Securities description: securities backed by letters of credit. I am writing in connection with our previous telephone conversation of last June regarding the confirmation of a transaction in a municipal issue secured by an irrevocable letter of credit issued by a bank. In our conversation you noted that both rules G-12 and G-15 require confirmations to contain a:

description of the securities including at a minimum..., if necessary for a materially complete description of the securities, the name of any company or other person in addition to the issuer obligated, directly or indirectly, with respect to debt service...

You inquired whether the name of the bank issuing a letter of credit securing principal and interest payments on an issue, or securing payments under the exercise of a put option or tender option feature, need be stated on the confirmation.

At that time I indicated to you that the identity of the bank issuing the letter of credit would have to be disclosed on the confirmation if the letter of credit could be drawn upon to cover scheduled interest and principal payments when due, since the bank would be "obligated ... with respect to debt service." I am writing to advise that the committee of the Board which reviewed a memorandum of our conversation has concluded that a bank issuing a letter of credit which secures a put option or tender option feature on an issue is similarly "obligated ... with respect to debt service" on such issue. The identity of the bank issuing the letter of credit securing the put option must therefore also be indicated on the confirmation. MSRB interpretation of December 2, 1982.
