Confirmation Requirements for Partially Refunded Securities

Confirmation requirements for partially refunded securities. This will respond to your letter of May 16, 1989. The Board reviewed your letter at its August 1989 meeting and authorized this response.

You ask what is the correct method of computing price from yield on certain types of "partially prerefunded" issues having a mandatory sinking fund redemption. The escrow agreement for the issues provides for a stated portion of the issue to be redeemed at a premium price on an optional, "in-whole," call date for the issue. The remainder of the issue is subject to a sinking fund redemption at par.[1] Unlike some issues that are prerefunded by certificate number, the certificates that will be called at a premium price on the optional call date are not identified and published in advance. Instead, they are selected by lottery 30 to 60 days before the redemption date for the premium call. Prior to this time, it is not known which certificates will be called at a premium price on the optional call date. In the particular issues you have described, the operation of the sinking fund redemption will retire the entire issue prior to the stated maturity date for the issue.

As you know, rules G-12(c) and G-15(a) govern inter-dealer and customer confirmations, respectively. Rules G-12(c)(v)(1) and G-15(a)(i)(1)[*] require the dollar price computed from yield and shown on the confirmation to be computed to the lower of call date or maturity. For purposes of computing price to call, only "in-whole" calls, of the type which may be exercised in the event of a refunding, are used.[2] Accordingly, the Board previously has concluded that the sinking fund redemption in the type of issue you have described should be ignored and the dollar price should be calculated to the lowest of the "in-whole" call date for the issue (i.e., the redemption date of the prerefunding) or maturity. In addition, the stated maturity date must be used for the calculation of price to maturity rather than any "effective" maturity which results from the operation of the sinking fund redemption. Identical rules apply when calculating yield from dollar price. Of course, the parties to a transaction may agree to calculate price or yield to a specific date, e.g., a date which takes into account a sinking fund redemption. If this is done, it should be noted on the confirmation.[3]


In our telephone conversations, you also asked what is the appropriate securities description for securities that are advance refunded in this manner. Rules G-12(c)(v)(E) and G-15(a)(i)(E)[†] require that confirmations of securities that are "prerefunded" include a notation of this fact along with the date of "maturity" that has been fixed by the advance refunding and the redemption price. The rules also state that securities that are redeemable prior to maturity must be described as "callable".[4] In addition, rules G-12(c)(vi)(I) and G-15(a)(iii)(J)[‡] state that confirmations must include information not specifically required by the rules if the information is necessary to ensure that the parties agree to the details of the transaction. Since, in this case, only a portion of the issue will be chosen by lot and redeemed at a premium price under the prerefunding, this fact must be noted on the confirmation. As an example, the issue could be described as "partially prerefunded to [redemption date] at [premium price] to be chosen by lot-callable." The notation of this fact must be included within the securities description shown on the front of the confirmation. MSRB Interpretation of August 15, 1989.
