1 Significant Accounting Policies
-------------------------------------------
Investment Grade Income Portfolio (the Portfolio) is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-end,
management investment company. The Portfolio, which was organized as a trust
under the laws of the State of New York on February 28, 2000, seeks to
achieve current income and total return by investing in a portfolio
consisting primarily of fixed-income securities. 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 Valuations -- Debt securities (other than mortgage-backed pass
through securities and short-term obligations maturing in sixty days or
less), including listed securities and securities for which price quotations
are available and forward contracts, will normally be valued on the basis of
market valuations furnished by pricing services. Short-term obligations and
money market securities maturing in 60 days or less are valued at amortized
cost which approximates value. Non-U.S. dollar denominated short-term
obligations are valued at amortized cost as calculated in the base currency
and translated to U.S. dollars at the current exchange rate. 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 when required for federal
income tax purposes.
C Income Taxes -- The Portfolio has elected to be treated as a partnership for
United States 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 one of the Portfolio's investors is a regulated investment
company that invests all or substantially all of its 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. Withholding taxes on foreign dividends and
capital gains have been provided for in accordance with the Portfolio's
understanding of the applicable countries' tax rules and rates.
D Foreign Currency Translation -- Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases
and sales of foreign investment securities and income and expenses are
converted into U.S. dollars based upon currency exchange rates prevailing on
the respective dates of such transactions. Recognized gains or losses on
investment transactions attributable to changes in foreign currency exchange
rates are recorded for financial statement purposes as net realized gains and
losses on investments. That portion of unrealized gains and losses on
investments that results from fluctuations in foreign currency exchange rates
is not separately disclosed.
E 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.
F Expense Reduction -- Investors Bank & Trust Company (IBT) serves as custodian
to 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 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.
G Other -- Investment transactions are accounted for on a trade date basis.
Realized gains and losses are computed based on the specific identification
of the security sold.
H Interim Financial Statements -- The interim financial statements relating to
June 30, 2000 and for the period 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 computed at the monthly rate of 5/96 of 1% (0.625% annualized) of
the Portfolio's average daily net assets up to $300 million and 1/24 of 1%
(0.50% annualized) of average daily net assets of $300 million and more. For
the period ended June 30, 2000 the fee was equivalent to 0.61% of the
Portfolio's average net assets for such period and amounted to $207,551.
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 service 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 portion of their annual fees in accordance
with the terms of the Trustees Deferred Compensation Plan. For the period
ended June 30, 2000, no significant amounts have been deferred.
3 Investment Transactions
-------------------------------------------
Purchases and sales of investments, other than U.S. Government securities and
short-term obligations, aggregated $4,304,388 and $13,969,936, respectively.
Purchases and sales of U.S. Government agency securities aggregated
$21,028,344 and $20,089,919, respectively.
4 Federal Income Tax Basis of Investments
-------------------------------------------
The cost and unrealized appreciation (depreciation) in value of the
investments owned at June 30, 2000, as computed on a federal income tax
basis, were as follows:
<TABLE>
<S> <C>
AGGREGATE COST $104,193,027
------------------------------------------------------
Gross unrealized appreciation $ 313,546
Gross unrealized depreciation (3,196,503)
------------------------------------------------------
NET UNREALIZED DEPRECIATION $ (2,882,957)
------------------------------------------------------
</TABLE>
5 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. The Portfolio may temporarily borrow from the line of
credit to satisfy redemption requests or settle investment transactions.
Interest is charged to each portfolio or fund based on its borrowings at an
amount above 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 period ended June 30, 2000.
6 Transfer of Net Assets
-------------------------------------------
Prior to the opening of business on March 7, 2000, Eaton Vance Balanced Fund,
pursuant to an Agreement and Plan of Reorganization dated February 29, 2000,
contributed to the Portfolio net assets of $112,515,428, in exchange for an
interest therein, including $5,038,713 of net unrealized depreciation. The
transaction was structured for tax purposes to qualify as a tax free exchange
under the Internal Revenue Code.
