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 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.

<sup>(1)</sup>

Most recent distribution paid through October 31, 2025. Subject to change in the future.

<sup>(2)</sup>

Distribution rates are calculated by annualizing the most recent distribution paid through the report date and then dividing by Common Share Price or NAV, as applicable, as of October 31, 2025. Subject to change in the future.

<sup>(3)</sup>

Total return is based on the combination of reinvested dividend, capital gain, and return of capital distributions, if any, at prices obtained by the Dividend Reinvestment Plan and changes in NAV per share for NAV returns and changes in Common Share Price for market value returns. Total returns do not reflect sales load and are not annualized for periods of less than one year. Past performance is not indicative of future results.

<sup>(4)</sup>

The Blended Index consists of a 30/30/30/10 blend of the ICE BofA Core Plus Fixed Rate Preferred Securities Index, the ICE BofA US Investment Grade Institutional Capital Securities Index, the ICE USD Contingent Capital Index and the ICE BofA US High Yield Institutional Capital Securities Index. The Blended Index is intended to reflect the proportional market cap of each segment of the preferred and hybrid securities market. The Blended Index returns are calculated by using the monthly returns of the indices listed above during each period shown. At the beginning of each month the indices are rebalanced to a 30/30/30/10 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Index for each period shown above. Since the ICE USD Contingent Capital Index had an inception date of December 31, 2013, the performance of the Blended Index is not available for all of the periods disclosed.

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**Annual Report**

**October 31, 2025 (Unaudited)**

![](imgbb6e1a7c5.jpg)

Performance figures assume reinvestment of all distributions and do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the indices do not actually hold a portfolio of securities and therefore do not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. The Fund's past performance does not predict future performance.

The Fund returned 11.02% for the 12-month period ended October 31, 2025, based on net asset value ("NAV"). The Fund outperformed its benchmark, which is a blend of 30% of the ICE BofA Core Plus Fixed Rate Preferred Securities Index, 30% the ICE BofA US Investment Grade Institutional Capital Securities Index, 30% of the ICE USD Contingent Capital Index and 10% of the ICE BofA US High Yield Institutional Capital Securities index, which returned 6.67% for the same period.

This outperformance was primarily driven by the Fund's leverage, security selection within $25 par fixed rate securities and Swiss banks. Leverage added over 200 basis points of performance to the Fund during the period. Long duration (10+ years) $25 pars underperformed significantly during the period. The Fund benefited from better security selection and an underweight allocation to these securities. The Fund's holdings in the Credit Suisse Group AG legal claims were the main catalyst for its outperformance within Swiss banks, as the claims repriced higher following a positive development in the Swiss court. Other factors that contributed to the Fund's outperformance were as follows:

• Overweight allocation to Canadian banks and agriculture

• Security selection within global banks including U.S. Global Systematically Important Banks, European banks and high quality Emerging Market banks

• Security selection in insurance, utilities and real estate investment trusts

The Fund also had a few factors that modestly detracted from relative performance during the same period compared to the benchmark, including the following:

• Underweight allocation to Emerging Market banks and energy

• Security selection within consumer finance

• Overweight allocation to investment companies

The Fund has a practice of seeking to maintain a relatively stable monthly distribution, which may be changed at any time. The practice has no impact on the Fund's investment strategy and may reduce the Fund's NAV. However, the Advisor believes the practice helps maintain the Fund's competitiveness and may benefit the Fund's market price and premium/discount to the Fund's NAV. The monthly distribution rate began and ended the period at $0.1375 per share. At the $0.1375 per share monthly distribution rate, the annualized distribution rate at October 31, 2025 was 8.24% at NAV and 8.66% at market price. For the twelve-month period ended October 31, 2025, 76.00% of the distributions were characterized as ordinary income and 24.00% of the distributions were characterized as return of capital. The final determination of the source and tax status of all 2025 distributions will be made after the end of 2025 and will be provided on Form 1099-DIV. The foregoing is not to be construed as tax advice. Please consult your tax advisor for further information regarding tax matters.

**Market and Fund Outlook**

The preferred and hybrid securities market strength within the past year is a testament to the underlying credit quality and attractive income relative to other asset classes, in our opinion. Tight credit spreads across the investment grade and high yield universe have driven investors with an appetite for yield to increase exposure to preferred securities and hybrids leading to fund inflows and appreciation. We believe these drivers of performance are likely to continue in the near term, however, we anticipate that the majority of total return will come in the form of income. We believe further rate cuts in the coming months will increase support for valuations in the preferred securities space.

Our investment strategy continues to limit unnecessary interest rate exposure by maintaining a neutral duration stance. We have focused on disciplined credit selection, prioritizing high-quality, less cyclical issuers to preserve portfolio stability and support consistent income. We are also maintaining a bias towards higher-yielding securities with longer call protection, while simultaneously working to minimize extension risk and capitalizing on relative valuation opportunities across market segments.

**Portfolio of Investments (Continued)**

**October 31, 2025**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;(b) This security or a portion of this security is segregated as collateral for reverse
 repurchase agreements. All of these securities are corporate bonds. The remaining contractual maturity of the agreement is between 30-90
 days. At October 31, 2025, securities noted as such are valued at $159,656,905.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Perpetual maturity.

&nbsp;&nbsp;&nbsp;&nbsp;(d) Fixed-to-variable rate security. The interest rate shown reflects the fixed rate in
 effect at October 31, 2025. At a predetermined date, the fixed rate will change to a variable rate.

&nbsp;&nbsp;&nbsp;&nbsp;(e) Floating or variable rate security.

&nbsp;&nbsp;&nbsp;&nbsp;(f) This security, sold within the terms of a private placement memorandum, is exempt
 from registration upon resale under Rule 144A of 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 2D - Restricted
 Securities in the Notes to Financial Statements).

&nbsp;&nbsp;&nbsp;&nbsp;(g) This security is fair valued by the Advisor's Pricing Committee in accordance with procedures approved by the Fund's Board of Trustees, and in accordance with the provisions of the Investment Company Act of 1940
 and rules thereunder, as amended. At October 31, 2025, securities noted as such are valued at $36,232,800 or 3.0% of net
 assets.

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

&nbsp;&nbsp;&nbsp;&nbsp;(i) 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, 2025, securities noted as such amounted
 to $504,933,880 or 27.0% of managed assets. Of these securities, 11.3% originated in emerging markets, and 88.7% originated

 from registration upon resale under Rule 144A of 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 Stonebridge Advisors LLC (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, 2025, securities noted as such amounted to $385,359,341 or 31.6% of

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**1. Organization**

First Trust Intermediate Duration Preferred & Income Fund (the "Fund") is a 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").

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" (the average daily total asset value of the Fund minus the sum of the Fund's liabilities other than the principal amount of borrowings or reverse repurchase agreements, if any), 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 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 net asset value ("NAV") of the Common Shares of the Fund is determined daily as of the close of regular trading on the NYSE, normally 4:00 p.m. Eastern time, on each day the NYSE is open for trading. If the NYSE closes early on a valuation day, the NAV is determined as of that time. Domestic debt securities and foreign securities are priced using data reflecting the earlier closing of the principal markets for those securities. The Fund's NAV per Common Share is calculated by dividing the value of all assets of the Fund (including accrued interest and dividends), less all liabilities (including accrued expenses, dividends declared but unpaid and any borrowings of the Fund), by the total number of Common Shares outstanding.

The Fund's investments are valued daily at market value or, in the absence of market value with respect to any portfolio securities, at fair value. Market value prices represent readily available market quotations such as 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 approved by the Fund's Board of Trustees, and in accordance with provisions of the 1940 Act and rules thereunder. Investments valued by the Advisor's Pricing Committee, if any, are footnoted as such in the footnotes to the Portfolio of Investments. The Fund's investments are valued as follows:

Preferred stocks, exchange traded funds and other equity securities listed on any national or foreign exchange (excluding Nasdaq, Inc. ("Nasdaq") and the London Stock Exchange Alternative Investment Market ("AIM")) are valued at the last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price. Securities traded on more than one securities exchange are valued at the last sale price or official closing price, as applicable, at the close of the securities exchange representing the primary exchange for such securities.

Capital preferred securities and other debt securities are fair valued on the basis of valuations provided by a third-party pricing service approved by the Advisor's Pricing Committee, 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.

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025**

Equity securities traded in an over-the-counter market are valued at the close price or the last trade price.

Certain securities may not be able to be priced by pre-established pricing methods. Such securities may be valued by 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 last sale price on the exchange on which they are principally traded or, for Nasdaq and AIM securities, the official closing price;

2)

the type of security;

3)

the size of the holding;

4)

the initial cost of the security;

5)

transactions in comparable securities;

6)

price quotes from dealers and/or third-party pricing services;

7)

relationships among various securities;

8)

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

9)

an analysis of the issuer's financial statements;

10)

the existence of merger proposals or tender offers that might affect the value of the security; and

11)

other relevant factors.

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

1)

the last sale price on the exchange on which they are principally traded;

2)

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

3)

ADR trading of similar securities;

4)

closed-end fund or exchange-traded fund trading of similar securities;

5)

foreign currency exchange activity;

6)

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

7)

factors relating to the event that precipitated the pricing problem;

8)

whether the event is likely to recur;

9)

whether the effects of the event are isolated or whether they affect entire markets, countries or regions; and

10)

other relevant factors.

The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly, and include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o

Quoted prices for similar investments in active markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o

Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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, 2025, is included with the Fund's Portfolio of Investments.

**B. Reverse Repurchase Agreements**

Reverse repurchase agreements were utilized as leverage for the Fund. A reverse repurchase agreement, although structured as a sale and repurchase obligation, acts as financing under which Fund assets are pledged as collateral to secure a short-term loan. Generally, the other party to the agreement makes the loan in an amount equal to a percentage of the market value of the pledged collateral. At the maturity of the reverse repurchase agreement, the loan will be repaid and the collateral will correspondingly be received back by the Fund. While used as collateral, the assets continue to pay principal and interest which are for the benefit of the Fund.

Information for the year ended October 31, 2025:

Maximum amount outstanding during the period . . . . . . . . . . . . . . . . . . . . $100,000,000

Average amount outstanding during the period\* . . . . . . . . . . . . . . . . . . . . . $100,000,000

\* The average amount outstanding during the period was calculated by adding the borrowings at the end of each day and dividing the sum by the number of days in the year ended October 31, 2025. There was $100,000,000 outstanding at October 31, 2025, which approximates fair value.

During the fiscal year ended October 31, 2025, the high and low annual interest rates ranged from 5.45% to 4.76% respectively, with a weighted average interest rate of 5.12%, on borrowings by the Fund under reverse repurchase agreements, which had interest expense that aggregated $5,184,031. The rate as of October 31, 2025 was 4.80%

**C. 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.

Securities purchased or sold on a when-issued, delayed-delivery or forward purchase commitment basis may have extended settlement period. The value of the security so purchased is subject to market fluctuations during this period. The Fund maintains liquid assets with a current value at least equal to the amount of its when-issued, delayed-delivery or forward purchase commitments until payment is made. At October 31, 2025, the Fund held $2,785,486 of when-issued or delayed-delivery securities. At October 31, 2025, the Fund had no forward purchase commitments.

The Fund may hold real estate investments trusts ("REITs"). Distributions from such investments may be comprised of return of capital, capital gains and income. 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 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.

**D. Restricted Securities**

The Fund invests in restricted securities, which are securities that may not be offered for public sale without first being registered under the 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, 2025, 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.

**E. Offsetting on the Statement of Assets and Liabilities**

Offsetting assets and liabilities requires entities to disclose both gross and net information about instruments and transactions eligible for offset on the Statement of Assets and Liabilities and disclose instruments and transactions subject to master netting or similar agreements. These disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on the Fund's financial position. The transactions subject to offsetting disclosures are derivative instruments, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions.

This disclosure, if applicable, is included within the Fund's Portfolio of Investments under the heading "Offsetting Assets and Liabilities." For financial reporting purposes, the Fund does not offset financial assets and financial liabilities that are subject to master netting arrangements ("MNAs") or similar agreements on the Statement of Assets and Liabilities. MNAs provide the right, in the event of default (including bankruptcy and insolvency), for the non-defaulting counterparty to liquidate the collateral and calculate the net exposure to the defaulting party or request additional collateral.

At October 31, 2025, reverse repurchase agreement assets and liabilities (by type) on a gross basis are as follows:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
|  |  |  |  | **Gross Amounts not Offset**<br> **in the Statement of**<br> **Assets and Liabilities** | **Gross Amounts not Offset**<br> **in the Statement of**<br> **Assets and Liabilities** |  |

**F. Dividends and Distributions to Shareholders**

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

Distributions from income and realized 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 point in the future. Permanent differences incurred during the fiscal year ended October 31, 2025, resulting in book and tax accounting differences, have been reclassified at year end to reflect a decrease in accumulated net investment income (loss) of $1,001,147, an increase in accumulated net realized gain (loss) of $198,255 and an increase to paid-in capital of $802,892.

------

**Notes to Financial Statements (Continued)**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025**

Accumulated distributable earnings (loss) consists of accumulated net investment income (loss), accumulated net realized gain (loss) on investments, and unrealized appreciation (depreciation) on investments. Net assets were not affected by this reclassification.

The tax character of distributions paid by the Fund during the fiscal years ended October 31, 2025 and 2024, was as follows:

---

| | | |
|:---|:---|:---|
| Distributions paid from: | **2025** | **2024** |
| Ordinary income | &nbsp;&nbsp; $76226124 | &nbsp;&nbsp;&nbsp; $68079843 |
| Capital gains | &nbsp;&nbsp; — | &nbsp;&nbsp;&nbsp; — |
| Return of capital | &nbsp;&nbsp; 24172791 | &nbsp;&nbsp;&nbsp; 30493637 |

As of October 31, 2025, the components of distributable earnings and net assets on a tax basis were as follows:

---

| | |
|:---|:---|
| Undistributed ordinary income | &nbsp;&nbsp; $— |
| Undistributed capital gains | &nbsp;&nbsp; — |
| Total undistributed earnings | &nbsp;&nbsp; — |
| Accumulated capital and other losses | &nbsp;&nbsp; (134141071)<br>|
| Net unrealized appreciation (depreciation) | &nbsp;&nbsp; 17862 |
| Total accumulated earnings (losses) | &nbsp;&nbsp; (134123209)<br>|
| Other | &nbsp;&nbsp; (6709251)<br>|
| Paid-in capital | &nbsp;&nbsp; 1359283438 |
| Total net assets | &nbsp;&nbsp; $1218450978 |

---

**G. 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 loss carryforwards and net unrealized built-in losses. These limitations apply when there has been a 50% change in ownership. At October 31, 2025, the Fund had non-expiring capital loss carryforwards available for federal income tax purposes of $134,141,071. At the taxable year ended October 31, 2025, the Fund utilized $20,159,849 of its capital loss carryforward.

Certain losses realized during the current fiscal year may be deferred and treated as occurring on the first day of the following fiscal year for federal income tax purposes. For the fiscal year ended October 31, 2025, the Fund did not incur any net late year ordinary losses.

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 2022, 2023, 2024, and 2025 remain open to federal and state audit. As of October 31, 2025, 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.

As of October 31, 2025, the aggregate cost, gross unrealized appreciation, gross unrealized depreciation, and net unrealized appreciation/(depreciation) on investments (including short positions and derivatives, if any) for federal income tax purposes were as follows:

---

| | | | |
|:---|:---|:---|:---|
| Tax Cost | Gross<br> Unrealized<br> Appreciation<br>| Gross<br> Unrealized<br> (Depreciation)<br>| Net Unrealized<br> Appreciation<br> (Depreciation)<br>|
| $1756799426 | $88460592 | $(88442772) | $17820 |

**H. Expenses**

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

**I. Segment Reporting**

The Fund has adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. Adoption of the standard impacted financial statement disclosures only and did not affect the Fund's financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The CODM is the President and Chief Executive Officer of the Fund. The Fund operates as a single operating segment. The Fund's income, expenses, assets, changes in net assets resulting from operations and performance are regularly monitored and assessed as a whole by the CODM responsible for oversight functions of the Fund, using the information presented in the financial statements and financial highlights.

**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 the 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 services, First Trust is entitled to a monthly fee calculated at an annual rate of 0.85% of the Fund's Managed Assets. First Trust also provides fund reporting services to the Fund for a flat annual fee in the amount of $10,000. Prior to July 1, 2025, the financial reporting fee was $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 the Fund's Managed Assets that is paid by First Trust out of its investment advisory fee.

First Trust Capital Partners, LLC, an affiliate of First Trust, owns a 51% ownership interest in Stonebridge.

The Bank of New York Mellon ("BNY") serves as the Fund's administrator, fund accountant, and custodian in accordance with certain fee arrangements. As administrator and fund accountant, BNY 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, BNY is responsible for custody of the Fund's assets. BNY is a subsidiary of The Bank of New York Mellon Corporation, a financial holding company.

Computershare, Inc. ("Computershare") serves as the Fund's transfer agent in accordance with certain fee arrangements. As transfer agent, Computershare 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, a target outcome fund or an index fund.

Additionally, the Chairs of the Audit Committee, Nominating and Governance Committee and Valuation Committee, the Vice Chair of the Audit Committee, the Lead Independent Trustee and the Vice Lead Independent Trustee are paid annual fees to serve in such capacities, with such compensation allocated pro rata among each fund in the First Trust Fund Complex based on net assets. Independent Trustees are reimbursed for travel and out-of-pocket expenses in connection with all meetings. The Committee Chairs, the Audit Committee Vice Chair, the Lead Independent Trustee and the Vice Lead Independent Trustee rotate periodically in serving in such capacities. The officers and "Interested" Trustee receive no compensation from the Fund for acting in such capacities.

**4. Purchases and Sales of Securities**

The borrowings are categorized as Level 2 within the fair value hierarchy. The high and low annual interest rates for the fiscal year ended October 31, 2025, were 5.55% and 4.86%, respectively. The interest rate at October 31, 2025, was 4.90%.

**6. 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.

**7. 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 that there were no subsequent events requiring recognition or disclosure in the financial statements that have not already been disclosed.

**Report of Independent Registered Public Accounting Firm**

**To the Shareholders and the Board of Trustees of First Trust Intermediate Duration Preferred & Income Fund:**

**Opinion on the Financial Statements and Financial Highlights**

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, 2025, the related statements of operations and cash flows for the year then ended, statements of changes in net assets for each of the two years in the period then ended, financial highlights for each of the five years in the period then ended, and the related notes (collectively referred to as the "financial statements and financial highlights"). In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Fund as of October 31, 2025, and 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 five years in the period then ended in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion**

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's financial statements and financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting 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.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. Our procedures included confirmation of securities owned as of October 31, 2025, by correspondence with the 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.

**Additional Information**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 43006, Providence, RI 02940-3006.

**Advisory and Sub-Advisory Agreements**

**Board Considerations Regarding Approval of the Continuation of the 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"). The Board approved the continuation of the Agreements for a one-year period ending June 30, 2026 at a meeting held on June 8–9, 2025. The Board determined that the continuation of the Agreements is in the best interests of the Fund in light of the nature, extent and quality of the services provided and such other matters as the Board considered to be relevant in the exercise of its 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 22, 2025 and June 8–9, 2025, 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, submitted on behalf of 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 (the

------

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

"Expense Group") and a broad peer universe of funds (the "Expense Universe"), each assembled by Broadridge Financial Solutions, Inc. ("Broadridge"), an independent source, and as compared to fees charged to other clients of the Advisor and the Sub-Advisor; the expense ratio of the Fund as compared to expense ratios of the funds in the Fund's Expense Group and Expense Universe; performance information for the Fund, including comparisons of the Fund's performance to that of one or more relevant benchmark indexes and to that of a performance group of funds and a broad performance universe of funds (the "Performance Universe"), each assembled by Broadridge; the nature of expenses incurred in providing services to the Fund and the potential for the Advisor and the Sub-Advisor to realize economies of scale, if any; profitability and other financial data for the Advisor; financial data for the Sub-Advisor; any indirect 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 22, 2025, 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, counsel to the Independent Trustees, 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 their counsel held prior to the June 8–9, 2025 meeting, as well as at the June meeting. 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. 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, policies and restrictions. 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 22, 2025 meeting, described to the Board the scope of its ongoing investment in additional personnel and infrastructure 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, including 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, policies and restrictions.

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 fee rates and expense ratios of the peer funds in the Expense Group, as well as advisory and unitary fee rates charged by the Advisor and the Sub-Advisor to other fund and non-fund clients, as applicable. With respect to the Expense Group, the Board discussed with the Advisor limitations in creating a relevant peer group for the Fund, including that (i) not all peer funds employ an advisor/sub-advisor management structure; and (ii) the Fund is unique in its composition, which makes assembling peers with similar strategies and asset mix difficult. The Board took these limitations into account in considering the peer data. Based on the information provided, the Board noted that the contractual advisory fee rate payable by the Fund, based on average managed assets, was equal to the median contractual advisory fee of the peer funds in the Expense 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 demonstrated long-term commitment to the Fund and the other funds in the First Trust Fund Complex.

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 the 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, 2024 to the performance of the funds in the Performance Universe and to that of a blended benchmark index. In reviewing the Fund's

------

**Additional Information (Continued)**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

performance as compared to the performance of the Performance Universe, 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 underperformed the Performance Universe median for the one-, three-, five- and ten-year periods ended December 31, 2024. The Board also noted that the Fund outperformed the blended benchmark index for the one-, five- and ten-year periods ended December 31, 2024 and underperformed the blended benchmark index for the three-year period ended December 31, 2024. The Board noted the Advisor's discussion of the Fund's performance at the April 22, 2025 meeting. 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 average trading discount for various periods and comparable information for a 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 at current asset levels and whether the Fund may benefit from any economies of scale. The Board noted the Advisor's statement that it believes that its expenses relating to providing advisory services to the Fund will increase during the next twelve months as the Advisor continues to build infrastructure and add new staff. The Board concluded 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, 2024 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 indirect 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 indirect 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 indirect benefits to the Advisor were not unreasonable.

The Board considered the Sub-Advisor's statements that the Sub-Advisor bears a combination of fixed and variable costs related to managing the Fund and that the Sub-Advisor would add resources as needed if it experiences significant asset growth in the future. 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 did not review the profitability of the Sub-Advisor with respect to the Fund. The Board concluded that the profitability analysis for the Advisor was more relevant. The Board considered indirect benefits that may be realized by the Sub-Advisor from its relationship with the Fund, including potential indirect benefits to the Sub-Advisor from the ownership interest of FTCP in the Sub-Advisor. The Board noted the Sub-Advisor's statements that it never accepts soft dollar arrangements and that its relationship with the Advisor has helped it build relationships with Wall Street firms that have preferred and hybrid securities trading desks, which has led to access to each of those firms' public research reports, various analysts and investment bankers on new issues. The Board concluded that the character and amount of potential indirect 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.

**Investment Objectives, Policies, Risks and Effects of Leverage**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

**Changes Occurring During the Prior Fiscal Year**

The following information is a summary of certain changes during the most recent fiscal year ended October 31, 2025. This information may not reflect all of the changes that have occurred since you purchased shares of the Fund.

During the Fund's most recent fiscal year, there were no material changes to the Fund's investment objectives or policies that have not been approved by shareholders or in the principal risk factors associated with an investment in the Fund.

**Investment Objectives** 

The Fund's primary investment objective is to seek a high level of current income. The Fund has a secondary objective of capital appreciation.

**Principal Investment Policies**

In pursuit of its investment objectives, under normal market conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund invests 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. These securities include traditional preferred securities, hybrid preferred securities and debt securities, floating rate and fixed-to-floating rate preferred securities, debt securities, convertible securities and contingent convertible securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund also invests at least 25% of its managed assets in the group of industries that are part of the financials sector as classified under the Global Industry Classification Standards, developed by MSCI, Inc. and S&P Dow Jones Indices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund seeks to invest in a portfolio of securities that has an average weighted investment grade credit quality.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund may invest up to 20% of its managed assets in common stocks, which represent residual ownership interest in issuers and include rights or warrants to purchase common stocks. The Fund may invest in common stocks of companies of any market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund may invest up to 20% of its managed assets in debt securities issued or guaranteed by the U.S. Government or its agencies or instrumentalities or by a non-U.S. Government or its agencies or instrumentalities. The Fund may invest up to 20% of its managed assets in municipal securities, which include debt obligations of states, territories or possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund may invest up to 25% of its managed assets in securities that, at the time of investment, are illiquid. The Fund also may invest, without limit, in restricted securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Fund seeks to maintain a weighted average effective duration of between three and eight years, excluding the effects of leverage. However, under certain market conditions, the Fund's duration may be longer than eight years or shorter than three years.

Percentage limitations discussed herein are as of the time of investment by the Fund and may be exceeded on a going-forward basis as a result of credit rating downgrades or market value fluctuations of the Fund's portfolio securities.

To the extent the Fund enters into derivatives transactions, it will do so pursuant to Rule 18f-4 under the 1940 Act. Rule 18f-4 requires the Fund to implement certain policies and procedures designed to manage its derivatives risks, dependent upon the Fund's level of exposure to derivative instruments.

The Fund may utilize leverage through the issuance of preferred shares of beneficial interest and/or through borrowings and/or the issuance of notes. The Fund is also permitted to use other portfolio techniques, including the use of reverse repurchase agreements, that have the economic effect of leverage. The Fund's effective leverage varies from time to time, based upon market conditions and variations in the value of the portfolio's holdings, but will not exceed 40% of the Fund's managed assets.

**Fundamental Investment Policies**

The Fund, as a fundamental policy, may not:

1. Issue senior securities, as defined in the Investment Company Act of 1940, as amended, other than (i) preferred shares which immediately after issuance will have asset coverage of at least 200%, (ii) indebtedness which immediately after issuance will have asset coverage of at least 300%, or (iii) the borrowings permitted by investment restriction (2) set forth below;

2. Borrow money, except as permitted by the Investment Company Act of 1940, as amended, the rules thereunder and interpretations thereof or pursuant to a Securities and Exchange Commission ("SEC") exemptive order;

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

3. Act as underwriter of another issuer's securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933, as amended, in connection with the purchase and sale of portfolio securities;

4. Purchase or sell real estate, but this shall not prevent the Fund from investing in securities of companies that deal in real estate or are engaged in the real estate business, including real estate investment trusts, and securities secured by real estate or interests therein and the Fund may hold and sell real estate or mortgages on real estate acquired through default, liquidation, or other distributions of an interest in real estate as a result of the Fund's ownership of such securities;

5. Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts, derivative instruments or from investing in securities or other instruments backed by physical commodities);

6. Make loans of funds or other assets, other than by entering into repurchase agreements, lending portfolio securities and through the purchase of securities in accordance with its investment objectives, policies and limitations; or

7. Concentrate (invest 25% or more of total assets) the Fund's investments in any particular industry, except that the Fund will concentrate its assets in the group of industries that are part of the financials sector; provided, however, that such limitation shall not apply to obligations issued or guaranteed by the United States government or by its agencies or instrumentalities.

The Fund does not currently intend to apply for exemptive relief from the Securities and Exchange Commission with respect to fundamental investment policy number two listed above.

The Fund may incur borrowings and/or issue series of notes or other senior securities in an amount up to 33-1/3% of its total assets (including the amount borrowed) less all liabilities other than borrowings.

The Fund's investment objectives are considered fundamental and may not be changed without the approval of the holders of a "majority of the outstanding voting securities" of the Fund, which includes common shares of beneficial interest and preferred shares of beneficial interest ("Preferred Shares"), if any, voting together as a single class, and the holders of the outstanding Preferred Shares, if any, voting as a single class. The remainder of the Fund's investment policies other than the Fund's fundamental investment restrictions listed above, including its investment strategy, are considered non-fundamental and may be changed by the Board of Trustees of the Fund without the approval of the holders of a "majority of the outstanding voting securities," provided that the holders of the voting securities of the Fund receive at least 60 days prior written notice of any change. When used with respect to particular shares of the Fund, a "majority of the outstanding voting securities" means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less.

**Principal Risks**

The Fund is a closed-end management investment company designed primarily as a long-term investment and not as a trading vehicle. The Fund is not intended to be a complete investment program and, due to the uncertainty inherent in all investments, there can be no assurance that the Fund will achieve its investment objectives. The following discussion summarizes the principal risks associated with investing in the Fund, which includes the risk that you could lose some or all of your investment in the Fund. The Fund is subject to the informational requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940 and, in accordance therewith, files reports, proxy statements and other information that is available for review.

**Contingent Convertible Securities Risk.** CoCos are hybrid securities most commonly issued by banking institutions that present risks similar to debt securities and convertible securities. CoCos are distinct in that they are intended to either convert into equity or have their principal written down upon the occurrence of certain "triggers." When an issuer's capital ratio falls below a specified trigger level, or in a regulator's discretion depending on the regulator's judgment about the issuer's solvency prospects, a CoCo may be written down, written off or converted into an equity security. Due to the contingent write-down, write-off and conversion feature, CoCos may have substantially greater risk than other securities in times of financial stress. If the trigger level is breached, the issuer's decision to write down, write off or convert a CoCo may be outside its control, and the Fund may suffer a complete loss on an investment in CoCos with no chance of recovery even if the issuer remains in existence. CoCos are usually issued in the form of subordinated debt instruments to provide the appropriate regulatory capital treatment. If an issuer liquidates, dissolves or winds-up before a conversion to equity has occurred, the rights and claims of the holders of the CoCos (such as the Fund) against the issuer generally rank junior to the claims of holders of unsubordinated obligations of the issuer. In addition, if the CoCos are converted into the issuer's underlying equity securities after a conversion event (i.e., a "trigger"), each holder will be further subordinated. CoCos also may have no stated maturity and have fully discretionary coupons. This means coupon payments can be canceled at the issuer's discretion or at the request of the relevant regulatory authority in order to help the bank absorb losses, without causing a default. In general, the value of CoCos is unpredictable and is influenced by many factors including, without limitation: the creditworthiness of the issuer and/or fluctuations in

------

**Investment Objectives, Policies, Risks and Effects of Leverage (Continued)**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

such issuer's applicable capital ratios; supply and demand for CoCos; general market conditions and available liquidity; and economic, financial and political events that affect the issuer, its particular market or the financial markets in general.

**Credit Agency Risk**. Credit ratings are determined by credit rating agencies and are only the opinions of such entities. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risk or the liquidity of securities. Any shortcomings or inefficiencies in credit rating agencies' processes for determining credit ratings may adversely affect the credit ratings of securities held by the Fund or such credit rating agency's ability to evaluate creditworthiness and, as a result, may adversely affect those securities' perceived or actual credit risk.

**Credit and Below-Investment Grade Securities Risk**. Credit risk is the risk that the issuer or other obligated party of a debt security in the Fund's portfolio will fail to pay, or it is perceived that it will fail to pay, dividends or interest and/or repay principal when due. Below-investment grade instruments, including instruments that are not rated but judged to be of comparable quality, are commonly referred to as high-yield securities or "junk" bonds and are considered speculative with respect to the issuer's capacity to pay dividends or interest and repay principal and are more susceptible to default or decline in market value than investment grade securities due to adverse economic and business developments. High-yield securities are often unsecured and subordinated to other creditors of the issuer. The market values for high-yield securities tend to be very volatile, and these securities are generally less liquid than investment grade securities. For these reasons, an investment in the Fund is subject to the following specific risks: (i) increased price sensitivity to changing interest rates and to a deteriorating economic environment; (ii) greater risk of loss due to default or declining credit quality; (iii) adverse company specific events more likely to render the issuer unable to make dividend, interest and/or principal payments; (iv) negative perception of the high-yield market which may depress the price and liquidity of high-yield securities; (v) volatility; and (vi) liquidity.

**Current Market Conditions Risk.** Current market conditions risk is the risk that a particular investment, or shares of the Fund in general, may fall in value due to current market conditions. As a means to fight inflation, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has begun to lower interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund's ability to achieve its investment strategies or make certain investments. Potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including high interest rates, declining valuations and elevated vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund's investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund's assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund's portfolio investments and could result in disruptions in the trading markets.

**Cyber Security Risk.** The Fund is susceptible to operational, information security and related risks through breaches in cyber security. A breach in cyber security refers to both intentional and unintentional events that may cause the Fund to lose proprietary information, suffer data corruption or lose operational capacity, any of which could result in a material adverse effect on the Fund or its

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

shareholders. Such events could cause the Fund to incur regulatory penalties, reputational damage, additional compliance costs associated with corrective measures and/or financial loss. Cyber security breaches may involve unauthorized access to the Fund's digital information systems through "hacking" or malicious software coding, but may also result from outside attacks such as denial-of-service attacks through efforts to make network services unavailable to intended users. Emerging threats like ransomware or zero-day exploits could also cause disruptions to Fund operations. In addition, cyber security breaches of the issuers of securities in which the Fund invests or the Fund's third-party service providers, such as its administrator, transfer agent, custodian, or Sub-Advisor, as applicable, among many other third-party service providers, can also subject the Fund to many of the same risks associated with direct cyber security breaches. Further, errors, misconduct, or compromise of accounts of employees of the Fund or its third-party service providers can also create material cybersecurity risks. Although the Fund has established risk management systems designed to reduce the risks associated with cyber security, there is no guarantee that such efforts will succeed, especially because the Fund does not directly control the cyber security systems of issuers or third party service providers. Cyber security incidents may also trigger Fund obligations under data privacy laws, potentially increasing notification and compliance burdens. Cyber security incidents affecting issuers in whose securities the Fund invests may also have a negative impact on the value of the securities of such issuers, and in turn, the value of the Fund.

**Europe Risk.** The Fund is subject to certain risks specifically associated with investments in the securities of European issuers. Political or economic disruptions in European countries, even in countries in which the Fund is not invested, may adversely affect security values and thus the Fund's holdings. A significant number of countries in Europe are member states in the European Union (the "EU"), and the member states no longer control their own monetary policies by directing independent interest rates for their currencies. In these member states, the authority to direct monetary policies, including money supply and official interest rates for the Euro, is exercised by the European Central Bank. In a 2016 referendum, the United Kingdom elected to withdraw from the EU ("Brexit"). After years of negotiations between the United Kingdom and the EU, a withdrawal agreement was reached whereby the United Kingdom formally left the EU. As the second largest economy among EU members, the implications of the United Kingdom's withdrawal are difficult to gauge and cannot be fully known. Its departure may negatively impact the EU and Europe as a whole by causing volatility within the EU, triggering prolonged economic downturns in certain European countries or sparking additional member states to contemplate departing the EU (thereby perpetuating political instability in the region).

**Illiquid and Restricted Securities Risk**. The Fund may invest in securities that are restricted and/or illiquid. Restricted securities are securities that cannot be offered for public resale unless registered under the applicable securities laws or that have a contractual restriction that prohibits or limits their resale. Restricted securities may be illiquid as they generally are not listed on an exchange and may have no active trading market. Investments in restricted securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase these securities. 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.

**Inflation Risk.** The Fund invests in securities that are subject to inflation risk. Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the present value of the Fund's assets and distributions may decline. This risk is more prevalent with respect to debt securities. Inflation rates may change frequently and drastically as a result of various factors, including unexpected shifts in the domestic or global economy, and the Fund's investments may not keep pace with inflation, which may result in losses to Fund investors.

**Interest Rate and Duration Risk**. Interest rate risk is the risk that securities will decline in value because of changes in market interest rates. For fixed rate securities, when market interest rates rise, the market value of such securities generally will fall. Investments in fixed rate securities with long-term maturities may experience significant price declines if long-term interest rates increase. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected prepayments. This may lock in a below-market yield, increase the security's duration and further reduce the value of the security. Fixed rate securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile 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. 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.

The interest rates payable on floating rate securities are not fixed and may fluctuate based upon changes in market rates. As short-term interest rates decline, interest payable on floating rate securities typically decreases. Alternatively, during periods of rising interest rates, interest payable on floating rate securities typically increases. Changes in interest rates on floating rate securities may lag behind

------

**Investment Objectives, Policies, Risks and Effects of Leverage (Continued)**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

changes in market rates or may have limits on the maximum increases in interest rates. The value of floating rate securities may decline if their interest rates do not rise as much, or as quickly, as interest rates in general.

**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. Leverage involves risks and special considerations for common shareholders including: (i) the likelihood of greater volatility of net asset value and market price of the common shares than a comparable portfolio without leverage; (ii) the risk that fluctuations in interest rates on borrowings will reduce the return to the common shareholders or will result in fluctuations in the dividends paid on the common shares; (iii) in a declining market, the use of leverage is likely to cause a greater decline in the net asset value of the common shares than if the Fund were not leveraged, which may result in a greater decline in the market price of the common shares; and (iv) when the Fund uses certain types of leverage, the investment advisory fee payable to the Advisor and by the Advisor to the Sub-Advisor will be higher than if the Fund did not use leverage.

**Management Risk and Reliance on Key Personnel**. The implementation of the Fund's investment strategy depends upon the continued contributions of certain key employees of the Advisor and Sub-Advisor, some of whom have unique talents and experience and would be difficult to replace. The loss or interruption of the services of a key member of the portfolio management team could have a negative impact on the Fund.

**Market Discount from Net Asset Value**. Shares of closed-end investment companies such as the Fund frequently trade at a discount from their net asset value. The Fund cannot predict whether its common shares will trade at, below or above net asset value.

**Market Risk.** Investments held by the Fund, as well as shares of the Fund itself, are subject to market fluctuations caused by real or perceived economic conditions, political events, regulatory factors or market developments, changes in interest rates and perceived trends in securities prices. Shares of the Fund could decline in value or underperform other investments as a result of the risk of loss associated with these market fluctuations. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of the Fund's shares, the liquidity of an investment, and result in increased market volatility. During any such events, the Fund's shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on the Fund's shares may widen and the returns on investment may fluctuate.

**Non-U.S. Securities Risk**. Investing in securities of non-U.S. issuers, which are generally denominated in non-U.S. currencies, 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. Foreign companies are generally not subject to the same accounting, auditing and financial reporting standards as are U.S. companies. In addition, there may be difficulty in obtaining or enforcing a court judgment abroad. These risks may be more pronounced to the extent that the Fund invests a significant amount of its assets in companies located in one region or in emerging markets.

**Operational Risk.** The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. These errors or failures may adversely affect the Fund's operations, including its ability to execute its investment process or calculate or disseminate its NAV in a timely manner. The Fund relies on third-parties for a range of services, including custody, valuation, and administration, among many others. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund's ability to meet its investment objective. Although the Fund and the Fund's investment advisor seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks.

**Potential Conflicts of Interest Risk**. First Trust, Stonebridge and the portfolio managers have interests which may conflict with the interests of the Fund. In particular, First Trust and Stonebridge currently manage and may in the future manage and/or advise other investment funds or accounts with the same or substantially similar investment objective and strategies as the Fund. In addition, while the Fund is using leverage, the amount of the fees paid to First Trust (and by First Trust to Stonebridge) for investment advisory and

------

**Investment Objectives, Policies, Risks and Effects of Leverage (Continued)**

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

management services are higher than if the Fund did not use leverage because the fees paid are calculated based on managed assets. Therefore, First Trust and Stonebridge have a financial incentive to leverage the Fund.

**Preferred/Hybrid Preferred and Debt Securities Risk**. An investment in preferred/hybrid preferred and debt securities is subject to certain risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Issuer Risk. The value of these securities may decline for a number of reasons which directly relate to the issuer, such as management performance, leverage and reduced demand for the issuer's goods and services. Additionally, an issuer may default on its obligation to make distributions or repay principal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Interest Rate Risk. Interest rate risk is the risk that fixed rate securities will decline in value because of changes in market interest rates. When market interest rates rise, the market value of fixed rate securities generally will fall. Market value generally falls further for fixed rate securities with longer duration. During periods of rising interest rates, the average life of certain types of securities may be extended because of slower than expected prepayments. This may lock in a below-market yield, increase the security's duration and further reduce the value of the security. Investments in fixed rate securities with long-term maturities may experience significant price declines if long-term interest rates increase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Floating Rate and Fixed-to-Floating Rate 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. Securities with a floating or variable interest rate component can be less sensitive to interest rate changes than securities with fixed interest rates. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Prepayment Risk. Prepayment risk is the risk that the issuer of a debt security will repay principal prior to the scheduled maturity date. During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the Fund to reinvest the proceeds from such prepayment in lower yielding securities, which may result in a decline in the Fund's income and distributions to common shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reinvestment Risk. Reinvestment risk is the risk that income from the Fund's portfolio will decline if the Fund invests the proceeds from matured, traded or called securities at market interest rates that are below the Fund portfolio's current earnings rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Subordination Risk. Preferred securities are typically subordinated to bonds and other debt instruments in a company's capital structure, in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt instruments.

In addition, preferred and hybrid preferred securities are subject to certain other risks, including deferral and omission risk, limited voting rights risk and special redemption rights risk.

**Reverse Repurchase Agreements Risk**. The Fund's use of reverse repurchase agreements may involve leverage risk. There is also the risk that the market value of the securities acquired with the proceeds of the reverse repurchase agreement may decline below the price of the securities that the Fund has sold but remains obligated to repurchase. In addition, there is a risk that the market value of the securities retained by the Fund may decline. Reverse repurchase agreements also involve the risk that the purchaser fails to return the securities as agreed upon, files for bankruptcy or becomes insolvent. The Fund may be restricted from taking normal portfolio actions during such time, could be subject to loss to the extent that the proceeds of the agreement are less than the value of securities subject to the agreement and may experience adverse tax consequences.

**Risks of Concentration in the Financials Sector**. Because the Fund invests 25% or more of its managed assets 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. The Fund may emphasize its investments in certain industries such as the banking and insurance industries and therefore may make the Fund more economically vulnerable in the event of a downturn in those industries. Financial companies are subject to extensive governmental regulation and intervention, which may adversely affect the scope of their activities, the prices they can charge, the amount and types of capital they must maintain and, potentially, their size. Governmental regulation may change frequently and may have significant adverse consequences for financial companies, including effects not intended by such regulation. The impact of more stringent capital requirements, or recent or future regulation in various countries, on any individual financial company or on financial companies as a whole cannot be predicted. Certain risks may impact the value of investments in financial companies more severely than those of investments in other issuers, including the risks associated with companies that operate with substantial financial leverage. Financial companies may also be adversely affected by volatility in interest rates, loan losses and other customer defaults, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Insurance companies in particular may be subject to severe price competition and/or rate regulation, which may have an adverse impact on their profitability. Financial companies are also a target for cyber attacks and may experience technology malfunctions and disruptions as a result.

**First Trust Intermediate Duration Preferred & Income Fund (FPF)**

**October 31, 2025 (Unaudited)**

**Smaller Companies Risk.** Small and/or mid capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies.

**Trust Preferred Securities Risk**. The risks associated with trust preferred securities typically include the financial condition of the financial institution that creates the trust, as the trust typically has no business operations other than holding the subordinated debt issued by the financial institution and issuing the trust preferred securities and common stock backed by the subordinated debt. If a financial institution is financially unsound and defaults on interest payments to the trust, the trust will not be able to make payments to holders of the trust preferred securities such as the Fund. The issuer of trust preferred securities is generally able to defer or skip payments for up to five years without being in default and certain enhanced trust preferred securities may have longer interest payment deferral periods.

**Valuation Risk**. Unlike publicly traded common stock which trades on national exchanges, there is no central place or exchange for certain preferred securities and debt securities trading. Preferred securities and debt securities generally trade on an "over-the- counter" market which may be anywhere in the world where the buyer and seller can settle on a price. Due to the lack of centralized information and trading, the valuation of certain preferred securities and debt securities may carry more risk than that of common stock. Uncertainties in the conditions of the financial market, unreliable reference data, lack of transparency and inconsistency of valuation models and processes may lead to inaccurate asset pricing.

**Effects of Leverage**

The aggregate principal amount of borrowings under the credit agreement (the "Credit Agreement") with The Bank of Nova Scotia represented 31.24% of the Managed Assets as of October 31, 2025. Asset coverage with respect to the borrowings under the Credit Agreement was 320.15% as of October 31, 2025, and the Fund had $21,525,000 of unutilized funds available for borrowing under the Credit Agreement as of that date. As of October 31, 2025, the maximum commitment amount under the Credit Agreement was $575,000,000. As of October 31, 2025, the approximate average annual interest and fee rate payable on such borrowings was 4.91%.

Assuming that the Fund's leverage costs remain as described above (at an assumed average annual cost of 4.91%), the annual return that the Fund's portfolio must experience (net of expenses) in order to cover its leverage costs would be 1.53%

The following table is furnished in response to requirements of the SEC. It is designed to illustrate the effect of leverage on Common Share total return, assuming investment portfolio total returns (comprised of income and changes in the value of securities held in the Fund's portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns experienced or expected to be experienced by the Fund.

The table further assumes leverage representing 31.24% of the Fund's Managed Assets, net of expenses, and an annual leverage interest and fee rate of 4.91%.

| Assumed Portfolio Total Return (Net of Expenses) | -10<br> %<br>| -5<br> %<br>| 0<br> %<br>| 5<br> %<br>| 10<br> %<br>|
| Common Share Total Return | -16.77<br> %<br>| -9.50<br> %<br>| -2.23<br> %<br>| 5.04<br> %<br>| 12.31<br> %<br>|

---

Common Share total return is composed of two elements: the Common Share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends or interest on its leverage) and gains or losses on the value of the securities the Fund owns. As required by SEC rules, the table above assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0% the Fund must assume that the distributions it receives on its investments are entirely offset by losses in the value of those securities.

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 advisor (not including a sub-advisor whose role is primarily portfolio management and is sub-contracted or overseen by another investment advisor) and any entity controlling, controlled by or under common control with the investment advisor 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 advisor (other than any sub-advisor whose role is primarily portfolio management and is sub-contracted with or overseen by another investment advisor) and any entity controlling, controlled by or under common control with the investment advisor 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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;(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 advisor (not including any sub-advisor whose role is primarily portfolio
management and is subcontracted with or overseen by another investment advisor), and any entity controlling, controlled by, or under common
control with the advisor that provides ongoing services to the Registrant for the fiscal year ended 2024 were $15,401 for the Registrant,

year ended 2025 were $15,142 for the Registrant, $28,620 for the Registrant's investment advisor and $9,180 for the Registrant's

management and is subcontracted with or overseen by another investment advisor), and any entity controlling, controlled by, or under common
control with the investment advisor 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.

#### SENIOR FINANCIAL OFFICER<br> CODE OF CONDUCT
I. Introduction

This code of conduct is being adopted by the investment companies advised by First Trust Advisors L.P., from time to time, (the "FUNDS"). The reputation and integrity of the Funds are valuable assets that are vital to the Funds' success. Each officer of the Funds, and officers and employees of the investment adviser to the Funds who work on Fund matters, including each of the Funds' senior financial officers ("SFOS"), is responsible for conducting each Fund's business in a manner that demonstrates a commitment to the highest standards of integrity. SFOs include the Principal Executive Officer (who is the President), the Controller (who is the principal accounting officer), and the Treasurer (who is the principal financial officer), and any person who performs a similar function.

The Funds, First Trust Advisors L.P. and First Trust Portfolios have adopted Codes of Ethics under Rule 17j-1 under the Investment Company Act of 1940 (the "RULE 17J-1 CODE"). These Codes of Ethics are designed to prevent certain conflicts of interest that may arise when officers, employees, or directors of the Funds and the foregoing entities know about present or future Fund transactions and/or have the power to influence those transactions, and engage in transactions with respect to those same securities in their personal account(s) or otherwise take advantage of their position and knowledge with respect to those securities. In an effort to prevent these conflicts and in accordance with Rule 17j-1, the Funds adopted their Rule 17j-1 Code to prohibit transactions and conduct that create conflicts of interest, and to establish compliance procedures.

The Sarbanes-Oxley Act of 2002 was designed to address corporate malfeasance and to help assure investors that the companies in which they invest are accurately and completely disclosing financial information. Under Section 406 of the Act, all public companies (including the Funds) must either have a code of ethics for their SFOs, or disclose why they do not. The Act was intended to prevent future situations (such as occurred in well-reported situations involving such companies as Enron and WorldCom) where a company creates an environment in which employees are afraid to express their opinions or to question unethical and potentially illegal business practices.

The Funds have chosen to adopt a senior financial officer Code of Conduct to encourage their SFOs, and other Fund officers and employees of First Trust Advisors or First Trust Portfolios to act ethically and to question potentially unethical or illegal practices, and to strive to ensure that the Funds' financial disclosures are complete, accurate, and understandable.

II. Purposes of This Code of Conduct

The purposes of this Code are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. To promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. To promote full, fair, accurate, timely, and understandable disclosure in reports and documents that the Funds file with, or submits to, the SEC and in other public communications the Funds make;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. To promote compliance with applicable governmental laws, rules and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. To encourage the prompt internal reporting to an appropriate person of violations of the Code; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. To establish accountability for adherence to the Code.

III. Questions About This Code

The Funds' Boards of Trustees have designated W. Scott Jardine or other appropriate officer designated by the President of the respective Funds to be the Compliance Coordinator for the implementation and administration of the Code.

IV. Handling of Financial Information

The Funds have adopted guidelines under which its SFOs perform their duties. However, the Funds expect that all officers or employees of the adviser or distributor who participate in the preparation of any part of any Fund's financial statements follow these guidelines with respect to each Fund:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Act with honesty and integrity and avoid violations of this Code, including actual or apparent conflicts of interest with the Fund in personal and professional relationships.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Disclose to the Fund's Compliance Coordinator any material transaction or relationship that reasonably could be expected to give rise to any violations of the Code, including actual or apparent conflicts of interest with the Fund. You should disclose these transactions or relationships whether you are involved or have only observed the transaction or relationship. If it is not possible to disclose the matter to the Compliance Coordinator, it should be disclosed to the Fund's Principal Financial Officer or Principal Executive Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Provide information to the Fund's other officers and appropriate employees of service providers (adviser, administrator, outside auditor, outside counsel, custodian, etc.) that is accurate, complete, objective, relevant, timely, and understandable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Endeavor to ensure full, fair, timely, accurate, and understandable disclosure in the Fund's periodic reports.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. Comply with the federal securities laws and other applicable laws and rules, such as the Internal Revenue Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. Act in good faith, responsibly, and with due care, competence and diligence, without misrepresenting material facts or allowing your independent judgment to be subordinated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. Respect the confidentiality of information acquired in the course of your work except when you have Fund approval to disclose it or where disclosure is otherwise legally mandated. You may not use confidential information acquired in the course of your work for personal advantage.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Share and maintain skills important and relevant to the Fund's needs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Proactively promote ethical behavior among peers in your work environment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;J. Responsibly use and control all assets and resources employed or entrusted to you.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;K. Record or participate in the recording of entries in the Fund's books and records that are accurate to the best of your knowledge.

V. Waivers of This Code

SFOs and other parties subject to this Code may request a waiver of a provision of this Code (or certain provisions of the Fund's Rule 17j-1 Code) by submitting their request in writing to the Compliance Coordinator for appropriate review. An executive officer of the Fund or the Audit Committee will decide whether to grant a waiver. All waivers of this Code must be disclosed to the Fund's shareholders to the extent required by SEC rules. A good faith interpretation of the provisions of this Code, however, shall not constitute a waiver.

VI. Annual Certification

Each SFO will be asked to certify on an annual basis that he/she is in full compliance with the Code and any related policy statements.

VII. Reporting Suspected Violations

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. SFOs or other officers of the Funds or employees of the First Trust group who work on Fund matters who observe, learn of, or, in good faith, suspect a violation of the Code MUST immediately report the violation to the Compliance Coordinator, another member of the Funds' or First Trust's senior management, or to the Audit Committee of the Fund Board. An example of a possible Code violation is the preparation and filing of financial disclosure that omits material facts, or that is accurate but is written in a way that obscures its meaning.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Because service providers such as an administrator, outside accounting firm, and custodian provide much of the work relating to the Funds' financial statements, you should be alert for actions by service providers that may be illegal, or that could be viewed as dishonest or unethical conduct. You should report these actions to the Compliance Coordinator even if you know, or think, that the service provider has its own code of ethics for its SFOs or employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. SFOs or other officers or employees who report violations or suspected violations in good faith will not be subject to retaliation of any kind. Reported violations will be investigated and addressed promptly and will be treated confidentially to the extent possible.

VIII. Violations of The Code

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Dishonest, unethical or illegal conduct will constitute a violation of this Code, regardless of whether this Code specifically refers to that particular conduct. A violation of this Code may result in disciplinary action, up to and including termination of employment. A variety of laws apply to the Funds and their operations, including the Securities Act of 1933, the Investment Company Act of 1940, state laws relating to duties owed by Fund directors and officers, and criminal laws. The federal securities laws generally prohibit the Funds from making material misstatements in its prospectus and other documents filed with the SEC, or from omitting to state a material fact. These material misstatements and omissions include financial statements that are misleading or omit materials facts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Examples of criminal violations of the law include stealing, embezzling, misapplying corporate or bank funds, making a payment for an expressed purpose on a Fund's behalf to an individual who intends to use it for a different purpose; or making payments, whether corporate or personal, of cash or other items of value that are intended to influence the judgment or actions of political candidates, government officials or businesses in connection with any of the Funds' activities. The Funds must and will report all suspected criminal violations to the appropriate authorities for possible prosecution, and will investigate, address and report, as appropriate, non-criminal violations.

**Stonebridge Advisors LLC**

**Proxy Voting Policy - Revised October 2025**

**General Policy**.

The preferred and hybrid securities in which we generally invest do not normally carry proxy voting rights, and we do not anticipate acquiring other equity securities that have such rights. But in the event that a proxy vote is solicited on a security held in client portfolios, our policy is to approach proxies in the manner that serves the best interests of our clients, as determined in our sole discretion. Accordingly, we may vote such proxies, abstain from voting (which generally requires submission of a proxy voting card), or affirmatively decide not to vote in accordance with the Proxy Voting Guidelines detailed below.

Clients may obtain a copy of Stonebridge's Proxy Voting Policy as well as information relating to how proxies were voted.

**Proxy Voting Guidelines.**

We will normally vote proxies in accordance with the following guidelines unless we determine that it is in the best interests of our clients do otherwise:

&nbsp;&nbsp;&nbsp;&nbsp;■ We will consider the proposal's expected impact on shareholder value and will not consider any benefit
to us, our employees or affiliates.

&nbsp;&nbsp;&nbsp;&nbsp;■ We consider the reputation, experience and competence of a company's management when we evaluate
the merits of investing in a particular company, and we invest in companies in which we believe management goals and shareholder goals
are aligned. Therefore, on most issues, we cast our votes in accordance with management's recommendations. However, when we believe
management's position on a particular issue is not in the best interests our clients, we will vote contrary to management's
recommendation.

&nbsp;&nbsp;&nbsp;&nbsp;■ With respect to a company's board of directors, we believe there should be a majority of independent
directors on company boards, and that audit, compensation and nominating committees should consist solely of independent directors. Therefore,
we will normally vote in favor of proposals that insure such independence.

&nbsp;&nbsp;&nbsp;&nbsp;■ With respect to auditors, we believe that the relationship between a public company and its auditors should
be limited primarily to the audit engagement, and we will normally vote in favor of proposals to prohibit or limit fees paid to auditors
for any services other than auditing or closely-related activities that do not raise any appearance of impaired independence.

&nbsp;&nbsp;&nbsp;&nbsp;■ With respect to equity-based compensation plans, we believe that appropriately designed plans approved
by a company's shareholders can be an effective way to align the interests of long-term shareholders and the interests of management,
employees and directors. However, we will normally vote against plans that substantially dilute our ownership interest in the company
or provide participants with excessive awards. We will also normally vote in favor of proposals to require the expensing of options.

&nbsp;&nbsp;&nbsp;&nbsp;■ With respect to shareholder rights, we believe that all shareholders of a company should have an equal
voice and that barriers that limit the ability of shareholders to effect corporate change and to realize the full value of their investment
are not desirable. Therefore, we will normally vote against proposals for supermajority voting rights, against the adoption of poison
pill plans, and against proposals for different classes of stock with different voting rights.

&nbsp;&nbsp;&nbsp;&nbsp;■ With respect to "social responsibility" issues, we believe that matters related to a company's
day-to-day business operations are primarily the responsibility of management. We are focused on maximizing long-term shareholder value
and will normally vote against shareholder proposals requesting that a company disclose or change certain business practices, unless we
believe the proposal would have a substantial, positive economic impact on the company.

&nbsp;&nbsp;&nbsp;&nbsp;■ We will abstain from voting (which generally requires submission of a proxy voting card) or affirmatively
decide not to vote if we determine that abstaining or not voting is in the best interests of the client or is immaterial to the client.
In making such a determination, we will consider various factors, including, but not limited to: (i) the costs associated with exercising
the proxy; (ii) any legal restrictions on trading resulting from the exercise of a proxy; and (iii) if we have only transitory possession
of the security for which the proxy is solicited.

&nbsp;&nbsp;&nbsp;&nbsp;■ Where a proxy vote solicitation is received for a security that was received in-kind and that does not
fit within any of Stonebridge's stated investment strategies and is slated for immediate sale without further analysis, we will
affirmatively decide not to vote such proxy because we do not have expertise on the security, and the proxy vote will have no impact on
the security while under the client's ownership.

**Responsibility**.

The Chief Compliance Officer ("CCO") or his/her designee is responsible for the administration of the proxy voting policy.

The Chief Investment Officer ("CIO") or his/her designee is responsible for voting and submitting proxies and monitoring corporate actions of portfolio securities.

**Implementation**.

Implementation procedures are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;■ A description of the Proxy Voting Policy is disclosed in Form ADV Part 2A, including the contact information
for Stonebridge. Clients who are interested in receiving a copy of the Proxy Voting Policy should reach out directly to Stonebridge using
the contact information provided in Form ADV Part 2A.

&nbsp;&nbsp;&nbsp;&nbsp;■ All existing clients may request, on an annual basis and at no charge, a copy of the Proxy Voting Policy.

&nbsp;&nbsp;&nbsp;&nbsp;■ When a proxy vote is required, the CIO or his designee will maintain documentation for a period of at
least five years of all proxies/corporate action information that was received, records of how and when the proxies were voted. When Stonebridge
deviates from this policy, or otherwise determines that not voting with management, or not voting at all (including abstaining from any
vote), is in the best interests of clients, Stonebridge will note the factors it considered for making for such determination in its records.

&nbsp;&nbsp;&nbsp;&nbsp;■ Client requests for information regarding proxy votes or policies and procedures shall be forwarded to
the CCO for a written response.

&nbsp;&nbsp;&nbsp;&nbsp;■ The CCO periodically reviews documentation maintained by the CIO to provide reasonable assurance that
procedures are followed and proxies are being voted in the best interest of the clients.
