Mergers, Acquisitions and Dispositions Disclosures [Text Block]	NOTE 8. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS Fiber On February 2, 2026, we acquired substantially all of Lumen’s Mass Markets fiber business for $5,756, including purchase price adjustments. The preliminary values of assets acquired were approximately $900 in customer relationships, $3,400 in property, plant and equipment, and $800 of goodwill. The customer relationships are managed in our Advanced Connectivity segment and will be amortized using the sum-of-the-months method over six years. Property, plant and equipment primarily represent the acquired fiber network, which we placed in Forged Fiber, a wholly owned subsidiary. In connection with this transaction, we plan to sell a controlling interest in Forged Fiber to an equity partner that will co-invest in the ongoing business. As such, Forged Fiber met the criteria of held-for-sale and accordingly is reflected as discontinued operations. These discontinued operations include the fiber network assets, which support the acquired customer relationships through intercompany transactions. The discontinued operations were also assigned a proportionate share of goodwill and acquisition costs and related cash flows. (See Note 12)
