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 North American Energy Infrastructure 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

                        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
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
http://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 http://www.ftportfolios.com.

                            HOW TO READ THIS REPORT

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

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016

Dear Shareholders:

Thank you for your investment in First Trust North American Energy
Infrastructure Fund (the "Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices, and second, the tapering that began in 2014 by the Federal Reserve
(the "Fed") did not stop growth in the U.S. economy. Finally, the
long-anticipated rate hike by the Fed in December had little effect on the money
supply, and the stock market was not shocked by the hike. Early in 2016, many
investors were concerned that the volatility we saw in the market in 2015 would
continue, and it did. From December 31, 2015 through February 11, 2016, the S&P
500(R) Index declined by 10.27%. Since then, the market has made a steady
comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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 NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)

The investment objective of the First Trust North American Energy Infrastructure
Fund (the "Fund") is to seek total return. The Fund pursues its objective by
investing at least 80% of its net assets under normal market conditions (plus
the amount of any borrowing for investment purposes) in equity securities of
companies 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, Canadian
Income Equities, pipeline companies, utilities and other companies that derive
at least 50% 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 be
generally concentrated in Energy Infrastructure Companies. Under normal market
conditions, the Fund will invest at least 80% of its net assets (plus the amount
of any borrowing for investment purposes) 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.

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


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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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.

-----------------------------
(1)   The Blended Benchmark consists of the following two indices: 50% of the
      Philadelphia Stock Exchange Utility 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.

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

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
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period June 21, 2012 (commencement
of trading) through April 30, 2016. Shareholders may pay more than NAV when they
buy Fund shares and receive less than NAV when they sell those shares because
shares are bought and sold at current market price. Data presented represents
past performance and cannot be used to predict future results.

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (UNAUDITED)

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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.

      1, 2015 through April 30, 2016), multiplied by 182/366 (to reflect the

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                           APRIL 30, 2016 (UNAUDITED)


                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust North American Energy Infrastructure Fund (the
"Fund"), which trades under the ticker "EMLP" 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 issued
and redeemed principally in-kind for securities in which the Fund invests or for
cash or, in certain circumstances, a combination of both. 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. The Fund invests in energy infrastructure
companies which principally include publicly-traded master limited partnerships
and limited liability companies taxed as partnerships ("MLPs"), MLP affiliates,
Canadian Income Equities, pipeline companies, utilities, and other companies
that derive at least 50% 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").

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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. 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
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 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:

      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.

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                           APRIL 30, 2016 (UNAUDITED)

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 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 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 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 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 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 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.


                                                                         Page 13

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                           APRIL 30, 2016 (UNAUDITED)

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, 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, if any, is
recorded on the accrual basis.

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.

C. 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
shown in "Net change in unrealized appreciation (depreciation) on investments"
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 and are shown in "Net realized
gain (loss) on foreign currency transactions" on the Statement 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
Statement of Operations.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income of the 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 the Fund, if any, are distributed
at least annually.

Distributions from net investment income and realized capital gains are
determined in accordance with 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 year ended October 31,
2015 was as follows:

Distributions paid from:

Ordinary income.................................      $   36,418,951
Capital gain....................................                  --
Return of capital...............................                  --

As of October 31, 2015, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income...................      $           --
Accumulated capital and other gain (loss).......         (20,930,851)
Net unrealized appreciation (depreciation)......         (94,526,075)

                           APRIL 30, 2016 (UNAUDITED)

E. INCOME TAXES

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

The Fund 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, 2015, the
Fund had non-expiring capital loss carryforwards available for federal income
tax purposes of $20,930,851.

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, 2015, 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. The taxable years ended 2012,
2013, 2014 and 2015 remain open to federal and state audit. As of April 30,
2016, 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.

F. EXPENSES

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

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

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the 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 Energy Income Partners, LLC ("EIP" or the
"Sub-Advisor"), an affiliate of First Trust, to serve as its investment
sub-advisor. In this capacity, EIP 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 EIP and its management of the investment of the Fund's assets and
will pay EIP 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, brokerage
commissions and other expenses connected with the execution of portfolio
transactions, distribution and service fees pursuant to a 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. EIP
receives a sub-advisory fee from First Trust equal to 45% 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 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
the Fund. As custodian, BNYM is responsible for custody of the Fund's assets. As
fund accountant and administrator, BNYM is responsible for maintaining the books
and records of the Fund's securities and cash. As transfer agent, BNYM is
responsible for maintaining shareholder records for the Fund. BNYM is a
subsidiary of The Bank of New York Mellon Corporation, a financial holding
company.


                                                                         Page 15

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                           APRIL 30, 2016 (UNAUDITED)

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. Each Independent Trustee is also paid an
annual per fund fee that varies based on whether the fund is a closed-end or
actively managed 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.
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 six months ended April 30, 2016, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
were $204,901,923 and $203,142,462 respectively.

For the six months ended April 30, 2016, the cost of in-kind purchases and
proceeds from in-kind sales were $211,110,053 and $58,412,405, respectively.

                 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"). In order to purchase Creation Units of the 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 is based on the
composition of the securities included in the Fund's portfolio and the countries
in which the transactions are settled. The Creation Transaction Fee is currently
$500. 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 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 the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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.

                              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

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER THE FUND'S INVESTMENT
OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV.

The following summarizes some of the risks that should be considered for the
Fund.

CONCENTRATION RISK. A fund concentrated in a single industry or sector is likely
to present more risks than a fund that is broadly diversified over several
industries or sectors. Compared to the broad market, an individual industry or
sector may be more strongly affected by changes in the economic climate, broad
market shifts, moves in a particular dominant stock, or regulatory changes.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the
underlying shares in their primary trading market. Any distributions paid to the
holders of depositary receipts are usually subject to a fee charged by the
depositary. Holders of depositary receipts may have limited voting rights, and
investment restrictions in certain countries may adversely impact the value of
depositary receipts because such restrictions may limit the ability to convert
the equity shares into depositary receipts and vice versa. Such restrictions may
cause the equity shares of the underlying issuer to trade at a discount or
premium to the market price of the depositary receipts.

EQUITY SECURITIES RISK. Because the Fund invests in equity securities, the value
of the Fund's shares will fluctuate with changes in the value of these 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 the capital rises and borrowing costs increase.

SMALLER COMPANIES RISK. The Fund invests in small and/or mid capitalization
companies. Such companies may be more vulnerable to adverse general market or
economic developments, and their securities may be less liquid and may
experience greater price volatility than larger, more established companies as a
result of several factors, including limited trading volumes, products or
financial resources, management inexperience and less publicly available
information. Accordingly, such companies are generally subject to greater market
risk than larger, more established companies.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund, Shares of the Fund or securities in general may fall in value. Shares are
subject to market fluctuations caused by such factors as economic, political,
regulatory or market developments, changes in interest rates and perceived
trends in securities prices. Overall securities values could decline generally
or could underperform other investments.

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

          FIRST TRUST NORTH AMERICAN ENERGY INFRASTRUCTURE FUND (EMLP)
                           APRIL 30, 2016 (UNAUDITED)

NON-DIVERSIFICATION RISK. Because the Fund is non-diversified, it may invest a
relatively high percentage of its assets in a limited number of issuers. As a
result, the Fund may be more susceptible to a single adverse economic or
regulatory occurrence affecting one or more of these issuers, experience
increased volatility and be highly concentrated in certain issues.

ENERGY INFRASTRUCTURE COMPANIES RISK. The Fund invests in Energy Infrastructure
Companies and is subject to certain risks inherent in investing in these types
of securities. Energy Infrastructure Companies may be directly affected by
energy commodity prices, especially those Energy Infrastructure Companies which
own the underlying energy commodity. A decrease in the production or
availability of natural gas, natural gas liquids ("NGLs"), crude oil, coal or
other energy commodities or a decrease in the volume of such commodities
available for transportation, processing, storage or distribution may adversely
impact the financial performance of Energy Infrastructure Companies. Energy
Infrastructure Companies are subject to significant federal, state and local
government regulation in virtually every aspect of their operations, including
how facilities are constructed, maintained and operated, environmental and
safety controls, and the prices they may charge for products and services.
Various governmental authorities have the power to enforce compliance with these
regulations and the permits issued under them and violators are subject to
administrative, civil and criminal penalties, including civil fines, injunctions
or both. Stricter laws, regulations or enforcement policies could be enacted in
the future which would likely increase compliance costs and may adversely affect
the financial performance of Energy Infrastructure Companies. Natural disasters,
such as hurricanes in the Gulf of Mexico, also may impact Energy Infrastructure
Companies.

Certain Energy Infrastructure Companies are subject to the imposition of rate
caps, increased competition due to deregulation, the difficulty in obtaining an
adequate return on invested capital or in financing large construction projects,
the limitations on operations and increased costs and delays attributable to
environmental considerations, and the capital market's ability to absorb utility
debt. In addition, taxes, government regulation, international politics, price
and supply fluctuations, volatile interest rates and energy conservation may
cause difficulties for these companies. Such issuers have been experiencing
certain of these problems to varying degrees.

MLP RISK. An investment in MLP units involves risks which differ from an
investment in common stock of a corporation. Holders of MLP units have limited
control and voting rights on matters affecting the partnership. In addition,
there are certain tax risks associated with an investment in MLP units and
conflicts of interest exist between common unit holders and the general partner,
including those arising from incentive distribution payments. In addition, there
is the risk that a MLP could be, contrary to its intention, taxed as a
corporation, resulting in decreased returns from such MLP.

GEOGRAPHIC RISK. The Fund invests primarily in securities of companies
headquartered or incorporated in the United States and Canada. An investment in
a particular geographic region may be particularly susceptible to changes in the
political, diplomatic and economic conditions of that region or any new
regulatory requirements of the region. Accordingly, an investment in the Fund
may be more volatile than an investment diversified across several geographic
regions.

NON-U.S. SECURITIES. The Fund invests in securities of non-U.S. issuers,
including non-U.S. dollar-denominated securities traded in Canada or other
foreign countries and U.S. dollar-denominated securities of non-U.S. issuers
traded in the United States. Such 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; excessive taxation; government seizure of assets;
different legal or accounting standards; and less government supervision and
regulation of exchanges in foreign countries. These risks may be heightened for
securities of companies located in, or with significant operations in, emerging
market countries.

CURRENCY RISK. Because the Fund's NAV is determined on the basis of U.S. dollars
and the Fund invests in foreign securities, you may lose money if the local
currency of a foreign market depreciates against the U.S. dollar, even if the
local currency value of the Fund's holdings goes up.

INTEREST RATE RISK. Rising interest rates could adversely impact the financial
performance of MLPs, MLP-related entities and energy companies. Rising interest
rates may increase an MLP's, MLP-related entity's or energy company's cost of
capital, which would increase operating costs and may reduce an MLP's,
MLP-related entity's or energy company's ability to execute acquisitions or
expansion projects in a cost-effective manner. Rising interest rates may also
impact the price of MLP units, MLP-related entity securities and energy company
shares as the yields on alternative investments increase.

MANAGEMENT RISK. The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, Energy
Income Partners will apply investment techniques and risk analyses that may not
have the desired result. There can be no guarantee that the Fund will meet its
investment objective.

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

                        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
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.

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

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016


Dear Shareholders:

Thank you for your investment in First Trust Senior Loan Fund (the "Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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 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. The Fund pursues its objectives by investing at least
80% of its net assets (plus the amount of any borrowing for investment purposes)
under normal market conditions in a diversified portfolio of first lien senior
floating rate loan interests ("Senior Loans"). 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"). A Senior Loan is considered senior
to all other unsecured claims against the borrower, senior to or equal with all
other secured claims; this means that in the event of a bankruptcy, the Senior
Loan, together with other first lien claims, is entitled to be the first to be
repaid out of proceeds of the assets securing the loans, before other existing
unsecured claims or interests receive repayment. However, in bankruptcy
proceedings, there may be other claims, such as taxes or additional advances
that take precedence.

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 an
average interest rate 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), (2) warrants and
equity securities issued by a borrower or its affiliates, and/or (3) securities
of other investment companies.

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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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.

(1)   The ratings are by Standard & Poor's Ratings 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
      rating of BBB- or higher. The credit ratings shown relate to the
      creditworthiness of the issuers of the underlying securities in the Fund,
      and not to the Fund or its shares. Credit ratings are subject to change.

Performance figures assume reinvestment of all distributions and do not reflect
the deduction of taxes that a shareholder would pay on Fund distributions or the
redemption or sale of Fund shares. An index is a statistical composite that
tracks a specified financial market or sector. Unlike the Fund, the 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
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period May 2, 2013 (commencement of
trading) through April 30, 2016. Shareholders may pay more than NAV when they
buy Fund shares and receive less than NAV when they sell those shares because
shares are bought and sold at current market price. Data presented represents
past performance and cannot be used to predict future results.

FIRST TRUST SENIOR LOAN FUND (FTSL)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (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 fees, if any, and other Fund
expenses. This Example is intended to help you understand your ongoing costs of
investing in the Fund and to compare these costs with the ongoing costs of
investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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 London Inter-Bank Offered Rate
      ("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. The interest rate
      shown reflects the rate in effect at April 30, 2016. When a range of rates
      is disclosed, the Fund holds more than one contract within the same
      tranche at varying rates.

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

(d)   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 April 30, 2016, securities noted as such amounted to $619,293
      or 0.1% of net assets.

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

(f)   This issuer is in default but interest is still being accrued by the Fund
      and paid by the issuer.

FIRST TRUST SENIOR LOAN FUND (FTSL)

PORTFOLIO OF INVESTMENTS (CONTINUED)
APRIL 30, 2016 (UNAUDITED)


(g)   On December 21, 2015, Millennium Health, LLC completed a Bankruptcy Plan
      of Reorganization. As part of the Bankruptcy Plan of Reorganization, the
      holders of Millennium Laboratories LLC, Tranche B Term Loan received a
      portion of a new term loan and a pro rata share of the newly issued common
      equity shares in New Millennium Holdco, Inc., the new company. Each lender
      was also issued a beneficial interest in the Corporate Claim Trust
      entitling it, as holder of such beneficial interest, to receive Corporate
      Claim Trust Distributions when and if net cash proceeds from the pursuit
      of Retained Corporate Causes of Action are available to make such a
      distribution. In addition, each lender was issued a beneficial interest in
      the Lender Claim Trust entitling it, as holder of such beneficial
      interest, to receive Lender Claim Trust Distributions when and if net cash
      proceeds from the pursuit of Retained Lender Causes of Action are
      available to make such a distribution.

(h)   Delayed Draw Loan (See Note 2C - Unfunded Loan Commitments in the Notes to
      Financial Statements).

(i)   Represents commitment fee rate on Unfunded Loan Commitment.

(j)   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 April 30, 2016,
      securities noted as such amounted to $10,709,273 or 2.4% of net assets.

(k)   These notes are Payment-in-Kind ("PIK") Notes whereby the issuer may, at
      its option, elect to pay interest on the notes (1) entirely in cash or (2)
      entirely in PIK Interest. Interest paid in cash will accrue at the rate of
      7.000% per annum ("Cash Interest Rate") and PIK Interest will accrue on
      the Notes at a rate per annum equal to the Cash Interest Rate plus 75
      basis points. For the six months ended April 30, 2016, this security paid
      all of its interest in cash.

(l)   Non-income producing security.

(m)   Interest rate shown reflects yield as of April 30, 2016.

(n)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2016, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $2,235,483 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $8,265,860.

FIRST TRUST SENIOR LOAN FUND (FTSL)

PORTFOLIO OF INVESTMENTS (CONTINUED)
APRIL 30, 2016 (UNAUDITED)

Level 3 Senior Floating-Rate Loan Interests that are fair valued by the
Advisor's Pricing Committee are footnoted in the Portfolio of Investments. Level
3 Senior Floating-Rate Loan Interests are valued based on either third-party
pricing service prices obtained from dealer runs and indicative sheets from
brokers or are valued using broker quotes. The values are based on unobservable
and non-quantitative inputs. The Trust's Board of Trustees has adopted valuation
procedures that are utilized by the Advisor's Pricing Committee to oversee the
day-to-day valuation of the Fund's investments. The Advisor's Pricing Committee,
through the Fund's fund accounting agent, monitors the daily pricing via
tolerance checks and stale and unchanged price reviews. The Advisor's Pricing
Committee also reviews monthly back testing of pricing service prices by
comparing sales prices of the Fund's investments to prior day pricing service
prices. Additionally, the Advisor's Pricing Committee reviews periodic
information from the Fund's third-party pricing service that compares secondary
market trade prices to their daily valuations.

The following table presents the activity of the Fund's investments measured at
fair value on a recurring basis using significant unobservable inputs (Level 3)
for the period presented:

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust Senior Loan Fund (the "Fund"), 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. The Fund
pursues its objectives by investing at least 80% of its net assets (plus the
amount of any borrowing for investment purposes) under normal market conditions
in a diversified portfolio of first lien senior floating rate loan interests
("Senior Loans")(1). A Senior Loan is an advanced 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. 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, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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:

      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

-----------------------------
(1)   The terms "security" and "securities" used throughout the Notes to
      Financial Statements include Senior Loans.


                                                                         Page 23

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

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

      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 an independent 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.

      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 60
      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 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 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 (or
            equity securities) of the borrower/issuer, or comparable companies;

       8)   the coupon payments;

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

       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 April 30, 2016, 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.
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.

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 commitments discussed below) as of April 30, 2016.

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. The Fund had unfunded delayed drawn loan commitments of
$95,186 as of April 30, 2016.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund. The Fund distributes its net realized capital gains, if any, to
shareholders 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.


                                                                         Page 25

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

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

The tax character of distributions paid during the fiscal year ended October 31,
2015 was as follows:

            Distributions        Distributions        Distributions
              paid from            paid from            paid from
              Ordinary              Capital             Return of
               Income                Gains               Capital
            -------------        -------------        -------------
            $  10,638,104        $          --        $          --

As of October 31, 2015, the components of distributable earnings on a tax basis
for the Fund were as follows:

                                  Accumulated              Net
            Undistributed         Capital and          Unrealized
              Ordinary               Other            Appreciation
               Income            Gains (Loss)         (Depreciation)
            -------------        -------------        -------------
            $     397,650        $    (496,979)       $  (9,548,485)

E. INCOME TAXES

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

The Fund 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, 2015, the
Fund had $496,979 of non-expiring capital loss carryforwards that may be carried
forward indefinitely.

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, 2015, 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. The taxable years ended 2013,
2014 and 2015 remain open to federal and state audit. As of April 30, 2016,
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.

F. EXPENSES

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

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

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

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

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, acquired
fund fees and expenses, brokerage commissions and other expenses connected with
the execution of portfolio transactions, distribution and service fees pursuant
to a 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 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. 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, 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.
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 six months ended April 30, 2016, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
were $228,451,112 and $154,427,674, respectively.

For the six months ended April 30, 2016, there were no in-kind transactions.

                                 5. BORROWINGS

The Trust, on behalf of the Fund, along with First Trust Exchange-Traded Fund
III and First Trust Series Fund entered into a $140 million Credit Agreement
with The Bank of Nova Scotia ("Scotia") as administrative agent for a group of
lenders. 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. Prior to March 9, 2016, the commitment amount was $80 million and the
commitment fee was 0.15%. First Trust allocates the commitment 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 six months ended April 30, 2016.

                 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 is based on the composition of the securities included
in the Fund's portfolio and the countries in which the transactions are settled.
The Creation Transaction Fee is currently $500. 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


                                                                         Page 27

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 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 the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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, 2017.

                               8. INDEMNIFICATION

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

                              9. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through
the date the financial statements were issued, and has determined that there was
the following subsequent event:

On May 19, 2016, the Fund declared a distribution of $0.15 per share to
shareholders of record on May 24, 2016, payable May 31, 2016.

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER THE FUND'S INVESTMENT
OBJECTIVE, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV.

The following summarizes some of the risks that should be considered for the
Fund.

BANK LOAN RISK: An investment in Senior Loans subjects the Fund to credit risk,
which is heightened for Senior Loans in which the Fund invests because companies
that issue such loans tend to be highly leveraged and thus are more susceptible
to the risks of interest deferral, default and/or bankruptcy. Senior Loans are
usually rated below investment grade but may also be unrated. An economic
downturn would generally lead to a higher non-payment rate, and a Senior Loan
may lose significant market value before a default occurs. Moreover, any
specific collateral used to secure a Senior Loan may decline in value or become
illiquid, which would adversely affect the loan's value. Unlike the securities
markets, there is no central clearinghouse for Senior Loan trades, and the
Senior Loan market has not established enforceable settlement standards or
remedies for failure to settle. Therefore, portfolio transactions in Senior
Loans may have uncertain settlement time periods. Senior Loans are subject to a
number of risks described elsewhere in this prospectus, including liquidity risk
and the risk of investing in below investment grade fixed-income instruments.

CALL RISK. If an issuer calls higher-yielding securities held by the Fund,
performance could be adversely impacted.

CASH TRANSACTION RISK: The Fund currently intends to effect a significant
portion of creations and redemptions for cash, rather than in-kind securities.
As a result, an investment in the Fund may be less tax-efficient than an
investment in an exchange-traded fund that effects its creations and redemptions
for in-kind securities. Because the Fund principally effects redemptions for
cash, it may be required to sell portfolio securities in order to obtain the
cash needed to distribute redemption proceeds. A sale of shares may result in
capital gains or losses, and may also result in higher brokerage costs.

CONVERTIBLE BONDS RISK. The market values of convertible bonds tend to decline
as interest rates increase and, conversely, to increase as interest rates
decline. A convertible bond's market value also tends to reflect the market
price of the common stock of the issuing company.

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. Credit risk may be heightened
for the Fund because it may invest a substantial portion of its net assets in
high yield or "junk" debt; such securities, while generally offering higher
yields than investment-grade debt with similar maturities, involve greater
risks, including the possibility of dividend or interest deferral, default or
bankruptcy, and are regarded as predominantly speculative with respect to the
issuer's capacity to pay dividends or interest and repay principal. Credit risk
is heightened for loans in which the Fund invests because companies that issue
such loans tend to be highly leveraged and thus are more susceptible to the
risks of interest deferral, default and/or bankruptcy.


                                                                         Page 29

                           APRIL 30, 2016 (UNAUDITED)

CURRENCY RISK. Because the Fund's net asset value is determined on the basis of
U.S. dollars and the Fund invests in foreign securities, you may lose money if
the local currency of a foreign market depreciates against the U.S. dollar, even
if the local currency value of the Fund's holdings goes up. The Fund intends to
hedge its non-U.S. dollar holdings.

HIGH YIELD SECURITIES RISK: High yield securities, or "junk" bonds, are subject
to greater market fluctuations and risk of loss than securities with higher
ratings, and therefore, may be highly speculative. These securities are issued
by companies that may have limited operating history, narrowly focused
operations, and/or other impediments to the timely payment of periodic interest
and principal at maturity. If the economy slows down or dips into recession, the
issuers of high yield securities may not have sufficient resources to continue
making timely payment of periodic interest and principal at maturity. The market
for high yield securities is smaller and less liquid than that for investment
grade securities. High yield securities are generally not listed on a national
securities exchange but trade in the over-the-counter markets. Due to the
smaller, less liquid market for high yield securities, the bid-offer spread on
such securities is generally greater than it is for investment grade securities
and the purchase or sale of such securities may take longer to complete.

ILLIQUID SECURITIES RISK. Illiquid securities involve the risk that the
securities will not be able to be sold at the time desired by the Fund or at
prices approximately the value at which the Fund is carrying the securities on
its books.

INCOME RISK: If interest rates fall, the income from the Fund's portfolio will
likely decline because the Fund holds floating rate debt that will adjust lower
with falling interest rates. For loans, interest rates typically reset
periodically.

INTEREST RATE RISK: Interest rate risk is the risk that the value of the debt
securities in the Fund will decline because of rising market interest rates.
Interest rate risk is generally lower for shorter-term investments and higher
for longer-term investments. Duration is a common measure of interest rate risk,
which measures a bond's expected life on a present value basis, taking into
account the bond's yield, interest payments and final maturity. Duration is a
reasonably accurate measure of a bond's price sensitivity to changes in interest
rates. The longer the duration of a bond, the greater the bond's price
sensitivity is to changes in interest rates.

LIQUIDITY RISK: The Fund invests a substantial portion of its assets in
lower-quality debt issued by companies that are highly leveraged. Lower-quality
debt tends to be less liquid than higher-quality debt. Moreover, smaller debt
issues tend to be less liquid than larger debt issues. If the economy
experiences a sudden downturn, or if the debt markets for such companies become
distressed, the Fund may have particular difficulty selling its assets in
sufficient amounts, at reasonable prices and in a sufficiently timely manner to
raise the cash necessary to meet any potentially heavy redemption requests by
Fund shareholders.

MANAGEMENT RISK: The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, the
Advisor will apply investment techniques and risk analyses that may not have the
desired result. There can be no guarantee that the Fund will meet its investment
objectives.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in
securities prices. Shares of the Fund could decline in value generally or could
underperform other investments.

NON-DIVERSIFICATION RISK: The Fund is classified as "non-diversified" under the
Investment Company Act of 1940, as amended. As a result, the Fund is only
limited as to the percentage of its assets that may be invested in the
securities of any one issuer by the diversification requirements imposed by the
Internal Revenue Code of 1986, as amended. The Fund may invest a relatively high
percentage of its assets in a limited number of issuers. As a result, the Fund
may be more susceptible to a single adverse economic or regulatory occurrence
affecting one or more of these issuers, experience increased volatility and be
highly concentrated in certain issuers.

NON-U.S. SECURITIES RISK: 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.

                      FIRST TRUST SENIOR LOAN FUND (FTSL)
                           APRIL 30, 2016 (UNAUDITED)

OTHER DEBT SECURITIES RISK: Secured loans that are not first lien, loans that
are unsecured and debt securities are subject to many of the same risks that
affect Senior Loans; however they are often unsecured and/or lower in the
issuer's capital structure than Senior Loans, and thus may be exposed to greater
risk of default and lower recoveries in the event of a default. This risk can be
further heightened in the case of below investment grade instruments.
Additionally, most fixed-income securities are fixed-rate and thus are generally
more susceptible than floating rate loans to price volatility related to changes
in prevailing interest rates.

PREPAYMENT RISK: Loans are subject to pre-payment risk. The degree to which
borrowers prepay loans, whether as a contractual requirement or at their
election, may be affected by general business conditions, the financial
condition of the borrower and competitive conditions among loan investors, among
others. As such, prepayments cannot be predicted with accuracy. Upon a
prepayment, either in part or in full, the actual outstanding debt on which the
Fund derives interest income will be reduced. The Fund may not be able to
reinvest the proceeds received on terms as favorable as the prepaid loan.

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.

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

             FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS) SEMI-ANNUAL
                        LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016


Dear Shareholders:

Thank you for your investment in First Trust Tactical High Yield ETF (the
"Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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. The Fund seeks to achieve its investment
objectives by investing at least 80% of its net assets including investment
borrowings, under normal market conditions, 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" bonds. 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. There can be no assurance that the Fund's investment
objective will be achieved. The Fund may not be appropriate for all investors.

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 Annual
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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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 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)   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
      rating of BBB- or higher. The credit ratings shown relate to the
      creditworthiness of the issuers of the underlying securities in the Fund,
      and not to the Fund or its shares. Credit ratings are subject to change.

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

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period February 27, 2013
(commencement of trading) through April 30, 2016. Shareholders may pay more than
NAV when they buy Fund shares and receive less than NAV when they sell those
shares because shares are bought and sold at current market price. Data
presented represents past performance and cannot be used to predict future
results.

FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (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 fees, if any, and other Fund
expenses. This Example is intended to help you understand your ongoing costs of
investing in the Fund and to compare these costs with the ongoing costs of
investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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 TACTICAL HIGH YIELD ETF (HYLS)

PORTFOLIO OF INVESTMENTS (CONTINUED)
APRIL 30, 2016 (UNAUDITED)

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

(b)   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 (the "1933 Act"), and may be resold in
      transactions exempt from registration, normally to qualified institutional
      buyers. Pursuant to procedures adopted by the Trust's Board of Trustees,
      this security has been determined to be liquid by First Trust Advisors
      L.P., the Fund's advisor (the "Advisor"). Although market instability can
      result in periods of increased overall market illiquidity, liquidity for
      each security is determined based on security-specific factors and
      assumptions, which require subjective judgment. At April 30, 2016,
      securities noted as such amounted to $258,584,462 or 32.4% of net assets.

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

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

(e)   These notes are Senior Payment-In-Kind ("PIK") Toggle Notes whereby the
      issuer may, at its option, elect to pay interest on the notes (1) entirely
      in cash or (2) entirely in PIK interest. Interest paid in cash will accrue
      at the rate of 7.00% per annum ("Cash Interest Rate") and PIK interest
      will accrue on the notes at a rate per annum equal to the Cash Interest
      Rate plus 75 basis points. For the six months ended April 30, 2016, this
      security paid all of its interest in cash.

(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 London Inter-Bank Offered Rate
      ("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. The interest rate
      shown reflects the rate in effect at April 30, 2016. When a range of rates
      is disclosed, the Fund holds more than one contract within the same
      tranche at varying rates.

(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)   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 April 30, 2016, securities noted as such are valued at
      $464,470 or 0.06% of net assets.

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

(j)   This issuer is in default but interest is still being accrued by the Fund
      and paid by the issuer.

(k)   Interest rate shown reflects yield as of April 30, 2016.

(l)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2016, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $11,564,002 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $17,553,235.

* See Portfolio of Investments for industry breakout. Industry categories
  are only shown separately if they include holdings in two or more levels
  or have holdings in only Level 3.

There were no transfers between Level 1 and Level 2.

All transfers in and out of Level 3 during the period are assumed to be
transferred on the last day of the period at their current value. As of April
30, 2016, the Fund transferred Senior Floating-Rate Loan Interests valued at
$134,539 from Level 2 to Level 3 of the fair value hierarchy. The Senior
Floating-Rate Loan Interests that transferred from Level 2 to Level 3 did so
primarily as a result of a change in information obtained from an independent
third-party pricing service relating to the market activity of individual Senior
Floating-Rate Loan Interests and a lack of trading activity in certain Senior
Floating-Rate Loan Interests.

As of April 30, 2016, the Fund transferred Corporate Bonds valued at $1,010,610
from Level 2 to Level 3 of the fair value hierarchy. The Corporate Bonds that
transferred from Level 2 to Level 3 did so primarily as a result of a change in
information obtained from an independent third-party pricing service relating to
the market activity of individual Corporate Bonds and a lack of trading activity
in certain Corporate Bonds.

Level 3 Senior Floating-Rate Loan Interests that are fair valued by the
Advisor's Pricing Committee are footnoted in the Portfolio of Investments. Level
3 Senior Floating-Rate Loan Interests are valued based on either third-party
pricing services prices obtained from dealer runs and indicative sheets from
brokers or are valued using broker quotes. The values are based on unobservable
and non-quantitative inputs. The Trust's Board of Trustees has adopted valuation
procedures that are utilized by the Advisor's Pricing Committee to oversee
day-to-day valuation of the Fund's investments. The Advisor's Pricing Committee,
through the Fund's fund accounting agent, monitors daily pricing via tolerance
checks and stale and unchanged price reviews. The Advisor's Pricing Committee
also reviews monthly back testing of pricing service prices by comparing sales
prices of the Fund investments to prior day pricing service prices.
Additionally, the Advisor's Pricing Committee reviews periodic information from
the Fund's third-party pricing service that compares secondary market trade
prices to their daily valuations.

      connection with a trade error. The payment from the advisor represents
      less than $0.01 per share and had no effect on the Fund's total return.

(c)   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.

(d)   Annualized.

(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 TACTICAL HIGH YIELD ETF (HYLS)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust Tactical High Yield ETF (the "Fund"), 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. The
Fund seeks to achieve its investment objectives by investing at least 80% of its
net assets including investment borrowings, under normal market conditions, 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" bonds. 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. There can be no assurance that
the Fund's investment objective will be achieved. The Fund may not be
appropriate for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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
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 an independent 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)
                           APRIL 30, 2016 (UNAUDITED)

      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 Loans(1) 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 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 60
      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 (the "1933 Act")) for which a 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 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;

           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.

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                           APRIL 30, 2016 (UNAUDITED)

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, 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.
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.

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
did not have any when-issued, delayed-delivery, or forward purchase commitments
as of April 30, 2016.

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
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 April 30, 2016, the Fund had $59,754,471
in restricted cash associated with investments sold short and $63,483,097 of
investments sold short as shown on the Statement of Asset and Liabilities.
Interest is charged on these balances at a rate equal to the Federal Funds rate
plus 75 basis points and is charged on payable credit margin balances at a rate
equal to the Federal Funds rate less 40 basis points. At April 30, 2016, the
Fund had a debit margin balance with an interest rate of 1.04%. For the six
months ended April 30, 2016, margin interest expense was $86,438, which is shown
in "Margin interest expense" on the Statement of Operations. For the six months
ended April 30, 2016, the average margin balance and interest rates were
$16,135,229 and 1.04%, respectively.

                           APRIL 30, 2016 (UNAUDITED)

D. UNFUNDED LOAN COMMITMENTS

The Fund may enter into 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. The Fund had no unfunded loan commitments as of April 30, 2016.

E. RESTRICTED SECURITIES

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the 1933 Act. Prior
to registration, restricted securities may only be resold in transaction exempt
from registration under Rule 144A under the 1933 Act, normally to qualified
institutional buyers. As of April 30, 2016, the Fund held restricted securities
as shown in the following table that the Advisor has deemed illiquid pursuant to
procedures adopted by the Fund's Board of Trustees. Although market instability
can result in periods of increaded overall market illiquidity, liquidity for
each security is determined based on security-specified factors and assumptions,
which require subjective judgement.The Fund does not have the right to demand
that such securities be registered. These securities are valued according to the
valuation procedures as stated in the Portfolio Valuation note (Note 2A) and are
not expressed as a discount to the carrying value of a comparable unrestricted
security. There are no unrestricted securities with the same maturity dates and
yields for these issuers.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund. The Fund distributes its net realized capital gains, if any, to
shareholders 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.

The tax character of distributions paid during the fiscal year ended October 31,
2015 was as follows:

Distributions paid from:
Ordinary income.................................      $   24,914,521
Capital gain....................................                  --
Return of capital...............................             332,485

As of October 31, 2015, the components of distributable earnings on a tax basis
for the Fund were as follows:

Undistributed ordinary income...................      $           --
Accumulated capital and other losses............            (930,645)
Net unrealized appreciation (depreciation)......         (15,965,702)

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.


                                                                         Page 29

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                           APRIL 30, 2016 (UNAUDITED)

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
As of October 31, 2015, the Fund has non-expiring capital loss carryforwards of
$930,645 for federal income tax purposes. 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.

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, 2015, 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. The taxable years ended 2013,
2014 and 2015 remain open to federal and state audit. As of April 30, 2016,
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.

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.

 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, distribution and service fees pursuant to a 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.

During the year ended October 31, 2015, the Fund received a payment from the
Advisor of $24,541 in connection with a trade error.

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

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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. 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 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.
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

                           APRIL 30, 2016 (UNAUDITED)

                                 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 $135 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. For the six months
ended April 30, 2016, the Fund did not have any outstanding borowings under the
Line of Credit.

                 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 Partcipant"). In order to purchase Creation Units of the 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. 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 is based on the composition of the securities included
in the Fund's portfolio and the countries in which the transactions are settled.
The Creation Transaction Fee is currently $500. 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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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, 2017.

                               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.


                                                                         Page 31

                              RISK CONSIDERATIONS

RISKS ARE INHERENT IN ALL INVESTING. YOU SHOULD CONSIDER THE FUND'S INVESTMENT
OBJECTIVES, RISKS, CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. YOU CAN
DOWNLOAD THE FUND'S PROSPECTUS AT HTTP://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 THE FUND. FOR ADDITIONAL INFORMATION ABOUT THE
RISKS ASSOCIATED WITH INVESTING IN THE FUND, PLEASE SEE THE FUND'S STATEMENT OF
ADDITIONAL INFORMATION, AS WELL AS OTHER REGULATORY FILINGS. READ THESE
DOCUMENTS CAREFULLY BEFORE YOU INVEST. FIRST TRUST PORTFOLIOS L.P. IS THE
DISTRIBUTOR OF THE FIRST TRUST EXCHANGE-TRADED FUND IV.

The following summarizes some of the risks that should be considered for the
Fund.

BANK LOANS RISK. An investment in bank loans subjects the Fund to credit risk,
which is heightened for bank loans in which the Fund invests because companies
that issue such loans tend to be highly leveraged and thus are more susceptible
to the risks of interest deferral, default and/or bankruptcy. Senior Loans, in
which the Fund may invest, are usually rated below investment grade but may also
be unrated. As a result, the risks associated with these Senior Loans are
similar to the risks of high yield fixed income instruments. An economic
downturn would generally lead to a higher non-payment rate, and a Senior Loan
may lose significant market value before a default occurs. Moreover, any
specific collateral used to secure a Senior Loan may decline in value or become
illiquid, which would adversely affect the Senior Loan's value. Unlike the
securities markets, there is no central clearinghouse for loan trades, and the
loan market has not established enforceable settlement standards or remedies for
failure to settle. Therefore, portfolio transactions in Senior Loans may have
uncertain settlement time periods. Senior Loans are subject to a number of risks
described elsewhere in this prospectus, including liquidity risk and the risk of
investing in below investment grade fixed income instruments. Furthermore,
increases in interest rates may result in greater volatility of Senior Loans and
average duration may fluctuate with fluctuations in interest rates.

CALL RISK: If an issuer calls higher-yielding securities held by the Fund,
performance could be adversely impacted.

CASH TRANSACTIONS RISK: The Fund will, under most circumstances, effect a
portion of creations and redemptions for cash, rather than in-kind securities.
As a result, an investment in the Fund may be less tax-efficient than an
investment in an exchange-traded fund that effects its creations and redemption
for in-kind securities. Because the Fund may effect a portion of redemptions for
cash, it may be required to sell portfolio securities in order to obtain the
cash needed to distribute redemption proceeds. A sale of shares may result in
capital gains or losses and may also result in higher brokerage costs.

CONVERTIBLE BONDS RISK: The market values of convertible bonds tend to decline
as interest rates increase and, conversely, to increase as interest rates
decline. A convertible bond's market value also tends to reflect the market
price of the common stock of the issuing company.

COUNTERPARTY RISK: Certain Derivative Instruments that involve counterparties
subject the Fund to the risk that the counterparty could default on its
obligations under the agreement, either through the counterparty's bankruptcy or
failure to perform its obligations. In the event of default, the Fund could
experience lengthy delays in recovering some or all of its assets or no recovery
at all. The Fund's investments in the futures markets also introduce the risk
that its futures commission merchant ("FCM") would default on an obligation set
forth in an agreement between the Fund and the FCM, including the FCM's
obligation to return margin posted in connection with the Fund's futures
contracts.


                                                                         Page 33

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

                   FIRST TRUST TACTICAL HIGH YIELD ETF (HYLS)
                           APRIL 30, 2016 (UNAUDITED)

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. Credit risk may be heightened
for the Fund because it invests a substantial portion of its net assets in high
yield or "junk" debt; such securities, while generally offering higher yields
than investment grade debt with similar maturities, involve greater risks,
including the possibility of dividend or interest deferral, default or
bankruptcy, and are regarded as predominantly speculative with respect to the
issuer's capacity to pay dividends or interest and repay principal. Credit risk
is heightened for loans in which the Fund invests because companies that issue
such loans tend to be highly leveraged and thus are more susceptible to the
risks of interest deferral, default and/or bankruptcy.

CURRENCY RISK: Because the Fund's net asset value is determined on the basis of
U.S. dollars and the Fund invests in foreign securities, you may lose money if
the local currency of a foreign market depreciates against the U.S. dollar, even
if the local currency value of the Fund's holdings goes up. The Fund intends to
hedge its non-U.S. dollar holdings.

DERIVATIVES RISK: The use of Derivative Instruments can lead to 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 Instruments.
These risks are heightened when the 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.

DISTRESSED SECURITIES RISK: The Fund may invest in Distressed Securities,
including stressed, distressed and bankrupt issuers and debt obligations that
are in default. In any investment involving Distressed Securities, there exists
the risk that the transaction involving such securities will be unsuccessful.
Distressed Securities might be repaid only after lengthy workout or bankruptcy
proceedings, during which the issuer might not make any interest or other
payments. Many Distressed Securities are illiquid or trade in low volumes and
thus may be more difficult to value. 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."

HIGH YIELD SECURITIES RISK: High yield securities are subject to greater market
fluctuations and risk of loss than securities with higher ratings. These
securities are issued by companies that may have limited operating history,
narrowly focused operations, and/or other impediments to the timely payment of
periodic interest and principal at maturity. If the economy slows down or dips
into recession, the issuers of high yield securities may not have sufficient
resources to continue making timely payment of periodic interest and principal
at maturity. The market for high yield securities is smaller and less liquid
than that for investment grade securities. High yield securities are generally
not listed on a national securities exchange but trade in the over-the-counter
markets. Due to the smaller, less liquid market for high yield securities, the
bid-offer spread on such securities is generally greater than it is for
investment grade securities and the purchase or sale of such securities may take
longer to complete.

ILLIQUID SECURITIES RISK: Illiquid securities involve the risk that the
securities will not be able to be sold at the time desired by the Fund or at
prices approximately the value at which the Fund is carrying the securities on
its books.

INCOME RISK: If interest rates fall, the income from the Fund's portfolio will
decline as the Fund invests the proceeds from new share sales, or from matured
or called debt securities, at interest rates that are below the portfolio's
current earnings rate.

INTEREST RATE RISK: Interest rate risk is the risk that the value of the debt
securities in the Fund's portfolio will decline because of rising market
interest rates. Interest rate risk is generally lower for shorter term debt
securities and higher for longer term debt securities. Duration is a measure of
the expected price volatility of a debt security as a result of changes in
market rates of interest, based on, among other factors, the weighted average
timing of the debt security's expected principal and interest payments. In
general, duration represents the expected percentage in the value of a security
for an immediate 1% change in interest rates. Therefore, prices of debt
securities with shorter durations tend to be less sensitive to interest rate
changes than debt securities with longer durations. As the value of a debt
security changes over time, so will its duration.

LIQUIDITY RISK: The Fund invests a substantial portion of its assets in
lower-quality debt issued by companies that are highly leveraged. Lower-quality
debt tends to be less liquid than higher-quality debt. Moreover, smaller debt
issues tend to be less liquid than larger debt issues. If the economy
experiences a sudden downturn, or if the debt markets for such companies become
distressed, the Fund may have particular difficulty selling its assets in
sufficient amounts, at reasonable prices and in a sufficiently timely manner to
raise the cash necessary to meet any potentially heavy redemption requests by
Fund shareholders. As of the fourth quarter of 2015, the market for high yield
debt has experienced decreased liquidity, and investor perception of increased
risk has caused yield spreads to widen. Decreased liquidity may negatively
affect the Fund's ability to mitigate risk and meet redemptions.

                           APRIL 30, 2016 (UNAUDITED)

MANAGEMENT RISK: The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, the
advisor will apply investment techniques and risk analyses that may not have the
desired result. There can be no guarantee that the Fund will meet its investment
objectives.

MARKET RISK: Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in stock
prices. Overall stock values could decline generally or could underperform other
investments.

NON-U.S. SECURITIES RISK: 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.

OTHER DEBT SECURITIES RISK: Secured loans that are not first lien, loans that
are unsecured and debt securities are subject to many of the same risks that
affect senior loans; however they are often unsecured and/or lower in the
issuer's capital structure than senior loans, and thus may be exposed to greater
risk of default and lower recoveries in the event of a default. This risk can be
further heightened in the case of below investment grade instruments.
Additionally, most fixed-income securities are fixed-rate and thus are generally
more susceptible than floating rate loans to price volatility related to changes
in prevailing interest rates.

PREPAYMENT RISK: Loans are subject to pre-payment risk. The degree to which
borrowers prepay loans, whether as a contractual requirement or at their
election, may be affected by general business conditions, the financial
condition of the borrower and competitive conditions among loan investors, among
others. As such, prepayments cannot be predicted with accuracy. Upon a
prepayment, either in part or in full, the actual outstanding debt on which the
Fund derives interest income will be reduced. The Fund may not be able to
reinvest the proceeds received on terms as favorable as the prepaid loan.

SHORT SALE RISK: The Fund uses short sales for investment and risk management
purposes, including when the Fund's advisor anticipates that the market price of
securities will decline or in the aggregate will underperform the Index. In
times of unusual or adverse market, economic, regulatory or political
conditions, the Fund may not be able, fully or partially, to implement its short
selling strategy. Periods of unusual or adverse market, economic, regulatory or
political conditions may exist for relatively long periods of time. The Fund
will have substantial short positions and must borrow those securities to make
delivery to the buyer. The Fund may not be able to borrow a security that it
needs to deliver or it may not be able to close out a short position at an
acceptable price and may have to sell related long positions before it had
intended to do so. Thus, the Fund may not be able to successfully implement its
short sale strategy due to limited availability of desired securities or for
other reasons. 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.


                                                                         Page 35

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

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016

Dear Shareholders:

Thank you for your investment in First Trust Enhanced Short Maturity ETF (the
"Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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 instruments (collectively,
"Fixed Income Securities") issued by U.S. and non-U.S. public and private sector
entities. Fixed Income Securities will include the following types of fixed- and
variable-rate debt securities: corporate and government bonds and notes; agency
securities; instruments of non-U.S. issuers in developed markets; privately
issued securities; asset-backed securities; mortgage-related securities;
municipal bonds; and 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 below one year and the average maturity of the Fund's
portfolio is expected to be below three years.

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

The 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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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.

      creditworthiness of an issuer with respect to debt obligations. Ratings
      are measured highest to lowest on a scale that generally ranges from AAA
      to D for long-term ratings and A-1+ to C for short-term ratings.
      Investment grade is defined as those issuers that have a long-term credit
      rating of BBB- or higher or a short-term credit rating of A-3 or higher.

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 6, 2014 (commencement
of trading) through April 30, 2016. Shareholders may pay more than NAV when they
buy Fund shares and receive less than NAV when they sell those shares because
shares are bought and sold at current market price. Data presented represents
past performance and cannot be used to predict future results.

FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (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 fees, if any, and other
Fund expenses. This Example is intended to help you understand your ongoing
costs of investing in the Fund and to compare these costs with the ongoing costs
of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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. The interest rate shown reflects the
      rate in effect at April 30, 2016.

(b)   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., 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 April 30, 2016, securities noted as such amounted
      to $14,266,354 or 3.8% of net assets.

(c)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2016, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $225,041 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $226,143.

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust Enhanced Short Maturity ETF (the "Fund"), 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. 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 will
invest at least 80% of its net assets in a portfolio of U.S. dollar-denominated
fixed- and variable-rate instruments (collectively, "Fixed Income Securities")
issued by U.S. and non-U.S. public and private sector entities. Fixed Income
Securities will include the following types of fixed- and variable-rate debt
securities: corporate and government bonds and notes; agency securities;
instruments of non-U.S. issuers in developed markets; privately issued
securities; asset-backed securities; mortgage-related securities; municipal
bonds and money market securities. The Fund may also invest in investment
companies, such as ETFs, that invest in primarily Fixed Income Securities. The
Fund will limit its investments in asset-backed securities and non-agency
mortgage-backed securities (in the aggregate) to 20% of its net assets. The Fund
may also invest up to 20% of its net assets in floating rate loans. The floating
rate loans will represent amounts borrowed by companies or other entities from
banks and other lenders and a significant portion of such floating rate 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 below one year and the average maturity of the Fund's
portfolio is expected to be below three years.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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, municipal securities, 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 an independent 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;

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

            5)    benchmark securities;

            6)    bids and offers; and

            7)    reference data including market research publications.

      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.

      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, fixed income and other debt securities having a
      remaining maturity of 60 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 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 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:


                                                                         Page 23

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, 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.

C. AFFILIATED TRANSACTIONS

The Fund invests in an affiliated fund. Dividend income, realized gains and
losses, and change in appreciation (depreciation) from the affiliated fund 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 fund.

Amounts related to this investment for the six months ended April 30, 2016 are
as follows:



                                                  SHARE ACTIVITY
                               -----------------------------------------------------

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

The tax character of distributions paid during the fiscal year ended October 31,
2015 was as follows:

Distributions paid from:

Ordinary income.................................      $    2,887,800
Capital gain....................................                  --
Return of capital...............................                  --

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

As of October 31, 2015, the components of distributable earnings and net assets
on a tax basis for the Fund were as follows:

Undistributed ordinary income...................      $      413,174
Accumulated capital and other losses............          (1,505,466)
Net unrealized appreciation (depreciation)......            (337,236)

E. INCOME TAXES

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

The Fund 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, 2015, the
Fund had $1,505,466 of non-expiring capital loss carryforwards that may be
carried forward indefinitely.

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, 2015, 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. The taxable years ended 2014 and
2015 remain open to federal and state audit. As of April 30, 2016, 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.

F. EXPENSES

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

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

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

Pursuant to the Investment Management Agreement between the Trust and Advisor,
First Trust manages the investment of the Fund's assets and is responsible for
the Fund's expenses, including the cost of transfer agency, custody, fund
administration, legal, audit and other services, but excluding fee payments
under the Investment Management Agreement, interest, taxes, acquired fund fees
and expenses with the exception of those attributable to affiliated funds,
brokerage commissions and other expenses connected with the execution of
portfolio transactions, distribution and service fees pursuant to a 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 contractual agreements, First Trust has agreed to waive management
fees of 0.20% of average daily net assets until March 1, 2017. 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, 2017. 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, 2017. 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.


                                                                         Page 25

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. 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 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.
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. REVERSE STOCK SPLIT

On October 29, 2014, the Trust's Board of Trustees approved a one-for-two
reverse stock split, whereby each share of the Fund outstanding as of the close
of business on November 7, 2014 automatically converted to one-half share as of
the opening of business on November 10, 2014. For the fiscal year ended October
31, 2015, the share transactions on the Statements of Changes in Net Assets
reflect the actual transactions, including the impact of the reverse stock
split. As a result of the reverse stock split, fractional shares totaling 277
shares were redeemed and paid out to shareholders. The reverse stock split had
no impact on the overall value of a shareholder's investment in the Fund.

                      5. 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 six months ended April 30,
2016, were $32,333,399 and $109,129,826, respectively. The proceeds from sales
and paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the six months ended April 30, 2016 were
$14,620,661 and $66,204,522, respectively.

For the six months ended April 30, 2016, the Fund had no in-kind transactions.

                 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 is based on the composition of the securities included
in the Fund's portfolio and the countries in which the transactions are settled.
The Creation Transaction Fee is currently $500. 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.

                           APRIL 30, 2016 (UNAUDITED)

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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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, 2017.

                               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 there was the
following subsequent event:

On May 19, 2016, the Fund declared a distribution of $0.045 per share to
shareholders of record on May 24, 2016, payable May 31, 2016.


                                                                         Page 27

                              RISK CONSIDERATIONS

PRINCIPAL RISKS

You could lose money by investing in the Fund. An investment in the Fund is not
a deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other governmental agency. There can be no
assurance that the Fund's investment objective will be achieved.

ASSET-BACKED AND MORTGAGE-RELATED SECURITIES RISK. The risk of investing in
mortgage-related and other asset-backed securities, including interest rate
risk, extension risk and prepayment risk. Generally, rising interest rates tend
to extend the duration of fixed rate mortgage-related securities, making them
more sensitive to changes in interest rates. Extension risk is prevalent when in
a period of rising interest rates, the Fund holds mortgage-related securities
and such securities exhibit additional volatility. Prepayment risk is prevalent
when in a period of declining interest rates, borrowers may pay off their
mortgages sooner than expected. Prepayments can reduce the returns of the Fund
because the Fund may have to reinvest that money at the lower prevailing
interest rates. The Fund's investments in asset-backed securities are subject to
risks similar to those associated with mortgage-related securities, as well as
additional risks associated with the nature of the assets and the servicing of
those assets.

CALL RISK. If an issuer calls higher yielding debt instruments held by the Fund,
performance could be adversely impacted.

CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a
portion of creations and redemptions for cash, rather than in kind securities.
As a result, an investment in the Fund may be less tax efficient than an
investment in an ETF that effects its creations and redemption for in kind
securities. Because the Fund may effect a portion of redemptions for cash, it
may be required to sell portfolio securities in order to obtain the cash needed
to distribute redemption proceeds. A sale of shares may result in capital gains
or losses, and may also result in higher brokerage costs.

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.

FIXED INCOME SECURITIES RISK. An investment in the Fund involves risk associated
with an investment in fixed income securities including the risk that certain of
the securities in the Fund may not have the benefit of covenants that would
prevent the issuer from engaging in capital restructurings or borrowing
transactions in connection with corporate acquisitions, leveraged buyouts or
restructurings. This limitation could reduce the ability of the issuer to meet
its payment obligations and might result in increased credit risk. In addition,
certain of the securities may be redeemed or prepaid by the issuer, resulting in
lower interest payments received by the Fund and reduced distributions to
shareholders.

FLOATING RATE LOAN RISK. An investment in floating rate loans subjects the Fund
to credit risk, which is heightened for loans in which the Fund invests because
companies that issue such loans tend to be highly leveraged and thus are more
susceptible to the risks of interest deferral, default and/or bankruptcy. The
loans are usually rated below investment grade but may also be unrated. An
economic downturn would generally lead to a higher non-payment rate, and a loan
may lose significant market value before a default occurs. Moreover, any
specific collateral used to secure a loan may decline in value or become
illiquid, which would adversely affect the loan's value. Unlike the securities
markets, there is no central clearinghouse for loan trades, and the loan market
has not established enforceable settlement standards or remedies for failure to
settle. Therefore, portfolio transactions in loans may have uncertain settlement
time periods. Loans are subject to a number of risks described elsewhere in this

                 FIRST TRUST ENHANCED SHORT MATURITY ETF (FTSM)
                           APRIL 30, 2016 (UNAUDITED)

prospectus, including liquidity risk and the risk of investing in below
investment grade debt instruments. Floating rate loans are subject to prepayment
risk. The degree to which borrowers prepay loans, whether as a contractual
requirement or at their election, may be affected by general business
conditions, the financial condition of the borrower and competitive conditions
among loan investors, among others. As such, prepayments cannot be predicted
with accuracy. Upon a prepayment, either in part or in full, the actual
outstanding debt on which the Fund derives interest income will be reduced. The
Fund may not be able to reinvest the proceeds received on terms as favorable as
the prepaid loan.

HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject
to greater market fluctuations and risk of loss than securities with higher
ratings, and therefore, may be highly speculative. These securities are issued
by companies that may have limited operating history, narrowly focused
operations, and/or other impediments to the timely payment of periodic interest
and principal at maturity. If the economy slows down or dips into recession, the
issuers of high yield securities may not have sufficient resources to continue
making timely payment of periodic interest and principal at maturity. The market
for high yield securities is generally smaller and less liquid than that for
investment grade securities. High yield securities are generally not listed on a
national securities exchange but trade in the over the counter markets. Due to
the smaller, less liquid market for high yield securities, the bid offer spread
on such securities is generally greater than it is for investment grade
securities and the purchase or sale of such securities may take longer to
complete. In general, high yield securities may have a greater risk of default
than other types of securities.

ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be
illiquid. Illiquid securities involve the risk that the securities will not be
able to be sold at the time desired by the Fund or at prices approximately the
value at which the Fund is carrying the securities on its books.

INCOME RISK. Income from the Fund's fixed income investments could decline
during periods of falling interest rates.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the Fixed
Income Securities in the Fund's portfolio will decline because of rising market
interest rates. Interest rate risk is generally lower for shorter term Fixed
Income Securities and higher for longer term Fixed Income Securities. Duration
is a measure of the expected price volatility of a debt security as a result of
changes in market rates of interest, based on, among other factors, the weighted
average timing of the Fixed Income Security's expected principal and interest
payments. In general, duration represents the expected percentage change in the
value of a security for an immediate 1% change in interest rates. Therefore,
prices of Fixed Income Securities with shorter durations tend to be less
sensitive to interest rate changes than Fixed Income Securities with longer
durations. As the value of a Fixed Income Security changes over time, so will
its duration. Mortgage-related securities are particularly subject to the risk
that interest rate volatility may adversely impact the valuation and price of
such securities.

INVESTMENT COMPANIES RISK. The Fund may invest in the shares of other investment
companies, and therefore, the Fund's investment performance and risks may be
related to the investment performance and risks of the underlying funds. In
general, as a shareholder in other investment companies, the Fund bears its
ratable share of the underlying fund's expenses, and would be subject to
duplicative expenses to the extent the Fund invests in other investment
companies. Pursuant to a contractual agreement, the Fund's investment advisor
has agreed to reduce the management fee paid by the Fund 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 the Fund's
investment advisor.

MANAGEMENT RISK. The Fund is subject to management risk because it is an
actively managed portfolio. The Fund's investment advisor will apply investment
techniques and risk analyses that may not have the desired result. There can be
no guarantee that the Fund will meet its investment objectives.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in
securities prices. Overall security values could decline generally or could
underperform other investments.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the
Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the
Fund is only limited as to the percentage of its assets that may be invested in
the securities of any one issuer by the diversification requirements imposed by
the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest
a relatively high percentage of its assets in a limited number of issuers. As a
result, the Fund may be more susceptible to a single adverse economic or
regulatory occurrence affecting one or more of these issuers, experience
increased volatility and be highly invested in certain issuers.


                                                                         Page 29

                           APRIL 30, 2016 (UNAUDITED)

NON-U.S. SECURITIES RISK. The Fund invests in securities of non-U.S. 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.

PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and
selling portfolio securities to rebalance the Fund's exposure to various market
sectors. High portfolio turnover may result in the Fund paying higher levels of
transaction costs and generating greater tax liabilities for shareholders.
Portfolio turnover risk may cause the Fund's performance to be less than you
expect.

SOVEREIGN DEBT RISK. Investments in debt securities issued by foreign
governments ("Sovereign Debt") involve special risks because the governmental
authority that controls the repayment of the debt may be unwilling or unable to
repay the principal and/or interest when due in accordance with the terms of
such securities; the relative size of the debt service burden to the economy as
a whole; or the government debtor's policy towards the International Monetary
Fund and the political constraints to which a government debtor may be subject.
If an issuer of sovereign debt defaults on payments of principal and/or
interest, the Fund may have limited legal recourse against the issuer and/or
guarantor. In certain cases, remedies must be pursued in the courts of the
defaulting party itself, and the Fund's ability to obtain recourse may be
limited.

VOLATILITY RISK. The market price and net asset value of the Fund's shares and
the Fund's yield will change daily. There may be instances when the Fund will
experience large in flows and out flows, which will significantly alter the
Fund's size. At times, these fluctuations may negatively impact the Fund's
yield, result in increased transaction costs for the Fund and contribute to the
overall volatility of the Fund. The risk will be more prevalent when the Fund is
smaller in size, such as during the Fund's invest up period. An investor may
lose money by investing in this Fund because this Fund is not a money market
fund and may experience significant fluctuations in its net asset value.

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

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016


Dear Shareholders:

Thank you for your investment in First Trust Strategic Income ETF (the "Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan.

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 the 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 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 Exchange 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 emerging markets debt; (v) equity
securities of Energy Infrastructure Companies, 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 Team may seek to gain exposure to the Fund's investment categories
through investments in exchange-traded funds. The Fund seeks to achieve its
objectives by having each Management Team focus on those instruments within its
respective investment category. The Fund may add or remove investment categories
or Management Teams at the discretion of the Advisor.

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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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.

-----------------------------
(1)   The Blended Index is equally weighted to include these six indices: the
      Alerian MLP Index, Dow Jones U.S. Select Dividend Index, BofA Merrill
      Lynch Fixed Rate Preferred Securities Index, BofA Merrill Lynch U.S. High
      Yield Index, Barclays EM USD Aggregate Index and Barclays U.S. MBS Index.
      An index does not charge management fees or brokerage expenses, and no
      such fees or expenses were deducted from the index performance shown.
      Indices are unmanaged and an investor cannot invest directly in an index.

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
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period August 14, 2014 (commencement
of trading) through April 30, 2016. Shareholders may pay more than NAV when they
buy Fund shares and receive less than NAV when they sell those shares because
shares are bought and sold at current market price. Data presented represents
past performance and cannot be used to predict future results.

FIRST TRUST STRATEGIC INCOME ETF (FDIV)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (UNAUDITED)

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

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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.

      Financial Statements.

      table, multiplied by the average account value over the period (November
      1, 2015 through April 30, 2016), multiplied by 182/366 (to reflect the
      one-half year period).

      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 April 30, 2016, securities noted as such amounted
      to $173,282 or 1.2% of net assets.

      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $514,056.

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight 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 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 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 investments within its respective investment
category. The Fund may add or remove investment categories or Management Teams
at the discretion of the Advisor.

Under normal market conditions, the Fund will invest in various asset classes,
which include high-yield corporate bonds, senior floating-rate loan interests,
mortgage-related investments, preferred securities, international sovereign
bonds, equity securities of Energy Infrastructure Companies(1), certain of which
are master limited partnerships ("MLPs") and dividend paying U.S.
exchange-traded equity securities and depositary receipts. The Management Team
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 through investments
in exchange-traded funds.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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


-----------------------------
(1)   Energy Infrastructure Companies are publicly-traded MLPs, MLP affiliates,
      Canadian income trusts and their successor companies, pipeline companies,
      utilities, and other companies that are involved in operating or providing
      services in support of infrastructure assets such as pipeline, power
      transmission and petroleum and natural gas storage in the petroleum,
      natural gas and power generation industries.


                                                                         Page 19

                           APRIL 30, 2016 (UNAUDITED)

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 an independent 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.

      Forward foreign currency contracts are fair valued at the current day's
      interpolated foreign exchange rate, as calculated using the current day's
      spot rate, and the thirty, sixty, ninety, and one-hundred eighty day
      forward rates provided by an independent pricing service.

      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 60
      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 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

                           APRIL 30, 2016 (UNAUDITED)

to obtain a reliable market quotation; and a security whose price, as provided
by the 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 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 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).


                                                                         Page 21

                           APRIL 30, 2016 (UNAUDITED)

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, 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.

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. FORWARD FOREIGN CURRENCY CONTRACTS

The Fund is subject to foreign currency risk in the normal course of pursuing
its investment objectives. Forward foreign currency contracts are agreements
between two parties ("Counterparties") to exchange one currency for another at a
future date and at a specified price. The Fund uses forward foreign currency
contracts to facilitate transactions in foreign securities and to manage the
Fund's foreign currency exposure. These contracts are valued daily, and the
Fund's net equity therein, representing unrealized gain or loss on the contracts
as measured by the difference between the forward foreign exchange rates at the
dates of entry into the contracts and the forward rates at the reporting date,
is included in "Unrealized appreciation (depreciation) on forward foreign
currency contracts" on the Statement of Assets and Liabilities. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or the cost of) the closing transaction
and the Fund's basis in the contract. This realized gain or loss is included in
"Net realized gain (loss) on forward foreign currency contracts" on the
Statement of Operations. Risks arise from the possible inability of
counterparties to meet the terms of their contracts and from movement in
currency and securities values and interest rates. Due to the risks, the Fund
could incur losses in excess of the net unrealized value shown on the forward
foreign currency contracts table in the Portfolio of Investments. In the event
of default by the Counterparty, the Fund will provide notice to the Counterparty
of the Fund's intent to convert the currency held by the Fund into the currency
that the Counterparty agreed to exchange with the Fund. If a Counterparty
becomes bankrupt or otherwise fails to perform its obligations due to financial
difficulties, the Fund may experience significant delays in obtaining any
recovery in a bankruptcy or other reorganization proceeding. The Fund may obtain
only limited recovery or may obtain no recovery in such circumstances.

As of April 30, 2016, the Fund had no open forward foreign currency contracts.

D. 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.

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                           APRIL 30, 2016 (UNAUDITED)

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 contacts
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 payable or receivable" 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.

As of April 30, 2016, the Fund had no open futures contracts.

E. OPTIONS CONTRACTS

In the normal course of pursuing its investment objective, 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 futures contracts,
exchange-listed options, exchange-listed options on futures contracts, and
exchange-listed stock index options.

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 contract may be closed out by an offsetting
purchase or sale of a futures option of the same series. 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 or indices. The purchase of put options on futures contracts is
analogous to the purchase of puts on securities or indices 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 purchased options are included in "Net
realized gain (loss) on investments" 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. 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


                                                                         Page 23

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
shown in "Net change in unrealized appreciation (depreciation) on investments"
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 trasactions" 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 for fixed-income securities is included in "Net realized gain (loss) on
investments" on the Statement of Operations.

G. 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.

H. 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.

I. 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.

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 in the Fund's Portfolio of Investments at
April 30, 2016, and for the six months ended are as follows:

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                           APRIL 30, 2016 (UNAUDITED)

K. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund. The Fund distributes its net realized capital gains, if any, to
shareholders at least annually.

Distributions from net investment income and realized capital gains are
determined in accordance with 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 year ended October 31,
2015 was as follows:

Distributions paid from:
Ordinary income.................................      $      559,024
Capital gain....................................                  --
Return of capital...............................             208,980

As of October 31, 2015, the components of distributable earnings and net assets
on a tax basis for the Fund were as follows:

Undistributed ordinary income...................      $         (842)
Accumulated capital and other losses............            (365,713)
Net unrealized appreciation (depreciation)......            (321,690)

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 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, 2015, the
Fund had $365,713 of 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, 2015, 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. The taxable years ended 2014 and
2015 remain open to federal and state audit. As of April 30, 2016, 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.

M. 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.


                                                                         Page 25

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                           APRIL 30, 2016 (UNAUDITED)

The Fund and First Trust have retained the Sub-Advisors to provide
recommendations to the Advisor regarding the selection and on-going 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. 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. 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 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 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.
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 six months ended April 30, 2016,
the Advisor waived fees of $27,304.

During the year ended October 31, 2015, the Fund received a payment from the
Advisor of $23,478 in connection with a trade error.

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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. 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, 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.
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 six months ended April 30,
2016, were $326,101 and $7,235,100, respectively. The proceeds from sales and
paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the six months ended April 30, 2016 were

                           APRIL 30, 2016 (UNAUDITED)


                 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 is based on the composition of the securities included
in the Fund's portfolio and the countries in which the transactions are settled.
The Creation Transaction Fee is currently $500. 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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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. BORROWINGS

The Trust on behalf of the Fund, along with First Trust Series Fund and First
Trust Variable Insurance Trust, entered into a $135 million Credit Agreement
(the "BNYM 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
loan is charged by BNYM, which First Trust allocates amongst the funds that have
access to the BNYM Line of Credit. 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 during the six months ended April 30, 2016.

                              8. 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, 2017.

                               9. INDEMNIFICATION

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

                              RISK CONSIDERATIONS

PRINCIPAL RISKS

You could lose money by investing in the Fund. An investment in the Fund is not
a deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other governmental agency. There can be no
assurance that the Fund's investment objectives will be achieved.

CASH TRANSACTIONS RISK: The Fund will, under most circumstances, effect a
portion of creations and redemptions for cash, rather than in kind securities.
As a result, an investment in the Fund may be less tax efficient than an
investment in an ETF that effects its creations and redemption for in kind
securities. Because the Fund may effect a portion of redemptions for cash, it
may be required to sell portfolio securities in order to obtain the cash needed
to distribute redemption proceeds. A sale of shares may result in capital gains
or losses, and may also result in higher brokerage costs.

COVERED CALL RISK. The Fund may invest in covered call options. Covered call
risk is the risk that the Fund will forgo, during the option's life, the
opportunity to profit from increases in the market value of the security
covering the call option above the sum of the premium and the strike price of
the call, but has retained the risk of loss should the price of the underlying
security decline. In addition, as the Fund writes covered calls over more of its
portfolio, its ability to benefit from capital appreciation becomes more
limited. The writer of an option has no control over the time when it may be
required to fulfill its obligation as a writer of the option. Once an option
writer has received an exercise notice, it cannot effect a closing purchase
transaction in order to terminate its obligation under the option and must
deliver the underlying security at the exercise price.

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.

CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S.
currencies, or in securities that provide exposure to such currencies, currency
exchange rates or interest rates denominated in such currencies. Changes in
currency exchange rates and the relative value of non-U.S. currencies will
affect the value of the Fund's investment and the value of your Fund shares.
Currency exchange rates can be very volatile and can change quickly and
unpredictably. As a result, the value of an investment in the Fund may change
quickly and without warning and you may lose money.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the
underlying shares in their primary trading market. Any distributions paid to the
holders of depositary receipts are usually subject to a fee charged by the
depositary. Holders of depositary receipts may have limited voting rights, and
investment restrictions in certain countries may adversely impact the value of
depositary receipts because such restrictions may limit the ability to convert
the equity shares into depositary receipts and vice versa. Such restrictions may
cause the equity shares of the underlying issuer to trade at a discount or
premium to the market price of the depositary receipts.

                           APRIL 30, 2016 (UNAUDITED)

DERIVATIVES RISK. The use of options and other derivatives can lead to 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 derivatives.
These risks are heightened when the 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.

ENERGY INFRASTRUCTURE COMPANIES RISK. Energy Infrastructure Companies may be
directly affected by energy commodity prices, especially those companies that
own the underlying energy commodity. A decrease in the production or
availability of natural gas, natural gas liquids, crude oil, coal or other
energy commodities or a decrease in the volume of such commodities available for
transportation, processing, storage or distribution may adversely impact the
financial performance of Energy Infrastructure Companies. Energy Infrastructure
Companies are subject to significant federal, state and local government
regulation in virtually every aspect of their operations, including how
facilities are constructed, maintained and operated, environmental and safety
controls, and the prices they may charge for products and services. Various
governmental authorities have the power to enforce compliance with these
regulations and the permits issued under them and violators are subject to
administrative, civil and criminal penalties, including civil fines, injunctions
or both. Stricter laws, regulations or enforcement policies could be enacted in
the future which would likely increase compliance costs and may adversely affect
the financial performance of Energy Infrastructure Companies. Natural disasters,
such as hurricanes in the Gulf of Mexico, also may impact Energy Infrastructure
Companies.

Certain Energy Infrastructure Companies in the utilities industry are subject to
imposition of rate caps, increased competition due to deregulation, difficulty
in obtaining an adequate return on invested capital or in financing large
construction projects, limitations on operations and increased costs and delays
attributable to environmental considerations, and the capital market's ability
to absorb utility debt. In addition, taxes, government regulation, international
politics, price and supply fluctuations, volatile interest rates and energy
conservation may cause difficulties for these companies. Such issuers have been
experiencing certain of these problems to varying degrees.

EQUITY SECURITIES RISK. The Fund invests in equity securities. The value of the
shares will fluctuate with changes in the value of these 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 the current 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 the capital rises and borrowing costs increase.

FINANCIAL COMPANIES RISK. The Fund invests in financial companies, including
banks, thrifts and their holding companies. Financial companies are especially
subject to the adverse effects of economic recession, currency exchange rates,
government regulation, decreases in the availability of capital, volatile
interest rates, portfolio concentrations in geographic markets and in commercial
and residential real estate loans, and competition from new entrants in their
fields of business.

FIXED INCOME SECURITIES RISK. An investment in the Fund involves risk associated
with an investment in fixed income securities including the risk that certain of
the securities in the Fund may not have the benefit of covenants that would
prevent the issuer from engaging in capital restructurings or borrowing
transactions in connection with corporate acquisitions, leveraged buyouts or
restructurings. This limitation could reduce the ability of the issuer to meet
its payment obligations and might result in increased credit risk. In addition,
certain of the securities may be redeemed or prepaid by the issuer, resulting in
lower interest payments received by the Fund and reduced distributions to
shareholders.

HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject
to greater market fluctuations and risk of loss than securities with higher
ratings, and therefore, may be highly speculative. These securities are issued
by companies that may have limited operating history, narrowly focused
operations, and/or other impediments to the timely payment of periodic interest
and principal at maturity. If the economy slows down or dips into recession, the
issuers of high yield securities may not have sufficient resources to continue
making timely payment of periodic interest and principal at maturity. The market
for high yield securities is generally smaller and less liquid than that for
investment grade securities. High yield securities are generally not listed on a
national securities exchange but trade in the over-the-counter markets. Due to
the smaller, less liquid market for high yield securities, the bid-offer spread
on such securities is generally greater than it is for investment grade
securities and the purchase or sale of such securities may take longer to
complete.

ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be
illiquid. Illiquid securities involve the risk that the securities will not be
able to be sold at the time desired by the Fund or at prices approximately the
value at which the Fund is carrying the securities on its books.


                                                                         Page 31

                           APRIL 30, 2016 (UNAUDITED)

INCOME RISK. Income from the Fund's fixed income investments could decline
during periods of falling interest rates.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the debt
securities in the Fund's portfolio will decline because of rising market
interest rates. Interest rate risk is generally lower for shorter term debt
securities and higher for longer term investments. Duration is a measure of the
expected price volatility of a debt security as a result of changes in market
rates of interest, based on, among other factors, the weighted average timing of
the debt security's expected principal and interest payments. In general,
duration represents the expected percentage change in the value of a security
for an immediate 1% change in interest rates. Therefore, prices of debt
securities with shorter durations tend to be less sensitive to interest rate
changes than debt securities with longer durations. As the value of a debt
security changes over time, so will its duration. Mortgage-related securities
are particularly subject to the risk that interest rate volatility may adversely
impact the valuation and price of such securities.

INVESTMENT COMPANIES RISK. The Fund may invest in the shares of other investment
companies, and therefore, the Fund's investment performance and risks may be
related to the investment performance and risks of the underlying funds. In
general, as a shareholder in other investment companies, the Fund bears its
ratable share of the underlying fund's expenses, and would be subject to
duplicative expenses to the extent the Fund invests in other investment
companies. Pursuant to a contractual agreement, the Advisor has agreed to reduce
the management fee paid by the Fund 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 the Advisor.

LIQUIDITY RISK. The Fund invests a substantial portion of its assets in
lower-quality debt issued by companies that are highly leveraged. Lower-quality
debt tends to be less liquid than higher-quality debt. Moreover, smaller debt
issues tend to be less liquid than larger debt issues. If the economy
experiences a sudden downturn, or if the debt markets for such companies become
distressed, the Fund may have particular difficulty selling its assets in
sufficient amounts, at reasonable prices and in a sufficiently timely manner to
raise the cash necessary to meet any potentially heavy redemption requests by
Fund shareholders. As of the fourth quarter of 2015, the market for high yield
debt has experienced decreased liquidity, and investor perception of increased
risk has caused yield spreads to widen. Decreased liquidity may negatively
affect the Fund's ability to mitigate risk and meet redemptions.

MANAGEMENT RISK. The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, the
Management Teams will apply investment techniques and risk analyses that may not
have the desired result. There can be no guarantee that the Fund will meet its
investment objectives.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in
securities prices. Overall security values could decline generally or could
underperform other investments.

MLP RISK. An investment in MLP units involves risks which differ from an
investment in common stock of a corporation. Holders of MLP units have limited
control and voting rights on matters affecting the partnership. In addition,
there are certain tax risks associated with an investment in MLP units and
conflicts of interest may exist between common unit holders and the general
partner, including those arising from incentive distribution payments. In
addition, there is the risk that an MLP could be, contrary to its intention,
taxed as a corporation, resulting in decreased returns from such MLP.

MORTGAGE SECURITIES RISK. The Fund invests in mortgage-related securities,
including mortgage-backed securities, which may make the Fund more susceptible
to adverse economic, political or regulatory events that affect the value of
real estate. Changes in local, state and federal policies could negatively
impact the mortgage-related securities market, which include various government
initiated and sponsored homeowner assistance programs and eminent domain issues.
Mortgage-related securities may also face liquidity issues when the Fund seeks
to sell such securities, but is unable to find buyers at a bid ask spread to
make the transaction feasible. These securities are also subject to the risk
that the underlying borrowers may default on their mortgages, resulting in a
non-payment of principal and interest. Finally, the mortgage-related securities
market may be negatively impacted by regulatory changes including those that are
related to the mandate or existence of the government-sponsored enterprises,
Fannie Mae, Freddie Mac and Ginnie Mae. Mortgage-related securities are subject
to the risk that the rate of mortgage prepayments decreases, which extends the
average life of a security and increases the interest rate exposure.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the
Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the
Fund is only limited as to the percentage of its assets that may be invested in
the securities of any one issuer by the diversification requirements imposed by
the Internal Revenue Code of 1986, as amended (the "Code"). The Fund may invest

                    FIRST TRUST STRATEGIC INCOME ETF (FDIV)
                           APRIL 30, 2016 (UNAUDITED)

a relatively high percentage of its assets in a limited number of issuers. As a
result, the Fund may be more susceptible to a single adverse economic or
regulatory occurrence affecting one or more of these issuers, experience
increased volatility and be highly invested in certain issuers.

NON-U.S. SECURITIES RISK AND EMERGING MARKETS RISK. 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. These risks may be heightened for securities of companies
located in, or with significant operations in, emerging market countries.

PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and
selling portfolio securities to rebalance the Fund's exposure to various market
sectors. High portfolio turnover may result in the Fund paying higher levels of
transaction costs and generating greater tax liabilities for shareholders.
Portfolio turnover risk may cause the Fund's performance to be less than you
expect.

PREFERRED SECURITIES RISK. Preferred securities combine some of the
characteristics of both common stocks and bonds. Preferred securities are
typically subordinated to bonds and other debt instruments in a company's
capital structure in terms of priority to corporate income, and therefore will
be subject to greater credit risk than those debt instruments. Preferred
securities are also subject to credit risk, interest rate risk and income risk.

SENIOR LOAN RISK. An investment in senior loans subjects the Fund to credit
risk, which is heightened for loans in which the Fund invests because companies
that issue such loans tend to be highly leveraged and thus are more susceptible
to the risks of interest deferral, default and/or bankruptcy. The loans are
usually rated below investment grade but may also be unrated. An economic
downturn would generally lead to a higher non payment rate, and a loan may lose
significant market value before a default occurs. Moreover, any specific
collateral used to secure a loan may decline in value or become illiquid, which
would adversely affect the loan's value. Unlike the securities markets, there is
no central clearinghouse for loan trades, and the loan market has not
established enforceable settlement standards or remedies for failure to settle.
Therefore, portfolio transactions in loans may have uncertain settlement time
periods. Loans are subject to a number of risks described elsewhere in this
prospectus, including liquidity risk and the risk of investing in below
investment grade debt instruments. Floating rate loans are subject to prepayment
risk. The degree to which borrowers prepay loans, whether as a contractual
requirement or at their election, may be affected by general business
conditions, the financial condition of the borrower and competitive conditions
among loan investors, among others. As such, prepayments cannot be predicted
with accuracy. Upon a prepayment, either in part or in full, the actual
outstanding debt on which the Fund derives interest income will be reduced. The
Fund may not be able to reinvest the proceeds received on terms as favorable as
the prepaid loan.

SMALL FUND RISK. The Fund currently has fewer assets than larger funds, and like
other relatively smaller funds, large inflows and outflows may impact the Fund's
market exposure for limited periods of time. This impact may be positive or
negative, depending on the direction of market movement during the period
affected.

SMALLER COMPANIES RISK. The Fund invests in small and/or mid capitalization
companies. Such companies may be more vulnerable to adverse general market or
economic developments, and their securities may be less liquid and may
experience greater price volatility than larger, more established companies as a
result of several factors, including limited trading volumes, products or
financial resources, management inexperience and less publicly available
information. Accordingly, such companies are generally subject to greater market
risk than larger, more established companies.

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

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                           APRIL 30, 2016 (UNAUDITED)


Dear Shareholders:

Thank you for your investment in First Trust Low Duration Opportunities ETF (the
"Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment for
the six months ended April 30, 2016. Additionally, First Trust compiled the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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 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 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. Jim 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.

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.

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 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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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.

(1)   The ratings are by Standard & Poor's Ratings 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. Ratings
      are measured highest to lowest on a scale that generally ranges from AAA
      to D for long-term ratings and A-1+ to C for short-term ratings.
      Investment grade is defined as those issuers that have a long-term credit
      rating of BBB- or higher or a short-term credit rating of A-3 or higher.
      The credit ratings shown relate to the credit worthiness of the issuers of
      the underlying securities in the Fund, and not to the Fund or its shares.
      U.S. Treasury and U.S. Agency mortgage-backed securities appear under
      "Government". Credit ratings are subject to change.

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

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2016

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period November 5, 2014
(commencement of trading) through April 30, 2016. Shareholders may pay more than
NAV when they buy Fund shares and receive less than NAV when they sell those
shares because shares are bought and sold at current market price. Data
presented represents past performance and cannot be used to predict future
results.

FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (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 fees, if any, and other
Fund expenses. This Example is intended to help you understand your ongoing
costs of investing in the Fund and to compare these costs with the ongoing costs
of investing in other funds.

The Example is based on an investment of $1,000 invested at the beginning of the
period and held through the six-month period ended April 30, 2016.

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 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. The interest rate shown reflects the
      rate in effect at April 30, 2016.

(b)   Zero coupon security.

(c)   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., the Fund's
      advisor (the "Advisor"). Although market instability can result in periods
      of increased overall market illiquidity, liquidity for each security is
      determined based on security specific factors and assumptions, which
      require subjective judgment. At April 30, 2016, securities noted as such
      amounted to $1,537,728 or 4.3% of net assets.

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

(e)   Step-up security. A security where the coupon increases or steps up at a
      predetermined date. The interest rate shown reflects the rate in effect at
      April 30, 2016.

(f)   Interest rate shown reflects yield as of April 30, 2016.

(g)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2016, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $688,357 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $33,565.

IO     - Interest-Only Security - Principal amount shown represents par value on
         which interest payments are based.
PO     - Principal-Only Security
STRIPS - Separate Trading of Registered Interest and Principal of Securities.

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust Low Duration Opportunities ETF (the "Fund"), 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. 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 capital appreciation. 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 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, such as 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 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. Under normal market conditions, the Fund targets an estimated effective
duration of three years or less.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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
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:

                           APRIL 30, 2016 (UNAUDITED)

      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 an independent 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.

      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 60
      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 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 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 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;


                                                                         Page 23

            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

            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 April 30, 2016, 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 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 April 30, 2016, the Fund had no when-issued,
delayed-delivery or forward purchase commitments.

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

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                           APRIL 30, 2016 (UNAUDITED)

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" 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 contacts
are marked-to-market daily with the change in value recognized as a component of
"Net change in unrealized appreciation (depreciation) on futures" 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 payable or receivable" 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.

D. OPTIONS CONTRACTS

In the normal course of pursuing its investment objective, 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, actively manage interest rate
exposure, hedge foreign currency risk and actively manage foreign currency
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. 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 or indices. The purchase of put options on futures contracts is
analogous to the purchase of puts on securities or indices 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.

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.

                           APRIL 30, 2016 (UNAUDITED)

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. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly by
the Fund. The Fund distributes its net realized capital gains, if any, to
shareholders 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 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 period ended October
31, 2015, was as follows:


Distributions paid from:
Ordinary income.......................................   $      159,003
Capital gain..........................................               --
Return of capital.....................................               --

As of October 31, 2015, the components of distributable earnings and net assets
on a tax basis for the Fund were as follows:

Undistributed ordinary income.........................   $       15,304
Accumulated capital and other losses..................          (74,009)
Net unrealized appreciation (depreciation)............          110,496

I. 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.

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                           APRIL 30, 2016 (UNAUDITED)

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital loss carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2015, the
Fund had $66,589 of 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 period ended October 31, 2015, 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. The taxable year ended 2015
remains open to federal and state audit. As of April 30, 2016, 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.

J. 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.

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, acquired
fund fees and expenses, brokerage commissions and other expenses connected with
the execution of portfolio transactions, distribution and service fees pursuant
to a 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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each Fund's net assets. 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 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.
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 six months ended April 30,
2016, were $21,576,510 and $11,804,475, respectively. The proceeds from sales
and paydowns of U.S. Government securities and non-U.S. Government securities,
excluding short-term investments, for the six months ended April 30, 2016 were
$1,887,882 and $8,612,341, respectively.

For the six months ended April 30, 2016, the Fund had no in-kind transactions.


                                                                         Page 27

                 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


Page 28

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

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                           APRIL 30, 2016 (UNAUDITED)

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 is
based on the composition of the securities included in the Fund's portfolio and
the countries in which the transactions are settled. The Creation Transaction
Fee is currently $500. 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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. 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. BORROWINGS

The Trust on behalf of the Fund, along with First Trust Series Fund and First
Trust Variable Insurance Trust, has a $135 million Credit Agreement (the "BNYM
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 loan is
charged to BNYM, which First Trust will allocate amongst the funds that have
access to the BNYM Line of Credit. These fees are reflected on the Statement of
Operations in the Commitment Fees line item. 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 during the six months ended April 30, 2016.

                              8. 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, 2017.

                               9. 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.

                             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 there was the
following subsequent event:

On May 19, 2016, the Fund declared a distribution of $0.1275 per share to
shareholders of record on May 24, 2016, payable May 31, 2016.


                                                                         Page 29

                              RISK CONSIDERATIONS

You could lose money by investing in the Fund. An investment in the Fund is not
a deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other governmental agency. There can be no
assurance that the Fund's investment objectives will be achieved.

CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a
portion of creations and redemptions for cash, rather than in-kind securities.
As a result, an investment in the Fund may be less tax-efficient than an
investment in an exchange-traded fund that effects its creations and redemption
for in-kind securities. Because the Fund may effect a portion of redemptions for
cash, it may be required to sell portfolio securities in order to obtain the
cash needed to distribute redemption proceeds. A sale of shares may result in
capital gains or losses and may also result in higher brokerage costs.

COUNTERPARTY RISK. The Fund bears the risk that the counterparty to a mortgage
dollar roll, TBA Transaction, derivative or other contract with a third-party
may default on its obligations or otherwise fail to honor its obligations. If a
counterparty defaults on its payment obligations the Fund will lose money and
the value of an investment in Fund shares may decrease. In addition, the Fund
may engage in such investment transactions with a limited number of
counterparties.

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.

HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject
to greater market fluctuations and risk of loss than securities with higher
ratings, and therefore, are considered to be highly speculative. If the economy
slows down or dips into recession, the issuers of high yield securities may not
have sufficient resources to continue making timely payment of periodic interest
and principal at maturity. The market for high yield securities is generally
smaller and less liquid than that for investment grade securities. High yield
securities are generally not listed on a national securities exchange but trade
in the over-the-counter markets. Due to the smaller, less liquid market for high
yield securities, the bid-offer spread on such securities is generally greater
than it is for investment grade securities and the purchase or sale of such
securities may take longer to complete. In general, high yield securities may
have a greater risk of default than other types of securities.

ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be
illiquid. Illiquid securities involve the risk that the securities will not be
able to be sold at the time desired by the Fund or at prices approximately the
value at which the Fund is carrying the securities on its books.

INCOME RISK. Income from the Fund's fixed income investments could decline
during periods of falling interest rates.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the fixed
income securities in the Fund will decline because of rising market interest
rates. Interest rate risk is generally lower for shorter term investments, which
generally have shorter durations, and higher for longer term investments.
Mortgage-Related Investments are particularly subject to the risk that interest
rate volatility may adversely impact the valuation and price of such securities.

LIQUIDITY RISK. The Fund invests a substantial portion of its assets in
lower-quality debt issued by companies that are highly leveraged. Lower-quality
debt tends to be less liquid than higher-quality debt. Moreover, smaller debt
issues tend to be less liquid than larger debt issues. If the economy
experiences a sudden downturn, or if the debt markets for such companies become

               FIRST TRUST LOW DURATION OPPORTUNITIES ETF (LMBS)
                           APRIL 30, 2016 (UNAUDITED)

distressed, the Fund may have particular difficulty selling its assets in
sufficient amounts, at reasonable prices and in a sufficiently timely manner to
raise the cash necessary to meet any potentially heavy redemption requests by
Fund shareholders. As of the fourth quarter of 2015, the market for high yield
debt has experienced decreased liquidity, and investor perception of increased
risk has caused yield spreads to widen. Decreased liquidity may negatively
affect the Fund's ability to mitigate risk and meet redemptions.

MANAGEMENT RISK. The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, the
Fund's investment advisor will apply investment techniques and risk analyses
that may not have the desired result. There can be no guarantee that the Fund
will meet its investment objective.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in
securities prices. Overall securities values could decline generally or could
underperform other investments.

MORTGAGE-RELATED INVESTMENTS RISK. The Fund invests in Mortgage-Related
Investments, including mortgage-backed securities, which may make the Fund more
susceptible to adverse economic, political or regulatory events that affect the
value of real estate. Changes in local, state and federal policies could
negatively impact the Mortgage-Related Investments market, which include various
government initiated and sponsored homeowner assistance programs and eminent
domain issues. Mortgage-Related Investments are subject to the risk that the
rate of mortgage prepayments decreases, which extends the average life of a
security and increases the interest rate exposure. Mortgage-Related Investments
may also face liquidity issues when the Fund seeks to sell such securities, but
is unable to find buyers at a bid-ask spread to make the transaction feasible.
These securities are also subject to the risk that the underlying borrowers may
default on their mortgages, resulting in a non-payment of principal and
interest. Finally, the Mortgage-Related Investments market may be negatively
impacted by regulatory changes including those that are related to the mandate
or existence of the government-sponsored enterprises, FNMA, FHLMC and GNMA.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the
Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the
Fund is only limited as to the percentage of its assets that may be invested in
the securities of any one issuer by the diversification requirements imposed by
the Internal Revenue Code of 1986, as amended. The Fund may invest a relatively
high percentage of its assets in a limited number of issuers. As a result, the
Fund may be more susceptible to a single adverse economic or regulatory
occurrence affecting one or more of these issuers, experience increased
volatility and be highly invested in certain issuers.

PORTFOLIO TURNOVER RISK. The Fund's strategy may frequently involve buying and
selling portfolio securities to rebalance the Fund's exposure to various market
sectors. High portfolio turnover may result in the Fund paying higher levels of
transaction costs and generating greater tax liabilities for shareholders.
Portfolio turnover risk may cause the Fund's performance to be less than you
expect.

PREPAYMENT RISK. Mortgage-Related Investments are subject to pre-payment risk.
The degree to which borrowers prepay loans, whether as a contractual requirement
or at their election, may be affected by general business conditions, the
financial condition of the borrower and competitive conditions among loan
investors, among others. As such, prepayments cannot be predicted with accuracy.
Upon a prepayment, either in part or in full, the actual outstanding debt on
which the Fund derives interest income will be reduced. The Fund may not be able
to reinvest the proceeds received on terms as favorable as the prepaid loan.

REPURCHASE AGREEMENT RISK. The Fund's investment in repurchase agreements,
including mortgage dollar rolls and TBA Transactions, may be subject to market
and credit risk with respect to the collateral securing the agreements.
Investments in mortgage dollar rolls also may be subject to the risk that the
market value of the underlying obligations may decline prior to the expiration
of the agreement term.

SHORT SALES RISK. The Fund will incur a loss as a result of a short sale if the
price of the security sold short increases in value between the date of the
short sale and the date on which the Fund purchases the security to replace the
borrowed security. In addition, a lender may request, or market conditions may
dictate, that securities sold short be returned to the lender on short notice,
which may result in the Fund having to buy the securities sold short at an
unfavorable price. If this occurs, any anticipated gain to the Fund may be
reduced or eliminated or the short sale may result in a loss. In a rising stock
market, the Fund's short positions may significantly impact the Fund's overall
performance and cause the Fund to underperform traditional long-only equity
funds or to sustain losses, particularly in a sharply rising market. The use of
short sales may also cause the Fund to have higher expenses than other funds.
Because losses on short sales arise from increases in the value of the security
sold short, such losses are theoretically unlimited. By contrast, a loss on a
long position arises from decreases in the value of the security and is limited
by the fact that a security's value cannot go below zero. The Fund's investment


                                                                         Page 31

                           APRIL 30, 2016 (UNAUDITED)

advisor's use of short sales in combination with long positions in the Fund's
portfolio in an attempt to improve performance or reduce overall portfolio risk
may not be successful and may result in greater losses or lower positive returns
than if the Fund held only long positions. It is possible that the Fund's long
securities positions will decline in value at the same time that the value of
its short securities positions increase, thereby increasing potential losses to
the Fund. In addition, the Fund's short selling strategies may limit its ability
to fully benefit from increases in the equity markets. To the extent the Fund
invests the proceeds received from selling securities short in additional long
positions, the Fund is engaging in a form of leverage. The use of leverage may
increase the Fund's exposure to long positions and make any change in the Fund's
net asset value greater than it would be without the use of leverage. This could
result in increased volatility of returns.

SMALL FUND RISK. The Fund currently has fewer assets than larger funds, and like
other relatively smaller funds, large inflows and outflows may impact the Fund's
market exposure for limited periods of time. This impact may be positive or
negative, depending on the direction of market movement during the period
affected.

U.S. GOVERNMENT AND AGENCY SECURITIES RISK. The Fund may invest in U.S.
government obligations. U.S. government obligations include U.S. Treasury
obligations and securities issued or guaranteed by various agencies of the U.S.
government or by various instrumentalities, which have been established or
sponsored by the U.S. government. U.S. Treasury obligations are backed by the
"full faith and credit" of the U.S. government. Securities issued or guaranteed
by federal agencies and U.S. government sponsored instrumentalities may or may
not be backed by the full faith and credit of the U.S. government.

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

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016

Dear Shareholders:

Thank you for your investment in First Trust SSI Strategic Convertible
Securities ETF (the "Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment
since the Fund's inception date of November 3, 2015. Additionally, First Trust
compiled the Fund's financial statements for you to review. We encourage you to
read this report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices. Second, the tapering that began in 2014 by the Federal Reserve (the
"Fed") did not stop growth in the U.S. economy. Finally, the long-anticipated
rate hike by the Fed in December had little effect on the money supply, and the
stock market was not shocked by the hike. Early in 2016, many investors were
concerned that the volatility we saw in the market in 2015 would continue, and
it did. From December 31, 2015 through February 11, 2016, the S&P 500(R) Index
declined by 10.27%. Since then, the market has made a steady comeback, and as of
April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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 SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)

The First Trust SSI Strategic Convertible Securities ETF (the "Fund") is an
actively managed exchange-traded fund that seeks to deliver total return by
investing, under normal market conditions, at least 80% of its net assets
(including investment borrowings) in a diversified portfolio of U.S. and
non-U.S. convertible securities. The shares of the Fund are listed and traded on
the Nasdaq Stock Market LLC under the ticker symbol "FCVT."

FUND PERFORMANCE
NAV                                                      -1.93%

INDEX PERFORMANCE
BofA Merrill Lynch All US Convertible Index              -3.88%
--------------------------------------------------------------------------------

Total returns for the period since inception are calculated from the inception
date of the Fund. "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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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 price 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 SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (UNAUDITED)

As a shareholder of 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 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 (or since inception) and held through the six-month (or shorter) period
ended April 30, 2016.

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 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 SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)

PORTFOLIO OF INVESTMENTS (CONTINUED)
APRIL 30, 2016 (UNAUDITED)

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

(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 SSI Investment Management Inc., the
      sub-advisor. Although market instability can result in periods of
      increased overall market illiquidity, liquidity for each security is
      determined based on security-specific factors and assumptions, which
      require subjective judgment. At April 30, 2016, securities noted as such
      amounted to $389,386 or 8.0% of net assets.

(b)   Zero coupon security.

(c)   Multi-Step Coupon Bond - Coupon steps up or down at predetermined dates.
      The interest rate shown reflects the rate in effect at April 30, 2016.

(d)   Perpetual maturity.

(e)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2016, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $175,745 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $189,151.

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust SSI Strategic Convertible Securities ETF (the
"Fund"), 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 diversified portfolio U.S. and
non-U.S. convertible securities.

                     2. VALUATION AND INVESTMENT PRACTICES

The Fund, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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 net asset value ("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 valued on
      the basis of valuations provided by dealers who make markets in such
      securities or by an independent 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.


                                                                         Page 15

      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 60
      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 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 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 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 (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.

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 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.

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, 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.

C. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

Distributions from income and capital gains are determined in accordance with
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 has no impact on net assets or net asset value
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.

D. 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. As of April 30, 2016, 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.

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.


                                                                         Page 17

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

The Fund and First Trust have retained SSI Investment Management Inc. ("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, brokerage
commissions and other expenses connected with the execution of portfolio
transactions, distribution and service fees pursuant to a 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.

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. Prior to January 1, 2016, the fixed annual retainer was allocated pro
rata based on each fund's net assets. 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, 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.
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.

At a meeting on December 7, 2015, the Board of Trustees accepted Mr. Mark
Bradley's resignation from his position as the President and Chief Executive
Officer of the Fund, effective December 31, 2015. At the same meeting, the Board
of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and
Treasurer of the Trust, to serve as the President and Chief Executive Officer
and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as
the Treasurer, Chief Financial Officer and Chief Accounting Officer of the
Trust.

                      4. PURCHASES AND SALES OF SECURITIES

For the period ended April 30, 2016, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
for the Fund were $6,226,665 and $1,256,457, respectively. For the period ended
April 30, 2016, 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"). 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
aggregations) 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 creator 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 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 the countries in which the
transactions are settled. The Creation Transaction fee is currently $500. 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.

                           APRIL 30, 2016 (UNAUDITED)

Authorized Participants redeeming Creation Units must pay to BBH, 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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $500. The
Fund reserves the right to affect 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.

                              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, 2017.

                               7. INDEMNIFICATION

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

                              8. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events to the Fund through
the date the financial statements were issued, and has determined there was the
following subsequent event:

On May 19, 2016, the Fund declared a distribution of $0.03 per share to
shareholders of record on May 24, 2016, payable May 31, 2016.


                                                                         Page 19

                              RISK CONSIDERATIONS

You could lose money by investing in the Fund. An investment in the Fund is not
a deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other governmental agency. There can be no
assurance that the Fund's investment objective will be achieved.

BDC RISK. The Fund may invest in BDCs which may carry risks similar to those of
a private equity or venture capital fund. Investments in BDCs may be subject to
price volatility and lack of liquidity. Debt securities and preferred securities
issued by BDCs may be rated below investment grade (referred to as "junk"
bonds), including in the lowest possible rating category, or unrated. Shares of
BDCs are not redeemable at the option of the shareholder and they may trade in
the market at a discount to their net asset value. Moreover, a shareholder of a
BDC will indirectly bear its pro rata share of the fees and expenses incurred by
the BDC in which it invests, including advisory fees. The BDCs held by the Fund
may employ the use of leverage through borrowings or the issuance of preferred
stock. This leverage also subjects a BDC to increased risks, including the
likelihood of increased volatility and the possibility that a BDC's common share
income will fall if the dividend rate of the preferred shares or the interest
rate on any borrowings rises. The loss on a leveraged investment may far exceed
the principal amount invested. Moreover, the use of leverage may result in a BDC
having to liquidate holdings when it may not be advantageous to do so.
Investments in BDCs include risks associated with their holdings of smaller
issuers and private companies. A BDC may make investments with a larger amount
of risk of volatility and loss of principal than other investment options and
may also be highly speculative and aggressive. For example, BDCs may invest in
the debt of a company, which involves risk that the company may default on its
payments or declare bankruptcy, and many of the debt instruments in which a BDC
may invest will not be rated by a credit rating agency and may be below
investment grade quality (referred to as "junk" bonds). A BDC's investments are
generally less liquid than publicly traded securities and are subject to
restrictions on their resale. The illiquidity of a BDC's holdings may make it
difficult for the BDC to sell such investments if the need arises, and thus the
BDC may be unable to take advantage of market opportunities or it may be forced
to sell illiquid securities at a loss if it is required to raise cash for
operations. Some BDCs are listed and trade on an exchange and other BDCs are not
traded on an exchange and trade only in private transactions. BDCs that are not
traded on an exchange may be less liquid than those that are traded on an
exchange. An investment in BDCs may result in a complete loss of the investment.

CASH TRANSACTIONS RISK. The Fund will, under most circumstances, effect a
significant portion of creations and redemptions for cash, rather than in-kind
securities. As a result, an investment in the Fund may be less tax-efficient
than an investment in an ETF that effects its creations and redemptions for
in-kind securities. Because the Fund may effect a portion of redemptions for
cash, it may be required to sell portfolio securities in order to obtain the
cash needed to distribute redemption proceeds. A sale of shares may result in
capital gains or losses, and may also result in higher brokerage costs.

CONVERTIBLE SECURITIES RISK. Convertible securities have characteristics of both
equity and debt securities and, as a result, are exposed to certain additional
risks. If a convertible security held by the Fund is called for redemption or
conversion, the Fund could be required to tender it for redemption, convert it
into the underlying equity security or sell it to a third party, which may have
an adverse effect on the Fund's ability to achieve its investment objective. The
market values of convertible securities tend to decline as interest rates
increase. However, a convertible security's market value also tends to reflect
the market price of the equity security of the issuing company, particularly
when the price of the equity security is greater than the convertible security's
conversion price (i.e., the predetermined price or exchange ratio at which the
convertible security can be converted or exchanged for the underlying equity
security). Convertible securities are also exposed to the risk that an issuer is
unable to meet its obligation to make dividend or principal payments when due as
a result of changing financial or market conditions. Convertible securities
generally offer lower interest or dividend yields than non-convertible debt
securities of similar credit quality because of their potential for capital
appreciation. Moreover, there can be no assurance that convertible securities
will provide current income prior to conversion because the issuers of the
convertible securities may default on their obligations.

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

Mandatory convertible securities are a subset of convertible securities. The
conversion of such securities is not optional, and the conversion price at
maturity is based solely upon the market price of the underlying equity
security, which may be significantly less than par or the price (above or below
par) paid. Mandatory convertible securities generally are subject to a greater
risk of loss of value than securities convertible at the option of the holder.

Contingent convertible securities (which generally provide for conversion under
certain circumstances) are also a subset of convertible securities. They may
have some of the characteristics of high yield bonds (referred to as "junk"
bonds), while providing exposure to equity-like losses and volatility. Similar
to mandatory convertible securities (and unlike traditional convertible
securities), some contingent convertible securities provide for mandatory
conversion under certain circumstances. The mandatory conversion might be
automatically triggered, for instance, if a company fails to meet the minimum
amount of capital described in the security, the company's regulator makes a
determination that the security should convert or the company receives specified
levels of extraordinary public support. Additionally, contingent convertible
securities may contain features that limit an investor's ability to convert the
security into the underlying equity security unless certain conditions are met.
A typical feature may require that a security be convertible only when the sale
price of the underlying common stock exceeds the conversion price by a specified
percentage (e.g., the sale price of the common stock is greater than or equal to
130% of the conversion price) for a certain specified period of time (e.g., for
at least 20 days during a span of 30 consecutive days in a month), or upon the
occurrence of certain other specified conditions. Also, since the common stock
of the issuer may not pay a dividend, investors in these instruments could
experience a reduced income rate, potentially to zero, and conversion would
deepen the subordination of the investor, hence worsening standing in a
bankruptcy. Further, some contingent convertible securities have a set stock
conversion rate that would cause a reduction in value of the security if the
price of the stock is below the conversion price on the conversion date.
Additionally, some contingent convertible securities have characteristics
designed to absorb losses, where the liquidation value of the security may be
adjusted downward to below the original par value or written off entirely under
certain circumstances. The write-down of the security's par value may occur
automatically and would not entitle holders to institute bankruptcy proceedings
against the issuer. In addition, an automatic write-down could result in a
reduced income rate if the dividend or interest payment associated with the
security is based on the security's par value. Moreover, various contingent
convertible securities may contain features that limit an investor's ability to
convert the security unless certain conditions are met.

The values of certain synthetic convertible securities will respond differently
to market fluctuations than a traditional convertible security because such
synthetic convertibles are composed of two or more separate securities or
instruments, each with its own market value. In addition, if the value of the
underlying equity security or the level of the index involved in the convertible
component falls below the exercise price of the warrant or option, the warrant
or option may lose all value. Synthetic convertible securities created by other
parties generally have economic characteristics similar to those of a
traditional convertible security; however, the issuer of the synthetic
convertible security assumes the credit risk associated with the investment,
rather than the issuer of the underlying equity security into which the
instrument is convertible. Therefore, the Fund is subject to the credit risk
associated with the counterparty creating the synthetic convertible instrument.
Synthetic convertible securities may also be subject to additional liquidity
risk and to the risks associated with derivatives.

CREDIT RISK. 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. Credit risk may be heightened if the Fund invests
in "high yield" or "junk" securities; such securities involve greater risks than
investment grade debt securities with similar maturities, including the
possibility of dividend or interest deferral, default or bankruptcy, and are
regarded as predominantly speculative with respect to the issuer's capacity to
pay dividends or interest and repay principal.

CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S.
currencies, or in securities that provide exposure to such currencies, currency
exchange rates or interest rates denominated in such currencies. Changes in
currency exchange rates and the relative value of non-U.S. currencies will
affect the value of the Fund's investments and the value of your Fund shares.
Currency exchange rates can be very volatile and can change quickly and
unpredictably. As a result, the value of an investment in the Fund may change
quickly and without warning and you may lose money.

DEBT SECURITIES RISK. An investment in the Fund involves risk associated with an
investment in debt securities including the risk that certain of the securities
in the Fund may not have the benefit of covenants that would prevent the issuer
from engaging in capital restructurings or borrowing transactions in connection
with corporate acquisitions, leveraged buyouts or restructurings. This
limitation could reduce the ability of the issuer to meet its payment
obligations and might result in increased credit risk. In addition, certain of
the securities may be redeemed or prepaid by the issuer, resulting in lower
interest payments received by the Fund and reduced distributions to
shareholders.


                                                                         Page 21

                           APRIL 30, 2016 (UNAUDITED)

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the
underlying shares in their primary trading market. Any distributions paid to the
holders of depositary receipts are usually subject to a fee charged by the
depositary. Holders of depositary receipts may have limited voting rights, and
investment restrictions in certain countries may adversely impact the value of
depositary receipts because such restrictions may limit the ability to convert
shares into depositary receipts and vice versa. Such restrictions may cause
shares of the underlying issuer to trade at a discount or premium to the market
price of the depositary receipts.

DERIVATIVES RISK. The use of swaps, options, futures contracts, forward
contracts and other derivatives can lead to 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 derivatives. These risks are heightened
when the Fund's portfolio managers use derivatives to enhance the Fund's return,
rather than solely to hedge (or offset) the risk of a position or security held
by the Fund.

EQUITY SECURITIES RISK. The Fund may hold equity securities in its portfolio
through direct investments in equity securities or upon conversion of a
convertible security. The value of the Fund's shares will fluctuate with changes
in the value of these 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 the current 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 the capital
rises and borrowing costs increase.

ETNS RISK. ETNs are senior, unsecured, unsubordinated debt securities whose
returns are linked to the performance of a particular market benchmark or
strategy minus applicable fees. ETNs are subject to credit risk, and the value
of the ETN may drop due to a downgrade in the issuer's credit rating, despite
the underlying market benchmark or strategy remaining unchanged. The value of an
ETN may also be influenced by time to maturity, level of supply and demand for
the ETN, volatility and lack of liquidity in underlying assets, changes in the
applicable interest rates, changes in the issuer's credit rating and economic,
legal, political or geographic events that affect the referenced underlying
asset.

HIGH YIELD SECURITIES RISK. High yield securities, or "junk" bonds, are subject
to greater market fluctuations and risk of loss than securities with higher
ratings and, therefore, may be highly speculative. These securities are issued
by companies that may have limited operating history, narrowly focused
operations, and/or other impediments to the timely payment of periodic interest
and principal at maturity. If the economy slows down or dips into recession, the
issuers of high yield securities may not have sufficient resources to continue
making timely payment of periodic interest and principal at maturity. The market
for high yield securities is generally smaller and less liquid than that for
investment grade securities. High yield securities are generally not listed on a
national securities exchange but trade in the over-the-counter markets. Due to
the smaller, less liquid market for high yield securities, the bid-offer spread
on such securities is generally greater than it is for investment grade
securities and the purchase or sale of such securities may take longer to
complete. In general, high yield securities may have a greater risk of default
than other types of securities.

ILLIQUID SECURITIES RISK. Some of the securities held by the Fund may be
illiquid. Illiquid securities involve the risk that the securities will not be
able to be sold at the time desired by the Fund or at prices approximately the
value at which the Fund is carrying the securities on its books.

INCOME RISK. Income from the Fund's fixed income investments could decline
during periods of falling interest rates.

INTEREST RATE RISK. Interest rate risk is the risk that the value of the fixed
income securities in the Fund will decline because of rising market interest
rates. Interest rate risk is generally lower for shorter term investments and
higher for longer term investments.

MANAGEMENT RISK. The Fund is subject to management risk because it is an
actively managed portfolio. In managing the Fund's investment portfolio, the
sub-advisor of the Fund will apply investment techniques and risk analyses that
may not have the desired result. There can be no guarantee that the Fund will
meet its investment objective.

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general, may fall in value. Securities are subject
to market fluctuations caused by such factors as economic, political, regulatory
or market developments, changes in interest rates and perceived trends in
securities prices. Overall securities values could decline generally or could
underperform other investments.

NEW FUND RISK. The Fund currently has fewer assets than larger funds, and like
other relatively new funds, large inflows and outflows may impact the Fund's
market exposure for limited periods of time. This impact may be positive or
negative, depending on the direction of market movement during the period
affected. Also, during the initial invest-up period, the Fund may depart from
its principal investment strategies and invest a larger amount or all of its
assets in cash equivalents or it may hold cash.

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the
1940 Act. As a result, the Fund is only limited as to the percentage of its
assets which may be invested in the securities of any one issuer by the
diversification requirements imposed by the Internal Revenue Code of 1986, as
amended. The Fund may invest a relatively high percentage of its assets in a
limited number of issuers. As a result, the Fund may be more susceptible to a
single adverse economic or regulatory occurrence affecting one or more of these
issuers, experience increased volatility and be highly concentrated in certain
issuers.

NON-U.S. SECURITIES RISK. 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.

PREFERRED SECURITIES RISK. Preferred securities combine some of the
characteristics of both common stocks and bonds. Preferred securities are
typically subordinated to bonds and other debt instruments in a company's
capital structure in terms of priority to corporate income and therefore will be
subject to greater credit risk than those debt instruments. Preferred securities
are also subject to credit risk, interest rate risk and income risk.

RESTRICTED SECURITIES RISK. Investments in restricted securities could have the
effect of increasing the amount of the Fund's assets invested in illiquid
securities if qualified institutional buyers are unwilling to purchase these
securities. Illiquid and restricted securities may be difficult to dispose of at
the price at which the Fund has valued the securities and at the times when the
Fund believes it is desirable to do so. The market price of illiquid and
restricted securities generally is more volatile than that of more liquid
securities, which may adversely affect the price that the Fund recovers upon the
sale of such securities. Investment of the Fund's assets in illiquid and
restricted securities may restrict the Fund's ability to take advantage of
market opportunities.

WARRANTS RISK. The prices of warrants, which entitle the holder to purchase
equity securities at specific prices for a certain period of time, do not
necessarily move parallel to the prices of the underlying securities and likely
fluctuate more than the prices of the underlying securities. Warrants have no
voting rights, receive no dividends, and have no rights with respect to the
assets of the issuer.

                      ADVISORY AND SUB-ADVISORY AGREEMENTS

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

The Board of Trustees of the First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the Investment
Management Agreement (the "Advisory Agreement") with First Trust Advisors L.P.
("First Trust" or the "Advisor") on behalf of the First Trust SSI Strategic
Convertible Securities ETF (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 SSI Investment Management Inc. (the "Sub-Advisor"), for an initial two-year
term at a meeting held on January 21, 2015. The Board of Trustees determined
that the Agreements are in the best interests of the Fund in light of the extent
and quality of services expected to be 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. To assist the Board in its evaluation of the Agreements, the
Independent Trustees received a separate report from each of the Advisor and the
Sub-Advisor in advance of the Board meeting responding to a request for
information provided on behalf of the Independent Trustees that, among other
things, outlined the services to be provided by the Advisor and the Sub-Advisor
to the Fund (including the relevant personnel responsible for these services and
their experience); the proposed unitary fee structure for the Fund as compared
to fees charged by advisors to other comparable exchange-traded funds ("ETFs"),
and as compared to fees charged to other ETFs managed by First Trust; the
estimated expenses to be incurred in providing services to the Fund and the
potential for economies of scale, if any; financial data on the Advisor and the
Sub-Advisor; fall out benefits to First Trust and its affiliate, First Trust
Portfolios L.P. ("FTP"); and a summary of the Advisor's compliance program. The
Independent Trustees also met separately with their independent legal counsel to
discuss the information provided by the Advisor and the Sub-Advisor. The Board
applied its business judgment to determine whether the arrangements between the
Trust and First Trust and among the Trust, the Advisor and the Sub-Advisor are
reasonable business arrangements from the Fund's perspective as well as from the
perspective of shareholders.

In evaluating whether to approve the Agreements for the Fund, the Board
considered the nature, extent and quality of services to be provided by the
Advisor and the Sub-Advisor under the Agreements and considered that the
Advisor's employees provide management services to other ETFs and to other
investment companies in the First Trust fund complex with diligence and care.


                                                                         Page 23

          FIRST TRUST SSI STRATEGIC CONVERTIBLE SECURITIES ETF (FCVT)
                           APRIL 30, 2016 (UNAUDITED)

The Board considered that the Fund is not designed to track the performance of
an index and will employ an advisor/sub-advisor management structure. With
respect to the Advisory Agreement, the Board considered that First Trust will be
responsible for the overall management and administration of the Fund and
reviewed the services to be provided by First Trust to the Fund, including the
oversight of the Sub-Advisor. The Board considered the compliance program that
had been developed by First Trust and considered it includes a robust program
for monitoring the Sub-Advisor's compliance with the 1940 Act and the Fund's
investment objective and policies. It also considered the efforts expended by
First Trust in organizing the Trust and in arranging for other entities to
provide services to the Fund. With respect to the Sub-Advisory Agreement, the
Board noted the background and experience of the Sub-Advisor's portfolio
management team and the Sub-Advisor's investment style. At the meeting, the
Trustees received a presentation from five representatives of the Sub-Advisor,
including the Chief Executive Officer, the President, the Chief Investment
Officer and a portfolio manager, and were able to ask questions about the
Sub-Advisor and the Sub-Advisor's proposed investment strategies for the Fund.
The Sub-Advisor's representatives stated that the Sub-Advisor provides
sub-advisory services to a registered investment company and thus has
familiarity with the requirements of the 1940 Act. Since the Fund had yet to
commence investment operations, the Board could not consider the historical
investment performance of the Fund. In light of the information presented and
the considerations made, the Board concluded that the nature, extent and quality
of services to be provided to the Fund by the Advisor and the Sub-Advisor under
the Agreements are expected to be satisfactory.

The Board reviewed information regarding the proposed unitary fee structure for
the Fund. The Board noted that under the Fund's unitary fee arrangement, the
Fund would pay First Trust a fee equal to an annual rate of 0.95% of its average
daily net assets. The Board also noted that, from the unitary fee, First Trust
would pay the Sub-Advisor a sub-advisory fee equal to one half of any remaining
monthly unitary fee paid to the Advisor after the Fund's average expenses
accrued during the most recent twelve months are subtracted from the unitary fee
for that month. The Board also noted that First Trust would be responsible for
the Fund's ordinary operating expenses, including the cost of transfer agency,
custody, fund administration, legal, audit and other services, and license fees,
if any, but excluding the fee payments under the Advisory Agreement, interest,
taxes, brokerage commissions and other expenses connected with the execution of
portfolio transactions such as dividend and distribution expenses from
securities sold short and/or other investment-related costs, distribution and
service fees pursuant to a Rule 12b-1 plan, if any, and extraordinary expenses.
The Board reviewed information provided by Management Practice Inc. ("MPI"), an
independent source, as well as by First Trust, for the Fund on the advisory fees
and expense ratios of other comparable ETFs, but also noted First Trust's
statements about the limitations on the comparability of the peer groups with
the Fund, including that not all of the ETFs in the MPI peer group are actively
managed. The Board also considered supplemental information provided by First
Trust on advisory fees and expense ratios of all actively managed ETFs as of a
recent date. The Board noted that the Fund's expense ratio under its proposed
unitary fee was above the median expense ratio of its MPI peer group. The Board
compared the Fund's unitary fee to the total expense ratios (after fee waivers
and/or expense reimbursements, if any) of other First Trust ETFs, including
First Trust ETFs that pay a unitary fee, and to the advisory fees charged by
First Trust to other advisory clients, noting the Advisor's statement that it
provides services to First Trust Tactical High Yield ETF and First Trust Senior
Loan Fund, both of which are actively managed ETFs that invest in below grade
securities, the former of which also pays an annual unitary fee of 0.95%. In
light of the information considered and the nature, extent and quality of
services expected to be provided to the Fund under the Agreements, the Board
determined that the proposed unitary fee for the Fund was fair and reasonable.

The Board noted that the proposed unitary fee for the Fund was not structured to
pass the benefits of any economies of scale on to shareholders as the Fund's
assets grow. The Board noted that any reduction in fixed costs associated with
the management of the Fund would benefit the Advisor and the Sub-Advisor, but
that a unitary fee structure provides a level of certainty in expenses for the
Fund. The Board noted that First Trust has continued to invest in personnel and
infrastructure for the First Trust fund complex. The Board took the costs to be
borne by First Trust in connection with its services to be performed for the
Fund under the Advisory Agreement into consideration and noted that First Trust
was unable to estimate the profitability of the Advisory Agreement to First
Trust. The Board also considered that the Sub-Advisor was unable to estimate the
profitability of the Sub-Advisory Agreement to the Sub-Advisor and that the
Sub-Advisor would be paid by the Advisor from the unitary fee. The Board
considered that the sub-advisory fee rate was negotiated at arm's length between
the Advisor and the Sub-Advisor, an unaffiliated third party, and the fee is a
net fee payable after the Fund's ordinary operating expenses are paid. The Board
considered fall-out benefits described by the Advisor that may be realized from
its and FTP's relationship with the Fund. The Board considered fall out benefits
described by the Sub-Adviser that may be realized from its relationship with the
Fund, including from soft-dollar arrangements, and the Advisor's proposal that
the Sub-Advisor also serve as sub-advisor to a new closed-end fund being
organized by the Advisor. The Board also considered the Advisor's statement that
it or an affiliate may make an investment in the Sub-Advisor.

Based on all the information considered and the conclusions reached, the Board,
including the Independent Trustees, unanimously determined that the terms of the
Agreements are fair and reasonable and that the approval of the Agreements are
in the best interests of the Fund. No single factor was determinative in the
Board's analysis.

                        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
shares may therefore be less than what you paid for them. Accordingly, you can
lose money investing in the Fund. See "Risk Considerations" in the Additional
Information section of this report for a discussion of certain other risks of
investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
http://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 http:www.ftportfolios.com.

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

            FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2016

Dear Shareholders:

Thank you for your investment in First Trust Heitman Global Prime Real Estate
ETF (the "Fund").

First Trust Advisors L.P. ("First Trust") is pleased to provide you with the
semi-annual report which contains detailed information about your investment
since the Fund's inception date of November 11, 2015. Additionally, First Trust
compiled the Fund's financial statements for you to review. We encourage you to
read this report and discuss it with your financial advisor.

While markets were up and down during 2015, we believe there are three important
things to remember. First, the U.S. economy grew, despite the massive decline in
oil prices, and second, the tapering that began in 2014 by the Federal Reserve
(the "Fed") did not stop growth in the U.S. economy. Finally, the
long-anticipated rate hike by the Fed in December had little effect on the money
supply, and the stock market was not shocked by the hike. Early in 2016, many
investors were concerned that the volatility we saw in the market in 2015 would
continue, and it did. From December 31, 2015 through February 11, 2016, the S&P
500(R) Index declined by 10.27%. Since then, the market has made a steady
comeback, and as of April 30, 2016, the S&P 500(R) Index was up 13.39%.

First Trust believes that having a long-term investment horizon and being
invested in quality products can help you reach your goals, despite how the
market behaves. We have always maintained perspective about the markets and
believe investors should as well. We will continue to strive to provide quality
investments each and every day, which has been one of the hallmarks of our firm
since its inception 25 years ago.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on helping
investors like you reach your financial goals.

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

Total returns for the period since inception are calculated from the inception
date of the Fund. "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 between the highest bid and the lowest offer on the stock
exchange on which shares of the Fund are listed for trading as of the time that
the Fund's NAV is 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 price 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.

The following Frequency Distribution of Discounts and Premiums charts are
provided to show the frequency at which the bid/ask midpoint price for the Fund
was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period November 12, 2015
(commencement of trading) through April 30, 2016. Shareholders may pay more than
NAV when they buy Fund shares and receive less than NAV when they sell those
shares because shares are bought and sold at current market price. Data
presented represents past performance and cannot be used to predict future
results.

FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)

UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2016 (UNAUDITED)

As a shareholder of First Trust Heitman Global Prime Real Estate ETF (the
"Fund") you incur two types of costs: (1) transaction costs; and (2) ongoing
costs, including management fees, distribution and/or service 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 (or since inception) and held through the six-month (or shorter) period
ended April 30, 2016.

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 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 HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)
                           APRIL 30, 2016 (UNAUDITED)

                                1. ORGANIZATION

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

The Trust currently consists of eight funds that are offering shares. This
report covers the First Trust Heitman Global Prime Real Estate ETF (the "Fund"),
which trades under the ticker "PRME" on the NYSE Arca, Inc. ("NYSE Arca").
Unlike conventional mutual funds, the fund issues and redeems shares on a
continuous basis, as net asset value ("NAV"), only in large specified blocks
consisting of 50,000 shares called a "Creation Unit." Creation Units are issued
and redeemed principally in-kind for securities in which the Fund invests or for
cash or, in certain circumstances, a combination of both. 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 provide long-term total return. Under normal market
conditions, the Fund will seek to achieve its investment objective by investing
at least 80% of its net assets (including investment borrowings) in U.S. and
non-U.S. exchange-traded real estate securities, which includes real estate
investment trusts ("REITs"), real estate operating companies ("REOCs") and
common stocks or depositary receipts of companies primarily engaged in the real
estate industry (collectively, "Real Estate Securities"). 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, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under 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 net asset value ("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. 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. (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:

      Common stocks, real estate investment trusts ("REITs") 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.

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Trust's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended (the "1933 Act")) for which a pricing service is unable to
provide a market price; securities whose trading has been formally suspended; a

            FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)
                           APRIL 30, 2016 (UNAUDITED)

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 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 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 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.

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of April 30, 2016, is
included with the Fund's Portfolio of Investments.


                                                                         Page 13

                           APRIL 30, 2016 (UNAUDITED)

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 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. A
Fund records the character of distributions received from the REITs during the
year based on estimates available. The characterization of distributions
received by a Fund may be subsequently revised based on information received
from the REITs after their tax reporting periods conclude.

C. 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
shown in "Net change in unrealized appreciation (depreciation) on investments"
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 dividend received and 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 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
Statement of Operations.

D. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

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

Distributions from income and capital gains are determined in accordance with
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 has no impact on net assets or net asset value
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.

E. 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. As of April 30, 2016, 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.

F. EXPENSES

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

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

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

At a meeting held on December 7, 2015, the Board of Trustees accepted Mr. Mark
Bradley's resignation from his position as the President and Chief Executive
Officer of the Trust, effective December 31, 2015. At the same meeting, the
Board of Trustees elected Mr. James Dykas, formerly Chief Financial Officer and
Treasurer of the Trust, to serve as the President and Chief Executive Officer,
and Mr. Donald Swade, formerly an Assistant Treasurer of the Trust, to serve as
the Treasurer, Chief Financial Officer and Chief Accounting Officer of the
Trust.

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 based on net assets. Prior to January 1, 2016, the fixed annual retainer
was allocated pro rata based on each fund's net assets. 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, 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.
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 six months ended April 30, 2016, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
were $734,927 and $719,297, respectively.

For the six months ended April 30, 2016, the cost of in-kind purchases was
$1,996,815.

                 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"). In order to purchase Creation Units of the 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 aggregations) 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 creator 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
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 the countries in which the
transactions are settled. The Creation Transaction fee is currently $700. 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,


                                                                         Page 15

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 BBH, 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 vary and is based on the composition of the
securities included in the Fund's portfolio and the countries in which the
transactions are settled. The Redemption Transaction Fee is currently $700. The
Fund reserves the right to affect 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

                              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, 2017.

                               7. INDEMNIFICATION

The Trust, on behalf of the Fund, has a variety of indemnification obligations
under contracts with its service providers. The Fund's maximum exposure under
these arrangements is unknown. However, the Fund 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 to the Fund through
the date the financial statements were issued, and has determined there were no
subsequent events requiting recognition or disclosure in the financial
statements.

                              RISK CONSIDERATIONS

You could lose money by investing in the Fund. An investment in the Fund is not
a deposit of a bank and is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other governmental agency. There can be no
assurance that the Fund's investment objective will be achieved.

ASIA INVESTMENT RISK. The Fund invests, in part, in securities issued by
companies operating in Asia, and is therefore subject to certain risks
associated specifically with Asia. For example, some of the currencies of these
countries, including China, have experienced devaluations relative to the U.S.
dollar, and adjustments have been made periodically in certain of such
currencies. Certain countries, such as Indonesia, face serious exchange
constraints. Jurisdictional disputes also exist, for example, between South
Korea and North Korea. The Tokyo stock market, as measured by the Tokyo Stock
Price Index, has been volatile. Declines in the Tokyo stock market have made the
country's banks and financial institutions vulnerable. Furthermore, the natural
disasters that have impacted Japan and the ongoing recovery efforts have had a
negative effect on Japan's economy, and may continue to do so.

CONCENTRATION RISK. The Fund is concentrated in REITs and/or real estate
management and development companies. A fund concentrated in a single sector,
industry or group of industries is likely to present more risks than a fund that
is broadly diversified over several industries or sectors. Compared to the broad
market, an individual industry or sector may be more strongly affected by
changes in the economic climate, broad market shifts, moves in a particular
dominant stock, or regulatory changes.

CURRENCY RISK. The Fund may hold investments that are denominated in non-U.S.
currencies, or in securities that provide exposure to such currencies, currency
exchange rates or interest rates denominated in such currencies. Changes in
currency exchange rates and the relative value of non-U.S. currencies will
affect the value of the Fund's investments and the value of your Fund shares.
Currency exchange rates can be very volatile and can change quickly and
unpredictably. As a result, the value of an investment in the Fund may change
quickly and without warning and you may lose money.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the
underlying shares in their primary trading market. Any distributions paid to the
holders of depositary receipts are usually subject to a fee charged by the
depositary. Holders of depositary receipts may have limited voting rights, and
investment restrictions in certain countries may adversely impact the value of
depositary receipts because such restrictions may limit the ability to convert
shares into depositary receipts and vice versa. Such restrictions may cause
shares of the underlying issuer to trade at a discount or premium to the market
price of the depositary receipts.

EMERGING MARKETS RISK. Investments in securities of issuers located in emerging
market countries are considered speculative. Heightened risks of investing in
emerging markets securities include: (i) smaller market capitalization of
securities markets, which may suffer periods of relative illiquidity; (ii)
significant price volatility; (iii) restrictions on foreign investment; and (iv)
possible repatriation of investment income and capital. Furthermore, foreign
investors may be required to register the proceeds of sales and future economic
or political crises could lead to price controls, forced mergers, expropriation
or confiscatory taxation, seizure, nationalization or creation of government
monopolies. The currencies of emerging market countries may experience
significant declines against the U.S. dollar, and devaluation may occur
subsequent to investments in these currencies by the Fund. Inflation and rapid
fluctuations in inflation rates have had, and may continue to have, negative
effects on the economies and securities markets of certain emerging market
countries.


                                                                         Page 17

                           APRIL 30, 2016 (UNAUDITED)

EQUITY SECURITIES RISK. Because the Fund invests in equity securities, the value
of the Fund's shares will fluctuate with changes in the value of these 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 current 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.

EUROPE INVESTMENT RISK. The Fund invests in securities issued by companies
operating in Europe. The Fund is therefore subject to certain risks associated
specifically with Europe. A significant number of countries in Europe are member
states in the European Union, and the member states no longer control their own
monetary policies by directing independent interest rates for their currencies.
In these member states, the authority to direct monetary policies, including
money supply and official interest rates for the Euro, is exercised by the
European Central Bank. Furthermore, the European sovereign debt crisis and the
related austerity measures in certain countries have had, and continue to have,
a significant negative impact on the economies of certain European countries and
their future economic outlooks.

INTEREST RATE RISK. The Fund is subject to interest rate risk. Increases in
interest rates typically coincide with higher investor required returns and can
lower the present value of a REIT's future earnings stream if not met with a
commensurate increase in growth.

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

MARKET RISK. Market risk is the risk that a particular security owned by the
Fund or shares of the Fund in general may fall in value. Shares are subject to
market fluctuations caused by such factors as economic, political, regulatory or
market developments, changes in interest rates and perceived trends in
securities prices. Overall Fund share values could decline generally or could
underperform other investments.

NEW FUND RISK. The Fund currently has fewer assets than larger funds, and like
other relatively new funds, large inflows and outflows may impact the Fund's
market exposure for limited periods of time. This impact may be positive or
negative, depending on the direction of market movement during the period
affected.

NON-DIVERSIFICATION RISK. The Fund is classified as "non-diversified" under the
1940 Act. As a result, the Fund is only limited as to the percentage of its
assets which may be invested in the securities of any one issuer by the
diversification requirements imposed by the Internal Revenue Code of 1986, as
amended. The Fund may invest a relatively high percentage of its assets in a
limited number of issuers. As a result, the Fund may be more susceptible to a
single adverse economic or regulatory occurrence affecting one or more of these
issuers, experience increased volatility and be highly concentrated in certain
issuers.

NON-U.S. SECURITIES RISK. The Fund may invest in securities of non-U.S. 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.

REAL ESTATE INVESTMENT RISK. The Fund invests in companies in the real estate
industry, including REITs and REOCs. Therefore, the Fund is subject to the risks
associated with investing in real estate, which may include, but are not limited
to, fluctuations in the value of underlying properties; defaults by borrowers or
tenants; market saturation; changes in general and local economic conditions;
decreases in market rates for rents; increases in competition, property taxes,
capital expenditures or operating expenses; and other economic, political or
regulatory occurrences affecting companies in the real estate industry.

REIT INVESTMENT RISK. In addition to risks related to investments in real estate
generally, investing in REITs involves certain other risks related to their
structure and focus, which include, but are not limited to, dependency upon
management skills, limited diversification, the risks of locating and managing
financing for projects, heavy cash flow dependency, possible default by
borrowers, the costs and potential losses of self-liquidation of one or more
holdings, the risk of a possible lack of mortgage funds and associated interest
rate risks, overbuilding, property vacancies, increases in property taxes and
operating expenses, changes in zoning laws, losses due to environmental damages,
changes in neighborhood values and appeal to purchases, the possibility of
failing to maintain exemptions from registration under the 1940 Act and, in many
cases, relatively small market capitalization, which may result in less market
liquidity and greater price volatility. REITs are also subject to the risk that
the real estate market may experience an economic downturn generally, which may
have a material effect on the real estate in which the REITs invest and their
underlying portfolio securities.

            FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)
                           APRIL 30, 2016 (UNAUDITED)


             ADVISORY, SUB-ADVISORY AND SUB-SUB-ADVISORY AGREEMENTS

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

The Board of Trustees of the First Trust Exchange-Traded Fund IV (the "Trust"),
including the Independent Trustees, unanimously approved the Investment
Management Agreement (the "Advisory Agreement") with First Trust Advisors L.P.
("First Trust" or the "Advisor") on behalf of the First Trust Heitman Global
Prime Real Estate ETF (the "Fund"), the Investment Sub-Advisory Agreement (the
"Sub-Advisory Agreement") among the Trust, on behalf of the Fund, the Advisor
and Heitman Real Estate Securities LLC (the "Sub-Advisor"), and the Investment
Sub-Sub-Advisory Agreements (the "Sub-Sub-Advisory Agreements") among the Trust,
on behalf of the Fund, the Advisor, the Sub-Advisor and each of Heitman
International Real Estate Securities HK Limited ("Heitman HK") and Heitman
International Real Estate Securities GmbH ("Heitman GmbH" and together with
Heitman HK, the "Sub-Sub-Advisors"). The Sub-Sub-Advisory Agreements, the
Sub-Advisory Agreement and the Advisory Agreement are collectively referred to
as the "Agreements." The Agreements were approved for an initial two-year term
at a meeting held on March 8-9, 2015. The Board of Trustees determined that the
Agreements are in the best interests of the Fund in light of the extent and
quality of services expected to be 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. To assist the Board in its evaluation of the Agreements, the
Independent Trustees received a separate report from each of the Advisor and the
Sub-Advisor (including information on the Sub-Sub-Advisors) in advance of the
Board meeting responding to a request for information provided on behalf of the
Independent Trustees that, among other things, outlined the services to be
provided by the Advisor, the Sub-Advisor and the Sub-Sub-Advisors to the Fund
(including the relevant personnel responsible for these services and their
experience); the proposed unitary fee structure for the Fund as compared to fees
charged by advisors to other comparable exchange-traded funds ("ETFs") and
global REIT mutual funds, and as compared to fees charged to other ETFs managed
by First Trust; the estimated expenses to be incurred in providing services to
the Fund and the potential for economies of scale, if any; financial data on the
Advisor, the Sub-Advisor and the Sub-Sub-Advisors; fall out benefits to First
Trust and its affiliate, First Trust Portfolios L.P. ("FTP") and to the
Sub-Advisor and Sub-Sub-Advisors; and a summary of the Advisor's and the
Sub-Advisor's compliance program (which included the Sub-Sub-Advisors). The
Independent Trustees also met separately with their independent legal counsel to
discuss the information provided by the Advisor, the Sub-Advisor and the
Sub-Sub-Advisors. The Board applied its business judgment to determine whether
the arrangements between the Trust and First Trust; among the Trust, the Advisor
and the Sub-Advisor; and among the Trust, the Advisor, the Sub-Advisor and each
of Heitman HK and Heitman GmbH are reasonable business arrangements from the
Fund's perspective as well as from the perspective of shareholders.

In evaluating whether to approve the Agreements for the Fund, the Board
considered the nature, extent and quality of services to be provided by the
Advisor, the Sub-Advisor and the Sub-Sub-Advisors under the Agreements and
considered that the Advisor's employees provide management services to other
ETFs and to other investment companies in the First Trust fund complex with
diligence and care. The Board considered that the Fund is not designed to track
the performance of an index and will employ an
advisor/sub-advisor/sub-sub-advisor management structure. With respect to the
Advisory Agreement, the Board considered that First Trust will be responsible
for the overall management and administration of the Fund and reviewed the
services to be provided by First Trust to the Fund, including the oversight of
the Sub-Advisor and the Sub-Sub-Advisors. The Board considered the compliance
program that had been developed by First Trust and considered that it includes a
robust program for monitoring the Sub-Advisor's and Sub-Sub-Advisors' compliance
with the 1940 Act and the Fund's investment objective and policies. It also
considered the efforts expended by First Trust in organizing the Trust and in
arranging for other entities to provide services to the Fund. With respect to
the Sub-Advisory Agreement and Sub-Sub-Advisory Agreements, the Board noted the
background and experience of the Sub-Advisor's and Sub-Sub-Advisors' portfolio
management teams and the Sub-Advisor's and Sub-Sub-Advisors' investment style.
At the meeting, the Trustees received a presentation from representatives of the
Sub-Advisor and were able to ask questions about the Sub-Advisor and the
Sub-Sub-Advisors and their proposed investment strategies for the Fund. The
Sub-Advisor's representatives explained the reason for structuring the
sub-advisory relationship with two sub-sub-advisors, noting that both
Sub-Sub-Advisors are U.S. registered investment advisors that use the same Chief
Compliance Officer as the Sub-Advisor, and that the structure was created so
that the Sub-Advisor could achieve best execution by using its affiliates to
execute certain portfolio transactions. Since the Fund had yet to commence
investment operations, the Board could not consider the historical investment
performance of the Fund. In light of the information presented and the
considerations made, the Board concluded that the nature, extent and quality of
services to be provided to the Fund by the Advisor, Sub-Advisor and
Sub-Sub-Advisors under the Agreements are expected to be satisfactory.


                                                                         Page 19

            FIRST TRUST HEITMAN GLOBAL PRIME REAL ESTATE ETF (PRME)
                           APRIL 30, 2016 (UNAUDITED)

The Board reviewed information regarding the proposed unitary fee structure for
the Fund. The Board noted that under the Fund's unitary fee arrangement, the
Fund would pay First Trust a fee equal to an annual rate of 0.95% of its average
daily net assets. The Board also noted that, from the unitary fee, First Trust
would pay the Sub-Advisor a sub-advisory fee equal to one-half of any remaining
monthly unitary fee paid to the Advisor after the Fund's average expenses
accrued during the most recent twelve months are subtracted from the unitary fee
for that month, and that the Sub-Advisor would pay each of Heitman HK and
Heitman GmbH a pro-rata portion of the sub-advisory fee received from the
Advisor based on the proportion of assets managed by each. The Board also noted
that First Trust would be responsible for the Fund's ordinary operating
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 Advisory Agreement, interest, taxes, brokerage commissions and
other expenses connected with the execution of portfolio transactions such as
dividend and distribution expenses from securities sold short and/or other
investment-related costs, distribution and service fees payable pursuant to a
Rule 12b-1 plan, if any, and extraordinary expenses. The Board reviewed
information provided by Management Practice Inc. ("MPI"), an independent source,
as well as by First Trust, for the Fund on the advisory fees and expense ratios
of other comparable ETFs, as well as data provided by First Trust on advisory
fees and expense ratios of global REIT mutual funds. The Board noted that four
of the five funds in First Trust's and MPI's peer group overlapped, and that
most of the ETFs in the peer groups are not actively managed. The Board noted
that the Fund's expense ratio under its proposed unitary fee was above the
median expense ratio of its MPI peer group and within the range of the expense
ratios of the group of global REIT mutual funds provided by First Trust. The
Board compared the Fund's unitary fee to the total expense ratios (after fee
waivers and/or expense reimbursements, if any) of other First Trust ETFs,
including First Trust ETFs that pay a unitary fee, and to the advisory fees
charged by First Trust to other advisory clients, noting the Advisor's statement
that it provides services to First Trust FTSE EPRA/NAREIT Developed Markets Real
Estate Index Fund ("FFR"), an index ETF that seeks investment results that
correspond generally to the price and yield, before fees and expenses, of the
FTSE EPRA/NAREIT Developed Index. The Board noted that FFR pays a lower annual
unitary fee but considered that it is an index ETF and is not sub-advised. In
light of the information considered and the nature, extent and quality of
services expected to be provided to the Fund under the Agreements, the Board
determined that the proposed unitary fee for the Fund was fair and reasonable.

The Board noted that the proposed unitary fee for the Fund was not structured to
pass the benefits of any economies of scale on to shareholders as the Fund's
assets grow. The Board noted that any reduction in fixed costs associated with
the management of the Fund would benefit the Advisor, the Sub-Advisor and the
Sub-Sub-Advisors, but that a unitary fee structure provides a level of certainty
in expenses for the Fund. The Board noted that First Trust has continued to
invest in personnel and infrastructure for the First Trust fund complex. The
Board took the costs to be borne by First Trust in connection with its services
to be performed for the Fund under the Advisory Agreement into consideration and
noted that First Trust was unable to estimate the profitability of the Advisory
Agreement to First Trust. The Board considered estimated profitability
information provided for the Sub-Advisor and Sub-Sub-Advisors. The Board noted
that the Sub-Advisor would be paid by the Advisor from the unitary fee and the
Sub-Sub-Advisors would be paid from the sub-advisory fee. The Board considered
that the sub-advisory fee rate was negotiated at arm's length between the
Advisor and the Sub-Advisor, an unaffiliated third party, and the fee is a net
fee payable after the Fund's ordinary operating expenses are paid. The Board
considered fall-out benefits described by the Advisor that may be realized from
its and FTP's relationship with the Fund. The Board considered fall out benefits
described by the Sub-Advisor and Sub-Sub-Advisors that may be realized from
their relationship with the Fund, including from soft-dollar arrangements.

Based on all the information considered and the conclusions reached, the Board,
including the Independent Trustees, unanimously determined that the terms of the
Agreements are fair and reasonable and that the approval of the Agreements are
in the best interests of the Fund. No single factor was determinative in the
Board's analysis.
