Glass Lewis issued a controversy alert for Thai Beverage (SGX:Y92) shareholders ahead of the company's annual general meeting on Jan. 30, according to a recent release.

The alert relates to the frequent absences of executive chairman Charon Sirivadhanabakdi during company meetings.

In the previous financial year, Sirivadhanabakdi attended one out of five board meetings and two out of 13 executive committee meetings, while being absent from shareholder meetings.

The executive is up for reelection at the upcoming annual general meeting.

The alert's rationale relates to a precedent-setting and unique ESG issue and falls under board effectiveness and board responsiveness.
