      <FactsAndCircumstancesTestTxt>$82,618,486 million (USD)In 2023, MSI-US excluded a testamentary bequest of $82,618,486 million (USD) from public support as an "unusual grant." The bequest includes norestriction or limitation on its use.The bequest was unexpected because the individual never notified MSI-US that MSI-US would be the beneficiary of decedent's testamentary estate.Although the decedent contributed a total of $1.6 million (USD) from 2016 to 2022, the decedent never engaged directly with anyone fromMSI-US on the phone or in person. Rather, the decedent at one point requested that they not be contacted in response to a thank-you e-mailsent by MSI-US . The decedent was not an officer, director, employee, or contractor of MSI-US. Furthermore, to MSI-US's best knowledge, thedecedent was not related to any current or former MSI-US officers, directors, employees, or contractors. Thus, MSI-US had no reason toexpect that it would be the recipient of the remainder of decedent's substantial testamentary estate.The decedent's decision (when living) to make a testamentary bequest to MSI-US, without MSI-US's knowledge, demonstrates that the bequest wasmade because of MSI-US's publicly supported nature. However, because the large size and the contribution source, including the bequest inpublic support adversely affects MSI-US's public support percentage in 2023 and would continue to adversely affect MSI-US's public supportpercentage for the next five years. Accordingly, MSI-US has excluded the bequest from public support as an unusual grant in accordance withTreas. Reg. sec. 1.170A-9(f)(6)(ii).</FactsAndCircumstancesTestTxt>
