                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2022


Dear Shareholders:

First Trust is pleased to provide you with the semi-annual report for the First
Trust Enhanced Short Maturity ETF (the "Fund"), which contains detailed
information about the Fund for the six months ended April 30, 2022.

A couple of famous financial industry quotes came to mind recently as I was
sizing up the current business climate: "There's no such thing as a free lunch"
and "Don't fight the Fed!" It seems that for some, the trillions of dollars of
financial stimulus funneled into U.S. households and businesses by the Federal
government and its agencies to help mitigate the fallout stemming from the
coronavirus ("COVID-19") pandemic, which commenced sometime around February
2020, was for all intents and purposes "free money." It was not free. From the
close of February 2020 through March 2022, the Federal Reserve (the "Fed")
expanded the U.S. money supply, known as M2, by 41% to $21.81 trillion to boost
liquidity in the financial system. Normally, M2 grows around 6.0% on a
year-over-year basis. When you factor in that all this new capital was
accompanied by a breakdown of the global supply chain, there is little wonder
why inflation is rampant.

One of the more common definitions of inflation is too many dollars chasing too
few goods. The biggest downside to the supply chain bottlenecks, such as the
severe backup of container ships at some U.S. ports, is that they have markedly
reduced the flow of imported goods to retailers. The Fed has been signaling to
Americans and the rest of the globe that, after many years of artificially low
interest rates, tighter monetary policy will likely rule the day for the
foreseeable future. Higher interest rates make borrowing capital more expensive
and that should slow consumption over time, which, in turn, should bring down
inflation. Don't fight the Fed is code for don't bet against the Fed, in my
opinion. Stay tuned!

The primary job of the Fed is price stability. Its standard inflation target
rate is 2.0%. The most recent Consumer Price Index release showed that prices
were up 8.3% on a year-over-year basis as of April 30, 2022, according to data
from the U.S. Bureau of Labor Statistics. While down from 8.5% the prior month,
it is clearly elevated and that means the Fed has some work to do to with
respect to mitigating inflation. The war between Russia and Ukraine is making
the Fed's job even tougher, particularly in the areas of food and energy. Rising
costs and potential shortages could become even bigger if the COVID-19 outbreak
in China grows. These are important events to monitor. Fed Chairman Jerome
Powell has stated that the Fed is poised to raise the Federal Funds target rate
(upper bound) by 50 basis points at each of its next two meetings (set for June
and July), which would take the rate up to 2.00%. Data from CME Group indicates
that current market pricing has the rate rising to 2.75% or 3.00% by year-end.

Securities markets do not go up in a straight line and they do not just go up
year in and year out. In fact, what we have witnessed over the past couple of
decades are often referred to as boom and bust cycles. Thankfully, it has ended
up more boom than bust. Simply put, investors, not traders of the market, need
to be willing to take the bad with the good. As the various stages of an
economic cycle come and go (expansion to contraction), the markets tend to
reprice securities to reflect the current narrative. In other words, we believe
the markets essentially heal themselves - if you let them. That is an accurate
depiction of how the markets have behaved so far in 2022, in my opinion. In
response to a softening economy, the stock and bond markets have experienced
some serious downside through the first four months of this year, as measured by
the broader market indices. As of today, Brian Wesbury, Chief Economist at First
Trust, is not forecasting a recession for the U.S. in 2022 or 2023. Whether he
is proven right or wrong, we encourage investors to stay the course.

Thank you for giving First Trust the opportunity to play a role in your
financial future. We value our relationship with you and will report on the Fund
again in six months.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

The First Trust Enhanced Short Maturity ETF's (the "Fund") investment objective
is to seek current income, consistent with preservation of capital and daily
liquidity. Under normal market conditions, the Fund intends to achieve its
investment objective by investing at least 80% of its net assets in a portfolio
of U.S. dollar-denominated fixed- and variable-rate debt securities, including
securities issued or guaranteed by the U.S. government or its agencies,
instrumentalities or U.S. government-sponsored entities, residential and
commercial mortgage-backed securities, asset-backed securities, U.S. corporate
bonds, fixed income securities issued by non-U.S. corporations and governments,
municipal obligations, privately issued securities and other debt securities
bearing fixed or floating interest rates. The Fund may also invest in money
market securities. Shares of the Fund are listed on The Nasdaq Stock Market LLC
under the ticker symbol "FTSM."

The Fund's investment advisor, First Trust Advisors L.P. (the "Advisor"),
selects securities for the portfolio by evaluating fixed income sectors and
macro market trends while completing bottom-up analysis of individual
securities. Portfolio securities are selected based upon relative value in the
context of overall portfolio duration. Key inputs for the screens in the
securities selection process include, but are not limited to, credit quality,
yield, interest rate sensitivity and liquidity. The Fund's holdings are
systematically monitored for meaningful changes in performance and risk
measures. A security will generally be sold when the Advisor believes that a
security can be substituted for a similar investment that represents better
relative value; it lacks adequate compensation for embedded credit risk; or when
rebalancing the portfolio to maintain diversification. Under normal market
conditions, the Fund's average duration is expected to be less than one year and
the average maturity of the Fund's portfolio is expected to be less than three
years.

Total returns for the period since inception are calculated from the inception
date of the Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the period indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the period
indicated. The total returns would have been lower if certain fees had not been
waived and expenses reimbursed by the Advisor.

The Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint of the national best bid and offer price ("NBBO") as of
the time that the Fund's NAV is calculated. Under SEC rules, the NBBO consists
of the highest displayed buy and lowest sell prices among the various exchanges
trading the Fund at the time the Fund's NAV is calculated. Prior to January 1,
2019, the price used was the midpoint between the highest bid and the lowest
offer on the stock exchange on which shares of the Fund were listed for trading
as of the time that the Fund's NAV was calculated. Since shares of the Fund did
not trade in the secondary market until after the Fund's inception, for the
period from inception to the first day of secondary market trading in shares of
the Fund, the NAV of the Fund is used as a proxy for the secondary market
trading price to calculate market returns. NAV and market returns assume that
all distributions have been reinvested in the Fund at NAV and Market Price,
respectively.

An index is a statistical composite that tracks a specified financial market or
sector. Unlike the Fund, the index does not actually hold a portfolio of
securities and therefore does not incur the expenses incurred by the Fund. These
expenses negatively impact the performance of the Fund. Also, market returns do
not include brokerage commissions that may be payable on secondary market
transactions. If brokerage commissions were included, market returns would be
lower. The total returns presented reflect the reinvestment of dividends on
securities in the indices. The returns presented do not reflect the deduction of
taxes that a shareholder would pay on Fund distributions or the redemption or
sale of Fund shares. The investment return and principal value of shares of the
Fund will vary with changes in market conditions. Shares of the Fund may be
worth more or less than their original cost when they are redeemed or sold in
the market. The Fund's past performance is no guarantee of future performance.

(1)   The ratings are by S&P Global Ratings. A credit rating is an assessment
      provided by a nationally recognized statistical rating organization
      (NRSRO) of the creditworthiness of an issuer with respect to debt
      obligations. Ratings are measured highest to lowest on a scale that
      generally ranges from AAA to D for long-term ratings and A-1+ to C for
      short-term ratings. Investment grade is defined as those issuers that have
      a long-term credit rating of BBB- or higher or a short-term credit rating
      of A-3 or higher. The credit ratings shown relate to the credit worthiness
      of the issuers of the underlying securities in the Fund, and not to the
      Fund or its shares. U.S. Treasury and U.S. Agency mortgage-backed
      securities appear under "Government." Credit ratings are subject to
      change.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the index does
not actually hold a portfolio of securities and therefore does not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS

Information showing the number of days the market price of the Fund's shares was
greater (at a premium) and less (at a discount) than the Fund's net asset value
for the most recently completed year, and the most recently completed calendar
quarters since that year (or life of the Fund, if shorter) is available at

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2022 (UNAUDITED)

As a shareholder of First Trust Enhanced Short Maturity ETF (the "Fund"), you
incur two types of costs: (1) transaction costs; and (2) ongoing costs,
including management fees, distribution and/or service (12b-1) fees, if any, and
other Fund expenses. This Example is intended to help you understand your
ongoing costs of investing in the Fund and to compare these costs with the
ongoing costs of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2022.

ACTUAL EXPENSES

The first line in the following table provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. Simply divide your account value by $1,000 (for example, an $8,600
account value divided by $1,000 = 8.6), then multiply the result by the number
in the first line under the heading entitled "Expenses Paid During the Six-Month
Period" to estimate the expenses you paid on your account during this six-month
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio 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 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 in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

      2021 through April 30, 2022), multiplied by 181/365 (to reflect the
      six-month period).

(a)   Floating or variable rate security.

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended (the "1933 Act"), and may be resold in transactions
      exempt from registration, normally to qualified institutional buyers.
      Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be liquid by First Trust Advisors L.P.,
      the Fund's advisor (the "Advisor"). Although market instability can result
      in periods of increased overall market illiquidity, liquidity for each
      security is determined based on security specific factors and assumptions,
      which require subjective judgment. At April 30, 2022, securities noted as
      such amounted to $856,163,808 or 20.6% of net assets.

(c)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at April 30, 2022. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(d)   Step-up security. A security where the coupon increases or steps up at a
      predetermined date.

(e)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A under the 1933 Act,
      and may be resold in transactions exempt from registration, normally to
      qualified institutional buyers (see Note 2C - Restricted Securities in the
      Notes to Financial Statements.)

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2022 (UNAUDITED)

                                1. ORGANIZATION

First Trust Exchange-Traded Fund IV (the "Trust") is an open-end management
investment company organized as a Massachusetts business trust on September 15,
2010, and is registered with the Securities and Exchange Commission under the
Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of eleven funds that are offering shares. This
report covers the First Trust Enhanced Short Maturity ETF (the "Fund"), a
diversified series of the Trust, which trades under the ticker "FTSM" on The
Nasdaq Stock Market LLC ("Nasdaq"). The Fund represents a separate series of
shares of beneficial interest in the Trust. Unlike conventional mutual funds,
the Fund issues and redeems shares on a continuous basis, at net asset value
("NAV"), only in large blocks of shares known as "Creation Units."

The Fund is an actively managed exchange-traded fund ("ETF"). The Fund's
investment objective is to seek current income, consistent with preservation of
capital and daily liquidity. Under normal market conditions, the Fund intends to
achieve its investment objective by investing at least 80% of its net assets in
a portfolio of U.S. dollar-denominated fixed- and variable-rate debt securities,
including securities issued or guaranteed by the U.S. government or its
agencies, instrumentalities or U.S. government-sponsored entities, residential
and commercial mortgage-backed securities, asset-backed securities, U.S.
corporate bonds, fixed income securities issued by non-U.S. corporations and
governments, municipal obligations, privately issued securities and other debt
securities bearing fixed or floating interest rates. The Fund may also invest in
money market securities. The Fund may invest in investment companies, such as
ETFs, that invest primarily in debt securities. The Fund intends to limit its
investments in privately-issued, non-agency sponsored mortgage- and asset-backed
securities to 20% of its net assets. The Fund may also invest up to 20% of its
net assets in floating rate loans representing amounts borrowed by companies or
other entities from banks and other lenders. A significant portion of these
loans may be rated below investment grade or unrated. Floating rate loans held
by the Fund may be senior or subordinate obligations of the borrower and may or
may not be secured by collateral. Under normal market conditions, the Fund's
average duration is expected to be less than one year and the average maturity
of the Fund's portfolio is expected to be less than three years. There can be no
assurance that the Fund will achieve its investment objective. The Fund may not
be appropriate for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund is considered an investment company and follows accounting and
reporting guidance under Financial Accounting Standards Board Accounting
Standards Codification Topic 946, "Financial Services-Investment Companies." The
following is a summary of significant accounting policies consistently followed
by the Fund in the preparation of the financial statements. The preparation of
the financial statements in accordance with accounting principles generally
accepted in the United States of America ("U.S. GAAP") requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION

The Fund's NAV is determined daily as of the close of regular trading on the New
York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern time, on each day the
NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV
is determined as of that time. Domestic debt securities and foreign securities
are priced using data reflecting the earlier closing of the principal markets
for those securities. The Fund's NAV is calculated by dividing the value of all
assets of the Fund (including accrued interest and dividends), less all
liabilities (including accrued expenses and dividends declared but unpaid), by
the total number of shares outstanding.

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Fund's
investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Trust's Board of
Trustees, and in accordance with provisions of the 1940 Act. Investments valued
by the Advisor's Pricing Committee, if any, are footnoted as such in the
footnotes to the Portfolio of Investments. The Fund's investments are valued as
follows:

      Corporate bonds, corporate notes, U.S. government securities,
      mortgage-backed securities, asset-backed securities, certificates of
      deposit and other debt securities are fair valued on the basis of
      valuations provided by dealers who make markets in such securities or by a
      third-party pricing service approved by the Trust's Board of Trustees,
      which may use the following valuation inputs when available:

            1)    benchmark yields;
            2)    reported trades;
            3)    broker/dealer quotes;


                                                                         Page 29

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2022 (UNAUDITED)

            4)    issuer spreads;
            5)    benchmark securities;
            6)    bids and offers; and
            7)    reference data including market research publications.

      Securities traded in an over-the-counter market are fair valued at the
      mean of their most recent bid and asked price, if available, and otherwise
      at their closing bid price.

      Commercial paper is fair valued at cost adjusted for amortization of
      premiums and accretion of discounts (amortized cost), provided the
      Advisor's Pricing Committee has determined that the use of amortized cost
      is an appropriate reflection of fair value given market and
      issuer-specific conditions existing at the time of the determination.
      Factors that may be considered in determining the appropriateness of the
      use of amortized cost include, but are not limited to, the following:

            1)    the credit conditions in the relevant market and changes
                  thereto;
            2)    the liquidity conditions in the relevant market and changes
                  thereto;
            3)    the interest rate conditions in the relevant market and
                  changes thereto (such as significant changes in interest
                  rates);
            4)    issuer-specific conditions (such as significant credit
                  deterioration); and
            5)    any other market-based data the Advisor's Pricing Committee
                  considers relevant. In this regard, the Advisor's Pricing
                  Committee may use last-obtained market-based data to assist it
                  when valuing portfolio securities using amortized cost.

      Senior Floating-Rate Loan Interests ("Senior Loans")(1) are not listed on
      any securities exchange or board of trade. Senior Loans are typically
      bought and sold by institutional investors in individually negotiated
      private transactions that function in many respects like an
      over-the-counter secondary market, although typically no formal
      market-makers exist. This market, while having grown substantially since
      its inception, generally has fewer trades and less liquidity than the
      secondary market for other types of securities. Some Senior Loans have few
      or no trades, or trade infrequently, and information regarding a specific
      Senior Loan may not be widely available or may be incomplete. Accordingly,
      determinations of the market value of Senior Loans may be based on
      infrequent and dated information. Because there is less reliable,
      objective data available, elements of judgment may play a greater role in
      valuation of Senior Loans than for other types of securities. Typically,
      Senior Loans are fair valued using information provided by a third-party
      pricing service. The third-party pricing service primarily uses
      over-the-counter pricing from dealer runs and broker quotes from
      indicative sheets to value the Senior Loans.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended (the "1933 Act")) for which a third-party pricing service is
unable to provide a market price; securities whose trading has been formally
suspended; a security whose market or fair value price is not available from a
pre-established pricing source; a security with respect to which an event has
occurred that is likely to materially affect the value of the security after the
market has closed but before the calculation of the Fund's NAV or make it
difficult or impossible to obtain a reliable market quotation; and a security
whose price, as provided by the third-party pricing service, does not reflect
the security's fair value. As a general principle, the current fair value of a
security would appear to be the amount which the owner might reasonably expect
to receive for the security upon its current sale. When fair value prices are
used, generally they will differ from market quotations or official closing
prices on the applicable exchanges. A variety of factors may be considered in
determining the fair value of such securities, including, but not limited to,
the following:

            1)    the fundamental business data relating to the borrower/issuer;

            2)    an evaluation of the forces which influence the market in
                  which these securities are purchased and sold;

            3)    the type, size and cost of a security;

            4)    the financial statements of the borrower/issuer;

            5)    the credit quality and cash flow of the borrower/issuer, based
                  on the Advisor's or external analysis;

            6)    the information as to any transactions in or offers for the
                  security;

            7)    the price and extent of public trading in similar securities
                  of the borrower/issuer, or comparable companies;

            8)    the coupon payments;

            9)    the quality, value and salability of collateral, if any,
                  securing the security;

           10)    the business prospects of the borrower/issuer, including any
                  ability to obtain money or resources from a parent or
                  affiliate and an assessment of the borrower's/issuer's
                  management (for corporate debt only);

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2022 (UNAUDITED)

           11)    the prospects for the borrower's/issuer's industry, and
                  multiples (of earnings and/or cash flows) being paid for
                  similar businesses in that industry (for corporate debt only);

           12)    the borrower's/issuer's competitive position within the
                  industry;

           13)    the borrower's/issuer's ability to access additional liquidity
                  through public and/or private markets; and

           14)    other relevant factors.

The Fund is subject to fair value accounting standards that define fair value,
establish the framework for measuring fair value and provide a three-level
hierarchy for fair valuation based upon the inputs to the valuation as of the
measurement date. The three levels of the fair value hierarchy are as follows:

      o     Level 1 - Level 1 inputs are quoted prices in active markets for
            identical investments. An active market is a market in which
            transactions for the investment occur with sufficient frequency and
            volume to provide pricing information on an ongoing basis.

      o     Level 2 - Level 2 inputs are observable inputs, either directly or
            indirectly, and include the following:

            o     Quoted prices for similar investments in active markets.

            o     Quoted prices for identical or similar investments in markets
                  that are non-active. A non-active market is a market where
                  there are few transactions for the investment, the prices are
                  not current, or price quotations vary substantially either
                  over time or among market makers, or in which little
                  information is released publicly.

            o     Inputs other than quoted prices that are observable for the
                  investment (for example, interest rates and yield curves
                  observable at commonly quoted intervals, volatilities,
                  prepayment speeds, loss severities, credit risks, and default
                  rates).

            o     Inputs that are derived principally from or corroborated by
                  observable market data by correlation or other means.

      o     Level 3 - Level 3 inputs are unobservable inputs. Unobservable
            inputs may reflect the reporting entity's own assumptions about the
            assumptions that market participants would use in pricing the
            investment.

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2022, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income is recorded
daily on the accrual basis. Amortization of premiums and accretion of discounts
are recorded using the effective interest method.

The United Kingdom's Financial Conduct Authority (the "FCA"), which regulates
the London Interbank Offered Rates ("LIBOR") announced on March 5, 2021 that it
intended to phase-out all LIBOR reference rates, beginning December 31, 2021.
Since that announcement, the FCA has ceased publication of all non-USD LIBOR
reference rates and the 1-week and 2-month USD LIBOR reference rates as of
December 31, 2021. The remaining USD LIBOR settings will cease to be published
or no longer be representative immediately after June 30, 2023. The
International Swaps and Derivatives Association, Inc. ("ISDA") confirmed that
the FCA's March 5, 2021 announcement of its intention to cease providing LIBOR
reference rates, constituted an index cessation event under the Interbank
Offered Rates ("IBOR") Fallbacks Supplement and the ISDA 2020 IBOR Fallbacks
Protocol for all 35 LIBOR settings and confirmed that the spread adjustment to
be used in ISDA fallbacks was fixed as of the date of the announcement.

In the United States, the Alternative Reference Rates Committee (the "ARRC"), a
group of market participants convened by the Board of Governors of the Federal
Reserve System and the Federal Reserve Bank of New York in cooperation with
other federal and state government agencies, has since 2014 undertaken efforts
to identify U.S. dollar reference interest rates as alternatives to LIBOR and to
facilitate the mitigation of LIBOR-related risks. In June 2017, the ARRC
identified the Secured Overnight Financing Rate ("SOFR"), a broad measure of the
cost of cash overnight borrowing collateralized by U.S. Treasury securities, as
the preferred alternative for U.S. dollar LIBOR. The Federal Reserve Bank of New
York began daily publishing of SOFR in April 2018. There is no assurance that
any alternative reference rate, including SOFR, will be similar to or produce
the same value or economic equivalence as LIBOR or that instruments using an
alternative rate will have the same volume or liquidity.

At this time, it is not possible to predict the full impact of the elimination
of LIBOR and the establishment of an alternative reference rate on the Fund or
its investments.

C. RESTRICTED SECURITIES

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the 1933 Act. Prior
to registration, restricted securities may only be resold in transactions exempt
from registration under Rule 144A under the 1933 Act, normally to qualified
institutional buyers. As of April 30, 2022, the Fund held restricted securities
as shown in the following table that the Advisor has deemed illiquid pursuant to
procedures adopted by the Trust's Board of Trustees. Although market instability
can result in periods of increased overall market illiquidity, liquidity for
each security is determined based on security-specific factors and assumptions,
which require subjective judgment. The Fund does not have the right to demand
that such securities be registered. These securities are valued according to the
valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are
not expressed as a discount to the carrying value of a comparable unrestricted
security. There are no unrestricted securities with the same maturity dates and

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund, or as the Board of Trustees may determine from time to time.
Distributions of net realized gains earned by the Fund, if any, are distributed
at least annually.

Distributions in cash may be reinvested automatically in additional whole shares
only if the broker through whom the shares were purchased makes such option
available. Such shares will generally be reinvested by the broker based upon the
market price of those shares and investors may be subject to customary brokerage
commissions charged by the broker.

Distributions from net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying
treatment of income and gain/loss on portfolio securities held by the Fund and
have no impact on net assets or NAV per share. Temporary differences, which
arise from recognizing certain items of income, expense and gain/loss in
different periods for financial statement and tax purposes, will reverse at some
time in the future.

The tax character of distributions paid during the fiscal year ended October 31,
2021 was as follows:

Distributions paid from:
Ordinary income.................................   $   23,640,819
Capital gains...................................               --
Return of capital...............................               --

As of October 31, 2021, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income...................   $      388,091
Accumulated capital and other gain (loss).......      (12,700,189)
Net unrealized appreciation (depreciation)......           68,311

E. INCOME TAXES

The Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, which includes distributing substantially all of its net
investment income and net realized gains to shareholders. Accordingly, no
provision has been made for federal and state income taxes. However, due to the
timing and amount of distributions, the Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of the Fund's taxable income exceeds
the distributions from such taxable income for the calendar year.

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. The taxable years ended 2018,
2019, 2020, and 2021 remain open to federal and state audit. As of April 30,
2022, management has evaluated the application of these standards to the Fund
and has determined that no provision for income tax is required in the Fund's
financial statements for uncertain tax positions.

                           APRIL 30, 2022 (UNAUDITED)

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2021, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $12,700,189.

During the taxable year ended October 31, 2021, the Fund utilized non-expiring
capital loss carryforwards in the amount of $3,785,668.

Certain losses realized during the current fiscal year may be deferred and
treated as occurring on the first day of the following fiscal year for federal
income tax purposes. For the fiscal year ended October 31, 2021, the Fund had no
net late year ordinary or capital losses.

As of April 30, 2022, the aggregate cost, gross unrealized appreciation, gross
unrealized depreciation, and net unrealized appreciation/(depreciation) on
investments (including short positions and derivatives, if any) for federal
income tax purposes were as follows:

F. EXPENSES

Expenses, other than the investment advisory fee and other excluded expenses,
are paid by the Advisor (see Note 3).

3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the selection and ongoing monitoring of the securities
in the Fund's portfolio, managing the Fund's business affairs and providing
certain administrative services necessary for the management of the Fund.

Pursuant to the Investment Management Agreement between the Trust and Advisor,
First Trust manages the investment of the Fund's assets and is responsible for
the Fund's expenses, including the cost of transfer agency, custody, fund
administration, legal, audit and other services, but excluding fee payments
under the Investment Management Agreement, interest, taxes, acquired fund fees
and expenses with the exception of those attributable to affiliated funds,
brokerage commissions and other expenses connected with the execution of
portfolio transactions, distribution and service fees pursuant to a Rule 12b-1
plan, if any, and extraordinary expenses.

The Fund has agreed to pay First Trust an annual unitary management fee equal to
0.45% of its average daily net assets. Pursuant to two separate contractual
agreements, First Trust has agreed to waive management fees of 0.20% of average
daily net assets until March 1, 2023. The waiver agreement may be terminated by
action of the Trust's Board of Trustees at any time upon 60 days' written notice
by the Trust on behalf of the Fund or by the Fund's investment advisor only
after March 1, 2023. Pursuant to a contractual agreement between the Trust, on
behalf of the Fund, and First Trust, the management fees paid to First Trust
will be reduced by the portion of the management fees earned by First Trust from
the Fund for assets invested in other investment companies advised by First
Trust. This contractual agreement shall continue until the earlier of (i) its
termination at the direction of the Trust's Board of Trustees or (ii) upon
termination of the Fund's management agreement with First Trust; however, it is
expected to remain in place at least until March 1, 2023. First Trust does not
have the right to recover the fees waived that are attributable to the assets
invested in other investment companies advised by First Trust. During the six
months ended April 30, 2022, the Advisor waived fees of $4,140,104.

The Trust has multiple service agreements with The Bank of New York Mellon
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As
fund accountant and administrator, BNYM is responsible for maintaining the books
and records of the Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for the Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.


                                                                         Page 33

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2022 (UNAUDITED)

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund
a defined-outcome fund, or an index fund.

Additionally, the Lead Independent Trustee and the Chairs of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee Chairs
will rotate every three years. The officers and "Interested" Trustee receive no
compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The costs of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the six months ended April 30,
2022, were $0 and $56,811,533, respectively. The proceeds from sales and
paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the six months ended April 30 2022, were
$12,930,289 and $946,331,045, respectively.

For the six months ended April 30, 2022, the Fund had no in-kind transactions.

                 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

The Fund generally issues and redeems its shares in primary market transactions
through a creation and redemption mechanism and does not sell or redeem
individual shares. Instead, financial entities known as "Authorized
Participants" have contractual arrangements with the Fund's service providers to
purchase and redeem Fund shares directly with the Fund in large blocks of shares
known as "Creation Units." Prior to the start of trading on every business day,
the Fund publishes through the National Securities Clearing Corporation ("NSCC")
the "basket" of securities, cash or other assets that it will accept in exchange
for a Creation Unit of the Fund's shares. An Authorized Participant that wishes
to effectuate a creation of the Fund's shares deposits with the Fund the
"basket" of securities, cash or other assets identified by the Fund that day,
and then receives the Creation Unit of the Fund's shares in return for those
assets. After purchasing a Creation Unit, the Authorized Participant may
continue to hold the Fund's shares or sell them in the secondary market. The
redemption process is the reverse of the purchase process: the Authorized
Participant redeems a Creation Unit of the Fund's shares for a basket of
securities, cash or other assets. The combination of the creation and redemption
process with secondary market trading in the Fund's shares and underlying
securities provides arbitrage opportunities that are designed to help keep the
market price of the Fund's shares at or close to the NAV per share of the Fund.

The Fund imposes fees in connection with the purchase of Creation Units. These
fees may vary based upon various fact-based circumstances, including, but not
limited to, the composition of the securities included in the Creation Unit or
the countries in which the transactions are settled. The price for each Creation
Unit will equal the daily NAV per share of the Fund times the number of shares
in a Creation Unit, plus the fees described above and, if applicable, any
operational processing and brokerage costs, transfer fees, stamp taxes and part
or all of the spread between the expected bid and offer side of the market
related to the securities comprising the creation basket.

The Fund also imposes fees in connection with the redemption of Creation Units.
These fees may vary based upon various fact-based circumstances, including, but
not limited to, the composition of the securities included in the Creation Unit
or the countries in which the transactions are settled. The price received for
each Creation Unit will equal the daily NAV per share of the Fund times the
number of shares in a Creation Unit, minus the fees described above and, if
applicable, any operational processing and brokerage costs, transfer fees, stamp
taxes and part or all of the spread between the expected bid and offer side of
the market related to the securities comprising the redemption basket. Investors
who use the services of a broker or other such intermediary in addition to an
Authorized Participant to effect a redemption of a Creation Unit may also be
assessed an amount to cover the cost of such services. The redemption fee
charged by the Fund will comply with Rule 22c-2 of the 1940 Act which limits
redemption fees to no more than 2% of the value of the shares redeemed.

                              6. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is
authorized to pay an amount up to 0.25% of its average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Fund, for amounts expended to finance activities primarily intended to result in

the sale of Creation Units or the provision of investor services. FTP may also
use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before March 31, 2023.

                               7. INDEMNIFICATION

The Trust, on behalf of the Fund, has a variety of indemnification obligations
under contracts with its service providers. The Trust's maximum exposure under
these arrangements is unknown. However, the Trust has not had prior claims or
losses pursuant to these contracts and expects the risk of loss to be remote.

                              8. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through
the date the financial statements were issued, and has determined that there
were no subsequent events requiring recognition or disclosure in the financial
statements that have not already been disclosed.

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. CERTAIN GENERAL RISKS THAT MAY BE
APPLICABLE TO A FUND ARE IDENTIFIED BELOW, BUT NOT ALL OF THE MATERIAL RISKS
RELEVANT TO EACH FUND ARE INCLUDED IN THIS REPORT AND NOT ALL OF THE RISKS BELOW
APPLY TO EACH FUND. THE MATERIAL RISKS OF INVESTING IN EACH FUND ARE SPELLED OUT
IN ITS PROSPECTUS, STATEMENT OF ADDITIONAL INFORMATION AND OTHER REGULATORY
FILINGS. BEFORE INVESTING, YOU SHOULD CONSIDER EACH FUND'S INVESTMENT OBJECTIVE,
RISKS, CHARGES AND EXPENSES, AND READ EACH FUND'S PROSPECTUS AND STATEMENT OF
ADDITIONAL INFORMATION CAREFULLY. YOU CAN DOWNLOAD EACH FUND'S PROSPECTUS AT
WWW.FTPORTFOLIOS.COM OR CONTACT FIRST TRUST PORTFOLIOS L.P. AT (800) 621-1675 TO
REQUEST A PROSPECTUS, WHICH CONTAINS THIS AND OTHER INFORMATION ABOUT EACH FUND.

CONCENTRATION RISK. To the extent that a fund is able to invest a significant
percentage of its assets in a single asset class or the securities of issuers
within the same country, state, region, industry or sector, an adverse economic,
business or political development may affect the value of the fund's investments
more than if the fund were more broadly diversified. A fund that tracks an index
will be concentrated to the extent the fund's corresponding index is
concentrated. A concentration makes a fund more susceptible to any single
occurrence and may subject the fund to greater market risk than a fund that is
more broadly diversified.

CREDIT RISK. Credit risk is the risk that an issuer of a security will be unable
or unwilling to make dividend, interest and/or principal payments when due and
the related risk that the value of a security may decline because of concerns
about the issuer's ability to make such payments.

CYBER SECURITY RISK. The funds are susceptible to potential operational risks
through breaches in cyber security. A breach in cyber security refers to both
intentional and unintentional events that may cause a fund to lose proprietary
information, suffer data corruption or lose operational capacity. Such events
could cause a fund to incur regulatory penalties, reputational damage,
additional compliance costs associated with corrective measures and/or financial
loss. In addition, cyber security breaches of a fund's third-party service
providers, such as its administrator, transfer agent, custodian, or sub-advisor,
as applicable, or issuers in which the fund invests, can also subject a fund to
many of the same risks associated with direct cyber security breaches.

DEFINED OUTCOME FUNDS RISK. To the extent a fund's investment strategy is
designed to deliver returns tied to the price performance of an underlying ETF,
an investor may not realize the returns the fund seeks to achieve if that
investor does not hold shares for the entire target outcome period. In the event
an investor purchases shares after the first day of the target outcome period or
sells shares prior to the end of the target outcome period, the buffer that the
fund seeks to provide against a decline in the value of the underlying ETF may
not be available, the enhanced returns that the fund seeks to provide (if any)
may not be available and the investor may not participate in a gain in the value
of the underlying ETF up to the cap for the investor's investment period.
Additionally, the fund will not participate in gains of the underlying ETF above
the cap and a shareholder may lose their entire investment. If the fund seeks
enhanced returns, there are certain time periods when the value of the fund may
fall faster than the value of the underlying ETF, and it is very unlikely that,
on any given day during which the underlying ETF share price increases in value,
the fund's share price will increase at the same rate as the enhanced returns
sought by the fund, which is designed for an entire target outcome period.
Trading flexible exchange options involves risks different from, or possibly
greater than, the risks associated with investing directly in securities, such
as less liquidity and correlation and valuation risks. A fund may experience
substantial downside from specific flexible exchange option positions and
certain positions may expire worthless.

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2022 (UNAUDITED)

DERIVATIVES RISK. To the extent a fund uses derivative instruments such as
futures contracts, options contracts and swaps, the fund may experience losses
because of adverse movements in the price or value of the underlying asset,
index or rate, which may be magnified by certain features of the derivative.
These risks are heightened when a fund's portfolio managers use derivatives to
enhance the fund's return or as a substitute for a position or security, rather
than solely to hedge (or offset) the risk of a position or security held by the
fund.

EQUITY SECURITIES RISK. To the extent a fund invests in equity securities, the
value of the fund's shares will fluctuate with changes in the value of the
equity securities. Equity securities prices fluctuate for several reasons,
including changes in investors' perceptions of the financial condition of an
issuer or the general condition of the relevant stock market, such as market
volatility, or when political or economic events affecting the issuers occur. In
addition, common stock prices may be particularly sensitive to rising interest
rates, as the cost of capital rises and borrowing costs increase. Equity
securities may decline significantly in price over short or extended periods of
time, and such declines may occur in the equity market as a whole, or they may
occur in only a particular country, company, industry or sector of the market.

ETF RISK. The shares of an ETF trade like common stock and represent an interest
in a portfolio of securities. The risks of owning an ETF generally reflect the
risks of owning the underlying securities, although lack of liquidity in an ETF
could result in it being more volatile and ETFs have management fees that
increase their costs. Shares of an ETF trade on an exchange at market prices
rather than net asset value, which may cause the shares to trade at a price
greater than net asset value (premium) or less than net asset value (discount).
In times of market stress, decisions by market makers to reduce or step away
from their role of providing a market for an ETF's shares, or decisions by an
ETF's authorized participants that they are unable or unwilling to proceed with
creation and/or redemption orders of an ETF's shares, could result in shares of
the ETF trading at a discount to net asset value and in greater than normal
intraday bid-ask spreads.

FIXED INCOME SECURITIES RISK. To the extent a fund invests in fixed income
securities, the fund will be subject to credit risk, income risk, interest rate
risk, liquidity risk and prepayment risk. Income risk is the risk that income
from a fund's fixed income investments could decline during periods of falling
interest rates. Interest rate risk is the risk that the value of a fund's fixed
income securities will decline because of rising interest rates. Liquidity risk
is the risk that a security cannot be purchased or sold at the time desired, or
cannot be purchased or sold without adversely affecting the price. Prepayment
risk is the risk that the securities will be redeemed or prepaid by the issuer,
resulting in lower interest payments received by the fund. In addition to these
risks, high yield securities, or "junk" bonds, are subject to greater market
fluctuations and risk of loss than securities with higher ratings, and the
market for high yield securities is generally smaller and less liquid than that
for investment grade securities.

INDEX OR MODEL CONSTITUENT RISK. Certain funds may be a constituent of one or
more indices or ETF models. As a result, such a fund may be included in one or
more index-tracking exchange-traded funds or mutual funds. Being a component
security of such a vehicle could greatly affect the trading activity involving a
fund, the size of the fund and the market volatility of the fund. Inclusion in
an index could increase demand for the fund and removal from an index could
result in outsized selling activity in a relatively short period of time. As a
result, a fund's net asset value could be negatively impacted and the fund's
market price may be significantly below its net asset value during certain
periods. In addition, index rebalances may potentially result in increased
trading activity in a fund's shares.

INDEX PROVIDER RISK. To the extent a fund seeks to track an index, it is subject
to Index Provider Risk. There is no assurance that the Index Provider will
compile the Index accurately, or that the Index will be determined, maintained,
constructed, reconstituted, rebalanced, composed, calculated or disseminated
accurately. To correct any such error, the Index Provider may carry out an
unscheduled rebalance or other modification of the Index constituents or
weightings, which may increase the fund's costs. The Index Provider does not
provide any representation or warranty in relation to the quality, accuracy or
completeness of data in the Index, and it does not guarantee that the Index will
be calculated in accordance with its stated methodology. Losses or costs
associated with any Index Provider errors generally will be borne by the fund
and its shareholders.

INVESTMENT COMPANIES RISK. To the extent a fund invests in the securities of
other investment vehicles, the fund will incur additional fees and expenses that
would not be present in a direct investment in those investment vehicles.
Furthermore, the fund's investment performance and risks are directly related to
the investment performance and risks of the investment vehicles in which the
fund invests.

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. The United Kingdom's Financial
Conduct Authority, which regulates LIBOR has ceased making LIBOR available as a
reference rate over a phase-out period that began December 31, 2021. There is no
assurance that any alternative reference rate, including the Secured Overnight
Financing Rate ("SOFR") will be similar to or produce the same value or economic
equivalence as LIBOR or that instruments using an alternative rate will have the
same volume or liquidity. The unavailability or replacement of LIBOR may affect
the value, liquidity or return on certain fund investments and may result in


                                                                         Page 37

                           APRIL 30, 2022 (UNAUDITED)

costs incurred in connection with closing out positions and entering into new
trades. Any potential effects of the transition away from LIBOR on the fund or
on certain instruments in which the fund invests can be difficult to ascertain,
and they may vary depending on a variety of factors, and they could result in
losses to the fund.

MANAGEMENT RISK. To the extent that a fund is actively managed, it is subject to
management risk. In managing an actively-managed fund's investment portfolio,
the fund's portfolio managers will apply investment techniques and risk analyses
that may not have the desired result. There can be no guarantee that a fund will
meet its investment objective.

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. In February 2022, Russia invaded Ukraine which has caused and could
continue to cause significant market disruptions and volatility within the
markets in Russia, Europe, and the United States. The hostilities and sanctions
resulting from those hostilities could have a significant impact on certain fund
investments as well as fund performance. The outbreak of the respiratory disease
designated as COVID-19 in December 2019 has caused significant volatility and
declines in global financial markets, which have caused losses for investors.
While the development of vaccines has slowed the spread of the virus and allowed
for the resumption of "reasonably" normal business activity in the United
States, many countries continue to impose lockdown measures in an attempt to
slow the spread. Additionally, there is no guarantee that vaccines will be
effective against emerging variants of the disease.

NON-U.S. SECURITIES RISK. To the extent a fund invests in non-U.S. securities,
it is subject to additional risks not associated with securities of domestic
issuers. Non-U.S. securities are subject to higher volatility than securities of
domestic issuers due to: possible adverse political, social or economic
developments; restrictions on foreign investment or exchange of securities;
capital controls; lack of liquidity; currency exchange rates; excessive
taxation; government seizure of assets; the imposition of sanctions by foreign
governments; different legal or accounting standards; and less government
supervision and regulation of exchanges in foreign countries. Investments in
non-U.S. securities may involve higher costs than investments in U.S.
securities, including higher transaction and custody costs, as well as
additional taxes imposed by non-U.S. governments. These risks may be heightened
for securities of companies located, or with significant operations, in emerging
market countries.

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

PASSIVE INVESTMENT RISK. To the extent a fund seeks to track an index, the fund
will invest in the securities included in, or representative of, the index
regardless of their investment merit. A fund generally will not attempt to take
defensive positions in declining markets.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as
amended (the "1940 Act"), the Fund and each other fund in the First Trust Fund
Complex, other than the closed-end funds, have adopted and implemented a
liquidity risk management program (the "Program") reasonably designed to assess
and manage the funds' liquidity risk, i.e., the risk that a fund could not meet
requests to redeem shares issued by the fund without significant dilution of
remaining investors' interests in the fund. The Board of Trustees of the First
Trust Funds has appointed First Trust Advisors L.P. (the "Advisor") as the
person designated to administer the Program, and in this capacity the Advisor
performs its duties primarily through the activities and efforts of the First
Trust Liquidity Committee (the "Liquidity Committee").

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,

                           APRIL 30, 2022 (UNAUDITED)

including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the April 18, 2022 meeting of the Board of Trustees, as required by Rule
22e-4 and the Program, the Advisor provided the Board with a written report
prepared by the Advisor that addressed the operation of the Program during the
period from March 16, 2021 through the Liquidity Committee's annual meeting held
on March 17, 2022 and assessed the Program's adequacy and effectiveness of
implementation during this period, including the operation of the highly liquid
investment minimum for each fund that is required under the Program to have one,
and any material changes to the Program. Note that because the Fund primarily
holds assets that are highly liquid investments, the Fund has not adopted a
highly liquid investment minimum.

As stated in the written report, during the review period, no fund breached the
15% limitation on illiquid investments, no fund with a highly liquid investment
minimum breached that minimum and no fund filed a Form N-LIQUID. The Advisor
concluded that each fund's investment strategy is appropriate for an open-end
fund; that the Program operated effectively in all material respects during the
review period; and that the Program is reasonably designed to assess and manage
the liquidity risk of each fund and to maintain compliance with Rule 22e-4.
