(a) If a specific-purpose committee for supporting or opposing a candidate or measure expects no reportable activity in connection with the election to occur after the period covered by a report filed under this subchapter, the committee’s campaign treasurer may designate the report as a “final” report.
(b) The designation of a report as a final report:
(1) relieves the campaign treasurer of the duty to file additional reports under this subchapter, except as provided by Subsection (c); and
(2) terminates the committee’s campaign treasurer appointment.

(c) If, after a committee’s final report is filed, reportable activity with respect to the election occurs, the committee must file the appropriate reports under this subchapter and is otherwise subject to the provisions of this title applicable to political committees. A report filed under this subsection may be designated as a final report.
