PORTFOLIO OF INVESTMENTS (a) (b) - (Continued)
AUGUST 31, 2011 (UNAUDITED)


(a)   All percentages shown in the Portfolio of Investments are based on net
      assets.

(b)   All investments are available to serve as collateral on the outstanding
      loan.

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

(d)   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 base LIBOR
      rate.

(e)   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.


(f)   This Senior Loan Interest was privately rated upon issuance. The rating
      agency does not provide ongoing surveillance on the rating.

(g)   This security is fair valued 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.

(h)   This borrower has filed for protection in federal bankruptcy court.

(i)   This security is restricted and cannot be offered for public sale without
      first being registered under the Securities Act of 1933, as amended. Prior
      to registration, restricted securities may only be resold in transactions
      exempt from registration (See Note D - Restricted Investments in the
      Notes to Quarterly Portfolio of Investments).

(j)   This security is a Senior Subordinated Payment-in-Kind Election Note
      whereby 1.00% of interest per annum will be paid in cash and 13.75% of
      interest per annum shall be paid by the issuer, at its option (i) entirely
      in cash , (ii) entirely in Payment-in-Kind interest or (iii) a combination
      thereof. Interest is to be paid semi-annually; however, the issuer is in
      default and income is not being accrued.

(k)   Non-income producing security.

(l)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of August 31, 2011, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $742,367 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $34,013,006.

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

                FIRST TRUST SENIOR FLOATING RATE INCOME FUND II
                          AUGUST 31, 2011 (UNAUDITED)


                       VALUATION AND INVESTMENT PRACTICES

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of First Trust Senior Floating
Rate Income Fund II (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 Senior
Floating-Rate Loan Interests ("Senior Loans")(1) in which the Fund invests 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, trade infrequently, and information
regarding a specific Senior Loan may not be widely available or may be
incomplete. Accordingly, determinations of the fair value of Senior Loans may be
based on infrequent and dated information. Because there is less reliable and
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 broker quotes to value the Senior
Loans.

Common stocks and other securities listed on any national or foreign exchange
(excluding the NASDAQ National Market ("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. If there are no transactions on
the valuation day, the securities are valued at the mean between the most recent
bid and asked prices. Securities listed on the NASDAQ or the AIM are valued at
the official closing price. If there is no official closing price on the
valuation day, the securities are valued at the mean between the most recent bid
and asked prices. Securities traded in the over-the-counter market are valued at
their closing bid prices.

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

In the event that market quotations are not readily available, the pricing
service cannot 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. However, 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
          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.

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS - (Continued)

                FIRST TRUST SENIOR FLOATING RATE INCOME FUND II
                          AUGUST 31, 2011 (UNAUDITED)


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 securities. An active market is a market in which
         transactions for the security 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 securities in active markets.

         o  Quoted prices for identical or similar securities in markets
            that are non-active. A non-active market is a market where
            there are few transactions for the security, 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
            security (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
         security.

The inputs or methodology used for valuing securities are not necessarily an
indication of the risk associated with investing in those securities. A summary
of the inputs used to value the Fund's investments as of August 31, 2011, is
included with the Fund's Portfolio of Investments.

B. SECURITY TRANSACTIONS:

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

Securities purchased or sold 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. Due
to the nature of the Senior Loan market, the actual settlement date may not be
certain at the time of the purchase or sale for some of the Senior Loans.
Interest income on such Senior Loans is not accrued until settlement date. 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.

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 August 31, 2011.

D. RESTRICTED SECURITIES:

The Fund invests in restricted securities, which are securities that may not be
offered for public sale without first being registered under the Securities Act
of 1933, as amended (the "1933 Act"). Prior to registration, restricted
securities may only be resold in transactions exempt from registration under
Rule 144A under the 1933 Act, normally to qualified institutional investors. As
of August 31, 2011, the Fund held restricted securities as shown in the
following table. The Fund does not have the right to demand that such securities
be registered. These securities are valued according to the valuation procedures
as stated in the Portfolio Valuation footnote (Note A) and are not expressed as
a discount to the carrying value of a comparable unrestricted investment. There

ITEM 2. CONTROLS AND PROCEDURES.

   (a) The registrant's principal executive and principal financial officers, or
       persons performing similar functions, have concluded that the
       registrant's disclosure controls and procedures (as defined in Rule
       30a-3(c) under the Investment Company Act of 1940, as amended (the "1940
       Act") (17 CFR 270.30a-3(c))) are effective, as of a date within 90 days
       of the filing date of the report that includes the disclosure required by
       this paragraph, based on their evaluation of these controls and
       procedures required by Rule 30a-3(b) under the 1940 Act (17 CFR
       270.30a-3(b)) and Rules 13a-15(b) or 15d-15(b) under the Securities
       Exchange Act of 1934, as amended (17 CFR 240.13a-15(b) or 240.15d-15(b)).

   (b) There were no changes in the registrant's internal control over financial
       reporting (as defined in Rule 30a-3(d) under the 1940 Act (17 CFR
       270.30a-3(d)) that occurred during the registrant's last fiscal quarter
       that have materially affected, or are reasonably likely to materially
       affect, the registrant's internal control over financial reporting.
