EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND AS OF SEPTEMBER 30, 2000
--------------------------------------------------------------------------------
INVESTMENT UPDATE

Portfolio Manager


THE ECONOMY
--------------------------------------------------------------------------------

- The picture brightened somewhat for municipal bonds in the six-month period
  ended September 30, 2000. That was especially welcome following the
  disappointing returns of 1999, when bond funds, including Eaton Vance Limited
  Maturity Municipals Funds, reacted negatively to a succession of interest rate
  hikes.

- Following Federal Funds rate increases in March and again in May, the U.S.
  economy showed, in the ensuing months, the effects of the Fed's actions. In
  the third quarter, GDP growth slowed to a moderate 2.7%. While expressing
  concerns about sharply higher energy prices, the Federal Reserve left rates
  unchanged at its August meeting and signaled that its sustained string of rate
  hikes may be near an end.

THE FUND
--------------------------------------------------------------------------------

- During the six months ended September 30, 2000, the Fund's Class A, Class B
  and Class C shares had total returns of 3.35%, 2.93% and 2.94%,
  respectively.(1) For Class A and Class B, these returns resulted from an
  increase in net asset value (NAV) per share to $9.85 on September 30, 2000
  from $9.79 on March 31, 2000, and the reinvestment of $0.262 and $0.222 per
  share, respectively, in tax-free income.(2) For Class C, this return resulted
  from an increase in NAV to $9.22 from $9.16, and the reinvestment of $0.205
  per share in tax-free income.(2)

- Based on the most recent distributions and NAVs on September 30, 2000 of $9.85
  per share for Class A and Class B, and $9.22 for Class C, distribution rates
  were 5.31%, 4.51% and 4.44%, respectively.(3) The distribution rates of Class
  A, Class B and Class C are equivalent to taxable rates of 8.79%, 7.47% and
  7.35.(4)

- The SEC 30-day yields for Class A, B and C shares at September 30, 2000 were
  5.03%, 4.39% and 4.39%, respectively.(5) The SEC 30-day yields of Class A,
  Class B and Class C are equivalent to taxable yields of 8.33%, 7.27% and
  7.27%.(4)

MANAGEMENT UPDATE
--------------------------------------------------------------------------------

- Amid a slowing economy, the municipal bond market has responded favorably in
  recent months to the prospect of a more stable interest rate environment. The
  funds in the Lipper Intermediate Municipal Debt Fund Classification had an
  average total return of 3.27% in the six-month period ended September 30,
  2000, well above the -1.68% return for all of 1999.(6)

- Escrowed bonds represented a large weighting for the Portfolio. The bonds are
  escrowed and backed by Treasury bonds, and, therefore, are viewed as very high
  quality investments. An escrowed issue for a Maricopa County, Arizona
  Multifamily housing project was the largest holding.

- The Portfolio had a large exposure to industrial development revenue bonds.
  Management maintained a broad industry diversification, including paper,
  airlines and steel as well as non-cyclical areas such as food.

- The Portfolio took advantage of the prolonged rise in interest rates to
  establish tax losses that can be used to offset future capital gains. The
  proceeds of those sales were used to buy bonds with more attractive yields and
  trading characteristics.

(1) These returns do not include the 2.25% maximum sales charge for Class A
  shares or the applicable contingent deferred sales charges (CDSC) for Class B
  and Class C shares. (2) A portion of the Fund's income could be subject to
  federal income tax and/or alternative minimum tax, or state and local income
  tax. (3) 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.(4) Taxable-equivalent rates assume a
  maximum 39.6% federal income tax rate. A lower rate would result in lower
  tax-equivalent figures. (5) The Fund's SEC yield is calculated by dividing the
  net investment income per share for the 30-day period by the offering price at
  the end of the period and annualizing the result. (6) It is not possible to
  invest directly in an Index or Lipper Classification. (7) Portfolio
  Statistics, Ratings Distribution and 5 Largest Sectors are as of 9/30/00 only
  and may not be representative of the Portfolio's current or future
  investments. (8) 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.


  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. Yield will vary.

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND AS OF SEPTEMBER 30, 2000

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

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 (99.9% at
   September 30, 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 SEPTEMBER 30, 2000

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D

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

 G Interim Financial Statements -- The interim financial statements relating to
   September 30, 2000 and for the six months then ended have not been audited by
   independent certified public accountants, but in the opinion of the Fund's
   management reflect all adjustments, consisting only of normal recurring
   adjustments, necessary for the fair presentation of the financial statements.

2 Distributions to Shareholders
-------------------------------------------
   The net income of the Fund is determined daily and substantially all of the
   net income so determined is declared as a dividend to shareholders of record
   at the time of declaration. 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 SEPTEMBER 30, 2000

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) 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 $3,465 from the Fund as its
   portion of the sales charge on sales of Class A shares for the six months
   ended September 30, 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 six months ended
   September 30, 2000, the Fund paid or accrued $23,726 and $25,888 for Class B
   and Class C shares, respectively, to EVD, representing 0.75% (annualized) of
   the average daily net assets for Class B and Class C shares. At
   September 30, 2000, the amount of Uncovered Distribution Charges of EVD
   calculated under the Plan was approximately $1,074,000 and $5,199,000 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 six months ended September 30,
   2000 amounted to $55,233, $4,745, and $5,178 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 $6,000 and $0,000 of CDSC paid by shareholders for Class B
   shares and Class C shares, respectively, for the six months ended

7 Investment Transactions
-------------------------------------------
   Increases and decreases in the Fund's investment in the Portfolio for the six
   months ended September 30, 2000, aggregated $4,240,420 and $11,090,381,
   respectively.

8 Transfer of Net Assets
-------------------------------------------
   Prior to the opening of business on November 1, 1999, the Fund acquired the
   net assets of 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. In accordance with the
   agreement, the Fund issued 635,443 Class A and 105,507 Class B shares having
   a total aggregate value of $7,327,990 for Eaton Vance Connecticut Limited
   Maturity Municipals Fund net assets and 849,216 Class A and 51,811 Class B
   shares having a total aggregate value of $8,911,155 for Eaton Vance Michigan
   Limited Maturity Municipals Fund net assets. As a result, the Fund issued
   0.968 shares of Class A and Class B for each share of Class A and Class B of
   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
   Eaton Vance Michigan Limited Maturity Municipals Funds' net assets at the
   date of the transaction were $7,327,990 and $8,911,155 including $90,062 and
   $101,045 of unrealized appreciation, respectively. Directly after the merger,
   the combined net assets of the Eaton Vance National Limited Maturity
   Municipals Fund were $97,445,012 with a net asset value of $9.89, $9.89 and
   $9.25 for Class A, Class B and Class C, respectively.

 At September 30, 2000, the concentration of the Portfolio's investments in
 the various states, determined as a percentage of net assets, is as follows:

<TABLE>

Others, representing less than 10% individually             72.8%
</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 September 30, 2000, 13.9% 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 0.8% to 7.6% of total investments.

 (1)  Non-income producing security.

NATIONAL LIMITED MATURITY MUNICIPALS PORTFOLIO AS OF SEPTEMBER 30, 2000

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

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

                                       19

   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.

 J Interim Financial Statements -- The interim financial statements relating to
   September 30, 2000 and for the six months then ended have not been audited by
   independent certified public accountants, but in the opinion of the
   Portfolio'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 September 30, 2000, the fee was
   equivalent to 0.49% (annualized) of the Portfolio's average net assets for
   such period and amounted to $212,785. 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 six months ended September 30, 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 six months ended September 30, 2000.

4 Investments
-------------------------------------------
   Purchases and sales of investments, other than U.S. Government securities and
   short-term obligations, aggregated $1,991,092 and $7,631,679 respectively,
   for the six months ended September 30, 2000.

5 Federal Income Tax Basis of Investments
-------------------------------------------
   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at September 30, 2000, as computed on a federal income tax
   basis, were as follows:

<TABLE>
    <S>                                       <C>
    AGGREGATE COST                            $84,685,304
    -----------------------------------------------------
    Gross unrealized appreciation             $ 1,885,426
    Gross unrealized depreciation              (2,683,602)
    -----------------------------------------------------
    NET UNREALIZED DEPRECIATION               $  (798,176)
    -----------------------------------------------------
</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.

   At September 30, 2000, there were no outstanding obligations under these
   financial instruments.

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.
