The Fund may become nondiversified, as defined under the Investment Company Act of 1940, solely as a result of tracking an index.  This could occur due to events such as an index rebalance or market movement. A nondiversified fund may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified funds. In addition, the Fund could become concentrated in an industry or group of industries if the Target Index becomes concentrated due to market conditions or the performance of a single or related group of issuers.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund&#x2019;s performance may be lower than it would be if it were actively managed. Although the Fund seeks to hold substantially all of the securities included in the Target Index, it may be unable to do so. In addition, the Fund could be prevented from holding one or more securities in the same proportion as in the Target Index. The performance of the Fund&#x2019;s investments,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in the aggregate,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

The Fund&#x2019;s ETF Shares are listed for trading on NYSE Arca and individual investors may only buy and sell them on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price of an ETF Share and its NAV differ significantly. Disruptions to creation and redemption transactions, the existence of significant market volatility, or potential lack of an active trading market for ETF Shares (including through a trading halt), as well as other factors, may result in ETF Shares trading significantly above (at a premium) or below (at a discount) the Fund&#x2019;s NAV or the intraday value of the Fund&#x2019;s holdings.

Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund&#x2019;s performance may be hurt disproportionately by the poor performance of its investments in such&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;country or region.&lt;/span&gt;</oef:RiskTextBlock>

Currency exchange rates may be volatile, move rapidly, and change as a result of changes in interest rates, inflation rates, government surpluses or deficits, and monetary policy or currency controls imposed by local governments or supranational entities such as the International Monetary Fund.

Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges. The performance of funds that invest in a subset of market caps could diverge from the performance of a fund that is focused on a broader representation of the stock market.&lt;/span&gt;</oef:RiskTextBlock>

Companies in the energy sector can be negatively affected by various factors, including fluctuations in the prices of oil, gas, and other commodities, as well as changes in supply and demand for energy resources. Operational risks such as exploration and production costs and the success or failure of exploration efforts also play a role. Additionally, shifts in consumer preferences, economic factors such as rising inflation or unemployment, and/or increased competition can impact the sector. Government regulations, changes in policies of the Organization of Petroleum Exporting Countries (OPEC), relationships among OPEC members and between OPEC and oil-importing nations, energy transition efforts, and/or environmental litigation further contribute to the sector&#x2019;s&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;volatility.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:-8.6pt;"&gt;&#x2022;&#x2002;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;font-style:italic;font-weight:bold;"&gt;Utilities Sector.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;Due to the Fund&#x2019;s heavy investment in companies within the utilities sector, its performance will be impacted by the general health of the sector.

The Fund seeks to generate above average compounded returns by purchasing securities in companies and industries where capital spending is declining, and seeks to avoid companies, assets, and business models that can be easily replicated. Companies, assets, and business models that cannot be easily replicated may include those with differentiated offerings, a low-cost advantage, or that maintain an advantage over competitors in their same industry. The Fund typically invests across a range of sectors, a mix of developed and emerging markets stocks, and typically holds companies across the market capitalization spectrum.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:10.5pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified funds.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:10.5pt;"&gt;As a matter of fundamental policy, the Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in securities of issuers whose principal business activities are in the precious metals and mining industry.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

The advisor considers the investment universe, sector-by-sector and region-by-region, looking for companies with strong long-term fundamentals that also meet the advisor&#x2019;s ESG criteria. The advisor will place an emphasis on the following company attributes: (1) a proven track record of effective capital allocation; (2) leading ESG practices as determined by the advisor through an evaluation of how the company integrates material ESG risks and opportunities into its corporate strategy (e.g., a realistic assessment of long-term ESG risks and opportunities, increased transparency into the company&#x2019;s ESG practices, management teams with aligned incentives, better governance practices, and thoughtful resource allocation); and (3) confidence that a wide gap between return on capital and cost of capital can be sustained. The advisor will then examine issues outside the scope of traditional research&#x2014;such as corporate culture, adaptability, and employee engagement&#x2014;to build conviction in each holding.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

The advisor selects securities for the Fund based on the ESG criteria described in the Fund&#x2019;s principal investment strategies. As a result,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the Fund&#x2019;s investments could, in the aggregate, trail the returns of other funds that use ESG criteria or underperform the market as a whole. The advisor&#x2019;s use of ESG criteria may result in the Fund becoming focused, at times, in a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector. Interpretations of what it means for a company or issuer to exhibit ESG characteristics can&#x2014;and do&#x2014;vary significantly across individuals, advisors, and other funds that use ESG criteria. The advisor&#x2019;s assessment of whether or not a company or issuer meets the ESG criteria described in the Fund&#x2019;s principal investment strategies, or the ESG criteria  itself, may not align with your personal view of what it means for a company or issuer to exhibit ESG characteristics generally. Further, individual securities held by the Fund may not reflect your personal preferences, beliefs, expectations, and/or values. In order to assess a company or issuer against the ESG criteria described in the Fund&#x2019;s principal investment strategies, the advisor depends on the availability of data obtained through voluntary or third-party reporting. There can be no assurance that this data will be accurate, complete, or current, which could result in an inaccurate assessment of a company or issuer.&lt;/span&gt;</oef:RiskTextBlock>

In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, market volatility, and fluctuations in the value of the Fund&#x2019;s investments, thereby resulting in potential losses to the Fund over short or long periods.&lt;/span&gt;</oef:RiskTextBlock>

World events could adversely affect the value and/or liquidity of securities of foreign companies or foreign issuers, potentially in ways that differ from impacts to U.S. companies or issuers. Further, global economies and financial markets are becoming increasingly interconnected, which increases the possibility that conditions in one country or region could adversely impact a different country or region. In addition, the rights and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;remedies associated with investments in a fund that invests in foreign securities may be different than a fund that invests in domestic securities. To the extent that the Fund invests a large portion of its assets in securities of issuers located primarily in one country or region, the Fund&#x2019;s performance may be hurt disproportionately by the poor performance of its investments in such country or region.&#x202f;&lt;/span&gt;</oef:RiskTextBlock>

Compared with developed markets, emerging markets can have greater custodial and operational risks; less developed legal, tax, regulatory, financial reporting, accounting, and recordkeeping systems; and greater political, social, and economic instability than developed markets. In addition, emerging markets generally have less efficient trading markets with lower overall liquidity and more volatile currency exchange rates. Each of these risks can cause losses to the Fund&#x2019;s investments and/or impact the Fund&#x2019;s performance.&lt;/span&gt;</oef:RiskTextBlock>

Companies can be further classified into micro- or mega-cap. Different factors can affect each market cap uniquely, and historically small- and mid-cap stocks have typically been more volatile due to the effects of changing economic conditions. Large companies may not reach the same levels of growth or performance as smaller companies, and they may be slower to react to competitive challenges.

The GICS real estate sector is composed of equity real estate investment trusts (known as REITs), which include specialized REITs, and real estate management and development companies. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund attempts to replicate the Target Index by investing all, or substantially all, of its assets in the stocks that make up the Target Index, either directly or indirectly through a wholly owned subsidiary (the &#x201c;Underlying Real Estate Fund&#x201d;). The Fund seeks to hold each stock in approximately the same proportion as its weighting in the Target Index. The Underlying Real Estate Fund is a registered investment company. The Fund may invest a portion of its assets in the Underlying Real Estate Fund.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified funds.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;As a matter of fundamental policy, the Fund concentrates its investments (i.e., invests more than 25% of its assets) in the securities of issuers whose principal business activities are in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;industry.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Companies in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;sector can be negatively affected by various factors, including, but not limited to, supply and demand for properties, changes in interest rates, general or local economic conditions,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the strength of specific industries that rent properties, and/or regulatory changes. Real estate companies might be heavily focused on one geographic market, which could affect those companies more than companies with greater geographic diversification. Real estate companies may rely on leverage, which, while used to help magnify returns, also has the negative effect of magnifying losses. In addition, the real estate industry historically has been sensitive to economic downturns and other events that limit demand for real estate, which would adversely impact the value of real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;investments.&lt;/span&gt;</oef:RiskTextBlock>

Equity REITs may be affected by changes in the value of the underlying properties they own. An individual REIT&#x2019;s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. Interest rate increases can make it more difficult and costly to acquire financing, which could restrict cash flows and negatively affect their operations and values. During periods of rising interest rates, REIT stock prices overall may decline, which could result in a decline in the Fund&#x2019;s value. In addition, unlike corporations, REITs do not have to pay income taxes if they meet certain Internal Revenue Code requirements. Loss of IRS status as a qualified REIT would negatively impact the REIT&#x2019;s overall investment returns.&lt;/span&gt;</oef:RiskTextBlock>

These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market.

The performance of the Fund&#x2019;s investments,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;in the aggregate,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

The GICS real estate sector is composed of equity real estate investment trusts (known as REITs), which include specialized REITs, and real estate management and development companies. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund attempts to replicate the Target Index by investing all, or substantially all, of its assets in the stocks that make up the Target Index, either directly or indirectly through a wholly owned subsidiary (the &#x201c;Underlying Real Estate Fund&#x201d;). The Fund seeks to hold each stock in approximately the same proportion as its weighting in the Target Index. The Underlying Real Estate Fund is a registered investment company. The Fund may invest a portion of its assets in the Underlying Real Estate Fund.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified funds.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;As a matter of fundamental policy, the Fund concentrates its investments (i.e., invests more than 25% of its assets) in the securities of issuers whose principal business activities are in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;industry.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Companies in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;sector can be negatively affected by various factors, including, but not limited to, supply and demand for properties, changes in interest rates, general or local economic conditions,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the strength of specific industries that rent properties, and/or regulatory changes. Real estate companies might be heavily focused on one geographic market, which could affect those companies more than companies with greater geographic diversification. Real estate companies may rely on leverage, which, while used to help magnify returns, also has the negative effect of magnifying losses. In addition, the real estate industry historically has been sensitive to economic downturns and other events that limit demand for real estate, which would adversely impact the value of real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;investments.&lt;/span&gt;</oef:RiskTextBlock>

Equity REITs may be affected by changes in the value of the underlying properties they own. An individual REIT&#x2019;s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. Interest rate increases can make it more difficult and costly to acquire financing, which could restrict cash flows and negatively affect their operations and values. During periods of rising interest rates, REIT stock prices overall may decline, which could result in a decline in the Fund&#x2019;s value. In addition, unlike corporations, REITs do not have to pay income taxes if they meet certain Internal Revenue Code requirements. Loss of IRS status as a qualified REIT would negatively impact the REIT&#x2019;s overall investment returns.&lt;/span&gt;</oef:RiskTextBlock>

These factors, which can be real or perceived, may include economic, market, political, and regulatory conditions and developments as well as local, regional, or global events such as wars, military conflicts, natural disasters, and public health issues. In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market. These factors can contribute to market uncertainty, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;market volatility, and fluctuations in the value of the Fund&#x2019;s investments, thereby resulting in potential losses to the Fund over short or long periods.&lt;/span&gt;</oef:RiskTextBlock>

Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund&#x2019;s performance may be lower than it would be if it were actively managed. Although the Fund seeks to hold substantially all of the securities included in the Target Index, it may be unable to do so.

This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

The GICS real estate sector is composed of equity real estate investment trusts (known as REITs), which include specialized REITs, and real estate management and development companies. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund attempts to replicate the Target Index by investing all, or substantially all, of its assets in the stocks that make up the Target Index, either directly or indirectly through a wholly owned subsidiary (the &#x201c;Underlying Real Estate Fund&#x201d;). The Fund seeks to hold each stock in approximately the same proportion as its weighting in the Target Index. The Underlying Real Estate Fund is a registered investment company. The Fund may invest a portion of its assets in the Underlying Real Estate Fund.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with diversified funds.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;As a matter of fundamental policy, the Fund concentrates its investments (i.e., invests more than 25% of its assets) in the securities of issuers whose principal business activities are in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;industry.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Companies in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;sector can be negatively affected by various factors, including, but not limited to, supply and demand for properties, changes in interest rates, general or local economic conditions,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the strength of specific industries that rent properties, and/or regulatory changes. Real estate companies might be heavily focused on one geographic market, which could affect those companies more than companies with greater geographic diversification. Real estate companies may rely on leverage, which, while used to help magnify returns, also has the negative effect of magnifying losses. In addition, the real estate industry historically has been sensitive to economic downturns and other events that limit demand for real estate, which would adversely impact the value of real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;investments.&lt;/span&gt;</oef:RiskTextBlock>

Equity REITs may be affected by changes in the value of the underlying properties they own. An individual REIT&#x2019;s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. Interest rate increases can make it more difficult and costly to acquire financing, which could restrict cash flows and negatively affect their operations and values. During periods of rising interest rates, REIT stock prices overall may decline, which could result in a decline in the Fund&#x2019;s value. In addition, unlike corporations, REITs do not have to pay income taxes if they meet certain Internal Revenue Code requirements. Loss of IRS status as a qualified REIT would negatively impact the REIT&#x2019;s overall investment returns.&lt;/span&gt;</oef:RiskTextBlock>

In addition, investor sentiment and expectations regarding these factors can also impact the markets. Different parts of the market, including different industries and sectors as well as different types of securities, may react differently to factors that affect the market.

This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

The GICS real estate sector is composed of equity real estate investment trusts (known as REITs), which include specialized REITs, and real estate management and development companies. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in the stocks that make up the Target Index.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund attempts to replicate the Target Index by investing all, or substantially all, of its assets in the stocks that make up the Target Index, either directly or indirectly through a wholly owned subsidiary (the &#x201c;Underlying Real Estate Fund&#x201d;). The Fund seeks to hold each stock in approximately the same proportion as its weighting in the Target Index. The Underlying Real Estate Fund is a registered investment company. The Fund may invest a portion of its assets in the Underlying Real Estate Fund.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;The Fund is considered nondiversified, as defined under the Investment Company Act of 1940, which means that it may invest a greater percentage of &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;its assets in the securities of particular issuers as compared with diversified funds.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;As a matter of fundamental policy, the Fund concentrates its investments (i.e., invests more than 25% of its assets) in the securities of issuers whose principal business activities are in the real estate industry.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Companies in the real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;sector can be negatively affected by various factors, including, but not limited to, supply and demand for properties, changes in interest rates, general or local economic conditions,&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;the strength of specific industries that rent properties, and/or regulatory changes. Real estate companies might be heavily focused on one geographic market, which could affect those companies more than companies with greater geographic diversification. Real estate companies may rely on leverage, which, while used to help magnify returns, also has the negative effect of magnifying losses. In addition, the real estate industry historically has been sensitive to economic downturns and other events that limit demand for real estate, which would adversely impact the value of real estate&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;investments.&lt;/span&gt;</oef:RiskTextBlock>

Equity REITs may be affected by changes in the value of the underlying properties they own. An individual REIT&#x2019;s performance depends on the types and locations of the properties it owns and on how well the REIT manages its properties. Interest rate increases can make it more difficult and costly to acquire financing, which could restrict cash flows and negatively affect their operations and values. During periods of rising interest rates, REIT stock prices overall may decline, which could result in a decline in the Fund&#x2019;s value. In addition, unlike corporations, REITs do not have to pay income taxes if they meet certain Internal Revenue Code requirements. Loss of IRS status as a qualified REIT would negatively impact the REIT&#x2019;s overall investment returns.&lt;/span&gt;</oef:RiskTextBlock>

In addition, investor sentiment and expectations regarding these factors can also impact &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;the markets.

Because the Fund generally seeks to track the performance of the Target Index regardless of how the Target Index is performing, the Fund&#x2019;s performance may be lower than it would be if it were actively managed.

This risk, known as tracking error risk, may be heightened during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target Index made by the index provider or by errors made by the index provider. Any gains, losses, or costs associated with or resulting from an error made by the index provider will generally be borne by the Fund and, as a result, the Fund&#x2019;s shareholders.  &lt;/span&gt;</oef:RiskTextBlock>

Disruptions to creation and redemption transactions, the existence of significant market volatility, or potential lack of an active trading market for ETF Shares (including through a trading halt), as well as other factors, may result in ETF Shares trading significantly above (at a premium) or below (at a discount) the Fund&#x2019;s NAV or the intraday value of the Fund&#x2019;s holdings. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.&lt;/span&gt;</oef:RiskTextBlock>
