TAX-MANAGED VALUE PORTFOLIO AS OF APRIL 30, 2003

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1 Significant Accounting Policies
- -------------------------------------------
   Tax-Managed Value Portfolio (the Portfolio) is registered under the
   Investment Company Act of 1940, as amended, as an open-end management
   investment company. The Portfolio, which was organized as a trust under the
   laws of the State of New York on February 13, 2001, seeks to achieve
   long-term after-tax returns by investing in a diversified portfolio of value
   securities, primarily in well-established U.S. companies. The Declaration of
   Trust permits the Trustees to issue interests in the Portfolio. At April 30,
   2003, the Eaton Vance Tax-Managed Value Fund held approximately 93.1%
   interest in the Portfolio. The following is a summary of significant
   accounting policies consistently followed by the Portfolio 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 -- Marketable securities, including options, that are
   listed on foreign or U.S. securities exchanges are valued at closing sale
   prices on the exchange where such securities are principally traded.
   Marketable securities listed in the NASDAQ National Market System are valued
   at the NASDAQ official closing price. Unlisted or listed securities for which
   closing sale prices are not available are generally valued at the mean
   between the latest bid and asked prices. Futures positions on securities or
   currencies are generally valued at closing settlement prices. Short-term debt
   securities with a remaining maturity of 60 days or less are valued at
   amortized cost, which approximates fair value. Other fixed income and debt
   securities, including listed securities and securities for which price
   quotations are available, will normally be valued on the basis of valuations
   furnished by a pricing service. Over-the-counter options are normally valued
   at the mean between the latest bid and asked price. 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 -- Dividend income is recorded on the ex-dividend date for dividends
   received in cash and/or securities. However, if the ex-dividend date has
   passed, certain dividends from foreign securities are recorded as the
   Portfolio is informed of the ex-dividend date. Interest income is recorded on
   the accrual basis.

 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 on its share of taxable
   income. Since the Portfolio's investors include 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 investors each investor's distributive share of the
   Portfolio's net investment income, net realized capital gains, and any other
   items of income, gain, loss, deduction or credit.

 D Financial Futures Contract -- Upon entering 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 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 to hedge against
   anticipated future changes in price of current or anticipated Portfolio
   positions. Should prices move unexpectedly, the Portfolio may not achieve the
   anticipated benefits of the financial futures contracts and may realize a
   loss.

 E 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
   expenses on the Statement of Operations.

 F 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.

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

 H Interim Financial Statements -- The interim financial statements relating to
   April 30, 2003 and for the six months then ended have not been audited by

TAX-MANAGED VALUE PORTFOLIO AS OF APRIL 30, 2003

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) CONT'D

   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.
   Under the advisory agreement, BMR receives a monthly advisory fee in the
   amount of 13/240 of 1% (equal to 0.650% annually) of average daily net assets
   of the Portfolio up to $500 million, and at reduced rates as daily net assets
   exceed that level. For the six months ended April 30, 2003, the advisory fee
   amounted to $1,813,016. Except for 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 the investment
   adviser fee. Trustees of the Portfolio that are not affiliated with BMR 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 April 30, 2003, no significant amounts have been deferred.
   Certain officers and Trustees of the Portfolio are officers of the above
   organizations.

3 Investment Transactions
- -------------------------------------------
   Purchases and sales of investments, other than short-term obligations,
   aggregated $251,337,338 and $238,150,345 respectively, for the six months
   ended April 30, 2003.

4 Federal Income Tax Basis of Unrealized Appreciation (Depreciation)
- -------------------------------------------
   The cost and unrealized appreciation (depreciation) in value of the
   investments owned at April 30, 2003, as computed on a federal income tax
   basis, were as follows:

5 Financial Instruments
- -------------------------------------------
   The Portfolio may trade 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, forward foreign currency exchange contracts, and financial 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. The Portfolio
   did not have any open obligations under these financial instruments at
   April 30, 2003.

6 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 will be made by the Portfolio solely to
   facilitate the handling of unusual and/or unanticipated short-term cash
   requirements. Interest is charged to each participating portfolio or fund
   based on its borrowings at an amount above either the Eurodollar rate or
   Federal Funds rate. In addition, a fee computed at an annual rate of 0.10% on
   the daily unused portion of the line of credit is allocated among the
   participating portfolios and funds at the end of each quarter. The Portfolio
   did not have any significant borrowings or allocated fees during the six
   months ended April 30, 2003.
