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

&nbsp;&nbsp;&nbsp;&nbsp;(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 "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 April 30, 2025, securities noted as such amounted to $264,562,361
 or 28.0% of net assets.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Inverse floating rate security.

&nbsp;&nbsp;&nbsp;&nbsp;(d) 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 April 30, 2025, securities noted as such are valued at $4,130,500 or 0.4% of net assets.

&nbsp;&nbsp;&nbsp;&nbsp;(e) When-issued security. The interest rate shown reflects the rate in effect at April
 30, 2025. Interest will begin accruing on the security's first settlement date.

&nbsp;&nbsp;&nbsp;&nbsp;(f) Weighted Average Coupon security. Coupon is based on the blended interest rate of
 the underlying holdings, which may have different coupons. The coupon may change in any period.

&nbsp;&nbsp;&nbsp;&nbsp;(g) Collateral Strip Rate security. Coupon is based on the weighted net interest rate of the investment's underlying collateral. The interest rate resets periodically.

&nbsp;&nbsp;&nbsp;&nbsp;(h) All or a portion of this security is part of a mortgage dollar roll agreement.

&nbsp;&nbsp;&nbsp;&nbsp;(i) Fixed-to-floating or fixed-to-variable rate security. The interest rate shown reflects
 the fixed rate in effect at April 30, 2025. At a predetermined date, the fixed rate will change to a floating rate or a variable rate.

&nbsp;&nbsp;&nbsp;&nbsp;(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, 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 April 30, 2025, securities noted as such amounted to $4,590,544
 or 44.9% of net assets.

&nbsp;&nbsp;&nbsp;&nbsp;(b) Collateral Strip Rate security. Coupon is based on the weighted net interest rate of the investment's underlying collateral. The interest rate resets periodically.

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

&nbsp;&nbsp;&nbsp;&nbsp;(d) Weighted Average Coupon security. Coupon is based on the blended interest rate of
 the underlying holdings, which may have different coupons. The coupon may change in any period.

&nbsp;&nbsp;&nbsp;&nbsp;(e) Rate shown reflects yield as of April 30, 2025.

 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 "Advisor"). Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific

 or 74.9% of net assets.

&nbsp;&nbsp;&nbsp;&nbsp;(b) Collateral Strip Rate security. Coupon is based on the weighted net interest rate of the investment's underlying collateral. The interest rate resets periodically.

&nbsp;&nbsp;&nbsp;&nbsp;(c) Step-up security. A security where the coupon increases or steps up at a predetermined
 date.

&nbsp;&nbsp;&nbsp;&nbsp;(d) 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 April 30, 2025, securities noted as such are valued at $254,999 or 2.5% of net assets.

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

&nbsp;&nbsp;&nbsp;&nbsp;(f) Weighted Average Coupon security. Coupon is based on the blended interest rate of
 the underlying holdings, which may have different coupons. The coupon may change in any period.

&nbsp;&nbsp;&nbsp;&nbsp;(g) Rate shown reflects yield as of April 30, 2025.

**Additional Information**

**April 30, 2025 (Unaudited)**

**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:

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

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

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