                  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
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 common share price will fluctuate and Fund shares,
when sold, may be worth more or less than their original cost.

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

                            HOW TO READ THIS REPORT

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

By reading the portfolio commentary by the portfolio management team of the
Fund, you may obtain an understanding of how the market environment affected the

MacKay are just that: informed opinions. They should not be considered to be

the date on the cover of this report. The material risks of investing in the

SHAREHOLDER LETTER

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2017


Dear Shareholders:

Thank you for your investment in First Trust High Income Long/Short Fund.

First Trust is pleased to provide you with the annual report which contains
detailed information about your investment for the 12 months ended October 31,
2017, including a market overview and a performance analysis for the period. We
encourage you to read this report carefully and discuss it with your financial
advisor.

The U.S. bull market continued through the November 2016 election and the first
nine months of the Trump presidency. During that period, November 8, 2016
(Election Day 2016) through October 31, 2017, the S&P 500(R) Index (the "Index")
posted a total return of 22.73%, according to Bloomberg. Ten of the eleven Index
sectors were up on a total return basis as well. Since the beginning of 2017
through October 31, 2017, the Index has closed its trading sessions at all-time
highs on 50 occasions. Finally, as of October 31, 2017, the Index has spent the
entire year in positive territory. This has only happened in 10 different years
over the past seven decades.

The current bull market, as measured from March 9, 2009 through October 31, 2017
is the second longest in history. While we are optimistic about the U.S.
economy, we are aware that no one can know how markets will perform in different
economic environments. We are also upbeat about the potential for world economic
growth turning higher. While no one can predict the future, the International
Monetary Fund sees world real gross domestic product rising by an estimated 0.5
percentage points from the 3.2% posted in 2016 to the 3.7% it is projecting for
2018.

We believe that one should invest for the long term and be prepared for market
volatility by keeping current on your portfolio and investing goals by speaking
regularly with your investment professional. It is also important to keep in
mind that past performance can never guarantee future results.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on bringing
the types of investments that we believe can help you reach your financial
goals.

Sincerely,

/s/ James A. Bowen

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

MARKET RECAP

This report covers the Fund for the 12-month period ending October 31, 2017.

For the 12-month period ended October 31, 2017, risk-based assets rallied
following the strong performance which began in early 2016. The prolonged rally
in credit-sensitive fixed income markets has been driven by a generally sound
economic backdrop and optimistic investor outlook. Factors that contributed to
the market's robust performance were optimism following the U.S. presidential
election, a rebound in oil prices, buoyant job growth in the U.S., and a
positive global economic backdrop, including the Organization for Economic
Cooperation and Development's ("OECD") announcement that all 45 countries it
tracks have shown economic growth in 2017. This is the first instance of
simultaneous global growth since 2007. Concurrently, the International Monetary
Fund ("IMF") increased its global growth forecast to 3.5% for 2017, up from 3.2%
in 2016. Japan, Brazil, Spain, and Italy were among the countries to post
improved economic numbers recently, providing some reassurance for investors
worried about the future trajectory of Chinese and U.S. growth. As widely
anticipated, the Federal Reserve (the "Fed") also raised the Fed funds target
rate to 1.25% at their June meeting. Expectations remain high that the Federal
Open Market Committee ("FOMC") will embark on tapering before year end and that
the European Central Bank ("ECB") will begin to outline its plans for reducing
its own quantitative easing ("QE"). Hurricanes, tensions with North Korea, and
presidential tweets were not as friendly for risky assets during the last few
months, and we observed a brief period of softness in the markets during the
summer. For the fiscal year ended October 31, 2017, equities soared, delivering
high double-digit returns. The Russell 2000(R) Index, which tracks small-cap
U.S. equities, was the best performer during the period, delivering a return of
27.9%. The MSCI EAFE Index, which tracks international equities, followed with a
return of 24.0%, while the S&P 500(R) Index, which tracks large-cap U.S.
equities, increased by 23.6%. Outside of equities, U.S. high-yield securities
delivered respectable results, gaining 9.1% according to the ICE BofAML US High
Yield Constrained Index. U.S. Corporates were next in line, returning 3.5% for
this period, according to the Bloomberg Barclays US Corporate Index. U.S.
Treasuries, as measured by the ICE BofAML 10 Year US Treasury Index, declined by
3.0%.

At the start of the period (November, 2016), U.S. capital markets were highly
focused on the U.S. Presidential election and responded favorably to the Trump
victory. This marked a watershed moment as the Republican Party gained control
of both the executive and legislative branches of government. Sentiment-based
economic indicators continue to remain high in the U.S., although progress on
the Trump administration's economic, tax, trade, and infrastructure policies has
diminished given the confrontational political atmosphere in Washington, D.C.
Nevertheless, the U.S. economy continues to expand modestly although auto sales
are weakening. The outcome of the Dodd Frank bank exams was released in late
June, and all 34 of the largest banks in the U.S. cleared the Fed's stress test.
Fed Board of Governor Jerome Powell noted, "this year's results show that, even
during a severe recession, our large banks would remain well capitalized."

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                                 ANNUAL REPORT
                          OCTOBER 31, 2017 (UNAUDITED)

During the period, the Fed officially laid out plans to reduce its $4.5 trillion
balance sheet, announcing in September, an October start date for the plan. The
FOMC stated that it "intends to gradually reduce holdings by decreasing the
reinvestment of principal payments it receives". U.S. Treasuries and agency debt
and mortgage-backed securities holdings will be affected based on a formula and
schedule detailed in the Fed's press release. The FOMC added that it would cease
the incremental tapering if "a material deterioration of the economic outlook
was to warrant a sizeable reduction in the Committee's target for the federal
funds rate." Although the FOMC left short-term rates unchanged after its October
meeting, we believe the markets continue to attach a high probability of a final
2017 rate increase at the December meeting. On November 2, 2017, President Trump
announced Jerome Powell as his nominee to replace Janet Yellen as Fed Chair. If
confirmed by the Senate, Powell will be the first Fed Chairperson in four
decades to not have a Ph.D. in economics. Mr. Powell is an attorney and past Fed
governor with extensive regulatory experience and is considered a policy
centrist by many.

Other central banks were in the news as well. Although the ECB announced that it
will trim its corporate bond buying program from (euro)60 billion to (euro)30
billion per month commencing in January of 2018, the central bank indicated that
it intends to keep its main rate at zero for "an extended period of time, and
well past the horizon of net asset purchases."

Global growth continues to improve. The IMF revised its global growth forecasts,
and U.S. gross domestic product ("GDP") for the third quarter of 2017 came in at
3.0%, following 3.1% for the second quarter. These data follow a late September
rise in European business and consumer sentiment as tracked by the European
Commission. Second quarter investment in the Eurozone continued to advance at
3.5% for the entire region, with Germany up 6.2% and Italy up 3.6% according to
data released in early October, 2017.

PERFORMANCE ANALYSIS

Overall, U.S. high-yield (HY) securities have performed quite well for the
12-month period ended October 31, 2017. According to JP Morgan, par-weighted HY
defaults over the last 12 months ("LTM") have dropped, and the drop is largely
due to the rolling off of early 2016 energy company defaults. JP Morgan pegged
the HY default rate - including distressed exchanges - down to 1.34% as of
October 2017. LTM recoveries of 49.0% topped the 25-year historical average of
41.2% and have been improving throughout 2017. All sectors within the widely
watched ICE BofAML US High Yield Constrained Index(1) delivered positive
returns; the Transportation (17.0%), Financial Services (11.8%), and Services
(10.8%) sectors were the strongest performers.

The Fund outperformed its benchmark, the ICE BofAML US High Yield Constrained
Index, on a total gross return(2), share price and net asset value ("NAV") basis
for the 12-month period ended October 31, 2017. The Fund returned 18.52%2 and
11.98% on a share price and NAV basis, respectively, compared with the
benchmark, which gained 9.14% for the period. The Fund's exposure to insurance
hybrid preferred bonds as well as issue selection within the basic industries,
specifically the building & construction and steel producers subsectors, were
beneficial to performance, whereas the Fund's underweight positioning within the
energy sector detracted from relative results.

The Fund maintained short positions in U.S. Treasury bonds during the period,
which were used to reduce the portfolio's exposure to interest rate risk, while
at the same time purchasing additional high-yield securities to increase the
size of the portfolio. The Fund benefited from its additional long exposure to
high-yield bonds, offset slightly by the borrowing costs involved, as the
high-yield market rallied in the period. Given that the U.S. Treasury curve
exhibited a bear flattener during the period, the short U.S. Treasury position
added to results.


(1)   The ICE BofAML US High Yield Constrained Index tracks the performance of
      U.S. dollar denominated below investment grade corporate debt publicly
      issued in the U.S. domestic market but caps issuer exposure at 2%. Indexes
      are unmanaged and an investor cannot invest directly in an index.

(2)   Total return is based on a combination of reinvested divindends, capital
      gain and return of capital distributions, if any, at prices obtained by
      the Dividend Reinvestment Plan and changes in NAV per share for net asset
      value returns and changes in Common Share price for market value returns.
      Total returns do not affect sales load and are not annualized for periods
      less than one year. Past performance is not indicative of future results.

                          OCTOBER 31, 2017 (UNAUDITED)

OUTLOOK

While we believe the markets continue to embrace the 'reflation trade' supported
by an expectation of favorable corporate tax reform, we do expect U.S. economic
growth to slow over the coming months. Lower corporate tax rates could further
extend the current earnings cycle, but headwinds remain as the Fed continues to
tighten monetary conditions. We have observed that U.S. economic growth slows
substantially 24 to 36 months into a tightening cycle. While we do realize that
the pace of tightening has been unusually slow and therefore the lag could be
greater, we also recognize that the Fed has had to use every tool at its
disposal just to achieve moderate credit growth, which is the fuel of all
expansions. Given this relatively slow credit growth, it is not too hard to
imagine that credit might be more sensitive to tightening monetary policy than
has been the case in the past, in our opinion.

From a technical perspective, we believe there are also many signs that we are
in the later stages of an expansion as both high-yield and investment-grade
credit premiums have narrowed dramatically over the past year and the S&P 500(R)
Index's trailing price-to-earnings ratio is near a record. In our opinion,
market participants are indiscriminately chasing returns which is typical of the
final stages of a rally. While spreads could continue to tighten further,
incremental risk is being rewarded less and less.

FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
PORTFOLIO OF INVESTMENTS (CONTINUED)
OCTOBER 31, 2017

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

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

(b)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, 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 (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 October 31, 2017, securities noted as such amounted to
      $298,970,230 of total investments or 54.8% of net assets.

(c)   Floating or variable rate security.

(d)   Perpetual maturity.

(e)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at October 31, 2017. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(f)   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.

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

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

(i)   Aggregate cost federal income tax purposes is $533,650,834. As of October
      31, 2017, the aggregate gross unrealized appreciation for all investments
      in which there was an excess of value over tax cost was $44,400,729 and
      the aggregate gross unrealized depreciation for all investments in which
      there was an excess of tax cost over value was $8,951,380. The net
      unrealized appreciation was $35,449,349. The amounts presented are
      inclusive of investments sold short and derivative contracts.

*     On June 14, 2017, the Fund commenced a tender offer for up to 15% of its
      outstanding common shares for cash at a price per share equal to 98% of
      the net asset value per share determined on the expiration date. The
      Fund's tender offer expired at 5:00 p.m. New York City time on Thursday,
      July 13, 2017. Since the Fund's tender offer was oversubscribed, the Fund
      purchased 5,284,792 (15%) of its outstanding common shares on a pro-rata
      basis based on the number of shares properly tendered.

**    On September 15, 2015, the Fund commenced a share repurchase program. The
      program originally expired on March 15, 2016, but the Board of Trustees of
      the Fund has subsequently authorized the continuation of the Fund's share
      repurchase program until March 15, 2018. For the years ended October 31,
      2017 and 2016, the Fund repurchased 13,654 and 656,620, respectively, of
      its shares at a weighted-average discount of 13.69% and 15.14%,
      respectively, from net asset value per share. The Fund expects to continue
      to repurchase its outstanding shares until the earlier of (i) the
      repurchase of an additional 978,598 common shares (for an aggregate of
      1,802,808), or (ii) March 15, 2018.

NOTES TO FINANCIAL STATEMENTS

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                                OCTOBER 31, 2017


                                1. ORGANIZATION

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 ICE BofAML US High Yield Constrained Index,
formerly BofA Merrill Lynch US High Yield 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 Fund is considered an investment company and follows accounting and
reporting guidance under Financial Accounting Standards Board ("FASB")
Accounting Standards Codification ("ASC") Topic 946, "Financial
Services-Investment Companies." 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 Fund's 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 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 Fund'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:

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                                OCTOBER 31, 2017


      Corporate bonds, notes, capital preferred securities, 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 a third-party 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.

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

      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.

      Credit default swaps are fair valued using a third-party pricing service
      or, if the third-party pricing service does not provide a value, by quotes
      provided by the selling dealer or financial institution.

      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 fair
      valued using information provided by a third-party pricing service. The
      third-party pricing service primarily uses over-the-counter pricing from
      dealer runs and broker quotes from indicative sheets to value the Senior
      Loans.

      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 a third-party pricing service.

      Fixed income and other debt securities having a remaining maturity of
      sixty days or less when purchased are fair valued at cost adjusted for
      amortization of premiums and accretion of discounts (amortized cost),
      provided the Advisor's Pricing Committee has determined that the use of
      amortized cost is an appropriate reflection of fair value given market and
      issuer-specific conditions existing at the time of the determination.
      Factors that may be considered in determining the appropriateness of the
      use of amortized cost include, but are not limited to, the following:

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

Certain securities may not be able to be priced by pre-established pricing
methods. Such securities may be valued by the Fund's Board of Trustees or its
delegate, the Advisor's Pricing Committee, at fair value. These securities
generally include, but are not limited to, restricted securities (securities
which may not be publicly sold without registration under the Securities Act of
1933, as amended) for which a third-party pricing service is unable to provide a
market price; securities whose trading has been formally suspended; a security
whose market or fair value price is not available from a pre-established pricing
source; a security with respect to which an event has occurred that is likely to
materially affect the value of the security after the market has closed but
before the calculation of the Fund's NAV or make it difficult or impossible to
obtain a reliable market quotation; and a security whose price, as provided by

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                                OCTOBER 31, 2017


the third-party pricing service, does not reflect the security's fair value. As
a general principle, the current fair value of a security would appear to be the
amount which the owner might reasonably expect to receive for the security upon
its current sale. When fair value prices are used, generally they will differ
from market quotations or official closing prices on the applicable exchanges. A
variety of factors may be considered in determining the fair value of such
securities, including, but not limited to, the following:

      1)    the fundamental business data relating to the borrower/issuer;
      2)    an evaluation of the forces which influence the market in which
            these securities are purchased and sold;
      3)    the type, size and cost of a security;
      4)    the financial statements of the borrower/issuer;
      5)    the credit quality and cash flow of the borrower/issuer, based on
            the 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 borrower/issuer, including any ability
            to obtain money or resources from a parent or affiliate and an
            assessment of the borrower's/issuer's management;
     11)    the prospects for the borrower's/issuer's industry, and multiples
            (of earnings and/or cash flows) being paid for similar businesses in
            that industry;
     12)    the borrower's/issuer's competitive position within the industry;
     13)    the borrower's/issuer's ability to access additional liquidity
            through public and/or private markets; and
     14)    other relevant factors.

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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodologies used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of October 31, 2017, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

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

Securities purchased on a when-issued, delayed-delivery or forward purchase
commitment basis may have extended settlement periods. The value of the security
so purchased is subject to market fluctuations during this period. The Fund
maintains liquid assets with a current value at least equal to the amount of its
when-issued, delayed-delivery or forward purchase commitments until payment is
made. At October 31, 2017, the Fund had no when-issued, delayed-delivery or
forward purchase commitments.


                                                                         Page 25

                                OCTOBER 31, 2017


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 any unfunded delayed draw loan
commitments as of October 31, 2017.

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

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 and are shown in "Net realized
gain (loss) on foreign currency transactions" on the Statement of Operations.
The portion of foreign currency gains and losses related to fluctuation 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. 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 by the Fund, but are
not currently owned in the Fund's portfolio. When the Fund engages in a short
sale, the Fund must borrow the security sold short and deliver the security to
the counterparty. Short selling allows the Fund to profit from a decline in a
market price to the extent such decline exceeds the transaction costs and the
costs of borrowing the securities. The Fund 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 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 or borrowing securities on margin. At October 31, 2017,
the Fund had $28,245,711 in borrowings, which approximates fair value,
associated with investments sold short as shown in "Borrowings" on the Statement
of Assets and Liabilities. The borrowings are categorized as Level 2 within the
fair value hierarchy. At October 31, 2017, the Fund had $107,449,583 of
investments sold short as shown in "Investments sold short, at value" on the
Statement of Assets and Liabilities. Interest is charged on these balances at a
rate equal to the Overnight Bank Funding Rate plus 75 basis points and is

charged on payable credit margin balances at a rate equal to the Overnight Bank
Funding Rate less 40 basis points. At October 31, 2017, the Fund had a debit
margin balance with an interest rate of 1.91%. For the year ended October 31,
2017, margin interest expense was $2,456,071, as shown on the Statement of
Operations. For the year ended October 31, 2017, the average margin balance and
interest rate were $152,617,842 and 1.63%, respectively.

G. CREDIT DEFAULT SWAPS

The Fund may enter into credit default swap contracts ("CDS") for investment
purposes or to manage credit risk. A CDS is an agreement between two parties
("Counterparties") to exchange the credit risk of an issuer. Swap agreements may
be privately negotiated in the over-the-counter market as a bilateral contract
or centrally cleared.

A buyer of a CDS is said to buy protection by paying a fixed payment over the
life of the agreement and in some situations an upfront payment to the seller of
the CDS. If a defined credit event occurs (such as payment default or
bankruptcy), the Fund as a protection buyer would cease paying its fixed
payment, the Fund would deliver eligible bonds issued by the reference entity to
the seller, and the seller would pay the full notional value, or the "par
value," of the referenced obligation to the Fund. A seller of a CDS is said to
sell protection and thus would receive a fixed payment over the life of the
agreement and an upfront payment, if applicable. If a credit event occurs, the
Fund as a protection seller would cease to receive the fixed payment stream, the
Fund would pay the buyer "par value" or the full notional value of the
referenced obligation, and the Fund would receive the eligible bonds issued by
the reference entity. In turn, these bonds may be sold in order to realize a
recovery value. Alternatively, the seller of the CDS and its Counterparty may
agree to net the notional amount and the market value of the bonds and make a
cash payment equal to the difference to the buyer of protection. If no credit
event occurs, the Fund receives the fixed payment over the life of the
agreement. As the seller, the Fund would effectively add leverage to its
portfolio because, in addition to its total net assets, the Fund would be
subject to investment exposure on the notional amount of the CDS. In connection
with these agreements, cash and securities may be identified as collateral in
accordance with the terms of the respective swap agreements to provide assets of
value and recourse in the event of default under the swap agreement or
bankruptcy/insolvency of a party to the swap agreement. In the event of a
default by the Counterparty, the Fund will seek withdrawal of this collateral
and may incur certain costs exercising its right with respect to the collateral.
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.

Upon entering into a centrally cleared swap, the Fund is required to deposit
initial margin with the broker in the form of cash or securities in an amount
that varies depending on the size and risk profile of the particular swap. Cash
deposited is segregated and included in "restricted cash" on the Statement of
Assets and Liabilities. The daily change in valuation of centrally cleared swaps
is included in "variation margin on swaps payable" in the Statement of Assets
and Liabilities. Payments received from (paid to) the Counterparty, including at
termination, are recorded as "net realized gain (loss) on swap contracts" on the
Statement of Operations.

Credit default swap contracts are marked to market daily based upon quotations
from brokers, market makers or a third-party pricing service and the change in
value, if any, is recorded as unrealized appreciation (depreciation). For a
credit default swap contract sold by the Fund, payment of the agreed upon amount
made by the Fund in the event of default of the referenced debt obligation is
recorded as the cost of the reference debt obligation purchased/received. The
fund did not hold any swap contracts as of October 31, 2017.

H. 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
U.S. 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. Permanent differences
incurred during the fiscal year ended October 31, 2017, resulting in book and
tax accounting differences, have been reclassified at year end to reflect a
decrease in accumulated net investment income (loss) by $1,479,651, an increase
in accumulated net realized gain (loss) on investments by $1,703,651 and a
decrease to paid-in capital of $224,000. Net assets were not affected by this
reclassification.


                                                                         Page 27

I. INCOME AND OTHER 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.

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 for
up to eight years and treated as short-term losses. As a transition rule, the
Act requires that post-enactment net capital losses be used before pre-enactment
net capital losses. At October 31, 2017, the Fund had no pre-enactment net
capital losses for federal income tax purposes. At October 31, 2017, the Fund
had post-enactment net capital losses for federal income tax purposes of
$57,233,467 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.

Certain losses realized during the current fiscal year may be deferred and
treated as occurring the first day of the following fiscal year for federal
income tax purposes. For the fiscal year ended October 31, 2017, the Fund did
not incur any net ordinary losses.

The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. Taxable years ending 2014, 2015,
2016 and 2017 remain open to federal and state audit. As of October 31, 2017,
management has evaluated the application of these standards to the Fund and has
determined that no provision for income tax is required in the Fund's financial
statements for uncertain tax positions.

J. EXPENSES

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

K. NEW AND AMENDED FINANCIAL REPORTING RULES AND FORMS

On October 13, 2016, the SEC adopted new rules and forms, and amended existing
rules and forms. The new and amended rules and forms are intended to modernize
the reporting of information provided by funds and to improve the quality and
type of information that funds provide to the SEC and investors. In part, the
new and amended rules and forms amend Regulation S-X and require standardized,
enhanced disclosures about derivatives in a fund's financial statements, as well
as other amendments. The compliance date for the amendments of Regulation S-X
was August 1, 2017, which resulted in additional disclosure for variable
interest rate securities and derivative instruments within the Portfolio of
Investments. The new form types and other rule amendments will be effective for
the First Trust funds, including the Fund, for reporting periods beginning on
and after June 1, 2018. Management is evaluating the new form types and other
rule amendments that are effective on and after June 1, 2018 to determine the
impact to the Fund.

                                OCTOBER 31, 2017


L. NEW ACCOUNTING PRONOUNCEMENT

In December 2016, FASB released Accounting Standards Update ("ASU") 2016-19 that
makes technical changes to various sections of the ASC, including Topic 820,
Fair Value Measurement. The changes to Topic 820 are intended to clarify the
difference between a valuation approach and a valuation technique. The changes
to ASC 820-10-50-2 require a reporting entity to disclose, for Level 2 and Level
3 fair value measurements, a change in either or both a valuation approach and a
valuation technique and the reason(s) for the change. The changes to Topic 820
are effective for fiscal years, and interim periods within those fiscal years,
beginning after December 15, 2016. At this time, management is evaluating the
implications of the ASU and has not yet determined its impact on the financial
statements and disclosures.

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
transfer agent in accordance with certain fee arrangements. 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 administrator, fund
accountant and custodian in accordance with certain fee arrangements. As
administrator and fund accountant, BNYM 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 custodian, BNYM is responsible for custody
of the Fund's assets. BNYM IS and BNYM are subsidiaries of The Bank of New York
Mellon Corporation, a financial holding company.

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

Additionally, The Lead Independent Trustee and the Chairmen of the Audit
Committee, Nominating and Governance Committee and Valuation Committee are paid
annual fees to serve in such capacities, with such compensation allocated pro
rata among each fund in the First Trust Fund Complex based on net assets.
Independent Trustees are reimbursed for travel and out-of-pocket expenses in
connection with all meetings. The Lead Independent Trustee and Committee
Chairmen rotate every three years. The officers and "Interested" Trustee receive

currency contracts opened and closed were $110,930,810 and $120,485,533,
respectively.

The average volume of credit default swap contracts was $2,224,658 for the year
ended October 31, 2017.

The Fund does not have the right to offset financial assets and financial
liabilities related to forward foreign currency contracts and swap contracts on
the Statement of Assets and Liabilities.

                               6. 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.

                                7. TENDER OFFER

As previously announced, the Fund conducted a tender offer for up to 15% of its
outstanding common shares for cash at a price per share equal to 98% of the net
asset value per share determined on the expiration date. The Fund's tender offer
expired at 5:00 p.m. New York City time on Thursday, July 13, 2017.

Since the Fund's tender offer was oversubscribed, the Fund purchased 15% of its
outstanding common shares on a pro-rata basis based on the number of shares
properly tendered (Pro-Ration Factor). The final results of the tender offer are
provided in the table below.



                                                                                                 Number of

                             8. DISTRIBUTION POLICY

As previously announced, the Fund's Board of Trustees approved the commencement,
effective with the monthly distribution declared in February 2017 and continuing
for all distributions declared during the following eleven months, of a
distribution policy that provides for the declaration of monthly distributions
to common shareholders of the Fund at an annual minimum fixed rate of 8.5% based
on the Fund's average monthly NAV per share over the prior 12 months. Under the
distribution policy, monthly distributions may be sourced from income, paid-in
capital, and/or capital gains, if any.

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

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

TO THE SHAREHOLDERS AND THE BOARD OF TRUSTEES OF FIRST TRUST HIGH INCOME
LONG/SHORT FUND:

We have audited the accompanying statement of assets and liabilities of First
Trust High Income Long/Short Fund (the "Fund"), including the portfolio of
investments, as of October 31, 2017, and the related statements of operations
and cash flows for the year then ended, the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2017, by correspondence with the Fund's
custodian, brokers, and agent banks; when replies were not received from
brokers, we performed other auditing procedures. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of First
Trust High Income Long/Short Fund as of October 31, 2017, the results of its
operations and its cash flows for the year then ended, the changes in its net
assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.

ADDITIONAL INFORMATION

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          OCTOBER 31, 2017 (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.

                              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


                                                                         Page 33

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

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          OCTOBER 31, 2017 (UNAUDITED)


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 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.

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.

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          OCTOBER 31, 2017 (UNAUDITED)

                      ADVISORY AND SUB-ADVISORY AGREEMENTS

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

The Board of Trustees (the "Board") of First Trust High Income Long/Short Fund
(the "Fund"), including the Independent Trustees, unanimously approved the
continuation of the Investment Management Agreement (the "Advisory Agreement")
between the Fund and First Trust Advisors L.P. (the "Advisor") and the
Investment Sub Advisory Agreement (the "Sub Advisory Agreement" and together
with the Advisory Agreement, the "Agreements") among the Fund, the Advisor and
MacKay Shields LLC (the "Sub-Advisor") for a one-year period ending June 30,
2018 at a meeting held on June 12, 2017. The Board determined that the
continuation of the Agreements is in the best interests of the Fund in light of
the extent and quality of the services provided and such other matters as the
Board considered to be relevant in the exercise of its reasonable business
judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. At meetings held on April 24, 2017 and June 12, 2017, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor and the Sub-Advisor responding to requests for information from counsel
to the Independent Trustees that, among other things, outlined the services
provided by the Advisor and the Sub-Advisor to the Fund (including the relevant
personnel responsible for these services and their experience); the advisory fee
rate payable by the Fund and the sub-advisory fee rate as compared to fees
charged to a peer group of funds 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 and the Sub-Advisor; expenses of the Fund as
compared to expense ratios of the funds in the MPI Peer Group; performance
information for the Fund; 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; any fall out benefits to the Advisor and the
Sub-Advisor; and information on the Advisor's and the Sub-Advisor's compliance
programs. The Board reviewed initial materials with the Advisor at the meeting
held on April 24, 2017, prior to which the Independent Trustees and their
counsel met separately to discuss the information provided by the Advisor and
the Sub-Advisor. Following the April meeting, independent legal counsel on
behalf of the Independent Trustees requested certain clarifications and
supplements to the materials provided, and the information provided in response
to those requests was considered at an executive session of the Independent
Trustees and independent legal counsel held prior to the June 12, 2017 meeting,
as well as at the meeting held that day. The Board applied its business judgment
to determine whether the arrangements between the Fund and the Advisor and among
the Fund, the Advisor and the Sub-Advisor continue to be reasonable business
arrangements from the Fund's perspective as well as from the perspective of
shareholders. The Board determined that, given the totality of the information
provided with respect to the Agreements, the Board had received sufficient
information to renew the Agreements. The Board considered that shareholders
chose to invest or remain invested in the Fund knowing that the Advisor and the
Sub-Advisor manage the Fund.

In reviewing the Agreements, the Board considered the nature, extent and quality
of the services provided by the Advisor and the Sub-Advisor under the
Agreements. With respect to the Advisory Agreement, the Board considered that
the Advisor is responsible for the overall management and administration of the
Fund and reviewed all of the services provided by the Advisor to the Fund,
including the oversight of the Sub-Advisor, as well as the background and
experience of the persons responsible for such services. The Board noted that
the Advisor oversees the Sub-Advisor's day-to-day management of the Fund's
investments, including portfolio risk monitoring and performance review. In
reviewing the services provided, the Board noted the compliance program that had
been developed by the Advisor and considered that it includes a robust program
for monitoring the Advisor's, the Sub-Advisor's and the Fund's compliance with
the 1940 Act, as well as the Fund's compliance with its investment objectives
and policies. The Board also considered a report from the advisor with respect
to its risk management functions related to the operation of the Fund. Finally,
as part of the Board's consideration of the Advisor's services, the Advisor, in
its written materials and at the April 24, 2017 meeting, described to the Board
the scope of its ongoing investment in additional infrastructure and personnel
to maintain and improve the quality of services provided to the Fund and the
other funds in the First Trust Fund Complex. With respect to the Sub-Advisory
Agreement, in addition to the written materials provided by the Sub-Advisor, at
the June 12, 2017 meeting, the Board also received a presentation from a
portfolio manager of the Sub-Advisor discussing the services that the
Sub-Advisor provides to the Fund, including the Sub-Advisor's day-to-day
management of the Fund's investments. In considering the Sub-Advisor's
management of the Fund, the Board noted the background and experience of the
Sub-Advisor's portfolio management team. In light of the information presented
and the considerations made, the Board concluded that the nature, extent and
quality of the services provided to the 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 objectives and policies.


                                                                         Page 35

ADDITIONAL INFORMATION (CONTINUED)

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          OCTOBER 31, 2017 (UNAUDITED)


The Board considered the advisory and sub-advisory fee rates payable under the
Agreements for the services provided. The Board noted that the sub-advisory fee
is paid by the Advisor from its advisory fee. The Board received and reviewed
information showing the advisory fee rates and expense ratios of the peer funds
in the MPI Peer Group, as well as advisory fee rates charged by the Advisor and
the Sub-Advisor to other fund and non-fund clients, as applicable. With respect
to the MPI Peer Group, the Board discussed with representatives of the Advisor
how the MPI Peer Group was assembled and limitations in creating a relevant peer
group for the Fund, including that (i) the Fund is unique in its composition,
which makes assembling peers with similar strategies and asset mix difficult;
(ii) peer funds may use different amounts and types of leverage with different
costs associated with them or may use no leverage, noting that the Fund uses
non-traditional leverage by shorting bonds and reinvesting the proceeds; (iii)
only two of the peer funds employ an advisor/sub-advisor management structure
with an unaffiliated sub-advisor; and (iv) some of the peer funds are part of a
larger fund complex that may allow for additional economies of scale. The Board
took these limitations into account in considering the peer data, and noted that
the advisory fee rate payable by the Fund, based on average net assets, was
above the median of the MPI Peer Group. With respect to fees charged to other
clients, the Board considered differences between the Fund and other clients
that limited their comparability. In considering the advisory fee rate overall,
the Board also considered the Advisor's statement that it seeks to meet investor
needs through innovative and value-added investment solutions and the Advisor's
description of its long-term commitment to the Fund.

The Board considered performance information for the Fund. The Board noted the
process it has established for monitoring the Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor and Sub-Advisor for the Fund. The Board determined that this process
continues to be effective for reviewing the Fund's performance. The Board
received and reviewed information comparing the Fund's performance for periods
ended December 31, 2016 to the performance of the MPI Peer Group and to that of
a benchmark index. In reviewing the Fund's performance as compared to the
performance of the MPI Peer Group, the Board took into account the limitations
described above with respect to creating a relevant peer group for the Fund.
Based on the information provided on net asset value performance, the Board
noted that the Fund underperformed the MPI Peer Group average for the one-year
period and outperformed the MPI Peer Group average for the three- and five-year
periods ended December 31, 2016. The Board also noted that the Fund
underperformed the benchmark index in the one- and three-year periods but
outperformed the benchmark index in the five-year period ended December 31,
2016. In addition, the Board considered information provided by the Advisor on
the impact of leverage on the Fund's returns, noting that the Sub-Advisor
increased leverage during 2016. The Board also received information on the
Fund's annual distribution rate as of December 31, 2016 and the Fund's average
trading discount during 2016 and comparable information for the peer group.

On the basis of all the information provided on the fees, expenses and
performance of the Fund and the ongoing oversight by the Board, the Board
concluded that the advisory and sub-advisory fees continue to be reasonable and
appropriate in light of the nature, extent and quality of the services provided
by the Advisor and the Sub-Advisor to the Fund under the Agreements.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Fund and noted the Advisor's statement that it expects its expenses to
increase over the next twelve months as the Advisor continues to make
investments in personnel and infrastructure. The Board determined that due to
the Fund's closed-end structure, the potential for realization of economies of
scale as Fund assets grow was not a material factor to be considered. The Board
considered the revenues and allocated costs (including the allocation
methodology) of the Advisor in serving as investment advisor to the Fund for the
twelve months ended December 31, 2016 and the estimated profitability level for
the Fund calculated by the Advisor based on such data, as well as complex-wide
and product-line profitability data for the same period. The Board noted the
inherent limitations in the profitability analysis and concluded that, based on
the information provided, the Advisor's profitability level for the Fund was not
unreasonable. In addition, the Board considered fall-out benefits described by
the Advisor that may be realized from its relationship with the Fund, including
the Advisor's compensation for fund reporting services pursuant to a separate
Fund Reporting Services Agreement. The Board concluded that the character and
amount of potential fall-out benefits to the Advisor were not unreasonable.

The Board noted the Sub-Advisor's expenses in providing investment services to
the Fund and considered the Sub-Advisor's statement that it will not experience
significant economies of scale based on the current level of assets of the Fund
and the level of other assets under the management of the portfolio management
team. The Board did not review the profitability of the Sub-Advisor with respect
to the Fund. The Board noted that the Advisor pays the Sub-Advisor from its
advisory fee and its understanding that the Fund's sub advisory fee rate was the
product of an arm's length negotiation. The Board concluded that the
profitability analysis for the Advisor was more relevant. The Board considered
fall-out benefits that may be realized by the Sub-Advisor from its relationship
with the Fund, noting that the Sub-Advisor did not identify any material
fall-out benefits. The Board concluded that the character and amount of
potential fall-out benefits to the Sub-Advisor were not unreasonable.

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

      from a provision of the code of ethics that applies to the registrant's

that each of them is "independent," as defined by Item 3 of Form N-CSR.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

      (a) Audit Fees (Registrant) -- The aggregate fees billed for each of the
last two fiscal years for professional services rendered by the principal
accountant for the audit of the registrant's annual financial statements or
services that are normally provided by the accountant in connection with
statutory and regulatory filings or engagements for those fiscal years were

      (b) Audit-Related Fees (Registrant) -- The aggregate fees billed in each

the fiscal year ended October 31, 2017.

      (c) Tax Fees (Registrant) -- The aggregate fees billed in each of the last

Policy, the Audit Committee (the "Committee") is responsible for the
pre-approval of all audit services and permitted non-audit services (including
the fees and terms thereof) to be performed for the Registrant by its
independent auditors. The Chairman of the Committee authorized to give such
pre-approvals on behalf of the Committee up to $25,000 and report any such
pre-approval to the full Committee.

      The Committee is also responsible for the pre-approval of the independent
auditor's engagements for non-audit services with the Registrant's adviser (not
including a sub-adviser whose role is primarily portfolio management and is
sub-contracted or overseen by another investment adviser) and any entity
controlling, controlled by or under common control with the investment adviser
that provides ongoing services to the Registrant, if the engagement relates
directly to the operations and financial reporting of the Registrant, subject to
the de minimis exceptions for non-audit services described in Rule 2-01 of
Regulation S-X. If the independent auditor has provided non-audit services to
the Registrant's adviser (other than any sub-adviser whose role is primarily
portfolio management and is sub-contracted with or overseen by another
investment adviser) and any entity controlling, controlled by or under common
control with the investment adviser that provides ongoing services to the
Registrant that were not pre-approved pursuant to the de minimis exception, the
Committee will consider whether the provision of such non-audit services is
compatible with the auditor's independence.

      (e)(2) The percentage of services described in each of paragraphs (b)
through (d) for the Registrant and the Registrant's investment adviser of this
Item that were approved by the audit committee pursuant to the pre-approval
exceptions included in paragraph (c)(7)(i)(c) or paragraph (c)(7)(ii) of Rule

                          (b)  0%
                          (c)  0%
                          (d)  0%

      (f) The percentage of hours expended on the principal accountant's
engagement to audit the registrant's financial statements for the most recent
fiscal year that were attributed to work performed by persons other than the
principal accountant's full-time, permanent employees was less than fifty
percent.

      (g) The aggregate non-audit fees billed by the registrant's accountant for
services rendered to the registrant, and rendered to the registrant's investment
adviser (not including any sub-adviser whose role is primarily portfolio
management and is subcontracted with or overseen by another investment adviser),
and any entity controlling, controlled by, or under common control with the
adviser that provides ongoing services to the registrant for the Registrant's
fiscal year ended October 31, 2016 were $5,200 for the Registrant and $13,000
for the Registrant's investment adviser and for the Registrant's fiscal year
ended October 31, 2017 were $5,200 for the Registrant and $44,000 for the
Registrant's investment adviser.

      (h) The Registrant's audit committee of its Board of Trustees has
determined that the provision of non-audit services that were rendered to the
Registrant's investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
Registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X is compatible with maintaining the principal accountant's
independence.

investment adviser founded in 1938, and serves as the sub-advisor to the

billion in assets under management.

DAN ROBERTS, PHD, EXECUTIVE MANAGING DIRECTOR, CHIEF INVESTMENT OFFICER AND HEAD
AND CHIEF INVESTMENT OFFICER OF GLOBAL FIXED INCOME DIVISION

Director (Chief of Staff) of the U.S. Congress Joint Economic Committee. Mr.

LOUIS N. COHEN, CFA, SENIOR MANAGING DIRECTOR, GLOBAL FIXED INCOME DIVISION

Mr. Cohen has 40 years of investment experience. During his career, Mr. Cohen
has served as a Core/Core Plus Portfolio Manager and was Co-Chairman of a Credit
Committee. He has extensive credit experience, beginning in a Commercial Banking
Department. He began to specialize in fixed-income in 1981, and became a
fixed-income credit manager at several major firms. With experience in the

aspects of investment management and decision-making. No one portfolio manager
is singularly responsible for any particular account. Investment decisions are
carried across all portfolios with similar guidelines. While portfolio managers
conduct their own industry-specific research, all information is continually
shared with the other members of the investment team. Additionally, portfolio
managers will cross-train to gain familiarity with other industries.

The portfolio managers within the Global Fixed Income Team generally come to a
consensus on the appropriateness of a security for inclusion or removal from the
portfolio. On the rare occasions this is not possible, Dan Roberts, as Head of
the Team, is ultimately responsible and has final decision-making power.

* The Global Fixed Income Team utilizes a team approach in all aspects of
  investment management and decision-making. No one portfolio manager is
  singularly responsible for any particular account. Information provided
  are assets and number of accounts managed by the team.

POTENTIAL CONFLICTS OF INTERESTS

Most of our clients pay us an investment advisory or management fee that is
based on the amount of assets in the clients' accounts. These are commonly
referred to as "asset-based fees". Some of our clients pay us fees calculated as
a percentage of returns, or as a percentage of the increase in net asset value.
These fees may be tied to a client-directed benchmark and may be subject to a
loss carry forward. They are commonly referred to as "performance-based fees".

The Global Fixed Income team that manages the Fund provides portfolio management
services for other MacKay Shields accounts, including: mutual funds;
institutional managed accounts; private commingled funds; and hedge funds.
Managing accounts that have a performance-based fee at the same time that we
manage accounts that only have an asset-based fee is commonly referred to as
"side-by-side management." Except for distinctions based on investment
objectives, investment guidelines and cash flow, all accounts are treated the
same, regardless of fee structure. This creates a conflict of interest by giving
us an incentive to favor those accounts for which we receive a performance-based
fee because we will receive a higher fee if their performance exceeds the
applicable benchmark. Consistent with its policy not to favor any one client
over another, MacKay Shields has the following procedures, among others: (1)
trade allocation procedures that provide for the pro rata allocation of
investment opportunities among clients in a particular strategy, with certain
exceptions; (2) a general prohibition against same day opposite direction
transactions; and (3) short sale trade procedures requiring pre-approval of
short sales and restricting certain short sales.

The Trade Allocation Policy provides that: (1) no client will be favored over
any other client; (2) trades should be pre-allocated, subject to certain
exceptions, and allocations should be in writing; and (3) MacKay Shields'
Compliance Department conducts periodic reviews of client account performance as
a function of allocation to assure that no account or group of accounts is being
preferred systematically in the allocation process. The policy contains a
procedure for limited offerings, which provides that in a limited offering, the
allocations may be pro-rata based on size of the order or account size and
within a strategy pro-rata based on account size. Under this policy, when
determining which accounts will participate in a trade, the portfolio managers
will consider various objective criteria which may include but are not limited
to: client cash limitations, actual and anticipated account inflows and
outflows, duration and/or average maturity, account size, deal size, trade lots,
existing exposure to an issuer or industry type, other concentration limits,
specific investment objectives, borrowing capacity, and other practical
limitations. If the aggregated order is filled in its entirety, it will be
allocated among clients in accordance with the target allocation. If the order
is partially filled, it will be allocated pro rata based on the allocation
methodology recorded in the trade order management system.

Our Valuation Procedures provide, among other requirements, that any fair
valuation of a security recommended by a portfolio manager be approved by two
portfolio managers from one or more other distinct portfolio management areas.
In addition, on a monthly basis, a Fair Valuation Committee meeting convenes to
review all securities that are being fair valued.

The Firm's cross trading policy provides that all cross trades must be
pre-cleared by the Compliance Department and requires, among other things, that
the transaction (i) be a purchase or sale for no consideration other than cash
payments against prompt delivery of the security, (ii) be effected at the
independent market price of the security determined in accordance with
applicable methodology; and (iii) be effected with no brokerage transaction.

Special considerations pertain to situations where one investment strategy may
conflict with another. It is the policy of MacKay that no one client be favored
over another. For example, one strategy may focus on selling certain securities
short, with the expectation of profit in the event that the prices for such
securities decrease, while another strategy may involve acquiring securities
"long". As stated above, it is the policy of MacKay that no one client be
favored over another. To effect that policy in cases where investment strategies
compete or conflict with each other, MacKay has adopted the following
procedures:

a) Each portfolio manager will determine, separately from any other managers the
securities to purchase and sell on any given day with respect to the clients and
strategies for which they are responsible.

b) In the event that the same strategy purchases or sells the same security on
the same trading day, all accounts participating in the transaction for that
security shall be average-priced (same-day trades executed on behalf of
different strategies may not be average-priced), provided, however, that short
sales for a particular security shall not be average-priced with purchases of
the same security.

c) If a portfolio manager enters a buy or sell order for the same security for
more than one client or strategy, and the orders are worked concurrently and not
completely filled, each applicable client or strategy will be allotted
securities pro-rata, in proportion to the amounts specified in the portfolio
manager's orders as described above.

(A)(3) COMPENSATION STRUCTURE OF PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBERS

INFORMATION PROVIDED AS OF OCTOBER 31, 2017.

Fixed compensation is primarily paid through a portfolio manager's annual
salary, which is paid in monthly installments in arrears. Salaries are set by
reference to a range of factors, taking account of seniority and
responsibilities and the market rate of pay for the relevant position. Annual
salaries are set at competitive levels to attract and maintain the best
professional talent. Variable or incentive compensation, both cash bonus and
deferred awards, are a significant component of total compensation for portfolio
managers at MacKay Shields. Incentive compensation received by portfolio
managers is based on both quantitative and qualitative factors. This approach
instills a strong sense of commitment towards the overall success of the firm.
Deferred awards are provided to attract, retain, motivate and reward key
personnel. As such, MacKay Shields maintains a phantom equity plan and awards
vest and pay out after several years. Thus, portfolio managers share in the
results and success of the firm.

MacKay Shields has performance-based fee arrangements with "eligible clients"
(as that term is defined under Rule 205-3 of the Advisers Act). In these cases a
portion of these performance-based fees may be included in the incentive program
described above.

MacKay Shields does not align the portfolio managers' compensation to the
investment performance of specific Funds or of other accounts they manage. The
compensation received by portfolio managers is based on both quantitative and
qualitative factors. The quantitative factors may include: (i) investment
performance; (ii) assets under their management; (iii) revenue and
profitability; and (iv) industry benchmarks. The qualitative factors include,
among others, leadership, adherence to the firm's policies and procedures, and
contribution to the firm's goals and objectives. To the extent that an increase
in the size of a Fund or another account managed by a portfolio manager results
in an increase in profitability, the portfolio manager's compensation may also
increase. There is no difference between the method used in determining
portfolio managers' compensation with respect to a Fund and other accounts they
manage. We do not believe the compensation structure provides an incentive for
an employee who provides services to a Fund to take undue risks in managing the
assets of the Fund.

Variable or incentive compensation, both cash bonus and deferred awards, are a
significant component of total compensation for portfolio managers at MacKay
Shields. Deferred awards are provided to attract, retain, motivate and reward
key personnel. As such, MacKay Shields maintains a phantom equity plan. For
those portfolio managers whose total compensation exceeds a pre-determined
threshold, a portion of their total compensation is paid in plan awards which
vest and pay out after several years. Thus, portfolio managers share in the
business results and success of the firm. The portfolio managers involved in
managing the Fund's investments participate in the phantom equity plan.

Receipt of an award from the phantom equity plan is conditioned upon execution
of an Executive Employment Agreements with MacKay, which include provisions
relating to fixed and variable compensation. The Executive Employment Agreements
are renewable for one year terms and can be terminated on 60 days' prior written
notice. There is also a provision for termination by MacKay for cause, as
defined in the Agreements. The Agreements contain restrictions regarding
non-solicitation of clients and non-hiring of employees following termination of
the portfolio managers' employment. None of the portfolio managers is subject to
a non-compete agreement that could potentially affect the portfolio manager's
ability to manage the Fund.

On September 15, 2015, the Fund commenced a share repurchase program for
purposes of enhancing shareholder value and reducing the discount at which the
Fund's shares trade from their net asset value. The program originally expired
on March 15, 2016, but the Board of Trustees of the Fund (the "Board") has
subsequently authorized the continuation of the Fund's share repurchase program
until March 15, 2018 authorized the continuation of the Fund's share repurchase
program. For the year ended October 31, 2017, and the year ended October 31,
2016, the Fund repurchased 13,654 and 656,620, respectively, of its shares at a
weighted-average discount of 13.69% and 15.14%, respectively, from net asset
value per share. The Fund expects to continue to repurchase its outstanding
shares as it believes such activity will further the accomplishment of the
foregoing objectives, until the earlier of (i) the repurchase of an additional
978,598 common shares (for an aggregate of 1,802,808), or (ii) March 15, 2018.

On June 14, 2017, the Fund commenced a tender offer for up to 15% of its
outstanding common shares for cash at a price per share equal to 98% of the net
asset value per share determined on the expiration date. The Fund's tender offer
expired at 5:00 p.m. New York City time on Thursday, July 13, 2017. Since the
Fund's tender offer was oversubscribed, the Fund purchased 5,284,792 (15%) of
its outstanding common shares on a pro-rata basis based on the number of shares
properly tendered.
