State Street Target Retirement 2070 Fund

Investment Objective

The investment objective of the State Street Target Retirement 2070 Fund (the “Target Retirement 2070 Fund” or the “Fund”) is to seek capital growth and income over the long term.

Fees and Expenses of the Fund

The tables below describe the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries which are not reflected in the tables and examples below.

Shareholder Fees (fees paid directly from your investment)

	Class I	Class K	Class R3
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None	None	None
Maximum Deferred Sales Charge (Load) (as a percentage of the lower of the sale proceeds or the original offering price)	None	None	None

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

	Class I	Class K	Class R3
Management Fee	____%	____%	____%
Distribution and/or Shareholder Service (12b-1) Fees	____%	____%	____%
Other Expenses1	____%	____%	____%
Acquired Fund Fees and Expenses	____%	____%	____%
Total Annual Fund Operating Expenses	____%	____%	____%
Less Fee Waivers and/or Expense Reimbursements2	____%	____%	____%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	____%	____%	____%

Other Expenses are based on estimates for the current fiscal year.

The Fund's investment adviser, SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”), is contractually obligated until [ ] (i) to waive up to the full amount of the advisory fee payable by the Fund, and/or (ii) to reimburse the Fund to the extent that Total Annual Fund Operating Expenses (exclusive of non-recurring account fees, interest, taxes, extraordinary expenses, and distribution, shareholder servicing, and sub-transfer agency fees) exceed 0.09% of average daily net assets on an annual basis. This waiver and/or reimbursement may not be terminated prior to [ ] except with approval of the Fund's Board of Trustees.

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The calculation of costs for the one-year period takes into account the effect of any current contractual fee waivers and/or reimbursements; and the calculation of costs for the remaining periods takes such fee waivers and/or reimbursements into account only for the first year of each such period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 year	3 years
Class I	$[]	$[]
Class K	$[]	$[]
Class R3	$[]	$[]

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. The Fund had not commenced operations as of the date of this Prospectus and, as a result, does not yet have a portfolio turnover rate.

Principal Investment Strategies

SSGA Funds Management, Inc. (“SSGA FM” or the “Adviser”), the investment adviser to the Fund, manages the Target Retirement 2070 Fund using a proprietary asset allocation strategy. The Fund is a “fund of funds” that invests in a combination of mutual funds and ETFs sponsored by the Adviser or its affiliates (the “Underlying Funds”). The Underlying Funds may invest in a wide variety of asset classes, including equity and fixed-income securities of issuers anywhere in the world, including emerging markets investments, and including, among others, high yield, commodity, and real estate investments. The Underlying Funds may invest in obligations of domestic U.S. issuers, non-U.S. issuers, or both.

The Fund is intended for investors expecting to retire around the year 2070 and who are likely to stop making new investments in the Fund at that time. The Fund is designed for an investor who plans to withdraw the value of the investor's account gradually following that date. The Adviser seeks to optimize the Fund's “glide path” for the wealth accumulation, wealth preservation, and income generation phases of retirement planning and includes adjustments in the critical years immediately preceding and following the retirement date. For example, a Fund with a target retirement date far into the future will typically invest a greater portion of its assets in asset classes with higher risk profiles and the potential for higher returns. As the target date for the Fund approaches, the Adviser will adjust the asset allocation and risk profile of the Fund – its glide path – to what is generally seen to be a more conservative approach to reduce (but not to eliminate) risk by increasing the allocation to asset classes that have historically been subject to lower levels of volatility. A fund intended for investors who have already achieved retirement age would typically invest a greater portion of its assets in bonds and cash items, with a relatively smaller allocation to equity securities.

The Underlying Funds employ a wide array of investment styles. For example, the Underlying Funds can buy and sell common stocks of companies of any size, corporate bonds of varying credit quality, U.S. government and agency bonds, mortgage- and asset-backed securities, commodities, real estate and money market instruments. They may hold U.S. or non-U.S. investments. The Underlying Funds may use derivative instruments of any kind, including futures contracts, forward currency contracts, credit default swaps, interest rate swaps and commodities-related derivatives. Derivatives may be used by an Underlying Fund for hedging or risk management purposes, as a substitute for direct investment, or otherwise to seek to enhance the Underlying Fund's total return.

The glide path depicted in the chart below shows how the Fund's strategic target allocations among asset classes are expected generally to place more emphasis on fixed income investments and less on equity investments as the target retirement date approaches.

The glide path shows the Fund's long term strategic target allocations. The Fund's actual allocations may differ. The Adviser periodically reviews the Fund's target asset allocations and may, at any time, in its discretion, change the target asset allocations or deviate from the target asset allocations when it believes doing so is appropriate to pursue the Fund's investment objective. The glide path is presented only as an illustration of how the process of re-allocation occurs as the Fund approaches its target date.

The following table shows the Fund's strategic target allocations to the Underlying Funds as of the date of this Prospectus.

Underlying Funds	Target Retirement 2070 Fund
State Street Equity 500 Index II Portfolio	____ %
State Street Small/Mid Cap Equity Index Portfolio	____ %
State Street Global All Cap Equity ex-U.S. Index Portfolio	____ %
State Street Aggregate Bond Index Portfolio	____ %
SPDR Bloomberg 1-10 Year TIPS ETF	____ %
SPDR Bloomberg High Yield Bond ETF	____ %
SPDR Dow Jones Global Real Estate ETF	____ %
SPDR Portfolio Long Term Treasury ETF	____ %
SPDR Portfolio Short Term Treasury ETF	____ %
SPDR Portfolio Short Term Corporate Bond ETF	____ %

may modify the selection of Underlying Funds from time to time, and may invest in other Underlying Funds, including any Underlying Funds that may be created in the future. The table is presented for illustrative purposes only. More current information regarding the Fund's allocations may be available on its website: www.ssga.com.

Principal Risks

The Fund is subject to the following principal risks. You could lose money by investing in the Fund. Certain risks relating to instruments and strategies used in the management of the Fund are placed first. The significance of any specific risk to an investment in the Fund will vary over time, depending on the composition of the Fund's portfolio, market conditions, and other factors. You should read all of the risk information presented below carefully, because any one or more of these risks may result in losses to the Fund. An investment in the Fund is subject to investment risks, including possible loss of principal, is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund may not achieve its investment objective. An investment in the Fund is not guaranteed, and you may experience losses, including losses near, at, or after the target date. There is no guarantee that the Fund will provide adequate portfolio growth or income at and through your retirement. The Fund is not intended to be a complete investment program, but rather is intended for investment as part of a diversified investment portfolio. Investors should consult their own advisers as to the role of the Fund in their overall investment programs. Except as otherwise stated, references in this section to “the Fund” or “a Fund” may relate to the Fund, one or more Underlying Funds, or both. The risks described below may arise out of the Fund's direct investments or the Fund's investments in one or more of the Underlying Funds. All or a portion of the Underlying Funds are managed pursuant to a passive investment strategy, while the Fund is managed pursuant to an active investment strategy. You will find additional information about each Underlying Fund's risks in its prospectus and SAI.

Asset Allocation Risk: The Fund's investment performance depends upon the successful allocation by the Adviser of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Adviser's allocation techniques and decisions will produce the desired results.

Risk of Investment in Other Pools: When the Fund invests in another pooled investment vehicle, it is exposed to the risk that the other pool will not perform as expected and is exposed indirectly to all of the risks applicable to an investment in such other pool. The investment policies of the other pool may not be the same as those of the Fund; as a result, an investment in the other pool may be subject to additional or different risks than those to which the Fund is typically subject. The Fund bears its proportionate share of the fees and expenses of any pool in which it invests. The Adviser or an affiliate may serve as investment adviser to a pool in which the Fund may invest, leading to potential conflicts of interest. It is possible that other clients of the Adviser or its affiliates will purchase or sell interests in a pool sponsored or managed by the Adviser or its affiliates at prices and at times more favorable than those at which the Fund does so.

Target Date Assumptions Risk: This is the risk that assumptions and forecasts used by the Adviser in developing the Fund's asset allocation glide path are not in line with actual future investment returns and participant savings activities, which could result in losses near, at, or after the target date year or could result in the Fund not providing adequate income at and through retirement.

Longevity Risk: This is the risk that you will outlive your retirement assets.

Below Investment-Grade Securities Risk: Lower-quality debt securities (“high yield” or “junk” bonds) are considered predominantly speculative, and can involve a substantially greater risk of default than higher quality debt securities. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. They can be illiquid, and their values can have significant volatility and may decline significantly over short periods of time. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general.

Commodities Risk: Commodity prices can have significant volatility, and exposure to commodities can cause the net asset value (“NAV”) of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them.

Counterparty Risk: The Fund will be subject to credit risk with respect to the counterparties with which the Fund enters into derivatives contracts, repurchase agreements, reverse repurchase agreements, and other transactions. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, or to recover collateral posted to the counterparty, resulting in a loss to the Fund. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty.

Currency Risk: The value of the Fund's assets may be affected favorably or unfavorably by currency exchange rates, currency exchange control regulations, and delays, restrictions or prohibitions on the repatriation of foreign currencies. Foreign currency exchange rates may have significant volatility, and changes in the values of foreign currencies against the U.S. dollar may result in substantial declines in the values of the Fund's assets denominated in foreign currencies.

Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments, or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. High levels of inflation and/or a significantly changing interest rate environment can lead to heightened levels of volatility and reduced liquidity.

Depositary Receipts Risk: Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. To the extent the Fund invests in depositary receipts based on securities included in the Index, such differences in prices may increase index tracking risk.

Derivatives Risk: Derivative transactions can create investment leverage and may have significant volatility. It is possible that a derivative transaction will result in a much greater loss than the principal amount invested, that changes in the value of a derivative transaction may not correlate perfectly with the underlying asset, and that the Fund may not be able to close out a derivative transaction at a favorable time or price. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. A derivatives transaction may not behave in the manner anticipated by the Adviser or may not have the effect on the Fund anticipated by the Adviser.

Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, less stringent investor protection and disclosure standards, less developed public health systems, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargo, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at

a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries.

Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Geographic Focus Risk: The performance of a fund that invests significantly in one or more countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the fund invests, and may be more volatile than the performance of a fund that does not invest significantly in such countries or regions.

Income Risk: The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates.

Indexing Strategy/Index Tracking Risk: The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index and, consequently, the performance, volatility, and risk of the Fund. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, generally as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to replicate the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index.

Inflation Risk: Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the values of a fund's assets can decline. Inflation rates may change frequently and drastically as a result of various factors and the Fund's investments may not keep pace with inflation, which may result in losses to Fund investors or adversely affect the real value of shareholders' investments in the Fund. Recently, inflation levels have been at their highest point in nearly 40 years, and the Federal Reserve has begun an aggressive campaign to raise certain benchmark interest rates in an effort to combat inflation. As such, fixed income securities markets may experience heightened levels of interest rate volatility and liquidity risk.

Inflation-Indexed Securities Risk: The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser.

IPO Risk: The Fund may at times have the opportunity to invest in securities offered in initial public offerings (“IPOs”). IPOs involve companies that have no public operating history and therefore entail more risk than established public companies. The prices of securities offered in IPOs can have significant volatility and the Fund may lose money on an investment in such securities. IPO investments in which other clients of the Adviser invest may not be made available to the Fund.

Large-Capitalization Securities Risk: Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies. Larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial,

or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies.

Large Shareholder Risk: To the extent a large proportion of the shares of the Fund are held by a small number of shareholders (or a single shareholder), including funds or accounts over which the Adviser has investment discretion, the Fund is subject to the risk that these shareholders will purchase or redeem Fund Shares in large amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser. These transactions could adversely affect the ability of the Fund to conduct its investment program.

Liquidity Risk: Lack of a ready market, stressed market conditions, or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. Illiquidity of the Fund's holdings may also limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid investments and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector.

Management Risk: The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.

Modeling Risk: The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. There can be no assurance that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors.

Mortgage-Related and Other Asset-Backed Securities Risk: Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed-income investments. The liquidity of mortgage-related and asset-backed securities may change over time. During periods of falling interest rates, mortgage- and asset-backed securities may be called or prepaid, which may result in the Fund having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of mortgage- and asset-backed securities may extend, which may lock in a below-market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, and the underlying assets or collateral may be insufficient if the issuer defaults.

Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent that the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign

government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market.

Real Estate Sector Risk: An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property.

REIT Risk: Real estate investment trusts (“REITs”) are subject to the risks associated with investing in the securities of real property companies. In particular, REITs may be affected by changes in the values of the underlying properties that they own or operate. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets. A variety of economic and other factors may adversely affect a lessee's ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated in protecting its investments. In addition, a REIT could fail to qualify for favorable regulatory treatment.

Restricted Securities Risk: The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws. There can be no assurance that a trading market will exist at any time for any particular restricted security. Limitations on the resale of these securities may have an adverse effect on their marketability, and may prevent the Fund from disposing of them promptly at reasonable prices. The Fund may have to bear the expense of registering the securities for resale and the risk of substantial delays in effecting the registration. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility.

Small-, Mid- and Micro-Capitalization Securities Risk: The securities of small-, mid- and micro-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of smaller issuers may be illiquid or may be restricted as to resale, and their values may have significant volatility. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-, mid- and micro-capitalization companies could trail the returns on investments in securities of larger companies.

Unconstrained Sector Risk: The Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. Greater investment focus on one or more sectors or industries increases the potential for volatility and the risk that events negatively affecting such sectors or industries could reduce returns, potentially causing the value of the Fund's Shares to decrease, perhaps significantly.

U.S. Government Securities Risk: Certain U.S. government securities are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury, are not supported by the full faith and credit of the U.S. government, and involve increased credit risks.

U.S. Treasury Obligations Risk: U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline.

Valuation Risk: Some portfolio holdings, potentially a large portion of the Fund's investment portfolio, may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Investors who purchase or redeem Fund Shares on days when the Fund is holding fair-valued investments may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Fund had not fair-valued the holding(s) or had used a different valuation methodology.

When-Issued, TBA and Delayed Delivery Securities Risk: The Fund may purchase securities on a when-issued, to-be-announced (“TBA”) or delayed delivery basis and may purchase securities on a forward commitment basis. The purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchase of securities on a when-issued, TBA, delayed delivery, or forward commitment basis may give rise to investment leverage, and may result in increased volatility of the Fund's NAV. Default by, or bankruptcy of, a counterparty to a when-issued, TBA or delayed delivery transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. The Financial Industry Regulatory Authority, Inc. (“FINRA”) imposes mandatory margin requirements for certain types of when-issued, delayed delivery or forward commitment transactions, and effective May 22, 2024, such requirements will extend to TBA transactions, with limited exceptions. Such transactions require mandatory collateralization which may increase the cost of such transactions and impose added operational complexity.

Performance

Additional Information About Investment Objectives, Principal Strategies and Risks

Investment Objective

The State Street Institutional Investment Trust's (the “Trust”) Board of Trustees (the “Board”) may change the Fund's investment strategies and other policies without shareholder approval, except as otherwise indicated. The Board may change the Fund's investment objective without shareholder approval.

Principal Investment Strategies

The Adviser invests the Target Retirement 2070 Fund among Underlying Funds according to a proprietary asset allocation. The Fund's name refers to the approximate retirement year of the investors for whom the Fund's asset allocation strategy is intended. As the target date for the Fund approaches, the Adviser will adjust the asset allocation and risk profile of the Fund – its glide path – to a what is generally seen to be a more conservative approach to reduce (but not eliminate) risk by increasing the allocation to asset classes that have historically been subject to lower levels of volatility. For example, since the Fund has a target retirement date far into the future, the Fund will typically invest a greater portion of its assets in asset classes with higher risk profiles and the potential for higher returns. By contrast, the State Street Target Retirement Fund (the “Retirement Fund”) is intended for investors in their retirement years. The Adviser allocates the Fund's assets according to a target asset allocation that emphasizes fixed income funds but also includes an allocation to equity and certain other funds.

When the target asset allocation of the Fund matches the Retirement Fund's target asset allocation, generally five years after the Fund's target retirement date (as shown in the glide path above), it is expected that the Fund will be combined with the Retirement Fund, and the Fund's shareholders will become shareholders of the Retirement Fund. This may be done without a vote of shareholders if the Trustees determine at the time of the proposed combination that combining the Fund and the Retirement Fund is in the best interests of the Fund, the Retirement Fund and their shareholders.

The Adviser intends to manage the Target Retirement 2070 Fund according to the Fund's target asset allocation strategy, and does not intend to trade actively among Underlying Funds or to attempt to capture short-term market opportunities as primary activities. The Adviser may modify the target asset allocation strategy or the selection of Underlying Funds for the Target Retirement 2070 Fund from time to time, and may invest in other Underlying Funds, including any Underlying Funds that may be created in the future.

The Target Retirement 2070 Fund will bear a pro rata share of its Underlying Funds' expenses. The Fund also bears all of the risks associated with the investment strategies used by its Underlying Funds.

The tables below set forth the Fund's strategic target allocations to the Underlying Funds as of the date of this Prospectus and show how the Fund's allocations among asset classes are expected generally to become more conservative as the target retirement date approaches (i.e., more emphasis on fixed income and less on equity) by including the strategic target allocations of the State Street Target Retirement Fund, State Street Target Retirement 2020 Fund, State Street Target Retirement 2025 Fund, State Street Target Retirement 2030 Fund, State Street Target Retirement 2035 Fund, State Street Target Retirement 2040 Fund, State Street Target Retirement 2045 Fund, State Street Target Retirement 2050 Fund, State Street Target Retirement 2055 Fund, Street Target Retirement 2060 Fund and State Street Target Retirement 2065 Fund, each a separate series of the Trust not offered by this prospectus.

The Fund's actual allocations are expected to differ over time. The Adviser periodically reviews the Fund's target allocations to underlying investment options and may, at any time, in its discretion, change the target allocations or deviate from the target allocations when it believes doing so is appropriate to pursue the Fund's investment objective. The Adviser may modify the selection of Underlying Funds from time to time, and may invest in other Underlying Funds, including any Underlying Funds that may be created in the future. The tables are presented for illustrative purposes only.

A brief description of the Underlying Funds can be found in Appendix A. Appendix A lists the Underlying Funds that the Fund may utilize as of the date of this Prospectus.

Additional Information About Risks

The Fund is subject to the following principal risks. The risks are described in alphabetical order and not in the order of importance or potential exposure. Except as otherwise stated, references in this section to “the Fund” or “a Fund” may relate to the Fund, one or more Underlying Funds, or both. The risks described below may arise out of the Fund's direct investments or the Fund's investments in one or more of the Underlying Funds.

Asset Allocation Risk. The Fund's investment performance depends upon the successful allocation of the Fund's assets among asset classes, geographical regions, industry sectors, and specific issuers and investments. There is no guarantee that the Fund's allocation techniques and decisions will produce the desired results. It is possible to lose money on an investment in the Fund as a result of these allocation decisions.

Below Investment-Grade Securities Risk. Securities rated below investment-grade and unrated securities of comparable credit quality (commonly known as “high-yield” or “junk” bonds) lack strong investment-grade characteristics, are considered predominantly speculative with respect to the issuer's continuing ability to make principal and interest payments, and are subject to greater levels of credit, liquidity and market risk than higher-rated securities. They can involve a substantially greater risk of default than higher-rated securities, and their values can decline significantly over short periods of time. Issuers of lower-quality debt securities may have substantially greater risk of insolvency or bankruptcy than issuers of higher-quality debt securities. In the event the issuer of a debt security held by the Fund defaults on its payments or becomes insolvent or bankrupt, the Fund may not receive the return it was promised on the investment and could lose its entire investment. The lower ratings of junk bonds reflect a greater possibility that actual or perceived adverse changes in the financial condition of the issuer or in general economic conditions, or an unanticipated rise in interest rates, may impair the ability of the issuer to make payments of interest and principal. If this were to occur, the values of such securities held by the Fund may fall substantially and the Fund could lose some or all of the value of its investment. Lower-quality debt securities tend to be more sensitive to adverse news about the issuer, or the market or economy in general, than higher quality debt securities. The market for lower quality debt securities can be less liquid than for higher quality debt securities, especially during periods of recession or general market decline, which could make it difficult at times for the Fund to sell certain securities at prices used in calculating the Fund's NAV. These securities may have significant volatility.

Call/Prepayment Risk. Call/prepayment risk is the risk that an issuer will exercise its right to pay principal on an obligation held by the Fund earlier than expected or required. This may occur, for example, when there is a decline in interest rates, and an issuer of bonds or preferred stock redeems the bonds or stock in order to replace them with obligations on which it is required to pay a lower interest or dividend rate. It may also occur when there is an unanticipated increase in the rate at which mortgages or other receivables underlying mortgage- or asset-backed securities held by the Fund are prepaid. In any such case, the Fund may be forced to invest the prepaid amounts in lower-yielding investments, resulting in a decline in the Fund's income.

Commodities Risk. Commodity prices can have significant volatility, and exposure to commodities can cause the NAV of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. The values of physical commodities may be affected by changes in overall market movements, real or perceived inflationary trends, commodity index volatility, changes in interest rates or currency exchange rates, population growth and changing demographics, international economic, political and regulatory developments, and factors affecting a particular region, industry or commodity, such as drought, floods, or other weather conditions, livestock disease, changes in storage costs, trade embargoes, competition from substitute products, transportation bottlenecks or shortages, fluctuations in supply and demand, and tariffs. Also, a liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them. The commodity markets are subject to temporary distortions or other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions.

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties with which the Fund enters into derivatives contracts and other transactions such as repurchase agreements or reverse repurchase agreements. The Fund's ability to profit from these types of investments and transactions will depend on the willingness and ability of its counterparty to perform its obligations. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving its counterparty (including recovery of any collateral posted by it) and may obtain only a limited recovery or may obtain no recovery in such circumstances. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty. Under applicable law or contractual provisions, including if the Fund enters into an investment or transaction with a financial institution and such financial institution (or an affiliate of the financial institution) experiences financial difficulties, then the Fund may in certain situations be prevented or delayed from exercising its rights to terminate the investment or transaction, or to realize on any collateral and may result in the suspension of payment and delivery obligations of the parties under such investment or transactions or in another institution being substituted for that financial institution without the consent of the Fund. Further, the Fund may be subject to “bail-in” risk under applicable law whereby, if required by the financial institution's authority, the financial institution's liabilities could be written down, eliminated or converted into equity or an alternative instrument of ownership. A bail-in of a financial institution may result in a reduction in value of some or all of its securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, such Fund may also be similarly impacted.

Credit Risk. Credit risk is the risk that an issuer, guarantor or liquidity provider of a fixed-income security held by the Fund may be unable or unwilling, or may be perceived (whether by market participants, ratings agencies, pricing services or otherwise) as unable or unwilling, to make timely principal and/or interest payments, or to otherwise honor its obligations. It includes the risk that the security will be downgraded by a credit rating agency; generally, lower credit quality issuers present higher credit risks. An actual or perceived decline in creditworthiness of an issuer of a fixed-income security held by the Fund may result in a decrease in the value of the security. It is possible that the ability of an issuer to meet its obligations will decline substantially during the period when the Fund owns securities of the issuer or that the issuer will default on its obligations or that the obligations of the issuer will be limited or restructured.

The credit rating assigned to any particular investment does not necessarily reflect the issuer's current financial condition and does not reflect an assessment of an investment's volatility or liquidity. Securities rated in the lowest category of investment-grade are considered to have speculative characteristics. If a security held by the Fund loses its rating or its rating is downgraded, the Fund may nonetheless continue to hold the security in the discretion of the Adviser. In the case of asset-backed or mortgage-related securities, changes in the actual or perceived ability of the obligors on the underlying assets or mortgages to make payments of interest and/or principal may affect the values of those securities.

Currency Risk. Investments in issuers in different countries are often denominated in currencies other than the U.S. dollar. Changes in the values of those currencies relative to the U.S. dollar may have a positive or negative effect on the values of the Fund's investments denominated in those currencies. The values of other currencies relative to the U.S. dollar may fluctuate in response to, among other factors, interest rate changes, intervention (or failure to intervene) by national governments, central banks, or supranational entities such as the International Monetary Fund, the imposition of currency controls, and other political or regulatory developments. Currency values can decrease significantly both in the short term and over the long term in response to these and other developments. Continuing uncertainty as to the status of the Euro and the Economic and Monetary Union of the European Union (the “EMU”) has created significant volatility in currency and financial markets generally. Any partial or complete dissolution of the EMU, or any continued uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Fund's portfolio investments.

Debt Securities Risk. The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). To the extent that interest rates fall, certain underlying obligations may be paid off substantially faster than originally anticipated. If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities. High levels of inflation and/or a significantly changing interest rate environment can lead to heightened levels of volatility and reduced liquidity.

Depositary Receipts Risk. American Depositary Receipts (“ADRs”) are typically trust receipts issued by a U.S. bank or trust company that evidence an indirect interest in underlying securities issued by a foreign entity. Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”), and other types of depositary receipts are typically issued by non-U.S. banks or financial institutions to evidence an interest in underlying securities issued by either a U.S. or a non-U.S. entity. Investments in non-U.S. issuers through ADRs, GDRs, EDRs, and other types of depositary receipts generally involve risks applicable to other types of investments in non-U.S. issuers. Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. There may be less publicly available information regarding the issuer of the securities underlying a depositary receipt than if those securities were traded directly in U.S. securities markets. Depositary receipts may or may not be sponsored by the issuers of the underlying securities, and information regarding issuers of securities underlying unsponsored depositary receipts may be more limited than for sponsored depositary receipts. The values of depositary receipts may decline for a number of reasons relating to the issuers or sponsors of the depositary receipts, including, but not limited to, insolvency of the issuer or sponsor. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. To the extent the Fund invests in depositary receipts based on securities included in the Index, such differences in prices may increase index tracking risk.

Derivatives Risk. A derivative is a financial contract the value of which depends on, or is derived from, the value of an underlying asset, interest rate, or index. Derivative transactions typically involve leverage and may have significant volatility. It is possible that a derivative transaction will result in a loss greater than the principal amount invested, that changes in the value of a derivative transaction may not correlate perfectly with the underlying asset, and that the Fund may not be able to close out a derivative transaction at a favorable time or price. Risks associated with derivative instruments include potential changes in value in response to interest rate changes or other market developments or as a result of the counterparty's credit quality; the potential for the derivative transaction not to have the effect the Adviser anticipated or a different or less favorable effect than the Adviser anticipated; the failure of the counterparty to the derivative transaction to perform its obligations under the transaction or to settle a trade; possible mispricing or improper valuation of the derivative instrument; imperfect correlation in the value of a derivative with the asset, rate, or index underlying the derivative; the risk that the Fund may be required to post collateral or margin with its counterparty, and will not be able

to recover the collateral or margin in the event of the counterparty's insolvency or bankruptcy; the risk that the Fund will experience losses on its derivatives investments and on its other portfolio investments, even when the derivatives investments may be intended in part or entirely to hedge those portfolio investments; the risks specific to the asset underlying the derivative instrument; lack of liquidity for the derivative instrument, including, without limitation, absence of a secondary trading market; the potential for reduced returns to the Fund due to losses on the transaction and an increase in volatility; the potential for the derivative transaction to have the effect of accelerating the recognition of gain; and legal risks arising from the documentation relating to the derivative transaction.

Emerging Markets Risk. Investments in emerging markets are generally subject to a greater risk of loss than investments in developed markets. This may be due to, among other things, the possibility of greater market volatility, lower trading volume and liquidity, greater risk of expropriation, nationalization, and social, political and economic instability, greater reliance on a few industries, international trade or revenue from particular commodities, less developed accounting, legal and regulatory systems, higher levels of inflation, deflation or currency devaluation, greater risk of market shutdown, and more significant governmental limitations on investment policy as compared to those typically found in a developed market. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited. In addition, issuers (including governments) in emerging market countries may have less financial stability than in other countries. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. There is also the potential for unfavorable action such as embargo and acts of war. As a result, there will tend to be an increased risk of price volatility in investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar. Settlement and asset custody practices for transactions in emerging markets may differ from those in developed markets. Such differences may include possible delays in settlement and certain settlement practices, such as delivery of securities prior to receipt of payment, which increase the likelihood of a “failed settlement.” Failed settlements can result in losses. For these and other reasons, investments in emerging markets are often considered speculative.

Equity Investing Risk. The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer, such as management performance, financial leverage, non-compliance with regulatory requirements, and reduced demand for the issuer's goods or services. The values of equity securities also may decline due to general industry or market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Extension Risk. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower-than-expected principal payments. This may increase the period of time during which an investment earns a below-market interest rate, increase the security's duration and reduce the value of the security. Extension risk may be heightened during periods of adverse economic conditions generally, as payment rates decline due to higher unemployment levels and other factors.

Financial Sector Risk. Financial services companies are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in

value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition.

Geographic Focus Risk. The performance of a fund that invests significantly in one or more countries or geographic regions will be closely tied to market, currency, economic, political, environmental, or regulatory conditions and developments in the countries or regions in which the fund invests, and may be more volatile than the performance of a fund that does not invest significantly in such countries or regions.

Income Risk. The Fund's income may decline due to falling interest rates or other factors. Issuers of securities held by the Fund may call or redeem the securities during periods of falling interest rates, and the Fund would likely be required to reinvest in securities paying lower interest rates. If an obligation held by the Fund is prepaid, the Fund may have to reinvest the prepayment in other obligations paying income at lower rates. A reduction in the income earned by the Fund may limit the Fund's ability to achieve its objective.

Indexing Strategy/Index Tracking Risk. The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities. The Fund will seek to replicate Index returns, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. The Fund generally will buy and will not sell a security included in the Index as long as the security is part of the Index regardless of any sudden or material decline in value or foreseeable material decline in value of the security, even though the Adviser may make a different investment decision for other actively managed accounts or portfolios that hold the security. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index (in absolute terms and by comparison with other indices) and, consequently, the performance, volatility, and risk of the Fund. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index for a number of reasons. For example, the return on the sample of securities purchased by the Fund (or the return on securities not included in the Index) to replicate the performance of the Index may not correlate precisely with the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, either as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to track the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index. Changes in the composition of the Index and regulatory requirements also may impact the Fund's ability to match the return of the Index. The Adviser may apply one or more “screens” or investment techniques to refine or limit the number or types of issuers included in the Index in which the Fund may invest. Application of such screens or techniques may result in investment performance below that of the Index and may not produce results expected by the Adviser. Index tracking risk may be heightened during times of increased market volatility or other unusual market conditions.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the values of the Fund's assets can decline. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy (or expectations that domestic or global economic policies will change), and the Fund's investments may not keep pace with inflation, which may result in losses to Fund investors or adversely affect the real value of shareholders' investments in the Fund. Recently, inflation levels have been at their highest point in nearly 40 years, and the Federal Reserve has begun an aggressive campaign to raise certain benchmark interest rates in an effort to combat inflation. As such, fixed income securities markets may experience heightened levels of interest rate volatility and liquidity risk.

Inflation-Indexed Securities Risk. The principal amount of an inflation-indexed security typically increases with inflation and decreases with deflation, as measured by a specified index. It is possible that, in a period of declining inflation rates, the Fund could receive at maturity less than the initial principal amount of an inflation-indexed security. Although the holders of U.S. TIPS receive no less than the par value of the security at maturity, if the Fund purchases U.S. TIPS in the secondary market whose principal values have previously been adjusted upward and there is a period of subsequent

declining inflation rates, the Fund may receive at maturity less than it invested. Depending on the changes in inflation rates during the period the Fund holds an inflation-indexed security, the Fund may earn less on the security than on a conventional bond. Changes in the values of inflation-indexed securities may be difficult to predict, and it is possible that an investment in such securities will have an effect different from that anticipated by the Adviser. The principal amounts of inflation-indexed securities are typically only adjusted periodically, and changes in the values of the securities may only approximately reflect changes in inflation rates and may occur substantially after the changes in inflation rates in question occur.

Information Technology Sector Risk. Market or economic factors impacting information technology companies could have a major effect on the value of the Fund's investments. The value of stocks of information technology companies is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the information technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

Interest Rate Risk. Interest rate risk is the risk that the securities held by the Fund will decline in value because of increases in market interest rates. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. Debt securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than debt securities with shorter durations. For example, the value of a security with a duration of five years would be expected to decrease by 5% for every 1% increase in interest rates. Falling interest rates also create the potential for a decline in the Fund's income and yield. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments. Variable and floating rate securities also generally increase or decrease in value in response to changes in interest rates, although generally to a lesser degree than fixed-rate securities. A substantial increase in interest rates may also have an adverse impact on the liquidity of a security, especially those with longer durations. Changes in governmental policy, including changes in central bank monetary policy, could cause interest rates to rise rapidly, or cause investors to expect a rapid rise in interest rates. This could lead to heightened levels of interest rate, volatility and liquidity risks for the fixed income markets generally and could have a substantial and immediate effect on the values of the Fund's investments. High levels of inflation and/or a significantly changing interest rate environment can lead to heightened levels of volatility and reduced liquidity.

IPO Risk. The Fund may at times have the opportunity to invest in securities offered in initial public offerings (“IPOs”). IPOs involve companies that have no public operating history and therefore entail more risk than established public companies. The prices of securities offered in IPOs can have significant volatility and the Fund may lose money on an investment in such securities. IPOs may not be available to the Fund at all times, and the Fund may not always invest in IPOs offered to it. Investments in IPOs may have a substantial beneficial effect on the Fund's investment performance. The Fund's investment return earned during a period of substantial investment in IPOs may not be sustained during other periods when the Fund makes more limited, or no, investments in IPOs. There can be no assurance that the Fund will have the opportunity to invest in IPOs that are made available to other clients of the Adviser.

Large-Capitalization Securities Risk. Securities issued by large-capitalization companies may present risks not present in smaller companies. For example, larger companies may be unable to respond as quickly as smaller and mid-sized companies to competitive challenges or to changes in business, product, financial, or other market conditions. Larger companies may not be able to maintain growth at the high rates that may be achieved by well-managed smaller and mid-sized companies, especially during strong economic periods. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies.

Large Shareholder Risk. To the extent a large proportion of the shares of the Fund are highly concentrated or held by a small number of shareholders (or a single shareholder), including funds or accounts over which the Adviser has investment discretion, the Fund is subject to the risk that these shareholders will purchase or redeem Fund shares in large amounts rapidly or unexpectedly, including as a result of an asset allocation decision made by the Adviser. These transactions could adversely affect the ability of the Fund to conduct its investment program. For example, they could require the Fund to sell portfolio securities or purchase portfolio securities unexpectedly and incur substantial transaction costs

and/or accelerate the realization of taxable income and/or gains to shareholders, or the Fund may be required to sell its more liquid portfolio investments to meet a large redemption, in which case the Fund's remaining assets may be less liquid, more volatile, and more difficult to price. The Fund may hold a relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns.

Leveraging Risk. Borrowing transactions, reverse repurchase agreements, certain derivatives transactions, securities lending transactions and other investment transactions such as when-issued, delayed-delivery, or forward commitment transactions may create investment leverage. If the Fund engages in transactions that have a leveraging effect on the Fund's investment portfolio, the value of the Fund will be potentially more volatile and all other risks will tend to be compounded. This is because leverage generally creates investment risk with respect to a larger base of assets than the Fund would otherwise have and so magnifies the effect of any increase or decrease in the value of the Fund's underlying assets. The use of leverage is considered to be a speculative investment practice and may result in losses to the Fund. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The use of leverage may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy repayment, interest payment, or margin obligations.

Liquidity Risk. Liquidity risk is the risk that the Fund may not be able to dispose of investments readily at a favorable time or prices (or at all) or at prices approximating those at which the Fund currently values them. For example, certain investments may be subject to restrictions on resale, may trade in the over-the-counter market or in limited volume, or may not have an active trading market. Illiquid investments may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. It may be difficult for the Fund to value illiquid investments accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Disposal of illiquid investments may entail registration expenses and other transaction costs that are higher than those for liquid investments. The Fund may seek to borrow money to meet its obligations (including among other things redemption obligations) if it is unable to dispose of illiquid investments, resulting in borrowing expenses and possible leveraging of the Fund. In some cases, due to unanticipated levels of illiquidity the Fund may choose to meet its redemption obligations wholly or in part by distributions of assets in-kind.

The term “illiquid investments” for this purpose means securities that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the securities. If any Fund determines at any time that it owns illiquid investments in excess of 15% of its net assets, it will cease to undertake new commitments to acquire illiquid investments until its holdings are no longer in excess of 15% of its NAV, report the occurrence in compliance with Rule 30b1-10 under the 1940 Act and, depending on circumstances, may take additional steps to reduce its holdings of illiquid investments. The SEC has recently proposed rule amendments that, if adopted as proposed, could result in a larger percentage of the Fund's investments being classified as illiquid investments.

Longevity Risk. This is the risk that you will outlive your retirement assets.

Management Risk. The Fund is actively managed. The Adviser's judgments about the attractiveness, relative value, or potential appreciation of a particular sector, security, commodity or investment strategy may prove to be incorrect, and may cause the Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

Market Disruption and Geopolitical Risk. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. War, terrorism, and related geopolitical events have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets generally. Likewise, natural and environmental disasters, pandemics and epidemics, and systemic market dislocations may be highly disruptive to economies and markets. Those events, as well as other changes in foreign and domestic economic and political conditions, also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund's investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely affect markets, issuers, and/or foreign exchange rates in other countries, including the U.S. Any partial or complete dissolution of the EMU, or any increased uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Fund's investments. On January 31, 2020, the United Kingdom (“UK”) formally withdrew from the European Union (“EU”) (commonly

known as “Brexit”). An agreement between the UK and the EU governing their future trade relationship became effective January 1, 2021, but critical aspects of the relationship remain unresolved and subject to further negotiation and agreement. There is still considerable uncertainty relating to the potential consequences associated with the exit, how the negotiations for new trade agreements will be conducted, and whether the UK's exit will increase the likelihood of other countries also departing the EU. Brexit may have a significant impact on the UK, Europe, and global economies, which may result in increased volatility and illiquidity, new legal, political, economic and regulatory uncertainties and potentially lower economic growth for these economies that could potentially have an adverse effect on the value of the Portfolios' investments. Any further exits from the EU, or the possibility of such exits, or the abandonment of the euro, may cause additional market disruption globally and introduce new legal and regulatory uncertainties.

Securities and financial markets may be susceptible to market manipulation or other fraudulent trade practices, which could disrupt the orderly functioning of these markets or adversely affect the values of investments traded in these markets, including investments held by the Fund. To the extent the Fund has focused its investments in the market or index of a particular region, adverse geopolitical and other events could have a disproportionate impact on the Fund.

Market Risk. Market prices of investments held by the Fund will go up or down, sometimes rapidly or unpredictably. The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors, including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in actual or perceived creditworthiness of issuers and general market liquidity. Even if general economic conditions do not change, the value of an investment in the Fund could decline if the particular industries, sectors or companies in which the Fund invests do not perform well or are adversely affected by events. Further, legal, political, regulatory and tax changes also may cause fluctuations in markets and securities prices. Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, public health issues, or other events could have a significant impact on the Fund and its investments. Due to the interconnectedness of economies and financial markets throughout the world, if the Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic and financial difficulties, the value and liquidity of the Fund's investments may be negatively affected. A widespread outbreak of an infectious illness, such as COVID-19, and efforts to contain its spread, may result in market volatility, inflation, reduced liquidity of certain instruments, disruption in the trading of certain instruments, and systemic economic weakness. The foregoing could impact the Fund and its investments and result in disruptions to the services provided to the Fund by its service providers.

Additionally, in the Spring of 2023, the shutdown of certain financial institutions raised economic concerns over disruption in the U.S. banking system. There can be no certainty that the actions taken by the U.S. government to strengthen public confidence in the U.S. banking system will be effective in mitigating the effects of financial institution failures on the economy and restoring public confidence in the U.S. banking system.

Market Volatility; Government Intervention Risk. Market dislocations and other external events, such as the failures or near failures of significant financial institutions, dislocations in investment or currency markets, corporate or governmental defaults or credit downgrades, or poor collateral performance, may subject the Fund to significant risk of substantial volatility and loss. Governmental and regulatory authorities have taken, and may in the future take, actions to provide or arrange credit supports to financial institutions whose operations have been compromised by credit market dislocations and to restore liquidity and stability to financial systems in their jurisdictions; the implementation of such governmental interventions and their impact on both the markets generally and the Fund's investment program in particular can be uncertain. Governmental and non-governmental issuers may default on, or be forced to restructure, their debts, and other issuers may face difficulties obtaining credit. Defaults or restructurings by governments or others of their debts could have substantial adverse effects on economies, financial markets, and asset valuations around the world. Federal Reserve or other U.S. or non-U.S. governmental or central bank actions, including interest rate increases or contrary actions by different governments, or investor perception that these efforts are not succeeding, could negatively affect financial markets generally as well as the values and liquidity of certain securities.

Modeling Risk. The Adviser uses quantitative models in an effort to enhance returns and manage risk. Any imperfections, errors or limitations in these models could limit any benefit to the Fund from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those expected or desired by the Adviser. These models may make simplifying assumptions that limit their effectiveness and may draw from historical data that does not adequately identify or reflect factors necessary to an appropriate or useful output. There can be no assurance

that the models will behave as expected in all market conditions. In addition, computer programming used to create quantitative models, or the data on which such models operate, might contain one or more errors. Such errors might never be detected, or might be detected only after the Fund has sustained a loss (or reduced performance) related to such errors.

Mortgage-Related and Other Asset-Backed Securities Risk. Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed income investments. The liquidity of mortgage-related and asset-backed securities may change over time. Mortgage-related securities represent a participation in, or are secured by, mortgage loans. Other asset-backed securities are typically structured like mortgage-related securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include, for example, items such as motor vehicle installment sales or installment loan contracts, leases on various types of real and personal property, and receivables from credit card agreements. During periods of falling interest rates, mortgage-related and other asset-backed securities, which typically provide the issuer with the right to prepay the security prior to maturity, may be prepaid, which may result in the Fund having to reinvest the proceeds in other investments at lower interest rates. During periods of rising interest rates, the average life of mortgage-related and other asset-backed securities may extend because of slower-than expected principal payments. This may lock in a below market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. As a result, mortgage-related and other asset-backed securities may have less potential for capital appreciation during periods of declining interest rates than other debt securities of comparable maturities, although they may have a similar risk of decline in market values during periods of rising interest rates. Prepayment rates are difficult to predict and the potential impact of prepayments on the value of a mortgage-related or other asset-backed security depends on the terms of the instrument and can result in significant volatility. The price of a mortgage-related or other asset-backed security also depends on the credit quality and adequacy of the underlying assets or collateral. Mortgage-related or other asset-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) will generally entail greater credit risk than obligations guaranteed by the U.S. Government. Defaults on the underlying assets, if any, may impair the value of a mortgage-related or other asset-backed security. For some asset-backed securities in which the Fund invests, such as those backed by credit card receivables, the underlying cash flows may not be supported by a security interest in a related asset. Moreover, the values of mortgage-related and other asset-backed securities may be substantially dependent on the servicing of the underlying asset pools, and are therefore subject to risks associated with the negligence or malfeasance by their servicers and to the credit risk of their servicers. In certain situations, the mishandling of related documentation may also affect the rights of securities holders in and to the underlying collateral. There may be legal and practical limitations on the enforceability of any security interest granted with respect to underlying assets, or the value of the underlying assets, if any, may be insufficient if the issuer defaults.

In a “forward roll” transaction, the Fund will sell a mortgage-related security to a bank or other permitted entity and simultaneously agree to purchase a similar security from the institution at a later date at an agreed upon price. The mortgage securities that are purchased will bear the same interest rate as those sold, but generally will be collateralized by different pools of mortgages with different prepayment histories than those sold. The values of such transactions will be affected by many of the same factors that affect the values of mortgage-related securities generally. In addition, forward roll transactions may have the effect of creating investment leverage in the Fund.

Non-U.S. Securities Risk. Investments in securities of non-U.S. issuers (including depositary receipts) entail risks not typically associated with investing in securities of U.S. issuers. Similar risks may apply to securities traded on a U.S. securities exchange that are issued by entities with significant exposure to non-U.S. countries. In certain countries, legal remedies available to investors may be more limited than those available with regard to U.S. investments. Because non-U.S. securities are typically denominated and traded in currencies other than the U.S. dollar, the value of the Fund's assets, to the extent they are non-U.S. dollar denominated, may be affected favorably or unfavorably by currency exchange rates, exchange control regulations, and restrictions or prohibitions on the repatriation of non-U.S. currencies. Income and gains with respect to investments in certain countries may be subject to withholding and other taxes. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the United States. The securities of some non-U.S. entities are less liquid and at times more volatile than securities of comparable U.S. entities, and could become subject to sanctions or embargoes that adversely affect the Fund's investment. Non-U.S. transaction costs, such as brokerage commissions and custody costs may be higher than in the U.S. In addition, there may be a possibility of nationalization or expropriation of assets, imposition of currency exchange controls, confiscatory taxation, and diplomatic developments that could adversely affect the values of the Fund's invest

ments in certain non-U.S. countries. Investments in securities of non-U.S. issuers also are subject to foreign political and economic risk not associated with U.S. investments, meaning that political events (civil unrest, national elections, changes in political conditions and foreign relations, imposition of exchange controls and repatriation restrictions), social and economic events (labor strikes, rising inflation) and natural disasters occurring in a country where the Fund invests could cause the Fund's investments to experience gains or losses.

Real Estate Sector Risk. There are special risks associated with investment in securities of companies engaged in real property markets, including without limitation Real estate investment trusts (“REITs”) and real estate operating companies. An investment in a real property company may be subject to risks similar to those associated with direct ownership of real estate, including, by way of example, the possibility of declines in the value of real estate, losses from casualty or condemnation, and changes in local and general economic conditions, supply and demand, interest rates, environmental liability, zoning laws, regulatory limitations on rents, property taxes, and operating expenses. An investment in a real property company is subject to additional risks, such as poor performance by the manager of the real property company, adverse changes in tax laws, difficulties in valuing and disposing of real estate, and the effect of general declines in stock prices. Some real property companies have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property. Also, the organizational documents of a real property company may contain provisions that make changes in control of the company difficult and time-consuming. As a shareholder in a real property company, the Fund, and indirectly the Fund's shareholders, would bear their ratable shares of the real property company's expenses and would at the same time continue to pay their own fees and expenses.

Reinvestment Risk. Income from the Fund's portfolio may decline when the Fund invests the proceeds from investment income, sales of portfolio securities or matured, traded or called debt obligations. For instance, during periods of declining interest rates, an issuer of debt obligations may exercise an option to redeem securities prior to maturity, forcing the Fund to reinvest the proceeds in lower-yielding securities. A decline in income received by the Fund from its investments is likely to have a negative effect on the yield and total return of the Fund Shares.

REIT Risk. REITs are subject to the risks associated with investing in the securities of real property companies. In particular, REITs may be affected by changes in the values of the underlying properties that they own or operate. Further, REITs are dependent upon specialized management skills, and their investments may be concentrated in relatively few properties, or in a small geographic area or a single property type. REITs are also subject to heavy cash flow dependency and, as a result, are particularly reliant on the proper functioning of capital markets, as well as defaults by borrowers and self-liquidation. A variety of economic and other factors may adversely affect a lessee's ability to meet its obligations to a REIT. In the event of a default by a lessee, the REIT may experience delays in enforcing its rights as a lessor and may incur substantial costs associated with protecting its investments. In addition, a REIT could possibly fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended (the “Code”), or to maintain its exemptions from registration under the U.S. Investment Company Act of 1940, as amended (the “1940 Act”), which could have adverse consequences for the Fund. Investments in REITs are also subject to the risks affecting equity markets generally.

Restricted Securities Risk. The Fund may hold securities that have not been registered for sale to the public under the U.S. federal securities laws pursuant to an exemption from registration. These securities may be less liquid than securities registered for sale to the general public. The liquidity of a restricted security may be affected by a number of factors, including, among others: (i) the creditworthiness of the issuer; (ii) the frequency of trades and quotes for the security; (iii) the number of dealers willing to purchase or sell the security and the number of other potential purchasers; (iv) dealer undertakings to make a market in the security; (v) the nature of any legal restrictions governing trading in the security; and (vi) the nature of the security and the nature of marketplace trades. There can be no assurance that a liquid trading market will exist at any time for any particular restricted security. Also, restricted securities may be difficult to value because market quotations may not be readily available, and the securities may have significant volatility.

Risk of Investment in Other Pools. When the Fund invests in another pooled investment vehicle, it is exposed to the risk that the other pool will not perform as expected. The Fund is exposed indirectly to all of the risks applicable to an investment in such other pool. In addition, lack of liquidity in the underlying pool could result in its value being more volatile than the underlying portfolio of securities, and may limit the ability of the Fund to sell or redeem its interest in the pool at a time or at a price it might consider desirable. The investment policies and limitations of the other pool may not be the same as those of the Fund; as a result, the Fund may be subject to additional or different risks, or may achieve a reduced investment return, as a result of its investment in another pool. If a pool is an exchange-traded fund or other product traded on a securities exchange or otherwise actively traded, its shares may trade at a premium or discount to

their NAV, an effect that might be more pronounced in less liquid markets. The Fund bears its proportionate share of the fees and expenses of any pool in which it invests. The Adviser or an affiliate may serve as investment adviser to a pool in which the Fund may invest, leading to potential conflicts of interest. For example, the Adviser or its affiliates may receive fees based on the amount of assets invested in the pool. Investment by the Fund in the pool may be beneficial to the Adviser or an affiliate in the management of the pool, by helping to achieve economies of scale or enhancing cash flows. Due to this and other factors, the Adviser may have an incentive to invest the Fund's assets in a pool sponsored or managed by the Adviser or its affiliates in lieu of investments by the Fund directly in portfolio securities, or may have an incentive to invest in the pool over a pool sponsored or managed by others. Similarly, the Adviser may have an incentive to delay or decide against the sale of interests held by the Fund in a pool sponsored or managed by the Adviser or its affiliates. It is possible that other clients of the Adviser or its affiliates will purchase or sell interests in a pool sponsored or managed by the Adviser or its affiliates at prices and at times more favorable than those at which the Fund does so.

Settlement Risk. Markets in different countries have different clearance and settlement procedures and in certain markets there have been times when settlements have been unable to keep pace with the volume of transactions. Delays in settlement may increase credit risk to the Fund, limit the ability of the Fund to reinvest the proceeds of a sale of securities, hinder the ability of the Fund to lend its portfolio securities, and potentially subject the Fund to penalties for its failure to deliver to on-purchasers of securities whose delivery to the Fund was delayed. Delays in the settlement of securities purchased by the Fund may limit the ability of the Fund to sell those securities at times and prices it considers desirable, and may subject the Fund to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. The Fund may be required to borrow monies it had otherwise expected to receive in connection with the settlement of securities sold by it, in order to meet its obligations to others. Limits on the ability of the Fund to purchase or sell securities due to settlement delays could increase any variance between the Fund's performance and that of its benchmark index.

Small-, Mid- and Micro-Capitalization Securities Risk. The securities of small-, mid- and micro-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of smaller companies may trade less frequently and in smaller volumes than more widely held securities. The prices of these securities may fluctuate more sharply than those of other securities, and the Fund may experience some difficulty in establishing or closing out positions in these securities at prevailing market prices. There may be less publicly available information about the issuers of these securities or less market interest in these securities than in the case of larger companies, both of which can cause significant price volatility. Some securities of smaller issuers may be illiquid or may be restricted as to resale. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. Returns on investments in securities of small-, mid- and micro-capitalization companies could trail the returns on investments in securities of larger companies.

Target Date Assumption Risk. This is the risk that assumptions and forecasts used by SSGA FM in developing the Fund's asset allocation glide path are not in line with actual future investment returns and participant savings activities, which could result in losses near, at, or after the target date year or could result in the Fund not providing adequate income at and through retirement.

Unconstrained Sector Risk. The Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. When the Fund focuses its investments in a particular industry or sector, financial, economic, business, and other developments affecting issuers in that industry, market, or economic sector will have a greater effect on the Fund than if it had not focused its assets in that industry, market, or economic sector, which may increase the volatility of the Fund. Any such investment focus may also limit the liquidity of the Fund. In addition, investors may buy or sell substantial amounts of the Fund's shares in response to factors affecting or expected to affect an industry, market, or economic sector in which the Fund focuses its investments, resulting in extreme inflows or outflows of cash into and out of the Fund. Such extreme cash inflows or outflows might affect management of the Fund adversely. The Fund may establish or terminate a focus in an industry or sector at any time in the Adviser's discretion and without notice to investors.

U.S. Government Securities Risk. U.S. government securities, such as Treasury bills, notes and bonds and mortgage-backed securities guaranteed by the Government National Mortgage Association (“Ginnie Mae”), are supported by the full faith and credit of the United States; others are supported by the right of the issuer to borrow from the U.S. Treasury; others are supported by the discretionary authority of the U.S. government to purchase the agency's obligations; and still others are supported only by the credit of the issuing agency, instrumentality, or enterprise. Although U.S. government-sponsored enterprises such as the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal National Mortgage Association (“Fannie Mae”) may be chartered or sponsored by Congress, they are not funded by Congressional appropriations, and their securities are not issued by the U.S. Treasury nor supported by the full faith and credit of the U.S. government. There is no assurance that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so. In addition, certain governmental entities have been subject to regulatory scrutiny regarding their accounting policies and practices and other concerns that may result in legislation, changes in regulatory oversight and/or other consequences that could adversely affect the credit quality, availability, or investment character of securities issued by these entities. The value and liquidity of U.S. government securities may be affected adversely by changes in the ratings of those securities. Securities issued by the U.S. Treasury historically have been considered to present minimal credit risk. The downgrade in the long-term U.S. credit rating by at least two major rating agencies has introduced greater uncertainty about the ability of the U.S. to repay its obligations. Further credit rating downgrades or a U.S. credit default could decrease the value and increase the volatility of the Fund's investments.

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury obligations to decline. The total public debt of the United States as a percent of gross domestic product grew rapidly after the financial crisis of 2008 and has remained at a historically high level. Although high debt levels do not necessarily indicate or cause economic problems, they may create certain systemic risks if sound debt management practices are not implemented. A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and cause a country to sell additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that a government will not be able to make principal or interest payments when they are due. In the worst case, unsustainable debt levels can cause a decline in the value of the dollar (which may lead to inflation), and can prevent the U.S. government from implementing effective countercyclical fiscal policy in economic downturns. On August 5, 2011, Standard & Poor's Ratings Services downgraded U.S. Treasury securities from AAA rating to AA+ rating. Standard & Poor's Ratings Services stated that its decision was prompted by its view on the rising public debt burden and its perception of greater policymaking uncertainty. Fitch downgraded its rating of U.S. Treasury securities in August 2023. A downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and have a substantial negative effect on the U.S. economy. Any additional downgrades of U.S. Treasury securities from ratings agencies may cause the value of the Fund's U.S. Treasury obligations to decline. In recent years, impasses in Congress regarding the federal budget have caused repeated temporary Federal government shutdowns. While Congress has temporarily suspended the debt limit from time to time, the risks that the U.S. government will not adopt a long-term budget or deficit reduction plan, of one or more additional Federal government shutdowns or of future failures to not increase the Federal government's debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Valuation Risk. Some portfolio holdings, potentially a large portion of the Fund's investment portfolio, may be valued on the basis of factors other than market quotations. This may occur more often in times of market turmoil or reduced liquidity. There are multiple methods that can be used to value a portfolio holding when market quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. Technological issues or other service disruption issues involving third-party service providers may cause the Fund to value its investments incorrectly. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time. Investors who purchase or redeem Fund Shares on days when the Fund is holding fair-valued investments may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the Fund had not fair-valued the holding(s) or had used a different valuation methodology.

When-Issued, TBA and Delayed Delivery Securities Risk. The Fund may purchase securities on a when-issued, to be announced (“TBA”) or delayed delivery basis and may purchase securities on a forward commitment basis. The purchase price of the securities is typically fixed at the time of the commitment, but delivery and payment can take place a month or more after the date of the commitment. The prices of the securities so purchased or sold are subject to market fluctuations. At the time of delivery of the securities, the value may be more or less than the purchase or sale price. Purchase of securities on a when-issued, TBA, delayed delivery, or forward commitment basis may give rise to investment leverage, and may result in increased volatility of the Fund's net asset value. Default by, or bankruptcy of, a counterparty to a when-issued, TBA or delayed delivery transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. The Financial Industry Regulatory Authority, Inc. imposes mandatory margin requirements for certain types of when-issued, delayed delivery and forward commitment transactions, and effective May 22, 2024, such requirements will extend to TBA transactions, with limited exceptions. Such transactions require mandatory collateralization which may increase the cost of such transactions and impose added operational complexity.

Additional Information About Non-Principal Investment Strategies and Risks

Conflicts of Interest Risk. An investment in the Fund will be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to the Fund, such as securities lending agency services, custodial, administrative, bookkeeping, and accounting services, transfer agency and shareholder servicing, securities brokerage services, and other services for which the Fund would compensate the Adviser and/or such affiliates. The Fund may invest in other pooled investment vehicles sponsored, managed, or otherwise affiliated with the Adviser. There is no assurance that the rates at which the Fund pays fees or expenses to the Adviser or its affiliates, or the terms on which it enters into transactions with the Adviser or its affiliates will be the most favorable available in the market generally or as favorable as the rates the Adviser or its affiliates make available to other clients. Because of its financial interest, the Adviser will have an incentive to enter into transactions or arrangements on behalf of the Fund with itself or its affiliates in circumstances where it might not have done so in the absence of that interest, provided that the Adviser will comply with applicable regulatory requirements.

The Adviser and its affiliates serve as investment adviser to other clients and may make investment decisions that may be different from those that will be made by the Adviser on behalf of the Fund. For example, the Adviser may provide asset allocation advice to some clients that may include a recommendation to invest in or redeem from particular issuers while not providing that same recommendation to all clients invested in the same or similar issuers. The Adviser may (subject to applicable law) be simultaneously seeking to purchase (or sell) investments for the Fund and to sell (or purchase) the same investment for accounts, funds, or structured products for which it serves as asset manager, or for other clients or affiliates. The Adviser and its affiliates may invest for clients in various securities that are senior, pari passu or junior to, or have interests different from or adverse to, the securities that are owned by the Fund. The Adviser or its affiliates, in connection with its other business activities, may acquire material nonpublic confidential information that may restrict the Adviser from purchasing securities or selling securities for itself or its clients (including the Fund) or otherwise using such information for the benefit of its clients or itself.

The foregoing does not purport to be a comprehensive list or complete explanation of all potential conflicts of interests which may affect the Fund. The Fund may encounter circumstances, or enter into transactions, in which conflicts of interest that are not listed or discussed above may arise.

Cybersecurity Risk. With the increased use of technologies such as the Internet and the dependence on computer systems to perform business and operational functions, funds (such as the Fund) and their service providers (including the Adviser) may be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions. In addition, the global spread of COVID-19 caused the Fund and its service providers to implement business continuity plans, including widespread use of work-from-home arrangements. Furthermore, geopolitical tensions may have increased the scale and sophistication of deliberate cybersecurity attacks, particularly those from nation-states or from entities with nation-state backing. In general, cyber-attacks are deliberate, but unintentional events may have similar effects. Cyber-attacks include, among others, stealing or corrupting data maintained online or digitally, preventing legitimate users from accessing information or services on a website, releasing confidential information without authorization, and causing operational disruption. Successful cyber-attacks against, or security breakdowns of, the Fund, the Adviser or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect the Fund or its shareholders. For instance, cyber-attacks or technical malfunctions may interfere with the processing of shareholder or other transactions, affect the Fund's ability to calculate its NAV, cause the release of private shareholder infor

mation or confidential Fund information, impede trading, cause reputational damage, and subject the Fund to regulatory fines, penalties or financial losses, reimbursement or other compensation costs, and additional compliance costs. Cyber-attacks or technical malfunctions may render records of Fund assets and transactions, shareholder ownership of Fund Shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. The Fund may also incur substantial costs for cybersecurity risk management in order to prevent cyber incidents in the future. The Fund and its shareholders could be negatively impacted as a result. While the Adviser has established business continuity plans and systems designed to minimize the risk of cyber-attacks through the use of technology, processes and controls, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, given the evolving nature of this threat. The Fund relies on third-party service providers for many of its day-to-day operations, and will be subject to the risk that the protections and protocols implemented by those service providers will be ineffective to protect the Fund from cyber-attack. The Adviser does not control the cybersecurity plans and systems put in place by third-party service providers, and such third-party service providers may have limited indemnification obligations to the Adviser or the Fund. Similar types of cybersecurity risks or technical malfunctions also are present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund's investment in such securities to lose value.

Index Construction Risk. A security included in an Index may not exhibit the characteristic or provide the specific exposure for which it was selected and consequently the Fund's holdings may not exhibit returns consistent with that characteristic or exposure.

Index Licensing Risk. It is possible that the license under which the Adviser or the Fund is permitted to replicate or otherwise use an Index will be terminated or may be disputed, impaired or cease to remain in effect. In such a case, the Adviser may be required to replace the Index with another index which it considers to be appropriate in light of the investment strategy of the Fund. The use of any such substitute index may have an adverse impact on the Fund's performance. In the event that the Adviser is unable to identify a suitable replacement for the Index, it may determine to terminate the Fund.

Money Market Fund Investment Risk. An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. It is possible that such a money market fund will issue and redeem shares at $1.00 per share at times when the fair value of the money market fund's portfolio per share is more or less than $1.00. The SEC has adopted amendments to money market fund regulation that, among other things, increase the daily and weekly liquid asset requirements. Such amendments may limit the Fund's investment flexibility and reduce its ability to generate returns. None of State Street Corporation, State Street Bank and Trust Company (“State Street”), State Street Global Advisors, Inc. (“SSGA”), SSGA Funds Management, Inc. or their affiliates (“State Street Entities”) guarantee the value of an investment in a money market fund at $1.00 per share. Investors should have no expectation of capital support to a money market fund from State Street Entities. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. A money market fund may be permitted or required to impose redemption fees during times of market stress.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities. Fund turnover generally involves a number of direct and indirect costs and expenses to the Fund, including, for example, brokerage commissions, dealer mark-ups and bid/asked spreads, and transaction costs on the sale of securities and reinvestment in other securities. The costs related to increased portfolio turnover have the effect of reducing the Fund's investment return, and the sale of securities by the Fund may result in the realization of taxable capital gains, including short-term capital gains, which are taxed to individuals as ordinary income.

Securities Lending Risk. The Fund may lend portfolio securities in an amount not to exceed 40% of the value of its net assets. For these purposes, net assets shall exclude the value of all assets received as collateral for the loan. Such loans may be terminated at any time. Any such loans must be continuously secured by collateral (either cash or other obligations as may be permitted under the Fund's securities lending program) maintained on a current basis in an amount at

least equal to the market value of the securities loaned by the Fund, marked to market each trading day. The Fund will receive the amount of all dividends, interest and other distributions on the loaned securities; however, the borrower has the right to vote the loaned securities. The Fund will call loans to vote proxies if a material issue affecting the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. Should the borrower of the securities fail financially, the Fund may experience delays in recovering the securities or exercising its rights in the collateral. Loans are made only to borrowers that are deemed by the securities lending agent to be of good financial standing. In a loan transaction, the Fund will also bear the risk of any decline in value of securities acquired with cash collateral. The Fund expects to invest cash collateral in a pooled investment vehicle advised by the Adviser (e.g., a mutual fund or exchange-traded fund). With respect to index funds, to the extent the collateral provided or investments made with cash collateral differ from securities included in the relevant Index, such collateral or investments may have a greater risk of loss than the securities included in the Index. In addition, the Fund will be subject to the risk that any income generated by reinvesting cash collateral is lower than any fees the Fund has agreed to pay a borrower.

Temporary Defensive Positions. In response to actual or perceived adverse market, economic, political, or other conditions, the Fund may (but will not necessarily), without notice, depart from its principal investment strategies by temporarily investing for defensive purposes. Temporary defensive positions may include, but are not limited to, cash, cash equivalents, U.S. government securities, repurchase agreements collateralized by such securities, money market funds, and high-quality debt investments. While investing defensively, the Fund may maintain a substantial portion of its assets in cash, on which the Fund may earn little if any income. If the Fund invests for defensive purposes, it may not achieve its investment objective. In addition, the defensive strategy may not work as intended.

Portfolio Holdings Disclosure

The Fund's portfolio holdings disclosure policy is described in the Statement of Additional Information (“SAI”).

The portfolio managers within the team work together in a cohesive manner to develop and enhance techniques that drive the investment process for the respective investment strategy. This approach requires portfolio managers to share a variety of responsibilities, including investment strategy and analysis, while retaining responsibility for the implementation of the strategy within any particular portfolio. The approach also enables the team to draw upon the resources of other groups within SSGA. The portfolio management team is overseen by the SSGA Investment Committee.

Shareholders are not parties to any such contractual arrangements or intended beneficiaries of those contractual arrangements, and those contractual arrangements are not intended to create in any shareholder any right to enforce them directly against the service providers or to seek any remedy under them directly against the service providers.

This Prospectus provides information concerning the Trust and the Fund that you should consider in determining whether to purchase shares of the Fund. Neither this Prospectus, nor the related SAI, is intended, or should be read, to be or to give rise to an agreement or contract between the Trust or the Fund and any investor, or to give rise to any rights in any shareholder or other person other than any rights under federal or state law that may not be waived.

Shareholder Information

Determination of Net Asset Value

The Fund determines its NAV per share once each business day as of the scheduled close of regular trading on the New York Stock Exchange (the “NYSE”). Pricing does not occur on NYSE holidays. A business day is one on which the NYSE is open for regular trading. The Federal Reserve is closed on certain holidays on which the NYSE is open. These holidays are Columbus Day and Veterans Day. On these holidays, you will not be able to purchase shares by wiring Federal Funds because Federal Funds wiring does not occur on days when the Federal Reserve is closed. In unusual circumstances, such as an emergency or an unscheduled close or halt of trading on the NYSE, the time at which share prices are determined may be changed. The NAV per share is based on the market value of the investments held in the Fund. The NAV of each class of the Fund's Shares is calculated by dividing the value of the assets of the Fund attributable to that class less the liabilities of the Fund attributable to that class by the number of shares in the class outstanding. As noted in this Prospectus, the Fund may invest in securities listed on foreign exchanges, or otherwise traded in a foreign market, and those securities may trade on weekends or other days when the Fund does not price its shares. Consequently, the NAV of the Fund's Shares may change on days when shareholders are not able to purchase or redeem the Fund's Shares. Purchase and redemption orders for Fund Shares are processed, respectively, at the NAV next determined after the Fund accepts a purchase order or receives a redemption request in good form. The Fund values each security or other investment pursuant to guidelines adopted by the Board. The Board has appointed the Adviser as the valuation designee to fair value securities or other investments pursuant to procedures approved by the Fund's Board, under certain limited circumstances. For example, fair value pricing may be used when market quotations are not read

ily available or reliable, such as when (i) trading for a security is restricted; or (ii) a significant event, as determined by the Adviser, that may affect the value of one or more securities or other investments held by the Fund occurs after the close of a related exchange but before the determination of the Fund's NAV. Attempts to determine the fair value of securities or other investments introduce an element of subjectivity to the pricing of securities or other investments. As a result, the price of a security or other investment determined through fair valuation techniques may differ from the price quoted or published by other sources and may not accurately reflect the price the Fund would have received had it sold the investment. To the extent that the Fund invests in the shares of other registered open-end investment companies that are not traded on an exchange (mutual funds), such shares are valued at their published NAVs per share as reported by the funds. The prospectuses of these funds explain the circumstances under which the funds will use fair value pricing and the effects of using fair value pricing.

Investing in State Street Institutional Investment Trust Shares

Mutual funds advised by SSGA FM (the “State Street Funds”) and their service providers have a legal obligation to collect from you certain personal information about you at the time you open an account in order to verify your identity and the source of your payment. If you do not provide this information, you may not be able to open an account with the State Street Funds. If the State Street Funds believe that they have uncovered unlawful activity, the State Street Funds and their service providers may close your account and take any action they deem reasonable or required by law. The State Street Funds reserve the right to reject any purchase order.

This section of the Prospectus explains the basics of doing business with the State Street Funds. Carefully read each topic. The policies set forth below regarding the purchase, redemption and exchange of State Street Fund shares are in addition to the “Purchase and Sale of Fund Shares” section contained in the “Fund Summary” portion of this Prospectus. The State Street Funds reserve the right to change the following policies, without notice to shareholders; except that any modification or termination of the exchange privileges described in this Prospectus will be preceded by 60 days' advance notice to shareholders. Please call or check online for current information. Requests for transactions in the State Street Funds will be processed when they are received in “good order.” “Good order” means that the request is in an accurate and complete form, and all applicable documents have been received in such accurate and complete form (including, typically, a signed application and medallion-guaranteed documents), and, for a purchase request, the check or wired funds have cleared.

Purchasing Shares

Choosing a Share Class

The Fund offers three classes of shares through this Prospectus: Class I, Class K and Class R3, available to you subject to the eligibility requirements set forth below.

All classes of the Fund share the same investment objective and investments, but the different share classes have different expense structures and eligibility requirements. The availability of shares of a particular class through a given Financial Intermediary will depend on the policies and procedures of the Financial Intermediary. The Fund, the Distributor, the Adviser and the Transfer Agent do not provide advice or make recommendations regarding Fund share classes and do not verify that you have invested in the share class most appropriate for your investment needs. You should choose the class with the expense structure that best meets your needs and for which you are eligible. Some factors to consider are the amount you plan to invest, the time period before you expect to sell your shares, whether you might invest more money in the Fund in the future, and the nature of your arrangement with a Financial Intermediary. Your investment professional can help you choose a share class that is appropriate for your investment needs.

The chart below summarizes the features of the different share classes. This chart is only a general summary, and you should read the description of the Fund's expenses in the Fund Summary in this Prospectus.

Any applicable minimum purchase amount may be waived for specific investors or types of investors, including, without limitation, retirement plans, employees of State Street Corporation and its affiliates and their families. In the case of shareholders purchasing shares through a Financial Intermediary, the minimum purchase amount may be applied at the level of the Financial Intermediary.

How to Initiate a Purchase Request

Investing in the State Street Funds Through a Financial Intermediary

Please consult your Financial Intermediary to determine which, if any, shares are available through that firm and to learn about other rules that may apply. You may also submit a New Account Application. To open certain types of accounts, such as IRAs, you will be required to submit an account-specific application. If you intend to add certain investor services offered by the State Street Funds, such as Automatic Investment and Withdrawals Plans, you also will be required to submit a Service Option Form. See Service Options. If you are opening an account through a Financial Intermediary, such as a bank or broker, the Financial Intermediary should have the documents that you will need.

Trade Dates-Purchases

The trade date for any purchase request received in good order will depend on the day and time the State Street Funds receive your request, the manner in which you are paying, and the type of fund you are purchasing. Each State Street Fund's NAV is calculated only on business days, that is, those days that the NYSE is open for regular trading. Purchase orders are processed at the NAV next determined after the Fund accepts a purchase order.

For Purchases by Check, Exchange or Wire into all Funds: If the purchase request is received in good order by the State Street Funds on a business day before the close of regular trading on the NYSE (ordinarily 4 p.m., Eastern time), the trade date will be the same day. If the purchase request is received in good order on a business day after the close of regular trading on the NYSE, or on a non-business day, the trade date will be the next business day.

If your purchase request is not in good order, it may be rejected.

For further information about purchase transactions, consult our website at www.ssga.com or see Contacting the State Street Funds.

Your redemption will be executed using the NAV as calculated on the trade date. NAVs are calculated only on days that the NYSE is open for regular trading (a business day). If the redemption request is received in good order by the State Street Funds on a business day before the close of regular trading on the NYSE (ordinarily 4 p.m., Eastern time), the request will be processed the same day using that day's NAV. If the redemption request is received in good order on a business day after the close of regular trading on the NYSE, or on a non-business day, the request will be processed the next business day.

How to Receive Redemption Proceeds

Regardless of the method the Fund uses to make a redemption payment, the Fund typically expects to pay out redemption proceeds on the next business day after a redemption request is received in good order. If you purchased State Street Fund Shares by check or an automatic investment program and you elect to redeem shares within 15 days of the purchase, you may experience delays in receiving redemption proceeds. In this case, the State Street Funds generally will postpone sending redemption proceeds until it can verify that the check or automatic investment program investment has been collected, but in no event will this delay exceed 15 days. There will be no such delay for redemptions following purchases paid by federal funds wire or by bank cashier's check, certified check or treasurer's check. The State Street Funds reserve the right to pay for redeemed shares within seven days after receiving a redemption order if, in the judgment of the Adviser, an earlier payment could adversely affect the Fund. The State Street Funds reserve the right to suspend the right of shareholder redemption or postpone the date of payment for more than seven days to the extent permitted by the 1940 Act.

The Transfer Agent may temporarily delay for more than seven days the disbursement of redemption proceeds from the Fund account of a “Specified Adult” (as defined in Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 2165) based on a reasonable belief that financial exploitation of the Specified Adult has occurred, is occurring, has been attempted, or will be attempted, subject to certain conditions.

Under normal circumstances, the Fund expects to meet redemption requests by using cash or cash equivalents in its portfolio and/or selling portfolio assets to generate cash. The Fund also may pay redemption proceeds using cash obtained through borrowing arrangements (including under the Fund's line of credit, which is shared across all registered funds advised by SSGA FM (other than money market funds)) that may be available from time to time.

The right of any investor to receive payment with respect to any redemption may be suspended or the payment of the redemption proceeds postponed beyond 7 days in accordance with Section 22(e) of the 1940 Act and the rules thereunder, including during any period in which the NYSE is closed (other than weekends or holidays) or trading on the NYSE is restricted or if an emergency exists as a result of which disposal by the Fund of securities owned by it is not reasonably practicable or it is not reasonably practicable for the Fund fairly to determine the value of its net assets. In addition, the SEC may by order permit suspension of redemptions for the protection of shareholders of the Fund.

The Fund may pay all or a portion of your redemption proceeds by giving you securities (for example, if the Fund reasonably believes that a cash redemption may have a substantial impact on the Fund and its remaining shareholders). A redemption is generally a taxable event for shareholders, regardless of whether the redemption is satisfied in cash or in kind. You may pay transaction costs (including through the realization of taxable gain) to dispose of the securities, and you may receive less for them than the price at which they were valued for purposes of the redemption. In addition, you will be subject to the market risks associated with such securities until such time as you choose to dispose of the security.

During periods of deteriorating or stressed market conditions, when an increased portion of the Fund's portfolio may be comprised of less liquid investments, or during extraordinary or emergency circumstances, the Fund may be more likely to pay redemption proceeds with cash obtained through short-term borrowing arrangements (if available) or by giving you securities.

By Electronic Bank Transfer. You may have the proceeds of the fund redemption sent directly to a designated bank account. To establish the electronic bank transfer option on an account, you must designate a bank account by completing a special form or filling out the appropriate section of your account registration form. After the option is set up on your account, you can redeem shares by electronic bank transfer on a regular schedule (Automatic Withdrawal Plan) or from time to time. Your redemption request can be initiated by telephone, or by mail.

By Wire. When redeeming shares of a State Street Fund, you may instruct the State Street Funds to wire your redemption proceeds ($1,000 minimum) to a previously designated bank account. Shares will be redeemed from the account on the day that the redemption instructions are received in good order. The wire redemption option is not automatic; you must designate a bank account by completing a special form or filling out the appropriate section of your account registration form. The State Street Funds typically do not charge you a fee for wiring redemption proceeds, although it reserves the right to do so. Your bank may charge a fee for receiving a wire. You are encouraged to check with your bank before initiating any transaction.

By Exchange. You may have the proceeds of a State Street Fund redemption invested directly into shares of another State Street Fund of the same class. You may initiate an exchange by telephone, or by mail.

By Check. You may have the proceeds of a State Street Funds redemption paid by check and sent to the address shown on the State Street Funds registration record, provided that the address on the registration record has not changed within thirty (30) days of the redemption request. The State Street Funds will mail you a redemption check, generally payable to all registered account owners.

Other Redemption Policies that You Should Know

Address Changes. If your address of record has been changed within thirty (30) days of the redemption request, the request must be in writing and bear a medallion guarantee.

Significant/Unusual Economic or Market Activity. During periods of significant or unusual economic or market activity, you may encounter delays attempting to give instructions by phone.

Minimum Account Size. If, due to your redemptions or exchanges, your account balance for the Fund falls below a minimum amount set by the Fund (presently, the minimum initial investment of your selected share class), the Fund may choose to redeem the shares in the account and mail you the proceeds. You will receive 60 days' notice that your account will be closed unless an investment is made to increase the account balance to the required minimum. Failure to bring your account balance to the required minimum within the prescribed period may result in the Fund closing your account at the NAV next determined on the day the account is closed, and mailing the proceeds to you at the address shown on the Fund's records.

Exchanging Shares

An exchange occurs when you use the proceeds from the redemption of shares of one State Street Fund to simultaneously purchase shares of a different State Street Fund. Exchanges may be made within the same class (i.e. Class A shares for Class A shares, Class I shares for Class I shares). Class N shares are also exchangeable for other share classes of State Street Funds and would be subject to the conditions for investing in the other class of shares described in the applicable prospectus. The account holding the original shares must be registered in the same name as the account holding the new shares received in the exchange. You may make exchange requests by telephone, or by mail. See Purchasing Shares and Redeeming Shares above.

Exchanges are subject to the terms applicable to the purchases of the Fund into which you are exchanging. Exchange privileges may not be available for all State Street Funds and may be suspended or rejected. Exchanging shares of a State Street Fund for shares of another fund is a taxable event and may result in capital gain or loss. See Tax Considerations below.

If the NYSE is open for regular trading (generally until 4 p.m. Eastern time, on a business day) at the time an exchange request is received in good order, the trade date generally will be the same day. Please note that the State Street Funds reserve the right to revise or terminate the exchange privilege, limit the amount of any exchange, or reject an exchange, at any time, for any reason; provided, that shareholders will be provided 60 days' advance notice of any modification or termination of the exchange privilege.

Share Class Conversions

You may be able to convert your shares to a different share class of the same Fund that has a lower expense ratio provided that you are eligible to buy that share class and that certain conditions are met. This conversion feature is intended for shares held through a Financial Intermediary offering a fee-based or wrap fee program that has an agreement with SSGA FD specific for this purpose. In such instance, your shares may be automatically converted under certain circumstances. Class N shares of a State Street Fund may be converted to Class I shares of the same State Street Fund. Not all share classes are available through all Financial Intermediaries. If your shares of the Fund are converted to a different share class of the same Fund, the transaction will be based on the respective NAV of each class as of the trade date of the conversion. Consequently, you may receive fewer shares or more shares than originally owned, depending on that day's NAVs. The total value of the initially held shares, however, will equal the total value of the converted shares at the time of conversion. The conversion of shares of one class of the Fund into shares of another class of the same Fund is not taxable for U.S. federal income tax purposes and no gain or loss will be reported on the transaction. See the applicable prospectus for share class information. Please contact your Financial Intermediary regarding the tax consequences of any conversion and for additional information.

Frequent-Trading Limits

Frequent, short-term trading, abusive trading practices and market timing (together, “Excessive Trading”), often in response to short-term fluctuations in the market, are not knowingly permitted by the State Street Funds. The State Street Funds do not accommodate frequent purchases and redemptions of Fund Shares by Fund shareholders. Excessive Trading into and out of a State Street Fund may harm the Fund's performance by disrupting portfolio management strategies and by increasing expenses. These expenses are borne by all Fund shareholders, including long-term investors who do not generate such costs.

Excessive Trading activity is generally evaluated based on roundtrip transactions in an account. A “roundtrip” transaction is defined generally as a purchase or exchange into the Fund followed, or preceded, by a redemption or exchange out of the same Fund within 30 days. A State Street Fund may, in its discretion, determine to apply a time period other than 30 days in connection with identifying roundtrip transactions. Shareholders with one or more roundtrip transactions may, in the discretion of a State Street Fund, be blocked from making additional purchases or exchanges in any State Street Fund for a period of time. A State Street Fund has discretion to determine that action is not necessary if it determines that a pattern of trading is not abusive or harmful to the affected Fund in a material way. Fund size and/or transaction size may be considered in evaluating any roundtrip transaction.

The Board of Trustees of the State Street Funds has adopted a “Market Timing/Excessive Trading Policy” (the “Policy”) to discourage Excessive Trading. Under the Policy, the State Street Funds reserve the right to reject any exchanges or purchase orders by any shareholder engaging in Excessive Trading activities.

As a means to protect each State Street Fund and its shareholders from Excessive Trading:

•

The State Street Funds' transfer agent compiles, monitors and reports account-level information on omnibus and underlying shareholder/participant activity. Depending on the account type, monitoring will be performed on a daily, monthly, quarterly and/or annual basis;

•

The State Street Funds' distributor has obtained information from each Financial Intermediary holding shares in an omnibus account with the State Street Funds regarding whether the Financial Intermediary has adopted and maintains procedures that are reasonably designed to protect the Fund against harmful short-term trading; and

•

With respect to State Street Funds that invest in securities that trade on foreign markets, pursuant to the State Street Funds' fair valuation procedures, pricing adjustments may be made based on information received from a third-party, multi-factor fair valuation pricing service.

The State Street Funds' distributor has detailed procedures that document the transparency oversight and monitoring processes performed by the State Street Funds' transfer agent.

While the State Street Funds attempt to discourage Excessive Trading, there can be no guarantee that it will be able to identify investors who are engaging in Excessive Trading or limit their trading practices. Additionally, frequent trades of small amounts may not be detected. The State Street Funds recognize that it may not always be able to detect or prevent Excessive Trading or other activity that may disadvantage the Fund or its shareholders.

A State Street Fund shareholder's right to purchase shares through an automatic investment plan or redeem shares in full (or in part through a systematic withdrawal plan) are unaffected by Excessive Trading restrictions.

Service Options

Dividend and Capital Gain Distribution Option

You may set up your State Street Fund account to reinvest any dividend or capital gains distribution that you receive as the Fund shareholder into the same or a different State Street Fund, or have any dividend or capital gain distribution paid by check, by wire or by check to a special payee. No interest will accrue on the amounts represented by the uncashed distribution checks. If you have elected to receive distributions by check, and the postal or other delivery service is unable to deliver the checks because of an incorrect mailing address, or if a distribution check remains uncashed for six months, the uncashed distribution and all future distributions will be reinvested at the then-current NAV of the Fund.

Please refer to Dividends, Distributions and Tax Considerations below for additional information.

Automatic Withdrawal Plan

If your account balance is over $10,000, you may request periodic (monthly, quarterly, semi-annually, or annually) automatic cash withdrawals of $100 or more which can be mailed to you or any person you designate, or sent through ACH to your bank (at your selection). Proceeds from such withdrawals will be transmitted to the bank account you designate two business days after the trade is placed or executed automatically. No interest will accrue on the amounts represented by the uncashed redemption check(s). Ask your financial adviser or Financial Intermediary for details.

Telephone Redemptions and Exchanges

You may set up your State Street Fund account so that if you request over the telephone to redeem State Street Fund Shares, the redemption proceeds will automatically be wired to a designated bank account. You also may set up your account to permit the State Street Funds to act on your telephonic instructions to exchange State Street Funds shares or to establish a systematic exchange plan. You may choose the date, the frequency (monthly, quarterly or annually) of systematic exchanges of your shares in one State Street Fund to another State Street Fund of the same share class.

Automatic Investment Plan

Once the initial investment has been accepted, you may make subsequent investments of $100 or more monthly, quarterly or annually by direct deposit by debiting your bank checking or savings account. Once this option has been established, you may call the State Street Funds to make additional automatic purchases, to change the amount of the existing automatic purchase, or to stop it. The State Street Fund reserves the right to cancel your automatic investment plan if any correspondence sent by the Fund is returned by the postal or other delivery service as “undeliverable.”

Additional Shareholder Information

Account Transfers

To effect a change in account registration (for example, to add a new joint owner), a shareholder of a State Street Fund may request to open a new account in the same State Street Fund (referred to as a “transfer”). To effect a transfer, the State Street Funds require a completed and signed new account application, including all necessary additional documents required by the form, and a letter of instruction. The letter of instruction must include the name of the State Street Fund and the original account number, and must be signed by all registered owners of the original account and include a medallion guarantee.

Responsibility for Fraud

The State Street Funds will not be responsible for any account losses because of fraud if we reasonably believe that the person transacting business on an account is authorized to do so. Please take precautions to protect yourself from fraud. Keep your account information private, and immediately review any account statements that we provide to you. It is important that you contact the State Street Funds immediately about any transactions or changes to your account that you believe to be unauthorized.

Right to Change Policies

In addition to the rights expressly stated elsewhere in this Prospectus, the State Street Funds reserve the right, in the future, to:

Alter, add, or discontinue any conditions of purchase (including eligibility requirements), redemption, exchange, service, or privilege at any time;

Accept initial purchases by telephone;

Freeze any account and/or suspend account services if the State Street Funds has received reasonable notice of a dispute regarding the assets in an account, including notice of a dispute between the registered or beneficial account owners, or if we reasonably believe a fraudulent transaction may occur or has occurred;

Temporarily freeze any account and/or suspend account services upon initial notification to the State Street Funds of the death of the shareholder until the State Street Funds receive required documentation in good order;

Alter, impose, discontinue, or waive any redemption fee, account service fee, or other fees charged to a group of shareholders; and

Redeem an account or suspend account privileges, without the owner's permission to do so, in cases of threatening conduct or activity the State Street Funds believe to be suspicious, fraudulent, or illegal.

Changes may affect any or all investors. These actions will be taken when, at the sole discretion of the SSGA FM management, we reasonably believe they are deemed to be in the best interest of the State Street Fund.

Unclaimed Property

Many states have unclaimed property rules that provide for transfer to the state (also known as “escheatment”) of unclaimed property under various circumstances. These circumstances include inactivity (e.g., no owner-initiated contact for a certain period), returned mail (e.g., when mail sent to a shareholder is returned by the post office as undeliverable), or a combination of both inactivity and returned mail. If the Fund's transfer agent identifies property as unclaimed, it will attempt to contact the shareholder, but if that attempt is unsuccessful, the account may be considered abandoned and escheated to the state after the passage of a certain period of time (as required by applicable state law).

It is your responsibility to ensure that you maintain a correct address for your account, and maintain contact in ways such as by contacting the Fund's transfer agent by mail or telephone or accessing your account through the Fund's website, and promptly cashing all checks for dividends, capital gains and redemptions. State requirements for maintaining contact with an account can vary and are subject to change. If you invest in the Fund through a financial intermediary, we encourage you to contact the financial intermediary regarding applicable state unclaimed property laws. The Fund, the transfer agent and the distributor will not be liable to shareholders or their representatives for good faith compliance with state unclaimed property laws. Please check your state's unclaimed or abandoned property website for specific information.

If you are a resident of the state of Texas, you may designate a representative to receive escheatment notifications by completing and submitting a designation form, which you can find on the website of the Texas Comptroller. Designating such a representative may be beneficial, since Texas law provides that the escheatment period will cease if the representative, after receiving an escheatment notification regarding your account, communicates knowledge of your location and confirms that you have not abandoned your account. You can mail a completed designation form to the Fund (if you hold shares directly with the Fund) or to your financial intermediary (if you do not hold shares directly with the Fund).

Dividends, Distributions and Tax Considerations

Dividends of investment income and capital gain distributions of the Fund will be declared and paid at least annually. Any investment income and capital gains that have not been distributed by December of each calendar year are generally distributed at such time. When the Fund distributes investment income or capital gains, the NAV per share is reduced by the amount of the distribution.

Distribution Options. You can choose from four different distribution options as indicated on the application:

•

Reinvestment Option—Dividends and capital gain distributions will be automatically reinvested in additional shares of the Fund. If you do not indicate a choice on the application, this option will be automatically assigned.

•

Income-Earned Option—Capital gain distributions will be automatically reinvested, but a check, direct deposit or wire will be sent for each dividend distribution.

•

Cash Option—A check, wire or direct deposit will be sent for each dividend and capital gain distribution.

•

Direct Dividends Option—Dividends and capital gain distributions will be automatically invested in another identically registered State Street Fund of the same share class.

If you have elected to receive distributions by check, and the postal or other delivery service is unable to deliver the checks because of an incorrect mailing address, or if a distribution check remains uncashed for six months, the uncashed distribution and all future distributions will be reinvested at the then-current net asset value of the Fund.

Dividend Policy Upon Purchase. A shareholder will receive a dividend or capital gain distribution only if the shareholder purchased Fund Shares by the close of the record date of such dividend or capital gain distribution.

Delivery of Documents to Accounts Sharing an Address

To reduce expenses, we may mail only one copy of the Fund's Prospectus and the annual and semi-annual report to those addresses shared by two or more accounts. If you wish to receive individual copies of these documents, please call us at (800) 997-7327, or contact your financial institution. We will begin sending you individual copies thirty (30) days after receiving your request.

Tax Considerations

The following discussion is a summary of some important U.S. federal income tax considerations generally applicable to an investment in the Fund. Your investment in the Fund may have other tax implications. Please consult your tax advisor about federal, state, local, foreign or other tax laws applicable to you. Investors, including non-U.S. investors, may wish to consult the SAI tax section for additional disclosure. The Fund seeks to achieve its investment objective by investing in a combination of Underlying Funds each of which intends to qualify and be treated as a regulated investment company for U.S. federal income tax purposes such that substantially all of the Fund's income will result from distributions from such Underlying Funds. Therefore, as applicable, and except as otherwise stated, references in this section to the assets owned or income earned by the Fund will include such assets and income of the corresponding Underlying Funds.

The Fund intends to elect to be treated as a regulated investment company and intends each year to qualify and to be eligible to be treated as such. A regulated investment company generally is not subject to tax at the corporate level on income and gains that are timely distributed to shareholders. In order to qualify and be eligible for treatment as a regulated investment company, the Fund must, among other things, satisfy diversification, 90% gross income and distribution requirements. The Fund's failure to qualify as a regulated investment company would result in corporate level taxation, and consequently, a reduction in income available for distribution to shareholders.

For U.S. federal income tax purposes, distributions of investment income generally are taxable to you as ordinary income. Taxes on distributions of capital gains generally are determined by how long the applicable Fund owned (or is deemed to have owned) the investments that generated them, rather than how long you have owned your Fund Shares. Distributions of net capital gains (that is, the excess of net long-term capital gains over net short-term capital losses) from the sale of investments that the Fund owned (or is deemed to have owned) for more than one year that are properly reported by the Fund as capital gain dividends generally will be treated as long-term capital gain includible in your net capital gain and taxed to individuals at reduced rates. Distributions of gains from investments that the Fund owned (or is deemed to have owned) for one year or less generally will be taxable to you as ordinary income. Distributions of investment income properly reported by the Fund as derived from “qualified dividend income,” which will not include income from the Fund's portfolio securities on loan, are taxed to individuals at the rates applicable to net capital gain, provided holding period and other requirements are met by both the shareholder and the Fund. Distributions are taxable to you even if they are paid from income or gains earned by the Fund before your investment (and thus were included in the price you paid for

your shares). Distributions may also be subject to state and local taxes and are taxable whether you receive them in cash or reinvest them in additional shares. Distributions in excess of the Fund's current and accumulated earnings and profits are treated as a return of capital to the extent of your basis in the applicable Fund's shares, and, in general, as capital gain thereafter.

Any gain resulting from the redemption or other taxable disposition of Fund Shares generally will also be taxable to you as either short-term or long-term capital gain, depending upon how long you held such Fund Shares.

An additional 3.8% Medicare contribution tax is imposed on the “net investment income” of individuals, estates and trusts to the extent their income exceeds certain threshold amounts. Net investment income generally includes for this purpose dividends paid by the Fund, including any capital gain dividends, and net gains recognized on the redemption (or other taxable disposition) of Fund Shares.

The Fund's income from or proceeds of dispositions of its investments in non-U.S. assets may be subject to non-U.S. withholding or other taxes, which will reduce the yield on those investments. In certain instances, the Fund may be entitled to elect to pass through to its shareholders a credit (or deduction, for a shareholder that itemizes deductions and so chooses) for foreign taxes (if any) borne with respect to foreign securities income earned by the Fund. If the Fund so elects, shareholders will include in gross income from foreign sources their pro rata shares of such taxes, if any, treated as paid by the Fund. There can be no assurance that the Fund will make such election, even if it is eligible to do so. If the Fund does not qualify for or does not make such election, shareholders will not be entitled separately to claim a credit or deduction with respect to foreign taxes incurred by the Fund; in that case the foreign tax will nonetheless reduce the Fund's taxable income. Shareholders that are not subject to U.S. federal income tax, and those who invest in the Fund through tax-advantaged accounts (including those who invest through IRAs or other tax-advantaged retirement plans), generally will receive no benefit from any tax credit or deduction passed through by the Fund. Under certain circumstances, if the Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Fund Shares could be affected or any foreign tax credits or deductions passed through to shareholders in respect of the Fund's foreign taxes for the current year could be reduced.

Certain of the Fund's investment practices, including derivative transactions and investments in debt obligations issued or purchased at a discount, will be subject to special and complex U.S. federal income tax provisions. These special rules may affect the timing, character, and/or amount of the Fund's distributions, and may require the Fund to sell its investments at a time when it is not advantageous to do so.

The Fund's investments in the Underlying Funds may cause the tax treatment of the Fund's gains, losses and distributions to differ from the tax treatment that would apply if the Fund invested directly in the types of securities held by the Underlying Funds. As a result, investors may receive taxable distributions earlier and recognize higher amounts of capital gain or ordinary income than they otherwise would.

If you are not a U.S. person, dividends paid by the Fund that the Fund properly reports as capital gain dividends, short-term capital gain dividends, or interest-related dividends, each as further defined in the SAI, are not subject to withholding of U.S. federal income tax, provided that certain requirements are met. The Fund is permitted, but is not required, to report any part of its dividends as are eligible for such treatment. The Fund's dividends other than those the Fund so reports as capital gain dividends, short-term capital gain dividends, or interest-related dividends generally will be subject to U.S. withholding tax at a 30% rate (or lower applicable treaty rate). See the Fund's SAI for further information.

The U.S. Treasury and Internal Revenue Service (the “IRS”) generally require the Fund to obtain information sufficient to identify the status of each shareholder under sections 1471-1474 of the Code, and the U.S. Treasury and IRS guidance issued thereunder (collectively, “FATCA”) or under an applicable intergovernmental agreement between the United States and a foreign government. Please see the SAI for more information on FATCA reporting requirements.

Cost Basis Reporting. U.S. Treasury regulations mandate cost basis reporting to shareholders and the IRS for redemptions of Fund Shares acquired on or after January 1, 2012 (“Post Effective Date Shares”). If you acquire and hold shares directly through the Fund and not through a Financial Intermediary, SS&C GIDS, Inc. will use a default average cost basis methodology for tracking and reporting your cost basis on Post Effective Date Shares, unless you request, in writing, another cost basis reporting methodology.

Financial Intermediary Arrangements

Payments to Financial Intermediaries

The Fund has adopted a distribution plan pursuant to Rule 12b-1 under the 1940 Act under which the Fund may compensate SSGA FD (or others) for services in connection with the distribution of the Fund's Class R3 shares and for services provided to shareholders in that class (the “Plan”). The Plan calls for payments at an annual rate (based on average daily net assets) of 0.25% of the Fund's net assets attributable to its Class R3 shares. Because these fees are paid out of the assets of the Fund attributable to its Class R3 shares on an ongoing basis, they will increase the cost of your investment and may cost you more over time than paying other types of sales charges.

The Fund may pay distribution fees and other amounts described in this Prospectus at a time when shares of that Fund are unavailable for purchase.

Other Payments to Financial Intermediaries

In addition to payments under the Plan described above, the Fund may reimburse SSGA FD or its affiliates for payments made to Financial Intermediaries that provide certain administrative, recordkeeping, and account maintenance services. The amount of the reimbursement and the manner in which it is calculated are reviewed by the Trustees periodically.

Financial Intermediaries are firms that sell shares of mutual funds, including the Fund, and/or provide certain administrative and account maintenance services to mutual fund investors. Financial Intermediaries may include, among others, brokers, financial planners or advisers, banks, retirement plan recordkeepers and insurance companies.

In some cases, a Financial Intermediary may hold its clients' Fund Shares in nominee or street name and may utilize omnibus accounts. Shareholder services provided by a Financial Intermediary may (though they will not necessarily) include, among other things: establishing and maintaining shareholder account registrations; receiving and processing purchase and redemption orders, including aggregated orders and delivering orders to the Fund's transfer agent; processing and mailing trade confirmations, periodic statements, prospectuses, annual reports, semiannual reports, shareholder notices, and other SEC-required communications; capturing and processing tax data; issuing and mailing dividend checks to shareholders who have selected cash distributions; preparing record date shareholder lists for proxy solicitations; and collecting and posting distributions to shareholder accounts.

The Financial Intermediary is often compensated by SSGA FD or its affiliates for the services it performs and in such cases is typically paid continually over time, during the period when the Financial Intermediary's clients hold investments in the Fund. The amount of continuing compensation paid by SSGA FD or its affiliates to different Financial Intermediaries for distribution and/or shareholder services varies. Any compensation is typically a percentage of the value of the Financial Intermediary's clients' investments in the Fund or a per account fee. The variation in compensation may, but will not necessarily, reflect enhanced or additional services provided by the Financial Intermediary.

If you invest through a Financial Intermediary and meet the eligibility criteria for more than one share class, you should discuss with your Financial Intermediary which share class is appropriate for you. Your financial adviser and the Financial Intermediary employing him or her may have an incentive to recommend one share class over another, when you are eligible to invest in more than one share class. Please speak with your financial adviser to learn more about the total amounts paid to your financial adviser and his or her firm by the Fund or its affiliates with respect to the different share classes offered by the Fund.

SSGA FD and its affiliates (including SSGA FM), at their own expense and out of their own assets, may also provide other compensation to Financial Intermediaries in connection with sales of the Fund's shares or the servicing of shareholders or shareholder accounts. Such compensation may include, but is not limited to, financial assistance to Financial Intermediaries in connection with conferences, sales, or training programs for their employees; seminars for the public; advertising or sales campaigns; or other Financial Intermediary-sponsored special events. In some instances, this compensation may be made available only to certain Financial Intermediaries whose representatives have sold or are expected to sell significant amounts of shares. Dealers may not use sales of the Fund's shares to qualify for this compensation to the extent prohibited by the laws or rules of any state or any self-regulatory agency, such as Financial Industry Regulatory Authority, Inc.

If payments to Financial Intermediaries by the distributor or adviser for a particular mutual fund complex exceed payments by other mutual fund complexes, your financial adviser and the Financial Intermediary employing him or her may have an incentive to recommend that fund complex over others. Please speak with your financial adviser to learn more about the total amounts paid to your financial adviser and his or her firm by SSGA FD and its affiliates and by sponsors of other mutual funds he or she may recommend to you. You should also consult disclosures made by your Financial Intermediary at the time of purchase.

Third-Party Transactions. The State Street Funds have authorized certain Financial Intermediaries to accept purchase, redemption and exchange orders on the State Street Funds' behalf. Orders received for a State Street Fund by a Financial Intermediary that has been authorized to accept orders on the Fund's behalf (or other Financial Intermediaries designated by the Financial Intermediary) will be deemed accepted by the Fund at the time they are received by the Financial Intermediary and will be priced based on the Fund's next NAV determination as long as the Financial Intermediary transmits the order in good form and in a timely manner to the applicable State Street Fund(s). The State Street Funds will be the sole party to determine if a trade is received in good order. The Financial Intermediary is responsible for transmitting your orders and associated funds in good form and in a timely manner to the applicable State Street Fund(s). The State Street Funds will not be responsible for delays by the Financial Intermediary in transmitting your orders, including timely transfer of payment, to the Fund.

If you are purchasing, selling, exchanging or holding State Street Fund shares through a program of services offered by a Financial Intermediary, you may be required by the Financial Intermediary to pay additional fees. You should contact the Financial Intermediary for information concerning what additional fees, if any, may be charged.

Appendix A – Underlying Funds

The following is a brief description of the investment objective and principal investment policies of certain of the Underlying Funds in which the Fund may invest. The Fund invests in the Underlying Funds in varying proportions.

You'll find more detailed information about each of these Underlying Fund's investment strategies and risks in its prospectus and SAI. Refer to www.ssga.com or contact your financial advisor for details.

State Street Equity 500 Index II Portfolio

The State Street Equity 500 Index II Portfolio seeks to provide investment results that, before expenses, correspond generally to the total return of the S&P 500® Index. The Portfolio is not managed according to traditional methods of “active” investment management, which involve the buying and selling of securities based upon economic, financial and market analysis and investment judgment. Instead, the Portfolio, using a “passive” or “indexing” investment approach, seeks to provide investment results that, before expenses, correspond generally to the total return of the S&P 500. The Portfolio generally intends to invest in all stocks comprising the S&P 500 in approximate proportion to their weightings in the Index. However, under various circumstances, it may not be possible or practicable to purchase all stocks in those weightings. In those circumstances, the Portfolio may purchase a sample of the stocks in the Index in proportions expected by the Portfolio's investment adviser, SSGA FM, to match generally the performance of the Index as a whole. In addition, from time to time stocks are added to or removed from the Index. The Portfolio may sell securities that are represented in the Index, or purchase securities that are not yet represented in the Index, in anticipation of their removal from or addition to the Index. Under normal circumstances, the Portfolio generally invests substantially all, but at least 80%, of its net assets (plus borrowings, if any) in securities comprising the Index or in securities that the Adviser determines have economic characteristics that are comparable to the economic characteristics of securities that comprise the Index. The notional value of the Portfolio's investments in derivatives or other synthetic instruments that provide exposures comparable, in the judgment of the Adviser, to investments in the Index may be counted toward satisfaction of this 80% policy. In addition, the Portfolio may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser).

The Portfolio may at times purchase or sell futures contracts, or options on those futures, in lieu of investing directly in the stocks making up the Index. The Portfolio might do so, for example, in order to increase its investment exposure pending investment of cash in the stocks comprising the Index. Alternatively, the Portfolio might use futures or options on futures to reduce its investment exposure in situations where it intends to sell a portion of the stocks in its portfolio but the sale has not yet been completed.

The Portfolio may also enter into other derivatives transactions, including the use of options or swap transactions, in lieu of investing directly in the stocks making up the Index. The Portfolio may also, to the extent permitted by applicable law, invest in shares of other mutual funds whose investment objectives and policies are similar to those of the Portfolio (including funds advised by the Adviser).

State Street Small/Mid Cap Equity Index Portfolio

The State Street Small/Mid Cap Equity Index Portfolio seeks to provide investment results that, before expenses, correspond generally to the total return of an index that tracks the performance of mid-to small- capitalization exchange traded U.S. equity securities. The Portfolio is not managed according to traditional methods of “active” investment management, which involve the buying and selling of securities based upon economic, financial and market analysis and investment judgment. Instead, the Portfolio, using a “passive” or “indexing” investment approach, seeks to provide investment results that, before expenses, correspond generally to the total return of the Russell Small Cap Completeness Index. The Portfolio generally intends to invest in all stocks comprising the Russell Small Cap Completeness Index in approximate proportion to their weightings in the Russell Small Cap Completeness Index. However, under various circumstances, it may not be possible or practicable to purchase all stocks in those weightings. In those circumstances, the Portfolio may purchase a sample of the stocks in the Russell Small Cap Completeness Index in proportions expected by SSGA FM, the investment adviser to the Portfolio, to match generally the performance of the Russell Small Cap Completeness Index as a whole. In addition, from time to time stocks are added to or removed from the Russell Small Cap Completeness Index. The Portfolio may sell securities that are represented in the Russell Small Cap Completeness Index, or purchase securities that are not yet represented in the Russell Small Cap Completeness Index, in anticipation of their removal from or addition to the Russell Small Cap Completeness Index. Under normal market conditions, the Portfolio invests at

least 80% of its net assets (plus borrowings, if any) in stocks in the Russell Small Cap Completeness Index. The notional value of the Portfolio's investments in derivatives or other synthetic instruments that provide exposures comparable, in the judgment of the Adviser, to investments in the Russell Small Cap Completeness Index may be counted toward satisfaction of this 80% policy. In addition, the Portfolio may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser). The Portfolio may purchase or sell futures contracts on the Index, or options on those futures, in lieu of investing directly in the stocks making up the Index.

The Portfolio may also enter into other derivatives transactions, including the use of options or swap transactions relating to the Index or any securities comprising the Index, in lieu of investing directly in the stocks making up the Index. The Portfolio may, to the extent permitted by applicable law, invest in shares of other mutual funds whose investment objectives and policies are similar to those of the Portfolio (including funds advised by the Adviser).

The State Street Global All Cap Equity ex-U.S. Index Portfolio (the “Portfolio”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of a broad-based index of world (ex-U.S.) equity markets over the long term. The Portfolio is an “index” fund that seeks to track, before fees and expenses, the total return performance of the MSCI ACWI ex USA Investable Market Index (the “MSCI ACWI ex USA IMI Index” or sometimes referred to in context as the “Index”) over the long term. As an “index” fund, the Portfolio is not managed according to traditional methods of “active” investment management, which involve the buying and selling of securities based upon economic, financial and market analysis and investment judgment. In seeking to track the performance of the Index, the Portfolio employs a sampling strategy, which means that the Portfolio is not required to purchase all of the securities represented in the Index. Instead, the Portfolio may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The number of holdings in the Portfolio will be based on a number of factors, including asset size of the Portfolio. The Adviser generally expects the Portfolio to hold fewer than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Portfolio's investment objective. Under normal circumstances, the Portfolio generally invests substantially all, but at least 80%, of its net assets (plus borrowings, if any) in securities comprising the Index or in American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”) providing exposure to securities comprising the Index. The notional value of the Portfolio's investments in derivatives or other synthetic instruments that provide exposures comparable, in the judgment of the Adviser, to investments in the Index may be counted toward satisfaction of this 80% policy. In addition, the Portfolio may invest in equity securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser). The Portfolio may also purchase or sell futures contracts, or options on those futures, in lieu of investing directly in the stocks making up the Index. The Portfolio might do so, for example, in order to increase its investment exposure pending investment of cash in stocks or other investments. Alternatively, the Portfolio might use futures or options on futures to reduce its investment exposure in situations where it intends to sell a portion of the stocks in its portfolio but the sale has not yet been completed. The Portfolio may also enter into other derivatives transactions, including the use of options, forwards or swap transactions, in lieu of investing directly in the stocks making up the Index. The Portfolio may also, to the extent permitted by applicable law, invest in shares of other mutual funds whose investment objectives and policies are similar to those of the Portfolio (including funds advised by the Adviser).

The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund.

mined by the Adviser to be in the best interest of the Fund in pursuing its objective. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index and in depositary receipts ADRs or GDRs based on securities comprising the Index.

Description of the Fund and its Investments and Risks

The Fund's Prospectus contains information about the investment objective and policies of the Fund. This SAI should only be read in conjunction with the Prospectus of the Fund.

In addition to the principal investment strategies and the principal risks of the Fund described in the Fund's Prospectus, the Fund may employ other investment practices and may be subject to additional risks, which are described below.

The Target Retirement 2070 Fund seeks to achieve its investment objective by investing in a combination of domestic and international mutual funds and exchange-traded funds sponsored by SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) or its affiliates (“Underlying Funds”) using an asset allocation strategy. In managing their portfolios of investments, the Underlying Funds may purchase various securities and investment related instruments and make use of various investment techniques, including, but not limited to, those described below. Except as otherwise stated, references in this section to “the Funds,” “each Fund,” or “a Fund” may, as applicable, refer to the Funds, one or more Underlying Funds, or more than one of the foregoing.

Additional Investments and Risks

To the extent consistent with its investment objective and restrictions, the Fund may invest in the following instruments and use the following techniques, and is subject to the following additional risks.

Bonds

The Fund may invest a portion of their assets in bonds. A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond's face value) periodically or on a specified maturity date; provided, however, a zero-coupon bond pays no interest to its holder during its life. The value of a zero-coupon bond to the Fund consists of the difference between such bond's face value at the time of maturity and the price for which it was acquired, which may be an amount significantly less than its face value (sometimes referred to as a “deep discount” price).

An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond's yield (income as a percent of the bond's current value) may differ from its coupon rate as its value rises or falls. Fixed rate bonds generally are also subject to inflation risk, which is the risk that the value of the bond or income from the bond will be worth less in the future as inflation decreases the value of money. This could mean that, as inflation increases, the “real” value of the assets of the Fund holding fixed rate bonds can decline, as can the value of the Fund's distributions. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. The Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation's earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer's general creditworthiness) or secured (also backed by specified collateral). The investment return of corporate bonds reflects interest on the bond and changes in the market value of the bond. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by such a security.

Cash Reserves

The Fund may hold portions of its assets in cash or short-term debt instruments with remaining maturities of 397 days or less pending investment or to meet anticipated redemptions and day-to-day operating expenses. Short-term debt instruments consist of: (i) short-term obligations of the U.S. Government, its agencies, instrumentalities, authorities or political subdivisions; (ii) other short-term debt securities rated at the time of purchase Aa or higher by Moody's Investors Service, Inc. (“Moody's”) or AA or higher by S&P or, if unrated, of comparable quality in the opinion of SSGA FM; (iii) commercial paper; (iv) bank obligations, including negotiable certificates of deposit, time deposits and bankers' acceptances; and (v) repurchase agreements.

Cleared Derivatives Transactions

Transactions in some types of swaps are required to be centrally cleared by applicable rules and regulations and the Fund may also voluntarily centrally clear other transactions that are available for clearing. In a cleared derivatives transaction, the Fund's counterparty to the transaction is a central derivatives clearing organization, or clearing house, rather than a bank or broker. Because the Fund is not a member of a clearing house, and only members of a clearing house can

participate directly in the clearing house, the Fund holds cleared derivatives through accounts at clearing members. In cleared derivatives transactions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Clearing members guarantee performance of their clients' obligations to the clearing house. Centrally cleared derivatives arrangements may be less favorable to the Fund than bilateral (non-cleared) arrangements. For example, the Fund may be required to provide greater amounts of margin for cleared derivatives transactions than for bilateral derivatives transactions. Also, in contrast to bilateral derivatives transactions, in some cases following a period of notice to the Fund, a clearing member generally can require termination of existing cleared derivatives transactions at any time or an increase in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions or to terminate transactions at any time. The Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or which the Adviser expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund's behalf. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of the transaction, including loss of an increase in the value of the transaction and loss of hedging protection. In addition, the documentation governing the relationship between the Fund and clearing members is drafted by the clearing members and generally is less favorable to the Fund than typical bilateral derivatives documentation. For example, documentation relating to cleared derivatives generally includes a one-way indemnity by the Fund in favor of the clearing member for losses the clearing member incurs as the Fund's clearing member. Also, such documentation typically does not provide the Fund any remedies if the clearing member defaults or becomes insolvent.

Counterparty risk with respect to derivatives has been and will continue to be affected by rules and regulations relating to the derivatives market. With respect to a centrally cleared transaction, a party is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position. Credit risk of market participants with respect to centrally cleared derivatives is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted and what impact an insolvency of a clearing house would have on the financial system. A clearing member is obligated by contract and regulation to segregate all funds received from customers with respect to cleared derivatives positions from the clearing member's proprietary assets. However, all funds and other property received by a clearing member from its customers with respect to cleared derivatives are generally held by the clearing member on a commingled basis in an omnibus account (which can be invested in instruments permitted under the regulations). Therefore, the Fund might not be fully protected in the event of the bankruptcy of the Fund's clearing member because the Fund would be limited to recovering only a pro rata share of the funds held by the clearing member on behalf of customers, with a claim against the clearing member for any deficiency. Also, the clearing member is required to transfer to the clearing house the amount of margin required by the clearing house for cleared derivatives, which amount is generally held in an omnibus account at the clearing house for all customers of the clearing member. Regulations promulgated by the Commodity Futures Trading Commission (the “CFTC”) require that the clearing member notify the clearing house of the initial margin provided by the clearing member to the clearing house that is attributable to each customer. However, if the clearing member does not accurately report the Fund's initial margin, the Fund is subject to the risk that a clearing house will use the assets attributable to it in the clearing house's omnibus account to satisfy payment obligations a defaulting customer of the clearing member has to the clearing house. In addition, clearing members generally provide the clearing house the net amount of variation margin required for cleared swaps for all of its customers, rather than individually for each customer. The Fund is therefore subject to the risk that a clearing house will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default, and the risk that the Fund will be required to provide additional variation margin to the clearing house before the clearing house will move the Fund's cleared derivatives positions to another clearing member. In addition, if a clearing member does not comply with the applicable regulations or its agreement with the Fund, or in the event of fraud or misappropriation of customer assets by a clearing member, the Fund could have only an unsecured creditor claim in an insolvency of the clearing member with respect to the margin held by the clearing member.

Russia Sanctions Risk

Following Russia's invasion of Ukraine in late February 2022, various countries, including the U.S. and the U.K., as well as the E.U., issued broad-ranging economic sanctions against Russia. The U.S. and other countries have also imposed economic sanctions on Belarus and may impose sanctions on other countries that support Russia's invasion. A large number of corporations and U.S. states have also announced plans to divest interests or otherwise curtail business dealings with certain Russian businesses. These sanctions and any additional sanctions or other intergovernmental actions that have been or may be undertaken in the future, against Russia, Russian entities or Russian individuals, or other countries that support Russia's military invasion, may result in the devaluation of Russian currency, a downgrade in

the country's credit rating, an immediate freeze of Russian assets, a decline in the value and liquidity of Russian securities, property or interests, and/or other adverse consequences to the Russian economy or the Fund. The scope and scale of sanctions in place at a particular time may be expanded or otherwise modified in a way that have negative effects on the Fund. Sanctions, or the threat of new or modified sanctions, could impair the ability of the Fund to buy, sell, hold, receive, deliver or otherwise transact in certain affected securities or other investment instruments. Sanctions could also result in Russia taking counter measures or other actions in response (including cyberattacks and espionage), which may further impair the value and liquidity of Russian securities. These sanctions, and the resulting disruption of the Russian economy, may cause volatility in other regional and global markets and may negatively impact the performance of various sectors and industries, as well as companies in other countries, which could have a negative effect on the performance of the Fund, even if the Fund does not have direct exposure to securities of Russian issuers. As a collective result of the imposition of sanctions, Russian government countermeasures and the impact that they have had on the trading markets for Russian securities, certain Funds have used, and may in the future use, fair valuation procedures approved by the Fund's Board to value certain Russian securities, which could result in such securities being deemed to have a zero value.

Swap Execution Facilities

Certain derivatives contracts are required to be executed through swap execution facilities (“SEFs”). A SEF is a trading platform where multiple market participants can execute derivatives by accepting bids and offers made by multiple other participants in the platform. Such requirements may make it more difficult and costly for investment funds, such as the Fund, to enter into highly tailored or customized transactions. Trading swaps on a SEF may offer certain advantages over traditional bilateral over-the-counter trading, such as ease of execution, price transparency, increased liquidity and/or favorable pricing. Execution through a SEF is not, however, without additional costs and risks, as parties are required to comply with SEF and CFTC rules and regulations, including disclosure and recordkeeping obligations, and SEF rights of inspection, among others. SEFs typically charge fees, and if the Fund executes derivatives on a SEF through a broker intermediary, the intermediary may impose fees as well. The Fund also may be required to indemnify a SEF, or a broker intermediary who executes swaps on a SEF on the Fund's behalf, against any losses or costs that may be incurred as a result of the Fund's transactions on the SEF. In addition, the Fund may be subject to execution risk if it enters into a derivatives transaction that is required to be cleared, and no clearing member is willing to clear the transaction on the Fund's behalf. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of any increase in the value of the transaction after the time of the trade.

Risks Associated with Derivatives Regulation

The U.S. government has enacted and is continuing to implement legislation that provides for regulation of the derivatives market, including clearing, margin, reporting, and registration requirements. The European Union (“E.U.”), the United Kingdom (the “U.K.”) and some other countries have also adopted and are continuing to implement similar requirements, which will affect the Fund when it enters into a derivatives transaction with a counterparty organized in that country or otherwise subject to that country's derivatives regulations. Such rules and other new rules and regulations could, among other things, restrict the Fund's ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. While the rules and regulations and central clearing of some derivatives transactions are designed to reduce systemic risk (i.e., the risk that the interdependence of large derivatives dealers could cause them to suffer liquidity, solvency or other challenges simultaneously), there is no assurance that they will achieve that result, and in the meantime, as noted above, central clearing and related requirements expose the Fund to new kinds of costs and risks.

For example, in the event of a counterparty's (or its affiliate's) insolvency, the Fund's ability to exercise remedies, such as the termination of transactions, netting of obligations and realization on collateral, could be stayed or eliminated under special resolution regimes adopted in the United States, the E.U., the U.K. and various other jurisdictions. Such regimes provide government authorities with broad authority to intervene when a financial institution is experiencing financial difficulty. In particular, with respect to counterparties who are subject to such proceedings in the E.U. and the U.K. the liabilities of such counterparties to the Fund could be reduced, eliminated, or converted to equity in such counterparties (sometimes referred to as a “bail in”).

The Securities and Exchange Commission (“SEC”) adopted Rule 18f-4 under the 1940 Act providing for the regulation of registered investment companies' use of derivatives and certain related instruments. The rule, among other things, limits derivatives exposure through one of two value-at-risk tests and eliminates the asset segregation framework for covering derivatives and certain financial instruments arising from the SEC's Release 10666 and ensuing staff guidance. The rule

also requires funds to adopt and implement a derivatives risk management program (including the appointment of a derivatives risk manager and the implementation of certain testing requirements) and subjects funds to certain reporting requirements in respect of derivatives. Limited derivatives users (as determined by Rule 18f-4) are not, however, subject to the full requirements under the rule.

Additionally, U.S. regulators, the E.U., the U.K. and certain other jurisdictions have adopted minimum margin and capital requirements for uncleared derivatives transactions. These rules impose minimum margin requirements on derivatives transactions between the Fund and its counterparties and may increase the amount of margin the Fund is required to provide. They impose regulatory requirements on the timing of transferring margin and the types of collateral that parties are permitted to exchange.

Since 2021, the SEC has proposed and, in some cases, finalized several new rules regarding a wide range of topics related to the Fund. For example, the SEC has proposed new rules requiring the reporting and public disclosure of a manager's positions in security-based swaps, including CDS, equity total return swaps and related positions. The SEC has also finalized new rules restricting activities that could be considered to be manipulative in connection with security-based swaps, new rules requiring managers to file monthly confidential reports with the SEC regarding equity short sales and related activity, new rules regarding regulatory and public reporting of certain securities lending transactions, and new rules requiring the central clearing of certain cash and repurchase transactions involving U.S. Treasuries. These and other proposed new rules, whether assessed on an individual or collective basis, could fundamentally change the current regulatory framework for relevant markets and market participants, including having a material impact on activities of investment managers and their funds. While it is currently difficult to predict the full impact of these new rules, these rules could make it more difficult for the Fund to execute certain investment strategies and may have an adverse effect on the Fund's ability to generate returns.

These and other regulations are relatively new and evolving, so their full impact on the Fund and the financial system are not yet known.

Commodities

General. The Fund may invest in commodities. There are several additional risks associated with transactions in commodity futures contracts, swaps on commodity futures contracts, commodity forward contracts and other commodities instruments. In the commodity instruments markets, producers of the underlying commodity may decide to hedge the price risk of selling the commodity by selling commodity instruments today to lock in the price of the commodity at delivery tomorrow. In order to induce speculators to purchase the other side of the same commodity instrument, the commodity producer generally must sell the commodity instrument at a lower price than the expected future spot price. Conversely, if most hedgers in the commodity instruments market are purchasing commodity instruments to hedge against a rise in prices, then speculators will only sell the other side of the commodity instrument at a higher future price than the expected future spot price of the commodity. The changing nature of the hedgers and speculators in the commodity markets will influence whether futures prices are above or below the expected future spot price, which can have significant implications for the Fund. If the nature of hedgers and speculators in commodity instruments markets has shifted when it is time for the Fund to reinvest the proceeds of a maturing contract in a new commodity instrument, the Fund might reinvest at a higher or lower future price, or choose to pursue other investments. The commodities which underlie commodity instruments may be subject to additional economic and non-economic variables, such as drought, floods, weather, livestock disease, embargoes, tariffs, war and international economic, political and regulatory developments. These factors may have a larger impact on commodity prices and commodity-linked instruments than on traditional securities. Certain commodities are also subject to limited pricing flexibility because of supply and demand factors. Others are subject to broad price fluctuations as a result of the volatility of the prices for certain raw materials and the instability of supplies of other materials. These additional variables may create additional investment risks. which subject the Fund's investments to greater volatility than other investments. Also, unlike the financial instruments markets, in the commodity instruments markets there are costs of physical storage associated with purchasing the underlying commodity. The price of the commodity instruments contract will reflect the storage costs of purchasing the physical commodity, including the time value of money invested in the physical commodity. To the extent that the storage costs for an underlying commodity change while the Fund is invested in instruments on that commodity, the value of the commodity instrument may change proportionately.

Commodity-Linked Investments. The Fund may invest in commodity-linked investments. The Fund may seek to provide exposure to the investment returns of real assets that trade in the commodity markets through commodity-linked derivatives securities, such as structured notes, discussed below, which are designed to provide this exposure without direct investment in physical commodities or commodities futures contracts. Real assets are assets such as oil, gas,

industrial and precious metals, livestock, and agricultural or meat products, or other items that have tangible properties, as compared to stocks or bonds, which are financial instruments. In choosing investments, the Adviser seeks to provide exposure to various commodities and commodity sectors. The value of commodity-linked derivatives securities held by the Fund may be affected by a variety of factors, including, but not limited to, overall market movements and other factors affecting the value of particular industries or commodities, such as weather, disease, embargoes, acts of war or terrorism, or political and regulatory developments.

The prices of commodity-linked derivatives securities may move in different directions than investments in traditional equity and debt securities when the value of those traditional securities is declining due to adverse economic conditions. As an example, during periods of rising inflation, debt securities have historically tended to decline in value due to the general increase in prevailing interest rates. Conversely, during those same periods of rising inflation, the prices of certain commodities, such as oil and metals, have historically tended to increase. Of course, there cannot be any guarantee that these investments will perform in that manner in the future, and at certain times the price movements of commodity-linked instruments have been parallel to those of debt and equity securities. Commodities have historically tended to increase and decrease in value during different parts of the business cycle than financial assets. Nevertheless, at various times, commodities prices may move in tandem with the prices of financial assets and thus may not provide overall portfolio diversification benefits. Under favorable economic conditions, the Fund's investments may be expected to underperform an investment in traditional securities. Over the long term, the returns on the Fund's investments are expected to exhibit low or negative correlation with stocks and bonds.

Because commodity-linked investments are available from a relatively small number of issuers, the Fund's investments will be particularly subject to counterparty risk, which is the risk that the issuer of the commodity-linked derivatives (which issuer may also serve as counterparty to a substantial number of the Fund's commodity-linked and other derivatives investments) will not fulfill its contractual obligations.

The Fund's ability to invest in commodity-linked investments may be limited by the Fund's intention to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986 (the “Code”) and could bear on the ability of the Fund to so qualify. See “Taxation of the Fund” below.

Credit Default Swaps and Total Return Swaps

The Fund may enter into credit default swaps or total return swaps to gain market exposure, manage liquidity, increase total returns or for hedging purposes. Credit default swaps and total return swaps are typically governed by the standard terms and conditions of an ISDA Master Agreement.

A credit default swap involves a protection buyer and a protection seller. The Fund may be either a protection buyer or seller. The protection buyer in a credit default swap makes periodic premium payments to the protection seller during the swap term in exchange for the protection seller agreeing to make certain defined payments to the protection buyer in the event certain defined credit events occur with respect to a particular security, issuer or basket of securities. A total return swap involves a total return receiver and a total return payor. The Fund may either be a total return receiver or payor. Generally, the total return payor sells to the total return receiver an amount equal to all cash flows and price appreciation on a defined security or asset payable at periodic times during the swap term (i.e., credit risk) in return for a periodic payment from the total return receiver based on a designated interest rate and spread plus the amount of any price depreciation on the reference security or asset. The total return payor does not need to own the underlying security or asset to enter into a total return swap. The final payment at the end of the swap term includes final settlement of the current market price of the underlying reference security or asset, and payment by the applicable party for any appreciation or depreciation in value. Usually, collateral must be posted by the total return receiver to secure the periodic interest-based and market price depreciation payments depending on the credit quality of the underlying reference security and creditworthiness of the total return receiver, and the collateral amount is marked-to-market daily equal to the market price of the underlying reference security or asset between periodic payment dates.

In both credit default swaps and total return swaps, the same general risks inherent to derivatives transactions are present; however, the use of credit default swaps and total return swaps can involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps and total return swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk. The Fund will enter into credit default swap or a total return swap only with counterparties that the Adviser determines to meet certain standards of creditworthiness. In a credit default swap, a buyer generally also will lose its premium and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable

obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. The Fund's obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund).

Swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with the ownership of stocks, bonds, and other traditional investments. The use of a swap agreement requires an understanding not only of the referenced obligation, reference rate, or index, but also of the swap agreement itself. Because some swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain swaps have the potential for unlimited loss, regardless of the size of the initial investment.

Custodial Risk

There are risks involved in dealing with the custodians or brokers who hold the Fund's investments or settle the Fund's trades. It is possible that, in the event of the insolvency or bankruptcy of a custodian or broker, the Fund would be delayed or prevented from recovering its assets from the custodian or broker, or its estate, and may have only a general unsecured claim against the custodian or broker for those assets. In recent insolvencies of brokers or other financial institutions, the ability of certain customers to recover their assets from the insolvent's estate has been delayed, limited, or prevented, often unpredictably, and there is no assurance that any assets held by the Fund with a custodian or broker will be readily recoverable by the Fund. In addition, there may be limited recourse against non-U.S. sub-custodians in those situations in which the Fund invests in markets where custodial and/or settlement systems and regulations are not fully developed, including emerging markets, and the assets of the Fund have been entrusted to such sub-custodians. SSGA FM or an affiliate may serve as the custodian of the Fund.

Eurodollar Certificates of Deposit (“ECDs”), Eurodollar Time Deposits (“ETDs”) and Yankee Certificates of Deposit (“YCDs”)

The Fund may invest in ECDs, ETDs and YCDs. ECDs and ETDs are U.S. dollar denominated certificates of deposit and time deposits, respectively, issued by non-U.S. branches of domestic banks and non-U.S. banks. YCDs are U.S. dollar denominated certificates of deposit issued by U.S. branches of non-U.S. banks.

Different risks than those associated with the obligations of domestic banks may exist for ECDs, ETDs and YCDs because the banks issuing these instruments, or their domestic or non-U.S. branches, are not necessarily subject to the same regulatory requirements that apply to domestic banks, such as loan limitations, examinations and reserve, accounting, auditing, recordkeeping and public reporting requirements. Obligations of non-U.S. issuers also involve risks such as future unfavorable political and economic developments, withholding or other taxes, seizures of non-U.S. deposits, currency controls, interest limitations, and other governmental restrictions that might affect repayment of principal or payment of interest, or the ability to honor a credit commitment.

Foreign Currency Transactions and Foreign Currency Derivatives

The Fund may enter into a variety of different foreign currency transactions, including, by way of example, currency forward transactions, spot transactions, futures and forward contracts, swaps, or options. Most of these transactions are entered into “over the counter,” and the Fund assumes the risk that the counterparty may be unable or unwilling to perform its obligations, in addition to the risk of unfavorable or unanticipated changes in the values of the currencies underlying the transactions. Certain types of over-the-counter currency transactions may be uncollateralized, and the Fund may not be able to recover all or any of the assets owed to it under such transactions if its counterparty should default. In some markets or in respect of certain currencies, the Fund may be required, or agree, in SSGA FM's discretion, to enter into foreign currency transactions via the custodian's relevant sub-custodian. SSGA FM may be subject to a conflict of interest in agreeing to any such arrangements on behalf of the Fund. Such transactions executed directly with the sub-custodian are executed at a rate determined solely by such sub-custodian. Accordingly, the Fund may not receive the best pricing of such currency transactions. Regulatory changes in a number of jurisdictions may require that certain currency transactions be subject to central clearing, or be subject to new or increased collateral requirements. These changes could increase the costs of currency transactions to the Fund and may make certain transactions unavailable; they may also increase the credit risk of such transactions to the Fund.

Foreign Securities

The Fund is permitted to invest in foreign securities. Foreign securities include securities of foreign companies and foreign governments (or agencies or subdivisions thereof). If the Fund's securities are held abroad, the countries in which such securities may be held and the sub-custodian holding them must be approved by the Board of Trustees of the Trust (the

“Board of Trustees” or the “Board”) or its delegate under applicable rules adopted by the Securities and Exchange Commission (“SEC”). In buying foreign securities, the Fund may convert U.S. dollars into foreign currency, but only to effect securities transactions on foreign securities exchanges and not to hold such currency as an investment.

The globalization and integration of the world economic system and related financial markets have made it increasingly difficult to define issuers geographically. Accordingly, the Fund intends to construe geographic terms such as “foreign,” “non-U.S.” “European,” “Latin American,” and “Asian,” in the manner that affords to the Fund the greatest flexibility in seeking to achieve its investment objective(s). Specifically, in circumstances where the investment objective and/or strategy is to invest at least some percentage of the Fund's assets in foreign securities, etc., the Fund will take the view that a security meets this description so long as the issuer of a security is tied economically to the particular country or geographic region indicated by words of the relevant investment objective and/or strategy (the “Relevant Language”). For these purposes the issuer of a security is deemed to have that tie if:

The issuer is organized under the laws of the country or a country within the geographic region suggested by the Relevant Language or maintains its principal place of business in that country or region; or

(ii)

The securities are traded principally in the country or region suggested by the Relevant Language; or

(iii)

The issuer, during its most recent fiscal year, derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in the country or region suggested by the Relevant Language or has at least 50% of its assets in that country or region.

In addition, the Fund intend to treat derivatives securities (e.g., call options) by reference to the underlying security. Conversely, if the investment objective and/or strategy of the Fund limits the percentage of assets that may be invested in “foreign securities,” etc. or prohibits such investments altogether, the Fund intend to categorize securities as “foreign,” etc. only if the security possesses all of the attributes described above in clauses (i), (ii) and (iii).

Investments in foreign securities involve special risks and considerations. Foreign companies are not generally subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies and such practices and standards may vary significantly from country to country. There may be less publicly available information about a foreign company than about a domestic company. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited. Foreign markets have different clearance and settlement procedures. Delays in settlement could result in temporary periods when assets of the Fund is uninvested. The inability of the Fund to make intended security purchases due to settlement problems could cause it to miss certain investment opportunities. They may also entail certain other risks, such as the possibility of one or more of the following: imposition of dividend or interest withholding or other taxes (in each case, which taxes could potentially be confiscatory), higher brokerage costs, thinner trading markets, currency blockages or transfer restrictions, expropriation, nationalization, military coups or other adverse political or economic developments; less government supervision and regulation of securities exchanges, brokers and listed companies; and the difficulty of enforcing obligations in other countries. Purchases of foreign securities are usually made in foreign currencies and, as a result, the Fund may incur currency conversion costs and may be affected favorably or unfavorably by changes in the value of foreign currencies against the U.S. dollar. Further, it may be more difficult for the Fund's agents to keep currently informed about corporate actions, which may affect the prices of portfolio securities. Communications between the United States and foreign countries may be less reliable than within the United States, thus increasing the risk of delayed settlements of portfolio transactions or loss of certificates for portfolio securities. Certain markets may require payment for securities before delivery. The Fund's ability and decisions to purchase and sell portfolio securities may be affected by laws or regulations relating to the convertibility of currencies and repatriation of assets.

A number of current significant political, demographic and economic developments may affect investments in foreign securities and in securities of companies with operations overseas. Such developments include dramatic political changes in government and economic policies in several Eastern European countries and the republics composing the former Soviet Union, as well as the unification of the European Economic Community. The course of any one or more of these events and the effect on trade barriers, competition and markets for consumer goods and services are uncertain. Similar

considerations are of concern with respect to developing countries. For example, the possibility of revolution and the dependence on foreign economic assistance may be greater in these countries than in developed countries. Management seeks to mitigate the risks associated with these considerations through diversification and active professional management.

Forward Commitments

The Fund may invest in forward commitments. The Fund may contract to purchase securities for a fixed price at a future date beyond customary settlement time consistent with the Fund's ability to manage its investment portfolio and meet redemption requests. The Fund may dispose of a commitment prior to settlement if it is appropriate to do so and realize short-term profits or losses upon such sale. Forward commitments involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, or if the other party fails to complete the transaction.

Futures Contracts and Options on Futures

The Fund may enter into futures contracts on securities in which it may invest or on indices comprised of such securities and may purchase and write call and put options on such contracts.

Futures contracts. A financial futures contract is a contract to buy or sell a specified quantity of financial instruments such as U.S. Treasury bills, notes and bonds at a specified future date at a price agreed upon when the contract is made. An index futures contract is a contract to buy or sell specified units of an index at a specified future date at a price agreed upon when the contract is made. The value of a unit is based on the current value of the index. Under such contracts no delivery of the actual securities making up the index takes place. Rather, upon expiration of the contract, settlement is made by exchanging cash in an amount equal to the difference between the contract price and the closing price of the index at expiration, net of variation margin previously paid. Futures contracts are traded in the United States only on commodity exchanges or boards of trade — known as “contract markets” — approved for such trading by the Commodity Futures Trading Commission (the “CFTC”), and must be executed through a futures commission merchant or brokerage firm, which is a member of the relevant contract market.

Although many futures contracts by their terms call for actual delivery or acceptance of commodities or securities, in most cases the contracts are closed out before the settlement date without the making or taking of delivery, but rather by entering into an offsetting contract (a “closing transaction”). Upon entering into a futures contract, the Fund is required to deposit initial margin with the futures broker. The initial margin serves as a “good faith” deposit that the Fund will honor its potential future commitments. Subsequent payments (called “variation margin” or “maintenance margin”) to and from the broker are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking to the market.” If the Fund is unable to enter into a closing transaction, the amount of the Fund's potential loss may be unlimited. Futures contracts also involve brokerage costs.

The Fund will not commit more than 5% of the market value of its total assets to initial margin deposits on futures and premiums paid for options on futures.

Registration under the Commodity Exchange Act. The Fund is operated by the Adviser, which has claimed an exclusion from the definition of the term “commodity pool operator” with respect to the Fund, under the Commodity Exchange Act (the “CEA”), and therefore, is not subject to registration or regulation as a commodity pool operator under the CEA. As a result, the Fund is limited in their ability to trade instruments subject to the CFTC's jurisdiction, including commodity futures (which include futures on broad-based securities indexes, interest rate futures and currency futures), options on commodity futures, certain swaps or other investments (whether directly or indirectly through investments in other investment vehicles).

Under this exclusion, the Fund must satisfy one of the following two trading limitations whenever it enters into a new commodity trading position: (1) the aggregate initial margin and premiums required to establish the Fund's positions in CFTC-regulated instruments may not exceed 5% of the liquidation value of the Fund's portfolio (after accounting for unrealized profits and unrealized losses on any such investments); or (2) the aggregate net notional value of such instruments, determined at the time the most recent position was established, may not exceed 100% of the liquidation value of the Fund's portfolio (after accounting for unrealized profits and unrealized losses on any such positions). The Fund would not be required to consider its exposure to such instruments if they were held for “bona fide hedging” purposes, as such term is defined in the rules of the CFTC. In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the markets for CFTC-regulated instruments.

Options on futures contracts. In return for the premium paid, options on futures contracts give the purchaser the right to assume a position in a futures contract at the specified option exercise price at any time during the exercisable period of the option. Options on futures are similar to options on securities except that options on futures give the purchaser the right, in return for the premium paid, to assume a position in a futures contract (a long position if the option is a call and a short position if the option is a put) at a specified exercise price at any time during the exercisable period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's futures margin account which represents the amount by which the market price of the futures contract, at exercise, exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures. If an option is exercised on the last trading day prior to its expiration date, the settlement will be made entirely in cash. Purchasers of options who fail to exercise their options prior to the expiration date suffer a loss of the premium paid.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers' requirements similar to those described above in connection with the discussion of futures contracts.

Risks of transactions in futures contracts and related options. Successful use of futures contracts by the Fund is subject to the Adviser's ability to predict movements in various factors affecting financial markets. Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

The use of options and futures strategies involves the risk of imperfect correlation among movements in the prices of the securities underlying the futures and options purchased and sold by the Fund, of the options and futures contracts themselves, and, in the case of hedging transactions, of the securities which are the subject of a hedge. The successful use of these strategies further depends on the ability of the Adviser to forecast interest rates and market movements correctly.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution by exchanges of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a position held by the Fund, the Fund may seek to close out such a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid market. It is not certain that this market will develop or continue to exist for a particular futures contract or option. Reasons for the absence of a liquid market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the market on that exchange for such contracts or options (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would likely continue to be exercisable in accordance with their terms.

The CFTC and certain futures exchanges have established (and continue to evaluate and revise) limits, referred to as “position limits,” on the maximum net long or net short positions which any person or entity may hold or control in particular options and futures contracts. In addition, federal position limits apply to swaps that are economically equivalent to futures contracts on certain agricultural, metals and energy commodities. Unless an exemption applies, all positions owned or controlled by the same person or entity, even if in different accounts, must be aggregated for purposes complying with position limits. It is possible that positions of different clients managed by the Adviser and its affiliates may be aggregated for this purpose. Therefore, the trading decisions of the Adviser may have to be modified and positions held

by the Fund may have to be liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of the Fund. A violation of position limits could also lead to regulatory action materially adverse to the Fund's investment strategy.

Futures and options transactions on markets located outside the United States, including markets formally linked to a United States market, may be subject to regulations which offer different or diminished protection to the Fund and its investors. Further, United States regulatory authorities may be unable to compel the enforcement of the rules of regulatory authorities or markets in non-United States jurisdictions where transactions for the Fund may be effected.

U.S. Treasury security futures contracts and options. Some U.S. Treasury security futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of U.S. Treasury security called for in the contract at a specified date and price; others may be settled in cash. Options on U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a U.S. Treasury security futures contract at the specified option exercise price at any time during the exercisable period of the option.

Successful use of U.S. Treasury security futures contracts by the Fund is subject to the Adviser's ability to predict movements in the direction of interest rates and other factors affecting markets for debt securities. For example, if the Fund has sold U.S. Treasury security futures contracts in order to hedge against the possibility of an increase in interest rates which would adversely affect the values of securities held in its portfolio, and the prices of the Fund's securities increase instead as a result of a decline in interest rates, the Fund will lose part or all of the benefit of the increased value of its securities which it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily maintenance margin requirements at a time when it may be disadvantageous to do so.

There is also a risk that price movements in U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for particular securities. For example, if the Fund has hedged against a decline in the values of tax-exempt securities held by it by selling Treasury security futures and the values of Treasury securities subsequently increase while the values of the Fund's tax-exempt securities decrease, the Fund would incur losses on both the Treasury security futures contracts written by it and the tax-exempt securities held in its portfolio.

Government Mortgage-Related Securities

The Government National Mortgage Association (“GNMA” or “Ginnie Mae”) is the principal federal government guarantor of mortgage-related securities. GNMA is a wholly owned U.S. Government corporation within the Department of Housing and Urban Development. It guarantees, with the full faith and credit of the United States, full and timely payment of all monthly principal and interest on its mortgage-related securities. GNMA pass-through securities are considered to have a relatively low risk of default in that (1) the underlying mortgage loan portfolio is comprised entirely of government-backed loans and (2) the timely payment of both principal and interest on the securities is guaranteed by the full faith and credit of the U.S. Government, regardless of whether they have been collected. GNMA pass-through securities are, however, subject to the same interest rate risk as comparable privately issued mortgage-related securities. Therefore, the effective maturity and market value of the Fund's GNMA securities can be expected to fluctuate in response to changes in interest rate levels.

Residential mortgage loans are also pooled by the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”), a corporate instrumentality of the U.S. Government. The mortgage loans in FHLMC's portfolio are not government backed; FHLMC, not the U.S. Government, guarantees the timely payment of interest and ultimate collection of principal on FHLMC securities. FHLMC also issues guaranteed mortgage certificates, on which it guarantees semiannual interest payments and a specified minimum annual payment of principal.

The Federal National Mortgage Association (“FNMA” or “Fannie Mae”) is a government-sponsored corporation owned entirely by private stockholders. It is subject to general regulation by the Secretary of Housing and Urban Development. FNMA purchases residential mortgages from a list of approved seller/servicers, which include savings and loan associations, savings banks, commercial banks, credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest only by FNMA, not the U.S. Government.

High Yield Securities

The Fund may invest a portion of their assets in high yield debt securities (commonly known as “junk bonds”). Investment in high yield securities generally provides greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and credit risk. These high yield securities are regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and

interest payments. Analysis of the creditworthiness of issuers of debt securities that are high yield may be more complex than for issuers of higher quality debt securities. In addition, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, but can also be issued by governments. Such issuers are generally less able than more financially stable issuers to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial.

Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero-coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of the Fund than a fund that invests in higher-rated securities.

Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual issuer developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by the Fund.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield security, and could adversely affect the daily net asset value (“NAV”) per share of the Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available. However, an Index seeks to include primarily high yield securities that the Index provider believes have greater liquidity than the broader high yield securities market as a whole.

The use of credit ratings as a principal method of selecting high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated.

Illiquid Securities

The Fund may invest in illiquid investments. The Fund will invest no more than 15% of its net assets in illiquid investments, including repurchase agreements and time deposits of more than seven days' duration. The absence of a regular trading market for illiquid investments imposes additional risks on investments in these securities. Illiquid investments may be difficult to value and may often be disposed of only after considerable expense and delay.

The SEC has adopted a liquidity risk management rule (the “Liquidity Rule”) that requires the Fund to establish a liquidity risk management program (the “LRMP”). The Trustees, including a majority of the Independent Trustees (defined infra), have designated the Adviser to administer the Fund's LRMP. Under the LRMP, the Adviser assesses, manages, and periodically reviews the Fund's liquidity risk. The Liquidity Rule defines “liquidity risk” as the risk that the Fund could not meet requests to redeem shares issued by the Fund without significant dilution of remaining investors' interests in the Fund. The liquidity of the Fund's portfolio investments is determined based on relevant market, trading and investment-specific considerations under the LRMP. To the extent that an investment is deemed to be an illiquid investment or a less liquid investment, the Fund can expect to be exposed to greater liquidity risk. While the liquidity risk management program attempts to assess and manage liquidity risk, there is no guarantee it will be effective in its operations and may not reduce the liquidity risk inherent in the Fund's investments. The SEC has recently proposed amendments to Rule 22e-4 under the 1940 Act and Rule 22c-1 under the 1940 Act that, if adopted, would, among other things, cause more investments to be treated as illiquid, and could prevent the Fund from investing in securities that the Adviser believes are appropriate or desirable.

Infrastructure-Related Companies Risk

Infrastructure-related companies include companies that primarily own, manage, develop and/or operate infrastructure assets, including transportation, utility, energy and/or telecommunications assets. Infrastructure-related businesses are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, insurance costs, costs associated with environmental and other

regulations, the effects of an economic slowdown, surplus capacity or technological obsolescence, industry competition, labor relations, rate caps or rate changes, uncertainties concerning availability of fuel at reasonable prices, the effects of energy conservation policies, natural disasters, terrorist attacks and other factors. Certain infrastructure-related entities, particularly telecommunications and utilities companies, are subject to extensive regulation by various governmental authorities. The costs of complying with governmental regulations, delays or failures to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect infrastructure-related companies. Infrastructure-related companies may also be affected by service interruption and/or legal challenges due to environmental, operational or other conditions or events, and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. There is also the risk that corruption may negatively affect publicly-funded infrastructure projects, especially in non-U.S. markets, resulting in work stoppage, delays and cost overruns. Other risks associated with infrastructure-related companies include uncertainties resulting from such companies' diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Investment Grade Bonds

The Fund may invest in corporate notes and bonds that are rated investment-grade by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, are of comparable quality to the rated securities described above, as determined by the Adviser, in accordance with procedures established by the Board of Trustees. Investment-grade securities include securities rated Baa or higher by Moody's or BBB- or higher by S&P (and securities of comparable quality); securities rated Baa by Moody's or BBB by S&P may have speculative characteristics.

Lending of Fund Securities

The Fund may lend portfolio securities to certain creditworthy borrowers in U.S. and non-U.S. markets in an amount not to exceed 40% of the value of its net assets. The borrowers provide collateral that is marked to market daily in an amount at least equal to the current market value of the securities loaned. The Fund may terminate a loan at any time and obtain the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities. The Fund cannot vote proxies for securities on loan, but may recall loans to vote proxies if a material issue affecting the Fund's economic interest in the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities. Distributions received on loaned securities in lieu of dividend payments (i.e., substitute payments) would not be considered qualified dividend income.

With respect to loans that are collateralized by cash, the borrower typically will be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain high quality short-term instruments either directly on behalf of the lending Fund or through one or more joint accounts or funds, which may include those managed by the Adviser. The Fund could lose money due to a decline in the value of collateral provided for loaned securities or any investments made with cash collateral.

The Fund may pay a portion of the interest or fees earned from securities lending to a borrower as described above, and to one or more securities lending agents approved by the Board of Trustees of the Trust (the “Board”) who administer the lending program for the Fund in accordance with guidelines approved by the Board. In such capacity, the lending agent provides the following services to the Fund in connection with the Fund's securities lending activities: (i) locating borrowers among an approved list of prospective borrowers; (ii) causing the delivery of loaned securities from the Fund to borrowers; (iii) monitoring the value of loaned securities, the value of collateral received, and other lending parameters; (iv) seeking additional collateral, as necessary, from borrowers; (v) receiving and holding collateral from borrowers, and facilitating the investment and reinvestment of all or substantially all cash collateral in an investment vehicle designated by the Fund; (vi) returning collateral to borrowers; (vii) facilitating substitute dividend, interest, and other distribution payments to the Fund from borrowers; (viii) negotiating the terms of each loan of securities, including but not limited to the amount of any loan premium, and monitoring the terms of securities loan agreements with prospective borrowers for consistency with the requirements of the Fund's Securities Lending Authorization Agreement; (ix) selecting securities, including amounts (percentages), to be loaned; (x) recordkeeping and accounting servicing; and (xi) arranging for return of loaned securities to the Fund in accordance with the terms of the Securities Lending Authorization Agreement. State Street Bank and Trust Company (“State Street”), an affiliate of the Trust, has been approved by the Board to serve as securities lending agent for the Fund and the Trust has entered into an agreement with State Street for such services. Among other matters, the Trust has agreed to indemnify State Street for certain liabilities. State Street has received an order of exemption from the SEC

under Sections 17(a), 17(d) and 12(d)(1) under the 1940 Act to serve as the lending agent for affiliated investment companies such as the Trust, to invest the cash collateral received from loan transactions in an affiliated cash collateral fund and to receive a fee based on a share of the revenue generated from such transactions.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process especially so in certain international markets such as Taiwan), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), risk of loss of collateral, credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral (or the proceeds of its liquidation) or in recovering the loaned securities. In the event a borrower does not return the Fund's securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. Although State Street has agreed to provide the Fund with indemnification in the event of a borrower default, the Fund is still exposed to the risk of losses in the event a borrower does not return the Fund's securities as agreed. For example, delays in recovery of lent securities may cause the Fund to lose the opportunity to sell the securities at a desirable price with guaranteed delivery provisions.

In response to market events, the SEC has adopted new reporting requirements for securities loans which include the public dissemination of certain information about such loans. These new reporting requirements may negatively impact the Fund's ability to execute certain of its investment strategies.

Market Disruption and Geopolitical Risk

The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. War, terrorism, and related geopolitical events have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets generally. Likewise, natural and environmental disasters, epidemics or pandemics, such as that caused by COVID-19, and systemic market dislocations may be highly disruptive to economies and markets. Those events as well as other changes in non-U.S. and domestic economic and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund's investments. Given the increasing interdependence between global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the U.S. Continuing uncertainty as to the status of the euro and the Economic and Monetary Union of the European Union (the “EMU”) has created significant volatility in currency and financial markets generally. Any partial or complete dissolution of the EMU, or any continued uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Fund's investments. The EU faces challenges related to member states seeking to change their relationship with the European Union, exemplified by the United Kingdom's (“UK”) withdrawal from the EU in 2020 (an event commonly known as “Brexit”). Brexit has resulted in volatility in European and global markets and could have negative long-term impacts on financial markets in the UK and throughout Europe. There is still considerable uncertainty relating to the potential consequences associated with the exit, including how negotiations for new trade agreements will be conducted and whether the U.K.'s exit will increase the likelihood of other countries also departing the EU.

Securities markets may be susceptible to market manipulation or other fraudulent trade practices, which could disrupt the orderly functioning of these markets or adversely affect the value of investments traded in these markets, including investments of the Fund.

For example, London Interbank Offered Rate (“LIBOR”) was the offered rate at which major international banks could obtain wholesale, unsecured funding. Certain of the Fund's investments, payment obligations, financing terms and other transactions (including certain derivatives transactions) have historically been tied to LIBOR. In connection with the global transition away from LIBOR led by regulators and market participants, LIBOR was last published on a representative basis at the end of June 2023. Alternative reference rates to LIBOR have been established in most major currencies (e.g., the Secured Overnight Financing Rate for U.S. dollar LIBOR and the Sterling Overnight Index Average for GBP LIBOR) and the transition to new reference rates continues. The transition away from LIBOR to the use of replacement rates has gone relatively smoothly but the full impact of the transition on the Fund or the financial instruments in which the Fund invest cannot yet be fully determined. In addition, the Fund's investments, payment obligations, financing terms and other transactions (including certain derivatives transactions) may be tied to other floating rates such as Euro Interbank Offered Rate (“EURIBOR”) and other similar types of reference rates including as a result of the transition away from LIBOR to new alternative reference rates (each, a “Reference Rate”). Such Reference Rates as well as other types of rates and

indices are classed as “benchmarks” and have been the subject of ongoing national and international regulatory reform, including under the European Union regulation on indices used as benchmarks in financial instruments and financial contracts (known as the “Benchmarks Regulation”). The Benchmarks Regulation has been enacted into United Kingdom law by virtue of the European Union (Withdrawal) Act 2018 (as amended), subject to amendments made by the Benchmarks (Amendment and Transitional Provision) (EU Exit) Regulations 2019 (SI 2019/657) and other statutory instruments. Following the implementation of these reforms, the manner of administration of benchmarks has changed and may further change in the future, with the result that relevant benchmarks may perform differently than in the past, the use of benchmarks that are not compliant with the new standards by certain supervised entities may be restricted, and certain benchmarks may be eliminated entirely. Such changes could cause increased market volatility and disruptions in liquidity for instruments that rely on or are impacted by such benchmarks. Additionally, there could be other consequences which cannot be predicted.

Recent political activity in the U.S. has increased the risk that the U.S. could default on some or any of its obligations. While it is impossible to predict the consequences of such an unprecedented event, it is likely that a default by the U.S. would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Fund's investments. Similarly, political events within the U.S. at times have resulted, and may in the future result, in a shutdown of government services, which could negatively affect the U.S. economy, decrease the value of many Fund investments, and increase uncertainty in or impair the operation of the U.S. or other securities markets. To the extent the Fund has focused its investments in the stock market index of a particular region, adverse geopolitical and other events could have a disproportionate impact on the Fund.

Market Turbulence Resulting from Infectious Illness

A widespread outbreak of an infectious illness, such as COVID-19, may lead to governments and businesses world-wide taking aggressive measures, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations. As occurred in the wake of COVID-19, the spread of such an illness may result in the disruption of and delays in the delivery of healthcare services and processes, the cancellation of organized events and educational institutions, the disruption of production and supply chains, a decline in consumer demand for certain goods and services, and general concern and uncertainty, all of which may contribute to increased volatility in global markets. COVID-19, and other epidemics and pandemics that may arise in the future, could adversely affect the economies of many nations, the global economy, individual companies, economic sectors and industries, and capital markets in ways that cannot be foreseen at the present time. In addition, the impact of infectious diseases in developing or emerging market countries may be greater due to limited health care resources. Political, economic and social stresses caused by an infectious illness also may exacerbate other pre-existing political, social and economic risks in certain countries. The duration of such an illness and its effects cannot be determined at this time, but the effects could be present for an extended period of time.

The Fund, except for the Emerging Markets Equity Index Fund and the Small/Mid Cap Equity Index Fund, may enter into “forward roll” transactions with respect to mortgage-related securities issued by GNMA, FNMA or FHLMC. In a forward roll transaction, the Fund will sell a mortgage-related security to a bank or other permitted entity and simultaneously agree to repurchase a similar security from the institution at a later date at an agreed upon price. The mortgage securities that are repurchased will typically bear the same interest rate as those sold, but generally will be collateralized by different pools of mortgages with different prepayment histories than those sold. The Fund that engages in a forward roll transaction forgoes principal and interest paid on the securities sold during the roll period, but is compensated by the difference between the current sales price and the lower forward price for the future purchase. In addition, the Fund earns interest by investing the transaction proceeds during the roll period. A forward roll transaction may create investment leverage. The Fund is subject to the risk that the value of securities to be purchased pursuant to a forward roll transaction will decline over the roll period, and that the Fund's counterparty may be unwilling or unable to perform its obligations to the Fund.

Mortgage-Related Securities

The Fund, except for the Emerging Markets Equity Index Fund, may invest in mortgage-related securities. Mortgage-related securities represent an interest in a pool of, or are secured by, mortgage loans. Mortgage-related securities may be issued or guaranteed by (i) U.S. Government agencies or instrumentalities such as GNMA, FNMA and FHLMC or (ii) other issuers, including private companies.

Many mortgage-related securities provide regular payments which consist of interest and, in most cases, principal. In contrast, other forms of debt securities normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. In effect, payments on many mortgage-related securities are a “pass-through” of the payments made by the individual borrowers on their mortgage loans, net of any fees paid to the issuer or guarantor of such securities.

Besides the scheduled repayment of principal, repayments of principal may result from the voluntary prepayment, refinancing or foreclosure of the underlying mortgage loans. If property owners make unscheduled prepayments of their mortgage loans, these prepayments will typically result in early payment of the applicable mortgage-related securities. The occurrence of mortgage prepayments is affected by a variety of factors, including the level of interest rates, general economic conditions, the location and age of the mortgage, and other social and demographic conditions. During periods of falling interest rates, the rate of mortgage prepayments tends to increase, thereby tending to decrease the life of mortgage-related securities. During periods of rising interest rates, the rate of mortgage prepayments usually decreases, thereby tending to increase the life of mortgage-related securities.

Because of the possibility of prepayments (and due to scheduled repayments of principal), mortgage-related securities are less effective than other types of securities as a means of “locking in” attractive long-term interest rates. Prepayments would have to be reinvested at lower rates. As a result, these securities may have less potential for capital appreciation during periods of declining interest rates than other securities of comparable maturities, although they may have a similar risk of decline in market value during periods of rising interest rates. Prepayments may also significantly shorten the effective maturities of these securities, especially during periods of declining interest rates. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing the volatility of the Fund.

Collateralized mortgage obligations (“CMOs”) may be issued by a U.S. Government agency or instrumentality or by a private issuer. CMOs are typically structured with classes or series that have different maturities and are generally retired in sequence. Each class of obligations receives periodic interest payments according to its terms. However, monthly principal payments and any prepayments from the collateral pool are generally paid first to the holders of the most senior class. Thereafter, payments of principal are generally allocated to the next most senior class of obligations until that class of obligations has been fully repaid. Any or all classes of obligations of a CMO may be paid off sooner than expected because of an increase in the payoff speed of the pool. Changes in prepayment rates may have significant effects on the values and the volatility of the various classes and series of a CMO. Payment of interest or principal on some classes or series of a CMO may be subject to contingencies or some classes or series may bear some or all of the risk of default on the underlying mortgages.

Ongoing developments in the residential and commercial mortgage markets may have additional consequences for the market for mortgage-backed securities. During the periods of deteriorating economic conditions, such as recessions or periods of rising unemployment, delinquencies and losses generally increase, sometimes dramatically, with respect to securitizations involving mortgage loans. Many sub-prime mortgage pools have become distressed during the periods of economic distress and may trade at significant discounts to their face value during such period.

Stripped mortgage-related securities are usually structured with two classes that receive different portions of the interest and principal distributions on a pool of mortgage loans. The yield to maturity on an interest only or “IO” class of stripped mortgage-related securities is extremely sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying assets. A rapid rate of principal prepayments may have a measurable adverse effect on the Fund's yield to maturity to the extent it invests in IOs. If the assets underlying the IO experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully, or at all, its initial investment in these securities. Conversely, principal only securities or “POs” tend to increase in value if prepayments are greater than anticipated and decline if prepayments are slower than anticipated. The secondary market for stripped mortgage-related securities may be more volatile and less liquid than that for other mortgage-related securities, potentially limiting the Fund's ability to buy or sell those securities at any particular time.

Municipal and Municipal-Related Securities

Municipal securities may bear fixed, floating or variable rates of interest or may be zero-coupon securities. Municipal securities are generally of two types: general obligations and revenue obligations. General obligations are backed by the full faith and credit of the issuer. These securities include tax anticipation notes, bond anticipation notes, general obligation bonds and commercial paper. Revenue obligations are backed by the revenues generated from a specific project or facility

and include industrial development bonds and private activity bonds. Tax anticipation notes are issued to finance working capital needs of municipalities and are generally issued in anticipation of future tax revenues. Bond anticipation notes are issued in expectation of the issuer obtaining longer-term financing.

Options

The Fund may purchase and sell put and call options to enhance investment performance and to protect against changes in market prices. There is no assurance that the Fund's use of put and call options will achieve its desired objective, and the Fund's use of options may result in losses to the Fund.

Covered call options. The Fund may write (i.e., sell) covered call options to realize a greater current return through the receipt of premiums than it would realize on its securities alone. Such option transactions may also be used as a limited form of hedging against a decline in the price of securities owned by the Fund.

A call option gives the holder the right to purchase, and obligates the writer to sell, a security at the exercise price at any time before the expiration date. A call option is “covered” if the writer, at all times while obligated as a writer, either owns the underlying securities (or comparable securities satisfying the cover requirements of the securities exchanges), or has the right to acquire such securities through immediate conversion of securities. The Fund may write covered call options or uncovered call options.

The Fund will receive a premium from writing a call option, which increases the Fund's return on the underlying security in the event the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security.

In return for the premium received when it writes a covered call option, the Fund gives up some or all of the opportunity to profit from an increase in the market price of the securities covering the call option during the life of the option. The Fund retains the risk of loss should the price of such securities decline. If the option expires unexercised, the Fund realizes a gain equal to the premium, which may be offset by a decline in price of the underlying security. If the option is exercised, the Fund realizes a gain or loss equal to the difference between the Fund's cost for the underlying security and the proceeds of sale (exercise price minus commissions) plus the amount of the premium.

The Fund may terminate a call option that it has written before it expires by entering into a closing purchase transaction. The Fund may enter into closing purchase transactions in order to free itself to sell the underlying security or to write another call on the security, realize a profit on a previously written call option, or protect a security from being called in an unexpected market rise. Any profits from a closing purchase transaction may be offset by a decline in the value of the underlying security. Conversely, because increases in the market price of a call option will generally reflect increases in the market price of the underlying security, any loss resulting from a closing purchase transaction is likely to be offset in whole or in part by unrealized appreciation of the underlying security owned by the Fund.

Uncovered call options. Writing uncovered call options may enable the Fund to realize income without committing capital to the ownership of the underlying securities or instruments, however writing uncovered calls are riskier than writing covered calls because there is no underlying security held by the Fund that can act as a partial hedge. When the Fund has written an uncovered call option, the Fund will not necessarily hold securities offsetting the risk to the Fund. As a result of writing a call option without holding the underlying the securities, if the call option were exercised, the Fund might be required to purchase the security that is the subject of the call at the market price at the time of exercise. The Fund's exposure on such an option is theoretically unlimited. There is also a risk, especially with less liquid preferred and debt securities, that the security may not be available for purchase. Uncovered calls have speculative characteristics.

Covered put options. The Fund may write covered put options in order to enhance its current return. Such options transactions may also be used as a limited form of hedging against an increase in the price of securities that the Fund plans to purchase. A put option gives the holder the right to sell, and obligates the writer to buy, a security at the exercise price at any time before the expiration date. A put option may be “covered” if the writer earmarks or otherwise segregates liquid assets equal to the price to be paid if the option is exercised minus margin on deposit.

By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then current market value, resulting in a potential capital loss unless the security later appreciates in value.

The Fund may terminate a put option that it has written before it expires by entering into a closing purchase transaction. Any loss from this transaction may be partially or entirely offset by the premium received on the terminated option.

Purchasing put and call options. The Fund may also purchase put options to protect portfolio holdings against a decline in market value. This protection lasts for the life of the put option because the Fund, as a holder of the option, may sell the underlying security at the exercise price regardless of any decline in its market price. In order for a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs that the Fund must pay. These costs will reduce any profit the Fund might have realized had it sold the underlying security instead of buying the put option.

The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security's market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

The Fund may also purchase put and call options to attempt to enhance its current return.

Options on foreign securities. The Fund may purchase and sell options on foreign securities if the Adviser believes that the investment characteristics of such options, including the risks of investing in such options, are consistent with the Fund's investment objective. It is expected that risks related to such options will not differ materially from risks related to options on U.S. securities. However, position limits and other rules of foreign exchanges may differ from those in the United States. In addition, options markets in some countries, many of which are relatively new, may be less liquid than comparable markets in the United States.

Options on securities indices. The Fund may write or purchase options on securities indices. Index options are similar to options on individual securities in that the purchaser of an index option acquires the right to buy (in the case of a call) or sell (in the case of a put), and the writer undertakes the obligation to sell or buy (as the case may be), units of an index at a stated exercise price during the term of the option. Instead of the right to take or make actual delivery of securities, the holder of an index option has the right to receive a cash “exercise settlement amount.” This amount is equal to the amount by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of the exercise, multiplied by a fixed “index multiplier.”

Price movements in securities which the Fund owns or intends to purchase probably will not correlate perfectly with movements in the level of a securities index and, therefore, if the Fund uses an option for hedging purposes, it bears the risk of a loss on a securities index option which is not completely offset by movements in the price of such securities. Because securities index options are settled in cash, a call writer cannot determine the amount of its settlement obligations in advance and, unlike call writing on a specific security, cannot provide in advance for, or cover, its potential settlement obligations by acquiring and holding underlying securities. The Fund may, however, cover call options written on a securities index by holding a mix of securities which substantially replicate the movement of the index or by holding a call option on the securities index with an exercise price no higher than the call option sold.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on an index involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options plus transactions costs. The writing of a put or call option on an index involves risks similar to those risks relating to the purchase or sale of index futures contracts.

Risks involved in the use of options. The successful use of the Fund's options strategies depends on the ability of the Adviser to forecast correctly interest rate and market movements. For example, if the Fund were to write a call option based on the Adviser's expectation that the price of the underlying security would fall, but the price were to rise instead, the Fund could be required to sell the security upon exercise at a price below the current market price. Similarly, if the Fund were to write a put option based on the Adviser's expectation that the price of the underlying security would rise, but the price were to fall instead, the Fund could be required to purchase the security upon exercise at a price higher than the current market price.

When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying security, since the Fund will not realize a loss if the security's price does not change.

The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A market may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events — such as volume in excess of trading or clearing capability — were to interrupt its normal operations.

A market may at times find it necessary to impose restrictions on particular types of options transactions, such as opening transactions. For example, if an underlying security ceases to meet qualifications imposed by the market or the Options Clearing Corporation, new series of options on that security will no longer be opened to replace expiring series, and opening transactions in existing series may be prohibited. If an options market were to become unavailable, the Fund as a holder of an option would be able to realize profits or limit losses only by exercising the option, and the Fund, as option writer, would remain obligated under the option until expiration or exercise.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with considerable losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation or options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If the Options Clearing Corporation were to determine that the available supply of an underlying security appears insufficient to permit delivery by the writers of all outstanding calls in the event of exercise, it may prohibit indefinitely the exercise of put options. The Fund, as holder of such a put option, could lose its entire investment if the prohibition remained in effect until the put option's expiration.

Foreign-traded options are subject to many of the same risks presented by internationally-traded securities. In addition, because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

Over-the-counter (“OTC”) options purchased by the Fund and assets held to cover OTC options written by the Fund may, under certain circumstances, be considered illiquid securities for purposes of any limitation on the Fund's ability to invest in illiquid securities.

Other Asset-Backed Securities

In addition to the mortgage related securities discussed above, the Fund may invest in asset-backed securities that are not mortgage-related. Asset-backed securities other than mortgage-related securities represent undivided fractional interests in pools of instruments, such as consumer loans, and are typically similar in structure to mortgage-related pass-through securities. Payments of principal and interest are passed through to holders of the securities and are typically supported by some form of credit enhancement, such as a letter of credit, surety bond, limited guarantee by another entity, or by priority to certain of the borrower's other securities. The degree of credit-enhancement, if any, varies, applying only until exhausted and generally covering only a fraction of the security's par value.

The value of such asset-backed securities is affected by changes in the market's perception of the asset backing the security, changes in the creditworthiness of the servicing agent for the instrument pool, the originator of the instruments, or the financial institution providing any credit enhancement and the expenditure of any portion of any credit enhancement. The risks of investing in asset-backed securities are ultimately dependent upon payment of the underlying instruments by the obligors, and the Fund would generally have no recourse against the obligee of the instruments in the

event of default by an obligor. The underlying instruments are subject to prepayments which shorten the duration of asset-backed securities and may lower their return, in generally the same manner as described above for prepayments of pools of mortgage loans underlying mortgage-related securities. During periods of deteriorating economic conditions, such as recessions or periods of rising unemployment, delinquencies and losses generally increase, sometimes dramatically, with respect to securitizations involving loans, sales contracts, receivables and other obligations underlying asset-backed securities.

Pre-Refunded Municipal Securities

The interest and principal payments on pre-refunded municipal securities are typically paid from the cash flow generated from an escrow fund consisting of U.S. Government securities. These payments have been “pre-refunded” using the escrow fund.

Private Placements and Restricted Securities

The Fund may invest in securities that are purchased in private placements and, accordingly, are subject to restrictions on resale as a matter of contract or under federal securities laws. While such private placements may offer attractive opportunities for investment not otherwise available on the open market, the securities so purchased are often “restricted securities,” i.e., securities which cannot be sold to the public without registration under the Securities Act of 1933 (the “Securities Act”) or the availability of an exemption from registration (such as Rules 144 or 144A), or which are not readily marketable because they are subject to other legal or contractual delays in or restrictions on resale. Generally speaking, restricted securities may be sold only to qualified institutional buyers, or in a privately negotiated transaction to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met pursuant to an exemption from registration, or in a public offering for which a registration statement is in effect under the Securities Act.

Because there may be relatively few potential purchasers for such investments, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when the Adviser believes it advisable to do so or may be able to sell such securities only at prices lower than if such securities were more widely held. Market quotations for such securities are generally less readily available than for publicly traded securities. The absence of a trading market can make it difficult to ascertain a market value for such securities for purposes of computing the Fund's net asset value, and the judgment of the Adviser may at times play a greater role in valuing these securities than in the case of publicly traded securities. Disposing of such securities, which may be illiquid investments, can involve time-consuming negotiation and legal expenses, and it may be difficult or impossible for the Fund to sell them promptly at an acceptable price. The Fund may have to bear the extra expense of registering such securities for resale and the risk of substantial delay in effecting such registration.

The Fund may be deemed to be an “underwriter” for purposes of the Securities Act when selling restricted securities to the public, and in such event the Fund may be liable to purchasers of such securities if the registration statement prepared by the issuer, or the prospectus forming a part of it, is materially inaccurate or misleading.

Purchase of Other Investment Company Shares

The Fund may, to the extent permitted under the 1940 Act and the rules thereunder, invest in shares of other investment companies, which include funds managed by SSGA FM, which invest exclusively in money market instruments or in investment companies with investment policies and objectives which are substantially similar to those of the Fund. These investments may be made temporarily, for example, to invest uncommitted cash balances or, in limited circumstances, to assist in meeting shareholder redemptions, or as long-term investments. In general, the 1940 Act prohibits the Fund from acquiring more than 3% of the voting shares of any one other investment company, and prohibits the Fund investing more than 5% of its total assets in the securities of any one other investment company or more than 10% of its total assets in securities of other investment companies in the aggregate. The percentage limitations above apply to investments in any investment company. Pursuant to rules adopted by the SEC, the Fund may invest in excess of these limitations if the Fund and the investment company in which the Fund would like to invest comply with certain conditions. Certain of the conditions do not apply if the Fund is investing in shares issued by affiliated funds. In addition, the Fund may invest in shares issued by money market funds, including certain unregistered money market funds, in excess of the limitations. The Fund's investments in another investment company will be subject to the risks of the purchased investment company's portfolio securities. The Fund's shareholders must bear not only their proportionate share of the Fund's fees and expenses, but they also must bear indirectly the fees and expenses of the other investment company.

Real Estate Investment Trusts (“REITs”)

The Fund may invest in REITs. REITs pool investors' funds for investment primarily in income producing real estate or real estate loans or interests. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets, and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year. REITs can generally be classified as Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs, which invest the majority of their assets directly in real property, derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs, which invest the majority of their assets in real estate mortgages, derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both Equity REITs and Mortgage REITs. The Fund will not invest in real estate directly, but only in securities issued by real estate companies. However, the Fund may be subject to risks similar to those associated with the direct ownership of real estate (in addition to securities markets risks) because of its policy of concentration in the securities of companies in the real estate industry. These include declines in the value of real estate, risks related to general and local economic conditions, dependency on management skill, heavy cash flow dependency, possible lack of availability of mortgage funds, overbuilding, extended vacancies of properties, increased competition, increases in property taxes and operating expenses, changes in zoning laws, losses due to costs resulting from the clean-up of environmental problems, liability to third-parties for damages resulting from environmental problems, casualty or condemnation losses, limitations on rents, changes in neighborhood values, the appeal of properties to tenants and changes in interest rates. Investments in REITs may subject Fund shareholders to duplicate management and administrative fees.

In addition to these risks, Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while Mortgage REITs may be affected by the quality of any credit extended. Further, Equity and Mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and Mortgage REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, if applicable, Equity and Mortgage REITs could possibly fail to qualify for the favorable tax treatment available to REITs under the Code, or to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower's or a lessee's ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Repurchase Agreements

The Fund may enter into repurchase agreements with banks, other financial institutions, such as broker-dealers, and other institutional counterparties. Under a repurchase agreement, the Fund purchases securities from a financial institution that agrees to repurchase the securities at the Fund's original purchase price plus interest within a specified time. The Fund will limit repurchase transactions to those member banks of the Federal Reserve System, broker-dealers and other financial institutions whose creditworthiness the Adviser considers satisfactory. Should the counterparty to a transaction fail financially, the Fund may encounter delay and incur costs before being able to sell the securities, or may be prevented from realizing on the securities. Further, the amount realized upon the sale of the securities may be less than that necessary to fully compensate the Fund. The SEC has finalized new rules requiring the central clearing of certain repurchase transactions involving U.S. Treasuries. Historically, such transactions have not been required to be cleared and voluntary clearing of such transactions has generally been limited. The new clearing requirements could make it more difficult for the Fund to execute certain investment strategies.

Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements, which are a form of borrowing. Under reverse repurchase agreements, the Fund transfers possession of portfolio securities to financial institutions in return for cash in an amount equal to a percentage of the portfolio securities' market value and agrees to repurchase the securities at a future date by repaying the cash with interest. The Fund retains the right to receive interest and principal payments from the securities. Reverse repurchase agreements involve the risk that the market value of securities sold by the Fund may decline below the price at which it is obligated to repurchase the securities. Reverse repurchase agreements involve the risk that the buyer of the securities sold might be unable to deliver them when the Fund seeks to repurchase the securities. If the buyer files for bankruptcy or becomes insolvent, the Fund may be delayed or prevented from recovering the security that it sold. The SEC has finalized new rules requiring the central clearing of certain repurchase transactions involving U.S. Treasuries. Historically, such transactions have not been required to be cleared and voluntary clearing of such transactions has generally been limited. The new clearing requirements could make it more difficult for the Fund to execute certain investment strategies.

Special Risk Considerations of Investing in China.

The Fund may invest in securities of Chinese issuers. Investing in securities of Chinese issuers, including by investing in A Shares, involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, (i) more frequent (and potentially widespread) trading suspensions and U.S. or foreign government interventions or restrictions with respect to Chinese issuers, which could preclude the Fund from making certain investments or result in the Fund selling investments at disadvantageous times and which may also cause reduced liquidity and increased price volatility in such investments, (ii) currency revaluations and other currency exchange rate fluctuations or blockage, (iii) the nature and extent of intervention by the Chinese government in the Chinese securities markets, whether such intervention will continue and the impact of such intervention or its discontinuation, (iv) the risk of nationalization or expropriation of assets, (v) the risk that the Chinese government may decide not to continue to support economic reform programs, (vi) limitations on the use of brokers, (vii) potentially higher rates of inflation, (viii) the unavailability of consistently-reliable economic data, (ix) the relatively small size and absence of operating history of many Chinese companies, (x) accounting, auditing and financial reporting standards in China are different from U.S. standards and, therefore, disclosure of certain material information may not be available, (xi) greater political, economic, social, legal and tax-related uncertainty, (xii) higher market volatility caused by any potential regional territorial conflicts or natural disasters, (xiii) higher dependence on exports and international trade, (xiv) the risk of increased trade tariffs, sanctions, embargoes and other trade limitations, (xv) restrictions on foreign ownership, (xvi) risks associated with variable interest entity (“VIE”) structures, and (xvii) custody risks associated with investing through programs to access Chinese securities. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events. The liquidity of Chinese securities may shrink or disappear suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.

The Fund may also gain investment exposure to Chinese companies through VIE structures. Such investments are subject to the investment risks associated with the Chinese-based company. The VIE structure enables foreign investors, such as the Fund, to obtain investment exposure to a Chinese company in situations in which the Chinese government has prohibited or limited non-Chinese ownership of such company. The VIE structure does not involve direct equity ownership in a China-based company, but rather involves claims to the China-based company's profits and control of the assets that belong to the China-based company through contractual arrangements. The contractual arrangements in place with the China-based company provide limited ability for the VIE to exercise control over the China-based company and the China-based company's actions may negatively impact the investment value of the VIE. Control over a VIE may also be jeopardized if a natural person who holds the equity interest in the VIE breaches the terms of the contractual arrangements, is subject to legal proceedings, or if any physical instruments such as chops and seals are used without authorization.

Intervention by the Chinese government with respect to the VIE structure could significantly affect the Chinese operating company's performance and thus, the value of the Fund's investment through a VIE structure, as well as the enforceability of the contractual arrangements of the VIE structure. In the event of such an occurrence, the Fund, as a foreign investor, may have little or no legal recourse. If the Chinese government were to determine that the contractual arrangements establishing the VIE structure did not comply with Chinese law or regulations, the Chinese operating company could be subject to penalties, revocation of its business and operating license, or forfeiture of ownership interests. In addition to the risk of government intervention, investments through a VIE structure are subject to the risk that the China-based company (or its officers, directors, or Chinese equity owners) may breach the contractual arrangements, or Chinese law changes in a way that adversely affects the enforceability of the arrangements, or the contracts are otherwise not enforceable under Chinese law, in which case the Fund may suffer significant losses on its investments through a VIE structure with little or no recourse available.

In addition, unexpected political, regulatory and diplomatic events, such as the U.S.-China “trade war” that intensified in 2018, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. The current political climate and the renewal or escalation of a trade war between China and the United States may have an adverse effect on both the U.S. and Chinese economies, including as the result of one country's imposition of tariffs on the other country's products. In addition, sanctions or other investment restrictions could preclude the Fund from investing in certain Chinese issuers or cause the Fund to sell investments at disadvantageous times. Events such as these and their impact on the Fund is difficult to predict and it is unclear whether further tariffs may be imposed or other escalating actions may be taken in the future.

Moreover, the Chinese government is involved in a longstanding dispute with Taiwan that has included threats of invasion. If the political climate between the U.S. and China does not improve or continues to deteriorate, if China were to attempt unification of Taiwan by force, or if other geopolitical conflicts develop or get worse, economies, markets, and individual securities may be severely affected both regionally and globally, and the value of the Fund's assets may go down.

Total Return Swaps, Equity Swaps and Interest Rate Swaps

The Fund may contract with a counterparty to pay a stream of cash flows and receive the total return of an index or a security for purposes of attempting to obtain a particular desired return at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return. The Fund's return on a swap will depend on the ability of its counterparty to perform its obligations under the swap. The Adviser will cause the Fund to enter into swap agreements only with counterparties that would be eligible for consideration as repurchase agreement counterparties under the Fund's repurchase agreement guidelines.

The Fund may enter into interest rate swap transactions with respect to any security they are entitled to hold. Interest rate swaps involve the exchange by the Fund with another party of their respective rights to receive interest, e.g., an exchange of floating rate payments for fixed rate payments. The Fund expect to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio or to protect against any increase in the price of securities it anticipates purchasing at a later date. The Fund generally intend to use these transactions as a hedge and not as a speculative investment. For example, the Fund may enter into an interest rate swap in order to protect against declines in the value of fixed income securities held by the Fund. In such an instance, the Fund may agree with a counterparty to pay a fixed rate (multiplied by a notional amount) and the counterparty to pay a floating rate multiplied by the same notional amount. If interest rates rise, resulting in a diminution in the value of the Fund, the Fund would receive payments under the swap that would offset, in whole or in part, such diminution in value; if interest rates fall, the Fund would likely lose money on the swap transaction.

Treasury Inflation-Protected Securities

The Fund may invest in Inflation-Protection Securities (“TIPSs”), a type of inflation-indexed Treasury security. TIPSs typically provide for semiannual payments of interest and a payment of principal at maturity. In general, each payment will be adjusted to take into account any inflation or deflation that occurs between the issue date of the security and the payment date based on the Consumer Price Index for All Urban Consumers (“CPI-U”).

Each semiannual payment of interest will be determined by multiplying a single fixed rate of interest by the inflation-adjusted principal amount of the security for the date of the interest payment. Thus, although the interest rate will be fixed, the amount of each interest payment will vary with changes in the principal of the security as adjusted for inflation and deflation.

TIPSs also provide for an additional payment (a “minimum guarantee payment”) at maturity if the security's inflation-adjusted principal amount for the maturity date is less than the security's principal amount at issuance. The amount of the additional payment will equal the excess of the security's principal amount at issuance over the security's inflation-adjusted principal amount for the maturity date.

U.S. Government Securities

The Fund may purchase U.S. Government securities. The types of U.S. Government obligations in which the Fund may at times invest include: (1) U.S. Treasury obligations and (2) obligations issued or guaranteed by U.S. Government agencies and instrumentalities which are supported by any of the following: (a) the full faith and credit of the U.S. Treasury, (b) the right of the issuer to borrow an amount limited to a specific line of credit from the U.S. Treasury, (c) discretionary authority of the U.S. Government agency or instrumentality, or (d) the credit of the instrumentality (examples of agencies and instrumentalities are: Federal Land Banks, Federal Housing Administration, Federal Farm Credit Bank, Farmers Home Administration, Export-Import Bank of the United States, Central Bank for Cooperatives, Federal Intermediate Credit Banks, Federal Home Loan Banks, General Services Administration, Maritime Administration, Tennessee Development Bank, Asian-American Development Bank, International Bank for Reconstruction and Development and Federal National Mortgage Association). No assurance can be given that in the future the U.S. Government will provide financial support to U.S. Government securities it is not obligated to support.

U.S. Registered Securities of Non-U.S. Issuers

The Fund may purchase publicly traded common stocks of non-U.S. corporations.

Investing in U.S. registered, dollar-denominated, securities issued by non-U.S. issuers involves some risks and considerations not typically associated with investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation taxation (which could potentially be confiscatory), adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, and potential restrictions of the flow of international capital. Non-U.S. companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

The Fund's investment in common stock of non-U.S. corporations may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, which evidence ownership of underlying securities issued by a non-U.S. corporation. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other Depositary Receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may have a non-U.S. or a U.S. issuer. Depositary Receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designated for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. The Fund may invest in unsponsored Depositary Receipts. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States, and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.

Variable Amount Master Demand Notes

The Fund may invest in variable amount master demand notes which are unsecured obligations that are redeemable upon demand and are typically unrated. These instruments are issued pursuant to written agreements between their issuers and holders. The agreements permit the holders to increase (subject to an agreed maximum) and the holders and issuers to decrease the principal amount of the notes, and specify that the rate of interest payable on the principal fluctuates according to an agreed formula. Generally, changes in interest rates will have a smaller effect on the market value of these securities than on the market value of comparable fixed income obligations. Thus, investing in these securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed income securities. There may be no active secondary market with respect to a particular variable rate instrument.

Variable and Floating Rate Securities

The Fund may invest in variable and floating rate securities. In general, variable rate securities are instruments issued or guaranteed by entities such as (1) U.S. Government, or an agency or instrumentality thereof, (2) corporations, (3) financial institutions, (4) insurance companies or (5) trusts that have a rate of interest subject to adjustment at regular intervals but less frequently than annually. A variable rate security provides for the automatic establishment of a new interest rate on set dates. Interest rates on these securities are ordinarily tied to, widely recognized market rates, which are typically set once a day. These rates may change as often as twice daily. Generally, changes in interest rates will have a smaller effect on the market value of variable and floating rate securities than on the market value of comparable fixed income obligations. Variable rate obligations will be deemed to have a maturity equal to the period remaining until the next readjustment of the interest rate.

When-Issued, Delayed Delivery and Forward Commitment Transactions

To secure an advantageous price or yield, the Fund may purchase securities on a when-issued, delayed delivery, to-be-announced (“TBA”) or forward commitment basis and may sell securities on a forward commitment or delayed delivery basis. The Fund will enter into when-issued, delayed delivery, TBA or forward commitment transactions for the purpose of acquiring securities and not for the purpose of leverage.

When purchasing a security on a when-issued, delayed delivery, TBA or forward commitment 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 NAV. When such transactions are negotiated, certain terms may be fixed at the time the commitment is made, but delivery and payment for the securities takes place at a later date. In general, the Fund does not pay for the securities until received and does not start earning interest or other income until the contractual settlement date. The Fund may take delivery of the securities or it may sell the securities before the settlement date.

At the time of delivery of the securities, the value may be more or less than the purchase or sale price. If the Fund remains substantially fully invested at a time when when-issued, delayed delivery, TBA or forward commitment purchases are outstanding, the purchases may result in a form of leverage and give rise to increased volatility of the Fund's NAV. Default by, or bankruptcy of, a counterparty to a when-issued, delayed delivery, TBA or forward commitment transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. Purchases of when-issued, delayed delivery, TBA or forward commitment securities also involve a risk of loss if the seller fails to deliver after the value of the securities has risen.

A TBA transaction involves a commitment to purchase securities sold for a fixed price where the underlying securities are announced at a future date. The seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms. For example, in a TBA mortgage-backed security transaction, the Fund and the seller would agree upon the issuer, interest rate and terms of the underlying mortgages. The seller would not identify the specific underlying mortgages until it issues the security. For this reason, in a TBA transaction, the Fund commits to purchase securities for which all specific information is not yet known at the time of the trade, particularly the exact face amount in forward commitment mortgage-backed securities transactions. The purchaser in a TBA transaction generally is subject to increased market risk and interest rate risk because the delivered securities may be less favorable than anticipated by the purchaser.

The Fund may also enter into a forward commitment to sell securities it owns. The use of forward commitments enables the Fund to hedge against anticipated changes in interest rates and prices. In a forward sale, the Fund does not participate in gains or losses on the security occurring after the commitment date. Forward commitments to sell securities also involve a risk of loss if the seller fails to take delivery after the value of the securities has declined. Forward commitment transactions involve additional risks similar to those associated with investments in options and futures contracts.

Rule amendments recently finalized by the Financial Industry Regulatory Authority, Inc. (“FINRA”) will impose, effective May 22, 2024, mandatory margin requirements for “Covered Agency Transactions,” which include TBA Transactions, certain transactions in pass-through mortgage-backed securities or small-business administration-backed asset-backed securities and transactions in CMOs, in each case where such transactions have delayed contractual settlement dates of a specified period. There are limited exceptions to these margin requirements. Covered Agency Transactions historically have not been required to be collateralized. The collateralization of Covered Agency Transactions is intended to mitigate counterparty credit risk between trade and settlement, but could increase the cost of such transactions and impose added operational complexity.

Zero-Coupon Securities

The Fund may invest in zero-coupon securities. Zero-coupon securities are notes, bonds and debentures that: (1) do not pay current interest and are issued at a substantial discount from par value; (2) have been stripped of their unmatured interest coupons and receipts; or (3) pay no interest until a stated date one or more years into the future. These securities also include certificates representing interests in such stripped coupons and receipts. Generally, changes in interest rates will have a greater impact on the market value of a zero-coupon security than on the market value of the comparable securities that pay interest periodically during the life of the instrument. In the case of any zero-coupon debt obligations with a fixed maturity date of more than one year from the date of issuance that are treated as issued originally at a discount, the Fund (or a Portfolio or Underlying Fund, as applicable) will be required to accrue original issue discount (“OID”) for U.S. federal income tax purposes and may as a result be required to pay out as an income distribution an amount which is greater than the total amount of cash interest the Fund actually received. To generate sufficient cash to make the requisite distributions to maintain its qualification for treatment as a RIC, the Fund (or a Portfolio or Underlying Fund, as applicable) may be required to sell investments, including at a time when it may not be advantageous to do so.

Privately-issued stripped securities are not themselves guaranteed by the U.S. Government, but the future payment of principal or interest on U.S. Treasury obligations which they represent is so guaranteed.

Master/Feeder Structure

The Fund may in the future determine to become a “feeder” fund that invests all of its assets in another open-end investment company (a “master fund”) that has substantially similar investment strategies as the Fund. This structure is sometimes called a “master/feeder” structure.

Fundamental Investment Restrictions

The Trust has adopted the following fundamental investment restrictions with respect to the Fund, which may not be changed without the affirmative vote of a “majority of the outstanding voting securities” of the Fund, which is defined in the 1940 Act to mean the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund and (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are present at the meeting in person or by proxy.

The Fund may borrow money and issue senior securities to the extent consistent with applicable law from time to time.

The Fund may make loans, including to affiliated investment companies, to the extent consistent with applicable law from time to time.

The Fund may purchase or sell commodities to the extent consistent with applicable law from time to time.

The Fund may purchase, sell or hold real estate to the extent consistent with applicable law from time to time.

The Fund may underwrite securities to the extent consistent with applicable law from time to time.

The Fund may not purchase any security if, as a result, 25% or more of the Fund's total assets (taken at current value) would be invested in a particular industry (for purposes of this restriction, investment companies are not considered to constitute a particular industry or group of industries), except as is consistent with applicable law from time to time and as follows: the Fund is permitted to invest without limit in “government securities” (as defined in the 1940 Act) and tax-exempt securities issued by a U.S. territory or possession, a state or local government, or a political subdivision of any of the foregoing.

For purposes of the above investment limitation number 6, in the case of a tax-exempt bond issued by a non-governmental user, where the tax-exempt bond is backed only by the assets and revenues of the non-governmental user, then such non-governmental user would be deemed to be the sole issuer. For the Fund, all percentage limitations (except the limitation to borrowings) on investments will apply at the time of the making of an investment and shall not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of such investment. Except for the investment restrictions expressly identified as fundamental, or to the extent designated as such in the Prospectus with respect to the Fund, the other investment policies described in this SAI or in the Prospectus are not fundamental and may be changed by approval of the Trustees without shareholder approval.

Names Rule Policy

To the extent the Fund is subject to Rule 35d-1 under the 1940 Act, the Fund has an investment policy, described in the Fund's prospectus, to, under normal circumstances, invest at least 80% of its assets in the particular types of investments suggested by the Fund's name (a “Name Policy”). “Assets” for the purposes of a Name Policy are net assets plus the amount of any borrowings for investment purposes. The percentage limitation applies at the time of purchase of an investment. The Fund's Name Policy may be changed by the Board of Trustees without shareholder approval. However, to the extent required by SEC regulations, shareholders will be provided with at least sixty (60) days' notice prior to any change in the Fund's Name Policy.

Additional Information

Fundamental Investment Restrictions (1) through (5), as numbered above limit the Fund's ability to engage in certain investment practices and purchase securities or other instruments to the extent consistent with applicable law as that law changes from time to time. Applicable law includes the 1940 Act, the rules or regulations thereunder and applicable orders of the SEC as are currently in place. In addition, interpretations and guidance provided by the SEC staff may be taken into account, where deemed appropriate by the Fund, to determine if an investment practice or the purchase of securities or other instruments is permitted by applicable law. As such, the effects of these limitations will change as the statute, rules, regulations or orders (or, if applicable, interpretations) change, and no shareholder vote will be required or sought when such changes permit or require a resulting change in practice.

Additional Strategy Information

At least [ ]% of the Fund's assets will be invested in underlying equity funds that each invest at least [ ]% of their respective assets in public equity securities included in such underlying equity fund's index, and at least [ ]% of the Fund's assets will be invested in underlying government securities index funds that each invest at least [80]% of their respective assets in government securities included in such underlying government fund's index.

Disclosure of Portfolio Holdings

Introduction

The policies set forth below to be followed by State Street and SSGA FM (collectively, the “Service Providers”) for the disclosure of information about the portfolio holdings of SSGA Funds, State Street Master Funds, and State Street Institutional Investment Trust (each, a “Trust”). These disclosure policies are intended to ensure compliance by the Service Providers and the Trust with applicable regulations of the federal securities laws, including the 1940 Act and the Investment Advisers Act of 1940, as amended. The Board of Trustees must approve all material amendments to the policy.

General Policy

It is the policy of the Service Providers to protect the confidentiality of client holdings and prevent the selective disclosure of non-public information concerning the Trust.

No information concerning the portfolio holdings of the Trust may be disclosed to any party (including shareholders) except as provided below. The Service Providers are not permitted to receive compensation or other consideration in connection with disclosing information about the Fund's portfolio to third-parties. In order to address potential conflicts between the interest of Fund shareholders, on the one hand, and those of the Service Providers or any affiliated person of those entities or of the Fund, on the other hand, the Fund's policies require that non-public disclosures of information regarding the Fund's portfolio may be made only if there is a legitimate business purpose consistent with fiduciary duties to all shareholders of the Fund.

The Board of Trustees exercises continuing oversight over the disclosure of the Fund's holdings by (i) overseeing the implementation and enforcement of the portfolio holding disclosure policy, Codes of Ethics and other relevant policies of the Fund and its Service Providers by the Trust's Chief Compliance Officer (“CCO”), and (ii) considering reports and recommendations by the Trust's CCO concerning any material compliance matters (as defined in Rule 38a-1 under the 1940 Act). The Board reserves the right to amend the policy at any time without prior notice in its sole discretion.

Publicly Available Information. Any party may disclose portfolio holdings information after the holdings are publicly available.

Disclosure of the complete holdings of the Fund is required to be made quarterly within 60 days of the end of the Fund's fiscal quarter in the Annual Report and Semi-Annual Report to Fund shareholders and in the monthly holdings report on Form N-PORT, with every third month made available to the public by the SEC 60 days after the end of the Portfolios' fiscal quarter. You can find SEC filings on the SEC's website, www.sec.gov. Information about the Fund's 10 largest holdings generally is posted on the Fund's website at SSGA.com, within 30 days following the end of each month. The Fund will also make complete portfolio holdings available generally no later than 60 calendar days after the end of the Fund's fiscal quarter or subsequent to periodic portfolio holdings disclosure in the Fund's filings with the SEC or on their website.

Press Interviews, Brokers and Other Discussions

Portfolio managers and other senior officers or spokespersons of the Service Providers or the Trust may disclose or confirm the ownership of any individual portfolio holding position to reporters, brokers, shareholders, consultants or other interested persons only if such information has been previously publicly disclosed in accordance with these disclosure policies. For example, a portfolio manager discussing the Trust may indicate that he owns XYZ Company for the Trust only if the Trust's ownership of such company has previously been publicly disclosed.

Trading Desk Reports

State Street Global Advisors' (“SSGA”) trading desk may periodically distribute lists of investments held by its clients (including the Trust) for general analytical research purposes. In no case may such lists identify individual clients or individual client position sizes. Furthermore, in the case of equity securities, such lists shall not show aggregate client position sizes.

Miscellaneous

Confidentiality Agreement. No non-public disclosure of the Fund's portfolio holdings will be made to any party unless such party has signed a written Confidentiality Agreement. For purposes of the disclosure policies, any Confidentiality Agreement must be in a form and substance acceptable to, and approved by, the Trust's officers.

Evaluation Service Providers. There are numerous mutual fund evaluation services (such as Morningstar, Inc. and Broadridge Financial Solutions, Inc., formerly Lipper, Inc.) and due diligence departments of broker-dealers and wirehouses that regularly analyze the portfolio holdings of mutual funds in order to monitor and report on various attributes. These services and departments then distribute the results of their analysis to the public, paid subscribers and/or in-house brokers. In order to facilitate the review of the Trust by these services and departments, the Trust may distribute (or authorize the Service Providers and the Trust's custodian or fund accountants to distribute) month-end portfolio holdings to such services and departments only if such entity has executed a confidentiality agreement.

Additional Restrictions. Notwithstanding anything herein to the contrary, the Board of Trustees, State Street and SSGA FM may, on a case-by-case basis, impose additional restrictions on the dissemination of portfolio information beyond those found in these disclosure policies.

Waivers of Restrictions. These disclosure policies may not be waived, or exceptions made, without the consent of the Trust's officers. All waivers and exceptions involving the Trust will be disclosed to the Board of Trustees no later than its next regularly scheduled quarterly meeting.

Disclosures Required by Law. Nothing contained herein is intended to prevent the disclosure of portfolio holdings information as may be required by applicable law. For example, SSGA FM, State Street, the Trust or any of its affiliates or service providers may file any report required by applicable law (such as Schedules 13D, 13G and 13F or Form N-MFP), respond to requests from regulators and comply with valid subpoenas.

Management of the Trust and State Street Master Funds

The Board of Trustees is responsible for overseeing generally the management, activities and affairs of the Fund and has approved contracts with various organizations to provide, among other services, day-to-day management required by the Trust (see the section called “Investment Advisory and Other Services”). The Board has engaged the Adviser to manage the Fund on a day-to day basis. The Board is responsible for overseeing the Adviser and other service providers in the operation of the Trust in accordance with the provisions of the 1940 Act, applicable Massachusetts law and regulation, other applicable laws and regulations, and the Amended and Restated Declaration of Trust. The Trustees listed below are also Trustees of SSGA Funds, the State Street Master Funds and the State Street Navigator Securities Lending Trust (the “Navigator Trust”), State Street Institutional Funds, State Street Variable Insurance Series Funds, Inc., Elfun Diversified Fund, Elfun Government Money Market Fund, Elfun Tax-Exempt Income Fund, Elfun Income Fund, Elfun International

Equity Fund and Elfun Trusts (collectively, the “Elfun Funds”), and their respective series.

Standing Committees

The Board of Trustees has established various committees to facilitate the timely and efficient consideration of various matters of importance to Independent Trustees, the Trust, and the Trust's shareholders and to facilitate compliance with legal and regulatory requirements. Currently, the Board has created an Audit Committee, Governance Committee, Valuation Committee, Nominating Committee and Qualified Legal Compliance Committee (the “QLCC”).

The Audit Committee is composed of all of the Independent Trustees. The Audit Committee meets twice a year, or more often as required, in conjunction with meetings of the Board of Trustees. The Audit Committee oversees and monitors the Trust's internal accounting and control structure, its auditing function and its financial reporting process. The Audit Committee is responsible for selecting and retaining the independent accountants for the Trust. The Audit Committee is

responsible for approving the audit plans, fees and other material arrangements in respect of the engagement of the independent accountants, including non-audit services performed. The Audit Committee reviews the qualifications of the independent accountant's key personnel involved in the foregoing activities and monitors the independent accountant's independence. During the fiscal year ended December 31, 2023, the Audit Committee held four meetings.

Each of the Governance Committee and the Nominating Committee is composed of all the Independent Trustees. The primary functions of the Governance Committee and the Nominating Committee are to review and evaluate the composition and performance of the Board; make nominations for membership on the Board and committees; review the responsibilities of each committee; and review governance procedures, compensation of Independent Trustees, and independence of outside counsel to the Trustees. The Nominating Committee will consider nominees to the Board recommended by shareholders. Recommendations should be submitted in accordance with the procedures set forth in the Nominating Committee Charter and should be submitted in writing to the Trust, to the attention of the Trust's Secretary, at the address of the principal executive offices of the Trust. Shareholder recommendations must be delivered to, or mailed and received at, the principal executive offices of the Trust not less than sixty (60) calendar days nor more than ninety (90) calendar days prior to the date of the Board or shareholder meeting at which the nominee candidate would be considered for election. The Governance Committee performs an annual self-evaluation of Board members. During the fiscal year ended December 31, 2023, the Governance Committee and Nominating Committee held three combined meetings.

The Valuation Committee is composed of all the Independent Trustees. The Valuation Committee's primary purpose is to review the actions and recommendations of the Adviser's Oversight Committee no less often than quarterly. The Trust has established procedures and guidelines for valuing portfolio securities and making fair value determinations from time to time through the Valuation Committee, with the assistance of the Oversight Committee, State Street and SSGA FM. During the fiscal year ended December 31, 2023, the Valuation Committee held four meetings.

The QLCC is composed of all the Independent Trustees. The primary functions of the QLCC are to receive quarterly reports from the CCO; to oversee generally the Trust's responses to regulatory inquiries; and to investigate matters referred to it by the Chief Legal Officer and make recommendations to the Board regarding the implementation of an appropriate response to evidence of a material violation of the securities laws or breach of fiduciary duty or similar violation by the Trust, its officers or the Trustees. During the fiscal year ended December 31, 2023, the QLCC held four meetings.

Leadership Structure and Risk Management Oversight

The Board has chosen to select different individuals as Chairperson of the Board of the Trust, as Chairperson and Vice-Chairperson of the Committees of the Board, and as President of the Trust. Currently, Mr. Riley, an Independent Trustee, serves as Chairperson of the Board, Ms. Rapaccioli serves as Chairperson of the Audit Committee, Mr. Costantino serves as Chairperson of the QLCC, Mr. Jessee serves as Chairperson of the Valuation Committee, and Mr. Pereira serves as Chairperson of each of the Governance Committee and Nominating Committee.

Ms. McLaughlin serves as Vice-Chairperson of the Audit Committee and Vice-Chairperson of the QLCC, Mr. Swanson serves as Vice-Chairperson of the Valuation Committee, and Ms. Rapaccioli serves as Vice-Chairperson of each of the Governance Committee and Nominating Committee. Ms. Carpenter, who is an employee of the Adviser, serves as President of the Trust. The Board believes that this leadership structure is appropriate. Ms. Carpenter is available to provide the Board with insight regarding the Trust's day-to-day management when requested, while Mr. Riley provides an independent perspective on the Trust's overall operation and Ms. Rapaccioli provides a specialized perspective on audit matters.

The Board has delegated management of the Trust to service providers who are responsible for the day-to-day management of risks applicable to the Trust. The Board oversees risk management for the Trust in several ways. The Board receives regular reports from both the CCO and administrator for the Trust, detailing the results of the Trust's compliance with its Board-adopted policies and procedures, the investment policies and limitations of the Fund, and applicable provisions of the federal securities laws and the Code. As needed, the Adviser discusses management issues regarding the Trust with the Board, soliciting the Board's input on many aspects of management, including potential risks to the Fund. The Board's Audit Committee also receives reports on various aspects of risk that might affect the Trust and offers advice to management, as appropriate. The Trustees also meet in executive session with the independent counsel to the Independent Trustees, the independent registered public accounting firm, counsel to the Trust, the CCO and representatives of management, as needed. Through these regular reports and interactions, the Board oversees the risk management parameters for the Trust, which are effected on a day-to-day basis by service providers to the Trust.

As of December 31, 2023 none of the Independent Trustees or their immediate family members had any ownership of securities of the Adviser, State Street Global Advisors Funds Distributors, LLC (“SSGA FD” or the “Distributor”), the Trust's distributor, or any person directly or indirectly controlling, controlled by or under common control with the Adviser or SSGA FD.

Trustee Compensation

Independent Trustees are compensated on a calendar year basis.

As of January 1, 2024, except as noted below, each Independent Trustee will receive for his or her services to the State Street Master Funds, the Trust, SSGA Funds, the Elfun Funds, Navigator Trust, State Street Institutional Funds and State Street Variable Insurance Series Funds, Inc.

The Chairperson of the Board receives an additional $100,000 annual retainer. As of January 1, 2023, the total annual compensation paid to the Independent Trustees (other than telephonic and special meeting fees) will be allocated to each Fund Entity as follows: a fixed amount of $21,000 is allocated to each Fund Entity or, if applicable, each series thereof; and the remainder will be allocated among the Fund Entities or, if applicable, each series thereof based on relative net assets excluding, however, any feeder fund that invests in a master fund that is a Fund Entity or series thereof. The Independent Trustees are reimbursed for travel and other out-of-pocket expenses in connection with meeting attendance. As of the date of this SAI, the Trustees were not paid pension or retirement benefits as part of the Trust's expenses.

Proxy Voting Procedures

The Board has delegated to the Adviser the responsibility to vote proxies on securities held by the Fund, subject to certain exceptions. The Board has retained authority to vote proxies for certain bank and bank holding company securities (“Bank Securities”) that may be held by the Fund from time to time. The Board has adopted the Institutional Shareholder Services, Inc.'s (“ISS”) benchmark proxy voting policy with respect to voting such Bank Securities' proxies. The Board has retained this authority in order to permit the Adviser to utilize exemptions from limitations arising under the Bank Holding Company Act of 1956, as amended, that might otherwise prevent the Adviser from investing the Fund's assets in Bank Securities. A copy of the Trust's proxy voting procedures is attached to this SAI as Appendix B, a copy of the Adviser's proxy voting procedures is attached to this SAI as Appendix C, and a copy of ISS' benchmark proxy voting procedures is attached to this SAI as Appendix D. Information regarding how the Fund voted proxies relating to its portfolio securities during the most recent twelve-month period ended June 30 is available: (1) without charge by calling 1-866-787-2257; (2) on the Fund's website at https://www.ssga.com/us/en/intermediary/ic; and (3) on the SEC's website at https://www.sec.gov.

Control Persons and Principal Holders of Securities

The Fund had not commenced operations prior to the date of this SAI and therefore did not have any beneficial owners that owned greater than 5% of the outstanding voting securities as of the date of this SAI.

The Trustees and Officers of the Trust, as a group, own less than 1% of the Trust's voting securities as of the date of this SAI.

Investment Advisory and Other Services

Investment Advisory Agreement

SSGA FM is responsible for the investment management of the Fund pursuant to the Amended and Restated Investment Advisory Agreement dated November 17, 2015, as amended from time to time (the “Advisory Agreement”), by and between the Adviser and the Trust. The Adviser is a wholly-owned subsidiary of State Street Global Advisors, Inc., which itself is a wholly-owned subsidiary of State Street Corporation, a publicly held financial holding company. State Street is a wholly-owned subsidiary of State Street Corporation.

For the services provided under the Advisory Agreement, the Fund pays the Adviser a fee at an annual rate of 0.05% of the Fund's average daily net assets.

The Advisory Agreement provides for an initial term of two years and thereafter will continue from year to year provided that such continuance is specifically approved at least annually by (a) the Trustees or by the vote of a majority of the outstanding voting securities of the Fund, and (b) vote of a majority of the Independent Trustees, cast in person at a meeting called for the purpose of voting on such approval. The Advisory Agreement may be terminated by the Adviser or the Trust without penalty upon sixty days' notice and will terminate automatically upon its assignment.

The Adviser and its affiliates may have deposit, loan and other commercial banking relationships with the issuers of obligations that may be purchased on behalf of the Fund, including outstanding loans to such issuers that could be repaid in whole or in part with the proceeds of securities so purchased. Such affiliates deal, trade and invest for their own accounts in such obligations and are among the leading dealers of various types of such obligations. The Adviser has informed the Fund that, in making its investment decisions, it will not obtain or use material non-public information in its possession or in the possession of any of its affiliates. In making investment recommendations for the Fund, the Adviser will not inquire or take into consideration whether an issuer of securities proposed for purchase or sale by the Fund is a customer of the Adviser, its parent or its subsidiaries or affiliates and, in dealing with its customers, the Adviser, its parent, subsidiaries and affiliates will not inquire or take into consideration whether securities of such customers were held by any fund managed by the Adviser or any such affiliate.

In certain instances, there may be securities that are suitable for the Fund as well as for one or more of the Adviser's other clients. Investment decisions for the Trust and for the Adviser's other clients are made with a view to achieving their respective investment objectives. It may develop that a particular security is bought or sold for only one client even though it might be held by, or bought or sold for, other clients. Likewise, a particular security may be bought for one or more clients when one or more clients are selling that same security. Some simultaneous transactions are inevitable when several

clients receive investment advice from the same investment adviser, particularly when the same security is suitable for the investment objectives of more than one client. When two or more clients are simultaneously engaged in the purchase or sale of the same security, the securities are allocated among clients in a manner believed to be equitable to each. The Trust recognizes that in some cases this system could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, it is believed that the ability of the Fund to participate in volume transactions will produce better executions for the Fund.

The Fund had not commenced operations as of the date of this SAI and therefore did not pay fees to the Adviser for the past three fiscal years.

Total Annual Fund Operating Expense Waivers and Reimbursements. The Adviser has contractually agreed with the Trust, through [ ] to (1) waive advisory fees and/or (2) reimburse the Fund for expenses to the extent that Total Annual Fund Operating Expenses (subject to certain exclusions as described in the Fund's Prospectus) exceed [ ]% of average daily net assets on an annual basis.

Administrator

SSGA FM serves as the administrator for the Fund pursuant to an Amended and Restated Administration Agreement. Under the Amended and Restated Administration Agreement, SSGA FM is obligated to continuously provide business management services to the Trust and the Fund and will generally, subject to the general oversight of the Trustees and except as otherwise provided in the Amended and Restated Administration Agreement, manage all of the business and affairs of the Trust. The nature and amount of services provided by SSGA FM under the Amended and Restated Administration Agreement may vary as between classes of shares of the Fund, and the Fund may pay fees to SSGA FM under that Agreement at different rates in respect of its different share classes. The Fund reimburses SSGA FM for certain out-of-pocket travel expenses of the CCO and compliance team incurred on the Fund's behalf.

As consideration for SSGA FM's services as administrator with respect to the Fund, SSGA FM receives a fee at the annual rate of 0.05% of the average daily net assets attributable to each class of shares of the Fund. The fees are accrued daily at the rate of 1/365th and payable monthly on the first business day of each month.

The administration fees paid by the Fund to SSGA FM for the last three fiscal years have been omitted because the Fund had not commenced investment operations as of the date of this SAI.

SUB-ADMINISTRATOR, CUSTODY AND FUND ACCOUNTING

State Street serves as the sub-administrator for the Trust, pursuant to a sub-administration agreement dated June 1, 2015 (the “Sub-Administration Agreement”). State Street serves as the custodian for the Trust, pursuant to a custody agreement dated April 11, 2012 (the “Custody Agreement”). Under the Sub-Administration Agreement, State Street is obligated to provide certain sub-administrative services to the Trust. Under the Custody Agreement, State Street is obligated to provide certain custody services to the Trust, as well as basic portfolio recordkeeping required by the Trust for regulatory and financial reporting purposes. State Street is a wholly owned subsidiary of State Street Corporation, a publicly held financial holding company, and is affiliated with the Adviser. State Street's mailing address is State Street Financial Center, One Lincoln Street, Boston, Massachusetts 02111-2900.

State Street receives an annual fee from the Adviser (payable monthly), as consideration for sub-administration services provided to the Fund. As consideration for custody and fund accounting services, the Fund pays State Street an annual fee (payable monthly) based on the average monthly net assets of the Fund. The Fund also pays State Street transaction and service fees for these services and reimburses State Street for out-of-pocket expenses.

The sub-administration (if applicable), custodian and fund accounting fees paid by the Fund to State Street for the last three fiscal years have been omitted because the Fund had not commenced investment operations as of the date of this SAI.

Transfer Agent and Dividend Paying Agent

SS&C GIDS, Inc. serves as the Transfer and Dividend Paying Agent. SS&C GIDS, Inc. is paid for the following annual account services and activities including but not limited to: establishment and maintenance of each shareholder's account; closing an account; acceptance and processing of trade orders; preparation and transmission of payments for dividends and distributions declared by the Fund; customer service support including receipt of correspondence and responding to shareholder and financial intermediary inquiries; investigation services; tax related support; financial intermediary commission and fee payment processing; and charges related to compliance and regulatory services.

Portfolio fees are allocated to the Fund based on the average NAV of the Fund and are billable on a monthly basis at the rate of 1/12 of the annual fee. SS&C GIDS, Inc. is reimbursed by the Fund for supplying certain out-of-pocket expenses including confirmation statements, investor statements, banking fees, postage, forms, audio response, telephone, records retention, customized programming/enhancements, reports, transcripts, microfilm, microfiche, and expenses incurred at the specific direction of the Fund. SS&C GIDS, Inc. principal business address is 2000 Crown Colony Drive, Quincy, MA 02169.

Securities Lending

The Fund's Board has approved the Fund's participation in a securities lending program. Under the securities lending program, the Fund has retained State Street to serve as the securities lending agent.

For the fiscal year ended December 31, 2023, the income earned by the Fund as well as the fees and/or compensation paid by the Fund (in dollars) pursuant to the Master Amended and Restated Securities Lending Authorization Agreement among SSGA Funds, State Street Institutional Investment Trust, and State Street Master Funds, each on behalf of its respective series, and State Street (the “Securities Lending Authorization Agreement”) have been omitted because the Fund had not commenced investment operations as of the date of this SAI.

State Street, acting as agent of the Fund, will provide the following services to the Fund in connection with the Fund's securities lending activities: (i) locating borrowers among an approved list of prospective borrowers; (ii) monitoring the value of loaned securities, the value of collateral received and other lending parameters; (iii) seeking additional collateral, as necessary, from borrowers; (iv) receiving and holding collateral from borrowers, and facilitating the investment and reinvestment of all or substantially all cash collateral in an investment vehicle designated by the Fund; (v) returning collateral to borrowers; (vi) facilitating substitute dividend, interest, and other distribution payments to the Fund from borrowers; (vii) negotiating the terms of each loan of securities, including but not limited to the amount of any loan premium, and monitoring the terms of securities loan agreements with prospective borrowers for consistency with the requirements of the Fund's Securities Lending Authorization Agreement; (viii) selecting securities, including amounts (percentages), to be loaned; (ix) recordkeeping and accounting servicing; and (x) arranging for return of loaned securities to the Fund in accordance with the terms of the Securities Lending Authorization Agreement.

Code of Ethics

The Adviser, SSGA FD and the Trust have each adopted a code of ethics (the Trust's code being referred to herein as the “Code of Ethics”) under Rule 17j-1 of the 1940 Act. The Code of Ethics, by relying on the codes of the underlying service providers, permits personnel of the Fund's Adviser, Distributor and officers, subject to the provisions of the relevant code of ethics, to invest in securities, including securities that may be purchased or held by the Adviser or the Trust. Under the relevant code of ethics, all employees or officers who are deemed to be access persons (persons who have interaction with funds or accounts managed by the Adviser or SSGA FD as part of their job function) must pre-clear personal securities transactions. Each code of ethics is designed to ensure that employees conduct their personal securities transactions in a manner that does not create an actual or potential conflict of interest to the business or fiduciary responsibilities of the Trust's service providers or officers. In addition, the Code of Ethics establishes standards prohibiting the trading in or recommending of securities based on material, nonpublic information or the divulgence of such information to others.

Distributor

SSGA FD serves as the distributor of the Fund. SSGA FD is an indirect wholly-owned subsidiary of State Street Corporation. SSGA FD's mailing address is One Iron Street, Boston, MA 02210.

Distribution Plan

To compensate SSGA FD for the services it provides and for the expenses it bears in connection with the distribution of shares of the Fund, SSGA FD will be entitled to receive any front-end sales load applicable to the sale of shares of the Fund. The Fund may make payments from the assets attributable to certain classes of its shares to SSGA FD under a distribution plan adopted pursuant to Rule 12b-1 under the 1940 Act (the “Distribution Plan”). The Distribution Plan is a compensation plan that provides for payments at annual rates (based on average daily net assets) described below. Because Rule 12b-1 Fees are paid on an ongoing basis, they will increase the cost of your investment and may cost you more than paying other types of sales loads. The principal business address of SSGA FD is One Iron Street, Boston, MA 02210.

The Board, including all of the Trustees who are not interested persons (as defined in the 1940 Act) of the Trust (the “Independent Trustees”) and who have no direct or indirect financial interest in the Distribution Plan or any related agreements, (the “Qualified Distribution Plan Trustees”) approved the Distribution Plan. The Distribution Plan will continue in effect with respect to a class of shares of the Fund only if such continuance is specifically approved at least annually by a vote of both a majority of the Board of Trustees of the Trust and a majority of the Qualified Distribution Plan Trustees. The Distribution Plan may not be amended to increase materially the amount of the Fund's permitted expenses thereunder without the approval of a majority of the outstanding shares of the affected share class and may not be materially amended in any case without a vote of the majority of both the Trustees and the Qualified Distribution Plan Trustees. As of December 31, 2023, none of the Independent Trustees had a direct or indirect financial interest in the operation of the Distribution Plan. The Distribution Plan calls for payments at an annual rate (based on the Fund's average net assets) as follows:

Class	Annual 12b-1 Fee
Class I	____ %
Class K	____ %
Class R3	____ %

The Distribution Plan may benefit the Fund by increasing sales of shares and reducing redemptions of shares, resulting potentially, for example, in economies of scale and more predictable flows of cash into and out of the Fund. Because Rule 12b-1 fees are paid out of the Fund's assets, all shareholders share in that expense; however, because shareholders hold their shares through varying arrangements (for example, directly or through financial intermediaries), they may not share equally in the benefits of the Distribution Plan.

Payments to Financial Intermediaries

Financial intermediaries are firms that, for compensation, sell shares of mutual funds, including the Fund, and/or provide certain administrative and account maintenance services to mutual fund shareholders. Financial intermediaries may include, among others, brokers, financial planners or advisors, banks, and insurance companies. In some cases, a financial intermediary may hold its clients' Fund shares in nominee or street name. Shareholder services provided by a financial intermediary may (though they will not necessarily) include, among other things: processing and mailing trade confirmations, periodic statements, prospectuses, annual reports, semi-annual reports, shareholder notices, and other SEC-required communications; capturing and processing tax data; issuing and mailing dividend checks to shareholders who have selected cash distributions; preparing record date shareholder lists for proxy solicitations; collecting and posting distributions to shareholder accounts; and establishing and maintaining systematic withdrawals and automated investment plans and shareholder account registrations. Some portion of SSGA FD's payments to financial intermediaries will be made out of amounts received by SSGA FD under the Fund's Distribution Plan. In addition, the Fund may reimburse SSGA FD for payments SSGA FD makes to financial intermediaries that provide recordkeeping, shareholder servicing, sub-transfer agency, administrative and/or account maintenance services (collectively, “servicing”). The amount of the reimbursement for servicing compensation and the manner in which it is calculated are reviewed by the Trustees periodically.

The compensation paid by SSGA FD to a financial intermediary may be paid continually over time, during the period when the intermediary's clients hold investments in the Fund. The compensation to financial intermediaries may include networking fees and account-based fees. The amount of continuing compensation paid by SSGA FD to different financial intermediaries varies. In the case of most financial intermediaries, compensation for servicing in excess of any amount covered by payments under a Distribution Plan is generally paid at an annual rate of 0.10% – 0.20% of the aggregate average daily NAV of Fund shares held by that financial intermediary's customers, although in some cases the compensation may be paid at higher annual rates (which may, but will not necessarily, reflect enhanced or additional services provided by the financial intermediary). SSGA FD and its affiliates (including SSGA FM), at their own expense and out of their own assets, may also provide compensation to financial intermediaries in connection with sales of the Fund's shares or the servicing of shareholders or shareholder accounts by financial intermediaries. Such compensation may include, but is not limited to, ongoing payments, financial assistance to financial intermediaries in connection with conferences, sales, or training programs for their employees, seminars for the public, advertising or sales campaigns, or other financial intermediary-sponsored special events. In some instances, this compensation may be made available only to certain financial intermediaries whose representatives have sold or are expected to sell significant amounts of shares. Financial intermediaries may not use sales of the Fund's shares to qualify for this compensation to the extent prohibited by the laws or rules of any state or any self-regulatory agency, such as FINRA. The level of payments made to a financial

intermediary in any given year will vary and, in the case of most financial intermediaries, will not exceed 0.20% of the value of assets attributable to the financial intermediary invested in shares of funds in the SSGA FM-fund complex. In certain cases, the payments described in the preceding sentence are subject to minimum payment levels.

If payments to financial intermediaries by the distributor or adviser for a particular mutual fund complex exceed payments by other mutual fund complexes, your financial advisor and the financial intermediary employing him or her may have an incentive to recommend that fund complex over others. Please speak with your financial advisor to learn more about the total amounts paid to your financial advisor and his or her firm by SSGA FD and its affiliates, and by sponsors of other mutual funds he or she may recommend to you. You should also consult disclosures made by your financial intermediary at the time of purchase.

Because the Fund pays distribution, service and other fees for the sale of their shares and for services provided to shareholders out of the Fund's assets on an ongoing basis, over time those fees will increase the cost of an investment in the Fund.

The Fund may pay distribution fees, service fees and other amounts described above at a time when shares of the Fund are not being actively promoted to new investors generally, or when shares of that Fund are unavailable for purchase.

Set forth below is a list of those financial intermediaries to which SSGA FD (and its affiliates) expects, as of April 30, 2024, to pay compensation in the manner described in this “Payments to Financial Intermediaries” section. This list may change over time. Please contact your financial intermediary to determine whether it or its affiliate currently may be receiving such compensation and to obtain further information regarding any such compensation.

Portfolio Managers

The Adviser manages the Fund using a team of investment professionals. The following table lists the number and types of accounts managed by each of the key professionals involved in the day-to-day portfolio management for the Fund and assets under management in those accounts. The total number of accounts and assets have been allocated to each respective manager. Therefore, some accounts and assets have been counted twice.

Portfolio Manager	Registered Investment Company Accounts	Assets Managed (billions)	Other Pooled Investment Vehicle Accounts	Assets Managed (billions)	Other Accounts	Assets Managed (billions)	Total Assets Managed (billions)
Michael Narkiewicz	[]	$[]	[]	$[]	[]	$[]	$[]
Seamus Quinn	[]	$[]	[]	$[]	[]	$[]	$[]

The Fund had not commenced operations prior to the date of this SAI and therefore the portfolio managers did not beneficially own any Shares.

A portfolio manager that has responsibility for managing more than one account may be subject to potential conflicts of interest because he or she is responsible for other accounts in addition to the Fund. Those conflicts could include preferential treatment of one account over others in terms of: (a) the portfolio manager's execution of different investment strategies for various accounts; or (b) the allocation of resources or of investment opportunities.

Portfolio managers may manage numerous accounts for multiple clients. These accounts may include registered investment companies, other types of pooled accounts (e.g., collective investment funds), and separate accounts (i.e., accounts managed on behalf of individuals or public or private institutions). Portfolio managers make investment decisions for each account based on the investment objectives and policies and other relevant investment considerations applicable to that portfolio. A potential conflict of interest may arise as a result of a portfolio manager's responsibility for multiple accounts with similar investment guidelines. Under these circumstances, a potential investment may be suitable for more

than one of the portfolio manager's accounts, but the quantity of the investment available for purchase is less than the aggregate amount the accounts would ideally allocate to the opportunity. Similar conflicts may arise when multiple accounts seek to dispose of the same investment. The portfolio managers may also manage accounts whose objectives and policies differ from that of the Fund. These differences may be such that under certain circumstances, trading activity appropriate for one account managed by the portfolio manager may have adverse consequences for another account managed by the portfolio manager. For example, an account may sell a significant position in a security, which could cause the market price of that security to decrease, while the Fund maintained its position in that security.

A potential conflict may arise when the portfolio managers are responsible for accounts that have different advisory fees—the difference in fees could create an incentive for the portfolio manager to favor one account over another, for example, in terms of access to investment opportunities. This conflict may be heightened if an account is subject to a performance-based fee, as applicable. Another potential conflict may arise when the portfolio manager has a personal investment in one or more accounts that participate in transactions with other accounts. His or her personal investment(s) may create an incentive for the portfolio manager to favor one account over another. The Adviser has adopted policies and procedures reasonably designed to address these potential material conflicts. For instance, portfolio managers are normally responsible for all accounts within a certain investment discipline and do not, absent special circumstances, differentiate among the various accounts when allocating resources. Additionally, the Adviser and its advisory affiliates have processes and procedures for allocating investment opportunities among portfolios that are designed to provide a fair and equitable allocation. With respect to conflicts arising from personal investments, all employees, including portfolio managers, must comply with personal trading controls established by each of the Adviser's and Trust's Code of Ethics.

SSGA's culture is complemented and reinforced by a total rewards strategy that is based on a pay for performance philosophy which seeks to offer a competitive pay mix of base salary, benefits, cash incentives and deferred compensation.

Salary is based on a number of factors, including external benchmarking data and market trends, and performance both at the business and individual level. SSGA's Global Human Resources department regularly participates in compensation surveys in order to provide SSGA with market-based compensation information that helps support individual pay decisions.

Additionally, subject to State Street and SSGA business results, an incentive pool is allocated to SSGA to reward its employees. The size of the incentive pool for most business units is based on the firm's overall profitability and other factors, including performance against risk-related goals. For most SSGA investment teams, SSGA recognizes and rewards performance by linking annual incentive decisions for investment teams to the firm's or business unit's profitability and business unit investment performance over a multi-year period.

Incentive pool funding for most active investment teams is driven in part by the post-tax investment performance of fund(s) managed by the team versus the return levels of the benchmark index(es) of the fund(s) on a one-, three- and, in some cases, five-year basis. For most active investment teams, a material portion of incentive compensation for senior staff is deferred over a four-year period into the SSGA Long-Term Incentive (“SSGA LTI”) program. For these teams, The SSGA LTI program indexes the performance of these deferred awards against the post-tax investment performance of fund(s) managed by the team. This is intended to align our investment team's compensation with client interests, both through annual incentive compensation awards and through the long-term value of deferred awards in the SSGA LTI program.

For the index equity investment team, incentive pool funding is driven in part by the post-tax 1 and 3-year tracking error of the funds managed by the team against the benchmark indexes of the funds.

The discretionary allocation of the incentive pool to the business units within SSGA is influenced by market-based compensation data, as well as the overall performance of each business unit. Individual compensation decisions are made by the employee's manager, in conjunction with the senior management of the employee's business unit. These decisions are based on the overall performance of the employee and, as mentioned above, on the performance of the firm and business unit. Depending on the job level, a portion of the annual incentive may be awarded in deferred compensation, which may include cash and/or Deferred Stock Awards (State Street stock), which typically vest over a four-year period. This helps to retain staff and further aligns SSGA employees' interests with SSGA clients' and shareholders' long-term interests.

SSGA recognizes and rewards outstanding performance by:

•Promoting employee ownership to connect employees directly to the company's success.

•Using rewards to reinforce mission, vision, values and business strategy.

•Seeking to recognize and preserve the firm's unique culture and team orientation.

•Providing all employees the opportunity to share in the success of SSGA.

Brokerage Allocation and Other Practices

All portfolio transactions are placed on behalf of the Fund by the Adviser. Purchases and sales of securities on a securities exchange are affected through brokers who charge a commission for their services. Ordinarily commissions are not charged on over-the-counter orders (e.g., fixed income securities) because the Fund pays a spread which is included in the cost of the security and represents the difference between the dealer's quoted price at which it is willing to sell the security and the dealer's quoted price at which it is willing to buy the security. When the Fund executes an over-the-counter order with an electronic communications network or an alternative trading system, a commission is charged by such electronic communications networks and alternative trading systems as they execute such orders on an agency basis. Securities may be purchased from underwriters at prices that include underwriting fees.

In placing a portfolio transaction, the Adviser seeks to achieve best execution. The Adviser's duty to seek best execution requires the Adviser to take reasonable steps to obtain for the client as favorable an overall result as possible for Fund portfolio transactions under the circumstances, taking into account various factors that are relevant to the particular transaction.

The Adviser refers to and selects from the list of approved trading counterparties maintained by the Adviser's Credit Risk Management team. In selecting a trading counterparty for a particular trade, the Adviser seeks to weigh relevant factors including, but not limited to the following:

•Prompt and reliable execution;

•The competitiveness of commission rates and spreads, if applicable;

•The financial strength, stability and/or reputation of the trading counterparty;

•The willingness and ability of the executing trading counterparty to execute transactions (and commit capital) of size in liquid and illiquid markets without disrupting the market for the security;

•Local laws, regulations or restrictions;

•The ability of the trading counterparty to maintain confidentiality;

•The availability and capability of execution venues, including electronic communications networks for trading and execution management systems made available to Adviser;

•Market share;

•Liquidity;

•Price;

•Execution related costs;

•History of execution of orders;

•Likelihood of execution and settlement;

•Order size and nature;

•Clearance and settlement capabilities, especially in high volatility market environments;

•Availability of lendable securities;

•Sophistication of the trading counterparty's trading capabilities and infrastructure/facilities;

•The operational efficiency with which transactions are processed and cleared, taking into account the order size and complexity;

•Speed and responsiveness to the Adviser;

•Access to secondary markets;

•Counterparty exposure; and

•Depending upon the circumstances, the Adviser may take other relevant factors into account if the Adviser believes that these are important in taking all sufficient steps to obtain the best possible result for execution of the order.

In selecting a trading counterparty, the price of the transaction and costs related to the execution of the transaction typically merit a high relative importance, depending on the circumstances. The Adviser does not necessarily select a trading counterparty based upon price and costs but may take other relevant factors into account if it believes that these are important in taking reasonable steps to obtain the best possible result for the Fund under the circumstances. Consequently, the Adviser may cause a client to pay a trading counterparty more than another trading counterparty might have charged for the same transaction in recognition of the value and quality of the brokerage services provided. The following matters may influence the relative importance that the Adviser places upon the relevant factors:

(i)

The nature and characteristics of the order or transaction. For example, size of order, market impact of order, limits, or other instructions relating to the order;

(ii)

The characteristics of the financial instrument(s) or other assets which are the subject of that order. For example, whether the order pertains to an equity, fixed income, derivatives or convertible instrument;

(iii)

The characteristics of the execution venues to which that order can be directed, if relevant. For example, availability and capabilities of electronic trading systems;

(iv)

Whether the transaction is a ‘delivery versus payment' or ‘over-the-counter' transaction. The creditworthiness of the trading counterparty, the amount of existing exposure to a trading counterparty and trading counterparty settlement capabilities may be given a higher relative importance in the case of ‘over-the-counter' transactions; and/or

(v)

Any other circumstances that the Adviser believes are relevant at the time.

The process by which trading counterparties are selected to effect transactions is designed to exclude consideration of the sales efforts conducted by broker-dealers in relation to the Fund.

The Adviser does not currently use the Fund's assets in connection with third-party soft dollar arrangements. While the Adviser does not currently use “soft” or commission dollars paid by the Fund for the purchase of third-party research, the Adviser reserves the right to do so in the future.

Securities of “Regular Broker-Dealer.” The Trust is required to identify any securities of its “regular brokers and dealers” (as such term is defined in the 1940 Act) which it may hold at the close of its most recent fiscal year. “Regular brokers or dealers” of the Trust are the ten brokers or dealers that, during the most recent fiscal year: (i) received the greatest dollar amounts of brokerage commissions from the Trust's portfolio transactions; (ii) engaged as principal in the largest dollar amounts of portfolio transactions of the Trust; or (iii) sold the largest dollar amounts of the Trust's shares.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates are likely to result in comparatively greater brokerage expenses or transaction costs. The overall reasonableness of brokerage commissions and transaction costs is evaluated by the Adviser based upon its knowledge of available information as to the general level of commissions and transaction costs paid by other institutional investors for comparable services.

The Fund had not commenced operations as of the date of this SAI and therefore did not pay brokerage commissions during the past three fiscal years.

Declaration of Trust, Capital Stock and Other Information

Capitalization

Under the Declaration of Trust, the Trustees are authorized to issue an unlimited number of shares of the Fund. Upon liquidation or dissolution of the Fund, investors are entitled to share pro rata in the Fund's net assets available for distribution to its investors. Investments in the Fund have no preference, preemptive, conversion or similar rights, except as determined by the Trustees or as set forth in the Bylaws, and are fully paid and non-assessable, except as set forth below.

Declaration of Trust

The Declaration of Trust of the Trust provides that the Trust may redeem shares of the Fund at the redemption price that would apply if the share redemption were initiated by a shareholder. It is the policy of the Trust that, except upon such conditions as may from time to time be set forth in the then current prospectus of the Trust or to facilitate the Trust's or the Fund's compliance with applicable law or regulation, the Trust would not initiate a redemption of shares unless it were to determine that failing to do so may have a substantial adverse consequence for the Fund or the Trust.

The Trust's Declaration of Trust provides that a Trustee who is not an “interested person” (as defined in the 1940 Act) of the Trust will be deemed independent and disinterested with respect to any demand made in connection with a derivative action or proceeding. It is the policy of the Trust that it will not assert that provision to preclude a shareholder from claiming that a trustee is not independent or disinterested with respect to any demand made in connection with a derivative action or proceeding; provided, however, that the foregoing policy will not prevent the Trust from asserting applicable law (including Section 2B of Chapter 182 of the Massachusetts General Laws) to preclude a shareholder from claiming that a trustee is not independent or disinterested with respect to any demand made in connection with a derivative action or proceeding.

The Trust will not deviate from the foregoing policies in a manner that adversely affects the rights of shareholders of the Fund without the approval of “a vote of a majority of the outstanding voting securities” (as defined in the 1940 Act) of the Fund.

Voting

Each investor is entitled to a vote in proportion to the number of Fund shares it owns. Shares do not have cumulative voting rights in the election of Trustees, and investors holding more than 50% of the aggregate outstanding shares in the Trust may elect all of the Trustees if they choose to do so. The Trust is not required and has no current intention to hold annual meetings of investors but the Trust will hold special meetings of shareholders when in the judgment of the Trustees it is necessary or desirable to submit matters for a shareholder vote.

Massachusetts Business Trust

Under Massachusetts law, shareholders in a Massachusetts business trust could, under certain circumstances, be held personally liable for the obligations of the trust. However, the Declaration of Trust disclaims shareholder liability for acts or obligations of the Trust and provides for indemnification out of the property of the applicable series of the Trust for any loss to which the shareholder may become subject by reason of being or having been a shareholder of that series and for reimbursement of the shareholder for all expense arising from such liability. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability should be limited to circumstances in which the series would be unable to meet its obligations.

Pricing of Shares

Multiple-class funds do not have a single share price. Rather, each class has a share price, called its NAV. The price per share for each class of the Fund is determined each business day (unless otherwise noted) at the close of the New York Stock Exchange (“NYSE”) (ordinarily 4:00 p.m. Eastern time).

Pricing of shares of the Fund does not occur on New York Stock Exchange (“NYSE”) holidays. The NYSE is open for trading every weekday except for: (a) the following holidays: New Year's Day, Martin Luther King, Jr.'s Birthday, Washington's Birthday (the third Monday in February), Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas; and (b) the preceding Friday or the subsequent Monday when one of the calendar-determined holidays falls on a Saturday or Sunday, respectively. Purchases and withdrawals will be effected at the time of determination of NAV next following the receipt of any purchase or withdrawal order which is determined to be in good order.

The Fund's securities will be valued pursuant to guidelines established by the Board of Trustees.

Taxation of the Fund

The following discussion of U.S. federal income tax consequences of an investment in the Fund is based on the Code, U.S. Treasury regulations, and other applicable authority, as of the date of this SAI. These authorities are subject to change by legislative or administrative action, possibly with retroactive effect. The following discussion is only a summary of some of the important U.S. federal income tax considerations generally applicable to investments in the Fund. There may be other tax considerations applicable to particular shareholders. Shareholders should consult their own tax advisors regarding their particular situation and the possible application of foreign, state and local tax laws.

The Fund invests in the Underlying Funds, and so substantially all of the Fund's income will result from distributions or deemed distributions, or allocations, from the Underlying Funds, as the case may be. Therefore, as applicable, references to the U.S. federal income tax treatment of the Fund, including to the assets owned and the income earned by the Fund, will be to, or will include, such treatment of the Underlying Funds, and, as applicable, the assets owned and the income earned by the Underlying Funds. See “Tax Considerations Applicable to Funds Investing in Portfolios Treated as Partnerships” and “Tax Considerations Applicable to Funds Investing in Portfolios or Underlying Funds Treated as RICs” below for further information.

Special tax rules apply to investments through defined contribution plans and other tax-qualified plans or tax-advantaged arrangements. Shareholders should consult their tax advisers to determine the suitability of shares of the Fund as an investment through such plans and arrangements and the precise effect of an investment on their particular tax situations.

Qualification as a Regulated Investment Company

The Fund intends to elect to be treated as a RIC under Subchapter M of the Code and intends each year to qualify and be eligible to be treated as such. In order to qualify for the special tax treatment accorded RICs and their shareholders, the Fund must, among other things, (a) derive at least 90% of its gross income for each taxable year from (i) dividends, interest, payments with respect to certain securities loans, gains from the sale of securities or foreign currencies, or other income (including but not limited to gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies and (ii) net income derived from interests in “qualified publicly traded partnerships” (as defined below); (b) diversify its holdings so that, at the end of each quarter of the Fund's taxable year, (i) at least 50% of the value of the Fund's total assets consists of cash and cash items, U.S. Government securities, securities of other RICs, and other securities limited in respect of any one issuer to a value not greater than 5% of the value of the Fund's total assets and no more than 10% of the outstanding voting securities of such issuer, and (ii) no more than 25% of its assets are invested, including through corporations in which the Fund owns a 20% or more voting stock interest, (x) in the securities (other than those of the U.S. Government or other RICs) of any one issuer or of two or more issuers which the Fund controls and which are engaged in the same, similar or related trades and businesses, or (y) in the securities of one or more qualified publicly traded partnerships (as defined below); and (c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid — generally taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt income, for such year.

In general, for purposes of the 90% gross income requirement described in (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized directly by the RIC. However, 100% of the net income derived from an interest in a “qualified publicly traded partnership” (a partnership (x) the interests in which are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof, and (y) that derives less than 90% of its income from the qualifying income described in section (a)(i) of the preceding paragraph), will be treated as

qualifying income. In general, such entities will be treated as partnerships for U.S. federal income tax purposes, because they meet the passive income requirement under Code section 7704(c)(2). Further, although U.S. in general the passive loss rules of the Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly traded partnership.

For purposes of the diversification test in (b) above, the term “outstanding voting securities of such issuer” will include the equity securities of a qualified publicly traded partnership. Also, for purposes of the diversification test in (b) above, the identification of the issuer (or, in some cases, issuers) of a particular investment can depend on the terms and conditions of that investment. In some cases, identification of the issuer (or issuers) is uncertain under current law, and an adverse determination or future guidance by the Internal Revenue Service (“IRS”) with respect to issuer identification for a particular type of investment may adversely affect the Fund's ability to meet the diversification test in (b) above.

If the Fund qualifies as a RIC that is accorded special tax treatment, the Fund will not be subject to U.S. federal income tax on income or gains distributed in a timely manner to its shareholders in the form of dividends (including Capital Gain Dividends, as defined below). If the Fund were to fail to meet the income, diversification or distribution test described above, the Fund could in some cases cure such failure, including by paying the Fund-level tax, paying interest or disposing of certain assets. If such Fund were ineligible to or otherwise did not cure such failure for any year, or if such Fund were otherwise to fail to qualify as a RIC accorded special tax treatment in any taxable year, the Fund would be subject to tax at the Fund level on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net tax-exempt income (if any) and net capital gains ( as defined below), would be taxable to shareholders as ordinary income. Some portions of such distributions may be eligible for the dividends-received deduction in the case of corporate shareholders and may be eligible to be treated as “qualified dividend income” in the case of shareholders taxed as individuals, provided, in both cases, the shareholder meets certain holding period and other requirements in respect of the Fund's shares (each as described below). In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before re-qualifying as a RIC that is accorded special tax treatment.

The Fund intends to distribute at least annually to its shareholders all or substantially all of its investment company taxable income (computed without regard to the dividends-paid deduction) and its net tax-exempt income (if any), and may distribute its net capital gain (that is, the excess of net long-term capital gain over net short-term capital loss, in each case determined with reference to any loss carryforwards). Any taxable income retained by the Fund will be subject to tax at the Fund level at regular corporate rates. If the Fund retains any net capital gain, it will be subject to tax at regular corporate rates on the amount retained, but it is permitted to designate the retained amount as undistributed capital gain in a timely notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their shares of such undistributed amount, and (b) will be entitled to credit their proportionate shares of the tax paid by the Fund on such undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds on a properly-filed U.S. tax return to the extent the credit exceeds such liabilities. If the Fund makes this designation, for U.S. federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal to the difference between the amount of undistributed capital gains included in the shareholder's gross income under clause (a) of the preceding sentence and the tax deemed paid by the shareholder under clause (b) of the preceding sentence. The Fund is not required to, and there can be no assurance the Fund will, make this designation if it retains all or a portion of its net capital gain in a taxable year.

In determining its net capital gain, including in connection with determining the amount available to support a Capital Gain Dividend (as defined below), its taxable income, and its earnings and profits, a RIC generally may elect to treat part or all of any post-October capital loss (defined as any net capital loss attributable to the portion, if any, of the taxable year after October 31 or, if there is no such loss, the net long-term capital loss or net short-term capital loss attributable to any such portion of the taxable year) or late-year ordinary loss (generally, the sum of its (i) net ordinary loss, if any, from the sale, exchange or other taxable disposition of property, attributable to the portion, if any, of the taxable year after October 31, and its (ii) other net ordinary loss, if any, attributable to the portion, if any, of the taxable year after December 31) as if incurred in the succeeding taxable year.

If the Fund were to fail to distribute in a calendar year at least an amount equal, in general, to the sum of 98% of its ordinary income for such year and 98.2% of its capital gain net income for the one-year period ending October 31 of such year (or November 30 or December 31, if the Fund is eligible to elect and so elects), plus any such amounts retained from the prior year, the Fund would be subject to a nondeductible 4% excise tax on the undistributed amounts. For purposes of the required excise tax distribution, a RIC's ordinary gains and losses from the sale, exchange or other taxable disposition of property that would otherwise be taken into account after October 31 of a calendar year (or November 30, if the Fund

makes the election referred to above) generally are treated as arising on January 1 of the following calendar year; in the case of the Fund with a December 31 year end that makes the election described above, no such gains or losses will be so treated. Also, for these purposes, the Fund will be treated as having distributed any amount on which it is subject to corporate income tax for the taxable year ending within the calendar year. The Fund intends generally to make distributions sufficient to avoid imposition of the excise tax, although there can be no assurance that it will be able to do so. Distributions declared by the Fund during October, November and December to shareholders of record on a date in any such month and paid by the Fund during the following January will be treated for federal tax purposes as paid by the Fund and received by shareholders on December 31 of the year in which declared.

Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against the Fund's net investment income. Instead, potentially subject to certain limitations, the Fund may carry net capital losses from any taxable year forward to subsequent taxable years to offset capital gains, if any, realized during such subsequent taxable years. Distributions from capital gains are generally made after applying any available capital loss carryforwards. Capital loss carryforwards are reduced to the extent they offset current-year net realized capital gains, whether the Fund retains or distributes such gains. The Fund may carry net capital losses forward to one or more subsequent taxable years without expiration; any such carryforward losses will retain their character as short-term or long-term. The Fund must apply such carryforwards first against gains of the same character. See the Fund's most recent annual shareholder report for the Fund's available capital loss carryovers as of the end of its most recently ended fiscal year.

Taxation of Distributions Received by Shareholders

For U.S. federal income tax purposes, distributions of investment income are generally taxable to shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long the Fund owned (or is deemed to have owned) the investments that generated them, rather than how long a shareholder has owned his or her Fund shares. In general, the Fund will recognize long-term capital gain or loss on the disposition of assets the Fund has owned (or is deemed to have owned) for more than one year, and short-term capital gain or loss on the disposition of investments the Fund has owned (or is deemed to have owned) for one year or less. Distributions of net-capital gain (that is, the excess of net long-term capital gain over net short-term capital loss) that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) generally will be taxable to a shareholder receiving such distributions as long-term capital gains includible in net capital gain and taxed to individuals at reduced rates relative to ordinary income. Distributions from capital gains are generally made after applying any available capital loss carryforwards. The IRS and the Department of the Treasury have issued regulations that impose special rules in respect of Capital Gain Dividends received through partnership interests constituting “applicable partnership interests” under Section 1061 of the Code. Distributions of net short-term capital gain (as reduced by any net long-term capital loss for the taxable year) will be taxable to shareholders as ordinary income. Distributions of investment income properly reported by the Fund and, in the case of the Fund investing in a Portfolio treated as a RIC, the Portfolio, as derived from “qualified dividend income” will be taxed in the hands of individuals at the rates applicable to net capital gain, provided holding period and other requirements are met at each of the shareholder, the Portfolio and, in the case of the Fund investing in a Portfolio treated as a RIC, the Fund level.

The Code generally imposes a 3.8% Medicare contribution tax on the net investment income of certain individuals, trusts and estates to the extent their income exceeds certain threshold amounts. For these purposes, “net investment income” generally includes, among other things, (i) distributions paid by the Fund of net investment income and capital gains, and (ii) any net gain from the sale, redemption, exchange or other taxable disposition of Fund shares. Shareholders are advised to consult their tax advisors regarding the possible implications of this additional tax on their investment in the Fund.

If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated earnings and profits in any taxable year, the excess distribution will be treated as a return of capital to the extent of such shareholder's tax basis in its shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces a shareholder's tax basis in its shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition by the shareholder of its shares.

Shareholders of the Fund will be subject to U.S. federal income taxes as described herein on distributions made by the Fund whether received in cash or reinvested in additional shares of the Fund.

Distributions with respect to the Fund's shares are generally subject to U.S. federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when the Fund's NAV includes either unrealized gains, or realized but undistributed income or gains

that were therefore included in the price the shareholder paid. Such distributions may reduce the fair market value of the Fund's shares below the shareholder's cost basis in those shares. As described above, the Fund is required to distribute realized income and gains regardless of whether the Fund's NAV also reflects unrealized losses.

In order for some portion of the dividends received by the Fund shareholder to be “qualified dividend income,” the Fund must meet holding period and other requirements with respect to the dividend-paying stocks held by the Fund or Portfolio, the shareholder must meet holding period and other requirements with respect to the Fund's shares, and in the case of the Fund investing in a Portfolio treated as a RIC, the Fund must meet holding period and other requirements with respect to its shares in the Portfolio. In general, a dividend will not be treated as qualified dividend income (at any of the Portfolio, Fund or shareholder level, as applicable) (a) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (b) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (c) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (d) if the dividend is received from a foreign corporation that is (i) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (ii) treated as a passive foreign investment company.

In general, distributions of investment income properly reported by the Fund as derived from qualified dividend income will be treated as qualified dividend income in the hands of a shareholder taxed as an individual, provided the shareholder meets the holding period and other requirements described above with respect to the Fund's shares. If the aggregate qualified dividends (a) received by the Fund (including from a Portfolio that is treated as a RIC) or (b) allocated to the Fund by a Portfolio that is treated as a partnership, during any taxable year are 95% or more of the Fund's gross income (excluding net long-term capital gain over net short-term capital loss), then 100% of the Fund's dividends (other than dividends properly reported as Capital Gain Dividends) will be eligible to be treated as qualified dividend income.

In general, dividends of net investment income received by corporate shareholders of a Fund will qualify for the dividends-received deduction generally available to corporations only to the extent of the amount of eligible dividends received by a Fund from domestic corporations for the taxable year. A dividend received by a Fund will not be treated as a dividend eligible for the dividends-received deduction (a) if it has been received with respect to any share of stock that the Fund has held for less than 46 days (91 days in the case of certain preferred stock) during the 91-day period beginning on the date which is 45 days before the date on which such share becomes ex-dividend with respect to such dividend (during the 181-day period beginning 90 days before such date in the case of certain preferred stock) or (b) to the extent that the Fund is under an obligation (pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property. Moreover, the dividends-received deduction may otherwise be disallowed or reduced (x) if the corporate shareholder fails to satisfy the foregoing requirements with respect to its shares of the Fund or (y) by application of various provisions of the Code (for instance, the dividends-received deduction is reduced in the case of a dividend received on debt-financed portfolio stock (generally, stock acquired with borrowed funds)).

Any distribution of income that is attributable to (a) income received by the Fund in lieu of dividends with respect to securities on loan pursuant to a securities lending transaction or (b) dividend income received by the Fund on securities it temporarily purchased from a counterparty pursuant to a repurchase agreement that is treated for U.S. federal income tax purposes as a loan by the Fund, will not constitute qualified dividend income to individual shareholders and will not be eligible for the dividends-received deduction for corporate shareholders.

Distributions by a Portfolio to its shareholders that the Portfolio properly reports as “Section 199A dividends,” as defined and subject to certain conditions described below, are treated as qualified REIT dividends in the hands of non-corporate shareholders. Non-corporate shareholders are permitted a U.S. federal income tax deduction equal to 20% of qualified REIT dividends received by them, subject to certain limitations. Very generally, a “Section 199A dividend” is any dividend or portion thereof that is attributable to certain dividends received by a RIC from REITs (as defined below), to the extent such dividends are properly reported as such by the RIC in a written notice to its shareholders. A Section 199A dividend is treated as a qualified REIT dividend only if the shareholder receiving such dividend holds the dividend-paying RIC shares for at least 46 days of the 91-day period beginning 45 days before the shares become ex-dividend, and is not under an obligation to make related payments with respect to a position in substantially similar or related property. A Portfolio is permitted to report such part of its dividends as Section 199A dividends as are eligible, but is not required to do so.

If the Fund holds, directly or indirectly, one or more “tax credit bonds” issued on or before December 31, 2017, on one or more applicable dates during a taxable year, the Fund may elect to permit its shareholders to claim a tax credit on their income tax returns equal to each shareholder's proportionate share of tax credits from the bond otherwise allowed to the Fund. In such a case, a shareholder will be deemed to receive a distribution of money with respect to its Fund shares equal to the shareholder's proportionate share of the amount of such credits and be allowed a credit against the shareholder's U.S. federal income tax liability equal to the amount of such deemed distribution. A shareholder's ability to claim a tax credit associated with one or more tax credit bonds may be subject to certain limitations imposed by the Code, and the amount of the tax credits may not exceed the amount reported by the Fund in a written notice to shareholders. Even if the Fund is eligible to pass through tax credits to shareholders, the Fund may choose not to do so.

As required by federal law, detailed federal tax information with respect to each calendar year will be furnished to each shareholder early in the succeeding year.

Tax Considerations Applicable to Portfolio Investments and Underlying Funds Treated as RICs

The Fund seeks to achieve its investment objectives by investing substantially all of its investable assets in one or more Underlying Funds and each such Underlying Fund intends to elect to be treated and to qualify and be eligible each year to be treated as a RIC. Whether a Target Retirement Fund meets the asset diversification test described above will thus depend in part on whether the Underlying Funds in which it invests meet each of the income, asset diversification, and distribution tests. If an Underlying were to fail to meet any such test and were ineligible to or otherwise were not to cure such failure, the corresponding Fund might as a result itself fail to meet the asset diversification test and might be ineligible or unable to or might otherwise not cure such failure.

The Fund's distributable income and gains will normally consist substantially of distributions from the Underlying Funds in which it invests. To the extent that a Portfolio or Underlying Fund realizes net losses on its investments for a given taxable year, the corresponding Fund will not be able to benefit from those losses until and only to the extent that (i) the Portfolio or Underlying Fund realizes gains that it can reduce by those losses, or (ii) the Fund recognizes its share of those losses when it disposes of shares of the Portfolio or Underlying Fund in a transaction qualifying for sale or exchange treatment. Moreover, even when the Fund does make such a disposition, any loss will be recognized as a capital loss, a portion of which may be a long-term capital loss. The Fund will not be able to offset any capital losses from its dispositions of shares of the Underlying Funds against its ordinary income (including distributions of any net short-term capital gains realized by a Portfolio or Underlying Fund), and the Fund's long-term capital losses first offset its long-term capital gains, increasing the likelihood that the Fund's short-term capital gains are distributed to shareholders as ordinary income.

In addition, in certain circumstances, the “wash sale” rules under Section 1091 of the Code may apply to the Fund's sales of the Underlying Fund shares that have generated losses. A wash sale occurs if shares of an issuer are sold by the Fund at a loss and the Fund acquires additional shares of that same issuer 30 days before or after the date of the sale. The wash-sale rules could defer losses in the Fund's hands on Underlying Fund shares (to the extent such sales are wash sales) for extended (and, in certain cases, potentially indefinite) periods of time.

The foregoing rules may cause the tax treatment of the Fund's gains, losses and distributions to differ at times from the tax treatment that would apply if the Fund invested directly in the types of securities held by the Underlying Funds. As a result, investors may receive taxable distributions earlier and recognize higher amounts of capital gain or ordinary income than they otherwise would.

Finally, a RIC generally must look through its 20 percent voting interest in a corporation, including a RIC, to the underlying assets thereof for purposes of the diversification test; special rules potentially provide limited relief from the application of this rule where a RIC owns such an interest in an underlying RIC (as defined below), such as a Portfolio or Underlying Fund.

Tax Implications of Certain Fund Investments

Investments in Other RICs. If the Fund receives dividends from a Portfolio treated as a RIC, or an Underlying Fund, or another underlying RIC (each, an “underlying RIC”) or a Portfolio or an Underlying Fund receives dividends from an underlying RIC, and the underlying RIC reports such dividends as qualified dividend income, then the Fund, the Portfolio or the Underlying Fund, as applicable, is permitted, in turn, to report a portion of such dividends as “qualified dividend income” when it distributes such portion to its shareholders, provided holding period and other requirements are met.

If the Fund, a Portfolio or Underlying Fund receives dividends from an underlying RIC, and the underlying RIC reports such dividends as eligible for the dividends-received deduction, then the Fund, the Portfolio or the Underlying Fund, as applicable, is permitted, in turn, to report a portion of such dividends as eligible for the dividends-received deduction as well when it distributes such portion to its shareholders, provided holding period and other requirements are met.

If an underlying RIC in which the Fund, a Portfolio or Underlying Fund invests elects to pass through tax credit bond credits to its shareholders, then the Fund, the Portfolio or Underlying Fund is permitted in turn to elect to pass through its proportionate share of those tax credits to its shareholders, provided that the Fund, the Portfolio or the Underlying Fund, as applicable, meets shareholder notice and other requirements.

The foregoing rules may cause the tax treatment of the Fund's gains, losses and distributions to differ at times from the tax treatment that would apply if the Fund invested directly in the types of securities held by the underlying RIC. As a result, investors may receive taxable distributions earlier and recognize higher amounts of capital gain or ordinary income than they otherwise would.

Special Rules for Debt Obligations. Some debt obligations with a fixed maturity date of more than one year from the date of issuance (and zero-coupon debt obligations with a fixed maturity date of more than one year from the date of issuance) will be treated as debt obligations that are issued originally at a discount. Generally, OID is treated as interest income and is included in the Fund's income and required to be distributed by the Fund over the term of the debt obligation, even though payment of that amount is not received until a later time, upon partial or full repayment or disposition of the debt obligation. In addition, payment-in-kind obligations will give rise to income which is required to be distributed and is taxable even though the Fund holding the obligation receives no interest payment in cash on the obligation during the year.

Some debt obligations with a fixed maturity date of more than one year from the date of issuance that are acquired in the secondary market by the Fund may be treated as having “market discount.” Very generally, market discount is the excess of the stated redemption price of a debt obligation (or in the case of an obligation issued with OID, its “revised issue price”) over the purchase price of such obligation. Generally, any gain recognized on the disposition of, and any partial payment of principal on, a debt obligation having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the “accrued market discount” on such debt obligation. Alternatively, the Fund may elect to accrue market discount currently, in which case the Fund will be required to include the accrued market discount in income (as ordinary income) and thus distribute it over the term of the debt obligation, even though payment of that amount is not received until a later time, upon partial or full repayment or disposition of the debt obligation. If the Fund makes the election referred to in the preceding sentence, then the rate at which the market discount accrues, and thus is included in the Fund's income, will depend upon which of the permitted accrual methods the Fund elects.

If the Fund holds the foregoing kinds of obligations, or other obligations subject to special rules under the Code, the Fund may be required to pay out as an income distribution each year an amount which is greater than the total amount of cash interest the Fund actually received. Such distributions may be made from the cash assets of the Fund or, if necessary, by disposition of portfolio securities including at a time when it may not be advantageous to do so. These dispositions may cause the Fund to realize higher amounts of short-term capital gains (generally taxed to shareholders at ordinary income tax rates) and, in the event the Fund realizes net capital gains from such transactions, its shareholders may receive a larger Capital Gain Dividend than they would have if the Fund had not held such obligations.

A portion of the OID accrued on certain high yield discount obligations may not be deductible to the issuer and will instead be treated as a dividend paid by the issuer for purposes of the dividends-received deduction. In such cases, if the issuer of the high yield discount obligations is a domestic corporation, dividend payments by the Fund may be eligible for the dividends-received deduction to the extent attributable to the deemed dividend portion of such OID.

Securities Purchased at a Premium. Very generally, where the Fund purchases a bond at a price that exceeds the redemption price at maturity – that is, at a premium — the premium is amortizable over the remaining term of the bond. In the case of a taxable bond, if the Fund makes an election applicable to all such bonds it purchases, which election is irrevocable without consent of the IRS, the Fund reduces the current taxable income from the bond by the amortized premium and reduces its tax basis in the bond by the amount of such offset; upon the disposition or maturity of such bonds acquired on or after January 4, 2013, the Fund is permitted to deduct any remaining premium allocable to a prior period.

At-risk or Defaulted Securities. Investments in debt obligations that are at risk of or in default present special tax issues for the Fund. Tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, OID or market discount; whether, when or to what extent the Fund should recognize market discount on debt obligations; when and to what extent the Fund may take deductions for bad debts or worthless securities; and how the Fund should allocate

payments received on obligations in default between principal and income. These and other related issues will be addressed by the Fund when, as and if it invests in such securities, in order to seek to ensure that it distributes sufficient income to preserve its status as a RIC and does not become subject to U.S. federal income or excise tax.

Certain Investments in REITs. Any investment by the Fund in equity securities of real estate investment trusts qualifying as such under Subchapter M of the Code (“REITs”) may result in the Fund's receipt of cash in excess of the REIT's earnings; if the Fund distributes these amounts, these distributions could constitute a return of capital to Fund shareholders for U.S. federal income tax purposes. Dividends received by the Fund from a REIT will not qualify for the corporate dividends-received deduction and generally will not constitute qualified dividend income.

Certain Investments in Mortgage Pooling Vehicles. The Fund may invest directly or indirectly in residual interests in real estate mortgage investment conduits (“REMICs”) (including by investing in residual interests in CMOs with respect to which an election to be treated as a REMIC is in effect) or equity interests in taxable mortgage pools (“TMPs”). Under a notice issued by the IRS in October 2006 and Treasury regulations that have yet to be issued but may apply retroactively, a portion of the Fund's income (including income allocated to the Fund from certain pass-through entities) that is attributable to a residual interest in a REMIC or an equity interest in a TMP (referred to in the Code as an “excess inclusion”) will be subject to U.S. federal income tax in all events. This notice also provides, and the regulations are expected to provide, that excess inclusion income of a RIC, such as the Fund, will be allocated to shareholders of the RIC in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related interest directly. As a result, a RIC investing in such securities may not be a suitable investment for charitable remainder trusts (“CRTs”), as noted below.

In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (“UBTI”) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and that otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign shareholder will not qualify for any reduction in U.S. federal withholding tax. A shareholder will be subject to U.S. federal income tax on such inclusions notwithstanding any exemption from such income tax otherwise available under the Code.

Foreign Currency Transactions. Any transaction by the Fund in foreign currencies, foreign currency-denominated debt obligations or certain foreign currency options, futures contracts or forward contracts (or similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned. Any such net gains could require a larger dividend toward the end of the calendar year. Any such net losses will generally reduce and potentially require the recharacterization of prior ordinary income distributions. Such ordinary income treatment may accelerate the Fund's distributions to shareholders and increase the distributions taxed to shareholders as ordinary income. Any net ordinary losses so created cannot be carried forward by the Fund to offset income or gains earned in subsequent taxable years.

Passive Foreign Investment Companies. Equity investments by the Fund in certain “passive foreign investment companies” (“PFICs”) could potentially subject the Fund to a U.S. federal income tax (including interest charges) on distributions received from the company or on proceeds received from the disposition of shares in the company. This tax cannot be eliminated by making distributions to Fund shareholders. However, the Fund may elect to avoid the imposition of that tax. For example, the Fund may elect to treat a PFIC as a “qualified electing fund” (i.e., make a “QEF election”), in which case the Fund will be required to include its share of the PFIC 's income and net capital gains annually, regardless of whether it receives any distribution from the PFIC. The Fund also may make an election to mark the gains (and to a limited extent losses) in such holdings “to the market” as though it had sold (and, solely for purposes of this mark-to-market election, repurchased) its holdings in those PFICs on the last day of the Fund's taxable year. Such gains and losses are treated as ordinary income and loss. The QEF and mark-to-market elections may accelerate the recognition of income (without the receipt of cash) and increase the amount required to be distributed by the Fund to avoid taxation. Either of these elections therefore may require the Fund to liquidate other investments (including when it is not advantageous to do so) to meet its distribution requirement, which also may accelerate the recognition of gain and affect the Fund's total return. Dividends paid by PFICs will not be eligible to be treated as “qualified dividend income.”

Because it is not always possible to identify a foreign corporation as a PFIC, the Fund may incur the tax and interest charges described above in some instances.

Options and Futures. In general, option premiums received by the Fund are not immediately included in the income of the Fund. Instead, the premiums are recognized when the option contract expires, the option is exercised by the holder, or the Fund transfers or otherwise terminates the option (e.g., through a closing transaction). If a call option written by the Fund is exercised and the Fund sells or delivers the underlying stock, the Fund generally will recognize capital gain or loss equal to (a) the sum of the strike price and the option premium received by the Fund minus (b) the Fund's basis in the stock. Such gain or loss generally will be short-term or long-term depending upon the holding period of the underlying stock. If securities are purchased by the Fund pursuant to the exercise of a put option written by it, the Fund generally will subtract the premium received for purposes of computing its cost basis in the securities purchased. Gain or loss arising in respect of a termination of the Fund's obligation under an option other than through the exercise of the option will be short-term gain or loss depending on whether the premium income received by the Fund is greater or less than the amount paid by the Fund (if any) in terminating the transaction. Thus, for example, if an option written by the Fund expires unexercised, the Fund generally will recognize short-term gain equal to the premium received.

The Fund's options activities may include transactions constituting straddles for U.S. federal income tax purposes, that is, that trigger the U.S. federal income tax straddle rules contained primarily in Section 1092 of the Code. Such straddles include, for example, positions in a particular security, or an index of securities, and one or more options that offset the former position, including options that are “covered” by the Fund's long position in the subject security. Very generally, where applicable, Section 1092 requires (i) that losses be deferred on positions deemed to be offsetting positions with respect to “substantially similar or related property,” to the extent of unrealized gain in the latter, and (ii) that the holding period of such a straddle position that has not already been held for the long-term holding period be terminated and begin anew once the position is no longer part of a straddle. Options on single stocks that are not “deep in the money” may constitute qualified covered calls, which generally are not subject to the straddle rules; the holding period on stock underlying qualified covered calls that are “in the money” although not “deep in the money” will be suspended during the period that such calls are outstanding. Thus, the straddle rules and the rules governing qualified covered calls could cause gains that would otherwise constitute long-term capital gains to be treated as short-term capital gains, and distributions that would otherwise constitute “qualified dividend income” or qualify for the dividends-received deduction to fail to satisfy the holding period requirements and therefore to be taxed as ordinary income or fail to qualify for the dividends-received deduction, as the case may be.

The tax treatment of certain positions entered into by the Fund, including regulated futures contracts, certain foreign currency positions and certain listed non-equity options, will be governed by Section 1256 of the Code (“Section 1256 contracts”). Gains or losses on Section 1256 contracts generally are considered 60% long-term and 40% short-term capital gains or losses (“60/40”), although certain foreign currency gains and losses from such contracts may be treated as ordinary in character. Also, Section 1256 contracts held by the Fund at the end of each taxable year (and, for purposes of the 4% excise tax, on certain other dates as prescribed under the Code) are “marked to market” with the result that unrealized gains or losses are treated as though they were realized and the resulting gain or loss is treated as ordinary or 60/40 gain or loss, as applicable.

Derivatives, Hedging, and Related Transactions. In addition to the special rules described above in respect of futures and options transactions, the Fund's transactions in other derivatives instruments (e.g., forward contracts and swap agreements), as well as any of its hedging, short sale, securities loan or similar transactions, may be subject to one or more special tax rules (e.g., notional principal contract, straddle, constructive sale, wash sale and short sale rules). These rules may affect whether gains and losses recognized by the Fund are treated as ordinary or capital, accelerate the recognition of income or gains to the Fund, defer losses to the Fund, and cause adjustments in the holding periods of the Fund's securities, thereby affecting whether capital gains and losses are treated as short-term or long-term. These rules could therefore affect the amount, timing and/or character of distributions to shareholders.

Because these and other tax rules applicable to these types of transactions are in some cases uncertain under current law, an adverse determination or future guidance by the IRS with respect to these rules (which determination or guidance could be retroactive) may affect whether the Fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a RIC and avoid the Fund-level tax.

Commodity-Linked Instruments. The Fund's direct or indirect investments in commodities and commodity-linked instruments can be limited by the Fund's intention to qualify as a RIC, and can bear on the Fund's ability to so qualify. Income and gains from commodities and certain commodity-linked instruments does not constitute qualifying income to a RIC for purposes of the 90% gross income test described above. The tax treatment of some other commodity-linked instruments in which the Fund might invest is not certain, in particular with respect to whether income or gains from such instruments constitute qualifying income to a RIC. If the Fund were to treat income or gain from a particular instrument as

qualifying income and the income or gain were later determined not to constitute qualifying income and, together with any other nonqualifying income, caused the Fund's nonqualifying income to exceed 10% of its gross income in any taxable year, the Fund would fail to qualify as a RIC unless it is eligible to and does pay a tax at the Fund level.

Book-Tax Differences. Certain of the Fund's investments in derivatives instruments and foreign currency-denominated instruments, and any of the Fund's transactions in foreign currencies and hedging activities, are likely to produce a difference between its book income and the sum of its taxable income and net tax-exempt income (if any). If such a difference arises, and the Fund's book income is less than the sum of its taxable income and net tax-exempt income, the Fund could be required to make distributions exceeding book income to qualify as a RIC that is accorded special tax treatment and to avoid an entity-level tax. In the alternative, if the Fund's book income exceeds the sum of its taxable income (including realized capital gains) and net tax-exempt income, the distribution (if any) of such excess generally will be treated as (i) a dividend to the extent of the Fund's remaining earnings and profits (including earnings and profits arising from tax-exempt income), (ii) thereafter, as a return of capital to the extent of the recipient's basis in its shares, and (iii) thereafter as gain from the sale or exchange of a capital asset.

Foreign Taxation

The Fund's income, proceeds and gains from sources within foreign countries may be subject to non-U.S. withholding or other taxes, which will reduce the yield on those investments. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If, at the close of the Fund's taxable year, more than 50% of the assets of the Fund consists of the securities of foreign corporations, the Fund may elect to permit shareholders to claim a credit or deduction (but not both) on their income tax returns for their pro rata portions of qualified taxes paid by the Fund to foreign countries in respect of foreign securities that the Fund has held for at least the minimum period specified in the Code. In such a case, shareholders will include in gross income from foreign sources their pro rata shares of such taxes paid by such Fund. A shareholder's ability to claim an offsetting foreign tax credit or deduction in respect of foreign taxes paid by the Fund is subject to certain limitations imposed by the Code, which may result in the shareholder's not receiving a full credit or deduction (if any) for the amount of such taxes. Shareholders who do not itemize on their U.S. federal income tax returns may claim a credit (but not a deduction) for such foreign taxes. Even if the Fund were eligible to make such an election for a given year, it may determine not to do so.

If the Fund does not qualify for or does not make such election, shareholders will not be entitled to claim a credit or deduction with respect to foreign taxes paid by the Fund; in that case the foreign tax will nonetheless reduce the Fund's taxable income. Shareholders that are not subject to U.S. federal income tax, and those who invest in the Fund through tax-advantaged accounts (including those who invest through individual retirement accounts or other tax-advantaged retirement plans), generally will receive no benefit from any tax credit or deduction passed through by the Fund, if any. Under certain circumstances, if the Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Fund Shares could be affected or any foreign tax credits or deductions passed through to shareholders in respect of the Fund's foreign taxes for the current year could be reduced.

If at the close of each quarter of its taxable year, at least 50% of the total assets of the Fund consists of interests in other RICs (such as a Portfolio or Underlying Fund treated as a RIC), such Fund will be a “qualified fund of funds.” In that case, the Fund is permitted to elect to pass through to its shareholders foreign income and other similar taxes paid by the Fund in respect of foreign securities held directly by the Fund or by the underlying RIC in which it invests that itself elected to pass such taxes through to shareholders. However, even if the Fund qualifies to make such election for any year, it may determine not to do so. Shareholders that are not subject to U.S. federal income tax, and those who invest in the Fund through tax-advantaged accounts (including those who invest through individual retirement accounts or other tax-advantaged retirement plans), generally will receive no benefit from any tax credit or deduction passed through by the Fund.

Backup Withholding

The Fund generally is required to withhold and remit to the U.S. Treasury a percentage of the taxable distributions and redemption proceeds paid to any individual shareholder who fails to properly furnish the Fund with a correct taxpayer identification number (“TIN”), who has under-reported dividend or interest income, or who fails to certify to the Fund that he or she is not subject to such withholding.

Backup withholding is not an additional tax. Any amounts withheld may be credited against the shareholder's U.S. federal income tax liability, provided the appropriate information is furnished to the IRS.

Tax-Exempt Shareholders

Income of a RIC that would be UBTI if earned directly by a tax-exempt entity will not generally constitute UBTI when distributed to a tax-exempt shareholder of the RIC. Notwithstanding this “blocking” effect, a tax-exempt shareholder could realize UBTI by virtue of its investment in the Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Code Section 514(b).

A tax-exempt shareholder may also recognize UBTI if the Fund recognizes “excess inclusion income” derived from direct or indirect investments in residual interests in REMICs or equity interests in TMPs if the amount of such income recognized by the Fund exceeds the Fund's investment company taxable income (after taking into account deductions for dividends paid by the Fund).

In addition, special tax consequences apply to charitable remainder trusts (“CRTs”) that invest in RICs that invest directly or indirectly in residual interests in REMICs or equity interests in TMPs. Under legislation enacted in December 2006, a CRT (as defined in Section 664 of the Code) that realizes any UBTI for a taxable year must pay an excise tax annually of an amount equal to such UBTI.

Under IRS guidance issued in October 2006, a CRT will not recognize UBTI as a result of investing in a RIC that recognizes “excess inclusion income.” Rather, if at any time during any taxable year a CRT (or one of certain other tax-exempt shareholders, such as the United States, a state or political subdivision, or an agency or instrumentality thereof, and certain energy cooperatives) is a record holder of a share in a RIC that recognizes “excess inclusion income,” then the RIC will be subject to a tax on that portion of its “excess inclusion income” for the taxable year that is allocable to such shareholders at the highest U.S. federal corporate income tax rate. The extent to which this IRS guidance remains applicable in light of the December 2006 legislation is unclear. To the extent permitted under the 1940 Act, the Fund may elect to specially allocate any such tax to the applicable CRT, or other shareholder, and thus reduce such shareholder's distributions for the year by the amount of the tax that relates to such shareholder's interest in the Fund. CRTs are urged to consult their tax advisors concerning the consequences of investing in the Fund.

Redemptions and Exchanges

Redemptions and exchanges of the Fund's shares are taxable events and, accordingly, shareholders may realize gain or loss on these transactions. In general, any gain or loss realized upon a taxable disposition of shares will be treated as long-term capital gain or loss if the shares have been held for more than 12 months. Otherwise, the gain or loss on the taxable disposition of Fund shares will be treated as short-term capital gain or loss. However, any loss realized upon a taxable disposition of Fund shares held by a shareholder for six months or less will be treated as long-term, rather than short-term, to the extent of any Capital Gain Dividends received (or deemed received) by the shareholder with respect to the shares. Further, all or a portion of any loss realized upon a taxable disposition of Fund shares generally will be disallowed under the Code's “wash sale” rule if other substantially identical shares are purchased, including by means of dividend reinvestment, within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

Upon the redemption or exchange of shares of the Fund, the Fund or, in the case of shares purchased through a financial intermediary, the financial intermediary may be required to provide you and the IRS with cost basis and certain other related tax information about the Fund shares you redeemed or exchanged. See the Fund's prospectuses for more information.

Tax Shelter Reporting

Under U.S. Treasury regulations, if a shareholder recognizes a loss of at least $2 million in any single taxable year or $4 million in any combination of taxable years for an individual shareholder or at least $10 million in any taxable year or $20 million in any combination of taxable years for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a RIC are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all RICs. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Shareholders should consult their tax advisers to determine the applicability of these regulations in light of their individual circumstances.

Non-U.S. Shareholders

Non-U.S. shareholders in the Fund should consult their tax advisors concerning the tax consequences of ownership of shares in the Fund. Distributions by the Fund to shareholders that are not “U.S. persons” within the meaning of the Code ( “foreign shareholders”) properly reported by the Fund as (1) Capital Gain Dividends, (2) short-term capital gain dividends, and (3) interest-related dividends, each as defined and subject to certain conditions described below, generally are not subject to withholding of U.S. federal income tax.

In general, the Code defines (1) “short-term capital gain dividends” as distributions of net short-term capital gains in excess of net long-term capital losses and (2) “interest-related dividends” as distributions from U.S.-source interest income of types similar to those not subject to U.S. federal income tax if earned directly by an individual foreign shareholder, in each case to the extent such distributions are properly reported as such by the Fund in a written notice to shareholders.

The exceptions to withholding for Capital Gain Dividends and short-term capital gain dividends do not apply to (A) distributions to an individual foreign shareholder who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution and (B) distributions attributable to gain that is treated as effectively connected with the conduct by the foreign shareholder of a trade or business within the United States under special rules regarding the disposition of “U.S. real property interests” (“USRPIs”) as described below. The exception to withholding for interest-related dividends does not apply to distributions to a foreign shareholder (i) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (ii) to the extent that the dividend is attributable to certain interest on an obligation if the foreign shareholder is the issuer or is a 10% shareholder of the issuer, (iii) that is within certain foreign countries that have inadequate information exchange with the United States, or (iv) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign shareholder and the foreign shareholder is a controlled foreign corporation). If the Fund invests in a RIC that pays such distributions to the Fund, such distributions retain their character as not subject to withholding if properly reported when paid by the Fund to foreign shareholders. A RIC is permitted to report such parts of its dividends as are eligible to be treated as interest-related or short-term capital gain dividends, but it is not required to do so. In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports all or a portion of a payment as an interest-related or short-term capital gain dividend to shareholders.

Foreign shareholders should contact their intermediaries regarding the application of withholding rules to their accounts.

Distributions by the Fund to foreign shareholders other than Capital Gain Dividends, short-term capital gain dividends and interest-related dividends (e.g., dividends attributable to dividend and foreign-source interest income or to short-term capital gains or U.S. source interest income to which the exception from withholding described above does not apply) are generally subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate).

A foreign shareholder is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund unless (a) such gain is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (b) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale and certain other conditions are met, or (c) the special rules relating to gain attributable to the sale or exchange of USRPIs apply to the foreign shareholder's sale of shares of the Fund (as described below).

Foreign shareholders with respect to whom income from the Fund is effectively connected with a trade or business conducted by the foreign person within the United States will in general be subject to U.S. federal income tax on the income derived from the Fund at the graduated rates applicable to U.S. citizens, residents or domestic corporations, whether such income is received in cash or reinvested in shares of the Fund and, in the case of a foreign corporation, may also be subject to a branch profits tax. If a foreign shareholder is eligible for the benefits of a tax treaty, any effectively connected income or gain will generally be subject to U.S. federal income tax on a net basis only if it is also attributable to a permanent establishment maintained by the shareholder in the United States. More generally, foreign shareholders who are residents in a country with an income tax treaty with the United States may obtain different tax results than those described herein, and are urged to consult their tax advisors.

Special rules would apply if the Fund were a qualified investment entity (“QIE”) because it is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition thereof. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation's USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs are generally defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the

last five years. The Fund that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and RICs that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in RICs generally are not USRPIs, but these exceptions do not apply for purposes of determining whether the Fund is a QIE. If an interest in the Fund were a USRPI, the Fund would be required to withhold U.S. tax on the proceeds of a share redemption by a greater-than-5% foreign shareholder, in which case such foreign shareholder generally would also be required to file U.S. tax returns and pay any additional taxes due in connection with the redemption.

If the Fund were a QIE under a special “look-through” rule, any distributions by the Fund to a foreign shareholder attributable directly or indirectly to (i) distributions received by the Fund from a lower-tier RIC or REIT that the Fund is required to treat as USRPI gain in its hands and (ii) gains realized on the disposition of USRPIs by the Fund, would retain their character as gains realized from USRPIs in the hands of the Fund's foreign shareholders and would be subject to U.S. tax withholding. In addition, such distributions could result in the foreign shareholder being required to file a U.S. tax return and pay tax on the distributions at regular U.S. federal income tax rates. The consequences to a foreign shareholder, including the rate of such withholding and character of such distributions (e.g., as ordinary income or USRPI gain), would vary depending upon the extent of the foreign shareholder's current and past ownership of the Fund. The Fund generally does not expect that it will be a QIE.

Foreign shareholders of the Fund also may be subject to “wash sale” rules to prevent the avoidance of the tax-filing and –payment obligations discussed above through the sale and repurchase of Fund shares.

Foreign shareholders should consult their tax advisers and, if holding shares through intermediaries, their intermediaries, concerning the application of these rules to their investment in the Fund.

In order for a foreign shareholder to qualify for any exemptions from withholding described above or for lower withholding tax rates under income tax treaties, or to establish an exemption from back-up withholding, the foreign shareholder must comply with special certification and filing requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, IRS Form W-8BEN-E or substitute form). Foreign shareholders in the Fund should consult their tax advisers in this regard. Special rules (including withholding and reporting requirements) apply to foreign partnerships and those holding Fund shares through foreign partnerships. Additional considerations may apply to foreign trusts and estates. Investors holding Fund shares through foreign entities should consult their tax advisers about their particular situation.

A foreign shareholder may be subject to state and local tax and to the U.S. federal estate tax in addition to the U.S. federal income tax on income referred to above.

Shareholder Reporting Obligations with Respect to Foreign Bank and Financial Accounts

Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of the Fund by vote or value could be required to report annually their “financial interest” in the Fund's “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in the Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.

Other Reporting and Withholding Requirements

Sections 1471-1474 of the Code and the U.S. Treasury and IRS guidance issued thereunder (collectively, “FATCA”) generally require the Fund to obtain information sufficient to identify the status of each of its shareholders under FATCA or under an applicable intergovernmental agreement (an “IGA”) between the United States and a foreign government. If a shareholder fails to provide the requested information or otherwise fails to comply with FATCA or an IGA, the Fund may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on ordinary dividends it pays. The IRS and the Department of Treasury have issued proposed regulations providing that these withholding rules will not apply to the gross proceeds of share redemptions or Capital Gain Dividends the Fund pays. If a payment by the Fund is subject to FATCA withholding, the Fund is required to withhold even if such payment would otherwise be exempt from withholding under the rules applicable to foreign shareholders described above (e.g., short-term capital gain dividends and interest-related dividends).

Each prospective investor is urged to consult its tax adviser regarding the applicability of FATCA and any other reporting requirements with respect to the prospective investor's own situation, including investments through an intermediary.

APPENDIX A

RATINGS OF DEBT INSTRUMENTS

MOODY'S INVESTORS SERVICE, INC. (“MOODY'S”)

GLOBAL LONG-TERM RATING SCALE

Ratings assigned on Moody's global long-term rating scale are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default.

Aaa: Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.

Aa: Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A: Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.

Baa: Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.

Ba: Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high credit risk.

Caa: Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.

Ca: Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody's appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category. Additionally, a “(hyb)” indicator is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms.*

By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

GLOBAL SHORT-TERM RATING SCALE

Ratings assigned on Moody's global short-term rating scale are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default.

P-1: Ratings of Prime-1 reflect a superior ability to repay short-term obligations.

P-2: Ratings of Prime-2 reflect a strong ability to repay short-term obligations.

P-3: Ratings of Prime-3 reflect an acceptable ability to repay short-term obligations.

NP: Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

A-1

S&P GLOBAL RATINGS (“S&P”)

ISSUE CREDIT RATING DEFINITIONS

An S&P Global Ratings issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P Global Ratings' view of the obligor's capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS*

AAA: An obligation rated ‘AAA' has the highest rating assigned by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is extremely strong.

AA: An obligation rated ‘AA' differs from the highest-rated obligations only to a small degree. The obligor's capacity to meet its financial commitments on the obligation is very strong.

A: An obligation rated ‘A' is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor's capacity to meet its financial commitments on the obligation is still strong.

BBB: An obligation rated ‘BBB' exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken the obligor's capacity to meet its financial commitments on the obligation.

BB; B; CCC; CC; and C: Obligations rated ‘BB', ‘B', ‘CCC', ‘CC', and ‘C' are regarded as having significant speculative characteristics. ‘BB' indicates the least degree of speculation and ‘C' the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposure to adverse conditions.

BB: An obligation rated ‘BB' is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to the obligor's inadequate capacity to meet its financial commitments on the obligation.

B: An obligation rated ‘B' is more vulnerable to nonpayment than obligations rated ‘BB', but the obligor currently has the capacity to meet its financial commitments on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitments on the obligation.

CCC: An obligation rated ‘CCC' is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitments on the obligation.

CC: An obligation rated ‘CC' is currently highly vulnerable to nonpayment. The ‘CC' rating is used when a default has not yet occurred, but S&P Global Ratings expects default to be a virtual certainty, regardless of the anticipated time to default.

C: An obligation rated ‘C' is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared with obligations that are rated higher.

D: An obligation rated ‘D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D' rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D' rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. A rating on an obligation is lowered to 'D' if it is subject to a distressed debt restructuring.

NR: This indicates that a rating has not been assigned or is no longer assigned.

A-2

Ratings from 'AA' to 'CCC' may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the rating categories.

SHORT-TERM ISSUE CREDIT RATINGS

A-1: A short-term obligation rated ‘A-1' is rated in the highest category by S&P Global Ratings. The obligor's capacity to meet its financial commitments on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor's capacity to meet its financial commitments on these obligations is extremely strong.

A-2: A short-term obligation rated ‘A-2' is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor's capacity to meet its financial commitments on the obligation is satisfactory.

A-3: A short-term obligation rated ‘A-3' exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to weaken an obligor's capacity to meet its financial commitments on the obligation.

B: A short-term obligation rated ‘B' is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties that could lead to the obligor's inadequate capacity to meet its financial commitments.

C: A short-term obligation rated ‘C' is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitments on the obligation.

D: A short-term obligation rated ‘D' is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D' rating category is used when payments on an obligation are not made on the date due, unless S&P Global Ratings believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D' rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation's rating is lowered to ‘D' if it is subject to a distressed exchange offer.

FITCH RATINGS. (“FITCH”)

ISSUER DEFAULT RATINGS

Rated entities in a number of sectors, including financial and non-financial corporations, sovereigns, insurance companies and certain sectors within public finance, are generally assigned Issuer Default Ratings (IDRs). IDRs are also assigned to certain entities in global infrastructure and project finance. IDRs opine on an entity's relative vulnerability to default on financial obligations. The threshold default risk addressed by the IDR is generally that of the financial obligations whose non-payment would best reflect the uncured failure of that entity. As such, IDRs also address relative vulnerability to bankruptcy, administrative receivership or similar concepts.

In aggregate, IDRs provide an ordinal ranking of issuers based on the agency's view of their relative vulnerability to default, rather than a prediction of a specific percentage likelihood of default.

AAA: Highest credit quality.

‘AAA' ratings denote the lowest expectation of default risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA: Very high credit quality.

‘AA' ratings denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality.

‘A' ratings denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

A-3

BBB: Good credit quality.

‘BBB' ratings indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.

BB: Speculative.

‘BB' ratings indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists that supports the servicing of financial commitments.

B: Highly speculative.

‘B' ratings indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.

CCC: Substantial credit risk.

Very low margin for safety. Default is a real possibility.

CC: Very high levels of credit risk.

Default of some kind appears probable.

C: Near default

A default or default-like process has begun, or the issuer is in standstill, or for a closed funding vehicle, payment capacity is irrevocably impaired. Conditions that are indicative of a ‘C' category rating for an issuer include:

the issuer has entered into a grace or cure period following non-payment of a material financial obligation;

the issuer has entered into a temporary negotiated waiver or standstill agreement following a payment default on a material financial obligation;

the formal announcement by the issuer or their agent of a distressed debt exchange;

a closed financing vehicle where payment capacity is irrevocably impaired such that it is not expected to pay interest and/or principal in full during the life of the transaction, but where no payment default is imminent.

RD: Restricted default.

‘RD' ratings indicate an issuer that in Fitch's opinion has experienced:

an uncured payment default or distressed debt exchange on a bond, loan or other material financial obligation, but

has not entered into bankruptcy filings, administration, receivership, liquidation, or other formal winding-up procedure, and

has not otherwise ceased operating.

This would include:

the selective payment default on a specific class or currency of debt;

ii.

the uncured expiry of any applicable grace period, cure period or default forbearance period following a payment default on a bank loan, capital markets security or other material financial obligation;

iii.

the extension of multiple waivers or forbearance periods upon a payment default on one or more material financial obligations, either in series or in parallel; ordinary execution of a distressed debt exchange on one or more material financial obligations.

D: Default.

‘D' ratings indicate an issuer that in Fitch's opinion has entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure or that has otherwise ceased business.

A-4

Default ratings are not assigned prospectively to entities or their obligations; within this context, non-payment on an instrument that contains a deferral feature or grace period will generally not be considered a default until after the expiration of the deferral or grace period, unless a default is otherwise driven by bankruptcy or other similar circumstance, or by a distressed debt exchange.

In all cases, the assignment of a default rating reflects the agency's opinion as to the most appropriate rating category consistent with the rest of its universe of ratings and may differ from the definition of default under the terms of an issuer's financial obligations or local commercial practice.

SHORT-TERM RATINGS ASSIGNED TO ISSUERS AND OBLIGATIONS

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.

F1: Highest Short-Term Credit Quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2: Good Short-Term Credit Quality. Good intrinsic capacity for timely payment of financial commitments.

F3: Fair Short-Term Credit Quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B: Speculative Short-Term Credit Quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

C: High Short-Term Default risk. Default is a real possibility.

RD: Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.

D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Note: The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories. For example, the rating category ‘AA' has three notch-specific rating levels (‘AA+'; ‘AA'; ‘AA-'; each a rating level). Such suffixes are not added to ‘AAA' ratings and ratings below the 'CCC' category. For the short-term rating category of ‘F1', a ‘+' may be appended. For Viability Ratings, the modifiers “+” or “–” may be appended to a rating to denote relative status within categories from ‘AA' to ‘CCC'. For derivative counterparty ratings the modifiers “+” or “–” may be appended to the ratings within ‘AA(dcr)' to ‘CCC(dcr)' categories.
