                                IMPORTANT NOTICE
                              REGARDING DELIVERY OF
                              SHAREHOLDER DOCUMENTS

The Securities and Exchange Commission permits funds to deliver only one copy of
shareholder documents, including prospectuses, proxy statements and shareholder
reports, to fund investors with multiple accounts at the same residential or
post office box address. This practice is often called "householding" and it
helps eliminate duplicate mailings to shareholders.

EATON VANCE, OR YOUR FINANCIAL ADVISER, MAY HOUSEHOLD THE MAILING OF YOUR
DOCUMENTS INDEFINITELY UNLESS YOU INSTRUCT EATON VANCE, OR YOUR FINANCIAL
ADVISER, OTHERWISE.

If you would prefer that your Eaton Vance documents not be householded, please
contact Eaton Vance at 1-800-262-1122, or contact your financial adviser.

Your instructions that householding not apply to delivery of your Eaton Vance
documents will be effective within 30 days of receipt by Eaton Vance or your
financial adviser.

From time to time, funds are required to vote proxies related to the securities
held by the funds. The Eaton Vance Funds or their underlying Portfolios vote
proxies according to a set of policies and procedures approved by the Funds' and
Portfolios' Boards. You may obtain a description of these policies and
procedures without charge, upon request, by calling 1-800-262-1122. This
description is also available on the Securities and Exchange Commission's

EATON VANCE NATIONAL MUNICIPALS FUND as of March 31, 2004

INVESTMENT UPDATE

[PHOTO OF THOMAS M. METZOLD]
Thomas M. Metzold
Portfolio Manager

MANAGEMENT DISCUSSION

- -  Economic activity continued to gain strength in the six months ended March
   31, 2004, although the pace of the recovery was a topic of debate. The
   nation's Gross Domestic Product grew by 4.2% in the first quarter of 2004,
   following a 4.1% rise in the fourth quarter of 2003. While the figures
   suggested a sound overall economy, the slow pace of job creation remained a
   concern.

- -  The investment climate, however, remained generally positive and the bond
   market generated solid returns. The Fund posted strong returns against this
   backdrop, outpacing its benchmark, the Lehman Brothers Municipal Bond Index,
   which had a total return of 3.12% for the six months ended March 31, 2004.*

- -  Escrowed bonds were the Portfolio's largest sector weighting at March 31,
   2004. Pre-refunded and backed by Treasury bonds, escrowed issues provide
   above-average coupons and are deemed very high quality. The second largest
   weighting was industrial development revenue bonds (IDRs). IDRs, particularly
   in the airline sector, provided some compelling opportunities for the
   Portfolio, as the economy began to show signs of improvement and businesses
   increased capital spending, reinvesting in plants and equipment.

FUND PERFORMANCE

   THE PAST SIX MONTHS

- -  During the six months ended March 31, 2004, the Fund's Class A shares had a
   total return of 4.63%.(1) This return resulted from an increase in net asset
   value (NAV) per share to $11.01 on March 31, 2004, from $10.84 on September
   30, 2003, and the reinvestment of $0.328 per share in tax-exempt dividend
   income.(2)

- -  The Fund's Class B shares had a total return of 4.35% during the period,(1)
   the result of an increase in NAV per share to $10.28 from $10.13, and the
   reinvestment of $0.287 per share in tax-exempt dividend income.(2)

- -  The Fund's Class C shares had a total return of 4.23% during the period,(1)
   the result of an increase in NAV per share to $9.79 from $9.64, and the
   reinvestment of $0.255 per share in tax-exempt dividend income.(2)

- -  The Fund's Class I shares had a total return of 4.68% during the period,(1)
   the result of an increase in NAV per share to $10.20 from $10.05, and the
   reinvestment of $0.316 per share in tax-exempt dividend income.(2)

- -  Based on the most recent distributions and NAVs per share on March 31, 2004,
   the distribution rates were 5.95% for Class A, 5.61% for Class B, 5.23% for
   Class C and 6.20% for Class I.(3) The distribution rates of Classes A, B, C
   and I are equivalent to taxable rates of 9.15%, 8.63%, 8.05% and 9.54%,
   respectively.(4)

- -  The SEC 30-day yields at March 31, 2004, were 5.12%, 5.04%, 4.62% and 5.64%
   for Classes A, B, C and I, respectively. (5) These yields are equivalent to
   taxable rates of 7.88%, 7.75%, 7.11% and 8.68%, respectively.(4)

THE VIEWS EXPRESSED THROUGHOUT THIS REPORT ARE THOSE OF THE PORTFOLIO MANAGER
AND ARE CURRENT ONLY THROUGH THE END OF THE PERIOD OF THE REPORT AS STATED ON
THE COVER. THESE VIEWS ARE SUBJECT TO CHANGE AT ANY TIME BASED UPON MARKET OR
OTHER CONDITIONS, AND EATON VANCE DISCLAIMS ANY RESPONSIBILITY TO UPDATE SUCH

+ Inception Dates - Class A: 4/5/94; Class B: 12/19/85; Class C: 12/3/93;

(1)  These returns do not include the 4.75% maximum sales charge for Class A
     shares or the applicable contingent deferred sales charge (CDSC) for Class
     B shares and Class C shares. If the sales charge was deducted, the
     performance would be reduced. Class I shares generally have no sales
     charge. (2) A portion of the Fund's income may be subject to federal income
     tax and/or alternative minimum tax. Income may be subject to state and
     local tax. (3) The Fund's distribution rate represents actual distributions
     paid to shareholders and is calculated daily by dividing the last
     distribution per share (annualized) by the net asset value (NAV). (4)
     Taxable-equivalent rates assume maximum 35.00% federal tax rate. A lower
     rate would result in lower tax-equivalent figures. (5) The Fund's SEC yield
     is calculated by dividing the net investment income per share for the
     30-day period by the offering price at the end of the period and
     annualizing the result. (6) Returns are historical and are calculated by
     determining the percentage change in NAV with all distributions reinvested.
     SEC average annual returns for Class A reflect the maximum sales charge of
     4.75%. Class B returns reflect applicable CDSC based on the following
     schedule: 5% - 1st and 2nd years; 4% - 3rd year; 3% - 4th year; 2% - 5th
     year; 1% - 6th year. For Class C, one year return reflects 1% CDSC.

     Past performance is no guarantee of future results. Investment return and
     principal value may fluctuate so that shares, when redeemed, may be worth
     more or less than their original cost. Yield will vary. Performance is for
     the stated time period only; due to market volatility, the Fund's current
     performance may be lower or higher than the quoted return.


  MUTUAL FUND SHARES ARE NOT INSURED BY THE FDIC AND ARE NOT DEPOSITS OR OTHER
    OBLIGATIONS OF, OR GUARANTEED BY, ANY DEPOSITORY INSTITUTION. SHARES ARE
   SUBJECT TO INVESTMENT RISKS, INCLUDING POSSIBLE LOSS OF PRINCIPAL INVESTED.

(1)  Net investment income per share was computed using average shares
     outstanding.
(2)  The Fund, through its investment in the Portfolio, has adopted the
     provisions of the revised AICPA Audit and Accounting Guide for Investment
     Companies and began using the interest method to amortize premiums on
     fixed-income securities. The effect of this change for the year ended
     September 30, 2002 was to increase net investment income per share by
     $0.003, decrease net realized and unrealized gains per share by $0.003 and
     increase the ratio of net investment income to average net assets from
     6.28% to 6.31%. Per share data and ratios for the periods prior to October
     1, 2001 have not been restated to reflect this change in presentation.
(3)  Returns are historical and are calculated by determining the percentage
     change in net asset value with all distributions reinvested. Total return
     is not computed on an annualized basis.
(4)  Includes the Fund's share of the Portfolio's allocated expenses.
(5)  Annualized.

EATON VANCE NATIONAL MUNICIPALS FUND as of March 31, 2004

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1  SIGNIFICANT ACCOUNTING POLICIES

   Eaton Vance National Municipals Fund (the Fund) is a diversified series of
   Eaton Vance Municipals Trust (the Trust). The Trust is an entity of the type
   commonly known as a Massachusetts business trust and is registered under the
   Investment Company Act of 1940, as amended, as an open-end management
   investment company. The Fund offers four classes of shares. Class A shares
   are generally sold subject to a sales charge imposed at time of purchase.
   Class B and Class C shares are sold at net asset value and are subject to a
   contingent deferred sales charge (see Note 6). The Trustees have adopted a
   conversion feature pursuant to which Class B shares of the Fund automatically
   convert to Class A shares eight years after their purchase as described in
   the Fund's prospectus. In addition, all Class B shares of the Fund purchased
   on or before March 16, 2004 converted to Class A shares of the same Fund on
   April 8, 2004. Class I shares are sold at net asset value to certain
   institutional investors. Each class represents a pro rata interest in the
   Fund, but votes separately on class-specific matters and (as noted below) is
   subject to different expenses. Realized and unrealized gains and losses are
   allocated daily to each class of shares based on the relative net assets of
   each class to the total net assets of the Fund. Net investment income, other
   than class-specific expenses, is allocated daily to each class of shares
   based upon the ratio of the value of each class' paid shares to the total
   value of all paid shares. Each class of shares differs in its distribution
   plan and certain other class-specific expenses. The Fund invests all of its
   investable assets in interests in National Municipals Portfolio (the
   Portfolio), a New York Trust, having the same investment objective as the
   Fund. The value of the Fund's investment in the Portfolio reflects the Fund's
   proportionate interest in the net assets of the Portfolio (99.9% at March 31,
   2004). The performance of the Fund is directly affected by the performance of
   the Portfolio. The financial statements of the Portfolio, including the
   portfolio of investments, are included elsewhere in this report and should be
   read in conjunction with the Fund's financial statements.

   The following is a summary of significant accounting policies consistently
   followed by the Fund in the preparation of its financial statements. The
   policies are in conformity with accounting principles generally accepted in
   the United States of America.

   A INVESTMENT VALUATION -- Valuation of securities by the Portfolio is
   discussed in Note 1A of the Portfolio's Notes to Financial Statements which
   are included elsewhere in this report.

   B INCOME -- The Fund's net investment income consists of the Fund's pro rata
   share of the net investment income of the Portfolio, less all actual and
   accrued expenses of the Fund determined in accordance with accounting
   principles generally accepted in the United States of America.

   C FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
   Internal Revenue Code applicable to regulated investment companies and to
   distribute to shareholders each year all of its taxable, if any, and
   tax-exempt income, including any net realized gain on investments.
   Accordingly, no provision for federal income or excise tax is necessary. At
   September 30, 2003, the Fund, for federal income tax purposes, had a capital
   loss carryover of $23,042,053 which will reduce the taxable income arising
   from future net realized gains on investments, if any, to the extent
   permitted by the Internal Revenue Code, and thus will reduce the amount of
   the distributions to shareholders which would otherwise be necessary to
   relieve the Fund of any liability for federal income or excise tax. A portion
   of such capital loss carryover was acquired through a Fund Reorganization and
   may be subject to certain limitations. Such capital loss carryover will
   expire on September 30, 2009. Dividends paid by the Fund from net tax-exempt
   interest on municipal bonds allocated from the Portfolio are not includable
   by shareholders as gross income for federal income tax purposes because the
   Fund and Portfolio intend to meet certain requirements of the Internal
   Revenue Code applicable to regulated investment companies which will enable
   the Fund to pay exempt-interest dividends. The portion of such interest, if
   any, earned on private activity bonds issued after August 7, 1986, may be
   considered a tax preference item to shareholders.

   Additionally, at September 30, 2003, the Fund had net capital losses of
   $8,653,345 attributable to security transactions incurred after October 31,
   2002. These capital losses are treated as arising on the first day of the
   Fund's current taxable year.

   D USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America requires management to make estimates and assumptions that affect
   the reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

   E INDEMNIFICATIONS -- Under the Trust's organizational documents, its
   officers and Trustees may be indemnified against certain liabilities and
   expenses arising

                                        9
<Page>

   out of the performance of their duties to the Fund, and shareholders are
   indemnified against personal liability for obligations of the Trust.
   Additionally, in the normal course of business, the Fund enters into
   agreements with service providers that may contain indemnification clauses.
   The Fund's maximum exposure under these arrangements is unknown as this would
   involve future claims that may be made against the Fund that have not yet
   occurred.

   F EXPENSES -- The majority of expenses of the Trust are directly identifiable
   to an individual fund. Expenses which are not readily identifiable to a
   specific fund are allocated taking into consideration, among other things,
   the nature and type of expense and the relative size of the funds.

   G OTHER -- Investment transactions are accounted for on a trade-date basis.

   H EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
   custodian to the Fund and the Portfolio. Pursuant to the respective custodian
   agreements, IBT receives a fee reduced by credits which are determined based
   on the average daily cash balances the Fund or the Portfolio maintains with
   IBT. All significant credit balances used to reduce the Fund's custodian fees
   are reported as a reduction of total expenses in the Statement of Operations.

   I INTERIM FINANCIAL STATEMENTS -- The interim financial statements relating
   to March 31, 2004 and for the six months then ended have not been audited by
   independent certified public accountants, but in the opinion of the Fund's
   management reflect all adjustments, consisting only of normal recurring
   adjustments, necessary for the fair presentation of the financial statements.

2  DISTRIBUTIONS TO SHAREHOLDERS

   The net income of the Fund is determined daily and substantially all of the
   net income so determined is declared as a dividend to shareholders of record
   at the time of declaration. Distributions are declared separately for each
   class of shares. Distributions are paid monthly. Distributions of allocated
   realized gains, if any, are made at least annually. Shareholders may reinvest
   capital gain distributions in additional shares of the same class of the Fund
   at the net asset value as of the ex-dividend date. Distributions are paid in
   the form of additional shares of the same class or, at the election of the
   shareholder, in cash. The Fund distinguishes between distributions on a tax
   basis and a financial reporting basis. Accounting principles generally
   accepted in the United States of America require that only distributions in
   excess of tax basis earnings and profits be reported in the financial
   statements as a return of capital. Permanent differences between book and tax
   accounting relating to distributions are reclassified to paid-in capital.

3  SHARES OF BENEFICIAL INTEREST

   The Fund's Declaration of Trust permits the Trustees to issue an unlimited
   number of full and fractional shares of beneficial interest (without par
   value). Such shares may be issued in a number of different series (such as
   the Fund) and classes. Transactions in Fund shares were as follows:

4  INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

   Eaton Vance Management (EVM) serves as the Administrator of the Fund, but
   receives no compensation. The Portfolio has engaged Boston Management and
   Research (BMR), a subsidiary of EVM, to render investment advisory services.
   See Note 2 of the Portfolio's Notes to Financial Statements which are
   included elsewhere in this report. Except as to Trustees of the Fund and the
   Portfolio who are not members of EVM's or BMR's organization, officers and
   Trustees receive remuneration for their services to the Fund out of the
   investment adviser fee earned by BMR. EVM serves as the sub-transfer agent of
   the Fund and receives from the transfer agent an aggregate fee based upon the
   actual expenses incurred by EVM in the performance of those services. For the
   six months ended March 31, 2004, EVM earned $33,427 in sub-transfer agent
   fees. The Fund was informed that Eaton Vance Distributors, Inc. (EVD), a
   subsidiary of EVM and the Fund's principal underwriter, received $68,456 as
   its portion of the sales charge on sales of Class A shares for the six months
   ended March 31, 2004.

   Certain officers and Trustees of the Fund and of the Portfolio are officers
   of the above organizations.

5  DISTRIBUTION AND SERVICE PLANS

   The Fund has in effect distribution plans for Class B shares (Class B Plan)
   and Class C shares (Class C Plan) pursuant to Rule 12b-1 under the Investment
   Company Act of 1940 and a service plan for Class A shares (Class A Plan),
   (collectively, the Plans). The Class B and Class C Plans require the Fund to
   pay EVD amounts equal to 1/365 of 0.75% of the Fund's average daily net
   assets attributable to Class B and Class C shares for providing ongoing
   distribution services and facilities to the Fund. The Fund will automatically
   discontinue payments to EVD during any period in which there are no
   outstanding Uncovered Distribution Charges, which are equivalent to the sum
   of (i) 5% and 6.25% of the aggregate amount received by the Fund for the
   Class B and Class C shares sold, respectively, plus (ii) interest calculated
   by applying the rate of 1% over the prevailing prime rate to the outstanding
   balance of Uncovered Distribution Charges of EVD of each respective class
   reduced by the aggregate amount of contingent deferred sales charges (see
   Note 6) and daily amounts theretofore paid to EVD by each respective class.
   The Fund paid or accrued $3,150,551 and $792,987 for Class B, and Class C
   shares, respectively, payable to EVD for the six months ended March 31, 2004,
   representing 0.40% and 0.75% (annualized) of the average daily net assets for
   Class B and Class C shares, respectively. At March 31, 2004, the amount of
   Uncovered Distribution Charges EVD calculated under the Plans was
   approximately $70,000 and $27,595,000 for Class B and Class C shares.

   The Plans authorize the Fund to make payments of service fees to EVD,
   investment dealers and other persons in amounts not exceeding 0.25%
   (annualized) of the Fund's average daily net assets attributable to Class A,
   Class B, and Class C shares for each fiscal year. Service fee payments will
   be made for personal services and/or the maintenance of shareholder accounts.
   Service fees are separate and distinct from the sales commissions and
   distribution fees payable by the Fund to EVD, and, as such are not subject to
   automatic discontinuance when there are no outstanding Uncovered Distribution
   Charges of EVD. Service fee payments for the six months ended March 31, 2004
   amounted to $321,984, $1,963,619, and $264,329 for Class A, Class B, and
   Class C shares, respectively.

6  CONTINGENT DEFERRED SALES CHARGE

   A contingent deferred sales charge (CDSC) generally is imposed on redemptions
   of Class B shares made within six years of purchase and on redemptions of
   Class C shares made within one year of purchase. Generally, the CDSC is based
   upon the lower of the net asset value at date of redemption or date of
   purchase. No charge is levied on shares acquired by reinvestment of dividends
   or capital gains distributions. Class B CDSC is imposed at declining rates
   that begin at 5% in the case of redemptions in the first and second year
   after purchase, declining one percentage point each subsequent year. Class C
   shares will be subject to a 1% CDSC if redeemed within one year of purchase.
   No CDSC is levied on shares which have been sold to EVM or its affiliates or
   to their respective employees or clients and may be waived under certain
   other limited conditions. CDSC charges are paid to EVD to reduce the amount
   of Uncovered Distribution Charges calculated under each Fund's Distribution
   Plan (see Note 5). CDSC charges received when no Uncovered Distribution
   Charges exist will be credited to the Fund. EVD received approximately

                                       11
<Page>

   $25,000 of CDSC paid by shareholders for Class C shares for the six months
   ended March 31, 2004. EVD also received approximately $406,000 of CDSC paid
   by Class B shareholders of which $317,066 was paid directly to the Fund for
   days when no Uncovered Distribution Charges existed.

   Portfolio aggregated $178,159,269 and $174,898,282, respectively, for the six

The Portfolio invests primarily in debt securities issued by municipalities. The
ability of the issuers of the debt securities to meet their obligations may be
affected by economic developments in a specific industry or municipality. In
order to reduce the risk associated with such economic developments, at March
31, 2004, 28.7% of the securities in the portfolio of investments are backed by
bond insurance of various financial institutions and financial guaranty
assurance agencies. The aggregate percentage insured by an individual financial
institution ranged from 0.9% to 8.7% of total investments.

(1)  Security has been issued as a leveraged inverse floater bond.

(2)  Security has been issued as an inverse floater bond.

(3)  Security exempt from registration under Rule 144A of the Securities Act of
     1933. These securities may be resold in transactions exempt from
     registration, normally to qualified institutional buyers.

(4)  Non-income producing security.

(5)  Security (or a portion thereof) has been segregated to cover margin
     requirements on open financial futures contracts.

(6)  The Portfolio is accruing only partial interest on this security.

NATIONAL MUNICIPALS PORTFOLIO as of March 31, 2004

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1  SIGNIFICANT ACCOUNTING POLICIES

   National Municipals Portfolio (the Portfolio) is registered under the
   Investment Company Act of 1940, as amended, as a diversified open-end
   management investment company which was organized as a trust under the laws
   of the State of New York on May 1, 1992. The Declaration of Trust permits the
   Trustees to issue interests in the Portfolio. At March 31, 2004, Eaton Vance
   National Municipals Fund held an approximate 99.9% interest in the Portfolio.
   The following is a summary of significant accounting policies of the
   Portfolio. The policies are in conformity with accounting principles
   generally accepted in the United States of America.

   A INVESTMENT VALUATION -- Municipal bonds are normally valued on the basis of
   valuations furnished by a pricing service. Taxable obligations, if any, for
   which price quotations are readily available are normally valued at the mean
   between the latest bid and asked prices. Futures contracts listed on the
   commodity exchanges are valued at closing settlement prices. Short-term
   obligations, maturing in sixty days or less, are valued at amortized cost,
   which approximates value. Interest rate swaps are normally valued on the
   basis of calculations furnished by a broker. Investments for which valuations
   or market quotations are unavailable are valued at fair value using methods
   determined in good faith by or at the direction of the Trustees.

   B INCOME -- Interest income is determined on the basis of interest accrued,
   adjusted for amortization of premium and discount.

   C FEDERAL TAXES -- The Portfolio is treated as a partnership for federal tax
   purposes. No provision is made by the Portfolio for federal or state taxes on
   any taxable income of the Portfolio because each investor in the Portfolio is
   ultimately responsible for the payment of any taxes. Since some of the
   Portfolio's investors are regulated investment companies that invest all or
   substantially all of their assets in the Portfolio, the Portfolio normally
   must satisfy the applicable source of income and diversification requirements
   (under the Internal Revenue Code) in order for its investors to satisfy them.
   The Portfolio will allocate at least annually among its investors each
   investor's distributive share of the Portfolio's net taxable (if any) and
   tax-exempt investment income, net realized capital gains, and any other items
   of income, gain, loss, deduction or credit. Interest income received by the
   Portfolio on investments in municipal bonds, which is excludable from gross
   income under the Internal Revenue Code, will retain its status as income
   exempt from federal income tax when allocated to the Portfolio's investors.
   The portion of such interest, if any, earned on private activity bonds issued
   after August 7, 1986 may be considered a tax preference item for investors.

   D FINANCIAL FUTURES CONTRACTS -- Upon the entering of a financial futures
   contract, the Portfolio is required to deposit (initial margin) either in
   cash or securities an amount equal to a certain percentage of the purchase
   price indicated in the financial futures contract. Subsequent payments are
   made or received by the Portfolio (margin maintenance) each day, dependent on
   the daily fluctuations in the value of the underlying security, and are
   recorded for book purposes as unrealized gains or losses by the Portfolio.
   The Portfolio's investment in financial futures contracts is designed for
   both hedging against anticipated future changes in interest rates and
   investment purposes. Should interest rates move unexpectedly, the Portfolio
   may not achieve the anticipated benefits of the financial futures contracts
   and may realize a loss.

   E INTEREST RATE SWAPS -- The Portfolio may enter into interest rate swap
   agreements to enhance return, to hedge against fluctuations in securities
   prices or interest rates or as substitution for the purchase or sale of
   securities. Pursuant to the agreement, the Portfolio makes bi-annual payments
   at a fixed interest rate. In exchange, a Portfolio receives payments based on
   the interest rate of a benchmark industry index. During the term of the
   outstanding swap agreement, changes in the underlying value of the swap are
   recorded as unrealized gains and losses. The value of the swap is determined
   by changes in the relationship between two rates of interest. The Portfolio
   is exposed to credit loss in the event of non-performance by the swap
   counterparty. However, the Portfolio does not anticipate non-performance by
   the counterparty. Risk may also rise from the unanticipated movements in
   value of interest rates.

   F OPTIONS ON FINANCIAL FUTURES CONTRACTS -- Upon the purchase of a put option
   on a financial futures contract by the Portfolio, the premium paid is
   recorded as an investment, the value of which is marked-to-market daily. When
   a purchased option expires, the Portfolio will realize a loss in the amount
   of the cost of the option. When the Portfolio enters into a closing sale
   transaction, the Portfolio will realize a gain or loss depending on whether
   the sales proceeds from the closing sale transaction are greater or less than
   the cost of the option. When the Portfolio exercises a put option, settlement
   is made in cash. The risk associated with purchasing put options is limited
   to the premium originally paid.

                                       22
<Page>

   G LEGAL FEES -- Legal fees and other related expenses incurred as part of
   negotiations of the terms and requirements of capital infusions, or that are
   expected to result in the restructuring of or a plan of reorganization for an
   investment are recorded as realized losses. Ongoing expenditures to protect
   or enhance an investment are treated as operating expenses.

   H WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS -- The Portfolio may engage
   in when-issued and delayed delivery transactions. The Portfolio records
   when-issued securities on trade date and maintains security positions such
   that sufficient liquid assets will be available to make payments for the
   securities purchased. Securities purchased on a when-issued or delayed
   delivery basis are marked-to-market daily and begin earning interest on
   settlement date.

   I USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America requires management to make estimates and assumptions that affect
   the reported amounts of assets and liabilities at the date of the financial
   statements and the reported amounts of income and expense during the
   reporting period. Actual results could differ from those estimates.

   J INDEMNIFICATIONS -- Under the Portfolio's organizational documents, its
   officers and Trustees may be indemnified against certain liabilities and
   expenses arising out of the performance of their duties to the Portfolio.
   Interestholders in the Portfolio are jointly and severally liable for the
   liabilities and obligations of the Portfolio in the event that the Portfolio
   fails to satisfy such liabilities and obligations; provided, however, that,
   to the extent assets are available in the Portfolio, the Portfolio may, under
   certain circumstances, indemnify interestholders from and against any claim
   or liability to which such holder may become subject by reason of being or
   having been an interestholder in the Portfolio. Additionally, in the normal
   course of business, the Portfolio enters into agreements with service
   providers that may contain indemnification clauses. The Portfolio's maximum
   exposure under these arrangements is unknown as this would involve future
   claims that may be made against the Portfolio that have not yet occurred.

   K OTHER -- Investment transactions are accounted for on a trade date basis.
   Realized gains and losses are computed based on the specific identification
   of the securities sold.

   L EXPENSE REDUCTIONS -- Investors Bank & Trust Company (IBT) serves as
   custodian of the Portfolio. Pursuant to the custodian agreement, IBT receives
   a fee reduced by credits which are determined based on the average daily cash
   balance the Portfolio maintains with IBT. All significant credit balances
   used to reduce the Portfolio's custodian fees are reported as a reduction of
   total expenses on the Statement of Operations.

   M INTERIM FINANCIAL STATEMENTS -- The interim financial statements relating
   to March 31, 2004 and for the six months then ended have not been audited by
   independent certified public accountants, but in the opinion of the Fund's
   management reflect all adjustments, consisting only of normal recurring
   adjustments, necessary for the fair presentation of the financial statements.

2  INVESTMENT ADVISER FEE AND OTHER TRANSACTIONS WITH AFFILIATES

   The investment adviser fee is earned by Boston Management and Research (BMR),
   a wholly-owned subsidiary of Eaton Vance Management (EVM), as compensation
   for management and investment advisory services rendered to the Portfolio.
   The fee is based upon a percentage of average daily net assets plus a
   percentage of gross income (i.e., income other than gains from the sale of
   securities). For the six months ended March 31, 2004, the fee was equivalent
   to 0.43% of the Portfolio's average daily net assets for such period and
   amounted to $4,429,923. Except as to Trustees of the Portfolio who are not
   members of EVM's or BMR's organization, officers and Trustees receive
   remuneration for their services to the Portfolio out of such investment
   adviser fee. Trustees of the Portfolio that are not affiliated with the
   Investment Adviser may elect to defer receipt of all or a percentage of their
   annual fees in accordance with the terms of the Trustees Deferred
   Compensation Plan. For the six months ended March 31, 2004, no significant
   amounts have been deferred.

   Certain officers and Trustees of the Portfolio are officers of the above
   organizations.

3  INVESTMENTS

   Purchases and sales of investments, other than U.S. Government securities and
   short-term obligations, aggregated $541,977,545 and $535,837,491,
   respectively, for the six months ended March 31, 2004.

4  FEDERAL INCOME TAX BASIS OF UNREALIZED APPRECIATION (DEPRECIATION)

   The cost and unrealized appreciation/depreciation in the value of the
   investments owned at March 31, 2004, as computed on a federal income tax
   basis, were as follows:

   AGGREGATE COST                                   $  1,884,960,898
   -----------------------------------------------------------------
   Gross unrealized appreciation                    $    248,394,751
   Gross unrealized depreciation                         (63,927,357)
   -----------------------------------------------------------------
   NET UNREALIZED APPRECIATION                      $    184,467,394
   -----------------------------------------------------------------
</Table>

5  LINE OF CREDIT

   The Portfolio participates with other portfolios and funds managed by BMR and
   EVM and its affiliates in a $150 million unsecured line of credit agreement
   with a group of banks. The Portfolio may temporarily borrow from the line of
   credit to satisfy redemption requests or settle investment transactions.
   Interest is charged to each portfolio or fund based on its borrowings at an
   amount above either the Eurodollar rate or federal funds rate. In addition, a
   fee computed at an annual rate of 0.10% on the daily unused portion of the
   line of credit is allocated among the participating portfolios and funds at
   the end of each quarter. The Portfolio did not have any significant
   borrowings or allocated fees during the six months ended March 31, 2004.

6  FINANCIAL INSTRUMENTS

   The Portfolio regularly trades in financial instruments with off-balance
   sheet risk in the normal course of its investing activities to assist in
   managing exposure to various market risks. These financial instruments
   include futures contracts and interest rate swap contracts and may involve,
   to a varying degree, elements of risk in excess of the amounts recognized for
   financial statement purposes.

   The notional or contractual amounts of these instruments represent the
   investment a Portfolio has in particular classes of financial instruments and
   does not necessarily represent the amounts potentially subject to risk. The
   measurement of the risks associated with these instruments is meaningful only
   when all related and offsetting transactions are considered.

   --------------------------------------------------------------------
</Table>

   At March 31, 2004, the Portfolio had entered into an interest rate swap
   agreement with Morgan Stanley Capital Services and two interest rate swap
   agreements with Merrill Lynch Capital Services. The Portfolio makes payments
   at rates equal to 4.315%, 4.750% and 4.355% biannually on the notional
   amounts of $100,000,000, $125,000,000 and $170,000,000, respectively. In
   exchange, the Portfolio receives payments at a rate equal to the Bond Market
   Association Municipal Swap Index on the same notional amounts. The value of
   the contracts, that terminate on June 9, 2024, August 11, 2014, and September
   23, 2014 of ($3,037,952), ($3,405,685) and $1,724,488, respectively, are
   recorded as an aggregate payable for open swap contracts of $4,719,149 on
   March 31, 2004.
