1. Number and term of office of audit committee members.
2. Powers of the audit committee.
3. Rules of procedure for meetings of the audit committee.
4. Resources to be provided by the company when the audit committee exercises its powers.
The charter under the preceding paragraph, and any amendment thereto, shall be adopted by resolution of the board of directors.

The audit committee shall be composed of the entire number of independent directors. It shall not be fewer than three persons in number, one of whom shall be committee convenor, and at least one of whom shall have accounting or financial expertise.

Persons to represent the company in matters under Articles 213, 214, and 223 of the Company Act shall be selected by the audit committee by the procedure set out in the preceding paragraph. The audit committee may resolve for members to individually represent or jointly represent the company in such matters. If representatives are not selected by the procedure in the preceding paragraph, the entire membership shall jointly represent the company.
The term "entire membership" as used in these Regulations shall be calculated as the number of members actually in office.

The matters set out in the subparagraphs of Article 14-5, paragraph 1, of the Act shall be subject to the consent of one-half or more of the entire membership of the audit committee and be submitted to the board of directors for a resolution.

An audit committee shall meet at least quarterly, which shall be set out in the audit committee charter.
The reasons for calling a meeting of the audit committee shall be notified to each independent director member at least seven days in advance. In emergency circumstances, however, this requirement does not apply.

One member shall be elected as the convener and meeting chair by and from among the entire membership of the audit committee. However, if the audit committee members are unable to elect a convener, the independent director who received votes representing the largest share of the voting rights shall serve as the convener.
When the convener goes on leave or otherwise for any reason whatsoever is unable to convene a meeting, the meeting shall be convened by another independent director member designated by the convener, or if no such designation is made, by another member elected by and from among the independent director members of the committee.
Independent directors constituting one-half or more of the entire membership of the audit committee may, by filing a written proposal setting forth the subjects for discussions and the reasons, request the convener to convene a meeting of the audit committee.

The audit committee may by resolution request relevant department officers, internal auditors, certified public accountants, legal counsels, or other personnel to attend the meeting as nonvoting participants and provide pertinent and necessary information; provided, they shall leave the meeting when discussion and voting take place.

When an audit committee meeting is held, the company shall have an attendance book ready for signature by the independent director members attending the meeting and thereafter keep it available for future reference.
All independent director members on the audit committee shall attend committee meetings in person; a member who cannot attend in person may appoint another independent director member to attend as their proxy. Attendance via tele- or video-conference is deemed attendance in person.

A proxy under paragraph 2 may accept a proxy from one person only.

When the time of a meeting has arrived, if the audit committee members present do not reach one-half of the entire membership, the meeting chair may announce that the meeting time will be postponed to later on the same day, provided that only two postponements may be made. If the quorum is still not met after two postponements, the chair may re-call the meeting following the procedures provided in Article 7, paragraph 2.

The meeting chair may not declare the meeting closed without the approval of one-half or more of the entire membership of the audit committee.

If at any time during the proceedings of an audit committee meeting, the convener for any reason is unable to chair the meeting or the chair fails to declare the meeting closed as provided in paragraph 2, the provisions of Article 7, paragraph 5 shall apply mutatis mutandis to the selection of the deputy to act in place thereof.

If an independent director member of the audit committee has a personal interest in any agenda item, the director shall explain the essential content of the interest. If the director's personal interest is likely to prejudice the interest of the company, the director member may not participate in discussion and voting, and shall recuse himself or herself from the discussion and voting, and also may not exercise voting rights as a proxy for any other independent director member.
Where the spouse or a blood relative within the second degree of kinship of an independent director is an interested party with respect to an agenda item as described in the preceding paragraph, such director shall be deemed to be an interested party with respect to that agenda item.
