ORGANIZATION SEI Institutional Managed Trust (the "Trust") is organized as a Massachusetts Business Trust under a Declaration of Trust dated October 20, 1986. The Trust is registered under the Investment Company Act of 1940, as amended, as an open-end investment company with 15 Funds: Large Cap Diversified Alpha, Tax-Managed Large Cap, Large Cap Value, Large Cap Growth, Tax-Managed Small Cap, Small Cap Value, Small Cap Growth, Mid-Cap, U.S. Managed Volatility, Real Estate, Core Fixed Income, High Yield Bond, Enhanced Income, Global Managed Volatility and Small/Mid Cap Equity Funds (each a "Fund," collectively the "Funds"). The Trust is registered to offer Class A shares of the Funds, Class I shares of the Large Cap Diversified Alpha, Large Cap Value, Large Cap Growth, Small Cap Value, Small Cap Growth, Small/Mid Cap Equity, Mid-Cap and Core Fixed Income Funds, and Class Y shares of Tax-Managed Large Cap Fund. The assets of each Fund are segregated, and a shareholder's interest is limited to the Fund in which shares are held. The Funds' prospectuses provide a description of each Fund's investment objective, policies, and strategies. As of March 31, 2006, the Small/Mid Cap Equity, Enhanced Income and Global Managed Volatility Funds had not yet commenced operations. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of the significant accounting policies followed by the Funds. USE OF ESTIMATES -- The preparation of financial statements, in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities 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 of operations during the reporting period. Actual results could differ from those estimates. SECURITY VALUATION -- Securities listed on a securities exchange, market or automated quotation system for which quotations are readily available (except for securities traded on NASDAQ) are valued at the last quoted sale price on the primary exchange or market (foreign or domestic) on which they are traded, or, if there is no such reported sale, at the most recent quoted bid price. For securities traded on NASDAQ, the NASDAQ Official Closing Price will be used. 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. For securities that principally trade on a foreign market or exchange, a significant gap in time can exist between the time of a particular security's last trade and the time at which a Fund calculates its net asset value. The closing prices of such securities may no longer reflect their market value at the time the Fund calculates net asset value if an event that could materially affect the value of those securities (a "Significant Event") has occurred between the time of the security's last close and the time that the Fund calculates net asset value. A Significant Event may relate to a single issuer or to an entire market sector. If the adviser or sub-adviser of a Fund becomes aware of a Significant Event that has occurred with respect to a security or group of securities after the closing of the exchange or market on which the security or securities principally trade, but before the time at which the Fund calculates net asset value, it may request that a Fair Value Committee Meeting be called. In addition, the Funds' administrator monitors price movements among certain selected indices, securities and/or baskets of securities that may be an indicator that the closing prices received earlier from foreign exchanges or markets may not reflect market value at the time the Fund calculates net asset value. If price movements in a monitored index or security exceed levels established by the administrator, the administrator notifies the adviser or sub-adviser for any Fund holding the relevant securities that such limits have been exceeded. In such event, the adviser or sub-adviser makes the determination whether a Fair Value Committee Meeting should be called based on the information provided. Options and warrants for which the primary market is a national securities exchange are valued at the last sale price on the exchange on which they are traded, or, in the absence of any sale, at the closing bid price. Options and warrants not traded on a national securities exchange are valued at the last quoted bid price. 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 - -------------------------------------------------------------------------------- 138 SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 basis of specific identification. Dividend income is recognized on the ex-dividend date, and interest income is recognized using the accrual basis of accounting. 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. 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. REPURCHASE AGREEMENTS -- 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. Tri-Party Repurchase agreements purchased as collateral for securities on loan are maintained by the securities lending agent (see note 7). 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. COMPENSATING BALANCES -- Funds with cash overdrafts in excess of $100,000 are required to leave 112% in compensating balance with Wachovia Bank NA, the custodian of the Trust, on the following day. Funds with positive cash balances in excess of $100,000 are allowed to overdraw 90% of the balance with Wachovia Bank NA on the following day. 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 daily net assets. 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. FOREIGN CURRENCY TRANSLATION -- The books and records of the Funds investing in international securities are maintained in U.S. dollars on the following basis: (I) market value of investment securities, assets and liabilities at the current rate of exchange; and (II) purchases and sales of investment securities, income and expenses at the relevant rates of exchange prevailing on the respective dates of such transactions. The Funds investing in international securities do not isolate that portion of gains and losses on investments in equity securities that is due to changes in the foreign exchange rates from that which is due to changes in market prices of equity securities. The Funds investing in international securities report certain foreign-currency-related transactions as components of realized gains for financial reporting purposes, whereas such components are treated as ordinary income for Federal income tax purposes. FORWARD FOREIGN CURRENCY CONTRACTS -- The Small Cap Growth and Core Fixed Income Funds may enter into forward foreign currency contracts as hedges against either specific transactions, fund positions or anticipated fund positions. The Core Fixed Income Fund may also engage in currency transactions to enhance the Fund's returns. All commitments are "marked-to-market" daily at the applicable foreign exchange rate, and any resulting unrealized gains or losses are recorded currently. The Small Cap Growth and Core Fixed Income Funds realize gains and losses at the time forward contracts are extinguished. Unrealized gains or losses on outstanding positions in forward foreign currency contracts held at the close of the period are recognized as ordinary income or loss for Federal income tax purposes. The Funds could be exposed to risk if the counterparties to the contracts are unable to meet the terms of the contract and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. Finally, the risk exists that losses could exceed amounts disclosed on the Statement of Net Assets or Statement of Assets and Liabilities. At the period ended March 31, 2006 the Small Cap Growth Fund did not have any forward foreign currency contracts outstanding. FUTURES CONTRACTS -- All Funds, with the exception of Real Estate Fund, utilized futures contracts during the period ended March 31, 2006. The Funds' investments in futures contracts are designed to enable the Funds to more closely approximate the performance of their benchmark indices. The Core Fixed Income Fund may use futures contracts for tactical hedging purposes as well as to enhance the Fund's 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 Fund records 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 Statement of Net Assets or Statement of Assets and Liabilities. - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 139 NOTES TO FINANCIAL STATEMENTS (Unaudited)(Continued) March 31, 2006 OPTION WRITING/PURCHASING -- Each Fund may invest in financial option contracts for the purpose of hedging its existing fund securities, or securities that the Fund intends to purchase, against fluctuations in fair value caused by changes in prevailing market interest rates. The Core Fixed Income Fund may also invest in financial option contracts to enhance the Fund's returns. 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 writing or purchasing 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 on investment transactions. The Large Cap Diversified Alpha and Core Fixed Income Funds had option contracts as of March 31, 2006 as disclosed in the Funds' Statement of Net Assets or Schedule of Investments. The risk in writing a call option is that the Funds give up the opportunity for profit if the market price of the security increases. The risk in writing a put option is that the Funds 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 Funds pay a premium whether or not the option is exercised. The Funds also have 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 on written options could exceed amounts disclosed on the Statement of Net Assets or Statement of Assets and Liabilities. Written option transactions entered into during the six month period ended March 31, 2006 are summarized as follows: - ------------------------------------------------------------------------------ Large Cap Diversified Alpha Core Fixed Income - ------------------------------------------------------------------------------ # of Premium # of Premium Contracts ($Thousands) Contracts ($Thousands) - ------------------------------------------------------------------------------ Balance at the beginning of period -- $ -- 812 $ 332 Written 98 69 1,649 800 Expired -- -- (706) (276) Closing Buys -- -- (444) (182) - ------------------------------------------------------------------------------ Balance at the end of period 98 $ 69 1,311 $ 674 ============================================================================== At March 31, 2006 the Large Cap Diversified Alpha and Core Fixed Income Funds had cash and/or securities at least equal to the value of written options. 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. 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 the 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 outstanding principal of the downgraded debt instrument, and also take possession of the 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 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. 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, to protect the 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. DELAYED DELIVERY TRANSACTIONS -- The Core Fixed Income Fund may purchase or sell securities on a when-issued or delayed delivery basis. These transactions involve a commitment by the Fund to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When delayed delivery purchases are outstanding, the Fund will set aside liquid assets in an amount sufficient to meet the purchase price. When purchasing a security on a delayed delivery basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its net asset value. The Fund may dispose of or renegotiate a delayed delivery transaction after it is entered into, and - -------------------------------------------------------------------------------- 140 SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 may sell when-issued securities before they are delivered, which may result in a capital gain or loss. When the Fund has sold a security on a delayed delivery basis, the Fund does not participate in future gains and losses with respect to the security. 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 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 are 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 March 31, 2006, the following Fund 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 March 31, 2006, were as follows: NUMBER ACQUISITION RIGHT TO ACQUIRE COST MARKET VALUE % OF NET OF SHARES DATE DATE ($THOUSANDS) ($THOUSANDS) ASSETS - -------------------------------------------------------------------------------------------------------------- SMALL CAP GROWTH FUND Parkervision Warrants 17,500 06/20/05 06/20/05 $ 36 $ 86 0.0% Synenco Energy 37,852 08/19/05 08/19/05 530 632 0.1 Spatialight 100,000 01/12/06 01/12/06 262 319 0.0 ---- ------ ---- $828 $1,037 0.1% ==== ====== ==== DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment income are declared and paid to shareholders quarterly for the Large Cap Diversified Alpha, Tax-Managed Large Cap, Large Cap Value, Large Cap Growth, Tax-Managed Small Cap, Small Cap Value, Small Cap Growth, Mid-Cap, U.S. Managed Volatility and Real Estate Funds; and declared daily and paid monthly for the Core Fixed Income and High Yield Bond Funds. Any net realized capital gains on sales of securities are distributed to shareholders at least annually. Dividends and distributions are recorded on the ex-dividend date. INVESTMENTS IN REITS -- With respect to the Real Estate Fund, dividend income is recorded based on the income included in distributions received from the REIT investments using published REIT reclassifications including some management estimates when actual amounts are not available. Distributions received in excess of this estimated amount are recorded as a reduction of the cost of investments or reclassified to capital gains. The actual amounts of income, return of capital, and capital gains are only determined by each REIT after its fiscal year-end, and may differ from the estimated amounts. 3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES ADMINISTRATION AND TRANSFER AGENCY AGREEMENT -- The Trust and SEI Investments Global Funds Services (the "Administrator") are parties to an amended and restated Administration and Transfer Agency Agreement dated December 10, 2003 under which the Administrator provides administrative and transfer agency services to the Funds for an annual fee of 0.35% of the average daily net assets of the Large Cap Diversified Alpha, Tax-Managed Large Cap Class A, Large Cap Value, Large Cap Growth, Tax-Managed Small Cap, Small Cap Value, - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 141 NOTES TO FINANCIAL STATEMENTS (Unaudited)(Continued) March 31, 2006 Small Cap Growth, Mid-Cap, U.S. Managed Volatility, Real Estate and High Yield Bond Funds; 0.15% of average daily net assets of the Tax-Managed Large Cap Class Y; and 0.28% of the average daily net assets of the Core Fixed Income Fund.

INVESTMENT ADVISORY AGREEMENT -- SEI Investments Management Corporation ("SIMC") serves as investment adviser (the "Adviser") to each Fund. In connection with serving as Adviser, SIMC is entitled to a fee, which is calculated daily and paid monthly, based on the average daily net assets of each Fund. SIMC has voluntarily agreed to waive a portion of its fee so that the total annual expenses of each Fund, exclu- sive of short sale expenses, will not exceed certain voluntary expense limitations adopted by SIMC. These waivers may be terminated at any time.

DISTRIBUTION AGREEMENT -- SEI Investments Distribution Co. (the "Distributor"), a wholly-owned subsidiary of SEI Investments Company ("SEI Investments"), serves as each Fund's Distributor pursuant to a distribution agreement with the Trust. The Trust has adopted a shareholder servicing plan for Class A, Class I and Class Y shares (the "Shareholder Servicing Plans") under which a shareholder servicing fee of up to 0.25% of average daily net assets attributable to Class A and Class I shares, and a shareholder servicing fee of up to 0.15% of average daily net assets attributable to Class Y shares, will be paid to the Distributor. In addition to the Shareholder Servicing Plans, the Class I shares have adopted administrative service plans that provide for administrative service fees payable to the Distributor of up to 0.25% of the average daily net assets attributed to that class. OTHER -- The Distribution Agreement between the Distributor and the Trust provides that the Distributor may receive compensation on fund transactions effected for the Trust in accordance with the rules of the Securities and Exchange Commission ("SEC"). Accordingly, it is expected that fund transactions may result in brokerage commissions being paid to the Distributor.

FEDERAL TAX INFORMATION It is each Fund's intention to continue to qualify as a regulated investment company under Subchapter M of The Internal Revenue Code and distribute all of its taxable income (including net capital gains). Accordingly, no provision for Federal income taxes is required. Dividends from net investment income and distributions from net realized capital gains are determined in accordance with U.S. Federal income tax regulations, which may differ from those amounts determined under accounting principles generally accepted in the United States.

For Federal income tax purposes, the cost of securities owned at March 31, 2006, and the 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 Funds at March 31, 2006, were as follows: - -------------------------------------------------------------------------------- Net Unrealized Appreciated Depreciated Appreciation Securities Securities (Depreciation) ($ Thousands) ($ Thousands) ($ Thousands) - -------------------------------------------------------------------------------- Large Cap Diversified Alpha Fund $37,747 $(19,811) $17,936 Tax-Managed Large Cap Fund 503,098 (44,785) 458,313 Large Cap Value Fund 748,548 (77,438) 671,110 Large Cap Growth Fund 613,623 (94,415) 519,208 Tax-Managed Small Cap Fund 74,410 (4,562) 69,848 Small Cap Value Fund 264,537 (31,995) 232,542 Small Cap Growth Fund 233,514 (74,789) 158,725 Mid-Cap Fund 16,554 (1,656) 14,898 U.S. Managed Volatility Fund 18,876 (3,469) 15,407 Real Estate 32,644 (7) 32,637 Core Fixed Income Fund 34,267 (73,887) (39,620) High Yield Bond Fund 19,653 (15,955) 3,698 - -------------------------------------------------------------------------------- 146 SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 7. SECURITIES LENDING Each Fund may lend portfolio securities to brokers, dealers and other financial organizations that meet capital and other credit requirements or other criteria established by the Trust's Board of Trustees. These loans may not exceed 33 1/3% of the total asset value of the Fund (including the loan collateral). No Fund will lend portfolio securities to its Adviser, sub-adviser or their affiliates unless it has applied for and received specific authority to do so from the SEC. Loans of portfolio securities will be fully collateralized by cash. Collateral will be maintained in an amount equal to at least 100% of the current market value of the loaned securities by marking to market daily, although the borrower will be required to deliver collateral of 102% and 105% of the market value of borrowed securities for domestic and foreign securities, respectively. However, due to market fluctuations during the day, the value of securities loaned on a particular day may, during the course of the day, exceed the value of collateral. On each business day, the amount of collateral is adjusted based on the prior day's market fluctuations and the current day's lending activity. Income from lending activity is determined by the amount of interest earned on collateral, less any amounts payable to the borrowers of the securities and the lending agent. Lending securities involves certain risks, including the risk that the Fund may be delayed or prevented from recovering the collateral if the borrower fails to return the securities. Cash collateral received in connection with securities lending is invested in short-term investments by the lending agent. These investments may include repurchase agreements, which are collateralized by United States Treasury and Government Agency securities, and high-quality, short-term instruments, such as floating rate corporate obligations, commercial paper, and private placements with an average weighted maturity not to exceed 60 days and a maturity not to exceed 397 days. 8. CONCENTRATIONS/RISKS In the normal course of business, the Funds enter into contracts that provide general indemnifications by the Funds 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 estimated; however, based on experience, the risk of loss from such claims is considered remote. The market values of the Core Fixed Income and High Yield Bond Funds' investments will change in response to interest rate changes and other factors. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline. Changes by recognized rating agencies in the ratings of any fixed income security and in the ability of an issuer to make payments of interest and principal may also affect the value of these investments. 9. IN-KIND TRANSFERS OF SECURITIES During the year ended September 30, 2005, the Large Cap Value and U.S. Managed Volatility Funds issued (redeemed) shares of beneficial interest in exchange for securities. The securities were transferred at their current value on the date of transaction. - ------------------------------------------------------------------------------ Shares Issued (Redeemed) Value Gain - ------------------------------------------------------------------------------ Large Cap Value Fund 10/28/04 (301,626) $ 5,993,304 $ 306,542 U.S. Managed Volatility Fund 10/28/04 599,330 5,993,304 -- 10. LITIGATION The Core Fixed Income Fund has participated as a plaintiff bondholder, along with other institutional bondholders, in litigation against Duty Free International, British Airport Authority and other defendants relating to Notes issued by Duty Free International which are held by the Fund. British Airport Authority is the former parent company of Duty Free International. During 2003, the plaintiffs in that action reached a settlement with all defendants with the exception of British Airport Authority. Under that settlement, Duty Free International paid the plaintiffs $4,310,636 which is approximately 70% of the par value of the bonds. The settlement also contained provisions for the issuance of a $10 million Note by Duty Free International to the bondholders, subject to certain conditions. The Fund, along with other bondholders, subsequently agreed to sell the Note to Duty Free International. The final installment of the purchase price of the Note was received by the Fund in December 2005. The litigation proceeded to jury trial against British Airport Authority in December 2003, and the jury found against the plaintiffs on all counts. Plaintiffs subsequently appealed. In January 2006, the Court of Appeals ruled in favor of plantiffs and remanded for a new trial. The Core Fixed Income Fund is bearing its portion of the legal expenses associated with this litigation over and above the expense caps of the Fund. - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 147 NOTES TO FINANCIAL STATEMENTS (Unaudited)(Concluded) March 31, 2006 11.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board has selected KPMG LLP ("KPMG") to serve as the Trust's independent registered public accounting firm for the Trust's fiscal year ended September 30, 2006. The decision to select KPMG was recommended by the Audit Committee and was approved by the Board on September 21, 2005. During the Trust's fiscal years ended September 30, 2005 and September 30, 2004, neither the Trust, its portfolios nor anyone on their behalf has consulted with KPMG on items which (i) concerned the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Trust's financial statements; or (ii) concerned the subject of a disagreement (as defined in paragraph (a)(1)(iv) of Item 304 of Regulation S-K) or reportable events (as described in paragraph (a)(1)(iv) of said Item 304). The selection of KPMG does not reflect any disagreements with or dissatisfaction by the Trust or the Board with the performance of the Trust's prior auditor. The decision to dismiss PricewaterhouseCoopers LLP ("PwC"), the Trust's previous independent registered public accounting firm and to select KPMG was recommended by the Trust's Audit Committee and approved by the Fund's Board of Trustees. PwC's report on the Trust's financial statements for the fiscal years ended September 30, 2005 and September 30, 2004 contained no adverse opinion or disclaimer of opinion nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Trust's fiscal years ended September 30, 2005 and September 30, 2004, (i) there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused it to make reference to the subject matter of the disagreements in connection with its reports on the Trust's financial statements for such years, and (ii) there were no "reportable events" of the kind described in Item 302(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended. - -------------------------------------------------------------------------------- 148 SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 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: o 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." o 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. - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 149 DISCLOSURE OF FUND EXPENSES (Unaudited) (Concluded) -

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-Adviser's investment management and other services; (b) SIMC's and the Sub-Adviser's investment management personnel; (c) SIMC's and the Sub-Adviser's operations and financial condition; (d) SIMC's and the Sub-Adviser's brokerage practices (including any soft dollar arrangements) and investment strategies; (e) the level of the advisory fees that SIMC and each Sub-Adviser charge a Fund compared with the fees each charge 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-Adviser's compliance systems; (i) SIMC's and the Sub-Adviser's policies on and compliance procedures for personal securities transactions; (j) SIMC's and the Sub-Adviser's reputation, expertise and resources in domestic and/or international financial markets; and (k) each Fund's performance compared with similar mutual funds. - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 151 BOARD OF TRUSTEES CONSIDERATIONS IN APPROVING THE ADVISORY AND SUB-ADVISORY AGREEMENTS (Unaudited)(Concluded) At the April 27, 2005, June 23, 2005, September 20, 2005, September 21, 2005, December 7, 2005, December 8, 2005, March 8, 2006 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; 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. - -------------------------------------------------------------------------------- 152 SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 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-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 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. - -------------------------------------------------------------------------------- SEI Institutional Managed Trust / Semi-Annual Report / March 31, 2006 153 NOTES NOTES NOTES SEI INSTITUTIONAL MANAGED TRUST SEMI-ANNUAL REPORT MARCH 31, 2006 Robert A.
