LETTER TO SHAREHOLDERS

[PHOTO OF THOMAS J. FETTER APPEARS HERE]

EV Marathon High Yield Municipals Fund had a total return of 14.7% for the year
ended January 31, 1998./1/ That return was the result of a rise in net asset
value per share from $10.62 on January 31, 1997 to $11.52 on January 31, 1998,
and the reinvestment of $0.61 in dividends. Based on its one-year performance,
the Fund was ranked fourth out of 45 funds in the High Yield Municipal Debt
category, as compiled by Lipper Analytical Services, Inc. - a nationally
recognized monitor of mutual fund performance. The average return for the group
was 11.0% for the same period./2/

Amid volatile global markets, more investors were drawn to municipal bonds...

1997 was a very good year for municipal bonds. Against a backdrop of moderate
economic growth and low inflation, investors again focused on the unique
features of municipals, which are among the last remaining tax-advantaged
vehicles. In addition, the municipal market attracted an increasing number of
crossover investors from other markets. Many investors bought municipals in a
flight to quality as the domestic equity market reached overvalued levels and
emerging markets were caught up in the turmoil of the Asian currency crisis.

A sound economy has resulted in improving municipal credits...

The upbeat economic climate of recent years has provided strong support for the
municipal market. Steady job growth has generated increased tax revenues for
states and local issuers. As a result, many areas hard-hit in the recessions of
the 1970s and 1980s have made a significant economic comeback, a fact reflected
in the value of their bonds. We expect to see many more such stories emerge in
the coming year.

1998 should bring more opportunities for municipal investors...

At present, there is little sign of inflation on the horizon, and, with the
Asian turmoil of recent months, it's possible that the economy may slow somewhat
in the next year. Meanwhile, the federal budget situation has improved
dramatically in the past several years. Naturally, those conditions are subject
to change over time, and we will continue to closely monitor economic progress.
As for the tax-exempt market, we believe that municipals will continue to serve
their traditional function of financing vital public works, while offering good
opportunities for tax-conscious investors.


                             Sincerely,

                             /s/ Thomas J. Fetter

MANAGEMENT DISCUSSION

[PHOTO OF THOMAS M. METZDA APPEARS HERE]

An interview with Thomas M. Metzold, portfolio manager of High Yield Municipals
Portfolio.

Q: Tom, how would you characterize the municipal bond market in 1997?

A: The municipal market turned in a strong performance. The Lehman Brothers
   Municipal Bond Index, for example, rose 9.5% in the year ended January 31./1/
   The overall bond market was helped by reports of continued low inflation, as
   ample labor and an increasingly global economy have held at bay most
   inflationary pressures.

   The municipal market did slightly underperform the Treasury market due to a
   rise in municipal supply. According to the Bond Market Association, long-term
   municipal issuance rose to more than $220 billion in 1997, up from around
   $190 billion the previous year. All in all, though, this was an excellent
   year for the tax-exempt market.

Q: The Fund again finished the year near the top of its competitive universe.
   What accounted for the excellent performance?

A: Our performance was bolstered by three factors. First, the Fund maintained a
   slightly longer-than-average duration than our peer group. As the good news
   about inflation filtered through the market, our longer average maturity
   helped the Fund participate more fully in the market rally.

   Second, as interest rates declined, the Fund benefited from a number of
   prerefundings, as higher-coupon bonds were advance-refunded by their issuers.
   Because these escrowed bonds are backed by Treasuries, their market value
   increases to reflect the fact they no longer have any credit risk.

   Finally, the compression of yields between high-quality and lower-quality
   bonds that has characterized the market in recent years continued in 1997.
   That especially benefited lower-quality bonds, the primary investment
   universe of the Portfolio.

Q: What were the Portfolio's largest sector concentrations?

A: The Portfolio remained well diversified. Among our largest sector weightings,
   the Portfolio was helped by the strong performance of industrial development
   bonds, as the relatively robust economy resulted in improving fundamentals
   for underlying projects. The Portfolio also had a large exposure to zero
   coupon bonds, which performed extremely well in a falling rate environment.
   Finally, we had a wide range of

   bonds in areas such as life-care facilities, assisted living projects, and
   nursing homes. These non-rated bonds also fared well as quality spreads
   narrowed.

Q: Industrial development bonds remained the largest weighting in the Fund. What
   did you find attractive about the IDB sector?

A: Industrial development bonds are tied to industrial activity and therefore
   provide higher coupons than some other segments of the tax-exempt market.
   Because they are tied to commercial enterprises, these bonds require company
   research as well. That plays into one of our strengths at Eaton Vance.

   The Portfolio's IDB investments included projects for paper companies,
   environmental and recycling projects, retailers, airlines, metals and
   utilities. In addition to producing jobs, these projects -- which include
   airports, pollution control facilities, and power generating plants --
   contribute to the well-being of the entire community.

Q: The prerefunding of some of its bonds continued to play a role in the Fund's
   success. Could you discuss that briefly?

A: With the decline in interest rates, many municipal issuers have sought to
   lower their interest costs by prerefunding their outstanding, high-coupon
   debt. Because these prerefunded bonds are backed by U.S. Treasuries, they are
   deemed to be of the highest quality, which is typically reflected in the
   market's pricing of the bond. In addition, escrowed bonds tend to perform
   much like Treasuries. In last year's market rally, that was additive to the
   Fund's performance.

Q: What did you find compelling about long-term care facilities, such as
   assisted living, nursing homes and life care projects?

A: We have made this area of the market an Eaton Vance specialty in recent
   years. The health care industry is changing rapidly and these long-term care
   facilities are playing an increasingly important role. They offer senior
   citizens a large measure of independence, together with a wide range of
   health care options. Accordingly, they have become popular with residents and
   investors alike.

   Typically, the bonds financing these facilities are non-rated and, therefore,
   require very rigorous analysis. As these projects have become more "seasoned"
   over time, investors have become more comfortable with the concepts and
   financial fundamentals, and the bonds have appreciated in price.

Q: You mentioned the recent "spread compression" among municipal bond yields.
   Could you expand on that thought?

A: Yes. Municipal quality spreads -- the difference in yields for bonds of
   varying quality -- have narrowed dramatically in the last decade. Ten years
   ago, the coupon for a BBB rated hospital bond would have been 300 basis
   points (3%) higher than a AAA-rated hospital bond. Today, that difference may
   be only around 25 basis points.

MANAGEMENT DISCUSSION CONT'D

   The compression in yield spreads has been the result of two related trends.
   First, insured bonds have increasingly dominated new municipal issuance. The
   widespread use of insurance by issuers has effectively eliminated quality
   spreads for a large segment of the investment grade market and made the
   municipal market increasingly generic. The second trend is a natural result
   of the first. Investors have turned to lower-rated bonds in an effort to find
   a yield advantage. The increasing demand for lower-rated bonds has
   contributed to even narrower spreads for lower-rated bonds.

Q: What is your outlook for the municipal market in the coming year?

A: With little sign of inflation, the outlook for bonds is generally favorable,
   although the economy will require watching for unexpected strength. We will
   also continue to monitor the optimistic budget scenario for any sign of
   deterioration.

   Moreover, following a successful year in the markets, I believe it makes good
   investment sense to review one's asset allocations. The equity market has
   just finished a remarkable run, with 1997 marking the third consecutive year
   of 20%-plus returns for the Dow Jones Industrial Average. That is well above
   the historical norm of 10% annual returns. As a result of that stock market
   run-up, many investors may now be over-allocated in equities.

   It may be prudent to adjust those portfolios slightly in favor of bonds.
   Municipal bonds represent an excellent way to diversify. And, of course,
   municipals provide excellent after-tax income, one of the few remaining ways
   to shelter income from taxes. I believe that municipal bonds remain a
   valuable, tax-efficient part of a comprehensive investment strategy.

  The chart compares the Fund's total return with that of the Lehman Brothers
  Municipal Bond Index, a broad-based, unmanaged market index of municipal
  bonds. Returns are calculated by determining the percentage change in net
  asset value (NAV) with all distributions reinvested. The lines on the chart
  represent the total returns of $10,000 hypothetical investments in the Fund
  and the Index. The Index's total return does not reflect commissions or
  expenses that would have been incurred if an investor individually purchased
  or sold the securities represented in the Index. It is not possible to invest
  directly in an Index.

**This figure reflects the Fund's maximum applicable contingent deferred sales
  charge (CDSC) deducted at redemption as follows: 5% - 1st and 2nd years; 4% -
  3rd year; 3% - 4th year; 2% - 5th year; and 1% - 6th year.

+ Returns are calculated by determining the percentage change in net asset value

  according to the schedule above.

  principal value will fluctuate so that shares, when redeemed, may be worth
  more or less their original cost.

EV Marathon High Yield Municipals Fund as of January 31, 1998 

NOTES TO FINANCIAL STATEMENTS 

1  Significant Accounting Policies
   -----------------------------------------------------------------------------
   EV Marathon High Yield Municipals Fund (the Fund) is a non-diversified series
   of Eaton Vance Municipals Trust II (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 High Yield 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 (63.1% at January 31, 1998). 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.

   On June 23, 1997, the Board of Trustees of the Trust adopted a multiple class
   plan for the Fund which permits the Fund to issue more than one class of
   shares. Initially, the Fund will offer three classes of shares and, effective
   February 1, 1998 the existing shares of the Fund will be designated Class B
   shares. On June 23, 1997, the Board of Trustees also approved a Plan of
   Reorganization (the "Plan") for the Trust. Under the terms of the Plan, the
   Fund will acquire substantially all of the assets and liabilities of EV
   Traditional High Yield Municipals Fund (the Traditional Fund) and EV Classic
   High Yield Municipals Fund (the Classic Fund). The transaction will be
   structured for tax purposes to qualify as a tax-free reorganization under the
   Internal Revenue Code. As a result of the reorganization, shareholders of the
   Traditional Fund will receive Class A shares and shareholders of the Classic
   Fund will receive Class C shares of the Fund. The reorganization will occur
   after the close of business, January 31, 1998.

   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 (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
   January 31, 1998, the Fund, for federal income tax purposes, had a capital
   loss carryover of $2,343,916, which will reduce the Fund's 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 January 31, 2005 ($79,992) and January 31, 2006
   ($2,263,924). Additionally, at January 31, 1998, net capital losses of
   $582,489 attributable to security transactions incurred after October 31,
   1997, are treated as arising on the first day of the Fund's next 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 Deferred Organization Expenses -- Costs incurred by the Fund in connection
   with its organization are being amortized on the straight-line basis over
   five years.

   E 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 maintain with
   IBT. All significant credit balances used to reduce the Fund's custodian fees
   are reported as a reduction of operating expenses in the Statement of

EV Marathon High Yield Municipals Fund as of January 31, 1998 

NOTES TO FINANCIAL STATEMENTS CONT'D

   F 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.

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

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 temporary over-distributions for
   financial statement purposes are classified as distributions in excess of net
   investment income or net realized gain on investments. Permanent differences
   between book and tax accounting relating to distributions are reclassified to
   paid-in capital.

3  Shares of Beneficial Interest
   -----------------------------------------------------------------------------
   The 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:

   ----------------------------------------------------------------------

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 advisor fee earned by BMR. Certain of the officers and Trustees of
   the Fund and the Portfolio are officers and directors/trustees of EVM and
   BMR.

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 the 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 the 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 amounts of contingent deferred sales charges (see
   Note 6) and 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 $1,160,366 to EVD
   for the year ended January 31, 1998, representing 0.75% of average daily net
   assets. At January 31, 1998, the amount of Uncovered Distribution Charges of
   EVD calculated under the Plan was approximately $7,433,000.

   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 any 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%

EV Marathon High Yield Municipals Fund as of January 31, 1998 

NOTES TO FINANCIAL STATEMENTS CONT'D

   of the Fund's average daily net assets for each fiscal year based on the
   value of Fund shares sold by such persons and remaining outstanding for at
   least one year. 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 where there are no outstanding
   Uncovered Distribution Charges of EVD. During the year ended January 31,
   1998, the Fund paid or accrued service fees to or payable to EVD under the
   Plan in the amount of $230,763.

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 gain distributions. The CDSC is imposed at declining rates that
   begin at 5% in the first and second year of redemption after purchase,
   declining one percentage point each subsequent year. No CDSC is levied on
   shares which have been sold to EVM or its affiliates or to their respective
   employees or clients. CDSC charges are paid to EVD to reduce the amount of
   Uncovered Distribution Charges calculated under the Fund's Distribution Plan.
   CDSC charges received when no Uncovered Distribution Charges exist will be
   credited to the Fund. EVD received approximately $514,000 of CDSC paid by
   shareholders for the year ended January 31, 1998.

7  Investment Transactions
   -----------------------------------------------------------------------------
   Increases and decreases in the Fund's investment in the Portfolio for the
   year ended January 31, 1998 aggregated $73,295,918 and $27,805,809,
   respectively.

8  Subsequent Event
   -----------------------------------------------------------------------------
   Effective February 1, 1998, the Fund changed its name to Eaton Vance High
   Yield Municipals Fund and shares of the Fund are designated Class B shares.
   Additional classes of shares are also offered.

INDEPENDENT AUDITORS' REPORT



To the Trustees and Shareholders
of Eaton Vance Municipals Trust II:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities of EV
Marathon High Yield Municipals Fund (one of the series of Eaton Vance Municipals
Trust II) as of January 31, 1998, the related statement of operations for the
year then ended, the statements of changes in net assets for the two years ended
January 31, 1998 and 1997 and the financial highlights for the two years ended
January 31, 1998 and 1997 and for the period from the start of business, August
7, 1995 to January 31, 1996. These financial statements and financial highlights
are the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion. 

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the EV Marathon High
Yield Municipals Fund (one of the series of Eaton Vance Municipals Trust II) at
January 31, 1998, and the results of its operations, the changes in its net
assets and its financial highlights for the respective stated periods, in
conformity with generally accepted accounting principles.

High Yield Municipals Portfolio as of January 31, 1998

NOTES TO FINANCIAL STATEMENTS


1  Significant Accounting Policies
   -----------------------------------------------------------------------------
   High Yield Municipals Portfolio (the Portfolio) is registered under the
   Investment Company Act of 1940, as a non-diversified open-end management
   investment company. The Portfolio, which was organized as a trust under the
   laws of the State of New York on May 1, 1995, seeks to provide high current
   income exempt from regular federal income tax. 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
   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 the 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 futures 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 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 when-issued or delayed delivery
   basis are marked to market daily and begin accruing interest on settlement
   date.

   H Expense Reduction -- 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
   balances the Portfolio maintains with IBT. All significant credit balances
   used to reduce the Portfolio's custodian fees are reported as a reduction of
   operating expenses in the Statement of Operations.

High Yield Municipals Portfolio as of January 31, 1998

NOTES TO FINANCIAL STATEMENTS CONT'D

   I 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.

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


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 sales of
   securities). For the year ended January 31, 1998, the fee was equivalent to
   0.60% of the Portfolio's average net assets for such period and amounted to
   $1,403,747. 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. Certain
   of the officers and Trustees of the Portfolio are officers and
   directors/trustees of the above organizations. 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 year ended January 31, 1998, no
   significant amounts have been deferred.


3  Investments
   -----------------------------------------------------------------------------
   Purchases and sales of investments, other than U.S. Government securities and
   short-term obligations, aggregated $116,143,507 and $17,403,200,
   respectively, for the year ended January 31, 1998.


4  Federal Income Tax Basis of Investments
   -----------------------------------------------------------------------------
   The cost and unrealized appreciation/depreciation in value of the investments
   owned at January 31, 1998, as computed on a federal income tax basis, were as
   follows:


   Aggregate cost                                                  $272,858,131 
   -----------------------------------------------------------------------------
                                                                                
   Gross unrealized appreciation                                     28,922,058 
                                                                                
   Gross unrealized depreciation                                       (647,884)
   -----------------------------------------------------------------------------
                                                                                
   Net unrealized appreciation                                       28,274,174 
   -----------------------------------------------------------------------------


5  Line of Credit
   -----------------------------------------------------------------------------
   The Portfolio participates with other portfolios and funds managed by BMR and
   EVM and its affiliates in a $100 million unsecured line of credit agreement
   with a group of banks. Borrowings will be made by the Portfolio solely to
   facilitate the handling of unusual and/or unanticipated short-term cash
   requirements. Interest is charged to each participating 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. At January 31,
   1998, the Portfolio had a balance outstanding pursuant to the line of credit
   of $2,502,000.


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 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 do 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. A summary of
   obligations under these financial instruments at January 31, 1998 is as
   follows:


    Futures
    Contracts
    Expiration                                                   Net Unrealized
    Date                  Contracts                 Position     Depreciation
    ----------------------------------------------------------------------------
    3/98                  500 U.S. Treasury Bonds   Short        $  881,125

INDEPENDENT AUDITORS' REPORT



To the Trustees and Investors
of High Yield Municipals Portfolio:
- --------------------------------------------------------------------------------
We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of High Yield Municipals Portfolio as of January
31, 1998, the related statement of operations for the year then ended, the
statements of changes in net assets for the years ended January 31, 1998 and
1997 and the supplementary data for the two years ended January 31, 1998 and for
the period from the start of business, August 7, 1995, to January 31, 1996.
These financial statements and supplementary data are the responsibility of the
Portfolio's management. Our responsibility is to express an opinion on these
financial statements and supplementary data based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and supplementary
data are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
January 31, 1998 by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion. 

In our opinion, such financial statements and supplementary data present fairly,
in all material respects, the financial position of the High Yield Municipals
Portfolio at January 31, 1998, and the results of its operations, the changes in
its net assets and its supplementary data for the respective stated periods, in
conformity with generally accepted accounting principles.
