Basis of Presentation	Basis of Presentation Liberty Global plc ( Liberty Global ) is a public limited company organized under the laws of England and Wales. In these notes, the terms “we,” “our,” “our company” and “us” may refer, as the context requires, to Liberty Global or collectively to Liberty Global and its subsidiaries. We are an international provider of video, broadband internet, fixed-line telephony, mobile and other communications services to residential customers and businesses in Europe. Our continuing operations comprise businesses that provide residential and business-to-business ( B2B ) communication services in (i) the United Kingdom ( U.K. ) and Ireland through Virgin Media Inc. ( Virgin Media ), a wholly-owned subsidiary of Liberty Global , (ii) Belgium through Telenet Group Holding N.V. ( Telenet ), a 57.7% -owned subsidiary, and (iii) Switzerland and Poland through UPC Holding B.V. and (iv) Slovakia through UPC Broadband Slovakia s.r.o. UPC Holding B.V. and UPC Broadband Slovakia s.r.o., which are each wholly-owned subsidiaries of Liberty Global , are collectively referred to herein as “ UPC Holding .” In addition, we own a 50% noncontrolling interest in the VodafoneZiggo JV (as defined in note 5 ), which provides video, broadband internet, fixed-line telephony, mobile and B2B services in the Netherlands. In addition, (i) we currently provide residential and B2B communication services in Germany through Unitymedia GmbH ( Unitymedia ) and in Romania, Hungary and the Czech Republic through UPC Holding B.V. and (ii) through July 31, 2018, we provided residential and B2B communication services in Austria through UPC Holding B.V. On May 9, 2018, we reached an agreement to sell our operations in Germany, Romania, Hungary and the Czech Republic, and on July 31, 2018, we completed the sale of our operations in Austria. In these condensed consolidated financial statements, the operations in each of these countries are reflected as discontinued operations for all periods presented. For additional information regarding these pending and completed dispositions, see note 4 . Prior to the completion of the Split-off Transaction (as defined and described in note 4 ), we also provided residential and B2B services in (i) 18 countries, predominantly in Latin America and the Caribbean, through Cable &Wireless Communications Limited ( C&W ), (ii) Chile through VTR.com SpA ( VTR ) and (iii) Puerto Rico through Liberty Cablevision of Puerto Rico LLC ( Liberty Puerto Rico ). C&W and VTR were wholly-owned subsidiaries, and Liberty Puerto Rico was an entity in which we held a 60.0% ownership interest. C&W also provided (a) B2B services in certain other countries in Latin America and the Caribbean and (b) wholesale services over its sub-sea and terrestrial networks that connected over 40 markets in that region. The operations of C&W , VTR , Liberty Puerto Rico and certain other entities that were associated with our businesses in Latin America and the Caribbean are collectively referred to herein as the “ LiLAC Group .” As a result of the Split-off Transaction , the entities attributed to the LiLAC Group are reflected as discontinued operations in our condensed consolidated statements of operations and cash flows for the three and six months ended June 30, 2017. Unless otherwise noted, the amounts presented in these notes relate only to our continuing operations. Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ( U.S. GAAP ) and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all of the information required by U.S. GAAP or Securities and Exchange Commission rules and regulations for complete financial statements. In the opinion of management, these financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with our 2017 consolidated financial statements and notes thereto included in our 2017 Annual Report on Form 10-K (our 10-K ). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, allowances for uncollectible accounts, certain components of revenue, programming and copyright costs, deferred income taxes and related valuation allowances, loss contingencies, fair value measurements, impairment assessments, capitalization of internal costs associated with construction and installation activities, useful lives of long-lived assets, share-based compensation and actuarial liabilities associated with certain benefit plans. Actual results could differ from those estimates. Unless otherwise indicated, ownership percentages and convenience translations into United States ( U.S. ) dollars are calculated as of June 30, 2018 .

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes and Recent Accounting Pronouncements Accounting Changes ASU 2014-09 In May 2014, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2014-09, Revenue from Contracts with Customers ( ASU 2014-09 ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services to customers. We adopted ASU 2014-09 effective January 1, 2018 by recording the cumulative effect of the adoption to our accumulated deficit. We applied the new standard to contracts that were not complete at January 1, 2018. The comparative information for the three and six months ended June 30, 2017 contained within these condensed consolidated financial statements and notes has not been restated and continues to be reported under the accounting standards in effect for such period. The implementation of ASU 2014-09 did not have a material impact on our consolidated financial statements. The principal impacts of ASU 2014-09 on our revenue recognition policies relate to our accounting for (i) time-limited discounts and free service periods provided to our customers and (ii) certain upfront fees charged to our customers, as follows: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under previous accounting rules, we recognized revenue, net of discounts, during the promotional periods and did not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition for those contracts that contain substantive termination penalties is accelerated, as the impact of the discounts or free service periods is recognized uniformly over the contractual period. For contracts that do not have substantive termination penalties, we continue to record the impacts of partial or full discounts during the applicable promotional periods. • When we enter into contracts to provide services to our customers, we often charge installation or other upfront fees. Under previous accounting rules, installation fees related to services provided over our cable networks were recognized as revenue during the period in which the installation occurred to the extent these fees were equal to or less than direct selling costs. Under ASU 2014-09 , these fees are generally deferred and recognized as revenue over the contractual period, or longer if the upfront fee results in a material renewal right. ASU 2014-09 also impacted our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our previous policy, these costs were expensed as incurred unless the costs were in the scope of another accounting topic that allowed for capitalization. Under ASU 2014-09 , certain upfront costs associated with contracts that have substantive termination penalties and a term of one year or more are recognized as assets and amortized to operating costs and expenses over the applicable period benefited. For additional information regarding our adoption of ASU 2014-09 , see note 3 . The cumulative effect of the adoption of ASU 2014-09 on our summary balance sheet information as of January 1, 2018 is as follows: Balance at December 31, 2017 ASU 2014-09 Adjustments Balance at January 1, 2018 in millions Assets: Trade receivables, net $ 1,411.0 (0.7 ) $ 1,410.3 Current assets of discontinued operations $ 268.1 98.2 $ 366.3 Other current assets $ 351.9 76.6 $ 428.5 Investments and related note receivables (a) $ 6,671.4 191.2 $ 6,862.6 Deferred tax assets $ 3,133.1 (16.0 ) $ 3,117.1 Long-term assets of discontinued operations $ 11,141.1 29.1 $ 11,170.2 Other assets, net $ 3,720.2 21.4 $ 3,741.6 Liabilities: Deferred revenue $ 942.2 5.6 $ 947.8 Current liabilities of discontinued operations $ 1,587.7 26.7 $ 1,614.4 Other accrued and current liabilities $ 2,240.0 1.2 $ 2,241.2 Long-term liabilities of discontinued operations $ 9,967.6 39.1 $ 10,006.7 Other long-term liabilities $ 2,247.0 2.7 $ 2,249.7 Equity: Accumulated deficit (a) $ (6,217.6 ) 320.1 $ (5,897.5 ) Noncontrolling interests $ (412.0 ) 4.4 $ (407.6 ) _______________ (a) The ASU 2014-09 adjustment amounts include the impact of our share of the VodafoneZiggo JV ’s adjustment to its owners’ equity. The impact of our adoption of ASU 2014-09 on our condensed consolidated balance sheet as of June 30, 2018 was not materially different from the impacts set forth in the above January 1, 2018 summary balance sheet information. Similarly, the adoption of ASU 2014-09 did not have a material impact on our condensed consolidated statement of operations for the three and six months ended June 30, 2018 . ASU 2017-07 In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of the Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ( ASU 2017-07 ), which changes the presentation of periodic benefit cost components. Under ASU 2017-07 , we continue to present the service component of our net benefit cost as a component of operating income but present the other components of our net benefit cost, which can include credits, within non-operating income (expense) in our consolidated statements of operations. We adopted ASU 2017-07 on January 1, 2018 on a retrospective basis, which resulted in the reclassification of credits from SG&A expenses to other income, net, of $9.2 million for the six months ended June 30, 2017. ASU 2016-01 In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities ( ASU 2016-01 ), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 primarily impacts our accounting for certain equity investments that were previously accounted for under the cost method. Under ASU 2016-01 , these investments, which do not have readily determinable fair values, are accounted for at cost minus impairment, adjusted for any observable price changes of similar investments of the same issuer. We adopted the amendments of ASU 2016-01 related to equity securities without readily determinable fair values on January 1, 2018 on a prospective basis. ASU 2016-18 In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ( ASU 2016-18 ), which requires the change in restricted cash to be included together with the change in cash and cash equivalents in our consolidated statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 on a retrospective basis. Recent Accounting Pronouncements ASU 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases ( ASU 2016-02 ), which, for most leases, will result in lessees recognizing right-of-use assets and lease liabilities on the balance sheet and additional disclosures. ASU 2016-02 , as amended by ASU No. 2018-11, Targeted Improvements , requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using one of two modified retrospective approaches. A number of optional practical expedients may be applied in transition. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We will adopt ASU 2016-02 on January 1, 2019 by recording the cumulative effect of adoption to our accumulated deficit. Although we are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements, the main impact of the adoption of this standard will be the recognition of right-of-use assets and lease liabilities in our consolidated balance sheet for those leases classified as operating leases under current U.S. GAAP . We do not intend to recognize right-of-use assets or lease liabilities for leases with a term of 12 months or less, as permitted by the short-term lease practical expedient in the standard. We also do not plan to apply the practical expedient that permits a lessee to account for lease and non-lease components in a contract as a single lease component and, accordingly, we will continue to account for these components separately. In transition, we plan to apply the practical expedients that permit us not to reassess (i) whether expired or existing contracts contain a lease under the new standard, (ii) the lease classification for expired or existing leases or (iii) whether previously-capitalized initial direct costs would qualify for capitalization under the new standard. In addition, we do not intend to use hindsight during transition. For a summary of our undiscounted future minimum lease payments under non-cancellable operating leases as of June 30, 2018 , see note 15

Revenue Recognition and Related

Revenue Recognition and Related Costs	6 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition and Related Costs	Revenue Recognition and Related Costs Policies Our revenue recognition and certain other accounting policies, as revised to reflect the impacts of our adoption of ASU 2014-09 , are set forth below. Service Revenue — Cable Networks. We recognize revenue from the provision of video, broadband internet and fixed-line telephony services over our cable network to customers in the periods the related services are provided, with the exception of revenue recognized pursuant to certain contracts that contain promotional discounts, as described below. Installation fees related to services provided over our cable network are generally deferred and recognized as revenue over the contractual period, or longer if the upfront fee results in a material renewal right. Sale of Multiple Products and Services. We sell video, broadband internet, fixed-line telephony and, in most of our markets, mobile services to our customers in bundled packages at a rate lower than if the customer purchased each product on a standalone basis. Revenue from bundled packages generally is allocated proportionally to the individual products or services based on the relative standalone selling price for each respective product or service. Mobile Revenue — General. Consideration from mobile contracts is allocated to the airtime service component and the handset component based on the relative standalone selling prices of each component. In markets where we offer handsets and airtime services in separate contracts entered into at the same time, we account for these contracts as a single contract. Mobile Revenue — Airtime Services. We recognize revenue from mobile services in the periods in which the related services are provided. Revenue from pre-pay customers is deferred prior to the commencement of services and recognized as the services are rendered or usage rights expire. Mobile Revenue — Handset Revenue. Revenue from the sale of handsets is recognized at the point in which the goods have been transferred to the customer. Some of our mobile handset contracts that permit the customer to take control of the handset upfront and pay for the handset in installments over a contractual period may contain a significant financing component. For contracts with terms of one year or more, we recognize any significant financing component as revenue over the contractual period using the effective interest method. We do not record the effect of a significant financing component if the contractual period is less than one year. B2B Revenue. We defer upfront installation and certain nonrecurring fees received on B2B contracts where we maintain ownership of the installed equipment. The deferred fees are amortized into revenue on a straight-line basis, generally over the longer of the term of the arrangement or the expected period of performance. Contract Costs. Incremental costs to obtain a contract with a customer, such as incremental sales commissions, are generally recognized as assets and amortized to SG&A expenses over the applicable period benefited, which generally is the contract life. If, however, the amortization period is less than one year, we expense such costs in the period incurred. Contract fulfillment costs, such as porting costs, are recognized as assets and amortized to other operating costs over the applicable period benefited, which is generally the substantive contract term for the related service contract. Promotional Discounts. For subscriber promotions, such as discounted or free services during an introductory period, revenue is recognized uniformly over the contractual period if the contract has substantive termination penalties. If a contract does not have substantive termination penalties, revenue is recognized only to the extent of the discounted monthly fees charged to the subscriber, if any. Subscriber Advance Payments. Payments received in advance for the services we provide are deferred and recognized as revenue when the associated services are provided. Sales, Use and Other Value-Added Taxes. Revenue is recorded net of applicable sales, use and other value-added taxes. For a disaggregation of our revenue by major category and by reportable and geographic segment, see note 16 . Contract Balances The timing of revenue recognition may differ from the timing of invoicing our customers. We record a trade receivable when we have transferred goods or services to a customer but have not yet received payment. Our trade receivables are reported net of an allowance for doubtful accounts. Such allowance aggregated $57.0 million and $89.5 million at June 30, 2018 and January 1, 2018, respectively. If we transfer goods or services to a customer but do not have an unconditional right to payment, we record a contract asset. Contract assets typically arise from the uniform recognition of introductory promotional discounts over the contract period and accrued revenue for handset sales. Our contract assets were $27.7 million and $26.1 million as of June 30, 2018 and January 1, 2018, respectively. The current and long-term portions of our contract asset balance at June 30, 2018 are included within other current assets and other assets, net, respectively, in our condensed consolidated balance sheet. We record deferred revenue when we receive payment prior to transferring goods or services to a customer. We primarily defer revenue for (i) installation and other upfront services and (ii) other services that are invoiced prior to when services are provided. Our deferred revenue balances were $889.2 million and $1,005.2 million as of June 30, 2018 and January 1, 2018, respectively. The decrease in deferred revenue for the six months ended June 30, 2018 is primarily due to $801.8 million of revenue recognized that was included in our deferred revenue balance at January 1, 2018, partially offset by advanced billings in certain markets. The current and long-term portions of our deferred revenue balance at June 30, 2018 are included within deferred revenue and other long-term liabilities, respectively, in our condensed consolidated balance sheet. Contract Costs Our aggregate assets associated with incremental costs to obtain and fulfill our contracts were $68.4 million and $68.1 million at June 30, 2018 and January 1, 2018, respectively. The current and long-term portions of our assets related to contract costs at June 30, 2018 are included within other current assets and other assets, net, respectively, in our condensed consolidated balance sheet. We amortized $28.5 million and $51.3 million to operating costs and expenses during the three and six months ended June 30, 2018 , respectively, related to these assets. Unsatisfied Performance Obligations A large portion of our revenue is derived from customers who are not subject to contracts. Revenue from customers who are subject to contracts is generally recognized over the term of such contracts, which is typically 12 months for our residential service, one to three years for our mobile contracts and one to five years for our B2B

Acquisitions and Dispositions [Abstract]
Acquisitions and Dispositions	Acquisitions and Dispositions 2017 Acquisition On June 19, 2017 , Telenet acquired Coditel Brabant sprl, operating under the SFR brand ( SFR BeLux ), for a cash and debt free purchase price of €369.0 million ( $410.3 million at the applicable rates) (the SFR BeLux Acquisition ) after post-closing adjustments. SFR BeLux provides cable and mobile services to households and businesses in Belgium and Luxembourg. Pending and Completed Dispositions Vodafone Disposal Group On May 9, 2018, we reached an agreement (the Vodafone Agreement ) to sell our operations in Germany, Romania, Hungary and the Czech Republic to Vodafone Group plc ( Vodafone ). The cash proceeds that we receive from the transaction will be calculated on the basis of the agreed enterprise value adjusted for the net debt and working capital of such businesses as of the closing date of the transaction, as well as other post-closing adjustments. Based on the net debt and working capital of such businesses as of December 31, 2017, the cash proceeds would be approximately €10.6 billion ( $12.4 billion ). The operations of Germany, Romania, Hungary and the Czech Republic are collectively referred to herein as the “ Vodafone Disposal Group .” Closing of the transaction is subject to various conditions, including regulatory approval, which is not expected until mid-2019. The Vodafone Agreement contains certain termination rights for both our company and Vodafone , including if closing has not occurred by November 9, 2019, or May 9, 2020 in certain limited circumstances. If the Vodafone Agreement terminates because the condition to obtain antitrust approval is not met, Vodafone has agreed to pay us a compensatory payment of €250.0 million ( $291.9 million ). Pursuant to the Vodafone Agreement , our company will retain all cash generated from the Vodafone Disposal Group through the closing of the transaction. In connection with the sale of the Vodafone Disposal Group , we have agreed to provide certain transitional services for a period of up to four years . These services principally comprise network and information technology-related functions. The annual charges will depend on the actual level of services required by Vodafone . UPC Austria On July 31, 2018, we completed the sale of our Austrian operations, “ UPC Austria ,” to a third party for an enterprise value of €1.9 billion ( $2.2 billion at the transaction date). After considering debt, working capital and minority interest adjustments, we received net cash proceeds of €1.8 billion ( $2.1 billion at the transaction date). A portion of the net proceeds were used to repay or redeem an aggregate $1.5 billion (equivalent based on the applicable June 30, 2018 exchange rates) principal amount of our outstanding debt, including (i) the repayment of $913.8 million (equivalent) principal amount under the UPC Holding Bank Facility, (ii) the redemption of $70.1 million (equivalent) principal amount of the UPCB SPE Notes and (iii) the redemption of $519.9 million (equivalent) principal amount of the VM Notes. The remaining net proceeds from the sale of UPC Austria are expected to be used for general corporate purposes, including an additional $500.0 million of share repurchases, as further described in note 11 . In connection with the sale of UPC Austria , we have agreed to provide certain transitional services for a period of up to four years . These services principally comprise network and information technology-related functions. The annual charges will depend on the actual level of services required by the purchaser. Liberty Global will also allow the use of the UPC brand for a transitional period of up to three years as part of the transaction. Split-off Transaction Prior to December 29, 2017, our share capital included (i) Liberty Global Class A, Class B and Class C ordinary shares (collectively, Liberty Global Share s ) and (ii) LiLAC Class A, Class B and Class C (collectively, LiLAC Share s ). On December 29, 2017, in order to effect the split-off of the LiLAC Group (the Split-off Transaction ), we distributed 100% of the common shares (the Distribution ) of Liberty Latin America Ltd. ( Liberty Latin America ) to the holders of our then outstanding LiLAC Share s. Just prior to the completion of the Split-off Transaction , all of the businesses, assets and liabilities of the LiLAC Group were transferred to Liberty Latin America , which was then a wholly-owned subsidiary of Liberty Global . Following the Distribution , the LiLAC Share s were redesignated as deferred shares (which had virtually no economic rights) and Liberty Latin America became an independent publicly-traded company that is no longer consolidated by Liberty Global . No gain or loss was recognized in connection with the Split-off Transaction . In connection with the Split-off Transaction , we entered into several agreements that govern certain transactions and other matters between our company and Liberty Latin America (the Split-off Agreements ). During the six months ended June 30, 2018 , the impacts of the Split-off Agreements and other normal recurring transactions between our company and Liberty Latin America were not material. Presentation of Discontinued Operations Effective with the signing of the Vodafone Agreement , we began presenting the Vodafone Disposal Group as discontinued operations and, accordingly, we no longer depreciate or amortize the long-lived assets of such group. From December 22, 2017, the date we reached an agreement to sell UPC Austria , through the signing of the Vodafone Agreement , we accounted for UPC Austria as held for sale but did not present such entity as a discontinued operation as this disposal was not considered to be a strategic shift that would have a major effect on our operations and financial results. We ceased to depreciate or amortize the long-lived assets of UPC Austria on December 22, 2017. Effective with the signing of the Vodafone Agreement and in consideration of the additional disposals contemplated therein, we began presenting UPC Austria as a discontinued operation. Accordingly, UPC Austria and the Vodafone Disposal Group are presented as discontinued operations in our condensed consolidated balance sheets, statements of operations and cash flows for all periods presented. Our operations in Romania, Hungary and the Czech Republic are held through UPC Holding , as was UPC Austria prior to its sale on July 31, 2018. No debt, interest or derivative instruments of the UPC Holding borrowing group, other than amounts that are direct obligations of the entities to be disposed, has been allocated to discontinued operations. Conversely, all of Unitymedia’s debt, interest and derivative instruments are included in discontinued operations as they are direct obligations of entities within the Vodafone Disposal Group . As discussed above, a portion of the proceeds from the disposition of UPC Austria was used to pay down the debt of the UPC Holding borrowing group. In addition, we expect that a portion of the proceeds from the disposition of the Vodafone Disposal Group will be used to pay down the debt of the UPC Holding borrowing group. In addition, the entities comprising the LiLAC Group are reflected as discontinued operations in our condensed consolidated statements of operations and cash flows for the three and six months ended June 30, 2017. The carrying amounts of the major classes of assets and liabilities of UPC Austria and the Vodafone Disposal Group as of June 30, 2018 are summarized below: UPC Austria Vodafone Disposal Group Total in millions Assets: Current assets other than cash $ 40.9 $ 384.3 $ 425.2 Property and equipment, net 479.6 5,245.8 5,725.4 Goodwill 706.0 4,041.0 4,747.0 Other assets, net 3.2 458.2 461.4 Total assets $ 1,229.7 $ 10,129.3 $ 11,359.0 Liabilities: Current portion of debt and capital lease obligations $ 0.8 $ 602.3 $ 603.1 Other accrued and current liabilities 82.8 1,187.2 1,270.0 Long-term debt and capital lease obligations 1.3 9,155.7 9,157.0 Other long-term liabilities 85.1 883.3 968.4 Total liabilities $ 170.0 $ 11,828.5 $ 11,998.5 The carrying amounts of the major classes of assets and liabilities of UPC Austria and the Vodafone Disposal Group as of December 31, 2017 are summarized below: UPC Austria Vodafone Disposal Group Total in millions Assets: Current assets other than cash $ 29.2 $ 238.9 $ 268.1 Property and equipment, net 451.9 5,290.1 5,742.0 Goodwill 732.2 4,181.0 4,913.2 Other assets, net 3.2 482.7 485.9 Total assets $ 1,216.5 $ 10,192.7 $ 11,409.2 Liabilities: Current portion of debt and capital lease obligations $ 0.8 $ 486.9 $ 487.7 Other accrued and current liabilities 77.7 1,022.3 1,100.0 Long-term debt and capital lease obligations 1.5 9,026.1 9,027.6 Other long-term liabilities 76.3 863.7 940.0 Total liabilities $ 156.3 $ 11,399.0 $ 11,555.3 The operating results of UPC Austria , the Vodafone Disposal Group and the LiLAC Group for the three and six months ended June 30, 2018 and 2017 are summarized in the following tables.

( Multimedia ), the third-largest cable operator in Poland. On October 18, 2017, the Polish regulator issued a statement of objection against the proposed transaction on the basis that such transaction could restrict competition in a number of cities across the country. On March 23, 2018, UPC Poland withdrew its application for regulatory clearance to acquire Multimedia after failing to agree to revised commercial terms with the sellers that take into account current regulatory and market conditions. In addition, the agreement to acquire Multimedia

(b) Amounts include a related-party euro-denominated note receivable (the VodafoneZiggo JV Receivable ) with a principal amount of $1,050.9 million and $1,081.9 million , respectively, due from a subsidiary of the VodafoneZiggo JV (as defined below) to a subsidiary of Liberty Global . The VodafoneZiggo JV Receivable bears interest at 5.55% and requires €100.0 million ( $116.8 million ) of principal to be paid annually through December 31, 2019, with the remaining principal due on January 16, 2027. The accrued interest on the VodafoneZiggo JV Receivable will be payable in a manner mutually agreed upon by Liberty Global and the VodafoneZiggo JV . During the six months ended June 30, 2018 , interest accrued on the VodafoneZiggo JV Receivable was $30.2 million , all of which has been cash settled. (c) As a result of the January 1, 2018 adoption of ASU 2016-01 , all of our cost investments have been reclassified to fair value investments. For information regarding the impact of the adoption of ASU 2014-09 on our accumulated deficit and our investment in the VodafoneZiggo JV , see note 2 . Equity Method Investments The following table sets forth the details of our share of losses of affiliates, net: Three months ended June 30, Six months ended 2018 2017 2018 2017 in millions VodafoneZiggo JV (a) $ (63.2 ) $ 6.5 $ (90.0 ) $ 5.2 Other (19.1 ) (10.1 ) (28.8 ) (24.5 ) Total $ (82.3 ) $ (3.6 ) $ (118.8 ) $ (19.3 ) _______________ (a) Amounts include the net effect of (i) 100% of the interest income earned on the VodafoneZiggo JV Receivable , (ii) 100% of the share-based compensation expense associated with Liberty Global awards held by VodafoneZiggo JV employees who were formerly employees of Liberty Global , as these awards remain our responsibility, and (iii) our 50% share of the remaining results of operations of the VodafoneZiggo JV . VodafoneZiggo JV . On December 31, 2016, one of our wholly-owned subsidiaries contributed VodafoneZiggo Holding B.V. and its subsidiaries ( VodafoneZiggo Holding ) to VodafoneZiggo Group Holding B.V., an entity that was formed as a 50 : 50 joint venture (the VodafoneZiggo JV ) between Vodafone and Liberty Global (the VodafoneZiggo JV Transaction ). On January 4, 2017, in connection with the completion of the VodafoneZiggo JV Transaction , we received cash of €2.2 billion ( $2.4 billion at the transaction date) comprising (i) a distribution reflecting our 50% share of the €2.8 billion ( $2.9 billion at the transaction date) of net proceeds from the various debt financing arrangements entered into by certain subsidiaries of VodafoneZiggo Holding during the third quarter of 2016 and (ii) an equalization payment from Vodafone of €802.9 million ( $840.8 million at the transaction date) that was subject to post-closing adjustments. During the second quarter of 2017, the equalization amount was finalized, resulting in the receipt of an additional €3.9 million ( $4.5 million at the transaction date) from Vodafone . During the first quarter of 2017, we paid $162.6 million of VAT on behalf of the VodafoneZiggo JV associated with the termination of a services agreement with Ziggo Group Holding B.V. that was in effect prior to the closing of the VodafoneZiggo JV Transaction . This advance was repaid during the first quarter of 2017. In addition, during the second quarters of 2018 and 2017, we received dividend distributions from the VodafoneZiggo JV of $116.6 million and $87.3 million , respectively, which were accounted for as returns on capital for purposes of our condensed consolidated statements of cash flows. Pursuant to an agreement entered into in connection with the formation of the VodafoneZiggo JV (the Framework Agreement ), Liberty Global provides certain services to the VodafoneZiggo JV on a transitional or ongoing basis (collectively, the JV Services ). The JV Services provided by Liberty Global consist primarily of (i) technology and other services and (ii) capital-related expenditures for assets that will be used by, or will otherwise benefit, the VodafoneZiggo JV . Liberty Global charges both fixed and usage-based fees to the VodafoneZiggo JV for the JV Services provided during the term of the Framework Agreement . We recorded revenue from the VodafoneZiggo JV of $53.8 million and $31.8 million during the three months ended June 30, 2018 and 2017 , respectively, and $88.3 million and $63.3 million during the six months ended June 30, 2018 and 2017 , respectively. These amounts include revenue from (a) the JV Services and (b) during the 2018 periods, sales of customer premises equipment at a mark-up. During the six months ended June 30, 2018 and 2017 , we transferred certain assets to the VodafoneZiggo JV that we purchased on its behalf with an aggregate cost of $30.3 million and $107.8 million , respectively. At June 30, 2018 and December 31, 2017 , $46.8 million and $ 33.3 million , respectively, were due from the VodafoneZiggo JV , primarily related to the aforementioned transactions. Amounts due from the VodafoneZiggo JV , which are periodically cash settled, are included in other current assets in our condensed consolidated balance sheet. The VodafoneZiggo JV is experiencing significant competition. In particular, the mobile operations of the VodafoneZiggo JV continue to experience competitive pressure on pricing, characterized by aggressive promotion campaigns, heavy marketing efforts and increasing or unlimited data bundles. In light of this competition, as well as regulatory and economic factors, we could conclude in future periods that our investment in the VodafoneZiggo JV is impaired or management of the VodafoneZiggo JV could conclude that an impairment of the VodafoneZiggo JV goodwill and, to a lesser extent, long-lived assets, is required. Any such impairment of the VodafoneZiggo JV’s goodwill or our investment in the VodafoneZiggo JV would be reflected as a component of share of results of affiliates, net, in our condensed consolidated statement of operations. Our share of any such impairment charges could be significant. The summarized results of operations of the VodafoneZiggo JV are set forth below: Three months ended Six months ended June 30, June 30, 2018 2017 2018 2017 in millions Revenue $ 1,114.5 $ 1,081.3 $ 2,296.1 $ 2,165.2 Loss before income taxes $ (201.2 ) $ (25.8 ) $ (319.8 ) $ (69.1 ) Net loss $ (150.8 ) $ (18.3 ) $ (238.1 ) $ (48.6 )

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In general, we seek to enter into derivative instruments to protect against (i) increases in the interest rates on our variable-rate debt, (ii) foreign currency movements, particularly with respect to borrowings that are denominated in a currency other than the functional currency of the borrowing entity, and (iii) decreases in the market prices of certain publicly traded securities that we own. In this regard, through our subsidiaries, we have entered into various derivative instruments to manage interest rate exposure and foreign currency exposure primarily with respect to the U.S. dollar ( $ ), the euro ( € ), the British pound sterling ( £ ), the Swiss franc ( CHF ), the Czech koruna ( CZK ), the Hungarian forint ( HUF ), the Polish zloty ( PLN ) and the Romanian lei ( RON ). With the exception of a limited number of our foreign currency forward contracts, we do not apply hedge accounting to our derivative instruments. Accordingly, changes in the fair values of most of our derivative instruments are recorded in realized and unrealized gains or losses on derivative instruments, net, in our condensed consolidated statements of operations. The following table provides details of the fair values of our derivative instrument assets and liabilities: June 30, 2018 December 31, 2017 Current (a) Long-term (a) Total Current (a) Long-term (a) Total in millions Assets: Cross-currency and interest rate derivative contracts (b) $ 371.6 $ 1,344.1 $ 1,715.7 $ 477.0 $ 1,071.9 $ 1,548.9 Equity-related derivative instruments (c) — 491.9 491.9 — 560.9 560.9 Foreign currency forward and option contracts 13.6 — 13.6 17.0 0.1 17.1 Other 0.1 — 0.1 0.4 0.4 0.8 Total $ 385.3 $ 1,836.0 $ 2,221.3 $ 494.4 $ 1,633.3 $ 2,127.7 Liabilities: Cross-currency and interest rate derivative contracts (b) $ 386.5 $ 1,254.1 $ 1,640.6 $ 210.2 $ 1,557.7 $ 1,767.9 Equity-related derivative instruments (c) 1.7 — 1.7 5.4 — 5.4 Foreign currency forward and option contracts 4.5 — 4.5 7.7 0.2 7.9 Other — 0.1 0.1 — — — Total $ 392.7 $ 1,254.2 $ 1,646.9 $ 223.3 $ 1,557.9 $ 1,781.2 _______________ (a) Our current derivative liabilities, long-term derivative assets and long-term derivative liabilities are included in other current and accrued liabilities, other assets, net, and other long-term liabilities, respectively, in our condensed consolidated balance sheets. (b) We consider credit risk relating to our and our counterparties’ nonperformance in the fair value assessment of our derivative instruments. In all cases, the adjustments take into account offsetting liability or asset positions within each of our subsidiary borrowing groups (as defined and described in note 9 ). The changes in the credit risk valuation adjustments associated with our cross-currency and interest rate derivative contracts resulted in a net gain (loss) of ( $65.6 million ) and $59.6 million during the three months ended June 30, 2018 and 2017 , respectively, and a net gain (loss) of ( $27.9 million ) and $109.0 million during the six months ended June 30, 2018 and 2017 , respectively. These amounts are included in realized and unrealized gains (losses) on derivative instruments, net, in our condensed consolidated statements of operations. For further information regarding our fair value measurements, see note 7 . (c) Our equity-related derivative instruments primarily include the fair value of (i) the share collar (the ITV Collar ) with respect to ITV shares held by our company, (ii) the prepaid forward transaction (the Lionsgate Forward ) with respect to 1.25 million of our voting and 1.25 million of our non-voting Lionsgate shares and (iii) at December 31, 2017, the share collar (the Sumitomo Collar ) with respect to a portion of the shares of Sumitomo held by our company. On May 22, 2018, we settled the final tranche of the Sumitomo Collar and related borrowings with a portion of the existing Sumitomo shares held by our company. The aggregate market value of these shares on the transaction date was $159.3 million .The fair values of the ITV Collar and the Lionsgate Forward do not include credit risk valuation adjustments as we assume that any losses incurred by our company in the event of nonperformance by the respective counterparty would be, subject to relevant insolvency laws, fully offset against amounts we owe to such counterparty pursuant to the related secured borrowing arrangements. The details of our realized and unrealized gains (losses) on derivative instruments, net, are as follows: Three months ended Six months ended June 30, June 30, 2018 2017 2018 2017 in millions Cross-currency and interest rate derivative contracts $ 870.1 $ (502.3 ) $ 508.2 $ (659.1 ) Equity-related derivative instruments: ITV Collar (183.6 ) 163.4 (60.0 ) 110.2 Lionsgate Forward 3.4 (2.5 ) 12.4 (2.0 ) Sumitomo Collar (23.2 ) 2.2 (11.8 ) (21.3 ) Other 1.0 0.4 2.2 (5.4 ) Total equity-related derivative instruments (202.4 ) 163.5 (57.2 ) 81.5 Foreign currency forward and option contracts 8.3 (12.9 ) 13.9 (19.0 ) Other (0.5 ) — (0.7 ) 0.5 Total $ 675.5 $ (351.7 ) $ 464.2 $ (596.1 ) The net cash received or paid related to our derivative instruments is classified as an operating, investing or financing activity in our condensed consolidated statements of cash flows based on the objective of the derivative instrument and the classification of the applicable underlying cash flows. For foreign currency forward contracts that are used to hedge capital expenditures, the net cash received or paid is classified as an adjustment to capital expenditures in our condensed consolidated statements of cash flows. For derivative contracts that are terminated prior to maturity, the cash paid or received upon termination that relates to future periods is classified as a financing activity. The following table sets forth the classification of the net cash inflows (outflows) of our derivative instruments: Six months ended June 30, 2018 2017 in millions Operating activities $ 246.1 $ 89.5 Investing activities — (0.5 ) Financing activities 10.2 (139.0 ) Total $ 256.3 $ (50.0 ) Counterparty Credit Risk We are exposed to the risk that the counterparties to the derivative instruments of our subsidiary borrowing groups will default on their obligations to us. We manage these credit risks through the evaluation and monitoring of the creditworthiness of, and concentration of risk with, the respective counterparties. In this regard, credit risk associated with our derivative instruments is spread across a relatively broad counterparty base of banks and financial institutions. With the exception of a limited number of instances where we have required a counterparty to post collateral, neither party has posted collateral under the derivative instruments of our subsidiary borrowing groups. At June 30, 2018 , our exposure to counterparty credit risk included derivative assets with an aggregate fair value of $456.1 million . Details of our Derivative Instruments Cross-currency Derivative Contracts As noted above, we are exposed to foreign currency exchange rate risk in situations where our debt is denominated in a currency other than the functional currency of the operations whose cash flows support our ability to repay or refinance such debt. Although we generally seek to match the denomination of our subsidiaries’ borrowings with the functional currency of the operations that are supporting the respective borrowings, market conditions or other factors may cause us to enter into borrowing arrangements that are not denominated in the functional currency of the underlying operations (unmatched debt). Our policy is generally to provide for an economic hedge against foreign currency exchange rate movements by using derivative instruments to synthetically convert unmatched debt into the applicable underlying currency. At June 30, 2018 , substantially all of our debt was either directly or synthetically matched to the applicable functional currencies of the underlying operations. The following table sets forth the total notional amounts and the related weighted average remaining contractual lives of our cross-currency swap contracts at June 30, 2018 : Borrowing group Notional amount due from counterparty Notional amount due to counterparty Weighted average remaining life in millions in years Virgin Media $ 400.0 € 339.6 4.6 $ 8,933.0 £ 5,844.3 (a) (b) 5.2 £ 2,396.1 $ 3,450.0 (a) 6.5 UPC Holding $ 2,765.0 € 2,276.7 6.3 $ 1,200.0 CHF 1,107.5 (b) 6.7 € 2,521.2 CHF 2,901.0 (b) 5.5 € 418.5 CZK 11,521.8 2.0 € 488.0 HUF 138,437.5 3.5 € 851.6 PLN 3,604.5 3.2 € 225.9 RON 650.0 3.6 Telenet $ 3,195.0 € 2,834.1 (b) 6.9 € 1,431.2 $ 1,600.0 (a) 7.0 _______________ (a) Includes certain derivative instruments that do not involve the exchange of notional amounts at the inception and maturity of the instruments. Accordingly, the only cash flows associated with these derivative instruments are coupon-related payments and receipts. At June 30, 2018 , the total U.S. dollar equivalents of the notional amount of these derivative instruments was $5.3 billion . (b) Includes certain derivative instruments that are “forward-starting,” such that the initial exchange occurs at a date subsequent to June 30, 2018 . These instruments are typically entered into in order to extend existing hedges without the need to amend existing contracts. Interest Rate Swap Contracts As noted above, we enter into interest rate swaps to protect against increases in the interest rates on our variable-rate debt. The following table sets forth the total U.S. dollar equivalents of the notional amounts and the related weighted average remaining contractual lives of our interest rate swap contracts at June 30, 2018 : Borrowing group pays fixed rate (a) Borrowing group receives fixed rate Borrowing group Notional amount Weighted average remaining life Notional amount Weighted average remaining life in millions in years in millions in years Virgin Media $ 18,625.7 3.6 $ 11,789.1 5.7 UPC Holding $ 5,766.6 5.1 $ 3,408.3 7.3 Telenet $ 3,686.4 5.5 $ 1,666.3 5.2 _______________ (a) Includes forward-starting derivative instruments. Interest Rate Swap Options We have entered into various interest rate swap options ( swaption s ), which give us the right, but not the obligation, to enter into certain interest rate swap contracts at set dates in the future, with each such contract having a life of no more than three years. At the transaction date, the strike rate of each of these contracts was above the corresponding market rate. The following table sets forth certain information regarding our swaption s at June 30, 2018 : Borrowing group Notional amount Underlying swap currency Weighted average option expiration period (a) Weighted average strike rate (b) in millions in years Virgin Media $ 6,275.6 £ 1.4 2.47% $ 601.1 € 1.4 2.08% UPC Holding $ 1,328.3 CHF 0.6 1.22% ______________ (a) Represents the weighted average period until the date on which we have the option to enter into the interest rate swap contracts. (b) Represents the weighted average interest rate that we would pay if we exercised our option to enter into the interest rate swap contracts. Basis Swaps Our basis swaps involve the exchange of attributes used to calculate our floating interest rates, including (i) the benchmark rate, (ii) the underlying currency and/or (iii) the borrowing period. We typically enter into these swaps to optimize our interest rate profile based on our current evaluations of yield curves, our risk management policies and other factors. The following table sets forth the total U.S. dollar equivalents of the notional amounts and related weighted average remaining contractual lives of our basis swap contracts at June 30, 2018 : Borrowing group Notional amount due from counterparty Weighted average remaining life in millions in years Virgin Media $ 4,587.5 0.5 UPC Holding $ 1,975.0 0.5 Telenet $ 1,600.0 0.5 Interest Rate Caps and Collars We enter into interest rate cap and collar agreements that lock in a maximum interest rate if variable rates rise, but also allow our company to benefit, to a limited extent in the case of collars, from declines in market rates. At June 30, 2018 , the total U.S. dollar equivalents of the notional amounts of our interest rate caps and collars were $164.9 million and $662.7 million , respectively. Impact of Derivative Instruments on Borrowing Costs The impact of the derivative instruments that mitigate our foreign currency and interest rate risk, as described above, on our borrowing costs is as follows: Borrowing group Decrease to borrowing costs at June 30, 2018 (a) Virgin Media (0.32 )% UPC Holding (0.02 )% Telenet (0.44 )% Total decrease to borrowing costs (0.27 )% _______________ (a) Represents the effect of derivative instruments in effect at June 30, 2018 and does not include forward-starting derivative instruments or swaption s. Foreign Currency Forwards and Options Certain of our subsidiaries enter into foreign currency forward and option contracts with respect to non-functional currency exposure. As of June 30, 2018 , the total U.S. dollar equivalents of the notional amount of foreign currency forward and option contracts was $482.4 million

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We use the fair value method to account for (i) certain of our investments, (ii) our derivative instruments, (iii) certain instruments that we classify as debt and (iv) the borrowed shares of Sumitomo pursuant to a securities lending arrangement (the Sumitomo Share Loan ). The reported fair values of these investments and instruments as of June 30, 2018 likely will not represent the value that will be paid or received upon the ultimate settlement or disposition of these assets and liabilities. U.S. GAAP provides for a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. We record transfers of assets or liabilities into or out of Levels 1, 2 or 3 at the beginning of the quarter during which the transfer occurred. We incorporate a credit risk valuation adjustment in our fair value measurements to estimate the impact of both our own nonperformance risk and the nonperformance risk of our counterparties. Our credit risk valuation adjustments with respect to our cross-currency and interest rate swaps are quantified and further explained in note 6 . Fair value measurements are also used in connection with nonrecurring valuations performed in connection with acquisition accounting and impairment assessments. The nonrecurring valuations associated with acquisition accounting primarily include the valuation of reporting units, customer relationship and other intangible assets and property and equipment. Unless a reporting unit has a readily determinable fair value, the valuation of reporting units is based at least in part on discounted cash flow analyses. With the exception of certain inputs for our weighted average cost of capital and discount rate calculations that are derived from pricing services, the inputs used in our discounted cash flow analyses, such as forecasts of future cash flows, are based on our assumptions. The valuation of customer relationships is primarily based on an excess earnings methodology, which is a form of a discounted cash flow analysis. The excess earnings methodology requires us to estimate the specific cash flows expected from the customer relationship, considering such factors as estimated customer life, the revenue expected to be generated over the life of the customer relationship, contributory asset charges and other factors. Tangible assets are typically valued using a replacement or reproduction cost approach, considering factors such as current prices of the same or similar equipment, the age of the equipment and economic obsolescence. Most of our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy. During the six months ended June 30, 2018 and 2017 , we did not perform significant nonrecurring fair value measurements. For additional information concerning our fair value measurements, see note 8 to the consolidated financial statements included in our 10-K . A summary of our assets and liabilities that are measured at fair value on a recurring basis is as follows: Fair value measurements at June 30, 2018 using: Description June 30, Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) in millions Assets: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,715.7 $ — $ 1,715.0 $ 0.7 Equity-related derivative instruments 491.9 — — 491.9 Foreign currency forward and option contracts 13.6 — 13.6 — Other 0.1 — 0.1 — Total derivative instruments 2,221.3 — 1,728.7 492.6 Investments 2,164.1 1,717.1 — 447.0 Total assets $ 4,385.4 $ 1,717.1 $ 1,728.7 $ 939.6 Liabilities: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,640.6 $ — $ 1,632.6 $ 8.0 Equity-related derivative instruments 1.7 — — 1.7 Foreign currency forward and option contracts 4.5 — 4.5 — Other 0.1 — 0.1 — Total derivative instruments 1,646.9 — 1,637.2 9.7 Debt 881.7 600.6 281.1 — Total liabilities $ 2,528.6 $ 600.6 $ 1,918.3 $ 9.7 Fair value measurements at December 31, 2017 using: Description December 31, 2017 Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) in millions Assets: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,548.9 $ — $ 1,548.7 $ 0.2 Equity-related derivative instruments 560.9 — — 560.9 Foreign currency forward and option contracts 17.1 — 17.1 — Other 0.8 — 0.8 — Total derivative instruments 2,127.7 — 1,566.6 561.1 Investments 2,315.3 1,908.7 — 406.6 Total assets $ 4,443.0 $ 1,908.7 $ 1,566.6 $ 967.7 Liabilities: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,767.9 $ — $ 1,764.5 $ 3.4 Equity-related derivative instruments 5.4 — — 5.4 Foreign currency forward and option contracts 7.9 — 7.9 — Total derivative instruments 1,781.2 — 1,772.4 8.8 Debt 926.6 621.7 304.9 — Total liabilities $ 2,707.8 $ 621.7 $ 2,077.3 $ 8.8 A reconciliation of the beginning and ending balances of our assets and liabilities measured at fair value on a recurring basis using significant unobservable, or Level 3, inputs is as follows: Investments Cross-currency and interest rate derivative contracts Equity-related derivative instruments Total in millions Balance of net assets (liabilities) at January 1, 2018 $ 406.6 $ (3.2 ) $ 555.5 $ 958.9 Gains (losses) included in earnings (loss) from continuing operations (a): Realized and unrealized losses on derivative instruments, net — (4.5 ) (57.2 ) (61.7 ) Realized and unrealized gains due to changes in fair values of certain investments and debt, net 4.4 — — 4.4 Impact of ASU 2016-01 31.9 — — 31.9 Additions 25.1 0.2 — 25.3 Dispositions (12.1 ) — — (12.1 ) Final settlement of Sumitomo Collar (b) — — (7.4 ) (7.4 ) Transfers out of Level 3 (2.0 ) — — (2.0 ) Foreign currency translation adjustments, dividends and other, net (6.9 ) 0.2 (0.7 ) (7.4 ) Balance of net assets (liabilities) at June 30, 2018 $ 447.0 $ (7.3 ) $ 490.2 $ 929.9 _______________ (a) Most of these net gains and losses relate to assets and liabilities that we continue to carry on our condensed consolidated balance sheet as of June 30, 2018 .

The interest rates presented represent stated rates and do not include the impact of derivative instruments, deferred financing costs, original issue premiums or discounts and commitment fees, all of which affect our overall cost of borrowing. Including the effects of derivative instruments, original issue premiums or discounts and commitment fees, but excluding the impact of deferred financing costs, our weighted average interest rate on our aggregate variable- and fixed-rate indebtedness was 3.98% at June 30, 2018 . For information regarding our derivative instruments, see note 6 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at June 30, 2018 without regard to covenant compliance calculations or other conditions precedent to borrowing. At June 30, 2018 , based on the most restrictive applicable leverage covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, and based on the most restrictive applicable leverage-based restricted payment tests, there were no restrictions on the respective subsidiary's ability to make loans or distributions from this availability to Liberty Global or its subsidiaries or other equity holders, except as shown in the table below. In the following table we present, based on the most restrictive applicable leverage covenants, leverage-based restricted payment tests and other limitations in effect for each borrowing group, (i) for each subsidiary where the ability to borrow is limited, the actual borrowing availability under the respective facility and (ii) for each subsidiary where the ability to make loans or distributions from this availability is limited, the amount that can be loaned or distributed to Liberty Global or its subsidiaries or other equity holders. The amounts presented below do not consider any actual or potential changes to our borrowing levels subsequent to June 30, 2018 and are based on the most restrictive applicable leverage-based restricted payment tests and covenant and other limitations in effect for each borrowing group at June 30, 2018, both before and after considering the impact of the completion of the June 30, 2018 compliance requirements. Limitation on availability June 30, 2018 Upon completion of relevant June 30, 2018 compliance reporting requirements Borrowing currency U.S. $ equivalent Borrowing currency U.S. $ equivalent in millions Limitation on availability to be borrowed under: VM Credit Facilities (e) £ 675.0 $ 890.6 £ 455.4 $ 600.9 (c) The estimated fair values of our debt instruments are generally determined using the average of applicable bid and ask prices (mostly Level 1 of the fair value hierarchy) or, when quoted market prices are unavailable or not considered indicative of fair value, discounted cash flow models (mostly Level 2 of the fair value hierarchy). The discount rates used in the cash flow models are based on the market interest rates and estimated credit spreads of the applicable entity, to the extent available, and other relevant factors. For additional information regarding fair value hierarchies, see note 7 . (d) As further described in note 4 , subsequent to June 30, 2018, we used a portion of the net proceeds from the sale of UPC Austria to repay or redeem certain debt of the UPC Holding and Virgin Media borrowing groups. (e) Unused borrowing capacity under the VM Credit Facilities relates to multi-currency revolving facilities with an aggregate maximum borrowing capacity equivalent to £675.0 million ( $890.6 million ). In February 2018, the VM Revolving Facility was amended and split into two revolving facilities. VM Revolving Facility A is a multi-currency revolving facility maturing on December 31, 2021 with a maximum borrowing capacity equivalent to £75.0 million ( $98.9 million ), and VM Revolving Facility B is a multi-currency revolving facility maturing on January 15, 2024 with a maximum borrowing capacity equivalent to £600.0 million ( $791.7 million ). All other terms from the previously existing VM Revolving Facility continue to apply to the new revolving facilities (f) Unused borrowing capacity under the Telenet Credit Facility comprises (i) €400.0 million ( $467.1 million ) under Telenet Facility AG, (ii) €25.0 million ( $29.2 million ) under the Telenet Overdraft Facility and (iii) €20.0 million ( $23.4 million ) under the Telenet Revolving Facility, each of which were undrawn at June 30, 2018 . (g) Represents amounts owed pursuant to interest-bearing vendor financing arrangements that are used to finance certain of our property and equipment additions and, to a lesser extent, certain of our operating expenses. These obligations are generally due within one year and include VAT that was paid on our behalf by the vendor. Repayments of vendor financing obligations are included in repayments and repurchases of debt and capital lease obligations in our condensed consolidated statements of cash flows. (h) The Sumitomo Share Loan is carried at fair value. For information regarding fair value hierarchies, see note 7 . (i) Represents amounts associated with certain derivative-related borrowing instruments, including $281.1 million and $304.9 million at June 30, 2018 and December 31, 2017 , respectively, carried at fair value. These instruments mature at various dates through January 2025. For information regarding fair value hierarchies, see note 7 . (j) Amounts include $131.0 million and $160.9 million at June 30, 2018 and December 31, 2017 , respectively, of debt collateralized by certain trade receivables of Virgin Media . (k) The U.S. dollar equivalents of our consolidated capital lease obligations are as follows: June 30, 2018 December 31, 2017 in millions Telenet $ 461.6 $ 456.1 UPC Holding 80.6 89.0 Virgin Media 73.5 79.1 Other subsidiaries 57.1 67.2 Total $ 672.8 $ 691.4 Refinancing Transactions - General Information At June 30, 2018 , most of our outstanding debt had been incurred by one of our three subsidiary “borrowing groups.” References to these borrowing groups, which comprise Virgin Media , UPC Holding and Telenet , include their respective restricted parent and subsidiary entities. Below we provide summary descriptions of any financing transactions completed during the first six months of 2018 . Unless otherwise noted, the terms and conditions of any new notes and/or credit facilities are largely consistent with those of existing notes and credit facilities of the corresponding borrowing group with regard to covenants, events of default and change of control provisions, among other items. For information regarding the general terms and conditions of our debt and capitalized terms not defined herein, see note 10 to the consolidated financial statements included in our 10-K . Virgin Media Financing Transaction In April 2018, Virgin Media Receivables Financing Notes II Designated Activity Company ( Virgin Media Receivables II Financing Company ), a third-party special purpose financing entity that is not consolidated by Virgin Media or Liberty Global, issued £300.0 million ( $395.8 million ) principal amount of 5.75% receivables financing notes due April 15, 2023. In June 2018, Virgin Media Receivables II Financing Company issued an additional £50.0 million ( $66.0 million ) principal amount of 5.75% receivables financing notes due April 15, 2023. These notes, together with the initial £300.0 million , are collectively referred to as the “ VM Receivables Financing II Notes .” The VM Receivables Financing II Notes are not the obligations of Virgin Media or Liberty Global. The net proceeds from the VM Receivables Financing II Notes are used to purchase certain vendor financed receivables of Virgin Media and its subsidiaries from various third parties. To the extent that the proceeds from the VM Receivables Financing II Notes exceed the amount of vendor financed receivables available to be purchased, the excess proceeds are used to fund an excess cash facility (the VM Financing Facility II ) under a new credit facility of Virgin Media . The VM Financing Facility II , together with the VM Financing Facility , which was created in connection with the issuance of the VM Receivables Financing Notes by Virgin Media Receivables Financing Company in 2016, are collectively referred to as the “ VM Financing Facilities .” At June 30, 2018, the principal amount outstanding under the VM Financing Facilities was £700.0 million ( $923.6 million ). Virgin Media Receivables Financing Company and Virgin Media Receivables II Financing Company can request the VM Financing Facilities be repaid by Virgin Media as additional vendor financed receivables become available for purchase. Telenet Refinancing Transactions In March 2018, Telenet used existing cash to prepay 10% of the €530.0 million ( $618.9 million ) original principal amount under Telenet Facility AB, together with accrued and unpaid interest and the related prepayment premiums, which was owed to Telenet Finance VI and, in turn, Telenet Finance VI used such proceeds to redeem 10% of the €530.0 million original principal amount of the Telenet Finance VI Notes. In connection with this transaction, Telenet recognized a loss on debt modification and extinguishment, net, of $2.6 million related to (i) the payment of $2.0 million of redemption premiums and (ii) the write-off of $0.6 million of unamortized deferred financing costs and discounts. In March 2018, commitments under Telenet Facility AL were increased by $300.0 million (the Telenet Facility AL Add-on ). The terms of the Telenet Facility AL Add-on are consistent with those of Telenet Facility AL . In April 2018, Telenet drew the full $300.0 million of the Telenet Facility AL Add-on and used the net proceeds, together with existing cash, to prepay in full the €250.0 million ( $291.9 million ) outstanding principal amount under Telenet Facility V , together with accrued and unpaid interest and the related prepayment premiums, which was owed to Telenet Finance V and, in turn, Telenet Finance V used such proceeds to redeem in full the €250.0 million outstanding principal amount of the Telenet Finance V Notes. In connection with this transaction, Telenet recognized a loss on debt modification and extinguishment, net, of $21.3 million related to (i) the payment of $17.3 million of redemption premiums and (ii) the write-off of $4.0 million of unamortized deferred financing costs and discounts. In May 2018, Telenet entered into (i) a $1,600.0 million term loan facility ( Telenet Facility AN ), which was issued at 99.875% of par, matures on August 15, 2026, bears interest at a rate of LIBOR + 2.25% and is subject to a LIBOR floor of 0.0% , and (ii) a €730.0 million ( $852.4 million ) term loan facility ( Telenet Facility AO ), which was issued at 99.875% of par, matures on December 15, 2027, bears interest at a rate of EURIBOR + 2.50% and is subject to a EURIBOR floor of 0.0% . The net proceeds from Telenet Facility AN and Telenet Facility AO , together with existing cash, were used to prepay in full (a) the $1,300.0 million outstanding principal amount under Telenet Facility AL , (b) the $300.0 million outstanding principal amount under the Telenet Facility AL Add-on and (c) the €730.0 million outstanding principal amount under Telenet Facility AM. In connection with these transactions, Telenet recognized a loss on debt modification and extinguishment, net, of $7.6 million related to the write-off of of unamortized deferred financing costs and discounts.

Accrued Income Taxes [Abstract]
Income Taxes	Income Taxes Income tax expense attributable to our loss from continuing operations before income taxes differs from the amounts computed using the applicable income tax rate as a result of the following factors: Three months ended Six months ended June 30, June 30, 2018 2017 2018 2017 in millions Computed “expected” tax benefit (expense) (a) $ (109.4 ) $ 133.3 $ 15.0 $ 188.0 Mandatory Repatriation Tax (b) 242.0 — (968.5 ) — Change in valuation allowances (b) (c): Expense 18.9 (102.2 ) (16.1 ) (169.6 ) Benefit (131.2 ) (2.0 ) 422.1 10.0 Basis and other differences in the treatment of items associated with investments in subsidiaries and affiliates (c): Expense (91.4 ) (41.3 ) (146.6 ) (80.8 ) Benefit (0.4 ) (0.1 ) 3.3 0.3 Non-deductible or non-taxable foreign currency exchange results (c): Expense 78.0 (103.4 ) (4.9 ) (132.5 ) Benefit 71.3 3.0 73.6 4.3 Non-deductible or non-taxable interest and other items (c): Expense (15.0 ) (5.7 ) (41.8 ) (52.6 ) Benefit 9.3 10.0 22.4 18.8 International rate differences (c) (d): Expense (13.5 ) (3.5 ) (22.6 ) (19.1 ) Benefit 15.5 41.4 31.2 75.3 Other, net 18.7 1.8 15.7 7.5 Total income tax benefit (expense) $ 92.8 $ (68.7 ) $ (617.2 ) $ (150.4 ) _______________ (a) The statutory or “expected” tax rates are U.K. rates of 19.0% for the 2018 periods and 19.25% for the 2017 periods. The statutory rate for the 2017 periods represents the blended rate in effect for the year ended December 31, 2017 based on the 20.0% statutory rate that was in effect for the first quarter of 2017 and the 19.0% statutory rate that was in effect for the remainder of 2017. (b) As further discussed below, the liability we have recorded for the Mandatory Repatriation Tax (as defined and described below) is significantly lower than the amount included in our income tax expense due primarily to the expected use of carryforward tax attributes in the U.S., all of which were subject to valuation allowances prior to the initial recognition of the Mandatory Repatriation Tax during the first quarter of 2018. (c) Country jurisdictions giving rise to income tax benefits are grouped together and shown separately from country jurisdictions giving rise to income tax expenses. (d) Amounts reflect adjustments (either a benefit or an expense) to the “expected” tax benefit for statutory rates in jurisdictions in which we operate outside of the U.K. The Tax Cuts and Jobs Act (the 2017 U.S. Tax Act ) was signed into law on December 22, 2017. In addition to lowering the U.S. corporate tax rate from 35% to 21% effective January 1, 2018, the 2017 U.S. Tax Act contains significant changes to the U.S. income tax regime, including (i) changes to the formation and use of net operating losses incurred after December 31, 2017, (ii) changes to the income tax deductibility of certain business expenses, including interest expense and compensation paid to certain executive officers, (iii) the imposition of taxes on a one-time deemed mandatory repatriation of earnings and profits of foreign corporations (the Mandatory Repatriation Tax ) and (iv) a new tax on global intangible low-taxed income. The Mandatory Repatriation Tax requires that the aggregate post-1986 earnings and profits of our foreign corporations be included in our U.S. taxable income. The one-time repatriation of undistributed foreign earnings and profits is then taxed at a rate of 15.5% for cash earnings and 8% for non-cash earnings, both as defined in the 2017 U.S. Tax Act , and is payable, interest free, over an eight year period according to a prescribed payment schedule with 45% of the tax due in the last two years. At June 30, 2018 , we have recorded an estimate of our liability for the Mandatory Repatriation Tax of $289.6 million after considering the expected use of carryforward tax attributes and other filing positions. Our estimate is subject to change during the remaining quarters of 2018 as we continue to refine the complex calculations, review various historical transactions and analyze substantial information that supports our ownership structure and the operating history of our foreign subsidiaries, as well as evaluate recent guidance from the tax authorities on the application of the tax laws underlying the Mandatory Repatriation Tax. At June 30, 2018 , our unrecognized tax benefits of $585.1 million included $425.9 million of tax benefits that would have a favorable impact on our effective income tax rate if ultimately recognized, after considering amounts that we would expect to be offset by valuation allowances and other factors. During the next 12 months, it is reasonably possible that the resolution of ongoing examinations by tax authorities, as well as the expiration of statutes of limitation, could result in reductions to our unrecognized tax benefits related to tax positions taken as of June 30, 2018 . The amount of any such reductions could range up to $125.0 million , all of which would have a positive impact on our effective tax rate. Other than the potential impacts of these ongoing examinations and the expected expiration of certain statutes of limitation, we do not expect any material changes to our unrecognized tax benefits during the next 12 months. No assurance can be given as to the nature or impact of any changes in our unrecognized tax positions during the next 12 months. We are currently undergoing income tax audits in Belgium, the Netherlands and the U.S. Except as noted below, any adjustments that might arise from the foregoing examinations are not expected to have a material impact on our consolidated financial position or results of operations. In the U.S.

(b) Represents annual incentive compensation and defined contribution plan liabilities that have been or are expected to be settled with Liberty Global ordinary shares. In the case of the annual incentive compensation, shares will be issued to senior management and key employees pursuant to a shareholding incentive program that was implemented in 2018. The shareholding incentive program allows these employees to elect to receive up to 100% of their annual incentive compensation in ordinary shares of Liberty Global in lieu of cash. The following table provides the aggregate number of options and share appreciation rights ( SAR s ) with respect to awards issued by Liberty Global that were (i) outstanding and (ii) exercisable as of June 30, 2018 . Class A Class C Number of shares underlying awards Weighted Average exercise or base price Number of shares underlying awards Weighted Average exercise or base price Held by Liberty Global employees: Outstanding 16,106,261 $ 32.28 37,449,896 $ 30.38 Exercisable 9,311,226 $ 31.85 22,890,732 $ 29.65 Held by former Liberty Global employees: Outstanding 1,202,625 $ 32.72 2,825,949 $ 30.54 Exercisable 952,952 $ 31.91 2,325,227 $ 29.64 The following table provides the aggregate number of restricted share units ( RSU s ) and PSU s that were outstanding as of June 30, 2018 : Class A Class C Held by Liberty Global employees: RSUs 640,075 1,265,060 PSUs 1,771,830 3,548,966 Held by former Liberty Global employees: RSUs 13,719 27,501 PSUs 172,971 346,299 2018 PSUs In March and May 2018, the compensation committee of our board of directors approved the grant of an aggregate 1,114,280 and 2,228,560 Class A and Class C PSU s, respectively, to executive officers and key employees (the 2018 PSUs ) pursuant to a performance plan that is based on the achievement of a specified compound annual growth rate ( CAGR ) with respect to our Adjusted OIBDA (as defined in note 16 ) during the two -year period ending December 31, 2019. The 2018 PSUs include over- and under-performance payout opportunities should the Adjusted OIBDA CAGR exceed or fail to meet the target, as applicable. A performance range of 50% to 125% of the target Adjusted OIBDA CAGR will generally result in award recipients earning 50% to 150% of their target 2018 PSUs , subject to reduction or forfeiture based on individual performance. The earned 2018 PSUs will vest 50% on April 1, 2020 and 50% on October 1, 2020. As of June 30, 2018, the target Adjusted OIBDA CAGR has not been yet been determined. Accordingly, no share-based compensation expense has been recognized related to the 2018 PSUs and the table above does not include the 2018 PSUs

Earnings Per Share [Abstract]
Earnings or Loss per Share	Earnings or Loss per Share Basic earnings or loss per share ( EPS ) is computed by dividing net earnings or loss by the weighted average number of shares outstanding for the period. Diluted EPS presents the dilutive effect, if any, on a per share basis of potential shares (e.g., options, SAR s, RSU s and PSU s) as if they had been exercised, vested or converted at the beginning of the periods presented. The details of our net earnings (loss) from continuing operations attributable to Liberty Global shareholders are set forth below: Three months ended Six months ended June 30, June 30, 2018 2017 2018 2017 in millions Earnings (loss) from continuing operations $ 668.7 $ (761.3 ) $ (696.3 ) $ (1,126.8 ) Net earnings from continuing operations attributable to noncontrolling interests (36.1 ) (4.8 ) (42.2 ) (39.8 ) Net earnings (loss) from continuing operations attributable to Liberty Global shareholders $ 632.6 $ (766.1 ) $ (738.5 ) $ (1,166.6 ) Our weighted average Liberty Global Share outstanding are set forth below: Three months ended Six months ended June 30, June 30, 2018 2017 2018 2017 Weighted average ordinary shares outstanding (Liberty Global Shares): Basic 788,815,021 853,612,217 798,215,803 871,936,668 Diluted 791,920,021 853,612,217 798,215,803 871,936,668 We reported losses from continuing operations attributable to Liberty Global shareholders for the six months ended June 30, 2018 and the three and six months ended June 30, 2017 . Therefore, the potentially dilutive effect at June 30, 2018 and 2017 of the following items were not included in the computation of diluted loss from continuing operations attributable to Liberty Global shareholders per share for such periods because their inclusion would have been anti-dilutive to the computation or, in the case of certain PSU s, because such awards had not yet met the applicable performance criteria: (i) the aggregate number of outstanding options, SAR s and RSU s of 59.5 million and 55.5 million , respectively, and (ii) the aggregate number of PSU s of 5.8 million and 7.3 million , respectively. The details of the calculations of our basic and diluted EPS from continuing operations for the three months ended June 30, 2018 are set forth in the following table: Numerator: Net earnings from continuing operations attributable to Liberty Global shareholders (basic and diluted EPS computation) (in millions) $ 632.6 Denominator (Liberty Global Shares): Weighted average ordinary shares (basic EPS computation) 788,815,021 Incremental shares attributable to the assumed exercise of outstanding options, SARs and the release of restricted shares and share units upon vesting (treasury stock method) 3,105,000 Weighted average ordinary shares outstanding (diluted EPS computation) 791,920,021 A total of 41.7 million options, SAR s and RSU s were excluded from the calculation of diluted earnings per share set forth in the table above because their effect would have been anti-dilutive.

The following table sets forth the U.S. dollar equivalents of such commitments for our continuing operations as of June 30, 2018 . The commitments included in this table do not reflect liabilities that are included in our June 30, 2018 condensed consolidated balance sheet. Payments due during: Remainder 2019 2020 2021 2022 2023 Thereafter Total in millions Network and connectivity commitments $ 402.8 $ 345.4 $ 283.4 $ 250.2 $ 67.5 $ 49.6 $ 787.8 $ 2,186.7 Programming commitments 544.1 792.9 470.3 227.7 40.3 14.7 46.6 2,136.6 Purchase commitments 506.7 306.9 136.2 47.7 20.8 17.5 38.6 1,074.4 Operating leases 70.4 99.6 79.0 60.0 47.8 40.1 151.0 547.9 Other commitments 9.8 15.2 2.8 0.4 0.2 — — 28.4 Total $ 1,533.8 $ 1,560.0 $ 971.7 $ 586.0 $ 176.6 $ 121.9 $ 1,024.0 $ 5,974.0 Programming commitments consist of obligations associated with certain of our programming, studio output and sports rights contracts that are enforceable and legally binding on us as we have agreed to pay minimum fees without regard to (i) the actual number of subscribers to the programming services, (ii) whether we terminate service to a portion of our subscribers or dispose of a portion of our distribution systems or (iii) whether we discontinue our premium sports services. Programming commitments do not include increases in future periods associated with contractual inflation or other price adjustments that are not fixed. Accordingly, the amounts reflected in the above table with respect to these contracts are significantly less than the amounts we expect to pay in these periods under these contracts. Historically, payments to programming vendors have represented a significant portion of our operating costs, and we expect that this will continue to be the case in future periods. In this regard, our total programming and copyright costs aggregated $805.1 million and $720.0 million during the six months ended June 30, 2018 and 2017 , respectively. Network and connectivity commitments include (i) Telenet ’s commitments for certain operating costs associated with its leased network, (ii) commitments associated with our MVNO agreements and (iii) service commitments associated with our network extension projects, primarily in the U.K. Telenet ’s commitments for certain operating costs are subject to adjustment based on changes in the network operating costs incurred by Telenet with respect to its own networks. These potential adjustments are not subject to reasonable estimation and, therefore, are not included in the above table. The amounts reflected in the above table with respect to certain of our MVNO commitments represent fixed minimum amounts payable under these agreements and, therefore, may be significantly less than the actual amounts we ultimately pay in these periods. Purchase commitments include unconditional and legally binding obligations related to (i) the purchase of customer premises and other equipment and (ii) certain service-related commitments, including call center, information technology and maintenance services. In addition to the commitments set forth in the table above, we have significant commitments under (i) derivative instruments and (ii) defined benefit plans and similar agreements, pursuant to which we expect to make payments in future periods. For information regarding our derivative instruments, including the net cash paid or received in connection with these instruments during the six months ended June 30, 2018 and 2017 , see note 6 . We also have commitments pursuant to agreements with, and obligations imposed by, franchise authorities and municipalities, which may include obligations in certain markets to move aerial cable to underground ducts or to upgrade, rebuild or extend portions of our broadband communication systems. Such amounts are not included in the above table because they are not fixed or determinable. Guarantees and Other Credit Enhancements In the ordinary course of business, we may provide (i) indemnifications to our lenders, our vendors and certain other parties and (ii) performance and/or financial guarantees to local municipalities, our customers and vendors. Historically, these arrangements have not resulted in our company making any material payments and we do not believe that they will result in material payments in the future. Legal and Regulatory Proceedings and Other Contingencies Interkabel Acquisition. On November 26, 2007 , Telenet and four associations of municipalities in Belgium, which we refer to as the pure intercommunales or the “ PICs ,” announced a non-binding agreement-in-principle to transfer the analog and digital television activities of the PICs , including all existing subscribers, to Telenet . Subsequently, Telenet and the PICs entered into a binding agreement (the 2008 PICs Agreement ), which closed effective October 1, 2008 . Beginning in December 2007 , Proximus NV/SA ( Proximus ), the incumbent telecommunications operator in Belgium, instituted several proceedings seeking to block implementation of these agreements. Proximus lodged summary proceedings with the President of the Court of First Instance of Antwerp to obtain a provisional injunction preventing the PICs from effecting the agreement-in-principle and initiated a civil procedure on the merits claiming the annulment of the agreement-in-principle. In March 2008 , the President of the Court of First Instance of Antwerp ruled in favor of Proximus in the summary proceedings, which ruling was overturned by the Court of Appeal of Antwerp in June 2008 . Proximus brought this appeal judgment before the Cour de Cassation (the Belgian Supreme Court ), which confirmed the appeal judgment in September 2010. On April 6, 2009 , the Court of First Instance of Antwerp ruled in favor of the PICs and Telenet in the civil procedure on the merits, dismissing Proximus ’s request for the rescission of the agreement-in-principle and the 2008 PICs Agreement . On June 12, 2009 , Proximus appealed this judgment with the Court of Appeal of Antwerp. In this appeal, Proximus is now also seeking compensation for damages. While these proceedings were suspended indefinitely, other proceedings were initiated, which resulted in a ruling by the Belgian Council of State in May 2014 annulling (i) the decision of the PICs not to organize a public market consultation and (ii) the decision from the PICs ’ board of directors to approve the 2008 PICs Agreement . In December 2015, Proximus resumed the civil proceedings pending with the Court of Appeal of Antwerp seeking to have the 2008 PICs Agreement annulled and claiming damages of €1.4 billion ( $1.6 billion ). In December 2017, the Court of Appeals of Antwerp issued a judgment rejecting Proximus’ claims. Proximus has the right to appeal the Court of Appeals of Antwerp’s judgment with the Belgian Supreme Court , however Proximus has not done so to date. No assurance can be given as to the outcome of these or other proceedings. However, an unfavorable outcome of existing or future proceedings could potentially lead to the annulment of the 2008 PICs Agreement and/or to an obligation of Telenet to pay compensation for damages, subject to the relevant provisions of the 2008 PICs Agreement , which stipulate that Telenet is responsible for damages in excess of €20.0 million ( $23.4 million ). We do not expect the ultimate resolution of this matter to have a material impact on our results of operations, cash flows or financial position. No amounts have been accrued by us with respect to this matter as the likelihood of loss is not considered to be probable. Telekom Deutschland Litigation. On December 28, 2012, Unitymedia filed a lawsuit against Telekom Deutschland GmbH ( Telekom Deutschland ), in which Unitymedia asserts that it pays excessive prices for the co-use of Telekom Deutschland ’s cable ducts in Unitymedia ’s footprint. The Federal Network Agency approved rates for the co-use of certain ducts of Telekom Deutschland in March 2011. Based in part on these approved rates, Unitymedia initially sought a reduction of the annual lease fees (approximately €76 million ( $89 million ) for 2017) by approximately two-thirds and has subsequently increased its claim to seek a reduction by approximately five-sixths . In addition, Unitymedia is seeking the return of similarly calculated overpayments from 2009 through the ultimate settlement date, plus accrued interest. In October 2016, the first instance court dismissed this action, and in March 2018, the court of appeal dismissed Unitymedia’s appeal of the first instance court’s decision and did not grant permission to appeal further to the Federal Court of Justice. Unitymedia has filed a motion with the Federal Court of Justice to grant permission to appeal. The resolution of this matter may take several years and no assurance can be given that Unitymedia ’s claims will be successful. Any recovery by Unitymedia will not be reflected in our consolidated financial statements until such time as the final disposition of this matter has been reached. If this matter is settled subsequent to the completion of the sale of the Vodafone Disposal Group , we would only share in 50% of any amounts recovered, plus 50% of the net present value of certain cost savings in future periods that are attributable to the favorable resolution of this matter, less 50% of associated legal or other third-party fees paid post-completion of the sale of the Vodafone Disposal Group . Belgium Regulatory Developments. In June 2018, the Belgisch Instituut voor Post en Telecommunicatie and the regional regulators for the media sectors (together, the Belgium Regulatory Authorities ) adopted a new decision finding that Telenet has significant market power in the wholesale broadband market (the 2018 Decision ). The 2018 Decision imposes on Telenet the obligations to (i) provide third-party operators with access to the digital television platform (including basic digital video and analog video) and (ii) make available to third-party operators a bitstream offer of broadband internet access (including fixed-line telephony as an option). Unlike prior decisions, the 2018 Decision no longer applies “retail minus” pricing on Telenet ; however, as of August 1, 2018, this decision imposes a 17% reduction in monthly wholesale cable resale access prices for an interim period. The Belgium Regulatory Authorities will replace these interim prices with “reasonable access tariffs” around mid-2019. The 2018 Decision aims to, and in its application, may strengthen Telenet ’s competitors by granting them resale access to Telenet ’s network to offer competing products and services notwithstanding Telenet ’s substantial historical financial outlays in developing the infrastructure. In addition, any resale access granted to competitors could (i) limit the bandwidth available to Telenet to provide new or expanded products and services to the customers served by its network and (ii) adversely impact Telenet ’s ability to maintain or increase its revenue and cash flows. The extent of any such adverse impacts ultimately will be dependent on the extent that competitors take advantage of the resale access afforded to Telenet ’s network, the rates that Telenet receives for such access and other competitive factors or market developments. Telenet considers the 2018 Decision to be inconsistent with the principle of technology-neutral regulation and the European Single Market Strategy to stimulate further investments in broadband networks and intends to challenge the 2018 Decision to the Brussels Court of Appeal. Virgin Media VAT Matters. Virgin Media ’s application of VAT with respect to certain revenue generating activities has been challenged by the U.K. tax authorities. Virgin Media has estimated its maximum exposure in the event of an unfavorable outcome to be £47 million ( $62 million ) as of June 30, 2018 . No portion of this exposure has been accrued by Virgin Media as the likelihood of loss is not considered to be probable. A court hearing was held at the end of September 2014 in relation to the U.K. tax authorities’ challenge and the timing of the court’s decision is uncertain. On March 19, 2014, the U.K. government announced a change in legislation with respect to the charging of VAT in connection with prompt payment discounts such as those that we offer to our fixed-line telephony customers. This change, which took effect on May 1, 2014, impacted our company and some of our competitors. The U.K. tax authority issued a decision in the fourth quarter of 2015 challenging our application of the prompt payment discount rules prior to the May 1, 2014 change in legislation. We have appealed this decision. As part of the appeal process, we were required to make aggregate payments of £67.0 million ( $99.1 million at the respective transaction dates), which included the challenged amount of £63.7 million and related interest of £3.3 million . The aggregate amount paid does not include penalties, which could be significant in the unlikely event that penalties were to be assessed. A court hearing was held in September 2017 and the timing of the court’s decision is uncertain. No portion of this potential exposure has been accrued by our company as the likelihood of loss is not considered to be probable. Ziggo Acquisition Matter. In July 2015, KPN N.V. appealed the European Commission ’s 2014 approval of the acquisition by Liberty Global of Ziggo Holding B.V. ( Ziggo ). We were not a party to that case. In October 2017, the E.U. General Court annulled the European Commission ’s approval on procedural grounds in that it found that the European Commission had failed to adequately explain the reasons for elements of its decision. We re-notified our acquisition of Ziggo to the European Commission for a new merger clearance, which was granted on May 30, 2018, and conditioned on remedies substantially similar to the remedies upon which the 2014 merger clearance was based. We consider this matter to be closed. Other Regulatory Issues. Video distribution, broadband internet, fixed-line telephony, mobile and content businesses are regulated in each of the countries in which we or our affiliates operate. The scope of regulation varies from country to country, although in some significant respects regulation in European markets is harmonized under the regulatory structure of the E.U. Adverse regulatory developments could subject our businesses to a number of risks. Regulation, including conditions imposed on us by competition or other authorities as a requirement to close acquisitions or dispositions, could limit growth, revenue and the number and types of services offered and could lead to increased operating costs and property and equipment additions. In addition, regulation may restrict our operations and subject them to further competitive pressure, including pricing restrictions, interconnect and other access obligations, and restrictions or controls on content, including content provided by third parties. Failure to comply with current or future regulation could expose our businesses to various penalties. Effective April 1, 2017, the rateable value of our existing network and other assets in the U.K. increased significantly. This increase affects the amount we pay for network infrastructure charges as the annual amount payable to the U.K. government is calculated by applying a percentage multiplier to the rateable value of assets. This change, together with a similar change in Ireland, has and will continue to significantly increase our network infrastructure charges. We expect the full year 2018 impact of this increase will be approximately £18 million ( $24 million ), as compared to 2017, and the impact will build to an aggregate increase of up to £110 million ( $145 million ) in 2021, as compared to the 12 months ended March 31, 2017. We continue to believe that these increases are excessive and retain the right of appeal should more favorable agreements be reached with other operators. The rateable value of network and other assets constructed under our network extension program in the U.K. remains subject to review by the U.K. government. In addition to the foregoing items, we have contingent liabilities related to matters arising in the ordinary course of business including (i) legal proceedings, (ii) issues involving VAT

Segment Reporting, Measurement Disclosures [Abstract]
Segment Reporting	Segment Reporting We generally identify our reportable segments as (i) those consolidated subsidiaries that represent 10% or more of our revenue, Adjusted OIBDA (as defined below) or total assets or (ii) those equity method affiliates where our investment or share of revenue or Adjusted OIBDA represents 10% or more of our total assets, revenue or Adjusted OIBDA , respectively. In certain cases, we may elect to include an operating segment in our segment disclosure that does not meet the above-described criteria for a reportable segment. We evaluate performance and make decisions about allocating resources to our operating segments based on financial measures such as revenue and Adjusted OIBDA . In addition, we review non-financial measures such as subscriber growth, as appropriate. Adjusted OIBDA is the primary measure used by our chief operating decision maker to evaluate segment operating performance and is also a key factor that is used by our internal decision makers to (i) determine how to allocate resources to segments and (ii) evaluate the effectiveness of our management for purposes of annual and other incentive compensation plans. As we use the term, “ Adjusted OIBDA ” is defined as operating income before depreciation and amortization, share-based compensation, provisions and provision releases related to significant litigation and impairment, restructuring and other operating items. Other operating items include (a) gains and losses on the disposition of long-lived assets, (b) third-party costs directly associated with successful and unsuccessful acquisitions and dispositions, including legal, advisory and due diligence fees, as applicable, and (c) other acquisition-related items, such as gains and losses on the settlement of contingent consideration. Our internal decision makers believe Adjusted OIBDA is a meaningful measure because it represents a transparent view of our recurring operating performance that is unaffected by our capital structure and allows management to (1) readily view operating trends, (2) perform analytical comparisons and benchmarking between segments and (3) identify strategies to improve operating performance in the different countries in which we operate. A reconciliation of Adjusted OIBDA from continuing operations to earnings (loss) from continuing operations before income taxes is presented below. As of June 30, 2018 , our reportable segments are as follows: Consolidated: • U.K./Ireland • Belgium • Switzerland • Central and Eastern Europe Nonconsolidated: • VodafoneZiggo JV Segment information for all periods has been retrospectively revised to present the LiLAC Group and our operating segments in Austria, Germany, Hungary, the Czech Republic and Romania as discontinued operations. As a result, (i) our former Switzerland/Austria reportable segment now only includes our operations in Switzerland and (ii) our Central and Eastern Europe segment now only includes (a) our broadband communications operations in Poland and Slovakia and (b) “ UPC DTH ”, which is a Luxembourg-based organization that provides direct-to-home satellite ( DTH ) services to customers in the Czech Republic, Hungary, Romania and Slovakia. Our central and corporate functions are included in an operating segment that we refer to as “ Central and Corporate ,” which primarily includes (1) revenue earned from services provided to the VodafoneZiggo JV and Liberty Latin America , (2) revenue from sales of customer premises equipment to the VodafoneZiggo JV and (3) costs associated with certain centralized functions, including billing systems, network operations, technology, marketing, facilities, finance and other administrative functions. On January 1, 2018, our wholesale handset program was transferred from Germany to an entity included in Central and Corporate . In connection with our presentation of our operating segment in Germany as a discontinued operation, the 2017 periods presented herein have been retrospectively revised to reflect this change. We present only the reportable segments of our continuing operations in the tables below. Performance Measures of Our Reportable Segments The amounts presented below represent 100% of each of our reportable segment’s revenue and Adjusted OIBDA . As we have the ability to control Telenet , we consolidate 100% of Telenet ’s revenue and expenses in our condensed consolidated statements of operations despite the fact that third parties own a significant interest. The noncontrolling owners’ interests in the operating results of Telenet and other less significant majority-owned subsidiaries are reflected in net earnings or loss attributable to noncontrolling interests in our condensed consolidated statements of operations. Similarly, despite only holding a 50% noncontrolling interest in the VodafoneZiggo JV , we present 100% of its revenue and Adjusted OIBDA in the tables below. Our share of the VodafoneZiggo JV 's operating results is included in share of losses of affiliates, net, in our condensed consolidated statements of operations.

Residential cable non-subscription revenue includes, among other items, channel carriage fees, late fees and revenue from the sale of equipment. As described in note 2 , we adopted ASU 2014-09 on January 1, 2018 using the cumulative effect transition method. For periods subsequent to our adoption of ASU 2014-09 , installation revenue is generally deferred and recognized over the contractual period as residential cable subscription revenue. For periods prior to the adoption of ASU 2014-09 , installation revenue is included in residential cable non-subscription revenue. (b) Residential subscription revenue from subscribers who purchase bundled services at a discounted rate is generally allocated proportionally to each service based on the standalone price for each individual service. As a result, changes in the standalone pricing of our cable and mobile products or the composition of bundles can contribute to changes in our product revenue categories from period to period. (c) Residential mobile subscription revenue includes amounts received from subscribers for ongoing services. Residential mobile non-subscription revenue includes, among other items, interconnect revenue and revenue from sales of mobile handsets and other devices. (d) B2B subscription revenue represents revenue from services to certain small or home office ( SOHO ) subscribers. SOHO subscribers pay a premium price to receive expanded service levels along with video, broadband internet, fixed-line telephony or mobile services that are the same or similar to the mass marketed products offered to our residential subscribers. B2B non-subscription revenue includes business broadband internet, video, fixed-line telephony, mobile and data services offered to medium to large enterprises and, on a wholesale basis, to other operators. (e) Other revenue includes, among other items, revenue earned from the JV Services, broadcasting revenue in Ireland and revenue from Central and Corporate’s wholesale handset program. In addition, the 2018 periods include revenue earned from (i) sales of customer premises equipment to the VodafoneZiggo JV and (ii) services provided to Liberty Latin America.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes ASU 2014-09 In May 2014, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2014-09, Revenue from Contracts with Customers ( ASU 2014-09 ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services to customers. We adopted ASU 2014-09 effective January 1, 2018 by recording the cumulative effect of the adoption to our accumulated deficit. We applied the new standard to contracts that were not complete at January 1, 2018. The comparative information for the three and six months ended June 30, 2017 contained within these condensed consolidated financial statements and notes has not been restated and continues to be reported under the accounting standards in effect for such period. The implementation of ASU 2014-09 did not have a material impact on our consolidated financial statements. The principal impacts of ASU 2014-09 on our revenue recognition policies relate to our accounting for (i) time-limited discounts and free service periods provided to our customers and (ii) certain upfront fees charged to our customers, as follows: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under previous accounting rules, we recognized revenue, net of discounts, during the promotional periods and did not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition for those contracts that contain substantive termination penalties is accelerated, as the impact of the discounts or free service periods is recognized uniformly over the contractual period. For contracts that do not have substantive termination penalties, we continue to record the impacts of partial or full discounts during the applicable promotional periods. • When we enter into contracts to provide services to our customers, we often charge installation or other upfront fees. Under previous accounting rules, installation fees related to services provided over our cable networks were recognized as revenue during the period in which the installation occurred to the extent these fees were equal to or less than direct selling costs. Under ASU 2014-09 , these fees are generally deferred and recognized as revenue over the contractual period, or longer if the upfront fee results in a material renewal right. ASU 2014-09 also impacted our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our previous policy, these costs were expensed as incurred unless the costs were in the scope of another accounting topic that allowed for capitalization. Under ASU 2014-09 , certain upfront costs associated with contracts that have substantive termination penalties and a term of one year or more are recognized as assets and amortized to operating costs and expenses over the applicable period benefited. For additional information regarding our adoption of ASU 2014-09 , see note 3 . The cumulative effect of the adoption of ASU 2014-09 on our summary balance sheet information as of January 1, 2018 is as follows: Balance at December 31, 2017 ASU 2014-09 Adjustments Balance at January 1, 2018 in millions Assets: Trade receivables, net $ 1,411.0 (0.7 ) $ 1,410.3 Current assets of discontinued operations $ 268.1 98.2 $ 366.3 Other current assets $ 351.9 76.6 $ 428.5 Investments and related note receivables (a) $ 6,671.4 191.2 $ 6,862.6 Deferred tax assets $ 3,133.1 (16.0 ) $ 3,117.1 Long-term assets of discontinued operations $ 11,141.1 29.1 $ 11,170.2 Other assets, net $ 3,720.2 21.4 $ 3,741.6 Liabilities: Deferred revenue $ 942.2 5.6 $ 947.8 Current liabilities of discontinued operations $ 1,587.7 26.7 $ 1,614.4 Other accrued and current liabilities $ 2,240.0 1.2 $ 2,241.2 Long-term liabilities of discontinued operations $ 9,967.6 39.1 $ 10,006.7 Other long-term liabilities $ 2,247.0 2.7 $ 2,249.7 Equity: Accumulated deficit (a) $ (6,217.6 ) 320.1 $ (5,897.5 ) Noncontrolling interests $ (412.0 ) 4.4 $ (407.6 ) _______________ (a) The ASU 2014-09 adjustment amounts include the impact of our share of the VodafoneZiggo JV ’s adjustment to its owners’ equity. The impact of our adoption of ASU 2014-09 on our condensed consolidated balance sheet as of June 30, 2018 was not materially different from the impacts set forth in the above January 1, 2018 summary balance sheet information. Similarly, the adoption of ASU 2014-09 did not have a material impact on our condensed consolidated statement of operations for the three and six months ended June 30, 2018 . ASU 2017-07 In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of the Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ( ASU 2017-07 ), which changes the presentation of periodic benefit cost components. Under ASU 2017-07 , we continue to present the service component of our net benefit cost as a component of operating income but present the other components of our net benefit cost, which can include credits, within non-operating income (expense) in our consolidated statements of operations. We adopted ASU 2017-07 on January 1, 2018 on a retrospective basis, which resulted in the reclassification of credits from SG&A expenses to other income, net, of $9.2 million for the six months ended June 30, 2017. ASU 2016-01 In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities ( ASU 2016-01 ), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 primarily impacts our accounting for certain equity investments that were previously accounted for under the cost method. Under ASU 2016-01 , these investments, which do not have readily determinable fair values, are accounted for at cost minus impairment, adjusted for any observable price changes of similar investments of the same issuer. We adopted the amendments of ASU 2016-01 related to equity securities without readily determinable fair values on January 1, 2018 on a prospective basis. ASU 2016-18 In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash ( ASU 2016-18 ), which requires the change in restricted cash to be included together with the change in cash and cash equivalents in our consolidated statement of cash flows. We adopted ASU 2016-18 on January 1, 2018 on a retrospective basis. Recent Accounting Pronouncements ASU 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases ( ASU 2016-02 ), which, for most leases, will result in lessees recognizing right-of-use assets and lease liabilities on the balance sheet and additional disclosures. ASU 2016-02 , as amended by ASU No. 2018-11, Targeted Improvements , requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using one of two modified retrospective approaches. A number of optional practical expedients may be applied in transition. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. We will adopt ASU 2016-02 on January 1, 2019 by recording the cumulative effect of adoption to our accumulated deficit. Although we are currently evaluating the effect that ASU 2016-02 will have on our consolidated financial statements, the main impact of the adoption of this standard will be the recognition of right-of-use assets and lease liabilities in our consolidated balance sheet for those leases classified as operating leases under current U.S. GAAP . We do not intend to recognize right-of-use assets or lease liabilities for leases with a term of 12 months or less, as permitted by the short-term lease practical expedient in the standard. We also do not plan to apply the practical expedient that permits a lessee to account for lease and non-lease components in a contract as a single lease component and, accordingly, we will continue to account for these components separately. In transition, we plan to apply the practical expedients that permit us not to reassess (i) whether expired or existing contracts contain a lease under the new standard, (ii) the lease classification for expired or existing leases or (iii) whether previously-capitalized initial direct costs would qualify for capitalization under the new standard. In addition, we do not intend to use hindsight during transition. For a summary of our undiscounted future minimum lease payments under non-cancellable operating leases as of June 30, 2018 , see note 15 . We currently do not expect ASU 2016-02 to have a significant impact on our consolidated statements of operations or cash flows.
Revenue Recognition and Related Costs	Policies Our revenue recognition and certain other accounting policies, as revised to reflect the impacts of our adoption of ASU 2014-09 , are set forth below. Service Revenue — Cable Networks. We recognize revenue from the provision of video, broadband internet and fixed-line telephony services over our cable network to customers in the periods the related services are provided, with the exception of revenue recognized pursuant to certain contracts that contain promotional discounts, as described below. Installation fees related to services provided over our cable network are generally deferred and recognized as revenue over the contractual period, or longer if the upfront fee results in a material renewal right. Sale of Multiple Products and Services. We sell video, broadband internet, fixed-line telephony and, in most of our markets, mobile services to our customers in bundled packages at a rate lower than if the customer purchased each product on a standalone basis. Revenue from bundled packages generally is allocated proportionally to the individual products or services based on the relative standalone selling price for each respective product or service. Mobile Revenue — General. Consideration from mobile contracts is allocated to the airtime service component and the handset component based on the relative standalone selling prices of each component. In markets where we offer handsets and airtime services in separate contracts entered into at the same time, we account for these contracts as a single contract. Mobile Revenue — Airtime Services. We recognize revenue from mobile services in the periods in which the related services are provided. Revenue from pre-pay customers is deferred prior to the commencement of services and recognized as the services are rendered or usage rights expire. Mobile Revenue — Handset Revenue. Revenue from the sale of handsets is recognized at the point in which the goods have been transferred to the customer. Some of our mobile handset contracts that permit the customer to take control of the handset upfront and pay for the handset in installments over a contractual period may contain a significant financing component. For contracts with terms of one year or more, we recognize any significant financing component as revenue over the contractual period using the effective interest method. We do not record the effect of a significant financing component if the contractual period is less than one year. B2B Revenue. We defer upfront installation and certain nonrecurring fees received on B2B contracts where we maintain ownership of the installed equipment. The deferred fees are amortized into revenue on a straight-line basis, generally over the longer of the term of the arrangement or the expected period of performance. Contract Costs. Incremental costs to obtain a contract with a customer, such as incremental sales commissions, are generally recognized as assets and amortized to SG&A expenses over the applicable period benefited, which generally is the contract life. If, however, the amortization period is less than one year, we expense such costs in the period incurred. Contract fulfillment costs, such as porting costs, are recognized as assets and amortized to other operating costs over the applicable period benefited, which is generally the substantive contract term for the related service contract. Promotional Discounts. For subscriber promotions, such as discounted or free services during an introductory period, revenue is recognized uniformly over the contractual period if the contract has substantive termination penalties. If a contract does not have substantive termination penalties, revenue is recognized only to the extent of the discounted monthly fees charged to the subscriber, if any. Subscriber Advance Payments. Payments received in advance for the services we provide are deferred and recognized as revenue when the associated services are provided. Sales, Use and Other Value-Added Taxes. Revenue is recorded net of applicable sales, use and other value-added taxes. For a disaggregation of our revenue by major category and by reportable and geographic segment, see note 16 . Contract Balances The timing of revenue recognition may differ from the timing of invoicing our customers. We record a trade receivable when we have transferred goods or services to a customer but have not yet received payment. Our trade receivables are reported net of an allowance for doubtful accounts. Such allowance aggregated $57.0 million and $89.5 million at June 30, 2018 and January 1, 2018, respectively. If we transfer goods or services to a customer but do not have an unconditional right to payment, we record a contract asset. Contract assets typically arise from the uniform recognition of introductory promotional discounts over the contract period and accrued revenue for handset sales. Our contract assets were $27.7 million and $26.1 million as of June 30, 2018 and January 1, 2018, respectively. The current and long-term portions of our contract asset balance at June 30, 2018 are included within other current assets and other assets, net, respectively, in our condensed consolidated balance sheet. We record deferred revenue when we receive payment prior to transferring goods or services to a customer. We primarily defer revenue for (i) installation and other upfront services and (ii) other services that are invoiced prior to when services are provided. Our deferred revenue balances were $889.2 million and $1,005.2 million as of June 30, 2018 and January 1, 2018, respectively. The decrease in deferred revenue for the six months ended June 30, 2018 is primarily due to $801.8 million of revenue recognized that was included in our deferred revenue balance at January 1, 2018, partially offset by advanced billings in certain markets. The current and long-term portions of our deferred revenue balance at June 30, 2018 are included within deferred revenue and other long-term liabilities, respectively, in our condensed consolidated balance sheet. Contract Costs Our aggregate assets associated with incremental costs to obtain and fulfill our contracts were $68.4 million and $68.1 million at June 30, 2018 and January 1, 2018, respectively. The current and long-term portions of our assets related to contract costs at June 30, 2018 are included within other current assets and other assets, net, respectively, in our condensed consolidated balance sheet. We amortized $28.5 million and $51.3 million to operating costs and expenses during the three and six months ended June 30, 2018 , respectively, related to these assets. Unsatisfied Performance Obligations A large portion of our revenue is derived from customers who are not subject to contracts. Revenue from customers who are subject to contracts is generally recognized over the term of such contracts, which is typically 12 months for our residential service, one to three years for our mobile contracts and one to five years for our B2B

(b) We consider credit risk relating to our and our counterparties’ nonperformance in the fair value assessment of our derivative instruments. In all cases, the adjustments take into account offsetting liability or asset positions within each of our subsidiary borrowing groups (as defined and described in note 9 ). The changes in the credit risk valuation adjustments associated with our cross-currency and interest rate derivative contracts resulted in a net gain (loss) of ( $65.6 million ) and $59.6 million during the three months ended June 30, 2018 and 2017 , respectively, and a net gain (loss) of ( $27.9 million ) and $109.0 million during the six months ended June 30, 2018 and 2017 , respectively. These amounts are included in realized and unrealized gains (losses) on derivative instruments, net, in our condensed consolidated statements of operations. For further information regarding our fair value measurements, see note 7 . (c) Our equity-related derivative instruments primarily include the fair value of (i) the share collar (the ITV Collar ) with respect to ITV shares held by our company, (ii) the prepaid forward transaction (the Lionsgate Forward ) with respect to 1.25 million of our voting and 1.25 million of our non-voting Lionsgate shares and (iii) at December 31, 2017, the share collar (the Sumitomo Collar ) with respect to a portion of the shares of Sumitomo held by our company.

The interest rates presented represent stated rates and do not include the impact of derivative instruments, deferred financing costs, original issue premiums or discounts and commitment fees, all of which affect our overall cost of borrowing. Including the effects of derivative instruments, original issue premiums or discounts and commitment fees, but excluding the impact of deferred financing costs, our weighted average interest rate on our aggregate variable- and fixed-rate indebtedness was 3.98% at June 30, 2018 . For information regarding our derivative instruments, see note 6 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at June 30, 2018 without regard to covenant compliance calculations or other conditions precedent to borrowing. At June 30, 2018 , based on the most restrictive applicable leverage covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, and based on the most restrictive applicable leverage-based restricted payment tests, there were no restrictions on the respective subsidiary's ability to make loans or distributions from this availability to Liberty Global or its subsidiaries or other equity holders, except as shown in the table below. In the following table we present, based on the most restrictive applicable leverage covenants, leverage-based restricted payment tests and other limitations in effect for each borrowing group, (i) for each subsidiary where the ability to borrow is limited, the actual borrowing availability under the respective facility and (ii) for each subsidiary where the ability to make loans or distributions from this availability is limited, the amount that can be loaned or distributed to Liberty Global or its subsidiaries or other equity holders. The amounts presented below do not consider any actual or potential changes to our borrowing levels subsequent to June 30, 2018 and are based on the most restrictive applicable leverage-based restricted payment tests and covenant and other limitations in effect for each borrowing group at June 30, 2018, both before and after considering the impact of the completion of the June 30, 2018 compliance requirements.

The discount rates used in the cash flow models are based on the market interest rates and estimated credit spreads of the applicable entity, to the extent available, and other relevant factors. For additional information regarding fair value hierarchies, see note 7 . (d) As further described in note 4 , subsequent to June 30, 2018, we used a portion of the net proceeds from the sale of UPC Austria to repay or redeem certain debt of the UPC Holding and Virgin Media borrowing groups. (e) Unused borrowing capacity under the VM Credit Facilities relates to multi-currency revolving facilities with an aggregate maximum borrowing capacity equivalent to £675.0 million ( $890.6 million ). In February 2018, the VM Revolving Facility was amended and split into two revolving facilities. VM Revolving Facility A is a multi-currency revolving facility maturing on December 31, 2021 with a maximum borrowing capacity equivalent to £75.0 million ( $98.9 million ), and VM Revolving Facility B is a multi-currency revolving facility maturing on January 15, 2024 with a maximum borrowing capacity equivalent to £600.0 million ( $791.7 million ). All other terms from the previously existing VM Revolving Facility continue to apply to the new revolving facilities (f) Unused borrowing capacity under the Telenet Credit Facility comprises (i) €400.0 million ( $467.1 million ) under Telenet Facility AG, (ii) €25.0 million ( $29.2 million ) under the Telenet Overdraft Facility and (iii) €20.0 million ( $23.4 million ) under the Telenet Revolving Facility, each of which were undrawn at June 30, 2018 . (g) Represents amounts owed pursuant to interest-bearing vendor financing arrangements that are used to finance certain of our property and equipment additions and, to a lesser extent, certain of our operating expenses. These obligations are generally due within one year and include VAT that was paid on our behalf by the vendor. Repayments of vendor financing obligations are included in repayments and repurchases of debt and capital lease obligations in our condensed consolidated statements of cash flows. (h) The Sumitomo Share Loan is carried at fair value. For information regarding fair value hierarchies, see note 7 . (i) Represents amounts associated with certain derivative-related borrowing instruments, including $281.1 million and $304.9 million at June 30, 2018 and December 31, 2017 , respectively, carried at fair value.

The statutory rate for the 2017 periods represents the blended rate in effect for the year ended December 31, 2017 based on the 20.0% statutory rate that was in effect for the first quarter of 2017 and the 19.0% statutory rate that was in effect for the remainder of 2017. (b) As further discussed below, the liability we have recorded for the Mandatory Repatriation Tax (as defined and described below) is significantly lower than the amount included in our income tax expense due primarily to the expected use of carryforward tax attributes in the U.S., all of which were subject to valuation allowances prior to the initial recognition of the Mandatory Repatriation Tax during the first quarter of 2018. (c) Country jurisdictions giving rise to income tax benefits are grouped together and shown separately from country jurisdictions giving rise to income tax expenses. (d) Amounts reflect adjustments (either a benefit or an expense) to the “expected” tax benefit for statutory rates in jurisdictions in which we operate outside of the U.K.

As described in note 2 , we adopted ASU 2014-09 on January 1, 2018 using the cumulative effect transition method. For periods subsequent to our adoption of ASU 2014-09 , installation revenue is generally deferred and recognized over the contractual period as residential cable subscription revenue. For periods prior to the adoption of ASU 2014-09 , installation revenue is included in residential cable non-subscription revenue. (b) Residential subscription revenue from subscribers who purchase bundled services at a discounted rate is generally allocated proportionally to each service based on the standalone price for each individual service. As a result, changes in the standalone pricing of our cable and mobile products or the composition of bundles can contribute to changes in our product revenue categories from period to period. (c) Residential mobile subscription revenue includes amounts received from subscribers for ongoing services. Residential mobile non-subscription revenue includes, among other items, interconnect revenue and revenue from sales of mobile handsets and other devices. (d) B2B subscription revenue represents revenue from services to certain small or home office ( SOHO ) subscribers. SOHO subscribers pay a premium price to receive expanded service levels along with video, broadband internet, fixed-line telephony or mobile services that are the same or similar to the mass marketed products offered to our residential subscribers. B2B non-subscription revenue includes business broadband internet, video, fixed-line telephony, mobile and data services offered to medium to large enterprises and, on a wholesale basis, to other operators. (e) Other revenue includes, among other items, revenue earned from the JV Services, broadcasting revenue in Ireland and revenue from Central and Corporate’s wholesale handset program. In addition, the 2018 periods include revenue earned from (i) sales of customer premises equipment to the VodafoneZiggo JV and (ii) services provided to Liberty Latin America.
