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 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 (i) without charge, upon request, by calling 1-800-DIAL-SEI; and (ii) on the Commission’s website at http://www.sec.gov.

Per share calculations were performed using average shares.

For the six-month period ended July 31, 2012. All ratios for the period have been annualized.

†

Returns are for the period indicated and have not been annualized. Returns shown do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

††

The total return includes payment by affiliate. Had the payment been excluded the total return would have been 1.61%, 1.31%, 1.11% and 0.86% for Class A, Class B, Class C and Sweep Class, respectively. See Note 3 in Notes to Financial Statements.

(1)

Amount represents less than $0.01 per share.

(2)

The expense ratio includes the Treasury Guarantee Program expense. The Fund participated in the Temporary Guarantee Program for Money Market Funds from September 18, 2008 through September 18, 2009. Had the expense been excluded, the expense ratio would have been equal to, or less than, the expense ratio cap figure. See Note 3 for expense ratio cap figure.

(3)

The Distributor and/or Administrator have voluntarily agreed to waive and reduce its fee and/or reimburse certain expenses of the Fund in order to limit the one-day net income yield of the Fund to not less than 0.01% of the Fund’s average daily net assets of the share class. Had these waivers and the Treasury Guarantee Program expense been excluded the ratio would have been at the expense ratio cap figure. See Note 3 for expense ratio cap figure.

(4)

Amount represents less than 0.01%.

Amounts designated as “—” are $0 or have been rounded to $0.

SEI Daily Income Trust / Semi-Annual Report / July 31, 2012			45

Notes to Financial Statements (Unaudited)

July 31, 2012

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 and Treasury II (each a “Fund,” collectively the “Money Market Funds”), the Ultra Short Duration, Short-Duration Government, Intermediate-Duration Government and GNMA Bond (each a “Fund,” collectively the “Fixed Income Funds”). The Money Market Funds, 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 Duration Bond Fund seeks to provide higher current income than 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 (“GAAP”), requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from 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 Trust’s Board of Trustees. The Trust’s 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.

In accordance with U.S. GAAP, fair value is defined as the price that a 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. A three tier hierarchy has been established to maximize the use of observable and minimize the use of unobservable inputs and to establish classification of 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 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 based on the best information available in the circumstances.

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

Level 1 — Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Fund has the ability to access at the measurement date;

Level 2 — Quoted prices which are not active, or inputs that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and

Level 3 — Prices, inputs or exotic modeling techniques which are both significant to the fair value measurement and unobservable (supported by little or no market activity).

Investments are classified within the level of the lowest significant input considered in determining fair value. Investments classified


46		SEI Daily Income Trust / Semi-Annual Report / July 31, 2012

within Level 3 whose fair value measurement considers several inputs may include Level 1 or Level 2 inputs as components of the overall fair value measurement.

For the six-month period ended July 31, 2012, there have been no significant changes to the Trust’s fair valuation methodologies.

Security Transactions and Investment Income — Security transactions are recorded on the trade date. Costs used in determining net realized capital gains and losses on the sale of securities are on the basis of specific identification. Dividend income is recognized on the ex-dividend date, and interest income is recognized using the accrual basis of accounting. Income from payment-in-kind securities is recorded daily based on the effective interest method of accrual.

Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Trust estimates the components of distributions received that may be considered nontaxable distributions or capital gain distributions.

For the Fixed Income Funds, amortization and accretion is calculated using the scientific interest method, which approximates the effective interest method over the holding period of the security. Amortization of premiums and discounts is included in interest income.

For the Money Market Funds, all amortization is calculated using the straight line method over the holding period of the security. Amortization of premiums and accretion of discounts are included in interest income.

Repurchase Agreements — To the extent consistent with its Investment Objective and Strategies, securities pledged as collateral for repurchase agreements are held by each Fund’s custodian bank until the repurchase date of the repurchase agreement. 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 the repurchase date of the repurchase agreement. Provisions of the repurchase agreements and the Trust’s policies require that the market value of the collateral, including accrued interest thereon, is sufficient in the event of default by the counterparty. 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 Funds may be delayed or limited.

Futures Contracts — To the extent consistent with its Investment Objective and Strategies, the Fixed Income Funds’ utilized futures contracts during the six-month period ended July 31, 2012. These Funds’ investments in futures contracts are designed to enable the Funds to more closely approximate the performance of their benchmark indices. The Funds may use futures contracts for tactical hedging purposes as well as to enhance the Funds’ returns. 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 gains or losses 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 of entering into futures contracts include the possibility that there will be an imperfect price correlation between the futures and the underlying securities. Second, it is possible that a lack of liquidity for futures contracts could exist in the secondary market, resulting in an inability to close a position prior to its maturity date. Third, the futures contract involves the risk that the Fund could lose more than the original margin deposit required to initiate a futures transaction.

Finally, the risk exists that losses could exceed amounts disclosed on the Statements of Assets and Liabilities.

Swap Agreements — To the extent consistent with its Investment Objective and Strategies, a Fund’s investments in swap contracts is mainly used as an efficient means to take and manage risk in the portfolio, including interest rate risk, credit risk and overall yield sensitivity. 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. 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. Credit-default swaps involve periodic payments by a Fund or counterparty 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 recovery rate used to settle the contracts. The recovery rate is a function of how many credit default swap investors wish to deliver the security or receive the security. The recovery rate is determined through an auction process. 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 swap. 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 or some other form of indices 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


SEI Daily Income Trust / Semi-Annual Report / July 31, 2012			47

Notes to Financial Statements (Unaudited) (Continued)

July 31, 2012

of principal to manage a Fund’s exposure to interest rates. Payments received or made are recorded as realized gains or loss. A 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. Interest rate swap contracts outstanding at period end, if any, are listed after a Fund’s portfolio. In connection with swap agreements securities may be set aside as collateral by a 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, to protect a Fund’s value from changes in interest rates, or to 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 an unrealized gain or loss 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 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.

This risk is mitigated by having a master netting arrangement between a Fund and the counterparty and by having the counterparty post collateral to cover a Fund’s exposure to the counterparty. There were no outstanding swap agreements as of July 31, 2012.

Options Written/Purchased — To the extent consistent with its Investment Objective and Strategies, a Fund may invest in financial options contracts to add return or to hedge their existing portfolio securities. When the Fund writes or purchases an option, an amount equal to the premium received or paid by the Fund is recorded as a liability or an asset and is subsequently adjusted to the current market value of the option written or purchased. Premiums received or paid from purchasing or writing options which expire unexercised are treated by the Fund on the expiration date as realized gains or losses. The difference between the premium and the amount paid or received on effecting a closing purchase or sale transaction, including brokerage commissions, is also treated as a realized gain or loss. If an option is exercised, the premium paid or received is added to the cost of the purchase or proceeds from the sale in determining whether the Fund has realized a gain or a loss. The risk in writing a call option is that the Fund gives up the opportunity for profit if the market price of the security increases. The risk in writing a put option is that the Fund may incur a loss if the market price of the security decreases and the option is exercised. The risk in purchasing an option is that the Fund pays a premium whether or not the option is exercised. The Fund also

has the additional risk of being unable to enter into a closing transaction at an acceptable price if a liquid secondary market does not exist. Option contracts also involve the risk that they may not work as intended due to unanticipated developments in market conditions or other causes. Finally, the risk exists that losses could exceed amounts disclosed on the Statement of Assets and Liabilities.

TBA Purchase Commitments — To the extent consistent with its Investment Objective and Strategies, a Fixed Income Fund 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 — To the extent consistent with its Investment Objective and Strategies, a Fund 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 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 its 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 its Class and its collateral securities. 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


48		SEI Daily Income Trust / Semi-Annual Report / July 31, 2012

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 a Fund. 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 — Throughout the year, the Funds owned private placement investments that were purchased through private offerings or acquired through initial public offerings that could not be sold without prior registration under the Securities Act of 1933 or pursuant to an exemption there from. In addition, the Funds had 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 those investments. These investments were valued at amortized cost as determined in accordance with the valuation procedures approved by the Board of Trustees. At July 31, 2012, the Funds did not own any restricted securities.

Classes — Class-specific expenses are borne by that class of shares. Income, expenses, and realized and unrealized gains/losses and nonclass 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 Funds are prorated to the Funds on the basis of relative net assets.

Dividends and Distributions to Shareholders — Dividends from net investment income are declared daily and paid monthly. Any net realized capital gains on sales of securities after capital loss carryover are distributed at least annually by the Funds.

Redemption Fees — The Fixed Income Funds retain a redemption fee based on a dollar threshold for redemptions, or a series of redemptions, of capital shares held for less than thirty days, as presented below:


	Dollar Threshold ($ Thousands)		Redemption Fee
Ultra Short Duration Bond Fund	$	10,000		0.50	%
Short-Duration Government Fund		25,000		0.25	%
Intermediate-Duration Government Fund		10,000		0.25	%
GNMA Fund		10,000		0.25	%

For the six-month period ended July 31, 2012, the Fixed Income Funds did not retain any redemption fees. Such fees, if any, are retained by the Fixed Income Funds for the benefit of the remaining shareholders.

3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

Administration and Transfer Agency Agreement — SEI Investments Global Funds Services (the “Administrator”) provides administrative and transfer agency services to the Funds for annual fees, based on the average daily net assets of the respective funds, as presented below:

broker-dealer, acts as the Distributor of the shares of the Trust under a Distribution Agreement. The Trust also has adopted plans under which firms, including the Distributor, that provide shareholder and administrative services may receive compensation thereof. Specific classes of certain funds have also adopted distribution plans, pursuant to Rule 12b-1 under the Investment Company Act of 1940.

Such plans provide fees payable to the Distributor up to the following amounts, calculated as a percentage of the average daily net assets attributable to each particular class of each respective fund.

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 agreed to voluntarily waive 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 Statements of Operations. The Administrator and/or the Distributor

have voluntarily agreed to waive and reduce their fee and/or reimburse certain expenses of the Money Market Funds in order to limit the one-day net income yield of the Funds to not less than 0.01% of the Funds’ average daily net assets. The following table shows the waivers by class for the six-month period ended July 31, 2012 ($ Thousands):

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

A portion of 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 Adviser, Sub-Advisers and service providers as required by SEC regulations. The CCO’s services have been approved by and are reviewed annually by the Board of Trustees.

Interfund Lending — The SEC has granted an exemption that permits the Trust to participate in an interfund lending program (“The Program”) with existing or future investment companies registered under the 1940 Act that are advised by SIMC (the “SEI Funds”). The Program allows the SEI Funds to lend money to and borrow money from each other for temporary or emergency purposes. Participation in The Program is voluntary for both borrowing and lending funds. Interfund loans may be made only when the rate of interest to be charged is more favorable to the lending fund than an investment in overnight repurchase agreements (“Repo Rate”), and more favorable


50		SEI Daily Income Trust / Semi-Annual Report / July 31, 2012

to the borrowing fund than the rate of interest that would be charged by a bank for short-term borrowings (“Bank Loan Rate”). The Bank Loan Rate will be determined using a formula reviewed and approved annually by the SEI Funds Board of Trustees. The interest rate imposed on interfund loans is the average of the Repo Rate and the Bank Loan Rate. For the six-month period ended July 31, 2012, the Trust has not participated in The Program.

4. INVESTMENT ADVISORY AGREEMENTS

The Adviser serves as each Fund’s investment adviser and “manager of managers” under an investment advisory agreement approved by the shareholders of each Fund. Effective January 1, 2010, for its services, the Adviser receives an annual fee equal to 0.07% of each of the Money Market Funds’ net assets. Prior to January 1, 2010, for its services, the Adviser received 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 was calculated based on the combined assets of the Money Market Funds. The Adviser also received 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 Duration Bond Fund. The fee was calculated based on the net assets of the Ultra Short Duration Bond Fund. The Adviser also received 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 was calculated based on the combined assets of these Funds.

Pursuant to the “manager of managers” structure, the Board of Trustees approved BofA Advisors, LLC (formerly Columbia Management Advisors, LLC) as sub-adviser to the Money Market Funds, Logan Circle Partners, L.P. serves as a sub-adviser to the Ultra Short Duration Bond Fund and Wellington Management Company, LLP (“Wellington

LLP”) serves as sub-adviser to the Fixed Income Funds. For its services to the Funds, the sub-advisers are entitled to receive a fee paid directly by the Adviser.

5. INVESTMENT TRANSACTIONS

The cost of security purchases and the proceeds from the sale of securities, other than short-term investments, for the six-months ended July 31, 2012, were as follows for the Fixed Income Funds:


	Ultra Short Duration Bond Fund ($Thousands)		Short- Duration Government Fund ($Thousands)		Intermediate- Duration Government Fund ($Thousands)		GMNA Fund ($Thousands)

Other		66,959		997		110		72

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:


		Ordinary Income ($ Thousands)		Long-term Capital Gain ($ Thousands)		Total ($ Thousands)
Money Market Fund	2012	$	147	$	—	$	147

At January 31, 2012, the following Funds had capital loss carryforwards to offset future realized capital gains:


	Amount ($ Thousands)		Expiration
Government Fund	$	49		1/31/13
		4		1/31/14
		32		1/31/16
Prime Obligation Fund		67		1/31/17
Treasury Fund		1		1/31/13
		22		1/31/14
		5		1/31/15
Ultra Short Duration Bond Fund		1,020		1/31/13

		181		1/31/17
		3,642		1/31/18
		11,895		1/31/19

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 fiscal year ended January 31, 2012, the Government Fund, Government II Fund, Prime Obligation Fund, Treasury Fund and Treasury II Fund utilized, $3,738, $7,454, $35,648, $19,583 and $891, respectively, of capital loss carryforwards to offset capital gains.

Under the recently enacted Regulated Investment Company Modernization Act of 2010, Funds will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to

expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or longterm capital losses rather than being considered all short-term as under previous law.

Losses carried forward under these new provisions are as follows:


	Short-Term Loss		Long-Term Loss		Total*
Ultra Short Duration Bond Fund	$	—	$	4,092	$	4,092
Intermediate-Duration Government Fund		1,153		405		1,558

This table should be used in conjunction with the capital loss carryforwards table.

During the fiscal year ended January 31, 2012, the Money Market Funds’ cost of securities for Federal income tax purposes approximates the cost located in the Statements of Assets and Liabilities.

For Federal income tax purposes, the cost of securities owned at January 31, 2012, and net realized gains or losses on securities sold for the period, were different from amounts reported for financial reporting purposes, primarily due to wash sales which cannot be used for Federal income tax purposes in the current year and have been deferred for use in future years. The Federal tax cost and aggregate gross unrealized appreciation and depreciation on investments held by the Fixed Income Funds at July 31, 2012, were as follows:


	Federal Tax Cost ($ Thousands)		Appreciated Securities ($ Thousands)		Depreciated Securities ($ Thousands)			Net Unrealized Appreciation/ (Depreciation) ($ Thousands)
Ultra Short Duration Bond Fund	$	232,378	$	1,227	$	(2,656	)	$	(1,429	)
Short-Duration Government Fund		836,068		14,588		(83	)		14,505
Intermediate-Duration Government Fund		75,953		1,619		(48	)		1,571
GNMA Fund		370,314		10,939		(788	)		10,151


52		SEI Daily Income Trust / Semi-Annual Report / July 31, 2012

Management has analyzed the Funds’ tax positions taken on the federal tax returns for all open tax years and has concluded that as of January 31, 2012, no provision for income tax is required in the Funds’ financial statements. All uncertain tax positions, except for the accretion of market discount associated with the structured investment vehicles subject to the capital support agreement, meet the more likely than not criteria established in ASC paragraph 740. SEI Investment Company (“SEI”), which is the parent company of the Adviser, has agreed to indemnify the fund if the Internal Revenue Service (“IRS”) were to disagree with a position taken on the tax return for the fiscal year ended January 31, 2010. Accordingly, no provision for taxes is required. The Funds’ federal income and excise tax returns are subject to examination by the IRS for all open tax years under the applicable Statute of Limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

7. INVESTMENT RISKS

In the normal course of business, a Fund may enter into contracts that provide general indemnifications by a Fund to the counterparty to the contract. A Fund’s maximum exposure under these arrangements

is dependent on future claims that may be made against a Fund and, therefore, cannot be established; however, based on experience, management believes 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. SUBSEQUENT EVENTS

The Trust, on behalf of the Funds, has evaluated the need for disclosures and/or adjustments resulting from subsequent events. Based on this evaluation, no adjustments were required to the financial statements.

Disclosure of Fund Expenses (Unaudited)

All mutual funds have operating expenses. As a shareholder of a mutual 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 mutual fund’s gross income and directly reduce your final investment return. These expenses are expressed as a percentage of the mutual fund’s average net assets; this percentage is known as the mutual 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 after fee waivers 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 your Fund, to estimate the expenses you paid 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 your 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 mutual 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.

Board of Trustees Considerations in Approving

the 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 (each, a “Sub-Adviser” and collectively, 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 are also 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 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(s). In connection with their consideration of such approval(s), 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 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 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 from third parties. This information is provided 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 sessions outside the presence of Fund management and participate in question and answer sessions with representatives of SIMC and the Sub-Advisers.

Specifically, during the course of the Trust’s fiscal year, the Board requested and received written materials from SIMC and the Sub-Advisers regarding: (i) the quality of SIMC’s and the Sub-Advisers�� investment management and other services; (ii) SIMC’s and the Sub-Advisers’ investment management personnel; (iii) SIMC’s and the Sub-Advisers’ operations and financial condition; (iv) SIMC’s and the Sub-Advisers’ brokerage practices (including any soft dollar arrangements) and investment strategies; (v) 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; (vi) the Funds’ overall fees and operating expenses compared with similar mutual funds; (vii) the level of SIMC’s and the Sub-Advisers’ profitability from their Fund-related operations; (viii) SIMC’s and the Sub-Advisers’ compliance systems; (ix) SIMC’s and the Sub-Advisers’ policies on and compliance procedures for personal securities transactions; (x) SIMC’s and the Sub-Advisers’ reputation, expertise and resources in domestic and/or international financial markets; and (xi) the Funds’ performance compared with similar mutual funds.


56		SEI Daily Income Trust / Semi-Annual Report / July 31, 2012

At the March 27 – 28, 2012 meeting 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 meeting 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;

•

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 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 each Sub-Adviser’s personnel, experience, track record and compliance program. The Trustees found the level of SIMC’s and each Sub-Adviser’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 concluded 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.


SEI Daily Income Trust / Semi-Annual Report / July 31, 2012			57

Board of Trustees Considerations in Approving

the Advisory and Sub-Advisory Agreements (Unaudited) (Concluded)

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. 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 each 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 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.
