MSRB NOTICE 2012-51 (OCTOBER 9, 2012)


As previously announced, effective November 5, 2012, brokers, dealers and municipal securities dealers (collectively “dealers”) must begin reporting the contractual dollar price at which an inter-dealer transaction was executed,  in addition to the information currently reported.[1]  All dealers that report inter-dealer transactions to the MSRB Real-Time Transaction Reporting System (“RTRS”) will need to make system and/or procedural changes to prepare for this change.


MSRB Rule G-14 requires dealers to report information about each purchase and sale transaction effected in municipal securities to RTRS.  Inter-dealer transaction reporting is accomplished by both the purchasing and selling dealers submitting information about the transaction to the Depository Trust and Clearing Corporation’s Real-Time Trade Matching System (RTTM).  Information submitted to RTTM is forwarded to RTRS for trade reporting.  For most inter-dealer transactions, dealers report final money, par amount and accrued interest to RTTM – as opposed to a dollar price and yield[2] as is done for customer trades – and RTRS computes a dollar price from these values for inter-dealer transaction price dissemination.

The information reported for inter-dealer transactions also is used by DTCC for purposes of clearance and settlement, and DTCC procedures require dealers to report par value as an expression of the number of bonds traded as opposed to the actual par amount traded.  If the par value of a security is no longer a $1,000 multiple because, for example, the issuer has prepaid a portion of the principal on a security on a pro rata basis, dealers continue to report for inter-dealer transactions par value expressed as the number of bonds (i.e. ten bonds would be reported as $10,000 par value).  Transactions between dealers in this security would result in erroneous RTRS-calculated dollar prices since the final money reported by the dealers would be based on a transaction in a security for which each bond costs less than $1,000.[3]

Since MSRB transaction reporting for inter-dealer transactions began in 1994, a very small portion of inter-dealer transactions have been in securities with a non-standard $1,000 par multiple.[4]  However, primarily since many Build America Bonds issued in recent years included partial call features with a pro-rata redemption provision, there is a likelihood that many more securities may contain par values that are no longer $1,000 multiples.  In addition, there have been press reports that more securities may be issued in nontraditional denominations, such as securities issued in $25 par amounts similar to preferred stock and other “mini bonds” with sub-$1,000 principal values.

To ensure that the dollar price disseminated by RTRS for inter-dealer transactions remains accurate and to minimize the impact on dealer operations as well as the clearance and settlement use of the data submitted by DTCC, dealers will be required to report – in addition to the information currently reported for inter-dealer transactions – the contractual dollar price at which the transaction was executed.[5]


MSRB and DTCC have coordinated system changes to RTRS and RTTM to add the contractual dollar price as a new reporting data field on inter-dealer transactions.  In January 23, 2012, DTCC published technical specifications detailing the new data field that will be used by dealers to report the contractual dollar price, named the “Regulatory Dollar Price” field, on inter-dealer transactions.[6]  An updated RTRS technical specifications document that describes this and other changes that become effective November 5, 2012 is provided below and also is available on the trade data page of the Market Disclosures and Data section of the MSRB website.


On June 20, 2012, MSRB and DTCC made a test environment available to dealers and their agents for making test submissions of inter-dealer trades to RTRS.  MSRB and DTCC also have suggested test cases accessible from the link below that can be used to gauge dealer readiness for the November 5, 2012 changes.

[2]  Dollar price and yield on customer transactions are required to be computed in the same manner as required under MSRB Rule G-15(a), on customer confirmations.  Accordingly, from the transaction dollar price, dealers report yield calculated to the lower of an in-whole call feature or maturity.

[3]  For example, if an issuer has prepaid 50% of the principal on a $1,000 denominated security, each bond would cost $500 so a transaction of 10 bonds at “par” would be reported with a par value of $10,000 and final money of $5000 resulting in an RTRS-computed dollar price of $50.  This anomaly only occurs on inter-dealer transactions since customer transactions are reported with a dollar price and yield.  In this example, the dollar price on a customer transaction in this security would be reported as $100, or 100% of the principal amount.

[4]  Historically, this problem primarily has been limited to transactions in certain municipal collateralized mortgage obligations.

[5]  For data quality purposes, RTRS will compare the buy and sell-side contractual dollar prices and return errors to dealers in the event of a material difference between the two reported dollar prices and continue to calculate a dollar price from the reported final money, par value and accrued interest.  Since the new dealer reported dollar price will not be used for clearance or settlement at DTCC, this data field will be able to be modified in RTRS by dealers to correct errors, even after trade matching had occurred.  In the event that the dollar prices disagree between dealers, RTRS will disseminate the RTRS-calculated dollar price and if the dealer reported dollar prices agree yet differ from the RTRS-calculated dollar price (which would occur if the security par value is no longer a $1,000 multiple) RTRS will disseminate the dealer reported dollar price.
