Cash Management Portfolio as of June 30, 1998
NOTES TO FINANCIAL STATEMENTS (Unaudited)
1 Significant Accounting Policies
------------------------------------------------------------------------------
Cash Management Portfolio (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 Security Valuation -- The Portfolio values investment securities utilizing
the amortized cost valuation technique permitted by Rule 2a-7 of the
Investment Company Act of 1940, pursuant to which the Portfolio must comply
with certain conditions. This technique involves initially valuing a portfolio
security at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium. It is the normal practice of the
Portfolio to hold portfolio securities to maturity and realize par value
unless such sale or other disposition is mandated by withdrawal requests or
other extraordinary circumstances.
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 has elected to be 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 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 Deferred Organization Expenses -- Costs incurred by the Portfolio in
connection with its organization are being amortized on the straight-line
basis over five years.
E 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 operating expenses on the Statement of Operations.
F Use of Estimates -- The preparation of 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.
G Other -- Investment transactions are accounted for on a trade date basis.
H Interim Financial Information -- The interim financial statements relating
to June 30, 1998 and for the six month 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 rate of 1/2 of 1% per annum of the Portfolio's average
daily net assets and amounted to $304,298 for the six months ended June 30,
1998. 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 of the officers and Trustees of the Portfolio are officers and
directors/trustees of the above organizations.

NOTES TO FINANCIAL STATEMENTS (Unaudited) CONT'D
3 Line of Credit
------------------------------------------------------------------------------
The Portfolio participates with other portfolios and funds managed by BMR or
EVM and its affiliates in a $100 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 participating 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.
4 Investments
------------------------------------------------------------------------------
Purchases and sales (including maturities) of investments, during the six
months ended June 30, 1998, exclusive of U.S. Government securities,
aggregated $455,763,326 and $434,622,741, respectively. Purchases and sales
(including maturities) of U.S. Government Agency securities aggregated
$273,732,705 and $338,489,942, respectively.
