        <Explanation>The conflict of interest policy was originally approved by the board in 2004 and was most recently amended in March of 2008. The policy is distributed at the beginning of each year to all board members, as well as all employees with purchasing responsibility. The policy is included in the board of trustees manual and the employee policies and procedures manual. The policy requires the disclosure of any compensation received from the organization and any relationships with related parties (reported in Form 990 Part V-A and Schedule O). At each committee and board meeting, members are expected to comply with the policy. Any board members with a potential conflict of interest are expected to recuse themselves from any relevant issue and the recusal is reflected in the minutes of that meeting.</Explanation>
