      <ExplanationTxt>The Turnbull Family Foundation is registered as a charitable organization in the State of Delaware. Delaware has an annual franchise tax report that the Foundation files each year but does not require a copy of the Foundation's return to be sent to the AG's office.</ExplanationTxt>
    </ExplnOfNonFilingWithAGStmt>
    <LiquidationExplanationStmt documentId="RetDoc2210900001">
      <ExplanationTxt>Effective December 22, 2023, the Board of the Foundation authorized its unanimous written consent to voluntarily dissolve the Corporation in accordance with Section 276(a) of the General Corporation Law of the State of Delaware. The Foundation's Certificate of Dissolution has also been filed with the State of Delaware as of the filing of this Form 990-PF. There being no members of the Corporation other than the members of the Board, no separate vote of the membership is required to approve this dissolution, and no approval of the dissolution of the Corporation is required by any government agency or officer. As of the time of the Corporation's Consent to Dissolve, the Corporation's remaining assets were $284,754.36. The Corporation made grants in the amounts of $200,000 to New York University (EIN: 13-5562308) and $75,000 to the College of the Atlantic (EIN: 23-7032625), both nonprofit corporations and public charities exempt under Section 501(c)(3) of the Internal Revenue Code (the "Code"), to be used for exempt purposes within the meaning of Section 501(c)(3) of the Code. Such final donations were paid in addition to other charitable gifts made during the year but prior to the Corporation's Consent to Dissolve. The Corporation's remaining assets after such grants were used for expenses associated with dissolving the Corporation and winding up its affairs. Immediately after each of the aforementioned transfers, and as of the close of this tax year (year ending December 31, 2023), the Foundation retained no legal right, title, or interest in any asset. Accordingly, the Foundation has no remaining assets and has checked the box declaring this to be a final return.</ExplanationTxt>
