FIRST TRUST ADVISORS L.P. ANNOUNCES PORTFOLIO MANAGER UPDATE FOR FIRST TRUST
INTERMEDIATE DURATION PREFERRED & INCOME FUND

WHEATON, IL -- (BUSINESS WIRE) -- October 23, 2018 -- First Trust Advisors L.P.
("FTA") announced today that Stonebridge Advisors LLC ("Stonebridge"),
investment sub-advisor for First Trust Intermediate Duration Preferred & Income
Fund (NYSE: FPF) (the "Fund"), will release an update on the market and the Fund
for financial advisors and investors. The update will be available THURSDAY,

SATURDAY, NOVEMBER 24, 2018. To listen to the update, follow these instructions:

The Fund is a non-diversified, closed-end management investment company that
seeks to provide a high level of current income. The Fund has a secondary
objective of capital appreciation. The Fund will seek to achieve its investment
objectives by investing in preferred and other income-producing securities.
Under normal market conditions, the Fund will invest at least 80% of its Managed
Assets in a portfolio of preferred 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.

FTA is a federally registered investment advisor and serves as the Fund's
investment advisor. FTA and its affiliate First Trust Portfolios L.P. ("FTP"), a
FINRA registered broker-dealer, are privately-held companies that provide a
variety of investment services. FTA has collective assets under management or
supervision of approximately $134 billion as of September 30, 2018 through unit
investment trusts, exchange-traded Funds, closed-end Funds, mutual Funds and
separate managed accounts. FTA is the supervisor of the First Trust unit
investment trusts, while FTP is the sponsor. FTP is also a distributor of mutual
Fund shares and exchange-traded Fund creation units. FTA and FTP are based in
Wheaton, Illinois.

Stonebridge is a registered investment advisor specializing in preferred and
hybrid securities. Stonebridge was formed in December 2004 by First Trust
Portfolios L.P. and Stonebridge Asset Management, LLC. The company had assets
under management or supervision of approximately $8.8 billion as of September
30, 2018. These assets come from separate managed accounts, unified managed
accounts, unit investment trusts, an open-end mutual Fund, actively managed
exchange-traded Funds, and the Fund.

Investment return and market value of an investment in the Fund will fluctuate.
Shares, when sold, may be worth more or less than their original cost. There can
be no assurance that the Fund's investment objectives will be achieved. The Fund
may not be appropriate for all investors.

Principal Risk Factors: The Fund is subject to risks, including the fact that it
is a non-diversified closed-end management investment company.

Preferred/hybrid and debt securities in which the Fund invests are subject to
various risks, including credit risk, interest rate risk, and call risk. Credit
risk is the risk that an issuer of a security will be unable or unwilling to
make dividend, interest and/or principal payments when due and that the value of
a security may decline as a result. 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. Interest rate risk is the risk that
the value of fixed-rate securities in the Fund will decline because of rising
market interest rates. Call risk is the risk that performance could be adversely
impacted if an issuer calls higher-yielding debt instruments held by the Fund.

Because the Fund is concentrated in the financials 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.

Investment in non-U.S. securities is subject to the risk of currency
fluctuations and to economic and political risks associated with such foreign
countries.

Use of leverage can result in additional risk and cost, and can magnify the
effect of any losses.

The risks of investing in the Fund are spelled out in the prospectus,
shareholder reports and other regulatory filings.

The information presented is not intended to constitute an investment
recommendation for, or advice to, any specific person. By providing this
information, First Trust is not undertaking to give advice in any fiduciary
capacity within the meaning of ERISA and the Internal Revenue Code. First Trust
has no knowledge of and has not been provided any information regarding any
investor. Financial advisors must determine whether particular investments are
appropriate for their clients. First Trust believes the financial advisor is a
fiduciary, is capable of evaluating investment risks independently and is
responsible for exercising independent judgment with respect to its retirement
plan clients.
