        <ExplanationTxt>The Museum has a conflict of interest policy in which each board member, officer, staff member, and volunteer receives a copy at the beginning of their term of service. They are required to review, sign and date the policy at that time, and then on an annual basis, disclosing any potential conflicts. The Board of Directors reviews any potential conflicts and makes the determination as to whether an actual conflict of interest exists. An interested person may make a presentation to the Board, but after the presentation, they must leave the meeting and cannot participate in any discussion or debate pertaining to the transaction. If necessary, the President of the Board may appoint a disinterested person or committee to investigate alternatives to the proposed transaction or arrangement. If a more advantageous transaction or arrangement is not reasonably possible in circumstances not producing a conflict of interest, the Board will determine, by a majority vote of disinterested members, whether the transaction or arrangement is in the Museum's best interest. If the Board has reason to believe a person has failed to disclose a potential or actual conflict of interest, it informs the person of the basis for their belief and allows them an opportunity to explain the alleged failure to disclose. If it is determined that the person failed to disclose a potential or actual conflict of interest, the Board will take appropriate disciplinary and corrective action. The deliberations and decisions related to these matters are documented within the minutes of the applicable meeting.</ExplanationTxt>
