Current Refundings. This is in response to your letter of July 10, 1991. You note that, pursuant to recently adopted amendments to rule G-36, underwriters are required to deliver advance refunding documents (i.e., escrow agreements) to the Board. You state that, under Section 149(d)(5) of the Internal Revenue Code of 1986, as amended, an advance refunding issue is one which will be issued more than 90 days before the redemption of the refunded bonds. Escrow deposits customarily are made of U.S. government obligations or other highly-rated securities which are sufficient to pay principal and interest to retire the bonds being refunded over some period of time. You note, however, that for current refundings, there also are short-term escrows established for periods of less than 90 days which involve the investment of bond proceeds in permitted defeasance securities until the first permitted redemption date. You ask whether it is necessary to file Form G-36(ARD) and the related documents when the escrow period is less than 90 days. The Board has reviewed your request and has authorized this response.

Rule G-36 requires underwriters, among other things, to provide advance refunding documents to the Board. The purpose of this requirement is so these documents will be available through the Board's Municipal Securities Information Library^(TM) (MSIL^(TM)) system, to the holders of the refunded issues, as well as dealers and customers effecting transactions in such issue. In general, municipal securities industry participants consider advance refunding issues as those issued more than 90 days before the redemption of the refunded bonds. The current refunding issues you describe would not be considered advance refunding issues. Thus, rule G-36 does not require underwriters to provide the Board with escrow agreements for current refundings.

*In 2009, the MSRB amended and consolidated Rule G-36, on delivery of official statements, advance refunding documents and forms G-36(OS) and G36(ARD) and Rule G-32, on disclosures in connection with new issues into Rule G-32, on disclosures in connection with primary offerings. See Release No. 34-59966 (May 21, 2009), 102 FR 25790 (May 29, 2009). Effective May 10, 2021, this notice expressly shall apply to analogous interpretive issues under Rule G-32, on disclosures in connection with primary offerings.
