“The Head of the Junior Program is the spouse of the President.”
“The organization has a Board of Trustees who may elect one or more persons to the Board of Trustees.”
“Form 990 is first prepared by the Business Manager, reviewed by the President of the organization and the outside auditors. The return is then reviewed by the Audit Commitee and finally submitted for approval to the Board of Trustees.”
“Form 990 Page 6,line 12b - Officers, directors, trustees or key employes are required to disclose annually any interests because it is important for management and the board of directors to be aware of any potential conflicts.”
“Form 990 Page 6, line 15a - The process of determining compensation for the organization's president included an independent review and approval by the organization's compensation committee. The compensation committee, along with the assistance of an independent compensation consultant, reviewed comparability data in determining the president's salary as the organization deems it good practice to use third party independent information in determining compensation.”
“No documents available to the public”
“The intended uses of the organization's endowment funds are for scholarships.”
“In accordance with Section 501(c)(3) of the Internal Revenue Code, the School is exempt from federal and state income taxes and, accordingly, the financial statements do not reflect a provision for income taxes. These determinations have been reviewed according to guidance in a Financial Accounting Standards Board pronouncement related to accounting for uncertainty in income taxes. In determining the recognition of uncertain tax positions, the School applies a more-likely-than-not recognition threshold and determines the measurement of uncertain tax positions considering the amounts and probabilities of the outcomes that could be realized upon ultimate settlement with taxing authorities. As of August 31, 2018, the School has no uncertain tax positions that qualify for either recognition or disclosure in the financial statements.”
