1. ORGANIZATION

SEI Institutional Investments Trust (the “Trust”) was organized as a Massachusetts business trust under a Declaration of Trust dated March 1, 1995. The Trust commenced operations on June 14, 1996.

The Trust is registered under the Investment Company Act of 1940, as amended, as an open-end investment company currently offering 16 Funds: Large Cap, Large Cap Diversified Alpha, Large Cap Disciplined Equity, Large Cap Index, Small Cap, Small/Mid Cap Equity, U.S. Managed Volatility, International Equity, World Equity Ex-US, Screened World Equity Ex-US, Enhanced LIBOR Opportunities, Core Fixed Income, High Yield Bond, Long Duration, Emerging Markets Debt and Real Return Funds (each a “Fund,” collectively, the “Funds”) each of which are diversified Funds with the exception of the Emerging Markets Debt Fund. The Trust is registered to offer Class A shares of all Funds. The assets of each Fund are segregated, and a shareholder’s interest is limited to the Fund in which shares are held. The Trust’s prospectus provides a description of each Fund’s investment objectives, policies, and strategies.

On May 13, 2009, the Board of Trustees approved the name and strategy change of the Real Return Plus Fund to the Real Return Fund.

2. SIGNIFICANT ACCOUNTING POLICIES

Financial Accounting Standards Board (“FASB”) has issued FASB ASC105 (formerly FASB Statement No. 168), The “FASB Accounting Standards Codification” and the Hierarchy of Generally Accepted Accounting Principles (“ASC 105”). ASC 105 established the FASB Accounting Standards Codification (“Codification” or “ASC”) as the single source of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal securities laws were also sources of authoritative GAAP for SEC registrants. The Codification superseded all existing non-SEC accounting and reporting standards. All other non-grandfathered, non-SEC accounting literature not included in the Codification have become non-authoritative.

Following the Codification, the FASB will not issue new standards in the form of Statements, FASB Staff Positions or Emerging Issues Task Force Abstracts. Instead, it will issue Accounting Standards Updates, which will serve to update the Codification, provide background information about the guidance and provide the basis for conclusions on the changes to the Codification.

GAAP was not intended to be changed as a result of the FASB’s Codification project, but it has changed the way the guidance is organized and presented. As a result, these changes have had an impact on how companies reference GAAP in their financial statements and in their accounting policies for financial statements issued for interim and annual periods ending after September 15, 2009. The Trust implemented the Codification as of November 30, 2009.

 

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 U.S. generally accepted accounting principles, requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets 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 — 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. Debt securities are priced based upon valuations provided by independent, third-party pricing agents, if available. 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 acquired with remaining maturities of sixty days or less may be valued at their amortized cost, which approximates market value. The prices for foreign securities are reported in local currency and converted to U.S. dollars using currency exchange rates. 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 Trust’s 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 a 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 a 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 a Fund calculates net asset value, the adviser or sub-adviser may request that a Fair Value Committee Meeting be called. In addition, the Trust’s 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 a 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.

The International Equity, World Equity Ex-US and Screened World Equity Ex-US Funds that hold international securities also use a third-party fair valuation vendor. The vendor provides a fair value for foreign securities held by these funds based on certain factors and methodologies (involving, generally, tracking valuation correlations between the U.S. market and each non-U.S. security). Values from the fair value vendor are applied in the event that there is a movement in the U.S. market that exceeds a specific threshold that has been established by the Committee. The Committee has also established a “confidence interval” which is used to determine the level of historical correlation between the value of a specific foreign security and movements in the U.S. market before a particular security will be fair valued when the threshold is exceeded. In the event that the threshold established by the Committee is exceeded on a specific day, these funds that hold international securities will value the non-U.S. securities within that fund that exceed the applicable “confidence interval” based upon the adjusted prices provided by the fair valuation vendor.

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.

In accordance with U.S. generally accepted accounting principles, 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 — quoted prices in active markets for identical investments
Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risks, etc.)
Level 3 — significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The valuation techniques used by the Funds to measure fair value during the six month period ended November 30, 2009 maximized the use of observable inputs and minimized the use of unobservable inputs.

For the six month period ended November 30, 2009, 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. Cost used in determining net realized capital gains and losses on the sale of securities is determined on the basis of specific identification. Dividend income and expense is recognized on the ex-dividend date, and interest income or expense 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 — A Fund may agree to purchase securities from financial institutions subject to the seller’s agreement to repurchase them at a mutually agreed upon date and price. It is the Fund’s policy that repurchase agreements are fully collateralized by U.S. Treasury and Government Agency securities. All collateral is held by the Fund’s custodian bank or a bank with which the custodian bank has entered into a subcustodian agreement, or is segregated in the Federal Reserve Book Entry System. In connection with transactions in

Table of Contents

 

repurchase agreements, if the seller defaults and the value of the collateral declines, or if the seller enters an insolvency proceeding, realization of the collateral by the Fund may be delayed or limited.

Reverse Repurchase Agreements — The Large Cap Diversified Alpha, Large Cap Disciplined Equity, International Equity, World Equity Ex-US, Screened World Equity Ex-US, Enhanced LIBOR Opportunities and Real Return Funds may issue reverse repurchase agreements. A reverse repurchase agreement involves the sale of portfolio assets together with an agreement to repurchase the same assets later at a fixed price. Additional assets are maintained in an account with the broker. The segregated assets may consist of cash, U.S. Government securities, or other liquid securities at least equal in value to the obligations under the reverse repurchase agreements. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, those Funds use of the proceeds under the reverse repurchase agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the obligation to repurchase the securities. There were no outstanding reverse repurchase agreements as of November 30, 2009.

Expenses — Expenses that are directly related to a Fund are charged directly to that Fund. Other operating expenses of the Funds are prorated to the Funds on the basis of relative 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 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 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 Funds may enter into forward foreign currency contracts as hedges against either specific transactions, fund positions or anticipated fund positions. All commitments are marked-to-market daily at the applicable foreign exchange rate, and any resulting unrealized gains or losses are recorded currently. The Large Cap Disciplined Equity, International Equity, World Equity Ex-US, Enhanced LIBOR Opportunities, Core Fixed Income and Emerging Markets Debt Funds realized gains and losses at the time forward contracts were 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. These 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 Schedule of Investments or the Statement of Assets and Liabilities.

Futures Contracts — Each of the Funds, with the exception of the High Yield Bond Fund, utilized futures contracts during the six month period ended November 30, 2009. 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 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 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 a 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 Schedule of Investments or the Statement of Assets and Liabilities.

Options/Swaptions Written/Purchased — A Fund may invest in financial options/swaptions contracts for the purpose of hedging its existing portfolio securities, or securities that a Fund intends to purchase, against fluctuations in fair market value caused by changes in prevailing market interest rates. The Core Fixed Income Fund may also invest in financial option/swaption contracts to enhance its returns. When the Fund writes or purchases an option/swaption, 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/swaption written or purchased. Premiums received or paid from writing or purchasing options/ swaptions 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/swaption 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 Core Fixed Income had options contracts and swaptions contracts as of November 30, 2009, as disclosed in the Fund’s Schedule of Investments.

The risk in writing a call option/swaption is a Fund may give up the opportunity for profit if the market price of the security increases. The risk in writing a put option/swaption is a Fund may incur a loss if the market price of the security decreases and the option/swaption is exercised. The risk in purchasing an option/swaption is a Fund may pay a premium whether or not the option/swaption 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/swaption 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 Schedule of Investments or the Statement of Assets and Liabilities.

Securities Sold Short — As consistent with each Fund’s investment objectives, a Fund may engage in short sales. Short sales are transactions under which a Fund sells a security it does not own. To complete such a transaction, a Fund must borrow the security to make delivery to the buyer. That Fund then is obligated to replace the security borrowed by purchasing the security at the market price at the time of the replacement. The price at such time may be more or less than the price at which the security was sold by a Fund. Until the security is replaced, a Fund is required to pay the lender amounts equal to any dividends or interest that accrue during the period of the loan. Dividends and interest are shown as an expense for financial reporting purposes. To borrow the security, a Fund also may be required to pay a premium, which would decrease proceeds of the security sold. The proceeds of the short sale are retained by the broker, to the extent necessary to meet margin requirements, until the short position is closed out. A gain, limited to the price at which a Fund sold the security short, or a loss, unlimited in size, will be recognized upon the close of a short sale.

Until a Fund closes its short position or replaces the borrowed security, that Fund will: (a) maintain a segregated account containing cash or liquid securities at such a level that (i) the amount deposited in the account plus the amount deposited with the broker as collateral will equal the current value of the security sold short; and (ii) the amount deposited in the segregated account plus the amount deposited with the broker as collateral will not be less than the market value of the security at the time the security was sold short, or (b) otherwise cover a Fund’s short positions. At November 30, 2009, none of the Funds held any short positions.

Swap Agreements — 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. Credit default swaps involve the periodic payment by a Fund or counterparty of interest based on a specified rate multiplied by a notional amount assigned to an underlying debt instrument or group of debt instruments in exchange for the assumption of credit risk on the same instruments. In the event of a credit event, usually in the form of a credit rating downgrade, the party receiving periodic payments (i.e. floating rate payer) must pay the other party (i.e. fixed rate payer) an amount equal to the outstanding principal of the downgraded debt instrument. Total return swaps allow an investor to benefit from the cash flow without ever actually owning the underlying security. The receiver must pay any decline in value to the payer at the end of the total return 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 (London Interbank Offered Rate) or some other form of index on the notional amount. Interest rate swaps involve the exchange by a Fund with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) with respect to a notional amount of principal to manage a Fund’s exposure to interest rates. Payments received or made are recorded as realized gains or losses. 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. In connection with swap agreements, securities/cash 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; protect a Fund’s value from changes in interest rates; or expose a Fund to a different security or market.

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

Entering into swap agreements involves, to varying degrees, elements of credit and market risk in excess of the amounts recognized on the 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. See Note 3 for further details.

Forward Treasury Commitments — A Fund may invest in commitments to purchase U.S. Treasury securities on an extended settlement basis. Such transactions involve the commitment to purchase a security with payment and delivery taking place in the future, sometimes a month or more after the transaction date. The Funds account for such transactions as purchases and sales and record an unrealized gain or loss each day equal to the difference between the cost of the purchase commitment and the current market value. Realized gains or losses are recorded upon closure or settlement of such commitments. No interest is earned prior to settlement of the transaction. These instruments are subject to market fluctuation due to changes in interest rates and the market value at the time of settlement could be higher or lower than the purchase price. A Fund may incur losses due to changes in the value of the underlying treasury securities from interest rate fluctuations or as a result of counterparty nonperformance.

Delayed Delivery Transactions — The Large Cap Disciplined Equity, Large Cap Diversified Alpha, Core Fixed Income, International Equity and World Equity Ex-US Funds may purchase or sell securities on a when-issued or delayed delivery basis. These transactions involve a commitment by those Funds to purchase or sell securities for a predetermined price or yield, with payment and delivery taking place beyond the customary settlement period. When purchasing a security on a delayed delivery basis, that 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. Those Funds may dispose of or renegotiate a delayed delivery transaction after it is entered into, and may sell when-issued securities before they are delivered, which may result in a capital gain or loss. When those Funds have sold a security on a delayed delivery basis, that Fund does not participate in future gains and losses with respect to the security.

Collateralized Debt Obligations — 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 security. 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 a Fund as illiquid securities; however, an active dealer market may exist for CDOs allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed income securities (e.g., interest rate risk and default risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) a Fund 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.

Dividends and Distributions to Shareholders — Dividends from net investment income are declared and paid to shareholders quarterly for the Large Cap, Large Cap Diversified Alpha, Large Cap Disciplined Equity, Large Cap Index, Small Cap, Small/Mid Cap Equity, U.S. Managed Volatility, Enhanced LIBOR Opportunities and Emerging Markets Debt Funds; declared daily and paid monthly for the Core Fixed Income, Long Duration and High Yield Bond Funds; and declared and paid at least annually for the International Equity, World Equity Ex-US, Screened World Equity Ex-US and Real Return Funds. Dividends and distributions are recorded on the ex-dividend date. Any net realized capital gains will be distributed at least annually by the Funds.

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.

Investments in Real Estate Investment Trusts (“REITs”) — 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. CREDIT DERIVATIVES

A Fund enters into credit default swaps to simulate long and short bond positions that are either unavailable or considered to be less attractively priced in the bond market. A Fund uses these swaps to reduce risk where a Fund has exposure to the issuer, or to take an active long or short position with respect to the likelihood of an event of default. The reference obligation of the swap can be a single issuer, a “basket” of issuers, or an index. The underlying referenced assets are corporate debt, sovereign debt and asset-backed securities.

The buyer of a credit default swap is generally obligated to pay the seller a periodic stream of payments over the term of the contract in return for a contingent payment upon the occurrence of a credit event with respect to an underlying reference obligation. Generally, a credit event for corporate or sovereign reference obligations means bankruptcy, failure to pay, obligation acceleration, repudiation/moratorium or restructuring. For credit default swaps on asset-backed securities, a credit event may be triggered by events such as failure to pay principal, maturity extension, rating downgrade or write-down.

 

If a Fund is a seller of protection, and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will generally either (i) pay to the buyer an amount equal to the notional amount of the swap and take delivery of the referenced obligation, other deliverable obligations, or underlying securities comprising a referenced index or (ii) pay a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising a referenced index.

If a Fund is a buyer of protection and a credit event occurs, as defined under the terms of that particular swap agreement, a Fund will either (i) receive from the seller of protection an amount equal to the notional amount of the swap and deliver the referenced obligation, other deliverable obligations or underlying securities comprising the referenced index or (ii) receive a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation or underlying securities comprising the referenced index. Recovery values are assumed by market makers considering either industry standard recovery rates or entity specific factors and considerations until a credit event occurs. If a credit event has occurred, the recovery value is determined by a facilitated auction whereby a minimum number of allowable broker bids, together with a specified valuation method, are used to calculate the settlement value.

Certain Funds are party to International Swap Dealers Association, Inc. Master Agreements (“ISDA Master Agreements”). These agreements are with select counterparties and they govern transactions, including certain over-the-counter derivative and foreign exchange contracts, entered into by the Funds and the counterparty.

As of November 30, 2009, the Core Fixed, Long Duration and the Emerging Markets Debt Funds are the buyers (“receiving protection”) on a total notional amount of $82.3 million, $0.0 million and $0.0 million, respectively) and are the sellers (“providing protection”) on a total notional amount of $79.5 million, $1.2 million and $0.9 million, respectively. The notional amounts of the swaps are not recorded in the financial statements; however the notional amount does approximate the maximum potential amount of future payments that the Funds could be required to make if the Funds were the sellers of protection and a credit event were to occur. Those credit default swaps (“CDS”) for which the Funds are providing protection at balance sheet date are summarized as follows:

*   The credit spread on the underlying asset is generally indicative of the current status of the underlying risk of the Fund having to perform. The spread also reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into a contract. Higher credit spreads with a shorter contract term is indicative of a higher likelihood of performance by the Fund.

The credit spread disclosed above for each reference obligation where the Fund is the seller of protection is a representation of the current payment/performance risk of the swap.

Other —The Distribution Agreement between SEI Investments Distribution Co. (the “Distributor”) and the Trust provides that the Distributor may receive compensation on fund transactions effected for the Trust in accordance with Securities and Exchange Commission (“SEC”) rules. Accordingly, it is expected that fund transactions may result in brokerage commissions being paid to the Distributor. The SEC rules require that such commissions not exceed usual and customary commissions.

Such commissions for the six-month period ended November 30, 2009 were as follows ($ Thousands):

 

Large Cap Fund    $ 16
Large Cap Diversified Alpha Fund      1
Small Cap Fund      375
Small/Mid Cap Equity Fund      341
International Equity Fund      14
World Equity Ex-US Fund      47

 

Certain officers and/or trustees of the Trust are also officers of the Distributor or the Adviser. The Trust pays each unaffiliated Trustee an annual fee for attendance at quarterly, interim and committee meetings. Compensation of officers and affiliated Trustees of the Trust is paid by the Adviser or Administrator.

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.

LSV Asset Management (partially-owned subsidiary of SIMC) serves as a sub-adviser to the Large Cap, Small Cap and Small/Mid Cap Equity Funds. For this service LSV Asset Management is entitled to receive a fee from SIMC. Such fees for the six-month period ended November 30, 2009 were as follows ($ Thousands):

 

Large Cap Fund    $ 74
Small Cap Fund      162
Small/Mid Cap Equity Fund      381

Fees Paid Indirectly — The Funds may direct certain fund trades to the Distributor who pays a portion of the Fund’s expenses. Accordingly, the expenses reduced, which were used to pay third party expenses, can be found on the Statement of Operations and the effect on the Fund’s expense ratio, as a percentage of the Fund’s average daily net assets for the six-month period ended November 30, 2009, can be found on the Financial Highlights.

Investment in Affiliated Security — The Funds may invest the cash collateral from the securities lending program in the SEI Liquidity Fund L.P.

8. 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 of America. These book/tax differences are either 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 period that the differences arise.

The tax character of dividends and distributions paid during the last two years or periods ended May 31, 2009 were as follows:

 

            Ordinary Income
($ Thousands)
   Long-Term Capital Gain
($ Thousands)
   Return of Capital

For Federal income tax purposes, the cost of securities owned at November 30, 2009, and the net realized gains or losses on securities sold for the period were not materially different from amounts reported for financial reporting purposes. These differences are primarily due to investments in partnerships and 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 aggregate gross unrealized appreciation and depreciation on total investments held by the Funds at November 30, 2009, was as follows:

Management has analyzed the Fund’s tax position taken on federal income tax returns for all open tax years and has concluded that as of November 30, 2009, no provision for income tax would be required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

 

9. CONCENTRATION/RISKS

In the normal course of business, the Trust enters into contracts that provide general indemnifications by the Trust to the counterparty to the contract. The Trust’s maximum exposure under these arrangements is dependent on future claims that may be made against the Trust and, therefore, cannot be estimated; however, management believes that, based on experience, the risk of loss from such claims is considered remote.

The market values of the Core Fixed Income, Long Duration and High Yield Bond Funds’ investments may 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.

The International Equity, World Equity Ex-US, Screened World Equity Ex-US and Emerging Markets Debt Funds concentrate their investments in securities of foreign issuers in various countries. These investments may involve certain considerations and risks not typically associated with investments in the United States, as a result of, among other factors, the possibility of future political and economic developments and the level of governmental supervision and regulation of securities markets in the respective countries.

11. 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 between 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 the SEI Liquidity Fund L.P., and the Fund bears all of the gains and losses on such investment. There is no guarantee that these investments will not lose value.

12. SUBSEQUENT EVENTS

Management has evaluated the need for disclosures and/or adjustments resulting from subsequent events through January 29, 2010, the date the financial statements were issued. Effective January 1, 2010, the Advisory Fee and Voluntary Expense Limitation for the Real Return Fund were reduced to 0.220% and 0.200%, respectively.

13. OTHER MATTERS

Due to volatility in the fixed income and equity markets, the market value of a Fund’s holdings may be materially different than shown in the Schedule of Investments (“SOI”). The values shown in the SOIs were the market values as of November 30, 2009 and do not reflect any market events after November 30, 2009.

Disclosure of Fund Expenses (Unaudited)

November 30, 2009

 

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

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

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

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

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

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

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

 

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

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

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

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

Board of Trustees Considerations in Approving the Advisory and Sub-Advisory Agreements (Unaudited) (Continued)

 

At the June 24-25, 2009 and September 17-18, 2009 meetings of the Board of Trustees, the Trustees, including a majority of the Independent Trustees, approved the Investment Advisory Agreements and approved the selection of SIMC and the Sub-Advisers to act in their respective capacities for the Funds. The Board’s approval was based on its consideration and evaluation of a variety of specific factors discussed at the meetings and at prior meetings, including:

 

 

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

 

 

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

 

 

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

 

 

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

 

 

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

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

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

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

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

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

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