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&#8217;s operating expenses remain the same.

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&#8217;s performance. During the most recent fiscal year, the Fund&#8217;s portfolio turnover rate was 3% of the average value of its portfolio. </font> <font style="FONT-FAMILY: Arial" size="2"><b>THE FUND&#8217;S PRINCIPAL INVESTMENT STRATEGY</b></font> <font style="FONT-FAMILY: ARIAL" size="2">In seeking to track the performance of the Dow Jones U.S. Total Stock Market Index (the &#8220;Index&#8221;), 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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the 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). </font> <br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is designed to represent the performance of all U.S. equity securities, including business development companies, with readily available price data. The Index tracks all the U.S. common stocks regularly traded on the New York Stock Exchange, NYSE Amex and the NASDAQ Stock Market. The Index is a float-adjusted market capitalization weighted index that reflects shares of securities actually available to investors in the marketplace. To be included in the Index, an issue generally must be all of the following: (i) a company&#8217;s primary equity issue (common stock, REIT or limited partnership); and (ii) the security of a U.S. company. A semiannual composition review of the Index is announced and implemented in March and September. Shares and float factors of the Index are updated on a quarterly basis.

The selection universe for the S&amp;P 500 Index includes all U.S. common equities listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally of $4.0 billion or more at the time of inclusion.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>LARGE CAP RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;Returns on investments in stocks of large U.S. companies could trail the returns on investments in stocks of smaller and mid-sized companies. </font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>GROWTH RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;The Fund emphasizes a &#8220;growth&#8221; style of investing. The market values of growth stocks may be more volatile than other types of investments. The prices of growth stocks tend to reflect future expectations, and when those expectations change or are not met, share prices generally fall.

The reason for the exclusions is that factors other than real estate supply and demand, such as interest rates, influence the market value of these companies. The Index is a market capitalization weighted index of publicly traded real estate investment trusts (&#8220;REITs&#8221;) and is comprised of companies whose charters are the equity ownership and operation of commercial real estate and which operate under the REIT Act of 1960. To be included in the Index, a company must be both an equity owner and operator of commercial and/or residential real estate. Businesses excluded from the Index include: mortgage REITs, net-lease REITs, real estate finance companies, mortgage brokers and bankers, commercial and residential real estate brokers and real estate agents, home builders, large landowners and subdividers of unimproved land, hybrid REITs, and timber REITs, as well as companies that have more than 25% of their assets in direct mortgage investments. A company must have a minimum total market capitalization of at least $200 million at the time of its inclusion, and at least 75% of the company&#8217;s total revenue must be derived from the ownership and operation of real estate assets. The liquidity of the company&#8217;s stock must be commensurate with that of other institutionally held real estate securities. The Index is generally rebalanced quarterly, and returns are calculated on a buy and hold basis except as necessary to reflect the occasional occurrence of Index changes in the middle of the month. Each REIT in the Index is weighted by its float-adjusted market capitalization. That is, each security is weighted to reflect the attainable market performance of the security which reflects that portion of securities shares that are accessible to investors. The Index is priced daily and is a total return (price and income) benchmark. As of September 30, 2012, the Index was comprised of 85 REITs. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund, the Adviser or the Sub-Adviser (as defined below).

Adverse economic, business or political developments affecting real estate could have a major effect on the value of the Fund&#8217;s investments. Investing in real estate securities (which include REITs) may subject the Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent and fluctuations in rental income. Changes in interest rates may also affect the value of the Fund&#8217;s investment in real estate securities. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers. In addition, a REIT could fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended and could fail to maintain exemption from the registration requirements of the Investment Company Act of 1940, as amended. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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.

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&#8217;s return to be lower than if the Fund employed an active strategy.</font> <br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: Arial" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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.

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. These risks may be heightened in connection with investments in developing or emerging countries.</font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"> <b>EMERGING MARKETS RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: Arial" size="2">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&#8217;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 &#8220;failed settlement.&#8221; Failed settlements can result in losses to the Fund. For these and other reasons, investments in emerging markets are often considered speculative.</font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: Arial" size="2">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.</font><br /><br /> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: Arial" size="2">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.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $2 billion with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 100%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $1 biillion or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market.

The performance of bank stocks may be affected by 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 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. Credit losses resulting from financial difficulties of borrowers can negatively impact the sector. Banks may also be subject to severe price competition.

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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS).

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.

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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective. </font><br /><br /><font style="FONT-FAMILY: ARIAL" size="2">Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index.

Stocks included in the Index have both capital growth and dividend income characteristics, as opposed to stocks that are pure yield, or pure capital oriented, and must meet minimum float-adjusted market capitalization and liquidity requirements. Stocks within the Index are weighted by indicated yield (annualized gross dividend payment per share divided by price per share) and weight-adjusted each quarter. The Index components are reviewed annually in January for continued inclusion in the Index and re-weighted quarterly in April, July and October. A component stock may be removed from the Index if, among other factors, 1) during the January rebalancing, dividends did not increase from the previous year, or 2) at any time during the year, a company is removed from the S&amp;P Composite 1500 Index.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index.

The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization.

The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 48 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font> &nbsp;<font style="FONT-FAMILY: ARIAL" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>BIOTECHNOLOGY SECTOR RISK:</b></font> &nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The Fund&#8217;s assets will generally be concentrated in the biotechnology industry, which means the Fund will be more affected by the performance of the biotechnology industry versus a fund that was more diversified. Companies within the biotech industry invest heavily in research and development which may not necessarily lead to commercially successful products. This industry is also subject to increased governmental regulation which may delay or inhibit the release of new products. Many biotech companies are dependent upon their ability to use and enforce intellectual property rights and patents. Any impairment of such rights may have adverse financial consequences. Biotech stocks, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Biotech companies can be significantly affected by technological change and obsolescence, product liability lawsuits and consequential high insurance costs. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>HEALTH CARE SECTOR RISK:</b></font> &nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font> &nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font> &nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund&#8217;s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market.

The market for products is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer&#8217;s products or in the market for products based on a particular technology could have a material adverse effect on a participant&#8217;s operating results. Companies in the electronics industry may rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by such companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies&#8217; technology. </font> <br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements.

The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market.

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.

Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index.

The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products and the ability to service such products.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap 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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective.<br/><br/>Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities, including business development companies, 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).<br/><br/> The Index applies an alternative weighting methodology to the S&amp;P Composite 1500 Index so that stocks with relatively low valuations (i.e., relatively &#8220;cheap&#8221;) are overweight relative to the S&amp;P Composite 1500 Index and stocks with relatively high valuations (i.e., relatively &#8220;rich&#8221;) are underweight. The S&amp;P Composite 1500 Index, one of the leading indices of the U.S. equity market, is a capitalization-weighted combination of the large-cap S&amp;P 500 Index, the S&amp;P MidCap 400 Index, and the S&amp;P SmallCap 600 Index. In constructing the Index, S&amp;P Dow Jones Indices LLC (&#8220;Index Provider&#8221;) estimates the valuation of each stock in the S&amp;P Composite 1500 Index based on the ratio of its price to its level of earnings, cash flow, sales, book value, and dividends. S&amp;P weights this data from the last five calendar years to create a composite valuation measure, and ranks all 1,500 index constituents in order of composite valuation. S&amp;P then forms 20 sub-portfolios of approximately equal market capitalization, grouped by composite valuations. S&amp;P derives a sub-portfolio allocation factor using each sub-portfolio&#8217;s composite valuation, so that a sub-portfolio with relatively low valuation will have a higher allocation factor than a sub-portfolio with relatively high valuation. The weight of each stock in the Index is proportionate to its market capitalization and to its sub-portfolio allocation factor. The Index is rebalanced annually after the close of business on the third Friday of April.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 31 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b> </font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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.

Companies in the pharmaceutical industry are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of the companies. Pharmaceutical companies are also subject to extensive litigation based on product liability and other similar claims. Many new products are subject to approval of the U.S. Food and Drug Administration (&#8220;FDA&#8221;). The process of obtaining FDA approval can be long and costly and approved products are susceptible to obsolescence. Pharmaceutical companies are also subject to heavy competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>HEALTH CARE SECTOR RISK:</b>&nbsp;&nbsp; </font><font style="FONT-FAMILY: ARIAL" size="2">Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

The information technology consulting services and outsourcing industry can be significantly affected by competitive pressures, such as technological developments, fixed-rate pricing, and the ability to attract and retain skilled employees. The success of companies in this industry is subject to continued demand for business services. </font> <br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>COMPUTER SECTOR RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;The Fund will concentrate in segments of the computer industry. The computer industry can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer&#8217;s products or in the market for products based on a particular technology could have a material adverse effect on a participant&#8217;s operating results. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="2">Many computer companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies&#8217; technology. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>TECHNOLOGY SECTOR RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund&#8217;s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap 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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities, including business development companies, comprising the Index.

The S&amp;P Composite 1500 Index, one of the leading indices of the U.S. equity market, is a capitalization-weighted combination of the large-cap S&amp;P 500 Index, the S&amp;P MidCap 400 Index, and the S&amp;P SmallCap 600 Index. A &#8220;momentum&#8221; style of investing emphasizes investing in securities that have had higher recent price performance compared to other securities. In constructing the Index, S&amp;P Dow Jones Indices LLC (&#8220;Index Provider&#8221;) estimates the momentum of each stock in the S&amp;P Composite 1500 Index based on its price performance over the 11 months ending one month before the index rebalancing date, and ranks all 1,500 Index constituents in order of momentum. S&amp;P then forms 20 sub-portfolios of approximately equal market capitalization, grouped by momentum. S&amp;P defines a sub-portfolio allocation factor so that a sub-portfolio with relatively high momentum will have a higher allocation factor than a sub-portfolio with relatively low momentum. The weight of each stock in the Index is proportionate to its market capitalization and to its sub-portfolio allocation factor. The Index is rebalanced quarterly on or about the end of January, April, July, and October.

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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities, including business development companies, 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). </font> <br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index applies an alternative weighting methodology to the S&amp;P Composite 1500 Index so that stocks with relatively low volatility are overweight relative to the S&amp;P Composite 1500 Index and stocks with relatively high volatility are underweight. The S&amp;P 1500 Index, one of the leading indices of the U.S. equity market, is a capitalization-weighted combination of the large-cap S&amp;P 500 Index, the S&amp;P MidCap 400 Index, and the S&amp;P SmallCap 600 Index. In constructing the Index, S&amp;P Dow Jones Indices LLC estimates the volatility of each stock in the S&amp;P Composite 1500 Index based on its monthly price return variance over the past five years, and ranks all 1,500 index constituents in order of volatility. S&amp;P then forms 20 sub-portfolios of approximately equal market capitalization, grouped by volatility. S&amp;P derives a sub-portfolio allocation factor using the inverse of each sub-portfolio&#8217;s volatility, so that a sub-portfolio with relatively low volatility will have a higher allocation factor than a sub-portfolio with relatively high volatility. The weight of each stock in the Index is proportionate to its market capitalization and to its sub-portfolio allocation factor. The Index is rebalanced annually after the close of business on the third Friday of April. As of September 30, 2012, there were approximately 1,500 securities in the Index.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

Generally, Preferred Security holders (such as the Fund) have no voting rights with respect to the issuing company unless certain events occur. In addition, Preferred Securities are subordinated to bonds and other debt instruments in a company&#8217;s capital structure and therefore will be subject to greater credit risk than those debt instruments. Unlike debt securities, dividend payments on a Preferred Security typically must be declared by the issuer&#8217;s board of directors. An issuer&#8217;s board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on Preferred Securities at any time. In the event an issuer of Preferred Securities experiences economic difficulties, the issuer&#8217;s Preferred Securities may lose substantial value due to the reduced likelihood that the issuer&#8217;s board of directors will declare a dividend and the fact that the Preferred Security may be subordinated to other securities of the same issuer. There is a chance that the issuer of any of the Fund&#8217;s holdings will default (fail to make scheduled dividend payments on the Preferred Security or scheduled interest payments on other obligations of the issuer not held by the Fund).</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INTEREST RATE RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Because many Preferred Securities pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds &#8212; that is, as interest rates rise, the value of the Preferred Securities held by the Fund are likely to decline. To the extent that the Fund invests a substantial portion of its assets in fixed rate Preferred Securities, rising interest rates may cause the value of the Fund&#8217;s investments to decline significantly.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>ISSUER RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Because many Preferred Securities allow holders to convert the Preferred Securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer&#8217;s common stock and, therefore, declining common stock values may also cause the value of the Fund&#8217;s investments to decline.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>CALL RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Preferred Securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a Preferred Security having a higher than average yield may cause a decrease in the Fund&#8217;s yield.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>FINANCIAL SECTOR RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Preferred Securities may be issued by financial institutions. Financial institutions 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 caused certain financial institutions to incur large losses. Numerous financial institutions 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 institutions 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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>FOREIGN SECURITIES RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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. These risks may be heightened in connection with investments in developing or emerging countries.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market.

These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund&#8217;s performance.

SPDR(R) S&P(R) Aerospace & Defense ETF
SPDR® S&P® Aerospace & Defense ETF
INVESTMENT OBJECTIVE
The SPDR S&P Aerospace & Defense ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the aerospace and defense segment of a U.S. total market composite index.
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) S&P(R) Aerospace & Defense ETF
MANAGEMENT FEES 0.35%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
TOTAL ANNUAL FUND OPERATING EXPENSES 0.35%
[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 at least October 31, 2013.
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:

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 period from the commencement of the Fund’s operations (September 28, 2011) to the end of the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Aerospace & Defense Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the aerospace and defense industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 37 stocks.

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.
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 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.

AEROSPACE AND DEFENSE SECTOR RISK:  The Fund’s assets will generally be concentrated in the aerospace and defense industry, which means the Fund will be more affected by the performance of the aerospace and defense industry versus a fund that was more diversified. The aerospace and defense industry can be significantly affected by government aerospace and defense regulation and spending policies because companies involved in this industry rely to a significant extent on U.S. (and other) 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.

INDUSTRIAL SECTOR RISK:  Stock prices for 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 stocks, 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.

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.

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.

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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 31 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b> </font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>PHARMACEUTICALS SECTOR RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The Fund&#8217;s assets will generally be concentrated in the pharmaceuticals industry, which means the Fund will be more affected by the performance of the pharmaceuticals industry versus a fund that was more diversified. Companies in the pharmaceutical industry are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of the companies. Pharmaceutical companies are also subject to extensive litigation based on product liability and other similar claims. Many new products are subject to approval of the U.S. Food and Drug Administration (&#8220;FDA&#8221;). The process of obtaining FDA approval can be long and costly and approved products are susceptible to obsolescence. Pharmaceutical companies are also subject to heavy competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>HEALTH CARE SECTOR RISK:</b>&nbsp;&nbsp; </font><font style="FONT-FAMILY: ARIAL" size="2">Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

The Index includes the components of the Total Stock Market Index ranked approximately 1-750 by full market capitalization. The composition of the Index is assigned based on the semiannual review of the Total Stock Market Index. New issues are added to the Index on a monthly basis as new issues are added to the Total Stock Market Index and fall within the large cap portion. An issue is removed as soon as prudently possible if it fails to meet the inclusion requirement of the Total Stock Market Index.

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.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 58 stocks. </font><br /><br /><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br /><br /> <b><font style="FONT-FAMILY: ARIAL" size="1">INDEX TRACKING RISK:</font></b><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font><br /><br /> <b><font style="FONT-FAMILY: ARIAL" size="1">HEALTH CARE EQUIPMENT SECTOR RISK:</font></b><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;The Fund&#8217;s assets will generally be concentrated in the health care equipment and supplies industry, which means the Fund will be more affected by the performance of the health care equipment and supplies industry versus a fund that was more diversified. Companies in the health care industry are affected by rising costs of medical products, devices and services and the increased emphasis on the delivery of health care through outpatient services. The health care industry is highly competitive and can be significantly affected by extensive government regulation or government reimbursement for medical expenses. The equipment may be subject to extensive litigation based on malpractice claims, product liability claims or other litigation. Medical equipment manufacturers are heavily dependent on patent protection and the expiration of patents may adversely affect their profitability. Many new health care products are subject to the approval of the U.S. Food and Drug Administration (&#8220;FDA&#8221;). The process of obtaining FDA approval is often long and expensive. </font> <br /><br /><font style="FONT-FAMILY: ARIAL" size="1"><b>HEALTH CARE SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market. </font><br /><br /> <b><font style="FONT-FAMILY: ARIAL" size="1">EQUITY INVESTING RISK:</font></b><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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. </font><br /><br /> <b><font style="FONT-FAMILY: ARIAL" size="1">NON-DIVERSIFICATION RISK:</font></b><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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.

SPDR(R) S&P Insurance ETF
SPDR® S&P Insurance ETF
INVESTMENT OBJECTIVE
The SPDR S&P Insurance ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of publicly traded companies in the insurance industry.
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.

[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 at least October 31, 2013.
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:

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 62% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Insurance Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the insurance industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $2 billion with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $1 billion or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index. As of September 30, 2012, the Index was comprised of 44 stocks.

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.
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 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.
INSURANCE SECTOR RISK: The Fund’s assets will generally be concentrated in the insurance sector, which means the Fund will be more affected by the performance of the insurance sector versus a fund that was more diversified. Insurance companies’ profits are affected by many factors, including interest rate movements, the imposition of premium rate caps, competition and pressure to compete globally. Certain types of insurance companies may also be affected by weather catastrophes and other disasters and mortality rates. In addition, although the industry is currently subject to extensive regulation, companies in this industry may be adversely affected by increased governmental regulations or tax law changes in the future.
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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.
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.
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 following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at http://www.spdrs.com.
ANNUAL TOTAL RETURN (years ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 14.98%.
Highest Quarterly Return: 36.67% (Q3 2009)
Lowest Quarterly Return: -28.64% (Q4 2008)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective October 24, 2011, the Fund changed its benchmark index to the S&P Insurance Select Industry Index from the KBW Insurance Index. The Fund’s performance prior to October 24, 2011 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

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.
COMPUTER SOFTWARE/SERVICES SECTOR RISK:  The Fund’s assets will generally be concentrated in the computer industry, which means the Fund will be more affected by the performance of the computer industry versus a fund that was more diversified. The Fund will concentrate in segments of the computer industry. The computer industry, including companies servicing the computer industry, can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.
Many computer companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.
TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
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.
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 value of stocks of companies in the semiconductor industry and companies that rely heavily on technology is particularly vulnerable to rapid changes in product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Companies in the semiconductor industry and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the semiconductor industry may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
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.
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.
Risk Lose Money [Text] rr_RiskLoseMoney As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

Objective [Heading] rr_ObjectiveHeading INVESTMENT OBJECTIVE
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock
The SPDR S&P Food & Beverage ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the food and beverage segment of a U.S. total market composite index.
Expense [Heading] rr_ExpenseHeading FEES AND EXPENSES OF THE FUND
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”) other than brokerage commissions you may pay on purchases and sales of the Fund’s Shares.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading PORTFOLIO TURNOVER:
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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.
Other Expenses, New Fund, Based on Estimates [Text] rr_OtherExpensesNewFundBasedOnEstimates “Other Expenses” are based on estimated amounts for the current fiscal year.
Expense Example [Heading] rr_ExpenseExampleHeading EXAMPLE:
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:
Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the S&P Food & Beverage Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the food and beverage industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 61 stocks.

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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.
FOOD AND BEVERAGE SECTOR RISK:   The food and beverage industry is highly competitive and can be significantly affected by demographic and product trends, competitive pricing, food fads, marketing campaigns, environmental factors, government regulation, consumer preferences, nutritional and health concerns, federal, state and local food inspection and processing controls, consumer product liability claims, possible product tampering and the availability/expense of liability insurance. There are also risks associated with changing market prices as a result of, among other things, change in government support and trading policies, and agricultural conditions influencing the growth and harvest seasons.
CONSUMER STAPLES SECTOR RISK:   Consumer staples companies are subject to government regulation affecting their products which may negatively impact such companies’ performance. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food, beverage, household and personal products companies may be strongly affected by consumer interest, marketing campaigns and other factors affecting supply and demand.
RETAIL SECTOR RISK:   Retail and related industries can be significantly affected by the performance of the domestic and international economy, consumer confidence and spending, intense competition, changes in demographics, and changing consumer tastes and preferences.
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.
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.

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 91% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Mortgage Finance Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests in substantially all of the securities represented in the Index in approximately the same proportions as 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 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.
MORTGAGE SECTOR RISK: The Fund’s assets will generally be concentrated in the mortgage industry, which means the Fund will be more affected by the performance of the mortgage industry versus a fund that was more diversified. The mortgage industry can be significantly affected by regulatory changes, interest rate movements, home mortgage demand, refinancing activity, and residential delinquency trends. The residential real estate finance industry has changed rapidly over the last decade. Regulatory changes at banks and other federally insured institutions, in response to a high failure rate, have led to high capital ratios and more prudent underwriting. This reduced capacity has created growth opportunities for uninsured companies and secondary market products to fill unmet demand for home loans. Significant changes are occurring in the origination, packaging, marketing and selling, holding, and insuring of mortgage products.
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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.
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.
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 following bar chart and table provide an indication of the risks of investing in the Fund by showing the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at

ANNUAL TOTAL RETURN (year ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 26.75%.
Highest Quarterly Return: 19.45% (Q4 2011)
Lowest Quarterly Return: -26.77% (Q3 2011)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective October 24, 2011, the Fund has changed its benchmark index to the S&P Mortgage Finance Select Industry Index from the KBW Mortgage Finance Index. The Fund’s performance prior to October 24, 2011 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 47 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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.

Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for energy products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, securities of companies in the energy field are subject to swift price and supply fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Weak demand for the companies' products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the Fund's performance. Oil and gas equipment and services can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events and economic conditions.

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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>HOMEBUILDING SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;The Fund&#8217;s assets will generally be concentrated in the homebuilding industry, which means the Fund will be more affected by the performance of the homebuilding industry versus a fund that was more diversified. Companies within the Index can be significantly affected by the national, regional and local real estate markets. This industry is also sensitive to interest rate fluctuations which can cause changes in the availability of mortgage capital and directly affect the purchasing power of potential homebuyers. The building industry can be significantly affected by changes in government spending, consumer confidence, demographic patterns and the level of new and existing home sales. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDUSTRIAL SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;Stock prices for 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 stocks, 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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>CONSUMER DISCRETIONARY SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;The success of consumer product manufacturers and retailers is tied closely to the performance of the overall international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>RETAIL SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;Companies within the Index may include companies in the retail industry or companies that are closely tied to the retail industry.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false035false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse3false USDtruefalse$Duration_21Jun2012_20Jun2013C000027707_MemberS000010019_Memberhttp://www.sec.gov/CIK0001064642duration2012-06-21T00:00:002013-06-20T00:00:00falsefalseSPDR(R) S&P(R) Homebuilders ETFdei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldisst2_S000010019Memberdei_LegalEntityAxisexplicitMemberfalsefalseSPDR(R) S&P(R) Homebuilders ETFrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldisst2_C000027707Memberrr_ProspectusShareClassAxisexplicitMemberpureStandardhttp://www.xbrl.org/2003/instancepure0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse036true 2rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse037false 3rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1truetruetrue0.00350.0035falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false038false 3rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1truetruetrue00[1]falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

Objective [Heading] rr_ObjectiveHeading INVESTMENT OBJECTIVE
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock
The SPDR S&P Aerospace & Defense ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the aerospace and defense segment of a U.S. total market composite index.
Expense [Heading] rr_ExpenseHeading FEES AND EXPENSES OF THE FUND
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock 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.
Operating Expenses Caption [Text] rr_OperatingExpensesCaption ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading PORTFOLIO TURNOVER:
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 period from the commencement of the Fund’s operations (September 28, 2011) to the end of the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 23.00%
Expense Example [Heading] rr_ExpenseExampleHeading EXAMPLE:
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:
Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the S&P Aerospace & Defense Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the aerospace and defense industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 37 stocks.

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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.

AEROSPACE AND DEFENSE SECTOR RISK:  The Fund’s assets will generally be concentrated in the aerospace and defense industry, which means the Fund will be more affected by the performance of the aerospace and defense industry versus a fund that was more diversified. The aerospace and defense industry can be significantly affected by government aerospace and defense regulation and spending policies because companies involved in this industry rely to a significant extent on U.S. (and other) 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.

INDUSTRIAL SECTOR RISK:  Stock prices for 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 stocks, 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.

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.

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.
Risk Lose Money [Text] rr_RiskLoseMoney As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

THE FUND’S PRINCIPAL INVESTMENT STRATEGY

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 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.
COMPUTER SOFTWARE/SERVICES SECTOR RISK:  The Fund’s assets will generally be concentrated in the computer industry, which means the Fund will be more affected by the performance of the computer industry versus a fund that was more diversified. The Fund will concentrate in segments of the computer industry. The computer industry, including companies servicing the computer industry, can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products and the ability to service such products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.
Many computer companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.
TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
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.
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 Index represents the outsourcing and information technology consulting industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 48 stocks.

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.
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 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.

OUTSOURCING AND CONSULTING SECTOR RISK:  The Fund’s assets will generally be concentrated in the outsourcing and information technology consulting industry, which means the Fund will be more affected by the performance of the outsourcing and information technology consulting industry versus a fund that was more diversified. The information technology consulting services and outsourcing industry can be significantly affected by competitive pressures, such as technological developments, fixed-rate pricing, and the ability to attract and retain skilled employees. The success of companies in this industry is subject to continued demand for business services.

COMPUTER SECTOR RISK:  The Fund will concentrate in segments of the computer industry. The computer industry can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

Many computer companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

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.

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.

Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the S&P LeisureTime Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

LEISURE SECTOR RISK:  The Fund’s assets will generally be concentrated in the leisure industry, which means the Fund will be more affected by the performance of the leisure industry versus a fund that was more diversified. The leisure industry can be significantly affected by the performance of the overall economy, changing consumer tastes, intense competition, technological developments, and government regulation.

CONSUMER DISCRETIONARY SECTOR RISK:  The success of consumer product manufacturers and retailers is tied closely to the performance of the overall international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

RETAIL SECTOR RISK:  Retail and related industries can be significantly affected by the performance of the domestic and international economy, consumer confidence and spending, intense competition, changes in demographics, and changing consumer tastes and preferences.

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.

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.

Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the Wells Fargo Hybrid and Preferred Securities Aggregate Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is a modified market capitalization weighted index designed to measure the performance of non-convertible preferred stock and securities that are functionally equivalent to preferred stock, including, but not limited to, depositary preferred securities, perpetual subordinated debt and certain securities issued by banks and other financial institutions that are eligible for capital treatment with respect to such instruments akin to that received for issuance of straight preferred stock (collectively, “Preferred Securities”). Preferred Securities generally pay fixed rate distributions and typically have “preference” over common stock in the payment of distributions and the liquidation of a company’s assets — preference means that a company must pay distributions on its Preferred Securities before paying dividends on its common stock, and the claims of Preferred Securities holders are ahead of common stockholders’ claims on assets in a corporate liquidation. The Index includes Preferred Securities that meet the following criteria: (i) are non-convertible; (ii) have a par amount of $25; (iii) are listed on the New York Stock Exchange or NYSE Arca, Inc. (“NYSE Arca”); (iv) maintain a minimum par value of $250 million; (v) are U.S. dollar denominated; (vi) are rated investment grade by one of Moody’s Investors Service, Inc. or Standard & Poor’s Ratings Services; (vii) are publicly registered or exempt from registration under the Securities Act of 1933; and (viii) have a minimum monthly trading volume during each of the last six months of at least 250,000 trading units. The Index does not include auction rate preferred securities, convertible preferred shares, securities subject to sinking fund provisions, shares in closed-end funds, municipal securities, or repackaged securities linked to a security, a basket of securities or an index. The Index is rebalanced monthly, on the final NYSE Arca trading day of each month. Issuers of Preferred Securities may be either U.S. based or foreign. As of September 30, 2012, the Index was comprised of 134 Preferred Securities.

The Index is sponsored by Wells Fargo & Company (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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.
PREFERRED SECURITIES RISK:  There are special risks associated with investing in Preferred Securities. Generally, Preferred Security holders (such as the Fund) have no voting rights with respect to the issuing company unless certain events occur. In addition, Preferred Securities are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. Unlike debt securities, dividend payments on a Preferred Security typically must be declared by the issuer’s board of directors. An issuer’s board of directors is generally not under any obligation to pay a dividend (even if such dividends have accrued), and may suspend payment of dividends on Preferred Securities at any time. In the event an issuer of Preferred Securities experiences economic difficulties, the issuer’s Preferred Securities may lose substantial value due to the reduced likelihood that the issuer’s board of directors will declare a dividend and the fact that the Preferred Security may be subordinated to other securities of the same issuer. There is a chance that the issuer of any of the Fund’s holdings will default (fail to make scheduled dividend payments on the Preferred Security or scheduled interest payments on other obligations of the issuer not held by the Fund).
INTEREST RATE RISK:  Because many Preferred Securities pay dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the Preferred Securities held by the Fund are likely to decline. To the extent that the Fund invests a substantial portion of its assets in fixed rate Preferred Securities, rising interest rates may cause the value of the Fund’s investments to decline significantly.
ISSUER RISK:  Because many Preferred Securities allow holders to convert the Preferred Securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer’s common stock and, therefore, declining common stock values may also cause the value of the Fund’s investments to decline.
CALL RISK:  Preferred Securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a Preferred Security having a higher than average yield may cause a decrease in the Fund’s yield.
FINANCIAL SECTOR RISK:  Preferred Securities may be issued by financial institutions. Financial institutions 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 caused certain financial institutions to incur large losses. Numerous financial institutions 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 institutions 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.
FOREIGN SECURITIES 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. These risks may be heightened in connection with investments in developing or emerging countries.
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.
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.

Risk/Return [Heading] rr_RiskReturnHeading SPDR® Global Dow ETF
Objective [Heading] rr_ObjectiveHeading INVESTMENT OBJECTIVE
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock
The SPDR Global Dow ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of multinational blue-chip issuers.
Expense [Heading] rr_ExpenseHeading FEES AND EXPENSES OF THE FUND
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock 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.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading PORTFOLIO TURNOVER:
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 11% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 11.00%
Expense Example [Heading] rr_ExpenseExampleHeading EXAMPLE:
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:
Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of The Global Dow (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is made up of 150 constituents from around the world selected by an Averages Committee comprised of the managing editor of the Wall Street Journal, the head of Dow Jones Indexes research and the head of CME Group research. The 150 companies are selected not just based on size and reputation, but also on their promise of future growth. The Index has been designed to cover both developed and emerging countries. The Index is equal weighted and will be reset to equal weights annually each September. As of September 30, 2012, the Index was comprised of 150 stocks.

The Index is sponsored by S&P Dow Jones Indices LLC (“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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.

FOREIGN SECURITIES 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. 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.

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.

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 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 SSgA Funds Management, Inc. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), the investment adviser to the Fund). </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is designed to provide a measure of real estate securities that serve as proxies for direct real estate investing, in part by excluding securities whose value is not always closely tied to the value of the underlying real estate. The reason for the exclusions is that factors other than real estate supply and demand, such as interest rates, influence the market value of these companies. The Index is a market capitalization weighted index of publicly traded real estate investment trusts (&#8220;REITs&#8221;) and is comprised of companies whose charters are the equity ownership and operation of commercial real estate and which operate under the REIT Act of 1960. To be included in the Index, a company must be both an equity owner and operator of commercial and/or residential real estate. Businesses excluded from the Index include: mortgage REITs, net-lease REITs, real estate finance companies, mortgage brokers and bankers, commercial and residential real estate brokers and real estate agents, home builders, large landowners and subdividers of unimproved land, hybrid REITs, and timber REITs, as well as companies that have more than 25% of their assets in direct mortgage investments. A company must have a minimum total market capitalization of at least $200 million at the time of its inclusion, and at least 75% of the company&#8217;s total revenue must be derived from the ownership and operation of real estate assets. The liquidity of the company&#8217;s stock must be commensurate with that of other institutionally held real estate securities. The Index is generally rebalanced quarterly, and returns are calculated on a buy and hold basis except as necessary to reflect the occasional occurrence of Index changes in the middle of the month. Each REIT in the Index is weighted by its float-adjusted market capitalization. That is, each security is weighted to reflect the attainable market performance of the security which reflects that portion of securities shares that are accessible to investors. The Index is priced daily and is a total return (price and income) benchmark. As of September 30, 2012, the Index was comprised of 85 REITs. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund, the Adviser or the Sub-Adviser (as defined below). 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. </font>falsefalsefalsenonnum:textBlockItemTypenaPrincipal investment strategies of the Fund.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;While the Sub-Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>REAL ESTATE SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;The Fund will concentrate its investments in the real estate sector. Adverse economic, business or political developments affecting real estate could have a major effect on the value of the Fund&#8217;s investments. Investing in real estate securities (which include REITs) may subject the Fund to risks associated with the direct ownership of real estate, such as decreases in real estate values, overbuilding, increased competition and other risks related to local or general economic conditions, increases in operating costs and property taxes, changes in zoning laws, casualty or condemnation losses, possible environmental liabilities, regulatory limitations on rent and fluctuations in rental income. Changes in interest rates may also affect the value of the Fund&#8217;s investment in real estate securities. Certain real estate securities have a relatively small market capitalization, which may tend to increase the volatility of the market price of these securities. Real estate securities are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Real estate securities are also subject to heavy cash flow dependency and defaults by borrowers. In addition, a REIT could fail to qualify for favorable tax treatment under the Internal Revenue Code of 1986, as amended and could fail to maintain exemption from the registration requirements of the Investment Company Act of 1940, as amended. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

SPDR(R) S&P 600 Small Cap Value ETF
SPDR® S&P 600 Small Cap Value ETF
INVESTMENT OBJECTIVE
The SPDR S&P 600 Small Cap Value ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of small capitalization exchange traded U.S. equity securities exhibiting “value” characteristics.
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”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. 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) S&P 600 Small Cap Value ETF
MANAGEMENT FEES 0.25%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
ACQUIRED FUND FEES AND EXPENSES [2] 0.06%
TOTAL ANNUAL FUND OPERATING EXPENSES [2] 0.31%
[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 at least October 31, 2013.
[2] "Acquired Fund Fees and Expenses" are not included in the Fund's financial statements, which provide a clearer picture of a fund's actual operating costs.
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:

YEAR 3
YEAR 5

32 100 174 393
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 34% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P SmallCap 600 Value Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index measures the performance of the small-capitalization value sector in the U.S. equity market. The Index consists of those stocks, including BDCs, in the S&P SmallCap 600 Index exhibiting the strongest value characteristics based on: (i) book value to price ratio; (ii) earnings to price ratio; and (iii) sales to price ratio. The selection universe for the S&P SmallCap 600 Index includes all U.S. common equities listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally between $300 million and $1.4 billion at the time of inclusion. Capitalization ranges may be revised by the Index Provider (as defined below) at any time. To be included in the Index, a security should (i) have an annual dollar value traded to float adjusted market capitalization ratio of 1 or greater; (ii) trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; (iii) have a public float of at least 50%; and (iv) have four consecutive quarters of positive as-reported earnings. The Index is market capitalization weighted and rebalanced annually on the third Friday of December. As of September 30, 2012, the Index was comprised of 455 stocks.

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.
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 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.
SMALL CAP RISK:  Small-sized companies may be more volatile and more likely than large- and mid-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of small companies could trail the returns on investments in stocks of larger companies.
VALUE RISK:  The Fund employs a “value” style of investing that emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on “value” equity securities are less than returns on other styles of investing or the overall stock market.
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.
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 following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at http://www.spdrs.com.
ANNUAL TOTAL RETURN (years ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 14.43%.
Highest Quarterly Return: 25.67% (Q3 2009)
Lowest Quarterly Return: -25.28% (Q4 2008)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Prior to December 17, 2010, the Fund’s investment strategy sought to track the total return performance of an index different from the S&P SmallCap 600 Value Index. Performance of the Fund prior to December 17, 2010 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance.

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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $1 billion with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $600 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $500 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index. As of September 30, 2012, the Index was comprised of 45 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>MORTGAGE SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> The Fund&#8217;s assets will generally be concentrated in the mortgage industry, which means the Fund will be more affected by the performance of the mortgage industry versus a fund that was more diversified. The mortgage industry can be significantly affected by regulatory changes, interest rate movements, home mortgage demand, refinancing activity, and residential delinquency trends. The residential real estate finance industry has changed rapidly over the last decade. Regulatory changes at banks and other federally insured institutions, in response to a high failure rate, have led to high capital ratios and more prudent underwriting. This reduced capacity has created growth opportunities for uninsured companies and secondary market products to fill unmet demand for home loans. Significant changes are occurring in the origination, packaging, marketing and selling, holding, and insuring of mortgage products.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>FINANCIAL SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph 2 -Subparagraph iv false036false 0truefalsetruefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalse3false USDtruefalse$Duration_21Jun2012_20Jun2013C000033542_MemberS000012326_Memberhttp://www.sec.gov/CIK0001064642duration2012-06-21T00:00:002013-06-20T00:00:00falsefalseSPDR(R) S&P Mortgage Finance(SM) ETFdei_LegalEntityAxisxbrldihttp://xbrl.org/2006/xbrldisst2_S000012326Memberdei_LegalEntityAxisexplicitMemberfalsefalseSPDR(R) S&P Mortgage Finance(SM) ETFrr_ProspectusShareClassAxisxbrldihttp://xbrl.org/2006/xbrldisst2_C000033542Memberrr_ProspectusShareClassAxisexplicitMemberpureStandardhttp://www.xbrl.org/2003/instancepure0USDStandardhttp://www.xbrl.org/2003/iso4217USDiso42170USDUSD$nanafalse037true 2rr_RiskReturnAbstractrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00falsefalsefalsexbrli:stringItemTypestringfalse038false 3rr_ManagementFeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1truetruetrue0.00350.0035falsefalsefalserr:NonNegativePure4TypepureManagement Fees include investment advisory fees (including any fees based on the Fund's performance), any other management fees payable to the investment adviser or its affiliates, and administrative fees payable to the investment adviser or its affiliates that are not included as "Other Expenses."Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 3 -Subparagraph a false039false 3rr_DistributionAndService12b1FeesOverAssetsrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseverboseLabel1truetruetrue00[1]falsefalsefalserr:NonNegativePure4TypepureDistribution [and/or Service] (12b-1) Fees" include all distribution or other expenses incurred during the most recent fiscal year under a plan adopted pursuant to rule 12b-1 [17 CFR 270.12b-1].

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 SSgA Funds Management, Inc. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), the investment adviser to the Fund). </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="2">The Index represents the banks industry group of the S&amp;P Total Market Index (&#8220;S&amp;P TMI&#8221;). The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $2 billion with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 100%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $1 biillion or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index. As of September 30, 2012, the Index was comprised of 41 stocks. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>BANKING SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;The Fund&#8217;s assets will generally be concentrated in the banking sector, which means the Fund will be more affected by the performance of the banking sector versus a fund that was more diversified. The performance of bank stocks may be affected by 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 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. Credit losses resulting from financial difficulties of borrowers can negatively impact the sector. Banks may also be subject to severe price competition. The regional banking industry is highly competitive and failure to maintain or increase market share may result in lost market share.</font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>FINANCIAL SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities.</font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective October 24, 2011, the Fund changed its benchmark index to the S&amp;P Banks Select Industry Index from the KBW Bank Index.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's performance with a broad measure of market performance).Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 4 -Subsection b -Paragraph

Shareholder Fees (fees paid directly from your investment) 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 you redeem all of your shares at the end of those periods.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less. The following Instructions apply to New Funds.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Form -Number N-1A -Chapter A -Section 3 -Subsection instructions -Paragraph 1 -Subparagraph d false06false 3rr_ExpenseNarrativeTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00<font style="FONT-FAMILY: ARIAL" size="2">This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (&#8220;Shares&#8221;). &#8220;Acquired Fund Fees and Expenses&#8221; reflect the Fund&#8217;s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (&#8220;BDCs&#8221;). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund&#8217;s net asset value. They have no impact on the costs associated with fund operations.

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 SSgA Funds Management, Inc. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), the investment adviser to the Fund). </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="2">The Index measures the performance of the small-capitalization sector in the U.S. equity market. The selection universe for the Index includes all U.S. common equities, including BDCs, listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally between $300 million and $1.4 billion at the time of inclusion. Capitalization ranges may be revised by the Index Provider (as defined below) at any time. To be included in the Index, a security should (i) have an annual dollar value traded to float adjusted market capitalization ratio of 1 or greater; (ii) trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; (iii) have a public float of at least 50%; and (iv) have four consecutive quarters of positive as-reported earnings. The Index is float-adjusted, market capitalization weighted and changes to the Index are made on an as-needed basis. As of September 30, 2012, the Index was comprised of 603 stocks. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>SMALL CAP RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;Small-sized companies may be more volatile and more likely than large- and mid-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of small companies could trail the returns on investments in stocks of larger companies. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b> </font><font style="FONT-FAMILY: ARIAL" size="2"> &nbsp;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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares.

All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement.

A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b> </font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2"> While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>MID CAP RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2"> Mid-sized companies may be more volatile and more likely than large-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of mid-size companies could trail the returns on investments in stocks of larger or smaller companies. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>GROWTH RISK:</b>&nbsp;&nbsp; </font><font style="FONT-FAMILY: ARIAL" size="2"> The Fund emphasizes a &#8220;growth&#8221; style of investing. The market values of growth stocks may be more volatile than other types of investments. The prices of growth stocks tend to reflect future expectations, and when those expectations change or are not met, share prices generally fall. The returns on &#8220;growth&#8221; securities may or may not move in tandem with the returns on other styles of investing or the overall stock market. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2"> 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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2"> 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.

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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares.

A Money Market Fund should show only the returns described in clause (A) of the preceding sentence. All returns should be shown for 1-, 5-, and 10- calendar year periods ending on the date of the most recently completed calendar year (or for the life of the Fund, if shorter), but only for periods subsequent to the effective date of the Fund's registration statement. The table also should show the returns of an appropriate broad-based securities market index as defined in Instruction 5 to Item 22(b)(7) for the same periods. A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield. For a Fund (other than a Money Market Fund or a Fund described in General Instruction C.3.(d)(iii)), provide the information in the following table with the specified captions AVERAGE ANNUAL TOTAL RETURNS (For the periods ended December 31, _____). For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's

SPDR(R) S&P Capital Markets ETF
SPDR® S&P Capital Markets ETF
INVESTMENT OBJECTIVE
The SPDR S&P Capital Markets ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of publicly traded companies that do business as broker-dealers, asset managers, trust and custody banks or exchanges.
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”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. 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) S&P Capital Markets ETF
MANAGEMENT FEES 0.35%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES [2] none
ACQUIRED FUND FEES AND EXPENSES [3] 0.91%
TOTAL ANNUAL FUND OPERATING EXPENSES [2][3] 1.26%
[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 at least October 31, 2013.
[2] Amounts do not reflect certain other expenses of 0.01% incurred during the prior fiscal year which are not expected to be incurred during the current fiscal year.
[3] "Acquired Fund Fees and Expenses" are not included in the Fund's financial statements, which provide a clearer picture of a fund's actual operating costs.
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 3
YEAR 5

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 64% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Capital Markets Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the capital markets industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents, including BDCs, belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index. As of September 30, 2012, the Index was comprised of 45 stocks.

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.
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 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.
CAPITAL MARKETS SECTOR RISK:  The Fund’s assets will generally be concentrated in the capital markets sector, which means the Fund will be more affected by the performance of the capital markets sector versus a fund that was more diversified. Companies within the Index can be significantly affected by stock and bank trading activity, changes in governmental regulation, continuing increases in price competition, decreases in fees or fee-related business, including investment banking, brokerage, asset management and other servicing fees, fluctuation in interest rates and other factors which could adversely affect financial markets.
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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.
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.
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.
BDC INVESTING RISK:  BDCs, by their nature, invest in and provide services to privately held and thinly traded companies, which involve greater risk than well established, publicly-traded companies. Further, because BDCs are regulated as investment companies, there are regulatory constraints on both the BDC’s operations, which could negatively impact the performance of the BDC, and on a fund’s ability to invest in BDCs, which could increase the risk of tracking error.
FUND PERFORMANCE
The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at

ANNUAL TOTAL RETURN (years ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 18.00%.
Highest Quarterly Return: 29.06% (Q2 2009)
Lowest Quarterly Return: -33.43% (Q4 2008)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective October 24, 2011, the Fund changed its benchmark index to the S&P Capital Markets Select Industry Index from the KBW Capital Markets Index. The Fund’s performance prior to October 24, 2011 is therefore based on the Fund’s prior investment strategy to track a different benchmark 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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $1 billion with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $600 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $500 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>MORTGAGE SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> The Fund&#8217;s assets will generally be concentrated in the mortgage industry, which means the Fund will be more affected by the performance of the mortgage industry versus a fund that was more diversified. The mortgage industry can be significantly affected by regulatory changes, interest rate movements, home mortgage demand, refinancing activity, and residential delinquency trends. The residential real estate finance industry has changed rapidly over the last decade. Regulatory changes at banks and other federally insured institutions, in response to a high failure rate, have led to high capital ratios and more prudent underwriting. This reduced capacity has created growth opportunities for uninsured companies and secondary market products to fill unmet demand for home loans. Significant changes are occurring in the origination, packaging, marketing and selling, holding, and insuring of mortgage products.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>FINANCIAL SECTOR RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2"> 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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock
The SPDR S&P Retail ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the retail segment of a U.S. total market composite index.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 39% of the average value of its portfolio.

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.

Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the S&P Retail Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the retail industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 96 stocks.

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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.
RETAIL SECTOR RISK:  The Fund’s assets will generally be concentrated in the retail industry, which means the Fund will be more affected by the performance of the retail industry versus a fund that was more diversified. Retail and related industries can be significantly affected by the performance of the domestic and international economy, consumer confidence and spending, intense competition, changes in demographics, and changing consumer tastes and preferences.
CONSUMER STAPLES SECTOR RISK:  Consumer staples companies are subject to government regulation affecting their products which may negatively impact such companies’ performance. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food, beverage, household and personal products companies may be strongly affected by consumer interest, marketing campaigns and other factors affecting supply and demand.
CONSUMER DISCRETIONARY SECTOR RISK:  The success of consumer product manufacturers and retailers is tied closely to the performance of the overall international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.
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.
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.
Risk Lose Money [Text] rr_RiskLoseMoney As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

SPDR® S&P 400 Mid Cap Value ETF
INVESTMENT OBJECTIVE
The SPDR S&P 400 Mid Cap Value ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of medium capitalization exchange traded U.S. equity securities exhibiting “value” characteristics.
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”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. 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) S&P 400 Mid Cap Value ETF
MANAGEMENT FEES 0.25%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
ACQUIRED FUND FEES AND EXPENSES [2] 0.03%
TOTAL ANNUAL FUND OPERATING EXPENSES [2] 0.28%
[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 at least October 31, 2013.
[2] "Acquired Fund Fees and Expenses" are not included in the Fund's financial statements, which provide a clearer picture of a fund's actual operating costs.
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:

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 28% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P MidCap 400 Value Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index measures the performance of the mid-capitalization value sector in the U.S. equity market. The Index consists of those stocks, including BDCs, in the S&P MidCap 400 Index exhibiting the strongest value characteristics based on: (i) book value to price ratio; (ii) earnings to price ratio; and (iii) sales to price ratio. The selection universe for the S&P MidCap 400 Index includes all U.S. common equities listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally between $1 billion and $4.4 billion at the time of inclusion. Capitalization ranges may be revised by the Index Provider (as defined below) at any time. To be included in the Index, a security should (i) have an annual dollar value traded to float adjusted market capitalization ratio of 1 or greater; (ii) trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; (iii) have a public float of at least 50%; and (iv) have four consecutive quarters of positive as-reported earnings. The Index is market capitalization weighted and rebalanced annually on the third Friday of December. As of September 30, 2012, the Index was comprised of 300 stocks.

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.
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 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.
MID CAP RISK:   Mid-sized companies may be more volatile and more likely than large-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of mid-size companies could trail the returns on investments in stocks of larger or smaller companies.
VALUE RISK:   The Fund employs a “value” style of investing that emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on “value” equity securities are less than returns on other styles of investing or the overall stock market.
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.
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

Highest Quarterly Return: 23.46% (Q3 2009)
Lowest Quarterly Return: -24.41% (Q4 2008)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Prior to December 17, 2010, the Fund’s investment strategy sought to track the total return performance of an index different from the S&P MidCap 400 Value Index. Performance of the Fund prior to December 17, 2010 is therefore based on the Fund’s prior investment strategy to track a different benchmark index.

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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the outsourcing and information technology consulting industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 48 stocks.

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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.

OUTSOURCING AND CONSULTING SECTOR RISK:  The Fund’s assets will generally be concentrated in the outsourcing and information technology consulting industry, which means the Fund will be more affected by the performance of the outsourcing and information technology consulting industry versus a fund that was more diversified. The information technology consulting services and outsourcing industry can be significantly affected by competitive pressures, such as technological developments, fixed-rate pricing, and the ability to attract and retain skilled employees. The success of companies in this industry is subject to continued demand for business services.

COMPUTER SECTOR RISK:  The Fund will concentrate in segments of the computer industry. The computer industry can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products produced by computer companies is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer’s products or in the market for products based on a particular technology could have a material adverse effect on a participant’s operating results.

Many computer companies rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by computer companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology.

TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.

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.

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.

SPDR® Dow Jones Mid Cap ETF
INVESTMENT OBJECTIVE
The SPDR Dow Jones Mid Cap ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of mid-capitalization exchange traded U.S. equity securities.
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.

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:

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 20% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the Dow Jones U.S. Mid-Cap Total Stock Market Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is a float-adjusted market capitalization weighted index that represents the mid-cap portion of the Dow Jones U.S. Total Stock Market Index (“Total Stock Market Index”). The Total Stock Market Index tracks all the U.S. common stocks regularly traded on the New York Stock Exchange, NYSE Amex and the NASDAQ Stock Market. The Index includes the components of the Total Stock Market Index ranked 501-1,000 by full market capitalization. The composition of the Index is assigned based on the semiannual review of the Total Stock Market Index. New issues are added to the Index on a monthly basis as new issues are added to the Total Stock Market Index and fall within the mid cap portion. An issue is removed as soon as prudently possible if it fails to meet the inclusion requirement of the Total Stock Market Index. Shares and float factors of the Index are updated on a quarterly basis. As of September 30, 2012, the Index was comprised of 502 stocks.

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.
PRINCIPAL RISKS OF INVESTING IN THE FUND

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.

MID CAP RISK:  Mid-sized companies may be more volatile and more likely than large-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of mid-size companies could trail the returns on investments in stocks of larger or smaller companies.

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.

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.

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 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.
FOOD AND BEVERAGE SECTOR RISK:   The food and beverage industry is highly competitive and can be significantly affected by demographic and product trends, competitive pricing, food fads, marketing campaigns, environmental factors, government regulation, consumer preferences, nutritional and health concerns, federal, state and local food inspection and processing controls, consumer product liability claims, possible product tampering and the availability/expense of liability insurance. There are also risks associated with changing market prices as a result of, among other things, change in government support and trading policies, and agricultural conditions influencing the growth and harvest seasons.
CONSUMER STAPLES SECTOR RISK:   Consumer staples companies are subject to government regulation affecting their products which may negatively impact such companies’ performance. For instance, government regulations may affect the permissibility of using various food additives and production methods of companies that make food products, which could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food, beverage, household and personal products companies may be strongly affected by consumer interest, marketing campaigns and other factors affecting supply and demand.
RETAIL SECTOR RISK:   Retail and related industries can be significantly affected by the performance of the domestic and international economy, consumer confidence and spending, intense competition, changes in demographics, and changing consumer tastes and preferences.
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.
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 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 SSgA Funds Management, Inc.

The Index is one of twenty-five (25) of the S&amp;P Select Industry Indices (the &#8220;Select Industry Indices&#8221;), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (&#8220;GICS&#8221;). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&amp;P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% <i>or </i>have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&amp;P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 47 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>OIL AND GAS SECTOR RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The Fund's assets will generally be concentrated in the oil and gas equipment and services industry, which means the Fund will be more affected by the performance of the oil and gas equipment and services industry versus a fund that was more diversified. Companies in the oil and gas sector develop and produce crude oil and natural gas and provide drilling and other energy resources production and distribution related services. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for energy products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, securities of companies in the energy field are subject to swift price and supply fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Weak demand for the companies' products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the Fund's performance. Oil and gas equipment and services can be significantly affected by natural disasters as well as changes in exchange rates, interest rates, government regulation, world events and economic conditions. These companies may be at risk for environmental damage claims.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>ENERGY SECTOR RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2"> Energy companies develop and produce oil, gas and consumable fuels and provide drilling and other energy resources production and distribution related services.

Weak demand for energy companies' products or services or for energy products and services in general, as well as negative developments in these other areas, including natural disasters or terrorist attacks, would adversely impact the Fund's performance.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.

SPDR(R) S&P(R) Transportation ETF
SPDR® S&P® Transportation ETF
INVESTMENT OBJECTIVE
The SPDR S&P Transportation ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the transportation segment of a U.S. total market composite index.
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) S&P(R) Transportation ETF
MANAGEMENT FEES 0.35%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
TOTAL ANNUAL FUND OPERATING EXPENSES 0.35%
[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 at least October 31, 2013.
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
YEAR 5
YEAR 10
SPDR(R) S&P(R) Transportation ETF
36 113 197 443
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 25% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Transportation Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the transportation industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 39 stocks.

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.
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 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.

TRANSPORTATION SECTOR RISK:  The Fund’s assets will generally be concentrated in the transportation industry, which means the Fund will be more affected by the performance of the transportation industry versus a fund that was more diversified. The transportation industry can be significantly affected by changes in the economy, fuel prices, labor relations, technology developments, exchange rates, insurance costs, industry competition and government regulation.

INDUSTRIAL SECTOR RISK:  Stock prices for 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 stocks, 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.

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.

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.

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 36% of the average value of its portfolio.

In seeking to track the performance of the S&P Semiconductor Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the semiconductors industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 47 stocks.

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.
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 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.
SEMICONDUCTOR SECTOR RISK:  The Fund’s assets will generally be concentrated in the semiconductor industry, which means the Fund will be more affected by the performance of the semiconductor industry versus a fund that was more diversified. The Fund is subject to the risk that market or economic factors impacting companies in the semiconductor industry and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of companies in the semiconductor industry and companies that rely heavily on technology is particularly vulnerable to rapid changes in product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Companies in the semiconductor industry and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the semiconductor industry may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
TECHNOLOGY SECTOR RISK:  The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel.
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.
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 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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares.

If these sales charges (loads) were included, your costs would be higher. 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 may indicate higher transaction costs. 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 whole portfolio. Instructions. A.3.instructions.6 New Funds. For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

The Index consists of those stocks, including BDCs, in the S&amp;P SmallCap 600 Index exhibiting the strongest value characteristics based on: (i) book value to price ratio; (ii) earnings to price ratio; and (iii) sales to price ratio. The selection universe for the S&amp;P SmallCap 600 Index includes all U.S. common equities listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally between $300 million and $1.4 billion at the time of inclusion. Capitalization ranges may be revised by the Index Provider (as defined below) at any time. To be included in the Index, a security should (i) have an annual dollar value traded to float adjusted market capitalization ratio of 1 or greater; (ii) trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; (iii) have a public float of at least 50%; and (iv) have four consecutive quarters of positive as-reported earnings.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>SMALL CAP RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">Small-sized companies may be more volatile and more likely than large- and mid-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of small companies could trail the returns on investments in stocks of larger companies. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>VALUE RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The Fund employs a &#8220;value&#8221; style of investing that emphasizes undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on &#8220;value&#8221; equity securities are less than returns on other styles of investing or the overall stock market. </font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

A Fund that has been in existence for more than 10 years also may include returns for the life of the Fund. A Money Market Fund may provide the Fund's 7-day yield ending on the date of the most recent calendar year or disclose a toll-free (or collect) telephone number that investors can use to obtain the Fund's current 7-day yield.

For a Fund that provides annual total returns for only one calendar year or for a Fund that does not include the bar chart because it does not have annual returns for a full calendar year, modify, as appropriate, the narrative explanation required by paragraph (c)(2)(i) (e.g., by stating that the information gives some indication of the risks of an investment in the Fund by comparing the Fund's

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 SSgA Funds Management, Inc.

The Index was the first listed broad-market technology barometer dedicated exclusively to the electronics-based technology industry. The Index comprises companies drawn from the following technology sub-sectors: computer services; design software; server software, PC software and new media; networking and telecom equipment; server hardware, PC hardware and peripherals; specialized systems; and semiconductors. The New York Stock Exchange (&#8220;NYSE&#8221;) calculates the Index. Morgan Stanley &amp; Co. Incorporated acts as consultant to the NYSE in connection with NYSE&#8217;s maintenance of the Index. The Index is equal-dollar-weighted to ensure that each of its component securities is represented in approximate equal dollar value. To ensure that each component stock continues to represent approximate equal market value in the Index, adjustments, if necessary, are made annually after the close of trading on the third Friday of December. As of September 30, 2012, the Index was comprised of 35 stocks. </font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by Morgan Stanley &amp; Co.

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&#8217;s return to be lower than if the Fund employed an active strategy. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">While the Adviser seeks to track the performance of the Index as closely as possible (<i>i.e., </i>achieve a high degree of correlation with the Index), the Fund&#8217;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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>TECHNOLOGY SECTOR RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The Fund&#8217;s assets will generally be concentrated in the technology industry, which means the Fund will be more affected by the performance of the technology industry versus a fund that was more diversified. The Fund is subject to the risk that market or economic factors impacting technology companies and companies that rely heavily on technology advances could have a major effect on the value of the Fund&#8217;s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Additionally, companies in the technology sector may face dramatic and often unpredictable changes in growth rates and competition for the services of qualified personnel. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>ELECTRONICS INDUSTRY RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">The electronics industry can be significantly affected by competitive pressures, aggressive pricing, technological developments, changing domestic demand, the ability to attract and retain skilled employees and availability and price of components. The market for products is characterized by rapidly changing technology, rapid product obsolescence, cyclical market patterns, evolving industry standards and frequent new product introductions. The success of industry participants depends in substantial part on the timely and successful introduction of new products. An unexpected change in one or more of the technologies affecting an issuer&#8217;s products or in the market for products based on a particular technology could have a material adverse effect on a participant&#8217;s operating results. Companies in the electronics industry may rely on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by such companies to protect their proprietary rights will be adequate to prevent misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies&#8217; technology. </font> <br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>EQUITY INVESTING RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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. </font><br/><br/> <font style="FONT-FAMILY: ARIAL" size="1"><b>NON-DIVERSIFICATION RISK:</b></font>&nbsp;&nbsp;<font style="FONT-FAMILY: ARIAL" size="2">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&#8217;s performance may be disproportionately impacted by the performance of relatively few securities. </font></blockquote></blockquote>falsefalsefalsenonnum:textBlockItemTypenaNarrative Risk Disclosure.

SPDR(R) S&P Regional Banking(SM) ETF
SPDR® S&P Regional Banking ETF
INVESTMENT OBJECTIVE
The SPDR S&P Regional Banking ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the regional banking segment of the U.S. banking industry.
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) S&P Regional Banking(SM) ETF
MANAGEMENT FEES 0.35%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
TOTAL ANNUAL FUND OPERATING EXPENSES 0.35%
[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 at least October 31, 2013.
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:

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 44% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Regional Banks Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the regional banks industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is a modified equal weighted index. As of September 30, 2012, the Index was comprised of 76 stocks.

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.
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 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.
BANKING SECTOR RISK:  The Fund’s assets will generally be concentrated in the banking sector, which means the Fund will be more affected by the performance of the banking sector versus a fund that was more diversified. The performance of bank stocks may be affected by 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 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. Credit losses resulting from financial difficulties of borrowers can negatively impact the sector. Banks may also be subject to severe price competition. The regional banking industry is highly competitive and failure to maintain or increase market share may result in lost market share.
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, 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. Adverse economic, business or political developments affecting real estate could have a major effect on the value of real estate securities (which include REITS). Declining real estate values 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.
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.
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 following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at http://www.spdrs.com.
ANNUAL TOTAL RETURN (years ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 18.72%.
Highest Quarterly Return: 34.92% (Q3 2008)
Lowest Quarterly Return: -33.24% (Q1 2009)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective October 24, 2011, the Fund changed its benchmark index to the S&P Regional Banks Select Industry Index from the KBW Regional Banking Index. The Fund’s performance prior to October 24, 2011 is therefore based on the Fund’s prior investment strategy to track a different benchmark 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. (&#8220;SSgA FM&#8221; or the &#8220;Adviser&#8221;), 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&#8217;s investment objective.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities, including business development companies, 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). </font> <br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index applies an alternative weighting methodology to the S&amp;P Composite 1500 Index so that stocks with relatively low volatility are overweight relative to the S&amp;P Composite 1500 Index and stocks with relatively high volatility are underweight. The S&amp;P 1500 Index, one of the leading indices of the U.S. equity market, is a capitalization-weighted combination of the large-cap S&amp;P 500 Index, the S&amp;P MidCap 400 Index, and the S&amp;P SmallCap 600 Index. In constructing the Index, S&amp;P Dow Jones Indices LLC estimates the volatility of each stock in the S&amp;P Composite 1500 Index based on its monthly price return variance over the past five years, and ranks all 1,500 index constituents in order of volatility. S&amp;P then forms 20 sub-portfolios of approximately equal market capitalization, grouped by volatility. S&amp;P derives a sub-portfolio allocation factor using the inverse of each sub-portfolio&#8217;s volatility, so that a sub-portfolio with relatively low volatility will have a higher allocation factor than a sub-portfolio with relatively high volatility. The weight of each stock in the Index is proportionate to its market capitalization and to its sub-portfolio allocation factor. The Index is rebalanced annually after the close of business on the third Friday of April. As of September 30, 2012, there were approximately 1,500 securities in the Index.</font><br/><br/><font style="FONT-FAMILY: ARIAL" size="2">The Index is sponsored by S&amp;P Dow Jones Indices LLC (the &#8220;Index Provider&#8221;) which is not affiliated with the Fund or the Adviser.

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&#8217;s return to be lower than if the Fund employed an active strategy.</font></blockquote></blockquote><blockquote><blockquote><font style="FONT-FAMILY: ARIAL" size="1"><b>INDEX TRACKING RISK:</b></font><font style="FONT-FAMILY: ARIAL" size="2">&nbsp;&nbsp;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&#8217;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.

Risk/Return [Heading] rr_RiskReturnHeading SPDR® S&P 600 Small Cap ETF
Objective [Heading] rr_ObjectiveHeading INVESTMENT OBJECTIVE
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock
The SPDR S&P 600 Small Cap ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of small capitalization exchange traded U.S. equity securities.
Expense [Heading] rr_ExpenseHeading FEES AND EXPENSES OF THE FUND
Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred indirectly through its ownership in other investment companies, such as business development companies (“BDCs”). BDC expenses are similar to the expenses paid by any operating company held by the Fund. They are not direct costs paid by the Fund shareholders and are not used to calculate the Fund’s net asset value. They have no impact on the costs associated with fund operations. This table and the example below do not reflect brokerage commissions you may pay on purchases and sales of the Fund’s Shares.
Operating Expenses Caption [Text] rr_OperatingExpensesCaption ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment):
Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading PORTFOLIO TURNOVER:
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock 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 13% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 13.00%
Expense Example [Heading] rr_ExpenseExampleHeading EXAMPLE:
Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock 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:
Strategy [Heading] rr_StrategyHeading THE FUND’S PRINCIPAL INVESTMENT STRATEGY
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock In seeking to track the performance of the S&P SmallCap 600 Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index measures the performance of the small-capitalization sector in the U.S. equity market. The selection universe for the Index includes all U.S. common equities, including BDCs, listed on the NYSE, NASDAQ Global Select Market, NASDAQ Select Market and NASDAQ Capital Market with market capitalizations generally between $300 million and $1.4 billion at the time of inclusion. Capitalization ranges may be revised by the Index Provider (as defined below) at any time. To be included in the Index, a security should (i) have an annual dollar value traded to float adjusted market capitalization ratio of 1 or greater; (ii) trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date; (iii) have a public float of at least 50%; and (iv) have four consecutive quarters of positive as-reported earnings. The Index is float-adjusted, market capitalization weighted and changes to the Index are made on an as-needed basis. As of September 30, 2012, the Index was comprised of 603 stocks.

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.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS OF INVESTING IN THE FUND
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock 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.

SMALL CAP RISK:  Small-sized companies may be more volatile and more likely than large- and mid-capitalization companies to have relatively limited product lines, markets or financial resources, or depend on a few key employees. Returns on investments in stocks of small companies could trail the returns on investments in stocks of larger companies.

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.

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.
Risk Lose Money [Text] rr_RiskLoseMoney As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading FUND PERFORMANCE
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index is a float-adjusted market capitalization weighted index that represents the mid-cap portion of the Dow Jones U.S. Total Stock Market Index (“Total Stock Market Index”). The Total Stock Market Index tracks all the U.S. common stocks regularly traded on the New York Stock Exchange, NYSE Amex and the NASDAQ Stock Market. The Index includes the components of the Total Stock Market Index ranked 501-1,000 by full market capitalization. The composition of the Index is assigned based on the semiannual review of the Total Stock Market Index. New issues are added to the Index on a monthly basis as new issues are added to the Total Stock Market Index and fall within the mid cap portion. An issue is removed as soon as prudently possible if it fails to meet the inclusion requirement of the Total Stock Market Index. Shares and float factors of the Index are updated on a quarterly basis. As of September 30, 2012, the Index was comprised of 502 stocks.

The Index is sponsored by S&P Dow Jones Indices LLC (the “Index Provider”) which is not affiliated with the Fund or the Adviser.

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.

SPDR(R) S&P(R) Pharmaceuticals ETF
SPDR® S&P® Pharmaceuticals ETF
INVESTMENT OBJECTIVE
The SPDR S&P Pharmaceuticals ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the pharmaceuticals segment of a U.S. total market composite index.
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):

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:

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 31% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Pharmaceuticals Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the pharmaceuticals industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 31 stocks.

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.
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 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.
PHARMACEUTICALS SECTOR RISK:  The Fund’s assets will generally be concentrated in the pharmaceuticals industry, which means the Fund will be more affected by the performance of the pharmaceuticals industry versus a fund that was more diversified. Companies in the pharmaceutical industry are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of the companies. Pharmaceutical companies are also subject to extensive litigation based on product liability and other similar claims. Many new products are subject to approval of the U.S. Food and Drug Administration (“FDA”). The process of obtaining FDA approval can be long and costly and approved products are susceptible to obsolescence. Pharmaceutical companies are also subject to heavy competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting.
HEALTH CARE SECTOR RISK:   Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.
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.

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.
BUILDING AND CONSTRUCTION SECTOR RISK:  The Fund’s assets will generally be concentrated in the building and construction industry, which means the Fund will be more affected by the performance of the building and construction industry versus a fund that was more diversified. Companies within the Index can be significantly affected by the national, regional and local residential and commercial real estate markets. This industry is also sensitive to interest rate fluctuations which can cause changes in the availability of mortgage capital and directly affect the purchasing power of potential homebuyers. The building industry can be significantly affected by changes in government spending, zoning laws, taxation, consumer confidence, real estate values, demographic patterns, building inventories, and the level of new and existing home sales. Natural disasters and environmental issues can also affect the building industry.
INDUSTRIAL SECTOR RISK:  Stock prices for 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 stocks, 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.
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.
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.

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 period from the commencement of the Fund’s operations (September 28, 2011) to the end of the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P Health Care Services Select Industry Index (the “Index”), the Fund employs a replication strategy, which means that the Fund typically invests 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. 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 SSgA Funds Management, Inc. (“SSgA FM” or the “Adviser”), the investment adviser to the Fund).

The Index represents the health care services industry group of the S&P Total Market Index (“S&P TMI”). The Index is one of twenty-five (25) of the S&P Select Industry Indices (the “Select Industry Indices”), each designed to measure the performance of a narrow sub-industry or group of sub-industries determined based on the Global Industry Classification Standards (“GICS”). Membership in the Select Industry Indices is based on the GICS classification, as well as liquidity and market cap requirements. Companies in the Select Industry Indices are classified based primarily on revenues; however, earnings and market perception are also considered. The Index consists of the S&P TMI constituents belonging to the particular GICS sub-industry or group of sub-industries that satisfy the following criteria: (i) have a float-adjusted market capitalization above $500 million with a float-adjusted liquidity ratio (defined by dollar value traded over the previous 12 months divided by the float-adjusted market capitalization as of the index rebalancing reference date) above 90% or have a float-adjusted market capitalization above $400 million with a float-adjusted liquidity ratio (as defined above) above 150%; and (ii) are U.S. based companies. The length of time to evaluate liquidity is reduced to the available trading period for initial public offerings or spin-offs that do not have 12 months of trading history. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds are included in order of their float-adjusted market capitalization. The market capitalization threshold may be relaxed to ensure that there are at least 22 stocks in the Index as of the rebalancing effective date. Existing Index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below $300 million or their float-adjusted liquidity ratio falls below 50%. The market capitalization threshold and the liquidity threshold are each reviewed from time to time based on market conditions. Rebalancing occurs on the third Friday of the quarter ending month. The S&P TMI tracks all the U.S. common stocks listed on the NYSE (including NYSE Arca and NYSE Amex), the NASDAQ Global Select Market, the NASDAQ Select Market and the NASDAQ Capital Market. The Index is an equal weighted market cap index. As of September 30, 2012, the Index was comprised of 54 stocks.

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.
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 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.

HEALTH CARE SERVICES SECTOR RISK:  The Fund’s assets will generally be concentrated in the health care providers and services industry, which means the Fund will be more affected by the performance of the health care providers and services industry versus a fund that was more diversified. Companies in the health care industry are affected by rising costs of medical products, devices and services and the increased emphasis on the delivery of health care through outpatient services. The health care industry is highly competitive and can be significantly affected by extensive government regulation or government reimbursement for medical expenses. The equipment may be subject to extensive litigation based on malpractice claims, product liability claims or other litigation. Medical equipment manufacturers are heavily dependent on patent protection and the expiration of patents may adversely affect their profitability. Many new health care products are subject to the approval of the U.S. Food and Drug Administration (“FDA”). The process of obtaining FDA approval is often long and expensive.

HEALTH CARE SECTOR RISK:  Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of the companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

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.

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.

For purposes of this Item, a "New Fund" is a Fund that does not include in Form N-1A financial statements reporting operating results or that includes financial statements for the Fund's initial fiscal year reporting operating results for a period of 6 months or less.

SPDR(R) S&P(R) Dividend ETF
SPDR® S&P® Dividend ETF
INVESTMENT OBJECTIVE
The SPDR S&P Dividend ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index that tracks the performance of publicly traded issuers that have historically followed a policy of making dividend payments.
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) S&P(R) Dividend ETF
MANAGEMENT FEES 0.35%
DISTRIBUTION AND SERVICE (12b-1) FEES [1] none
OTHER EXPENSES none
TOTAL ANNUAL FUND OPERATING EXPENSES 0.35%
[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 at least October 31, 2013.
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:

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 94% of the average value of its portfolio.
THE FUND’S PRINCIPAL INVESTMENT STRATEGY
In seeking to track the performance of the S&P High Yield Dividend Aristocrats 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. 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 designed to measure the performance of the highest dividend yielding S&P Composite 1500® Index constituents that have followed a managed-dividends policy of consistently increasing dividends every year for at least 20 consecutive years. Stocks included in the Index have both capital growth and dividend income characteristics, as opposed to stocks that are pure yield, or pure capital oriented, and must meet minimum float-adjusted market capitalization and liquidity requirements. Stocks within the Index are weighted by indicated yield (annualized gross dividend payment per share divided by price per share) and weight-adjusted each quarter. The Index components are reviewed annually in January for continued inclusion in the Index and re-weighted quarterly in April, July and October. A component stock may be removed from the Index if, among other factors, 1) during the January rebalancing, dividends did not increase from the previous year, or 2) at any time during the year, a company is removed from the S&P Composite 1500 Index. As of September 30, 2012, the Index was comprised of 83 stocks.

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.
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 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.

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 following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for certain time periods compare with the average annual returns of the Index. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at http://www.spdrs.com.
ANNUAL TOTAL RETURN (years ended 12/31)
Bar Chart
[1] As of September 30, 2012, the Fund's Calendar Year-To-Date return was 10.35%.
Highest Quarterly Return: 17.28% (Q3 2009)
Lowest Quarterly Return: -16.22% (Q4 2008)
AVERAGE ANNUAL TOTAL RETURNS (for periods ending 12/31/11)
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 an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares.
