Callable Securities: Pricing to Mandatory Sinking Fund Calls

Callable securities: pricing to mandatory sinking fund calls. This is in response to your February 21, 1986 letter concerning the application of rule G-15(a) regarding pricing to prerefunded bonds with mandatory sinking fund calls.

You give the following example:

Bonds, due 7/1/10, are prerefunded to 7/1/91 at 102. There are $17,605,000 of these bonds outstanding. However, there is a mandatory sinking fund which will operate to call $1,000,000 of these bonds at par every year from 7/1/86 to 7/1/91. The balance ($11,605,000) then will be redeemed 7/1/91 at 102. If this bond is priced to the 1991 prerefunded date in today's market at a 6.75 yield, the dollar price would be approximately 127.94. However, if this bond is called 7/1/86 at 100 and a customer paid the above price, his/her yield would be a minus 52 percent (-52%) on the called portion.

You state that the correct way to price the bond is to the 7/1/86 par call at a 5% level which equates to an approximate dollar price of 102.61. The subsequent yield to the 7/1/91 at 102 prerefunded date would be 12.33% if the bond survived all the mandatory calls to that date. You note that a June 8, 1978, MSRB interpretation states, "the calculation of dollar price to a premium call or par option date should be to that date at which the issuer may exercise an option to call the whole of a particular issue or, in the case of serial bonds, a particular maturity, and not to the date of a call in-part." You believe, however, that, as the rule is presently written, dealers are leaving themselves open for litigation from customers if bonds, which are trading at a premium, are not priced to the mandatory sinking fund call. You ask that the Board review this interpretation.

Your letter was referred to a Committee of the Board which has responsibility for interpreting the Board's fair practice rules. That Committee has authorized this response.

Rule G-15(a)(i)(I)[*] requires that on customer confirmations the yield and dollar price for the transaction be disclosed as the price (if the transaction is done on a yield basis) or yield (if the transaction is done on the basis of the dollar price) calculated to the lowest price or yield to call, to par option, or to maturity. The provision also requires, in cases in which the resulting dollar price or yield shown on the confirmation is calculated to call or par option, that this must be stated and the call or option date and price used in the calculation must be shown. The Board has determined that, for purposes of making this computation, only "in-whole" calls should be used.[1] This requirement reflects the longstanding practice of the municipal securities industry that a price calculated to an "in-part" call, such as a sinking fund call, is not adequate because, depending on the probability of the call provision being exercised and the portion of the issue subject to the call provision, the effective yield based on the price to a sinking fund date may not bear any relation to the likely return on the investment.

Rule G-15(a)(i)(I)[*] applies, however, only when the parties have not specified that the bonds are priced to a specific call date. In some circumstances, the parties to a particular transaction may agree that the transaction is effected on the basis of a yield to a particular date, e.g. put option date, and that the dollar price will be computed in this fashion. If that is the case, the yield to this agreed upon date must be included on confirmations as the yield at which the transaction was effected and the resulting dollar price computed to that date, together with a statement that it is a "yield to [date]." In an August 1979 interpretive notice on pricing of callable securities, the Board stated that, under rule G-30, a dealer pricing securities on the basis of a yield to a specified call feature should take into account the possibility that the call feature may not be exercised.[2] Accordingly, the price to be paid by the customer should reflect this possibility, and the resulting yield to maturity should bear a reasonable relationship to yields on securities of similar quality and maturity. Failure to price securities in such a manner may constitute a violation of rule G-30 since the price may not be "fair and reasonable" in the event the call feature is not exercised. The Board also noted that the fact that a customer in these circumstances may realize a yield in excess of the yield at which the transaction was effected does not relieve a municipal securities dealer of its responsibilities under rule G-30.

Accordingly, the calculation of the dollar price of a transaction in the securities in your example, unless the parties have agreed otherwise, should be made to the prerefunded date. Of course, under rule G-17 on fair dealing, dealers must explain to customers the existence of sinking fund calls at the time of trade. The sinking fund call, in addition, should be disclosed on the confirmation by an indication that the securities are "callable." The fact that the securities are prerefunded also should be noted on the confirmation. MSRB Interpretation of April 30, 1986.
