“The organization does not have any committees with authority to act on behalf of the governing body.”
“The prepared form 990 is reviewed by the members of the governing body before the return is filed with the irs.”
“The organization's conflict of interest policy covers all directors and employees. Any director or employee is considered an interested person. In connection with any actual or possible conflict of interest, the interested person must disclose all material facts to the executive director. If the executive director determines that a conflict of interest may exist, it is presented to the board of directors. If a conflict that may affect the daily or long-term operations of the organization is identified, either the conflict is removed or the person is asked to no longer serve in such capacity. If a conflict is noted pertaining to an employee, that person will not serve or sit on committees that pertain to personnel issues.”
“The members of the governing body determine the executive director's compensation using data on compensation paid by comparable organizations for similar services. The governing body's determination of compensation and decision are documented in the minutes of the meetings of the governing body. The process was last undertaken in 2023.”
“The organization makes its governing documents, conflict of interest policy, and financial statements available to the public upon request.”
