1 Securities Exchange Act Release No. 42212 (December 9, 1999), 64 FR 70297 (December 16, 1999).
2 Current signatories to the ITS Plan include the American Stock Exchange, Boston Stock Exchange, Chicago Board Options
Exchange, Chicago Stock Exchange, Cincinnati Stock Exchange, National Association of Securities Dealers, New York Stock
Exchange, Pacific Exchange, and Philadelphia Stock Exchange (collectively, “ITS Participants”).
3 The CAES is a computer assisted execution system that enables participating firms to route their orders for listed securities
through the system to obtain automatic executions against quotations of third market makers.
4 Currently, only Securities Exchange Act Rule 19c-3 securities are ITS eligible. Rule 19c-3 allows a security that was listed on
an exchange after April 26, 1979 to trade “off the floor” of an exchange on which it was listed.
5 The term “third market” refers to the OTC market in listed securities.

SEC RULES COMMITTEE No. 114-99
RE: SEC ADOPTS AMENDMENTS TO THE INTERMARKET TRADING SYSTEM
PLAN TO EXPAND THE ITS LINKAGE TO ALL LISTED SECURITIES
______________________________________________________________________________
The Securities and Exchange Commission (“SEC”) is adopting amendments1 to the plan
governing the operation of the Intermarket Trading System (“ITS Plan”).2 The amendments expand the
NASD’s ITS/Computer Assisted Execution System ("CAES")3 linkage to all listed securities, including
non-Rule 19c-3 securities.4 The amendments become effective on February 14, 2000.
The SEC stated that it believes that it is necessary to expand the ITS/CAES linkage to all listed
securities in order to create a national market system linking the exchanges and the over-the-counter
(“OTC”) market. When the SEC originally approved the ITS linkage, it did so only for Rule 19c-3
securities. At that time, however, the SEC only intended the approval to be the first step toward a more
expansive linkage.
Since the original approval of the ITS, there has been a marked increase in the level of trading in,
and several significant improvements to, the third market.5 Specifically, any NASD member that acts in
the capacity of an OTC market maker must provide continuous two-sided quotations in certain
exchange-listed securities. In addition, the NASD prohibits third market makers from trading ahead of
their own customer limit orders. Finally, the Limit Order Display Rule requires third market makers to
display customer limit orders in their quote if those orders improve the quote.
In light of these changes, the SEC stated that there is no longer any need for the historical
distinction between Rule 19c-3 and non-Rule 19c-3 securities in the ITS/CAES linkage. The SEC
2believes that expanding the ITS linkage will increase a broker-dealer's ability to obtain the best price
available for the customer, promote competition in listed securities, help ensure more equivalent access
to the markets, and provide for additional liquidity and more efficient executions.
In the proposing release, the SEC requested comment on whether ECNs should be required or
allowed to participate in the ITS, and if so, what form that participation should take. The SEC stated in
the adopting release that most of the commenters who discussed the issue supported ECN access to the
ITS in some form. The SEC also stated that it believes that, in order to further the goals of the national
market system, ECNs trading in listed securities should be linked to the ITS and that the ITS should not
prevent efficient electronic routing between markets. The amended ITS Plan, however, does not include
ECNs. The SEC noted that ITS Participants have begun a dialogue about the parameters of ECN
access to the ITS and strongly urged ITS Participants to continue to discuss the issue and reach a
resolution.
In the proposing release, the SEC also proposed to eliminate the requirement that amendments
to the ITS Plan be approved unanimously. In the adopting release, the SEC stated that it has decided to
defer consideration of that proposal at this time and plans to deal with this and several other larger issues
relating to market structure in an upcoming concept release.
