Objective [Heading] | oef_ObjectiveHeading | Investment Goal | ||||||||||||
Objective, Primary [Text Block] | oef_ObjectivePrimaryTextBlock | To seek to provide investment results that closely correspond, before fees and expenses, to the performance of the FTSE South Korea RIC Capped Index (the FTSE South Korea Capped Index). |

Expense Heading [Optional Text] | oef_ExpenseHeading | Fees and Expenses of the Fund | ||||||||||||
Expense Narrative [Text Block] | oef_ExpenseNarrativeTextBlock | The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. You may also incur other fees, such as usual and customary brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example that follows. |

Portfolio Turnover [Heading] | oef_PortfolioTurnoverHeading | Portfolio Turnover | ||||||||||||
Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 25.57% of the average value of its portfolio. |

Expense Example [Heading] | oef_ExpenseExampleHeading | Example | ||||||||||||
Expense Example Narrative [Text Block] | oef_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |

Strategy [Heading] | oef_StrategyHeading | Principal Investment Strategies | ||||||||||||
Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | Under normal market conditions, the Fund invests at least 80% of its assets in the component securities of the FTSE South Korea Capped Index and in depositary receipts representing such securities. The FTSE South Korea Capped Index is a free float-adjusted market capitalization weighted index maintained and calculated by FTSE Russell with a capping methodology applied quarterly to issuer weights so that no single issuer of a component exceeds 25% of the FTSE South Korea Capped Index weight, and all issuers with weights above 5% do not cumulatively exceed 50% of the FTSE South Korea Capped Index’s weight. The FTSE South Korea Capped Index is based on the FTSE South Korea Index and is designed to measure the performance of South Korean large- and mid-capitalization stocks. FTSE Russell determines eligible securities for the FTSE South Korea Capped Index based on measures such as the company’s place of incorporation, listing country, investor protection regulations present in the country of incorporation, tax domicile, location of headquarters/factors of production and currency of denomination. As of May 31, 2025, the FTSE South Korea Capped Index was comprised of 147 securities with capitalizations ranging from $421 million to $273.11 billion. The Fund, using a “passive” or indexing investment approach, seeks investment results that closely correspond, before fees and expenses, to the performance of the FTSE South Korea Capped Index. The Fund may use either a replication strategy or representative sampling strategy. Under a replication strategy, the Fund will replicate the component securities of the FTSE South Korea Capped Index as closely as possible (i.e., invest in all of the component securities in their respective weightings in the FTSE South Korea Capped Index). However, under various circumstances, it may not be possible or practicable to replicate the FTSE South Korea Capped Index. In these circumstances, the Fund may use a “representative sampling” strategy whereby the Fund would invest in what it believes to be a representative sample of the component securities of the FTSE South Korea Capped Index, but may not track the FTSE South Korea Capped Index with the same degree of accuracy as would an investment vehicle replicating the entire FTSE South Korea Capped Index. Under the representative sampling technique, the investment manager will select securities that collectively have an investment profile similar to that of the FTSE South Korea Capped Index, including securities that resemble those included in the FTSE South Korea Capped Index in terms of risk factors, performance attributes and other characteristics, such as market capitalization and industry weightings. The Fund may invest in equity futures (including equity index futures) and equity total return swaps to provide additional opportunities to add value and better track the performance of the Fund’s Underlying Index, such as to equitize cash and accrued income, simulate investments in the Underlying Index, facilitate trading or minimize transaction costs. The Fund may enter into foreign currency forward contracts and/or currency futures contracts to provide the Fund with additional opportunities to add value and better track the performance of the Fund’s Underlying Index, such as by facilitating local securities settlements or protecting against currency exposure in connection with distributions to Fund shareholders. The Fund intends to be diversified in approximately the same proportion as the FTSE South Korea Capped Index is diversified. The Fund may become “non-diversified,” as defined in the 1940 Act, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the FTSE South Korea Capped Index. A “non-diversified” fund generally invests a greater proportion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund. Shareholder approval will not be sought if the Fund becomes non-diversified due solely to a change in the relative market capitalization or index weighting of one or more constituents of the FTSE South Korea Capped Index. The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that the FTSE South Korea Capped Index is concentrated. As of May 31, 2025, the FTSE South Korea Capped Index was concentrated in the information technology sector. |

Franklin FTSE South Korea ETF | Principal Risks | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Principal Risks You could lose money by investing in the Fund. Exchange-traded fund (ETF) shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), trading price, yield, total return and ability to meet its investment goal. |

Franklin FTSE South Korea ETF | Market | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen. Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund. |
||||||||||||
Franklin FTSE South Korea ETF | Foreign Securities (non-U.S.) | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Foreign Securities (non-U.S.): Investing in foreign securities typically involves different risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; diplomatic and political developments could affect the economies, industries, and securities and currency markets of the countries in which the Fund is invested, which can include rapid and adverse political changes; social instability; regional conflicts; sanctions imposed by the United States, other nations or other governmental entities, including supranational entities; terrorism; and war; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. |
||||||||||||
Franklin FTSE South Korea ETF | Geographic Focus | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Geographic Focus: Because the Fund may invest a significant portion of its assets in companies in a specific country and region, the Fund is subject to greater risks of adverse developments in that country, region and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the country or region, even in countries in which the Fund is not invested, may adversely affect the value of investments held by the Fund. |
||||||||||||
Franklin FTSE South Korea ETF | South Korean securities | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | South Korean securities: Investments in South Korean securities may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korea’s neighbors or potential hostilities with North Korea may have an adverse effect on the South Korean economy. The South Korean economy is heavily reliant on trading exports, especially with other Asian countries and the U.S. Conditions that weaken demand for key South Korean exports, and disruptions or decreases in trade activity could lead to declines in economic growth. |
||||||||||||
Franklin FTSE South Korea ETF | Depositary Receipts | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Depositary Receipts: Depositary receipts are subject to many of the risks of the underlying security. For some depositary receipts, the custodian or similar financial institution that holds the issuer's shares in a trust account is located in the issuer's home country. The Fund could be exposed to the credit risk of the custodian or financial institution, and in cases where the issuer’s home country does not have developed financial markets, greater market risk. In addition, the depository institution may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding dividends and interest and corporate actions. The Fund would be expected to pay a share of the additional fees, which it would not pay if investing directly in the foreign securities. The Fund may experience delays in receiving its dividend and interest payments or exercising rights as a shareholder. There may be an increased possibility of untimely responses to certain corporate actions of the issuer in an unsponsored depositary receipt program. Accordingly, there may be less information available regarding issuers of securities underlying unsponsored programs and there may not be a correlation between this information and the market value of the depositary receipts. |
||||||||||||
Franklin FTSE South Korea ETF | Calculation Methodology | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Calculation Methodology: FTSE Russell relies on various sources of information to assess the criteria of issuers included in the FTSE South Korea Capped Index, including information that may be based on assumptions and estimates. Neither the Fund nor the investment manager can offer assurances that FTSE Russell's calculation methodology or sources of information will provide an accurate assessment of included issuers or that the included issuers will provide the Fund with the market exposure it seeks. |
||||||||||||
Franklin FTSE South Korea ETF | Index-Related | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Index-Related: There is no assurance that the FTSE South Korea Capped Index will be determined, composed or calculated accurately. While FTSE Russell provides descriptions of what the FTSE South Korea Capped Index is designed to achieve, FTSE Russell does not guarantee the quality, accuracy or completeness of data in respect of its indices, and does not guarantee that the FTSE South Korea Capped Index will be in line with the described index methodology. Errors in index data, index computations or the construction of the FTSE South Korea Capped Index in accordance with its methodology (including as a result of outdated, unreliable or unavailable market information) may occur and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. Gains, losses or costs to the Fund caused by errors in the FTSE South Korea Capped Index may therefore be borne by the Fund and its shareholders. |
||||||||||||
Franklin FTSE South Korea ETF | Non-Correlation | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Non-Correlation: There is no guarantee that the Fund will achieve a high degree of correlation to the FTSE South Korea Capped Index and therefore achieve its investment goal. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the FTSE South Korea Capped Index. In addition, the Fund’s NAV may deviate from the FTSE South Korea Capped Index if the Fund fair values a portfolio security at a price other than the price used by the FTSE South Korea Capped Index for that security. To the extent that the investment manager uses a representative sampling strategy, the Fund may not track the return of the FTSE South Korea Capped Index as well as it would have if the Fund held all of the securities in the FTSE South Korea Capped Index. |
||||||||||||
Franklin FTSE South Korea ETF | Tracking Error | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Tracking Error: Tracking error is the divergence of the Fund’s performance from that of the FTSE South Korea Capped Index. Tracking error may occur because of differences between the securities held in the Fund’s portfolio and those included in the FTSE South Korea Capped Index, pricing differences (including differences between a security’s price at the local market close and the Fund’s valuation of a security at the time of calculation of the Fund’s NAV), transaction costs, the Fund’s holding of cash, differences in timing of the accrual of dividends or interest, tax gains or losses, changes to the FTSE South Korea Capped Index or the need to meet various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the FTSE South Korea Capped Index does not. |
||||||||||||
Franklin FTSE South Korea ETF | Market Trading | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Market Trading: The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary market. The investment manager cannot predict whether shares will trade above (premium), below (discount) or at NAV. To the extent that the underlying securities held by the Fund trade on an exchange that is closed when the securities exchange on which the Fund shares list and trade is open, there may be market uncertainty about the stale security pricing (i.e., the last quote from its closed foreign market) resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs. |
||||||||||||
Franklin FTSE South Korea ETF | Concentration | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Concentration: To the extent the Fund concentrates in a specific industry, a group of industries, sector or type of investment, the Fund will carry much greater risks of adverse developments and price movements in such industries, sectors or investments than a fund that invests in a wider variety of industries, sectors or investments. There is also the risk that the Fund will perform poorly during a slump in demand for securities of companies in such industries or sectors. |
||||||||||||
Franklin FTSE South Korea ETF | Information technology companies | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Information technology companies: Companies in the information technology sector have historically been volatile due to the rapid pace of product change and development within the sector. For example, their products and services may not prove commercially successful or may become obsolete quickly. In addition, delays in or cancellation of the release of anticipated products or services may also affect the price of an information technology company’s stock. Information technology companies are subject to significant competitive pressures, such as new market entrants, aggressive pricing and tight profit margins. The activities of these companies may also be adversely affected by changes in government regulations, worldwide technological developments or investor perception of a company and/or its products or services. The stock prices of companies operating within this sector may be subject to abrupt or erratic movements. |
||||||||||||
Franklin FTSE South Korea ETF | Change in Diversification Status | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Change in Diversification Status: In seeking to track the FTSE South Korea Capped Index, the Fund may become non-diversified as a result of a change in relative market capitalization or index weighting of one or more constituents of the FTSE South Korea Capped Index. In such circumstances, the Fund may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may negatively impact the Fund’s performance and result in greater fluctuation in the value of the Fund’s shares and greater risk of loss. |
||||||||||||
Franklin FTSE South Korea ETF | Mid Capitalization Companies | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Mid Capitalization Companies: Securities issued by mid capitalization companies may be more volatile in price than those of larger companies and may involve substantial risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, mid capitalization companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans. The markets for securities issued by mid capitalization companies also tend to be less liquid than the markets for securities issued by larger companies. |
||||||||||||
Franklin FTSE South Korea ETF | Derivative Instruments | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Derivative Instruments: The performance of derivative instruments (including currency derivatives) depends largely on the performance of an underlying instrument, such as a currency, security, interest rate or index, and such derivatives often have risks similar to the underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund’s portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that significantly exceeds the Fund’s initial investment. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits and may experience increased tracking error. Their successful use will usually depend on the investment manager’s ability to accurately forecast movements in the market relating to the underlying instrument. Should a market or markets, or prices of particular classes of investments move in an unexpected manner, especially in unusual or extreme market conditions, the Fund may not achieve the anticipated benefits of the transaction, and it may realize losses, which could be significant. If the investment manager is not successful in using such derivative instruments, the Fund’s performance may be worse than if the investment manager did not use such derivatives at all. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate, index or other risk being hedged. Derivatives also may present the risk that the other party to the transaction will fail to perform. There is also the risk, especially under extreme market conditions, that a derivative, which usually would operate as a hedge, provides no hedging benefits at all. |
||||||||||||
Franklin FTSE South Korea ETF | Passive Investment | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Passive Investment: Unlike many investment companies, the Fund is not actively managed and the investment manager does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the investment manager would not necessarily buy or sell a security unless that security is added or removed, respectively, from the FTSE South Korea Capped Index, even if that security generally is underperforming. |
||||||||||||
Franklin FTSE South Korea ETF | Authorized Participant Concentration | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Authorized Participant Concentration: Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. "Authorized Participants" are broker-dealers that are permitted to create and redeem shares directly with the Fund and who have entered into agreements with the Fund’s distributor. The Fund has a limited number of institutions that act as Authorized Participants. To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem Creation Units (as defined below), Fund shares may trade at a discount to NAV and possibly face trading halts and/or delisting. This risk may be more pronounced in volatile markets, potentially where there are significant redemptions in ETFs generally. |
||||||||||||
Franklin FTSE South Korea ETF | Cash Transactions | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Cash Transactions: Unlike certain ETFs, the Fund expects to generally effect its creations and redemptions entirely for cash, rather than for in-kind securities. Therefore, it may be required to sell portfolio securities and subsequently recognize gains on such sales that the Fund might not have recognized if it were to distribute portfolio securities in-kind. As such, investments in Fund shares may be less tax-efficient than an investment in an ETF that distributes portfolio securities entirely in-kind. |
||||||||||||
Franklin FTSE South Korea ETF | Small Fund | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Small Fund: When the Fund's size is small, the Fund may experience low trading volume and wide bid-ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange. |
||||||||||||
Franklin FTSE South Korea ETF | Large Shareholder | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Large Shareholder: Certain large shareholders, including other funds or accounts advised by the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, may from time to time own a substantial amount of the Fund’s shares. In addition, a third-party investor, the investment manager, sub-advisor or an affiliate of the investment manager or sub-advisor, an authorized participant, a lead market maker, or another entity may invest in the Fund and hold its investment for a limited period of time solely to facilitate commencement of the Fund or to facilitate the Fund’s achieving a specified size or scale. There can be no assurance that any large shareholder would not redeem its investment, that the size of the Fund would be maintained at such levels or that the Fund would continue to meet applicable listing requirements. Redemptions by large shareholders could have a significant negative impact on the Fund. In addition, transactions by large shareholders may account for a large percentage of the trading volume on the listing exchange and may, therefore, have a material upward or downward effect on the market price of the shares. |
||||||||||||
Franklin FTSE South Korea ETF | Cybersecurity | ||||||||||||||
Risk/Return: | oef_RiskReturnAbstract | |||||||||||||
Risk [Text Block] | oef_RiskTextBlock | Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, authorized participants, or index providers (as applicable) and listing exchanges, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents. Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time. |
