LETTER TO SHAREHOLDERS

[PHOTO OF THOMAS J. FETTER]
Thomas J. Fetter
President

In our shareholder reports, we refer frequently to "quality spreads" and their
important role in bond analysis. However, while followed closely by bond
analysts and portfolio managers, this aspect of municipal bond investing is
generally overlooked by individual investors. As part of our continuing
educational series, we thought it might be instructive to discuss quality
spreads and why they constitute a key variable for investors in the municipal
bond market.

QUALITY SPREADS: COMPENSATION FOR ADDED CREDIT RISK...

The term "quality spread" refers to the difference in yields between bonds of
varying quality but similar maturities. A bond rated BBB, for example, should
have a higher yield than an insured bond rated AAA because investors who buy
lower-quality bonds anticipate being paid for accepting a higher level of credit
risk. That risk premium comes in the form of higher yields. Spreads are
typically stated in basis points, or 1/100's of a percentage point. Thus, a bond
yielding 5.00% trades at a spread of 100 basis points (1.00%) over a bond that
yields 4.00%.

SPREAD FLUCTUATIONS ARE INFLUENCED BY A VARIETY OF FACTORS...

Spreads fluctuate with changes in market conditions, with many factors
influencing spread relationships. The quality and type of bond are primary
factors. For example, an insured general obligation rated AAA - with no credit
risk - will trade at a significantly lower yield than a BBB-rated industrial
bond, which has a significantly higher credit risk. Naturally, a bond's price
will respond to changes that may impact - for better or worse - the underlying
fundamentals of an issuer. Remember, bond yields move in the opposite direction
of bond prices.

Another factor that influences spreads is supply. Assuming stable demand,
spreads are likely to widen if the supply for a specific issuer increases, as
the market must now digest a larger volume of bonds. Similarly, if supply
declines, spreads may narrow, as investors may be willing to pay more for a
credit that is increasingly scarce.

Finally, quality spreads may fluctuate with changes in the overall economy. For
example, spreads tend to narrow as the economy strengthens and the revenue
outlook improves. On the other hand, as the economy slows or enters recession,
spreads tend to widen, as investors become increasingly worried about the
direction of the economy and its impact on bonds with higher credit risk.

SPREADS CONSTITUTE A KEY FACTOR IN INVESTMENT DECISIONS...

Quality spreads play an important role in the investment decisions of municipal
bond portfolio managers. The widening of spreads may suggest a developing
opportunity. If spreads have widened appreciably, the investor may detect an
unusual opportunity in a lower-quality, higher-yielding bond. Conversely, if
lower-quality bonds have significantly outperformed high-quality bonds over a
period, the resulting narrowing of spreads may signal the need for caution. This
"spread compression" may prompt portfolio managers to upgrade their portfolios
with higher-quality bonds because they are no longer being adequately
compensated for the risk of owning lower-quality bonds.

While quality spreads are a key metric for municipal bond investors, they
represent just one of many factors considered in establishing a diversified bond
portfolio. At Eaton Vance, we realize that complex markets require intensive
research, a need that emphasizes once again the value of experienced,
professional portfolio management.

                                 Sincerely,


                                 /s/ Thomas J. Fetter

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND as of September 30, 2003
MARKET RECAP

While the pace of job growth was disappointing, the U.S. economy improved
noticeably in the six months ended September 30, 2003. The passage of
significant tax legislation appeared to give consumer spending a boost. Capital
spending, which has lagged the recovery rate of past expansions, was at last
showing signs of recovery in late summer and early fall, as manufacturers of
industrial equipment reported stronger orders.

TECHNOLOGY, RETAILING AND CONSTRUCTION HAVE LED THE ECONOMY IN THE EARLY STAGES
OF RECOVERY...

A nascent recovery was evident in several key sectors of the economy. Technology
companies, especially semiconductor manufacturers and suppliers, have reported
robust demand. The manufacturing sector also saw a pickup in activity, with
industrial segments, such as machine tools, faring well, as factories began to
refit their plants. The retail sector - with the exception of weak auto sales -
was very strong, as consumer confidence rose and tax cuts filtered into
consumers' pockets. Despite a rise in mortgage rates, residential construction
maintained its strong momentum, although the commercial side was quite sluggish.

WITH SLOW JOB GROWTH AND MANAGEABLE INFLATION, THE FEDERAL RESERVE HAS KEPT
INTEREST RATES LOW...

Gross Domestic Product expanded 3.3% in the second quarter of 2003, followed by
a 7.2% rise in the third quarter. However, despite the rebounding economy, the
labor market remained stagnant through much of the year - the nation's jobless
rate was 6.1% in September 2003. While large employers were slow to rehire, the
pace of layoffs slowed considerably. Job growth was stronger among temporary
agencies and smaller firms, which have generated the lion's share of new jobs in
recent years.

Core inflation has generally been contained. Prices for finished goods, consumer
staples and services have seen little change. However, prices for some
commodities have witnessed a sharp rise, including lumber, plywood, steel and
natural gas. Mean-while, gasoline prices, which spiked dramatically during the
prime summer driving season, have since fallen back slightly. With inflation
largely held at bay, the Federal Reserve has maintained an accommodative
monetary policy. The Fed lowered its Federal Funds rate - a key short-term
interest rate barometer - to 1.00% in June.

However, while the decline in short-term interest rates helped revive the stock
market, longer-term interest rates moved slightly higher, prompting a bond
market pullback. Ten-year Treasury bond yields - which were at 3.80% at March 31
- - rose to 3.93% by September 30, 2003 in response to a reviving economy. The
Lehman Brothers Municipal Bond Index had a total return of 2.66% for the six
months ended September 30, 2003.*

FACING RISING BUDGET SHORTFALLS, BELEAGUERED STATES HAVE BEEN FORCED TO RAISE
TAXES...

Despite lower federal tax rates, the rationale for tax-exempt income has
remained intact. Many state governments have enacted income tax hikes and fee
increases to make up for revenue shortfalls and budget deficits. Thus, while one
portion of the tax burden has fallen, another portion has grown more onerous for
many taxpayers. For that reason, we believe that municipal bonds will continue
to present interesting investment opportunities and to merit a place in the
portfolios of tax-conscious investors.

INVESTMENT UPDATE

Portfolio Manager

MANAGEMENT UPDATE

- - The U.S. economy gathered new momentum in 2003. Consumer-based sectors, such
  as retail, have mounted a recovery, housing remains relatively strong and
  manufacturing appears to be on the mend in many parts of the nation. The U.S.
  jobless rate was 6.1% in September 2003, up from 5.6% a year ago.

- - Electric utility bonds were the Portfolio's largest weighting at September 30,
  2003. These essential service issuers receive revenues from user fees and are
  typically considered less economically-sensitive than industrial issuers.

- - Insured* transportation bonds were prominent in the Portfolio. Investments
  included bonds that financed a representative array of the nation's
  transportation infrastructure, such as turnpikes, highways, airports, bridges
  and tunnels and port facilities.

- - While hospital bonds remained large holdings, management was very selective.
  Management focused on institutions that we believe have good demographic and
  market positions, favorable cost structures and established reputations for
  health care specialties.

- - Management adjusted the Portfolio's coupon structure with changing market
  conditions and improved call protection. With the prospect of increased
  refundings, call protection remains a very important consideration for
  municipal investors.

     last distribution per share (annualized) by the net asset value (NAV). (4)
     Taxable-equivalent rates assume maximum 35.00% 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) Portfolio Statistics, Rating Distribution and 5
     Largest Sectors are as of 9/30/03 only and may not be representative of the
     Portfolio's current or future investments. (7) Returns are historical and
     are calculated by determining the percentage change in 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; Class C shares are subject to 1% CDSC within 1st year.

     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.

(1)  Net investment income per share was computed using the average shares
     outstanding.

(2)  The Fund, through its investment in the Portfolio, has adopted the
     provisions of the revised AICPA Audit and Accouting Guide for Investment
     Companies and began using the interest method to amortize premiums on
     fixed-income securities. The effect of this change for the year ended March
     31, 2002 was to increase net investment income per share by $0.002, and
     increase net realized and unrealized losses per share by $0.002, and
     increase the ratio of net investment income to average net assets from
     4.83% to 4.85%. Per share data and ratios for the periods prior to April 1,
     2001 have not been restated to reflect this change in presentation.

(3)  Returns are historical and are calculated by determining the percentage
     change in net asset value with all distributions reinvested. Total return
     is not computed on an annualized basis.

(4)  Includes the Fund's share of the Portfolio's allocated expenses.

(5)  Annualized.

EATON VANCE NATIONAL LIMITED MATURITY MUNICIPALS FUND as of September 30, 2003
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. In
   addition, Class B shares acquired through the reinvestment of distributions
   will also convert to Class A shares in proportion to shares not acquired
   through reinvestment. 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 paid shares of each class 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, 2003). 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 accounting principles generally accepted in
   the United States of America.

   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.

   C EXPENSES -- The majority of expenses of the Trust are directly identifiable
   to an individual fund. Expenses which are not readily identifiable to a
   specific fund are allocated taking into consideration, among other things,
   the nature and type of expense and the relative size of the funds.

   D 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 income, 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, 2003, the Fund, for federal income tax purposes, had a capital loss
   carryover of $4,831,650 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 as
   follows on: March 31, 2004, $1,216,547, March 31, 2005, $1,120,027, March 31,
   2006, $320,446, March 31, 2007, $60,400, March 31, 2009, $248,691, March 31,
   2010, $146,034 and March 31, 2011, $1,719,505. 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.

   E USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America 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.

                                       10
<Page>

   F EXPENSE REDUCTION -- Investors Bank & Trust Company (IBT) serves as
   custodian to the Fund and the Portfolio. Pursuant to the respective custodian
   agreements, IBT receives a fee reduced by credits which are determined based
   on the average daily cash balances the Fund or the Portfolio maintains with
   IBT. All significant credit balances used to reduce the Fund's custodian fees
   are reported as a reduction of total expenses in the Statement of Operations.

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

   H INTERIM FINANCIAL STATEMENTS -- The interim financial statements relating
   to September 30, 2003 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  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. Accounting
   principles generally accepted in the United States of America require that
   only distributions in excess of tax basis earnings and profits be reported in
   the financial statements as a return of capital. 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, 2004 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:

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. Except as to Trustees of the Fund and
   Portfolio who are not members of EVM's or BMR's organization, officers and
   Trustees receive remuneration for their services to the

                                       11
<Page>

   Fund out of such investment adviser fee. EVM serves as the sub-transfer agent
   of the Fund and receives from the transfer agent an aggregate fee based upon
   the actual expenses incurred by EVM in the performance of those services. The
   Fund was informed that Eaton Vance Management (EVM) earned $3,830 from the
   transfer agent for the six months ended September 30, 2003. The Fund was
   informed that Eaton Vance Distributors, Inc. (EVD), a subsidiary of EVM and
   the Fund's principal underwriter, received $12,514 from the Fund as its
   portion of the sales charge on sales of Class A shares for the six months
   ended September 30, 2003.

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 and 6.25% of Class C sales of the amount received by the Fund for each
   share sold and, (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, 2003, the Fund paid
   or accrued $129,885 and $194,789 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, 2003, the amount
   of Uncovered Distribution Charges of EVD calculated under the Plan was
   approximately $1,447,000 and $9,018,000 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 approved
   quarterly service fee payments equal to 0.15% per annum of the Fund's average
   daily net assets attributable to Class A, Class B, and Class C shares for
   each 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, 2003 amounted to $91,274,
   $25,977, and $38,958 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 $32,000 and $15,000 of
   CDSC paid by shareholders for Class B shares and Class C shares,
   respectively, for the six months ended September 30, 2003.

7  INVESTMENT TRANSACTIONS

   Increases and decreases in the Fund's investment in the Portfolio for the six
   months ended September 30, 2003, aggregated $53,584,675 and $40,055,061,
   respectively.

The Portfolio invests primarily in debt securities issued by municipalities. The
ability of the issuers of the debt securities to meet their obligations may be
affected by economic developments in a specific industry or municipality. In
order to reduce the risk associated with such economic developments, at

NATIONAL LIMITED MATURITY MUNICIPALS PORTFOLIO as of September 30, 2003
NOTES TO FINANCIAL STATEMENTS (Unaudited)


1  SIGNIFICANT ACCOUNTING POLICIES

   The objective of National Limited Maturity Municipals Portfolio (the
   Portfolio) is to provide high current income exempt from regular federal
   income tax. 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. At September 30, 2003, the Eaton Vance National Limited Maturity
   Municipals Fund held an approximate 99.9% interest in the Portfolio. The
   following is a summary of significant accounting policies of the Portfolio.
   The policies are in conformity with accounting principles generally accepted
   in the United States of America.

   A INVESTMENT VALUATION -- Municipal bonds are normally valued on the basis of
   valuations furnished by a pricing service. Taxable obligations, if any, for
   which price quotations are readily available are normally valued at the mean
   between the latest bid and asked prices. Futures contracts listed on the
   commodity exchanges are valued at closing settlement prices. Short-term
   obligations, maturing in sixty days or less, are valued at amortized cost,
   which approximates value. Investments for which valuations or market
   quotations are unavailable are valued at fair value using methods determined
   in good faith by or at the direction of the Trustees.

   B INCOME -- Interest income is determined on the basis of interest accrued,
   adjusted for amortization of premium or discount.

   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 and investment
   purposes. 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

                                       22
<Page>

   custodian fees are reported as a reduction of total expenses on the Statement
   of Operations.

   H USE OF ESTIMATES -- The preparation of the financial statements in
   conformity with accounting principles generally accepted in the United States
   of America 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.

   J INTERIM FINANCIAL STATEMENTS -- The interim financial statements relating
   to September 30, 2003 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. 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 sale of
   securities). For the six months ended September 30, 2003, the fee was
   equivalent to 0.45% (annualized) of the Portfolio's average net assets for
   such period and amounted to $469,611. 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, 2003, 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. At September
   30, 2003 the Portfolio had a balance outstanding pursuant to this line of
   credit of $700,000. The Portfolio did not have any significant borrowings or
   allocated fees during the six months ended September 30, 2003.

4  INVESTMENTS

   Purchases and sales of investments, other than U.S. Government securities and
   short-term obligations, aggregated $44,299,743 and $27,874,123 respectively,
   for the six months ended September 30, 2003.

5  FEDERAL INCOME TAX BASIS OF INVESTMENTS

   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at September 30, 2003, as computed on a federal income tax
   basis, were as follows:

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

                                       23
<Page>

   with these instruments is meaningful only when all related and offsetting
   transactions are considered.

   A summary of obligations under these financial instruments as of September
   30, 2003, is as follows:
