Risk Nondiversified Status [Member]

Risk [Text Block]

Non-Diversification Risk
The Fund is non-diversified, which means it may focus its investments in the securities of a comparatively small number of issuers. Investments in securities of a limited number of issuers exposes the Fund to greater market risk, price volatility and potential losses than if assets were diversified among the securities of a greater number of issuers.   Because the Fund may have a focused portfolio of fewer companies than other funds, including both diversified and non-diversified funds, the increase or decrease of the value of a single investment may have a greater impact on the Fund’s net asset value (“NAV”) and total return when compared to other funds.

Asset Selection Risk [Member]

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker or a derivative counterparty, will be unwilling or unable to satisfy its obligation to make timely principal, interest or settlement payments or to otherwise honor its obligations to the Fund.

Cybersecurity and Operational Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund, its service providers and third-party fund distribution platforms, including the ability of shareholders to transact in the Fund’s shares, and result in financial losses. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. The Fund cannot control the cybersecurity and operational plans and systems of its service providers, its counterparties or the issuers of securities in which the Fund invests. The issuers of the Fund’s investments are likely to be dependent on computers for their operations and require ready access to their data and the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of the Fund’s investments, leading to significant loss of value.

Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Derivatives Risk
Derivatives may involve significant risk. The use of derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities or other instruments underlying those derivatives, including the high degree of leverage often embedded in such instruments, and potential material and prolonged deviations between the theoretical value and realizable value of a derivative.
The use of derivatives may also increase any adverse effects resulting from the underperformance of strategies, asset classes and market exposures to which the Fund has allocated its assets. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Certain derivatives may be difficult to value, and valuation may be more difficult in times of market turmoil. Derivatives may also be more volatile than other types of investments. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to counterparty risk  and credit risk. As a result, the Fund may not recover its investment or may only obtain a limited recovery, and any recovery may be delayed.  Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. Derivatives transactions requiring the Fund to post collateral may expose the Fund to greater losses in the event of a default by a counterparty.  There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. The Fund may buy or sell derivatives not traded on an exchange, which may be subject to heightened  counterparty, liquidity and valuation risks. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Ongoing changes to the regulation of derivatives and changes in the regulation of funds using derivative instruments could limit the Fund’s ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance.  In addition, the Fund’s investments in derivatives are subject to the following risks:

 

■ Options Risk. An option is a contract that gives the purchaser (holder) of the option, in return for a premium, the right to buy from (call) or sell to (put) the seller (writer) of the option the asset underlying the option at a specified exercise price at any time during the term of the option (normally not exceeding nine months).  There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the assets underlying them, and there may at times not be a liquid secondary market for
■ Swaptions Risk.  Swaptions enable the Fund to purchase exposure that is significantly greater than the premium paid. Consequently, the value of swaptions can be volatile, and a small investment in swaptions can have a large impact on the performance of the Fund. The Fund risks losing all or part of the cash paid (premium) for purchasing swaptions. Additionally, the value of the option may be lost if the Sub-Advisor fails to exercise such option at or prior to its expiration. As the swaption contracts held by the Fund near expiration, the Fund may replace them with other swaption contracts that have a later expiration date. That process is called “rolling,” and the Fund may incur costs to “roll” swaption contracts.

 

■ Swap Agreements Risk. Swap agreements or “swaps” are transactions in which the Fund and a counterparty agree to pay or receive payments at specified dates based upon or calculated by reference to changes in specified prices or rates or the performance of specified securities, indices or other assets based on a specified amount (the “notional” amount). Swaps can involve greater risks than a direct investment in an underlying asset, because swaps typically include a certain amount of embedded leverage and as such are subject to leverage risk. If swaps are used as a hedging strategy, the Fund is subject to the risk that the hedging strategy may not eliminate the risk that it is intended to offset, due to, among other reasons, the occurrence of unexpected price movements or the non-occurrence of expected price movements. Swaps also may be difficult to value. Swaps may be subject to liquidity risk and counterparty risk, and swaps that are traded over-the-counter are not subject to standardized clearing requirements and may involve greater liquidity and counterparty risks.  The Fund may invest in the following types of swaps:

 

■ Inflation Swaps Risk. There can be no assurance that the CPI-U, the reference rate for the Fund’s inflation swaps, will accurately measure the rate of inflation experienced in the  U.S. or the rate of expected future inflation. Inflation swaps are subject to interest rate risk. The value of an inflation swap is expected to change in response to changes in real interest rates. If nominal interest rates increase at a faster rate than inflation, real interest rates may rise, leading to a decrease in value of an inflation swap. Additionally, because the zero-coupon inflation swaps in which the Fund will invest do not pay interest periodically, the prices of these swaps can be very volatile when interest rates change, their values may fluctuate more and they may be less liquid than swaps that pay interest periodically. The payments received by the Fund from swaps, such as inflation swaps and other types of swaps, discussed below, will result in taxable income, either as ordinary income or capital gains, rather than tax-exempt income, which will increase the amount of taxable distributions received by shareholders.

 

■ Interest Rate Swaps Risk. Interest rate swaps may also be subject to interest rate and market risks. An interest rate swap could result in losses if the underlying asset or reference rate does not perform as anticipated. An interest rate swap may fail to perform as intended and may not offset adverse changes in interest rates fully or at all. An interest rate swap may also reduce the Fund’s gains due to favorable changes in interest rates and result in losses to the Fund.  Counterparties to interest rate swaps are subject to manipulation in the marketplace of the reference benchmark rate, which may affect the utility of the swap as a hedge.
Exchange-Traded Funds (“ETFs”) Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Exchange-Traded Funds (“ETFs”) Risk  
As an ETF, the Fund is subject to the following risks:

 

■ Authorized Participants Concentration Risk. The Fund has a limited number of financial institutions that may act as authorized participants (i.e., large institutions that have entered into agreements with the distributor of the Fund’s shares and are authorized to transact in Creation Units (described below) with the Fund) (“Authorized Participants”). Only an Authorized Participant may transact in Creation Units directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. To the extent they exit the business or are otherwise unable to proceed in creation and redemption transactions with the Fund and no other Authorized Participant is able to step forward to create or redeem shares, then shares of the Fund may be more likely to trade at a premium or discount to net asset value (“NAV”) and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs that invest in securities or instruments that have lower trading volumes.

 

■ Cash Transactions Risk. Like other ETFs, the Fund sells and redeems its shares primarily in large blocks called “Creation Units” and only to Authorized Participants. Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially or fully for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.  

 

■ Premium/Discount Risk. There may be times when the market price of the Fund’s shares is more than its NAV (at a premium) or less than its NAV (at a discount). As a result, shareholders of the Fund may pay more than NAV when purchasing shares and receive less than NAV when selling Fund shares. This risk is heightened in times of market volatility or periods of steep market declines. In such market conditions, market or stop loss orders to sell Fund shares may be executed at prices well below NAV.

 

■ Secondary Market Trading Risk. Investors buying or selling shares in the secondary market will normally pay brokerage commissions, which are often a fixed amount and may be a significant proportional cost for investors buying or selling relatively small amounts of shares. In addition, such investors may incur the cost of the “spread” also known as the bid-ask spread, which is the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). The bid-ask spread varies over time based on, among other things, trading volume, market liquidity and market volatility. Trading in Fund shares may be halted by the Exchange (as defined below) because of market conditions or other reasons. If a trading halt occurs, a shareholder may temporarily be unable to purchase or sell shares of the Fund. In addition, although the Fund’s shares are listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained or that the Fund’s shares will continue to be listed.
Hedging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Hedging Risk
If the Fund uses a hedging instrument at the wrong time or judges the market conditions incorrectly, or the hedged instrument does not correlate to the risk sought to be hedged, the hedge might be unsuccessful, reduce the Fund’s return, or create a loss. In addition, hedges, even when successful in mitigating risk, may not prevent the Fund from experiencing losses on its investments. Hedging instruments may also reduce or eliminate gains that may otherwise have been available had the Fund not used the hedging instruments.

High Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund’s trading activity over a one-year period. The Fund may engage in active and frequent trading, which could increase the Fund’s transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund had lower portfolio turnover.

Inflation Protection  Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Inflation Protection  Risk
Although the Fund seeks to generate positive returns during periods of rising inflation and inflation expectations, the sub-advisor’s investment strategy may fail to achieve this result. If the Fund’s investments do not keep pace with inflation, the real (or inflation-adjusted) value of its assets could decline as their purchasing power decreases. Additionally, due to the Fund’s principal investment strategies, its performance may decline during environments with deflation, or a general decline in prices.

Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Interest Rate Risk
Generally, the value of investments with interest rate risk, such as fixed-income securities or derivatives, will move in the opposite direction as movements in interest rates. Factors including central bank monetary policy, rising inflation rates, and changes in general economic conditions may cause interest rates to rise, which could cause the value of the Fund’s investments to decline.
Interest rate increases, including significant or rapid increases, may result in a decline in the value of bonds or derivatives held by the Fund, make issuers less willing or able to make principal and interest payments on fixed-income investments when due, lead to heightened volatility in the fixed-income markets and adversely affect the liquidity of certain fixed-income investments, any of which may result in substantial losses to the Fund. When interest rates decline, issuers may prepay higher-yielding securities held by the Fund, resulting in the Fund reinvesting in securities with lower yields, which may cause a decline in its income. The prices of fixed-income securities or derivatives are also affected by their  durations. Fixed-income securities or derivatives with longer durations generally have greater sensitivity to changes in interest rates than those with shorter durations. Rising interest rates may cause the value of the Fund’s investments with longer durations and terms to maturity to decline, which may adversely affect the value of the Fund. For example, if a bond has a duration of two years, a 1% increase in interest rates could be expected to result in a 2% decrease in the value of the bond. Fluctuations in interest rates may also affect the liquidity of fixed-income securities and instruments held by the Fund.

Investment Risk [Member]

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Leverage Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Leverage Risk
The Fund’s use of derivative instruments may have the economic effect of financial leverage. Financial leverage magnifies the Fund’s exposure to the movements in prices of an asset or class of assets underlying a derivative instrument and may result in increased volatility, which means that the Fund will have the potential for greater losses than if the Fund does not use the derivative instruments that have a leveraging effect. Leverage may result in losses that exceed the amount originally invested and may accelerate the rate of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the Fund’s net asset value (“NAV”) per share to be volatile. There can be no assurance that the Fund’s use of leverage will be successful.

Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability, be subject to restrictions on sale, be difficult or impossible to purchase or sell at favorable times or prices or become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such instruments may be volatile. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund’s ability to limit losses. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund.  
 Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund’s performance. Equity securities generally have greater price volatility than fixed-income securities, although under certain market conditions fixed-income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last 10-15 years,
but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters, cybersecurity incidents, and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. Changes in value may be temporary or may last for extended periods.

Policy changes by the U.S. government and/or Federal Reserve and economic and political changes within the U.S. and abroad, such as inflation, changes in interest rates, recessions, changes in the  U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat or occurrence of a federal government shutdown and threats or the occurrence of a failure to increase the federal government’s debt limit, which could result in a default on the government’s obligations, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations.

 

■ Recent Market Events Risk. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, during periods of significant volatility, the risks discussed herein associated with an investment in the Fund may be increased. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be changing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

  Some countries, including the  U.S., have adopted more protectionist trade policies, including trade tariffs and other trade barriers, which is a trend that appears to be continuing globally. Slowing global economic growth, the rise in protectionist trade policies, inflationary pressures, changes to some major

 

 

  international trade agreements, risks associated with trade agreements between countries and regions, including the  U.S. and other foreign nations, political or economic dysfunction within some countries or regions, including the U.S., and dramatic changes in consumer sentiment and commodity and currency prices could affect the economies and markets of many nations, including the U.S., in ways that cannot necessarily be foreseen at the present time and may create significant market volatility. In addition, these policies, including the impact on the U.S. dollar, may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

  Although interest rates were unusually low in the  U.S. and abroad for a period of time, in 2022, the U.S. Federal Reserve (the “Federal Reserve”) and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. The Federal Reserve and certain foreign central banks subsequently started to lower interest rates in September 2024, though economic or other factors, such as Federal Reserve policy changes, could have an effect on this. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. Additionally, various economic and political factors could cause the Federal Reserve or foreign central banks to change their approach in the future and such actions may result in an economic slowdown in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets.

 

  High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. There is no assurance that the U.S. Congress will act to raise the nation’s debt ceiling; a failure to do so could cause market turmoil and substantial investment risks that cannot be fully predicted. Unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy.

 

  Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities in the Middle East and between Russia and Ukraine, and any sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.  

 

  Regulators in the  U.S. have adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of various newly adopted regulations is not currently known. Due to the scope of regulations being adopted, certain of these changes to regulations could limit the Fund’s ability to pursue its investment strategies or make certain investments, or may make it more costly for the Fund to operate, which may impact performance.  Additionally, it is possible that recently adopted regulations could be further revised or rescinded, which creates material uncertainty regarding their impact to the Fund.

 

  Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change in ways that cannot be foreseen, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.
Other Investment Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Other Investment Companies Risk
To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity securities, fixed-income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject.
The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

 

■ Exchange-Traded Funds (“ETFs”) Risk. Because ETFs are listed on an exchange, they may be subject to trading halts, may trade at a premium or discount to their net asset value (“NAV”) and may not be liquid. An ETF that tracks an index may not precisely replicate the returns of that index, and an actively-managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. Future legislative or regulatory changes, including changes in taxation, could impact the operation of ETFs.  
■ Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.   Credit risk is the risk that the issuer, guarantor or insurer of an obligation, or the  counterparty to a transaction, may fail or become less able or unwilling, to make timely payment of interest or principal or otherwise honor its obligations, or that it may default completely.

Risk Management
Risk is an essential part of investing. No risk management program can eliminate the Fund’s exposure to adverse events; at best, it can only reduce the possibility that the Fund will be affected by such events, and especially those risks that are not intrinsic to the Fund’s investment program. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

Segregated Assets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the obligation. Segregated assets generally cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value. The need to segregate cash or other liquid securities could limit the Fund’s ability to pursue other opportunities as they arise.

Small Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Small Fund Risk
Like other smaller funds, large inflows and outflows may impact the Fund’s market exposure for limited periods of time. Investment positions may also have a disproportionate impact, negative or positive, on performance, and Fund performance may be more volatile than that of a larger fund. The Fund’s shareholder fees and annual fund operating expenses also may be higher than those of a fund that has attracted sufficient assets to achieve investment and trading efficiencies. Shareholders of the Fund may incur higher expenses if the Fund fails to attract sufficient assets to realize economies of scale. Investors in the Fund also bear the risk that, without sufficient assets, the Fund may not be successful in implementing its investment strategy or may not employ a successful investment strategy.

Treasury Inflation-Protected Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Treasury Inflation-Protected Securities Risk
U.S. Treasury inflation-protected securities (“TIPS”) are debt instruments issued by the United States Department of the Treasury. The principal of TIPS increases with inflation and decreases with deflation, as measured by the CPI-U. When TIPS mature, investors are paid the adjusted principal or original principal, whichever is greater. Interest payments on TIPS are unpredictable and will fluctuate as the principal and corresponding interest payments are adjusted for inflation. TIPS generally pay a lower nominal interest rate than a comparable non-inflation-indexed bond. There can be no assurance that the CPI-U will accurately measure the real rate of inflation in the prices of goods and services. Any increases in the principal amount of TIPS will be considered taxable ordinary income, even though the Fund or ETFs in which the Fund invests will not receive the principal until maturity. As a result, the Fund may make income distributions to shareholders that exceed the cash it receives. In addition, TIPS are subject to interest rate risk.

U.S. Treasury Obligations Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

U.S. Treasury Obligations Risk
The market value of U.S. Treasury obligations may vary due to fluctuations in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s investments in obligations issued by the U.S. Treasury to decline. Certain political events in the U.S., such as a prolonged government shutdown or potential default on the national debt, may also cause investors to lose confidence in the U.S. government and may cause the value of U.S. Treasury obligations to decline.

Valuation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Valuation Risk
Certain of the Fund’s assets may be valued at a price different from the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid, or securities that trade in relatively thin markets and/or markets that experience extreme volatility. The valuation of the Fund’s investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

Volatility Risk [Member]

Volatility Risk
The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s NAV to experience significant increases or declines in value over short periods of time.
