Background and Summary of Significant Accounting Policies

General

We are an integrated communications company engaged primarily in providing a broad array of communications services to our business and residential customers. Our specific products and services are detailed under the heading "Operations - Products and Services" in Item 1 of Part I of this report.

We generate the majority of our total consolidated operating revenue from services provided in the 14-state region of Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. We refer to this region as our local service area.

On April 1, 2011, our indirect parent QCII became a wholly-owned subsidiary of CenturyLink, Inc. in a tax-free, stock-for-stock transaction.

Basis of Presentation

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (referred to herein as affiliates) have not been eliminated.

We reclassified certain prior period amounts to conform to the current period presentation. See Note 13—Products and Services Revenue for additional information. These changes had no impact on total operating revenue, total operating expenses or net income for any period presented.

Summary of Significant Accounting Policies

Use of Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions we make when accounting for specific items and matters, including, but not limited to, revenue recognition, revenue reserves, network access costs, network access cost dispute reserves, investments, long-term contracts, customer retention patterns, allowance for doubtful accounts, depreciation, amortization, asset valuations, rates used for affiliate cost allocations, internal labor capitalization rates, recoverability of assets (including deferred tax assets), impairment assessments, taxes, certain liabilities and other provisions and contingencies, are reasonable, based on information available at the time they are made. These estimates, judgments and assumptions can materially affect the reported amounts of assets, liabilities and components of stockholder's equity as of the dates of the consolidated balance sheets, as well as the reported amounts of revenue, expenses and components of cash flows during the periods presented in our other consolidated financial statements. We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 12—Income Taxes and Note 16—Commitments, Contingencies and Other Items for additional information.

For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.

For matters related to income taxes, if we determine that the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. No portion of an uncertain tax position will be recognized if the position has less than a 50% likelihood of being sustained. Interest is recognized on the amount of unrecognized benefit from uncertain tax positions.

For all of these and other matters, actual results could differ materially from our estimates.

Revenue Recognition

We earn most of our consolidated revenue from contracts with customers, primarily through the provision of communications and other services. Revenue from contracts with customers is accounted for under Accounting Standards Codification ("ASC") 606. We also earn revenue from leasing arrangements (primarily fiber capacity agreements) and governmental subsidy payments, neither of which are accounted for under ASC 606.

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to receive in exchange for those goods or services. Revenue is recognized based on the following five-step model:

Identification of the contract with a customer;

Identification of the performance obligations in the contract;

Determination of the transaction price;

Allocation of the transaction price to the performance obligations in the contract; and

Recognition of revenue when, or as, we satisfy a performance obligation.

We provide an array of communications services to business and residential customers, including local voice, VPN, Ethernet, data, broadband, private line (including special access), network access, transport, voice, information technology, video and other ancillary services. We provide these services to a wide range of businesses, including global/international, enterprise, wholesale, government, small and medium business customers. Certain contracts also include the sale of equipment, which is not significant to our business.

We recognize revenue for services when we provide the applicable service or when control is transferred. Recognition of certain payments received in advance of services being provided is deferred. These advance payments include certain activation and certain installation charges. If the activation and installation charges are not separate performance obligations, we recognize them as revenue over the actual or expected contract term using historical experience, which ranges from one year to five years depending on the service. In most cases, termination fees or other fees on existing contracts that are negotiated in conjunction with new contracts are deferred and recognized over the new contract term.

For access services, we generally bill fixed monthly charges one month in advance to customers and recognize revenue as service is provided over the contract term in alignment with the customer's receipt of service. For usage and other ancillary services, we generally bill in arrears and recognize revenue as usage or delivery occurs.

In certain cases, customers may be permitted to modify their contracts. We evaluate the change in scope or price to identify whether the modification should be treated as a separate contract, whether the modification is a termination of the existing contract and creation of a new contract, or if it is a change to the existing contract.

Customer contracts are evaluated to determine whether the performance obligations are separable. If the performance obligations are deemed separable and separate earnings processes exist, the total transaction price that we expect to receive with the customer is allocated to each performance obligation based on its relative standalone selling price. The revenue associated with each performance obligation is then recognized as earned.

We periodically sell optical capacity on our network. These transactions are structured as indefeasible rights of use, commonly referred to as IRUs, which are the exclusive right to use a specified amount of capacity or fiber for a specified term, typically 10 to 20 years. In most cases, we account for the cash consideration received on transfers of optical capacity as ASC 606 revenue which is adjusted for the time value of money and is recognized ratably over the term of the agreement. Cash consideration received on transfers of dark fiber is accounted for as non-ASC 606 lease revenue, which we also recognize ratably over the term of the agreement. We do not recognize revenue on any contemporaneous exchanges of our optical capacity assets for other non-owned optical capacity assets.

In connection with offering products and services provided to the end user by third-party vendors, we review the relationship between us, the vendor and the end user to assess whether revenue should be reported on a gross or net basis. In assessing whether revenue should be reported on a gross or net basis, we consider whether we act as a principal in the transaction and control the goods and services used to fulfill the performance obligations associated with the transaction.

We have service level commitments pursuant to contracts with certain of our customers. To the extent that such service levels are not achieved or are otherwise disputed due to performance or service issues or other service interruptions or conditions, we will estimate the amount of credits to be issued and record a corresponding reduction to revenue in the period that the service level commitment was not met.

Customer payments are made based on billing schedules included in our customer contracts, which is typically on a monthly basis.

We defer (i.e. capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 30 months for consumer and up to 49 months for business. These deferred costs are monitored every period to reflect any significant change in assumptions.

See Note 3—Revenue Recognition for additional information.

Affiliate Transactions

We provide to our affiliates telecommunications services that we also provide to external customers. In addition, we provide to our affiliates computer system development and support services. Services provided by us to our affiliates are recognized as operating revenue-affiliates in our consolidated statements of operations. We also purchase services from our affiliates including telecommunications services, marketing and employee-related support services. Services provided to us from our affiliates are recognized as operating expenses-affiliates on our consolidated statements of operations. Because of the significance of the services we provide to our affiliates and our affiliates provide to us, 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.

We recognize intercompany charges at the amounts billed to us by our affiliates and we recognize intercompany revenue for services we bill to our affiliates. Regulatory rules require certain revenue and expenses to be recorded at market price or fully distributed cost. Our compliance with regulations is subject to review by regulators. Adjustments to intercompany charges that result from these reviews are recorded in the period they become known.

CenturyLink has cash management arrangements between certain of its subsidiaries that include lines of credit, affiliate obligations, capital contributions and dividends. As part of these cash management arrangements, an affiliate provides lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is transferred on a daily basis for centralized management by CenturyLink and most affiliate transactions are deemed to be settled at the time the transactions are recorded in our accounting records, with the resulting net balance at the end of each period reflected as advances to affiliates on the accompanying consolidated balance sheets. From time to time we declare and pay dividends to our parent, QSC, which are settled through the advances to affiliates, which has the net effect of reducing the amount of these advances. Dividends declared are reflected on our consolidated statements of stockholder's equity and the consolidated statements of cash flows reflects the changes in advances to affiliates as investing activities and changes in advances from affiliates as financing activities. Interest is assessed on the advances to/from affiliates on either the three-month U.S T-bill rate (for advances to affiliates) or CenturyLink’s weighted average borrowing rate (for advances from affiliates).

The affiliate obligations, net in current and noncurrent liabilities on our consolidated balance sheets primarily represents the cumulative allocation of expense, net of payments, associated with QCII’s pension plans and post-retirement benefits plans prior to the plan mergers. In 2015, we agreed to a plan to settle the outstanding affiliate obligations, net balance with QCII over a 30 year term. Under the plan, payments are scheduled to be made on a monthly basis. For the years ended December 31, 2019 and 2018, we made settlement payments of $76 million and $87 million, respectively, to QCII in accordance with the plan. Changes in the affiliate obligations, net are reflected in operating activities on our consolidated statements of cash flows.

In the normal course of business, we transfer assets to and from various affiliates through our parent, QSC, which are recorded through our equity. It is our policy to record asset transfers based on carrying values.

USF Surcharges, Gross Receipts Taxes and Other Surcharges

In determining whether to include in our revenue and expenses the taxes and surcharges collected from customers and remitted to government authorities, including USF surcharges, sales, use, value added and some excise taxes, we assess, among other things, whether we are the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where we do business. In jurisdictions where we determine that we are the principal taxpayer, we record the surcharges on a gross basis and include them in our revenue and costs of services and products. In jurisdictions where we determine that we are merely a collection agent for the government authority, we record the taxes on a net basis and do not include them in our revenue and costs of services and products.

Advertising Costs

Costs related to advertising are expensed as incurred and included in selling, general and administrative expenses in our consolidated statements of operations. Our advertising expense was $28 million, $58 million and $139 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Legal Costs

In the normal course of our business, we incur costs to hire and retain external legal counsel to advise us on regulatory, litigation and other matters. We expense these costs as the related services are received.

Income Taxes

Our results are included in the CenturyLink consolidated federal income tax return and certain combined state income tax returns. CenturyLink allocates income tax expense to us based upon a separate return allocation method which results in income tax expense that approximates the expense that would result if we were a stand-alone entity. Our reported deferred tax assets and liabilities, as discussed below and in Note 12—Income Taxes, are primarily determined as a result of the application of the separate return allocation method and therefore the settlement of these amounts is dependent upon our parent, CenturyLink, rather than tax authorities. Our current expectation is that the vast majority of deferred tax assets and liabilities will be settled through our general intercompany obligation based upon the current CenturyLink policy. CenturyLink has the right to change their policy regarding settlement of these assets and liabilities at any time.

The provision for income taxes consists of an amount for taxes currently payable, an amount for tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to differences between the financial statement carrying value of assets and liabilities and the tax basis 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.

We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain all or a portion of the valuation allowance on our deferred tax assets. See Note 12—Income Taxes for additional information.

Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments that are readily convertible into cash and are not subject to significant risk from fluctuations in interest rates. As a result, the value at which cash and cash equivalents are reported in our consolidated financial statements approximates their fair value. Our cash collections are transferred to CenturyLink on a daily basis and our ultimate parent funds our cash disbursement needs. The net cash transferred to CenturyLink has been reflected as advances to affiliates in our consolidated balance sheets.

Book overdrafts occur when checks have been issued but have not been presented to our controlled disbursement bank accounts for payment. Disbursement bank accounts allow us to delay funding of issued checks until the checks are presented for payment. Until the issued checks are presented for payment, the book overdrafts are included in accounts payable on our consolidated balance sheet. This activity is included in the operating activities section in our consolidated statements of cash flows.

Restricted Cash and Securities

Restricted cash and securities consists primarily of cash and investments that serve to collateralize certain performance and operating obligations. Restricted cash and securities are recorded as current and non-current assets in the consolidated balance sheets depending on the duration of the restriction and the purpose for which the restriction exists. Restricted securities are stated at cost which approximates fair value as of December 31, 2019 and 2018.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recognized based upon the amount due from customers for the services provided or at cost for purchased and other receivables less an allowance for doubtful accounts. The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. We generally consider our accounts past due if they are outstanding over 30 days. Our collection process varies by the customer segment, amount of the receivable, and our evaluation of the customer's credit risk. Our past due accounts are written off against our allowance for doubtful accounts when collection is considered to be not probable. Any recoveries of accounts previously written off are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable, net of the allowance for doubtful accounts, approximates fair value.

Property, Plant and Equipment

As a result of our indirect acquisition by CenturyLink, property, plant and equipment acquired at the time of acquisition was recorded based on its estimated fair value as of the acquisition date. Subsequently purchased and constructed property, plant and equipment are recorded at cost. Property, plant and equipment is depreciated primarily using the straight-line group method. Under the straight-line group method, assets dedicated to providing telecommunications services (which comprise the majority of our property, plant and equipment) that have similar physical characteristics, use and expected useful lives are pooled for purposes of depreciation and tracking. The equal life group procedure is used to establish each pool's average remaining useful life. Generally, under the straight-line group method, when an asset is sold or retired in the course of normal business activities, the cost is deducted from property, plant and equipment and charged to accumulated depreciation without recognition of a gain or loss. A gain or loss is recognized in our consolidated statements of operations only if a disposal is unusual. Leasehold improvements are amortized over the shorter of the useful lives of the assets or the expected lease term. Expenditures for maintenance and repairs are expensed as incurred. Interest is capitalized during the construction phase of network and other internal-use capital projects. Employee-related costs for construction of network and other internal use assets are also capitalized during the construction phase. Property, plant and equipment supplies used internally are carried at average cost, except for significant individual items for which cost is based on specific identification.

We perform annual internal reviews to evaluate the reasonableness of the depreciable lives for our property, plant and equipment. Our reviews utilize models that take into account actual usage, physical wear and tear, replacement history, assumptions about technology evolution and, in certain instances, actuarially determined probabilities to estimate the remaining useful life of our asset base. Our remaining useful life assessments assess the possible loss in service value of assets that may precede the physical retirement. Assets shared among many customers may lose service value as those customers reduce their use of the network. However, the asset is not retired until all customers no longer utilize the asset and we determine there is no alternative use for the asset.

We review long-lived tangible assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. For assessment purposes, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, absent a material change in operations. An impairment loss is recognized only if the carrying amount of the asset group is not recoverable and exceeds its estimated fair value. Recoverability of the asset group to be held and used is assessed by comparing the carrying amount of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. If the asset group's carrying value is not recoverable, we recognize an impairment charge for the amount by which the carrying amount of the asset group exceeds its estimated fair value.

Goodwill, Customer Relationships and Other Intangible Assets

Intangible assets arising from business combinations, such as goodwill, customer relationships and capitalized software are initially recorded at estimated fair value. We amortize customer relationships primarily over an estimated life of ten years, using either the sum-of-the-years-digits or the straight-line methods, depending on the type of customer. We amortize capitalized software using the straight-line method over estimated lives ranging up to seven years. Other intangible assets not arising from business combinations are initially recorded at cost.

Internally used software, whether purchased or developed by us, is capitalized and amortized using the straight-line method over its estimated useful life. We have capitalized certain costs associated with software such as costs of employees devoting time to the projects and external direct costs for materials and services. Costs associated with software to be used for internal purposes are expensed until the point at which the project has reached the development stage. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance, data conversion and training costs are expensed in the period in which they are incurred. We review the remaining economic lives of our capitalized software annually. Capitalized software is included in other intangible assets, net, in our consolidated balance sheets.

We are required to assess goodwill for impairment at least annually, or more frequently, if an event occurs or circumstances change that would indicate an impairment may have occurred. We are required to write-down the value of goodwill in periods in which the carrying amount of the reporting unit equity exceeds the estimated fair value of the equity of the reporting unit limited to the goodwill balance. The impairment assessment is performed at the reporting unit level. We have determined that our operations consist of one reporting unit, consistent with our determination that our business consists of one operating segment. See Note 2—Goodwill, Customer Relationships and Other Intangible Assets for additional information.

Pension and Post-Retirement Benefits

A substantial portion of our active and retired employees participate in the CenturyLink Combined Pension Plan. On December 31, 2014, the QCII pension plan and a pension plan of an affiliate were merged into the CenturyLink Retirement Plan. The CenturyLink Retirement Plan was renamed the CenturyLink Combined Pension Plan. Prior to the pension plan merger, the above-noted employees participated in the QCII pension plan. In addition, certain of our employees participate in CenturyLink's post-retirement health care and life insurance benefit plans. CenturyLink allocates service costs relating to pension and post-retirement health care and life insurance benefits to us and its other affiliates. The amounts contributed by us through CenturyLink are not segregated or restricted to pay amounts due to our employees and may be used to provide benefits to other employees of CenturyLink. The allocation of the service costs to us is based upon our employees who are currently earning benefits under the plans.

For further information on qualified pension, post-retirement and other post-employment benefit plans, see CenturyLink's annual report on Form 10-K for the year ended December 31, 2019.

Recently Adopted Accounting Pronouncements

During 2019, we adopted Accounting Standards Update ("ASU") 2016-02, "Leases (ASC 842"). In 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” and ASU 2017-04, "Simplifying the Test for Goodwill Impairment".

Each of these is described further below.

Leases

We adopted Accounting Standards Update ("ASU") 2016-02, "Leases (ASC 842)", as of January 1, 2019, using the non-comparative transition option pursuant to ASU 2018-11. Therefore, we have not restated comparative period financial information for the effects of ASC 842, and we will not make the new required lease disclosures for comparative periods beginning before January 1, 2019. Instead, we recognized ASC 842's cumulative effect transition adjustment (discussed below) as of January 1, 2019. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things (i) allowed us to carry forward the historical lease classification; (ii) did not require us to reassess whether any expired or existing contracts are or contain leases under the new definition of a lease; and (iii) did not require us to reassess whether previously capitalized initial direct costs for any existing leases would qualify for capitalization under ASC 842. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. We did not elect the hindsight practical expedient regarding the likelihood of exercising a lessee purchase option or assessing any impairment of right-of-use assets for existing leases.
On March 5, 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-01, "Leases (ASC 842): Codification Improvements", effective for public companies for fiscal years beginning after December 15, 2019. The new ASU aligns the guidance in ASC 842 for determining fair value of the underlying asset by lessors that are not manufacturers or dealers, with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value (in ASC 820, "Fair Value Measurement") should be applied. More importantly, the ASU also exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. Early adoption permits public companies to adopt concurrent with the transition to ASC 842 on leases. We adopted ASU 2019-01 as of January 1, 2019.

Adoption of the new standards resulted in the recording of operating lease assets and operating lease liabilities of approximately $126 million and $133 million, respectively, as of January 1, 2019. The standards did not materially impact our consolidated net earnings and had no material impact on cash flows. Our financial position for reporting periods beginning on or after January 1, 2019 is presented under the new guidance, as discussed above, while prior period amounts are not adjusted and continue to be reported in accordance with previous guidance.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") ASU 2014-09 which replaces virtually all existing generally accepted accounting principles on revenue recognition with a principles-based approach for determining revenue recognition using a new five step model. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also includes new accounting principles related to the deferral and amortization of contract acquisition and fulfillment costs.

We adopted the new revenue recognition standard on January 1, 2018 using the modified retrospective transition method applying the rules to all open contracts existing as of January 1, 2018. During the year ended December 31, 2018, we recorded a cumulative catch-up adjustment that increased our retained earnings by $141 million, net of $49 million of income taxes.

See Note 3—Revenue Recognition for additional information.

Income Taxes

In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” ("ASU 2016-16"). ASU 2016-16 eliminates the current prohibition on the recognition of the income tax effects on the transfer of assets among our subsidiaries. After adoption of ASU 2016-16, the income tax effects associated with these asset transfers, except for the transfer of inventory, will be recognized in the period the asset is transferred versus the current deferral and recognition upon either the sale of the asset to a third party or over the remaining useful life of the asset. We adopted ASU 2016-16 on January 1, 2018. The adoption of ASU 2016-16 did not have a material impact to our consolidated financial statements.

Goodwill Impairment

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 simplifies the impairment testing for goodwill by changing the measurement for goodwill impairment. Under current rules, we are required to compute the fair value of goodwill to measure the impairment amount if the carrying value of a reporting unit exceeds its fair value. Under ASU 2017-04, the goodwill impairment charge will equal the excess of the reporting unit carrying value above fair value, limited to the amount of goodwill assigned to the reporting unit.

We elected to early adopt the provisions of ASU 2017-04 as of October 1, 2018.

Recently Issued Accounting Pronouncements

Financial Instruments

In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments". The primary impact of ASU 2016-13 for us is a change in the model for the recognition of credit losses related to our financial instruments from an incurred loss model, which recognized credit losses only if it was probable that a loss had been incurred, to an expected loss model, which requires our management team to estimate the total credit losses expected on the portfolio of financial instruments.

We are in the process of implementing the model for the recognition of credit losses related to our financial instruments, new processes and internal controls to assist us in the application of the new standard. The cumulative effect of initially applying the new standard on January 1, 2020 is not material.

We annually review the estimated lives and methods used to amortize our other intangible assets. The actual amounts of amortization expense may differ materially from our estimates, depending on the results of our annual reviews.

Substantially, all of our goodwill was derived from CenturyLink's acquisition of us where the purchase price exceeded the fair value of the net assets acquired.

We assess our goodwill for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. We are required to write-down the value of goodwill in periods in which the carrying value of equity exceeds the estimated fair value of equity, limited to the amount of goodwill. Our annual impairment assessment date for goodwill is October 31, at which date we assessed goodwill at our reporting unit. In reviewing the criteria for reporting units, we have determined that we are one reporting unit.

At October 31, 2019, we estimated the fair value of our equity by considering both a market approach and a discounted cash flow method. The market approach method includes the use of comparable multiples of publicly traded companies whose services are comparable to ours. The discounted cash flow method is based on the present value of projected cash flows and a terminal value, which represents the expected normalized cash flows of the reporting unit beyond the cash flows from the discrete projection period. Based on our assessment performed with respect to our reporting unit as described above, we concluded that our goodwill was not impaired as of that date.

The decline in CenturyLink’s stock price triggered impairment testing in the first quarter of 2019. Consequently, we evaluated our goodwill as of March 31, 2019. Because CenturyLink's low stock price was a trigger for impairment testing, we estimated the fair value of our operations using only the market approach in the quarter ended March 31, 2019. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry. As of March 31, 2019, based on our assessments performed as described above, we concluded that our goodwill was not impaired as of that date.

The market multiples approach that we used in the quarter ended March 31, 2019 incorporated significant estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain cost synergies. In developing the market multiple, we also considered observed trends of our industry participants. Our assessment included many qualitative factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairments. 

As of October 31, 2018, based on our assessments performed, we concluded that our goodwill was not impaired as of that date.

Gross customer receivables of $462 million and $554 million, net of allowance for doubtful accounts of $32 million and $36 million, at December 31, 2019 and December 31, 2018, respectively.
Contract liabilities are consideration we have received from our customers or billed in advance of providing goods and services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation and maintenance charges that are deferred and recognized over the actual or expected contract term, which ranges from one to five years depending on the service. Contract liabilities are included within deferred revenue in our consolidated balance sheet. During the years ended December 31, 2019 and December 31, 2018, we recognized $273 million and $42 million, respectively, of revenue that was included in contract liabilities as of January 1, 2019 and January 1, 2018, respectively.

Performance Obligations

As of December 31, 2019, our estimated revenue expected to be recognized in the future related to performance obligations associated with customer contracts that are unsatisfied (or partially satisfied) is approximately $162 million. We expect to recognize approximately 99% of this revenue through 2022, with the balance recognized thereafter.

We do not disclose the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed (for example, uncommitted usage or non-recurring charges associated with professional or technical services to be completed), or contracts that are classified as leasing arrangements that are not subject to ASC 606.

Acquisition costs include commissions paid to employees as a result of obtaining contracts. Fulfillment costs include third party and internal costs associated with the provision, installation and activation of telecommunications services to customers, including labor and materials consumed for these activities.

Deferred acquisition and fulfillment costs are amortized based on the transfer of services on a straight-line basis over the average contract life of 30 months for consumer customers and up to 49 months for business customers and amortized fulfillment costs are included in cost of services and products and amortized acquisition costs are included in selling, general and administrative expenses in our consolidated statements of operations. The amount of acquisition costs included in these deferred costs that are anticipated to be amortized in the next twelve months are included in other current assets on our consolidated balance sheets. The amount of deferred costs expected to be amortized beyond the next twelve months is included in other non-current assets on our consolidated balance sheets. Deferred acquisition and fulfillment costs are assessed for impairment on an annual basis.

Our financial position for reporting periods beginning on or after January 1, 2019 is presented under the new accounting guidance, while prior periods amounts are not adjusted and continue to be reported in accordance with previous guidance, as discussed in Note 1—Background and Summary of Significant Accounting Policies.

We primarily lease various office facilities, switching and colocation facilities, equipment and dark fiber. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.
We determine if an arrangement is a lease at inception and whether that lease meets the classification criteria of a finance or operating lease. Lease-related assets, or right-of-use assets, are recognized at the lease commencement date at amounts equal to the respective lease liabilities. Lease-related liabilities are recognized at the present value of the remaining contractual fixed lease payments, discounted using our incremental borrowing rates. As part of the present value calculation for the lease liabilities, we use an incremental borrowing rate as the rates implicit in the leases are not readily determinable. The incremental borrowing rates used for lease accounting are based on our unsecured rates, adjusted to approximate the rates at which we could borrow on a collateralized basis over a term similar to the recognized lease term. We apply the incremental borrowing rates to lease components using a portfolio approach based upon the length of the lease term and the reporting entity in which the lease resides. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.

Some of our lease arrangements contain lease components (including fixed payments, such as, rent, real estate taxes and insurance costs) and non-lease components (including common-area maintenance costs). We generally account for each component separately based on the estimated standalone price of each component. For colocation leases, we account for the lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain to be exercised. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

We lease various equipment, office facilities, retail outlets, switching facilities and other network sites. These leases, with few exceptions, provide for renewal options and escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The lease term for most leases includes the initial non-cancelable term plus any term under renewal options that are reasonably assured. For the years ended December 31, 2019, 2018 and 2017, our gross rental expense was $53 million, $64 million and $70 million, respectively. We also received sublease rental income for the years ended December 31, 2019, 2018 and 2017 of $10 million, $2 million and $2 million, respectively.

We primarily lease various office facilities, switching and colocation facilities, equipment and dark fiber. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term.
We determine if an arrangement is a lease at inception and whether that lease meets the classification criteria of a finance or operating lease. Lease-related assets, or right-of-use assets, are recognized at the lease commencement date at amounts equal to the respective lease liabilities. Lease-related liabilities are recognized at the present value of the remaining contractual fixed lease payments, discounted using our incremental borrowing rates. As part of the present value calculation for the lease liabilities, we use an incremental borrowing rate as the rates implicit in the leases are not readily determinable. The incremental borrowing rates used for lease accounting are based on our unsecured rates, adjusted to approximate the rates at which we could borrow on a collateralized basis over a term similar to the recognized lease term. We apply the incremental borrowing rates to lease components using a portfolio approach based upon the length of the lease term and the reporting entity in which the lease resides. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are expensed as incurred.

Some of our lease arrangements contain lease components (including fixed payments, such as, rent, real estate taxes and insurance costs) and non-lease components (including common-area maintenance costs). We generally account for each component separately based on the estimated standalone price of each component. For colocation leases, we account for the lease and non-lease components as a single lease component.

Many of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain to be exercised. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

We lease various equipment, office facilities, retail outlets, switching facilities and other network sites. These leases, with few exceptions, provide for renewal options and escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. The lease term for most leases includes the initial non-cancelable term plus any term under renewal options that are reasonably assured. For the years ended December 31, 2019, 2018 and 2017, our gross rental expense was $53 million, $64 million and $70 million, respectively. We also received sublease rental income for the years ended December 31, 2019, 2018 and 2017 of $10 million, $2 million and $2 million, respectively.

Operating Lease Income

Qwest leases various data transmission capacity, office facilities, switching facilities and other network sites to third parties under operating leases. Lease and sublease income are included in operating revenue in the consolidated statements of operations.

For the years ended December 31, 2019, 2018 and 2017, our gross rental income was $320 million, $522 million and $555 million, respectively which represents 4%, 6% and 6%, respectively, of our operating revenue for the years ended December 31, 2019, 2018 and 2017.

(1) Qwest Corporation's Term Loan had an interest rate of 3.800% as of December 31, 2019 and 4.530% as of December 31, 2018.
Repayment

During 2019, we did not repay any of our long-term debt.

During 2018, we retired approximately $1.3 billion in debt securities including approximately $164 million of Qwest Corporation 7.5% Notes due 2051, $925 million of Qwest Corporation 7.0% Notes due 2052, and $250 million of Qwest Corporation 7.25% Notes due 2035 and we recognized a loss of $34 million.

Term Loan

In 2015, Qwest Corporation entered into a term loan in the amount of $100 million with CoBank, ACB. The outstanding unpaid principal amount of this term loan plus any accrued and unpaid interest is due on February 20, 2025. Interest is paid at least quarterly based upon either the applicable London Interbank Offered Rate (“LIBOR”) or the base rate (as defined in the credit agreement) plus an applicable margin between 1.50% to 2.50% per annum for LIBOR loans and 0.50% to 1.50% per annum for base rate loans depending on Qwest Corporation's then current senior unsecured long-term debt rating. At both December 31, 2019 and 2018, the outstanding principal balance on this term loan was $100 million.

Aggregate Maturities of Long-Term Debt

Revolving Promissory Note

On September 30, 2017, Qwest Corporation entered into an amended and restated revolving promissory note in the amount of $965 million with an affiliate of our ultimate parent company, CenturyLink, Inc. This note replaced and amended the original $1.0 billion revolving promissory note Qwest Corporation entered into on April 18, 2012 with the same affiliate. The outstanding principal balance of this new revolving promissory note and the accrued interest thereon shall be due and payable on demand, but if no demand is made, then on June 30, 2022. Interest is accrued on the outstanding balance during an interest period using a weighted average per annum interest rate on the consolidated outstanding debt of CenturyLink and its subsidiaries. As of December 31, 2019, the amended and restated revolving promissory note had an outstanding balance of $1.069 billion and bore interest at a weighted-average interest rate of 5.843%. As of December 31, 2019 and 2018, the amended and restated revolving promissory note is reflected on our consolidated balance sheet as a current liability under “Note payable-affiliate”. In accordance with the terms of the amended and restated revolving promissory note, interest shall be assessed on June 30th and December 31st (an "Interest Period"). Any assessed interest for an Interest Period that remains unpaid on the last day of the subsequent Interest Period is capitalized on such date and begins accruing interest. Through December 31, 2019, $104 million of such interest has been capitalized. As of December 31, 2019 and 2018, $31 million and $30 million of accrued interest is reflected in other current liabilities on our consolidated balance sheet.

Covenants

Our senior notes were issued under indentures dated April 15, 1990 and October 15, 1999. These indentures contain certain covenants including, but not limited to: (i) a prohibition on certain liens on our assets; and (ii) a limitation on mergers or sales of all, or substantially all, of our assets, which limitation requires that a successor assume the obligation with regard to these notes. These indentures do not contain any cross-default provisions. These indentures do not contain any financial covenants or restrictions on our ability to issue new securities thereunder. Except for a limited number of series of our notes, we generally can redeem our senior notes, at our option, typically at a fixed price.

Under the Qwest Corporation term loan, Qwest Corporation must maintain a debt to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in CenturyLink's Credit Facility) ratio of not more than 2.85:1.0, as of the last day of each fiscal quarter for the four quarters then ended. The term loan also contains a negative pledge covenant, which generally requires us to secure equally and ratably any advances under the term loan if we pledge assets or permit liens on our property for the benefit of other debtholders. The term loan also has a cross payment default and cross acceleration provisions. When present, these provisions could have a wider impact on liquidity than might otherwise arise from a default or acceleration of a single debt instrument. Our debt to EBITDA ratio could be adversely impacted by a wide variety of events, including unforeseen contingencies, many of which are beyond our control. This could reduce our financing flexibility due to potential restrictions on incurring additional debt under certain provisions of our debt agreements or, in certain circumstances, could result in a default under certain provisions of such agreements.

None of our long-term debt is secured or guaranteed by other companies.

Compliance

At December 31, 2019 and 2018, we believe we were in compliance with the financial covenants contained in our debt agreements in all material respects.

Subsequent Event

On January 15, 2020, Qwest Corporation fully redeemed all $850 million aggregate principal amount of its outstanding 6.875% senior notes due 2033 and all $250 million aggregate principal amount of its outstanding 7.125% senior notes due 2043.

Pension and Post-Retirement Benefits

QCII's post-retirement benefit plans were merged into CenturyLink's post-retirement benefit plans on January 1, 2012 and on December 31, 2014, QCII's qualified pension plan and a pension plan of an affiliate were merged into the CenturyLink Retirement Plan, which was renamed the CenturyLink Combined Pension Plan. Based on current laws and circumstances, (i) CenturyLink was not required to make a cash contribution to the CenturyLink Combined Pension Plan in 2019 and (ii) CenturyLink does not expect it will be required to make a contribution in 2020. The amount of required contributions to the CenturyLink Combined Pension Plan in 2020 and beyond will depend on earnings on plan investments, prevailing discount rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. CenturyLink occasionally makes voluntary contributions in addition to required contributions, and CenturyLink made such voluntary cash contributions of $500 million to the CenturyLink Combined Pension Plan during 2018. CenturyLink did not make a voluntary contribution in 2019 and does not currently expect to make a voluntary contribution in 2020.

The unfunded status of CenturyLink's qualified pension plan for accounting purposes was $1.7 billion and $1.6 billion as of December 31, 2019 and 2018, respectively, which includes the merged QCII qualified pension plan. The unfunded status of CenturyLink's post-retirement benefit plans for accounting purposes was $3.0 billion for both periods as of December 31, 2019 and 2018.

CenturyLink allocates current service costs to subsidiaries relative to employees who are currently earning benefits under the pension and post-retirement benefit plans. The net cost allocated to us is paid on a monthly basis through CenturyLink’s intercompany cash management process.

The affiliate obligations, net in current and noncurrent liabilities on the consolidated balance sheets primarily represents the cumulative allocation of expense, net of payments, associated with QCII's pension plans and post-retirement benefits plans prior to the plan mergers. In 2015, we agreed to a plan to settle the outstanding pension and post-retirement affiliate obligations, net balance with QCII over a 30 year term. Under the plan, payments are scheduled to be made on a monthly basis. For the years ended December 31, 2019 and 2018, we made settlement payments in the aggregate of $76 million and $87 million, respectively, to QCII under the plan. Changes in the affiliate obligations, net are reflected in operating activities on our consolidated statements of cash flows.

We were allocated $40 million of pension service costs and $11 million of post-retirement service costs during the year ended December 31, 2019, which represented 70% of CenturyLink's total pension and post-retirement service costs for the year. The combined net pension and post-retirement service costs is included in cost of services and products and selling, general and administrative expenses on our consolidated statement of operations for the year ended December 31, 2019.

We were allocated $46 million of pension service costs and $11 million of post-retirement service costs during the year ended December 31, 2018, which represented 70% of CenturyLink's total pension and post-retirement service costs for the year. The combined net pension and post-retirement service costs is included in cost of services and products and selling, general and administrative expenses on our consolidated statement of operations for the year ended December 31, 2018.

We were allocated $44 million of pension service costs and $12 million of post-retirement service costs during the year ended December 31, 2017, which represented 70% of CenturyLink's total pension and post-retirement service costs for the year. The combined net pension and post-retirement service costs is included in cost of services and products and selling, general and administrative expenses on our consolidated statement of operations for the year ended December 31, 2017.

CenturyLink sponsors a noncontributory qualified defined benefit pension plan that covers certain of our eligible employees. The CenturyLink Combined Pension Plan also provides survivor and disability benefits to certain employees. In November 2009, and prior to the plan merger, the pension plan was amended to no longer provide pension benefit accruals for active non-represented employees after December 31, 2009. In addition, non-represented employees hired after January 1, 2009 are not eligible to participate in the plans. Active non-represented employees who participate in these plans retain their accrued pension benefit earned as of December 31, 2009 and certain participants will continue to earn interest credits on their benefit after December 31, 2009. Employees are eligible to receive their vested accrued benefit when they separate from CenturyLink. The plans also provided a death benefit for eligible beneficiaries of certain retirees; however, the plan was amended to eliminate this benefit effective March 1, 2010 for retirees who retired prior to January 1, 2004 and whose deaths occur after February 28, 2010 and eliminate the death benefit for eligible beneficiaries of certain retirees who retired after December 31, 2003.

CenturyLink maintains post-retirement benefit plans that provide health care and life insurance benefits for certain eligible retirees. The QCII post-retirement benefit plans were merged into CenturyLink's post-retirement benefit plans on January 1, 2012. The benefit obligation for the occupational health care and life insurance post-retirement plans is estimated based on the terms of benefit plans. In calculating this obligation, CenturyLink considers numerous assumptions, estimates and judgments, including but not limited to, discount rates, health care cost trend rates and plan amendments. During the third quarter of 2019, we renewed a collective bargaining agreement for three years which covers approximately 7,500 of our unionized employees. Effective with the renewal, there were no significant changes to the existing benefits for the approximately 7,500 active employees and eligible post-1990 retirees who are former represented employees. This agreement expires in April 2023.

The terms of the post-retirement health care and life insurance plans between CenturyLink and its eligible non-represented employees and its eligible post-1990 non-represented retirees are established by CenturyLink and are subject to change at its discretion. CenturyLink has a practice of sharing some of the cost of providing health care benefits with its non-represented employees and post-1990 non-represented retirees. The benefit obligation for the non-represented post-retirement health care benefits is based on the terms of the current written plan documents and is adjusted for anticipated continued cost sharing with non-represented employees and post-1990 non-represented retirees. However, CenturyLink's contribution under its post-1990 non-represented retirees' health care plan is capped at a specific dollar amount.

Medicare Prescription Drug, Improvement and Modernization Act of 2003

CenturyLink sponsors post-retirement health care plans with several benefit options that provide prescription drug benefits that CenturyLink deems actuarially equivalent to or exceeding Medicare Part D. CenturyLink recognizes the impact of the federal subsidy received under the Medicare Prescription Drug, Improvement and Modernization Act of 2003 in the calculation of its post-retirement benefit obligation and net periodic post-retirement benefit expense.

Other Benefit Plans

Health Care and Life Insurance

We provide health care and life insurance benefits to essentially all of our active employees. We are largely self-funded for the cost of the health care plan. Our health care benefit expense for current employees was $171 million, $211 million and $204 million for the years ended December 31, 2019, 2018 and 2017, respectively. Employees' group basic life insurance plans are fully insured and the premiums are paid by CenturyLink.

401(k) Plans

CenturyLink sponsors qualified defined contribution plans covering substantially all of our employees. Under these plans, employees may contribute a percentage of their annual compensation up to certain maximums, as defined by the plans and by the Internal Revenue Service ("IRS"). Currently, we match a percentage of our employees' contributions in cash. We recognized $46 million, $45 million and $42 million in expense related to these plans for the years ended December 31, 2019, 2018 and 2017, respectively.

Fair Value Disclosure

Our financial instruments consist of cash and cash equivalents, accounts receivable, advances to affiliates, accounts payable, note payable-affiliate and long-term debt, excluding finance lease and other obligations. Due to their short-term nature, the carrying amounts of our cash and cash equivalents, accounts receivable, advances to affiliates, accounts payable and note payable-affiliate approximate their fair values.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value and then we rank the estimated values based on the reliability of the inputs used following the fair value hierarchy set forth by the FASB. We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:
Input Level
 
Description of Input
 
 
 
Level 1
 
Observable inputs such as quoted market prices in active markets.
Level 2
 
Inputs other than quoted prices in active markets that are either directly or indirectly observable.
Level 3
 
Unobservable inputs in which little or no market data exists.


The following table presents the carrying amounts and estimated fair values of our long-term debt, excluding finance lease and other obligations, as well as the input levels used to determine the fair values:

Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act (the "Act") was signed into law. The Act reduces the U.S. corporate income tax rate from a maximum of 35% to 21% for all corporations, effective January 1, 2018, and makes certain changes to U.S. taxation of income earned by foreign subsidiaries, capital expenditures, interest expense and various other items.

As a result of the reduction in the U.S. corporate income tax rate from 35% to 21%, we re-measured our net deferred tax liabilities at December 31, 2017 and recognized a provisional tax benefit of $555 million in our consolidated statement of operations for the year ended December 31, 2017. Upon completion of our re-measurement during 2018 there was no material change to the provisional amount recorded in 2017.

The components of the income tax expense (benefit) from continuing operations are as follows:

The effective rate for the year ended December 31, 2018, was favorably impacted by a tax benefit of $83 million generated by filing tax accounting method changes that accelerated significant tax deductions. The effective tax rate for the year ended December 31, 2017 reflects the benefit of $555 million from the re-measurement of deferred taxes as noted above.

The tax effects of temporary differences that gave rise to significant portions of the deferred tax assets and deferred tax liabilities were as follows:

At December 31, 2019, we have established a valuation allowance of $8 million as it is not more likely than not that this amount of deferred tax assets will be realized.

With few exceptions, we are no longer subject to U.S. federal, state and local or non-U.S. income tax examinations by tax authorities for years before 2012. The Internal Revenue Service and state and local taxing authorities reserve the right to audit any period where net operating loss carryforwards are available.

A reconciliation of the change in our gross unrecognized tax benefits (excluding both interest and any related federal benefit) from January 1 to December 31 for 2019 and 2018 are as follows:

The total amount of unrecognized tax benefits (including interest and net of federal benefit) that, if recognized, would impact the effective income tax rate was $432 million and $435 million as of December 31, 2019 and 2018, respectively.

Our policy is to reflect interest expense associated with unrecognized tax benefits in income tax expense. We had accrued interest (presented before related tax benefits) of approximately $40 million and $21 million as of December 31, 2019 and 2018, respectively.

Based on our current assessment of various factors, including (i) the potential outcomes of these ongoing examinations, (ii) the expiration of statute of limitations for specific jurisdictions, (iii) the negotiated settlement of certain disputed issues, and (iv) the administrative practices of applicable taxing jurisdictions, it is reasonably possible that the related unrecognized tax benefits for uncertain tax positions previously taken may not change in the next 12 months. The actual amount of changes, if any, will depend on future developments and events, many of which are outside our control.

We paid $539 million and $907 million related to income taxes for the years ended December 31, 2019 and 2017, respectively and received $8 million from QSC related to income taxes in the year ended December 31, 2018.

Products and Services Revenues
Products and Services Revenue

We are an integrated communications company engaged primarily in providing an array of communications services, including local voice, broadband, private line (including business data services), Ethernet, network access, information technology and other ancillary services. We strive to maintain our customer relationships by, among other things, bundling our service offerings to provide our customers with a complete offering of integrated communications services.

We categorize our products, services and revenue among the following six categories:

IP and Data Services, which include primarily VPN data networks, Ethernet, IP and other ancillary services;

Transport and Infrastructure, which include broadband, private line (including business data services) and other ancillary services;

Voice and Collaboration, which includes primarily local voice, including wholesale voice, and other ancillary services;

IT and Managed Services, which include information technology services and managed services, which may be purchased in conjunction with our other network services;

Regulatory Revenue, which consist of Universal Service Fund ("USF") and Connect America Fund ("CAF") support payments and other operating revenue. We receive federal support payments from both federal and state USF programs and from the federal CAF program. These support payments are government subsidies designed to reimburse us for various costs related to certain telecommunications services including the costs of deploying, maintaining and operating voice and broadband infrastructure in high-cost rural areas where we are not able to fully recover our costs from our customers; and

Affiliate services, which are telecommunication services that we also provide to our external customers. In addition, we provide to our affiliates computer system development and support services, network support and technical services.

From time to time, we may change the categorization of our products and services.

Our operating revenue for our products and services consisted of the following categories for the years ended December 31, 2019, 2018 and 2017:

We do not have any single external customer that provides more than 10% of our total consolidated operating revenue. Substantially all of our consolidated revenue comes from customers located in the United States.

We recognize revenue in our consolidated statements of operations for certain USF surcharges and transaction taxes that we bill to our customers. Our consolidated statements of operations also reflect the offsetting expense for the amounts we remit to the government agencies. The USF surcharges are assigned to the products and services categories based on the underlying revenue. We also act as a collection agent for certain other USF and transaction taxes that we are required by government agencies to bill our customers, for which we do not record any revenue or expense because we only act as a pass-through agent.

The following table provides the amount of USF surcharges and transaction taxes:

Our operations are integrated into and reported as part of the consolidated segment data of CenturyLink. CenturyLink's chief operating decision maker ("CODM") is our CODM, but reviews our financial information on an aggregate basis only in connection with our quarterly and annual reports that we file with the Securities and Exchange Commission. Consequently, we do not provide our discrete financial information to the CODM on a regular basis. As such, we believe we have one reportable segment.

Affiliate Transactions

We provide to our affiliates, telecommunications services that we also provide to external customers. In addition, we provide to our affiliates, computer system development and support services and network support and technical services.

Below are details of the services we provide to our affiliates:

Telecommunications services. Data, broadband and voice services in support of our affiliates' service offerings;

Computer system development and support services. Information technology services primarily include the labor cost of developing, testing and implementing the system changes necessary to support order entry, provisioning, billing, network and financial systems, as well as the cost of improving, maintaining and operating our operations support systems and shared internal communications networks; and

Network support and technical services. Network support and technical services relate to forecasting demand volumes and developing plans around network utilization and optimization, developing and implementing plans for overall product development, provisioning and customer care.

We charge our affiliates for services that we also provide to external customers, while other services that we provide only to our affiliates are priced by applying a fully distributed cost ("FDC") methodology. FDC rates include salaries and wages, payroll taxes, employee related benefits, miscellaneous expenses, and charges for the use of our buildings, computing and software assets. Whenever possible, costs are directly assigned to our affiliates for the services they use. If costs cannot be directly assigned, they are allocated among all affiliates based upon cost causative measures; or if no cost causative measure is available, these costs are allocated based on a general allocator. These cost allocation methodologies are reasonable. From time to time, we adjust the basis for allocating the costs of a shared service among affiliates. Such changes in allocation methodologies are generally billed prospectively.

We also purchase services from our affiliates including telecommunication services, insurance, flight services and other support services such as legal, regulatory, finance and accounting, tax, human resources and executive support. Our affiliates charge us for these services based on FDC.

Commitments and Contingencies Disclosure [Abstract]  
Commitments, Contingencies and Other Items
Commitments, Contingencies and Other Items

We are subject to various claims, legal proceedings and other contingent liabilities, including the matters described below, which individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows. As a matter of course, we are prepared to both litigate these matters to judgment as needed, as well as to evaluate and consider reasonable settlement opportunities.

Irrespective of its merits, litigation may be both lengthy and disruptive to our operations and could cause significant expenditure and diversion of management attention. We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously-established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Amounts accrued for our litigation and non-income tax contingencies at December 31, 2019 and December 31, 2018 aggregated to approximately $50 million and $17 million, respectively, and are included in other current liabilities and other liabilities in our consolidated balance sheet as of such date. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.

In this Note, when we refer to a class action as "putative" it is because a class has been alleged, but not certified in that matter.

Switched Access Disputes

Subsidiaries of CenturyLink, Inc., including us, are among hundreds of companies involved in an industry-wide dispute, raised in nearly 100 federal lawsuits (filed between 2014 and 2016) that have been consolidated in the United States District Court for the Northern District of Texas for pretrial procedures. The disputes relate to switched access charges that local exchange carriers ("LECs") collect from interexchange carriers ("IXCs") for IXCs' use of LEC's access services. In the lawsuits, IXCs, including Sprint Communications Company L.P. ("Sprint") and various affiliates of Verizon Communications Inc. ("Verizon"), assert that federal and state laws bar LECs from collecting access charges when IXCs exchange certain types of calls between mobile and wireline devices that are routed through an IXC. Some of these IXCs have asserted claims seeking refunds of payments for access charges previously paid and relief from future access charges.

In November 2015, the federal court agreed with the LECs and rejected the IXCs' contention that federal law prohibits these particular access charges. Final judgments have been entered in the consolidated lawsuits and the IXCs are pursuing an appeal. Separately, some of the defendants, including us, have petitioned the FCC to address these issues on an industry-wide basis.

The outcome of these disputes and lawsuits, as well as any related regulatory proceedings that could ensue, are currently not predictable.

Billing Practices Suits

In June 2017, a former employee of CenturyLink filed an employment lawsuit against CenturyLink claiming that she was wrongfully terminated for alleging that CenturyLink charged some of its retail customers for products and services they did not authorize. Starting shortly thereafter and continuing since then, and based in part on the allegations made by the former employee, several legal proceedings have been filed.

In June 2017, McLeod v. CenturyLink, a putative consumer class action, was filed against CenturyLink in the U.S. District Court for the Central District of California alleging that it charged some of its retail customers for products and services they did not authorize. A number of other complaints asserting similar claims have been filed in other federal and state courts, as well. The lawsuits assert claims including fraud, unfair competition, and unjust enrichment. Also, in June 2017, Craig. v. CenturyLink, Inc., et al., a putative securities investor class action, was filed in U.S. District Court for the Southern District of New York, alleging that it failed to disclose material information regarding improper sales practices, and asserting federal securities law claims. A number of other cases asserting similar claims have also been filed.

Beginning June 2017, CenturyLink received several shareholder derivative demands addressing related topics. In August 2017, CenturyLink's Board of Directors formed a special litigation committee of outside directors to address the allegations of impropriety contained in the shareholder derivative demands. In April 2018, the special litigation committee concluded its review of the derivative demands and declined to take further action. Since then, derivative cases were filed. Two of these cases, Castagna v. Post and Pinsly v. Post, were filed in Louisiana state court in the Fourth Judicial District Court for the Parish of Ouachita. The remaining derivative cases were filed in federal court in Louisiana and Minnesota. These cases have been brought on behalf of CenturyLink against certain current and former officers and directors of the Company and seek damages for alleged breaches of fiduciary duties.

The consumer putative class actions, the securities investor putative class actions, and the federal derivative actions have been transferred to the U.S. District Court for the District of Minnesota for coordinated and consolidated pretrial proceedings as In Re: CenturyLink Sales Practices and Securities Litigation. Subject to confirmatory discovery and court approval, CenturyLink agreed to settle the consumer putative class actions for payments of $15.5 million to compensate class members and of up to $3.5 million for administrative costs. CenturyLink has accrued a contingent liability for those amounts. Certain class members may elect to opt out of the class settlement and pursue the resolution of their individual claims against us on these issues through various dispute resolution processes, including individual arbitration. One law firm claims to represent more than 22,000 potential class members. To the extent that a substantial number of class members, including many of the law firm’s alleged clients, meet the contractual requirements to arbitrate, elect to opt out of the settlement (or otherwise successfully exclude their individual claims), and actually pursue arbitrations, CenturyLink and we could incur a material amount of filing and other arbitrations fees in relation to the administration of those claims.

In July 2017, the Minnesota state attorney general filed State of Minnesota v. CenturyTel Broadband Services LLC, et al. in the Anoka County Minnesota District Court, alleging claims of fraud and deceptive trade practices relating to improper consumer sales practices.

CenturyLink has engaged in discussions regarding potential resolutions of these claims with a number of state attorneys general, and have entered into agreements settling the Minnesota suit and certain of the consumer practices claims asserted by state attorneys general. While CenturyLink does not agree with allegations raised in these matters, it has been willing to consider reasonable settlements where appropriate.

In 2019, we recorded a charge of approximately $33 million with respect to the above-described settlements and other consumer litigation related matters.

Locate Service Investigations

In June 2019, Minnesota and Arizona initiated investigations related to the timeliness of responses by certain of our vendors to requests for marking the location of underground telecommunications facilities. We, along with CenturyLink and its other subsidiaries are cooperating with the investigations. In February 2020, the Minnesota claims were settled. The terms of the settlement were not material to our consolidated results of operations or financial position.

Other Proceedings, Disputes and Contingencies

From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, administrative hearings of state public utility commissions relating primarily to our rates or services, actions relating to employee claims, various tax issues, environmental law issues, grievance hearings before labor regulatory agencies and miscellaneous third-party tort actions.

We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities, many of which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial during 2020 if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers. As with all litigation, we are vigorously defending these actions and, as a matter of course, are prepared to litigate these matters to judgment, as well as to evaluate and consider all reasonable settlement opportunities.

We are subject to various federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $100,000 in fines and penalties.

The outcome of these other proceedings described under this heading is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on us.

The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings currently viewed as immaterial by us may ultimately materially impact us.

These amounts do not represent our entire anticipated purchases in the future, but represent only those items for which we were contractually committed as of December 31, 2019.

Accounting Policies [Abstract]  
Consolidation
The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (referred to herein as affiliates) have not been eliminated.
Reclassifications
We reclassified certain prior period amounts to conform to the current period presentation. See Note 13—Products and Services Revenue for additional information. These changes had no impact on total operating revenue, total operating expenses or net income for any period presented.
Use of Estimates
Use of Estimates

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions we make when accounting for specific items and matters, including, but not limited to, revenue recognition, revenue reserves, network access costs, network access cost dispute reserves, investments, long-term contracts, customer retention patterns, allowance for doubtful accounts, depreciation, amortization, asset valuations, rates used for affiliate cost allocations, internal labor capitalization rates, recoverability of assets (including deferred tax assets), impairment assessments, taxes, certain liabilities and other provisions and contingencies, are reasonable, based on information available at the time they are made. These estimates, judgments and assumptions can materially affect the reported amounts of assets, liabilities and components of stockholder's equity as of the dates of the consolidated balance sheets, as well as the reported amounts of revenue, expenses and components of cash flows during the periods presented in our other consolidated financial statements. We also make estimates in our assessments of potential losses in relation to threatened or pending tax and legal matters. See Note 12—Income Taxes and Note 16—Commitments, Contingencies and Other Items for additional information.

For matters not related to income taxes, if a loss is considered probable and the amount can be reasonably estimated, we recognize an expense for the estimated loss. If we have the potential to recover a portion of the estimated loss from a third party, we make a separate assessment of recoverability and reduce the estimated loss if recovery is also deemed probable.

For matters related to income taxes, if we determine that the impact of an uncertain tax position is more likely than not to be sustained upon audit by the relevant taxing authority, then we recognize a benefit for the largest amount that is more likely than not to be sustained. No portion of an uncertain tax position will be recognized if the position has less than a 50% likelihood of being sustained. Interest is recognized on the amount of unrecognized benefit from uncertain tax positions.

For all of these and other matters, actual results could differ materially from our estimates.
Revenue Recognition
Revenue Recognition

We earn most of our consolidated revenue from contracts with customers, primarily through the provision of communications and other services. Revenue from contracts with customers is accounted for under Accounting Standards Codification ("ASC") 606. We also earn revenue from leasing arrangements (primarily fiber capacity agreements) and governmental subsidy payments, neither of which are accounted for under ASC 606.

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to receive in exchange for those goods or services. Revenue is recognized based on the following five-step model:

Identification of the contract with a customer;

Identification of the performance obligations in the contract;

Determination of the transaction price;

Allocation of the transaction price to the performance obligations in the contract; and

Recognition of revenue when, or as, we satisfy a performance obligation.

We provide an array of communications services to business and residential customers, including local voice, VPN, Ethernet, data, broadband, private line (including special access), network access, transport, voice, information technology, video and other ancillary services. We provide these services to a wide range of businesses, including global/international, enterprise, wholesale, government, small and medium business customers. Certain contracts also include the sale of equipment, which is not significant to our business.

We recognize revenue for services when we provide the applicable service or when control is transferred. Recognition of certain payments received in advance of services being provided is deferred. These advance payments include certain activation and certain installation charges. If the activation and installation charges are not separate performance obligations, we recognize them as revenue over the actual or expected contract term using historical experience, which ranges from one year to five years depending on the service. In most cases, termination fees or other fees on existing contracts that are negotiated in conjunction with new contracts are deferred and recognized over the new contract term.

For access services, we generally bill fixed monthly charges one month in advance to customers and recognize revenue as service is provided over the contract term in alignment with the customer's receipt of service. For usage and other ancillary services, we generally bill in arrears and recognize revenue as usage or delivery occurs.

In certain cases, customers may be permitted to modify their contracts. We evaluate the change in scope or price to identify whether the modification should be treated as a separate contract, whether the modification is a termination of the existing contract and creation of a new contract, or if it is a change to the existing contract.

Customer contracts are evaluated to determine whether the performance obligations are separable. If the performance obligations are deemed separable and separate earnings processes exist, the total transaction price that we expect to receive with the customer is allocated to each performance obligation based on its relative standalone selling price. The revenue associated with each performance obligation is then recognized as earned.

We periodically sell optical capacity on our network. These transactions are structured as indefeasible rights of use, commonly referred to as IRUs, which are the exclusive right to use a specified amount of capacity or fiber for a specified term, typically 10 to 20 years. In most cases, we account for the cash consideration received on transfers of optical capacity as ASC 606 revenue which is adjusted for the time value of money and is recognized ratably over the term of the agreement. Cash consideration received on transfers of dark fiber is accounted for as non-ASC 606 lease revenue, which we also recognize ratably over the term of the agreement. We do not recognize revenue on any contemporaneous exchanges of our optical capacity assets for other non-owned optical capacity assets.

In connection with offering products and services provided to the end user by third-party vendors, we review the relationship between us, the vendor and the end user to assess whether revenue should be reported on a gross or net basis. In assessing whether revenue should be reported on a gross or net basis, we consider whether we act as a principal in the transaction and control the goods and services used to fulfill the performance obligations associated with the transaction.

We have service level commitments pursuant to contracts with certain of our customers. To the extent that such service levels are not achieved or are otherwise disputed due to performance or service issues or other service interruptions or conditions, we will estimate the amount of credits to be issued and record a corresponding reduction to revenue in the period that the service level commitment was not met.

Customer payments are made based on billing schedules included in our customer contracts, which is typically on a monthly basis.

We defer (i.e. capitalize) incremental contract acquisition and fulfillment costs and recognize (or amortize) such costs over the average contract life. Our deferred contract costs for our customers have average amortization periods of approximately 30 months for consumer and up to 49 months for business. These deferred costs are monitored every period to reflect any significant change in assumptions.

See Note 3—Revenue Recognition for additional information.
Affiliate Transactions
Affiliate Transactions

We provide to our affiliates telecommunications services that we also provide to external customers. In addition, we provide to our affiliates computer system development and support services. Services provided by us to our affiliates are recognized as operating revenue-affiliates in our consolidated statements of operations. We also purchase services from our affiliates including telecommunications services, marketing and employee-related support services. Services provided to us from our affiliates are recognized as operating expenses-affiliates on our consolidated statements of operations. Because of the significance of the services we provide to our affiliates and our affiliates provide to us, 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.

We recognize intercompany charges at the amounts billed to us by our affiliates and we recognize intercompany revenue for services we bill to our affiliates. Regulatory rules require certain revenue and expenses to be recorded at market price or fully distributed cost. Our compliance with regulations is subject to review by regulators. Adjustments to intercompany charges that result from these reviews are recorded in the period they become known.

CenturyLink has cash management arrangements between certain of its subsidiaries that include lines of credit, affiliate obligations, capital contributions and dividends. As part of these cash management arrangements, an affiliate provides lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is transferred on a daily basis for centralized management by CenturyLink and most affiliate transactions are deemed to be settled at the time the transactions are recorded in our accounting records, with the resulting net balance at the end of each period reflected as advances to affiliates on the accompanying consolidated balance sheets. From time to time we declare and pay dividends to our parent, QSC, which are settled through the advances to affiliates, which has the net effect of reducing the amount of these advances. Dividends declared are reflected on our consolidated statements of stockholder's equity and the consolidated statements of cash flows reflects the changes in advances to affiliates as investing activities and changes in advances from affiliates as financing activities. Interest is assessed on the advances to/from affiliates on either the three-month U.S T-bill rate (for advances to affiliates) or CenturyLink’s weighted average borrowing rate (for advances from affiliates).

The affiliate obligations, net in current and noncurrent liabilities on our consolidated balance sheets primarily represents the cumulative allocation of expense, net of payments, associated with QCII’s pension plans and post-retirement benefits plans prior to the plan mergers. In 2015, we agreed to a plan to settle the outstanding affiliate obligations, net balance with QCII over a 30 year term. Under the plan, payments are scheduled to be made on a monthly basis. For the years ended December 31, 2019 and 2018, we made settlement payments of $76 million and $87 million, respectively, to QCII in accordance with the plan. Changes in the affiliate obligations, net are reflected in operating activities on our consolidated statements of cash flows.

In the normal course of business, we transfer assets to and from various affiliates through our parent, QSC, which are recorded through our equity. It is our policy to record asset transfers based on carrying values.
USF Surcharges, Gross Receipts Taxes and Other Surcharges
USF Surcharges, Gross Receipts Taxes and Other Surcharges

In determining whether to include in our revenue and expenses the taxes and surcharges collected from customers and remitted to government authorities, including USF surcharges, sales, use, value added and some excise taxes, we assess, among other things, whether we are the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where we do business. In jurisdictions where we determine that we are the principal taxpayer, we record the surcharges on a gross basis and include them in our revenue and costs of services and products. In jurisdictions where we determine that we are merely a collection agent for the government authority, we record the taxes on a net basis and do not include them in our revenue and costs of services and products.
Advertising Costs
Advertising Costs

Costs related to advertising are expensed as incurred and included in selling, general and administrative expenses in our consolidated statements of operations.
Legal Costs
Legal Costs

In the normal course of our business, we incur costs to hire and retain external legal counsel to advise us on regulatory, litigation and other matters. We expense these costs as the related services are received.
Income Taxes
Income Taxes

Our results are included in the CenturyLink consolidated federal income tax return and certain combined state income tax returns. CenturyLink allocates income tax expense to us based upon a separate return allocation method which results in income tax expense that approximates the expense that would result if we were a stand-alone entity. Our reported deferred tax assets and liabilities, as discussed below and in Note 12—Income Taxes, are primarily determined as a result of the application of the separate return allocation method and therefore the settlement of these amounts is dependent upon our parent, CenturyLink, rather than tax authorities. Our current expectation is that the vast majority of deferred tax assets and liabilities will be settled through our general intercompany obligation based upon the current CenturyLink policy. CenturyLink has the right to change their policy regarding settlement of these assets and liabilities at any time.

The provision for income taxes consists of an amount for taxes currently payable, an amount for tax consequences deferred to future periods and adjustments to our liabilities for uncertain tax positions. We record deferred income tax assets and liabilities reflecting future tax consequences attributable to differences between the financial statement carrying value of assets and liabilities and the tax basis 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.

We establish valuation allowances when necessary to reduce deferred income tax assets to the amounts that we believe are more likely than not to be recovered. Each quarter we evaluate the need to retain all or a portion of the valuation allowance on our deferred tax assets. See Note 12—Income Taxes for additional information.
Cash and Cash Equivalents
Cash and Cash Equivalents

Cash and cash equivalents include highly liquid investments that are readily convertible into cash and are not subject to significant risk from fluctuations in interest rates. As a result, the value at which cash and cash equivalents are reported in our consolidated financial statements approximates their fair value. Our cash collections are transferred to CenturyLink on a daily basis and our ultimate parent funds our cash disbursement needs. The net cash transferred to CenturyLink has been reflected as advances to affiliates in our consolidated balance sheets.

Book overdrafts occur when checks have been issued but have not been presented to our controlled disbursement bank accounts for payment. Disbursement bank accounts allow us to delay funding of issued checks until the checks are presented for payment. Until the issued checks are presented for payment, the book overdrafts are included in accounts payable on our consolidated balance sheet. This activity is included in the operating activities section in our consolidated statements of cash flows.
Restricted Cash and Securities
Restricted Cash and Securities

Restricted cash and securities consists primarily of cash and investments that serve to collateralize certain performance and operating obligations. Restricted cash and securities are recorded as current and non-current assets in the consolidated balance sheets depending on the duration of the restriction and the purpose for which the restriction exists. Restricted securities are stated at cost which approximates fair value as of December 31, 2019 and 2018.
Accounts Receivable and Allowance for Doubtful Accounts
Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recognized based upon the amount due from customers for the services provided or at cost for purchased and other receivables less an allowance for doubtful accounts. The allowance for doubtful accounts receivable reflects our best estimate of probable losses inherent in our receivable portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence. We generally consider our accounts past due if they are outstanding over 30 days. Our collection process varies by the customer segment, amount of the receivable, and our evaluation of the customer's credit risk. Our past due accounts are written off against our allowance for doubtful accounts when collection is considered to be not probable. Any recoveries of accounts previously written off are generally recognized as a reduction in bad debt expense in the period received. The carrying value of accounts receivable, net of the allowance for doubtful accounts, approximates fair value.

Property, Plant and Equipment
Property, Plant and Equipment

As a result of our indirect acquisition by CenturyLink, property, plant and equipment acquired at the time of acquisition was recorded based on its estimated fair value as of the acquisition date. Subsequently purchased and constructed property, plant and equipment are recorded at cost. Property, plant and equipment is depreciated primarily using the straight-line group method. Under the straight-line group method, assets dedicated to providing telecommunications services (which comprise the majority of our property, plant and equipment) that have similar physical characteristics, use and expected useful lives are pooled for purposes of depreciation and tracking. The equal life group procedure is used to establish each pool's average remaining useful life. Generally, under the straight-line group method, when an asset is sold or retired in the course of normal business activities, the cost is deducted from property, plant and equipment and charged to accumulated depreciation without recognition of a gain or loss. A gain or loss is recognized in our consolidated statements of operations only if a disposal is unusual. Leasehold improvements are amortized over the shorter of the useful lives of the assets or the expected lease term. Expenditures for maintenance and repairs are expensed as incurred. Interest is capitalized during the construction phase of network and other internal-use capital projects. Employee-related costs for construction of network and other internal use assets are also capitalized during the construction phase. Property, plant and equipment supplies used internally are carried at average cost, except for significant individual items for which cost is based on specific identification.

We perform annual internal reviews to evaluate the reasonableness of the depreciable lives for our property, plant and equipment. Our reviews utilize models that take into account actual usage, physical wear and tear, replacement history, assumptions about technology evolution and, in certain instances, actuarially determined probabilities to estimate the remaining useful life of our asset base. Our remaining useful life assessments assess the possible loss in service value of assets that may precede the physical retirement. Assets shared among many customers may lose service value as those customers reduce their use of the network. However, the asset is not retired until all customers no longer utilize the asset and we determine there is no alternative use for the asset.

We review long-lived tangible assets for impairment whenever facts and circumstances indicate that the carrying amounts of the assets may not be recoverable. For assessment purposes, long-lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, absent a material change in operations. An impairment loss is recognized only if the carrying amount of the asset group is not recoverable and exceeds its estimated fair value. Recoverability of the asset group to be held and used is assessed by comparing the carrying amount of the asset group to the estimated undiscounted future net cash flows expected to be generated by the asset group. If the asset group's carrying value is not recoverable, we recognize an impairment charge for the amount by which the carrying amount of the asset group exceeds its estimated fair value.
Goodwill, Customer Relationships and Other Intangible Assets
Goodwill, Customer Relationships and Other Intangible Assets

Intangible assets arising from business combinations, such as goodwill, customer relationships and capitalized software are initially recorded at estimated fair value. We amortize customer relationships primarily over an estimated life of ten years, using either the sum-of-the-years-digits or the straight-line methods, depending on the type of customer. We amortize capitalized software using the straight-line method over estimated lives ranging up to seven years. Other intangible assets not arising from business combinations are initially recorded at cost.

Internally used software, whether purchased or developed by us, is capitalized and amortized using the straight-line method over its estimated useful life. We have capitalized certain costs associated with software such as costs of employees devoting time to the projects and external direct costs for materials and services. Costs associated with software to be used for internal purposes are expensed until the point at which the project has reached the development stage. Subsequent additions, modifications or upgrades to internal-use software are capitalized only to the extent that they allow the software to perform a task it previously did not perform. Software maintenance, data conversion and training costs are expensed in the period in which they are incurred. We review the remaining economic lives of our capitalized software annually. Capitalized software is included in other intangible assets, net, in our consolidated balance sheets.

We are required to assess goodwill for impairment at least annually, or more frequently, if an event occurs or circumstances change that would indicate an impairment may have occurred. We are required to write-down the value of goodwill in periods in which the carrying amount of the reporting unit equity exceeds the estimated fair value of the equity of the reporting unit limited to the goodwill balance. The impairment assessment is performed at the reporting unit level. We have determined that our operations consist of one reporting unit, consistent with our determination that our business consists of one operating segment. See Note 2—Goodwill, Customer Relationships and Other Intangible Assets for additional information.
Pension and Post-Retirement Benefits
Pension and Post-Retirement Benefits

A substantial portion of our active and retired employees participate in the CenturyLink Combined Pension Plan. On December 31, 2014, the QCII pension plan and a pension plan of an affiliate were merged into the CenturyLink Retirement Plan. The CenturyLink Retirement Plan was renamed the CenturyLink Combined Pension Plan. Prior to the pension plan merger, the above-noted employees participated in the QCII pension plan. In addition, certain of our employees participate in CenturyLink's post-retirement health care and life insurance benefit plans. CenturyLink allocates service costs relating to pension and post-retirement health care and life insurance benefits to us and its other affiliates. The amounts contributed by us through CenturyLink are not segregated or restricted to pay amounts due to our employees and may be used to provide benefits to other employees of CenturyLink. The allocation of the service costs to us is based upon our employees who are currently earning benefits under the plans.

For further information on qualified pension, post-retirement and other post-employment benefit plans, see CenturyLink's annual report on Form 10-K for the year ended December 31, 2019.
Recently Adopted Accounting Pronouncements; Recent Accounting Pronouncements
Recently Adopted Accounting Pronouncements

During 2019, we adopted Accounting Standards Update ("ASU") 2016-02, "Leases (ASC 842"). In 2018, we adopted Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” and ASU 2017-04, "Simplifying the Test for Goodwill Impairment".

Each of these is described further below.

Leases

We adopted Accounting Standards Update ("ASU") 2016-02, "Leases (ASC 842)", as of January 1, 2019, using the non-comparative transition option pursuant to ASU 2018-11. Therefore, we have not restated comparative period financial information for the effects of ASC 842, and we will not make the new required lease disclosures for comparative periods beginning before January 1, 2019. Instead, we recognized ASC 842's cumulative effect transition adjustment (discussed below) as of January 1, 2019. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things (i) allowed us to carry forward the historical lease classification; (ii) did not require us to reassess whether any expired or existing contracts are or contain leases under the new definition of a lease; and (iii) did not require us to reassess whether previously capitalized initial direct costs for any existing leases would qualify for capitalization under ASC 842. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements. We did not elect the hindsight practical expedient regarding the likelihood of exercising a lessee purchase option or assessing any impairment of right-of-use assets for existing leases.
On March 5, 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-01, "Leases (ASC 842): Codification Improvements", effective for public companies for fiscal years beginning after December 15, 2019. The new ASU aligns the guidance in ASC 842 for determining fair value of the underlying asset by lessors that are not manufacturers or dealers, with that of existing guidance. As a result, the fair value of the underlying asset at lease commencement is its cost, reflecting any volume or trade discounts that may apply. However, if there has been a significant lapse of time between when the underlying asset is acquired and when the lease commences, the definition of fair value (in ASC 820, "Fair Value Measurement") should be applied. More importantly, the ASU also exempts both lessees and lessors from having to provide certain interim disclosures in the fiscal year in which a company adopts the new leases standard. Early adoption permits public companies to adopt concurrent with the transition to ASC 842 on leases. We adopted ASU 2019-01 as of January 1, 2019.

Adoption of the new standards resulted in the recording of operating lease assets and operating lease liabilities of approximately $126 million and $133 million, respectively, as of January 1, 2019. The standards did not materially impact our consolidated net earnings and had no material impact on cash flows. Our financial position for reporting periods beginning on or after January 1, 2019 is presented under the new guidance, as discussed above, while prior period amounts are not adjusted and continue to be reported in accordance with previous guidance.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") ASU 2014-09 which replaces virtually all existing generally accepted accounting principles on revenue recognition with a principles-based approach for determining revenue recognition using a new five step model. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also includes new accounting principles related to the deferral and amortization of contract acquisition and fulfillment costs.

We adopted the new revenue recognition standard on January 1, 2018 using the modified retrospective transition method applying the rules to all open contracts existing as of January 1, 2018. During the year ended December 31, 2018, we recorded a cumulative catch-up adjustment that increased our retained earnings by $141 million, net of $49 million of income taxes.

See Note 3—Revenue Recognition for additional information.

Income Taxes

In October 2016, the FASB issued ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” ("ASU 2016-16"). ASU 2016-16 eliminates the current prohibition on the recognition of the income tax effects on the transfer of assets among our subsidiaries. After adoption of ASU 2016-16, the income tax effects associated with these asset transfers, except for the transfer of inventory, will be recognized in the period the asset is transferred versus the current deferral and recognition upon either the sale of the asset to a third party or over the remaining useful life of the asset. We adopted ASU 2016-16 on January 1, 2018. The adoption of ASU 2016-16 did not have a material impact to our consolidated financial statements.

Goodwill Impairment

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 simplifies the impairment testing for goodwill by changing the measurement for goodwill impairment. Under current rules, we are required to compute the fair value of goodwill to measure the impairment amount if the carrying value of a reporting unit exceeds its fair value. Under ASU 2017-04, the goodwill impairment charge will equal the excess of the reporting unit carrying value above fair value, limited to the amount of goodwill assigned to the reporting unit.

We elected to early adopt the provisions of ASU 2017-04 as of October 1, 2018.

Recently Issued Accounting Pronouncements

Financial Instruments

In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments". The primary impact of ASU 2016-13 for us is a change in the model for the recognition of credit losses related to our financial instruments from an incurred loss model, which recognized credit losses only if it was probable that a loss had been incurred, to an expected loss model, which requires our management team to estimate the total credit losses expected on the portfolio of financial instruments.

We are in the process of implementing the model for the recognition of credit losses related to our financial instruments, new processes and internal controls to assist us in the application of the new standard. The cumulative effect of initially applying the new standard on January 1, 2020 is not material.
