Defiance KSM Israel 120 ETF | Israeli Issuer Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Israeli Issuer Investing Risk. Investments in securities of Israeli issuers, including issuers located outside of Israel that generate significant revenues from Israel, involve risks and special considerations not typically associated with investments in U.S. securities markets. Israel’s economy depends on imports of key items such as crude oil, natural gas, coal, grains, raw materials and military equipment, which may increase its vulnerability to global supply disruptions and geopolitical developments. Israel has experienced ongoing geopolitical tensions and military conflicts with neighboring countries and non-state actors, including Hamas in the Gaza Strip, Hezbollah in Lebanon, and Iran. On October 7, 2023, Hamas launched a significant attack on Israel from the Gaza Strip. While a ceasefire agreement between Israel and Hamas was reached in January 2025, there is no guarantee that the parties will continue to comply with the terms of the agreement and the agreement does not mean the conflict will be resolved. In February 2026, the United States and Israel launched coordinated military operations against Iran, prompting widespread retaliation by Iran and its proxies with attacks impacting not only Israel but other countries in the region. The possibility of a continued and prolonged conflict between the U.S. and Israel against Iran, the Israel-Hamas conflict, and the potential expansion of conflicts in surrounding regions may adversely affect Israel’s economy, financial markets and the value of securities in which the Fund invests. The Israeli economy is also dependent on external trade with other countries, particularly the United States, China, Japan, Canada and the European Union. A reduction in demand for Israeli exports or adverse economic developments in these countries could negatively affect Israel’s economy and issuers of securities in which the Fund invests.

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks, such as those held by the Fund, are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. 

 

Defiance KSM Israel 120 ETF | Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Securities Risk. Investments in securities or other instruments of non-U.S. issuers involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. Investments in foreign companies’ securities, including investments via depositary receipts, are subject to special risks, including the following:

 

Defiance KSM Israel 120 ETF | Developed Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Developed Markets Risk.  Many developed market countries have heavy indebtedness, which may lead downward pressure on the economies of these countries. As a result, it is possible that interest rates on debt of certain developed countries may rise to levels that make it difficult for such countries to service high debt levels without significant help from other countries or from a central bank. Developed market countries generally are dependent on the economies of certain key trading partners. Changes in any one economy may cause an adverse impact on several developed countries.

 

Defiance KSM Israel 120 ETF | Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Currency Risk. Changes in currency exchange rates can negatively affect securities denominated in and/or receiving revenues in foreign currencies. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s investments in securities denominated in a foreign currency or may widen existing losses. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks.

 

 

Defiance KSM Israel 120 ETF | Depositary Receipt Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (Underlying Shares). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

 

Defiance KSM Israel 120 ETF | Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk. The Fund’s investment exposure will be concentrated in (or substantially exposed to) the same industry or group of industries to the extent the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries. 

 

Defiance KSM Israel 120 ETF | Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. As of the date of this Prospectus, the financial services sector represented a significant portion of the Index.

 

Defiance KSM Israel 120 ETF | Financial Services Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
  Financial Services Sector Risk. Companies in the financial services sector are often subject to risks tied to the global financial markets, which have experienced very difficult conditions and volatility as well as significant adverse trends. The conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions.

 

Defiance KSM Israel 120 ETF | Economic and Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Economic and Market Risk. The Fund’s investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities and other financial instruments. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, inflation, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.

Defiance KSM Israel 120 ETF | Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as Authorized Participants or APs). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services; or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.
Defiance KSM Israel 120 ETF | Costs of Buying or Selling Shares [Member]  
Prospectus [Line Items]  
Risk [Text Block]
   
Costs of Buying or Selling Shares. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the bid-ask spread. The bid-ask spread varies over time for Shares based on trading volume and market liquidity, and is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base in the Fund, asset swings in the Fund and/or increased market volatility may cause increased bid-ask spreads. Due to the costs of buying or selling Shares, including bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. 
Defiance KSM Israel 120 ETF | Shares May Trade at Prices Other Than NAV [Member]  
Prospectus [Line Items]  
Risk [Text Block]
   
Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Trading. Although Shares are listed for trading on a national securities exchange, such as The Nasdaq Stock Market, LLC (the Exchange), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares.

Market Capitalization Risks.

 

Defiance KSM Israel 120 ETF | Large-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
 

Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

     
Defiance KSM Israel 120 ETF | Mid-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
 

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large-capitalization stocks or the stock market as a whole.

Defiance KSM Israel 120 ETF | Small-Capitalization Investing [Member]

  Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.
Defiance KSM Israel 120 ETF | Micro-Capitalization Investing [Member]  
Prospectus [Line Items]  
Risk [Text Block]
     
  Micro-Capitalization Investing. Micro-capitalization companies often have limited product lines, narrower markets for their goods and/or services and more limited managerial and financial resources than larger, more established companies, including companies which are considered small- or mid-capitalization. As a result, their performance can be more volatile and they face greater risk of business failure, which could increase the volatility of the Fund’s portfolio.

 

Defiance KSM Israel 120 ETF | New Fund Risk [Member]  
Prospectus [Line Items]

New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions.

 

Defiance KSM Israel 120 ETF | Operational Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

 

Defiance KSM Israel 120 ETF | Passive Investment Risk [Member]  
Prospectus [Line Items]

Passive Investment Risk. The Fund is not actively managed and does not attempt to outperform the Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to the Index.

 

Defiance KSM Israel 120 ETF | Third Party Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Third Party Data Risk. The composition of the Index, and consequently the Fund’s portfolio, is heavily dependent on information and data calculated and published by an independent third party calculation agent (“Third Party Data”). When Third Party Data proves to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index that would have been excluded or included had the Third Party Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can also be expected to reflect the errors.

 

Defiance KSM Israel 120 ETF | Tracking Error Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in Index components at all times or may hold securities not included in the Index.

 

 

Defiance KSM Israel 120 ETF | Underlying Index Risk [Member]  
Prospectus [Line Items]

Underlying Index Risk. Neither the Fund’s investment adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Index. The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider, or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Risk [Text Block]

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Crypto Asset Market Volatility Risk. The prices of crypto assets have historically been highly volatile, such as steep increases in the value of certain crypto assets during 2021, followed by steep decreases in the value those crypto assets in 2022, a pattern that has occurred in prior periods and, extreme volatility in crypto asset prices continues to persist. Due to such volatility, the value of the Fund’s investments in derivative instruments that provide exposure to crypto assets – and therefore the value of an investment in the Fund – could decline significantly and without warning, including to zero. If you are not prepared to accept significant and unexpected changes in the value of the Fund and the possibility that you could lose your entire investment in the Fund you should not invest in the Fund.

 

Defiance CoinDesk 5 Equal Weight ETF | Crypto Assets Risk [Member]

Crypto Assets Risk. Crypto assets are relatively new and are subject to unique and substantial risks. The Fund’s investment strategy of seeking to track the performance of the Index through investments in financial instruments that the Adviser believes will perform, in combination, in a manner that should track the Index’s performance, is subject to uncertainties, and potential financial losses, associated with exposure to crypto assets. Crypto assets are designed as mediums of exchange and are still an emerging asset class. They operate independently of any central authority or government backing and are subject to regulatory changes and at times extreme price volatility. The trading platforms for digital assets are relatively new, largely unregulated, and thus more vulnerable to fraud and failures compared to traditional, regulated exchanges. Shutdowns of these platforms due to fraud, technical glitches, or security issues can significantly affect digital asset prices and market volatility. This instability and the resultant negative publicity could adversely affect the Fund’s reputation and trading prices. Ongoing crypto asset market turbulence could significantly impact the value of the Fund’s shares. Blockchain technologies, which underpin crypto assets, are relatively new, and many of their applications are untested. The adoption of blockchain and the development of competing platforms or technologies could affect its usage. Investments in companies or vehicles that utilize blockchain technology are subject to market volatility and may experience lower trading volumes compared to more established industries. Additionally, regulatory changes, internet disruptions, cybersecurity incidents, and intellectual property disputes could further affect the adoption and functionality of blockchain technology.

 

 

As of the date of this Prospectus, the constituent crypto assets included in the Index were Bitcoin (BTC), Ethereum (ETH), Binance Coin (BNB), Ripple (XRP) and Solana (SOL).

 

Defiance CoinDesk 5 Equal Weight ETF | Bitcoin (BTC) Risk [Member]

Bitcoin (BTC) Risk  

 

Bitcoin’s price is highly volatile, and its market is influenced by the changing Bitcoin network, fluctuating acceptance levels, and unpredictable usage trends. Not being a legal tender and operating outside central authority systems like banks, Bitcoin faces potential government restrictions. For instance, some countries may limit or ban Bitcoin transactions, negatively impacting their market value.

 

The risks associated with Bitcoin include the possibility of fraud, theft, market manipulation, and security breaches in trading platforms. A small group of large Bitcoin holders, known as “whales,” can significantly influence Bitcoin’s price. The largely unregulated nature of Bitcoin and its trading venues heightens risks of fraudulent activities and market manipulation, which could affect Bitcoin’s price. For example, if a group of miners gains control over a majority of the Bitcoin network, they could manipulate transactions to their advantage. Historical instances have seen Bitcoin trading venues shut down due to fraud or security breaches, often leaving investors without recourse and facing significant losses.

 

Updates to Bitcoin’s software, proposed by developers, can lead to the creation of new digital assets, or “forks,” if not broadly adopted. This can impact Bitcoin’s demand and the Fund’s performance. The extreme volatility of Bitcoin’s market price can result in shareholder losses. Furthermore, the operation of Bitcoin exchanges may be disrupted or cease altogether due to various issues, further affecting Bitcoin’s price and the Fund’s investments.

 

The value of Bitcoin has historically been subject to significant speculation, making trading and investing in Bitcoin reliant on market sentiment rather than traditional fundamental analysis. Bitcoin’s price can be influenced by events unrelated to its security or utility, including instability in other speculative areas of the crypto/blockchain space, potentially leading to substantial declines in its value.

 

Risks associated with crypto asset trading platforms include fragmentation, regulatory non-compliance, and the possibility of enforcement actions by regulatory authorities, which could impact the valuation of Bitcoin.

 

The security of the Bitcoin blockchain may be compromised if a single miner or group controls more than 50% of the network’s hashing power, where hashing power refers to the computational capacity used to validate and secure transactions on the blockchain. Proposed changes to the Bitcoin protocol may not be universally adopted, leading to the creation of competing blockchains (forks) with different assets and participants, exemplified by past forks like Bitcoin Cash and Bitcoin SV. The Bitcoin blockchain protocol may contain vulnerabilities that attackers could exploit to disrupt its operation, potentially compromising the security and reliability of the network.

 

Emerging alternative public blockchains, particularly those emphasizing privacy through technologies like zero-knowledge cryptography, pose risks and challenges to the dominance of the Bitcoin blockchain as a payment system. Common impediments to adopting the Bitcoin blockchain as a payment network include slow transaction processing, variability in transaction fees, and the volatility of Bitcoin’s price, which may deter widespread adoption by businesses and consumers. Adoption and use of other blockchains supporting advanced applications like smart contracts present challenges to the dominance of the Bitcoin blockchain, potentially impacting its long-term relevance and utility in the evolving landscape of blockchain technology.

 

The development and use of “Layer II solutions” are critical for the scalability and functionality of the Bitcoin blockchain, but they also introduce risks such as off-chain transaction execution, which could affect transparency and security. Layer II solutions are off-chain protocols that improve scalability and reduce transaction costs by processing transactions outside the main blockchain network.

Ethereum (ETH) Risk

 

Ether or ETH, the native coin of the Ethereum Network, is a relatively new and is subject to unique and substantial risks. The market for ether is subject to rapid price swings, changes and uncertainty. The further development of the Ethereum Network and the acceptance and use of ether are subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the Ethereum Network or the acceptance of ether may adversely affect the price and liquidity of ether. Ether is subject to the risk of fraud, theft, manipulation or security failures, operational or other problems that impact ether trading venues. Additionally, if one or a coordinated group of validators were to gain control of 33% or more of staked ether (i.e., ether that is deposited to support the Ethereum Network), they would have the ability to execute extensive attacks, manipulate transactions and fraudulently obtain ether. If such a validator or group of validators were to gain control of one-third of staked ether, they could halt payments.

 

 

A significant portion of ether is held by a small number of holders sometimes referred to as “whales.” Transactions by these holders may influence the price of ether. The value of ether may be substantially dependent on speculation, such that trading and investing in ether generally may not be based on fundamental analysis. The exposure of ether to instability and other speculative parts of the blockchain crypto industry, such as an event that is not necessarily related to the security or utility of the Ethereum Network, can nonetheless precipitate a significant decline in the price of ether. There are risks related to fragmentation and lack of regulatory compliance with regard to crypto asset trading platforms. The crypto asset trading platforms upon which ether is traded are or may become subject to enforcement actions by regulatory authorities.

 

Unlike the exchanges for more traditional assets, such as equity securities and futures contracts, ether and ether trading venues are largely unregulated. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote ether in a way that artificially increases the price of ether). Investors may be more exposed to the risk of theft, fraud and market manipulation than when investing in more traditional asset classes. Over the past several years, a number of ether trading venues have been closed due to fraud, failure or security breaches. Investors in ether may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses. The realization of any of these risks could result in a decline in the acceptance of ether and consequently a reduction in the value of ether.

 

Legal or regulatory changes may negatively impact the operation of the Ethereum Network or restrict the use of ether. For example, if ether were determined to be or were expected to be determined to be a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in ether, trading in ether futures may become significantly more volatile and/or completely halted, and the value of an investment in the Underlying ETPs and/or the Fund could decline significantly and without warning, including to zero.

 

The creation of a “fork” (as described above) or a substantial giveaway of ether (sometimes referred to as an “air drop”) may result in significant and unexpected declines in the value of ether. A fork may be intentional, such as the ‘Merge.’ The ‘Merge’ refers to protocol changes altering the method by which transactions are validated.

Binance Coin (BNB) Risk

 

Binance Coin, also referred to as BNB, is relatively new and subject to unique and substantial risks related to its market and underlying network (BNB Chain). The BNB Chain and the software used to operate it are in the early stages of development. The BNB Chain has only been in existence since 2019. While the BNB token was initially launched in 2017 on the Ethereum blockchain as an ERC-20 token, it migrated to the BNB Chain following its launch. BNB markets have a limited performance record, making them part of a new and rapidly evolving industry that is subject to a variety of factors that are difficult to evaluate. The price of BNB has experienced periods of extreme volatility and may be influenced by a wide variety of factors. Speculators and investors who seek to profit from trading and holding BNB generate a significant portion of BNB demand. Such speculation regarding the potential future appreciation in the value of BNB may cause the price of BNB to increase. Conversely, a decrease in demand for or speculative interest regarding BNB may cause the price to decline.

 

BNB is subject to the risk of manipulation. If one or a coordinated group of validators were to gain control of a significant proportion of staked BNB, they could (depending on the proportion of control gained), impede, reverse or prevent confirmation of transactions, or alter the network causing a “fork” in the blockchain. Forks refer to protocol changes altering the method by which transactions are validated. This potential risk is amplified due to a significant portion of BNB being held by a small number of holders, sometimes referred to as “whales.” Transactions by these holders may influence the price of BNB and these holders may have the ability to manipulate the price of BNB. BNB has in the past experienced intentional forks, such as planned hard forks and network upgrades.

 

The BNB Chain is still in the process of developing and making significant decisions that will affect policies that govern the supply and issuance of BNB as well as other BNB Chain protocols. The open-source nature of many digital asset network protocols, such as the protocol for the BNB Chain, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. As a result, the developers and other contributors of a particular digital asset may lack a financial incentive to maintain or develop the network, or may lack the resources to adequately address emerging issues. Alternatively, some developers may be funded by companies whose interests are at odds with other participants in a particular digital asset network. If the BNB Chain does not successfully develop its policies on supply and issuance, and other major design decisions or does so in a manner that is not attractive to network participants it could lead to a decline in adoption of the BNB Chain and price of BNB.

 

 

As the development of the BNB Chain is ongoing, future disruptions, outages, bugs, or other problems could have a material adverse effect on the value and volatility of BNB. The BNB Chain has reportedly suffered multiple network outages, including those arising from security vulnerabilities (e.g., bridge exploit pause in 2022) and denial of service and bot attacks (e.g., disruption due to sandwich bot attacks in 2024). Also, in the past, bugs, defects and flaws in the BNB Chain source code have been exposed and exploited, including flaws that disrupted normal blockchain network or smart contract operations, or disabled related functionality for users and/or resulted in the theft of digital assets. In the future, the cryptography underlying the BNB Chain could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the BNB Chain, resulting in normal operations and functionality of the BNB Chain being negatively affected. Such losses of functionality could lead to the BNB Chain losing attractiveness to users, nodes, validators, or other stakeholders, thereby dampening demand for BNB.

 

Software applications running on top of the BNB Chain (often referred to as “decentralized applications” or “DApps,” whether or not decentralized in fact) and smart contract developers depend on being able to obtain BNB to be able to run their programs and operate their businesses. As such, they represent a significant source of demand for BNB. BNB’s price volatility (particularly where BNB prices increase), or the BNB Chain’s wider inability to meet the demands of decentralized applications and smart contracts in terms of inexpensive, reliable, and prompt transaction execution, or to solve its scaling challenges or increase its throughput, may discourage such decentralized application and smart contract developers from using the BNB Chain as the foundational infrastructure layer for building their applications and smart contracts. If decentralized application and smart contract developers abandon the BNB Chain for other blockchain or digital asset networks or protocols, the value of BNB could be negatively affected.

 

Legal or regulatory changes may negatively impact the operation of the BNB Chain or restrict the use of BNB. For example, if BNB were determined or were expected to be determined to be offered and sold as a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in BNB.

Ripple (XRP) Risk

 

Ripple, also referred to as XRP, is a relatively new innovation and is subject to unique and substantial risks. XRP operates as a decentralized, peer-to-peer financial trading platform and value storage that is used like money. However, it has no central governmental or banking authority, is not backed by any government and not a legal tender. The markets for XRP may be less liquid and more volatile than other markets for more established products. It may be difficult to execute an XRP trade at a specific price when there is a relatively small volume of buy and sell orders in the XRP market. A market disruption can also make it more difficult to liquidate a position or find a suitable counterparty at a reasonable cost.

 

The market for XRP is subject to rapid price swings, changes and uncertainty. A significant portion of the demand for XRP may be the result of speculation. The value of XRP has been, and may continue to be, substantially dependent on speculation. Such speculation regarding the potential future appreciation of the price of XRP may artificially inflate or deflate the price of XRP and increase volatility. A significant portion of XRP is held by a small number of holders sometimes referred to as “whales.” Transactions by these holders may influence the price of XRP and these holders may have the ability to manipulate the price of XRP.

 

The further development of the XRP Ledger and the acceptance and use of XRP may be subject to a variety of factors that are difficult to evaluate. The slowing, stopping or reversing of the development of the XRP Ledger or the acceptance of XRP may adversely affect the price and liquidity of XRP. A network of independent validator nodes validates transactions on the XRP Ledger. Any node can act as a validator, but the XRP Ledger depends on the UNL, a list of trusted validators. If more than 20% of the validators on a server’s UNL disagree, the server stops validating new ledgers to avoid potential inconsistencies or attacks. If this occurs, it is referred to as a “fork” and can result in one portion of the network running the pre-modification source code and the other portion of the network running the modified source code – an event that could negatively impact the value of XRP. If one or more malicious actors obtain control of greater than 20% of the validators on the XRP Ledger, those validators may cause the network to fail to reach a consensus and throw new transactions on the XRP Ledger into doubt. If a malicious actor took control of more than 80% of the validator nodes, those validators would have the ability to manipulate the XRP Ledger, create and engage in invalid transactions, or otherwise break the rules of the network.

 

XRP is subject to the risk of fraud, theft, manipulation, securities failures, and operational or other problems that impact XRP trading venues. Unlike the exchanges for more traditional assets, such as equity securities and established futures contracts, XRP and XRP trading venues are largely unregulated and may be operating out of compliance with applicable regulation. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote XRP in a way that may artificially increase the price of XRP). Investors may be more exposed to the risk of theft, fraud, market manipulation, and operational failures than when investing in more traditional asset classes. Over the past several years, a number of XRP trading venues have been closed due to fraud, failure or security breaches. Investors in XRP may have little or no recourse should such theft, fraud or manipulation occur and could suffer significant losses.

 

 

The XRP Ledger has historically maintained high availability but has experienced notable disruptions. Ripple reported an unusual 15-minute latency spike on August 15, 2025, which affected only a selective group of peer connections rather than the entire network. This issue was determined to have been caused by external factors, such as temporary internet service provider (ISP) congestion or specific network routing changes. On November 25, 2024, the XRP Ledger faced a disruption of approximately 10-minutes when several nodes crashed and restarted simultaneously, briefly halting transaction processing. No asset losses occurred during these incidents, and built-in safety protocols operated to support network recovery in both cases. On February 4, 2025, the XRP Ledger experienced an unexpected halt in block production for approximately 64 minutes. During that time no new ledgers were validated, temporarily pausing all transactions. In December 2023, the launch of an “XRP Script” initiative led to a 350% increase in daily transactions from users creating low-value non-fungible tokens (NFTs). This surge in activity caused congestion, as validators struggled to keep up with the transaction demands, causing the transaction processing to temporarily fall to just 50 per second, far below the XRP Ledger’s typical capacity of 1,500 transactions per second.

 

Legal or regulatory changes may negatively impact the operation of the XRP protocol and network or restrict the use of XRP. For example, if XRP were determined or were expected to be determined to be offered and sold as a security under the federal securities laws, it is possible certain trading venues would no longer facilitate trading in XRP.

If one or a coordinated group of validators were to gain control of a significant proportion of SOL, they could (depending on the proportion of control gained), impede, reverse or prevent confirmation of transactions, causing a fork in the blockchain that could result in one portion of the network running the pre-modification software and the other portion of the network running the modified software – an event that could negatively impact the value of SOL and in turn the value of the Fund. Gaining such control over the network could also result in manipulation of the blockchain and cast doubt on new SOL transactions on the Solana Network.

 

SOL is subject to the risk of fraud, theft, manipulation, securities failures, and operational or other problems that impact SOL trading venues. Unlike the exchanges for more traditional assets, such as equity securities and established futures contracts, SOL and SOL trading venues are largely unregulated and may be operating out of compliance with applicable regulation. As a result of the lack of regulation, individuals or groups may engage in fraud or market manipulation (including using social media to promote SOL in a way that may artificially increase the price of SOL).

Defiance CoinDesk 5 Equal Weight ETF | Crypto Asset ETF and ETP Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]

Crypto Asset ETF and ETP Risk. The Fund may invest directly in ETFs or ETPs that gain exposure to crypto assets indirectly through the use of derivatives that use them as reference assets. ETFs and ETPs are subject to management fees and other fees that may increase their costs versus the costs of investing in other types of investments. When the Fund invests directly in ETFs or ETPs, it will indirectly bear its proportionate share of management fees and other expenses that are charged by them, in addition to the management fees and other expenses paid by the Fund, resulting in the Fund incurring higher and duplicative expenses to the extent it invests directly in underlying ETFs or ETPs. There is also the risk that the Fund may suffer losses due to the investment practices of the underlying ETFs or ETPs. The Fund will be subject to substantially the same risks as those associated with the direct ownership of the assets held by the underlying ETFs and ETPs. Additionally, the market price of the shares of underlying ETFs or ETPs in which the Fund invests will fluctuate based on changes in the values of their underlying assets as well as changes in the supply and demand of their shares in the secondary market. It is also possible that an active secondary market for shares of an underlying ETF or ETP may not develop, and market trading in such shares may be halted under certain circumstances. ETFs and ETPs investing directly or indirectly in crypto assets are relatively new investment products and therefore these investment products may have limited operating histories.

 

The Fund may invest in shares of certain ETPs that directly hold spot or physical crypto assets plus cash (known as “spot ETPs”). In addition to the risks above, such spot ETPs pose additional risks due to their direct holdings of crypto assets including (i) security threats to their spot crypto asset accounts at custodians resulting in loss of assets or reputational damage; (ii) valuation difficulties due to the price volatility and potential limited liquidity of crypto assets; and (iii) safekeeping lapses or default by custodians for spot crypto asset ETPs. Such spot ETPs may not be registered under the 1940 Act and therefore lack the protections expressly provided by the 1940 Act, including: provisions preventing insiders from managing a spot ETP to their benefit and to the detriment of shareholders; provisions preventing an underlying spot ETP from issuing securities having inequitable or discriminatory provisions; provisions preventing management by irresponsible persons; provisions preventing the use of unsound or misleading methods of computing underlying spot ETP earnings and net asset value; provisions prohibiting suspension of redemptions (except under limited circumstances); provisions limiting leverage; provisions imposing a fiduciary duty on managers with respect to receipt of compensation for services; and provisions preventing changes in an underlying spot ETP’s character without the consent of shareholders.

Derivatives Risk. The Fund’s derivative investments carry risks such as an imperfect match between the derivative’s performance and its underlying assets or index, and the potential for loss of principal, which can exceed the initial investment. Additionally, there are risks related to the possible default of the transaction’s counterparty and the illiquidity of derivatives, making them hard to sell or trade. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract due to financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The derivatives used by the Fund may give rise to a form of leverage. Leverage magnifies the potential for gain and the risk of loss. Certain of the Fund’s transactions in derivatives could also affect the amount, timing, and character of distributions to shareholders, which may result in the Fund realizing more short-term capital gain and ordinary income subject to tax at ordinary income tax rates than it would if it did not engage in such transactions, which may adversely impact the Fund’s after-tax returns.

Swap Agreements Risk.

 

The use of swap transactions is a highly specialized activity, which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify counterparties for those swap agreements. If the Adviser is unable to enter into swap agreements that provide exposure to the crypto assets represented by the Index, the Fund may not meet its stated investment objective. Additionally, any financing, borrowing or other costs associated with using swap transactions may also have the effect of lowering the Fund’s return.

 

The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivatives instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets or instruments. The gross return to be exchanged or swapped between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in a basket of securities.

 

If a derivative investment has a dramatic move that causes a material decline in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to immediately close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to achieve exposure consistent with the Fund’s investment objective. This may prevent the Fund from achieving its investment objective, even if the investment later reverses all or a portion of its movement.

Options Contracts Risk.

 

The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international political events, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The value of the options contracts in which the Fund invests is substantially influenced by the value of the underlying crypto assets used as reference instruments. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in the values of options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund intends to continuously maintain indirect exposure to crypto assets through the use of options contracts, as the options contracts it holds are exercised or expire it will enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. The use of options to generate leverage introduces additional risks, including significant potential losses if the market moves unfavorably. The leverage inherent in options can amplify both gains and losses, leading to increased volatility and potential for substantial losses, particularly in periods of market uncertainty or low liquidity. Additionally, the Fund may incur losses if the value of a crypto asset moves against its positions, potentially resulting in a complete loss of the premium paid.

Futures Contracts Risk - Generally

 

Risks of futures contracts include: (i) an imperfect correlation between the value of the futures contract and the underlying asset; (ii) possible lack of a liquid secondary market; (iii) the inability to close a futures contract when desired; (iv) losses caused by unanticipated market movements, which may be unlimited; (v) the inability to predict correctly the direction of prices, interest rates, currency exchange rates and other economic factors; (vi) an obligation for the Fund to make daily cash payments to maintain its required margin, particularly at times when the Fund may have insufficient cash; and (vii) unfavorable execution prices from rapid selling. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, futures contracts normally specify a certain date for settlement in cash based on the reference asset. As the futures contracts approach expiration, they may be replaced by similar contracts that have a later expiration. This process is referred to as “rolling.” If the market for these contracts is in “contango,” meaning that the prices of futures contracts in the nearer months are lower than the price of contracts in the distant months, the sale of the near-term month contract would be at a lower price than the longer-term contract, resulting in a cost to “roll” the futures contract. The actual realization of a potential roll cost will be dependent upon the difference in price of the near and distant contract.

Futures Contracts Risk – Crypto Assets

 

The market for crypto asset futures contracts may be less developed, and potentially less liquid and more volatile, than more established futures markets. While the markets for crypto asset futures contracts have grown substantially in recent years, there can be no assurance that this growth will continue. The price for a crypto asset futures contract is based on a number of factors, including the supply of and the demand for the specific crypto asset traded in the futures markets. Market conditions and expectations, regulatory limitations or limitations imposed by the listing exchanges or futures commission merchants (“FCMs”) (e.g., margin requirements, position limits, and accountability levels), collateral requirements, availability of counterparties, and other factors each can impact the supply of and demand for crypto asset futures contracts and limit the Fund’s ability to achieve its desired exposure to crypto assets. If the Fund is unable to achieve such exposure, it may not be able to meet its investment objective and the Fund’s returns may be different or lower than expected. Additionally, collateral requirements may require the Fund to liquidate its positions, potentially incurring losses and expenses, when it otherwise would not do so. Investing in derivatives like crypto asset futures contracts may be considered aggressive and may expose the Fund to significant counterparty, liquidity and other risks.

 

 

The performance of crypto asset futures contracts, in general, has historically been highly correlated to the performance of their underlying crypto asset, but there can be no assurance that this will continue. Transaction costs (including the costs associated with futures investing), position limits, the availability of counterparties and other factors may impact the cost of crypto asset futures contracts and decrease the correlation between the performance of crypto asset futures contracts and their corresponding crypto asset, over short or even long-term periods. In the event that there are persistent disconnects between the performance of crypto assets and their respective crypto asset futures contracts, the Fund may not be able to obtain the desired leveraged exposure and may not be able to achieve its investment objective. In addition, the performance of distant month futures contracts is likely to differ more significantly from the performance of the spot prices of crypto assets. To the extent the Fund is invested in distant month crypto asset futures contracts, the performance of the Fund’s crypto asset futures contracts should be expected to deviate more significantly from the performance of the corresponding crypto asset. Moreover, price differences between a crypto asset and its corresponding crypto asset futures contracts will expose the Fund to risks different from, and possibly greater than, the risks associated with investing directly in a crypto asset, including larger losses or smaller gains.

 

Defiance CoinDesk 5 Equal Weight ETF | Counterparty Risk [Member]

Risk [Text Block]

Counterparty Risk. The Fund is subject to counterparty risk by virtue of its investments in derivatives which exposes the Fund to the risk that the counterparty will not fulfill its obligation to the Fund. Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. A counterparty’s inability to fulfill its obligation may result in significant financial loss to the Fund and the Fund may be unable to recover its investment from such counterparty or may obtain a limited and/or delayed recovery.

 

Counterparties may seek to hedge their exposure to individual clients (such as the Fund) by establishing offsetting exposures with other clients, however, there is no guarantee that counterparties will do so under all circumstances. Should a counterparty (e.g., a swap counterparty) terminate its relationship with the Fund, the Fund will seek to utilize other counterparties to seek to maintain its exposures. In addition, the Fund may use options contracts to seek to generate the leverage necessary to implement its strategy. The use of options contracts introduces distinct risks, including heightened volatility, particularly intraday. While options may provide an ancillary benefit of mitigating some losses under specific scenarios, such as severe market downturns, their inherent leverage and rapid price fluctuations can amplify the Fund’s performance volatility and lead to greater risks of substantial losses. Refer to “Derivatives Risk – Options Contracts Risks” for additional information on the risks of investing in options.

 

In addition, the Fund may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. Further, there is a risk that no suitable counterparties will be willing to enter into, or continue to enter into, transactions with the Fund and, as a result, the Fund may not be able to achieve its investment objective.

Cayman Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The futures contracts, other derivatives and other investments held by the Subsidiary are subject to the same economic risks that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Subsidiary. If Cayman Islands law changes such that the Subsidiary must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns. In addition, the Subsidiary is also subject to many of the risks to which the Fund is subject, such as tax risks, commodity related risks, and market and data risks.

Risk [Text Block]

Commodity-Linked Derivatives Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations, or other legally binding authority. As a RIC, the Fund must derive at least 90% of its gross income each taxable year from certain qualifying sources of income under the Code. If, as a result of any adverse future legislation, U.S. Treasury regulations, and/or guidance issued by the Internal Revenue Service (the “IRS”), the income of the Fund from certain commodity-linked derivatives, including income from the Fund’s investments in the Subsidiary, were treated as non-qualifying income, the Fund may fail to qualify as RIC and/or be subject to federal income tax at the Fund level. The treatment of the commodity-linked derivative instruments that provide exposure to the Index under the qualification tests for a RIC is not entirely clear, and the uncertainty surrounding the treatment of these instruments may limit the Fund’s use of such derivative instruments.

 

The Fund intends to limit its investment in the Subsidiary to no more than 25% of the value of its total assets in order to satisfy certain asset diversification requirements for taxation as a regulated investment company. The Fund intends to manage the exposure to the Subsidiary so that the Fund’s investments in the Subsidiary do not exceed 25% of the total assets at the end of any quarter. If the Fund’s investments in the Subsidiary were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC.

Risk [Text Block]

Commodity Pool Regulatory Risk. The Fund’s investment exposure to commodity futures and swaps will cause it to be deemed to be a commodity pool, thereby subjecting the Fund to regulation under the CEA and CFTC rules. The Adviser is registered as a commodity pool operator (“CPO”) and the Fund will be operated in accordance with applicable CFTC rules, as well as the regulatory scheme applicable to registered investment companies. Registration as a CPO imposes additional compliance obligations on the Adviser and the Fund related to additional laws, regulations, and enforcement policies, which could increase compliance costs and may affect the operations and financial performance of the Fund. However, the Fund’s status as a commodity pool and the Adviser’s registration as a CPO are not expected to materially adversely affect the Fund’s ability to achieve its investment objective. The CFTC has not passed on the adequacy of this Prospectus.

Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant.

Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares.

Reverse Repurchase Agreements Risk. The Fund may invest in reverse repurchase agreements. Reverse repurchase agreements are transactions in which the Fund sells portfolio securities to financial institutions such as banks and broker-dealers, and agrees to repurchase them at a mutually agreed-upon date and price which is higher than the original sale price. Reverse repurchase agreements are a form of leverage and the use of reverse repurchase agreements by the Fund may increase the Fund’s volatility. The Fund incurs costs, including interest expenses, in connection with the opening and closing of reverse repurchase agreements that will be borne by the shareholders.

 

 

Reverse repurchase agreements are also subject to the risk that the other party to the reverse repurchase agreement will be unable or unwilling to complete the transaction as scheduled, which may result in losses to the Fund. In situations where the Fund is required to post collateral with a counterparty, the counterparty may fail to segregate the collateral or may commingle the collateral with the counterparty’s own assets. As a result, in the event of the counterparty’s bankruptcy or insolvency, the Fund’s collateral may be subject to the conflicting claims of the counterparty’s creditors, and the Fund may be exposed to the risk of a court treating the Fund as a general unsecured creditor of the counterparty, rather than as the owner of the collateral. There can be no assurance that a counterparty will not default and that the Fund will not sustain a loss on a transaction as a result.

 

Reverse repurchase agreements also involve the risk that the market value of the securities sold by the Fund may decline below the price at which it is obligated to repurchase the securities. In addition, when the Fund invests the proceeds it receives in a reverse repurchase transaction, there is a risk that those investments may decline in value. In this circumstance, the Fund could be required to sell other investments in order to meet its obligations to repurchase the securities.

Risk [Text Block]

U.S. Government and U.S. Agency Obligations Risk. The Fund may invest in securities issued by the U.S. government or its agencies or instrumentalities. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities, such as the U.S. Treasury. Payment of principal and interest on U.S. Government obligations may be backed by the full faith and credit of the United States or may be backed solely by the issuing or guaranteeing agency or instrumentality itself. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities (including government-sponsored enterprises) where it is not obligated to do so.

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
