Extends the effectiveness of certain provisions relating to refunding bonds

This bill extends the expiration date of specific rules regarding refunding bonds from September 30, 2026, to September 30, 2029. It directly affects local governments and financial entities that issue refunding bonds, allowing them to continue using these provisions for an additional three years. The mechanism simply amends an existing law to update the end date of its effectiveness without changing the underlying requirements for the bonds. This change ensures that the current framework for these financial instruments remains in place until the new deadline.
