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
   2.5%./1/

 .  This return resulted from a decrease in net asset value per share to $10.52
   on March 31, 1997 from $10.58 on September 30, 1996, and the reinvestment of
   $0.321 per share in tax-free income dividends./2/

 .  Based on the Fund's most recent dividend, and a net asset value of $10.52 per
   share, the Fund's distribution rate on March 31, 1997 was 6.13%.

 .  To equal 6.13% in a taxable investment, a couple in the 36% combined federal
   and state tax bracket would need a yield of 9.58%.

   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.

      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.

EV Traditional National Municipals Fund as of March 31, 1997 

NOTES TO FINANCIAL STATEMENTS (Unaudited)




1 Significant Accounting Policies
  ------------------------------------------------------------------------------
  EV Traditional 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 the 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 (1.8% 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 $158,203
  which will reduce the taxable income arising from future net realized gain on
  investments, if any, to the extent permitted by the Internal Revenue Code and
  thus will reduce the amount of 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, 2002
  ($20) and September 30, 2004 ($158,183). Dividends paid by the Fund from net
  interest on tax-exempt 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 Deferred Organization Expenses -- Costs incurred by the Fund in connection
  with its organization, including registration costs, are being amortized on
  the straight-line basis over five years.

  E 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.

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

  G 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.


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. Distributions of
  allocated realized capital 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 only 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

5 Service Plan

  Inc. (EVD), a subsidiary of Eaton Vance Management, Authorized Firms or other
  persons in amounts not exceeding 0.25% of the Fund's average daily net assets
  for any fiscal year. The Trustees have initially implemented the Plan by
  authorizing the Fund to make quarterly service fee payments to the Principal
  Underwriter and Authorized Firms in amounts not exceeding 0.25% of the Fund's
  average daily net assets for any fiscal year which is attributable to shares
  of the Fund sold by such persons and remaining outstanding for at least one
  year. Service fee payments are made for personal services and/or the
  maintenance of shareholder accounts. The Fund paid or accrued service fees for

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 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.

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D


  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:

  <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.
