Abstract

The Securities and Exchange Commission ("Commission") is proposing to amend Rule 3b-16 under Securities Exchange Act of 1934 ("Exchange Act"), which defines certain terms used in the statutory definition of "exchange" under Section 3(a)(1) of the Exchange Act to include systems that offer the use of non-firm trading interest and communication protocols to bring together buyers and sellers of securities. In addition, the Commission is re-proposing amendments to its regulations under the Exchange Act that were initially proposed in September 2020 for ATSs to take into consideration systems that may fall within the definition of exchange because of the proposed amendments and operate as an ATS. The Commission is re-proposing, with certain revisions, amendments to its regulations for ATSs that trade government securities as defined under Section 3(a)(42) of the Exchange Act ("government securities") or repurchase and reverse repurchase agreements on government securities ("Government Securities ATSs"). The Commission is also proposing to amend Form ATS-N for NMS Stock ATSs, which would require existing NMS Stock ATSs to amend their existing disclosures. In addition, the Commission is proposing to amend the fair access rule for ATSs. The Commission is also proposing to require electronic filing of and to modernize Form ATS-R and Form ATS, which would require existing Form ATS filers to amend their existing disclosures. Further, the Commission is re-proposing amendments to its regulations regarding systems compliance and integrity to apply to ATSs that meet certain volume thresholds in U.S. Treasury Securities or in a debt security issued or guaranteed by a U.S. executive agency, or government-sponsored enterprise ("Agency Securities").

Amendments Regarding the Definition of ``Exchange'' and 
Alternative Trading Systems (ATSs) That Trade U.S. Treasury and Agency 
Securities, National Market System (NMS) Stocks, and Other Securities

AGENCY: Securities and Exchange Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Securities and Exchange Commission (``Commission'') is 
proposing to amend Rule 3b-16 under Securities Exchange Act of 1934 
(``Exchange Act''), which defines certain terms used in the statutory 
definition of ``exchange'' under Section 3(a)(1) of the Exchange Act to 
include systems that offer the use of non-firm trading interest and 
communication protocols to bring together buyers and sellers of 
securities. In addition, the Commission is re-proposing amendments to 
its regulations under the Exchange Act that were initially proposed in 
September 2020 for ATSs to take into consideration systems that may 
fall within the definition of exchange because of the proposed 
amendments and operate as an ATS. The Commission is re-proposing, with 
certain revisions, amendments to its regulations for ATSs that trade 
government securities as defined under Section 3(a)(42) of the Exchange 
Act (``government securities'') or repurchase and reverse repurchase 
agreements on government securities (``Government Securities ATSs''). 
The Commission is also proposing to amend Form ATS-N for NMS Stock 
ATSs, which would require existing NMS Stock ATSs to amend their 
existing disclosures. In addition, the Commission is proposing to amend 
the fair access rule for ATSs. The Commission is also proposing to 
require electronic filing of and to modernize Form ATS-R and Form ATS, 
which would require existing Form ATS filers to amend their existing 
disclosures. Further, the Commission is re-proposing amendments to its 
regulations regarding systems compliance and integrity to apply to ATSs 
that meet certain volume thresholds in U.S. Treasury Securities or in a 
debt security issued or guaranteed by a U.S. executive agency, or 
government-sponsored enterprise (``Agency Securities'').

---------------------------------------------------------------------------

I. Introduction

    In September 2020, the Commission issued a proposal to amend 
Regulation ATS and Regulation SCI for Government Securities ATSs 
(``2020 Proposal'').\4\ The Commission recognized the critical role of 
government securities in the U.S. and global economy, the significant 
volume in government securities transacted on systems currently 
operating as ATSs, and these ATSs' growing importance to investors and 
overall securities market structure. Notwithstanding their importance 
for government securities, the investor protection and fair and orderly 
market principles of Regulation ATS have limited application to 
Government Securities ATSs.\5\ For

[[Page 15497]]

example, an ATS that limits its securities activities to government 
securities or reverse repurchase agreements on government securities 
(``repos'') and registers as a broker-dealer or is a bank (i.e., a 
Currently Exempted Government Securities ATS) is exempt from exchange 
registration and is not required to comply with Regulation ATS. 
Further, ATSs that trade both government securities and non-government 
securities (e.g., corporate bonds) are subject to Regulation ATS but 
are not required to comply with many of its investor protection and 
fair and orderly markets provisions, including public transparency 
rules and the obligation to provide fair access to investors if the ATS 
has significant trading volume. In addition, ATSs that trade government 
securities are not subject to the systems integrity provisions of 
Regulation SCI.
---------------------------------------------------------------------------

    \4\ See Securities Exchange Act Release No. 90019 (September 28, 
2020), 85 FR 87106 (December 31, 2020).
    \5\ For the purposes of this re-proposal, the term ``Government 
Securities ATS'' refers to an ATS that trades government securities 
or repos and includes ATSs that would be subject to Regulation ATS 
after the effective date of any final rule. This term includes three 
categories of ATSs. First, a ``Currently Exempted Government 
Securities ATS'' means an ATS that trades government securities or 
repos, is operating as of the effective date of any final rule, and 
was formerly not required to comply with Regulation ATS under 17 CFR 
240.3a1-1(a)(3) (Exchange Act Rule 3a1-1(a)(3)) exemption prior to 
the effective date of any final rule. Second, a ``Current Government 
Securities ATS'' means an ATS that trades government securities or 
repos and is operating pursuant to an initial operation report on 
Form ATS on file with the Commission as of the effective date of any 
final rule. Finally, when referring to regulatory requirements after 
the effective date of any final rule, the term ``Government 
Securities ATS'' also includes a Communication Protocol System that 
trades U.S. Government securities or repos on U.S. Government 
securities and that chooses to operate as an ATS after the effective 
date of any final rule. A ``Communication Protocol System'' would 
include a system that offers protocols and the use of non-firm 
trading interest to bring together buyers and sellers of securities. 
The re-proposal also uses the term ``Legacy Government Securities 
ATS,'' which includes all ATSs that trade government securities or 
repos and are operating as of the effective date of any final rule, 
regardless of whether the ATSs are operating pursuant to an initial 
operation report on Form ATS on file with the Commission (i.e., all 
Current Government Securities ATSs and Currently Exempted Government 
Securities ATSs).
---------------------------------------------------------------------------

    To promote operational transparency, investor protection, system 
integrity, fair and orderly markets, and regulatory oversight for 
Government Securities ATSs, the Commission proposed in the 2020 
Proposal to: Eliminate the exemption from compliance with Regulation 
ATS for Currently Exempted Government Securities ATSs; require all 
Government Securities ATSs to publicly file Form ATS-G, on which they 
would disclose information about their operations and potential 
conflicts of interest; provide a process for the Commission to review 
Form ATS-G disclosures for clarity, completeness, and potential 
violations of law and, if necessary, declare ineffective Form ATS-G 
filings; and require an ATS that has significant volume for U.S. 
Treasury Securities or Agency Securities to: (1) Establish reasonable 
standards for access to the ATS and apply those standards to all 
prospective and current subscribers in a fair and non-discriminatory 
manner pursuant Rule 301(b)(5) of Regulation ATS (``Fair Access 
Rule''); and (2) comply with the operational capability, security, 
business continuity planning, incident reporting, and related 
requirements under Regulation SCI.\6\ The Commission issued a concept 
release (``Concept Release'') in addition to the 2020 Proposal on the 
regulation of fixed income electronic trading platforms.\7\ The Concept 
Release requested comments on a wide range of topics, including the 
different regulatory treatment among fixed income electronic trading 
platforms that use diverse trading protocols or business models and 
various aspects of government securities, corporate bonds, and 
municipal securities trading, including their operations, services, 
fees, market data, and participants.
---------------------------------------------------------------------------

    \6\ The Commission also had proposed to amend Regulation ATS to: 
Require that Form ATS and Form ATS-R be filed with the Commission 
electronically through the Electronic Data Gathering, Analysis and 
Retrieval (EDGAR) system and modernize both forms; eliminate 
confidential treatment of the types of securities that an ATS trades 
as disclosed on the ATS's Form ATS and Form ATS-R; update and 
correct Form ATS-N; change the reasons for which the Commission 
could extend the initial Form ATS-N review period; require NMS Stock 
ATSs to post on their websites the most recently disseminated Form 
ATS-N, except for any amendment that the Commission has declared 
ineffective or that has been withdrawn; and remove the exclusion 
from compliance with the Fair Access Rule and Rule 301(b)(6) under 
Regulation ATS for an ATS that matches non-displayed customer orders 
using prices disseminated by an effective transaction reporting 
plan.
    \7\ See 2020 Proposal, supra note 4.
---------------------------------------------------------------------------

    The Commission received comments in response to the 2020 Proposal 
and Concept Release.\8\ Commenters expressed broad support for the 2020 
Proposal. In general, commenters supported the proposed requirements to 
remove the exemption for Currently Exempted Government Securities ATSs 
and to require public disclosures on Form ATS-G.\9\ However, some 
commenters expressed concern regarding aspects of the 2020 Proposal, 
including the proposed enhanced disclosure requirements and 
effectiveness regime \10\ and the proposal to require Government 
Securities ATSs that meet certain volume thresholds to register as 
national securities exchanges.\11\ In addition, commenters who opined 
on the Fair Access Rule and Regulation SCI had differing views about 
whether and how to apply them to Government Securities ATSs.\12\

---------------------------------------------------------------------------

    In addition, the Commission received substantial comment on the 
Concept Release, in particular concerning the regulatory framework for 
fixed income electronic trading platforms. Many commenters recognized 
that certain electronic trading platforms for fixed income securities 
are not regulated as registered exchanges or ATSs despite performing 
the same market function as those regulated markets.\13\ Several 
commenters expressed support for the Commission to expand the scope of 
its exchange regulation to encompass more fixed income platforms,\14\ 
while several other commenters believed that such action is not 
necessary or appropriate.\15\

---------------------------------------------------------------------------

    Advances in technology and innovation since Regulation ATS was 
adopted in 1998 \16\ have changed the methods by which securities 
markets bring together buyers and sellers of

[[Page 15498]]

securities. As discussed further below, innovations in trading 
protocols have increased efficiencies and access to discover liquidity 
and prices, search for a counterparty, and agree upon the terms of a 
trade. Instead of using exchange markets that offer only the use of 
firm orders and provide matching algorithms, market participants are 
able to connect to numerous Communication Protocol Systems, which offer 
the use of protocols and non-firm trading interest to bring together 
buyers and sellers of securities. Communication Protocol Systems today 
perform similar market place functions of bringing together buyers and 
sellers as registered exchanges and ATSs and have become an 
increasingly preferred choice of trading venue, particularly for fixed 
income securities. However, as a function of how Exchange Act Rule 3b-
16 currently defines the terms in Section 3(a)(1) of the Exchange Act, 
Communication Protocol Systems do not fall within the definition of 
exchange. As a result, Communication Protocol Systems are not subject 
to the same regulatory requirements as registered exchanges and ATSs 
and the investors using them do not receive the investor protection, 
fair and orderly markets, transparency, and oversight benefits stemming 
from exchange regulation. Further, by Communication Protocol Systems 
falling outside the definition of exchange, a disparity has developed 
among similar markets that bring together buyers and sellers of 
securities, in which some are regulated as exchanges and others are 
not. This regulatory disparity can create a competitive imbalance and a 
lack of investor protections.\17\
---------------------------------------------------------------------------

    \16\ See Regulation ATS Adopting Release, infra note 31.
    \17\ See infra Section VIII.C.3.a.
---------------------------------------------------------------------------

    Given the changing conditions among markets to bring together 
buyers and sellers of securities, and taking into consideration comment 
letters submitted in response to the 2020 Proposal and the Concept 
Release, the Commission is proposing to amend Exchange Act Rule 3b-16 
regarding what ``shall be considered to constitute, maintain, or 
provide `a market place or facilities for bringing together purchasers 
and sellers of securities or for otherwise performing with respect to 
securities the functions commonly performed by a stock exchange' as 
those terms are used'' in the statutory definition of ``exchange'' 
under Exchange Act Section 3(a)(1).\18\ The proposed amendments to 
Exchange Act Rule 3b-16(a) would include Communication Protocol Systems 
that make available for trading any type of security, including, among 
others, government securities, corporate bonds, municipal securities, 
NMS stocks, equity securities that are not NMS stocks, private 
restricted securities, repurchase agreements and reverse repurchase 
agreements, foreign sovereign debt, and options. Including 
Communication Protocol Systems within the definition of ``exchange'' 
would appropriately regulate a market place that brings together buyers 
and sellers of securities, extend the benefits of the exchange 
regulatory framework to investors that use such systems, and reduce 
regulatory disparities among like markets.
---------------------------------------------------------------------------

    \18\ 17 CFR 240.3b-16(a).
---------------------------------------------------------------------------

    In addition, because the Commission is proposing to amend Exchange 
Act Rule 3b-16 to include Communication Protocol Systems within the 
definition of exchange and taking into consideration comments received 
in response to the 2020 Proposal and the Concept Release, the 
Commission is re-proposing and revising previously proposed amendments 
to Regulation ATS and Regulation SCI for Government Securities ATSs 
that include the following: \19\ (1) Re-proposing to eliminate the 
exemption from compliance with Regulation ATS for an ATS that trades 
only government securities or repos and is operated by a broker-dealer 
or is a bank; (2) re-proposing, with certain revisions, to require a 
Government Securities ATS that has significant volume for U.S. Treasury 
Securities or Agency Securities to comply with the Fair Access Rule 
under Regulation ATS and Regulation SCI; \20\ (3) re-proposing to apply 
the enhanced disclosure and filing requirements of Rule 304 of 
Regulation ATS, which are currently applicable to NMS Stock ATSs, to 
all Government Securities ATSs; (4) proposing to require Government 
Securities ATSs to file Form ATS-N, as revised, instead of previously 
proposed Form ATS-G; \21\ (5) proposing several changes to Form ATS-N 
that would be applicable to both Government Securities ATSs and NMS 
Stock ATSs, including questions about the ATS's interaction with 
related markets, liquidity providers, and activities the ATS undertakes 
to surveil and monitor its market; (6) proposing amendments to Form 
ATS-N that would require existing NMS Stock ATSs to file an amendment 
to their existing disclosures on Form ATS-N; (7) proposing to add a new 
type of amendment to Form ATS-N to report changes to fee disclosures; 
(8) proposing to amend the Form ATS-N review and effectiveness process 
to permit the Commission to extend the review period for Form ATS-N 
amendments; \22\ (9) proposing to make certain changes to the Fair 
Access Rule that would apply to all ATSs that are subject to the rule; 
\23\ and (10) re-proposing electronic filing of Form ATS-R and Form ATS 
and proposing certain changes to the categories of securities reported 
on Form ATS-R.\24\
---------------------------------------------------------------------------

    \19\ U.S. Treasury Securities and Agency Securities are not 
classes of securities for purposes of Exchange Act Rule 3a1-1(b).
    \20\ The Commission is re-proposing to amend Regulation ATS to 
require that Form ATS and Form ATS-R be filed with the Commission 
electronically through EDGAR and to modernize both forms; eliminate 
confidential treatment of the types of securities that an ATS trades 
as disclosed on the ATS's Form ATS and Form ATS-R; and remove the 
exclusion from compliance with the Fair Access Rule and Rule 
301(b)(6) under Regulation ATS for an ATS that matches non-displayed 
customer orders using prices disseminated by an effective 
transaction reporting plan. Covered ATSs would not be required to 
post on their websites the most recently disseminated Form ATS-N, 
but would be required to provide pursuant to Rule 304(b)(3)(i) a 
direct URL hyperlink to the Commission's website that contains the 
documents made public by the Commission under Rule 304(b)(2).
    \21\ In the 2020 Proposal, the Commission proposed that 
Government Securities ATSs file proposed Form ATS-G. Given the 
significant overlap between proposed Form ATS-G and existing Form 
ATS-N, the Commission is now proposing that Government Securities 
ATSs file Form ATS-N, which is currently filed by NMS Stock ATSs, 
and proposing to revise Form ATS-N to apply disclosures for 
Government Securities ATSs that would fall under the proposed 
definition of ``exchange.'' See Appendix A for the proposed 
revisions to Form ATS-N. The Commission believes that this would 
limit the number of unique forms and simplify filing requirements.
    \22\ The Commission is also re-proposing to change the reasons 
for which the Commission could extend the initial Form ATS-N review 
period. See infra Section IV.A.
    \23\ See infra Section V.A.
    \24\ See infra Section V.B.
---------------------------------------------------------------------------

II. Proposed Amendments Regarding the Definition of Exchange

A. Exchange Regulatory Framework

    Exchange Act Section 3(a)(1) states that the term ``exchange'' 
means any organization, association, or group of persons, whether 
incorporated or unincorporated, which constitutes, maintains, or 
provides a market place or facilities for bringing together purchasers 
and sellers of securities or for otherwise performing with respect to 
securities the functions commonly performed by a stock exchange as that 
term is generally understood, and includes the market place and the 
market facilities maintained by such exchange.\25\
---------------------------------------------------------------------------

    \25\ See 15 U.S.C. 78c(a)(1).
---------------------------------------------------------------------------

    Section 5 of the Exchange Act \26\ requires an organization, 
association, or

[[Page 15499]]

group of persons that meets the definition of ``exchange'' under 
Section 3(a)(1) of the Exchange Act,\27\ unless otherwise exempt, to 
register with the Commission as a national securities exchange pursuant 
to Section 6 of the Exchange Act.\28\ As discussed further below, 
registered national securities exchanges are self-regulatory 
organizations (``SROs''),\29\ and must comply with regulatory 
requirements applicable to both national securities exchanges and 
SROs.\30\
---------------------------------------------------------------------------

    \26\ 15 U.S.C. 78e.
    \27\ See infra note 31.
    \28\ 15 U.S.C. 78f. A ``national securities exchange'' is an 
exchange registered as such under Section 6 of the Exchange Act.
    \29\ Section 3(a)(26) of the Exchange Act defines a self-
regulatory organization as any national securities exchange, 
registered securities association, registered clearing agency, or 
(with limitations) the Municipal Securities Rulemaking Board 
(``MSRB''). See 15 U.S.C. 78c(a)(26). See also Securities Exchange

---------------------------------------------------------------------------

    In the Exchange Act, Congress provided a broad definition of the 
term ``exchange,'' permitting the Commission to apply the definition 
flexibly as the securities markets evolve over time.\31\ In 1998, the 
Commission adopted Regulation ATS.\32\ At that time, the Commission 
recognized that advances in technology had increasingly blurred the 
line between exchange and broker-dealer activities \33\ and that ATSs 
that existed then were used by market participants as functional 
equivalents of exchanges.\34\ To more accurately describe the range of 
markets that performed exchange functions at that time, the Commission 
concurrently adopted Exchange Act Rule 3b-16 to define terms \35\ used 
in the statutory definition of ``exchange'' under Exchange Act Section 
3(a)(1).
---------------------------------------------------------------------------

    \31\ See Securities Exchange Act Release No. 40760 (December 8, 
1998), 63 FR 70844, 70850 and 70898 (December 22, 1998) 
(``Regulation ATS Adopting Release''). See also 15 U.S.C. 78e and 
78f. The Commission noted that it was recognized at the time the 
Exchange Act was enacted that a regulatory structure for securities 
exchanges would ``be of little value tomorrow if it is not flexible 
enough to meet new conditions immediately as they arise and demand 
attention in the public interest.'' See Regulation ATS Adopting 
Release at 70898, n.520 (citing Commission, Report of the Special 
Study of the Securities Markets of the Securities and Exchange 
Commission, H.R. Doc. No. 95, 88th Cong., 1st Sess. Pt. 1 (1963) at

    \35\ The Commission adopted Exchange Act Rule 3b-16 under 
Section 3(b) of the Exchange Act (power to define terms). 15 U.S.C. 
78c(b).
---------------------------------------------------------------------------

    In Exchange Act Rule 3b-16(a), the Commission defined these terms, 
in light of the markets that existed at that time, to include any 
organization, association, or group of persons that: (1) Brings 
together the orders for securities of multiple buyers and sellers; and 
(2) uses established, non-discretionary methods (whether by providing a 
trading facility or by setting rules) under which such orders interact 
with each other, and the buyers and sellers entering such orders agree 
to the terms of a trade.\36\ Rule 3b-16(b) explicitly excluded certain 
systems that the Commission believed were not exchanges.\37\ 
Accordingly, a system is not included in the Commission's 
interpretation of ``exchange'' if: (1) The system fails to meet the 
two-part test in paragraph (a) of Rule 3b-16; (2) the system falls 
within one of the exclusions in paragraph (b) of Rule 3b-16; or (3) the 
Commission otherwise conditionally or unconditionally exempts \38\ the 
system from the definition.
---------------------------------------------------------------------------

    \36\ See 17 CFR 240.3b-16(a).
    \37\ See Regulation ATS Adopting Release, supra note 31, at 
70852. Specifically, Rule 3b-16(b) excludes from the definition of 
exchange systems that perform only traditional broker-dealer 
activities, including: Systems that route orders to a national 
securities exchange, a market operated by a national securities 
association, a broker-dealer for execution, or systems that allow 
persons to enter orders for execution against the bids and offers of 
a single dealer if certain additional conditions are met.
    \38\ See 17 CFR 240.3b-16(e).
---------------------------------------------------------------------------

    When the Commission adopted Exchange Act Rule 3b-16, the Commission 
also adopted Exchange Act Rule 3a1-1(a) to exempt ATSs from the 
definition of ``exchange'' under Section 3(a)(1) of the Exchange Act. 
Exchange Act Rule 3a1-1(a)(2) \39\ exempts from the Exchange Act 
Section 3(a)(1) definition of ``exchange'' an organization, 
association, or group of persons that complies with Regulation ATS,\40\ 
which requires, among other things, meeting the definition of an ATS 
and registering as a broker-dealer.\41\ Rule 300(a) of Regulation ATS 
defines an ATS as any organization, association, person, group of 
persons, or system: (1) That constitutes, maintains, or provides a 
market place or facilities for bringing together purchasers and sellers 
of securities or for otherwise performing with respect to securities 
the functions commonly performed by a stock exchange within the meaning 
of Rule 3b-16; and (2) that does not: (i) Set rules governing the 
conduct of subscribers other than the conduct of such subscribers' 
trading on such organization, association, person, group of persons, or 
system; or (ii) discipline subscribers other than by exclusion from 
trading.\42\ Governing the conduct of or disciplining subscribers are 
functions performed by an SRO that the Commission believed should be 
regulated as such.\43\ Accordingly, pursuant to Rule 300(a), a trading 
system that performs SRO functions or functions common to national 
securities exchanges, such as establishing listing standards, is 
precluded from the definition of ATS and would be required to register 
as a national securities exchange, be operated by a national securities 
association, or seek another exemption.\44\
---------------------------------------------------------------------------

    \39\ See 17 CFR 240.3a1-1(a)(2).
    \40\ See id. Rule 3a1-1 also provides two other exemptions from 
the definition of ``exchange'' for any ATS operated by a national 
securities association and any ATS not required to comply with 
Regulation ATS pursuant to Rule 301(a) of Regulation ATS. See 17 CFR 
240.3a1-1(a)(1) and (3).
    Rule 3a1-1(b) provides an exception to the Rule 3a1-1(a) 
exemptions pursuant to which the Commission may require a trading 
system that is a substantial market to register as a national 
securities exchange, if the Commission finds doing so is necessary 
or appropriate in the public interest or consistent with the 
protection of investors. See 17 CFR 240.3a1-1(b). See also 
Regulation ATS Adopting Release, supra note 31, at 70857-58.
    \41\ See 17 CFR 242.300(a); 17 CFR 242.301(a); and 17 CFR 
242.301(b)(1). In addition to the other requirements of Regulation 
ATS, to qualify for the Rule 3a1-1(a) exemption, an organization, 
association, or group of persons must otherwise meet the definition 
of ``exchange.''
    \42\ See 17 CFR 242.300(a).
    \43\ See Regulation ATS Adopting Release, supra note 31, at 
70859.
    \44\ See id.
---------------------------------------------------------------------------

    As a result of the exemption, an ATS that complies with Regulation 
ATS is not required by Section 5 of the Exchange Act to register as a 
national securities exchange, is not an SRO, and, therefore, is not 
required to comply with regulatory requirements applicable to national 
securities exchanges and SROs.\45\ An ATS that fails to comply with the 
requirements of Regulation ATS would no longer qualify for the 
exemption provided under Rule 3a1-1(a)(2), and thus, risks operating as 
an unregistered exchange in violation of Section 5 of the Exchange 
Act.\46\

B. Adopting the Definition of Exchange for Evolving Market Places

1. Orders-Focused Markets Under Current Rule 3b-16
    When the Commission adopted Exchange Act Rule 3b-16(a), the 
Commission sought to more accurately describe the range of markets that 
performed exchange functions as those were understood at that time.\47\ 
In the Regulation ATS Adopting Release, the Commission observed that 
ATSs at that time provided services more akin to exchange functions 
than broker-dealer functions, such as matching counterparties' orders, 
executing trades, operating limit order books, and facilitating active 
price discovery.\48\
---------------------------------------------------------------------------

    \47\ See Regulation ATS Adopting Release, supra note 31, at 
70900.
    \48\ See id. at 70848.
---------------------------------------------------------------------------

    In the Regulation ATS Adopting Release, the Commission identified 
two elements of Exchange Act Rule 3b-16 that most accurately reflected 
the functions and uses of exchange markets at that time. These elements 
were the bringing together of orders of multiple buyers and sellers of 
securities and that trading takes place according to established, non-
discretionary rules or procedures.\49\ When considering what 
constituted an exchange at that time, the Commission focused on the 
expectations of the participants regarding how an execution would occur 
without the discretion of the operator. Because orders instruct a 
trading system to carry out the intention of participants in accordance 
with programmed trading procedures, orders, along with established, 
non-discretionary methods, contribute to how trading system 
participants could understand and expect to receive an execution.\50\ 
In addition, the Commission stated that ``an essential indication of 
the non-discretionary status of rules and procedures is that those 
rules and procedures are communicated to the systems users'' and 
``[t]hus, participants have an expectation regarding the manner of 
execution--that is, if an order is entered, it will be executed in 
accordance with those procedures and not at the discretion of a 
counterparty or intermediary.'' \51\
---------------------------------------------------------------------------

    \49\ See id. at 70900.
    \50\ For example, the Commission stated in the Regulation ATS 
Adopting Release that ``an alternative trading system that posts 
firm orders to buy and sell a security does raise a certain 
expectation of execution at those quoted prices'' and that ``[t]he 
expectation is based on the life of the outstanding orders in the 
system, rather than continuous two sided quotations published by 
specialist and market makers.'' See id. at 70899, n.532.
    \51\ See id. at 70900.
---------------------------------------------------------------------------

    Further, at the time Exchange Act Rule 3b-16(a) was adopted, most 
ATSs operating met the criteria of the rule in that they offered the 
use of orders and algorithms that matched orders.\52\ ATSs at that time 
allowed broker-dealers to place and execute orders on the system and 
the systems functioned as limit order books where orders are executed 
according to time, price, and size priority.\53\ Accordingly, orders 
and established, non-discretionary methods undergirded Exchange Act 
Rule 3b-16 to reflect functions of exchange markets at that time. When 
discussing orders in the Regulation ATS Adopting Release, however, the 
Commission stated that systems that displayed bona fide, non-firm 
trading interest \54\ or did not establish rules or operate a trading 
facility \55\ would not fall within Rule 3b-16(a).
---------------------------------------------------------------------------

    \52\ See id. at 70899-900, n.536.
    \53\ See id. at 70899, n.525.
    \54\ See id. at 70850. In the Regulation ATS Adopting Release, 
the Commission stated, ``[g]enerally, however, a system that 
displays bona fide, non-firm indications of interest--including, but 
not limited to indications of interest to buy or sell a particular 
security without either prices or quantities associated with those 
indications--will not be displaying ``orders'' and, therefore, not 
fall within Rule 3b-16.'' See id.
    \55\ See id. The Commission also stated that ``[u]nless a system 
also establishes rules or operates a trading facility under which 
subscribers can agree to the terms of their trades, the system will 
not be included within Rule 3b-16, even if it brings together 
`orders.' '' See id.
---------------------------------------------------------------------------

2. Prevalence of Systems Offering Non-Firm Trading Interest and 
Structured Protocols
    Advances in technology have facilitated innovations and more 
efficient or diverse methods to bring together buyers and sellers of 
securities.\56\ In the Commission's experience, Communication Protocol 
Systems, which can use various technologies and connectivity, generally 
offer the use of non-firm trading interest and establish protocols to 
prompt and guide buyers and sellers to communicate, negotiate, and 
agree to the terms of the trade without relying solely on the use of 
orders. Below is a non-exhaustive list of some Communication Protocol 
Systems.
---------------------------------------------------------------------------

    \56\ See id. at 70848.
---------------------------------------------------------------------------

    One example of a Communication Protocol System is a ``Request-for-
Quote'' (``RFQ'') system. RFQ systems are designed to allow market 
participants to obtain quotes for a particular security by sending 
messages to one or multiple potential respondents on the system 
simultaneously. RFQ systems may be ``disclosed,'' in which case the 
participants with established relationships interact only with each 
other, or anonymous, in which case the parties may not have established 
relationships. The system provider requires a participant to enter 
information in a message, which may include the name of the initiator, 
Committee on Uniform Securities ldentificalion Procedures (CUSIP) 
number, side, and size. The system provider also provides protocols for 
participants to communicate with each other and negotiate a price or 
size of a trade. For example, participants receiving an RFQ message can 
choose to interact with the initiator by responding within a time 
period designated by the system provider with a priced quote. These 
methods can serve the same function as auctions where the respondents 
compete to offer the best price. The initiator can then select among 
the quote responses that it wishes to interact with through the system 
by either accepting one of multiple responses or rejecting all 
responses within a period of time set by the system provider. The match 
of the request and response results in an agreement to the terms of the 
trade between a buyer and a seller, which then proceeds to post-trade 
processing.\57\ An RFQ list protocol (``RFQ List''), which is a form of 
RFQ protocol used commonly to trade U.S. Treasury Securities, may 
include a collection of RFQ inquiries that are submitted as a group but 
priced as individual items.\58\ The RFQ List (defined by each system 
provider but generally more than two listed items) may be executed in 
its entirety, in pieces, or not at all. A liquidity provider that is 
responding to the list request may apply a ``good for'' time that is 
associated with the executable prices provided.
---------------------------------------------------------------------------

    \57\ Communication Protocol Systems also may offer a workup 
functionality or blotter scraping functionality to gather non-firm 
trading interest and facilitate the negotiation and execution of 
trades. In a workup, a system may have a private phase, where the 
two original contra-parties submitting orders can negotiate, and a 
public phase where all subscribers can submit orders at the workup 
price.
    \58\ An RFQ List may be referred to as a Bid Wanted in 
Competition (``BWIC'') or Offer Wanted in Competition (``OWIC'') in 
the corporate bond market. Both serve a similar purpose to the RFQ 
List in allowing the submitter to solicit bids and offers on a 
number of securities at one time.
---------------------------------------------------------------------------

    A Communication Protocol System could also include a system that 
electronically displays continuous firm or non-firm trading interest, 
or ``stream axes,'' in a security or type of security to participants 
on the system. Axes typically represent an indication of

[[Page 15501]]

interest to sell or buy a bond (but can include firm quotes), and can 
either serve as a starting point for negotiation between participants 
or be executed immediately. Systems that stream axes take many forms. 
Some system providers provide connectivity and protocols for 
participants to electronically communicate and negotiate the terms of a 
trade. Other system providers offer participants more automated 
processes, whereby participants auto-execute against a streamed quote 
and agree upon the terms of a trade without negotiation. Typically, the 
system is programmed with permission options to allow participants to 
decide who can or cannot receive their axes. In such a case, the 
trading interest exchanged between the parties is typically firm and 
functions as orders.
    Conditional order systems may be Communication Protocol Systems 
that offer the use of trading interest that may not be executable until 
after a user takes subsequent action. For example, a system provider 
may require conditional orders to contain a symbol, side, and size and 
provide protocols for participants to send and receive invitation 
messages to trade. The system would be designed for conditional orders 
to match with other trading interest, which can either be a firm order 
or another non-firm conditional order.\59\ Upon a match, the system may 
send a firm-up invitation messages to both participants. The system 
protocols may permit a participant using a conditional order to either 
decline the firm-up invite, accept the firm-up invite, or counter the 
response to firm up.\60\ During the time that the parties' trading 
interest is matched until the invitation to firm-up expires, is 
canceled, is executed, or is declined, the system protocols may require 
that the non-firm trading interest be committed and the shares cannot 
trade elsewhere.\61\ Using the system protocols, the matched parties 
can modify the attributes of the non-firm trading interest (i.e., 
price, size) before accepting the firm-up invitation. To the extent 
either a seller or buyer changes the attributes, an execution will only 
occur if each contra-party's corresponding attributes will still be 
met. If both matching parties accept the firm-up invite, the parties 
would agree upon the terms of the trade and an execution would occur.
---------------------------------------------------------------------------

    \59\ Based on Commission staff experience, some NMS Stock ATSs 
disclose protocols to allow conditional orders to interact with the 
ATS's limit order book, thereby increasing the interaction among 
potential buyers and sellers and access to liquidity.
    \60\ An order resting on an ATS limit order book that can 
interact with a conditional order does not receive a firm-up invite 
and therefore does not send firm-up responses.
    \61\ Many conditional order and RFQ systems monitor their 
participants' firm-up rates and may limit or deny the use of the 
system by a participant if the participant's firm-up rate falls 
below a certain percentage. While the system provider typically 
monitors these firm-up rates to help ensure that participants do not 
abuse the system, such monitoring and actions taken against 
participants for not firming-up may incentivize participants to not 
back away. Thus, conditional orders or RFQs can be firm in practice 
and in this way may meet the definition of order under current 
Regulation ATS. See 17 CFR 242.300(e) (``any firm indication of a 
willingness to buy or sell a security'').
---------------------------------------------------------------------------

    Other systems have developed to bring together buyers and sellers 
of securities through the use of bilateral negotiation protocols and 
non-firm trading interest. Negotiation systems focus on providing a 
forum for buyers and sellers to see displayed non-firm trading 
interest, access liquidity, find a counterparty, and negotiate a trade 
through the use of their communication technology. The system may allow 
participants to select certain pre-approved participants and then 
exchange messages for purposes of agreeing to the terms of a trade. 
Negotiation systems may have fewer parameters for communicating trading 
interest than RFQ protocols; for example, negotiation systems provide 
features that are designed to prompt participants to interact with each 
other and provide parameters around that interaction, such as time for 
responses or requirements on the content of the message. A system may 
``scrape'' or obtain the symbol of trading interest that a participant 
is seeking from the participant's order management or execution 
management system and use that to alert other participants on its 
system about potential contra-side interest in seeking to initiate a 
negotiation. The market participants using negotiation systems may 
complete a transaction outside of the system.
    As trading in securities has become more electronic, Communication 
Protocol Systems perform the function of a market place and have become 
a preferred method for market participants to discover prices, find a 
counterparty, and execute a trade, particularly for government 
securities and other fixed income markets. One commenter on the 2020 
Proposal and Concept Release, for example, stated that multilateral 
trading venues using RFQ protocols are some of the most significant 
multilateral trading venues operating in fixed income markets regulated 
by the Commission, including the U.S. Treasury market.\62\ This 
commenter stated that RFQ trading venues dominate the dealer-to-
customer segment of the U.S. Treasury market and in the aggregate 
account for approximately 50 percent of total electronic trading volume 
on multilateral U.S. Treasury trading venues.\63\ Another large 
electronic trading venue for fixed income products estimated that its 
average daily volume using an RFQ protocol increased from $223 million 
in the second quarter of 2017 to $1.17 billion in the second quarter of 
2021.\64\ Systems offering conditional order protocols have increased 
over the past several years, particularly for trading NMS stocks. 
Today, 26 NMS Stock ATSs have disclosed on their public Form ATS-N that 
they send or receive messages indicating trading interest, such as 
conditional orders.
---------------------------------------------------------------------------

    \62\ See Citadel Letter at 1-2.
    \63\ See id. This commenter noted that multilateral RFQ trading 
venues are formally registered in other asset classes and 
jurisdictions, and that there are ``well-established precedents'' to 
delineate the scope of multilateral trading venues subject to 
regulation.
    \64\ Tradeweb Investor Presentation, July 2021, available at: 
<a href="https://investors.tradeweb.com/static-files/e63caabf-d71d-46c0-9589-353fb8b93388">https://investors.tradeweb.com/static-files/e63caabf-d71d-46c0-9589-353fb8b93388</a>.
---------------------------------------------------------------------------

    Communication Protocol Systems, like registered exchanges and ATSs, 
offer their participants several benefits, including reducing 
counterparty search costs, bringing together diverse market 
participants, and making it efficient and simple to find a counterparty 
and agree upon the terms of a trade. These systems improve price 
discovery from the voice protocols that were used more widely in the 
fixed income market in the past by offering participants systems and 
protocols that are specifically designed to allow participants to 
contact, and receive responses from, multiple potential counterparties 
at one time, as opposed to the more time-consuming process of calling 
each potential counterparty individually. RFQ protocols, for example, 
allow an initiator to share and attempt to trade its entire trading 
interest all at once. In contrast, under a limit order book model, for 
example, the seeker of liquidity may find it can only execute its 
trading interest in a piecemeal fashion. RFQs also allow initiators to 
more easily demonstrate that they attempted to achieve best execution 
by showing that the initiator sent requests for quotes to multiple 
dealers for a security. In addition, participants may find conditional 
orders attractive when seeking to trade at size or to avoid information 
leakage.
    While Communication Protocol Systems may bring together buyers and 
sellers for all types of securities and allow participants to negotiate 
a trade,

[[Page 15502]]

they are particularly useful to market participants to trade less 
liquid securities, find counterparties for large size trades, and 
minimize information leakage and adverse impact of large size trades. 
For example, market participants can use Communication Protocol Systems 
to post and see non-firm trading interest on several trading venues 
simultaneously, thereby increasing their ability to find a counterparty 
and reduce search costs. When resting non-firm trading interest on a 
trading venue, market participants can use non-firm trading interest as 
a tool to avoid the risk of double-execution.\65\ Participants that use 
conditional orders, for example, may place the same trading interest at 
various trading centers in search of liquidity because it would allow 
them to accept or decline responses if they receive more than one. 
Participants may find locating a counterparty on a limit order book 
system for less liquid securities more difficult and choose instead to 
use a Communication Protocol System, such as an RFQ system, because 
such system allows the initiating participant to use non-firm trading 
interest to solicit quotes from multiple market participants for less 
liquid securities and negotiate a size or price for such securities.
---------------------------------------------------------------------------

    \65\ For example, a market participant that rests the same non-
firm trading interest on two trading venues has the ability to back 
away from one if both are lifted (i.e., preliminarily matched). In 
such case, the market participant is able to complete one trade and 
cancel or back away from the other.
---------------------------------------------------------------------------

3. Lack of Investor Protections and Disparate Regulation Among Market 
Places
    Given the changes in methods for bringing buyers and sellers 
together over the past couple of decades, the contrast between market 
place functions of exchanges that offer the use of orders and trading 
facilities and systems that offer the use of trading interest and 
protocols has become increasingly blurred. Both types of systems share 
the same business objectives and engage in similar market activities; 
however, one type of system is subject to the exchange regulatory 
framework while the other is not.\66\ Today, Communication Protocol 
Systems perform similar market place functions as registered exchanges 
and ATSs and have become venues for investors to discover prices, find 
a counterparty, and agree upon the terms of a trade. Because 
Communication Protocol Systems do not fall within the definition of 
``exchange'' and are thus not required to register as national 
securities exchanges, they are not required to comply with the same 
Federal securities laws and regulations applicable to registered 
exchanges \67\ or ATSs.\68\ Market participants use Communication 
Protocol Systems for certain advantages that these market places offer 
for trading securities; however, when doing so, market participants 
cannot avail themselves of the same investor protections, fair and 
orderly market principles, and Commission oversight that apply to 
today's registered exchanges or ATSs.\69\ This regulatory gap also 
creates disparities that affect competitive balances among like market 
places for securities.\70\ Consistent with the statutory definition of 
``exchange'' in Exchange Act Section 3(a)(1), and as discussed above, 
today Communication Protocol Systems provide a ``market place'' for 
bringing together purchasers and sellers of securities.\71\ The current 
proposal will use the flexibility granted to the Commission by Congress 
to update Exchange Act Rule 3b-16 to address these developments in the 
markets for securities, the corresponding lack of investor protections, 
and disparate regulation among these markets.\72\
---------------------------------------------------------------------------

    \66\ See U.S. Securities and Exchange Commission Fixed Income 
Market Structure Advisory Committee (``FIMSAC''), Recommendation for 
the SEC to Review the Framework for the Oversight of Electronic 
Trading Platforms for Corporate and Municipal Bonds (July 16, 2018), 
available at <a href="https://www.sec.gov/spotlight/fixed-income-advisory-committee/fimsac-electronic-trading-platforms-recommendation.pdf">https://www.sec.gov/spotlight/fixed-income-advisory-committee/fimsac-electronic-trading-platforms-recommendation.pdf</a> 
(expressing concern about regulatory harmonization among fixed 
income trading platforms, recognizing that some firms were regulated 
as ATSs, while some were regulated as broker-dealers or not 
regulated at all).
    \67\ See infra Section II.D.1.
    \68\ See infra Section II.D.2.
    \69\ See infra Section II.D.
    \70\ See infra Section VIII.C.3.a.
    \71\ See supra Section II.A.
    \72\ The Commission is not proposing to amend Exchange Act Rule 
3b-16(b), which excludes from the definition of ``exchange'' systems 
that perform only traditional broker-dealer activities, including: 
Systems that route orders to a national securities exchange, a 
market operated by a national securities association, a broker-
dealer for execution, or systems that allow persons to enter orders 
for execution against the bids and offers of a single dealer if 
certain additional conditions are met. These systems would continue 
to not fall within the definition of ``exchange.'' As discussed 
below, and consistent with the Commission's views expressed in the 
Regulation ATS Adopting Release, a broker-dealer's exercise of 
discretion and judgment over its customers' orders or trading 
interest does not make the broker-dealer an exchange. See Regulation 
ATS Adopting Release, supra note 31, at 70851. See also infra 
Section II.C.3. The Commission is proposing to add an exclusion to 
Rule 3b-16(a) for systems that allow issuers to sell their own 
securities to investors. See infra Section II.C.2. Further, as 
explained below, the Commission is not proposing to include within 
the definition of ``exchange'' a system that unilaterally displays 
trading interest without offering a trading facility or 
communication protocols to bring together buyers and sellers. Also, 
systems that provide general connectivity for persons to communicate 
without protocols, such as utilities or electronic web chat 
providers, would not fall within the definition of exchange. See id.
---------------------------------------------------------------------------

    Including Communication Protocol Systems within the definition of 
``exchange'' would provide market participants that use these market 
places with the investor protections, fair and orderly market 
principles, and Commission oversight provided by the exchange 
regulatory framework.\73\ A Communication Protocol System that chooses 
to register as an exchange would be an SRO and be subject to the 
requirements of Section 6 of the Exchange Act, as discussed further 
below.\74\ However, the Commission expects that many Communication 
Protocol Systems would choose instead to comply with the conditions of 
the Regulation ATS exemption, which includes registering as a broker-
dealer.\75\ As discussed further below, Communication Protocol Systems 
complying with Regulation ATS would also be subject to the Regulation 
ATS investor protection provisions, including the requirement to 
establish written safeguards and procedures to protect confidential 
subscriber trading information \76\ and operational transparency 
requirements of Form ATS-N for ATSs that trade NMS stocks or government 
securities or repos.\77\ They would also be subject to fair and orderly 
markets provisions under the Fair Access Rule.\78\ Registering as a 
broker-dealer would subject a Communication Protocol System to 
Commission and Financial Industry Regulatory Authority (``FINRA'') 
oversight.\79\ As a FINRA member, the Communication Protocol System 
would be subject to FINRA's investor protection and examination and 
market surveillance programs and would be required to comply with 
FINRA's trade reporting rules.

    The proposal to include Communication Protocol Systems within the 
definition of exchange would promote competition by reducing cost 
disparities and creating a more level competitive landscape.\80\ 
Several commenters in response to the Concept

[[Page 15503]]

Release expressed concerns regarding the disparity in regulatory 
treatment between exchanges, ATSs, and other fixed income 
platforms.\81\ In addition, FIMSAC expressed concern about the lack of 
regulatory harmonization among fixed income electronic trading 
platforms, recognizing that some firms are regulated as ATSs, while 
others are regulated as broker-dealers or not at all, and stated that 
these distinctions in regulatory oversight complicate efforts to 
improve the efficiency and resiliency of the fixed income electronic 
trading markets.\82\ In response to the Concept Release, one commenter 
stated that the current regulatory framework puts ATSs at a competitive 
disadvantage to non-ATS trading platforms, which are not subject to the 
same regulatory obligations designed to protect investors and the 
integrity of the fixed income markets.\83\ Another commenter stated its 
belief that disparate regulatory treatment across trading platforms 
impacts market efficiency and competition and introduces potential 
resiliency risks.\84\ Another commenter stated that electronic 
platforms for bringing together buyers and sellers of fixed income 
securities for the purpose of effecting transactions should generally 
be regulated the same regardless of how they are structured 
internally.\85\ The Commission recognizes that the regulatory costs 
associated with registering and operating as a registered exchange are 
higher than the regulatory costs associated with registering as a 
broker-dealer and complying with Regulation ATS. However, Communication 
Protocol Systems operating outside the exchange regulatory framework 
are subject to neither national securities exchange nor ATS regulatory 
costs and therefore have an advantage when competing against other 
markets that also bring together buyers and sellers of securities.\86\ 
As discussed further in Section VIII, a trading system that performs an 
exchange market function but is not subject to the exchange regulatory 
regime could receive a competitive advantage because such systems are 
not subject to the compliance costs to which regulated exchanges are 
subject.

trading platforms, as well as potential regulatory gaps, flowing in 
part from the definitions and guidance adopted in 1998 in Regulation 
ATS). The commenter stated its belief that it would be beneficial 
for the Commission to provide guidance that specifically addresses 
the characteristics of RFQ trading systems and evaluate whether they 
meet the ``exchange'' definition for purposes of Regulation ATS.
    \86\ See infra Section VIII.C.3.a.i.
---------------------------------------------------------------------------

    Amending Exchange Act Rule 3b-16(a) to include non-firm trading 
interest would eliminate the possibility that systems may offer the use 
of non-firm trading interest that, in practice, functions as firm 
orders, so as to avoid exchange registration or complying with 
Regulation ATS. In the Regulation ATS Adopting Release, the Commission 
expressed concern that system providers may label trading interest that 
is firm in practice as non-firm.\87\ The providers of such systems may 
take the position that their systems arguably do not use ``orders'' and 
thus do not fall within the criteria of Rule 3b-16. For example, 
systems that offer the use of non-firm trading interest may monitor 
participants' firm-up rates in response to a quote they received and 
may penalize a participant with a low firm-up rate either economically 
or by limiting its ability to use features of its system. Such 
activities could cause participants on the systems to believe that 
trading interest that they submit or receive is effectively firm and 
affect their behavior on the system. The difference between what is a 
firm order and what is not requires careful scrutiny of the design of 
the system, the trading interest offered, and what actually takes place 
among buyers and sellers interacting on the systems. The Commission 
believes, however, that the use of firm or non-firm trading interest by 
a system should no longer be a factor in determining whether a system 
performs the function of a market place because both firm and non-firm 
trading interest can be used by a system with the same purpose and 
effect to bring together buyers and sellers of securities.\88\
---------------------------------------------------------------------------

    \87\ See Regulation ATS Adopting Release, supra note 31, at 
70850.
    \88\ See supra Section II.B.2.
---------------------------------------------------------------------------

    Finally, for clarity, Exchange Act Rule 3b-16(a) would continue to 
encompass systems that make available for trading any type of security. 
The definition of ``exchange'' under Section 3(a)(1) of the Exchange 
Act and current Exchange Act Rule 3b-16(a) applies to all securities, 
including government securities, corporate bonds, municipal securities, 
NMS stocks, equity securities that are not NMS stocks, private 
restricted securities, repurchase agreements and reverse repurchase 
agreements, foreign sovereign debt, and options, and does not exempt or 
exclude any security or type of securities. The Commission believes 
that it is important for any system that falls within the criteria of 
Rule 3b-16(a) to be subject to the exchange regulatory framework, 
notwithstanding how thinly traded or novel a security may be, and 
participants on such systems should be able to avail themselves of the 
same benefits that participants on registered exchanges or ATSs 
receive. Accordingly, the proposed amendments to Rule 3b-16(a) do not 
change the Commission's interpretation of the statutory definition of 
``exchange''--that is, it applies to all securities.
    The Commission received several comments in response to the Concept 
Release expressing reservations about revising Exchange Act Rule 3b-16 
to include certain fixed income markets within the definition of 
exchange. One commenter stated that doing so would insert unnecessary 
intermediation between dealers and their customers and threaten to 
distort the market structure by creating a one-size-fits-all approach 
that is biased against the trading of less-liquid instruments, damaging 
liquidity formation.\89\ Another commenter expressed concern about the 
Commission creating additional regulatory obligations in the fixed 
income space and believed the Commission should undertake a more in-
depth review of fixed income trading, engage in discussion with the 
industry, and outline the problems that any proposed regulations are 
intended to solve before moving forward with any such regulatory 
proposal.\90\ Likewise, another commenter stated its belief that the 
Commission should not impose

[[Page 15504]]

Regulation ATS and the current exchange framework on existing and 
emerging electronic trading protocols and functionalities that do not 
meet the existing definition of an ATS or an exchange \91\ because such 
rules are better suited for regulating systems and trading practices in 
the equity markets.\92\ In addition, one commenter stated that there 
are a variety of trading protocols that have developed within the fixed 
income market--such as those that are primarily order-driven (such as 
retail-focused order books) and others that are driven by price 
requests (such as RFQs)--and that the market continues to innovate.\93\ 
This commenter stated its belief that the Commission should take into 
account these distinctions and apply a lighter regulatory approach in 
order to avoid stifling innovation.\94\
---------------------------------------------------------------------------

    \89\ See Bloomberg Letter at 17-20. This commenter specifically 
cited RFQs as a new protocol that has helped in discovering less 
liquid instruments.
    \90\ See SIFMA Letter at 11. The commenter stated its belief 
that systems that merely act as informational conduits should remain 
outside the scope of Regulation ATS.
    \91\ See ICI Letter at 2, 7. This commenter stated that, for 
example, tools that facilitate trade-related communications between 
market participants should not be subject to rules that are better-
suited for order book protocols.
    \92\ See id. at 8.
    \93\ See MarketAxess Letter at 2-4.
    \94\ See id.
---------------------------------------------------------------------------

    The Commission notes that these comments focused on the fixed 
income market exclusively. However, these comments have aided in the 
formulation of this proposal for revising the Commission interpretation 
of the definition of ``exchange,'' and the Commission looks forward to 
receiving more comments to aid in its deliberations. As a preliminary 
response to the comment letters summarized in this section, the 
Commission does not believe that the proposed amendments to Exchange 
Act Rule 3b-16 would create a one-size-fits-all model, imposing 
unnecessary intermediation between dealers and their customers,\95\ or 
import concepts from the equity markets onto emerging electronic 
trading protocols that would damage the market structure in the fixed 
income markets.\96\ Form ATS and Form ATS-N do not impose or favor any 
specific market structure or manner of trading, and the Commission is 
proposing to amend Form ATS-N to accommodate the operations of 
Communication Protocol Systems. Further, the Commission preliminarily 
does not believe that regulating fixed income systems, or systems for 
other asset classes of securities, under the exchange regulatory 
framework, particularly Regulation ATS, would stifle innovation or be 
biased against less-liquid instruments using an RFQ protocol. 
Regulation ATS is designed to be flexible enough to accommodate the 
evolving technology of ATSs and allow for systems to continue to 
innovate without the regulatory obligations of registered exchanges, 
which are SROs.\97\ In the years since its adoption in 1998, many 
systems that chose to operate under the Regulation ATS exemption have 
had varied business models, including offering RFQ protocols as part of 
their overall ATS services, for trading different types of securities, 
including, among others, government securities, corporate bonds, 
municipal securities, NMS stocks, equity securities that are not NMS 
stocks, private restricted securities, repurchase agreements and 
reverse repurchase agreements, foreign sovereign debt, and options.

---------------------------------------------------------------------------

    The Commission seeks public comment on all aspects its proposal to 
amend Exchange Act Rule 3b-16(a), the Communication Protocol Systems 
that would fall within the definition of ``exchange,'' and the existing 
exchange regulatory requirements that would apply to a Communication 
Protocol System.

C. Proposed Amendments to Exchange Act Rule 3b-16

    Today, Exchange Act Rule 3b-16 provides that an organization, 
association, or group of persons meets the definition of ``exchange'' 
if it doesn't meet one of the exceptions of the rule and it: (1) Brings 
together the orders for securities of multiple buyers and sellers; and 
(2) uses established, non-discretionary methods (whether by providing a 
trading facility or by setting rules) under which such orders interact 
with each other, and the buyers and sellers entering such orders agree 
to the terms of the trade.
    The Commission is proposing to amend Exchange Act Rule 3b-16 to, 
among other things, include non-firm indications of a willingness to 
buy or sell a security, in addition to orders, within the 
interpretation, define ``trading interest,'' add ``communication 
protocols'' as an established method that an organization, association, 
or group of persons can provide to bring together buyers and sellers of 
securities, simplify and align the rule text with the statutory 
definition of exchange under Section 3(a)(1) of the Exchange Act, and 
add an exclusion under Exchange Act Rule 3b-16(b). Accordingly, the 
Commission is proposing to amend Exchange Act Rule 3b-16 to provide 
that an organization, association, or group of persons would be 
considered to constitute, maintain, or provide an exchange if it is not 
subject to an exception under Rule 3b-16(b) and it: (1) Brings together 
buyers and sellers of securities using trading interest; and (2) makes 
available established, non-discretionary methods (whether by providing 
a trading facility or communication protocols, or by setting rules) 
under which buyers and sellers can interact and agree to the terms of a 
trade.
1. Trading Interest; Brings Together Buyers and Sellers
    The Commission is proposing to add a definition of the term 
``trading interest'' to Exchange Act Rule 3b-16 and amend the rule to 
replace ``orders'' with ``trading interest.'' The definition of trading 
interest would allow for clear and consistent application of the 
revised functional test for ``exchange'' under Rule 3b-16.
    Under the proposal, Exchange Act Rule 3b-16(a) would continue to 
apply to systems that use orders, as that term is currently defined and 
applied in Rule 3b-16(c), to bring together buyers and sellers because 
the term ``orders'' would be included in the definition of ``trading 
interest.'' ``Trading interest,'' as proposed, would include 
``orders,'' as the term is defined under Rule 3b-16(c), or any non-firm 
indication of a willingness to buy or sell a security that identifies 
at least the security and either quantity, direction (buy or sell), or 
price.\98\ Based on Commission staff experience, generally, trading 
systems have offered non-firm trading interest that included the symbol 
and one of the following: Quantity, direction, or price. For example, a 
message that is sent to system participants for an NMS stock that only 
identifies the NMS stock symbol and quantity that the participant seeks 
to trade would be considered trading interest. A message sent by a 
participant of a corporate bond system to five potential counterparties 
that only identifies the CUSIP for a bond and an instruction to buy 
would be considered trading interest, as proposed, because it contains 
the symbol and direction. If the same initiating participant only 
provided the symbol and requested a two-sided quote in response, the 
response would constitute trading interest as it would identify the 
symbol

[[Page 15505]]

and a price. Indeed, Commission staff has observed that ATSs that offer 
a negotiation functionality to bring together buyers and sellers offer 
the use of non-firm trading interest that includes the symbol and one 
of the following: Quantity, direction, or price. In addition, there are 
instances where systems offer the use of non-firm trading interest, 
such as an indication of interest, that includes the symbol and 
direction but does not explicitly include a quantity or price, which 
can be inferred from the facts and circumstances accompanying the 
trading interest.\99\ The Commission believes that a system that offers 
the use of a message that identifies the security and either the 
quantity, direction, or price would provide sufficient information to 
bring together buyers and sellers of securities because it allows a 
market participant to communicate its intent to trade and a reasonable 
person receiving the information to decide whether to trade or engage 
in further communications with the sender.\100\
---------------------------------------------------------------------------

    \98\ In conjunction with adding the defined term ``trading 
interest'' to Rule 3b-16, the Commission is proposing to add the 
definition of ``trading interest'' to Rule 300 of Regulation ATS. 
See proposed Rule 300(q). In addition, to encompass persons who 
transact in trading interest, and not only orders, the Commission is 
also proposing to change the definition of ``Subscriber'' in Rule 
300(b) to include any person submitting, disseminating, or 
displaying ``trading interest.'' See Rule 300(b), as proposed to be 
revised.
    \99\ See Regulation ATS Adopting Release, supra note 31, at 
70850.
    \100\ A system that uses trading interest to bring together 
buyers and sellers would not meet the definition of ``exchange,'' 
however, unless it also met all the elements of Rule 3b-16(a), 
including the element ``makes available established, non-
discretionary methods (whether by providing a trading facility or 
communication protocols, or by setting rules) under which buyers and 
sellers can interact and agree to the terms of a trade.''
---------------------------------------------------------------------------

    On the other hand, the Commission preliminarily believes that a 
message that only indicates the security to be traded without more 
information would not be trading interest and a system that only offers 
the use of such messages would be unlikely to bring together buyers and 
sellers and does not warrant the regulatory oversight accompanying 
classification as an exchange. Nevertheless, if a system is designed to 
permit an initiating participant to submit a message that only contains 
a symbol, yet a responding participant can submit a message that 
contains a symbol and either quantity, direction, or price that the 
initiator can accept, the message by the responding participant and 
acceptance by the initiator would be trading interest because each of 
these contain the symbol and at least direction, size, or price. As 
proposed, the revised criteria of Exchange Act Rule 3b-16(a) that 
include ``trading interest,'' as defined herein, would capture the vast 
majority of systems that bring together buyers and sellers to agree to 
the terms of a trade despite not including systems where solely the 
security is identified. If adopted, however, the Commission would 
continue to monitor market developments to ascertain whether such 
systems may warrant further regulation in the future.
    The Commission is also proposing to amend Rule 3b-16(a)(1) to 
change the reference to a system that ``brings together the orders'' to 
``brings together buyers and sellers of securities using trading 
interest.'' Systems that use non-firm trading interest allow 
participants to communicate their trading intentions, either on a 
bilateral or multilateral basis, to negotiate a trade. Unlike orders, 
non-firm trading interest typically does not interact with other non-
firm trading interest without further action by the potential 
counterparties. Rather, the potential counterparties submitting non-
firm trading interest interact with each other through the use of 
communication protocols. To provide for the use of both firm order 
interaction and participants' interaction through non-firm trading 
interest, the Commission is proposing to amend Rule 3b-16(a) to replace 
``brings together orders'' with ``brings together buyers and sellers of 
securities using trading interest.'' The phrase ``brings together 
buyers and sellers of securities using trading interest'' still 
captures systems that use orders. The Commission is not proposing to 
change the meaning of ``to bring together'' as defined in the 
Regulation ATS Adopting Release \101\ nor is the Commission proposing 
to exclude from Rule 3b-16(a) systems that use orders to bring together 
buyers and sellers of securities--such systems would still be subject 
to Rule 3b-16.
---------------------------------------------------------------------------

    \101\ See id. at 70849.
---------------------------------------------------------------------------

    The Commission is proposing to amend Exchange Act Rule 3b-16(a)(2) 
to simplify the rule text and align the rule text with the proposed 
changes to Rule 3b-16(a)(1). Specifically, the Commission is proposing 
to replace ``under which such orders interact with each other and the 
buyers and sellers entering such orders agree to the terms of a trade'' 
with ``under which buyers and sellers can interact and agree to the 
terms of a trade.'' As explained above, because the Commission is 
proposing to amend Rule 3b-16(a) to include trading interest, and is no 
longer limiting the application of the rule to orders, the focus on 
``interaction'' should be between buyers and sellers rather than 
orders. For similar reasons, the Commission is proposing to delete from 
the rule text the phrase ``the buyers and sellers entering such 
orders.'' This proposed change is designed to simplify the rule text 
and remove the reference to orders because the proposed amendments to 
Rule 3b-16(a) also include non-firm trading interest in addition to 
orders.
2. Multiple; Exclusion for Issuer Systems
    The Commission is proposing to remove the reference to securities 
of ``multiple'' buyers and sellers from Exchange Act Rule 3b-16(a)(1) 
and is proposing to codify in Rule 3b-16(b)(3) an example the 
Commission provided in the Regulation ATS Adopting Release for systems 
that allow issuers to sell their own securities to investors. These 
proposed changes are not intended to change the existing scope of Rule 
3b-16(a) but only to clarify its application.
    The term ``multiple'' was added to Rule 3b-16(a) to help reinforce 
that single counterparty systems were not included in the definition of 
``exchange.'' \102\ These systems primarily included systems used by 
issuers to sell their own securities and systems used by market makers 
registered with an SRO, which are currently specifically excluded from 
Rule 3b-16(a) under Rule 3b-16(b)(2). The Commission believes that the 
term ``multiple'' could be misconstrued to mean that RFQ systems, for 
example, do not meet the criteria of Rule 3b-16(a) because a 
transaction request typically involves one buyer and multiple sellers 
or one seller and multiple buyers.\103\
---------------------------------------------------------------------------

    \102\ See id.
    \103\ One commenter on the 2020 Proposal and Concept Release 
stated its belief that RFQ platforms do not meet the criteria of 
Rule 3b-16 because such platforms do not offer ``multiple-to-
multiple'' order interaction among participants and that the RFQ 
platforms instead facilitate trading between an individual market 
participant (requester) and potential liquidity providers 
(responders). See ICI Letter at 2, 7.
---------------------------------------------------------------------------

    Under current Rule 3b-16(a), whether a system meets the 
``multiple'' prong depends on whether the system, when viewed in its 
entirety, includes more than one buyer and more than one seller and is 
not determined on a transaction-by-transaction basis. A system, such as 
an RFQ system, that is designed to provide the ability of more than one 
buyer to request quotes from more than one seller in securities at the 
same or different times would meet the ``multiple'' prong of Rule 3b-
16(a) because such systems do not include a single counterparty.\104\ 
Because RFQ systems have more than one buyer and more than one seller, 
such systems do not have a single counterparty and thus

[[Page 15506]]

would meet the standard of ``multiple buyers and sellers'' under Rule 
3b-16(a)(1). Nevertheless, removing the term ``multiple'' would 
mitigate confusion and the potential to misconstrue the application of 
Rule 3b-16(a) to systems with non-firm trading interest, including RFQ 
systems, and aligns the rule with the statutory definition of 
``exchange.'' \105\
---------------------------------------------------------------------------

    \104\ The mere interpositioning of a designated counterparty to 
provide for the anonymity of counterparties to a trade or for 
settlement purposes after the purchasing and selling counterparties 
to a trade have been matched would not, by itself, mean the system 
does not have multiple buyers and sellers. See Regulation ATS 
Adopting Release, supra note 31, at 70849.
    \105\ The use of plural terms in ``buyers and sellers'' in Rule 
3b-16(a) and ``purchasers and sellers'' (emphasis added) in the 
statutory definition of ``exchange'' makes sufficiently clear that 
an exchange need only have more than one buyer and more than one 
seller participating on the system to meet this prong.
---------------------------------------------------------------------------

    The Commission is proposing to amend Rule 3b-16(b) to add an 
exclusion from Rule 3b-16(a) for systems that allow an issuer to sell 
its securities to investors. The Commission stated in the Regulation 
ATS Adopting Release that systems for issuers to sell their own 
securities would not fall within Rule 3b-16(a) because such systems 
have a single counterparty that is selling its securities.\106\ The 
Commission continues to believe that such systems do not meet the 
criteria of Rule 3b-16(a) because the systems do not bring together 
multiple buyers and multiple sellers. Given the proposal to remove the 
term ``multiple'' from Rule 3b-16(a)(1), adding the exclusion for 
issuer systems would clarify that such systems do not fall within the 
criteria of Rule 3b-16(a).
---------------------------------------------------------------------------

    \106\ See supra note 102 and accompanying text.
---------------------------------------------------------------------------

3. Established Methods; Communication Protocols
    The Commission is proposing to amend Rule 3b-16(a)(2) to replace 
``uses established, non-discretionary methods'' with the phrase ``makes 
available established, non-discretionary methods.'' The proposed change 
to use the word ``makes available'' rather than ``uses'' is designed to 
capture established, non-discretionary methods that an organization, 
association, or group of persons may provide, whether directly or 
indirectly, for buyers and sellers to interact and agree upon terms of 
a trade. In contrast to the term ``uses,'' the Commission believes the 
term ``makes available'' would be applicable to Communication Protocol 
Systems because such systems take a more passive role in providing to 
their participants the means and protocols to interact, negotiate, and 
come to an agreement.
    The term ``makes available'' is also intended to make clear that, 
in the event that a party other than the organization, association, or 
group of persons performs a function of the exchange, the function 
performed by that party would still be captured for purposes of 
determining the scope of the exchange under Exchange Act Rule 3b-16. In 
the Regulation ATS Adopting Release, the Commission stated that it will 
attribute the activities of a trading facility to a system if that 
facility is offered by the system directly or indirectly (such as where 
a system arranges for a third party or parties to offer the trading 
facility).\107\ The Commission has further recognized how a system may 
consist of various functionalities, mechanisms, or protocols that 
operate collectively to bring together the orders for securities of 
multiple buyers and sellers using non-discretionary methods under the 
criteria of Rule 3b-16(a), and how, in some circumstances, these 
various functionalities, mechanisms, or protocols may be offered or 
performed by another business unit of the registered broker-dealer or 
government securities broker or government securities dealer that 
operates the ATS (``broker-dealer operator'') or by a separate 
entity.\108\ These principles equally apply to an organization, 
association, or group of persons that arranges with another party to 
provide, for example, a trading facility or communication protocols, or 
parts thereof, to bring together buyers and sellers and perform a 
function of a system under Rule 3b-16. Using the term ``makes 
available'' will help ensure that the investor protection and fair and 
orderly markets provisions of the exchange regulatory framework apply 
to all the activities that consist of the system that meets the 
criteria of Rule 3b-16(a), notwithstanding whether those activities are 
performed by a party other than the organization that is providing the 
market place.\109\

70852.
    \108\ See NMS Stock ATS Adopting Release, supra note 2, at 38844 
(citing Regulation ATS Adopting Release, 63 FR 70852).
    \109\ Depending on the activities of the persons involved with 
the market place, a group of persons, who may each perform a part of 
the 3b-16 system, can together provide, constitute, or maintain a 
market place or facilities for bringing together purchasers and 
sellers of securities and together meet the definition of exchange. 
In such a case, the group of persons would have the regulatory 
responsibility for the exchange.

    The Commission is not proposing to delete the term ``non-
discretionary'' from Rule 3b-16(a)(2). The term ``non-discretionary'' 
was added to Rule 3b-16(a)(2) to modify ``methods'' to distinguish the 
activities of an exchange from the activities of a broker-dealer.\110\ 
As discussed in the Regulation ATS Adopting Release, broker-dealers 
exercise control, judgement, or discretion over their customers' orders 
or trading interests \111\ while an exchange operates pursuant to 
programmed procedures or set rules and does not exercise discretion 
over orders or trading interest entered into the system.\112\ The 
Commission continues to believe that the distinction between an 
exchange and a broker-dealer explained in the Regulation ATS Adopting 
Release is appropriate and the Commission is not proposing to amend 
Exchange Act Rule 3b-16(a) to include activities of broker-dealers 
within the definition of ``exchange.'' \113\
---------------------------------------------------------------------------

    \110\ See Regulation ATS Adopting Release, supra note 31, at 
70863.
    \111\ See id. at 70851.
    \112\ See id. at 70850.
    \113\ If a system meets the criteria of Exchange Act Rule 3b-
16(a) but includes in that system the ability of the system operator 
to apply its discretion for handling trading interest, these 
activities employing discretion by the system operator would be 
included in the system that meets the criteria of Rule 3b-16(a) and 
be subject to Federal securities laws and rules applicable to a 
registered exchange or ATS (including, for example, requirements to 
provide disclosures about the system operator's activities on Form 
ATS or ATS-N and, if the ATS is subject to the Fair Access Rule, 
include in its written standards why the activities of the system 
operator that result in the different treatment of subscribers are 
fair and not unreasonably discriminatory).
---------------------------------------------------------------------------

    The term ``non-discretionary'' should not be misconstrued to mean 
that a system does not meet the definition of exchange if it permits 
buyers or sellers using the system to exercise discretion with regard 
to the use of the system. Under current Rule 3b-16(a)(2), the phrase 
``uses established, non-discretionary methods'' applies to the 
organization, association, or group of persons that provides the 
means--the trading facility or rules--under which orders interact. 
Thus, an organization that meets the definition of ``exchange'' does 
not exercise any discretion in the matching of buyers and sellers or 
their orders and buyers and sellers participating on an exchange can 
use their own discretion in finding and selecting a counterparty.\114\ 
The phrase

[[Page 15507]]

``established, non-discretionary methods'' continues to convey that the 
system provider is providing the trading facility or communication 
protocols or setting rules and is not applying its discretion in 
matching counterparties on the system.\115\
---------------------------------------------------------------------------

    \114\ One commenter on the 2020 Proposal and Concept Release 
stated their belief that ``unlike an ATS on which trading takes 
place on a non-discretionary basis, trading discretion is a defining 
feature of these protocols; a requesting participant can choose the 
number and identity of participants that will receive the RFQ, while 
participants who receive an RFQ can choose whether to respond.'' See 
ICI Letter at 7. See also Bloomberg Letter at 23 (describing that an 
RFQ ``consists of discretionary directed order communication network 
messaging'' and stating its belief that such messaging is not an ATS 
function because RFQs lack a non-discretionary commitment to trade) 
and MarketAxess Letter at n.2 (stating its belief that an RFQ 
trading requestor's trading discretion puts the protocol outside the 
requirement that the platform use ``established, non-discretionary 
methods under which such orders interact with each other''). The 
``established, non-discretionary methods'' element of Rule 3b-
16(a)(2) pertains to the discretion applied by the system provider 
to bring together buyers and sellers and not discretion that 
participants may apply. For example, a system provider that matches 
buyers and sellers using its judgement or discretion would not be 
using established, non-discretionary methods. As the Commission 
stated in the Regulation ATS Adopting Release, where customers of a 
broker-dealer exercise control over their own orders in a trading 
system operated by the broker-dealer, that broker-dealer is unlikely 
to be viewed as using discretionary methods in handling the order. 
See Regulation ATS Adopting Release, supra note 31, at 70851.
    \115\ See id. (describing that, for example, the Commission does 
not believe that block trading desks, which generally retain some 
discretion in determining how to execute a customer's order, and 
frequently commit capital to satisfy their customers' needs, use 
established, non-discretionary methods).
---------------------------------------------------------------------------

    The Commission is proposing to amend Rule 3b-16(a)(2) to add 
``communication protocols'' as an established method that an 
organization, association, or group of persons can provide to bring 
together buyers and sellers of securities. Systems that bring together 
buyers and sellers of securities may function as exchange market places 
of securities without orders or a trading facility for orders to 
interact. In the Commission's experience, communication protocols, 
which can be applied to various technologies and connectivity, 
generally use non-firm trading interest as opposed to orders to prompt 
and guide buyers and sellers to communicate, negotiate, and agree to 
the terms of the trade. For example, if an entity makes available a 
chat feature, which requires certain information to be included in a 
chat message (e.g., price, quantity) and sets parameters and structure 
designed for participants to communicate about buying or selling 
securities, the system would have established communication protocols.
    While Communication Protocol Systems may not match counterparties' 
trading interest, buyers and sellers using these can be brought 
together to interact, either on a bilateral or multilateral basis, and 
agree upon the terms of the trade. Protocols that a system offers may 
take many forms and could include: Setting minimum criteria for what 
messages must contain; setting time periods under which buyers and 
sellers must respond to messages; restricting the number of persons a 
message can be sent to; limiting the types of securities about which 
buyers and sellers can communicate; setting minimums on the size of the 
trading interest to be negotiated; or organizing the presentation of 
trading interest, whether firm or non-firm, to participants. These 
examples are not exhaustive, and the determination of whether the 
system meets Rule 3b-16(a)(2) would depend on the particular facts and 
circumstances of each system. Nevertheless, as proposed, the Commission 
would take an expansive view of what would constitute ``communication 
protocols'' under this prong of Rule 3b-16(a).\116\
---------------------------------------------------------------------------

    \116\ One commenter suggested a litmus test to assist the 
Commission in determining whether a fixed-income trading platform 
for corporate bonds and municipal securities meets the criteria that 
warrant registration as an exchange or ATS. According to the 
commenter, the most relevant criteria were: Whether the system 
provides multilateral trading, whether the technology provider has 
any influence on picking the counterparties, whether the system 
enables any sharing of real-time information across multiple 
counterparties, whether the system provider has any access to real-
time information, and whether the transactions happen on the 
technology platform. See letter from Vijay Kedia, President and CEO, 
FlexTrade Systems, dated March 1, 2021 (``FlexTrade Systems 
Letter'') at 2. As discussed above, the Commission believes that 
conditions have changed whereby systems that offer the use trading 
interest and protocols to bring together buyers and sellers of 
securities perform an exchange market place function similar to 
systems that offer the use of orders and trading facilities. As 
proposed, a Communication Protocol System can still meet the 
criteria of Exchange Act Rule 3b-16 even if it has no role in 
matching counterparties nor displays trading interest. In addition, 
neither the current rule nor the proposed amendments require that, 
for a system to be an exchange, an execution occur on the system; 
rather, that the buyers and sellers agree to the terms of the trade 
on the system is sufficient. See Regulation ATS Adopting Release, 
supra note 31, at 70852 (stating ``whether or not the actual 
execution of the order takes place on the system is not a 
determining factor of whether the system falls under Rule 3b-16''). 
Also, applying some of the criteria that the commenter suggested 
(whether system provider have any access to real-time information; 
whether the transactions happen on the technology platform) could 
result in the exclusion of certain RFQ platforms from the definition 
of exchange.
---------------------------------------------------------------------------

    The Commission preliminarily believes that certain systems would 
not fall within the criteria of Exchange Act Rule 3b-16(a), as proposed 
to be amended, because the organization, association, or group of 
persons would not be considered to be providing a trading facility or 
communication protocol and therefore would not be considered to be 
making available established, non-discretionary methods under Rule 3b-
16(a)(2).\117\ The Commission continues to believe that systems that 
passively display trading interest, such as systems referred to in the 
industry as bulletin boards, but do not provide means for buyers and 
sellers to contact each other and agree to the terms of the trade on 
the system would not be encompassed by Rule 3b-16(a) as proposed to be 
amended.\118\ For example, the Commission does not believe that a 
system that unilaterally displays trading interest without offering a 
trading facility or communication protocols to bring together buyers 
and sellers would be considered to be making available established, 
non-discretionary methods.\119\ In the Regulation ATS Adopting Release, 
the Commission stated that ``[u]nless a system also establishes rules 
and operates a trading facility under which subscribers can agree to 
the terms of their trades, the system will not be included within Rule 
3b-16 even if it brings together `orders.' '' \120\ These systems may 
display trading interest to potential buyers and sellers, but the 
system provider is not making available established methods for buyers 
and sellers to interact and agree upon terms of a trade. If adopted, 
however, the Commission would continue to monitor market developments 
to ascertain whether such systems may warrant further regulation in the 
future.
---------------------------------------------------------------------------

    \117\ To the extent that a system is currently operating 
consistently with the circumstances described in a staff no-action 
letter, a system that falls within the scope of Rule 3b-16(a) and 
seeks to rely on the ATS exemption would need to register as a 
broker-dealer to comply with the broker-dealer registration 
requirement under Regulation ATS, regardless of any prior staff 
statement. Upon the adoption of any final rule, some letters and 
other staff statements, or portions thereof, may be moot, 
superseded, or otherwise inconsistent with the final rule and, 
therefore, would be withdrawn or modified.
    \118\ See Regulation ATS Adopting Release, supra note 31, at 
70850. See also FINRA Letter at 9-10 (requesting the Commission 
provide additional guidance on the regulatory classification of 
bulletin boards).
    \119\ See SIFMA Letter at 11 (stating that systems that merely 
act as informational conduits should remain outside the scope of 
Regulation ATS); FlexTrade Systems Letter at 2-4 (stating that 
software vendors that provide functionality for displaying prices do 
not meet the definition of an exchange).
    \120\ See Regulation ATS Adopting Release, supra note 31, at 
70850.
---------------------------------------------------------------------------

    Similarly, a system that displays trading interest and provides 
only connectivity among participants without providing a trading 
facility to match orders or providing protocols for participants to 
communicate and interact would not meet the criteria of Rule 3b-16(a) 
because such system would not be considered to be making available 
established, non-discretionary methods. For example, systems that only 
provide general connectivity for persons to communicate without 
protocols, such as utilities or electronic web chat providers, would 
not fall within the communication protocols prong of the proposed rule 
because such providers are not specifically designed

[[Page 15508]]

to bring together buyers and seller of securities or provide procedures 
or parameters for buyers and sellers for securities to interact. To the 
extent that such systems are designed for securities and provide 
communication protocols for buyers and sellers to interact and agree to 
the terms of a trade, such systems would fall within the criteria of 
Exchange Act Rule 3b-16(a) as proposed to be revised.

D. Exchange Registration or ATS Exemption for Communication Protocol 
Systems Under the Proposed Rules

    The proposed amendments to Exchange Act Rule 3b-16(a) would scope 
Communication Protocol Systems into the definition of ``exchange,'' in 
which case, the systems may decide between registering as a national 
securities exchange or registering as a broker-dealer and complying 
with Regulation ATS. The Commission believes that many Communication 
Protocol Systems would likely choose to be regulated as an ATS because 
of the lighter regulatory requirements imposed on them, as compared to 
the regulatory requirements of registered exchanges, which are SROs. 
Unlike a national securities exchange, an ATS can trade any type of 
security and its users are not limited to broker-dealers. In addition, 
an ATS is not an SRO, is not subject to Section 6 of the Exchange Act, 
and does not require Commission approval for its activities. Complying 
with Regulation ATS would therefore allow Communication Protocol 
Systems more flexibility in the operation of their business than 
registering as an exchange.\121\
---------------------------------------------------------------------------

    \121\ ATSs have more flexibility in the operation of their 
business than exchanges insofar as ATSs are not subject to Section 6 
of the Exchange Act and are not required to comply with the 
statutory standards with respect to unfair discrimination, burdens 
on competition, and the equitable allocation of reasonable fees.
---------------------------------------------------------------------------

    Further, many Communication Protocol Systems make available for 
trading fixed income securities that are only traded over-the-counter 
and are not typically registered and approved for listing on an 
exchange.\122\ Unless a national securities exchange receives an 
exemption to trade unregistered debt securities,\123\ it may only list 
and trade registered debt securities, whereas Communication Protocol 
Systems need not receive such an exemption to trade unregistered debt 
securities. Notwithstanding, the Commission discusses the regulatory 
requirements for both regulatory alternatives below. The Commission is 
not proposing to make changes to the regulatory structure for exchanges 
or the requirements for national securities exchanges. The proposed 
changes to the regulatory requirements under Regulation ATS are 
discussed in more detail below.\124\
---------------------------------------------------------------------------

    \122\ Section 12(a) of the Exchange Act makes it unlawful for 
any member, broker, or dealer to effect any transaction in any 
security (other than an exempted security) on a national securities 
exchange unless a registration statement has been filed with the 
Commission and is in effect as to such security for such exchange in 
accordance with the provisions of the Exchange Act and the rules and 
regulations thereunder. 15 U.S.C. 78l(a). Section 12(b) of the 
Exchange Act, 15 U.S.C. 78l(b), contains procedures for the 
registration of securities on a national securities exchange. 
Section 12(a) does not apply to an exchange that the Commission has 
exempted from registration as a national securities exchange. See, 
e.g., Securities Exchange Act Release No. 28899 (February 20, 1991), 
56 FR 8377 (February 29, 1991). See also Regulation ATS Adopting 
Release, supra note 31, at 70886.
    \123\ See, e.g., Securities Exchange Act Release No. 54767 
(November 16, 2006), 71 FR 67680 (November 22, 2006) (SR-NYSE-2004-
69) (issuing exemption permitting NYSE to trade unregistered debt 
securities on its bonds platform, now known as NYSE Bonds).
    \124\ See infra Section III.B.2 (discussing proposed changes to 
Rule 301(b)(1) of Regulation ATS), Section IV (discussing proposed 
changes to Rule 304 and Form ATS-N), Section V.A (discussing 
proposed changes to Rule 301(b)(5) and 301(b)(6)), and Section V.C 
(discussing proposed changes to Rule 301(b)(2)(vii)).
---------------------------------------------------------------------------

1. National Securities Exchange Registration
    A Communication Protocol System that chooses to register as a 
national securities exchange would be required to do so pursuant to 
Sections 5 and 6 of the Exchange Act. A national securities exchange is 
an SRO and must set standards of conduct for its members, administer 
examinations for compliance with these standards, coordinate with other 
SROs with respect to the dissemination of consolidated market data, and 
generally take responsibility for enforcing its own rules and the 
provisions of the Exchange Act and the rules and regulations 
thereunder. Before a national securities exchange may commence 
operations, the Commission must approve its application for 
registration filed on Form 1.\125\ Section 6(b) of the Exchange Act 
requires, among other things, that the national securities exchange be 
so organized and have the capacity to carry out the purposes of the 
Exchange Act and to comply and enforce compliance by its members, and 
persons associated with its members, with the Federal securities laws 
and the rules of the exchange.\126\ Pursuant to Section 6 of the 
Exchange Act, national securities exchanges must establish rules that 
generally: (1) Are designed to prevent fraud and manipulation, promote 
just and equitable principles of trade, and protect investors and the 
public interest; (2) provide for the equitable allocation of reasonable 
fees; (3) do not permit unfair discrimination; (4) do not impose any 
unnecessary or inappropriate burden on competition; and (5) with 
limited exceptions, allow any broker-dealer to become a member.\127\
---------------------------------------------------------------------------

    \125\ See 15 U.S.C. 78f.
    \126\ See Section 6(b)(1) of the Exchange Act, 15 U.S.C. 
78f(b)(1). The Commission must also find that the national 
securities exchange has rules that meet certain criteria. See 
generally Exchange Act Section 6(b)(2) through (10), 15 U.S.C. 
78f(b)(2) through (10).
    \127\ See Section 6(b) of the Exchange Act.
---------------------------------------------------------------------------

    After approval of its application for registration, a national 
securities exchange must file with the Commission any proposed changes 
to its rules.\128\ The initial application on Form 1, amendments 
thereto, and filings for proposed rule changes, in combination, 
publicly disclose important information about national securities 
exchanges, such as trading services and fees. The Commission's order 
approving the application is also public. The Commission oversees the 
exchanges under the Exchange Act through, among other things, its 
examination authority under Section 17, its enforcement authority under 
Sections 19(h)(1) and 21C, its authority to approve and disapprove 
rules under Section 19(b), and its rulemaking authority under various 
Exchange Act provisions. Under the Exchange Act, securities traded on a 
national securities exchange must be registered with the Commission and 
approved for listing on an exchange. National securities exchanges can 
only have broker-dealer members. As an SRO, a national securities 
exchange enjoys certain unique benefits, such as limited immunity from 
private liability with respect to its regulatory functions and the 
ability to receive consolidated revenue under the national market 
system plans for equity market data (i.e., Consolidated Tape 
Association (CTA)/Consolidated Quotation (CQ) and Unlisted Trading 
Privilege (UTP)),\129\ among others.
---------------------------------------------------------------------------

    \128\ See generally Section 19(b) of the Exchange Act, 15 U.S.C. 
78s(b).

<a href="https://www.ctaplan.com/plans">https://www.ctaplan.com/plans</a>; and <a href="https://www.utpplan.com">https://www.utpplan.com</a>.
---------------------------------------------------------------------------

2. Regulation ATS Exemption; Broker-Dealer Registration
    A Communication Protocol System may choose to operate as an ATS 
pursuant to Regulation ATS, which exempts an ATS from the definition of 
``exchange'' on the condition that the ATS is in compliance with the 
requirements of Regulation ATS. An ATS that fails to comply with the 
requirements of Regulation ATS would

[[Page 15509]]

no longer qualify for the ATS exemption and thus risks operating as an 
unregistered exchange in violation of Section 5 of the Exchange Act.
    To operate under the exemption, an ATS must register as a broker-
dealer under Exchange Act Section 15 or as a government securities 
broker or government securities dealer under Exchange Act Section 
15C(a)(1)(A),\130\ and comply with the filing and conduct obligations 
associated with being a registered broker-dealer, including membership 
in an SRO, such as FINRA,\131\ and compliance with the SRO's 
rules.\132\ Requiring Communication Protocol Systems to register as 
broker-dealers and be a member of an SRO would ensure that they are 
subject to SRO examination and market surveillance, trade reporting 
obligations, and certain investor protection rules. Broker-dealer 
registration provides important investor protections under the Federal 
securities laws and FINRA rules, such as: (1) Various disclosure and 
supervision obligations; (2) anti-money laundering obligations 
(including suspicious activity reporting); (3) FINRA over-the-counter 
(OTC) trade reporting requirements, including requirements to maintain 
membership in, or maintain an effective clearing arrangement with a 
participant of, a clearing agency registered under the Exchange Act; 
and (4) Commission examinations and FINRA examinations and surveillance 
of members and markets that its members operate.
---------------------------------------------------------------------------

    \130\ The Commission is proposing to amend Rule 301(b)(1) to 
allow an ATS to register as a government securities broker or 
government securities dealer under Exchange Act Section 
15C(a)(1)(A). See infra notes 272-278 and accompanying text.
    \131\ See Section 15(b)(8) of the Exchange Act; 15 U.S.C. 
78o(b)(8).
    \132\ See Regulation ATS Adopting Release, supra note 31, at 
70903.
---------------------------------------------------------------------------

    In addition, ATSs are subject to certain reporting and disclosure 
requirements, as applicable. ATSs other than NMS Stock ATSs or, as 
proposed, Government Securities ATSs, would be required, pursuant to 
Rule 301(b)(2) of Regulation ATS, to file an initial operation report 
with the Commission on Form ATS \133\ at least 20 days before 
commencing operations or, in the case of Newly Designated ATSs,\134\ no 
later than 30 calendar days after the effective date of any final 
rule.\135\ Form ATS provides the Commission with the opportunity to 
identify problems that might impact investors before the system begins 
to operate.\136\ Unlike a Form 1 filed by a national securities 
exchange, a Form ATS is not approved by the Commission.\137\ Also 
unlike a Form 1 application, a Form ATS is deemed confidential when 
filed.\138\ Requiring Communication Protocol Systems to file Form ATS 
and amendments thereto will help the Commission monitor and oversee 
such ATSs' operations.
---------------------------------------------------------------------------

    \133\ Form ATS and the Form ATS Instructions are available at 
<a href="https://www.sec.gov/about/forms/formats.pdf">https://www.sec.gov/about/forms/formats.pdf</a>. Form ATS would require, 
among other things, that the ATS (other than a Government Securities 
ATS or NMS Stock ATS) provide information about: Classes of 
subscribers and differences in access to the services offered by the 
ATS to different groups or classes of subscribers; securities the 
ATS expects to trade; any entity other than the ATS involved in its 
operations; the manner in which the system operates; how subscribers 
access the trading system; procedures governing entry of trading 
interest and execution; and trade reporting, clearance and 
settlement of trades on the ATS. See infra Section V.B (describing 
proposed changes to Form ATS). Regulation ATS provides that a report 
on Form ATS or Form ATS-R shall be considered filed upon receipt by 
the Division of Trading and Markets, at the Commission's principal 
office in Washington, DC (i.e., in paper form), and that information 
filed by an ATS on Form ATS is deemed confidential when filed. See 
17 CFR 242.301(b)(2)(vii). See also infra Section V.C.
    \134\ ``Newly Designated ATSs'' would be defined as ATSs 
operating as of the effective date of any final rule that meet the 
criteria under Rule 3b-16(a) as of the effective date of any final 
rule but did not meet the criteria under Rule 3b-16(a) in effect 
prior to the effective date of any final rule. See Rule 300(r).
    \135\ See infra note 180 and accompanying text. The Commission 
is also proposing changes to Rule 301(b)(2)(i) to clarify that the 
requirement to file Form ATS does not apply to Covered ATSs or 
Covered Newly Designated ATSs. See proposed Rule 301(b)(2)(i). See 
also proposed Rule 300(s) (defining ``Covered Newly Designated 
ATS'').
    \136\ See Regulation ATS Adopting Release, supra note 31, at 
70864.
    \137\ Form ATS provides the Commission with notice about an 
ATS's operations prior to commencing operations. An ATS is also 
required to notify the Commission of any changes in its operations 
by filing an amendment to its initial operation report. There are 
three types of amendments to an initial operation report. First, if 
any material change is made to its operations, the ATS must file an 
amendment on Form ATS at least 20 calendar days before implementing 
such change. See 17 CFR 242.301(b)(2)(ii). A ``material change,'' 
includes, but is not limited to, any change to the operating 
platform, the types of securities traded, or the types of 
subscribers. In addition, the Commission has stated that ATSs 
implicitly make materiality decisions in determining when to notify 
their subscribers of changes. See Regulation ATS Adopting Release, 
supra note 31, at 70864. Second, if any information contained in the 
initial operation report becomes inaccurate for any reason and has 
not been previously reported to the Commission as an amendment on 
Form ATS, the ATS must file an amendment on Form ATS correcting the 
information within 30 calendar days after the end of the calendar 
quarter in which the system has operated. See 17 CFR 
242.301(b)(2)(iii). Third, an ATS must promptly file an amendment on 
Form ATS correcting information that it previously reported on Form 
ATS after discovery that any information was inaccurate when filed. 
See 17 CFR 242.301(b)(2)(iv). An ATS is required to promptly file a 
cessation of operations on Form ATS. See 17 CFR 242.301(b)(2)(v).
    \138\ See 17 CFR 242.301(b)(2)(vii); Form ATS at 3, General 
Instructions A.7.
---------------------------------------------------------------------------

    NMS Stock ATSs and, as proposed, Government Securities ATSs, would 
be subject to enhanced filing and disclosure requirements under Rule 
304 of Regulation ATS. NMS Stock ATSs or Government Securities ATSs 
would, in lieu of Form ATS, be required to file public Form ATS-N in 
EDGAR, in which they must disclose detailed information about the 
manner in which their trading systems operate and the potential for 
conflicts of interest and information leakage.\139\ Form ATS-N is 
subject to a Commission review and effectiveness process.\140\ An NMS 
Stock ATS or Government Securities ATS would not be permitted to 
operate pursuant to the Rule 3a1-1(a)(2) exemption until its Form ATS-N 
has become effective.\141\ In addition, the ATS would be required to 
file amendments on Form ATS-N to provide notice of changes to its 
operations and broker-dealer and affiliate relationships.\142\ Form 
ATS-N and the Commission review and effectiveness process, which is 
described in detail below,\143\ would provide operational transparency 
and regulatory oversight of Communication Protocol Systems that are NMS 
Stock ATSs or Government Securities ATSs.
---------------------------------------------------------------------------

    \139\ See proposed changes to 17 CFR 242.304.
    \140\ See infra Section IV.A.
    \141\ See Rule 304(a)(1)(i).
    \142\ See infra Section IV.A.
    \143\ See infra Section IV.
---------------------------------------------------------------------------

    In addition, all ATSs are required to periodically, by paper 
submission, report certain information about transactions in the ATS 
and information about certain activities on Form ATS-R within 30 
calendar days after the end of each calendar quarter in which the 
market has operated, pursuant to Rule 301(b)(9).\144\ Form ATS-R 
requires quarterly volume information for specified categories of 
securities, as well as a list of all securities traded in the ATS 
during the quarter and a list of all subscribers that were participants 
during the quarter,\145\ and for ATSs subject to the Fair Access Rule 
to provide certain additional

[[Page 15510]]

information.\146\ Like Form ATS, Rule 301(b)(2)(vii) and the 
instructions to Form ATS-R provide that Form ATS-R is deemed 
confidential when filed.\147\ The information reported on Form ATS-R by 
Communication Protocol Systems would permit the Commission to monitor 
the trading on these ATSs for compliance with the Exchange Act and 
applicable rules thereunder and enforce the Fair Access Rule.\148\
---------------------------------------------------------------------------

    \144\ See 17 CFR 242.301(b)(9)(i). Form ATS-R and the Form ATS-R 
Instructions are available at <a href="https://www.sec.gov/about/forms/formats-r.pdf">https://www.sec.gov/about/forms/formats-r.pdf</a>. See also Section V.B (describing proposed changes to 
Form ATS-R).
    \145\ See Form ATS-R at 4, Items 1 and 2 (describing the 
requirements for Exhibit A and Exhibit B of Form ATS-R). ATSs must 
also complete and file Form ATS-R within 10 calendar days after 
ceasing to operate. See 17 CFR 242.301(b)(9)(ii); Form ATS-R at 2, 
General Instructions A.2 to Form ATS-R.
    \146\ Form ATS-R also requires an ATS that is subject to the 
fair access obligations under Rule 301(b)(5) of Regulation ATS to 
provide a list of all persons granted, denied, or limited access to 
the ATS during the period covered by the ATS-R and designate for 
each person each of the following: Whether the person was granted, 
denied, or limited access; the date the ATS took such action; the 
effective date of such action; and the nature of any denial or 
limitation of access. See Form ATS-R at 6, Item 7 (explaining 
requirements for Exhibit C).
    \147\ See 17 CFR 242.301(b)(2)(vii); Form ATS-R at 2, General 
Instruction A.7.
    \148\ See Regulation ATS Adopting Release, supra note 31, at 
70874 and 70878.
---------------------------------------------------------------------------

    NMS Stock ATSs must comply with certain order display and execution 
access obligations \149\ under Rule 301(b)(3) if the ATS displays 
subscriber orders in an NMS stock to any person (other than an employee 
of the ATS) and meets certain volume requirements.\150\ These order 
display and execution access obligations were adopted by the Commission 
with the expectation they would promote additional market integration 
and further discourage two-tier markets when trading in an NMS stock on 
an ATS reaches a certain level.\151\ In addition, an NMS Stock ATS must 
not charge any fee to broker-dealers that access the ATS through a 
national securities exchange or national securities association that is 
inconsistent with the equivalent access to the NMS Stock ATS that is 
required under Rule 301(b)(3)(iii).\152\ This requirement is designed 
to promote equal access to ATSs.
---------------------------------------------------------------------------

    \149\ An ATS that displays orders and meets the volume 
requirements must provide to a national securities exchange or 
national securities association the prices and sizes of the orders 
at the highest buy price and the lowest sell price for such NMS 
stock, displayed to more than one person in the ATS, for inclusion 
in the quotation data made available by the national securities 
exchange or national securities association pursuant to Rule 602 
under Regulation NMS. See 17 CFR 242.301(b)(3)(ii). With respect to 
any such displayed order, the ATS must provide to any broker-dealer 
that has access to the national securities exchange or national 
securities association to which the ATS provides the prices and 
sizes of displayed orders pursuant to Rule 301(b)(3)(ii), the 
ability to effect a transaction with such orders that is equivalent 
to the ability of such broker-dealer to effect a transaction with 
other orders displayed on the exchange or by the association; and at 
the price of the highest priced buy order or lowest priced sell 
order displayed for the lesser of the cumulative size of such priced 
orders entered therein at such price, or the size of the execution 
sought by such broker-dealer. See 17 CFR 242.301(b)(3)(iii).
    \150\ An ATS that displays subscriber orders in an NMS stock 
must comply with Rule 301(b)(3) if, during at least four of the 
preceding six calendar months, it had an average daily trading 
volume of 5% or more of the aggregate average daily share volume for 
that NMS stock, as reported by an effective transaction reporting 
plan. See 17 CFR 242.301(b)(3)(i).
    \151\ See Regulation ATS Adopting Release, supra note 31, at 
70867.
    \152\ See 17 CFR 242.301(b)(4). In addition, if the national 
securities exchange or national securities association to which an 
ATS provides the prices and sizes of orders under Rules 
301(b)(3)(ii) and (iii) establishes rules designed to assure 
consistency with standards for access to quotations displayed on 
such national securities exchange, or the market operated by such 
national securities association, the ATS shall not charge any fee to 
members that is contrary to, that is not disclosed in the manner 
required by, or that is inconsistent with any standard of equivalent 
access established by such rules. See id.
---------------------------------------------------------------------------

    As discussed in more detail below,\153\ ATSs are required to comply 
with the Fair Access Rule \154\ under Rule 301(b)(5) if the ATS meets 
volume thresholds in NMS stocks, equity securities that are not NMS 
stocks and for which transactions are reported to an SRO, municipal 
securities, or corporate debt securities.\155\ The Commission is 
proposing to apply the requirements of the Fair Access Rule to trading 
of U.S. Treasury Securities and Agency Securities on ATSs.\156\
---------------------------------------------------------------------------

    \153\ See infra Section III.B.4 and Section V.A.
    \154\ An ATS subject to the Fair Access Rule, as proposed to be 
revised, must: Establish and apply reasonable written standards for 
granting, limiting, and denying access to the services of the ATS; 
make and keep records of all grants of access including, for all 
participants, the reasons for granting such access, and all denials 
or limitations of access and reasons, for each applicant and 
participant, for denying or limiting access; and report on Form ATS-
R a list of persons granted, denied, and limited access to the ATS. 
See infra Section V.A.
    \155\ See 17 CFR 242.301(b)(5).
    \156\ See infra Section III.B.4.
---------------------------------------------------------------------------

    Additionally, under Rule 301(b)(6) (``Capacity, Integrity, and 
Security Rule''), an ATS that trades only municipal securities or 
corporate fixed income debt with 20% or more of the average daily 
volume traded in the U.S. during at least four of the preceding six 
calendar months would be required to comply with capacity, integrity, 
and security standards \157\ with respect to those systems that support 
order entry, order routing, order execution, transaction reporting, and 
trade comparison.\158\ Information provided under the Capacity, 
Integrity, and Security Rule would enable the Commission staff to 
better understand the operation of certain Communication Protocol 
Systems and to identify potential problems and trends that may require 
attention.
---------------------------------------------------------------------------

    \157\ An ATS that meets the volume requirements must, with 
respect to those systems that support order entry, order routing, 
order execution, transaction reporting, and trade comparison, 
establish reasonable current and future capacity estimates; conduct 
periodic capacity stress tests of critical systems to determine such 
system's ability to process transactions in an accurate, timely, and 
efficient manner; develop and implement reasonable procedures to 
review and keep current its system development and testing 
methodology; review the vulnerability of its systems and data center 
computer operations to internal and external threats, physical 
hazards, and natural disasters; establish adequate contingency and 
disaster recovery plans; on an annual basis, perform an independent 
review, in accordance with established audit procedures and 
standards, of the ATS's controls for ensuring that the above 
requirements are met, and conduct a review by senior management of a 
report containing the recommendations and conclusions of the 
independent review; and promptly notify the Commission and its staff 
of material systems outages and significant systems changes. See 17 
CFR 242.301(b)(6)(ii).
    \158\ See 17 CFR 242.301(b)(6)(i).
---------------------------------------------------------------------------

    NMS Stock ATSs, ATSs that trade non-NMS equity securities that are 
reported to an SRO, and Government Securities ATSs that meet certain 
trading thresholds would be subject to Regulation SCI. Regulation SCI 
superseded and replaced Rule 301(b)(6) requirements with regard to ATSs 
that trade NMS stocks and non-NMS stocks.\159\ The Commission is 
proposing to apply Regulation SCI to Government Securities ATSs, as 
discussed below.\160\ Regulation SCI is designed to help address the 
technological vulnerabilities, and improve the Commission's oversight 
of the core technology of key entities.
---------------------------------------------------------------------------

    \159\ Regulation SCI does not apply to ATSs that trade only 
municipal securities or corporate debt securities. See infra notes 
351-356 and accompanying text. See also Regulation SCI Adopting 
Release, supra note 3, at 72262.
    \160\ See infra Section III.C.
---------------------------------------------------------------------------

    All ATSs, regardless of the volume traded on their systems, are 
required, pursuant to Rule 301(b)(7),\161\ to permit the examination 
and inspection of their premises, systems, and records, and cooperate 
with the examination, inspection, or investigation of subscribers, 
whether such examination is being conducted by the Commission or by an 
SRO of which such subscriber is a member. Because an ATS subscriber to 
whom the Commission's inspection authority may not extend could use the 
ATS to manipulate the market in a security, the requirement is designed 
to require that ATSs cooperate in all inspections, examinations, and 
investigations.
---------------------------------------------------------------------------

    \161\ See 17 CFR 242.301(b)(7).
---------------------------------------------------------------------------

    ATSs are also required, pursuant to Rule 301(b)(8),\162\ to make 
and keep current the records specified in Rule 302 of Regulation ATS 
\163\ and preserve

[[Page 15511]]

the records specified in 17 CFR 242.303.\164\ The Commission is 
proposing to amend Rule 302 of Regulation ATS to require recordkeeping 
related to ``trading interest.'' Rule 302 requires that an ATS shall 
make and keep certain records, which the rule enumerates. Communication 
Protocol Systems that choose to comply with Regulation ATS would be 
required to keep the records enumerated in Rule 302. The Commission is 
proposing to revise certain of these enumerated records that relate to 
``orders'' to require such records related to ``trading interest,'' 
which would include both firm orders and non-firm trading 
interest.\165\ This would include time-sequenced records of trading 
interest information in the ATS.\166\ The recordkeeping requirements 
would require Communication Protocol Systems to make and keep certain 
records for an audit trail of trading activity that would allow the 
Commission to detect and investigate potential market irregularities, 
examine whether the ATS is in compliance with Federal securities laws, 
and ensure investor protections.\167\
---------------------------------------------------------------------------

    \162\ See 17 CFR 242.301(b)(8).
    \163\ See 17 CFR 242.302. Rule 302 requires all ATSs to make and 
keep current certain records, including: A record of subscribers to 
the ATS; daily summaries of trading in the ATS; and time-sequenced 
records of order information in the ATS. See 17 CFR 242.302.
    \164\ See Rule 303 of Regulation ATS. In the Regulation ATS 
Adopting Release, the Commission stated that these requirements to 
make, keep, and preserve records are necessary to create a 
meaningful audit trail and to permit surveillance and examination to 
help ensure fair and orderly markets. See Regulation ATS Adopting 
Release, supra note 31, at 70877-78.
    \165\ See supra note 98 and accompanying text.
    \166\ Specifically, the Commission is proposing to revise Rule 
302(c)(1) (date and time (expressed in terms of hours, minutes, and 
seconds) that the trading interest was received); (c)(3) (the number 
of shares, or principal amount of bonds, to which the trading 
interest applies); (c)(5) (the designation of the trading interest 
as buy or sell trading interest); (c)(8) (any limit or stop price 
prescribed by the trading interest); (c)(9) (the date on which the 
trading interest expires and, if the time in force is less than one 
day, the time when the trading interest expires); (c)(10) (the time 
limit during which the trading interest is in force); (c)(11) (any 
instructions to modify or cancel the trading interest); (c)(12) (the 
type of account for which the trading interest is submitted); 
(c)(13) (date and time that the trading interest was executed); 
(c)(14) (price at which the trading interest is executed); and 
(c)(15) (size of the trading interest executed).
    \167\ See Regulation ATS Adopting Release, supra note 31, at 
70878.
---------------------------------------------------------------------------

    In addition, ATSs are required to establish adequate written 
safeguards and written procedures \168\ to protect confidential trading 
information and to separate ATS functions from other broker-dealer 
functions, including principal and customer trading pursuant to Rule 
301(b)(10).\169\ Furthermore, all ATSs must adopt and implement 
adequate written oversight procedures to ensure that the above written 
safeguards and procedures are followed.\170\ These requirements are 
designed to help prevent the potential for abuse of subscriber 
confidential trading information.\171\
---------------------------------------------------------------------------

    \168\ These written safeguards and written procedures must 
include: Limiting access to the confidential trading information of 
subscribers to those employees of the ATS who are operating the 
system or responsible for its compliance with these or any other 
applicable rules; and implementing standards controlling employees 
of the ATS trading for their own accounts.
    \169\ See 17 CFR 242.301(b)(10); NMS Stock ATS Adopting Release, 
supra note 2, Section VI.
    \170\ See 17 CFR 242.301(b)(10)(ii).
    \171\ See NMS Stock ATS Adopting Release, supra note 2, at 
38864.
---------------------------------------------------------------------------

    In addition, an ATS must not use in its name the word ``exchange,'' 
or any derivation of the word ``exchange'' pursuant to Rule 
301(b)(11).\172\ The Commission believes that the use of the word 
``exchange'' by an ATS would be deceptive and could lead investors to 
believe incorrectly that such ATS is registered as a national 
securities exchange.\173\
---------------------------------------------------------------------------

    \172\ See 17 CFR 242.301(b)(11); Regulation ATS Adopting 
Release, supra note 31, Section II.C.
    \173\ See Securities Exchange Act Release No. 39884 (April 17, 
1998), 63 FR 23504, 23523 (April 29, 1998) (``Regulation ATS 
Proposing Release'').
---------------------------------------------------------------------------

    The Commission is proposing amendments to facilitate an orderly 
transition for Communication Protocol Systems to comply with the 
applicable conditions of the Regulation ATS exemption.\174\ The 
Commission understands that some Communication Protocol Systems are not 
currently registered as broker-dealers.\175\ To become a registered 
broker-dealer, these Communication Protocol Systems would be required 
to file Form BD with the Commission and complete FINRA's processes for 
new members.\176\ The Commission is proposing to allow Communication 
Protocol Systems that are not registered as broker-dealers at the time 
the proposed rule would be effective, if adopted, to provisionally 
operate pursuant to the Rule 3a1-1(a)(2) exemption while their broker-
dealer registration is pending until the earlier of (1) the date the 
ATS registers as a broker-dealer under Section 15 of the Exchange Act 
or Section 15C(a)(1)(A) of the Exchange Act and becomes a member of a 
national securities association or (2) the date 210 calendar days after 
the effective date of any final rule.\177\ The 210 calendar day period 
is designed to provide time for a Communication Protocol System to 
submit its broker-dealer registration application, or continuing 
membership application, as applicable, and for FINRA to conduct its 
review of new member application and continuing member application. The 
proposed transition period is designed to provide a Communication 
Protocol System that is not a registered broker-dealer adequate time to 
comply with the necessary broker-dealer registration requirements under 
Regulation ATS without disrupting its market or its participants.
---------------------------------------------------------------------------

    \174\ For purposes of the rule text, the Commission is proposing 
to apply the transitional rules to ``Newly Designated ATSs.''
    \175\ A registered broker-dealer that operates a Communication 
Protocol System and is currently a FINRA member may, under FINRA 
rules, be required to file a Continuing Membership Application with 
FINRA noticing material changes to business operations in connection 
with its operation of an ATS.
    \176\ After receiving a substantially complete application 
package, FINRA must review and process it within 180 calendar days. 
See ``How to Become a Member--Member Application Time Frames'' 
available at <a href="https://www.finra.org/registration-exams-ce/broker-dealers/how-become-member-membership-application-time-frames">https://www.finra.org/registration-exams-ce/broker-dealers/how-become-member-membership-application-time-frames</a>. See 
also FINRA Rule 1014.
    \177\ See proposed revisions to Rule 301(b)(1). This transition 
period for the proposed rule, if adopted, would also apply to 
Currently Exempted Government Securities ATSs (i.e., Legacy 
Government Securities ATSs formerly not required to comply with 
Regulation ATS pursuant to the exemption under Sec.  240.3a1-1(a)(3) 
prior to effective date of any final rule) not registered as a 
broker-dealer. See infra note 283.
---------------------------------------------------------------------------

    Proposed Rule 301(b)(2)(i) requires ATSs (other than Covered ATSs) 
\178\ to file an initial operation report on Form ATS at least 20 days 
before commencing operations; however, Communication Protocol Systems 
that seek to operate as ATSs already will be operating when the 
proposed rule, if adopted, becomes effective. To avoid disruption of 
the services of the ATS, the Commission is proposing to amend Rule 
301(b)(2)(i) to require Communication Protocol Systems (other than 
those that are Covered ATSs) \179\ to file an initial operation report 
on Form ATS no later than 30 calendar days after the effective date of 
any final rule.\180\ The Commission is also proposing changes, as 
discussed below, to Rule 301(b)(2)(viii) and Rule 304 to facilitate the 
transition for Communication Protocol Systems that are Covered ATSs to 
file Form ATS-N.\181\ Requiring Communication Protocol Systems to file 
a Form ATS with the Commission at the proposed time would provide the 
Commission with information about its

[[Page 15512]]

operations and facilitate oversight of the systems.
---------------------------------------------------------------------------

    \178\ ``Covered ATS'' is defined infra note 257. The Commission 
is proposing changes to Rule 301(b)(2)(i) to clarify that the 
requirement to file Form ATS does not apply to ATSs other than 
Covered ATSs. See proposed Rule 301(b)(2)(i).
    \179\ The rule text uses the term ``Covered Newly Designated 
ATS.''
    \180\ See proposed changes to Rule 301(b)(2)(i).
    \181\ See infra note 300 and Section IV.A.
---------------------------------------------------------------------------

Request for Comment
    1. Should the Commission amend Exchange Act Rule 3b-16 as proposed? 
Should the Commission adopt a more expansive or limited interpretation 
of the definition of ``exchange''? Do commenters agree that, in the 
current market, Communication Protocol Systems function as market 
places that conduct similar activities as exchanges do? Would any 
systems that conduct similar activities as exchanges that should be 
included in proposed Rule 3b-16 be excluded? Are there any asset 
classes or types of securities that should be excluded from the 
definition of exchange? If so, why?
    2. What are commenters' views on the potential consequences of 
expanding or limiting the definition of ``exchange'' under Exchange Act 
Rule 3b-16? What are commenters' views on how changing Rule 3b-16 could 
benefit or harm investors and market participants? Are new systems that 
meet the definition of exchange likely to choose to operate as ATSs 
instead of national securities exchanges?
    3. Should the Commission adopt the proposed definition of ``trading 
interest'' under Exchange Act Rule 3b-16? Should the definition of 
``trading interest'' require attributes to be identified in addition to 
at least the security and either quantity, direction (buy or sell), or 
price? Alternatively, would only one of the security, quantity, 
direction (buy or sell), or price be adequate to indicate trading 
interest? Should the definition of ``exchange'' continue to be limited 
to systems that use orders? If so, why?
    4. Should the Commission revise Exchange Act Rule 3b-16 to focus on 
bringing together buyers and sellers, rather than bringing together 
orders (or trading interest)? Would the proposed revisions to the rule 
appropriately describe systems that use non-firm trading interest to 
allow participants to communicate their trading interest?
    5. Should the Commission revise Exchange Act Rule 3b-16(a)(2) to 
describe a system that ``makes available established, non-discretionary 
methods'' under which buyers and sellers interact? Should the 
Commission revise the language further to clarify that a system 
provider that makes available a trading facility or communication 
protocol by way of a third party or affiliate would fall within the 
criteria of Rule 3b-16(a)(2)? Should there be any minimum or baseline 
to the established methods a system must have to qualify as an 
exchange? If so, what are they? Do commenters agree that making 
available communication protocols, as discussed herein, is sufficient 
to be an established, non-discretionary method under which buyers and 
sellers can interact?
    6. Should the Commission remove the reference to ``multiple'' in 
Rule 3b-16(a)(1))? If so, why? If not, why not?
    7. Should Communication Protocol Systems that choose to comply with 
Regulation ATS be subject to all of the requirements of Regulation ATS? 
Are there certain requirements of Regulation ATS that should or should 
not be applicable to Communication Protocol Systems, or certain 
Communication Protocol Systems? For example, are the current Regulation 
ATS recordkeeping requirements appropriate for Communication Protocol 
Systems? Should the Commission require a Communication Protocol System 
that chooses to operate as an ATS to create and maintain records that 
are not otherwise required by Rule 301(b)(8) of Regulation ATS? Is 
there anything that is not currently among the conditions to the 
Regulation ATS exemption that a Communication Protocol System and/or an 
existing ATS should comply with as part of Regulation ATS? And if so, 
why?
    8. Should the Commission amend Regulation ATS, Form ATS, Form ATS-
R, or Form ATS-N in any way to be more tailored to Communication 
Protocol Systems? If so, how?
    9. Are the proposed transition periods for Communication Protocol 
Systems appropriate? Should the Commission provide Communication 
Protocol Systems more or less time to comply with any of the 
requirements of Regulation ATS? Please explain.
    10. Is the Commission's proposal that a Newly Designated ATS must 
file an initial operation report on Form ATS no later than 30 calendar 
days after the effective date of any final rule, if adopted, 
appropriate? If not, should the Commission provide more time or less 
time for a Newly Designated ATS to file an initial Form ATS?
    11. Should the Commission allow a Newly Designated ATS that is not 
registered as a broker-dealer to operate pursuant to the Rule 3a1-
1(a)(2) exemption on a provisional basis? Does the proposal to allow 
such ATSs a maximum 210 calendar days to comply with the broker-dealer 
registration requirement provide an appropriate amount of time to 
register as a broker-dealer? If not, what, if any, transition period 
would be appropriate and why?

III. Proposed Changes Applicable to Government Securities ATSs

A. ATS Markets for Government Securities

    Government securities \182\ play a critical role in the U.S. and 
global economies. Among other things, for example, Treasury rates are a 
fundamental benchmark for pricing virtually all other financial 
assets.\183\ Systems currently operating as ATSs, particularly those 
that operate in the secondary interdealer markets for the most-recently 
issued (``on-the-run'') U.S. Treasury Securities, have become a 
significant location of trading interest for government 
securities.\184\ Specifically, most interdealer trading takes place on 
electronic platforms provided by interdealer brokers that operate limit 
order books, with electronic interdealer trading being

[[Page 15513]]

concentrated in on-the-run Treasury securities.\185\ In July 2021, 
average daily trading in government securities totaled $978 billion, or 
roughly 95 percent of all fixed income trading volume in the U.S.\186\
---------------------------------------------------------------------------

    \182\ Under the Exchange Act, government securities are defined 
as, among other things, securities which are direct obligations of, 
or obligations guaranteed as to principal or interest by, the United 
States. See 15 U.S.C. 78c(42)(A). Government securities include U.S. 
Treasury securities, debt securities issued or guaranteed by a U.S. 
executive agency, as defined in 5 U.S.C. 105, or government-
sponsored enterprise, as defined in 2 U.S.C. 622(8), and Agency 
Mortgage-Backed Securities (``MBSs''). Government securities also 
include securities which are issued or guaranteed by the Tennessee 
Valley Authority or by corporations in which the United States has a 
direct or indirect interest and which are designated by the 
Secretary of the Treasury for exemption as necessary or appropriate 
in the public interest or for the protection of investors; 
securities issued or guaranteed as to principal or interest by any 
corporation the securities of which are designated, by statute 
specifically naming such corporation, to constitute exempt 
securities within the meaning of the laws administered by the 
Commission; and any put, call, straddle, option, or privilege on one 
of the aforementioned (subject to limited exceptions). 15 U.S.C. 
78c(42)(B)-(C).

(``November 2021 IAWG Report''). The November 2021 IAWG Report is a 
joint report issued by the Inter-Agency Working Group for Treasury 
Market Surveillance (``IAWG''), which consists of staff from the 
U.S. Department of the Treasury, the Board of Governors of the 
Federal Reserve System, the Federal Reserve Bank of New York, the 
Commission, and the Commodity Futures Trading Commission. Among 
other things, the November 2021 IAWG report provides an overview of 
the current structure of the Treasury market and a detailed analysis 
of the recent disruptions to the Treasury market at the onset of the 
COVID-19 pandemic in March 2020 as well as other recent disruptions 
to the Treasury market. The report also sets forth what the IAWG 
believes are the six guiding principles for the Treasury market and 
provides an update about the work streams for specific policy 
analysis being undertaken by the members of the IAWG.

Backed Securities, and Federal Agency Securities.
---------------------------------------------------------------------------

    Legacy Government Securities ATSs now operate with complexity 
similar to that of markets that trade NMS stocks in terms of use of 
technology and speed of trading, the use of limit order books, order 
types, algorithms, connectivity, data feeds, and the active 
participation of principal trading firms (``PTFs'').\187\ For example, 
based on the Commission's review of Form ATS filings by ATSs that trade 
government securities and discussions with market participants, the 
Commission believes that Legacy Government Securities ATSs often offer 
subscribers a variety of order types to pursue both aggressive and 
passive trading strategies and low latency, high-speed connectivity to 
the ATS. These ATSs frequently use automated systems to match orders 
anonymously on a price/time priority basis. Some Legacy Government 
Securities ATSs also segment orders into categories by participants or 
allow participants the ability to interact with specific counterparty 
groups in the ATS and facilitate order interaction and execution.\188\ 
Likewise, Communication Protocol Systems are increasingly used as 
electronic means to bring together buyers and sellers for government 
securities and are particularly prevalent in the dealer-to-customer 
market for U.S. Treasury and markets for off-the-run \189\ U.S. 
Treasury Securities, Agency Securities,\190\ and repos.

    \190\ See James Collin Harkrader and Michael Puglia, Fixed 
Income Market Structure: Treasuries vs. Agency MBS, Board of 
Governors of the Federal Reserve System: FEDS NOTES (August 25, 
2020), available at <a href="https://www.federalreserve.gov/econres/notes/feds-notes/fixed-income-market-structure-treasuries-vs-agency-mbs-20200825.htm">https://www.federalreserve.gov/econres/notes/feds-notes/fixed-income-market-structure-treasuries-vs-agency-mbs-20200825.htm</a> (``August 25th FEDS Notes'') (explaining the recent 
evolution of the government securities market structure).
---------------------------------------------------------------------------

    The most liquid and commonly traded government securities are U.S. 
Treasury Securities, which are direct obligations of the U.S. 
Government issued by the U.S. Department of the Treasury (``Treasury 
Department''). The Treasury Department issues several different types 
of securities, including Treasury bills, nominal coupons notes and 
bonds, Floating Rate Notes, and Treasury Inflation Protected 
Securities. Treasury nominal coupon notes and bonds, as well as 
Treasury Inflation Protected Securities, may also be separated into 
principal and interest payments and traded as STRIPS.\191\ For each 
security type, the on-the-run securities are generally considered the 
most liquid in the secondary market.\192\ Market participants commonly 
refer to securities issued prior to ``on-the-run'' securities as ``off-
the-run'' securities.\193\ Market participants use U.S. Treasury 
Securities as an investment instrument, hedging vehicle, and to source 
orders and trading interest, among other things. U.S. banks commonly 
own U.S. Treasury Securities due to their low risk and strong liquidity 
characteristics. Additionally, U.S. Treasury Securities are often used 
as collateral in lending arrangements or as margin on other financial 
transactions.
---------------------------------------------------------------------------

    \191\ STRIPS is the acronym for Separate Trading of Registered 
Interest and Principal of Securities. STRIPS let investors hold and 
trade the individual interest and principal components of eligible 
Treasury notes and bonds as separate securities. STRIPS are Treasury 
securities that don't make periodic interest payments. Market 
participants create STRIPS by separating the interest and principal 
parts of a Treasury note or bond. STRIPS can only be bought and sold 
through a financial institution, broker, or dealer and held in the 
commercial book-entry system. See TreasuryDirect, STRIPS, available 
at <a href="https://www.treasurydirect.gov/instit/marketables/strips/strips.htm">https://www.treasurydirect.gov/instit/marketables/strips/strips.htm</a>.
    \192\ On-the-run U.S. Treasury Securities are the most recently 
issued nominal coupon securities. Nominal coupon securities pay a 
fixed semi-annual coupon and are currently issued at original 
maturities of 2, 3, 5, 7, 10, 20, and 30 years. These standard 
maturities are commonly referred to as ``benchmark'' securities 
because the yields for these securities are used as references to 
price a number of private market transactions.
    \193\ Off-the-run or ``seasoned'' U.S. Treasury Securities are 
the issues that preceded the current on-the-run securities. The U.S. 
Treasury Securities market also comprises futures and options on 
U.S. Treasury Securities, and securities financing transactions in 
which U.S. Treasury Securities are used as collateral. See Treasury 
Request for Information, supra note 188, at 3928. For the purpose of 
this proposal, the Commission focuses on the secondary cash market.
---------------------------------------------------------------------------

    For U.S. Treasury Securities, the secondary market is bifurcated 
between the dealer-to-customer market, in which dealers trade with 
their customers (e.g., investment companies, pension funds, insurance 
companies, corporations, or retail), and the interdealer market, in 
which dealers and specialty firms trade with one another.\194\ 
Customers, also referred to as ``end users,'' have not traditionally 
traded directly with other end users.\195\ Rather, end users primarily 
trade with dealers, and dealers use the interdealer market as a source 
of liquidity to help facilitate their trading with clients in the 
dealer-to-customer market. Trading in the U.S. Treasury Securities 
dealer-to-customer market is generally--and has historically been--
conducted bilaterally using voice, and more recently, electronically 
through the use of Communication Protocol Systems, most commonly using 
an RFQ protocol. Broker-dealers also internalize a portion of their 
customer flow, although the extent to which broker-dealers internalize 
is unclear.\196\
---------------------------------------------------------------------------

    \194\ See id.
    \195\ See id.
    \196\ See id. For the purposes of this proposal, internalization 
refers to a broker filling a customer order either from the firm's 
own inventory or by matching the order with other customer order 
flow, instead of sending the order to an interdealer market for 
execution. See id. at 3928 n.5.
---------------------------------------------------------------------------

    In the interdealer market, the majority of trading in on-the-run 
U.S. Treasury Securities currently occurs on ATSs using limit order 
books supported by advanced electronic trading technology.\197\ 
Furthermore, interdealer trading for on-the-run U.S. Treasury 
Securities is generally concentrated within a very small number of 
ATSs, especially when compared to the market for NMS stocks, which is 
dispersed among many trading venues.\198\ While

[[Page 15514]]

trading in the most liquid NMS stocks occur on a variety of trading 
venues (e.g., exchanges, ATSs, single-dealer broker platforms), the 
majority of overall trading in the interdealer secondary market for on-
the-run U.S. Treasury Securities occurs on ATSs.\199\ For example, 
during the first nine months of 2021, one ATS accounted for $14.9 
trillion in total dollar volume in all government securities, the 
majority of which were on-the-run U.S. Treasury Securities.\200\ For 
off-the-run U.S. Treasury Securities,\201\ the majority of interdealer 
trading occurs via transactions through traditional voice-assisted 
interdealer broker platforms and Communication Protocol Systems that 
offer various trading protocols to bring together buyers and 
sellers,\202\ though some interdealer trading of off-the-run U.S. 
Treasury Securities does occur on ATSs.\203\
---------------------------------------------------------------------------

    \197\ See October 15 Staff Report, supra note 188, at 11, 35-36. 
See also Bloomberg Letter at 5, stating that liquid on-the-run 
government securities are mostly traded on limit order books.
    \198\ The growth of electronic trading has contributed to a 
marked shift in the composition of the interdealer cash market for 
U.S. Treasury Securities over time. Traditionally, interdealer 
brokers only allowed primary dealers to access their trading venues. 
After 1992, however, interdealer brokers expanded access to all 
entities that were netting members of the Government Securities 
Clearing Corporation (which is now the Fixed Income Clearing 
Corporation's Government Securities Division). Thereafter, other 
entities gained access to these trading venues through their prime 
brokers, who themselves had access, and in recent years the trading 
venues granted direct access to an even wider range of participants, 
including non-dealers, which account for more than half of the 
trading activity in the futures and electronically brokered 
interdealer cash markets. See October 15 Staff Report, supra note 
188, at 36. See also Treasury Request for Information, supra note 
188, at 3928.
    \199\ See infra Table VIII.2 and accompanying text.
    \200\ For an additional discussion of trading volume in the U.S. 
bond market as a whole and U.S. Treasury Securities, see infra 
Section VIII.B.2.
    \201\ Also, as noted in the October 15 Staff Report issued by 
the Treasury Department, Board of Governors of the Federal Reserve 
System, Federal Reserve Bank of New York, the Commission, and U.S. 
Commodity Futures Trading Commission, trading in off-the-run U.S. 
Treasury Securities has always been less active than trading in on-
the-run U.S. Treasury Securities, and price discovery in the cash 
markets primarily occurs in on-the-run securities. See October 15 
Staff Report, supra note 188 at n.7.
    \202\ See November 2021 IAWG Report, supra note 184, at 3. See 
also Bloomberg Letter at 5, stating that less liquid off-the-run 
government securities are mostly traded using methods other than 
limit order books.
    \203\ While trading in on-the-run securities likely accounts for 
more than half of total daily trading volumes, off-the-run U.S. 
Treasury Securities make up over 95 percent of the outstanding 
marketable U.S. Treasury Securities. See G30 Report, supra note 183, 
at 1, n.2.
---------------------------------------------------------------------------

    Another type of government securities is Agency Securities. Agency 
Securities include securities issued by or guaranteed by U.S. 
Government corporations or U.S. Government sponsored enterprises 
(``GSEs'').\204\ Agency Securities, which may not be backed by the full 
faith and credit of the U.S. Government, are generally considered to be 
very liquid and offer state and local tax advantages to the holder. 
Market participants can use ATSs to buy and sell Agency Securities, 
although, based on the Commission's review of Form ATS-R filings, 
transaction volume of Agency Securities is not as large as that of U.S. 
Treasury Securities on ATSs.\205\ Investors, banks, and other market 
participants often acquire Agency Securities in the secondary market to 
support various investing strategies, such as hedging against other 
more risky investments in a given portfolio. Agency Securities also 
trade on Communication Protocol Systems where buyers and sellers can 
use RFQ protocols, for example, to engage in price discovery, find a 
counterparty, and negotiate and execute a transaction.
---------------------------------------------------------------------------

    \204\ See U.S. Department of the Treasury Resource Center, 
``Fixed Income: Agency Securities,'' available at <a href="https://www.treasury.gov/resource-center/faqs/Markets/Pages/fixedfederal.aspx">https://www.treasury.gov/resource-center/faqs/Markets/Pages/fixedfederal.aspx</a>. For example, the Government National Mortgage 
Association (``Ginnie Mae'') is a U.S. Government corporation that 
issues mortgage-backed securities guaranteed by the full faith and 
credit of the U.S. Government. The assets collateralized into the 
securities issued by Ginnie Mae are federally insured and guaranteed 
mortgage loans. Agency Securities issued by GSEs include those 
issued by the Federal Home Loan Banks (``FHLBs''), the Federal 
National Mortgage Association (``Fannie Mae''), the Federal Home 
Loan Mortgage Corporation (``Freddie Mac''), and the Student Loan 
Marketing Association (``Sallie Mae''). Agency Securities issued by 
GSEs are not normally backed by the full faith and credit of the 
U.S. Government and therefore, may present some default and credit 
risk.
    \205\ Additionally, repos on government securities are also 
traded on some ATSs.
---------------------------------------------------------------------------

    Repos provide short-term financing (often overnight) to help fund 
the borrower's (usually a broker-dealer) trading or lending activities. 
However, the collateral is sold to the lender, and the repo obligates 
the borrower to repurchase the collateral. U.S. Treasury Securities are 
frequently used as the underlying collateral of a repo. Several ATSs 
have provided notice on their Form ATS disclosures that they facilitate 
the trading of repos. Much like the markets for U.S. Treasury 
Securities and Agency Securities, repo trading has historically been 
conducted bi-laterally by voice; however, over the past decade, 
electronic trading of repos on Communication Protocol Systems has 
increased significantly. Electronic trading of repos is primarily 
conducted via RFQ protocols, and many systems for trading in repos now 
offer electronic trading options.
    With regard to the interdealer secondary markets for on-the-run 
U.S. Treasury Securities, the continued growth of electronic trading 
has contributed to an increased presence of PTFs in the market 
place.\206\ Currently, PTFs account for the majority of trading and 
provide top-of-the-book liquidity for on-the-run U.S. Treasury 
Securities on electronic interdealer trading venues.\207\ From January 
1, 2021 to June 30, 2021, PTFs traded on 13 Government Securities ATSs 
accounting for approximately 48.6 percent of total on-the-run 
Government Securities ATS trading volume.\208\ PTFs usually have direct 
access to electronic interdealer trading venues for U.S. Treasury 
Securities, and as is the case with the equity markets, PTFs trading on 
the electronic interdealer trading venues for on-the-run U.S. Treasury 
Securities often employ automated algorithmic trading strategies that 
rely on speed and allow the PTFs to cancel or modify quotes in response 
to perceived market events.\209\ Furthermore, most PTFs trading U.S. 
Treasury Securities on these trading venues for on-the-run U.S. 
Treasury Securities also restrict their activities to principal trading 
and do not hold positions long term, while dealers use the interdealer 
market as a source of orders and trading interest to help facilitate 
their trading with clients in the dealer-to-customer market.\210\ As 
explained in the October 15 Staff Report, the increase in trading by 
PTFs in the interdealer market may affect the amount of liquidity 
available to end users in the dealer-to-customer market.\211\
---------------------------------------------------------------------------

    \206\ PTFs are not, however, very active in the electronic 
markets for Agency Securities. See August 25th FEDS Notes, supra 
note 190 (``Though parts of the agency MBS market have moved from 
voice-based to screen-based trading since the early 2000s, 
algorithmic high-frequency electronic trading still does not 
comprise a meaningful share of average daily volume and the market 
remains devoid of PTF participation.'').

---------------------------------------------------------------------------

    In response to the 2020 Proposal, the Commission received several 
comments that broadly supported expanding the regulatory framework 
under Regulation ATS with respect to Government Securities ATSs.\212\ 
Commenters stated that ATSs have become increasingly important in the 
government securities market.\213\ One commenter stated that, given 
that Government Securities ATSs closely resemble NMS Stock ATSs, it 
would be appropriate to impose similar regulatory oversight, including 
regulatory oversight by the Commission

[[Page 15515]]

and FINRA.\214\ Likewise, another commenter stated that many of the 
concerns surrounding potential conflicts of interest that arise between 
an ATS and the activities of its bank/broker-dealer operator and 
affiliates--and the transparency of an ATS's operations--are equally 
relevant with respect to ATSs that transact in government securities as 
to NMS Stock ATSs.\215\ In addition, one commenter stated that critical 
intermediaries in the U.S. Treasury market are ``effectively 
unregulated'' as trading venues or dealers, and this hampers 
availability of information concerning trading in these critical 
markets, and that oversight of the core ``plumbing'' of these critical 
markets, which determines their resiliency, is lacking.\216\ This 
commenter stated that several ATSs now dominate the trading of U.S. 
Treasury Securities and agency mortgage backed securities, and that 
ensuring that Regulation ATS and Regulation SCI apply to these entities 
will provide for additional data and create more transparency into the 
trading around those critical markets.\217\ This commenter also stated 
that expanding Regulation ATS with respect to ATSs that trade U.S. 
Treasuries has also become important as the role of PTFs has become 
more significant in the U.S. Treasury markets and related repo 
markets.\218\

    \216\ See AFREF Letter at 1.
    \217\ See id.
    \218\ See id. at 2 (stating that the growing role of PTFs means 
that much trading activity is not coming from long-term investors 
but rather proprietary trading firms who may trade in-and-out of 
their positions several times in a day and are likely to react 
sharply to market volatility).
---------------------------------------------------------------------------

B. Heightened Regulatory Requirements Under Regulation ATS for 
Government Securities ATSs

    The vast majority of ATSs that operate today do so pursuant to the 
exemption provided by Exchange Act Rule 3a1-1(a)(2), which requires the 
ATSs to be in compliance with Regulation ATS, which includes, among 
other things, registering as broker-dealers. Currently Exempted 
Government Securities ATSs, however, operate pursuant to Exchange Act 
Rule 3a1-1(a)(3) \219\ and Rule 301(a)(4)(ii)(A).\220\ These provisions 
currently exempt an ATS from compliance with the requirements in Rule 
301(b) of Regulation ATS \221\ if, in relevant part, the ATS (1) is 
registered as a broker-dealer under Sections 15(b) \222\ or 15C \223\ 
of the Exchange Act, or is a bank, and (2) limits its securities 
activities to government securities (as defined in Section 3(a)(42) of 
the Exchange Act), repos, any puts, calls, straddles, options, or 
privileges on government securities, other than puts, calls, straddles, 
options, or privileges that: (i) Are traded on one or more national 
securities exchanges; or (ii) for which quotations are disseminated 
through an automated quotation system operated by a registered 
securities association, and commercial paper.\224\ Accordingly, such 
Currently Exempted Government Securities ATSs are not required to 
register as a national securities exchange or comply with Regulation 
ATS.\225\ To the Commission's knowledge, most Currently Exempted 
Government Securities ATSs operating pursuant to this exemption 
register as broker-dealers with the Commission.\226\
---------------------------------------------------------------------------

    \219\ 17 CFR 240.3a1-1(a)(3).
    \220\ 17 CFR 242.301(a)(4)(ii)(A).
    \221\ 17 CFR 242.301(b).
    \222\ See 15 U.S.C. 78o(b) (pertaining to the registration and 
regulation of brokers and dealers).
    \223\ See 15 U.S.C. 78o-5 (pertaining to the registration and 
regulation of government securities brokers and dealers).
    \224\ See 15 U.S.C. 78c(a)(42). The definition of ``government 
securities'' in Section 3(a)(42) of the Exchange Act (and, 
therefore, references to ``government securities'' throughout this 
proposal) includes certain puts, calls, straddles, options, or 
privileges on government securities, other than puts, straddles, 
options, or privileges that: Are traded on one or more national 
securities exchanges; or for which quotations are disseminated 
through an automated quotation system operated by a registered 
securities association. See supra note 182.
    \225\ See 17 CFR 242.301(a)(4)(i) and (a)(4)(ii)(A). Although 
not required to register as a national securities exchange or comply 
with Regulation ATS, a Currently Exempted Government Securities ATS 
may need to register as a broker-dealer under Section 15(b) or as a 
government securities broker or government securities dealer 
pursuant to Exchange Act Section 15C, and comply with the associated 
regulatory requirements. See, e.g., 17 CFR chapter IV, subchapter 
A--Regulations under Section 15C of the Securities Exchange Act of 
1934.
    \226\ Some ATSs that are eligible for the exemption voluntarily 
comply with Regulation ATS, even though ATSs that trade only 
government securities are not required to comply with Regulation ATS 
at all.
---------------------------------------------------------------------------

    ATSs that do not limit their securities activities solely to 
government securities or repos, trading for example corporate bonds or 
municipal securities, cannot use this exemption. Such ATSs must either 
register as an exchange or comply with Regulation ATS pursuant to 
Exchange Act Rule 3a1-1(a)(2), which includes, among other things, 
registering as a broker-dealer under Section 15 of the Exchange 
Act.\227\ Government Securities ATSs that are currently subject to 
Regulation ATS must report transactions in U.S. Treasury Securities and 
Agency Securities to the Trade Reporting and Compliance Engine 
(``TRACE''),\228\ and FINRA publicly disseminates data about these 
transactions. Currently, FINRA publishes weekly aggregated transaction 
information on U.S. Treasury Securities and disseminates certain 
transaction information on Agency Securities immediately upon receipt 
of a transaction report.\229\ Today, Legacy Government Securities ATSs 
are subject only to certain provisions of Regulation ATS because not 
all the provisions are applicable to trading in government 
securities.\230\ In particular, government securities are not included 
in any category of securities under the Fair Access Rule.\231\ Today, 
the categories of securities under the Fair Access Rule only include 
NMS stocks, equity securities that are not NMS stocks and for which 
transactions are reported to an SRO, municipal securities, and 
corporate debt securities.\232\ In addition, Regulation SCI does not 
apply to ATSs with respect to their trading in

[[Page 15516]]

government securities.\233\ The Capacity, Integrity, and Security Rule 
under Rule 301(b)(6) \234\ also does not apply to the government 
securities activities of an ATS.\235\
---------------------------------------------------------------------------

    \227\ See supra notes 130-131 and accompanying text.
    \228\ See FINRA Rule 6730(a)(1) requires FINRA members to report 
transactions in TRACE-Eligible Securities, which FINRA Rule 6710 
defines to include U.S. Treasury Securities and Agency Securities. 
For each transaction in U.S. Treasury Securities and Agency 
Securities, a FINRA member would be required to report the CUSIP 
number or similar numeric identifier or FINRA symbol; size (volume) 
of the transaction; price of the transaction (or elements necessary 
to calculate price); symbol indicating whether transaction is a buy 
or sell; date of trade execution (``as/of'' trades only); contra-
party's identifier; capacity (principal or agent); time of 
execution; reporting side executing broker as ``give-up'' (if any); 
contra side introducing broker (in case of ``give-up'' trade); the 
commission (total dollar amount), if applicable; date of settlement; 
if the member is reporting a transaction that occurred on an ATS 
pursuant to FINRA Rule 6732, the ATS's separate Market Participant 
Identifier (``MPID''); and trade modifiers as required. For when-
issued transactions in U.S. Treasury Securities, a FINRA member 
would be required to report the yield in lieu of price. See FINRA 
Rule 6730(c).
    \229\ FINRA Rule 6750(a) requires FINRA to disseminate 
information on all transactions on certain securities, including 
Agency Securities (but excluding U.S. Treasury Securities), 
immediately upon receipt of the transaction report. FINRA is 
permitted to publish or distribute weekly aggregated transaction 
information and statistics on U.S. Treasury Securities, and has 
stated that it intends to publish weekly volume information 
aggregated by U.S. Treasury subtype (e.g., Bills, Floating Rate 
Notes, Treasury Inflation-Protected Securities, and Nominal 
Coupons). See Securities Exchange Release No. 87837 (December 20, 
2019), 84 FR 71986 (December 30, 2019) (approving a proposed rule 
change to allow FINRA to publish or distribute aggregated 
transaction information and statistics on U.S. Treasury Securities).
    \230\ See 17 CFR 242.301(b)(1), (2), and (7) through (11). The 
order display and execution access provisions under Rule 301(b)(3) 
and the related fee restrictions of Rule 301(b)(4) of Regulation ATS 
only apply to an ATS's NMS stock activities. See 17 CFR 
242.301(b)(3) and (4). See also supra Section II.D.2 (discussing the 
requirements for compliance with the Regulation ATS exemption).
    \231\ 17 CFR 242.301(b)(5). See also supra notes 153-157 and 
accompanying text.

---------------------------------------------------------------------------

    Finally, Government Securities ATSs are not required to comply with 
rules applicable to ATSs that trade NMS stocks, including the 
obligation to file a public Form ATS-N pursuant to Rule 304 of 
Regulation ATS.\236\ ATSs that transact in government securities or 
repos are also not required to comply with the order display and 
execution access provisions under Rule 301(b)(3) \237\ and the related 
fee restrictions of Rule 301(b)(4),\238\ both of which only apply to an 
ATS's NMS stock activities.

---------------------------------------------------------------------------

    Despite the critical role of government securities in the U.S. and 
global economy, the significant volume in government securities 
transacted on ATSs, and these ATSs' growing importance to investors and 
overall securities market structure, Currently Exempted Government 
Securities ATSs are exempt from exchange registration and are not 
required to comply with Regulation ATS. In addition, Communication 
Protocol Systems that transact in government securities and/or repos, 
but do not currently meet the definition of ``exchange,'' are not 
subject to exchange registration requirements and are likewise not 
required to comply with Regulation ATS.\239\ Furthermore, ATSs that 
trade both government securities and non-government debt securities 
(e.g., corporate bonds) are not subject to all the provisions of 
Regulation ATS. Market participants today have limited access to 
information that permits them to adequately compare and contrast how 
they can use a Government Securities ATS or how their trading interest 
would be handled by Government Securities ATSs.\240\ In addition, 
Government Securities ATSs are not currently subject to the Fair Access 
Rule and Regulation SCI, which would help ensure the fair treatment of 
subscribers and address technological vulnerabilities, and improve the 
Commission's oversight, of the core technology of key entities in the 
markets for government securities.\241\ Given these concerns, and 
comments received on the 2020 Proposal, the Commission is re-proposing 
and revising the amendments described below.
---------------------------------------------------------------------------

    \239\ See supra Section II.A.
    \240\ See, e.g., 2020 Proposal, supra note 4, at 87125.
    \241\ See id. at Section III.B.4 (discussing the Fair Access 
Rule) and III.C (discussing Regulation SCI).
---------------------------------------------------------------------------

1. Proposed Definition of Government Securities ATS
    The Commission is re-proposing to amend Rule 300 of Regulation ATS 
to define ``Government Securities ATS'' to mean an alternative trading 
system, as defined in Rule 300(a), that trades government securities, 
as defined in section 3(a)(42) of the Exchange Act (15 U.S.C. 
78c(a)(42)), or repurchase and reverse repurchase agreements on 
government securities.\242\ To meet the definition of a Government 
Securities ATS, the organization, association, person, group of 
persons, or system must meet the definition of an alternative trading 
system under Rule 300(a) of Regulation ATS.\243\ The Commission is also 
re-proposing that a Government Securities ATS shall not trade 
securities other than government securities or repos \244\ and that 
trading of securities other than government securities or repos would 
require the separate filing of a Form ATS or a Form ATS-N, depending on 
the types of securities traded.\245\ Other than complying with Rule 304 
and filing Form ATS-N, this amendment would not, however, impose new 
compliance requirements on ATSs that currently trade government 
securities in addition to non-government securities.\246\ Under the 
proposal, if a broker-dealer operator currently operates an ATS for 
government securities and non-government securities (for example, 
corporate bonds), the broker-dealer operator would separately be 
required to comply with Regulation ATS for: (1) A Government Securities 
ATS that would trade government securities, which would be subject to 
Rule 304, and file disclosures on Form ATS-N, as proposed to be revised 
and (2) a non-Government Securities ATS (that, for example, would trade 
corporate bonds), which would not be subject to Rule 304, and file 
disclosures on its existing Form ATS, as amended to remove references 
to government securities.
---------------------------------------------------------------------------

    \242\ See proposed Rule 300(l).
    \243\ 17 CFR 242.300(a). See Regulation ATS Adopting Release, 
supra note 31, at 70851-52.
    \244\ See proposed Rule 300(l).
    \245\ An ATS that does not trade NMS stocks or government 
securities, as proposed, must file Form ATS. If the broker-dealer 
operates an ATS that trades NMS stocks and an ATS that trades 
government securities, it would be required to file a separate Form 
ATS-N for each of the NMS Stock ATS and Government Securities ATS.
    \246\ Broker-dealers that operate Government Securities ATSs 
that are currently subject to Regulation ATS already must have 
established written safeguards and written procedures to protect 
subscribers' confidential trading information, pursuant to Rule 
301(b)(10), and already must make and keep records pursuant to Rule 
301(b)(8) that are tailored to the types of securities the ATS 
trades and the subscribers that trade those securities on the ATS. 
The Commission believes the proposal is broadly consistent with the 
manner in which broker-dealers that operate NMS Stock ATSs and non-
NMS Stock ATSs currently comply with Regulation ATS. For further 
discussion, see infra Section III.B.3.
---------------------------------------------------------------------------

    In response to the 2020 Proposal, the Commission received one 
comment letter opposing the proposed definition of Government 
Securities ATS.\247\ This commenter stated that separating trading 
activity in government securities and repos from non-NMS stock trading 
activity could impose administrative and operational burdens on both 
Government Securities ATSs and subscribers.\248\ The commenter stated 
that the Commission did not explain why requiring a Government 
Securities ATS to separate its operations from other non-NMS Stock ATS 
trading activity would improve Commission oversight or other regulatory 
goals.\249\
---------------------------------------------------------------------------

    \247\ See ICE Bonds Letter I at 5.
    \248\ See id. The commenter stated that the initial set-up of a 
new Government Securities ATS would require, among other things, the 
development of a matching engine, separate connectivity for 
subscribers, new clearing connectivity, additional personnel to 
support trading operations of the Government Securities ATS, and 
regulatory controls (e.g., Rule 15c3-5). The commenter further 
stated that these requirements would ultimately lead to fewer venues 
for subscribers to trade and hedge and concentrate trading among a 
few large Government Securities ATSs, as smaller Legacy Government 
Securities ATSs may determine that this separation requirement is 
cost prohibitive. In addition, the commenter stated that if a 
subscriber has to execute a corporate bond on one ATS and sell the 
treasury on a different ATS, there is an administrative and 
operational burden placed on the subscriber, as well as additional 
economic and market risk to the subscriber as the price on the other 
venue may move by the time the hedge trade is initiated.
    \249\ See id.
---------------------------------------------------------------------------

    The proposed definition of Government Securities ATS, however, 
would not require operational separation by a Government Securities 
ATS, and the operational costs that the commenter described would 
therefore not apply.\250\ The proposed definition would not, for 
example, require the Government Securities ATS to develop a new 
matching engine nor require changes with regard to how subscribers 
enter trading interest into the ATS. Other than requiring the 
Government Securities ATS to separately comply with the requirements of 
Regulation ATS (and, as applicable, Regulation SCI), the proposed 
definition does not create new compliance requirements on

[[Page 15517]]

Government Securities ATSs.\251\ Under the proposed rule, a broker-
dealer operator for an ATS that currently trades both government 
securities and corporate debt securities, for example, would be 
required to file a Form ATS-N for the trading of government securities 
on a Government Securities ATS and a separate Form ATS for trading of 
corporate debt securities on an ATS. In this example, the broker-dealer 
operator for a Government Securities ATS and non-Government Securities 
ATS may be required to disclose certain information on Form ATS-N about 
the non-Government Securities ATS. For example, to the extent that any 
persons support both the operation of the Government Securities ATS and 
the ATS that trades corporate debt securities and have access to 
subscriber confidential trading information for the Government 
Securities ATS, the Government Securities ATS would need to disclose 
that on Part II, Item 7 of Form ATS-N.\252\ In addition, the Government 
Securities ATS would be required to provide under Part III, Item 11 
information about interaction with non-government securities markets 
(e.g., futures, currencies, swaps, corporate bonds).\253\
---------------------------------------------------------------------------

    \250\ See id.
    \251\ See supra note 246.
    \252\ See infra Section IV.D.4.f.
    \253\ See infra Section IV.D.5.k.
---------------------------------------------------------------------------

    Further, the Commission believes that by stating that a Government 
Securities ATS trades only government securities, the definition of 
Government Securities ATS clarifies which regulatory requirements are 
applicable for trading activity in government securities and non-
government securities. For example, a Government Securities ATS would 
file a Form ATS-N specifically disclosing information regarding its 
trading in government securities, which would enable market 
participants to understand the ATS's government securities operations 
and readily compare the ATS against other Government Securities ATSs.
    To provide that the same approach applies to broker-dealers that 
operate NMS Stock ATSs and non-NMS Stock ATSs, and to clarify 
requirements applicable to NMS Stock ATSs, the Commission is proposing 
to amend the definition of ``NMS Stock ATS'' to state that an NMS Stock 
ATS shall not trade securities other than NMS stocks.\254\ Today, 
securities other than NMS stocks are not traded in any NMS Stock ATS 
and the proposed amendment to the definition of NMS Stock ATS would 
have no impact on any existing ATS nor on the requirements applicable 
to existing NMS Stock ATSs. Broker-dealer operators of NMS Stock ATSs 
are currently required to file a Form ATS-N for NMS Stock ATS 
operations and a separate Form ATS for any non-NMS Stock ATS 
operations.\255\ This would not change under this proposal. In 
addition, to facilitate the orderly transition to the heightened 
requirements for Government Securities ATSs that are currently 
operating, the Commission is defining such ATSs as Legacy Government 
Securities ATSs.\256\
---------------------------------------------------------------------------

    \254\ See proposed Rule 300(k).
    \255\ See current Rule 301(b)(2)(viii).
    \256\ See proposed Rule 300(n). See also supra note 5. See infra 
notes 433-439 and accompanying text for a description of the filing 
and effectiveness rules applicable to Legacy Government Securities 
ATSs.
---------------------------------------------------------------------------

    To help specify which ATSs are subject to Rule 304 requirements, 
the Commission is proposing to define ``Covered ATS'' as an NMS Stock 
ATS or Government Securities ATS, as applicable.\257\ The Commission is 
also proposing to define ``Covered Newly Designated ATS'' to mean a 
Newly Designated ATS that is a Government Securities ATS or NMS Stock 
ATS, which the Commission believes would facilitate the transition of 
Communication Protocol Systems that are NMS Stock ATSs or Government 
Securities ATSs to the regulatory requirements of Regulation ATS.\258\
---------------------------------------------------------------------------

    \257\ See proposed Rule 300(m).
    \258\ See proposed Rule 300(s).
---------------------------------------------------------------------------

    The Commission is also proposing to add definitions of ``U.S. 
Treasury Security'' and ``Agency Security'' for purposes of Regulation 
ATS.\259\ ``U.S. Treasury Security'' would mean a security issued by 
the U.S. Department of the Treasury. ``Agency Security'' would mean a 
debt security issued or guaranteed by a U.S. executive agency, as 
defined in 5 U.S.C. 105, or government-sponsored enterprise, as defined 
in 2 U.S.C. 622(8). The proposed definitions are designed to provide 
the scope of securities a Government Securities ATS must include when 
calculating whether the fair access requirements set forth in Rule 
301(b)(5) are applicable and to facilitate compliance with the Fair 
Access Rule.\260\
---------------------------------------------------------------------------

    \259\ See proposed Rule 300(o)-(p).
    \260\ See infra Section III.B.4. The proposed definitions are 
similar to those in FINRA's rules. See FINRA Rules 6710(l) and 
6710(p).
---------------------------------------------------------------------------

Request for Comment
    12. Should the Commission adopt a more limited or expansive 
definition of Government Securities ATS than the definition that is 
being proposed? Given that, unlike the 2020 Proposal, the definition of 
Government Securities ATS would now include Communication Protocol 
Systems that transact in government securities and/or repos, do 
commenters believe that the definition of Government Securities ATS 
should be limited or expanded?
    13. Should the Commission cite to the section 3(a)(42) (15 U.S.C. 
78c(a)(42)) definition of government securities for purposes of 
defining Government Securities ATS? Should the securities encompassed 
by the definition (e.g., certain options on government securities) be 
considered ``government securities'' for purposes of this regulation?
    14. Should the Commission modify the proposed definitions of U.S. 
Treasury Securities and Agency Securities in any way? For example, 
should the proposed definitions of U.S. Treasury Securities and Agency 
Securities be based on definitions in any other existing rules?
    15. The proposed amendments to the definitions of NMS Stock ATS and 
Government Securities ATS are not designed to limit a broker-dealer 
operator for an NMS Stock ATS or Government Securities ATS with respect 
to other types of securities that the broker-dealer operator may make 
available for trading in an ATS that is subject to Rule 301(b)(2) of 
Regulation ATS or how the broker-dealer operator may structure the 
operations of its ATS businesses. Would the proposed amendments to the 
definitions of NMS Stock ATS and Government Securities ATS impose any 
operational or other burdens on the broker
