American Chamber of Commerice Cambodia

Amcham Cambodia

Board of Governors

About the Board of Governors (BoG)

There are nine AmCham Governors sitting on the board at all times. AmCham Governors are elected by the membership at the annual general meeting. All member companies and organizations my propose a candidate to the selection committee prior to the election. The selection committee will select two possible candidates for each available position. A majority vote by the membership elects the new Governors.

Governors sit for a two year term and may stand for re-election at the end of their term. Governor terms are staggered; meaning one year 4 seats are up for election, and the following year, the other five seats become available. Following each annual election, the board elects officers; Chair, Vice Chair, Secretary and Treasurer from among the sitting board members. Terms for these board officer positions are one year.

In order to recognize special long term service to the AmCham community, the board has established "emeritus" board positions, which are granted for life. Two of these have been granted to date; a Chairman Emeritus position to Mr. Bretton G. Sciaroni and a Member Emeritus position to Mr. Michael Hayes. This honor forever places these individuals in the AmCham spirit and bestows on them the privileged of attending BoG meetings as non-voting consultants.
