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>

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. 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>

The Fund has, and may in the future, distribute current income or capital gains. Though the Fund seeks to invest in the stocks that make up its Target Index, its ability to do so may be affected by its tax-management strategy.

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.

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>

Because the Fund does not hold all of the securities included in the Target Index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of the full Target Index. Additionally, the performance of the Fund&#x2019;s investments, in the aggregate, may not match the investment performance of the Target Index. This risk, known as tracking error risk, may be heightened &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;during times of increased market volatility or under other unusual market conditions. The Fund also could be negatively impacted by changes to the Target &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;Index made by the index provider or by errors made by the index  &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;provider. Any gains, losses, or costs associated with or resulting from an error made by the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt;index provider will generally be borne by the Fund and, as a &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;result, the Fund&#x2019;s shareholders.&lt;/span&gt;</oef:RiskTextBlock>

The performance of nondiversified funds may be negatively impacted by relatively few securities or even a single security and their shares may experience significant fluctuations in value.&lt;/span&gt;</oef:RiskTextBlock>

In addition, investor sentiment and expectations regarding these factors can also impact the markets.

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>

Because the Fund does not hold all of the securities included in the Target Index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of the full Target Index. Additionally, the performance of the Fund&#x2019;s investments, in the aggregate, 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>

With respect to the fixed income portion of the portfolio, the Fund employs an active management approach, investing approximately 50% to 55% of its assets in municipal securities, concentrating in high-quality municipal securities with a dollar-weighted average maturity expected to be between 6 and 12 years. Typically, the Fund invests at least 75% of its fixed income assets in municipal bonds rated in one of the top three credit-rating categories as determined by an independent bond-rating agency (e.g. Aaa, Aa, and A by Moody&#x2019;s) or, if unrated, determined to be of comparable quality by the advisor.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;For the equity portion of the portfolio, the balance of the Fund that is not invested in municipal securities is primarily invested in common stocks. The Fund&#x2019;s stock holdings are chosen from the stocks included in the Russell 1000 Index (the &#x201c;Target Index&#x201d;), which consists of common stocks of large- and mid-size U.S. companies. The Fund uses statistical methods to sample the Target Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Target Index in terms of key risk factors and other characteristics, while seeking to achieve capital gains and income tax efficiency.&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;line-height:11.5pt;"&gt;For the Fund to pay tax-exempt dividends to shareholders from interest attributable to its investment in municipal securities, the Fund is required under U.S. federal income tax law to have at least 50% of the value of its total assets consist of tax-exempt obligations at the close of each quarter of the Fund&#x2019;s taxable year. The Fund has in the past sold, and likely will be required in the future to sell, equity securities to comply with this requirement, which under certain market conditions will cause the Fund to realize capital gains. Although the Fund attempts to minimize capital gains when selling equity securities, there can be no guarantee that the Fund will not realize capital gains when doing so, which could result in a distribution of capital gains to shareholders.&lt;/span&gt;</oef:StrategyNarrativeTextBlock>

Market conditions or other circumstances may limit the Fund&#x2019;s ability to generate tax losses or to generate dividend income taxed at favorable tax rates. The Fund has, and may in the future, distribute current income or capital gains. Though the Fund seeks to invest in the stocks that make up its Target Index, its ability to do so may be affected by its tax-management strategy. As a result, the Fund&#x2019;s pre-tax performance may be lower than that of a similar fund that is not tax-managed. The Fund&#x2019;s tax-management strategy may also cause the Fund to underperform the broader market. For example, the Fund may hold a security in order to achieve more favorable tax-treatment or sell a security to create tax losses, either of which may impact 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. 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>

For example, as a general rule, bond prices and interest rates move in opposite directions. When interest rates rise, bond prices tend to fall, and when interest rates fall, bond prices tend to go up. Bond income also is affected by changes in interest rates. Interest rates can rise or fall for a number of reasons, including, but not limited to, central bank monetary policy, inflationary or deflationary pressures, and changes in general market and economic conditions. Changing interest rates, including, but not limited to, rates that fall below zero, could have unpredictable effects on the overall market and may expose the bond markets in particular to heightened volatility and potential illiquidity. The degree to which the Fund is impacted by certain bond market risks may vary based on factors disclosed in its principal investment strategies, such as the types of bonds in which it invests and the overall credit quality, average maturity, and/or average duration of its bond holdings.&lt;/span&gt;</oef:RiskTextBlock>

The values of the Fund&#x2019;s municipal bond holdings could be impacted significantly by economic, regulatory, political, or other developments or circumstances affecting municipal bond issuers. These developments or circumstances could create uncertainty in the municipal bond market and/or adversely impact the ability of municipal bond issuers to make principal and interest payments, which could result in a loss to the Fund. Municipal bonds can vary from one another in a number of ways, which can impact their sensitivity to certain risks. For example, investing in revenue bonds, which make up a significant portion of the municipal bond market, will generally subject the Fund to a higher risk of loss than investing in municipal bonds secured by the full faith, credit, and taxing power of the issuer (general obligation bonds). Because the interest and principal on revenue bonds is payable only from a particular stream of revenue, they generally carry more &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;font-style:italic;font-weight:bold;"&gt;Credit Risk&lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;"&gt; than general obligation bonds. Revenue bonds also tend to be more sensitive to economic conditions than general obligation bonds, which could make their prices more volatile. The Fund also is subject to the risk that all or a significant portion of its municipal bond holdings will be affected in the same manner. Because many municipal bonds are issued to finance similar projects, conditions in related sectors could have an outsized impact on the municipal bond market. As a result, the Fund may underperform funds that invest more broadly.&lt;/span&gt;</oef:RiskTextBlock>

If the proceeds from a called bond generate taxable income, the Fund may need to distribute income subject to federal or state personal income tax or to the federal alternative minimum tax.

Market conditions or other circumstances may limit the Fund&#x2019;s ability to generate tax losses or to generate dividend income taxed at favorable tax rates. The Fund has, and may in the future, distribute current income or capital gains. Though the Fund seeks to invest in the stocks that make up its Target Index, its ability to do so may be affected by its tax-management strategy.

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>

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>

Because the Fund does not hold all of the securities included in the Target Index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of the full Target Index. Additionally, the performance of the Fund&#x2019;s investments, in the aggregate, 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>

Market conditions or other circumstances may limit the Fund&#x2019;s ability to generate tax losses or to generate dividend income taxed at favorable tax rates. The Fund has, and may in the future, distribute current income or capital gains. Though the Fund seeks to invest in the stocks that make up its Target Index, its ability to do so may be affected by its tax-management strategy.

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, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:9.5pt;margin-left:0.0pt;"&gt;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>

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>

Because the Fund does not hold all of the securities included in the Target Index, it is subject to the risk that the representative sample of securities selected by the advisor will, in the aggregate, vary from the investment profile of the full Target Index. Additionally, the performance of the Fund&#x2019;s investments, in the aggregate, 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>
