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

(a)   All or a portion of the securities are available to serve as collateral on
      the outstanding loan.

FIRST TRUST SENIOR FLOATING RATE INCOME FUND II (FCT)
PORTFOLIO OF INVESTMENTS (a) (CONTINUED)
AUGUST 31, 2015 (UNAUDITED)

(b)   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 (j) the lending rate offered by one or more major European
      banks, such as the London Interbank 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 August 31, 2015. When a range of rates is disclosed, the
      Fund holds more than one contract within the same tranche at varying
      rates.

(c)   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.

(d)   This security is fair valued by the Pricing Committee of First Trust
      Advisors L.P. (the "Advisor") in accordance with procedures adopted by the
      Fund's Board of Trustees, and in accordance with provisions of the
      Investment Company Act of 1940, as amended. At August 31, 2015, securities
      noted as such are valued at $5,898,067 or 1.54% of net assets.

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

(f)   This issuer has filed for protection in federal bankruptcy court.

(g)   This issuer is in default but interest is still being accrued by the Fund
      and paid by the issuer.

(h)   Delayed Draw Loan (see Note 2C - Unfunded Loan Commitments in the Notes to
      Portfolio of Investments).

(i)   Represents commitment fee rate on unfunded loan commitment. The commitment
      fee rate steps up at predetermined time intervals.

(j)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A under 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 the 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 August 31, 2015,
      securities noted as such amounted to $6,625,525 or 1.73% of net assets.

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

(l)   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 2D - Restricted Securities in the Notes
      to Portfolio of Investments).

(m)   Non-income producing security.

(n)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of August 31, 2015, the
      aggregate gross unrealized appreciation for all securities in which there
      was an excess of value over tax cost was $815,516 and the aggregate gross
      unrealized depreciation for all securities in which there was an excess of
      tax cost over value was $15,658,183.

All transfers in and out of the levels during the period are assumed to be
transferred on the last day of the period at their current value. There were no
transfers between levels at August 31, 2015.

Level 3 Senior Floating-Rate Loan Interests are valued by the Advisor's Pricing
Committee. Level 3 securities are valued using broker quotes. The values are
based on unobservable and non-quantitative inputs. The Fund's Board of Trustees
has adopted valuation procedures that are utilized by the Pricing Committee to
oversee the day-to-day valuation of the Fund's investments. The Advisor's
Pricing Committee, through the Fund's accounting agent, monitors daily pricing
via tolerance checks and stale and unchanged price reviews. The Advisor's
Pricing Committee also reviews monthly back testing of pricing service prices by
comparing sales prices of Fund investments to prior day pricing service prices.
Additionally, the Advisor's Pricing Committee reviews periodic information from
the Fund's third-party pricing service that compares secondary market trade
prices to their daily valuations.

The following table presents the Fund's investments measured at fair value on a
recurring basis using significant unobservable inputs (Level 3) for the period

NOTES TO PORTFOLIO OF INVESTMENTS

             FIRST TRUST SENIOR FLOATING RATE INCOME FUND II (FCT)
                          AUGUST 31, 2015 (UNAUDITED)

                                1. ORGANIZATION

First Trust Senior Floating Rate Income Fund II (the "Fund") is a diversified,
closed-end management investment company organized as a Massachusetts business
trust on March 25, 2004, 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 FCT 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:

      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, or trade infrequently, and information regarding a
      specific Senior Loan may not be widely available or may be incomplete.
      Accordingly, determinations of the fair 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.

      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.

      Corporate bonds, corporate notes and other debt securities are fair 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.

      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),

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 SENIOR FLOATING RATE INCOME FUND II (FCT)
                          AUGUST 31, 2015 (UNAUDITED)

      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 (the "1933 Act")) for which a pricing service is unable to
provide a market price; securities whose trading has been formally suspended; a
security whose market or 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 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 borrower/issuer, 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)   borrower's/issuer's competitive position within the industry;

      13)   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.





NOTES TO PORTFOLIO OF INVESTMENTS (CONTINUED)

             FIRST TRUST SENIOR FLOATING RATE INCOME FUND II (FCT)
                          AUGUST 31, 2015 (UNAUDITED)

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 August 31, 2015, 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. The Fund
had no when-issued, delayed-delivery or forward purchase commitments as of
August 31, 2015.

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 had unfunded delayed draw loan commitments of
$257,298 as of August 31, 2015.

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 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 buyers. As of August 31, 2015, 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
2A) and are not expressed as a discount to the carrying value of a comparable
unrestricted investment. There are no unrestricted investments with the same
maturity dates and yields for this issuer.
