Changes to the continuing disclosure requirements for municipal bonds went into effect December 1, 2010. These changes, approved on May 26, 2010 with an effective date of December 1, are found in Rule 15c2-12 of the Securities and Exchange Commission (the "Rule"). The amendments do not affect continuing disclosure undertakings that were in effect prior to December 1, 2010, but will affect undertakings entered into on and after December 1, 2010.

Most municipal bonds issued since 1996 are subject to the Rule, which requires the issuer (or another "obligated person", such as a conduit borrower) to enter into a continuing disclosure undertaking at the time the bonds are issued. The issuer (or other obligated person) must agree to provide audits and regularly updated financial information to the marketplace, as well as to file a "Material Event Notice" if certain listed events occur.

The changes to the Rule cover two primary areas: (1) Material Event Notices, including the types of events that require the filing of a Material Event Notice and the timing of when a Material Event Notice must be filed; and (2) the application of the Rule to short-term variable rate demand obligations ("VRDOs").

Changes to Material Events; Timing of Material Event Notice Filings. Under the current Rule, a Material Event Notice must be filed in a timely manner if any of 11 listed events occur, if those events are material. The amended Rule requires that notices be filed within 10 business days of the occurrence of the applicable event. Material Event Notices (as well as regular annual continuing disclosure reports) must be filed with the Municipal Securities Rulemaking Board's Electronic Municipal Market Access system, or EMMA.

In addition, the amended Rule adds four new events to be reported, and modifies seven of the original 11 events. Most notably, seven of the original 11 events must now be reported without regard to whether they are material.

The following chart lists all 15 events and describes the Rule's requirements for each event, both before and after the Rule changes. In addition, the chart lists the existing Rule's additional requirement that issuers (or obligated persons) file a notice if required annual information disclosures are not filed in a timely manner.

Variable Rate Bonds. The amended Rule states that VRDOs are generally subject to the Rule. VRDOs, generally, are short-term obligations that bear interest at a variable rate that is reset periodically (usually weekly). VRDOs are commonly secured by a letter of credit from a bank; some VRDO structures require the bank to pay debt service on the bonds directly and others act as standby payors of debt service. Investors generally are able to sell the VRDOs back to the issuer, at specified times, for their full value. Prior to December 1, 2010, VRDOs with remarketing modes of nine months or less were not subject to the Rule. Beginning December 1, 2010, underwriters must require issuers of VRDOs with remarketing modes of nine months or less to enter into undertakings. This new requirement does not apply to VRDOs outstanding on November 30, 2010, even for remarketings which occur on or after December 1, 2010.

Note that the existing exemption in the Rule for bonds that mature in nine months or less has not been amended. Thus, short-term obligations, such as commercial paper, remain exempt from the continuing disclosure requirements of the Rule.
