INVESTMENT POLICIES

Each Fund may directly, or indirectly through investment in an exchange traded product (“ETP”), invest in any of the instruments or engage in any of the investment practices described below if such investment or activity is consistent with the Fund’s investment objective and permitted by the Fund’s stated investment policies.

Each Fund may invest in the following types of investments, consistent with its investment strategies and objective. Please see a Fund’s Prospectus for additional information regarding its principal investment strategies.

DIVERSIFICATION STATUS

Each Fund (except the SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF) is classified as a “diversified” investment company under the 1940 Act. Under the 1940 Act, a diversified investment company, as to 75% of its total assets, may not purchase securities of any issuer (other than securities issued or guaranteed by the U.S. government, its agents or instrumentalities or securities of other investment companies) if, as a result, more than 5% of its total assets would be invested in the securities of such issuer, or more than 10% of the issuer’s outstanding voting securities would be held by the investment company.

3

The SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF are each classified as a non-diversified investment company under the 1940 Act. A “non-diversified” classification means that a Fund is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. This means that a Fund may invest a greater portion of its assets in the securities of a single issuer than a diversified fund. This may have an adverse effect on a Fund’s performance or subject a Fund’s Shares to greater price volatility than more diversified investment companies.

Each Fund intends to maintain a level of diversification and otherwise conduct their operations so as to enable each Fund to qualify for treatment as a “regulated investment company” for purposes of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), and to relieve each Fund of any liability for federal income tax to the extent that its earnings are distributed to shareholders. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Funds and may make it less likely that the Funds will meet their investment objectives.

ASSET-BACKED AND MORTGAGE-BACKED SECURITIES

Mortgage-backed securities, including Collateralized Mortgage Obligations (“CMOs”) and certain stripped mortgage-backed securities, represent a participation in, or are secured by, mortgage loans. Asset-backed securities are structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property and receivables from credit card agreements. The cash flow generated by the underlying assets is applied to make required payments on the securities and to pay related administrative expenses. The amount of residual cash flow resulting from a particular issue of asset-backed or mortgage-backed securities depends on, among other things, the characteristics of the underlying assets, the coupon rates on the securities, prevailing interest rates, the amount of administrative expenses and the actual prepayment experience on the underlying assets. Each Fund may invest in any such instruments or variations as may be developed, to the extent consistent with its investment objective and policies and applicable regulatory requirements. In general, the collateral supporting asset-backed securities is of a shorter maturity than mortgage loans and is likely to experience substantial prepayments.

Mortgage-backed securities have yield and maturity characteristics corresponding to the underlying assets. Unlike traditional debt securities, which may pay a fixed rate of interest until maturity, when the entire principal amount comes due, payments on certain mortgage-backed securities include both interest and a partial repayment of principal. Besides the scheduled repayment of principal, repayments of principal may result from the voluntary prepayment, refinancing or foreclosure of the underlying mortgage loans. If property owners make unscheduled prepayments of their mortgage loans, these prepayments will result in early payment of the applicable mortgage-backed securities. In that event, a Fund may be unable to invest the proceeds from the early payment of the mortgage-backed securities in an investment that provides as high a yield as the mortgage-backed securities. Consequently, early payment associated with mortgage-backed securities may cause these securities to experience significantly greater price and yield volatility than that experienced by traditional fixed-income securities. The occurrence of mortgage prepayments is affected by factors including the level of interest rates, general economic conditions, the location and age of the mortgage and other social and demographic conditions. During periods of falling interest rates, the rate of mortgage prepayments tends to increase, thereby tending to decrease the life of mortgage-backed securities. During periods of rising interest rates, the rate of mortgage prepayments usually decreases, thereby tending to increase the life of mortgage-backed securities. If the life of a mortgage-backed security is inaccurately predicted, a Fund may not be able to realize the rate of return it expected.

Adjustable rate mortgage securities (“ARMs”), like traditional mortgage-backed securities, are interests in pools of mortgage loans that provide investors with payments consisting of both principal and interest as mortgage loans in the underlying mortgage pool are paid off by the borrowers. Unlike fixed-rate mortgage-backed securities, ARMs are collateralized by or represent interests in mortgage loans with variable rates of interest. These interest rates are reset at periodic intervals, usually by reference to an interest rate index or market interest rate. Although the rate adjustment feature may act as a buffer to reduce sharp changes in the value of adjustable rate securities, these securities are still subject to changes in value based on, among other things, changes in market interest rates or changes in the issuer’s creditworthiness. Because the interest rates are reset only periodically, changes in the interest rate on ARMs may lag changes in prevailing market interest rates. Also, some ARMs (or the underlying mortgages) are subject to caps or floors that limit the maximum change in the interest rate during a specified period or over the life of the security. As a result, changes in the interest rate on an ARM may not fully reflect changes in prevailing market interest rates during certain periods.

A Fund may also invest in hybrid ARMs, whose underlying mortgages combine fixed-rate and adjustable rate features.

Mortgage-backed and asset-backed securities are less effective than other types of securities as a means of locking in attractive long-term interest rates. One reason is the need to reinvest prepayments of principal; another is the possibility of significant unscheduled prepayments resulting from declines in interest rates. These prepayments would have to be reinvested at lower rates. The automatic interest rate adjustment feature of mortgages underlying ARMs likewise reduces the ability to lock-in attractive rates. As a result, mortgage-backed and asset-backed securities may have less potential for capital appreciation during periods of declining interest rates

4

than other securities of comparable maturities, although they may have a similar risk of decline in market value during periods of rising interest rates. Prepayments may also significantly shorten the effective maturities of these securities, especially during periods of declining interest rates. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing the volatility of the Fund.

At times, some mortgage-backed and asset-backed securities will have higher than market interest rates and therefore will be purchased at a premium above their par value. Prepayments may cause losses on securities purchased at a premium.

CMOs may be issued by a U.S. government agency or instrumentality or by a private issuer. Although payment of the principal of, and interest on, the underlying collateral securing privately issued CMOs may be guaranteed by the U.S. government or its agencies or instrumentalities, these CMOs represent obligations solely of the private issuer and are not insured or guaranteed by the U.S. government, its agencies or instrumentalities or any other person or entity.

Prepayments could cause early retirement of CMOs. CMOs are designed to reduce the risk of prepayment for certain investors by issuing multiple classes of securities, each having different maturities, interest rates and payment schedules, and with the principal and interest on the underlying mortgages allocated among the several classes in various ways. Payment of interest or principal on some classes or series of CMOs may be subject to contingencies or some classes or series may bear some or all of the risk of default on the underlying mortgages. CMOs of different classes or series are generally retired in sequence as the underlying mortgage loans in the mortgage pool are repaid. If enough mortgages are repaid ahead of schedule, the classes or series of a CMO with the earliest maturities generally will be retired prior to their maturities. Thus, the early retirement of particular classes or series of a CMO would have the same effect as the prepayment of mortgages underlying other mortgage-backed securities. Conversely, slower than anticipated prepayments can extend the effective maturities of CMOs, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing their volatility.

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

Subprime mortgage loans, which typically are made to less creditworthy borrowers, have a higher risk of default than conventional mortgage loans. Therefore, mortgage-backed securities backed by subprime mortgage loans may suffer significantly greater declines in value due to defaults or the increased risk of default.

The risks associated with other asset-backed securities (including in particular the risks of issuer default and of early prepayment) are generally similar to those described above for CMOs. In addition, because asset-backed securities generally do not have the benefit of a security interest in the underlying assets that is comparable to a mortgage, asset-backed securities present certain additional risks that are not present with mortgage-backed securities. The ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited. For example, revolving credit receivables are generally unsecured and the debtors on such receivables are entitled to the protection of a number of state and federal consumer credit laws, many of which give debtors the right to set-off certain amounts owed, thereby reducing the balance due. Automobile receivables generally are secured, but by automobiles, rather than by real property.

Asset-backed securities may be collateralized by the fees earned by service providers. The values of asset-backed securities may be substantially dependent on the servicing of the underlying asset 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 circumstances, the mishandling of related documentation may also affect the rights of the security holders in and to the underlying collateral. The insolvency of entities that generate receivables or that utilize the assets may result in added costs and delays in addition to losses associated with a decline in the value of the underlying assets.

Federal, state and local government officials and representatives as well as certain private parties have proposed actions to assist homeowners who own or occupy property subject to mortgages. Certain of those proposals involve actions that would affect the mortgages that underlie or relate to certain mortgage-related securities, including securities or other instruments which a Fund may hold or in which it may invest. Some of those proposals include, among other things, lowering or forgiving principal balances;

5

forbearing, lowering or eliminating interest payments; or utilizing eminent domain powers to seize mortgages, potentially for below market compensation. The prospective or actual implementation of one or more of these proposals may significantly and adversely affect the value and liquidity of securities held by a Fund and could cause the Fund’s net asset value to decline, potentially significantly. Tremendous uncertainty remains in the market concerning the resolution of these issues; the range of proposals and the potential implications of any implemented solution is impossible to predict.

A Fund may invest in any level of the capital structure of an issuer of mortgage-backed or asset-backed securities, including the equity or “first loss” tranche. See “COLLATERALIZED DEBT OBLIGATIONS.”

Consistent with a Fund’s investment objective and policies, the Adviser or Sub-Adviser may also cause a Fund to invest in other types of mortgage- and asset-backed securities offered currently or in the future, including certain yet-to-be-developed types of mortgage- and asset-backed securities which may be created as the market evolves.

BANK LOANS

Bank loans include floating rate loans and institutionally traded floating rate debt obligations issued by asset-backed pools and other issues, and interests therein. Bank loan interests may be acquired from U.S. or foreign commercial banks, insurance companies, finance companies or other financial institutions that have made loans or are members of a lending syndicate or from other holders of loan interests. Bank loans typically pay interest at rates which are re-determined periodically on the basis of a floating base lending rate (such as the London Inter-Bank Offered Rate (“LIBOR”)) plus a premium. Bank loans are typically of below investment grade quality. Bank loans generally (but not always) hold the most senior position in the capital structure of a borrower and are often secured with collateral.

Each Fund may, and the SPDR DoubleLine Total Return Tactical ETF intends to, invest in both secured and unsecured bank loans. Holders’ claims under unsecured loans are subordinated to claims of creditors holding secured indebtedness and possibly other classes of creditors holding unsecured debt. Unsecured loans have a greater risk of default than secured loans, particularly during periods of deteriorating economic conditions. Also, since they do not afford the lender recourse to collateral, unsecured loans are subject to greater risk of nonpayment in the event of default than secured loans. Many such loans are relatively illiquid and may be difficult to value.

Some bank loans are subject to the risk that a court, pursuant to fraudulent conveyance or other similar laws, could subordinate the bank loans to presently existing or future indebtedness of the borrower or take other action detrimental to the holders of the bank loans, including, in certain circumstances, invalidating such bank loans or causing interest previously paid to be refunded to the borrower. If interest were required to be refunded, it could negatively affect a Fund’s performance.

Indebtedness of companies whose creditworthiness is poor involves substantially greater risks and may be highly speculative. Some companies may never pay off their indebtedness or pay only a small fraction of the amount owed. Consequently, when investing in indebtedness of companies with poor credit, a Fund bears a substantial risk of losing the entire amount invested.

Investments in bank loans through a direct assignment of the financial institution’s interest with respect to the bank loan may involve additional risks. For example, if a secured bank loan is foreclosed, a Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that under emerging legal theories of lender liability, a Fund could be held liable as a co-lender.

Bank loans may be structured to include both term loans, which are generally fully funded at the time of investment, and revolving credit facilities, which would require a Fund to make additional investments in the bank loans as required under the terms of the credit facility at the borrower’s demand.

A financial institution’s employment as agent bank may be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent bank would generally be appointed to replace the terminated agent bank, and assets held by the agent bank under the loan agreement would remain available to the holders of such indebtedness. However, if assets held by the agent bank for the benefit of a Fund were determined to be subject to the claims of the agent bank’s general creditors, the Fund may incur certain costs and delays in realizing payments on a bank loan or loan participation and could suffer a loss of principal and/or interest.

BONDS

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

An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Fixed rate bonds generally are also subject to inflation risk, which is the risk that the value of the bond or income from the bond will be worth less in the future as inflation decreases the value of money. This could mean that, as inflation increases, the “real” value of the assets of a fund holding fixed rate bonds can decline, as can the value of the fund’s distributions. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. A Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral).

In addition, each Fund may invest in corporate bonds. The investment return of corporate bonds reflects interest on the bond and changes in the market value of the bond. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by such a security.

COLLATERALIZED DEBT OBLIGATIONS

Collateralized debt obligations (“CDOs”) are a type of asset-backed security and include, among other things, collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. A CBO is a trust which is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans.

The cash flows from the CDO trust are generally split into two or more portions, called tranches, varying in risk and yield. Senior tranches are paid from the cash flows from the underlying assets before the junior tranches and equity or “first loss” tranches. Losses are first borne by the equity tranches, next by the junior tranches, and finally by the senior tranches. Senior tranches pay the lowest interest rates but are generally safer investments than more junior tranches because, should there be any default, senior tranches are typically paid first. The most junior tranches, such as equity tranches, would attract the highest interest rates but suffer the highest risk should the holder of an underlying loan default. If some loans default and the cash collected by the CDO is insufficient to pay all of its investors, those in the lowest, most junior tranches suffer losses first. Since it is partially protected from defaults, a senior tranche from a CDO trust typically has higher ratings and lower yields than the underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, more senior CDO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults and aversion to CDO securities as a class.

The risks of an investment in a CDO depend largely on the quality and type of the collateral and the tranche of the CDO in which a Fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus are not registered under the securities laws. As a result, investments in CDOs may be characterized by a Fund as illiquid securities; however, an active dealer market, or other relevant measures of liquidity, may exist for CDOs allowing a CDO potentially to be deemed liquid by the Adviser or Sub-Adviser under liquidity policies approved by the Board of Trustees of the Trust (the “Board”). In addition to the risks associated with debt instruments ( e.g., interest rate risk and credit risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that a Fund may invest in CDOs that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

COLLATERALIZED LOAN OBLIGATIONS (“CLOs”)

Each Fund may invest in CLOs. A CLO is a financing company (generally called a Special Purpose Vehicle or “SPV”), created to reapportion the risk and return characteristics of a pool of assets. While the assets underlying CLOs are typically Senior Loans, the assets may also include (i) unsecured loans, (ii) other debt securities that are rated below investment grade, (iii) debt tranches of other CLOs and (iv) equity securities incidental to investments in Senior Loans. When investing in CLOs, a Fund will not invest in equity tranches, which are the lowest tranche. However, a Fund may invest in lower debt tranches of CLOs, which typically experience a lower recovery, greater risk of loss or deferral or non-payment of interest than more senior debt tranches of the CLO. In addition, a Fund intends to invest in CLOs consisting primarily of individual Senior Loans of borrowers and not repackaged CLO obligations from other high risk pools. The underlying Senior Loans purchased by CLOs are generally performing at the time of purchase but may become non-performing, distressed or defaulted. CLOs with underlying assets of non-performing, distressed or defaulted loans are not contemplated to comprise a significant portion of a Fund’s investments in CLOs. The key feature of the CLO structure is the prioritization of the cash flows from a pool of debt securities among the several classes of the CLO. The SPV is a company founded solely for the purpose of securitizing payment claims arising out of this diversified asset pool. On this basis, marketable securities are issued by the SPV which, due to the diversification of the underlying risk, generally represent a lower level of risk than the original assets. The redemption of the securities issued by the SPV typically takes place at maturity out of the cash flow generated by the collected claims.

Holders of CLOs bear risks of the underlying investments, index or reference obligation and are subject to counterparty risk.

A Fund may have the right to receive payments only from the CLOs, and generally does not have direct rights against the issuer or the entity that sold the assets to be securitized. While certain CLOs enable the investor to acquire interests in a pool of securities without the brokerage and other expenses associated with directly holding the same securities, investors in CLOs generally pay their share of the CLO’s administrative and other expenses. Although it is difficult to predict whether the prices of indices and securities underlying a CLO will rise or fall, these prices (and, therefore, the prices of CLOs) will be influenced by the same types of political and economic events that affect issuers of securities and capital markets generally. If the issuer of a CLO uses shorter term financing to purchase longer term securities, the issuer may be forced to sell its securities at below market prices if it experiences difficulty in obtaining short-term financing, which may adversely affect the value of the CLOs owned by a Fund.

Certain CLOs may be thinly traded or have a limited trading market. CLOs are typically privately offered and sold. As a result, investments in CLOs may be characterized by a Fund as illiquid securities. In addition to the general risks associated with debt securities discussed herein, CLOs carry additional risks, including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the possibility that the investments in CLOs are subordinate to other classes or tranches thereof; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

COLLATERALIZED MORTGAGE OBLIGATIONS (CMOS) AND MULTICLASS PASS-THROUGH SECURITIES

CMOs are debt obligations collateralized by mortgage loans or mortgage pass-through securities. CMOs may be collateralized by Government National Mortgage Association (“Ginnie Mae”), Federal National Mortgage Association (“Fannie Mae”), or Federal Home Loan Mortgage Corporation (“Freddie Mac”) certificates, but also may be collateralized by whole loans or private mortgage pass-through securities (such collateral is collectively hereinafter referred to as “Mortgage Assets”). Mortgage Assets may be collateralized by commercial or residential uses. Multiclass pass-through securities are equity interests in a trust composed of Mortgage Assets. Payments of principal of and interest on the Mortgage Assets, and any reinvestment income thereon, may require a Fund to pay debt service on the CMOs or make scheduled distributions on the multiclass pass-through securities. CMOs may be issued by federal agencies, or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks and special purpose subsidiaries of the foregoing. The issuer of a series of mortgage pass-through securities may elect to be treated as a Real Estate Mortgage Investment Conduit (“REMIC”). REMICs include governmental and/or private entities that issue a fixed pool of mortgages secured by an interest in real property. REMICs are similar to CMOs in that they issue multiple classes of securities, but unlike CMOs, which are required to be structured as debt securities, REMICs may be structured as indirect ownership interests in the underlying assets of the REMICs themselves. Although CMOs and REMICs differ in certain respects, characteristics of CMOs described below apply in most cases to REMICs, as well.

In a CMO, a series of bonds or certificates is issued in multiple classes. Each class of CMOs, often referred to as a tranche, is issued at a specific fixed or floating coupon rate and has a stated maturity or final distribution date. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semiannual basis. Certain CMOs may have variable or floating interest rates and others may be stripped mortgage securities. For more information on stripped mortgage securities, see “STRIPPED MORTGAGE SECURITIES.”

8

The principal of and interest on the Mortgage Assets may be allocated among the several classes of a CMO series in a number of different ways. Generally, the purpose of the allocation of the cash flow of a CMO to the various classes is to obtain a more predictable cash flow to certain of the individual tranches than exists with the underlying collateral of the CMO. As a general rule, the more predictable the cash flow is on a CMO tranche, the lower the anticipated yield will be on that tranche at the time of issuance relative to prevailing market yields on other mortgage-backed securities. As part of the process of creating more predictable cash flows on most of the tranches in a series of CMOs, one or more tranches generally must be created that absorb most of the volatility in the cash flows on the underlying mortgage loans. The yields on these tranches are generally higher than prevailing market yields on mortgage-backed securities with similar maturities. As a result of the uncertainty of the cash flows of these tranches, the market prices of and yield on these tranches generally are more volatile. See “COLLATERALIZED DEBT OBLIGATIONS” for a discussion on investments in structured products with multiple tranches.

CMO RESIDUALS

CMO residuals are mortgage securities issued by agencies or instrumentalities of the U.S. government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks and special purpose entities of the foregoing. The cash flow generated by the mortgage assets underlying a series of a CMO is applied first to make required payments of principal and interest on the securities or certificates issued by the CMO and second to pay the related administrative expenses and any management fee of the issuer. The residual in a CMO structure generally represents the interest in any excess cash flow remaining after making the foregoing payments. Each payment of such excess cash flow to a holder of the related CMO residual represents income and/or a return of capital. The amount of residual cash flow resulting from a CMO will depend on, among other things, the characteristics of the mortgage assets, the coupon rate of each class of CMO, prevailing interest rates, the amount of administrative expenses and the pre-payment experience on the mortgage assets. In particular, the yield to maturity on CMO residuals is extremely sensitive to pre-payments on the related underlying mortgage assets. In addition, if a series of a CMO includes a class that bears interest at an adjustable rate, the yield to maturity on the related CMO residual will also be extremely sensitive to changes in the level of the index upon which interest rate adjustments are based. As described below with respect to stripped mortgage-backed securities, in certain circumstances a Fund may fail to recoup fully its initial investment in a CMO residual. CMO residuals are generally purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. In addition, CMO residuals may, or pursuant to an exemption therefrom, may not have been registered under the Securities Act. CMO residuals, whether or not registered under the Securities Act, may be subject to certain restrictions on transferability, and may be deemed “illiquid.”

COMMERCIAL PAPER

Commercial paper consists of short-term, promissory notes issued by banks, corporations and other entities to finance short-term credit needs. These securities generally are discounted but sometimes may be interest bearing.

COMMON STOCK

Risks inherent in investing in equity securities include the risk that the financial condition of issuers may become impaired or that the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of a Fund’s portfolio securities and therefore a decrease in the value of its Fund Shares). Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence and perceptions change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic or banking crises.

CONCENTRATION

The Funds do not intend to concentrate their investments in any particular industry. The Funds (except the SPDR MFS Systematic Core Equity ETF, SPDR MFS Systematic Growth Equity ETF and SPDR MFS Systematic Value Equity ETF (collectively, the “MFS ETFs”)) look to the Global Industry Classification Standard Level 3 (Industries) in making industry determinations. The MFS ETFs look to Massachusetts Financial Services Company’s (“MFS”) customized set of industry groups for making industry determinations based on classifications developed by third party providers. The Trust’s general policy is to exclude securities of the U.S. government and its agencies or instrumentalities when measuring industry concentration.

CONVERTIBLE SECURITIES

Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by a Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at a price above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates. When the underlying common stocks decline in value, convertible securities will tend not to decline to the same extent because of the interest or dividend payments and the repayment of principal at maturity for certain types of convertible securities. However, securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder. When the underlying common stocks rise in value, the value of convertible securities may also be expected to increase. At the same time, however, the difference between the market value of convertible securities and their conversion value will narrow, which means that the value of convertible securities will generally not increase to the same extent as the value of the underlying common stocks. Because convertible securities may also be interest-rate sensitive, their value may increase as interest rates fall and decrease as interest rates rise. Convertible securities are also subject to credit risk, and are often lower-quality securities.

EXCHANGE-TRADED PRODUCTS

ETPs include exchange traded funds (“ETFs”) registered under the 1940 Act; exchange traded commodity trusts; and exchange traded notes (“ETNs”). The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Funds may invest, as well as a management fee for managing the Funds. It is possible that a conflict of interest among the Funds and Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Funds 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 a Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETP. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which a Fund 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 Funds.

Each Fund may invest in new ETPs or ETPs that have not yet established a deep trading market at the time of investment. Shares of such ETPs may experience limited trading volume and less liquidity, in which case the “spread” (the difference between bid price and ask price) may be higher.

EXCHANGE-TRADED FUNDS

Each Fund may invest in other ETFs (including ETFs managed by the Adviser). ETFs may be structured as investment companies that are registered under the 1940 Act, typically as open-end funds or unit investment trusts. These ETFs are generally based on specific domestic and foreign market securities indices. An “index-based ETF” seeks to provide investment results that match the performance of an index by holding in its portfolio either the contents of the index or a representative sample of the securities in the index. An “actively-managed ETF” invests in securities based on an adviser’s investment strategy. An “enhanced ETF” seeks to provide investment results that match a positive or negative multiple of the performance of an underlying index. In seeking to provide such results, an ETF and, in particular, an enhanced ETF, may engage in short sales of securities included in the underlying index and may invest in derivatives instruments, such as equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Alternatively, ETFs may be structured as grantor trusts or other forms of pooled investment vehicles that are not registered or regulated under the 1940 Act. These ETFs typically hold commodities, precious metals, currency or other non-securities investments. ETFs, like mutual funds, have expenses associated with their operation, such as advisory and custody fees. When a fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, including the brokerage costs associated with the purchase and sale of shares of the ETF, the fund will bear a pro rata portion of the ETF’s expenses. In addition, it may be more costly to own an ETF than to directly own the securities or other investments held by the ETF because of ETF expenses. The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities or other investments held by the ETF, although lack of liquidity in the market for the shares of an ETF could result in the ETF’s value being more volatile than the underlying securities or other investments.

EXCHANGE-TRADED NOTES

ETNs are debt obligations of investment banks which are traded on exchanges and the returns of which are linked to the performance of market indexes. In addition to trading ETNs on exchanges, investors may redeem ETNs directly with the issuer on a weekly basis, typically in a minimum amount of 50,000 units, or hold the ETNs until maturity. ETNs may be riskier than ordinary debt securities and may have no principal protection. A fund’s investment in an ETN may be influenced by many unpredictable factors, including highly volatile commodities prices, changes in supply and demand relationships, weather, agriculture, trade, changes in interest rates, and monetary and other governmental policies, action and inaction. Investing in ETNs is not equivalent to investing directly in index components or the relevant index itself. Because ETNs are debt securities, they possess credit risk; if the issuer has financial difficulties or goes bankrupt, the investor may not receive the return it was promised.

FOREIGN CURRENCY TRANSACTIONS

Each 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). Although foreign exchange dealers generally do not charge a fee for such conversions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency at one rate, while offering a lesser rate of exchange should the counterparty desire to resell that currency to the dealer. Forward contracts are customized transactions that generally require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future although a Fund may also enter into non-deliverable currency forward contracts (“NDFs”) that contractually require the netting of the parties’ liabilities. Forwards, including NDFs, can have substantial price volatility. While foreign currency transactions on a spot and forward basis are exempt from the definition of “swap” under the Commodity Exchange Act (“CEA”), NDFs are not, and, thus, are subject to the jurisdiction of the Commodity Futures Trading Commission (“CFTC”). Forward contracts are generally traded in an interbank market directly between currency traders (usually large commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange. In the event that the parties to a forward contract agree to offset or terminate the contract before its maturity, the contract is no longer exempt from the definition of “swap” under the CEA and shall be treated as a swap. At the discretion of the Adviser, a Fund may enter into forward currency exchange contracts for hedging purposes to help reduce the risks and volatility caused by changes in foreign currency exchange rates, or to gain exposure to certain currencies. When used for hedging purposes, they tend to limit any potential gain that may be realized if the value of a Fund’s foreign holdings increases because of currency fluctuations.

FUTURES CONTRACTS, OPTIONS AND SWAP AGREEMENTS

Each Fund may invest up to 20% of its assets in derivatives, including exchange-traded futures on Treasuries or Eurodollars, U.S. exchange-traded or OTC put and call options contracts and exchange-traded or OTC swap transactions (including interest rate swaps, total return swaps, excess return swaps, and credit default swaps). The Fund will segregate cash and/or appropriate liquid assets if required to do so by SEC or CFTC regulation or interpretation.

Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet fully known and may not be for some time. New regulations could adversely affect the value, availability and performance of certain derivative instruments, may make them more costly, and may limit or restrict their use by the Funds.

Futures contracts generally provide for the future sale by one party and purchase by another party of a specified commodity or security at a specified future time and at a specified price. Index futures contracts are settled daily with a payment by one party to the other of a cash amount based on the difference between the level of the index specified in the contract from one day to the next. A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract originally was written. Although the value of an index might be a function of the value of certain specified securities, physical delivery of these securities is not always made. A public market exists in futures contracts covering a number of indexes, as well as financial instruments, including, without limitation: U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates; three-month U.S. Treasury bills; 90-day commercial paper; bank certificates of deposit; Eurodollar certificates of deposit; the Australian Dollar; the Canadian Dollar; the British Pound; the Japanese Yen; the Swiss Franc; the Mexican Peso; and certain multinational currencies, such as the Euro. It is expected that other futures contracts will be developed and traded in the future. Futures contracts are standardized as to maturity date and underlying instrument and are traded on futures exchanges.

The Funds may purchase and write (sell) call and put options on futures. Options on futures give the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price upon expiration of, or at any time during the period of, the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true.

11

A fund is required to make a good faith margin deposit in cash or U.S. government securities (or other eligible collateral) with a broker or custodian to initiate and maintain open positions in futures contracts. A margin deposit is intended to assure completion of the contract (delivery or acceptance of the underlying commodity or payment of the cash settlement amount) if it is not terminated prior to the specified delivery date. Brokers may establish deposit requirements which are higher than the exchange minimums. Futures contracts are customarily purchased and sold on margin deposits which may range upward from less than 5% of the value of the contract being traded.

After a futures contract position is opened, the value of the contract is marked to market daily. If the futures contract price changes to the extent that the margin on deposit does not satisfy price changes, additional payments will be required. Conversely, change in the contract value may reduce the required margin, resulting in a repayment of excess margin to the contract holder. Variation margin payments are made to and from the futures broker for as long as the contract remains open. In such case, a Fund would expect to earn interest income on its margin deposits. Although some futures contracts call for making or taking delivery of the underlying commodity, generally these obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (involving the same exchange, underlying security or index and delivery month). If an offsetting purchase price is less than the original sale price, the Fund realizes a capital gain, or if it is more, the Fund realizes a capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Fund realizes a capital gain, or if it is less, the Fund realizes a capital loss. The transaction costs also must be included in these calculations.

Regulation Under the Commodity Exchange Act. To the extent a Fund uses commodity interests, such as futures swaps and options on futures, it will do so in accordance with Rule 4.5 of the CEA. The Trust, on behalf of each Fund, has filed a notice of eligibility for exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that the Fund is not subject to registration or regulation as a commodity pool operator under the CEA.

Restrictions on Trading in Commodity Interests. With respect to each Fund, the Trust has claimed an exemption from registration as a commodity pool operator under the CEA pursuant to CFTC Rule 4.5 and, therefore, is not subject to the registration and regulatory requirements of the CEA. Each Fund reserves the right to engage in transactions involving futures, options thereon and swaps to the extent allowed by the CFTC regulations in effect from time to time and in accordance with the Fund’s policies. Each Fund would take steps to prevent its futures positions from “leveraging” its securities holdings. When it has a long futures position, it will maintain with its custodian bank assets substantially identical to those underlying the contract or cash and equivalents (or a combination of the foregoing) having a value equal to the net obligation of the Fund under the contract (less the value of any margin deposits in connection with the position). When it has a short futures position, it will maintain with its custodian bank assets substantially identical to those underlying the contract or cash and equivalents (or a combination of the foregoing) having a value equal to the net obligation of the Fund under the contract (less the value of any margin deposits in connection with the position).

Options. A Fund may purchase and sell put and call options. Such options may relate to particular securities and may or may not be listed on a national securities exchange and issued by the Options Clearing Corporation. Options trading is a highly specialized activity that entails greater than ordinary investment risk. Options on particular securities may be more volatile than the underlying securities, and therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying securities themselves.

Short Sales “Against the Box.” A Fund may engage in short sales “against the box.” In a short sale against the box, the Fund agrees to sell at a future date a security that it either contemporaneously owns or has the right to acquire at no extra cost. If the price of the security has declined at the time the Fund is required to deliver the security, the Fund will benefit from the difference in the price. If the price of the security has increased, the Fund will be required to pay the difference.

Swap Transactions. A Fund may enter into swap transactions, including interest rate, swap, credit default swap, NDF, and total return swap transactions. Swap transactions are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make payments to the first party based on the return of a different specified rate, index or asset. Swap transaction will usually be done on a net basis, i.e. , where the two parties make net payments with a Fund receiving or paying, as the case may be, only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of cash or equivalents having an aggregate value at least equal to the accrued excess is maintained by the Fund. Swaps may be used in conjunction with other instruments to offset interest rate, currency or other underlying risks. For example, interest rate swaps may be offset with “caps,” “floors” or “collars”. A “cap” is essentially a call option which places a limit on the amount of floating rate interest that must be paid on a certain principal amount. A “floor” is essentially a put option which places a limit on the minimum amount that would be paid on a certain principal amount. A “collar” is essentially a combination of a long cap and a short floor where the limits are set at different levels.

The use of swap transactions by a Fund entails certain risks, which may be different from, or possibly greater than, the risks associated with investing directly in the securities and other investments that are the referenced asset for the swap agreement. Swaps are highly

12

specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with stocks, bonds, and other traditional investments. The use of a swap requires an understanding not only of the referenced asset, reference rate, or index, but also of the swap itself, without the benefit of observing the performance of the swap under all the possible market conditions. Because some swap transactions have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain swaps have the potential for unlimited loss, regardless of the size of the initial investment.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) that was signed into law on July 21, 2010 created a new statutory framework that comprehensively regulated the over-the-counter (“OTC”) derivatives markets for the first time. Key Dodd-Frank Act provisions relating to OTC derivatives require rulemaking by the SEC and the CFTC, not all of which has been proposed or finalized as at the date of this SAI. Prior to the Dodd-Frank Act, the OTC derivatives markets were traditionally traded on a bilateral basis (so-called “bilateral OTC transactions”). Under the Dodd-Frank Act, certain OTC derivatives transactions are now required to be centrally cleared and traded on exchanges or electronic trading platforms called swap execution facilities (“SEFs”).

Bilateral OTC transactions differ from exchange-traded or cleared derivatives transactions in several respects. Bilateral OTC transactions are transacted directly with dealers and not with a clearing corporation. Without the availability of a clearing corporation, bilateral OTC transaction pricing is normally done by reference to information from market makers and/or available index data, which information is carefully monitored by the Adviser and verified in appropriate cases. As bilateral OTC transactions are entered into directly with a dealer, there is a risk of nonperformance by the dealer as a result of its insolvency or otherwise. Under recently-adopted regulations by the CFTC and federal banking regulators (“Margin Rules”), a Fund is required to post collateral (known as variation margin) to cover the mark-to-market exposure in respect of its uncleared swaps. The Margin Rules also mandate that collateral in the form of initial margin be posted to cover potential future exposure attributable to uncleared swap transactions. However, due to the compliance timeline within the Margin Rules, it is unlikely that the Funds will be required to comply with such initial margin requirements until March 1, 2020. In the event a Fund is required to post collateral in the form of initial margin or variation margin in respect of its uncleared swap transactions, all such collateral will be posted with a third party custodian pursuant to a triparty custody agreement between the Fund, its dealer counterparty and an unaffiliated custodian.

The requirement to execute certain OTC derivatives contracts on SEFs may offer certain advantages over traditional bilateral OTC trading, such as ease of execution, price transparency, increased liquidity and/or favorable pricing. However, SEF trading may make it more difficult and costly for a Fund to enter into highly tailored or customized transactions and may result in additional costs and risks. Market participants such as the Funds that execute derivatives contracts through a SEF, whether directly or through a broker intermediary, are required to submit to the jurisdiction of the SEF and comply with SEF and CFTC rules and regulations which impose, among other things disclosure and recordkeeping obligations. In addition, a Fund will generally incur SEF or broker intermediary fees when it trades on a SEF. A Fund may also be required to indemnify the SEF or broker intermediary for any losses or costs that may result from the Fund’s transactions on the SEF.

Total Return Swaps. A Fund may enter into total return swap transactions for investment purposes. Total return swaps are transactions in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or security indexes during the specified period, in return for periodic payments based on a fixed or variable interest rate of the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market, including in cases in which there may be disadvantages associated with direct ownership of a particular security. In a typical total return equity swap, payments made by a Fund or the counterparty are based on the total return of a particular reference asset or assets (such as an equity security, a combination of such securities, or an index). That is, one party agrees to pay another party the return on a stock, basket of stocks, or stock index in return for a specified interest rate. By entering into an equity index swap, for example, the index receiver can gain exposure to stocks making up the index of securities without actually purchasing those stocks. Total return swaps involve not only the risk associated with the investment in the underlying securities, but also the risk of the counterparty not fulfilling its obligations under the agreement.

Credit Default Swaps. A Fund may enter into credit default swap transactions for investment purposes. A credit default swap transaction may have as reference obligations one or more securities that are not currently held by the Fund. A Fund may be either the protection buyer or protection seller in the transaction. Credit default swaps may also be structured based on the debt of a basket of issuers, rather than a single issuer, and may be customized with respect to the default event that triggers purchase or other factors. As a protection seller, a Fund would generally receive an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the protection seller must pay the protection buyer the full face amount of the reference obligations that may have little or no value. The notional value of the credit default swap will be used to segregate liquid assets for selling protection on credit default swaps. If a Fund were a protection buyer and no credit event occurred during the term of the swap, the Fund would recover nothing if the swap were held through its termination date. However, if a credit event occurred, the protection buyer may elect to receive the full notional value of the swap in exchange for an equal face amount of the reference obligation that may have little or no value. Where a Fund is the protection buyer, credit default swaps involve the risk that the seller may fail to satisfy its payment obligations to the Fund in the event of a default. The purchase of credit default swaps involves costs, which will reduce a Fund’s return. When a Fund buys credit default swaps it will segregate an amount at least equal to the amount of any accrued premium payment obligations including amounts for early terminations.

13

Currency Swaps. A Fund may enter into currency swap transactions for investment purposes. Currency swaps are similar to interest rate swaps, except that they involve multiple currencies. A Fund may enter into a currency swap when it has exposure to one currency and desires exposure to a different currency. Typically, the interest rates that determine the currency swap payments are fixed, although occasionally one or both parties may pay a floating rate of interest. Unlike an interest rate swap, however, the principal amounts are exchanged at the beginning of the contract and returned at the end of the contract. In addition to paying and receiving amounts at the beginning and end of the transaction, both sides will have to pay in full on a periodic basis based upon the currency they have borrowed. Change in foreign exchange rates and changes in interest rates, as described above, may negatively affect currency swaps.

Interest Rate Swaps. A Fund may enter into an interest rate swap in an effort to protect against declines in the value of fixed income securities held by the Fund. In such an instance, the Fund may agree to pay a fixed rate (multiplied by a notional amount) while a counterparty agrees to pay a floating rate (multiplied by the same notional amount). If interest rates rise, resulting in a diminution in the value of the Fund’s securities, the Fund would receive payments under the swap that would offset, in whole or in part, such diminution in value.

Options on Swaps. An option on a swap agreement, or a “swaption,” is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. In return, the purchaser pays a “premium” to the seller of the contract. The seller of the contract receives the premium and bears the risk of unfavorable changes on the underlying swap. A Fund may write (sell) and purchase put and call swaptions. A Fund may also enter into swaptions on either an asset-based or liability-based basis, depending on whether the Fund is hedging its assets or its liabilities. A Fund may write (sell) and purchase put and call swaptions to the same extent it may make use of standard options on securities or other instruments. A Fund may enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its holdings, as a duration management technique, to protect against an increase in the price of securities the Fund anticipates purchasing at a later date, or for any other purposes, such as for speculation to increase returns. Swaptions are generally subject to the same risks involved in a Fund’s use of options.

Depending on the terms of the particular option agreement, a Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When a Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when a Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Certain additional risk factors related to derivatives are discussed below:

Derivatives Risk. Under recently adopted rules by the CFTC, transactions in some types of interest rate swaps and index credit default swaps on North American and European indices are required to be cleared. In addition, the CFTC may promulgate additional regulations that require clearing of other classes of swaps. In a cleared derivatives transaction (which includes commodities futures and cleared swaps transactions), a Fund’s counterparty is a clearing house (such as CME, ICE Clear Credit or LCH. Clearnet), rather than a bank or broker. Since each Fund is not a member of a clearing house and only members of a clearing house can participate directly in the clearing house, a Fund holds cleared derivatives through accounts at clearing members, who are futures commission merchants that are members of the clearing houses and who have the appropriate regulatory approvals to engage in cleared swap transactions. A Fund makes and receives payments owed under cleared derivatives transactions (including margin payments) through its accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house. In contrast to bilateral OTC transactions, clearing members generally can require termination of existing cleared derivatives transactions at any time and increases in margin above the margin that it required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions and to terminate transactions. Any such increase or termination could interfere with the ability of a Fund to pursue its investment strategy. Also, a Fund is subject to execution risk if it enters into a derivatives transaction that is required to be cleared (or that the Advisor expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. While the documentation in place between a Fund and their clearing members generally provides that the clearing members will accept for clearing all transactions submitted for clearing that are within credit limits specified by the clearing members in advance, the Fund could be subject to this execution risk if the Fund submits for clearing transactions that exceed such credit limits, if the clearing house does not accept the transactions for clearing, or if the clearing members do not comply with their agreement to clear such transactions. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of any increase in the value of the transaction after the time of the transaction. In addition, new regulations could, among other things, restrict a Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund or increasing margin or capital requirements. If a Fund is not able to enter into a particular derivatives transaction, the Fund’s investment performance and risk profile could be adversely affected as a result.

14

Counterparty Risk. Counterparty risk with respect to OTC derivatives may be affected by new regulations promulgated by the CFTC and SEC affecting the derivatives market. As described under “Derivatives Risk” above, some derivatives transactions are required to be cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared derivatives position, rather than the credit risk of its original counterparty to the derivative transaction. Clearing members are required to segregate all funds received from customers with respect to cleared derivatives transactions from the clearing member’s proprietary assets. However, all funds and other property received by a clearing broker from its customers are generally held by the clearing broker on a commingled basis in an omnibus account, which may also invest those funds in certain instruments permitted under the applicable regulations. Also, the clearing member transfers to the clearing house the amount of margin required by the clearing house for cleared derivatives transactions, which amounts are generally held in the relevant omnibus account at the clearing house for all customers of the clearing member.

For commodities futures positions, the clearing house may use all of the collateral held in the clearing member’s omnibus account to meet a loss in that account, without regard to which customer in fact supplied that collateral. Accordingly, in addition to bearing the credit risk of its clearing member, each customer to a futures transaction also bears “fellow customer” risk from other customers of the clearing member. However, with respect to cleared swaps positions, recent regulations promulgated by the CFTC require that the clearing member notify the clearing house of the amount of initial margin provided by the clearing member to the clearing house that is attributable to each customer. Because margin in respect of cleared swaps must be earmarked for specific clearing member customers, the clearing house may not use the collateral of one customer to cover the obligations of another customer. However, if the clearing member does not provide accurate reporting, a Fund is subject to the risk that a clearing house will use the Fund’s assets held in an omnibus account at the clearing house to satisfy payment obligations of a defaulting customer of the clearing member to the clearing house. In addition, clearing members may generally choose to provide to the clearing house the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount for each customer.

FUTURE DEVELOPMENTS

A Fund may take advantage of opportunities in the area of options and futures contracts, options on futures contracts, warrants, swaps and any other investments which are not presently contemplated for use by the Fund or which are not currently available but which may be developed, to the extent such opportunities are both consistent with the Fund’s investment objective and legally permissible for the Fund. Before entering into such transactions or making any such investment, the Fund will provide appropriate disclosure.

GOVERNMENT MORTGAGE PASS-THROUGH SECURITIES

Each Fund may invest in mortgage pass-through securities representing participation interests in pools of residential mortgage loans purchased from individual lenders by an agency, instrumentality or sponsored corporation of the United States government (“Federal Agency”) or originated by private lenders and guaranteed, to the extent provided in such securities, by a Federal Agency. Such securities, which are ownership interests in the underlying mortgage loans, differ from conventional debt securities, which provide for periodic payment of interest in fixed amounts (usually semiannually) and principal payments at payments (not necessarily in fixed amounts) that are a pass-through of the monthly interest and principal payments (including any prepayments) made by the individual borrowers on the pooled mortgage loans, net of any fees paid to the guarantor of such securities and the servicer of the underlying mortgage loans.

The government mortgage pass-through securities in which the Fund may invest include those issued or guaranteed by Ginnie Mae, Fannie Mae and Freddie Mac. Ginnie Mae certificates are direct obligations of the U.S. government and, as such, are backed by the full faith and credit of the United States. Fannie Mae is a federally chartered, privately owned corporation and Freddie Mac is a corporate instrumentality of the United States. Fannie Mae and Freddie Mac certificates are not backed by the full faith and credit of the United States but the issuing agency or instrumentality has the right to borrow, to meet its obligations, from an existing line of credit with the U.S. Treasury. The U.S. Treasury has no legal obligation to provide such line of credit and may choose not to do so.

Certificates for these types of mortgage-backed securities evidence an interest in a specific pool of mortgages. These certificates are, in most cases, modified pass-through instruments, wherein the issuing agency guarantees the payment of principal and interest on mortgages underlying the certificates, whether or not such amounts are collected by the issuer on the underlying mortgages.

The Housing and Economic Recovery Act of 2008 (“HERA”) authorized the Secretary of the Treasury to support Fannie Mae, Freddie Mac, and the Federal Home Loan Banks (“FHLBs”) (collectively, the “GSEs”) by purchasing obligations and other securities from those government-sponsored enterprises. HERA gave the Secretary of the Treasury broad authority to determine the conditions and amounts of such purchases.

15

On September 6, 2008, the Federal Housing Finance Agency (“FHFA”) placed Fannie Mae and Freddie Mac into conservatorship. As the conservator, FHFA succeeded to all rights, titles, powers and privileges of Fannie Mae and Freddie Mac and of any stockholder, officer or director of Fannie Mae and Freddie Mac with respect to Fannie Mae and Freddie Mac and the assets of Fannie Mae and Freddie Mac. FHFA selected a new chief executive officer and chairman of the board of directors for Fannie Mae and Freddie Mac.

In connection with the conservatorship, the U.S. Treasury, exercising powers granted to it under HERA, entered into a Senior Preferred Stock Purchase Agreement (“SPA”) with each of Fannie Mae and Freddie Mac pursuant to which the U.S. Treasury will purchase up to an aggregate of $100 billion of each of Fannie Mae and Freddie Mac to maintain a positive net worth in each enterprise. This agreement contains various covenants that severely limit each enterprise’s operations. In exchange for entering into these agreements, the U.S. Treasury received $1 billion of each enterprise’s senior preferred stock and warrants to purchase 79.9% of each enterprise’s common stock. On February 18, 2009, the U.S. Treasury announced that it was doubling the size of its commitment to each enterprise under the Senior Preferred Stock Program to $200 billion. The U.S. Treasury’s obligations under the Senior Preferred Stock Program are for an indefinite period of time for a maximum amount of $200 billion per enterprise. On December 24, 2009, the U.S. Treasury announced further amendments to the SPAs which included additional financial support for each GSE through the end of 2012 and changes to the limits on their retained mortgage portfolios. On August 17, 2012, the U.S. Treasury announced that it was again amending the Agreement to terminate the requirement that Fannie Mae and Freddie Mac each pay a 10% dividend annually on all amounts of received under the funding commitment. Instead, they will transfer to the U.S. Treasury on a quarterly basis all profits earned during a quarter that exceed a capital reserve amount of $3 billion. The U.S. Treasury stated that the purpose of the change was to wind down Freddie Mac and Fannie Mae and to benefit taxpayers. At the start of 2013, the unlimited support the U.S. Treasury extended to the two companies expired — Fannie Mae’s bailout is now capped at $125 billion and Freddie Mac has a limit of $149 billion. In August 2013, President Obama announced his proposal to shut down Freddie Mac and Fannie Mae as part of a plan to overhaul the U.S.’s mortgage finance system. Until further action is taken, the actions of the U.S. Treasury are intended to ensure that Fannie Mae and Freddie Mac maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. No assurance can be given that the U.S. Treasury initiatives will be successful.

Under the Federal Housing Finance Regulatory Reform Act of 2008 (the “Reform Act”), which was included as part of Housing and Economic Recovery Act of 2008, FHFA, as conservator or receiver, has the power to repudiate any contract entered into by Fannie Mae or Freddie Mac prior to FHFA’s appointment as conservator or receiver, as applicable, if FHFA determines, in its sole discretion, that performance of the contract is burdensome and that repudiation of the contract promotes the orderly administration of Fannie Mae’s or Freddie Mac’s affairs. The Reform Act requires FHFA to exercise its right to repudiate any contract within a reasonable period of time after its appointment as conservator or receiver.

FHFA, in its capacity as conservator, has indicated that it has no intention to repudiate the guaranty obligations of Fannie Mae or Freddie Mac because FHFA views repudiation as incompatible with the goals of the conservatorship. However, in the event that FHFA, as conservator or if it is later appointed as receiver for Fannie Mae or Freddie Mac, were to repudiate any such guaranty obligation, the conservatorship or receivership estate, as applicable, would be liable for actual direct compensatory damages in accordance with the provisions of the Reform Act. Any such liability could be satisfied only to the extent of Fannie Mae’s or Freddie Mac’s available assets. The future financial performance of Fannie Mae and Freddie Mac is heavily dependent on the performance of the U.S. housing market.

In the event of repudiation, the payments of interest to holders of Fannie Mae, or Freddie Mac mortgage-backed securities would be reduced if payments on the mortgage loans represented in the mortgage loan groups related to such mortgage-backed securities are not made by the borrowers or advanced by the servicer. Any actual direct compensatory damages for repudiating these guaranty obligations may not be sufficient to offset any shortfalls experienced by such mortgage-backed security holders.

Further, in its capacity as conservator or receiver, FHFA has the right to transfer or sell any asset or liability of Fannie Mae or Freddie Mac without any approval, assignment or consent. Although FHFA has stated that it has no present intention to do so, if FHFA, as conservator or receiver, were to transfer any such guaranty obligation to another party, holders of Fannie Mae or Freddie Mac mortgage-backed securities would have to rely on that party for satisfaction of the guaranty obligation and would be exposed to the credit risk of that party.

In addition, certain rights provided to holders of mortgage-backed securities issued by Fannie Mae and Freddie Mac under the operative documents related to such securities may not be enforced against FHFA, or enforcement of such rights may be delayed, during the conservatorship or any future receivership. The operative documents for Fannie Mae and Freddie Mac mortgage-backed securities may provide (or with respect to securities issued prior to the date of the appointment of the conservator may have provided) that upon the occurrence of an event of default on the part of Fannie Mae or Freddie Mac, in its capacity as guarantor, which includes the appointment of a conservator or receiver, holders of such mortgage-backed securities have the right to replace Fannie Mae or Freddie Mac as trustee if the requisite percentage of mortgage-backed security holders consent. The Reform Act prevents mortgage-backed security holders from enforcing such rights if the event of default arises solely because a conservator or receiver has been appointed. The Reform Act also provides that no person may exercise any right or power to terminate, accelerate or declare an event

16

of default under certain contracts to which Fannie Mae or Freddie Mac is a party, or obtain possession of or exercise control over any property of Fannie Mae or Freddie Mac, or affect any contractual rights of Fannie Mae or Freddie Mac, without the approval of FHFA, as conservator or receiver, for a period of 45 or 90 days following the appointment of FHFA as conservator or receiver, respectively.

HIGH YIELD SECURITIES

Investment in high yield securities generally provides greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and credit risk. These high yield securities are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of debt securities that are high yield may be more complex than for issuers of higher quality debt securities. In addition, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, but can also be issued by governments. Such issuers are generally less able than more financially stable issuers to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial.

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

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

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which a Fund could sell a high yield security, and could adversely affect the daily net asset value per share of a Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available.

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

INFLATION-PROTECTED OBLIGATIONS

Each Fund may invest in inflation-protected public obligations, commonly known as “TIPS,” of the U.S. Treasury, as well as TIPS of major governments and emerging market countries, excluding the United States. TIPS are a type of security issued by a government that is designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation—a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the Consumer Price Index. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises or falls, both the principal value and the interest payments will increase or decrease. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

INVERSE FLOATERS

An inverse floater is a type of instrument that bears a floating or variable interest rate that moves in the opposite direction to interest rates generally or the interest rate on another security or index. Changes in interest rates generally, or the interest rate of the other security or index, inversely affect the interest rate paid on the inverse floater, with the result that the inverse floater’s price will be considerably more volatile than that of a fixed-rate bond. Brokers typically create inverse floaters by depositing an income-producing instrument, which may be a mortgage-backed security, in a trust. The trust in turn issues a variable rate security and inverse floaters. The returns on the inverse floaters may be leveraged, increasing substantially their volatility and interest rate sensitivity. The rate at which interest is paid by the trust on an inverse floater may vary by a magnitude that exceeds the magnitude of the change in a reference rate of interest (typically a short term interest rate), and the market prices of inverse floaters may as a result be highly

17

sensitive to changes in interest rates and in prepayment rates on the underlying securities, and may decrease significantly when interest rates increase or prepayment rates change. The interest rate for the variable rate security is typically determined by an index or an auction process, while the inverse floater holder receives the balance of the income from the underlying income-producing instrument less an auction fee.

INVESTMENT COMPANIES

Each Fund may invest in the securities of other investment companies, including affiliated funds, money market funds and closed-end funds, subject to applicable limitations under Section 12(d)(1) of the 1940 Act. Pursuant to Section 12(d)(1), a fund may invest in the securities of another investment company (the “acquired company”) provided that the fund, immediately after such purchase or acquisition, does not own in the aggregate: (i) more than 3% of the total outstanding voting stock of the acquired company; (ii) securities issued by the acquired company having an aggregate value in excess of 5% of the value of the total assets of the fund; (iii) securities issued by the acquired company and all other investment companies (other than Treasury stock of the fund) having an aggregate value in excess of 10% of the value of the total assets of the fund; or (iv) in the case of investment in a closed-end fund, more than 10% of the total outstanding voting stock of the acquired company. A fund may also invest in the securities of other investment companies if such securities are the only investment securities held by the fund, such as through a master-feeder arrangement. To the extent allowed by law, regulation, a Fund’s investment restrictions and the Trust’s exemptive relief, a Fund may invest its assets in securities of investment companies that are affiliated funds and/or money market funds in excess of the limits discussed above.

To the extent a fund invests in and, thus, is a shareholder of, another investment company, the fund’s shareholders will indirectly bear the fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the fund to the fund’s own investment adviser and the other expenses that the fund bears directly in connection with the fund’s own operations.

LENDING PORTFOLIO SECURITIES

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

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

A Fund may pay a portion of the interest or fees earned from securities lending to a borrower as described above, and to one or more securities lending agents approved by the Board who administer the lending program for the Fund in accordance with guidelines approved by the Board. In such capacity, the lending agent causes the delivery of loaned securities from the Fund to borrowers, arranges for the return of loaned securities to the Fund at the termination of a loan, requests deposit of collateral, monitors the daily value of the loaned securities and collateral, requests that borrowers add to the collateral when required by the loan agreements, and provides recordkeeping and accounting services necessary for the operation of the program. State Street Bank and Trust Company (“State Street”), an affiliate of the Trust, has been approved by the Board to serve as securities lending agent for each Fund and the Trust has entered into an agreement with State Street for such services. Among other matters, the Trust has agreed to indemnify State Street for certain liabilities. State Street has received an order of exemption from the SEC under Sections 17(a) and 12(d)(1) under the 1940 Act to serve as the lending agent for affiliated investment companies such as the Trust and to invest the cash collateral received from loan transactions to be invested in an affiliated cash collateral fund. Securities lending involves exposure to certain risks, including operational risk ( i.e. , the risk of losses resulting from problems in the settlement and accounting process – especially so in certain international markets such as Taiwan), “gap” risk ( i.e. , the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), risk of loss of collateral, credit, legal, counterparty and market risk. Although State Street has agreed to provide each Fund with indemnification in the event of a borrower default, each Fund is still exposed to the risk of losses in the event a borrower does not return the Fund’s securities as agreed. For example, delays in recovery of lent securities may cause a Fund to lose the opportunity to sell the securities at a desirable price.

18

LEVERAGING

While the Funds do not anticipate doing so, each Fund may borrow money in an amount greater than 5% of the value of their respective total assets. However, a Fund may not borrow money from a bank in an amount greater than 33 ¹ / ₃ % of the value of the Fund’s total assets. Borrowing for investment purposes is one form of leverage. Leveraging investments, by purchasing securities with borrowed money, is a speculative technique that increases investment risk, but also increases investment opportunity. Because substantially all of each Fund’s assets will fluctuate in value, whereas the interest obligations on borrowings may be fixed, the NAV of a Fund will increase more when such Fund’s portfolio assets increase in value and decrease more when the Fund’s portfolio assets decrease in value than would otherwise be the case. Moreover, interest costs on borrowings may fluctuate with changing market rates of interest and may partially offset or exceed the returns on the borrowed funds.

MORTGAGE DOLLAR ROLLS

A mortgage dollar roll is a transaction in which a fund sells mortgage-related securities for immediate settlement and simultaneously purchases the same type of securities for forward settlement at a discount. While a fund begins accruing interest on the newly purchased securities from the purchase or trade date, it is able to invest the proceeds from the sale of its previously owned securities, which will be used to pay for the new securities. The use of mortgage dollar rolls is a speculative technique involving leverage, and can have an economic effect similar to borrowing money for investment purposes.

MORTGAGE PASS-THROUGH SECURITIES

Each Fund may invest in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. government-sponsored enterprises: the Ginnie Mae, Fannie Mae or Freddie Mac. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome.

For the foregoing and other reasons, the Funds seek to obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to settlement date. A Fund may use TBA transactions in several ways. For example, a Fund may enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a TBA roll, a Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. In addition, a Fund may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities stipulated in the TBA agreement.

Default by or bankruptcy of a counterparty to a TBA transaction would expose a Fund to possible loss because of 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 Fund will enter into TBA transactions only with established counterparties (such as major broker-dealers) and the Adviser will monitor the creditworthiness of such counterparties. In addition, a Fund may accept assignments of TBA transactions from Authorized Participants (as defined below) from time to time. A Fund’s use of TBA rolls may cause such Fund to experience higher portfolio turnover, higher transaction costs and to pay higher capital gain distributions to shareholders (which may be taxable) than other funds.

The Funds intend to invest cash pending settlement of any TBA transactions in money market instruments, repurchase agreements, commercial paper (including asset-backed commercial paper) or other high-quality, liquid short-term instruments, which may include money market funds affiliated with the Adviser.

19

MUNICIPAL SECURITIES

General. Municipal securities are securities issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. Shareholders should note that, although interest paid on municipal securities is generally exempt from regular federal income tax, a Fund does not anticipate holding municipal securities in sufficient quantities to enable such Fund to qualify to pay exempt-interest dividends. As a result, distributions by the Fund to shareholders are expected to be treated for federal income tax purposes as ordinary dividends without regard to the character in the hands of the Fund of any interest that it receives on municipal securities.

Municipal securities share the attributes of debt/fixed income securities in general, but are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. The municipal securities which a Fund may purchase include general obligation bonds and limited obligation bonds (or revenue bonds), including industrial development bonds issued pursuant to former federal tax law. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Tax-exempt industrial development bonds generally are also revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the corporate user (and/or any guarantor).

Some longer-term municipal securities give the investor the right to “put” or sell the security at par (face value) within a specified number of days following the investor’s request—usually one to seven days. This demand feature enhances a security’s liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, a Fund would hold the longer-term security, which could experience substantially more volatility.

The market for municipal bonds may be less liquid than for taxable bonds. This means that it may be harder to buy and sell municipal securities, especially on short notice, than non-municipal securities. There may also be less information available on the financial condition of issuers of municipal securities than for public corporations. This means that it may be harder to buy and sell municipal securities, especially on short notice, and municipal securities may be more difficult for a Fund to value accurately than securities of public corporations. If a Fund invests in municipal securities, the Fund’s portfolio may have greater exposure to liquidity risk than a fund that only invests in non-municipal securities. In addition, the municipal securities market is generally characterized as a buy and hold investment strategy. As a result, the accessibility of municipal securities in the market is generally greater closer to the original date of issue of the securities and lessens as the securities move further away from such issuance date.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal security market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. In addition, municipal securities are subject to the risk that their tax treatment could be changed by Congress or state legislatures, thereby affecting the value of outstanding municipal securities. There is also the possibility that as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of a Fund’s municipal securities in the same manner.

Municipal Leases and Certificates of Participation. Also included within the general category of municipal securities are municipal leases, certificates of participation in such lease obligations or installment purchase contract obligations (hereinafter collectively called “Municipal Lease Obligations”) of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a

20

general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain “non-appropriation” clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a “non-appropriation” lease, a Fund’s ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and disposition or releasing of the property might prove difficult.

Municipal Insurance. A municipal security may be covered by insurance that guarantees the bond’s scheduled payment of interest and repayment of principal. This type of insurance may be obtained by either (i) the issuer at the time the bond is issued (primary market insurance), or (ii) another party after the bond has been issued (secondary market insurance).

Both primary and secondary market insurance guarantee timely and scheduled repayment of all principal and payment of all interest on a municipal security in the event of default by the issuer, and cover a municipal security to its maturity, enhancing its credit quality and value.

Municipal security insurance does not insure against market fluctuations or fluctuations in a Fund’s share price. In addition, a municipal security insurance policy will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond, or (iii) nonpayment of principal or interest caused by negligence or bankruptcy of the paying agent. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity.

Because a significant portion of the municipal securities issued and outstanding is insured by a small number of insurance companies, an event involving one or more of these insurance companies could have a significant adverse effect on the value of the securities insured by that insurance company and on the municipal markets as a whole.

Municipal Market Disruption Risk. The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of a bankruptcy. Proposals to restrict or eliminate the federal income tax exemption for interest on municipal securities are introduced before Congress from time to time. Proposals also may be introduced before state legislatures that would affect the state tax treatment of a municipal fund’s distributions. If such proposals were enacted, the availability of municipal securities and the value of any municipal securities held by a Fund would be affected. Municipal bankruptcies are relatively rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear and remain untested. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state. These legal uncertainties could affect the municipal securities market generally, certain specific segments of the market, or the relative credit quality of particular securities. Any of these effects could have a significant impact on the prices of some or all of the municipal securities held by a Fund.

OTHER SHORT-TERM INSTRUMENTS

Each Fund may invest in short-term instruments, including money market instruments, (including money market funds advised by the Adviser), cash and cash equivalents, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by the Adviser); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed time deposits and other obligations of U.S. and foreign banks (including foreign branches) and similar institutions; (iv) commercial paper rated at the date of purchase “Prime-1” by Moody’s Investors Service (“Moody’s”) or “A-1” by S&P, or if unrated, of comparable quality as determined by the Adviser; (v) non-convertible corporate debt securities ( e.g. , bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that present minimal credit risks; and (vi) short-term U.S. dollar-denominated obligations of foreign banks (including U.S. branches) that, in the opinion of the Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by a Fund. Any of these instruments may be purchased on a current or a forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions. Money market instruments also include shares of money market funds. The SEC and other government agencies continue to review the regulation of money market funds. The SEC has adopted changes to the rules that govern money market funds, and compliance with many of these amendments was required in October 2016. Legislative developments may also affect money market funds. These changes and developments may affect the investment strategies, performance, yield, operating expenses and continued viability of a money market fund.

21

PERPETUAL BONDS

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. An issuer of perpetual bonds is responsible for coupon payments in perpetuity but does not have to redeem the securities. Perpetual bonds may be callable after a set period of time. It is possible that one or more perpetual bonds in which a Fund invests will be characterized as equity rather than debt for U.S. federal income tax purposes. Where such perpetual bonds are issued by non-U.S. issuers, they may be treated in turn as equity securities of a “passive foreign investment company.”

PREFERRED SECURITIES

Preferred securities pay fixed or adjustable rate dividends to investors, and have “preference” over common stock in the payment of dividends and the liquidation of a company’s assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on preferred securities must be declared by the issuer’s board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accrue even if not declared by the board of directors or otherwise made payable. There is no assurance that dividends or distributions on the preferred securities in which a Fund invests will be declared or otherwise made payable.

The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws.

Because the claim on an issuer’s earnings represented by preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, a Fund’s holdings of higher rate-paying fixed rate preferred securities may be reduced and a Fund would be unable to acquire securities paying comparable rates with the redemption proceeds.

PRIVATE MORTGAGE PASS-THROUGH SECURITIES

Private mortgage pass-through securities are structured similarly to the Ginnie Mae, Fannie Mae and Freddie Mac mortgage pass-through securities and are issued by United States and foreign private issuers such as originators of and investors in mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks and special purpose subsidiaries of the foregoing. These securities usually are backed by a pool of conventional fixed rate or adjustable rate mortgage loans. Since private mortgage pass-through securities typically are not guaranteed by an entity having the credit status of Ginnie Mae, Fannie Mae and Freddie Mac, such securities generally are structured with one or more types of credit enhancement.

Mortgage Assets often consist of a pool of assets representing the obligations of a number of different parties. There are usually fewer properties in a pool of assets backing commercial mortgage-backed securities than in a pool of assets backing residential mortgage-backed securities hence they may be more sensitive to the performance of fewer Mortgage Assets. To lessen the effect of failures by obligors on underlying assets to make payments, those securities may contain elements of credit support, which fall into two categories: (i) liquidity protection and (ii) protection against losses resulting from ultimate default by an obligor on the underlying assets. Liquidity protection refers to the provision of advances, generally by the entity administering the pool of assets, to ensure that the receipt of payments on the underlying pool occurs in a timely fashion. Protection against losses resulting from default ensures ultimate payment of the obligations on at least a portion of the assets in the pool. This protection may be provided through guarantees, insurance policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches. The degree of credit support provided for each issue is generally based on historical information respecting the level of credit risk associated with the underlying assets. Delinquencies or losses in excess of those anticipated could adversely affect the return on an investment in a security.

QUALIFIED PUBLICLY TRADED PARTNERSHIPS

Regulated investment companies (“RICs”) are subject to favorable tax treatment under the Internal Revenue Code. To qualify as a RIC, each 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 investments in commodities is not qualifying income. Thus, income from certain commodities-related investments may cause a Fund not to qualify as a RIC. Each Fund may invest up to 25% of its total assets in one or more ETPs that are qualified publicly traded partnerships (“QPTPs”) and whose principal activities are the buying and selling of commodities or options, futures, or forwards with respect to commodities. Income from QPTPs is generally qualifying income. A QPTP is an entity that is treated as a partnership for federal income tax purposes, subject to certain requirements. If such an ETP fails to qualify as a QPTP, the income generated from a Fund’s investment in the ETP may not be qualifying income. A Fund will only invest in such an ETP if it intends to qualify as a QPTP, but there is no guarantee that each such 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,

22

and it is possible that future guidance may adversely affect the qualification of such ETPs as QPTPs. If a Fund fails to qualify as a RIC, the Fund itself will be subject to tax, which will reduce returns to the Fund’s shareholders. Such a failure will also alter the treatment of distributions to the Fund’s shareholders.

RATINGS

An investment-grade rating means the security or issuer is rated investment-grade by Moody’s, S&P, Fitch, Inc., Dominion Bond Rating Service Limited, or another credit rating agency designated as a nationally recognized statistical rating organization by the SEC, or is unrated but considered to be of equivalent quality by the Adviser or applicable Sub-Adviser.

Subsequent to purchase by a Fund, a rated security may cease to be rated or its investment grade rating may be reduced below an investment grade rating. Bonds rated lower than Baa3 by Moody’s or BBB- by S&P or Fitch are below investment grade quality and are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such securities (“lower rated securities”) are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Lower rated securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial. Bonds rated below investment grade tend to be less marketable than higher-quality bonds because the market for them is less broad. The market for unrated bonds is even narrower. See “HIGH YIELD SECURITIES” above for more information relating to the risks associated with investing in lower rated securities.

REAL ESTATE INVESTMENT TRUSTS (“REITs”)

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

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

REPURCHASE AGREEMENTS

Each Fund may invest in repurchase agreements with commercial banks, brokers or dealers to generate income from its excess cash balances and to invest securities lending cash collateral. A repurchase agreement is an agreement under which a fund acquires a financial instrument ( e.g. , a security issued by the U.S. government or an agency thereof, a banker’s acceptance or a certificate of deposit) from a seller, subject to resale to the seller at an agreed upon price and date (normally, the next Business Day – as defined below). A repurchase agreement may be considered a loan collateralized by securities. The resale price reflects an agreed upon interest rate effective for the period the instrument is held by a fund and is unrelated to the interest rate on the underlying instrument.

23

In these repurchase agreement transactions, the securities acquired by a fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and are held by the Custodian until repurchased. No more than an aggregate of 15% of a Fund’s net assets will be invested in illiquid securities, including repurchase agreements having maturities longer than seven days and securities subject to legal or contractual restrictions on resale, or for which there are no readily available market quotations.

The use of repurchase agreements involves certain risks. For example, if the other party to the agreement defaults on its obligation to repurchase the underlying security at a time when the value of the security has declined, a fund may incur a loss upon disposition of the security. If the other party to the agreement becomes insolvent and subject to liquidation or reorganization under the U.S. Bankruptcy Code or other laws, a court may determine that the underlying security is collateral for a loan by a fund not within the control of the fund and, therefore, the fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

RESTRICTED SECURITIES

Restricted securities are securities that are not registered under the Securities Act, but which can be offered and sold to “qualified institutional buyers” under Rule 144A under the Securities Act. Institutional markets for restricted securities have developed as a result of the promulgation of Rule 144A under the Securities Act, which provides a “safe harbor” from Securities Act registration requirements for qualifying sales to institutional investors. When Rule 144A restricted securities present an attractive investment opportunity and meet other selection criteria, a Fund may make such investments whether or not such securities are “illiquid” depending on the market that exists for the particular security. The Board has delegated the responsibility for determining the liquidity of Rule 144A restricted securities that a Fund may invest in to the Adviser. In reaching liquidity decisions, the Adviser may consider the following factors: the frequency of trades and quotes for the security; the number of dealers wishing to purchase or sell the security and the number of other potential purchasers; dealer undertakings to make a market in the security; and the nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

REVERSE REPURCHASE AGREEMENTS

Each Fund may enter into reverse repurchase agreements, which involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. The securities purchased with the funds obtained from the agreement and securities collateralizing the agreement will have maturity dates no later than the repayment date. Generally the effect of such transactions is that a fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases a fund is able to keep some of the interest income associated with those securities. Such transactions are only advantageous if a fund has an opportunity to earn a greater rate of interest on the cash derived from these transactions than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and a Fund intends to use the reverse repurchase technique only when the Adviser believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by securities having a value equal to or greater than such commitments. Under the 1940 Act, reverse repurchase agreements are considered borrowings. Although there is no limit on the percentage of fund assets that can be used in connection with reverse repurchase agreements, the Funds do not expect to engage, under normal circumstances, in reverse repurchase agreements with respect to more than 33 ^1/ ₃ % of their respective total assets.

SENIOR LOANS

The Income Allocation ETF, through its investment in an underlying exchange-traded product (the “Underlying Fund”), may receive exposure to first lien senior secured floating rate bank loans (“Senior Loans”). Senior Loans consist generally of obligations of companies and other entities (collectively, “borrowers”) incurred for the purpose of reorganizing the assets and liabilities of a borrower; acquiring another company; taking over control of a company (leveraged buyout); temporary refinancing; or financing internal growth or other general business purposes. Senior Loans are often obligations of borrowers who have incurred a significant percentage of debt compared to their total assets and thus are highly leveraged. The Underlying Fund does not treat the banks originating or acting as agents for the lenders, or granting or acting as intermediary in participation interests, in loans held by the Underlying Fund as the issuers of such loans.

Senior Loans may be acquired by direct investment as a lender at the inception of the loan or by assignment of a portion of a loan previously made to a different lender or by purchase of a participation interest. If the Fund makes a direct investment in a Senior Loan as one of the lenders, it generally acquires the loan at or below par. This means the Underlying Fund receives a return at or above the full interest rate for the loan. If the Underlying Fund acquires its interest in Senior Loans in the secondary market or acquires a participation interest, the loans may be purchased or sold above, at, or below par, which can result in a yield that is below, equal to, or above the stated interest rate of the loan. At times, the Underlying Fund may be able to invest in Senior Loans only through assignments or participations.

When the Underlying Fund is a purchaser of an assignment, it succeeds to all the rights and obligations under the loan agreement of the assigning lender and becomes a lender under the loan agreement with the same rights and obligations as the assigning lender. These rights include the ability to vote along with the other lenders on such matters as enforcing the terms of the loan agreement ( e.g. , declaring defaults, initiating collection actions, etc.). Taking such actions typically requires at least a vote of the lenders holding a majority of the investment in the loan and may require a vote by lenders holding two-thirds or more of the investment in the loan. Because the Underlying Fund usually does not hold a majority of the investment in any loan, it will not be able by itself to control decisions that require a vote by the lenders.

The Underlying Fund may, but will not typically, invest in Senior Loans through participations. A participation interest represents a fractional interest in a loan held by the lender selling the Underlying Fund the participation interest. In the case of participations, the Underlying Fund will not have any direct contractual relationship with the borrower, the Underlying Fund’s rights to consent to modifications of the loan are limited and it is dependent upon the participating lender to enforce the Underlying Fund’s rights upon a default. The Underlying Fund will have the right to receive payments of principal, interest, and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. The Underlying Fund will only purchase participations from lenders with credit ratings of Baa3 or higher by Moody’s or BBB- or higher by S&P or Fitch, or a comparable rating by another nationally recognized rating agency.

The Underlying Fund may be affected by the credit of both the agent and the lender from whom the Underlying Fund acquires a participation interest. These credit risks may include delay in receiving payments of principal and interest paid by the borrower to the agent or by the agent to the lender or offsets against payments received from the borrower. In the event of the borrower’s bankruptcy, the borrower’s obligation to repay the loan may be subject to defenses that the borrower can assert as a result of improper conduct by the agent.

Historically, the amount of public information available about a specific Senior Loan has been less extensive than if the loan were registered or exchange-traded.

The loans in which the Underlying Fund will invest will, in most instances, be Senior Loans, which are secured and senior to other indebtedness of the borrower. Each Senior Loan will generally be secured by collateral such as accounts receivable, inventory, equipment, real estate, intangible assets such as trademarks, copyrights and patents, and securities of subsidiaries or affiliates. The value of the collateral generally will be determined by reference to financial statements of the borrower, by an independent appraisal, by obtaining the market value of such collateral,

24

in the case of cash or securities if readily ascertainable, or by other customary valuation techniques considered appropriate by the Adviser. The value of collateral may decline after the Underlying Fund’s investment, and collateral may be difficult to sell in the event of default. Consequently, the Underlying Fund may not receive all the payments to which it is entitled. By virtue of their senior position and collateral, Senior Loans typically provide lenders with the first right to cash flows or proceeds from the sale of a borrower’s collateral if the borrower becomes insolvent (subject to the limitations of bankruptcy law, which may provide higher priority to certain claims such as employee salaries, employee pensions, and taxes). This means Senior Loans are generally repaid before unsecured bank loans, corporate bonds, subordinated debt, trade creditors, and preferred or common stockholders. To the extent that the Underlying Fund invests in unsecured loans, if the borrower defaults on such loan, there is no specific collateral on which the lender can foreclose. If the borrower defaults on a subordinated loan, the collateral may not be sufficient to cover both the senior and subordinated loans.

Senior Loans will usually require, in addition to scheduled payments of interest and principal, the prepayment of the Senior Loan from free cash flow, as further described below. The degree to which borrowers prepay Senior Loans, whether as a contractual requirement or at their election, may be affected by general business conditions, the financial condition of the borrower and competitive conditions among loan investors, among others. As such, prepayments cannot be predicted with accuracy. Certain market conditions, including those where default rates are falling, among others, may lead to increased prepayment frequency and loan renegotiations. These renegotiations are often on terms more favorable to borrowers. Upon a prepayment, either in part or in full, the actual outstanding debt on which the Underlying Fund derives interest income will be reduced. However, the Underlying Fund may receive a prepayment penalty fee assessed against the prepaying borrower.

Senior Loans typically pay interest at least quarterly at rates which equal a fixed percentage spread over a base rate such as the LIBOR. For example, if LIBOR were 0.3% and the borrower was paying a fixed spread of 2.50%, the total interest rate paid by the borrower would be 2.80%. Additionally, many Senior Loans also have a minimum base rate, or floor, which will be used if the actual base rate is below this minimum base rate. This measure is designed to ensure lenders receive a minimum interest rate in periods of low interest rates. By illustration, if LIBOR were 0.3% and the borrower was paying a fixed spread of 2.50%, the total interest rate paid by the borrower would be 2.80%. However, if the same Senior Loan had a LIBOR floor of 1.50%, then 1.50% would be used as the base rate notwithstanding that LIBOR was currently at 0.3%, thereby making the interest rate paid the borrower 4.00% (1.50% LIBOR floor base rate plus 2.50% fixed spread). During periods when LIBOR is greater than the LIBOR floor, the LIBOR floor would have no impact on the interest rate paid by the borrower. Not all Senior Loans have LIBOR floors and this feature may not persist in future issuances of Senior Loans.

Although a base rate such as LIBOR can change every day, loan agreements for Senior Loans typically allow the borrower the ability to choose how often the base rate for its loan will reset. A single loan may have multiple reset periods at the same time, with each reset period applicable to a designated portion of the loan. Such reset periods can range from one day to one year, with most borrowers choosing monthly or quarterly reset periods. During periods of rising interest rates, borrowers will tend to choose longer reset periods, and during periods of declining interest rates, borrowers will tend to choose shorter reset periods.

Senior Loans generally are arranged through private negotiations between a borrower and several financial institutions represented by an agent who is usually one of the originating lenders. In larger transactions, it is common to have several agents; however, generally only one such agent has primary responsibility for ongoing administration of a Senior Loan. Agents are typically paid fees by the borrower for their services.

The administrative agent is primarily responsible for negotiating the loan agreement which establishes the terms and conditions of the Senior Loan and the rights of the borrower and the lenders. The collateral agent is responsible for monitoring collateral and for exercising remedies available to the lenders such as foreclosure upon collateral. Any applicable Sub-Adviser or its affiliates may from time to time borrow from financial institutions that act as agents for loans.

Loan agreements may provide for the termination of the agent’s agency status in the event that it fails to act as required under the relevant loan or collateral agreement, becomes insolvent, enters Federal Deposit Insurance Corporation (“FDIC”) receivership or, if not FDIC insured, enters into bankruptcy. Should such an agent, lender or assignor with respect to an assignment interpositioned between the Underlying Fund and the borrower become

25

insolvent or enter FDIC receivership or bankruptcy, any interest in the Senior Loan of such person and any loan payment held by such person for the benefit of the Underlying Fund should not be included in such person’s or entity’s bankruptcy estate. If, however, any such amount were included in such person’s or entity’s bankruptcy estate, the Underlying Fund would incur certain costs and delays in realizing payment or could suffer a loss of principal or interest. In this event, the Underlying Fund and, therefore, the Fund could experience a decrease in the NAV.

Most borrowers pay their debts from cash flow generated by their businesses. If a borrower’s cash flow is insufficient to pay its debts, it may attempt to restructure its debts rather than sell collateral. Borrowers may try to restructure their debts by filing for protection under the federal bankruptcy laws or negotiating a work-out. If a borrower becomes involved in a bankruptcy proceeding, access to collateral may be limited by bankruptcy and other laws. Such action by a court could be based, for example, on a “fraudulent conveyance” claim to the effect that the borrower did not receive fair consideration for granting the security interest in the loan collateral to the Underlying Fund. If a court decides that access to collateral is limited or void, the Underlying Fund may not recover the full amount of principal and interest that is due.

A borrower must comply with certain restrictive covenants contained in the loan agreement. In addition to requiring the scheduled payment of principal and interest, these covenants may include restrictions on the payment of dividends and other distributions to the borrower’s shareholders, provisions requiring compliance with specific financial ratios, and limits on total indebtedness. The agreement may also require the prepayment of the loans from excess cash flow. A breach of a covenant that is not waived by the agent (or lenders directly) is normally an event of default, which provides the agent and lenders the right to call for repayment of the outstanding loan. The typical practice of an agent or a loan investor in relying exclusively or primarily on reports from the borrower to monitor the borrower’s compliance with covenants may involve a risk of fraud by the borrower.

In the process of buying, selling and holding Senior Loans, the Underlying Fund may receive and/or pay certain fees. These fees are in addition to interest payments received and may include facility fees, commitment fees, commissions and prepayment penalty fees. When the Underlying Fund buys or sells a Senior Loan it may pay an assignment fee. On an ongoing basis, the Underlying Fund may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a Senior Loan. In certain circumstances, the Underlying Fund may receive a prepayment penalty fee upon prepayment of a Senior Loan. Other fees received by the Underlying Fund may include covenant waiver fees, covenant modification fees or other consent or amendment fees.

Notwithstanding its intention in certain situations to not receive material, non-public information with respect to its management of investments in Senior Loans, the Adviser and/or applicable Sub-Adviser may from time to time come into possession of material, non-public information about the issuers of loans that may be held in the Underlying Fund’s portfolio. Possession of such information may in some instances occur despite the Adviser’s and/or applicable Sub-Adviser’s efforts to avoid such possession, but in other instances the Adviser and/or applicable Sub-Adviser may choose to receive such information (for example, in connection with participation in a creditors’ committee with respect to a financially distressed issuer). The Adviser’s and/or applicable Sub-Adviser’s ability to trade in these Senior Loans for the account of the Underlying Fund could potentially be limited by its possession of such information. Such limitations on the Adviser’s and/or applicable Sub-Adviser’s ability to trade could have an adverse effect on the Underlying Fund by, for example, preventing the Underlying Fund from selling a Senior Loan that is experiencing a material decline in value. In some instances, these trading restrictions could continue in effect for a substantial period of time.

The loan market, as represented by the S&P/LSTA (Loan Syndications and Trading Association) Leveraged Loan Index, experienced significant growth in terms of number and aggregate volume of loans outstanding since the inception of the index in 1997. In 1997, the total amount of loans in the market aggregated less than $10 billion. By April of 2000, it had grown to over $100 billion, and by July of 2007 the market had grown to over $500 billion, expanding further to a pre-crisis peak of $594 billion in November 2008. Throughout this period, the demand for loans and the number of investors participating in the loan market also increased significantly.

From November 2008 to July 2010 the aggregate size of the loan market contracted approximately 15%, but has since continued to grow to $930 billion in size as of August 2017. The number of market participants has also increased to above pre-crisis levels. There can be no assurance that the size of the loan market, and the number of participants, will sustain such levels.

26

An increase in demand for Senior Loans may benefit the Underlying Fund by providing increased liquidity for such loans and higher sales prices, but it may also adversely affect the rate of interest payable on such loans acquired by the Underlying Fund and the rights provided to the Underlying Fund under the terms of the applicable loan agreement, and may increase the price of loans that the Underlying Fund wishes to purchase in the secondary market. A decrease in the demand for Senior Loans may adversely affect the price of loans in the Underlying Fund’s portfolio, which could cause the Underlying Fund’s and, therefore, the Fund’s net asset value to decline.

The Underlying Fund may acquire interests in Senior Loans which are designed to provide temporary or “bridge” financing to a borrower pending the sale of identified assets or the arrangement of longer-term loans or the issuance and sale of debt obligations. The Underlying Fund may also invest in Senior Loans of borrowers that have obtained bridge loans from other parties. A borrower’s use of bridge loans involves a risk that the borrower may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. Bridge loans may have less liquidity than other Senior Loans that were issued to fund corporate purposes on a longer term basis.

Although not anticipated in the normal course, the Underlying Fund may occasionally acquire warrants and other equity securities as part of a unit combining a Senior Loan and equity securities of a borrower or its affiliates. The acquisition of such equity securities will only be incidental to the Underlying Fund’s purchase of a Senior Loan. The Underlying Fund may also acquire equity securities or credit securities (including non-dollar denominated equity or credit securities) issued in exchange for a Senior Loan or issued in connection with the debt restructuring or reorganization of a Borrower, or if such acquisition, in the judgment of the Adviser may enhance the value of a Senior Loan or would otherwise be consistent with the Underlying Fund’s investment policies. Such warrants and equity securities will typically have limited value and there is no assurance that such securities will ever obtain value.

Other loans. The Underlying Fund may invest in secured loans that are not first lien and loans that are unsecured. These loans have the same characteristics as Senior Loans except that such loans are not first in priority of repayment and/or are not secured by collateral. Accordingly, the risks associated with these loans are higher than the risks for loans with first priority over the collateral. Because these loans are lower in priority and/or unsecured, they are subject to the additional risk that the cash flow of the borrower may be insufficient to meet scheduled payments after giving effect to the secured obligations of the borrower. In the event of default on such a loan, the first priority lien holder has first claim to the underlying collateral of the loan. It is possible that no value would remain for the holders of secured loans that are not first lien and loans that are unsecured and therefore result in a loss of investment to the Underlying Fund.

Secured loans that are not first lien and loans that are unsecured generally have greater price volatility than Senior Loans and may be less liquid. There is also a possibility that originators will not be able to sell participations in these loans, which would create greater credit risk exposure for the holders of such loans. Secured loans that are not first lien and loans that are unsecured share the same risks as other below investment grade instruments.

SOVEREIGN DEBT OBLIGATIONS

Sovereign debt obligations are issued or guaranteed by foreign governments or their agencies. Sovereign debt may be in the form of conventional securities or other types of debt instruments such as loans or loan participations. Governmental entities responsible for repayment of the debt may be unable or unwilling to repay principal and pay interest when due, and may require renegotiation or reschedule of debt payments. In addition, prospects for repayment of principal and payment of interest may depend on political as well as economic factors. Although some sovereign debt, such as Brady Bonds, is collateralized by U.S. government securities, repayment of principal and payment of interest is not guaranteed by the U.S. government.

STRIPPED MORTGAGE SECURITIES

Stripped mortgage securities may be issued by Federal Agencies, or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks and special purpose subsidiaries of the foregoing. Stripped mortgage securities not issued by Federal Agencies will be treated by a Fund as illiquid securities so long as the staff of the SEC maintains its position that such securities are illiquid. Stripped mortgage securities issued by Federal Agencies generally will be treated by a Fund as liquid securities under procedures adopted by the Fund and approved by the Fund’s Board.

27

Stripped mortgage securities usually are structured with two classes that receive different proportions of the interest and principal distribution of a pool of mortgage assets. A common type of stripped mortgage security will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the interest-only or “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). PO classes generate income through the accretion of the deep discount at which such securities are purchased, and, while PO classes do not receive periodic payments of interest, they receive monthly payments associated with scheduled amortization and principal prepayment from the mortgage assets underlying the PO class. The yield to maturity on a PO or an IO class security is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets. A slower than expected rate of principal payments may have an adverse effect on a PO class security’s yield to maturity. If the underlying mortgage assets experience slower than anticipated principal repayment, a Fund may fail to fully recoup its initial investment in these securities. Conversely, a rapid rate of principal payments may have a material adverse effect on an IO class security’s yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments or principal, a Fund may fail to fully recoup its initial investment in these securities.

A Fund may purchase stripped mortgage securities for income, or for hedging purposes to protect the Fund against interest rate fluctuations. For example, since an IO class will tend to increase in value as interest rates rise, it may be utilized to hedge against a decrease in value of other fixed-income securities in a rising interest rate environment.

U.S. GOVERNMENT OBLIGATIONS

U.S. government obligations are a type of bond. U.S. government obligations include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities.

One type of U.S. government obligation, U.S. Treasury obligations, are backed by the full faith and credit of the U.S. Treasury and differ only in their interest rates, maturities, and times of issuance. U.S. Treasury bills have initial maturities of one-year or less; U.S. Treasury notes have initial maturities of one to ten years; and U.S. Treasury bonds generally have initial maturities of greater than ten years.

28

Other U.S. government obligations are issued or guaranteed by agencies or instrumentalities of the U.S. government including, but not limited to, Federal National Mortgage Association (“Fannie Mae”), the Government National Mortgage Association (“Ginnie Mae”), the Small Business Administration, the Federal Farm Credit Administration, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal Home Loan Banks (“FHLB”), Banks for Cooperatives (including the Central Bank for Cooperatives), the Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation (Farmer Mac). Some obligations issued or guaranteed by U.S. government agencies and instrumentalities, including, for example, Ginnie Mae pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by Fannie Mae, are supported by the discretionary authority of the U.S. government to purchase certain obligations of the federal agency, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury. While the U.S. government provides financial support to such U.S. government-sponsored federal agencies, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law.

In September 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. Under the terms of the takeover, the U.S. Treasury agreed to acquire $1 billion of senior preferred stock of each instrumentality and obtained warrants for the purchase of common stock of each instrumentality. Under these Senior Preferred Stock Purchase Agreements (“SPAs”), the U.S. Treasury has pledged to provide a limited amount of capital per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their assets. In May 2009, the U.S. Treasury increased its maximum commitment to each instrumentality under the SPAs from $100 billion to $200 billion per instrumentality. In December 2009, the U.S. Treasury amended the SPAs to provide Fannie Mae and Freddie Mac with some additional flexibility to meet the requirement to reduce their mortgage portfolios. Also in December 2009, the U.S. Treasury further amended the SPAs to allow the cap on the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in Fannie Mae’s and Freddie Mac’s net worth through the end of 2012. On August 17, 2012, the U.S. Treasury announced that it was again amending the Agreement to terminate the requirement that Fannie Mae and Freddie Mac each pay a 10% dividend annually on all amounts received under the funding commitment. Instead, they will transfer to the U.S. Treasury on a quarterly basis all profits earned during a quarter that exceed a capital reserve amount of $3 billion. The U.S. Treasury stated that the purpose of the change was to wind down Freddie Mac and Fannie Mae and to benefit taxpayers. At the start of 2013, the unlimited support the U.S. Treasury extended to the two companies expired — Fannie Mae’s bailout is now capped at $125 billion and Freddie Mac has a limit of $149 billion. In August 2013, President Obama announced his proposal to shut down Freddie Mac and Fannie Mae as part of a plan to overhaul the U.S.’s mortgage finance system. Until further action is taken, the actions of the U.S. Treasury are intended to ensure that Fannie Mae and Freddie Mac maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. No assurance can be given that the U.S. Treasury initiatives will be successful.

U.S. REGISTERED SECURITIES OF FOREIGN ISSUERS

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

A Fund’s investments in common stock of foreign corporations may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, which evidence ownership of underlying securities issued by a foreign corporation. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a foreign issuer. For other Depositary Receipts, the depository may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary Receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designated for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. The SPDR DoubleLine Total Return Tactical ETF may invest in sponsored or unsponsored ADRs; however, not more than 10% of the net assets of the SPDR DoubleLine Total Return Tactical ETF will be invested in unsponsored ADRs. The issuers of unsponsored ADRs are not obligated to disclose material information in the United States, and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the ADRs.

VARIABLE AND FLOATING RATE SECURITIES

Variable rate securities are instruments issued or guaranteed by entities such as (1) US government, or an agency or instrumentality thereof, (2) states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-states agencies or authorities, (3) corporations, (4) financial institutions, (5) insurance companies or (6) trusts that have a rate of interest subject to adjustment at regular intervals but less frequently than annually. A variable rate security provides for the automatic establishment of a new interest rate on set dates. Variable rate obligations whose interest is readjusted no less frequently than annually will be deemed to have a maturity equal to the period remaining until the next readjustment of the interest rate. Each Fund may also purchase floating rate securities. A floating rate security provides for the automatic adjustment of its interest rate whenever a specified interest rate changes. Interest rates on these securities are ordinarily tied to, and are a percentage of, a widely recognized interest rate, such as the yield on 90-day US Treasury bills or the prime rate of a specified bank. These rates may change as often as twice daily. Generally, changes in interest rates will have a smaller effect on the market value of variable and fixed rate floating rate securities than on the market value of comparable fixed rate fixed income obligations. Thus, investing in variable and fixed rate floating rate securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed rate fixed income securities.

VARIABLE RATE DEMAND OBLIGATIONS

Variable Rate Demand Obligations (“VRDOs”) are short-term tax exempt fixed income instruments whose yield is reset on a periodic basis. VRDO securities tend to be issued with long maturities of up to 30 or 40 years; however, they are considered short-term instruments because they include a put feature which coincides with the periodic yield reset. For example, a VRDO whose yield resets weekly will have a put feature that is exercisable upon seven days’ notice. VRDOs are put back to a bank or other entity that serves as a liquidity provider, who then tries to resell the VRDOs or, if unable to resell, holds them in its own inventory. VRDOs are generally supported by either a Letter of Credit or a Stand-by Bond Purchase Agreement to provide credit enhancement.

SPECIAL CONSIDERATIONS AND RISKS

A discussion of the risks associated with an investment in each Fund is contained in the Prospectus. The discussion below supplements, and should be read in conjunction with, the Prospectus.

GENERAL

Investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of securities generally and other factors.

An investment in a Fund should also be made with an understanding of the risks inherent in an investment in securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the securities markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of Shares). Securities are susceptible to general market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic and banking crises. Securities of issuers traded on exchanges may be suspended on certain exchanges by the issuers themselves, by an exchange or by government authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and instruments that reference the securities, such as participatory notes (or “P-notes”) or other derivative instruments, may be halted.

Holders of common stocks incur more risk than holders of preferred stocks and debt obligations because common stockholders, as owners of the issuer, have generally inferior rights to receive payments from the issuer in comparison with the rights of creditors of, or holders of debt obligations or preferred stocks issued by, the issuer. Further, unlike debt securities which typically have a stated principal amount payable at maturity (whose value, however, will be subject to market fluctuations prior thereto), or preferred stocks which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity. Common stock values are subject to market fluctuations as long as the common stock remains outstanding.

30

The principal trading market for some securities may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of a Fund’s Shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent or if bid/ask spreads are wide.

CHINA A SHARE RISK

Certain Funds may be subject to risks associated with investments in A Shares of Chinese issuers (“China A Shares” or “A Shares”). The Funds may invest in A Shares through the Hong Kong-Shanghai Stock Connect or Shenzhen-Hong Kong Stock Connect programs (the “Stock Connect program”).

Investing through the Stock Connect Program

A Fund may invest in eligible securities listed and traded on the Shanghai Stock Exchange (“SSE”) or Shenzhen Stock Exchange through the Stock Connect program, a securities trading and clearing program developed by The Stock Exchange of Hong Kong Limited (“SEHK”), SSE and Shenzhen Stock Exchange, Hong Kong Securities Clearing Company Limited (“HKSCC”) and China Securities Depository and Clearing Corporation Limited for the establishment of mutual market access between The Stock Exchange of Hong Kong Limited and the SSE and Shenzhen Stock Exchange. Among other restrictions, investors in securities obtained via the Stock Connect program are generally subject to Chinese securities regulations and SSE or Shenzhen Stock Exchange rules. Securities obtained via the Stock Connect program generally may only be sold, purchased or otherwise transferred through the Stock Connect program in accordance with applicable rules. The Stock Connect program is recently-established and further developments are likely. There can be no assurance as to whether or how such developments may restrict or affect a Fund’s investments or returns. In addition, the application and interpretation of the laws and regulations of Hong Kong and the People’s Republic of China (the “PRC”), and the rules, policies or guidelines published or applied by relevant regulators and exchanges in respect of the Stock Connect program, are uncertain, and they may have a detrimental effect on a Fund’s investments and returns. The securities eligible to be traded by a Fund through the Stock Connect program are subject to change.

Ownership of A Shares Risk. A Shares acquired by Hong Kong and foreign investors, including each Fund, through the Stock Connect program are held by HKSCC as the “nominee holder” of such A Shares. A nominee holder is the person who holds securities on behalf of an underlying investor, or “beneficial owner,” who is entitled to the rights and benefits of the SSE or Shenzhen Stock Exchange securities acquired through the Stock Connect program. he precise nature and rights of an investor as the beneficial owner of A Shares acquired through the Stock Connect program and held by HKSCC as nominee holder is not well defined under PRC law and it is not yet clear that such rights can be successfully enforced.

Quota Limitations Risk. Although a Fund’s investments through the Stock Connect program, if any, are not subject to individual investment quotas, daily investment quotas apply to all participants in the Stock Connect program. Trading through the Stock Connect program is subject to daily quotas (“Daily Quotas”). The Daily Quotas differ for Hong Kong and foreign investors (including the Funds) trading into Mainland China (“Northbound Trading”) and PRC investors trading into Hong Kong (“Southbound Trading”). The Daily Quotas are applicable to trading activity transacted through the Stock Connect program and are monitored by the SEHK. The Daily Quota limits the maximum net buy value of cross-border trades via Northbound Trading through the Stock Connect program each day. The Daily Quotas may change throughout the trading day and consequently affect a Fund’s ability to trade through the Stock Connect program at any given time during a trading day. In particular, once the remaining balance of the Daily Quota applicable to Northbound Trading drops to zero or such Daily Quota is exceeded, new buy orders will be rejected (though investors will be allowed to sell their A Shares regardless of the quota balance). Therefore, quota limitations may restrict or limit a Fund’s ability to invest in A Shares through the Stock Connect program on a timely basis or at all on any given day.

Restriction on Day Trading Risk. Day (turnaround) trading is not permitted through the Stock Connect program. Investors buying A Shares on day T can only sell the shares on and after day T+1 subject to any Stock Connect program rules.

A Share Market Suspension Risk. A Shares may only be purchased from, or sold to, a Fund from time to time where the relevant A Shares may be sold or purchased on the SSE or the Shenzhen Stock Exchange, as appropriate. Securities exchanges in the PRC typically have the right to suspend or limit trading in any security traded on the relevant exchange.

Additional Clearing, Settlement and Custody Risk. Trading via the Stock Connect program is subject to trading, clearance and settlement procedures that are relatively untested in China, which could pose risks to a Fund. A Fund’s investments through Northbound Trading are currently not covered by the Hong Kong Investor Compensation Fund.

31

Additional Operational Risk. The Stock Connect program is premised on the functioning of the operational systems of the relevant market participants. Market participants are able to participate in the Stock Connect program subject to meeting certain information technology capability, risk management and other requirements as may be specified by the relevant exchange and/or clearing house. Further, the “connectivity” in the Stock Connect program requires routing of orders across the border of Hong Kong and the PRC. This requires the development of new information technology systems on the part of the SEHK and Exchange Participants (i.e., China Stock Connect System). There is no assurance that the systems of the SEHK and market participants will function properly or will continue to be adapted to changes and developments in both markets. In the event that the relevant systems fail to function properly, trading in A Shares through the Stock Connect program could be disrupted. A Fund’s ability to access the A Share market through the Stock Connect program may be adversely affected.

Differences in Trading Day Risk. The Stock Connect program will only operate on days when both the PRC and Hong Kong markets are open for trading and when banks in both markets are open on the corresponding settlement days. So it is possible that there are occasions when it is a normal trading day for the PRC market but investors, including the Funds, cannot carry out any A Shares trading. A Fund may be subject to a risk of price fluctuations in A Shares during the time when the Stock Connect program is not trading as a result.

A Share Tax Risk. While overseas investors currently are exempt from paying capital gains or value added taxes on income and gains from investments in A Shares, these PRC tax rules could be changed, which could result in unexpected tax liabilities for a Fund.

General PRC-Related Risks

Economic, Political and Social Risks of the PRC. The economy of China, which has been in a state of transition from a planned economy to a more market oriented economy, differs from the economies of most developed countries in many respects, including the level of government involvement, its state of development, its growth rate, control of foreign exchange, protection of intellectual property rights and allocation of resources.

Although the majority of productive assets in China are still owned by the PRC government at various levels, in recent years, the PRC government has implemented economic reform measures emphasizing utilization of market forces in the development of the economy of China and a high level of management autonomy. The economy of China has experienced significant growth in the past several decades, but growth has been uneven both geographically and among various sectors of the economy, and no assurance can be given that such growth will continue. Economic growth has also been accompanied by periods of high inflation. The PRC government has implemented various measures from time to time to control inflation and restrain the rate of economic growth.

There can, however, be no assurance that the PRC government will continue to pursue such economic policies or, if it does, that those policies will continue to be successful. Any such adjustment and modification of those economic policies may have an adverse impact on the securities markets in the PRC as well as the portfolio securities of a Fund. Further, the PRC government may from time to time adopt corrective measures to control the growth of the PRC economy, which may also have an adverse impact on the capital growth and performance of a Fund. Political changes, social instability and adverse diplomatic developments in the PRC could result in the imposition of additional government restrictions, including expropriation of assets, confiscatory taxes, limits on repatriation, or nationalization of some or all of the property held by the underlying issuers of a Fund’s portfolio securities.

PRC Laws and Regulations Risk. The regulatory and legal framework for capital markets and joint stock companies in the PRC may not be as well developed as those of developed countries. PRC laws and regulations affecting securities markets are relatively new and evolving, and because of the limited volume of published cases and judicial interpretation and their non-binding nature, interpretation and enforcement of these regulations involve significant uncertainties. In addition, as the PRC legal system develops, no assurance can be given that changes in such laws and regulations or new laws, regulations or practices relating to transactions in Chinese securities will be promulgated, or that their interpretation or enforcement will not have a material adverse effect on a Fund’s portfolio securities.

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. A Fund may invest in other pooled investment vehicles sponsored, managed, or otherwise affiliated with the Adviser. There is no assurance that the rates at which 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.

32

CONTINUOUS OFFERING

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by the Trust on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares, and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus-delivery obligation with respect to Shares of a Fund are reminded that under Securities Act Rule 153, a prospectus-delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Exchange is satisfied by the fact that a Fund’s Prospectus is available at the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

COUNTERPARTY RISK

Counterparty risk with respect to derivatives has been and may continue to be affected by new rules and regulations affecting the derivatives market. Some derivatives transactions are required to be centrally cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position, rather than the credit risk of its original counterparty to the derivatives transaction. Credit risk of market participants with respect to derivatives that are centrally cleared is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted, what effect the insolvency proceeding would have on any recovery by a Fund, and what impact an insolvency of a clearing house would have on the financial system more generally.

FUTURES AND OPTIONS TRANSACTIONS

There can be no assurance that a liquid secondary market will exist for any particular futures contract or option at any specific time. Thus, it may not be possible to close a futures or options position. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to make delivery of the instruments underlying futures contracts it has sold.

A Fund will minimize the risk that it will be unable to close out a futures or options contract by only entering into futures and options for which there appears to be a liquid secondary market.

The risk of loss in trading futures contracts or uncovered call options in some strategies ( e.g. , selling uncovered index futures contracts) is potentially unlimited. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. 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. A Fund, however, may utilize futures and options contracts in a manner designed to limit its risk exposure to that which is comparable to what it would have incurred through direct investment in securities.

Utilization of futures transactions by a Fund involves the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option.

Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

33

RISKS OF SWAP AGREEMENTS

Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, a Fund will have contractual remedies pursuant to the agreements related to the transaction, but such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor.

The use of interest-rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. The use of a swap requires an understanding not only of the referenced asset, reference rate or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

The absence of a regulated execution facility or contract market and lack of liquidity for swap transactions has led, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions. Under recently adopted rules and regulations, transactions in some types of swaps are required to be centrally cleared. In a cleared derivatives transaction, a Fund’s counterparty to the transaction is a central derivatives clearing organization, or clearing house, rather than a bank or broker. Because each Fund is not a member of a clearing house, and only members of a clearing house can participate directly in the clearing house, the Fund holds cleared derivatives through accounts at clearing members. In cleared derivatives transactions, a Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house. Centrally cleared derivative arrangements may be less favorable to a Fund than bilateral (non-cleared) arrangements. For example, a Fund may be required to provide greater amounts of margin for cleared derivatives transactions than for bilateral derivatives transactions. Also, in contrast to bilateral derivatives transactions, in some cases following a period of notice to a Fund, a clearing member generally can require termination of existing cleared derivatives transactions at any time or an increase in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions or to terminate transactions at any time. A Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or which SSGA FM expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of the transaction, including loss of an increase in the value of the transaction and loss of hedging protection. In addition, the documentation governing the relationship between a Fund and clearing members is drafted by the clearing members and generally is less favorable to the Fund than typical bilateral derivatives documentation.

These clearing rules and other new rules and regulations could, among other things, restrict a Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. These regulations are new and evolving, so their potential impact on a Fund and the financial system are not yet known.

Because they are two party contracts that may be subject to contractual restrictions on transferability and termination and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid and subject to a Fund’s limitation on investments in illiquid securities. To the extent that a swap is not liquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. Like most other investments, swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to a Fund’s interest.

If a Fund uses a swap as a hedge against, or as a substitute for, a portfolio investment, the Fund will be exposed to the risk that the swap will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the Fund. While hedging strategies involving swap instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other portfolio investments. Many swaps are complex and often valued subjectively.

TAX RISKS

As with any investment, you should consider how your investment in Shares of a Fund will be taxed. The tax information in the Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares of a Fund.

Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when a Fund makes distributions or you sell Shares.

34

INVESTMENT RESTRICTIONS

The Trust has adopted the following investment restrictions as fundamental policies with respect to each Fund. These restrictions cannot be changed with respect to a Fund without the approval of the holders of a majority of the Fund’s outstanding voting securities. For purposes of the 1940 Act, a majority of the outstanding voting securities of a Fund means the vote, at an annual or a special meeting of the security holders of the Trust, of the lesser of (1) 67% or more of the voting securities of the Fund present at such meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (2) more than 50% of the outstanding voting securities of the Fund. Except with the approval of a majority of the outstanding voting securities, a Fund may not:

1. (Except SPDR SSGA Ultra Short Term Bond ETF and SPDR DoubleLine Total Return Tactical ETF) Purchase securities of an issuer that would cause the Fund to fail to satisfy the diversification requirement for a diversified management company under the 1940 Act, the rules or regulations thereunder or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time;

2. Concentrate investments in a particular industry or group of industries, as concentration is defined under the 1940 Act, the Rules and regulations thereunder or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time; ¹

3. Make loans to another person except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Funds;

4. Issue senior securities or borrow money except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Funds;

5. Invest directly in real estate unless the real estate is acquired as a result of ownership of securities or other instruments. This restriction shall not preclude a Fund from investing in companies that deal in real estate or in instruments that are backed or secured by real estate;

6. Act as an underwriter of another issuer’s securities, except to the extent the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 in connection with the Fund’s purchase and sale of portfolio securities; or

7. Invest in commodities except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Funds.

In addition to the investment restrictions adopted as fundamental policies as set forth above, each Fund observes the following restrictions, which may be changed by the Board without a shareholder vote. A Fund will not:

1. Invest in the securities of a company for the purpose of exercising management or control, provided that the Trust may vote the investment securities owned by the Fund in accordance with its views;

2. Hold illiquid assets in excess of 15% of its net assets. An illiquid asset is any asset which may not be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the Fund has valued the investment;

3. With respect to the SPDR SSGA Ultra Short Term Bond ETF, under normal circumstances, invest less than 80% of its net assets (plus the amount of borrowings for investment purposes) in debt securities. Prior to any change in this 80% investment policy, the Fund will provide shareholders with 60 days’ written notice.

4. With respect to the MFS ETFs, under normal circumstances, invest less than 80% of a Fund’s net assets (plus the amount of borrowings for investment purposes) in equity securities. Prior to any change in this 80% investment policy, a Fund will provide shareholders with 60 days’ written notice.

If a percentage limitation is adhered to at the time of investment or contract, a later increase or decrease in percentage resulting from any change in value or total or net assets will not result in a violation of such restriction, except that the percentage limitations with respect to the borrowing of money and illiquid securities will be observed continuously. With respect to the limitation on borrowing,

35

in the event that a subsequent change in net assets or other circumstances cause a Fund to exceed its limitation, the Fund will take steps to bring the aggregate amount of borrowing back within the limitations within three days thereafter (not including Sundays and holidays). With respect to the limitation on illiquid securities, in the event that a subsequent change in net assets or other circumstances cause a Fund to exceed its limitation, the Fund will take steps to bring the aggregate amount of illiquid instruments back within the limitations as soon as reasonably practicable.

The 1940 Act currently permits each Fund to loan up to 33 1/3% of its total assets. With respect to borrowing, the 1940 Act presently allows each Fund to: (1) borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets, (2) borrow money for temporary purposes in an amount not exceeding 5% of the value of each Fund’s total assets at the time of the loan, and (3) enter into reverse repurchase agreements. However, under normal circumstances any borrowings by a Fund will not exceed 10% of a Fund’s total assets. The 1940 Act generally prohibits funds from issuing senior securities, although it does not treat certain transactions as senior securities, such as certain borrowings, short sales, reverse repurchase agreements, firm commitment agreements and standby commitments, with appropriate earmarking or segregation of assets to cover such obligation. With respect to investments in commodities, the 1940 Act presently permits each Fund to invest in commodities in accordance with investment policies contained in its prospectus and SAI. Any such investment shall also comply with the CEA and the rules and regulations thereunder. The 1940 Act does not directly restrict an investment company’s ability to invest in real estate, but does require that every investment company have the fundamental investment policy governing such investments. A Fund will not purchase or sell real estate, except that the Fund may invest in companies that deal in real estate (including REITs) or in instruments that are backed or secured by real estate.

EXCHANGE LISTING AND TRADING

A discussion of exchange listing and trading matters associated with an investment in a Fund is contained in the Prospectus under “PURCHASE AND SALE INFORMATION” and “ADDITIONAL PURCHASE AND SALE INFORMATION.” The discussion below supplements, and should be read in conjunction with, such sections of the Prospectus.

The Shares of each Fund are approved for listing and trading on the Exchange, subject to notice of issuance. The Shares trade on the Exchange at prices that may differ to some degree from their net asset value. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of Shares of a Fund will continue to be met.

The Exchange may consider the suspension of trading in, and may initiate delisting proceedings of, the Shares of a Fund under any of the following circumstances: (i) if any of the continued listing requirements set forth in the Exchange rules are not continuously maintained; (ii) if the Exchange files separate proposals under Section 19(b) of the Securities Exchange Act of 1934, as amended, and any of the statements or representations regarding (a) the description of the Index, portfolio, or reference asset; (b) limitations on the Index or the Fund’s portfolio holdings or reference assets; or (c) the applicability of the Exchange listing rules specified in such proposals are not continuously maintained; (iii) if following the initial 12-month period beginning at the commencement of trading of the Fund, there are fewer than 50 record or beneficial owners of the Shares of the Fund; (iv) if the value of the Fund’s underlying index or portfolio of securities on which the Fund is based is no longer calculated or available; or (v) such other event shall occur or condition shall exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. If the Intraday Indicative Value of the fund is not being disseminated as required by Exchange rules, the Exchange may halt trading during the day in which such interruption occurs. If the interruption persists past the trading day in which it occurred, the Exchange will halt trading in the Fund Shares. The Exchange will remove the Shares from listing and trading upon termination of a Fund. The Trust reserves the right to adjust the Fund Share price of a Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of a Fund.

The Trust reserves the right to adjust the Share price of a Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

As in the case of other publicly traded securities, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

The base and trading currencies of the Funds is the U.S. dollar. The base currency is the currency in which a Fund’s net asset value per Share is calculated and the trading currency is the currency in which Shares of a Fund are listed and traded on the Exchange.
