        <ExplanationTxt>The Institute is exempt from income tax under Section 501(c)(3) of the Internal Revenue Code (the Code). In addition, the Institute qualifies for the charitable contribution deduction under Section 170(b)(1)(A) and has been classified as an organization other than a private foundation under Section 509(a)(2) of the Code. U.S. generally accepted accounting principles (U.S. GAAP) require management to evaluate tax positions taken by the Institute and recognize a liability if the Institute has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service and state taxing authorities. The Institute is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.</ExplanationTxt>
