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]

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.

The MSRB is publishing this notice to remind dealers of their affirmative disclosure obligations when effecting transactions with customers in original issue discount bonds. An original issue discount bond, or O.I.D. bond, is a bond that was sold at the time of issue at a price that included an original issue discount. The original issue discount is the amount by which the par value of the bond exceeded its public offering price at the time of its original issuance. The original issue discount is amortized over the life of the security and, on a municipal security, is generally treated as tax-exempt interest. When the investor sells the security before maturity, any profit realized on such sale is calculated (for tax purposes) on the adjusted book value, which is calculated for each year the security is outstanding by adding the accretion value to the original offering price. The amount of the accretion value (and the existence and total amount of original issue discount) is determined in accordance with the provisions of the Internal Revenue Code and the rules and regulations of the Internal Revenue Service.[1]

Rule G-17, the MSRB’s fair dealing rule, encompasses two general principles. First, the rule imposes a duty on dealers not to engage in deceptive, dishonest, or unfair practices. This first prong of Rule G-17 is essentially an antifraud prohibition. In addition to the basic antifraud provisions in the rule, the rule imposes a duty to deal fairly with all persons. As part of a dealer’s obligation to deal fairly, the MSRB has interpreted the rule to create affirmative disclosure obligations for dealers. The MSRB has stated that the dealer’s affirmative disclosure obligations require that a dealer disclose, at or before the sale of municipal securities to a customer, all material facts concerning the transaction, including a complete description of the security.[2] These obligations apply even when a dealer is effecting non-recommended secondary market transactions.

In the context of the sale to customers of an original issue discount security, the MSRB’s customer confirmation rule, Rule G-15(a), provides that information regarding the status of bonds as original issue discount securities must be included on customer confirmations. Specifically, Rule G-15(a)(i)(C)(4)(c) provides that, “If the securities pay periodic interest and are sold by the underwriter as original issue discount securities, a designation that they are “original issue discount” securities and a statement of the initial public offering price of the securities, expressed as a dollar price” must be included on the customer’s confirmation.

The MSRB previously has alerted dealers of their obligation to make original issue discount disclosures to customers and has stated that, “The Board believes that the fact that a security bears an original issue discount is material information (since it may affect the tax treatment of the security); therefore, this fact should be disclosed to a customer prior to or at the time of trade.”[3] The MSRB is publishing this notice to remind dealers of their disclosure obligations under Rule G-17 because it remains concerned that, absent adequate disclosure of a security’s original issue discount status, an investor might not be aware that all or a portion of the component of his or her investment return represented by accretion of the discount is tax-exempt, and therefore might sell the securities at an inappropriately low price (i.e., at a price not reflecting the tax-exempt portion of the discount) or pay capital gains tax on the accreted discount amount. Without appropriate disclosure, an investor also might not be aware of how his or her transaction price compares to the initial public offering price of the security. Appropriate disclosure of a security’s original issue discount feature should assist customers in computing the market discount or premium on their transaction.

[3] Rules G-12 and G-15, Comments Requested on Draft Amendments on Original Issue Discount Securities, MSRB Reports, Vol. 4, No. 6 (May 1994) at 7.

The Board has received questions concerning the appropriate allocation of supervisory responsibility between municipal securities principals and the new category of municipal securities sales principals. The Board recently amended its rule G-3 to permit a person associated with a securities firm whose activities with respect to municipal securities are limited to supervising sales to and purchases from customers to qualify as a "municipal securities sales principal" ("sales principal"). The Board also amended rules G-8 on recordkeeping, G-26 on the administration of customer accounts, and G-27 on supervision to permit securities firms to designate sales principals as responsible for certain supervisory functions insofar as they relate directly to transactions in municipal securities with customers.

In particular, rule G-27 concerning supervision requires municipal securities dealers to designate at least one municipal securities principal as responsible for supervising its municipal securities activities, including the municipal securities activities of branch offices or similar locations. In addition, rule G-27 permits the municipal securities dealer to designate a sales principal (e.g., a branch office manager) as responsible for the "direct supervision of sales to and purchases from customers." The rule also requires that a dealer adopt written supervisory procedures which, among other matters, reflect the delegation of supervisory authority to these personnel.

As a result of these amendments, in designating under rule G-27 one or more municipal securities principals as responsible for supervising the business and activities of the firm’s associated persons, a securities firm may choose to designate a qualified sales principal with limited responsibility for the direct supervision of sales to and purchases from customers. If so, the firm’s written supervisory procedures may allocate responsibility to a sales principal for reviewing and approving (to the extent that they relate to sales to and purchases from customers) the suitability of the opening of, and transactions in, customer accounts, the handling of customer complaints and other correspondence, and other matters permitted by Board rule to be reviewed or approved by a sales principal. A municipal securities principal, however, must be responsible for directly supervising the firm’s other municipal securities activities such as underwriting, trading, and pricing of inventories.

With respect to the relationship between a sales principal and the designated municipal securities principal, Board rule G-27 provides that a branch office manager who acts as the sales principal for his office will be responsible for the municipal securities sales activities under his direct supervision. Rule G-27 also provides that a designated municipal securities principal will be responsible for all municipal securities activities of the branch office including those that may be under the direct supervision of a sales principal. However, the branch office manager, under the particular organizational structure of a firm, may be responsible to some other designated supervisor for the discharge of his other duties.

Syndicate records: participations. This will acknowledge receipt of your letter of November 24, 1981 concerning certain of the requirements of Board rule G-8(a)(viii) regarding syndicate records to be maintained by managers of underwritings of new issues of municipal securities.

You note that this provision requires, in pertinent part, that,

[w]ith respect to each syndicate..., records shall be maintained ... showing ... the name and percentage of participation of each member of the syndicate or account...

You inquire whether this provision necessitates the designation of an actual percentage or decimal participation, or, alternatively,

whether a listing of the ... dollar participation [of each member] ... along with [the] aggregate par value of the syndicate meets the requirement ... of the Rule.

The rule should not be construed to require in all cases an indication of a numerical percentage for each member's participation, if other information from which a numerical percentage can easily be determined is set forth. The method you propose, showing the par value amount of the member's participation, is certainly acceptable for purposes of compliance with this provision of the rule. MSRB interpretation of December 8, 1981.

Records of original entry: unit system. This will acknowledge receipt of your letter of November 20, 1981 concerning compliance with certain of the provisions of Board rule G-8 through the use of a "unit system" method of recordkeeping. In your letter you indicate that the bank wishes to maintain the record of original entry required under rule G-8(a)(i) in the form of a collection of duplicate copies of confirmations filed in transaction settlement date order; in addition, you enclose a copy of the confirmation form used by the bank. You inquire whether maintaining the record in this manner would be satisfactory for purposes of the rule.

In a July 29, 1977 interpretive notice on rule G-8 the Board stated:

Under rule G-8, records may be maintained in a variety of ways, including a unit system of recordkeeping. In such a system, records are kept in the form of a group of documents or related groups of documents....

A unit system of recordkeeping is an acceptable system for purposes of rule G-8 if the information required to be shown is clearly and accurately reflected and there is an adequate basis for audit. This would require in most instances that each record in a unit system be arranged in appropriate sequence, whether chronological or numerical, and fully integrated into the over-all recordkeeping system for purposes of posting to general ledger accounts.

Therefore, the type of recordkeeping system you propose may be used for purposes of compliance with rule G-8 if (1) the records show, in a clear and accurate fashion, all of the information that is required to be shown, and (2) the records are maintained in a form that provides an adequate basis for audit by bank employees or examiners. It is my understanding that recordkeeping systems similar to that which you propose have been inspected by banking regulatory authorities during examinations of other bank municipal securities dealer departments, and have been found to meet these two criteria.

In your letter you indicate that the confirmation form used by your bank "contains all the information needed" to meet the recordkeeping requirement. Our review of your form indicates that this is not the case. The rule requires the record of original entry to contain

an itemized daily record of all purchases and sales of municipal securities, all receipts and deliveries of municipal securities (including bond or note numbers and, if the securities are in registered form, an indication to such effect), all receipts and disbursements of cash with respect to transactions in municipal securities, [and] all other debits and credits pertaining to transactions in municipal securities ... The records of original entry shall show the name or other designation of the account for which each such transaction was effected (whether effected for the account of such municipal securities broker or municipal securities dealer, the account of a customer, or otherwise), the description of the securities, the aggregate par value of the securities, the dollar price or yield and aggregate purchase or sale price of the securities, accrued interest, the trade date, and the name or other designation of the person from whom purchased or received or to whom sold or delivered.

The confirmation form you enclosed does not appear to provide a space for notation of "the name or other designation of the account for which [the] transaction was effected." This information is distinct from "the name or other designation of the person from whom purchased ... or to whom sold ..." (which would appear in the "name and address" portion of your form) and requires an indication of the account, whether it be the bank's trading inventory or portfolio, or the contra-principal on an agency transaction, in which the securities were held prior to a sale or will be held subsequent to a purchase. For example, if the bank sells $100,000 par value securities from its trading account to "Mr. Smith", the record of original entry would reflect that this transaction was effected for the account of the [bank's] trading account. A subsequent sale of these securities effected as agent for the customer would be reflected on the record of original entry as for the account of "Mr. Smith."

I note also that, in addition to a record of purchase and sale transactions (which could easily be maintained in the form of duplicate copies of confirmations), the record of original entry must contain information about transactions cleared on the date of the record as well as cash disbursements and receipts. Your letter does not indicate how your bank would comply with these latter requirements. As you may be aware, other banks using unit recordkeeping systems use additional copies of the confirmation as "clearance" records, with information on receipts and deliveries of securities and movements of cash noted on these copies. These "clearance" records are then aggregated with the purchase and sale records to form a complete record of original entry.

In summary, the method of maintaining a record of original entry which your bank proposes can be used to comply with the requirements of the rule. Certain aspects of the information required by the rule are not contained on the document you propose to use, however, and provision would have to be made for inclusion of these items in the records before the system you propose would be satisfactory for compliance with the rule's requirements. MSRB interpretation of November 24, 1981.

Syndicate records. I am writing in response to your letters of October 2 and October 19, 1981 concerning a particular recordkeeping arrangement used by an NASD-member firm in connection with its underwriting activities. In your letters you indicate that the firm conducts its underwriting activities from its main office and four regional branch office "commitment centers," with the committing branch offices authorized to commit to underwriting new issues on the firm's behalf. You inquire whether the firm is in compliance with the Board's recordkeeping and record retention rules if it maintains only part of the records on its underwritings in the main office. Correspondence from a field examiner attached to your letters indicates that the committing branch office originating a particular underwriting maintains all of the records with respect to such underwriting. The majority of these records are the original copies; the copies of confirmations, good faith checks, and syndicate settlement checks maintained at the committing branch office are duplicates of original records maintained at the firm's main office.

Rule G-9(d) requires that books and records shall be maintained and preserved in an easily accessible place for two years and shall be available for ready inspection by the proper regulatory authorities. The fact that the member firm does not maintain all records with respect to all of its underwriting activities in a single location does not contravene these provisions of Board rule G-9. Rule G-9 would permit the arrangement described in your letters, whereby a firm maintains copies of all of the records pertaining to a particular underwriting in the office responsible for that underwriting.

Thank you for your prompt assistance in providing the additional information we needed in order to respond to your inquiry. MSRB interpretation of October 21, 1981.

Settlement of syndicate accounts. This is in response to your letter of July 28, 1981, suggesting that requirements analogous to those placed on syndicate managers in rule G-12(j) be imposed on syndicate members who must remit their share of syndicate losses to their syndicate managers. You state that syndicate members frequently do not remit their losses to the manager in a timely fashion and that such a requirement would establish an "equitable balance between the interests of syndicate members and syndicate managers."

Rule G-12(j) provides:

Final settlement of a syndicate or similar account formed for the purchase of securities shall be made within 60 days following the date all securities have been delivered by the syndicate or account manager to the syndicate or account members.

The rule is not expressly limited to money payments by syndicate managers, but broadly requires that final settlement shall be made within 60 days following the date the manager delivers the securities to the syndicate members. Thus, the rule requires syndicate members to remit their share of syndicate losses to the syndicate manager within the 60-day period set forth in the rule. Since a syndicate member cannot remit his share of losses until he is apprised by the syndicate manager of the amount of his share, a member should remit his share of the losses to the manager within a reasonable period of time after receiving the syndicate accounting required by rule G-11(h). MSRB interpretation of September 28, 1981.

Certain amendments to Board rule G-15 on customer confirmations became effective on December 1, 1980. Among other matters, these amendments require that customer confirmations of transactions effected on the basis of dollar price, including confirmations of purchases from customers, set forth certain yield information concerning the transaction. Confirmations of dollar price transactions in non-callable securities, or in callable securities traded at prices below par, must set forth the yield to maturity resulting from the dollar price. Confirmations of dollar price transactions in securities which have been called or prerefunded must show the yield to the maturity date established by the call or prerefunding. Confirmations of transactions in callable securities traded at dollar prices in excess of par are exempt from yield disclosure requirements until October 1, 1981; after that date such confirmations must show the lowest of the yield to premium call, yield to par option, or yield to maturity resulting from such dollar price.[1]

Since the effective date of these amendments, the Board has received several inquiries as to whether all confirmations of purchases from customers, including purchases effected at a price derived from a yield price less a spread or concession, must show the yield resulting from the actual unit dollar price of the transaction.

The Board is of the view that all confirmations of purchasers from customers (except for purchases at par) must set forth the net or effective yield resulting from the actual unit dollar price of the transaction. The yield disclosure on confirmations of purchases from customers is intended to provide customers with a means of assessing the merits of alternative investment strategies (such as different possible reinvestment transactions) and the merits of the particular transaction being confirmed. The Board believes that the disclosure of the net or effective yield (i.e., that derived from the actual unit dollar price of the transaction) best serves these purposes.

[1] Confirmations of transactions effected at a dollar price of par ("100") continue to be exempt from any yield disclosure requirements.

The Municipal Securities Rulemaking Board has recently received inquiries concerning the provisions of rule G-12(h)(iii) regarding close-out procedures in the event of a firm's liquidation. The Board has been advised that a SIPC trustee has been appointed in connection with the liquidation of a general securities firm with which certain municipal securities brokers and dealers have uncompleted transactions in municipal securities, and that the New York Stock Exchange and the National Association of Securities Dealers, Inc., have notified their respective members that they may institute "immediate" close-out procedures on open transactions with the firm in liquidation. In accordance with a previous understanding between the Board and the NASD, the NASD has also advised municipal securities brokers and dealers that, pursuant to rule G-12(h)(iii), they may execute "immediate" close-outs on open transactions in municipal securities.

Rule G-12(h)(iii) provides:

Nothing herein contained shall be construed to prevent brokers, dealers or municipal securities dealers from closing out transactions as directed by a ruling of a national securities exchange, a registered securities by a ruling of a national securities exchange, a registered securities association or an appropriate regulatory agency issued in connection with the liquidation of a broker, dealer or municipal securities dealer.

Therefore, in the event that a national securities exchange or registered securities association makes a ruling that close-outs may be effected "immediately" on transactions with a firm in liquidation, municipal securities brokers and dealers may take such action. In these circumstances, a purchasing dealer seeking to execute such a close-out need not follow the procedures for initiation of a close-out procedure, nor is the dealer required to wait the prescribed time periods prior to executing the close-out notice. Similarly, a selling dealer need not attempt delivery prior to using the procedure for close-outs by sellers. In both cases dealers may proceed to execute the close-out immediately--that is, the purchasing dealer may immediately "buy in" the securities in question for the account and liability of the firm in liquidation (or utilize one of the other options available for execution of the close-out), and a selling dealer may immediately "sell out" the subject securities. Notification of the execution of the close-out should be provided in accordance with the normal procedure.

Dealers executing close-outs in these circumstances should advise the trustee of the firm in liquidation of their actions in closing out these transactions. If proceeds from the close-out execution are due to the firm in liquidation, they should be remitted to the trustee. Requests for payment of amounts due on close-out executions should also be sent to the trustee; the trustee will resolve these claims in the course of the liquidation.

The Board also notes that dealers having open transactions with a firm in liquidation may, but are not required to, execute "immediate" close-outs in these circumstances. If individual dealers wish to attempt some other means of completing these transactions, such as seeking to complete a transaction with the liquidated firm's other contra-side, they may do so.

Blanket consent. This is in response to your April 7, 1981, letter asking whether, consistent with rule G-23(d)(ii), a municipal securities dealer acting as a financial advisor to an issuer may obtain from the issuer prospective approval to participate in any and all new issues the issuer may sell on a competitive basis at some future date.

Rule G-23(d)(ii) provides that a municipal securities dealer which is acting as a financial advisor may not acquire or participate in the distribution of a new issue unless

if such issue is to be sold by the issuer at competitive bid the issuer has consented in writing to such acquisition or participation.

The rule is designed to minimize the "prima facie" conflict of interest that exists when a municipal securities professional acts as both financial advisor and underwriter with respect to the same issue. Rule G-23(d) speaks in terms of "a new issue" and the implication is that consent should be obtained on an issue-by-issue basis.

The Board believes that such a reading of the rule is consistent with the rule’s rationale—that an issuer should have an opportunity to consider whether, under the particular circumstances of an offering, the financial advisor’s potential conflict of interest is sufficient to warrant not consenting to its participation in the sale. The Board has concluded that an unrestricted consent would not afford an issuer such an opportunity and, accordingly, has determined that such a consent would not satisfy the requirements of rule G-23(d)(ii). MSRB interpretation of July 30, 1981.

Disclosure of pricing: accrued interest. This is in response to your request by telephone for an interpretation of Board rule G-15 which requires that a municipal securities dealer provide to his customer, at or prior to completion of a transaction, a written confirmation containing certain general information including the amount of accrued interest. Specifically, you have asked whether the rule permits a municipal securities dealer, in using one confirmation to confirm transactions in several different municipal securities of one issuer, to disclose the amount of accrued interest for the bonds as an aggregate figure. You have advised us that, typically, such a confirmation will show other items of information required by the rule such as yield and dollar price, separately for each issue.

Rule G-15 was adopted by the Board to assure that confirmations of municipal securities transactions provide investors with certain fundamental information concerning transactions. The Board believes that disclosure of accrued interest as an aggregate sum does not permit investors to determine easily from the confirmation the amount of accrued interest attributable to each security purchased, but rather necessitates the performance of several computations. It, thus, would be more difficult for an investor to determine whether the information concerning accrued interest is correct if the information is presented in aggregate form.

Such a result is inconsistent with the purposes of rule G-15. Accordingly, the Board has concluded that, under rule G-15, the amount of accrued interest must be shown for each issue of bonds to which the customer confirmation relates. MSRB interpretation of July 27, 1981.

Letters of credit. This is in response to your April 9, 1981, letter asking whether Board rule G-22, regarding control relationships, and G-23, regarding financial advisory agreements, would apply if a bank’s issuance of a letter of credit were contingent upon its being named underwriter or manager for the issue, or if a bank issuing a letter of credit retained authority to require an issuer, in effect, to call the securities.

Rule G-22 provides that

a control relationship with respect to a municipal security shall be deemed to exist if a broker, dealer, or municipal securities dealer (or a bank or other person of which the broker, dealer, or municipal securities dealer is a department or division) controls, is controlled by, or is under common control with the issuer of the security or a person other than the issuer who is obligated, directly or indirectly, with respect to debt service on the security.

The existence of a control relationship is a question of fact to be determined from the entire situation. Most recently, the Securities and Exchange Commission suggested that, for purposes of the Regulatory Flexibility Act, a registered broker-dealer would be deemed to be controlled by a person or entity who, among other things, has the ability to direct or cause the direction of management or the policies of the broker-dealer. Based upon the above, it is questionable whether a bank that conditions the issuance of a letter of credit upon being named an underwriter or upon a tie-in deposit arrangement should be deemed to control the issuer. Similarly, it does not appear that a bank that retains discretion under a letter of credit to cause the trustee to call the whole issue has a control relationship with the issuer.

You also ask whether under Board rule G-23 a financial advisory relationship is created if a bank conditions the issuance of a letter of credit upon being named an underwriter or upon obtaining a tie-in deposit arrangement. Under rule G-23, a financial advisory relationship is deemed to exist when a municipal securities professional provides, or enters into an agreement to provide, financial advisory services to, or on behalf of, an issuer with respect to a new issue of securities regarding such matters as the structure, timing or terms of the issue, in return for compensation or for the expectation of compensation. It does not appear that rule G-23 would apply in your example since the bank is not providing financial advisory or consulting services with respect to the structure, timing or other substantive terms of the issue. MSRB interpretation of July 27, 1981.
