SPDR Index Shares

Before you invest in the SPDR S&P Global Infrastructure ETF (the “Fund”), you may want to review the Fund’s prospectus and statement of additional information, which contain more information about the Fund and the risks of investing in the Fund. The Fund’s prospectus and statement of additional information dated January 31, 2013, are incorporated by reference into this summary prospectus. You can find the Fund’s prospectus and statement of additional information, as well as other information about the Fund, online at https://www.spdrs.com/product/fund.seam?ticker=GII.

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.

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:

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 10% of the average value of its portfolio.

In seeking to track the performance of the S&P Global Infrastructure 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. SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment

adviser to the Fund, generally expects the Fund to hold less than the total number of securities in the Index, but reserves the right to hold as many securities as it believes necessary to achieve the Fund’s investment objective.

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 American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”) based on securities comprising 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 equity 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 the Adviser).

The Index is comprised of 75 of the largest publicly listed infrastructure companies that meet specific investability requirements. The index is designed to provide liquid exposure to the leading publicly listed companies in the global infrastructure industry, from both developed markets and emerging markets. The Index includes publicly traded companies with stock traded on a developed market exchange with float-adjusted market capitalizations of a minimum of $100 million and minimum total market capitalizations of $250 million. Liquidity thresholds on 3 month average daily trading are $1 million for developed markets and $500,000 for emerging markets. Fifteen emerging market stocks are chosen first, based on the highest float-adjusted market capitalization of the parent company, with no more than 10 chosen for any one cluster. The 60 largest developed market stocks, based on float-adjusted market capitalization, are then chosen to complete the index. The developed market stocks are chosen such that there are a total of 30 transportation, 30 utilities and 15 energy infrastructure companies in the Index. Market capitalization and liquidity criteria are subject to change on a semi-annual basis according to market conditions. Countries covered in the Index have historically included, among others, Australia, Brazil, Canada, Chile, China, Denmark, Finland, France, Germany, Hong Kong, India, Italy, Japan, Luxembourg, Netherlands, Norway, Peru, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, United Kingdom and the United States. As of March 31, 2013, the Index was comprised of 75 securities.

The Index is sponsored by S&P Dow Jones Indices LLC (the “Index Provider”), which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

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 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 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.

EQUITY INVESTING RISK: An investment in the Fund involves risks similar to those of investing in any fund of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

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; different practices for clearing and settling trades; 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.

EMERGING MARKETS RISK: Investment in emerging markets subjects 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 a 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.

UTILITIES SECTOR RISK: The Fund’s assets will generally be concentrated in the utilities sector, which means the Fund will be more affected by the performance of the utilities sector than a fund that was more diversified. Stock prices for companies in the utilities sector are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, rate caps or rate changes. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company’s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company’s equipment unusable or obsolete and negatively impact profitability.

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.

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the return before taxes due to the application of foreign tax credits and/or an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective May 1, 2013, the Fund changed its benchmark index to the S&P Global Infrastructure Index. The Fund’s performance prior to May 1, 2013 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

PURCHASE AND SALE INFORMATION

The Fund will issue (or redeem) Shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of 100,000 Shares known as “Creation Units.” Creation Unit transactions are typically conducted in exchange for the deposit or delivery of in-kind securities and/or cash constituting a substantial replication, or a representation, of the securities included in the Fund’s benchmark Index.

Individual Shares of the Fund 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”), Shares may trade at a price greater than NAV (premium) or less than NAV (discount).
