On July 19, 2019, Cboe BZX Exchange, Inc. (“Exchange” or “BZX”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”)

II. Summary of the Proposed Rule Change, as Modified by Amendment No. 1 
BZX Rule 14.11(i) permits the Exchange to generically list Managed Fund Shares 
issued by a fund whose portfolio components satisfy certain criteria. The Exchange must file separate proposals under Section 19(b) of the Act to list and trade shares of a series of Managed Fund Shares with portfolio components that do not satisfy the applicable generic listing criteria (including portfolio components not specified in the generic listing standards).
According to the Exchange, the Fund will satisfy all of the applicable generic listing requirements except for BZX Rule 14.11(i)(4)(C)(ii)(a),
which requires that fixed income securities in a fund's portfolio that in the aggregate account for at least 75% of the fixed income weight of the portfolio each have a minimum principal amount outstanding of $100 million or more. Accordingly, the Exchange filed the pending proposal to seek Commission approval to list and trade the Shares.
BlackRock Fund Advisors (“Adviser”) is the investment adviser to the Fund.
The Fund will seek to maximize tax-free current income from a portfolio composed of short maturity, investment-grade municipal bonds issued in the State of California. To achieve its objective, the Fund will invest, under Normal Market Conditions,
at least 80% of its net assets in U.S.-dollar denominated investment-grade short-term fixed- and floating-rate Municipal Securities, as defined below, with remaining maturities of five years or less, issued in the State of California by or on behalf of California state or local governments or agencies, whose interest payments are exempt from U.S. federal, including the federal alternative minimum tax, and California state income taxes. Under Normal Market Conditions, the Fund will seek to maintain a weighted average maturity that is less than three years.
Municipal Securities include only the following instruments: General obligation bonds; limited obligation bonds (or revenue bonds); municipal notes; municipal commercial paper; tender option bonds; variable rate demand notes and demand obligations; municipal lease obligations, stripped securities; structured securities; 
zero coupon securities; and shares of exchange-traded and non-exchange-traded investment companies that principally invest in such Municipal Securities.
Other Portfolio Holdings. The Fund may also, to a limited extent (under Normal Market Conditions, less than 20% of the Fund's net assets), invest in certain futures, options and swap contracts; 
cash and cash equivalents; as well as in Municipal Securities of issuers located outside of California whose interest payments are exempt from regular federal income taxes.
The Fund may also enter into repurchase and reverse repurchase agreements for Municipal Securities (collectively, “Repurchase Agreements”). The Fund may also invest in short-term instruments (“Short-Term Instruments”),
which includes exchange traded and non-exchange traded investment companies that invest in money market instruments.
Investment Restrictions. The Fund may hold up to an aggregate amount of 15% of its net assets in illiquid assets (calculated at the time of investment), as deemed illiquid by the Adviser under the 1940 Act. The Fund will monitor its portfolio liquidity on an ongoing basis to determine whether, in light of current circumstances, an adequate level of liquidity is being maintained, and will consider taking appropriate steps in order to maintain adequate liquidity if, through a change in values, net assets, or other circumstances, more than 15% of the Fund's net assets are held in illiquid assets.
Additionally, the Exchange states that the Fund will launch with at least 300,000 Shares outstanding. The Exchange also states: (1) The portfolio will hold a minimum of 15 different Municipal Securities from at least 15 unique issuers when at least six creation units are outstanding, but will never hold fewer than 10 different Municipal Start Printed Page 59671Securities from at least 10 unique issuers; (2) no single obligor will account for more than 10% of the weight of the Fund's portfolio and no 10 obligors will account for more than 75% of the weight of the Fund's portfolio.
Additionally, no more than 50% of the Fund's assets will be invested in issuers that are more than 5% of the value of the Fund's assets, and the Fund will not invest more than 25% of its assets in any single issuer.
III. Proceedings To Determine Whether To Approve or Disapprove SR-CboeBZX-2019-068 and Grounds for Disapproval Under Consideration
The Commission is instituting proceedings pursuant to Section 19(b)(2)(B) of the Act 
to determine whether the proposed rule change, as modified by Amendment No. 1, should be approved or disapproved. Institution of such proceedings is appropriate at this time in view of the legal and policy issues raised by the proposal. Institution of proceedings does not indicate that the Commission has reached any conclusions with respect to any of the issues involved. Rather, as described below, the Commission seeks and encourages interested persons to provide comments on the proposal.
Pursuant to Section 19(b)(2)(B) of the Act,
the Commission is providing notice of the grounds for disapproval under consideration. The Commission is instituting proceedings to allow for additional analysis of the proposal's consistency with Section 6(b)(5) of the Act, which requires, among other things, that the rules of a national securities exchange be “designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade,” and “to protect investors and the public interest.” 
Specifically, the Commission seeks comment regarding the following:
1. Would the proposed requirement that the portfolio hold a minimum of ten different Municipal Securities from at least ten unique issuers or, when at least six creation units are outstanding, fifteen different Municipal Securities from at least fifteen unique issuers be sufficient to ensure that the Fund's portfolio isn't susceptible to manipulation?
2. Would the proposed concentration limit, i.e., that no single obligor will account for more than 10% of the weight of the Fund's portfolio and no ten obligors will account for more than 75% of the weight of the Fund's portfolio, be sufficient to ensure that the Fund's portfolio isn't susceptible to manipulation?
3. Taken collectively, would the proposed listing requirements adequately ensure that the Fund's portfolio would not be susceptible to manipulation?
IV. Procedure: Request for Written Comments
The Commission requests that interested persons provide written submissions of their views, data, and arguments with respect to the issues identified above, as well as any other concerns they may have with the proposal. In particular, the Commission invites the written views of interested persons concerning whether the proposed rule change, as modified by Amendment No. 1, is consistent with Section 6(b)(5) or any other provision of the Act, or the rules and regulations thereunder. Although there do not appear to be any issues relevant to approval or disapproval that would be facilitated by an oral presentation of views, data, and arguments, the Commission will consider, pursuant to Rule 19b-4 under the Act,
any request for an opportunity to make an oral presentation.
Interested persons are invited to submit written data, views, and arguments regarding whether the proposed rule change, as modified by Amendment No. 1, should be approved or disapproved by November 26, 2019. Any person who wishes to file a rebuttal to any other person's submission must file that rebuttal by December 10, 2019. The Commission asks that commenters address the sufficiency of the Exchange's statements in support of the proposal, which are set forth in Amendment No. 1,
in addition to any other comments they may wish to submit about the proposal.
In this regard, the Commission seeks comment on the Exchange's proposed generic listing standards for Shares based on an index or portfolio of Municipal Securities. The Commission specifically seeks comment on whether the proposed requirement that an underlying index or portfolio must include a minimum of 500 component Municipal Securities is consistent with the requirement that the rules of a national securities exchange be “designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade,” and “to protect investors and the public interest.”
