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

(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 July 31, 2015, securities noted as such amounted to
      $191,295,131 or 29.40% of net assets.

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

(d)   On October 24, 2014, Momentive Performance Materials, Inc. completed a
      Bankruptcy Plan of Reorganization. As part of the Bankruptcy Plan of
      Reorganization, the holders of Momentive Performance Materials, Inc.
      Senior Secured Lien Notes ("Senior Secured Lien Notes") scheduled to
      mature on October 15, 2020, received new Momentive Performance Materials,
      Inc. Second Priority Senior Secured Notes maturing on April 24, 2022, in
      an exchange for the existing Senior Secured Lien Notes, and received an
      escrow claim, Momentive Performance Escrow Claim. The escrow claim
      represents a claim on any cash that remains in a Fee Reserve account. It
      is unknown if any remaining cash held in the Fee Reserve account will be
      available after future legal and financial costs are paid.

(e)   This security is fair valued by the Advisor's Pricing Committee in
      accordance with procedures adopted by the Fund's Board of Trustees, and in
      accordance with the provisions of the Investment Company Act of 1940, as
      amended. At July 31, 2015, securities noted as such are valued at $2 or
      0.00% of net assets.

(f)   Pursuant to procedures adopted by the Fund's Board of Trustees, this
      security has been determined to be illiquid by the Fund's Sub-Advisor.

(g)   Non-income producing security.

(h)   Floating rate security. The interest rate shown reflects the rate in
      effect at July 31, 2015.

(i)   Perpetual maturity.

FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
PORTFOLIO OF INVESTMENTS (CONTINUED)
JULY 31, 2015 (UNAUDITED)

(j)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at July 31, 2015. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(k)   Senior Floating-Rate Loan Interests ("Senior Loans") in which the Fund
      invests pay interest at rates which are periodically predetermined by
      reference to a base lending rate plus a premium. These base lending rates
      are generally (i) the lending rate offered by one or more major European
      banks, such as the London Inter-Bank Offered Rate ("LIBOR"), (ii) the
      prime rate offered by one or more United States banks or (iii) the
      certificate of deposit rate. Certain Senior Loans are subject to a LIBOR
      floor that establishes a minimum LIBOR rate. The interest rate shown
      reflects the rate in effect at July 31, 2015. When a range of rates is
      disclosed, the Fund holds more than one contract within the same tranche
      at varying rates.

(l)   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.

(m)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of July 31, 2015, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $24,186,602 and the aggregate
      gross unrealized depreciation for all securities in which there was an
      excess of tax cost over value was $34,527,824.

NOTES TO PORTFOLIO OF INVESTMENTS

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           JULY 31, 2015 (UNAUDITED)


                                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 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, which is an investment company within the scope of Financial
Accounting Standards Board ("FASB") Accounting Standards Update 2013-08, follows
accounting and reporting guidance under FASB Accounting Standards Codification
Topic 946, "Financial Services-Investment Companies."

                     2. VALUATION AND INVESTMENT PRACTICES

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:

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

            1)    benchmark yields;

            2)    reported trades;

            3)    broker/dealer quotes;

            4)    issuer spreads;

            5)    benchmark securities;

            6)    bids and offers; and

            7)    reference data including market research publications.

      Common stocks and other equity securities listed on any national or
      foreign exchange (excluding The NASDAQ(R) Stock Market LLC ("NASDAQ") and
      the London Stock Exchange Alternative Investment Market ("AIM")) are
      valued at the last sale price on the exchange on which they are
      principally traded or, for NASDAQ and AIM securities, the official closing
      price. Securities traded on 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, if any, are fair valued using a pricing service or,
      if the pricing service does not provide a value, by quotes provided by the
      selling dealer or financial institution.

      The senior floating-rate loan interests ("Senior Loans")1 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


1 The terms "security" and "securities" used throughout the Notes to Portfolio
of Investments include Senior Loans.





NOTES TO PORTFOLIO OF INVESTMENTS (CONTINUED)

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           JULY 31, 2015 (UNAUDITED)


      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.

      Exchange-traded futures contracts are valued at the closing price in the
      market where such contracts are principally traded. If no closing price is
      available, exchange-traded futures contracts are fair valued at the mean
      of their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

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

      Fixed income and other debt securities having a remaining maturity of 60
      days or less when purchased are fair valued at cost adjusted for
      amortization of premiums and accretion of discounts (amortized cost),
      provided the Advisor's Pricing Committee has determined that the use of
      amortized cost is an appropriate reflection of fair value given market and
      issuer-specific conditions existing at the time of the determination.
      Factors that may be considered in determining the appropriateness of the
      use of amortized cost include, but are not limited to, the following:

            1)    the credit conditions in the relevant market and changes
                  thereto;

            2)    the liquidity conditions in the relevant market and changes
                  thereto;

            3)    the interest rate conditions in the relevant market and
                  changes thereto (such as significant changes in interest
                  rates);

            4)    issuer-specific conditions (such as significant credit
                  deterioration); and

            5)    any other market-based data the Advisor's Pricing Committee
                  considers relevant. In this regard, the Advisor's Pricing
                  Committee may use last-obtained market-based data to assist it
                  when valuing portfolio securities using amortized cost.

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

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

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

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

       4)   the financial statements of the borrower/issuer;

       5)   the credit quality and cash flow of the borrower/issuer, based on
            the 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:





NOTES TO PORTFOLIO OF INVESTMENTS (CONTINUED)

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                           JULY 31, 2015 (UNAUDITED)


            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 July 31, 2015, is
included with the Fund's Portfolio of Investments.

B. SECURITIES TRANSACTIONS

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.

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 July 31, 2015.

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 on the Forward Foreign Currency Contracts table in the Portfolio of
Investments. 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. 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. 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.

Credit default swap contracts are marked to market daily based upon quotations
from brokers, market makers or an independent 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.

F. FOREIGN CURRENCY

The books and records of the Fund are maintained in U.S. dollars. Foreign
currencies, investments and other assets and liabilities are translated into
U.S. dollars at the exchange rates prevailing at the end of the period.
Purchases and sales of investments and items of income and expense are
translated on the respective dates of such transactions.

G. FUTURES CONTRACTS

The Fund purchases or sells (i.e., is long or short) futures contracts to hedge
against changes in interest rates (interest rate risk). Futures contracts are
agreements between the Fund and a counterparty to buy or sell a specific
quantity of an underlying instrument at a specified price and at a specified
date. Depending on the terms of the contract, futures contracts are settled
either through physical delivery of the underlying instrument on the settlement
date or by payment of a cash settlement amount on the settlement date. Open
futures contracts can also be closed out prior to settlement by entering into an
offsetting transaction in a matching futures contract. If the Fund is not able
to enter into an offsetting transaction, the Fund will continue to be required
to maintain margin deposits on the futures contract. When the contract is closed
or expires, the Fund records a realized gain or loss equal to the difference
between the value of the contract at the time it was opened and the value at the
time it was closed or expired.

Upon entering into a futures contract, the Fund must deposit funds, called
margin, with its custodian in the name of the clearing broker equal to a
specified percentage of the current value of the contract. Open futures contacts
are marked to market daily. Pursuant to the contract, the Fund agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin.

If market conditions change unexpectedly, the Fund may not achieve the
anticipated benefits of the futures contracts and may realize a loss. The use of
futures contracts involves the risk of imperfect correlation in movements in the
price of the futures contracts, interest rates and the underlying instruments.

H. SHORT SALES

Short sales are utilized for investment and risk management purposes and are
transactions in which securities or other instruments (such as options,
forwards, futures or other derivative contracts) are sold that are not currently
owned in the Fund's portfolio. When the Fund engages in a short sale, the Fund
must borrow the security sold short and deliver the security to the
counterparty. Short selling allows the Fund to profit from a decline in a market
price to the extent such decline exceeds the transaction costs and the costs of
borrowing the securities. The Fund 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 July 31, 2015, the
Fund had $533,061 in borrowings associated with investments sold short as shown
on the Portfolio of Investments.

                           3. DERIVATIVE TRANSACTIONS

For the fiscal year-to-date period (November 1, 2014 to July 31, 2015), the
notional values of forward foreign currency contracts opened and closed were
$417,020,872 and $548,374,032, respectively.

The average volume of credit default swap contracts was $6,000,000 for the
fiscal year-to-date period (November 1, 2014 through July 31, 2015).

For the fiscal year-to-date period (November 1, 2014 to July 31, 2015), the
notional values of futures contracts opened and closed were $80,468,156 and
$99,321,275, respectively.
