The Trust files its complete schedule of portfolio holdings with the Securities
and Exchange Commission for the first and third quarters of each fiscal year on
Form N-Q within sixty days after the end of the period. The Trust's Forms N-Q
are available on the Commission's website at http://www.sec.gov, and may be
reviewed and copied at the Commission's Public Reference Room in Washington, DC.
Information on the operation of the Public Reference Room may be obtained by
calling 1-800-SEC-0330.

Since the Funds in SEI Daily Income Trust typically hold only fixed income
securities, they generally are not expected to hold securities for which they
may be required to vote proxies. Regardless, in light of the possibility that a
Fund could hold a security for which a proxy is voted, the Trust has adopted
proxy voting policies. A description of the policies and procedures that the
Trust uses to determine how to vote proxies relating to portfolio securities, as
well as information relating to how a Fund voted proxies relating to portfolio
securities during the most recent 12-month period ended June 30, is available
without charge (i) upon request, by calling 1-800-DIAL-SEI; and (ii) on the
Commission's website at http://www.sec.gov.

Percentages are based on Net Assets of $840,579 ($ Thousands).

*    Non-Income Producing.

(A)  The rate reported is the effective yield at time of purchase.

(B)  Securities are held in connection with a letter of credit issued by a major
     bank.

(C)  Floating Rate Instrument. The rate reflected on the Statement of
     Investments is the rate in effect on July 31, 2008. The demand and interest
     rate reset features give this security a shorter effective maturity date.

(D)  Securities sold within terms of a private placement memorandum, exempt from
     registration under Section 144A of the Securities Act of 1933, as amended,
     and may be sold only to dealers in that program or other "accredited
     investors." These securities have been determined to be liquid under
     guidelines established by the Board of Trustees.

(E)  Securities considered illiquid. The total value of such securities as of
     July 31, 2008 was $75,270 ($ Thousands) and represented 8.95% of Net
     Assets.

(F)  On October 17, 2007, due to deterioration in the market value of the assets
     Cheyne Finance LLC ("Cheyne"), provisions in the organizational documents
     of Cheyne were triggered that caused the notes issued by Cheyne to become
     immediately due and payable. Since no payments have been received, the
     Cheyne notes are in default.

(G)  The Fund has entered into a Capital Support Agreement ("agreement") with
     SEI Investments Company ("SEI") which provides that SEI will contribute
     capital to the Fund, up to a specified maximum amount, in the event that
     the Fund realizes a loss on any of these securities and such realized loss
     causes the Fund's net asset value as calculated using fair values to drop
     below $0.9950. As of July 31, 2008, the fair value of the agreement was
     $1,998 ($ Thousands).

(H)  The value shown is the fair value as of July 31, 2008. Please refer to Note
     10 for the amortized cost value as of July 31, 2008.

(I)  These securities are considered restricted. The total value of such
     securities as of July 31, 2008 was $75,270 ($ Thousands) and represented
     8.95% of Net Assets.

(J)  Tri-Party Repurchase Agreement.

(K)  Cheyne Finance LLC ("Cheyne") was a structured investment vehicle that
     defaulted on its notes in October, 2007. Receivers were appointed with the
     responsibility to liquidate the assets of the structure and deliver the
     proceeds to the noteholders. As an alternative to accepting the proceeds
     from the auction of the underlying collateral, senior noteholders of
     Cheyne, including the Fund, were given the opportunity to exchange all of
     their existing senior notes for certain notes issued by a newly formed
     entity, Gryphon Funding Limited ("Gryphon"). The Fund elected to exchange
     its Cheyne senior notes for Gryphon notes. As part of the restructuring
     transaction, Gryphon, in its capacity as the holder of the senior notes in
     Cheyne following its formation, was deemed to receive a cash distribution
     from Cheyne following the auction. Gryphon then used this cash to purchase
     from a third party a significant portion of the assets formerly held by
     Cheyne. Following this transaction, Gryphon distributed the senior notes
     in Cheyne back to the original senior noteholders, which included the
     Fund. The Cheyne entity continues to exist following the restructuring,
     holding a small residual amount of cash to satisfy known and unknown
     liabilities. As a result, the Fund continues to hold its original senior
     notes in Cheyne as well as the newly issued Gryphon notes. This
     restructuring transaction was effected during July 2008.

(L)  Notes issued by Gryphon Funding LLC were received by the Fund in connection
     with a restructuring of Cheyne Finance LLC (Cheyne) on July 23, 2008.

Percentages are based on Net Assets of $4,768,724 ($ Thousands).

*    Non-Income Producing.

(A)  The rate reported is the effective yield at time of purchase.

(B)  Securities are held in connection with a letter of credit issued by a major
     bank.

(C)  Floating Rate Instrument. The rate reflected on the Schedule of Investments
     is the rate in effect on July 31, 2008. The demand and interest rate reset
     features give this security a shorter effective maturity date.

(D)  Securities considered illiquid. The total value of such securities as of
     July 31, 2008 was $535,315 ($ Thousands) and represented 11.23% of Net
     Assets.

(E)  These securities are considered restricted. The total value of such
     securities as of July 31, 2008 was $535,315 ($ Thousands) and represented
     11.23% of Net Assets.

(F)  Securities sold within terms of a private placement memorandum, exempt from
     registration under Section 144A of the Securities Act of 1933, as amended,
     and may be sold only to dealers in that program or other "accredited
     investors." These securities have been determined to be liquid under
     guidelines established by the Board of Trustees.

(G)  On October 17, 2007, due to deterioration in the market value of the assets
     Cheyne Finance LLC ("Cheyne"), provisions in the organizational documents
     of Cheyne were triggered that caused the notes issued by Cheyne to become
     immediately due and payable. Since no payments have been received, the
     Cheyne notes are in default.

(H)  The Fund has entered into a Capital Support Agreement ("agreement") with
     SEI Investments Company ("SEI") which provides that SEI will contribute
     capital to the Fund, up to a specified maximum amount, in the event that
     the Fund realizes a loss on any of these securities and such realized loss
     causes the Fund's net asset value as calculated using fair values to drop
     below $0.9975. As of July 31, 2008, the fair value of the agreement was
     $82,424 ($ Thousands).

(I)  The value shown is the fair value as of July 31, 2008. Please refer to Note
     10 for the amortized cost value as of July 31, 2008.

(J)  On January 18, 2008, due to deterioration in the market value of the assets
     Stanfield Victoria Finance, LLC ("Victoria"), provisions in the
     organizational documents of Victoria were triggered that caused the notes
     issued by Victoria to become immediately due and payable. Since no payments
     have been received, the Victoria notes are in default. Since that time,
     this security's valuation has been determined in accordance with fair value
     for purposes of calculating the Fund's "mark-to-market" net asset value. As
     of the time of this filing, there is a material difference between the fair
     value of this security and its amortized cost.

(K)  Tri-Party Repurchase Agreement.

(L)  Cheyne Finance LLC ("Cheyne") was a structured investment vehicle that
     defaulted on its notes in October, 2007. Receivers were appointed with the
     responsibility to liquidate the assets of the structure and deliver the
     proceeds to the noteholders. As an alternative to accepting the proceeds
     from the auction of the underlying collateral, senior noteholders of
     Cheyne, including the Fund, were given the opportunity to exchange all of
     their existing senior notes for certain notes issued by a newly formed
     entity, Gryphon Funding Limited ("Gryphon"). The Fund elected to exchange
     its Cheyne senior notes for Gryphon notes. As part of the restructuring
     transaction, Gryphon, in its capacity as the holder of the senior notes in
     Cheyne following its formation, was deemed to receive a cash distribution
     from Cheyne following the auction. Gryphon then used this cash to purchase
     from a third party a significant portion of the assets formerly held by
     Cheyne. Following this transaction, Gryphon distributed the senior notes
     in Cheyne back to the original senior noteholders, which included the
     Fund. The Cheyne entity continues to exist following the restructuring,
     holding a small residual amount of cash to satisfy known and unknown
     liabilities. As a result, the Fund continues to hold its original senior
     notes in Cheyne as well as the newly issued Gryphon notes. This
     restructuring transaction was effected during July 2008.

(M)  Notes issued by Gryphon Funding LLC were received by the Fund in connection
     with a restructuring of Cheyne Finance LLC (Cheyne) on July 23, 2008.

(3)  The Distributor has voluntarily agreed to waive and reduce its fee and/or
     reimburse certain expenses of the Treasury Fund in order to limit the
     one-day net income yield of the Fund to not less than 0.15% of the Treasury
     Fund's average daily net assets of the Sweep Class Shares. Had these
     waivers been excluded the ratio would have been 0.95%.

NOTES TO FINANCIAL STATEMENTS

Notes to Financial Statements (Unaudited)

1. ORGANIZATION

SEI Daily Income Trust (the "Trust") was organized as a Massachusetts business
trust under a Declaration 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 Funds: the Money
Market, Government, Government II, Prime Obligation, Treasury, Treasury II (each
a "Fund," collectively the "Money Market Funds"), the Short-Duration Government,
Intermediate-Duration Government, GNMA, and Ultra Short Bond (each a "Fund,"
collectively the "Fixed Income Funds"). The Money Market, Government, Government
II, Prime Obligation, Treasury, Treasury II, Short-Duration Government,
Intermediate-Duration Government, and GNMA Funds seek to preserve principal
value and maintain a high degree of liquidity while providing current income.
The Ultra Short Bond Fund seeks to provide higher current income than that
typically offered by a money market fund while maintaining a high degree of
liquidity and a correspondingly higher risk of principal volatility. The assets
of each Fund are segregated, and a shareholder's interest is limited to the Fund
in which shares are held.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the
Funds.

USE OF ESTIMATES -- The preparation of financial statements, in conformity with
U.S. generally accepted accounting principles, requires management to make
estimates and assumptions that affect the reported amount of assets and
liabilities and disclosure of contingent assets at the date of the financial
statements, and the reported results of operations during the reporting period.
Actual results could differ from those estimates.

SECURITY VALUATION -- Investment securities of the Money Market Funds, except
those securities which are covered by the Capital Support Agreement, 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. Refer to Note 10 for a discussion of the
Capital Support Agreement entered into by the Money Market Fund and the Prime
Obligation Fund.

Investment securities of the Fixed Income Funds listed on a securities exchange,
market or automated quotation system for which quotations are readily available
are valued at the last quoted sale price on the primary exchange or market on
which they are traded, or, if there is no such reported sale, at the most recent
quoted bid price. If available, debt securities are priced based upon valuations
provided by independent, third-party pricing agents. Such values generally
reflect the last reported sales price if the security is actively traded. The
third-party pricing agents may also value debt securities at an evaluated bid
price by employing methodologies that utilize actual market transactions,
broker-supplied valuations, or other methodologies designed to identify the
market value for such securities. Debt obligations with remaining maturities of
sixty days or less may be valued at their amortized cost, which approximates
market value. Prices for most securities held in the Funds are provided daily by
recognized independent pricing agents. If a security price cannot be obtained
from an independent, third-party pricing agent, the Funds seek to obtain a bid
price from at least one independent broker.

Securities for which market prices are not "readily available" are valued in
accordance with Fair Value Procedures established by the Funds' Board of
Trustees. The Funds' Fair Value Procedures are implemented through a Fair Value
Committee (the "Committee") designated by the Funds' Board of Trustees. Some of
the more common reasons that may necessitate that a security be valued using
Fair Value Procedures include: the security's trading has been halted or
suspended; the security has been de-listed from a national exchange; the
security's primary trading market is temporarily closed at a time when under
normal conditions it would be open; or the security's primary pricing source is
not able or willing to provide a price. When a security is valued in accordance
with the Fair Value Procedures, the Committee will determine the value after
taking into consideration relevant information reasonably available to the
Committee.

Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 157, Fair Value Measurements ("FAS 157"), is effective for the Fund's
financial statements issued after December 31, 2007. In accordance with FAS 157,
fair value is defined as the price that the Fund would receive upon selling an
investment in a timely transaction to an independent buyer in the principal or
most advantageous market of the investment. FAS 157 established a three-tier
hierarchy to maximize the use of the observable market data and minimize the use
of unobservable inputs and to establish classification of the fair value
measurements for disclosure purposes. Inputs refer broadly to the assumptions
that market participants would use in pricing an asset. Inputs may be observable
or unobservable. Observable inputs are inputs that reflect the assumptions
market participants would use in pricing the asset or liability developed based
on market data obtained from sources independent of the reporting entity.
Unobservable inputs are inputs that reflect the reporting entity's own
assumptions about the assumptions market participants would use in pricing the
asset or liability developed based on the best information available in the
circumstances.

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

The three-tier hierarchy of inputs is summarized in the three broad Levels
listed below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for
similar investments, interest rates, prepayment speeds, credit risks, etc.)

Level 3 - significant unobservable inputs (including the Fund's own assumptions
in determining the fair value of investments)

The valuation techniques used by the Fund to measure fair value in accordance
with FAS 157 during the six months ended July 31, 2008 maximized the use of
observable inputs and minimized the use of unobservable inputs.

The following is a summary of the inputs used as of July 31, 2008 in valuing the
Fund's investments in accordance with FAS 157 carried at value ($ Thousands):

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. Purchase discounts and
premiums on securities held in the Fixed Income Funds are accreted and amortized
over the life of each security. Paydown gains and losses are classified as
interest income.

REPURCHASE AGREEMENTS -- Securities pledged as collateral for repurchase
agreements are held by each Fund's custodian bank until maturity of the
repurchase agreements. Provisions of the agreements and the Trust's policies
ensure that the market value of the collateral, including accrued interest
thereon, is sufficient in the event of default by the counterparty. The Funds
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 a Fund may be delayed or limited.

FUTURES CONTRACTS -- The Fixed Income Funds utilized futures contracts during
the six months ended July 31, 2008. The Funds' investment in these futures
contracts is designed to enable the Funds to more closely approximate the
performance of their benchmark indices.

Initial margin deposits of cash or securities are made upon entering into
futures contracts. The contracts are "marked-to-market" daily and the resulting
changes in value are accounted for as unrealized gains and losses. Variation
margin payments are paid or received, depending upon whether unrealized losses
or gains are incurred. When the contract is closed, the Funds record a realized
gain or loss equal to the difference between the proceeds from (or cost of) the
closing transaction and the amount invested in the contract.

Risks related to futures contracts include the possibility that there may not be
a liquid market for the contracts, that the changes in the value of the contract
may not directly correlate with changes in the value of the underlying
securities, and that the counterparty to a contract may default on its
obligation to perform. The notional amount presented in the Schedules of
Investments in the Fixed Income Funds represents the Fund's total exposure in
such contracts, whereas only the net unrealized appreciation (depreciation) is
reflected in the Fund's net assets.

SWAP AGREEMENTS -- A swap agreement is a two-party contract under which an
agreement is made to exchange returns from predetermined investments or
instruments, including a particular interest rate, foreign currency, or "basket"
of securities representing a particular index. Credit-default swaps involve the
periodic payment by the Fund or counterparty of interest based on a specified
rate multiplied by a notional amount assigned to an underlying debt instrument
or group of debt instruments in exchange for the assumption of credit risk on
the same instruments. In the event of a credit event, usually in the form of a
credit rating downgrade, the party receiving periodic payments (i.e. floating
rate payer) must pay the other party (i.e. fixed rate payer) an amount equal to
the outstanding principal of the downgraded debt instrument. Total return swaps
allow an investor to benefit from the cash flow without ever actually owning the
underlying security. The receiver must pay any decline in value to the payer at
the end of the total return swaps. However, the investor does not need to make a
payment if there is no decline in price. Payments can be made on various
indices, bonds (i.e. mortgage backed securities, bank debt and corporate), loans
or commodities. The value of a total return swap is equal to the change in value
of the underlying asset versus the accrued income payment based on LIBOR (London
Interbank Offered Rate) or some other form of index on the notional amount.
Interest rate swaps involve the exchange by a Fund with another party of their
respective commitments to pay or receive interest (e.g., an exchange of floating
rate payments for fixed rate payments) with respect to a notional amount of
principal to manage the Fund's exposure to interest rates. Payments received or
made are recorded as realized gains or losses. The Fund could be exposed to
credit or market risk due to unfavorable changes in the fluctuation of interest
rates or if the counterparty defaults on its obligation to perform. Risk of loss
may exceed amounts recognized on the statement of assets and liabilities. In
connection with swap agreements, securities may be set aside as collateral by
the Fund's custodian. A Fund may enter into swap agreements in order to, among
other things, change the maturity or duration of the investment portfolio;
protect the Fund's value from changes in interest rates; or expose a Fund to a
different security or market.

Swaps are marked-to-market daily based upon quotations from market makers and
the resulting changes in market values, if any, are recorded as unrealized gains
or losses in the Statement of Operations. Net payments of interest are recorded
as realized gains or losses.

Entering into swap agreements involves, to varying degrees, elements of credit
and market risk in excess of the amounts recognized on the Schedule of
Investments or the Statement of Assets and Liabilities. Such risks involve the
possibility that there will be no liquid market for these agreements, that the
counterparty to the agreement may default on its obligation to perform and that
there may be unfavorable changes in the fluctuation of interest rates. Risks
also arise from potential losses from adverse market movements. There were no
swap agreements as of July 31, 2008.

TBA PURCHASE COMMITMENTS -- The Funds may engage in "to be announced" ("TBA")
purchase commitments to purchase securities for a fixed price at a future date.
TBA purchase commitments may be considered securities and involve a risk of loss
if the value of the security to be purchased declines prior to settlement date,
which risk is in addition to the risk of decline in the value of a Fund's other
assets. Unsettled TBA purchase commitments are valued at the current market
value of the underlying securities, according to the procedures described under
"Security Valuation" above.

COLLATERALIZED DEBT OBLIGATIONS -- The Funds may invest in collateralized debt
obligations ("CDOs"), which include collateralized loan obligations ("CLOs") and
other similarly structured securities. CLOs are a type of asset-backed
securities. A CLO is a trust typically collateralized by a pool of loans, which
may include, among others, domestic and foreign senior secured loans, senior
unsecured loans, and subordinate corporate loans, including loans that may be
rated below investment grade or equivalent unrated loans. CDOs may charge
management fees and administrative expenses.

For CDOs, the cashflows from the trust are split into two or more portions,
called tranches, varying in risk and yield. The riskiest portion is the "equity"
tranche which bears the bulk of defaults from the bonds

NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

or loans in the trust and serves to protect the other, more senior tranches
from default in all but the most severe circumstances. Since it is partially
protected from defaults, a senior tranche from a CDO trust typically has a
higher rating and lower yield than their underlying securities, and can be rated
investment grade. Despite the protection from the equity tranche, CDO tranches
can experience substantial losses due to actual defaults, increased sensitivity
to defaults due to collateral default and disappearance of protecting tranches,
market anticipation of defaults, as well as aversion to CDO securities as a
class.

The risks of an investment in a CDO depend largely on the type of the collateral
securities and the class of the CDO in which a Fund invests. Normally, CLOs and
other CDOs are privately offered and sold, and thus, are not registered under
the securities laws. As a result, investments in CDOs may be characterized by
the Funds as illiquid securities; however, an active dealer market may exist for
CDOs allowing a CDO to qualify for Rule 144A transactions. In addition to the
normal risks associated with fixed income securities (e.g., interest rate risk
and default risk), CDOs carry additional risks including, but not limited to:
(i) the possibility that distributions from collateral securities will not be
adequate to make interest or other payments; (ii) the quality of the collateral
may decline in value or default; (iii) the Funds may invest in CDOs that are
subordinate to other classes; and (iv) the complex structure of the security may
not be fully understood at the time of investment and may produce disputes with
the issuer or unexpected investment results.

ILLIQUID SECURITIES -- A security is considered illiquid if it cannot be sold or
disposed of in the ordinary course of business within seven days or less for its
approximate carrying value on the books of the Funds. Valuations of illiquid
securities may differ significantly from the values that would have been used
had an active market value for these securities existed.

RESTRICTED SECURITIES -- At July 31, 2008, the following Funds owned private
placement investments that were purchased through private offerings or acquired
through initial public offerings and cannot be sold without prior registration
under the Securities Act of 1933 or pursuant to an exemption therefrom. In
addition, the Funds have generally agreed to further restrictions on the
disposition of certain holdings as set forth in various agreements entered into
in connection with the purchase of these investments. These investments are
valued at amortized cost as determined in accordance with the procedures
approved by the Board of Trustees.

The acquisition dates of these investments, along with their cost and values at
July 31, 2008, were as follows:

CLASSES -- Class-specific expenses are borne by that class of shares. Income,
realized and unrealized gains/losses and non-class-specific expenses are
allocated to the respective class on the basis of relative daily net assets.

EXPENSES -- Expenses that are directly related to one of the Funds are charged
directly to that Fund. Other operating expenses of the Trust, which are not
directly associated to a specific Fund, are prorated to the Funds on the basis
of relative daily net assets.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends and distributions to
shareholders, which are determined in accordance with Federal tax regulations,
are recorded on the ex-dividend date. Dividends 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
Fund are distributed to its shareholders at least annually.

*    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 sweep class shareholders
     who provide distribution-related services to their customers.

The Distributor has voluntarily waived all or a portion of the shareholder
servicing fees for Class A of each fund, except for the GNMA Fund, since
inception of the plan. Such waivers are voluntary and may be discontinued at any
time. For Classes B, C, and H, the shareholder servicing fees and the
administrative service fees are shown combined as "Administrative & Shareholder
Servicing Fees" in the Statement of Operations. The Distributor has voluntarily
agreed to waive and reduce its fee and/or reimburse certain expenses of the
Treasury Fund in order to limit the one-day net income yield of the Fund to not
less than 0.15% of the Treasury Fund's average daily net assets of the Sweep
Class Shares. There were $16,277 in waivers for the six month period ended
July 31, 2008.

Certain officers and Trustees of the Trust are also officers and/or Trustees of
the Administrator or the adviser. The Trust pays each unaffiliated Trustee an
annual fee for attendance at quarterly, interim, and committee meetings. The
Administrator or the adviser pays compensation of officers and affiliated
Trustees.

The services provided by the Chief Compliance Officer ("CCO") and his staff,
whom are employees of the Administrator, are paid for by the Trust as incurred.
The services include regulatory oversight of the Trust's Advisors and service
providers as required by SEC regulations. The CCO's services have been approved
by and are reviewed by the Board.

CAPITAL SUPPORT AGREEMENT -- The Money Market Fund and Prime Obligation Fund
have entered into a Capital Support Agreement with SEI Investments Company
("SEI"). Please see Note 10 for more information.

4. INVESTMENT ADVISORY AND CUSTODIAN AGREEMENTS

SEI Investments Management Corporation ("SIMC") serves as each Fund's investment
adviser and "manager of managers" under an investment advisory agreement
approved by the shareholders of each Fund. For its services, SIMC receives an
annual fee equal to .075% on the first $500 million of net assets and .02% on
the net assets in excess of $500 million for the Money Market Funds. The fee
will be calculated based on the combined assets of the Money Market Funds. SIMC
also receives an annual fee equal to .10% on the first $500 million of net
assets, .075% of net assets between $500 million and $1 billion and .05% on the
net assets in excess of $1 billion for the Short-Duration Government,
Intermediate-Duration Government and GNMA Funds. The fee will be calculated
based on the combined assets of the Funds listed above. SIMC also receives an
annual fee equal to .10% on the first $500 million of net assets, .075% of net
assets between $500 million and $1 billion and .05% on the net assets in excess
of $1 billion for the Ultra Short Bond Fund. The fee will be calculated based on
the net assets of the Ultra Short Bond Fund.

Pursuant to the "manager of managers" structure, the Board of Trustees approved
Columbia Management Advisors, LLC (formerly Banc of America Capital Management,
LLC) as each Money Market Fund's investment sub-adviser under an investment
sub-advisory agreement approved by the shareholders of each Fund. For its
services to the Money Market Funds, the sub-adviser is entitled to receive a fee
paid directly by SIMC.

Wellington Management Company, LLP ("Wellington LLP") serves as sub-adviser to
the Fixed Income Funds under an investment sub-advisory agreement approved by
the shareholders of each Fund. For its services to the Funds, Wellington LLP is
entitled to receive a fee paid directly by SIMC.

role in determining the investment policies of the Funds or which securities are
to be purchased or sold in the Funds.

6. FEDERAL TAX INFORMATION

It is each Fund's intention to continue to qualify as a regulated investment
company for Federal income tax purposes and distribute all of its taxable income
(including 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 gain distributions are determined annually in
accordance with Federal tax regulations which may differ from accounting
principles generally accepted in the United States. As a result, net investment
income (loss) and net realized gain (loss) on investment transactions for the
reporting period may differ 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, undistributed net investment income, or accumulated net realized gain,
as appropriate, in the periods that the differences arise.

The tax character of dividends and distributions during the last two fiscal
years was as follows:



                                                Long-term

For Federal income tax purposes, capital loss carryforwards may be carried
forward and applied against future capital gains. It is the Funds' intent that
they will not distribute any realized gain distributions until the carryforwards
have been offset or expired.

During the year ended January 31, 2008, the Short-Duration Government Fund and
Intermediate-Duration Government Fund utilized $2,433,815 and $1,318,946,
respectively, of capital loss carryforwards, to offset capital gains.

At July 31, 2008, the Money Market Funds' (excluding the Money Market Fund and
Prime Obligation Fund) cost of securities for Federal income tax purposes
approximates the cost located in the Statements of Assets and Liabilities.

The Federal tax cost and aggregate gross unrealized appreciation and
depreciation on investments held by the Money Market Fund, Prime Obligation Fund
and Fixed Income Funds at July 31, 2008, were as follows:

7. INVESTMENT RISKS

In the normal course of business, the Funds enter into contracts that provide
general indemnifications by the Fund to the counterparty to the contract. The
Funds' maximum exposure under these arrangements is dependent on future claims
that may be made against the Funds and, therefore, cannot be established;
however, based on experience, the risk of loss from such claim is considered
remote.

Investments in structured securities (such as those issued by Structured
Investment Vehicles, or "SIVs") which are collateralized by residential real
estate mortgages are subject to certain credit and liquidity risks. When market
conditions result in an increase in default rates of the underlying mortgages
and the foreclosure values of underlying real estate properties are materially
below the outstanding amount of these underlying mortgages, collection of
accrued interest and principal on these investments may be doubtful. Such market
conditions may significantly impair the value of these investments resulting in
a lack of correlation between their credit ratings and values.

8. OTHER

The Board approved a 5 for 1 reverse share split in the Ultra Short Bond Fund.
The reverse share split occurred on May 6, 2005. This Fund is designed to be a
low tracking error fund. The Fund experienced excess tracking error due to the
impact of rounding on the Fund's net asset value ("NAV"). The reverse share
split resulted in a higher NAV for the Fund, thus decreasing the level of
tracking error resulting from NAV rounding. The per share information included
in the financial highlights for all periods prior to the reverse share split
have been adjusted to properly reflect the effects of the reverse share spilt on
a retroactive basis.

9. NEW ACCOUNTING PRONOUNCEMENT

In March 2008, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 161, DISCLOSURES ABOUT DERIVATIVE
INSTRUMENTS AND HEDGING ACTIVITIES. SFAS No. 161 is effective for fiscal years
and interim periods beginning after November 15, 2008. SFAS No. 161 requires
enhanced disclosures about the Funds' derivative and hedging activities,
including how such activities are accounted for and their effect on the Funds'
financial position, performance, and cash flows.

10. CAPITAL SUPPORT AGREEMENT

On November 8, 2007, the Money Market and Prime Obligation Funds each entered
into a Capital Support Agreement with SEI, which is the parent company of SIMC.
The Capital Support Agreements require SEI to commit capital to the Funds,
subject to the aggregate limit of $3 million and $126 million for the Money
Market Fund and Prime Obligation Fund, respectively, if a Fund realizes payments
or sales proceeds from specified securities ("Eligible Notes") held by the Funds
which are less than the amortized cost of such securities and such loss causes
the Fund's mark-to-market net asset value to drop below $0.9950 for the Money
Market Fund or $0.9975 for the Prime Obligation Fund. The mark-to-market net
asset value is calculated using the market value of all securities in the Money
Market and Prime Obligation Funds. The net asset value in the financial
statements is calculated using the amortized cost for all securities except the
Eligible Notes.The Eligible Notes held in the Funds on July 31, 2008 are
footnoted on the Schedule of Investments. On February 15, 2008, the Agreement
for the Prime Obligation Fund was amended to increase the maximum contribution
amount to $150 million. Upon the sale or other disposition of an Eligible Note,
the amount of required capital commitment would be the least of the following
amounts: (i) the amount, if any, by which the amortized cost of the Eligible
Note exceeds the amount realized from the sale or other disposition of the
security; (ii) the amount, if any, necessary to restore the net asset value per
share of the Fund to $0.9950 for the Money Market Fund or $0.9975 for the Prime
Obligation Fund, or (iii) the remaining amount of the aggregate limit of the
Capital Support Agreement, taking into account all prior contributions. SEI's
obligations under the Agreements are supported by a Letter of Credit issued by a
bank having a First Tier credit rating and, in the case of the Prime Obligation
Fund, cash held in a segregated account in the amounts of $3 million and $150
million for the Money Market and Prime Obligation Funds, respectively. The Funds
will draw on the Letter of Credit or the segregated account in the event that
SEI fails to make a cash contribution when due under the Agreement.

The Funds will sell the Eligible Notes (i) promptly following any change in the
Letter of Credit provider's short term credit ratings such that the Letter of
Credit provider's obligations no longer qualify as First Tier Securities as
defined in paragraph (a)(12) of Rule 2a-7, or (ii) on the business day
immediately prior to the termination date of the Agreement; provided that the
Funds are not required to complete any such sale if the amount the Funds expect
to receive would not result in the payment of a Capital Contribution, or, with
respect to an event described in (i) above, if SEI substitutes an obligation or
credit support that satisfies the requirement of a First Tier Security within
fifteen (15) calendar days from the occurrence of such event and, during such 15
day period, the Letter of Credit provider's obligations continue to qualify as
Second Tier Securities under paragraph (a)(22) of Rule 2a-7. The termination
date of the Agreement is November 6, 2008, although that date may be extended
upon agreement of SEI and the Funds, subject to the prior approval of the staff
of the U.S. Securities and Exchange Commission.

11. SUBSEQUENT EVENT

As of September 26, 2008, the Capital Support Agreement is valued at $92,368,994
for the Prime Obligation Fund.

Subsequent to July 31, 2008, an affiliate of SIMC purchased from the Money
Market Fund all of the notes issued by Cheyne Finance, LLC and Gryphon Funding
Limited that were held by the Fund. This trancaction was effected pursuant to
Rule 17a-9 under the Investment Company Act of 1940 (the "Act"), which permits
an affiliate to purchase a security from a money market fund if that security is
no longer an Eligible Security pursuant to Rule 2a-7 under the Act. Cheyne
and Gryphon were not Eligible Securities at the time of the transaction.

SEI DAILY INCOME TRUST -- JULY 31, 2008

Disclosure of Fund Expenses (Unaudited)

All mutual funds have operating expenses. As a shareholder of a Fund, your
investment is affected by these ongoing costs, which include (among others)
costs for portfolio management, administrative services, and shareholder reports
like this one. It is important for you to understand the impact of these costs
on your investment returns.

Operating expenses such as these are deducted from the Fund's gross income and
directly reduce your final investment return. These expenses are expressed as a
percentage of the Fund's average net assets; this percentage is known as the
Fund's expense ratio.

The following examples use the expense ratio and are intended to help you
understand the ongoing costs (in dollars) of investing in your Fund and to
compare these costs with those of other mutual funds. The examples are based on
an investment of $1,000 made at the beginning of the period shown and held for
the entire period.

The table on the next page illustrates your Fund's costs in two ways:

- -    ACTUAL FUND RETURN. This section helps you to estimate the actual expenses
     that your Fund incurred over the period. The "Expenses Paid During Period"
     column shows the actual dollar expense cost incurred by a $1,000 investment
     in the Fund, and the "Ending Account Value" number is derived from
     deducting that expense cost from the fund's gross investment return.

You can use this information, together with the actual amount you invested in
the fund, to estimate the expenses your Fund incurred over that period. Simply
divide your actual starting account value by $1,000 to arrive at a ratio (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply that
ratio by the number shown for your Fund under "Expenses Paid During Period."

- -    HYPOTHETICAL 5% RETURN. This section helps you compare your Fund's costs
     with those of other mutual funds. It assumes that the fund had an annual 5%
     return before expenses during the year, but that the expense ratio (Column
     3) is unchanged. This example is useful in making comparisons because the
     Securities and Exchange Commission requires all mutual funds to make this
     5% calculation. You can assess your Fund's comparative cost by comparing
     the hypothetical result for your Fund in the "Expense Paid During Period"
     column with those that appear in the same charts in the shareholder reports
     for other funds.

NOTE: Because the return is set at 5% for comparison purposes -- NOT your Fund's
actual return -- the account values shown do not apply to your specific
investment.

          SEI Daily Income Trust / Semi-Annual Report / July 31, 2008


                                       46



Board of Trustees Considerations in Approving the Continuation of the Funds'
Advisory and Sub-Advisory Agreements (Unaudited)

SEI Daily Income Trust (the "Trust") and SEI Investments Management Corporation
("SIMC") have entered into an investment advisory agreement (the "Advisory
Agreement"). Pursuant to the Advisory Agreement, SIMC oversees the investment
advisory services provided to the series of the Trust (the "Funds") and may
manage the cash portion of the Funds' assets. Pursuant to separate sub-advisory
agreements (the "Sub-Advisory Agreements" and, together with the Advisory
Agreement, the "Investment Advisory Agreements") with SIMC, and under the
supervision of SIMC and the Trust's Board of Trustees (the "Board"), the
Sub-Advisers are responsible for the day-to-day investment management of all or
a discrete portion of the assets of the Funds. The Sub-Advisers also are
responsible for managing their employees who provide services to these Funds.
The Sub-Advisers are selected based primarily upon the research and
recommendations of SIMC, which evaluates quantitatively and qualitatively the
Sub-Advisers' skills and investment results in managing assets for specific
asset classes, investment styles and strategies.

The Investment Company Act of 1940, as amended (the "1940 Act") requires that
the initial approval of, as well as the continuation of, the Funds' Investment
Advisory Agreements must be specifically approved: (i) by the vote of the Board
of Trustees or by a vote of the shareholders of the Funds; and (ii) by the vote
of a majority of the Trustees who are not parties to the Investment Advisory
Agreements or "interested persons" of any party (the "Independent Trustees"),
cast in person at a meeting called for the purpose of voting on such approval.
In connection with their consideration of such approvals, the Funds' Trustees
must request and evaluate, and SIMC and the Sub-Advisers are required to
furnish, such information as may be reasonably necessary to evaluate the terms
of the Investment Advisory Agreements. In addition, the Securities and Exchange
Commission ("SEC") takes the position that, as part of their fiduciary duties
with respect to a mutual fund's fees, mutual fund boards are required to
evaluate the material factors applicable to a decision to approve an Investment
Advisory Agreement.

Consistent with these responsibilities, the Trust's Board of Trustees calls and
holds meetings each year that are dedicated to considering whether to renew the
Investment Advisory Agreements between the Trust and SIMC and SIMC and the
Sub-Advisers with respect to the Funds of the Trust. In preparation for these
meetings, the Board requests and reviews a wide variety of materials provided by
SIMC and the Sub-Advisers, including information about SIMC's and the
Sub-Advisers' affiliates, personnel and operations. The Board also receives
extensive data provided by third parties. This information is in addition to the
detailed information about the Funds that the Board reviews during the course of
each year, including information that relates to Fund operations and Fund
performance. The Trustees also receive a memorandum from Fund counsel and
independent counsel to the Independent Trustees regarding the responsibilities
of Trustees in connection with their consideration of whether to approve the
Trust's Investment Advisory Agreements. Finally, the Independent Trustees
receive advice from independent counsel to the Independent Trustees, meet in
executive session outside the presence of Fund management and participate in
question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, the Board requested and received written materials from SIMC and
the Sub-Advisers regarding: (a) the quality of SIMC's and the Sub-Advisers'
investment management and other services; (b) SIMC's and the Sub-Advisers'
investment management personnel; (c) SIMC's and the Sub-Advisers' operations and
financial condition; (d) SIMC's and the Sub-Advisers' brokerage practices
(including any soft dollar arrangements) and investment strategies; (e) the
level of the advisory fees that SIMC and the Sub-Advisers charge the Funds
compared with the fees each charge to comparable mutual funds; (f) the Funds'
overall fees and operating expenses compared with similar mutual funds; (g) the
level of SIMC's and the Sub-Advisers' profitability from their Fund-related
operations; (h) SIMC's and the Sub-Advisers' compliance systems; (i) SIMC's and
the Sub-Advisers' policies on and compliance procedures for personal securities
transactions; (j) SIMC's and the Sub-Advisers' reputation, expertise and
resources in domestic and/or international financial markets; and (k) the Funds'
performance compared with similar mutual funds.

At the March 13-13, 2008 meetings of the Board of Trustees, the Trustees,
including a majority of the Independent Trustees, approved the Investment
Advisory Agreements and approved the selection of SIMC and the Sub-Advisers to
act in their respective capacities for the Funds. The Board's approval was based
on its consideration and evaluation of a variety of specific factors discussed
at the meetings and at prior meetings, including:

- -    the nature, extent and quality of the services provided to the Funds under
     the Investment Advisory Agreements, including the resources of SIMC and the
     Sub-Advisers and their affiliates dedicated to the Funds;

- -    the Funds' investment performance and how it compared to that of other
     comparable mutual funds;

- -    the Funds' expenses under each Investment Advisory Agreement and how those
     expenses compared to those of other comparable mutual funds;

                                       47


Board of Trustees Considerations in Approving the Continuation of the Funds'
Advisory and Sub-Advisory Agreements (Unaudited) (concluded)

- -    the profitability of SIMC and the Sub-Advisers and their affiliates with
     respect to the Funds, including both direct and indirect benefits accruing
     to SIMC and the Sub-Advisers and their affiliates; and

- -    the extent to which economies of scale would be realized as the Funds grow
     and whether fee levels in the Investment Advisory Agreements reflect those
     economies of scale for the benefit of Fund investors.

NATURE, EXTENT AND QUALITY OF SERVICES. The Board of Trustees considered the
nature, extent and quality of the services provided by SIMC and the Sub-Advisers
to the Funds and the resources of SIMC and the Sub-Advisers and their affiliates
dedicated to the Funds. In this regard, the Trustees evaluated, among other
things, SIMC's and the Sub-Advisers' personnel, experience, track record and
compliance program. The Trustees found the level of SIMC's professional staff
and culture of compliance satisfactory. Following evaluation, the Board
concluded that, within the context of its full deliberations, the nature, extent
and quality of services provided by SIMC and the Sub-Advisers to the Funds and
the resources of SIMC and the Sub-Advisers and their affiliates dedicated to the
Funds supported renewal of the Investment Advisory Agreements.

FUND PERFORMANCE. The Board of Trustees considered Fund performance in
determining whether to renew the Investment Advisory Agreements. Specifically,
the Trustees considered the Funds' performance relative to their peer groups and
appropriate indices/benchmarks, in light of total return, yield and market
trends. As part of this review, the Trustees considered the composition of each
peer group and selection criteria. In evaluating performance, the Trustees
considered both market risk and shareholder risk expectations for the Funds. The
Trustees found Fund performance satisfactory, and where performance was below
the benchmark, the Trustees were satisfied that appropriate steps were being
taken. Following evaluation, the Board concluded that, within the context of its
full deliberations, the performance of the Funds supported renewal of the
Investment Advisory Agreements.

FUND EXPENSES. With respect to the Funds' expenses under the Investment Advisory
Agreements, the Trustees considered the rate of compensation called for by the
Investment Advisory Agreements and the Funds' net operating expense ratio in
comparison to those of other comparable mutual funds. The Trustees also
considered information about average expense ratios of comparable mutual funds
in the Funds' respective peer groups. The Trustees further considered the fact
that the comparative fee analysis either showed that the various fees were below
average or that there was a reasonable basis for the fee level. Finally, the
Trustees considered the effects of SIMC's voluntary waiver of management and
other fees and the Sub-Advisers' fees to prevent total Fund expenses from
exceeding a specified cap and that SIMC and the Sub-Advisers, through waivers,
have maintained the Funds' net operating expenses at competitive levels for
their respective distribution channels. Following evaluation, the Board
concluded that, within the context of its full deliberations, the expenses of
the Funds are reasonable and supported renewal of the Investment Advisory
Agreements.

PROFITABILITY. With regard to profitability, the Trustees considered all
compensation flowing to SIMC and the Sub-Adviser and their affiliates, directly
or indirectly. The Trustees considered whether the varied levels of compensation
and profitability under the Investment Advisory Agreements and other service
agreements were reasonable and justified in light of the quality of all services
rendered to the Funds by SIMC and the Sub-Advisers and their affiliates. The
Trustees found that profitability was reasonable and that the margin was not
increasing despite growth in assets. When considering the profitability of the
Sub-Advisers, the Board took into account the fact that the Sub-Advisers are
compensated by SIMC, and not by the Funds directly, and such compensation with
respect to any Sub-Adviser reflects an arms-length negotiation between the
Sub-Adviser and SIMC. Based on this evaluation, the Board concluded that, within
the context of its full deliberations, the profitability of SIMC and the
Sub-Advisers are reasonable and supported renewal of the Investment Advisory
Agreements.

ECONOMIES OF SCALE. The Trustees considered the existence of any economies of
scale and whether those were passed along to the Funds' shareholders through a
graduated investment advisory fee schedule or other means, including any fee
waivers by SIMC and its affiliates. Based on this evaluation, the Board
concluded that, within the context of its full deliberations, the Funds obtain
reasonable benefit from economies of scale.

Based on the Trustees' deliberation and their evaluation of the information
described above, the Board, including all of the Independent Trustees,
unanimously approved the continuation of the Investment Advisory Agreements and
concluded that the compensation under the Investment Advisory Agreements is fair
and reasonable in light of such services and expenses and such other matters as
the Trustees considered to be relevant in the exercise of their reasonable
judgment. In the course of their deliberations, the Trustees did not identify
any particular information that was all-important or controlling.
