        <Explanation>MICDS has determined that the Head of School and the Chief Financial Officer are positions that qualify as "disqualified persons". In order to establish that the compensation and benefits provided to these two individuals are reasonable and do not constitute excess benefit transactions, the Compensation Committee of the Board of Trustees performs a review in May or June to approve the compensation packages for the following school year.The Compensation Committee reviews all proposed salaries, bonuses, and benefits for the Head of School and the Chief Financial Officer. These salaries and benefits are compared to compensation for similar positions at other independent schools, considered by the School as peer schools nationally, with similar size, grades, and complexity as MICDS. The meeting is documented by the committee with written minutes. The proposed compensation packages are presented to the Board of Trustees for approval.</Explanation>
