that county.
(2) An elections official conducting an audit pursuant to this section shall do all of the following:
(A) Provide at least a five-day public notice of the time and place of the random selection of the audit units to be manually tallied and of the time and place of the audit.
(B) Make available to the public a report of the vote tabulating device results for the contest, including the results for each audit unit in the contest, prior to the random selection of audit units to be manually tallied and prior to the commencement of the audit.
(C) Conduct the audit upon tabulation of the unofficial final results or upon completion of the official canvass for the election.
(D) Conduct
the audit in public view by hand without the use of electronic scanning equipment using the tally procedures established by Section 15360 for conducting a manual tally.
(3) On or before March 1, 2012, the Secretary of State shall report to the Legislature on the effectiveness and efficiency of postcanvass risk-limiting audits conducted pursuant to this section. The report shall include an analysis of the efficiency of postcanvass risk-limiting audits, including the costs of performing the audits, as compared to the 1-percent manual tallies conducted in the same election pursuant to Section 15360.
(c) An audit shall not be conducted pursuant to this section with respect to a state or multijurisdictional contest unless all of the counties involved in the contest choose to participate in the pilot program authorized by this section.
(d) For purposes of this section, the following terms have the following meanings:
(1) “Audit unit” means a precinct, a set of ballots, or a single ballot. A precinct, a set of ballots, or a single ballot may be used as an audit unit for purposes of this section only if all of the following conditions are satisfied:
(A) The relevant vote tabulating device is able to produce a report of the votes cast in the precinct, set of ballots, or single ballot.
(B) The elections official is able to match the report described in subparagraph (A) with the ballots corresponding to the report for purposes of conducting an audit pursuant to this section.

A risk-limiting audit shall begin with a hand tally of the votes in one or more audit units and shall continue to hand tally votes in additional audit units until
there is strong statistical evidence that the electoral outcome is correct. In the event that counting additional audit units does not provide strong statistical evidence that the electoral outcome is correct, the audit shall continue until there has been a full manual tally to determine the correct electoral outcome of the audited contest.
(4) “Unofficial final results” means election results tabulated pursuant to an official canvass conducted pursuant to Chapter 4 (commencing with Section 15300) but not yet reported to the governing board or the Secretary of State pursuant to subdivision (h) of Section 15302.
