Note: Totals may not foot due to rounding differences.

(1)

TDS has re-evaluated internal reporting roles with regard to its HMS business unit and, as a result, has changed its reportable segments. Effective January 1, 2018, HMS is no longer reported under TDS Telecom. Prior periods have been recast to conform to the revised presentation.

(2)

The TDS column includes U.S. Cellular, TDS Telecom and also the impacts of consolidating eliminations, corporate operations and non-reportable segments (including HMS as indicated in Note (1) above).

(3)

As of January 1, 2018, TDS adopted the new revenue recognition standard, ASC 606, using a modified retrospective approach. Under this method, the new accounting standard is applied only to the most recent period presented. As a result, 2018 amounts include the impacts of ASC 606, but 2017 amounts remain as previously reported, except as specifically stated.

(4)

EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as net income adjusted for the items set forth in the reconciliation above. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under Generally Accepted Accounting Principles in the United States (GAAP) and should not be considered as alternatives to Net income or Cash flows from operating activities, as indicators of cash flows or as measures of liquidity. TDS does not intend to imply that any such items set forth in the reconciliation above are non-recurring, infrequent or unusual; such items may occur in the future. Management uses Adjusted EBITDA and Adjusted OIBDA as measurements of profitability, and therefore reconciliations to Net income are deemed appropriate. Management believes Adjusted EBITDA and Adjusted OIBDA are useful measures of TDS' operating results before significant recurring non-cash charges, gains and losses, and other items as presented above as they provide additional relevant and useful information to investors and other users of TDS' financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management's evaluation of business performance. Adjusted EBITDA shows adjusted earnings before interest, taxes, depreciation, amortization and accretion, and gains and losses, while Adjusted OIBDA reduces this measure further to exclude Equity in earnings of unconsolidated entities and Interest and dividend income in order to more effectively show the performance of operating activities excluding investment activities. The table above reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measure, Net income or Income (loss) before income taxes.

(5)

Additional information and reconciliations related to Non-GAAP financial measures for September 30, 2018, can be found on TDS' website at investors.tdsinc.com.

(6)

ASU 2017-07, regarding net periodic pension cost and net periodic postretirement benefit cost was adopted as of January 1, 2018, and applied retrospectively. All prior period numbers have been recast to conform to this standard.

As of January 1, 2018, U.S. Cellular adopted the new revenue recognition standard, ASC 606, using a modified retrospective approach.

As a result, 2018 amounts include the impacts of ASC 606, but 2017 amounts remain as previously reported.

(2)

Average Revenue Per User (ARPU) - metric is calculated by dividing a revenue base by an average number of connections and by the number of months in the period. These revenue bases and connection populations are shown below:

• Postpaid ARPU consists of total postpaid service revenues and postpaid connections.

• Prepaid ARPU consists of total prepaid service revenues and prepaid connections.

(3)

Average Billings Per User (ABPU) - non-GAAP metric is calculated by dividing total postpaid service revenues plus equipment installment plan billings by the average number of postpaid connections and by the number of months in the period. Refer to the end of this release for a reconciliation of this metric to its most comparable GAAP metric.

(4)

Average Revenue Per Account (ARPA) - metric is calculated by dividing total postpaid service revenues by the average number of postpaid accounts and by the number of months in the period.

(5)

Average Billings Per Account (ABPA) - non-GAAP metric is calculated by dividing total postpaid service revenues plus equipment installment plan billings by the average number of postpaid accounts and by the number of months in the period. Refer to the end of this release for a reconciliation of this metric to its most comparable GAAP metric.

(6)

Churn rate represents the percentage of the connections that disconnect service each month. These rates represent the average monthly churn rate for each respective period.

(7)

Includes reseller and other connections.

(8)

Market penetration is calculated by dividing the number of wireless connections at the end of the period by the total population of consolidated operating markets as estimated by Nielsen.

(1)

As of January 1, 2018, TDS adopted the new revenue recognition standard, ASC 606, using a modified retrospective approach. Under this method, the new accounting standard is applied only to the most recent period presented. As a result, 2018 amounts include the impacts of ASC 606, but 2017 amounts remain as previously reported, except as specifically stated.

(2)

TDS has re-evaluated internal reporting roles with regard to its HMS business unit and, as a result, has changed its reportable segments. Effective January 1, 2018, HMS is no longer reported under TDS Telecom. Prior periods have been recast to conform to the revised presentation.

(3)

Consists of TDS corporate, intercompany eliminations and all other business operations not included in the U.S. Cellular and TDS Telecom segments.

(4)

During the three months ended September 30, 2017, U.S. Cellular recorded a goodwill impairment of $370 million while TDS recorded a goodwill impairment of the U.S. Cellular reporting unit of $227 million. Prior to 2009, TDS accounted for U.S. Cellular's share repurchases as step acquisitions, allocating a portion of the share repurchase value to TDS' Goodwill. Further, goodwill of the U.S. Cellular reporting unit was impaired at the TDS level in 2003 but not at U.S. Cellular. Consequently, U.S. Cellular's goodwill on a stand-alone basis and any resulting impairments of goodwill does not equal the TDS consolidated goodwill related to U.S. Cellular. The TDS adjustment of $143 million is included in "All other". During the three months ended September 30, 2017, TDS also recorded a goodwill impairment of $35 million related to its HMS operations included in "All other".

(5)

ASU 2017-07, regarding net periodic pension cost and net periodic postretirement benefit cost was adopted January 1, 2018, and applied retrospectively. All prior period numbers have been recast to conform to this standard.
