Reminder Regarding Modification and Cancellation of Transaction Reports: Rule G-14
Rule Number:

Rule G-14

Executive Summary

The Municipal Securities Rulemaking Board (“MSRB”) reminds brokers, dealers and municipal securities dealers (collectively “dealers”) of the need to report municipal securities transactions accurately and to minimize the submission of modifications and cancellations to the Real-Time Transaction Reporting System (“RTRS”). Each transaction initially should be reported correctly to RTRS. Thereafter, only changes necessary to achieve accurate and complete transaction reporting should be submitted to RTRS. Changes should be rare since properly reported transactions should not need to be corrected.

Under Rule G-14, dealers are required to report all transactions to the MSRB and to report accurately and completely the information specified in the Rule G-14 RTRS Procedures (“Procedures”). Trades that are reported with errors affect the accuracy of the information published in price transparency reports as well as the audit trail information retained in the surveillance database.[1]

The MSRB has published notices to dealers reminding them of their obligation to report transactions correctly and to monitor error reports the MSRB sends them.[2]  Each trade should be reported correctly in the dealer’s initial submission of trade data to RTRS and, for inter-dealer trades, to the Real-time Trade Matching (“RTTM”) system as well. Changes should be rare since properly reported transactions should not need to be corrected. If, however, a transaction is reported with incorrect or missing attributes (such as price or capacity), the Procedures require the dealer to correct the report as soon as possible.[3]  When RTRS sends certain error messages to a dealer, the dealer is required to correct the trade report.[4] Dealers can make those corrections, or other necessary corrections in reported data, by modifying the trade report or by cancelling the report and submitting a correct replacement.[5] If it is necessary to modify a report, modification is preferred over cancellation and resubmission.[6]

Dealers should not change trade reports when the transaction attribute that changes is not required to be reported by MSRB or NSCC. For example, if only the account representative associated with a transaction changes, the report to the MSRB should not be changed, as this information is not required to be reported to the MSRB under Rule G-14. Dealers should take care that, if a modification or cancellation is submitted that is not responding to an RTRS error message, the dealer is correcting or cancelling an erroneous report.[7]

RTRS counts the number of modifications and cancellations submitted by each dealer. The MSRB provides statistics to the NASD and other enforcement agencies that measure dealer performance in modifying and cancelling transactions, as well as error rates of original submissions. Dealers that excessively modify or cancel trade reports will have above-average rates in these statistical reports. Dealers therefore should change trade reports only when appropriate to attain accurate and complete reporting under Rule G-14 and the Procedures.

Dealers can monitor their reporting of transactions in compliance with Rule G-14 in several ways. The MSRB currently provides information to dealers about their reporting performance. Any error detected by RTRS is reported back to the submitter by electronic message and is shown to the submitter and the executing dealer on the RTRS Web screen.[8] RTRS also sends e-mail error messages to dealers on request. The RTRS Web screen lists all trades cancelled by the dealer, under its Advanced Search feature. In addition, beginning in March 2005, the MSRB plans to make available to dealers the same statistics provided to the enforcement agencies, in a report entitled “G-12(f)/G-14 Compliance Data from RTRS.” This will be available monthly on the first Monday after the 15th of the month. A dealer’s report will include its statistics for the most recent full month and for the previous month.[9] It will also include summary statistics for the municipal securities industry so that the dealer can compare its performance to the industry’s. Further information about how a dealer can obtain its compliance statistics will be posted in March on the MSRB web site, www.msrb.org.

[4] Messages which indicate a trade report is “unsatisfactory” and which have an error code beginning with “U” require that the trade be modified or that it be cancelled and replaced. See “Specifications for Real-time Reporting of Municipal Securities Transactions,” especially the table and text after the table in section 2.9. This document is on www.msrb.org.

[5] Changes to inter-dealer trades are governed also by National Securities Clearing Corporation (“NSCC”) rules. See, e.g., “Interactive Messaging: NSCC Participant Specifications for Matching Input and Output” on www.nscc.com.

[6] Modification is preferred when changes are necessary because a modification is counted as a single change to a trade report. A cancellation and resubmission are counted as a change and (unless the resubmission is done within the original deadline for reporting the trade) also a late report of a trade. Methods for cancelling and modifying reports are described in Sections 1.3.3 and 2.9 of “Specifications for Real-time Reporting of Municipal Securities Transactions: Version 1.2” on www.msrb.org.

[7] Note that the MSRB does not require a dealer to report a change to the settlement date of a trade in  when-issued securities, if that is the only change.

Certain Inter-Dealer Transfers of Municipal Securities: Rules G-12(f)and G-14
Rule Number:

Rule G-12, Rule G-14

The MSRB has received questions about whether certain transfers of municipal securities between dealers to move securities between safekeeping locations are required to be reported to the MSRB Transaction Reporting System under Rule G-14, on transaction reporting.  When a transfer of municipal securities does not represent a purchase-sale transaction and is not required to be recorded on a dealer's books and records under MSRB Rule G-8 or SEC Rule 17a-3, such transfers should not be reported under Rule G-14 and a transaction report must not be sent to the MSRB. 

One scenario that has been brought to the MSRB's attention is when a dealer ("Dealer A") that self-clears inter-dealer transactions contracts with another dealer ("Dealer B") for the safekeeping and maintenance of customer accounts.  As part of this process, Dealer A transfers securities sold to customers to Dealer B for safekeeping.  The transfer of securities from Dealer A to Dealer B in this example is not an inter-dealer purchase-sale transaction and must not be reported to the MSRB as such.  However, Dealer A and Dealer B may wish to utilize the comparison and netting facilities of a registered clearing agency to effect the delivery of securities.   

In March 2004, the MSRB published a notice addressing the processing of certain inter-dealer transfers of securities that do not represent inter-dealer purchase-sale transactions through the automated comparison facilities of National Securities Clearing Corporation (NSCC).[1]  Since data sent to NSCC for comparison of an inter-dealer purchase-sale transaction also is sent to the MSRB for transaction reporting purposes, the March 2004 notice described use of the "B" indicator for identifying such data submissions relating to transfers of securities so that they are not confused with transaction reports between dealers that represent trades made through the comparison system.  Dealers should refer to the March 2004 notice if they chose to use the facilities of NSCC for such transfers to ensure that erroneous inter-dealer transaction reports are not sent to the MSRB Transaction Reporting System.[2]


[1] See MSRB Notice 2004-9, "Notice on Deliveries of Step Out Transactions Through the Automated Comparison System," March 3, 2004, on www.msrb.org.

[2] Note, however, that a different procedure will be used to effect inter-dealer transfers of securities, using the NSCC comparison system, and without reporting the transfer to the MSRB as a transaction when MSRB's Real-Time Transaction Reporting System goes into operation, currently planned for January 2005.

Transaction Reporting of Multiple Transactions Between Dealers in the Same Issue: Rules G-12(f) and G-14
Rule Number:

Rule G-12, Rule G-14

The MSRB has become aware of problems in transaction reporting as a result of dealers "bunching" certain inter-dealer transactions in the comparison system.  Recently, some dealers have reported the sum of two trades as one transaction in instances when two dealers effected two trades with each other in the same issue and at the same price.  When two transactions are effected, two transactions should be reflected in each dealer's books and records and two transactions are required to be reported to the MSRB.  The time of trade for each transaction also must accurately reflect the time at which a contractual commitment was formed for each quantity of securities.  For example, if Dealer A purchases $50,000 of a municipal issue at a price of par from Dealer B at 11:00 am and then purchases an additional $50,000 at par from Dealer B at 2:00 pm, two transactions are required to be reflected on each dealers' books and records and two transactions are required to be reported to the MSRB. 

Since the same inter-dealer trade record submitted for automated comparison under Rule G-12(f) also is used to satisfy the requirements of Rule G-14, on transaction reporting, each inter-dealer transaction should be submitted for automated comparison separately in order to comply with Rule G-14's requirement to report all transactions.  Failure to do so causes erroneous information concerning transaction size and time of trade to appear in the transparency reports published by the MSRB as well as in the audit trail used by regulators and enforcement agencies.  To the extent that dealers use the records generated by the comparison system for purposes of complying with MSRB Rule G-8, on recordkeeping, it may also create erroneous information as to the size of transactions effected or time of trade execution.
