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 and mobile services, with consolidated operations at September 30, 2015 in 14 countries. Through our wholly-owned subsidiary Virgin Media Inc. ( Virgin Media ), we provide video, broadband internet, fixed-line telephony and mobile services in the United Kingdom ( U.K. ) and Ireland. Through Ziggo Group Holding B.V. ( Ziggo Group Holding ), Unitymedia GmbH ( Unitymedia ), each a wholly-owned subsidiary, and Telenet Group Holding NV ( Telenet ), a 57.1% -owned subsidiary, we provide video, broadband internet, fixed-line telephony and mobile services in the Netherlands, Germany and Belgium, respectively. Through UPC Holding BV ( UPC Holding ), we provide (a) video, broadband internet and fixed-line telephony services in seven other European countries and (b) mobile services in four other European countries. The operations of Virgin Media , Ziggo Group Holding , Unitymedia , Telenet and UPC Holding are collectively referred to herein as the “ European Operations Division .” In Chile, we provide video, broadband internet, fixed-line telephony and mobile services through VTR GlobalCom SpA ( VTR ). In Puerto Rico, we provide video, broadband internet and fixed-line telephony services through Liberty Cablevision of Puerto Rico LLC ( Liberty Puerto Rico ), an entity in which we hold a 60.0% ownership interest. The operations of VTR and Liberty Puerto Rico are collectively referred to herein as the “ LiLAC Division .” On July 1, 2015, we completed the approved steps of the “ LiLAC Transaction ” whereby we (i) reclassified our then outstanding Class A, Class B and Class C Liberty Global ordinary shares (collectively, the Old Liberty Global Shares ) into corresponding classes of new Liberty Global ordinary shares (collectively, the Liberty Global Shares ) and (ii) capitalized a portion of our share premium account and distributed as a dividend (or a “bonus issue” under U.K. law) our LiLAC Class A, Class B and Class C ordinary shares (collectively, the LiLAC Shares ). Pursuant to the LiLAC Transaction , each holder of Class A, Class B and Class C Old Liberty Global Shares remained a holder of the same amount and class of Liberty Global Shares and received one share of the corresponding class of LiLAC Shares for each 20 Old Liberty Global Shares held as of the record date for such distribution. Accordingly, we issued 12,625,362 Class A, 523,626 Class B and 30,776,883 Class C LiLAC Shares . Cash was issued in lieu of fractional LiLAC Shares . The LiLAC Shares have a nominal value of $0.01 per share. The impact of the LiLAC Transaction on our capitalization and earnings (loss) per share presentation has been reflected in these condensed consolidated financial statements prospectively from July 1, 2015. Accordingly, (a) our net earnings (loss) attributed to Liberty Global Shares and LiLAC Shares relates to the period from July 1, 2015 through September 30, 2015 and (b) our net loss attributed to Old Liberty Global Shares relates to periods prior to July 1, 2015. 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 and described 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) VTR Finance B.V. ( VTR Finance ) and its subsidiaries, which include VTR , (ii) Lila Chile Holding BV ( Lila Chile Holding ), which is the parent entity of VTR Finance , (iii) LiLAC Holdings Inc. ( LiLAC Holdings ) and its subsidiaries, which include Liberty Puerto Rico , and (iv) prior to July 1, 2015, the costs associated with certain corporate employees of Liberty Global that are exclusively focused on the management of the LiLAC Group (the LiLAC Corporate Costs ). Effective July 1, 2015, these corporate employees were transferred to LiLAC Holdings . The “ Liberty Global Group ” comprises our businesses, assets and liabilities not attributed to the LiLAC Group , including Virgin Media , Ziggo Group Holding , Unitymedia , Telenet , UPC Holding , our corporate entities (excluding the LiLAC Corporate Costs ) 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. On January 31, 2014, we completed the sale of substantially all of the assets (the Chellomedia Disposal Group ) of Chellomedia B.V. ( Chellomedia ) (the Chellomedia Transaction ). Chellomedia held certain of our programming interests in Europe and Latin America. We have accounted for the sale of the Chellomedia Disposal Group as a discontinued operation in our condensed consolidated financial statements. Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ( 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 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 2014 consolidated financial statements and notes thereto included in our 2014 Annual Report on Form 10-K. The preparation of financial statements in conformity with 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 September 30, 2015 . Certain prior period amounts have been reclassified to conform to the current period presentation.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update ( ASU ) No. 2014-09, Revenue from Contracts with Customers ( ASU 2014-09 ), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 , as amended by ASU No. 2015-14, will replace existing revenue recognition guidance in GAAP when it becomes effective January 1, 2018. Early application is permitted, but no sooner than January 1, 2017. This new standard permits the use of either the retrospective or cumulative effect transition method. We are currently evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

Business Combinations [Abstract]
Acquisitions	Acquisitions Pending Acquisition On April 18, 2015, Telenet entered into a definitive agreement (the BASE Agreement ) to acquire BASE Company NV ( BASE ) for a purchase price of €1,324.4 million ( $1,480.9 million ). BASE is the third-largest mobile network operator in Belgium. We expect that this acquisition will provide Telenet with cost-effective long-term mobile access to effectively compete for future growth opportunities in the Belgium mobile market. Telenet intends to finance the acquisition of BASE through a combination of €1.0 billion ( $1.1 billion ) of new debt facilities and existing liquidity. The acquisition of BASE is subject to customary closing conditions, including merger approval from the relevant competition authorities, and is expected to close by the end of March 2016. The BASE Agreement provides that in the event the relevant competition authorities fail to approve the transaction, Telenet would be required to pay the seller a termination fee of €100.0 million ( $111.8 million ). 2015 Acquisition On June 3, 2015 , pursuant to a stock purchase agreement (the Choice Purchase Agreement ) with the parent of Puerto Rico Cable Acquisition Company Inc., dba Choice Cable TV ( Choice ) and following regulatory approval, one of our subsidiaries, together with investment funds affiliated with Searchlight Capital Partners, L.P. (collectively, Searchlight ), acquired 100% of Choice (the Choice Acquisition ). Choice is a cable and broadband services provider in Puerto Rico. We acquired Choice in order to achieve certain financial, operational, and strategic benefits through the integration of Choice with Liberty Puerto Rico . The combined business is 60% -owned by our company and 40% -owned by Searchlight . The purchase price for Choice of $276.4 million was funded through (i) Liberty Puerto Rico ’s incremental debt borrowings, net of discount and fees, of $259.1 million , (ii) cash of $10.5 million and (iii) an equity contribution from Searchlight of $6.8 million . We have accounted for the Choice Acquisition using the acquisition method of accounting, whereby the total purchase price was allocated to the acquired identifiable net assets of Choice 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 preliminary opening balance sheet for the Choice Acquisition at the June 3, 2015 acquisition date is presented in the following table. The preliminary opening balance sheet is subject to adjustment based on our final assessment of the fair values of the acquired identifiable assets and liabilities. Although most items in the valuation process remain open, the items with the highest likelihood of changing upon finalization of the valuation process include property and equipment, goodwill, intangible assets associated with franchise rights and customer relationships and income taxes (in millions): Cash and cash equivalents $ 3.6 Other current assets 7.9 Property and equipment, net 79.8 Goodwill (a) 51.7 Intangible assets subject to amortization, net (b) 59.1 Franchise rights 147.8 Other assets, net 0.3 Other accrued and current liabilities (13.3 ) Non-current deferred tax liabilities (60.5 ) Total purchase price (c) $ 276.4 _______________ (a) The goodwill recognized in connection with the Choice Acquisition is primarily attributable to (i) the ability to take advantage of Choice ’s existing advanced broadband communications network to gain immediate access to potential customers and (ii) substantial synergies that are expected to be achieved through the integration of Choice with Liberty Puerto Rico . The entire amount of goodwill is expected to be deductible for U.S. tax purposes. (b) Amount primarily includes intangible assets related to customer relationships. As of June 3, 2015 , the weighted average useful life of Choice ’s intangible assets was approximately ten years . (c) Excludes direct acquisition costs of $8.5 million , which are included in impairment, restructuring and other operating items, net, in our condensed consolidated statements of operations. 2014 Acquisition On November 11, 2014, we gained control of Ziggo Holding B.V. ( Ziggo ) through the acquisition of 136,603,794 additional Ziggo shares, which increased our ownership interest in Ziggo to 88.9% (the Ziggo Acquisition ). Ziggo is a provider of video, broadband internet, fixed-line telephony and mobile services in the Netherlands. From November 12, 2014 through November 19, 2014, we acquired 18,998,057 additional Ziggo shares, further increasing our ownership interest in Ziggo to 98.4% (the Ziggo NCI Acquisition ). In December 2014, we initiated a statutory squeeze-out procedure in accordance with the Dutch Civil Code (the Statutory Squeeze-out ) in order to acquire the remaining 3,162,605 Ziggo shares not tendered through November 19, 2014. Under the Statutory Squeeze-out , which was completed during the second quarter of 2015, Ziggo shareholders other than Liberty Global received cash consideration of €39.78 ( $47.29 at the applicable rates) per share, plus interest, for an aggregate of €125.9 million ( $142.2 million at the applicable rates). This amount was approved in April 2015 by the Enterprise Court in the Netherlands. For accounting purposes, (i) the Ziggo Acquisition was treated as the acquisition of Ziggo by Liberty Global and (ii) the Ziggo NCI Acquisition and the Statutory Squeeze-out were treated as the acquisitions of a noncontrolling interest. We received regulatory clearance from the European Commission for the Ziggo Acquisition on October 10, 2014. The clearance was conditioned upon our commitment to divest our Film1 channels to a third party and to carry Film1 on our network in the Netherlands for a period of three years . On July 21, 2015, we sold our Film1 channels to Sony Pictures Television Networks. Under the terms of the agreement, all five Film1 channels will continue to be carried on certain of our networks for a period of at least three years . In July 2015, the Dutch incumbent telecommunications operator filed an appeal against the European Commission regarding its decision to approve the Ziggo Acquisition . We are not a party to the appeal and we do not expect that the filing of this appeal will have any impact on the ongoing integration and development of our operations in the Netherlands. Pro Forma Information The following unaudited pro forma condensed consolidated operating results for the three months ended September 30, 2014 and the nine months ended September 30, 2015 and 2014 give effect to (i) the acquisition of 100% of Ziggo and (ii) the Choice Acquisition , as if they had been completed as of January 1, 2014. 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. In the following table, we present the revenue that is attributed to the Liberty Global Group and the LiLAC Group as if such revenue had been attributed to each group at the beginning of each period presented. However, our presentation of net earnings (loss) and basic and diluted earnings (loss) per share attributed to (a) Liberty Global Shares , (b) LiLAC Shares and (c) Old Liberty Global Shares only includes the results of operations for the periods during which these shares were outstanding. Accordingly, (1) our net earnings (loss) attributed to Liberty Global Shares and LiLAC Shares relates to the period from July 1, 2015 through September 30, 2015 and (2) our net loss attributed to Old Liberty Global Shares relates to periods prior to July 1, 2015. Three months ended Nine months ended September 30, September 30, 2014 2015 2014 in millions, except per share amounts Revenue: Liberty Global Group: Continuing operations $ 4,724.4 $ 12,772.8 $ 14,341.5 Discontinued operation — — 26.6 Total - Liberty Global Group 4,724.4 12,772.8 14,368.1 LiLAC Group 322.0 945.1 971.7 Intergroup eliminations — — (0.1 ) Total $ 5,046.4 $ 13,717.9 $ 15,339.7 Net earnings ( loss) attributable to Liberty Global shareholders: Liberty Global Shares $ — $ 102.9 $ — LiLAC Shares — 30.4 — Old Liberty Global Shares (12.3 ) (1,000.4 ) (658.3 ) Total $ (12.3 ) $ (867.1 ) $ (658.3 ) Basic and diluted loss attributable to Liberty Global shareholders per share: Liberty Global Shares $ 0.12 LiLAC Shares $ 0.69 Old Liberty Global Shares $ (0.01 ) $ (1.13 ) $ (0.73 ) Our condensed consolidated statements of operations for the three and nine months ended September 30, 2015 include revenue of $22.6 million and $30.0 million , respectively, and net earnings of $1.1 million and $1.2 million , respectively, attributable to Choice .

The aggregate purchase price of these additional ITV shares was financed through borrowings under a secured borrowing arrangement (the ITV Collar Loan ). This purchase increased our total ownership of ITV to 398,515,510 shares, or approximately 9.9% of the total outstanding shares of ITV as of June 30, 2015, the most current publicly-available information. All of the ITV shares we hold are subject to a share collar (the ITV Collar ) and pledged as collateral under the ITV Collar Loan . Under the terms of the ITV Collar , the counterparty has the right to re-use all of the pledged ITV shares. For additional information regarding the ITV Collar , see note 5 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In general, we seek to enter into derivative instruments to protect against (i) increases in the interest rates on our variable-rate debt and (ii) foreign currency movements, particularly with respect to borrowings that are denominated in a currency other than the functional currency of the borrowing entity. 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 Polish zloty ( PLN ) and the Romanian lei ( RON ). With the exception of a limited number of our foreign currency forward contracts, we do not apply hedge accounting to our derivative instruments. Accordingly, changes in the fair values of most of our derivative instruments are recorded in realized and unrealized gains or losses on derivative instruments, net, in our condensed consolidated statements of operations. The following table provides details of the fair values of our derivative instrument assets and liabilities: September 30, 2015 December 31, 2014 Current Long-term (a) Total Current Long-term (a) Total in millions Assets: Cross-currency and interest rate derivative contracts: Liberty Global Group $ 187.9 $ 1,348.2 $ 1,536.1 $ 443.6 $ 812.5 $ 1,256.1 LiLAC Group 7.6 310.4 318.0 — 101.2 101.2 Total cross-currency and interest rate derivative contracts (b) 195.5 1,658.6 1,854.1 443.6 913.7 1,357.3 Equity-related derivative instruments - Liberty Global Group (c) 74.3 480.5 554.8 — 400.2 400.2 Foreign currency forward contracts: Liberty Global Group 2.7 — 2.7 1.4 — 1.4 LiLAC Group 5.3 — 5.3 1.1 — 1.1 Total foreign currency forward contracts 8.0 — 8.0 2.5 — 2.5 Other - Liberty Global Group 0.6 1.0 1.6 0.5 0.9 1.4 Total assets: Liberty Global Group 265.5 1,829.7 2,095.2 445.5 1,213.6 1,659.1 LiLAC Group 12.9 310.4 323.3 1.1 101.2 102.3 Total $ 278.4 $ 2,140.1 $ 2,418.5 $ 446.6 $ 1,314.8 $ 1,761.4 Liabilities: Cross-currency and interest rate derivative contracts: Liberty Global Group $ 315.0 $ 1,352.7 $ 1,667.7 $ 987.9 $ 1,443.9 $ 2,431.8 LiLAC Group 3.5 19.3 22.8 39.5 — 39.5 Total cross-currency and interest rate derivative contracts (b) 318.5 1,372.0 1,690.5 1,027.4 1,443.9 2,471.3 Equity-related derivative instruments - Liberty Global Group (c) 35.6 — 35.6 15.3 73.1 88.4 Foreign currency forward contracts: Liberty Global Group 3.5 — 3.5 0.6 — 0.6 LiLAC Group — — — 0.2 — 0.2 Total foreign currency forward contracts 3.5 — 3.5 0.8 — 0.8 Other - Liberty Global Group 0.1 — 0.1 0.2 0.1 0.3 Total liabilities: Liberty Global Group 354.2 1,352.7 1,706.9 1,004.0 1,517.1 2,521.1 LiLAC Group 3.5 19.3 22.8 39.7 — 39.7 Total $ 357.7 $ 1,372.0 $ 1,729.7 $ 1,043.7 $ 1,517.1 $ 2,560.8 _______________ (a) Our long-term derivative assets and liabilities are included in other assets, net, and other long-term liabilities, respectively, in our condensed consolidated balance sheets. (b) We consider credit risk in our fair value assessments. As of September 30, 2015 and December 31, 2014 , (i) the fair values of our cross-currency and interest rate derivative contracts that represented assets have been reduced by credit risk valuation adjustments aggregating $74.9 million and $30.9 million , respectively, and (ii) the fair values of our cross-currency and interest rate derivative contracts that represented liabilities have been reduced by credit risk valuation adjustments aggregating $138.7 million and $64.6 million , respectively. The adjustments to our derivative assets relate to the credit risk associated with counterparty nonperformance, and the adjustments to our derivative liabilities relate to credit risk associated with our own nonperformance. In all cases, the adjustments take into account offsetting liability or asset positions within a given contract. Our determination of credit risk valuation adjustments generally is based on our and our counterparties’ credit risks, as observed in the credit default swap market and market quotations for certain of our subsidiaries’ debt instruments, as applicable. The changes in the credit risk valuation adjustments associated with our cross-currency and interest rate derivative contracts resulted in net losses of $29.9 million and $31.2 million during the three months ended September 30, 2015 and 2014 , respectively, and a net gain (loss) of $30.4 million and ( $80.1 million ) during the nine months ended September 30, 2015 and 2014 , 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 ITV Collar with respect to ITV shares held by our company at September 30, 2015 , (ii) the share collar (the Sumitomo Collar ) with respect to the shares of Sumitomo Corporation held by our company and (iii) Virgin Media ’s conversion hedges (the Virgin Media Capped Calls ) with respect to Virgin Media ’s 6.50% convertible senior notes. The fair values of our equity collars 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. In connection with our additional investment in ITV during the third quarter of 2015, we (a) modified the purchased put option and written call option strike prices within the ITV Collar and (b) increased our borrowings under the ITV Collar Loan , resulting in net cash received of $92.0 million . This amount includes $77.5 million of cash borrowings under the ITV Collar Loan that were not required to fund our acquisition of additional ITV shares and $14.5 million related to the ITV Collar modifications. Immediately prior to the completion of these modifications, the fair value of the ITV Collar was a $270.5 million liability. In connection with the ITV Collar modifications, this liability was effectively transferred on a non-cash basis to the principal amount of the ITV Collar Loan . For information regarding our investment in ITV , see note 4 . The details of our realized and unrealized gains (losses) on derivative instruments, net, are as follows: Three months ended Nine months ended September 30, September 30, 2015 2014 2015 2014 in millions Cross-currency and interest rate derivative contracts: Liberty Global Group $ 392.4 $ 462.6 $ 507.0 $ (117.7 ) LiLAC Group 139.9 148.7 217.5 23.1 Total cross-currency and interest rate derivative contracts 532.3 611.3 724.5 (94.6 ) Equity-related derivative instruments - Liberty Global Group: ITV Collar 103.1 (65.2 ) (55.8 ) (65.2 ) Sumitomo Collar 92.0 29.0 20.1 13.7 Ziggo Collar — (68.1 ) — (74.0 ) Other (1.3 ) 0.3 (0.2 ) 1.2 Total equity-related derivative instruments 193.8 (104.0 ) (35.9 ) (124.3 ) Foreign currency forward contracts: Liberty Global Group 10.8 19.6 (16.6 ) 39.2 LiLAC Group 5.3 1.9 8.3 2.7 Total foreign currency forward contracts 16.1 21.5 (8.3 ) 41.9 Other - Liberty Global Group (0.2 ) (0.9 ) 0.5 (0.3 ) Total Liberty Global Group 596.8 377.3 455.0 (203.1 ) Total LiLAC Group 145.2 150.6 225.8 25.8 Total $ 742.0 $ 527.9 $ 680.8 $ (177.3 ) The net cash received or paid related to our derivative instruments is classified as an operating, investing or financing activity in our condensed consolidated statements of cash flows based on the objective of the derivative instrument and the classification of the applicable underlying cash flows. For foreign currency forward contracts that are used to hedge capital expenditures, the net cash received or paid is classified as an adjustment to capital expenditures in our condensed consolidated statements of cash flows. For derivative contracts that are terminated prior to maturity, the cash paid or received upon termination that relates to future periods is classified as a financing activity. The classification of these net cash outflows is as follows: Nine months ended September 30, 2015 2014 in millions Operating activities: Liberty Global Group $ (159.3 ) $ (394.4 ) LiLAC Group (31.1 ) (21.1 ) Total operating activities (190.4 ) (415.5 ) Investing activities: Liberty Global Group 14.5 (16.6 ) LiLAC Group 0.6 — Total investing activities 15.1 (16.6 ) Financing activities: Liberty Global Group (298.8 ) (109.3 ) LiLAC Group — (37.4 ) Total financing activities (298.8 ) (146.7 ) Total cash outflows: Liberty Global Group (443.6 ) (520.3 ) LiLAC Group (30.5 ) (58.5 ) Total $ (474.1 ) $ (578.8 ) 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. Collateral is generally not posted by either party under the derivative instruments of our subsidiary borrowing groups. At September 30, 2015 , our exposure to counterparty credit risk included derivative assets with an aggregate fair value of $1,835.3 million . Details of our Derivative Instruments In the following tables, we present the details of the various categories of our subsidiaries’ derivative instruments. For each subsidiary with multiple derivative instruments that mature within the same calendar month, the notional amounts are shown in the aggregate, and interest rates are presented on a weighted average basis. In addition, for derivative instruments that were in effect as of September 30, 2015 , we present a single date that represents the applicable final maturity date. For derivative instruments that become effective subsequent to September 30, 2015 , we present a range of dates that represents the period covered by the applicable derivative instruments.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We use the fair value method to account for (i) certain of our investments and (ii) our derivative instruments. The reported fair values of these investments and derivative instruments as of September 30, 2015 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 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. GAAP provides for a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted market prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. We record transfers of assets or liabilities in or out of Levels 1, 2 or 3 at the beginning of the quarter during which the transfer occurred. During the nine months ended September 30, 2015 , no such transfers were made. All of our Level 2 inputs (interest rate futures, swap rates and certain of the inputs for our weighted average cost of capital calculations) and certain of our Level 3 inputs (forecasted volatilities and credit spreads) are obtained from pricing services. These inputs, or interpolations or extrapolations thereof, are used in our internal models to calculate, among other items, yield curves, forward interest and currency rates and weighted average cost of capital rates. In the normal course of business, we receive market value assessments from the counterparties to our derivative contracts. Although we compare these assessments to our internal valuations and investigate unexpected differences, we do not otherwise rely on counterparty quotes to determine the fair values of our derivative instruments. The midpoints of applicable bid and ask ranges generally are used as inputs for our internal valuations. For our investments in ITV and Sumitomo , the recurring fair value measurements are based on the quoted closing price of the respective shares at each reporting date. Accordingly, the valuations of these investments fall under Level 1 of the fair value hierarchy. Our other investments that we account for at fair value are privately-held companies, and therefore, quoted market prices are unavailable. The valuation technique we use for such investments is a combination of an income approach (discounted cash flow model based on forecasts) and a market approach (market multiples of similar businesses). With the exception of certain inputs for our weighted average cost of capital calculations that are derived from pricing services, the inputs used to value these investments are based on unobservable inputs derived from our assumptions. Therefore, the valuation of our privately-held investments falls under Level 3 of the fair value hierarchy. Any reasonably foreseeable changes in assumed levels of unobservable inputs for the valuations of our Level 3 investments would not be expected to have a material impact on our financial position or results of operations. The recurring fair value measurement of our equity-related derivative instruments are based on binomial option pricing models, which require the input of observable and unobservable variables such as exchange-traded equity prices, risk-free interest rates, dividend yields and forecasted volatilities of the underlying equity securities. The valuations of our equity-related derivative instruments are based on a combination of Level 1 inputs (exchange traded equity prices), Level 2 inputs (interest rate futures and swap rates) and Level 3 inputs (forecasted volatilities). As changes in volatilities could have a significant impact on the overall valuations, we have determined that these valuations fall under Level 3 of the fair value hierarchy. For the September 30, 2015 valuation of the ITV Collar , we used estimated volatilities ranging from 23.6% to 24.3% . At September 30, 2015 , the valuations of the Sumitomo Collar and the Virgin Media Capped Calls were not significantly impacted by forecasted volatilities. As further described in note 5 , we have entered into various derivative instruments to manage our interest rate and foreign currency exchange risk. The recurring fair value measurements of these derivative instruments are determined using discounted cash flow models. Most of the inputs to these discounted cash flow models consist of, or are derived from, observable Level 2 data for substantially the full term of these derivative instruments. This observable data includes most interest rate futures and swap rates, which are retrieved or derived from available market data. Although we may extrapolate or interpolate this data, we do not otherwise alter this data in performing our valuations. We incorporate a credit risk valuation adjustment in our fair value measurements to estimate the impact of both our own nonperformance risk and the nonperformance risk of our counterparties. Our and our counterparties’ credit spreads represent our most significant Level 3 inputs, and these inputs are used to derive the credit risk valuation adjustments with respect to our various interest rate and foreign currency derivative valuations. As we would not expect changes in our or our counterparties’ credit spreads to have a significant impact on the valuations of these derivative instruments, we have determined that these valuations fall under Level 2 of the fair value hierarchy. 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 and acquisition accounting. These nonrecurring valuations include the valuation of reporting units, customer relationship intangible assets, property and equipment and the implied value of goodwill. The valuation of private reporting units is based at least in part on discounted cash flow analyses. With the exception of certain inputs for our weighted average cost of capital and discount rate calculations that are derived from pricing services, the inputs used in our discounted cash flow analyses, such as forecasts of future cash flows, are based on our assumptions. The valuation of customer relationships is primarily based on an excess earnings methodology, which is a form of a discounted cash flow analysis. The excess earnings methodology requires us to estimate the specific cash flows expected from the customer relationship, considering such factors as estimated customer life, the revenue expected to be generated over the life of the customer, 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. During the nine months ended September 30, 2015 , we performed nonrecurring valuations for the purpose of determining the acquisition accounting for the Choice Acquisition . The discount rates used to value the customer relationships and franchise marketing rights acquired as a result of this acquisition were approximately 11.75% and 12.25% , respectively. For additional information, see note 3 . We did not perform any significant nonrecurring fair value measurements during the nine months ended September 30, 2014 . A summary of our assets and liabilities that are measured at fair value on a recurring basis is as follows: Fair value measurements at September 30, 2015 using: Description September 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 $ 1,854.1 $ — $ 1,854.1 $ — Equity-related derivative instruments 554.8 — — 554.8 Foreign currency forward contracts 8.0 — 8.0 — Other 1.6 — 1.6 — Total derivative instruments 2,418.5 — 1,863.7 554.8 Investments 2,256.5 1,923.0 — 333.5 Total assets $ 4,675.0 $ 1,923.0 $ 1,863.7 $ 888.3 Liabilities - derivative instruments: Cross-currency and interest rate derivative contracts $ 1,690.5 $ — $ 1,690.5 $ — Equity-related derivative instruments 35.6 — — 35.6 Foreign currency forward contracts 3.5 — 3.5 — Other 0.1 — 0.1 — Total liabilities $ 1,729.7 $ — $ 1,694.1 $ 35.6 Fair value measurements at December 31, 2014 using: Description December 31, 2014 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 $ 1,357.3 $ — $ 1,357.3 $ — Equity-related derivative instruments 400.2 — — 400.2 Foreign currency forward contracts 2.5 — 2.5 — Other 1.4 — 1.4 — Total derivative instruments 1,761.4 — 1,361.2 400.2 Investments 1,662.7 1,344.3 — 318.4 Total assets $ 3,424.1 $ 1,344.3 $ 1,361.2 $ 718.6 Liabilities - derivative instruments: Cross-currency and interest rate derivative contracts $ 2,471.3 $ — $ 2,471.3 $ — Equity-related derivative instruments 88.4 — — 88.4 Foreign currency forward contracts 0.8 — 0.8 — Other 0.3 — 0.3 — Total liabilities $ 2,560.8 $ — $ 2,472.4 $ 88.4 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 Equity-related derivative instruments Total in millions Balance of net assets at January 1, 2015 $ 318.4 $ 311.8 $ 630.2 Losses included in net loss (a): Realized and unrealized losses on derivative instruments, net — (35.9 ) (35.9 ) Realized and unrealized losses due to changes in fair values of certain investments, net (5.3 ) — (5.3 ) Adjustments resulting from the modification of the terms of the ITV Collar, net (b) — 256.0 256.0 Foreign currency translation adjustments and other, net 20.4 (12.7 ) 7.7 Balance of net assets at September 30, 2015 $ 333.5 $ 519.2 $ 852.7 _______________ (a) Most of these net losses relate to assets and liabilities that we continue to carry on our condensed consolidated balance sheet as of September 30, 2015 . (b) On July 30, 2015, we modified the terms of the ITV Collar in connection with our acquisition of additional ITV shares. In connection with these modifications, we effectively transferred a liability associated with the ITV Collar to the ITV Collar Loan and received cash from the counterparty.

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 5.2% (including 5.1% for the Liberty Global Group and 6.4% for the LiLAC Group ) at September 30, 2015 . For information regarding our derivative instruments, see note 5 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at September 30, 2015 without regard to covenant compliance calculations or other conditions precedent to borrowing. At September 30, 2015 , based on the applicable leverage and other financial covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, except that the aggregate availability under (i) the Ziggo Credit Facilities (as defined below) was limited to €609.0 million ( $681.0 million ) and (ii) the UPC Broadband Holding Bank Facility (as defined below) was limited to €481.6 million ( $538.5 million ). When the relevant September 30, 2015 compliance reporting requirements have been completed, and assuming no changes from September 30, 2015 borrowing levels, we anticipate that (1) the availability under the Ziggo Credit Facilities will be limited to €662.2 million ( $740.5 million ) and (2) the availability under the UPC Broadband Holding Bank Facility will be limited to €666.4 million ( $745.2 million ). In addition to these limitations, the debt instruments of our subsidiaries contain restricted payment tests that limit the amount that can be loaned or distributed to other Liberty Global subsidiaries and ultimately to Liberty Global . At September 30, 2015 , these restrictions did not impact our ability to access the liquidity of our subsidiaries to satisfy our corporate liquidity needs beyond what is described above, except that the availability to be loaned or distributed by Ziggo and Unitymedia was limited to €257.6 million ( $288.0 million ) and €202.1 million ( $226.0 million ), respectively. When the relevant September 30, 2015 compliance reporting requirements have been completed and assuming no changes from September 30, 2015 borrowing levels, we anticipate that (I) the availability to be loaned or distributed by Ziggo will be limited to €308.3 million ( $344.7 million ) and (II) the availability to be loaned or distributed by Unitymedia will be limited to €254.2 million ( $284.2 million ). For information regarding amounts under the Telenet Credit Facility that are not included in our unused borrowing capacity, see “Telenet Credit Facility” below . (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 . (d) Amounts include the impact of premiums and discounts, where applicable. (e) The VM Revolving Facility (as defined below) is a multi-currency revolving facility with maximum borrowing capacity equivalent to £675.0 million ( $1,021.3 million ). The outstanding balance at September 30, 2015 was borrowed in euros. (f) Effective with the July 1, 2015 completion of the LiLAC Transaction , the VM Convertible Notes are exchangeable under certain conditions for 14.0791 Class A Liberty Global Shares , 35.1665 Class C Liberty Global Shares and $910.51 in cash (without interest) for each $1,000 in principal amount of VM Convertible Notes exchanged. (g) On July 30, 2015, we financed an additional investment in ITV with borrowings under the ITV Collar Loan and modified the terms of the ITV Collar . As further described in note 5 , we also recorded a non-cash increase to the ITV Collar Loan in connection with the modifications to the ITV Collar . For additional information regarding our investment in ITV , see note 4 . (h) Represents amounts owed pursuant to interest-bearing vendor financing arrangements that are used to finance certain of our property and equipment additions, and to a lesser extent, certain of our operating expenses. These obligations are generally due within one year . At September 30, 2015 and December 31, 2014 , the amounts owed pursuant to these arrangements include $150.4 million and $101.7 million , respectively, of VAT that was paid on our behalf by the vendor. Repayments of vendor financing obligations are included in repayments and repurchases of debt and capital lease obligations in our condensed consolidated statements of cash flows. (i) Unused borrowing capacity relates to the senior secured revolving credit facility of entities within VTR , which includes a $160.0 million U.S. dollar facility (the VTR Dollar Credit Facility ) and a CLP 22.0 billion ( $31.6 million ) Chilean peso facility (the VTR Peso Credit Facility ), each of which were undrawn at September 30, 2015 . The VTR Dollar Credit Facility and the VTR Peso Credit Facility have fees on unused commitments of 1.1% and 1.34% per year, respectively. (j) In June 2015, we increased the principal amount outstanding under the Liberty Puerto Rico Bank Facility by $267.5 million ( $261.1 million carrying value after deducting the applicable discount). Substantially all of the net proceeds from this borrowing were used to fund a portion of the purchase price for the Choice Acquisition . For additional information regarding the Choice Acquisition , see note 3 .

Refinancing Transactions. On March 30, 2015, Virgin Media Secured Finance PLC ( Virgin Media Secured Finance ), a wholly-owned subsidiary of Virgin Media , issued (i) $500.0 million principal amount of 5.25% senior secured notes due January 15, 2026 (the Original 2026 VM Senior Secured Notes ) and (ii) the 2027 VM Senior Secured Notes . The net proceeds from the Original 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes were used to (a) redeem 10% of the principal amount of each of the following series of notes issued by Virgin Media Secured Finance : (1) the April 2021 VM Sterling Senior Secured Notes , (2) the April 2021 VM Dollar Senior Secured Notes and (3) the 2025 VM 5.5% Sterling Senior Secured Notes , each at a redemption price equal to 103% of the applicable redeemed principal amount in accordance with the indentures governing each of the notes, and (b) prepay in full the existing £375.0 million ( $567.4 million ) outstanding principal amount of term loan A ( VM Facility A ) and $400.0 million of the existing $2,755.0 million outstanding principal amount of term loan B ( VM Facility B ), each under the VM Credit Facility (as described below). In connection with these transactions, we recognized a loss on debt modification and extinguishment, net, of $30.1 million . This loss includes (I) the write-off of $17.9 million of deferred financing costs, (II) the payment of $10.7 million of redemption premium and (III) the write-off of $1.5 million of unamortized discount. On April 30, 2015, Virgin Media Secured Finance issued $500.0 million principal amount of 5.25% senior secured notes due January 15, 2026 (the Additional 2026 VM Senior Secured Notes and, together with the Original 2026 VM Senior Secured Notes , the 2026 VM Senior Secured Notes ). The Additional 2026 VM Senior Secured Notes were issued at 101% of par. The net proceeds from the Additional 2026 VM Senior Secured Notes were used to prepay $500.0 million of the outstanding principal amount of VM Facility B . In connection with this transaction, we recognized a loss on debt modification and extinguishment, net, of $9.4 million . This loss includes the write-off of (i) $7.5 million of deferred financing costs and (ii) $1.9 million of unamortized discount. The 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes are senior obligations of Virgin Media Secured Finance that rank equally with all of the existing and future senior debt of Virgin Media Secured Finance and are senior to all existing and future subordinated debt of Virgin Media Secured Finance . The 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes are guaranteed on a senior basis by Virgin Media and certain subsidiaries of Virgin Media (the VM Senior Secured Guarantors ) and are secured by liens on substantially all of the assets of Virgin Media Secured Finance and the VM Senior Secured Guarantors (except for Virgin Media ). The 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes contain certain customary incurrence-based covenants. For example, the ability to raise certain additional debt and make certain distributions or loans to other subsidiaries of Liberty Global is subject to a consolidated net leverage ratio test, as specified in the indenture. In addition, the 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes provide that any failure to pay principal prior to expiration of any applicable grace period, or any acceleration with respect to other indebtedness of £75.0 million ( $113.5 million ) or more in the aggregate of VMIH or the restricted subsidiaries (as specified in the indenture) is an event of default under the 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes . Subject to the circumstances described below, the 2026 VM Senior Secured Notes are non-callable until January 15, 2020 and the 2027 VM Senior Secured Notes are non-callable until January 15, 2021 (each, a “ Call Date ” ). At any time prior to the applicable Call Date , Virgin Media Secured Finance may redeem some or all of the 2026 VM Senior Secured Notes or the 2027 VM Senior Secured Notes (as applicable) by paying a “make-whole” premium, which is the present value of all remaining scheduled interest payments to the applicable Call Date using the discount rate (as specified in the indenture) as of the redemption date plus 50 basis points . Virgin Media Secured Finance may redeem some or all of the 2026 VM Senior Secured Notes or the 2027 VM Senior Secured Notes at the following redemption prices (expressed as a percentage of the principal amount) plus accrued and unpaid interest and additional amounts (as specified in the indenture), if any, to the applicable redemption date, if redeemed during the 12 -month period commencing on January 15 of the years set forth below: Redemption price Year 2026 VM Senior Secured Notes 2027 VM Senior Secured Notes 2020 102.625% N.A. 2021 101.313% 102.438% 2022 100.656% 101.219% 2023 100.000% 100.609% 2024 and thereafter 100.000% 100.000% Prior to the applicable Call Date , during each 12 -month period commencing on the date on which the 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes were issued, Virgin Media Secured Finance may redeem up to 10% of the principal amount of the 2026 VM Senior Secured Notes and the 2027 VM Senior Secured Notes at a redemption price equal to 103% of the principal amount thereof plus accrued and unpaid interest up to (but excluding) the redemption date. If VMIH or the restricted subsidiaries (as specified in the indenture) sell certain assets or if Virgin Media Communications Limited or certain of its subsidiaries experience specific changes in control, Virgin Media Secured Finance must offer to repurchase the relevant notes at a redemption price of 101% . VM Credit Facility The VM Credit Facility , as amended, is the senior secured credit facility of VMIH , together with certain other subsidiaries of Virgin Media . The details of our borrowings under the VM Credit Facility as of September 30, 2015 are summarized in the following table: VM Facility Maturity Interest rate Facility amount (in borrowing currency) Unused borrowing capacity Carrying value (a) in millions D June 30, 2022 LIBOR + 3.25% (b) £ 100.0 $ — $ 151.0 E June 30, 2023 LIBOR + 3.50% (b) £ 849.4 — 1,282.5 F June 30, 2023 LIBOR + 2.75% (b) $ 1,855.0 — 1,841.6 Revolving Facility (c) December 31, 2021 LIBOR + 2.75% (d) 853.7 167.7 Total $ 853.7 $ 3,442.8 _______________ (a) The carrying values of VM Facilities D, E and F include the impact of discounts.

In June 2015, (i) $1,855.0 million of commitments under the existing VM Facility B were effectively rolled into a new dollar denominated term loan ( VM Facility F ) and (ii) we amended the terms of our VM Revolving Facility (the VM Revolving Facility Amendment ) to extend the maturity to December 31, 2021, reduce the margin from 3.25% to 2.75% and increase the commitments by £15.0 million ( $22.7 million ). In connection with these transactions, we recognized a loss on debt modification and extinguishment, net, of $4.8 million . This loss includes (a) the write-off of $3.2 million of deferred financing costs, (b) the write-off of $0.8 million of unamortized discount and (c) the payment of $0.8 million of third-party costs. VM Facility F and the VM Revolving Facility Amendment contain certain amendments to the VM Credit Facility , including the deletion of the senior net debt to annualized EBITDA (as specified in the VM Credit Facility ) maintenance covenant and amending the total net debt to annualized EBITDA (as specified in the VM Credit Facility ) maintenance covenant to limit its application so that it applies only for the benefit of the revolving credit facility lenders when greater than one-third of the revolving credit facilities are drawn on the last day of the relevant ratio period. On July 30, 2015, the VM Credit Facility was amended and restated to reflect these and certain other amendments approved by the majority lenders under the VM Credit Facility .

This loss includes (i) the payment of $89.8 million of redemption premium and (ii) the write-off of $1.4 million of unamortized discount. The March 2015 UM Senior Secured Notes are (i) senior obligations of the UM Senior Secured Note Issuer s that rank equally with all of the existing and future senior debt of each UM Senior Secured Note Issuer and are senior to all existing and future subordinated debt of each of the UM Senior Secured Note Issuer s, (ii) guaranteed on a senior basis by Unitymedia and certain of its subsidiaries and (iii) secured by a first-ranking pledge over the shares of the UM Senior Secured Note Issuer s and certain other share and/or asset security of Unitymedia and certain of its subsidiaries. The March 2015 UM Senior Notes are senior obligations of Unitymedia that rank equally with all of the existing and future senior debt of Unitymedia and are senior to all existing and future subordinated debt of Unitymedia . The March 2015 UM Senior Notes are guaranteed on a senior subordinated basis by various subsidiaries of Unitymedia and are secured by a first-ranking pledge over the shares of Unitymedia and junior-priority share pledges and other asset security of certain subsidiaries of Unitymedia . We refer to the March 2015 UM Senior Secured Notes and the March 2015 UM Senior Notes as the “ 2015 UM Notes .” The 2015 UM Notes contain certain customary incurrence-based covenants. For example, the ability to raise certain additional debt and make certain distributions or loans to other subsidiaries of Liberty Global is subject to a consolidated net leverage ratio test, as specified in the applicable indenture. The 2015 UM Notes provide that any failure to pay principal prior to expiration of any applicable grace period, or any acceleration with respect to other indebtedness of €75.0 million ( $83.9 million ) or more in the aggregate of Unitymedia or a UM Senior Secured Note Issuer or any of the restricted subsidiaries (as specified in the applicable indenture) is an event of default under the 2015 UM Notes . Subject to the circumstances described below, the 2015 UM Notes are non-callable until January 15, 2021. At any time prior to January 15, 2021, the UM Senior Secured Note Issuer s or Unitymedia may redeem some or all of the 2015 UM Notes (as applicable) by paying a “make-whole” premium, which is the present value of all remaining scheduled interest payments to the redemption date using the discount rate (as specified in the applicable indenture) as of the redemption date plus 50 basis points . The UM Senior Secured Note Issuer s or Unitymedia (as applicable) may redeem some or all of the 2015 UM Notes at the following redemption prices (expressed as a percentage of the principal amount) plus accrued and unpaid interest and additional amounts (as specified in the applicable indenture), if any, to the redemption date, if redeemed during the 12 -month period commencing on January 15 of the years set forth below: Year Redemption price March 2015 UM Senior Secured Notes March 2015 UM Senior Notes 2021 101.750% 101.875% 2022 100.875% 100.938% 2023 100.438% 100.469% 2024 and thereafter 100.000% 100.000% Prior to January 15, 2021, during each 12 -month period commencing on the date on which the March 2015 UM Senior Secured Notes were issued, the UM Senior Secured Note Issuer s may redeem up to 10% of the principal amount of the March 2015 UM Senior Secured Notes at a redemption price equal to 103% of the principal amount thereof plus accrued and unpaid interest up to (but excluding) the redemption date. If Unitymedia or certain of its subsidiaries sell certain assets or experience specific changes in control, Unitymedia must offer to repurchase the 2015 UM Notes at a redemption price of 101% . UPC Broadband Holding Bank Facility The UPC Broadband Holding Bank Facility , as amended, is the senior secured credit facility of UPC Broadband Holding . The details of our borrowings under the UPC Broadband Holding Bank Facility as of September 30, 2015 are summarized in the following table: UPC Broadband Holding Facility Maturity Interest rate Facility amount (in borrowing currency) (a) Unused borrowing capacity (b) Carrying value in millions AC (c) November 15, 2021 7.250% $ 675.0 $ — $ 675.0 AD (c) January 15, 2022 6.875% $ 675.0 — 675.0 AH (d) June 30, 2021 LIBOR + 2.50% (e) $ 1,305.0 — 1,302.3 AK (c) January 15, 2027 4.000% € 600.0 — 670.9 AL (c) January 15, 2025 5.375% $ 1,140.0 — 1,140.0 AM December 31, 2021 EURIBOR + 2.75% € 990.1 1,051.2 55.9 Elimination of Facilities AC, AD, AK and AL in consolidation (c) — (3,160.9 ) Total $ 1,051.2 $ 1,358.2 _______________ (a) Except as described in (c) below, amounts represent total third-party facility amounts at September 30, 2015 without giving effect to the impact of discounts. (b) At September 30, 2015 , our availability under the UPC Broadband Holding Bank Facility was limited to €481.6 million ( $538.5 million ). When the relevant September 30, 2015 compliance reporting requirements have been completed and assuming no changes from the September 30, 2015 borrowing levels, we anticipate that our availability under the UPC Broadband Holding Bank Facility will be limited to €666.4 million ( $745.2 million ). UPC Facility AM has a fee on unused commitments of 1.1% per year. (c) Amounts relate to certain senior secured notes (the UPCB SPE Notes ) issued by special purpose financing entities (the UPCB SPE s ) that are consolidated by UPC Holding and Liberty Global . The proceeds from the UPCB SPE Notes were used to fund additional UPC Facilities AC, AD, AK and AL with our wholly-owned subsidiary UPC Financing Partnership ( UPC Financing ) as the borrower. Accordingly, the amounts outstanding under UPC Facilities AC, AD, AK and AL are eliminated in our condensed consolidated financial statements. (d) The carrying value of UPC Facility AH includes the impact of a discount. (e) UPC Facility AH has a LIBOR floor of 0.75% . Refinancing Transactions. During the first quarter of 2015, (i) a controlling interest in UPC Broadband Ireland Ltd. and its subsidiaries was transferred from a subsidiary of UPC Holding to a subsidiary of Virgin Media , and the remaining noncontrolling interest was transferred to another Liberty Global subsidiary (the UPC Ireland Transfer ) and (ii) UPC Nederland Holding I B.V. and its subsidiaries, including Ziggo Services B.V. ( Ziggo Services ), formerly known as UPC Nederland B.V., were transferred from a subsidiary of UPC Holding to a subsidiary of Ziggo Group Holding . UPC Holding used the cash consideration received for such transfers to prepay (a) in full the €500.0 million ( $559.1 million ) outstanding principal amount of UPC Facility V , together with accrued and unpaid interest and the related prepayment premium to UPCB Finance I Limited ( UPCB Finance I ) and, in turn UPCB Finance I used such proceeds to fully redeem the €500.0 million ( $559.1 million ) aggregate principal amount of its 7.625% senior secured notes (the UPCB Finance I Notes ), (b) €560.0 million ( $626.2 million ) of its €750.0 million ( $838.6 million ) outstanding principal amount of UPC Facility Y , together with accrued and unpaid interest and the related prepayment premium to UPCB Finance II Limited ( UPCB Finance II ) and, in turn UPCB Finance II used such proceeds to redeem €560.0 million ( $626.2 million ) of the €750.0 million ( $838.6 million ) aggregate principal amount of its 6.375% senior secured notes (the UPCB Finance II Notes ) and (c) the remaining €870.2 million ( $973.1 million ) outstanding principal amount of UPC Facility AG , together with accrued and unpaid interest. In connection with these transactions, we recognized a loss on debt modification and extinguishment, net, of $74.7 million . This loss includes (1) the payment of $

Accrued Income Taxes [Abstract]
Income Taxes	Income Taxes Income tax benefit (expense) attributable to our earnings (loss) from continuing operations before income taxes differs from the amounts computed using the applicable income tax rate as a result of the following factors: Three months ended Nine months ended September 30, September 30, 2015 2014 2015 2014 in millions Computed “expected” tax benefit (expense) (a) $ (27.6 ) $ (67.5 ) $ 148.3 $ 94.6 Change in valuation allowances (b): Decrease (33.5 ) (115.5 ) (419.8 ) (364.2 ) Increase (4.0 ) (100.4 ) 39.8 5.8 Tax effect of intercompany financing 39.1 41.4 115.8 122.9 International rate differences (b) (c): Increase 29.4 75.2 154.7 191.7 Decrease (4.7 ) (8.0 ) (39.2 ) (21.8 ) Basis and other differences in the treatment of items associated with investments in subsidiaries and affiliates (b): Decrease (61.1 ) (51.8 ) (88.8 ) (97.7 ) Increase (2.7 ) 33.6 9.1 37.9 Non-deductible or non-taxable interest and other expenses (b): Decrease (20.1 ) (42.2 ) (69.1 ) (126.4 ) Increase 10.4 14.1 33.7 45.2 Recognition of previously unrecognized tax benefits 20.2 — 33.8 28.8 Tax benefit associated with technology innovation 8.3 — 18.8 — Non-deductible or non-taxable foreign currency exchange results (b): Increase 29.3 36.1 31.5 36.7 Decrease 15.7 16.0 (14.2 ) (7.9 ) Enacted tax law and rate changes (1.5 ) 23.6 (0.4 ) 29.3 Other, net 5.3 (0.2 ) (3.6 ) (2.9 ) Total income tax benefit (expense) $ 2.5 $ (145.6 ) $ (49.6 ) $ (28.0 ) _______________ (a) The statutory or “expected” tax rates are the U.K. rates of 20.0% for the 2015 periods and 21.0% for 2014 periods. (b) Country jurisdictions giving rise to increases within the nine -month period are grouped together and shown separately from country jurisdictions giving rise to decreases within the nine -month period. (c) Amounts reflect adjustments (either an increase or a decrease) to “expected” tax benefit for statutory rates in jurisdictions in which we operate outside of the U.K. As of September 30, 2015 , our unrecognized tax benefits of $541.9 million included $278.4 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. We are currently undergoing income tax audits in the Czech Republic, Chile, Germany, the Netherlands, Slovakia, Switzerland and the U.S. In the U.S. , the consolidated income tax returns of Liberty Global, Inc. for 2009 through 2015 are under examination. We have received notices of adjustment from the Internal Revenue Service with respect to our 2013, 2010 and 2009 taxable income and we have entered into the appeals process with respect to the 2010 and 2009 matters. While we believe that the ultimate resolution of these proposed adjustments will not have a material impact on our consolidated financial position, results of operations or cash flows, no assurance can be given that this will be the case given the amounts involved and the complex nature of the related issues. During the next 12 months, it is reasonably possible that the resolution of ongoing examinations by tax authorities as well as expiration of statutes of limitation could result in significant reductions to our unrecognized tax benefits related to tax positions taken as of September 30, 2015 . The amount of any such reductions could range up to $250 million . 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based Compensation	Share-based Compensation Our share-based compensation expense is based on the share-based incentive awards held by our and our subsidiaries’ employees, including share-based incentive awards related to awards issued by Liberty Global . A summary of the aggregate share-based compensation expense that is included in our operating and SG&A expenses is set forth below: Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 in millions Liberty Global: Performance-based incentive awards (a) $ 55.4 $ 44.2 $ 126.0 $ 88.0 Other share-based incentive awards 66.1 25.1 116.6 77.5 Total Liberty Global (b) 121.5 69.3 242.6 165.5 Telenet share-based incentive awards 2.1 1.9 7.7 12.6 Other 1.4 1.9 2.7 4.5 Total $ 125.0 $ 73.1 $ 253.0 $ 182.6 Included in: Operating expense: Liberty Global Group $ 0.9 $ 0.5 $ 2.7 $ 4.5 LiLAC Group 0.2 0.5 0.5 1.4 Total operating expense 1.1 1.0 3.2 5.9 SG&A expense: Liberty Global Group 122.4 70.2 248.1 171.6 LiLAC Group (c) 1.5 1.9 1.7 5.1 Total SG&A expense 123.9 72.1 249.8 176.7 Total $ 125.0 $ 73.1 $ 253.0 $ 182.6 _______________ (a) Includes share-based compensation expense related to (i) Liberty Global performance-based restricted share units ( PSU s ), (ii) a challenge performance award plan for certain executive officers and key employees (the Challenge Performance Awards ) and (iii) the May 2014 grant of performance grant units ( PGUs ) to our Chief Executive Officer. The Challenge Performance Awards include performance-based share appreciation rights ( PSAR s ) and PSU s. (b) In connection with the LiLAC Transaction , the compensation committee of our board of directors approved modifications to our outstanding share-based incentive awards (the Award Modifications ) in accordance with the underlying share-based incentive plans. The objective of the compensation committee was to ensure a relatively unchanged intrinsic value of outstanding equity awards before and after the bonus issuance of the LiLAC Shares . The mechanism to modify outstanding share-based incentive awards, as approved by the compensation committee, utilized the volume-weighted average price of the respective shares for the five days prior to and the five days following the bonus issuance ( Modification VWAP s ). In order to determine if any incremental stock-based compensation expense should be recorded as a result of the Award Modifications , we are required to measure the changes in the fair values of the then outstanding share-based incentive awards using market prices immediately before and immediately after the Award Modifications . Due to declines in the share prices of our Class A and Class C Liberty Global Shares following the bonus issuance, the exercise prices of options, share appreciation rights ( SARs ) and PSAR s determined using the Modification VWAP s were lower than the exercise prices that would have resulted if the market prices immediately before and after the Award Modifications had been used. Accordingly, the Black-Scholes fair values of our options, SARs and PSAR s increased as a result of the Award Modifications , resulting in incremental stock-based compensation expense of $99.3 million . This amount includes $63.5 million of expense recognized during the third quarter of 2015 related to awards that vested on or prior to September 30, 2015 and $35.8 million of expense that will be recognized in future periods through 2019 as the related awards vest. (c) The amount for the nine-month period in 2015 includes the reversal of $1.8 million of share-based compensation expense, primarily related to forfeitures of unvested PSU s during the first quarter of 2015. The following table provides certain information related to share-based compensation expense not yet recognized for share-based incentive awards issued by Liberty Global as of September 30, 2015 : Liberty Global ordinary shares (a) Liberty Global performance-based awards (a) (b) Total compensation expense not yet recognized (in millions) $ 223.1 $ 126.2 Weighted average period remaining for expense recognition (in years) 2.9 1.1 _______________ (a) Amounts relate to awards granted or assumed by Liberty Global under (i) the Liberty Global 2014 Incentive Plan (as amended and restated effective February 24, 2015), (ii) the Liberty Global 2014 Nonemployee Director Incentive Plan, (iii) the Liberty Global, Inc. 2005 Incentive Plan (as amended and restated effective June 7, 2013), (iv) the Liberty Global, Inc. 2005 Nonemployee Director Incentive Plan (as amended and restated effective June 7, 2013) and (v) certain other incentive plans of Virgin Media , including Virgin Media ’s 2010 stock incentive plan.

Earnings Per Share [Abstract]
Earnings or Loss per Ordinary Share	Earnings or Loss per Share Basic earnings or loss per share ( EPS ) is computed by dividing net earnings or loss by the weighted average number of ordinary shares outstanding for the period. Diluted earnings or loss per share presents the dilutive effect, if any, on a per share basis of potential ordinary 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 , LiLAC Shares and Old Liberty Global Shares are set forth below: Three months ended Nine months ended September 30, September 30, 2015 2014 2015 2014 in millions Net earnings (loss) attributable to holders of: Liberty Global Shares (a) $ 102.9 $ — $ 102.9 $ — LiLAC Shares (a) 30.4 — 30.4 — Old Liberty Global Shares (b): Continuing operations — 157.1 (1,002.2 ) (505.1 ) Discontinued operation — — — 333.5 — 157.1 (1,002.2 ) (171.6 ) Net earnings (loss) attributable to Liberty Global shareholders $ 133.3 $ 157.1 $ (868.9 ) $ (171.6 ) _______________ (a) The amounts presented for the 2015 nine-month period relate to the period from July 1, 2015 through September 30, 2015. (b) The amounts presented for the 2015 nine-month period relate to the period from January 1, 2015 through June 30, 2015. The details of our weighted average ordinary shares outstanding are set forth below: Three months ended Nine months ended September 30, September 30, 2015 2014 2015 2014 Weighted average ordinary shares outstanding: Liberty Global Shares (a) Basic 872,802,928 872,802,928 Diluted 885,904,765 885,904,765 LiLAC Shares (a): Basic 43,905,783 43,905,783 Diluted 44,229,892 44,229,892 Old Liberty Global Shares (b): Basic 779,708,147 884,040,481 784,112,867 Diluted 790,086,341 884,040,481 784,112,867 _______________ (a) The amounts presented for the 2015 nine-month period relate to the period from July 1, 2015 through September 30, 2015. (b) The amounts presented for the 2015 nine-month period relate to the period from January 1, 2015 through June 30, 2015. Liberty Global Shares The details of the calculation of EPS with respect to Liberty Global Shares for the three months ended September 30, 2015 are set forth in the following table: Numerator: Net earnings attributable to holders of Liberty Global Shares (basic and diluted EPS computation) (in millions) $ 102.9 Denominator: Weighted average ordinary shares (basic EPS computation) 872,802,928 Incremental shares attributable to the assumed exercise of outstanding options, SARs and PSARs and the release of share units upon vesting (treasury stock method) 13,101,837 Weighted average ordinary shares (diluted EPS computation) 885,904,765 A total of 9.7 million options, SAR s, PSAR s and RSU s and 2.6 million shares issuable upon conversion of the VM Convertible Notes were excluded from the calculation of diluted earnings per share during the three months ended September 30, 2015 because their effect would have been anti-dilutive. LiLAC Shares The details of the calculation of EPS with respect to LiLAC Shares for the three months ended September 30, 2015 are set forth in the following table: Numerator: Net earnings attributable to holders of LiLAC Shares (basic and diluted EPS computation) (in millions) $ 30.4 Denominator: Weighted average ordinary shares (basic EPS computation) 43,905,783 Incremental shares attributable to the assumed exercise of outstanding options, SARs and PSARs and the release of share units upon vesting (treasury stock method) 324,109 Weighted average ordinary shares (diluted EPS computation) 44,229,892 A total of 0.7 million options, SAR s, PSAR s and RSU s were excluded from the calculation of diluted earnings per share during the three months ended September 30, 2015 because their effect would have been anti-dilutive. Old Liberty Global Shares The details of the calculation of EPS with respect to Old Liberty Global Shares for the three months ended September 30, 2014 are set forth in the following table: Numerator: Net earnings attributable to holders of Old Liberty Global Shares (basic and diluted EPS computation) (in millions) $ 157.1 Denominator: Weighted average ordinary shares (basic EPS computation) 779,708,147 Incremental shares attributable to the assumed exercise of outstanding options, SARs and PSARs and the release of share units upon vesting (treasury stock method) 10,378,194 Weighted average ordinary shares (diluted EPS computation) 790,086,341 A total of 10.7 million options, SAR s, PSAR s and RSU s and 2.6 million shares issuable upon conversion of the VM Convertible Notes were excluded from the calculation of diluted earnings per share during the three months ended September 30, 2014 because their effect would have been anti-dilutive. We reported losses from continuing operations attributable to holders of Old Liberty Global Shares for the six months ended June 30, 2015 and the nine months ended September 30, 2014. Therefore, the potentially dilutive effect at June 30, 2015 and September 30, 2014 of the following items was not included in the computation of diluted loss per share attributable to holders of Old Liberty Global Shares during these periods because their inclusion would have been anti-dilutive to the computation or, in the case of certain PSU s and 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 42.0 million and 42.2 million , respectively, (ii) the number of shares issuable pursuant to PSU s and PGUs of approximately 5.3 million and 5.5 million , respectively, and (iii) the aggregate number of shares issuable pursuant to obligations that may be settled in cash or shares of approximately 2.6 million and 2.6 million , respectively.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

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 programming contracts, network and connectivity commitments, non-cancellable operating leases, purchases of customer premises and other equipment and other items. The following table sets forth the U.S. dollar equivalents of such commitments as of September 30, 2015 : Payments due during: Remainder of 2015 2016 2017 2018 2019 2020 Thereafter Total in millions Programming commitments $ 247.5 $ 994.9 $ 886.9 $ 702.4 $ 265.8 $ 5.6 $ 2.2 $ 3,105.3 Network and connectivity commitments 222.2 351.3 236.7 121.6 85.1 56.5 915.5 1,988.9 Operating leases 43.6 153.3 127.6 109.3 88.7 56.4 287.7 866.6 Purchase commitments 376.2 204.9 65.7 12.1 4.3 — — 663.2 Other commitments 259.3 274.6 163.1 96.6 43.5 21.8 27.7 886.6 Total (a) $ 1,148.8 $ 1,979.0 $ 1,480.0 $ 1,042.0 $ 487.4 $ 140.3 $ 1,233.1 $ 7,510.6 _______________ (a) The commitments included in this table do not reflect any liabilities that are included in our September 30, 2015 condensed consolidated balance sheet. 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, during the nine months ended September 30, 2015 and 2014 , third-party programming and copyright costs incurred by our broadband communications and direct-to-home ( DTH ) operations aggregated $1,703.2 million (including $1,518.7 million for the Liberty Global Group and $184.5 million for the LiLAC Group ) and $1,586.4 million (including $1,410.6 million for the Liberty Global Group and $175.8 million for the LiLAC Group ), respectively. Network and connectivity commitments include (i) Telenet ’s commitments for certain operating costs associated with its leased network, (ii) commitments associated with our mobile virtual network operator ( MVNO ) agreements, (iii) service commitments associated with our network extension project in the U.K. and (iv) certain repair and maintenance, fiber capacity and energy commitments of Unitymedia . Effective October 1, 2015 , Telenet ’s commitments for certain operating costs are subject to adjustment based on changes in the network operating costs incurred by Telenet with respect to its own networks. These potential adjustments are not subject to reasonable estimation and, therefore, are not included in the above table. The amounts reflected in the above table with respect to certain of our MVNO commitments represent fixed minimum amounts payable under these agreements and, therefore, may be significantly less than the actual amounts we ultimately pay in these periods. Purchase commitments include unconditional and legally-binding obligations related to the purchase of customer premises and other equipment. Commitments arising from acquisition agreements are not reflected in the above table. For information regarding our commitments under acquisition agreements, 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 nine months ended September 30, 2015 and 2014 , 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. 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. However, the claim for compensation has not yet been quantified. At the introductory hearing, which was held on September 8, 2009 , the proceedings on appeal were postponed indefinitely at the request of Proximus . In parallel with the above proceedings, Proximus filed a complaint with the Government Commissioner seeking suspension of the approval by the PICs ’ board of directors of the agreement-in-principle and initiated suspension and annulment procedures before the Belgian Council of State against these approvals and subsequently against the board resolutions of the PICs approving the 2008 PICs Agreement . In this complaint, Proximus ’s primary argument was that the PICs should have organized a public market consultation before entering into the agreement-in-principal and the 2008 PICs Agreement . Proximus ’s efforts to suspend approval of these agreements were unsuccessful. In the annulment cases, the Belgian Council of State decided on May 2, 2012 to refer a number of questions of interpretation of European Union ( EU ) law for preliminary ruling to the European Court of Justice. On November 14, 2013, the European Court of Justice ruled that a majority of the reasons invoked by the PICs not to organize a market consultation were not overriding reasons of public interest to justify abolishing the PICs ’ duty to organize such consultation. The annulment case was subsequently resumed with the Belgian Council of State, which was required to follow the interpretation given by the European Court of Justice with respect to the points of EU law. On May 27, 2014, the Belgian Council of State ruled in favor of Proximus and annulled (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 . The Belgian Council of State ruling did not annul the 2008 PICs Agreement itself. Proximus may now resume the civil proceedings that are still pending with the Court of Appeal of Antwerp in order to have the 2008 PICs Agreement annulled and claim damages. It is possible that Proximus or another third party or public authority will initiate further legal proceedings in an attempt to annul the 2008 PICs Agreement . 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 only responsible for damages in excess of €20.0 million ( $22.4 million ). In light of the fact that Proximus has not quantified the amount of damages that it is seeking and we have no basis for assessing the amount of losses we would incur in the unlikely event that the 2008 PICs Agreement were to be annulled, we cannot provide a reasonable estimate of the range of loss that would be incurred in the event the ultimate resolution of this matter were to be unfavorable to Telenet . However, 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. 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 ( $85 million ) for 2012) by approximately two-thirds and the return of similarly calculated overpayments from 2009 through the ultimate settlement date, plus accrued interest. While we expect a decision by the court of first instance during 2015, 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. Vivendi Litigation. A wholly-owned subsidiary of our company is a plaintiff in certain litigation titled Liberty Media Corporation, et. al. v. Vivendi S.A. and Universal Studios. A predecessor of Liberty Global was a subsidiary of Liberty Media Corporation ( Liberty Media ) through June 6, 2004. In connection with Liberty Media ’s prosecution of the action, our subsidiary assigned its rights to Liberty Media in exchange for a contingent payout in the event Liberty Media recovered any amounts as a result of the action. Our subsidiary’s interest in any such recovery will be equal to 10% of the recovery amount, including any interest awarded, less the amount to be retained by Liberty Media for (i) all fees and expenses incurred by Liberty Media in connection with the action (including expenses to be incurred in connection with any appeals and the payment of certain deferred legal fees) and (ii) agreed upon interest on such fees and expenses. On January 17, 2013, following a jury trial, the court entered a final judgment in favor of the plaintiffs in the amount of €944 million ( $1,056 million ), including prejudgment interest. Vivendi S.A. and Universal Studios have filed a notice of appeal of the court’s final judgment to the Second Circuit Court of Appeals. As a result, the amount that our subsidiary may ultimately recover in connection with the final resolution of the action, if any, is uncertain. Any recovery by our company will not be reflected in our consolidated financial statements until such time as the final disposition of this matter has been reached. Liberty Puerto Rico Matter. In November 2012, we completed a business combination that resulted in, among other matters, the combination of our then operating subsidiary in Puerto Rico with San Juan Cable, LLC dba OneLink Communications ( OneLink ). In connection with this transaction (the OneLink Acquisition ), Liberty Puerto Rico , as the surviving entity, became a party to certain claims previously asserted by the incumbent telephone operator against OneLink based on alleged conduct of OneLink that occurred prior to the OneLink Acquisition (the PRTC Claim ). The PRTC Claim includes an allegation that OneLink acted in an anticompetitive manner in connection with a series of legal and regulatory proceedings it initiated against the incumbent telephone operator in Puerto Rico beginning in 2009. In March 2014, a separate class action claim was filed in Puerto Rico (the Class Action Claim ) containing allegations substantially similar to those asserted in the PRTC Claim , but alleging ongoing injury on behalf of a consumer class (as opposed to harm to a competitor). The former owners of OneLink have partially indemnified us through November 27, 2016 for any losses we may incur in connection with the PRTC Claim up to a specified maximum amount. However, the indemnity does not cover any potential losses resulting from the Class Action Claim . Liberty Puerto Rico has recorded a provision and a related indemnification asset representing its best estimate of the net loss that it may incur upon the ultimate resolution of the PRTC Claim . While Liberty Puerto Rico expects that the net amount required to satisfy these contingencies will not materially differ from the estimated amount it has accrued, no assurance can be given that the ultimate resolution of these matters will not have an adverse impact on our results of operations, cash flows or financial position in any given period. 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, as of June 23, 2014, access to the Telenet network had become operational and can be applied by wireless operator Mobistar SA ( Mobistar ). 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 April 2, 2013, the Belgium Regulatory Authorities issued a draft decision regarding the “retail-minus” tariffs of minus 35% for basic television (basic analog and digital video package) and minus 30% for the bundle of basic television and broadband internet services. 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). On October 4, 2013, the Belgium Regulatory Authorities notified a draft quantitative decision to the European Commission in which they changed the “retail-minus” tariffs to minus 30% for basic television (basic analog and digital video package) and to minus 23% for the bundle of basic television and broadband internet services. Even though the European Commission made a number of comments regarding the appropriateness of certain assumptions in the proposed costing methodology, the Belgium Regulatory Authorities adopted such “retail-minus” tariffs on December 11, 2013. During 2015, the Belgium Regulatory Authorities proposed that the basis for calculating the “retail minus” tariffs will be further reduced, which would lead to significantly lower “retail minus” tariffs. Following consultations regarding such proposals, the draft decision will then be sent for review to the European Commission. A final decision is expected prior to December 31, 2015. 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. Telenet is currently considering the possibility to file an appeal against this decision with the Belgian Supreme Court . Telenet also filed an appeal with the Brussels Court of Appeal against the decision regarding the quantitative aspects of the reference offers. Wireless operator Mobistar also filed an appeal against the decision regarding the quantitative aspects of the reference offers. A decision with respect to these appeals is not expected before the end of 2015. There can be no certainty that Telenet ’s appeals will be successful. The July 2011 Decision aims to, and in its application may, strengthen Telenet ’s competitors by granting them resale access to Telenet ’s network to offer competing products and services notwithstanding Telenet ’s substantial historical financial outlays in developing the infrastructure. In addition, any resale access granted to competitors could (i) limit the bandwidth available to Telenet to provide new or expanded products and services to the customers served by its network and (ii) adversely impact Telenet ’s ability to maintain or increase its revenue and cash flows. The extent of any such adverse impacts ultimately will be dependent on the extent that competitors take advantage of the resale access ultimately afforded to Telenet ’s network and other competitive factors or market developments. FCO Regulatory Issues. Our 2011 acquisition (the KBW Acquisition ) of the German cable network Kabel BW GmbH ( KBW ) was subject to the approval of The Federal Cartel Office (the FCO ) in Germany, which approval was received in December 2011. In January 2012, two of our competitors (collectively, the Appellants ), including the incumbent telecommunications operator, each filed an appeal (collectively, the FCO Appeals ) against the FCO regarding its decision to approve our KBW Acquisition . On August 14, 2013, the Düsseldorf Court of Appeal issued a ruling that set aside the FCO ’s clearance decision. During the fourth quarter of 2014, we, together with our German subsidiaries, entered into agreements with the Appellants pursuant to which the Appellants withdrew the FCO Appeals and, on January 21, 2015, the FCO consented to the withdrawal. On March 15, 2015, the Federal Court of Justice terminated the proceedings, as a result of which the FCO ’s clearance decision with respect to our KBW Acquisition became final (without any additional review or conditions). On April 29, 2015, we paid the Appellants an aggregate amount of €183.5 million ( $204.5 million at the transaction date), in satisfaction of the provision that we recorded during the fourth quarter of 2014. We consider this matter to be closed. Financial Transactions Tax. Eleven countries in the EU , including Belgium, 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 eleven participating countries. Although ongoing debate in the relevant countries demonstrates continued momentum around the FTT , uncertainty remains as to when the FTT would 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 January 2017. 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 the 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 £44.2 million ( $66.9 million ) as of September 30, 2015 . 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 court’s decision is expected prior to December 31, 2015. 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 Virgin Media offers to its fixed-line telephony customers. This change, which took effect on May 1, 2014, resulted in a $24.0 million decrease to Virgin Media ’s revenue during the first half of 2015 , as compared to the corresponding period in 2014 . Recent correspondence from the U.K. government indicates that it may seek to challenge Virgin Media ’s application of the prompt payment discount rules prior to the May 1, 2014 change in legislation. If such a challenge were to be issued by the U.K. government, Virgin Media could be required to make a payment of the challenged amount in order to make an appeal. Virgin Media currently estimates that the challenged amount could be up to approximately £65 million ( $98 million ) before any penalties or interest. Any challenge and subsequent appeal would likely be subject to court proceedings that could delay the ultimate resolution of this matter for an extended period of time. No portion of this potential exposure has been accrued by Virgin Media as no claim has been asserted or assessed and the likelihood of loss is not considered to be probable. Hungary VAT Matter. In September 2015, our DTH operations in Luxembourg received a first 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 have assessed our DTH operations with an obligation to pay VAT for the years audited of HUF 5,902.2 million ( $21.0 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. Although we are appealing the first instance decision, we may be required to pay all or a portion of the assessed amount during the pendency of the appeal. No portion of this exposure has been accrued by us as the likelihood of loss is not considered to be probable. Telenet MVNO Matter. Telenet and Mobistar are currently in dispute over amounts payable to Mobistar with respect to certain provisions of Telenet ’s MVNO agreement with Mobistar (the Mobistar MVNO Agreement ). As part of this dispute, Mobistar initiated legal proceedings against Telenet claiming, among other things, that the migration period after termination or expiration of the Mobistar MVNO Agreement should be shortened from 24 months to six months . Telenet believes it has strong arguments against Mobistar ’s claims and intends to defend itself vigorously. We cannot currently predict the outcome of these proceedings; however, in the unlikely event that the migration period is shortened, Telenet ’s mobile business could be adversely impacted. The oral hearing in this matter is currently scheduled for September 23, 2016. Other Regulatory Issues. Video distribution, broadband internet, fixed-line telephony, mobile and content businesses are regulated in each of the countries in which we 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 EU . 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. In this regard, beginning in September 2014, various decreases to tariff rates have been proposed and implemented by Chilean regulatory authorities, and a further decrease to one tariff rate is pending. None of these decreases had, or are expected to have, a material impact on VTR 's revenue or expenses. We have security accreditations across a range of business-to-business ( B2B ) products and services in order to increase our offerings to public sector organizations in the U.K. These accreditations are granted subject to periodic reviews of our policies and procedures by U.K. governmental authorities. If we were to fail to maintain these accreditations or obtain new accreditations when required, it could impact our ability to provide certain offerings to the public sector. 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 and wage, property and other tax issues and (iii) disputes over interconnection, programming, copyright and carriage fees. While we generally expect that the amounts required to satisfy these contingencies will not materially differ from any estimated amounts we have accrued, no assurance can be given that the resolution of one or more of these contingencies will not result in a material impact on our results of operations, cash flows or financial position in any given period. Due, in general, to the complexity of the issues involved and, in certain cases, the lack of a clear basis for predicting outcomes, we cannot provide a meaningful range of potential losses or cash outflows that might result from any unfavorable outcomes.

Segment Reporting, Measurement Disclosures [Abstract]
Segment Reporting	Segment Reporting We generally identify our reportable segments as those consolidated subsidiaries that represent 10% or more of our revenue, Adjusted OIBDA (as defined below) or total assets. 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 and is superior to available GAAP measures 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. We believe our Adjusted OIBDA measure is useful to investors because it is one of the bases for comparing our performance with the performance of other companies in the same or similar industries, although our measure may not be directly comparable to similar measures used by other public companies. Adjusted OIBDA should be viewed as a measure of operating performance that is a supplement to, and not a substitute for, operating income, net earnings or loss, cash flow from operating activities and other GAAP measures of income or cash flows. A reconciliation of total segment Adjusted OIBDA to our earnings (loss) from continuing operations before income taxes is presented below. During the fourth quarter of 2014, we began presenting (i) our operating segments in the U.K. and Ireland as one combined reportable segment, (ii) our operating segments in Switzerland and Austria as one combined reportable segment and (iii) our UPC DTH operating segment, as described below, as part of our Central and Eastern Europe reportable segment. These changes were made as a result of internal changes in organizational structures, changes in how these segments are evaluated and monitored by the chief operating decision maker and the integration of certain functions within these reportable segments. We began presenting our operating segment in Puerto Rico as a separate reportable segment during the second quarter of 2015 in anticipation of the issuance of the LiLAC Shares . Previously, (a) our operating segments in the U.K. and Switzerland were each separate reportable segments, (b) our operating segments in Ireland and Austria were combined into one reportable segment, “Other Western Europe,” (c) our UPC DTH operating segment was included in the European Operations Division ’s central and other category and (d) our operating segment in Puerto Rico was included in our corporate and other category. Segment information for all periods presented reflects the above-described changes. We present only the reportable segments of our continuing operations in the tables below. As of September 30, 2015 , our reportable segments are as follows: • European Operations Division : • U.K./Ireland • The Netherlands • Germany • Belgium • Switzerland/Austria • Central and Eastern Europe • LiLAC Division: • Chile • Puerto Rico All of the reportable segments set forth above derive their revenue primarily from broadband communications services, including video, broadband internet and fixed-line telephony services. Most of our reportable segments also provide B2B and mobile services. At September 30, 2015 , our operating segments in the European Operations Division provided broadband communications services in 12 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 Operations 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 Operations Division . The corporate and other category for the Liberty Global Group includes less significant consolidated operating segments that provide programming and other services. Intersegment eliminations primarily represent the elimination of intercompany transactions between our broadband communications and programming operations. Inter-group eliminations primarily represent the elimination of intercompany transactions between the Liberty Global Group and the LiLAC Group . 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 and Liberty Puerto Rico , 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 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.

Revenue by Major Category Our revenue by major category is set forth below: Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 in millions Subscription revenue (a): Video $ 1,591.0 $ 1,602.0 $ 4,808.3 $ 4,907.0 Broadband internet 1,293.4 1,174.2 3,809.3 3,508.7 Fixed-line telephony 796.1 798.5 2,397.2 2,457.9 Cable subscription revenue 3,680.5 3,574.7 11,014.8 10,873.6 Mobile subscription revenue (b) 270.1 281.6 783.0 812.0 Total subscription revenue 3,950.6 3,856.3 11,797.8 11,685.6 B2B revenue (c) 389.8 374.2 1,144.2 1,113.2 Other revenue (b) (d) 257.0 266.7 738.8 834.3 Total $ 4,597.4 $ 4,497.2 $ 13,680.8 $ 13,633.1 _______________ (a) Subscription revenue includes amounts received from subscribers for ongoing services, excluding installation fees and late fees. Subscription revenue from subscribers who purchase bundled services at a discounted rate is generally allocated proportionally to each service based on the standalone price for each individual service. As a result, changes in the standalone pricing of our cable and mobile products or the composition of bundles can contribute to changes in our product revenue categories from period to period. (b) Mobile subscription revenue excludes mobile interconnect revenue of $52.6 million and $60.4 million during the three months ended September 30, 2015 and 2014 , respectively, and $160.1 million and $184.2 million during the nine months ended September 30, 2015 and 2014 , respectively. Mobile interconnect revenue and revenue from mobile handset sales are included in other revenue. (c) B2B revenue includes revenue from business broadband internet, video, voice, mobile and data services offered to medium to large enterprises and, on a wholesale basis, to other operators. We also provide services to certain small office and home office ( SOHO ) subscribers. SOHO subscribers pay a premium price to receive expanded service levels along with video, broadband internet, fixed-line telephony or mobile services that are the same or similar to the mass marketed products offered to our residential subscribers.

(b) We consider credit risk in our fair value assessments. As of September 30, 2015 and December 31, 2014 , (i) the fair values of our cross-currency and interest rate derivative contracts that represented assets have been reduced by credit risk valuation adjustments aggregating $74.9 million and $30.9 million , respectively, and (ii) the fair values of our cross-currency and interest rate derivative contracts that represented liabilities have been reduced by credit risk valuation adjustments aggregating $138.7 million and $64.6 million , respectively. The adjustments to our derivative assets relate to the credit risk associated with counterparty nonperformance, and the adjustments to our derivative liabilities relate to credit risk associated with our own nonperformance. In all cases, the adjustments take into account offsetting liability or asset positions within a given contract. Our determination of credit risk valuation adjustments generally is based on our and our counterparties’ credit risks, as observed in the credit default swap market and market quotations for certain of our subsidiaries’ debt instruments, as applicable. The changes in the credit risk valuation adjustments associated with our cross-currency and interest rate derivative contracts resulted in net losses of $29.9 million and $31.2 million during the three months ended September 30, 2015 and 2014 , respectively, and a net gain (loss) of $30.4 million and ( $80.1 million ) during the nine months ended September 30, 2015 and 2014 , 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 ITV Collar with respect to ITV shares held by our company at September 30, 2015 , (ii) the share collar (the Sumitomo Collar ) with respect to the shares of Sumitomo Corporation held by our company and (iii) Virgin Media ’s conversion hedges (the Virgin Media Capped Calls ) with respect to Virgin Media ’s 6.50% convertible senior notes. The fair values of our equity collars 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. In connection with our additional investment in ITV during the third quarter of 2015, we (a) modified the purchased put option and written call option strike prices within the ITV Collar and (b) increased our borrowings under the ITV Collar Loan , resulting in net cash received of $92.0 million . This amount includes $77.5 million of cash borrowings under the ITV Collar Loan that were not required to fund our acquisition of additional ITV shares and $14.5 million related to the ITV Collar modifications. Immediately prior to the completion of these modifications, the fair value of the ITV Collar was a $270.5 million liability. In connection with the ITV Collar modifications, this liability was effectively transferred on a non-cash basis to the principal amount of the ITV Collar Loan . For information regarding our investment in ITV , see note 4 .

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 5.2% (including 5.1% for the Liberty Global Group and 6.4% for the LiLAC Group ) at September 30, 2015 . For information regarding our derivative instruments, see note 5 . (b) Unused borrowing capacity represents the maximum availability under the applicable facility at September 30, 2015 without regard to covenant compliance calculations or other conditions precedent to borrowing. At September 30, 2015 , based on the applicable leverage and other financial covenants, the full amount of unused borrowing capacity was available to be borrowed under each of the respective subsidiary facilities, except that the aggregate availability under (i) the Ziggo Credit Facilities (as defined below) was limited to €609.0 million ( $681.0 million ) and (ii) the UPC Broadband Holding Bank Facility (as defined below) was limited to €481.6 million ( $538.5 million ). When the relevant September 30, 2015 compliance reporting requirements have been completed, and assuming no changes from September 30, 2015 borrowing levels, we anticipate that (1) the availability under the Ziggo Credit Facilities will be limited to €662.2 million ( $740.5 million ) and (2) the availability under the UPC Broadband Holding Bank Facility will be limited to €666.4 million ( $745.2 million ). In addition to these limitations, the debt instruments of our subsidiaries contain restricted payment tests that limit the amount that can be loaned or distributed to other Liberty Global subsidiaries and ultimately to Liberty Global . At September 30, 2015 , these restrictions did not impact our ability to access the liquidity of our subsidiaries to satisfy our corporate liquidity needs beyond what is described above, except that the availability to be loaned or distributed by Ziggo and Unitymedia was limited to €257.6 million ( $288.0 million ) and €202.1 million ( $226.0 million ), respectively. When the relevant September 30, 2015 compliance reporting requirements have been completed and assuming no changes from September 30, 2015 borrowing levels, we anticipate that (I) the availability to be loaned or distributed by Ziggo will be limited to €308.3 million ( $344.7 million ) and (II) the availability to be loaned or distributed by Unitymedia will be limited to €254.2 million ( $284.2 million ). For information regarding amounts under the Telenet Credit Facility that are not included in our unused borrowing capacity, see “Telenet Credit Facility” below . (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 . (d) Amounts include the impact of premiums and discounts, where applicable. (e) The VM Revolving Facility (as defined below) is a multi-currency revolving facility with maximum borrowing capacity equivalent to £675.0 million ( $1,021.3 million ). The outstanding balance at September 30, 2015 was borrowed in euros. (f) Effective with the July 1, 2015 completion of the LiLAC Transaction , the VM Convertible Notes are exchangeable under certain conditions for 14.0791 Class A Liberty Global Shares , 35.1665 Class C Liberty Global Shares and $910.51 in cash (without interest) for each $1,000 in principal amount of VM Convertible Notes exchanged. (g) On July 30, 2015, we financed an additional investment in ITV with borrowings under the ITV Collar Loan and modified the terms of the ITV Collar . As further described in note 5 , we also recorded a non-cash increase to the ITV Collar Loan in connection with the modifications to the ITV Collar . For additional information regarding our investment in ITV , see note 4 . (h) Represents amounts owed pursuant to interest-bearing vendor financing arrangements that are used to finance certain of our property and equipment additions, and to a lesser extent, certain of our operating expenses. These obligations are generally due within one year . At September 30, 2015 and December 31, 2014 , the amounts owed pursuant to these arrangements include $150.4 million and $101.7 million , respectively, of VAT that was paid on our behalf by the vendor. Repayments of vendor financing obligations are included in repayments and repurchases of debt and capital lease obligations in our condensed consolidated statements of cash flows. (i) Unused borrowing capacity relates to the senior secured revolving credit facility of entities within VTR , which includes a $160.0 million U.S. dollar facility (the VTR Dollar Credit Facility ) and a CLP 22.0 billion ( $31.6 million ) Chilean peso facility (the VTR Peso Credit Facility ), each of which were undrawn at September 30, 2015 . The VTR Dollar Credit Facility and the VTR Peso Credit Facility have fees on unused commitments of 1.1% and 1.34% per year, respectively. (j) In June 2015, we increased the principal amount outstanding under the Liberty Puerto Rico Bank Facility by $267.5 million ( $261.1 million carrying value after deducting the applicable discount). Substantially all of the net proceeds from this borrowing were used to fund a portion of the purchase price for the Choice Acquisition .

The proceeds from the Telenet SPE Notes were used to fund additional Telenet Facilities O, P, U, V and AB with Telenet International as the borrower.

(d) On July 1, 2015, (i) the commitments under Telenet ’s revolving credit facilities were increased by €85.0 million ( $95.0 million ) ( Telenet Facility X2 ) and (ii) a lender under the then existing Telenet Facility S agreed to novate commitments of €10.0 million ( $11.2 million ) to a subsidiary of Telenet and enter into the new Telenet Facility X2 , which was subsequently merged with Telenet Facility X , resulting in total increased availability under Telenet Facility X of €95.0 million ( $106.2 million ).

Although Telenet currently has the ability, subject to certain restrictions and covenant limitations, to draw certain amounts under Telenet Facility Z and Telenet Facility AA for general corporate purposes, we expect that these facilities will remain undrawn until the closing of the acquisition of BASE . Accordingly, Telenet ’s unused borrowing capacity at September 30, 2015 excludes the availability under Telenet Facility Z and Telenet Facility AA . For information regarding the pending acquisition of BASE , see note 3 .

Summary of stock-based compensation	A summary of the aggregate share-based compensation expense that is included in our operating and SG&A expenses is set forth below: Three months ended September 30, Nine months ended September 30, 2015 2014 2015 2014 in millions Liberty Global: Performance-based incentive awards (a) $ 55.4 $ 44.2 $ 126.0 $ 88.0 Other share-based incentive awards 66.1 25.1 116.6 77.5 Total Liberty Global (b) 121.5 69.3 242.6 165.5 Telenet share-based incentive awards 2.1 1.9 7.7 12.6 Other 1.4 1.9 2.7 4.5 Total $ 125.0 $ 73.1 $ 253.0 $ 182.6 Included in: Operating expense: Liberty Global Group $ 0.9 $ 0.5 $ 2.7 $ 4.5 LiLAC Group 0.2 0.5 0.5 1.4 Total operating expense 1.1 1.0 3.2 5.9 SG&A expense: Liberty Global Group 122.4 70.2 248.1 171.6 LiLAC Group (c) 1.5 1.9 1.7 5.1 Total SG&A expense 123.9 72.1 249.8 176.7 Total $ 125.0 $ 73.1 $ 253.0 $ 182.6 _______________ (a) Includes share-based compensation expense related to (i) Liberty Global performance-based restricted share units ( PSU s ), (ii) a challenge performance award plan for certain executive officers and key employees (the Challenge Performance Awards ) and (iii) the May 2014 grant of performance grant units ( PGUs ) to our Chief Executive Officer. The Challenge Performance Awards include performance-based share appreciation rights ( PSAR s ) and PSU s. (b) In connection with the LiLAC Transaction , the compensation committee of our board of directors approved modifications to our outstanding share-based incentive awards (the Award Modifications ) in accordance with the underlying share-based incentive plans. The objective of the compensation committee was to ensure a relatively unchanged intrinsic value of outstanding equity awards before and after the bonus issuance of the LiLAC Shares . The mechanism to modify outstanding share-based incentive awards, as approved by the compensation committee, utilized the volume-weighted average price of the respective shares for the five days prior to and the five days following the bonus issuance ( Modification VWAP s ). In order to determine if any incremental stock-based compensation expense should be recorded as a result of the Award Modifications , we are required to measure the changes in the fair values of the then outstanding share-based incentive awards using market prices immediately before and immediately after the Award Modifications . Due to declines in the share prices of our Class A and Class C Liberty Global Shares following the bonus issuance, the exercise prices of options, share appreciation rights ( SARs ) and PSAR s determined using the Modification VWAP s were lower than the exercise prices that would have resulted if the market prices immediately before and after the Award Modifications had been used. Accordingly, the Black-Scholes fair values of our options, SARs and PSAR s increased as a result of the Award Modifications , resulting in incremental stock-based compensation expense of $99.3 million . This amount includes $63.5 million of expense recognized during the third quarter of 2015 related to awards that vested on or prior to September 30, 2015 and $35.8 million of expense that will be recognized in future periods through 2019 as the related awards vest. (c) The amount for the nine-month period in 2015 includes the reversal of $1.8 million of share-based compensation expense, primarily related to forfeitures of unvested PSU s during the first quarter of 2015.
