Yield Disclosures: Yields to Call on Zero Coupon Bonds
Yield disclosures: yields to call on zero coupon bonds. I am writing in response to your letter of October 18, 1983 concerning the appropriate method of disclosing on a confirmation a call price used in the computation of a dollar price or yield on a transaction in a zero coupon, compound interest, multiplier, or other similar type of security. In your letter you indicate that the call features on these types of securities often express the call prices in terms of a percentage of the compound accreted value of the security as of the call date. You note that, in computing a price or yield to such a call feature, it is necessary for the computing dealer to convert such a call price into its equivalent in terms of a percentage of maturity value (i.e., into a standard dollar price), and use this figure in the computation. You inquire whether, in circumstances where the confirmation of a transaction is required to disclose a yield or dollar price computed to such a call feature, the call price used in the calculation should be stated on the confirmation in terms of the percentage of the compound accreted value or in terms of the equivalent percentage of maturity value.
The requirement which is the subject of your inquiry is set forth in Board rule G-15(a)(i)(I)[*] as follows:
In cases in which the resulting dollar price or yield shown on the confirmation is calculated to call or par option, this must be stated, and the call or option date and price used in the calculation must be shown...
The Board is of the view that, in the case of a computation of a yield or dollar price to a call or option feature on a transaction in a zero coupon or similar security, the call price shown on the confirmation should be expressed in terms of a percentage of the security's maturity value. The Board believes that the disclosure of the call price in terms of the security's maturity value would provide more meaningful information to the purchaser, since other confirmation disclosure on these types of securities are also expressed in terms of the security's maturity value. This form of disclosure therefore presents the information to a purchaser in a consistent format, thereby facilitating the purchaser's understanding of the information shown on the confirmation. The Board notes also that this form of disclosure is simpler and requires less confirmation space to present. MSRB interpretation of January 4, 1984.
 For example, the selected portions of an official statement describing one of these types of issues enclosed with your letter indicate that the security in question is callable on October 1, 1993 at 108% of the security's compound accreted value on that date (which is indicated elsewhere in the official statement to be $146.02 per $1,000 of maturity value).
 Comparable requirements with respect to inter-dealer confirmations are set forth in Board rule G-12(c)(v)(I).
