I. Introduction

On May 11, 2016, NYSE Arca, Inc. (“Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] a proposed rule change to permit the Fidelity Corporate Bond ETF, Fidelity Investment Grade Bond ETF, Fidelity Limited Term Bond ETF, and Fidelity Total Bond ETF (individually, “Fund,” and collectively, “Funds”) to consider securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Securities Act”) as debt securities eligible for principal investment. The proposed rule change was published for comment in the Federal Register on May 31, 2016.^[3] On June 30, 2016, pursuant to section 19(b)(2) of the Act,^[4] the Commission designated a longer period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change.^[5] On July 26, 2016, the Exchange filed Amendment No. 1 to the proposed rule change.^[6] The Commission Start Printed Page 60760has received no comments on the proposed rule change. This order institutes proceedings under section 19(b)(2)(B) of the Act^[7] to determine whether to approve or disapprove the proposed rule change, as modified by Amendment No. 1 thereto.

II. Exchange's Description of the Proposal

The Commission approved the listing and trading of shares (“Shares”) of the Funds under NYSE Arca Equities Rule 8.600,^[8] which governs the listing and trading of Managed Fund Shares. The Exchange proposes to amend the representation in the Prior Corporate Bond Notice and Prior Total Bond Notice to provide that each Fund may include Rule 144A securities within a Fund's principal investments in debt securities (i.e., debt securities in which at least 80% of a Fund's assets are invested).

A. Exchange's Description of the Funds

Fidelity Investments Money Management, Inc. (“FIMM”), an affiliate of Fidelity Management & Research Company (“FMR”), is the manager (“Manager”) of each Fund. FMR Co., Inc. (“FMRC”) serves as a sub-adviser for the Fidelity Total Bond ETF. FMRC has day-to-day responsibility for choosing certain types of investments of foreign and domestic issuers for Fidelity Total Bond ETF. Other investment advisers, which also are affiliates of FMR, serve as sub-advisers to the Funds and assist FIMM with foreign investments, including Fidelity Management & Research (U.K.) Inc., Fidelity Management & Research (Hong Kong) Limited, and Fidelity Management & Research (Japan) Inc. (individually, “Sub-Adviser,” and together with FMRC, collectively “Sub-Advisers”). Fidelity Distributors Corporation is the distributor for the Funds' Shares.

The Funds are funds of Fidelity Merrimack Street Trust (“Trust”), a Massachusetts business trust.^[9] The Exchange represents that the Shares of the Fidelity Corporate Bond ETF, Fidelity Limited Term Bond ETF, and Fidelity Total Bond ETF are currently trading on the Exchange.

1. Fidelity Corporate Bond ETF

As described in the Prior Corporate Bond Notice, the Fidelity Corporate Bond ETF seeks a high level of current income. The Manager normally invests at least 80% of Fidelity Corporate Bond ETF assets in investment-grade corporate bonds and other corporate debt securities.^[10] Corporate debt securities are bonds and other debt securities issued by corporations and other business structures, as described in the Prior Corporate Bond Notice.

The Fidelity Corporate Bond ETF may hold uninvested cash or may invest it in cash equivalents such as money market securities, or shares of short-term bond exchanged-traded funds registered under the 1940 Act (“ETFs”), or mutual funds or money market funds, including Fidelity central funds (special types of investment vehicles created by Fidelity for use by the Fidelity funds and other advisory clients). The Manager uses the Barclays U.S. Credit Bond Index as a guide in structuring the Fund and selecting its investments. FIMM manages the Fund to have similar overall interest rate risk to the Barclays U.S. Credit Bond Index.

As stated in the Prior Corporate Bond Releases, in buying and selling securities for the Fund, the Manager analyzes the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the Fund's exposure to various risks, including interest rate risk, the Manager considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the Fund's competitive universe and internal views of potential future market conditions.

While the Manager normally invests at least 80% of assets of the Fund in investment grade corporate bonds and other corporate debt securities, as described above, the Manager may invest up to 20% of the Fund's assets in other securities and financial instruments, as summarized below.

In addition to corporate debt securities, the debt securities in which the Fund may invest are U.S. Government securities; repurchase agreements and reverse repurchase agreements; mortgage- and other asset-backed securities; loans; loan participations, loan assignments, and other evidences of indebtedness, including letters of credit, revolving credit facilities, and other standby financing commitments; structured securities; stripped securities; municipal securities; sovereign debt obligations; obligations of international agencies or supranational entities; and other securities believed to have debt-like characteristics, including hybrid securities, which may offer characteristics similar to those of a bond security such as stated maturity and preference over equity in bankruptcy.

The Fund may invest in restricted securities, which are subject to legal restrictions on their sale. Restricted securities generally can be sold in privately negotiated transactions, pursuant to an exemption from registration under the Securities Act, or in a registered public offering.

2. Fidelity Investment Grade Bond ETF

As described in the Prior Total Bond Notice, the Fidelity Investment Grade Bond ETF (which has not yet commenced operation) will seek a high level of current income. The Manager normally will invest at least 80% of the Start Printed Page 60761Fund's assets in investment-grade debt securities (those of medium and high quality). The debt securities in which the Fund may invest are corporate debt securities; U.S. Government securities; repurchase agreements and reverse repurchase agreements; money market securities; mortgage- and other asset-backed securities; senior loans; loan participations and loan assignments and other evidences of indebtedness, including letters of credit, revolving credit facilities and other standby financing commitments; stripped securities; municipal securities; sovereign debt obligations; and obligations of international agencies or supranational entities (collectively, “Debt Securities”).

As described in the Prior Total Bond Notice, the Fidelity Investment Grade Bond ETF may hold uninvested cash or may invest it in cash equivalents such as repurchase agreements, shares of short term bond ETFs, mutual funds, or money market funds, including Fidelity central funds (special types of investment vehicles created by Fidelity for use by the Fidelity funds and other advisory clients). The Manager will use the Barclays U.S. Aggregate Bond Index (“Aggregate Index”) as a guide in structuring the Fund and selecting its investments, and will manage the Fund to have similar overall interest rate risk to the Aggregate Index.

As described in the Prior Total Bond Notice, the Manager will consider other factors when selecting the Fidelity Investment Grade Bond ETF's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the Fidelity Investment Grade Bond ETF's exposure to various risks, including interest rate risk, the Manager will consider, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the Fidelity Investment Grade Bond ETF's competitive universe, and internal views of potential future market conditions.

3. Fidelity Limited Term Bond ETF

As described in the Prior Total Bond Notice, the Fidelity Limited Term Bond ETF seeks to provide a high rate of income. The Manager normally invests at least 80% of the Fidelity Limited Term Bond ETF's assets in investment-grade Debt Securities (those of medium and high quality).

The Fidelity Limited Term Bond ETF may hold uninvested cash or may invest it in cash equivalents such as repurchase agreements, shares of short term bond ETFs, mutual funds, or money market funds, including Fidelity central funds (special types of investment vehicles created by Fidelity for use by the Fidelity funds and other advisory clients). The Manager uses the Fidelity Limited Term Composite Index (“Composite Index”) as a guide in structuring the Fund and selecting its investments. The Manager manages the Fidelity Limited Term Bond ETF to have similar overall interest rate risk to the Composite Index.

The Manager considers other factors when selecting the Fidelity Limited Term Bond ETF's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the Fidelity Limited Term Bond ETF's exposure to various risks, including interest rate risk, the Manager considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the Fund's competitive universe, and internal views of potential future market conditions.

4. Fidelity Total Bond ETF

As described in the Prior Total Bond Notice, the Fidelity Total Bond ETF seeks a high level of current income. The Manager normally invests at least 80% of the Fidelity Total Bond ETF's assets in Debt Securities. The Manager allocates the Fidelity Total Bond ETF's assets across investment-grade, high yield, and emerging market Debt Securities. The Manager may invest up to 20% of the Fund's assets in lower-quality Debt Securities.

The Fidelity Total Bond ETF may hold uninvested cash or may invest it in cash equivalents such as repurchase agreements, shares of short term bond ETFs, mutual funds, or money market funds, including Fidelity central funds (special types of investment vehicles created by Fidelity for use by the Fidelity funds and other advisory clients).

The Manager uses the Barclays U.S. Universal Bond Index (“Universal Index”) as a guide in structuring and selecting the investments of the Fidelity Total Bond ETF and selecting its investments, and in allocating the Fidelity Total Bond ETF's assets across the investment-grade, high yield, and emerging market asset classes. The Manager manages the Fidelity Total Bond ETF to have similar overall interest rate risk to the Universal Index. The Manager considers other factors when selecting the Fund's investments, including the credit quality of the issuer, security-specific features, current valuation relative to alternatives in the market, short-term trading opportunities resulting from market inefficiencies, and potential future valuation. In managing the Fund's exposure to various risks, including interest rate risk, the Manager considers, among other things, the market's overall risk characteristics, the market's current pricing of those risks, information on the Fund's competitive universe, and internal views of potential future market conditions.

As described in the Prior Total Bond Notice, the Manager may invest the Fidelity Total Bond ETF's assets in Debt Securities of foreign issuers in addition to securities of domestic issuers.

5. Other Investments of the Funds

While, as described above, the Manager normally invests at least 80% of assets of Fidelity Limited Term Bond ETF in investment-grade Debt Securities (and will normally invest at least 80% of assets of the Fidelity Investment Grade Bond ETF in investment-grade Debt Securities), and the Manager normally invests at least 80% of assets of the Fidelity Total Bond ETF in Debt Securities, the Manager may invest up to 20% of a Fund's assets in other securities and financial instruments (“Other Investments,” as described in the Prior Total Bond Notice). As described in the Prior Corporate Bond Notice and Prior Total Bond Notice, as part of a Fund's Other Investments, (i.e., up to 20% of a Fund's assets), each Fund may invest in restricted securities, which are subject to legal restrictions on their sale.^[11]

B. Exchange's Description of the Proposed Change to the Principal Investments of the Funds

The Exchange proposes that each Fund may include Rule 144A securities within a Fund's principal investments in debt securities (i.e., debt securities in which at least 80% of a Fund's assets are invested). As discussed below, the Exchange believes it is appropriate for Rule 144A securities to be included as Start Printed Page 60762principal investments of a Fund in view of (1) the high level of liquidity in the market for such securities compared to other debt securities asset classes, and (2) the high level of transparency in the market for Rule 144A securities, particularly in light of reporting of transaction data in such securities through the Trade Reporting and Compliance Engine (“TRACE”) operated by the Financial Industry Regulatory Authority (“FINRA”). All of the Rule 144A securities in which a Fund invests will be corporate debt securities for which transactions are reported in TRACE.

FMR has represented to the Exchange that Rule 144A securities account for approximately 20% of daily trading volume in U.S. corporate bonds. Dealers trade and report transactions in Rule 144A securities in the same manner as registered corporate bonds. While the average number of daily trades and U.S. dollar volume in registered corporate bonds is much higher than in Rule 144A securities, the average lot size is higher for Rule 144A securities.^[12] Specifically, the average lot size for 144A securities for the period January 1, 2015 through August 31, 2015 was approximately $2.2 million, compared to an average lot size for the same period of approximately $500,000 for registered corporate bonds.

In addition, in 2013, the Commission approved FINRA rules relating to dissemination of information regarding transactions in Rule 144A securities in TRACE.^[13] In approving FINRA's proposed rule change to amend its rules regarding dissemination of Rule 144A transactions, the Commission stated:

Real-time dissemination of last-sale information could aid dealers in deriving better quotations, because they would know the prices at which other market participants had recently transacted in the same or similar instruments. This information could aid all market participants in evaluating current quotations, because they could inquire why dealer quotations might differ from the prices of recently executed transactions. Furthermore, post-trade transparency affords market participants a means of testing whether dealer quotations before the last sale were close to the price at which the last sale was executed. In this manner, post-trade transparency can promote price competition between dealers and more efficient price discovery and ultimately lower transaction costs in the market for Rule 144A securities.

Transactions executed by FINRA members became subject to dissemination through FINRA's TRACE on June 30, 2014, thus providing a level of transparency to the Rule 144A market comparable to that of registered bonds.^[14]

The Exchange notes that, while the proposed rule change would categorize Rule 144A securities within a Fund's principal investments in debt securities, any investments in Rule 144A securities, of course, would be required to comply with restrictions under the 1940 Act and rules thereunder relating to investment in illiquid assets. As stated in the Prior Corporate Bond Notice and Prior Total Bond Notice, each Fund may hold up to an aggregate amount of 15% of its net assets in illiquid assets (calculated at the time of investment), including Rule 144A securities deemed illiquid by the Manager or Sub-Advisers. Each Fund monitors 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 a Fund's net assets are held in illiquid assets. Illiquid assets include assets subject to contractual or other restrictions on resale and other instruments that lack readily available markets as determined in accordance with Commission staff guidance.^[15]

Moreover, as stated in the Prior Corporate Bond Notice and Prior Total Bond Notice, each Fund does not currently intend to purchase any asset if, as a result, more than 10% of its net assets would be invested in assets that are deemed to be illiquid because they are subject to legal or contractual restrictions on resale or because they cannot be sold or disposed of in the ordinary course of business at approximately the prices at which they are valued. For purposes of a Fund's illiquid assets limitation discussed above, if through a change in values, net assets, or other circumstances, a Fund were in a position where more than 10% of its net assets were invested in illiquid assets, it would consider appropriate steps to protect liquidity.

The Prior Corporate Bond Notice and Prior Total Bond Notice stated that various factors may be considered in determining the liquidity of a Fund's investments, including: (1) The frequency of trades and quotes for the asset; (2) the number of dealers wishing to purchase or sell the asset and the number of other potential purchasers; (3) dealer undertakings to make a market in the asset; and (4) the nature Start Printed Page 60763of the asset and the nature of the marketplace in which it trades (including any demand, put or tender features, the mechanics and other requirements for transfer, any letters of credit or other credit enhancement features, any ratings, the number of holders, the method of soliciting offers, the time required to dispose of the security, and the ability to assign or offset the rights and obligations of the asset).

The Exchange believes that the size of the Rule 144A market (approximately 20% of daily trading volume in U.S. corporate bonds), the active participation of multiple dealers utilizing trading protocols that are similar to those in the corporate bond market, and the transparency of the 144A market resulting from reporting of Rule 144A transactions in TRACE will deter manipulation in trading the Shares. The Exchange notes that all of the Rule 144A securities in which a Fund invests will be corporate debt securities for which transactions are reported in TRACE.

The Exchange represents that, except for the change described above, all other representations made in the Prior Corporate Bond Releases and the Prior Total Bond Releases remain unchanged. The Funds will continue to comply with all initial and continued listing requirements under NYSE Arca Equities Rule 8.600.

The Exchange further represents that the trading in the Shares will be subject to the existing trading surveillances administered by the Exchange, as well as cross-market surveillances administered by FINRA, on behalf of the Exchange, which are designed to detect violations of Exchange rules and applicable federal securities laws.^[16] The Exchange represents that these procedures are adequate to properly monitor Exchange trading of the Shares in all trading sessions and to deter and detect violations of Exchange rules and federal securities laws applicable to trading on the Exchange. The Exchange or FINRA, on behalf of the Exchange, or both, will communicate as needed regarding trading in the Shares and underlying exchange-traded options, futures, exchange-traded equity securities (including ADRs, EDRs, and GDRs), and other exchange-traded instruments with other markets and other entities that are members of the ISG, and the Exchange or FINRA, on behalf of the Exchange, or both, may obtain trading information regarding trading in the Shares and underlying exchange-traded options, futures, exchange-traded equity securities (including ADRs, EDRs, and GDRs), and other exchange-traded instruments from such markets and other entities. The Exchange may obtain information regarding trading in the Shares and underlying exchange-traded options, futures, exchange-traded equity securities (including ADRs, EDRs, and GDRs), and other exchange-traded instruments from markets and other entities that are members of ISG or with which the Exchange has in place a comprehensive surveillance sharing agreement.^[17] FINRA, on behalf of the Exchange, is able to access, as needed, trade information for the Rule 144A securities as well as certain other fixed income securities held by the Funds reported to TRACE. In addition, as stated in the Prior Corporate Bond Releases and the Prior Total Bond Releases, investors have ready access to information regarding the Funds' holdings, the Portfolio Indicative Value, the Disclosed Portfolio, and quotation and last-sale information for the Shares.

The Exchange also represents that all statements and representations made in this filing and the Prior Corporate Bond Releases and Prior Total Bond Releases regarding (a) the description of the Funds' respective portfolios, (b) limitations on portfolio holdings or reference assets, or (c) the applicability of Exchange rules and surveillance procedures shall constitute continued listing requirements for listing the Shares of the Funds on the Exchange. The Adviser has represented to the Exchange that it will advise the Exchange of any failure by a Fund to comply with the continued listing requirements, and, pursuant to its obligations under section 19(g)(1) of the Act, the Exchange will monitor for compliance with the continued listing requirements. If a Fund is not in compliance with the applicable listing requirements, the Exchange will commence delisting procedures under NYSE Arca Equities Rule 5.5(m).

III. Proceedings To Determine Whether To Approve or Disapprove SR-NYSEArca-2016-70 and Grounds for Disapproval Under Consideration

The Commission is instituting proceedings pursuant to section 19(b)(2)(B) of the Act ^[18] to determine whether the proposed rule change, as modified by Amendment No. 1 thereto, 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 proposed rule change. 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 proposed rule change.

Pursuant to section 19(b)(2)(B) of the Act,^[19] the Commission is providing notice of the grounds for disapproval under consideration. The Commission is instituting proceedings to allow for additional analysis of the proposed rule change'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.” ^[20]

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, as modified by Amendment No. 1. In particular, the Commission invites the written views of interested persons concerning whether the proposal, 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, any request for an opportunity to make an oral presentation.^[21]

Start Printed Page 60764

Interested persons are invited to submit written data, views, and arguments regarding whether the proposal should be approved or disapproved by September 23, 2016. Any person who wishes to file a rebuttal to any other person's submission must file that rebuttal by October 7, 2016. The Commission asks that commenters address the sufficiency of the Exchange's statements in support of the proposal, which are set forth in the Notice,^[22] as modified by Amendment No. 1 thereto,^[23] in addition to any other comments they may wish to submit about the proposed rule change.

The Commission generally seeks comment on whether the Exchange's representations relating to the proposed portfolio holdings in Rule 144A securities are sufficient to prevent the susceptibility of the Funds to manipulation and are thereby consistent with the requirements of section 6(b)(5) of the Act, which, among other things, requires that the rules of an exchange be designed to prevent fraudulent and manipulative acts and practices and to protect investors and the public interest. In particular, the Commission seeks comment on the following:

As described above, the Exchange has proposed that each Fund be permitted to include Rule 144A securities within a Fund's principal investments in debt securities. As a result of the proposed change, each Fund would be permitted to invest 100% of its principal investments in Rule 144A securities. The Exchange also provides that all of the Rule 144A securities in which a Fund invests will be corporate debt securities for which transactions are reported in TRACE. Rule 144A securities are restricted securities, which, as described above, are subject to legal restrictions on their sale and generally are sold in privately negotiated transactions, pursuant to an exemption from registration under the Securities Act, or in a registered public offering. The Exchange has not proposed additional quantitative criteria with respect to minimum liquidity or minimum diversification measures to be applied to the Rule 144A securities. Do commenters have views on whether the specific Rule 144A securities in which each Fund may invest would be sufficiently liquid and sufficiently diversified so as to reduce the extent to which Managed Fund Shares holding principally restricted securities may be susceptible to manipulation?
