I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend Exchange Rule 1600 (New York Block 
Exchange\SM\) (``NYBX\SM\'' or the ``Facility'') to provide for 
simultaneous routing, rather than sequential routing as the Facility 
currently operates, of appropriate volume from an NYBX order to attempt 
to execute simultaneously against all available contra side liquidity 
within the limit price of the order that is revealed on the initial 
market evaluation, whether that liquidity (1) Is in the NYSE Display 
Book[supreg] (``DBK''), displayed and undisplayed, (2) is in the 
Facility, (3) consists of top-of-book contra side quotations displayed 
on other automated trading centers that must be routed to in order to 
avoid potential trade throughs (in compliance with Regulation NMS) or 
(4) consists of top-of-book contra side quotations displayed on other 
automated trading centers where no potential trade through is involved 
and Regulation NMS does not require routing. There will no longer be an 
initial routing of the full amount of the order (less any shares routed 
to other automated trading centers to comply with Regulation NMS) to 
the DBK in the hope that there will be some additional volume executed 
(over and above the displayed and undisplayed contra side liquidity in 
the DBK) against available contra side interest, if any, in the Capital 
Commitment Schedule (``CCS'') of the Designated Market Maker provided 
for in NYSE Rule 1000(d)(i). The text of the proposed rule change is 
available at the Exchange's principal office, the Commission's Public 
Reference Room, and the Exchange's Web site at http://www.nyse.com.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the self-regulatory organization 
included statements concerning the purpose of, and basis for, the 
proposed rule change and discussed any comments it received on the 
proposed rule change. The text of those statements may be examined at 
the places specified in Item IV below. The Exchange has prepared 
summaries, set forth in sections A, B, and C below, of the most 
significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to amend Exchange Rule 1600 (New York Block 
Exchange\SM\) to provide for simultaneous routing, rather than 
sequential routing as the facility currently operates, of appropriate 
volume from an NYBX order to attempt to execute simultaneously against 
all available contra side liquidity within the limit price of the order 
that is revealed on the initial market evaluation, whether that 
liquidity (1) Is in the DBK, displayed and undisplayed, (2) is in the 
Facility, (3) consists of top-of-book contra side quotations displayed 
on other automated trading centers that must be routed to in order to 
avoid potential trade throughs (in compliance with Regulation NMS) or 
(4) consists of top-of-book contra side quotations displayed on other 
automated trading centers where no potential trade through is involved 
and Regulation NMS does not require routing. The following is a 
description of how the NYBX Facility currently operates, complete with 
examples, followed by a description of the ``Proposed Change in the 
Process,'' also with examples.
Current Operation of the Facility
    As currently provided in NYSE Rule 1600, an order in the NYBX 
Facility interacts with contra side liquidity in the DBK and the 
Facility itself through a series of separate transactions that may 
involve the order moving sequentially from one price level to another 
(all within the limit price of the order) and/or back and forth between 
the Facility and the DBK. In addition, if an NYBX order would execute 
in the DBK or in the Facility at a price that may potentially trade 
through a protected quotation of another automated trading center(s), 
applicable volume from the order will be routed immediately to such 
automated trading center(s) to assure compliance with Regulation NMS. 
Further, when contra side liquidity is available in the DBK at prices 
that are within the limit price of the NYBX order, the full amount of 
the order (less any shares routed to other automated trading centers to 
comply with Regulation NMS) is sent to the DBK in the hope that, in 
addition to execution with the displayed and undisplayed contra side 
liquidity in the DBK at the particular price, there will be some 
additional execution with available contra side interest, if any, in 
the CCS of the Designated Market Maker.
    As the execution of the order proceeds, the Facility reevaluates 
the market at various points to check for updated market data and 
adjusts the routing of the remaining portion of the order accordingly. 
Finally, after all available executions in the DBK and the Facility 
have taken place, including the routing of appropriate volume to other 
automated trading centers to prevent trade throughs of protected 
quotations, any remaining portion of the order will be routed away for 
execution with all remaining available top-of-book contra side 
quotations within the limit price of the order displayed by other 
automated trading centers even though not required by Regulation NMS.
    The following examples demonstrate how NYBX orders are currently 
processed prior to implementation of the proposed amendment. In the 
examples, ``MTV'' stands for the optional, user-defined Minimum 
Triggering Volume Quantity of an NYBX order provided for in NYSE Rule 
1600.

NYBX Market Evaluation

    NYBX (Sell orders):

5000 shares @ 21.00 (MTV = 100)
5000 shares @ 22.00 (MTV = 100)

    DBK (Sell orders):

1000 shares @ 21.00 (hidden)
1000 shares @ 22.00
1000 shares @ 23.00

    CHX (Sell orders):

1000 shares @ 21.00

    BATS (Sell orders):

1000 shares @ 22.00

Scenario A: NYBX Buy order for 5000 shares at 21.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 5000 shares routed to DBK at 21.00 and 1000 are executed at 
21.00.
    2. 4000 shares remain and are sent back to NYBX at 21.00.
    3. Verify no market data updates.
    4. 4000 shares execute in NYBX at 21.00.
    The full amount of the above order is initially routed to DBK due 
to the possibility of interaction with CCS interest. Note that no 
orders were routed to other automated trading centers because (i) there 
were no potential trade throughs that would violate Regulation

[[Page 58458]]

NMS and (ii) DBK and NYBX had priority for executions at 21.00 and 
there were no shares left from the order to execute at that price on 
CHX.

Scenario B: NYBX Buy order for 6500 shares at 21.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 6500 shares routed to DBK at 21.00 and 1000 are executed at 
21.00.
    2. 5500 shares remain and are sent back to NYBX at 21.00.
    3. Verify no market data updates.
    4. 5000 shares execute in NYBX at 21.00.
    5. Verify no market data updates.
    6. 500 shares routed to CHX at 21.00 and all are executed at 21.00.
    Again, the full amount of the order is initially routed to DBK and 
no orders are initially routed to other automated trading centers 
because there were no potential trade throughs that would violate 
Regulation NMS. However, shares are routed to CHX at the end of the 
sequence because all interest at 21.00 in both DBK and NYBX is 
exhausted and additional shares at that price are available on CHX even 
though Regulation NMS does not require shares to be routed there.

Scenario C: NYBX Buy order for 13500 shares at 22.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to CHX at 21.00 (Reg. NMS) and all are 
executed at 21.00. 12500 shares simultaneously routed to DBK at 21.00 
and 1000 are executed at 21.00.
    2. 11500 shares remain and are sent back to NYBX at 21.00.
    3. Verify no market data updates.
    4. 5000 shares execute in NYBX at 21.00.
    5. Verify no market data updates.
    6. 6500 shares remain and are routed to DBK at 22.00 and 1000 are 
executed at 22.00.
    7. 5500 shares remain and are sent back to NYBX at 22.00.
    8. Verify no market data updates.
    9. 5000 shares execute in NYBX at 22.00.
    10. Verify no market data updates.
    11. 500 shares routed to BATS at 22.00 and all are executed at 
22.00.
    In Scenario C, 1000 shares are initially routed to CHX at 21.00 to 
eliminate the potential of a trade through of this protected quotation 
(since the size and price limit of the order mean that contra side 
liquidity in the DBK and the Facility at 22.00 will be executed 
against) that is prohibited by Regulation NMS. The full amount of the 
remaining portion of the order is simultaneously routed to the DBK at 
21.00 even though only 1000 shares are available there at that price, 
because of the potential to interact with CCS interest. Later in the 
sequence of events, the full amount of the remaining order at that 
point (6500 shares) is routed to the DBK at 22.00 for the same reason, 
even though only 1000 shares are available there at that price. At the 
end of the sequence, the routing of 500 shares to BATS at 22.00 is not 
for the purpose of compliance with Regulation NMS (since no executions 
at a higher price will be triggered by the size and price limit of this 
order), but is made to access additional top-of-book contra side 
liquidity at another automated market center because no additional 
liquidity at that price is available in either the DBK or the Facility.

Scenario D: NYBX Buy order for 14500 shares at 23.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to CHX at 21.00 (Reg. NMS) and all are 
executed at 21.00. 1000 shares routed to BATS at 22.00 (Reg. NMS) and 
all are executed at 22.00. 12500 shares simultaneously routed to DBK at 
21.00 and 1000 are executed at 21.00.
    2. 11500 shares remain and are sent back to NYBX at 21.00.
    3. Verify no market data updates.
    4. 5000 shares execute in NYBX at 21.00.
    5. Verify no market data updates.
    6. 6500 shares remain and are routed to DBK at 22.00 and 1000 are 
executed at 22.00.
    7. 5500 shares remain and are sent back to NYBX at 22.00.
    8. Verify no market data updates.
    9. 5000 shares execute in NYBX at 22.00.
    10. Verify no market data updates.
    11. 500 shares routed to DBK at 23.00 and all are executed at 
23.00.
    Scenario D is very similar to Scenario C, except that the increase 
in order size and the increase in the limit price to 23.00 create a 
potential trade through at 23.00 in the DBK of the 22.00 protected 
quotation at BATS. Consequently, in addition to the 1000 shares that 
are initially routed to CHX at 21.00 to eliminate the potential for a 
trade through of that protected quotation that is prohibited by 
Regulation NMS, an additional 1000 shares are initially routed to BATS 
at 22.00 to eliminate the potential for a trade through of that 
protected quotation as well. The remaining execution sequence is the 
same as Scenario C except that the final 500 shares of the order are 
routed to the DBK and executed at 23.00 because all lower contra side 
prices in the market have been executed against.
Proposed Change in the Process
    In practice, the fact that the NYBX order proceeds through a series 
of steps that take place sequentially rather than simultaneously 
results in the disappearance or the adjustment of a substantial portion 
of the available contra side liquidity that shows up on the initial 
market evaluation, before the NYBX order is able to execute against 
that liquidity. Consequently, the purpose of the proposed amendment is 
to capture a higher percentage of the available contra side liquidity 
by attempting to execute simultaneously against all such liquidity 
within the limit price of the order that is revealed on the initial 
market evaluation, whether that liquidity (1) Is in the DBK (displayed 
and undisplayed), (2) is in the NYBX or (3) consists of top-of-book 
contra side quotations displayed on other automated trading centers. 
The initial portion of the order routed to the DBK will no longer be 
oversized in the hope of interacting with CCS interest, but will be 
sized based on the total amount of displayed and undisplayed contra 
side liquidity in the DBK that is available for execution within the 
limit price of the order. The same principle (no oversizing) will 
continue to be applicable to portions of the order that attempt to 
execute against available contra side interest in the Facility and 
against such interest that is displayed on other automated trading 
centers.
    As is the case with respect to the current operation of the 
Facility and in compliance with Regulation NMS, applicable volume will 
be routed immediately to execute against all protected quotations of 
other automated trading centers that may potentially be traded through 
by the NYBX order. However, the routing of applicable volume to other 
automated trading centers for execution against available contra side 
top-of-book quotations displayed by such markets where no potential 
trade through is involved will no longer be delayed until the order has 
executed with all available contra side liquidity in the DBK and the 
Facility. Instead, such volume will be routed out at the same time that 
other portions of the order attempt to execute against available contra 
side liquidity in the Facility or are routed for execution to the DBK 
or to other automated trading centers in compliance with Regulation 
NMS.
    In a situation in which the size of the NYBX order is less than the 
total available contra side liquidity that is potentially executable 
within the limit

[[Page 58459]]

price in the Facility and the DBK and at the top-of-book at other 
automated trading centers, the ``tie breaker'' rules for routing 
decision purposes will provide that (i) an execution in the DBK will 
have priority over an execution at the same price in the Facility or on 
another automated trading center, and (ii) an execution in the Facility 
will have priority over an execution at the same price on another 
automated trading center.
    The following examples demonstrate how NYBX orders will be 
processed under the proposed amendment. Assume the same NYBX initial 
market evaluation as above and the same four scenarios.

Scenario A: NYBX Buy order for 5000 shares at 21.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to DBK at 21.00 and all are executed at 21.00 
4000 shares simultaneously executed in NYBX at 21.00
    In Scenario A, no shares are routed to other automated trading 
centers because (i) there are no potential trade throughs for this 
price limit and order volume, and (ii) executions at 21.00 in DBK and 
NYBX at 21.00 have priority over executions at CHX at the same price. 
Even though the entire 5000 shares could execute within NYBX at 21.00 
with no routing necessary, 1000 shares are routed to the DBK to execute 
against contra side liquidity there at the same price because 
executions in DBK have priority over executions in NYBX. Unlike the 
current process, none of the routings to the DBK will be oversized 
(i.e., the number of shares routed will not exceed the displayed and 
undisplayed interest in the DBK at a given price). Therefore, only 1000 
shares will be initially routed to the DBK instead of the full order 
size of 5000 shares. Note that everything in Scenario A takes place 
simultaneously under the proposed amendment, compared to four 
sequential steps as the Facility currently operates.

Scenario B: NYBX Buy order for 6500 shares at 21.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to DBK at 21.00 and all are executed at 
21.00. 5000 shares simultaneously execute in NYBX at 21.00. 500 shares 
simultaneously routed to CHX at 21.00 and all are executed at 21.00.
    Again, only the amount of the displayed and undisplayed interest in 
the DBK is routed to the DBK, and no orders are routed to other 
automated trading centers for Regulation NMS compliance purposes (since 
there are no potential trade throughs that would violate Regulation 
NMS). However, shares are routed to CHX because all interest at 21.00 
in both DBK and NYBX will be executed against by the order, and 
additional shares at that price are available on CHX even though 
Regulation NMS does not require shares to be routed there for 
execution. Note that everything in Scenario B takes place 
simultaneously under the proposed amendment, compared to six sequential 
steps as the Facility currently operates.

Scenario C: NYBX Buy order for 13500 shares at 22.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to CHX at 21.00 (Reg. NMS) and all are 
executed at 21.00. 1000 shares simultaneously routed to DBK at 21.00 
and all are executed at 21.00. 5000 shares simultaneously execute in 
NYBX at 21.00. 1000 shares simultaneously routed to DBK at 22.00 and 
all are executed at 22.00. 5000 shares simultaneously execute in NYBX 
at 22.00. 500 shares simultaneously routed to BATS at 22.00 and all are 
executed at 22.00.
    In Scenario C, 1000 shares are routed to CHX at 21.00 to eliminate 
the potential of a trade through at 22.00 of this protected quotation 
(since the size and price limit of the order mean that contra side 
liquidity in the DBK and the Facility at 22.00 will be executed 
against) that is prohibited by Regulation NMS. The simultaneous routing 
of 500 shares to BATS at 22.00 is not for the purpose of compliance 
with Regulation NMS (since no executions at a higher price will be 
triggered by the size and price limit of this order), but is made to 
access additional top-of-book contra side liquidity at another 
automated market center because no additional liquidity at that price 
is available in either the DBK or the Facility. As before, only the 
amount of the displayed and undisplayed interest in the DBK is routed 
to the DBK. Note that everything in Scenario C takes place 
simultaneously under the proposed amendment, compared to eleven 
sequential steps as the Facility currently operates.

Scenario D: NYBX Buy order for 14500 shares at 23.00 (MTV = 100 shares)

    Results (each number below represents a separate step):
    1. 1000 shares routed to CHX at 21.00 (Reg. NMS) and all are 
executed at 21.00. 1000 shares simultaneously routed to BATS at 22.00 
(Reg. NMS) and all are executed at 22.00. 1000 shares simultaneously 
routed to DBK at 21.00 and all are executed at 21.00. 5000 shares 
simultaneously execute in NYBX at 21.00. 1000 shares simultaneously 
routed to DBK at 22.00 and all are executed at 22.00. 5000 shares 
simultaneously execute in NYBX at 22.00. 500 shares simultaneously 
routed to DBK at 23.00 and all are executed at 23.00.
    Scenario D is very similar to Scenario C, except that the increase 
in order size and the increase in the limit price to 23.00 mean that a 
full 1000 shares also need to be routed to BATS at 22.00 to eliminate 
the potential for a trade through in the DBK at 23.00 of that protected 
quotation in violation of Regulation NMS. Consequently, in addition to 
the 1000 shares that are initially routed to CHX at 21.00 to eliminate 
the potential for a trade through of that protected quotation that is 
prohibited by Regulation NMS, an additional 1000 shares are 
simultaneously routed to BATS at 22.00 to eliminate the potential for a 
trade through of that protected quotation as well. Scenario D also 
differs from Scenario C in that the final routing to DBK is against a 
portion of the available contra side liquidity there at 23.00, since 
all lower contra side prices in the market have been executed against. 
Note that everything in Scenario D takes place simultaneously under the 
proposed amendment, compared to eleven sequential steps as the Facility 
currently operates.
2. Statutory Basis
    The proposed rule change is consistent with Section 6(b) \3\ of the 
Securities Exchange Act of 1934 (the ``Act''), in general, and furthers 
the objectives of Section 6(b)(5) \4\ in particular in that it is 
designed to prevent fraudulent and manipulative acts and practices, to 
promote just and equitable principles of trade, to foster cooperation 
and coordination with persons engaged in facilitating transactions in 
securities, to remove impediments to and perfect the mechanism of a 
free and open market and a national market system and, in general, to 
protect investors and the public interest. More specifically, the 
Exchange believes that the proposed rule change will improve the 
quality of the market and the outcomes for investors by capturing a 
higher percentage of the available contra side liquidity through 
attempting to execute

[[Page 58460]]

simultaneously against all such liquidity within the limit price of the 
order that is revealed on the initial market evaluation, thereby 
increasing the probability that a large order placed in the Facility 
will achieve a complete and timely fill. The proposed rule change will 
thereby contribute to perfecting the mechanism of a free and open 
market and a national market system and is also consistent with the 
protection of investors and the public interest.
