Also, the Agency performs informal inquiries of similar agencies in the community regarding compensation rates for direct service provider positions, which are typically the most difficult to fill. The Board of Directors establishes the executive director's compensation annually and approves the total agency salaries and benefits during the annual budget review. The executive director and management team, in conjunction with the personnel committee, are charged with the development of the specific positions within the agency, the job descriptions, and the appropriate salary range for each. These are reviewed by the board of directors as necessary as well as in conjunction with budget preparation. Form 990, Part VI, Section B, line 11b The executive director and director of finance assist the accounting firm with preparation of the annual Form 990. They review a draft of Form 990 for completeness and accuracy. They also review narratives describing the Agency's mission, programs, policies and procedures to ensure that they are up to date and accurate. The board president and treasurer then review the draft of Form 990, meeting with management and the accounting firm as considered necessary to resolve any questions or concerns. When their review is complete, a draft of the Form 990 is then provided to all directors, who are given time for quqestions and feedback. The board president, treasurer, management, and the accounting firm incorporate this feedback into the final 990, which is then filed with the Internal Revenue Service. Form 990, Part VI, Section B, line 12c The organization does not use a formal "annual disclosure" process to monitor compliance with the conflict of interest policy. Directors, management, and staff are expected to voluntarily disclose any activities or relationships that violate, or could potentially violate, the conflict of interest policy as soon as those situations arise. Each individual situation is assessed and resolution determined in accordance with the policy.
