Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the S&P 500® Index (the “S&P 500”), (ii) 50% to the S&P 500 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the S&P 500 and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the S&P 500 is based on the total return version of the S&P 500 and reflects the reinvestment of dividends paid by the securities in the S&P 500. The Index is expected to be predominantly invested in the components of the S&P 500 over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below. The S&P 500 consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective at the close of business on the first business day after the indicator for the change is triggered. The Index will be in a new position effective on the second business day.
Equity Indicator. When the S&P 500 closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the S&P 500, effective at the close of business on the first business day following the date of the Equity Indicator. The Index will be in a new position effective on the second business day.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the S&P 500 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective at the close of business on the first business day following the date of the indicator(s). The Index will be in a new position effective on the second business day.
50/50 Indicator. When the S&P 500 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P 500 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the S&P 500 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the S&P 500 if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day.
T-Bill Indicator. When the S&P 500’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”) and the 50/50 Indicator has been triggered, the exposure of the Index will be 100% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the T-Bill Indicator. The Index will be in a new position effective on the second business day.
For example, if today is Wednesday and the S&P 500’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the S&P 500 to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the S&P 500 if the Equity Indicator is triggered, effective at the close of business on the first business day following the date of the indicator. The Index will be in a new position effective on the second business day. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is first triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the S&P 500 by tracking 3-Month US Treasury bills (instead of the S&P 500) when the S&P 500 is in a negative trend.
Special Indicator. In the event the S&P 500 closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the S&P 500 and 50% to 3-Month US Treasury bills. If the Index exposure is 50% S&P 500 and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

The S&P MidCap 400 measures the performance of mid-capitalization stocks in the United States.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become

50/50 Indicator. When the S&P MidCap 400 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P MidCap 400 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day.

The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the NASDAQ-100® Index (the “NASDAQ-100”), (ii) 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the NASDAQ-100 and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for the NASDAQ-100 is based on the total return version of the NASDAQ-100 and reflects the reinvestment of dividends paid by the securities in the NASDAQ-100. The Index is expected to be predominantly invested in the components of the NASDAQ-100 over most short- and long-term periods and is only expected to invest in 3-Month US Treasury bills from time to time in response to adverse market conditions as defined by the “50/50 Indicator” and “T-Bill Indicator” below.
The NASDAQ-100 Index includes approximately 100 of the largest non-financial securities listed on The NASDAQ Stock Market based on market capitalization. The NASDAQ-100 Index comprises securities of companies across major industry groups, including computer, biotechnology, healthcare, telecommunications and transportation. However, it does
not contain securities of financial companies, including investment companies. The NASDAQ-100 Index was developed by NASDAQ OMX. There is no minimum market capitalization requirement for inclusion in the NASDAQ-100 Index. Inclusion is determined based on the top 100 largest issuers based on market capitalization meeting all other eligibility requirements. As of June 30, 2025, the range of market capitalizations of companies in the NASDAQ-100 Index was approximately $18.4 billion to $3.9 trillion.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered. The Index will be in a new position effective at the close of business on the first business day.

When the NASDAQ-100 closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the NASDAQ-100, effective at the close of business on the first business day following the date of the Equity Indicator. The Index will be in a new position effective on the second business day.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s). The Index will be in a new position effective at the close of business on the first business day.
50/50 Indicator. When the NASDAQ-100 closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”) and the 50/50 Indicator has been triggered, the exposure of the Index will be 50% to the NASDAQ-100 and 50% to 3-Month US Treasury bills, effective at the close of business on the first business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the second business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the NASDAQ-100 and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.

Treasury bills. If the Index exposure is 50% NASDAQ-100 and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the FTSE Eurozone Index, (ii) 50% to the FTSE Eurozone Index and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of the FTSE Eurozone Index and its 200-business day historical simple moving average (the “200-day moving average”).

The FTSE Eurozone Index is a rules-based, float-adjusted, market capitalization-weighted index comprised of large- and mid-capitalization stocks providing coverage of the developed markets in the euro zone, including primarily France, Germany, Spain, the Netherlands, and Italy. The FTSE Eurozone Index is a subset of the FTSE Global Equity Index Series, which targets coverage of over 99% of investable market capitalization globally.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time.

Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index. As of June 30, 2025 the Index had significant exposure to the financials sector.

The S&P Developed Ex-U.S. LargeCap Index is a rules-based, float-adjusted, market capitalization-weighted index comprised of large-capitalization stocks providing coverage of the developed markets excluding the United States. The S&P Developed Ex-U.S. LargeCap Index is a subset of the S&P Global BMI, a comprehensive, rules-based index measuring global stock market performance.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered.
As of June 30, 2025, the Index was entirely invested in the S&P Developed Ex-U.S. LargeCap Index constituents.
Equity Indicator. When the S&P Developed Ex-U.S. LargeCap Index closes above its 200-day moving average for five consecutive business days (the “Equity Indicator”), the exposure of the Index will be 100% to the S&P Developed Ex-U.S. LargeCap Index, effective on the second business day following the date of the Equity Indicator.
Once the Equity Indicator has been triggered, the exposure of the Index will next change to either be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the T-Bill Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s).
50/50 Indicator. When the S&P Developed Ex-U.S. LargeCap Index closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills, effective on the second business day following the date of the 50/50 Indicator. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the S&P Developed Ex-U.S. LargeCap Index and 3-Month US Treasury bills depending on their respective performance until either the Equity Indicator or T-Bill Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the S&P Developed Ex-U.S. LargeCap Index if the Equity Indicator is triggered or 100% to 3-Month US Treasury bills if the T-Bill Indicator (described below) is triggered, effective on the second business day following the date of the indicator.
T-Bill Indicator. When the S&P Developed Ex-U.S. LargeCap Index’s 200-day moving average closes lower than its value from five business days earlier (the “T-Bill Indicator”), the exposure of the Index will be 100% to 3-Month US Treasury bills, effective on the second business day following the date of the T-Bill Indicator.
For example, if today is Wednesday and the S&P Developed Ex-U.S. LargeCap Index’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bill Indicator is triggered. Unlike the operation of the Equity Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bill Indicator has been triggered; rather, the T-Bill Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the S&P Developed Ex-U.S. LargeCap Index to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Equity Indicator.
Once the T-Bill Indicator has been triggered, the exposure of the Index will next change to be 100% to the S&P Developed Ex-U.S. LargeCap Index if the Equity Indicator is triggered, effective on the second business day following the date of the indicator. Once the T-Bill Indicator has been triggered, the Index will not return to its 50/50 position unless the Equity Indicator is first triggered, followed by the 50/50 Indicator being triggered.
The Index aims to mitigate, to some extent, the volatility of the S&P Developed Ex-U.S. LargeCap Index by tracking 3-Month US Treasury bills (instead of the S&P Developed Ex-U.S. LargeCap Index) when the S&P Developed Ex-U.S. LargeCap Index is in a negative trend.
Special Indicator. In the event the S&P Developed Ex-U.S. LargeCap Index closes 20% below its 200-day moving average, the Index will change exposures effective at the end of the following business day to be 50% to the S&P Developed Ex-U.S. LargeCap Index and 50% to 3-Month US Treasury bills. If the Index exposure is 50% Developed Ex-U.S. LargeCap Index and 50% 3-Month U.S. Treasury Bills before the Special Indicator, no rebalance is needed. This new exposure will continue until the Equity Indicator is triggered.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better. The Fund’s assets may include investments denominated in non-U.S. currencies.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
At times, the Fund may have a portfolio turnover rate substantially greater than 100%.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure to one of the following positions: (i) 100% to the iBoxx® USD Liquid High Yield Index, (ii) 50% to the iBoxx USD Liquid High Yield Index and 50% to the iBoxx® USD Treasuries 7-10 Year Index or (iii) 100% to iBoxx USD Treasuries 7-10 Year Index, depending on the “Risk Ratio,” described below.
The iBoxx USD Liquid High Yield Index is designed to track the performance of U.S. dollar-denominated, high-yield corporate bonds issued in the U.S. The iBoxx USD Treasuries 7-10 Year Index is designed to measure the performance of U.S. Treasury bonds maturing in 7 to 10 years. The Index uses a “Risk Ratio” to signal a change in the position of the Index. The Risk Ratio is calculated by dividing the value of the iBoxx USD Liquid High Yield Index by the value of the iBoxx USD Treasuries 7-10 Year Index.
The Index, and consequently the Fund, may stay in any of its three possible positions for an extended period of time. As described below, the Index will change its position based on the following indicators, and each change will become
effective by the close of business on the sixth business day after the indicator for the change is triggered. The Index will be in a new position effective on the seventh business day.
High Yield Indicator. When the Risk Ratio closes above its 100-day historical simple moving average (the “100-day moving average”) for five consecutive business days (the “High Yield Indicator”), the exposure of the Index will be 100% to the iBoxx USD Liquid High Yield Index, effective by the close of business on the sixth business day following the date of the High Yield Indicator. The Index will be in a new position effective on the seventh business day.
Once the High Yield Indicator has been triggered, the exposure of the Index will next change to either be 50% to the iBoxx USD Liquid High Yield Index and 50% iBoxx USD Treasuries 7-10 Year Index if the 50/50 Indicator (described below) is triggered or 100% to iBoxx USD Treasuries 7-10 Year Index if both the 50/50 Indicator and the Treasury Bond (“T-Bond”) Indicator (described below) are triggered simultaneously, effective by the close of business on the sixth business day following the date of the High Yield Indicator. The Index will be in a new position effective on the seventh business day.
50/50 Indicator. When the Risk Ratio closes below its 100-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Index will be 50% to the iBoxx USD Liquid High Yield Index and 50% iBoxx USD Treasuries 7-10 Year Index, effective by the close of business on the sixth business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the seventh business day. Following the effectiveness of the 50/50 Indicator, the exposure of the Index may be greater than or less than 50% with respect to the iBoxx USD Liquid High Yield Index and iBoxx USD Treasuries 7-10 Year Index depending on their respective performance until either the High Yield Indicator or T-Bond Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Index will next change to either be 100% to the iBoxx USD Liquid High Yield Index if the High Yield Indicator is triggered or 100% to iBoxx USD Treasuries 7-10 Year Index if the T-Bond Indicator (described below) is triggered, effective by the close of business on the sixth business day following the date of the 50/50 Indicator. The Index will be in a new position effective on the seventh business day.
T-Bond Indicator. When the Risk Ratio’s 100-day moving average closes lower than its value from five business days earlier (the “T-Bond Indicator”), the exposure of the Index will be 100% to iBoxx USD Treasuries 7-10 Year Index, effective by the close of business on the sixth business day following the date of the T-Bond Indicator. The Index will be in a new position effective on the seventh business day.
For example, if today is Wednesday and the Risk Ratio 100-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the T-Bond Indicator is triggered. Unlike the operation of the High Yield Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the T-Bond Indicator has been triggered; rather, the T-Bond Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Index will not move directly from 100% exposure to the iBoxx USD Liquid High Yield Index to 100% exposure to iBoxx USD Treasuries 7-10 Year Index unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the High Yield Indicator.
Once the T-Bond Indicator has been triggered, the exposure of the Index will next change to be 100% to the iBoxx USD Liquid High Yield Index if the High Yield Indicator is triggered, effective by the close of business on the sixth business day following the date of the indicator. The Index will be in a new position effective on the seventh business day. Once the T-Bond Indicator has been triggered, the Index will not return to its 50/50 position unless the High Yield Indicator is first triggered, followed by the 50/50 Indicator being triggered.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s net assets, plus borrowings for investment purposes, will be invested in bonds denominated in U.S. dollars. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole. However, the Fund may use a “replication” strategy to achieve its investment objective, meaning it will
invest in all of the component securities of the Index in the same approximate proportion as in the Index, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index does not involve practical difficulties or substantial costs).
The Fund generally may invest up to 20% of its total assets (exclusive of any collateral held from securities lending) in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).

The Index
The Fund of Funds Index uses an objective, rules-based approach to construct a portfolio that, as of each quarterly rebalance, is composed of the ETFs listed in the following table, each advised by the Adviser (collectively, the “Trendpilot® ETFs”). Each of the Trendpilot® ETFs is an index-based ETF that seeks to track the total return performance, before fees and expenses, of the underlying index listed in the following table (collectively, the “Trendpilot® Indexes”).
Each Trendpilot® Index other than the Pacer Trendpilot® US Bond Index (collectively, the “Trendpilot® Equity Indexes”) uses an objective, rules-based methodology to implement a systematic trend-following strategy that directs exposure (i) 100% to the “Underlying Component” specified in the table below, (ii) 50% to the applicable Underlying Component and 50% to 3-Month US Treasury bills, or (iii) 100% to 3-Month US Treasury bills, depending on the relative performance of
the Underlying Component and its 200-business day historical simple moving average (the “200-day moving average”). The calculation of the 200-day moving average for each Underlying Component is based on the total return version of such Underlying Component and reflects the reinvestment of dividends paid by the securities in such Underlying Component.

The Trendpilot® Indexes
Each Trendpilot® Equity Index uses a systematic trend following strategy that directs the Trendpilot® Equity Index’s exposure to either the applicable Underlying Component, 50% to the applicable Underlying Component and 50% to 3-Month US Treasury bills, or 100% to 3-Month US Treasury bills and may stay in any of its three possible positions for an extended period of time. The Trendpilot® Bond Index uses a systematic trend following strategy that directs the Trendpilot® Bond Index’s exposure to either the applicable Underlying Component, 50% to the applicable Underlying Component and 50% to the iBoxx USD Treasuries 7-10 Year Index, or 100% to the iBoxx USD Treasuries 7-10 Year Index and may stay in any of its three possible positions for an extended period of time. As described below, each Trendpilot® Index will change its position based on the following indicators, and each change will become effective on the second business day after the indicator for the change is triggered.
Underlying Component Indicator. When the applicable Underlying Component for the Trendpilot® Equity Indexes closes above its 200-day moving average for five consecutive business days (the “Underlying Component Indicator” for such indexes), the exposure of the applicable Trendpilot® Index will be 100% to the Underlying Component, effective on the second business following the date of the Underlying Component Indicator.
Once the Underlying Component Indicator has been triggered, the exposure of the applicable Trendpilot® Equity Index will next change to either be 50% to the Underlying Component and 50% to 3-Month US Treasury bills if the 50/50 Indicator (described below) is triggered or 100% to 3-Month US Treasury bills if both the 50/50 Indicator and the Treasury Indicator (described below) are triggered simultaneously, effective on the second business day following the date of the indicator(s).
With respect to the Trendpilot® Bond Index, when the Risk Ratio closes above its 100-day historical simple moving average (the “100-day moving average”) for five consecutive business days (the “Underlying Component Indicator” for such index), the exposure of the Trendpilot® Bond Index will be 100% to the iBoxx USD Liquid High Yield Index, effective by the close of business on the sixth business day following the date of the Underlying Component Indicator.
Once the Underlying Component Indicator has been triggered, the exposure of the Trendpilot® Bond Index will next change to either be 50% to the iBoxx USD Liquid High Yield Index and 50% iBoxx USD Treasuries 7-10 Year Index if the 50/50 Indicator (described below) is triggered or 100% to iBoxx USD Treasuries 7-10 Year Index if both the 50/50 Indicator and the Treasury Indicator (described below) are triggered simultaneously, effective by the close of business on the sixth business day following the date of the Underlying Component Indicator.
50/50 Indicator. With respect to each Trendpilot® Equity Index, when the applicable Underlying Component closes below its 200-day moving average for five consecutive business days (the “50/50 Indicator” for such index), the exposure of the Trendpilot® Equity Index will be 50% to the Underlying Component and 50% to 3-Month US Treasury bills, effective on the second business day following the date of the 50/50 Indicator (“50/50 Exposure”). Following the effectiveness of the 50/50 Indicator, the exposure of the Trendpilot® Equity Index may be greater than or less than 50%
with respect to the Underlying Component and 3-Month US Treasury bills depending on their respective performance until either the Underlying Component Indicator or Treasury Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Trendpilot® Equity Index will next change to either be 100% to the Underlying Component if the Underlying Component Indicator is triggered or 100% to 3-Month US Treasury bills if the Treasury Indicator (described below) is triggered, effective on the second business day following the date of the indicator.
With respect to each Trendpilot® Bond Index, when the Risk Ratio closes below its 100-day moving average for five consecutive business days (the “50/50 Indicator”), the exposure of the Trendpilot® Bond Index will be 50% to the iBoxx USD Liquid High Yield Index and 50% iBoxx USD Treasuries 7-10 Year Index, effective by the close of business on the sixth business day following the date of the 50/50 Indicator. Following the effectiveness of the 50/50 Indicator, the exposure of the Trendpilot® Bond Index may be greater than or less than 50% with respect to the iBoxx USD Liquid High Yield Index and iBoxx USD Treasuries 7-10 Year Index depending on their respective performance until either the Underlying Component Indicator or Treasury Indicator (described below) is triggered.
Once the 50/50 Indicator has been triggered, the exposure of the Trendpilot® Bond Index will next change to either be 100% to the iBoxx USD Liquid High Yield Index if the Underlying Component Indicator is triggered or 100% to iBoxx USD Treasuries 7-10 Year Index if the Treasury Indicator (described below) is triggered, effective by the close of business on the sixth business day following the date of the 50/50 Indicator.
Treasury Indicator. With respect to each Trendpilot® Equity Index, when the applicable Underlying Component’s 200-day moving average closes lower than its value from five business days earlier (the “Treasury Indicator” for such index), the exposure of the Trendpilot® Equity Index will be 100% to 3-Month US Treasury bills, effective on the second business day following the date of the Treasury Indicator.
For example, if today is Wednesday and the applicable Underlying Component’s 200-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the Treasury Indicator is triggered. Unlike the operation of the Underlying Component Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the Treasury Indicator has been triggered; rather, the Treasury Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Trendpilot® Equity Index will not move directly from 100% exposure to the Underlying Component to 100% exposure to 3-Month US Treasury bills unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Underlying Component Indicator.
With respect to the Trendpilot® Bond Index, when the Risk Ratio’s 100-day moving average closes lower than its value from five business days earlier (the “Treasury Indicator” for such index), the exposure of the Trendpilot® Bond Index will be 100% to iBoxx USD Treasuries 7-10 Year Index, effective by the close of business on the sixth business day following the date of the Treasury Indicator.
For example, if today is Wednesday and the Risk Ratio 100-day moving average closes lower than it did on the fifth preceding business day (Wednesday of the preceding week), the Treasury Indicator is triggered. Unlike the operation of the Underlying Component Indicator and 50/50 Indicator, the closing values on the days in between today and the fifth preceding business day do not affect whether the Treasury Indicator has been triggered; rather, the Treasury Indicator simply compares today’s closing value to the closing value five business days earlier. However, the Trendpilot® Bond Index will not move directly from 100% exposure to the iBoxx USD Liquid High Yield Index to 100% exposure to iBoxx USD Treasuries 7-10 Year Index unless the 50/50 Indicator was simultaneously triggered following the most recent triggering of the Underlying Component Indicator.
Once the Treasury Indicator has been triggered, the exposure of the Trendpilot® Index will next change to be 100% to the Underlying Component if the Underlying Component Indicator is triggered, effective on the second business day following the date of the indicator. Once the Treasury Indicator has been triggered, the Trendpilot® Index will not return to its 50/50 position unless the Underlying Component Indicator is first triggered, followed by the 50/50 Indicator being triggered.
Each Trendpilot® Index aims to mitigate, to some extent, the volatility of the Underlying Component by tracking 3-Month US Treasury bills or the iBoxx USD Treasuries 7-10 Year Index (instead of the Underlying Component), as applicable, when the applicable Underlying Component is in a negative trend. Because the Underlying Component Indicator, 50/50 Indicator, and Treasury Indicator (collectively, the “Exposure Indicators”) for each Trendpilot® Index operate independent
of the Exposure Indicators for each other Trendpilot® Index, the Fund of Funds Index may reflect Underlying Component exposure for each Trendpilot® ETF, a mix of Underlying Component exposures and 3-Month US Treasury bills, or entirely 3-Month US Treasury bills for short or long periods of time. When the 50/50 Indicator or Treasury Indicator has been triggered for a particular Trendpilot® ETF, the Fund of Funds Index will have reduced or no exposure, respectively, to the applicable Trendpilot® ETF’s Underlying Component.
Special Indicator. For each Trendpilot® Equity Index, in the event the Underlying Component closes 20% above or 20% below its 200-day simple moving average, the Trendpilot® Equity Index will change exposures effective at the end of the following business day to its 50/50 Exposure. This new exposure (the “Special Exposure”) will continue until the applicable Underlying Component Indicator, 50/50 Indicator, or Treasury Indicator is triggered.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Fund of Funds Index (i.e., the Trendpilot® ETFs). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Fund of Funds Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

Strategy [Heading] Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (“IDG” or the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to provide exposure to large and mid-capitalization U.S. companies with high free cash flow yields. Companies with high free cash flow yields are commonly referred to as “cash cows.”
The initial index universe is derived from the component companies of the Russell 1000® Index (excluding financial companies). Component companies of the initial universe are screened based on their market capitalization. The equity securities of the 400 companies with the highest market capitalization are included in the Index. Companies with negative average projected free cash flows or earnings are then removed from the Index universe.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents.
Free Cash Flow Yield: FCF / EV
The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The equity securities of the 100 companies with the highest free cash flow yield are included in the Index.
At the time of each rebalance of the Index, the companies included in the Index are weighted in proportion to their trailing twelve month free cash flow, and weightings are capped at the lesser of (i) 2% or (ii) a percentage equal to 5% of a company’s free float market capitalization, assuming Index market capitalization of $40 billion. The Index is reconstituted and rebalanced quarterly as of the close of business on the 3rd Friday of March, June, September, and December based on data as of the 1st Friday of the applicable rebalance month.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in U.S.-listed equity securities that are the component securities of the Index. The Fund defines “equity securities” to mean common stocks, and may include preferred stocks, rights, warrants, and depositary receipts. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The initial Index universe is derived from the component companies of the S&P United States SmallCap Index. Component companies of the initial universe are screened based on their 3-month average daily trading volume. The equity securities of the companies with a 3-month average daily trading volume in the top 75% of the initial universe are included in the Index. The remaining universe is then screened based on the average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies for which information on their projected free cash flows or earnings is not available will remain in the Index universe.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents.
Free Cash Flow Yield: FCF / EV
Companies with negative average projected free cash flows or earnings are removed from the Index universe. Equity securities that are not listed for trading on a U.S. securities exchange are excluded from the Index universe. Additionally, financial companies, other than real estate investment trusts (“REITs”), are excluded from the Index universe.
The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The equity securities of the 200 companies with the highest free cash flow yield are included in the Index.
At the time of each rebalance of the Index, the companies included in the Index are weighted in proportion to their trailing twelve month free cash flow, and weightings are capped at the lesser of (i) 2% or (ii) a percentage equal to 5% of a company’s free float market capitalization, assuming Index market capitalization of $20 billion. Weight above the 2% foregoing limitation is redistributed among the other Index constituents in proportion to their weights. As of June 30, 2025, the companies included in the Index had a market capitalization range of $244 million to $26 billion. From time to time, the Index may include more or less than 200 companies as a result of events such as acquisitions, spinoffs and other corporate actions. The Index is reconstituted and rebalanced quarterly as of the close of business on the 3rd Friday of March, June, September, and December based on data as of the 2nd Friday of the applicable rebalance month and will be completed over the next five days. As of June 30, 2025 the Index had significant exposure to the consumer discretionary sector.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s net assets (plus any borrowings for investment purposes) will be invested in U.S.-listed small-capitalization equity securities that are the component securities of the Index. The Fund considers “small-capitalization” companies to be companies within the S&P United States SmallCap Index. The Fund defines “equity securities” to mean common stocks, and may include preferred stocks, rights, warrants, and depositary receipts. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.”
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.

The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to provide exposure to global companies with high dividend yields backed by a high free cash flow yield.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Enterprise Value (EV): A company’s market capitalization plus its debt and minus its cash and cash equivalents.
Free Cash Flow Yield: FCF / EV
The initial index universe is derived from the component companies of the FTSE All-World Developed Large Cap Index. The initial universe of companies is screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years.
Companies with negative average projected free cash flows or earnings are removed from the Index universe. Additionally, financial companies, other than real estate investment trusts (“REITs”), are excluded from the Index universe.
The remaining companies are ranked by their free cash flow yield for the trailing twelve month period. The 300 companies with the highest free cash flow yield are then ranked by their dividend yield. The equity securities of the 100 companies with the highest dividend yield are included in the Index.
At the time of each rebalance of the Index, the companies included in the Index are weighted based on the aggregate amount of dividends distributed by each company for the trailing twelve month period, and weightings are capped at 2% of the weight of the Index for any individual company. The Index is reconstituted and rebalanced semi-annually as of the close of business on the 3rd Friday of June and December based on data as of the 1st Friday of the applicable rebalance month.

The Index
The Index uses a rules-based methodology that seeks to provide exposure to large-capitalization U.S. companies with above average free cash flow margins. Companies with above average free cash flow margins are commonly referred to as “cash cows.”
The initial Index universe is typically derived from the component companies of the Russell 1000 Index®. The initial universe of companies is typically screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies for which information on their projected free cash flows or earnings is not available will typically remain in the Index universe. A company’s projected free cash flows and earnings are typically determined by the Index Provider.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Sales: The value of what a company sold to its customers during a given period; also known as revenue.
Free Cash Flow Margin: FCF / Sales
Companies with negative average projected free cash flows or earnings are typically removed from the Index universe. Additionally, companies in the financial or real estate sectors are typically excluded from the Index universe.
The remaining companies are typically ranked by their free cash flow margin (defined as a company’s free cash flow divided by sales) for the trailing twelve month period. The equity securities of the 100 companies with the highest free cash flow margin are typically included in the Index. Companies included in the Index are typically weighted by their price momentum score and a company’s price momentum score is typically calculated on each of the reconstitution dates.
The weight of any individual company included in the Index is typically capped at 5%. Weight above the 5% limitation is typically redistributed among the other Index constituents in proportion to their weights. As of June 30 2025, the companies included in the Index had a market capitalization range of $3 billion to $3.9 trillion. As of June 30, 2025 the Index had significant exposure to the information technology sector. The Index is typically reconstituted and rebalanced quarterly as of the close of business on the third Friday of March, June, September, and December based on data as of the first Friday of the applicable rebalance month.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of large-capitalization companies (“large cap”) that are principally traded in the United States. The Fund considers a company to be a large-capitalization at the time of purchase if it was included in the Russell 1000 Index at any time within the prior 12 months. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to measure the performance of an equal weight portfolio of approximately 100 large- and mid-capitalization U.S. companies with a high percentage of foreign sales and high free cash flow growth. Free cash flow is a company’s cash flow from operations minus its capital expenditures.
Construction of the Index begins with an initial universe of the 200 companies across the S&P 900® Index (which is comprised of the S&P 500® Index (“S&P 500”) and S&P MidCap 400® Index (“S&P MidCap 400”)) that have the highest annual foreign sales as a percentage of total sales.
The 200 companies are then narrowed to the 100 companies with the highest change in free cash flow growth over the past five years, and those 100 companies are equally weighted to create the Index. As of June 30, 2025, the Index was made up of 100 companies and included significant allocations to companies in the information technology sector.
The Index is reconstituted and rebalanced to equal-weight quarterly.
From time to time, the Index may include more or less than 100 companies as a result of events such as acquisitions, spin-offs and other corporate actions.
The S&P 500 consists of approximately 500 leading U.S.-listed companies representing approximately 80% of the U.S. equity market capitalization. The S&P MidCap 400 measures the performance of mid-capitalization stocks in the United States.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Index uses an objective, rules-based methodology to measure the performance of an equal weight portfolio of approximately 100 large- and mid-capitalization non-U.S. companies with a high percentage of foreign sales and high free cash flow growth. Free cash flow is a company’s cash flow from operations minus its capital expenditures.
Construction of the Index begins with an initial universe of the 200 companies included in the FTSE Developed ex US Index that have the highest annual foreign sales as a percentage of total sales.
The 200 companies are then narrowed to the 100 companies with the highest free cash flow growth over the past five years, and those 100 companies are equally weighted to create the Index.
The Index is reconstituted and rebalanced to equal-weight semi-annually.
From time to time, the Index may include more or less than 100 companies as a result of events such as acquisitions, spin-offs and other corporate actions.
The FTSE Developed ex US Index is a rules-based, float-adjusted, market capitalization-weighted index comprised of large- and mid-capitalization stocks providing coverage of the developed markets in twenty-four non-U.S. countries. The FTSE Developed ex US Index is derived from the FTSE Global Equity Index Series, which covers 98% of the world’s investable market capitalization.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

The Index was developed by Pacer Advisers Inc. (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”), and measures the performance of the hotel, motel, and lodging real estate sectors of the U.S. equity market.
The Index
The Index is generally composed of the U.S.-listed equity securities of companies that derive at least 85% of their earnings or revenues from real estate operations in the hotel, motel, and lodging real estate sectors (“Eligible Companies”). At the time of each reconstitution of the Index, Eligible Companies with a market capitalization of more than $200 million and average daily traded volume of at least 10,000 shares are included in the Index (the “Index Constituents”). A significant portion of the Index is expected to be composed of real estate investment trusts (“REITs”). The real estate companies included in the Index may utilize leverage, and some may be highly leveraged. Additionally, such companies may include significant business operations outside of the United States.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) quarterly as of the close of business on the third Friday of March, June, September, and December. Index Constituents are weighted based on their free-float market capitalization (i.e., market capitalization based on the number of shares available to the public), subject to the following constraints as of the time of each reconstitution of the Index. Each Index
Constituent’s weight is capped at 15% and the sum of Index Constituents with weights greater than 4.5% cannot exceed 45% of the total Index weight. If the foregoing limits would be exceeded at the time of a reconstitution of the Index, the excess weight is proportionally redistributed to all Index Constituents with weights below such limits.

Strategy [Heading] Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”).
The Index
The Pacer Autopilot Hedged European Index uses an objective, rules-based methodology (i) to invest in the component stocks of the FTSE Eurozone Index and (ii) to apply a proprietary currency hedging strategy pursuant to which the Index will be short the euro and long the U.S. dollar during periods when the euro is trending weaker against the U.S. dollar. The component stocks of the FTSE Eurozone Index form the equity component of the Pacer Autopilot Hedged European Index. The Index’s proprietary currency hedging strategy is overlayed on top of the equity component.
Equity Exposure. The FTSE Eurozone Index is a rules-based, float-adjusted, market capitalization-weighted index comprised of large- and mid-capitalization stocks providing coverage of the developed markets in the euro zone, including primarily France, Germany, Spain, the Netherlands, and Italy. The FTSE Eurozone Index is derived from the FTSE Global Equity Index Series, which covers 98% of the world’s investable market capitalization.
Currency Hedging. During each period when the euro’s 20-day moving average is lower than its 130-day moving average, the Index will, in addition to its equity exposure, track 1-month forward currency contracts, rolled to each subsequent month as applicable, to offset the Index’s exposure to the euro with exposure to U.S. dollars (i.e., short the euro and long the U.S. dollar), known as being “currency hedged”. A forward currency contract is an agreement to buy or sell a specific currency at a future date at a price set at the time of the contract. During each period when the euro’s 20-day moving average is higher than its 130-day moving average, the Index will track only the equity exposure, known as being “currency unhedged”.
The Index may stay “currency hedged” or “currency unhedged” for short or extended periods of time.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
In tracking the Index when it is currency hedged, the Fund enters into forward currency contracts designed to offset the Fund’s exposure to the euro. The Fund hedges the euro to the U.S. dollar by selling euro currency forwards at the then-current one-month forward rate. The amount of forward contracts in the Fund is based on the aggregate exposure of the Fund and Index to the euro at the time the Index becomes currency hedged. While this approach is designed to minimize the adverse impact of currency fluctuations on Fund returns, this does not necessarily eliminate exposure to all adverse currency fluctuations. The return of the forward currency contracts may not perfectly offset the actual fluctuations of the euro relative to the U.S. dollar.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund will be considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Strategy [Heading] Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”). The Index utilizes a systematic risk management strategy that directs the Index’s exposure to U.S. equity securities, U.S. Treasury securities, or a mix of each.
The Index
The Index uses an objective, rules-based methodology to implement a trend-following strategy that directs some or all of the Index’s exposure to (i) U.S. equity securities or (ii) U.S. Treasury securities depending on the strength of the high-yield corporate (“junk”) bond market relative to U.S. Treasury bonds and the momentum of certain U.S. equity sectors or industries and of long-term U.S. Treasury bonds, as described below.
Exponential Moving Average: An exponential moving average (EMA) is a type of moving average that reacts faster to recent price changes than a simple moving average.
Exposure to Equities or Fixed Income
On the third-to-last business day of each month (the “Selection Date”), the Index will observe the ratio between the S&P U.S. High Yield Corporate Bond Index and the S&P U.S. Treasury Bond 7-10 Year Index (the “Risk Ratio”). The Risk Ratio relative to its 5-month exponential moving average determines whether the Index will be in Equity Mode or Fixed Income Exposure, each as described below, for the following month effective on the first day of such month. If the Risk
Ratio is at or above its 5-month exponential moving average, the Index will be in Equity Exposure for the following month. If the Risk Ratio is below its 5-month exponential moving average, the Index will be in Fixed Income Exposure for the following month.
Equity Exposure
If the Risk Ratio dictates that the Index will be in Equity Exposure for the following month, the Index will select the five U.S. equity market components (“Equity Components”) from the list below with the best performance. The performance of each Equity Component is updated quarterly as of the Selection Date in each March, June, September, and December, and is based on the total return for the 6-month period ending on such Selection Date.
S&P 500® Energy Sector Total Return Index
S&P 500® Materials Sector Total Return Index
S&P 500® Information Technology Sector Total Return Index
S&P 500® Industrials Sector Total Return Index
S&P 500® Financials Sector Total Return Index

S&P 500® Consumer Staples Sector Total Return Index
S&P Biotechnology Select Industry Total Return Index
S&P 500® Consumer Discretionary Sector Total Return Index
Dow Jones Internet Composite Index
Each of the five Equity Components selected will be equally weighted (i.e., 20% to each Equity Component). However, if the value of any of the Equity Components selected is below such Equity Component’s 7-month exponential moving average, the 20% allocation to each such Equity Component will instead be allocated to 3-month U.S. Treasury bills. For each Equity Component included in the Index, the individual equity securities of such Equity Component will be included in the Index holdings in the proportion they had as of the Selection Date. When all five Equity Components selected are included in the Index, the Index will be comprised of approximately 400 individual equity securities.
Fixed Income Exposure
If the Risk Ratio dictates that the Index will be in Fixed Income Exposure for the following month, the Index will be 100% allocated to the S&P U.S. Treasury Bond 20+ Year Total Return Index (the “20+ Year Index”). However, if the value of the 20+ Year Index is below its 7-month exponential moving average, the Index will instead be 100% allocated to 3-month U.S. Treasury bills.
The constituents identified as of the Selection Date will become effective on the first business day of the month following the Selection Date.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up (i) the component securities of the Index or (ii) ETFs that seek to track the performance of some or all of the component securities of the Index in the same approximate weight as such component securities. The Fund’s investments in the component securities of the Index will consist of equity and/or fixed income securities or other ETFs investing in such equity and/or fixed income securities. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index in the same approximate proportion as in the Index.
The Fund may invest in other ETFs whose holdings correspond to the holdings of an Equity Component when such Equity Component is included in the Index. Similarly, the Fund may invest in other ETFs whose holdings correspond to the holdings of the 20+ Year Index or are comprised of 3-month U.S. Treasury bills when such components are included in the Index.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by CFRA (the “Index Provider”), a leading independent investment research firm.
The Index
The Index uses an objective, rules-based methodology to track the performance of a semi-annual rotation of certain sectors within the S&P® Global 1200 Index (S&P Global 1200”). The S&P Global 1200 is a free-float weighted index that captures approximately 70% of the world market capitalization, including stocks in 30 countries and covering all 11 Global Industry Classification Standard (“GICS®”) sectors, six of which are eligible for inclusion in the Index as described below. The size of each region included in the S&P Global 1200 generally corresponds to the region’s relative size in the global equity market based on float- adjusted market values.
On the last business day of each April, the Index is equally weighted in the S&P Global 1200 Consumer Staples and Healthcare sectors. The Index holdings then float until the last business day of the following October, when the Index is reconstituted and rebalanced to an equal weighting in the S&P Global 1200 Consumer Discretionary, Industrials, Information Technology, and Materials sectors. The Index holdings then float until the last business day of the
following April (the next calendar year), when the Index is reconstituted and rebalanced back to an equal weighting in the S&P Global 1200 Consumer Staples and Healthcare sectors.

At the time of each reconstitution of the Index, the Index is equally weighted in the applicable S&P Global 1200 sectors. Within each sector allocation, the weight of each individual stock is identical to its proportion of the applicable sector weight in the S&P Global 1200. For example, on the last business day of each April, the Index is reconstituted to include the individual stock components of the S&P Global 1200 Consumer Staples and Healthcare sectors, and the sum of the weight of the individual stock components of the S&P Global 1200 Consumer Staples sector will equal the sum of the weight of the individual stock components of the S&P Global 1200 Healthcare sector.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) will be invested in the component securities of the Index and in investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts), or in one or more ETFs that track the performance of all or a portion of such component securities in the same approximate proportion as in the Fund’s underlying Index. The Fund’s investment adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by CFRA (the “Index Provider”), a leading independent investment research firm.
The Index
The Index uses an objective, rules-based methodology to track the performance of a semi-annual rotation of certain sectors within the S&P 500® Equal Weight Index (“EWI”). The S&P 500® EWI is an equal-weighted version of the S&P 500®, which measures the performance of the large-cap segment of the U.S. equity market. The S&P 500® EWI includes stocks covering all 11 Global Industry Classification Standard (“GICS®”) sectors, six of which are eligible for inclusion in the Index as described below.
On the last business day of each April, the Index is equally weighted in the S&P 500 EWI Consumer Staples and Healthcare sectors. The Index holdings then float until the last business day of the following October, when the Index is reconstituted and rebalanced to an equal weighting in the S&P 500 EWI Consumer Discretionary, Industrials, Information Technology, and Materials sectors. The Index holdings then float until the last business day of the following April (the next calendar year), when the Index is reconstituted and rebalanced back to an equal weighting in the S&P 500 EWI Consumer Staples and Healthcare sectors.

At the time of each reconstitution of the Index, the Index is equally weighted in the applicable S&P 500® EWI sectors. Within each sector allocation, the weight of each individual stock is identical to its proportion of the applicable sector weight in the S&P 500® EWI. For example, on the last business day of each April, the Index is reconstituted to include the individual stock components of the S&P 500 EWI Consumer Staples and Healthcare sectors, and the sum of the weight of the individual stock components of the S&P 500 EWI Consumer Staples sector will equal the sum of the weight of the individual stock components of the S&P 500 EWI Healthcare sector.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Fund’s underlying Index or in one or more ETFs that track the performance of all or a portion of such component securities in the same approximate proportion as in the Fund’s underlying Index. The Fund’s investment adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed by Lunt Capital Management, Inc. (“Lunt Capital” or the “Index Provider”).
The Index
The Index uses an objective, rules-based methodology to provide exposure to large-capitalization U.S. companies. The Index uses Lunt Capital’s proprietary relative strength methodology to rotate between the holdings of one of two sub-indices, the S&P 500 Low Volatility Index and the S&P 500 High Beta Index (each, a “Sub-Index,” and together, the “Sub-Indices”), that seek to identify the 100 components of the S&P 500 Index that most strongly exhibit a particular trait (e.g., low volatility or high beta). Each Sub-Index is composed of the 100 securities comprising the S&P 500 Index that most strongly exhibit the characteristic screened for by the Sub-Index. The S&P 500 is a free-float weighted index that measures the performance of the large-cap segment of the U.S. equity market. The S&P 500 includes approximately 500 leading companies and captures approximately 80% of the U.S. market capitalization. Accordingly, each Sub-Index is composed of large-capitalization equity securities. S&P Opco LLC (a subsidiary of S&P Dow Jones Indices, LLC) compiles, maintains, and calculates the S&P 500 Index and the Sub-Indices.
The S&P 500 Low Volatility Index is composed of the 100 securities comprising the S&P 500 Index that have exhibited the lowest realized volatility over the prior 12 months. Each stock comprising the S&P 500 Low Volatility Index is
weighted by the inverse of its volatility with the least volatile stocks receiving the highest weights. Volatility is a statistical measurement of the magnitude of price fluctuations in a stock’s price over time.
The S&P 500 High Beta Index is composed of the 100 securities comprising the S&P 500 Index that have exhibited the highest sensitivity to market movements, or “beta,” over the prior 12 months. The weight of each stock in the S&P 500 High Beta Index is proportionate to its beta, rather than to its market capitalization. Beta is a measure of relative risk and is the rate of change of a security’s price.
The Index utilizes Lunt Capital’s proprietary relative strength analysis in its attempt to determine which Sub-Index is likely to exhibit better price performance than the other Sub-Index. Pursuant to this methodology, the Index Provider calculates the “Risk Adjusted Score” for each Sub-Index. Each Sub-Index’s “Risk-Adjusted Score” is calculated using the Sub-Index’s standard deviation of returns over the prior 12 months. On the final trading day of each month, the Index Provider computes the relative strength of each Sub-Index by comparing each Sub-Index’s Risk-Adjusted Score. The Index Provider considers the Sub-Index with the higher Risk-Adjusted Score to have the higher relative strength. The Index is composed of the securities comprising the Sub-Index demonstrating the greater relative strength. The Index is reconstituted and rebalanced monthly, except when the Index methodology would not result in a change in the Sub-Index comprising the Index at such time.
The Fund’s Investment Strategy
The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended (the “1940 Act”). However, the Fund may become “non-diversified” solely as a result of a change in the relative market capitalization or index weighting of one or more constituents of the Index.
Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of large cap companies. The Fund considers a company to be a “large cap company” at the time of purchase if it was included in the S&P 500 at any time within the prior 12 months. The Fund’s investment adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The Index
The Index uses an objective, rules-based methodology to provide exposure to mid-capitalization U.S. companies. The Index uses Lunt Capital’s proprietary relative strength methodology to rotate between the holdings of the highest and lowest quintile components of four factor-based indices of the S&P MidCap 400 Index (each, a “Sub-Index,” and together, the “Sub-Indices”), that seek to identify the components of the S&P MidCap 400 Index that most strongly exhibit a particular factor.

Pacer Aristotle Pacific Floating Rate High Income ETF

Strategy [Heading] Principal Investment Strategies of the Fund
Strategy Narrative [Text Block]
Aristotle Pacific Capital, LLC (the “Sub-Adviser”) seeks to achieve the Fund’s investment objective by selecting a focused portfolio comprised primarily of income-producing adjustable rate securities.
Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in senior secured floating rate loans and other adjustable rate securities. Other adjustable rate securities will typically include collateralized loan obligations (“CLOs”), asset-backed securities (“ABS”), and commercial mortgage backed securities (“CMBS”) (collectively, “Adjustable Rate Securities”). The Fund is expected to invest primarily in loans and Adjustable Rate Securities that are rated below investment grade (i.e., high yield securities, sometimes called “junk bonds” or non-investment grade securities) or, if unrated, of comparable quality as determined by the Sub-Adviser, each at the time of purchase.
The Fund may invest in U.S.-dollar denominated senior floating rate loans and Adjustable Rate Securities of domestic and foreign issuers. Senior floating rate loans are debt instruments that may have a right to payment that is senior to most other debts of borrowers. Borrowers may include corporations, partnerships and other entities that operate in a variety of industries and geographic regions, which may from time to time prepay their loan obligations in response, for example, to changes in interest rates. Senior loans in which the Fund may invest include secured and unsecured loans. Generally, secured floating rate loans are secured by specific assets of the borrower. An adjustable rate security includes any fixed income security that requires periodic changes in its interest rate based upon changes in a recognized index interest rate or
another method of determining prevailing interest rates. The Fund invests in various types of ABS, such as auto loan and student loan ABS. The Fund is actively managed.
The Fund may invest up to 20% of its assets in certain other types of debt instruments or securities, including corporate bonds (including floating rate investment grade bonds) and secured or unsecured second lien floating rate loans. Second lien loans generally are second in line behind senior loans in terms of prepayment priority with respect to pledged collateral and therefore have a lower credit quality as compared to senior loans but may produce a higher yield to compensate for the additional risk.
The secondary market on which high yield securities are traded may be less liquid than the market for investment-grade securities. Less liquidity in the secondary trading market could adversely affect the ability of the Fund to sell a high yield security or the price at which the Fund could sell a high yield security, and could adversely affect the daily NAV of Fund shares. When secondary markets for high yield securities are less liquid than the market for investment-grade securities, it may be more difficult to value the securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation because there is less reliable, objective data available. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments, as such term is defined by Rule 22e-4 under the Investment Company Act of 1940, as amended (the “1940 Act”).
When the Sub-Adviser believes that current market, economic, political or other conditions are unsuitable and would impair the pursuit of the Fund’s investment objectives, the Fund may invest some or all of its assets in cash or cash equivalents, including but not limited to obligations of the U.S. government, money market fund shares, commercial paper, certificates of deposit and/or bankers acceptances, as well as other interest bearing or discount obligations or debt instruments that carry an investment grade rating by a national rating agency. When the Fund takes a temporary defensive position, the Fund may not achieve its investment objectives. The Fund may invest from time to time more heavily in one or more sectors of the economy than in other sectors.

The Index is a rules-based index that consists of globally-listed stocks and depositary receipts of companies that, at the time of being added to the Index, derive at least 50% of their revenues from one of the following activities related to the use, manipulation, transmission, or storage of data (i.e., information that is stored in a digital or electronic format) and the ancillary services that enable these processes (i.e., services that enable companies to use, manipulate, transmit, or store data): electrical equipment and component manufacturing; automatic environmental control or heating and cooling equipment; computer storage device manufacturing; computer systems design services; computer equipment or telephone equipment manufacturing; custom computer programming or record reproducing services; data processing and hosting services; software publishing; semiconductor manufacturing; wireless communications equipment manufacturing; communication and energy wire or wiring device manufacturing or producers of raw materials; cybersecurity systems and
data protection services; power and distribution transformer manufacturing; satellite and digital telecommunications; electrical equipment component manufacturing; industrial value manufacturing; commercial machinery manufacturing; instruments used for measuring, displaying, and controlling industrial process variables (e.g., instruments used for testing electricity and glass thermometers for non-medical uses); computer facilities management services; or electrical equipment or wiring supplies wholesalers (collectively, “Data and Digital Revolution”), as determined by the Index Provider.
To be added to the Index, an Index component must have a market capitalization greater than or equal to US$1 billion, have a three-month average-daily-value-traded of at least US$2 million, and must be a publicly-traded equity security that is the primary listing security on a major stock exchange (collectively, the Index’s “Investibility Requirements”). The Index may include companies of any market capitalization that meets the Investibility Requirements, but has significant exposure to large- and mid-capitalization companies.
Data and Digital Revolution companies include companies in the Information Technology Sector and the Industrials Sector, as categorized by a third-party classification system. Index constituents meeting the Investibility Requirements are screened by the Index Provider from the universe of globally-listed stocks based primarily on descriptions of a company’s business activities in regulatory filings (e.g., financial statements, annual reports, investor presentations), analyst reports, a company’s website, and industry-specific trade publications.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) on an annual basis as of the close of business on the last trading day in April. Index Constituents are weighted based on their free-float market capitalization (i.e., market capitalization based on the number of shares available to the public), subject to the following constraints as of the time of each reconstitution of the Index. Each Index Constituent’s weight is capped at 10% and the sum of Index Constituents with weights greater than 4.5% cannot exceed 45% of the total Index weight. If the foregoing limits would be exceeded at the time of a reconstitution of the Index, the excess weight is proportionally redistributed to all Index Constituents with weights below such limits.
As of June 30, 2025, the Index was composed of 73 constituents, 7 of which were listed on a non-U.S. exchange.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to have significant exposure to companies in the Industrials and Information Technology Sectors. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

MSCI World Ricardo Comparative Advantage Select Index
The Index is a rules-based index that aims to represent the performance of the securities from a set of countries which have the highest active weight in each of the twenty-five GICS® Industry Groups as measured against the MSCI World Index (the “Parent Index”). GICS® Industry Groups comprise one of the four tiers of GICS®, a hierarchical industry classification system maintained by MSCI and S&P Dow Jones Indices. Securities in the eligible universe of the constituent companies of the Parent Index are screened to identify the country with the highest active country weight in each GICS® Industry Group. Securities with a three-month average daily traded value greater than or equal to $5 million are eligible for inclusion in the Index. The securities that meet the screening criteria are grouped by country and each group is weighted by the product of their aggregated free-float adjusted market capitalization and the corresponding country’s gross domestic product. Additionally, the constituent security weights are capped at 5% to mitigate concentration risk in the Index. In case it is not feasible to cap the security weights at 5%, the capping will be relaxed to 10% in steps of 1%.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) on a quarterly basis, coinciding with the February, May, August and November index reviews of the Parent Index.

In addition, the Index may have significant exposure to one or more countries at any given time. As of June 30, 2025, the Index had significant exposure to companies in the United States. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Strategy Narrative [Text Block]
The Fund employs a “passive management” (or indexing) investment approach designed to track the total return performance, before fees and expenses, of the Index. The Index is based on a proprietary methodology developed and maintained by Index Design Group (the “Index Provider” or “IDG”), an affiliate of Pacer Advisors, Inc., the Fund’s investment adviser (the “Adviser”). Solactive AG serves as the calculation agent for the Index.
The Index
The Index uses a rules-based methodology that seeks to provide exposure to large-capitalization U.S. companies with above average free cash flow margins. Companies with above average free cash flow margins are commonly referred to as “cash cows.”
The initial Index universe is typically derived from the component companies of the Nasdaq-100 Index® (the “Nasdaq-100”). The initial universe of companies is typically screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years. Companies for which information on their projected free cash flows or earnings is not available will typically remain in the Index universe. A company’s projected free cash flows and earnings are typically determined by the Index Provider. Companies with negative average projected free cash flows or earnings are typically removed from the Index universe. Additionally, companies in the financial or real estate sectors, real estate investment trusts, special purpose acquisition companies and when-issued securities are typically excluded from the Index universe.
Free Cash Flow (FCF): A company’s cash flow from operations minus capital expenditures.
Sales: The value of what a company sold to its customers during a given period; also known as revenue.
Free Cash Flow Margin: FCF / Sales
The remaining companies are typically ranked by their free cash flow margin (defined as a company's free cash flow divided by sales) for the trailing twelve month period. The equity securities of the 50 companies with the highest free cash flow margin are typically included in the Index. Companies included in the Index are typically weighted by their price momentum score and a company’s price momentum score is typically calculated on each of the reconstitution dates.
The weight of any individual company included in the Index is typically capped at 5%. Weight above the 5% limitation is typically redistributed among the other Index constituents in proportion to their weights. As of June 30, 2025, the companies included in the Index had a market capitalization range of $18.4 billion to $3.9 trillion. As of June 30, 2025, the Index had significant exposure to the information technology sector. The Index is typically reconstituted and rebalanced quarterly as of the close of business on the third Friday of February, May, August and November based on data as of the first Friday of the applicable rebalance month.
The Nasdaq-100 is designed to measure the performance of 100 of the largest non-financial companies by modified market capitalization listed on the Nasdaq Global Select Market or the Nasdaq Global Market. The Nasdaq-100 generally includes securities issued by U.S. and non-U.S. issuers, including american depositary receipts (“ADRs”), common stocks, ordinary shares and tracking stocks; real estate investment trusts are not eligible for index inclusion.
The Fund’s Investment Strategy
Under normal circumstances, the Fund will seek to invest at least 80% of the Fund’s total assets (exclusive of collateral held from securities lending) in growth securities (i.e., the component securities of the Index). The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it will invest in all of the component securities of the Index.
To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Index, and consequently the Fund, is expected to have significant exposure to companies in the Information Technology Sector. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Nasdaq International Patent Leaders Index
The Index is a rules-based full market capitalization-weighted index that consists of companies from the Nasdaq Global Ex United States Large Mid Cap Index with the most valuable patent portfolios.
The Index universe consists of all issuers from the Nasdaq Global Ex United States Large Mid Cap Index. Issuers of all eligible securities are ranked by the patent values as determined by IPR Strategies. IPR Strategies is an independent data provider that seeks to determine the potential value of an issuer by quantifying such issuer’s intangible assets, such as its intellectual property and research and development activities, as represented by patents held by such issuer. To value a company’s patent portfolio, IPR Strategies utilizes a proprietary valuation model that takes into account patent data collected from multiple sources, including patent offices and corporate filings, as well as a variety of other economic data, including actual values from previously traded patents. The model determines a “patent value estimate,” which represents the estimated dollar value of an issuer’s portfolio of patents. The 100 issuers with the largest patent values as determined by IPR Strategies are selected for inclusion in the Index.
The Index is reconstituted and rebalanced (i.e., companies are added or deleted and weights are reset based on Index rules) semi-annually in June and December.
As of June 30, 2025, the Index was composed of 100 constituents. The Index was established on June 24, 2024 and is owned and maintained by the Index Provider.
