Discontinued Operations and Disposal Groups [Abstract]
Wireline	Note 14 – Wireline Sale of the Wireline Business On September 6, 2022, two of our wholly owned subsidiaries, Sprint Communications and Sprint LLC, and Cogent Infrastructure, Inc., entered into the Wireline Sale Agreement, pursuant to which the Buyer agreed to acquire the Wireline Business. The Wireline Sale Agreement provided that, upon the terms and conditions set forth therein, the Buyer agreed to purchase all of the issued and outstanding membership interests (the “Purchased Interests”) of a Delaware limited liability company that holds certain assets and liabilities relating to the Wireline Business. On May 1, 2023, pursuant to the Wireline Sale Agreement, upon the terms and subject to the conditions thereof, we completed the Wireline Transaction. Under the terms of the Wireline Sale Agreement, the parties agreed to a $1 purchase price in consideration for the Purchased Interests, subject to customary adjustments, as well as payments to the Buyer pursuant to an IP transit services agreement totaling $700 million, consisting of (i) $350 million in equal monthly installments during the first year after the Closing and (ii) $350 million in equal monthly installments over the subsequent 42 months. The Buyer paid the Company $61 million at Closing. The Closing of the Wireline Transaction did not have a significant impact on the (Gain) loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income. The present value of the $700 million liability for fees payable for IP transit services was recognized and treated as part of the consideration exchanged with the Buyer to complete the disposal transaction, as there is a remote likelihood we will use any more than a de minimis amount of the services under the IP transit services agreement. Therefore, we concluded the cash payment obligations under the IP transit services agreement were part of the consideration paid to the Buyer to facilitate the sale of the Wireline Business, and therefore, included in measuring the fair value less costs to sell of the Wireline Business disposal group. As of December 31, 2023, $183 million and $255 million of this liability, including accrued interest, is presented within Other current liabilities and Other long-term liabilities, respectively, on our Consolidated Balance Sheets in accordance with the expected timing of the related payments. We recognized a pre-tax gain of $25 million during the year ended December 31, 2023, and a pre-tax loss of $1.1 billion during the year ended December 31, 2022, which are included within (Gain) loss on disposal group held for sale on our Consolidated Statements of Comprehensive Income. We do not consider the sale of the Wireline Business to be a strategic shift that will have a major effect on the Company’s operations and financial results, and therefore it does not qualify for reporting as a discontinued operation. Other Wireline Asset Sales Separate from the Wireline Transaction, we recognized a gain on disposal of $121 million during the year ended December 31, 2022, all of which relates to the sale of certain IP addresses held by the Wireline Business to other third parties during the three months ended September 30, 2022. The gain on disposal is included as a reduction to Selling, general and administrative expense on our Consolidated Statements of Comprehensive Income. Wireline Impairment Prior to the closing of the Wireline Transaction, we provided wireline communication services to domestic and international customers via the legacy Sprint Wireline U.S. long-haul fiber network (including non-U.S. extensions thereof). The legacy Sprint Wireline network was primarily comprised of owned property and equipment, including land, buildings, communication systems and data processing equipment, fiber optic cable and operating lease right-of-use assets. Previously, the operation of the legacy Sprint CDMA and LTE wireless networks was supported by the legacy Sprint Wireline network. During the second quarter of 2022, we retired the legacy Sprint CDMA network and began the orderly shut-down of the LTE network. We assess long-lived assets for impairment when events or circumstances indicate that they might be impaired. During the second quarter of 2022, we determined that the retirement of the legacy Sprint CDMA and LTE wireless networks triggered the need to assess the Wireline long-lived assets for impairment, as these assets no longer supported our wireless network and the associated customers and cash flows in a significant manner. In evaluating whether the Wireline long-lived assets were impaired, we estimated the fair value of these assets using a combination of the cost, income and market approaches, including market participant assumptions. The fair value measurement of the Wireline assets was estimated using significant inputs not observable in the market (Level 3). The results of this assessment indicated that certain Wireline long-lived assets were impaired, and as a result, we recorded non-cash impairment expense of $477 million during the year ended December 31, 2022, all of which relates to the impairment recognized during the three months ended June 30, 2022, of which $258 million is related to Wireline Property and equipment, $212 million is related to Operating lease right-of-use assets and $7 million is related to Other intangible assets. In measuring and allocating the impairment expense to individual Wireline long-lived assets, we did not impair the long-lived assets below their individual fair values. The expense is included within Impairment Expense on our Consolidated Statements of Comprehensive Income. There was no impairment expense recognized for the year ended December 31, 2023.
