Investment Environment
- --------------------------------------------------------------------------------

   The Economy

 .  The U.S. economy in the second half of 1996 was favorable for the bond
   markets, as continued moderate growth and low inflation combined with a
   reduced federal budget deficit. Against this back-drop, bond yields finished
   the year lower than at mid-year.

 .  The first quarter of 1997 has been marked by stronger-than-expected economic
   growth, a tightening labor market, and increasing uneasiness over inflation,
   which remains low. First quarter Gross Domestic Product (GDP) grew at a
   remarkably fast annual rate of 5.6%, the strongest quarterly growth in over a
   decade.

 .  Consumer spending surged 6.4% in the first quarter of 1997, aided by rising
   employment and a milder-than-normal winter in some parts of the nation.
   Consumer spending had increased by 3.4% in the final quarter of 1996.

   The Bond Market

 .  At its March 25 meeting, the Federal Reserve raised the Federal Funds Target
   Rate 0.25% in an effort to slow the economy and make a preemptory strike at
   inflation.

 .  In response to 1997's economic events and the increase in short-term interest
   rates, the bond market has sold off somewhat. The yield on the 30-year
   Treasury Bond - a widely held gauge of bond market sentiment - rose to 7.08%
   on March 31 from 6.64% at the end of 1996. Despite a subsequent rally in bond
   prices since March 31, investors remain concerned about further rate hikes by
   the Federal Reserve.

 .  During the past six months, the municipal bond market has outperformed the
   Treasury market. As discussion of the flat-tax faded from the political
   agenda in 1996, investors focused on the excellent values that tax-exempt
   bonds represent.

The Fund
- --------------------------------------------------------------------------------

   The Past Six Months

 .  During the six months ended March 31, 1997, the Fund had a total return of
   2.2%./1/

 .  This return resulted from a decrease in net asset value per share to $9.84 on
   March 31, 1997 from $9.90 on September 30, 1996, and the reinvestment of
   $0.276 per share in tax-free income dividends./2/

 .  Based on the Fund's most recent dividend, and a net asset value of $9.48 per
   share, the Fund's distribution rate on March 31, 1997 was 5.64%.

 .  To equal 5.64% in a taxable investment, a couple in the 36% combined federal
   and state tax bracket would need a yield of 8.81%. 

   Management Discussion

 .  The Fund has benefited from investments in a wide range of projects and
   special situations, producing higher-than-average yields while maintaining
   strong underlying fundamentals. In a difficult interest rate environment,
   these bonds generally held their values well while continuing to pay high 
   tax-exempt income.

 .  Unlike the broader market, which is typically sensitive to interest rate
   movements, this Fund's holdings tend to be more credit-driven. As a result,
   their performance is more dependent on the fundamentals and financial
   strength of the underlying projects that secure the bonds.

 .  The Fund remains well-diversified, with strength in the industrial
   development, health care, and transportation sectors.

/(1)/  Total return is calculated assuming a purchase at the net asset value on
       the first day and a sale at the net asset value on the last day of each
       period reported. Dividends and distributions, if any, are assumed to be
       reinvested at the net asset value on the payable date. Total return is
       not computed on an annualized basis.

/(2)/  Includes the Fund's share of its corresponding Portfolio's allocated
       expenses.

/(3)/  The expense ratios for the year ended September 30, 1995 and periods
       thereafter, have been adjusted to reflect a change in reporting
       requirements. The new reporting guidelines require the Fund, as well as
       its corresponding Portfolio, to increase its expense ratio by the effect
       of any expense offset arrangements with its service providers. The
       expense ratios for the prior periods have not been adjusted to reflect
       this change.

/(4)/  Portfolio Turnover represents the rate of portfolio activity for the
       period while the Fund was making investments directly in securities. The
       portfolio turnover rate for the period since the Fund transferred
       substantially all of its investable assets to the Portfolio is shown in
       the Portfolio's financial statements which are included elsewhere in this
       report.

EV Marathon National Municipals Fund as of March 31, 1997

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D



1    Significant Accounting Policies
     ---------------------------------------------------------------------------
     EV Marathon 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 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 (94.8% at March 31, 1997). 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 generally accepted accounting principles.

     A Investment Valuations -- 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 generally
     accepted accounting principles.

     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 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, 1996, the Fund, for federal income tax purposes had a capital
     loss carryover of $93,534,883 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. Such
     capital loss carryover will expire on September 30, 2003 ($8,244,733) and
     September 30, 2004 ($85,290,150). Additionally, at September 30, 1996, net
     capital losses of $5,556,597 attributable to security transactions incurred
     after October 31, 1995, are treated as arising on the first day of the
     Fund's current taxable year. 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.

     D Use of Estimates -- The preparation of financial statements in conformity
     with generally accepted accounting principles 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 revenue and expense during the reporting period. Actual results
     could differ from those estimates.

     E Other -- Investment transactions are accounted for on a trade-date basis.

     F 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 expenses on
     the statement of operations.

     G Interim Financial Information -- The interim financial statements
     relating to March 31, 1997 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 paid monthly.

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D




     Distributions of allocated realized gains, if any, are made at least
     annually. Shareholders may reinvest capital gain distributions in
     additional shares of the Fund at the net asset value as of the ex-dividend
     date. Distributions are paid in the form of additional shares or, at the
     election of the shareholder, in cash. The Fund distinguishes between
     distributions on a tax basis and a financial reporting basis. Generally
     accepted accounting principles require that only distributions in excess of
     tax basis earnings and profits be reported in the financial statements as a
     return of capital. Differences in the recognition or classification of
     income between the financial statements and tax earnings and profits which
     result in over-distributions for financial statement purposes are
     classified as distributions in excess of net investment income or
     accumulated net realized gains. 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). Transactions in Fund shares were as follows:

     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 of BMR's organization,
     officers and Trustees receive remuneration for their services to the Fund
     out of the investment adviser fee earned by BMR. Certain officers and
     Trustees of the Fund and of the Portfolio are officers and/or
     directors/trustees of the above organizations.


5    Distribution Plan
     ---------------------------------------------------------------------------
     The Fund has adopted a distribution plan (the "Plan") pursuant to Rule
     12b-1 under the Investment Company Act of 1940. The Plan requires the Fund
     to pay the Principal Underwriter, Eaton Vance Distributors, Inc. (EVD)
     amounts equal to 1/365 of 0.75% of each Fund's daily net assets, 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% of the aggregate amount received by the
     Fund for shares sold plus, (ii) distribution fees calculated by applying
     the rate of 1% over the prevailing prime rate to the outstanding balance of
     Uncovered Distribution Charges of EVD reduced by the aggregate amount of
     contingent deferred sales charges (see Note 6) and daily amounts
     theretofore paid to EVD. The amount payable to EVD with respect to each day
     is accrued on such day as a liability of the Fund and, accordingly, reduces
     the Fund's net assets. The Fund paid $7,753,143, to EVD representing 0.75%
     (annualized) of average daily net assets. At March 31, 1997 the amount of
     Uncovered Distribution Charges of EVD calculated under the Plan for the
     Fund was approximately $28,948,000.

     In addition, the Plan authorizes the Fund to make payments of service fees
     to the Principal Underwriter, Authorized Firms and other persons in amounts
     not exceeding 0.25% of the Fund's average daily net assets for each fiscal
     year. The Trustees have initially implemented the Plan by authorizing the
     Fund to make quarterly payments of service fees to the Principal
     Underwriter and Authorized Firms in amounts not expected to exceed 0.25%
     per annum of the Fund's average daily net assets based on the value of Fund
     shares sold by such persons and remaining outstanding for at least one
     year. The Fund paid or accrued service fees to or payable to EVD for the
     six months ended March 31, 1997 in the amount of $2,474,255. Service fee
     payments are made for personal services and/or the maintenance of
     shareholder accounts. Service fees paid to EVD and Authorized Firms 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.

     Certain officers and Trustees of the Fund are officers or directors of EVD.

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D



6    Contingent Deferred Sales Charge
     ---------------------------------------------------------------------------
     A contingent deferred sales charge (CDSC) is imposed on any redemption of
     Fund shares made within six years 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. The 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.
     No CDSC is levied on shares which have been sold to EVD or its affiliates
     or to their respective employees. CDSC charges are paid to EVD to reduce
     the amount of Uncovered Distribution Charges calculated under the 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 $2,280,000 of CDSC paid by shareholders for the period ended
     March 31, 1997.


7    Investment Transactions

/(2)/ When-issued security.

/(3)/ Non-income producing security.

/(4)/ Security has been issued as an inverse floater bond.

/(5)/ Security has been segregated to cover margin requirements on open

At March 31, 1997 the concentration of the Portfolio's investments in the
various states, determined as a percentage of total investments, is as follows:

               California 12.6% 
               Others, representing less than 10% individually 87.4%

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, 1997, 18.7% 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 financial institutions
ranged from 1.1% to 8.7% of total investments.

/(1)/ The expense ratios for the year ended September 30, 1995 and periods

NOTES TO FINANCIAL STATEMENTS (Unaudited)



1    Significant Accounting Policies
     ---------------------------------------------------------------------------
     National Municipals Portfolio (the Portfolio) is registered under the
     Investment Company Act of 1940 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. The following is a summary of
     significant accounting policies of the Portfolio. The policies are in
     conformity with generally accepted accounting principles.

     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. 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 or discount when required for federal
     income tax purposes.

     C Income 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 Deferred Organization Expenses -- Costs incurred by the Portfolio in
     connection with its organization are being amortized on the straight-line
     basis over five years.

     E 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 only to hedge against anticipated future changes in interest
     rates. Should interest rates move unexpectedly, the Portfolio may not
     achieve the anticipated benefits of the financial futures contracts and may
     realize a loss.

     F 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.

     G When-issued and Delayed Delivery Transactions -- The Portfolio may engage
     in when-issued or 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.

     H Use of Estimates -- The preparation of the financial statements in
     conformity with generally accepted accounting principles 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 revenue and expense during the reporting
     period. Actual results could differ from those estimates.

     I Other -- Investment transactions are accounted for on a trade date basis.

     J Expense Reduction -- Investors Bank & Trust Company (IBT) serves as
     custodian of the Portfolio. Pursuant to the custodian agreement, IBT
     receives a fee reduced by the 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 reflected as a reduction of operating expense on the Statement of
     Operations.

     K Interim Financial Information -- The interim financial statements
     relating to March 31, 1997 and for the six month period 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, 1997, the
     fee was equivalent to 0.44%(annualized) of the Portfolio's average net
     assets for such period and amounted to $4,810,748. 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,
     1997, no significant amounts have been deferred. Certain of the officers
     and Trustees of the Portfolio are officers and directors/trustees of the
     above organizations.


3    Investments
     ---------------------------------------------------------------------------
     Purchases and sales of investments, other than U.S. Government securities
     and short-term obligations, aggregated $216,993,467 and $301,600,458,
     respectively.


4    Federal Income Tax Basis of Investments
     ---------------------------------------------------------------------------
     The cost and unrealized appreciation/depreciation in value of the
     investments owned at March 31, 1997, as computed on a federal income tax
     basis, were as follows:
<TABLE> 

      <S>                                               <C> 
      Aggregate cost                                    $    1,985,587,205
     ---------------------------------------------------------------------------
      Gross unrealized appreciation                     $      165,519,624

      Gross unrealized depreciation                            (16,397,165)
     ---------------------------------------------------------------------------

      Net unrealized appreciation                       $      149,122,459
     ---------------------------------------------------------------------------
</TABLE> 


5    Line of Credit
     ---------------------------------------------------------------------------
     The Portfolio participates with other portfolios and funds managed by BMR
     and EVM and its affiliates in a $120 million unsecured line of credit
     agreement with a group of banks. Borrowing will be made by the portfolios
     or funds solely to facilitate the handling of unusual and/or unanticipated
     short-term cash requirements. Interest is charged to each portfolio or fund
     based on its borrowings at the bank's base rate or at an amount above
     either the bank's adjusted certificate of deposit rate, Eurodollar rate or
     federal funds effective rate. In addition, a fee computed at an annual rate
     of 0.15% on the daily unused portion of the facility is allocated among the
     participating portfolios and funds at the end of each quarter. For the six
     months ended March 31, 1997, the average daily loan balance was $11,098,132
     and the average interest rate was 6.22%. The maximum borrowings at any
     month end during the six months ended March 31, 1997 was $91,316,000. At
     March 31, 1997, the Portfolio had a balance outstanding pursuant to this
     line of credit of $44,769,000.


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 written options and futures 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 the 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.

     There were no outstanding obligations under these financial instruments at
     March 31, 1997.
