Callable securities: extraordinary mandatory redemption features. I am writing in response to your letter of February 15, 1983 regarding the confirmation disclosure requirements applicable to municipal securities which are subject to extraordinary mandatory redemption features. In your letter you inquire whether such securities need be identified as "callable" securities on the confirmation. You also inquire as to the relationship between an extraordinary mandatory redemption feature and a "catastrophe call" feature, and the disclosure requirements applicable to the latter type of provision.

An extraordinary mandatory redemption feature, in my understanding, is a call provision under which an issuer of securities would be obliged to call all or a part of an issue if certain stated unexpected events occur. For example, many of the recent mortgage revenue issues have extraordinary mandatory redemption provisions under which securities would be called if a portion of the proceeds of the issue has not been used to acquire mortgages by a certain stated date, or if moneys received from principal prepayments have not been used to acquire new mortgages by a certain period following receipt of the prepayment. In general, securities which are subject to extraordinary mandatory redemption provisions must be identified as "callable" securities on any confirmation. Extraordinary redemption provisions would not, however, be used for purposes of computing a yield or dollar price.

One specific type of extraordinary mandatory redemption provision is what has been colloquially termed a "catastrophe" or "calamity" call provision. Under this type of provision the issuer of securities would be obliged to call all or part of an issue if the financed project is destroyed or damaged by some catastrophe (e.g., by fire, flood, lightning or other act of God) or if the tax exempt status of the issue is negated. The Board has previously expressed the view that securities which are callable solely under this type of "catastrophe" call provision, and are not otherwise callable, need not be designated as "callable" securities on a confirmation.

In summary, therefore, securities which are subject to extraordinary mandatory redemption provisions other than "catastrophe" call provisions must be identified as "callable" securities on confirmations. MSRB interpretation of February 18, 1983.
