                  Eaton Vance National Limited Maturity Municipals Fund,
[PHOTO]           Class A, had a total return of -1.68% for the year ended
                  March 31, 2000. That return was the result of a decrease in
Thomas J. Fetter  net asset value (NAV) to $9.79 on March 31, 2000 from $10.49
President         on March 31, 1999, and the reinvestment of $0.525 in dividends
                  exempt from regular federal income tax.(1)

Class B shares had a total return of -2.46% for the year ended March 31, 2000,
the result of a decrease in NAV to $9.79 from $10.49, and the reinvestment of
$0.445 in dividends exempt from regular federal income tax.(1)

Class C shares had a total return of -2.57% for the year ended March 31, 2000,
the result of a decline in NAV to $9.16 from $9.82, and the reinvestment of
$0.410 in dividends exempt from regular federal income tax.(1)

Based on the Fund's most recent dividends and net asset values of $9.79,
$9.79, and $9.16, the Fund's Class A, B and C shares had distribution rates
of 5.34%, 4.54%, and 4.47%, respectively, at March 31, 2000.2 The
distribution rates of Classes A, B and C are equivalent to taxable rates of
8.84%, 7.52% and 7.40%, respectively.(3)

SEC 30-day yields for Classes A, B, and C shares were 4.94%, 4.32%, and 4.22%,
respectively, at March 31, 2000.4 The SEC 30-day yields of Classes A, B and C
are equivalent to taxable yields of 8.18%, 7.15% and 6.99%, respectively.(3)

Municipal bonds finance vital
public projects while providing
relief to tax-weary investors...

Through their purchases of municipal bonds, investors provide financing for a
broad array of vital public works, including those for transportation
facilities, highway construction and industrial development. These projects not
only improve our quality of life, but also promote private enterprise and
create new jobs.

Adding to their unique role, municipal bonds are among the few tax-advantaged
vehicles remaining for investors. Eaton Vance National Limited Maturity
Municipals Fund will continue its traditional investment pursuit: maintaining a
portfolio of primarily investment-grade quality, intermediate-term bonds with
competitive levels of tax-exempt income. Our goal remains to provide excellent
income opportunities for today's tax-burdened investors.

                             Sincerely,

                             /s/ Thomas J. Fetter

Federal income tax information on distributions. For federal income tax
purposes, 99.62% of the total dividends paid by the Fund from net investment
income during the year ended March 31, 2000 was designated as an
exempt-interest dividend.

(1) These returns do not include the 2.25% maximum sales charge for the Fund's
Class A shares or the applicable contingent deferred sales charge (CDSC) for
Class B or C shares. A portion of the Fund's income may be subject to federal
income and/or federal alternative minimum tax. Income may be subject to state
tax. (2) The Fund's distribution rate represents actual distributions paid to
shareholders and is calculated by dividing the last distribution per share
(annualized) by the net asset value. (3) Taxable-equivalent figures assume
maximum 39.6% federal income tax rate. A lower rate would result in lower
tax-equivalent figures. (4) 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. (5) Returns are historical
and are calculated by determining the percentage change in net asset value with
all distributions reinvested. SEC returns for Class A reflect the maximum 2.25%
sales charge. SEC returns for Class B reflect applicable CDSC based on the
following schedule: 3% - 1st year; 2.5% - 2nd year; 2% - 3rd year; 1% - 4th
year. Class C 1-year SEC return reflects 1% CDSC. (6) Five largest sector
weightings account for 52.0% of the Portfolio's investments, determined by
dividing the total market value of the holdings by the total investments of the
Portfolio. Holdings are subject to change.

Past performance is no guarantee of future results. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost.

                    AN INTERVIEW WITH
[PHOTO]             WILLIAM H. AHERN,
                    PORTFOLIO MANAGER OF
William H. Ahern    EATON VANCE NATIONAL LIMITED
Portfolio Manager   MATURITY MUNICIPALS FUND.

                    Q:   Bill, the fixed-income markets featured a good deal of
                         volatility in the past year. What contributed to this
                         volatile climate?

A:   There were several factors. First, the Federal Reserve's actions have
     pushed interest rates significantly higher, with the greatest impact on the
     short-term and intermediate-term segments of the market. Second, the
     investment climate has been made more difficult by the inversion of the
     yield curve. That is, short-term bond yields have risen more than long-term
     yields. This inversion was not seen in the municipal market, but shifts in
     the Treasury curve impact supply and demand in the municipal market.
     Finally, the stock market rallied through much of the period, creating a
     difficult competitive environment for fixed-income investments, including
     the municipal market.

Q:   What brought about the inversion of the yield curve?

A:   The Federal Reserve has been relentless in its fight against potential
     inflation, raising short-term rates five times in the past year. The Fed's
     actions have resulted in sharply higher short-term rates. However,
     investors in LONGER-TERM bonds have applauded the Fed's efforts because
     inflation poses the greatest threat to longer-duration investments. As a
     result, interest rates have risen less at the longer-end of the yield
     curve.

     In addition, the Treasury department has indicated plans to selectively buy
     back longer-term bonds, which will significantly limit supply. That specter
     has further accentuated the inversion of the curve. Five-year municipal
     yields rose from 3.90% on March 31, 1999 to 4.98% on March 31, 2000, a rise
     of 108 basis points (1.08%). In contrast, thirty-year municipal yields rose
     from 5.21% to 5.88%, a rise of just 67 basis points (.67%).

Q:   How have you structured the Portfolio in that difficult environment?

A:   Escrowed bonds - bonds that have been pre- refunded in anticipation of
     their call date and backed by Treasury bonds - remained the Portfolio's
     largest sector weighting at March 31, constituting 17.1% of the Portfolio.

     largest weighting consisted of industrial development revenue bonds (IDB),
     which represented 12.0% of the Portfolio. Cogeneration bonds followed, at
     8.0% of the Portfolio.

Q:   Escrowed bonds were the Portfolio's largest concentration. Why have you
     found them attractive?

A:   Escrowed bonds are those which have been pre-refunded by their issuers and
     are valued by investors for their perceived quality and relative high
     income. Issued when prevailing interest rates were much higher, they tend
     to carry very attractive coupons. Because they are backed by Treasury
     bonds, they are deemed to be of the very highest quality. Finally, because
     they are escrowed to their nearest call date, their prices tend to be more
     stable. Thus, they can be an excellent defensive investment, especially in
     a volatile climate such as we've just been through.

Q:   Industrial development revenue bonds were again a major focus of the
     Portfolio. Where were you invested?

A:   The Portfolio's IDB holdings were diversified along a broad range of
     industries and locales and included projects for some nationally recognized
     companies. The Portfolio's bonds

Your Investment at Work
- ---------------------------------------------------------
     Connecticut Airport
     Bradley International Airport

- -    These bonds were issued to finance the the costs of terminal and
     maintenance facility expansion at Bradley International Airport in Windsor
     Locks. Expansion of gates and parking facilities is scheduled for
     completion in 2003.
- -    Passenger traffic at Bradley increased 21% in March over the same period a
     year ago. The surge is tied to the onset of service by Southwest Airlines.
     Delta Airlines plans to commence Bradley's first international service in
     June.
- -    The bond carries an attractive 7.40% coupon. This issue was representative
     of the Portfolio's efforts to find good income opportunities in
     higher-yielding bonds.
- --------------------------------------------------------------------------------

     included such projects as a solid waste facility in Missouri for Proctor &
     Gamble; an expanded terminal in Colorado for American Airlines; and a
     facility in Connecticut for Frito-Lay. These bonds supported economic
     growth for industry while providing excellent income opportunities for
     investors.

Q:   Cogeneration bonds were a fairly large investment. What sort of projects do
     they finance?

A:   Cogeneration facilities use by-products of energy generation to create
     additional energy. A plant that creates electric energy will use the excess
     heat created by turbines to create steam energy. These newer technologies
     are considered environmentally friendly because they produce significantly
     fewer emissions.

     In addition, because they utilize what would otherwise be wasted,
     cogeneration facilities are generally more efficient than previous
     technologies and may produce large savings over the lifetime of a facility.
     For example, in Colver, Pennsylvania, a state Economic Devolopment
     Authority issue financed a 102-megawatt facility that generates
     electricity. The plant utilizes 552,000 tons annually of bituminous coal
     refuse left over from many years of coal mining in the region.

Q:   Did senior life care facilities continue to play a role in the Portfolio?

A:   Yes. This sector remained a good source of tax-exempt income. In a rapidly
     aging nation, these projects have become increasingly popular in recent
     years. Typically, private rooms, meals, exercise and social activities are
     provided, as is the availability of medicare care, when needed. The needs
     of residents may vary widely, ranging from a high degree of independence to
     a more elaborate degree of care.

     The Portfolio focused on projects with proven concepts and on providers
     that are likely to remain among the leaders. From a credit standpoint,
     these are typically research-intensive, non-rated bonds. Utilizing our
     extensive

     research capabilities in the non-rated segment of the municipal market, we
     have been able to find some excellent, higher-yielding opportunities in
     these sectors.

Q:   Bill, what is your outlook for the municipal market in the coming year?

A:   I believe that the outlook for municipal bonds is generally favorable.
     While the economy continues to grow, increases in productivity, global
     competition and the continued vigilance of the Federal Reserve are helping
     to keep inflation under control. Over the short-term, of course, we can't
     rule out the possibility of further Fed rate hikes. That would create some
     temporary hurdles. However, over the longer-term, with the likelihood of
     increasing budget surpluses at the Federal level and the pay-down of
     long-term debt, there is room for optimism about intermediate-term bonds.

  The chart compares the total return of the Fund's Class B shares with that of
  the Lehman Brothers 7-Year Municipal Bond Index, a broad-based, unmanaged
  market index of intermediate-term 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.
  An investment in the Fund's Class A shares on 6/27/96 at net asset value would
  have been worth $11,734 on March 31, 2000; $11,471, including the Fund's 2.25%
  maximum sales charge. An investment in the Fund's Class C shares on 12/8/93 at
  net asset value would have been worth $11,877 on March 31, 2000.

**Returns are calculated by determining the percentage change in net asset value
  (NAV) with all distributions reinvested. SEC returns for Class A reflect the
  maximum 2.25% sales charge. SEC returns for Class B reflect applicable CDSC
  based on the following schedule: 3% - 1st year; 2.5% - 2nd year; 2% - 3rd
  year; 1% - 4th year. SEC 1-Year return for Class C reflects 1% CDSC.

Past performance is no guarantee of future results. Investment return and
principal value will fluctuate so that shares, when redeemed, may be worth more
or less than their original cost.

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND AS OF MARCH 31, 2000

NOTES TO FINANCIAL STATEMENTS

1 Significant Accounting Policies
- -------------------------------------------
   Eaton Vance National Limited Maturity Municipals Fund (the Fund) is a
   diversified series of Eaton Vance Investment 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 three classes of
   shares: Class A, Class B and Class C 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). Class B shares held longer than (i) four
   years or (ii) the time at which the contingent deferred sales charge
   applicable to such shares expires will automatically convert to Class A
   shares. 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 or 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 the National Limited Maturity 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 (99.99% at March
   31, 2000). 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 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 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
   March 31, 2000, the Fund, for federal income tax purposes, had a capital loss
   carryover of $5,823,610 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 tax. Such capital loss carryover will expire on
   March 31, 2002 ($637,442), March 31, 2003 ($2,468,748), March 31, 2004
   ($1,216,547), March 31, 2005 ($1,120,027), March 31, 2006 ($320,446), and
   March 31, 2007 ($60,400). 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 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 income and expense during the reporting period. Actual results could
   differ from those estimates.

 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 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.

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND AS OF MARCH 31, 2000

NOTES TO FINANCIAL STATEMENTS CONT'D

 F 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. Dividends are declared separately for each class
   of shares. Distributions are paid monthly. Distributions of allocated
   realized capital gains, if any, are made at least annually. Shareholders may
   reinvest income and capital gain distributions in additional shares of the
   same class of the Fund at the net asset value as of the reinvestment 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. 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. The tax treatment of
   distributions for the calendar year will be reported to shareholders prior to
   February 1, 2001 and will be based on tax accounting methods which may differ
   from amounts determined for financial statement purposes.

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:

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND AS OF MARCH 31, 2000

NOTES TO FINANCIAL STATEMENTS CONT'D

4 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. Certain officers and Trustees of the Fund
   and of the Portfolio are officers of the above organizations. The Fund was
   informed that Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and
   the Fund's principal underwriter, received $3,489 from the Fund as its
   portion of the sales charge on sales of Class A shares for the year ended
   March 31, 2000.

   Except as to Trustees of the Fund and the Portfolio who are not members of
   EVM's organization, officers and Trustees receive remuneration for their
   services to the Fund out of such investment adviser fee.

5 Distribution and Service Plans
- -------------------------------------------
   The Fund has in effect a distribution plan for Class B shares (Class B Plan)
   and for 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
   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) 3% of the aggregate amount received by the Fund for Class B
   shares sold, 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
   amounts theretofore paid to or payable 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. For the year ended March 31,
   2000, the Fund paid or accrued $43,918 and $75,102 for Class B and Class C
   shares, respectively, to EVD, representing 0.75% of the average daily net
   assets for Class B and Class C shares. At March 31, 2000, the amount of
   Uncovered Distribution Charges of EVD calculated under the Plan was
   approximately $1,040,000 and $4,924,000 for Class B and Class C shares,
   respectively.

   The Plans authorize each class to make payments of service fees to EVD,
   investment dealers and other persons in amounts not exceeding 0.25% of the
   Fund's average daily net assets for each fiscal year. The Trustees initially
   implemented the Plans by authorizing the Fund to make quarterly payments of
   service fees to EVD and investment dealers in amounts equal to 0.15% per
   annum of the Fund's average daily net assets attributable to Class A and
   Class B shares based on the value of Fund shares sold by such persons and
   remaining outstanding for at least one year. On October 4, 1999 the Trustees
   approved the service fee payments equal to 0.15% per annum of the Trust's
   average daily net assets attributable to Class A and Class B shares for any
   fiscal year on shares of the Trust sold on or after October 12, 1999. The
   Class C Plan permits the Fund to make monthly payments of service fees in
   amounts not expected to exceed 0.25% of the Fund's average daily net assets
   attributable to Class C shares for any 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 year ended March 31, 2000
   amounted to $93,077, $8,880, and $25,034 for Class A, Class B, and Class C
   shares, respectively.

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

6 Contingent Deferred Sales Charge
- -------------------------------------------
   A contingent deferred sales charge (CDSC) generally is imposed on redemptions
   of Class B shares made within four 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 Class B and Class C shares acquired by
   reinvestment of dividends or capital gains distributions. The CDSC for
   Class B shares is imposed at declining rates that begin at 3% in the case of
   redemptions in the first year of purchase. Class C shares are 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 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 $481,000 and $7,000
   of CDSC paid by shareholders for Class B shares and Class C shares,
   respectively, for the year ended March 31, 2000.

   As a result, the Fund issued 0.965 shares of Class A and one share of
   Class C for each share of EV Traditional National Limited Maturity Municipals
   Fund and EV Classic National Limited Maturity Municipals Fund, respectively.
   The transaction was structured for tax purposes to qualify as a tax free

   Limited Maturity Municipals Fund's and EV Classic National Limited Maturity
   Municipals Fund's net assets at the date of the transaction were $12,949,960

   Eaton Vance Connecticut Limited Maturity Municipals Fund and 0.940 shares of
   Class A and Class B for each share of Class A and Class B of Eaton Vance
   Michigan Limited Maturity Municipals Fund. The transaction was structured for
   tax purposes to qualify as a tax free reorganization under the Internal
   Revenue Code. The Eaton Vance Connecticut Limited Maturity Municipals and

 At March 31, 2000, the concentration of the Portfolio's investments in the
 various states, determined as a percentage of net assets, is as follows:

<TABLE>
<S>                                                        <C>

Others, representing less than 10% individually            85.1%
</TABLE>

 The Portfolio invests primarily in debt securities issued by municipali-
 ties. 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, 2000, 17.4% 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 1.3% to 10.0% of total investments.

 (1)  Non-income producing security.

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

 (3)  When-issued security.

NATIONAL LIMITED MATURITY MUNICIPALS PORTFOLIO AS OF MARCH 31, 2000

NOTES TO FINANCIAL STATEMENTS

1 Significant Accounting Policies
- -------------------------------------------
   National Limited Maturity Municipals Portfolio (the Portfolio) seeks to
   provide (1) a high level of income exempt from regular federal income tax and
   (2) limited principal fluctuation. 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 accretion of 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 respective 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 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.

 E 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.

 F 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.

 G 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
   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 in the Statement of Operations.

 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 income 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.
   Realized gains and losses are computed based on the specific identification
   of the securities sold.

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 year ended March 31, 2000, the fee was equivalent to
   0.48% of the Portfolio's average net assets for such period and amounted to
   $429,856. 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
   officers and Trustees of the Portfolio are officers 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 March 31, 2000, no significant amounts
   have been deferred.

3 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. Borrowings may 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. The National
   Limited Maturity Municipals Portfolio did not have any significant borrowings
   or allocated fees during the year ended March 31, 2000.

4 Investments
- -------------------------------------------
   Purchases and sales of investments, other than U.S. Government securities and
   short-term obligations, aggregated $29,054,227 and $23,894,787 respectively,
   for the year ended March 31, 2000.

5 Federal Income Tax Basis of Investments
- -------------------------------------------
   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at March 31, 2000, as computed on a federal income tax
   basis, were as follows:

<TABLE>
    <S>                                       <C>

    -----------------------------------------------------
    NET UNREALIZED DEPRECIATION               $(1,242,170)
    -----------------------------------------------------
</TABLE>

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.

   A summary of obligations under these financial instruments as of March 31,
   2000, is as follows:

7 Transfer of Net Assets
- -------------------------------------------
   Prior to the opening of business on November 1, 1999, Eaton Vance Connecticut
   Limited Maturity Municipals and Eaton Vance Michigan Limited Maturity
   Municipals Funds, pursuant to an Agreement and Plan of Reorganization dated
   November 1, 1999, contributed securities with a market value of $7,443,241
   and $8,864,366, including $88,630 and $97,151 of unrealized appreciation
   respectively. The transaction was structured for tax purposes to qualify as a
   "tax free" reorganization under the Internal Revenue Code.

are the responsibility of the Trust's management. Our responsibility is to

perform the audit to obtain reasonable assurance about whether the financial
