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, 2026, securities noted as such amounted to $805,420,229 or 34.0% of net assets.

Weighted Average Coupon security. Coupon is based on the blended interest rate of the underlying holdings, which may have

predetermined date, the fixed rate will change to a floating rate or a variable rate.

(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 “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, 2026, securities noted as such amounted to $15,782,757 or 48.5% of net assets.
(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.
(c)
Floating or variable rate security.
(d)
When-issued security. The interest rate shown reflects the rate in effect at April 30, 2026. Interest will begin accruing on the
security’s first settlement date.
(e)
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.
(f)
Zero coupon security.
(g)
Rate shown reflects yield as of April 30, 2026.

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.
