Affiliated ETP Risk . The Adviser may receive management or other fees from Affiliated ETPs, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Portfolio and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Portfolio and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Portfolio invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the Portfolio may invest in determining whether, and under what circumstances, to purchase or sell shares in that Affiliated ETP. Although the Adviser takes steps to address the conflicts of interest, it is possible that the conflicts could impact the Portfolio and, therefore, the Fund.

Agriculture Companies Risk . Economic forces, including forces affecting agricultural markets, as well as government policies and regulations affecting agriculture companies, could adversely impact a Portfolio's investments. Agricultural and livestock production and trade flows are significantly affected by government policies and regulations. Governmental policies affecting agriculture companies, such as taxes, tariffs, duties, subsidies and import and export restrictions on agricultural commodities, commodity products and livestock, can influence agriculture company profitability, the planting/raising of certain crops/livestock versus other uses of resources, the location and size of crop and livestock production, whether unprocessed or processed commodity products are traded and the volume and types of imports and exports. In addition, agriculture companies must comply with a broad range of environmental laws and regulations. Additional or more stringent environmental laws and regulations may be enacted in the future and such changes could have a material adverse effect on the business of such companies. In addition, agricultural and livestock businesses may be significantly affected by adverse weather, pollution and/or disease which could limit or halt production.

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

Asset-Backed and Mortgage-Backed Securities Risk . Asset-backed and mortgage-backed securities (residential and commercial) represent interests in “pools” of mortgages or other assets, including consumer loans or receivables held in trust. These securities, in most cases, are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. These securities are subject to the risk of default on the underlying asset or mortgage, particularly during periods of economic downturn. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed and mortgage-backed securities. In particular, during periods of falling interest rates, mortgage-backed securities will be called or prepaid, which may result in a Portfolio having to reinvest proceeds in other investments at a lower interest rate. During periods of rising interest rates, the average life of a mortgage-backed security may extend, which may lock in a below-market interest rate, increase the security's duration, and reduce the value of the security. Enforcing rights against the underlying assets or collateral may be difficult, or the underlying assets or collateral may be insufficient if the issuer defaults. The values of certain types of mortgage-backed securities, such as inverse floaters and interest-only and principal-only securities, may be extremely sensitive to changes in interest rates and prepayment rates.

Bank Loan Risk . A Portfolio may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, a Portfolio will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Portfolio to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and a Portfolio may have difficulty selling them. A Portfolio may also experience settlement delays with respect to bank loan trades. Participations by the Portfolio in a lender's portion of a bank loan typically will result in the Portfolio having a contractual relationship only with such lender, not with the borrower. A Portfolio may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower. In connection with purchasing participations, a Portfolio generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and a Portfolio may not directly benefit from any collateral supporting the loan in

60

which it has purchased the participation. As a result, the Portfolio may assume the credit risk of both the borrower and the lender selling the participation. Further, loans held by a Portfolio may not be considered securities and, therefore, purchasers, such as a Portfolio, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws.

Below Investment-Grade Securities Risk . Securities rated below investment-grade and unrated securities of comparable credit quality (commonly known as “high-yield bonds” 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 a Portfolio defaults on its payments or becomes insolvent or bankrupt, the Portfolio 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 a Portfolio may fall substantially and the Portfolio 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 a Portfolio to sell certain securities at prices used in calculating the Portfolio's net asset value. 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 a Portfolio 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 a Portfolio are prepaid. In any such case, a Portfolio may be forced to invest the prepaid amounts in lower-yielding investments, resulting in a decline in the Portfolio's income.

Cash Position Risk . A Portfolio may hold a significant portion of its assets in cash or cash equivalents in the Adviser's discretion. If a Portfolio holds a significant cash position, its investment returns may be adversely affected, and the Portfolio may not achieve its investment objective.

Collateralized Loan Obligation Risk . The risks of an investment in a collateralized loan obligation depend largely on the type of the collateral securities and the class of the debt obligation in which the Portfolio invests. Collateralized loan obligations are generally subject to credit, interest rate, valuation, liquidity, prepayment and extension risks. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn. Collateralized loan obligations carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest of other payments, (ii) the collateral may decline in value or default, (iii) the Portfolio may invest in obligations that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results.

Commodities Risk . Commodity prices can have significant volatility, and exposure to commodities can cause the net asset value 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 Portfolio 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.

61

Company Risk . Changes in the financial condition of a company or other issuer, changes in specific market, economic, political, regulatory, geopolitical, and other conditions that affect a particular type of investment or issuer, and changes in general market, economic, political, regulatory, geopolitical and other conditions can adversely affect the price of an investment. The price of securities of smaller, less well-known issuers can be more volatile than the price of securities of larger issuers or the market in general.

Convertible Securities Risk . Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer, depending on the terms of the securities) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. Convertible securities may be subordinate to other debt securities issued by the same issuer. Issuers of convertible securities are often not as strong financially as issuers with higher credit ratings. Convertible securities typically provide yields lower than comparable non-convertible securities. Their values may be more volatile than those of non-convertible securities, reflecting changes in the values of the securities into which they are convertible.

Counterparty Risk . A Portfolio will be subject to credit risk with respect to the counterparties with which the Portfolio enters into derivatives contracts and other transactions such as repurchase agreements or reverse repurchase agreements. A Portfolio'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, a Portfolio may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Portfolio. A Portfolio 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 a Portfolio 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. Contractual provisions and applicable law may prevent or delay a Portfolio from exercising its rights to terminate an investment or transaction with a financial institution experiencing financial difficulties, or to realize on collateral, and another institution may be substituted for that financial institution without the consent of the Portfolio. If the credit rating of a derivatives counterparty declines, a Portfolio may nonetheless choose or be required to keep existing transactions in place with the counterparty, in which event the Fund would be subject to any increased credit risk associated with those transactions.

Credit Risk (except for SPDR Blackstone / GSO Senior Loan ETF) . Credit risk is the risk that an issuer, guarantor or liquidity provider of a fixed-income security held by a Portfolio 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 a Portfolio 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 a Portfolio 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 a Portfolio loses its rating or its rating is downgraded, the Portfolio 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.

Credit Risk (SPDR Blackstone / GSO Senior Loan ETF only) . Issuers may not be able to repay the principal or interest on securities (including loans), which may result in the Portfolio losing money. There may be economic or political changes that impact the ability of issuers to repay principal and to make interest payments on securities. Changes to the financial condition or credit rating of issuers may also adversely affect the value of the assets of the Portfolio.

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 a Portfolio'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

62

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 a Portfolio's portfolio investments.

Debt Securities Risk . The values of debt securities may increase or decrease as a result of the following: market fluctuations, increases 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; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. 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. The U.S. is experiencing historically low interest rate levels. However, economic recovery and the tapering of the Federal Reserve Board's quantitative easing program increase the likelihood that interest rates will rise in the future. A rising interest rate environment may cause the value of a Portfolio's fixed income securities to decrease, a decline in a Portfolio's income and yield, an adverse impact on the liquidity of a Portfolio's fixed income securities, and increased volatility of the fixed income markets. 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 a Portfolio 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.

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, a Portfolio and, therefore, the corresponding 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.

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, and a Portfolio 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 or Sub-Adviser anticipated or a different or less favorable effect than the Adviser or Sub-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 a Portfolio 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 a Portfolio will experience losses on its derivatives

63

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 a Portfolio 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 shut down, and more significant governmental limitations on investment policy as compared to those typically found in a developed market. 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. A Portfolio may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Portfolio'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.

Energy Sector Risk . Issuers in energy-related industries can be significantly affected by fluctuations in energy prices and supply and demand of energy fuels caused by geopolitical events, energy conservation or use of alternative fuel sources, the success of exploration projects, weather or meteorological events, taxes, increased governmental or environmental regulation, resource depletion, rising interest rates, declines in domestic or foreign production, accidents or catastrophic events, or terrorist threats or attacks, among others. Markets for various energy-related commodities can have significant volatility, and are subject to control or manipulation by large producers or purchasers. Companies in the energy sector may need to make substantial expenditures, and to incur significant amounts of debt, in order to maintain or expand their reserves through exploration of new sources of supply, through the development of existing sources, through acquisitions, or through long-term contracts to acquire reserves. Factors adversely affecting producers, refiners, distributors, or others in the energy sector may affect adversely companies that service or supply those entities, either because demand for those services or products is curtailed, or those services or products come under price pressure.

Equity Investing Risk . The market prices of equity securities owned by a 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.

Exchange Traded Products Risk . A Fund is subject to substantially the same risks as those associated with the direct ownership of the securities or other assets represented by the ETPs in which a Fund invests. The shares of certain ETPs may trade at a premium or discount to their net asset values. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of

64

the underlying ETF's investments, which may be exacerbated in less liquid markets. By investing in ETPs, a Fund bears the proportionate share of any fees and expenses (e.g. management, custody, accounting, and administration) of the ETP, if applicable, in addition to the fees and expenses that a Fund and its shareholders directly bear in connection with the Fund's operations.

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. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Growth Stock Risk. The prices of growth stocks may be based largely on expectations of future earnings, and their prices can decline rapidly and significantly in reaction to negative news about such factors as earnings, revenues, the economy, political developments, or other news. Growth stocks may underperform value stocks and stocks in other broad style categories (and the stock market as a whole) over any period of time and may shift in and out of favor with investors generally, sometimes rapidly, depending on changes in market, economic, and other factors. As a result, at times when it holds substantial investments in growth stocks, a Portfolio may underperform other investment funds that invest more broadly or that favor different investment styles. Because growth companies typically reinvest their earnings, growth stocks typically do not pay dividends at levels associated with other types of stocks, if at all.

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

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, a Portfolio 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 a Portfolio 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 Portfolio may receive at maturity less than it invested. Depending on the changes in inflation rates during the period a Portfolio holds an inflation-indexed security, the Portfolio 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.

65

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.

Interest Rate Risk . Interest rate risk is the risk that the securities held by a Portfolio will decline in value because of increases in market 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 a Portfolio'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. The U.S. is experiencing historically low interest rate levels. However, economic recovery and the tapering of the Federal Reserve Board's quantitative easing program increase the likelihood that interest rates will rise in the future. 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 a Portfolio's investments.

Investments in Exchange Traded Commodity Trusts. An exchange traded commodity trust is a pooled trust that invests in physical commodities or commodity futures, and issues shares that are traded on a securities exchange. Shares may trade at a discount or premium to the value of the holdings of the trusts. Investments in exchange traded commodity trusts are subject to brokerage and other trading costs. Exchange traded commodity trusts are not investment companies registered under the 1940 Act and are not subject to regulation under the Commodity Exchange Act of 1936 (the “CEA”). As a result, in connection with any such investments, a Portfolio will not have the protections associated with ownership of shares in an investment company registered under the 1940 Act or the protections afforded by the CEA. As with other investments in commodities, investments in exchange traded commodity trusts may increase the risk that investors in a Portfolio may not qualify as “regulated investment companies” under the Internal Revenue Code. If an investment company investing in a Portfolio fails to qualify as a regulated investment company, that investment company may be subject to tax, potentially reducing returns to shareholders. Such a failure will also alter the treatment of distributions to its shareholders. These risks are described more thoroughly under “Tax Risk-Qualifying Income.” These risks are described more thoroughly under “Tax Risk-Qualifying Income.”

Investments in ETFs. As a shareholder of another investment company, each Portfolio relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of a Portfolio's investment could decline, which could adversely affect the Portfolio's performance. By investing in another investment company, a Fund indirectly bears the corresponding Portfolio's proportionate share of any fees and expenses of the other investment company, if applicable, in addition to the fees and expenses that the Fund and its

66

shareholders directly bear in connection with the Portfolio's and Fund's operations. A Portfolio may invest in ETFs that are not registered or regulated under the 1940 Act. These instruments typically hold commodities, such as gold or oil, currency or other property that is itself not a security (see also “Investments in Exchange Traded Commodity Trusts” below). Federal securities laws impose limitations on a Portfolio's ability to invest in other investment companies.

Because ETFs are listed on national stock exchanges and are traded like stocks listed on an exchange, their shares potentially may trade at a discount or premium. Investments in ETFs are also subject to brokerage and other trading costs, which could result in greater expenses to a Portfolio. In addition, because the value of ETF shares depends on the demand in the market and such value may deviate from the net asset value of the ETF, the Adviser may not be able to liquidate a Portfolio's holdings at the most optimal time, especially times of extreme market stress, which could adversely affect the Portfolio's and, therefore, the Fund‘s performance.

Investments in ETNs . Exchange traded notes (“ETNs”) generally are senior, unsecured, unsubordinated debt securities issued by a sponsor, such as an investment bank. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying market, changes in the applicable interest rates, and economic, legal, political or geographic events that affect the referenced market. Because ETNs are debt securities, they are subject to credit risk. If the issuer has financial difficulties or becomes insolvent or bankrupt, a Portfolio may not receive the return it was promised and could lose its entire investment. If a rating agency lowers the credit rating of the issuer of an ETN, the value of the ETN may decline; a lower credit rating reflects a greater risk that the issuer will default on its obligation. There are typically no periodic interest payments for ETNs, and the amount of principal payable at maturity may decline, depending in part on the performance of an underlying index or asset. As is the case with ETFs, an investor could lose some of or the entire amount invested in ETNs. A Portfolio's decision to sell its ETN holdings may be limited by the availability of a secondary market.

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.

Lender Liability Risk . A number of U.S. judicial decisions have upheld judgments of borrowers against lending institutions on the basis of various evolving legal theories, collectively termed “lender liability.” Generally, lender liability is founded on the premise that a lender has violated a duty (whether implied or contractual) of good faith, commercial reasonableness and fair dealing, or a similar duty owed to the borrower or has assumed an excessive degree of control over the borrower resulting in the creation of a fiduciary duty owed to the borrower or its other creditors or shareholders. Because of the nature of its investments, the Fund and/or the Portfolio may be subject to allegations of lender liability.

In addition, under common law principles that in some cases form the basis for lender liability claims, if a lender or bondholder (a) intentionally takes an action that results in the undercapitalization of a borrower to the detriment of other creditors of such borrower; (b) engages in other inequitable conduct to the detriment of such other creditors; (c) engages in fraud with respect to, or makes misrepresentations to, such other creditors or (d) uses its influence as a stockholder to dominate or control a borrower to the detriment of other creditors of such borrower, a court may elect to subordinate the claim of the offending lender or bondholder to the claims of the disadvantaged creditor or creditors, a remedy called “equitable subordination.”

Because affiliates of, or persons related to, the Adviser or Sub-Adviser may hold equity or other interests in obligors of a Portfolio, the Portfolio could be exposed to claims for equitable subordination or lender liability or both based on such equity or other holdings.

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 a Portfolio engages in transactions that have a leveraging effect on the Portfolio's investment portfolio, the value of the Portfolio 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 a Portfolio would otherwise have and so magnifies the effect of any increase or decrease in the

67

value of the Portfolio's underlying assets. The use of leverage is considered to be a speculative investment practice and may result in losses to a Portfolio and, therefore, its corresponding Fund. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The use of leverage may cause a Portfolio to liquidate positions when it may not be advantageous to do so to satisfy repayment, interest payment, or margin obligations or to meet asset segregation or coverage requirements.

Liquidity Risk. Liquidity risk is the risk that a Portfolio may not be able to dispose of securities or close out derivatives transactions readily at a favorable time or prices (or at all) or at prices approximating those at which a Portfolio 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 securities 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 a Portfolio to value illiquid securities 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 securities may entail registration expenses and other transaction costs that are higher than those for liquid securities. A Portfolio 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 Portfolio.

Furthermore, with respect to the SPDR DoubleLine Total Return Tactical ETF, if the Fund's principal investment strategies involve investing in municipal securities or high yield securities, the Fund's portfolio may have greater exposure to liquidity risk since the markets for such securities may be less liquid than the traditional bond markets. There may also be less information available on the financial condition of issuers of these types of securities than for public corporations. This means that it may be harder to buy and sell such securities, especially on short notice, and these securities may be more difficult for the Fund to value accurately than securities of public corporations.

Management Risk . Each Portfolio 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 a Portfolio and, therefore, its corresponding Fund to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

Market Risk . Market prices of investments held by a Portfolio will go up or down, sometimes rapidly or unpredictably. Each Portfolio'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, 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 a Portfolio could decline if the particular industries, sectors or companies in which the Portfolio 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.

Master Limited Partnership Risk. Investments in securities of MLPs involve certain risks different from or in addition to the risks of investing in common stocks, including for example risks related to the limited ability of investors to control an MLP and to vote on matters affecting the MLP, risks related to potential conflicts of interest between an MLP and the MLP's general partner, the risk that an MLP will generate insufficient cash flow to meet its current operating requirements, the risk that an MLP will issue additional securities or engage in other transactions that will have the effect of diluting the interests of existing investors, and risks related to the general partner's right to require unit-holders to sell their common units at an undesirable time or price. MLP common units can be affected by macro-economic and other factors affecting the stock market in general, changes or anticipated changes in interest rates, investor sentiment towards MLPs or the energy sector generally, changes in a particular issuer's financial condition, or unfavorable or unanticipated poor performance of a particular issuer (in the case of MLPs, generally measured in terms of distributable cash flow). Prices of common units of individual MLPs also can be affected by other factors unique to the partnership or company, including earnings power and coverage ratios. Certain MLP securities may trade in relatively low volumes due to their smaller capitalizations or other factors, which may cause them to have a high degree of price volatility and lack sufficient market liquidity to enable a Portfolio to effect a sale at an advantageous time or price.

68

MLP Tax Risk. MLPs do not pay U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership's income, gains, losses, deductions, and expenses. A change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being required to pay U.S. federal income tax on its taxable income. The classification of an MLP as a corporation for U.S. federal income tax purposes would likely have a significant adverse impact on the value of an investment in the MLP.

Metals and Mining Companies Risk. Metals and mining companies can be significantly affected by events relating to international political and economic developments, energy conservation, the success of exploration projects, commodity prices, and tax and other government regulations. Investments in metals and mining companies may be speculative and may be subject to greater price volatility than investments in other types of companies. Risks of metals and mining investments include: changes in international monetary policies or economic and political conditions that can affect the supply of precious metals and consequently the value of metals and mining company investments; the United States or foreign governments may pass laws or regulations limiting metals investments for strategic or other policy reasons; and increased environmental or labor costs may depress the value of metals and mining investments.

Money Market 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 increase 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. None of State Street Corporation, State Street Bank and Trust Company, State Street Global Advisors (“SSGA”), SSGA FM 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 or to impose limitations on redemptions during periods of high illiquidity in the markets for the investments held by it.

Mortgage Pass-Through Securities Risk. Most transactions in mortgage pass-through securities occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement, referred to as a “to-be-announced transaction” or “TBA Transaction”. In a TBA Transaction, the buyer and seller agree upon general trade parameters such as agency, settlement date, par amount and price. Default by, or bankruptcy of, a counterparty to a TBA Transaction would expose a Portfolio to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA Transaction. To minimize this risk, a Portfolio will enter into TBA Transactions only with established counterparties (such as major broker-dealers) and the Sub-Adviser will monitor the creditworthiness of such counterparties. Each Portfolio expects to enter into such contracts on a regular basis. A Portfolio, pending settlement of such contracts, will invest its assets in high-quality, liquid short term instruments, including shares of affiliated money market funds.

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. 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 a Portfolio having to reinvest the proceeds in other investments at lower interest rates.

69

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. 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 a Portfolio 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, a Portfolio 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 a Portfolio.

Municipal Obligations Risk. The U.S. municipal securities market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Municipal obligations include revenue obligations, which are generally backed by the revenues generated from a specific project or facility and include private activity bonds and industrial development bonds. Private activity and industrial development bonds are dependent on the ability of the facility's user to meet its financial obligations and on the value of any real or personal property pledged as security for such payment. Private activity and industrial development bonds, although issued by industrial development authorities, may be backed only by the assets of the non-governmental user. Because many municipal securities are issued to finance projects relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market. In addition, municipal securities backed by current or anticipated revenues from a specific project or specific asset can be negatively affected by the discontinuance or reduction in the rate of the taxation supporting the project or asset or the inability to collect revenues for the project or from the assets. If the U.S. Internal Revenue Service determines the issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable, and the security could decline in value. Municipal obligations may also be subject to prepayment risk and extension risk. Certain states and other governmental entities have experienced, and may continue to experience, extreme financial pressures in response to financial and economic and other factors, and may be, or be perceived to be, unable to meet all of their obligations under municipal bonds issued or guaranteed by them; such factors may result in substantial volatility in municipal securities markets and losses to a Portfolio, and, therefore, the corresponding Fund. Additionally, a Portfolio's holdings may have greater exposure to liquidity risk since the markets for such securities may be less liquid than the traditional bond markets. There may also be less information available on the financial condition of issuers of these types of securities than for public corporations. This means that it may be harder to buy and sell such securities, especially on short notice, and these securities may be more difficult for a Portfolio to value accurately than securities of public corporations.

Natural Resources Risk . Investments in companies in natural resources industries can be significantly affected by (often rapid) changes in supply of, or demand for, various natural resources. They may also be affected by changes in energy prices, international political and economic developments, environmental incidents, energy conservation, the success of exploration projects, changes in commodity prices, and tax and other government regulations.

70

Non-Diversification Risk . As a “non-diversified” fund, each Portfolio may hold a smaller number of portfolio securities than many other funds. To the extent the Portfolio invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Portfolio may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds.

Non-Senior Loans and Other Debt Securities Risk . Secured loans that are not first lien, loans that are unsecured and debt securities are subject to many of the same risks that affect Senior Loans; however they are often unsecured and/or lower in the issuer's capital structure than Senior Loans, and thus may be exposed to greater risk of default and lower recoveries in the event of a default. This risk can be further heightened in the case of below investment-grade instruments. Additionally, most fixed-income securities are fixed-rate and thus are generally more susceptible than floating rate loans to price volatility related to changes in prevailing interest rates.

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 a Portfolio'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 a Portfolio's investments 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 a Portfolio invests could cause the Portfolio's investments in that country to experience gains or losses. Certain countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions.  Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

Perpetual Bond Risk . Perpetual bonds offer a fixed return with no maturity date. Because they never mature, perpetual bonds can be more volatile than other types of bonds that have a maturity date and may have heightened sensitivity to changes in interest rates. If market interest rates rise significantly, the interest rate paid by a perpetual bond may be much lower than the prevailing interest rate.  Perpetual bonds are also subject to credit risk with respect to the issuer.  In addition, because perpetual bonds may be callable after a set period of time, there is the risk that the issuer may recall the bond.

Preferred Securities Risk . Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. Unlike debt securities, dividend payments on a preferred security typically must be declared by the issuer's board of directors. An issuer's board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on preferred securities at any time. Therefore, in the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare a dividend and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds - that is, as interest rates rise, the value of the preferred securities held by a Portfolio are likely to

71

decline. Therefore, to the extent that a Portfolio invests a substantial portion of its assets in fixed rate preferred securities, rising interest rates may cause the value of the Portfolio's investments to decline significantly. In addition, because many preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of a Portfolio's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in a Portfolio's yield.

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.

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, or to maintain its exemptions from registration under the 1940 Act, which could have adverse consequences for the Portfolio. Investments in REITs are also subject to the risks affecting equity markets generally.

Reinvestment Risk. Income from the Portfolio may decline when the Portfolio 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 Portfolio to reinvest the proceeds in lower-yielding securities. A decline in income received by the Portfolio from its investments is likely to have a negative effect on the yield and total return of the Fund Shares.

Repurchase Agreement Risk . A repurchase agreement is an agreement to buy a security from a seller at one price and a simultaneous agreement to sell it back to the original seller at an agreed-upon price, typically representing the purchase price plus interest. Repurchase agreements may be viewed as loans made by a Portfolio which are collateralized by the securities subject to repurchase. A Portfolio's investment return on such transactions will depend on the counterparty's willingness and ability to perform its obligations under a repurchase agreement. If a Portfolio's counterparty should default on its obligations and the Portfolio is delayed or prevented from recovering the collateral, or if the value of the collateral is insufficient, the Portfolio may realize a loss.

Restricted Securities Risk . A Portfolio 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

72

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.

Reverse Repurchase Agreement Risk . A reverse repurchase agreement involves the sale of a portfolio security by a Portfolio, coupled with its agreement to repurchase the instrument at a specified time and price. Reverse repurchase agreements involve the risk that the value of securities that a Portfolio is obligated to repurchase under the agreement may decline below the repurchase price. When a Portfolio enters into a reverse repurchase agreement, it is subject to the risk that the buyer (counterparty) may default on its obligations to the Portfolio, potentially resulting in delays, costs, and losses to the Portfolio. Reverse repurchase agreements involve leverage risk; a Portfolio may lose money as a result of declines in the values both of the security subject to the reverse repurchase agreement and the instruments in which the Portfolio invested the proceeds of the reverse repurchase agreement. Use of reverse repurchase agreements by a Portfolio will increase the volatility and potential losses of the Portfolio and, therefore, the Fund.

Senior Loan Risk. Investments in Senior Loans are subject to credit risk and general investment risk. Credit risk refers to the possibility that the borrower of a Senior Loan will be unable and/or unwilling to make timely interest payments and/or repay the principal on its obligation. Default in the payment of interest or principal on a Senior Loan will result in a reduction in the value of the Senior Loan and consequently a reduction in the value of a Portfolio's investments and a potential decrease in the NAV of the Portfolio. Senior Loans are also subject to the risk that the value of the collateral securing a Senior Loan may decline, be insufficient to meet the obligations of the borrower or be difficult to liquidate. In addition, a Portfolio's access to the collateral may be limited by bankruptcy or other insolvency laws. Further, loans held by the Portfolio may not be considered securities and, therefore, purchasers, such as the Portfolio, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws. Some Senior Loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the Senior Loans to presently existing or future indebtedness of the borrower or take other action detrimental to lenders, including a Portfolio, such as invalidation of Senior Loans or causing interest previously paid to be refunded to the borrower. Senior Loans are also subject to high yield securities risks and liquidity risks described below.

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 a Portfolio, limit the ability of a Portfolio to reinvest the proceeds of a sale of securities, hinder the ability of a Portfolio to lend its portfolio securities, and potentially subject a Portfolio to penalties for its failure to deliver to on-purchasers of securities whose delivery to a Portfolio was delayed. Delays in the settlement of securities purchased by a Portfolio may limit the ability of the Portfolio to sell those securities at times and prices it considers desirable, and may subject the Portfolio to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. A Portfolio 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.

Sovereign Debt Obligations Risk . Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. A governmental entity's willingness or ability to pay interest and repay principal in a timely manner may be affected by a variety of factors, including its cash flow, the size of its reserves, its access to foreign exchange, the relative size of its debt service burden to its economy as a whole, and political constraints. A governmental entity may default on its obligations or may require renegotiation or reschedule of debt payments. Any restructuring of a sovereign debt obligation held by a Portfolio will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Portfolio may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt. The sovereign debt of many non-U.S. governments, including their sub-divisions and instrumentalities, is rated below investment-grade. Sovereign debt risk may be greater for debt securities issued or guaranteed by emerging and/or frontier countries.

Tax Risk-Qualifying Income . Regulated investment companies are subject to favorable tax treatment under the Internal Revenue Code. To qualify as a regulated investment company, a Fund must derive at least 90% of its gross income for each taxable year from sources generating “qualifying income.” Income derived from direct and certain indirect

73

investments in commodities is not qualifying income. Thus, income from a Portfolio's investments in certain commodities-related investments may cause  the corresponding Fund not to qualify as a regulated investment company. To the extent a Portfolio invests in exchange traded commodity trusts, or makes other commodities-related investments that may generate income that is not qualifying income,  the corresponding Fund will seek to restrict the resulting income from such investments so that the Fund's non-qualifying income does not exceed 10% of its gross income. However, a Portfolio might generate more non-qualifying income than anticipated, might not be able to generate qualifying income in a particular taxable year at levels sufficient to meet the qualifying income test, or might not be able to determine the percentage of qualifying income it derives for a taxable year until after year-end. A Portfolio may also invest up to 25% of its total assets in one or more QPTPs, including ETPs that are QPTPs and whose principal activities are the buying and selling of commodities or options, futures, or forwards with respect to commodities. Although income from QPTPs is generally qualifying income, if an ETP intending to qualify as a QPTP fails to qualify as a QPTP, the income generated from a Portfolio's investment in the ETP may not be qualifying income. There can be no guarantee that any ETP will be successful in qualifying as a QPTP. In addition, there is little regulatory guidance concerning the application of the rules governing qualification as a QPTP, and it is possible that future guidance may adversely affect the qualification of ETPs as QPTPs.

Under certain circumstances, the Fund may be able to cure a failure to meet the qualifying income test, but in order to do so the Fund may incur significant Fund-level taxes, which would effectively reduce (and could eliminate) the Fund's returns. If the Fund fails to qualify as a regulated investment company, the Fund will be subject to tax, which will reduce returns to shareholders. Such a failure will also alter the treatment of distributions to shareholders.

Unconstrained Sector Risk . A Portfolio 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 Portfolio 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 Portfolio than if it had not focused its assets in that industry, market, or economic sector, which may increase the volatility of the Portfolio.

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 one major rating agency has introduced greater uncertainty about the ability of the U.S. to repay its obligations. A further credit rating downgrade or a U.S. credit default could decrease the value and increase the volatility of a Portfolio's investments.

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 a Portfolio‘s U.S. Treasury obligations to decline. The total public debt of the United States as a percentage of gross domestic product has grown rapidly since the beginning of the recent financial downturn. 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

74

lead to inflation), and can prevent the U.S. government from implementing effective counter-cyclical fiscal policy in economic downturns. U.S. Treasury securities are currently given the top rating by all major ratings agencies except Standard & Poor's Ratings Services, which rates them AA+, one grade below their top rating. Since downgrading U.S. Treasury securities from AAA to AA+ in 2011, Standard & Poor's Ratings Services has affirmed its rating. A downgrade of the ratings of U.S. government debt obligations, such as U.S. Treasury 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. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade below AA+ rating by Standard & Poor's Ratings Services may cause the value of a Portfolio's U.S. Treasury obligations to decline.

Valuation Risk . Some portfolio holdings, potentially a large portion of a Portfolio'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 a Portfolio could sell or close out a portfolio position for the value established for it at any time, and it is possible that a Portfolio would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Portfolio at that time. Investors who purchase or redeem Fund Shares on days when a Portfolio is holding fair-valued investments may receive fewer or more shares or lower or higher redemption proceeds than they would have received if a Portfolio had not fair-valued the holding(s) or had used a different valuation methodology.

Value Stock Risk. Value stocks present the risk that they may decline in price or never reach their expected full market value, either because the market fails to recognize the stock's intrinsic worth or the Adviser or Sub-Adviser overestimates the stock's expected value. Value stocks may underperform growth stocks and stocks in other broad style categories (and the stock market as a whole) over any period of time and may shift in and out of favor with investors generally, sometimes rapidly, depending on changes in market, economic, and other factors. As a result, at times when it holds substantial investments in value stocks a Portfolio may underperform other investment portfolios that invest more broadly or that favor different investment styles.

Variable and Floating Rate Securities Risk . Variable or floating rate securities are debt securities with variable or floating interest rates payments. Variable or floating rate securities bear rates of interest that are adjusted periodically according to formulae intended generally to reflect market rates of interest and allow a Portfolio to participate (determined in accordance with the terms of the securities) in increases in interest rates through upward adjustments of the coupon rates on the securities. However, during periods of increasing interest rates, changes in the coupon rates may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. A Portfolio may also invest in variable or floating rate equity securities, whose dividend payments vary based on changes in market rates of interest or other factors.

In addition, investment in derivative variable rate securities, such as inverse floaters, whose rates vary inversely with market rates of interest, or range floaters or capped floaters, whose rates are subject to periodic or lifetime caps, or in securities that pay a rate of interest determined by applying a multiple to the variable rate involves special risks as compared to investment in a fixed-rate security and may involve leverage. The extent of increases and decreases in the values of derivative variable rate securities and the corresponding change to the net asset value of a Fund in response to changes in market rates of interest generally may be larger than comparable changes in the value of an equal principal amount of a fixed-rate security having similar credit quality, redemption provisions, and maturity. The markets for such securities may be less developed and may have less liquidity than the markets for conventional securities.

When-Issued, TBA and Delayed Delivery Securities Risk. A Portfolio may purchase securities on a when-issued, 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

75

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 a Fund's net asset value. Default by, or bankruptcy of, a counterparty to a when-issued, TBA or delayed delivery transaction would expose a Portfolio 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. Recently finalized rules of the Financial Industry Regulatory Authority, Inc. impose mandatory margin requirements for certain types of when-issued, TBA delayed delivery or forward commitment transactions, with limited exceptions. Such transactions historically have not been required to be collateralized, and mandatory collateralization could increase the cost of such transactions and impose added operational complexity.

Non-Principal Risks

Each risk discussed below is a non-principal risk of a Fund to the extent it is not identified as a principal risk for such Fund in the preceding “ADDITIONAL RISK INFORMATION - PRINCIPAL RISKS” section.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. A Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”), which are responsible for the creation and redemption activity for a Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Conflicts of Interest Risk. An investment in a Fund may be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to a 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 Portfolio may invest in other pooled investment vehicles sponsored, managed, or otherwise affiliated with the Adviser. There is no assurance that the rates at which a 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 makes available to other clients. Because of its financial interest, the Adviser may have an incentive to enter into transactions or arrangements on behalf of a Fund with itself or its affiliates in circumstances where it might not have done so in the absence of that interest.

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 Funds. 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 a Portfolio 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 a Portfolio. 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 Funds and Portfolios) 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 a Fund or Portfolio. A Fund or Portfolio may encounter circumstances, or enter into transactions, in which conflicts of interest that are not listed or discussed above may arise.

Costs of Buying and Selling Shares . Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for Fund Shares (the “bid” price) and the price at which an investor is willing to sell Fund Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for Fund Shares based on trading volume and market liquidity, and is

76

generally lower if Fund Shares have more trading volume and market liquidity and higher if Fund Shares have little trading volume and market liquidity. Further, increased market volatility may cause increased bid/ask spreads. Due to the costs of buying or selling Fund Shares, including bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

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 Funds and the Portfolio) 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 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, a Fund, a Portfolio, the Adviser, a sub-adviser, or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect a Fund or its shareholders. For instance, cyber-attacks or technical malfunctions may interfere with the processing of shareholder or other transactions, affect a Fund's ability to calculate its NAV, cause the release of private shareholder information or confidential Fund information, impede trading, cause reputational damage, and subject a 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 a Fund inaccessible or inaccurate or incomplete. A Fund may also incur substantial costs for cybersecurity risk management in order to prevent cyber incidents in the future. A Fund and its shareholders could be negatively impacted as a result. While the Adviser and/or the Sub-Adviser have 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. Each 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. Similar types of cybersecurity risks or technical malfunctions also are present for issuers of securities in which each Portfolio invests, which could result in material adverse consequences for such issuers, and may cause a Portfolio's investment in such securities to lose value.

Fluctuation of Net Asset Value, Share Premiums and Discounts . The net asset value of Fund Shares will generally fluctuate with changes in the market value of a Fund's securities holdings. The market prices of Fund Shares will generally fluctuate in accordance with changes in a Fund's net asset value and supply and demand of Fund Shares on the Exchange. It cannot be predicted whether Fund Shares will trade below, at or above their net asset value. Each Portfolio and its holdings in ETFs are subject to the same market forces. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Fund Shares will be closely related to, but not identical to, the same forces influencing the prices of the securities trading individually or in the aggregate at any point in time. The market prices of Fund Shares may deviate significantly from the net asset value of Fund Shares during periods of market volatility. However, given that Fund Shares can be created and redeemed in Creation Units (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Adviser (and Sub-Adviser, as applicable) believes that large discounts or premiums to the net asset value of Fund Shares should not be sustained over long periods. While the creation/redemption feature is designed to make it likely that Fund Shares normally will trade close to a Fund's net asset value, disruptions to creations and redemptions or market volatility may result in trading prices that differ significantly from such Fund's net asset value. If an investor purchases Fund Shares at a time when the market price is at a premium to the net asset value of Fund Shares or sells at a time when the market price is at a discount to the net asset value of Fund Shares, then the investor may sustain losses.

Master/Feeder Structure Risk. Each Fund pursues its objective by investing substantially all of its assets in another pooled investment vehicle (a “master fund”). The ability of the Fund to meet its investment objective is directly related to the ability of the master fund to meet its investment objective. The ability of the Fund to meet its objective may be adversely affected by the purchase and redemption activities of other investors in the master fund. The ability of the Fund to meet redemption requests will depend on its ability to redeem its interest in the master fund. The Adviser or an affiliate serves as investment adviser to the master fund, leading to potential conflicts of interest. For example, the

77

Adviser or its affiliates will receive fees based on the amount of assets invested in the master fund. Investment by the Fund in the master fund may be beneficial in the management of the master fund, 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 master fund 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 such master fund over a master fund 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 master fund 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 master fund sponsored or managed by the Adviser or its affiliates at prices and at times more favorable than those at which the Fund does so. A Fund will bear its pro rata portion of the expenses incurred by the master fund.

Money Market 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 increase 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. None of State Street Corporation, State Street Bank and Trust Company, State Street Global Advisors (“SSGA”), SSGA FM 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 or to impose limitations on redemptions during periods of high illiquidity in the markets for the investments held by it.

Portfolio Turnover Risk . A Portfolio may engage in frequent trading of its portfolio securities. Portfolio turnover generally involves a number of direct and indirect costs and expenses to a Portfolio, 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 a Portfolio's investment return, and the sale of securities by a Portfolio may result in the realization of taxable capital gains, including short-term capital gains.

Securities Lending Risk . Each Portfolio may lend portfolio securities with a value of up to 40% 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, and a Portfolio will receive cash or other obligations as collateral. Any such loans must be continuously secured by collateral in cash or cash equivalents maintained on a current basis in an amount at least equal to the market value of the securities loaned by a Portfolio. In a loan transaction, as compensation for lending its securities, a Portfolio will receive a portion of the dividends or interest accrued on the securities held as collateral or, in the case of cash collateral, a portion of the income from the investment of such cash. In addition, a Portfolio 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. A Portfolio will call loans to vote proxies if a material issue affecting the investment is to be voted upon. Should the borrower of the securities fail financially, a Portfolio 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, a Portfolio will also bear the risk of any decline in value of securities acquired with cash collateral. A Portfolio will attempt to minimize this risk by limiting the investment of cash collateral to high quality instruments of short maturity.

Trading Issues . Although Fund Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for such Fund Shares will develop or be maintained. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to

78

Exchange “circuit breaker” rules. Similar to the shares of operating companies listed on a stock exchange, shares of a Fund may be sold short and are therefore subject to the risk of increased volatility in the trading price of the Fund's shares. While each Fund expects that the ability of Authorized Participants to create and redeem Fund shares at net asset value should be effective in reducing any such volatility, there is no guarantee that it will eliminate the volatility associated with such short sales. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of a Fund will continue to be met or will remain unchanged or that Fund Shares will trade with any volume, or at all, on any stock exchange.

In addition to the preceding information, the following provides information regarding non-principal risks specific to the SPDR Blackstone / GSO Senior Loan ETF only:

Limitations on Transactions with Affiliates Risk . The 1940 Act limits the Portfolio's ability to enter into certain transactions with certain of its affiliates, including affiliates of the Sub-Adviser. As a result of these restrictions, the Portfolio may be prohibited from buying or selling any security directly from or to any portfolio company of a registered investment company or private equity fund managed by any affiliate of the Sub-Adviser, including The Blackstone Group L.P. The 1940 Act also prohibits certain “joint” transactions with certain of the Sub-Adviser's affiliates. These limitations may limit the scope of investment opportunities that would otherwise be available to the Portfolio.

Potential Conflicts of Interest Risk . The Sub-Adviser will be subject to certain conflicts of interest in its management of the Portfolio. In the ordinary course of their business activities, the Sub-Adviser and its affiliates may engage in activities where the interests of certain divisions of the Sub-Adviser and its affiliates or the interests of their clients may conflict with the interests of the Portfolio or the interestholders of the Portfolio. As part of its regular business, the Sub-Adviser or its affiliates provide a broad range of investment management, advisory, and other services. Because of such relationships, there may be certain investments that the Sub-Adviser will decline or be unable to make. In addition, employees of such affiliates may possess information relating to such issuers that is not known to the individuals at the Sub-Adviser. Those employees of the Sub-Adviser's affiliates will not be obligated to share any such information with the Sub-Adviser and may be prohibited by law or contract from doing so. The Sub-Adviser or certain of its affiliates may come into possession of material non-public information with respect to an issuer. Should this occur, the Sub-Adviser would be restricted from buying or selling securities or loans of the issuer on behalf of the Portfolio until such time as the information became public or was no longer deemed material, so as to preclude the Portfolio from participating in an investment.

(1)

The Adviser has contractually agreed to waive its management fee and/or reimburse certain expenses, until October 31, 2018, so that the net annual Fund operating expenses, before application of any fees and expenses not paid by the Adviser pursuant to the Investment Advisory Agreement, if any, are limited to 0.55% of the Fund's average daily net assets. The contractual fee waiver and/or reimbursement does not provide for the recoupment by the Adviser of any fees the Adviser previously waived. The Adviser may continue the waiver and/or reimbursement from year to year, but there is no guarantee that the Adviser will do so and after October 31, 2018, the waiver and/or reimbursement may be cancelled or modified at any time. This waiver and/or reimbursement may not be terminated prior to October 31, 2018 except with the approval of the Fund's Board of Trustees.

From time to time, the Adviser may waive all or a portion of its management fee. The Adviser has contractually agreed to waive its management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for each Fund until October 31, 2018. This waiver and/or reimbursement does not provide for the recoupment by the Adviser of any amounts waived or reimbursed. This waiver and/or reimbursement may not be terminated prior to October 31, 2018 except with the approval of the Funds' Board of Trustees. The Adviser pays all expenses of each Fund other than the management fee, brokerage expenses, taxes, interest, fees and expenses of the Independent Trustees (including any Trustee's counsel fees), litigation expenses, acquired fund fees and expenses and other extraordinary expenses.

Investment Sub-Advisers. The Adviser may hire one or more sub-advisers to oversee the day-to-day investment activities of the Portfolios and the Funds. The sub-advisers are subject to oversight by the Adviser. The Adviser, the Trust and SSGA Master Trust have received an exemptive order from the SEC that permits the Adviser, with the approval of the Independent Trustees of the respective Trust, to retain and amend existing sub-advisory agreements with unaffiliated investment sub-advisers for the Portfolios and the Funds without submitting the sub-advisory agreement to a vote of the Portfolio's and Fund's shareholders. The respective Trust will notify shareholders in the event of any change in the identity of such sub-adviser or sub-advisers. The Adviser has ultimate responsibility for the investment performance of the Portfolios and the Funds due to its responsibility to oversee each sub-adviser and recommend their hiring, termination and replacement. The Adviser is not required to disclose fees paid to any sub-adviser retained pursuant to the order.

PORTFOLIO MANAGERS

SPDR SSGA Multi-Asset Real Return ETF, SPDR SSGA Income Allocation ETF and SPDR SSGA Global Allocation ETF (the “Asset Allocation ETFs”)

The Adviser manages each Fund and each Portfolio using a team of investment professionals. The team approach is used to create an environment that encourages the flow of investment ideas. The portfolio managers within each 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. Each portfolio management team is overseen by the SSGA Investment Committee.

The professionals primarily responsible for the day-to-day management of each Fund and each Portfolio are:

Timothy Furbush, CFA, CMT, is a Vice President of SSGA and the Adviser and a Senior Portfolio Manager in the Investment Solutions Group (ISG). He is responsible for developing and implementing customized investment approaches for clients, including strategic and tactical global balanced funds as well as equitization and overlay strategies. Prior to his current role, Mr. Furbush worked for SSGA's Intermediary Business Group as a research analyst providing value added research, educational tools and practice management services to financial advisors. Before rejoining SSGA in 2007, Mr. Furbush spent a year at Fidelity Investments as a research analyst on their Consultant Relations Team. A graduate of Stonehill College, Mr. Furbush has a Master of Science in Finance from the Sawyer School of Management at Suffolk University. He has earned both the Chartered Financial Analyst (CFA) and Chartered Market Technician (CMT) designations. He is a member of the CFA Institute, CFA Society Boston, Inc. and the Market Technicians Association.

Robert Guiliano is a Vice President of SSGA and the Adviser and a Senior Portfolio Manager in the Investment Solutions Group (ISG).

Additional Purchase and Sale Information

Fund Shares are listed for secondary trading on the Exchange and individual Fund Shares may only be purchased and sold in the secondary market through a broker-dealer. The secondary markets are closed on weekends and also are generally closed on the following holidays: New Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day (observed), Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Exchange

84

may close early on the business day before certain holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If you buy or sell Fund Shares in the secondary market, you will pay the secondary market price for Fund Shares. In addition, you may incur customary brokerage commissions and charges and may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

The trading prices of Fund Shares will fluctuate continuously throughout trading hours based on market supply and demand rather than the relevant Fund's net asset value, which is calculated at the end of each business day. Fund Shares will trade on the Exchange at prices that may be above ( i.e ., at a premium) or below ( i.e ., at a discount), to varying degrees, the daily net asset value of Fund Shares. The trading prices of Fund Shares may deviate significantly from the relevant Fund's net asset value during periods of market volatility. Given, however, that Fund Shares can be issued and redeemed daily in Creation Units, the Adviser believes that large discounts and premiums to net asset value should not be sustained over long periods. Information showing the number of days the market price of Fund Shares was greater than the relevant Fund's net asset value and the number of days it was less than the relevant Fund's net asset value ( i.e ., premium or discount) for various time periods is available by visiting the Funds' website at https://www.spdrs.com .

The Exchange will disseminate, every fifteen seconds during the regular trading day, an indicative optimized portfolio value (“IOPV”) relating to the Funds. The IOPV calculations are estimates of the value of the Funds' net asset value per Fund Share using market data converted into U.S. dollars at the current currency rates. The IOPV price is based on quotes and closing prices from the securities' local market and may not reflect events that occur subsequent to the local market's close. Premiums and discounts between the IOPV and the market price may occur. This should not be viewed as a “real-time” update of the net asset value per Fund Share, which is calculated only once a day. Neither the Funds nor the Adviser or any of their affiliates are involved in, or responsible for, the calculation or dissemination of such IOPVs and make no warranty as to their accuracy.

The Funds do not impose any restrictions on the frequency of purchases and redemptions; however, the Funds reserve the right to reject or limit purchases at any time as described in the SAI. When considering that no restriction or policy was necessary, the Board evaluated the risks posed by market timing activities, such as whether frequent purchases and redemptions would interfere with the efficient implementation of a Fund's investment strategy, or whether they would cause a Fund to experience increased transaction costs. The Board considered that, unlike traditional mutual funds, Fund Shares are issued and redeemed only in large quantities of shares known as Creation Units, available only from a Fund directly, and that most trading in a Fund occurs on the Exchange at prevailing market prices and does not involve the Fund directly. Given this structure, the Board determined that it is unlikely that (a) market timing would be attempted by a Fund's shareholders or (b) any attempts to market time a Fund by shareholders would result in negative impact to the Fund or its shareholders.

Investments by Registered Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including the Fund Shares. These restrictions are discussed in the Funds' SAI.

Distributions

Dividends and Capital Gains. As a Fund shareholder, you are entitled to your share of the applicable Fund's income and net realized gains on its investments. Each Fund pays out substantially all of its net earnings to its shareholders as “distributions.”

Through its investment in a Portfolio, each Fund may earn dividends from stocks, interest from debt securities and, if participating, securities lending income. These amounts, net of expenses and taxes (if applicable), are passed along to Fund shareholders as “income dividend distributions.” Each Fund will generally be treated as realizing short-term capital gains or losses whenever its corresponding Portfolio sells or exchanges assets held for one year or less. Net short-term capital gains will generally be treated as ordinary income when distributed to shareholders. Each Fund will generally be treated as realizing long-term capital gains or losses whenever its corresponding Portfolio sells or exchanges assets held for more than one year. Net capital gains (the excess of a Fund's net long-term capital gains over its net short-term capital losses) are distributed to shareholders as “capital gain distributions.”

85

Income dividend distributions, if any, for the following Funds are generally distributed to shareholders quarterly, but may vary significantly from period to period: Asset Allocation ETFs and MFS Systematic Equity ETFs. Income dividend distributions, if any, for the following Funds are generally distributed to shareholders monthly, but may vary significantly from period to period: SPDR Blackstone / GSO Senior Loan ETF, SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF.

Net capital gains for each Fund are distributed at least annually. Dividends may be declared and paid more frequently or at any other times to comply with the distribution requirements of the Internal Revenue Code.

Distributions in cash may be reinvested automatically in additional whole Fund Shares only if the broker through whom you purchased Fund Shares makes such option available. Distributions which are reinvested will nevertheless be taxable to the same extent as if such distributions had not been reinvested.

Portfolio Holdings Disclosure

The Funds' portfolio holdings disclosure policy is described in the SAI. In addition, the identities and quantities of the securities held by each Portfolio are disclosed on the Funds' website.

Additional Tax Information

The following discussion is a summary of some important U.S. federal tax considerations generally applicable to an investment in a Fund. Your investment in a 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.

Each Fund has elected or will elect to be a regulated investment company and intends to qualify each year to be treated as such. A regulated investment company is generally not subject to tax at the corporate level on income and gains that are distributed to shareholders. However, a Fund's failure to qualify for treatment as a regulated investment company may result in corporate level taxation, and consequently, a reduction in income available for distribution to shareholders.

Each Portfolio expects to be treated as a partnership for federal income tax purposes. Thus, the Portfolios generally will not themselves be subject to federal income tax. Instead, each Portfolio will allocate to the corresponding Fund the Fund's share of the Portfolio's net investment income, net realized capital gains, and any other items of income, gain, loss, deduction, or credit.

In general, a Fund will not recognize gain or loss for federal income tax purposes when it invests in a Portfolio or when it receives distributions or makes withdrawals from a Portfolio unless cash distributions or withdrawals exceed the Fund's adjusted tax basis in its interest in the Portfolio.

Taxes on Distributions. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in a Fund. The income dividends and short-term capital gains distributions you receive from a Fund will be taxed as either ordinary income or qualified dividend income. Subject to certain limitations, dividends that are reported by a Fund as qualified dividend income are taxable to noncorporate shareholders at rates of up to 20%. Any distributions of a Fund's net capital gains are taxable as long-term capital gain regardless of how long you have owned Fund Shares. Long-term capital gains are generally taxed to noncorporate shareholders at rates of up to 20%. Distributions in excess of a Fund's current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the applicable Fund's shares, and, in general, as capital gain thereafter.

In general, dividends may be reported by a Fund as qualified dividend income if they are attributable to qualified dividend income received by its corresponding Portfolio, which, in general, includes dividend income received by the Portfolio from taxable U.S. corporations and certain foreign corporations ( i.e ., certain foreign corporations incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, and certain other foreign corporations if the stock with respect to which the dividend is paid is readily tradable on an established securities market in the United States), provided that the Portfolio and Fund satisfy certain holding period requirements in respect of the stock of such corporations and have not hedged their position in the stock in certain ways. A dividend generally will not be treated as qualified dividend income if the dividend is received with respect to any share of stock held by a Portfolio for fewer than 61 days during the 121-day period beginning at the date which is

86

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, for fewer than 91 days during the 181-day period beginning 90 days before such date. These holding period requirements will also apply to your ownership of Fund Shares. Holding periods may be suspended for these purposes for stock that is hedged. Additionally, income derived in connection with a Fund's securities lending activities will not be treated as qualified dividend income.

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% Medicare contribution tax on all or a portion of their “net investment income,” which includes taxable interest, dividends and certain capital gains (generally including capital gain distributions and capital gains realized upon the sale of Fund Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

If a Fund redeems Creation Units in cash, it may bear additional costs and recognize more capital gains than it would if it redeems Creation Units in-kind.

If you lend your Fund Shares pursuant to securities lending arrangements you may lose the ability to treat Fund dividends (paid while the Fund Shares are held by the borrower) as qualified dividend income. You should consult your financial intermediary or tax advisor to discuss your particular circumstances.

Distributions paid in January, but declared by a Fund in October, November or December of the previous year, payable to shareholders of record in such a month, may be taxable to you in the calendar year in which they were declared. The Funds will inform you of the amount of your ordinary income dividends, qualified dividend income and capital gain distributions shortly after the close of each calendar year.

A distribution will reduce a Fund's net asset value per Fund Share and may be taxable to you as ordinary income or capital gain even though, from an investment standpoint, the distribution may constitute a return of capital.

Original Issue Discount . Investments by a Portfolio in zero coupon or other discount securities will result in income to the Portfolio equal to a portion of the excess face value of the securities over their issue price (the “original issue discount” or “OID”) each year that the securities are held, even though the Portfolio may receive no cash interest payments or may receive cash interest payments that are less than the income recognized for tax purposes. In other circumstances, whether pursuant to the terms of a security or as a result of other factors outside the control of a Portfolio, a Portfolio may recognize income without receiving a commensurate amount of cash. A Fund‘s share of such income is included in determining the amount that the Fund must distribute to maintain its eligibility for treatment as a regulated investment company and to avoid the payment of federal tax, including the nondeductible 4% excise tax. Where such income is not matched by a corresponding cash receipt by a Portfolio, the Portfolio or the Fund may be required to borrow money or dispose of securities to enable the Fund to make distributions to its shareholders in order to qualify for treatment as a regulated investment company and eliminate taxes at the Fund level, potentially resulting in additional taxable gain or loss to the Fund.

Inflation-Indexed Bonds. Special rules apply if a Portfolio holds inflation-indexed bonds. Generally, all stated interest on inflation-indexed bonds is taken into income by a Portfolio under its regular method of accounting for interest income. The amount of any positive inflation adjustment for a taxable year, which results from an increase in the inflation-adjusted principal amount of the bond, is treated as OID. The amount of a Portfolio's OID in a taxable year with respect to a bond will increase the Portfolio's taxable income for such year without a corresponding receipt of cash until the bond matures. As a result, a Portfolio may need to use other sources of cash to satisfy its distribution requirements for such year. The amount of any negative inflation adjustments, which result from a decrease in the inflation-adjusted principal amount of the bond, first reduces the amount of interest (including stated interest, OID, and market discount, if any) otherwise includible in a Portfolio's income with respect to the bond for the taxable year; any remaining negative adjustments will be either treated as ordinary loss or, in certain circumstances, carried forward to reduce the amount of interest income taken into account with respect to the bond in future taxable years.

Market Discount. Any market discount recognized on a market discount bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or below adjusted issue price if the bond was issued with original issue discount. Absent an election by a Portfolio to include the market discount in income as it accrues, the gain on the Portfolio's disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount. Where the income required to be recognized as a result of the market discount rules is not matched by a corresponding cash receipt by the Portfolio,

87

the Portfolio may be required to borrow money or dispose of securities to enable the Fund to make distributions to its shareholders in order to qualify for treatment as a regulated investment company and eliminate taxes at the Fund level, potentially resulting in additional taxable gain or loss to the Fund.

Derivatives and Other Complex Securities. A Fund, through its corresponding Portfolio, may invest in complex securities. These investments may be subject to numerous special and complex rules. These rules could affect whether gains and losses recognized by a Fund are treated as ordinary income or capital gain, accelerate the recognition of income to a Fund and/or defer a Fund's ability to recognize losses. In turn, these rules may affect the amount, timing or character of the income distributed to you by a Fund. You should consult your personal tax advisor regarding the application of these rules.

Master Limited Partnerships (SPDR SSGA Multi-Asset Real Return ETF only). Depreciation or other cost recovery deductions passed through to the Fund from the corresponding Portfolio's investments in MLPs in a given year will generally reduce the Fund's taxable income, but those deductions may be recaptured in the Fund's income in one or more subsequent years. When recognized and distributed, recapture income will generally be taxable to shareholders at the time of the distribution at ordinary income tax rates, even though the shareholders at that time might not have held Fund Shares at the time the deductions were taken by the Fund, and even though those shareholders will not have corresponding economic gain on their Fund Shares at the time of the recapture. In order to distribute recapture income or to fund redemption requests, the Fund's corresponding Portfolio may need to liquidate investments, which may lead to additional recapture income. The Portfolio's investments in MLPs and related entities treated as partnerships for U.S. federal income tax purposes potentially will result in distributions from the corresponding Fund being treated as return-of-capital distributions, which are not included in a shareholder's income but which reduce the shareholder's tax basis in his or her Fund Shares and therefore increase gains or decrease losses on dispositions of those Fund Shares. The Portfolio's investments in MLPs or related entities treated as partnerships for U.S. federal income tax purposes may also cause the corresponding Fund to recognize taxable income on investments in excess of the cash generated thereby, and may therefore require the Portfolio to sell investments, including when not otherwise advantageous to do so, in order for the Fund to satisfy the distribution requirements for treatment as a regulated investment company.

Foreign Currency Transactions. A Portfolio's transactions in foreign currencies, foreign currency denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and 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.

Foreign Income Taxes. Investment income received by a Portfolio from sources within foreign countries may be subject to foreign income taxes withheld at the source. The United States has entered into tax treaties with many foreign countries which may entitle a Portfolio to a reduced rate of such taxes or exemption from taxes on such income. It is impossible to determine the effective rate of foreign tax for a Fund in advance since the amount of the assets to be invested within various countries is not known. If more than 50% of the total assets of a Fund at the close of its taxable year consist of certain foreign stocks or securities, (generally including stocks or securities of foreign corporations held indirectly through a Portfolio), the Fund may elect to “pass through” to you certain foreign income taxes (including withholding taxes) paid by the Fund or the Portfolio. If a Fund in which you hold Fund Shares makes such an election, you will be considered to have received as an additional dividend your share of such foreign taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your federal income tax. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If a Fund does not so elect, the Fund will be entitled to claim a deduction for certain foreign taxes incurred by the Fund. Under certain circumstances, if a Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Fund Shares could be reduced 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.

Taxes on Exchange-Listed Share Sales. Any capital gain or loss realized upon a sale of Fund Shares is generally treated as long-term capital gain or loss if Fund Shares have been held for more than one year and as short-term capital gain or loss if Fund Shares have been held for one year or less, except that any capital loss on the sale of Fund Shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such Fund Shares.

88

Taxes on Creations and Redemptions of Creation Units. A person who exchanges securities for Creation Units generally will recognize a gain or loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the exchanger's aggregate basis in the securities surrendered plus any cash paid for the Creation Units. A person who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger's basis in the Creation Units and the aggregate market value of the securities and the amount of cash received. The Internal Revenue Service (the “IRS”), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Under current federal tax laws, any capital gain or loss realized upon a redemption (or creation) of Creation Units is generally treated as long-term capital gain or loss if the applicable Fund Shares (or securities surrendered) have been held for more than one year and as a short-term capital gain or loss if the applicable Fund Shares (or securities surrendered) have been held for one year or less.

If you create or redeem Creation Units, you will be sent a confirmation statement showing how many Fund Shares you purchased or sold and at what price.

Certain Tax-Exempt Investors. A Fund, if investing through a Portfolio in certain limited real estate investments and other publicly traded partnerships, may be required to pass through certain “excess inclusion income” and other income as “unrelated business taxable income” (“UBTI”). Prior to investing in a Fund, tax-exempt investors sensitive to UBTI should consult their tax advisors regarding this issue and IRS pronouncements addressing the treatment of such income in the hands of such investors.

Investments In Certain Foreign Corporations. A Portfolio may invest in foreign entities classified as passive foreign investment companies or “PFICs” under the Internal Revenue Code. PFIC investments are subject to complex rules that may under certain circumstances adversely affect a Fund. Accordingly, investors should consult their own tax advisors and carefully consider the tax consequences of PFIC investments by a Portfolio before making an investment in a corresponding Fund. Fund dividends attributable to dividends received from PFICs generally will not be treated as qualified dividend income. Additional information pertaining to the potential tax consequences to the Funds, and to the shareholders, from the Portfolios' potential investment in PFICs can be found in the SAI.

Non-U.S. Investors. Ordinary income dividends paid by a Fund to shareholders who are non-resident aliens or foreign entities will generally be subject to a 30% U.S. withholding tax (other than distributions reported by the Fund as interest-related dividends and short-term capital gain dividends), unless a lower treaty rate applies or unless such income is effectively connected with a U.S. trade or business. In general, a Fund may report interest-related dividends to the extent of its net income derived from U.S. source interest and a Fund may report short-term capital gain dividends to the extent its net short-term capital gain for the taxable year exceeds its net long-term capital loss.  Gains on the sale of Fund Shares and dividends that are, in each case, effectively connected with the conduct of a trade or business within the U.S. will generally be subject to U.S. federal net income taxation at regular income tax rates. Non-U.S. shareholders that own, directly or indirectly, more than 5% of a Fund's shares are urged to consult their own tax advisors concerning special tax rules that may apply to their investment.

Unless certain non-U.S. entities that hold Fund Shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to distributions payable to such entities and, after December 31, 2018, to redemption proceeds and certain capital gain dividends payable to such entities. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement.

Backup Withholding. A Fund will be required in certain cases to withhold (as “backup withholding”) on amounts payable to any shareholder who (1) has provided the Fund either an incorrect tax identification number or no number at all, (2) is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, (3) has failed to certify to the Fund that such shareholder is not subject to backup withholding, or (4) has not certified that

89

such shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is 28%. Backup withholding will not be applied to payments that have been subject to the 30% withholding tax on shareholders who are neither citizens nor permanent residents of the United States.

Other Tax Issues. A Fund may be subject to tax in certain states where the Fund does business (or is treated as doing business because of its investment in a Portfolio). Furthermore, in those states which have income tax laws, the tax treatment of the Funds and of Fund shareholders with respect to distributions by the Funds may differ from federal tax treatment.

The foregoing discussion summarizes some of the consequences under current federal income tax law of an investment in the Funds. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the Funds under all applicable tax laws.

General Information

The Trust was organized as a Massachusetts business trust on March 30, 2011. If shareholders of any Fund are required to vote on any matters, shareholders are entitled to one vote for each Fund Share they own. Annual meetings of shareholders will not be held except as required by the 1940 Act and other applicable law. See the SAI for more information concerning the Trust's form of organization.

Management and Organization

Each Fund, with the exception of the SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF,  is a separate, diversified series of the Trust, which is an open-end registered management investment company. Both SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF are separate, non-diversified series of the Trust.

For purposes of the 1940 Act, Fund Shares are issued by the respective series of the Trust and the acquisition of Fund Shares by investment companies is subject to the restrictions of Section 12(d)(1) of the 1940 Act.

The Trust has received exemptive relief from Section 12(d)(1) to allow registered investment companies to invest in certain Funds beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions as set forth in an SEC exemptive order issued to the Trust, including that such investment companies enter into an agreement with the Trust.

From time to time, a Fund may advertise yield and total return figures. Yield is a historical measure of dividend income, and total return is a measure of past dividend income (assuming that it has been reinvested) plus capital appreciation. Neither yield nor total return should be used to predict the future performance of a Fund.

Morgan, Lewis & Bockius LLP serves as counsel to the Trust, including the Funds. Ernst & Young LLP serves as the independent registered public accounting firm and will audit the Funds' financial statements annually.

Premium/Discount Information

Information showing the number of days the market price of a Fund's shares was greater than the Fund's NAV per Fund Share ( i.e. , at a premium) and the number of days it was less than the Fund's NAV per Fund Share ( i.e. , at a discount) for various time periods is available by visiting the Funds' website at https://www.spdrs.com .

Financial Highlights

These financial highlight tables are intended to help you understand each Fund's financial performance for the past five fiscal years or, if shorter, the period since each Fund's inception. Certain information reflects the performance results for a single Fund Share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in each Fund (assuming reinvestment of all dividends and distributions). This information has been audited by Ernst & Young LLP, the Trust's independent registered public accounting firm, whose report, along with each Fund's financial highlights and financial statements, is included in the annual report to shareholders, which is available upon request. The financial information included in these tables should be read in conjunction with the financial statements incorporated by reference in the SAI.

Portfolio Summary

State Street Disciplined Global Equity Portfolio

Investment Objective

The State Street Disciplined Global Equity Portfolio (the “Portfolio”) seeks to provide competitive long-term returns while maintaining low long-term volatility relative to the broad global equity market.

1

In seeking to identify stocks offering the potential for capital growth, the Adviser employs a proprietary quantitative process. The process evaluates the relative attractiveness of eligible securities based on the correlation of certain historical economic and financial factors (such as measures of growth potential, valuation, quality and investor sentiment), and other historical quantitative metrics. Additionally, the process may incorporate an element designed to evaluate the macroeconomic environment and prevailing market conditions. The process is intended to allow the Adviser to evaluate eligible securities and then rank eligible securities in the Portfolio's investment universe in the order of their attractiveness as potential Portfolio investments.

The Adviser also uses a quantitative analysis to determine the expected volatility of a stock's market price. Volatility is a statistical measurement of up and down fluctuations in the value of a security over time. Volatility may result in rapid and dramatic price swings. The Adviser seeks to favor securities with low exposure to market risk factors and low security-specific risk. In determining the exposure of a security to such risk factors, the Adviser may take into account, among other things, such considerations as a security's market capitalization, its price momentum, the security's valuation, the liquidity of the security, the degree to which the issuer is leveraged, and the issuer's growth prospects. The Adviser also implements risk constraints at the overall portfolio level by periodic testing of the Portfolio's composition against proprietary risk models, focusing on such factors as industry and sector exposures, portfolio diversification levels, market capitalization exposure, and geographic exposures.

Through these quantitative processes of security selection and portfolio diversification, the Adviser expects that the Portfolio will be subject to a relatively low level of absolute risk (as defined by statistical measures of volatility, such as standard deviation of returns) and that the Portfolio should exhibit relatively low volatility compared with the Index over the long term. The Adviser will make changes over time in the Portfolio's portfolio to reflect changes in the various risk factors described above. From time to time, the Adviser may make a qualitative judgment not to implement fully the results of the quantitative investment process if it believes that the process did not take into account all of the information relevant to a particular investment or the Portfolio's portfolio in the aggregate, or that a different investment might be more appropriate.

Although the Portfolio targets a low level of volatility in absolute terms and in comparison to the Index, there is no assurance that the Portfolio will achieve its target volatility, and the Portfolio may be subject to significant changes in value over short or longer timeframes. There also can be no assurance that the Portfolio will produce returns in excess of the Index.

The Portfolio will generally invest at least 40% of its assets in securities of issuers economically tied to countries other than the United States and will generally hold securities of issuers economically tied to at least three countries, including the United States. The Portfolio will generally consider an investment in an issuer to be tied to a particular country if (i) the issuer is organized in such country or maintains a principal place of business in such country; (ii) the issuer's securities are traded principally in such country; or (iii) during the issuer's most recent fiscal year, it derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in such country or has at least 50% of its assets in such country.

The Portfolio expects to invest primarily in common stocks. The Portfolio may purchase securities in their initial public offerings, and may hold securities that are restricted as to resale. The Portfolio may invest in other investment companies, including exchange-traded funds, to the extent permitted by applicable law (including those advised by the Adviser). The Portfolio may hold a portion of its assets in cash and cash instruments. While the Portfolio may invest in companies of any market capitalization, it expects to primarily invest in large capitalization companies.

The Portfolio may invest in derivatives, such as futures contracts, in order to gain broad equity market exposures pending investments of cash, or to reduce market exposures pending the sales of securities. The Portfolio reserves the right to enter into foreign currency futures and forward contracts to hedge currency risk, although the Adviser does not currently anticipate that such transactions will play any significant role of the investment process.

Principal Risks of Investing in the Portfolio

As with all investments, there are certain risks of investing in the Portfolio. Portfolio Shares will change in value, and you could lose money by investing in the Portfolio. An investment in the Portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Counterparty Risk: The Portfolio will be subject to credit risk with respect to the counterparties with which the Portfolio enters into derivatives contracts, repurchase agreements, reverse repurchase agreements, and other transactions. If a counterparty fails to meet its contractual obligations, the Portfolio 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 Portfolio. If the Portfolio 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.

2

Currency Hedging Risk: If the Portfolio enters into currency hedging transactions, any loss generated by those transactions generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the hedging transaction and the risk sought to be hedged. There can be no assurance that the Portfolio's hedging transactions will be effective.

Currency Risk: The value of the Portfolio'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 Portfolio's assets denominated in foreign currencies.

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, and the Portfolio 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 Portfolio'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 Portfolio anticipated by the Adviser.

Equity Investing Risk: The market prices of equity securities owned by the Portfolio 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 is less diversified across 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 more geographically-diversified 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.

Leveraging Risk: Use of leverage by the Portfolio may have the effect of increasing the volatility of the value of the Portfolio's portfolio, and may entail risk of loss in excess of the Portfolio's invested capital. To the extent the Portfolio uses leverage, the Portfolio's losses (and gains) may be greater than if the Portfolio had not used leverage.

Liquidity Risk: Lack of a ready market or restrictions on resale may limit the ability of the Portfolio to sell a security at an advantageous time or price or at all. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. Illiquidity of the Portfolio's holdings may limit the ability of the Portfolio to obtain cash to meet redemptions on a timely basis.  In addition, the Portfolio, due to limitations on investments in any illiquid securities 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 Portfolio 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 Portfolio to incur losses. There can be no assurance that the Adviser's investment techniques and decisions will produce the desired results.

Market Risk: The Portfolio's investments are subject to changes in general economic conditions, and 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, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Portfolio is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets.

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 Portfolio from the use of the models, or could result in incorrect outputs or in investment outcomes different from or opposite to those

3

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.

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, when the Portfolio 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 Portfolio. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market.

Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Portfolio expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

Unconstrained Sector Risk: The Portfolio 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 Portfolio's Shares to decrease, perhaps significantly.

Volatility Risk: Because the Portfolio seeks to exhibit relative low volatility and excess returns as compared to the Index over the long term, both its portfolio investments and its returns may differ, potentially greatly, from those of the Index. There can be no assurance that the Portfolio will in fact experience lower volatility than the Index nor can there be any assurance that the Portfolio will produce returns in excess of the benchmark. The application of the Adviser's active stock selection model may lead to a degree of added risk in exchange for the potential outperformance relative to the Index. Because the Portfolio is managed to limit volatility, it is likely that in periods of rapidly rising markets the Portfolio will experience less favorable returns than the Index.

Portfolio Performance

The Portfolio has not yet completed a full calendar year of investment operations and therefore does not have any performance history. Once the Portfolio has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Portfolio by showing the variability of the Portfolio's returns based on net assets and comparing the Portfolio's performance to a broad-based securities index. Updated performance information may be obtained by calling 1-866-787-2257.

Tax Information

The Portfolio's distributions are expected to be taxed as ordinary income, qualified dividend income and/or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. Any withdrawals made from such tax-advantaged arrangement may be taxable to you.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Portfolio Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser or its affiliates may pay the financial intermediary for certain activities related to the Portfolio, including educational training programs, conferences, the development of technology platforms and reporting systems, or other services related to the sale or promotion of the Portfolio. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Portfolio over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Additional Strategies Information

General. The Board of Trustees of the Trust (the “Board”) may change the Portfolio's investment objective, investment strategy and other policies without shareholder approval, except as otherwise indicated in this Prospectus or in the Statement of Additional Information (“SAI”).

Principal Strategies

Under normal circumstances, the Portfolio will invest at least 80% of its net assets (plus borrowings, if any, for investment purposes) in equity securities. The Portfolio will provide shareholders with at least sixty (60) days' notice prior to any change in its 80% policy. SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) seeks to select a portfolio of securities that it expects over the long term to exhibit low volatility both in absolute terms and in comparison with the MSCI World Index (the “Index”) and provide competitive returns as compared with the Index.

In seeking to identify stocks offering the potential for capital growth, the Adviser employs a proprietary quantitative process. The process evaluates the relative attractiveness of eligible securities based on the correlation of certain historical economic and financial factors (such as measures of growth potential, valuation, quality and investor sentiment), and other historical quantitative metrics. Additionally, the process may incorporate an element designed to evaluate the macroeconomic environment and prevailing market conditions. The process is intended to allow the Adviser to evaluate eligible securities and then rank eligible securities in the Portfolio's investment universe in the order of their attractiveness as potential Portfolio investments.

The Adviser also uses a quantitative analysis to determine the expected volatility of a stock's market price. Volatility is a statistical measurement of up and down fluctuations in the value of a security over time. Volatility may result in rapid and dramatic price swings. The Adviser seeks to favor securities with low exposure to market risk factors and low security-specific risk. In determining the exposure of a security to such risk factors, the Adviser may take into account, among other things, such considerations as a security's market capitalization, its price momentum, the security's valuation, the liquidity of the security, the degree to which the issuer is leveraged, and the issuer's growth prospects. The Adviser also implements risk constraints at the overall portfolio level by periodic testing of the Portfolio's composition against proprietary risk models, focusing on such factors as industry and sector exposures, portfolio diversification levels, market capitalization exposure, and geographic exposures.

Through these quantitative processes of security selection and portfolio diversification, the Adviser expects that the Portfolio will be subject to a relatively low level of absolute risk (as defined by statistical measures of volatility, such as standard deviation of returns) and that the Portfolio should exhibit relatively low volatility compared with the Index over the long term. The Adviser will make changes over time in the Portfolio's portfolio to reflect changes in the various risk factors described above. From time to time, the Adviser may make a qualitative judgment not to implement fully the results of the quantitative investment process if it believes that the process did not take into account all of the information relevant to a particular investment or the Portfolio's portfolio in the aggregate, or that a different investment might be more appropriate.

Although the Portfolio targets a low level of volatility in absolute terms and in comparison to the Index, there is no assurance that the Portfolio will achieve its target volatility, and the Portfolio may be subject to significant changes in value over short or longer timeframes. There also can be no assurance that the Portfolio will produce returns in excess of the Index.

The Portfolio will generally invest at least 40% of its assets in securities of issuers economically tied to countries other than the United States and will generally hold securities of issuers economically tied to at least three countries, including the United States. The Portfolio will generally consider an investment in an issuer to be tied to a particular country if (i) the issuer is organized in such country or maintains a principal place of business in such country; (ii) the issuer's securities are traded principally in such country; or (iii) during the issuer's most recent fiscal year, it derived at least 50% of its revenues or profits from goods produced or sold, investments made, or services performed in such country or has at least 50% of its assets in such country.

The Portfolio expects to invest primarily in common stocks. The Portfolio may also invest in other equity securities including depositary receipts having characteristics similar to common stocks, preferred stocks, convertible securities, and rights or warrants to buy common stocks. The Portfolio may purchase securities in their initial public offerings, and may hold securities that are restricted as to resale. The Portfolio may invest in other investment companies, including

6

exchange-traded funds, to the extent permitted by applicable law (including those advised by the Adviser). The Portfolio may hold a portion of its assets in cash and cash instruments. While the Portfolio may invest in companies of any market capitalization, it expects to primarily invest in large capitalization companies.

The Portfolio may invest in derivatives, such as futures contracts, in order to gain broad equity market exposures pending investments of cash, or to reduce market exposures pending the sales of securities. The Portfolio reserves the right to enter into foreign currency futures and forward contracts to hedge currency risk, although the Adviser does not currently anticipate that such transactions will play any significant role in the investment process.

Non-Principal Strategies

Temporary Defensive Positions. In response to actual or perceived adverse market, economic, political, or other conditions, the Portfolio 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. If the Portfolio invests for defensive purposes, it may not achieve its investment objective. In addition, the defensive strategy may not work as intended.

Borrowing Money . The Portfolio may borrow money from a bank as permitted by the Investment Company Act of 1940, as amended (the “1940 Act”) or other governing statute, by the Rules thereunder, or by the U.S. Securities and Exchange Commission (“SEC”) or other regulatory agency with authority over the Portfolio, but only for temporary or emergency purposes.

The 1940 Act presently allows a fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets (not including temporary borrowings not in excess of 5% of its total assets). The Portfolio may also invest in reverse repurchase agreements, which are considered borrowings under the 1940 Act. Although there is no percentage limit on Portfolio assets that can be used in connection with reverse repurchase agreements, the Portfolio does not expect to engage, under normal circumstances, in reverse repurchase agreements with respect to more than 33 1/3% of its total assets.

Additional Risk Information

The following section provides additional information regarding certain of the principal risks identified under “Principal Risks of Investing in the Portfolio” in the Portfolio Summary along with additional risk information.

Principal Risks

Convertible Securities Risk . Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer, depending on the terms of the securities) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. Convertible securities may be subordinate to other debt securities issued by the same issuer. Issuers of convertible securities are often not as strong financially as issuers with higher credit ratings. Convertible securities typically provide yields lower than comparable non-convertible securities. Their values may be more volatile than those of non-convertible securities, reflecting changes in the values of the securities into which they are convertible.

Counterparty Risk . The Portfolio will be subject to credit risk with respect to the counterparties with which the Portfolio enters into derivatives contracts and other transactions such as repurchase agreements or reverse repurchase agreements. The Portfolio'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 Portfolio may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Portfolio. The Portfolio 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 Portfolio 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. Contractual provisions and applicable law may prevent or delay the Portfolio from exercising its rights to terminate an investment or transaction with a financial institution experiencing financial difficulties, or to realize on collateral, and another institution may be

7

substituted for that financial institution without the consent of the Portfolio. If the credit rating of a derivatives counterparty declines, the Portfolio may nonetheless choose or be required to keep existing transactions in place with the counterparty, in which event the Portfolio would be subject to any increased credit risk associated with those transactions.

Currency Hedging Risk . If a derivative is used as a hedge against a position that the Portfolio holds, any gain generated by the derivative generally should be substantially offset by losses on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between a derivative and its reference asset. Furthermore, while the Portfolio may hedge against currency fluctuations, it is possible that a degree of currency exposure may remain even at the time a hedging transaction is implemented. As a result, changes in currency exchange rates may affect Portfolio returns even when the hedge works as intended. The effectiveness of the Portfolio's currency hedging strategy will also generally be affected by the volatility of both the securities that the Portfolio holds, and the volatility of the U.S. dollar relative to the currencies to be hedged. Increased volatility may reduce the effectiveness of the Portfolio's currency hedging strategy and may impact the costs associated with hedging transactions. The effectiveness of the Portfolio's currency hedging strategy and the costs associated with hedging transactions may also in general be affected by interest rates. Significant differences between U.S. dollar interest rates and foreign currency interest rates may further impact the effectiveness of the Portfolio's currency hedging strategy. There can be no assurance that the Portfolio's hedging transactions will be effective. The Portfolio's currency hedging activities will potentially increase or accelerate distributions to shareholders, increase distributions taxed to shareholders as ordinary income, result in the re-characterization of prior ordinary income distributions as return of capital, or generate losses that cannot be used to offset income or capital gain in subsequent years. The Portfolio will bear the costs associated with any such hedging transaction, regardless of any gain or loss experienced on the hedging transaction.

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 Portfolio'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 Portfolio's portfolio investments.

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, a 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.

8

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, and the Portfolio 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 Portfolio 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 Portfolio 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 Portfolio 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.

Equity Investing Risk . The market prices of equity securities owned by the Portfolio 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.

Forward Currency Contracts Risk . In a forward currency contract, the Portfolio agrees to buy in the future an amount in one currency in return for another currency, at an exchange rate determined at the time the contract is entered into. If currency exchange rates move against the Portfolio's position during the term of the contract, the Portfolio will lose money on the contract. There is no limit on the extent to which exchange rates may move against the Portfolio's position. The markets for certain currencies may at times become illiquid, and the Portfolio may be unable to enter into new forward contracts or to close out existing contracts. Forward currency contracts are entered into in the over-the-counter market, and the Portfolio's ability to profit from a contract will depend on the willingness and ability of its counterparty to perform its obligations under the contract. Use by the Portfolio of foreign currency forward contracts may give rise to investment leverage.

Futures Contract Risk; Other Exchange-Traded Derivatives Risk . The risk of loss relating to the use of futures contracts and other exchange-traded derivatives is potentially unlimited. The ability to establish and close out positions in futures contracts and other exchange-traded derivatives will be subject to the development and maintenance of a liquid secondary market. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract or other exchange-traded derivative or at any particular time. In the event no such market exists for a particular derivative, it might not be possible to effect closing transactions, and the Portfolio will be unable to terminate its exposure to the derivative. In using futures contracts and other exchange-traded derivatives, the Portfolio will be reliant on the ability of the Adviser to predict market and price movements correctly; the skills needed to use such derivatives successfully are different from those needed for traditional portfolio management. If the Portfolio uses futures contracts or other exchange-traded derivatives for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Portfolio's investments that are the subject of such hedge. The prices of futures and other exchange-traded derivatives, for a number of reasons, may not correlate perfectly with movements in the securities or index underlying them. For example, participants in the futures markets and in markets for other exchange-traded derivatives are subject to margin deposit requirements. Such requirements may cause investors to take actions with respect to their derivatives positions that they would not otherwise take. The margin requirements in the derivatives markets may be less onerous than margin requirements in the securities markets in

9

general, and as a result those markets may attract more speculators than the securities markets do. Increased participation by speculators in those markets may cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of general market trends by the Adviser still may not result in a successful derivatives activity over a very short time period. The risk of a position in a futures contract or other exchange-traded derivative may be very large compared to the relatively low level of margin the Portfolio is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Portfolio will incur brokerage fees in connection with its exchange-traded derivatives transactions. The Portfolio will typically be required to post margin with its futures commission merchant in connection with its transactions in futures contracts and other exchange-traded derivatives. In the event of an insolvency of the futures commission merchant, the Portfolio may not be able to recover all (or any) of the margin it has posted with the futures commission merchant, or to realize the value of any increase in the price of its positions. The Portfolio also may be delayed or prevented from recovering margin or other amounts deposited with a futures commission merchant or futures clearinghouse. The Commodity Futures Trading Commission (the “CFTC”) and the various exchanges have established limits referred to as “speculative position limits” on the maximum net long or net short positions that any person and certain affiliated entities may hold or control in a particular futures contract. Trading limits are imposed on the number of contracts that any person may trade on a particular trading day. An exchange may order the liquidation of positions found to be in violation of these limits and it may impose sanctions or restrictions. In addition, the Dodd-Frank Act requires the CFTC to establish speculative position limits on listed futures and economically equivalent over-the-counter (“OTC”) derivatives. Regulatory action taken by the CFTC to establish these additional position limits may adversely affect the market liquidity of the futures, options and economically equivalent derivatives in which the Portfolio may invest. It is possible that, as a result of such limits, the Portfolio's adviser will be precluded from taking positions in certain futures contracts or OTC derivatives as a result of positions held by other clients of the adviser or by the adviser or its affiliates themselves.

Futures contracts and other exchange-traded derivatives traded on markets outside the U.S. are not generally subject to regulation by the CFTC or other U.S. regulatory entities, including without limitation as to the execution, delivery, and clearing of transactions. U.S. regulators neither regulate the activities of a foreign exchange, nor have the power to compel enforcement of the rules of the foreign exchange or the laws of the foreign country in question. Margin and other payments made by the Portfolio may not be afforded the same protections as are afforded those payments in the U.S., including in connection with the insolvency of an executing or clearing broker or a clearinghouse or exchange. Certain foreign futures contracts and other exchange-traded derivatives may be less liquid and more volatile than U.S. contracts.

Geographic Focus Risk . The performance of a fund that is less diversified across 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 more geographically-diversified fund.

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.

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 Portfolio engages in transactions that have a leveraging effect on the Portfolio's investment portfolio, the value of the Portfolio 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 Portfolio would otherwise have and so magnifies the effect of any increase or decrease in the value of the Portfolio's underlying assets. The use of leverage is considered to be a speculative investment practice and may result in losses to the Portfolio. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The use of leverage may cause the Portfolio to liquidate positions when it may not be advantageous to do so to satisfy repayment, interest payment, or margin obligations or to meet asset segregation or coverage requirements.

10

Liquidity Risk. Liquidity risk is the risk that the Portfolio may not be able to dispose of securities or close out derivatives transactions readily at a favorable time or prices (or at all) or at prices approximating those at which the Portfolio 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 securities 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 Portfolio to value illiquid securities 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 securities may entail registration expenses and other transaction costs that are higher than those for liquid securities. The Portfolio 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 Portfolio.

Management Risk . The Portfolio 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 Portfolio 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 Portfolio 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 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 Portfolio'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 Economic and Monetary Union of the European Union, or any increased uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Portfolio's investments. 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 Portfolio. To the extent the Portfolio 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 Portfolio.

Market Risk . Market prices of investments held by the Portfolio will go up or down, sometimes rapidly or unpredictably. The Portfolio'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, 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 Portfolio could decline if the particular industries, sectors or companies in which the Portfolio 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.

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 Portfolio 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 Portfolio's investment program in particular can be uncertain. In recent periods, governmental and non-governmental issuers have defaulted on, or have been forced to restructure, their debts, and many other issuers have faced difficulties obtaining credit. These market conditions may continue, worsen or spread, including, without limitation, in Europe or Asia. 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. In recent periods, financial regulators, including

11

the U.S. Federal Reserve and the European Central Bank, have taken steps to maintain historically low interest rates, such as by purchasing bonds. Some governmental authorities have taken steps to devalue their currencies substantially or have taken other steps to counter actual or anticipated market or other developments. Steps by those regulators to implement, or to curtail or taper, such activities could have substantial negative effects on financial markets. The withdrawal of support, failure of efforts in response to a financial crisis, 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 Portfolio 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 Portfolio has sustained a loss (or reduced performance) related to such errors.

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 Portfolio'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 Portfolio'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 Portfolio's investments 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 Portfolio invests could cause the Portfolio's investments in that country to experience gains or losses.

Portfolio Turnover Risk . The Portfolio may engage in frequent trading of its portfolio securities. Portfolio turnover generally involves a number of direct and indirect costs and expenses to the Portfolio, 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 Portfolio's investment return, and the sale of securities by the Portfolio may result in the realization of taxable capital gains, including short-term capital gains.

Preferred Securities Risk . Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. Unlike debt securities, dividend payments on a preferred security typically must be declared by the issuer's board of directors. An issuer's board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on preferred securities at any time. Therefore, in the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare a dividend and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred

12

securities pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds - that is, as interest rates rise, the value of the preferred securities held by the Portfolio are likely to decline. Therefore, to the extent that the Portfolio invests a substantial portion of its assets in fixed rate preferred securities, rising interest rates may cause the value of the Portfolio's investments to decline significantly. In addition, because many preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Portfolio's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Portfolio's yield.

Rights or Warrants Risk . A warrant gives the holder a right to purchase, at any time during a specified period, a predetermined number of shares of common stock at a fixed price. Rights are similar to warrants but typically have a shorter duration and are issued by a company to existing stockholders to provide those holders the right to purchase additional shares of stock at a later date. Unlike a convertible debt security or preferred stock, a warrant or right does not pay fixed dividends. Warrants and rights may lack a liquid secondary market for resale. The prices of warrants and rights may fluctuate as a result of changes in the value of the underlying security or obligation or due to speculation in the market for the warrants or rights or other factors. Prices of warrants and rights do not necessarily move in tandem with the prices of their underlying securities; their prices may have significant volatility and it is possible that the Portfolio will lose its entire investment in a warrant or right. The Portfolio's failure to exercise a warrant or subscription right to purchase common shares in an issuer might result in the dilution of the Portfolio's interest in the issuing company.

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 Portfolio, limit the ability of the Portfolio to reinvest the proceeds of a sale of securities, hinder the ability of the Portfolio to lend its portfolio securities, and potentially subject the Portfolio to penalties for its failure to deliver to on-purchasers of securities whose delivery to the Portfolio was delayed. Delays in the settlement of securities purchased by the Portfolio may limit the ability of the Portfolio to sell those securities at times and prices it considers desirable, and may subject the Portfolio to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. The Portfolio 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.

Unconstrained Sector Risk . The Portfolio 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 Portfolio 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 Portfolio than if it had not focused its assets in that industry, market, or economic sector, which may increase the volatility of the Portfolio. Any such investment focus may also limit the liquidity of the Portfolio.

Volatility Risk. Because the Portfolio seeks to exhibit relative low volatility and excess returns as compared to the Index over the long term, both its portfolio investments and its returns may differ, potentially greatly, from those of the Index. There can be no assurance that the Portfolio will in fact experience lower volatility than the Index nor can there be any assurance that the Portfolio will produce returns in excess of the benchmark. The application of the Adviser's active stock selection model may lead to a degree of added risk in exchange for the potential outperformance relative to the Index. Because the Portfolio is managed to limit volatility, it is likely that in periods of rapidly rising markets the Portfolio will experience less favorable returns than the Index.

Non-Principal Risks

Conflicts of Interest Risk . An investment in the Portfolio may be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to the Portfolio, 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 Portfolio would compensate the Adviser and/or such affiliates. The Portfolio 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 Portfolio 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

13

most favorable available in the market generally or as favorable as the rates the Adviser makes available to other clients. Because of its financial interest, the Adviser may have an incentive to enter into transactions or arrangements on behalf of the Portfolio with itself or its affiliates in circumstances where it might not have done so in the absence of that interest.

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 Portfolio. 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 Portfolio 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 Portfolio. The Adviser or its affiliates, in connection with its other business activities, may acquire material non-public confidential information that may restrict the Adviser from purchasing securities or selling securities for itself or its clients (including the Portfolio) 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 Portfolio. The Portfolio 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 Portfolio) 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 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 Portfolio, the Adviser, a sub-adviser, or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect the Portfolio or its shareholders. For instance, cyber-attacks or technical malfunctions may interfere with the processing of shareholder or other transactions, affect the Portfolio's ability to calculate its NAV, cause the release of private shareholder information or confidential Portfolio information, impede trading, cause reputational damage, and subject the Portfolio 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 Portfolio assets and transactions, shareholder ownership of Portfolio Shares, and other data integral to the functioning of the Portfolio inaccessible or inaccurate or incomplete. The Portfolio may also incur substantial costs for cybersecurity risk management in order to prevent cyber incidents in the future. The Portfolio 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 Portfolio 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 Portfolio from cyber-attack. Similar types of cybersecurity risks or technical malfunctions also are present for issuers of securities in which the Portfolio invests, which could result in material adverse consequences for such issuers, and may cause the Portfolio's investment in such securities to lose value.

Master/Feeder Structure Risk : The Adviser also serves as investment adviser to a fund that invests substantially all of its assets in the Portfolio. Therefore, conflicts may arise as the Adviser fulfills its fiduciary responsibilities to the fund and the Portfolio.

Securities Lending Risk . The Portfolio may lend portfolio securities with a value of up to 40% 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, and the Portfolio will receive cash or other obligations as collateral. Any such loans must be continuously secured by collateral in cash or cash equivalents maintained on a current basis in an amount at least equal to the market value of the securities loaned by the Portfolio. In a loan transaction, as compensation for lending

14

its securities, the Portfolio will receive a portion of the dividends or interest accrued on the securities held as collateral or, in the case of cash collateral, a portion of the income from the investment of such cash. In addition, the Portfolio 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 Portfolio will call loans to vote proxies if a material issue affecting the investment is to be voted upon. Should the borrower of the securities fail financially, the Portfolio 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 Portfolio will also bear the risk of any decline in value of securities acquired with cash collateral. The Portfolio will attempt to minimize this risk by limiting the investment of cash collateral to high quality instruments of short maturity.

Management

Investment Adviser

SSGA FM, serves as the investment adviser to the Portfolio, and, subject to the supervision of the Board, is responsible for the investment management of the Portfolio. The Adviser provides an investment management program for the Portfolio and manages the investment of the Portfolio's assets. The Adviser is a wholly-owned subsidiary of State Street Global Advisors Inc., which is itself a wholly-owned subsidiary of State Street Corporation, and is registered with the SEC under the Investment Advisers Act of 1940, as amended. Prior to June 8, 2017, SSGA FM was a wholly-owned subsidiary of State Street Corporation. The Adviser and other affiliates of State Street Corporation make up State Street Global Advisors (“SSGA”). SSGA is one of the world's largest institutional money managers and the investment management arm of State Street Corporation. As of June 30, 2017, the Adviser managed approximately $438.78 billion in assets and SSGA managed approximately $2.61 trillion in assets. The Adviser's principal business address is State Street Financial Center, One Lincoln Street, Boston, Massachusetts 02111.

The Portfolio shares are offered exclusively to other investors (including without limitation, registered investment companies, private investment pools, bank collective funds, and separate accounts) that pay fees to SSGA FM or its affiliates. The fees paid by those investment vehicles to SSGA FM (or its affiliates) vary depending on a number of factors, including by way of example, the services provided, the risks borne by SSGA FM (or its affiliates), fee rates paid by competitive investment vehicles, and in some cases direct negotiation with investors.

For the services provided to the Portfolio under the Investment Advisory Agreement, the Portfolio pays the Adviser monthly fees of 0.25% based on a percentage of the Portfolio's average daily net assets as set forth in the Portfolio's Prospectus. For the fiscal year ended June 30, 2017, the Adviser did not receive any management fees after waivers. The Adviser has contractually agreed to waive its management fee and/or reimburse expenses in such an amount equal to the total annual Fund operation expenses until the later of April 30, 2019 or such time as the shares of the Portfolio cease to be the only investment security held by the State Street Disciplined Global Equity Fund. The waiver may be terminated prior to April 30, 2019 only by SSGA Active Trust's (the “Trust”) Board of Trustees. Additionally, the Adviser has contractually agreed to waive its management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for the Portfolio until October 31, 2018. This waiver and/or reimbursement does not provide for the recoupment by the Adviser of any amounts waived or reimbursed. This waiver and/or reimbursement may not be terminated prior to October 31, 2018 except with the approval of the Portfolio's Board of Trustees. The Adviser pays all expenses of the Portfolio other than the management fee, brokerage, taxes, interest, fees and expenses of the Independent Trustees (including any Trustee's counsel fees), litigation expenses and other extraordinary expenses. The Adviser has agreed to pay all costs associated with the organization of the Trust and the Portfolio.

A discussion regarding the Board's consideration of the Investment Advisory Agreement is provided in the Portfolio's Annual Report to Shareholders for the period ended June 30, 2017.

SSGA FM, as the investment adviser for the Portfolio, may hire one or more sub-advisers to oversee the day-to-day investment activities of the Portfolio. The sub-advisers are subject to oversight by the Adviser. The Adviser and the Trust have received an exemptive order from the SEC that permits the Adviser, with the approval of the Independent Trustees of the Trust, to retain and amend existing sub-advisory agreements with unaffiliated investment sub-advisers for the Portfolio without submitting the sub-advisory agreement to a vote of the Portfolio's and Fund's shareholders.

15

The Trust will notify shareholders in the event of any change in the identity of such sub-adviser or sub-advisers. The Adviser has ultimate responsibility for the investment performance of the Portfolio due to its responsibility to oversee each sub-adviser and recommend their hiring, termination and replacement. The Adviser is not required to disclose fees paid to any sub-adviser retained pursuant to the order.

Portfolio Managers.
The Adviser manages the Portfolio using a team of investment professionals. The team approach is used to create an environment that encourages the flow of investment ideas. 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.

The professionals primarily responsible for the day-to-day management of the Portfolio are Adel Daghmouri and Chee Ooi.

Adel Daghmouri is a Vice President of SSGA and the Adviser and a Senior Portfolio Manager in the Active Quantitative Equities Group. He focuses on managing global investment strategies, product development and quantitative research within developed markets. Prior to this, he was a founding member of the Quantitative Canadian Active Equity Team responsible for portfolio management across active, enhanced and market-neutral strategies. Since joining SSGA in 1998, Mr. Daghmouri has also worked as a portfolio manager in the Global Structured Products Group focusing on a broad range of international and domestic strategies. Mr. Daghmouri holds a Bachelor of Business Administration from Laval University and a Master of Science degree in Finance from HEC Montreal.

Chee Ooi is a Managing Director of SSGA and the Adviser and a Senior Portfolio Manager in the Active Quantitative Equities Group. He is responsible for research and portfolio management across the quantitative international active equity strategies. Currently based in Boston, Mr. Ooi joined SSGA in 2008. Prior to joining SSGA, he was a director and senior quantitative analyst in Citigroup's Global Quantitative Research Group in New York and started his career in finance at Salomon Brothers as a derivatives research analyst. Mr. Ooi has thirteen years of quantitative research and modeling experience on the sell-side. He has published papers in the Journal of Portfolio Management. He also pioneered the application of classification and regression tree technique in stock selection. Mr. Ooi holds a Bachelor of Science in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology.

Additional information about the portfolio managers' compensation, other accounts managed by the portfolio managers, and the portfolio managers' ownership of the Portfolio is available in the SAI.

Administrator, Sub-Administrator, Custodian and Transfer Agent. The Adviser serves as Administrator for the Portfolio. State Street, part of State Street Corporation, is the Sub-Administrator for the Portfolio and the Custodian for the Portfolio's assets, and serves as Transfer Agent to the Portfolio.

Distributor. State Street Global Advisors Funds Distributors, LLC serves as the Fund's distributor (“SSGA FD” or the “Distributor”) pursuant to the Distribution Agreement between SSGA FD and the Trust. The Distributor may enter into selected dealer agreements with other broker-dealers or other qualified financial institutions for the sale of Portfolio Shares. Prior to May 1, 2017, SSGA FD was known as State Street Global Markets, LLC.

Additional Information . The Board oversees generally the operations of the Portfolio and the Trust. The Trust enters into contractual arrangements with various parties, including among others the Portfolio's investment adviser, custodian, transfer agent, and accountants, who provide services to the Portfolio. 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 Portfolio that you should consider in determining whether to purchase Portfolio Shares. Neither this Prospectus nor the related SAI is intended, or should be read, to be or give rise to an agreement or contract between the Trust or the Portfolio 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.

Additional Purchase and Sale Information

The Portfolio's NAV is calculated on each day the New York Stock Exchange (the “NYSE”) is open for trading, at the close of regular trading on the NYSE. The NAV is based on the market value of the securities held in the Portfolio. As noted in this Prospectus, the Portfolio 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 Portfolio does not price its shares. Consequently, the NAV of Portfolio Shares may change on days when shareholders are not able to purchase or redeem Portfolio Shares. The Portfolio values each security pursuant to guidelines established by the Board of Trustees. Securities may be valued at fair value, as determined in good faith and pursuant to procedures approved by the Trust's Board of Trustees, under certain circumstances. For example, fair value pricing may be used when market quotations are not readily available or reliable, such as when (i) trading for a security is restricted; or (ii) a significant event, as determined by the Valuation Committee, that may affect the value of one or more securities held by the Portfolio occurs after the close of a related exchange but before the determination of the Portfolio's NAV. Attempts to determine the fair value of securities introduce an element of subjectivity to the pricing of securities. As a result, the price of a security determined through fair valuation techniques may differ from the price quoted or published by other sources and may not accurately reflect the price the Portfolio would have received had it sold the investment. To the extent that the Portfolio invests in the shares of other registered open-end investment companies that are not traded on an exchange (i.e. mutual funds), such shares are valued at their published net asset values 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. Because foreign securities held by the Portfolio sometimes trade on days when the Portfolio is not priced, the value of the Portfolio's portfolio may change on days when Portfolio Shares cannot be purchased or redeemed. Debt obligation securities maturing within 60 days of the valuation date are valued at amortized cost.

Purchasing Shares . Generally, shares of the Portfolio may be purchased only by or on behalf of other registered investment companies or private clients for which the Adviser or an affiliate serves as investment adviser (or in a similar capacity). The price for Portfolio shares is the NAV per share. Orders received in good form (a purchase order is in good form if it meets the requirements implemented from time to time by the Portfolio or its Transfer Agent, and for new accounts includes submission of a completed and signed application and all documentation necessary to open an account) will be priced at the NAV next calculated after the order is accepted by the Portfolio.

There is no minimum initial investment in the Portfolio and there is no minimum subsequent investment. The Portfolio reserves the right to cease accepting investments at any time or to reject any purchase order.

In accordance with certain federal regulations, the Trust is required to obtain, verify and record information that identifies each entity that applies to open an account. For this reason, when you open (or change ownership of) an account, the Trust will request certain information, including your name, residential/business address, date of birth (for individuals) and taxpayer identification number or other government identification number and other information that will allow us to identify you which will be used to verify your identity. The Trust may also request to review other identification documents such as driver license, passport or documents showing the existence of the business entity. If you do not provide sufficient information to verify your identity, the Trust will not open an account for you. As required by law, the Trust may employ various procedures, such as comparing your information to fraud databases or requesting additional information and documentation from you, to ensure that the information supplied by you is correct. The Trust reserves the right to reject any purchase order for any reason, including failure to provide the Trust with information necessary to confirm your identity as required by law.

Redeeming Shares . An investor may redeem all or any portion of its investment at the NAV next determined after it submits a redemption request, in proper form, to the Portfolio. The Portfolio will pay the proceeds of the redemption either in Federal funds or in securities at the discretion of the Adviser, normally on the next Portfolio business day after the redemption, but in any event no more than seven days after the redemption. The right of any investor to receive payment with respect to any redemption may be suspended or the payment of the redemption proceeds postponed during any period in which the NYSE is closed (other than weekends or holidays) or trading on the NYSE is restricted or, to the extent otherwise permitted by the 1940 Act, as amended, if an emergency exists.

Under normal circumstances, the Portfolio expects to meet redemption requests by using cash or cash equivalents in its portfolio and/or selling portfolio assets to generate cash. The Portfolio also may pay redemption proceeds using cash obtained through borrowing arrangements.

17

The Portfolio may pay all or a portion of redemption proceeds with securities (for example, if the Portfolio reasonably believes that cash redemptions may have a substantial impact on the Portfolio and its remaining shareholders). When meeting redemption requests with securities, the Portfolio will normally pay with a pro rata portion of portfolio securities, but may pay in individual securities or representative baskets of equal value. There may be transaction costs to dispose of the securities shareholders receive as redemption proceeds, and such shareholders may receive less for them than the price at which they were valued for purposes of the redemption. Shareholders will be subject to the market risks associated with such securities until such time as they choose to dispose of the security and there may be tax consequences.

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

Distributions

Dividends and Capital Gains. As a Portfolio shareholder, you are entitled to your share of the Portfolio's income and net realized gains on its investments. The Portfolio pays out substantially all of its net earnings to its shareholders as “distributions.”

The Portfolio's income may include dividends from stock investments, interest from debt securities and, if participating, securities lending income. These amounts, net of expenses and taxes (if applicable), are passed along to Portfolio shareholders as “income dividend distributions.” The Portfolio will generally realize short-term capital gains or losses whenever it sells or exchanges assets held for one year or less. Net short-term capital gains will generally be treated as ordinary income when distributed to shareholders. The Portfolio will generally realize long-term capital gains or losses whenever it sells or exchanges assets held for more than one year. Net capital gains (the excess of the Portfolio's net long-term capital gains over its net short-term capital losses) are distributed to shareholders as “capital gain distributions.”

Income dividend distributions, if any, are generally distributed by the Portfolio to shareholders annually, but may vary significantly from period to period.

Net capital gains for the Portfolio are distributed at least annually. Dividends may be declared and paid more frequently or at any other times to comply with the distribution requirements of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”).

Dividends and capital gains distributions will be automatically reinvested in additional Portfolio Shares unless you instruct otherwise. Dividends which are reinvested will nevertheless be taxable to the same extent as if such dividends had not been reinvested.

Portfolio Holdings Disclosure

The Portfolio's portfolio holdings disclosure policy is described in the SAI. In addition, the identities and quantities of the securities held by the Portfolio are disclosed on the Portfolio's website.

Additional Tax Information

The following discussion is a summary of some important U.S. federal tax considerations generally applicable to an investment in the Portfolio. Your investment in the Portfolio 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.

Taxes on Distributions. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in the Portfolio. The income dividends and short-term capital gains distributions you receive from the Portfolio will be taxed as either ordinary income or qualified dividend income. Subject to certain limitations, dividends that are reported by the Portfolio as qualified dividend income are taxable to noncorporate shareholders at rates of up to 20%. Any distributions of the Portfolio's net capital gains are taxable as long-term

18

capital gain regardless of how long you have owned Portfolio Shares. Long-term capital gains are generally taxed to noncorporate shareholders at rates of up to 20%. Distributions in excess of the Portfolio's current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the Portfolio's shares, and, in general, as capital gain thereafter.

In general, dividends may be reported by the Portfolio as qualified dividend income if they are attributable to qualified dividend income received by the Portfolio, which, in general, includes dividend income from taxable U.S. corporations and certain foreign corporations ( i.e ., certain foreign corporations incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, and certain other foreign corporations if the stock with respect to which the dividend is paid is readily tradable on an established securities market in the United States), provided that the Portfolio satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. A dividend generally will not be treated as qualified dividend income if the dividend is received with respect to any share of stock held by the Portfolio for fewer than 61 days during the 121-day period beginning at 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, for fewer than 91 days during the 181-day period beginning 90 days before such date. These holding period requirements will also apply to your ownership of Portfolio Shares. Holding periods may be suspended for these purposes for stock that is hedged. Additionally, income derived in connection with the Portfolio's securities lending activities will not be treated as qualified dividend income.

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% Medicare contribution tax on all or a portion of their “net investment income,” which includes taxable interest, dividends and certain capital gains (generally including capital gain distributions and capital gains realized upon the sale of Portfolio Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

If you lend your Portfolio Shares pursuant to securities lending arrangements you may lose the ability to treat Portfolio dividends (paid while the Portfolio Shares are held by the borrower) as qualified dividend income.  You should consult your financial intermediary or tax advisor to discuss your particular circumstances.

Distributions paid in January, but declared by the Portfolio in October, November or December of the previous year, payable to shareholders of record in such a month, may be taxable to you in the calendar year in which they were declared. The Portfolio will inform you of the amount of your ordinary income dividends, qualified dividend income and capital gain distributions shortly after the close of each calendar year.

A distribution will reduce the Portfolio's net asset value per Portfolio Share and may be taxable to you as ordinary income or capital gain even though, from an investment standpoint, the distribution may constitute a return of capital.

Derivatives and Other Complex Securities. The Portfolio may invest in complex securities. These investments may be subject to numerous special and complex rules. These rules could affect whether gains and losses recognized by the Portfolio are treated as ordinary income or capital gain, accelerate the recognition of income to the Portfolio and/or defer the Portfolio's ability to recognize losses. In turn, these rules may affect the amount, timing or character of the income distributed to you by the Portfolio. You should consult your personal tax advisor regarding the application of these rules.

Foreign Currency Transactions. The Portfolio's transactions in foreign currencies, foreign currency denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and 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.

Foreign Income Taxes. Investment income received by the Portfolio from sources within foreign countries may be subject to foreign income taxes withheld at the source. The United States has entered into tax treaties with many foreign countries which may entitle the Portfolio to a reduced rate of such taxes or exemption from taxes on such income. It is impossible to determine the effective rate of foreign tax for the Portfolio in advance since the amount of the assets to be invested within various countries is not known. If more than 50% of the total assets of the Portfolio at the close of its taxable year consist of certain foreign stocks or securities, the Portfolio may elect to “pass through” to you certain foreign income taxes (including withholding taxes) paid by the Portfolio. If the Portfolio makes such an election, you will be considered to have received as an additional dividend your share of such foreign taxes, but you

19

may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your federal income tax. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If the Portfolio does not so elect, the Portfolio will be entitled to claim a deduction for certain foreign taxes incurred by the Portfolio. Under certain circumstances, if the Portfolio receives a refund of foreign taxes paid in respect of a prior year, the value of Portfolio Shares could be reduced or any foreign tax credits or deductions passed through to shareholders in respect of the Portfolio's foreign taxes for the current year could be reduced.

Taxes on Portfolio Share Redemptions. Any capital gain or loss realized upon a redemption of Portfolio Shares is generally treated as long-term capital gain or loss if the Portfolio Shares have been held for more than one year and as short-term capital gain or loss if the Portfolio Shares have been held for one year or less, except that any capital loss on the redemption of Portfolio Shares held for six months or less is treated as long-term capital loss to the extent of capital gain dividends paid (or treated as paid) with respect to such Portfolio Shares.

Certain Tax-Exempt Investors. The Portfolio, if investing through a Portfolio in certain limited real estate investments and other publicly traded partnerships, may be required to pass through certain “excess inclusion income” and other income as “unrelated business taxable income” (“UBTI”). Prior to investing in the Portfolio, tax-exempt investors sensitive to UBTI should consult their tax advisors regarding this issue and IRS pronouncements addressing the treatment of such income in the hands of such investors.

Non-U.S. Investors. Ordinary income dividends paid by the Portfolio to shareholders who are non-resident aliens or foreign entities will generally be subject to a 30% U.S. withholding tax (other than distributions reported by the Portfolio as interest-related dividends and short-term capital gain dividends), unless a lower treaty rate applies or unless such income is effectively connected with a U.S. trade or business. In general, the Portfolio may report interest-related dividends to the extent of its net income derived from U.S. source interest and the Portfolio may report short-term capital gain dividends to the extent its net short-term capital gain for the taxable year exceeds its net long-term capital loss. Gains on the sale of Portfolio Shares and dividends that are, in each case, effectively connected with the conduct of a trade or business within the U.S. will generally be subject to U.S. federal net income taxation at regular income tax rates. Non-U.S. shareholders that own, directly or indirectly, more than 5% of the Portfolio's shares are urged to consult their own tax advisors concerning special tax rules that may apply to their investment.

Unless certain non-U.S. entities that hold Portfolio Shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to distributions payable to such entities and, after December 31, 2018, to redemption proceeds and certain capital gain dividends payable to such entities. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement.

Backup Withholding. The Portfolio will be required in certain cases to withhold (as “backup withholding”) on amounts payable to any shareholder who (1) has provided the Portfolio either an incorrect tax identification number or no number at all, (2) is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, (3) has failed to certify to the Portfolio that such shareholder is not subject to backup withholding, or (4) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is 28%. Backup withholding will not be applied to payments that have been subject to the 30% withholding tax on shareholders who are neither citizens nor permanent residents of the United States.

Other Tax Issues. The Portfolio may be subject to tax in certain states where the Portfolio does business (or is treated as doing business as a result of its investments). Furthermore, in those states which have income tax laws, the tax treatment of the Portfolio and of Portfolio shareholders with respect to distributions by the Portfolio may differ from federal tax treatment.

The foregoing discussion summarizes some of the consequences under current federal income tax law of an investment in the Portfolio. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the Portfolio under all applicable tax laws.

General Information

The Trust was organized as a Massachusetts business trust on March 30, 2011. If shareholders of the Portfolio are required to vote on any matters, shareholders are entitled to one vote for each Portfolio Share they own. Annual meetings of shareholders will not be held except as required by the 1940 Act and other applicable law. See the SAI for more information concerning the Trust's form of organization.

From time to time, the Portfolio may advertise yield and total return figures. Yield is a historical measure of dividend income, and total return is a measure of past dividend income (assuming that it has been reinvested) plus capital appreciation. Neither yield nor total return should be used to predict the future performance of the Portfolio.

Morgan, Lewis & Bockius LLP serves as counsel to the Trust, including the Portfolio. Ernst & Young LLP serves as the independent registered public accounting firm and will audit the Portfolio's financial statements annually.

Financial Highlights

These financial highlight tables are intended to help you understand the Portfolio's financial performance since its inception. Certain information reflects the performance results for a single Portfolio Share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Portfolio (assuming reinvestment of all dividends and distributions). This information has been audited by Ernst & Young LLP, the Trust's independent registered public accounting firm, whose report, along with the Portfolio's financial highlights and financial statements, is included in the annual report to shareholders, which is available upon request. The financial information included in these tables should be read in conjunction with the financial statements incorporated by reference in the SAI.

SPDR ^® DoubleLine ^® Emerging Markets Fixed Income ETF

Investment Objective

The SPDR DoubleLine Emerging Markets Fixed Income ETF (the “Fund”) seeks to provide high total return from current income and capital appreciation.

1

institutions, or government entities in emerging market countries; corporate or government bonds; sovereign debt; structured securities; foreign currency transactions; certain derivatives; preferred securities; zero coupon bonds; credit-linked notes; pass through notes; bank loans; and perpetual maturity bonds. Fixed income securities may have fixed or variable interest rates and any maturity. The Fund may also invest in exchange-traded foreign equity securities and depositary receipts. The Fund will generally invest in securities and/or instruments from at least five emerging market countries, with no more than 20% allocated to a single country. An “emerging market country” is a country that, at the time the Fund invests in the related security or instrument, is classified as an emerging or developing economy by any supranational organization such as the World Bank or the United Nations, or related entities, or is considered an emerging market country for purposes of constructing a major emerging market securities index. A security or instrument is considered to be from an emerging market country if the issuer or guarantor of the security or instrument is either domiciled in an emerging market country or derives a majority of its cash flow or revenue from an emerging market country. Certain fixed income securities held by the Fund may not be registered under the Securities Act of 1933, as amended (“1933 Act”), including securities that are typically purchased pursuant to Rule 144A or Regulation S promulgated under the 1933 Act. These securities are expected to be liquid.

The Fund may invest in fixed income securities of any credit quality, but seeks to invest no more than 20%, at the time of investment, in fixed income securities that are unrated, rated BB+ or lower by Standard & Poor's Rating Service or Ba1 or lower by Moody's Investors Service, Inc. or the equivalent by any other nationally recognized statistical rating organization. Corporate bonds and certain other fixed income securities rated below investment-grade, or such instruments that are unrated and are determined by the Sub-Adviser to be of comparable quality, are high yield, high risk bonds, commonly known as junk bonds. The Fund may invest in hybrid securities relating to emerging market countries. A hybrid security may be created by combining an income-producing debt security and the right to receive payment based on the change in the price of an equity security.

The Fund may conduct foreign currency transactions on a spot ( i.e. , cash) or forward basis ( i.e. , by entering into forward contracts to purchase or sell foreign currencies). The Fund may also invest in the following derivatives: foreign currency futures; credit default swaps; and options, swaps, futures, and forward contracts on securities. These practices may be used to hedge the Fund's portfolio ( e.g. , to hedge against currency fluctuations), as well as for investment purposes ( e.g. , to gain exposure to certain issuers or emerging markets); however, such practices sometimes may reduce returns or increase volatility. All such derivatives will be exchange traded or centrally cleared.

In allocating investments among various emerging market countries, the Sub-Adviser attempts to analyze internal political, market and economic factors. These factors may include public finances, monetary policy, external accounts, financial markets, foreign investment regulations, stability of exchange rate policy, and labor conditions.

In managing the Fund's investments, under normal market conditions, the Sub-Adviser intends to seek to construct an investment portfolio with a weighted average effective duration of no less than two years and no more than eight years. Duration is a measure of the expected life of a fixed income instrument that is used to determine the sensitivity of a security's price to changes in interest rates. Effective duration is a measure of the Fund's portfolio duration adjusted for the anticipated effect of interest rate changes on bond and mortgage pre-payment rates. The effective duration of the Fund's investment portfolio may vary materially from its target, from time to time, and there is no assurance that the effective duration of the Fund's investment portfolio will not exceed its target. The Fund may invest without limit in investments denominated in any currency, but expects to invest a portion of its assets in investments denominated in the U.S. dollar. Securities held by the Fund may be sold at any time. By way of example, sales may occur when the Sub-Adviser perceives deterioration in the credit fundamentals of the issuer, when the Sub-Adviser believes there are negative macro geo-political considerations that may affect the issuer, when the Sub-Adviser determines to take advantage of a better investment opportunity, or the individual security has reached the Sub-Adviser's sell target.

Principal Risks of Investing in the Fund

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Bank Loan Risk: The Fund may invest in secured and unsecured participations in bank loans and assignments of such loans. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest which will expose the Fund to the credit risk of both the financial institution and the underlying borrower. The market for bank loans may not be highly liquid and the Fund may have difficulty selling them. The Fund may also experience settlement delays with respect to bank loan trades. Participations by the Fund in a lender's portion of a bank loan typically will result in the Fund having a contractual relationship only with such lender, not with the

2

borrower. The Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling a loan participation and only upon receipt by such lender of such payments from the borrower. In connection with purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other lenders through set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund may assume the credit risk of both the borrower and the lender selling the participation. Further, loans held by the Fund may not be considered securities and, therefore, purchasers, such as the Fund, may not be entitled to rely on the strong anti-fraud protections of the federal securities laws.

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.

Currency Hedging Risk: If the Fund enters into currency hedging transactions, any loss generated by those transactions generally should be substantially offset by gains on the hedged investment, and vice versa. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. Hedges are sometimes subject to imperfect matching between the hedging transaction and the risk sought to be hedged. There can be no assurance that the Fund's hedging transactions will be effective.

Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, increases 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; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. 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. The U.S. is experiencing historically low interest rate levels. However, economic recovery and the tapering of the Federal Reserve Board's quantitative easing program increase the likelihood that interest rates will rise in the future. 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. 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.

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.

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, and 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 Sub-Adviser or may not have the effect on the Fund anticipated by the Sub-Adviser.

3

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, 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.

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. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Geographic Focus Risk: The performance of a fund that is less diversified across 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 more geographically-diversified fund.

Latin America: Latin American economies are generally considered emerging markets and are generally characterized by high interest, inflation, and unemployment rates. Currency devaluations in any one Latin American country can have a significant effect on the entire Latin American region. Because commodities such as oil and gas, minerals, and metals represent a significant percentage of the region's exports, the economies of Latin American countries are particularly sensitive to fluctuations in commodity prices. A relatively small number of Latin American companies represents a large portion of Latin America's total market and thus may be more sensitive to adverse political or economic circumstances and market movements.

High Yield Securities Risk: Securities rated below investment-grade, commonly referred to as “junk bonds,” include bonds that are rated Ba1/BB+/BB+ or below by Moody's Investors Service, Inc., Fitch Inc., or Standard & Poor's Financial Services, LLC, respectively, or unrated securities considered to be of equivalent quality by the Sub-Adviser, and may involve greater risks than securities in higher rating categories. Such bonds are regarded as speculative in nature, involve greater risk of default by the issuing entity and may be subject to greater market fluctuations than higher rated debt securities. They are usually issued by entities without long track records of sales and earnings, or by entities with questionable credit strength. The retail secondary market for these “junk bonds” may be less liquid than that of higher rated securities and adverse conditions could make it difficult at times to sell certain securities or could result in lower prices than those used in calculating the Fund's net asset

4

value. High yield securities also may present greater credit risk because such securities may be issued in connection with corporate restructuring by highly leveraged issuers or may not be current in the payment of interest or principal or in default.

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.

Leveraging Risk: Use of leverage by the Fund may have the effect of increasing the volatility of the value of the Fund's portfolio, and may entail risk of loss in excess of the Fund's invested capital. To the extent the Fund uses leverage, the Fund's losses (and gains) may be greater than if the Fund had not used leverage.

Liquidity Risk: Lack of a ready market 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 securities 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 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 securities 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 Sub-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 Sub-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, and 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, 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.

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, when 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. Certain countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions.  Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

Pass-Through Securities Risk: Pass-through securities are debt obligations backed by a pool of assets, such as mortgages. In addition to the risks associated with investing in debt securities generally, pass-through securities are subject to changes in the payment patterns of borrowers of the underlying debt. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in the Fund having to reinvest the proceeds in lower yielding securities, effectively reducing the Fund's income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which pass-through securities are paid off could be extended, reducing the Fund's cash available for reinvestment in higher yielding securities.

5

Perpetual Bond Risk: Perpetual bonds offer a fixed return with no maturity date. Because they never mature, perpetual bonds can be more volatile than other types of bonds that have a maturity date and may have heightened sensitivity to changes in interest rates. If market interest rates rise significantly, the interest rate paid by a perpetual bond may be much lower than the prevailing interest rate.  Perpetual bonds are also subject to credit risk with respect to the issuer.  In addition, because perpetual bonds may be callable after a set period of time, there is the risk that the issuer may recall the bond.

Portfolio Turnover Risk: Frequent purchases and sales of portfolio securities may result in higher Fund expenses and may result in more significant distributions of short-term capital gains to investors, which are taxed as ordinary income.

Preferred Securities Risk: Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. Dividend payments on a preferred security typically must be declared by the issuer's board of directors. In the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the reduced likelihood that the issuer's board of directors will declare a dividend and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the preferred securities held by the Fund are likely to decline. In addition, because many preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Fund's yield.

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.

Sovereign Debt Obligations Risk: Investments in debt securities issued by governments or by government agencies and instrumentalities involve the risk that the governmental entities responsible for repayment may be unable or unwilling to pay interest and repay principal when due. Many sovereign debt obligations may be rated below investment-grade (“junk” bonds). Any restructuring of a sovereign debt obligation held by the Fund will likely have a significant adverse effect on the value of the obligation. In the event of default of sovereign debt, the Fund may be unable to pursue legal action against the sovereign issuer or to realize on collateral securing the debt.

Structured Securities Risk: Structured securities generally include privately-issued and publicly-issued structured securities, including certain publicly-issued structured securities that are not agency securities. An investment in a structured product may decline in value due to changes in the underlying instruments on which the product is based. The cash flow or rate of return on a structured investment may be determined by applying a multiplier to the rate of total return on the underlying investments or referenced indicator. Application of a multiplier is comparable to the use of financial leverage, a speculative technique. Holders of structured products indirectly bear risks associated with the underlying investments, index or reference obligation, and are subject to counterparty risk. Structured products are generally privately offered and sold, and thus, are not registered under the securities laws. Certain structured products may be thinly traded or have a limited trading market and may have the effect of increasing the Fund's illiquidity to the extent that the Fund, at a particular point in time, may be unable to find qualified buyers for these securities. Structured notes are derivative securities for which the amount of principal repayment and/or interest payments is based on the movement of one or more “factors.” Investments in structured notes, including credit-linked notes, involve risks including interest rate risk, credit risk and market risk. Where the Fund's investments in structured notes are based upon the movement of one or more factors, depending on the factor used and the use of multipliers or deflators, changes in interest rates and movement of the factor may cause significant price fluctuations.

6

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.

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.

Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on such securities will typically readjust downward resulting in a lower yield. In addition, investment in derivative variable rate securities, such as inverse floaters, whose rates vary inversely with market rates of interest, or range floaters or capped floaters, whose rates are subject to periodic or lifetime caps, or in securities that pay a rate of interest determined by applying a multiple to the variable rate involves special risks as compared to investment in a fixed-rate security and may involve leverage. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities.

Zero-Coupon Bond Risk: Zero-coupon bonds usually trade at a deep discount from their face or par values and are subject to greater market value fluctuations from changing interest rates than debt obligations of comparable maturities that make current distributions of interest.

Fund Performance

The Fund has not yet completed a full calendar year of investment operations and therefore does not have any performance history. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's returns based on net assets and comparing the Fund's performance to a broad-based securities index. When available, the Fund will make updated performance information available by calling 1-866-787-2257 or visiting the Fund's website: https://www.spdrs.com .

Purchase and Sale Information

The Fund will issue (or redeem) Fund Shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of 50,000 Fund Shares known as “Creation Units.” Creation Unit transactions are typically conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities and/or cash. Creation Unit transactions may be conducted in exchange for cash only, which may cause the Fund to recognize capital gains and to pay out higher annual capital gain distributions to shareholders than if such transactions had been conducted in-kind.

Individual Fund Shares may only be purchased and sold on the BATS Exchange, Inc. (the “Exchange”), other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at net asset value (“NAV”), Fund Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

Tax Information

The Fund's distributions are expected to be taxed as ordinary income, qualified dividend income and/or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. Any withdrawals made from such tax-advantaged arrangement may be taxable to you.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser or its affiliates may pay the financial intermediary for certain activities related to the Fund, including educational training programs, conferences, the development of technology platforms and reporting systems, or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
