“The trust established under the plan to hold the plan's net assets is qualified pursuant to §501(c)(9) of the irc. Tds has obtained a tax exemption letter from the internal revenue service dated august 31, 1995 and the plan sponsor believes the trust continues to qualify and operate in accordance with applicable provisions of the irc. Management evaluated the plan's tax positions and concluded that the plan had maintained its tax-exempt status and had taken no uncertain tax positions that require adjustment to the financial statements. Therefore, no provision or liability for income taxes has been included in the financial statements as of december 31, 2024 or 2023, except for the unrelated business income tax noted below. The plan is subject to audits by taxing jurisdictions; however, for tax periods in progress, there have been no such audits. The trust is subject to income tax on unrelated business income earned by the trust. For the year ended december 31, 2024, the trust recorded unrelated business income tax benefit of less than $0.1 million.”
