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.

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. [CHART] Intermediate-term municipal bond yields were 86% of Treasury yields <Table> 5-Year AAA-rated General Obligation (GO) Bonds* 2.43% Taxable equivalent yield in 35.0% tax bracket 3.74% 5-Year Treasury Bond 2.82% </Table> Principal and interest payments of Treasury securities are guaranteed by U.S. government. * GO yields are a compilation of a representative variety of general obligations and are not necessarily representative of the Fund's yield. Statistics as of September 30, 2003. Past performance is no guarantee of future results: Source: Bloomberg, L.P. 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. *It is not possible to invest directly in an Index.

AHERN] William H. Ahern 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.

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: <Table> <Caption> SIX MONTHS ENDED SEPTEMBER 30, 2003 YEAR ENDED CLASS A (UNAUDITED) MARCH 31, 2003 ----------------------------------------------------------------------------------------------- Sales 1,622,393 5,791,770 Issued to shareholders electing to receive payments of distributions in Fund shares 117,143 205,741 Redemptions (1,809,225) (3,165,456) Exchange from Class B shares 218,183 351,348 ----------------------------------------------------------------------------------------------- Net increase 148,494 3,183,403 ----------------------------------------------------------------------------------------------- </Table> <Table> <Caption> SIX MONTHS ENDED SEPTEMBER 30, 2003 YEAR ENDED CLASS B (UNAUDITED) MARCH 31, 2003 ----------------------------------------------------------------------------------------------- Sales 1,113,766 2,964,288 Issued to shareholders electing to receive payments of distributions in Fund shares 25,515 33,384 Redemptions (457,354) (555,356) Exchange to Class A shares (218,087) (350,985) ----------------------------------------------------------------------------------------------- Net increase 463,840 2,091,331 ----------------------------------------------------------------------------------------------- </Table> <Table> <Caption> SIX MONTHS ENDED SEPTEMBER 30, 2003 YEAR ENDED CLASS C (UNAUDITED) MARCH 31, 2003 ----------------------------------------------------------------------------------------------- Sales 2,342,614 4,947,861 Issued to shareholders electing to receive payments of distributions in Fund shares 45,070 57,945 Redemptions (1,223,951) (2,262,121) ----------------------------------------------------------------------------------------------- Net increase 1,163,733 2,743,685 ----------------------------------------------------------------------------------------------- </Table> 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. 12 <Page> 8 SHAREHOLDER MEETING The Fund held a Special Meeting of Shareholders on June 6, 2003 to elect Trustees.

See notes to financial statements. 21 <Page> 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: <Table> AGGREGATE COST $ 205,305,103 ----------------------------------------------------------------- Gross unrealized appreciation $ 10,505,323 Gross unrealized depreciation (772,471) ----------------------------------------------------------------- NET UNREALIZED APPRECIATION $ 9,732,852 ----------------------------------------------------------------- </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 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: FUTURES CONTRACTS <Table> <Caption> EXPIRATION NET UNREALIZED DATE(S) CONTRACTS POSITION DEPRECIATION ------------------------------------------------------------------ 12/03 112 U.S. Treasury Bond Short (369,747) 12/03 101 U.S. Treasury Note Short (417,334) ------------------------------------------------------------------ $ (787,081) ------------------------------------------------------------------ </Table> At September 30, 2003, the Portfolio had sufficient cash and/or securities to cover margin requirements on open future contracts. 7 INTERESTHOLDER MEETING The Portfolio held a Special Meeting of Interestholders on June 6, 2003 to elect Trustees. The results of the vote were as follows: <Table> <Caption> INTEREST IN THE PORTFOLIO NOMINEE FOR TRUSTEE AFFIRMATIVE WITHHOLD -------------------------------------------------------------- Jessica M.
