        <ExplanationTxt>Each fiscal year, the Institute is authorized to expend from the Scholarship Fund (endowment) an amount equal to four and one-half percent of the principal of the endowment as of the first business day of such year, or such other amount as shall be mutually agreed upon by the donor or the donor's designated representatives and the Ross School. The endowment payout shall be paid first from the income of the endowment and, if and to the extent that such income is insufficient, from the principal of the endowment. If the income of the endowment in any fiscal year exceeds the authorized payout amount for such year, the excess will be added to principal at the end of such fiscal year. The endowment payout for each fiscal year shall be used to award scholarships to help support the tuition for one or more students at the Institute entering the ninth grade who have exhibited a deep interest in or enjoyment of the arts and/or sciences, especially the environmental science, and who are eligible on a needs basis for financial aid at the Institute.</ExplanationTxt>
