Additional Information

 

First Trust Exchange-Traded Fund VIII

May 31, 2021 (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:

•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.

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.

(a) All or a portion of this security is part of a mortgage dollar roll agreement.
(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 May 31, 2021, securities noted as such amounted to $752,006,426 or 14.7% of net assets.
(c) Floating or variable rate security.
(d) Fixed-to-floating security. The interest rate shown reflects the fixed rate in effect at May 31, 2021. At a predetermined date, the fixed rate will change to a floating rate.
(e) Collateral Strip Rate security. Coupon is based on the weighted net interest rate of the investment’s underlying collateral. The interest rate resets periodically.
(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.
(g) Step-up security. A security where the coupon increases or steps up at a predetermined date.
(h) When-issued security. The interest rate shown reflects the rate in effect at May 31, 2021. Interest will begin accruing on the security’s first settlement date.
(i) This security is fair valued by the Advisor’s Pricing Committee in accordance with procedures adopted by the Trust’s Board of Trustees, and in accordance with provisions of the Investment Company Act of 1940, as amended. At May 31, 2021, securities noted as such are valued at $13,809,905 or 0.3% of net assets.

(j) This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(k) This issuer is in default and interest is not being accrued by the Fund nor paid by the issuer.
(l) 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 prime rate offered by one or more United States banks or (iii) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR floor that establishes a minimum LIBOR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical LIBOR period, spread and floor, but different LIBOR reset.
(m) 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.
(n)

The issuer will pay interest on the loans in cash and in Payment-In-Kind (“PIK”) interest. Interest paid in cash will accrue at the rate of 7.00% per annum (“Cash Interest Rate”) and PIK interest will accrue on the loan at the rate of 8.25% per annum. For the fiscal year-to-date period (September 1, 2020 to May 31, 2021), the Fund received a portion of the

interest in cash and PIK interest with a principal value of $75,641 for Cineworld Group PLC.

(o) Zero coupon security.
(p) Rate shown reflects yield as of May 31, 2021.

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 (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.

Additional Information

 

First Trust Exchange-Traded Fund VIII

May 31, 2021 (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:

•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.

Additional Information

 

First Trust Exchange-Traded Fund VIII

May 31, 2021 (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:

•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.

Additional Information

 

First Trust Exchange-Traded Fund VIII

May 31, 2021 (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:

•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.

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.
