                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS


This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and/or Energy Income Partners, LLC ("EIP" or the
"Sub-Advisor") and their respective representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
any series of First Trust Exchange-Traded Fund IV (the "Trust") described in
this report (each such series is referred to as a "Fund" and collectively, as
the "Funds") to be materially different from any future results, performance or
achievements expressed or implied by the forward-looking statements. When
evaluating the information included in this report, you are cautioned not to
place undue reliance on these forward-looking statements, which reflect the
judgment of the Advisor and/or Sub-Advisor and their respective representatives
only as of the date hereof. We undertake no obligation to publicly revise or

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that any Fund described in this report will achieve its
investment objective. Each 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 a Fund. See "Risk
Considerations" in the Additional Information section of this report for a
discussion of other risks of investing in the Funds.

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.

The Advisor may also periodically provide additional information on Fund
performance on each Fund's webpage at www.ftportfolios.com.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment. It
includes details about each Fund and presents data and analysis that provide
insight into each Fund's performance and investment approach.

By reading the portfolio commentary from the portfolio management team of the
Funds, you may obtain an understanding of how the market environment affected
each Fund's performance. The statistical information that follows may help you

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
North American Energy Infrastructure Fund and the First Trust EIP Carbon Impact
ETF (the "Funds"), which contains detailed information about the Funds for the
twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

(See Notes to Fund Performance Overview on page 6.)

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

(1)   The Blended Benchmark consists of the following two indices: 50% of the
      PHLX Utility Sector Index which is a market capitalization weighted index
      composed of geographically diverse public U.S. utility stocks; and 50% of
      the Alerian MLP Total Return Index which is a float-adjusted,
      capitalization-weighted composite of the 50 most prominent energy Master
      Limited Partnerships (MLPs). Indices are unmanaged and an investor cannot
      invest directly in an index. All index returns assume that distributions
      are reinvested when they are received. The Blended Benchmark returns are
      calculated by using the monthly return of the two indices during each
      period shown above. At the beginning of each month the two indices are
      rebalanced to a 50-50 ratio to account for divergence from that ratio that
      occurred during the course of each month. The monthly returns are then
      compounded for each period shown above, giving the performance for the
      Blended Benchmark for each period shown above.

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 indices do
not actually hold a portfolio of securities and therefore do not incur the
expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS

Information showing the number of days the market price of the Fund's shares was
greater (at a premium) and less (at a discount) than the Fund's net asset value
for the most recently completed year, and the most recently completed calendar
quarters since that year (or life of the Fund, if shorter) is available at
https://www.ftportfolios.com/Retail/etf/home.aspx.

NOTES TO FUND PERFORMANCE OVERVIEW (UNAUDITED)
--------------------------------------------------------------------------------

Total returns for the periods since inception are calculated from the inception
date of each Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the periods indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the periods
indicated.

Each 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 each Fund did
not trade in the secondary market until after the Fund's inception, for the
period from inception to the first day of secondary market trading in shares of
the Fund, the NAV of each 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 each Fund at NAV and Market Price,
respectively.

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

                                   COMMENTARY

FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND

The Fund's investment objective is to seek total return. The Fund pursues its
investment objective by investing, under normal market conditions, at least 80%
of its net assets (including investment borrowings) in equity securities of
companies deemed by EIP to be engaged in the energy infrastructure sector. These
companies principally include publicly traded master limited partnerships and
limited liability companies taxed as partnerships ("MLPs"), MLP affiliates,
pipeline companies, utilities, and other companies that derive the majority of
their revenues from operating or providing services in support of infrastructure
assets such as pipelines, power transmission and petroleum and natural gas
storage in the petroleum, natural gas and power generation industries
(collectively, "Energy Infrastructure Companies"). The Fund will invest
principally in Energy Infrastructure Companies. Under normal market conditions,
the Fund will invest at least 80% of its net assets (including investment
borrowings) in equity securities of companies headquartered or incorporated in
the United States and Canada. There can be no assurance that the Fund's
investment objective will be achieved. The Fund may not be appropriate for all
investors.

MARKET RECAP

As measured by the Alerian MLP Total Return Index (the "MLP Index") and the PHLX
Utility Sector Index (the "UTY Index"), the total return for energy-related MLPs
and utilities for the 12-month period ended October 31, 2020 was -42.52% and
2.69%, respectively. These figures are according to data collected from Alerian
Capital Management and Bloomberg. As measured by the S&P 500(R) Index (the
"Index"), the broader equity market over the same period returned 9.71%.

PERFORMANCE ANALYSIS

On a net asset value ("NAV") basis for the 12-month period ended October 31,
2020, the Fund provided a total return of -16.69%, including the reinvestment of
dividends. This compares, according to collected data, to a total return of
-18.29%(1) for the compounded average of the two indices (the "Blended
Benchmark") (-42.52% for the MLP Index and 2.69% for the UTY Index), and 9.71%
for the S&P 500(R) Index.

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

(1)   The total return is the monthly rebalanced return for the MLP Index and
      UTY Index.

PORTFOLIO COMMENTARY (CONTINUED)
--------------------------------------------------------------------------------

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

The Fund declared quarterly distributions during the fiscal year as follows:
$0.2595 per share in December 2019; $0.2584 per share in March 2020; $0.2813 per
share in June 2020; and $0.2168 per share in September 2020.

The Fund's NAV total return of -16.69% outperformed the -18.29% average return
of the Blended Benchmark. The Fund's outperformance was driven by overweight
positions in utilities and pipeline C-Corporations ("C-Corps ") that were not as
affected by volatile oil prices. The Fund also benefited from its lower overall
MLP exposure compared to the Blended Benchmark that has a 50% weight of MLPs
that underperformed during the period. EIP has sought to consistently run a more
conservative portfolio compared to the Blended Benchmark. This conservatism is
reflected in holding a more diversified set of higher quality companies that
themselves have more conservative balance sheets, more stable cash flows and
lower dividend payout ratios. This more conservative approach to investing in
North American energy infrastructure was the primary driver to the Fund's
outperformance in a volatile market.

MARKET AND FUND OUTLOOK

The first calendar quarter of 2020 was dominated by the dramatic price declines
in the crude oil market due to Saudi and Russian production decisions coupled
with the demand shock related to the coronavirus ("COVID-19") pandemic. These
weak market conditions drove a -21% decline in the Alerian MLP Index between
January 1 and February 28 of 2020, then panic took hold in March driving another
-59% decline by March 18. (Source: Bloomberg) Our analysis indicates that forced
selling by levered closed-end MLP funds was approximately $4.3 billion and
outflows from open-end funds were approximately $0.9 billion in a four-week
period. This is nearly $1 billion more than the selling that occurred over a
9-month period in 2015-2016 due to outflows and de-leveraging when oil prices
corrected from over $100 per barrel, but on assets that were nearly three times
as large as today.

Despite a second quarter rally off the lows of the first quarter, stock price
performance of the Alerian MLP Index and the energy companies in the S&P 500(R)
Index turned negative again in the third quarter of 2020 as near-term
fundamentals for crude oil remained uncertain. At the end of the third quarter
of 2020 the price of crude oil was still down -34% year-to-date and drilling
activity remained near the all-time lows set in August of 2020. Crude oil
production was trending lower in most basins by the end of the third quarter
despite rebounding in the second quarter as shut-in production was brought back
online. Second quarter announcements by oil and gas producers to cut spending
and lay off staff was followed by several third quarter merger announcements.

Slowing investment and negative sentiment in upstream energy, driven by
COVID-related declines in demand, have given rise to a narrative that all
conventional energy businesses are in decline; this is simply wrong, in our
opinion. It is true that coal will likely continue to decline, we believe. In
our view, crude oil and refined products demand will be slow to fully recover
from the pandemic and their long-term growth is threatened by electrification of
large parts of the transportation system, but these businesses represent the
minority of our portfolio. And, the companies exposed to these businesses are
trading at dividend yields and valuations that make their expected rates of
return the highest in our portfolio.

On the other hand, in EIP's opinion, the outlook for electricity and natural
gas, which is the majority of the portfolio, remains strong and is increasingly
aligned with public sentiment and environmental policy. Cheaper sources of
cleaner electricity continue to substitute for coal which is likely to continue
to decline as an energy source, in our view, and to which we have no portfolio
earnings exposure. EIP believes electric and natural gas utilities are
experiencing attractive rates of earnings growth as they invest capital to
incorporate cheaper, cleaner, safer, and more reliable sources of energy. In our
view, the network utilities can increase the value of these new technologies by
integrating them into an intelligent system of shared resources much the way
information networks like cloud computing and the new retail intermediaries like
Amazon and eBay are doing for those parts of the economy. We believe the
transition to a shared resource network favors their incumbency and existing
rights of way, which provides energy cheaper to customers than disconnecting
from these networks by "cutting the cord".

EIP is optimistic about the technological breakthroughs in energy and invests in
companies like renewable developers and network utilities that benefit from the
lower cost and higher performance of renewables, batteries, and other new
grid-related innovations. But EIP is not a venture capitalist; companies in the
Fund's portfolio must have a track record of profitability and a willingness to
share some portion of that profitability through dividends. While the names in
the portfolio change over time, the strategy and the sources of earnings
stability and growth remain the same: investing in monopoly infrastructure that
provides the low-cost way of shipping the lowest cost form of energy.

                          OCTOBER 31, 2020 (UNAUDITED)

FIRST TRUST EIP CARBON IMPACT ETF

The First Trust EIP Carbon Impact ETF's (the "Fund") inception date was August
19, 2019. The Fund's investment objective is to seek to achieve a competitive
risk-adjusted total return balanced between dividends and capital appreciation.
The Fund pursues its investment objective by investing, under normal market
conditions, at least 80% of its net assets (including investment borrowings) in
equity securities of companies identified by EIP as having or seeking to have a
positive carbon impact. EIP defines positive carbon impact companies as
companies that reduce, have a publicly available plan to reduce, or enable the
reduction of carbon and other greenhouse gas ("GHG") emissions from the
production, transportation, conversion, storage and use of energy. The Fund's
investments will be concentrated in the industries constituting the energy
infrastructure sector. These companies principally include: utilities; natural
gas pipeline companies; manufacturers, contracted developers and/or owners of
renewable energy; and other companies that derive the majority of their earnings
from manufacturing, operating or providing services in support of infrastructure
assets and/or infrastructure activities such as renewable energy equipment,
energy storage, carbon capture and sequestration, fugitive methane abatement and
energy transmission and distribution equipment. The Fund will generally not
invest in companies comprising the following industries: coal production, oil
exploration and production, or crude oil storage, transportation and delivery.
The Fund's portfolio will be principally composed of equity securities,
including common stock, depositary receipts, and units issued by master limited
partnerships ("MLPs"). Such securities may be issued by small, mid and large
capitalization companies operating in developed market countries.

MARKET RECAP

As measured by the S&P 500(R) Index (the "Index") and the PHLX Utility Sector
Index (the "UTY Index"), the total return for energy-related MLPs and utilities
for the 12-month period ended October 31, 2020 was 9.71% and 2.69%,
respectively. These figures are according to data collected from Bloomberg.

PERFORMANCE ANALYSIS

On a net asset value ("NAV") basis for the 12-month period ended October 31,
2020, the Fund provided a total return of 5.69%, including the reinvestment of
dividends. The Fund's NAV total return of 5.69% underperformed the Index by 402
basis points ("bps") and outperformed the UTY Index by 300 bps. The Fund
declared quarterly distributions during the fiscal year as follows: $0.15 per
share in December 2019; $0.0599 per share in March 2020; $0.1142 per share in
June 2020; and $0.1224 per share in September 2020.

Outperformance of the Fund relative to the UTY was partially driven by stronger
earnings expectations relative to the UTY. EIP believes that rapidly evolving
state and federal energy policies and regulations, paired with technological
innovation, continue to drive the transition to an energy system that is safer,
cleaner and more reliable. EIP also believes investors in regulated utilities,
renewable developers and other energy infrastructure companies have an
opportunity to participate in these dramatic changes. EIP is optimistic that
companies involved in activities aimed at reducing carbon and other Greenhouse
Gas (GHG) emissions have good growth potential.

MARKET AND FUND OUTLOOK

In EIP's opinion, the outlook for electricity and natural gas, which is the
majority of the portfolio, remains strong and is increasingly aligned with
public sentiment and environmental policy. Cheaper sources of cleaner
electricity continue to substitute for coal which is likely to continue to
decline as an energy source, in our view, and to which we have no portfolio

FIRST TRUST EXCHANGE-TRADED FUND IV

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (UNAUDITED)

As a shareholder of First Trust North American Energy Infrastructure Fund or
First Trust EIP Carbon Impact ETF (each a "Fund" and collectively, the "Funds"),
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 Funds 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, 2020.

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 each Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
each 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 Funds 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)   This security is exempt from registration upon resale under Rule 144A of
      the Securities Act of 1933, as amended (the "1933 Act") and may be resold
      in transactions exempt from registration, normally to qualified
      institutional buyers. This security is not restricted on the foreign
      exchange where it trades freely without any additional registration. As
      such, it does not require the additional disclosure required of restricted
      securities.

(b)   This security may be resold to qualified foreign investors and foreign
      institutional buyers under Regulation S of the 1933 Act.

(c)   This security is fair valued by the Advisor's Pricing Committee in
      accordance with procedures adopted by the Trust's Board of Trustees, and
      in accordance with provisions of the Investment Company Act of 1940, as
      amended. At October 31, 2020, securities noted as such are valued at
      $53,268 or 2.5% of net assets. Certain of these securities are fair valued
      using a factor provided by a third-party pricing service due to the change
      in value between the foreign markets' close and the New York Stock
      Exchange ("NYSE") close exceeding a certain threshold. On days when this
      threshold is not exceeded, these securities are typically valued at the
      last sale price on the exchange on which they are principally traded.

(d)   Non-income producing security.

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the two funds listed below. The shares of each fund are listed and traded
on the NYSE Arca, Inc. ("NYSE Arca").

    First Trust North American Energy Infrastructure Fund - (NYSE Arca ticker
       "EMLP")
    First Trust EIP Carbon Impact ETF - (NYSE Arca ticker "ECLN")

Each fund represents a separate series of shares of beneficial interest in the
Trust (each a "Fund" and collectively, the "Funds"). Unlike conventional mutual
funds, each Fund issues and redeems shares on a continuous basis, at net asset
value ("NAV"), only in large specified blocks consisting of 50,000 shares called
a "Creation Unit." Each Fund's Creation Units are generally issued and redeemed
in-kind for securities in which the Fund invests and, in certain circumstances,
for cash, and only to and from broker-dealers and large institutional investors
that have entered into participation agreements. Except when aggregated in
Creation Units, each Fund's shares are not redeemable securities.

Each Fund is an actively managed exchange-traded fund. EMLP's investment
objective is to seek total return. EMLP will invest, under normal market
conditions, at least 80% of its net assets (including investment borrowings) in
equity securities of companies deemed by Energy Income Partners, LLC ("EIP" or
the "Sub-Advisor") to be engaged in the energy infrastructure sector, which
principally include publicly-traded master limited partnerships and limited
liability companies taxed as partnerships ("MLPs"), MLP affiliates, pipeline
companies, utilities, and other companies that derive the majority of their
revenues from operating or providing services in support of infrastructure
assets such as pipelines, power transmission and petroleum and natural gas
storage in the petroleum, natural gas and power generation industries
(collectively, "Energy Infrastructure Companies"). In addition, under normal
market conditions, the Fund will invest at least 80% of its net assets
(including investment borrowings) in equity securities of companies
headquartered or incorporated in the United States and Canada. ECLN's investment
objective is to seek to achieve a competitive risk-adjusted total return
balanced between dividends and capital appreciation. ECLN will invest, under
normal market conditions, at least 80% of its net assets (including investment
borrowings) in equity securities of companies identified by EIP as having or
seeking to have a positive carbon impact, defined as companies that reduce, have
a publicly available plan to reduce, or enable the reduction of carbon and other
greenhouse gas emissions from the production, transportation, conversion,
storage and use of energy. ECLN's investments will be concentrated in the
industries constituting the energy infrastructure sector, which principally
include utilities, natural gas pipeline companies, manufacturers, contracted
developers and/or owners of renewable energy, and other companies that derive
the majority of their earnings from manufacturing, operating or providing
services in support of infrastructure assets and/or infrastructure activities
such as renewable energy equipment, energy storage, carbon capture and
sequestration, fugitive methane abatement and energy transmission and
distribution equipment.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Funds are each considered an investment company and follow 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 Funds 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

Each 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. Foreign securities are priced using data
reflecting the earlier closing of the principal markets for those securities.
Each Fund's NAV is calculated by dividing the value of all assets of each Fund
(including accrued interest and dividends), less all liabilities (including
accrued expenses and dividends declared but unpaid), by the total number of
shares outstanding.


                                                                         Page 19

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                                OCTOBER 31, 2020

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

      Common stocks, MLPs and other equity securities listed on any national or
      foreign exchange (excluding The Nasdaq Stock Market LLC ("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 principal market for such securities.

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

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

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

      1)    the type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or third-party pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

If the securities in question are foreign securities, the following additional
information may be considered:

      1)    the value of similar foreign securities traded on other foreign
            markets;

      2)    ADR trading of similar securities;

      3)    closed-end fund or exchange-traded fund trading of similar
            securities;

      4)    foreign currency exchange activity;

      5)    the trading prices of financial products that are tied to baskets of
            foreign securities;

      6)    factors relating to the event that precipitated the pricing problem;

      7)    whether the event is likely to recur; and

      8)    whether the effects of the event are isolated or whether they affect
            entire markets, countries or regions.

Because foreign markets may be open on different days than the days during which
investors may transact in the shares of a Fund, the value of the Fund's
securities may change on the days when investors are not able to transact in the
shares of the Fund. The value of securities denominated in foreign currencies is
converted into U.S. dollars using exchange rates determined daily as of the
close of regular trading on the NYSE.

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                                OCTOBER 31, 2020

The Funds are 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 each Fund's investments as of October 31, 2020, is
included with each Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income, if any, is
recorded on the accrual basis.

Distributions received from a Fund's investments in MLPs generally are comprised
of return of capital and investment income. A Fund records estimated return of
capital and investment income based on historical information available from
each MLP. These estimates may subsequently be revised based on information
received from the MLPs after their tax reporting periods are concluded.

C. FOREIGN CURRENCY

The books and records of the Funds are maintained in U.S. dollars. Foreign
currencies, investments and other assets and liabilities are translated into
U.S. dollars at the exchange rates prevailing at the end of the period.
Purchases and sales of investments and items of income and expense are
translated on the respective dates of such transactions. Unrealized gains and
losses on assets and liabilities, other than investments in securities, which
result from changes in foreign currency exchange rates have been included in
"Net change in unrealized appreciation (depreciation) on foreign currency
translation" on the Statements of Operations. Unrealized gains and losses on
investments in securities which result from changes in foreign exchange rates
are included with fluctuations arising from changes in market price and are
shown in "Net change in unrealized appreciation (depreciation) on investments"
on the Statements of Operations. Net realized foreign currency gains and losses
include the effect of changes in exchange rates between trade date and
settlement date on investment security transactions, foreign currency
transactions and interest and dividends received and is included in "Net
realized gain (loss) on foreign currency transactions" on the Statements of
Operations. The portion of foreign currency gains and losses related to
fluctuations in exchange rates between the initial purchase settlement date and
subsequent sale trade date is included in "Net realized gain (loss) on
investments" on the Statements of Operations.

D. DIVIDENDS AND DISTRIBUTION TO SHAREHOLDERS

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

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 significantly modified portfolio securities
held by the Funds 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.


                                                                         Page 21

E. INCOME TAXES

Each 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, each Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of each Fund's taxable income
exceeds the distributions from such taxable income for the calendar year.

Each 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.
Each 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, 2020, EMLP
and ECLN had non-expiring capital loss carryforwards available for federal
income tax purposes of $445,337,693 and $7,613, respectively.

The Funds are 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. For EMLP, the taxable years ended
2017, 2018, 2019, and 2020 remain open to federal and state audit. For ECLN, the
taxable years ended 2019 and 2020 remain open to federal and state audit. As of
October 31, 2020, management has evaluated the application of these standards to
the Funds and has determined that no provision for income tax is required in the
Funds' financial statements for uncertain tax positions.

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, 2020, the Funds had
no net late year ordinary 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 Statements 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 Funds and in-kind transactions. The results of
operations and net assets were not affected by these adjustments. For the fiscal

F. EXPENSES

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

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

First Trust, the investment advisor to the Funds, 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 ongoing monitoring of the securities in each Fund's
portfolio, managing the Funds' business affairs and providing certain
administrative services necessary for the management of the Funds.

The Trust, on behalf of the Funds, and First Trust have retained EIP, an
affiliate of First Trust, to serve as the Funds' investment sub-advisor. In this
capacity, EIP is responsible for the selection and ongoing monitoring of the
securities in each Fund's investment portfolio. Pursuant to the Investment
Management Agreement between the Trust and the Advisor, First Trust will
supervise EIP and its management of the investment of each Fund's assets and
will pay EIP for its services as the Funds' sub-advisor. First Trust will also
be responsible for each Fund's expenses, including the cost of transfer agency,
custody, fund administration, legal, audit and other services, but excluding fee
payments under the Investment Management Agreement, interest, taxes, acquired
fund fees and expenses, if any, 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.
Each Fund has agreed to pay First Trust an annual unitary management fee equal
to 0.95% of its average daily net assets. EIP receives a sub-advisory fee for
EMLP from First Trust equal to 45% of any remaining monthly investment
management fee paid to First Trust after the Fund's average Fund expenses
accrued during the most recent twelve months are subtracted from the investment
management fee in a given month. EIP receives a sub-advisory fee for ECLN from
First Trust equal to an annual rate of 0.475% of the Fund's average daily net
assets less one-half of the Fund's expenses, for which EIP is responsible.

First Trust Capital Partners, LLC ("FTCP"), an affiliate of First Trust, owns,
through a wholly-owned subsidiary, a 15% ownership interest in each of EIP and
EIP Partners, LLC, an affiliate of EIP.

The Trust has multiple service agreements with The Bank of New York Mellon
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
each Fund. As custodian, BNYM is responsible for custody of each Fund's assets.
As fund accountant and administrator, BNYM is responsible for maintaining the
books and records of each Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for each 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 defined-outcome fund or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen 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
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Trust for acting in such capacities.


                                                                         Page 23

</TABLE>


                 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by each Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). In order to purchase Creation Units of each Fund, an
Authorized Participant must deposit (i) a designated portfolio of equity
securities determined by First Trust (the "Deposit Securities") and generally
make or receive a cash payment referred to as the "Cash Component," which is an
amount equal to the difference between the NAV of the Fund Shares (per Creation
Unit Aggregation) and the market value of the Deposit Securities, and/or (ii)
cash in lieu of all or a portion of the Deposit Securities. If the Cash
Component is a positive number (i.e., the NAV per Creation Unit Aggregation
exceeds the Deposit Amount), the Authorized Participant will deliver the Cash
Component. If the Cash Component is a negative number (i.e., the NAV per
Creation Unit Aggregation is less than the Deposit Amount), the Authorized
Participant will receive the Cash Component. Authorized Participants purchasing
Creation Units must pay to BNYM, as transfer agent, a creation transaction fee
(the "Creation Transaction Fee") regardless of the number of Creation Units
purchased in the transaction. The Creation Transaction Fee may increase or
decrease with changes in each Fund's portfolio. The price for each Creation Unit
will equal the daily NAV per share 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 or stamp taxes. When a Fund permits an Authorized
Participant to substitute cash or a different security in lieu of depositing one
or more of the requisite Deposit Securities, the Authorized Participant may also
be assessed an amount to cover the cost of purchasing the Deposit Securities
and/or disposing of the substituted securities, including 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 such Deposit
Securities and/or substitute securities.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in each Fund's
portfolio. Each Fund reserves the right to effect redemptions in cash. An
Authorized Participant may request cash redemption in lieu of securities;
however, a Fund may, in its discretion, reject any such request.

                              6. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Funds are
authorized to pay an amount up to 0.25% of their average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Funds, 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 Funds, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before March 31, 2022 for EMLP,
and August 14, 2021 for ECLN.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

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

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 statements of assets and liabilities of First
Trust North American Energy Infrastructure Fund and First Trust EIP Carbon
Impact ETF (the "Funds"), each a series of the First Trust Exchange-Traded Fund
IV, including the portfolios of investments, as of October 31, 2020, the related
statements of operations for the year then ended, the statements of changes in
net assets and the financial highlights for the periods indicated in the table
below, and the related notes. In our opinion, the financial statements and
financial highlights present fairly, in all material respects, the financial
position of each of the Funds as of October 31, 2020, and the results of their
operations for the year then ended, and the changes in their net assets and the
financial highlights for the periods listed in the table below in conformity
with accounting principles generally accepted in the United States of America.

</TABLE>


BASIS FOR OPINION

These financial statements and financial highlights are the responsibility of
the Funds' management. Our responsibility is to express an opinion on the Funds'
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 Funds 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 Funds are not
required to have, nor were we engaged to perform, an audit of their 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 Funds' 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, 2020, 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
reasonable basis for our opinion.

                              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 large
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
not concentrated.

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.


                                                                         Page 27

ADDITIONAL INFORMATION (CONTINUED)
--------------------------------------------------------------------------------

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                          OCTOBER 31, 2020 (UNAUDITED)

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.

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

                          OCTOBER 31, 2020 (UNAUDITED)

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. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, could result in losses to
the fund.

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

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                      ADVISORY AND SUB-ADVISORY AGREEMENTS

BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF INVESTMENT MANAGEMENT
AND SUB-ADVISORY AGREEMENTS

FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND

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 "Advisory Agreement") with First Trust
Advisors L.P. (the "Advisor") on behalf of the First Trust North American Energy
Infrastructure Fund (the "Fund") and the Investment Sub-Advisory Agreement (the
"Sub-Advisory Agreement" and together with the Advisory Agreement, the
"Agreements") among the Trust, on behalf of the Fund, the Advisor and Energy
Income Partners, LLC (the "Sub-Advisor"). The Board approved the continuation of
the Agreements for a one-year period ending June 30, 2021 at a meeting held on
June 8, 2020. The Board determined that the continuation of the Agreements 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 reasonable business judgment.


                                                                         Page 29

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                          OCTOBER 31, 2020 (UNAUDITED)

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 May 11, 2020 and June 8, 2020, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor and the Sub-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 and the
Sub-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 sub-advisory fee rate
as compared to fees charged to other clients of the Sub-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 and the Sub-Advisor to realize economies of
scale, if any; profitability and other financial data for the Advisor; financial
data for the Sub-Advisor; any fall-out benefits to the Advisor and its
affiliates, First Trust Portfolios L.P. ("FTP") and First Trust Capital
Partners, LLC ("FTCP"), and the Sub-Advisor; and information on the Advisor's
and the Sub-Advisor's compliance programs. The Board reviewed initial materials
with the Advisor at the meeting held on May 11, 2020, prior to which the
Independent Trustees and their counsel met separately to discuss the information
provided by the Advisor and the Sub-Advisor. Following the May 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 8, 2020 meeting, as well as at the meeting held that day. The Board
considered supplemental information provided by the Advisor and the Sub-Advisor
on the operations of the Advisor and the Sub-Advisor, respectively, and the
performance of the Fund since the onset of the COVID-19 pandemic. The Board
applied its business judgment to determine whether the arrangements between the
Trust and the Advisor and among the Trust, the Advisor and the Sub-Advisor
continue to be reasonable business arrangements from the Fund's perspective. The
Board determined that, given the totality of the information provided with
respect to the Agreements, the Board had received sufficient information to
renew the Agreements. The Board considered that shareholders chose to invest or
remain invested in the Fund knowing that the Advisor and the Sub-Advisor manage
the Fund and knowing the Fund's unitary fee.

In reviewing the Agreements, the Board considered the nature, extent and quality
of the services provided by the Advisor and the Sub-Advisor under the
Agreements. With respect to the Advisory 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, including the oversight of the Sub-Advisor, as well as the background
and experience of the persons responsible for such services. The Board noted
that the Advisor oversees the Sub-Advisor's day-to-day management of the Fund's
investments, 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, the Sub-Advisor's and the Fund's compliance with
the 1940 Act, as well as the Fund's compliance with its investment objective,
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 May 11, 2020 meeting, described
to the Board the scope of its ongoing investment in additional infrastructure
and personnel to maintain and improve the quality of services provided to the
Fund and the other funds in the First Trust Fund Complex. With respect to the
Sub-Advisory Agreement, the Board noted that the Fund is an actively-managed ETF
and the Sub-Advisor actively manages the Fund's investments. In addition to the
written materials provided by the Sub-Advisor, at the June 8, 2020 meeting, the
Board also received a presentation from representatives of the Sub-Advisor
discussing the services that the Sub-Advisor provides to the Fund, including the
Sub-Advisor's day-to-day management of the Fund's investments. In considering
the Sub-Advisor's management of the Fund, the Board noted the background and
experience of the Sub-Advisor's portfolio management team. 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 and the Sub-Advisor under the Agreements have been and are expected
to remain satisfactory and that the Sub-Advisor, under the oversight of the
Advisor, has managed the Fund consistent with its investment objective, policies
and restrictions.

                      FIRST TRUST EXCHANGE-TRADED FUND IV
                          OCTOBER 31, 2020 (UNAUDITED)

The Board considered the unitary fee rate payable by the Fund under the Advisory
Agreement for the services provided. The Board noted that the sub-advisory fee
is paid by the Advisor from the unitary fee. The Board considered that as part
of the unitary fee the Advisor is responsible for the Fund's expenses, including
the cost of sub-advisory, transfer agency, custody, fund administration, legal,
audit and other services and license fees, if any, but excluding the fee payment
under the Advisory 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 advisory 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
and the Sub-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
below the median total (net) expense ratio of the peer funds in the Expense
Group. With respect to the Expense Group, the Board, at the May 11, 2020
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 also noted
that not all peer funds employ an advisor/sub-advisor management structure. 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 and Sub-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, 2019 to the performance of the funds in the Performance
Universe and to that of a blended benchmark index. Based on the information
provided, the Board noted that the Fund outperformed the Performance Universe
median for the one-, three- and five-year periods ended December 31, 2019. The
Board also noted that the Fund outperformed the blended benchmark index for the
one- and five-year periods ended December 31, 2019 but underperformed the
blended benchmark for the three-year period ended December 31, 2019.

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 (out of which the Sub-Advisor is compensated) continues
to be reasonable and appropriate in light of the nature, extent and quality of
the services provided by the Advisor and the Sub-Advisor to the Fund under the
Agreements.

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board noted that FTCP has an ownership
interest in the Sub-Advisor and considered potential fall-out benefits to the
Advisor from such ownership interest. The Board also considered that the Advisor
had identified as a fall-out 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. The Board concluded that the character and
amount of potential fall-out benefits to the Advisor were not unreasonable.

The Board considered that the Sub-Advisor's investment services expenses are
primarily fixed in nature, and that the Sub-Advisor has made recent investments
in personnel and infrastructure and anticipates that its expenses will continue
to rise due to additions to personnel and system upgrades. The Board did not
review the profitability of the Sub-Advisor with respect to the Fund. The Board
noted that the Advisor pays the Sub-Advisor from the unitary fee and its
understanding that the Fund's sub-advisory fee rate was the product of an arm's


                                                                         Page 31

length negotiation. The Board concluded that the profitability analysis for the
Advisor was more relevant. The Board considered fall-out benefits that may be
realized by the Sub-Advisor from its relationship with the Fund, including
soft-dollar arrangements, and considered a summary of such arrangements. The
Board also considered the potential fall-out benefits to the Sub-Advisor from
the ownership interest of FTCP in the Sub-Advisor. The Board concluded that the
character and amount of potential fall-out benefits to the Sub-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 Agreements continue to be fair and reasonable and that the continuation
of the Agreements is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.

                                  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 First Trust Exchanged-Traded Fund IV funds it manages (the "Funds"), 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, 2019, the amount of remuneration paid (or to
be paid) by First Trust Advisors L.P. in respect of the Funds is $957,969. This
figure is comprised of $59,477 paid (or to be paid) in fixed compensation and
$898,492 paid (or to be paid) in variable compensation. There were a total of 15
beneficiaries of the remuneration described above. Those amounts include
$559,433 paid (or to be paid) to senior management of First Trust Advisors L.P.
and $398,536 paid (or to be paid) to other employees whose professional
activities have a material impact on the risk profiles of First Trust Advisors
L.P. or the Funds (collectively, "Code Staff").

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 Funds.

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.

                          OCTOBER 31, 2020 (UNAUDITED)

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Funds primarily hold assets that
are highly liquid investments, the Funds have not adopted any highly liquid
investment minimums.

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


                                                                         Page 33

                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS


This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
the series of First Trust Exchange-Traded Fund IV (the "Trust") described in
this report (First Trust Senior Loan Fund; hereinafter referred to as the
"Fund") to be materially different from any future results, performance or
achievements expressed or implied by the forward-looking statements. When
evaluating the information included in this report, you are cautioned not to
place undue reliance on these forward-looking statements, which reflect the
judgment of the Advisor and its representatives only as of the date hereof. We
undertake no obligation to publicly revise or update these forward-looking
statements to reflect events and circumstances that arise after the date hereof.

                        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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment in
the Fund. It includes details about the Fund and presents data and analysis that
provide insight into the Fund's performance and investment approach.

By reading the portfolio commentary from the portfolio management team of the
Fund, you may obtain an understanding of how the market environment affected the
Fund's performance. The statistical information that follows may help you
understand the Fund's performance compared to that of relevant market
benchmarks.

It is important to keep in mind that the opinions expressed by personnel of the
Advisor are just that: informed opinions. They should not be considered to be
promises or advice. The opinions, like the statistics, cover the period through
the date on the cover of this report. The material risks of investing in the
Fund are spelled out in the prospectus, the statement of additional information,
and other Fund regulatory filings.

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

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Senior Loan Fund (the "Fund"), which contains detailed information about the
Fund for the twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

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

FIRST TRUST SENIOR LOAN FUND (FTSL)

The First Trust Senior Loan Fund's (the "Fund") primary investment objective is
to provide high current income. The Fund's secondary investment objective is the
preservation of capital. Under normal market conditions, the Fund seeks to
outperform each of the S&P/LSTA U.S. Leveraged Loan 100 Index and the Markit
iBoxx USD Liquid Leveraged Loan Index by investing at least 80% of its net
assets (including investment borrowings) in first lien senior floating rate bank
loans ("Senior Loans"). The S&P/LSTA U.S. Leveraged Loan 100 Index (the "Primary
Index") is a market value-weighted index designed to measure the performance of
the largest segment of the U.S. syndicated leveraged loan market. The Primary
Index consists of 100 loan facilities drawn from a larger benchmark, the
S&P/LSTA Leveraged Loan Index. The Markit iBoxx USD Liquid Leveraged Loan Index
(the "Secondary Index") selects the 100 most liquid Senior Loans in the market.
The Fund does not seek to track either the Primary or Secondary Index, but
rather seeks to outperform each of the Indices. It is anticipated that the Fund,
in accordance with its principal investment strategy, will invest approximately
50% to 75% of its net assets in Senior Loans that are eligible for inclusion in
and meet the liquidity thresholds of the Primary and/or the Secondary Indices at
the time of investment.

A Senior Loan is an advance or commitment of funds made by one or more banks or
similar financial institutions to one or more corporations, partnerships or
other business entities and typically pays interest at a floating or adjusting
rate that is determined periodically at a designated premium above a base
lending rate, most commonly the London Interbank Offered Rate ("LIBOR").

The Fund invests primarily in Senior Loans that are below investment grade
quality at the time of investment. Securities rated below investment grade,
commonly referred to as "junk" or "high-yield" securities, include securities
that are rated Ba1/BB+/BB+ or below by Moody's Investors Service, Inc., Fitch,
Inc., or Standard & Poor's Ratings Group, respectively. The Fund invests in
Senior Loans made predominantly to businesses operating in North America, but
may also invest in Senior Loans made to businesses operating outside of North
America. The Senior Loans included in the Fund's portfolio often maintain a
duration of less than 90 days; however, the inclusion of LIBOR floors on certain
Senior Loans or other factors may cause interest rate duration to be longer than
90 days. The Fund may also invest up to 20% of its net assets in (1) non-Senior
Loan debt securities, which may be fixed-rate or floating-rate income-producing
securities (including, without limitation, U.S. government debt securities and
corporate debt securities which may include convertible bonds), (2) warrants,
U.S. and non U.S. equity and equity-like positions and interests and other
securities issued by or with respect to a borrower or its affiliates, and/or (3)
securities of other investment companies.

</TABLE>


Total returns for the period since inception are calculated from the inception
date of the Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the period indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the period
indicated.

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

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

expenses incurred by the Fund. These expenses negatively impact the performance
of the Fund. The Fund's past performance does not predict future performance.

                                   COMMENTARY

The First Trust Senior Loan Fund (the "Fund") is an actively managed
exchanged-traded fund ("ETF"). The Fund's primary investment objective is to
provide high current income, with a secondary objective of preservation of
capital.

MARKET RECAP

As we ended 2019, the Federal Reserve (the "Fed") had cut interest rates for the
last time in October 2019 and in December indicated that no action would be
likely in 2020 given the persistently low inflation environment. In January
2020, the United States and China signed "Phase One" of a trade agreement, and
U.S. economic data remained strong. The combination of a patient Fed, improving
U.S.- China trade relations, and a robust domestic economy propelled the S&P
500(R) Index to new highs in late February 2020. Shortly after, as the
coronavirus ("COVID-19") pandemic gripped the world's attention, the financial
market implications from the onset of the resulting global economic shutdown
became clear. Equities experienced their most rapid sell-off since the global
financial crisis in 2008. By March 23, 2020 the S&P 500(R) Index was down nearly
34% from its all-time high set on February 19, 2020. Policy makers then took
unprecedented steps to stabilize the markets. Central Banks around the world cut
interest rates and governments announced aggressive monetary stimulus packages.
Domestically, the CARES Act was passed and signed into law on March 27. The bill
included a historic $2 trillion stimulus package aimed at sending financial aid
to struggling U.S. citizens and businesses affected by COVID-19. The Fed also
cut the target Fed Funds rate by 150 basis points ("bps") during the month of
March. As fears subsided, and optimism that the combination of a re-opening of
the U.S. economy and aggressive fiscal and monetary stimulus would result in a
quicker than expected recovery, markets surpassed pre-pandemic levels before a
resurgence in COVID-19 infections tempered investor optimism at the end of the
12-month period ended October 31, 2020.

Senior Loan Market

Senior loan spreads over 3-month London Interbank Offered Rate ("LIBOR")
increased 70 bps during the 12-month period ended October 31, 2020, to L+585
bps. This is above the long-term average spread of L+518 (December 1997 -
October 2020). Retail senior loan funds have experienced 25 consecutive monthly
outflows with demand impacted by the dramatic decrease of the 3-month LIBOR rate
during the same period.

Single-B rated senior loans outperformed both higher and lower quality senior
loans during the same period, returning 3.13% while BB rated issues returned
-0.60%. Single Bs also outperformed CCC rated issues which returned -1.41%
during the same period. The average price of senior loans in the market
decreased from $95.42 in the beginning of the period to $93.17 at the end of the
period.

Default Rates

During the 12-month period ended October 31, 2020, default rates increased
within the S&P/LSTA Leveraged Loan Index. The senior loan market default rate
ended the period at 4.11% compared to the 1.43% rate at the beginning of the
period. The default rate in the senior loan market is above the long-term
average default rate of 2.90%. Looking forward, we anticipate senior loan market
default rates to remain above the long-term averages through 2021 but anticipate
a decline in the default rate as the economy recovers and the introduction of a
vaccine brings a recovery to the industries most impacted by COVID-19.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

FUND PERFORMANCE

The Fund returned 0.90% on a net asset value ("NAV") basis and 0.95% on a market
price basis over the 12-month period ended October 31, 2020. The S&P/LSTA U.S.
Leveraged Loan 100 Index ("the Index") returned 1.52% over the same period.

The Fund held 149 individual positions diversified across 29 industries at the
end of the reporting period. Software (19.51%), Health Care Providers & Services
(16.92%), and Insurance (10.84%) were the Fund's top three industry exposures at
the end of the period. By comparison, the Fund held 194 individual positions
across 33 industries as of October 31, 2019. The Fund modestly decreased its
allocation to high-yield bonds from 8.89% to 8.03% throughout the period, an 86
bps decrease. The Fund's duration remained low throughout the period and
modestly increased from 0.39 years at the beginning of the period to 0.43 years
at the end of the period.

During the last twelve months ("LTM") the Fund's performance significantly
benefited from its overweight position and asset selection in the healthcare
industry. Within the healthcare industry, the Fund's overweight position in a
healthcare cost management solutions company and a healthcare services company
both outperformed the broader healthcare industry. The healthcare industry is
expected to benefit from a divided government, which we believe will result in
no major healthcare legislation or significant changes to the regulatory
environment. Moreover, we anticipate a continued recovery to healthcare volumes,
which are based on billable patient encounters, as the economy continues to
recover from COVID-19. In addition, the Fund benefited from not having an
allocation to the oil & gas industry. The oil & gas industry was one of the
worst performing industries in the Index during the period. The average weight
of the industry in the Index during the LTM period was 2.80%. The underweight
allocation during a period of declining energy prices was significantly
accretive to relative returns. The Fund's overweight position in the
pharmaceutical industry and asset selection in the electronics/electrical
(technology) industry were also notable contributors to the Fund's performance
during the LTM period. Primarily driving the Fund's pharmaceutical industry
contribution was the Fund's overweight position in several pharmaceutical
companies that significantly outperformed the broader pharmaceutical industry
during the LTM period. Finally, primarily driving the Fund's
electronics/electrical (technology) industry outperformance was the Fund's
overweight position in a software services company that outperformed the broader
electronics/electrical (technology) industry during the LTM period. The Fund's
underweight position in a travel technology company that had a large negative
return during the LTM period due to the pandemic's ramifications on the travel
industry also contributed to the Fund's outperformance during the LTM period.

Modestly offsetting these contributors were the Fund's holdings within the
leisure, chemicals & plastics, and building & development industries, due to
asset selection. The primary driver of the leisure industry underperformance was
the Fund's overweight exposure to movie theaters. Movie theaters continue to
face headwinds as new movie releases have been pushed further out on the
calendar as the industry awaits a COVID-19 vaccine.

The Fund's most recent monthly distribution of $0.127 per share is $0.043 per
share lower than the distribution paid in October 2019. Over the LTM period,
3-month LIBOR dropped 168 bps from 1.90% to 0.22% at the end of October 2020,
and distributions followed suit. At the end of the period, the effective yield
based on the distributions for the trailing twelve months was 3.71% based on
NAV.

The Fund experienced two defaults during the LTM period. This compared to 53
defaults within the S&P/LSTA Leveraged Loan Index during the LTM period. Since
inception, the Fund has experienced nine defaults, which compares to 139 within
the broad S&P/LSTA Leveraged Loan Index during the same period. The Fund's LTM
default rate was 1.63% at October 31, 2020. The S&P/LSTA Leveraged Loan Index
default rate was 4.11%.

MARKET AND FUND OUTLOOK

We believe senior loans are supported by spreads that remain in line with the
long-term average, opportunistic pockets of value across ratings and industries,
a low interest rate environment and an improving U.S. economy. Moreover, while
the default rate has increased during the period, we believe individual credits
that came into the 2020 recession with too much leverage, and sectors most
impacted by COVID-19, will face a higher likelihood of default including, but
not limited to energy, travel, leisure and retail, in no particular order.
However, generally, businesses that haven't been impacted by COVID-19 continue
to perform well, in our opinion.

We remain confident that improving economic conditions, unprecedented support
from the Fed, and the potential for additional stimulus will provide a backdrop
for continued recovery in senior loans, in our view. As we evaluate new
investment opportunities, decisions will continue to be rooted in our rigorous
bottom-up credit analysis and our focus will remain on identifying the
opportunities that we believe offer the best risk and reward balance.

FIRST TRUST SENIOR LOAN FUND (FTSL)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (UNAUDITED)

As a shareholder of First Trust Senior Loan Fund (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, 2020.

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)   Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund
      invests generally pay interest at rates which are periodically
      predetermined by reference to a base lending rate plus a premium. These
      base lending rates are generally (i) the lending rate offered by one or
      more major European banks, such as the LIBOR, (ii) the prime rate offered
      by one or more United States banks or (iii) the certificate of deposit
      rate. Certain Senior Loans are subject to a LIBOR floor that establishes a
      minimum LIBOR rate. When a range of rates is disclosed, the Fund holds
      more than one contract within the same tranche with identical LIBOR
      period, spread and floor, but different LIBOR reset dates.

(b)   Senior Loans generally are subject to mandatory and/or optional
      prepayment. As a result, the actual remaining maturity of Senior Loans may
      be substantially less than the stated maturities shown.

(c)   This issuer has filed for protection in bankruptcy court.

(d)   The issuer may pay interest on the loans (1) entirely in cash or (2) in
      the event that both the Payment-In-Kind ("PIK") Toggle Condition has been
      satisfied and the issuer elects to exercise the PIK interest, 2.50%
      payable in cash and 7.00% payable as PIK interest. The first interest
      payment is scheduled for January 4, 2021.

(e)   On October 1, 2020, Akorn Holding Company LLC completed a Bankruptcy Plan
      of Reorganization. In connection with the Plan of Reorganization, the Fund
      received a portion of a new exit term loan and a share of the newly issued
      common equity shares in the re-organized company.

(f)   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 adopted by the Trust's Board of Trustees, this security has
      been determined to be liquid by First Trust Advisors L.P., (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, 2020, securities noted as such
      amounted to $90,092,503 or 7.1% of net assets.

(g)   This issuer is in default and interest is not being accrued by the Fund
      nor paid by the issuer.

(h)   Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be illiquid by the Advisor.

(i)  Non-income producing security.

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

(k)   This security is fair valued by the Advisor's Pricing Committee in
      accordance with procedures adopted by the Trust's Board of Trustees, and
      in accordance with provisions of the Investment Company Act of 1940, as
      amended. At October 31, 2020, securities noted as such are valued at $0 or
      0.0% of net assets.

(l)   Rate shown reflects yield as of October 31, 2020.

(m)   Aggregate cost for federal income tax purposes is $1,349,340,118. As of
      October 31, 2020, the aggregate gross unrealized appreciation for all
      investments in which there was an excess of value over tax cost was
      $3,640,327 and the aggregate gross unrealized depreciation for all
      investments in which there was an excess of tax cost over value was
      $57,679,390. The net unrealized depreciation was $54,039,063.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the First Trust Senior Loan Fund (the "Fund"), a diversified series of
the Trust, which trades under the ticker "FTSL" on The Nasdaq Stock Market LLC
("Nasdaq"). Unlike conventional mutual funds, the Fund issues and redeems shares
on a continuous basis, at net asset value ("NAV"), only in large specified
blocks consisting of 50,000 shares called a "Creation Unit." Creation Units are
generally issued and redeemed for cash and, in certain circumstances, in-kind
for securities in which the Fund invests. Except when aggregated in Creation
Units, the shares are not redeemable securities of the Fund.

The Fund's primary investment objective is to provide high current income. The
Fund's secondary investment objective is the preservation of capital. Under
normal market conditions, the Fund seeks to outperform each of the S&P/LSTA U.S.
Leveraged Loan 100 Index and the Markit iBoxx USD Liquid Leveraged Loan Index by
investing at least 80% of its net assets (including investment borrowings) in
first lien senior floating rate bank loans ("Senior Loans")(1). The S&P/LSTA
U.S. Leveraged Loan 100 Index (the "Primary Index") is a market value-weighted
index designed to measure the performance of the largest segment of the U.S.
syndicated leveraged loan market. The Primary Index consists of 100 loan
facilities drawn from a larger benchmark, the S&P/LSTA Leveraged Loan Index. The
Markit iBoxx USD Liquid Leveraged Loan Index (the "Secondary Index") selects the
100 most liquid Senior Loans in the market. The Fund does not seek to track
either the Primary or Secondary Index, but rather seeks to outperform each of
the indices. It is anticipated that the Fund, in accordance with its principal
investment strategy, will invest approximately 50% to 75% of its net assets in
Senior Loans that are eligible for inclusion in and meet the liquidity
thresholds of the Primary and/or the Secondary Indices at the time of
investment.

A Senior Loan is an advance or commitment of funds made by one or more banks or
similar financial institutions to one or more corporations, partnerships or
other business entities and typically pays interest at a floating or adjusting
rate that is determined periodically at a designated premium above a base
lending rate, most commonly the London Interbank Offered Rate. The Fund invests
primarily in Senior Loans that are below investment grade quality at the time of
investment. The Fund invests in Senior Loans made predominantly to businesses
operating in North America, but may also invest in Senior Loans made to
businesses operating outside of North America.

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Pricing Committee of the Fund's

      Financial Statements include Senior Loans.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                                OCTOBER 31, 2020

investment advisor, First Trust Advisors L.P. ("First Trust" or the "Advisor"),
in accordance with valuation procedures adopted by the Trust's Board of
Trustees, and in accordance with provisions of the 1940 Act. Investments valued
by the Advisor's Pricing Committee, if any, are footnoted as such in the
footnotes to the Portfolio of Investments. The Fund's investments are valued as
follows:

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

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

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

      Exchange-traded funds 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 principal market for such securities.

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

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

      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 Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) 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


                                                                         Page 23

source; a security with respect to which an event has occurred that is likely to
materially affect the value of the security after the market has closed but
before the calculation of the Fund's NAV or make it difficult or impossible to
obtain a reliable market quotation; and a security whose price, as provided by
the third-party pricing service, does not reflect the security's fair value. As
a general principle, the current fair value of a security would appear to be the
amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

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

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

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

            4)    the financial statements of the borrower/issuer;

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

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

                  (or equity securities) of the borrower/issuer, or comparable
                  companies;

            8)    the coupon payments;

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

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

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

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

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

           14)    other relevant factors.

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of October 31, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                                OCTOBER 31, 2020

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.

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.

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. Due
to the nature of the Senior Loan market, the actual settlement date may not be
certain at the time of the purchase or sale for some of the Senior Loans.
Interest income on such Senior Loans is not accrued until settlement date. 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. The Fund
had no when-issued, delayed-delivery, or forward purchase commitments (other
than unfunded loan commitments discussed below) as of October 31, 2020.

C. UNFUNDED LOAN COMMITMENTS

The Fund may enter into certain credit agreements, all or a portion of which may
be unfunded. The Fund is obligated to fund these loan commitments at the
borrower's discretion. Unfunded loan commitments are marked-to-market daily, and
any unrealized appreciation (depreciation) is included in the Statement of
Assets and Liabilities and Statement of Operations. In connection with these
commitments, the Fund earns a commitment fee typically set as a percentage of
the commitment amount. As of October 31, 2020, the Fund had the following
unfunded loan commitment:

D. 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, 2020, and for the fiscal
year then ended are as follows:

E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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

Distributions from net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying


                                                                         Page 25

                                OCTOBER 31, 2020

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, 2020 and 2019 was as follows:



Distributions paid from:                               2020            2019
Ordinary income.................................  $   53,352,275  $   74,733,494
Capital gains...................................              --              --
Return of capital...............................         984,628         385,786


As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:



Undistributed ordinary income................... $            --
Accumulated capital and other gain (loss).......     (73,961,664)
Net unrealized appreciation (depreciation)......     (54,040,099)


F. 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 2017,
2018, 2019, and 2020 remain open to federal and state audit. As of October 31,
2020, 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. As of October 31, 2020, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $73,961,664.

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, 2020, 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,
2020, the adjustments for the Fund were as follows:



                               ACCUMULATED
            ACCUMULATED        NET REALIZED
           NET INVESTMENT      GAIN (LOSS)
           INCOME (LOSS)      ON INVESTMENTS     PAID-IN CAPITAL
           --------------     --------------     ---------------
           $       37,255     $      811,084     $      (848,339)


G. EXPENSES

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

H. NEW ACCOUNTING PRONOUNCEMENT

On March 30, 2017, the FASB issued Accounting Standards Update ("ASU") 2017-08
"Premium Amortization on Purchased Callable Debt Securities," which amends the
amortization period for certain purchased callable debt securities held at a
premium by shortening such period to the earliest call date. The new guidance
requires an entity to amortize the premium on a callable debt security within
its scope to the earliest call date, unless the guidance for considering
estimated prepayments is applied. If the call option is not exercised at the
earliest call date, the yield is reset to the effective yield using the payment
terms of the security. If the security has more than one call date and the
premium was amortized to a call price greater than the next call price, any
excess of the amortized cost basis over the amount repayable at the next call
date will be amortized to that date. If there are no other call dates, any
excess of the amortized cost basis over the par amount will be amortized to
maturity. Discounts on purchased callable debt securities will continue to be
amortized to the security's maturity date. ASU 2017-08 is effective for public
business entities for fiscal years, and interim periods within those fiscal
years, beginning after December 15, 2018. ASU 2017-08 was adopted for these
financial statements and did not have a material impact.

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 0.85% 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
("BNYM"). Under the service agreements, BNYM performs custodial, fund
accounting, certain administrative services, and transfer agency services for
the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As
fund accountant and administrator, BNYM is responsible for maintaining the books
and records of the Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for the Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.

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,
defined-outcome fund or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and the 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
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

For the fiscal year ended October 31, 2020, the cost of purchases and proceeds
from sales of investments, excluding short-term investments and in-kind
transactions, were $1,074,196,258 and $1,361,178,299, respectively.

For the fiscal year ended October 31, 2020, there were no in-kind transactions.


                                                                         Page 27

                                 5. BORROWINGS

The Trust, on behalf of the Fund, along with First Trust Exchange-Traded Fund
III and First Trust Series Fund have a $410 million Credit Agreement with The
Bank of Nova Scotia ("Scotia") as administrative agent for a group of lenders.
Prior to November 25, 2019, the commitment amount was $385 million. Scotia
charges a commitment fee of 0.25% of the daily amount of the excess of the
commitment amount over the outstanding principal balance of the loans and an
agency fee. First Trust allocates the commitment fee and agency fee amongst the
funds that have access to the credit line. To the extent that the Fund accesses
the credit line, there would also be an interest fee charged. The Fund did not
have any borrowings outstanding during the fiscal year ended October 31, 2020.

                 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Due to the nature of the Fund's investments, the
Fund's Creation Units are generally issued and redeemed for cash, although
Creation Units may be issued in-kind for securities in which the Fund invests in
limited circumstances. Authorized Participants purchasing Creation Units must
pay to BNYM, as transfer agent, a creation transaction fee (the "Creation
Transaction Fee") regardless of the number of Creation Units purchased in the
transaction. The Creation Transaction Fee may increase or decrease with changes
in the Fund's portfolio. The price for each Creation Unit will equal the daily
NAV per share 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 or stamp taxes. When Creation Units are issued for cash,
the Authorized Participant may also be assessed an amount to cover the cost of
purchasing portfolio securities, including 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 such securities.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's
portfolio. When shares are redeemed for cash, the Authorized Participant may
also be assessed an amount to cover other costs, including 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
portfolio securities sold in connection with the redemption.

                              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, 2022.

                               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
were no subsequent events, requiring recognition or disclosure in the financial
statements that have not already been disclosed.

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 Senior Loan Fund (the "Fund"), a series of the First Trust Exchange-Traded
Fund IV, including the portfolio of investments, as of October 31, 2020, 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, 2020, 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, 2020, by correspondence with
the custodian, agent banks and brokers; when replies were not received from
agent banks and brokers, we performed other auditing procedures. We believe that
our audits provide a reasonable basis for our opinion.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                          OCTOBER 31, 2020 (UNAUDITED)

                      PROXY VOTING POLICIES AND PROCEDURES

A description of the policies and procedures that the Trust uses to determine
how to vote proxies and information on how the Fund voted proxies relating to
its portfolio securities during the most recent 12-month period ended June 30 is

                            FEDERAL TAX INFORMATION

Distributions paid to the foreign shareholders during the Fund's fiscal year
ended October 31, 2020 that were properly designated by the Fund as
"interest-related dividends" or "short-term capital gain dividends," may not be

such foreign shareholders.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2020, 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 large
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
not concentrated.

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.

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.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.


                                                                         Page 31

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                               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 Senior Loan Fund (the "Fund"). The
Board approved the continuation of the Agreement for a one-year period ending
June 30, 2021 at a meeting held on June 8, 2020. 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 reasonable
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 May 11, 2020 and June 8, 2020, 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 fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May

                          OCTOBER 31, 2020 (UNAUDITED)

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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Fund since the onset of the
COVID-19 pandemic. 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 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 Leveraged Finance Investment
Team 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 Leveraged
Finance Investment Team and noted the Board's prior meetings with members of the
Team. The Board considered the Advisor's statement that it applies the same
oversight model internally with its Leveraged Finance Investment Team 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 May 11,
2020 meeting, described to the Board the scope of its ongoing investment in
additional infrastructure and personnel 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 advisory 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 May 11, 2020
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, 2019
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 for the one-, three- and
five-year periods ended December 31, 2019. The Board also noted that the Fund
underperformed the benchmark index for the one , three- and five-year periods
ended December 31, 2019.


                                                                         Page 33

                          OCTOBER 31, 2020 (UNAUDITED)

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board considered that the Advisor had
identified as a fall-out 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 fall-out 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.

                                  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 Senior Loan Fund (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, 2019, the amount of remuneration paid (or to
be paid) by First Trust in respect of the Fund is $5,628,611. This figure is
comprised of $714,579 paid (or to be paid) in fixed compensation and $4,914,032
paid (or to be paid) in variable compensation. There were a total of 22
beneficiaries of the remuneration described above. Those amounts include
$365,981 paid (or to be paid) to senior management of First Trust and $5,262,630
paid (or to be paid) to other employees whose professional activities have a
material impact on the risk profiles of First Trust or the Fund (collectively,
"Code Staff").

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.

                          OCTOBER 31, 2020 (UNAUDITED)

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.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, including the Fund, monitors
the funds' holdings of assets classified as illiquid investments to seek to
ensure they do not exceed 15% of a fund's net assets and establishes policies
and procedures regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund, including the Fund, that is required under the Program to have one,
and any material changes to the Program. Note that because the Funds primarily
hold assets that are highly liquid investments, the Funds have not adopted a
highly liquid investment minimum.

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

                        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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

SHAREHOLDER LETTER

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Tactical High Yield ETF (the "Fund"), which contains detailed information about
the Fund for the twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

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

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

FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)

The primary investment objective of the First Trust Tactical High Yield ETF (the
"Fund") is to provide current income. The Fund's secondary investment objective
is to provide capital appreciation. Under normal market conditions, the Fund
invests at least 80% of its net assets (including investment borrowings) in high
yield debt securities that are rated below investment grade at the time of
purchase or unrated securities deemed by the Fund's advisor to be of comparable
quality. Below investment grade securities are those that, at the time of
purchase, are rated lower than "BBB-" by Standard & Poor's Ratings Group, a
division of the McGraw Hill Companies, Inc., or lower than "Baa3" by Moody's
Investors Service, Inc., or comparably rated by another nationally recognized
statistical rating organization. High yield debt securities that are rated below
investment grade are commonly referred to as "junk" debt. Such securities may
include U.S. and non-U.S. corporate debt obligations, bank loans and convertible
bonds. For purposes of determining whether a security is below investment grade,
the lowest available rating will be considered. The Fund may invest no more than
15% in non-income producing securities including Distressed Securities (defined
below) and common stocks. Companies whose financial condition is troubled or
uncertain and that may be involved in bankruptcy proceedings, reorganizations or
financial restructurings are referred to herein as "Distressed Securities." The
Fund may, under normal market conditions, invest up to 40% of its net assets
(including investment borrowings) in bank loans; however the Fund invests no
more than 15% of its net assets (including investment borrowings) in junior
loans, and all other bank loans in which the Fund invests are first lien senior
secured floating rate bank loans. The Fund may invest in listed and
over-the-counter derivatives to the extent permitted by the Nasdaq Stock Market
LLC. The Fund may not be appropriate for all investors.

</TABLE>


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 periods indicated. "Cumulative Annual
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 the shares of
the Fund will vary with changes in market conditions. Shares of the Fund may be
worth more or less than their original cost when they are redeemed or sold in
the market. The Fund's past performance is no guarantee of future performance.

(1)   Percentages are based on the long positions only. Money market funds and
      short positions are excluded.


(2)   The ratings are by Standard & Poor's Rating Group, a division of the
      McGraw-Hill Companies, Inc. 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 except for
      those debt obligations that are only privately rated. Ratings are measured
      on a scale that generally ranges from AAA (highest) to D (lowest).
      Investment grade is defined as those issuers that have a long-term credit

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.

                                   COMMENTARY

The First Trust Tactical High Yield ETF (the "Fund") is an actively managed
exchanged-traded fund ("ETF"). The Fund's primary investment objective is to
provide current income, with a secondary objective of capital appreciation.

MARKET RECAP

As we ended 2019, the Federal Reserve (the "Fed") had cut interest rates for the
last time in October 2019 and in December indicated that no action would be
likely in 2020 given the persistently low inflation environment. In January
2020, the United States and China signed "Phase One" of a trade agreement and
U.S. economic data remained strong. The combination of a patient Fed, improving
U.S.-China trade relations, and a robust domestic economy propelled the S&P
500(R) Index to new highs in late February 2020. Shortly after, as the
coronavirus ("COVID-19") pandemic gripped the world's attention, the financial
market implications from the onset of the resulting global economic shutdown
became clear. Equities experienced their most rapid sell-off since the global
financial crisis in 2008. By March 23, 2020 the S&P 500(R) Index was down nearly
-34% from its all-time high set on February 19, 2020. Policy makers then took
unprecedented steps to stabilize the markets. Central Banks around the world cut
interest rates and governments announced aggressive monetary stimulus packages.
Domestically, the CARES Act was passed and signed into law on March 27. The bill
included a historic $2 trillion stimulus package aimed at sending financial aid
to struggling U.S. citizens and businesses affected by COVID-19. The Fed also
cut the target Fed Funds rate by 150 basis points ("bps") during the month of
March. As fears subsided, and optimism that the combination of a re-opening of
the U.S. economy and aggressive fiscal and monetary stimulus would result in a
quicker than expected recovery, markets surpassed pre-pandemic levels before a
resurgence in COVID-19 infections tempered investor optimism at the end of the
12-month period ended October 31, 2020.

High-Yield Bond Market

High-yield bond spreads over U.S. Treasuries increased 119 bps to end the
12-month period ended October 31, 2020 at T+534 bps, which is well below the
spread of T+1087 bps experienced on March 23, 2020 during the depths of the
pandemic-induced market selloff. The spread is slightly inside the long-term
average spread over U.S. Treasuries of T+566 bps (December 1997 - October 2020).
High-yield bond funds experienced robust inflows in the period as the Fed added
high-yield bonds to its list of eligible asset classes for purchase under its
Secondary Market Corporate Credit Facility. This combined with investor appetite
for yield drove strong demand.

Higher quality high-yield bonds (BB rated) outperformed lower quality high-yield
bonds (B rated or below) in the period, which was a continuation of the trend
from the prior year period. High-yield bond issues rated BB returned 4.60%,
outperforming the 0.77% return of B rated issues and outperforming the -2.73%
return of issues rated CCC in the period. The average price of high-yield bonds
in the market at the beginning of the period was $99.09. The price dropped to
$78.60 on March 23, 2020 and subsequently recovered to end the period with an
average price of $99.29.

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

Senior Loan Market

Senior loan spreads over 3-month London Interbank Offered Rate ("LIBOR")
increased 70 bps during the 12-month period ended October 31, 2020 to L+585 bps.
This is above the long-term average spread of L+518 (December 1997 - October
2020). Retail senior loan funds have experienced 25 consecutive monthly outflows
with demand impacted by the dramatic decrease of the 3-month LIBOR rate during
the same period.

Single-B rated senior loans outperformed both higher and lower quality senior
loans during the period, returning 3.13% while BB rated issues returned -0.60%.
Single Bs also outperformed CCC rated issues which returned -1.41% during the
same period. The average price of senior loans in the market decreased from
$95.42 in the beginning of the period to $93.17 at the end of the period.

Default Rates

During the 12-month period ended October 31, 2020, default rates increased
within the ICE BofA US High Yield Constrained Index and the S&P/LSTA Leveraged
Loan Index. The last twelve months ("LTM") default rate within the high-yield
bond market ended the period at 6.34% compared to the 2.54% default rate at the
beginning of the period. The senior loan market default rate ended the period at
4.11% compared to the 1.43% rate at the beginning of the period. The default
rates in both the high-yield bond market and the senior loan market are above
the long-term average default rates of 3.17% and 2.90%, respectively. Looking
forward, we anticipate high yield and senior loan market default rates to remain
above the long-term averages through 2021, but anticipate a decline in the
default rate as the economy recovers and the introduction of a vaccine bring a
recovery to the industries most impacted by COVID-19.

FUND PERFORMANCE

The Fund returned 2.92% on a net asset value ("NAV") basis and 3.18% on a market
price basis over the LTM period ended October 31, 2020. The ICE BofA US High
Yield Constrained Index ("the Index") returned 2.44% over the same time period.

The Fund held 410 individual positions diversified across 49 industries at the
end of the reporting period. Health Care Providers & Services (15.50%), Media
(12.95%), and Software (12.69%) were the Fund's largest three industry exposures
at the end of the period. By comparison, the Fund held 277 individual position
across 40 industries as of October 31, 2019. The Fund's duration as of October
31, 2020 was 2.59 years. The Fund strategically deployed leverage over the LTM
period, which was a tailwind to performance as risk asset prices generated
positive returns during the period. The Fund's long position was 116.56% as of
October 31, 2020.

During the LTM period the Fund's performance significantly benefitted from its
de minimis position in the energy industry. Energy was the worst performing
industry in the Index during the period. The average weight of the energy
industry in the Index during the LTM period was 12.28%, while the Fund held a
modest 0.64% allocation. The significant underweight during a period of
declining energy prices was significantly accretive to relative returns. In
addition, the Fund benefited from its overweight position and asset selection in
the healthcare industry and an overweight exposure to the technology &
electronics industry. Within the healthcare industry the Fund's overweight
position in a healthcare cost management solutions company, a managed services
provider, and a drug manufacturer all outperformed the broader healthcare
industry. The healthcare industry is expected to benefit from a divided
government, which we believe will result in no major healthcare legislation or
significant changes to the regulatory environment. Moreover, we anticipate a
continued recovery in healthcare volumes as the economy recovers from COVID-19.
Finally, the technology & electronics industry was the third-best performing
industry in the Index during the LTM period and an overweight position
benefitted the Fund. The average weight to the industry in the Index during the
LTM period was 4.98%, while the Fund had a 14.59% allocation.

Modestly offsetting these contributors were the Fund's overweight position and
asset selection within the leisure industry and underweight position and asset
selection within the basic industry and the automotive industry. The primary
driver of the leisure industry underperformance was the Fund's overweight
exposure to movie theaters. Movie theaters continue to face headwinds as new
movie releases have been pushed further out on the calendar as the industry
awaits a COVID-19 vaccine.

The Fund's most recent monthly distribution of $0.204 per share is $0.009 per
share higher than the monthly distribution paid in October 2019. At the end of
the period, the effective yield based on the distributions for the trailing
twelve months was 5.09% based on NAV and 5.07% based on market price.

                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

The Fund experienced two defaults during the LTM period compared to 54 defaults
within the JP Morgan High-Yield Bond Universe during the LTM period. Since
inception, the Fund has experienced nine defaults, which compares to 237 within
the JP Morgan High-Yield Bond Universe during the same period. The Fund's LTM
default rate was 1.93% at month-end. The JP Morgan High-Yield Bond Universe
default rate was 6.34%.

MARKET AND FUND OUTLOOK

We believe high yield bonds are supported by spreads that remain in line with
the long-term average, opportunistic pockets of value across ratings and
industries, a low interest rate environment and an improving U.S. economy.
Moreover, while the default rate has increased during the period, we believe
individual credits that came into the 2020 recession with too much leverage and
sectors most impacted by COVID-19 will face a higher likelihood of defaults
including, but not limited to Energy, Travel, Leisure and Retail, in no
particular order. However, generally, businesses that haven't been impacted by
COVID-19 continue to perform well, in our opinion.

We remain confident that improving economic conditions, unprecedented support
from the Fed, and the potential for additional stimulus will provide a backdrop
for continued recovery in high-yield bonds, in our view. As we evaluate new
investment opportunities, decisions will continue to be rooted in our rigorous
bottom-up credit analysis and our focus will remain on identifying the
opportunities that we believe offer the best risk and reward balance.

FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (UNAUDITED)

As a shareholder of First Trust Tactical High Yield 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, 2020.

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)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A under the Securities
      Act of 1933, as amended, and may be resold in transactions exempt from
      registration, normally to qualified institutional buyers. Pursuant to
      procedures adopted by the Trust's Board of Trustees, this security has
      been determined to be liquid by First Trust Advisors L.P. ("First Trust"
      or 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, 2020, securities noted as such
      amounted to $1,369,200,245 or 69.4% of net assets.

FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)

PORTFOLIO OF INVESTMENTS (CONTINUED)
OCTOBER 31, 2020

(b)   This security or a portion of this security is segregated as collateral
      for investments sold short.

(c)   This issuer is in default and interest is not being accrued by the Fund
      nor paid by the issuer.


(d)   This issuer has filed for protection in bankruptcy court.

(e)   Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be illiquid by the Advisor.

(f)   Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund
      invests generally pay interest at rates which are periodically
      predetermined by reference to a base lending rate plus a premium. These
      base lending rates are generally (i) the lending rate offered by one or
      more major European banks, such as the LIBOR, (ii) the prime rate offered
      by one or more United States banks or (iii) the certificate of deposit
      rate. Certain Senior Loans are subject to a LIBOR floor that establishes a
      minimum LIBOR rate. When a range of rates is disclosed, the Fund holds
      more than one contract within the same tranche with identical LIBOR
      period, spread and floor, but different LIBOR reset dates.

(g)   Senior Loans generally are subject to mandatory and/or optional
      prepayment. As a result, the actual remaining maturity of Senior Loans may
      be substantially less than the stated maturities shown.

(h)   The issuer may pay interest on the loans (1) entirely in cash or (2) in
      the event that both the Payme("PIK") Toggle Condition has been satisfied
      and the issuer elects to exercise the PIK interest, 2.50% payable in cash
      and 7.00% payable as PIK interest. The First interest payment is scheduled
      for January 4, 2021.

(i)   On October 1, 2020, Akorn Holding Company LLC completed a Bankruptcy Plan
      of Reorganization. In connection with the Plan of Reorganization, the Fund
      received a portion of a new exit term loan and a share of the newly issued
      common equity shares in the re-organized company.

(j)   Non-income producing security.

(k)   Rate shown reflects yield as of October 31, 2020.

(l)   Aggregate cost for federal income tax purposes is $1,959,252,935. As of
      October 31, 2020, the aggregate gross unrealized appreciation for all
      investments in which there was an excess of value over tax cost was
      $45,945,157 and the aggregate gross unrealized depreciation for all
      investments in which there was an excess of tax cost over value was
      $46,600,585. The net unrealized depreciation was $655,428. The amounts
      presented are inclusive of investments sold short.

(m)   Zero coupon security.

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the First Trust Tactical High Yield ETF (the "Fund"), a diversified
series of the Trust which trades under the ticker "HYLS" on The Nasdaq Stock
Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and
redeems shares on a continuous basis, at net asset value ("NAV"), only in large
specified blocks consisting of 50,000 shares called a "Creation Unit." Creation
Units are generally issued and redeemed for cash and, in certain circumstances,
in-kind for securities in which the Fund invests. Except when aggregated in
Creation Units, the Fund's shares are not redeemable securities.

The primary investment objective of the Fund is to provide current income. The
Fund's secondary investment objective is to provide capital appreciation. Under
normal market conditions, the Fund invests at least 80% of its net assets
(including investment borrowings) in high yield debt securities that are rated
below investment grade at the time of purchase or unrated securities deemed by
the Fund's advisor to be of comparable quality. Below investment grade
securities are those that, at the time of purchase, are rated lower than "BBB-"
by Standard & Poor's Ratings Group, a division of the McGraw Hill Companies,
Inc., or lower than "Baa3" by Moody's Investors Service, Inc., or comparably
rated by another nationally recognized statistical rating organization. High
yield debt securities that are rated below investment grade are commonly
referred to as "junk" debt. Such securities may include U.S. and non-U.S.
corporate debt obligations, bank loans and convertible bonds. For purposes of
determining whether a security is below investment grade, the lowest available
rating will be considered.

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

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

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

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

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                                OCTOBER 31, 2020

      Shares of open-end funds are valued at fair value which is based on NAV
      per share.

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

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

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

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

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

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

            4)    the financial statements of the borrower/issuer;

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

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

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

            8)    the coupon payments;

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

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

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

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                                OCTOBER 31, 2020

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

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

           14)    other relevant factors.

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of October 31, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

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.

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.

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. Due
to the nature of the Senior Loan market, the actual settlement date may not be
certain at the time of the purchase or sale for some of the Senior Loans.
Interest income on such Senior Loans is not accrued until settlement date. The
Fund maintains liquid assets with current value at least equal to the amount of
its when-issued, delayed-delivery or forward purchase commitments. The Fund had
no when-issued, delayed-delivery, or forward purchase commitments (other than
unfunded loan commitments discussed below) as of October 31, 2020.

C. SHORT SALES

Short sales are utilized for investment and risk management purposes 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

                                OCTOBER 31, 2020

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.

The Fund has established an account with Pershing, LLC for the purpose of
purchasing or borrowing securities on margin. The Fund pays interest on any
margin balance, which is calculated as the daily margin account balance times
the broker's margin interest rate. At October 31, 2020, the Fund had $62,579,860
in restricted cash associated with investments sold short and $344,970,189 of
investments sold short as shown on Statement of Assets and Liabilities. The Fund
is charged interest on debit margin balance at a rate equal to the Overnight
Bank Funding Rate plus 75 basis points. With regard to securities held short,
the Fund is credited a rebate equal to the market value of its short positions
at a rate equal to the Overnight Bank Funding Rate less 35 basis points. This
rebate rate applies to easy to borrow securities. Securities that are hard to
borrow may earn a rebate that is less than the foregoing or may be subject to a
premium charge on a security by security basis. The different rebate rate is
determined at the time of a short sale request. At October 31, 2020, the Fund
had a debit margin balance of $282,384,540 with an interest rate of 0.83%. For
the fiscal year ended October 31, 2020, the Fund had margin interest expense of
$775,201, as shown on the Statement of Operations. For the fiscal year ended
October 31, 2020, the average margin balance and interest rates were $82,303,401
and 1.36%, respectively.

D. RESTRICTED CASH

Restricted cash includes cash on deposit with other banks or brokers that is
legally restricted as to the withdrawal and primarily serves as collateral for
investments sold short. The Fund presents restricted cash activity within
"Increase in cash and restricted cash" and as part of "Cash and restricted cash
at beginning of period" and "Cash and restricted cash at end of period" in the
Statement of Cash Flows, along with a reconciliation of those balances in the
Statement of Assets and Liabilities.

E. UNFUNDED LOAN COMMITMENTS

The Fund may enter into certain credit agreements, all or a portion of which may
be unfunded. The Fund is obligated to fund these loan commitments at the
borrower's discretion. Unfunded loan commitments are marked-to-market daily, and
any unrealized appreciation (depreciation) is included in the Statement of
Assets and Liabilities and Statement of Operations. In connection with these
commitments, the Fund earns a commitment fee typically set as a percentage of
the commitment amount. As of October 31, 2020, the Fund had the following
unfunded loan commitment:

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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

Distributions from net investment income and realized capital gains are
determined in accordance with federal income tax regulations, which may differ
from U.S. GAAP. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These permanent differences are primarily due to the varying
treatment of income and gain/loss on significantly modified 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.


                                                                         Page 33

                                OCTOBER 31, 2020

The tax character of distributions paid during the fiscal years ended October
31, 2020 and 2019 was as follows:

Distributions paid from:                               2020            2019
Ordinary income.................................  $   84,896,005  $   66,781,356
Capital gains...................................              --              --
Return of capital...............................              --         495,649


As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:



Undistributed ordinary income...................  $    1,007,704
Accumulated capital and other gain (loss).......     (52,774,075)
Net unrealized appreciation (depreciation)......        (657,242)


G. 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 2017,
2018, 2019, and 2020 remain open to federal and state audit. As of October 31,
2020, 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. As of October 31, 2020, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $52,774,075.

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, 2020, 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,
2020, the adjustments for the Fund were as follows:



                                  ACCUMULATED
               ACCUMULATED        NET REALIZED
              NET INVESTMENT      GAIN (LOSS)
              INCOME (LOSS)      ON INVESTMENTS     PAID-IN CAPITAL
              --------------     --------------     ---------------
              $    3,434,868     $   (2,723,295)    $      (711,573)


H. EXPENSES

Expenses, other than the investment advisory fee and other excluded expenses,
are paid by the Advisor (see Note 3). The Fund is subject to an interest expense
due to the costs associated with the Fund's short positions in securities.

I. NEW ACCOUNTING PRONOUNCEMENTS

On March 30, 2017, the FASB issued Accounting Standards Update ("ASU") 2017-08
"Premium Amortization on Purchased Callable Debt Securities," which amends the
amortization period for certain purchased callable debt securities held at a
premium by shortening such period to the earliest call date. The new guidance
requires an entity to amortize the premium on a callable debt security within
its scope to the earliest call date, unless the guidance for considering
estimated prepayments is applied. If the call option is not exercised at the
earliest call date, the yield is reset to the effective yield using the payment

terms of the security. If the security has more than one call date and the
premium was amortized to a call price greater than the next call price, any
excess of the amortized cost basis over the amount repayable at the next call
date will be amortized to that date. If there are no other call dates, any
excess of the amortized cost basis over the par amount will be amortized to
maturity. Discounts on purchased callable debt securities will continue to be
amortized to the security's maturity date. ASU 2017-08 is effective for public
business entities for fiscal years, and interim periods within those fiscal
years, beginning after December 15, 2018. ASU 2017-08 was adopted for these
financial statements and did not have a material impact.

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, brokerage
commissions and other expenses connected with the execution of portfolio
transactions, expenses associated with short sale 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 0.95% of its average daily net assets.

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

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,
defined-outcome fund or is an index fund.

Additionally, the Lead Independent Trustee and the Chairmen 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
Chairmen rotate every three years. The officers and "Interested" Trustee receive
no compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

For the fiscal year ended October 31, 2020, the cost of purchases and proceeds
from sales of investments, excluding short-term investments, investments sold
short and in-kind transactions, were $2,047,460,237 and $1,157,659,965,
respectively. The cost of purchases to cover short sales and the proceeds of
short sales were $22,087,500 and $19,768,750, respectively.

For the fiscal year ended October 31, 2020, there were no in-kind transactions.

                                 5. BORROWINGS

The Trust, on behalf of the Fund, along with the First Trust Series Fund and
First Trust Variable Insurance Trust, entered into a $200 million Credit
Agreement ("Line of Credit") with BNYM, to be a liquidity backstop during
periods of high redemption volume. A commitment fee of 0.15% of the daily amount
of the excess of the commitment amount over the outstanding principal balance of
the loans will be charged by BNYM, which First Trust allocates amongst the funds
that had access to the Line of Credit. To the extent that the Fund accesses the
Line of Credit, there would also be an interest fee charged. The Fund did not
have any borrowings outstanding during the fiscal year ended October 31, 2020.


                                                                         Page 35

                                OCTOBER 31, 2020

                 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Due to the nature of the Fund's investments, the
Fund's Creation Units are generally issued and redeemed for cash, although
Creation Units may be issued in-kind for securities in which the Fund invests in
limited circumstances. Authorized Participants purchasing Creation Units must
pay to BNYM, as transfer agent, a creation transaction fee (the "Creation
Transaction Fee") regardless of the number of Creation Units purchased in the
transaction. The Creation Transaction Fee may increase or decrease with changes
in the Fund's portfolio. The price for each Creation Unit will equal the daily
NAV per share 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 or stamp taxes. When Creation Units are issued for cash,
the Authorized Participant may also be assessed an amount to cover the cost of
purchasing portfolio securities, including 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 such securities. Authorized
Participants redeeming Creation Units must pay to BNYM, as transfer agent, a
standard redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's
portfolio. When shares are redeemed for cash, the Authorized Participant may
also be assessed an amount to cover other costs, including 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
portfolio securities sold in connection with the redemption.

                              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, 2022.

                               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
were no subsequent events requiring recognition or disclosure in the financial
statements that have not already been disclosed.

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 Tactical High Yield ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2020, the related statement of operations and cash flows 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, 2020, and the results of
its operations and its cash flows 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, 2020, by correspondence with
the custodian, agent banks and brokers; when replies were not received from
agent banks and brokers, we performed other auditing procedures. We believe that
our audits provide a reasonable basis for our opinion.

                          OCTOBER 31, 2020 (UNAUDITED)

                      PROXY VOTING POLICIES AND PROCEDURES

A description of the policies and procedures that the Trust uses to determine
how to vote proxies and information on how the Fund voted proxies relating to
its portfolio securities during the most recent 12-month period ended June 30 is
available (1) without charge, upon request, by calling (800) 988-5891; (2) on
the Fund's website at www.ftportfolios.com; and (3) on the Securities and
Exchange Commission's ("SEC") website at www.sec.gov.

                               PORTFOLIO HOLDINGS

The Fund files portfolio holdings information for each month in a fiscal quarter
within 60 days after the end of the relevant fiscal quarter on Form N-PORT.
Portfolio holdings information for the third month of each fiscal quarter will
be publicly available on the SEC's website at www.sec.gov. The Fund's complete
schedule of portfolio holdings for the second and fourth quarters of each fiscal
year is included in the semi-annual and annual reports to shareholders,
respectively, and is filed with the SEC on Form N-CSR. The semi-annual and
annual report for the Fund is available to investors within 60 days after the
period to which it relates. The Fund's Forms N-PORT and Forms N-CSR are
available on the SEC's website listed above.

                            FEDERAL TAX INFORMATION

Distributions paid to the foreign shareholders during the Fund's fiscal year
ended October 31, 2020 that were properly designated by the Fund as
"interest-related dividends" or "short-term capital gain dividends," may not be
subject to federal income tax provided that the income was earned directly by
such foreign shareholders.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2020, 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 large
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
not concentrated.

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.

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.

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.


                                                                         Page 39

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

          NOT FDIC INSURED    NOT BANK GUARANTEED    MAY LOSE VALUE

                               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 Tactical High Yield ETF (the
"Fund"). The Board approved the continuation of the Agreement for a one-year
period ending June 30, 2021 at a meeting held on June 8, 2020. 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
reasonable 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 May 11, 2020 and June 8, 2020, 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 fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May
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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Fund since the onset of the
COVID-19 pandemic. The Board applied its business judgment to determine whether

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                          OCTOBER 31, 2020 (UNAUDITED)

the arrangement between the Trust and the Advisor continues to be a reasonable
business arrangement from 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 Leveraged Finance Investment
Team 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 Leveraged
Finance Investment Team and noted the Board's prior meetings with members of the
Team. The Board considered the Advisor's statement that it applies the same
oversight model internally with its Leveraged Finance Investment Team 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
objective, 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 May 11,
2020 meeting, described to the Board the scope of its ongoing investment in
additional infrastructure and personnel 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 objective, 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 advisory or unitary 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
May 11, 2020 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, 2019
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 for the one-, three- and
five-year periods ended December 31, 2019 but underperformed the benchmark index
for the one-, three- and five-year periods ended December 31, 2019.

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the management of the Fund would benefit the Advisor, but that


                                                                         Page 41

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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board considered that the Advisor had
identified as a fall-out 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 fall-out 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.

                                  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 Tactical High Yield 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, 2019, the amount of remuneration paid (or to
be paid) by First Trust in respect of the Fund is $4,451,157. This figure is
comprised of $565,095 paid (or to be paid) in fixed compensation and $3,886,062
paid (or to be paid) in variable compensation. There were a total of 22
beneficiaries of the remuneration described above. Those amounts include
$289,421 paid (or to be paid) to senior management of First Trust and $4,161,736
paid (or to be paid) to other employees whose professional activities have a
material impact on the risk profiles of First Trust or the Fund (collectively,
"Code Staff").

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.

                          OCTOBER 31, 2020 (UNAUDITED)

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind. At the May 11, 2020 meeting of the Board of
Trustees, as required by Rule 22e-4 and the Program, the Advisor provided the
Board with a written report prepared by the Advisor that addressed the operation
of the Program during the period from June 1, 2019 (the initial compliance date
for certain requirements of Rule 22e-4) through the Liquidity Committee's annual
meeting held on March 20, 2020 and assessed the Program's adequacy and
effectiveness of implementation during this period, including the operation of
the highly liquid investment minimum for each fund that is required under the
Program to have one, and any material changes to the Program. Note that because
the Fund primarily holds assets that are highly liquid investments, the Fund has
not adopted a highly liquid investment minimum.

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


                                                                         Page 43

                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS


This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
the series of First Trust Exchange-Traded Fund IV (the "Trust") described in
this report (First Trust Enhanced Short Maturity ETF; hereinafter referred to as
the "Fund") to be materially different from any future results, performance or
achievements expressed or implied by the forward-looking statements. When
evaluating the information included in this report, you are cautioned not to
place undue reliance on these forward-looking statements, which reflect the
judgment of the Advisor and its representatives only as of the date hereof. We
undertake no obligation to publicly revise or update these forward-looking
statements to reflect events and circumstances that arise after the date hereof.

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objective. 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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment in
the Fund. It includes details about the Fund and presents data and analysis that
provide insight into the Fund's performance and investment approach.

By reading the portfolio commentary from the portfolio management team of the
Fund, you may obtain an understanding of how the market environment affected the
Fund's performance. The statistical information that follows may help you

Advisor are just that: informed opinions. They should not be considered to be
promises or advice. The opinions, like the statistics, cover the period through
the date on the cover of this report. The material risks of investing in the
Fund are spelled out in the prospectus, the statement of additional information,
and other Fund regulatory filings.

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

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Enhanced Short Maturity ETF (the "Fund"), which contains detailed information
about the Fund for the twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

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

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

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

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

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

</TABLE>


Total returns for the period since inception are calculated from the inception
date of the Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the period indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the period
indicated.

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

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

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.

The Fund is an actively-managed exchange-traded fund ("ETF"). Its investment
objective is to seek current income, consistent with preservation of capital and
daily liquidity.

MARKET RECAP

The front-end of the U.S. bond market improved over the 12 month-period ended
October 31, 2020. The ICE BofA 0-1 Year U.S. Treasury Index and ICE BofA 0-1
Year U.S. Corporate Index, two broad measures of market performance, had returns
of 1.37% and 1.99%, respectively, for the period. However, those returns were
earned through turbulence the market and economy had not witnessed since the
2008-2009 Global Financial Crisis ("GFC").

Solid estimates for 2020 growth abounded to start the year, only to be abruptly
undone in March 2020 as the outbreak of the coronavirus ("COVID-19") upended
markets and whole economies. Investor sentiment eroded sharply, and markets
turned extraordinarily volatile. Industry-wide demand for cash led to forced
selling, subsequently causing severe illiquidity in all markets, including in
Treasuries and agency mortgage-backed securities. By mid-March, spreads on all
credit sectors had quickly gapped out to levels not seen since the GFC. A
potential liquidity crisis in U.S. credit markets was headed off by the U.S.
Federal Reserve (the "Fed"), which slashed interest rates and unleashed an array
of programs designed to ensure the flow of credit in the private and public
sectors. Meanwhile, Congress enacted a fiscal stimulus bill valued at $2
trillion, a sum equal to nearly 10% of the U.S. gross domestic product ("GDP"),
in an effort to support businesses, employees, and households. Collectively,
these measures proved to be a game-changer for the market and the result was a
rapid improvement in sentiment and asset prices.

Over the subsequent months of the reporting period, credit spreads in front-end
bond markets improved and returned to levels seen in January-February 2020.
During this time, issuance of new bonds increased to record levels as many
high-quality companies issued long-term debt to weather the uncertain outlook.
New issuance was easily absorbed as investors sought higher yields amid falling
interest rates and low yields on U.S. Treasury bonds. In aggregate, high-grade
bond funds and ETFs reported inflows for every week between the beginning of
April through the end of October.

Having re-established the Zero Interest Rate Policy regime in the wake of the
pandemic, the Fed also adopted a new, flexible average-inflation-targeting
framework during the third quarter of 2020. We expect this to result in policy
rates remaining at low levels for another two or three years. The Fed's policy
announcement came as the U.S. economy is rebounding from the sharp pullback
experienced in the first half of 2020. While the labor market has yet to fully
heal, employment has continued to bounce back. Non-farm payrolls recouped 12
million jobs from April through October and retail sales were also robust,
doubtlessly aided by economic stimulus measures. As the reporting period came to
a close, it was reported U.S. economic growth jumped to an annualized rate of
33.1% in the third quarter, up from -31.4% in the second quarter and -5.0% in
the first quarter.

PERFORMANCE ANALYSIS

The Fund's net asset value ("NAV") and market performance for the 12-month
period ended October 31, 2020 was 1.34%, versus the ICE BofA 0-1 Year U.S.
Treasury Index's (the "Benchmark") return of 1.37%. The distribution declared on
October 29, 2020 of $0.035 represented an annualized distribution rate of 0.70%
based on the Fund's closing market price of $60.04 on October 30, 2020. The
Fund's distribution rate is not constant and is subject to change over time
based on market conditions and performance of the Fund.

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

The allocation to securitized debt was a source of outperformance with the best
results coming from Agency collateralized mortgage-backed obligations ("CMOs"),
Agency commercial mortgage-backed securities ("CMBS"), and Auto asset-backed
securities ("ABS"). The Fund's relatively small allocation to Treasury
securities was another contributor to outperformance versus the Benchmark. On
the other hand, cash equivalents and corporate bonds moderately underperformed
on a relative basis. Within corporates, the leading detractor was investments in
the Energy sector. Holdings in ten other corporate sectors positively
contributed to relative performance including finance companies, electric
utilities, consumer non-cyclicals, and banking. From a rating quality
perspective, "A" rated corporate bonds delivered slightly better returns
compared to "BBB" rated corporate bonds.

Throughout the 12-month period ended October 31, 2020, the Fund maintained a
diversified allocation with an emphasis on securities having a high level of
liquidity. Overall credit risk was kept low as the investment strategy focused
on high quality, short-term holdings. The Fund's weighted average maturity was
kept around one year and weighted average effective duration between 0.3 and 0.6
years.

MARKET AND FUND OUTLOOK

Despite uncertainty surrounding COVID-19, our outlook for the front-end fixed
income markets and economy is generally positive. We anticipate drug companies
will successfully produce vaccines and therapies for COVID-19 in the near term
and that those will serve as catalysts for a return to more normal social
behavior and more rapid economic growth. From a policy perspective, we expect
lawmakers to provide another round of fiscal stimulus to support households and
small businesses. We also believe the Fed will continue to anchor the front-end
of the Treasury yield curve and short-term funding rates by keeping the Fed
Funds rate at zero.

As a result, our outlook is the economy will continue to recover and that has
supportive implications for credit fundamentals. We are also encouraged by the
strong technical backdrop seen in the front-end given steady flows into funds
and ETFs.

From a strategy perspective, as we head into the closing months of 2020, we
believe credit spreads reflect a great deal of this positive outlook and, as
such, we are cautious about increasing risk exposures significantly. Because our
outlook is for anchored front-end rates, we do not believe yield curve
positioning will have a material impact on performance. Credit spreads are a
different matter and we await opportunities to initiate positions at more
attractive levels. In the corporate space, we remain focused on lending to
leading companies with relatively noncyclical revenues, robust free cash flow,
durable balance sheets, multiple degrees of freedom, and prudent management. We
believe high quality mortgage-backed and asset-backed securities represent some
of the best opportunities in the front-end at this time, given falling
unemployment and our expectation that fiscal stimulus measures will continue
supporting household balance sheets. As always, capital preservation remains a
focus and we expect to maintain a laddered maturity profile of commercial paper
to support liquidity and stable NAV, although low yields in the very front end
of the curve remain a challenge.

As we evaluate new investment opportunities, our research will seek to identify
opportunities that we believe offer the best risk/reward balance, and decisions
will continue to be based on the analysis of data that results in sound,
evidence-based conclusions.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (UNAUDITED)

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended October 31, 2020.

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.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

PORTFOLIO OF INVESTMENTS (CONTINUED)
OCTOBER 31, 2020

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

(a)   Floating or variable rate security.

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended, and may be resold in transactions exempt from
      registration, normally to qualified institutional buyers. Pursuant to
      procedures adopted by the Trust's Board of Trustees, this security has
      been determined to be liquid by First Trust Advisors L.P., the Fund's
      Advisor. 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, 2020, securities noted as such
      amounted to $1,203,382,656 or 23.3% of net assets.

(c)   Fixed-to-floating security. The interest rate shown reflects the fixed
      rate in effect at October 31, 2020. At a predetermined date, the fixed
      rate will change to a floating rate.

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

(e)   Zero coupon security.

(f)   Aggregate cost for federal income tax purposes is $5,182,699,520. As of
      October 31, 2020, the aggregate gross unrealized appreciation for all
      investments in which there was an excess of value over tax cost was
      $16,236,399 and the aggregate gross unrealized depreciation for all
      investments in which there was an excess of tax cost over value was
      $1,147,708. The net unrealized appreciation was $15,088,691. The amounts
      presented are inclusive of derivative contracts.

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the First Trust Enhanced Short Maturity ETF (the "Fund"), a diversified
series of the Trust, which trades under the ticker "FTSM" on The Nasdaq Stock
Market LLC ("Nasdaq"). Unlike conventional mutual funds, the Fund issues and
redeems shares on a continuous basis, at net asset value ("NAV"), only in large
specified blocks consisting of 50,000 shares called a "Creation Unit." Creation
Units are generally issued and redeemed for cash and, in certain circumstances,
in-kind for securities in which the Fund invests, and only to and from
broker-dealers and large institutional investors that have entered into
participation agreements. Except when aggregated in Creation Units, the Fund's
shares are not redeemable securities.

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

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

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

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

            1)    benchmark yields;
            2)    reported trades;

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                OCTOBER 31, 2020

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

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

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

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

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

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

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

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

            4)    the financial statements of the borrower/issuer;

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

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

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

            8)    the coupon payments;

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

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

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

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

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

           14)    other relevant factors.

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

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


                                                                         Page 33

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                OCTOBER 31, 2020

      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, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

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.

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

C. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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

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

The tax character of distributions paid during the fiscal years ended October
31, 2020 and 2019 was as follows:



Distributions paid from:                              2020             2019
Ordinary income................................  $   77,424,693   $   96,211,136
Capital gains..................................              --               --
Return of capital..............................              --               --

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                OCTOBER 31, 2020

As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income..................  $       (2,577)
Accumulated capital and other gain (loss)......     (16,485,857)
Net unrealized appreciation (depreciation).....      15,088,691


D. 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 2017,
2018, 2019, and 2020 remain open to federal and state audit. As of October 31,
2020, 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, 2020, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $16,485,857.

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, 2020, 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. For the fiscal year ended October 31, 2020,
there were no tax adjustments made to accumulated distributable earnings (loss)
accounts due to differences between book and tax treatments.

E. EXPENSES

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

F. NEW ACCOUNTING PRONOUNCEMENT

On March 30, 2017, the FASB issued Accounting Standards Update ("ASU") 2017-08
"Premium Amortization on Purchased Callable Debt Securities", which amends the
amortization period for certain purchased callable debt securities held at a
premium by shortening such period to the earliest call date. The new guidance
requires an entity to amortize the premium on a callable debt security within
its scope to the earliest call date, unless the guidance for considering
estimated prepayments is applied. If the call option is not exercised at the
earliest call date, the yield is reset to the effective yield using the payment
terms of the security. If the security has more than one call date and the
premium was amortized to a call price greater than the next call price, any
excess of the amortized cost basis over the amount repayable at the next call
date will be amortized to that date. If there are no other call dates, any
excess of the amortized cost basis over the par amount will be amortized to
maturity. Discounts on purchased callable debt securities will continue to be
amortized to the security's maturity date. The ASU 2017-08 is effective for
public business entities for fiscal years, and interim periods within those
fiscal years, beginning after December 15, 2018. ASU 2017-08 was adopted for
these financial statements and did not have a material impact.

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.

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                                OCTOBER 31, 2020

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

The Fund has agreed to pay First Trust an annual unitary management fee equal to
0.45% of its average daily net assets. Pursuant to two separate contractual
agreements, First Trust has agreed to waive management fees of 0.05% and 0.15%
of average daily net assets until March 1, 2022. The waiver agreement may be
terminated by action of the Trust's Board of Trustees at any time upon 60 days'
written notice by the Trust on behalf of the Fund or by the Fund's investment
advisor only after March 1, 2022. Pursuant to a contractual agreement between
the Trust, on behalf of the Fund, and First Trust, the management fees paid to
First Trust will be reduced by the portion of the management fees earned by
First Trust from the Fund for assets invested in other investment companies
advised by First Trust. This contractual agreement shall continue until the
earlier of (i) its termination at the direction of the Trust's Board of Trustees
or (ii) upon termination of the Fund's management agreement with First Trust;
however, it is expected to remain in place at least until March 1, 2021. First
Trust does not have the right to recover the fees waived that are attributable
to the assets invested in other investment companies advised by First Trust.
During the fiscal year ended October 31, 2020, the Advisor waived fees of
$3,485,866.

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

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

Additionally, the Lead Independent Trustee and the Chairmen 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
Chairmen will rotate every three years. The officers and "Interested" Trustee
receive no compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The costs of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the fiscal year ended October
31, 2020, were $390,493,452 and $2,327,771,552, respectively. The proceeds from
sales and paydowns of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the fiscal year ended October
31, 2020, were $423,467,474 and $1,987,028,246, respectively.

For the fiscal year ended October 31, 2020, the Fund had no in-kind
transactions.

                 5. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Due to the nature of the Fund's investments, the
Fund's Creation Units are generally issued and redeemed for cash, although
Creation Units may be issued in-kind for securities in which the Fund invests in
limited circumstances. Authorized Participants purchasing Creation Units must
pay to BNYM, as transfer agent, a creation transaction fee (the "Creation
Transaction Fee") regardless of the number of Creation Units purchased in the
transaction. The Creation Transaction Fee may increase or decrease with changes
in the Fund's portfolio. The price for each Creation Unit will equal the daily
NAV per share 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 or stamp taxes. When Creation Units are issued for cash,
the Authorized Participant may also be assessed an amount to cover the cost of
purchasing portfolio securities, including 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 such securities.

                                OCTOBER 31, 2020

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's
portfolio. When shares are redeemed for cash, the Authorized Participant may
also be assessed an amount to cover other costs, including 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
portfolio securities sold in connection with the redemption.

                              6. DISTRIBUTION PLAN

The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule
12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is
authorized to pay an amount up to 0.25% of its average daily net assets each
year to reimburse First Trust Portfolios L.P. ("FTP"), the distributor of the
Fund, for amounts expended to finance activities primarily intended to result in
the sale of Creation Units or the provision of investor services. FTP may also
use this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before March 31, 2022.

                               7. INDEMNIFICATION

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

                                8. OTHER MATTERS

By operation of law, the Fund now operates as a diversified open-end management
investment company as defined in Section 5(b) of the 1940 Act.

                              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
were no subsequent events requiring recognition or disclosure in the financial
statements that have not already been disclosed.


                                                                         Page 37

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 Enhanced Short Maturity ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2020, 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, 2020, 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, 2020, 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
reasonable basis for our opinion.

/s/ Deloitte & Touche LLP

Chicago, Illinois
December 22, 2020

We have served as the auditor of one or more First Trust investment companies
since 2001.

                      PROXY VOTING POLICIES AND PROCEDURES

A description of the policies and procedures that the Trust uses to determine
how to vote proxies and information on how the Fund voted proxies relating to
its portfolio securities during the most recent 12-month period ended June 30 is
available (1) without charge, upon request, by calling (800) 988-5891; (2) on
the Fund's website at www.ftportfolios.com; and (3) on the Securities and

                               PORTFOLIO HOLDINGS

The Fund files portfolio holdings information for each month in a fiscal quarter
within 60 days after the end of the relevant fiscal quarter on Form N-PORT.
Portfolio holdings information for the third month of each fiscal quarter will
be publicly available on the SEC's website at www.sec.gov. The Fund's complete
schedule of portfolio holdings for the second and fourth quarters of each fiscal
year is included in the semi-annual and annual reports to shareholders,
respectively, and is filed with the SEC on Form N-CSR. The semi-annual and
annual report for the Fund is available to investors within 60 days after the
period to which it relates. The Fund's Forms N-PORT and Forms N-CSR are
available on the SEC's website listed above.

                            FEDERAL TAX INFORMATION

Distributions paid to foreign shareholders during the Fund's fiscal year ended
October 31, 2020 that were properly designated by the Fund as "interest-related
dividends" or "short-term capital gain dividends," may not be subject to federal
income tax provided that the income was earned directly by such foreign
shareholders.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2020, 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 large
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
not concentrated.

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.

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.


                                                                         Page 39

                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                               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 Enhanced Short Maturity ETF (the
"Fund"). The Board approved the continuation of the Agreement for a one-year
period ending June 30, 2021 at a meeting held on June 8, 2020. 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
reasonable 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 May 11, 2020 and June 8, 2020, 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 fall-out benefits to the Advisor and its affiliate, First Trust

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                          OCTOBER 31, 2020 (UNAUDITED)

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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Fund since the onset of the
COVID-19 pandemic. 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 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 considered the background and experience of the persons
responsible for the day-to-day management of the Fund's investments. 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 objective, 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 May 11, 2020 meeting, described to the Board
the scope of its ongoing investment in additional infrastructure and personnel
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
objective, 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 noted that the Advisor had previously agreed to waive a portion of its
unitary fee in an amount equal to 0.05% of the Fund's average daily net assets
until at least March 1, 2021 and to also reduce the unitary fee to the extent of
acquired fund fees and expenses of shares of investment companies advised by the
Advisor that are held by the Fund. The Board received and reviewed information
showing the advisory or unitary 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, after taking
into account the contractual fee waiver, 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 May 11, 2020 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
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, 2019
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 underperformed the Performance Universe median for the one-, three- and
five-year periods ended December 31, 2019. The Board also noted that the Fund
outperformed the benchmark index for the one-, three- and five-year periods
ended December 31, 2019. The Board noted the Advisor's discussion of the Fund's
performance at the May 11, 2020 meeting.

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                          OCTOBER 31, 2020 (UNAUDITED)

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board considered that the Advisor had
identified as a fall-out 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 fall-out 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.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Fund primarily holds assets that
are highly liquid investments, the Fund has not adopted a highly liquid
investment minimum.

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


                                                                         Page 43

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                          OCTOBER 31, 2020 (UNAUDITED)

                                  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 Enhanced Short Maturity 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, 2019, the amount of remuneration paid (or to
be paid) by First Trust in respect of the Fund is $7,757,913. This figure is
comprised of $1,486,412 paid (or to be paid) in fixed compensation and
$6,271,501 paid (or to be paid) in variable compensation. There were a total of
19 beneficiaries of the remuneration described above. Those amounts include
$1,032,165 paid (or to be paid) to senior management of First Trust and
$6,725,748 paid (or to be paid) to other employees whose professional activities
have a material impact on the risk profiles of First Trust or the Fund
(collectively, "Code Staff").

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.

                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS


This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and/or First Trust Global Portfolios Ltd. ("FTGP");

together, the "Sub-Advisors") and their respective representatives, taking into
account the information currently available to them. Forward-looking statements
include all statements that do not relate solely to current or historical fact.
For example, forward-looking statements include the use of words such as
"anticipate," "estimate," "intend," "expect," "believe," "plan," "may,"
"should," "would" or other words that convey uncertainty of future events or
outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
the series of First Trust Exchange-Traded Fund IV (the "Trust") described in
this report (First Trust Strategic Income ETF; hereinafter referred to as the
"Fund") to be materially different from any future results, performance or
achievements expressed or implied by the forward-looking statements. When

arise after the date hereof.

                        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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

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

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Strategic Income ETF (the "Fund"), which contains detailed information about the
Fund for the twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

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

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

FIRST TRUST STRATEGIC INCOME ETF (FDIV)

The primary investment objective of First Trust Strategic Income ETF (the
"Fund") is to seek risk-adjusted income. The Fund's secondary investment
objective is capital appreciation. The Fund is a multi-manager, multi-strategy
actively managed exchange-traded fund. First Trust Advisors L.P. ("First Trust"
or the "Advisor") serves as the Fund's investment advisor. The Advisor's
Investment Committee determines the Fund's strategic allocation among various
general investment categories and allocates the Fund's assets to portfolio
management teams comprised of personnel of the Advisor and/or a sub-advisor
(each, a "Management Team"), which employ their respective investment
strategies. Shares of the Fund are listed on The Nasdaq Stock Market LLC under
the ticker symbol "FDIV."

The Fund's investment categories are: (i) high yield corporate bonds, commonly
referred to as "junk" bonds, and first lien senior secured floating rate bank
loans; (ii) mortgage-related investments; (iii) preferred securities; (iv)
international sovereign bonds, including securities issued by emerging markets
countries; (v) equity securities of Energy Infrastructure Companies(1), certain
of which are master limited partnerships ("MLPs"); and (vi) dividend paying U.S.
exchange-traded equity securities and depositary receipts. The Management Teams
may utilize a related option overlay strategy and/or derivative instruments in
implementing their respective investment strategies for the Fund. Additionally,
the Management Teams may seek to gain exposure to the Fund's investment
categories directly or through investments in exchange-traded funds. The Advisor
expects that the Fund may at times invest significantly in other exchange-traded
funds, including but not limited to, other exchange-traded funds that are
advised by the Advisor; accordingly, the Fund may operate principally as a "fund
of funds," but will not necessarily operate as such at all times. The Fund seeks
to achieve its objectives by having each Management Team focus on those
securities within its respective investment category. The Fund may add or remove
investment categories or Management Teams at the discretion of the Advisor.

</TABLE>


Total returns for the period since inception are calculated from the inception
date of the Fund. "Average Annual Total Returns" represent the average annual
change in value of an investment over the period indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the period
indicated.

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

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

      Rate Preferred Securities Index, ICE BofA U.S. High Yield Index, Bloomberg
      Barclays EM USD Aggregate Index and Bloomberg Barclays U.S. MBS Index. An
      index does not charge management fees or brokerage expenses, and no such

      are unmanaged and an investor cannot invest directly in an index. The
      Blended Index returns are calculated by using the monthly return of the
      six indices during each period shown above. At the beginning of each month
      the six indices are rebalanced to a 16.66 percentage weighting for each
      index to account for divergence from the percentage weighting that
      occurred during the course of each month. The monthly returns are then

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 indices do
not actually hold a portfolio of securities and therefore do 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.

FIRST TRUST STRATEGIC INCOME ETF

The Fund is an actively managed exchange-traded fund. The primary investment
objective of the Fund is to seek risk-adjusted income. The Fund's secondary
investment objective is capital appreciation. There is no assurance that the
Fund's investment objectives will be achieved. The Fund may not be appropriate
for all investors.

MARKET RECAP

Suffice it to say that much has changed with the state of the economy over the
past 12 months. A year ago, a top concern was that U.S. economic growth was
being tempered by the Trump Administration's aggressive use of trade tariffs
against some of the major trading partners of the U.S. The trade tariff program
was enacted in March 2018 with the initial intent of only targeting imported

steel and aluminum. The program, however, quickly expanded to include hundreds
of billions of dollars of other imported goods and services. The tariffs are
largely still in place as of November 2020 which means the program has been
operational for some 32 months. Throughout this period, the epicenter of the
trade conflict has clearly been between the U.S. and China. While the goal in
the Trump Administration was to grow the economy at a 3.00% or higher rate,
after his tax reform bill was signed into law in December 2017, from June 30,
2018 (first full quarter of tariffs) through December 31, 2019, real U.S. gross
domestic product ("GDP") averaged just 2.2%, according to data from the Bureau
of Economic Analysis. The tariffs trumped lower tax rates, in our opinion. In
February 2020, the White House admitted that President Donald J. Trump's stance
on trade depressed economic growth and business investment, according to
Bloomberg.

On top of the tariffs, the world was introduced to a new coronavirus in the
first quarter of 2020, known as COVID-19. Ironically, its origin was traced back
to China, the poster country for the Trump Administration's trade war. Since
most people are well aware of the evolution of the virus and its destructive
nature, attention will be given to its impact on economic growth. To put it
bluntly, COVID-19 threw the U.S. economy into recession. Real U.S. GDP growth
came in at an annualized -5.0% and -31.4% in the first and second quarters of
2020, according to the Bureau of Economic Analysis. The good news is the damage
looks like it may be limited to just those two quarters. Thanks in large part to
the trillions of dollars of fiscal and monetary stimulus provided by the U.S.
federal government, economic growth surged back by an annualized 33.1% in the
third quarter of 2020. Americans have learned to adapt to COVID-19, especially
when it comes to retail shopping. Adobe Analytics estimates that online holiday
shopping in 2020 (November and December) will surge 33% year-over-year to a
record $189 billion, according to CNBC. That equates to around two years of
e-commerce growth in just one season. Adobe noted that online sales could exceed
$200 billion if consumers receive another round of government stimulus checks or
if brick-and-mortar stores are forced to shut down due to the spread of
COVID-19. Americans are adept at adapting under pressure, in our opinion. Some
health care experts, such as the World Health Organization, are hoping for a
COVID-19 vaccine to be initially available by year-end, and then on a broader
scale by the midpoint of 2021.

If there is a silver lining from this ordeal it could be the extraordinary level
of guidance offered by the Federal Reserve (the "Fed"), which is likely
unprecedented. In September 2020, the Fed stated that it expects to hold
short-term interest rates near zero until two things happen: (1) the U.S.
unemployment rate is back to normal (around a 4.0% unemployment rate), and (2)
inflation is running at or above 2.0%. Brian Wesbury, Chief Economist at First
Trust Advisors L.P., notes that the Fed does not expect to achieve both goals
until 2024. We believe that one of the Fed's motivations in promoting a
multi-year commitment to a near zero interest rate monetary policy is to
incentivize risk-taking. By holding interest rates low, the Fed is essentially
disincentivizing saving. This suggests the Fed wants individuals to invest their
capital in risk assets and is offering valuable guidance on its monetary policy
to instill confidence in the markets, in our opinion.

PERFORMANCE ANALYSIS/FUND

The Fund generated a net asset value ("NAV") return of -7.19% for the 12-month
period ended October 31, 2020. During the same period, the Blended Index
generated a return of -5.91%. The Blended Index is equally weighted to include
these six indices: the Alerian MLP Index, Dow Jones U.S. Select Dividend Index,
ICE BofA Fixed Rate Preferred Securities Index, ICE BofA U.S. High Yield Index,
Bloomberg Barclays EM USD Aggregate Index and Bloomberg Barclays U.S. MBS Index.

The Fund invests in six investment categories which are: high-yield corporate
bonds and first lien senior secured floating-rate bank loans, mortgage-related
investments, preferred securities, international sovereign bonds, equity
securities of Energy Infrastructure Companies, and dividend-paying U.S.
exchange-traded equity securities and depositary receipts. The Fund may seek
exposure to these investment categories directly or through investment in
exchange-traded funds. The weight assigned to each investment category is
determined on a periodic basis. As of October 31, 2020, the highest-weighted
investment category was the dividend-paying U.S. exchange-traded equity
securities and the lowest-weighted investment category was mortgage-related
investments. The investment categories of mortgage-related investments,
preferred securities, and high-yield corporate bonds and floating-rate bank
loans were the only investment categories that had positive performance for the
one-year period.

The performance for the high-yield corporate bonds and floating-rate bank loans
had a positive impact on the overall performance of the Fund. Specifically
driving the bank loan high-yield bond performance within the Fund was the Fund's
de minimis exposure to the energy industry, and strong performance in the
healthcare industry. Partially offsetting these contributors were the Fund's
allocation and asset selection within the leisure industry.

Mortgage-related investments had the largest positive impact on the overall Fund
performance during the 12-month period ended October 31, 2020. Mortgages
outperformed due to the combination of declining interest rates and spread
tightening associated with the Federal Reserve purchases of the sector. Going
forward, we expect mortgage spreads to continue tightening which will improve


                                                                          Page 5

outcomes for mortgage investments. We believe that potential for improved
performance within the agency mortgage market is greatest for structure holdings
within the collateral mortgage obligation (CMOs). The portfolio maintains
investments in the CMO sector. In addition, we expect, over the near term, mild
upward pressure on interest rates, but overall that general interest rates will
remain stable and bounded by an accommodated Fed policy, which should minimize
convexity costs and improve mortgage performance. The portfolio maintains a
defensive duration but may increase risk should interest rates rise and mortgage
securities become more attractive.

In spite of volatile conditions in the market, the performance of preferred
securities had a positive impact on the overall performance of the Fund. The
preferred market began the period from a position of strength supported by solid
underlying credit fundamentals and supportive central bank policies prior to the
onset of the global pandemic. The harsh sell-off in the preferred securities
market in response to the pandemic in March 2020 was fairly quickly reversed as
rates dropped across the U.S. Treasury yield curve following the unprecedented
response of global central banks. A consequence of the flattened yield curve was
the outperformance of long duration securities, while floating rate and short
duration securities underperformed. Spread decompression between investment
grade and non-investment grade securities also occurred due to the economic
slowdown. Nonetheless, we remain confident in the outlook for preferred
securities held by the Fund, as issuer credit fundamentals are stable along with
sufficient liquidity and an increase in the availability of favorable security
structures.

The performance of international sovereign bonds had a positive impact on the
overall performance of the Fund. Over the past year, U.S. dollar denominated
emerging market debt has outperformed local currency denominated emerging market
debt primarily as emerging market currencies lagged the risk on rebound seen
since the pandemic volatility witnessed in March. The international sovereign
bond sleeve favored local currency debt over the period due to the deep
undervaluation of emerging market currencies and despite the recent lagged
performance this view is maintained. The weakening trend we have seen developing
in the U.S. Dollar has helped the outlook for emerging market currencies and any
strengthening in these currencies should act as a positive multiplier for local
currency denominated debt going forward.

The performance of the Energy Infrastructure Companies held in the Fund
detracted from the overall performance. Negative sentiment across the entire
energy sector weighed on the pipeline-related master limited partnerships
("MLPs") and C-Corporations more than offsetting the positive contributions from
regulated utilities.

The dividend-paying U.S. exchange-traded equity securities had the largest
negative impact on overall Fund performance. In terms of sectors, performance
was hurt most significantly by securities in the financials sector followed by
utilities, real estate, materials and communication services sectors to a lesser
extent, while it was helped only by industrials. In terms of industries,
detractors were led by exposure to the following: banks, thrifts & mortgage
finance, electric utilities, equity real estate investment trusts ("REITs"),
distributors and diversified telecommunication services. Industry contributors
included exposure to trading companies & distributors, hotels, restaurants &
leisure and machinery. A breakdown of performance by market-cap reveals that all
segments detracted from performance, led by small-cap holdings which dropped in
value more than those held in the large and mid-cap market-segments.

MARKET/FUND OUTLOOK

We believe that income-oriented investors have been given the green light from
the Fed to assume more risk in order to generate higher returns. Here are two
barometers reflecting optimism with respect to Corporate America:

Corporate Earnings/Revenue Growth: Bloomberg's consensus earnings growth rate
estimates for 2021 and 2022 for the S&P 500(R) Index were 22.39% and 17.06%,
respectively, as of October 30, 2020. These growth rates represent a significant
rebound from the -17.70% estimate for 2020. We believe that corporate earnings
determine the direction of stock prices over time. From 1926-2019, the S&P
500(R) Index posted an average annual total return of 10.20%, according to
Morningstar/Ibbotson Associates. The 2021 and 2022 consensus revenue (sales)
growth rate estimates for the S&P 500(R) Index were 7.89% and 6.90%,
respectively, as of October 30, 2020, according to Bloomberg. These too
represent an encouraging turnaround from the -3.49% estimate for 2020.

S&P 500 Index Cash Holdings: In the first quarter of 2020 (most recent quarter
available), preliminary data put S&P 500 Industrials (Old) cash and equivalents
at an all-time high of $1.68 trillion, according to S&P Dow Jones Indices. The
S&P 500(R) Industrials (Old) calculation does not include cash holdings from
Financials, Utilities and Transportation companies. We believe that figure
suggests that S&P 500 companies have a record amount of dry powder that could be
used to either support or increase dividends, buy back stock, pay down debt,
invest in plant and equipment or pursue mergers and acquisitions.

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.

      table multiplied by the average account value over the period (May 1, 2020
      through October 31, 2020), multiplied by 184/366 (to reflect the six-month
      period).

(a)   The Fund received a reimbursement from the Advisor in the amount of $3,457
      in connection with a trade error, which represents less than $0.01 per
      share. Since the Advisor reimbursed the Fund, there was no effect on the
      Fund's total return.

(b)   Total return is calculated assuming an initial investment made at the net
      asset value at the beginning of the period, reinvestment of all
      distributions at net asset value during the period, and redemption at net
      asset value on the last day of the period. 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. Total return is
      calculated for the time period presented and is not annualized for periods
      of less than a year. The total returns would have been lower if certain
      fees had not been waived by the Advisor.

(c)   The Fund indirectly bears its proportionate share of fees and expenses
      incurred by the underlying funds in which the Fund invests. This ratio
      does not include these indirect fees and expenses.

(d)   Includes excise tax. If this excise tax expense was not included, the
      total and net expense ratios would have been 0.85% and 0.49%,
      respectively.

(e)   Portfolio turnover is calculated for the time period presented and is not
      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the First Trust Strategic Income ETF (the "Fund"), which trades under the
ticker "FDIV" on The Nasdaq Stock Market LLC ("Nasdaq"). Unlike conventional
mutual funds, the Fund issues and redeems shares on a continuous basis, at net
asset value ("NAV"), only in large specified blocks consisting of 50,000 shares
called a "Creation Unit." Creation Units are issued and redeemed in-kind for
securities in which the Fund invests and/or cash, and only to and from
broker-dealers and large institutional investors that have entered into
participation agreements. Except when aggregated in Creation Units, the Fund's
shares are not redeemable securities.

The Fund is a multi-manager, multi-strategy actively managed exchange-traded
fund. The Fund's primary investment objective is to seek risk-adjusted income.
The Fund's secondary investment objective is capital appreciation.

First Trust Advisors L.P. ("First Trust" or the "Advisor") is the investment
advisor to the Fund. The following serve as investment sub-advisors to the Fund:
First Trust Global Portfolios Ltd. ("FTGP"); Energy Income Partners, LLC
("EIP"); Stonebridge Advisors LLC ("Stonebridge"); and Richard Bernstein
Advisors LLC ("RBA") (each, a "Sub-Advisor" and together, the "Sub-Advisors").
The Advisor's Investment Committee determines the Fund's strategic allocation
among various general investment categories and allocates the Fund's assets to
portfolio management teams comprised of personnel of the Advisor and/or a
Sub-Advisor (each, a "Management Team"), which employ their respective
investment strategies. The Fund seeks to achieve its objectives by having each
Management Team focus on those securities within its respective investment
category. The Fund may add or remove investment categories or Management Teams
at the discretion of the Advisor.

The Fund's investment categories are: (i) high-yield corporate bonds, commonly
referred to as "junk" bonds, and first lien senior secured floating rate bank
loans; (ii) mortgage-related investments; (iii) preferred securities; (iv)
international sovereign bonds, including securities issued by emerging market
countries; (v) equity securities of Energy Infrastructure Companies(1), certain
of which are master limited partnerships ("MLPs"); and (vi) dividend paying U.S.
exchange-traded equity securities (including common stock) of companies (that
may be domiciled in or outside of the United States) and depositary receipts.
The Management Teams may utilize a related option overlay strategy and/or
derivative instruments in implementing their respective investment strategies
for the Fund. Additionally, the Management Team may seek exposure to these asset
classes directly or through investments in exchange-traded funds ("ETFs"). The
Advisor expects that the Fund may at times invest significantly in other ETFs,
including but not limited to, other ETFs that are advised by the Advisor;
accordingly, the Fund may operate principally as a "fund of funds," but will not
necessarily operate as such at all times.

                       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.

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

(1)   Energy Infrastructure Companies are publicly-traded MLPs or limited
      liability companies that are taxed as partnerships; entities that control
      MLPs, entities that own general partner interests in an MLP, or MLP
      affiliates (such as I-shares or I-units); U.S. and Canadian energy yield
      corporations ("yieldcos"); pipeline companies; utilities; and other
      companies that are involved in operating or providing services in support
      of infrastructure assets such as pipeline, power transmission,
      terminalling and petroleum and natural gas storage in the petroleum,
      natural gas and power generation industries.

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                                OCTOBER 31, 2020

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Advisor's Pricing Committee in
accordance with valuation procedures adopted by the Trust's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. All securities and other assets of the Fund
initially expressed in foreign currencies will be converted to U.S. dollars
using exchange rates in effect at the time of valuation. The Fund's investments
are valued as follows:

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

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

      Common stocks, preferred stocks, MLPs 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 principal market for such securities.

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

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


                                                                         Page 19

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                                OCTOBER 31, 2020

Fair valuation of a debt security will be based on the consideration of all
available information, including, but not limited to, the following:

            1)    the fundamental business data relating to the issuer;

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

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

            4)    the financial statements of the issuer;

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

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

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

            8)    the coupon payments;

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

           10)    the business prospects of the 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);

           11)    the economic, political and social prospects/developments of
                  the country of issue and the assessment of the country's
                  government leaders/officials (for sovereign 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.

Fair valuation of an equity security will be based on the consideration of all
available information, including, but not limited to, the following:

            1)    the type of security;
            2)    the size of the holding;
            3)    the initial cost of the security;
            4)    transactions in comparable securities;
            5)    price quotes from dealers and/or third-party pricing services;
            6)    relationships among various securities;
            7)    information obtained by contacting the issuer, analysts, or
                  the appropriate stock exchange;
            8)    an analysis of the issuer's financial statements; and
            9)    the existence of merger proposals or tender offers that might
                  affect the value of the security.

Because foreign markets may be open on different days than the days during which
investors may transact in the shares of the Fund, the value of the Fund's
securities may change on the days when investors are not able to transact in the
shares of the Fund. The value of the securities denominated in foreign
currencies is converted into U.S. dollars using exchange rates determined daily
as of the close of regular trading on the NYSE.

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.

                                OCTOBER 31, 2020

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, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

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.

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.

Distributions received from the Fund's investments in MLPs generally are
comprised of return of capital and investment income. The Fund records estimated
return of capital and investment income based on historical information
available from each MLP. These estimates may subsequently be revised based on
information received from the MLPs after their tax reporting periods are
concluded.

Distributions received from the Fund's investments in real estate investment
trusts ("REITs") may be comprised of return of capital, capital gains and
income. The actual character of the amounts received during the year is not
known until after the REITs' fiscal year end. The Fund records the character of
distributions received from the REITs during the year based on estimates
available. The characterization of distributions received by the Fund may be
subsequently revised based on information received from the REITs after their
tax reporting periods conclude.

C. FUTURES CONTRACTS

The Fund purchases or sells (i.e., is long or short) exchange-listed futures
contracts to hedge against 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 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.

                                OCTOBER 31, 2020

D. FOREIGN CURRENCY

The books and records of the Fund are maintained in U.S. dollars. Foreign
currencies, investments and other assets and liabilities are translated into
U.S. dollars at the exchange rates prevailing at the end of the period.
Purchases and sales of investments and items of income and expense are
translated on the respective dates of such transactions. Unrealized gains and
losses on assets and liabilities, other than investments in securities, which
result from changes in foreign currency exchange rates have been included in
"Net change in unrealized appreciation (depreciation) on foreign currency
translation" on the Statement of Operations. Unrealized gains and losses on
investments in securities which result from changes in foreign exchange rates
are included with fluctuations arising from changes in market price and are
included in "Net change in unrealized appreciation (depreciation) on investments
- Unaffiliated" on the Statement of Operations. Net realized foreign currency
gains and losses include the effect of changes in exchange rates between trade
date and settlement date on investment security transactions, foreign currency
transactions and interest and dividends received is included in "Net realized
gain (loss) on foreign currency transactions" on the Statement of Operations.
The portion of foreign currency gains and losses related to fluctuation in
exchange rates between the initial purchase settlement date and subsequent sale
trade date is included in "Net realized gain (loss) on investments -
Unaffiliated" on the Statement of Operations.

E. 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.

F. 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.

G. 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.

H. 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.

I. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

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 significantly modified 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, 2020 and 2019 was as follows:



Distributions paid from:                              2020             2019
Ordinary income...............................   $    2,785,206   $    3,409,004
Capital gains.................................               --               --
Return of capital.............................           88,048               --


As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:



Undistributed ordinary income.................   $           --
Accumulated capital and other gain (loss).....       (6,090,400)
Net unrealized appreciation (depreciation)....       (1,267,899)


J. 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.


                                                                         Page 23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                                OCTOBER 31, 2020

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 2017,
2018, 2019, and 2020 remain open to federal and state audit. As of October 31,
2020, 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, 2020, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $6,090,400.

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, 2020, 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 and in-kind transactions. The results of
operations and net assets were not affected by these adjustments. For the fiscal
year ended October 31, 2020, the adjustments for the Fund were as follows:




                               ACCUMULATED
           ACCUMULATED         NET REALIZED
          NET INVESTMENT       GAIN (LOSS)
          INCOME (LOSS)       ON INVESTMENTS      PAID-IN CAPITAL
          --------------      --------------      ---------------
          $      692,811      $      135,918      $      (828,729)


K. EXPENSES

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

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

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for supervising 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.

The Fund and First Trust have retained the Sub-Advisors to provide
recommendations to the Advisor regarding the selection and ongoing monitoring of
the securities in the Fund's investment portfolio. First Trust executes all
transactions on behalf of the Fund, with the exception of the securities that
are selected by FTGP. EIP, an affiliate of First Trust, provides recommendations
regarding the selection of MLP securities for the Fund's investment portfolio
and provides ongoing monitoring of the MLP securities, MLP affiliate and energy
infrastructure securities in the Fund's investment portfolio selected by EIP.
EIP exercises discretion only with respect to assets of the Fund allocated to
EIP by the Advisor. FTGP, an affiliate of First Trust, selects international
sovereign debt securities for the Fund's investment portfolio and provides
ongoing monitoring of the international sovereign debt securities in the Fund's
investment portfolio selected by FTGP. RBA provides recommendations regarding
longer term investment strategies that combine top-down, macroeconomic analysis
and quantitatively-driven portfolio construction. RBA exercises discretion only
with respect to assets allocated to RBA by the Advisor. Stonebridge, an
affiliate of First Trust, provides recommendations regarding the selection and
ongoing monitoring of the preferred and hybrid securities in the Fund's
investment portfolio.

Pursuant to the Investment Management Agreement between the Trust and Advisor,
First Trust will supervise the Sub-Advisors and their management of the
investment of the Fund's assets and will pay EIP, FTGP, RBA and Stonebridge for
their services as the Fund's sub-advisors. EIP and FTGP each receive a
sub-advisory fee from First Trust equal to 40% of any remaining monthly
investment management fee paid to First Trust for the average daily net assets
allocated to the Sub-Advisor after the average Fund expenses accrued during the
most recent twelve months are subtracted from the investment management fee in a
given month. RBA and Stonebridge each receive annual sub-advisory fees equal to
0.20% of the average daily net assets on the assets of the Fund allocated to the
Sub-Advisor by First Trust. First Trust will also be 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") with the exception of those attributable to affiliated Funds,
brokerage commissions and other expenses connected with the execution of
portfolio transactions, distribution and service fees pursuant to a Rule 12b-1
plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust
an annual unitary management fee equal to 0.85% of its average daily net assets.
The total of the unitary management fee, acquired fund fees and expenses, and
other excluded expenses represents the Fund's total annual operating expenses.
Pursuant to a contractual agreement between the Trust, on behalf of the Fund,
and First Trust, the management fees paid to First Trust will be reduced by the
proportional amount of the acquired fund fees and expenses of the shares of
investment companies held by the Fund so that the Fund would not bear the
indirect costs of holding them, provided that the investment companies are
advised by First Trust. This contractual agreement shall continue until the
earlier of (i) its termination at the direction of the Trust's Board of Trustees
or (ii) the termination of the Fund's management agreement with First Trust.
First Trust does not have the right to recover the fees waived that are
attributable to acquired fund fees and expenses on the shares of investment
companies advised by First Trust. During the fiscal year ended October 31, 2020,
the Advisor waived fees of $265,076.

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

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,
defined- outcome fund or is an index fund. Additionally, the Lead Independent
Trustee and the Chairmen 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 Chairmen will rotate every
three years. The officers and "Interested" Trustee receive no compensation from
the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The cost of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments and in- kind transactions for the
fiscal year ended October 31, 2020, were $466,645 and $79,932,054, respectively.
The proceeds from sales and paydowns of U.S. Government securities and non-U.S.
Government securities, excluding short-term investments and in-kind transactions
for the fiscal year ended October 31, 2020, were $4,902,178 and $74,651,340,
respectively.

For the fiscal year ended October 31, 2020, the cost of in-kind purchases and
proceeds from in-kind sales were $3,803,623 and $25,098,676, respectively.

                           5. DERIVATIVE TRANSACTIONS

As of October 31, 2020, the Fund had no derivative instruments.

The following table presents the amount of net realized gain (loss) and change
in net unrealized appreciation (depreciation) recognized for the fiscal year
ended October 31, 2020, on derivative instruments, as well as the primary
underlying risk exposure associated with the instruments.

                 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker-dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). In order to purchase Creation Units of the Fund, an
Authorized Participant must deposit (i) a designated portfolio of securities
determined by First Trust (the "Deposit Securities") and generally make or
receive a cash payment referred to as the "Cash Component," which is an amount
equal to the difference between the NAV of the Fund Shares (per Creation Unit
Aggregation) and the market value of the Deposit Securities, and/or (ii) cash in
lieu of all or a portion of the Deposit Securities. The Fund's Creation Units
are generally issued and redeemed for cash. If the Cash Component is a positive
number (i.e., the NAV per Creation Unit Aggregation exceeds the Deposit Amount),
the Authorized Participant will deliver the Cash Component. If the Cash
Component is a negative number (i.e., the NAV per Creation Unit Aggregation is
less than the Deposit Amount), the Authorized Participant will receive the Cash
Component.

Authorized Participants purchasing Creation Units must pay to BNYM, as transfer
agent, a creation transaction fee (the "Creation Transaction Fee") regardless of
the number of Creation Units purchased in the transaction. The Creation
Transaction Fee may increase or decrease with changes in the Fund's portfolio.
The price for each Creation Unit will equal the daily NAV per share 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 or
stamp taxes. When the Fund permits an Authorized Participant to substitute cash
or a different security in lieu of depositing one or more of the requisite
Deposit Securities, the Authorized Participant may also be assessed an amount to
cover the cost of purchasing the Deposit Securities and/or disposing of the
substituted securities, including 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 such Deposit Securities and/or
substitute securities.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's
portfolio. The Fund reserves the right to effect redemptions in cash. An
Authorized Participant may request cash redemption in lieu of securities;
however, the Fund may, in its discretion, reject any such request.

                              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, 2022.

                               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. OTHER MATTERS

By operation of law, the Fund now operates as a diversified open-end management
investment company as defined in Section 5(b) of the 1940 Act.

                             10. SUBSEQUENT EVENTS

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

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 Strategic Income ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2020, 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, 2020, 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, 2020, 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
reasonable basis for our opinion.

                              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 large
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
not concentrated.

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.

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.

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.


                                                                         Page 29

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                      ADVISORY AND SUB-ADVISORY AGREEMENTS

BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AND
SUB-ADVISORY AGREEMENTS

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 "Advisory Agreement") between the Trust, on
behalf of First Trust Strategic Income ETF (the "Fund"), and First Trust
Advisors L.P. (the "Advisor"); the Investment Sub-Advisory Agreement (the
"Stonebridge Sub-Advisory Agreement") among the Trust, on behalf of the Fund,
the Advisor and Stonebridge Advisors LLC ("Stonebridge"); the Investment
Sub-Advisory Agreement (the "Richard Bernstein Sub-Advisory Agreement") among
the Trust, on behalf of the Fund, the Advisor and Richard Bernstein Advisors LLC
("Richard Bernstein"); the Investment Sub-Advisory Agreement (the "Energy Income
Partners Sub-Advisory Agreement") among the Trust, on behalf of the Fund, the
Advisor and Energy Income Partners, LLC ("Energy Income Partners"); and the
Investment Sub-Advisory Agreement (the "First Trust Global Sub-Advisory
Agreement") among the Trust, on behalf of the Fund, the Advisor and First Trust
Global Portfolios Ltd. ("First Trust Global"). The Stonebridge Sub-Advisory
Agreement, the Richard Bernstein Sub-Advisory Agreement, the Energy Income
Partners Sub-Advisory Agreement and the First Trust Global Sub-Advisory
Agreement are collectively referred to as the "Sub-Advisory Agreements."
Stonebridge, Richard Bernstein, Energy Income Partners and First Trust Global
are each referred to as a "Sub-Advisor" and collectively as the "Sub-Advisors."
The Sub-Advisory Agreements together with the Advisory Agreement are referred to
as the "Agreements." The Board approved the continuation of the Agreements for a
one-year period ending June 30, 2021 at a meeting held on June 8, 2020. The
Board determined that the continuation of the Agreements 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 reasonable 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 May 11, 2020 and June 8, 2020, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor and each Sub-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 and
each Sub-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 sub-advisory fee
rates for the Fund as compared to fees charged to other clients of the

Sub-Advisors; 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 and each Sub-Advisor to realize
economies of scale, if any; profitability and other financial data for the
Advisor; financial data for each Sub-Advisor; any fall-out benefits to the
Advisor and its affiliates, First Trust Portfolios L.P. ("FTP") and First Trust
Global, and the Sub-Advisors; and information on the Advisor's and each
Sub-Advisor's compliance programs. The Board reviewed initial materials with the
Advisor at the meeting held on May 11, 2020, prior to which the Independent
Trustees and their counsel met separately to discuss the information provided by
the Advisor and the Sub-Advisors. Following the May 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 8, 2020
meeting, as well as at the meeting held that day. The Board considered
supplemental information provided by the Advisor and each Sub-Advisor on the
operations of the Advisor and each Sub-Advisor, respectively, and the
performance of the Fund since the onset of the COVID-19 pandemic. The Board
applied its business judgment to determine whether the arrangements between the
Trust and the Advisor and among the Trust, the Advisor and each Sub-Advisor
continue to be reasonable business arrangements from the Fund's perspective. The
Board determined that, given the totality of the information provided with
respect to the Agreements, the Board had received sufficient information to
renew the Agreements. The Board considered that shareholders chose to invest or
remain invested in the Fund knowing that the Advisor and the Sub-Advisors manage
the Fund and knowing the Fund's unitary fee.

In reviewing the Agreements, the Board considered the nature, extent and quality
of the services provided by the Advisor and the Sub-Advisors under the
Agreements. The Board considered that the Fund is an actively-managed ETF and
employs a multi-manager/multi-sleeve structure. With respect to the Advisory
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, including the oversight of the
Sub-Advisors and the strategic and tactical asset allocations among internal
management teams and the Sub-Advisors performed by members of the Advisor's
Investment Committee, as well as the background and experience of the persons
responsible for such services. In addition to materials provided by the Advisor,
at the May 11, 2020 meeting, the Board received a presentation from members of
the Investment Committee discussing the services that the Investment Committee
provides to the Fund. The Board considered that Stonebridge and Richard
Bernstein act as non-discretionary managers providing model portfolio
recommendations to the Advisor, and that although First Trust Global and Energy
Income Partners act as discretionary investment advisors, the Advisor executes
the Fund's portfolio trades. The Board noted that members of the Advisor's
Mortgage Securities Team and Leveraged Finance Investment Team participate in
the management of the Fund and considered the experience of each Team and noted
the Board's prior meetings with members of each Team. The Board noted that the
Advisor oversees management of the Fund's investments, 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, each
Sub-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 May 11, 2020 meeting, described to the Board the scope of its ongoing
investment in additional infrastructure and personnel to maintain and improve
the quality of services provided to the Fund and the other funds in the First
Trust Fund Complex. With respect to the Sub-Advisory Agreements, the Board noted
that the Fund is an actively-managed ETF and the Sub-Advisors actively manage
the Fund's investments. The Board reviewed the materials provided by each
Sub-Advisor and considered the services that each Sub-Advisor provides to the
Fund, including each Sub-Advisor's discretionary or non-discretionary
management, as applicable, of the portion of the Fund's assets allocated to it.
In considering each Sub-Advisor's services to the Fund, the Board noted the
background and experience of each Sub-Advisor's portfolio management team and
the Board's prior meetings with members of each portfolio management team. The
Board also received a presentation from representatives of Energy Income
Partners at the June 8, 2020 meeting. 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 and each
Sub-Advisor under the Agreements have been and are expected to remain
satisfactory and that the Advisor and the Sub-Advisors have managed the Fund
consistent with the Fund's investment objectives, policies and restrictions.

The Board considered the unitary fee rate payable by the Fund under the Advisory
Agreement for the services provided. The Board noted that the Advisor pays each
Sub-Advisor a separate sub-advisory fee from the unitary fee. The Board
considered that as part of the unitary fee the Advisor is responsible for the
Fund's expenses, including the cost of sub-advisory, transfer agency, custody,
fund administration, legal, audit and other services and license fees, if any,
but excluding the fee payment under the Advisory Agreement and interest, taxes,
acquired fund fees and expenses, 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 noted that the Advisor had previously agreed to waive its unitary fee
to the extent of acquired fund fees and expenses of shares of investment


                                                                         Page 31

                          OCTOBER 31, 2020 (UNAUDITED)

companies advised by the Advisor that are held by the Fund. The Board received
and reviewed information showing the advisory or unitary 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 and the Sub-Advisors 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, after taking into account fee waivers, was below the median
total (net) expense ratio of the peer funds in the Expense Group. With respect
to the Expense Group, the Board, at the May 11, 2020 meeting, discussed with
Broadridge its methodology for assembling peer groups and discussed with the
Advisor limitations in creating peer groups for actively-managed ETFs and that
different business models may affect the pricing of services among ETF sponsors.
The Board noted that not all peer funds employ an advisor/sub-advisor management
structure. 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, 2019
to the performance of the funds in the Performance Universe and to that of a
blended benchmark index. Based on the information provided, the Board noted that
the Fund outperformed the Performance Universe median and the blended benchmark
index for the one-, three- and five-year periods ended December 31, 2019.

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 (out of which the Sub-Advisors are compensated)
continues to be reasonable and appropriate in light of the nature, extent and
quality of the services provided by the Advisor and the Sub-Advisors to the Fund
under the Agreements.

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board noted that affiliates of the Advisor
have ownership interests in Stonebridge, Energy Income Partners and First Trust
Global and considered potential fall-out benefits to the Advisor from such
ownership interests. The Board also considered that the Advisor had identified
as a fall out 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 fall-out benefits to the Advisor were not unreasonable.

With respect to the Stonebridge Sub-Advisory Agreement, the Board considered
Stonebridge's expenses in providing investment services to the Fund and noted
Stonebridge's hiring of additional personnel and commitment to add additional
resources if assets increase. The Board did not review the profitability of
Stonebridge with respect to the Fund. The Board noted that the Advisor pays
Stonebridge from the unitary fee, and its understanding that the Fund's
sub-advisory fee rate was the product of an arm's length negotiation. The Board
concluded that the profitability analysis for the Advisor was more relevant. The
Board considered fall-out benefits that may be realized by Stonebridge from its
relationship with the Fund, including potential fall-out benefits to Stonebridge
from the ownership interest of an affiliate of the Advisor in Stonebridge, and
noted Stonebridge's statement that its relationship with the Advisor has helped
it build relationships with Wall Street firms that have preferred and hybrid
securities trading desks, which may lead to access to those firms' research
reports and analysts. The Board noted that Stonebridge acts as non-discretionary
manager providing model portfolio recommendations to the Advisor and does not
provide trade execution services to the Fund. The Board concluded that the
character and amount of potential fall-out benefits to Stonebridge were not
unreasonable.

With respect to the Richard Bernstein Sub-Advisory Agreement, the Board
considered Richard Bernstein's statements about economies of scale. The Board
did not review the profitability of Richard Bernstein with respect to the Fund.
The Board noted that the Advisor pays Richard Bernstein from the unitary fee,
and its understanding that the Fund's sub-advisory fee rate was the product of

an arm's length negotiation. The Board concluded that the profitability analysis
for the Advisor was more relevant. The Board noted the potential fall-out
benefits identified by Richard Bernstein as a result of its relationship with
the Fund and the Advisor. The Board noted that Richard Bernstein acts as
non-discretionary manager providing model portfolio recommendations to the
Advisor and does not provide trade execution services to the Fund. The Board
concluded that the character and amount of potential fall-out benefits to
Richard Bernstein were not unreasonable.

With respect to the Energy Income Partners Sub-Advisory Agreement, the Board
considered that Energy Income Partners' investment services expenses are
primarily fixed in nature, and that Energy Income Partners has made recent
investments in personnel and infrastructure and anticipates that its expenses
will continue to rise due to additions to personnel and system upgrades. The
Board did not review the profitability of Energy Income Partners with respect to
the Fund. The Board noted that the Advisor pays Energy Income Partners from the
unitary fee, and its understanding that the Fund's sub-advisory fee rate was the
product of an arm's length negotiation. The Board concluded that the
profitability analysis for the Advisor was more relevant. The Board considered
fall-out benefits that may be realized by Energy Income Partners from its
relationship with the Fund, including the potential fall-out benefits to Energy
Income Partners from the ownership interest of an affiliate of the Advisor in
Energy Income Partners. The Board noted that Energy Income Partners does not
provide trade execution services on behalf of the Fund. The Board concluded that
the character and amount of potential fall-out benefits to Energy Income
Partners were not unreasonable.

With respect to the First Trust Global Sub-Advisory Agreement, the Board
considered First Trust Global's statements that expenses incurred in providing
services to the Fund are of a fixed nature and that no economies of scale have
been identified from the provision of services to the Fund. The Board did not
review the profitability of First Trust Global with respect to the Fund. The
Board concluded that the profitability analysis for the Advisor was more
relevant. The Board considered the potential fall-out benefits to First Trust
Global from being associated with the Advisor and the Fund. The Board noted that
First Trust Global does not provide trade execution services on behalf of the
Fund. The Board concluded that the character and amount of potential fall-out
benefits to First Trust Global 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 Agreements continue to be fair and reasonable and that the continuation
of the Agreements is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Fund primarily holds assets that
are highly liquid investments, the Fund has not adopted a highly liquid
investment minimum.

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

                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS


This report contains certain forward-looking statements within the meaning of

as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
the series of First Trust Exchange-Traded Fund IV (the "Trust") described in
this report (First Trust Low Duration Opportunities ETF; hereinafter referred to
as the "Fund") to be materially different from any future results, performance
or achievements expressed or implied by the forward-looking statements. When
evaluating the information included in this report, you are cautioned not to

                        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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

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

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


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, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

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


                                                                          Page 1

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

FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)

The primary investment objective of the First Trust Low Duration Opportunities
ETF (the "Fund") 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. The Fund's investment categories are: (i) mortgage-related
investments, including mortgage-backed securities that may be, but are not
required to be, issued or guaranteed by the U.S. government or its agencies or
instrumentalities; (ii) U.S. government securities, including callable agency
securities, which give the issuer (the U.S. government agency) the right to
redeem the security prior to maturity, and U.S. government inflation-indexed
securities; and (iii) high yield debt, commonly referred to as "junk" debt.
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 (as described in (iii) above), illiquid securities, and
derivative instruments. The Fund is diversified.

</TABLE>


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.

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.

MARKET RECAP

The 12-month period ended October 31, 2020 began relatively calmly, being driven
primarily by policy decisions related to the trade war between the U.S. and
China. The onset of the coronavirus ("COVID-19") pandemic triggered an
unprecedented liquidity crisis across global markets, with its effects rippling
through the domestic and global economies and causing profound changes in both
bond and equity market fundamentals, risk factors and valuations. Due to the
nature of this pandemic, the reversal in monetary policy driven by the trade war
was put into overdrive. In response, the Federal Reserve (the "Fed") began a new
phase of seemingly limitless quantitative easing, and reinstated programs that
were last relied upon during the Great Recession of 2008. It also began to roll
out new programs, expanding the range of covered asset classes, and providing a
backstop to the significant dislocations and severe illiquidity that occurred.
The Fed further aided markets with emergency rate cuts totaling 150 basis points
("bps") and setting the lower bound of the Fed Funds rate at 0%. The Fed was not
alone in providing aid, as Congress stepped in with a large stimulus package to
help Americans weather coronavirus and its effects. Treasury issuance as a
result has soared to buoy government spending, however, with the aid of
quantitative easing ("QE") programs and a continued demand for safe haven
assets, Treasury yields plunged to record lows. For example, over the last year,
the 2-Year Treasury yield has declined precipitously by -137 bps to close on
October 31, 2020 at 15 bps, while the 10-Year Treasury fell 82 bps to close the
year at 87.4 bps, with the curve bull steepening. The COVID-19 panic did not
discriminate, affecting nearly every aspect of the broader spread markets,
including Agency Mortgage-Backed Securities ("MBS"), which initially saw large
spread widening moves as Agency MBS spreads widened dramatically from the low
40s Treasury Option-Adjusted Spread ("OAS"), to a wide of 136 OAS. Agency MBS
spreads tightened to close the fiscal year at 64 OAS, as the impact of Fed
programs and legislative support helped improve liquidity and greatly improved
market participants risk appetite.

PERFORMANCE ANALYSIS

During the 12-month period ended October 31, 2020, the Fund returned 1.50% on a
net asset value ("NAV") basis. Since the Fund's inception on November 4, 2014,
the Fund has returned a cumulative 21.01%, net of fees.

During the 12-month period ended October 31, 2020, the ICE BofA 1-5 Year U.S.
Treasury & Agency Index (the "Index") returned 4.11%. Since the Fund's inception
on November 4, 2014, the Index has returned 13.14% on a cumulative basis.

During the 12-month period ended October 31, 2020, the Fund underperformed the
Index by -261 bps, net of fees. Since the Fund's inception, the Fund has
outperformed the Index by 7.87%, net of fees. The Fund is structured to own a
significant percentage of the Fund in MBS, with the majority allocated to the
Agency MBS sector, whereas the benchmark is a pure treasury and agency index.
MBS, both Agency and to a greater extent, Non-Agency Residential Mortgage-Backed
Securities ("RMBS"), each experienced substantial widening during the severe
illiquidity that gripped the fixed income markets during the early stages of the
COVID-19 pandemic unfolding. As American markets digested the rapid pace of
lockdowns, uncertainties on future economic health, and the Fed's rapidly
evolving market support, treasury yields plunged, in an outright flight to
quality. This was detrimental to the Fund in terms of matching the benchmark's
performance, due to the negative convexity associated with mortgage securities
as well as the Fund's longstanding utilization of treasury future hedges to
prudently manage interest rate risk. As the year progressed and the Fed
continued to unveil the ever-broadening scope of its market support, coupled
with legislative initiatives, risk assets staged a dramatic comeback that has
persisted into the close of the fiscal year. As such, valuations on both
Non-Agency RMBS and Agency MBS have improved, which helped the Fund to recover
from its NAV low which was posted on March 25, 2020. Since the NAV low, the Fund
has outperformed its 1-5 Year Treasury benchmark by nearly 200 bps.


                                                                          Page 5

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

MARKET OUTLOOK

The Fed has deployed emergency rate cuts, large scale QE, unprecedented lending
programs and has signaled it plans to be highly accommodative for some time to
come. We believe this will keep the front end of the yield curve anchored in
place in the near term, with any rate volatility centralized in the longer
maturity segments of the yield curve. We do expect consumer and overall economic
data to continue to recover, with the recovery likely to accelerate on the back
of any potential additional stimulus package, as well as any positive
developments in COVID-19 treatment and vaccines to combat the pandemic. On the
other side of that, a rapid acceleration of the pandemic, and corresponding
enhanced large-scale restrictions or lockdowns could be quite detrimental to our
growth forecast. Over the near term, we expect no rise in inflation, but given
the surge in the money supply and dollar weakness, we could see inflationary
pressure build over the medium term. We remain positive on MBS spread valuations
over the longer term and believe there is additional capacity for spread
tightening to occur. Lastly, while we do generally expect interest rate
volatility to remain somewhat muted due to ongoing fiscal and monetary programs
deployed to assist in fighting the virus, chiefly quantitative easing and the
potential for a yield curve control type program by the Fed, we are mindful that
volatility could spike around the U.S. elections in November 2020.

Given our outlook on the broader bond markets, we plan to continue to actively
manage the Fund versus the Index from a duration standpoint, especially after
the dramatic declines in Treasury yields to such uneconomic levels. To the
extent the curve sees a large bear steepening, likely due to inflation, supply
or volatility, we will look to take advantage of higher longer maturity yields.
Across the mortgage sector, prepayments remain extremely elevated due to low
interest rates and mortgage buybacks. As such, we continue to favor select, call
protected MBS interest only securities, loan balance specified pools, Agency
Commercial Mortgage-Backed Securities, locked out Collateralized Mortgage
Obligation structures and select TBA hedges. Our goal is simple. Lock in longer,
more certain mortgage cashflow in government guaranteed sectors, with little to
no credit loss risk, protecting for a strategic period the yield, income,
dividend and spread for the Fund's shareholders. Over time, we expect others
will need those same characteristics and those bonds will become dearer and
perform well. Going forward, we are extremely positive on the Fund's future
performance as its securities represent attractive value relative to the
corporate, generic mortgage and treasury sectors, in our view. We continue to
maintain exceptional liquidity within a difficult environment allowing us the
ability to take advantage of opportunities should they arise in Non-Agency RMBS
and Non-Agency Commercial Mortgage-Backed Securities.

FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (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, 2020.

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)   Zero coupon security.

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

(d)   Inverse floating rate security.

(e)   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.

      security has been determined to be illiquid by First Trust Advisors L.P.,
      the Fund's advisor (the "Advisor").

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

(h)   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 adopted 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, 2020,
      securities noted as such amounted to $337,110,138 or 5.3% of net assets.

(i)   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).

(j)   Step security. The coupon rate is determined based on the underlying
      investments. The coupon rate resets periodically.

(k)   Investment in an affiliated fund.

(l)   Rate shown reflects yield as of October 31, 2020.

(m)   Aggregate cost for federal income tax purposes is $6,570,558,787. As of
      October 31, 2020, the aggregate gross unrealized appreciation for all
      investments in which there was an excess of value over tax cost was
      $168,139,031 and the aggregate gross unrealized depreciation for all
      investments in which there was an excess of tax cost over value was
      $51,845,493. The net unrealized appreciation was $116,293,538. The amounts
      presented are inclusive of investments sold short and derivative
      contracts.

      which interest payments are based.

LIBOR - London Interbank Offered Rate

PO    - Principal-Only Security

STRIPS - Separate Trading of Registered Interest and Principal of Securities

      annualized for periods of less than a year and does not include securities
      received or delivered from processing creations or redemptions and in-kind
      transactions.

(d)   The portfolio turnover rate not including mortgage dollar rolls was 245%,
      246%, 117% and 97% for the years ended October 31, 2020, 2019, 2018 and

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine 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"). Unlike conventional mutual funds, the Fund
issues and redeems shares on a continuous basis, at net asset value ("NAV"),
only in large specified blocks consisting of 50,000 shares called a "Creation
Unit." Creation Units are generally issued and redeemed for cash and, in certain
circumstances, in-kind for securities in which the Fund invests, and only to and
from broker-dealers and large institutional investors that have entered into
participation agreements. Except when aggregated in Creation Units, the Fund's
shares are not redeemable securities.

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

A. PORTFOLIO VALUATION

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

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Advisor's Pricing Committee, in

                                OCTOBER 31, 2020

accordance with valuation procedures adopted by the Trust's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. The Fund's investments are valued as follows:

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

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

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

      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 principal market for such securities.

      Shares of open-end funds are valued at fair value which is 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 fair 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 fair 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 Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) 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


                                                                         Page 51

amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

            1)    the fundamental business data relating to the issuer;

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

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

            4)    the financial statements of the issuer;

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

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

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

            8)    the coupon payments;

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

           10)    the business prospects of the 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);

           11)    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

           12)    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, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

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.

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2020

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, 2020, the Fund had no when-issued or
delayed-delivery securities. At October 31, 2020, the Fund held $1,123,862,050
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
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.


                                                                         Page 53

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2020

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.

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 purchase 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, 2020 and for the fiscal year
then ended are as follows:

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.

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

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


                                                                         Page 55

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                                OCTOBER 31, 2020

The tax character of distributions paid during the fiscal years ended October
31, 2020 and 2019 was as follows:

Distributions paid from:                              2020             2019
Ordinary income.................................  $  87,387,315   $   69,256,766
Capital gains...................................             --        1,877,704
Return of capital...............................     19,702,687        4,340,158


As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:



Undistributed ordinary income...................  $ (10,921,500)
Accumulated capital and other gain (loss).......   (108,942,487)
Net unrealized appreciation (depreciation)......    116,293,538


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 2017,
2018, 2019, and 2020 remain open to federal and state audit. As of October 31,
2020, 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, 2020, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $108,942,487.

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, 2020, 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,
2020, the adjustments for the Fund were as follows:




                                ACCUMULATED
             ACCUMULATED        NET REALIZED
            NET INVESTMENT      GAIN (LOSS)
            INCOME (LOSS)      ON INVESTMENTS     PAID-IN CAPITAL
            --------------     --------------     ---------------
            $    3,910,958     $   (3,910,958)    $            --


M. EXPENSES

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

N. NEW ACCOUNTING PRONOUNCEMENT

On March 30, 2017, the FASB issued Accounting Standards Update ("ASU") 2017-08
"Premium Amortization on Purchased Callable Debt Securities", which amends the
amortization period for certain purchased callable debt securities held at a
premium by shortening such period to the earliest call date. The new guidance
requires an entity to amortize the premium on a callable debt security within
its scope to the earliest call date, unless the guidance for considering
estimated prepayments is applied. If the call option is not exercised at the
earliest call date, the yield is reset to the effective yield using the payment

terms of the security. If the security has more than one call date and the
premium was amortized to a call price greater than the next call price, any
excess of the amortized cost basis over the amount repayable at the next call
date will be amortized to that date. If there are no other call dates, any
excess of the amortized cost basis over the par amount will be amortized to
maturity. Discounts on purchased callable debt securities will continue to be
amortized to the security's maturity date. The ASU 2017-08 is effective for
public business entities for fiscal years, and interim periods within those
fiscal years, beginning after December 15, 2018. ASU 2017-08 was adopted for
these financial statements and did not have a material impact.

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

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

Additionally, the Lead Independent Trustee and the Chairmen 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
Chairmen will rotate every three years. The officers and "Interested" Trustee
receive no compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The cost of purchases of U.S. Government securities and non-U.S. Government
securities, excluding investments sold short and short-term investments, for the
fiscal year ended October 31, 2020, were $15,190,987,877 and $638,826,656,
respectively. The proceeds from sales and paydowns of U.S. Government securities

and Liabilities.

                 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Due to the nature of the Fund's investments, the
Fund's Creation Units are generally issued and redeemed for cash, although
Creation Units may be issued in-kind for securities in which the Fund invests in
limited circumstances. Authorized Participants purchasing Creation Units must
pay to BNYM, as transfer agent, a creation transaction fee (the "Creation
Transaction Fee") regardless of the number of Creation Units purchased in the
transaction. The Creation Transaction Fee may increase or decrease with changes
in the Fund's portfolio. The price for each Creation Unit will equal the daily
NAV per share 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 or stamp taxes. When Creation Units are issued for cash,
the Authorized Participant may also be assessed an amount to cover the cost of
purchasing portfolio securities, including 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 such securities.

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's

portfolio. When shares are redeemed for cash, the Authorized Participant may
also be assessed an amount to cover other costs, including 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
portfolio securities sold in connection with the redemption.

                              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, 2022.

                               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. OTHER MATTERS

By operation of law, LMBS now operates as a diversified open-end management
investment company as defined in Section 5(b) of the 1940 Act.

                             10. SUBSEQUENT EVENTS

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


                                                                         Page 59

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, 2020, 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, 2020, 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, 2020, 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
reasonable basis for our opinion.

We have served as the auditor of one or more First Trust investment companies
since 2001.

                            FEDERAL TAX INFORMATION

Distributions paid to foreign shareholders during the Fund's fiscal year ended
October 31, 2020 that were properly designated by the Fund as "interest-related
dividends" or "short-term capital gain dividends," may not be subject to federal
income tax provided that the income was earned directly by such foreign
shareholders.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2020, 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 large
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
not concentrated.

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.

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.

                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                               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, 2021 at a meeting held on June 8, 2020. 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
reasonable 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 May 11, 2020 and June 8, 2020, 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 fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May
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


                                                                         Page 63

                          OCTOBER 31, 2020 (UNAUDITED)

held prior to the June 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the
operations of the Advisor and the performance of the Fund since the onset of the
COVID-19 pandemic. 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 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 Mortgage Securities Team 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 Mortgage
Securities Team and noted the Board's prior meetings with members of the Team.
The Board considered the Advisor's statement that it applies the same oversight
model internally with its Mortgage Securities Team 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 May 11, 2020 meeting, described
to the Board the scope of its ongoing investment in additional infrastructure
and personnel 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 advisory 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 May 11, 2020
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 there were no other actively-managed ETFs
in the Expense Group, 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, 2019
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 underperformed the Performance Universe median for the one- and three-year
periods ended December 31, 2019 but outperformed the Performance Universe median
for the five-year period ended December 31, 2019. The Board also noted that the
Fund underperformed the benchmark index for the one-year period ended December
31, 2019 but outperformed the benchmark index for the three- and five-year
periods ended December 31, 2019. The Board noted the Advisor's discussion of the
Fund's performance at the May 11, 2020 meeting.

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                          OCTOBER 31, 2020 (UNAUDITED)

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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from
its relationship with the Fund. The Board considered that the Advisor had
identified as a fall-out 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 fall-out 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.

                           LIQUIDITY RISK MANAGEMENT

In accordance with Rule 22e-4 under the Investment Company Act of 1940, as
amended (the "1940 Act"), the Funds and each other fund in the First Trust Fund
Complex, other than the closed-end funds, have adopted and implemented a
liquidity risk management program (the "Program") reasonably designed to assess
and manage the funds' liquidity risk, i.e., the risk that a fund could not meet
requests to redeem shares issued by the fund without significant dilution of
remaining investors' interests in the fund. The Board of Trustees of the First
Trust Funds has appointed First Trust Advisors, L.P. (the "Advisor") as the
person designated to administer the Program, and in this capacity the Advisor
performs its duties primarily through the activities and efforts of the First
Trust Liquidity Committee (the "Liquidity Committee"). Pursuant to the Program,
the Liquidity Committee classifies the liquidity of each fund's portfolio
investments into one of the four liquidity categories specified by Rule 22e-4:
highly liquid investments, moderately liquid investments, less liquid
investments and illiquid investments. The Liquidity Committee determines certain
of the inputs for this classification process, including reasonably anticipated
trade sizes and significant investor dilution thresholds. The Liquidity
Committee also determines and periodically reviews a highly liquid investment
minimum for certain funds, monitors the funds' holdings of assets classified as
illiquid investments to seek to ensure they do not exceed 15% of a fund's net
assets and establishes policies and procedures regarding redemptions in kind. At
the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4 and
the Program, the Advisor provided the Board with a written report prepared by
the Advisor that addressed the operation of the Program during the period from
June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Funds primarily hold assets that
are highly liquid investments, the Funds have not adopted a highly liquid
investment minimum.

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

                                  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


                                                                         Page 65

                          OCTOBER 31, 2020 (UNAUDITED)

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, 2019, the amount of remuneration paid (or to
be paid) by First Trust in respect of the Fund is $3,453,778. This figure is
comprised of $580,971 paid (or to be paid) in fixed compensation and $2,872,807
paid (or to be paid) in variable compensation. There were a total of 15
beneficiaries of the remuneration described above. Those amounts include
$687,434 paid (or to be paid) to senior management of First Trust and $2,766,344
paid (or to be paid) to other employees whose professional activities have a
material impact on the risk profiles of First Trust or the Fund (collectively,
"Code Staff").

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.

This report contains certain forward-looking statements within the meaning of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. Forward-looking statements include statements regarding the goals, beliefs, plans or current expectations of First Trust Advisors L.P. (“First Trust” or the “Advisor”) and/or SSI Investment Management LLC (“SSI” or the “Sub-Advisor”) and their respective representatives, taking into account the information currently available to them. Forward-looking statements include all statements that do not relate solely to current or historical fact. For example, forward-looking statements include the use of words such as “anticipate,” “estimate,” “intend,” “expect,” “believe,” “plan,” “may,” “should,” “would” or other words that convey uncertainty of future events or outcomes.
Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the series of First Trust Exchange-Traded Fund IV (the “Trust”) described in this report (First Trust SSI Strategic Convertible Securities ETF; hereinafter referred to as the “Fund”) to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

We undertake no obligation to publicly revise or update these forward-looking statements to reflect events and circumstances that arise after the date hereof.
Performance and Risk Disclosure
There is no assurance that the Fund will achieve its investment objective. 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 by 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.
The Advisor may also periodically provide additional information on Fund performance on the Fund’s web page at www.ftportfolios.com.
How to Read This Report
This report contains information that may help you evaluate your investment in the Fund. It includes details about the Fund and presents data and analysis that provide insight into the Fund’s performance and investment approach.
By reading the portfolio commentary by the portfolio management team of the Fund, you may obtain an understanding of how the market environment affected the Fund’s performance.

It is important to keep in mind that the opinions expressed by personnel of the Advisor and/or Sub-Advisor are just that: informed opinions. They should not be considered to be promises or advice.

Shareholder Letter
First Trust SSI Strategic Convertible Securities ETF (FCVT)
Annual Letter from the Chairman and CEO
October 31, 2020
Dear Shareholders,
First Trust is pleased to provide you with the annual report for the First Trust SSI Strategic Convertible Securities ETF (the “Fund”), which contains detailed information about the Fund for the twelve months ended October 31, 2020.
As I was collecting my thoughts for this annual roundup it occurred to me that my message this year should touch on the tone of the markets and the investing climate rather than belabor all the news and events that brought us to this juncture. We all know how tumultuous our lives have become over the past eight or so months. The phrase “shelter-at-home” says it all. I would rather talk about why I believe investors should be optimistic about where we could be headed.
Having said that, allow me to at least acknowledge the two elephants in the room: the coronavirus (“COVID-19”) and the election. In the first 12 days of November, we learned the following: that we likely have a new president-elect (Joe Biden), though it may not be official for some time because it is being contested by President Donald Trump and some of his loyal backers in the Republican Party citing voter fraud in certain states; that we still do not know which political party will have control of the Senate due to a couple of run-offs in Georgia to be held on January 5, 2021; and, that it looks as though we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either the end of 2020 or the start of 2021, though that too is not yet official. It could be a game-changer in the COVID-19 battle. And, we may gain access to additional vaccines as well. The key to getting the economy back to running on all cylinders is to fully reopen, and a vaccine is “what the doctor ordered.”
With respect to the tone of the markets and investment climate, to say that I am encouraged about what has transpired in 2020 would be an understatement. Despite the extraordinary challenges so far this year, the S&P 500® Index posted a total return of 2.77% over the first 10 months of 2020, this despite plunging 33.8% into bear market territory from February 19, 2020 through March 23, 2020, according to Bloomberg. As impressive as that feat is, the future looks even brighter. While Bloomberg’s consensus earnings growth rate estimate for the S&P 500® Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022 estimates were 21.74% and 16.95%, respectively. That is a strong take on the prospects for a rebound in Corporate America over the next 24 months. One of the tailwinds that is providing a good deal of support to the economy and markets is the decision by the Federal Reserve (the “Fed”) to keep interest rates artificially low for as long as need be to meet both its employment and inflation targets. By keeping rates lower for longer, the Fed is essentially inviting investors to assume more risk to generate higher returns. Brian Wesbury, Chief Economist at First Trust, believes that the Fed could need until 2024 to accomplish its goals. That is a lot of runway for investors to reposition their portfolios, if needed, and a very generous, and perhaps unprecedented, amount of guidance from the Fed, in our opinion. Those investors with cash on the sidelines earning next to nothing have options if they choose to act.
We are encouraged about the prospects for the economy and the markets, but investors should be prepared to weather some volatility until the COVID-19 pandemic is better contained. As always, we encourage investors to stay the course!
Thank you for giving First Trust the opportunity to play a role in your financial future. We value our relationship with you and will report on the Fund again in six months.
Sincerely,
James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

Total returns for the period since inception are calculated from the inception date of the Fund. “Average Annual Total Returns” represent the average annual change in value of an investment over the period indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.
The 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.

Commentary
Market Recap – For the 12-month period ended October 31, 2020:
Prior to the emergence of the coronavirus (“COVID-19”), U.S. gross domestic product was positive, the unemployment rate stood at multi-year lows, the S&P 500® Index was near its 52-week high and credit spreads were near 52-week lows, according to Bloomberg.
The COVID-19 pandemic exacted a terrible human toll and led to extreme challenges in all areas of society. Preventative measures led to a dramatic contraction in economic activity, but fiscal and monetary stimulus coupled with improved medical treatments and vaccine progress spurred recovery in the economy and capital markets.
As U.S. election politics took center stage, the markets grappled with bouts of additional volatility.
U.S. economic activity, which experienced an unprecedented drop and rebound, is expected to grow at 3.8% in 2021, according to Bloomberg.
Corporate earnings growth is expected to decline 18% in 2020 before rebounding 26% in 2021, according to Yardeni Research, Inc.
After spiking in March 2020 to levels not seen since 2008, credit spreads declined to pre-pandemic levels on Federal Reserve (the “Fed”) buying and economic recovery.
Ten-year Treasury yields fell by 81 basis points to 0.88% on low inflation and Fed buying.
Within the convertible universe, Consumer Discretionary, Health Care, and Technology generated significant gains, while Energy, Utilities, and Materials lagged.
Large cap and equity alternatives convertibles outperformed.
The convertible market remains healthy, in our view, evidenced by $102 billion in new issuance for the year, the strongest new issuance since the financial crisis.
Fund Performance
Convertible performance was driven by strong returns in growth equities and stable high yield markets for the 12-month period ended October 31, 2020. The Russell 1000® Growth Index advanced 29.22% and the Bloomberg Barclays High Yield Index rose 3.49% for the same period.
Fixed income posted positive returns with the Bloomberg Barclays US Aggregate Bond Index up 6.19% for the same period.
On a one-year trailing basis, as of October 31, 2020, the Fund generated a net gain of 29.1% based on net asset value. This exceeded the return of the ICE BofA All US Convertible Index (VXA0), which was 28.1%.

Annual Report
October 31, 2020 (Unaudited)
Technology and Energy made the largest contribution to portfolio returns on a relative basis. Sea Ltd. benefitted from strength in its mobile gaming e-commerce segments, driven in part by consumer demand during “stay-at-home” orders. Underweights in distressed energy credits such as Chesapeake Energy Corp. and Transocean Ltd. also aided relative performance.
Consumer Discretionary was the largest detractor on a relative basis due primarily to being underweight the convertibles of automaker, Tesla, Inc. and e-commerce retailer, Wayfair LLC. An underweight in the Financials sector also detracted from relative performance.
Investment Outlook
The outlook for the Fund is positive, as we believe many of the drivers contributing to the strong returns during the 12-month period ended October 31, 2020 remain in place.
The economy bottomed early in the second quarter and data has consistently exceeded expectations during the recovery.
The S&P 500® equity market returns are up 48% off the March lows. The Technology sector which makes up a significant portion of the convertible market, is up 58% during the 12-month period ended October 31, 2020.
Although markets have done well and economic activity is improving, the ongoing impact of COVID-19 remains difficult to quantify.
The Fed has indicated that highly accommodative policies will continue for an extended period, providing significant support to the economy and financial markets.
In the coming year, we believe convertibles are positioned to participate if the market continues higher due to their equity-like characteristics. Convertibles may also offer some downside protection if a more adverse environment develops, due to their bond-like feature of return of principal (par value) at maturity.

Understanding Your Fund Expenses
October 31, 2020 (Unaudited)
As a shareholder of the First Trust SSI Strategic Convertible Securities 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, 2020.
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) Expenses are equal to the annualized expense ratios as indicated in the table multiplied by the average account value over the period (May 1, 2020 through October 31, 2020), multiplied by 184/366 (to reflect the six-month period).

(b) This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(c) Zero coupon security.
(d) Stated maturity represents the mandatory conversion date.

First Trust SSI Strategic Convertible Securities ETF (FCVT)
October 31, 2020
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 nine funds that are offering shares. This report covers the First Trust SSI Strategic Convertible Securities ETF (the “Fund”), a diversified series of the Trust, which trades under the ticker “FCVT” on The Nasdaq Stock Market LLC (“Nasdaq”). Unlike conventional mutual funds, the Fund issues and redeems shares on a continuous basis, at net asset value (“NAV”), only in large specified blocks consisting of 50,000 shares called a “Creation Unit.” Creation Units are issued and redeemed for cash and, in certain circumstances, in-kind for securities in which the Fund invests. Except when aggregated in Creation Units, the Fund’s shares are not redeemable securities.
The Fund is an actively managed exchange-traded fund. The investment objective of the Fund is to seek total return. Under normal market conditions, the Fund seeks to achieve its investment objective by investing at least 80% of its net assets (including investment borrowings) in a portfolio of U.S. and non-U.S. convertible securities. There can be no assurances that the Fund will achieve its investment objective. The Fund may not be appropriate for all investors.
2. Significant Accounting Policies
The Fund is considered an investment company and follows accounting and reporting guidance under Financial Accounting Standards Board Accounting Standards Codification Topic 946, “Financial Services-Investment Companies.” The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of the financial statements. The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates.
A. Portfolio Valuation
The Fund’s NAV is determined daily as of the close of regular trading on the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund’s NAV is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses and dividends declared but unpaid), by the total number of shares outstanding.
The Fund’s investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent last sale or official closing prices from a national or foreign exchange (i.e., a regulated market) and are primarily obtained from third-party pricing services. Fair value prices represent any prices not considered market value prices and are either obtained from a third-party pricing service or are determined by the Pricing Committee of the Fund’s investment advisor, First Trust Advisors L.P. (“First Trust” or the “Advisor”), in accordance with valuation procedures adopted by the Trust’s Board of Trustees, and in accordance with provisions of the 1940 Act. Investments valued by the Advisor’s Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund’s investments are valued as follows:
Convertible preferred 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 principal market for such securities.
Convertible corporate bonds, notes and other debt securities are fair valued on the basis of valuations provided by dealers who make markets in such securities or by a third-party pricing service approved by the Trust’s Board of Trustees, which may use the following valuation inputs when available:
1) benchmark yields;
2) reported trades;
3) broker/dealer quotes;
4) issuer spreads;
5) benchmark securities;
6) bids and offers; and
7) reference data including market research publications.

Securities traded in an over-the-counter market are fair valued at the mean of their most recent bid and asked price, if available, and otherwise at their closing bid price.
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 Trust’s Board of Trustees or its delegate, the Advisor’s Pricing Committee, at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a third-party pricing service is unable to provide a market price; securities whose trading has been formally suspended; a security whose market or fair value price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of the Fund’s NAV or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the third-party pricing service, does not reflect the security’s fair value. As a general principle, the current fair value of a security would appear to be the amount which the owner might reasonably expect to receive for the security upon its current sale. When fair value prices are used, generally they will differ from market quotations or official closing prices on the applicable exchanges. A variety of factors may be considered in determining the fair value of such securities.
Fair valuation of a debt security will be based on the consideration of all available information, including, but not limited to, the following:
1) the fundamental business data relating to the issuer;
2) an evaluation of the forces which influence the market in which these securities are purchased and sold;
3) the type, size and cost of the security;
4) the financial statements of the issuer;
5) the credit quality and cash flow of the issuer, based on the sub-advisor’s or external analysis;
6) the information as to any transactions in or offers for the security;
7) the price and extent of public trading in similar securities (or equity securities) of the issuer/borrower, or comparable companies;
8) the coupon payments;
9) the quality, value and salability of collateral, if any, securing the security;
10) the business prospects of the issuer, including any ability to obtain money or resources from a parent or affiliate and an assessment of the issuer’s management;
11) the prospects for the issuer’s industry, and multiples (of earnings and/or cash flows) being paid for similar businesses in that industry; and
12) other relevant factors.
Fair valuation of an equity security will be based on the consideration of all available information, including, but not limited to, the following:
1) the type of security;
2) the size of the holding;
3) the initial cost of the security;
4) transactions in comparable securities;
5) price quotes from dealers and/or third-party pricing services;
6) relationships among various securities;
7) information obtained by contacting the issuer, analysts, or the appropriate stock exchange;

8) an analysis of the issuer’s financial statements; and
9) the existence of merger proposals or tender offers that might affect the value of the security.
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:
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.
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.
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, 2020, is included with the Fund’s Portfolio of Investments.
B. Securities Transactions and Investment Income
Securities transactions are recorded as of the trade date. Realized gains and losses from securities transactions are recorded on the identified cost basis. Dividend income is recorded on the ex-dividend date. Interest income is recorded daily on the accrual basis. Amortization of premiums and accretion of discounts are recorded using the effective interest method.
The Fund invests in convertible securities that are acquired at a price significantly above the principal value. Consequently, the amortization of premium may exceed the interest income earned on the securities.
C. Dividends and Distributions to Shareholders
Dividends from net investment income, if any, are declared and paid monthly by the Fund, or as the Board of Trustees may determine from time to time. Distributions of net realized capital gains earned by the Fund, if any, are distributed at least annually.
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 by the Fund during the fiscal years ended October 31, 2020 and 2019, was as follows:
Distributions paid from: 2020 2019
Ordinary income

$3,308,156 $2,995,341
Capital gains

Return of capital

As of October 31, 2020, the components of distributable earnings on a tax basis were as follows:
Undistributed ordinary income

$
Accumulated capital and other gain (loss)

2,284,319
Net unrealized appreciation (depreciation)

53,541,818

D. 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 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, 2020, for federal income tax purposes, the Fund had no capital loss carryforwards available to the extent provided by regulations to offset future capital gains.
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, 2020, the Fund had no net ordinary losses.
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. Taxable years ended 2017, 2018, 2019, and 2020 remain open to federal and state audit. As of October 31, 2020, 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.
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 and in-kind transactions. The results of operations and net assets were not affected by these adjustments. For the fiscal year ended October 31, 2020, the adjustments for the Fund were as follows:
Accumulated
Net Investment
Income (Loss)
  Accumulated
Net Realized
Gain (Loss)
on Investments
  Paid-in
Capital
$6,112,462   $(6,803,752)   $691,290
E. Expenses
Expenses, other than the investment advisory fee and other excluded expenses, are paid by the Advisor (See Note 3).
3. Investment Advisory Fee, Affiliated Transactions and Other Fee Arrangements
First Trust, the investment advisor to the Fund, is a limited partnership with one limited partner, Grace Partners of DuPage L.P., and one general partner, The Charger Corporation. The Charger Corporation is an Illinois corporation controlled by James A. Bowen, Chief Executive Officer of First Trust. First Trust is responsible for supervising 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.
The Fund and First Trust have retained SSI Investment Management LLC (“SSI” or the “Sub-Advisor”) to serve as its investment sub-advisor. In this capacity, SSI is responsible for the selection and on-going monitoring of the securities in the Fund’s investment portfolio. Pursuant to the Investment Management Agreement between the Trust and the Advisor, First Trust will supervise SSI and its management of the investment of the Fund’s assets and will pay SSI for its services as the Fund’s sub-advisor. First Trust will also be responsible for the Fund’s expenses, including the cost of transfer agency, custody, fund administration, legal, audit and other services, but excluding fee payments under the Investment Management Agreement, interest, taxes, acquired fund fees and expenses, brokerage commissions and other expenses connected with the execution of portfolio transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses. The Fund has agreed to pay First Trust an annual unitary management fee equal to 0.95% of its average daily net assets. SSI receives a sub-advisory fee from First Trust equal to 50% of any remaining monthly investment management fee paid to First Trust after the average Fund expenses accrued during the most recent twelve months are subtracted from the investment management fee in a given month. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $9,250, which is covered under the annual unitary management fee.

The Trust has multiple service agreements with Brown Brothers Harriman & Co. (“BBH”). Under the service agreements, BBH performs custodial, fund accounting, certain administrative services, and transfer agency services for the Fund. As custodian, BBH is responsible for custody of the Fund’s assets. As fund accountant and administrator, BBH is responsible for maintaining the books and records of the Fund’s securities and cash. As transfer agent, BBH is responsible for maintaining shareholder records for the Fund.
Each Trustee who is not an officer or employee of First Trust, any sub-advisor or any of their affiliates (“Independent Trustees”) is paid a fixed annual retainer that is allocated equally among each fund in the First Trust Fund Complex. Each Independent Trustee is also paid an annual per fund fee that varies based on whether the fund is a closed-end or other actively managed fund, a defined-outcome fund or an index fund.
Additionally, the Lead Independent Trustee and the Chairmen 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 Chairmen rotate every three years. The officers and “Interested” Trustee receive no compensation from the Trust for acting in such capacities.
4. Purchases and Sales of Securities
The cost of purchases and proceeds from sales of securities, excluding short-term investments and in-kind transactions, for the fiscal year ended October 31, 2020, were $253,484,871 and $255,203,654, respectively.
For the fiscal year ended October 31, 2020, the Fund had no in-kind transactions.
5. Creations, Redemptions and Transaction Fees
Shares are created and redeemed by the Fund only in Creation Unit size aggregations of 50,000 shares in transactions with broker-dealers or large institutional investors that have entered into a participation agreement (an “Authorized Participant”). Due to the nature of the Fund’s investments, the Fund’s Creation Units are generally issued and redeemed for cash, although Creation Units may be issued in-kind for securities in which the Fund invests in limited circumstances. Authorized Participants purchasing Creation Units must pay to BBH, as transfer agent, a creation transaction fee (the “Creation Transaction Fee”) regardless of the number of Creation Units purchased in the transaction. The Creation Transaction Fee may vary and is based on the composition of the securities included in the Fund’s portfolio and/or the countries in which the transactions are settled. The Creation Transaction Fee may increase or decrease with changes in the Fund’s portfolio. The price for each Creation Unit will equal the daily NAV per share 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 or stamp taxes. When Creation Units are issued for cash, the Authorized Participant may also be assessed an amount to cover the cost of purchasing portfolio securities, including 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 such securities.
Authorized Participants redeeming Creation Units must pay to BBH, as transfer agent, a standard redemption transaction fee (the “Redemption Transaction Fee”), regardless of the number of Creation Units redeemed in the transaction. The Redemption Transaction Fee may vary and is based on the composition of the securities included in the Fund’s portfolio and/or the countries in which the transactions are settled. The Redemption Transaction Fee may increase or decrease with changes in the Fund’s portfolio. When shares are redeemed for cash, the Authorized Participant may also be assessed an amount to cover other costs, including 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 portfolio securities sold in connection with the redemption.
6. Distribution Plan
The Board of Trustees adopted a Distribution and Service Plan pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Rule 12b-1 plan, the Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year to reimburse First Trust Portfolios L.P. (“FTP”), the distributor of the Fund, for amounts expended to finance activities primarily intended to result in the sale of Creation Units or to provide 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, 2022.

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 SSI Strategic Convertible Securities ETF (the “Fund”), a series of the First Trust Exchange-Traded Fund IV, including the portfolio of investments, as of October 31, 2020, 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 the years ended October 31, 2020, 2019, 2018, and 2017, and the period from November 3, 2015 (commencement of operations) through October 31, 2016, 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, 2020, 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 the years ended October 31, 2020, 2019, 2018, and 2017, and for the period from November 3, 2015 (commencement of operations) through October 31, 2016, 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, 2020, 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 reasonable basis for our opinion.

Dividends Received Deduction   Qualified Dividend Income
35.15%   35.15%
A portion of the ordinary dividends (including short-term capital gains) that the Fund paid to shareholders during the taxable year ended October 31, 2020, may be eligible for the Qualified Business Income (QBI) Deduction under the Internal Revenue Code of 1986, as amended, section 199A for the aggregate dividends the Fund received from the underlying Real Estate Investment Trusts (REITs) it invests in.
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 large 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 not concentrated.
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.
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 Constituent Risk. Certain funds may be a constituent of one or more indices. 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 significantly 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.
Index Provider Risk. To the extent a fund seeks to track an index, it is subject to Index Provider Risk. There is no assurance that the Index Provider will compile the Index accurately, or that the Index will be determined, maintained, constructed, reconstituted, rebalanced, composed, calculated or disseminated accurately. To correct any such error, the Index Provider may carry out an unscheduled rebalance or other modification of the Index constituents or weightings, which may increase the fund’s costs. The Index Provider does not provide any representation or warranty in relation to the quality, accuracy or completeness of data in the Index, and it does not guarantee that the Index will be calculated in accordance with its stated methodology. Losses or costs associated with any Index Provider errors generally will be borne by the fund and its shareholders.
Investment Companies Risk. To the extent a fund invests in the securities of other investment vehicles, the fund will incur additional fees and expenses that would not be present in a direct investment in those investment vehicles. Furthermore, the fund’s investment performance and risks are directly related to the investment performance and risks of the investment vehicles in which the fund invests.
LIBOR Risk. To the extent a fund invests in floating or variable rate obligations that use the London Interbank Offered Rate (“LIBOR”) as a reference interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom’s Financial Conduct Authority announced that LIBOR will cease to be available for use after 2021. 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. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses to the fund.

Management Risk. To the extent that a fund is actively managed, it is subject to management risk. In managing an actively-managed fund’s investment portfolio, the fund’s portfolio managers will apply investment techniques and risk analyses that may not have the desired result. There can be no guarantee that a fund will meet its investment objective.
Market Risk. Securities held by a fund, as well as shares of a fund itself, are subject to market fluctuations caused by factors such as general economic conditions, political events, regulatory or market developments, changes in interest rates and perceived trends in securities prices. Shares of a fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, spread of infectious diseases or other public health issues, recessions, or other events could have a significant negative impact on a fund and its investments. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. The outbreak of the respiratory disease designated as COVID-19 in December 2019 has caused significant volatility and declines in global financial markets, which have caused losses for investors. The COVID-19 pandemic may last for an extended period of time and will continue to impact the economy for the foreseeable future.
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; lack of liquidity; currency exchange rates; excessive taxation; government seizure of assets; 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.
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.

Advisory and Sub-Advisory Agreements
Board Considerations Regarding Approval of Continuation of Investment Management and Sub-Advisory Agreements
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 “Advisory Agreement”) with First Trust Advisors L.P. (the “Advisor”) on behalf of the First Trust SSI Strategic Convertible Securities ETF (the “Fund”). The Board approved the continuation of the Advisory Agreement for a one-year period ending June 30, 2021 at a meeting held on June 8, 2020. The Board determined that the continuation of the Advisory 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 reasonable 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 May 11, 2020 and June 8, 2020, 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 fall-out 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 May 11, 2020, prior to which the Independent Trustees and their counsel met separately to discuss the information provided by the Advisor. Following the May meeting, counsel to the Independent Trustees, on behalf of the Independent Trustees,

Additional Information (Continued)
First Trust SSI Strategic Convertible Securities ETF (FCVT)
October 31, 2020 (Unaudited)
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 8, 2020 meeting, as well as at the meeting held that day. The Board considered supplemental information provided by the Advisor on the operations of the Advisor and the performance of the Fund since the onset of the COVID-19 pandemic. 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 the Fund’s perspective. The Board determined that, given the totality of the information provided with respect to the Advisory Agreement, the Board had received sufficient information to renew the Advisory 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.
The Board noted that it had approved a new Investment Sub-Advisory Agreement (the “Sub-Advisory Agreement”) among the Fund, the Advisor and SSI Investment Management LLC (the “Sub-Advisor”) at a meeting held on March 11, 2019 for an initial two-year term and that shareholders of the Fund approved the Sub-Advisory Agreement at a meeting held on July 11, 2019. Accordingly, the Board did not consider the renewal of the Sub-Advisory Agreement at the June 8, 2020 meeting and will first consider its renewal at its June 2021 meeting.
In reviewing the Advisory Agreement, the Board considered the nature, extent and quality of the services provided by the Advisor under the Advisory Agreement. With respect to the Advisory 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, including the oversight of the Sub-Advisor, as well as the background and experience of the persons responsible for such services. The Board noted that the Advisor oversees the Sub-Advisor’s day-to-day management of the Fund’s investments, 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, the Sub-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 May 11, 2020 meeting, described to the Board the scope of its ongoing investment in additional infrastructure and personnel 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 Advisory Agreement have been and are expected to remain satisfactory.
The Board considered the unitary fee rate payable by the Fund under the Advisory 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 sub-advisory, transfer agency, custody, fund administration, legal, audit and other services and license fees, if any, but excluding the fee payment under the Advisory 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 advisory 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 May 11, 2020 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 there were no other actively-managed ETFs in the Expense Group, and different business models that may affect the pricing of services among ETF sponsors. The Board also noted that not all peer funds employ an advisor/sub-advisor management structure. 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 and Sub-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, 2019 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 underperformed the Performance Universe median and the benchmark index for the one- and three-year periods ended December 31, 2019.

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 (out of which the Sub-Advisor is compensated) 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 Advisory 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 its expenses will likely increase over the next twelve months as the Advisor continues to hire personnel and build infrastructure, including technology, to improve the services to the Fund. The Board noted that any reduction in fixed costs associated with the 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, 2019 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 fall-out benefits described by the Advisor that may be realized from its relationship with the Fund. The Board considered that the Advisor had identified as a fall-out 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. The Board also considered the Advisor’s compensation for fund reporting services provided to the Fund pursuant to a separate Fund Reporting Services Agreement, which is paid from the unitary fee. The Board concluded that the character and amount of potential fall-out 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 Advisory Agreement continue to be fair and reasonable and that the continuation of the Advisory Agreement is in the best interests of the Fund. No single factor was determinative in the Board’s analysis.
Liquidity Risk Management Program
In accordance with Rule 22e-4 under the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund and each other fund in the First Trust Fund Complex, other than the closed-end funds, have adopted and implemented a liquidity risk management program (the “Program”) reasonably designed to assess and manage the funds’ liquidity risk, i.e., the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors’ interests in the fund. The Board of Trustees of the First Trust Funds has appointed First Trust Advisors L.P. (the “Advisor”) as the person designated to administer the Program, and in this capacity the Advisor performs its duties primarily through the activities and efforts of the First Trust Liquidity Committee (the “Liquidity Committee”).
Pursuant to the Program, the Liquidity Committee classifies the liquidity of each fund’s portfolio investments into one of the four liquidity categories specified by Rule 22e-4: highly liquid investments, moderately liquid investments, less liquid investments and illiquid investments. The Liquidity Committee determines certain of the inputs for this classification process, including reasonably anticipated trade sizes and significant investor dilution thresholds. The Liquidity Committee also determines and periodically reviews a highly liquid investment minimum for certain funds, monitors the funds’ holdings of assets classified as illiquid investments to seek to ensure they do not exceed 15% of a fund’s net assets and establishes policies and procedures regarding redemptions in kind.
At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4 and the Program, the Advisor provided the Board with a written report prepared by the Advisor that addressed the operation of the Program during the period from June 1, 2019 (the initial compliance date for certain requirements of Rule 22e-4) through the Liquidity Committee’s annual meeting held on March 20, 2020 and assessed the Program’s adequacy and effectiveness of implementation during this period, including the operation of the highly liquid investment minimum for each fund that is required under the Program to have one, and any material changes to the Program. Note that because the Fund primarily holds assets that are highly liquid investments, the Fund has not adopted a highly liquid investment minimum.
As stated in the written report, during the review period, no fund breached the 15% limitation on illiquid investments, no fund with a highly liquid investment minimum breached that minimum and no fund filed a Form N-LIQUID. The Advisor concluded that each fund’s investment strategy is appropriate for an open-end fund; that the Program operated effectively in all material respects during the review period; and that the Program is reasonably designed to assess and manage the liquidity risk of each fund and to maintain compliance with Rule 22e-4.

as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and its representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
the series of First Trust Exchange-Traded Fund IV (the "Trust") described in

performance or achievements expressed or implied by the forward-looking

cautioned not to place undue reliance on these forward-looking statements, which
reflect the judgment of the Advisor and its representatives only as of the date

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objective. 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 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.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at www.ftportfolios.com.

SHAREHOLDER LETTER

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2020


Dear Shareholders:

First Trust is pleased to provide you with the annual report for the First Trust
Long Duration Opportunities ETF (the "Fund"), which contains detailed
information about the Fund for the twelve months ended October 31, 2020.

As I was collecting my thoughts for this annual roundup it occurred to me that
my message this year should touch on the tone of the markets and the investing
climate rather than belabor all the news and events that brought us to this
juncture. We all know how tumultuous our lives have become over the past eight
or so months. The phrase "shelter-at-home" says it all. I would rather talk
about why I believe investors should be optimistic about where we could be
headed.

Having said that, allow me to at least acknowledge the two elephants in the
room: the coronavirus ("COVID-19") and the election. In the first 12 days of
November, we learned the following: that we likely have a new president-elect
(Joe Biden), though it may not be official for some time because it is being
contested by President Donald Trump and some of his loyal backers in the
Republican Party citing voter fraud in certain states; that we still do not know
which political party will have control of the Senate due to a couple of
run-offs in Georgia to be held on January 5, 2021; and, that it looks as though
we may be fortunate enough to have an FDA-approved COVID-19 vaccine by either
the end of 2020 or the start of 2021, though that too is not yet official. It
could be a game-changer in the COVID-19 battle. And, we may gain access to
additional vaccines as well. The key to getting the economy back to running on
all cylinders is to fully reopen, and a vaccine is "what the doctor ordered."

With respect to the tone of the markets and investment climate, to say that I am
encouraged about what has transpired in 2020 would be an understatement. Despite
the extraordinary challenges so far this year, the S&P 500(R) Index posted a
total return of 2.77% over the first 10 months of 2020, this despite plunging
33.8% into bear market territory from February 19, 2020 through March 23, 2020,
according to Bloomberg. As impressive as that feat is, the future looks even
brighter. While Bloomberg's consensus earnings growth rate estimate for the S&P
500(R) Index for 2020 was -16.51%, as of November 13, 2020, its 2021 and 2022
estimates were 21.74% and 16.95%, respectively. That is a strong take on the
prospects for a rebound in Corporate America over the next 24 months. One of the
tailwinds that is providing a good deal of support to the economy and markets is
the decision by the Federal Reserve (the "Fed") to keep interest rates
artificially low for as long as need be to meet both its employment and
inflation targets. By keeping rates lower for longer, the Fed is essentially
inviting investors to assume more risk to generate higher returns. Brian
Wesbury, Chief Economist at First Trust, believes that the Fed could need until
2024 to accomplish its goals. That is a lot of runway for investors to
reposition their portfolios, if needed, and a very generous, and perhaps
unprecedented, amount of guidance from the Fed, in our opinion. Those investors
with cash on the sidelines earning next to nothing have options if they choose
to act.

We are encouraged about the prospects for the economy and the markets, but
investors should be prepared to weather some volatility until the COVID-19
pandemic is better contained. As always, we encourage investors to stay the
course!

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

Sincerely,

/s/ James A. Bowen

Total returns for the periods 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 a 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.

First Trust Advisors L.P. ("First Trust" or the "Advisor") is the investment

"LGOV"). First Trust is responsible for the selection and ongoing monitoring of
the securities in the Fund's portfolio and certain other services necessary for
the management of the portfolio.

                                   COMMENTARY

The Fund's primary investment objective is to generate current income with a
focus on preservation of capital. Under normal market conditions, the Fund will
invest at least 80% of its net assets (including investment borrowings) in a
portfolio of investment-grade debt securities issued or guaranteed by the U.S.
government, its agencies or government-sponsored entities, including
publicly-issued U.S. Treasury securities and mortgage-related securities.

MARKET RECAP

The 12-month period ended October 31, 2020 began relatively calmly, being driven
primarily by policy decisions related to the trade war. The onset of the
coronavirus ("COVID-19") pandemic triggered an unprecedented liquidity crisis
across global markets, with its effects rippling through the domestic and global
economies and causing profound changes in both bond and equity market
fundamentals, risk factors and valuations. Due to the nature of this pandemic,
the reversal in monetary policy driven by the trade war was put into overdrive.
In response, the Federal Reserve (the "Fed") began a new phase of seemingly
limitless quantitative easing, and reinstated programs that were last relied
upon during the Great Recession of 2008. It also began to roll out new programs,
expanding the range of covered asset classes, providing a backstop to the
significant dislocations and severe illiquidity that occurred. The Fed further
aided markets with emergency rate cuts totaling 150 basis points ("bps") in
March 2020 and setting the lower bound of the Fed Funds rate at 0%. The Fed was
not alone in providing aid, as Congress stepped in with a large stimulus package
to help Americans weather COVID-19 and its effects. Treasury issuance as a
result has soared to buoy government spending, however, with the aid of
quantitative easing ("QE") programs and a continued demand for safe haven
assets, Treasury yields plunged to record lows. For example, over the last year,
the 2-Year Treasury yield has declined precipitously by -137 bps to close on
October 31, 2020 at 15 bps, while the 10-Year Treasury fell -82 bps to close the
year at 87.4 bps, with the curve bull steepening. The COVID-19 panic did not
discriminate, affecting nearly every aspect of the broader spread markets,
including Agency Mortgage-Backed Securities ("MBS"), which initially saw large
spread widening moves as Agency MBS spreads widened dramatically from the low
40s Treasury Option-Adjusted Spread ("OAS"), to a wide of 136 OAS. Agency MBS
spreads tightened to close the fiscal year at 64 OAS, as the impact of Fed
programs and legislative support helped improve liquidity and greatly improved
market participants risk appetite.

PERFORMANCE ANALYSIS

For the 12-month period ended October 31, 2020, the Fund returned 7.46% on a net
asset value ("NAV") basis, net of fees. Since the Fund's inception on January
22, 2019, the Fund has returned 22.59% on a cumulative NAV basis, net of fees.

During 12-month period ended October 31, 2020, the ICE BofA 5+ Year US Treasury
Index (the "Index") returned 10.73%. Since the Fund's inception on January 22,
2019, the Index has returned 25.36% on a cumulative basis.

During the 12-month period ended October 31, 2020, the Fund underperformed the
Index by -327 bps, net of fees. The Fund is structured to own a significant
percentage of the fund in Agency MBS securities, whereas the benchmark is a pure
treasury and agency index. Agency MBS experienced substantial widening during
the severe illiquidity that gripped the fixed income markets during the early
stages of the COVID-19 pandemic unfolding in America. As markets digested the
rapid pace of lockdowns, uncertainties on future economic health, and the Fed's
rapidly evolving market support, Treasury yields plunged in an outright flight
to quality. The negative convexity associated with mortgage securities coupled
with spread widening was also detrimental to the Fund in terms of keeping up
with the violent Treasury market rally. As the year progressed and the Fed
continued to unveil the ever-broadening scope of its market support, coupled
with legislative initiatives, risk assets staged a dramatic comeback that has
persisted into the close of the fiscal year. As such, valuations on Agency MBS
have improved, which helped the fund to recover from the illiquid markets

                                 ANNUAL REPORT
                          OCTOBER 31, 2020 (UNAUDITED)

exhibited in March 2020. Since March 25, 2020, the Fund has outperformed its
5+year treasury benchmark in excess of 200 bps. A benefit to performance was
attributable to pricing performance of select odd lot Agency MBS positions at
the time of purchase. The Fund's portfolio managers reasonably expect that such
investments in odd lot positions could continue to impact the Fund's performance
to the extent the Fund continues to grow. Additionally, given the significant
rally in treasury yields in the first quarter of 2020, followed by a modest
selloff in treasury yields later in the year, the Fund's usage of derivatives to
manage overall interest rate risk, volatility, and convexity was mildly
detrimental to the Fund's performance over the 12-month period ended October 31,
2020.

MARKET OUTLOOK

The Fed has deployed emergency rate cuts, large scale QE, unprecedented lending
programs and has signaled it plans to be highly accommodative for some time to
come. We believe this will keep the front end of the yield curve anchored in
place in the near term, with any rate volatility centralized in the longer
maturity segments of the yield curve. We do expect consumer and overall economic
data to continue to recover, with the recovery likely to accelerate on the back
of any potential additional stimulus package, as well as any positive
developments in COVID-19 treatment and vaccines to combat the pandemic. On the
other side of that, a rapid acceleration of the pandemic, and corresponding
enhanced large-scale restrictions or lockdowns could be quite detrimental to our
growth forecast. Over the near term, we expect no rise in inflation, but given
the surge in the money supply and dollar weakness, we could see inflationary
pressure build over the medium term. We remain positive on MBS spread valuations
over the longer term and believe there is additional capacity for spread
tightening to occur. Lastly, while we do generally expect interest rate
volatility to remain somewhat muted due to ongoing fiscal and monetary programs
deployed to assist in fighting the virus, chiefly quantitative easing and the
potential for a yield curve control type program by the Fed, we are mindful that
volatility could spike around the U.S. elections in November 2020.

Given our outlook on the broader bond markets, we plan to continue to actively
manage the Fund versus the Index from a duration standpoint, especially after
the dramatic declines in Treasury yields to such uneconomic levels. To the
extent the curve sees a large bear steepening, likely due to inflation, supply
or volatility, we will look to take advantage of higher, longer maturity yields.
Across the mortgage sector, prepayments remain extremely elevated due to low
interest rates and mortgage buybacks. As such, we continue to favor select, call
protected locked out collateralized mortgage obligation ("CMO") structures,
Agency Multifamily Commercial Mortgage-Backed Securities, and select TBA
securities. Our goal is simple. Lock in longer, more certain mortgage cashflow
in government guaranteed sectors, with little to no credit loss risk, protecting
for a strategic period the yield, income, dividend and spread for the Fund's
shareholders. Over time, we expect others will need those same characteristics
and those bonds will become dearer and outperform. We continue to maintain
exceptional liquidity within a difficult environment allowing us the ability to
take advantage of opportunities.

FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)

UNDERSTANDING YOUR FUND EXPENSES
OCTOBER 31, 2020 (UNAUDITED)

As a shareholder of First Trust Long 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, 2020.

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)   Annualized expense ratio and expenses paid during the six-month period do
      not include fees and expenses of the underlying funds in which the Fund
      invests.

(b)   Expenses are equal to the annualized expense ratio as indicated in the
      table multiplied by the average account value over the period (May 1, 2020
      through October 31, 2020), multiplied by 184/366 (to reflect the six-month
      period).

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                                OCTOBER 31, 2020

                                1. ORGANIZATION

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

The Trust currently consists of nine funds that are offering shares. This report
covers the First Trust Long Duration Opportunities ETF (the "Fund"), a
non-diversified series of the Trust, which trades under the ticker "LGOV" on the
NYSE Arca, Inc. ("NYSE Arca"). Unlike conventional mutual funds, the Fund issues
and redeems shares on a continuous basis, at net asset value ("NAV"), only in
large specified blocks consisting of 50,000 shares called a "Creation Unit."
Creation Units are generally issued and redeemed for cash and, in certain
circumstances, in-kind for securities in which the Fund invests, and only to and
from broker-dealers and large institutional investors that have entered into
participation agreements. Except when aggregated in Creation Units, the Fund's
shares are not redeemable securities.

The Fund is an actively managed exchange-traded fund ("ETF"). The Fund's primary
investment objective is to generate current income with a focus on preservation
of capital. The Fund seeks to achieve its investment objectives by investing,
under normal market conditions, at least 80% of its net assets (including
investment borrowings) in a portfolio of investment-grade debt securities issued
or guaranteed by the U.S. government, its agencies or government-sponsored
entities, including publicly-issued U.S. Treasury securities and
mortgage-related securities. The Fund may also invest in exchange-traded funds
("ETFs") that principally invest in such securities. The Fund's investments in
mortgage-related securities may include investments in fixed or adjustable-rate
securities structured as "pass-through" securities and collateralized mortgage
obligations, including residential and commercial mortgage-backed securities,
stripped mortgage-backed securities and real estate mortgage investment
conduits. The Fund will invest in mortgage-related securities issued or
guaranteed by the U.S. government, its agencies (such as Ginnie Mae), and U.S.
government-sponsored entities (such as Fannie Mae and Freddie Mac). The Fund may
purchase government-sponsored mortgage-related securities in "to-be-announced"
transactions ("TBA Transactions"), including 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"). In addition to its investment in
securities issued or guaranteed by the U.S. government, its agencies and
government-sponsored entities, the Fund may invest up to 20% of its net assets
in other types of debt securities, including privately-issued, non-agency
sponsored asset-backed and mortgage-related securities, futures contracts,
options, swap agreements, cash and cash equivalents, and ETFs that invest
principally in fixed income securities. Further, the Fund may enter into short
sales as part of its overall portfolio management strategy, 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. Although the Fund intends to invest
primarily in investment grade securities, the Fund may invest up to 20% of its
net assets 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 a weighted average effective duration of eight or more
years.

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value. Market
value prices represent last sale or official closing prices from a national or
foreign exchange (i.e., a regulated market) and are primarily obtained from
third-party pricing services. Fair value prices represent any prices not
considered market value prices and are either obtained from a third-party
pricing service or are determined by the Advisor's Pricing Committee, in


                                                                         Page 15

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                                OCTOBER 31, 2020

accordance with valuation procedures adopted by the Trust's Board of Trustees,
and in accordance with provisions of the 1940 Act. Investments valued by the
Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to
the Portfolio of Investments. The Fund's investments are valued as follows:

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

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

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

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding The Nasdaq Stock Market LLC ("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 principal market for such securities.

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

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                                OCTOBER 31, 2020

            1)    the fundamental business data relating to the issuer;

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

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

            4)    the financial statements of the issuer;

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

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

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

            8)    the coupon payments;

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

           10)    the business prospects of the 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);

           11)    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

           12)    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, 2020, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

In July 2017, the Financial Conduct Authority ("FCA") announced that it will no
longer persuade or compel banks to submit rates for the calculations of the
London Interbank Offered Rates ("LIBOR") after 2021. Further, the FCA has
subsequently stated, as recently as March 2020, that the central assumption
continues to be that firms should not rely on LIBOR being published after the
end of 2021.

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.

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


                                                                         Page 17

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

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                                OCTOBER 31, 2020

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, 2020, the Fund had no when-issued,
delayed-delivery securities. At October 31, 2020, the Fund held $2,058,594 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 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 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

In the normal course of pursuing its investment objectives, the Fund may invest
up to 20% of its net assets in derivative instruments in connection with hedging
strategies. 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 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

               FIRST TRUST LONG DURATION OPPORTUNITIES ETF (LGOV)
                                OCTOBER 31, 2020

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.

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)


                                                                         Page 19

substantially similar (same type, coupon and maturity) securities on a future
date. Mortgage dollar rolls are recorded as separate purchase and sale 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. 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.

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

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

The tax character of distributions paid during the fiscal years ended October
31, 2020 and 2019 was as follows:



Distributions paid from:                                2020            2019
Ordinary income.................................   $      478,522   $    183,881
Capital gains...................................               --             --
Return of capital...............................               --             --


As of October 31, 2020, the components of distributable earnings on a tax basis
for the Fund were as follows:



Undistributed ordinary income...................   $      571,152
Accumulated capital and other gain (loss).......               --
Net unrealized appreciation (depreciation)......          769,941


K. INCOME TAXES

The Fund intends 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 and
2020 remain open to federal and state audit. As of October 31, 2020, 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, 2020, the
Fund had no non-expiring capital loss carryforwards for federal income tax
purposes.

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, 2020, 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,
2020, the adjustments for the Fund were as follows:

L. EXPENSES

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

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

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

Pursuant to the Investment Management Agreement between the Trust and 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.

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

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

Additionally, the Lead Independent Trustee and the Chairmen 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
Chairmen will rotate every three years. The officers and "Interested" Trustee
receive no compensation from the Trust for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

The cost of purchases of U.S. Government securities and non-U.S. Government
securities, excluding short-term investments, for the fiscal year ended October
31, 2020, were $28,789,638 and $156,582, respectively. The proceeds from sales
and paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the fiscal year ended October 31, 2020,
were $18,830,940 and $41,606, respectively. The cost of purchases to cover
investments sold short and the proceeds of investments sold short were
$1,026,094 and $1,026,094, respectively.

For the fiscal year ended October 31, 2020, the Fund had no in-kind
transactions.


                                                                         Page 21

                 6. CREATIONS, REDEMPTIONS AND TRANSACTION FEES

Shares are created and redeemed by the Fund only in Creation Unit size
aggregations of 50,000 shares in transactions with broker dealers or large
institutional investors that have entered into a participation agreement (an
"Authorized Participant"). Due to the nature of the Fund's investments, the
Fund's Creation Units are generally issued and redeemed for cash, although
Creation Units may be issued in-kind for securities in which the Fund invests in
limited circumstances. Authorized Participants purchasing Creation Units must
pay to BNYM, as transfer agent, a creation transaction fee (the "Creation
Transaction Fee") regardless of the number of Creation Units purchased in the
transaction. The Creation Transaction Fee may increase or decrease with changes
in the Fund's portfolio. The price for each Creation Unit will equal the daily
NAV per share 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 or stamp taxes. When Creation Units are issued for cash,
the Authorized Participant may also be assessed an amount to cover the cost of
purchasing portfolio securities, including 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 such securities.

                                OCTOBER 31, 2020

Authorized Participants redeeming Creation Units must pay to BNYM, as transfer
agent, a standard redemption transaction fee (the "Redemption Transaction Fee"),
regardless of the number of Creation Units redeemed in the transaction. The
Redemption Transaction Fee may increase or decrease with changes in the Fund's
portfolio. When shares are redeemed for cash, the Authorized Participant may
also be assessed an amount to cover other costs, including 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
portfolio securities sold in connection with the redemption.

                              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, 2022.

                               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
were no subsequent events, requiring recognition or disclosure in the financial
statements that have not already been disclosed.


                                                                         Page 23

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 Long Duration Opportunities ETF (the "Fund"), a series of the First Trust
Exchange-Traded Fund IV, including the portfolio of investments, as of October
31, 2020, the related statement of operations for the year then ended, and the
changes in net assets and the financial highlights for the year then ended and
for the period from January 22, 2019 (commencement of operations) through
October 31, 2019, 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, 2020, and the results of
its operations for the year then ended, and changes in its net assets and the
financial highlights for the year then ended and for the period from January 22,
2019 (commencement of operations) through October 31, 2019, 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 audit. 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 audit 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 audit 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 audit 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 audit
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, 2020, by correspondence with
the custodian and brokers; when replies were not received from and brokers, we
performed other auditing procedures. We believe that our audit provides a
reasonable basis for our opinion.

We have served as the auditor of one or more First Trust investment companies
since 2001.

                            FEDERAL TAX INFORMATION

Distributions paid to foreign shareholders during the Fund's fiscal year ended
October 31, 2020 that were properly designated by the Fund as "interest-related
dividends" or "short-term capital gain dividends," may not be subject to federal
income tax provided that the income was earned directly by such foreign
shareholders.

Of the ordinary income (including short-term capital gain) distributions made by
the Fund during the fiscal year ended October 31, 2020, 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 large
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
not concentrated.

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.

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.


                                                                         Page 25

                          OCTOBER 31, 2020 (UNAUDITED)

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 CONSTITUENT RISK. Certain funds may be a constituent of one or more
indices. 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
significantly 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.

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

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

LIBOR RISK. To the extent a fund invests in floating or variable rate
obligations that use the London Interbank Offered Rate ("LIBOR") as a reference
interest rate, it is subject to LIBOR Risk. In 2017, the United Kingdom's
Financial Conduct Authority announced that LIBOR will cease to be available for
use after 2021. 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. Any such effects of the transition
away from LIBOR, as well as other unforeseen effects, 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.

                          OCTOBER 31, 2020 (UNAUDITED)

MARKET RISK. Securities held by a fund, as well as shares of a fund itself, are
subject to market fluctuations caused by factors such as general economic
conditions, political events, regulatory or market developments, changes in
interest rates and perceived trends in securities prices. Shares of a fund could
decline in value or underperform other investments as a result of the risk of
loss associated with these market fluctuations. In addition, local, regional or
global events such as war, acts of terrorism, spread of infectious diseases or
other public health issues, recessions, or other events could have a significant
negative impact on a fund and its investments. Such events may affect certain
geographic regions, countries, sectors and industries more significantly than
others. The outbreak of the respiratory disease designated as COVID-19 in
December 2019 has caused significant volatility and declines in global financial
markets, which have caused losses for investors. The COVID-19 pandemic may last
for an extended period of time and will continue to impact the economy for the
foreseeable future.

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; lack
of liquidity; currency exchange rates; excessive taxation; government seizure of
assets; 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.

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.

                               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 Long Duration Opportunities ETF
(the "Fund"). The Board approved the continuation of the Agreement for a
one-year period ending June 30, 2021 at a meeting held on June 8, 2020. 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 reasonable 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 May 11, 2020 and June 8, 2020, 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; 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 fall-out 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 May
11, 2020, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor. Following the May
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 8, 2020 meeting, as well as at the meeting held that day.
The Board considered supplemental information provided by the Advisor on the


                                                                         Page 27

operations of the Advisor and the performance of the Fund since the onset of the
COVID-19 pandemic. 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 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 Mortgage Securities Team 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 Mortgage
Securities Team and noted the Board's prior meetings with members of the Team.
The Board considered the Advisor's statement that it applies the same oversight
model internally with its Mortgage Securities Team 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 objective,
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 May 11, 2020 meeting, described
to the Board the scope of its ongoing investment in additional infrastructure
and personnel 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 objective, 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, acquired fund fees and expenses, if any,
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 advisory 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 May 11, 2020
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 there were no other actively-managed ETFs
in the Expense Group, 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. Because the Fund commenced
operations on January 22, 2019 and therefore has a limited performance history,
comparative performance information for the Fund was not considered.

On the basis of all the information provided on the unitary fee for 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 its expenses will
likely increase over the next twelve months as the Advisor continues to hire
personnel and build infrastructure, including technology, to improve the
services to the Fund. The Board noted that any reduction in fixed costs
associated with the management of the Fund would benefit the Advisor, but that

                          OCTOBER 31, 2020 (UNAUDITED)

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 period from inception through December 31, 2019 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 twelve
months ended December 31, 2019. 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 fall-out benefits described by the Advisor that
may be realized from its relationship with the Fund. The Board considered that
the Advisor had identified as a fall-out 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 fall-out 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.

                       LIQUIDITY RISK MANAGEMENT PROGRAM

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

Pursuant to the Program, the Liquidity Committee classifies the liquidity of
each fund's portfolio investments into one of the four liquidity categories
specified by Rule 22e-4: highly liquid investments, moderately liquid
investments, less liquid investments and illiquid investments. The Liquidity
Committee determines certain of the inputs for this classification process,
including reasonably anticipated trade sizes and significant investor dilution
thresholds. The Liquidity Committee also determines and periodically reviews a
highly liquid investment minimum for certain funds, monitors the funds' holdings
of assets classified as illiquid investments to seek to ensure they do not
exceed 15% of a fund's net assets and establishes policies and procedures
regarding redemptions in kind.

At the May 11, 2020 meeting of the Board of Trustees, as required by Rule 22e-4
and the Program, the Advisor provided the Board with a written report prepared
by the Advisor that addressed the operation of the Program during the period
from June 1, 2019 (the initial compliance date for certain requirements of Rule
22e-4) through the Liquidity Committee's annual meeting held on March 20, 2020
and assessed the Program's adequacy and effectiveness of implementation during
this period, including the operation of the highly liquid investment minimum for
each fund that is required under the Program to have one, and any material
changes to the Program. Note that because the Fund primarily holds assets that
are highly liquid investments, the Fund has not adopted a highly liquid
investment minimum.

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

(e)(1) Disclose the audit committee’s pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

 

Pursuant to its charter and its Audit and Non-Audit Services Pre-Approval Policy, the Audit Committee (the “Committee”) is responsible for the pre-approval of all audit services and permitted non-audit services (including the fees and terms thereof) to be performed for the registrant by its independent auditors. The Chairman of the Committee is authorized to give such pre-approvals on behalf of the Committee up to $25,000 and report any such pre-approval to the full Committee.

 

The Committee is also responsible for the pre-approval of the independent auditor’s engagements for non-audit services with the registrant’s adviser (not including a sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant, subject to the de minimis exceptions for non-audit services described in Rule 2-01 of Regulation S-X. If the independent auditor has provided non-audit services to the registrant’s adviser (other than any sub-adviser whose role is primarily portfolio management and is sub-contracted with or overseen by another investment adviser) and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to its policies, the Committee will consider whether the provision of such non-audit services is compatible with the auditor’s independence.

 

(e)(2) The percentage of services described in each of paragraphs (b) through (d) for the registrant and the registrant’s investment adviser and distributor of this Item that were approved by the audit committee pursuant to the pre-approval exceptions included in paragraph (c)(7)(i)(C) or paragraph(C)(7)(ii) of Rule 2-01 of Regulation S-X are as follows:

 

Registrant:    Adviser and Distributor:

 

(b) 0%         (b) 0%

 

(c) 0%         (c) 0%

 

(d) 0%         (d) 0%

 

(f) The percentage of hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees was less than fifty percent.

 

(g) The aggregate non-audit fees billed by the registrant’s accountant for services rendered to the registrant, and rendered to the registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for the fiscal year ended October 31, 2019 were $169,630 for the registrant, $28,500 for the registrant’s investment adviser and $34,400 for the registrant’s distributor; and for the fiscal year ended October 31, 2020 were $199,634 for the registrant, $70,370 for the registrant’s investment adviser and $99,830 for the registrant’s distributor.

 

(h) The registrant’s audit committee of its Board of Trustees has determined that the provision of non-audit services that were rendered to the registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.

SENIOR FINANCIAL OFFICER
CODE OF CONDUCT

I. INTRODUCTION

This code of conduct is being adopted by the investment companies advised by First Trust Advisors L.P., from time to time, (the "Funds"). The reputation and integrity of the Funds are valuable assets that are vital to the Funds' success. Each officer of the Funds, and officers and employees of the investment adviser to the Funds who work on Fund matters, including each of the Funds' senior financial officers ("SFOs"), is responsible for conducting each Fund's business in a manner that demonstrates a commitment to the highest standards of integrity. SFOs include the Principal Executive Officer (who is the President), the Controller (who is the principal accounting officer), and the Treasurer (who is the principal financial officer), and any person who performs a similar function.

The Funds, First Trust Advisors L.P. and First Trust Portfolios have adopted Codes of Ethics under Rule 17j-1 under the Investment Company Act of 1940 (the "Rule 17j-1 Code"). These Codes of Ethics are designed to prevent certain conflicts of interest that may arise when officers, employees, or directors of the Funds and the foregoing entities know about present or future Fund transactions and/or have the power to influence those transactions, and engage in transactions with respect to those same securities in their personal account(s) or otherwise take advantage of their position and knowledge with respect to those securities. In an effort to prevent these conflicts and in accordance with Rule 17j-1, the Funds adopted their Rule 17j-1 Code to prohibit transactions and conduct that create conflicts of interest, and to establish compliance procedures.

The Sarbanes-Oxley Act of 2002 was designed to address corporate malfeasance and to help assure investors that the companies in which they invest are accurately and completely disclosing financial information. Under Section 406 of the Act, all public companies (including the Funds) must either have a code of ethics for their SFOs, or disclose why they do not. The Act was intended to prevent future situations (such as occurred in well-reported situations involving such companies as Enron and WorldCom) where a company creates an environment in which employees are afraid to express their opinions or to question unethical and potentially illegal business practices.

The Funds have chosen to adopt a senior financial officer Code of Conduct to encourage their SFOs, and other Fund officers and employees of First Trust Advisors or First Trust Portfolios to act ethically and to question potentially unethical or illegal practices, and to strive to ensure that the Funds' financial disclosures are complete, accurate, and understandable.


II. PURPOSES OF THIS CODE OF CONDUCT

The purposes of this Code are:

A. To promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

B. To promote full, fair, accurate, timely, and understandable disclosure in reports and documents that the Funds file with, or submits to, the SEC and in other public communications the Funds make;

C. To promote compliance with applicable governmental laws, rules and regulations;

D. To encourage the prompt internal reporting to an appropriate person of violations of the Code; and

E. To establish accountability for adherence to the Code.

III. QUESTIONS ABOUT THIS CODE

The Funds' Boards of Trustees have designated W. Scott Jardine or other appropriate officer designated by the President of the respective Funds to be the Compliance Coordinator for the implementation and administration of the Code.

IV. HANDLING OF FINANCIAL INFORMATION

The Funds have adopted guidelines under which its SFOs perform their duties. However, the Funds expect that all officers or employees of the adviser or distributor who participate in the preparation of any part of any Fund's financial statements follow these guidelines with respect to each Fund:

A. Act with honesty and integrity and avoid violations of this Code, including actual or apparent conflicts of interest with the Fund in personal and professional relationships.

B. Disclose to the Fund's Compliance Coordinator any material transaction or relationship that reasonably could be expected to give rise to any violations of the Code, including actual or apparent conflicts of interest with the Fund. You should disclose these transactions or relationships whether you are involved or have only observed the transaction or relationship. If it is not possible to disclose the matter to the Compliance Coordinator, it should be disclosed to the Fund's Principal Financial Officer or Principal Executive Officer.


C. Provide information to the Fund's other officers and appropriate employees of service providers (adviser, administrator, outside auditor, outside counsel, custodian, etc.) that is accurate, complete, objective, relevant, timely, and understandable.

D. Endeavor to ensure full, fair, timely, accurate, and understandable disclosure in the Fund's periodic reports.

E. Comply with the federal securities laws and other applicable laws and rules, such as the Internal Revenue Code.

F. Act in good faith, responsibly, and with due care, competence and diligence, without misrepresenting material facts or allowing your independent judgment to be subordinated.

G. Respect the confidentiality of information acquired in the course of your work except when you have Fund approval to disclose it or where disclosure is otherwise legally mandated. You may not use confidential information acquired in the course of your work for personal advantage.

H. Share and maintain skills important and relevant to the Fund's needs.

I. Proactively promote ethical behavior among peers in your work environment.

J. Responsibly use and control all assets and resources employed or entrusted to you.

K. Record or participate in the recording of entries in the Fund's books and records that are accurate to the best of your knowledge.

V. WAIVERS OF THIS CODE

SFOs and other parties subject to this Code may request a waiver of a provision of this Code (or certain provisions of the Fund's Rule 17j-1 Code) by submitting their request in writing to the Compliance Coordinator for appropriate review. An executive officer of the Fund or the Audit Committee will decide whether to grant a waiver. All waivers of this Code must be disclosed to the Fund's shareholders to the extent required by SEC rules. A good faith interpretation of the provisions of this Code, however, shall not constitute a waiver.

VI. ANNUAL CERTIFICATION

Each SFO will be asked to certify on an annual basis that he/she is in full compliance with the Code and any related policy statements.


VII. REPORTING SUSPECTED VIOLATIONS

A. SFOs or other officers of the Funds or employees of the First Trust group who work on Fund matters who observe, learn of, or, in good faith, suspect a violation of the Code must immediately report the violation to the Compliance Coordinator, another member of the Funds' or First Trust's senior management, or to the Audit Committee of the Fund Board. An example of a possible Code violation is the preparation and filing of financial disclosure that omits material facts, or that is accurate but is written in a way that obscures its meaning.

B. Because service providers such as an administrator, outside accounting firm, and custodian provide much of the work relating to the Funds' financial statements, you should be alert for actions by service providers that may be illegal, or that could be viewed as dishonest or unethical conduct. You should report these actions to the Compliance Coordinator even if you know, or think, that the service provider has its own code of ethics for its SFOs or employees.

C. SFOs or other officers or employees who report violations or suspected violations in good faith will not be subject to retaliation of any kind. Reported violations will be investigated and addressed promptly and will be treated confidentially to the extent possible.

VIII. VIOLATIONS OF THE CODE

A. Dishonest, unethical or illegal conduct will constitute a violation of this Code, regardless of whether this Code specifically refers to that particular conduct. A violation of this Code may result in disciplinary action, up to and including termination of employment. A variety of laws apply to the Funds and their operations, including the Securities Act of 1933, the Investment Company Act of 1940, state laws relating to duties owed by Fund directors and officers, and criminal laws. The federal securities laws generally prohibit the Funds from making material misstatements in its prospectus and other documents filed with the SEC, or from omitting to state a material fact. These material misstatements and omissions include financial statements that are misleading or omit materials facts.

B. Examples of criminal violations of the law include stealing, embezzling, misapplying corporate or bank funds, making a payment for an expressed purpose on a Fund's behalf to an individual who intends to use it for a different purpose; or making payments, whether corporate or personal, of cash or other items of value that are intended to influence the judgment or actions of political candidates, government officials or businesses in connection with any of the Funds' activities. The Funds must and will report all suspected criminal violations to the appropriate authorities for possible prosecution, and will investigate, address and report, as appropriate, non-criminal violations.
