SPDR(R) Barclays International High Yield Bond ETF

FUND SUMMARY

SPDR^® Barclays International High Yield Bond ETF

INVESTMENT OBJECTIVE

The SPDR Barclays International High Yield Bond ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of an index that tracks the high yield corporate bond market of non-US issuers.

FEES AND EXPENSES OF THE FUND

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.

ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):

Annual Fund Operating Expenses		SPDR(R) Barclays International High Yield Bond ETF
MANAGEMENT FEES		0.40%
DISTRIBUTION AND SERVICE (12b-1) FEES	[1]	none
OTHER EXPENSES	[2]	none
TOTAL ANNUAL FUND OPERATING EXPENSES		0.40%

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 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:

Expense Example (USD $)	YEAR 1	YEAR 3
SPDR(R) Barclays International High Yield Bond ETF	41	128

PORTFOLIO TURNOVER:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

In seeking to track the performance of the Barclays Global HY ex US Domiciled 350mn+ Cash Pay Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. Based on its analysis of these factors, State Street Global Advisors Limited (“SSgA LTD” or the “Sub-Adviser”), the investment sub-adviser to the Fund, may invest the Fund’s assets in a subset of securities in the Index or may invest the Fund’s assets in substantially all of the securities represented in the Index in approximately the same proportions as the Index.

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index or in securities that the Sub-Adviser determines have economic characteristics substantially identical to the economic characteristics of the securities that comprise the Index. The Fund will provide shareholders with at least 60 days’ notice prior to any material change in this 80% investment policy. In addition, the Fund may invest in debt securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is designed to be a measure of the international high yield, fixed rate, fixed income corporate markets of issuers domiciled outside the United States, including in emerging markets. High yield securities are generally rated below investment grade and are commonly referred to as “junk bonds.” The securities in the Index must have a minimum 350 million market capitalization outstanding in local currency terms and at least 1 year remaining to maturity. Securities must be fixed rate, although step-up coupons and coupons that change according to a predetermined schedule are permitted. Additionally, securities must be rated high yield (Ba1/BB+/BB+ or below), but not defaulted, using the middle rating of Moody’s Investors Service, Inc., Standard & Poor’s, Inc., and Fitch Inc. after dropping the highest and lowest available ratings. When a rating from only two agencies is available, the lower (“more conservative”) rating is used. When a rating from only one agency is available, that rating is used to determine Index eligibility. Excluded from the Index are convertible securities, floating-rate notes, warrants, linked bonds, structured products, zero coupon bonds, and payment in kind securities. Each Index eligible issuer is capped at two percent. The Index is market capitalization weighted and the securities in the Index are updated on the last business day of each month. As of January 31, 2014, the Index was comprised of 702 securities. As of March 7, 2014, the following countries were represented in the Index Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, Croatia, Czech Republic, Dominican Republic, Finland, France, Germany, Greece, Guatemala, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Luxembourg, Macau, Mexico, Mongolia, Netherlands, Nigeria, Norway, Poland, Portugal, Russia, South Africa, South Korea, Serbia, Singapore, Spain, Sweden, Switzerland, Turkey, Ukraine, the United Kingdom and the United States.

The Index is sponsored by Barclays, Inc. (the “Index Provider”) which is not affiliated with the Fund, the Adviser, or the Sub-Adviser. The Index Provider determines the composition of the Index and relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

PRINCIPAL RISKS OF INVESTING IN THE FUND

As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

PASSIVE STRATEGY/INDEX RISK:  The Fund is managed with a passive investment strategy, attempting to track the performance of an unmanaged index of securities. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold constituent securities of the Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

INDEX TRACKING RISK:  While the Sub-Adviser seeks to track the performance of the Index as closely as possible (i.e., achieve a high degree of correlation with the Index), the Fund’s return may not match or achieve a high degree of correlation with the return of the Index due to operating expenses, transaction costs, cash flows, regulatory requirements and operational inefficiencies. For example, the Sub-Adviser anticipates that it may take several business days for additions and deletions to the Index to be reflected in the portfolio composition of the Fund.

DEBT SECURITIES INVESTING RISK:  The value of the debt securities may increase or decrease as a result of the following: market fluctuations, increases in interest rates, inability of issuers to repay principal and interest 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. This may result in a reduction in income from debt securities income.

FOREIGN INVESTMENT RISK:  Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in securities issued by entities based outside the U.S. pose distinct risks since political and economic events unique to a country or region will affect those markets and their issuers. Further, such entities and/or their securities may also be affected by currency controls; different accounting, auditing, financial reporting, and legal standards and practices; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. In addition, the value of the currency of the country in which the Fund has invested could decline relative to the value of the U.S. dollar, which may affect the value of the investment to U.S. investors. These risks may be heightened in connection with investments in developing or emerging countries.

GEOGRAPHIC RISK:  Funds that are less diversified across countries or geographic regions are generally riskier than more geographically diversified funds. For example, a Fund that focuses on a single country (e.g., China or Japan), or a specific region (e.g., the Middle East or African countries) is more exposed to that country’s or region’s economic cycles, currency exchange rates, stock market valuations and political risks compared with a more geographically diversified fund. The economies and financial markets of certain regions, such as Latin America, Asia or Eastern Europe, can be interdependent and may decline all at the same time.

EUROPE:  Developed and emerging market countries in Europe will be significantly affected by the fiscal and monetary controls of the European Monetary Union. Changes in regulations on trade, decreasing imports or exports, changes in the exchange rate of the euro and recessions among European countries may have a significant adverse effect on the economies of other European countries including those of Eastern Europe. The markets in Eastern Europe remain relatively undeveloped and can be particularly sensitive to political and economic developments.

EMERGING MARKETS RISK:  Investments in emerging markets subject the Fund to a greater risk of loss than investments in a developed market. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, high levels of inflation, deflation or currency devaluation, greater risk of market shut down, and more governmental limitations on foreign investment policy than those typically found in a developed market. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than in other countries. As a result, there will tend to be an increased risk of price volatility in the Fund’s investments in emerging market countries, which may be magnified by currency fluctuations relative to the U.S. dollar. Settlement practices for transactions in foreign markets may differ from those in U.S. markets. Such differences include delays beyond periods customary in the United States and practices, such as delivery of securities prior to receipt of payment, which increase the likelihood of a “failed settlement.” Failed settlements can result in losses to the Fund. For these and other reasons, investments in emerging markets are often considered speculative.

HIGH YIELD SECURITIES RISK:  Securities rated below investment grade, commonly referred to as “junk bonds,” include bonds that are rated Ba1/BB+/BB+ or below by Moody’s Investors Service, Inc., Fitch Inc., or Standard & Poor’s, Inc., respectively, or unrated securities considered to be of equivalent quality by the Sub-Adviser, and may involve greater risks than securities in higher rating categories. Such bonds are regarded as speculative in nature, involve greater risk of default by the issuing entity and may be subject to greater market fluctuations than higher rated fixed income securities. They are usually issued by companies without long track records of sales and earnings, or by those companies with questionable credit strength. The retail secondary market for these “junk bonds” may be less liquid than that of higher rated securities and adverse conditions could make it difficult at times to sell certain securities or could result in lower prices than those used in calculating the Fund’s net asset value. When the Fund invests in “junk bonds,” it may also be subject to greater credit risk because it may hold debt securities issued in connection with corporate restructuring by highly leveraged issuers or in debt securities not current in the payment of interest or principal or in default.

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 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 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 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.

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, and the interest rates and fees they can charge. 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, the recent deterioration of the credit markets generally has caused 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. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. 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.

NON-DIVERSIFICATION RISK:  The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or a single issuer than that of a diversified fund. As a result, the Fund’s performance may be disproportionately impacted by the performance of relatively few securities.

FUND PERFORMANCE

The Fund has not yet completed a full calendar year of investment operations and therefore does not have any performance history. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund’s returns based on net assets and comparing the Fund’s performance to the Index.

[1] The Fund has adopted a Distribution and Service (12b-1) Plan pursuant to which payments of up to 0.25% of average daily net assets may be made, however, the Board has determined that no such payments will be made through the next twelve (12) months of operation.

[2] “Other Expenses” are based on estimated amounts for the current fiscal year.
