SEI DAILY INCOME TRUST -- JULY 31, 1998 (UNAUDITED)



1.    ORGANIZATION
SEI Daily Income Trust (the "Trust") was organized as a Massachusetts business
trust under a Declara-tion of Trust dated March 15, 1982.
     The Trust is registered under the Investment Company Act of 1940, as
amended, as a diversified, open-end investment company with ten operational
Portfolios: the Money Market Portfolio, the Government Portfolio, the Government
II Portfolio, the Prime Obligation Portfolio, the Treasury Portfolio, the
Treasury II Portfolio (collectively the "Money Market Portfolios"), the
Short-Duration Government Portfolio (formerly the Short-Term Government
Portfolio), the Intermediate-Duration Government Portfolio (formerly the
Intermediate-Term Government Portfolio), the GNMA Portfolio, and the Corporate
Daily Income Portfolio (collectively the "Fixed Income Portfolios"). The
Portfolios' prospectus provides a description of each Portfolio's investment
objectives, policies and strategies. The assets of each portfolio are
segregated, and a shareholder's interest is limited to the Portfolio in which
shares are held.

2.    SIGNIFICANT ACCOUNTING POLICIES
The following is a summary of significant accounting policies followed by the
Portfolios.
     SECURITY VALUATION--Investment securities of the Money Market Portfolios
are stated at amortized cost which approximates market value. Under this
valuation method, purchase discounts and premiums are accreted and amortized
ratably to maturity and are included in interest income.
     Investment securities of the Fixed Income Portfolios which are listed on a
securities exchange for which market quotations are available are valued by an
independent pricing service at the last quoted sales price for such securities
on each business day. If there is no such reported sale, those securities for
which market quotations are readily available are valued at the most recent
quoted bid price. Unlisted securities for which market quotations are readily
available are valued at the most recently quoted price with estimates of such
values determined under certain market conditions using procedures determined in
good faith by the Board of Trustees. Debt obligations with sixty days or less
remaining until maturity may be valued at their amortized cost.
     FEDERAL INCOME TAXES--It is each Portfolio's intention to continue to
qualify as a regulated investment company and distribute all of its taxable
income and net capital gains. Accordingly, no provision for Federal income taxes
is required.
     RECLASSIFICATION OF COMPONENTS OF NET ASSETS--The timing and
characterization of certain income and capital gains distributions are
determined annually in accordance with federal tax regulations which may differ
from generally accepted accounting principles. As a result, net investment
income (loss) and net realized gain (loss) on investment transactions for the
reporting period may differ significantly from distributions during such period.
These book/tax differences may be temporary or permanent in nature. To the
extent these differences are permanent, they are charged or credited to
paid-in-capital or accumulated net realized gain, as appropriate, in the period
that the differences arise. Accordingly, the following permanent differences,
have been reclassified to/from the following accounts:

     NET ASSET VALUE PER SHARE--The net asset value per share is calculated on
each business day separately for each class of each Portfolio. In general, it is
computed by dividing the assets of each Portfolio, less its liabilities, by the
number of outstanding shares of the Portfolio.
     SECURITY TRANSACTIONS AND INVESTMENT INCOME--Security transactions are
accounted for on the trade date of the security purchase or sale. Costs used in
determining net realized capital gains and losses on the sale of securities are
those of the specific securities sold, adjusted for the accretion and
amortization of purchase discounts and premiums during the respective holding
period. Interest income is recorded on the accrual basis.



                                                                              27

NOTES TO FINANCIAL STATEMENTS
================================================================================
SEI DAILY INCOME TRUST -- JULY 31, 1998 (UNAUDITED)


     Purchase discounts and premiums on securities held in the "Fixed Income
Portfolios" are accreted and amortized over the life of each security and
recorded as interest income, using the effective interest method.
     REPURCHASE AGREEMENTS--Securities pledged as collateral for repurchase
agreements are held by each Portfolio's custodian bank until maturity of the
repurchase agreements. Provisions of the agreements and procedures adopted by
the Adviser ensure that the market value of the collateral, including accrued
interest thereon, is sufficient in the event of default by the counterparty. The
Portfolios also invest in tri-party repurchase agreements. Securities held as
collateral for tri-party repurchase agreements are maintained by the broker's
custodian bank in a segregated account until maturity of the repurchase
agreement. Provisions of the agreements ensure that the market value of the
collateral, including accrued interest thereon, is sufficient in the event of
default. If the counterparty defaults and the value of the collateral declines
or if the counterparty enters into an insolvency proceeding, realization of the
collateral by the Portfolio may be delayed or limited.
     EXPENSES--Expenses that are directly related to one of the Portfolios are
charged directly to that Portfolio. Other operating expenses of the Trust are
prorated to the Portfolios on the basis of relative net assets. Class specific
expenses, such as the distribution fees, are borne by that class. Income, other
expenses and realized and unrealized gains and losses of a Portfolio are
allocated to the respective class on the basis of the relative net asset value
each day.
     DISTRIBUTIONS TO SHAREHOLDERS--Distributions from net investment income are
declared on a daily basis and are payable on the first business day of the
following month. Any net realized capital gains on sales of securities for a
Portfolio are distributed to its shareholders at least annually.
     USE OF ESTIMATES--The financial statements have been prepared in accordance
with generally accepted accounting principles which require the use of
estimates. Actual results could differ from those estimates.

3.    TRANSACTIONS WITH AFFILIATES
SEI Investments Mutual Fund Services (the "Manager") provides management,
administrative and shareholder services to the Portfolios for an annual fee of
 .33% of the average daily net assets of the Money Market Portfolio, .19% each of
the average daily net assets of the Government II and Prime Obligation
Portfolios, .24% each of the average daily net assets of the Government,
Treasury and Treasury II Portfolios, .35% each of the average daily net assets
of the Short-Duration Government, Intermediate-Duration Government and Corporate
Daily Income Portfolios, and .32% of the GNMA Portfolio. However, the Manager
has agreed to waive its annual fee in an amount which limits total annual
expenses (including the annual management fee) of the following Portfolios to
the following amounts set forth in the Management Agreement (expressed as a
percentage of each Portfolio's daily net assets):

In the event that the total annual expenses of a Portfolio, after reflecting a
waiver of all fees by the Manager and Adviser, exceed the specified limitation,
the Manager has agreed to bear such excess. In addition to contractual specified
expense limits, the Manager may voluntarily waive a portion of its fee for both
the Money Market and Fixed Income Portfolios in order to limit the operating
expenses of the Portfolios.
    SEI Investments Distribution Co. ("the Distributor"), a wholly-owned
subsidiary of SEI Investments and a registered broker-dealer, acts as the
distributor of the shares of the Trust under the Distribution Agreements. The
Trust has adopted

================================================================================



plans under which firms, including the Distributor, that provide
shareholder and administrative services may receive compensation thereof. The
Class A, Class B, Class C, CNI Class and Sweep Classes each have shareholder
servicing plans (the "Shareholder Servicing Plans") which provide for servicing
fees payable to the Distributor of .25% of the average daily net assets
attributable to that particular class. For the Class A shares of the Money
Market Portfolios, Short-Duration Government Portfolio and Corporate Daily
Income Portfolio, no such fees were levied since the inception of the plan. In
addition to the Shareholder Servicing Plans, the Class B and Class C shares have
adopted administrative services plans that provide for administrative service
fees payable to the Distributor of up to .05% and .25%, respectively, of the
average daily net assets attributable to that class.
      The Treasury Portfolio Sweep Class and the Government Portfolio CNI Class
shares have adopted distribution plans ("the Plans") pursuant to Rule 12b-1
under the 1940 Act, in addition to the shareholder servicing plan. The Plans
provide for payments to the Distributor at an annual rate of .50% of a
Portfolio's average daily net assets attributable to CNI Class and Sweep Class
shares. These payments are characterized as "compensation," and are not directly
tied to expenses incurred by the Distributor; the payments the Distributor
receives during any year may therefore be higher or lower than its actual
expenses. These payments may be used to compensate CNI Class and Sweep Class
shareholders that provide distribution related services to their customers.
     Certain officers and/or Trustees of the Trust are also officers and/or
Directors of the Manager. The Trust pays each unaffiliated Trustee an annual fee
for attendance at quarterly, interim, and committee meetings. Compensation of
officers and affiliated Trustees is paid by the Manager.

or which securities are to be purchased or sold in the Portfolios.
