(a)	Portfolio securities are categorized based upon their country of incorporation, which can be different from the country categorization of the Fund’s underlying index. For a breakdown of the portfolio securities by sector, please see the Sector Allocation table.
(b)	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 June 30, 2023, securities noted as such are valued at $118,408,264 or 60.7% 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 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.
(c)	Non-income producing security.

(d)	All or a portion of this security is on loan for securities lending. The remaining contractual maturity of all of the securities lending transactions is overnight and continuous. The aggregate value of such securities, including those sold and pending settlement, is $498,420 and the total value of the collateral held by the Fund is $497,000. On June 30, 2023, the last business day of the period, there was sufficient collateral based on the end of day market value from the prior business day; however, as a result of market movement from June 29 to June 30, the value of the related securities loaned was above the collateral value received.
(e)	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.
(f)	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(g)	Rate shown reflects yield as of June 30, 2023.

First Trust Exchange-Traded Fund II
Additional Information
June 30, 2023 (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.
