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

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006408_Member">As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.&lt;blockquote&gt;&lt;b&gt;Passive Strategy/Index Risk: &lt;/b&gt;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&amp;#8217;s return to be lower than if the Fund employed an active strategy.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Index Tracking Risk: &lt;/b&gt;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&amp;#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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Consumer Discretionary Sector Risk: &lt;/b&gt;The Fund&amp;#8217;s assets will be concentrated in the consumer discretionary sector, which means the Fund will be more affected by the performance of the consumer discretionary sector than a fund that was more diversified. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competition  and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund. As a result, the Fund&amp;#8217;s performance may be disproportionately impacted by the performance of relatively few securities.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

The Fund will provide shareholders with at least 60 days notice prior to any material change in this 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund).&lt;br/&gt;&lt;br/&gt; The Index includes companies from the following industries: media; retail (specialty, multiline, internet &amp;amp; catalog); hotels, restaurants &amp;amp; leisure; textiles, apparel &amp;amp; luxury goods; household durables; automobiles; auto components; distributors; leisure equipment &amp;amp; products; and diversified consumer services. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 83 stocks.&lt;br/&gt;&lt;br/&gt; The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;). Neither entity is affiliated with the Fund or the Adviser. The Index Compilation Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006414_Member">In seeking to track the performance of 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. &lt;br /&gt;&lt;br /&gt; Under normal market conditions, the Fund generally invests substantially all, but at least 95%, 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 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund).&lt;br/&gt;&lt;br/&gt;The Index includes companies from the following industries: chemicals; metals &amp;amp; mining; paper &amp;amp; forest products; containers &amp;amp; packaging; and construction materials. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 30 stocks. &lt;br/&gt;&lt;br/&gt; The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;).&lt;br/&gt;&lt;br/&gt;   Neither entity is affiliated with the Fund or the Adviser. The Index Compilation Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.</rr:StrategyNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006410_Member">In seeking to track the performance of 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. &lt;br /&gt;&lt;br /&gt;Under normal market conditions, the Fund generally invests substantially all, but at least 95%, 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 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund). &lt;br /&gt;&lt;br /&gt;The Index includes companies from the following industries: oil, gas &amp;amp; consumable fuels; and energy equipment &amp;amp; services. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 43 stocks. &lt;br /&gt;&lt;br /&gt;The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;). Neither entity is affiliated with the Fund or the Adviser. The Index Compilation  Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.&lt;br /&gt;&lt;br /&gt;</rr:StrategyNarrativeTextBlock>
  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006414_Member">As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.&lt;blockquote&gt;&lt;b&gt;Passive Strategy/Index Risk: &lt;/b&gt; 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&amp;#8217;s return to be lower than if the Fund employed an active strategy.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Index Tracking Risk: &lt;/b&gt; 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&amp;#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.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Materials Sector Risk: &lt;/b&gt; The Fund&amp;#8217;s assets will be concentrated in the materials sector, which means the Fund will be more affected by the performance of the materials sector than a fund that was more diversified. Many companies in this sector are significantly affected by the level and volatility of commodity prices, the exchange value of the dollar, import controls, worldwide competition, environmental policies and consumer demand. At times, worldwide production of industrial materials has exceeded demand as a result of over-building or economic  downturns, leading to poor investment returns or losses. Other risks may include liabilities for environmental damage and general civil liabilities, depletion of resources, and mandated expenditures for safety and pollution control. The basic industries sector may also be affected by economic cycles, technical progress, labor relations, and government regulations.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Equity Investing Risk: &lt;/b&gt; 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.&lt;br /&gt;&lt;br /&gt; &lt;b&gt;Non-Diversification Risk: &lt;/b&gt; The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund. As a result, the Fund&amp;#8217;s performance may be disproportionately impacted by the performance of relatively few securities.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006416_Member">In seeking to track the performance of 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. &lt;br /&gt;&lt;br /&gt;Under normal market conditions, the Fund generally invests substantially all, but at least 95%, 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 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund). &lt;br /&gt;&lt;br /&gt;The Index includes companies from the following industries: electric utilities; multi-utilities; independent power producers &amp;amp; energy traders; and gas utilities. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 31 stocks. &lt;br /&gt;&lt;br /&gt;The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;).  &lt;br /&gt;&lt;br /&gt;Neither entity is affiliated with the Fund or the Adviser. The Index Compilation Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006416_Member">As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.&lt;blockquote&gt;&lt;b&gt;Passive Strategy/Index Risk: &lt;/b&gt;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&amp;#8217;s return to be lower than if the Fund employed an active strategy.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Index Tracking Risk: &lt;/b&gt;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&amp;#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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Utilities Sector Risk: &lt;/b&gt;The Fund&amp;#8217;s assets will be concentrated in the utilities sector, which means the Fund will be more affected by the performance of the utilities sector than a fund that was more diversified. Stock prices for companies in the utilities sector are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs due to political  and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company&amp;#8217;s earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility equity securities may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company&amp;#8217;s equipment unusable or obsolete and negatively impact profitability.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund. As a result, the Fund&amp;#8217;s performance may be disproportionately impacted by the performance of relatively few securities.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund. As a result, the Fund&amp;#8217;s performance may be disproportionately impacted by the performance of relatively few securities.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

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&amp;#8217;s return to be lower than if the Fund employed an active strategy.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Index Tracking Risk: &lt;/b&gt;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&amp;#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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Consumer Staples Sector Risk: &lt;/b&gt; The Fund&amp;#8217;s assets will be concentrated in the consumer staples sector, which means the Fund will be more affected by the performance of the consumer staples sector than a fund that was more diversified. Companies in the Index are subject to government regulation affecting their products which may negatively impact such companies&amp;#8217; 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, including performance of the overall domestic and international economy, interest rates, competition and consumer confidence and spending.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund.

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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund.

The Fund will provide shareholders with at least 60 days notice prior to any material change in this 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund). &lt;br/&gt;&lt;br/&gt;The Index includes companies from the following industries: diversified financial services; insurance; commercial banks; capital markets; real estate investment trusts (&amp;#8220;REITs&amp;#8221;); consumer finance; thrifts &amp;amp; mortgage finance; and real estate management &amp;amp; development. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 81 stocks. &lt;br/&gt;&lt;br/&gt; The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;). Neither entity is affiliated with the Fund or the Adviser.

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006410_Member">As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.&lt;blockquote&gt;&lt;b&gt;Passive Strategy/Index Risk: &lt;/b&gt;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.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Index Tracking Risk: &lt;/b&gt;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.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Energy Sector Risk: &lt;/b&gt;The Fund's assets will be concentrated in the energy sector, which means the Fund will be more affected by the performance of the energy sector than a fund that was more diversified. Energy companies in the Index develop and produce oil, gas and consumable fuels 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, exploration and production spending, world events and economic conditions, swift price and supply fluctuations, energy conservation, the success of exploration projects, liabilities for environmental damage and general civil liabilities and tax and other governmental regulatory policies. 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.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;br/&gt;&lt;br/&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even 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.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

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. 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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund.

  <rr:PortfolioTurnoverTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006415_Member">The Fund pays transaction costs, such as commissions, when it buys and sells securities (or &amp;#8220;turns over&amp;#8221; 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&amp;#8217;s performance. During the most recent fiscal year, the Fund&amp;#8217;s portfolio turnover rate was 5.28% of the average value of its portfolio.</rr:PortfolioTurnoverTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006415_Member">In seeking to track the performance of 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.&lt;br/&gt;&lt;br/&gt;Under normal market conditions, the Fund generally invests substantially all, but at least 95%, 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 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund).&lt;br/&gt;&lt;br/&gt;The Index includes companies from the following industries: computers &amp;amp; peripherals; software; diversified telecommunication services; communications equipment; semiconductors &amp;amp; semiconductor equipment; internet software &amp;amp; services; IT services; electronic equipment, instruments &amp;amp; components; wireless telecommunication services; and office electronics. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 78 stocks.&lt;br/&gt;&lt;br/&gt;The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;). Neither entity is affiliated with the Fund or the Adviser. The Index Compilation Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.</rr:StrategyNarrativeTextBlock>

  <rr:RiskNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006415_Member">As with all investments, there are certain risks of investing in the Fund, and you could lose money on an investment in the Fund.&lt;blockquote&gt;&lt;b&gt;Passive Strategy/Index Risk: &lt;/b&gt;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&amp;#8217;s return to be lower than if the Fund employed an active strategy.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Index Tracking Risk: &lt;/b&gt;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&amp;#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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Technology Sector Risk: &lt;/b&gt;The Fund&amp;#8217;s assets will be concentrated in the technology sector, which means the Fund will be more affected by the performance of the technology sector than a fund that was more diversified. 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&amp;#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. 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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Equity Investing Risk: &lt;/b&gt;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.&lt;/blockquote&gt;&lt;blockquote&gt;&lt;b&gt;Non-Diversification Risk: &lt;/b&gt;The Fund is non-diversified and may invest a larger percentage of its assets in securities of a few issuers or even a single issuer than that of a diversified fund. As a result, the Fund&amp;#8217;s performance may be disproportionately impacted by the performance of relatively few securities.&lt;/blockquote&gt;</rr:RiskNarrativeTextBlock>

  <rr:StrategyNarrativeTextBlock contextRef="Duration_01Feb2012_31Jan2013S000006412_Member">In seeking to track the performance of 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.&lt;br/&gt;&lt;br/&gt; Under normal market conditions, the Fund generally invests substantially all, but at least 95%, 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 95% investment policy. In addition, the Fund may invest in 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. (&amp;#8220;SSgA FM&amp;#8221; or the &amp;#8220;Adviser&amp;#8221;), the investment adviser to the Fund). &lt;br/&gt;&lt;br/&gt; The Index includes companies from the following industries: pharmaceuticals; health care equipment &amp;amp; supplies; health care providers &amp;amp; services; biotechnology; life sciences tools &amp;amp; services; and health care technology. The Index is one of nine Select Sector Indexes developed and maintained in accordance with the following criteria: (1) each of the component securities in the Index is a constituent company of the S&amp;amp;P 500 Index; (2) each stock in the S&amp;amp;P 500 Index is allocated to one and only one of the Select Sector Indexes; and (3) the Index is calculated by Standard &amp;amp; Poor&amp;#8217;s (the &amp;#8220;Index Provider&amp;#8221;) using a modified &amp;#8220;market capitalization&amp;#8221; methodology. This design ensures that each of the component stocks within a Select Sector Index is represented in a proportion consistent with its percentage with respect to the total market capitalization of such Select Sector Index. Under certain conditions, however, the weighting of a component stock within the Select Sector Index may be adjusted to conform to Internal Revenue Code requirements. As of December 31, 2012, the Index was comprised of 52 stocks. &lt;br/&gt;&lt;br/&gt; The Index is sponsored by the Index Provider and compiled by BofA Merrill Lynch Research (the &amp;#8220;Index Compilation Agent&amp;#8221; or &amp;#8220;BofA Merrill Lynch&amp;#8221;). Neither entity is affiliated with the Fund or the Adviser. The Index Compilation Agent, in consultation with the Index Provider, determines the composition of the Index and relative weightings of the securities in the Index. The Index Provider publishes information regarding the market value of the Index.</rr:StrategyNarrativeTextBlock>
