

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 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 futures transactions, prior period premium and discount on debt securities, market discount, deferred trustees compensation and losses deferred due to wash sales and futures transactions.

The funds purchase 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:

Short-Term Trading (Redemption) Fees. Shares held in the income fund less than 30 days are subject to a redemption fee equal to .50% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by Fidelity Management & Research Company (FMR), are retained by the fund and accounted for as an addition to paid in capital.

2. Operating Policies.

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.

Futures Contracts. The income fund may use futures contracts to manage its exposure to the bond market and to fluctuations in interest rates. Buying futures tends to increase a fund's exposure to the underlying instrument, while selling futures tends to decrease a fund's exposure to the underlying instrument or hedge other fund investments. Futures contracts involve, to varying degrees, risk of loss in excess of any futures variation margin reflected in the Statement of Assets and Liabilities. The underlying face amount at value of any open futures contracts at period end is shown in the Schedule of Investments under the caption "Futures Contracts." This amount reflects each contract's exposure to the underlying instrument at period end. Losses may arise from changes in the value of the underlying instruments or if the counterparties do not perform under the contracts' terms. Gains (losses) are realized upon the expiration or closing of the futures contracts. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

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.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and U.S. government securities, for the income fund aggregated $351,986,622 and $286,297,199, respectively.

4. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide Fidelity Massachusetts Municipal Income Fund and Fidelity Massachusetts Municipal Money Market Fund with investment management related services for which the funds pay a monthly management fee. The management fee is the sum of an individual fund fee rate and a group fee rate. The individual fund fee rate is applied to each fund's average net assets. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, each fund's annualized management fee rate expressed as a percentage of each fund's average net assets was as follows:

FMR and its affiliates provide Fidelity Massachusetts AMT Tax-Free Money Market Fund with investment management related services for which the fund pays a monthly management fee that is based on an annual rate of .43% of the fund's average net assets. FMR pays all other expenses, except the compensation of the independent Trustees and certain exceptions such as interest expense. The management fee paid to FMR by the fund is reduced by an amount equal to the fees and expenses paid by the fund to the independent Trustees.

Transfer Agent and Accounting Fees. Citibank, N.A. (Citibank) is the custodian, transfer agent and shareholder servicing agent for the income fund and Fidelity Massachusetts Municipal Money Market Fund. Citibank has entered into a sub-arrangement with Fidelity Service Company, Inc. (FSC), an affiliate of FMR, under which FSC performs the activities associated with the funds' transfer and shareholder servicing agent and accounting functions. The funds pay account fees and asset-based fees that vary

Central Funds. Certain funds may invest in affiliated Central Funds managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR. The Central Funds are open-end investment companies available only to investment companies and other accounts managed by FMR and its affiliates. The Money Market Central Funds seek preservation of capital and current income. The Central Funds do not pay a management fee. Income distributions earned by the funds are recorded as income in the accompanying financial statements. Distributions from the Central Funds are noted in the table below:

5. Committed Line of Credit.

The income fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The participating funds have agreed to pay commitment fees on their pro rata portion of the line of credit. During the period, there were no borrowings on this line of credit.

6. Expense Reductions.

FMR voluntarily agreed to reimburse funds to the extent annual operating expenses exceeded certain levels of average net assets as noted in the table below. Some expenses, for example interest expense, are excluded from this reimbursement.

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

Fidelity Massachusetts Municipal Income Fund (formerly Spartan Massachusetts Municipal Income Fund) / Fidelity Massachusetts AMT Tax-Free Money Market Fund (formerly Spartan Massachusetts Municipal Money Market Fund) / Fidelity Massachusetts Municipal Money Market Fund

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 by Fidelity. At the time of the renewal, the Board had 11 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 during the first six months of each year and as necessary 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 2005 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 (1) the nature, extent, and quality of the services to be provided to each fund and its shareholders by Fidelity (including the investment performance of each fund); (2) the competitiveness of the management fee and total expenses of each fund; (3) 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; (4) the extent to which economies of scale would be realized as each fund grows; and (5) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

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.

Semiannual Report

Nature, Extent, and Quality of Services Provided by Fidelity. 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.

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

Shareholder and Administrative Services. The Board considered the nature, extent, quality, and cost of 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. The Board also considered the nature and extent of the Investment Advisers' supervision of third party service providers, principally custodians and subcustodians. The Board reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers. The Board also considered 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 2004, Fidelity has taken a number of actions that benefited particular funds, including (i) voluntarily deciding in 2004 to stop using "soft" commission dollars to pay for market data and, instead, to pay for that data out of its own resources, (ii) contractually agreeing to impose management fee reductions and expense limitations on its five Spartan stock index funds and its stock index fund available through variable insurance products, (iii) contractually agreeing to eliminate the management fees on the Fidelity Freedom Funds and the Fidelity Advisor Freedom Funds,(iv) contractually agreeing to reduce the management fees on most of its investment-grade taxable bond funds, and (v) contractually agreeing to impose expense limitations on its retail and Spartan investment-grade taxable bond funds.

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, as well as each fund's relative investment performance measured against (i) a broad-based securities market index (bond fund only, as money market funds are typically not compared against a market index), and (ii) 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, 2004, the fund's returns, the returns of a broad-based securities market index ("benchmark") (bond fund only), and a range of returns of a peer group of mutual funds identified by Lipper Inc. as having an investment objective similar to that of the fund. The box within each chart shows the 25th percentile return (bottom of box) and the 75th percentile return (top of box) of the Lipper peer group. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the Lipper peer group whose performance was equal to or lower than that of the fund.

Semiannual Report



The Board noted that the relative investment performance of the fund has compared favorably to its Lipper peer group over time. The Board also noted that the relative investment performance of the fund has compared favorably to its benchmark over time, although the fund's five-year cumulative total return was lower than its benchmark.

The Board noted that the relative investment performance of the fund has compared favorably to its Lipper peer group over time.

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 by Fidelity 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% would mean 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 ("quadrant") in which a fund's management fee ranked, is also included in the charts and considered by the Board. For a more meaningful comparison of management fees, Spartan Massachusetts Municipal Money Market Fund is compared on the basis of a hypothetical "net management fee," which is derived by subtracting payments made by FMR for non-management expenses (including transfer agent fees, pricing and bookkeeping fees, and custody fees) 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.

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 2004. 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 each of Spartan Massachusetts Municipal Income Fund's and Fidelity Massachusetts Municipal Money Market Fund's total expenses, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses.

Semiannual Report

In its review of Spartan Massachusetts Municipal Money Market 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 transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FMR under the all-inclusive arrangement. 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 fund compared to competitive fund median expenses. 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 each fund's total expenses ranked below its competitive median for 2004.

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 each fund's total expenses were reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing 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 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. In addition, a special committee of the Board reviewed services provided to Fidelity by its affiliates and determined that the fees that Fidelity paid for such services were reasonable.

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, including (Spartan Massachusetts Municipal Income Fund and Fidelity Massachusetts Municipal Money Market Fund only) reductions that occur through operation of the transfer agent agreement. The transfer agent fee varies in part based on the number of accounts in a fund. If the number of accounts decreases or the average account size increases, the overall transfer agent fee rate decreases.

The Board recognized that Spartan Massachusetts Municipal Income Fund's and Fidelity Massachusetts Municipal Money Market Fund's management contracts incorporate a "group fee" structure, which provides for lower fee rates as total fund assets under FMR's management increase, and for higher fee rates as total fund assets under FMR's management decrease. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will achieve a certain level of economies of scale as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

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

Semiannual Report

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Advisory Contracts, the Board requested additional information regarding (i) Fidelity's fund profitability methodology, including additional detail on various cost allocations; (ii) fall-out benefits to Fidelity; and (iii) compensation of portfolio managers and research analysts.

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