Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Note 1 Basis of Presentation 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 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 June 30, 2022, are UScellular 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. All of TDS’ segments operate only in the United States. See Note 12 — Business Segment Information for summary financial information on each business segment. The unaudited consolidated financial statements included herein have been prepared by TDS pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, TDS believes that the disclosures included herein are adequate to make the information presented not misleading. 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, 2021. 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 June 30, 2022 and December 31, 2021 and its results of operations, comprehensive income and changes in equity for the three and six months ended June 30, 2022 and 2021, and its cash flows for the six months ended June 30, 2022 and 2021. 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, 2021. Software License Agreements Certain software licenses are recorded as acquisitions of property, plant and equipment and the incurrence of a liability to the extent that the license fees are not fully paid at acquisition, and are treated as non-cash activity in the Consolidated Statement of Cash Flows. Such non-cash acquisitions of software license agreements were $139 million for the six months ended June 30, 2022. Restricted Cash TDS presents restricted cash with cash and cash equivalents in the Consolidated Statement of Cash Flows. Restricted cash primarily consists of balances required under the receivables securitization agreement. See Note 9 — Debt for additional information related to the receivables securitization agreement. The following table provides a reconciliation of Cash and cash equivalents and restricted cash reported in the Consolidated Balance Sheet to the total of the amounts in the Consolidated Statement of Cash Flows. June 30, 2022 December 31, 2021 (Dollars in millions) Cash and cash equivalents $ 466 $ 367 Restricted cash included in Other current assets 39 47 Cash, cash equivalents and restricted cash in the statement of cash flows $ 505 $ 414

Contract Balances The following table provides balances for contract assets from contracts with customers, which are recorded in Other current assets and Other assets and deferred charges in the Consolidated Balance Sheet, and contract liabilities from contracts with customers, which are recorded in Customer deposits and deferred revenues and Other deferred liabilities and credits in the Consolidated Balance Sheet. June 30, 2022 December 31, 2021 (Dollars in millions) Contract assets $ 9 $ 10 Contract liabilities $ 303 $ 289 Revenue recognized related to contract liabilities existing at January 1, 2022 was $171 million for the six months ended June 30, 2022. Transaction price allocated to the remaining performance obligations The following table includes estimated service revenues expected to be recognized related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. These estimates represent service revenues to be recognized when services are delivered to customers pursuant to service plan contracts and under certain roaming agreements with other carriers. These estimates are based on contracts in place as of June 30, 2022 and may vary from actual results. 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. Service Revenues (Dollars in millions) Remainder of 2022 $ 277 2023 216 Thereafter 186 Total $ 679 Contract Cost Assets 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. Contract cost asset balances, which are recorded in Other assets and deferred charges in the Consolidated Balance Sheet, were as follows: June 30, 2022 December 31, 2021 (Dollars in millions) Costs to obtain contracts Sales commissions $ 134 $ 139 Fulfillment costs Installation costs 9 10 Total contract cost assets $ 143 $ 149 Amortization of contract cost assets was $28 million and $57 million for the three and six months ended June 30, 2022, respectively, and $29 million and $59 million for the three and six months ended June 30, 2021, respectively, and was included in Selling, general and administrative expenses and Cost of services expenses.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 3 Fair Value Measurements As of June 30, 2022 and December 31, 2021, TDS did not have any material financial or nonfinancial assets or liabilities that were required to be recorded at fair value in its Consolidated Balance Sheet in accordance with GAAP. The provisions of GAAP establish a fair value hierarchy that contains three levels for inputs used in fair value measurements. Level 1 inputs include quoted market prices for identical assets or liabilities in active markets. Level 2 inputs include quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets and liabilities in inactive markets. Level 3 inputs are unobservable. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. A financial instrument’s level within the fair value hierarchy is not representative of its expected performance or its overall risk profile and, therefore, Level 3 assets are not necessarily higher risk than Level 2 assets or Level 1 assets. TDS has applied the provisions of fair value accounting for purposes of computing the fair value of financial instruments for disclosure purposes as displayed below. Level within the Fair Value Hierarchy June 30, 2022 December 31, 2021 Book Value Fair Value Book Value Fair Value (Dollars in millions) Long-term debt Retail 2 $ 1,500 $ 1,156 $ 1,500 $ 1,594 Institutional 2 536 425 535 659 Other 2 1,486 1,486 944 944 Long-term debt excludes lease obligations, the current portion of Long-term debt and debt financing costs. The fair value of “Retail” Long-term debt was estimated using market prices for UScellular Senior Notes, which are traded on the New York Stock Exchange. TDS’ “Institutional” debt consists of UScellular’s 6.7% Senior Notes which are traded over the counter. TDS’ “Other” debt consists of term loan credit agreements, receivables securitization agreement and in 2022, export credit financing agreement. TDS estimated the fair value of its Institutional and Other debt through a discounted cash flow analysis using the interest rates or estimated yield to maturity for each borrowing, which ranged from 2.22% to 7.75% and 1.31% to 4.40% at June 30, 2022 and December 31, 2021, respectively. The fair values of Cash and cash equivalents, restricted cash and short-term debt approximate their book values due to the short-term nature of these financial instruments.

Equipment Installment Plans	Note 4 Equipment Installment Plans UScellular sells devices to customers under equipment installment plans over a specified time period. For certain equipment installment plans, after a specified period of time or amount of payments, the customer may have the right to upgrade to a new device and have the remaining unpaid equipment installment contract balance waived, subject to certain conditions, including trading in the original device in good working condition and signing a new equipment installment contract. The following table summarizes equipment installment plan receivables.

From this evaluation, a credit class is assigned to the customer that determines the number of eligible lines, the amount of credit available, and the down payment requirement, if any. These credit classes are grouped into four credit categories: lowest risk, lower risk, slight risk and higher risk. A customer's assigned credit class is reviewed periodically and a change is made, if appropriate. An equipment installment plan billed amount is considered past due if not paid within 30 days. The balance and aging of the equipment installment plan receivables on a gross basis by credit category were as follows: June 30, 2022 December 31, 2021 Lowest Risk Lower Risk Slight Risk Higher Risk Total Lowest Risk Lower Risk Slight Risk Higher Risk Total (Dollars in millions) Unbilled $ 892 $ 91 $ 22 $ 5 $ 1,010 $ 896 $ 94 $ 24 $ 5 $ 1,019 Billed — current 38 5 1 — 44 40 5 1 1 47 Billed — past due 11 6 2 1 20 10 6 2 1 19 Total $ 941 $ 102 $ 25 $ 6 $ 1,074 $ 946 $ 105 $ 27 $ 7 $ 1,085 The balance of the equipment installment plan receivables as of June 30, 2022 on a gross basis by year of origination were as follows: 2019 2020 2021 2022 Total (Dollars in millions) Lowest Risk $ 3 $ 146 $ 462 $ 330 $ 941 Lower Risk — 10 52 40 102 Slight Risk — 1 8 16 25 Higher Risk — — 3 3 6 Total $ 3 $ 157 $ 525 $ 389 $ 1,074 Activity for the six months ended June 30, 2022 and 2021, in the allowance for credit losses for equipment installment plan receivables was as follows: June 30, 2022 June 30, 2021 (Dollars in millions) Allowance for credit losses, beginning of period $ 72 $ 78 Bad debts expense 37 13 Write-offs, net of recoveries (35) (19) Allowance for credit losses, end of period $ 74 $ 72

Earnings Per Share [Abstract]
Earnings Per Share	Note 6 Earnings Per Share Basic earnings per share attributable to TDS common shareholders is computed by dividing Net income attributable to TDS common shareholders by the weighted average number of Common Shares outstanding during the period. Diluted earnings per share attributable to TDS common shareholders is computed by dividing Net income attributable to TDS common shareholders by the weighted average number of Common Shares outstanding during the period adjusted to include the effects of potentially dilutive securities. Potentially dilutive securities primarily include incremental shares issuable upon the exercise of outstanding stock options and the vesting of performance and restricted stock units. The amounts used in computing basic and diluted earnings per share attributable to TDS common shareholders were as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 (Dollars and shares in millions, except per share amounts) Net income attributable to TDS common shareholders used in basic earnings per share $ 18 $ 20 $ 61 $ 77 Adjustments to compute diluted earnings: Noncontrolling interest adjustment — — (1) (1) Net income attributable to TDS common shareholders used in diluted earnings per share $ 18 $ 20 $ 60 $ 76 Weighted average number of shares used in basic earnings per share: Common Shares 108 108 108 108 Series A Common Shares 7 7 7 7 Total 115 115 115 115 Effects of dilutive securities 1 1 1 1 Weighted average number of shares used in diluted earnings per share 116 116 116 116 Basic earnings per share attributable to TDS common shareholders $ 0.15 $ 0.18 $ 0.53 $ 0.67 Diluted earnings per share attributable to TDS common shareholders $ 0.15 $ 0.17 $ 0.52 $ 0.65 Certain Common Shares issuable upon the exercise of stock options or vesting of performance and restricted stock units were not included in weighted average diluted shares outstanding for the calculation of Diluted earnings per share attributable to TDS common shareholders because their effects were antidilutive. The number of such Common Shares excluded was 4 million for both the three and six months ended June 30, 2022, and 3 million for both the three and six months ended June 30, 2021.

UScellular paid $30 million of this amount in 2020 and the remainder in March 2021. The wireless spectrum licenses from Auction 107 were granted by the FCC in July 2021. Additionally, UScellular expects to be obligated to pay approximately $187 million in total from 2021 through 2024 related to relocation costs and accelerated relocation incentive payments. Such additional costs were accrued and capitalized at the time the licenses were granted. In October 2021, UScellular paid $36 million related to the additional costs. The spectrum must be cleared by incumbent providers before UScellular can access it. UScellular does not expect to have access to this spectrum until late 2023. In January 2022, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 380 wireless spectrum licenses in the 3.45-3.55 GHz band (Auction 110) for $580 million. UScellular paid $20 million of this amount in 2021 and the remainder in January and February 2022. The advance payment was included in Other assets and deferred charges in the December 31, 2021 Consolidated Balance Sheet. The wireless spectrum licenses from Auction 110 were granted by the FCC on May 4, 2022.

The maturity dates of the UScellular term loan agreements are July 2026, July 2028 and July 2031. In July 2022, UScellular borrowed the remaining $100 million under the term loan agreement. TDS and UScellular believe that they were in compliance with all of the financial and other covenants and requirements set forth in their term loan credit agreements as of June 30, 2022. Export Credit Financing Agreement In December 2021, UScellular entered into a $150 million term loan credit facility with Export Development Canada to finance (or refinance) equipment imported from Canada, including equipment purchased prior to entering the term loan credit facility agreement. Borrowings bear interest at a rate of SOFR plus 1.60% and are due and payable on the five-year anniversary of the first borrowing, which is in January 2027. During the six months ended June 30, 2022, UScellular borrowed $150 million, which is the full amount available under the agreement. TDS believes that UScellular was in compliance with all of the financial and other covenants and requirements set forth in their export credit financing agreement as of June 30, 2022. Receivables Securitization Agreement UScellular, through its subsidiaries, has a receivables securitization agreement for securitized borrowings using its equipment installment receivables. In March 2022, UScellular amended the agreement to extend the maturity date to March 2024. There were no significant changes to other terms of the receivable securitization agreement. Amounts under the receivables securitization agreement may be borrowed, repaid and reborrowed from time to time until the maturity date, which may be extended from time to time as specified therein. The outstanding borrowings bear interest at a rate that approximates SOFR plus 0.90%. During the six months ended June 30, 2022, UScellular repaid $150 million under the agreement. As of June 30, 2022, the outstanding borrowings under the agreement were $300 million and the unused borrowing capacity under the agreement was $150 million, subject to sufficient collateral to satisfy the asset borrowing base provisions of the agreement. As of June 30, 2022, the USCC Master Note Trust held $426 million of assets available to be pledged as collateral for the receivables securitization agreement. In July 2022, UScellular repaid $50 million under its receivables securitization agreement. TDS believes that UScellular was in compliance with all of the financial and other covenants and requirements set forth in their receivables securitization agreement as of June 30, 2022. Repurchase Agreement In January 2022, UScellular, through a subsidiary (the repo subsidiary), entered into a repurchase agreement to borrow up to $200 million, subject to the availability of eligible equipment installment plan receivables and the agreement of the lender. The transaction form involves the sale of receivables by the repo subsidiary and the commitment to repurchase at the end of the applicable repurchase term, which may extend up to one month. The transaction is accounted for as a one-month secured borrowing. The outstanding borrowings bear interest at a rate of SOFR plus 1.25%. Although the lender holds a security interest in the receivables, the repo subsidiary retains effective control and collection risk of the receivables, and therefore, any activity associated with the repurchase agreement will be treated as a secured borrowing. UScellular will continue to report equipment installment plan receivables and any related balances on the Consolidated Balance Sheet. The expiration date of the repurchase agreement is in January 2023. During the six months ended June 30, 2022, the repo subsidiary borrowed $60 million under the repurchase agreement. As of June 30, 2022, the outstanding borrowings under the agreement were $60 million and the unused borrowing capacity was $140 million. The outstanding borrowings are included in Other current liabilities in the June 30, 2022 Consolidated Balance Sheet. As of June 30, 2022, UScellular held $638 million of assets available for inclusion in the repurchase facility; these assets are distinct from the assets held by the USCC Master Note Trust for UScellular's receivables securitization agreement. In July 2022, UScellular repaid $50 million under its repurchase agreement.

Variable Interest Entities

Variable Interest Entities	6 Months Ended

Variable Interest Entities [Abstract]
Variable Interest Entities	Note 10 Variable Interest Entities Consolidated VIEs 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, 2021. UScellular formed USCC EIP LLC (Seller/Sub-Servicer), USCC Receivables Funding LLC (Transferor) and the USCC Master Note Trust (Trust), collectively the special purpose entities (SPEs), to facilitate a securitized borrowing using its equipment installment plan receivables. Under a Receivables Sale Agreement, UScellular wholly-owned, majority-owned and unconsolidated entities, collectively referred to as “affiliated entities”, transfer device equipment installment plan contracts to the Seller/Sub-Servicer. The Seller/Sub-Servicer aggregates device equipment installment plan contracts, and performs servicing, collection and all other administrative activities related to accounting for the equipment installment plan contracts. The Seller/Sub-Servicer sells the eligible equipment installment plan receivables to the Transferor, a bankruptcy remote entity, which subsequently sells the receivables to the Trust. The Trust, which is bankruptcy remote and isolated from the creditors of UScellular, will be responsible for issuing asset-backed variable funding notes (Notes), which are collateralized by the equipment installment plan receivables owned by the Trust. Given that UScellular has the power to direct the activities of these SPEs, and that these SPEs lack sufficient equity to finance their activities, UScellular is deemed to have a controlling financial interest in the SPEs and, therefore, consolidates them. All transactions with third parties (e.g., issuance of the asset-backed variable funding notes) will be accounted for as a secured borrowing due to the pledging of equipment installment plan contracts as collateral, significant continuing involvement in the transferred assets, subordinated interests of the cash flows, and continued evidence of control of the receivables. The following VIEs were formed to participate in FCC auctions of wireless spectrum licenses and to fund, establish, and provide wireless service with respect to any FCC wireless spectrum licenses won in the auctions: ▪ Advantage Spectrum, L.P. (Advantage Spectrum) and Sunshine Spectrum, Inc., the general partner of Advantage Spectrum; and ▪ King Street Wireless, L.P. (King Street Wireless) and King Street Wireless, Inc., the general partner of King Street Wireless. These particular VIEs are collectively referred to as designated entities. The power to direct the activities that most significantly impact the economic performance of these VIEs is shared. Specifically, the general partner of these VIEs has the exclusive right to manage, operate and control the limited partnerships and make all decisions to carry on the business of the partnerships. The general partner of each partnership needs the consent of the limited partner, an indirect TDS subsidiary, to sell or lease certain wireless spectrum licenses, to make certain large expenditures, admit other partners or liquidate the limited partnerships. Although the power to direct the activities of these VIEs is shared, TDS has the most significant level of exposure to the variability associated with the economic performance of the VIEs, indicating that TDS is the primary beneficiary of the VIEs. Therefore, in accordance with GAAP, these VIEs are consolidated. TDS also consolidates other VIEs that are limited partnerships that provide wireless service. A limited partnership is a variable interest entity unless the limited partners hold substantive participating rights or kick-out rights over the general partner. For certain limited partnerships, UScellular is the general partner and manages the operations. In these partnerships, the limited partners do not have substantive kick-out or participating rights and, further, such limited partners do not have the authority to remove the general partner. Therefore, these limited partnerships also are recognized as VIEs and are consolidated under the variable interest model. The following table presents the classification and balances of the consolidated VIEs’ assets and liabilities in TDS’ Consolidated Balance Sheet. June 30, 2022 December 31, 2021 (Dollars in millions) Assets Cash and cash equivalents $ 30 $ 22 Accounts receivable 686 692 Inventory, net 3 2 Other current assets 35 44 Licenses 638 637 Property, plant and equipment, net 110 108 Operating lease right-of-use assets 41 42 Other assets and deferred charges 379 382 Total assets $ 1,922 $ 1,929 Liabilities Current liabilities $ 89 $ 28 Long-term operating lease liabilities 37 37 Other deferred liabilities and credits 26 23 Total liabilities 1 $ 152 $ 88 1 Total liabilities does not include amounts borrowed under the receivables securitization agreement. See Note 9 – Debt for additional information. Unconsolidated VIEs TDS manages the operations of and holds a variable interest in certain other limited partnerships, but is not the primary beneficiary of these entities and, therefore, does not consolidate them under the variable interest model. TDS’ total investment in these unconsolidated entities was $5 million and $4 million at June 30, 2022 and December 31, 2021, respectively, and is included in Investments in unconsolidated entities in TDS’ Consolidated Balance Sheet. The maximum exposure from unconsolidated VIEs is limited to the investment held by TDS in those entities. Other Related Matters TDS made contributions, loans or advances to its VIEs totaling $101 million and $50 million, during the six months ended June 30, 2022 and 2021, respectively, of which $80 million in 2022 and $21 million in 2021, are related to USCC EIP LLC as discussed above. TDS may agree to make additional capital contributions and/or advances to these or other VIEs and/or to their general partners to provide additional funding for operations or the development of wireless spectrum licenses granted in various auctions. TDS may finance such amounts with a combination of cash on hand, borrowings under its revolving credit or receivables securitization agreements and/or other long-term debt. There is no assurance that TDS will be able to obtain additional financing on commercially reasonable terms or at all to provide such financial support. The limited partnership agreement of Advantage Spectrum also provides the general partner with a put option whereby the general partner may require the limited partner, a subsidiary of UScellular, to purchase its interest in the limited partnership. In June 2022, the limited partnership agreement was amended and the general partner’s put option related to its interest in Advantage Spectru m will now be exercisable in the third quarter of 2023, and if not exercised at that time, will be exercisable in the third quarter of 2024. The greater of the carrying value of the general partner's investment or the value of the put option, net of any borrowings due to TDS, is recorded as Noncontrolling interests with redemption features in TDS’ Consolidated Balance Sheet. Also in accordance with GAAP, minority share of income or changes in the redemption value of the put option, net of interest accrued on the loans, are recorded as a component of Net income attributable to noncontrolling interests, net of tax, in TDS’ Consolidated Statement of Operations.

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 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 June 30, 2022, are UScellular 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. All of TDS’ segments operate only in the United States. See Note 12 — Business Segment Information for summary financial information on each business segment.
Basis of Accounting	The unaudited consolidated financial statements included herein have been prepared by TDS pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, TDS believes that the disclosures included herein are adequate to make the information presented not misleading. 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, 2021. 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 June 30, 2022 and December 31, 2021 and its results of operations, comprehensive income and changes in equity for the three and six months ended June 30, 2022 and 2021, and its cash flows for the six months ended June 30, 2022 and 2021. 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, 2021.
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.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, 2021.
