                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This report contains certain forward-looking statements within the meaning of
the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934,
as amended. Forward-looking statements include statements regarding the goals,
beliefs, plans or current expectations of First Trust Advisors L.P. ("First
Trust" or the "Advisor") and/or Stonebridge Advisors LLC ("Stonebridge" or the
"Sub-Advisor") and their respective representatives, taking into account the
information currently available to them. Forward-looking statements include all
statements that do not relate solely to current or historical fact. For example,
forward-looking statements include the use of words such as "anticipate,"
"estimate," "intend," "expect," "believe," "plan," "may," "should," "would" or
other words that convey uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
First Trust Intermediate Duration Preferred & Income Fund (the "Fund") to be
materially different from any future results, performance or achievements
expressed or implied by the forward-looking statements. When evaluating the
information included in this report, you are cautioned not to place undue
reliance on these forward-looking statements, which reflect the judgment of the
Advisor and/or Sub-Advisor and their representatives only as of the date hereof.
We undertake no obligation to publicly revise or update these forward-looking
statements to reflect events and circumstances that arise after the date hereof.

                        PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objectives. The
Fund is subject to market risk, which is the possibility that the market values
of securities owned by the Fund will decline and that the value of the Fund's
shares may therefore be less than what you paid for them. Accordingly, you can
lose money by investing in the Fund. See "Risk Considerations" in the Additional
Information section of this report for a discussion of certain other risks of
investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
http://www.ftportfolios.com or speak with your financial advisor. Investment
returns, net asset value and common share price will fluctuate and Fund shares,
when sold, may be worth more or less than their original cost.

The Advisor may also periodically provide additional information on Fund
performance on the Fund's webpage at http://www.ftportfolios.com.

                            HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment in
the Fund. It includes details about the Fund and presents data and analysis that
provide insight into the Fund's performance and investment approach.

By reading the portfolio commentary by the portfolio management team of the
Fund, you may obtain an understanding of how the market environment affected the
Fund's performance. The statistical information that follows may help you

benchmarks.

It is important to keep in mind that the opinions expressed by personnel of the
Sub-Advisor are just that: informed opinions. They should not be considered to
be promises or advice. The opinions, like the statistics, cover the period
through the date on the cover of this report. The material risks of investing in
the Fund are spelled out in the prospectus, the statement of additional
information, this report and other Fund regulatory filings.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                    ANNUAL LETTER FROM THE CHAIRMAN AND CEO
                                OCTOBER 31, 2017


Dear Shareholders:

Thank you for your investment in First Trust Intermediate Duration Preferred &
Income Fund.

First Trust is pleased to provide you with the annual report which contains
detailed information about your investment for the 12 months ended October 31,
2017, including a market overview and a performance analysis for the period. We
encourage you to read this report carefully and discuss it with your financial
advisor.

The U.S. bull market continued through the November 2016 election and the first
nine months of the Trump presidency. During that period, November 8, 2016
(Election Day 2016) through October 31, 2017, the S&P 500(R) Index (the "Index")
posted a total return of 22.73%, according to Bloomberg. Ten of the eleven Index
sectors were up on a total return basis as well. Since the beginning of 2017
through October 31, 2017, the Index has closed its trading sessions at all-time
highs on 50 occasions. Finally, as of October 31, 2017, the Index has spent the
entire year in positive territory. This has only happened in 10 different years
over the past seven decades.

The current bull market, as measured from March 9, 2009 through October 31, 2017
is the second longest in history. While we are optimistic about the U.S.
economy, we are aware that no one can know how markets will perform in different
economic environments. We are also upbeat about the potential for world economic
growth turning higher. While no one can predict the future, the International
Monetary Fund sees world real gross domestic product rising by an estimated 0.5
percentage points from the 3.2% posted in 2016 to the 3.7% it is projecting for
2018.

We believe that one should invest for the long term and be prepared for market
volatility by keeping current on your portfolio and investing goals by speaking
regularly with your investment professional. It is also important to keep in
mind that past performance can never guarantee future results.

Thank you for giving First Trust the opportunity to be a part of your investment
plan. We value our relationship with you and will continue to focus on bringing
the types of investments that we believe can help you reach your financial
goals.

Sincerely,

/s/ James A. Bowen

James A. Bowen
Chairman of the Board of Trustees
Chief Executive Officer of First Trust Advisors L.P.

                                   COMMENTARY
MARKET RECAP

The fiscal year ended October 31, 2017 was a period of solid returns for the
preferred and hybrid securities markets. The period began with substantial
volatility following an increase in interest rates in the fourth quarter of 2016
from the unexpected victory of Donald Trump in the U.S. Presidential election
and continued Republican control of the U.S. Congress. Higher rates were also
supported by improving economic and employment data, which allowed the Federal
Reserve (the "Fed") to increase short-term interest rates by 0.25% twice during
the period. However, risk assets recovered and performed well throughout the
last three quarters of the period due to stabilizing long-term interest rates, a
flattening yield curve, and significant spread tightening. Contingent capital
securities ("CoCos") were the best performing part of the preferred and hybrid
securities market during the period, returning 16.78%, we believe due to the
improvement in credit quality of European banks (largest issuers of Cocos),
attractive yields and structures compared to U.S. bank tier 1 capital
securities, and the increasing investor comfort with the securities and more
stable investor base. After initial weakness during the period, the retail
preferred securities market was pushed higher by inflows into passive preferred
exchange-traded funds ("ETFs"), limited new issuance, and stable rates, which
were positive for the fixed-for-life structures that make up the majority of the
retail market. For the fiscal year ended October 31, 2017, the retail market
earned 6.58% while the institutional market earned 6.57%, according to the ICE
BofAML Fixed Rate Preferred Securities Index ("P0P1") and the ICE BofAML Capital
Securities Index ("C0CS"), respectively.

PERFORMANCE ANALYSIS

For the fiscal year ended October 31, 2017, the net asset value ("NAV") and
market price total returns for the First Trust Intermediate Duration Preferred
and Income Fund (the "Fund") were 13.85% and 18.53%, respectively. This compares
to a total return of 6.58% for the Fund's benchmark, which is a 50/50 blend of
P0P1 and C0CS. The Fund benefited from yield spread tightening and a flattening
Treasury yield curve, as the front end of the Treasury yield curve was pushed
higher by the Fed, which resulted in improvement in both fixed-to-floats and
floating-rate preferred securities.

The largest contributor to outperformance relative to the benchmark was
leverage, which added about 420 basis points ("bps") of total return performance
to the Fund. Also, security selection added to outperformance for the Fund in
both the retail and institutional markets as the Fund continued to favor
defensive security structures that appreciated from spread tightening. The Fund
also benefited through exposure to CoCos, which were not part of the benchmark
index. CoCos increased in value during the year due to several factors,
including the improvement in credit quality of European banks, attractive yields
and structures compared to U.S. bank tier 1 capital securities, and an
increasing investor base. Floating-rate securities were also a positive
contributor to relative performance as the front end of the Treasury curve and
the London Interbank Offered Rate ("LIBOR") reset higher, while the yield curve
flattened.

PORTFOLIO COMMENTARY (CONTINUED)

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                                 ANNUAL REPORT
                          OCTOBER 31, 2017 (UNAUDITED)

The Fund also employed a hedging strategy throughout the year in order to
further manage its interest rate risk. This strategy consisted of an interest
rate swap. The rising rate environment caused the hedge to add about 34 bps to
total return performance. Going forward, we continue to believe it is prudent to
maintain a conservative interest rate stance relative to the benchmark,
particularly if we are able to do so while the Fund continues to pay the highest
distribution rate of peer closed-end funds.

MARKET AND FUND OUTLOOK

The strong macro-economic backdrop, strong corporate earnings and solid
creditworthiness, particularly within financials, continue to support a risk-on
environment, in our opinion. Stable to gradually increasing rates, moderate
issuance, and the continued demand for yield continue to be positive for the
preferred and hybrid securities markets. However, we believe strong performance
across equity and credit markets and increased economic optimism has stretched
valuations of new issuance in some cases, which could become problematic if
interest rates or supply increases. Recently, weaker security structures have
come to market, but the deals were many times oversubscribed, supported by
investor demand for yield and some buyers that are indiscriminate about pricing,
in the form of passive ETFs, taking up a larger share of markets and deals. We
believe this could put pressure on distributions if higher yielding legacy
securities continue to be redeemed and replaced by lower yielding securities.

We continue to believe that the yield curve is likely to remain flat, as
short-term rates are likely to increase and may push long term rates higher. We
have long anticipated, and positioned for, a rising rate environment, and we
continue to hold the view that this process will be gradual. We believe U.S.
fiscal policy and potential tax and regulatory changes have the potential to
boost economic growth but we also believe this impact is likely to be muted and
slow given political uncertainty and the likelihood that any changes will likely
be phased in over time. We continue to focus on protecting the principal of our
investors and, as such, we believe it is prudent to protect investors against a
potential rise in interest rates through actively managing interest rate risk.

(1)   The Fund pays the fixed rate and receives the floating rate. The floating
      rate on October 31, 2017 was 1.239%.


(a)   Perpetual maturity.

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

(c)   Fixed-to-floating or fixed-to-variable rate security. The interest rate
      shown reflects the fixed rate in effect at October 31, 2017. At a
      predetermined date, the fixed rate will change to a floating rate or a
      variable rate.

(d)   Floating rate security.

(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, 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 October 31, 2017, securities noted
      as such amounted to $735,897,275 or 47.9% 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 Securities
      Act of 1933, as amended (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 Financial
      Statements).

(h)   This security is fair valued by the Advisor's Pricing Committee 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. At October 31, 2017, securities noted as such are valued at
      $15,126,120 or 1.0% of net assets.

(i)   This security's value was determined using significant unobservable inputs
      (see Note 2A - Portfolio Valuation in the Notes to Financial Statements).

(j)   This security is a contingent convertible capital security, which may be
      subject to conversion into common stock of the issuer under certain
      circumstances. At October 31, 2017, securities noted as such amounted to
      $418,741,103 or 18.9% of managed assets. Of these securities, 7.2%
      originated in emerging markets and 92.8% originated in foreign markets.

(k)   Aggregate cost for federal income tax purposes is $2,077,723,979. As of
      October 31, 2017, the aggregate gross unrealized appreciation for all
      investments in which there was an excess of value over tax cost was
      $123,423,346 and the aggregate gross unrealized depreciation for all
      investments in which there was an excess of tax cost over value was
      $24,240,455. The net unrealized appreciation was $99,182,891. The amounts
      presented are inclusive of derivative contracts.

All transfers in and out of the Levels during the period are assumed to occur on
the last day of the period at their current value. There were no transfers
between Levels at October 31, 2017.

Level 3 Par Preferred Securities are valued using broker quotes. These values
are based on unobservable and non-quantitative inputs. The Fund's Board of
Trustees has adopted valuation procedures that are utilized by the Advisor's
Pricing Committee to oversee the day-to-day valuation of the Fund's investments.
The Advisor's Pricing Committee, through the Fund's fund 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
third-party pricing service prices by comparing sales prices of the Fund's
investments to prior day third-party 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 activity of the Fund's investments measured at
fair value on a recurring basis using significant unobservable inputs (Level 3)
for the period presented.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                                OCTOBER 31, 2017


                                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 ("SEC") under the Investment Company Act of
1940, as amended. The Fund trades under the ticker symbol FPF on the New York
Stock Exchange ("NYSE").

The primary investment objective is to seek a high level of current income. The
Fund has a secondary objective of capital appreciation. The Fund seeks to
achieve its objectives by investing, under normal market conditions, at least
80% of its managed assets in preferred securities and other income producing
securities issued by U.S. and non-U.S. companies, including traditional
preferred securities, hybrid preferred securities that have investment and
economic characteristics of both preferred securities and debt securities,
floating rate and fixed-to-floating rate preferred securities, debt securities,
convertible securities and contingent convertible securities. There can be no
assurance that the Fund will achieve its investment objectives. The Fund seeks
to maintain, under normal market conditions, a duration of between three and
eight years. The Fund may not be appropriate for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The Fund is considered an investment company and follows accounting and
reporting guidance under Financial Accounting Standards Board ("FASB")
Accounting Standards Codification ("ASC") Topic 946, "Financial Services -
Investment Companies." The following is a summary of significant accounting
policies consistently followed by the Fund in the preparation of the financial
statements. The preparation of the financial statements in accordance with
accounting principles generally accepted in the United States of America ("U.S.
GAAP") requires management to make estimates and assumptions that affect the
reported amounts and disclosures in the financial statements. Actual results
could differ from those estimates.

A. PORTFOLIO VALUATION

The Fund's net asset value ("NAV") 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 is calculated by dividing the value of all
assets of the Fund (including accrued interest and dividends), less all
liabilities (including accrued expenses and 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. ("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 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 a third-party 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 fair valued at the
      mean of their most recent bid and asked price, if available, and otherwise
      at their closing bid price.

                                OCTOBER 31, 2017


      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 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 third-party pricing service is
unable to provide a market price; securities whose trading has been formally
suspended; a security whose market 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 third-party 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 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 third-party 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 October 31, 2017, is
included with the Fund's Portfolio of Investments.


                                                                         Page 19

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                                OCTOBER 31, 2017


B. SECURITIES TRANSACTIONS AND INVESTMENT INCOME

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income is recorded
on the accrual basis. Amortization of premiums and the accretion of discounts
are recorded using the effective interest method.

The Fund may hold the securities of real estate investments trusts ("REITs").
Distributions from such investments may include income, capital gains and return
of capital. The actual character of amounts received during the year is not
known until after the REITs' fiscal year end. The Fund records the character of
distributions received from the REITs during the year based on estimates
available. The characterization of distributions received by the Fund may be
subsequently revised based on information received from the REITs after their
tax reporting periods conclude.

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 October 31, 2017, the Fund held restricted
securities as shown in the following table that Stonebridge Advisors LLC
("Stonebridge" or 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. 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. Payments received or made by
the Fund for interest rate swaps are recorded in the Statement of Operations as
"Net realized gain (loss) on swap contracts." When an interest rate swap is
terminated, the Fund will record a realized gain or loss equal to the difference
between the proceeds from (or cost of) the closing transaction and the Fund's
basis in the contract, if any. Generally, the basis of the contracts, if any, is
the premium received or paid. 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.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                                OCTOBER 31, 2017


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 October 31, 2017, 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. When
the Fund enters into a swap agreement, any premium paid is included in "Swap
contracts, at value" on the Statement of Assets and Liabilities.

The Fund held interest rate swap agreements at October 31, 2017. 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.

Cash segregated as collateral for open swap contracts in the amount of
$3,927,669 is shown on the Statement of Assets and Liabilities.

E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS

Dividends from net investment income, if any, are declared and paid monthly, or
as the Board of Trustees may determine from time to time. Distributions of net
realized capital gains earned by the Fund, if any, will be distributed at least
annually.

Distributions from income and capital gains are determined in accordance with
federal income tax regulations, which may differ from U.S. GAAP. Certain capital
accounts in the financial statements are periodically adjusted for permanent
differences in order to reflect their tax character. These permanent differences
are primarily due to the varying treatment of income and gain/loss on portfolio
securities held by the Fund and have no impact on net assets or NAV per share.
Temporary differences, which arise from recognizing certain items of income,
expense and gain/loss in different periods for financial statement and tax
purposes, will reverse at some time in the future.

Permanent differences incurred during the year ended October 31, 2017, resulting
in book and tax accounting differences, have been reclassified at year end to
reflect a decrease in accumulated net investment income (loss) of $1,079,349 and
an increase in accumulated net realized gain (loss) on investments of
$1,079,349. Net assets were not affected by these reclassifications.

The tax character of distributions paid during the fiscal periods ended October
31, 2017 and 2016, was as follows:

Distributions paid from:                            2017             2016
Ordinary income..............................  $   114,847,734  $  118,413,319

As of October 31, 2017, the components of distributable earnings on a tax basis
were as follows:

Undistributed ordinary income................  $     1,956,977
Undistributed capital gains..................               --
                                               ---------------
Total undistributed earnings.................        1,956,977
Accumulated capital and other losses.........      (14,566,654)
Net unrealized appreciation (depreciation)...       99,182,891
                                               ---------------
Total accumulated earnings (losses)..........       86,573,214
Other........................................               --
Paid-in capital..............................    1,448,660,630
                                               ---------------
Net Assets...................................  $ 1,535,233,844
                                               ===============

F. INCOME TAXES

The Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, which includes distributing substantially all of its net
investment income and net realized gains to shareholders. Accordingly, no
provision has been made for federal and state income taxes. However, due to the
timing and amount of distributions, the Fund may be subject to an excise tax of
4% of the amount by which approximately 98% of the Fund's taxable income exceeds
the distributions from such taxable income for the calendar year.

The Fund intends to utilize provisions of the federal income tax laws, which
allow it to carry a realized capital loss forward indefinitely following the
year of the loss and offset such loss against any future realized capital gains.
The Fund is subject to certain limitations under U.S. tax rules on the use of
capital carryforwards and net unrealized built-in losses. These limitations
apply when there has been a 50% change in ownership. At October 31, 2017, the
Fund had capital loss carryforwards for federal income tax purposes of
$14,566,654.


                                                                         Page 21

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                                OCTOBER 31, 2017


The Fund is subject to accounting standards that establish a minimum threshold
for recognizing, and a system for measuring, the benefits of a tax position
taken or expected to be taken in a tax return. The taxable years ended 2014,
2015, 2016 and 2017 remain open to federal and state audit. As of October 31,
2017, management has evaluated the application of these standards to the Fund,
and has determined that no provision for income tax is required in the Fund's
financial statements for uncertain tax positions.

G. EXPENSES

The Fund will pay all expenses directly related to its operations.

H. NEW AND AMENDED FINANCIAL REPORTING RULES AND FORMS

On October 13, 2016, the SEC adopted new rules and forms, and amended existing
rules and forms. The new and amended rules and forms are intended to modernize
the reporting of information provided by funds and to improve the quality and
type of information that funds provide to the SEC and investors. In part, the
new and amended rules and forms amend Regulation S-X and require standardized,
enhanced disclosure about derivatives in a Fund's financial statements, as well
as other amendments. The compliance date for the amendments of Regulation S-X
was August 1, 2017 and resulted in additional disclosure for variable interest
and derivative instruments within the Portfolio of Investments. The new form
types and other rule amendments will be effective for the First Trust funds,
including the Fund, for reporting periods beginning on and after June 1, 2018.
Management is evaluating the new form types and other rule amendments that are
effective on or after June 1, 2018 to determine the impact to the Fund.

I. NEW ACCOUNTING PRONOUNCEMENT

In December 2016, FASB released accounting standards update ("ASU") 2016-19 that
makes technical changes to various sections of the ASC, including Topic 820,
Fair Value Measurement. The changes to Topic 820 are intended to clarify the
difference between a valuation approach and a valuation technique. The changes
to ASC 820-10-50-2 require a reporting entity to disclose, for Level 2 and Level
3 fair value measurements, a change in either or both a valuation approach and a
valuation technique and the reason(s) for the change. The changes to Topic 820
are effective for fiscal years, and interim periods within those fiscal years,
beginning after December 15, 2016. At this time, management is evaluating the
implications of the ASU and has not yet determined its impact on the financial
statements and disclosures.

3. INVESTMENT ADVISORY FEE, AFFILIATED TRANSACTIONS AND OTHER FEE ARRANGEMENTS

First Trust, the investment advisor to the Fund, is a limited partnership with
one limited partner, Grace Partners of DuPage L.P., and one general partner, The
Charger Corporation. The Charger Corporation is an Illinois corporation
controlled by James A. Bowen, Chief Executive Officer of First Trust. First
Trust is responsible for ongoing monitoring of the Fund's investment portfolio,
managing the Fund's business affairs and providing certain administrative
services necessary for the management of the Fund. For these investment
management services, First Trust is entitled to a monthly fee calculated at an
annual rate of 0.85% of the Fund's average daily net assets. First Trust also
provides fund reporting services to the Fund for a flat annual fee in the amount
of $9,250.

Stonebridge, a majority-owned affiliate of First Trust, serves as the Fund's
sub-advisor and manages the Fund's portfolio subject to First Trust's
supervision. The Sub-Advisor receives a monthly portfolio management fee
calculated at an annual rate of 0.425% of average daily net assets that is paid
by First Trust out of its investment advisory fee.

First Trust Capital Partners, LLC, an affiliate of First Trust, owns, through a
wholly-owned subsidiary, a 51% ownership interest in Stonebridge.

Brown Brothers Harriman & Co. ("BBH") serves as the Fund's administrator, fund
accountant and custodian in accordance with certain fee arrangements. As
administrator and fund accountant, BBH is responsible for providing certain
administrative and accounting services to the Fund, including maintaining the
Fund's books of account, records of the Fund's securities transactions, and
certain other books and records. As custodian, BBH is responsible for custody of
the Fund's assets.

Computershare, Inc. serves as the Fund's transfer agent in accordance with
certain fee arrangements. As transfer agent, Computershare, Inc. is responsible
for maintaining shareholder records for the Fund.

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid a fixed annual
retainer that is allocated equally among each fund in the First Trust Fund
Complex. Each Independent Trustee is also paid an annual per fund fee that
varies based on whether the fund is a closed-end or other actively managed fund,
or is an index fund.

The average volume of interest rates swaps held was $165,000,000 for the year
ended October 31, 2017.

The Fund does not have the right to offset financial assets and financial
liabilities related to swap contracts on the Statement of Assets and
Liabilities.

                                 6. BORROWINGS

The Fund entered into a credit agreement with The Bank of Nova Scotia that has a
maximum commitment amount of $725,000,000.

The borrowing rate under the facility is equal to the 1-month LIBOR plus 75
basis points. In addition, under the facility, the Fund pays a commitment fee of
0.15% on the undrawn amount of such facility on any date that the loan balance
is less than 50% of the total commitment amount. The average amount outstanding
between November 1, 2016 and October 31, 2017, was $656,712,329 with a weighted
average interest rate of 1.74%. As of October 31, 2017, the Fund had outstanding
borrowings of $680,000,000, which approximates fair value, under this committed
facility agreement. The borrowings are categorized as Level 2 within the fair
value hierarchy. The high and low annual interest rates for the year ended
October 31, 2017, were 1.99% and 1.28%, respectively. The interest rate at
October 31, 2017, was 1.99%.

                               7. INDEMNIFICATION

The Fund has a variety of indemnification obligations under contracts with its
service providers. The Fund's maximum exposure under these arrangements is
unknown. However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

                              8. SUBSEQUENT EVENTS

Management has evaluated the impact of all subsequent events on the Fund through
the date the financial statements were issued, and has determined there were no
subsequent events requiring recognition or disclosure in the financial
statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF FIRST TRUST INTERMEDIATE DURATION
PREFERRED & INCOME FUND:

We have audited the accompanying statement of assets and liabilities of First
Trust Intermediate Duration Preferred & Income Fund (the "Fund"), including the
portfolio of investments, as of October 31, 2017, and the related statements of
operations and cash flows for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods presented. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2017, by correspondence with the Fund's
custodian and brokers; when replies were not received from brokers, we performed
other auditing procedures. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of First
Trust Intermediate Duration Preferred & Income Fund as of October 31, 2017, the
results of its operations and its cash flows for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and the financial highlights for each of the periods presented, in conformity
with accounting principles generally accepted in the United States of America.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          OCTOBER 31, 2017 (UNAUDITED)


                           DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your
Common Shares with a brokerage firm that participates in the Fund's Dividend
Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund,
to receive cash distributions, all dividends, including any capital gain
distributions, on your Common Shares will be automatically reinvested by
Computershare Trust Company, N.A. (the "Plan Agent"), in additional Common
Shares under the Plan. If you elect to receive cash distributions, you will
receive all distributions in cash paid by check mailed directly to you by the
Plan Agent, as the dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will
receive will be determined as follows:

      (1)   If Common Shares are trading at or above net asset value ("NAV") at
            the time of valuation, the Fund will issue new shares at a price
            equal to the greater of (i) NAV per Common Share on that date or
            (ii) 95% of the market price on that date.


      (2)   If Common Shares are trading below NAV at the time of valuation, the
            Plan Agent will receive the dividend or distribution in cash and
            will purchase Common Shares in the open market, on the NYSE or
            elsewhere, for the participants' accounts. It is possible that the
            market price for the Common Shares may increase before the Plan
            Agent has completed its purchases. Therefore, the average purchase
            price per share paid by the Plan Agent may exceed the market price
            at the time of valuation, resulting in the purchase of fewer shares
            than if the dividend or distribution had been paid in Common Shares
            issued by the Fund. The Plan Agent will use all dividends and
            distributions received in cash to purchase Common Shares in the open
            market within 30 days of the valuation date except where temporary
            curtailment or suspension of purchases is necessary to comply with
            federal securities laws. Interest will not be paid on any uninvested
            cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving
written notice to the Plan Agent, or by telephone at (866) 340-1104, in
accordance with such reasonable requirements as the Plan Agent and the Fund may
agree upon. If you withdraw or the Plan is terminated, you will receive a
certificate for each whole share in your account under the Plan, and you will
receive a cash payment for any fraction of a share in your account. If you wish,
the Plan Agent will sell your shares and send you the proceeds, minus brokerage
commissions.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives
written confirmation of all transactions in the accounts, including information
you may need for tax records. Common Shares in your account will be held by the
Plan Agent in non-certificated form. The Plan Agent will forward to each
participant any proxy solicitation material and will vote any shares so held
only in accordance with proxies returned to the Fund. Any proxy you receive will
include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions
in Common Shares. However, all participants will pay a pro rata share of
brokerage commissions incurred by the Plan Agent when it makes open market
purchases.

Automatically reinvesting dividends and distributions does not mean that you do
not have to pay income taxes due upon receiving dividends and distributions.
Capital gains and income are realized although cash is not received by you.
Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate
in the Plan, you will not be able to participate in the Plan and any dividend
reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of
the Board of Trustees the change is warranted. There is no direct service charge
to participants in the Plan; however, the Fund reserves the right to amend the
Plan to include a service charge payable by the participants. Additional
information about the Plan may be obtained by writing Computershare, Inc., P.O.
Box 505000, Louisville, KY 40233-5000.

                              RISK CONSIDERATIONS

Risks are inherent in all investing. The following summarizes some, but not all,
of the risks that should be considered for the Fund. For additional information
about the risks associated with investing in the Fund, please see the Fund's
prospectus and statement of additional information, as well as other Fund
regulatory filings.

INVESTMENT AND MARKET RISK: An investment in the Fund's common shares ("Common
Shares") is subject to investment risk, including the possible loss of the
entire principal invested. Common Shares at any point in time may be worth less
than the original investment, even after taking into account the reinvestment of
Fund dividends and distributions. The Fund utilizes leverage, which magnifies
investment risk.

PREFERRED/HYBRID PREFERRED AND DEBT SECURITIES RISK: Preferred/hybrid preferred
and debt securities in which the Fund invests are subject to various risks,
including credit risk, interest rate risk, call/prepayment risk and reinvestment
risk, as described below. In addition, preferred and hybrid preferred securities
are subject to certain other risks, including deferral and omission risk,
subordination risk, limited voting rights risk and special redemption rights
risk.

CREDIT AND BELOW INVESTMENT GRADE SECURITIES RISK: The Fund is subject to credit
risk, which is the risk that an issuer of a security may be unable or unwilling
to make dividend, interest and principal payments when due and the related risk
that the value of a security may decline because of concerns about the issuer's
ability or willingness to make such payments. Credit risk may be heightened for
the Fund because it invests in below investment grade securities, which involve
greater risks than investment grade securities, including the possibility of
dividend or interest deferral, default or bankruptcy.

LEVERAGE RISK: The use of leverage by the Fund can magnify the effect of any
losses. If the income and gains from the securities and investments purchased
with leverage proceeds do not cover the cost of leverage, the return to the
Common Shares will be less than if leverage had not been used. Moreover,
leverage involves risks and special considerations for holders of Common Shares
including the likelihood of greater volatility of net asset value and market
price of the Common Shares than a comparable portfolio without leverage, and the
risk that fluctuations in interest rates on reverse repurchase agreements,
borrowings and short-term debt or in the dividend rates on any preferred shares
of the Fund that the Fund may pay will reduce the return to the holders of
Common Shares or will result in fluctuations in the dividends paid on the Common
Shares. There is no assurance that a leveraging strategy will be successful.
Although the Fund seeks to maintain a duration, under normal market
circumstances, excluding the effects of leverage, of between three and eight
years, if the effect of the Fund's use of leverage was included in calculating
duration, it could result in a longer duration for the Fund.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          OCTOBER 31, 2017 (UNAUDITED)


CALL/PREPAYMENT AND REINVESTMENT RISK: If an issuer of a security exercises an
option to redeem its issue at par or prepay principal earlier than scheduled,
the Fund may be forced to reinvest in lower yielding securities. A decline in
income could affect the Common Shares' market price or the overall return of the
Fund.

DURATION RISK: The Fund seeks to maintain, under normal market conditions, a
duration, excluding the effects of leverage, of between three and eight years.
Various techniques may be used to shorten or lengthen the Fund's duration.
Securities with longer durations tend to be more sensitive to interest rate (or
yield) changes than securities with shorter durations. The duration of a
security will be expected to change over time with changes in market factors and
time to maturity.

RISKS OF CONCENTRATION IN THE FINANCIALS SECTOR: Because the Fund invests 25% or
more of its managed assets in the financial sector, it will be more susceptible
to adverse economic or regulatory occurrences affecting this sector, such as
changes in interest rates, loan concentration and competition.

INTEREST RATE RISK: The Fund is subject to interest rate risk, which is the risk
that the preferred and debt securities in which the Fund invests will decline in
value because of rising market interest rates.

FLOATING RATE AND FIXED-TO-FLOATING RATE SECURITIES RISK: The market value of
floating rate and fixed-to-floating rate securities may fall in a declining
interest rate environment and may also fall in a rising interest rate
environment if there is a lag between the rise in interest rates and the
interest rate reset. A secondary risk associated with declining interest rates
is the risk that income earned by the Fund on floating rate and
fixed-to-floating rate securities may decline due to lower coupon payments on
floating-rate securities.

CONVERTIBLE SECURITIES/CONTINGENT CONVERTIBLE SECURITIES RISK: The market value
of convertible securities tends to decline as interest rates increase and,
conversely, tends to increase as interest rates decline. In addition, because of
the conversion feature, the market value of convertible securities tends to vary
with fluctuations in the market value of the underlying common stock.

Contingent convertible securities ("CoCos") provide for mandatory conversion
into common stock of the issuer under certain circumstances. Since the common
stock of the issuer may not pay a dividend, investors in these instruments could
experience a reduced income rate, potentially to zero; and conversion would
deepen the subordination of the investor, hence worsening standing in a
bankruptcy. In addition, some such instruments have a set stock conversion rate
that would cause a reduction in value of the security if the price of the stock
is below the conversion price on the conversion date. CoCos may be considered to
be high yield securities (a.k.a. "junk" bonds) and, to the extent a CoCo held by
the Fund undergoes a write down, the Fund may lose some or all of its original
investment in the CoCo. Performance of a CoCo issuer may, in general, be
correlated with the performance of other CoCo issuers. As a result, negative
information regarding one CoCo issuer may cause a decline in value of other CoCo
issuers. Subordinate securities such as CoCos are more likely to experience
credit loss than non subordinate securities of the same issuer - even if the
CoCos do not convert to equity securities. Any losses incurred by subordinate
securities, such as CoCos, are likely to be proportionately greater than
non-subordinate securities and any recovery of principal and interest of
subordinate may take more time. As a result, any perceived decline in credit
worthiness of a CoCo issuer is likely to have a greater impact on the CoCo, as a
subordinate security.

FOREIGN (NON-U.S.) SECURITIES RISK: Investing in securities of non-U.S. issuers
may involve certain risks not typically associated with investing in securities
of U.S. issuers. These risks include: (i) there may be less publicly available
information about non-U.S. issuers or markets due to less rigorous disclosure or
accounting standards or regulatory practices; (ii) non-U.S. markets may be
smaller, less liquid and more volatile than the U.S. market; (iii) potential
adverse effects of fluctuations in currency exchange rates or controls on the
value of the Fund's investments; (iv) the economies of non U.S. countries may
grow at slower rates than expected or may experience a downturn or recession;
(v) the impact of economic, political, social or diplomatic events; (vi) certain
non-U.S. countries may impose restrictions on the ability of non U.S. issuers to
make payments of principal and interest to investors located in the United
States due to blockage of non-U.S. currency exchanges or otherwise; and (vii)
withholding and other non-U.S. taxes may decrease the Fund's return.

ILLIQUID AND RESTRICTED SECURITIES RISK: The Fund may invest up to 25% of its
Managed Assets in illiquid securities and may able invest, without limit, in
unregistered or otherwise restricted securities. Investment of the Fund's assets
in illiquid and restricted securities may restrict the Fund's ability to take
advantage of market opportunities. Illiquid and restricted securities may be
difficult to dispose of at a fair price at the times when the Fund believes it
is desirable to do so. The market price of illiquid and restricted securities
generally is more volatile than that of more liquid securities, which may
adversely affect the price that the Fund pays for or recovers upon the sale of
such securities. Illiquid and restricted securities are also more difficult to
value, especially in challenging markets. The risks associated with illiquid and
restricted securities may be particularly acute in situations in which the
Fund's operations require cash and could result in the Fund borrowing to meet
its short-term needs or incurring losses on the sale of illiquid or restricted
securities.


                                                                         Page 27

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          OCTOBER 31, 2017 (UNAUDITED)


                      ADVISORY AND SUB-ADVISORY AGREEMENTS

BOARD CONSIDERATIONS REGARDING APPROVAL OF CONTINUATION OF INVESTMENT MANAGEMENT
AND INVESTMENT SUB-ADVISORY AGREEMENTS

The Board of Trustees of First Trust Intermediate Duration Preferred & Income
Fund (the "Fund"), including the Independent Trustees, unanimously approved the
continuation of the Investment Management Agreement (the "Advisory Agreement")
between the Fund and First Trust Advisors L.P. (the "Advisor") and the
Investment Sub Advisory Agreement (the "Sub Advisory Agreement" and together
with the Advisory Agreement, the "Agreements") among the Fund, the Advisor and
Stonebridge Advisors LLC (the "Sub-Advisor") for a one-year period ending June
30, 2018 at a meeting held on June 12, 2017. The Board determined that the
continuation of the Agreements is in the best interests of the Fund in light of
the extent and quality of the services provided and such other matters as the
Board considered to be relevant in the exercise of its reasonable business
judgment.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisors with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. At meetings held on April 24, 2017 and June 12, 2017, the
Board, including the Independent Trustees, reviewed materials provided by the
Advisor and the Sub-Advisor responding to requests for information from counsel
to the Independent Trustees that, among other things, outlined the services
provided by the Advisor and the Sub-Advisor to the Fund (including the relevant
personnel responsible for these services and their experience); the advisory fee
rate payable by the Fund and the sub-advisory fee rate as compared to fees
charged to a peer group of funds compiled by Management Practice, Inc. ("MPI"),
an independent source (the "MPI Peer Group"), and as compared to fees charged to
other clients of the Advisor and the Sub-Advisor; expenses of the Fund as
compared to expense ratios of the funds in the MPI Peer Group; performance
information for the Fund; the nature of expenses incurred in providing services
to the Fund and the potential for economies of scale, if any; financial data on
the Advisor and the Sub-Advisor; any fall out benefits to the Advisor and its
affiliate, First Trust Capital Partners, LLC ("FTCP"), and the Sub-Advisor; and
information on the Advisor's and the Sub-Advisor's compliance programs. The
Board reviewed initial materials with the Advisor at the meeting held on April
24, 2017, prior to which the Independent Trustees and their counsel met
separately to discuss the information provided by the Advisor and the
Sub-Advisor. Following the April meeting, independent legal counsel on behalf of
the Independent Trustees requested certain clarifications and supplements to the
materials provided, and the information provided in response to those requests
was considered at an executive session of the Independent Trustees and
independent legal counsel held prior to the June 12, 2017 meeting, as well as at
the meeting held that day. The Board applied its business judgment to determine
whether the arrangements between the Fund and the Advisor and among the Fund,
the Advisor and the Sub-Advisor continue to be reasonable business arrangements
from the Fund's perspective as well as from the perspective of shareholders. The
Board determined that, given the totality of the information provided with
respect to the Agreements, the Board had received sufficient information to
renew the Agreements. The Board considered that shareholders chose to invest or
remain invested in the Fund knowing that the Advisor and the Sub-Advisor manage
the Fund.

In reviewing the Agreements, the Board considered the nature, extent and quality
of the services provided by the Advisor and the Sub-Advisor under the
Agreements. With respect to the Advisory Agreement, the Board considered that
the Advisor is responsible for the overall management and administration of the
Fund and reviewed all of the services provided by the Advisor to the Fund,
including the oversight of the Sub-Advisor, as well as the background and
experience of the persons responsible for such services. The Board noted that
the Advisor oversees the Sub-Advisor's day-to-day management of the Fund's
investments, including portfolio risk monitoring and performance review. In
reviewing the services provided, the Board noted the compliance program that had
been developed by the Advisor and considered that it includes a robust program
for monitoring the Advisor's, the Sub-Advisor's and the Fund's compliance with
the 1940 Act, as well as the Fund's compliance with its investment objectives
and policies. The Board also considered a report from the Advisor with respect
to its risk management functions related to the operation of the Fund. Finally,
as part of the Board's consideration of the Advisor's services, the Advisor, in
its written materials and at the April 24, 2017 meeting, described to the Board
the scope of its ongoing investment in additional infrastructure and personnel
to maintain and improve the quality of services provided to the Fund and the
other funds in the First Trust Fund Complex. With respect to the Sub-Advisory
Agreement, the Board reviewed the materials provided by the Sub-Advisor and
considered the services that the Sub-Advisor provides to the Fund, including the
Sub-Advisor's day-to-day management of the Fund's investments. In considering
the Sub-Advisor's management of the Fund, the Board noted the background and
experience of the Sub-Advisor's portfolio management team and the Board's prior
meetings with members of the portfolio management team. In light of the
information presented and the considerations made, the Board concluded that the
nature, extent and quality of the services provided to the Fund by the Advisor
and the Sub-Advisor under the Agreements have been and are expected to remain
satisfactory and that the Sub-Advisor, under the oversight of the Advisor, has
managed the Fund consistent with its investment objectives and policies.

        FIRST TRUST INTERMEDIATE DURATION PREFERRED & INCOME FUND (FPF)
                          OCTOBER 31, 2017 (UNAUDITED)


The Board considered the advisory and sub-advisory fee rates payable under the
Agreements for the services provided. The Board noted that the sub-advisory fee
is paid by the Advisor from its advisory fee. The Board received and reviewed
information showing the advisory fee rates and expense ratios of the peer funds
in the MPI Peer Group, as well as advisory fee rates charged by the Advisor and
the Sub-Advisor to other fund and non-fund clients, as applicable. With respect
to the MPI Peer Group, the Board discussed with representatives of the Advisor
how the MPI Peer Group was assembled and limitations in creating a relevant peer
group for the Fund, including that (i) the Fund is unique in its composition,
which makes assembling peers with similar strategies and asset mix difficult;
(ii) peer funds may use different amounts and types of leverage with different
costs associated with them; (iii) only half of the peer funds employ an
advisor/sub-advisor management structure and none of the peer funds employs an
advisor/sub-advisor management structure with an unaffiliated sub-advisor; and
(iv) some of the peer funds are part of a larger fund complex that may allow for
additional economies of scale. The Board took these limitations into account in
considering the peer data, and noted that the advisory fee rate payable by the
Fund, based on average managed assets, was above the median of the MPI Peer
Group. With respect to fees charged to other clients, the Board considered
differences between the Fund and other clients that limited their comparability.
In considering the advisory fee rate overall, the Board also considered the
Advisor's statement that it seeks to meet investor needs through innovative and
value-added investment solutions and the Advisor's description of its long-term
commitment to the Fund.

The Board considered performance information for the Fund. The Board noted the
process it has established for monitoring the Fund's performance and portfolio
risk on an ongoing basis, which includes quarterly performance reporting from
the Advisor and Sub-Advisor for the Fund. The Board determined that this process
continues to be effective for reviewing the Fund's performance. The Board
received and reviewed information comparing the Fund's performance for periods
ended December 31, 2016 to the performance of the MPI Peer Group and to a
blended benchmark index. In reviewing the Fund's performance as compared to the
performance of the MPI Peer Group, the Board took into account the limitations
described above with respect to creating a relevant peer group for the Fund.
Based on the information provided on net asset value performance, the Board
noted that the Fund outperformed the MPI Peer Group average for the one-year
period and was at the MPI Peer Group average for the three-year period ended
December 31, 2016. The Board also noted that the Fund outperformed the blended
benchmark index for the one- and three-year periods ended December 31, 2016. In
addition, the Board considered information provided by the Advisor on the impact
of leverage on the Fund's returns. The Board also received information on the
Fund's annual distribution rate as of December 31, 2016 and the Fund's average
trading discount during 2016 and comparable information for the peer group.

On the basis of all the information provided on the fees, expenses and
performance of the Fund and the ongoing oversight by the Board, the Board
concluded that the advisory and sub advisory fees continue to be reasonable and
appropriate in light of the nature, extent and quality of the services provided
by the Advisor and the Sub Advisor to the Fund under the Agreements.

The Board considered information and discussed with the Advisor whether there
were any economies of scale in connection with providing advisory services to
the Fund and noted the Advisor's statement that it expects its expenses to
increase over the next twelve months as the Advisor continues to make
investments in personnel and infrastructure. The Board determined that due to
the Fund's closed-end structure, the potential for realization of economies of
scale as Fund assets grow was not a material factor to be considered. The Board
considered the revenues and allocated costs (including the allocation
methodology) of the Advisor in serving as investment advisor to the Fund for the
twelve months ended December 31, 2016 and the estimated profitability level for
the Fund calculated by the Advisor based on such data, as well as complex-wide
and product-line profitability data for the same period. The Board noted the
inherent limitations in the profitability analysis and concluded that, based on
the information provided, the Advisor's profitability level for the Fund was not
unreasonable. In addition, the Board considered fall-out benefits described by
the Advisor that may be realized from its relationship with the Fund. The Board
considered the ownership interest of FTCP in the Sub-Advisor and potential
fall-out benefits to the Advisor from such ownership interest. The Board noted
that in addition to the advisory fees paid by the Fund, the Advisor is
compensated for fund reporting services pursuant to a separate Fund Reporting
Services Agreement. The Board concluded that the character and amount of
potential fall-out benefits to the Advisor were not unreasonable.

The Board considered the Sub Advisor's expenses in providing investment services
to the Fund and noted the Sub-Advisor's recent hiring of additional personnel to
work on the Fund and commitment to add additional resources if assets increase.
The Board did not review the profitability of the Sub-Advisor with respect to
the Fund. The Board noted that the Advisor pays the Sub-Advisor from its
advisory fee and its understanding that the Fund's sub-advisory fee rate was the
product of an arm's length negotiation. The Board concluded that the
profitability analysis for the Advisor was more relevant. The Board considered
fall-out benefits that may be realized by the Sub-Advisor from its relationship
with the Fund, including potential fall-out benefits to the Sub-Advisor from the
ownership interest of FTCP in the Sub-Advisor. The Board noted that the
Sub-Advisor does not maintain any soft-dollar arrangements. The Board concluded
that the character and amount of potential fall-out benefits to the Sub-Advisor
were not unreasonable.

Based on all of the information considered and the conclusions reached, the
Board, including the Independent Trustees, unanimously determined that the terms
of the Agreements continue to be fair and reasonable and that the continuation
of the Agreements is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.

      described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.

      Pursuant to its charter and its Audit and Non-Audit Services Pre-Approval
Policy, the Audit Committee (the "Committee") is responsible for the
pre-approval of all audit services and permitted non-audit services (including
the fees and terms thereof) to be performed for the registrant by its
independent auditors. The Chairman of the Committee is authorized to give such
pre-approvals on behalf of the Committee up to $25,000 and report any such
pre-approval to the full Committee.

      The Committee is also responsible for the pre-approval of the independent
auditor's engagements for non-audit services with the registrant's adviser (not
including a sub-adviser whose role is primarily portfolio management and is
sub-contracted or overseen by another investment adviser) and any entity
controlling, controlled by or under common control with the investment adviser
that provides ongoing services to the registrant, if the engagement relates
directly to the operations and financial reporting of the registrant, subject to
the de minimis exceptions for non-audit services described in Rule 2-01 of
Regulation S-X. If the independent auditor has provided non-audit services to
the registrant's adviser (other than any sub-adviser whose role is primarily
portfolio management and is sub-contracted with or overseen by another
investment adviser) and any entity controlling, controlled by or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to its policies, the Committee
will consider whether the provision of such non-audit services is compatible
with the auditor's independence.

(e)(2) The percentage of services described in each of paragraphs (b) through
      (d) for the registrant and the registrant's investment adviser of this
      Item that were approved by the audit committee pursuant to the
      pre-approval exceptions included in paragraph (c)(7)(i)(c) or paragraph
      (c)(7)(ii) of Rule 2-01 of Regulation S-X are as follows:

                          (b)  0%
                          (c)  0%
                          (d)  0%

(f)   The percentage of hours expended on the principal accountant's engagement
      to audit the registrant's financial statements for the most recent fiscal
      year that were attributed to work performed by persons other than the
      principal accountant's full-time, permanent employees was less than fifty
      percent.

(g)   The aggregate non-audit fees billed by the registrant's accountant for
      services rendered to the registrant, and rendered to the registrant's
      investment adviser (not including any sub-adviser whose role is primarily
      portfolio management and is subcontracted with or overseen by another
      investment adviser), and any entity controlling, controlled by, or under
      common control with the adviser that provides ongoing services to the
      registrant for the fiscal year ended October 31, 2016 were $5,200 for the
      registrant, $13,000 for the registrant's investment adviser and $3,000 for
      the registrant's investment sub-adviser and for the registrant's fiscal
      year ended October 31, 2017 were $5,200 for the registrant, $44,000 for
      the registrant's investment adviser and $3,000 for the registrant's
      investment sub-adviser.

(h)   The registrant's audit committee of the board of directors has considered
      whether the provision of non-audit services that were rendered to the
      registrant's investment adviser (not including any sub-adviser whose role
      is primarily portfolio management and is subcontracted with or overseen by
      another investment adviser), and any entity controlling, controlled by, or
      under common control with the investment adviser that provides ongoing
      services to the registrant that were not pre-approved pursuant to
      paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
      maintaining the principal accountant's independence.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

(a)   The Registrant has a separately designated audit committee consisting of
      all the independent directors of the registrant. The members of the audit
      committee are: Thomas R. Kadlec, Niel B. Nielson, Richard E. Erickson and
