Purchases of art objects by the Museum would be separately identified as decreases in net assets in the Statements of Activities. It is the Museum's policy to designate proceeds from the sale of art for the acquisition of art.

The person involved in the potential conflict is required to leave the board meeting or committee meeting while the issue is discussed and voted upon. All employees of the Museum are also required to annually disclose any actual or possible conflicts of interest. These disclosures are reviewed by senior management.</ExplanationTxt>
