Accounting Policies [Abstract]
Background	(1) Background General We are an international facilities-based communications provider (that is, a provider that owns or leases a substantial portion of the property, plant and equipment necessary to provide our services) of a broad range of integrated communications services. We created our communications network by constructing our own assets and through a combination of purchasing other companies and purchasing or leasing facilities from others. We designed our network to provide communications services that employ and take advantage of rapidly improving underlying optical, Internet Protocol, computing and storage technologies. Effective November 1, 2017, we were acquired by CenturyLink in a cash and stock transaction, including the assumption of our debt (the "CenturyLink Merger"). Basis of Presentation Our consolidated balance sheet as of December 31, 2018, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission ("SEC"); however, in our opinion, the disclosures made are adequate to make the information presented not misleading. We believe that these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations and cash flows for the first three months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2018. The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (CenturyLink and its other subsidiaries, referred to herein as affiliates) have not been eliminated. Due to exchange restrictions and other conditions, effective at the end of the third quarter of 2015, we deconsolidated our Venezuelan subsidiary and began accounting for our investment in our Venezuelan subsidiary using the cost method of accounting. The factors that led to our conclusions at the end of the third quarter of 2015 continued to exist through the first quarter of 2019. We reclassified certain prior period amounts to conform to the current period presentation, including the categorization of our revenue for three months ended March 31, 2019 and 2018. Segments Our operations are integrated into and reported as part 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 have one reportable segment. Recently Adopted Accounting Pronouncements We adopted Accounting Standards Update ("ASU") 2016-02, Leases (Accounting Standard Codification "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 will recognize 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 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 for fair value of the underlying asset by lessors that are not manufacturers or dealers in ASC 842, 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 standard resulted in the recording of operating lease assets and operating lease liabilities of approximately $1.3 billion and $1.4 billion, respectively, as of January 1, 2019. The standard did not materially impact our consolidated net earnings in the first quarter of 2019 and had no impact on cash flows. Recently Issued Accounting Pronouncements Financial Instruments In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). 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 currently reviewing the requirements of the standard and evaluating the impact on our consolidated financial statements. We are required to adopt the provisions of ASU 2016-13 no later than January 1, 2020. We expect to adopt ASU 2016-13 on January 1, 2020 and recognize the impacts through a cumulative adjustment to retained earnings as of the date of adoption. Subsequent Event As of the date of this report, $90 million of distributions were made to our parent in the second quarter of 2019.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill, Customer Relationships and Other Intangible Assets

(2) Goodwill, Customer Relationships and Other Intangible Assets

Goodwill, customer relationships and other intangible assets consisted of the following:



	March 31, 2019		December 31, 2018
	(Dollars in millions)
Goodwill	$	7,412	11,119
Customer relationships, less accumulated amortization of $1,006 and $833	$	7,398	7,567
Other intangible assets subject to amortization:
Trade names, less accumulated amortization of $37 and $30	93		100
Developed technology, less accumulated amortization of $84 and $67	329		310
Total other intangible assets, net	$	422	410

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

We are required to perform an impairment test related to our goodwill annually, which we perform as of October 31, or sooner if an indicator of impairment occurs. Due to the decline in CenturyLink's stock price, we incurred an event in the first quarter of 2019 that triggered impairment testing. Due to this impairment indicator, we evaluated our goodwill as of March 31, 2019.

When we performed our October 31, 2018 annual impairment test, we estimated the fair value of equity by considering both a market approach and a discounted cash flow method. The market approach method includes the use of 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 beyond the cash flows from the discrete projection period. 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 as of March 31, 2019. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry which have historically supported a range of fair values of annualized revenue and EBITDA multiples between 2.1x and 4.9x and 4.9x and 9.8x, respectively. We selected a revenue and EBITDA multiple within this range. For the three months ended March 31, 2019, based on our assessments performed as described above, we concluded that the estimated fair value was less than our carrying value of equity as of the date of our triggering event during the first quarter. As a result, we recorded a non-cash, non-tax-deductible goodwill impairment charge of $3.7 billion for the three months ended March 31, 2019.

The market multiples approach that we used incorporates significant estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of other cost synergies. In developing the market multiple, we also considered observed trends of our industry participants. Our failure to attain these forecasted results or changes in trends could result in future impairments. 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. Continued declines in our profitability, cash flows or the sustained, historically low trading prices of CenturyLink's common stock, may result in further impairment.

Total amortization expense for intangible assets for the three months ended March 31, 2019 and 2018 was $193 million and $194 million, respectively. As of March 31, 2019, the gross carrying amount of goodwill, customer relationships, indefinite-life and other intangible assets was $16.4 billion.

We estimate that total amortization expense for intangible assets for the years ending December 31, 2019 through 2023 will be as follows:



	(Dollars in millions)
2019 (remaining nine months)	$	599
2020	800
2021	800
2022	796

(1)	Gross customer receivables of $716 and $723 million, net of allowance for doubtful accounts of $17 and $11 million, at March 31, 2019 and December 31, 2018, respectively.

Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or 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 seven years depending on the service. Contract liabilities are included within deferred revenue in our consolidated balance sheets.

The following table provides information about revenue recognized for the three months ended March 31, 2019 and 2018:



	Three Months Ended

Revenue recognized in the period from:
Amounts included in contract liability at the beginning of the period (January 1, 2019 and 2018, respectively)	$	95	97
Performance obligations satisfied in previous periods	—		—

Performance Obligations

As of March 31, 2019, our estimated revenue expected to be recognized in the future related to performance obligations associated with customer contracts (including affiliates) that are unsatisfied (or partially satisfied) is approximately $5.0 billion. We expect to recognize approximately 75% of this revenue through 2021, with the balance recognized thereafter.

We do not disclose the value of unsatisfied performance obligations for contracts for which we are contractually entitled to bill pre-determined amounts for future services (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.

Contract Costs

The following table provides changes in our contract acquisition costs and fulfillment costs:



	Three Months Ended March 31, 2019					Three Months Ended March 31, 2018
	(Dollars in millions)
	Acquisition Costs			Fulfillment Costs		Acquisition Costs		Fulfillment Costs

Amortization	(8		)	(13	)	(2	)	(2	)
End of period balance	$	74		97		26		35

Acquisition costs include commission fees 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 expected contract term of 12 to 60 months for our 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 these deferred costs that are expected 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.

(7) Products and Services Revenue

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


•	IP and Data Services, which include primarily VPN data networks, Ethernet, IP, video (including our CDN services and Vyvx broadcast services) and other ancillary services;


•	Transport and Infrastructure, which includes private line (including business data services), wavelength, colocation and data center services, including cloud, hosting and application management solutions, professional services, network security services, dark fiber services and other ancillary services;


•	Voice and Collaboration, which includes primarily TDM voice services, VOIP and other ancillary services;


•	Other, which includes sublease rental income and information technology services and managed services, which may be purchased in conjunction with our other network services; and


•	Affiliate Services, we provide our affiliates with telecommunication services that we also provide to external customers.

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:



	Three Months Ended March 31, 2019		Three Months Ended March 31, 2018
	(Dollars in millions)
IP and Data Services	$	979	1,003
Transport and Infrastructure	658		676
Voice and Collaboration	352		382
Other	2		1
Affiliate Services	55		25
Total operating revenue	$	2,046	2,087

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 total amount of such surcharges and transaction taxes that we included in revenue aggregated $109 million and $107 million for the three months ended March 31, 2019 and March 31, 2018, respectively. These USF surcharges, where we record revenue and transaction taxes, 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.

Leases

Leases [Abstract]

Leases

(4) Leases

Effective January 1, 2019, we adopted ASC 842 using the non-comparative transition option of applying the new standard at the adoption date. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard. This allowed us to carry forward the historical lease classification. Adoption of the new standard resulted in the recording of additional net operating lease assets and operating lease liabilities of approximately $1.3 billion and $1.4 billion, respectively, as of January 1, 2019. Additionally, the new standard resulted in the recording of approximately $30 million for both net lease assets and net lease liabilities with affiliates as of January 1, 2019, which are included in the lease balances. Financial position for reporting periods beginning on or after January 1, 2019 are presented under the new guidance, while prior periods amounts are not adjusted and continue to be reported in accordance with previous guidance.

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. 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 including 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.

Lease expense consisted of the following:

Leases

(4) Leases

Effective January 1, 2019, we adopted ASC 842 using the non-comparative transition option of applying the new standard at the adoption date. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard. This allowed us to carry forward the historical lease classification. Adoption of the new standard resulted in the recording of additional net operating lease assets and operating lease liabilities of approximately $1.3 billion and $1.4 billion, respectively, as of January 1, 2019. Additionally, the new standard resulted in the recording of approximately $30 million for both net lease assets and net lease liabilities with affiliates as of January 1, 2019, which are included in the lease balances. Financial position for reporting periods beginning on or after January 1, 2019 are presented under the new guidance, while prior periods amounts are not adjusted and continue to be reported in accordance with previous guidance.

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. 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 including 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.

Covenants

The term loan and senior notes of Level 3 Parent, LLC and Level 3 Financing, Inc. contain extensive affirmative and negative covenants. Such covenants include, among other things and subject to certain significant exceptions, restrictions on their ability to declare or pay dividends, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, engage in transactions with their affiliates including CenturyLink and its other subsidiaries, dispose of assets and merge or consolidate with any other person. Also, Level 3 Parent, LLC, as well as Level 3 Financing, Inc., will be required to offer to purchase certain of its long-term debt securities under certain circumstances in connection with a "change of control" of Level 3 Parent, LLC.

Certain of CenturyLink's and our debt instruments contain 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.

Restructuring and Related Activities [Abstract]

Severance and Leased Real Estate

(6) Severance and Leased Real Estate

Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workload demands due to the loss of customers purchasing certain services.

We have recognized liabilities to reflect our estimates of the fair values of the existing lease obligations for real estate which we have ceased using, net of estimated sublease rentals. In accordance with transitional guidance under the new lease standard (ASC 842), the existing lease obligation of $47 million as of January 1, 2019 has been netted against the operating lease right of use assets at adoption. For additional information, see Note 4—Leases to our consolidated financial statements in Item 1 of Part I of this report.

Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or 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 seven years depending on the service. Contract liabilities are included within deferred revenue in our consolidated balance sheets.

The following table provides information about revenue recognized for the three months ended March 31, 2019 and 2018:

Performance Obligations

As of March 31, 2019, our estimated revenue expected to be recognized in the future related to performance obligations associated with customer contracts (including affiliates) that are unsatisfied (or partially satisfied) is approximately $5.0 billion. We expect to recognize approximately 75% of this revenue through 2021, with the balance recognized thereafter.

We do not disclose the value of unsatisfied performance obligations for contracts for which we are contractually entitled to bill pre-determined amounts for future services (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.

Contract Costs

The following table provides changes in our contract acquisition costs and fulfillment costs:

Acquisition costs include commission fees 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 expected contract term of 12 to 60 months for our 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 these deferred costs that are expected 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.

(7) Products and Services Revenue

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


•	IP and Data Services, which include primarily VPN data networks, Ethernet, IP, video (including our CDN services and Vyvx broadcast services) and other ancillary services;


•	Transport and Infrastructure, which includes private line (including business data services), wavelength, colocation and data center services, including cloud, hosting and application management solutions, professional services, network security services, dark fiber services and other ancillary services;


•	Voice and Collaboration, which includes primarily TDM voice services, VOIP and other ancillary services;


•	Other, which includes sublease rental income and information technology services and managed services, which may be purchased in conjunction with our other network services; and


•	Affiliate Services, we provide our affiliates with telecommunication services that we also provide to external customers.

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:



	Three Months Ended March 31, 2019		Three Months Ended March 31, 2018

Total operating revenue	$	2,046	2,087

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 total amount of such surcharges and transaction taxes that we included in revenue aggregated $109 million and $107 million for the three months ended March 31, 2019 and March 31, 2018, respectively. These USF surcharges, where we record revenue and transaction taxes, 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.

Commitments, Contingencies and Other Items	Mar. 31, 2019
Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Other Items	(9) 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 contingencies at March 31, 2019 aggregated to approximately $70 million 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. Peruvian Tax Litigation In 2005, the Peruvian tax authorities ("SUNAT") issued tax assessments against one of our Peruvian subsidiaries asserting $26 million of additional income tax withholding and value-added taxes ("VAT"), penalties and interest for calendar years 2001 and 2002 on the basis that the Peruvian subsidiary incorrectly documented its importations. After taking into account the developments described below, as well as the accrued interest and foreign exchange effects, we believe the total amount of exposure is $10 million at March 31, 2019. We challenged the assessments via administrative and then judicial review processes. In October 2011, the highest administrative review tribunal (the "Tribunal") decided the central issue underlying the 2002 assessments in SUNAT's favor. We appealed the Tribunal's decision to the first judicial level, which decided the central issue in favor of Level 3. SUNAT and we filed cross-appeals with the court of appeal. In May 2017, the court of appeal issued a decision reversing the first judicial level. In June 2017, we filed an appeal of the decision to the Supreme Court of Justice, the final judicial level. Oral argument was held before the Supreme Court of Justice in October 2018. A decision on this case is pending. In October 2013, the Tribunal decided the central issue underlying the 2001 assessments in SUNAT’s favor. We appealed that decision to the first judicial level in Peru, which decided the central issue in favor of SUNAT. In June 2017, we filed an appeal with the court of appeal. In November 2017, the court of appeals issued a decision affirming the first judicial level and we filed an appeal of the decision to the Supreme Court of Justice. That appeal is pending. Brazilian Tax Claims In December 2004, March 2009, April 2009 and July 2014, the São Paulo state tax authorities issued tax assessments against one of our Brazilian subsidiaries for the Tax on Distribution of Goods and Services (“ICMS”) with respect to revenue from leasing certain assets (in the case of the December 2004, March 2009 and July 2014 assessments) and revenue from the provision of Internet access services (in the case of the April 2009 and July 2014 assessments), by treating such activities as the provision of communications services, to which the ICMS tax applies. In September 2002, July 2009 and May 2012, the Rio de Janeiro state tax authorities issued tax assessments to the same Brazilian subsidiary on similar issues. We have filed objections to these assessments, arguing that the lease of assets and the provision of Internet access are not communication services subject to ICMS. The objections to the September 2002, December 2004 and March 2009 assessments were rejected by the respective state administrative courts, and we have appealed those decisions to the judicial courts. In October 2012 and June 2014, we received favorable rulings from the lower court on the December 2004 and March 2009 assessments regarding equipment leasing, but those rulings are subject to appeal by the state. No ruling has been obtained with respect to the September 2002 assessment. The objections to the April and July 2009 and May 2012 assessments are still pending final administrative decisions. The July 2014 assessment was confirmed during the fourth quarter of 2014 at the first administrative level, and we appealed this decision to the second administrative level. We are vigorously contesting all such assessments in both states and, in particular, view the assessment of ICMS on revenue from equipment leasing to be without merit. These assessments, if upheld, could result in a loss of up to $37 million at March 31, 2019 in excess of the accruals established for these matters. Qui Tam Action We were notified in late 2017 of a qui tam action pending against Level 3 Communications, Inc. and others in the United States District Court for the Eastern District of Virginia, captioned United States of America ex rel., Stephen Bishop v. Level 3 Communications, Inc. et al. The original qui tam complaint was filed under seal on November 26, 2013, and an amended complaint was filed under seal on June 16, 2014. The court unsealed the complaints on October 26, 2017. The amended complaint alleges that we, principally through two former employees, submitted false claims and made false statements to the government in connection with two government contracts. The relator seeks damages in this lawsuit of approximately $50 million, subject to trebling, plus statutory penalties, pre-and-post judgment interest, and attorney’s fees. The case is currently stayed. We are evaluating our defenses to the claims. At this time, we do not believe it is probable we will incur a material loss. If, contrary to our expectations, the plaintiff prevails in this matter and proves damages at or near $50 million, and is successful in having those damages trebled, the outcome could have a material adverse effect on our results of operations in the period in which a liability is recognized and on our cash flows for the period in which any damages are paid. Several people, including two former Level 3 employees, were indicted in the United States District Court for the Eastern District of Virginia on October 3, 2017, and charged with, among other things, accepting kickbacks from a subcontractor, who was also indicted, for work to be performed under a prime government contract. Of the two former employees, one entered a plea agreement, and the other is deceased. We are fully cooperating in the government’s investigations in this matter. Letters of Credit It is customary for us to use various financial instruments in the normal course of business. These instruments include letters of credit which are conditional commitments issued on our behalf in accordance with specified terms and conditions. As of both March 31, 2019 and December 31, 2018, we had outstanding letters of credit or other similar obligations of approximately $30 million and $30 million, respectively, of which $24 million and $24 million are collateralized by cash that is reflected on the consolidated balance sheets as restricted cash and securities. 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 or proceedings 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 in the coming 24 months 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 foreign, 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 individually is reasonably expected to exceed $100,000 in fines and penalties. The outcome of these other proceedings is not predictable.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our consolidated balance sheet as of December 31, 2018, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission ("SEC"); however, in our opinion, the disclosures made are adequate to make the information presented not misleading. We believe that these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations and cash flows for the first three months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2018. The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (CenturyLink and its other subsidiaries, referred to herein as affiliates) have not been eliminated. Due to exchange restrictions and other conditions, effective at the end of the third quarter of 2015, we deconsolidated our Venezuelan subsidiary and began accounting for our investment in our Venezuelan subsidiary using the cost method of accounting. The factors that led to our conclusions at the end of the third quarter of 2015 continued to exist through the first quarter of 2019. We reclassified certain prior period amounts to conform to the current period presentation, including the categorization of our revenue for three months ended March 31, 2019 and 2018.
Segments	Segments Our operations are integrated into and reported as part 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 have one reportable segment.
New Accounting Pronouncements	Recently Adopted Accounting Pronouncements We adopted Accounting Standards Update ("ASU") 2016-02, Leases (Accounting Standard Codification "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 will recognize 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 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 for fair value of the underlying asset by lessors that are not manufacturers or dealers in ASC 842, 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 standard resulted in the recording of operating lease assets and operating lease liabilities of approximately $1.3 billion and $1.4 billion, respectively, as of January 1, 2019. The standard did not materially impact our consolidated net earnings in the first quarter of 2019 and had no impact on cash flows. Recently Issued Accounting Pronouncements Financial Instruments In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13"). 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 currently reviewing the requirements of the standard and evaluating the impact on our consolidated financial statements. We are required to adopt the provisions of ASU 2016-13 no later than January 1, 2020. We expect to adopt ASU 2016-13 on January 1, 2020 and recognize the impacts through a cumulative adjustment to retained earnings as of the date of adoption.
