                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS

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

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

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objectives. The
Fund is subject to market risk, which is the possibility that the market values
of securities owned by the Fund will decline and that the value of the Fund's
shares may therefore be less than what you paid for them. Accordingly, you can
lose money by investing in the Fund. See "Risk Considerations" in the Notes to
Financial Statements 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 common share price will fluctuate and Fund shares,
when sold, may be worth more or less than their original cost.

                            HOW TO READ THIS REPORT

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

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

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

SHAREHOLDER LETTER

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                  SEMI-ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                 APRIL 30, 2013

Dear Shareholders:

I am pleased to present you with the semi-annual report for your investment in
First Trust High Income Long/Short Fund (the "Fund").

The report you hold contains detailed information about your investment; a
portfolio commentary from the Fund's management team that provides a recap of
the period; a performance analysis and a market and Fund outlook. Additionally,
you will find the Fund's financial statements for the period this report covers.
I encourage you to read this document and discuss it with your financial
advisor. A successful investor is also typically a knowledgeable one, as we have
found to be the case at First Trust Advisors L.P. ("First Trust").

The six months covered by this report have been positive for the U.S. markets.
In fact, the S&P 500 Index, as measured on a total return basis, rose 14% during
the period and many economists and investors have felt positive about the
current market environment. Of course, past performance can never be an
indicator of future performance. As I have written many times, however, First
Trust believes that staying invested in quality products through up and down
markets and having a long-term horizon can help investors reach their financial
goals.

As you know, First Trust offers a variety of products that we believe could fit
many financial plans to help investors seeking long-term investment success. We
encourage you to talk to your advisor about the other investments First Trust
offers that might also fit your financial goals and to discuss those goals with
your advisor regularly so that he or she can help keep you on track.

First Trust will continue to make available up-to-date information about your
investments so you and your financial advisor are current on any First Trust
investments you own. We value our relationship with you, and thank you for the
opportunity to assist you in achieving your financial goals. I look forward to
the remainder of 2013 and to the next edition of your Fund's report.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees of First Trust High Income Long/Short Fund and
Chief Executive Officer of First Trust Advisors L.P.

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND - FSD
                               SEMI-ANNUAL REPORT
                                 APRIL 30, 2013

                                  SUB-ADVISOR

MacKay Shields LLC ("MacKay Shields" or the "Sub-Advisor") is a registered
investment adviser founded in 1938, and is Sub-Advisor to First Trust High
Income Long/Short Fund (the "Fund"). The Fund trades under the ticker symbol FSD
on the New York Stock Exchange. As of April 30, 2013, MacKay Shields had
approximately $78.8 billion in assets under management.

FIRST TRUST HIGH INCOME LONG/SHORT FUND
The Fund's primary investment objective is to provide current income. As a
secondary objective, the Fund seeks capital appreciation. The Fund is designed
to give investors a portfolio for varying market cycles and economic conditions.
In an expanding economy, the strategy of buying U.S. and foreign (including
emerging markets) high-yield corporate securities that are rated below
investment-grade is designed to generate monthly income and capital appreciation
(total return over the long term). However, if the market takes a downturn, the
"short" strategy of having sold borrowed securities that the Global Fixed-Income
Division of MacKay Shields believes could decline in price, may help lessen the
impact of a significant net asset value ("NAV") decline.

MARKET RECAP

This report covers the Fund for the six-month period ending April 30, 2013.

Risk assets were nicely rewarded during the past six months due to the overall
positive tone within the macroeconomic environment. International equities were
the top performer for the period, with the MSCI EAFE Index up 17.18%,
benefitting from the reduced anxieties surrounding the Europe debt crisis. U.S.
equities closely followed; the Russell 2000 Index rose 16.58% and the S&P 500
Index returned 14.42%. High yield corporate bonds, as measured by the Merrill
Lynch High Yield Master II Constrained Index, gained 7.26%, while U.S.
investment-grade corporate bonds only rose 1.49%, according to Barclays. The
10-year Treasury also modestly returned 1.53%, while its yield started and ended
the period at 1.68%.

Reflecting back on the fourth quarter of 2012, market participants were focused
on the impending U.S. "fiscal cliff." These negotiations dominated headlines in
November and December, and markets clearly expected that a resolution would
eventually unfold. As the deadline neared, the markets became somewhat more
volatile, but at the final hour, predictably, a near-term solution was agreed to
and finalized on January 1, 2013. Investor risk appetites were reinvigorated in
the first quarter following this eleventh hour resolution. The agreement to
moderately tighten fiscal policy removed a significant market overhang whereby
investors initially feared that widespread tax hikes would stifle new
investments, consumer spending and growth opportunities. The next obstacle that
was cleared was passage of the $1.2 billion sequestration. It was believed these
budget cuts, if unaltered, could trim as much as 0.50% from GDP. The U.S. dollar
strengthened against most currencies due to a combination of a strengthening
U.S. economy and resolution to the above-mentioned concerns.

The U.S. macro picture maintained its slow growth posture. Consumer spending,
employment, residential investment and capital expenditures are expanding, but
at a moderate rate. The residential housing market continued to be a clear
bright spot in the recovery with both new and existing sales activity being
fairly robust. The improvement has led to a slight pick-up in new supply as
brisk sales, higher prices, low mortgage rates and an improving labor market
have all incentivized mobility across the U.S. residential housing market.
Supporting consumer confidence and spending behavior was a release that U.S.
household net worth was at its highest level since 2007, buoyed in large part by
the recent rise in housing prices and the performance of the stock market, which
officially erased the losses of the 2008 downturn. Meanwhile, inflation remains
in check with core CPI, which excludes the more volatile food and energy
components, coming in at 2.0% year-over-year during the first quarter. Inflation
is still below the Fed's stated threshold of 2.5%, which represents the level
that could prompt tightening in monetary policy. The Federal Reserve reaffirmed
its pledge to keep monetary policy accommodative while remaining committed to
balance sheet expansion. This statement proved critical as minutes to a previous
Federal Open Market Committee meeting signaled dissension among some of the Fed
governors, who questioned the continuation of the current quantitative easing
program after 2013.

We were reminded during the period that Europe continued to be a challenge. Much
of the Eurozone remains entrenched in a deep recession with economic activity
contracting across the board and unemployment rising to staggering levels in
some countries. Markets did not react favorably to Troika(1) demands that Cyprus
impose a levy on all bank deposits as a precondition to receiving bailout funds.
In the end, the levy was scrapped and a deal was announced that would split the
island nation's largest bank, Laiki Bank, into a "good" bank and "bad" bank. The
assets associated with the "good" bank would be rolled into the Bank of Cyprus
where all uninsured deposits would remain frozen. Furthermore, all uninsured
depositors, or account balances above 100,000 euros, would receive a haircut,
along with the senior creditors. In all likelihood, all unsecured creditors and
equity holders of the bank will see their interests wiped out. While concerns
seem under control, many fear that this could be a template for future bank
bailouts and that such fears could prompt capital flight from the peripheral
euro economies. Additionally, following several weeks since the Italian
elections failed to produce a government, a new prime minister--left-leaning
Enrico Letta--was finally elected in April. The new prime minister was tasked
with lifting Italy out of a debilitating economic recession and improving its
electoral system to prevent similar political instability. Italy, like some of
its European Union peers, is an example of the difficulty in balancing austerity
and pro-growth reforms. The markets, however, welcomed the re-election with
10-year Italian government bond yields plummeting on renewed investor
confidence. Government bond yields in Spain and Portugal also rallied. Despite
the economic hardships, we maintain our view that the European Union will remain
intact and not create a "left tail" (defined as an investment's most extreme
downside performance) event as both the political and economic costs would be
far too expensive to absorb.

1     Troika represents the three organizations which have the most power over
      Greece's financial future: the European Commission (EC), the International
      Monetary Fund (IMF), and the European Central Bank (ECB).

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

Manufacturing activity in China slipped and equities retreated as the government
looked to balance growth and inflation risks. The rapid rise in residential
housing prices has been of particular concern to officials, and recent
discussions have taken place with respect to the enforcement of property curbs
that would reign in this growth. Tensions on the Korean peninsula were renewed
late in the first quarter with war rhetoric between the new leaders of the North
and South, as well as the United States. The North has had a long history of
saber rattling and provocation in an effort to lift economic sanctions against
the country, and it is believed this time is no different. Nonetheless, these
types of externalities are likely to create pockets of volatility in the
short-term. Lastly, in what was viewed as a surprise to the markets, in April,
the Bank of Japan (BOJ) announced, under new leadership, it would further expand
its monetary base twofold by purchasing Japanese government bonds of any
maturity in addition to stocks and property-linked assets. The goal of the
program, according to the BOJ, is to stimulate growth and raise the inflation
rate to 2% as the country has battled a difficult deflationary cycle for nearly
two decades. The Nikkei Index rallied 12.4% (local) in April on the quantitative
easing announcement.

PERFORMANCE ANALYSIS

FSD gained 8.63% on an NAV basis during this six-month period, outperforming its
benchmark, the Bank of America Merrill Lynch U.S. High Yield Master II
Constrained Index, which gained 7.26%. The top-performing industries in the
high-yield market during the period included insurance, technology, banking,
basic industry and utilities. The industries that did not perform as well
included media, telecommunications, real estate, consumer non-cyclicals and
energy. New issue supply has been very strong with companies continuing to come
to the market for financing needs. The relative stability of the U.S. market and
low yields have provided an attractive backdrop for issuers.

We continue to maintain a portfolio beta slightly above the market, which helped
the Fund during the period. The principal sectors we favor continue to include
financials, gaming, homebuilders, building materials and coal and steel
companies. The top-performing names held in the Fund were autos: Ford and GM; as
well as European financials: ABN Amro, Republic of Portugal and Deutsche Post
Finance. The laggards during the period included Mexican home and infrastructure
builders: Urbi Desarrollos Urbanos, Desarrolladora Homex, and Empresas ICA. In
late 2012, the Mexican government made drastic changes to subsidies within
housing which created a major cash drain for homebuilders; subsidies were
re-directed to multiple dwelling apartment buildings, which require a larger
amount of upfront working capital, instead of new single family homes. This
unanticipated change halted cash flow to these builders who are currently
working to restructure and save their businesses. The bottom performers also
included OGX and Intergen.

With respect to the short positions in the Fund, the Fund sold short U.S.
Treasury bonds in order to reduce the Fund portfolio's exposure to interest rate
risk, while at the same time purchasing additional high-yield securities that
would otherwise be unavailable on an unlevered basis. The Treasury short
detracted from returns as Treasury yields fell modestly across the curve during
the period. This was more than offset, however, as the additional high-yield
long positions generally rallied in the positive high-yield market environment.
It is important to note that leverage can magnify both the portfolio's gains as
well as its losses.

OUTLOOK

Our base case scenario calls for a moderate, slow growth economic environment in
the U.S., which is more than adequate to support a healthy high-yield market. We
continue to reiterate our belief that the high-yield asset class is not trading
in a "bubble" for a number of reasons: 1) current spreads, while having traded
through their long-term average, remain wide to their record levels set in 2007;
2) yields trading at record lows is much more a function of Treasury rates; and
3) credit fundamentals point to a healthy issuer base while declining default
rates suggest continued low credit costs. Moreover, when interest rates do begin
to rise, current spreads in high yield will likely provide a greater cushion
against rising rates than is typically the case, resulting in a longer period of
price stability.

High-yield issuers have benefited materially from the receptive new issue market
of the past several years by extending maturities and strengthening their
liquidity position. In fact, the majority of new issuance has been for this
purpose. Although we have seen a slight easing in credit standards for recent
new issues, this is not atypical at this stage in the credit cycle. We stated in
our previous letter that absolute quality is surprisingly strong, and leverage,
as measured by net debt-to-EBITDA, is well below the historical average. More
importantly, low rates have helped improve interest coverage ratios, which
reflect a company's ability to service their debt payments. In summary, we
expect further spread compression, and we do not expect to reduce the Fund's
portfolio beta significantly until at least later in the year.

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

(b)   The Fund previously held non-transferable trust units that were originally
      issued to facilitate distribution of General Motors common stock and
      warrants pursuant to the General Motors Bankruptcy Plan of Reorganization.
      The non-transferable trust units existed only for the purpose of receiving
      residual cash, if any, from the General Motors Bankruptcy. These units
      were received in exchange for the previously owned General Motors 8.375%
      Corporate Notes that were scheduled to mature on July 15, 2033. On June
      12, 2012, the holders of these units received new transferable General
      Motors Unsecured Claim (GUC) Trust Units, which were created to hold and
      administer the common stock and warrants of General Motors Company to be
      contributed to the GUC Trust under the General Motors Bankruptcy Plan of
      Reorganization.

(c)   Security issued by a U.S. incorporated entity, that has its principal
      value denominated in the listed foreign currency.

(d)   Fixed-to-floating rate security. The interest rate shown reflects the
      fixed rate in effect at April 30, 2013. At a predetermined date, the fixed
      rate will change to a floating rate.

(e)   Perpetual maturity.

(f)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended and may be resold in transactions exempt from
      registration, normally to qualified institutional buyers. Pursuant to
      procedures adopted by the Fund's Board of Trustees, this security has been
      determined to be liquid by MacKay Shields LLC, the Fund's 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, 2013, securities noted as such amounted to
      $219,426,367, or 30.55% of net assets.

(g)   The issuer is in default. Income is not being accrued.

(h)   Floating rate security. The interest rate shown reflects the rate in
      effect at April 30, 2013.

(i)   Ratings below Baa3 by Moody's Investors Service, Inc. or BBB- by Standard
      & Poor's Ratings Group are considered to be below investment grade.

PORTFOLIO OF INVESTMENTS - (CONTINUED)

(j)   Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund
      invests pay interest at rates which are periodically predetermined by
      reference to a base lending rate plus a premium. These base lending rates
      are generally (i) the lending rate offered by one or more major European
      banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the
      prime rate offered by one or more United States banks or (iii) the
      certificate of deposit rate. Certain Senior Loans are subject to a LIBOR
      floor that establishes a minimum LIBOR rate. The interest rate shown
      reflects the rate in effect at April 30, 2013.

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

(m)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of April 30, 2013, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $64,633,745 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $14,575,214.

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           APRIL 30, 2013 (UNAUDITED)


                              1. FUND DESCRIPTION

First Trust High Income Long/Short Fund (the "Fund") is a diversified,
closed-end management investment company organized as a Massachusetts business
trust on June 18, 2010, and is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940, as amended (the
"1940 Act"). The Fund trades under the ticker symbol FSD on the New York Stock
Exchange ("NYSE").

The Fund's primary investment objective is to provide current income. The Fund's
secondary objective is capital appreciation. The Fund seeks to achieve its
investment objectives by investing, under normal market conditions, a majority
of its assets in a diversified portfolio of U.S. and foreign (including emerging
markets) high-yield corporate fixed-income securities of varying maturities that
are rated below-investment grade at the time of purchase. For purposes of this
strategy, "corporate fixed-income securities" include corporate bonds,
debentures, notes, commercial paper and other similar types of corporate debt
instruments, including instruments issued by corporations with direct or
indirect government ownership, as well as asset-backed securities, preferred
shares, senior floating-rate loan participations, commitments and assignments
("Senior Loans")(1), payment-in-kind securities, zero-coupon bonds, bank
certificates of deposit, fixed time deposits, bankers' acceptances and
derivative instruments that provide the same or similar economic impact as a
physical investment in the above securities. Below-investment grade fixed-income
securities are commonly referred to as "high-yield" or "junk" bonds and are
considered speculative with respect to the issuer's capacity to pay interest and
repay principal. As part of its investment strategy, the Fund intends to
maintain both long and short positions in securities under normal market
conditions. The Fund will take long positions in securities that MacKay Shields
LLC ("MacKay" or the "Sub-Advisor") believes offer the potential for attractive
returns and that it considers in the aggregate to have the potential to
outperform the Fund's benchmark, the Bank of America Merrill Lynch U.S. High
Yield Master II Constrained Index (the "Index"). The Fund will take short
positions in securities that the Sub-Advisor believes in the aggregate will
underperform the Index. The Fund's long positions, either directly or through
derivatives, may total up to 130% of the Fund's Managed Assets. The Fund's short
positions, either directly or through derivatives, may total up to 30% of the
Fund's Managed Assets. "Managed Assets" means the average daily gross asset
value of the Fund (which includes the principal amount of any borrowings), minus
the sum of the Fund's liabilities. 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 its financial statements. The
preparation of 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 net asset value ("NAV") of the Common Shares of the Fund is determined
daily, as of the close of regular trading on the 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 NAV per Common Share
is calculated by dividing the value of all assets of the Fund (including accrued
interest and dividends), less all liabilities (including accrued expenses,
dividends declared but unpaid and any borrowings of the Fund), by the total
number of Common Shares outstanding.

The Fund's investments are valued daily in accordance with valuation procedures
adopted by the Fund's Board of Trustees and in accordance with provisions of the
1940 Act. The Fund's securities will be valued as follows:

    Corporate bonds, notes, U.S. government securities, mortgage-backed
    securities, asset-backed securities 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 Fund'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.


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

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           APRIL 30, 2013 (UNAUDITED)


      A ready market does not exist for some of these investments. As such,
      these values may differ from the values that would have been used had a
      ready market for these investments existed, and the differences could be
      material.

      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 price on the exchange on which they are principally
      traded or, for NASDAQ and AIM securities, the official closing price.
      Securities traded on more than one securities exchange are valued at the
      last sale price or official closing price, as applicable, at the close of
      the securities exchange representing the principal market for such
      securities.

      Securities traded in an over-the-counter market are valued at their
      closing bid prices.

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

      Forward foreign currency contracts are 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.

      Debt securities having a remaining maturity of sixty days or less when
      purchased are valued at cost adjusted for amortization of premiums and
      accretion of discounts.

In the event that the pricing service or dealer does not provide a valuation, or
the valuations received are deemed unreliable, the Fund's Board of Trustees has
designated First Trust Advisors L.P. ("First Trust") to use a fair value method
to value the Fund's securities. Additionally, if events occur after the close of
the principal markets for certain securities (e.g., domestic debt and foreign
securities) that could materially affect the Fund's NAV, First Trust may use a
fair value method to value the Fund's securities. The use of fair value pricing
is governed by valuation procedures adopted by the Fund's Board of Trustees, and
in accordance with the provisions of the 1940 Act. As a general principle, the
fair value of a security is the amount which the Fund might reasonably expect to
receive for the security upon its current sale. In light of the judgment
involved in fair valuations, there can be no assurance that a fair value
assigned to a particular security will be the amount which the Fund might be
able to receive upon its current sale. Fair valuation of a security is based on
the consideration of all available information, including, but not limited to,
the following:

      1)    the fundamental business data relating to the issuer;

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

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

      4)    the financial statements of the issuer;

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

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

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

      8)    the coupon payments;

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

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

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

      12)   other relevant factors.


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

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

                                                                         Page 23

                                          APRIL 30, 2013 (UNAUDITED)

      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 methodology 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, 2013, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME:

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

C. UNFUNDED LOAN COMMITMENTS:

The Fund may enter into certain credit agreements, all or a portion of which may
be unfunded. The Fund is obligated to fund these loan commitments at the
borrower's discretion. The Fund did not have unfunded delayed draw loan
commitments as of April 30, 2013.

D. 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 to
exchange one currency for another at a future date and at a specified price. The
Fund uses forward foreign currency contracts to facilitate transactions in
foreign securities and to manage the Fund's foreign currency exposure. These
contracts are valued daily, and the Fund's net equity therein, representing
unrealized gain or loss on the contracts as measured by the difference between
the forward foreign exchange rates at the dates of entry into the contracts and
the forward rates at the reporting date, is included in "Unrealized
appreciation/(depreciation) on forward foreign currency contracts" on the
Statement of Assets and Liabilities. When the forward contract is closed, the
Fund records a realized gain or loss equal to the difference between the
proceeds from (or the cost of) the closing transaction and the Fund's basis in
the contract. This realized gain or loss is included in "Net realized gain
(loss) on forward foreign currency contracts" on the Statement of Operations.
Risks arise from the possible inability of counterparties to meet the terms of
their contracts and from movement in currency and securities values and interest
rates. Due to the risks, the Fund could incur losses in excess of the net
unrealized value shown on the Schedule of Forward Foreign Currency Contracts.

During the six months ended April 30, 2013, the open and close notional values
of forward foreign currency contracts were $1,063,918,647 and $(763,505,591),
respectively.

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 fluctuation in exchange rates between the
initial purchase trade date and subsequent sale trade date is included in "Net
realized gain (loss) on foreign currency transactions" on the Statement of
Operations.

                           APRIL 30, 2013 (UNAUDITED)


F. 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 a short sale is engaged in, the security
sold short must be borrowed and delivered to the counterparty. Short selling
allows the Fund to profit from a decline in a market price to the extent such
decline exceeds the transaction costs and the costs of borrowing the securities.
The Fund will pay a fee or premium to borrow the securities 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. Any such
gain or loss may be offset, completely or in part, by the change in the value of
the long portion of the Fund's portfolio. The Fund is subject to the risk it may
be unable to reacquire a security to terminate a short position except at a
price substantially in excess of the last quoted price. Also, there is the risk
that the counterparty to a short sale may fail to honor its contractual terms,
causing a loss to the Fund.

G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:

Level dividend distributions are declared and paid monthly to Common
Shareholders after the payment of interest and/or dividends in connection with
leverage. The level dividend rate may be modified by the Board of Trustees from
time to time. If, for any monthly distribution, net investment company taxable
income, if any (which term includes net short-term capital gain), is less than
the amount of the distribution, the difference will generally be a tax-free
return of capital distributed from the Fund's assets. Distributions of any net
long-term capital gains earned by the Fund are distributed at least annually.
Distributions will automatically be reinvested into additional Common Shares
pursuant to the Fund's Dividend Reinvestment Plan unless cash distributions are
elected by the shareholder.

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 NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some point in the future. The character of
distributions for tax reporting purposes will depend on the Fund's investment
experience during the remainder of its fiscal year.

The tax character of distributions paid during the fiscal year ended October 31,
2012 was as follows:


Distributions paid from:

Ordinary income.......................................   $ 57,752,609
Capital gain .........................................          9,358
Return of capital ....................................             --

As of October 31, 2012, the distributable earnings and net assets on a tax basis
were as follows:


Undistributed ordinary income ........................   $  3,058,633
Undistributed capital gains ..........................             --
                                                         ------------
Total undistributed earnings .........................      3,058,633
Accumulated capital and other losses .................    (17,746,452)
Net unrealized appreciation (depreciation) ...........     13,675,154
                                                         ------------
Total accumulated earnings (losses) ..................     (1,012,665)
Other ................................................             --
Paid-in capital ......................................    687,727,395
                                                         ------------
Net assets ...........................................   $686,714,730
                                                         ============

H. 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 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.

Under the Regulated Investment Company Modernization Act of 2010 (the "Act"),
net capital losses arising in taxable years after December 22, 2010, may be
carried forward indefinitely, and their character is retained as short-term
and/or long-term losses. Previously, net capital losses were carried forward
eight years and treated as short-term losses. As a transition rule, the Act
requires that post-enactment

                                                                         Page 25

                           APRIL 30, 2013 (UNAUDITED)


net capital losses be used before pre-enactment net capital losses. At October
31, 2012, the Fund had no pre-enactment net capital losses for federal income
tax purposes. At October 31, 2012, the Fund had post-enactment net capital
losses for federal income tax purposes of $17,746,452 to be carried forward
indefinitely.

The Fund is subject to certain limitations under the 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.

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2010, 2011
and 2012 remain open to federal and state audit. As of April 30, 2013,
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.

I. EXPENSES:

The Fund will pay all expenses directly related to its operations.

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

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for the ongoing monitoring of the Fund's investment
portfolio, managing the Fund's business affairs and providing certain
administrative services necessary for the management of the Fund. For these
investment management services, First Trust is entitled to a monthly fee
calculated at an annual rate of 1.00% of the Fund's Managed Assets. First Trust
also provides fund reporting services to the Fund for a flat annual fee in the
amount of $9,250.

MacKay serves as the Fund's sub-advisor and manages the Fund's portfolio subject
to First Trust's supervision. The Sub-Advisor receives a portfolio management
fee at an annual rate of 0.50% of Managed Assets that is paid by First Trust
from its investment advisory fee.

BNY Mellon Investment Servicing (US) Inc. ("BNYM IS") serves as the Fund's
administrator, fund accountant and transfer agent in accordance with certain fee
arrangements. As administrator and fund accountant, BNYM IS is responsible for
providing certain administrative and accounting services to the Fund, including
maintaining the Fund's books of account, records of the Fund's securities
transactions, and certain other books and records. As transfer agent, BNYM IS is
responsible for maintaining shareholder records for the Fund. The Bank of New
York Mellon ("BNYM") serves as the Fund's custodian in accordance with certain
fee arrangements. As custodian, BNYM is responsible for custody of the Fund's
assets.

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 of $125,000 per year and an annual per fund fee of $4,000 for each
closed-end fund or other actively managed fund and $1,000 for each index fund in
the First Trust Fund Complex. The fixed annual retainer is allocated pro rata
among each fund in the First Trust Fund Complex based on net assets.

Chairman of the Audit Committee is paid $10,000 annually, and each of the
Chairmen of the Nominating and Governance Committee and the Valuation Committee
is paid $5,000 annually 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 each Committee
chairman will serve two-year terms until December 31, 2013, before rotating to
serve as chairman of another committee or as Lead Independent Trustee. After
December 31, 2013, the Lead Independent Trustee and Committee Chairmen will
rotate every three years. The officers and "Interested" Trustee receive no
compensation from the funds for acting in such capacities.

                      4. PURCHASES AND SALES OF SECURITIES

Cost of purchases and proceeds from sales of investments, excluding short-term
investments, for the six months ended April 30, 2013, were $127,041,167 and
$144,524,060, respectively.

                               5. INDEMNIFICATION

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

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           APRIL 30, 2013 (UNAUDITED)


                             6. RISK CONSIDERATIONS

Risks are inherent in all investing. The following summarizes some, but not all,
of the risks that should be considered for the Fund. For additional information
about the risks associated with investing in the Fund, please see the Fund's
prospectus and statement of additional information, as well as other Fund
regulatory filings.

INVESTMENT AND MARKET RISK: An investment in the Fund's Common Shares is subject
to investment risk, including the possible loss of the entire principal
invested. An investment in Common Shares represents an indirect investment in
the securities owned by the Fund. The value of these securities, like other
market investments, may move up or down, sometimes rapidly and unpredictably.
Common Shares at any point in time may be worth less than the original
investment, even after taking into account the reinvestment of Fund dividends
and distributions. Security prices can fluctuate for several reasons including
the general condition of the securities markets, or when political or economic
events affecting the issuers occur. When the Advisor or Sub-Advisor determines
that it is temporarily unable to follow the Fund's investment strategy or that
it is impractical to do so (such as when a market disruption event has occurred
and trading in the securities is extremely limited or absent), the Fund may take
temporary defensive positions.

BELOW-INVESTMENT GRADE SECURITIES RISK: The Fund invests in below-investment
grade securities. The market values for high-yield securities tend to be very
volatile, and these securities are less liquid than investment grade debt
securities. For these reasons, an investment in the Fund is subject to the
following specific risks: (a) increased price sensitivity to changing interest
rates and to a deteriorating economic environment; (b) greater risk of loss due
to default or declining credit quality; (c) adverse issuer specific events are
more likely to render the issuer unable to make interest and/or principal
payments; and (d) a negative perception of the high-yield market may depress the
price and liquidity of high-yield securities.

DISTRESSED SECURITIES RISK: The Fund may invest in securities issued by
companies in a bankruptcy reorganization proceeding, subject to some other form
of a public or private debt restructuring or otherwise in default or in
significant risk of default in the payment of interest or repayment of principal
or trading at prices substantially below other below-investment grade debt
securities of companies in similar industries. Distressed securities frequently
do not produce income while they are outstanding. The Fund may be required to
incur certain extraordinary expenses in order to protect and recover its
investment. Therefore, to the extent the Sub-Advisor seeks capital appreciation
through investment in distressed securities, the ability to achieve current
income may be diminished.

ECONOMIC CONDITIONS RISK: Adverse changes in economic conditions are more likely
to lead to a weakened capacity of a high-yield issuer to make principal payments
and interest payments than an investment grade issuer. An economic downturn
could severely affect the ability of highly leveraged issuers to service their
debt obligations or to repay their obligations upon maturity. Under adverse
market or economic conditions, the secondary market for high-yield securities
could contract further, independent of any specific adverse changes in the
condition of a particular issuer and these securities may become illiquid. As a
result, the Sub-Advisor could find it more difficult to sell these securities or
may be able to sell the securities only at prices lower than if such securities
were widely traded.

FIXED-INCOME SECURITIES RISK: Debt securities, including high-yield securities,
are subject to certain risks, including: (i) issuer risk, which is the risk that
the value of fixed-income securities may decline for a number of reasons which
directly relate to the issuer, such as management performance, financial
leverage and reduced demand for the issuer's goods and services or, in the case
of asset-backed issuers, a decline in the value and/or cash flows of the
underlying assets; (ii) reinvestment risk, which is the risk that income from
the Fund's portfolio will decline if the proceeds from matured, traded or called
bonds are reinvested at market interest rates that are below the portfolio's
current earnings rate; (iii) prepayment risk, which is the risk that during
periods of declining interest rates, the issuer of a security may exercise its
option to prepay principal earlier than scheduled, forcing the reinvestment in
lower yielding securities; and

(iv) credit risk, which is the risk that a security in the Fund's portfolio will
decline in price or the issuer fails to make interest payments when due because
the issuer of the security experiences a decline in its financial status.

INTEREST RATE RISK: The Fund's portfolio is also subject to interest rate risk.
Interest rate risk is the risk that fixed-income securities will decline in
value because of changes in market interest rates. Investments in debt
securities with long-term maturities may experience significant price declines
if long-term interest rates increase.

SHORT SELLING RISK: Short selling allows the Fund to profit from a decline in
market price to the extent such decline exceeds the transaction costs and the
costs of borrowing the securities. If a security sold short increases in price,
the Fund may have to cover its short position at a higher price than the short
sale price, resulting in a loss. The Fund may have substantial short positions
and must borrow those securities to make delivery to the buyer. The Fund may not
be able to borrow a security that it needs to deliver or it may not be able to
close out a short position at an acceptable price and may have to sell related
long positions before it had intended to do so. Thus, the Fund may not be able
to successfully implement its short sale strategy due to limited availability of
desired securities or for other reasons. Also, there is the risk that the
counterparty to a short sale may fail to honor its contractual terms, causing a
loss to the Fund. Because losses on short sales arise from increases in the
value of the security sold short, such losses are theoretically unlimited. The
use of short sales in combination with long

                                                                         Page 27

positions in the Fund's portfolio in an attempt to improve performance or reduce
overall portfolio risk may not be successful and may result in greater losses or
lower positive returns than if the Fund held only long positions. It is possible
that the Fund's long securities positions will decline in value at the same time
that the value of its short securities positions increase, thereby increasing
potential losses to the Fund.

By investing the proceeds received from selling securities short, the Fund could
be deemed to be employing a form of leverage, which creates special risks. The
use of leverage may increase the Fund's exposure to long securities positions
and make any change in the Fund's NAV greater than it would be without the use
of leverage. This could result in increased volatility of returns. There is no
guarantee that any leveraging strategy the Fund employs will be successful
during any period in which it is employed.

CURRENCY RISK: The value of securities denominated or quoted in foreign
currencies may be adversely affected by fluctuations in the relative currency
exchange rates and by exchange control regulations. The Fund's investment
performance may be negatively affected by a devaluation of a currency in which
the Fund's investments are denominated or quoted. Further, the Fund's investment
performance may be significantly affected, either positively or negatively, by
currency exchange rates because the U.S. dollar value of securities denominated
or quoted in another currency will increase or decrease in response to changes
in the value of such currency in relation to the U.S. dollar. While certain of
the Fund's non-U.S. dollar-denominated securities may be hedged into U.S.
dollars, hedging may not alleviate all currency risks.

                              7. 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 that there were the following subsequent events:

On May 20, 2013, the Fund declared a dividend of $0.1155 per share to Common
Shareholders of record on June 5, 2013, payable June 17, 2013.

On June 20, 2013, the Fund declared a dividend of $0.1155 per share to Common
Shareholders of record on July 3, 2013, payable July 15, 2013.

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           APRIL 30, 2013 (UNAUDITED)


                           DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your
Common Shares with a brokerage firm that participates in the Fund's Dividend
Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund,
to receive cash distributions, all dividends, including any capital gain
distributions, on your Common Shares will be automatically reinvested by BNY
Mellon Investment Servicing (US) Inc. (the "Plan Agent"), in additional Common
Shares under the Plan. If you elect to receive cash distributions, you will
receive all distributions in cash paid by check mailed directly to you by the
Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will
receive will be determined as follows:

      (1)   If Common Shares are trading at or above net asset value ("NAV") at
            the time of valuation, the Fund will issue new shares at a price
            equal to the greater of (i) NAV per Common Share on that date or
            (ii) 95% of the market price on that date.

      (2)   If Common Shares are trading below NAV at the time of valuation, the
            Plan Agent will receive the dividend or distribution in cash and
            will purchase Common Shares in the open market, on the NYSE or
            elsewhere, for the participants' accounts. It is possible that the
            market price for the Common Shares may increase before the Plan
            Agent has completed its purchases. Therefore, the average purchase
            price per share paid by the Plan Agent may exceed the market price
            at the time of valuation, resulting in the purchase of fewer shares
            than if the dividend or distribution had been paid in Common Shares
            issued by the Fund. The Plan Agent will use all dividends and
            distributions received in cash to purchase Common Shares in the open
            market within 30 days of the valuation date except where temporary
            curtailment or suspension of purchases is necessary to comply with
            federal securities laws. Interest will not be paid on any uninvested
            cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving
written notice to the Plan Agent, or by telephone at (866) 340-1104, in
accordance with such reasonable requirements as the Plan Agent and the Fund may
agree upon. If you withdraw or the Plan is terminated, you will receive a
certificate for each whole share in your account under the Plan, and you will
receive a cash payment for any fraction of a share in your account. If you wish,
the Plan Agent will sell your shares and send you the proceeds, minus brokerage
commissions.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives
written confirmation of all transactions in the accounts, including information
you may need for tax records. Common Shares in your account will be held by the
Plan Agent in non-certificated form. The Plan Agent will forward to each
participant any proxy solicitation material and will vote any shares so held
only in accordance with proxies returned to the Fund. Any proxy you receive will
include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions
in Common Shares. However, all participants will pay a pro rata share of
brokerage commissions incurred by the Plan Agent when it makes open market
purchases.

Automatically reinvesting dividends and distributions does not mean that you do
not have to pay income taxes due upon receiving dividends and distributions.
Capital gains and income are realized although cash is not received by you.
Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate
in the Plan, you will not be able to participate in the Plan and any dividend
reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of
the Board of Trustees the change is warranted. There is no direct service charge
to participants in the Plan; however, the Fund reserves the right to amend the
Plan to include a service charge payable by the participants. Additional
information about the Plan may be obtained by writing BNY Mellon Investment
Servicing (US) Inc., 301 Bellevue Parkway, Wilmington, Delaware 19809.
