UNDERSTANDING FUND EXPENSES

As a shareholder, you incur two types of costs: (1) transaction costs, which may include creation and redemption fees and brokerage charges, and (2) ongoing costs, including management fees and other fund expenses. These ongoing costs are described in more detail in the Fund’s prospectus. The following examples are intended to help you understand the ongoing costs of investing in the Fund and help you compare these with the ongoing costs of investing in other funds.

The first line in the table shows the actual account values and actual Fund expenses you would have paid on a $1,000 investment in the Fund from January 1, 2023 through June 30, 2023. To estimate the expenses you paid over the period, simply divide your account value by $1,000 (for example $8,600 account value divided by $1,000 = 8.60) and multiply the result by the number in the Expenses Paid During Period column as shown below for your class.

The second line in the table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratios and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid on your investment for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown reflect ongoing costs only, and do not include any transaction costs, such as brokerage commissions on purchases and sales of Fund shares. Therefore, the second line in the table is useful in comparing ongoing costs only, and will not help you determine the relative costs of owning different funds. If transaction costs were included, total costs would be higher.

The chart above represents historical performance of a hypothetical investment of $1,000 in the fund for the most recent six-month period. Past performance does not guarantee future results. This chart does not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

BOARD APPROVAL OF THE INITIAL ADVISORY AND SUB-ADVISORY AGREEMENTS FOR THE NATIXIS LOOMIS SAYLES FOCUSED GROWTH ETF

The Investment Company Act of 1940, as amended (the “1940 Act”), requires that both the full Board of Trustees of the Trust (the “Board”) and a majority of the Trustees who are not “interested persons” (as defined in the 1940 Act) of the Trust (the “Independent Trustees”), voting separately, initially approve any new investment advisory and sub-advisory agreements for a registered investment company, including a newly formed fund such as the Natixis Loomis Sayles Focused Growth ETF (the “Fund”). The Trustees, including the Independent Trustees, unanimously approved, for an initial two-year term, the proposed investment advisory and sub-advisory agreements (together, the “Agreements”) for the Fund at a meeting held on June 7-8, 2023.

In connection with this review, Fund management and other representatives of the Fund’s adviser, Natixis Advisors, LLC (the “Adviser”), and the Fund’s sub-adviser, Loomis, Sayles & Company, L.P. (the “Subadviser”) provided to the Trustees materials including, among other items, information regarding (i) the Fund’s investment objective, strategies and risks, (ii) the proposed advisory and sub-advisory fees and other expenses to be charged to the Fund, including information comparing the Fund’s expenses to those of peer groups and categories of funds and information on fees charged to other funds advised by the Adviser and Subadviser and the proposed expense cap, (iii) the size, education and experience of the Adviser’s and Subadviser’s respective investment staffs and the investment strategies proposed to be used in managing the Fund, (iv) proposed arrangements for the distribution and trading of the Fund’s shares, (v) information about the Adviser’s and Subadviser’s historical performance, (vi) information about the unique attributes of the Fund as a semi-transparent, actively managed ETF as compared with traditional ETFs and the policies and procedures being implemented in respect of those attributes, and (vi) the general economic outlook with particular emphasis on the asset management industry.

The Trustees also considered the fact that they oversee other funds advised by the Adviser and Subadviser, including the other semi-transparent, actively managed ETFs in the fund complex, as well as information about the Adviser and Subadviser they had received in connection with their oversight of those other funds. Because the Fund is newly formed and had not commenced operations at the time of the Trustees’ review, certain information, including data relating to Fund performance, was not available, and therefore could not be considered by the Trustees. Throughout the process, the Trustees were afforded the opportunity to ask questions of, and request additional materials from, the Adviser and the Subadviser. The Independent Trustees also met separately with independent legal counsel outside the presence of Adviser and Subadviser personnel.

In considering whether to initially approve the Agreements, the Board, including the Independent Trustees, did not identify any single factor as determinative. Individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. Matters considered by the Trustees, including the Independent Trustees, in connection with their approval of the Agreements included, but were not limited to, the factors listed below.

The nature, extent and quality of the services to be provided to the Fund under the Agreements. The Trustees considered the nature, extent and quality of the services to be provided by the Adviser, the Subadviser and the Adviser’s affiliates to the Fund, which include advisory and non-advisory services directed to the needs and operations of the Fund as a semi-transparent, actively managed ETF. The Trustees also considered the resources to be dedicated to the Fund by the Adviser, the Subadviser and the Adviser’s affiliates. The Trustees considered their experience with other funds advised or sub-advised by the Adviser and the Subadviser, including other semi-transparent, actively managed ETFs in the fund complex, as well as the affiliation between the Adviser and Natixis Investment Managers, LLC (“Natixis Investment Managers”), whose affiliates provide investment advisory services to other funds in the same family of funds. In this regard, the Trustees considered not only the advisory and sub-advisory services proposed to be provided by the Adviser and the Subadviser to the Fund, but also the monitoring and oversight services proposed to be provided by the Adviser. They also considered the administrative and shareholder services proposed to be provided by the Adviser and its affiliates to the Fund. The Trustees also considered the unique services required to operate the Fund’s semi-transparent structure, including the additional systems, processes and portfolio management oversight structures needed to ensure proper creation and disclosure of the proxy portfolio for such funds.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the Agreements, that the scope of the services to be provided to the Fund under the Agreements seemed consistent with the Fund’s operational requirements, and that the Adviser and the Subadviser had the capabilities, resources and personnel necessary to provide the advisory and sub-advisory services that would be required by the Fund. The Trustees determined that the nature, extent and quality of services proposed to be provided under the Agreements supported approval of the Agreements.

Investment performance of the Fund, the Adviser and the Subadviser. Because the Fund had not yet commenced operations, performance information for the Fund was not considered; however, the Board considered the performance of other funds and accounts managed by the Adviser and the Subadviser, including the other semi-transparent, actively managed ETFs in the fund complex.

The Trustees also considered the Adviser’s and the Subadviser’s performance and reputation generally, the performance of the fund family generally, and the historical responsiveness of the Adviser and Subadviser to Trustee concerns about performance and the willingness of the Adviser and Subadviser to take steps intended to improve performance.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the Agreements, that these relevant factors supported approval of the Agreements.

The costs of the services to be provided by the Adviser and the profits to be realized by the Adviser and its affiliates from their respective relationships with the Fund. Although the Fund had not yet commenced operations at the time of the Trustees’ review of the Agreements, the Trustees reviewed information comparing the proposed advisory and sub-advisory fees and estimated total expenses of the Fund with the fees and expenses of comparable funds identified by the Adviser, including information about how those funds were selected and information about differences in such fees. In evaluating the Fund’s proposed advisory and sub-advisory fees, the Trustees also took into account the demands, complexity and quality of the investment management services to be provided to the Fund, including the additional responsibilities of the Adviser and the Subadviser and their affiliates in managing a semi-transparent, actively managed ETF. The Trustees also noted that the Fund would have an expense cap in place. In addition, the Trustees considered information regarding the administrative fees to be paid by the Fund to the Adviser.

Because the Fund had not yet commenced operations, historical profitability information with respect to the Fund was not considered. However, the Trustees noted the information provided in court cases in which adviser profitability was an issue, the estimated expense level of the Fund, and that the Fund would be subject to an expense cap.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the Agreements, that the advisory and sub-advisory fees and expenses proposed to be charged to the Fund were fair and reasonable, and that the anticipated costs of these services generally and the anticipated profitability of the Adviser and its affiliates in respect of their relationships with the Fund supported the approval of the Agreements.

Economies of scale. The Trustees considered the extent to which the Adviser and the Subadviser may realize economies of scale in the provision of services by the Adviser and the Subadviser, respectively, and whether those economies could be shared with the Fund through breakpoints in its investment advisory and sub-advisory fees or other means, such as an expense cap. The Trustees noted that the Fund will be subject to an expense cap. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the Agreements, that the extent to which economies of scale might be shared with the Fund supported the approval of the Agreements.

The Trustees also considered other factors, which included but were not limited to the following:

Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel, the Trustees, including the Independent Trustees, concluded that the Agreements should be approved.

BOARD APPROVAL OF THE EXISTING ADVISORY AND SUB-ADVISORY AGREEMENTS

The Board of Trustees of the Trust (the “Board”), including the Independent Trustees, considers matters bearing on each Fund’s advisory agreement and sub-advisory agreement (collectively, the “Agreements”), at most of its meetings throughout the year. Each year, usually in the spring, the Contract Review Committee of the Board meets to review the Agreements to determine whether to recommend that the full Board approve the continuation of the Agreements, typically for an additional one-year period. This meeting typically includes all the Independent Trustees, including the Trustees who do not serve on the Contract Review Committee. After the Contract Review Committee has made its recommendation, the full Board, including the Independent Trustees, determines whether to approve the continuation of the Agreements at its June Board meeting.

In connection with these meetings, the Trustees receive materials that the Funds’ investment advisers and sub-advisers, as applicable (collectively, the “Advisers”), believe to be reasonably necessary for the Trustees to evaluate the Agreements. These materials generally include, among other items, (i) information on the investment performance of the Funds and the performance of peer groups of funds and the Funds’ performance benchmarks, (ii) information on the Funds’ advisory fees and sub-advisory fees, if any, and other expenses, including information comparing the Funds’ advisory fees and sub-advisory fees, if any, to the fees charged to institutional accounts with similar strategies managed by the Advisers, if any, and to those of peer groups of funds, including, if applicable, the Fund’s corresponding mutual fund, and information about any applicable expense limitations and/or fee “breakpoints,” (iii) sales, redemption and trading data in respect of the Funds, (iv) information about the profitability of the Agreements to the Advisers, including how profitability is determined for the Funds, and (v) information obtained through the completion by the Advisers of a questionnaire distributed on behalf of the Trustees. The Board, including the Independent Trustees, also considers other matters such as (i) each Fund’s investment objective and strategies and the size, education and experience of the Advisers’ respective investment staffs and their use of technology, external research and trading cost measurement tools, (ii) arrangements in respect of the distribution and trading of the Funds’ shares and the related costs, (iii) the allocation of the Funds’ brokerage, if any, including, if applicable, allocations to brokers affiliated with the Advisers and the use of “soft” commission dollars to pay for research and other similar services, (iv) each Adviser’s policies and procedures relating to, among other things, compliance, trading and best execution, proxy voting, liquidity and valuation, (v) information about amounts invested by the Funds’ portfolio managers in the Funds or in similar accounts that they manage and (vi) the general economic outlook with particular emphasis on the asset management industry. Throughout the process, the Trustees are afforded the opportunity to ask questions of and request additional materials from the Advisers and the Independent Trustees meet separately with independent legal counsel outside the presence of Adviser personnel.

In addition to the materials requested by the Trustees in connection with their annual consideration of the continuation of the Agreements, the Trustees receive materials in advance of each regular quarterly meeting of the Board that provide detailed information about the Funds’ investment performance and the fees charged to the Funds for advisory and other services. The information received by the Trustees generally includes, among other things, an internal performance rating for each Fund based on agreed-upon criteria, total return information for various periods, and performance rankings provided by a third-party data provider for various periods comparing a Fund against similarly categorized funds. The portfolio management team for each Fund or other representatives of the Advisers make periodic presentations to the Contract Review Committee and/or the full Board, and if a Fund is identified as presenting possible performance concerns it may be subject to more frequent Board or Committee presentations and reviews. In addition, the Trustees are periodically provided with detailed statistical information about each Fund’s portfolio. The Trustees also receive periodic updates between meetings, both at the Board and at the Committee level.

The Board most recently approved the continuation of the Agreements for a one-year period at its meeting held in June 2023. In considering whether to approve the continuation of the Agreements, the Board, including the Independent Trustees, did not identify any single factor as determinative. Individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. Matters considered by the Trustees, including the Independent Trustees, in connection with their approval of the Agreements included, but were not limited to, the factors listed below.

The nature, extent and quality of the services provided to the Funds under the Agreements. The Trustees considered the nature, extent and quality of the services provided by the Advisers and their affiliates to the Funds, which include advisory and non-advisory services directed to the needs and operations of each of the Funds as an ETF. The Trustees also considered the resources dedicated to the Funds by the Advisers and their affiliates. The Trustees noted that although the Funds are relatively new, the Advisers had extensive experience managing other types of funds and had made significant investments in the resources necessary for the management of ETFs, such as resources dedicated to the Funds’ creation and redemption processes. The Trustees also considered their experience with other funds advised or sub-advised by the Advisers, as well as the affiliation between the Advisers and Natixis Investment Managers, LLC, whose affiliates provide investment advisory services to other funds in the Natixis family of funds. The Trustees considered that certain of the Funds use a semi-transparent structure, and the Trustees considered the unique services required to operate such a structure, including the additional systems, processes and portfolio management oversight structures needed to ensure proper creation and disclosure of the proxy portfolio for such Funds.

The Trustees considered not only the advisory and sub-advisory services provided by the Advisers to the Funds, but also the benefits to the Funds from the monitoring and oversight services provided by Natixis Advisors, LLC (“Natixis Advisors”). They also

11  |

considered the administrative and shareholder services provided by Natixis Advisors and its affiliates to the Funds. They also took into consideration increases in the services provided resulting from new regulatory requirements, such as recent rules relating to the fair valuation of investments and the use of derivatives, as well as from monitoring proposed rules, such as those relating to privacy and cybersecurity, environmental, social and governance-specific disclosures, and vendor oversight.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the nature, extent and quality of services provided supported the renewal of the Agreements.

Investment performance of the Funds and the Advisers. As noted above, the Trustees received information about the performance of the Funds over various time periods, including information that compared the performance of the Funds to the performance of peer groups and categories of funds and the Funds’ respective performance benchmarks. The Board noted that while it found the data provided by the independent third-party data provider useful, it recognized its limitations, including, in particular, that notable differences may exist between the Funds and the performance comparisons (for example, with respect to investment strategies) and that the results of the performance comparisons may vary depending on (i) the end dates for the performance periods that were selected and (ii) the selection of the performance comparisons. The Trustees also received information about how comparative peer groups are constructed. In addition, the Trustees reviewed data prepared by an independent third-party rating organization that analyzed the performance of the Funds using a variety of performance metrics, including metrics that measured the performance of the Funds on a risk adjusted basis.

The Board noted that, through December 31, 2022, each Fund’s one- and three-year net asset value performance, as applicable, stated as percentile rankings within categories selected by the independent third-party data provider, was as follows (where the best performance would be in the first percentile of its category):

In the case of each Fund that had performance that lagged that of a relevant category median as determined by the independent third-party data provider for certain (though not necessarily all) periods, the Board concluded that other factors relevant to performance supported renewal of the Agreements. These factors included the following: (1) that the underperformance was attributable, to a significant extent, to investment decisions (such as security selection or sector allocation) by the Adviser that were reasonable and consistent with the Fund’s investment objective and policies; (2) that the longer-term performance (i.e., for the ten-year period) for the corresponding mutual fund version of one Fund was strong, suggesting that the Fund’s investment process could result in strong long-term performance; (3) that the historic performance (i.e., for the one-, three-, five- and ten-year periods) for the corresponding mutual fund version of another Fund was strong, suggesting that the Fund’s investment process could result in strong long-term performance; (4) that the Fund is relatively new and therefore has a limited performance history and (5) that the Fund had outperformed its relevant benchmark for the one-year period ended December 31, 2022. The Board also considered information about the Funds’ more recent performance, including how performance over various periods had been impacted by various factors such as market and economic events.

The Trustees also considered each Adviser’s performance and reputation generally, the performance of the fund family generally, and the historical responsiveness of the Advisers to Trustee concerns about performance and the willingness of the Advisers to take steps intended to improve performance.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the performance of the Funds and the Advisers and/or other relevant factors supported the renewal of the Agreements.

The costs of the services provided and the profits realized by the Advisers and their affiliates from their respective relationships with the Funds. The Trustees considered the fees charged to the Funds for advisory, sub-advisory and administrative services, as applicable, as well as the total expense levels of the Funds. This information included comparisons (provided by an independent third party) of the Funds’ advisory fees and total expense levels to those of its category groups. In evaluating each Fund’s advisory and sub-advisory fees, as applicable, the Trustees also took into account the demands, complexity and quality of the investment management of the Funds, including the additional responsibilities of the Advisers in overseeing an ETF, and the need for the Advisers to offer competitive compensation and the potential need to expend additional resources to the extent the Funds grow in size. The Trustees also considered that over the past several years, management had demonstrated its intention to have competitive fee levels by making recommendations regarding reductions in advisory fee rates, implementation of advisory fee breakpoints and the institution of advisory fee waivers and expense limitations for various funds in the fund family. They noted that the Funds have expense limitations in place

|  12

and they considered the amounts waived or reimbursed by the Advisers for the Funds under their expense limitation agreements. The Trustees further noted that management had proposed to reduce the expense limitation of Natixis Loomis Sayles Short Duration Income ETF, effective as of July 1, 2023. The Trustees also noted that Natixis Loomis Sayles Short Duration Income ETF had a total advisory fee rate that was equal to the median of its peer group of funds. The Board also considered that the fee and expense information reflected information as of a certain date and that historical asset levels may differ from current asset levels, particularly in a period of market volatility.

The Trustees noted that each of Natixis U.S. Equity Opportunities ETF, Natixis Vaughan Nelson Mid Cap ETF and Natixis Vaughan Nelson Select ETF (each a “Semi-Transparent ETF” and together, the “Semi-Transparent ETFs”) had a total advisory fee rate that was above the median of a peer group of funds. In this regard, the Trustees considered factors that management believed justified the relatively higher advisory fee rates, including (1) that peer grouping for the Semi-Transparent ETFs was challenging given the lack of competitive products offered under the new semi-transparent structure, and management believes it is more appropriate to use the peer groupings for the corresponding mutual fund versions of the Semi-Transparent ETFs’ strategies; (2) that the advisory fee rate of Natixis U.S. Equity Opportunities ETF had been reduced last year effective July 1, 2022 and the comparison against the peer group did not reflect the full impact of that reduction; (3) that the advisory fee rate for the corresponding mutual fund version of the Natixis Vaughan Nelson Mid Cap ETF, which is the same as the advisory fee rate for the Natixis Vaughan Nelson Mid Cap ETF, was equal to its peer group, which management believes is competitive; (4) that the advisory fee rate for the corresponding mutual fund version of the Natixis Vaughan Nelson Select ETF, which is the same as the advisory fee rate for the Natixis Vaughan Nelson Select ETF, was 4 basis points higher than its peer group, which management believes is competitive; and (5) that management had developed additional systems, processes and portfolio management oversight structures to ensure proper issuance and disclosure of the proxy portfolio for each of the Semi-Transparent ETFs.

The Trustees also considered the compensation directly or indirectly received by the Advisers and their affiliates from their relationships with the Funds. The Trustees reviewed information provided by management as to the profitability of the Advisers’ and their affiliates’ relationships with the Funds, and information about how expenses are determined and allocated for purposes of profitability calculations. They also reviewed information provided by management about the effect of distribution costs and changes in asset levels on Adviser profitability, including information regarding resources spent on distribution activities. When reviewing profitability, the Trustees also considered information about court cases in which adviser compensation or profitability were issues, the performance of the Funds, the expense levels of the Funds, whether the Advisers had implemented breakpoints and/or expense limitations with respect to the Funds and the overall profit margin of Natixis Investment Managers, LLC compared to that of certain other investment managers for which such data was available. The Board also noted the competitive nature of the global asset management industry.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the advisory and sub-advisory fees charged to each of the Funds were fair and reasonable, and that the costs of these services generally and the related profitability of the Advisers and their affiliates in respect of their relationships with the Funds supported the renewal of the Agreements.

Economies of Scale. The Trustees considered the existence of any economies of scale in the provision of services by the Advisers and whether those economies are shared with the Funds through breakpoints in their investment advisory fees or other means, such as expense limitations. The Trustees also considered management’s explanation of the factors that are taken into account with respect to the implementation of breakpoints in investment advisory fees or expense limitations, which reduced the total expenses borne by shareholders. With respect to economies of scale, the Trustees noted that Natixis Vaughan Nelson Mid Cap ETF has breakpoints in its advisory fee and that each of the Funds was subject to an expense limitation. The Trustees also considered management’s proposal to reduce the expense limitation for Natixis Loomis Sayles Short Duration Income ETF. In considering these issues, the Trustees also took note of the costs of the services provided (both on an absolute and on a relative basis) and the profitability to the Advisers and their affiliates of their relationships with the Funds, as discussed above. The Trustees also considered that the Funds have benefitted from the substantial reinvestment each Adviser has made into its business. They also considered that because of their relatively small size, the Funds did not have significant economies of scale.

After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding each of the Agreements, that the extent to which economies of scale were shared with the Funds supported the renewal of the Agreements.

The Trustees also considered other factors, which included but were not limited to the following:

13  |

Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent counsel, the Trustees, including the Independent Trustees, concluded that each of the existing Agreements should be continued through June 30, 2024.

Effective December 1, 2018 (September 16, 2020 for Natixis U.S. Equity Opportunities ETF, Natixis Vaughan Nelson Mid Cap ETF and Natixis Vaughan Nelson Select ETF, and June 28, 2023 for Natixis Loomis Sayles Focused Growth ETF), the Funds adopted a liquidity risk management program (the “Program”) pursuant to the requirements of Rule 22e-4 under the Investment Company Act of 1940, as amended (the “Rule”). The Rule requires registered open-end funds, including mutual funds and exchange-traded funds to establish liquidity risk management programs in order to effectively manage fund liquidity and mitigate the risk that a fund could not meet redemption requests without significantly diluting the interests of remaining investors.

The Rule requires the Funds to assess, manage and review their liquidity risk considering applicable factors during normal and foreseeable stressed conditions. In fulfilling this requirement, each Fund assesses and reviews (where applicable and amongst other matters) its investment strategy, portfolio holdings, possible investment concentrations, use of derivatives, short-term and long-term cash flow projections, use of cash and cash equivalents, as well as borrowing arrangements and other funding sources. Each Program has established a Program Administrator (“Administrator”) which is the adviser or sub-adviser of the Fund.

In accordance with the Program, each of the Fund’s portfolio investments is classified into one of four liquidity categories based on a determination of a reasonable expectation for how long it would take to convert the investment to cash (or sell or dispose of the investment) without significantly changing its market value.

Each Fund is prohibited from acquiring an investment if, after the acquisition, its holdings of illiquid assets will exceed 15% of its net assets. If a Fund does not hold a majority of highly liquid investments in its portfolio, then the Fund is required to establish a highly liquid investment minimum (“HLIM”). None of the Funds has established an HLIM.

During the period from January 1, 2022 to December 31, 2022, there were no material changes to the Programs and no material events that impacted the operation of the Funds’ Programs. During the period, the Funds held sufficient liquid assets to meet redemptions on a timely basis and did not have any illiquid security violations.

During the period January 1, 2023 through June 30, 2023, the Funds held sufficient liquid assets to meet redemptions on a timely basis and did not have any illiquid security violations.    

Annual Program Assessment and Conclusion

In the opinion of the Program Administrators, the Program of each Fund approved by the Funds’ Board is operating effectively. The Program Administrators have also monitored, assessed and managed each Fund’s liquidity risk regularly throughout the period.

Pursuant to the Rule’s requirements, the Board has received and reviewed a written report prepared by each Fund’s Program Administrator that addressed the operation of the Programs, assessed their adequacy and effectiveness and described any material changes made to the Programs.
