        <Explanation>The School follows FASB ASC 740, "Income Taxes", which clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The School recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities. Management evaluated the School's tax positions and concluded that the School had no material uncertainties in income taxes as of June 30, 2013 and 2012. The School is no longer subject to income tax examinations by the U.S. federal, state or local tax authorities for fiscal years before 2010. The School will account for interest and penalties related to uncertain tax positions, if any, as part of tax expense.</Explanation>
