(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

(b)
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.

(a)
Variable rate demand bond. Interest rate is reset periodically by the agent based on current market conditions.
(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 April 30, 2026, securities noted as such amounted to $6,765,981 or 3.0% of net assets.
(c)
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.

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.
