FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
PORTFOLIO OF INVESTMENTS (CONTINUED)
JANUARY 31, 2014 (UNAUDITED)


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

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

(c)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended, and may be resold in transactions exempt from
      registration, normally to qualified institutional buyers. Pursuant to
      procedures adopted by the Fund's Board of Trustees, this security has been
      determined to be liquid by MacKay Shields LLC, the Fund's sub-advisor.
      Although market instability can result in periods of increased overall
      market illiquidity, liquidity for each security is determined based on
      security specific factors and assumptions, which require subjective
      judgment. At January 31, 2014, securities noted as such amounted to
      $212,495,605, or 29.91% of net assets.

(d)   Floating rate security. The interest rate shown reflects the rate in
      effect at January 31, 2014.

(e)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at January 31, 2014. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(f)   Perpetual maturity.

(g)   Security issued by a U.S. incorporated entity, that has its par amount
      denominated in the listed foreign currency.

(h)   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 January 31, 2014. When a range of rates is
      disclosed the Fund holds more than one contract within the same tranche at
      varying rates.

(i)   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.

(j)   Non-income producing security.

(k)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of January 31, 2014,
      the aggregate gross unrealized appreciation for all securities in which
      there was an excess of value over tax cost was $61,015,492 and the
      aggregate gross unrealized depreciation for all securities in which there
      was an excess of tax cost over value was $9,459,743.

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          JANUARY 31, 2014 (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").

                     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 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 in
accordance with valuation procedures adopted by the Fund's Board of Trustees and
in accordance with provisions of the 1940 Act. Market quotations and prices used
to value the Fund's investments are primarily obtained from third party pricing
services. 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 valued at the mean of
      the most recent bid and asked prices, if available, and otherwise at their
      closing bid price.

      The loan assignments, participations and commitments ("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 infrequent and dated information. Because there is
      less reliable, objective data available, elements of judgment may play a
      greater role in valuation of Senior Loans than for other types of
      securities. Typically, Senior Loans are valued using information provided
      by a third party pricing service. The third party pricing service
      primarily uses over-the-counter pricing from dealer runs and broker quotes
      from indicative sheets to value the Senior Loans.

      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 valued at the mean of the
      most recent bid and asked prices, if available, and otherwise at their
      closing bid price. Over-the-counter futures contracts are valued at the
      mean of the most recent bid and asked prices, if available, and otherwise
      at their closing bid price.

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


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

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          JANUARY 31, 2014 (UNAUDITED)


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

      Certain securities may not be able to be priced by pre-established pricing
      methods. Such securities may be valued by the Board of Trustees or its
      delegate 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 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 a 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. The use of fair
      value prices by a Fund generally results in prices used by the Fund that
      may differ from current market quotations or official closing prices on
      the applicable exchange. A variety of factors may be considered in
      determining the fair value of such securities, including, but not limited
      to, the following:

      1)    the fundamental business data relating to the issuer;

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

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

      4)    the financial statements of the issuer;

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

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

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

      8)    the coupon payments;

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

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

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

      12)   other relevant factors.


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

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

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

            o     Quoted prices for similar investments in active markets.

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

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

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

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

The inputs or methodology used for valuing investments are not necessarily an
indication of the risk associated with investing in those investments. A summary
of the inputs used to value the Fund's investments as of January 31, 2014, 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.

                 FIRST TRUST HIGH INCOME LONG/SHORT FUND (FSD)
                          JANUARY 31, 2014 (UNAUDITED)


C. UNFUNDED LOAN COMMITMENTS:

The Fund may enter into certain credit agreements, all or a portion of which may
be unfunded. The Fund is obligated to fund these loan commitments at the
borrower's discretion. The Fund did not have unfunded delayed draw loan
commitments as of January 31, 2014.

D. FORWARD FOREIGN CURRENCY CONTRACTS:

The Fund is subject to foreign currency risk in the normal course of pursuing
its investment objectives. Forward foreign currency contracts are agreements to
exchange one currency for another at a future date and at a specified price. The
Fund uses forward foreign currency contracts to facilitate transactions in
foreign securities and to manage the Fund's foreign currency exposure. These
contracts are valued daily, and the Fund's net equity therein, representing
unrealized gain or loss on the contracts as measured by the difference between
the forward foreign exchange rates at the dates of entry into the contracts and
the forward rates at the reporting date, is included on the Schedule of Forward
Foreign Currency Contracts. Risks arise from the possible inability of
counterparties to meet the terms of their contracts and from movement in
currency and securities values and interest rates. Due to the risks, the Fund
could incur losses in excess of the net unrealized value shown on the Schedule
of Forward Foreign Currency Contracts.

For the fiscal year to date period (November 1, 2013 to January 31, 2014), the
amount of notional values of forward foreign currency contracts opened and
closed were $286,806,424 and $(286,620,590), respectively.

E. FOREIGN CURRENCY:

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

F. 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 contract and may realize a loss. The use of
futures contracts involves the risk of imperfect correlation in movements in the
price of the futures contracts, interest rates and the underlying instruments.

For the fiscal year to date period (November 1, 2013 to January 31, 2014), the
amount of notional values of futures contracts opened and closed were $
39,636,563 and $(39,484,219), respectively.

G. SHORT SALES:

Short sales are utilized for investment and risk management purposes and are
transactions in which securities or other instruments (such as options,
forwards, futures or other derivative contracts) are sold that are not currently
owned in the Fund's portfolio. When a short sale is engaged in, the security
sold short must be borrowed and delivered to the counterparty. Short selling
allows the Fund to profit from a decline in a market price to the extent such
decline exceeds the transaction costs and the costs of borrowing the securities.
The Fund will pay a fee or premium to borrow the securities and is obligated to
repay the lenders of the securities. Any dividends or interest that accrues on
the securities during the period of the loan are due to the lenders. A gain,
limited to the price at which the security was sold short, or a loss, unlimited
in size, will be recognized upon the termination of the short sale. Any such
gain or loss may be offset, completely or in part, by the change in the value of
the long portion of the Fund's portfolio. The Fund is subject to the risk it may
be unable to reacquire a security to terminate a short position except at a
price substantially in excess of the last quoted price. Also, there is the risk
that the counterparty to a short sale may fail to honor its contractual terms,
causing a loss to the Fund.
