SLB 12A

Date: June 22, 2001 (revised)

Summary: This staff legal bulletin sets forth the views of the Division of Market Regulation in response to frequently asked questions concerning Rule 11Ac1-5 under the Securities Exchange Act of 1934.

Supplementary Information: The statements in this legal bulletin represent the views of the staff of the Division of Market Regulation. This legal bulletin is not a rule, regulation, or statement of the Securities and Exchange Commission ("Commission"). Further, the Commission has neither approved nor disapproved its content.

Contact Person: For further information, please contact Daniel M. Gray, Senior Special Counsel, at (202) 942-4164, or Susie Cho, Attorney, at (202) 942-0748, Division of Market Regulation, Securities and Exchange Commission, 450 Fifth Street, N.W., Washington D.C. 20549-1001.

The Commission adopted the Rule in November 2000.1 It generally requires a "market center" (as defined in the Rule) that trades national market system securities to make available to the public monthly electronic reports that include uniform statistical measures of execution quality. The Rule directed the self-regulatory organizations ("SROs") that trade national market system securities to act jointly and submit to the Commission a new national market system plan establishing procedures for market centers to follow in making their monthly reports available to the public. The SROs submitted such a plan on February 20, 2001 ("Joint-SRO Plan"), and it has been approved by the Commission.2 A copy of the Joint-SRO Plan is attached as Appendix A.

The initial compliance date for the Rule was moved back by one month until May 1, 2001.3 In addition, the Commission has issued a temporary exemption from the reporting requirements of the Rule until July 31, 2001 for Nasdaq securities.4 Finally, the Commission recently issued an exemption with respect to any market center that is required to prepare a report that covers trading in May 2001.5 Under the exemption, such a market center is not required to make its May report publicly available on an Internet site, as specified in the Joint-SRO Plan. The market center must, however, prepare a May report internally and make it available for inspection and examination by the Commission staff. Reports that cover trading in June must be made publicly available on an Internet site by the end of July in accordance with the Joint-SRO Plan.

Since adoption of the Rule, the Division has received inquiries concerning the implementation and operation of the Rule. The Division is issuing this staff legal bulletin to address a variety of frequently asked questions. The following questions and answers do not necessarily contain a discussion of all the material considerations necessary to reach the conclusions stated. Consequently, these questions and answers are intended to provide general guidance, but the facts and circumstances relating to particular market centers may differ, and the staff notes that even slight variations may require different responses. The Commission is not bound by these statements and may interpret the Rule as it deems necessary or appropriate in the public interest or for the protection of investors.

In addition, these questions and answers are premised on several important assumptions. First, the discussions assume close familiarity with the text of the Rule and the Adopting Release, and we urge you to read carefully the Rule and Adopting Release. The responses are a complement to, and not a substitute for, these sources. Second, the terms used in this staff legal bulletin have the meanings set forth in the definitions of paragraph (a) of the Rule.

The Division may update these questions and answers periodically by issuing an updated staff legal bulletin. In each updated staff legal bulletin, the questions and answers with modified or new material since the last update will be marked as "modified" or "new."

Q: What format and procedures should market centers follow in preparing their monthly reports and making them available to the public?

A: The format of monthly reports and procedures for making them available to the public are spelled out in the Joint-SRO Plan, attached as Appendix A. In general, it requires market centers to make their monthly reports available in the form of electronic data files (standard, pipe-limited ASCII files). The Joint-SRO Plan also sets forth in detail the required contents of the electronic data file, including the identity and order of the 26 fields of information that the file must contain.

Attached as Appendix B is a table indicating how a market center's statistics could appear for a single security "A" in a report on trading for the month of May 2001. Appearing horizontally across the page (designated as F1, F2, F3 . . . F26) are the 26 required fields of information. A description of each of the fields may be found in paragraphs (a)(1) through (a)(26) of Section VI of the Joint-SRO Plan.

Appearing vertically down the page are 20 records - one reflecting each of the possible subcategories of order type (of which there are 5)6 and order size (of which there are 4)7 required for a single security. Sample statistics are provided in the table for the first record (representing market orders for 100-499 shares) to give a general idea of what a market center's statistics may look like. A full report would contain separate records for each individual national market system security upon which a market center must report. Although there potentially could be as many as 20 separate records for each individual security, Section VI(b) of the Joint-SRO Plan provides that no record need be displayed if a market center received no covered orders that fall within the particular subcategory of security/order type/order size.

The electronic data files containing market center reports must be made available for downloading (through FTP) without charge from an Internet site ("Download Site"). Under Section VIII of the Joint-SRO Plan, every market center will be responsible for making arrangements with an SRO to act as the market center's "Designated Participant." Designated Participants are responsible for assigning a unique market center identification code (which must be set forth in Field 2 of a market center's electronic data file)8 to each market center for which it acts as Designated Participant.

In addition, every market center must notify its Designated Participant of the hyperlink to the market center's Download Site. In turn, each Designated Participant will maintain an Internet site ("Link Site") that includes a comprehensive list of hyperlinks to the respective Download Sites for all of its market centers. In this way, anyone who wishes to download all market center reports for each month can be assured that, if they visit the Link Sites of all Designated Participants, they will find hyperlinks to files containing all market center reports.

Q: Does the Rule require every market center to make its monthly reports available to the public in a separate file on its own Internet site, or is it permissible for a market center to arrange with other entities (such as a vendor or a market center's SRO) for assistance in making the market center's reports available?

A: A market center need not make its reports available on its own Internet site. Market centers have the option to make arrangements with other entities to perform the functions necessary to make their reports available to the public. Nor must each market center's report be downloadable in a separate data file. Thus, for example, an SRO may make the monthly reports for all of its members available in a single file. Section VIII of the Joint-SRO Plan establishes procedures that will allow the public to determine the name of the file containing every market center's reports and the location where the file can be downloaded.

Q: Firm X acts both as an exchange specialist and as an OTC market maker. How should Firm X report under the Rule?

A: Firm X operates as two separate market centers and must report separately (with a separate market center identification code) on trading in each venue.

The definitions in paragraph (a) of the Rule set out the different types of market centers that must report under the Rule. The term "market center" is defined in paragraph (a)(14) as "any exchange market maker, OTC market maker, alternative trading system, national securities exchange, or national securities association." An "exchange market maker" is defined in paragraph (a)(9) of the Rule as "any member of a national securities exchange that is registered as a specialist or market maker pursuant to the rules of such exchange." An "OTC market maker" is defined in paragraph (a)(18) of the Rule as "any dealer that holds itself out as being willing to buy from and sell to its customers, or others, in the United States, a national market system security for its own account on a regular or continuous basis otherwise than on a national securities exchange in amounts of less than block size."

Accordingly, Firm X, because it acts both as an exchange specialist and as an OTC market maker, would be considered two separate market centers under the Rule and must report separately on its trading in each venue. The same result would hold if a firm acted as a specialist on two different exchanges. The Rule is intended, among other things, to provide investors and the public with order execution information that will assist them in making order routing decisions. Different exchanges have different trading rules and systems that can affect order execution quality, as do firms when they act as OTC market makers. It therefore is important that monthly reports under the Rule reflect these differences.

Q: Firm X is an integrated broker-dealer that acts as an OTC market maker in 500 national market system securities and also accepts orders in other national market system securities solely as agent for routing to other market centers for execution. In addition, Firm X sometimes receives orders in its 500 market maker stocks that, either because of specific customer instructions or the nature of the particular customer (for example, an advisory client), Firm X is required to route as agent to another market center for execution. How should Firm X report its activities under the Rule?

A: The Rule applies to broker-dealers insofar as they act as a "market center" with respect to orders received from other persons. Consequently, for orders in securities for which Firm X does not act as an OTC market maker, Firm X would not be acting as a market center in those securities and therefore need not report on orders in those securities that it receives as agent and routes elsewhere for execution.

Conversely, the orders that Firm X receives from any person in the 500 securities in which it acts as an OTC market maker (and therefore is a market center) generally must be included in Firm X's monthly reports, even if Firm X ultimately routes some of the orders to other market centers for execution. These orders would be reflected in the "shares executed at any other venue" statistic required by paragraph (b)(1)(i)(E) of the Rule and otherwise would be reported in exactly the same way as if the order were executed at Firm X.

If, however, Firm X receives orders in stocks for which it acts as an OTC market maker that Firm X is required to route as agent to another market center for execution (either because of specific customer instructions or the nature of the particular customer -- it is, for example, an advisory client), then Firm X would not act as a market center for these types of orders and need not include them in its monthly reports.

Q: The Rule's definition of "covered order" specifically excludes a number of types of orders for which the customer requests special handling and therefore are not covered by the Rule. Are there other types of orders that fall within the special handling exclusion, such as fill-or-kill and average price orders?

A: The definition of covered order in paragraph (a)(8) of the Rule does not specifically identify every type of order that may fall within the "special handling" exclusion. In general, any market or limit order for which the customer requests a type of handling that may preclude the order from being executed promptly at the current market price at the time of order receipt (subject only to a limit price) would qualify for the special handling exclusion and not be covered by the Rule. Accordingly, fill-or-kill orders are excluded because they must be executed only at their full size ("executed only at their full size" is one of the specific examples in the Rule of a special handling order). In addition, average price orders (understood as orders that are not intended to be executed promptly at the current market price at the time of order receipt but at an average price over a period of time) also would qualify as special handling orders and be excluded from the Rule.

Q: Is a market center required to report on orders that it receives "manually" -- otherwise than through automated systems?

A: Not now. The Commission has issued an exemption pursuant to paragraph (c) of the Rule that temporarily exempts orders received by a market center otherwise than through automated systems.9

Although market centers receive the overwhelming majority of their orders through automated systems, they also receive orders manually, particularly those for large sizes. Many of these orders may qualify for one of the "special handling" exclusions from the definition of "covered order" under paragraph (a)(8) of the Rule. Nevertheless, unless the necessary information is captured in automated systems, it would be quite difficult to include these orders in the required statistics or to efficiently demonstrate that a particular exclusion applies. The exemption of manually-received orders from the Rule is intended to facilitate timely compliance with the Rule until market centers have automated systems in place to capture all orders.10

Integrated broker-dealer firms, however, should be aware that the exemption only covers orders that are routed directly by manual means to the firm's trading desk. Orders received manually from brokerage customers, which are then input into an automated system for routing and execution would not be eligible for the exemption and would continue to be subject to the Rule. The time of receipt for such orders would be the time that the orders are captured in the automated system.11

In addition, this exemption is intended to facilitate compliance with the Rule for orders that currently are not captured in automated systems. Any change in order routing practices from automated to manual means to avoid reporting of orders under the Rule would be the basis for withdrawal of the exemption from that market center, and would raise serious questions with respect to a broker-dealer's obligation to obtain the best execution of its customers' orders.

Q: In several different contexts, the Rule requires reference to the consolidated best bid and offer ("Consolidated BBO") disseminated pursuant to an effective national market system plan. How should market centers report on orders whose statistics would be affected by a Consolidated BBO that is locked or crossed?

A: If the Consolidated BBO is locked (the best bid to buy equals the best offer to sell), the quotes still should be used for all purposes under the Rule. If the Consolidated BBO is crossed (the best bid to buy is higher the best offer to sell), a market center should follow the procedures set forth below.

The Rule requires reference to a Consolidated BBO in four different contexts: (1) classifying limit orders based on the Consolidated BBO at the time of order receipt into one of four categories defined in the Rule (marketable, inside-the-quote, at-the-quote, near-the-quote); (2) calculating the average effective spread for market and marketable limit orders based on the Consolidated BBO at the time of order receipt; (3) classifying executions of market and marketable limit orders as "with price improvement," "at the quote," or "outside the quote" based on the Consolidated BBO at the time of order receipt; and (4) calculating the average realized spread for all five types of orders defined in the Rule (market orders and the four types of limit orders) based on the Consolidated BBO five minutes after the time of order execution (as opposed to the time of order receipt).

When the Consolidated BBO is crossed for a significant period of time, it raises serious questions whether the quotes continue to provide a reliable benchmark for the statistical measures included in the Rule. The Commission therefore has exempted all orders from the Rule that would require reference to a Consolidated BBO that has been crossed for 30 seconds or more.12 In light of this exemption, market centers should follow the following procedure whenever a reference to the Consolidated BBO is necessary, whether at the time of order receipt or the time of order execution:

First, use the Consolidated BBO if the quotes are not crossed, or are locked.

Second, if the Consolidated BBO is crossed, reject the crossed quotes and use the next-in-time uncrossed Consolidated BBO if there has been less than 30 seconds between the last-in-time uncrossed Consolidated BBO and the next-in-time uncrossed Consolidated BBO.

Third, if there has been 30 seconds or more between the last-in-time uncrossed Consolidated BBO and the next-in-time uncrossed Consolidated BBO, the affected order is exempted from the Rule and must be excluded entirely from a market center's report (even if the crossed Consolidated BBO only affects a partial execution of the order).

The following examples illustrate how the foregoing procedure should apply:

Example 7-1: At 11:08:10 a.m.,13 a market center receives a limit order to buy 100 shares of Security A with a limit price of $20.75. The Consolidated BBO for Security A at the time of order receipt is $20.75 bid and $20.75 offer.

The locked quotes should be used. The order therefore would be classified as a "marketable limit order" under paragraph (a)(15) of the Rule because the limit price is equal to the consolidated best offer at the time of order receipt.14 The midpoint of the Consolidated BBO for purposes of calculating an effective spread for the execution is $20.75. If the buy order is executed at a price of $20.75, the execution would be classified as "at the quote" under paragraph (a)(10) of the Rule. If the buy order is executed at any price lower than $20.75, the execution would be classified as "with price improvement" under paragraph (a)(12) of the Rule. The calculation of a realized spread for the execution would be based on the midpoint of the Consolidated BBO five minutes after the time of order execution, so that the locked quotes at the time of order receipt would be irrelevant.

Example 7-2: At 2:47:20 p.m., a market center receives a market order to sell 500 shares of Security A. The Consolidated BBO for Security A at the time of order receipt is $55.40 bid and $55.30 offer. The time of the last uncrossed Consolidated BBO was 2:47:05 p.m. The next uncrossed Consolidated BBO is disseminated at 2:47:30 p.m. and is $55.35 bid and $55.35 offer. The market center should reject the crossed quotes at the time of order receipt and instead use the uncrossed quotes at 2:47:30 p.m. (even though they were locked) as the Consolidated BBO at the time of order receipt. The midpoint of the Consolidated BBO for purposes of calculating the effective spread for the order execution is $55.35. If the market order to sell is executed at a price higher than, equal to, or lower than $55.35, the execution will be classified, respectively, as "with price improvement, "at the quote," or "outside the quote."

Example 7-3: Same facts as Example 7-2 except that the next-in-time uncrossed Consolidated BBO after the time of order receipt is disseminated at 2:47:40 p.m. Because the period between the last-in-time uncrossed Consolidated BBO (2:47:05 p.m.) and the next-in-time uncrossed Consolidated BBO (2:47:40 p.m.) is 30 seconds or more, the market order to sell 500 shares of Security A is exempted from the Rule and must be excluded from the market center's monthly report.

Q: How should orders for a security be handled when they are received during regular trading hours, but trading in the security is halted at the market center either at the time of order receipt or shortly thereafter? Does the answer differ depending on whether the trading halt is a general regulatory halt or occurs solely at the particular market center that received the order?

A: The manner of reporting on orders under the Rule will be the same for all "announced" trading halts. To qualify as an "announced" trading halt, the halt must be either a general regulatory halt or a trading halt that is announced by a market center in accordance with all applicable regulatory rules. Orders that are received prior to and during the time of an announced trading halt should be handled in accordance with the following procedures.

First, all orders received during the period that trading is halted must be entirely excluded from a market center's monthly report. 15

Second, if an order was received less than five minutes prior to the trading halt and remains outstanding (in whole or in part) at the time of the trading halt, the entire order is exempted from the Rule16 and should be excluded from the market center's monthly report.

Third, for orders that are executed less than five minutes prior to the trading halt, the calculation of average realized spread should use the last Consolidated BBO disseminated prior to the time of the trading halt (analogous to the treatment of orders executed less than five minutes prior to the close of regular trading hours that is set forth in paragraph (a)(3) of the Rule).

Fourth, if an order was received five minutes or more prior to the trading halt and remains outstanding (in whole or in part) at the time of the trading halt, the order continues to be covered by the Rule; provided, however, that for executions that occur after the end of the trading halt, a market center may deduct the time period during which trading was halted from the calculations using the time of execution of the order.

The following examples illustrate how these foregoing procedures should apply:

Example 8-1: At 10:45:30 a.m., Market Center X halts trading in all securities because of a serious systems breakdown. It announces the trading halt in accordance with all applicable regulatory rules. At 11:25:30 a.m., Market Center X resumes trading in all securities. All orders received for execution by Market Center X from 10:45:30 a.m. until 11:25:30 a.m. are exempted from the Rule and must be excluded from Market Center X's monthly report.

Example 8-2: Same facts as Example 8-1, except that Market Center X receives a marketable limit order at 10:44:45 a.m. that is unexecuted at the time trading is halted 45 seconds later. The order is exempted from the Rule and must be excluded from Market Center X's monthly report.

Example 8-3: Same facts as Example 8-1, except that Market Center X receives a marketable limit order for 500 shares at 10:42:15 a.m. that receives a partial execution of 200 shares at 10:42:20, with the balance of 300 shares still unexecuted and outstanding at the time of the trading halt. The entire order is exempted from the Rule and must be excluded (including the 200-share execution) from Market Center X's monthly report.

Example 8-4: Same facts as Example 8-1, except that Market Center X receives a near-the-quote limit order at 10:38:15 a.m. that is unexecuted and outstanding at the time of the trading halt. At 11:28:05 a.m., after the end of the trading halt, the order is executed. Because the order was received more than five minutes before the trading halt, the order remains covered by the Rule, except that Market Center X may deduct the 40-minute period of the trading halt from the time of execution. The time of execution for non-marketable limit orders must only be reported in one of the five time buckets set forth in paragraphs (b)(1)(i)(F) through (J) of the Rule. Accordingly, the execution of the order would fall within the time bucket for order executions between 5 and 30 minutes after the time of order receipt (11:28:05 minus 10:38:15 minus 40 minutes).

Q: Must a market center report on commitments to trade that are received from other market centers pursuant to ITS Plan provisions?

A: Yes. Market centers are required to report under the Rule on commitments to trade received pursuant to the ITS Plan procedures. If a market center's handling of ITS commitments to trade differs materially from its handling of orders received through other mechanisms, it would be permissible to report on ITS activity as a separate market center (i.e., by obtaining a separate market center identification code pursuant to Section VIII of the Joint-SRO Plan for the market center's ITS activity).

Q: How should orders sent to Nasdaq's National Market Execution System ("SuperSOES") and through its SelectNet system be reported under the Rule?

A: In the original issuance of this staff legal bulletin, the Division addressed the application of the Rule to Nasdaq's Small Order Execution System ("SOES") and SelectNet, as they currently operate. It expressed the view that SOES, which delivers automatic executions for limited types of orders, is itself a market center for which Nasdaq must issue monthly reports. SelectNet, in contrast, is merely an order routing system that does not deliver automatic executions and is not a separate market center. Consequently, market centers that receive preferenced orders through SelectNet as an important means to access their displayed quotes must report on those orders under the Rule. Analogous to the treatment of ITS activity set forth in Question 9 above, if a market center's handling of SelectNet orders differs materially from its handling of orders received through other mechanisms, it would be permissible to report on SelectNet orders as a separate market center (i.e., by obtaining a separate market center identification code pursuant to Section VIII of the Proposed Plan for the market center's SelectNet activity).

The basis for the Division's view is the need for public information concerning the quality of executions provided through systems that offer general access to public quotes. One of the major objectives of the Rule is to address problems associated with market fragmentation. Systems that link market centers and provide an important means of access to their public quotes help address fragmentation and maintain the integrity of the public quote stream.17 These vital functions will be furthered by the public availability of information on the execution of orders routed through these systems.

Given Nasdaq's intention and belief that significant changes to SelectNet and SOES will be phased in by July 30, 2001, the Commission has issued exemptions and the Division has updated its interpretive guidance to reflect these changes.18 Most importantly, SuperSOES will replace SelectNet as the primary means of access to the public quotes of those market participants that accept automatic executions through SuperSOES ("SuperSOES Participants"), while SelectNet will remain an important means of general access to the quotes of firms that are not SuperSOES Participants.

Under Nasdaq rules, when SuperSOES is phased in for a security any SelectNet participant (with one exception discussed below) that wishes to preference a SuperSOES Participant through SelectNet may do so only by sending orders that are all-or-none ("AON") orders or minimum acceptable quantity ("MAQ") orders, either of which must be for a size that is at least 100 shares greater than the displayed amount of the preferenced participant's quoted size. Firms participating in SelectNet that are not SuperSOES Participants (such as an ECN), however, would continue to received preferenced orders through SelectNet for sizes equal to or less than their quoted size.

The Division views SuperSOES as a market center for which Nasdaq should issue monthly reports under the Rule.19 Consequently, the market centers against whose quotes SuperSOES delivers an automatic execution would not be required to report on these transactions. Importantly, however, a market center that first receives orders for execution and then chooses to route them away to SuperSOES for execution would continue to be required to report on these orders (including them, for example, in its monthly reports as "shares of covered orders executed at any other venue").

The Division believes that AON and MAQ orders routed through SelectNet to SuperSOES Participants for amounts at least 100 shares greater than the firm's displayed quote would not be covered orders, as defined in paragraph (a)(8) of the Rule. The definition excludes orders for which the customer requests special handling, including, but not limited to, orders to be executed only at their full size. Given the minimum size restrictions on AON and MAQ orders routed through SelectNet, thereby eliminating SelectNet as a general means to access the firm's public quote, the Division believes that they are appropriately excluded from covered orders. For market centers that are not SuperSOES Participants (such as an ECN), however, SelectNet will remain an important means of general access to their quotes. Accordingly, such market centers must report on SelectNet orders under the Rule (assuming they are not otherwise excluded from the definition of covered order).

The sole exception to the general rule that SuperSOES Participants will not receive preferenced orders through SelectNet for sizes equal to or less than their displayed quoted size relates to exchanges that trade Nasdaq securities pursuant to unlisted trading privileges that are not SuperSOES Participants ("UTP Exchanges"). Such UTP Exchanges may continue to use SelectNet to access the quotes of SuperSOES Participants. Given the ready access that automatic executions through SuperSOES will provide to the quotes of SuperSOES Participants, as well as the potentially significant costs associated with developing systems to report only on a small number of SelectNet orders from UTP Exchanges, the costs necessary to implement reporting on the orders would outweigh the benefits of the reported information. Consequently, the Commission has exempted from the definition of covered order in paragraph (a)(1) of the Rule the SelectNet preferenced orders routed to a SuperSOES Participant by a UTP Exchange.

In addition, in the event that the phase-in of SuperSOES, contrary to Nasdaq's current belief, is not completed by July 30, 2001, the Commission has exempted all SelectNet preferenced orders routed to SuperSOES Participants in Nasdaq securities for which the phase-in has not been completed.

Finally, SelectNet "broadcast" orders (which are not directed to any specific market center) would not be considered as received for execution by any market center and therefore should not be reported under the Rule.

Q: How should a market center report on partial executions and partial cancellations of orders under the Rule?

A: The Rule's statistics are designed to handle multiple partial executions and/or cancellations of an order. Immediately upon receipt by a market center, an order is permanently classified as falling within one of the 20 possible records relating to a subcategory of security/order type/order size. Thereafter, all executions and/or cancellations of the order will be included in the fields of information for that single record. Except for the field of information for total number of covered orders, all of the other fields of information required by the Rule are reported in terms of number of shares or share-weighted amounts. Consequently, each partial execution or cancellation can be reflected separately in the statistics.

Example 11-1: A market center receives a market order to buy 3000 shares of Security A at 3:30:00 p.m. The Consolidated BBO for Security A at the time of order receipt is $25.30 bid and $25.60 offer. The market center executes the order in three partial executions: 400 shares at $25.50 at 3:30:08 p.m., 1000 shares at $25.55 at 3:30:15 p.m., and 1600 shares at $25.60 at 3:31:02 p.m.

The market center would report on the 3000 share market order as follows. First, the order would be classified at the time of order receipt as falling within the record for Security A/market orders/2000 to 4999 shares. Thereafter, all information relating to the order will be included in one of the fields for that single record. Thus, 400 shares would fall within the field for shares executed from 0-9 seconds; 1000 shares would fall within the field for shares executed from 10-29 seconds; and the remaining 1600 shares would fall within the field for shares executed from 30-59 seconds.

Next, in calculating effective spreads, each partial execution would be treated separately and weighted according to the size of the partial execution. Thus, the effective spread for the first execution would be 10 cents: 25.50 minus 25.45 (the midpoint of the Consolidated BBO at the time of order receipt) multiplied by 2; the effective spread for the second execution would be 20 cents: 25.55 minus 25.45 multiplied by 2; and the effective spread for the final execution would be 30 cents: 25.60 minus 25.45 multiplied by 2. The 10 cent effective spread would be weighted by 400 shares, the 20 cent effective spread would be weighted by 1000 shares, and the 30 cent effective spread would be weighted by 1600 shares.

The remaining fields of information required for an order would be calculated in an analogous manner (e.g., a separate realized spread would be calculated for each partial execution).

Example 11-2: Same facts as Example 11-1, except that the final 1600 shares were cancelled by the customer prior to execution. All calculations discussed above under Example 11-1 would remain the same for the first two partial executions, but the final 1600 shares would now simply be included in the field of information for shares cancelled prior to execution.

Q: How should a market center report on orders received during regular trading hours, but that remain unexecuted and uncancelled at the end of regular trading hours on the day of order receipt?

A: Orders left unexecuted and uncancelled, in whole or in part, at the end of regular trading hours on the day of order receipt should be reflected in the market center's monthly report as having been received. No further information, however, should be reported concerning the unexecuted part of such orders, regardless of whether they are executed or cancelled in the hours, days, or weeks after the end of regular trading hours on the day of order receipt. In other words, a market center's statistical report should reflect the disposition of orders solely during regular trading hours on the day of order receipt, and each day begins with a clean slate of orders.

Example 12-1: A market center receives a 500 share at-the-quote limit order in Security A at 10:45:00 a.m. on April 30. At 10:45:08, 300 shares of the order are executed at the limit price. The remaining balance of 200 shares is left unexecuted at the end of regular trading hours on April 30. At 9:45:00 on the next day, May 1, the remaining 200 shares are executed.

The market center would reflect the order in its April report as follows. A single at-the-quote limit order for 500 shares would be reflected as having been received. The 300 share partial execution would be included in the field of information for shares executed at the market center and shares executed from 0-9 seconds after the time of order receipt. In addition, a realized spread would be calculated for the partial execution (the Rule does not require an effective spread and price improvement/disimprovement statistics for non-marketable limit orders). Nothing would be reported concerning the 200-share execution that occurred the following day, either in the market center's April report or in the market center's May report.

Q: How should a market center establish the time it receives an order when the order passes through various automated systems before it actually reaches the point at which it is executed? What about an integrated broker-dealer firm that initially receives orders from its brokerage customers?

A: A market center must assign a time of order receipt to its orders at the time they first are captured in an automated order handling system operated by, or on behalf of, the market center. For an integrated broker-dealer that receives orders from its brokerage customers, the time of order receipt is the time that it first captures these orders in the firm's automated order handling system.20

The time of order receipt is an essential element in calculating nearly every one of the Rule's statistics, such as assigning quotes as benchmarks for effective spread and price improvement statistics, as well as calculating speed of execution statistics. In the Adopting Release, the Commission emphasized that "it is critically important for market centers to assign a time of receipt (including seconds) to orders in a prompt, consistent, and non-manipulatory manner" and that "failure to meet the standard would be a serious violation of the Rule.21 Examples of such compliance concerns would include a market center queuing orders without immediately assigning a time stamp or a market center implementing preliminary selection criteria (e.g., to determine whether an order should be retained or routed to another market center for execution) prior to the time that the orders are marked as received and assigned a time of order receipt.

Q: The Rule requires market centers to record the time of order receipt "to the second." How should a market center assign a Consolidated BBO to an order that is received during the same second as one or more quote changes?

A: A market center may use any neutral algorithm to assign a Consolidated BBO to orders that are received during the same second as one or more quote changes. An algorithm is neutral if it chooses the quote in a consistent manner without reference to its impact on the market center's statistics. For example, it would not be appropriate for a market center to adopt an algorithm that assigns the intra-second Consolidated BBO with the highest offer to market orders to buy and the Consolidated BBO with the lowest bid to market orders to sell.

Q: Is it permissible for a market center to assign an execution time to orders when they are "stopped" or "guaranteed" an execution at no worse than a specific price and later assigned a specific execution price?

A: Yes. The statistical measures required by the Rule may be calculated using the guarantee time as the time of order execution, but only under the following conditions. First, the guarantee must be made pursuant to an SRO rule setting forth the standards for guaranteed or stopped executions. Second, the customer must be immediately informed of the guarantee and the guarantee price. Third, the guarantee must be final with no opportunity for rescission. Finally, the guarantee price must be no worse than the Consolidated BBO at the time of order receipt and for the full size of the order.

If guarantee time is used as the time of execution for an order, it must be used for all purposes under the Rule, including both the calculation of speed of execution statistics and the calculation of average realized spread, as defined in paragraph (a)(3) of the Rule.

Q: How should a market center report an order execution whose terms are subsequently adjusted or an order execution that is voided entirely?

A: If the terms of an order execution are adjusted or the execution is voided within a normal settlement cycle, the market center should report on the order in accordance with the terms of execution as they were finally received by the customer. Orders not adjusted or voided until after the normal settlement cycle should be reported as they were originally executed.

Example 16-1: A market center originally executes a market order to buy 200 shares of Security A at $15.80. The next day and prior to settlement, the market center receives an "exceptions report" indicating that the order should have been executed at a more favorable price to the customer. The market center adjusts the price to $15.70 and gives this price to the customer. The market center should report on the order based on a $15.70 execution price. All other reporting would remain the same (e.g., time of order execution).

Q: Should a market center's monthly report encompass all trading days that fall within a calendar month, as opposed to settlement days that fall within the calendar month?

A: A market center's monthly report should encompass all trading days that fall within the calendar month. Thus, orders received and executed on April 30 must be reported in a market center's April report, even though trades were not settled until May.

Q: The Adopting Release set forth a phase-in of compliance dates for the Rule in three stages. Is it permissible for a market center to begin reporting on all securities covered by the Rule on the initial compliance date?

A: Yes. Nothing prohibits a market center from reporting on all national market system securities covered by the Rule prior to the scheduled phase-in dates.

Q: How should a market center report under the Rule on an order that is received prior to dissemination of the first quotations for a trading day by the SRO with the primary listing for the security?

A: The Commission has exempted from the Rule any order that is received prior to the dissemination of the first firm, uncrossed quotations for a trading day by the primary listing SRO for the relevant security.22 The definition of covered order in paragraph (a)(8) of the Rule encompasses only those orders that are received during regular trading hours (beginning at 9:30 a.m. Eastern Time unless otherwise specified in accordance with the Joint-SRO Plan) and at a time when a Consolidated BBO is being disseminated. When the primary listing SRO has not yet disseminated its first quotations in a security, the remaining quotations that may be disseminated often can result in quoted spreads that vary significantly from the norm. The exemption will assure that such quoted spreads do not skew the execution quality statistics included in the monthly market center reports and reduce their comparability.

Q: How should a market center report under the Rule when the Consolidated BBO used to calculate the Rule's statistics appears to be erroneous?

A: Market centers should apply two standard filters to address a potentially erroneous Consolidated BBO (in addition to the procedure for handling crossed quotes addressed in Question 7 above). First, the Commission has exempted any order received during a time when the Consolidated BBO reflects a spread (the difference between the offer and the bid) that exceeds $1 plus 5% of the midpoint of the Consolidated BBO.23

Second, a market center should reject a potentially erroneous Consolidated BBO in calculating any of the Rule's statistics if both (1) the midpoint of such Consolidated BBO (the "variant BBO") varies by more than 20% from the midpoint of the immediately preceding Consolidated BBO (the "original BBO"), and (2) the midpoint of the next succeeding Consolidated BBO ("correcting BBO") reverts back to within 20% of the midpoint of the original BBO. In this case, the market center should use the correcting BBO for orders that otherwise would refer to the variant BBO. If, however, the midpoint of the correcting BBO does not revert back to within 20% of the midpoint of the original BBO, the market center should accept the variant BBO.

Q: Is it permissible for a market center to calculate its statistical measures of execution quality under the Rule based on the time that its systems receive the Consolidated BBO from the central processor for the applicable national market system plan, rather than the time that such processor assigns to the Consolidated BBO when it is disseminated?

A: No. Market centers must calculate their statistics based on the time that the central processor for the applicable national market system plan assigns to the Consolidated BBO when it is disseminated. One of the important objectives of the Rule is to generate execution quality statistics that are comparable among different market centers. Benchmarking the order executions of all market centers to a Consolidated BBO with a single time will further this objective.

Q: The Joint-SRO Plan for Rule 11Ac1-5 requires that certain statistics be carried out to either one or four decimal places. Should these statistics be rounded or truncated to such decimal place?

A: The statistics should be rounded to the appropriate decimal place, with a "5" rounded up.

Q: How should a market center report under the Rule on an order that is modified by the customer after submission, such as when the customer changes the limit price on a limit order, removes the stop price on a stop order, or removes a special handling instruction?

A: Except for a reduction in the size of an order (addressed in Question 11 above as a partial cancellation of an order), order modifications should be reported as a cancellation of the original order and a submission of a new order as replacement for the cancelled order. A market center should report on the replacement order (assuming it falls within the definition of covered order) just as it would any other new order. An adjusted or voided order execution is addressed is Question 16 above.

Q: How should a market center report under the Rule on an order that it receives and executes as riskless principal?

A: The market center executing an order as riskless principal should reflect the order in its monthly report as executed at such market center (not at another venue), using the time that the order was executed at such market center.

Question 25: Exemption for Inactively Traded Securities (new)

Q: Is a market center required to report on orders in all national market system securities, even those that are inactively traded?

A: No. The Commission has exempted orders in national market system securities that are inactively traded.24 The exemption covers any national market system security that did not average more than five reported transactions per trading day, as disseminated pursuant to an effective transaction reporting plan, for each of the preceding six months (or such shorter time that the security has been designated a national market system security). An inactive security will lose its exemption only after its average daily reported transactions have exceeded five for each of the preceding six months. Orders in exempted securities need not be included in a market center's monthly report, but a market center is free to include them if it chooses to do so.

Q: Are any small market centers exempt from the Rule?

A: The Commission has exempted from the Rule certain small market centers that do not focus their business on the most actively traded securities.25 Small market centers often may be significant sources of liquidity in the securities of small and medium companies, but have fewer transactions than large market centers over which to distribute the cost of generating the monthly execution quality reports. The Commission therefore is concerned that the costs of compliance for small market centers, as well as the potential costs if small market centers cease supplying liquidity, potentially could outweigh the benefits of their monthly reports. If a small market center chooses, however, to focus a significant part of its business in very actively traded securities, it should compete on the same terms as larger market centers that trade those securities.

The exemption covers any market center that reported fewer than 200 transactions per trading day on average over the preceding six month period in securities that are covered by the Rule (that is, national market system securities that do not qualify for the inactively traded security exemption), but only if more than 90% of such transactions were in securities that are not included in the Nasdaq-100 Index or the S&P 500 Composite Stock Price Index. Once a market center's average daily reported transactions for the preceding six-month period reach 200, or the percentage of its reported transactions in Nasdaq-100 and S&P 500 securities reaches 10% or greater for the preceding six-month period, the market center would cease to qualify for the exemption. The market center then would be required to begin collecting the requisite order data for the following full month and make its monthly report for that month publicly available by the end of the next month thereafter. For example, if the market center ceased to qualify for the exemption based on trading during the six-month period from January through June, the market center must begin collecting order data for August and make its monthly report (covering August) publicly available by the end of September.

A broker-dealer that routes orders to a market center that does not generate monthly execution quality reports continues to have a duty to monitor the quality of executions received to obtain the best execution of those orders.

Q: Is there any maximum size restriction on the orders that must be included in a market center's monthly report?

A: Yes. The Commission has exempted from the Rule any order with a size of 10,000 shares or greater.26 One of the primary objectives of the Rule is to generate statistical measures of execution quality that provide a fair and useful basis for comparisons among different market centers. Large orders have been excluded to assure greater comparability of statistics in the largest size category of 5000 or greater shares.

(b) Records

Files shall have separate records for each combination of security, order type, and order size by which a market center must categorize its report under the Rule (a maximum of 20 records for each individual security).2 The end of each record shall be designated by a carriage return line feed. If there are no orders on which a market center must report during a month for a specific combination of security, order type, and order size, no record for such combination need be displayed. If there is no data for a particular field within a record (e.g., the Rule does not require such information for inside-the-quote limit orders, at-the-quote limit orders, and near-the-quote limit orders), the field shall be left empty.

VII. Internet Sites for Downloading Market Center Files

A market center shall make its compressed files available for downloading (via FTP) at a single page on an Internet site that is free of charge and readily accessible to the public.3 A market center shall make available on such page the files containing at least the three most recent monthly reports of the market center.

VIII. Functions of Designated Participant

Each market center shall be responsible for arranging with a single Participant to act as the market center's Designated Participant.4 The functions of a Designated Participant are as follows.

(a) Assignment of Market Center and File Identification Codes

A Designated Participant shall assign a unique market center identification code to each market center for which it acts as Designated Participant. If an individual market center's report will be included in a file that contains only that market center's report, the file identification code for the file shall be the same as the market center identification code. If an individual market center's report will be included in a file that contains any additional market center's report (e.g., if the reports for all of an exchange's specialists are included in a single file), the Designated Participant also shall assign a separate file identification code for such file. All Designated Participants will act jointly to assure that no market center or file is assigned a code that previously has been assigned (e.g., by circulating advance notice to all Participants of codes that have been assigned).

(b) Maintenance of Market Center Identification Files

A Designated Participant shall create and maintain a market center identification file (in standard, pipe-delimited ("|") ASCII format) for each calendar month. Such file shall contain fields setting forth, in order, (A) the identification code for the Designated Participant (as set forth in Section VI(a)(1) of the Plan); (B) all market center identification codes that the Designated Participant has assigned for the month, (C) the full name of the market center (in upper case), and (D) the file identification code applicable to each market center (if different from the market center identification code). A Designated Participant shall make at least the three most recent market center identification files available for downloading (via FTP) on an Internet site that is free of charge and easily accessible to the public.

(c) Maintenance of Internet Site with Links to Download Sites

A market center shall notify its Designated Participant of the hyperlink to the location where the market center's files can be downloaded in accordance with Section VII of the Plan. A Designated Participant shall maintain a comprehensive list of the hyperlinks provided by its market centers at the same location at which market center identification files can be downloaded in accordance with Section VIII(b) of the Plan. As a result, anyone who wishes to download all files for a month can be assured that, if they visit the Internet sites of all Participants, they will find hyperlinks to all files for the month.

(d) Change of Designated Participant

A market center may change the identity of its Designated Participant only by arranging with another Participant to act as a replacement. The Participant that has agreed to act as a replacement Designated Participant shall provide written notice of the change to all other Participants, as well as make such notice available on the Internet site maintained by the replacement Designated Participant under Section VIII(b) of the Plan. The notice shall specify both the past and new market center identification code and file identification code for the market center, or state that the codes have not changed. The change shall not be effective until 30 days after the date of the written notice.

IX. Internet References to Information Required by Rule

When referring to information on Internet sites that the Rule requires to be made available to the public, market centers and Designated Participants shall use the phrase "Disclosure of SEC-Required Order Execution Information."

X. Specifying Regular Trading Hours Under the Rule

With respect to the meaning of the term "regular trading hours" under paragraph (a)(19) of the Rule, the Participant who maintains the primary listing for a national market system security shall specify the regular trading hours for such security if they are to be other than the time between 9:30 a.m. and 4:00 p.m. Eastern Time. To effect a specification of regular trading hours under this Section X, a Participant shall submit a proposed rule change to the SEC under Section 19 of the Exchange Act. A Participant may specify as regular trading hours for a security only those times when the Participant itself is trading the security.

XI. Withdrawal from Plan

If a Participant ceases to be subject to the Rule or obtains SEC approval for another means of complying with the Rule, such Participant may withdraw from the Plan at any time on not less than 30 days' prior written notice to each of the other Participants. At such time, the withdrawing Participant shall have no further rights or obligations under the Plan.

XII. Counterparts and Signatures

The Plan may be executed in any number of counterparts, no one of which need contain all signatures of all Participants, and as many of such counterparts as shall together contain all such signatures shall constitute one and the same instrument.

IN WITNESS THEREOF, this Plan has been executed as of the 20th day of February 2001 by each of the parties hereto.
