Organization, Consolidation and Presentation of Financial Statements [Abstract]
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, with consolidated operations at June 30, 2017 in more than 30 countries. In Europe, we provide residential and business-to-business ( B2B ) communications services in (i) the United Kingdom ( U.K. ) and Ireland through Virgin Media Inc. ( Virgin Media ), (ii) Germany through Unitymedia GmbH ( Unitymedia ), (iii) Belgium through Telenet Group Holding N.V. ( Telenet ), a 57.3% -owned subsidiary, and (iv) seven other European countries through UPC Holding B.V. ( UPC Holding ). In addition, through the December 31, 2016 completion of the VodafoneZiggo JV Transaction (as defined and described in note 4 ), we provided residential and B2B communications services in the Netherlands through VodafoneZiggo Group B.V., which is referred to herein as “ Ziggo Group Holding ”. Following the completion of the VodafoneZiggo JV Transaction , we own a 50% noncontrolling interest in the VodafoneZiggo JV (as defined in note 4 ), which provides video, broadband internet, mobile and B2B services in the Netherlands. Virgin Media , Unitymedia and UPC Holding are each wholly-owned subsidiaries of Liberty Global . The operations of Virgin Media , Unitymedia , Telenet , UPC Holding and, through December 31, 2016, Ziggo Group Holding are collectively referred to herein as the “ European Division .” Outside of Europe, we provide residential and B2B communications services in (i) 18 countries, predominantly in Latin America and the Caribbean, through our wholly-owned subsidiary Cable & Wireless Communications Limited ( CWC ), (ii) Chile through our wholly-owned subsidiary VTR.com SpA ( VTR ) and (iii) Puerto Rico through Liberty Cablevision of Puerto Rico LLC ( Liberty Puerto Rico ), an entity in which we hold a 60.0% ownership interest. CWC also provides (a) B2B communications services in certain other countries in Latin America and the Caribbean and (b) wholesale communications services over its sub-sea and terrestrial fiber optic cable network that connects over 40 markets in that region. CWC owns less than 100% of certain of its consolidated subsidiaries, including Cable & Wireless Panama, SA (a 49.0% -owned entity that owns most of our operations in Panama), The Bahamas Telecommunications Company Limited (a 49.0% -owned entity that owns all of our operations in the Bahamas), Cable & Wireless Jamaica Limited (an 82.0% -owned entity that owns the majority of our operations in Jamaica) and Cable & Wireless Barbados Limited (an 81.1% -owned entity that owns the majority of our operations in Barbados). The operations of CWC , VTR and Liberty Puerto Rico are collectively referred to herein as the “ LiLAC Division .” Our share capital comprises (i) Class A, B and C Liberty Global ordinary shares (collectively, Liberty Global Shares ) and (ii) Class A, B and C LiLAC ordinary shares (collectively, LiLAC Shares ). The Liberty Global Shares and the LiLAC Shares are tracking shares. Tracking shares are intended by the issuing company to reflect or “track” the economic performance of a particular business or “group,” rather than the economic performance of the company as a whole. The Liberty Global Shares and the LiLAC Shares are intended to track the economic performance of the Liberty Global Group and the LiLAC Group , respectively (each as defined below). While the Liberty Global Group and the LiLAC Group have separate collections of businesses, assets and liabilities attributed to them, neither group is a separate legal entity and therefore cannot own assets, issue securities or enter into legally binding agreements. Holders of tracking shares have no direct claim to the group’s assets and are not represented by separate boards of directors. Instead, holders of tracking shares are shareholders of the parent corporation, with a single board of directors, and are subject to all of the risks and liabilities of the parent corporation. We and our subsidiaries each continue to be responsible for our respective liabilities. Holders of Liberty Global Shares , LiLAC Shares and any other of our capital shares designated as ordinary shares from time to time will continue to be subject to risks associated with an investment in our company as a whole, even if a holder does not own both Liberty Global Shares and LiLAC Shares . The “ LiLAC Group ” comprises our businesses, assets and liabilities in Latin America and the Caribbean and has attributed to it (i) LGE Coral Holdco Limited ( LGE Coral ) and its subsidiaries, which include CWC , (ii) VTR Finance B.V. ( VTR Finance ) and its subsidiaries, which include VTR , (iii) Lila Chile Holding B.V. ( Lila Chile Holding ), which is the parent entity of VTR Finance and (iv) LiLAC Communications Inc. ( LiLAC Communications ) and its subsidiaries, which include Liberty Puerto Rico . The “ Liberty Global Group ” comprises our businesses, assets and liabilities not attributed to the LiLAC Group , including Virgin Media , Unitymedia , Telenet , UPC Holding , our 50% interest in the VodafoneZiggo JV (from December 31, 2016), Ziggo Group Holding (up to December 31, 2016), our corporate entities (excluding LiLAC Communications ) and certain other less significant entities. For additional information regarding our tracking share capital structure, including unaudited attributed financial information of the Liberty Global Group and the LiLAC Group , see Exhibit 99.1 to this Quarterly Report on Form 10-Q. 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 2016 consolidated financial statements and notes thereto included in our 2016 Annual Report on Form 10-K, as amended (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, 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, 2017 .

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes and Recent Accounting Pronouncements Accounting Changes In March 2016, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2016-09, Compensation — Stock Compensation, Improvements to Employee Share-Based Payment Accounting ( ASU 2016-09 ), which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification within the statement of cash flows. We adopted ASU 2016-09 on January 1, 2017. As a result of adopting this standard, we (i) recognized a cumulative effect adjustment to our accumulated deficit as of January 1, 2017 and (ii) retrospectively revised the presentation of our condensed consolidated statements of cash flows to remove the operating cash outflows and financing cash inflows associated with excess tax benefits from share-based compensation. The cumulative effect adjustment, which totaled $15.3 million , represents the tax effect of deductions in excess of the financial reporting expense for share-based compensation that were not previously recognized for financial reporting purposes as these tax benefits were not realized as a reduction of income taxes payable. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment ( ASU 2017-04 ), which eliminates the requirement to estimate the implied fair value of a reporting unit’s goodwill as determined following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, a company should recognize any goodwill impairment by comparing the fair value of a reporting unit to its carrying amount. We early-adopted ASU 2017-04 effective January 1, 2017. The adoption of ASU 2017-04 , which reduces the complexity surrounding the evaluation of our goodwill for impairment, had no immediate impact on our impairment evaluations. Recent Accounting Pronouncements ASU 2014-09 In May 2014, the FASB issued 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 promised goods or services to customers. ASU 2014-09 , as amended by ASU No. 2015-14, will replace existing revenue recognition guidance when it becomes effective for annual and interim reporting periods beginning after December 15, 2017. This new standard permits the use of either the retrospective or cumulative effect transition method. We will adopt ASU 2014-09 effective January 1, 2018 using the cumulative effect transition method. While we are continuing to evaluate the effect that ASU 2014-09 will have on our consolidated financial statements, we have identified a number of our current revenue recognition policies that will be impacted by ASU 2014-09 , including the accounting for (i) time-limited discounts and free service periods provided to our customers and (ii) certain up-front fees charged to our customers. These impacts are discussed below: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under current accounting rules, we recognize revenue net of discounts during the promotional periods and do not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition will be accelerated for these contracts as the impact of the discount or free service period will be recognized uniformly over the total contractual period. • When we enter into contracts to provide services to our customers, we often charge installation or other up-front fees. Under current accounting rules, installation fees related to services provided over our cable networks are recognized as revenue during the period in which the installation occurs to the extent these fees are equal to or less than direct selling costs. Under ASU 2014-09 , these fees will generally be deferred and recognized as revenue over the contractual period, or longer if the up-front fee results in a material renewal right. As the above revenue recognition changes have offsetting impacts and both result in a relatively minor shift in the timing of revenue recognition, we currently do not expect ASU 2014-09 to have a material impact on our consolidated revenue. ASU 2014-09 will also impact our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our current policy, these costs are expensed as incurred unless the costs are in the scope of another accounting topic that allows for capitalization. Under ASU 2014-09 , the upfront costs that are currently expensed as incurred will be recognized as assets and amortized to other operating expenses over a period that is consistent with the transfer to the customers of the goods or services to which the assets relate, which we have generally interpreted to be the expected life of the customer relationship. The impact of the accounting change for these costs will be dependent on numerous factors, including the number of new subscriber contracts added in any given period, but we expect the adoption of this accounting change will initially result in the deferral of a significant amount of operating and selling costs. The ultimate impact of adopting ASU 2014-09 for both revenue recognition and costs to obtain and fulfill contracts will depend on the promotions and offers in place during the period leading up to and after the adoption of ASU 2014-09 . 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 lease assets and lease liabilities on the balance sheet with additional disclosures about leasing arrangements. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach also includes a number of optional practical expedients an entity may elect to apply. 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. 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 lease assets and lease liabilities in our consolidated balance sheets for those leases classified as operating leases under previous U.S. GAAP . ASU 2016-02 will not have significant impacts on our consolidated statements of operations or cash flows. 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 will 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 computation, which can include credits, within non-operating income (expense) in our consolidated statements of operations. ASU 2017-07 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted for interim or annual periods. We are currently evaluating the effect that ASU 2017-07

Business Combinations [Abstract]
Acquisitions	Acquisitions Pending Acquisitions Multimedia . On October 18, 2016, our subsidiary UPC Polska SP Z.o.o. entered into a definitive agreement to acquire the cable business of Multimedia Polska S.A. ( Multimedia ), the third-largest cable operator in Poland, for cash consideration of 3.0 billion Polish zlotys ( $809.6 million ), which is equal to the enterprise value assigned to Multimedia for purposes of this transaction. We intend to finance the acquisition of Multimedia with existing liquidity. The final purchase price is subject to potential downward adjustments for the operational and financial performance of Multimedia prior to closing. The transaction is subject to customary closing conditions, including regulatory approval, and is expected to close in late 2017 or early 2018. 2017 Acquisitions Carve-out Entities . In connection with the CWC Acquisition , as defined and described below, and an acquisition made by CWC in 2015, certain entities (the Carve-out Entities ) that hold licenses granted by the U.S. Federal Communications Commission (the FCC ) were transferred to entities not controlled by our company or CWC . The arrangements with respect to the Carve-out Entities , which were executed in connection with the CWC Acquisition and the acquisition made by CWC in 2015, contemplated that upon receipt of regulatory approval, CWC would acquire the Carve-out Entities . On March 8, 2017, the FCC granted its approval for CWC ’s acquisition of the Carve-out Entities . Accordingly, on April 1, 2017, subsidiaries of CWC acquired the Carve-out Entities (the CWC Carve-out Acquisition ) for an aggregate purchase price of $86.2 million , which represents the amount due under notes receivable that were exchanged for the equity of the Carve-out Entities . SFR BeLux . On June 19, 2017 , Telenet acquired Coditel Brabant sprl, operating under the SFR brand ( SFR BeLux ), for €391.0 million ( $453.2 million at the transaction date) on a cash and debt free basis (the SFR BeLux Acquisition ). SFR BeLux provides cable services to households and businesses in Brussels, Wallonia and Luxembourg and offers mobile services in Belgium through a mobile virtual network operator ( MVNO ) agreement with BASE , as defined and described below. The SFR BeLux Acquisition was funded through a combination of €210.0 million ( $239.7 million ) of borrowings under the Telenet Credit Facility and existing liquidity of Telenet . 2016 Acquisitions CWC . On May 16, 2016 , we acquired CWC for shares of Liberty Global (the CWC Acquisition ). The CWC Acquisition triggered regulatory approval requirements in certain jurisdictions in which CWC operates. The regulatory authorities in certain of these jurisdictions, including the Bahamas, Jamaica, Trinidad and Tobago and the Seychelles, have not completed their review of the CWC Acquisition or granted their approval. While we expect to receive all outstanding approvals, such approvals may include binding conditions or requirements that could have an adverse impact on CWC ’s operations and financial condition. We have accounted for the CWC Acquisition using the acquisition method of accounting, whereby the total purchase price was allocated to the acquired identifiable net assets of CWC based on assessments of their respective fair values, and the excess of the purchase price over the fair values of these identifiable net assets was allocated to goodwill. A summary of the purchase price and the opening balance sheet of CWC at the May 16, 2016 acquisition date is presented in the following table. The opening balance sheet presented below reflects our final purchase price allocation (in millions): Cash and cash equivalents $ 210.8 Other current assets 578.5 Property and equipment, net 2,914.2 Goodwill (a) 5,344.3 Intangible assets subject to amortization, net (b) 1,416.0 Other assets, net 577.8 Current portion of debt and capital lease obligations (94.1 ) Other accrued and current liabilities (753.2 ) Long-term debt and capital lease obligations (3,305.4 ) Other long-term liabilities (751.8 ) Noncontrolling interests (c) (1,453.2 ) Total purchase price (d) $ 4,683.9 _______________ (a) The goodwill recognized in connection with the CWC Acquisition is primarily attributable to (i) the ability to take advantage of CWC ’s existing terrestrial and sub-sea networks to gain immediate access to potential customers and (ii) synergies that are expected to be achieved through the integration of CWC with other operations in the LiLAC Group . (b) Amount primarily includes intangible assets related to customer relationships. The weighted average useful life of CWC ’s intangible assets at the May 16, 2016 acquisition date was approximately nine years . (c) Represents the estimated aggregate fair value of the noncontrolling interests in CWC ’s subsidiaries as of May 16, 2016 . (d) The total purchase price (i) includes the issuance of Liberty Global Shares and LiLAC Shares that were collectively valued at $4,490.1 million and a special cash dividend of $193.8 million and (ii) excludes direct acquisition costs of $135.0 million , most of which were incurred during 2016. Direct acquisition costs are included in impairment, restructuring and other operating items, net, in our consolidated statements of operations. BASE . On February 11, 2016 , Telenet acquired Telenet Group BVBA, formerly known as BASE Company NV ( BASE ), for a cash purchase price of €1,318.9 million ( $1,494.3 million at the transaction date) (the BASE Acquisition ). BASE is a mobile network operator in Belgium. Pro Forma Information The following unaudited pro forma condensed consolidated operating results give effect to the CWC Acquisition and the BASE Acquisition as if they had been completed as of January 1, 2015. No effect has been given to the CWC Carve-out Acquisition or the SFR BeLux Acquisition as the assumed completion of these acquisitions on January 1, 2016 would not have had a significant impact on our results of operations for the three and six months ended June 30, 2016. These pro forma amounts are not necessarily indicative of the operating results that would have occurred if these transactions had occurred on such date. The pro forma adjustments are based on certain assumptions that we believe are reasonable.

(b) Amounts include a related-party note receivable (the VodafoneZiggo JV Receivable ) with a principal amount of $1,141.3 million and $1,054.7 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 ( $114.1 million ) of principal to be paid annually during the first three years of the agreement, 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 three and six months ended June 30, 2017, interest accrued on the VodafoneZiggo JV Receivable was $15.8 million and $30.6 million , respectively, all of which has been cash settled. Equity Method Investments The following table sets forth the details of our share of losses of affiliates, net: Three months ended Six months ended 2017 2016 2017 2016 in millions VodafoneZiggo JV (a) $ 6.5 $ — $ 5.2 $ — Other (8.2 ) (27.2 ) (22.3 ) (55.1 ) Total $ (1.7 ) $ (27.2 ) $ (17.1 ) $ (55.1 ) _______________ (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 Ziggo Group Holding and its subsidiaries (including Liberty Global Netherlands Content B.V., referred to herein as “ Ziggo Sport ”) to VodafoneZiggo Group Holding B.V., a newly-formed entity that was formed as a 50 : 50 joint venture (the “ VodafoneZiggo JV ”) between Vodafone Group plc ( Vodafone ) and Liberty Global. Ziggo Sport , which became a subsidiary of Ziggo Group Holding during the fourth quarter of 2016, operates premium sports channels in the Netherlands. As a result of the formation of the VodafoneZiggo JV (the VodafoneZiggo JV Transaction ), effective December 31, 2016, we no longer consolidate Ziggo Group Holding . 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 Ziggo Group 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. At December 31, 2016, our right to receive this cash is reflected as a current receivable from the VodafoneZiggo JV in our condensed consolidated balance sheet. During the second quarter of 2017, the equalization payment amount was finalized, resulting in an additional €3.9 million ( $4.5 million at the transaction date) being received 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 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 first six months of 2017, we received a dividend distribution from the VodafoneZiggo JV of $87.3 million , which was accounted for as a return on capital for purposes of our condensed consolidated statement of cash flows. Pursuant to an agreement entered into in connection with the formation of the VodafoneZiggo JV Transaction (the Framework Agreement ), Liberty Global provides certain services to the VodafoneZiggo JV on a transitional or ongoing basis (collectively, the JV Services ). Pursuant to the terms of the Framework Agreement , the ongoing services will be provided for a period of four to six years depending on the type of service, while transitional services will be provided for a period of not less than 12 months, after which both parties shall be entitled to terminate the Framework Agreement based on specified notice periods. 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 . During the three and six months ended June 30, 2017 , we recorded revenue of $31.8 million and $63.3 million , respectively, related to the JV Services . In addition, at June 30, 2017 , $67.4 million was due from the VodafoneZiggo JV , primarily related to (a) services performed under the Framework Agreement and (b) amounts incurred by Liberty Global for certain equipment and licenses purchased on behalf of the VodafoneZiggo JV . This amount, which is periodically cash settled, is included in other current assets in our condensed consolidated balance sheet. The mobile and fixed-line operations of the VodafoneZiggo JV are experiencing significant competition. In particular, the mobile operations of the VodafoneZiggo JV continue to experience pressure on pricing, characterized by aggressive promotion campaigns, heavy marketing spend and increasing or unlimited data bundles. If the adverse impacts of economic, competitive, regulatory or other factors were to cause significant deterioration of the results of operations or cash flows of the VodafoneZiggo JV, 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 June 30, 2017 Six months ended June 30, 2017 in millions Revenue $ 1,096.5 $ 2,180.3 Loss before income taxes $ (25.6 ) $ (69.2 ) Net loss $ (18.1 ) $ (48.7 )

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In general, we seek to enter into derivative instruments to protect against (i) foreign currency movements, particularly with respect to borrowings that are denominated in a currency other than the functional currency of the borrowing entity, (ii) increases in the interest rates on our variable-rate debt 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 with respect to the U.S. dollar ( $ ), the euro ( € ), the British pound sterling ( £ ), the Swiss franc ( CHF ), the Chilean peso ( CLP ), the Czech koruna ( CZK ), the Hungarian forint ( HUF ), the Indian rupee ( INR ), the Jamaican dollar ( JMD ), the Philippine peso ( PHP ), 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.

(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 primary borrowing groups (as defined and described in note 8 ). 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 $72.2 million and ( $14.3 million ) during the three months ended June 30, 2017 and 2016 , respectively, and a net gain of $145.3 million and $7.1 million during the six months ended June 30, 2017 and 2016, 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 6 . (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 share collar (the Sumitomo Collar ) with respect to a portion of the shares of Sumitomo held by our company and (iii) the prepaid forward transaction (the Lionsgate Forward ) with respect to 2.5 million of the shares of Lionsgate held by our company. The fair values of the ITV Collar , the Sumitomo 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.

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 classification of these net cash outflows is as follows: Six months ended June 30, 2017 2016 in millions Operating activities: Liberty Global Group $ 112.4 $ (1.5 ) LiLAC Group (18.2 ) 2.8 Total operating activities 94.2 1.3 Investing activities: Liberty Global Group (0.5 ) — LiLAC Group (1.6 ) (0.4 ) Total investing activities (2.1 ) (0.4 ) Financing activities – Liberty Global Group (139.5 ) (43.3 ) Total cash inflows (outflows): Liberty Global Group (27.6 ) (44.8 ) LiLAC Group (19.8 ) 2.4 Total $ (47.4 ) $ (42.4 ) 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, 2017 , our exposure to counterparty credit risk included derivative assets with an aggregate fair value of $1,131.4 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 and 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, 2017 , 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 life of our cross-currency swap contracts at June 30, 2017 : 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 5.5 $ 8,933.0 £ 5,844.3 (a) (b) 6.2 £ 30.3 $ 50.0 (a) 2.3 UPC Holding $ 2,390.0 € 1,973.7 6.4 € 379.2 $ 425.0 (a) 7.2 $ 1,000.0 CHF 922.0 (b) 6.6 € 2,415.2 CHF 2,781.0 5.6 € 418.5 CZK 11,521.8 3.0 € 488.0 HUF 138,437.5 4.5 € 851.6 PLN 3,604.5 4.2 € 225.9 RON 650.0 4.6 Unitymedia $ 3,305.0 € 2,562.1 (b) 6.2 € 89.4 $ 100.0 5.5 Telenet $ 2,300.0 € 2,067.6 7.6 € 520.1 $ 595.0 (a) 7.0 CWC $ 108.3 JMD 13,817.5 5.5 £ 146.7 $ 194.3 1.7 VTR Finance $ 1,400.0 CLP 951,390.0 4.8 _______________ (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 interest-related payments and receipts. At June 30, 2017 , the total U.S. dollar equivalents of the notional amounts of these derivative instruments for the Virgin Media , UPC Holding and Telenet borrowing groups were $514.4 million , $432.8 million and $593.5 million , respectively. (b) Includes certain derivative instruments that are “forward-starting,” such that the initial exchange occurs at a date subsequent to June 30, 2017 . These instruments are typically entered into in order to extend existing hedges without the need to amend existing contracts. Interest Rate Derivative Contracts As noted above, we enter into interest rate swaps to protect against increases in the interest rates on our variable-rate debt. Pursuant to these derivative instruments, we typically pay fixed interest rates and receive variable interest rates on specified notional amounts. The following table sets forth the total U.S. dollar equivalents of the notional amounts and the related weighted average remaining contractual life of our interest rate swap contracts at June 30, 2017 : Borrowing group Notional amount due from counterparty Weighted average remaining life in millions in years Virgin Media (a) $ 8,492.7 5.1 UPC Holding (a) $ 4,930.2 6.2 Unitymedia $ 306.1 5.5 Telenet (a) $ 6,144.7 5.7 CWC (a) $ 2,225.0 6.6 Liberty Puerto Rico $ 675.0 3.8 _______________ (a) Includes forward-starting derivative instruments. 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 life of our basis swap contracts at June 30, 2017 : Borrowing group Notional amount due from counterparty Weighted average remaining life in millions in years Virgin Media $ 4,525.1 0.5 UPC Holding (a) $ 4,300.0 1.0 Unitymedia (a) $ 855.0 1.2 Telenet (a) $ 4,100.0 1.0 CWC (a) $ 2,225.0 1.0 _______________ (a) Includes forward-starting derivative instruments. 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, 2017 , the total U.S. dollar equivalents of the notional amounts of our interest rate caps and collars were $1,246.5 million and $1,295.4 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: Increase (decrease) to borrowing costs at June 30, 2017 (a) Liberty Global Group borrowing groups (0.03 )% Virgin Media 0.07 % Telenet (0.34 )% Unitymedia (0.27 )% UPC Holding 0.33 % LiLAC Group borrowing groups 0.30 % CWC 0.47 % VTR Finance (0.52 )% Liberty Puerto Rico 0.86 % _______________ (a) Represents the effect of derivative instruments in effect at June 30, 2017 and does not include forward-starting derivative instruments. 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, 2017 , the total U.S. dollar equivalents of the notional amount of foreign currency forward and option contracts was $1,436.5 million . Equity-related Derivatives On May 22, 2017, we settled the third tranches of the Sumitomo Collar ( $51.0 million asset on the settlement date) and related borrowings (the Sumitomo Collar Loan ) ( $169.9 million liability on the settlement date) with shares of Sumitomo that were borrowed pursuant to a securities lending arrangement (the Sumitomo Share Loan ). The aggregate market value of the borrowed Sumitomo shares on the transaction date was $117.4 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 Sumitomo Share Loan . The reported fair values of these investments and instruments as of June 30, 2017 likely will not represent the value that will be paid or received upon the ultimate settlement or disposition of these assets and liabilities. In the case of the investments that we account for using the fair value method, the values we realize upon disposition will be dependent upon, among other factors, market conditions and the forecasted financial performance of the investees at the time of any such disposition. With respect to our derivative and certain debt instruments, we expect that the values realized generally will be based on market conditions at the time of settlement, which may occur at the maturity of the derivative instrument or at the time of the repayment or refinancing of the underlying debt instrument. 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 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. Effective January 1, 2017, we incorporated a Monte Carlo based approach into our calculation of the value assigned to the risk that we or our counterparties will default on our respective derivative obligations. Previously, we used a static calculation derived from our most current mark-to-market valuation to calculate the impact of counterparty credit risk. The adoption of a Monte Carlo based approach did not have a material impact on the overall fair value of our derivative instruments. Our credit risk valuation adjustments with respect to our cross-currency and interest rate swaps are quantified and further explained in note 5 . Fair value measurements are also used in connection with nonrecurring valuations performed in connection with impairment assessments, acquisition accounting and the accounting for our initial investment in the VodafoneZiggo JV . These nonrecurring valuations include the valuation of reporting units, customer relationship and other intangible assets, property and equipment, the implied value of goodwill and the valuation of our initial investment in the VodafoneZiggo JV . The valuation of private reporting units and our initial investment in the VodafoneZiggo JV 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. The implied value of goodwill is determined by allocating the fair value of a reporting unit to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination, with the residual amount allocated to goodwill. All of our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy. The weighted average discount rates used in the final valuation of the customer relationships acquired as a result of the CWC Acquisition ranged from 9.0% to 12.0% . 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, 2017 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 $ 1,999.5 $ — $ 1,999.5 $ — Equity-related derivative instruments 556.6 — — 556.6 Foreign currency forward and option contracts 24.1 — 24.1 — Other 0.9 — 0.9 — Total derivative instruments 2,581.1 — 2,024.5 556.6 Investments 2,070.2 1,670.8 — 399.4 Total assets $ 4,651.3 $ 1,670.8 $ 2,024.5 $ 956.0 Liabilities: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,414.2 $ — $ 1,399.2 $ 15.0 Equity-related derivative instruments 8.8 — — 8.8 Foreign currency forward and option contracts 19.2 — 19.2 — Total derivative liabilities 1,442.2 — 1,418.4 23.8 Debt 757.3 356.8 400.5 — Total liabilities $ 2,199.5 $ 356.8 $ 1,818.9 $ 23.8 Fair value measurements at December 31, 2016 using: Description December 31, 2016 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 $ 2,606.5 $ — $ 2,606.5 $ — Equity-related derivative instruments 524.0 — — 524.0 Foreign currency forward and option contracts 45.1 — 45.1 — Other 0.5 — 0.5 — Total derivative instruments 3,176.1 — 2,652.1 524.0 Investments 2,057.2 1,682.4 — 374.8 Total assets $ 5,233.3 $ 1,682.4 $ 2,652.1 $ 898.8 Liabilities: Derivative instruments: Cross-currency and interest rate derivative contracts $ 1,292.2 $ — $ 1,281.5 $ 10.7 Equity-related derivative instruments 8.6 — — 8.6 Foreign currency forward and option contracts 9.0 — 9.0 — Other 0.1 — 0.1 — Total derivative instruments 1,309.9 — 1,290.6 19.3 Debt 344.4 215.5 128.9 — Total liabilities $ 1,654.3 $ 215.5 $ 1,419.5 $ 19.3 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 asset (liability) at January 1, 2017 $ 374.8 $ (10.7 ) $ 515.4 $ 879.5 Gains included in net loss (a): Realized and unrealized gains (losses) on derivative instruments, net — (4.3 ) 81.5 77.2 Realized and unrealized gains due to changes in fair values of certain investments and debt, net 21.3 — — 21.3 Partial settlement of Sumitomo Collar (b) — — (51.0 ) (51.0 ) Additions 12.7 — — 12.7 Foreign currency translation adjustments, dividends and other, net (9.4 ) — 1.9 (7.5 ) Balance of net asset (liability) at June 30, 2017 $ 399.4 $ (15.0 ) $ 547.8 $ 932.2 _______________ (a) Most of these net gains relate to assets and liabilities that we continue to carry on our condensed consolidated balance sheet as of June 30, 2017 .

Based on the results of our October 1, 2016 goodwill impairment test, a hypothetical decline of 20% or more in the fair value of any of CWC’s reporting units could result in the need to record a goodwill impairment charge. If, among other factors, (i) the equity values of the LiLAC Group were to decline or (ii) the adverse impacts of economic, competitive, regulatory or other factors were to cause CWC’s results of operations or cash flows to be worse than anticipated, we could conclude in future periods that impairment charges are required in order to reduce the carrying values of our goodwill and, to a lesser extent, other long-lived assets.

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 financing costs, our weighted average interest rate on our aggregate variable- and fixed-rate indebtedness was 4.77% (including 4.50% for the Liberty Global Group and 6.43% for the LiLAC Group ) at June 30, 2017 . For information regarding our derivative instruments, see note 5 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at June 30, 2017 without regard to covenant compliance calculations or other conditions precedent to borrowing. At June 30, 2017 , based on the applicable leverage-based restricted payment tests and leverage covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, and 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 (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 assume no changes from June 30, 2017 borrowing levels and are based on the applicable leverage-based restricted payment tests and covenant and other limitations in effect for each borrowing group at June 30, 2017 , both before and after considering the impact of the completion of the June 30, 2017 compliance requirements. For information regarding certain refinancing transactions completed subsequent to June 30, 2017 that could have an impact on unused borrowing capacity and/or the availability to be borrowed, loaned or distributed, see note 16 .

(2) Amounts include the impact of (i) the July 3, 2017 drawdown of $50.0 million under the CWC Revolving Credit Facility to fund a portion of the contribution to the CWSF (as defined in note 14 ) and (ii) the removal of the limitation related to letters of credit issued in connection with certain pension obligations. For additional information, see note 14 . (3) Borrowing currency represents the euro equivalent of the total Unitymedia Credit Facilities . (c) The estimated fair values of our debt instruments are 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 6 .

The net proceeds from the April 2027 VM Senior Secured Notes were used to redeem in full the £640.0 million ( $832.5 million ) outstanding principal amount under the April 2021 VM Sterling Senior Secured Notes . In connection with these transactions, Virgin Media recognized a loss on debt modification and extinguishment, net, of $39.9 million .

The Exchange Offer was consummated on March 21, 2017 and £521.3 million ( $678.1 million ) aggregate principal amount of the January 2021 VM Sterling Senior Secured Notes was exchanged for £521.3 million aggregate principal amount of the 2025 VM Sterling Senior Secured Notes . Interest on the 2025 VM Sterling Senior Secured Notes will initially accrue at a rate of 6.0% up to January 15, 2021 and at a rate of 11.0% thereafter. The January 2021 VM Sterling Senior Secured Notes were exchanged for the 2025 VM Sterling Senior Secured Notes in a non-cash transaction, other than the payment of accrued and unpaid interest on the exchanged January 2021 VM Sterling Senior Secured Notes . In connection with these transactions, Virgin Media recognized a gain on debt modification and extinguishment, net, of $5.7 million . This gain includes (i) the write-off of $7.0 million of unamortized premium and (ii) the payment of $1.3 million of third-party costs. Subject to the circumstances described below, the 2025 VM Sterling Senior Secured Notes are non-callable until January 15, 2021. At any time prior to January 15, 2021, Virgin Media may redeem some or all of the 2025 VM Sterling Senior Secured Notes by paying a “make-whole” premium, which is the present value of all remaining scheduled interest payments to January 15, 2021 using the discount rate (as specified in the indenture) as of the redemption date plus 50 basis points .

UPCB Finance VII is a special purpose financing entity, which is 100% owned by a third party, created for the primary purpose of facilitating the offering of senior secured notes, for which we are the primary beneficiary. As such, UPC Holding and Liberty Global are required to consolidate UPCB Finance VII . UPCB Finance VII used the proceeds to fund UPC Facility AQ , an additional facility under the UPC Holding Bank Facility , with a subsidiary of UPC Holding as the borrower. The call provisions, maturity and applicable interest rate for UPC Facility AQ are the same as those for the UPCB Finance VII Notes .

Income Taxes	Income Taxes Income tax expense attributable to our earnings (loss) 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, 2017 2016 2017 2016 in millions Computed “expected” tax benefit (expense) (a) $ 100.6 $ (33.0 ) $ 123.8 $ 51.3 Change in valuation allowances (b): Expense (125.8 ) (1.5 ) (207.7 ) (235.1 ) Benefit 11.6 (119.8 ) 35.4 13.9 Non-deductible or non-taxable foreign currency exchange results (b): Expense (116.1 ) (1.0 ) (174.6 ) (2.3 ) Benefit 2.4 103.5 4.3 122.1 Non-deductible or non-taxable interest and other items (b): Expense (29.5 ) (23.1 ) (99.2 ) (45.2 ) Benefit 10.9 12.0 24.0 21.9 International rate differences (b) (c): Benefit 43.2 41.8 79.0 77.0 Expense (14.9 ) (16.4 ) (46.6 ) (23.0 ) Basis and other differences in the treatment of items associated with investments in subsidiaries and affiliates (b): Expense (14.0 ) (73.4 ) (28.0 ) (97.1 ) Benefit 2.2 7.5 2.6 18.8 Enacted tax law and rate change 6.7 (1.0 ) 16.4 (5.2 ) Recognition of previously unrecognized tax benefits 5.3 2.9 8.9 17.9 Tax effect of intercompany financing — 47.0 — 85.1 Other, net (12.3 ) (1.5 ) (14.8 ) (7.2 ) Total income tax expense $ (129.7 ) $ (56.0 ) $ (276.5 ) $ (7.1 ) _______________ (a) The statutory or “expected” tax rates are U.K. rates of 19.25% for the 2017 periods and 20.0% for the 2016 periods. The statutory rate for the 2017 periods represents the blended rate that will be 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 is in effect for the remainder of 2017. (b) Country jurisdictions giving rise to income tax benefits are grouped together and shown separately from country jurisdictions giving rise to income tax expenses. (c) Amounts reflect adjustments (either a benefit or an expense) to the “expected” tax benefit (expense) for statutory rates in jurisdictions in which we operate outside of the U.K. At June 30, 2017 , our unrecognized tax benefits of $566.1 million included $508.7 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, 2017 . 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 Austria, Chile, Germany, the Netherlands, Panama, Poland, Trinidad and Tobago, the U.S. and certain other jurisdictions within Latin America and the Caribbean. 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. , we have received notices of adjustment from the Internal Revenue Service with respect to our 2009 and 2010 income tax returns, and have entered into the appeals process with respect to the 2009 and 2010 matters. In Chile, adjustments received from the tax authorities for the tax years 2011 and 2012 are in dispute. We have appealed these adjustments to the Chilean tax court. Also in Chile, we recorded an income tax receivable in connection with the expected utilization of certain net operating loss carryforwards upon the completion of a merger transaction of two indirect subsidiaries of Liberty Global . We are engaged in an ongoing examination by tax authorities in Chile in connection with this receivable and were notified during the third quarter of 2016 that approximately 48%

Earnings Per Share [Abstract]
Earnings or Loss per Share	Earnings or Loss per Share Basic earnings or loss per shares ( 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, PSAR s, RSU s and convertible securities) as if they had been exercised, vested or converted at the beginning of the periods presented. The details of our net earnings (loss) attributable to holders of Liberty Global Shares and LiLAC Shares are set forth below: Three months ended Six months ended June 30, June 30, 2017 2016 2017 2016 in millions Net earnings (loss) attributable to holders of: Liberty Global Shares $ (636.6 ) $ 204.2 $ (929.5 ) $ (126.4 ) LiLAC Shares (37.7 ) (102.8 ) (65.0 ) (141.3 ) Net earnings (loss) attributable to Liberty Global shareholders $ (674.3 ) $ 101.4 $ (994.5 ) $ (267.7 ) The details of our weighted average ordinary shares outstanding are set forth below: Three months ended Six months ended June 30, June 30, 2017 2016 2017 2016 Weighted average ordinary shares outstanding: Liberty Global Shares: Basic 853,612,217 892,530,351 871,936,668 868,011,483 Diluted 853,612,217 900,686,305 871,936,668 868,011,483 LiLAC Shares: Basic 172,074,934 50,357,803 172,410,613 47,145,780 Diluted 172,074,934 50,357,803 172,410,613 47,145,780 Liberty Global Shares We reported losses attributable to holders of Liberty Global Shares for the three and six months ended June 30, 2017 and the six months ended June 30, 2016 . Therefore, the potentially dilutive effect at June 30, 2017 and 2016 of the following items were not included in the computation of diluted loss per share attributable to holders of Liberty Global Shares because their inclusion would have been anti-dilutive to the computation or, in the case of certain PSU s and, at June 30, 2016 , PGUs , because such awards had not yet met the applicable performance criteria: (i) the aggregate number of outstanding options, SAR s, PSAR s and RSU s of approximately 55.5 million and 49.3 million , respectively, (ii) the aggregate number of PSU s and PGUs of approximately 7.3 million and 8.9 million , respectively, and (iii) the aggregate number of shares issuable pursuant to obligations that may be settled in cash or shares of nil and approximately 2.7 million , respectively. The details of the calculation of EPS with respect to Liberty Global Shares for the three months ended June 30, 2016 are set forth in the following table: Numerator: Net earnings attributable to holders of Liberty Global Shares (basic and diluted EPS computation) (in millions) $ 204.2 Denominator: Weighted average ordinary shares (basic EPS computation) 892,530,351 Incremental shares attributable to the assumed exercise of outstanding options, SARs and PSARs and the release of share units upon vesting (treasury stock method) 8,155,954 Weighted average ordinary shares (diluted EPS computation) 900,686,305 The following were excluded from the calculation of diluted earnings per share set forth in the table above because their effect would have been anti-dilutive: (i) a total of 24.3 million options, SAR s, PSAR s and RSU s and (ii) 2.7 million shares that were issuable upon the conversion of certain convertible notes of Virgin Media . LiLAC Shares We reported losses attributable to holders of LiLAC Shares for the three and six months ended June 30, 2017 and 2016 . Therefore, the potentially dilutive effect at June 30, 2017 and 2016 of the following items were not included in the computation of diluted loss per share attributable to holders of LiLAC Shares because their inclusion would have been anti-dilutive to the computation or, in the case of certain PSU s and, at June 30, 2016 , PGUs , because such awards had not yet met the applicable performance criteria: (i) the aggregate number of shares issuable pursuant to outstanding options, SAR s, PSAR s and RSU s of approximately 9.1 million and 1.8 million , respectively, and (ii) the aggregate number of shares issuable pursuant to PSU s and PGUs of approximately 1.3 million and 0.4 million

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments In the normal course of business, we have entered into agreements that commit our company to make cash payments in future periods with respect to network and connectivity commitments, programming contracts, purchases of customer premises and other equipment and services, non-cancellable operating leases and other items. The following table sets forth the U.S. dollar equivalents of such commitments as of June 30, 2017 : Payments due during: Remainder 2018 2019 2020 2021 2022 Thereafter Total in millions Network and connectivity commitments $ 773.7 $ 448.6 $ 364.7 $ 276.0 $ 251.2 $ 69.3 $ 887.7 $ 3,071.2 Programming commitments 622.1 1,093.5 600.8 244.2 74.5 37.6 61.4 2,734.1 Purchase commitments 900.2 292.6 242.3 176.9 83.4 22.6 62.2 1,780.2 Operating leases 75.0 120.6 100.9 80.7 65.8 54.6 214.4 712.0 Other commitments 48.9 24.1 14.1 8.8 8.0 8.0 7.5 119.4 Total (a) $ 2,419.9 $ 1,979.4 $ 1,322.8 $ 786.6 $ 482.9 $ 192.1 $ 1,233.2 $ 8,416.9 _______________ (a) The commitments included in this table do not reflect any liabilities that are included in our June 30, 2017 condensed consolidated balance sheet. 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. 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. In addition, 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 $1,075.4 million (including $870.4 million for the Liberty Global Group and $205.0 million for the LiLAC Group ) and $1,249.6 million (including $1,104.7 million for the Liberty Global Group and $144.9 million for the LiLAC Group ) during the six months ended June 30, 2017 and 2016 , respectively. 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. Commitments arising from acquisition agreements are not reflected in the above table. For information regarding our commitments under an acquisition agreement, see note 3 . 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, 2017 and 2016 , see note 5 . 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. In addition, CWC has provided indemnifications of (a) up to $300.0 million in respect of any potential tax-related claims related to the disposal of CWC ’s interests in certain businesses in April 2013 and (b) an unlimited amount of qualifying claims associated with the disposal of another business in May 2014. The first indemnification expires in April 2020 and the second expires in May 2020. We do not expect that either of these arrangements will require us to make material payments to the indemnified parties. The CWC Acquisition constituted a “change of control” under a contingent funding agreement (the Contingent Funding Agreement ) between CWC and the trustee of the Cable & Wireless Superannuation Fund ( CWSF ). Under the terms of the Contingent Funding Agreement , the change in control provided the trustee of the CWSF with the right to satisfy certain funding requirements of the CWSF through the utilization of letters of credit aggregating £100.0 million that were put in place in connection with a previous acquisition made by CWC . On June 26, 2017, the trustee of the CWSF elected to drawdown the full £100.0 million ( $129.6 million at the applicable rate) available under the letters of credit, which amount was contributed to the CWSF on July 3, 2017. Taking into account the aforementioned £100.0 million contribution and based on the triennial valuation that was completed in July 2017, no funding deficit exists with respect to the CWSF . As a result, we do not expect to make material contributions to the CWSF through April 2019. 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 should the 2008 PICs Agreement not be rescinded. 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 ). Telenet intends to defend itself vigorously in the resumed proceedings and does not expect an outcome before the end of 2017. 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 ( $22.8 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. Deutsche Telekom Litigation. On December 28, 2012, Unitymedia filed a lawsuit against Telekom Deutschland GmbH ( Deutsche Telekom ), an operating subsidiary of Deutsche Telekom AG, in which Unitymedia asserts that it pays excessive prices for the co-use of Deutsche Telekom ’s cable ducts in Unitymedia ’s footprint. The Federal Network Agency approved rates for the co-use of certain ducts of Deutsche Telekom in March 2011. Based in part on these approved rates, Unitymedia is seeking a reduction of the annual lease fees (approximately €76 million ( $87 million ) for 2012) by approximately two-thirds and 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. We have appealed this decision, however, 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. Belgium Regulatory Developments. In December 2010, the Belgisch Instituut voor Post en Telecommunicatie and the regional regulators for the media sectors (together, the Belgium Regulatory Authorities ) published their respective draft decisions reflecting the results of their joint analysis of the broadcasting market in Belgium. The Belgium Regulatory Authorities adopted a final decision on July 1, 2011 (the July 2011 Decision ) with some minor revisions. The regulatory obligations imposed by the July 2011 Decision include (i) an obligation to make a resale offer at “retail minus’’ of the cable analog package available to third-party operators (including Proximus ), (ii) an obligation to grant third-party operators (except Proximus ) access to digital television platforms (including the basic digital video package) at “retail minus” and (iii) an obligation to make a resale offer at “retail minus’’ of broadband internet access available to beneficiaries of the digital television access obligation that wish to offer bundles of digital video and broadband internet services to their customers (except Proximus ). In February 2012, Telenet submitted draft reference offers regarding the obligations described above, and the Belgium Regulatory Authorities published the final decision on September 9, 2013. Telenet has implemented the access obligations as described in its reference offers and, on March 1, 2016, Orange Belgium NV ( Orange Belgium ), formerly known as Mobistar SA, launched a commercial offer combining a cable TV package and broadband internet access for certain of their mobile customers. In addition, as a result of the November 2014 decision by the Brussels Court of Appeal described below, on November 14, 2014, Proximus submitted a request to Telenet to commence access negotiations. Telenet contests this request and has asked the Belgium Regulatory Authorities to assess the reasonableness of the Proximus request. The timing for a decision regarding this assessment by the Belgium Regulatory Authorities is not known. On December 14, 2015, the Belgium Regulatory Authorities published a draft decision, which amended previously-issued decisions and sets forth the “retail minus” tariffs of minus 26% for basic television (basic analog and digital video package) and minus 18% for the bundle of basic television and broadband internet services during an initial two -year period. Following this two -year period, the tariffs would change to minus 15% and 7% , respectively. The draft decision was notified to the European Commission and a final decision was adopted on February 19, 2016. A “retail minus” method of pricing involves a wholesale tariff calculated as the retail price for the offered service by Telenet , excluding VAT and copyrights, and further deducting the retail costs avoided by offering the wholesale service (such as costs for billing, franchise, consumer service, marketing and sales). Telenet filed an appeal against the July 2011 Decision with the Brussels Court of Appeal. On November 12, 2014, the Brussels Court of Appeal rejected Telenet ’s appeal of the July 2011 Decision and accepted Proximus ’s claim that Proximus should be allowed access to Telenet ’s, among other operators, digital television platform and the resale of bundles of digital video and broadband internet services. On November 30, 2015, Telenet filed an appeal of this decision with the Belgian Supreme Court . In 2014, Telenet and wireless operator Orange Belgium each filed an appeal with the Brussels Court of Appeal against the initial retail minus decisions. These appeals are still pending. On April 25, 2016, Telenet also filed an appeal with the Brussels Court of Appeal challenging the February 19, 2016 retail minus decision. There can be no certainty that Telenet ’s appeals will be successful. On July 7, 2017, the Belgium Regulatory Authorities published draft market review decisions for public consultation regarding the regulation of the wholesale broadband and broadcasting markets (the July 2017 Draft Market Review Decisions ). The July 2017 Draft Market Review Decisions include proposals regarding the following regulatory obligations (based on "reasonable tariffs") on cable operators within their respective footprints: (i) an obligation to grant third-party operators access to digital television platforms (including the basic digital video package and analogue TV) and separately (ii) an obligation to make a bitstream offer of broadband internet access available (including fixed voice as an option). The Belgium Regulatory Authorities also propose the continuation of access regulation to Proximus for digital subscriber lines ( DSL ), adding access to fiber-to-the-home ( FTTH ) and multicast. DSL would continue to be regulated on cost orientation, while FTTH would be regulated at "reasonable tariffs". The public consultation runs until September 15, 2017, followed by a notification to the European Commission for advice by the end of 2017. If the July 2017 Draft Market Review Decisions are adopted, they will replace the July 2011 Decision . However, Telenet has serious concerns with these proposals as they would lead to regulating two broadband infrastructures, which is inconsistent with the European Single Market Strategy to stimulate further investments in broadband networks. Telenet is currently preparing its submission to the public consultation. The July 2011 Decision and the July 2017 Draft Market Review Decisions aim to, and in their 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 growth in the 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 ultimately afforded to Telenet ’s network and other competitive factors or market developments. Financial Transactions Tax. Certain countries in the European Union ( E.U. ), including Germany, Austria and Slovakia, are participating in an enhanced cooperation procedure to introduce a financial transactions tax (the FTT ). Under the draft language of the FTT proposal, a wide range of financial transactions could be taxed at rates of at least 0.01% for derivative transactions based on the notional amount and 0.1% for other covered financial transactions based on the underlying transaction price. Each of the individual countries would be permitted to determine an exact rate, which could be higher than the proposed rates of 0.01% and 0.1% . Any implementation of the FTT could have a global impact because it would apply to all financial transactions where a financial institution is involved (including unregulated entities that engage in certain types of covered activity) and either of the parties (whether the financial institution or its counterparty) is in one of the participating countries. Although there continues to be ongoing discussions in the relevant countries around the FTT , uncertainty remains as to if and when the FTT will be implemented and the breadth of its application. Based on our understanding of the current status of the potential FTT , we do not expect that any implementation of the FTT would occur before 2018. Any imposition of the FTT could increase banking fees and introduce taxes on internal transactions that we currently perform. Due to the uncertainty regarding the FTT , we are currently unable to estimate the financial impact that the FTT could have on our results of operations, cash flows or financial position. 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 £46.7 million ( $60.7 million ) as of June 30, 2017 . 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. This matter will likely be subject to court proceedings that could delay the ultimate resolution for an extended period of time. No portion of this potential exposure has been accrued by our company as the likelihood of loss is not considered to be probable. Hungary VAT Matter. In February 2016, our direct-to-home satellite ( DTH ) operations in Luxembourg received a second instance decision from the Hungarian tax authorities as a result of an audit with respect to VAT payments that the Hungarian tax authorities conducted for the years 2010 through 2012. The Hungarian tax authorities assessed our DTH operations with an obligation to pay VAT for the years audited of HUF 5,413.2 million ( $20.0 million ), excluding interest and penalties, which could be significant. We believe that our DTH operations have operated in compliance with all applicable rules, regulations and interpretations thereof, including a binding tax ruling that we received from the Hungarian government in 2010. In October 2016 a Budapest court disagreed with the tax authorities and dismissed the assessment. On February 2, 2017, the Hungarian tax authorities appealed the Budapest court decision to the Hungarian Supreme Court and a hearing has been scheduled for November 9, 2017. No portion of this exposure has been accrued by us as the likelihood of loss is not considered to be probable. 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, will result in significant increases in our network infrastructure charges. We estimate that the aggregate amount of these increases will be approximately £30 million ( $39 million ) during 2017 and will build to a maximum aggregate increase of up to £100 million ( $130 million ) in 2021. 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 segments for which discrete financial information is regularly reviewed by our chief operating decision maker and (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 operating income before depreciation and amortization ( Adjusted OIBDA ) is the primary measure used by our chief operating decision maker to evaluate segment operating performance. Adjusted OIBDA 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. As of June 30, 2017 , our reportable segments were as follows: Consolidated: • European Division : • U.K./Ireland • Germany • Belgium • Switzerland/Austria • Central and Eastern Europe • LiLAC Division: • CWC • Chile • Puerto Rico Nonconsolidated: • VodafoneZiggo JV On December 31, 2016, we completed the VodafoneZiggo JV Transaction , whereby we contributed Ziggo Group Holding (including Ziggo Sport ) to the VodafoneZiggo JV . In our segment presentation for the three and six months ended June 30, 2016, Ziggo Group Holding is separately reported as “ The Netherlands ” and Ziggo Sport is included in our “ Corporate and Other ” category. Effective January 1, 2017, following the closing of the VodafoneZiggo JV Transaction , we have identified the VodafoneZiggo JV as a nonconsolidated reportable segment. Our investment in the VodafoneZiggo JV is attributed to the Liberty Global Group . For additional information regarding the VodafoneZiggo JV Transaction , see note 4 . All of the reportable segments set forth above derive their revenue primarily from residential and B2B communications services, including video, broadband internet and fixed-line telephony services and, with the exception of Puerto Rico, mobile services. At June 30, 2017 , our operations in the European Division provided residential and B2B communications services in 11 European countries and DTH services to customers in the Czech Republic, Hungary, Romania and Slovakia through a Luxembourg-based organization that we refer to as “ UPC DTH .” In addition to UPC DTH , our Central and Eastern Europe segment includes our broadband communications operations in the Czech Republic, Hungary, Poland, Romania and Slovakia. The European Division ’s central and other category includes (i) costs associated with certain centralized functions, including billing systems, network operations, technology, marketing, facilities, finance and other administrative functions, and (ii) intersegment eliminations within the European Division . In addition, our LiLAC Division provides residential and B2B communications services in (a) 18 countries, all but one of which are located in Latin America and the Caribbean, through CWC , (b) Chile through VTR and (c) Puerto Rico through Liberty Puerto Rico . CWC also provides (1) B2B communications services in certain other countries in Latin America and the Caribbean and (2) wholesale communications services over its sub-sea and terrestrial networks that connect over 40 markets in that region. The corporate and other category for the Liberty Global Group includes the Liberty Global Group ’s corporate operations and less significant consolidated operating segments that provide programming and other services, including Ziggo Sport through December 31, 2016. 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 , Liberty Puerto Rico and certain subsidiaries of CWC that are not wholly owned, we consolidate 100% of the revenue and expenses of these entities in our condensed consolidated statements of operations despite the fact that third parties own significant interests in these entities. The noncontrolling owners’ interests in the operating results of Telenet , Liberty Puerto Rico , certain subsidiaries of CWC 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.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes In March 2016, the Financial Accounting Standards Board ( FASB ) issued Accounting Standards Update ( ASU ) No. 2016-09, Compensation — Stock Compensation, Improvements to Employee Share-Based Payment Accounting ( ASU 2016-09 ), which simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification within the statement of cash flows. We adopted ASU 2016-09 on January 1, 2017. As a result of adopting this standard, we (i) recognized a cumulative effect adjustment to our accumulated deficit as of January 1, 2017 and (ii) retrospectively revised the presentation of our condensed consolidated statements of cash flows to remove the operating cash outflows and financing cash inflows associated with excess tax benefits from share-based compensation. The cumulative effect adjustment, which totaled $15.3 million , represents the tax effect of deductions in excess of the financial reporting expense for share-based compensation that were not previously recognized for financial reporting purposes as these tax benefits were not realized as a reduction of income taxes payable. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment ( ASU 2017-04 ), which eliminates the requirement to estimate the implied fair value of a reporting unit’s goodwill as determined following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, a company should recognize any goodwill impairment by comparing the fair value of a reporting unit to its carrying amount. We early-adopted ASU 2017-04 effective January 1, 2017. The adoption of ASU 2017-04 , which reduces the complexity surrounding the evaluation of our goodwill for impairment, had no immediate impact on our impairment evaluations. Recent Accounting Pronouncements ASU 2014-09 In May 2014, the FASB issued 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 promised goods or services to customers. ASU 2014-09 , as amended by ASU No. 2015-14, will replace existing revenue recognition guidance when it becomes effective for annual and interim reporting periods beginning after December 15, 2017. This new standard permits the use of either the retrospective or cumulative effect transition method. We will adopt ASU 2014-09 effective January 1, 2018 using the cumulative effect transition method. While we are continuing to evaluate the effect that ASU 2014-09 will have on our consolidated financial statements, we have identified a number of our current revenue recognition policies that will be impacted by ASU 2014-09 , including the accounting for (i) time-limited discounts and free service periods provided to our customers and (ii) certain up-front fees charged to our customers. These impacts are discussed below: • When we enter into contracts to provide services to our customers, we often provide time-limited discounts or free service periods. Under current accounting rules, we recognize revenue net of discounts during the promotional periods and do not recognize any revenue during free service periods. Under ASU 2014-09 , revenue recognition will be accelerated for these contracts as the impact of the discount or free service period will be recognized uniformly over the total contractual period. • When we enter into contracts to provide services to our customers, we often charge installation or other up-front fees. Under current accounting rules, installation fees related to services provided over our cable networks are recognized as revenue during the period in which the installation occurs to the extent these fees are equal to or less than direct selling costs. Under ASU 2014-09 , these fees will generally be deferred and recognized as revenue over the contractual period, or longer if the up-front fee results in a material renewal right. As the above revenue recognition changes have offsetting impacts and both result in a relatively minor shift in the timing of revenue recognition, we currently do not expect ASU 2014-09 to have a material impact on our consolidated revenue. ASU 2014-09 will also impact our accounting for certain upfront costs directly associated with obtaining and fulfilling customer contracts. Under our current policy, these costs are expensed as incurred unless the costs are in the scope of another accounting topic that allows for capitalization. Under ASU 2014-09 , the upfront costs that are currently expensed as incurred will be recognized as assets and amortized to other operating expenses over a period that is consistent with the transfer to the customers of the goods or services to which the assets relate, which we have generally interpreted to be the expected life of the customer relationship. The impact of the accounting change for these costs will be dependent on numerous factors, including the number of new subscriber contracts added in any given period, but we expect the adoption of this accounting change will initially result in the deferral of a significant amount of operating and selling costs. The ultimate impact of adopting ASU 2014-09 for both revenue recognition and costs to obtain and fulfill contracts will depend on the promotions and offers in place during the period leading up to and after the adoption of ASU 2014-09 . 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 lease assets and lease liabilities on the balance sheet with additional disclosures about leasing arrangements. ASU 2016-02 requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach also includes a number of optional practical expedients an entity may elect to apply. 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. 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 lease assets and lease liabilities in our consolidated balance sheets for those leases classified as operating leases under previous U.S. GAAP . ASU 2016-02 will not have significant impacts on our consolidated statements of operations or cash flows. 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 will 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 computation, which can include credits, within non-operating income (expense) in our consolidated statements of operations. ASU 2017-07 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted for interim or annual periods.

Schedule of Recognized Identified Assets Acquired and Liabilities Assumed	A summary of the purchase price and the opening balance sheet of CWC at the May 16, 2016 acquisition date is presented in the following table. The opening balance sheet presented below reflects our final purchase price allocation (in millions): Cash and cash equivalents $ 210.8 Other current assets 578.5 Property and equipment, net 2,914.2 Goodwill (a) 5,344.3 Intangible assets subject to amortization, net (b) 1,416.0 Other assets, net 577.8 Current portion of debt and capital lease obligations (94.1 ) Other accrued and current liabilities (753.2 ) Long-term debt and capital lease obligations (3,305.4 ) Other long-term liabilities (751.8 ) Noncontrolling interests (c) (1,453.2 ) Total purchase price (d) $ 4,683.9 _______________ (a) The goodwill recognized in connection with the CWC Acquisition is primarily attributable to (i) the ability to take advantage of CWC ’s existing terrestrial and sub-sea networks to gain immediate access to potential customers and (ii) synergies that are expected to be achieved through the integration of CWC with other operations in the LiLAC Group . (b) Amount primarily includes intangible assets related to customer relationships. The weighted average useful life of CWC ’s intangible assets at the May 16, 2016 acquisition date was approximately nine years . (c) Represents the estimated aggregate fair value of the noncontrolling interests in CWC ’s subsidiaries as of May 16, 2016 .

Pro Forma Information for Significant Acquisitions	The following unaudited pro forma condensed consolidated operating results give effect to the CWC Acquisition and the BASE Acquisition as if they had been completed as of January 1, 2015. No effect has been given to the CWC Carve-out Acquisition or the SFR BeLux Acquisition as the assumed completion of these acquisitions on January 1, 2016 would not have had a significant impact on our results of operations for the three and six months ended June 30, 2016. These pro forma amounts are not necessarily indicative of the operating results that would have occurred if these transactions had occurred on such date. The pro forma adjustments are based on certain assumptions that we believe are reasonable.

(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 primary borrowing groups (as defined and described in note 8 ). 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 $72.2 million and ( $14.3 million ) during the three months ended June 30, 2017 and 2016 , respectively, and a net gain of $145.3 million and $7.1 million during the six months ended June 30, 2017 and 2016, respectively.

The fair values of the ITV Collar , the Sumitomo 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.

Including the effects of derivative instruments, original issue premiums or discounts and commitment fees, but excluding the impact of financing costs, our weighted average interest rate on our aggregate variable- and fixed-rate indebtedness was 4.77% (including 4.50% for the Liberty Global Group and 6.43% for the LiLAC Group ) at June 30, 2017 . For information regarding our derivative instruments, see note 5 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at June 30, 2017 without regard to covenant compliance calculations or other conditions precedent to borrowing. At June 30, 2017 , based on the applicable leverage-based restricted payment tests and leverage covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, and 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 (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 assume no changes from June 30, 2017 borrowing levels and are based on the applicable leverage-based restricted payment tests and covenant and other limitations in effect for each borrowing group at June 30, 2017 , both before and after considering the impact of the completion of the June 30, 2017 compliance requirements.
