“The organization is exempt from federal income tax under section 501(c)(3) of the u.s. Internal revenue code. The organization is not considered a private foundation by the internal revenue service. The organization does not consider any of its support and revenues to be unrelated business income and, accordingly, no provision for income taxes has been provided in the accompanying financial statements. The organization has implemented accounting for uncertainty in income taxes in accordance with u.s. Gaap. This standard describes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on various related matters such as derecognizing, interest, penalties and disclosures required. Management of the organization evaluates the uncertain tax positions taken, if any, and consults with outside counsel as deemed necessary. The organization recognizes interest and penalties, if any, related to unrecognized tax liabilities in income tax expense. In management's opinion, the organization has not taken any uncertain tax positions and, accordingly, has not reported a corresponding liability in the organization's financial statements.”
