(a)	This security 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. This security is not restricted on the foreign exchange where it trades freely without any additional registration. As such, it does not require the additional disclosure required of restricted securities.
(b)	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(c)	This security is fair valued by the Advisor’s Pricing Committee in accordance with procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the Investment Company Act of 1940 and rules thereunder, as amended. At January 31, 2023, securities noted as such are valued at $907,503 or 2.6% of net assets. Certain of these securities are fair valued using a factor provided by a third-party pricing service due to the change in value between the foreign markets’ close and the New York Stock Exchange (“NYSE”) close exceeding a certain threshold. On days when this threshold is not exceeded, these securities are typically valued at the last sale price on the exchange on which they are principally traded.
(d)	Non-income producing security.
(e)	This security is taxed as a “C” corporation for federal income tax purposes.

Valuation Inputs

The Funds are 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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that 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.

First Trust Senior Loan Fund (FTSL)

Portfolio of Investments (Continued)

January 31, 2023 (Unaudited)

(a)	Senior Floating-Rate Loan Interests (“Senior Loans”) in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the LIBOR, (ii) the SOFR obtained from the U.S. Department of the Treasury’s Office of Financial Research, (iii) the prime rate offered by one or more United States banks or (iv) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR or SOFR floor that establishes a minimum LIBOR or SOFR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical LIBOR or SOFR period, spread and floor, but different LIBOR or SOFR reset dates.
(b)	Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown.
(c)	On June 16, 2022, Mallinckrodt plc completed a Bankruptcy Plan of Reorganization. In connection with the Plan of Reorganization, the Fund received a new replacement term loan.
(d)	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.

Valuation Inputs

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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

	Total Value at 1/31/2023			Level 1 Quoted Prices		Level 2 Significant Observable Inputs		Level 3 Significant Unobservable Inputs

(a)	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. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P. (“First Trust” or the “Advisor”). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At January 31, 2023, securities noted as such amounted to $1,104,921,875 or 70.3% of net assets.
(b)	This security or a portion of this security is segregated as collateral for borrowings. At January 31, 2023, the segregated value of these securities amounts to $569,077,400.
(c)	Senior Floating-Rate Loan Interests (“Senior Loans”) in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the LIBOR, (ii) the SOFR obtained from the U.S. Department of the Treasury’s Office of Financial Research, (iii) the prime rate offered by one or more United States banks or (iv) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR or SOFR floor that establishes a minimum LIBOR or SOFR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical LIBOR or SOFR period, spread and floor, but different LIBOR or SOFR reset dates.
(d)	Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown.
(e)	Non-income producing security.
(f)	Security received in a transaction exempt from registration under the 1933 Act. The security may be resold pursuant to an exemption from registration under the 1933 Act, typically to qualified institutional buyers (see Restricted Securities table).
(g)	Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be illiquid by the Advisor.
(h)	This issuer has filed for protection in bankruptcy court.
(i)	Rate shown reflects yield as of January 31, 2023.

Valuation Inputs

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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

(a)	Floating or variable rate security.
(b)	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. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P., the Fund’s advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At January 31, 2023, securities noted as such amounted to $483,981,115 or 6.1% of net assets.
(c)	Fixed-to-floating or fixed-to-variable rate security. The interest rate shown reflects the fixed rate in effect at January 31, 2023. At a predetermined date, the fixed rate will change to a floating rate or a variable rate.
(d)	When-issued security. The interest rate shown reflects the rate in effect at January 31, 2023. Interest will begin accruing on the security’s first settlement date.
(e)	Step-up security. A security where the coupon increases or steps up at a predetermined date.
(f)	Collateral Strip Rate security. Coupon is based on the weighted net interest rate of the investment’s underlying collateral. The interest rate resets periodically.

Valuation Inputs

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: 

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

Valuation Inputs

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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations
 based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the
 assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

Valuation Inputs

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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations
based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

Valuation Inputs

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:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:

(a)	Fixed-to-floating or fixed-to-variable rate security. The interest rate shown reflects the fixed rate in effect at January 31, 2023. At a predetermined date, the fixed rate will change to a floating rate or a variable rate.
(b)	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, and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by First Trust Advisors L.P., the Fund’s advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At January 31, 2023, securities noted as such amounted to $11,875,347 or 3.0% of net assets.
(c)	Senior Floating-Rate Loan Interests (“Senior Loans”) in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the LIBOR, (ii) the SOFR obtained from the U.S. Department of the Treasury’s Office of Financial Research, (iii) the prime rate offered by one or more United States banks or (iv) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR or SOFR floor that establishes a minimum LIBOR or SOFR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical LIBOR or SOFR period, spread and floor, but different LIBOR or SOFR reset dates.
(d)	Senior Loans generally are subject to mandatory and/or optional prepayment. As a result, the actual remaining maturity of Senior Loans may be substantially less than the stated maturities shown.
(e)	Rate shown reflects yield as of January 31, 2023.

Valuation Inputs

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:  

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.

A summary of the inputs used to value the Fund’s investments as of January 31, 2023 is as follows:
