&lt;p style="font: bold 10pt/11pt Times New Roman, Times, Serif; margin: 3pt 0 0"&gt;Common Stock Selection.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;Our
approach to selecting stocks is based on a proprietary rules-based selection process which is consistently applied. This process embodies
key elements of our investment philosophy by focusing on financial measures that are least susceptible to accounting distortions and erroneous
corporate guidance.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;When
selecting stocks for each portfolio, we apply a model which analyzes large-cap, mid-cap, small-cap, and international stocks to assess
valuations based on multiple risk, value, and growth factors. Our goal is to identify stocks which exhibit the fundamental characteristics
that enable them to provide the greatest potential for capital appreciation.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;&lt;span style="letter-spacing: -0.05pt"&gt;The
first step in our selection process is to establish a universe of stocks from which the portfolios will be selected. The universe is identified
as of five business days prior to the Initial Date of Deposit and divided into seven distinct styles consisting of six domestic equity
asset classes noted above and one international equity asset class.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;The domestic universe is established by
identifying the 3,000 largest U.S. stocks (excluding limited partnerships, royalty trusts, regulated investment companies and business
development companies) and then separating them into large-cap (largest 10%), mid-cap (next 20%) and small-cap (remaining 70%). The stocks
in each group are then divided evenly between growth and value by their price to book ratios to establish the universe of stocks eligible
for selection from within each market capitalization range. In the case of the small-cap universe, only the 250 largest stocks with a
minimum average daily trading volume of $1,000,000 within each growth and value group are included to ensure sufficient liquidity. The
international universe consists of the 100 largest companies from developed nations whose shares are either directly listed on a U.S.
securities exchange or are in the form of American Depositary Receipts/ADRs which trade on the over-the-counter market or are listed on
a U.S. securities exchange. Regardless of universe, stocks with a price of $1,000 or higher per share are not eligible for selection.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;We then rank the stocks within each of
the seven universes based on two multi-factor models, with each factor within a model receiving an equal weight. Half of a stock&#x2019;s
ranking is based on a risk model and applies to all seven universes. The remaining half of a stock&#x2019;s ranking is based on a model
which is determined by the stock&#x2019;s style designation (i.e., growth, value or international). Value and international stocks are
ranked together on one model, while growth stocks are ranked using a separate model.&lt;/p&gt;

&lt;p style="font: bold 10pt/11pt Times New Roman, Times, Serif; margin: 3pt 0 0"&gt;Stock Selection Factors.&lt;/p&gt;

&lt;p style="font: 10pt/10pt Times New Roman, Times, Serif; margin: 0 0 0 0.25in"&gt;Risk Model. The following factors are used to evaluate
and rank the stocks within the model:&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Debt to equity ratio&lt;/i&gt;. Compares a company&#x2019;s long-term debt to its stockholder&#x2019;s equity. Companies that have a lower debt to equity ratio are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Beta&lt;/i&gt;. Compares a security&#x2019;s volatility relative to the market. A security with a beta less than 1.0 would generally be considered lower risk than the market. Companies that have a lower beta are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Earnings variability&lt;/i&gt;. Compares a company&#x2019;s trailing 12-months earnings per share from the previous five years against a linear trend line. Companies that have more consistent earnings growth are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt/10pt Times New Roman, Times, Serif; margin: 0 0 0 0.25in"&gt;Value &amp;amp; International Model. The following factors
are used to evaluate and rank the stocks within the model:&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Price to book ratio&lt;/i&gt;. Compares a company&#x2019;s market capitalization to its book value. Companies that have a lower, but positive, price to book ratio are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Price to cash flow ratio&lt;/i&gt;. Compares a company&#x2019;s market capitalization to its cash flow generated. Companies that have a lower, but positive, price to cash flow ratio are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Return on assets&lt;/i&gt;. Compares a company&#x2019;s trailing 12-months net income to its total assets. Companies that have higher return on assets are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;

    &lt;td&gt;&lt;i&gt;3-month price appreciation&lt;/i&gt;. Companies are numerically ranked by their stock&#x2019;s trailing three-month price appreciation, with a preference to those with the greatest price appreciation.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 0 0.25in"&gt;Growth Model. The following factors are used to evaluate
and rank the stocks within the model:&lt;/p&gt;

&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Price to sales ratio&lt;/i&gt;. Compares a company&#x2019;s market capitalization to revenue generated. Companies that have a lower price to sales ratio are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Price to cash flow ratio&lt;/i&gt;. Compares a company&#x2019;s market capitalization to its cash flow generated. Companies that have a lower, but positive, price to cash flow ratio are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;Change in return on assets&lt;/i&gt;. Compares a company&#x2019;s current return on assets relative to a year ago. Companies that have a higher change in return on assets are assigned a higher ranking.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;table cellpadding="0" cellspacing="0" style="font: 10pt/11pt Times New Roman, Times, Serif; margin-top: 0; margin-bottom: 0; width: 100%"&gt;
  &lt;tr style="vertical-align: top"&gt;
    &lt;td style="width: 0.25in"&gt;&#160;&lt;/td&gt;
    &lt;td style="width: 0.25in"&gt;&#x2022;&lt;/td&gt;
    &lt;td&gt;&lt;i&gt;6-month price appreciation&lt;/i&gt;. Companies are numerically ranked by their stock&#x2019;s trailing six-month price appreciation, with a preference to those with the greatest price appreciation.&lt;/td&gt;&lt;/tr&gt;
  &lt;/table&gt;
&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;The 30 stocks with the best overall ranking
from each of the seven style classes are selected for the portfolio, subject to a maximum of six stocks from any one of the major market
sectors as determined by S&amp;amp;P&#x2019;s Global Industry Classification Standard (&#x201c;GICS&lt;sup&gt;&#xae;&lt;/sup&gt;&#x201d;). The Financials
and Real Estate sectors are combined for the sector limit purpose. If more than six stocks from any one of the major GICS&lt;sup&gt;&#xae;&lt;/sup&gt;
sectors are selected, those stocks are excluded and replaced with the next best scoring stocks which satisfy the criteria set forth above.
In the event of a tie, the stock with the better price to cash flow ratio is selected.&lt;/p&gt;

&lt;p style="font: bold 10pt/11pt Times New Roman, Times, Serif; margin: 3pt 0 0"&gt;Fixed Income ETF Selection.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;For the fixed income portion of each portfolio
we include ETFs which invest in a variety of fixed income securities, which may include investment grade and high-yield corporate bonds,
mortgage-backed securities, senior loans, covenant-lite loans, treasury bonds and agency bonds. The Sponsor does not require specific
duration, maturity or investment quality policies when selecting the ETFs for each portfolio.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;We perform rigorous analysis and employ
a disciplined portfolio construction process when selecting ETFs to include in the portfolio. Primarily, we prefer larger funds with higher
trading volumes and we look for funds with higher yields, as well as those that have shown a relatively consistent distribution over time.
We also consider a fund&#x2019;s ability to continue its distribution payments in the future.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;The next step in our process is to consider
current economic events that might affect financial markets generally and/or the ETF market, as well as news relating to a specific ETF,
ETF group or category of funds. In evaluating the fixed income ETFs, we also review the credit quality of the underlying securities held
by the funds. If funds are substantially similar with regard to their fixed income characteristics, funds with lower expense ratios will
be selected.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;We consult with our fixed income research
teams and portfolio management teams who understand the unique factors that drive risk adjusted returns within various asset classes to
develop the overall strategic allocation of the fixed income portfolio. Based on these factors, we create a broadly diversified fixed
income portfolio with an emphasis on higher income funds.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;In connection with the Trusts&#x2019; investments
in ETFs advised by First Trust Advisors L.P., an affiliate of the Trusts&#x2019; Sponsor, First Trust Advisors L.P. will receive advisory
fees from the underlying ETFs which it would not otherwise receive if the Trusts invested solely in ETFs advised by unaffiliated third-parties.
This may provide an incentive for the Sponsor to select ETFs advised by First Trust Advisors L.P. over ETFs advised by unaffiliated third-parties.
The Sponsor may invest in an affiliated ETF even in circumstances where an unaffiliated ETF may have lower fees or better performance
over certain time periods. However, the Sponsor selected what it considered to be the best suited ETFs to achieve the Trusts&#x2019; investment
objectives even though there may be other ETFs, including those advised by unaffiliated third-parties, that provide similar results.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;Please note that we applied the strategies
which make up a portion of the portfolio for a Trust at a particular time. If we create additional Units of a Trust after the Initial
Date of Deposit we will deposit the Securities originally selected by applying the strategy on the Initial Date of Deposit. This is true
even if a later application of the strategy would have resulted in the selection of different securities. The Securities were selected
as of the strategy&#x2019;s selection date using closing market prices on such date or, if a particular market was not open for trading
on such date, closing market prices on the day immediately prior to the strategy&#x2019;s selection date in which such market was open.
In addition, companies which, based on publicly available information as of the date the Securities were selected, are the subject of
an announced business combination which we expect will happen within 12 months of the date of this prospectus, or companies which are
subject to any of the limited circumstances which warrant removal of a Security from a Trust as described under &#x201c;Removing Securities
from a Trust,&#x201d; are not eligible for inclusion in a Trust&#x2019;s portfolio.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;While not a part of each Trust&#x2019;s
portfolio selection process, each Trust also has exposure to dividend-paying securities through each Trust&#x2019;s investments in the
Common Stocks, and to depositary receipts through each Trust&#x2019;s investments in the Funds. Each Trust&#x2019;s portfolio may include
both actively managed ETFs and ETFs that track an index.&lt;/p&gt;

&lt;p style="font: 10pt/11pt Times New Roman, Times, Serif; margin: 0 0 2pt; text-indent: 0.25in"&gt;As with any similar investments, there
can be no assurance that the objective of a Trust will be achieved. See &#x201c;Risk Factors&#x201d; for a discussion of the risks of investing
in a Trust.&lt;/p&gt;
