                        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 by investing in the Fund. See "Risk Considerations" in the Additional
Information section of this report for a discussion of certain other risks of
investing in the Fund.

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

SHAREHOLDER LETTER

             FIRST TRUST PREFERRED SECURITIES AND INCOME ETF (FPE)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2015

Dear Shareholders:

Thank you for your investment in First Trust Preferred Securities and 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, 2015. Additionally, First Trust compiles the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

U.S. markets, fueled by accelerating growth and an accommodating Federal
Reserve, enjoyed a prosperous year in 2014. However, for the six months covered
by this report, some economic and global factors, including the continued
conflict in the Middle East and a sharp decline in oil prices, created
volatility in the U.S. and global markets. Another factor that has impacted
markets is the fact that many economists are predicting the Federal Reserve will
begin to raise interest rates this year.

As I have written previously, First Trust believes investors should maintain
perspective about the markets and have realistic expectations about their
investments. Markets will always go up and down, but we believe that having a
long-term investment horizon and being invested in quality products can help you
reach your goals.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value the relationship and will continue to focus on our disciplined
investment approach and long-term perspective to help investors reach their
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 PREFERRED SECURITIES AND INCOME ETF (FPE)

First Trust Preferred Securities and Income ETF's (the "Fund") investment
objective is to seek total return and to provide current income. Under normal
market conditions, the Fund invests at least 80% of its net assets (including
investment borrowings) in preferred securities ("Preferred Securities") and
income-producing debt securities ("Income Securities"). The Fund invests in
securities that are traded over-the-counter or listed on an exchange. For
purposes of the 80% test set forth above, securities of open-end funds,
closed-end funds or other exchange-traded funds ("ETFs") registered under the
Investment Company Act of 1940, as amended, that invest primarily in Preferred
Securities or Income Securities are deemed to be Preferred Securities or Income
Securities.

Preferred Securities held by the Fund generally pay fixed or adjustable-rate
distributions to investors and have preference over common stock in the payment
of distributions and the liquidation of a company's assets, but are generally
junior to all forms of the company's debt, including both senior and
subordinated debt. Certain of the Preferred Securities may be issued by trusts
or other special purpose entities created by companies specifically for the
purpose of issuing such securities. Income Securities that may be held by the
Fund include corporate bonds, high yield securities (commonly referred to as
"junk" bonds) and convertible securities. The broad category of corporate debt
securities includes debt issued by U.S. and non-U.S. companies of all kinds,
including those with small, mid and large capitalizations. Corporate debt may
carry fixed or floating rates of interest.

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



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 periods indicated. "Cumulative Total
Returns" represent the total change in value of an investment over the periods
indicated.

The Fund's per share net asset value ("NAV") is the value of one share of the
Fund and is computed by dividing the value of all assets of the Fund (including
accrued interest and dividends), less all liabilities (including accrued
expenses and dividends declared but unpaid), by the total number of outstanding
shares. The price used to calculate market return ("Market Price") is determined
by using the midpoint 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 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 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 Blended Benchmark consists of a 50/50 blend of the BofA Merrill Lynch
      Fixed Rate Preferred Securities Index and the BofA Merrill Lynch U.S.
      Capital Securities Index. The Blended Benchmark was added to reflect the
      diverse allocation of institutional preferred and hybrid securities in the
      Fund's portfolio. The indices do not charge management fees or brokerage
      expenses, and no such fees or expenses were deducted from the 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, 2015

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 12, 2013
(commencement of trading) through April 30, 2015. 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.

(1)   The Blended Benchmark consists of a 50/50 blend of the BofA Merrill Lynch
      Fixed Rate Preferred Securities Index and the BofA Merrill Lynch U.S.
      Capital Securities Index. The Blended Benchmark was added to reflect the
      diverse allocation of institutional preferred and hybrid securities in the
      Fund's portfolio. The indices do not charge management fees or brokerage
      expenses, and no such fees or expenses were deducted from the performance
      shown. Indices are unmanaged and an investor cannot invest directly in an
      index.

FIRST TRUST PREFERRED SECURITIES AND INCOME ETF (FPE)
UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2015 (UNAUDITED)


As a shareholder of First Trust Preferred Securities and 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, 2015.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)   Perpetual maturity.

(b)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at April 30, 2015. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(c)   Floating rate security. The interest rate shown reflects the rate in
      effect at April 30, 2015.

(d)   Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be illiquid by Stonebridge Advisors LLC,
      the Fund's sub-advisor (the "Sub-Advisor").

(e)   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 (see Note 2C - Restricted Securities in the Notes to Financial
      Statements).

(f)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A under the 1933 Act,
      and may be resold in transactions exempt from registration, normally to
      qualified institutional buyers. Pursuant to procedures adopted by the
      Trust's Board of Trustees, this security has been determined to be liquid
      by 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, 2015, securities noted as such
      amounted to $21,096,375 or 10.58% of net assets.

(g)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2015, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $3,102,658 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $1,161,231.

First Trust Exchange-Traded Fund III (the "Trust") is a non-diversified open-end
management investment company organized as a Massachusetts business trust on
January 9, 2008, 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 four funds that are offering shares. This report
covers the First Trust Preferred Securities and Income ETF (the "Fund"), which
trades under the ticker FPE on the NYSE Arca, Inc. 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 securities in
which the Fund invests or for cash or, in certain circumstances, a combination
of both. Except when aggregated in Creation Units, the shares are not redeemable
securities of the Fund.

The Fund is an actively managed exchange-traded fund. The investment objective
of the Fund is to seek total return and to provide current income. Under normal
market conditions, the Fund invests at least 80% of its net assets (including
investment borrowings) in preferred securities and income-producing debt
securities including corporate bonds, high-yield securities and convertible
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 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:

      Preferred stocks and other equity securities listed on any national or
      foreign exchange (excluding The NASDAQ(R) 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.

      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.

             FIRST TRUST PREFERRED SECURITIES AND INCOME ETF (FPE)
                           APRIL 30, 2015 (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 (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 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.

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, 2015, is
included with the Fund's Portfolio of Investments.


                                                                         Page 17

             FIRST TRUST PREFERRED SECURITIES AND INCOME ETF (FPE)
                           APRIL 30, 2015 (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. Amortization of premiums and accretion of
discounts are recorded using the effective interest method.

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 are not
known until after the REIT's 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. RESTRICTED SECURITIES

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the 1933 Act. Prior
to registration, restricted securities may only be resold in transactions exempt
from registration under Rule 144A under the 1933 Act, normally to qualified
institutional buyers. As of April 30, 2015, the Fund held restricted securities
as shown in the following table that Stonebridge Advisors LLC ("Stonebridge" or
the "Sub-Advisor") has deemed illiquid pursuant to procedures adopted by the
Trust's Board of Trustees. Although market instability can result in periods of
increased overall market illiquidity, liquidity for each security is determined
based on security-specific factors and assumptions, which require subjective
judgment. The Fund does not have the right to demand that such securities be
registered. These securities are valued according to the valuation procedures as
stated in the Portfolio Valuation note (Note 2A) and are not expressed as a
discount to the carrying value of a comparable unrestricted security. There are
no unrestricted securities with the same maturity dates and yields for these
issuers.

D. 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 have 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.

The tax character of distributions paid during the fiscal period ended October
31, 2014 was as follows:

Distributions paid from:
Ordinary income....................................         $    3,548,355
Capital gain.......................................                     --
Return of capital..................................                     --

As of October 31, 2014, the components of distributable earnings on a tax basis
were as follows:

Undistributed ordinary income......................         $      432,357
Accumulated capital and other losses...............             (5,759,772)
Net unrealized appreciation (depreciation).........                424,349

                           APRIL 30, 2015 (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 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 and
2014 remain open to federal and state audit. As of April 30, 2015, management
has evaluated the application of these standards to the Fund, and has determined
that no provision for income tax is required in the Fund's financial statements
for uncertain tax positions.

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2014, the
Fund had non-expiring capital loss carryforwards for federal income tax purposes
of $5,759,772.

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, 2014, the Fund had no
net ordinary losses.

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.

Stonebridge, an affiliate of First Trust, serves as the Fund's sub-advisor and
manages the Fund's portfolio subject to First Trust's supervision. Pursuant to
the Investment Management Agreement between the Trust and the Advisor, First
Trust will supervise Stonebridge and its management of the investment of the
Fund's assets and will pay Stonebridge for its services as the Fund's
sub-advisor. First Trust and Stonebridge are equally 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.
Stonebridge receives a sub-advisory fee equal to 0.425% of the average daily net
assets of the Fund less Stonebridge's share of the Fund's expenses. The
Sub-Advisor's fee is paid by the Advisor out of the Advisor's management fee.
First Trust also provides fund reporting services to the Fund for a flat annual
fee in the amount of $9,250, which is covered under the annual unitary
management fee.

The Trust has multiple service agreements with Brown Brothers Harriman & Co.
("BBH"). Under the service agreements, BBH performs custodial, fund accounting,
certain administrative services, and transfer agency services for the Fund. As
custodian, BBH is responsible for custody of the Fund's assets. As fund
accountant and administrator, BBH is responsible for maintaining the books and
records of the Fund's securities and cash. As transfer agent, BBH is responsible
for maintaining shareholder records for the Fund.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated pro rata among each fund in the First Trust Fund
Complex based on 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.


                                                                         Page 19

                      4. PURCHASES AND SALES OF SECURITIES

For the period ended April 30, 2015, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
for the Fund were $91,283,120 and $36,805,505, respectively.

For the period ended April 30, 2015, the cost of in-kind purchases and proceeds
from in-kind sales for the Fund was $57,916,522 and $2,893,416, 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 securities and
other instruments 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 Deposited
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. Purchasers
of Creation Units must pay to BBH, as transfer agent, a creation 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 may increase
or decrease as the Fund's portfolio is adjusted to conform to changes in the
composition of the securities included in the Fund's portfolio and the countries
in which the transaction 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 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 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. LINE OF CREDIT

Effective April 25, 2014, the Trust, First Trust Series Fund and First Trust
Exchange-Traded Fund IV entered into an $80 million Credit Agreement with the
Bank of Nova Scotia ("Scotia") as administrative agent for a group of lenders.
Prior to March 26, 2015, a commitment fee of 0.125% of the daily amount of the
excess of the commitment amount over the outstanding principal balance of the
loans was charged by Scotia. Effective March 26, 2015, the commitment fee was
changed to 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, 2015.

                              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
Funds, for amounts expended to finance activities primarily intended to result
in the sale of Creation Units or to provide investor services. FTP may also use
this amount to compensate securities dealers or other persons that are
Authorized Participants for providing distribution assistance, including
broker-dealer and shareholder support and educational and promotional services.

No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before February 28, 2017.

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 EVENT

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

On May 20, 2015, the Fund declared a distribution of $0.0790 per share to Common
Shareholders of record on May 26, 2015, payable May 29, 2015.


                                                                         Page 21

                              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.

CASH TRANSACTIONS RISK. The Fund may under certain 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.

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.

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
if the Fund invests 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.

DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the
underlying securities 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 securities into depositary receipts and vice versa. Such restrictions may
cause the securities of the underlying issuer to trade at a discount or premium
to the market price of the depositary receipts.

FINANCIAL COMPANY RISK. 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.

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.

             FIRST TRUST PREFERRED SECURITIES AND INCOME ETF (FPE)
                           APRIL 30, 2015 (UNAUDITED)


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. If interest rates rise, the prices of the fixed-rate
instruments held by the Fund may fall.

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 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
effected.

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.
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,
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.

REIT RISK. Investing in REITs involves 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. Fund shareholders indirectly pay REIT
fees and expenses.

BOARD CONSIDERATIONS REGARDING CONTINUATION OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees of the First Trust Exchange-Traded Fund III (the "Trust"),
including the Independent Trustees, unanimously approved the continuation of the
Investment Management Agreement (the "Advisory Agreement") with First Trust
Advisors L.P. (the "Advisor" or "First Trust") on behalf of the First Trust
Preferred Securities and Income 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 Stonebridge Advisors LLC (the "Sub-Advisor"). The Board approved the
continuation of the Agreements for a one-year period ending March 31, 2016, at a
meeting held on March 8-9, 2015. The Board of Trustees determined that the
continuation of the Agreements is in the best interests of the Fund in light of
the extent and quality of services provided and such other matters as the Board
considered to be relevant in the exercise of its reasonable business judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. To assist the Board in its evaluation of the Agreements, the
Independent Trustees received a report from each of the Advisor and the
Sub-Advisor in advance of the Board meeting responding to a request for


                                                                         Page 23

                           APRIL 30, 2015 (UNAUDITED)


information from counsel to the Independent Trustees. The reports, among other
things, outlined the services provided by the Advisor and the Sub-Advisor to the
Fund (including the relevant personnel responsible for these services and their
experience); the unitary fee for the Fund as compared to fees charged to a peer
group of funds (all of which were exchange-traded funds or "ETFs") compiled by
Management Practice Inc. ("MPI"), an independent source (the "MPI Peer Group"),
and as compared to fees charged to other clients of the Advisor with similar
investment objectives and to other ETFs managed by the Advisor; the sub-advisory
fee as compared to fees charged to other clients of the Sub-Advisor with similar
investment objectives; expenses of the Fund compared to expense ratios of the
funds in the MPI Peer Group; the nature of expenses 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 the Advisor and
its affiliates, First Trust Portfolios L.P. ("FTP") and the Sub-Advisor; and a
summary of the Advisor's and the Sub-Advisor's compliance programs. Following
receipt of this information, the Independent Trustees and their counsel met
separately 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 the Advisor 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. The Board
considered that shareholders chose to invest or remain invested in the Fund
knowing that the Advisor and the Sub-Advisor manage the Fund and knowing the
Fund's unitary fee.

In reviewing the Agreements, the Board considered the nature, extent and quality
of services provided by the Advisor and the Sub-Advisor under the Agreements.
The Board considered that, unlike most other ETFs to which First Trust currently
provides management services, the Fund is not designed to track the performance
of an index and the Fund employs an advisor/sub-advisor management structure.
With respect to the Advisory Agreement, the Board considered that the Advisor is
responsible for the overall management and administration of the Fund and
reviewed the services provided by the Advisor to the Fund, including the
oversight of the Sub-Advisor. The Board noted the compliance program that had
been developed by the Advisor and considered that it includes a robust program
for monitoring the Sub-Advisor's compliance with the 1940 Act and the Fund's
investment objective and policies. The Board considered the significant asset
growth of the First Trust Fund Complex (particularly in ETFs) and the Advisor's
concomitant investment in infrastructure and personnel dedicated to the First
Trust funds. The Board noted the background and experience of the Sub-Advisor's
portfolio management team. The Board noted that its familiarity with the
Sub-Advisor is also due to its oversight of four other funds in the First Trust
Fund Complex all or a portion of which are sub-advised by the Sub-Advisor. In
light of the information presented and the considerations made, the Board
concluded that the nature, extent and quality of services provided to the Fund
by the Advisor and the Sub-Advisor under the Agreements have been and are
expected to remain satisfactory and that the Sub-Advisor, under the oversight of
the Advisor, has managed the Fund consistent with its investment objective and
policies.

The Board considered the unitary fee payable by the Fund under the Advisory
Agreement, noting that the Fund pays the Advisor a fee equal to an annual rate
of 0.85% of its average daily net assets and that the Advisor pays the
Sub-Advisor a fee equal to an annual rate of 0.425% of the Fund's average daily
net assets from the fee it receives from the Fund. The Board noted that the
Advisor and Sub-Advisor are equally responsible for the Fund's expenses,
including the cost of transfer agency, custody, fund administration, legal,
audit and other services, but excluding interest, taxes, brokerage commissions
and other expenses connected with the execution of portfolio transactions,
distribution and service fees pursuant to a Rule 12b-1 plan, if any, and
extraordinary expenses. The Board also reviewed data prepared by MPI showing the
unitary fee for the Fund as compared to the advisory fees and expense ratios of
the peer funds in the MPI Peer Group and determined that, because the Fund
charges a unitary fee, expense ratios were the most relevant data point. Based
on the information provided, the Board noted that the unitary fee for the Fund
was above the median total (net) expense ratio of the peer funds in the MPI Peer
Group. The Independent Trustees discussed with representatives of the Advisor
and independent counsel limitations in creating peer groups for actively-managed
ETFs and different business models that affect the pricing of services among ETF
sponsors. The Board noted that all of the funds in the MPI Peer Group were
larger than the Fund - three significantly so. The Board also noted that none of
the peer funds had sub-advisors nor were any of the peer funds actively managed.
The Board took these limitation and differences into account in considering the
MPI data. 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. The Board also
considered information provided by the Sub-Advisor as to the fees it charges for
investment advisory services provided to clients with similar investments, and
noted both that the fee rate was similar and that the Sub-Advisor does not share
in the expenses of the other funds.

The Board considered performance information for the Fund, noting that the
performance information included the Fund's quarterly performance report, which
is part of the process that the Board has established for monitoring the Fund's
performance on an ongoing basis. The Board determined that this process
continues to be effective for reviewing the Fund's performance. The Board
reviewed data prepared by MPI comparing the Fund's performance to the MPI Peer
Group and to broad-based benchmarks and a blended benchmark. The Board also
considered an analysis from the Sub-Advisor regarding the Fund's performance,
including a comparison to its blended benchmark and the MPI Peer Group for the
one year period ended December 31, 2014 and since its inception on February 11,
2013, which also addressed differences between the Fund and the peer funds, as
well as conditions in the preferred securities market during those times.

                           APRIL 30, 2015 (UNAUDITED)


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

The Board noted that the Advisor has made and continues to make significant
investments in personnel and infrastructure and considered whether the unitary
fee reflects any economies of scale for the benefit of shareholders. 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 the unitary fee
structure provides a level of certainty in expenses for the Fund. The Board also
considered the costs of the services provided and any profits realized by the
Advisor and the Sub-Advisor from serving as investment advisors to the Fund for
the period ended December 31, 2014, as well as product-line profitability data
for the same period, as set forth in the materials provided to the Board. Based
on the information provided, the Board noted that the Fund was not profitable
for either the Advisor or the Sub-Advisor for calendar year 2014. The Board
considered that the Advisor had identified as a fall-out benefit to the Advisor
and FTP their exposure to investors and brokers who, in the absence of the Fund,
may have had no dealings with the Advisor or FTP, and noted that the Sub-Advisor
does not utilize soft dollars in connection with its management of the Fund's
portfolio. The Board considered the ownership interest of the Advisor in the
Sub-Advisor and potential fall-out benefits to the Advisor and the Sub-Advisor
from such ownership interest. The Board also considered the Advisor's
compensation for fund reporting services provided to the Fund pursuant to a
separate Fund Reporting Services Agreement, which is paid from the unitary fee.

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

                    FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2015

Dear Shareholders:

Thank you for your investment in First Trust Managed Municipal 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, 2015. Additionally, First Trust compiles the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

U.S. markets, fueled by accelerating growth and an accommodating Federal
Reserve, enjoyed a prosperous year in 2014. However, for the six months covered
by this report, some economic and global factors, including the continued
conflict in the Middle East and a sharp decline in oil prices, created
volatility in the U.S. and global markets. Another factor that has impacted
markets is the fact that many economists are predicting the Federal Reserve will
begin to raise interest rates this year.

As I have written previously, First Trust believes investors should maintain
perspective about the markets and have realistic expectations about their
investments. Markets will always go up and down, but we believe that having a
long-term investment horizon and being invested in quality products can help you
reach your goals.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value the relationship and will continue to focus on our disciplined
investment approach and long-term perspective to help investors reach their
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.

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 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 May 14, 2014 (commencement of
trading) through April 30, 2015. 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.

The First Trust Advisors L.P. ("First Trust") Municipal Securities Team was
formed in September of 2013 and is headed by Tom Futrell, CFA and Johnathan
Wilhelm who serve as senior portfolio managers of the First Trust Managed
Municipal ETF (the "Fund"). Messrs. Futrell and Wilhelm have a combined 50+
years of investment experience and prior to joining First Trust, served as

FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2015 (UNAUDITED)

As a shareholder of First Trust Managed Municipal 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, 2015.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on each Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
each Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the 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 MANAGED MUNICIPAL ETF (FMB)
PORTFOLIO OF INVESTMENTS (CONTINUED)

(a)   Zero coupon bond.

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended (the "1933 Act"), and may be resold in transactions
      exempt from registration, normally to qualified institutional buyers.
      Pursuant to procedures adopted by the Trust's Board of Trustees, this
      security has been determined to be liquid by First Trust Advisors L.P.,
      the Fund's advisor. 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, 2015, securities noted as such
      amounted to $523,035 or 2.25% of net assets.

(c)   The following table provides a listing of those entities that have either
      issued, guaranteed, backed or otherwise enhanced the credit quality of
      more than 5% of the net assets of the Fund. In instances where the entity
      has guaranteed, backed or otherwise enhanced the credit quality of a
      security, it is not primarily responsible for the issuer's obligations but
      may be called upon to satisfy the issuer's obligations.

                Assured Guaranty Municipal Corp.              5.5%

(d)   Security has a mandatory put by the holder. Maturity date reflects such
      put.

(e)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2015, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $511,548 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $14,734.

                    FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
                           APRIL 30, 2015 (UNAUDITED)


                               1. ORGANIZATION

First Trust Exchange-Traded Fund III (the "Trust") is a non-diversified open-end
management investment company organized as a Massachusetts business trust on
January 9, 2008, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended (the "1940 Act").

The Trust consists of four funds that are currently offering shares. This report
covers the First Trust Managed Municipal ETF (the "Fund"), which trades under
the ticker FMB on The NASDAQ(R) 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 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 primary investment objective of the Fund is to generate current income that
is exempt from regular federal income taxes and its secondary objective is
long-term capital appreciation. Under normal market conditions, the Fund seeks
to achieve its investment objectives by investing at least 80% of its net assets
(including investment borrowings) in municipal debt securities that pay interest
that is exempt from regular federal income taxes. There can be no assurance that
the Fund will achieve its investment objectives. The Fund may not be appropriate
for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

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

A. PORTFOLIO VALUATION

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

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

      Municipal securities and other debt securities are fair valued on the
      basis of fair 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.

      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:


                                                                         Page 15

                    FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
                           APRIL 30, 2015 (UNAUDITED)


      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 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 (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; and

      10)   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

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, 2015, is

                    FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
                           APRIL 30, 2015 (UNAUDITED)


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 have 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.

The tax character of distributions paid during the fiscal period ended October
31, 2014 was as follows:


Distributions paid from:
Ordinary income....................................         $      8,427
Tax-exempt income..................................              210,334
Return of capital..................................               39,240

As of October 31, 2014, the components of distributable earnings on a tax basis
were as follows:


Undistributed ordinary income......................         $         --
Accumulated capital and other losses...............                   --
Net unrealized appreciation (depreciation).........              463,913

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.

In addition, the Fund intends to invest in such municipal securities to allow it
to pay shareholders "exempt dividends" as defined in the Internal Revenue Code.

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 2014
remains open to federal and state audit. As of April 30, 2015, management has
evaluated the application of these standards to the Fund, and has determined
that no provision for income tax is required in the Fund's financial statements
for uncertain tax positions.

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2014, the
Fund had no non-expiring capital loss carryforwards for federal income tax
purposes.

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 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


                                                                         Page 17

                    FIRST TRUST MANAGED MUNICIPAL ETF (FMB)
                           APRIL 30, 2015 (UNAUDITED)


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. First Trust also provides fund reporting services to the Fund for a flat
annual fee in the amount of $9,250, which is covered under the annual unitary
management fee.

The Trust has multiple service agreements with Brown Brothers Harriman & Co.
("BBH"). Under the service agreements, BBH performs custodial, fund accounting,
certain administrative services, and transfer agency services for the Fund. As
custodian, BBH is responsible for custody of the Fund's assets. As fund
accountant and administrator, BBH is responsible for maintaining the books and
records of the Fund's securities and cash. As transfer agent, BBH is responsible
for maintaining shareholder records for the Fund.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated pro rata among each fund in the First Trust Fund
Complex based on 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, 2015, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
were $14,812,237 and $12,220,315, respectively.

For the six months ended April 30, 2015, the Fund had no in-kind transactions.

                                 5. BORROWINGS

Effective March 26, 2015, the Fund was added to an $80 million Credit Agreement
with The Bank of Nova Scotia ("Scotia") as administrative agent for a group of
lenders. The Credit Agreement is to be used as 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 is charged by Scotia, which First Trust allocates 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 period ended April 30, 2015.

                 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 and
other instruments 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 Deposited
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. Purchasers
of Creation Units must pay to BBH, as transfer agent, a creation 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 Creation Transaction Fee may increase or decrease as the Fund's
portfolio is adjusted to conform to changes in the composition of the securities
included in the Fund's portfolio and the countries in which the transaction
settled. 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, 2015 (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 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 May 15, 2016.

                               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. ADOPTION OF NON-FUNDAMENTAL INVESTMENT POLICY

On March 27, 2015, the Board of Trustees of the Fund approved the adoption of a
non-fundamental investment policy regarding the Fund's ability to invest in
other investment companies (the "Policy"). Pursuant to the Policy, beginning on
or about June 7, 2015, the Fund will not rely on Section 12(d)(1)(F) or
12(d)(1)(G) of the Investment Company Act of 1940, as amended, to invest in
other investment companies.

                              10. SUBSEQUENT EVENT

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

On May 20, 2015, the Fund declared a distribution of $0.115 per share to
shareholders of record on May 26, 2015, payable May 29, 2015.


                                                                         Page 19

                      PROXY VOTING POLICIES AND PROCEDURES

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

the Fund's website located at http://www.ftportfolios.com; and (3) on the
Securities and Exchange Commission's ("SEC") website located at
http://www.sec.gov.

                               PORTFOLIO HOLDINGS

The Trust files its complete schedule of portfolio holdings with the SEC for the
first and third quarters of each fiscal year on Form N-Q. The Trust's Forms N-Q

http://www.ftportfolios.com; (3) on the SEC's website at http://www.sec.gov; and

Washington, DC. Information regarding the operation of the PRR may be obtained
by calling (800) SEC-0330.

                              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.

ALTERNATIVE MINIMUM TAX RISK. The Fund has no limit as to the amount that can be
invested in alternative minimum tax bonds. Therefore, all or a portion of the
Fund's otherwise exempt-interest dividends may be taxable to those shareholders
subject to the federal alternative minimum tax.

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 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.

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. These
securities are issued by issuers that may have 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. In
general, high yield securities may have a greater risk of default than other
types of securities.

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
securities in the Fund will decline because of rising market interest rates.
When interest rates change, the values of longer duration debt securities
usually change more than the values of shorter duration debt securities.

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.

                           APRIL 30, 2015 (UNAUDITED)


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 bond
prices. Also, certain of these factors may affect the liquidity of the bonds in
the Fund's portfolio and make it more difficult for the Fund to sell them.
Overall security values could decline generally or could underperform other
investments.

MUNICIPAL LEASE OBLIGATIONS RISK. Participation interests in municipal leases
pose special risks because many leases and contracts contain "non-appropriation"
clauses that provide that the governmental issuer has no obligation to make
future payments under the lease or contract unless money is appropriated for
this purpose by the appropriate legislative body.

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
Investment Company Act of 1940 Act (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 concentrated in certain issuers.

POLITICAL AND ECONOMIC RISKS. The values of Municipal Securities held by the
Fund may be adversely affected by local political and economic conditions and
developments. Adverse conditions in an industry significant to a local economy
could have a correspondingly adverse effect on the financial condition of local
issuers.

TAX RISK. Interest income from Municipal Securities is normally not subject to
regular federal income tax, but income from Municipal Securities held by the
Fund could be declared taxable because of, among other things, unfavorable
changes in tax laws, adverse interpretations by the Internal Revenue Service or
state tax authorities or noncompliant conduct of a bond issuer. Consequently,
the attractiveness of Municipal Securities in relation to other investment
alternatives is affected by changes in federal income tax rates or changes in
the tax-exempt status of interest income from Municipal Securities.

ZERO COUPON BONDS RISK. Zero coupon bonds do not pay interest on a current basis
and may be highly volatile as interest rates rise or fall. In addition, while
such bonds generate income for purposes of generally accepted accounting
standards, they do not generate cash flow and thus could cause the Fund to be
forced to liquidate securities at an inopportune time in order to distribute
cash, as required by tax laws.


                                                                         Page 21

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

                    FIRST TRUST LONG/SHORT EQUITY ETF (FTLS)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2015

Dear Shareholders:

Thank you for your investment in First Trust Long/Short Equity 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, 2015. Additionally, First Trust compiles the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

U.S. markets, fueled by accelerating growth and an accommodating Federal
Reserve, enjoyed a prosperous year in 2014. However, for the six months covered
by this report, some economic and global factors, including the continued
conflict in the Middle East and a sharp decline in oil prices, created
volatility in the U.S. and global markets. Another factor that has impacted
markets is the fact that many economists are predicting the Federal Reserve will
begin to raise interest rates this year.

As I have written previously, First Trust believes investors should maintain
perspective about the markets and have realistic expectations about their
investments. Markets will always go up and down, but we believe that having a
long-term investment horizon and being invested in quality products can help you
reach your goals.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value the relationship and will continue to focus on our disciplined
investment approach and long-term perspective to help investors reach their
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 LONG/SHORT EQUITY ETF (FTLS)

The investment objective of First Trust Long/Short Equity ETF (the "Fund") is to
seek to provide investors with long-term total return. The Fund pursued its
objective by establishing long and short positions in a portfolio of Equity
Securities (as defined below). Under normal circumstances, at least 80% of the
Fund's net assets (plus the amount of any borrowing for investment purposes)
will be exposed to U.S. exchange-listed equity securities of U.S. and foreign
companies by investing in such securities directly and/or in U.S.
exchange-traded funds ("ETFs") that provide exposure to such securities. The
securities of the companies and ETFs in which the Fund will invest are referred
to collectively as "Equity Securities." The Equity Securities held by the Fund
may include U.S. exchange-listed equity securities of foreign issuers, as well
as investments in the equity securities of foreign issuers that are in the form
of depositary receipts.

The Fund takes long and short positions in Equity Securities. As opposed to
taking long positions in which an investor seeks to profit from increases in the
price of a security, short selling is a technique that will be used by the Fund
to try and profit from the falling price of a security. Short selling involves
selling a security that has been borrowed from a third party with the intention
of buying an identical security back at a later date to return to that third
party.

Having both long and short positions in an equity security portfolio is a common
way to create returns that are independent of market moves. One advantage of a
long and short portfolio is that the long and short positions may offset one
another in a manner that results in a lower net exposure to the direction of the
market. In addition, cash balances arising from the use of short selling
typically will be held in money market instruments.

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.

was at a discount or premium to the daily NAV. The following tables are for
comparative purposes only and represent the period September 9, 2014
(commencement of trading) through April 30, 2015. 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

FIRST TRUST LONG/SHORT EQUITY ETF (FTLS)
UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2015 (UNAUDITED)


As a shareholder of First Trust Long/Short Equity 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, 2015.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the following table provides information about hypothetical
account values and hypothetical expenses based on the Fund's actual expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return. The hypothetical account values and expenses may not
be used to estimate the actual ending account balance or expenses you paid for
the period. You may use this information to compare the ongoing costs of
investing in the Fund and other funds. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs such as brokerage
commissions. Therefore, the second line in the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

                    FIRST TRUST LONG/SHORT EQUITY ETF (FTLS)
                           APRIL 30, 2015 (UNAUDITED)


                                1. ORGANIZATION

First Trust Exchange-Traded Fund III (the "Trust") is a non-diversified open-end
management investment company organized as a Massachusetts business trust on
January 9, 2008, 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 four funds that are offering shares. This report
covers the First Trust Long/Short Equity ETF (the "Fund"), which trades under
the ticker "FTLS" on the NYSE Arca, Inc. 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 securities in which
the Fund invests or for cash or, in certain circumstances, a combination of
both. Except when aggregated in Creation Units, the shares are not redeemable
securities of the Fund.

The investment objective of the Fund is to seek to provide investors with
long-term total return. The Fund pursues its investment objective by
establishing long and short positions in a portfolio of equity securities. Under
normal circumstances, at least 80% of the Fund's net assets (plus the amount of
any borrowing for investment purposes) will be exposed to U.S. exchange-listed
equity securities of U.S. and foreign companies by investing in such securities
directly and/or in U.S. exchange-traded funds ("ETFs") that provide exposure to
such securities. The equity securities held by the Fund may include U.S.
exchange-listed equity securities of foreign issuers, as well as investments in
the equity securities of foreign issuers that are in the form of depositary
receipts. 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 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:

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding The NASDAQ(R) 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 one or 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), for which a pricing service is unable to provide a market
price; securities whose trading has been formally suspended; a


                                                                         Page 17

                    FIRST TRUST LONG/SHORT EQUITY ETF (FTLS)
                           APRIL 30, 2015 (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.

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, 2015, 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 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 are not
known until after the REIT's 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. 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

                           APRIL 30, 2015 (UNAUDITED)


costs of borrowing the securities. The Fund will pay 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 in the market or otherwise 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 that 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 ("Pershing") for the purpose of
purchasing 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. Restricted cash in the amount of $2,837,371, as shown on
the Statement of Assets and Liabilities, is associated with collateral at the
broker as of April 30, 2015.

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 have 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.

The tax character of distributions paid during the fiscal period ended October
31, 2014 was as follows:

Distributions paid from:
Ordinary income....................................    $        1,620

As of October 31, 2014, the components of distributable earnings on a tax basis
to the Fund were as follows:

Undistributed ordinary income......................    $        4,502
Accumulated capital and other losses...............               218
Net unrealized appreciation (depreciation).........            49,099

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 or state income taxes. However, due to the timing and
amount of distributions, the Fund may be subject to an excise tax of 4% of the
amount by which approximately 98% of the Fund's taxable income exceeds the
distributions from such taxable income for the calendar year.

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. The taxable year ended 2014
remains open to federal and state audit. As of April 30, 2015, 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.

Net capital losses may be carried forward indefinitely, and their character is
retained as short-term and/or long-term losses. At October 31, 2014, the Fund
had no net capital losses 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.

F. EXPENSES

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


                                                                         Page 19

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,
dividend expenses on investments sold short, 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. First Trust also provides fund reporting
services to the Fund for a flat annual fee in the amount of $9,250, which is
covered under the annual unitary management fee.

The Trust has multiple service agreements with Brown Brothers Harriman & Co.
("BBH"). Under the service agreements, BBH performs custodial, fund accounting,
certain administrative services, and transfer agency services for the Fund. As
custodian, BBH is responsible for custody of the Fund's assets. As fund
accountant and administrator, BBH is responsible for maintaining the books and
records of the Fund's securities and cash. As transfer agent, BBH is responsible
for maintaining shareholder records for the Fund.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated pro rata among each fund in the First Trust Fund
Complex based on 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 period ended April 30, 2015, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
for the Fund were $6,123,334 and $6,218,151, respectively. The cost of purchases
to cover short sales and the proceeds of short sales were $2,290,735 and
$4,538,894, respectively.

For the period ended April 30, 2015, the cost of in-kind purchases and proceeds
from in-kind sales for the Fund was $16,097,934 and $4,859,907, 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 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 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. Purchasers of Creation Units must
pay to BBH, as transfer agent, a creation 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 may increase or decrease
as the Fund's portfolio is adjusted to conform to changes in the composition of
the securities included in the Fund's portfolio and the countries in which the
transaction settled. The Creation Transaction fee is currently $550. The price
for each Creation Unit will equal the daily NAV per

                           APRIL 30, 2015 (UNAUDITED)


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 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 $550. 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 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 September 4, 2016.

                               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. ADOPTION OF NON-FUNDAMENTAL INVESTMENT POLICY

On March 27, 2015, the Board of Trustees of the Fund approved the adoption of a
non-fundamental investment policy regarding the Fund's ability to invest in
other investment companies (the "Policy"). Pursuant to the Policy, beginning on
or about June 7, 2015, the Fund will not rely on Section 12(d)(1)(F) or
12(d)(1)(G) of the Investment Company Act of 1940, as amended, to invest in
other investment companies.

                              9. 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.

the Fund's website located at http://www.ftportfolios.com; and (3) on the
Securities and Exchange Commission's ("SEC") website located at
http://www.sec.gov.

                               PORTFOLIO HOLDINGS

The Trust files its complete schedule of portfolio holdings with the SEC for the
first and third quarters of each fiscal year on Form N-Q. The Trust's Forms N-Q

                              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.

CASH TRANSACTIONS RISK. The Fund may, under certain circumstances, affect a
portion of creations and redemptions for cash, rather than in-kind securities,
particularly for the puts and call options in which the Fund invests. 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 affect 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.

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.

DERIVATIVES RISK. The use of futures 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.

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.

ETF RISK. The Fund may invest in the shares of other ETFs, and therefore, the
Fund's investment performance and risks may be related to the investment
performance and risks of the underlying ETFs. In general, as a shareholder in
other ETFs, the Fund bears its ratable share of the underlying ETF's expenses,
and would be subject to duplicative expenses to the extent the Fund invests in
other ETFs.

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.

                           APRIL 30, 2015 (UNAUDITED)


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.

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.

NON-U.S. SECURITIES RISK. The Fund holds non-U.S. securities that are either
directly listed on a U.S. securities exchange or in the form of depositary
receipts. 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.

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 of a security 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.


                                                                         Page 23

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

          FIRST TRUST EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2015

Dear Shareholders:

Thank you for your investment in First Trust Emerging Markets Local Currency
Bond 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, 2015. Additionally, First Trust compiles the
Fund's financial statements for you to review. We encourage you to read this
report and discuss it with your financial advisor.

U.S. markets, fueled by accelerating growth and an accommodating Federal
Reserve, enjoyed a prosperous year in 2014. However, for the six months covered
by this report, there was only modest global economic growth. Several
geopolitical events, including trade sanctions between the U.S./Europe and
Russia due to its conflict with Ukraine, low interest rate levels on government
bonds in most developed nations, and the absence of any significant inflationary
pressures, weighed on global markets.

As I have written previously, First Trust believes investors should maintain
perspective about the markets and have realistic expectations about their
investments. Markets will always go up and down, but we believe that having a
long-term investment horizon and being invested in quality products can help you
reach your goals.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value the relationship and will continue to focus on our disciplined
investment approach and long-term perspective to help investors reach their
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 EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)

First Trust Emerging Markets Local Currency Bond ETF (the "Fund") seeks maximum
total return and current income. The Fund lists and principally trades its
shares on The NASDAQ Stock Market LLC ("NASDAQ") under the ticker symbol "FEMB."
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 bonds, notes and bills issued or guaranteed by entities in
emerging market countries (collectively, "Bonds") that are denominated in the
local currency of the issuer.

In implementing the Fund's investment strategy, First Trust Global Portfolios
Ltd. (the "Sub-Advisor") will seek to provide current income and enhance
capital, while minimizing volatility. The Sub-Advisor will continually review
fundamental economic and structural themes that impact long and medium term
asset returns in emerging markets. The Sub-Advisor will also consider
shorter-term market drivers such as valuations, liquidity conditions and
sentiment to determine the appropriate positioning of the Fund's investments.
The Sub-Advisor will adjust the portfolio's country allocations, duration and
individual security positioning to reflect what the Sub-Advisor believes to be
the most attractive opportunities on a continuous basis.

The Fund may invest in foreign currencies and derivative instruments, including
exchange-listed futures contracts, exchange-listed options, exchange-listed
options on futures contracts, forward currency contracts, non-deliverable
forward currency contracts and exchange-listed currency options. The Fund will
use foreign currencies and derivative instruments primarily to hedge interest
rate risk and actively manage interest rate exposure and to hedge foreign
currency risk and actively manage foreign currency exposure. The Fund may also
use derivative instruments to enhance returns, as a substitue for, or to gain
exposure to, a position in an underlying asset, to reduce transaction costs, to
maintain full market exposure, to manage cash flows or to preserve capital.

Total returns for the periods 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 returns assume that all distributions have been
reinvested in the Fund at NAV and Market Price, respectively.

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

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

FREQUENCY DISTRIBUTION OF DISCOUNTS AND PREMIUMS
BID/ASK MIDPOINT VS. NAV THROUGH APRIL 30, 2015

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, 2015. 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.

                               INVESTMENT ADVISOR

FIRST TRUST EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)
UNDERSTANDING YOUR FUND EXPENSES
APRIL 30, 2015 (UNAUDITED)


As a shareholder of First Trust Emerging Markets Local Currency Bond 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, 2015.

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 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.

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

          FIRST TRUST EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)
                           APRIL 30, 2015 (UNAUDITED)


                                 1. ORGANIZATION

First Trust Exchange-Traded Fund III (the "Trust") is a non-diversified open-end
management investment company organized as a Massachusetts business trust on
January 9, 2008, 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 four funds that are offering shares. This report
covers the First Trust Emerging Markets Local Currency Bond ETF (the "Fund"),
which trades under the ticker FEMB on The NASDAQ(R) 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 securities in which the Fund invests or for cash or, in
certain circumstances, a combination of both. Except when aggregated in Creation
Units, the shares are not redeemable securities of the Fund.

The Fund is an actively managed exchange-traded fund. The investment objective
of the Fund is to seek maximum total return and current income. 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
bonds, notes, bills, certificates of deposit, time deposits, commercial paper
and loans issued by issuers in emerging market countries that are denominated in
the local currency of the issuer. The Fund may not be appropriate for all
investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

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 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:

      Bonds, notes and other debt securities are fair valued on the basis of
      valuations provided by dealers who make markets in such securities or by
      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.

      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


                                                                         Page 15

                           APRIL 30, 2015 (UNAUDITED)


      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.

      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.

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, or economic
            data relating to the country of issue;

      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, or the financial condition
            of the country of issue;

      5)    the credit quality and cash flow of the issuer, or country of issue,
            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 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 governmental
            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.

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).

          FIRST TRUST EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)
                           APRIL 30, 2015 (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, 2015, 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. Amortization of premiums and accretion of
discounts are recorded using the effective interest method.

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. The change in
unrealized appreciation (depreciation) is included in "Net change in unrealized
appreciation (depreciation) on forward foreign currency contracts" on the
Statement of Operations. 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, 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.

D. OFFSETTING ON THE STATEMENT OF ASSETS AND LIABILITIES

Accounting Standards Update No. 2011-11 "Disclosures about Offsetting Assets and
Liabilities" ("ASU 2011-11") requires entities to disclose both gross and net
information about instruments and transactions eligible for offset on the
Statement of Assets and Liabilities, and disclose instruments and transactions
subject to master netting or similar agreements. These disclosure requirements
are intended to help investors and other financial statement users better assess
the effect or potential effect of offsetting arrangements on a fund's financial
position. In addition, Accounting Standards Update No. 2013-1 "Clarifying the
Scope of Offsetting Assets and Liabilities" ("ASU 2013-1"), specifies exactly
which transactions are subject to offsetting disclosures. The scope of the
disclosure requirements is limited to derivative instruments, repurchase
agreements and reverse repurchase agreements, and securities borrowing and
securities lending transactions.

For financial reporting purposes, the Fund does not offset financial assets and
financial liabilities that are subject to master netting arrangements ("MNAs")
or similar agreements on the Statement of Assets and Liabilities. MNAs provide
the right, in the event of default (including bankruptcy and insolvency), for
the non-defaulting counterparty to liquidate the collateral and calculate the
net exposure to the defaulting party or request additional collateral.

At April 30, 2015, derivative assets and liabilities (by type) on a gross basis
are as follows:



                                                                                          Gross Amounts not Offset in

*The respective counterparties for each contract are disclosed on the Forward
Foreign Currency Contracts table in the Portfolio of Investments.

E. 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. 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.

F. 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 have 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.

G. 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, 2015, management
has evaluated the application of these standards to the Fund, and has determined
that no provision for income tax is required in the Fund's financial statements
for uncertain tax positions.

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

H. EXPENSES

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

                           APRIL 30, 2015 (UNAUDITED)


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 Trust, on behalf of the Fund, and First Trust have retained First Trust
Global Portfolios Ltd. ("First Trust Global" or the "Sub-Advisor"), an affiliate
of First Trust, to serve as investment sub-advisor. In this capacity, First
Trust Global is responsible for the selection and ongoing monitoring of the
securities in the Fund's investment portfolio. First Trust is paid an annual
unitary management fee of 0.85% of the Fund's average daily net assets. First
Trust is responsible for the expenses of the Fund including the cost of transfer
agency, custody, fund administration, legal, audit and other services, including
any compensation to Trustees, and excluding Rule 12b-1 distribution and service
fees, if any, brokerage expenses, taxes, interest, acquired fund fees and
expenses, and extraordinary expenses, which are paid by each respective Fund.
First Trust also provides fund reporting services to the Fund for a flat annual
fee in the amount of $9,250, which is covered under the annual unitary
management fee.

The Trust has multiple service agreements with 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 pro rata among each fund in the First Trust Fund
Complex based on 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 period ended April 30, 2015, the cost of purchases and proceeds from
sales of investments, excluding short-term investments and in-kind transactions,
for the Fund were $5,720,741 and $1,089,197, respectively.

For the period ended April 30, 2015, the Fund had no in-kind transactions.

respectively.

                 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 and
other instruments 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 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. Purchasers of Creation Units must
pay to BBH, as transfer agent, a creation 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
Creation Transaction Fee may increase or decrease as the Fund's portfolio is
adjusted to conform to changes in the composition of the securities included in
the Fund's portfolio and the countries in which the transaction settled. 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 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 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. LINE OF CREDIT

Effective March 26, 2015, the Fund was added to an $80 million Credit Agreement
with the Bank of Nova Scotia ("Scotia") as administrative agent for a group of
lenders. The Credit Agreement is to be used as 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 is charged by Scotia, which First Trust allocates 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 period ended April 30, 2015.

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

No 12b-1 fees are currently paid by the Fund, and pursuant to a contractual
arrangement, no 12b-1 fees will be paid any time before October 10, 2016.

                               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. ADOPTION OF NON-FUNDAMENTAL INVESTMENT POLICY

On March 27, 2015, the Board of Trustees of the Fund approved the adoption of a
non-fundamental investment policy regarding the Fund's ability to invest in
other investment companies (the "Policy"). Pursuant to the Policy, beginning on
or about June 7, 2015, the Fund will not rely on Section 12(d)(1)(F) or
12(d)(1)(G) of the 1940 Act, as amended, to invest in other investment
companies.

                              11. SUBSEQUENT EVENT

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

On May 20, 2015, the Fund declared a distribution of $0.20 per share to
shareholders of record on May 26, 2015, payable May 29, 2015.


                                                                         Page 21

first and third quarters of each fiscal year on Form N-Q. The Trust's Forms N-Q

                              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.

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 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.

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 EXCHANGE RATE RISK. The Fund holds 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.

CURRENCY RISK. Because the Fund's net asset value is determined on the basis of
U.S. dollars and the Fund invests in non-U.S. dollar-denominated 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 may hedge certain of its non-U.S. dollar holdings.

DERIVATIVES RISK. The use of options, futures contracts, forward contracts and
other 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 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.

EMERGING MARKETS RISK. Investments in securities and instruments traded in
developing or emerging markets or that provide exposure to such securities or
markets, can involve additional risks relating to political, economic, or
regulatory conditions not associated with investments in U.S. securities and
instruments or investments in more developed international markets. Emerging
market governments may, without prior warning, impose capital controls on the
ability to transfer currency, securities or other assets. The Fund's ability to
access certain developing or emerging markets also may be limited due to a
variety of factors, including currency convertibility issues. Such conditions
may impact the ability of the Fund to buy, sell or otherwise transfer
securities, cause the Fund's returns to differ from those available to domestic
investors, adversely affect the trading market and price for Fund shares, and
cause the Fund to decline in value.

GLOBAL DEPOSITARY NOTES RISK. Any distributions paid to the holders of GDNs are
usually subject to a fee charged by the depositary bank. Holders of GDNs may
have limited rights, and investment restrictions in certain countries may
adversely impact the value of GDNs because such restrictions may limit the
ability to convert the Bonds into GDNs and vice versa.

                           APRIL 30, 2015 (UNAUDITED)


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. These
securities are issued by issuers that may have narrowly focused operations
and/or other impediments to the timely payment of periodic interest and
principal at maturity. If the global or local 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
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 bond
prices. Also, certain of these factors may affect the liquidity of the Bonds in
the Fund's portfolio and make it more difficult for the Fund to sell them.
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.

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.

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.

SOVEREIGN DEBT RISK. Investments in sovereign bonds 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 availability of sufficient
foreign exchange on the date a payment is due; 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 bonds 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. In times of economic uncertainty, the prices of these
securities may be more volatile than those of corporate debt obligations or of
other government debt obligations.


                                                                         Page 23

          FIRST TRUST EMERGING MARKETS LOCAL CURRENCY BOND ETF (FEMB)
                           APRIL 30, 2015 (UNAUDITED)


BOARD CONSIDERATIONS REGARDING APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

The Board of Trustees of the First Trust Exchange-Traded Fund III (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 Emerging Markets
Local Currency Bond 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 First
Trust Global Portfolios Ltd. (the "Sub-Advisor"), for an initial two-year term
at a meeting held on September 15, 2014. 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 affiliates, First Trust
Portfolios L.P. ("FTP") and the Sub-Advisor; and a summary of the Advisor's and
Sub-Advisor's compliance programs. 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 arrangement 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.
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 objectives 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 the two portfolio managers of the
Sub-Advisor, and were able to ask questions about the Sub-Advisor and the
Sub-Advisor's proposed investment strategies for the Fund. 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 0.85% 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 40% 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, but excluding the
fee payments under the Advisory Agreement, interest, taxes, brokerage
commissions and other expenses connected with the execution of portfolio
transactions, distribution and service fees pursuant to a Rule 12b-1 plan, if
any, and extraordinary expenses. The Board reviewed information provided by
Management Practice Inc. ("MPI") and Lipper Inc. ("Lipper"), independent
sources, 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. The
Board noted that the Fund's expense ratio under its proposed unitary fee was
above the median expense ratio of its Lipper and First Trust peer groups and
equal to 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 that the Advisor and Sub-Advisor provide investment
advisory

and sub-advisory services, respectively, to First Trust Strategic Income ETF
("FDIV"), and the portion of FDIV that is managed by the Sub-Advisor has a
similar investment strategy as the Fund's, for which the Sub-Advisor receives a
sub-advisory fee at the same rate. 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 fall-out benefits described by the Advisor that may be realized from
its and FTP's relationship with the Fund, including First Trust's compensation
for fund reporting services pursuant to a separate Fund Reporting Services
Agreement, which would be included under the unitary fee. The Board considered
fall-out benefits described by the Sub-Adviser and noted that the Sub-Advisor
would not utilize soft dollars in connection with its management of the Fund's
portfolio. The Board also considered the affiliations between First Trust and
the Sub-Advisor and noted the services provided by the Sub-Advisor to certain
First Trust products in Europe.

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.
