Contents of advertisement: put options. Your letter dated June 15, 1981, has been referred to me for response. In your letter you mention our previous conversation regarding the appropriate definition of "put bonds", which definition your firm would like to use in advertisements offering such securities for sale. You request confirmation of the Board’s views concerning the aspects of the "put option" feature on these securities that would be appropriate to cover in such a definition.

The type of "put option" issue with which the Board is familiar, and which we discussed, has a provision in the indenture which permits the holder of the securities to tender or "put" the securities back to the issuer on specified dates at par. This feature typically commences six (or more) years after the date of issuance, is exercisable only once annually (on an interest payment date), and is exercisable only upon the provision of irrevocable prior notice to the issuer (typically three or more months before the exercise date).

If I remember our conversation correctly, you indicated that the firm wished to describe a security of this type in an advertisement as having a "put option" feature, available once annually, permitting redemption of the securities at par. I suggested that, while the items of information you detailed were appropriate, it might also be advisable to mention in the advertisement the "prior notice" requirement under the option exercise procedure. It would also be helpful to make clear the irrevocable nature of such notice.

If the content of your definition of the "put option" feature goes beyond the items we discussed (for example, by indicating that the "put option" is secured by a bank letter of credit, additional disclosures might also be appropriate. MSRB interpretation of July 13, 1981.
