        <ExplanationTxt>The School follows FASB ASC 740, Income Taxes, which clarifies the accounting for uncertain income tax positions 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 uncertain tax positions as of June 30, 2020 or 2019. Aside from exceptional circumstances (such as fraud), the School is only subject to income tax examinations by the US federal or local tax authorities for three years from the filing date. The School will account for interest and penalties related to uncertain tax positions, if any, as part of tax expense.</ExplanationTxt>

        <ExplanationTxt>The School works directly with town officials and local charitable organizations to assess future needs and the use of current and past monetary grants. The School also makes several other small donations throughout the year based on the charitable purpose, historical relationship, and current need. These one-time contributions are not typically monitored by the CFO or Headmaster. Financial aid grants are awarded annually to qualified students and are typically applied as credits to the tuition bill up to the amount of the grant for the current academic year. In some instances, cash payments are issued directly to parents as reimbursements for academic expenses or travel related costs when applicable.</ExplanationTxt>

        <ExplanationTxt>Faculty are required to live in on-campus housing as a condition of employment. The Headmaster's home includes some space that is reserved for School related meetings and student activities. The cost of maintaining this allotted space is paid by the School and recorded as an operating expense. The Headmaster's contract, which is approved by the Board President and the Compensation Committee, includes the cost of residential cleaning. The cost is recorded by the School as a taxable benefit and reported on the W-2. The School will only pay for the cost of a traveling spouse when they are an authorized participant in School related functions. In such a case, the cost is treated as a non-taxable work-related event. The discretionary account is provided to the Headmaster as part of the approved annual budget. The account is used to fund small School related expenses and, as a result, is not reported as a taxable fringe benefit.</ExplanationTxt>
