QWEST CORP

Our consolidated financial statements are prepared in accordance with accounting principles that are generally accepted in the United States. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of our assets, liabilities, revenue and expenses. We have identified certain policies and estimates as critical to our business operations and the understanding of our past or present results of operations related to (i) goodwill and other intangible assets, (ii) affiliate transactions and (iii) income taxes. These policies and estimates are considered critical because they had a material impact, or they have the potential to have a material impact, on our consolidated financial statements and because they require us to make significant judgments, assumptions or estimates. We believe that our estimates, judgments and assumptions made when accounting for the items described below were reasonable, based on information available at the time they were made. However, actual results may differ from those estimates, and these differences may be material.

Goodwill and Other Intangible Assets

We have a significant amount of goodwill that is assessed at least annually for impairment. At December 31, 2024, goodwill and intangible assets totaled $7.0 billion, or 41%, of our total assets. The impairment analyses of these assets are considered critical because of their significance to us and our segments and the subjective nature of certain assumptions used to estimate fair value.

Intangible assets arising from business combinations, such as goodwill and capitalized software are initially recorded at estimated fair value. We amortize capitalized software using the straight-line method primarily over estimated lives ranging up to seven years. We annually review the estimated lives and methods used to amortize our other intangible assets. The amount of future amortization expense may differ materially from current amounts, depending on the results of our annual reviews.

Our goodwill was derived from Lumen's acquisition of us where the purchase price exceeded the fair value of the net assets acquired.

We are required to assess our goodwill for impairment annually, or more frequently if an event occurs or circumstances change that indicates it is more likely than not the fair values of any of our reporting units were less than their carrying values. In assessing goodwill for impairment, we may first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value.

Our annual impairment assessment date for goodwill was October 31, at which date we compared our estimated fair value of equity of our reporting unit to the carrying value of equity. If the estimated fair value was greater than the carrying value, we concluded no impairment exists. If the estimated fair value was less than the carrying value, we recorded a non-cash impairment charge equal to the excess amount. Depending on the facts and circumstances, we typically estimated the fair value by considering either or both of (i) a discounted cash flow method, which was based on the present value of projected cash flows over a discrete projection period and a terminal value, which was based on the expected normalized cash flows following the discrete projection period, and (ii) a market approach, which included the use of multiples of publicly-traded companies whose services were comparable to ours. With respect to our analysis using the discounted cash flow method, the timing and amount of projected cash flows under these forecasts required estimates developed from our long-range plan, which is informed by wireline industry trends, the competitive landscape, product lifecycles, operational initiatives, capital allocation plans and other company-specific and external factors that influence our business. These projected cash flows considered recent historical results and are consistent with the Company's short-term financial forecasts and long-term business strategies. Due to inherent uncertainties, actual cash flows could vary significantly from our projected cash flows. Our determination of the discount rate was based on a weighted average cost of capital approach, which used a market participant’s cost of equity and after-tax cost of debt and reflects certain risks inherent in the projected cash flows. With respect to our analysis using the market approach, the fair value was estimated based upon a market multiple applied to revenue and earnings before interest, taxes, depreciation and amortization ("EBITDA"), adjusted for an appropriate control premium based on recent market transactions. The fair value of our reporting unit was estimated under the market approach, using these revenue and EBITDA market multiples weighted depending on the characteristics of our reporting unit. We performed sensitivity analyses that considered a range of discount rates and a range of EBITDA market multiples and we believe the estimates, judgments, assumptions and allocation methods used by us were reasonable. Nonetheless, changes in any of them can significantly affect whether we must incur impairment charges, as well as the size of such charges.

For additional information on our goodwill balances and results of our impairment analyses, see Note 2—Goodwill and Other Intangible Assets for additional information.

Affiliate Transactions

We recognize intercompany charges for the amounts billed to us by our affiliates and we recognize intercompany revenue for services we bill to our affiliates.

Because of the significance of the services we provide to our affiliates and our other affiliate transactions, the results of operations, financial position and cash flows presented herein are not necessarily indicative of the results of operations, financial position and cash flows we would have achieved had we operated as a stand-alone entity during the periods presented. As it relates to telecommunications services provided to our affiliates, we expect a significant reduction to affiliate revenue for the fiscal year ended December 31, 2025. This is primarily due to the repricing of certain services to align with lower market rates including certain transport services, along with the termination of certain affiliate circuits that are no longer required to support services provided to our external customers. See Note 13—Affiliate Transactions for additional information.

Income Taxes

We are included in the consolidated federal income tax return of Lumen Technologies. Lumen Technologies treats our consolidated results as if we were a separate taxpayer. We are required to pay our tax liabilities to Lumen Technologies based upon our separate return taxable income. We are also included in the combined state tax returns filed by Lumen Technologies.

Our provision for income taxes includes amounts for tax consequences deferred to future periods. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to tax credit carryforwards and differences between the financial statement carrying value of assets and liabilities and the tax bases of those assets and liabilities. Deferred taxes are computed using enacted tax rates expected to apply in the year in which the differences are expected to affect taxable income. The effect on deferred income tax assets and liabilities of a change in tax rate is recognized in earnings in the period that includes the enactment date.

The measurement of deferred taxes often involves the exercise of considerable judgment related to the realization of tax basis. Our deferred tax assets and liabilities reflect our assessment that tax positions taken in filed tax returns and the resulting tax basis are more likely than not to be sustained if they are audited by taxing authorities. Assessing tax rates that we expect to apply and determining the years when the temporary differences are expected to affect taxable income requires judgment about the future apportionment of our income among the states in which we operate. Any changes in our practices or judgments involved in the measurement of deferred tax assets and liabilities could materially impact our financial condition or results of operations. See Note 12—Income Taxes for additional information.
