(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
      any 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 7/15/33. On June 12,
      2012, the holders of these units received new transferable General Motors
      Unsecured Claim (GUC) Trust Units, which were created to hold and
      administer the common stock and warrants of General Motors Company to be
      contributed to the GUC Trust under the General Motors Bankruptcy Plan of
      Reorganization.

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

(d)   Fixed-to-floating rate security. The interest rate shown reflects the
      fixed rate in effect at January 31, 2013. At a predetermined date, the
      fixed rate will change to a floating rate.

(e)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A of the Securities Act
      of 1933, as amended (the "1933 Act"), and may be resold in transactions
      exempt from registration, normally to qualified institutional buyers.
      Pursuant to procedures adopted by the 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, 2013, securities noted as such
      amounted to $190,296,487, or 26.79% of net assets.

(f)   Floating rate security. The interest rate shown reflects the rate in
      effect at January 31, 2013.

(g)   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, 2013.

(h)   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.

(i)   Non-income producing security.

(j)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of January 31, 2013,
      the aggregate gross unrealized appreciation for all securities in which
      there was an excess of value over tax cost was $56,408,690 and the
      aggregate gross unrealized depreciation for all securities in which there
      was an excess of tax cost over value was $14,362,448.

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

                    FIRST TRUST HIGH INCOME LONG/SHORT FUND
                          JANUARY 31, 2013 (UNAUDITED)


                       VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of First Trust High Income
Long/Short Fund (the "Fund") is determined daily, as of the close of regular
trading on the New York Stock Exchange ("NYSE"), normally 4:00 p.m. Eastern
time, on each day the NYSE is open for trading. If the NYSE closes early on a
valuation day, the NAV is determined as of that time. Domestic debt securities
and foreign securities are priced using data reflecting the earlier closing of
the principal markets for those securities. The NAV per Common Share is
calculated by dividing the value of all assets of the Fund (including accrued
interest and dividends), less all liabilities (including accrued expenses,
dividends declared but unpaid and any borrowings of the Fund), by the total
number of Common Shares outstanding.

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

      Corporate bonds, notes, U.S. Government Securities, Mortgage-backed
      Securities ("MBS"), Asset-backed Securities ("ABS") 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.

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

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

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

Credit default swaps, if any, are 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 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.

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

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

      Quarterly Portfolio of Investments include Senior Loans

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS - (CONTINUED)

                    FIRST TRUST HIGH INCOME LONG/SHORT FUND
                          JANUARY 31, 2013 (UNAUDITED)


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

      1)    the fundamental business data relating to the issuer;

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

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

      4)    the financial statements of the issuer;

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

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

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

      8)    the coupon payments;

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

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

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

      12)   other relevant factors.


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

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

      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, 2013, 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.

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 January 31, 2013, the Fund had no when-issued, delayed-delivery or
forward purchase commitments.

                          JANUARY 31, 2013 (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, 2013.

D. FORWARD FOREIGN CURRENCY CONTRACTS:

The Fund is subject to foreign currency risk in the normal course of pursuing
its investment objectives. Forward foreign currency contracts are agreements to
exchange one currency for another at a future date and at a specified price. The
Fund uses forward foreign currency contracts to facilitate transactions in
foreign securities and to manage the Fund's foreign currency exposure. These
contracts are valued daily, and the Fund's net equity therein, representing
unrealized gain or loss on the contracts as measured by the difference between
the forward foreign exchange rates at the dates of entry into the contracts and
the forward rates at the reporting date, is included 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.

During the period ended January 31, 2013, the open and close notional values of
forward foreign currency contracts were $245,668,005 and $(229,733,092),
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. 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.


                                                                         Page 15
