        <Identifier>Description of Uncertain Tax Positions Under FIN 48:</Identifier>
        <ReturnReference>Part X:</ReturnReference>
        <Explanation>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 recent Financial Accounting Standards Board pronouncement related to accounting for uncertainty in income taxes. In determining the recognition of uncertain tax positions, the School now 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 the ultimate settlement with taxing authorities. As of June 30, 2011, the School has no uncertain tax positions that qualify for either recognition in or disclosure in the financial statements.</Explanation>
