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

(a)   All or a portion of this security serves as collateral on the outstanding
      loan.

(b)   Perpetual maturity.

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

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

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

(f)   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 (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 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 January 31, 2015, securities noted as such are valued at
      $504,681,134 or 34.39% of net assets.

(g)   This security, sold within the terms of a private placement memorandum, is
      exempt from registration upon resale under Rule 144A under the 1933 Act,
      and may be resold in transactions exempt from registration, normally to
      qualified institutional buyers (see Note 2C - Restricted Securities in the
      Notes to Quarterly Portfolio of Investments).

(h)   Aggregate cost for financial reporting purposes, which approximates the
      aggregate cost for federal income tax purposes. As of January 31, 2015,
      the aggregate gross unrealized appreciation for all securities in which
      there was an excess of value over tax cost was $52,723,119 and the
      aggregate gross unrealized depreciation for all securities in which there
      was an excess of tax cost over value was $26,197,027.

NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          JANUARY 31, 2015 (UNAUDITED)


                                1. ORGANIZATION

First Trust Intermediate Duration Preferred & Income Fund (the "Fund") is a
non-diversified, closed-end management investment company organized as a
Massachusetts business trust on February 4, 2013, 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 "FPF" 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 shares outstanding.

The Fund's investments are valued daily at market value or, in 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.'s ("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 are footnoted as such in the footnotes to the Portfolio of
Investments. The Fund's investments are valued as follows:

      Preferred 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 one or 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, notes 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.

      Securities traded in an over-the-counter market are valued at the mean of
      their most recent bid and asked price, if available, and otherwise at
      their closing bid price.

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

      Swaps are fair valued utilizing quotations provided by a third party
      pricing service or, if the pricing service does not provide a value, by
      quotes provided by the selling dealer or financial institution.

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,
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
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 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 type of security;

      2)    the size of the holding;

      3)    the initial cost of the security;

      4)    transactions in comparable securities;

      5)    price quotes from dealers and/or pricing services;

      6)    relationships among various securities;

      7)    information obtained by contacting the issuer, analysts, or the
            appropriate stock exchange;

      8)    an analysis of the issuer's financial statements; and

      9)    the existence of merger proposals or tender offers that might affect
            the value of the security.

If the securities in question are foreign securities, the following additional
information may be considered:

      1)    the value of similar foreign securities traded on other foreign
            markets;

      2)    ADR trading of similar securities;

      3)    closed-end fund trading of similar securities;

      4)    foreign currency exchange activity;

      5)    the trading prices of financial products that are tied to baskets of
            foreign securities;

      6)    factors relating to the event that precipitated the pricing problem;

      7)    whether the event is likely to recur; and

      8)    whether the effects of the event are isolated or whether they affect
            entire markets, countries or regions.


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 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 January 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.
Realized gains and losses from securities transactions are recorded on the
identified cost basis.

C. 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 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 January 31, 2015, the Fund held restricted
securities as shown in the following table that Stonebridge Advisors LLC (the
"Sub-Advisor") has deemed illiquid pursuant to procedures adopted by the Fund's

Board of Trustees. 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. 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 note (Note 2A) and are not expressed as a
discount to the carrying value of a comparable unrestricted security. There are
no unrestricted securities with the same maturity dates and yields for these
issuers.

D. 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, 2014 to January 31, 2015), the
amount of notional values of futures contracts opened and closed were $0 and
$54,498,125, respectively.

E. OPTION CONTRACTS:

The Fund may purchase or write put and call options on futures contracts and
enter into closing transactions with respect to such options to terminate an
existing position. A futures option gives the holder the right, in return for
the premium paid, to assume a long position (call) or short position (put) in a
futures contract at a specified exercise price prior to the expiration of the
option. Upon exercise of a call option, the holder acquires a long position in
the futures contract and the writer is assigned the opposite short position. In
the case of a put option, the opposite is true. Prior to exercise or expiration,
a futures option may be closed out by an offsetting purchase or sale of a
futures option of the same series.

The Fund may use options on futures contracts in connection with hedging
strategies. Generally, these strategies would be applied under the same market
and market sector conditions in which the Fund uses put and call options on
securities or indices. The purchase of put options on futures contracts is





NOTES TO QUARTERLY PORTFOLIO OF INVESTMENTS (CONTINUED)

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          JANUARY 31, 2015 (UNAUDITED)


analogous to the purchase of puts on securities or indices so as to hedge the
Fund's securities holdings against the risk of declining market prices. The
writing of a call option or the purchasing of a put option on a futures contract
constitutes a partial hedge against declining prices of securities which are
deliverable upon exercise of the futures contract. If the price at expiration of
a written call option is below the exercise price, the Fund will retain the full
amount of the option premium, which provides a partial hedge against any decline
that may have occurred in the Fund's holdings of securities. If the price when
the option is exercised is above the exercise price, however, the Fund will
incur a loss, which may be offset, in whole or in part, by the increase in the
value of the securities held by the Fund that were being hedged. Writing a put
option or purchasing a call option on a futures contract serves as a partial
hedge against an increase in the value of the securities the Fund intends to
acquire.

As with investments in futures contracts, the Fund is required to deposit and
maintain margin with respect to put and call options on futures contracts
written by them. Such margin deposits will vary depending on the nature of the
underlying futures contract (and the related initial margin requirements), the
current market value of the option, and other futures positions held by the
Fund. The Fund will earmark or set aside in a segregated account at such Fund's
custodian, liquid assets, such as cash, U.S. government securities or other
high-grade liquid debt obligations equal in value to the amount due on the
underlying obligation. Such segregated assets will be marked-to-market daily,
and additional assets will be earmarked or placed in the segregated account
whenever the total value of the earmarked or segregated assets falls below the
amount due on the underlying obligation.

The risks associated with the use of options on futures contracts include the
risk that the Fund may close out its position as a writer of an option only if a
liquid secondary market exists for such options, which cannot be assured. The
Fund's successful use of options on futures contracts depends on its
Sub-Advisor's ability to correctly predict the movement in prices of futures
contracts and the underlying instruments, which may prove to be incorrect. In
addition, there may be imperfect correlation between the instruments being
hedged and the futures contract subject to the option. Certain characteristics
of the futures market might increase the risk that movements in the prices of
futures contracts or options on futures contracts might not correlate perfectly
with movements in the prices of the investments being hedged. For example, all
participants in the futures and options on futures contracts markets are subject
to daily variation margin calls and might be compelled to liquidate futures or
options on futures contracts positions whose prices are moving unfavorably to
avoid being subject to further calls. These liquidations could increase the
price volatility of the instruments and distort the normal price relationship
between the futures or options and the investments being hedged. Also, because
of initial margin deposit requirements, there might be increased participation
by speculators in the futures markets. This participation also might cause
temporary price distortions. In addition, activities of large traders in both
the futures and securities markets involving arbitrage, "program trading," and
other investment strategies might result in temporary price distortions.

Over-the-counter options have the risk of the potential inability of
counterparties to meet the terms of their contracts. The Fund's maximum equity
price risk for purchased options is limited to the premium initially paid. In
addition, certain risks may arise upon entering into option contracts including
the risk that an illiquid secondary market will limit the Fund's ability to
close out an option contract prior to the expiration date and that a change in
the value of the option contract may not correlate exactly with changes in the
value of the securities hedged. The Fund did not hold any options as of January
31, 2015.

F . SWAP AGREEMENTS:

The Fund may enter into interest rate swap agreements. A swap is a financial
instrument that typically involves the exchange of cash flows between two
parties ("Counterparties") on specified dates (settlement dates) where the cash
flows are based on agreed upon prices, rates, etc. Swap agreements are
individually negotiated and involve the risk of the potential inability of the
Counterparties to meet the terms of the agreement. 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.

Swap agreements may increase or decrease the overall volatility of the
investments of the Fund. The performance of swap agreements may be affected by a
change in the specific interest rate, security, currency, or other factors that
determine the amounts of payments due to and from the Fund. The Fund's maximum
equity price risk to meet its future payments under swap agreements outstanding
at January 31, 2015 is equal to the total notional amount as shown on the
Portfolio of Investments. The notional amount represents the U.S. dollar value
of the contract as of the day of the opening transaction or contract reset. An
interest rate swap agreement involves the Fund's agreement to exchange a stream
of interest payments for another party's stream of cash flows. Interest rate
swaps do not involve the delivery of securities or other underlying assets or
principal. Accordingly, the risk of loss with respect to interest rate swaps is
limited to the net amount of interest payments that the Fund is contractually
obligated to make.

The average volume of interest rate swaps was $165,000,000 for the fiscal year
to date period (November 1, 2014 to January 31, 2015).
