SPDR^® Blackstone Senior Loan ETF

(formerly, SPDR Blackstone / GSO Senior Loan ETF)

Investment Objective

The investment objective of the SPDR Blackstone Senior Loan ETF (the “Fund”) is to provide current income consistent with the preservation of capital.

Fees and Expenses of the Fund

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

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

Management fees	[0.70]%
Distribution and service (12b-1) fees	None
Other expenses	[0.00]%
Acquired fund fees and expenses	[0.01]%
Total annual Fund operating expenses	[0.71]%

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Year 1	Year 3	Year 5	Year 10
$[73]	$[227]	$[395]	$[883]

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was [ ]% of the average value of its portfolio.

The Fund's Principal Investment Strategy

In pursuing its investment objective, the Fund seeks to outperform the Markit iBoxx USD Liquid Leveraged Loan Index (the “Primary Index”) and the S&P/LSTA U.S. Leveraged Loan 100 Index (the “Secondary Index”) by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in Senior Loans. For purposes of this 80% test, “Senior Loans” are first lien senior secured floating rate bank loans. A Senior Loan is an advance or commitment of funds made by one or more banks or similar financial institutions, including the Fund, to one or more corporations, partnerships or other business entities and pays interest at a floating or adjusting rate that is determined periodically at a designated premium above a base lending rate, most commonly the London Interbank Offered Rate (“LIBOR”). A Senior Loan is senior to all unsecured claims against the borrower and senior or equal to all other secured claims, meaning that, in the event of a bankruptcy, the Senior Loan, together with other first lien claims, is entitled to be the first to be repaid out of proceeds of the assets securing the loans, before other existing claims or interests receive repayment. However, in bankruptcy proceedings, there may be other claims, such as taxes or additional advances that take precedence. The Primary Index is composed of the 100 most liquid Senior Loans in the market, while the Secondary Index is composed of the 100 largest Senior Loans in the market, as measured by the

Table of Contents

borrowed amounts outstanding. The Fund intends to hold a large percentage of the components of the Primary and Secondary Indexes. It is anticipated that the Fund will invest approximately 50% to 75% of its net assets in Senior Loans that are eligible for inclusion in the Primary and/or Secondary Indexes. Senior Loans included in the Primary and/or Secondary Indexes, and in which the Fund may invest, may include covenant-lite loans, which may contain fewer or no maintenance covenants compared to other loans. Each of the Fund's Senior Loan investments is expected to have no less than $250 million par outstanding.

The Fund invests in Senior Loans that are made predominantly to businesses operating in North America, but may also invest in Senior Loans made to businesses operating outside of North America. The Fund may invest in Senior Loans directly, either from the borrower as part of a primary issuance or in the secondary market through assignments of portions of Senior Loans from third parties, or participations in Senior Loans, which are contractual relationships with an existing lender in a loan facility whereby the Fund purchases the right to receive principal and interest payments on a loan but the existing lender remains the record holder of the loan. Under normal market conditions, it is expected that the Fund's Senior Loan investments will maintain an average interest rate duration of less than 90 days.

In selecting securities for the Fund, the Fund's sub-adviser, Blackstone Liquid Credit Strategies LLC (formerly, GSO / Blackstone Debt Funds Management LLC) (the “Sub-Adviser”), seeks to construct a portfolio of loans that it believes is less volatile than the general loan market. In addition, when making investments, the Sub-Adviser seeks to maintain appropriate liquidity and price transparency for the Fund. On an on-going basis, the Sub-Adviser adds or removes those individual loans that it believes will cause the Fund to outperform or underperform, respectively, the Primary and Secondary Indexes. The Fund's strategy may result in a high portfolio turnover rate.

When identifying prospective investment opportunities in Senior Loans, the Sub-Adviser currently intends to invest principally in Senior Loans that are below investment-grade quality and will rely on fundamental credit analysis in an effort to attempt to minimize the loss of the Fund's capital. While credit ratings assigned by Moody's Investors Service, Inc., Standard & Poor's Financial Services, LLC and/or Fitch Inc. (the “SROs” (statistical rating agencies)) will be considered, such ratings will not be determinative in the Sub-Adviser's process in the selection of specific debt securities (including Senior Loans). The Senior Loans and other securities that the Sub-Adviser is likely to select for investment in by the Fund will typically be rated below investment-grade quality by one or more of the SROs or, if unrated, will typically, in the opinion of the Sub-Adviser, be of similar credit quality. If circumstances cause the Sub-Adviser to take a negative credit view on an existing investment the Fund may, if the Sub-Adviser believes that circumstances require, exit the investment. The circumstances giving rise to the Sub-Adviser's negative credit view may, but will not necessarily, coincide with a downgrade of the Senior Loan or other security's credit rating. The Sub-Adviser expects to invest in Senior Loans, other loans and bonds of companies, including high yield securities (commonly known as “junk”) and Rule 144A securities, possessing the following attributes, which it believes will help generate higher risk adjusted total returns:

Leading, defensible market positions. The Sub-Adviser intends to invest in companies that it believes have developed strong positions within their respective markets and exhibit the potential to maintain sufficient cash flows and profitability to service their obligations in a range of economic environments. The Sub-Adviser will seek companies that it believes possess advantages in scale, scope, customer loyalty, product pricing, or product quality versus their competitors, thereby minimizing business risk and protecting profitability.

Investing in companies with positive cash flow. The Sub-Adviser intends to invest primarily in established companies which have demonstrated a record of profitability and cash flows over several economic cycles. The Sub-Adviser believes such companies are well-positioned to maintain consistent cash flow to service and repay their obligations and maintain growth in their businesses or market share. The Sub-Adviser does not intend to invest in primarily start-up companies, companies in turnaround situations or companies with speculative business plans.

Proven management teams. The Sub-Adviser intends to focus on investments in which the target company has an experienced management team with an established track record of success. The Sub-Adviser will typically require companies to have in place proper incentives to align management's goals with the Fund's goals.

Private equity sponsorship. Often the Sub-Adviser will seek to participate in transactions sponsored by what it believes to be high-quality private equity firms. The Sub-Adviser believes that a private equity sponsor's willingness to invest significant sums of equity capital into a company is an implicit endorsement of the quality of the investment. Further, private equity sponsors of companies with significant investments at risk have the ability and a strong incentive to contribute additional capital in difficult economic times should operational issues arise.

Table of Contents

Diversification, concentration and reliance on other lenders. The Sub-Adviser will seek to invest broadly among companies and industries, thereby potentially reducing the risk of a downturn in any one company or industry having a disproportionate impact on the value of the Fund's portfolio. While the Fund does not treat banks originating loans as the issuers of such loans, it is possible that under a different interpretation the Fund may be deemed to concentrate its investments in the financial services industries. Loans, and the collateral securing them, are typically monitored by agents for the lenders, which may be the originating bank or banks. The Fund may be affected by the creditworthiness of the agent bank and other intermediate participants in a Senior Loan, in addition to the borrower, since rights that may exist under the loan against the borrower if the borrower defaults are typically asserted by or through the agent bank or intermediate participant. Agents are typically large commercial banks, although for Senior Loans that are not broadly syndicated they can also include thrift institutions, insurance companies or finance companies (or their affiliates). Such companies may be especially susceptible to the effects of changes in interest rates resulting from changes in U.S. or foreign fiscal or monetary policies, governmental regulations affecting capital raising activities or other economic or market fluctuations.

Principal Risks of Investing in the Fund

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

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

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

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

Table of Contents

liquidate such loans in a compressed period of time. Some of the loans in which the Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. The Fund may experience delays in enforcing its rights on its holdings of covenant-lite loans.

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

Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Cash Transaction Risk: The Fund may sell portfolio securities to meet some or all of a redemption request with cash. In such cases, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Financial Sector Risk: Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

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

LIBOR Risk: On July 27, 2017, the United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced that after 2021, it will cease its active encouragement of banks to provide quotations needed to sustain the LIBOR rate. On March 5, 2021, the administrator of LIBOR announced a delay in the phase out of the majority of the USD LIBOR publications until June 30, 2023, with the remainder of LIBOR publications to still end on December 31, 2021. There remains uncertainty regarding the future of LIBOR and the nature of any replacement rate. The replacement and/or discontinuation of LIBOR could lead to significant short-term and long-term uncertainty and market instability. The unavailability and/or discontinuation of LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments that reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments may have such provisions and there is uncertainty regarding the effectiveness of any alternative methodology. In addition, the unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades.

Table of Contents

Liquidity Risk: There is no organized exchange on which loans are traded and reliable market quotations may not be readily available. A majority of the Fund's assets are likely to be invested in loans that are less liquid than securities traded on national exchanges. Illiquidity of the Fund's holdings may limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. Loans with reduced liquidity involve greater risk than securities with more liquid markets. Available market quotations for such loans may vary over time, and if the credit quality of a loan unexpectedly declines, secondary trading of that loan may decline for a period of time. During periods of infrequent trading, valuing a loan can be more difficult and buying and selling a loan at an acceptable price can be more difficult and delayed. In the event that the Fund voluntarily or involuntarily liquidates portfolio assets during periods of infrequent trading, it may not receive full value for those assets. Therefore, elements of judgment may play a greater role in valuation of loans. To the extent that a secondary market exists for certain loans, the market may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

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

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

Non-U.S. Securities Risk: Non-U.S. securities are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

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

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

Table of Contents

quotations are not readily available. The value established for any portfolio holding at a point in time might differ from what would be produced using a different methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their valuations from one day to the next than if market quotations were used. In addition, there is no assurance that the Fund could sell or close out a portfolio position for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio position is sold or closed out at a discount to the valuation established by the Fund at that time.

Portfolio Management

Investment Adviser and Sub-Adviser

SSGA Funds Management, Inc. (“SSGA FM” or the “Adviser”) serves as the investment adviser to the Fund. Blackstone Liquid Credit Strategies LLC serves as investment sub-adviser to the Fund, subject to supervision by the Adviser and oversight by the SSGA Active Trust's Board of Trustees. To the extent that a reference in this Prospectus refers to the Adviser, with respect to the Fund, such reference should also be read to refer to Blackstone Liquid Credit Strategies LLC, where the context requires.

Portfolio Managers

The professionals at the Sub-Adviser primarily responsible for the day-to-day management of the Fund are Daniel T. McMullen and Gordon McKemie.

Daniel T. McMullen is a Senior Managing Director of the Sub-Adviser and lead Portfolio Manager of the Fund. He joined Blackstone Liquid Credit Strategies LLC in 2002.

Gordon McKemie is a Principal of the Sub-Adviser and Portfolio Manager of the Fund. He joined Blackstone Liquid Credit Strategies LLC in 2012.

Purchase and Sale Information

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

costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund Shares (bid) and the lowest price a seller is willing to accept for Fund Shares (ask) (the “bid-ask spread”). Recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at https://www.ssga.com/spdrs.

Tax Information

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

Payments to Broker-Dealers and Other Financial Intermediaries

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

The Fund's Principal Investment Strategy

SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) invests, under normal circumstances, at least 80% of the Fund's net assets (plus the amount of borrowings for investment purposes) in a diversified portfolio of U.S. dollar-denominated investment-grade fixed income securities. Investment-grade fixed income securities are instruments that are rated at the time of purchase BBB- or higher by Standard & Poor's Financial Services LLC and/or Fitch Inc., or Baa3 or higher by Moody's Investors Service, Inc., or, if unrated, determined by the management team to be of equivalent quality. The Fund invests in fixed and floating rate securities of varying maturities, such as corporate obligations (including bonds, commercial paper of U.S. and foreign entities, master notes, and medium term notes); government bonds (including U.S. Treasury Bills, notes, and bonds); agency securities; privately-issued securities; asset-backed and mortgage-backed securities; money market instruments (including U.S. and foreign bank time deposits, certificates of deposit, and banker acceptances) and other investment companies. The Fund may invest up to 10% of the Fund's net assets in high yield securities (commonly known as “junk bonds”). The Fund may also invest in exchange traded products (“ETPs”). ETPs include exchange traded funds registered under the Investment Company Act of 1940, as amended (the “1940 Act”) (“Underlying ETFs”) and exchange traded notes (“ETNs”). In addition, the Fund may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services.

Under normal circumstances, the effective duration of the Fund is expected to be one year or less. Effective duration is a measure of the Fund's price sensitivity to changes in yields or interest rates; however, investors should be aware that effective duration is not an exact measurement and may not reliably predict a particular security's price sensitivity to

Table of Contents

changes in yield or interest rates. In addition, under normal circumstances the Fund expects to maintain a weighted average maturity that is two and a half years or less. Weighted average maturity is a U.S. dollar-weighted average of the remaining term to maturity of the underlying securities in the Fund. For the purposes of determining the Fund's weighted average maturity, a security's final maturity date, or for amortizing securities such as asset-backed and mortgage-backed securities, its weighted average life will be used for calculation purposes. The Adviser buys and sells securities for the Fund based on its analysis of credit quality and overall portfolio duration. The Adviser may also use derivative instruments (primarily futures contracts, interest rate and credit default swaps, and options on treasury futures) to manage yield, interest rate exposure (also known as duration), weighted average maturity, and exposure to credit quality. As of July 31, 2021, a significant portion of the Fund comprised securities of companies in the [financial and industrial sectors], although this may change from time to time. The Fund is not a money market fund and does not seek to maintain a stable net asset value of $1.00 per share.

Principal Risks of Investing in the Fund

Exchange Traded Products Risk: The Fund is subject to substantially the same risks as those associated with the direct ownership of the securities represented by the ETPs in which it invests. In addition, the shares of certain ETPs may trade at a premium or discount to their intrinsic value (i.e., the market value may differ from the net asset value of an ETF's shares) for a number of reasons. For example, supply and demand for shares of an Underlying ETF or market disruptions may cause the market price of the Underlying ETF to deviate from the value of the Underlying ETF's investments, which may be exacerbated in less liquid markets. The value of an ETN may also differ from the valuation of its reference market due to changes in the issuer's credit rating. By investing in ETPs, the Fund indirectly bears the Fund's proportionate share of any fees and expenses (e.g. management, custody, accounting, and administration) of the ETP, if applicable, in addition to the fees and expenses that the Fund and its shareholders directly bear in connection with the Fund's own operations.

Affiliated ETP Risk: The Adviser may receive management or other fees from the ETPs (“Affiliated ETPs”) in which the Fund may invest, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the

Table of Contents

effect on an Affiliated ETP in which the 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 Fund.

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

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

Industrial Sector Risk: Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil

Table of Contents

liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

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

Low Short-Term Interest Rates Risk: During market conditions in which short-term interest rates are at low levels, the Fund's yield can be very low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). During these conditions, it is possible that the Fund will generate an insufficient amount of income to pay its expenses, and will not be able to pay its scheduled dividend.

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

Money Market Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds.

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

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

underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Certain countries have recently experienced (or currently are expected to experience) negative interest rates on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify the Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

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

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

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

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

Variable and Floating Rate Securities Risk: During periods of increasing interest rates, changes in the coupon rates of variable or floating rate securities may lag behind the changes in market rates or may have limits on the maximum increases in coupon rates. Alternatively, during periods of declining interest rates, the coupon rates on

such securities will typically readjust downward resulting in a lower yield. Floating rate notes are generally subject to legal or contractual restrictions on resale, may trade infrequently, and their value may be impaired when the Fund needs to liquidate such securities.

Purchase and Sale Information

Individual Fund Shares may only be purchased and sold on the NYSE Arca, Inc., other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at net asset value (“NAV”), Fund Shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling Fund Shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund Shares (bid) and the lowest price a seller is willing to accept for Fund Shares (ask) (the “bid-ask spread”). Recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at https://www.ssga.com/spdrs.

Additional Strategies Information

Principal Strategies

Please see each Fund's respective “The Fund's Principal Investment Strategy” section under “Fund Summaries” above for a complete discussion of its principal investment strategies. The Funds may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Funds and therefore are not described in this Prospectus. These securities, techniques and practices, together with their risks, are described in the Statement of Additional Information (the “SAI”) which you may obtain free of charge by contacting shareholder services (see the back cover of this Prospectus for the address and phone number).

The Board of Trustees of SSGA Active Trust (the “Board”) may change each Fund's investment objective, investment strategy and other policies without shareholder approval, except as otherwise noted in this Prospectus or in the SAI.

Non-Principal Strategies

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

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

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

Lending of Securities. Each Fund may lend its portfolio securities in an amount not to exceed 40% of the value of its net assets via a securities lending program through its securities lending agent, State Street Bank and Trust Company (“State Street” or the “Lending Agent”), to brokers, dealers and other financial institutions desiring to borrow securities to complete transactions and for other purposes. A securities lending program allows a Fund to receive a portion of the income generated by lending its securities and investing the respective collateral. A Fund will receive collateral for each loaned security which is at least equal to the market value of that security, marked to market each trading day. In the securities lending program, the borrower generally has the right to vote the loaned securities; however, a Fund may call loans to vote proxies if a material issue affecting the Fund's economic interest in the investment is to be voted upon. Security loans may be terminated at any time by a Fund.

Affiliated ETP Risk. The Adviser may receive management or other fees from Affiliated ETPs, as well as a management fee for managing the Fund. It is possible that a conflict of interest among the Fund and the Affiliated ETPs could affect how the Adviser fulfills its fiduciary duties to the Fund and the Affiliated ETPs. Because the amount of the investment management fees to be retained by the Adviser may differ depending upon the Affiliated ETPs in which the Fund invests, there is a conflict of interest for the Adviser in selecting the Affiliated ETPs. In addition, the Adviser may have an incentive to take into account the effect on an Affiliated ETP in which the 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 Fund.

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

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

Cash Transaction Risk. To the extent a Fund sells portfolio securities to meet some or all of a redemption request with cash, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, a Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Table of Contents

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

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

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

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

Debt Securities Risk. The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of a Fund's fixed income securities to decrease, a decline in a Fund's income and yield, an adverse impact on the liquidity of a Fund's fixed income securities, and increased volatility of the fixed income markets. The current historically low interest rate environment heightens the risks associated with rising interest rates. During periods when interest rates are at low levels, a Fund's yield can be low, and a Fund may have a negative yield (i.e., it may lose money on an operating basis). If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations

Table of Contents

paying interest at lower rates. During periods of falling interest rates, the income received by a Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities.

Derivatives Risk. A derivative is a financial contract the value of which depends on, or is derived from, the value of an underlying asset, interest rate, or index. Derivative transactions typically involve leverage and may have significant volatility. It is possible that a derivative transaction will result in a loss greater than the principal amount invested, and a Fund may not be able to close out a derivative transaction at a favorable time or price. Risks associated with derivative instruments include potential changes in value in response to interest rate changes or other market developments or as a result of the counterparty's credit quality; the potential for the derivative transaction not to have the effect the Adviser anticipated or a different or less favorable effect than the Adviser anticipated; the failure of the counterparty to the derivative transaction to perform its obligations under the transaction or to settle a trade; possible mispricing or improper valuation of the derivative instrument; imperfect correlation in the value of a derivative with the asset, rate, or index underlying the derivative; the risk that a Fund may be required to post collateral or margin with its counterparty, and will not be able to recover the collateral or margin in the event of the counterparty's insolvency or bankruptcy; the risk that a Fund will experience losses on its derivatives investments and on its other portfolio investments, even when the derivatives investments may be intended in part or entirely to hedge those portfolio investments; the risks specific to the asset underlying the derivative instrument; lack of liquidity for the derivative instrument, including without limitation absence of a secondary trading market; the potential for reduced returns to a Fund due to losses on the transaction and an increase in volatility; the potential for the derivative transaction to have the effect of accelerating the recognition of gain; and legal risks arising from the documentation relating to the derivative transaction.

Futures Contract Risk; Other Exchange-Traded Derivatives Risk. The risk of loss relating to the use of futures contracts and other exchange-traded derivatives is potentially unlimited. The ability to establish and close out positions in futures contracts and other exchange-traded derivatives will be subject to the development and maintenance of a liquid secondary market. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract or other exchange-traded derivative or at any particular time. In the event no such market exists for a particular derivative, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. In using futures contracts and other exchange-traded derivatives, the Fund will be reliant on the ability of the Adviser to predict market and price movements correctly; the skills needed to use such derivatives successfully are different from those needed for traditional portfolio management. If the Fund uses futures contracts or other exchange-traded derivatives for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures and other exchange-traded derivatives, for a number of reasons, may not correlate perfectly with movements in the securities or index underlying them. For example, participants in the futures markets and in markets for other exchange-traded derivatives are subject to margin deposit requirements. Such requirements may cause investors to take actions with respect to their derivatives positions that they would not otherwise take. The margin requirements in the derivatives markets may be less onerous than margin requirements in the securities markets in general, and as a result those markets may attract more speculators than the securities markets do. Increased participation by speculators in those markets may cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of general market trends by the Adviser still may not result in a successful derivatives activity over a very short time period. The risk of a position in a futures contract or other exchange-traded derivative may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Fund will incur brokerage fees in connection with its exchange-traded derivatives transactions. The Fund will typically be required to post margin with its futures commission merchant in connection with its transactions in futures contracts and other exchange-traded derivatives. In the event of an insolvency of the futures commission merchant or a clearing house, the Fund may not be able to recover all (or any) of the margin it has posted with the futures commission merchant, or to realize the value of any increase in the price of its positions, or it may experience a significant delay in doing so. The Fund also may be delayed or prevented from recovering margin or other amounts deposited with a futures commission merchant or futures clearinghouse. The Commodity Futures Trading Commission (the “CFTC”) and the various exchanges have established limits referred to as “speculative

Table of Contents

position limits” on the maximum net long or net short positions that any person and certain affiliated entities may hold or control in a particular futures contract. Trading limits are imposed on the number of contracts that any person may trade on a particular trading day. An exchange may order the liquidation of positions found to be in violation of these limits and it may impose sanctions or restrictions. In addition, the Dodd-Frank Act requires the CFTC to establish speculative position limits on certain commodity futures contracts and their economically equivalent futures, options and swaps. Regulatory action taken by the CFTC to establish these additional position limits may adversely affect the market liquidity of the futures, options and economically equivalent derivatives in which the Fund may invest. It is possible that, as a result of such limits, the Fund's Adviser will be precluded from taking positions in certain futures contracts or over-the-counter derivatives as a result of positions held by other clients of the Adviser or by the Adviser or its affiliates themselves.

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

Options Risk. The successful use of the Fund's options strategies depends on the ability of the Adviser to forecast market movements correctly. For example, if the Fund were to write a call option on a security based on the Adviser's expectation that the price of the security would fall, but the price were to rise instead, the Fund could be required to sell the security upon exercise at a price below the current market price. Similarly, if the Fund were to write a put option based on the Adviser's expectation that the price of the underlying security would rise, but the price were to fall instead, the Fund could be required to purchase the security upon exercise at a price higher than the current market price. When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option's expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying security, since the Fund will not realize a loss if the security's price does not change over a relatively short time period. The effective use of options also depends on the Fund's ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price. The sale of options by the Fund may create investment leverage.

Swaps Risk. A swap is a two-party contract that generally obligates one party to pay the positive return and the other party to pay the negative return on a specified reference security, basket of securities, security index or index component. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and are subject to counterparty risk (e.g., the risk of a counterparty's defaulting on the obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps may also be considered illiquid. It may not be possible for a Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Exchange Traded Funds Risk. As a shareholder of another investment company, a Fund relies on that investment company to achieve its investment objective. If the investment company fails to achieve its objective, the value of a Fund's investment could decline, which could adversely affect the Fund's performance. In addition, a Fund is subject to substantially the same risks as those associated with the direct ownership of the securities or other assets represented by an underlying ETF in which it invests. By investing in another investment company, a Fund indirectly bears its proportionate share of any fees and expenses of the other investment company, if applicable, in addition to the fees and expenses that such Fund and its shareholders directly bear in connection with the Fund's operations. A Fund may invest in ETFs that are not registered or regulated under the 1940 Act. These instruments typically hold commodities, such as gold or oil, currency or other property that is itself not a security (see also “Investments in Exchange Traded Commodity Trusts” below). Federal securities laws impose limitations on a Fund's ability to invest in other investment companies.

Table of Contents

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

Exchange Traded Products Risk. A Fund is subject to substantially the same risks as those associated with the direct ownership of the securities or other assets represented by the ETPs in which a Fund invests. The shares of certain ETPs may trade at a premium or discount to their net asset values. For example, supply and demand for shares of an underlying ETF or market disruptions may cause the market price of the underlying ETF to deviate from the value of the underlying ETF's investments, which may be exacerbated in less liquid markets. By investing in ETPs, a Fund bears the proportionate share of any fees and expenses (e.g. management, custody, accounting, and administration) of the ETP, if applicable, in addition to the fees and expenses that a Fund and its shareholders directly bear in connection with the Fund's operations.

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

Financial Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

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

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

Industrial Sector Risk. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities will likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, a component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs.

Interest Rate Risk. Interest rate risk is the risk that the securities held by a Fund will decline in value because of increases in market interest rates. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. Debt securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than debt securities with shorter durations. For example, the value of a security with a duration of five years would be expected to decrease by 5% for every 1% increase in interest rates. Falling interest rates also create the potential for a decline in a Fund's income and yield. Interest-only and principal-only securities are especially sensitive to interest rate changes, which can affect not only their prices but can also change the income flows and repayment assumptions about those investments. Variable and floating rate securities also generally increase or decrease in value in response to changes in interest rates, although generally to a lesser degree than fixed-rate securities. A substantial increase in interest rates may also have an adverse impact on the liquidity of a security, especially those with longer durations. Interest rate changes can be sudden and unpredictable, and are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply and demand for bonds. Changes in government or central bank policy, including changes in tax policy or changes in a central bank's implementation of specific policy goals, may have a substantial impact on interest rates. This could lead to heightened levels of interest rate, volatility and liquidity risks for the fixed income markets generally and could have a substantial and immediate effect on the values of a Fund's investments. There can be no guarantee that any particular government or central bank policy will be continued, discontinued or changed, nor that any such policy will have the desired effect on interest rates.

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

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

Table of Contents

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

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

LIBOR Risk. On July 27, 2017, the United Kingdom's Financial Conduct Authority, which regulates LIBOR, announced that after 2021, it will cease its active encouragement of banks to provide quotations needed to sustain the LIBOR rate. On March 5, 2021, the administrator of LIBOR announced a delay in the phase out of the majority of the USD LIBOR publications until June 30, 2023, with the remainder of LIBOR publications to still end on December 31, 2021. There remains uncertainty regarding the future of LIBOR and whether it will continue to exist in its current, or a modified, form. There is also uncertainty surrounding the nature of any replacement rate. Certain alternatives to LIBOR have been established or are in development in most major currencies, including the Secured Overnight Financing Rate (SOFR), which is intended to replace the U.S. Dollar LIBOR. The replacement and/or discontinuation of LIBOR could lead to significant short-term and long-term uncertainty and market instability. The unavailability and/or discontinuation of LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments that reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments may have such provisions and there is uncertainty regarding the effectiveness of any alternative methodology. Abandonment of or modifications to LIBOR could lead to significant short-term and long-term uncertainty and market instability. In addition, the unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to a Fund's investments resulting from a substitute reference rate may also adversely affect the Fund's performance and/or NAV.

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

Low Short-Term Interest Rates Risk. During market conditions in which short-term interest rates are at low levels, a Fund's yield can be very low, and a Fund may have a negative yield (i.e., it may lose money on an operating basis). During these conditions, it is possible that a Fund will generate an insufficient amount of income to pay its expenses, and will not be able to pay its scheduled dividend.

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

Market Risk. Market prices of investments held by a Fund will go up or down, sometimes rapidly or unpredictably. A Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest

Table of Contents

rates, changes in actual or perceived creditworthiness of issuers and general market liquidity. Even if general economic conditions do not change, the value of an investment in a Fund could decline if the particular industries, sectors or companies in which the Fund invests do not perform well or are adversely affected by events. Further, legal, political, regulatory and tax changes also may cause fluctuations in markets and securities prices. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on a Fund and its investments.

An outbreak of a respiratory disease caused by a novel coronavirus (known as COVID-19) first detected in China in December 2019 has resulted in a global pandemic and major disruptions to economies and markets around the world, including the United States. Financial markets experienced and may continue to experience extreme volatility and severe losses, and trading in many instruments was and may continue to be disrupted as a result. Liquidity for many instruments was and may continue to be greatly reduced for periods of time. Some interest rates are very low and in some cases yields are negative. Governments and central banks, including the Federal Reserve in the United States, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. The impact of these measures, and whether they will be effective to mitigate the economic and market disruption, will not be known for some time. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to a Fund by its service providers.

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

Mortgage-Related and Other Asset-Backed Securities Risk. Investments in mortgage-related and other asset-backed securities are subject to the risk of significant credit downgrades, illiquidity, and defaults to a greater extent than many other types of fixed income investments. The liquidity of mortgage-related and asset-backed securities may change over time. Mortgage-related securities represent a participation in, or are secured by, mortgage loans. Other asset-backed securities are typically structured like mortgage-related securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include, for example, items such as motor vehicle installment sales or installment loan contracts, leases on various types of real and personal property, and receivables from credit card agreements. During periods of falling interest rates, mortgage-related and other asset-backed securities, which typically provide the issuer with the right to prepay the security prior to maturity, may be prepaid, which may result in a Fund having to reinvest the proceeds in other investments at lower interest rates. During periods of rising interest rates, the average life of mortgage-related and other asset-backed securities may extend because of slower-than expected principal payments. This may lock in a below market interest rate, increase the security's duration and interest rate sensitivity, and reduce the value of the security. As a result, mortgage-related and other asset-backed securities may have less potential for capital appreciation during periods of declining interest rates than other debt securities of comparable maturities, although they may have a similar risk of decline in market values during periods of rising interest rates. Prepayment rates are difficult to predict and the potential impact of prepayments on the value of a mortgage-related or other asset-backed security depends on the terms of the instrument and can result in significant volatility. The price of a mortgage-related or other asset-backed security also depends on the credit quality and adequacy of the underlying assets or collateral. Defaults on the underlying assets, if any, may impair the value of a

Table of Contents

mortgage-related or other asset-backed security. For some asset-backed securities in which a Fund invests, such as those backed by credit card receivables, the underlying cash flows may not be supported by a security interest in a related asset. Moreover, the values of mortgage-related and other asset-backed securities may be substantially dependent on the servicing of the underlying asset pools, and are therefore subject to risks associated with the negligence or malfeasance by their servicers and to the credit risk of their servicers. In certain situations, the mishandling of related documentation may also affect the rights of securities holders in and to the underlying collateral. There may be legal and practical limitations on the enforceability of any security interest granted with respect to underlying assets, or the value of the underlying assets, if any, may be insufficient if the issuer defaults.

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

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

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

Non-U.S. Securities Risk. Investments in securities of non-U.S. issuers (including depositary receipts) entail risks not typically associated with investing in securities of U.S. issuers. Similar risks may apply to securities traded on a U.S. securities exchange that are issued by entities with significant exposure to non-U.S. countries. In certain countries, legal remedies available to investors may be more limited than those available with regard to U.S. investments. Because non-U.S. securities are typically denominated and traded in currencies other than the U.S. dollar, the value of the Fund's assets, to the extent they are non-U.S. dollar denominated, may be affected favorably or unfavorably by currency exchange rates, exchange control regulations, and restrictions or prohibitions on the repatriation of non-U.S. currencies. To the extent underlying securities held by a Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Income and gains with respect to investments in certain countries may be subject to withholding and other taxes. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the United States. The securities of some non-U.S. entities are less liquid and at times more volatile than securities of comparable U.S. entities, and could become subject to sanctions or embargoes that adversely affect a Fund's investment. Non-U.S. transaction costs, such as brokerage commissions and custody costs may be higher than in the U.S. In addition, there may be a possibility of nationalization or expropriation of assets, imposition of currency exchange controls, confiscatory taxation, and diplomatic developments that could adversely affect the values of a Fund's investments in certain non-U.S. countries. Investments in securities of non-U.S. issuers also are subject to foreign political and economic risk not associated with U.S. investments, meaning that political events (civil unrest, national elections, changes in political conditions and foreign relations, imposition of exchange controls and repatriation restrictions), social and economic events (labor strikes, rising inflation) and natural disasters occurring in a country where a Fund invests could cause the Fund's investments in that country to experience gains or losses. Certain countries have recently experienced (or currently are expected to experience) negative interest rates

Table of Contents

on certain fixed-income securities, and similar interest rate conditions may be experienced in other regions. Investments in fixed-income securities with very low or negative interest rates may magnify a Fund's susceptibility to interest rate risk and diminish yield and performance, and such investments may be subject to heightened volatility and reduced liquidity.

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

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

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

Risks of Loan Assignments and Participations. A Fund, as the purchaser of an assignment, typically succeeds to all the rights and obligations of the assigning institution and becomes a lender under the credit agreement with respect to the debt obligation. However, a Fund may not be able to unilaterally enforce all rights and remedies under the loan and with regard to any associated collateral. Because assignments may be arranged through private negotiations between potential assignees and potential assignors, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning lender. In addition, if the loan is foreclosed, the Fund could become a partial owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral. A Fund may be required to pass along to a purchaser that buys a loan from the Fund by way of assignment, a portion of any fees to which the Fund is entitled under the loan. When purchasing participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the loan in which it has purchased the participation. As a result, the Fund will be subject to the credit risk of both the borrower and the lender that is selling the participation. In the event of the insolvency of the lender selling a participation, the Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower.

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

Table of Contents

invalidation of Senior Loans or causing interest previously paid to be refunded to the borrower. Senior Loans are also subject to high yield securities risks and liquidity risks described above. In addition, bank loans may be subject to extended settlement periods, which may impair the Fund's ability to sell or realize the full value of its loans in the event of a need to liquidate such loans in a compressed period of time. Some of the loans in which a Fund may invest or obtain exposure to may be “covenant-lite” loans. Covenant-lite loans may contain fewer or no maintenance covenants compared to other loans and may not include terms which allow the lender to monitor the performance of the borrower and declare a default if certain criteria are breached. A Fund may experience relatively greater realized or unrealized losses or delays in enforcing its rights on its holdings of covenant-lite loans than its holdings of loans with the usual covenants.

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

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

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

U.S. Treasury Obligations Risk. U.S. Treasury obligations may differ from other fixed income securities in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of a Fund‘s U.S. Treasury obligations to decline. The total public debt of the United States as a percentage of gross domestic product has grown rapidly since the beginning of the recent financial downturn. Although high debt levels do not necessarily indicate or cause economic

Table of Contents

problems, they may create certain systemic risks if sound debt management practices are not implemented. A high national debt level may increase market pressures to meet government funding needs, which may drive debt cost higher and cause a country to sell additional debt, thereby increasing refinancing risk. A high national debt also raises concerns that a government will not be able to make principal or interest payments when they are due. In the worst case, unsustainable debt levels can cause a decline in the value of the dollar (which may lead to inflation), and can prevent the U.S. government from implementing effective counter-cyclical fiscal policy in economic downturns. U.S. Treasury securities are currently given the top rating by all major ratings agencies except Standard & Poor's Ratings Services, which rates them AA+, one grade below their top rating. Since downgrading U.S. Treasury securities from AAA to AA+ in 2011, Standard & Poor's Ratings Services has affirmed its rating. A downgrade of the ratings of U.S. government debt obligations, such as U.S. Treasury obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade below AA+ rating by Standard & Poor's Ratings Services may cause the value of a Fund's U.S. Treasury obligations to decline.

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

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

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

Non-Principal Risks

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

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. A Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”), which are responsible for the creation and redemption activity for a Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to

Table of Contents

NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Conflicts of Interest Risk. An investment in a Fund may be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to a Fund, such as securities lending agency services, custodial, administrative, bookkeeping, and accounting services, transfer agency and shareholder servicing, securities brokerage services, and other services for which the Fund would compensate the Adviser and/or such affiliates. 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, provided that the Adviser will comply with applicable regulatory requirements.

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

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

Costs of Buying and Selling Shares. Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for Fund Shares (the “bid” price) and the price at which an investor is willing to sell Fund Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for Fund Shares based on trading volume and market liquidity, and is generally lower if Fund Shares have more trading volume and market liquidity and higher if Fund Shares have little trading volume and market liquidity. Further, increased market volatility may cause increased bid/ask spreads. Due to the costs of buying or selling Fund Shares, including bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

Cybersecurity Risk. With the increased use of technologies such as the Internet and the dependence on computer systems to perform business and operational functions, funds (such as the Funds) and their service providers (including the Adviser) may be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions. In general, cyber-attacks are deliberate, but unintentional events may have similar effects. Cyber-attacks include, among others, stealing or corrupting data maintained online or digitally, preventing legitimate users from accessing information or services on a website, releasing confidential information without authorization, and causing operational disruption. Successful cyber-attacks against, or security breakdowns of, a Fund, the Adviser, a sub-adviser or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect a Fund or its shareholders. For instance, cyber-attacks or technical malfunctions may interfere with the processing of shareholder or other transactions, affect a Fund's ability to calculate its NAV, cause the release of private shareholder

Table of Contents

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

Limitations on Transactions with Affiliates Risk (SPDR Blackstone Senior Loan ETF only). The 1940 Act limits the Fund's ability to enter into certain transactions with certain of its affiliates, including affiliates of the Sub-Adviser. As a result of these restrictions, the Fund may be prohibited from buying or selling any security directly from or to any portfolio company of one or more private equity funds managed by The Blackstone Group Inc., the Sub-Adviser or any of their respective affiliates. However, the Fund may under certain circumstances purchase any such portfolio company's loans or securities in the secondary market, which could create a conflict for the Sub-Adviser between the interests of the Fund and the portfolio company, in that the ability of the Sub-Adviser to recommend actions in the best interest of the Fund might be impaired. The 1940 Act also prohibits certain “joint” transactions with certain of the Sub-Adviser's affiliates, which could include investments in the same portfolio company (whether at the same or different times). These limitations may limit the scope of investment opportunities that would otherwise be available to the Fund.

Potential Conflicts of Interest Risk (SPDR Blackstone Senior Loan ETF only). The Sub-Adviser will be subject to certain conflicts of interest in its management of the Fund. In the ordinary course of their business activities, the Sub-Adviser and its affiliates may engage in activities where the interests of certain divisions of the Sub-Adviser and its affiliates or the interests of their clients may conflict with the interests of the Funds or its shareholders. As part of its regular business, the Sub-Adviser or its affiliates provide a broad range of investment management, advisory, and other services. Because of such relationships, there may be certain investments that the Sub-Adviser will decline or be unable to make. In addition, employees of such affiliates may possess information relating to such issuers that is not known to the individuals at the Sub-Adviser. Those employees of the Sub-Adviser's affiliates will not be obligated to

Table of Contents

share any such information with the Sub-Adviser and may be prohibited by law or contract from doing so. The Sub-Adviser or certain of its affiliates may come into possession of material non-public information with respect to an issuer. Should this occur, the Sub-Adviser would be restricted from buying or selling securities or loans of the issuer on behalf of the Fund until such time as the information became public or was no longer deemed material, so as to preclude the Fund from participating in an investment.

Securities Lending Risk. Each Fund may lend portfolio securities in an amount not to exceed 40% of the value of its net assets. For these purposes, net assets shall exclude the value of all assets received as collateral for the loan. Such loans may be terminated at any time. Any such loans must be continuously secured by collateral maintained on a current basis in an amount at least equal to the market value of the securities loaned by a Fund, marked to market each trading day. In a loan transaction, as compensation for lending its securities, a Fund will receive a portion of the dividends or interest accrued on the securities held as collateral or, in the case of cash collateral, a portion of the income from the investment of such cash. In addition, a Fund will receive the amount of all dividends, interest and other distributions on the loaned securities. However, the borrower has the right to vote the loaned securities. A Fund will call loans to vote proxies if a material issue affecting the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities, and may involve expenses to a Fund. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. Should the borrower of the securities fail financially, a Fund may experience delays in recovering the securities or exercising its rights in the collateral. Loans are made only to borrowers that are deemed by the securities lending agent to be of good financial standing. In a loan transaction, a Fund will also bear the risk of any decline in value of securities provided as collateral or acquired with cash collateral. Each Fund will attempt to minimize this risk by limiting the investment of cash collateral to high quality instruments of short maturity either directly on behalf of the lending Fund or through one or more joint accounts or funds, which may include those managed by the Adviser. In addition, a Fund will be subject to the risk that any income generated by lending its securities or reinvesting cash collateral is lower than any fees the Fund has agreed to pay a borrower. The Adviser will take into account the tax impact to shareholders of substitute payments for dividends when overseeing a Fund's securities lending activity.

Trading Issues. Although Fund Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for such Fund Shares will develop or be maintained. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to Exchange “circuit breaker” rules. Similar to the shares of operating companies listed on a stock exchange, Fund Shares may be sold short and are therefore subject to the risk of increased volatility in the trading price of the Fund's shares. While each Fund expects that the ability of Authorized Participants to create and redeem Fund Shares at net asset value should be effective in reducing any such volatility, there is no guarantee that it will eliminate the volatility associated with such short sales. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of a Fund will continue to be met or will remain unchanged or that Fund Shares will trade with any volume, or at all, on any stock exchange.

Management

Investment Adviser

SSGA FM serves as the investment adviser to each Fund and, subject to the oversight of the Board, is responsible for the investment management of each Fund. The Adviser provides an investment management program for each Fund and manages the investment of each Fund's assets. The Adviser is a wholly-owned subsidiary of State Street Global Advisors, Inc., which itself is a wholly-owned subsidiary of State Street Corporation. The Adviser is registered with the SEC under the Investment Advisers Act of 1940, as amended. The Adviser and certain other affiliates of State Street Corporation make up SSGA. SSGA is one of the world's largest institutional money managers and the investment management arm of State Street Corporation.

The Adviser's principal business address is One Iron Street, Boston, Massachusetts 02210.

Table of Contents

For the services provided to each Fund under the Investment Advisory Agreement, for the fiscal year ended June 30, 2021, each Fund paid the Adviser the annual fees based on a percentage of each Fund's average daily net assets as set forth below. With respect to each Fund, the management fee is reduced by any acquired fund fees and expenses attributable to the Funds' investments in other investment companies.

SPDR Blackstone Senior Loan ETF	[0.70]%
SPDR SSGA Ultra Short Term Bond ETF	[0.20]%

From time to time, the Adviser may waive all or a portion of its management fee. [The Adviser has contractually agreed to waive a portion of its management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for each Fund until October 31, 2022. This waiver and/or reimbursement does not provide for the recoupment by the Adviser of any amounts waived or reimbursed. This waiver and/or reimbursement may not be terminated prior to October 31, 2022 except with the approval of the Board.] The Adviser pays all expenses of each Fund other than the management fee, brokerage expenses, taxes, interest, fees and expenses of the Independent Trustees (including any Trustee's counsel fees), litigation expenses and other extraordinary expenses.

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

[Blackstone Liquid Credit Strategies LLC serves as the investment sub-adviser to the SPDR Blackstone Senior Loan ETF, and is responsible for providing the investment program for the Fund.

PORTFOLIO MANAGERS

SPDR SSGA Ultra Short Term Bond ETF

The Adviser manages the Fund using a team of investment professionals. The team approach is used to create an environment that encourages the flow of investment ideas. The portfolio managers within each team work together in a cohesive manner to develop and enhance techniques that drive the investment process for the respective investment strategy. This approach requires portfolio managers to share a variety of responsibilities including investment strategy and analysis while retaining responsibility for the implementation of the strategy within any particular portfolio. The approach also enables the team to draw upon the resources of other groups within SSGA. The portfolio management team is overseen by the SSGA Investment Committee.

Additional Purchase and Sale Information

Fund Shares are listed for secondary trading on the Exchange and individual Fund Shares may only be purchased and sold in the secondary market through a broker-dealer. The secondary markets are closed on weekends and also are generally closed on the following holidays: New Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day (observed), Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Exchange may close early on the business day before certain holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If you buy or sell Fund Shares in the secondary market, you will pay the secondary market price for Fund Shares. In addition, you may incur customary brokerage commissions and charges and may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

The trading prices of Fund Shares will fluctuate continuously throughout trading hours based on market supply and demand rather than the relevant Fund's net asset value, which is calculated at the end of each business day. Fund Shares will trade on the Exchange at prices that may be above (i.e., at a premium) or below (i.e., at a discount), to varying degrees, the daily net asset value of Fund Shares. The trading prices of Fund Shares may deviate significantly from the relevant Fund's net asset value during periods of market volatility. Given, however, that Fund Shares can be issued and redeemed daily in Creation Units, the Adviser believes that large discounts and premiums to net asset value should not be sustained over long periods.

The Exchange will disseminate, every fifteen seconds during the regular trading day, an indicative optimized portfolio value (“IOPV”) relating to each Fund. The IOPV calculations are estimates of the value of each Fund's net asset value per Fund Share. Premiums and discounts between the IOPV and the market price may occur. This should not be

Table of Contents

viewed as a “real-time” update of the net asset value per Fund Share. The IOPV is based on the current market value of the published basket of portfolio securities and/or cash required to be deposited in exchange for a Creation Unit and does not necessarily reflect the precise composition of a Fund's actual portfolio at a particular point in time. Moreover, the IOPV is generally determined by using current market quotations and/or price quotations obtained from broker-dealers and other market intermediaries and valuations based on current market rates. The IOPV may not be calculated in the same manner as the NAV, which (i) is computed only once a day, (ii) unlike the calculation of the IOPV, takes into account Fund expenses, and (iii) may be subject, in accordance with the requirements of the 1940 Act, to fair valuation at different prices than those used in the calculations of the IOPV. The IOPV price is based on quotes and closing prices from the securities' local market converted into U.S. dollars at the current currency rates and may not reflect events that occur subsequent to the local market's close. Therefore, the IOPV may not reflect the best possible valuation of a Fund's current portfolio. Neither the Funds nor the Adviser or any of their affiliates are involved in, or responsible for, the calculation or dissemination of such IOPVs and make no warranty as to their accuracy.

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

Distributions

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

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

Income dividend distributions, if any, for the Funds are generally distributed to shareholders monthly, but may vary significantly from period to period.

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

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

Portfolio Holdings Disclosure

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

Table of Contents

Additional Tax Information

The following discussion is a summary of some important U.S. federal income tax considerations generally applicable to an investment in a Fund. Your investment in a Fund may have other tax implications. Please consult your tax advisor about federal, state, local, foreign or other tax laws applicable to you. Investors, including non-U.S. investors, may wish to consult the SAI tax section for additional disclosure.

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

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

In general, dividends may be reported by a Fund as qualified dividend income if they are attributable to qualified dividend income received by the Fund, which, in general, includes dividend income from taxable U.S. corporations and certain foreign corporations (i.e., certain foreign corporations incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, and certain other foreign corporations if the stock with respect to which the dividend is paid is readily tradable on an established securities market in the United States), provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. A dividend generally will not be treated as qualified dividend income if the dividend is received with respect to any share of stock held by a Fund for fewer than 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, for fewer than 91 days during the 181-day period beginning 90 days before such date. These holding period requirements will also apply to your ownership of Fund Shares. Holding periods may be suspended for these purposes for stock that is hedged. Additionally, income derived in connection with a Fund's securities lending activities will not be treated as qualified dividend income. Since the Funds primarily hold investments that do not pay dividends, it is not expected that a substantial portion of the dividends paid by these Funds will qualify for either the dividends-received deduction for corporations or the favorable income tax rates available to individuals on qualified dividend income. Additionally, dividends paid on fund shares on loan will not be treated as qualified dividend income.

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

Certain tax-exempt educational institutions will be subject to a 1.4% tax on net investment income. For these purposes, certain dividends and capital gain distributions, and certain gains from the disposition of Fund Shares (among other categories of income), are generally taken into account in computing a shareholder's net investment income.

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

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

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

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

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

Market Discount. Any market discount recognized on a market discount bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value or below adjusted issue price if the bond was issued with original issue discount. Absent an election by a Fund to include the market discount in income as it accrues, the gain on the Fund's disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount. Where the income required to be recognized as a result of the market discount rules is not matched by a corresponding cash receipt by the Fund, the Fund may be required to borrow money or dispose of securities to enable the Fund to make distributions to its shareholders in order to qualify for treatment as a regulated investment company and eliminate taxes at the Fund level, potentially resulting in additional taxable gain or loss to the Fund.

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

Foreign Currency Transactions. A Fund's transactions in foreign currencies, foreign currency denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned.

Foreign Income Taxes. Investment income received by a Fund from sources within foreign countries may be subject to foreign income taxes withheld at the source. The United States has entered into tax treaties with many foreign countries which may entitle a Fund to a reduced rate of such taxes or exemption from taxes on such income. It is impossible to determine the effective rate of foreign tax for a Fund in advance since the amount of the assets to be invested within various countries is not known. If more than 50% of the total assets of a Fund at the close of its taxable year consist of certain foreign stocks or securities, the Fund may elect to “pass through” to you certain foreign income taxes (including withholding taxes) paid by the Fund. If at least 50% of a Fund's assets consist of stock of other regulated investment companies, the Fund may also make such an election. If a Fund in which you hold Fund

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

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

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

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

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

The Trust on behalf of each Fund has the right to reject an order for Creation Units if the purchaser (or a group of purchasers) would, upon obtaining the Fund Shares so ordered, own 80% or more of the outstanding shares of the applicable Fund and if, pursuant to Section 351 of the Internal Revenue Code, the applicable Fund would have a basis in the securities different from the market value of the securities on the date of deposit. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination. If the Trust does issue Creation Units to a purchaser (or a group of purchasers) that would, upon obtaining the Fund Shares so ordered, own 80% or more of the outstanding shares of the applicable Fund, the purchaser (or group of purchasers) will not recognize gain or loss upon the exchange of securities for Creation Units.

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

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

Investments In Certain Foreign Corporations. A Fund may invest in foreign entities classified as passive foreign investment companies or “PFICs” or controlled foreign corporations or “CFCs” under the Internal Revenue Code. PFIC and CFC investments are subject to complex rules that may under certain circumstances adversely affect a Fund. Accordingly, investors should consult their own tax advisors and carefully consider the tax consequences of PFIC and

Table of Contents

CFC investments by a Fund before making an investment in such Fund. Fund dividends attributable to dividends received from PFICs generally will not be treated as qualified dividend income. Additional information pertaining to the potential tax consequences to the Funds, and to the shareholders, from the Funds' potential investment in PFICs and CFCs can be found in the SAI.

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

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

Backup Withholding. A Fund will be required in certain cases to withhold (as “backup withholding”) on amounts payable to any shareholder who (1) has provided the Fund either an incorrect tax identification number or no number at all, (2) is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, (3) has failed to certify to the Fund that such shareholder is not subject to backup withholding, or (4) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is currently 24%. Backup withholding will not be applied to payments that have been subject to the 30% withholding tax on shareholders who are neither citizens nor permanent residents of the United States.

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

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

General Information

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

Management and Organization

Each Fund is a separate series of the Trust, which is an open-end registered management investment company.

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

The Trust has received exemptive relief from Section 12(d)(1) to allow registered investment companies to invest in certain Funds beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions as set forth in an SEC exemptive order issued to the Trust, including that such investment companies enter into an agreement with the Trust. This order will be rescinded by the SEC on January 19, 2022. However, effective January 19, 2021, new Rule 12d1-4 permits other investment companies to invest in the Funds beyond the limits in Section 12(d)(1), subject to similar conditions.

fTable of Contents

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

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

Financial Highlights

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