Divestitures [Abstract]
Divestitures	Note 6 Divestitures On August 4, 2023, TDS and Array announced that the Boards of Directors of both companies decided to initiate a process to explore a range of strategic alternatives for Array. On May 28, 2024, Array announced that its Board of Directors unanimously approved the execution of a Securities Purchase Agreement (Securities Purchase Agreement) by and among TDS, Array, T-Mobile US, Inc. (T-Mobile) and USCC Wireless Holdings, LLC, pursuant to which, among other things, Array agreed to sell its wireless operations and select spectrum assets to T-Mobile. The Securities Purchase Agreement also contemplated, among other things, a Short-Term Spectrum Manager Lease Agreement and Short-Term Spectrum Manager Sublease Agreements that would become effective at the closing date, which provide T-Mobile with an exclusive license to use certain Array spectrum assets and leases at no cost for up to one-year for the sole purpose of providing continued, uninterrupted service to customers. The sale of the wireless operations to T-Mobile was subject to the receipt of regulatory approvals and the satisfaction of customary closing conditions. As of June 30, 2025, the transaction did not meet the accounting criteria to be presented as discontinued operations. On October 17, 2024, Array, and certain subsidiaries of Array, entered into a License Purchase Agreement (Verizon Purchase Agreement) with Verizon Communications Inc. (Verizon) to sell certain AWS, Cellular and PCS wireless spectrum licenses and agreed to grant Verizon certain rights to lease such licenses prior to the transaction close for total proceeds of $1,000 million. As of June 30, 2025, the book value of the wireless spectrum licenses to be sold was $586 million. The transaction is expected to close in the third quarter of 2026, subject to regulatory approval and other customary closing conditions, and the termination of the T-Mobile Short-Term Spectrum Manager Lease Agreement. On November 6, 2024, Array, and certain subsidiaries of Array, entered into a License Purchase Agreement (AT&T Purchase Agreement) with New Cingular Wireless PCS, LLC (AT&T), a subsidiary of AT&T Inc. to sell certain 3.45 GHz and 700 MHz wireless spectrum licenses and agreed to grant AT&T certain rights to lease and sub-lease such licenses prior to the transaction close for total proceeds of $1,018 million, subject to certain purchase price adjustments. As of June 30, 2025, the book value of the wireless spectrum licenses to be sold was $860 million. The transaction is expected to close in 2025, subject to regulatory approval and other customary closing conditions. The strategic alternatives review process is ongoing as Array works toward closing the Verizon and AT&T spectrum transactions signed during 2024, and continues to seek to opportunistically monetize its spectrum assets that are not subject to the Securities Purchase Agreement, the Verizon Purchase Agreement, or the AT&T Purchase Agreement. Array incurred third-party expenses related to the announced transactions and strategic alternatives review of $12 million and $22 million for the three and six months ended June 30, 2025, respectively, and $13 million and $21 million for the three and six months ended June 30, 2024, respectively, which are included in Selling, general and administrative expenses. As part of the transaction, Array entered into a Put/Call Agreement with T-Mobile whereby T-Mobile has the right to call certain spectrum assets and Array has the right to put certain spectrum assets to T-Mobile for an aggregate agreed upon price of $106 million. The call option notice period started on May 24, 2024, and the put exercise period starts at the close of the broader transaction. There was no cash exchanged at the inception of the Put/Call Agreement. All license transfers pursuant to any put/call are subject to Federal Communications Commission (FCC) approval. Array accounts for this instrument as a net written call option and records such option at fair value each reporting period unless/until such option is exercised or terminated. As of June 30, 2025, Array wrote off the entire fair value of the net written call option. The change in fair value is recorded to (Gain) loss on license sales and exchanges, net in the Consolidated Statement of Operations.
