Re: Regulation NMS (File No. S7-10-04)
Dear Mr. Katz:
The Investment Company Institute1 appreciates the opportunity to comment on the
Securities and Exchange Commission’s reproposed Regulation NMS,2 which is intended to
enhance and modernize the regulatory structure of the U.S. equity markets. Regulation NMS is
an essential step in the development of a market structure that best serves all investors.
As the Institute stated in our previous comment letter on the Regulation NMS proposal,3
because our members are investors of over $7.8 trillion of assets on behalf of over 87 million
individual shareholders, we have a strong interest in ensuring that the regulatory structure that
governs the securities markets encourages liquidity, transparency and price discovery in order
to facilitate the trading of institutional-sized orders. As the Release notes, “given that millions
of individuals invest in NMS stocks directly through [institutional investors], it is vitally
important for the NMS to promote depth and liquidity for the trading of large orders.”4 We
commend the Commission for undertaking such an extensive examination of the structure of
the U.S. equity markets and for reproposing Regulation NMS to provide an additional
opportunity to comment on the details of such a significant proposal.
Given that the majority of changes in the reproposal center on the trade-through rule,
we focus our comments on that proposed rule, specifically on whether there is a need for a
trade-through rule and the scope of such a rule. As discussed in greater detail below, the

Institute strongly supports the establishment of a uniform trade-through rule across all market
centers and for all types of securities, including Nasdaq-listed securities. In addition, we
strongly support the goals of the proposed depth of book alternative (i.e., full protection for
displayed and accessible limit orders, strong linkages between markets and the opportunity for
automated executions at the best available prices). Our members have differing views on
whether the optimal path towards achieving those goals is through adoption of the proposed
“top of book” or “depth of book” alternative. While there are strong arguments for both of
these alternatives, we believe it is imperative that the Commission adopt one of the proposed
versions of a marketwide trade-through rule, as either alternative is preferable to the status quo.
Our specific comments follow.5
Trade-Through Rule Proposal
The proposed trade-through rule would require an order execution facility, national
securities exchange and national securities association, with regard to the trading of “NMS
Stocks,” to establish, maintain, and enforce policies and procedures reasonably designed to
prevent the purchase or sale of an NMS Stock at a price that is inferior to a better price
displayed on another market.
Need for Trade-Through Rule
The Institute strongly supports the establishment of a marketwide trade-through rule.
As the Institute discussed in detail in its 2004 Regulation NMS letter, such a rule represents a
significant step in providing protection for limit orders. By affirming the principle of price
priority, a trade-through rule should encourage the display of limit orders, which in turn would
improve the price discovery process and contribute to increased market depth and liquidity. A
trade-through rule also would increase investor confidence in the securities markets by helping
to eliminate an impression of unfairness when an investor’s order executes at a price worse than
the displayed quote. For these reasons, we strongly recommend that the Commission adopt a
trade-through rule for the securities markets.
Critics of a trade-through rule contend that the adoption of such a rule would, among
other things, dampen competition between markets. We recognize that achieving the ultimate
balance between competition among markets and regulation of those markets is a difficult
challenge. We believe, however, that allowing markets to trade in isolation from one another
without the benefit of a trade-through rule is not the best result for investors. Moreover, it must
be recognized that the goal of facilitating competition among markets can at times be
inconsistent with the more important goal of facilitating competition among orders.
Application of Trade-Through Rule to Nasdaq-Listed Securities
The reproposed trade-through rule would apply uniformly to all market centers and
would apply to all NMS securities, including Nasdaq-listed securities. As reflected in our 2004

rule not addressed in this letter, see 2004 Regulation NMS letter, supra note 3.

Regulation NMS letter, the Institute continues to support such an application of the trade-
through rule.6
The Release notes that several commenters on the original proposal stated that they
believe it is unnecessary to apply a trade-through rule to Nasdaq-listed securities because those
securities have, for the most part, functioned efficiently without a formal trade-through
requirement and that a broker-dealer’s best execution obligations obviates the need for a strict
trade-through rule across all market centers. The Institute continues to believe that there is
significant value in protecting a displayed price from trades occurring at inferior prices across
all markets and in all types of securities. A uniform trade-through rule would affirm the
principle of price priority and the protection of the best prices for all markets. We believe it
would be anomalous to provide trade-through protection to only a certain group of investors,
based solely on the type of security and market in which they invest. A uniform trade-through
rule also would provide an additional layer of protection for investors in the execution of their
orders over and above a broker’s best execution obligations. Finally, as the Release notes, trade-
throughs do occur in Nasdaq-listed securities. A uniform rule could prevent such trade-
throughs from occurring and, if they do occur, could provide effective policies and procedures
for obtaining restitution. For these reasons, we strongly recommend that the Commission
adopt a uniform trade-through rule that applies across all market centers and to all types of
NMS securities, including Nasdaq-listed securities.
“Top of Book” and “Depth of Book” Alternatives
The Release sets forth two alternatives to the proposed trade-through rule and requests
comment on which alternative would best advance the principle of limit order protection while
preserving intermarket competition and avoiding practical implementation problems. The first
alternative (“top-of-book” alternative) would protect only the best bids and offers (“BBOs”) of
the exchange SROs, Nasdaq, and the NASD’s Alternative Display Facility (“ADF”). The second
alternative (“depth-of-book” alternative) also would protect the BBOs of the various exchange
SROs, Nasdaq and the ADF, and would additionally protect the depth of book quotations at
prices beyond the best bid and offer that a market voluntarily disseminates in the consolidated
quotations stream.
The Institute strongly supports the goals of the depth of book alternative, and believes
that it would be beneficial for market centers to work towards the implementation of its most
significant features (i.e., full protection for displayed and accessible limit orders, strong linkages
between markets and the opportunity for automated executions at the best available prices).
Our members have differing views, however, on whether the optimal path towards achieving
those goals is through adoption of the proposed “top of book” or “depth of book” alternative.
6 The Institute also supports the Commission’s decision in the reproposal to limit the trade-through rule’s protection
to automated and accessible quotations and to eliminate the proposed limitation on trade-through amounts for
manual markets and quotations. We believe the proposed definition of an automated quotation addresses our
concerns over including in a trade-through rule those quotations that are not truly automated. Similarly, the Institute
supports the Commission’s decision to set forth requirements for a trading center to qualify as an “automated trading
center.”

Several Institute members believe that the Commission should adopt the depth of book
alternative. They believe that this approach would best advance the principle of limit order
protection, thereby increasing the benefits of the proposed trade-through rule. In particular,
protecting quotations at multiple price levels would provide greater protection to displayed
limit orders which, in turn, would be more likely than the top of book alternative to encourage
increased use of such orders.
In addition, the depth of book alternative would eliminate situations that would arise
under the top of book alternative where liquidity in certain markets would be bypassed. For
example, assume Market A is displaying 500 shares at the national best offer of $20.02 (and also
has offers at each price level below the best offer), Market B is displaying 500 shares at $20.03
(its best offer) and 20,000 shares at $20.04, Market C is displaying 300 shares at $20.05 (its best
offer), and Market D is displaying 800 shares at $20.07 (its best offer). Under the top of book
alternative, if an order arrives at Market A to buy a significant amount of shares that would
satisfy all the displayed liquidity in the other markets, Market A would only be required to
send orders to satisfy the best offers at Markets B, C, and D. The 20,000 share order on Market
B, even though it is for a significant amount of stock, would be ignored and would remain
unexecuted in favor of inferior-priced orders. Our members supporting the depth of book
alternative believe that such a result would run counter to the Commission’s goal of providing
incentives for investors to place limit orders into the securities markets.
Other Institute members believe that the best way to support the goals of the depth of
book alternative is for the Commission to take the incremental step of adopting the top of book
alternative. They are concerned that inexperience with depth of book intermarket trade
through protection raises uncertainties regarding the impact of the depth of book alternative on
institutional trading. These members also believe that the competition created by the top of
book alternative ultimately will drive the securities markets to implement the features of a
depth of book market structure, which is a more favorable means of achieving the goals of the
depth of book alternative than through a specific government mandate. In this regard, these
members note that the debate over Regulation NMS and the proposal to limit the protections of
a trade-through rule to automated quotes has prompted the New York Stock Exchange to
develop a hybrid market proposal, which incorporates features of an automated market into the
NYSE’s current manual market structure.7
There are strong arguments for both of the proposed alternatives. Regardless of which
alternative the Commission ultimately chooses, we urge the Commission to adopt one of these
approaches, as either alternative is preferable to the status quo, which does not protect, or
provide incentive to display, limit orders in the national market system.
7 While several members support the top of book alternative in order to preserve the choice of market in which to
execute their orders, all of our members agree that the NYSE should make certain changes to its hybrid market
proposal to provide investors with the necessary protection for limit orders placed on the Exchange and to provide
incentive to place orders into that market. Specifically, as the Institute stated in its comment letters on the hybrid
market proposal, certain features of the hybrid market, most significantly, the lack of priority for displayed investor
orders, will result in a disincentive to place limit orders on the Exchange or to utilize the “sweep” function of the
hybrid market. See Letters from Ari Burstein, Associate Counsel, Investment Company Institute, to Jonathan G. Katz,
Secretary, Securities and Exchange Commission, dated September 22, 2004 and December 13, 2004.

Application of Trade-Through Rule Solely to NBBO
Critics of the top of book and depth of book alternatives have suggested that the
Commission limit the protections of the trade-through rule solely to the national best bid and
offer (“NBBO”). The Institute strongly opposes such a proposal.
Limiting price protection solely to the NBBO would, in effect, make any trade-through
rule a fallacy. As soon as an order at the NBBO is executed, which can be for an amount as
small as 100 shares displayed in a single market, all other investor orders in all other markets
would not be provided protection. We believe such a result would be inconsistent with the
Commission’s goals in adopting a trade-through rule.
Proposed Exceptions to Trade-Through Rule
Although the Institute did not support the proposed opt-out exception in the original
Regulation NMS proposal, our 2004 Regulation NMS comment letter noted that it is extremely
important that any market structure facilitate the execution of institutional-sized orders. 8 We
therefore strongly support the exceptions to the trade-through rule for “benchmark” orders and
“intermarket sweep” orders that are designed to help ensure that the trade-through rule is
feasible for institutional orders.
The benchmark order exception would except from the provisions of the trade-through
rule the execution of an order at a price that was not based, directly or indirectly, on the quoted
price of an NMS Stock at the time of execution. To comply with this exception, the material
terms of the order also must not be reasonably determinable at the time the commitment to
execute the order was made. The Release notes that a common example of a benchmark order
is a volume weighted average (“VWAP”) order. The Institute seeks clarification that the
benchmark order exception would provide flexibility for institutions to execute other types of
average price trades outside of the provisions of the trade-through rule. Specifically, our
members report that while they execute trades on a VWAP basis, they also often execute other
types of average price trades, including variations on a VWAP trade (e.g., trades that improve
upon the VWAP price by a certain amount). Similar to a regular VWAP order, the price of such
orders would not be based on the quoted price of an NMS Stock at the time of execution and the
material terms of the trade would not reasonably be determinable at the time the commitment
to execute the order was made.
The Institute also supports the intermarket sweep order exception. The intermarket
sweep order exception would allow market participants to simultaneously access multiple price
8 The Institute strongly supports the Commission’s decision to eliminate the “opt-out” exception to the proposed
trade-through rule. The opt-out exception would have permitted a person for whose account an order is entered to
opt-out of the protections of the trade-through rule by providing informed consent to the execution of their orders in
one market without regard to the possibility of obtaining a better price in another market. As the Institute stated in
its 2004 Regulation NMS letter, if the Commission restricts the trade-through rule to automated quotes and adopts a
manual quote exception, then the opt-out exception would be unnecessary. The elimination of any protection for
manual quotations in the reproposal achieves this objective. In addition, as the Release notes, given the proposed
exceptions to the trade-through rule that would facilitate the execution of institutional-sized orders, the need for an
opt-out exception is significantly reduced.

levels at different trading centers.9 Specifically, the exception would enable trading centers that
receive sweep orders to execute those orders immediately, without regard for better-priced
quotations displayed at one or more other trading centers and without waiting for better-priced
quotations in other markets to be updated. As the Release notes, such an exception can be used
to execute block transactions, as long as orders have been routed to access all better priced
protected quotations. Because this exception would require an attempt to access all better-
priced protected quotations up to their displayed size, we believe that it is consistent with the
principle of protecting all orders priced better than the block transaction. At the same time, this
exception would permit institutional investors to continue to execute large sized orders in an
efficient manner.10

9 An intermarket sweep order is defined as a limit order that meets the following requirements: (1) the limit order is
identified as an intermarket sweep order when routed to a trading center, and (2) simultaneously with the routing of
the limit order, one or more additional limit orders are routed to execute against all better-priced protected
quotations displayed by other trading centers up to their displayed size.
10 The reproposal also includes several exceptions that are designed to limit the application of the trade-through rule
to quotations that are truly automated and accessible and that would address the difficulties of protecting quotations
displayed by other trading centers. Specifically, the reproposal would include exceptions for quotations displayed by
markets that fail to meet the response requirements for automated quotations and for “flickering” quotations. The
Institute supports these exceptions. As the Release notes, these exceptions would provide trading centers with
needed flexibility to deal with a trading center that is experiencing systems problems, rather than forcing smoothly-
functioning trading centers to slow down for a problem market. The exceptions also would address false indications
of trade-throughs that in actuality are attributable to rapidly moving quotations.
