                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objectives. The
Fund is subject to market risk, which is the possibility that the market values
of securities owned by the Fund will decline and that the value of the Fund's
shares may therefore be less than what you paid for them. Accordingly, you can
lose money investing in the Fund. See "Risk Considerations" in the Additional
Information section of this report for a discussion of certain other risks of
investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
www.ftportfolios.com or speak with your financial advisor. Investment returns,
net asset value and share price will fluctuate and Fund shares, when sold, may
be worth more or less than their original cost.

SHAREHOLDER LETTER
--------------------------------------------------------------------------------

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2022


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Low Duration Opportunities ETF (the "Fund"), which contains detailed information
about the Fund for the twelve months ended October 31, 2022.

As I'm writing this letter in mid-November, it strikes me that things appear to
be a little more chaotic in the current climate than normal. One of the things
that may have contributed to the chaotic nature of the news flow of late was the
November mid-term election. For the most part, except for a few seats in
Congress, the election is behind us. We learned there would be no "red wave"
(Republicans gaining a strong majority in Congress) but likely gridlock ahead.
Gridlock has been good for stock market investors in the past few decades,
particularly when there's been a Democratic president and the Republicans have
control of at least one house of Congress, according to Brian Wesbury, Chief
Economist at First Trust.

The Federal Reserve (the "Fed") has kept its promise to aggressively hike
interest rates to combat robust inflation. As of November 13, 2022, the Fed has
increased the Federal Funds target rate (upper bound) six times, from 0.25% to
4.00%. The Fed's actions have some investors and pundits looking for evidence
linking the interest rate hikes to a downturn in the economy. In short, the hope
is that a pullback in economic activity might deter the Fed from executing
further interest rate hikes. Fed Chairman Jerome Powell, however, recently said
that the terminal rate (the ultimate rate the Fed is targeting) will likely need
to be higher than previously estimated in order to curb stubbornly high
inflation. The Consumer Price Index ("CPI") is a commonly used measure of
inflation. The CPI stood at 7.7% on a trailing 12-month basis as of October 31,
2022, according to the U.S. Bureau of Labor Statistics. That is down from its
recent high of 9.1% in June 2022. Prior to this year, the last time the CPI was
higher than 7.0% was over 40 years ago. While monetary policy is an ongoing
process subject to change, the Fed does appear to be steadfast in its mission to
bring the rate of inflation back to its preferred level of 2.0%, and that will
take some time, in my opinion. Stay tuned!

Equity and fixed income markets have contended with numerous headwinds this
year, such as the war between Russia and Ukraine. Since setting its all-time
high of 4,796.56 on January 3, 2022, the S&P 500(R) Index has been in a bear
market (a price decline of 20% or more from the most recent high) for the better
part of 310 days. Suffice it to say, we are all looking forward to the end of
this bear market. With respect to corrections and bear markets, the silver
lining is that the S&P 500(R) Index has never failed to fully recover the losses
sustained in any previous downturn. Where might we see demand for stocks moving
forward? One such source could be stock buybacks. As of the last week of October
2022, U.S. companies had announced stock buybacks totaling $1 trillion so far
this year, according to Birinyi Associates. The fixed income market has not been
immune to selling pressure either. Year-to-date through November 10, 2022,
yields on the 10-Year Treasury Note increased by 258 basis points. As you may be
aware, bond yields and bond prices are inversely related, particularly with
respect to investment-grade bonds. As yields rise, prices fall and vice versa.
As noted above, the Fed has more work to do, so bond investors should not be
surprised to see interest rates and bond yields trend at least a bit higher in
the months ahead.

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.


                                                                          Page 1





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

The First Trust Low Duration Opportunities ETF's (the "Fund") primary investment
objective is to generate current income. The Fund's secondary investment
objective is to provide capital appreciation. The Fund is an actively managed
exchange-traded fund. First Trust Advisors L.P. ("First Trust" or the "Advisor")
serves as the advisor. James Snyder and Jeremiah Charles are the Fund's
portfolio managers and are jointly and primarily responsible for the day-to-day
management of the Fund's investment portfolio.

Under normal market conditions, the Fund will seek to achieve its investment
objectives by investing at least 60% of its net assets (including investment
borrowings) in mortgage-related debt securities and other mortgage-related
instruments (collectively, "Mortgage-Related Investments"). The Fund normally
expects to invest in Mortgage-Related Investments tied to residential and
commercial mortgages. Mortgage-Related Investments consist of: (1) residential
mortgage-backed securities (RMBS); (2) commercial mortgage-backed securities
(CMBS); (3) stripped mortgage-backed securities (SMBS), which are
mortgage-backed securities where mortgage payments are divided up between paying
the loan's principal and paying the loan's interest; and (4) collateralized
mortgage obligations (CMOs) and real estate mortgage investment conduits
(REMICs) where they are divided into multiple classes with each class being
entitled to a different share of the principal and/or interest payments received
from the pool of underlying assets. The Fund will limit its investment in
Mortgage-Related Investments that are neither issued nor guaranteed by the U.S.
government, or its agencies or instrumentalities to 20% of its net assets
(including investment borrowings). The Fund may invest up to 40% of its net
assets (including investment borrowings), in the aggregate, in (i) cash, cash
equivalents and short-term investments and (ii) non-mortgage direct obligations
of the U.S. government and other non-mortgage securities issued and/or
guaranteed by Government Entities. The Fund may also invest up to 5% of its net
assets (including investment borrowings) in asset-backed securities ("ABS")
(other than Mortgage-Related Investments) that are not issued and/or guaranteed
by Government Entities, or U.S. government-sponsored entities (collectively,
"Government Entities"). However, the Fund's investments in (a) Mortgage-Related
Investments that are not issued and/or guaranteed by Government Entities and (b)
ABS may not, in the aggregate, exceed 20% of the Fund's net assets (including
investment borrowings). Although the Fund intends to invest primarily in
investment grade securities, the Fund may invest up to 20% of its net assets
(including investment borrowings) in securities of any credit quality, including
securities that are below investment grade, which are also known as high yield
securities, or commonly referred to as "junk" bonds, or unrated securities that
have not been judged by the advisor to be of comparable quality to rated
investment grade securities.

------------------------------------------------------------------------------------------------------------------------------------


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 periods
indicated.

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 its 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 index. 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.

(3)   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 and Agency." 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.

Performance in securitized product investment strategies can be impacted from
the benefits of purchasing odd lot positions. The impact of these investments
can be particularly meaningful when funds have limited assets under management
and may not be a sustainable source of performance as a fund grows in size.

                                   COMMENTARY

MARKET RECAP

The 12-month period ended October 31, 2022 began with markets coming under
pressure as measures of inflation began to accelerate upward, and market
participants questioning whether inflation was truly transitory, as so
proclaimed by the Federal Reserve (the "Fed"). In a continuation of the yield
curve repricing following the September 2021 Federal Open Market Committee
meeting, bond yields once again resumed their march higher as the calendar year
flipped into 2022, as fears of the COVID-19 variant, Omicron, were pushed aside,
broader economic data remained strong, and incoming inflation data was rapidly
deteriorating. Finally, the Fed relented and abandoned its transitory language,
began to pivot and signaled very hawkish monetary policy to come. This hawkish
pivot included guidance on not only an aggressive path of future interest rate
hikes, but also signaled the use of the balance sheet to finally conclude new
purchases of U.S. Treasuries and Agency mortgage-backed securities ("MBS") and
subsequently, to let the securities mature and roll off via Quantitative
Tightening. Unfortunately for the Fed and the broader U.S. economy, inflationary
readings continued to push higher and the Fed was forced, clearly too late in
its action, in our opinion, to act very aggressively. This started in June 2022
with the first 75 basis point ("bps") hike in nearly 30 years and was followed
by successive 75 bps hikes at the Fed's July and September 2022 meetings. This
abrupt monetary policy change kicked off rather sharp moves higher in interest
rates, volatility, and risk asset pricing, with each coming under duress
throughout the 2022 calendar year. Over the course of the 12-month period ended
October 31, 2022, 2-Year Treasury yields rose 399 bps, the 5-Year Treasury yield
rose 305 bps, and the 10-Year yield rose 243 bps. These dramatic interest rate
increases caused measures of volatility to spike, with the Merrill Lynch Option
Volatility Estimate Index increasing to levels not seen since the Great
Financial Crisis of 2008-09. With upward pressure in rates and sustained
interest rate volatility, overall risk asset pricing and market liquidity have
come under significant pressure. Over the period, securitized spreads widened
with the Agency mortgage basis closing at 175 bps on October 31, 2022, which is
111 bps wider, and the Government Option-Adjusted Spread on Agency MBS widening
45 bps to close the period at 49 bps, with a period high of 64 bps.

PERFORMANCE ANALYSIS

During the 12-month period ended October 31, 2022, the Fund returned -4.96% on a
net asset value ("NAV") basis.

During the same period, the ICE BofA 1-5 Year U.S. Treasury & Agency Index (the
"Index") returned -6.52%.

During the same period, the Fund outperformed the Index by 1.56% net of fees, on
a NAV basis. Given the 2020-2021 historic ascent of home price appreciation and
correspondingly, measures of inflation, the Fund elected to strategically reduce
its overall effective duration. We remained mindful of the perceived logical
response that the Fed would be forced into to counteract such purchasing power
destruction, and as such maintained this very defensive posture on interest
rates throughout the year. Remaining mindful of the team's expectations for the
Fed's expected response function, the Fund ran a defensive spread profile and
aggressively hedged its Agency MBS exposure. Additionally, we believed that
housing would cool on both a nominal as well as real basis, as interest rates
increased and put significant pressure on affordability of housing stock. As
such, the Fund continued to migrate higher in quality, and shorter in tenor as
it related to its Non-Agency allocation. Additionally, there were periods that
the Fund built and held more cash than normal, as we felt there would be better
entry points for select opportunities. We felt that this was a prudent
reallocation of risk as the Fund reduced exposure to assets that we believed
would feel more impact from a slowing housing market and assets we felt were
more exposed to any Fed taper or additional rate increases. We believe this
reallocation provided the Fund a significant pickup in spread, helped maintain a
very short duration and allowed the Fund to more easily achieve its primary
objective. Additionally, throughout the 12-month period ended October 31, 2022,
the Fund maintained a significantly lower, and more stable overall effective


                                                                          Page 5

duration. Combined, these strategies helped to drive the relative
outperformance, which saw the Fund outperform the Index by over 150 bps on a NAV
basis during the period. Additionally, the Fund's usage of futures positions to
help manage interest rate risk and to structurally position a lower overall
effective duration was beneficial to the Fund's performance as interest rates
rose.

The Fund's monthly distribution of $0.1050 declared on October 21, 2022 and paid
on November 1, 2022 represented an annualized distribution rate of 2.69% based
on the Fund's closing market price of $46.85 as of October 31, 2022. The Fund's
distribution rate is not constant and is subject to change over time based on
the performance of the Fund and general market conditions. For the 12-month
period ended October 31, 2022, 71.73% of the distributions were characterized as
ordinary income and 28.27% were characterized as capital gain. The final
determination of the source and tax status of all 2022 distributions will be
made after the end of 2022 and will be provided on Form 1099-DIV. Not to be
construed as tax advice. Please consult your tax advisor for further information
regarding tax matters.

MARKET OUTLOOK

As expected, on the back of a massive increase in M2 money supply, limited
housing inventory, coupled with historically low interest rates, ongoing supply
chain delays and labor market shortages, inflationary pressure built to levels
not seen in 40 years. We remain mindful of both how hard it can be to tame
inflation once set in, and the impacts this can have on term premium pricing
along the U.S. yield curve. And while we believe that it won't be a straight
line, we expect yields across the curve will continue to move higher, albeit at
a much slower pace than experienced earlier this year. We believe the Fed may be
forced to hike higher than the market expects, and as such believe that the
curve inversion will continue to persist, although we do not expect
significantly deeper inversion. Inflation remains high, however we believe the
aggressive interest rate hikes implemented over the last several months have
just begun to work their way through the broader economy, and already, it
appears the housing market is beginning to cool off as month over month home
price appreciation has turned negative. Currently, we do not believe the Fed
will be an outright seller of its MBS holdings for long as measures of
volatility and illiquidity remain this elevated. We do anticipate that
heightened levels of rate volatility will remain over the shorter term, however,
to expect measures of rate volatility and spread pricing to simply return to
post-GFC/pre-COVID-19 levels in the near term and perhaps even intermediate
term, would be unrealistic, in our view. Heavy-handed Fed intervention appears
to be over; for as long as inflation persists, the Fed appears committed to the
fight. Despite the moderately bearish tone on rates, spreads are quite wide, and
we believe opportunities abound, as we are now very positive on generic Agency
MBS spread valuations, along with AAA shorter duration securitized
opportunities.

We remain committed to finding value across the various sectors of the mortgage
and securitized market, but also along the term spectrum of the U.S. yield
curve. Given the massive increase in interest rates this year, we have begun to
increase the interest rate sensitivity in the Fund as duration risks appear to
be more balanced than earlier in the year, and should yields continue to climb,
we will likely continue to extend duration. We remain committed to actively
managing the convexity component in the portfolio; meaning we do not want to
extend in duration as rates rise, and conversely, we do not want to shorten or
lose duration into a rally. From an asset allocation perspective, we plan to
take advantage of very wide spreads in select securitized opportunities that the
managers find to be attractively priced in the short to intermediate part of the
curve, which we find to be particularly attractive in light of the current curve
inversion. In our view, this approach would provide higher current income, total
return, and spread protection for shareholders. We believe this strategy can be
very effective with proper security selection, particularly when combined with
appropriate yield curve management. We plan to continue to maintain a tradeable
portfolio as that is critical to being able to act should opportunities arise.

FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2022 (UNAUDITED)

As a shareholder of First Trust Low Duration Opportunities 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 October 31, 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.

-----------------------------

(a)   Floating or variable rate security.

(b)   Inverse floating rate security.

(c)   Weighted Average Coupon security. Coupon is based on the blended interest
      rate of the underlying holdings, which may have different coupons. The
      coupon may change in any period.

(d)   Zero coupon security.

(e)   Pursuant to procedures approved by the Trust's Board of Trustees, this
      security has been determined to be illiquid by First Trust Advisors L.P.
      (the "Advisor").

(f)   Collateral Strip Rate security. Coupon is based on the weighted net
      interest rate of the investment's underlying collateral. The interest rate
      resets periodically.

(g)   This security's value was determined using significant unobservable inputs
      (see Note 2A - Portfolio Valuation in the Notes to Financial Statements).

(h)   This security is fair valued by the Advisor's Pricing Committee in
      accordance with procedures approved by the Trust's Board of Trustees, and
      in accordance with provisions of the Investment Company Act of 1940 and
      rules thereunder, as amended. At October 31, 2022, securities noted as
      such are valued at $8,750,111 or 0.2% of net assets.

(i)   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, and may be resold in transactions exempt from
      registration, normally to qualified institutional buyers. Pursuant to
      procedures approved by the Trust's Board of Trustees, this security has
      been determined to be liquid by 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 October 31, 2022,
      securities noted as such amounted to $785,287,520 or 16.1% of net assets.

(j)   All or a portion of this security is part of a mortgage dollar roll
      agreement (see Note 2I- Mortgage Dollar Rolls and TBA Transactions in the
      Notes to Financial Statements).

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

(l)   Investment in an affiliated fund.

                                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 ("SEC")
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust currently consists of twelve funds that are offering shares. This
report covers the First Trust Low Duration Opportunities ETF (the "Fund"), a
diversified series of the Trust, which trades under the ticker "LMBS" 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 primary
investment objective is to generate current income. The Fund's secondary
investment objective is to provide capital appreciation. The Fund seeks to
achieve its investment objectives by investing, under normal market conditions,
at least 60% of its net assets (including investment borrowings) in
mortgage-related debt securities and other mortgage-related instruments
(collectively, "Mortgage-Related Investments"). The Fund normally expects to
invest in Mortgage-Related Investments tied to residential and commercial
mortgages. Mortgage-Related Investments include residential mortgage-backed
securities, commercial mortgage-backed securities, stripped mortgage-backed
securities, collateralized mortgage obligations and real estate mortgage
investment conduits. The Fund may also invest in investment companies, including
ETFs, that invest primarily in Mortgage-Related Investments. The Fund will limit
its investments in Mortgage-Related Investments that are not issued or
guaranteed by Government Entities(1) to 20% of its net assets (including
investment borrowings). The Fund may invest, without limitation, in mortgage
dollar rolls. The Fund intends to enter into mortgage dollar rolls only with
high quality securities dealers and banks, as determined by the Fund's
investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor").
The Fund may also invest in to-be-announced transactions ("TBA Transactions").
Further, the Fund may enter into short sales as part of its overall portfolio
management strategies or to offset a potential decline in the value of a
security; however, the Fund does not expect, under normal market conditions, to
engage in short sales with respect to more than 30% of the value of its net
assets (including investment borrowings). Although the Fund intends to invest
primarily in investment grade securities, the Fund may invest up to 20% of its
net assets (including investment borrowings) in securities of any credit
quality, including securities that are below investment grade, which are also
known as high yield securities, or commonly referred to as "junk" bonds, or
unrated securities that have not been judged by the Advisor to be of comparable
quality to rated investment grade securities. In the case of a split rating
between one or more of the nationally recognized statistical rating
organizations, the Fund will consider the highest rating. The Fund targets an
estimated effective duration of three years or less.

                       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 readily available market quotations such as 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 Advisor's
Pricing Committee, in accordance with valuation procedures approved by the
Trust's Board of Trustees, and in accordance with provisions of the 1940 Act and
rules thereunder. 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:

      instrumentalities, and U.S. government-sponsored entities.

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2022

      U.S. government securities, mortgage-backed securities, asset-backed
      securities and other debt securities are fair valued on the basis of
      valuations provided by a third-party pricing service approved by the
      Advisor's Pricing Committee, which may use the following valuation inputs
      when available:

            1)    benchmark yields;
            2)    reported trades;
            3)    broker/dealer quotes;
            4)    issuer spreads;
            5)    benchmark securities;
            6)    bids and offers; and
            7)    reference data including market research publications.

      Pricing services generally value fixed-income securities assuming orderly
      transactions of an institutional round lot size, but a Fund may hold or
      transact in such securities in smaller, odd lot sizes. Odd lots may trade
      at lower prices than institutional round lots.

      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 last trade price.

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding Nasdaq and the London Stock Exchange
      Alternative Investment Market ("AIM")) are valued at the last sale price
      on the exchange on which they are principally traded or, for Nasdaq and
      AIM securities, the official closing price. Securities traded on more than
      one securities exchange are valued at the last sale price or official
      closing price, as applicable, at the close of the securities exchange
      representing the primary exchange for such securities.

      Shares of open-end funds are valued based on NAV per share.

      Exchange-traded futures contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded futures contracts are valued at the mean of
      their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

      Exchange-traded options contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded options contracts are valued at the mean of
      their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

      Fixed income and other debt securities having a remaining maturity of
      sixty days or less when purchased are 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.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by 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) 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

                                OCTOBER 31, 2022

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 most recent price provided by a pricing service;

            2)    the fundamental business data relating to the issuer;

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

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

            5)    the financial statements of the borrower/issuer, or financial
                  condition of the country of issue;

            6)    the credit quality and cash flow of the issuer, or country of
                  issue, based on the Pricing Committee's, sub-adviser's or
                  portfolio manager's analysis, as applicable, or external
                  analysis;

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

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

            9)    the coupon payments;

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

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

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

           13)    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 October 31, 2022, is
included with the Fund's Portfolio of Investments.

In December 2020, the SEC adopted Rule 2a-5 under the 1940 Act, establishing
requirements to determine fair value in good faith for purposes of the 1940 Act.
The rule permits fund boards to designate a fund's investment adviser to perform
fair value determinations, subject to board oversight and certain other
conditions. The rule also defines when market quotations are "readily available"
for purposes of the 1940 Act and requires a fund to fair value a portfolio
investment when a market quotation is not readily available. The SEC also
adopted new Rule 31a-4 under the 1940 Act, which sets forth recordkeeping
requirements associated with fair value determinations. The compliance date for
Rule 2a-5 and Rule 31a-4 was September 8, 2022.

Effective September 8, 2022 and pursuant to the requirements of Rule 2a-5, the
Trust's Board of Trustees designated the Advisor as its valuation designee to
perform fair value determinations and approved new Advisor Valuation Procedures
for the Trust.

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
--------------------------------------------------------------------------------

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2022

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.

The Fund invests in interest-only securities. For these securities, if there is
a change in the estimated cash flows, based on an evaluation of current
information, then the estimated yield is adjusted. Additionally, if the
evaluation of current information indicates a permanent impairment of the
security, the cost basis of the security is written down and a loss is
recognized. Debt obligations may be placed on non-accrual status and the related
interest income may be reduced by ceasing current accruals and writing off
interest receivables when the collection of all or a portion of interest has
become doubtful based on consistently applied procedures. A debt obligation is
removed from non-accrual status when the issuer resumes interest payments or
when collectability of interest is reasonably assured.

Securities purchased or sold on a when-issued, delayed-delivery or forward
purchase commitment basis may have extended settlement periods. The value of the
security so purchased is subject to market fluctuations during this period. The
Fund maintains liquid assets with a current value at least equal to the amount
of its when-issued, delayed-delivery or forward purchase commitments until
payment is made. At October 31, 2022, the Fund did not hold when-issued or
delayed-delivery securities. At October 31, 2022, the Fund held $403,398,117 of
forward purchase commitments.

C. SHORT SALES

Short sales are utilized to manage interest rate and spread risk, and are
transactions in which securities or other instruments (such as options,
forwards, futures or other derivative contracts) are sold that are not currently
owned in the Fund's portfolio. When the Fund engages in a short sale, the Fund
must borrow the security sold short and deliver the security to the
counterparty. Short selling allows the Fund to profit from a decline in a market
price to the extent such decline exceeds the transaction costs and the costs of
borrowing the securities. The Fund is charged a fee or premium to borrow the
securities sold short and is obligated to repay the lenders of the securities.
Any dividends or interest that accrues on the securities during the period of
the loan are due to the lenders. A gain, limited to the price at which the
security was sold short, or a loss, unlimited in size, will be recognized upon
the termination of the short sale; which is effected by the Fund purchasing the
security sold short and delivering the security to the lender. Any such gain or
loss may be offset, completely or in part, by the change in the value of the
long portion of the Fund's portfolio. The Fund is subject to the risk it may be
unable to reacquire a security to terminate a short position except at a price
substantially in excess of the last quoted price. Also, there is the risk that
the counterparty to a short sale may fail to honor its contractual terms,
causing a loss to the Fund.

D. FUTURES CONTRACTS

The Fund may purchase or sell (i.e., is long or short) exchange-listed futures
contracts to hedge against or gain exposure to changes in interest rates
(interest rate risk). Futures contracts are agreements between the Fund and a
counterparty to buy or sell a specific quantity of an underlying instrument at a
specified price and at a specified date. Depending on the terms of the contract,
futures contracts are settled either through physical delivery of the underlying
instrument on the settlement date or by payment of a cash settlement amount on
the settlement date. Open futures contracts can also be closed out prior to
settlement by entering into an offsetting transaction in a matching futures
contract. If the Fund is not able to enter into an offsetting transaction, the

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2022

Fund will continue to be required to maintain margin deposits on the futures
contract. When the contract is closed or expires, the Fund records a realized
gain or loss equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed or expired. This gain
or loss is included in "Net realized gain (loss) on futures contracts" on the
Statement of Operations.

Upon entering into a futures contract, the Fund must deposit funds, called
margin, with its custodian in the name of the clearing broker equal to a
specified percentage of the current value of the contract. Open futures
contracts are marked-to-market daily with the change in value recognized as a
component of "Net change in unrealized appreciation (depreciation) on futures
contracts" on the Statement of Operations. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known as
variation margin and are included in "Variation margin" receivable or payable on
the Statement of Assets and Liabilities. If market conditions change
unexpectedly, the Fund may not achieve the anticipated benefits of the futures
contract and may realize a loss. The use of futures contracts involves the risk
of imperfect correlation in movements in the price of the futures contracts,
interest rates and the underlying instruments.

E. OPTIONS CONTRACTS

The Fund may invest in exchange-listed options on U.S. Treasury securities,
exchange-listed options on U.S. Treasury futures contracts and exchange-listed
U.S. Treasury futures contracts. The Fund may also invest up to 20% of its net
assets in over-the-counter derivatives. The Fund uses derivative instruments
primarily to hedge interest rate risk and actively manage interest rate
exposure. The primary risk exposure is interest rate risk.

The Fund may purchase (buy) or write (sell) put and call options on futures
contracts and enter into closing transactions with respect to such options to
terminate an existing position. A futures option gives the holder the right, in
return for the premium paid, to assume a long position (call) or short position
(put) in a futures contract at a specified exercise price prior to the
expiration of the option. Upon exercise of a call option, the holder acquires a
long position in the futures contract and the writer is assigned the opposite
short position. In the case of a put option, the opposite is true. Prior to
exercise or expiration, a futures option contract may be closed out by an
offsetting purchase or sale of a futures option of the same series. When the
Fund writes (sells) an option, an amount equal to the premium received by the
Fund is included in "Options contracts written, at value" on the Statement of
Assets and Liabilities. When the Fund purchases (buys) an option, the premium
paid represents the cost of the option, which is included in "Premiums paid on
options contracts purchased" on the Statement of Assets and Liabilities. Options
are marked-to-market daily and their value is affected by changes in the value
of the underlying security, changes in interest rates, changes in the actual or
perceived volatility of the securities markets and the underlying securities,
and the remaining time to the option's expiration. The value of options may also
be adversely affected if the market for the options becomes less liquid or the
trading volume diminishes.

The Fund uses options on futures contracts in connection with hedging
strategies. Generally, these strategies are applied under the same market and
market sector conditions in which the Fund uses put and call options on
securities. The purchase of put options on futures contracts is analogous to the
purchase of puts on securities so as to hedge the Fund's securities holdings
against the risk of declining market prices. The writing of a call option or the
purchasing of a put option on a futures contract constitutes a partial hedge
against declining prices of securities which are deliverable upon exercise of
the futures contract. If the price at expiration of a written call option is
below the exercise price, the Fund will retain the full amount of the option
premium which provides a partial hedge against any decline that may have
occurred in the Fund's holdings of securities. If the price when the option is
exercised is above the exercise price, however, the Fund will incur a loss,
which may be offset, in whole or in part, by the increase in the value of the
securities held by the Fund that were being hedged. Writing a put option or
purchasing a call option on a futures contract serves as a partial hedge against
an increase in the value of the securities the Fund intends to acquire. Realized
gains and losses on written options are included in "Net realized gain (loss) on
written options contracts" on the Statement of Operations. Realized gains and
losses on purchased options are included in "Net realized gain (loss) on
purchased options contracts" on the Statement of Operations.

The Fund is required to deposit and maintain margin with respect to put and call
options on futures contracts written by it. Such margin deposits will vary
depending on the nature of the underlying futures contract (and the related
initial margin requirements), the current market value of the option and other
futures positions held by the Fund. The Fund will pledge in a segregated account
at the Fund's custodian, liquid assets, such as cash, U.S. government securities
or other high-grade liquid debt obligations equal in value to the amount due on
the underlying obligation. Such segregated assets will be marked-to-market
daily, and additional assets will be pledged in the segregated account whenever
the total value of the pledged assets falls below the amount due on the
underlying obligation.

The risks associated with the use of options on future contracts include the
risk that the Fund may close out its position as a writer of an option only if a
liquid secondary market exists for such options, which cannot be assured. The
Fund's successful use of options on futures contracts depends on the Advisor's
ability to correctly predict the movement in prices on futures contracts and the
underlying instruments, which may prove to be incorrect. In addition, there may
be imperfect correlation between the instruments being hedged and the futures
contract subject to option.


                                                                         Page 49

F. INTEREST-ONLY SECURITIES

An interest-only security ("IO Security") is the interest-only portion of a
mortgage-backed security that receives some or all of the interest portion of
the underlying mortgage-backed security and little or no principal. A reference
principal value called a notional value is used to calculate the amount of
interest due to the IO Security. IO Securities are sold at a deep discount to
their notional principal amount. Generally speaking, when interest rates are
falling and prepayment rates are increasing, the value of an IO Security will
fall. Conversely, when interest rates are rising and prepayment rates are
decreasing, generally the value of an IO Security will rise. These securities,
if any, are identified on the Portfolio of Investments.

G. PRINCIPAL-ONLY SECURITIES

A principal-only security ("PO Security") is the principal-only portion of a
mortgage-backed security that does not receive any interest, is priced at a deep
discount to its redemption value and ultimately receives the redemption value.
Generally speaking, when interest rates are falling and prepayment rates are
increasing, the value of a PO Security will rise. Conversely, when interest
rates are rising and prepayment rates are decreasing, generally the value of a
PO Security will fall. These securities, if any, are identified on the Portfolio
of Investments.

H. STRIPPED MORTGAGE-BACKED SECURITIES

Stripped mortgage-backed securities are created by segregating the cash flows
from underlying mortgage loans or mortgage securities to create two or more new
securities, each with a specified percentage of the underlying security's
principal or interest payments. Mortgage-backed securities may be partially
stripped so that each investor class receives some interest and some principal.
When securities are completely stripped, however, all of the interest is
distributed to holders of one type of security known as an IO Security and all
of the principal is distributed to holders of another type of security known as
a PO Security. These securities, if any, are identified on the Portfolio of
Investments.

I. MORTGAGE DOLLAR ROLLS AND TBA TRANSACTIONS

The Fund may invest, without limitation, in mortgage dollar rolls. The Fund
intends to enter into mortgage dollar rolls only with high quality securities
dealers and banks, as determined by the Fund's investment advisor. In a mortgage
dollar roll, the Fund will sell (or buy) mortgage-backed securities for delivery
on a specified date and simultaneously contract to repurchase (or sell)
substantially similar (same type, coupon and maturity) securities on a future
date. Mortgage dollar rolls are recorded as separate purchases and sales in the
Fund. The Fund may also invest in TBA Transactions. A TBA Transaction is a
method of trading mortgage-backed securities. TBA Transactions generally are
conducted in accordance with widely-accepted guidelines which establish commonly
observed terms and conditions for execution, settlement and delivery. In a TBA
Transaction, the buyer and the seller agree on general trade parameters such as
agency, settlement date, par amount and price.

J. AFFILIATED TRANSACTIONS

The Fund invests in securities of affiliated funds. Dividend income and realized
gains and losses, and change in appreciation (depreciation) from affiliated
funds are presented on the Statement of Operations. The Fund's investment
performance and risks are directly related to the investment performance and
risks of the affiliated funds.

Amounts related to these investments at October 31, 2022 and for the fiscal year
then ended are as follows:



                                                                           CHANGES IN

K. DIVIDENDS AND DISTRIBUTION 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. The Fund may also designate a portion of the amount paid to
redeeming shareholders as a distribution for tax purposes.

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.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)
--------------------------------------------------------------------------------

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2022

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 years ended October
31, 2022 and 2021 was as follows:

Distributions paid from:                              2022           2021
Ordinary income.................................  $  77,623,014  $  48,718,452
Capital gains...................................     30,590,238             --
Return of capital...............................             --     90,717,550

As of October 31, 2022, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income...................  $  (8,428,878)
Accumulated capital and other gain (loss).......             --
Net unrealized appreciation (depreciation)......   (440,777,800)

L. 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 2019,
2020, 2021, and 2022 remain open to federal and state audit. As of October 31,
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.

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, 2022, the
Fund had no non-expiring capital loss carryforwards available for federal income
tax purposes.

During the taxable year ended October 31, 2022, the Fund utilized non-expiring
capital loss carryforwards in the amount of $72,543,076.

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, 2022, the Fund had no
net late year ordinary or capital losses.

In order to present paid-in capital and accumulated distributable earnings
(loss) (which consists of accumulated net investment income (loss), accumulated
net realized gain (loss) on investments and net unrealized appreciation
(depreciation) on investments) on the Statement of Assets and Liabilities that
more closely represent their tax character, certain adjustments have been made
to paid-in capital, accumulated net investment income (loss) and accumulated net
realized gain (loss) on investments. These adjustments are primarily due to the
difference between book and tax treatments of income and gains on various
investment securities held by the Fund. The results of operations and net assets
were not affected by these adjustments. For the fiscal year ended October 31,
2022, the adjustments for the Fund were as follows:

                                Accumulated
             Accumulated        Net Realized
            Net Investment      Gain (Loss)
            Income (Loss)      on Investments     Paid-in Capital
            --------------     --------------     ---------------
            $  (24,570,905)    $   24,570,905     $            --


                                                                         Page 51

M. EXPENSES

Expenses, other than the investment advisory fee and other excluded expenses,

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 the
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, pro rata
share of fees and expenses attributable to investments in other investment
companies ("acquired fund fees and expenses"), brokerage commissions and other
expenses connected with the execution of portfolio transactions, distribution
and service fees payable 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 0.65% of its average daily net assets. In addition, the
Fund incurs acquired fund fees and expenses. The total of the unitary management
fee and acquired fund fees and expenses represents the Fund's total annual
operating expenses.

The Trust has multiple service agreements with The Bank of New York Mellon

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.

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 target 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.

The Fund does not have the right to offset financial assets and financial
liabilities related to futures and options contracts on the Statement of Assets
and Liabilities.

                 6. 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 or one of 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.


                                                                         Page 53

                                OCTOBER 31, 2022

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.

                              7. 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, 2024.

                               8. 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.

                              9. 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 was
the following subsequent event:

At a meeting on October 24, 2022, the Board of Trustees approved a breakpoint
pricing arrangement for each of the series of the Trust, including the Fund.
Pursuant to this arrangement, which is effective as of November 1, 2022, the
management fee the Fund pays to First Trust, as investment manager, will be
discounted as the Fund's net assets reach certain predefined levels.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

TO THE SHAREHOLDERS AND THE BOARD OF TRUSTEES OF FIRST TRUST EXCHANGE-TRADED
FUND IV:

OPINION ON THE FINANCIAL STATEMENTS AND FINANCIAL HIGHLIGHTS

We have audited the accompanying statement of assets and liabilities of First
Trust Low Duration Opportunities ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2022, the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, the financial highlights for each of the five years in the period then
ended, and the related notes. In our opinion, the financial statements and
financial highlights present fairly, in all material respects, the financial
position of the Fund as of October 31, 2022, and the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended in conformity with accounting principles
generally accepted in the United States of America.

BASIS FOR OPINION

These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on the Fund's
financial statements and financial highlights based on our audits. We are a
public accounting firm registered with the Public Company Accounting Oversight
Board (United States) (PCAOB) and are required to be independent with respect to
the Fund in accordance with the U.S. federal securities laws and the applicable
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements and financial highlights are
free of material misstatement, whether due to error or fraud. The Fund is not
required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting. As part of our audits, we are required to
obtain an understanding of internal control over financial reporting but not for
the purpose of expressing an opinion on the effectiveness of the Fund's internal
control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements and financial highlights, whether due
to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements and financial highlights. Our audits
also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of October 31, 2022, by correspondence with
the custodian and brokers; when replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                          OCTOBER 31, 2022 (UNAUDITED)

                      PROXY VOTING POLICIES AND PROCEDURES

A description of the policies and procedures that the Trust uses to determine

                            FEDERAL TAX INFORMATION

Distributions paid to foreign shareholders during the Fund's fiscal year ended
October 31, 2022 that were properly designated by the Fund as "interest-related

income tax provided that the income was earned directly by such foreign
shareholders.

For the year ended October 31, 2022, the amount of long-term capital gain
distributions designated by the Fund was $30,590,238 which is taxable at the
applicable capital gains tax rates for federal income tax purposes.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2022, none qualify for the
corporate dividends received deduction available to corporate shareholders or as
qualified dividend income.

                              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

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                          OCTOBER 31, 2022 (UNAUDITED)

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.

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


                                                                         Page 57

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
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. Market risk is the risk that a particular security, or shares of a
fund in general, may fall in value. 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 COVID-19 global pandemic and the ensuing policies
enacted by governments and central banks have caused and may continue to cause
significant volatility and uncertainty in global financial markets. While the
U.S. has resumed "reasonably" normal business activity, many countries continue
to impose lockdown measures. Additionally, there is no guarantee that vaccines
will be effective against emerging variants of the disease. These events also
adversely affect the prices and liquidity of a fund's portfolio securities or
other instruments and could result in disruptions in the trading markets. Any of
such circumstances could have a materially negative impact on the value of a
fund's shares and result in increased market volatility. During any such events,
a fund's shares may trade at increased premiums or discounts to their net asset
value and the bid/ask spread on a fund's shares may widen.

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.

                          OCTOBER 31, 2022 (UNAUDITED)

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.

PREFERRED SECURITIES RISK. Preferred securities combine some of the
characteristics of both common stocks and bonds. Preferred securities are
typically subordinated to bonds and other debt securities in a company's capital
structure in terms of priority to corporate income, subjecting them to greater
credit risk than those debt securities. Generally, holders of preferred
securities have no voting rights with respect to the issuing company unless
preferred dividends have been in arrears for a specified number of periods, at
which time the preferred security holders may obtain limited rights. In certain
circumstances, an issuer of preferred securities may defer payment on the
securities and, in some cases, redeem the securities prior to a specified date.
Preferred securities may also be substantially less liquid than other
securities, including common stock.

VALUATION RISK. The valuation of certain securities may carry more risk than
that of common stock. Uncertainties in the conditions of the financial markets,
unreliable reference data, lack of transparency and inconsistency of valuation
models and processes may lead to inaccurate asset pricing. A fund may hold
investments in sizes smaller than institutionally sized round lot positions
(sometimes referred to as odd lots). However, third-party pricing services
generally provide evaluations on the basis of institutionally-sized round lots.
If a fund sells certain of its investments in an odd lot transaction, the sale
price may be less than the value at which such securities have been held by the
fund. Odd lots often trade at lower prices than institutional round lots. There
is no assurance that the fund will be able to sell a portfolio security at the
price established by the pricing service, which could result in a loss to the
fund.

                               ADVISORY AGREEMENT

BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF INVESTMENT MANAGEMENT
AGREEMENT

The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the continuation of the
Investment Management Agreement (the "Agreement") with First Trust Advisors L.P.
(the "Advisor") on behalf of the First Trust Low Duration Opportunities ETF (the
"Fund"). The Board approved the continuation of the Agreement for a one-year
period ending June 30, 2023 at a meeting held on June 12-13, 2022. The Board
determined that the continuation of the Agreement is in the best interests of
the Fund in light of the nature, extent and quality of the services provided and
such other matters as the Board considered to be relevant in the exercise of its
business judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law, in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. At meetings held on April 18, 2022 and June 12-13, 2022, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor responding to requests for information from counsel to the Independent
Trustees, submitted on behalf of the Independent Trustees, that, among other
things, outlined: the services provided by the Advisor to the Fund (including
the relevant personnel responsible for these services and their experience); the
unitary fee rate payable by the Fund as compared to fees charged to a peer group
of funds (the "Expense Group") and a broad peer universe of funds (the "Expense
Universe"), each assembled by Broadridge Financial Solutions, Inc.
("Broadridge"), an independent source, and as compared to fees charged to other
clients of the Advisor, including other exchange-traded funds ("ETFs") managed
by the Advisor; the expense ratio of the Fund as compared to expense ratios of
the funds in the Fund's Expense Group and Expense Universe; performance
information for the Fund, including comparisons of the Fund's performance to
that of one or more relevant benchmark indexes and to that of a performance
group of funds and a broad performance universe of funds (the "Performance
Universe"), each assembled by Broadridge; the nature of expenses incurred in
providing services to the Fund and the potential for the Advisor to realize
economies of scale, if any; profitability and other financial data for the
Advisor; any indirect benefits to the Advisor and its affiliate, First Trust
Portfolios L.P. ("FTP"); and information on the Advisor's compliance program.
The Board reviewed initial materials with the Advisor at the meeting held on
April 18, 2022, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the
April meeting, counsel to the Independent Trustees, on behalf of the Independent
Trustees, requested certain clarifications and supplements to the materials
provided, and the information provided in response to those requests was
considered at an executive session of the Independent Trustees and their counsel
held prior to the June 12-13, 2022 meeting, as well as at the June meeting. The
Board applied its business judgment to determine whether the arrangement between
the Trust and the Advisor continues to be a reasonable business arrangement from


                                                                         Page 59

                          OCTOBER 31, 2022 (UNAUDITED)

the Fund's perspective. The Board determined that, given the totality of the
information provided with respect to the Agreement, the Board had received
sufficient information to renew the Agreement. The Board considered that
shareholders chose to invest or remain invested in the Fund knowing that the
Advisor manages the Fund and knowing the Fund's unitary fee.

In reviewing the Agreement, the Board considered the nature, extent and quality
of the services provided by the Advisor under the Agreement. The Board
considered that the Advisor is responsible for the overall management and
administration of the Trust and the Fund and reviewed all of the services
provided by the Advisor to the Fund, as well as the background and experience of
the persons responsible for such services. The Board noted that the Fund is an
actively-managed ETF and noted that the Advisor's Securitized Products Group is
responsible for the day-to-day management of the Fund's investments. The Board
considered the background and experience of the members of the Securitized
Products Group and noted the Board's prior meetings with members of the Group.
The Board considered the Advisor's statement that it applies the same oversight
model internally with its Securitized Products Group as it uses for overseeing
external sub-advisors, including portfolio risk monitoring and performance
review. In reviewing the services provided, the Board noted the compliance
program that had been developed by the Advisor and considered that it includes a
robust program for monitoring the Advisor's and the Fund's compliance with the
1940 Act, as well as the Fund's compliance with its investment objectives,
policies and restrictions. The Board also considered a report from the Advisor
with respect to its risk management functions related to the operation of the
Fund. Finally, as part of the Board's consideration of the Advisor's services,
the Advisor, in its written materials and at the April 18, 2022 meeting,
described to the Board the scope of its ongoing investment in additional
personnel and infrastructure to maintain and improve the quality of services
provided to the Fund and the other funds in the First Trust Fund Complex. In
light of the information presented and the considerations made, the Board
concluded that the nature, extent and quality of the services provided to the
Trust and the Fund by the Advisor under the Agreement have been and are expected
to remain satisfactory and that the Advisor has managed the Fund consistent with
its investment objectives, policies and restrictions.

The Board considered the unitary fee rate payable by the Fund under the
Agreement for the services provided. The Board considered that as part of the
unitary fee the Advisor is responsible for the Fund's expenses, including the
cost of transfer agency, custody, fund administration, legal, audit and other
services and license fees, if any, but excluding the fee payment under the
Agreement and interest, taxes, 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, if any.
The Board received and reviewed information showing the fee rates and expense
ratios of the peer funds in the Expense Group, as well as advisory and unitary
fee rates charged by the Advisor to other fund (including ETFs) and non-fund
clients, as applicable. Because the Fund pays a unitary fee, the Board
determined that expense ratios were the most relevant comparative data point.
Based on the information provided, the Board noted that the unitary fee rate for
the Fund was above the median total (net) expense ratio of the peer funds in the
Expense Group. With respect to the Expense Group, the Board, at the April 18,
2022 meeting, discussed with Broadridge its methodology for assembling peer
groups and discussed with the Advisor limitations in creating peer groups for
actively-managed ETFs, including that the Expense Group contained both
actively-managed ETFs and open-end mutual funds, and different business models
that may affect the pricing of services among ETF sponsors. The Board took these
limitations and differences into account in considering the peer data. With
respect to fees charged to other non-ETF clients, the Board considered
differences between the Fund and other non-ETF clients that limited their
comparability. In considering the unitary fee rate overall, the Board also
considered the Advisor's statement that it seeks to meet investor needs through
innovative and value-added investment solutions and the Advisor's demonstrated
long-term commitment to the Fund and the other funds in the First Trust Fund
Complex.

The Board considered performance information for the Fund. The Board noted the
process it has established for monitoring the Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor for the Fund. The Board determined that this process continues to be
effective for reviewing the Fund's performance. The Board received and reviewed
information comparing the Fund's performance for periods ended December 31, 2021
to the performance of the funds in the Performance Universe and to that of a
benchmark index. Based on the information provided, the Board noted that the
Fund outperformed the Performance Universe median and the benchmark index for
the one-year period ended December 31, 2021 and underperformed the Performance
Universe median and the benchmark index for the three- and five-year periods
ended December 31, 2021.

On the basis of all the information provided on the unitary fee and performance
of the Fund and the ongoing oversight by the Board, the Board concluded that the
unitary fee for the Fund continues to be reasonable and appropriate in light of
the nature, extent and quality of the services provided by the Advisor to the
Fund under the Agreement.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Fund and noted the Advisor's statement that it believes that its expenses
relating to providing advisory services to the Funds will likely increase during
the next twelve months as the Advisor continues to build infrastructure and add
new staff. The Board noted that any reduction in fixed costs associated with the

                          OCTOBER 31, 2022 (UNAUDITED)

management of the Fund would benefit the Advisor, but that the unitary fee
structure provides a level of certainty in expenses for the Fund. The Board
considered the revenues and allocated costs (including the allocation
methodology) of the Advisor in serving as investment advisor to the Fund for the
twelve months ended December 31, 2021 and the estimated profitability level for
the Fund calculated by the Advisor based on such data, as well as complex-wide
and product-line profitability data, for the same period. The Board noted the
inherent limitations in the profitability analysis and concluded that, based on
the information provided, the Advisor's profitability level for the Fund was not
unreasonable. In addition, the Board considered indirect benefits described by
the Advisor that may be realized from its relationship with the Fund. The Board
considered that the Advisor had identified as an indirect benefit to the Advisor
and FTP their exposure to investors and brokers who, absent their exposure to
the Fund, may have had no dealings with the Advisor or FTP, and noted that the
Advisor does not utilize soft dollars in connection with the Fund. The Board
concluded that the character and amount of potential indirect benefits to the
Advisor were not unreasonable.

Based on all of the information considered and the conclusions reached, the
Board, including the Independent Trustees, unanimously determined that the terms
of the Agreement continue to be fair and reasonable and that the continuation of
the Agreement is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.

BOARD CONSIDERATIONS REGARDING APPROVAL OF AMENDMENT TO THE INVESTMENT
MANAGEMENT AGREEMENT

The Board of Trustees of First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the amendment (the
"Amendment") of the Investment Management Agreement (the "Agreement") with First
Trust Advisors L.P. (the "Advisor") on behalf of the First Trust Low Duration
Opportunities ETF (the "Fund").

The Board approved the Amendment at a meeting held on October 24, 2022. As part
of the review process, the Board reviewed information and had preliminary
discussions with the Advisor regarding the proposed Amendment at meetings held
on April 18, 2022, June 12-13, 2022 and September 18-19, 2022. Following those
preliminary discussions, the Board requested and received information from the
Advisor regarding the proposed Amendment, and that information was considered at
an executive session of the Independent Trustees and their counsel held prior to
the October 24, 2022 meeting, as well as at the October meeting.

In reviewing the Amendment, the Board considered that the purpose of the
Amendment is to modify the unitary fee rate for the Fund under the Agreement by
introducing a breakpoint schedule pursuant to which the unitary fee rate paid by
the Fund to the Advisor will be reduced as assets of the Fund meet certain
thresholds. The Board noted the Advisor's representations that the quality and
quantity of the services provided to the Fund by the Advisor under the Agreement
will not be reduced or modified as a result of the Amendment, and that the

and quality of the services provided and such other matters as the Board
considered to be relevant in the exercise of its business judgment.

Based on all of the information considered, the Board, including the Independent
Trustees, unanimously determined that the terms of the Amendment are fair and
reasonable and that the Amendment is in the best interests of the Fund.

                                  REMUNERATION

First Trust Advisors L.P. ("First Trust") is authorised and regulated by the
U.S. Securities and Exchange Commission and is entitled to market shares of
certain funds it manages, including First Trust Low Duration Opportunities ETF
(the "Fund"), in certain member states in the European Economic Area in
accordance with the cooperation arrangements in Article 42 of the Alternative
Investment Fund Managers Directive (the "Directive"). First Trust is required
under the Directive to make disclosures in respect of remuneration. The
following disclosures are made in line with First Trust's interpretation of
currently available regulatory guidance on remuneration disclosures.

During the year ended December 31, 2021, the amount of remuneration paid (or to

$6,508,003 paid (or to be paid) in variable compensation. There were a total of
26 beneficiaries of the remuneration described above. Those amounts include
$1,832,092 paid (or to be paid) to senior management of First Trust Advisors
L.P. and $5,034,172 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors

                                                                         Page 61

ADDITIONAL INFORMATION (CONTINUED)

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                          OCTOBER 31, 2022 (UNAUDITED)

Code Staff included in the aggregated figures disclosed above are rewarded in
line with First Trust's remuneration policy (the "Remuneration Policy") which is
determined and implemented by First Trust's senior management. The Remuneration
Policy reflects First Trust's ethos of good governance and encapsulates the
following principal objectives:

      i.    to provide a clear link between remuneration and performance of
            First Trust and to avoid rewarding for failure;

      ii.   to promote sound and effective risk management consistent with the
            risk profiles of the funds managed by First Trust; and

      iii.  to remunerate staff in line with the business strategy, objectives,
            values and interests of First Trust and the funds managed by First
            Trust in a manner that avoids conflicts of interest.

First Trust assesses various risk factors which it is exposed to when
considering and implementing remuneration for Code Staff and considers whether
any potential award to such person(s) would give rise to a conflict of interest.
First Trust does not reward failure, or consider the taking of risk or failure
to take risk in its remuneration of Code Staff.

First Trust assesses performance for the purposes of determining payments in
respect of performance-related remuneration of Code Staff by reference to a
broad range of measures including (i) individual performance (using financial
and non-financial criteria), and (ii) the overall performance of First Trust.
Remuneration is not based upon the performance of the Fund.

The elements of remuneration are balanced between fixed and variable and the
senior management sets fixed salaries at a level sufficient to ensure that
variable remuneration incentivises and rewards strong individual performance but
does not encourage excessive risk taking.

No individual is involved in setting his or her own remuneration.
