Investment Objective

The State Street Bridgewater All Weather ETF (the "Fund") seeks to achieve long term capital appreciation.

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	0.85%
Distribution and service (12b-1) fees	None
Other expenses	0.00%
Total annual Fund operating expenses	0.85%

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell or hold all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. 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
$87	$271	$471	$1,049

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.  From the Fund's commencement of operations on March 6, 2025 to the most recent fiscal year end, the Fund's portfolio turnover rate was 99% of the average value of its portfolio.

The Fund's Principal Investment Strategy

SSGA Funds Management, Inc. (the "Adviser" or "SSGA FM"), the investment adviser to the Fund, seeks to achieve the Fund's investment objective by investing the Fund's assets based on a model portfolio provided by Bridgewater Associates, LP (the "Sub-Adviser" or "Bridgewater"), the investment sub-adviser to the Fund. The model portfolio includes securities and instruments that provide exposure to different markets and asset classes in proportions which create an overall portfolio that is intended to be resilient across a wide range of market conditions and environments. The model portfolio gains long and short exposure to different asset classes directly and/or through the use of derivative instruments, and has no maximum or minimum exposure to any one asset class.

The Fund may invest in equity securities of domestic and international (including developed and emerging markets) companies of any market capitalization. The Fund may invest in fixed income securities issued or guaranteed by domestic and international corporations or governments, and inflation-linked bonds (such as Treasury Inflation-Protected Securities ("TIPS")). The Fund's fixed income investments may be of any credit quality, including high yield securities. High yield securities (commonly referred to as "junk" bonds or below investment-grade securities) are instruments that are rated BB+ or lower by S&P Global Ratings or Fitch Inc. or Ba1 or lower by Moody's or equivalent ratings by another registered nationally recognized statistical rating organization ("NRSRO"), or, if unrated by an NRSRO, of comparable quality in the opinion of the Adviser. The Fund may obtain exposure to equity and fixed income securities either directly or indirectly through derivative instruments (primarily futures contracts, forwards, currency forwards, swaps and total return swaps) and through exchange traded products ("ETPs"). The Fund's investments in derivatives will create leverage, which may be substantial and may magnify the effect of any increase or decrease in the value of the Fund's portfolio holdings. The Fund may also seek exposure to commodities (e.g., agricultural commodities, energy commodities, and metals commodities) by investing in commodity-based ETPs and a wholly-owned subsidiary, an exempted limited company organized under the laws of the Cayman Islands ("Subsidiary") and managed by the Adviser, that will invest in commodity-linked derivatives (e.g., swaps on commodity indexes and futures contracts on commodities) and commodity-based ETPs. The Fund's investments in the Subsidiary generally provide the Fund with exposure to commodity-linked derivatives and commodity-based ETPs within the limits of the federal tax laws, which limit the ability of investment companies, like the Fund, to invest directly in such instruments. The Fund will not invest more than 25% of its total assets in the Subsidiary. The Fund and the Subsidiary may also invest in cash and cash equivalents or money market instruments (including money market funds advised by SSGA FM), which are intended to provide liquidity, preserve capital, and serve as collateral for the Fund's or Subsidiary's derivative instruments.

Bridgewater provides a daily model portfolio to SSGA FM based on Bridgewater's proprietary All Weather asset allocation approach. The model portfolio is specific to the Fund. Based on Bridgewater's investment recommendations, SSGA FM purchases and sells securities and/or instruments for the Fund. SSGA FM seeks to implement Bridgewater's investment recommendations, but may change the Fund's investment allocation at any time.

Bridgewater's proprietary strategy is an approach to strategic asset allocation that is designed with the goal of generating consistent returns across different economic environments. Bridgewater believes that asset classes have different structural sensitivities to economic conditions that can be logically understood because they are rooted in the characteristics of the asset's cash flows, and that this understanding can be used to structure a portfolio that is diversified to what Bridgewater believes are the most important fundamental macro drivers of asset returns: growth and inflation. For example, allocating to assets that Bridgewater believes will likely outperform in rising growth (e.g., equities and commodities) alongside assets it believes will likely outperform in falling growth (e.g., fixed-rate and inflation-linked bonds) can create a portfolio that collects the market risk premium with no fundamental sensitivity to growth conditions. Similarly, allocating to assets that Bridgewater believes will likely outperform in rising inflation (e.g., commodities and inflation-linked bonds) alongside assets it believes will likely outperform in low or stable inflation (e.g., fixed-rate government debt and equities) can create a portfolio that collects the market risk premium with no fundamental sensitivity to inflation. Bridgewater refers to this approach to portfolio diversification as "environmental balance".

In making its investment recommendations to the Fund, Bridgewater will use its proprietary estimates of growth and inflation sensitivity by asset class to specify positions that, in aggregate, create a portfolio that Bridgewater believes has no bias to outperform or underperform based on either growth or inflation conditions, with the goal of enabling the Fund to achieve its investment objective across a wide range of economic environments.

Bridgewater does not vary the weights of investments in the model portfolio based on any tactical view of how particular investments will perform, but rather attempts to balance the risk of the model portfolio based on its understanding of the relationship between asset classes and economic environments. Bridgewater may, however, vary the allocations across and within asset classes based on its assessment of market conditions and evolutions in its understanding of how to best achieve balance to growth and inflation. The model portfolio typically targets an annualized volatility level for the portfolio ranging between 10%-12%. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument, fund, or index over time. Higher volatility generally indicates higher risk. Actual or realized volatility can and may differ from the target volatility range described above. The actual or realized volatility level for longer or shorter periods may be materially higher or lower depending on market conditions.

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

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

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

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 ("NAV") per share and there may be times when the market price of the shares is more than the NAV per share (premium) or less than the NAV per share (discount). This risk is heightened in times of market volatility or periods of steep market declines.

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.

Cash Position Risk: If the Fund holds a significant position in cash or cash equivalents, its investment returns may be adversely affected, and the Fund may underperform other funds that do not similarly invest in cash and cash equivalents for investment purposes and/or to collateralize derivative instruments.

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.

Commodities and Commodity-Linked Derivatives Risk: Commodity prices can have significant volatility, and exposure to commodities can cause the NAV of Fund Shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity investments, which may make it difficult for the Fund to sell them at a desirable price or at the price at which it is carrying them. The value of commodities and commodity-linked derivative instruments typically is based upon the price movements of a physical commodity or an economic variable linked to such price movements. Therefore, the value of commodities and commodity-linked derivative instruments may be affected by, for example, changes in overall market movements, economic conditions, changes in interest rates, or factors affecting a particular commodity or industry, such as production, supply, demand, drought, floods, weather, political, economic and regulatory developments. These factors may impair the ability of the Fund to sell its portfolio holdings quickly or for full value. Commodity-linked derivatives are subject to the risk that the counterparty to the transaction may default or otherwise fail to perform.

Agricultural Commodities Risk: Price movements in agricultural commodities are affected by many factors, some of which include, but are not limited to: farmer planting decisions; weather conditions, including hurricanes, tornadoes, storms and droughts; changes in global supply and demand for agriculture products; the price and quantity of imports and exports of agricultural commodities; general economic, market and regulatory factors; political conditions, including embargoes and war, affecting agricultural production, imports and exports; and technological advances in agricultural production.

Energy Commodities Risk: Energy commodities are subject to frequent, and often substantial, price fluctuations. The markets and prices for energy commodities are affected by many factors, some of which include, but are not limited to: changes in global supply and demand for oil and natural gas; the price and quantity of imports and exports of oil and natural gas; political conditions, including embargoes and war, affecting oil producing activities; the level of global oil and natural gas exploration, inventories, production or pricing; weather conditions; technological advances effecting energy consumption; and the price and availability of alternative fuels.

Metals Commodities Risk: Price movements in metals commodities are affected by many factors. A change in economic conditions, such as a recession, can adversely affect the price of metals. An economic downturn may have a negative impact on the usage and demand of metals, which may result in a loss for the Fund. Other factors affecting prices include, but are not limited to: a sudden shift in political conditions in the world's leading metal producing countries; an increase in the hedging of precious metals; changes in global supply and demand for industrial and precious metals; the price and quantity of imports and exports of industrial and precious metals; and technological advances in the processing and mining of industrial and precious metals.

Commodity-Linked Derivative Tax Risk: To qualify for the favorable U.S. federal income tax treatment accorded to regulated investment companies ("RICs"), the Fund must, among other things, derive in each taxable year at least 90% of its gross income from certain prescribed sources. The Fund generally intends to invest in commodity-linked derivative instruments indirectly through the Subsidiary. The Fund's investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the federal tax requirements of the Code for qualification as a RIC. The Adviser intends to conduct the Fund's investments in the Subsidiary in a manner consistent with the terms and conditions of the regulations promulgated by the U.S. Treasury, and will monitor the Fund's investments in the Subsidiary to ensure that no more than 25% of the Fund's total assets are invested in the Subsidiary.

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

Emerging Markets Risk: Risks of investing in emerging markets include, among others, greater political and economic instability, greater volatility in currency exchange rates, less developed securities markets, increased potential for market manipulation, possible trade barriers, currency transfer restrictions, a more limited number of potential buyers and issuers, an emerging market country's dependence on revenue from particular commodities or international aid, less governmental supervision and regulation, unavailability of currency hedging techniques, differences in auditing and financial reporting standards, and less developed legal systems. There is also the potential for unfavorable action such as expropriation, nationalization, embargoes, and acts of war. The securities of emerging market companies may trade less frequently and in smaller volumes than more widely held securities. Market disruptions or substantial market corrections may limit very significantly the liquidity of securities of certain companies in a particular country or geographic region, or of all companies in the country or region. The Fund may be unable to liquidate its positions in such securities at any time, or at a favorable price, in order to meet the Fund's obligations. These risks are generally greater for investments in frontier market countries, which typically have smaller economies or less developed capital markets than traditional emerging market countries.

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 NAV of an exchange traded fund's ("ETF") shares) for a number of reasons. For example, supply and demand for shares of an ETF or market disruptions may cause the market price of the ETF to deviate from the value of the ETF's investments, which may be exacerbated in less liquid markets. The value of an exchange traded note may also differ from the valuation of its reference market due to changes in the issuer's credit rating.

Forward Contracts Risk: A forward contract is a private, customizable agreement to buy or sell a specified currency, security or instrument at a future date at a price set at the time of the contract. Forward contracts settle at the end of the agreement and trade over-the-counter. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. A non-deliverable forward currency contract is a contract where there is no physical settlement of two currencies at maturity. Instead, a net cash settlement will be made by one party to the other based on the movement of the

currencies. The risks of forward contracts include, but are not limited to: (1) the success of the Adviser's ability to predict movements in the prices of individual currencies or securities, fluctuations in markets and movements in interest rates; (2) imperfect or no correlation between the changes in market value of the currencies or securities and the prices of such contracts; and (3) the risk that the counterparty will default on its obligations.

Futures Contract Risk: A futures contract is a standardized agreement that calls for the purchase or sale of a specific asset at a specific price at a specific future time, or cash settlement of the terms of the contract. Transactions in futures contracts can create investment leverage and may have significant volatility. It is possible that a futures contract transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out the futures contract at a favorable time or price. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract. In the event no such market exists, it might not be possible to effect closing transactions, and the Fund will be unable to terminate its exposure to the futures contract. There is also a risk of imperfect correlation between movements in the prices of the futures contract and movements in the price of the underlying assets. The counterparty to a futures contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations.

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

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

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

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

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

Limited Track Record Risk: The Fund has a limited track record and there is no assurance that the Fund will grow quickly. When the Fund's size is small, the Fund may experience low trading volume, which could lead to wider bid/ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. Any resulting liquidation of the Fund could cause elevated transaction costs for the Fund and negative tax consequences for its shareholders.

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

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

Mid-Capitalization Securities Risk: The securities of mid-capitalization companies may be more volatile and may involve more risk than the securities of larger companies. These companies may have limited product lines, markets or financial resources, may lack the competitive strength of larger companies, and may depend on a few key employees. In addition, these companies may have been recently organized and may have little or no track record of success. The securities of mid-sized companies may trade less frequently and in smaller volumes than more widely held securities. Some securities of mid-sized issuers may be illiquid or may be restricted as to resale, and their values may be volatile.

Money Market Fund Investment Risk: An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. 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.

Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. 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 investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. In addition, to the extent that the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. Certain countries may institute 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.

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

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. 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.

Subsidiary Investment Risk: The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the "1940 Act") and is not subject to all of the investor protections of the 1940 Act. Thus, the Fund, as an investor in the Subsidiary, will not have all of the protections offered to investors in registered investment companies. In addition, changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund to operate as intended and could negatively affect the Fund and its shareholders.

Swaps Risk: A swap is a two-party contract that generally obligates the parties to exchange payments based 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). It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

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.

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

Valuation Risk: Certain portfolio holdings 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.

Fund Performance

The Fund has not yet completed a full calendar year of operations and therefore does not report its performance history. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's returns based on net assets and comparing the Fund's performance to an index. Updated performance information may be obtained by calling 1-866-787-2257 or visiting the Fund's website: www.statestreet.com/im.

Portfolio Management

Investment Adviser and Sub-Adviser

SSGA FM serves as the investment adviser to the Fund. Bridgewater 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 Bridgewater, where the context requires with respect to its obligations and the terms of the sub-advisory agreement. Bridgewater does not oversee the day-to-day investment activities of the Fund and is not a party to any direct contractual agreement with the Fund.

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.

Individual Fund Shares may only be purchased and sold on The Nasdaq Stock Market LLC (the "Exchange"), other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at 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 www.statestreet.com/im.

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 a 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.
