        <ExplanationTxt>New Board members, who are generally elected in June, attend an orientation in the summer at which the Board's by-laws are reviewed, including its conflict of interest policy (Article XI). Examples of conflicts are discussed at orientation to familiarize Board members with the concept and new Board members are provided with the Board's conflict of interest questionnaire to fill out. Board members are educated on their responsibility to raise the issue of a conflict if one should arise relating to any particular topic before the Board. New and continuing Board members are then also required to fill out the Board's conflict of interest questionnaire annually at the Board's September meeting. The Board president reviews all conflict of interest questionnaires to determine whether there is any standing conflict of interest disclosed in such questionnaires.</ExplanationTxt>
