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  web site 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.

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 Funds' prospectuses provide a
description of each Fund's investment objectives, policies and strategies. 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
accounting principles generally accepted in the United States of America,
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 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 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. As of July 31, 2006, there were no fair valued securities in the
Funds.

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.

SEI Daily Income Trust / Semi-Annual Report / July 31, 2006                   39



NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)




FUTURES CONTRACTS -- The Short-Duration Government Fund, the
Intermediate-Duration Government Fund and the GNMA Fund utilized futures
contracts during the six months ended July 31, 2006. 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 Statement of Net
Assets in the Short-Duration Government Fund, the Intermediate-Duration
Government Fund and the GNMA Fund represents the Fund's total exposure in such
contracts, whereas only the net unrealized appreciation (depreciation) is
reflected in the Fund's net assets.

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 LOAN OBLIGATIONS -- The Funds may invest in 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.

Normally, CLOs are privately offered and sold, and thus, are not registered
under the securities laws.

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, 2006, 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 Fund has 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 fair value as determined in accordance with the procedures approved by
the Board of Trustees. The acquisition dates of these investments, the
enforceable right to acquire these securities, along with their cost and values
at July 31, 2006, were as follows:

   expenses. These payments may be used to compensate sweep class shareholders
   who provide distribution-related services to their customers.

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. These
reclassifications, which have no impact on net asset value of the Fund, are
primarily attributable to expiration of capital loss carryforwards and tax
treatment of paydown gain (loss) on mortgage and asset-backed securities.

The Government Fund, Government II Fund, Treasury II Fund and GNMA Fund have
permanent book/tax differences due to the expiration of capital loss
carryforwards. The Government Fund, Government II Fund, Treasury II Fund and
GNMA Fund have $5,064, $38,015, $147,748 and $237,677 of capital losses,
respectively, which have expired as of January 31, 2006.

For Federal income tax purposes, capital loss carryforwards may be carried
forward and applied against future capital gains. Post-October losses represent
losses realized on investment transactions from November 1, 2005 through January
31, 2006 that, in accordance with Federal income tax regulations, the Funds may
elect to defer and treat as having arisen in the following fiscal year.

At July 31, 2006 the Money Market Funds cost of securities for Federal income
tax purposes approximates the cost located in the Statement of Net Assets.

The Federal tax cost and aggregate gross unrealized appreciation and
depreciation on investments held by the Fixed Income Funds at July 31, 2006,
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.

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.

9. NEW ACCOUNTING PRONOUNCEMENT

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
interpretation 48 ("FIN 48"), "ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES." This
standard defines the threshold for recognizing the benefits of tax-return
positions in the financial statements as "more-likely-than-not" to be sustained
by the taxing authority and requires measurement of a tax position meeting the
more-likely-than-not criterion, based on the largest benefit that is more than
50 percent likely to be realized. FIN 48 is effective as of the beginning of the
first fiscal year beginning after December 15, 2006. At adoption, companies must
adjust their financial statements to reflect only those tax positions that are
more-likely-than-not to be sustained as of the adoption date. As of July 31,
2006, the Funds have not evaluated the impact that will result from adopting FIN
48.

SEI DAILY INCOME TRUST -- JULY 31, 2006



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:

o 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."

o 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, 2006                   47



BOARD OF TRUSTEES CONSIDERATIONS IN APPROVING THE CONTINUATION OF THE FUNDS'
ADVISORY AND SUB-ADVISORY AGREEMENTS (Unaudited)


The 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 each series of the Trust (each, a
"Fund" and, collectively, 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 each Sub-Adviser's 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, each Fund's 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 Fund; 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 Fund's 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 each of
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
each Sub-Adviser 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 advisory fees that SIMC and each Sub-Adviser charges a Fund compared
with the fees each charges to comparable mutual funds; (f) a Fund's overall fees
and operating expenses compared with similar mutual funds; (g) the level of
SIMC's and each Sub-Adviser's profitability from its 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) each
Fund's performance compared with similar mutual funds.

At the March 8 and March 9, 2006 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:

o     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;




- --------------------------------------------------------------------------------
48                   SEI Daily Income Trust / Semi-Annual Report / July 31, 2006







o     each Fund's investment performance and how it compared to that of other
      comparable mutual funds;

o     each Fund's expenses under each Investment Advisory Agreement and how
      those expenses compared to those of other comparable mutual funds;

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

o     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. 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 each Fund's performance relative to its peer group and
appropriate indices/benchmarks, in light of total return, yield and market
trends. As part of this review, the Trustees considered the composition of the
peer group and selection criteria. In evaluating performance, the Trustees
considered both market risk and shareholder risk expectations for a given Fund.
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 each Fund's 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 each Fund's respective peer group. 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-Advisers 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. When
considering the profitability of the Sub-Advisors, the Board took into account
the fact that the Sub-Advisors are compensated by SIMC, and not by the Funds
directly, and such compensation with respect to any Sub-Advisor reflects an
arms-length negotiation between the Sub-Advisor 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 is 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 a Fund's 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.
