Accounting Policy Disclosures [Line Items] |
Principles of Consolidation | The accounting policies of Telephone and Data Systems, Inc. (TDS) conform to accounting principles generally accepted in the United States of America (GAAP) as set forth in the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC). Unless otherwise specified, references to accounting provisions and GAAP in these notes refer to the requirements of the FASB ASC. The consolidated financial statements include the accounts of TDS and subsidiaries in which it has a controlling financial interest, including TDS’ 83%-owned subsidiary, United States Cellular Corporation (UScellular) and TDS’ wholly-owned subsidiary, TDS Telecommunications LLC (TDS Telecom). In addition, the consolidated financial statements include certain entities in which TDS has a variable interest that requires consolidation into the TDS financial statements under GAAP. Intercompany accounts and transactions have been eliminated. TDS’ business segments reflected in this Quarterly Report on Form 10-Q for the period ended September 30, 2024, are UScellular Wireless, UScellular Towers and TDS Telecom. TDS’ non-reportable other business activities are presented as “Corporate, Eliminations and Other”, which includes the operations of TDS’ wholly-owned hosted and managed services (HMS) subsidiary, which operates under the OneNeck IT Solutions brand, and its wholly-owned subsidiary Suttle-Straus, Inc. (Suttle-Straus). HMS’ and Suttle-Straus’ financial results were not significant to TDS’ operations. The HMS operations were sold to a third-party on September 3, 2024. See Note 7 — Divestitures for additional information. All of TDS’ segments operate only in the United States. See Note 14 — Business Segment Information for summary financial information on each business segment.
Basis of Accounting | Certain numbers included herein are rounded to millions for ease of presentation; however, certain calculated amounts and percentages are determined using the unrounded numbers. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in TDS’ Annual Report on Form 10-K (Form 10-K) for the year ended December 31, 2023. The accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring items, unless otherwise disclosed) necessary for the fair statement of TDS’ financial position as of September 30, 2024 and December 31, 2023, its results of operations and changes in equity for the three and nine months ended September 30, 2024 and 2023, and its cash flows for the nine months ended September 30, 2024 and 2023. The Consolidated Statement of Comprehensive Income was not included because comprehensive income for the three and nine months ended September 30, 2024 and 2023, doesn't materially differ from net income. These results are not necessarily indicative of the results to be expected for the full year. TDS has not changed its significant accounting and reporting policies from those disclosed in its Form 10-K for the year ended December 31, 2023.
Revenue from Contract with Customer | As practical expedients, revenue related to contracts of less than one year, generally month-to-month contracts, and contracts with a fixed per-unit price and variable quantity, are excluded from these estimates. A significant portion of TDS Telecom's residential revenue is derived from customers who may generally cancel their subscriptions at any time without penalty. For these contracts, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from TDS Telecom's existing customer base and therefore is excluded from these estimates. TDS expects that commission fees paid as a result of obtaining contracts are recoverable, and therefore TDS defers and amortizes these costs. As a practical expedient, costs with an amortization period of one year or less are expensed as incurred. TDS also incurs fulfillment costs, such as installation costs, where there is an expectation that a future benefit will be realized. Deferred commission fees and fulfillment costs are amortized based on the timing of transfer of the goods or services to which the assets relate, typically the contract term.
Variable Interest Entities | TDS consolidates VIEs in which it has a controlling financial interest as defined by GAAP and is therefore deemed the primary beneficiary. TDS reviews the criteria for a controlling financial interest at the time it enters into agreements and subsequently when events warranting reconsideration occur. These VIEs have risks similar to those described in the “Risk Factors” in this Form 10-Q and TDS’ Form 10-K for the year ended December 31, 2023.

- Definition Disclosure of accounting policy for consolidation to describe the significant judgments and assumptions made in determining whether a variable interest held by the entity requires the variable interest entity to be consolidated and (or) disclose information about its involvement with the variable interest entity; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; and the significant factors considered and judgments made in determining that the power to direct the activities that significantly impact the economic performance of the variable interest entity are shared (as defined). + References Reference 1: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 810 -SubTopic 10 -Paragraph 2AA -Subparagraph (a) -Section 50 -Publisher FASB -URI https://asc.fasb.org/1943274/2147481203/810-10-50-2AA Reference 2: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 810 -SubTopic 10 -Section 50 -Paragraph 4 -Subparagraph (e) -Publisher FASB -URI https://asc.fasb.org/1943274/2147481203/810-10-50-4 Reference 3: http://fasb.org/us-gaap/role/ref/legacyRef -Name Accounting Standards Codification -Topic 810 -SubTopic 10 -Section 50 -Paragraph 5A -Subparagraph (a) -Publisher FASB -URI https://asc.fasb.org/1943274/2147481203/810-10-50-5A + Details
